Covid-19 pandemin innebar en stor förändring för anställda runt om i hela världen. För att minska smittspridningen övergick en mängd platsbundna arbeten över till arbete på distans där hushållet plötsligt förvandlades till arbetsplats. Syftet med denna kvalitativa studie var att undersöka åtta medarbetares upplevelse av balansen mellan privat- och arbetsliv vid den tvingande omställningen till arbete på distans. I studien genomfördes semistrukturerade intervjuer. Det transkriberade materialet analyserades med en induktiv tematisk analys som resulterade i följande huvudteman som är namngivna enligt följande (underteman är namngivna inom parentes): Gränsdragning och segmentering vid tvingande distansarbete (arbetsplats i hushållet, strategier för att skilja mellan privat- och arbetsliv samt privat- och yrkesroll), flexibla arbetstider (avbrott i arbetet) och sociala aspekter (stöd). Studien påvisade att informanterna hade implementerat olika strategier och strukturer för att uppnå en gränsdragning mellan privat- och arbetsliv. Vissa genom fokus på miljön runt omkring och andra genom noggranna tidsbestämmelser. Överlag har informanterna haft en positiv inställning till arbete på distans med undantag för negativa upplevelser gällande sociala aspekter. / The Covid-19 pandemic had a big impact on employees around the world. To reduce the spread of infection, several on-site works was transferred to remote work, where the household was suddenly transformed into a workplace. The purpose of this qualitative study was to examine eight employees' experience of the balance between private and working life during the urgent transition to work from home. The transcribed material was analyzed with an inductive thematic analysis that resulted in main themes named as follows (subthemes are named in parentheses): Demarcation and segmentation in compulsory remote work (workplace at home, strategies for distinguishing between private- and working life and private- and professional role), flexible working hours (breaks at work) and social aspects (support). The study showed that the informants implemented different strategies and structures to achieve a demarcation between private and working life. Some through more focus on the environment. And others through precise working time regulations. Overall, the informants have had a positive attitude towards working at a distance, apart from negative experiences regarding social aspects.

Impacts of human agency have become a major driver in the Earth System, with magnitude comparable to that of natural occurring global processes. Several earth system processes are under substantial pressure.  These human induced pressures are likely to increase, potentially leading to undesirable changes at planetary scale. In that context, the Planetary Boundaries concept has been put forward aiming at defining a “safe operating space” for future endurance of humanity: relevant processes were identified with associated boundaries that, if respected, would avoid large-scale or irreversible change. The present study explores how human driven resource use relates to the Planetary Boundaries concept, through a water-food-energy-climate nexus perspective. It aims at identifying alternatives for the consideration of biophysical constraints in ways resources are modelled, and it presents an account of the current elements that hinder the integration of new constraints. The study found that existing Integrated Assessment Models and conceptual models for exploring Climate-Land-Energy-Water Strategies present important contributions, but further integration is necessary. Furthermore, decision-making support tools in these models were designed to assess mitigation options for climate, but cannot yet be used for multi-goal or multi-constraints studies. Scenario studies were found to be an important and yet underappreciated tool for such integration. The study identified novel techniques for scenario construction that could be applied in this context – they can allow the construction of sets of scenarios to bridge across scales or to connect separate modelling communities. The study suggests that for bridging the current gaps that exist between concepts it is necessary to develop an active interface across research communities involved in global change research, integrated assessment and resource modelling communities. These interfaces need to allow the co-development of concepts, the sharing of data and the confrontation of different perspectives on the shared challenge of exploring potential pathways for sustainability. / Planetary Boundaries research initiative

This short communication is devoted to the room temperature processes of diffusion and redistribution of dissolved carbon atoms in martensite to the nanosegregation regions at dislocations and grain boundaries. It is related to the DF7 contribution of M. Lavrskyi et al. on the carbon kinetics in martensite [1] and to the DF7 contribution of Yu. Nechaev on the compound-like nanosegregation at dislocations and grain boundaries in metallic materials.

In the past decade, the counseling profession has begun to recognize the impact of vicarious trauma on counselors who provide services to individuals who have experienced trauma. The constructivist self-development theory asserts that interpersonal frameworks can determine healthy versus unhealthy coping styles and impact a counselor's susceptibility to vicarious trauma. Researchers have explored vicarious trauma in a number of professions such as mental health counseling and social work however they have not examined potential risk factors specific to school counseling. The purpose of this correlational study was to investigate variables associated with vicarious trauma in school counselors. The research focused on the relationship between vicarious trauma and the level of exposure to student trauma, history of trauma in the counselor's personal life, self-other differentiation, level of school, and amount of trauma education. An electronic questionnaire was sent to 654 school counselors in four school districts in Virginia and was returned by 217. The survey included the Vicarious Trauma Scale, Self-Other Differentiation Scale, Adverse Childhood Experiences Inventory-Revised, and demographic survey. Data analysis conducted using multiple regression revealed a significant negative relationship between scores on the Self-Other Differentiation Scale and scores on the Vicarious Trauma Scale indicating counselors with less emotional differentiation from clients are more likely to have higher levels of vicarious trauma. Results of the study may be used to reduce the risk of vicarious trauma in school counselors so they can continue to support students who have been exposed to trauma.

Orientador: Eudes Borges de Araújo / Resumo: Nos últimos anos, grande atenção tem sido dada ao desenvolvimento de células solares com o iodeto de chumbo e metilamônio (MAPbI3) em virtude de suas excelentes propriedades fotovoltaicas. Apesar de altas eficiências de conversão de energia terem sido atingidas com essas células, a síntese desse material e algumas de suas características elétricas permanecem em estudo. No presente trabalho, mostrou-se que a síntese desse material na forma de filmes finos via spin-coating deve ser executada preferencialmente com soluções precursoras de dimetilsulfóxido depositadas sobre platina, com maiores tempos e temperaturas de secagem e aumento da taxa de remoção do solvente. Por sua vez, pastilhas de MAPbI3 tiveram condições ótimas de sinterização a 120°C por 2h. O material foi caracterizado em termos de suas propriedades elétricas por meio da espectroscopia de impedância, com tensões de frequências na faixa de 300 Hz a 1 MHz e temperaturas no intervalo entre 100 e 430K, tendo sido observada uma histerese entre o aquecimento e o resfriamento nos comportamentos da permissividade elétrica, impedância, módulo elétrico e condutividade elétrica, que se mostraram sensíveis à temperatura e às frequências da tensão de teste. Ainda, foram observadas alterações dessas propriedades elétricas associadas às transições de fase, cujas temperaturas em que ocorrem se mostraram independentes da frequência da tensão. A fim de separar os efeitos diferenciados dos grãos e contornos de grão nas propriedades e...

Although high energy conversion efficiencies have been achieved with these cells, the synthesis of this material and some of its electrical characteristics remain under study. In the present research, it was shown that the synthesis of this material in the form of spin-coating thin films should be performed preferably with dimethylsulfoxide precursor solutions deposited over platinum surfaces, with higher drying times and temperatures and increasing the solvent removal rate. In turn, MAPbI3 pellets had optimum sintering conditions at 120°C for 2h. The material was characterized in terms of it’s electrical properties by impedance spectroscopy, with frequency voltages in the range of 300 Hz to 1 MHz and temperatures in the range 100 to 430K, and a hysteresis between heating and cooling was observed on permissivity, impedance, electrical modulus and conductivity behaviors, which were sensitive to temperature and applied voltage frequencies. In addition, changes in these electrical properties associated with phase transitions were observed, whose temperatures at which they occurred were independent of the voltage frequency. In order to separate the differentiated effects of grains and grain boundaries on the electrical properties of MAPbI3, an equivalent circuit was proposed that was efficient to describe the exper...

The Doughnut Economy integrates social and environmental sustainability into one holistic model. As sustainability becomes more relevant for multinational corporations, it is crucial to explore the possibilities of the Doughnut Economy as a tool for enhancing and visualising corporate sustainability efforts. Therefore, this study examines how multinational corporations' sustainability strategies align with the Doughnut Economy model and explores potential challenges and stakeholder benefits of alignment. Moreover, this interpretive study adopts an inductive approach, employing an exploratory and explanatory case study to contribute to existing theory and practice. Gathering qualitative data through semi-structured interviews with sustainability managers at Husqvarna Group, complemented by the company's 2022 sustainability report as secondary data. Next, thematic analysis was used to analyse the empirical findings, providing a comprehensive understanding of patterns and themes. Overall this study concludes that strategic alignment with the Doughnut Economy enables multinational corporations to enhance sustainability efforts and enables stakeholder benefits. Additionally, there are challenges of alignment due to the Doughnut Economy model’s complexity and limited stakeholder knowledge, however, investments in education and stakeholder engagement can address these challenges. By embracing the suggested strategies and overcoming identified obstacles, multinational corporations can strengthen their alignment with the Doughnut Economy, contributing to a sustainable future.

Romantic, dyadic relationships arise, in part, from communication, disclosure, and boundaries. Information communication technology (ICT), such as smartphones, has rapidly integrated into our personal lives and affected relationship initiation, maintenance, and dissolution. To this point, models attempting to account for this emerging dynamic center on past theories about relationships. However, counselors and researchers would benefit from understanding contemporary couple dynamics that reflect the ICT-mediated changes to coupling that occurred during the last decade. To address this need, researchers conducted a grounded theory study to explore relationship dynamics, mediated by ICT, based on stories and descriptions provided by 16 participants. Findings showed technology influenced relationships in four domains: access, intimacy, boundaries, and presence.
