Predicting social media engagement with computer vision: An examination of food marketing on Instagram
پیشبینی تعامل رسانههای اجتماعی با بینایی رایانه: بررسی بازاریابی مواد غذایی در اینستاگرام-2022
In a crowded social media marketplace, restaurants often try to stand out by showcasing elaborate “Insta- grammable” foods. Using an image classification machine learning algorithm (Google Vision AI) on restaurants’ Instagram posts, this study analyzes how the visual characteristics of product offerings (i.e., their food) relate to social media engagement. Results demonstrate that food images that are more confidently evaluated by Google Vision AI (a proxy for food typicality) are positively associated with engagement (likes and comments). A follow- up experiment shows that exposure to typical-appearing foods elevates positive affect, suggesting they are easier to mentally process, which drives engagement. Therefore, contrary to conventional social media practices and food industry trends, the more typical a food appears, the more social media engagement it receives. Using Google Vision AI to identify what product offerings receive engagement presents an accessible method for marketers to understand their industry and inform their social media marketing strategies.

Typicality: A formal concept analysis account
Typicality: یک حساب تجزیه و تحلیل مفهومی رسمی-2021
We examine typicality—a significant phenomenon accompanying human concepts—within the framework of formal concept analysis. Our aim is to formalize the notion of typicality within this framework and thus provide an operational definition. We review relevant aspects and main psychological explanations of typicality, and propose a formalization based on a view of typicality propounded in the seminal work by Eleanor Rosch et al. We also provide experimental evaluation of our approach and discuss ramifications of our findings and topics to be explored in the future.

Leader prototypicality in sport: The implicit leadership theories of women and men entering sport management careers
نمونه اولیه رهبر در ورزش: نظریه های ضمنی رهبری زنان و مردان که وارد مشاغل مدیریت ورزشی می شوند-2020
Implicit leadership theories (ILTs) matter because they are used as the benchmark against which people determine who is a leader and who is not. This assessment informs their behavioral responses. People are thought to have a superordinate-level ILT representing their prototypical mental model of leadership and a series of basic-level ILTs. Each of these represents how people conceptualize leadership in particular domains (e.g., sport, politics, and popular culture). In this study, the authors generate the structures of basic-level sport management ILTs for women and men who are about to enter this industry. These form the baseline from which socialization to work, organizational cultures, and the sport management industry begins. The ILTs of women entering sport management careers have a 35-item, 6-factor structure (Sensitivity, Knowledgeable, Physical Attractiveness, Inspirational, Dedication, and Focused), whereas men entering the industry have a 32-item, 7-factor structure (Sensitivity, Dedication, Physical Attractiveness, Focused, Creativity, Inspirational, Courageous). The resulting sport management ILT proﬁles differ from superordinate ones by emphasizing physical and vitality attributes, incorporating emotional elements, and by eschewing anti prototypical elements. The paper ends with a discussion of the implications for leadership research in sport management.© 2019 Sport Management Association of Australia and New Zealand. Published by ElsevierLtd.
