TED (Technology, Entertainment, Design, www.ted.com/) Talks has been one of the most popular video systems. However, the current TED Talks system expressed its inquired videos as in a two-dimensional (2D) table, which is inconvenient for searching the relationships among videos and tags. This study converts the TED Talks table into a sphere by using optimization techniques to help users search for preferred videos.

There are five phases in this study as follows. Phase 1: Reorganize data of 36 tags and 108 videos; Phase 2: Allocate tags on the TED sphere; Phase 3: Allocate videos on the TED sphere; Phase 4: Develop an online interactive TED retrieval system; and Phase 5: Perform survey and evaluation.

One survey demonstrated that the TED Talks sphere is more convenient for searching videos, as it is more user-friendly because of its graphical user interface, more convenient to use, more useful for retrieving information and can facilitate a more responsive search for users’ preferred videos.

The numbers of tags and videos able to be displayed on a sphere is limited by the capacity of an optimization software and hardware.

The proposed sphere system can be used by a large number of users of TED Talks groups.

This sphere systems can also be applied to other fields which use 2D forms to display the relationships among objects.

This study uses an optimization method to convert a 2D form into a 3D sphere to highlight the relationships among numerous objects.

This paper aims to demonstrate how hospitality management research could benefit from the propositional style of theorizing, and how this approach could expand the scope of research in the discipline.

Developing new theories could provide unique insights and broaden the scope of research in hospitality management. To illustrate the power of proposition-based theorizing, this methodology is applied to the hotel cancellation policies domain.

Using the proposition-based theorizing in the context of cancellation policies, this study provides several propositions that could have broad implications for future research.

The contribution of this paper is threefold. First, the potential benefit of the proposition-based theorizing in the revenue management context of cancellation policies is demonstrated. Second, the theoretical frameworks and insights from the product return policy literature that could enrich future studies on hotel cancellation policies are introduced. Finally, this study conjectures on these theories’ relevance to hotel cancellation policies and consequently on their potential contribution to the scholarly discourse.

The educational environment in Taiwan's primary and secondary schools is becoming increasingly diverse and complex. This study examined the relationship between primary and secondary school principals' working values, organisational climate and organisational adaptation.

Data were collected from the third Teaching and Learning International Survey (TALIS), which targeted 401 principals in Taiwan's primary and secondary schools, conducted in 2018 by the Organisation for Economic Co-operation and Development (OCED). In this study, a structural equation model was constructed.

The results indicated that primary and secondary school principals generally had positive work values, and their schools' organisational climate and adaptation were positive. In addition, the work values, organisational climate and organisational adaptation models showed good fit for a variety of potential variables. Furthermore, the organisational climate had a mediating effect that strengthened the principals' work values and was a major factor in enhancing organisational adaptation. The results suggest that in addition to principals' positive work values, fostering a cooperative organisational climate—such as the perceived level of support from supervisors and the environment—is essential to enhance schools' organisational adaptation.

The principal's work value has a profound impact on the creation of a school's organisational atmosphere, the cohesion of members' consensus and the organisation's contingency decision-making in response to the external environment. This study adduces more diverse recommendations for the development of school affairs.

The purpose of this paper is to examine how the levels of athletic identity influenced the relationships among college experiences, career self-efficacy, and the career barriers faced by semi-professional student-athletes in Taiwan.

Survey data of athletic identity, college experiences (involvement in social, academic, career orientation activities, etc.), career self-efficacy, and career barriers (inherent difficulties in career exploration in a dual student-professional role) were collected from 345 varsity student-athletes in Taiwan sport universities. The conditional process analysis was conducted to test whether the mediating role of career self-efficacy in the association between college experiences and career barriers was dependent on athletic identity levels.

The results indicated that enriching college experiences contributed to fewer barriers regarding career exploration post graduation through high levels of career self-efficacy. Particularly for assorted and social experiences, the indirect effect reduced as the levels of athletic identity increased.

These findings may be applied to athletes who pursue early specialization and students who engage heavily in a specific sport or other co-curricular activities while neglecting the importance of scholastic learning and career exploration. Career counseling practitioners and sport psychologists are advised to take account of athletic identity and contextual specificity while providing career interventions to student-athletes.

This study extends the understanding of the impacts of athletic identity on college student-athletes’ career explorations within a specific sport context.

This study aims to explore booking behavior in an online experiment where the time before the date of stay was controlled for and where action and perceptions were recorded.

An initial pool of 302 students enrolled in various undergraduate and graduate courses in a Midwestern university were asked to participate in the study. Participants were assigned randomly to one of five groups. The treatments differed in the number of days participants had to complete the task of booking a room.

The findings suggest that a sharp increase in the participants' propensity to book occurs during the last week before the date of stay. In addition, the results of the binomial logistic regression provide strong support for the notion that time and the two assessed perceptions are strongly associated with the booking decisions of last minute deal seekers. Participants were more likely to book the closer it was to the date of stay if they thought the hotel was likely to sell out, and if they expected to be offered a better deal later in the process.

This study explored the role of time in hotel room booking decisions. Research suggests that two relevant trends are to be reckoned with when it comes to last minute bookings. First, a growing segment of the travel market is taking advantage of technological advances that facilitate effective deal‐seeking behavior. Second, these patterns of deal‐seeking behavior, and the manner in which consumers respond and adapt to revenue management policies in their attempt to book optimally, are not well understood yet. Accordingly, this study aimed to explore several aspects of last minute perceptions and behavior.

The purpose of this paper is to develop a small data set forecasting method to improve the effectiveness when making managerial decisions.

In the grey modeling process, appropriate background values are one of the key factors in determining forecasting accuracy. In this paper, grey compensation terms are developed to make more appropriate background values to further improve the forecasting accuracy of grey models.

In the experiment, three real cases were used to validate the effectiveness of the proposed method. The experimental results show that the proposed method can improve the accuracy of grey predictions. The results further indicate that background values determined by the proposed compensation terms can improve the accuracy of grey model in the three cases.

Previous studies determine appropriate background values within the limitation of traditional grey modeling process, while this study makes new background values without the limitation. The experimental results would encourage researchers to develop more accuracy grey models without the limitation when determining background values.

The purpose of this paper is to analyse the driving factors of e-books’ illegal downloading and price acceptance from a theoretical perspective that embraces ethical and technological aspects. The diffusion of e-readers and tablets has led to a spate of pirated copies of books.

The proposed model holds that normative and value consciousness, as well as the self-efficacy, the usefulness and the use of the new technology, are determinants of the trend towards free downloads and the maximum acceptable price for e-books. Data are collected from a sample of 227 users of e-book reader devices.

The results provide evidence that individuals are inclined towards piracy when they use and control the technology, whereas value consciousness mitigates illegal downloading and is basic to the individuals’ acceptance of a higher price.

Bearing in mind that the spread of electronic devices has led to an increase in downloads, raising awareness of the norms among individuals is essential if piracy is to be curtailed. In addition, actions aimed at endowing electronic books with value would encourage consumers to pay a higher price for them.

Few attempts have been made to apply ethics theories and the technology acceptance model to the context of e-books’ piracy, and even less effort has been devoted to analyse consumers’ price acceptance in the e-book industry.

The purpose of this study is to attempt to answer the following questions: Are people generous at work places? How often do we see people willing to share, when someone seeks knowledge from them without any expectation? What’s the point in having knowledge when somebody doesn’t share it? Then again, why do firms, reward employees to share their knowledge? ¬ ¬? Does sharing knowledge between people need a commercial acceptance or rewarding inspiration? In firms, people, who do not have relevant work-related knowledge, seek it from others. Thus, this implies that people can either share their knowledge or hoard knowledge or share partial knowledge. This research shows that sharing knowledge has existed for centuries and has been practised through generosity, with proof that the more you share the more you obtain in return. The authors analyse the role of generosity in sharing knowledge by tracing insights from literature, religion, science and modern day management scholarly views, and they show how it can lead firms to succeed. In this paper, the authors will propose a direction for future researchers on how developing generosity helps towards sharing knowledge. They also propose a model of generosity based on literature and its interpretation.

This paper is based on extensive reviews of literature, articles and opinions from scholars. The authors use a keyword protocol to investigate articles from Google scholar and other sources on generosity and knowledge sharing.

This paper finds significant relationships and validated shreds of evidence on how generosity towards knowledge sharing has helped humanity in the past and how generosity can help firms to succeed.

This paper is the first of its kind in trying to explore how developing generosity among people can play a role in facilitating knowledge sharing for firms to succeed. This further suggests a new direction of research for scholars engaged in exploring the role of generosity with a proposed model.
