Zn1???xCoxO (ZC) [x?=?0, 1, 3, 5, 7 and 9?mol%] thin films were prepared by sol–gel combined metallo-organic decomposition method. The films were deposited on the Si substrate with spin-coating technique and annealed at 600?°C for 3?h. X-ray diffraction pattern shows the formation hexagonal wurtzite phase and distortion (c/a) decreases with increasing Co concentration in ZnO. The average grain size is measured using Scherer relation. Atomic force microscopy is used to confirm the formation of nanograins resulted by the use of polyethylene glycol as surfactant. The photoluminescence was recorded by using He-Cd laser of excitation wavelength 325?nm in wavelength region of 350–650?nm which exhibits some influence of Co doping on the multiplication of defects such as O vacancies, Zn interstitials and grain boundary defects. All thin films show room temperature ferromagnetism except pure ZnO which is diamagnetic and 9?mol% of Co shows paramagnetism. This behaviour is interpreted as due to fluctuations in the magnetic ordering, depending on grain size and site location in grain boundaries or oxygen vacancies. 相似文献

Children's performance on cognitive tasks is often described in categorical terms in that a child is described as either passing or failing a test, or knowing or not knowing some concept. We used binomial mixture models to determine whether individual children could be classified as passing or failing two search tasks, the DeLoache model room task and the Berthier et al. door task. The data support categorical classification of the children and suggest that the increase in average proportion correct with age is the result of an increasing proportion of children who can solve the tasks. Performance on the two tasks was concordant, and improving performance could be due to advances in a single psychological ability, such as cognitive control.

People can experience positive changes even in the midst of adversity and loss. We investigated character strengths following three recent shooting tragedies. Using an Internet database of respondents to the Values in Action Inventory of Strengths (VIA-IS), we compared responses from three groups of participants (N?=?31,429) within close proximity of each event: those who completed it eight months prior to the event, and one month and two months after. Results suggested that for one of the events, participants who completed the VIA-IS after the event showed slightly different levels of self-reported character strengths compared to participants who completed the VIA-IS before the event, with some mean levels higher and others lower. The observed differences in character strengths were inconsistent across follow-up periods, and effect sizes were small (d values from –0.13 to 0.15). These findings raise questions about whether and how tragedies might catalyze differences in character strengths. 相似文献

The current study investigates how attitudes towards seeking psychological help relate to internal working models of attachment (self-model and other-model) and ruminative tendencies. The study includes 589 Turkish university students (278 females, 308 males and 3 unknown) by implementing a convenient sampling procedure. The average age of the participants was 22.4 years (SD = 2.2). Participants were administered the Attitudes toward Seeking Psychological Help-Short, the Relationship Questionnaire and the Rumination Scale. The results of the study indicate that the other-model and rumination have a relationship to women's help-seeking attitudes whereas the self-model has a relationship to men's help-seeking attitudes. The results are discussed in light of the related literature. 相似文献

The theoretical basis of occupational therapy interventions was investigated in two mental health facilities in the Midwestern United States. Using retrospective cohort and grounded theory designs, 121 medical records were reviewed and five occupational therapy practitioners were interviewed. Theoretical reasoning was not explicitly documented, but according to analysis, the behavioral/cognitive-behavioral model, client-centered models, and the model of human occupation were the most frequently used theories to guide interventions. Lack of documentation of theory use has significant implications for the value accorded to occupational therapy skills in health care. A larger study is recommended to increase external generalizability of the findings. 相似文献

Abstract Taylor (1995) constructed a comprehensive framework of stress and adaptation, which considers internal and external resources/impediments as moderators, based on previous studies and models. However, most past research used correlation designs and has not taken into account all of the framework's components within one study. This study tested the effects of the event (minor, major), primary appraisal (benign, severe), coping (problem-focused coping (PFC) versus emotion-focused coping), external resources (with/without social support), and internal impediments (hostility), on estimated distress (dependent variable) in written imagined stressful daily scenarios. All components except hostility were experimentally manipulated within subjects in the scenarios. The scenarios were rated by 281 Dutch students. The variables event, appraisal, and social support significantly and independently affected estimated distress. Event and appraisal synergistically interacted in relation to estimated distress. Finally, appraisal interacted with coping such that the distress-reducing effects of PFC occurred only in benign events, while coping did not affect estimated distress in severely appraised events. This study experimentally tested most components of Taylor's framework, and showed that events, appraisal, and social resources were independent determinants of estimated distress, and that appraisal interacts in a complex manner with the event and with coping. 相似文献

Abstract The objective of this study was to investigate the mediating role of coping strategies in the relationships between neuroticism, social support, and depression in two groups of adolescents: earthquake group and examination group. Adolescents facing earthquake stress (earthquake group, N=219) completed measures of neuroticism, perceived social support, coping strategies, and self-rating depression. Similarly, adolescents facing examination stress (examination group, N=241) completed the same measures. Results indicated that the earthquake group reported more use of secondary control engagement coping, whereas the examination group reported more use of primary control engagement coping. In addition, neuroticism was more strongly associated with coping in earthquake group and coping strategies explained significantly larger part of the relationship between neuroticism and depression. In contrary, perceived social support was more strongly associated with coping in examination group, and coping strategies explained significantly larger part of the relationship between perceived social support and depression. 相似文献

Coping is related to mental and physical health outcomes, but cultural and societal differences may influence its nature and structure. This study reports on the adaptation of the Coping Responses Inventory for Adult (CRI-A) to the Iranian social and cultural context. Study 1 was designed to obtain qualitative data and test the construct and discriminative validity of coping scales. Factor analysis of the CRI and Iranian items yielded seven factors: Religious Coping, Problem Solving, Cognitive Avoidance, Positive Reappraisal, Seeking Guidance and Support, Seeking Alternative Rewards, and Acceptance/Resignation. Internally, consistencies varied considerably from 0.92 to 0.53. All sub-scales from the Coping Responses Inventory for Adult (CRI-A) were resistant to social desirability biases with the exception of Religious Coping and Problem Solving. In Study 2, the replicability of the adapted CRI-A factorial structure and concurrent validity for the newly developed religious coping sub-scale was demonstrated. Given the importance of the role of religious coping in health and well-being outcomes, the expression and use of which may be substantially influenced by cultural practices and norms, it is recommended that future research pursues the validation of context-specific constructs of religious and spiritual coping. 相似文献

Forgiveness is a complex construct with an important role in religious traditions worldwide, and is associated with mental and physical health outcomes. This seven-year longitudinal study examined changes within individuals during, and differences based on birth cohort, in forgiveness during late life. Growth curve analysis was used to analyse the general pattern of change across the course of older adulthood in eight dimensions related to forgiveness. Increases over time were observed in forgiveness of others, conditionality of forgiveness of others, forgiveness of self, feelings of being forgiven by God, and feelings of being forgiven by others. Decreases over time were observed in difficulty forgiving oneself, and perceptions of conditionality in God's forgiveness. Religious commitment was related to reporting more a more forgiving attitude on seven of these dimensions, but also to more perceived conditionality in God's forgiveness. Finally, differences in mean levels of forgiveness emerged between birth cohorts. 相似文献

The author discusses some striking convergences which appear in the thought of two unsettling and powerfully stimulating personalities of the 20th century: John Cage in music and art, and W.R. Bion in psychoanalysis. Both foster openness to the unknown and the need to tolerate 'uncertainties, mysteries, doubts', arguing for an attitude requiring negative valence and receptive emptiness. In their search for fresh personal awareness of reality aimed at allowing mental transformation and growth, both strive to disturb intellectual comfort and do not hesitate to use pro(e)vocative and even shocking means. They both propose an attitude towards tradition which demands the freedom to use and recreate inherited knowledge in a personal and innovative way. Finally, both Cage and Bion maintained a highly auto-reflective attitude, carefully considering the artist's/psychoanalyst's contribution to the process of art and psychoanalysis. These convergences probably represent important and wider contemporary cultural trends which permeate in their different realizations. 相似文献
