One of the main approaches in capacity building and strengthening organizational abilities to integrate activities along the supply chains is the integration, creation, and reconfiguration of internal and external capabilities of components based on the theory of dynamic capabilities. The main assumptions of this theory are based on the purposeful strengthening and promotion of organizational capacities to improve the executive capability of human resources. The objective of this study is to provide a model for promoting dynamic capabilities for international markets of Iran's oil and gas industry. The statistical population includes managers and experts in the field of oil and gas working in the affiliated organizations in Iran. Data were collected using a researcher-made questionnaire whose validity was verified by the content method and its reliability was examined and verified by test-retest method with Spearman correlation coefficient of 0.877 and internal consistency was verified using Cronbach's alpha coefficient. Based on the findings, the dynamic capabilities model was formed on 24 primary factors that were classified into 7 main components. In addition, these components were further classified into four main categories based on the competence-emergency matrix. According to the results, "Strategic conducting of capital resources" accounted for 19.78% of explanatory power and was the most important factor in promoting dynamic capabilities. The findings of the present study can be useful for decision-makers to promote competitiveness in terms of dynamic capabilities in Iran's oil and gas industry.

Adequate reduction of marital conflicts in cardiovascular disease patients helps them cope better with their conditions, as well as improve their quality of life. The aim of this empirical study was to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) on marital conflicts in cardiac patients with a history of coronary artery bypass. The method of this research was semi-experimental with pre- and post-test with a control group. Participants were 30 patients, who were selected through convenience sampling. Participants administered the Marital Conflict Questionnaire (Sanai, Alaghband, Falahati, & Hooman, 2009) as pre- and post-test. Finally, 30 individuals who had the highest scores in the marital conflict questionnaire were selected and randomly assigned to two groups of experimental and control (n=<em>15</em>). To analyze the data, the ANCOVA test was used. The findings of this study indicated that there was a statistically significant effect on the experimental group on the following sub-scales: decreased cooperation, dividing financial affairs and marital conflict. It could be concluded that ACT-based training intervention was effective of the above-mentioned subscales and could be used to reduce marital conflicts in patients with patients with a history of coronary artery bypass. This study indicates the importance of education, as well as psychological interventions as an essential part of the recovery process.

Borders which are specified by natural, man-made or contractual terrain specify the sovereignty limit of a state in a territory and with passing a line-like distance and the border line between two countries we will reach another state with a different political structure. The sensitivity of the border concept and the huge effects it has one national security and wars and conflicts and as well as on interactions between the countries has attracted a special attention toward it. Political geography as the main knowledge regarding the studies about the border possesses a more extensive background comparing to the other related sciences. Typology studies and classification of the borders with studying border from physical or cultural point of view and classifying it based on border conflicts have allocated a special place to them. In line with this, Jones has provided his classification of borders according to their relationships with the type of border conflicts. Considering this approach, the international borders of Iran also, as the lines confiding the territories of this country, have formed a significant part of the academic and geographers, and especially political geographers have conducted management studies in Iran and a large part of these studies. In this study, we intend to classify Iran’s border in terms of Jones perspective with the use of analytical method and from political geography viewpoint. <br />  <br />
