The nuclear battery technology depends on the spontaneous decay of the atomic nuclei of radioactive isotopes to generate electricity. One of the merits of a nuclear battery is its high-energy density, which can be around ten times higher than that of hydrogen fuel cells and a thousand times more than that of an electrochemical battery. A nuclear battery has an extremely long life and low maintenance and running costs coupled with applications in remote and hostile environmental environments. The rise of silicon technology has intensified research activities in the area of nuclear batteries. The paper aims to present a general overview of a nuclear battery.

This paper presents a general overview of a nuclear battery and will significantly reduce reliance on non-renewable energy source. The requirement for long-lived power supplies have necessitated the pragmatic shift toward the realization of cleaner, safer and renewable energy sources.

Nuclear battery is a safe enabling technology for many applications including military and commercial applications. They have very long operating life under harsh environmental conditions. These cells demonstrate high potential for use in low power applications under a broad range of temperatures.

The nuclear battery technology has been receiving considerable in-depth research for applications that require long-life power sources.

Drawing on self-concept theory, this study evaluates the mediating effects of employees' psychological states on the relationship between human resources (HR) practices and employee engagement.

Through random sampling, 434 customer-contact frontline employees from five-star hotels in Malaysia participated in the cross-sectional survey.

The results produced by the Smart-PLS (partial least squares) indicate that HR practices positively and significantly influence employees' psychological states of safety, meaningfulness and availability. All these psychological states also exert positive influences on employee engagement (organisational and work engagement). Safety and availability mediate the links between HR practices and employee engagement, but not meaningfulness.

HR practices and employees' psychological states are necessary in ensuring positive employee outcomes and improving customer service provision.

The findings contribute to the further extension of self-concept theory and employee engagement by incorporating the mediating roles of employees' psychological states in the relationships between HR practices and employee engagement.

以自我概念理論為依據，本研究擬評估僱員的心理狀態、如何在人力資源做法與員工敬業度之間的聯繫上起著仲介的效應。

透過隨機抽樣法，434名在馬來西亞五星級酒店工作、接觸顧客的一線員工被選參與一個橫斷面調查。

以SmartPLS (偏最小平方)取得的研究結果顯示、人力資源做法正面地影響著員工的安全感、工作給予的意義和感知的組織支援；而且，這些心理狀態，均會對員工的敬業度(對組織的自豪感及對工作的投入)起著正面的影響。另外，安全感和感知的組織支援在人力資源做法與員工敬業度之間的聯繫上、起著仲介之效應；唯工作給予的意義則沒有這個效應。

研究結果進一步伸展了自我概念理論及員工敬業度方面的論述，這是由於本研究把員工心理狀態所扮演的中介角色，納入人力資源做法與員工敬業度的聯繫中。

若要確保積極的員工成果及提供更佳的顧客服務，有效的人力資源做法和正面的員工心理狀態是不可或缺的。

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The purpose of this study is to investigate the impact of family motivation (FM) on promotive voice behavior (VBPm) and knowledge hiding (KH). The study uses moral disengagement (MD) role as a mediator to see how FM shapes moral engagement leading to participate in promotive voice and knowledge sharing.

The hypothesized model was tested using partial least squares structural equation modeling. The authors used convenience sampling and collected data in two phases. The authors have a final sample of 257 faculty members for analysis, with an overall response rate of 42.8%.

Study findings reveal a negative relationship between FM with MD and a positive relationship with VBPm. The relationship between FM and (KHKH results did not show the expected effects. At the same time, mediation of MD between FM and voice behavior and FM and (KHKH show the expected results.

The study finds that family factors have practical consequences for companies in recognizing the value of familial elements in cultivating employee voice and engagement behaviors. Since family is a powerful motivation to work, it provides valuable insights for HRM strategies and organizational studies to encourage employee voice and moral engagement in the workplace. The study is one of the few studies investigating the impact of FM on promotive voice and KH and enhancing the knowledge of mediating role of MD.

Highly committed, motivated and engaged employees assure organizational success and competitiveness. The study aims to examine the association between human resource development (HRD) practices and employee engagement with organizational commitment as a mediating variable.

Data were collected from 760 employees of 13 star-rated hotels comprising 5 (five-star) and 8 (four-star). The data supported the hypothesized relationships. Structural equation modeling was used to evaluate the proposed model and hypotheses. Construct validity and reliability were established through confirmatory factor analysis.

The results indicate that HRD practices and affective commitment are significantly associated. HRD practices and continuance commitment were shown to be non-significantly associated. HRD practices and normative commitment were shown to be non-significantly associated. Employee engagement and organizational commitment are significantly associated. The results further show that organizational commitment mediates the association between HRD practices and employee engagement.

The generalizability of the findings will be constrained due to the research's hotel industry focus and cross sectional data.

The study's findings will serve as valuable pointers for stakeholders and policymakers of the hotel industry in the adoption, design and implementation of proactive HRD interventions to keep highly engaged and committed employees for organizational competitiveness and sustainability.

By evidencing empirically that organizational commitment mediates the nexus between HRD practices and employee engagement, the study extends the literature.

In the current turbulent and highly competitive environment, hotels’ management is under pressure to be innovative and improve their products and services continuously to meet and exceed guests’ expectations. Therefore, the primary objective of this study is to develop and test a framework of the factors that can promote employee psychological safety and help drive employee innovation in hotels in the UK.

A survey questionnaire was constructed and distributed to employees in four- and five-star hotels in the UK. Non-probability convenience sampling was performed in this study. Structural equation modeling (SEM) was used to test the research’s model and hypotheses.

The findings revealed a positive and significant association between psychological safety and employee innovation. Furthermore, psychological safety was found to fully mediate the influence of leader inclusiveness, respectful relationships at work and autonomy on employee innovation. Also, leader inclusiveness and role clarity were discovered to be associated with autonomy, whereas proactive personality was found to be related to employee innovation directly. The outcomes also showed that a proactive personality fully mediates the impact of autonomy and respectful relationships on employee innovation.

This study presents an original chain-mediation model that illustrates the mechanism of how employee innovative behavior can be encouraged by focusing on the mediation of psychological safety. To the best of the authors’ knowledge, this study is among the first attempts to shed light on the role of psychological safety in promoting employee innovation in the hotel sector.
