Development and Validation of the Single Item Narcissism Scale (SINS)
Main Objectives: The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies).
Methods: In 11 independent studies (total N = 2,250), we demonstrate the SINS\u27 psychometric properties.
Results: The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism.
Significance: The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures
Development and Validation of the Single Item Trait Empathy Scale (SITES)
Empathy involves feeling compassion for others and imagining how they feel. In this article, we develop and validate the Single Item Trait Empathy Scale (SITES), which contains only one item that takes seconds to complete. In seven studies (N = 5724), the SITES was found to be both reliable and valid. It correlated in expected ways with a wide variety of intrapersonal outcomes. For example, it is negatively correlated with narcissism, depression, anxiety, and alexithymia. In contrast, it is positively correlated with other measures of empathy, self-esteem, subjective well-being, and agreeableness. The SITES also correlates with a wide variety of interpersonal outcomes, especially compassion for others and helping others. The SITES is recommended in situations when time or question quantity is constrained
Learner-generated digital media (LGDM) as an assessment tool in tertiary science education: A review of literature
© 2018, The International Academic Forum (IAFOR). All rights reserved. Learner-Generated Digital Media (LGDM) in tertiary science education focuses on research skills, inquiry, active learning, teamwork, and collaboration. LGDM across disciplines is under-theorised, under-researched, and only in its early development. This paper evaluates the research in the field of LGDM in tertiary science education. The literature review had four stages – identification, screening, filtering, and selection of relevant scholarly research. Results showed that research in the field of LGDM assignments had been done without a systematic approach to designing, implementing, and evaluating the assessment task. Most studies neglected student digital media training and are characterised by a lack of compelling marking rubrics or strategies to ensure efficient groupwork. Studies also lack rigorous methodologies for data capture to evaluate the intervention and they use small sample size cohorts and different digital media types that require different sets of production skills. With the empirical data available, validation of the benefits of LGDM assignments in science education is not possible, and studies have limited scalability. These gaps in the literature create a need to develop theoretical models for the design, implementation, and evaluation of LGDM in the classroom. This paper discusses future research needs in this field and the implications for assessment design
A Behavioral Confirmation and Reduction of the Natural versus Synthetic Drug Bias
Research reveals a biased preference for natural versus synthetic drugs; however, this research is based upon self-report and has not examined ways to reduce the bias. We examined these issues in five studies involving 1,125 participants. In a Pilot Study (N = 110), participants rated the term natural to be more positive than the term synthetic, which reveals a default natural-is-better belief. In Studies 1 (N = 109) and 2 (N = 100), after a supposed personality study, participants were offered a thank you “gift” of a natural or synthetic pain reliever. Approximately 86% (Study 1) and 93% (Study 2) of participants chose the natural versus synthetic pain reliever, which provide a behavioral choice confirmation of the natural drug bias. In Studies 3 (N = 350) and 4 (N = 356), participants were randomly assigned to a control or experimental condition and were asked to consider a scenario in which they had a medical issue requiring a natural versus synthetic drug. The experimental condition included a stronger (Study 3) or weaker (Study 4) rational appeal about the natural drug bias and a statement suggesting that natural and synthetic drugs can be good or bad depending upon the context. In both studies, the natural bias was reduced in the experimental condition, and perceived safety and effectiveness mediated this effect. Overall, these data indicate a bias for natural over synthetic drugs in preferences and behavioral choices, which might be reduced with a rational appeal
Structure and thermodynamics of platelet dispersions
Various properties of fluids consisting of platelike particles differ from
the corresponding ones of fluids consisting of spherical particles because
interactions between platelets depend on their mutual orientations. One of the
main issues in this topic is to understand how structural properties of such
fluids depend on factors such as the shape of the platelets, the size
polydispersity, the orientational order, and the platelet number density. A
statistical mechanics approach to the problem is natural and in the last few
years there has been a lot of work on the study of properties of platelet
fluids. In this contribution some recent theoretical developments in the field
are discussed and experimental investigations are described.Comment: 23 pages, 18 figure
The Internet explosion, digital media principles and implications to communicate effectively in the digital space
© 2018, © The Author(s) 2018. Being literate has traditionally meant being able to read and write using the media of the day. In the 21st century, being literate requires additional skills such as competence with digital media creation. Until recently, those who could afford and use equipment and applications to produce digital media content were typically developers and technicians. With the development of prosumer electronics, in conjunction with the use of mobile devices and tablets, a shift has occurred in the accessibility of these tools, becoming more affordable for the general population. Video sharing services, social software and Web 2.0 applications have made it possible to host a digital media ecosystem on the Internet, and this has led to the proliferation of User-Generated Content. These technological advances have changed how we communicate, socialise and learn. Effective communication using digital media is underpinned by a set of design principles which most students are not likely to be aware. This paper built on two previous papers on the Digital Media Literacy Framework and the Taxonomy of Digital Media types for teaching and learning. It argues the importance of digital media principles to develop effective communication in the digital space. Students now require knowledge of these principles, in conjunction with conceptual and functional skills, for effective communication in the digital space
A Systematic Approach to Designing, Implementing, and Evaluating Learner-Generated Digital Media (LGDM) Assignments and Its Effect on Self-regulation in Tertiary Science Education
© 2019, Springer Nature B.V. This study explored the self-regulation strategies and learning experiences of undergraduate science students completing Learner-Generated Digital Media (LGDM) assignments that had been implemented using a theory-driven, systematic approach. The rationale for using LGDM in science education is to facilitate student learning of complex scientific concepts through the multimodal representation of content using digital media. The study was conducted in seven science subjects from first to third year in Autumn 2017, using a sample of 348 undergraduate science students attending a university located in Sydney, Australia. All the participants were enrolled in subjects that required them to communicate complex scientific concepts using digital media. Training on LGDM was conducted online (n = 199) and in blended mode (n = 149). The study used a mixed-methods approach with a validated self-regulation questionnaire, LMS logs, assessment scores, group contribution data, open-ended questions, and interviews. Online students were more likely than blended students to report using self-regulation strategies for goal setting, time management, task strategies, and help-seeking. Data triangulation revealed that participation in LGDM assignments was perceived by students to contribute to their science content knowledge, provide them with digital media skills, and nurture their capacity for working in groups. The findings of this study have implications for how LGDM is deployed in science education
Using factor analysis to validate a questionnaire to explore self-regulation in learner-generated digital media (LGDM) assignments in science education
© 2019 Australasian Society for Computers in Learning in Tertiary Education (ASCILITE). This research is a validation study of a survey instrument to assess student self-regulation which aims to fill a methodological gap by capturing self-regulation processes while completing learner-generated digital media (LGDM) assignments. For this purpose, the study developed and validated a self-regulation learning questionnaire. Data were gathered from seven science subjects (Years 1 to 3, n = 341) which used LGDM assignments during Semester 1, 2017. Students were asked to complete a 40-item online questionnaire. The questionnaire was administered at three times during the semester (Weeks 2, 6, and 10). Exploratory factor analysis was used to identify factor structures, followed by confirmatory factor analysis to test the validity of the constructs defined by exploratory factor analysis. Analysis of the data revealed a ten-factor structure - six concerning self-regulation, two concerning student attitudes towards LGDM assignments, one concerning assignment ownership, and one concerning assignment motivation. The variables empirically verified in this study have important practical implications, as they could provide educators with the direction in which to target interventions to improve learners' experiences with LDGM. The study findings also contribute to the field by providing scholars with a validated research instrument that can be used in future studies
Silicon dendritic web material
The development of a low cost and reliable contact system for solar cells and the fabrication of several solar cell modules using ultrasonic bonding for the interconnection of cells and ethylene vinyl acetate as the potting material for module encapsulation are examined. The cells in the modules were made from dendritic web silicon. To reduce cost, the electroplated layer of silver was replaced with an electroplated layer of copper. The modules that were fabricated used the evaporated Ti, Pd, Ag and electroplated Cu (TiPdAg/Cu) system. Adherence of Ni to Si is improved if a nickel silicide can be formed by heat treatment. The effectiveness of Ni as a diffusion barrier to Cu and the ease with which nickel silicide is formed is discussed. The fabrication of three modules using dendritic web silicon and employing ultrasonic bonding for interconnecting calls and ethylene vinyl acetate as the potting material is examined
