1 Roles of gender, study major, and origins in accounting learning: A case in Thailand
نقش جنسیت، مطالعه اصلی و ریشه های یادگیری حسابداری: مورد در تایلند-2021
Management students are required to pass several quantitative subjects, such as Accounting, Business Finance, and Mathematics, during their study at the undergraduate level. There are limited studies conducted in Thailand that explored students’ learning achievement in accounting courses. This paper explored the learning achievement of undergraduate management students in the introductory accounting course at a public university in Thailand. It examined whether the achievement differs across the students’ gender, study major, and origins. Data from 906 man- agement students were taken as samples. This study relied on the independent samples t-test and one-way ANOVA to analyze the data. The results suggested that the performance of undergrad- uate management students in the accounting course differs significantly across genders, majors, and origins of the students.

2 Innovation for sustainability in the Global South: bibliometric findings from management & business and STEM (science, technology, engineering and mathematics) fields in developing countries
نوآوری برای پایداری در جنوب جهانی: یافته های کتاب سنجی از مدیریت و تجارت و زمینه های STEM (علم، فناوری، مهندسی و ریاضیات) در کشورهای در حال توسعه-2021
Research on innovation and sustainability is prolific but fragmented. This study integrates the research on innovation in management and business and STEM fields for sustainability in a unified framework for the case of developing countries (i.e., the Global South). It presents and discusses the output, impact, and structure of such research based on a sample of 14,000 þ articles and conference proceedings extracted from the bibliographic database Scopus. The findings reveal research output inflections after global announcements such as UN-Earth Summits. The study also reveals the indisputable leadership of China in overall output and research agendasetting. Nonetheless, countries such as India, Mexico, and Nigeria are either more efficient or impactful. GS research published in highly reputable journals is still scarce but increasing modestly. Central topic clusters (e.g., knowledge management) remain peripheral to the global Sustainable Development Goals (SDGs) research landscape. Finally, academic-corporate collaboration is in its infancy and limited to particular economic sectors: energy, pharmaceuticals, and high-tech.

3 Pre-university students square-root from squared things: A commognitive account of apparent conflicts within learners mathematical discourses
دانشجویان پیش دانشگاهی ریشه میدان از اشیا مربع شده: یک گزارش فراوانی از درگیری های ظاهری در گفتمان های ریاضی یادگیرندگان-2021
This study explores the grasp of square roots among eleven students in a remedial mathematics course, with a special focus on where the same student generated apparently conflicting re- sponses. Building on the commognitive framework, the analysis distinguished between routines that individual students consistently implemented in situations where roots “stood alone” and where they were incorporated in more compound exercises, where roots were extracted from square numbers and from squared radicands, where roots were applied to monomials and bi- nomials, and where parameters named with different letters were involved. Differences were found in routines’ degree of objectification, procedures, and tasks. These differences are explained with a theoretical account, suggesting that what may seem as a conflict within a stu- dent’s discourse could be a sensible difference of actions taken in situations that this student construed as different. The contribution of this study to the body of knowledge on teaching and learning of roots and to commognitive research is discussed.

4 Qualitative and quantitative project risk assessment using a hybrid PMBOK model developed under uncertainty conditions
ارزیابی ریسک کمی و کیفی پروژه با استفاده از یک مدل توسعه یافته PMBOK تحت شرایط غیر قطعی-2020
This study presented a qualitative and quantitative project risk assessment using a hybrid PMBOK model developed under uncertainty conditions. Accordingly, an exploratory and applied research design was employed in this study. The research sample included 15 experienced staff working in main and related positions in Neyr Perse Company. After reviewing the literature and the Project Management Body of Knowledge (PMBOK), 32 risk factors were identified and their number reduced to 17 risks using the expert opinions via the fuzzy Delphi technique run through three stages. The results of the confirmatory factor analysis showed that all risks were confirmed by the members of the research sample. Then the identified risks were structured and ranked using fuzzy DEMATEL and fuzzy ANP techniques. The final results of the study showed that the political and economic sanctions had the highest weight followed by foreign investors’ attraction and the lack of regional infrastructure.

6 Project schedule performance under general mode implementation disruptions
عملکرد برنامه پروژه تحت اختلال در اجرای کلی حالت-2020
This paper presents a simulation study for a resource-constrained project scheduling problem with mul- tiple alternatives. We decide on a set of baseline schedules at the project planning phase, resulting in options to switch between execution modes of activities during project execution. We assess the perfor- mance of the set of baseline schedules under general mode implementation disruptions. A simple, yet effective algorithm is presented to construct the set of baseline schedules. Moreover, a general disruption system is proposed to model different disruption types, disruption dependencies and disruption sizes.

8 Application of machine learning to laboratory safety management assessment
کاربرد یادگیری ماشین در ارزیابی مدیریت ایمنی آزمایشگاهی-2019
This paper proposes a new method to evaluate laboratory safety management based on machine learning that aims to address the shortcomings of traditional laboratory safety evaluation methods, including poor accuracy, large influence of human factors, and lack of a unified evaluation system. In this paper, the safety data of laboratories in Southwest University were collected using a safety checklist, and the weight of each factor affecting laboratory safety was analyzed using a Fuzzy Analytic Hierarchy Process (FAHP). The simulation results showed that the model gave a more accurate and reasonable safety risk level of the laboratory, verified the rationality and feasibility of the established method, and realized potential loopholes in the process of laboratory management and college students operations. According to the evaluation results, the machine learning principle and the existing maintenance knowledge of the evaluation knowledge base are applied to provide effective measures and suggestions for users to complete the process of risk assessment. Through risk assessment, the professional skill and the incident control could be improved. The model was easy to operate and has a good application value for ensuring the personal and property safety of laboratory users.

9 The mechanics of commercial banking liberalization and growth
ریاضیات آزادسازی و رشد بانکداری تجاری-2018
This paper formalizes the effects of liberalization across the border of deposit-taking and lending activities on the regime of competition in the banking market and on the rate of growth of the economy. We extend two economy based Deidda (2006)’s banking model in which originally each economy hosts at least one operating bank. We introduce two GATS-defined modes of commercial banking liberalization – namely the Commercial Presence mode and the Cross-Border mode. Additionally, we introduce the possibility of strategic behavior by competing banks in equilibrium. The extended model provides a causal link between the cost structure of the banking industry, the regime of competition in the liberalized banking sector and the rate of growth of the economy under alternative modes of liberalization. In particular, we show a threshold effect in terms of economic development: above certain economic development the banking sector operates competitively and supports an accelerating rate of growth, generating a bidirectional, self-reinforcing link between commercial banking liberalization and growth. The pace of growth is further increased, with respect to a scenario where such behavior is not present, by the presence of strategic behavior by competing banks in equilibrium.

10 SecSVA: Secure Storage, Verification, and Auditing of Big Data in the Cloud Environment
SecSVA: ذخیره سازی امن، تایید و حسابرسی داده های بزرگ در محیط ابر-2018
With the widespread popularity of Internet-enabled devices, there is an exponential increase in the information sharing among different geographically located smart devices. These smart devices may be heterogeneous in nature and may use different communication protocols for information sharing among themselves. Moreover, the data shared may also change with respect to various Vs (volume, velocity, variety, and value) to categorize it as big data. However, as these devices communicate with each other using an open channel, the Internet, there is a higher chance of information leakage during communication. Most of the existing solutions reported in the literature ignore these facts. Keeping focus on these points, in this article, we propose secure storage, verification, and auditing (SecSVA) of big data in cloud environment. SecSVA includes the following modules: an attribute-based secure data deduplication framework for data storage on the cloud, Kerberos-based identity verification and authentication, and Merkle hash-tree-based trusted third-party auditing on cloud. From the analysis, it is clear that SecSVA can provide secure third party auditing with integrity preservation across multiple domains in the cloud environment.
Keywords: Big Data, cloud computing, data integrity, security of data, storage management,trees (mathematics)
