The development in Video on Demand (VOD) services technology has proven to increase the chance of binge-watching. However, early literature about binge-watching only focuses on health risk and their opinion on this topic. Therefore, this study intended to find aspects that affect binge-watching duration among college students. Theory of planned behaviour (TPB) that discusses the role of attitude and intention on an individual’s behavior was applied to find the affected aspect of binge-watching duration. Variables such as need for completion, personalised suggestions, and cliffhanger were analysed as moderators. Participants of this study were active Indonesian undergraduate students who were selected by applying snowball sampling method. Data were collected using online questionnaire using Likert Scale and terbuka questions on Google Form. The results indicate that TPB, need for completion, personalised suggestions, and cliffhanger correlated to binge-watching duration among undergraduate students.

Stroke Knowledge

The purpose of the study was to develop and test the psychometric properties of a stroke knowledge assessment tool based on a mixed-methods approach and a synthesis of the relevant literature on stroke. The content of the tool was predominantly developed by the findings from a qualitative study involving ten stroke patients who had been admitted to a state hospital due to a stroke during the previous 2 years.  The other source for tool construction was the information that emerged from an extensive literature review. The resulting online questionnaire was divided into three main sections namely i) demographics ii) stroke knowledge and iii) stroke response. A 5-point Likert scale was chosen to answer each question in Sections B and C, which facilitates the analysis process using descriptive and inference statistics. The tool was subjected to psychometric testing with promising results. The use of a standard tool, such as SKAT, which is the one presented in this paper, presents health professionals, who are in a prime position to gauge healthcare educational needs, with the means to assess stroke knowledge and carry out interesting uniform comparisons between different geographical and ethnical populations. The targeted audience for the use of this tool is a). The general population and/or b). A population where stroke knowledge enhancement is being planned. SKAT can then inform educational and awareness needs.

Using data from an enumerated network of worldwide flight connections between airports, we examine how sampling designs and sample size influence network metrics. Specifically, we apply three types of sampling designs: simple random sampling, nonrandom strategic sampling (i.e., selection of the largest airports), and a variation of snowball sampling. For the latter sampling method, we design what we refer to as a controlled snowball sampling design, which selects nodes in a manner analogous to a respondent-driven sampling design. For each design, we evaluate five commonly used measures of network structure and examine the percentage of total air traffic accounted for by each design. The empirical application shows that (1) the random and controlled snowball sampling designs give rise to more efficient estimates of the true underlying structure, and (2) the strategic sampling method can account for a greater proportion of the total number of passenger movements occurring in the network.

Purpose This paper revisits the concept of compatibility between old and new architecture to clarify its meaning. Design/methodology/approach Document analysis is employed to critically review relevant literature, including Charters and UNESCO Recommendations. Findings Visual and/or tangible indicators such as forms and materials are often suggested in the literature to determine compatibility and to inform decision makers whether new architectural projects should reproduce, or reinterpret, or rather contrast with, historic buildings in situ. As a consequence, compatible design becomes confined to a visual, object-based, worldview. Yet, architecture transcends the sense of vision. Research limitations/implications Examples of architectural projects are given to explain each design option, but are not thoroughly described. Still, this paper provides a useful reference for future dialogue and research that aim at reducing the conservation vs development struggle in historic places, whether urban areas or entire cities, such as World Heritage Cities. Practical implications The lessons learned may stimulate reflection on the effectiveness of design criteria and other tools in guiding decision makers in their search for, and assessment of, compatibility. Originality/value This paper reveals that compatibility is an evolving concept, associated with human, man-made and natural indicators. Design options are not simply aesthetic categories. The author proposes that the selection of a design option for new architecture should follow the process that guides the selection of a conservation treatment for old architecture.

Abstract Background Orthorexia Nervosa (ON) is defined as a pathological preoccupation characterized by obsessive beliefs and compulsive behaviors regarding 'pure' eating behaviors. Many scales have been established and display good results regarding reliability and validity measures, including but not limited to ORTO-R (revised version of ORTO-15), Eating Habits Questionnaire, Teruel Orthorexia Scale (TOS) and the Düsseldorf Orthorexia Scale (DOS). Among these, the DOS seems to be a promising measure for multiple reasons. The current paper aims to validate the DOS, a measure of ON, in a non-Western population of Lebanese adolescents. Methods This was a cross-sectional designed study, conducted between May and June 2020, which enrolled 555 adolescents (15–18 years old; 75.7% females). Due the coronavirus pandemic outbreak, the data were gathered through snowball sampling using an online questionnaire. The DOS, TOS and ORTO-R scales were used in this study to screen for orthorexic tendencies and behaviors. Results We tested four competing structural models of the DOS assessing its factorial validity. The results of the current investigation revealed that the one-factorial model is the best one to represent the structure of the questionnaire. We provided evidence for validity for the DOS through demonstrating that it correlates significantly with other measures of orthorexic behaviours (Teruel Orthorexia Scale and ORTO-R). Finally, we have gathered evidence that the orthorexic behaviours as measured by DOS are not associated with age (r = −.02; p = .589), household crowding index (r = .02; p = .578), and Body Mass Index (r = .04; p = .297). Yet, females as compared to males achieved higher scores (M = 20.07, SD = 6.38 vs M = 18.29, SD = 6.37; p = .005; d = .28). Conclusion The Arabic version of the DOS seems to be a structurally valid and internally consistent questionnaire measuring orthorexic eating behavior in a sample of Lebanese adolescents. This tool may be useful for psychologists, psychiatrists, dietitians and other clinicians in the assessment and the treatment of the multidimensional nature of ON.
