Understanding stressor-strain relationships during the COVID-19 pandemic : The role of social support, adjustment to remote work, and work-life confl…

2021

This study investigates how the transition to remote work during the coronavirus disease 2019 pandemic is experienced by employees. We investigate to what extent perceived work stressors relate to psychological strain through perceptions of social support, work-life conflict, and adjustment to remote work. The findings expound the mechanisms underlying psychological strain in the context of sudden organizational change. Specifically, this study shows that both challenge stressors and hindrance stressors have negative impact on adjustment to remote work, whereas hindrance stressors are more strongly negatively related to social support. The study further demonstrates that there is hardly any…

What's in it for me and you? : Exploring managerial perceptions of employees' work-related social media use

2022

PurposeThis study focuses on managers' perceptions of employees' communicative role in social media, and explores the changes in the contractual nature of employment relations in mediatized workplaces in which the boundaries of professional and private life are becoming more fluid.Design/methodology/approachA qualitative approach was employed to explore this relatively new phenomenon. The data, comprising 24 interviews with managers responsible for corporate communication and human resources in knowledge-intensive organizations, was thematically analysed.FindingsThe analysis shows that employees' work-related social media use creates new types of exchanges and dependencies between an organi…

Meat substitutes: formulations and comparative analysis

2021

The nutritional quality of animal products is often overlooked in our consumers' imaginations. Sustainability for example, must takeinto account sustainability for humans, starting with meeting their nutritional needs as naturally as possible. For starters, the protein intake, inquantity per 100 g of edible food (usually cooked), greatly exceeds those of vegan equivalents, whether they are meat analogues made fromvegetable proteins or vegetarian dishes reputed to be sources of protein (chickpeas, hummus, lentils, tofu etc.). In addition, it is clear that animalproducts are protein sources of high nutritional quality (DIAAS  80) unlike vegetarian equivalents (DIAAS  80). Animal proteins ar…

Making and breaking relationships on social media: the impacts of brand and influencer betrayals

2021

This study considers how the relationships between social media influencers, brands and individuals are intertwined on social media and analyses the spill-over effects of feelings of betrayal. An experimental design with two transgression scenarios (influencer vs. brand) was created, and 250 individuals were recruited to participate in the study. The results show that a perceived betrayal by a brand can negatively affect the perceived coolness of the social media influencer that has endorsed the brand, as well as the parasocial relationships that followers have with the influencer. Accordingly, a perceived betrayal by a social media influencer can negatively affect attitudes, trust and purc…

The Egan problem on the pull-in range of type 2 PLLs

2021

In 1981, famous engineer William F. Egan conjectured that a higher-order type 2 PLL with an infinite hold-in range also has an infinite pull-in range, and supported his conjecture with some third-order PLL implementations. Although it is known that for the second-order type 2 PLLs the hold-in range and the pull-in range are both infinite, the present paper shows that the Egan conjecture may be not valid in general. We provide an implementation of the third-order type 2 PLL, which has an infinite hold-in range and experiences stable oscillations. This implementation and the Egan conjecture naturally pose a problem, which we will call the Egan problem: to determine a class of type 2 PLLs for …

Adolescents’ online communication and well-being : Findings from the 2018 health behavior in school-aged children (HBSC) study

2022

Background: Digital transformation has influenced all areas of adolescents’ lives, including the ways adolescents maintain friendships. Interpersonal communication is one of the most common activities while online. Online communication may provide adolescents with opportunities to expand their social contacts, but these encounters can be risky, especially when the communication is with unknown people on the internet. This study examined the associations between different forms of online communication behavior and well-being. Materials and methods: Data were collected from Finnish adolescents as part of the Health Behavior in School-Aged Children (HBSC) study in 2018. The participants were 3…

Social information use by predators : expanding the information ecology of prey defences

2022

Social information use is well documented across the animal kingdom, but how it influences ecological and evolutionary processes is only just beginning to be investigated. Here we evaluate how social transmission may influence species interactions and potentially change or create novel selection pressures by focusing on predator-prey interactions, one of the best studied examples of species coevolution. There is extensive research into how prey can use social information to avoid predators, but little synthesis of how social transmission among predators can influence the outcome of different stages of predation. Here we review evidence that predators use social information during 1) encount…

The usage of social media among young adults living in Nairobi, Kenya : only entertainment or contributions to societal change?

2015

Social media usage has been found to have increased all over the world, also in the so-called developing countries. Although the percentages are still rather low, it can be argued that the use of social media is becoming increasingly important also in African countries. Kenya has been found to be one of the leading countries regarding social media usage in East Africa. Although research on social media has been conducted, for instance, on the use of social media in protest movements and in the areas of users’ motivation, less emphasis has been placed on their developmental aspects. Thus, to gain a deeper understanding of the usage of social media in the so-called developing countries, this …

Anthropomorphism and social presence in Human–Virtual service assistant interactions: The role of dialog length and attitudes

2022

In this study, we delve into the perceived quality of recommendations provided by AI-based virtual service assistants (VSAs). Specifically, the role of the social presence of VSAs in influencing recommendation perceptions is investigated. We also explore how the social presence of a VSA is formed and how perceived anthropomorphism plays a vital role in shaping social presence and eventually instilling trust in VSAs among consumers. These relationships are examined in the context of online government services. The results indicate that consumer interaction with VSAs - manifesting via perceived anthropomorphism, social presence, dialog length, and attitudes - improves recommendation quality p…
