Objective: People who have higher social health can more successfully deal with the challenges and ups and downs of playing key social roles and participate more in collective activities and prevent social deviations and anomalies. In this regard, foresight and the development of a forward-looking strategy model by the media can play an important role in promoting the social health of their audience (individuals).method: This research has been done qualitatively and quantitatively. In the qualitative phase, content analysis and Q methods were used, and in the quantitative phase, factor analysis was used to analyze the Q method data.Results: The content analysis of the media in this study showed that the most media production in the field of social deviations with 576 cases and the lowest media production in the field of violence with 237 cases. The field of social quality with 485 and the field of social issues with 312 cases are in the second and third ranks. A small questionnaire was made and based on it, the desired model was designed using PLS software. Conclusion: This model showed that the function of media is effective in promoting social health of society and can have the greatest impact on improving quality of life, reducing violence, reducing social deviations and social issues.

In this article, an attempt has been made to estimate the amount of sound transmission loss in a flat oval channel by applying the approach of statistical energy analysis. Correct estimation of sound transmission loss in an air conditioning channel is of great importance due to the harmful effects of noise pollution in the environment on human health. Simulation with the statistical energy analysis method is a powerful approach to estimate sound and vibration in problems in which we deal with complex and multi-part systems; is considered. In this method, first, a system is divided into several subsystems, and then by writing a matrix equation that includes the energy exchanges between subsystems and energy loss coefficients; It is investigated from the perspective of vibration and sound estimation.On average, the model presented in this research is able to estimate the sound transmission loss in different dimensions of the air conditioning channels according to the experimental results in the accuracy range of ± 2.5 dB. Considering that it seems that the results obtained from modeling with this method are in good agreement with the experimental data; The results of this research can be used as an efficient approach to estimate noise in oval shaped channels stretched in different lengths.

The doctrine that the content of the conclusion of a deductively valid argument is included in the content of its premises, taken jointly, is a familiar one. It has important consequences for the question of what value valid arguments possess, since it indicates the poverty of three traditional answers: that arguments may and should be used as instruments of persuasion, that they may and should be used as instruments of justification; and that they may and should be used to advance knowledge. The truth is, however, that in each of these cases the argument has only a managerial role and, if there is any work done, it is the premises that do it. It will be maintained that this point has little force against the critical rationalist answer, which I shall defend, that the principal purpose of deductive reasoning from an assemblage of premises is the exploration of their content, facilitating their criticism and rejection. That said, the main aim of the present paper is not to promote critical rationalism but to consider some published objections to the doctrine that a statement asserts every statement that is validly deducible from it. The alleged counterexamples to be considered fall roughly into two groups: statements that emerge with time from a rich mathematical or empirical theory, but were originally unformulated and are deducible from the theory only in a non-trivial way (Frederick 2011, 2014; Williamson 2012); and statements, notably disjunctions, that are easily formulated and are deducible from a theory in a trivial way (Schurz & Weingartner 1987; Mura 1990, 2008; Gemes 1994; Yablo 2014). Each of these counterexamples will be evaluated and dismissed.

Determining the boundaries of genera in subtribe Trigonellinae Small has been one of the most controversial taxonomic issues in this field in last 100 years. Proposing the many characters for separating these genera by various botanists can be considered as a reason for this claim. Characters of the flower parts as well as other vegetative traits have been used extensively. Here on the basis of 5 qualitative and 19 quantitative flower characters we separated Trigonella species (especially perennial section Ellipticae (Boiss. ) Sirj. ) from other genera of this subtribe and showed the results in dendrogram and scatter plot. Placement of the Medicagoid species of section Bucerates (Boiss. ) Sirj. and Medicago L. in one branch and presence of Melilotus indicus (L. ) All. along with other Trigonella species (except section Ellipticae as a distinct branch) are the main results of this investigation.

The purpose of the current research was to investigate the obstacles to the implementation of school-based management in Iran's educational system based on the interpretive structural modeling approach. The research method was a modeling study. The statistical population of the research was specifically the academic staff members of the university, 25 of whom were purposefully selected from the desired cases. The data collection tool was a researcher-made self-interactive questionnaire. In order to measure and evaluate the validity of the questionnaire, the criterion of content validity was used. The content validity of the questionnaire was 0.96. The data analysis was done with interpretive structural modeling method. The results of the research showed that 9 factors play a role as barriers to school-oriented management. Also, the results showed that financial obstacles (the cost of school-oriented management), socio-cultural obstacles and political obstacles (political focus on schools by the central government) as key independent variables have high influence power and low dependence. Also, the results showed that the lack of belief in the professional competence of school administrators, the lack of infrastructure facilities, the emphasis of upper management on the supervision and control of schools, and the lack of cooperation of local communities with school-based management as the linking variables with the greatest power of influence and the greatest power of dependence. and the centralism in the education system of the country and the lack of legal powers to school managers and staff as dependent variables have high dependency power and low influence power.

‫ Pycnocyla spinosa (Umbellifereae) is a wild growing plant in Isfahan, Fars, and Yazd provinces, Iran. The roots of the plant contain substantial amount of sucrose. Seasonal variation of sucrose in the plant was evaluated in order to find out the best collection time for the plant. The root of the plant was collected weekly. The sucrose content of the roots was determined using polarimetr. The results indicate that the best time of collection of P. spinosa is in July. It seems P. spinosa can be considered as a source of sucrose for further agrochemical studies.

In process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight. The volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. Drought stress and dehydrated root reduce. The volume of the pulp extract of 23 ml. The objective of this experiment was to determine the proper method for juice extraction from beet roots grown under drought, salinity and normal conditions in the procedure of sugar content measurement. Sugar beet roots produced under various conditions were subjected to dehydration after harvest. Three levels of dehydration [(A) including fresh beet with 76±1 percent moisture (a1), dehydrated roots up to 70± 1 (a2) and 63± 1 (a3) percent water content] and three juice extraction methods [(traditional cold digestion (b1), hot digestion (b2) and improved French method (b3)] were arranged in a factorial experiment (3*3) in CRD with 12 replications. Sugar content, dry matter, marc, brix and juice electrical conductivity were determined for all treatments. The results showed that beet dehydration from 76 to 68 percent increased both dry matter and marc contents from 24 to 32 and from 4.7 to 7.1 percent, respectively. In normal roots there was no significant difference in terms of sugar content determination by various extraction methods. However, sugar content of beet roots grown under semi-salinity (P<0.05), salinity and drought (P<0.01) conditions were affected significantly by extraction methods. These differences are presumably due to differences in marc and dry matter contents. In conclusion, overall there was no difference between the hot digestion and French methods in all conditions. Whereas, the difference of traditional methods with French method for dry matter of 24 to 27 percent was not significant. Thus, it is recommended to determine sugar content of beet roots having up to 27 percent dry matter by cold digestion method and in the beet roots of greater than 27 percent dry matter the proper way of juice extraction is French method.

Objective Audit quality is a complex concept whose assessment depends on many latent factors. By providing information about them to stakeholders, the public accountability of audit firms contributes to assessing the quality of auditing and determining the extent to which they rely on audit reports. In this regard, this study examined the research in audit firm’, s accountability to extract factors associating firm's accountability, the importance of which was determined by audit partners as experts. methods This research applied a mixed (a combination of qualitative and quantitative data) method with exploratory objective. In this study, 99 papers were analyzed, and 23 experts who selected through the snowball method, ranked the extracted factors. According to the participants’,opinion, the factors were prioritized using the quantitative Entropy-Shannon method. Results Factors connecting to audit firm's accountability divided into three categories including motivating factors (nine categories), disincentive factors (three categories) and accountability dimensions (eight categories). Conclusion The results show that the legal requirements for accountability, active professional associations, stakeholders demand for accountability, active audit committee, social importance of auditor's activities, partners ‘, personal tendency for disclosure, information content of auditor's report, signal to stakeholders and professional ethics play role in audit firms’,accountability context. On the contrary, raising stakeholders’,expectations and disclosure costs are obstacles for audit firms to be accountable. Furthermore, information of the quality control system, the auditing technology, the ownership, the legal and governmental structure, the independence policies, the financial position and performance, professional training and international cooperation are important for the stakeholders of audit firm's accountability.

In this article, the concept of roadmap has been redefined. Many definitions have been put forward by roadmap scientists and these definitions are sometimes similar to each other and in some cases different from one another. While some scientists, like Robert Fall, call it a tool, others like Galvin regard it as an approach. On the other hand, roadmap and strategy, both of which are important strategic issues, are also not very transparent. There is also a difference in the perception of experts in mapping. Differences or deficiencies in the concept of roadmap can lead to inaccurate planning. In this paper, the definitions of scientists as well as the experts’ perceptions are mapped by thematic analysis. The community of experts has been selected for the survey from managers and roadmap experts. According to the results of the analysis, roadmap is an integrated planning tool for strategy realization. In this definition, the concept of roadmap, its relationship to the strategy, and consequently its position in the strategic planning process have been clarified.
