ObjectivesLittle is known about the mechanisms that might mediate the relationship between transformational leadership behaviors and follower outcomes in the sporting domain. The purpose of this study was to examine whether intrateam communication mediated the effects of transformational leadership behaviors on task cohesion.Design/MethodsA cross-sectional study of university level ultimate frisbee players (N = 199). Participants completed a measure assessing their perceptions of their captain's transformational leadership behaviors. Post-competition, participants completed measures assessing perceptions of intrateam communication and task cohesion within their own team.ResultsMultilevel analyses revealed intrateam communication to partially mediate the relationships between two of the transformational leadership behaviors and task cohesion.ConclusionsIntrateam communication is seen to be a mechanism that explains the relationship between transformational leadership and task cohesion. Overall, the results support and add to the range of positive effects associated with transformational leadership in sport, and are suggestive of interventions that may raise levels of team cohesion. 相似文献

Basic fact acquisition is an important component for developing higher-order math skills. However, getting students with a
history of academic noncompliance to engage in activities related to skills acquisition can be difficult. Prior research demonstrates
that engagement increases when nonpreferred activities are preceded by a series of brief activities with a high probability
of completion. This technique, called high-p task/request sequences, was not fully explored within the context of skill acquisition. The purpose of this study was to
examine the effects of adding high-p sequences to explicit instruction on the math fact acquisition of three elementary-age students in a learning support classroom.
Results showed no differences in fact acquisition between explicit instruction and explicit instruction with an added high-p component. However, the high-p sessions took nearly twice as long to complete when compared to explicit instruction alone. Implications for instructional
efficiency and limitations of the high-p procedures for acquisition tasks are discussed. 相似文献

This paper draws together two strands in the debate over the existence of mathematical objects. The first strand concerns the notion of extra‐mathematical explanation: the explanation of physical facts, in part, by facts about mathematical objects. The second strand concerns the access problem for platonism: the problem of how to account for knowledge of mathematical objects. I argue for the following conditional: if there are extra‐mathematical explanations, then the core thesis of the access problem is false. This has implications for nominalists and platonists alike. Platonists can make a case for epistemic access to mathematical objects by providing evidence in favour of the existence of extra‐mathematical explanations. Nominalists, by contrast, can use the access problem to cast doubt on the idea that mathematical objects play a substantive role in scientific explanation. 1 相似文献

This paper reviews the current debate between differentiation and attachment in treating couples through exploring the tenets of crucible therapy (Schnarch, 1991) and emotionally focused couple therapy (Johnson, 2004). We provide a review of the two theories—as well as the two “pure form” example models—and explore the debate in light of the integrative movement in couple and family therapy (Lebow, 2014). We also examine points of convergence of the two theories and models, and provide clinicians and researchers with an enhanced understanding of their divergent positions. Both differentiation and attachment are developmental theories that highlight the human experience of balancing individuality and connection in adulthood. The two models converge in terms of metaconcepts that pervade their respective theories and approach. Both models capitalize on the depth and importance of the therapeutic relationship, and provide rich case conceptualization and processes of therapy. However, they substantially differ in terms of how they view the fundamental aspects of adult development, have vastly divergent approaches to how a therapist intervenes in the room, and different ideas of how a healthy couple should function. In light of the deep polarization of the two models, points of integration—particularly between the broader theories of attachment and differentiation—are offered for therapists to consider. 相似文献

Four studies were conducted with two primary objectives: (a) to conceptualize and measure mental toughness from a behavioral perspective and (b) to apply relevant personality theory to the examination of between‐person differences in mentally tough behavior. Studies 1 (N = 305 participants from a range of different sports) and 2 (N = 110 high‐level cricketers) focused on the development of an informant‐rated mental toughness questionnaire that assessed individual differences in ability to maintain or enhance performance under pressure from a wide range of stressors. Studies 3 (N = 214) and 4 (N = 196) examined the relationship between reinforcement sensitivities and mentally tough behavior in high‐level cricketers. The highest levels of mental toughness reported by coaches occurred when cricketers were sensitive to punishment and insensitive to reward. Study 4 suggested that such players are predisposed to identify threatening stimuli early, which gives them the best possible opportunity to prepare an effective response to the pressurized environments they encounter. The findings show that high‐level cricketers who are punishment sensitive, but not reward sensitive, detect threat early and can maintain goal‐directed behavior under pressure from a range of different stressors. 相似文献

In this paper we consider the implicational fragment of Abelian logic \({{{\sf A}_{\rightarrow}}}\) . We show that although the Abelian groups provide an semantics for the set of theorems of \({{{\sf A}_{\rightarrow}}}\) they do not for the associated consequence relation. We then show that the consequence relation is not algebraizable in the sense of Blok and Pigozzi (Mem Am Math Soc 77, 1989). In the second part of the paper, we investigate an extension of \({{{\sf A}_{\rightarrow}}}\) in the same language and having the same set of theorems and show that this new consequence relation is algebraizable with the Abelian groups as its equivalent algebraic semantics. Finally, we show that although \({{{\sf A}_{\rightarrow}}}\) is not algebraizable, it is order-algebraizable in the sense of Raftery (Ann Pure Appl Log 164:251–283, 2013). 相似文献

Communicators have at their disposal an ever‐increasing variety of modalities by which to transmit messages. Do the prominent norms attached to different communication modalities contain information in and of themselves? The present investigation considers this question through the lens of text messages and emails, hypothesized to confer different normative information about urgency. Text messages (vs. emails)—or any communication inferred by receivers to have been sent with greater urgency—cause the content of those messages to seem, in the eyes of receivers, closer in time (Study 1), closer in space (Study 2), and more likely to occur (Study 3). Moderation and mediation analyses confirm the role of urgency underlying the relationship between modality and distance. We provide evidence for these effects in a series of laboratory studies together with a field study in which real text messages and emails impact not only inferred distance but also a behavior deriving therefrom. Theoretical and practical implications highlight the importance, for both researchers and practitioners, of understanding how the medium of communication can shape interpretation of the message. 相似文献
