The Social Sciences , 2013,
Abstract: Many nurses in the hospitals suggest that performing some reformations is required in the management programs of their own places of research. This study aims to describe and analyze the common measures as well as the life experiences among the nurses working at the educational and therapeutic centers. This study is of phenomenological hermeneutic type. The participants were from across the Iran and included 15 nurses, 4 of whom were middle managers of nursing with the clinical experience of patient care. In this study, the data were collected through deep and nonstructural interviews with the nurses. The analysis of information was carried out hermeneutically using the Diekelmann’s seven-stage method. Three basic themes showing the values and concepts of management in particular and consequently a pattern expressing its belonging to the themes were revealed as "adaptation with managerial issues, organizational, individual and professional values for the achievement of nursing human care" considering the performance of a clinical nurse. Furthermore, the findings of this study indicated that the managerial issues in the hospital environment such as the manager’s behavior and managerial approaches, structure and environment of caring, equipment, values and personal expectations of the nurse, organization, society and profession have an inseparable connection in patient care and are interdependent. The analysis and discussion of how these issues are related to each other help us develop our understanding of the way the adaptation of management issues can be effective in the improvement and removal of the obstacles in performing human care in the clinical research of nursing. The improvement and removal of obstacles refers to the methods with the help of which the manager can make an attempt to consider and provide whatever, the nurses needs and develop and enhance the nursing workforce so that they could perform their caring roles. This study reveals those experiences which are mainly required to care for patients, suggesting that their importance be maintained in the health care systems and develop more than ever.

Research Journal of Biological Sciences , 2012,
Abstract: Admission to an intensive care unit is recognized as an extremely stressful experience for both patients and their families. Also, the responses of nurses to visitors in ICU are different and they behave in different ways. The reasons of these behaviors based on some problems that visitors cause for patients and unit managing. However, such belief about open visiting can affect the quality of nursing care specially its spiritual aspects. At present, family visiting policy at intensive care units contains more limitations. By performing this study we temporarily changed visiting policy from outside and beyond the window to presence of family beside patient in own unit. The aim of this study was to analyze the effect of open ICU visiting on nurses and family's beliefs about nursing care. A semi-experimental study was designed. Because of the opposition to changing visiting policy at wide level, sample was contained 14 employed nurses at intensive care unit from educational hospital in Tabriz which each completed one self-structured questionnaire. Questionnaire was developed by using likert scale with 28 questions about personal and social factors of nurses' beliefs about changing visiting policy from restricted to open by using the theory of reasoned action of Ajzen and Fishbein and its validity and reliability was calculated. Results showed that before changing in visiting policy nurses' beliefs was negative. Based on maximum score = 4 mean of scores was 76.71±6.31 and after open visiting was 79.64±5.94. Difference between scores distribution of nurses' beliefs before and after changing visiting policy was meaningful by using Wilkacson test (p = 0.038). Comparing nurses' beliefs score with individual factors, though was not meaningful statistically in general, but nurses' beliefs about the role of family presence in supporting patient, decreasing patients anxiety and hastening patient recovery, obtained higher score after open visiting (57.1, 85.7, 92.8). According to study findings, predominant factors in nurse's beliefs were social factors specially colleagues, supervisors roles, unit policies and managers.

GABAb Receptor Antagonist (CGP35348) Improves Testosterone Induced Spatial Acquisition Impairment in Adult Male Rat  [PDF]
Pourang Shahrzad, Naghdi Nasser
Journal of Behavioral and Brain Science (JBBS) , 2015, DOI: 10.4236/jbbs.2015.511047
Abstract: The high density of the androgen receptors in fundamental centers of learning and memory, such as hippocampus, shows that there must be some relationship between the androgen receptors and cognitive aspects. On the other hand, Gama Amino Butric Acid (GABA) plays a controlling role in the balance of excitability and inhibitory states in the cortex and hippocampus; a number of reports suggest that removal of the influence of inhibitory GABA receptors lead to memory enhancement and conversely the activation lead to memory inhibition. Sex steroids can rapidly influence neural activity by increasing the binding affinity of neurotransmitters such as GABAergic. To determine the effect of Testosterone on learning and memory in CA1 region of hippocampus, male albino Wistar rats (200 - 250 g) are bilaterally cannulated into CA1 of hippocampus then different doses of Testosterone enanthate or CGP35348 are injected through the cannulae for assessing of acquisition, consolidation and retrieval in a single-day testing protocol of Morris water maze task. After hippocampal microinjection with Testosterone (T), acquisition is significantly impaired, while after treatment with CGP35348, acquisition impairment caused by T can be significantly improved. Also T and CGP35348 have no significant effect on consolidation and retrieval stages of spatial memory. These results suggest that CGP35348 may have therapeutic value in the treatment of Testosterone-induced acquisition impairment.
Some Instances of Homomesy Among Ideals of Posets

Mathematics , 2014,
Abstract: Given a permutation $\tau$ defined on a set of combinatorial objects $S$, together with some statistic $f:S\rightarrow \mathbb{R}$, we say that the triple $\langle S, \tau,f \rangle$ exhibits homomesy if $f$ has the same average along all orbits of $\tau$ in $S$. This phenomenon was noticed by Panyushev (2007) and later studied, named and extended by Propp and Roby (2013). After Propp and Roby's paper, homomesy has got a lot of attention and a number of mathematicians are intrigued by it. While seeming ubiquitous, homomesy is often surprisingly non-trivial to prove. Propp and Roby studied homomesy in the set of ideals in the product of two chains, with two well known permutations, rowmotion and promotion, the statistic being the size of the ideal. In this paper we extend their results to generalized rowmotion and promotion together with a wider class of statistics in product of two chains . Moreover, we derive some homomesy results in posets of type A and B. We believe that the framework that we set up can be used to prove similar results in wider classes of posets.

The aim of the present work is to evaluate the putative antidepressant-like effects of pomegranate fruit extract including seeds (PFE) on the performance of male mice in the forced swimming test (FST), after acute administration, after short-term treatment (7 days) and, after repeated administration in a 24-h period (24, 12 and 1 h before swimming test). A single dose (20 ml/kg p.o.) of PFE, in male mice provoked a significant reduction of the immobility time. Such effect was also observed with short-term treatment (7 days) with doses of 1 and 10 ml/kg/day of PFE. Moreover, it was noted that there were important differences in the onset of the antidepressant-like effect in the FST, depending on the modality of treatment with PFE. Both efficacy and potency were higher when repeated administration of PFE was used, and surprisingly the dose of 10 ml/kg (24, 12 and 1 h before swimming test) was as effective as Fluoxetine. In the same way, the short term administration (7 days) improved significantly efficacy and potency of the PFE in comparison to a single dose treatment. These results indicate an antidepressant-like profile of action for PFE which deserves further research.

Higher Education Studies , 2011, DOI: 10.5539/hes.v1n1p27
Abstract: Following the innovations in language teaching and learning, metaphor analysis as an indirect tool of delving into individuals’ beliefs has been utilized in this study to explore the use of metaphor to express the various perspectives of university students about the process of learning and teaching. In fact, this research intends to examine the metaphors produced by Iranian MA students about learning and teaching both in ideal and current situations. Using the Iranian contexts of education, this study aimed at: first, collecting the metaphors the students created by using the prompts “A university student is/should be like a...” and “A university professor is/should be like a...”, and second, identifying and analyzing the metaphors. The results demonstrated that MA university students have different conceptions of learning and teaching, wishing to form the bedrock of their teaching and learning paradigm based on situative learning concepts.
An implementation of TPB method for learning important factors influencing knowledge sharing
Shahrzad Karampour,Mojtaba Bojarpour
Management Science Letters , 2012,
Abstract: Knowledge management incorporates the systematic management of vital knowledge resources and the associated processes of creating, organizing, gathering, utilizing, diffusion and exploiting data. A key challenge emerging is learn to encourage knowledge sharing (KS) within firms because knowledge is an organization’s intellectual capital and plays an important role in gaining a competitive advantage. Isolated initiatives for promoting KS and team collaboration without taking into consideration the limitations and constraints of KS can halt any further development in the KM culture of an operation. In this paper, in addition to individual and social factors, an effect of individual perception, which is an important factor for any behavior, is studied. We first identify effective factors in KS behavior through the theory of planned behavior, six factors of trust, knowledge power, organizational motivation, organizational culture, IT and Communities of Practice (COP) as effective factors in three categories of behavioral beliefs, subjective norms and perceived behaviors are analyzed for an Iranian research center. The results of this research helps develop KS behavior and enhance performance and creativity of research in this center.
