The increasing number of online courses in higher education has provided students with convenience and flexibility. However, some adverse effects also come with online learning, including negatively affecting student beliefs in themselves and their perceptions of the instructor. Both are important factors for academic success. Grounded in media richness theory, this study aims to examine the impact of medium choices by investigating instructor messages on student beliefs and perceptions in an online course.

This study employs a survey methodology using validated items to assess university student perceptions following faculty interactions (video versus customized email).

The authors find that videos and personalized emails, using mass distribution Excel features, help increase student beliefs, including social belongingness and self-efficacy, and improve students' perceptions of the instructor and learning environment.

This study contributes to the literature by establishing that the richness of media of faculty messages can impact student beliefs, which in turn, may help with student success and retention. The activities used in this study are low-effort for the instructor and may have lasting effects on the students. In addition, this study fills a gap in the literature by examining multiple forms of the richness of media and their impact on multiple aspects of students' beliefs and perceptions of the instructor.

This paper addresses a significant research gap in the study of Rayleigh surface wave propagation within a piezoelectric medium characterized by piezoelectric properties, thermal effects and voids. Previous research has often overlooked the crucial aspects related to voids. This study aims to provide analytical solutions for Rayleigh waves propagating through a medium consisting of a nonlocal piezo-thermo-elastic material with voids under the Moore–Gibson–Thompson thermo-elasticity theory with memory dependencies.

The analytical solutions are derived using a wave-mode method, and roots are computed from the characteristic equation using the Durand–Kerner method. These roots are then filtered based on the decay condition of surface waves. The analysis pertains to a medium subjected to stress-free and isothermal boundary conditions.

Computational simulations are performed to determine the attenuation coefficient and phase velocity of Rayleigh waves. This investigation goes beyond mere calculations and examines particle motion to gain deeper insights into Rayleigh wave propagation. Furthermore, this investigates how kernel function and nonlocal parameters influence these wave phenomena.

The results of this study reveal several unique cases that significantly contribute to the understanding of Rayleigh wave propagation within this intricate material system, particularly in the presence of voids.

This investigation provides valuable insights into the synergistic dynamics among piezoelectric constituents, void structures and Rayleigh wave propagation, enabling advancements in sensor technology, augmented energy harvesting methodologies and pioneering seismic monitoring approaches.

This study formulates a novel governing equation for a nonlocal piezo-thermo-elastic medium with voids, highlighting the significance of Rayleigh waves and investigating the impact of memory.

I suggest that the search for Adam Smith’s theodicy is likely to be in vain. The paper begins with a brief history of approaches to evil, emphasizing the context in which they arose, and the questions authors were addressing. Approaches most relevant to Adam Smith include those of Augustine and Calvin, and the early modern theodicies of Leibniz, Samuel Clarke and William King, as well as the attacks on them by Bayle and Voltaire. Scottish Enlightenment writers were not terribly interested in theodicy, though Hutcheson and Kames did devote space to their versions of problems of evil. David Hume’s Dialogues on Natural Religion are often taken to be classic statement of the problem of theodicy and argument against religious belief, but his concern was to demolish rationalistic theodicies rather than religious belief or practice. The paper then turns to Smith’s writings, considering similarities and differences to these approaches to evil. Smith emphasizes the wisdom and beneficence of God, and that evils we observe are part of a larger providential plan. He makes no attempt to justify the God in the face of evil, and in this respect Smith shares more with Augustine and Calvin than he does with the early modern theodicists. Smith’s approach to evil is simple and ameliorative. Smith’s approach contrasts with early nineteenth century English political economists, from Malthus onwards, for whom theodicy was important. Whatever view we take of the theodicists project of justifying an all-powerful and good God in the face of evil may, we still struggle to make sense of economic suffering and evil.

Employees facing challenges in their careers – i.e. female, migrant, elderly and lower-educated employees – might expect job searches to have a low likelihood of success and might therefore more often stay in unsatisfactory positions. The goal of this study is to discover inequalities in job mobility for these employees.

We rely on a large sample of Dutch public sector employees (N = 30,709) and study whether employees with challenges in their careers are hampered in translating job dissatisfaction into job searches. Additionally, we assess whether this is due to their perceptions of labor market alternatives.

Findings show that non-Western migrant, elderly and lower-educated employees are less likely to act on job dissatisfaction than their advantaged counterparts, whereas women are more likely than men to do so. Additionally, we find that although they perceive labor market opportunities as limited, this does not affect their propensity to search for different jobs.

This paper is novel in discovering inequalities in job mobility by analyzing whether employees facing challenges in their careers are less likely to act on job dissatisfaction and therefore more likely to remain in unsatisfactory positions.

The present study explored the young women's lived experiences of discrimination and othering based on skin tone in two rural localities of Uttarakhand , State of India. The authors used intersectionality as the theoretical lens for this study.

The authors have adopted an interpretive phenomenological study in the conduct of this research. The authors interviewed twelve female participants in person using a semi-structured interview schedule. The data were analysed using the six-stage data analysis process of interpretive phenomenological analysis.

The study's findings underline the experiences of stigma, negative self-concept, marriage is a complex reality, media's influence and skin whitening is the first and last resort. Dark-skinned women experience stressful life events due to their skin tone and society's prejudice favouring white and fair skin tones. The experiences of bullying, social shame, guilt and low esteem were also vivid.

This study reveals women's exposure to negative experiences of skin-tone-based discrimination prevalent in Indian society. This is one of the first kinds of such study in India that captures the dark-hued women's recurrent phenomenon of discrimination in their daily lives. It further shows that skin-tone bias and discrimination are widely prevalent and practised despite the claims that Indian society is free from skin-tone biasedness and subsequent discrimination.

This study aims to argue that user’s continued use behavior is contingent upon two perceptions (i.e. the app and the provider). This study examines the moderating effects of user’s perceptions of apps and providers on the effects of security and privacy concerns and investigate whether assurance mechanisms decrease such concerns.

This study conducts a scenario-based survey with 694 mobile cloud computing (MCC) app users to understand their perceptions and behaviors.

This study finds that while perceived value of data transfer to the cloud moderates the effects of security and privacy concerns on continued use behavior, trust only moderates the effect of privacy concerns. This study also finds that perceived effectiveness of security and privacy intervention impacts privacy concerns but does not decrease security concerns.

Prior mobile app studies mainly focused on mobile apps and did not investigate the perceptions of app providers along with app features in the same study. Furthermore, International Organization for Standardization 27018 certification and privacy policy notification are the interventions that exhibit data assurance mechanisms. However, it is unknown whether these interventions are able to decrease users’ security and privacy concerns after using MCC apps.
