    In: Perceptual and Motor Skills, SAGE Publications, Vol. 106, No. 3 ( 2008-06), p. 811-820
    Abstract: The purpose was to examine the different aspects of perfectionism and athletes' burnout. College athletes ( N = 320) with mean age of 19.7 yr. ( SD = 1.4) completed the Chinese version of the Multiple Perfectionism Scale for Sport and the Eades' Athlete Burnout Inventory. Results indicated that perfectionism could be separated into adaptive and maladaptive perfectionism. Adaptive perfectionism was linked to reduced athletes' burnout while maladaptive perfectionism was associated with athletes' burnout. In addition, significant interaction was found between adaptive perfectionism and maladaptive perfectionism on athletes' burnout. Results suggest that high maladaptive perfectionism and low adaptive perfectionism corresponds to higher scores on athletes' burnout. Perfectionism should not be treated as an all-or-nothing disposition. The extent of athlete burnout can vary with the interaction effects of the two types of perfectionism. In terms of practical implications in intervention work, coaches and sport psychologists should try to reduce athletes' maladaptive perfectionism and increase adaptive perfectionism.

    In: Psychological Reports, SAGE Publications, Vol. 102, No. 3 ( 2008-06), p. 920-926
    Abstract: This study examined the association of scores on measures of traditionality and gratitude. Briefly defined, traditionality refers to how strongly one endorses the traditional value of submission to authority for harmony and benefits in a collective group. Traditional Taiwanese culture is linked with collectivism, and the society tends to encourage members to respect authority and harmony. As people of a collectivistic view seek to maintain harmony within the group, gratitude and reciprocity of good is expected from members. Nevertheless, traditionality of values differs among group members, as is also true for gratitude. It is not known how scores on traditionality might relate to feelings of gratitude among athletes in the competitive sports setting. 289 Taiwanese high school athletes were administered the Sport-domain Gratitude Questionnaire by Chen and Kee and the Traditionality Scale by Kao and Lu. Data, subjected to structural equation modeling, show that traditionality scores were related to those on gratitude. Implications and limitations were discussed.

    Abstract: Optimism is important in enhancing human psychological and physical well-being; however, the association of optimism with burnout has received little attention in sport psychology. This study recruited 139 young volleyball players ( M = 16.3 yr., SD = 0.8) to examine this relation. Athletes completed the Chinese version of the Life Orientation Test at Time 1 and 4 mo. later (Time 2). The Chinese version of the Athlete Burnout Questionnaire was also administered. Analysis showed scores on optimism were negatively related to athletes' burnout scores.

    Abstract: Self-handicapping is a maladaptive behavior which undermines students' achievements, but the antecedents of self-handicapping are not well studied in physical education. The aim was to examine the relations of implicit theory of abilities and self-handicapping in physical education. 264 college students, whose mean age was 20.3 yr. ( SD= 1.7), completed the Conceptions of the Nature of Athletic Ability Questionnaire-2 and Self-handicapping Scale for Sport. Analysis indicated entity beliefs positively predicted reduced effort and making excuses. Also, incremental beliefs negatively predicted reduced effort. Results are discussed in terms of implicit theory of ability and self-handicapping. Directions for research and implications are stated.

    Abstract: The retinoblastoma protein (Rb) plays a critical role in cell proliferation, differentiation, and development. To decipher the mechanism of Rb function at the molecular level, we have systematically characterized a number of Rb-interacting proteins, among which is the clone C5 described here, which encodes a protein of 1,978 amino acids with an estimated molecular mass of 230 kDa. The corresponding gene was assigned to chromosome 14q31, the same region where genetic alterations have been associated with several abnormalities of thyroid hormone response. The protein uses two distinct regions to bind Rb and thyroid hormone receptor (TR), respectively, and thus was named Trip230. Trip230 binds to Rb independently of thyroid hormone while it forms a complex with TR in a thyroid hormone-dependent manner. Ectopic expression of the protein Trip230 in cells, but not a mutant form that does not bind to TR, enhances specifically TR-dependent transcriptional activity. Coexpression of wild-type Rb, but not mutant Rb that fails to bind to Trip230, inhibits such activity. These results not only identify a coactivator molecule that modulates TR activity, but also uncover a role for Rb in a pathway that responds to thyroid hormone.

    Neurofibromin Mediates FAK Signaling in Confining Synapse Growth at Drosophila Neuromuscular Junctions

    Abstract: Neurofibromatosis type I (NF1), caused by the mutation in the NF1 gene, is characterized by multiple pathological symptoms. Importantly, ∼50% of NF1 patients also suffer learning difficulty. Although downstream pathways are well studied, regulation of the NF1 -encoded neurofibromin protein is less clear. Here, we focused on the pathophysiology of Drosophila NF1 mutants in synaptic growth at neuromuscular junctions. Our analysis suggests that the Drosophila neurofibromin protein NF1 is required to constrain synaptic growth and transmission. NF1 functions downstream of the Drosophila focal adhesion kinase (FAK) Fak56 and physically interacts with Fak56. The N-terminal region of NF1 mediates the interaction with Fak56 and is required for the signaling activity and presynaptic localization of NF1. In presynapses, NF1 acts via the cAMP pathway, but independent of its GAP activity, to restrain synaptic growth. Thus, presynaptic FAK signaling may be disrupted, causing abnormal synaptic growth and transmission in the NF1 genetic disorder.

    Abstract: Retrograde signals induced by synaptic activities are derived from postsynaptic cells to potentiate presynaptic properties, such as cytoskeletal dynamics, gene expression, and synaptic growth. However, it is not known whether activity-dependent retrograde signals can also depotentiate synaptic properties. Here we report that laminin A (LanA) functions as a retrograde signal to suppress synapse growth at Drosophila neuromuscular junctions (NMJs). The presynaptic integrin pathway consists of the integrin subunit βν and focal adhesion kinase 56 (Fak56), both of which are required to suppress crawling activity-dependent NMJ growth. LanA protein is localized in the synaptic cleft and only muscle-derived LanA is functional in modulating NMJ growth. The LanA level at NMJs is inversely correlated with NMJ size and regulated by larval crawling activity, synapse excitability, postsynaptic response, and anterograde Wnt/Wingless signaling, all of which modulate NMJ growth through LanA and βν. Our data indicate that synaptic activities down-regulate levels of the retrograde signal LanA to promote NMJ growth.

    Abstract: Human genetic history in East Asia is poorly understood. To clarify population relationships, we obtained genome-wide data from 26 ancient individuals from northern and southern East Asia spanning 9500 to 300 years ago. Genetic differentiation in this region was higher in the past than the present, which reflects a major episode of admixture involving northern East Asian ancestry spreading across southern East Asia after the Neolithic, thereby transforming the genetic ancestry of southern China. Mainland southern East Asian and Taiwan Strait island samples from the Neolithic show clear connections with modern and ancient individuals with Austronesian-related ancestry, which supports an origin in southern China for proto-Austronesians. Connections among Neolithic coastal groups from Siberia and Japan to Vietnam indicate that migration and gene flow played an important role in the prehistory of coastal Asia.
