It is shown how results of Prokhovnik on the number of pattern variants that may be formed byk markers on a square network ofm
2 positions may be derived more simply by means of a combinatorial theorem of Pólya's, which may also be used to solve systematically many other problems of this type. 相似文献

The objective of this study was to observe how the digits of the hand adjust to varying location of the center of mass (CoM) above or below the grasp and rotational inertia (RI) of a handheld object. Such manipulations do not immediately affect the equilibrium equations while stability control is affected. Participants were instructed to hold a handle, instrumented with 5 force-torque transducers and a 3-D rotational tilt sensor, while either the location of the CoM or the RI values were adjusted. On the whole, people use 2 mechanisms to adjust to the changed stability requirements; they increase the grip force and redistribute the total moment between the normal and tangential forces offsetting internal torques. The increase in grip force, an internal force, and offsetting internal torques allows for increases in joint and hand rotational apparent stiffness while not creating external forces-torques that would unbalance the equations of equilibrium. 相似文献

A five‐year research project of seminary students from various cultural backgrounds revealed that the slight majority of contemporary seminary students studied are oral learners. Oral learners learn best and have their lives most transformed when professors utilize oral teaching and assessment methods. After explaining several preferences of oral learners, suggestions for effective teaching are provided in this article in order to improve both teaching and assessment of oral learners. Applications are provided for face‐to‐face and online learning contexts. 相似文献

A previous study has shown that greater cardiac vagal tone, reflecting effective self-regulatory capacity, was correlated with superior visual discrimination of fearful faces at high spatial frequency Park et al. (Biological Psychology 90:171?C178, 2012b). The present study investigated whether individual differences in cardiac vagal tone (indexed by heart rate variability) were associated with different event-related brain potentials (ERPs) in response to fearful and neutral faces. Thirty-six healthy participants discriminated the emotion of fearful and neutral faces at broad, high, and low spatial frequencies, while ERPs were recorded. Participants with low resting heart rate variability??characterized by poor functioning of regulatory systems??exhibited significantly greater N200 activity in response to fearful faces at low spatial frequency and greater LPP responses to neutral faces at high spatial frequency. Source analyses??estimated by standardized low-resolution brain electromagnetic tomography (sLORETA)??tended to show that participants with low resting heart rate variability exhibited increased source activity in visual areas, such as the cuneus and the middle occipital gyrus, as compared with participants with high resting heart rate variability. The hyperactive neural activity associated with low cardiac vagal tone may account for hypervigilant response patterns and emotional dysregulation, which heightens the risk of developing physical and emotional problems. 相似文献

The purpose of this study is to examine how employees’ impression management motive influences their voice by considering dispositional and situational variables. Drawing on the theory of self‐motive, we hypothesized that voice would be more positively related to impression management motive than prosocial motive. In addition, based on the interactional approach of motive and trait and trait activation theory, we hypothesized that the relationship between impression management motive and voice would be moderated by self‐monitoring, self‐efficacy, and voice instrumentality. Using a sample of 307 supervisor–subordinate dyads from South Korea, we found that, although prosocial motive had a positive influence on voice, impression management motive had a stronger influence on voice than prosocial motive. We also found that the positive influence of impression management motive on voice was stronger for employees with high levels of self‐monitoring, self‐efficacy, and voice instrumentality. This study helps verify the boundary conditions as to when impression management motive is strongly related to voice. In addition, this study will provide theoretical clues for resolving the inconsistent findings on the relationship between impression management motive and voice. 相似文献

We examined how subordinates’ cognition- and affect-based trust in supervisors influences their feedback-seeking behavior (FSB) by considering the different cost/value perception of FSB and goal orientation (i.e., learning and performance goal orientations). Using data from 194 supervisor-subordinate dyads in South Korea, we conducted multiple regression analyses to test our hypotheses. The results showed that, whereas subordinates’ cognition-based trust in supervisors positively influenced their FSB through increasing the perceived value of feedback received from supervisors, their affect-based trust in supervisors positively influenced their FSB through decreasing the perceived value of FSB. Additionally, we found that, when subordinates had high levels of learning goal orientation, the increasing influence of cognition-based trust on the value of feedback was stronger; in contrast, when subordinates had low levels of performance goal orientation, the decreasing influence of affect-based trust on the cost of FSB was stronger. The theoretical and practical implications, limitations, and suggestions for future research were discussed. 相似文献

Philosophers commonly say that beliefs come in degrees (or that beliefs are graded or that there are partial beliefs). Drawing from the literature, I make precise three arguments for this claim: an argument from degrees of confidence, an argument from degrees of firmness, and an argument from natural language. I show that they all fail. I also advance three arguments that beliefs do not come in degrees: an argument from natural language, an argument from intuition, and an argument from the metaphysics of degrees. On the basis of these arguments, I conclude that beliefs do not come in degrees. 相似文献

I present a puzzle about belief and credence, which takes the form of three independently supported views that are mutually inconsistent. The first is the view that S has a modal belief that p (e.g., S believes that probably-p) if and only if S has a corresponding credence that p. The second is the view that S believes that p only if S has some credence that p. The third is the view that, possibly, S believes that p without a modal belief that p. [Word Count: 85] 相似文献

Prior research indicates that student aggression against teachers is widespread, and it has negative impacts on victimized teachers’ emotional and physical well-being and job performance. However, little is known about the relationship between the recency and duration of victimization and teachers’ thoughts about quitting the teaching profession and related job dissatisfaction and disconnectedness to school. Analyses of data from a longitudinal study of 1,236 US teachers fills these gaps. The study found that many teachers experienced theft/vandalism and sexual harassment victimization that was limited to just 1 year. In contrast, sizeable proportions of teachers experienced verbal abuse and nonphysical contact aggression that occurred over 2 years. Multiple regression analyses showed that teachers who reported recent or multiyear victimization had lower levels of connectedness to school, less job satisfaction, and more thoughts about ending their teaching careers. These results may indicate that unless victimization recurs, negative effects of victimization are contemporaneous and are less likely to persist. Additional research is needed to examine victimization over longer than 2 years, investigate the effects of the frequency of different types of aggression against teachers, and identify school policies and interventions that weaken the connection of victimization to negative outcomes. 相似文献
