1 iRestroom : A smart restroom cyberinfrastructure for elderly people
iRestroom: زیرساخت سایبری سرویس بهداشتی هوشمند برای افراد مسن-2022
According to a report by UN and WHO, by 2030 the number of senior people (age over 65) is projected to grow up to 1.4 billion, and which is nearly 16.5% of the global population. Seniors who live alone must have their health state closely monitored to avoid unexpected events (such as a fall). This study explains the underlying principles, methodology, and research that went into developing the concept, as well as the need for and scopes of a restroom cyberinfrastructure system, that we call as iRestroom to assess the frailty of elderly people for them to live a comfortable, independent, and secure life at home. The proposed restroom idea is based on the required situations, which are determined by user study, socio-cultural and technological trends, and user requirements. The iRestroom is designed as a multi-sensory place with interconnected devices where carriers of older persons can access interactive material and services throughout their everyday activities. The prototype is then tested at Texas A&M University-Kingsville. A Nave Bayes classifier is utilized to anticipate the locations of the sensors, which serves to provide a constantly updated reference for the data originating from numerous sensors and devices installed in different locations throughout the restroom. A small sample of pilot data was obtained, as well as pertinent web data. The Institutional Review Board (IRB) has approved all the methods.

2 A holistic approach to health and safety monitoring: Framework and technology perspective
رویکردی جامع برای نظارت بر سلامت و ایمنی: چارچوب و دیدگاه فناوری-2022
Existing H&S monitoring methods are manual, cumbersome, time consuming and issues with safety compliance and use of PPE remain a concern. With the existing manual H&S processes, there are significant delays and, in some cases, even failure to report incidences, resulting in no or slow improvements to safety. This paper proposes a prototype PPE access monitoring system which combines smart PPE and an indoor/outdoor personnel location monitoring system. The paper also proposes a generic framework to be used for smart gateway services within a manufacturing site to augment and enable smart PPE, separating areas of high and low risk. The prototype automated PPE detection gate presents a practical use of the framework and demon- strates a suitable method for assessing workforce/visitor PPE compliance. Its secondary function is to act as a location waypoint system to support other location tracking methods, identified in the literature and throughout the testing protocol. The system could be further adapted to support augmented personnel within the Operator 4.0 paradigm to improve site safety, monitoring and control.

3 Intellectual engagements of accounting academics: The ‘forecasted losses intervention
تعاملات ذهنی دانشگاهی حسابداری: مداخله زیان پیش بینی شده-2021
This paper explores the social and political potential of accounting scholarship, presenting and discussing an intellectual intervention challenging a legislative reform that significantly affected Spanish industrial relations. In this reform, an accounting artifact (forecasted losses) played an unexpected role and was misrepresented, prompting a sizeable number of scholars to sign two manifestos in 2010 and 2012 against the use of forecasted losses made by the new legislation. As promoters of this manifesto, we perform in this paper a collaborative autoethnography to reflect on the context, events, reactions, and significance of this intervention for both the academic and the industrial relations fields. We mobilize Pierre Bourdieu’s ideas on the public intellectual to think more generally about academic engagements in the interplay between accounting, poli- cymaking, and social issues. This intervention illustrates the different manners in which admin- istrative and economic powers interfered in the Spanish accounting academic field, limiting the disposition of Spanish scholars to engage in public debates. We also interpret our engagement as mobilizing intellectual capital to expose how the notion of forecasted losses was used to produce a form of symbolic violence and how this capital is more effective as it produces messages addressed to the producers, i.e., policymakers and the judicature in this specific case.

4 Disaster management training in the euregio-meuse-rhine: What can we learn from each other to improve cross-border practices?
آموزش مدیریت بلایا در euregio-meuse-rhine: برای بهبود شیوه های فرامرزی چه چیزی می توانیم از یکدیگر بیاموزیم؟-2021
Increasing numbers of disasters require comprehensive preparedness. Border regions are vulnerable as disasters might not halt at administrative borders. Cross-border coordination is therefore required. As integral part of cross-border collaborations initiative in the Meuse–Rhine Euregio (EMR), we reviewed published evidence informing on existing initiatives dedicated to disaster education in the EMR. A search based on the PRISMA guidelines for scoping reviews was conducted to retrieve articles in the following databases: Medline, PsychInfo and Scopus. The searches were limited to English, French, Dutch and German language articles and the period between January 2010 and June 2019. No restrictions were set for the study design or the type of methodology used. A total of 18 articles met the inclusion criteria out of a total of 1771 publications. Training development was found in two studies while nine studies focused on the state of knowledge in disaster management. Seven articles referred only to technical skills, three only to non-technical skills and eight combined both types of skills. For the technical nature, Knowledge was found seven times, Skills five times and Attitudes twice. On the non- technical side, Knowledge was found three and both Skills twice and Attitudes three times. Five studies trained and assessed all the Knowledge, skills and attitudes. Most of the studies constitute inventories with descriptive reporting and very few experimental studies of quality have been carried. Non-technical skills for disaster preparedness have been well considered among the articles. Cross-border collaboration needs to be further investigated.

5 Dynamic resilience for biological wastewater treatment processes: Interpreting data for process management and the potential for knowledge discovery
انعطاف پذیری پویا برای فرآیندهای تصفیه بیولوژیکی فاضلاب: تفسیر داده ها برای مدیریت فرآیند و پتانسیل برای کشف دانش-2021
Climate change, population growth and increasing regulation are causing wastewater treatment plants to become increasingly stressed, especially in countries like the UK, where many of these systems date back to the early part of the 20th century. Understanding resilience dynamics for these ageing wastewater assets represents a funda- mental step in classifying multi-dimensional water stressors toward preventing severe pollution incidents. This paper explores the potential of a novel dynamic resilience approach to assess and predict the dynamic resilience of biological wastewater treatment based on the separation of stressor events (cause) and process stress (effect) to consider the deviation from reference conditions. The approach presented provides a fundamental link between (1) conventional activated sludge modelling methodologies, (2) actual biological wastewater process instrument data (potential for knowledge discovery) and (3) the characterisation of dynamic resilience in wastewater treatment processes. Results first present the dynamic resilience approach by modelling simulated shock flow conditions on an activated sludge plant, then incorporates ten years of wastewater process instrument data to demonstrate the actual dynamic resilience. The aim is to represent the “dynamic resilience” as self-ordering windows, a visual knowledge base (three dimensional, heat map), which operational staff can easily interpret. The outcomes presented suggest that such an approach is feasible and has the potential for real-time identifi- cation of conditions that result in pollution incidents based on actual historical process instrument data (knowledge discovery). Also, the methods presented could be extended to develop an improved understanding of wastewater system resilience under a range of future stressor scenarios.

6 ارتقای تحلیل قابلیت اطمینان انسان برای سیستم‌های ریلی با استفاده از منطق فازی
سال انتشار: 2021 - تعداد صفحات فایل pdf انگلیسی: 15 - تعداد صفحات فایل doc فارسی: 40
اتحادیه‌ی بین‌المللی راه‌آهن در گزارش ایمنی سالانه‌ی خود بر این نکته تأکید دارد که هر ساله عامل انسانی یکی از علل اصلی حوادث ریلی به شمار می‌آید. در نتیجه، مطالعه‌ی قابلیت اطمینان انسان یک اصل اساسی بوده و بایستی در ارزیابی کامل قابلیت اطمینان برای تمامی سیستم‎‌های ریلی گنجانده شود. بااینحال، RARA (ارزیابی قابلیت اطمینان عملکرد ریلی) تنها رویکرد موجود در متون و مقالات است که عملکرد انسان را لحاظ نموده و مختص به کاربردهای ریلی است. اشکال اصلی RARA تأثیر ذهنیت متخصص و دشواری ارزیابی عددی برای پارامترهای مدل در نبود یک پایگاه داده‌ی جامع برای خطا و حوادث ترافیکی است. این مقاله یک مدل فازی نوآورانه برای ارزیابی عامل انسانی در سیستم‌های حساس به ایمنی برای کاربردهای ریلی جهت حل و فصل مشکلات بیان‌شده ارائه می‌دهد. منطق فازی امکان ساده‌سازی ارزیابی پارامترهای مدل با استفاده از متغیرهای کلامی بسیار شبیه به فرایند شناختی انسان را فراهم می‌آورد. به علاوه، این با شیوه‌ای به مراتب بهتر از روش قطعی کلاسیک با داده‌های ناقص و فاقد عدم قطعیت برخورد نموده و انتزاعی بودن ارزیابی تحلیلگر را به حداقل می‎رساند. خروجی الگوریتم پیشنهادی، نتیجه‌ی محاسبات بازه‌ای فازی، نظریه‌ی α-cut و روش فازی‌زدایی مرکز ثقل است. روش پیشنهادی برای عملکردهای انسانی انجام‌گرفته در یک سیستم پیام‌رسانی ریلی استفاده شده است. چهار اقدام انسانی و دو سناریو جهت تحلیل عملکرد الگوریتم پیشنهادی شبیه‌سازی شدند. نهایتاً نتایج این روش با روش RARA کلاسیک مقایسه شده و بیانگر نتایج سازگار با رویکردی ساده‌تر و شهودی‌تر با پیچیدگی کمتر است.

7 Knowledge spillover, knowledge management capabilities, and innovation among returnee entrepreneurial firms in emerging markets: Does entrepreneurial ecosystem matter?
سرریز دانش، قابلیت‌های مدیریت دانش و نوآوری در میان شرکت‌های کارآفرین بازگشته در بازارهای نوظهور: آیا اکوسیستم کارآفرینی اهمیت دارد؟-2021
The paper brings an entrepreneurial ecosystem approach to examine the conditions under which returnee en- trepreneurs can overcome their liabilities and promote innovation in emerging markets. The existing literature has focused on how returnee entrepreneurial firms can transit knowledge to local firms with the assumption that the former are more innovative than the latter. However, returnee entrepreneurial firms themselves experience difficulties in achieving superior innovation performance as they face liabilities when returning to their home countries. In this paper, we argue that such firms can take advantage of the knowledge spillover in the entre- preneurial ecosystem to promote innovation performance by enhancing their own knowledge management capability. The empirical evidence supports this proposition. Although we proposed that this relationship is likely contingent upon the attributes of entrepreneurial ecosystem, empirical evidence does not support it. Theoretical and practical implications are discussed.

8 Accounting for uncertainties due to high-impact low-probability events in power system development
محاسبه عدم قطعیت های ناشی از رویدادهای با احتمال کم تاثیر زیاد در توسعه سیستم قدرت-2021
In the long-term development of the electric power system, system operators should consider the socio-economic balance between grid investment costs and security of supply, including the risk of power supply interruptions. Cost-benefit analyses conducted for this purpose are associated with many uncertainties but have traditionally focused on the expected value of the net socio-economic benefits of risk-reducing measures. This article focuses on the large uncertainties that are associated with the possible occurrence of high-impact low-probability interruption events (HILP events). The objective is to quantify and visualize the implications of uncertainties due to HILP events in the context of power system development. More specifically, this article describes a method- ology accounting for uncertainties in socio-economic cost-benefit analysis of measures for reducing the risk of HILP events. The methodology accounts for the contributions of both aleatory and epistemic uncertainties and comprises a hybrid probabilistic-possibilistic uncertainty analysis method. Applying the methodology to a real case involving a grid investment decision, it is demonstrated how it provides additional insight compared to conventional cost-benefit analyses considering expected values where uncertainties are not accounted for explicitly. It is furthermore discussed how these results can help to better inform grid development decisions.

9 A knowledge-based Digital Shadow for machining industry in a Digital Twin perspective
یک سایه دیجیتال مبتنی بر دانش برای صنعت ماشینکاری در یک چشم انداز دیجیتال دوتایی-2021
This paper addresses the problems of data management and analytics for decision-aid by proposing a new vision of Digital Shadow (DS) which would be considered as the core component of a future Digital Twin. Knowledge generated by experts and artificial intelligence, is transformed into formal business rules and integrated into the DS to enable the characterization of the real behavior of the physical system throughout its operation stage. This behavior model is continuously enriched by direct or derived learning, in order to improve the digital twin. The proposed DS relies on data analytics (based on unsupervised learning) and on a knowledge inference engine. It enables the incidents to be detected and it is also able to decipher its operational context. An example of this application in the aeronautic machining industry is provided to stress both the feasibility of the proposition and its potential impact on shop floor performance.

10 DATA BREACH MANAGEMENT: AN INTEGRATED RISK MODEL
مدیریت نقض داده ها: یک مدل ریسک یکپارچه-2021
In response to organizations’ increasing vulnerability to data breaches, we present an integrated risk model for data breach management based on a systematic review of the literature. Theoretically, the study extends the body of knowledge on data breach management by identifying and updating conceptualizations of data breach risks (items) and resolutions (actions) and by providing a foundation for organizational responses to emerging data breach incidents (heuristics). Practically, the study provides key insights that practitioners can use to organize and orchestrate effective data breach management based on comprehensive profiles of risk items and resolution techniques.
