An Exploratory Study of Perceived Career Change and Job Attitudes Among Job Changers

The study examined the effects of job change characteristics on perceived career change and attitudes toward the new job. The job change characteristics examined were content of change, magnitude of change, direction of change, volitionality of job choice, and duration of the unemployment period between the two jobs. The subjects were 222 university educated men and women. It was found that perceived career change was firmly related to job change characteristics reflecting both "internal" and "external" career perspectives. After controlling for the direction of change, the magnitude of change had a negative impact on satisfaction with the new job, while the volitionality of job choice and the duration of unemployment were positively associated with job satisfaction. Contrary to expectation, the volitionality of job choice and the duration of unemployment did not increase the commitment to continue in the new job.     

Satisfiability Decay along Conjunctions of Pseudo-Random Clauses

k-SAT is a fundamental constraint satisfaction problem. It involvesS(m), the satisfaction set of the conjunction of m clauses,each clause a disjunction of k literals. The problem has manytheoretical, algorithmic and practical aspects. When the clauses are chosen at random it is anticipated (butnot fully proven) that, as the density parameter m/n (n thenumber of variables) grows, the transition of S(m) to beingempty, is abrupt: It has a "sharp threshold", with probability1 – o(1). In this article we replace the random ensemble analysis by apseudo-random one: Derive the decay rule for individual sequencesof clauses, subject to combinatorial conditions, which in turnhold with probability 1 – o(1). This is carried out under the big relaxation that k is not constantbut k = log n , or even r log log n . Then the decay of S isslow, "near-perfect" (like a radioactive decay), which entailssharp thresholds for the transition-time of S below any givenlevel, down to S = .     

Leadership and Social Identification in Military Units: Direct and Indirect Relationships1

This study examines some antecedents and consequences of social identification in military units. Data were collected from 2 samples in each unit: staff members and soldiers. It was found that identification with the unit was related to 3 categories of leader behavior: an emphasis on collective identity, an emphasis on shared values, and inclusive behaviors. Some of the effects of leader behaviors on members' social identification were mediated by their effects on unit culture. Some of the effects of leader behaviors on the social identification of more distant subordinates (soldiers) were mediated by their effects on the social identification of closer subordinates (staff members). Differential effects of leader behaviors on the 2 levels of subordinates were also discovered.     

Conflict, Identity, and Tolerance: Israel in the Al-Aqsa Intifada

This paper explores the impact of the Al-Aqsa Intifada on tolerance orientations of the Israeli Jewish public. We rely upon five surveys carried out between January 2000 and June 2002 to study in a real-life setting the amount and nature of change in political tolerance due to the conflict and the mechanisms behind it. Building on theory and research on intergroup relations in social psychology and political tolerance in political science, we focus upon threat and ingroup identification as the two primary factors in the social psychological processes resulting from conflict and leading to intolerance. We set the trends and explore mediation and interaction processes in the impact of this round of conflict on political tolerance.     

Some antecedents of work-nonwork conflict

This study examined the relationships of three aspects of work schedules—shiftwork, length of workday, and work during weekends and holidays—with the perceived interrole conflict between work and nonwork. Personal background variables and characteristics of the work role itself were hypothesized to be directly related to the level of conflict and, in addition, to moderate the work schedules-conflict relationships. Subjects were 286 hotel employees. As expected all three aspects of work schedules were related to the level of felt work-nonwork conflict. Personal background variables were not related in any way to the level of conflict. Job satisfaction and organizational role conflict were found to be directly related to the level of interrole conflict and, in addition, to moderate the work schedules-conflict relationships. Together, job-related variables and the interactions among them accounted for over 50% of the variance in work-nonwork conflict.     

Adding fuel to fire: the impact of followers' arousal on ratings of charisma

The authors conducted an experimental laboratory study and a longitudinal field study to investigate the impact of followers' arousal on ratings of charisma. Both studies examined 2 contrasting hypotheses: (a) the misattribution hypothesis, which posits a direct effect of arousal, and (b) the response-facilitation hypothesis, which posits an interactive effect of arousal and leaders' charismatic appeal on ratings of charisma. The overall results from both studies provide support for the response-facilitation hypothesis. In addition, the authors tested the hypothesis that arousal effects are limited to ratings of charisma. As expected, ratings of transactional leadership, in contrast with ratings of charisma, were not influenced by followers' arousal states. The authors discuss the implications of these results and offer suggestions for future research.     

The two faces of transformational leadership: empowerment and dependency

Followers' identification with the leader and the organizational unit, dependence on the leader, and empowerment by the leader are often attributed to transformational leadership in organizations. However, these hypothesized outcomes have received very little attention in empirical studies. Using a sample of 888 bank employees working under 76 branch manages, the authors tested the relationships between transformational leadership and these outcomes. They found that transformational leadership was positively related to both followers' dependence and their empowerment and that personal identification mediated the relationship between transformational leadership and followers' dependence on the leader, whereas social identification mediated the relationship between transformational leadership and followers' empowerment. The authors discuss the implications of these findings to both theory and practice.     

Attribution of Influence and Charisma to the Leader: The Romance of Leadership Revisited1

This study examined the impact of performance outcomes, leadership type, leader behaviors, and observers' general belief in the importance of leadership on attributions of influence and charisma to a leader. Subjects (N= 549) read 24 versions of an organizational vignette representing all possible combinations of two performance levels, two leadership roles, and six leader behavior conditions, and were asked to evaluate the leader's level of causal influence and charisma. Results supported and extended Meindl's (1990) claim that observers' tendency to romanticize the role of a specific leader is affected by the group performance outcomes and by observers' general beliefs in the importance of leadership in organizations. The results further suggested that more influence may be attributed to a prototypical leadership role than to a less prototypical role. However, information about leader behaviors did not affect the attributions of influence and charisma to the leader. These results are discussed with reference to Conger and Kanungo's (1987) attributional theory of charismatic leadership and leadership categorization theory (Lord, 1985).
