库车坳陷西段第三系盐上层基底沉降分析

根据地震层速度资料与地层砂泥岩含量的关系,求得新生界各层砂泥岩含量,结合经验的和实测的其它必要参数,计算了库车坳陷西段第三系盐上层的总沉降和构造沉降.根据变化趋势,可将沉降曲线划分为两种类型:上凸型和下凹型,北单斜带为下凹型,其余构造带为上凸型,沉降曲线不同阶段沉降速度的变化充分反映了天山造山带与库车坳陷的盆山耦合作用.根据总沉降和构造沉降曲线的关系,上凸型沉降曲线又可进一步划分为两个亚类,第一亚类为构造沉降曲线与总沉降曲线协调变化;第二亚类为两者不协调变化,反映盐的流动特点,这种现象在克拉苏构造带的南亚带最明显.     

含蜡原油结构抑制机理研究

基于含蜡模拟油加抑制剂GY1前后的特征温度、流变参数、析蜡量及微观结构的实验分析,研究含蜡原油结构抑制机理.结果表明:①抑制剂GY1不能阻止蜡结晶与晶核的形成,反而使析蜡量有所增加;②对于含粗晶蜡的模拟油,抑制剂GY1将阻碍其蜡晶生长,使蜡晶尺寸变小、非对称性增大,进而增强蜡晶颗粒相互作用与连接趋势,宏观表现为降凝与降粘效果差;③对于含微晶蜡的模拟油,抑制剂GY1有助于其蜡晶的聚集生长,使蜡晶尺寸变大、表面结合力降低,进而抑制蜡晶颗粒相互作用与连接趋势,宏观表现为降凝降粘效果显著;④含蜡原油结构抑制的机理就是使蜡晶颗粒聚集变大、提高其对称性、降低其分散度、抑制其相互作用与连接的机理.     

Using Taxometric Analysis to Distinguish a Small Latent Taxon From a Latent Dimension With Positively Skewed Indicators: The Case of Involuntary Defeat Syndrome.

Joining the debate on the structure of depression, S. R. H. Bearh and N. Amir (2003) analyzed college students' responses to 6 Beck Depression Inventory (BDI) items with predominantly somatic content and concluded that they identified a small latent taxon corresponding to involuntary defeat syndrome. An exact replication of these analyses yielded virtually identical taxometric results, but parallel analyses of simulated taxonic and dimensional comparison data matching the intercorrelations and skewed distributions of the BDI items showed the results to be more consistent with dimensional than with taxonic latent structure. Analyses in a clinical sample with nonskewed indicators further supported a dimensional interpretation. The authors discuss methodological strategies for conducting and interpreting taxometric analyses under the adverse conditions commonly encountered in psychopathology research, including skewed indicators and small putative taxa.

Conceptualizing and Measuring Personality Vulnerability to Depression: Comment on Coyne and Whiffen (1995).

J. C. Coyne and V. E. Whiffen (1995) reviewed research on personality vulnerability to depression, focusing on S. J. Blatt's (1974, 1990) concepts of dependency and self-criticism and A. T. Beck's (1983) concepts of sociotropy and autonomy. The authors discuss 6 issues raised in that review: (a) the typological or dimensional nature of vulnerability, (b) the theoretical implications of "mixed" vulnerability, (c) the relations of vulnerability to Neuroticism. (d) the potential confounding of vulnerability with concurrent depression, (e) the potential confounding of vulnerability with social context, and (f) the differentiation of dependency from relatedness. The authors conclude that Blatt's and Beck's concepts are continuous, nearly orthogonal dimensions that can be identified and measured independently from Neuroticism, depression, and social context.

Parent-Infant Synchrony and the Social-Emotional Development of Triplets.

To study the social-emotional development of triplets, 23 sets of triplets, 23 sets of twins, and 23 singleton infants (N=138) were followed from birth to 2 years. Maternal depression and social support were assessed in the postpartum period, mother-infant and father-infant interaction and the home environment were observed at 3 months, a separation-reunion episode and a maternal interview were conducted at 12 months, and infant behavior problems were evaluated at 24 months. Lower parent-infant synchrony was observed for triplets. Triplets showed less distress during maternal separation and less approach at reunion. Mothers reported lower adjustment and differentiation among siblings for triplets than for twins. Higher internalizing problems were reported for triplets, and the triplet with intrauterine growth retardation showed the poorest outcomes. Behavior problems were predicted by medical risk, maternal depression, parent-infant synchrony, infant approach, and mother adjustment. Discussion focuses on developmental risk when the exclusivity of the parent-infant relationship is compromised. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Finding Benefit in Breast Cancer During the Year After Diagnosis Predicts Better Adjustment 5 to 8 Years After Diagnosis.

Cancer patients experience positive as well as adverse consequences from diagnosis and treatment. The study reported here examined longer term reverberations of such experiences. A set of benefit-finding items along with measures of well-being were completed by 230 early-stage breast cancer patients in the year postsurgery. Four to 7 years later, 96 of them again completed measures of well-being. Controlling for initial distress and depression, initial benefit finding in this sample predicted lower distress and depression at follow-up.

Unipolar Depression, Life Context Vulnerabilities, and Drinking to Cope.

This study followed baseline samples of 424 unipolar depressed patients and 424 community controls across 10 years to investigate the association between depression and alcohol-related coping and to examine how life context vulnerabilities underlie the risk for depressed individuals to rely on drinking to cope. Findings supported all hypotheses. Depressed patients engaged in more drinking to cope than did community controls. Within individuals, more negative life events and less family support were associated with more drinking to cope across the 4 observations. Depressed patients experienced more negative life events and less family support than did community controls. These underlying life context vulnerabilities explained the relationship between depressed patient status and drinking to cope. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Prospective relations between bulimic pathology, depression, and substance abuse: Unpacking comorbidity in adolescent girls": Correction to Stice et al. (2004).

Reports an error in "Prospective Relations Between Bulimic Pathology, Depression, and Substance Abuse: Unpacking Comorbidity in Adolescent Girls" by Eric Stice, Emily M. Burton and Heather Shaw (Journal of Consulting and Clinical Psychology, 2004[Feb], Vol 72[1], 62-71). The findings of Leon, Fulkerson, Perry, Keel, and Klump ("Three to four year prospective evaluation of personality and behavioral risk factors for later disordered eating in adolescent girls and boys," Journal of Youth and Adolescence, 1999, Vol. 28, No. 2, pp. 181-196), cited on page 62, were incorrectly reported. Leon et al. (1999) found that the latent variable of negative affect/attitudes determined at study entrance significantly correlated with final year eating disorder risk score when conducted with the full sample and when removing Time 1 high eating disorder risk subjects. This latent variable consisted of the GBI Depression, MPQ Negative Emotionality, EDI Ineffectiveness, EDI Interoceptive Awareness, and EDI Body Dissatisfaction scales. A subsequent univariate analysis of Time 1 Negative Emotionality scale score on Time 3 eating disorder risk, adjusting for initial eating disorder risk score, showed a nonsignificant effect size (Stice, E. [2002]. Risk and maintenance factors for eating pathology: A meta-analytic review. Psychological Bulletin, 128, 825-848). (The following abstract of the original article appeared in record 2004-10364-006.) To elucidate the processes that contribute to the comorbidity between bulimic pathology, depression, and substance abuse, the authors tested the temporal relations between these disturbances with prospective data from adolescent girls (N = 496). Multivariate analyses indicated that depressive symptoms predicted onset of bulimic pathology but not of substance abuse, bulimic symptoms predicted onset of depression but not of substance abuse, and substance abuse symptoms predicted onset of depression but not of bulimic pathology. Results suggest that the comorbidity arises because certain disorders are risk factors for the other disorders. Findings also provide support for select etiologic theories and further establish the clinical significance of these conditions by showing that they increase risk for onset of other psychiatric disturbances.
