Presents a robust and unconditionally stable return‐mapping algorithm based on the discrete counterpart of the principle of maximum plastic dissipation. Develops the explicit expression for the consistent elasto‐plastic tangent modulus. All expressions are derived via tensor formulation showing the advantage over the classical matrix notation. The integration algorithm is implemented in the formulation of the four‐node isoparametric assumed‐strain finite‐rotation shell element employing the Mindlin‐Reissner‐type shell model. By applying the layered model, plastic zones can be displayed through the shell thickness. Material non‐linearity described by the von Mises yield criterion and isotropic hardening is combined with a geometrically non‐linear response assuming finite rotations. Numerical examples illustrate the efficiency of the present formulation in conjunction with the standard Newton iteration approach, in which no line search procedures are required. Demonstrates the excellent performance of the algorithm for large time respective load steps.

Zu den individuellen Einflüssen zählen persönliche Liebhabereien oder die Notwendigkeit einer Erholungskur infolge Erkrankung oder während der Rekonvaleszenz nach einer Krankheit oder einer Operation; zu den kollektiven Faktoren gehören dagegen Schul‐ oder Betriebsferien, günstige Reisegelegenheiten oder besonders geeignete Jahreszeit.

The introduction of digital resources has not only had considerable impact on the role of libraries in the information society, but it has also had a remarkable effect on back office procedures, i.e. on the way the library is organised. This article presents a case study of a reengineering process at the Bayerische Staatsbibliothek (Bavarian State Library) in Munich, Germany, the central regional library of the State of Bavaria and one of the largest academic research libraries in Europe with local, regional and supraregional responsibilities. Due to the multiple roles of this library, it was particularly important not only to bridge the gap between traditional and new material, but also to create a flexible organisational platform for the various tasks at the different levels indicated.

The Covid-19 pandemic has profoundly affected urban communities, generating the need for an immediate response from local governance. The availability of urban data platforms in some smart cities helped the relevant actors to develop various solutions in an innovative and highly contextual way. The purpose of this paper is to explore the role of data platforms in smart cities in the context of the Covid-19 crisis.

A total of 85 studies were identified using the Clarivate Analytics Web of Science electronic library. After applying exclusion and inclusion criteria, 61 publications were considered appropriate and reasonable for the research, being read in-depth. Finally, only 52 studies presented relevant information for the topic and were synthesized following the defined research questions. During the research, the authors included in the paper other interesting references found in selected articles and important information regarding the role of data in the fight against Covid-19 in smart cities available on the Internet and social media, with the intention to capture both academic and practical perspectives.

The authors' main conclusion suggests that based on their previous expertise in collecting, processing and analyzing data from multiple sources, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The results highlight the importance of open data, data sharing, innovative thinking, the collaboration between public and private stakeholders, and the participation of citizens, especially in these difficult times.

The city managers and data operators can use the presented case studies and findings to identify relevant data-driven smart solutions in the fight against Covid-19 or another crisis.

The performance of smart cities is a social concern since the population of urban communities is continuously growing. By reviewing the adoption of information technologies-based solutions to improve the quality of citizens' life, the paper emphasizes their potential in societies in which information technology is embedded, especially during a major crisis.

This research re-emphasizes the importance of collecting data in smart cities, the role of the diversity of their sources and the necessity of citizens, companies and government synergetic involvement, especially in a pandemic context. The existence of smart solutions to process and extract information and knowledge from large data sets was essential for many actors involved in smart cities, helping them in the decision-making process. Based on previous expertise, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The paper analyzes also these success cases that can be considered models to be adopted by other municipalities in similar circumstances.

Excessive use of work-related information technology (IT) devices can lead to major performance and well-being concerns for organizations. Extant research has provided evidence of the incidence of such problematic IT use in organizations. We extend the understanding of problematic IT use by examining its individual (proximal) and organizational (distal) antecedents.

Drawing from the self-worth theory and the concept of fear of being left behind, we address proximal antecedents that lead to problematic IT use. Drawing from the concept of autonomy paradox, we address distal antecedents of problematic IT use through a positive association with the two proximal antecedents. We report the results of a field study involving 846 individuals who use IT for work. Structural equation modeling was employed to analyze the data.

The results indicate that the proximal antecedents (IT insecurity and fear of missing out) are positively associated with problematic IT use. The distal antecedents (IT use autonomy and involvement facilitation) are positively associated with the proximal antecedents except for the relationship between IT use autonomy and IT insecurity, which was found statistically non-significant. Furthermore, fear of missing out fully mediates the effect of IT use autonomy on problematic IT use, whereas IT insecurity and fear of missing out fully mediate the effects of involvement facilitation on problematic IT use.

The paper theoretically extends the understanding of problematic IT use and identifies novel its proximal and distal antecedents.

The purpose of this paper is to develop a conceptual framework that clarifies the construct of pay secrecy.

Paralleling organizational justice research, two continua of pay information – a distributive continuum about pay raise outcomes and a procedural continuum of pay raise processes – are crossed to produce a 3 × 3 matrix with nine distinct forms of pay communication.

Drawing on the substitutability effect from the organizational justice literature, the matrix highlights the importance of considering how the communication of different types of pay information interact with one another as individuals form pay perceptions.

The matrix framework illustrates that not only information content shapes pay perceptions, but also the extent to which different types of pay information are communicated, and how these different types of information interact. As with any conceptual framework, the current manuscript is limited by a lack of empirical testing.

Managers should be cognizant of the many different ways in which pay information can be communicated. A call is made to reconsider the use of traditionally binary terminology (secret or not) in favor of more accurate descriptions of the nuanced ways in which organizations communicate pay information.

The value of the pay communication matrix lies in the nine unique forms of pay communication arising from the interaction of two different forms of pay information – distributive (outcomes) and procedural (process).

Despite widespread media attention and growing interest from researchers, pay transparency remains an under-studied field of research and its impact on organizational outcomes like job turnover is not well understood. This study explores the impact of pay transparency on job turnover intentions through the mediating effect of perceived organizational support (POS) and organizational justice.

Data from quantitative surveys conducted with 299 employees at four South African organizations with different pay transparency practices were used to test the conceptual model of pay transparency impacting job turnover intentions through the mediators of POS and organizational justice.

The authors found a weak negative relationship between pay transparency and job turnover intentions and the role of the mediating variables was confirmed. Unexpectedly, the role of the organization emerged as a key variable. Controlling for organization type showed that the direct effect of pay transparency on turnover intentions became insignificant, indicating a stronger effect from organizational factors, of which pay transparency practices are just one.

Identifying a contextual (organizational) dimension to pay transparency practices extends the understanding of this concept and has implications for practice. The study also makes a methodological contribution by demonstrating the value of linking respondent data to a particular organization when researching pay transparency.

TikTok social media app has become one of the most popular forms of leisure and entertainment activities, but how hedonic consumption experiences (comprising fantasy, escapism, enjoyment, role projection, sensory, arousal and emotional involvement) of the TikTok app determine users' intention to use the app and its resulting impact on the actual usage behavior remains limited in the information systems literature, especially featuring the hedonic consumption perspective in entertainment industry.

This study employs uses & gratification theory to answer the “why” via predicting the role of hedonic consumption experiences that serve as gratifications to trigger technology acceptance behavior (especially, in form of users' behavioral intention to use the TikTok app and its further impact on usage behavior). This study utilizes the partial least squares-structural equation modeling approach to perform data analyses on 258 TikTok app users.

Our results provide a strong support such that users' playful consumption experiences (i.e. escapism, role projection, arousal, sensory experience and enjoyment) positively influence their intention to use the TikTok app and its resultant effect on users' actual usage of the app. In contrast, fantasy and emotional involvement fail to influence users' intention to use the TikTok app.

To the best of our knowledge, our investigation is one of the first studies to apply the hedonic consumption experiences as potential gratifications that derive users' intention and its subsequent influence on the actual usage of the TikTok app. Our study results would assist marketing and brand managers to redefine approaches and tactics to create effective strategies that implement essential determinants to increase behavioral intention among entertainment service providers.

The purpose of this study is to determine the type of information Library and Information Science professionals share in the WhatsApp groups in Nigeria.

The study adopted a quantitative content analysis research design. With a total of 739 participants, 1,385 posts of six different WhatsApp groups of Library and Information Science professionals for three months were analyzed.

The study found that the most shared information among the Library and Information Science professionals in Nigeria is post on professional information. This demonstrates that librarians are determined to share professional information among them to promote the profession. This was followed by political information basically on the Nigerian Library Association national executives’ election, and job advertisements related to the library. Although a few members violate the rules by posting the kind of information not required in the WhatsApp group, the erring members are quickly called to order and warned by the WhatsApp group administrator.

Professional ties can grow among information specialists and library practitioners through participation in virtual communities such as WhatsApp group. The implication of this work is in showing that social media especially WhatsApp groups can be used as a knowledge sharing mechanism to share timely, current and relevant information among professionals in different occupations.

Findings on the use of WhatsApp group in sharing professional information will inform several other Library and Information Science professionals in other countries of the need to adopt this channel to disseminate timely information related to up-coming conferences, training opportunities, workshops, call for papers and so on among the professionals. The results of this paper are valuable for anyone interested in an avenue to share or receive much quicker and pertinent information that saves the time of professionals in any occupation.
