Advantages of Groups in Market Transactions

This paper takes individuals as rationaleconomic decision makers but ones operating withinwell-defined groups not just today but into the futurewhen a reputation for fair dealing will be ofsignificance. The paper explores the functional advantageswhich might accrue from group membership in suchcircumstances. As social science makes clear, mostgroups come into being for social and cultural reasonsindependent of any obvious immediate economic advantage.For this reason, this paper is exploratory of theboundary between economic reasoning and that of othersocial sciences. It explores the bridge toofar, cited by Loveridge in the 1993 special editionof this journal. This is a metaphor for the possibilityof a meaningful connector between social psychologicaland economic reasoning. This paper tentatively looks into the relationships that might beestablished between the specific economic analysiscovered by this paper and that deployed in other socialsciences. In essence, the paper suggests that bothreputational and informational benefits arise from groupbehavior. These benefits accrue to both its members andothers. By extension it is argued that similaradvantages can accrue to families ofproducts in marketing. In both cases, reputationallinkage serves as a commitment device(Schelling, 1960) with ensuing benefits to all membersof the group or product family. These relationships areseen to mediate the reputational guarantees given to consumers.     

Quantile forecasts for financial volatilities based on parametric and asymmetric models

For financial volatilities such as realized volatility and volatility index, a new parametric quantile forecast strategy is proposed, focusing on forecast interval and value at risk (VaR) forecast. This fully addresses asymmetries in 3 parts: mean, volatility and distribution. The asymmetries are addressed by the LHAR (leverage heterogeneous autoregressive) model of McAleer and Medeiros (2008) and Corsi and Reno (2009) for the mean part, by the EGARCH model for the volatility part, and by the skew-t distribution for the error distribution part. The method is applied to the realized volatilities and the volatility indexes of the US S&P 500 index, the US NASDAQ index, the Korea KOSPI index in which significant asymmetries are identified. Considerable out-of-sample forecast improvements of the forecast interval and VaR forecast are demonstrated for the volatilities: forecast intervals of volatilities have better coverages with shorter lengths and VaR forecasts of volatility indexes have better violations if asymmetries are properly addressed rather than ignored. The proposed parametric method reveals considerably better out-of-sample performance than the recently proposed semiparametric quantile regression approach of Zikes and Barunik (2016).     

Race–Ethnicity and Culture in the Family and Youth Outcomes: Test of a Path Model with Korean American Youth and Parents

This study examined the interplay of parental racial–ethnic socialization and youth multidimensional cultural orientations to investigate how they indirectly and directly influence youth depressive symptoms and antisocial behaviors. Using data from the Korean American Families Project (220 youths, 272 mothers, and 164 fathers, N = 656), this study tested the relationships concurrently, longitudinally, and accounting for earlier youth outcomes. The main findings include that racial–ethnic socialization is significantly associated with mainstream and ethnic cultural orientation among youth, which in turn influences depressive symptoms (but not antisocial behaviors). More specifically, parental racial–ethnic identity and pride discourage youth mainstream orientation, whereas cultural socialization in the family, as perceived by youth, increases ethnic orientation. These findings suggest a varying impact of racial–ethnic socialization on the multidimensional cultural orientations of youth. Korean language proficiency of youth was most notably predictive of a decrease in the number of depressive symptoms concurrently, longitudinally, and after controlling for previous levels of depressive symptoms. English language proficiency was also associated with a decrease in depressive symptoms, implying a benefit of bilingualism.     

A dialectic perspective on the interactive relationship between social media and civic participation: the moderating role of social capital

By analyzing representative national survey data, this study explores the ways in which social media and social capital jointly affect civic participation. In particular, the study examines how the use of social media to express opinions or acquire trusted information influence citizens participatory activities in civic affairs. Our findings suggest that both social media use and social capital promote civic activities. Interestingly, this study reveals that social media exert differential effects on civic participation, depending on the individual's level of social capital, rather than having an equal impact on civic participation. The study offers a new perspective from which to examine the relationships between social media, social capital, and civic participation. The results and implications are discussed in detail below.     

Use of the International Prostate Symptom Score (IPSS) in Chinese male patients with benign prostatic hyperplasia

Purpose: To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care.

Methods: A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing test–retest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS).

Results: The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbach’s alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size?=?0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively.

Conclusions: The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups.     

Associations Between Toddlers' Naturalistic Media Experience and Observed Learning from Screens

Using secondary analysis, researchers examined associations between two‐year‐olds' (N = 135) naturalistic use of interactive and noninteractive media with performance on a screen‐based learning task. Parents reported the number of minutes that children spent the previous day doing nine media‐related activities (e.g., watching television, playing handheld videogames). The object‐retrieval task required children to watch a hiding event on video and then search for the object on another screen or a real felt board. Results indicated that toddlers' naturalistic experience with interactive (but not noninteractive) media predicted their screen‐based learning in the laboratory. This was true regardless of whether children were tested using interactive or noninteractive video, suggesting that using interactive media (but not watching noninteractive video) is associated with children's learning from screen media generally.     

Study of musculoskeletal risks of the office-based surgeries

Due to the cost and time benefits associated with patients and physicians, outpatient surgeries continue to become more and more popular over time. With the increase in the number of office-based surgical procedures, the prevalence of work-related musculoskeletal disorders (WMSDs) associated with office-based surgeries has been reported. The purpose of this pilot study is to ergonomically evaluate the risk of work-related musculoskeletal disorders of physicians/surgeons performing office-based surgery (OBS). Ergonomic assessment tools included Questionnaire, the BodyMap and the Rapid Upper Limb Assessment for measuring potential ergonomic concerns. The findings have shown that the ergonomic issues of greatest concerns were the discomforts in the neck, shoulders, arms/wrists, and back. Some additional comments were provided by the participants regarding the duration of discomfort or clarification on the frequency of their body discomfort. This study suggests that there is a considerable risk of musculoskeletal injuries of physicians/surgeons performing the OBS tasks. By properly using the ergonomic assessment techniques, valuable information on ergonomic OBS workplace design and selection could assist in the early interventions of WMSD prevention.     

Review of research on victims' experiences in restorative justice: Implications for youth justice

Despite claims that restorative justice is “victim centered,” and deliberately focused on healing harms to victims, some studies report that particular applications of restorative justice may not be fully consistent with its fundamental principles and values. Under such circumstances these programs may focus on outcomes (e.g., rehabilitation of youthful offenders) rather than process, and in doing so, may fail to identify and respond effectively to victims' needs. To take a closer look at this phenomenon, this article examines a sample of published restorative justice studies that highlight ‘negative’ experiences of victims. Given a number of studies that indicate victims typically have satisfying experiences in restorative justice practices such reports of negative experiences and practices should be viewed as ‘outliers.’ However, such outliers may provide substantively meaningful insights that inform best practice standard for restorative justice. Implications are drawn for the use of restorative justice practices for youth justice.     

Mandated RFID and Institutional Responses: Cases of Decentralized Business Units

Using a theory‐building approach based on case studies, this research explores the responses of four decentralized business units to institutional pressure to adopt Radiofrequency Identification (RFID) technology. The institutional pressure emanates from the Department of Defense, and the affected decentralized business units operate in a large defense contractor. Institutional theory explains how organizations respond to external pressures to adopt new procedures, policies, and technologies. The case studies show how business units vary in their response to the RFID mandate and how different internal dynamics manifest. The responses range from complying faithfully, primarily concerned with satisfying the external constituent, to completely ignoring the mandate and focusing on internal efficiency initiative utilizing RFID. A number of propositions are developed to better understand the organizational responses to exogenous pressure to implement RFID. The paper concludes by proposing future research directions and issues that must be considered further.
