Footwear for Gender Recognition

Conventionally, biometrics resources, such as face, gait silhouette, footprint, and pressure, have been utilized in gender recognition systems. However, the acquisition and processing time of these biometrics data makes the analysis difficult. This letter demonstrates for the first time how effective the footwear appearance is for gender recognition as a biometrics resource. A footwear database is also established with reprehensive shoes (footwears). Preliminary experimental results suggest that footwear appearance is a promising resource for gender recognition. Moreover, it also has the potential to be used jointly with other developed biometrics resources to boost performance.

Metabolism of polychaete Neanthes japonica Izuka: relations to temperature, salinity and body weight

Polychaete Neanthes japonica is a species geographically specific in China and Japan with important scientific implication and commercial value. In this study, the relations of body weight, salinity and temperature to oxygen consumption and ammonia excretion of N. japonica were determined. Three different groups in body weight (large: 2.34 +/- 0.36 g, middle: 1.50 +/- 0.21 g and small: 0.62 +/- 0.12 g) were set for all experiments. Results show that the body weight is negatively related to the rates of oxygen consumption and ammonia excretion; and the relationship is significant. The oxygen consumption and ammonia excretion at 24A degrees C decreased at salinity from 5 to 30 and increased above 30, indicating that both lower and higher salinity are adverse and certain degree of salinity stress is necessary for enhancing the energy demand. At salinity 30, rising temperature from 18A degrees C to 30A degrees C, the oxygen consumption increased before 27A degrees C and then decreased. However, the relation of ammonia excretion and temperature seems more complex. Two-way ANOVA shows that salinity, temperature and body weight all have a significant effect on the oxygen consumption and ammonia excretion of the worm. Moreover, interaction between salinity/temperature and body weight is also significant. O:N (oxygen/nitrogen) ratio varies greatly in this case from 5.97 to 463.22, indicating that N. japonica can regulate the type of metabolic substrate against environment changes.

Relations between A-type granites and copper mineralization as exemplified by the Machangqing Cu deposit

This paper deals with the relations between the Machangqing rockbody which corresponds to the A-type granites and porphyry copper mineralization in terms of petrochemistry, trace element geochemistry, fluid inclusion geochemistry and isotope geochemistry. The results show that the Machangqing porphyry copper deposit was formed from the fluid predominated by mag-matic fluid. This kind of ore-forming fluid was just differentiated from the magma responsible for the A-type granites. therefore,as viewed from whereer they contain water or not,the A-type granites can,at least,be divided into two types: water-bearing and water-free.The water-bearing A-type granites can serve as the host ofporphyry copper deposits under certain geological conditions.

中学生自我评价、泛化信任和应对方式及其于心理健康的关系

The aim of this research is to explore the relationships between Self-evaluation, general trust, coping styles and psychological health of secondary school students. Three studies were carried out. A total of 1024 middle school students ranging in age from 11 to 20 years complete SCL-90, secondary school students self-evaluation scale, questionnaire of coping styles and GTS. It is found that: 1. There were three self-evaluation in middle school students: the self-evaluation in study, in human relations and in appearance. 2. The three factors of self-evaluation are all correlated to gender, grade and single children. 3. General trust of secondary school students is no difference in gender, grade and single children. 4. Aside from the negative exterior copied ones, three self-evaluation and general trust significantly predict the other three coping styles. 5. When we control the gender , grade and and the only-child in multiple linear regression, we found that the coping style has more effect on their psychological health than the gender , grade and and the only-child and influencing of negative coping style is highest. 6. Three self-evaluations and general trust have direct influences on psychological health of secondary school students. Taking coping styles as intermediate variables , three self-evaluations and general trust have direct influences on psychological health of secondary school students.

当代大学生消费价值观与消费行为的调查研究——北京大学生中的消费主义倾向及有关影响因素研究

The aim of this study was to investigate consuming values and behaviors in Chinese college students, to detect the factorial structure in consuming values, and to explore possible determinants of those values and their effects on consuming behaviors. A total of 778 students from various universities in Beijing were investigated with questionnaire survey. The main results and conclusions are as follows: (1) College students were basically satisfied with their current life and study conditions in university, and their main pressures or stresses were from their studies. They were highly motivated in the development of their academic and life careers, and also valued the importance of family and having children in the future. About 11% of the students had pressures due to less favorable financial conditions of their families. (2) Five basic consuming values were found among college students, namely, “industrious and thrifty-aimed value”, “status and brand-aimed value”, “personal and unique-oriented value”, “relation-aimed value”, and “autonomous-aimed value”. The “industrious and thrifty-aimed value” stands for the traditional consuming values in the culture, and the “status and brand-aimed value” shows an explicit tendency of consumerism. The other three consuming values had moderate relations with both of the two values. (3) There was a high negative correlation between the first two values, which showed both a general acceptance and the main trend of “industrious and thrifty-aimed value” among the students. The basic “status and brand-aimed value” was shown among 3.3% of the students. (4) The consuming values were significantly correlated with life values, indicating that consuming values could be in consistence with or be determined by basic life values. The “industrious and thrifty-aimed value” and the “autonomous-aimed value” were shown as collectivistic values, while the “status and brand-aimed value” and “relation-aimed value” were shown as individualistic values. (5) Consuming values had significant influences on consuming behaviors. (6) The demographic factors such as financial conditions of parents, children of number in family, urban-rural location of family, gender, age, and campus culture could affect consuming values and consuming behaviors of college students in both direct and indirect ways.

影响大学生学业成绩的四个重要非智力因素

In the present study, 520 questionnaires about general self–efficacy, achievement goal orientation, learning motivation and time management were delivered to university students. The students were randomly chosen from Communication University of China, Central University of Finance and Economics, Capital University of Business and Economics and Shanxi University. 495 responses were valid , in which 225 majoring in liberal arts and 270 majoring in natural sciences. The influences of these four factors on students’ academic achievements were explored. And the gender differences in General self-efficacy, achievement goal orientation, learning motivation and time management were analyzed in the present study too. It was found that: 1) There were gender difference on academic achievements. The scores’ of female students were higher than males’. 2) Significant gender differences were found in four considered factors which indicated that female students got higher scores than male students; 3) There were close relations between the four considered factors and students’ academic achievements. There were also obvious relations among the four factors. 4) University students’ academic achievements could be well predicted by their general self-efficacy, achievement goal orientation, learning motivation and time management.

亲子依恋对大学生人际关系影响的性别效应

Parent-child attachment refers to the emotional bond that forms between parent and child, which has great influences on the child’s interpersonal development. Present study applied both correlation method and secure attachment memory activation method to investigate the “gender relation effects” of parent-child attachment’s influences on college students’ close relationships, general attachment representation, and emotion and social loneliness. The basic hypotheses on “gender relation” were set as: “same-sex” parent-child attachment has more influences on college students’ “same-sex” interpersonal relationships, while “opposite-sex” parent-child attachment has more influences on college students’ “opposite-sex” interpersonal relationships. Major findings includes: 1. There was weak correlation of attachment security between father-child and mother-child relationships. The findings indicated that, among college students, the security of “opposite-sex” parent-child attachment representation is higher to some extent than that of “same-sex” parent-child attachment representation. 2. There were significant correlations between parent-child attachment and college students’ attachment anxiety in close relationships. Major findings indicated that “opposite-sex” parent-child attachment security negatively predicts college students’ attachment anxiety in both “same-sex” and “opposite-sex” close relationships. 3. Gender relation effects were significant in the correlations between parent-child attachment and college students’ level of avoidant attachment representation. “Same-sex” parent-child attachment security positively predicted avoidant attachment level in college students’ “same-sex” close relationships, while “opposite-sex” parent-child attachment security positively predicted avoidant attachment level in “opposite-sex” close relationships. 4. Parent-child attachment security memory activation had significant influences on college students’ general attachment representation, in which gender relation effects indicated that: the memory activation of father-child attachment security significantly increases participants’ security of self-model in general attachment representation to “male others”; while the memory activation of mother-child attachment security significantly increase participants’ security of others-model in general attachment representation to “female others”. 5. For male college students, father-son attachment security negatively predicted their emotion and social loneliness. For female college students, father-daughter attachment security negatively predicted their emotion loneliness, while mother-daughter attachment security negatively predicted their social loneliness. Attachment security memory activation had significant influences on college students’ social loneliness, in which gender relation effects was confirmed in that only father-child attachment security memory activation significantly decreased male participants’ level of social loneliness. The results indicated that gender relation effects are significant in the influences of parent-child attachment on college students’ interpersonal relationship representations, especially when the level of avoidant of attachment in college students’ close relationships was predicted by parent-child attachment representation, and when the memory activation of parent-child attachment influenced college students’ general attachment representation. The present study confirmed to some extent that gender relation consistency exists in attachment representations among different interpersonal relations, and serves as a new model for analysis of gender differences in the research fields. In the present study, however, gender relation effects were not confirmed in all the interpersonal relationship representations, which indicated the complexity in the problems of gender differences in the research fields of close relationships.
