Women and Leadership: A Developmental Paradox?

In this article, the author explores the nature of leadership from a gendered perspective, specifically addressing leadership challenges for women. Leadership challenges, gender stereotypes, and definitions of leadership are discussed. Recommendations for professional redefinition of leadership within the counseling profession and strategies for successful negotiation of leadership roles are provided.     

Reasoning about XML with temporal logics and automata

We show that problems arising in static analysis of XML specifications and transformations can be dealt with using techniques similar to those developed for static analysis of programs. Many properties of interest in the XML context are related to navigation, and can be formulated in temporal logics for trees. We choose a logic that admits a simple single-exponential translation into unranked tree automata, in the spirit of the classical LTL-to-Büchi automata translation. Automata arising from this translation have a number of additional properties; in particular, they are convenient for reasoning about unary node-selecting queries, which are important in the XML context. We give two applications of such reasoning: one deals with a classical XML problem of reasoning about navigation in the presence of schemas, and the other relates to verifying security properties of XML views.     

The dark side of visual awareness in sport: Inattentional blindness in a real-world basketball task

Most research in the field of decision making in sports has focused on the bright side of visual attention and has not taken the dark side of visual awareness into account. Understanding the costs of such inattention should be complementary to the study of how attention facilitates perception. In the present study, we provide evidence for the existence of inattentional blindness (IB) in a real-world basketball setting among adults (Experiment 1). In Experiment 2, we found that players with hardly any basketball experience were more likely to experience IB in a real-world basketball setting, as compared with experienced athletes. Improving the ecological validity of the setting by enhancing the perception-action coupling (Experiment 3) and increasing task difficulty (Experiment 4) did not appear to affect the occurrence of IB among experienced athletes. IB can be considered a limitation of the visual system, but it also highlights a critical aspect of visual processing, which allows us to remain focused on the important aspects of the world. But as is shown in the present experiments, it is possible to induce an attentional set—for example, by sport-specific instructions—that leads to players’ missing important game-relevant information.     

Social and Personal Factors as Predictors of Earthquake Preparation: The Role of Support Provision,Network Discussion,Negative Affect,Age, and Education1

Panel data collected in 1991 as part of the University of Southern California Longitudinal Study of Generations (LSOG) were used to predict reported preparation activities prior to and in response to the 1994 Northridge, California, earthquake. In late 1994 and early 1995, 163 panelists (representing 107 multigenerational families) were interviewed by phone about their earthquake experiences. The best 1991 predictor of pre‐quake preparation was the extent of instrumental support respondents provided to network members. Earthquake preparation activities undertaken after the quake were associated with the amount and cost of damage experienced during the quake, 1991 neuroticism scores, age (inversely), and having preparedness encouraged by multiple network sources. The results highlight the importance of social roles (e.g., support provision) and discussion by informal network sources in the adoption of public health and safety messages.     

SIMPLIFYING HEURISTICS VERSUS CAREFUL THINKING: SCIENTIFIC ANALYSIS OF MILLENNIAL SPIRITUAL ISSUES

There is ample evidence that humans (and other primates) possess a knowledge instinct—a biologically driven impulse to make coherent sense of the world at the highest level possible. Yet behavioral decision‐making data suggest a contrary biological drive to minimize cognitive effort by solving problems using simplifying heuristics. Individuals differ, and the same person varies over time, in the strength of the knowledge instinct. Neuroimaging studies suggest which brain regions might mediate the balance between knowledge expansion and heuristic simplification. One region implicated in primary emotional experience is more activated in individuals who use primitive heuristics, whereas two areas of the cortex are more activated in individuals with a strong knowledge drive: one region implicated in detecting risk or conflict and another implicated in generating creative ideas. Knowledge maximization and effort minimization are both evolutionary adaptations, and both are valuable in different contexts. Effort minimization helps us make minor and routine decisions efficiently, whereas knowledge maximization connects us to the beautiful, to the sublime, and to our highest aspirations. We relate the opposition between the knowledge instinct and heuristics to the biblical story of the fall, and argue that the causal scientific worldview is mathematically equivalent to teleological arguments from final causes. Elements of a scientific program are formulated to address unresolved issues.     

Prefrontal Cortex,Emotion, and Approach/Withdrawal Motivation

This article provides a selective review of the literature and current theories regarding the role of prefrontal cortex, along with some other critical brain regions, in emotion and motivation. Seemingly contradictory findings have often appeared in this literature. Research attempting to resolve these contradictions has been the basis of new areas of growth and has led to more sophisticated understandings of emotional and motivational processes as well as neural networks associated with these processes. Progress has, in part, depended on methodological advances that allow for increased resolution in brain imaging. A number of issues are currently in play, among them the role of prefrontal cortex in emotional or motivational processes. This debate fosters research that will likely lead to further refinement of conceptualizations of emotion, motivation, and the neural processes associated with them.     

Distributed skill functions and the meshing of knowledge structures

The scope of knowledge space theory was extended by bringing into the picture the underlying skills and capabilities that are relevant to solving the problems in a knowledge domain. A major challenge to this approach comes from the need to aggregate distributed information on (partially) overlapping domains and skill sets. The notion of a distributed skill function is introduced for formalizing the integration of several skill functions that represent the assignment of skills to problems. It is shown that their consistency is captured by the meshability of the delineated knowledge structures. This result draws upon a characterization of the meshing of finite or infinite collections of knowledge structures, which extends and generalizes previous results on the binary case. The discussion covers implications for knowledge assessment and for practical applications, such as integrating skill assignments coming from different experts or distributed resources in technology-enhanced learning.     

Religious Diversity From a Jewish Perspective

The exploration of spiritual and religious diversity may receive less attention in counselor education than is warranted, resulting in counselors who are unprepared to deal with spiritual and religious issues in counseling. This trend could have a negative impact on Jewish clients, as well as on other religious clients, who feel that issues related to their identity are ignored. The Council for Accreditation of Counseling and Related Educational Programs (2001) has recognized that religious diversity is an integral component of the multicultural counseling movement, but counselor education and training programs, as a whole, still need to embrace this standard.
