The suffciency conditions are derived for exact image reconstruction of a 3D ROI from projections acquired with a reduced helical scan over an angular range considerably smaller than that required by image reconstruction in, e.g., the conventional long object problem, for which the scanned angular range is often more than 2π. ROI reconstruction is investigated by a recently developed filtered-backprojection algorithm that can make use of data acquired with a reduced helical scan. Preliminary numerical studies demonstrate and validate the ROI reconstruction. This work may have significant practical implications because a reduced scan in CT often translates to reduced motion artifacts and reduced radiation dose delivered to the subject.

By building on compensation literature, the current study explored and identified the ties between workers’ competencies, corporate cultures, and compensation schemes. These schemes were typically the subject of literature on the factors dealing with the implementation of incentive systems for pay for performance (PFP) or problems that can lead to a PFP system’s failure. Unfortunately, when it comes to research that HR education practitioners may do, the literature has been scarce. It shows which organizational elements might be necessary to examine when deciding whether a PFP or an alternative compensation program is acceptable. This study aimed to add insight into this gap in research. The findings of this study showed from the use of data from 385 American employees in the manufacturing industry that there are significant relationships statistically between employee competencies and organizational cultures and those findings can be corroborated with existing researches, suggesting compensation schemes were related to multiple types of competence organizations and different organization cultures, thus adding meaningfully to the current literature.

Purpose The authors review the concept of building relationships with Shapeholders,: a broad group of players that have no financial stake in the company yet can substantively influence it. The process for doing this is the subject of a new book by Mark Kennedy, Shapeholders: Business success in the age of social activism. Design/methodology/approach The authors examine Mark Kennedy’s framework for managing the firm’s shapeholders, a model composed of seven basic steps (7A’s): Align with a purpose, Anticipate, Assess, Avert, Acquiesce, Advance common interests, and Assemble to win. Findings Managing corporate reputation in alliance with enlightened shapeholders is a potential defense against self-aggrandizing schemes to wantonly maximize shareholder value in the short run. Practical implications Managing shapeholders is part of the messy democratic process that works when power is apportioned fairly among those affected by a firm’s decisions, and this process underpins the winning business models of true market leaders. Social implications Stakeholders previously discredited as mere “mosquitos” have gained new power, particularly when their legitimate concerns and unfair treatment resonate with the interests of a significant segment of the public and influential shapeholders. Originality/value Shapeholders can create enormous opportunities for smart managers capable of effectively engaging with them.

PurposeThere are ethical, legal, social and economic arguments surrounding the subject of autonomous vehicles. This paper aims to discuss some of the arguments to communicate one of the current issues in the rising field of artificial intelligence.Design/methodology/approachMaking use of widely available literature that the author has read and summarised showcasing her viewpoints, the author shows that technology is progressing every day. Artificial intelligence and machine learning are at the forefront of technological advancement today. The manufacture and innovation of new machines have revolutionised our lives and resulted in a world where we are becoming increasingly dependent on artificial intelligence.FindingsTechnology might appear to be getting out of hand, but it can be effectively used to transform lives and convenience.Research limitations/implicationsFrom robotics to autonomous vehicles, countless technologies have and will continue to make the lives of individuals much easier. But, with these advancements also comes something called “future shock”.Practical implicationsFuture shock is the state of being unable to keep up with rapid social or technological change. As a result, the topic of artificial intelligence, and thus autonomous cars, is highly debated.Social implicationsThe study will be of interest to researchers, academics and the public in general. It will encourage further thinking.Originality/valueThis is an original piece of writing informed by reading several current pieces. The study has not been submitted elsewhere.

Purpose The purpose of this paper is to examine the effects of interaction techniques (e.g. swiping and tapping) and the range of thumb movement on interactivity, engagement, attitude, and behavioral intention in single-handed interaction with smartphones. Design/methodology/approach A 2×2 between-participant experiment (technological features: swiping and tapping×range of thumb movement: wide and narrow) was conducted to study the effects of interaction techniques and thumb movement ranges. Findings The results showed that the range of thumb movement had significant effects on perceived interactivity, engagement, attitude, and behavioral intention, whereas no effects were observed for interaction techniques. A narrow range of thumb movement had more influence on the interactivity outcomes in comparison to a wide range of thumb movement. Practical implications While the subject of actual and perceived interactivity has been discussed, the issue has not been applied to smartphone. Based on the research results, the mobile industry may come up with a design strategy that balances feature- and perception-based interactivity. Originality/value This study adopted the perspective of the hybrid definition of interactivity, which includes both actual and perceived interactivity. Interactivity effect outcomes mediated by perceived interactivity.

Practical Implications

Purpose – The increasing frequency with which food and beverage producers feature in mainstream media, including television cooking shows, provide opportunities and pitfalls for using media to promote artisan food and beverage businesses. The purpose of this paper is to evaluate these, as experienced by a group of food and beverage producers who appeared on the popular Australian television show, Gourmet Farmer. Design/methodology/approach – Findings are based on semi-structured interviews with 14 of the producers featured on the show, plus textual analysis of relevant segments of the show. Findings – While all of the producers felt that food television offered a good promotional tool, those who were most familiar with the practices of media production and whose businesses offered experiences through which viewers could access (or imagine) a “taste” of the Gourmet Farmer life tended to be more satisfied than those who were less familiar with the practices of media production and who expected a greater focus on their products and production practices. Practical implications – The development of media skills is essential for artisan producers to get the best outcomes when using media to promote their businesses. Originality/value – The experiences of food and beverage producers using food television to promote their businesses have not previously been the subject of thoroughgoing research. This paper offers new insights into how artisan producers can best capitalize on the opportunities offered by food media.

In recent years, the number of studies in tourism using the eye tracking technique has increased and started generating valuable information for both academics and the industry. However, there is a gap in the literature concerning systematic reviews focused on recent articles and their findings. Thus, the aim of this study is to close this gap by systematically analysing 70 research papers tackling the subject of eye tracking in tourism and published in highly ranked tourism journals. The study identifies the most popular topics and trends for eye tracking research, as well as the most used types of visual stimuli, such as exhibitions, restaurant menus, promotional pictures or websites. The study also details on measurements specific for the analysis of eye tracking data, including fixations, saccades and heat maps. Results are emphasized along with their theoretical and practical implications. In addition, we highlight the lack of the use of dynamic stimuli in the existing literature and suggest further research directions using the eye tracking technique.

Purpose This paper aims to examine the challenges to sustaining corporate culture in a world of hybrid working. Design/methodology/approach This paper is a review of current literature on the impact of remote and hybrid working on white-collar employees. Findings There is little consensus on whether remote/hybrid working will harm or strengthen corporate culture. Research limitations/implications The viewpoint is a subjective assessment of a limited number of articles on the subject Practical implications It is not entirely clear how those responsible for corporate culture can act on the findings. Social implications In a world in which corporations are experiencing a shortage of talent, how they handle corporate culture will be increasingly important. Originality/value While much has been written on the impact of remote working, this viewpoint takes the original view that strong corporate cultures rely more on the attitudes and actions of individual employees that company programs or initiatives.
