Effective Leadership and Culture in Iran: An Empirical Study

On analyse dans cet article les caractéristiques du leadership efficace en Iran, puis on envisage les liens possibles entre ce profil de leadership et les dimensions culturelles du pays. A partir des données fournies par 300 managers provenant de plus de 60 organisations relevant de trois secteurs industriels, on commence par utiliser les dimensions du projet GLOBE pour évaluer la culture iranienne dont les scores sont comparés à ceux d'autres pays. S'appuyant à la fois sur l' emic et l' etic du leadership, les auteurs développent sept dimensions du leadership: encourageant, dictatorial, visionnaire, familial, modeste, loyal et réceptif. Ils soutiennent que certaines de ces dimensions traduisent les aspects universels (ou etic ) du leadership (éncourageant, dictatorial), alors que d'autres procèdent de l' emic , c'est‐à‐dire de la spécificité culturelle du leadership (modeste, familial, loyal). Les résultats sont discutés en terme de positionnement de la culture iranienne entre des entrelacements fondamentaux et des traditions culturelles complexes. On aborde enfin la question des retombées sur les recherches à venir.     

Memory performance in abstinent 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") users

Research with animals and humans has suggested that acute and subacute use of 3,4-methylenedioxymethamphetamine (MDMA "ecstasy") may lead to memory impairment. However, research is limited by (1) low power due to small sample sizes, (2) the possible confound of polydrug use, and (3) the failure to consider intelligence as a covariate. The present study compared the memory performance on the Wechsler Memory Scale-III of 26 abstinent (2-wk. minimum) recreational MDMA users with 26 abstinent (2-wk. minimum) recreational polydrug users. Despite significantly greater polydrug use amongst these MDMA users, no significant group differences in memory were observed. Regression of total lifetime amount of MDMA use also did not predict memory performance after accounting for intelligence. In addition, the length of time since abstinence (at least 2 wk.) was not associated with an increase in memory performance. Greater total lifetime cocaine use, rather than total lifetime MDMA use, was significantly associated with greater decrements in General Memory and Delayed Verbal Memory performance.     

Mental health of medical students: a cross-sectional study in Tehran

Medical students are subject to stress from sources related to medical training in addition to personal problems, resulting in significant mental distress. This study evaluates the scope of the problem in Tehran medical schools and sheds light on some of its associations. Students (604) of medicine from four medical schools in the city of Tehran responded to the Persian version of 28-item General Health Questionnaire (GHQ-28) in conjunction with a data collection sheet asking about age, sex, marital status, current training level, living place, grade point average in previous semester, and perceptions of their financial status. Of 602 students, 40.7% had mental distress (45.7% of female and 36.7% of male students). Distress was associated with being a woman (female to male odds ratio: 1.55) and very poor financial status (OR: 18.0).     

N-Methyl-D-aspartate receptors in the ventral tegmental area are involved in retrieval of inhibitory avoidance memory by nicotine

The interaction of opiate, cholinergic, glutamatergic and (possibly) dopaminergic inputs in the ventral tegmental area (VTA) influencing a learned behavior is certainly a topic of great interest. In the present study, the effect of intra-VTA administration of N-methyl-d-aspartate (NMDA) receptor agents on nicotine's effect in morphine state-dependent learning was investigated. An inhibitory avoidance (IA) task was used for memory assessment in male Wistar rats. Subcutaneous (s.c.) administration of morphine (5 and 7.5mg/kg) immediately after training decreased IA response on the test day, which was reinstated by pre-test administration of the same doses of the opioid; this is known as state-dependency. Moreover, pre-test administration of nicotine (0.2, 0.4 and 0.6 mg/kg, s.c.) also reversed the decrease in IA response because of post-training morphine (5mg/kg). Here, we also show that when infused into the VTA before testing, NMDA (0.01 and 0.1 microg/rat) reverse the post-training morphine effect on memory. In addition, the sub-effective doses of NMDA (0.0001 and 0.001 microg/rat) in combination with a low dose of nicotine (0.1mg/kg) which had no effects by themselves, synergistically improved retrieval of IA memory on the test day. In contrast, pre-test administration of a competitive NMDA receptor antagonist D-AP5 (0.5, 1 and 2 microg/rat) which had no effect alone prevented the nicotine reversal of morphine effect on memory. Our data indicate that NMDA receptors in the VTA are involved in the reversing effect of nicotine on morphine induced state-dependency.     

Remembering the Historical Roots of Remembering the Personal Past

As scholars, remembering the historical past in one's area of study provides a foundation for purposefully pursuing knowledge. As individuals, remembering our personal past provides direction and purpose in everyday life. Taken together, these percepts provide the impetus for the current paper, which traces the contributions of six early pioneers who wrote about how humans remember their personal past. Analysis demonstrates how their historical ideas support current literatures focused on the personal past: reminiscence‐based mental health interventions, the adaptive psychosocial functions of autobiographical remembering, and the construction of identity as a life story. Three future research directions are also briefly presented: the human ability for mental ‘time travel’, a lifespan approach to remembering the personal past, and reflection on one's past as a route to wisdom. Understanding the human phenomenon of remembering the personal past has long‐standing historical roots that continue to stimulate basic and applied research.

The Network Constellation of Personality and Substance Use: Evolution from Early to Late Adolescence

There is a well-established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation-seeking. However, construct-level models of personality may conceal indicator-level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co-Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age-specific associations between personality indicators and substance use. The positive role of the sensation-seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance-specific and age-adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology     

Culture and Gender Representation in Iranian School Textbooks

This study examines the representations of male and female social actors in selected Iranian EFL (English as a Foreign Language) textbooks. It is grounded in Critical Discourse Analysis and uses van Leeuwen’s Social Actor Network Model to analyze social actor representations in the gendered discourses of compulsory heterosexuality. Findings from the analysis show that the representations endorse the discourse of compulsory heterosexuality which is an institutionalized form of social practice in Iran. Three male and three female students were interviewed to find out what they think about these representations. Their responses with regard to whether they think textbooks should also include representations of other forms of sexuality were non-committal and vague. To them LGBT people are the “Other” practicing a form of sexuality that is not normal. Such exclusions could obscure the reality regarding the existence of such gender identities and represent the world in a particular manner.     

Does digital content marketing affect tourism consumer behavior? An extension of technology acceptance model

With the rapidly dramatic environmental change and intensive competition, tourism organisations are required to adopt advanced marketing strategies and techniques. Recently, digital content marketing (DCM) has become one of the most prominent marketing tools that has substantial benefits and influences in different settings and domains. To this end, it is crucial to understand the effect of DCM on consumer behavior within the tourism context. Therefore, this research empirically examines an extended technology acceptance model (TAM) model to investigate and compare the influence of DCM on travel and tourism consumer behavior in two distinct countries in the Middle East and North Africa (MENA) region. A quantitative approach was adopted by collecting surveys from a convenience sample of 285 and 122 participants in Egypt and Oman, respectively. The findings of PLS‐structural equation modelling revealed that the TAM major constructs were good elucidating the attitude and behavior toward using of DCM for tourism purposes. It is also found that perceived enjoyment and perceived convenience are antecedents of customers' attitudes, which in turn, influence their intention and behavior of using DCM to buy or select a certain tourism product/service. The current study contributes to knowledge of DCM literature in the tourism field in general and within the MENA region in particular. It also adds to studies on TAM and digital technologies by extending two critical constructs related to tourism consumer behavior. The practical implications will greatly support tourism marketers and authorities to develop their tourism strategies and marketing activities. Future research can be expanded to study different target groups comprehending region differences.
