Testing Differential Mediation Effects of Sub-dimensions of Political Skills in Linking Proactive Personality to Employee Performance

Purpose  

The purpose of this research was to examine the mediating roles of political skill dimensions (i.e., networking ability, interpersonal influence, social astuteness, and apparent sincerity) in linking employees’ proactive personality and supervisor-rated in-role performance and altruism.     

The development of relational competence among young high-risk fathers across the transition to parenthood

This study examined relationship factors associated with paternal functioning among young, high-risk fathers, with an emphasis on the role of a young mother's relational competence on her partner's paternal functioning. Participants included 60 young fathers and their coparenting partners, who were identified before childbirth and followed over 2 years. Fathers were identified as being at high risk for paternal failure based on a history of school dropout, psychopathology, and/or serial fatherhood. It was hypothesized that young men who were more relationally competent before childbirth would function more adequately as fathers, despite their high-risk status. Based on principles of family systems theory, it was also predicted that young men with more relationally competent partners would become more relationally competent, and therefore learn to function more positively as fathers. Relational competence was assessed using interview data collected before and 2 years post child birth, and coded with the Relational Competence Index. Paternal functioning was based on a composite score consisting of self-reported and observed parenting. Path analysis indicated that (1) high-risk fathers with relationally competent partners had higher relational competence scores over time, and (2) higher relational competence scores were associated with more positive paternal functioning scores.     

Types of semantic category and stimulus modality in procedural learning: implications for models of semantic memory

The present work attempts to determine whether procedural learning of a semantic categorisation task is influenced by the type of semantic category of the stimuli (biological and non-biological elements). It is also an attempt to determine the effect of the stimulus presentation modality on the categorisation task. A semantic categorisation task (4 series of 40 stimuli) was administered to 256 participants (128 classifying pictures, and 128 classifying words). Biological categories were responded to faster than non-biological ones although there were no significant differences between the interaction of the category type and the stimulus presentation modality. Reaction times progressively decreased with practice. However, the initial differences disappeared when subjects were trained. The way that current models account for these investigation findings is discussed. In addition, it is suggested that there is an attentional bias in favor of biological elements, which disappears when presumably less relevant elements become more relevant as a function of the task characteristics.     

Is Mere True Belief Knowledge?

Crispin Sartwell ingeniously defends the provocative thesis that mere true belief suffices for knowledge. In doing so, he challenges one of the most deeply entrenched epistemological tenets, namely that knowledge must be more than mere true belief. Particularly interesting is the way he defends his thesis by appealing to considerations adduced by such prominent epistemologists as William Alston, Laurence BonJour, Alvin Goldman and Paul Moser, each of whom denies that knowledge is merely true belief. In this paper, I argue that the case Sartwell presents for his thesis fails. However, by examining why it fails, we may derive at least four important epistemological lessons: (1) being justified does not entail being able to give a justification; (2) we should distinguish between epistemic justification conceived of as intrinsically conducive to truth and conceived of as extrinsically conducive to truth; (3) we should distinguish between epistemic justification conceived of as an essential criterion of knowledge and conceived of as an accidental criterion of knowledge; and (4) epistemologists need to specify how the telos of inquiry involves more than the acquisition of (merely) true beliefs.Socrates: Then tell me: what definition can we give with the least risk of contradicting ourselves?Theaetetus: The one we tried before, Socrates. I have nothing else to suggest.Socrates: What was that?Theaetetus: That true belief is knowledge. Surely there can at least be no mistake in believing what is true and the consequences are always satisfactory.Theaetetus 200d–e

Biased extensive measurement: The homogeneous case

In the homogeneous case of one type of objects, we prove the existence of an additive scale unique up to a positive scaling transformation without transitivity of indifference and with a property of homothetic invariance weaker than monotonicity. The representation, which is a particular case of a semiorder representation, reveals a unique positive factor α?1 that biases extensive structures and explains departures from these standard axioms of extensive measurement (α=1). We interpret α as characterizing the qualitative influence of the underlying measurement process and we show that it induces a proportional indifference threshold.     

Sales profession and professionals in the age of digitization and artificial intelligence technologies: concepts,priorities, and questions

Recognizing the rapid advances in sales digitization and artificial intelligence technologies, we develop concepts, priorities, and questions to help guide future research and practice in the field of personal selling and sales management. Our analysis reveals that the influence of sales digitalization technologies, which include digitization and artificial intelligence, is likely to be more significant and more far reaching than previous sales technologies. To organize our analysis of this influence, we discuss the opportunities and threats that sales digitalization technologies pose for (a) the sales profession in terms of its contribution to creating value for customers, organizations, and society and (b) sales professionals, in terms of both employees in organizations and individuals as self, seeking growth, fulfillment, and status in the functions they serve and roles they live. We summarize our discussion by detailing specific research priorities and questions that warrant further study and development by researchers and practitioners alike.     

Goldman On Knowledge As True Belief

Alvin Goldman contends that, in addition to the familiar sense or use of the term “knowledge” according to which knowledge is at least true justified belief, there is a weaker yet strict sense or use of the term “knowledge” according to which knowledge amounts to nothing more than information-possession or mere true belief. In this paper, I argue that Goldman has failed to show that there is such a weaker sense, and that, even if he had shown this, he has not shown that this putative weaker sense is a strict one by his own criterion for strictness.     

Influence of education on the pattern of cognitive deterioration in AD patients: the cognitive reserve hypothesis

The cognitive reserve hypothesis proposes that a high educational level could delay the clinical expression of Alzheimer's disease (AD) although neuropathologic changes develop in the brain. Therefore, some studies have reported that when the clinical signs of the disease emerge, high-educated patients may decline more rapidly than low-educated patients because the neuropathology is more advanced. However, these studies have only investigated the decline of global cognition or an isolated cognitive process. To study the differential deterioration pattern of several cognitive processes according to education, the performance of 20 AD patients with a high educational level and a low educational level were compared with the performance of 20 control subjects on a neuropsychological battery. The results showed that cognitive deterioration of AD patients is different according to education, although the global performance was similar in AD patients. The high-educated patients exhibited greater impairment of abstract thinking whereas the low-educated patients showed greater impairment of memory and attentional function. This confirms that some cognitive processes, such as abstract thinking, decline more rapidly in high-educated patients whereas others seem to evolve more slowly if compared to low-educated patients. In this latter case, high-educated patients may still benefit from cognitive reserve after the diagnosis of the dementia.
