A key issue in sexual selection theory is how a correlation between male secondary sexual characters and male genetic quality can be maintained. The immunocompetence-handicap hypothesis proposes that testosterone-dependent male characters remain honest signals because of the immunosuppressive effect of elevated steroid hormone levels. The hypothesis requires that physiological levels of testostero

This paper demonstrates how nostalgia entices consumers to re-circulate objects rather than discard them. Through multimethod qualitative inquiry into the Danish vintage cycling community, this paper highlights how consumers’ nostalgic attachment to the biographies of old objects propels re-circulation. The analysis builds on three distinct modes of nostalgia: reluctant, progressive, and playful n

In the last column, we promised to return to one of the inevitable challenges that vibe coding leaves us with. At the AI Engineer World’s Fair 2025, OpenAI’s Sean Grove claimed that whoever writes the specification is now the programmer since AI can take it from there. Sounds amazing, but what gets lost along the way? To explore this, I’m joined by Jan-Philipp Steghöfer, a researcher at XITASO and

This Bachelor's Thesis investigates whether China’s corruption effects on trade differ from the rest of the world’s. The question is raised by the seemingly positive correlation between corruption and imports – in direct contradiction to previous research, concluding the relationship to be negative. Two Gravity Models are evaluated using Panel EGLS (Cross-section random effects) regressions o

It is generally agreed upon that social trust is strongly associated with income inequality. However, this conclusion is mainly drawn from cross-country studies, which most likely suffer from endogeneity issues due to unobserved cultural, social and political variables affecting both trust and inequality.

Language is a social act and the fact that social communities create new or change existing words that are known in daily standard language, can make the lexicon difficult to comprehend for the ones not involved. The communication that belong to a specific social group can be classified as a jargon, and in this present study we look at gaming language as an example of how social communities’ lexic

This master thesis explores commercialization of electric road systems in urban environments, using a combined methods approach, in contrast to previous studies that have focused on long haul transportation. First, through interviews and document gathering, a stakeholder map was constructed, and the incentives of the identified stakeholders were analyzed. The thesis found disagreements between the

Autonomous Agents are usually designed to work in the background and their work is mostly hidden from the user. This causes both ethical and practical problems that can be remedied by providing feedback and control to the user (Bellotti and Sellen, 1993). This thesis presents an overview study exploreing advantages and disadvantages of four visualization techniques: colouring, pictographic symbols

Gaming as a Service is not defined in existing research. The lack of a formal definition leads to an ambiguity between its function as a business model and the long-term strategy of the firm. The purpose and aim of this study is to investigate the definition of GaaS business model, distinguishing its function from the strategy. Furthermore, the key components of the model are established based on

INTRODUCTION: Mental health service users often have sensory processing difficulties hampering their ability to cope with mental health problems and occupational engagement. However, there is little knowledge of sensory processing and its relation to these factors. Hence, this current study aims to investigate sensory processing patterns in relation to coping and occupational engagement for the ta

Medellivslängden för människor runt om i världen är högre än någonsin. Äldre personer löper högre risk för att drabbas av kroniska sjukdomar, inklusive kronisk njursjukdom. Patienter med dysfunktionella njurar behöver dialys. Njurarnas huvudfunktion är att rena blodet från restprodukter och överflödigt vatten.
