Studia Logica - In this paper we provide a detailed proof-theoretical analysis of a natural deduction system for classical propositional logic that (i) represents classical proofs in a more natural...     

The Role of Apparent Constraints in Normative Reasoning: a Methodological Statement and Application to Global Justice

The assumptions that are made about the features of the world that are relatively changeable by agents and those that are not (constraints) play a central role in determining normative conclusions. In this way, normative reasoning is deeply dependent on accounts of the empirical world. Successful normative reasoning must avoid the naturalization of constraints and seek to attribute correctly to agents what is and is not in their power to change. Recent discourse on global justice has often come to unjustified conclusions about agents obligations due to a narrow view of what is changeable and by whom.I would like to thank for their helpful comments Christian Barry, Rudiger Bittner, Darrel Moellendorf and Thomas Pogge.     

Up-regulating positive emotions in everyday life: Strategies, individual differences, and associations with positive emotion and well-being

This research aimed to identify strategies people use to up-regulate positive emotions, and examine associations with personality, emotion regulation, and trait and state positive experience. In Study 1, participants reported use of 75 regulation strategies and trait emotional experience. Principal component analysis revealed three strategy domains: engagement (socializing, savoring), betterment (goal pursuit, personal growth), and indulgence (substance use, fantasy). In Study 2, participants reported state-level regulation and emotional experience. Engagement correlated with greater state and trait positive emotion, and overall greater well-being. Betterment correlated with less state, but greater trait, positive emotion. Indulgence correlated with greater state, but less trait positive emotion and overall lower well-being. This research suggests trade-offs between short-term and long-term emotional consequences of different strategies.     

An exploration of the Indian mindset

Eight hundred and twenty-nine adults, drawn from 12 locations in all four parts of India, participated in a study that explored the joint effects of Indians’ discrepant mindset, context sensitivity, and quality of environment on their modes of behavior. Respondents also predicted how a person is likely to change his behavior when the conditions in which he works change from disabling to enabling. The findings showed that the two most dominant modes of behavior-self-serving calculative and achieving high positive goal — coexisted, but were differently caused. Context sensitivity facilitated both modes of behavior; but adequate infrastructure and friendly and helpful people in the neighborhood encouraged only achieving high positive goal behavior. On the contrary, duplicity in professing desirable but acting under realistic compulsions, poor quality of environment, and low levels of development were conducive to self-serving calculative behavior. As a situation changed from disabling to enabling, a person was likely to shift towards more positive behavior.     

The prevalence,risk factors and outcomes of workplace bullying among junior doctors: a systematic review

ABSTRACT

Junior doctors’ exposure to bullying may impact their training and compromise quality healthcare, yet little is known in relation to its predictors and effects. The aim of this paper is to assess the prevalence, factors and outcomes of workplace bullying among junior doctors. Literature search was performed to identify all primary studies examining workplace bullying among junior doctors using the following electronic databases: Medline, Scopus, Web of Science, PsycINFO and Cochrane Library. A total of 18 articles were included, reporting on a total of 9,597 junior doctors. The quality of evidence can be rated as moderate according to the Newcastle Ottawa Scale. From the review, a wide range (30–95%) of bullying prevalence, significant differences in bullying rates according to gender, age, height, ethnicity and subspecialty, and significant associations between bullying and mental strain, job dissatisfaction, burnout, and increased accidents at work were observed. Concurrently, heterogeneity in the terms and methodologies used to examine workplace bullying as well as definitional issues in relation to the persistency of negative interactions were noted. Evidence suggests that workplace bullying is a serious occupational hazard for junior doctors, and more research is warranted to better understand this phenomenon and address its definitional and methodological issues.     

Risk communication of terrorist acts, natural disasters, and criminal violence: comparing the processes of understanding and responding

Risk communication is an important vehicle for the scientific understanding of the perception of and response to various kinds of threats. The present study provides apparently the first empirical attempt to compare perceptions, decision‐making, and anticipated action in response to threats of three kinds: natural disaster, violent crime, and terrorism. A total of 258 college undergraduates were surveyed using a vignette‐based, 2 × 2 × 3 between‐subjects design that systematically manipulated threat imminence (high vs. low), risk level (high vs. low), and nature of the threat (natural disaster vs. crime vs. terrorism). There were substantial differences in participants' perceptions and reported actions in response to natural disaster, relative to the other domains of risk, under conditions of high risk. The risk of natural disaster was more likely to lead participants to report that they would change their daily activities and to relocate. It was also more likely than terrorism to lead to action securing the home. It appears that the mechanisms for perception, decision‐making, and action in response to threats cannot be generalized in a straightforward way across these domains of threat.

Attachment, Marital Satisfaction, and Divorce During the First Fifteen Years of Parenthood

This study examines two overlapping longitudinal samples of U.S. couples with children, covering a period of 15 years after the first child's birth. The first sample extended from the pregnancy with a first child until that child was 5.5 years old; the second from ages 4.5 to 14.5. Growth curve analyses revealed that marital satisfaction declined over 15 years for both husbands and wives. Attachment security measured in the second sample was associated with greater marital satisfaction, but did not buffer against declines in marital satisfaction over time. Husbands' lower initial level of marital satisfaction measured around the first child's transition to school was the only significant predictor of marital dissolution. The discussion emphasizes theoretical and practical implications of these findings.
