Exploring drivers of chemical risk management in Sweden : A Q-methodological study of the engineering industry in the Gnosjö region

Jakobsson, Maria January 2017 (has links)
Uncertainty about how chemicals affect human health and the environment, and shortcomings in current chemicals legislation, make it necessary to motivate chemical users to work actively with risk management in order to achieve a high level of protection. In this study, the drivers of chemical risk management have been investigated in order to find out how a pro-active work could be promoted. A Q-methodology study was performed online with 15 respondents at 10 different engineering companies in the Gnosjö region in Sweden. The respondents were part of the middle management and the local top management and had an environmental responsibility. Two groups with different views on drivers were identified. To comply with legislation was the main driver of the market-oriented group, while the plant-oriented group considered an improved work environment for employees as the main driver. A tendency to differences between how drivers were valued by middle management and local top management could be distinguished. The study indicated a need to motivate companies to stay ahead of legislation, as well as to enhance the understanding of the environmental impact that the operations have on the environment, and may be used as a basis for further studies of drivers of chemical risk management. / Osäkerhet om hur kemikalier påverkar människors hälsa och miljön samt brister i nuvarande kemikalielagstiftning gör att företag som hanterar kemikalier behöver motiveras till att arbeta aktivt med riskhantering för att en hög skyddsninvå ska kunna uppnås. I föreliggande studie har drivkrafterna bakom arbetet med riskantering av kemikalier undersökts i syfte att ta reda på hur ett proaktivt arbete skulle kunna främjas. En Q-metodologistudie genomfördes online med 15 respondenter på 10 olika verkstadsföretag i Gnosjöregionen i Sverige. Respondenterna utgjordes av personer på mellanchefs- och ledningsgruppsnivå med miljöansvar. Två grupper med olika syn på drivkrafter identifierades. Att uppfylla lagstifning var den viktigaste drivkraften för den marknadsorienterade gruppen, medan den fabriksorienterade gruppen betraktade en förbättrad arbetsmiljö för anställda som den viktigaste drivkraften. En tendens till skillnad i hur drivkrafter värderades på mellanchefs- och ledningsgruppsnivå kunde urskiljas. Studien indikerade ett behov av att motivera företagen till att ligga steget före lagstiftning, samt att öka förståelsen för verksamheternas påverkan på miljön och kan ligga till grund för fortsatta studier rörande drivkrafter bakom riskhantering av kemikalier.

Additive   manufacturing   of   spare   parts   for   the  mining   industry  a   pilot   study   on   business   impact   from   an   aftermarket   perspective.

Vingerhagen, Kristian, Alfredsson, Julia January 2021 (has links)
The   purpose   of   this   pilot   study   was   to   identify   and   evaluate   different   business   cases   for   Epiroc’s  Parts   &   Services   Division   (PSD)   regarding   the   use   of   additive   manufacturing   (AM),   also   known   as  3D   printing,   for   their   spare   parts   within   the   mining   industry.    This   study   presents   an   approach   for  how   spare   parts   promising   for   AM   can   be   identified   and   shows   the   difficulties   with   AM.   The   study  follows   the   design   research   methodology   (DRM)   standard   for   research   within   product   and   process  development.   Through   interviews   and   literature   searches,   a   "top-down"   approach   was   applied.   A  developed   cost-benefit   model   accompanied   this   approach   and   was   used   to   identify   and   evaluate  potential   spare   parts   for   AM   from   Epiroc’s   current   spare   parts   portfolio.   The   results   were   evaluated  as   promising   for   several   of   the   spare   parts   in   terms   of   reduced   manufacturing,   procurement,   tool  cost,   and   lead   time   reduction,   which   results   in   increased   uptime   for   the   customer.   With   reduced   lead  times,   the   availability   increases   for   the   customer,   who   may   increase   Epiroc’s   sales   and   aftermarket  revenues   in   the   long   run.   There   is   also   great   potential   for   reducing   the   costs   for   warehousing,   where  spare   parts   of   low   demand   can   have   their   stocks   reduced   or   eliminated   by   securing   supply   through  on-demand   manufacturing.   Although   many   exciting   business   cases   have   been   identified   and  evaluated,   it   has   been   acknowledged   that   CNC-machining   in   many   cases   is   the   cheaper   alternative.  Despite   this,   it   is   worth   investing   in   AM   from   a   strategic   point   of   view   as   it   is   seen   as   a   tool   for   the  future.   Before   it   can   be   adopted   and   implemented,   Epiroc   should   do   test   trials   with   companies  offering   AM   services.   These   can   be   used   to   update   and   tune   the   cost-benefit   model   accordingly   to  increase   its   reliability   and   validity.   The   model   could   also   be   developed   further   to   incorporate   AM’s  additional   benefits,   such   as   weight   and   material   reduction   through   design   for   additive  manufacturing   (DfAM). / Syftet   med   denna   förstudie   var   att   identifiera   och   utvärdera   olika   affärsmöjligheter   för   Epirocs   Parts  &   Services-division   (PSD)   gällande   användningen   av   additiv   tillverkning   (AM),   även   känd   som  3D-printning,   för   deras   reservdelar   inom   gruvindustrin.   Denna   studie   presenterar   ett  tillvägagångssätt   för   hur   reservdelar   passande   för   AM   kan   identifieras   och   visar   på   svårigheterna  med   AM.   Studien   följer   "design   research   methodology"   (DRM),   vilket   kan   översättas   till  designforsknings-metodologin,   som   är   vanligt   förekommande   vid   forskning   inom   produkt-   och  processutveckling.   Genom   intervjuer   och   litteratursökningar   tillämpades   en   "top-down"-metod.  Detta   åtföljdes   av   en   utvecklad   kostnadsnyttomodell   som   tillsammans   användes   för   att   identifiera  och   utvärdera   potentiella   reservdelar   för   AM   från   Epirocs   nuvarande   reservdelsportfölj.   Resultaten  utvärderades   som   lovande   för   flertalet   av   reservdelarna   vad   gäller   reducerad   kostnad   för  tillverkning,   inköp,   verktyg   och   minskad   ledtid,   vilket   resulterar   i   ökad   drifttid   för   kunden.   Med  minskade   ledtider   ökar   tillgängligheten   för   kunden,   som   kan   öka   Epirocs   försäljning   och  eftermarknadsintäkter   på   lång   sikt.   Det   finns   också   en   stor   potential   i   att   minska   kostnaderna   för  lagerhållning,   där   reservdelar   med   låg   efterfrågan   kan   få   sina   lager   att   reduceras   eller   elimineras  genom   att   säkra   utbudet   genom   tillverkning   vid   behov.   Även   om   många   intressanta  affärsmöjligheter   har   identifierats   och   utvärderats   har   det   uppmärksammats   att   CNC-bearbetning   i  många   fall   kan   vara   det   billigare   alternativet.   Trots   detta   är   det   värt   att   investera   i   AM   ur   en  strategisk   synvinkel   eftersom   det   ses   som   ett   verktyg   för   framtiden.   Innan   AM   kan   anammas   och  implementeras   bör   Epiroc   göra   testförsök   med   företag   som   erbjuder   AM-tjänster.   Dessa   kan  användas   för   att   uppdatera   och   justera   kostnadsnyttomodellen   i   enlighet   med   detta   för   att   öka   dess  validitet   och   reliabilitet.   Modellen   kan   också   utvecklas   vidare   för   att   införliva   AM:s   ytterligare  fördelar,   såsom   vikt-   och   materialreduktion   genom   design   för   additiv   tillverkning   (DfAM).

Massgravar : En metodstudie med utgångspunkt i osteoarkeologi och rättsmedicin. / Mass graves : A methodological study based in bioarchaeology and forensics.

Sjögren, Linda January 2021 (has links)
This essay focuses on how the osteological analysis is carried out in studies of different types of mass graves. The analysis is based on 20 studies of different types of mass graves. The 20 studies were selected because they represent analyses of various types of mass graves and because they all contain a presentation of the methods used in the examinations of the remains. Different types of archaeological mass graves are examined as well as forensically interesting ones. Similarities and differences between aims, questions asked, and methodology in studies of different types of mass graves are examined. The purpose for which the various methods are used is also investigated with the aim of seeing whether the same method can be utilized for different purposes in studies of different types of mass graves.  One conclusion reached is that a tendency can be seen that a certain set of methods is used in most studies of mass graves. Some differences can be seen depending on the main focus of the studies and the type of mass grave that is examined. The main differences can be distinguished between archaeological and forensic investigations. The two disciplines are similar in many ways but the focus in the studies and the purpose of them often differ. In forensic studies the aim is usually identification, while archaeological studies tend to have a broader focus, which is reflected in choices of methods and questions asked.  In all of the studies, largely the same kind of methods are used, however, it appears that different versions of a method can be applied. Researchers have developed various more specific versions of methods and a tendency can be seen that the different studies use different versions of the same kind of methods.  Another conclusion drawn is that although researchers state that at the moment there is no common standard for how investigations of mass graves should be carried out, it appears in this essay that a certain common structure can still be seen. Although there is no stated standard, there seems to be an unspoken one, at least when it comes to methodology in examinations of human remains from mass graves.

Arbetsmotivation : En studie om ledarskapets påverkan på generation Z:s arbetsmotivation / Work motivation : A study of the influence of leadership on generation Z:s work motivation

Schellhas, Emilia January 2020 (has links)
I denna studie fokuseras ledarskapets påverkan på generation Z:s arbetsmotivation. Denna generation börjar etablera sig på arbetsmarknaden, vilket betyder att ledarskapet inom organisationer påverkas. Därför undersöker jag i denna studie hur man som ledare kan motivera generation Z på bra vis. Med intervjuer som primärdata är syftet med studien att undersöka grunden till arbetsmotivation, både ur generation Z:s perspektiv samt ur ett ledarskapsperspektiv. Den empiriska studien kommer sedan att analyseras utifrån grundad teori, där Gioias metodologi tillämpas. Här genereras teori där även existerande teori används för att stärka, bekräfta och skapa nya hypoteser utifrån den aktuella forskningen.

Att göra demokrati : En kartläggning av forskningen om Botkyrkas demokratiarbete / Making democracy : A mapping of democracy research in Botkyrka

Hallberg, Klara January 2014 (has links)
By studying a place or a phenomena research contributes to the creation of the image of the thing that he or she studies. Also, planning is seen as a democratic tool, a way to ”make” democracy. In order to see what democratic ideals that is being express it becomes important to study the research about democracy in Botkyrka. It is from this thinking this study about democracy and research has been formed. The study is a mapping of the research about democracy work in Botkyrka between the years 1997-2014. Through explorative approach, the research has been identified and thematized. The method used is mapping with influences from qualitative content analysis and narrative approach. The research is analyzed by the theoretical concept of democracy and theories about representative-, participatory- and deliberative democracy are used. In this way the research’s story about Botkyrkas democracy work is captured. A total of 22 pieces of research projects has been identified and thematized. The thematization were based on the study's research questions and theoretical perspectives. The themes can be understood from two aspects, the first is about the research methodology and premises and the other about the content of the research. Ten themes were identified, analysed and discussed. Based on thematization the general research question about what democratic ideals the research expresses is being answered. The story of the research about the democracy work in Botkyrka contains a variety of expressions. Everything from classical democracy problems to stimulating research perspective is being processed and shifts between democratic ideals can be seen. Some research uses innovative methods and different theoretical approaches which indicates that the researchers want to explore new aspects of the concept of democracy. / Forskning bidrar till skapandet av bilden av platser och fenomen, forskaren är således medskapare av den verklighet han eller hon studerar. Samtidigt kan planering ses som ett sätt att göra demokrati, ett demokratiskt instrument. Att studera forskningen kring demokrati i Botkyrka blir därmed viktigt för att kunna se vilka demokratiska ideal denna ger uttryck för, då den påverkar hur samhället formas. Utifrån resonemanget växte denna studie om demokrati och forskning fram. Studien är en kartläggning över forskning kring Botkyrkas arbete med demokrati och delaktighet. Genom explorativ metod har forskningen identifierats och tematiserats. De metodologiska utgångspunkterna har varit i den kvalitativa innehållsanalysen, också element av narrativ metod har använts. Materialinsamlingen har genomgående präglats av det studerade objektet. Syftet med studien har varit att kartlägga forskning i Botkyrka inom ämnet demokrati och delaktighet mellan åren 1997-2014. Materialet har sedan analyserats utifrån begreppet demokrati med en fördjupning i de tre demokratiskolorna valdemokrati, deltagardemokrati och samtalsdemokrati. På så sätt fångas forskningens berättelse om Botkyrkas demokratiarbete. Sammanlagt har 22 forskningsalster identifierats och tematiserats. Tematiseringarna gjordes med utgångspunkt i studiens frågeställningar och teoretiska perspektiv. Temana kan förstås utifrån två olika aspekter, där den första handlar om forskningens metod och utgångspunkter och den andra om innehållet i forskningen. Totalt har tio teman skapats. Utifrån temana besvaras den övergripande frågeställningen om vilka demokratiska ideal forskningen ger uttryck för. Berättelsen om Botkyrkas demokratiarbete innehåller en variation av uttryck. Alltifrån klassiska demokratiproblem till utvecklande forskningsperspektiv behandlas och glidningar mellan olika demokratiska ideal kan ses. Några forskningsprojekt använder sig av nytänkande metoder och annorlunda teoretiska utgångspunkter vilket kan ses som ett tecken på att forskarna vill utforska nya aspekter av demokratin.

Regressionstestning ur agil synvinkel : En studie om testare och mjukvaruutvecklares uppfattning om regressionstestning / Regression testing through an agile point of veiw : A study about software testers and developers perception on regression testing

Vuckovic, Aljosa January 2022 (has links)
Då mjukvaruutveckling består av testning av mjukvara innebär det attmjukvarutestning ökar i takt med ny mjukvara. En typ av mjukvarutestning ärregressionstestning som innebär testning av befintlig mjukvara i syfte att säkerställaatt mjukvaran fungerar som planerat efter att ny funktionalitet tillkommer. Agilautvecklingsprocesser blir alltmer populära, dock är det brist på generell forskning sombetraktar regressionstestning ur en agil synvinkel. Denna studie ämnar undersöka hur agila mjukvaruutvecklingsteam arbetar medregressionstestning. Syftet med studien var att bidra med teoretisk kunskap kringregressionstestning ur agil kontext. För att genomföra undersökningen tillämpades enkvalitativ ansats med semi-strukturerade intervjuer. Tre testare och tre utvecklare frånett mjukvaruutvecklingsföretag intervjuades. Tematisk analys applicerades sedan tillstudiens resultat. Resultatet indikerar på att testare utgår ifrån sin domänkunskap samt kommunikationför att välja ut och avgöra omfattningen av testfall. Kommunikationen består avfunktionaliteten som tillkommer, förändringar som utvecklare har utvecklat men sominte var en del av den ursprungliga uppgiften samt potentiella riskområden.Mjukvaruutvecklare förlitar sig på befintliga tester för att säkerställa att nyfunktionalitet inte påverkar det befintliga systemet. Det innebär att för varje nyfunktionalitet som tillkommer behöver utvecklare säkerställa att tillräcklig kod täcksav relevanta enhets- och integrationstest. / Since software development consists of software testing the amount of softwaretesting increases in step with new software. One type of software testing is regressiontesting, which involves testing existing software in order to ensure that the softwareworks as planned after new functionality is added. Agile development processes arebecoming increasingly popular, however, there is a lack of general research thatconsiders regression testing from an agile point of view. This study aims to investigate how agile software development teams work withregression testing. The aim of the study was to contribute with theoretical knowledgeabout regression testing from an agile context. To carry out the survey, a qualitativeapproach was applied with semi-structured interviews. Three testers and threedevelopers from a software development company were interviewed. Thematicanalysis was applied to the results. The result indicates that testers rely on their domain knowledge and communicationto select and determine the scope of test cases. The communication consists of thefunctionality that is added, changes that developers have developed but were not partof the original task and potential risk areas. Software developers rely on existing teststo ensure that new functionality does not affect the existing system. This means thatfor every new functionality that is added, developers need to ensure that sufficientcode is covered by relevant unit and integration tests.

Existentialismen är en sociologi : en essä om sociologi i en fragmenterad samtid

Grönqvist, Simon January 2010 (has links)
<p>The purpose of this essay is to discuss the base of sociology from an existentialistic perspective. The discussion takes it's position in the debate on the crisis of sociology, and aligns with Alvin Gouldner's understanding of the crisis. Gouldner believed that the crisis of sociology was mirrored in a sociological method that failed to describe the social reality that it meant to describe; a lack in self-criticism and self-reflexivity, a lack in self-containment in relation to state interests and a lack in moral engagement. This raises a number of questions, which I discuss in the essay. What is the role of sociology in our society? How shall we form a method that responds to the social reality that we sociologists aim to describe? How can we make sociology more moral?</p><p>Existentialism offers a starting point to describe these questions. I argue that the existentialistic description of man as essence carries implications for the social science. By constituting a critique of a computable moral, existentialism points at the necessity of a standing self-criticism and dialogue. An existentialistic description of man as non-essence carries implications for the theory and method of sociology. Man's possibility of radical exceeding of himself means the impossibility to reach theories that describe reality as it is. At the same time, method and theory are necessary to create knowledge about social phenomenon. I read existentialism as an imperative for a sociology that is reflexive in the sense a) a reflexivity in relation to the basic presumptions (value philosophical and ontological) that effect our sociological examinations b) a self-reflexivity that amount to an understanding of the scientists own role relation to his study and the object being studied. Furthermore, I read existentialism as an imperative for a radicalization of dialogue as method.</p>

Presenting the Absent : An Account of Undocumentedness in Sweden

Sigvardsdotter, Erika January 2012 (has links)
This thesis provides an ethnography and critical phenomenology of undocumentedness in the Swedish context. By attending to the forces and processes that circumscribe the life-worlds of undocumented persons, as well as the phenomenology and essential experiences of their condition, a complex and multi-layered illustration of what undocumentedness is and means is successively presented. Employing a dual conceptualization of the state, as a juridico-political construct as well as a practiced and embodied set of institutions, the undocumented position emerges as a legal category defined only through omission, produced and reproduced through administrative routine and practice. The health care sector provides empirical examples of state-undocumented interaction where the physical and corporeal presence of the officially absent becomes irrefutable. This research suggests that the Swedish welfare state – universalistic, comprehensive and with digitized administrative routines – becomes a particularly austere environment in which to be undocumented. Drawing on interviews with regional and local health care administrators, NGO-clinics’ representatives and health professionals, as well as extensive participatory observation and interviews with undocumented persons, I argue that the undocumented condition is characterized by simultaneous absence and presence, and a correspondingly paradoxical spatiality. I suggest that the official absence and deportability of undocumented persons deprives them of the capacity to define space and, in an Arendtian sense, appear as themselves to others. There are, however, some opportunities for embodied political protest and dissensus. The paradoxical qualities of the absent-present condition manipulate the undocumented mode of being-in-the-world and I argue that alienation and disorientation are essential experiences of the undocumented situation.
