The purpose of this study is to investigate the effects of telepresence while using a smartphone-based virtual reality system (SBVR) to explore a hotel virtually and to determine the influence of this immersive experience on the booking intention of the potential customer.

Within the scope of this study, a conceptual research model was developed which covered utilitarian and hedonic aspects of the user experience of SBVRs and showed their relevance for the booking intention. A virtual reality application was programmed especially for the study, in which the test persons were able to virtually explore a hotel complex. A total of 569 people participated in the study. A questionnaire was used for the data collection. The structural equation modelling and hypothesis verification were carried out using the partial least squares method.

The immersive feeling of telepresence increases the perceived enjoyment and usefulness of the potential customer. In addition, the user's curiosity is aroused by the telepresence, which also significantly increases the perceived enjoyment as well as the perceived usefulness. The hedonic and utilitarian value of the virtual hotel experience increases the probability that the customer will book the travel accommodation.

The virtual reality application developed for the study is based on static panoramic images and does not contain audio-visual elements (e.g. sound, video, animation). Audio-visual elements might increase the degree of immersion and could therefore be investigated in future research.

The results of the study show that the SBVR is a suitable marketing tool to present hotels in an informative and entertaining way, and can thereby increase sales and profits.

For the first time, this study investigates the potential of SBVRs for the virtual product presentation of hotels and provides empirical evidence that the availability of this innovative form of presentation leads to a higher booking intention.

The Israeli National Police began to implement community policing on a large scale in January of 1995. In this paper we describe the main findings of a three year national evaluation of community policing in Israel that was initiated by the Chief Scientist’s office of the Israeli police in the Fall of 1996. When community policing was envisioned and planned in Israel it was seen as part of a total reformation of the Israeli police in structure, philosophy and action. Our research suggests that this broad idea of community policing was not implemented in Israel, and indeed the program of community policing was found to lose ground during the course of our study. While community policing did have specific impacts on the Israeli police, it did not fundamentally change the perspectives and activities of street level police officers. We explain the difficulties encountered in the implementation of community policing in reference to three factors: the speed of implementation of the program; the resistance of traditional military style organizational culture within the Israeli police to the demands of community policing models; and a lack of organizational commitment to community policing. In our conclusions we argue that these barriers to successful community policing are not unique to the Israel case, and are indeed likely to be encountered in the development of community policing in many other countries.

Melvin Seeman (1989) has recently stated that nowadays the concept of alienation carries an antiquated meaning which is quite in contrast to its importance in the 1960s. There seems to be much evidence for a fading romance with alienation in the social sciences. I have continued Seeman's search for articles that have appeared between 1978 and 1982 in leading social science journals until 1989. There was only one major reference, however, a quite important one by Kai T. Erikson in his presidential address to the American Sociological Association in 1985. Contrary to these disappointing observations Seeman suggests that alienation is leading an underground life in contemporary research and theory. According to his assessment this theme survives because the assumptions involved in the tradition of the alienation motif are indispensable for critical analysis in sociology and psychology.

High prevalence of violence against persons with disabilities (PwDs) has prompted a steady growth of training aimed at equipping PwDs with personal safety skills. This paper aims to examine the efficacy of safety trainings for PwDs.

A search of relevant electronic databases was conducted to shortlist peer-reviewed literature on empirically evaluated safety trainings for PwDs, between January 2010 and August 2020 with the defined inclusion criteria.

Six safety programmes were reviewed. Data analysis revealed key themes related to programme modifications for accessibility; fit of intervention to disability type; PwDs’ learning needs; and the context of disability abuse in designing intervention pathways.

PwDs can benefit from and contribute to safety training, if programmes are adequately modified to support their learning and participation. Future studies can target disability abuse by known persons; different disability groups; and generate longitudinal data to strengthen validity of programme efficacy.

This study examined the association between media consumers' attitudes toward COVID-19-related content on mainstream, on-demand and social media and trust in the government's ability to handle the pandemic crisis.

The study is based on an online survey of a representative sample of 1,005 Israelis aged 18 and over and focused on consumers' perceptions of media contents as a source of information, social solidarity, criticism and anxiety.

Findings indicate that mainstream media were the primary source of pandemic information. A positive association was found between perceptions of mainstream media as a source of criticism and trust in government's actions. This association was negative regarding social and on-demand media. The more mainstream media contents were perceived as anxiety evoking, the lower participants' trust in government's actions. A positive association was found between perceptions that social media encouraged social solidarity and trust in governmental action.

Policymakers should take into consideration that various media operate synergistically to continually construct reality.

This study focuses on consumers' perceptions of COVID-related media contents, which are especially important in the current era of media outlet proliferation, distribution and impact on the government. The unique contribution is in the integrated application of media malaise theory, virtuous circle theory and echo chamber theory to explain the correlation between media consumption and public trust during a global crisis in the era of diverse media outlets.

Markets for public contracting are in the process of transition. Various public/private partnership arrangements replace conventional purchasing, especially within the local and regional government area. Municipal entities may not be in a position to define their needs up-front because they would not have the overview of what the market may have to offer. So one should ask: Is the traditional ban-on-negotiations in mandatory tender procedures (sealed bidding) - such as it is in EU public procurement law - counter-effective to genuine best value for public money? The article displays significant differences between European Union (EU) law, U.S. law and other regimes such as United Nations Model law, The World Trade Organisation’s Government Procurement Agreement (WTO/GPA), The International Bank for Reconstruction and Development (IBRD), and the NAFTA (North American Free Trade Agreement). New avenues for public/private demand a new agenda and the recent EU 2004 directive scheme attempts to respond to the market challenges. The author accepts that the new directive on public contracting facilitates a more smooth approach than in current EU law with regard to high-tech complicated contract awards, but questions whether the ’competitive dialogue’ really can afford tailor-made solutions to cope with long-term public/private partnership arrangements of the kind now spreading all over Europe

This paper aims to make a systematic review of the manpower prediction model of the construction industry. It aims to determine the forecasting model's development trend, analyse the use limitations and applicable conditions of each forecasting model and then identify the impact indicators of the human resource forecasting model from an economic point of view. It is hoped that this study will provide insights into the selection of forecasting models for governments and groups that are dealing with human resource forecasts.

The common search engine, Scopus, was used to retrieve construction manpower forecast-related articles for this review. Keywords such as “construction”, “building”, “labour”, “manpower” were searched. Papers that not related to the manpower prediction model of the construction industry were excluded. A total of 27 articles were obtained and rated according to the publication time, author and organisation of the article. The prediction model used in the selected paper was analysed.

The number of papers focussing on the prediction of manpower in the construction industry is on the rise. Hong Kong is the region with the largest number of published papers. Different methods have different requirements for the quality of historical data. Most forecasting methods are not suitable for sudden changes in the labour market. This paper also finds that the construction output is the economic indicator with the most significant influence on the forecasting model.

The research results discuss the problem that the prediction results are not accurate due to the sudden change of data in the current prediction model. Besides, the study results take stock of the published literature and can provide an overall understanding of the forecasting methods of human resources in the construction industry.

Through this study, decision-makers can choose a reasonable prediction model according to their situation. Decision-makers can make clear plans for future construction projects specifically when there are changes in the labour market caused by emergencies. Also, this study can help decision-makers understand the current research trend of human resources forecasting models.

Although the human resource prediction model's effectiveness in the construction industry is affected by the dynamic change of data, the research results show that it is expected to solve the problem using artificial intelligence. No one has researched this area, and it is expected to become the focus of research in the future.

The purpose of this review is to draw out patterns of information seeking behavior of graduate students as described in the empirical research published from 1997 to the present.

A systematic search of databases for studies on information behavior and graduate students was employed in order to retrieve studies for a systematic review. Common themes that emerged from the literature were synthesized into a discussion of behavior patterns. Additionally a study quality analysis was conducted for all retrieved studies using a critical appraisal checklist for library and information research.

This review revealed that graduate students begin their research on the internet much like any other information seeker, consult their faculty advisors before other people, and use libraries in diverse ways depending on the discipline studied. Additionally differences were noted between international and home students, and doctoral and master's students.

The findings of this review indicate that information behavior research conducted on graduate students should delineate between masters' and doctoral students. Further, the findings may inform both academic librarian and faculty practice as to how to assist students with their research by helping them to understand how students typically approach research and how other institutions address common issues with special populations, such as non‐native speakers and distance learners.

No comprehensive review of information behavior studies, encompassing only the behaviors of graduate students has been conducted to date.
