Internet of Things-based environments pose various challenges due to their anytime/anywhere computing, and the efficient cryptographic based key management is one of the major challenges in Internet of Things. The key management life cycle consists of initialization, key generation, key registration, key backup, key update, key recovery, and key revocation. Our contribution in this paper is to summarize the state-of-the-art key management schemes and techniques in different scenarios, such as mobile ad hoc networks, wireless sensor networks, and the Internet of Things environments. Further different issues related specifically to the Internet of Things environment are discussed and the causes and effects pertaining to the security breach for Internet of Things are identified. Furthermore, in this research work, we develop a novel permutation of threshold and identity-based key management schemes for the Internet of Things environment and have proposed future directions to counteract the attacks on confidentiality, integrity, authentication, and availability of security services in the Internet of Things environment and identified the two key management schemes, that is, identity and threshold schemes for Internet of Things, to resolve Internet of Things key management issues and maximum possible security services effective implementation. We evaluate our scheme with the help of mathematical and statistical techniques.

Therefore, firms invest millions of dollars in innovation activities to ensure long-term business sustainability. Similarly, consumer concerns have increased dramatically over the past years. Thus, brand loyalty has become a top priority for firms and consumers. In this background, this research examines how firms’ innovation activities translate into consumer brand loyalty to assure business sustainability in Asian markets, particularly China, Pakistan, and Indonesia.ObjectivesThis study’s specific objectives are to comprehend the concept of firms’ innovation activities and their effect on the brand prototype. Examine the effect of the brand prototype on global brand preference, recommendation, and loyalty among Asian consumers. Find out the impact of brand preference on brand recommendations and the influence of brand recommendations on brand loyalty among Asian consumers.Materials and methodsA total of 814 consumers from Asian countries participated in this study, and structural equation modeling was used to analyze the data.ResultsThe findings indicate that firms’ innovation activities, such as processes, products, and store environment, positively influenced the brand prototype, thereby increasing consumer brand knowledge. Likewise, brand prototype contributes to developing brand preference, brand recommendation, and brand loyalty among Asian consumers. Lastly, consumer brand preference significantly influenced brand recommendation, which positively improves consumer brand loyalty in Asia.ConclusionThis study concluded that Asian consumers have favorable perceptions of firms’ innovation activities, which influences their ability to develop brand prototypes to increase consumer brand knowledge. Similarly, brand prototype fosters brand preference, recommendation, and loyalty. Likewise, favorable brand preference encourages consumers to recommend the brand to others, strengthening brand loyalty. Thus, firms should invest in innovation activities to strengthen consumer brand loyalty in Asian markets. Consequently, this study may assist multinational corporations in increasing their business volumes and market shares in Asia.Managerial recommendationsThis study provides important managerial recommendations. The findings revealed that global managers can develop and implement several branding strategies for sustaining their businesses in the Asian environment.

Research conducted with ethical values is the need of modern world and great benefit to the society in general and human beings in particular. Clinical research basically focuses on improving human health individually by improving current trends, methodologies and identifying innovative methods of treatment. Public health research is mainly concerned with the health of the entire populace. No standard rules can be formulated for conducting any form of research ethically; however following some basic ethical values can assure ethical conduct of research. In any research study whether that is public health research or clinical research, the importance is need to be to recognize an ethical standard that respects individuals autonomy and communitys wellbeing. Ethical values in research studies can be achieved by requiring individuals and communitys collective collaboration for the protection of individuals autonomy, dignity and wellbeing.

The regression model is generally utilized in several fields of study because of its applications. Regression is an extremely incredible approach; it builds up a connection between dependent and independent variables. We have addressed a powerful computational model by utilizing dengue information joined with fuzzy multiple linear regression. Information is accumulated on dengue fever through the survey. This paper is centered on the comparison of the crisp method with fuzzy multiple linear regression, and then, the utilization of a fuzzy multiple regression method is explained after the comparison. We have used multiple regression and then converted the said technique into three fuzzy cases. The effectiveness of the fuzzy multiple regression model is measured by numerical computation and comparison of both techniques. 2020 Mathematics Subject Classification.

Since the creation of Pakistan the foundation of the Idea of Pakistan has been a matter of academic and political debate. There is a difference between the two spheres. The academic debate allows a room to discuss popular and unpopular ideas and respect the contrary views. The ideology of Pakistan, political system of Pakistan and the constitution of Pakistan have always been discussed and debated amongst scholars. The purpose of this research is to explore the famous presidential address of Allama Iqbal at the annual session of Muslim League in 1930. There are many perceptions about the address delivered by Iqbal, such as he demanded a separate homeland for Muslims of India or not. This research will explore the facts of Iqbal’s speech of Allahabad and will attempt to do justice to his words which have been misinterpreted by some spheres.

The COVID-19 pandemic has caused a global crisis that particularly hit employment globally. Due to the economic crisis, many small businesses attempted to minimise their expenses by either closing or downsizing. During such organisational situations, the employees face negative workplace attitudes that lead to knowledge hiding and affect team performance. This study examines negative attitudes and their effect on team performance. Further, this study examines the mediating effect of knowledge hiding and moderating the role of servant leadership. Through a multi-time data collection approach, the authors obtained 363 responses from the education sector in China during the COVID-19 pandemic. PROCESS Hayes model 1 and 4 were used for mediation and moderation analysis. Results show that job insecurity, cynicism, and role stress are significant forces behind knowledge-hiding behaviour. Furthermore, the knowledge hiding behaviour adversely affects task performance. Servant leadership shows a buffering effect on knowledge hiding behaviour caused by negative workplace attitudes. This is one of the first studies in the South Asian environment to examine the association between employees’ negative attitudes and task performance using knowledge hiding as a mediator and servant leadership as a moderator in the COVID-19 scenario. Lastly, the paper concludes with a consideration of its theoretical, practical implication and future direction.

The purpose of this study is to examine the link between English foreign language teacher’s professional identity and employee success via mediating role of critical thinking. Further, we examined the moderating role of leader motivational language between employee professional identity and critical thing and also indirect effect on employee success via critical thinking. We collected data from Chinese MNC’s school by using time lagged study design. We used hierarchical linear regression for direct hypotheses and Hayes PROCESS model’s for mediation, moderation, and mediation moderation analysis. The results show that there is positive relation between employee’s professional identity and teacher’s success. Further, critical thinking mediates the link between professional identity and employee success. The results of the moderated mediation analysis show that critical thinking mediated the interaction of employee’s professional identity and leader’s motivational language on teacher’s success.

This study aims to elaborate on how work-life balance practices influence organizational cynicism through the mediation effects of person-job fit. We collected data from 331 nurses through a self-administered survey, and we tested our hypothesized model through partial least square structural equation modeling techniques using SmartPLS software. The findings revealed that WLB practices influenced OC negatively and PJF positively. We further found that PJF negatively influenced OC and mediated WLB practices’ effect on OC. These findings imply that nurses should be provided WLB practices to meet their job and home responsibilities and thus have a less cynical attitude toward the organization.

Reading habits among young generation is going to declining and culture of reading books is modified to modern methods of communication like browsing social sites and internet, playing on cell phones and watching T.V. This era modernization has taken away the youth from reading habits. It is important that the young generation learns about the rich Urdu literature including Urdu fiction in which several writers have significantly contributed. The emergence of Urdu literature facilitated the expansion of Urdu language. Fiction writers try to indicate important weaknesses of the society, cultural traditions, and norms, so as to find out the solutions to these issues. There were so many fictional works in Urdu literature having done during the progressive and independent movement. “ANGARAY” is a collection of fictional short stories authored by four young writers who had a progressive approach and tried in their own way to bring forth several social issues through their work at the time British India. This paper attempts to present a brief history of this collection and the consequences emerging out of its publication at that time. The study is reviewed and analyzed the criticism on selected short stories of subsequent publication. The study found that the readers would find the ideas and views of the four writers in the present time may provide them some relief from the opposition they faced on publication of their work.

In this study, we examined the impact of energies of 2.54 keV and 5 keV displacement cascades in molybdenum (Mo) using an atomistic simulation at 300 K. The simulation was carried out using machines learning developed spectral neighbor analysis potential (SNAP). We computed displacement threshold energy (E_d), vacancy formation energy (E_v^f), interstitial formation energy (E_i^f), interstitial cluster formation energy (E_cf^i), activation energy barrier of interstitial〖 (E〗_ai), activation energy barrier of vacancy (E_aV), elastic properties, i.e., shear, bulk, young's modulus, poison ratio. The simulations for primary displacement cascades were performed over a statistical average of 20 independent molecular dynamics simulations such that peak time and the surviving number of defects are inversely proportional to the incident energy of primary knock-on atoms (EPKA). Additionally, it is established that the number of clusters (Nclusters) during displacement cascades is directly proportional to EPKA. Furthermore, it was revealed that the number of interstitial clusters is higher than the number of vacancy clusters. This research will provide atomic insight into the interactions of defects in Mo for the development of structural materials for high temperature applications.
