Circuit reliability has become a growing concern in today’s nanoelectronics, which motivates strong research interest over the years in reliability analysis and reliability-oriented circuit design. While quite a few approaches for circuit reliability analysis have been reported, there is a lack of comparative studies on their pros and cons in terms of both accuracy and efficiency. This paper provides an overview of some typical methods for reliability analysis with focus on gate-level circuits, large or small, with or without reconvergent fanouts. It is intended to help the readers gain an insight into the reliability issues, and their complexity as well as optional solutions. Understanding the reliability analysis is also a first step towards advanced circuit designs for improved reliability in the future research.

The field of tracking tourists’ mobility is a rapidly evolving space. In the eighteen months that it has taken to write this book, many innovations, along with world events such as COVID-19 have emerged, which have required updates to be made to this manuscript. There is no reason to believe that these changes will not continue to be necessary, as technological innovations are likely to occur at a rapid pace and will, no doubt, be utilised by those involved in tourism research. The purpose of this chapter is to attempt to investigate the future of the adaptations that are likely to occur with regards to tourist tracking technology and methods. A near-future gaze is taken as technology and world events are evolving so quickly that it is difficult to predict a future beyond the short term. Techniques such as physiological tracking, emergency management, indoor positioning, machine learning and artificial intelligence are assessed along with the future of ethical research conduct. A summary is also made where the pros and cons of each research method is assessed and finally, future research needs are highlighted.

AbstractBlockchain technology has completely changed the area of cryptocurrency with a Peer-to-Peer system named Bitcoin. It can provide a distributed, transparent and highly confidential database by recording immutable transactions. Currently, the technique has obtained great research interest on other areas, including the Internet of vehicles (IoVs). In order to solve some centralized problems and improve the architecture of the IoVs, the blockchain technology is utilized to build a decentralized and secure vehicular environment. In this survey, we aim to construct a comprehensive analysis on the applications of blockchain in the IoV. This paper starts with the introduction of the IoVs and the blockchain. Additionally, some existing surveys on the blockchain enabled IoVs are reviewed. Besides, the combination of the blockchain technology and the IoVs is analyzed from seven aspects to describe how the blockchain is implemented in the IoVs. Finally, the future research directions related to the integration are highlighted.

AbstractPrevious research reported that corvids preferentially cache food in a location where no food will be available or cache more of a specific food in a location where this food will not be available. Here, we consider possible explanations for these prospective caching behaviours and directly compare two competing hypotheses. The Compensatory Caching Hypothesis suggests that birds learn to cache more of a particular food in places where that food was less frequently available in the past. In contrast, the Future Planning Hypothesis suggests that birds recall what-when-where features of specific past events to predict the future availability of food. We designed a protocol in which the two hypotheses predict different caching patterns across different caching locations such that the two explanations can be disambiguated. We formalised the hypotheses in a Bayesian model comparison and tested this protocol in two experiments with one of the previously tested species, namely Eurasian jays. Consistently across the two experiments, the observed caching pattern did not support either hypothesis; rather it was best explained by a uniform distribution of caches over the different caching locations. Future research is needed to gain more insight into the cognitive mechanism underpinning corvids’ caching for the future.

Purpose – Prison violence generates much public interest with concerns for the financial costs, staff safety and public safety. The purpose of this paper is to explore the experience of riotous behaviour from the perspective of prisoners in a maximum secure adult prison. It also seeks gather information and to generate discussion on areas for future research. Design/methodology/approach – A purposive sampling method and in-depth semi-structured interviews were carried out. Interpretative phenomenological analysis identified super ordinate themes and related sub-themes within the participants’ narratives. Emergent themes were then considered in relation to the theories and concepts that underpinned and connected them. Findings – Super ordinate themes emerged centred around the subject of social processing and relationships. Prisoners emphasised the role of prisoner-staff relationships in feeling valued as part of the social structure and considered riotous behaviour the best method of communication at that time. Social comparison highlighted the value they placed in being part of the prisoner culture and the nostalgic nature of the riotous behaviour for them. It lends support to earlier theory on prison adjustment and social psychological explanations for rioting. Research limitations/implications – It is not assumed that the findings of this study can be universally applied given the sample size and the idiosyncratic nature of participants’ experiences. This research may provide greater insight into the motivational factors related to individuals involved in riotous behaviour. With such insight prison staff may be more able to consider whether prisoners’ needs are being sufficiently met to help prevent such behaviour in the future. Practical implications – This research may help inform training on the identification and management of potential riots. With insight into the individual motivational factors prison staff may be more able to consider whether prisoners’ needs are being sufficiently met to help prevent such behaviour in the future. Originality/value – This paper reports on the prisoners’ individual experience of being involved in riotous behaviour. Due to the paucity of literature on this behaviour, this exploratory study is intended to add to existing knowledge.

Objective – To study the ways in which novice academic librarians’ perceptions of librarianship develop from the time they decide to attend library school through their first 6 to 24 months of library work. Design – Grounded theory method utilizing two qualitative research techniques: one-on-one, face-to-face interviews and document analysis. Setting – The libraries of three Texas universities, three Texas four-year colleges, and one Texas community college. Subjects – 12 professional academic librarians who graduated from eight different graduate schools. Participants were 6 to 24 months into their professional careers and had little or no pre-professional experience. Methods – The researchers sought participants through mailings, emails, electronic mailing list postings, and referrals from other participants. They conducted a small pilot study with two novice librarians to refine their research methodology. The researchers interviewed additional participants and analyzed the interview transcripts until categories of interest were identified and saturated. Saturation occurred at 12 participants, not including the pilot participants. Each interview was 30-45 minutes. The researchers recorded the interviews and systematically coded the transcripts using activist imagery. Four of the participants gave the researchers their “statement of purpose” essay that they used when applying for graduate school. These documents were also discussed with participants and analyzed. Main Results – From the data they collected, the researchers identified six categories of interest regarding librarians’ perceptions of librarianship: deciding upon a career, experiencing graduate school, continuing education, defining the work, evaluating the work, and (re)imagining the future. In considering librarianship as a career, the participants had not been entirely sure what it entailed, but they utilized what they did know about libraries and librarianship to generally deem the profession solid, safe, and/or noble. They had further explored librarianship to determine its compatibility with their personal characteristics. Such personal reflection had led participants to graduate school where they gained a real understanding of librarianship. The participants had not generally found graduate school to be academically challenging. They had also valued practical over theoretical instruction. Once in the workplace, the participants noted the value of continuing education to strengthen the skills they had learned in graduate school. Participants benefitted the most from informal mentoring and on-the-job training, i.e. “learning by doing” (p. 192). As novice librarians, the participants had learned to feel their way around their job expectations and note the differences between their responsibilities and those of paraprofessionals in the library. As the novice librarians further defined their work, they had also learned that academic librarianship is the sum of many parts, including collaboration with peers. In evaluating their work, the participants noted that they had come to distinguish “real” academic library work, that which uses their expertise and helps society, from “other” work such as clerical work (pp. 195-196). The sixth and final category was “(re)imagining the future.” Most of the participants predicted having advanced as academic librarians in the next five years but were otherwise unsure about what their futures would hold. Conclusion – The researchers made a number of valuable observations in their work with novice librarians. As the step of deciding upon a career seemed to be a murky quest, they thought it would be helpful to analyze public opinion of librarianship and use that information to offset misperceptions about what librarians do. This might help those considering librarianship to make informed and conscious decisions. The study data also provided insight into graduate school. The fact that the participants did not consider graduate school to be rigorous concerned the researchers. They feared that librarians entering the field might not deem it a serious profession. Because the participants favored practical over theoretical classes, the researchers thought it important for graduate schools to teach theoretical concepts in a way that is more satisfying to students. They felt that other applied fields, such as nursing, might provide examples of how to do so. The researchers also noted that graduate schools could do more to prepare students for life on the job. As new librarians reported favouring “real” work over “other” work, the researchers felt that students should hear it first in graduate school that all the work librarians do is an important and necessary part of academic librarianship. As most participants were uncertain about what their futures as academic librarians might look like, the researchers thought that graduate school professors should address that issue as well. Data from this study also gave insight into how employers might best serve new librarians. The researchers suggest looking to new teacher induction programs to get ideas for orienting new librarians to the profession. Orientation might include a combination of formal and informal techniques such as peer mentors, peer observation, new librarian training, and new librarian handbooks in the first year of employment. Finally, the researchers proposed ideas for future research. They believe it might be helpful to study experienced academic librarians or new public librarians for comparison to this study.

This chapter contributes to defining a common research agenda on organizational trust, first by content-analyzing scholarly recommendations for future research published between 2007 and 2011 across 347 articles and 58 social science journals and second by reviewing the latest developments in trust research published between 2012 and 2015 across 111 articles and 31 top-tier management journals. This content analysis of scholarly recommendations yields an emergent organizing framework that offers systematic insight into the trust community’s beliefs about how the field should move forward, while the review of the latest developments in the field provide insight into whether these recommendations have recently been followed up on, or whether research has developed in previously unanticipated directions. The chapter concludes with suggestions on how individual researchers and the trust community as a whole can use and build on these findings to help advance the field.

Abstract. Background: Suicide can have a lasting impact on the social life as well as the physical and mental health of the bereaved. Targeted research is needed to better understand the nature of suicide bereavement and the effectiveness of support. Aims: To take stock of ongoing studies, and to inquire about future research priorities regarding suicide bereavement and postvention. Method: In March 2015, an online survey was widely disseminated in the suicidology community. Results: The questionnaire was accessed 77 times, and 22 records were included in the analysis. The respondents provided valuable information regarding current research projects and recommendations for the future. Limitations: Bearing in mind the modest number of replies, all from respondents in Westernized countries, it is not known how representative the findings are. Conclusion: The survey generated three strategies for future postvention research: increase intercultural collaboration, increase theory-driven research, and build bonds between research and practice. Future surveys should include experiences with obtaining research grants and ethical approval for postvention studies.
