Gender,Leadership Orientation,and Effectiveness: Testing the Theoretical Models of Bolman & Deal and Quinn

This study examined the differences in gender between a “balanced” or “unbalanced” orientation of leadership, leadership characteristics, and the perceived effectiveness of educational leaders through subordinate responses in the context of Bolman and Deal's (1991, 1997) four-frame leadership theory and Quinn's (1988) competing values model. The findings suggest that any differences in the perceived effectiveness of educational leaders in the three leadership type groups are equally true for male and female leaders, and that male and female educational leaders were perceived to be equally effective in their respective organizations despite the stereotypical connotations asserted in previous research. In addition, no significant differences were found between men and women in their leadership characteristics, which stands in contrast to extant research-supported evidence. This study analyzed the ratings of 57 leaders (males = 31; females = 26) by 472 subordinate participants (males = 234; females = 238) from lower, middle, and upper management levels in secondary and postsecondary institutions. Approximately 60% of the participants and one third of the educational leaders were African Americans.     

The effects of undergarment type on the urinary continence of toddlers

There is a growing trend toward later toilet training of typically developing children. This trend is a problem for caregivers and professionals who work with young children, because it is associated with a number of costs and health risks in child-care settings. Results of a recent study (Tarbox, Williams, & Friman, 2004) suggest that wearing underwear may facilitate the development of toileting skills. Based on these findings, we examined the effects of wearing disposable diapers, disposable pull-on training pants, and underwear on urinary continence of 5 typically developing toddlers in a child-care setting. Underwear decreased incontinence and increased continent urinations for 2 of the 5 participants, produced no improvement in 2 participants, and when combined with increased fluid intake and longer sitting periods, produced some favorable trends for the 5th participant.     

The ecological imagination

This paper offers a psychoanalytic exploration of meaning within the concept of ecology. From a starting point in the experience of primal anxiety, originating in the work of Freud, Jung and Klein, links are made to cultural themes through a developing comparison of case studies in literature, mythology, the public sphere and clinical practice. It is argued that the application of psychoanalytic ideas to environmental concern has validity. The idea emerges that individual and public attitudes to our environment might be open to positive change through an appreciation of the concept of early anxiety, currently available to us in work of the imagination.     

Audio-visual integration of emotional cues in song

We examined whether facial expressions of performers influence the emotional connotations of sung materials, and whether attention is implicated in audio-visual integration of affective cues. In Experiment 1, participants judged the emotional valence of audio-visual presentations of sung intervals. Performances were edited such that auditory and visual information conveyed congruent or incongruent affective connotations. In the single-task condition, participants judged the emotional connotation of sung intervals. In the dual-task condition, participants judged the emotional connotation of intervals while performing a secondary task. Judgements were influenced by melodic cues and facial expressions and the effects were undiminished by the secondary task. Experiment 2 involved identical conditions but participants were instructed to base judgements on auditory information alone. Again, facial expressions influenced judgements and the effect was undiminished by the secondary task. The results suggest that visual aspects of music performance are automatically and preattentively registered and integrated with auditory cues.     

Short horizons and tempting situations: Lack of continuity to our future selves leads to unethical decision making and behavior

People who feel continuity with their future selves are more likely to behave in ethically responsible ways as compared to people who lack continuity with their future selves. We find that individual differences in perceived similarity to one’s future self predicts tolerance of unethical business decisions (Studies 1a and 1b), and that the consideration of future consequences mediates the extent to which people regard inappropriate negotiation strategies as unethical (Study 2). We reveal that low future self-continuity predicts unethical behavior in the form of lies, false promises, and cheating (Studies 3 and 4), and that these relationships hold when controlling for general personality dimensions and trait levels of self-control (Study 4). Finally, we establish a causal relationship between future self-continuity and ethical judgments by showing that when people are prompted to focus on their future self (as opposed to the future), they express more disapproval of unethical behavior (Study 5).     

Characterisation of magnesium oxide and its interface with α-Mg in Mg–Al-based alloys

Magnesium oxide (MgO) films and particles have been collected by pressurised filtration of a Mg-8.6wt%Al-0.67wt%Zn (AZ91D) alloy melt. The morphology of the oxides and their interfaces with the α-Mg phase were investigated by high-resolution transmission electron microscopy. It was found that the oxide films consisted of large numbers of sub-micrometre-sized MgO particles, and that melt shearing can effectively break up the oxide films and disperse the oxide particles. For the first time, orientation relationships (ORs) of OR I: [1?1?1]_MgO～2° from (0?0?0?1)_α-Mg and (0?1?1)_MgO?//[2?1?1?0)_α-Mg; and OR II: (1?1?1)_MgO//(1?1?0?1)_α-Mg and [0?1?1]_MgO//[1?2?1?1]_α-Mg, were observed between the MgO particles and the α-Mg matrix. The calculated Bramfitt planar disregistries were 5.5% and 2.5% for the two ORs, respectively, indicating good lattice matching between MgO and α-Mg at the interface. With the evidence of grain refinement effect observed in the sheared AZ91D magnesium alloy, the possibility of MgO particles to act as potent nucleants for heterogeneous nucleation of α-Mg grains is discussed in terms of the crystallographic criterion.     

The Role of Perspective Taking and Empathy in Children's Machiavellianism,Prosocial Behavior,and Motive for Helping

Fourth- and fifth-grade children (N = 117) were categorized into high- and low-empathy and affective-perspective-taking (APT) groups based on their scores on the Bryant (1982) empathy scale and a modified version of the Rothenberg (1970) and Silvern, Waterman, Sobesky, and Ryan (1979) APT measures. Children in the low-empathy/high-APT group had significantly higher Machiavellianism scores on Braginsky's (1970) measure than did children in the other empathy/APT groups. Highly empathic children were rated by their teachers as more helpful under certain circumstances and cited other-oriented reasons for their own helping behavior more frequently than did less empathic children.     

Changes in meaning in life across the course of psychodynamic psychotherapy

Using the Meaning in Life Questionnaire (MLQ), we studied Presence and Search for meaning for 34 adult clients in psychodynamic psychotherapy. Clients completed the MLQ and Outcome Questionnaire (OQ) before intake and after every eight sessions. Variance in Presence scores was mostly attributable to clients; variance in Search scores was mostly attributable to clients and therapists. Clients initially high in Presence decreased and then increased back to initial levels; clients initially low in Presence increased and then decreased back to initial levels. Clients initially low in Search increased and then leveled off; clients initially high in Search decreased and then leveled off. In lagged cross panel analyses, when clients decreased in psychological distress during one eight-week time period, they increased in Presence during the next eight-week time period; when they increased in psychological distress during one eight-week time period, they increased in search in the next time period. Excerpts from post-therapy interviews illustrate the process of working with meaning in life in psychotherapy. Implications for practice and training are discussed.     

Presentation modality,rehearsal-prevention conditions,and auditory confusions in tests of short-term memory

Ss were presented four-letter sequences either auditorily or visually and asked for ordered recall after 0, 2.1, 4.2, 8.4, or 12.6 sec of digit categorization. Three different rehearsal-prevention conditions were required during presentation of the memory set: categorizing, suppressing (saying "dah"), or pronouncing each letter. Recall was worst after categorizing, best after pronouncing. Auditory presentation led to better recall after no delay but more rapid forgetting than visual presentation, regardless of the rehearsal-prevention condition. These results, and analyses of auditory confusions, are inconsistent with a view of memory which asserts that sensory information is encoded auditorily regardless of presentation modality or vocalization behavior during presentation.
