This study aims to analyze factors and individual characteristics that affect the outcomes:work-life balance, work engagement and sense of coherence for white-collar workers whenworking remotely. In today’s society where technology is constantly evolving, hybrid and remote work optionsare becoming more common. Research has shown that work-life balance, work engagement,and sense of coherence affect employee well-being and organizational performance. Theresearch on the extent to which remote work can contribute to sustainable work andemployee well-being is mixed, and most of the research on remote work has been conductedeither before or during the COVID-19 pandemic. Further post-pandemic research cancontribute to more sustainable work and society as a whole. To analyze what factors affect the outcomes in a remote work setting, a mixed-methodapproach was used to gain a comprehensive understanding, including a quantitative and aqualitative study. The quantitative method included bivariate correlation tests, multiple linearregression and group difference testing on cross-sectional survey data collected from twolarge Swedish companies. The qualitative method included six interviews with experiencedwhite-collar workers, which helped us interpret the findings and gain a more in depthunderstanding of quantitative results. To analyze the study findings the theoretical model ofhuman, technology, and organization (HTO) was applied. The quantitative study showed that social support from superiors, remote leadership quality,functionality of digital management systems and digital learning climate were identified asfactors that were associated with work-life balance, work engagement and sense ofcoherence. However, digital resources and social support from superiors were found to beinfluencing work engagement and sense of coherence to a greater extent. For work-lifebalance, social support from superiors and remote leadership quality was found to besignificant. The qualitative study showed that the interviewees' perception of work-lifebalance, work engagement, and sense of coherence was affected by flexible workingarrangements, functionality and use of digital tools, social interaction, collaboration,communication, inspirational relationships at the workplace, supportive colleagues, andsupportive and responsive superiors. Better understanding of what factors affect employees'personal and working life when working remotely can help organizations to promoteoccupational well-being and performance, which can contribute to more sustainable work. / Denna studie syftar till att analysera faktorer och individuella egenskaper som påverkarutfallen: balans mellan arbete och privatliv, arbetsengagemang och känsla av sammanhangför tjänstemän som arbetar på distans. I dagens samhälle där tekniken ständigt utvecklas, blir hybrid- och distansarbeten alltvanligare. Forskning har visat att balans mellan arbete och privatliv, arbetsengagemang ochkänsla av sammanhang påverkar medarbetarnas välbefinnande och organisatorisk prestation.Forskningen om i vilken utsträckning distansarbete kan bidra till hållbart arbete ochmedarbetarnas välbefinnande är blandad, och det mesta av forskningen om distansarbete harbedrivits antingen före eller under COVID-19-pandemin. Ytterligare postpandemiskforskning kan bidra till ett mer hållbart arbete och samhället. För att analysera vilka faktorer som påverkar utfallen i distansarbete användes en blandadmetod för att få en övergripande förståelse, inklusive en kvantitativ och en kvalitativ studie.Den kvantitativa metoden inkluderade bivariata korrelationstester, multipel linjär regressionoch tester av gruppskillnader. Tvärsnittsdata samlades in från två stora svenska företaggenom en enkät. Den kvalitativa metoden inkluderade sex intervjuer med erfarna tjänstemänoch hjälpte oss att tolka utfall och få en mer djupgående förståelse av kvantitativatestresultat. För att analysera studiens resultat användes den teoretiska modellen förmänniska, teknologi och organisation (MTO). Den kvantitativa studien visade att socialt stöd från överordnade, ledarskapskvalitet pådistans, funktionalitet av digitala ledningssystem och digitalt lärandeklimat identifieradessom faktorer som korrelerade med utfallen. Digitala resurser och socialt stöd frånöverordnade visade sig dock ha en större förknippning med faktorerna som påverkararbetsengagemang och känsla av sammanhang. För balans mellan arbete och privatliv varsocialt stöd från överordnade och ledarskapskvalitet på distans betydande. Den kvalitativastudien visade att intervjupersonernas uppfattning om balans mellan arbete och privatliv,arbetsengagemang och känsla av sammanhang påverkades av flexibla arbetsarrangemang,funktionalitet och användning av digitala verktyg, social interaktion, samarbete,kommunikation, inspirerande relationer på arbetsplatsen, stödjande kollegor, samt stödjandeoch lyhörda överordnade. Bättre förståelse för vilka faktorer som påverkar anställdaspersonliga liv och arbetsliv när de arbetar på distans kan hjälpa organisationer att främjayrkesmässigt välbefinnande och prestation, vilket kan bidra till ett mer hållbart arbete.

Abstract State-Corporate Crime in Swedish – A prestudy in definitions and opportunity structures The purpose of this study was to, through Swedish cases of state-corporate crime, raise the concept in a Swedish context and study whether there were specific opportunity structures in Swedish conditions and analyze this trough criminological theory. The data collection method consisted of a media and literature review, where the selection was based on the concept of state-corporate crime. The data was then studied through a crime script analysis, and finally analyzed in a comparative case study. The Swedish cases that were found were: the Bofors affairs, the Saudi agreement, the JAS affairs and the Telia affairs. These constituted examples of both State initiated corporate crime and State facilitated corporate crime and turned out to have similar opportunity structures. Which consisted of pressure for profit, criminal tools in the form of bribes and middlemen, and of neutralization techniques. The result match Cressey's fraud triangle theory of pressure, opportunity, and rationalization. / Sammanfattning State-Corporate Crime på svenska – En förstudie i definitioner och tillfällesstrukturer Syftet med denna studie var att genom svenska fall av state-corporate crime dels lyfta begreppet i en svensk kontext, dels undersöka om specifika tillfällesstrukturer gjorde sig gällande i svenska förhållanden samt analysera dessa mot kriminologisk teori. Datainsamlingsmetoden utgjorde en media- och litteraturgenomgång där urvalet grundade sig i begreppsapparaten state-corporate crime. Det empiriska materialet undersöktes sedan genom en skriptanalys, för att avslutningsvis analyseras i en jämförande fallstudie. De kända svenska fall som påträffades var Boforsaffärerna, Saudiavtalet, JAS-affärerna samt Telia-affärerna. Dessa utgjorde exempel på både State initiated corporate crime och State facilitated corporate crime och visade sig ha liknande mönster av tillfällesstrukturer. Tillfällesstrukturerna bestod övergripande i en press om vinst, brottsliga verktyg i form av mutor och mellanhänder samt av neutraliseringstekniker. Vilket är förenligt med Cresseys teori om fraud triangle.

Tax crimes, money laundering and other financial crimes threaten the strategic, political and economic interests of developed and developing countries. The problems encountered by the researcher, is the broad and vague meaning of financial crime compounded by the confusing and ill-considered use of the term by law- and policymakers, politicians, government agencies, agency officials and practitioners weakening effective communication about the phenomenon. The literature shows that given the complexity and multi-faceted nature of financial crime, combating financial crime in all its facets cannot be undertaken by investigative agencies acting in isolation. This study was undertaken with the aim to describe and systematically categorise financial crime and evaluate the prospect of using a Whole-of-Government approach as a framework to harness the capacity of the existing government agencies to combat financial crime more effectively. The research was underpinned by a pragmatic paradigm allowing the researcher to apply a qualitative research methodology using an exploratory and evaluation research design. A detailed review of the literature available nationally and internationally was conducted to establish a conceptual and practical understanding of the issues under investigation. An interview schedule with predetermined questions was developed, pre-tested and administered to participants who are active practitioners involved in combating financial crime in the primary government agencies responsible for combating financial crime based on a purposive sample. The data obtained from the literature and participants were analysed, interpreted and thematically listed according to the frequency with the aim of identifying and comparing similarities and differences between the data. The data was used to develop a system to categorise financial crime systematically based on descriptors used to describe the meaning and application of the term financial crime and to propose practical methods practises and models to combat financial crime more effectively. This research indicates that financial crime can be systematically categorised according to descriptors of the unlawful conduct and that the whole of government approach is a viable approach to combat financial crime more effectively according to the available models for arranging Whole-of-Government work. / Police Science / D.Litt. et Phil.

Dans ce travail, nous définissons des objets composés de disques complexes marqués reliés entre eux par des segments de droite munis d’une longueur. Nous construisons deux séries d’espaces de module de ces objets appelés clus- ters, une qui sera dite non symétrique, la version ⊗, et l’autre qui est dite symétrique, la version •. Cette construction permet des choix de perturba- tions pour deux versions correspondantes des trajectoires de Floer introduites par Cornea et Lalonde ([CL]). Ces choix devraient fournir une nouvelle option pour la description géométrique des structures A∞ et L∞ obstruées étudiées par Fukaya, Oh, Ohta et Ono ([FOOO2],[FOOO]) et Cho ([Cho]). Dans le cas où L ⊂ (M, ω) est une sous-variété lagrangienne Pin± mono- tone avec nombre de Maslov ≥ 2, nous définissons une structure d’algèbre A∞ sur les points critiques d’une fonction de Morse générique sur L. Cette struc- ture est présentée comme une extension du complexe des perles de Oh ([Oh]) muni de son produit quantique, plus récemment étudié par Biran et Cornea ([BC]). Plus généralement, nous décrivons une version géométrique d’une catégorie de Fukaya avec seul objet L qui se veut alternative à la description (relative) hamiltonienne de Seidel ([Sei]). Nous vérifions la fonctorialité de notre construction en définissant des espaces de module de clusters occultés qui servent d’espaces sources pour des morphismes de comparaison. / We define objects made of marked complex disks connected by metric line seg- ments and construct two sequences of moduli spaces of these objects, referred as the ⊗ version (nonsymmetric) and the • version (symmetric). This allows choices of coherent perturbations over the corresponding versions of the Floer trajectories proposed by Cornea and Lalonde ([CL]). These perturbations are intended to lead to an alternative geometric description of the (obstructed) A∞ and L∞ structures studied by Fukaya, Oh, Ohta and Ono ([FOOO2],[FOOO]) and Cho ([Cho]). Given a Pin± monotone lagrangian submanifold L ⊂ (M, ω) with mini- mal Maslov number ≥ 2, we define an A∞ -algebra structure from the critical points of a generic Morse function on L. We express this structure as a cochain complex extending the pearl complex introduced by Oh ([Oh]) and further ex- plicited by Biran and Cornea ([BC]), equipped with its quantum product. This could also be seen as an alternative geometric description of a Fukaya cate- gory of (M, ω) with L as its only object, a hamiltonian relative version appear- ing in [Sei]. Using spaces of quilted clusters, we verify, using more general quilted cluster spaces, that this defines a functor from a homotopy category of Pin± monotone lagrangian submanifolds hL mono,± (M, ω) to the homotopy category of cochain complexes hK(Λ-mod) where Λ is an appropriate Novikov ring.

Les effets délétères sur la santé de certaines expositions professionnelles, prises indépendamment, ont été observés dans un large nombre d’études. Pourtant, la prévalence et l'impact de multi-exposition ou co-exposition à des diverses nuisances ont plus rarement été explorée, malgré le caractère ubiquitaire de nombreuses nuisances. Par conséquent, l’étude de multi-exposition/co-exposition dans le cadre professionnel est considérée comme un enjeu majeur de la recherche épidémiologique en santé au travail. Une revue systématique de la littérature concernant le secteur de l’agriculture a été réalisé en s'appuyant sur le titre, le résumé, et le texte intégral des 36.404 articles originaux grâce à 5 bases de données reconnues et 2 sources de données nord-américaines complémentaires. Les résultats des 15 articles inclus suggèrent que l’exposition aux multiples chimiques est significativement associée au risque de maladies respiratoires, de cancers, de dommages sur l’ADN et les cytogénétiques. L’exposition aux multiples physiques a été associée à une augmentation du risque de perte d'audition, tandis que la co-exposition aux facteurs physiques et biomécaniques a été associée à un risque accru de troubles musculo-squelettiques. Aucune étude n'a exploré la co-exposition professionnelle à des facteurs chimiques et physiques, ainsi qu'à la co-exposition professionnelle à des facteurs chimiques et biomécaniques. Les résultats de cette revue de la littérature indiquent la nécessité l’évaluer la prévalence de l’exposition professionnel à des multiples nuisances en France. Les multiple/co-expositions aux agents neurotoxiques chimiques(ANCs) et aux contraintes physiques intenses (CPIs) ont ainsi été analysées chez 5587 hommes ouvriers français des secteurs de l'agriculture, de l’industrie manufacturière, et de la construction à partir de l’enquête nationale transversale SUMER 2010. Environ 6% des ouvriers étaient co-exposés aux ANCs et CPIs dans les trois secteurs étudiés (p = 0,29). La multi-exposition aux CPIs était plus nettement plus fréquente (35%, p <0,001) que la multi-exposition aux ANCs (2%, p <0,001) chez les hommes de trois secteurs. Ces recherches mettent en évidence la nécessité de conduire davantage d’études liées à multi-exposition/coexposition professionnelle. Elles seront essentielles pour améliorer la sécurité au travail et permettre la surveillance et la prévention risques et des maladies professionnelles. / A wide range of studies has demonstrated the relationships between diverse types of occupational exposures,taken independently, and adverse health outcomes. Yet, the prevalence and impact of multiple occupational exposures or co-exposures have rarely been explored despite the ubiquity of numerous hazards. Therefore, multiple occupational exposures/co-exposures and their impact on health are considered as a major challenge of epidemiologic research inthe occupational health and safety area. A systematic review concerning the agriculture sector was carried out based on the titles, abstracts and fulltexts screening of 36,404 initial articles from 5 well-known databases and 2 North American complementary sources. The findings from the 15 papers finally included suggested that multiple chemical exposures were significantly associated with an increased risk of respiratory diseases, cancers, DNA and cytogenetic damages. Multiple physical exposures were shown to increase the risk of hearing loss while co-exposures to physical and biomechanical hazardswere associated with an increased risk of musculoskeletal disorders. However, no studies included in the systematic review explored either occupational co-exposures to both physical and chemical factors or occupational co-exposures to biomechanical and chemical factors.The results described in the systematic review raised the necessity to conduct further studies multipleoccupational exposures and co-exposures among workers. Therefore, multiple occupational exposures and coexposures’ prevalences to chemical neurotoxic agents (CNAs) and intense physical constraints (IPCs) were examined among 5,587 French male blue-collar workers (BCWs) in the agriculture, manufacturing, and construction sectors based on the cross-sectional and national SUMER 2010 survey. About 6% of male BCWs were co-exposed to IPCs andCNAs in these three sectors (p=0.29). Multiple exposures to IPCs was predominantly observed (35%, p <0.001), while multiple exposures to CNAs was much lower (2%, p <0.001) among male BCWs in three sectors.The findings highlight the necessity to carry out further studies on multiple occupational exposures/coexposures to diverse hazards and their impact on workers’ health. These further researches are required to improve occupational safety and the efficiency of health care surveillance and occupational disease prevention.
