Why Do We Indulge? Exploring Motivations for Binge Watching

This study explored an expanded definition and motivations for binge-watching behavior. In addition to the number of episodes, the amount of time, frequency, and engagement in binge-watched programs were considered for the binge-watching definition. Study findings revealed that over half of the respondents of this study were light binge viewers. In addition, among a total of seven motivations identified in literature, only the entertainment motivation is a significant predictor of binge watching for those with a low level of binge watching, while both passing time and entertainment were found to be significant predictors for those with a high level of binge watching.     

The development of search filters for adverse effects of surgical interventions in medline and Embase

Background

Search filter development for adverse effects has tended to focus on retrieving studies of drug interventions. However, a different approach is required for surgical interventions.

Objective

To develop and validate search filters for medline and Embase for the adverse effects of surgical interventions.

Methods

Systematic reviews of surgical interventions where the primary focus was to evaluate adverse effect(s) were sought. The included studies within these reviews were divided randomly into a development set, evaluation set and validation set. Using word frequency analysis we constructed a sensitivity maximising search strategy and this was tested in the evaluation and validation set.

Results

Three hundred and fifty eight papers were included from 19 surgical intervention reviews. Three hundred and fifty two papers were available on medline and 348 were available on Embase. Generic adverse effects search strategies in medline and Embase could achieve approximately 90% relative recall. Recall could be further improved with the addition of specific adverse effects terms to the search strategies.

Conclusion

We have derived and validated a novel search filter that has reasonable performance for identifying adverse effects of surgical interventions in medline and Embase. However, we appreciate the limitations of our methods, and recommend further research on larger sample sizes and prospective systematic reviews.     

Technological opportunity discovery for technological convergence based on the prediction of technology knowledge flow in a citation network

As technological convergence has recently become a mainstream innovation trend, technological opportunities need to be explored in heterogeneous technology fields. Most of the previous convergence studies have taken a retrospective view in measuring the degree of convergence and monitoring the converging trends. This paper proposes a quantitative future-oriented approach to technological opportunity discovery for convergence using patent information. In a future-oriented approach, technological opportunities for convergence are suggested by predicting potential technological knowledge flows (TKFs) between heterogeneous fields. The potential TKFs are predicted by a link prediction method in a directed network, which is suggested in this paper to represent the direction of the predicted TKFs by adapting the concept of bibliographic coupling and edge-betweenness centrality. Converging technological opportunities are proposed as incremental and radical technological opportunities by extracting the potential increased knowledge flow links and emerging knowledge flow links. Moreover, the direction and themes of the predicted potential TKFs are provided as technological opportunities for convergence. As an illustration of the proposed method, the technological opportunities between biotechnology (BT) and information technology (IT) are explored. Firms and researchers can use the proposed method to seek out new technological opportunities from various technologies so that R&D policymakers can plan new R&D projects on technological convergence.     

The cementation of coarse dust to indoor surfaces

Dust accumulation is an important management and conservation problem in historic houses. Laboratory and field observations show that high relative humidity enhances the cementation of particles to underlying surfaces. The hygroscopic nature of particles or the fibres to which they adhere influences this cementation process. The cements, which can form in a matter of hours at high humidity, appear to be microcrystalline calcites. Reducing the impact of this process on heritage objects requires preventing dust deposits, especially in periods of high humidity.     

Are model PISA pupils happy at school? Quality of school life of adolescents in Finland and Korea

This paper explores the quality of school life (QSL) of two ‘model pupils’ in Programme for International Student Assessment (PISA) tests, Finland and Korea, and investigates students’ views on the central aspects of QSL (general satisfaction, peer relations and teacher–student relations) using PISA 2012 data. It also seeks to interpret how specific institutional and sociocultural aspects are linked to QSL. The analyses show that Finnish and Korean adolescents’ views on QSL are less positive compared with the OECD average; Finnish adolescents’ views on QSL are more positive than those of Korean adolescents regarding general satisfaction and peer relations but are not clearly related to teacher–student relations. Since Finnish and Korean adolescents’ views on QSL partly differ from those of their Nordic and East Asian counterparts, the distinct Nordic or East Asian image of QSL could not be revealed in the study. This article proposes that QSL demands more attention in the era of ‘rankings and benchmarked educational models’, with consideration to the universality and uniqueness of institutional, sociocultural and historical factors of one’s own and others’ schooling.     

Beyond the learning process and toward the knowledge creation process: Linking learning and knowledge in the supportive learning culture

This integrative literature review synthesizes the concepts and process of organizational knowledge creation with theories of individual learning. The knowledge conversion concept (Nonaka & Takeuchi, 1995; Nonaka, Toyama, & Byosière, 2001) is used as the basis of the organizational knowledge creation process, while major learning theories relevant to working adult learners are newly synthesized into four types of individual learning processes: adaptive, generative, transformative, and reflective. The results suggest an integrative conceptual flow map of individual and organizational learning facilitated by culture and management system enablers. Implications for using this conceptual framework for practicing performance technology solutions are also discussed.     

Relationships between cognitive diagnosis, CTT, and IRT indices: an empirical investigation

Cognitive diagnosis models (CDMs) continue to generate interest among researchers and practitioners because they can provide diagnostic information relevant to classroom instruction and student learning. However, its modeling component has outpaced its complementary component??test construction. Thus, most applications of cognitive diagnosis modeling involve retrofitting of CDMs to assessments constructed using classical test theory (CTT) or item response theory (IRT). This study explores the relationship between item statistics used in the CTT, IRT, and CDM frameworks using such an assessment, specifically a large-scale mathematics assessment. Furthermore, by highlighting differences between tests with varying levels of diagnosticity using a measure of item discrimination from a CDM approach, this study empirically uncovers some important CTT and IRT item characteristics. These results can be used to formulate practical guidelines in using IRT- or CTT-constructed assessments for cognitive diagnosis purposes.     

Family Processes and Psychosocial Problems of the Young Korean Gifted

It is widely known that Korean parents have a high aspiration for providing opportunities of higher education and high expectations for their children’s academic achievement. Young Korean gifted children with ages from four to ten years did not show many psychosocial problems. However, some showed such problems as distractibility and inattentiveness, aggressiveness, helplessness, or psychiatric symptoms, when parents exert pressure, fathers are not involved in education, or parents do not discipline children’s behavior. Korean young gifted children showed high motivation for learning, when parents provide support, help, and supervision on TV watching. Based on the results, it was suggested that parents provide support for learning, rather than pressure on learning, and discipline their children’s behavior when they are young. In addition, fathers need to be more involved in their children’s learning in order to prevent psychosocial problems of the young gifted.     

Haunted Trauma Narratives of Inclusion,Race, and Disability in a School Community

By typical definitions in the special education world, inclusion would not be recognizable as it exists at Memorial Elementary. Memorial is responding to a widely documented trend in public schools: over-representation of students of color, particularly Black and Brown students, in high-incidence special education categories, including emotional and behavioral disabilities (EBD). I conceptualize EBD as unacknowledged suppression of hauntings from transgenerational trauma—legacies of institutional racism, poverty, and attempts at dehumanization. My primary hypothesis is that Memorial’s practice and ethic of unconditional belonging has been a transformation afforded by being haunted. I argue that haunted trauma narratives affirm and reconstruct the personhood of students of color with ghosts of trauma. Through narrativizing, students of color and educators rebuild inclusion from difference-as-allowed toward Martin Luther King Jr.’s (2001) “beloved community” (p. 458). That is, Memorial has redesigned school structures, educators’ beliefs and practices, interactions with children and their families, and other aspects of everyday systems to be organized around the intersections of race, trauma, identity, and community. Though dreaming is undeniably difficult, Memorial also illustrates the transformative power of affective forces from ghosts that demand hope, justice, and healing.
