The Convergent Validity of Four Burnout Measures in a Chinese Sample: A Confirmatory Factor‐Analytic Approach

The purpose of this paper is to study the convergent validity of the four most widely used burnout measures in a sample of Chinese nurses (N= 717). First, Structural Equation Modeling was used to investigate the factor structure of scores produced by the Maslach Burnout Inventory‐General Survey (MBI‐GS), the Burnout Measure (BM), the Shirom‐Melamed Burnout Measure (SMBM), and the Oldenburg Burnout Inventory (OLBI). Next, several competing models were tested to investigate the convergent validity of these four burnout instruments. The final results suggest that burnout is best conceived of as a multidimensional construct consisting of exhaustion and withdrawal, which are two related but conceptually distinct aspects. In addition, positively phrased items should be dropped from burnout measures for they constitute a separate factor that is considered to be an artifact.     

论选择性执法的法律规制——兼及“钓鱼式执法”的法律约束

选择性执法是行政主体应对复杂的社会情势和违法行为高度不均衡分布的一种手段。选择性执法具有权力性、不确定性和目的性特征,它在使行政主体获得高度的灵活性和行政效率,有利于完成行政执法任务的同时,也牺牲了法的稳定性和权威性,助长了行政执法中的机会主义,并鼓励人们守法上的投机心理和行为,不利于法治。应当对选择性执法持较为严格的态度,保证其执法目的的正当性,并采取具体的方法加以规制。     

Monocular-contingent and binocular-contingent aftereffects

Alternate monocular and binocular exposure to complementary stimulation can yield opposite but coexisting aftereffects that are contingent on whether the test display is viewed with one eye or two eyes. The motion aftereffect was studied by adapting each eye separately to a contracting spiral and both eyes together to an expanding spiral. The stationary test spiral subsequently appeared to be expanding when viewed monocularly, but to be contracting when it was seen with both eyes open. With respect to the McCollough effect, after monocular exposure to red-vertical and green-horizontal gratings and binocular exposure to red-horizontal and green-vertical gratings, the appearance of the color of the test gratings when viewed with one eye was different from that when viewed with both eyes. Opposite, coexisting aftereffects induced by complementary stimulation can be interpreted as evidence that there are unique binocular aspects to visual function.     

Modeling feature perception in brief displays with evidence for positive interdependencies

Recent studies have begun to test certain fundamental assumptions underlying popular models of feature perception. This research is continued here. It was discovered that every basic assumption that was open to test in the present study was disconfirmed. However, several new characteristics of line and curve feature perception were discovered: (1) Feature perception sensitivity was inversely related to the number of features present in a stimulus pattern, and the decision criteria for reporting a feature decreased with the number of features contained in a pattern; (2) the decrements in sensitivity reported in (1) were greater for features lying inside a pattern than for those on the exterior; and (3) feature perception sensitivity actually improved if another feature was known to be correctly perceived during the same trial. Likewise, feature sensitivity decreased if another feature was missed on any trial. At the present time, a system that first extracts global and then local (more detailed) featural information provides a basis that qualitatively accounts for our findings and is also compatible with several other studies in the literature.     

Teaching self-control to reduce overt food stealing by children with autism and developmental disorders

Food stealing is often a serious behavioral problem among children with diagnoses of autism and other developmental disorders. Very few empirical studies concerning this behavioral challenge have been reported. We applied a correspondence training procedure to teach self-control as replacement behavior to four children with autism and developmental disorders who displayed food stealing in the community. A changing criterion design embedded within a nonconcurrent multiple-probe across participants design was used. The treatment succeeded for all four participants by increasing latency to eating highly preferred food to a predetermined criterion and reducing occurrences of food stealing to zero. Three participants generalized the replacement behavior to natural settings and maintained the behavior for 2 weeks, 1 month, 2 months, 3 months, and 4 months. One participant without expressive language was taught successfully during treatment trials but failed to maintain and generalize the behavior. A functional relation between delaying food eating and Say-Do correspondence training was demonstrated.     

Brain bases of English morphological processing: A comparison between Chinese-English,Spanish-English bilingual,and English monolingual children

How do early bilingual experiences influence children's neural architecture for word processing? Dual language acquisition can yield common influences that may be shared across different bilingual groups, as well as language-specific influences stemming from a given language pairing. To investigate these effects, we examined bilingual English speakers of Chinese or Spanish, and English monolinguals, all raised in the US (N = 152, ages 5–10). Children completed an English morphological word processing task during fNIRS neuroimaging. The findings revealed both language-specific and shared bilingual effects. The language-specific effects were that Chinese and Spanish bilinguals showed principled differences in their neural organization for English lexical morphology. The common bilingual effects shared by the two groups were that in both bilingual groups, increased home language proficiency was associated with stronger left superior temporal gyrus (STG) activation when processing the English word structures that are most dissimilar from the home language. The findings inform theories of language and brain development during the key periods of neural reorganization for learning to read by illuminating experience-based plasticity in linguistically diverse learners.

Digital literacy and green consumption behavior: Exploring dual psychological mechanisms

Green consumption has been developing into a booming trend due to alarming environmental problems. This study examines the relationship between the consumers' digital literacy and green consumption behavior and explores two different mechanisms based on social cognitive theory and self-regulatory theory. The cognition-based mechanism includes self-efficacy and outcome expectation; the affect-based mechanism includes anticipated pride and anticipated guilt. In addition, we investigate how green product availability moderates the relationships between four mediators and green consumption behavior. Across two studies, the results indicate that the consumers' digital literacy influences green consumption behavior through self-efficacy, outcome expectation, anticipated pride, and anticipated guilt. Moreover, green product availability boosts the effects of self-efficacy and anticipated pride on green consumption behavior. Our research has theoretical contributions to understanding the formation of green consumption behavior. It also provides practical implications for how to effectively guide and promote green consumption behavior.
