The Impact of Authority Relations and Feedback Delivery Method on Performance

ABSTRACT

The proliferation of technology has been changing feedback delivery methods in organizations. However, the effectiveness of feedback delivery methods can vary depending on social dynamics (e.g., authority relations) in the organization. The current study was designed to examine the impact of authority relations and feedback delivery methods on performance. A total of 120 participants were recruited to work on a simulated cell-phone assembly task and were exposed to one of the four feedback conditions: (a) authority figure with face-to-face feedback, (b) authority figure with e-mail feedback, (c) non-authority figure with face-to-face feedback, and (d) non-authority figure with e-mail feedback. Results showed that while both feedback delivery methods resulted in high performance with the presence of an authority figure, only face-to-face feedback resulted in high performance with a non-authority figure. Practical considerations for effective feedback delivery methods in relation to authority figures are also discussed.     

Mechanization in building construction projects: assessment and views from the practitioners

Abstract

While mechanization has been widely adopted in the current construction industry, little research has been done to assess the level of mechanization in building construction projects. The aims of this study are to propose a framework that can assess the level of mechanization in building construction projects, to develop a computer-based tool that can help assess mechanization levels, and to collect the views of industry practitioners regarding mechanization. To achieve these goals, a comprehensive literature review was conducted first, and based on which a six-layer assessment framework, namely Mechanization Index for Building Construction Projects, was proposed. After that, Mechanization Index Assessment Tool, a computer-based tool that can assess the level of mechanization in building construction projects, was developed. The developed tool was adopted in 14 construction projects in Singapore. Assessment results showed that the mechanization level of the projects was 48.54 percent out of 100, which is moderate. Results also reported that ‘site preparation’ and ‘underground piping’ were two work types that are more mechanized, while work types of ‘formwork’, ‘tiling’, and ‘painting’ were relatively less mechanized. Additionally, industry practitioners perceived that the mechanization levels in the current building construction projects and industry were moderate and more efforts should be put in this regard, especially from the perspective of the industry. This study is the first piece of research work that assesses the level of mechanization in building construction projects and thus, it contributes to the body of knowledge. Furthermore, the assessment tool developed can easily be used either by industry practitioners or by construction authorities to do mechanization assessment. Thus, this study contributes to the practice as well.     

Subjective Quality of Life Among Individuals who are Homeless: A Review of Current Knowledge

The purpose of this article was to review the current literature on subjective quality of life (SQOL) in individuals who are homeless, with a focus on differences in SQOL (a) between homeless individuals and the general population, (b) based on housing situation, and (c) associated with demographic characteristics (such as age and gender), physical and mental health, and external variables such as service program type. A literature search was conducted of the online databases PubMed and PsycInfo for relevant studies published from January 1981 to August 2011. Although this review showed that individuals who are homeless tended to have lower levels of SQOL compared to the general population or housed individuals, it was also evident that our current understanding of the relationships between SQOL and various demographic, health, and other variables is based on very limited information. More information about the relationships between various characteristics and experiences of individuals who are homeless and SQOL is clearly needed to aid researchers, service providers, and policy-makers in addressing the needs of this population and examining the effectiveness of interventions to end homelessness and improve health among homeless individuals.     

The Estimation of the South Korean Government's Diplomacy for Its Opposing Public North Korea

Based on the influence of the contingency factors of inner organizational and external situational factors, contingency theory of accommodation provides a good explanation for the real public relations practices. A recent series of experimental studies supports the idea that the theory is also applicable in the public's estimation pattern regarding an organization's public relations practices. This survey study is theoretically important when examining and sorting out significant factors in the real population of a notable public diplomacy domain. That is, this research examines how the South Korean people perceive the contingency factors and how people estimate the South Korean government's stance toward its opposing public, North Korea. The regression model of perceived contingency factors and stance estimation was generalizable in the population of this study (R ² = .279). The most influential perceptual predictors in the model include: the North Korean leader's preference for the South Korean president, the relative power of South Korea, the level of commitment of North Korea, the South Korean president's preference for the North Korean leader, the US government's support for the South Korean policy toward North Korea, the South Korean government's certainty to deal with the North Korean military threat, situational difficulties, the South Korean government's knowledge and skill to deal with the threat, the situational duration of threat, and the South Korean president's relation-oriented leadership. Finally, this study discussed practical implications for the government practitioners.     

Trade union support for fathers' use of work–family benefits – lessons from Sweden

Trade unions have traditionally been male-dominated organizations serving men's interests as family breadwinners, primarily through wage-setting. This study explores whether unions will contest the gendered division of parenting to develop values and practices that support men as caregivers. It takes place in Sweden, where unions are strong and fathers have legislated rights to paid parental leave. A mail survey of local unions revealed that the vast majority of unions did not believe it was important to focus attention on men as family caregivers. Only about one-fourth reported activities to improve men's benefit knowledge; only about one-third reported that they helped to implement parental leave at the workplace and only about one-fourth had negotiated contracts that extended leave benefits for fathers. Unions were more active in supporting men as fathers when they prioritized women's equal employment opportunity and when fathers requested union help. Stronger unions were more likely than others to have won enhanced benefits; contracts tended to increase compensation rather than offer more leave time. Swedish unions are in a strong position to promote, help implement and extend work–family benefits for fathers, dissolving the boundary between work and family spheres, but this potential has not yet been realized.     

Cultural Similarities and Differences in Emblematic Gestures

Despite longstanding interest in cultural differences in emblems, there have only been a few systematic investigations of those differences, and to date there is no study that catalogues and compares emblems across different cultural groups to a standard list of verbal messages. This study does so. Encoders from six world regions produced potential emblems from a standard verbal message list. Gestures that were encoded by at least 70% of the encoders in a region were shown to observers from the same regions, and gestures that were judged correctly as the message intended by at least 70% of the decoders in that region were considered emblems. These procedures resulted in the cataloguing of cultural differences in emblems to the same verbal message list. Surprisingly, the results also indicated a small group of emblems that were similarly encoded and decoded across cultures.     

Long-Term Care

This study examines the redistributive effects of public pensions on old-age income inequality, testing whether public pensions function as the “great equalizer.” Unlike the well-known alleviating effect of public pensions on old-age poverty, the effects of public pensions on old-age income inequality more generally have been less examined, particularly outside Western countries. Using repeated cross-sectional data of elderly Koreans between 1998 and 2010, we applied Gini coefficient decomposition to measure the impact of various income sources on old-age inequality, particularly focusing on public pensions. Our findings show that, contrary to expectations, public pension benefits have inequality-intensifying effects on old-age income in Korea, even countervailing the alleviating effects of public assistance. This rather surprising result is due to the specific institutional context of the Korean public pension system and suggests that the “structuring” of welfare policies could be as important as their expansion for the elderly, particularly for developing welfare states.     

Response Agreement Rates Between Child Welfare–Involved Youth and Their Caregivers

ABSTRACT

Data were collected from 40 youth and 37 caregivers, which represented 57 distinct youth and 20 youth–caregiver dyads to measure the level of agreement between youth self-report and their caregivers on a variety of topics. Topics included: the youth's past placements, service use and needs, experiences in the child welfare system, and the youth's emotional problems and social behaviors. Results indicated high agreement between youth and caregiver proxy related to placement history, service use, the restrictiveness of the current environment, and community safety; results indicated low levels of agreement for youth emotional difficulties and prosocial behaviors. Qualitative data were used to further identify some of the differences noted. Overall, the findings support prior research that shows higher agreement within youth–caregiver dyads for objective measures as opposed to subjective and private ones. Implications for future research are discussed, and methodological challenges related to this study are identified.     

Asymptotic variance–covariance matrix of sample autocorrelations for threshold-asymmetric GARCH processes

In the field of financial time series, threshold-asymmetric conditional variance models can be used to explain asymmetric volatilities [C.W. Li and W.K. Li, On a double-threshold autoregressive heteroscedastic time series model, J. Appl. Econometrics 11 (1996), pp. 253–274]. In this paper, we consider a broad class of threshold-asymmetric GARCH processes (TAGARCH, hereafter) including standard ARCH and GARCH models as special cases. Since sample autocorrelation function provides a useful information to identify an appropriate time-series model for the data, we derive asymptotic distributions of sample autocorrelations both for original process and for squared process. It is verified that standard errors of sample autocorrelations for TAGARCH models are significantly different from unity for lower lags and they are exponentially converging to unity for higher lags. Furthermore they are shown to be asymptotically dependent while being independent of standard GARCH models. These results will be interesting in the light of the fact that TAGARCH processes are serially uncorrelated. A simulation study is reported to illustrate our results.
