    Drivers and Barriers for Efficient Energy Management Practices in Energy-Intensive Industries: A Case-Study of Iron and Steel Sector2020Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 18, artikel-id 7703Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The two major reasons behind the worlds energy crisis are losses in energy transmission and less efficient energy use at sinks. The former flaw can be catered by changing the entire energy transmission system which requires investment and planning on a large scale, whereas the later deficiency can be overcome through proper management of energy utilizing systems. Energy-intensive industries have a substantial share in energy consumption and equally high energy saving potentials if they adopt some integrated and improved energy efficiency. This study investigates the energy management systems in the iron and steel sector of Pakistan, and compare it with findings of similar work in Sweden, Bangladesh, and Ghana. A systematic questionnaire was circulated in the iron and steel sector across the country and afterward the collected data was analyzed to find major barriers and drivers for efficient energy management practices. In addition, questions on non-energy benefits and information sources relevant to the energy efficiency were also part of the questionnaire. Cost reduction resulting from lowered energy use was rated as the most important driver for applying energy-efficient operation. On the other hand, the cost of production disruption was considered among high-level barriers to the implementation of improved energy efficiency. An increase in the life-time of equipment was labeled as the top non-energy benefits. Company peers and seminars/conferences were referred as the best information sources related to energy efficiency. The outcome of the study will be helpful to the decision-maker in the industry, as well as the government levels.

    Bending Fatigue Behavior of Blast Cleaned Grey Cast Iron2017Ingår i: Residual Stresses 2016: ICRS-10, Materials Research Proceedings 2 (2016), 2017, Vol. 2, s. 193-198Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a detailed study on the effect of an industrial blast cleaning process on the fatigue behavior of a grey cast iron with regard to the residual stresses and microstructural changes induced by the process. A comparison was also made to the effect of a machining operation which removed the casting skin layer. The blast cleaning process was found to greatly improve the fatigue resistance in both the low and high cycle regimes with a 75% increase in the fatigue limit. Xray diffraction measurements and scanning electron microscopic analyses showed that the improvement was mainly attributed to compressive residual stresses in a surface layer up to 800 μm in thickness in the blast cleaned specimens. The machining also gave better fatigue performance with a 30% increase in the fatigue limit, which was ascribed to the removal of the weaker casting skin layer.

    Massa, massa, massa ansvar: En intervjustudie kring förberedelsen inför vuxenblivandet,baserad på sex ungdomars röster2008Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [sv]

     

    Denna uppsats bygger på en kvalitativ studie av sex gymnasieelevers tankar kring förberedelsen inför vuxenblivandet samt skolans och familjens vägledande betydelse i denna process. Ungdomarnas verklighet stödjer de senmoderna teorierna om att dagens ungdomar försenas i sitt vuxenblivande i och med att studietiden har förlängts och därmed försenas även inträdet i arbetslivet. Ur samtalen med dessa ungdomar får vi inte bilden av att familjen och därav traditionen spelat ut sin roll, så som de senmoderna teoretikerna menar. Tvärtom framkommer det tydligt att familjen fortfarande innehar den centrala vägledande rollen i dessa ungdomars liv och leverne. Skolans roll i respondenternas förberedelse inför steget efter gymnasiet är inte samstämmig, då individualismen präglar några av informanterna, som ger uttryck för en mer långtgående individualiserad syn på sitt vuxenblivande. Detta resulterar i att dessa ungdomar starkt betonar sitt eget individuella ansvar framför skolans vägledande betydelse. Resultatet av denna studie visar att dessa ungdomar har bristande kunskaper vad gäller den praktiska delen i samhällssystemet samt att deras kunskapsnivå skiljer sig åt beroende på vilka kurser av ämnet samhällskunskap de har läst. Det är tydligt att de som har läst samhällskunskap C besitter mer kunskaper kring det praktiska i samhället. Som blivande samhällskunskapslärare anser vi att eleverna har rätt till denna kunskap oavsett gymnasieprogram, därav borde en obligatorisk kurs som belyser det praktiska aspekterna av samhällssystemet införas under det sista året på gymnasiet.

    On the intraday dynamics of oil price and exchange rate: What can we learn from China and India?2020Ingår i: Energy Economics, ISSN 0140-9883, E-ISSN 1873-6181, Vol. 91, artikel-id 104871Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The main aim of this paper is to investigate the volatility determinants of crude oil and foreign exchange markets and jump spillover between them. We consider currencies of two major oil-importing countries (India and China) over the sample period of January 1.2013 to October 31, 2019. We find evidence of positive return spillover from the oil to the foreign exchange market; however, there is a lack of return spillover in the other direction. Oil jumps appear to have a negative impact on exchange rate conditional volatility, and the latter responds asymmetrically to disentangled (positive and negative) oil price jumps. We also report disentangled exchange rate jumps significant impact on conditional oil price volatility. These results, however, are asymmetric based on the nature of jumps and alternative oil price series. Finally, we do not find evidence of co-jump between the oil and foreign exchange markets. These results have important implications for investors and policymakers. (C) 2020 Elsevier B.V. All rights reserved.

    Co-ethnic preferences in a cooking game: a study based on Come Dine With Me in Sweden2013Ingår i: Ethnic and Racial Studies, ISSN 0141-9870, E-ISSN 1466-4356, Vol. 36, nr 12, s. 2220-2236Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study examines ethnic preferences using data from the television cooking show Come Dine With Me in Sweden. Amateur chefs compete by hosting dinner parties. Contestants rate each others performance and the host with the highest ratings wins a cash prize. The show gives an unorthodox opportunity to study ethnic preferences in a high-stakes game environment. The analysis of the collected data shows that native Swedish contestants rate co-ethnic hosts significantly more favourably than they rate other hosts, demonstrating the existence of co-ethnic preferences. This observation seems to be an outcome of own-group favouritism rather than dislike against other groups. Also, the observed co-ethnic preference is assumed to be subtle or non-conscious based on the nature of the analysed data.

    Etnisk diskriminering - vad vet vi, vad behöver vi veta och vad kan vi göra?2015Ingår i: Ekonomisk Debatt, ISSN 0345-2646, Vol. 43, nr 4, s. 18-28Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    Diskriminering är ett avsevärt hinder på arbetsmarknaden, bostadsmarknaden och andra marknader för personer med utländsk bakgrund. I Sverige finns lagstiftning som förbjuder diskriminering och en myndighet som har tillsyn över problematiken. Men vad säger forskningen om etnisk diskriminering i Sverige? Denna översikt redogör för nationalekonomiska undersökningar som entydigt har funnit belägg för etnisk diskriminering. I ljuset av denna översikt förs en diskussion kring det vi känner till och det vi behöver känna till. Slutligen framförs förslag om hur arbetet mot etnisk diskriminering kan förbättras.

    Perceptions of gay, lesbian, and heterosexual domestic violence among undergraduates in Sweden2013Ingår i: International Journal of Conflict and Violence, E-ISSN 1864-1385, Vol. 7, nr 2, s. 249-260Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An experimental study of perceptions about gay, lesbian, and heterosexual domestic violence in Sweden. Undergraduate students (N = 1009) read one of eight fictitious scenarios of domestic violence in married couple relationships, where sexual orientation, sex of victim and batterer, and severity of violence were varied. Perceptions of seriousness of the described incident and attitudes toward women, gays and lesbians were measured. Domestic violence was perceived as more serious in cases where: the respondent was a woman, the batterer was a man, the victim was a woman, or the battering was severe. Wife-battering in a heterosexual relationship was considered the most serious case in both the less and more severe battering scenario. Where battering was less severe, domestic violence in gay and lesbian relationships was perceived as more serious than heterosexual husband-battering; this difference disappeared in the severe battering scenario. Negative attitudes toward gays, lesbians, and women were associated with less concern about domestic violence in all types of relationships. The findings suggest that stereotypes about gays, lesbians, and women affect perceptions of domestic violence, but mainly when violence is less severe.

    Are gay men and lesbians discriminated against in the hiring process?2013Ingår i: Southern Economic Journal, ISSN 0038-4038, E-ISSN 2325-8012, Vol. 79, nr 3, s. 565-585Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article presents the first field experiment on sexual orientation discrimination in the hiring process in the Swedish labor market. Job applications were sent to about 4000 employers in 10 different occupations in Sweden. Gender and sexual orientation were randomly assigned to applications. The results show that sexual orientation discrimination exists in the Swedish labor market. The discrimination against the gay male applicant and the lesbian applicant varied across different occupations and appears to be concentrated in the private sector. The results also show that the gay male applicant was discriminated against in typical male-dominated occupations, whereas the lesbian applicant was discriminated against in typical female-dominated occupations. Theoretical implications are discussed.

    Sexual orientation and full-time monthly earnings, by public and private sector: evidence from Swedish register data2013Ingår i: Review of Economics of the Household, ISSN 1569-5239, E-ISSN 1573-7152, Vol. 11, nr 1, s. 83-108Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this paper we explore annual earnings as well as full-time monthly earnings differentials resulting from sexual orientation. We observe that gay males are at an earnings disadvantage compared to male heterosexuals regardless of which earnings measure we use. This earnings disadvantage is found to be larger when we compare gay and heterosexual males who are working full-time. In addition, the disadvantage is larger in the private than in the public sector. Lesbians, however, earn more than heterosexual females. This earnings advantage is considerably smaller when we study full-time monthly rather than annual earnings but an earnings advantage for lesbians at the top of the earnings distribution is documented regardless of which earnings measure we use. In addition, lesbians are doing better than female heterosexuals in the public sector. To sum up, the results indicate that gay males face obstacles on the labor market that hinder them from reaching top-level positions and high earnings. The earnings advantage observed for lesbians is likely to stem from the fact that lesbians devote more time to market work than heterosexual females do.

    Does having ones own place to live make someone more employable?2017Ingår i: Applied Economics Letters, ISSN 1350-4851, E-ISSN 1466-4291, Vol. 24, nr 18, s. 1327-1330Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article encapsulates the findings of a randomized correspondence test field experiment investigating whether job candidates home status influences their employability. More than 2000 employers with vacancies in the Swedish labour market received a job application from a fictitious candidate. A job candidates home status (his or her own place to live or temporary housing with a friend) was randomized across employers. Results show that home status indeed affected the number of positive employer responses received by job candidates, mainly in low-skilled occupations. Not having a place to live at the time of the application proved a disadvantage when applying for positions within but an advantage when applying for positions outside the city of residence at the time of the application.

    Customer and Worker Discrimination against Gay and Lesbian Business Owners: A Web-Based Experiment among Students in Sweden2022Ingår i: Journal of Homosexuality, ISSN 0091-8369, E-ISSN 1540-3602, Vol. 69, nr 9, s. 1621-1630Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We examined customer and worker discrimination against gay and lesbian business owners using a web-based experiment conducted at a Swedish university campus. Participants (N = 1,406) were presented with a prospective restaurant establishment on the campus. They then stated whether they would be positive to such an establishment, whether they would be interested in working at the restaurant, and what their reservation wage would be if they were interested in the job. Owners sexual orientation was randomized across participants. Results showed that participants were less positive to a restaurant opening if the owners were lesbians, and they were less interested in an available job if the owners were gay. The participants had higher reservation wages if the owners were lesbians. In fact, the participants increased their wage demands when the number of women among the owners increased. Our study underlines that gay and lesbian people face various inequalities in society.

    Ethnic discrimination in contacts with public authorities: a correspondence test among swedish municipalities2020Ingår i: Applied Economics Letters, ISSN 1350-4851, E-ISSN 1466-4291, Vol. 27, nr 17, s. 1391-1394Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We present a field experiment conducted in order to explore the existence of ethnic discrimination in contact with public authorities. Two fictitious parents, one with a Swedish-sounding name and one with an Arabic-sounding name, sent email inquiries to all Swedish municipalities asking for information about preschool admission for their children. Results show that the parents were treated differently by the municipalities since the individual with the Swedish-sounding name received significantly more responses that answered the question in the inquiry than the individual with the Arabic-sounding name. Also, the individual with the Swedish-sounding name received more warm answers than the individual with the Arabic-sounding name in the sense that the answer from the municipality started with a personal salutation. We conclude that ethnic discrimination is prevalent in public sector contacts and that this discrimination has implications for the integration of immigrants and their children.

    Labor market discrimination: method and measurement2023Ingår i: Elgar Encyclopedia of Labour Studies / [ed] Tor Eriksson, Edward Elgar Publishing, 2023, s. 106-109Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    The development of methods for detecting labour market discrimination is characterized by a shift from observational data to different forms of experimental data. At the same time, there has been a shift from examining differences in treatment of groups of employees to differences in hiring.

    Observational data are associated with omitted variable problems. Field experiments in the form of audit and correspondence studies give better control of what is observed by both employers and the researcher. A limitation is that they can typically be employed only for certain types of (low-skill, early career) jobs and the initial (call-back) stage of the hiring process. Another is that employers’ beliefs cannot be controlled for. Natural and lab experiments can address some of these concerns. Most studies are not able to distinguish theories of between taste-based and statistical discrimination.

    Do schools discriminate against children with disabilities? A field experiment in Sweden2021Ingår i: Education Economics, ISSN 0964-5292, E-ISSN 1469-5782, Vol. 29, nr 1, s. 3-16Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article presents the results of a field experiment in which fictitious parents of children with attention deficit hyperactivity disorder (ADHD) and type 1 diabetes mellitus (T1DM) sent inquiries to schools in Sweden about admission of their children to the mandatory preschool class. Results show that inquiries concerning a child with no medical condition were more likely to receive an invitation for a visit and more likely to receive a promising placement response than inquiries concerning a child with ADHD and T1DM. Discrimination was more prominent in the private sector and when the child was a boy or had ADHD.

    Ethnic discrimination during the Covid-19 pandemic2023Ingår i: Migration and Integration in a Post-Pandemic World: Socioeconomic Opportunities and Challenges / [ed] Lin Lerpold, Örjan Sjöberg, & Karl Wennberg, Cham: Palgrave Macmillan , 2023, s. 291-314Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Ethnic discrimination is common in labor and housing markets. It leads to lower wages and higher unemployment for ethnic minorities, to segregation in the labor market, and to residential segregation. Several studies show that the Covid-19 pandemic increased the extent of ethnic discrimination. The prejudice against hiring migrants may have increased because people from countries where the epidemic started or from countries with a lower vaccination coverage were blamed for the spread. It may also have increased in the cases where the Covid-19 pandemic led to higher unemployment making it less costly for employers to discriminate.

    Abstract [en]

    Do employers discriminate against victims? We address this question and present the findings of a field experiment on hiring discrimination against victims. Matched pairs of written job applications for fictitious victims and nonvictims were sent to 1,117 employers in various labor market sectors. The probability of receiving a job interview invite or a job offer from employers was then estimated. Differences in this probability between the victim and nonvictim applicants were interpreted as discrimination. Results show that victims had a significantly lower probability of receiving a job interview invite or a job offer from employers than nonvictims. The extent of discrimination varied with applicants sex and occupational characteristics.

    Don’t be first! An empirical test of the first-mover disadvantage hypothesis in a culinary game show2019Ingår i: Social Sciences & Humanities Open, ISSN 2590-2911, Vol. 1, nr 1, s. 1-4, artikel-id 100004Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The purpose of the study presented in this paper was to evaluate the first-mover disadvantage hypothesis. Data from a Swedish television cooking game show was used to test the hypothesis. Each week four contestants on the game show take turns hosting each other at a dinner. Contestants rate each other’s performance and compete for a considerable cash prize. The contestant receiving the highest rating wins the cash prize at the end of the week. The results show that being the first contestant to host the dinner during a week remarkably reduced the chances of winning the cash prize in the end of that week. The results imply that being the first does not always pay off in some circumstances.

    The influence of energy consumption and democratic institutions on output and CO2 emissions in Bangladesh: a time-frequency approach2020Ingår i: Energy Systems, ISSN 1867-8998, E-ISSN 1867-9005, Vol. 11, nr 1, s. 195-212Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper reports the results of a study that investigates the causal interactions among the entities energy consumption, democracy, income, and CO2 emissions in Bangladesh. Bootstrapping causality and time–frequency domain causality methods were adopted to examine the causal co-movements between the variables, using data series for a period of more than four decades. Results show that time-scale behavior plays an important role. Democracy is an important factor for emissions and national income. The nexus of democracy and CO2 emission is bidirectional. The impact of democracy on CO2 is stronger than vice versa. This study provides new insights for policymakers: democratic practices play an important role in implementing climate change policies, at least in the case of Bangladesh.

    Gender discrimination in hiring: An experimental reexamination of the Swedish case2021Ingår i: PLOS ONE, E-ISSN 1932-6203, Vol. 16, nr 1, s. 1-15, artikel-id e0245513Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We estimated the degree of gender discrimination in Sweden across occupations using a correspondence study design. Our analysis of employer responses to more than 3,200 fictitious job applications across 15 occupations revealed that overall positive employer response rates were higher for women than men by almost 5 percentage points. We found that this gap was driven by employer responses in female-dominated occupations. Male applicants were about half as likely as female applicants to receive a positive employer response in female-dominated occupations. For male-dominated and mixed occupations we found no significant differences in positive employer responses between male and female applicants.

    Asymmetric dynamics between uncertainty and unemployment flows in the United States2020Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This paper examines how different uncertainty measures affect the unemployment level, inflow, and outflow in the U.S. across all states of the business cycle. We employ linear and nonlinear causality-in-quantile tests to capture a complete picture of the effect of uncertainty on U.S. unemployment. To verify whether there are any common effects across different uncertainty measures, we use monthly data on four uncertainty measures and on U.S. unemployment from January 1997 to August 2018. Our results corroborate the general predictions from a search and matching framework of how uncertainty affects unemployment and its flows. Fluctuations in uncertainty generate increases (upper-quantile changes) in the unemployment level and in the inflow. Conversely, shocks to uncertainty have a negative impact on U.S. unemployment outflow. Therefore, the effect of uncertainty is asymmetric depending on the states (quantiles) of U.S. unemployment and on the adopted unemployment measure. Our findings suggest statecontingent policies to stabilize the unemployment level when large uncertainty shocks occur.

    Are people fussy about who they work with? An experimental test of Becker’s coworker discrimination hypothesis2021Ingår i: The Social Science Journal, ISSN 0362-3319, E-ISSN 1873-5355, Vol. 58, nr 4, s. 477-483Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We used an experiment to investigate whether people’s decisions over employment opportunities are affected by the ethnicity and sex of their potential future coworkers. University students (N = 1,406) were asked to state the lowest hourly wage rate at which they would be willing to accept a job on a campus food truck, where they would work alongside the food truck owner. The ethnicity and sex of the food truck owners were randomized across participants. Results showed no signs of coworker prejudice in terms of the probability of being interested in the job and reservation wage.

    Customer discrimination in the fast food market: a web-based experiment on a Swedish university campus2020Ingår i: Migration Letters, ISSN 1741-8984, E-ISSN 1741-8992, Vol. 17, nr 6, s. 813-824Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents the results of a study that examined customer discrimination against fictitious male and female food truck owners with Arabic-sounding names on a Swedish university campus. In a web-based experiment, students (N = 1,406) were asked, in a market survey setting, whether they thought it was a good idea that a food truck was establishing on their campus and of their willingness to pay for a typical food truck meal. Four names—male and female Swedish-sounding names and male and female Arabic-sounding names—were randomly assigned to food trucks. We found no evidence of customer discrimination against food truck owners with Arabic-sounding names. Participants were slightly more positive to a food truck establishment run by a male with an Arabic-sounding name than a male with a Swedish-sounding name.

    Diskriminerar kunder utrikes födda företagare? Resultat från ett webb-baserat experiment2018Ingår i: Ekonomisk Debatt, ISSN 0345-2646, Vol. 46, nr 7, s. 25-32Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Vi presenterar resultat från ett experiment utfört på ett universitetscampus. Deltagarna fick se bilder av olika food-trucks och svara på om de tyckte det var en god idé att en food-truck etablerade sig på campusområdet samt ange sin betalningsvilja för olika varor. Deltagarna i experimentet var mer positiva till en etablering av en food-truck ägd av en man med arabiskt namn än till en etablering av en food-truck ägd av en man med svenskt namn. Resultaten är av intresse för integrationspolitiken, då de visar att egenföretagare med ursprung i Mellanöstern inte diskrimineras i en bransch där de ofta är verksamma.

    Utrikes födda personer särbehandlas i den skriftliga kontakten med landets kommuner. Det visar vårt experiment, där en man med svenskklingande namn fick bättre bemötande och mer information än en man med arabiskt namn. Diskrimineringen kan ge konsekvenser i form av sämre möjligheter till förskoleplats, skriver nationalekonomerna Ali Ahmed och Mats Hammarstedt.

    The employability of ex-offenders: a field experiment in the Swedish labor market2017Ingår i: IZA Journal of Labor Policy, E-ISSN 2193-9004, Vol. 6, nr 1, s. 1-23Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents the findings of a field experiment on hiring discrimination against ex-offenders in the Swedish labor market. Matched pairs of written job applications for fictitious male and female applicants with and without a past conviction of assault were sent to employers for nine different occupations. Results show that discrimination against ex-offenders exists, but the extent of it varies across occupations. The past conviction of assault was associated with 7–18 percentage point lower probability of receiving a positive employer response. Discrimination against ex-offenders was pronounced in female-dominated and high-skilled occupations. The magnitude of discrimination against ex-offenders did not vary by applicants’ sex.

    Choices at various levels of uncertainty: An experimental test of the restated diversification theorem2006Ingår i: Journal of Risk and Uncertainty, ISSN 0895-5646, E-ISSN 1573-0476, Vol. 33, nr 3, s. 183-196Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Our "Restated diversification theorem" (Skogh and Wu, 2005) says that risk-averse agents may pool risks efficiently without assignment of subjective probabilities to outcomes, also at genuine uncertainty. It suffices that the agents presume that they face equal risks. Here, the theorem is tested in an experiment where the probability of loss, and the information about this probability, varies. The result supports our theorem. Moreover, it tentatively supports an evolutionary theory of the insurance industry-starting with mutual pooling at uncertainty, turning into insurance priced ex ante when actuarial information is available. © Springer Science + Business Media, LLC 2006.

    Religious context and prosociality: an experimental study from Valparaíso, Chile2013Ingår i: Journal for the Scientific Study of Religion, ISSN 0021-8294, E-ISSN 1468-5906, Vol. 52, nr 3, s. 627-637Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Are people more prosocial in a religious context? We addressed this question through an experiment. We randomly placed participants in the control group in a neutral location (a lecture hall), and we placed participants in the experimental group in a religious location (a chapel). The participants then took part in a one-shot three-person public goods game, which measured participants' degree of cooperativeness. The results showed that participants in the experimental group cooperated significantly more than did participants in the control group. Furthermore, participants' beliefs about other participants' cooperativeness were more positive in the experimental group than they were in the control group. Improved expectations of others partially explained the enhanced cooperation in the religious context. We found no main or interaction effect of self-reported religiosity in the experiment.

    Biomass energy, technological progress and the environmental Kuznets curve: Evidence from selected European countries2016Ingår i: Biomass and Bioenergy, ISSN 0961-9534, E-ISSN 1873-2909, Vol. 90, s. 202-208Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We examine the causal relationship between economic growth and CO2 emissions in a panel of 24 European countries from 1980 to 2010. Using an analytical framework that considers pooled mean group estimations in a dynamic heterogeneous panel setting, we show that there is an inverted U-shaped relationship between CO2 emissions and economic growth in the long run and that there is no such relationship in the short run. In particular, we find that biomass energy is insignificantly linked to CO2 emission. However, technological innovation significantly facilitates reduction of CO2 emissions in the investigated countries. Altogether, our study implies that economic growth and environmental quality can be achieved simultaneously, which opens up new insights for policy-makers for sustainable economic development via implementation of renewable energy consumption through technological innovation.

    Working from home’s impact on Job Performance in the IT Sector2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this study is to examine which factors influence job performance for IT sector employees that are required to work from home indefinitely due to COVID-19. This study is based on a framework concerning themes such as working from home, performance, motivation, work-life balance, and psychological well-being.

    For the study, five IT sector employees that were required to work from home were interviewed to give the authors insight into the basis of the study. Previous studies mostly focused on IT sector employees working from home with the option of coming into the office; due to the sudden pandemic of COVID-19, there has not been much research regarding IT sector employees that are required to work from home indefinitely.

    Our most important findings show that employees are compensating their lack of in-person social interactions with spending time with family and using virtual apps to maintain their relationships with coworkers to provide a work-life balance. Working with coworkers has also given employees a sense of accountability that motivates them to do work. The virus, COVID-19 has impacted employees by mentally draining them which impacts their job performance. Ultimately, the idea of a job role perception and its impact on motivation and job performance is very subjective to the individual.

    On the effectiveness of foreign exchange reserves during the 2021-22 US monetary tightening cycle2023Ingår i: Economics Letters, ISSN 0165-1765, E-ISSN 1873-7374, Vol. 233, artikel-id 111367Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper examines whether the size of foreign exchange (FX) reserves explains cross-country differences in foreign currency depreciation realized over the 2021-22 Federal Reserve monetary policy tightening that led to a sharp appreciation of the US dollar. Across a broad sample of countries, we document that an additional 10 percentage points of FX reserves/GDP held ex-ante were associated with 1.5 to 2 percent less exchange rate depreciation against the US dollar and this buffer effect was larger among less financially developed economies. Effects were more pronounced for large-reserve countries that sold reserves to intervene than for large-reserve countries that did not intervene, supporting the presence of both balance sheet and intervention channels. Higher ex-ante policy rates were also associated with less depreciation especially among financially open economies. An analysis of daily currency movements following the June 2021 FOMC meeting corroborates the main results. These findings suggest that FX reserves may promote monetary policy independence in the presence of global spillovers.

    Improving Planning Stability: A case study of Planning at AstraZeneca2020Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    To provide high service level, an organisation must maintain flexibility in production planning. This allows them to react to changes in demand and supply information. Changes in production plan decreases planning stability. Low stability has knock on effect on supply of material. This causes disruptions in production and delivery as well as increased cost due to higher inventory cost, stockout costs, expediting cost and sub optimal setups cost. This study aims to determine the methods to improve planning stability. The factors that influence stability like planning horizon, safety stock, inventory policies are examined in detail in a real world setting.

    Literature review of existing work on planning stability was carried out. Single case study was used to study this phenomenon in depth at a pharmaceutical manufacturing company. Qualitative data regarding planning method, flow of information, interaction between departments, time horizons were studied. Quantitative data includes the production plans across different planning cycles. Existing stability levels were computed to determine the future levels of stability required. The literature was compared with existing working methods to find improvements.

    Plans away from the frozen period will have low stability due to forecast volatility. But as we move closer to frozen period, higher stability should be achieved. Low planning horizon in the immediate periods are due to material supply uncertainty which can be prevented by having responsible suppliers and increasing safety stocks. Using a stabilisation parameter can prevent rescheduling when small changes in demand occurs. This ensures unnecessary reaction to small changes are prevented.  Increasing the planning horizon will provide suppliers with accurate information regarding quantity and timing which will in turn help them plan better. Lastly, safety capacity in production can help towards handling unexpected production loses and thereby prevent re-planning.

    Drivers of eco-innovation2010Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Contemporary business world is now facing a challenge, a shift from traditional innovation to eco-innovation. Organizations need to recognize the importance of environment in any aspect of innovation. This paper aims to deduce the drivers of eco-innovation from the overview of existing literature and empirical study to provide an understanding of the organization aiming towards eco-innovation.

    The aim of this thesis is to identify the drivers of eco-innovation and objectives being able to understand and review the contribution of innovation and eco-innovation as separate entities.This research is limited to the investigation of drivers of eco-innovation in one single organization i.e. Tekniska Verken, Linköping. Conceptual model of drivers of eco-innovation is created from previous research and verified through empirical study. The model of this research is to outline the three categories of drivers within the limit and scope of this analysis. However modification of the model on the basis of additional drivers has been duly appreciated and elucidated to reflect reality of the research.

    Leveling Up & Closing the Gap!: Sustainable Fashion Consumers’ Journeys to New Levels of Sustainability2021Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Fashion democratization over the last few decades made fashion products available at lower costs to everyone in society. It alarmingly increased consumption, leaving drastic impacts on the world's sustainability both on the social and environmental fronts, thereby leading to water and land pollution, dangerous working conditions, sweatshops, wage exploitation, and gender discrimination. Our study, therefore, sheds some light on addressing this core problem of fashion sustainability by focusing on the problem from the consumers’ perspectives because researchers conclude that consumers hold power to mitigate this issue to a greater extent by becoming sustainable. However, in many cases, consumers show the attitude-behavior gap when it comes to consuming sustainable fashion. The area of actual sustainable fashion consumers is also under-researched.

    Therefore, we conducted our research in this area and used qualitative methods for it. We identified a small group of 16 sustainable transitional fashion consumers who have started their sustainable fashion consumption journey. We performed an inductive process study of these transitional consumers' journeys and developed a Conceptual ‘Consumer Journey Map’ from unsustainability towards sustainability. We used semi-structured interviews for data collection. By studying their entire process of transition, we identified a number of constraints that retained them from making the transition towards sustainable fashion consumption, such as Social Influence, Trend and Newness, Unaesthetic Appearance and Lack of Variety, Lacking Sizes and Fitting, Low price, and Lower Income, Lack of Knowledge and Information and Greenwashing by the brands. However, the enablers that pushed them to become sustainable were Influence from Sustainable social circles, Tangible Experiences, Quality and Longevity, and Feelings of guilt and remorse which are presented in ourconceptual ‘C-E Framework.'

    Our research also identified conceptual ‘Levels of Sustainability,’ where consumers reuse or reduceor reject to pass Level one. To reach Level two, a consumer has to begin combining any two of these behaviors. However, to reach the final Level X, a consumer needs to reuse, reduce, and reject simultaneously. A consumer passes through these different levels from being a ‘self’ consumer to be a ‘social’ one and finally converting into a ‘sacrifice’ consumer in their journey.

    Developing Common Questions about Integrated Product Service Engineering (IPSE), Ecodesign and Engineering Education2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In the recent years, more and more manufacturing firms recognize the benefit of providing products together with related services with an aim to gain higher profits as compared to supplying products without additional services. On the other hand, the competition in the global markets has been increased dramatically through increased sales of services in order to gain additional value for their products. In addition, several environmental challenges such as climate change, pollution, global warming impact, greenhouse gases emissions have played a vital role by influencing on the production protocols and trend of the companies. These challenges forced manufacturing countries to take into consideration environmentally conscious approach to their design thinking and industrial production processes. As a result, it became an important drive for manufacturing industries to shift from traditional product-oriented to service-oriented business models that has been witnessed during the last few years.

     

    The objective of this study research is to develop common questions that capture fundamental and common issues about Integrated Product Service Engineering (IPSE), Design for Environment (DFE) and Engineering education are effectives for industries to check and develop their knowledge, because the Engineering education plays a necessary role in associating socio-ethical knowledge with scientific and technological advances. The strategy taken to conduct this thesis task was first to study and understand the concept of Product Service System (PSS), IPSE, and Ecodesign as well as Engineering Education. Informative knowledge on these concepts were collected by reviewing several related journal articles, CIRP IPS2 conference proceedings.

     

    In this thesis the concepts of PSS, IPSE, DFE and Engineering Education discussed to develop the key common questions and issues to address the environmental, economic and social problems. Since PSS aims to reduce consumption through alternative schemes of product use as well as to increase overall resource productivity and dematerialization, but IPSE does not focus on a single factor but incorporates a wide range of factors such as environmental, social and economic issues. Whilst one of the main problems in this research focused on how to develop and strengthen the relationship between the academia and industry, and how this relation can be used to improve the academic performance and scientific research at universities and transfer them to industry.

     

    Sustainability and the life cycle concept have become a main solution for various problems such as a growing world population and a change in the industrial culture to come. As results Ecodesign and environmental considerations, financial aspects, product improvement as well as the commercial aspects were discussed in this project by understanding the previous concepts. The university considered as an important base of cultivating the talents, basic of inputs business organizations which help them to develop and improve their level of performance and quality of their products and services, and enhance its competitive position in the market. Changes in organized science further encouraged university interests in expanding technology transfer, because the scientific disciplines play an important role in influencing the type of interactions with industry as well as the University and Industry collaboration became the basic method of solving the problems to achieve (environmental, economic and social) sustainability.

    Shakedown in frictional contact of discrete elastic systems: A review2022Ingår i: International Journal of Solids and Structures, ISSN 0020-7683, E-ISSN 1879-2146, Vol. 241, artikel-id 111470Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    When exposed to cyclic quasi-static loading, elastic bodies in contact may develop a favourable condition where slip ceases after a few cycles, an occurrence commonly known as frictional shakedown. If the amplitude of the cyclic load is greater than a so-called shakedown limit, shakedown cannot occur. In this review paper, the validity of shakedown theorems in the context of conforming contacts with a la Coulomb friction is first discussed. Then, an optimisation method for determining the shakedown limit of elastic discrete three-dimensional systems is reviewed. Finally, an incremental Gauss-Seidel algorithm, extended to three-dimensional systems, is here illustrated in details for the first time. The algorithm allows us to describe the transient response of normal-tangential coupled systems under a given cyclic loading scenario, and to determine their possible shakedown depending on the initial conditions. An example concerning a discrete conforming contact problem, where either coupling or uncoupling conditions can be imposed, is illustrated.

    Fånge, hare eller hjort- En spelteoretisk analys av prisfallet på oljan2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Denna studie har till syfte att med hjälp av spelteorier analyser vilka incitament som låg bakom oljeprisfallet 2014 till 2016. Studien baseras på att pröva två spelteorier och analyserar vilken teori som har störst förklaringskraft på händelseförloppet. Händelseförloppet och oljemarknadens utveckling kommer att sammanställas utifrån aktuell data från myndigheter och nyhetssidor. Därefter kommer materialet att kategoriseras i olika huvudteman för att enklare kunna illustrera händelseförloppet och få en djupare förståelse. De två spelteorierna som studien baseras på är fångarnas dilemma och Stag Hunt samt försäkringsspelet som är en utvecklad version av Stag Hunt.Oljepriset under 2014 sjönk med 48,2 % på grund av massproduktionen av samtliga oljeproducenter. Detta påbörjades med hjälp av den nya kostsamma utvinningstekniken, fracking. Oljeproducenter som OPEC ökade sin produktion bland annat för att inte förlora sina marknadsandelar. Innan 2014 bestraffades oljeproducenter om produktionsnivån förändrades då det var en faktor som förhindrade upprätthållandet av ett högt oljepris. På oljemarknaden förekom svek, hot samt bestraffningar vilket indikerar på att fångarnas dilemma överensstämde med oljemarknaden.Oljeprisfallet 2014 orsakades av massproduktionen av främst USA. Oljeproducenterna hade då vetskap om USA:s mål vilket gjorde att en av förutsättningarna för fångarnas dilemma brast. Ur ett Stag Hunt perspektiv är oljeproducenternas pareotooptimala val att samarbeta. Däremot fick USA möjligheten att bli oberoende av importerad olja och valde därför att inte samarbeta med de resterande oljeproducenterna. För att inte riskera att förlora sina marknadsandelar var OPEC tvungna att försäkra sig genom att också avvika från samarbetet.

    Löpande informationsgivning från onoterade aktiebolag: Med sikte på gräsrotsfinansierade aktiebolag2017Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Gräsrotsfinansiering har under 2010-talet vuxit till att bli ett betydelsefullt finansierings-alternativ för små och medelstora företag, vilket även möjliggjort för privatpersoner (icke-professionella investerare) att investera i denna typ av bolag genom att teckna aktier i dem. Investeringar i bolag av mindre storlek kan potentiellt ge mycket god avkastning, men är även förenade med stor risk. Dessa investeringar kan fungera som ett komplement till sedvanliga investeringar på vad som i dagligt tal kallas för ”börsen”, men investeringar i småbolag skiljer mot aktiemarknadsbolag. Värdepappersmarknaden är föremål för rigorös reglering, i syfte att värna om ett starkt investerarskydd och upprätthålla förtroendet för marknaden. Mot bakgrund härav, föreligger högt ställda krav på aktiemarknadsbolagens löpande informationsgivning. Alla inträffade händelser och uppkomna förhållanden, vilka kan tänkas ha en påverkande effekt på aktiens pris ska, i regel, så snart som möjligt delges marknaden. På så vis ges alla befintliga och potentiella aktieägare en rättvis tillgång till information om bolaget, för att ha möjlighet att fatta välavvägda investeringsbeslut.

    Något motsvarande investerarskydd finns inte implementerat för investeringar i onoterade aktiebolag, utan investerare har få rättsliga medel för att tillskansa sig ytterligare information som kompletterar vad som utges under och i samband med bolagsstämman. Möjligheter till detta finns, men är praktiskt komplicerade att genomdriva.

    Detta ger upphov till frågan om balans råder mellan ett intresse att värna om investerare, å ena sidan, och ett intresse att underlätta företagande, å andra sidan. Gällande rätt är knappast ändamålsenlig, utan ändringar krävs för att råda bot på obalansen. Investerare bör ges utvidgad rätt till informationsgivning från onoterade aktiebolag när gräsrotsfinansiering tillämpats, eller om investerarkretsen annars är spridd. Krav på löpande informationsgivning av samma brådskande karaktär som råder på aktiemarknaden är emellertid inte önskvärt, utan vore alltför betungande för företagen. Därför föreslås istället kvartalsvis regelbunden informationsgivning från onoterade aktiebolag till investerarna, med komplettering av omedelbar informationsgivning av väsentliga händelser och förhållanden. Sådan reglering skulle tillförsäkra investerare en bättre ställning och hålla dem informerade om bolagets förehavanden, samtidigt som efterlevnaden inte vore oproportionerligt betungande för bolaget och dess befattningshavare.

    Abstract [en]

    Crowdfunding is a phenomenon that is subject to a great growth during the recent years, and the growth rate doesn't seem to stagnate. When new legislation named the JOBS Act in the U.S. becomes effective in late 2015, crowd equity will surely become a popular tool for financing businesses. Because crowdfunding great popularity is caused by the possibility to reach out to crowds through the internet, it is a global phenomenon, why it's relevant to examine current legislations in jurisdictions. This thesis covers an examination of Swedish laws of how they govern crowdfunding, and also suggestions on how the laws should be changed to more efficiently  correspond with the purposes of crowdfunding.

    Utformning av planerings- och styrningssystem för tillverkning av luckor till Boeing 787: en studie vid Saab Aerostructures2008Självständigt arbete på grundnivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats
    Abstract [sv]

    Saab Aerostructures är en del av Saab-koncernen och företaget utvecklar och tillverkar strukturer för flygindustrin. Tillverkningen av stridsflygplan är den dominerande verksamheten, men antalet civila projekt ökar stadigt. I många av de civila projekten verkar Saab Aerostructures som underleverantör till antingen Boeing eller Airbus. Det finns flera skillnader mellan de militära och de civila projekten, exempelvis är leveranstakten betydligt högre i de civila projekten. I och med de förändrade förutsättningarna görs försök med att tillämpa lean production. Detta har påbörjats i två pilotprojekt varav ett är tillverkningen av luckor till Boeing 787.

    Syftet med denna rapport är att komma med rekommendationer för hur produktionen av luckor till Boeing 787 skall planeras och styras. Då företaget började använda ett nytt ERP-system under hösten 2006, är det även av intresse att se hur detta system skall användas utefter de rekommendationer som uppkommer. För att utreda dessa frågor undersöks både produktionsstrategiska och operativa aspekter i de två produktionsavsnitten Sammanbyggnad och Kompositverkstad.

    Sammanlagt tillverkas sju olika luckor, varav de två största produceras i en lina som håller en jämn produktionstakt. Projektet är försenat, bland annat på grund av svårigheter att tillverka de 20 kompositartiklar som ingår i de tre största luckorna. Komposittillverkningen sker i en funktionell verkstad, med många transporter mellan byggnader för att knyta ihop flödet. Undersökningen visar att Saab Aerostructures har en mismatch mellan planeringsstrategin och den kapacitetsstrategi som tillämpas i Kompositverkstaden. Företaget försöker följa den efterfrågan de olika projekten har, men har samtidigt ont om kapacitet. Det leder till överbeläggning och leveranssvårigheter. På grund av kapacitetsbristen bör en cyklisk planering användas i Kompositverkstaden, där flaskhalsen styr takten. På detta sätt kan kötiderna i verkstaden minskas. Kompositverkstaden bör bli mer flödesinriktad för att minska ledtider och få till en enklare styrning. På detta sätt blir det möjligt att hålla en jämn leveranstakt även för dessa artiklar.

    Tillverkningstider, kötider och transporttider i ERP-systemet bör anpassas efter den cykliska planeringen som tas fram. Att uppdatera dessa tider blir extra viktigt i inkörningsförloppet, då tiderna är betydligt längre och varierar kraftigt. På grund av den hantverksmässiga produktionen i Kompositverkstaden och den stora kassationsrisken som föreligger är det viktigt att införa säkerhetsmekanismer. När den cykliska planeringen tas fram bör en säkerhetsledtid användas för de operationer som har stor variation i operationstid. För att inte linan skall stå stilla vid störningar är det även viktigt att skapa buffertar, dels innan linan men även framför den flaskhals som identifieras i flödet.

    Produktionstakten för kompositartiklarna är högre än takten i Sammanbyggnad, vilket inte stöds av ERP-systemet. För att systemet ändå skall föreslå rätt antal tillverkningsorder bör en kassationsfaktor användas. På detta sätt ges stöd för den långsiktiga planeringen. Slutligen visar undersökningen att styrning via ett kanbansystem ej bör genomföras, främst på grund av de höga kassationstalen och produktionsupplägget som en funktionell verkstad.

    Towards more efficient industrial lighting: Literature review on energy efficiency improvement of industrial lighting2023Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This master thesis work is aimed to investigate the possibilities of achieving more efficient industrial lighting. The study is divided in four parts: 1) Industrial lighting energy efficiency measures, 2) Added value of lighting, 3) Drivers and barriers for adopting lighting efficiency measures, and 4) Applications of AI in industrial lighting.The first part of the study explores various energy efficiency measures that could be applied in industrial lighting. The results show that using energy-efficient lighting fixtures, optimizing lighting controls, and adopting smart lighting solutions that integrate daylight in the illumination strategy and design are the most effective measures for reducing energy consumption and increasing efficiency.In the second part, the study examines the added values or non-energy benefitsof efficient industrial lighting. The findings indicate that apart from cost savings, efficient lighting leads to improvements on the quality of work environments, enhances workers health and safety conditions and improves environmental performance. Moreover, the study suggests that in many cases, the added values of lighting are not given the importance they should have and are not considered when an energy efficiency investment is planned to be done.The third part of the study identifies the drivers and barriers for adopting lighting efficiency measures in industrial settings. The study found that factors such as cost and energy savings, energy efficiency regulations are the main drivers for implementing efficient lighting solutions. However, barriers such as lack of awareness, perceived high initial costs, technology adoption and insufficient government incentives are the main obstacles to adoption.Finally, the study investigates the potential of artificial intelligence (AI) in industrial lighting. The results show that AI-based solutions, such as predictive maintenance and intelligent lighting control could significantly improve energy efficiency and reduce maintenance costs. Moreover, AI can bring the work environment to another level by the application of human centred and personalized lighting.Overall, this master thesis work provides valuable insights into achieving more efficient industrial lighting by highlighting effective energy efficiency measures, identifying the added value of efficient lighting, and examining the drivers and barriers to adoption. Moreover, the study sheds light on the potential of AI in industrial lighting and its potential benefits and future challenges.

    Servitization in SME manufacturing firms: A one-way road2015Ingår i: 13th International Research Symposium on Service Excellence in Management, Shanghai, June 19-21, 2015, 2015, s. 965-968Konferensbidrag (Refereegranskat)
    Abstract [en]

    The importance for manufacturing firms to add services to their offerings has been asserted over and over again (Neu and Brown 2005). Adding services to product sales require manufacturing firms to develop other types of offerings such as maintenance services, hybrid offerings or integrated solutions. This implies using new and often unknown practices to be able to provide services. Previous research has focused on the benefits of servitization (Gebauer, Gustafsson, and Witell 2011), albeit in larger firms. Hence, similar research on Small and Medium sized Enterprises (SME) has been scarce. Furthermore, servitization as a unidirectional transition process can be questioned as researchers argue that manufacturing firms might offer different types of services simultaneously and might not have the intention to take the next step that a transition process suggests (Kowalkowski et al. 2015). Moreover, previous research shows that the step from offering after-sales services and repair to offering more advanced services, e.g. process-related services, is rather big. For those services different mindsets are required within the organization; more advanced services would require a service oriented mindset, whereas after-sales services only requires the firm to have a product oriented mindset (Löfberg 2014).

    Operationalizing Industrial Ecology in the Waste Sector: Roles and tactics for circular value innovation2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. Lifting the waste management (WM) sector into a new phase of development, which takes its lead from the ideals of Industrial Ecology and circular economy, is seen by many scholars and practitioners as one potential to assist in alleviating these impacts. While there are many studies on how more efficient inter-organizational resource management is (or could be) constructed, there are relatively few business development studies which have explored novel approaches (from roles to tactics) that WM organizations might operationalize toward more efficient resource management.

    The aim of this thesis is to contribute to the development of knowledge and understanding of how the waste management sector can operationalize more effective and efficient resource management. In approaching this aim, two research questions guided the exploration of: 1) novel roles for WM and 2) support tactics for such roles. Grounded in the broader context of Industrial Ecology (IE) and Business Development, five studies were performed. Two studies, focused on the novel roles of inter-organizational resource management and high value secondary resource extraction, were performed through literature review and interviews, and market driver analysis respectively. In exploring support tactics, two design and proof of concept studies were carried out to investigate data analysis tools for inter-organizational resource management, and one long-term action research engagement project was coordinated to study hands-on inter-organizational collaboration tactics.

    The studies highlighted that the Swedish WM sector holds some key capacities for operationalizing (and in some cases, is already developing) the novel resource management roles identified: industrial symbiosis facilitator, eco-industrial park manager, holistic facility management, and high value resource extractor. However, depending on the portfolio of services to be performed in such roles, several capacities may need to be developed or strengthened. Main opportunities seen for these roles were – staying ahead of market developments, and aligning activities with organizational goals. The main general risk related to these roles was insufficient returns on investment. Looking forward, the main enablers identified were policy leadership for more balanced market mechanisms, increasing use of external knowledge, developing long term partnerships, lobbying, stockpiling resources, and carefully crafting new business models.

    The tools developed for strategically applying external information toward the identification of opportunities within new roles showed tactical potential. However, their implementation in broader development processes has yet to be fully validated. The hands-on exploration of change oriented collaboration, highlighted collective system framing and goal setting and face-to-face interaction as key activities for inter-organizational approaches within roles such as industrial symbiosis facilitator.

    Throughout the studies, several novel roles were investigated. Each of these roles will need to be individually evaluated by directing bodies of WM organizations, and evaluated from the organization’s vision and strategy. If certain roles are chosen to be explored in more detail, they will need to be developed within full business models - addressing issues such as income structure, internal processes and capacities to be developed, and key customers. Through applying IE and business development concepts and findings, WM organizations have possibilities to translate ambitious visions into novel offerings.

    Abstract [en]

    Several waste management (WM) professionals see an ongoing shift in the focus of the industry, from that of atransport and treatment sector to that of a more integrated sustainable service provision and material productionsector. To further develop such transitional ambitions, WM organizations are increasingly looking toward interorganizationalresource network concepts (such as the circular economy and industrial symbiosis) as models ofhow they would like to create new value together with their customers and partners.This article aims to take a step in addressing uncertainties behind such transitions by analyzing barriers forinter-organizational resource management and in turn uncovering some potential opportunities and risks ofnovel offerings from the WM sector. Obstacles for developing innovative inter-organizational resource networkshave been identified based on studies of implementing industrial symbiosis networks. Subsequently, managingexecutives from Swedish private and public WM organizations were interviewed regarding the sector’s capacityto overcome such barriers – opportunities and risks of providing new resource management services – and howtheir organizations might approach the role of actively facilitating more resource efficient regions.Eco-Industrial park management and contracting out holistic resource management are some areas in whichthe respondents see WM organizations offering new services. In relation to such approaches, various risks (e.g.being cut out of investment benefits, or unstable supply) and opportunities (e.g. new markets and enhancedsustainability profiles) were identified. Additionally, it was seen that WM companies would need to makesubstantial changes to their business approach, becoming less dependent on flows of mixed materials forexample, if they are to become even more central value chain actors. To strengthen such approaches, it was seenthat the sector will need to find methods to strategically build strong, long term partnerships, expand upon andtake advantage of available knowledge resources (i.e. best practice technologies and regional material flows),and explore new business models (i.e. stockpiling, park management, or waste minimization). Additionally,working with sector representatives to argue for a more balanced market conditions next to primary productionshould assist the viability of new offerings in the wider market.

    Even though it’s well known that our common resources are limited and that recycling is key for a sustainable future; inreality we see few examples of true recycling where virgin raw material is substituted by waste. There are endless numbers ofexamples where waste is utilized to some extent without solving the core issue: reducing the need of extracting virgin raw materials.This article analyses some of the driving forces and inhibitors of secondary stock extraction to explore why it’s so difficult establishlarge scale secondary stock extraction although suitable technologies are available. The authors discuss and suggest possible ways forreducing some of the main barriers presented.

    Abstract [en]

    Industrial symbiosis (IS) developments have been differentiated as self-organized, facilitated, and planned. This article introduces a tool, Looplocal, which has been built with objectives to support the strategic facilitation of IS. Looplocal is a visualization tool built to assist in 1) Simplifying the identification of regions susceptible to new industrial symbiosis facilitation activities 2) Enabling proactive and targeted marketing of potential exchanges to key actors in specific regions and 3) Assisting facilitators to assess the various strategies and consequential engagement and analysis methodologies suitable for additional IS development in specific regions. The tool compares industrial symbiosis data and estimated regional material and energy flows (on a facility level) to identify potential IS transfer information along with key stakeholder and network data. The authors have performed a proof of concept run of this tool on Sweden. In its early stages of application the method has given results seen as useful for identifying regions susceptible to the investment of symbiosis facilitators' time and resources. The material focus and customization possibilities for the tool show potential for a spectrum of potential facilitators: from waste management companies to national or regional authorities. In conjunction with long term business models, such a tool might be utilized throughout an adaptive chain of facilitation activities and aims.

    Abstract [en]

    Research on value pathways for organic wastes has been steadily increasing in recent decades. There have been few considerably broad overview studies of such materials and their valuation potential in the bio-based economy in part because of the vast multitude of materials and processes that can be used to produce energy carriers, chemicals, and materials of value. This article explores how automated data analysis approaches can help in analyzing large bodies of text to distill and present potential value pathways for secondary (waste) bio-based materials. The study employed multiple methods (literature collection, topic modelling, and co-occurrence analysis) on a collection of abstracts from 53,292 academic articles covering technologies, applications, and products (TAPs) for bio-based wastes. The results of both the topic modelling and co-occurrence analysis are presented as online interactive web pages. The topic modelling presented an overview of research clusters related to secondary organic resources, processes, and disciplines. The co-occurrence analysis helped to understand which TAPs are researched in relation to a broad spectrum of organic wastes. Co-occurrences were evaluated using the Normalized Pointwise Mutual Information measure to locate terms which co-occur more frequently than would be expected by chance. Through the use of detailed lists of organic wastes and TAPs, the co-occurrence method mapped out 7118 unique intersections between 473 specific wastes and 228 TAPs. This technique enables us to find seemingly non-obvious valorization pathways such as the re-use of oyster shells as catalysts for bio-diesel production and bioplastic production from brewery waste. While a proof-of-concept, this work points the way for using Big Data to suggest novel pathways for implementing the Circular Economy.

    Abstract [en]

    From 2009 until 2011 project BRA (Bygg-och Rivningsavfall i Stockholms Län) “Construction and Demolition (C&D) waste in Stockholm County” was coordinated from the division of Industrial Ecology, KTH. This project was focused on actively improving (from plural perspectives) the cycles of C&D (specifically non-metallic inert) materials in the region. In response to the normative aim and inter-systems complexity, a highly participative action research procedure was adopted. Through processes of network communication, workshops, a course, and an international symposium - a number of issues (such as market development, recycled product quality, greenhouse gas impacts, collaborative planning, and statistics) were prioritized, researched, and acted upon. Indicators for measuring progress in selected areas were developed and preliminary action plans created. At a final co-organized symposium Swedish delegates laid the groundwork for the establishment of a Swedish C&D recycling b ranch organization. This initiative of continued collaboration between and within sectors is seen as a vehicle for the priorities and action requirements identified in BRA to be further enabled and held in focus. Furthermore, these actors taking ownership of the process is seen as a success in accordance to the original aims and the need for further cycles of evaluation, planning, and action.

    Expanding roles for the Swedish waste management sector in interorganizational resource management2017Ingår i: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 124, s. 85-97Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several waste management (WM) professionals see an ongoing shift in the focus of the industry, from that of atransport and treatment sector to that of a more integrated sustainable service provision and material productionsector. To further develop such transitional ambitions, WM organizations are increasingly looking toward interorganizationalresource network concepts (such as the circular economy and industrial symbiosis) as models ofhow they would like to create new value together with their customers and partners.This article aims to take a step in addressing uncertainties behind such transitions by analyzing barriers forinter-organizational resource management and in turn uncovering some potential opportunities and risks ofnovel offerings from the WM sector. Obstacles for developing innovative inter-organizational resource networkshave been identified based on studies of implementing industrial symbiosis networks. Subsequently, managingexecutives from Swedish private and public WM organizations were interviewed regarding the sector’s capacityto overcome such barriers – opportunities and risks of providing new resource management services – and howtheir organizations might approach the role of actively facilitating more resource efficient regions.Eco-Industrial park management and contracting out holistic resource management are some areas in whichthe respondents see WM organizations offering new services. In relation to such approaches, various risks (e.g.being cut out of investment benefits, or unstable supply) and opportunities (e.g. new markets and enhancedsustainability profiles) were identified. Additionally, it was seen that WM companies would need to makesubstantial changes to their business approach, becoming less dependent on flows of mixed materials forexample, if they are to become even more central value chain actors. To strengthen such approaches, it was seenthat the sector will need to find methods to strategically build strong, long term partnerships, expand upon andtake advantage of available knowledge resources (i.e. best practice technologies and regional material flows),and explore new business models (i.e. stockpiling, park management, or waste minimization). Additionally,working with sector representatives to argue for a more balanced market conditions next to primary productionshould assist the viability of new offerings in the wider market.
