1 The impact of supply chain network structure on relationship management strategies: An empirical investigation of sustainability practices in retailers
تأثیر ساختار شبکه زنجیره تامین بر استراتژی های مدیریت رابطه: بررسی تجربی شیوه های پایداری در خرده فروشان-2021
The implementation of sustainability practices in today’s complex supply chain network (SCN) has been a great challenge for focal firms. To establish a sustainable SCN, understanding is needed about how focal firms’ decision-making processes can be affected by the extent to which they are embedded within a wider stakeholder network. Despite the increasing amount of research in sustainable supply chain management (SSCM), the way (why and how) that focal firms and their SCN actors interact in terms of sustainability practices has not been thoroughly explored. This paper investigates the impact of SCN structure on focal firms’ relationship management strategies (RMS) and identifies strategies that may be employed to implement sustainability practices throughout the SCN. A web-based survey was undertaken to collect data from a sample of 66 Australian food manufacturers and suppliers within two large retailers’ SCNs. The paper’s constructs were validated via exploratory factor analysis, and hierarchical multiple regression analysis was conducted to test the hypotheses. Five factors conceptualizing the SCN structure were identified (transparency, power, supplier dependency, buyer dependency, and distance) to determine the impact of the SCN structure on four RMS (non-compliance, transactional, dictatorial, and collaborative). Results show different relationships between each factor and RMS, thereby providing new insights into the implementation of sustainability practices in the SCN. The findings may assist managers to determine a balance in allocating resources to manage sustainability practices within their firms’ SCNs. This paper is amongst the few empirical works that examine the impact of SCN structure on RMS in SSCM.© 2021 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

2 Environmental management and labor productivity: The moderating role of quality management
مدیریت محیط زیست و بهره وری نیروی کار: نقش تعدیل کننده مدیریت کیفیت-2020
Abundant studies have been made around the impact of environmental management on economic performance in business, but there is still no consistent conclusion. This study focuses on labor productivity as a measure of economic performance. We argue that environmental management has a negative impact on the labor productivity of company in the special context of Chinese increasingly stringent environmental regulations, but this impact is moderated by quality management. Environmental management score and the years that companies have passed ISO 9001 are set as proxies for independent and moderating variable respectively. A sample including 229 Chinese listed companies is used to test the hypotheses by multiple regression analysis. Results show that environmental management has a negative impact on labor productivity, and quality management moderates the relationship.
Keywords: Environmental management | Labor productivity | Quality management | Moderating role

3 How do cultural values influence entrepreneurial behavior of nations? A behavioral reasoning approach
ارزشهای فرهنگی چگونه بر رفتار کارآفرینی ملتها تأثیر می گذارد؟ یک رویکرد استدلال رفتاری-2020
Despite an abundance of research, still there is a gap in understanding the underlying cultural mechanisms behind entrepreneurial behavior of nations in the literature. This study contributes to the debate through a new perspective of analysis based on behavioral reasoning theory (BRT). Specifically, this research analyses the role cultural values play in formation of the reasoning behind entrepreneurial behavior. The data and variables are taken from the GLOBE project and the Global Entrepreneurship Monitor (GEM) for a multiple regression analysis spanning from 2007 to 2017 for 50 countries. The results show that, with the exception of Institutional Collectivism, all of GLOBE’s cultural dimensions affect the reasoning justifications behind entrepreneurial intentions in various countries. Thus, the novel contribution of the present research is the application of BRT in explaining entrepreneurial intentions. This contribution is substantial to the international entrepreneurship field through clarification of the role of cultural values in the reasoning processes behind entrepreneurial activities of nations. Some findings are surprising with regard to the conventional understandings. These findings are fully discussed in the concluding sections.
Keywords: International entrepreneurship | Entrepreneurial intention | Culture | Behavioral reasoning theory

4 Linking methods to outcomes: A multi-course mixed-method study of the effects of active and passive pedagogy on entrepreneurial intentions
پیوند روش ها با نتایج: یک مطالعه چند دوره ای با روش ترکیبی در مورد تأثیرات آموزش و پرورش فعال و منفعل بر اهداف کارآفرینی-2020
This sequential mixed method study explores how pedagogy affects students’ entrepreneurial intentions. It outlines how positivist and constructivist educational paradigms are the basis of¼conventional and entrepreneurial pedagogy, and how these paradigms manifest themselves in entrepreneurship course learning objectives and teaching strategies. This overview engenders a novel coding scheme that supports a double-coder qualitative content analysis of seventeen entrepreneurship course syllabi, from twelve universities in eight countries. The coding results are then quantified and incorporated into a hierarchical multiple regression analysis, using data from a pre-post course student survey (N 232). Contrary to expectations, teaching strategies across the international sample remain relatively conventional, particularly assessments, even for courses that have mostly entrepreneurial course learning objectives. Furthermore, the results did not demonstrate any effect of pedagogy type on students’ entrepreneurial intentions. From all control variables, only ‘pre-course entrepreneurial intentions’ and ‘study level’ are related to (anincrease in) entrepreneurial intentions. Therefore, we recommend that universities target more mature students and do not rely on stand-alone entrepreneurship courses to instill aspirations of entrepreneurship among students. Instead, universities should strive to embed a more constructivist educational approach more widely throughout their curricula.

5 PWR pin-homogenized cross-sections analysis using big-data technology
PWR تجزیه و تحلیل مقطع پین همگن با استفاده از فناوری داده های بزرگ-2020
To accurately and reliably predict the behavior of the nuclear reactor core, pin-by-pin fuel management calculation is becoming the next most possible methodology for the Pressurized Water Reactor (PWR). The fewgroup constants parameterization, however, would be the most challenge problem due to the large number of few-group constants and the complicated pin-cell states during the entire operation history of the reactor core. In this study, the big-data analysis technologies were employed to find a possible relationship between the pin-cell homogenized few-group constants and the pin-cell homogenized nuclide densities. Firstly, correlation analysis demonstrated a strong multicollinearity between different nuclide densities, which implies a significant internal structure and interaction among them. Secondly, by using the factor analysis, the large number of nuclide densities were reduced to a small group of nuclide density factors that can reflect the main information of their variation trends. Thirdly, multiple regression analysis between the nuclide density factors and few-group constants verified the possibility of using nuclide density in form of driven factors as the state parameters to predict the few-group constants.

6 Big-Five personality and aspects of the self-concept: Variable and person centered approaches
شخصیت پنج بزرگ و جنبه های خود مفهومی: رویکردهای متغیر و شخص محور-2018
This study used variable- and person-oriented approaches to examine the importance of Big-Five personality in predicting aspects of the self-concept (i.e., self-control, self-esteem, and self-feelings). The Mini-IPIP scales (IPIP BFM-20), Self-Control Scale (SCS), Rosenbergs Self Esteem Scale (SES), and Test of Self-Conscious Affect (TOSCA-3) were administered to 357 Polish students (59% female). The variable-centered approach, based on multiple regression analysis, revealed that the personality traits explained 5 to 45% of the variance in the self variables, with the largest effect found on self-control. Two-step cluster analysis yielded three personality types, which corresponded to the previously described Resilient, Overcontrolled, and Undercontrolled types, and were meaningfully distinguished on self-variables of interest. However, this type approach showed weaker predictions than continuous and even dichotomized Big-Five traits.

9 Non-financial Value Drivers: Case of Latvian Banks
هدایت کنندگان ارزش های غیر مالی: مورد بانک های لتونی-2017
Non-financial performance is considered to be as much important, as financial results. The significance of non-financial measures will grow, considering the new requirements of the European Parliament regarding the corporate reporting. The goal of the current paper was to identify the most important non-financial bank value drivers, and to investigate the relationship between bank value and non-financial value factors. Research period covered 2012-2015. To achieve the research goal, the authors used expert survey method and statistical data processing, in particular, correlation analysis and multiple regression analysis. The most important value drivers from the viewpoint of banking experts are competence and operating efficiency of bank employees, and effective remuneration and motivation system. Correlation analysis yielded a statistically significant correlation between bank value and all analyzed non-financial bank value indices.

10 ریسک، کارایی و عملکرد بانکداری اسلامی: مطالعه تجربی بر روی بانک اسلامی در اندونزی
سال انتشار: 2016 - تعداد صفحات فایل pdf انگلیسی: 10 - تعداد صفحات فایل doc فارسی: 17
بانکداری یک نهاد بسیار منظم است هم از نظر سرمایه و هم از نظر بودجه و نقدینگی. در این مورد، مدیریت بانک باید بتواند ریسک ها و کارایی را کنترل کند تا عملکرد خود را بهبود بخشد. این مطالعه اثر ریسک و کارایی بر عملکرد بانکداری اسلامی را بررسی می کند. ریسک عبارت است از ریسک تامین اعتبار که توسط تامین اعتبار غیرقابل بازگشت (NPF) اندازه گیری می شود، ریسک سرمایه که توسط نسبت بسندگی سرمایه (CAR) و ریسک نقدینگی که توسط نسبت تامین اعتبار به سپرده (FDR) و پیش نیاز حداقل ذخیره اندازه گیری (RR) می شوند. کارایی نیز توسط نسبت هزینه های عملیاتی به درآمد عملیاتی (OEOI) اندازه گیری می شود. در حالی که عملکرد بانکداری اسلامی توسط بازده دارایی (ROA) و حاشیه سود خالص (NPM) اندازه گیری می شود. این مطالعه شامل 8 بانک اسلامی در اندونزی به همراه داده های فصلی است که با استفاده از تحلیل رگرسیون چندگانه پردازش می شود. نتایج نشان دهنده اثر معنی دار FDR، CAR، OEOI و اندازه عملکرد بانکداری اسلامی هستند برخلاف RR و NPF که اثر معنی داری بر عملکرد بانکداری اسلامی نداشتند.
کلیدواژگان: نسبت تامین اعتبار به سپرده | تامین اعتبار غیرقابل بازگشت | بازده دارایی | حاشیه سود خالص | ریسک | کارایی.
