1 The lived reality of public accounting interns
واقعیت زندگی کارآموزان حسابداری عمومی-2021
This study examines the lived reality of public accounting interns, including perceived benefits, costs, and competing frictions that are collectively relevant to the norms and social structures in this labor market. Our evidence suggests that benefits include knowledge acquisition for interns and readily available labor for firms. Costs include ethical dilemmas, pressures to conform, reality shocks, and shared suffering for interns, along with training investments and turnover for firms. Labor market frictions include variation in perceptions of success versus failure for interns, coupled with sustainability implications for the hiring model of firms. Reflecting on the mutuality of these labor market attributes, we present evidence on the consequences for both individuals and the profession. To do so, we collect survey evidence from 257 students who completed a ‘busy-season’ internship in the semester immediately prior to embarking on their Masters of Accountancy (MACC) program (January-April of 2014, 2015 and 2016). After reflecting on insights from that evidence, we then interviewed another 30 MACC students who had returned from their internships following the busy season of 2017 to gain in-depth qualitative evidence about the ‘lived reality’ of the internship experience, focusing on insights about anticipatory socialization, formative experiences and assimilation, along with differential expressions of both success and painful instances of failure. Our study provides details on a replicable internship model that has been sustainable for over 20 years at the University of Wisconsin – Madison, and represents a detailed example relevant to understanding the apprenticeship model of public accounting.

2 Interorganizational imitation in supply chain relationships: The case of inventory leanness
تقلید بین سازمانی در روابط زنجیره تامین: مورد ناب بودن موجودی کالا-2021
We examine the extent to which suppliers assimilate to their customers’ inventory leanness levels. Drawing on institutional theory, we hypothesize that there is a positive relationship between major customer and supplier inventory leanness and that this effect is moderated by compliant, reflexive, and normative isomorphic forces. Specifically, we contend that interdependence, uncertainty, and the age of the customer—supplier relationship strengthen the supplier’s imitative behaviors and, thus, the assimilation to its major customer’s inventory leanness. The hypotheses are tested empirically using a large panel data set of dyadic customer–supplier observations obtained from a variety of archival databases. The econometric analyses provide strong and robust evidence of interorganizational imitation in the domain of inventory management and, thus, document the role key customers play in shaping supplier firms’ inventories. We discuss implications of our research for the further development and broadening of the academic inventory literature as well as managerial practice.

3 Linking big data analytical intelligence to customer relationship management performance
پیوند دادن هوش تحلیلی داده های بزرگ با عملکرد مدیریت ارتباط با مشتری-2020
This study investigates the driving forces of a firm’s assimilation of big data analytical intelligence (BDAI) and how the assimilation of BDAI improve customer relationship management (CRM) performance. Drawing on the resource-based view, this study argues that a firm’s data-driven culture and the competitive pressure it faces in the industry motivate a firm’s assimilation of BDAI. As a firm resource, BDAI enables an organization to develop superior mass-customization capability, which in turn positively influences its CRM performance. In addition, this study proposes that a firm’s marketing capability can moderate the impact of BDAI assimilation on its mass- customization capability. Using survey data collected from 147 business-to-business companies, this study find ssupport for most of the hypotheses. The findings of this study uncover compelling insights about the dynamics involved in the process of using BDAI to improve CRM performance.

4 Automatic and adaptive localization for ensemble-based history matching
محلی سازی خودکار و سازگار برای تطبیق تاریخ مبتنی بر گروه-2020
Ensemble-based history matching methods are among the state-of-the-art approaches to reservoir characterization. In practice, however, they often suffer from ensemble collapse, a phenomenon that deteriorates history matching performance. To prevent ensemble collapse, it is customary to equip an ensemble history matching algorithm with a certain localization scheme. In a previous study, the authors propose an adaptive localization scheme that exploits the correlations between model variables and simulated observations. Correlation-based adaptive localization not only overcomes some longstanding issues (e.g., the challenges in handling non-local or time-lapse observations) arising in the conventional distance-based localization, but also is more convenient and flexible to use in real field case studies. In applications, however, correlation-based localization is also found to be subject to two problems. One is that, it requires to run a relatively large ensemble in order to achieve decent performance in an automatic manner, which becomes computationally expensive in large-scale problems. As a result, certain empirical tuning factors are introduced to reduce the computational costs. The other problem is that, the way used to compute the tapering coefficients in the previous study may induce discontinuities, and neglect the information of certain still-influential observations for model updates. The main objective of this work is to improve the efficiency and accuracy of correlation-based adaptive localization, making it run in an automatic manner but without incurring substantial extra computational costs. To this end, we introduce two enhancements that aim to avoid the aforementioned two problems, namely, empirical tuning and discontinuities. We apply the resulting automatic and adaptive correlation-based localization with these two enhancements to a 2D and a 3D cases investigated in the previous study, and show that it leads to better history matching performance (in terms of efficiency and/or estimation accuracy) than that is achieved in the previous work.

5 The impact of social media on consumer acculturation: Current challenges, opportunities, and an agenda for research and practice
تأثیر رسانه های اجتماعی بر جمع آوری مصرف کننده: چالش های فعلی ، فرصت ها و دستور کار برای تحقیق و عمل-2020
The concept of acculturation has been based on the assumption of an adaptation process, whereby immigrants lose aspects of their heritage cultures in favour of aspects of a host culture (i.e. assimilation). Past research has shown that acculturation preferences result in various possibilities and influence consumption behaviour. However, the impact of social media on consumer acculturation is underexplored, although the social purpose and information sharing online is utilized for a variety of social purposes. Recent studies have shown the transformation from an offline to an online context, in which social networks play an integral part in immigrants’ communications, relationships and connections. This study merges the views from a number of leading contributors to highlight significant opportunities and challenges for future consumer acculturation research influenced by social media. The research provides insights into the impact of social media on consumer acculturation.

6 Subsurface velocity inversion from deep learning-based data assimilation
وارونگی سرعت زیرسطحی از جذب داده های مبتنی بر یادگیری عمیق-2019
Data assimilation haswidespread applications inmeteorology and oceanography. This paper applies data assimilation for seismic exploration. Comparing with full waveform inversion, the distrust of the prior velocity information is preserved, to avoid the local minima caused by its inaccuracy. Prior velocity information is scarce in seismic exploration, but the introduction of deep learningmethods makes it possible, to correct the major defects in the application of data assimilation in seismic velocity inversion. Finally, we design a simple salt body model, and we introduce deep learning to obtain prior velocity information and drive data assimilation for highprecision inversion of subsurface velocity. It is compared with the traditional full waveform inversion, to prove the effectiveness and advantages of this new process.

7 “There is still peace: There are no wars:”: Prioritizing unity over diversity in Botswana’s social studies policies and practices and the implications for positive peace
"هنوزهم صلح وجود دارد: هیچ جنگی وجود دارد": اولویت سازی اتحاد بر اختلاف در سیاست ها و روشهای مطالعات اجتماعی بوستوانا و دلالت ها برای صلح مثبت-2018
This article examines the ways in which education policy and practice in Botswana negotiate tensions between assimilationist and multiculturalist approaches to ethnic diversity. We find that the curriculum, as written and as taught, is preoccupied with unity and the avoidance of armed conflict, goals that have perpetuated an assimilationist approach, normed around the culture and language of the Tswana ethnic majority. We argue that a multicultural approach could foster conditions of positive peace, including recognition and equality of opportunity across ethnic groups, which is more urgent today given the sustained absence of armed conflict. We offer strategies for how practitioners and policy makers might move forward in transforming existing multicultural policy discourse into multicultural school practices.

8 Knowledge absorptive capacity and innovation performance in high-tech companies: A multi-mediating analysis
ظرفیت جذب دانش و عملکرد نوآوری در شرکت های با تکنولوژی بالا: تجزیه و تحلیل چند واسطه-2018
Building upon the knowledge-based view (KBV) and using data from 379 high-tech companies in China, we examine the underlying, mediating mechanisms in the relationship between knowledge absorptive capacity and firms innovation performance. We find that there are positive relationships between four dimensions of knowledge absorptive capacity (i.e., knowledge acquisition, knowledge assimilation, knowledge transformation, and knowledge exploitation) and firms innovation performance. Additionally, we discover that both firms knowledge transformation capacity and knowledge exploitation capacity mediate the relationship between knowledge acquisition and firms innovation performance, as well as between knowledge assimilation and firms innovation performance. Our results shed light on knowledge absorptive capacity research and knowledge management theory by theoretically and empirically demonstrating how knowledge absorptive capacity affects firms innovation outputs from a multi-mediating perspective.

10 پیش بینی موازی اطلاعات سراسر جامعه با به دست آوردن داده ها از شبکه های اجتماعی
سال انتشار: 2018 - تعداد صفحات فایل pdf انگلیسی: 8 - تعداد صفحات فایل doc فارسی: 18
امروزه شبکه¬های اجتماعی به یکی از منابع اصلی اطلاعات تبدیل شده است. عوامل بسیاری بر این گسترش اطلاعات تأثیر دارد. از یک سو، ما باید به گزارش ویژگی¬های پست و منابع اطلاعات بپردازیم، از سوی دیگر، لازم است تا درک کنیم که چگونه کاربران روی پست ها واکنش نشان می دهند. علاوه بر این، شبکه های اجتماعی (و همچنین برخی از سیستم های طبیعی و فنی) به ما برای جمع آوری این داده ها در باره حالت واقعی روند دینامیک امکان می دهد، بدین ترتیب این ورودی داده ها امکان ادغام در داخل این شبیه سازی را فراهم می¬آورد. در این مقاله، ما یک رویکرد چند عاملی برای پیش بینی انتشار اطلاعات را با توجه به داده های گذشته و اطلاعات مربوط به وضعیت عامل ها در یک شبکه اجتماعی پیشنهاد می¬کنم. در طی روند شبیه سازی، این مدل حالت شبکه داده ها را در فرم دسته ای دریافت می کند و می توان مولفه های داخلی برای پیش بینی دقیق¬تر را تغییر دهد. تحقق موازی این روش به ما امکان می دهد تا شبیه سازی را در یک زمان معقول انجام دهیم. نتایج نشان می¬دهد که با استفاده از اطلاعات اضافی جمع آوری شده از شبکه اجتماعی آنلاین، دقت پیش بینی می تواند به طور قابل توجهی بهبود یابد.
