Studying language, text and discourse in micro, native and local domains is one of the emphasized streams of research in the newest paradigm of strategy research, namely, “strategy as practice”. This critical study seeks to derive the “what” and “why” of the pattern of Iranian sport mangers decisions from the text of Iranian sport management using qualitative research and drawing on social constructivism philosophy. Accordingly, this study uses grounded analysis and induction-based coding approach through Atlas.ti – specific explorative analysis software. The conclusions are emerged from 12 semi-structured field interviews and 19 secondary documents. The samples result from a combination of purposeful, snowball, convenience, and theoretical sampling methods. Finally, it is discovered that the causal conditions of “economic uncertainty, managerial uncertainty, uncertainty of orientations ambiguity and uncertainty of politicized management” along with the intervening conditions of “past success, background, anxiety-relieving, power structure, and media role” shape the phenomenon of “certainty-demanding discourse” in the context of “stakeholders myopia and lack of independence”. These factors altogether construct the “legitimating strategy” and decisional consequences of tendency to “science, coalition, ethic, promotion, and adaptation”.

Geography is one of the most important determinants of stability or instability in countries. geography is the basis of many social and political developments within countries, even the relations between them and their neighbors. One of the clear examples of this is Afghanistan. This country is known as a crisis-prone country in terms of human geography. War and insecurity, political instability, poverty, extensive internal disputes have plagued the people and this geography for years. The purpose of the current research is to explain the foundations of human geography in the crises of this country. This research is of a descriptive type, whose theoretical framework is obtained from the combination of Hoggett's theory and Cohen's theory, and based on it, the bases and contexts of the crisis in Afghanistan have been explained from a human geographical perspective. According to the findings of the research, all the crises in Afghanistan are affected by human geography and caused by human heterogeneity, the interventions of the powers, as a result of which this country has been in a fragile and unstable situation for years and has remained a crisis maker. Border disputes with neighbors, being landlocked, being a barrier, being located in a fragile region, multiple neighbors, disputes over common border rivers and changing their course are some of the most stable issues of Afghanistan's geography. Ethnicism, linguistic and religious prejudices, extreme fundamentalism, illiteracy, drug cultivation and trafficking, migration, poverty and deprivation, and nomads are among the controversial issues in strengthening humanitarian crises...

The use of enzymes for hydrolysis of protein sources is one of the common methods in the food processing. A hydrolysed protein is a complex mixture of peptides and amino acids that are obtained from hydrolysis by various enzymes, acids or alkali. These peptides play important biological role in the body. The orange seed is largely available from the orange juice industries wastes, and its defatted flour contains about 26% protein and can be used as a rich and cost-effective source for production of proteins and peptides of plant sources. In the present study, a protein isolate with high purity was extracted from defatted orange seed flour and then the protein was hydrolysed by using Alcalase enzyme in concentrations of 1, 1.5 and 3% and the hydrolysis time of 2-5 hours at temperature of 45-55 ° C at suitable pH for enzyme activity. Then the optimal conditions for the production of hydrolysed proteins with the highest antioxidant properties (DPPH radical scavenging activity, radical OH scavenging activity, ferric reducing activity and total antioxidant) were determined. Optimum treatment at determined conditions (temperature 54.8 °C, time 3.35 hr and ration of the enzyme to the substrate 1.7 % v/w) with antioxidant properties (DPPH radical scavenging activity (45.85%), radical OH scavenging activity (91.82%), ferric reducing activity (89.35%) and total antioxidant (39.68%) was obtained and antioxidant tests were performed on the optimal treatment for confirmation of the proposed values by software. The results showed that the hydrolysed protein derived from orange seed could be used in the foods formulation as a natural additive and also it can be used as a nutraceutical with high antioxidant ability.

For determination of the fracture parameters of self-compacting lightweight concrete (SCLC) size effect and work of fracture methods were used. For considering the behavior of concrete in different strengths, two mixes with water to cement (W/C) ratios of 0.42 and 0.47 were utilized. At first, the workability of the concrete was investigated and, after ensuring their self-compacting properties, the mechanical properties of the hardened concrete were determined. Then, by using the above-mentioned methods and conducting three-point bending tests on 30 beams, concrete fracture parameters, and crack-tip opening displacement were achieved. The results showed that with increasing W/C ratio from 0.42 to 0.47, the initial and total fracture energies, and fracture toughness decreased by 39.4%, 33.4% and 25.3%, respectively. The effect of the W/C ratio on the fracture parameters of this type of concrete was discussed. Furthermore, several empirical relations have been proposed that by the use of them and only by the determination of the compressive strength, the initial fracture energy, total fracture energy, the ratio of energies to each other, and fracture toughness can be determined. Then, by using the fracture parameters, the mechanical properties of the concrete and the extended finite-element method, the crack propagation was modeled. The results showed that this method has high accuracy in the numerical solution of the fracture problems as well as the efficiency of the obtained parameters for determining the behavior of self-compacting lightweight concrete.

The aim of the present research is study the effects of climate on some activities, in connection with coastal tourism development in southern shores of Caspian Sea. In this regard, the 25-year meteorological data (1986-2010) of eight synoptic stations were used. In order to evaluate coastal resting feasibility the BCI was used and key & Vamplew model was applied to assess of sport tourism in three fields as parachute, football and Athletics (track). Validation & Comparison of thermal comfort for Mentioned activities & Analyzing of Climatic conditions for coastal development activities was conducted with wind chill index. Analyses based on the outputs of CTIS model and the zonation area was performed by IDW method. The results obtained from the BCI index showed that the appeal of Eastern shores for coastal resting compared to be more than the west one. Based on BCI and wind chill index it was found that the month of June, July and August for coastal resting are more suitable. In contrast, the western shores have better feasibility for windy sport. Although the extent of favorable areas for parachute sports on the eastern shores are higher, but the climate potential on the Western Coast is more favorable. However, the western coast compared to the eastern one have more favorable climatic conditions for the creation of coastal complexes. In general, due to Inappropriate temperature, wind speed and increase foggy, in the months of December, January and February there aren’t favorable conditions for mentioned activities in the western parts.

Under normal circumstances, security and freedom as two human rights must be established in every society in order to protect human values ​​and principles; But in the face of terrorism emergencies, governments may be challenged to combine the two human rights of freedom and security. The predominant approach adopted by countries is a security-oriented approach. This paper first examines the laws and judgments of the United Kingdom, France, and the United States, and explains that governments often ignore freedom of expression in these circumstances. In contrast, there is a freedom-oriented approach that in the face of terrorism with the establishment of freedom, security to some extent ignores this approach and this approach due to the desire for a security-oriented approach by governments can not be adopted by governments and only historical aspects of this approach can be adopted. Found by governments. Finally, further investigation in this regard can lead to the conclusion that in balancing security and freedom, moderation can be maintained and, in times of emergency caused by terrorism, restrictive human rights can be restricted as much as possible; In such a way that neither of the two human rights of security and freedom is violated under the pretext of establishing another.

Although the issue of water rights and especially shared waters has been very important for a long time, But during the transition from the traditional structure, the importance of adhering to the requirements in this field has doubled. The problem of investigating on the allocation of shared waters in the European region due to the large population and lack of resources and in the African region due to the fact that a significant part of these resources has remained unused, has gained great importance and its inappropriate allocation has led to discrimination and deprivation of many people which has affected other dimensions of human rights. In order to solve this challenge and achieve the main goal, i.e. the realization of justice for all members of the human society, the legislative and judicial approach governing the two regions of Africa and Europe regarding the principle of cooperation governing the allocation of shared waters have been analyzed and through matching among them, the strengths and weaknesses of each one has been revealed. Therefore, solutions have been presented to provide good governance and the reasonable and fair allocation of these resources in accordance with the existing social realities in each land which can be applied to other areas that are facing this problem and prevented the occurrence of disputes in this area or the disputes that have occurred continuously resolved peacefully

There are some factors that can pose limit before the performance of obligations and cause obligation to be changed or terminated at all. These factors can have legal or voluntary origins, each of which can be explicit or implicit. Among the factors of administrative origin are the conditions of construction or collusion that can change the obligation. The parties to the obligation in this condition agree to the obligation before or during the contract and make the obligation based on it. The masonry condition without an obligatory statement can be based on the implicit will to change the limits and this can be either increasing or decreasing the obligation and is applicable in property and related rights of individuals and can be an obligation committed to the development and/ or reduce and finally, if not committed to it, could cause the termination or invalidity of the obligation by the parties.
