恋情嫉妒倾向及其影响因素和影响作用的研究_恋情嫉妒倾向与自尊、社会比较偏好及嫉妒情绪反应之间的关系

As a well-related concept with close relationship, dispositional romantic jealousy (worrying about the romantic relationship will decrease or be threatened because of the rival) is accepted more and more attention. As the first system study on romantic jealousy under Chinese culture, this study use the combinative methods of questionnaire survey and provided situation-imagine design to study the dispositional romantic jealousy and get some conclusions. 1、The structure of the dispositional romantic jealousy in Chinese undergraduate students consist of three factors: suspicion , exclusivity and dependency . The scale of romantic jealousy has good reliability and validity. 2、The dispositional romantic jealousy can well predict the love attitudes and love experiences. The three factors respectively have different relationship with the love attitudes and love experiences. 3、Comparing with the high self-esteem samples, low self-esteem (include explicit self-esteem, and special implicit self-esteem) samples express more dispositional romantic jealousy among some of the three aspects: suspicion , exclusivity and dependency. 4、Those who get high scores on Scale of Social Comparison Orientation have far more remarkable dispositional romantic jealousy than those who get low scores, the difference exits in three factors: suspicion , exclusivity and dependency. 5、The result of SEM tells us that explicit self-esteem and special implicit self-esteem can negetivly predict some of the three factors of the dispositional romantic jealousy. And special implicit self-esteem also can predict the jealous emotional reaction .Social comparison orientation can predict all three factors of the disposition. And all three factors can positively predict jealous emotional reaction. These findings help us identify the structure of the dispositional romantic jealousy and know more about the influence factors of dispositional romantic jealousy. So we can provide an academic reference on the prevention and intervention of the conflicts among marriage and love relationships.

交易型领导的结构和作用机制研究

The Multifactor Leadership theory developed by Bass (1985) has become the new paradigm of leadership research. The empirical results of the effectiveness of transformational and transactional leadership in the literature, however, are not consentient. Researchers in China found the different structure of transformational leadership, but have not developed the transactional leadership. This study attempts to investigate three key questions in the unique Chinese socio-economic context: 1) what is the structure of transactional leadership in China? 2) What are the differences between western countries and China? And 3) what is the relationship between the transformational and transactional leadership mechanism? This study examines data collected from 3,500 participants, using Explored Factor Analysis (EFA), Confirmed Factor Analysis (CFA), Hierarchical Regression Analyses, partial correlations and other statistics methods. The major finings are listed as follows： Firstly, inductive methods was used to explore the structure of transactional leadership and the result show that transactional leadership is a four dimensions structure which includes contingent reward, contingent punishment , process control and anticipated investment. Reliability analysis, item analysis, EFA and CFA show the reliability and validity of the transactional leadership questionnaire we designed is good enough, the design of the item is effectively and properly. Contrast to other researches, anticipated investment emphasis on the leader’s recessive investment for subordinate, and this kind of transaction is quite special under the Chinese culture. While the content of the contingent reward with the contingent punishment is wider than the contingent reward in the western country, and the process control is wider than the management by exception and including goal setting and the management during the process. Secondly, hierarchical regression analyses showed that transformational and transactional leadership were significant positively related with in-role performance, extra-role performance, satisfaction and leadership effectiveness while negatively related to intention to leave. The effects of transactional and transformational leadership are different. Transactional leadership could significantly predict intention to leave controlling for transformational leadership, while transformational leadership could significantly predict in-role performance, extra-role performance, satisfaction and leadership effectiveness controlling for transactional leadership. Thirdly, the income level and the rank of subordinates are the moderators between the transformational, transactional leadership and leadership effectiveness. The leadership effectiveness of transactional leadership would decrease as the rank of subordinates increased, while the leadership effectiveness of transformational leadership would increase as the rank of subordinates increased. Transactional leadership is positively related to the effectiveness when the level of the subordinate income is low, but negatively related to the effectiveness when the level of the subordinate income is high. However the income level of the subordinate could not influence the leadership effectiveness of transformational leadership.

植入式广告与普通插播广告的效果比较及其影响因素

Brand placement is to present the information of products and brands through certain entertainments and non-commercial areas. Since 1990's, brand placement has become a major way of spreading advertisement and a new growing point of the global advertising market. In china, it is easily seen from spring festival evening gala of CCTV to all kinds of movie and TV shows, and is thus interested by many brand owners, advertisers and communication researchers. Since 2006, the people in the media circles have begin to take full care of the study of the brand placement. In general, there is still certain distance between the theoretical studies and the reality. It's a general problem over the world and is especially true for China as this was just a new idea. As the biggest global economic entity, China is the most potential and powerful market, thus the market of the brand placement will be huge. To push its development, it's then crucial to have theoretical studies on it. Many questions have not been explained yet in this area, mostly essential is to ask what kind of advantage it acquires compared with the traditional advertisement, if there is, how does such advantage show? What kind of factors influents the market effect of the brand placement? All these questions are not answered yet. Also it's well-known that a successful advertisement relies heavily on the understanding of the culture. Thus a specific thing to deal with is to study the effects according to the Chinese culture, which can make constructive suggestion to the whole industry. Our research is to compare the effects between the brand placement with the ordinary media advertisements, discuss its possible influences, and try to make certain suggestions to the future running and development. Our research obtains the following results by using the movie and advertisement in reality: (1) Like ordinary media ad’s, brand placement can improve the brand recognition of the audience significantly. (2) The ordinary ad's make the people easier to remember them than brand placement, while not too much difference in the brand recognition. (3) The brand placement has a significant 'emotional shifting' effect, i.e. the more positive to the movie, the more you love the built-in brand. (4) It is an important factor that how much brand information is involved in the movie; while how much the plot is involved has great impact on the 'emotional shifting' effect. (5) The familiarity is a great factor for the ad's, it's obvious that the popular products get way better effects through brand replacement. (6) An effective way is to choose those positive, interesting and eye-catching movies and TV shows as carriers of the brand and to use it as natural as possible.

不确定性类型对概率表达和概率判断的影响

The present research firstly reviewed the experimental literature on probability expression and probability judgment, hypothesizing that individuals’ preference of probability expressions (verbal probability vs. numerical probability) and tendency for overextremity in probability judgment might differ with respect to different types of uncertainty. Five studies were conducted to test this hypothesis. In Study 1, questionnaires were used to explore the communication preference among Chinese-speaking people. Study 2 adapted the View of Uncertainty Questionnaire to explore the difference of verbal answers to three kinds of uncertainty. Study 3 and Study 4 used methods of the paper-and-pencil questionnaire and the laboratory experiment, respectively, to test the effects of uncertainty types on the preference of probability expressions and on the tendency for over-extreme probability judgment. Finally, Study 5 focused on individuals’ preference of probability expressions under various kinds of scenarios. The results were as follows: 1. The Communication Model Preference paradox phenomenon appears to be even more pronounced in the Chinese culture than in American English cultural settings. 2. The Chinese prefer more verbal probability expressions when communicating uncertainty in a weather-forecasting context than in a general context. 3. Sample groups with lower level of westernization tend to give more extreme answers and less probabilistic answers. 4. Types of uncertainty did have effects on individuals’ tendency for over-extreme probability judgment: under a traditional probability judgment task, people tend to be more over-extreme on internal uncertainty events than on external uncertainty events; however, this result is reversed under a gambling task. 5. Individuals’ preference for verbal probability expressions is more salient on internal uncertain events than on external uncertain events.

中小学生欺负行为及其主要影响因素研究

The present paper studied the school bullying and the primary impact factors, for understanding the nature of bullying, and providing measures and references to the elimination and controlling of school bullying. Primarily with methods of questionnaires and psychometrics, combined with case study and interviews, the following findings were found: in Chinese culture, bullying is a behavior intentionally causing harm to the weaker or weakers. There were 5 types of bullying-physical, social exclusion, threat, breakage and verbal. In Chinese schools the occurrence of bullying had regular patterns. The factor that impact children's bullying behavior was personality traits, interpersonal techniques, family atmosphere, education and upbringing styles. In personality traits, bullies tended to be more extroversive, impulsive, obstinate, obdurate and lack of sympathy. Victims tended to be more introversive, self-restrained, lack of confidence, lonely, anxious and depressive. Both of them expressed more mental problem tendencies than normal children did. When confronted with interpersonal conflicts, they used little problem solving strategies. Bullies had more extroverted emotional responses, and victims had more social support strategies. In the light of family influence, bullies were relatively superior in family's social economic conditions. But their parents had little time and energy spent on them. They tended to be punitive, and had indulgent, reject or despotic upbringing styles. The role of victim might be related to the disadvantage of family's social economic status. Their parents had the tendency of spoiling and overindulgence. The research concluded that in different cultures the connotation of bullying was not homogenous. The occurrence of school bullying had regular patterns. Bullying behavior was primarily influenced by the personality traits of both bullies and victims, the coping strategies of interpersonal conflicts, family's social economic status, parents' basic emotional attitudes, ways of educating, punitive tendencies and school atmosphere. The occurrence of bullying behavior was the result of the combined process of past experience, behavior habits, personality traits, cognitive evaluation, certain evocative clues and the environment conditions. It reminded that quality education and mental health education in schools was essential. Strengthening basic social skill training in school, creating positive family atmosphere, having more communications between schools and families and implementing strict regulations against bullying was essential to interfere and eliminate the school bullying.

心理干预对癌症病人生活质量和免疫功能作用的研究

A set of tools of clinical psychological intervention for cancer patients had been composed for the first time in the form of a manual with three tapes and some pictures. The cancer patients during chemotherapy were treated by psychological intervention via the tools in group and individual therapy. QLQ-C30, POMS-SF and DWI-CI were first recommended and used as indicators for measuring the results of QoL, emotion and coping method in cancer patients in Chinese mainland. NK cell activity and IgG、IgM, IgA were used to measure the immune function. 120 cancer chemotherapy patients were randomly assigned to one of four conditions formed by a 2 (pre-chemotherapy and post-chemotherapy) *2 (experimental and control group) factorial design. The effect of psychological intervention on quality of life and immune function for cancer patients was investigated as well as the mediate role of coping method and personality and their factors. The efficiency of the tools was verified. The major conclusive results drawn out from the study were: 1. After treated by psychological intervention for three months, the status of quality of life and the symptoms of the patients during the chemotherapy was improved accompanying with the increase of immune parameters, especially the NK cell activity. The influential way of the factors, which effected on the effect of psychological intervention on the quality of life, immune parameters and coping methods, was synthetic. There was obvious mutual effects among the factors. 2. The patients of experimental group used more the active behavior, more the active cognition and less the avoidance coping method than those in control group. 3. The results of measurement showed that the personality of the caner patients was of obvious concealing and hiding. 4. Quality of Life Questionnaire-Core 30(QLQ-C30) was suitable for the cancer patients with great efficiency in Chinese mainland although the scale of SF needed to be revised in the light of Chinese culture.

Primary culture and characteristic morphologies of medulla terminalis neurons in the eyestalks of Chinese shrimp, Fenneropenaeus chinensis

A method for culturing medulla terminalis (MT) neurons in the eyestalk of Chinese shrimp, Fenneropenaeus chinensis, was first established. The neurons showed immediate outgrowth in the culture medium supplemented with glutamine, glucose and antibiotics. The cells grew for about 2-7 days and then sustained for a week or more. At least six types of neurons were distinguished on the basis of size and form of soma and outgrowth pattern of cells. (C) 2003 Elsevier Science B.V. All rights reserved.

Stocking models of Chinese mitten crab (Eriocheir japonica sinensis) in Yangtze lakes

The fanning of Chinese mitten crab, a quality aquatic product in China and neighbouring Asian countries, has been developing rapidly in China since last decade. It reached a total yield of 3.4 X 10(5) tonnes in 2002. Due to the successive over-stocking year after year, many lakes in the mid-lower Yangtze Basin, the main farming area, are under deterioration, leading to a reduction of crab yield and quality, and, subsequently, a loss of fanning profits. Aiming at a normal development of crab culture and the sustainable use of lakes, an annual investigation dealing with lake environmental factors in relation to stocked crab populations was carried out at 20 farms in 4 lakes. The results show that the submersed macrophyte biomass (B-Mac) is the key factor affecting annual crab yield (CY). Using the ratio of Secchi depth to mean depth (Z(SD)/Z(M)), an easily measured parameter closely correlated to BMac, as driving variable, 10 regression models of maximal crab yields were generated (r(2) ranging 0.49-0.81). Based on the theory of MSY (Maximum Sustainable Yield), in combination with body-weight (BW) and recapture rate (RR) of adult crabs, a general optimal stocking model was eventually formulated. All models are simple and easy to operate. Comments on their applications and prospects are given in brief. (c) 2006 Elsevier B.V. All rights reserved.

Effects of 2,3,7,8-TCDD and benzo[a]pyrene on modulating vitellogenin expression in primary culture of crucian carp (Carassius auratus) hepatocytes

Vitellogenin (Vtg) is the precursor of yolk protein. Its expression and secretion are estrogen-regulated and are crucial for oocyte maturation. An in vitro xenoestrogen screening model was established by measuring Vtg induction in cultured primary hepatocytes from crucian carp. Vtg production was detected by biotin-avidin sandwich ELISA method while Vtg and cytochrome P4501A1 (CYP1A1) mRNA induction were measured by semi- quantitative PCR-primer dropping technique. Vtg and Vtg mRNA were dose-dependently induced by diethylstilbestrol (DES, 0.2-200 ng/mL) in hepatocytes of crucian carp. Co-treatment of the DES-induced hepatocytes with either 2,3,7,8-TCDD (TCDD, 0.1-4 pg/mL) or benzo[a]pyrene (B[a]P, 5-1000 ng/mL) resulted in a reduction of Vtg production and an increment of CYP1A1 mRNA expression both in a dose dependent manner, indicating the anti-estrogenic effects of the compounds. However, at lower tested concentrations, TCDD (0.1, 0.2 pg/mL), B[a]P (5 ng/mL) seemed to have a potentiating effect on Vtg expression and secretion, although by their own these compounds had no observable estrogenic effect on Vtg induction. Tamoxifen (a selective estrogen receptor modulators, 1 nmol/L-1 mumol/L), and P-naphtho-flavone (beta-NF, an aryl hydrocarbon receptor inducing compounds, 2.5-1000 ng/mL) also were employed to study the possible interactions in DES-induced Vtg expression. In co-treatment of the DES-induced hepatocytes with beta-NF or tamoxifen, the decrease in Vtg production did parallel induction of CYP1A1 for beta-NF, but tamoxifen inhibited Vtg induction did not parallel induced CYP1A1 expression in all test concentrations. On the contrary, it was found that in co-treatment of the TCDD-induced hepatocytes with DES, TCDD induced CYP1A1 mRNA production was inhibited by DES also. These results implicated a possible cross talk between estrogen receptor- and aryl hydrocarbon receptor-mediated pathways in the hepatocytes.

Detection of hepatotoxic Microcystis strains by PCR with intact cells from both culture and environmental samples

Microcystins are small hepatotoxic peptides produced by a number of cyanobacteria. They are synthesized non-ribosomally by multifunctional enzyme complex synthetases encoded by the mcy genes. Primers deduced from mcy genes were designed to discriminate between toxic microcystin-producing strains and non-toxic strains. Thus, PCR-mediated detection of mcy genes could be a simple and efficient means to identify potentially harmful genotypes among cyanobacterial populations in bodies of water. We surveyed the distribution of the mcyB gene in different Microcystis strains isolated from Chinese bodies of water and confirmed that PCR can be reliably used to identify toxic strains. By omitting any DNA purification steps, the modified PCR protocol can greatly simplify the process. Cyanobacterial cells enriched from cultures, field samples, or even sediment samples could be used in the PCR assay. This method proved sensitive enough to detect mcyB genes in samples with less than 2,000 Microcystis cells per ml. Its accuracy, specificity and applicability were confirmed by sequencing selected DNA amplicons, as well as by HPLC, ELISA and mouse bioassay as controls for toxin production of every strain used.

Kinetics of alkaline phosphatase in lake sediment associated with cage culture of Oreochromis niloticus

Variations in kinetics of alkaline phosphatase occurring in different sites of sediment associated with cage culture of Oreochromis niloticus in a shallow Chinese freshwater lake (Lake Donghu) were described. In addition, the kinetic parameters of each 2.5-cm stratum in the sediment from the surface down to 37.5 cm were analyzed. Horizontally, the V-max values of alkaline phosphatase in surface sediments increased markedly at sites immediately under and adjacent to the cage that would be subjected to the deposition of fish feces. Peak V-max values in the top 5 cm of the sediment under the cage were also observed relative to their deeper control. After a treatment where the fish feces were added over 12 days, the sediment in deeper layer exhibited a significantly higher V-max value, thereby corroborating the relationship between V-max values of alkaline phosphatase and fish feces in sediments. The fish feces exhibited a remarkable alkaline phosphatase activity (APA). Thus, it is indeed a source of the enzyme. Effects of the fish feces were dose- and time-dependent. The V-max values in sediments were always stimulated, but the K-m values showed much more variability. (C) 2001 Elsevier Science B.V. All rights reserved.

In vitro culture of embryonic hearts from guppy fish (Poecilia reticulata)

Forty embryonic hearts were taken out by anatomical needle from denuded embryos of the ovoviviparity guppy fish that were dechorioned by mechanic method or by trypsin digestion, and were in vitro cultured. In the cultured hearts, 80% have maintained beating in vitro for 4 weeks, and the longest record for beating was 142 d. Owing to fish embryo transparency, beating frequency and blood color changes are easily viewed from the embryonic hearts under a dissecting microscope. The current study established the in vitro culture method of embryonic hearts in guppy fish, which can be used as a model for the study of heart and cardiovascular system in vertebrates.
