The Relationship between EQ & Constructive and Non-Constructive Problem Solving Styles among Payame Noor University's students of Abadan in the year 2014
The objective of the present study is considering the relationship between EQ & constructive and non-constructive problem solving styles among students. The applied methodology is cross-correlation method. The statistical population in this study is all the educational sciences' students of Payame Noor university of Abadan in the year 2014 and the sampling is taken totally randomly and voluntary. Two surveys of EQ which proposed by Siryashring (1988) have used in this study that contain 33 questions. This study will measure 5 components of emotional intelligence: Self-awareness, self-control, self-motivation, social awareness and social skills. In addition the problem solving styles' survey that proposed by Velang (1996) has been applied that has made in two stages and has 24 questions, 12 items measure the problem-oriented style and rest of them measure the excitement-orientation. According to Cronbach's alpha the reliability coefficient of EQ is reported about 0.84. The validity of 0.63 is confirmed in Shirng's test of EQ. reliability coefficient of solving problem style is reported about 87%.Either reliability coefficient or factor content are confirmed by the faculty. Data analysis is done in two level of descriptive statistical (frequencies, percentages mean) and inferential statistics (Pearson correlation, chi-square test). The obtained results of assumptions show that there is no significant relationship between EQ and constructive problem solving; also there is no significant relationship between EQ and non-constructive problem solving. Moreover there is significant relationship between EQ in creative styles, avoidance and style tendencies. Nevertheless there is no relationship between EQ and distress styles. And the confidence style shows an inverse relationship. Keywords: EQ, Constructive problem solving styles, non- constructive problem solving style

Solvent effects on structural and thermochemical properties of p53 tumor-suppressor gene: a molecular modeling approach in drug design
The p53 tumor-suppressor protein is a cellular phosphoprotein and a negative regulator of cell growth. Most p53 mutations occur in exons 5–8 within the DNA-binding domain. Therefore, p53 can potentially be targeted with novel drugs designed to bind to a mutation and restore its stability or wild-type conformation. For the current study, Hartree–Fock calculations were used to investigate the solvent-induced effects of five different solvent media (acetone, ethanol, methanol, dimethyl sulfoxide, and water) on the thermochemical parameters and relative energies, and on the multinuclear nuclear magnetic resonance shielding tensors of oxygen, nitrogen, and phosphorus nuclei, of GAT. To understand how the solvent affects the mutation region (the “hot spot”) of p53, the relative energies of GAT in selected solvent media were determined. Some biological evidence suggested the structural stabilities of hot spots of GAT have the optimum temperature and solvent type for mutation. All the authors’ findings are in accordance with common biological phenomena. Another important objective of this study was to compare the hydration Gibbs free energies of CUA and GAT in water using two different approaches where the solvent was treated as a continuum of the constant at different levels of Hartree–Fock theory. The Gibbs hydration energy values obtained in water with the polarized continuum model directly applied on the isolated CUA and GAT sequences were compared with those determined from the hydrated models with four, six, and eight water molecule clusters around the hot spots uracil and adenine. The clustered structures of water molecules around the hot spots of GAT (in DNA level) and CUA (in transcriptional level) were found to be energetically favored. The results of this study provide a reliable insight into the nature of mutation processes, which is of utmost importance for the study of biochemical structures, and provide a basis for drug design
A trade-off between productivity and cost for the integrated part quality inspection and preventive maintenance planning under uncertainty
This paper proposes a robust possibilistic and multi-objective mixed-integer linear programming mathematical model to concurrently plan part quality inspection and Preventive Maintenance (PM) activities for a serial multi-stage production system. This system contains the deteriorating stages and faces the uncertainty about estimated cost components and demand amount. The integrated model reaches two significant decisions which are the right time and place for performing the part quality inspection and PM. These decisions are made while the model is to simultaneously optimise the implied system productivity and total cost. To measure the implied system productivity, a new piecewise utility function for the ratio of produced conforming products to input workpieces is developed. A real case study and a numerical example are explored to validate and verify the developed model. The results prove the significance and effectiveness of considering the uncertainty and conflicting practical objectives for the problem
A novel model for the integrated planning of part quality inspection and preventive maintenance in a linear-deteriorating serial multi-stage manufacturing system
This paper presents a mixed-integer linear mathematical programming model for the integrated planning problem of the part quality inspection and preventive maintenance activities in serial multi-stage manufacturing system. The model concurrently determines the right time and place for performing the above-mentioned activities while the production stages are linearly deteriorating. These two decisions are made while the model is to minimize the total cost including the production, maintenance, inspection, scrap, replacement, and the penalty of shipped defective items to customer(s). A numerical example and a real case study are investigated to validate and verify the proposed model. The results show that the determination of inspection locations along a manufacturing line in different periods of time regarding the impact of preventive maintenance activities on defective production probability results in a more efficient manufacturing system
Identifying the Talent Management Components of Faculty Members
Background: Since employing talent management as a system to identify, recruit, train, promote, and retain talented faculty members
to optimize the capabilities of the university to achieve goals seems necessary, the current study aimed to identify the talent
management components of faculty members.
Methods: This qualitative study was conducted on the directors and faculty members of Isfahan University, Isfahan University of
Medical Sciences, and Isfahan University of Technology, Iran. A purposive sampling method was used and semi-structured interviews
conducted to collect data. All interviews were recorded, transcribed, and transferred to a computer using MAXQDA software.
Following this, the data were coded, categorized, and interpreted, and then analyzed using a content analysis method.
Results: After interviewing 18 university directors and faculty members, data pooling, data saturation, and data replication were
performed. Accordingly, 107 codes were extracted from the obtained data and categorized into seven major classes. These were
Defining and identifying talent needs, discovering talent sources, Attracting talents, Developing the potential abilities of talents,
Strategically deploying talents, Retaining talents, and evaluation and alignment of talent management activities.
Conclusions: Based on the results, 7 main classes and 20 subclasses of talent management components of faculty members were
identified. These components are provided in a conceptual model. The evaluation and alignment of talent management activities
are the main factors supporting talent management. Furthermore, dynamic coherence and integrity in identifying, discovering,
attracting, developing, retaining, and effectively using talent, and the alignment of such features with the general strategy of the
university were considered the strengths of the suggested conceptual model.
Keywords: Talent Management, Competencies, Faculty Member
Effect of Dexamethasone on Striatal Neurotransmissions in the Rats Subjected to Parkinson’s Disease Animal Model
Objective(s)The aim of this study was to evaluate the effects of dexamethasone on striatal dopaminergic, glutamatergic and gamma amino butyric acid (GABA) ergic neurotransmission in normal and parkinsonian rats.Materials and MethodsDexamethasone (0.15, 0.30, 0.60 and 0.8 mg/kg) was administered to normal or parkinsonian rats (i.p.) followed by the analysis of the striatal neurotransmitters concentrations. Additionally, the effect of dexamethasone on the damaged Substantia nigra pars compata (SNc) neurons has been investigated. ResultsDexamethasone resulted in decreased level of striatum glutamatergic-GABAergic and enhanced dopaminergic neurotransmission in normal and parkinsonian rats. In addition, acute treatment with dexamethasone did not improve the lesion at all. ConclusionThese findings suggest the new therapeutic mechanism of action for dexamethasone in Parkinson’s disease animal model
A review on optimisation of part quality inspection planning in a multi-stage manufacturing system
In multi-stage manufacturing systems, optimisation of part quality inspection planning (PQIP) problem means to determine the optimal time, place and extent of inspection activities for assessing the significant quality characteristics of products while maximising the system efficiency. An inspection activity is capable of detecting the produced defects partially and accordingly prevents further processing of them in downstream and more importantly avoids them to reach customers. In this paper, the existing researches on the optimisation of the part quality inspection are surveyed from the viewpoint of the considered production system characteristics; the applied modelling approaches and solution methodologies. This review found that although numerous works have been already done on the PQIP, the development of multi-objective optimisation frameworks considering real production constraints under parameters uncertainty is necessary. Also, by the Industry 4.0 trend, the creation of integrated models aiming to plan the inspection, maintenance and production activities simultaneously, seems to be an important potential future research direction
Topical effectiveness of different concentrations of nanosilver solution on Leishmania major lesions in Balb/c mice
Background & objectives: Cutaneous leishmaniasis is an infection caused by protozoan genus Leishmania. Althoughglucantime is commonly used for the treatment of leishmaniasis, it has some side effects including increased liverenzymes and electrocardiogram changes. In addition, the drug is expensive, the injection is painful, and researchshows that resistance of parasite to glucantime is growing in different parts of the world. Therefore, scientists arepaying more attention to develop new drugs such as nanosilver solution. The present study is an attempt toevaluate the in vivo topical effects of different concentrations of nanosilver solution in the treatment of leishmaniasislesions.Methods: In all, 90 female Balb/c mice aged 6–8 wk were infected with 2×106 viable stationary-phase promastigotesin the base of tail. Different concentrations (60, 80, 120, 130 and 2000 ppm) nanosilver solution were used in thepresent study to test the efficacy in the treatment of lesions. Clinical control of the infection trends was conductedweekly for 5 wk by measuring lesion diameter with standard Kulis-Vernieh. Data were analyzed by paired t-test,analysis of variance (ANOVA), and Tukey test.Results: Mean lesion diameter pre- and post-treatment did not significantly differ between different treatmentgroups (p >0.05). Likewise, a significant difference in splenic parasite load was also not observed between differenttreatment groups.Interpretation & conclusion: Based on our results, different concentrations of nanosilver are ineffective in reducingmean sizes of lesions
