91 Addressing resource and waste management challenges imposed by COVID-19: An entrepreneurship perspective
پرداختن به چالش های مدیریت منابع و پسماند که توسط COVID-19 تحمیل شده است: چشم انداز کارآفرینی-2020
This perspective calls for building greater understanding of the role that entrepreneurship plays in addressing the challenges to resource and waste management imposed by COVID-19. We contend that researchers and practitioners need to recognize that entrepreneurs are important change agents who can help in the transition to a more sustainable and circular economy. We present challenges as well as opportunities to address this gap with the goal to foster future research.
Keywords: Entrepreneurship | Entrepreneurial ecosystems | Circular economy | Sustainability | Diversity and inclusion | COVID-19

94 What’s really ‘ Happn ing’? A forensic analysis of Android and iOS Happn dating apps
واقعاً "اتفاق افتاد" چیست؟ تجزیه و تحلیل پزشکی قانونی برنامه های دوستیابی Android و iOS Happn-2020
With today’s world revolving around online interaction, dating applications (apps) are a prime example of how people are able to discover and converse with others that may share similar interests or lifestyles, including during the recent COVID-19 lockdowns. To connect the users, geolocation is often utilized. How- ever, with each new app comes the possibility of criminal exploitation. For example, while apps with ge- olocation feature are intended for users to provide personal information that drive their search to meet someone, that same information can be used by hackers or forensic analysts to gain access to personal data, albeit for different purposes. This paper examines the Happn dating app (versions 9.6.2, 9.7, and 9.8 for iOS devices, and versions 3.0.22 and 24.18.0 for Android devices), which geographically works differently compared to most notable dating apps by providing users with profiles of other users that might have passed by them or in the general radius of their location. Encompassing both iOS and An- droid devices along with eight varying user profiles with diverse backgrounds, this study aims to explore the potential for a malicious actor to uncover the personal information of another user by identifying artifacts that may pertain to sensitive user data.

95 The prospects of waste management in the hospitality sector post COVID-19
چشم انداز مدیریت پسماند در بخش مهمان نوازی پس از COVID-19-2020
COVID-19 has imposed significant detrimental effects on the global hospitality sector. These effects have pri- marily been considered from the socio-economic perspective, ignoring the implications of the pandemic for the environmental performance of hospitality services. By drawing upon emerging evidence from various academicand non-academic sources, this conceptual paper critically evaluates the implications of the preventative and protective measures adopted against COVID-19 for the generation of the hospitality sector’s food and plastic waste. The implications are divided into direct and indirect and considered through the prism of temporality oftheir anticipated occurrence (immediate, short-term and medium-term perspective). The paper proposes po- tential strategies to aid in the management of these wastes in the hospitality sector in a post-pandemic world. To address the issue of food waste, the hospitality sector should be integrated into alternative food networks (AFNs) and short food supply chains (SFSCs). Business coopetition between hospitality enterprises and other actors of the food supply chain is necessary for the success of such integration. To address the issue of plastic waste, thehospitality sector should invest in ‘green’ innovation. This investment needs to be encouraged and supported bytargeted policy interventions. The paper argues that these strategies are critical not only in the context of the COVID-19 pandemic, but will also remain valid for the sustained development of the hospitality sector in light of future disastrous events, especially climate change. The paper discusses the institutional and organisational prerequisites for the effective implementation of these strategies and highlights the related research opportunities.

96 AI4COVID-19: AI enabled preliminary diagnosis for COVID-19 from cough samples via an app
AI4COVID-19: هوش مصنوعی تشخیص اولیه COVID-19 را از نمونه های سرفه از طریق یک برنامه فعال می کند-2020
Background: The inability to test at scale has become humanity’s Achille’s heel in the ongoing war against the COVID-19 pandemic. A scalable screening tool would be a game changer. Building on the prior work on coughbased diagnosis of respiratory diseases, we propose, develop and test an Artificial Intelligence (AI)-powered screening solution for COVID-19 infection that is deployable via a smartphone app. The app, named AI4COVID- 19 records and sends three 3-s cough sounds to an AI engine running in the cloud, and returns a result within 2 min. Methods: Cough is a symptom of over thirty non-COVID-19 related medical conditions. This makes the diagnosis of a COVID-19 infection by cough alone an extremely challenging multidisciplinary problem. We address this problem by investigating the distinctness of pathomorphological alterations in the respiratory system induced by COVID-19 infection when compared to other respiratory infections. To overcome the COVID-19 cough training data shortage we exploit transfer learning. To reduce the misdiagnosis risk stemming from the complex dimensionality of the problem, we leverage a multi-pronged mediator centered risk-averse AI architecture. Results: Results show AI4COVID-19 can distinguish among COVID-19 coughs and several types of non-COVID-19 coughs. The accuracy is promising enough to encourage a large-scale collection of labeled cough data to gauge the generalization capability of AI4COVID-19. AI4COVID-19 is not a clinical grade testing tool. Instead, it offers a screening tool deployable anytime, anywhere, by anyone. It can also be a clinical decision assistance tool used to channel clinical-testing and treatment to those who need it the most, thereby saving more lives.

98 Entrepreneurship and management education: Exploring trends and gaps
کارآفرینی و آموزش مدیریت: بررسی روندها و شکاف ها-2020
Entrepreneurship education is one of the most popular management education subjects due to its ability to link practice with theory. Despite its popularity, research on the topic is still in its in- fancy due to the interdisciplinary nature of the field that makes it unique to study. The aim of this editorial article is to highlight how entrepreneurship education needs to change based on the digital transformation made necessary by the recent COVID-19 crisis. The importance of embedding an entrepreneurship perspective within educational practices is stated that highlights the diversity of the field. The different theoretical underpinnings of entrepreneurship education are also highlighted that suggest a need to think in new directions about possible future peda- gogical approaches. This means it is important to stress the research streams that need more attention based on crisis management techniques in order to deal with the current COVID-19 pandemic. The article makes several suggestions that make it evident that there is merit in introducing novel perspectives that change the nature and way entrepreneurship education is understood in society.

99 Covid-19 and entrepreneurship education: Implications for advancing research and practice
Covid-19 و آموزش کارآفرینی: پیامدهای پیشرفت تحقیق و عمل-2020
This article aims at critically examining the linkage between entrepreneurship education and COVID-19 in order to help understand future research and practice paths. Due to the large global impact COVID-19 has had on society, new entrepreneurial education management practices are required to deal with the change. To do this, this article discusses why COVID-19 can be a transformational opportunity for entrepreneurship education research due to the new thought processes raised by the pandemic. The article suggests several assumptions that have changed as a result of COVID-19 and how entrepreneurship education is required in order to help solve the pandemic. By doing this, the article suggests that more entrepreneurship education research embedding a COVID-19 context is required to breakthrough new frontiers and reset the research agenda. By taking an entrepreneurial stakeholder perspective that looks at entrepreneurship education as a holistic process, an enhanced analysis of how response mechanisms including recovery and change are conducted can be made. This enables a way to view the COVID-19 crisis as an opportunity for more attention placed on the importance of entrepreneurship education for society.

100 Strategic ambidexterity and its performance implications for emerging economies multinationals
دوچرخه سواری استراتژیک و پیامدهای عملکرد آن برای شرکت های چند ملیتی اقتصادهای در حال ظهور-2020
Emerging market multinational enterprises (EMNEs) are attracting significant scholarly attention in the inter-national business and general management domain. The extant research has provided important insights into the EMNEs’ internationalization processes and whether the existing theories adequately explain their outward in- vestment motives. This special issue aims to provide a platform suited to extend the current understanding of the rapid rise of EMNEs and examine the vital role played by strategic ambidexterity and its performance implications for the EMNEs. The current research on EMNEs has failed to adequately leverage strategic ambidexterity and link it with the post-entry performance of EMNEs. We argue that the strategic ambidexterity perspective offers valuable opportunities to understand the post-entry performance of EMNEs as they expand into developed and developing markets. The article also highlights important areas for future research by taking into account the current COVID-19 pandemic crisis.
Keywords: EMNEs | Strategic ambidexterity | Exploration | Exploitation | Internationalization | Emerging market multinationals | COVID-19 crisis
