I explain what exactly constrains presupposition projection in compound sentences and argue that the presuppositions that do not project are conditionalized, giving rise to inferable conditional presuppositions. I combine elements of (Gazdar in Pragmatics: implicature, presupposition, and logical form. Academic Press, New York 1979) and (van der Sandt in Context and presupposition. Croom Helm, London 1988) which, together with an additional, independently motivated assumption, make it possible to construct an analysis that makes correct predictions. The core of my proposal is as follows: When a speaker felicitously utters a compound sentence whose constituent clauses (considered in isolation) require presuppositions, the hearer will infer that the speaker presupposes those propositions, unless the sentence contains some element that makes the hearer realize that, if the speaker actually presupposed them, she would be either uninformative or inconsistent in her beliefs. In these cases, the propositions that would have been presupposed, had the clauses been uttered in isolation, will not be presupposed, i.e. the clausal presuppositions will not project. 相似文献

Purpose
Questionable research or reporting practices (QRPs) contribute to a growing concern regarding the credibility of research in the organizational sciences and related fields. Such practices include design, analytic, or reporting practices that may introduce biased evidence, which can have harmful implications for evidence-based practice, theory development, and perceptions of the rigor of science.Design/Methodology/Approach
To assess the extent to which QRPs are actually a concern, we conducted a systematic review to consider the evidence on QRPs. Using a triangulation approach (e.g., by reviewing data from observations, sensitivity analyses, and surveys), we identified the good, the bad, and the ugly.Findings
Of the 64 studies that fit our criteria, 6 appeared to find little to no evidence of engagement in QRPs and the other 58 found more severe evidence (91 %).Implications
Drawing upon the findings, we provide recommendations for future research related to publication practices and academic training.Originality/value
We report findings from studies that suggest that QRPs are not a problem, that QRPs are used at a suboptimal rate, and that QRPs present a threat to the viability of organizational science research.994.
Purpose
An item-sort task is a common method to reduce over-representative item lists during the scale-creation process. The current article delineates the limitations and misapplications of the accepted statistical significance formula for item-sort tasks and proposes a new statistical significance formula with greater utility across a wider range of item-sort tasks.Design
First, a simulation study compares the two formulas in an array of conditions that vary on sample size and number of assignment choices. Second, an empirical study compares the results of three separate item-sort tasks across the two formulas for statistical significance.Findings
In the empirical study, the proposed formula produces more correct retention decisions than the existing formula across all three item-sort tasks. In the simulation study, the proposed formula is more appropriate than the existing formula under most conditions. The two formulas function identically in item-sort tasks with only two assignment choices.Implications
Researchers could obtain erroneous results when misapplying the existing item-sort task statistical significance formula to cases with more than two assignment choices. The proposed formula corrects this limitation, ultimately providing accurate results more often than the existing formula. Applying the proposed formula could help future research and practice throughout the scale development process.Originality
Despite widespread use, few attempts have been made to improve scale-creation pretest methods, particularly item-sort tasks. The current study demonstrates that even conventional statistical methods are susceptible to misuse and misapplication, and future research could benefit from the reexamination of other common methods.995.

Proactive and reactive aggression represent distinct functions of aggression that are associated with different risk factors, including individual and contextual characteristics. However, more research evaluating the interactive effects of risk factors is needed. The current study evaluated whether corporal punishment moderated the influence of neighborhood problems and anger coping on proactive and reactive aggression in a child psychiatric inpatient sample of 6 to 13 year olds (n?=?151). Findings were compared across child- and caregiver-reports of aggression. Consistent with expectations, anger coping was more strongly associated with reactive aggression than proactive aggression across informants. In contrast, perceived neighborhood problems were only associated with child-reports of proactive aggression, with corporal punishment moderating this association. Specifically, the association between neighborhood problems and proactive aggression was only evident at high levels of corporal punishment. Treatment implications and future directions are discussed. 相似文献

Exposure to violence (ETV) has emerged as a key and stable predictor of violent offending. However, not all youth offenders who experience ETV go on to chronic violent offending. Consequently, it is possible that individual differences, such as psychopathic traits, may be an important factor in the link between ETV and violent offending. These traits are associated with exposure to violence and, separately, to violent offending. The present study used data from Pathways to Desistance, a multisite, longitudinal study of serious juvenile offenders (N = 1170, Meanage = 16.05, SD = 1.16) to explore these relationships, simultaneously. First, autoregressive cross-lagged path models were used to examine the longitudinal bivariate relations among violent offending, ETV, and psychopathic traits. Second, latent class growth analysis was used to determine trajectories ETV. And third, the mediating influence of psychopathic traits was examined. Results indicated that ETV predicted later engagement in violence, but there was some degree of reciprocity between ETV and violence over time. Additionally, respondents with stable high or increasing trajectories of ETV reported more instances of violent offending. Finally, psychopathic traits mediated the relationship between ETV and violent offending. Together these findings support the notion that individuals with psychopathic traits perceive and internalize their environment differently than others and that this difference guides their own violent offending. Given the importance of psychopathic traits for understanding the influence of ETV on violent offending, prevention and intervention strategies must be developed that take into account both individual differences and environmental factors. 相似文献

This study set out to investigate parental attitudes toward entrepreneurship education as evaluative directing components of social representations. A nationwide sample of parents (N = 625) was asked to indicate their opinions on a set of statements about entrepreneurship education. The parents’ attitudinal orientation suggested that they would rather avoid entrepreneurship education than approach it. Additionally, parental evaluations contained indecision and polarised opinions, and most parents saw it as unlikely or were unsure whether their children would become entrepreneurs. Parental attitudes correlated with the established representations of education and subsequent policy stands, suggesting that entrepreneurship education has been made familiar by anchoring attitudes in the field of educational debates. It was suggested that current trends in educational policy and work life may stimulate the formation of polemical social representations pertaining to entrepreneurship education. 相似文献

Several factors related to fetal risk render it more or less acceptable in justifying constraints on the behavior of pregnant women. Risk is an unavoidable part of pregnancy and childbirth, one that women must balance against other vital personal and family interests. Two particular issues relate to the fairness of claims that pregnant women are never entitled to put their fetuses at risk: relative risks and relatives' risks. The former have been used—often spuriously—to advance arguments against activities, such as home birth, that may incur risk; the latter implicate the nature of relationships in determining the acceptability of coercing or precluding activities. Motivated reasoning by clinicians and judges leads to inaccurate risk assessments, and judgments based on false claims to objectivity. Such judgments undermine the moral and legal standing of pregnant women and do not advance the interests of fetuses, pregnant women, families, or states. 相似文献

Pathological gambling is characterized by excessive gambling behavior which influences the life and well-being of a person in a dysfunctional way. It often leads to severe consequences in social and family life, career and material matters. This can also include illegal acts. In the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) excessive gambling was classified under impulse-control disorders but was renamed as gambling disorder (GD) and reclassified under the category “substance-related and addictive disorders” in DSM-5, due to parallels to substance use disorders in the clinical characteristics as well as genetic and neurobiological factors. In Germany, approximately 0.5?% of the adult population suffer from GD. Especially gambling machines are associated with an increased risk of gambling-related problems. Common comorbidities are substance-related and affective disorders. The most important risk factors are young age, male gender, a history of migration, gambling-related problems in the family, unemployment, a low educational level and low household income. Delinquent behavior was not considered to be a sufficiently discriminative factor for GD, although there is a correlation between delinquency and gambling behavior. In addition, those GD subjects who show delinquent behavior also show a specific risk profile. Thus, mental health professionals should be aware of possible psychosocial consequences in GD, such as illegal acts, and this should be addressed in the effective treatment strategies, such as cognitive behavioral therapy. Moreover, it is necessary to improve the access routes for affected people into healthcare system in order to ensure early detection and treatment of the disease. 相似文献
