The change of planned happenstance skills and its association with career-related variables during school-to-work transition

The current study examined how planned happenstance skills (i.e., curiosity, flexibility, persistence, optimism, and risk-taking) changed during school-to-work transition and how career-related variables were associated with the initial levels and change rates of planned happenstance skills. In a sample of 307 South Korean college students, all planned happenstance skills except for risk-taking decreased over time. Furthermore, some of the career-related variables were associated with the initial level and the change rates of planned happenstance skills. In sum, the current study suggests that utilizing planned happenstance skills may be a worthwhile pursuit during school-to-work transition.     

Becoming an academic: the role of doctoral capital in the field of education

This paper draws on Bourdieu’s concepts of field, capital and habitus to examine the learning and enculturation of alumni of a Canadian PhD programme in the discipline of Education. We introduce the concept of doctoral capital to help explain how and why some PhD graduates go on to secure faculty positions and others do not. Our research suggests that certain existing and acquired academic practices, attributes, dispositions and behaviours collectively form a type of doctoral capital that alumni can then use in the academic marketplace.     

Grounded blends and mathematical gesture spaces: developing mathematical understandings via gestures

This paper examines how a person’s gesture space can become endowed with mathematical meaning associated with mathematical spaces and how the resulting mathematical gesture space can be used to communicate and interpret mathematical features of gestures. We use the theory of grounded blends to analyse a case study of two teachers who used gestures to construct a graphical anti-derivative while working on a professional development task in a calculus modelling activity. Results indicate that mathematical gesture spaces can encourage mathematical experimentation, lighten the cognitive load for students and can be limited by a person’s physical constraints.     

Theory development and convergence of human resource fields: Implications for human performance technology

This study examines major theory developments in human resource (HR) fields and discusses implications for human performance technology (HPT). Differentiated HR fields are converging to improve organizational performance through knowledge‐based innovations. Ruona and Gibson (2004) made a similar observation and analyzed the historical evolution and convergence of three HR‐related fields: human resource management (HRM), human resource development (HRD), and organization development (OD). A field left out in their analysis is HPT. Many learning professionals recognize HPT as a more comprehensive approach to improving organizational performance issues (Molenda & Pershing, 2008; Pershing, 2006). However, little research has been done to advance the theory development of HPT and discuss its relationships within HR fields. This study adds a new perspective to that of Ruona and Gibson's historical analysis of HR fields by examining convergence issues from a theory development perspective.     

Effects of forefoot bending stiffness of badminton shoes on agility,comfort perception and lower leg kinematics during typical badminton movements

This study investigated whether an increase in the forefoot bending stiffness of a badminton shoe would positively affect agility, comfort and biomechanical variables during badminton-specific movements. Three shoe conditions with identical shoe upper and sole designs with different bending stiffness (Flexible, Regular and Stiff) were used. Elite male badminton players completed an agility test on a standard badminton court involving consecutive lunges in six directions, a comfort test performed by a pair of participants conducting a game-like practice trial and a biomechanics test involving a random assignment of consecutive right forward lunges. No significant differences were found in agility time and biomechanical variables among the three shoes. The players wearing the shoe with a flexible forefoot outsole demonstrated a decreased perception of comfort in the forefoot cushion compared to regular and stiffer conditions during the comfort test (p < 0.05). The results suggested that the modification of forefoot bending stiffness would influence individual perception of comfort but would not influence performance and lower extremity kinematics during the tested badminton-specific tasks. It was concluded that an optimisation of forefoot structure and materials in badminton shoes should consider the individual’s perception to maximise footwear comfort in performance.     

Malayanized Chinese-language cinema: on Yi Shui’s Lion City,Black Gold,and film writings

This article discusses how the Singaporean Chinese director, Yi Shui, created a Malayanized Chinese-language cinema during the 1950s and 1960s, and offers a retrospective of the way people in Malaya and Singapore framed their nation-building discourse in terms of anti-colonialism and anti-imperialism after the Bandung Conference in 1955. This article holds that the term huayu dianying (Chinese-language cinema) was not first used in the 1990s by scholars in Hong Kong and Taiwan, but that its origins can be traced to Singapore and Malaya in the 1950s where Yi Shui promoted Malayanized Chinese-language cinema in the Nanyang Siang Pau. This earlier use of the term “Chinese-language cinema” overlaps with its current academic usage, including films in Mandarin and Chinese dialects. In 1959, Yi Shui’s essays were collected in On Issues of the Malayanization of Chinese-Language Cinema. Yi Shui also directed several Malayanized Chinese-language films. This article analyzes his “Chinese language cinema” film practice by examining the discourses surrounding the “Malayanization of Chinese-language cinema” in order to show that his semi-documentary Lion City and the melodrama Black Gold attempted to mediate the misunderstandings rooted in the national boundaries and politics of various dialect groups through a “multi-lingual symbiosis” of Chinese languages.     

Age Differences in Online Social Networking: Extending Socioemotional Selectivity Theory to Social Network Sites

This article extends socioemotional selectivity theory to online social networking by examining age differences in the size and composition of Facebook networks across a wide age range of Facebook users (18 to 93 years old) in a nationally representative sample. Findings suggest increasing selectivity of Facebook social partners with age. Compared to younger adults, friend networks of older adults are smaller but contain a greater proportion of individuals who are considered to be actual friends. Moreover, a higher proportion of actual to total Facebook friends is associated with lower levels of social isolation and loneliness across the life span.     

Introduction of Molecular Methods into a Food Microbiology Curriculum

Maintaining current, relevant curriculum in undergraduate Food Microbiology courses is essential for training future experts in food quality and safety. Having an understanding of the fundamental techniques (for example, polymerase chain reaction [PCR]) that are used in the food industry and regulatory agencies is critical for students entering the workforce. The purpose of this study was to assess the efficacy of integrating molecular methods into an undergraduate Food Microbiology course in both lecture and laboratory settings. Modules on PCR and pulsed‐field gel electrophoresis (PFGE), both of which are currently used by government agencies and the food industry to investigate the presence and persistence of foodborne pathogens, were developed, introduced, and evaluated among 269 students over 4 y. Multiple teaching and learning styles were incorporated through (i) traditional lecture format on the basics of PCR and PFGE; (ii) hands‐on group activities to build upon the lecture instruction; (iii) performing PCR and PFGE in the laboratory; and (iv) group discussions to analyze results from laboratory exercises. Pre‐ and postinstruction evaluations revealed significant increases in understanding and application of both methods in lecture and laboratory settings as demonstrated by 0.60 and 0.51 mean normalized gains for respective PCR and PFGE lectures and 0.50 and 0.56 mean normalized gains in respective labs. Academic year significantly impacted score improvement, potentially due to hidden factors, such as previous exposure to material and student aptitude. This study provides the platform for successful introduction of molecular techniques in an undergraduate Food Microbiology course. The guidelines and materials developed by our group are publicly available for use by other institutions.     

Traceable clonal culture and chemodrug assay of heterogeneous prostate carcinoma PC3 cells in microfluidic single cell array chips

Cancer heterogeneity has received considerable attention for its role in tumor initiation and progression, and its implication for diagnostics and therapeutics in the clinic. To facilitate a cellular heterogeneity study in a low cost and highly efficient manner, we present a microfluidic platform that allows traceable clonal culture and characterization. The platform captures single cells into a microwell array and cultures them for clonal expansion, subsequently allowing on-chip characterization of clonal phenotype and response against drug treatments. Using a heterogeneous prostate cancer model, the PC3 cell line, we verified our prototype, identifying three different sub-phenotypes and correlating their clonal drug responsiveness to cell phenotype.     

Experimental intervention research on students with specific poor comprehension: a systematic review of treatment outcomes

Students with specific poor comprehension (SPC) can sound out words accurately, but have difficulty understanding what they read. However, most existing reading intervention studies on students with reading disabilities did not differentiate students with SPC from other types of students with reading disabilities who accompany with decoding difficulties. The purpose of this systematic review was to synthesize findings from 14 experimental intervention studies that have included students with SPC with the goal of increasing reading comprehension. Out of eight types of interventions identified, Reciprocal Teaching (g = .856) demonstrated the largest effect size. Metalinguistic intervention showed the effect size of above .50 (a medium effect size), suggesting that intervention that explicitly teaches high-level oral language strategies was positive to improve reading performances of students with SPC. Findings also suggest a need to specify the classification criteria of students with SPC to broaden an understanding about the evidence-based intervention for students with SPC. Practical implications for effective practice, limitations, and future directions are discussed.
