The present paper is an attempt to explore the impact of Karl Popper’s ideas on the views of a number of intellectual groups in post‐revolutionary Iran. Throughout the text, we have tried to make use of original sources and our own personal experiences. The upshot of the arguments of the paper is that the Viennese philosopher has made a long‐lasting impression on the intellectual scene of present‐day Iran in that even those socio‐political groups which are not in favour of his ideas, especially his model of critical rationalism, have felt the urgent need to make themselves familiar with them. Moreover, many of Popper’s ideas have directly or indirectly influenced the thinking of the decision‐makers in Iran since 1978.  相似文献

Using a questionnaire adapted from Arnett and Padilla‐Walker (2015), the authors examined the concept of adulthood among 366 Iranian emerging adults ages 17 to 29. Results suggested that the concept and criteria of adulthood are influenced by the cultural context. Implications for practice and recommendations for future research are discussed.  相似文献

Social media usage has been popular for the last decade. Individuals use their social media environments for various reasons such as to socialize, play games, have fun and share posts. Overuse of these environments may lead to negative psychological and behavioral consequences for individuals. Additionally, it increases the worries about potential addicted/problematic use of social media. In this study, it is aimed to determine the level of problematic social media usage of participants who are active social media users and to analyze the relationships between problematic social media usage and various personal characteristics and social variables. Study in relational screening model is carried out with the participation of 580 volunteers. Partial least squares (PLS) structural equation modeling is used to analyze the data obtained through various scale according to the research model. The structural equation modeling analysis shows that there is a significant relationship between problematic social media usage and the daily time of social media usage, the use of frequency of social media for recognition, publicity, communication/interaction and education, loneliness, and social anxiety. The variable which shows higher correlation between problematic social media usage is social anxiety.  相似文献

Despite a comprehensive reproductive health program there is little sex education available in Iran. In this article we present results of a study conducted to identify content area for a proposed sex education program for married Iranian women. Twenty-one married female clients (23–45 years) and 18 reproductive health providers, recruited from urban health clinics in Tehran using non-probability sampling, participated in four focus group discussions. Sexual health information needs related to reproductive tract and sexually transmitted infections, “acceptability” of certain sexual practices such as oral and anal intercourse, and the sexual response cycles and physiology of men and women. Women’s sexual concerns related to communication, incompatibility of sexual interests and desire, and their ability to maintain a strong marriage. Two themes cut across women’s responses to all questions: modesty and maintaining a strong marriage. Results contributed to the design of a sex education program that addressed the specific information needs and concerns of Iranian women.  相似文献

The purpose of this study was to assess the mediating effect of self-efficacy on the relationship between identity styles and academic achievement. Four-hundred high school students (200 male, 200 female) who were selected through cluster random sampling, completed the Revised Identity Styles Inventory (ISI, 6G) and Morgan-Jink Student Efficacy Scales (MJSES). Path analysis was used to analyze the data. In general, the results indicated that informational identity style had a positive direct impact on academic achievement, while diffuse/avoidance identity style had a negative effect on academic achievement. Data also suggested that informational and normative identity style had a positive influence on academic achievement through the mediation of academic self-efficacy.

Body-weight maintenance is required in a variety of behavioral and physiological studies. A PC-based animal-weighing system is described; it features automated data collection and allows for accurate control of body weight in test animals via manipulation of food intake. Major system components are a PC XT-compatible computer, Lotus 1-2-3 and National Instruments Measure software, and a digital electronic balance. The system is controlled by Lotus macros, which present menus to the user. Menus provide for the basic operations of the system, including establishing new data files, collecting weight data, printing, and transferring files to a laboratory minicomputer. The optional weight-maintenance algorithm calculates the amount of food necessary to maintain target body weights. Some important aspects of this algorithm, including maintenance-feeding and gain parameters, can be manipulated to reduce weight oscillation in test animals or to accommodate the maintenance of body weight of different animal species. The system facilitates acquisition and recording of weight data, minimizes the frequency of error, and reduces variability both within and across animals when body-weight maintenance is required.  相似文献

Recent research has indicated that anxious adult and child patients and high trait-anxious adults selectively shift attention toward threatening stimuli. The present study extends this research and investigates the content-specificity of the effects in clinically anxious and mixed anxious–depressed children and adolescents. Twenty four generally anxious patients, aged 9 to 18, 19 mixed anxious–depressed patients, and 24 normal controls were comparable with respect to age, sex, verbal IQ, and vocabulary level. The participants carried out an attentional deployment task in which probe detection latency data were used to determine the distribution of visual attention for threat-related and depression-related material. The results showed that clinically anxious children, relative to controls, selectively allocated processing resources toward threat stimuli. However, mixed anxious–depressed children, relative to controls, did not show any attentional bias towards either threat- or depression-related stimuli. Preliminary data on age and gender differences are also presented. The results of this study are discussed in the light of previous research.  相似文献

躯体性和心理性应激对大鼠血浆皮质酮变化的影响   总被引:23,自引:1,他引:22  
本实验以血浆皮质酮分泌量为大鼠应激反应指标。实验分三阶段进行:Ⅰ期.适应(第1~7天),在此期所有动物对环境及实验盒适应性训练。Ⅱ期.心理性应激的形成(第8~14天).随机分三组进行:对照(C)组仅给不规则光;规则光(R)组给光后再于尾部施电刺激,光与电刺激间隔恒定;不规则光(Ⅰ)组给光和电刺激,但两者间隔随机。C、R、I三组所接受的光刺激量相等,R、I组所接受的电刺激量相等。Ⅲ期.心理性应激的记忆(第15天).此期各组电刺激均撤除,余同第Ⅱ期。结果显示,在Ⅱ期末及Ⅲ期,R、I组血浆皮质酮均明显高于C组,I组高于R组。  相似文献

The effects of dopaminergic drugs on morphine state-dependent memory of passive avoidance task were examined in mice. Pre-training administration of morphine (5mg/kg) led to state-dependent learning with impaired memory retrieval on the test day which was reversed by pre-test administration of the same dose of the opiate. The pre-test intracerebroventricular (i.c.v.) administration of the dopamine D1 receptor agonist (SKF38393), dopamine D2 receptor agonist (quinpirole) and dopamine D2 receptor antagonist (sulpiride) not only reversed the effect of pre-training morphine treatment, but also increased this action of the drug. Furthermore, the pre-test i.c.v. administration of dopamine D1 receptor antagonist (SCH23390) prevented the restoration of memory by morphine. In conclusion, the morphine-induced recovery of memory, on the test day, seems to be induced, at least in part, through dopamine receptors.  相似文献
