Putting PhD students front and center: an empirical analysis using the Effort-Reward Imbalance Model
IntroductionA doctorate is associated with numerous challenges for many PhD students, including financial insecurities, little support from supervisors, and time pressure. The present study explores well-being of PhD students via the Effort-Reward Imbalance (ERI) model as well as the potential protective factor resilience.MethodA web-based questionnaire survey was conducted among 1,275 PhD students from Germany. Data was collected at two measurement points over a six-week follow-up period.ResultsAs hypothesized, overcommitment was found to mediate the relationship between ERI and perceived stress while no mediation effect was found for work engagement. Resilience strengthened the relationship between ERI and overcommitment, especially for an increasing unfavorable ERI, and counterintuitively did not act as a protective factor.DiscussionTheoretical and practical implications are discussed, providing a deeper understanding on the ERI model and the negative coping pattern overcommitment in the context of PhD students
Multidisciplinary perspectives on Artificial Intelligence and the law
This open access book presents an interdisciplinary, multi-authored, edited collection of chapters on Artificial Intelligence (‘AI’) and the Law. AI technology has come to play a central role in the modern data economy. Through a combination of increased computing power, the growing availability of data and the advancement of algorithms, AI has now become an umbrella term for some of the most transformational technological breakthroughs of this age. The importance of AI stems from both the opportunities that it offers and the challenges that it entails. While AI applications hold the promise of economic growth and efficiency gains, they also create significant risks and uncertainty. The potential and perils of AI have thus come to dominate modern discussions of technology and ethics – and although AI was initially allowed to largely develop without guidelines or rules, few would deny that the law is set to play a fundamental role in shaping the future of AI. As the debate over AI is far from over, the need for rigorous analysis has never been greater. This book thus brings together contributors from different fields and backgrounds to explore how the law might provide answers to some of the most pressing questions raised by AI. An outcome of the Católica Research Centre for the Future of Law and its interdisciplinary working group on Law and Artificial Intelligence, it includes contributions by leading scholars in the fields of technology, ethics and the law.info:eu-repo/semantics/publishedVersio
The Pragmatic Development of a Carbon Management Framework for UK SMEs
The UK's commitment to net-zero emissions by 2050 is challenged by critics citing current government strategies as inadequate, marked by a lack of concrete action and aspirational guidelines. Notably, businesses, including small and medium-sized enterprises (SMEs) which constitute about half of all business emissions, are pivotal to this goal. Yet, existing policies and standards often neglect the significant role of SMEs, who face barriers such as limited knowledge and resources in implementing carbon management practices.
This thesis explores the development of a novel carbon management framework specifically designed for medium-sized organisations in the UK to address these problems. The research adopts a practical approach through collaboration with an industry partner, facilitating a case study for real-world application.
Adopting a mixed-methods research design grounded in pragmatism, the study commenced with a qualitative study in the form of a focus group. This exploratory phase, critical for understanding SME challenges, yielded rich data revealing key management themes in strategy, energy, and data. The framework design was supported by a materiality assessment and input from key stakeholders on three major iterations. The final framework comprises three phases: establishing a baseline carbon footprint, creating a carbon reduction plan, and strategically implementing this plan. The validation process, conducted at Knowsley Safari, successfully tested the initial two phases but faced constraints in fully assessing the third phase due to time limitations.
While the research achieved its primary aim of developing a novel carbon management framework for SMEs, it encountered limitations, notably in time and the generalisability of findings due to reliance on a single case study. Future research could test the framework across diverse SME settings to establish its broader applicability and effectiveness in aiding the UK's net-zero emission goals
Safe passage for attachment systems:Can attachment security at international schools be measured, and is it at risk?
Relocations challenge attachment networks. Regardless of whether a person moves or is moved away from, relocation produces separation and loss. When such losses are repeatedly experienced without being adequately processed, a defensive shutting down of the attachment system could result, particularly when such experiences occur during or across the developmental years. At schools with substantial turnover, this possibility could be shaping youth in ways that compromise attachment security and young people’s willingness or ability to develop and maintain deep long-term relationships. Given the well-documented associations between attachment security, social support, and long-term physical and mental health, the hypothesis that mobility could erode attachment and relational health warrants exploration. International schools are logical settings to test such a hypothesis, given their frequently high turnover without confounding factors (e.g. war trauma or refugee experiences). In addition, repeated experiences of separation and loss in international school settings would seem likely to create mental associations for the young people involved regarding how they and others tend to respond to such situations in such settings, raising the possibility that people at such schools, or even the school itself, could collectively be represented as an attachment figure. Questions like these have received scant attention in the literature. They warrant consideration because of their potential to shape young people’s most general convictions regarding attachment, which could, in turn, have implications for young people’s ability to experience meaning in their lives
Deterrence Gap: Avoiding War in the Taiwan Strait
The likelihood China will attack Taiwan in the next decade is high and will continue to be so, unless Taipei and Washington take urgent steps to restore deterrence across the Taiwan Strait. This monograph introduces the concept of interlocking deterrents, explains why deterrents lose their potency with the passage of time, and provides concrete recommendations for how Taiwan, the United States, and other regional powers can develop multiple, interlocking deterrents that will ensure Taiwanese security in the short and longer terms. By joining deterrence theory with an empirical analysis of Taiwanese, Chinese, and US policies, the monograph provides US military and policy practitioners new insights into ways to deter the People’s Republic of China from invading Taiwan without relying exclusively on the threat of great-power war.https://press.armywarcollege.edu/monographs/1960/thumbnail.jp
Exploring determinants of antimicrobial prescribing behaviour using the theoretical domains framework.
Few theoretically-based, qualitative studies have explored determinants of antimicrobial prescribing behaviour in hospitals. Understanding these can promote successful development and implementation of behaviour change interventions (BCIs). To use the Theoretical Domains Framework (TDF) to explore determinants of clinicians' antimicrobial prescribing behaviour, identifying barriers (i.e., impediments) and facilitators to appropriate antimicrobial practice. Semi-structured interviews with purposively-sampled doctors and pharmacists with a wide range of specialties and expertise in Hamad Medical Corporation hospitals in Qatar. Interviews based on previous quantitative research and the TDF were audio-recorded, transcribed and independently analysed by two researchers using the TDF as an initial coding framework. Data saturation was achieved after interviewing eight doctors and eight pharmacists. Inter-related determinants of antimicrobial prescribing behaviour linked to ten TDF domains were identified as barriers and facilitators that may contribute to inappropriate or appropriate antimicrobial prescribing. The main barriers identified were around hospital guidelines and electronic system deficiencies (environmental context and resources); knowledge gaps relating to guidelines and appropriate prescribing (knowledge); restricted roles/responsibilities of microbiologists and pharmacists (professional role and identity); challenging antimicrobial prescribing decisions (memory, attention and decision processes); and professional hierarchies and poor multidisciplinary teamworking (social influences). Key facilitators included guidelines compliance (goals and intentions), and participants’ beliefs about the consequences of appropriate or inappropriate prescribing. Further education and training, and some changes to guidelines including their accessibility were also considered essential. Antimicrobial prescribing behaviour in hospitals is a complex process influenced by a broad range of determinants including specific barriers and facilitators. The in-depth understanding of this complexity provided by this work may support the development of an effective BCI to promote appropriate antimicrobial stewardship
We, the City
Given their unchecked neoliberal restructuring, Berlin and Istanbul have been exposed to various forms of political polarisation and social injustice over the last decade. As a result, the struggle for affordable housing, access to public space, fair working conditions, ecological justice and the right to different ways of life has intensified. Various forms of resistance "from below" have challenged the relationship between local governments and social movements, questioning where and how the city's political problems arise. In a mixture of dialogues, essays and critical reflections, this book explores the ways in which residents of Berlin and Istanbul experience, express and resist the physical, political and normative reorganisation of their cities. It poses the question: Who is the We in We, the City
Autobidders with Budget and ROI Constraints: Efficiency, Regret, and Pacing Dynamics
We study a game between autobidding algorithms that compete in an online
advertising platform. Each autobidder is tasked with maximizing its
advertiser's total value over multiple rounds of a repeated auction, subject to
budget and/or return-on-investment constraints. We propose a gradient-based
learning algorithm that is guaranteed to satisfy all constraints and achieves
vanishing individual regret. Our algorithm uses only bandit feedback and can be
used with the first- or second-price auction, as well as with any
"intermediate" auction format. Our main result is that when these autobidders
play against each other, the resulting expected liquid welfare over all rounds
is at least half of the expected optimal liquid welfare achieved by any
allocation. This holds whether or not the bidding dynamics converges to an
equilibrium and regardless of the correlation structure between advertiser
valuations
“Who asked for this?”: authenticity and race-centered corporate social responsibility
The purpose of this study is to conceptualize and operationalize race-centered CSR, a combination of corporate social responsibility and corporate social advocacy concerned with repairing racial relationships and inequities, and test perceptions of authenticity of race-centered CSA. Authenticity in CSR and CSA has assumed a universal consumer, however authenticity, as a cultural construct, suggests that social identity can motivate how groups of people come to understand it. As corporate social responsibility efforts increasingly center race, race itself becomes a new measure by which to understand how those efforts are seen as authentic. The study surveyed 586 Blacks and non-Blacks using a modified version of Alhouti, Johonson, and Holloway’s (2016) consumer perceptions of CSR authenticity scale, Sellers et al.’s (1997) Multidimensional Inventory of Black Identity (MIBI) scale, and adapted measures using the concepts of reconciliation and cultural commodification to conceptualize race-centered CSR and perceptions of authenticity of race-centered CSR. Two new scales were developed to measure perceptions of commodification and reconciliatory discourse as antecedents for race-centered CSR activities. Findings of this study suggests that there are universal understandings of authenticity in race-centered and of what commodification of Black culture is in the context of race-centered CSR. More importantly, the recognition of commodification of Black culture is related to perceptions of authenticity of race-centered CSR. In addition, there are subtle differences in demographic drivers for Blacks and non-blacks, particularly political ideology (conservative Blacks vs. liberal whites) and education, age, and marital status of Black respondents in perceptions of authenticity of race-centered CSR. This study contributes to The study contributes to the body of literature on critical approaches to corporate social responsibility
