Burnout and duration of service among Chinese voluntary workers

A survey study conducted among 226 Chinese voluntary workers in Hong Kong showed that satisfaction with voluntary work, integration into the voluntary institution, and burnout syndromes contributed to volunteers' expected duration of service. Regression analyses also showed that different sets of variables predicted different spans of expected duration of service. Work satisfaction was the most salient predictor for expected duration of service from six months to ten years. Lack of personal accomplishment predicted expected duration of service for six to twelve months, whereas emotional exhaustion and depersonalization influenced volunteers' expectation to continue in the service for five to ten years.     

An investigation of perceptual and decisional influences on the perception of hierarchical forms

When observers are asked to identify the global and local dimensions of hierarchical forms, their responses are typically faster when the dimensions are consistent rather than inconsistent. This effect, which we refer to as the dimensional consistency effect, has been demonstrated numerous times in paradigms requiring responses to a single dimension. However, most hypotheses regarding dimensional consistency effects address the simultaneous perception of both dimensions, and the manner in which the information about these dimensions may (or may not) 'interact'. Most explanations of the dimensional consistency effect attribute the effect to perceptual influences. The present study uses the constructs of general recognition theory (Ashby and Townsend, 1986 Psychological Review 93 154-179) to represent the source of the effect in terms of both perceptual and decisional influences. In addition, a complete identification response paradigm was used to collect data on the simultaneous perception of both global and local dimensions of hierarchical forms. Analyses of multidimensional signal detection measures and fits of parametric models of the perceptual space were used to guide inferences, with all sources of evidence pointing to both perceptual and decisional influences.     

Relations between maternal power-assertive parenting and adjustment in Chinese children: A longitudinal study

This 1-year longitudinal study examined relations between maternal power-assertive parenting and children's social, academic and psychological adjustment in China. Participants were 316 elementary school children (mean age = 11 years, 153 boys). Maternal power-assertive parenting was assessed using children's self-reports. Data on children's social and school adjustment were obtained from peer evaluations and teacher ratings. In addition, children completed measures of loneliness and depression. Cross-lagged analyses indicated that whereas maternal power-assertive parenting was only related to later academic adjustment, children's adjustment in socioemotional and academic domains contributed to the prediction of later maternal power-assertive parenting. The results were discussed in the Chinese context.     

Further investigation of increasing vocalizations of children with autism with a speech-generating device

We replicated and extended the findings of Gervarter et al. (2016) by using prompting and reinforcement to produce increased vocal speech with 3 young children diagnosed with autism spectrum disorder (ASD) who used a speech generating device (SGD). We extended Gervarter et al. by adopting a more robust experimental design, conducting session-by-session preference assessments, and measuring the emergence of novel vocalizations. The frequency of vocalizations increased for all 3 participants after the introduction of an echoic prompt. These results suggest that SGD-based interventions may lead to increased vocal output for children with ASD.     

Sensitivity to status-based rejection: implications for African American students' college experience

The authors proposed a process model whereby experiences of rejection based on membership in a devalued group can lead people to anxiously expect, readily perceive, and intensely react to status-based rejection. To test the model, the authors focused on race-based rejection sensitivity (RS-race) among African Americans. Following the development and validation of the RS-Race Questionnaire (Studies 1 and 2), the authors tested the utility of the model for understanding African American students' experiences at a predominantly White university (Study 3). Students high in RS-race experienced greater discomfort during the college transition, less trust in the university, and relative declines in grades over a 2- to 3-year period. Positive race-related experiences, however, increased feelings of belonging at the institution among students high in RS-race.     

Phenomenology of autobiographical memories: the memory experiences questionnaire

The phenomenology of autobiographical memories varies on a number of dimensions: some memories are vivid and others dim; some are emotionally intense and others lack emotional content. The present research sought to develop a psychometrically-sound scale to assess the entire range of dimensions on which autobiographical memories differ. We reviewed the literature on memory experiences and identified 10 relevant dimensions: Vividness, Coherence, Accessibility, Time Perspective, Sensory Details, Visual Perspective, Emotional Intensity, Sharing, Distancing, and Valence. We constructed a comprehensive item pool to assess these dimensions and, using data from several large samples (Ns=941; 510; 212), we showed that: (a) all 10 scales had adequate reliability (median alpha=.87; range=.72 to .97), (b) the 10-factor structure provided a good fit to the data, and (c) gender, personality, and memory recency had theoretically meaningful relations with the 10 scales. For example, gender and ethnicity differences in phenomenology were mediated by memory content, and early and recent memories had distinct phenomenologies. The discussion focuses on the theoretical and practical utility of the 10 scales.

Microstructure and superconductivity of bulk BPSCCO/LPMO composite

Bulk superconducting (SC) ceramics containing BPSCCO and LPMO (Lanthanum/Lead – manganite phase) have been produced. The initial components were prepared by a low-temperature Pechini method. The submicron powders in weight ratio 90/10 Bi_1.6Pb_0.4Sr₂Ca₂Cu₃O_z/La_0.6Pb_0.4MnO₃ (nominal composition) were heat treated at 840°C. The duration of the heat treatment effect (60 and 100?h) of the composite on the transformation of the microstructure was studied. The obtained composites were analyzed by scanning electron microscopy (SEM) and by the method of energy-dispersive X-ray spectroscopy (EDX). They contain several phases. It was established that the SC 2212 phase is predominate in the composite. The phase La_0.6Pb_0.4MnO₃ transforms in solid solution with preliminary composition La_0.5(Sr?+?Ca)_0.5Mn_{1? z} Cu _z O₃, which after full replacement of the La and Mn ions leads to the appearance of phases with nominal composition Sr_{1? x} Ca _x CuO _y . AC and DC magnetization measurements were used to study the SC and magnetic properties of the samples. Both samples are SC with critical temperatures 75 and 77?K, respectively. It was concluded that the SC and magnetic phases stably coexist in the composite sintered at 60?h heat treatment at 840°C.
