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.

The positive outcomes demonstrated in programme efficacy trials and the apparent ineffectiveness of programmes in community settings have prompted investigators and practitioners to examine implementation fidelity. Critically important, but often overlooked, are the implementers who deliver evidence‐based programmes. This article distinguishes fidelity at the programme level from implementer fidelity. Two components of implementer fidelity are defined. It is proposed that implementer adherence and competence are related but unique constructs that can be reliably measured for training, monitoring and outcomes research. Observational measures from a school‐based preventive intervention are used to illustrate the contributions of implementer adherence and competence. Distinguishing implementer adherence to the manual from competence in programme delivery is the next step in child mental health programme implementation research.

The paper provides a Canadian perspective on the use of psychotropic medication in the management of problem behaviours in adults with intellectual disabilities in Canada. Psychotropic medication and intellectual disabilities were explored in the context of Canadian health and social services, clinical practices, medical training and factors that have shaped these over the past few decades. Informal physician intellectual disabilities networks and the newly formed Canadian Network of the National Coalition on Dual Diagnosis provided the opportunity to survey the use of psychotropic medication for problem behaviours across the country. Geographic, political, cultural and other influences on the development of health and social services are described, as well as training requirements for physicians. Survey responses were received from all provinces and represented clinicians in mental health multidisciplinary teams, health and social services ministry representatives, agency staff (up to executive director level) and family members of individuals with intellectual disabilities. Psychiatry and family medicine perspectives of the authors from working in Canada and the UK with people with intellectual disabilities presenting with problem behaviours are described. In Canada there are no national, provincial or territorial policies or guidelines on use of psychotropic medication for the management of such behaviours. There are no requirements for physicians prescribing these medications to have training in the care of people with intellectual disabilities. Services for people with intellectual disabilities and behaviour problems in Canada appear to be more crisis‐reactive than those in the UK.

This study examined the effectiveness of a 4.5-day service leadership program for students from Chinese universities using objective outcome evaluation. The participants were assessed before and after the program, with two post-test measurements (immediate assessment and assessment 12 days after the completion of class learning). At pretest and two posttest time points, the participants completed a questionnaire measuring positive youth development, service leadership qualities and beliefs, and life satisfaction. Results showed that students’ performance in both the immediate posttest and follow-up test was better than that in the pretest. Despite the limitations of the one-group pretest-posttest design, results suggest that the curricular-based service leadership program was effective to promote students’ positive youth development, service leadership qualities and beliefs, as well as life satisfaction, and the effectiveness maintained a short period after the class had ended. While the existing findings are promising, these findings should be replicated in the future.

The purpose of this paper is to reveal the mechanism underlying many inexplicable phenomena observed in social organizations and human history by using the general systemic yoyo model.

Such traditional tools as laboratory experiments, calculus‐based methods, quantitative reasoning of microeconomics, and set‐theoretical logic are collectively employed to present a brand new method for the study of many unsettled problems in the research of civilizations.

Among a whole series of open problems, novel explanations are provided for important questions like: how do civilizations or cultures form? Why did Western democracy not originate in Eastern Asian or other parts of the world? Why does each blown‐up that it bridges a transition between organizational expansion and contraction represents a weakest link in the evolution of a social entity? Why are there nation states within a civilization? Why is the Western civilization having multiple centers or core states, while the Sinic civilization has one core state and the Islamic civilization does not seem to have any core states? How can policy makers separate civilizations from each other?

This work presents how systems science in general and the systemic yoyo model in particular can bring forward tangible results in social science with solid scientific merits. Owing to the novelty of reasoning and sound conclusions derived on solid scientific foundations, it is expected that this work will produce such results that can be truly useful for policy makers at national and international levels.

Real estate and stocks are two major asset types in an investor’s portfolio. Therefore, this paper aims to investigate the relationship between these two markets to provide a valuable insight into the process of portfolio optimization and security selection.

This study examines the long-run relationship between residential real estate prices and stock market index in the case of Germany for the period of 2005-2017 by applying time series econometrics techniques. To this aim, this study uses Hedonic House Price Index as a proxy for real estate prices and DAX30 as a proxy for stock prices. Moreover, three additional variables, namely, consumer confidence, credit availability and supply of mortgage loans, are incorporated as control variables to assess the robustness of the results.

Obtained empirical results indicate a long-run relationship between stock prices and real estate prices which suggests that in long-run, there is no diversification benefit from allocating stock and real estate assets in a portfolio. This finding is especially important for long-term investors such as pension funds.

To the authors’ best knowledge, this is the first study that empirically investigates the relationship between the real estate market and stock prices using the Hedonic Price Index for the case of Germany.

Consumer-generated online product reviews (OPRs) have become a crucial source of information for consumers; however, OPRs are increasingly being incentivized. The purpose of this paper is to find a method of sponsorship and disclosure that could be considered ethically sound.

This study adopted a quasi-experimental approach to clarifying how the method of sponsorship impacts reader perceptions of OPRs in terms of helpfulness, credibility and purchase intention. Two experiments were performed on an online platform using data from 480 participants. Hypotheses were tested using analysis of covariance.

Meaning under the premise that sponsorship information is disclosed and not withheld from the readers, Study 1 revealed that experiential sponsorship is the best sponsorship. Study 2 revealed that featuring reviewers with greater influence in the online community increases the positive influence of disclosing experiential sponsorship on OPR persuasiveness.

The findings in this study provide rational incentives for firms to disclose sponsorship information, i.e. demonstrate high ethical standards in marketing. This was shown to create a win-win-win situation for consumers, firms and reviewers. Managerial implications for online marketing managers are also discussed.

Most decision-making problems in construction are complex and difficult to solve, as they involve multiple criteria and multiple decision makers in addition to subjective uncertainties, imprecisions and vagueness surrounding the decision-making process. In many instances, the decision-making process is based on linguistic terms rather than numerical values. Hence, structured fuzzy consensus-reaching processes and fuzzy aggregation methods are instrumental in multi-criteria group decision-making (MCGDM) problems for capturing the point of view of a group of experts. This chapter outlines different fuzzy consensus-reaching processes and fuzzy aggregation methods. It presents the background of the basic theory and formulation of these processes and methods, as well as numerical examples that illustrate their theory and formulation. Application areas of fuzzy consensus reaching and fuzzy aggregation in the construction domain are identified, and an overview of previously developed frameworks for fuzzy consensus reaching and fuzzy aggregation is provided. Finally, areas for future work are presented that highlight emerging trends and the imminent needs of fuzzy consensus reaching and fuzzy aggregation in the construction domain.
