The present study aimed to investigate the effects of maternal factors on body weight at hatching (day-old) and at six weeks of age in a commercial broiler line. A total of 6,765 records on body weight at day-old (BWTDO) and 115,421 records on body weight at six weeks of age (BWT6W), originated from a commercial broiler line during 14 generations, were used to estimate genetic parameters related to the effects of maternal traits on body weight of chicks immediately after hatch or six weeks thereafter. The data were analyzed using restricted maximum likelihood procedure (REML) and an animal model with DFREML software. Direct heritability ($h^{2}{_a}$), maternal heritability ($h^{2}{_m}$), and maternal environmental variance as the proportions of phenotypic variance ($c^{2}$) for body weight at day-old were estimated to be 0.050, 0.351, and 0.173, respectively. The respective estimated values for body weight at six weeks of age were 0.340, 0.022, and 0.030. The correlation coefficient between direct and maternal genetic effects for six-week-old body weight was found to be -0.335. Covariance components and genetic correlations were estimated using a bivariate analysis based on the best model determined by a univariate analysis. Between weights at hatching and at six week-old, the values of -0.07, 0.53 and 0.47 were found for the direct additive genetic variance, maternal additive genetic variance and permanent maternal environmental variance, respectively. The estimated correlation between direct additive genetic effect influencing weight at hatch and direct additive maternal effect affecting weight at six weeks of age was -0.21, whereas the correlation value of 0.15 was estimated between direct additive maternal effect influencing weight at hatch and direct additive genetic effect affecting weight at six-week-old. From the present findings, it can be concluded that the maternal additive genetic effect observed for weight at six weeks of age might be a factor transferred from genes influencing weight at hatch to weight at six-week-old.

This study focused on the effects of family, individual characteristics of adolescents and coping behaviors on adolescent runaway. The major findings were as follows: 1. Adolescent who had higher level of family violence, lower level of communication with parent, family cohesion and adaptability, and resource adequacy perception reported higher scores in runaway. 2. Adolescents who had higher level of emotional distress, lower level of self-esteem and self-control tended to have higher scores in runaway. 3. There was a significant difference in adolescent runaway according to coping behavior styles. 4. Maladaptive coping behaviors were significantly associated with the runaway adolescent group. 5. Adaptive coping behaviors were not associated with both runaways and non-runaways group. 6. Communication with father had a direct effect on adolescent runaway and also indirect effects through emotional stress and maladaptive coping behavior. 7. Maladaptive coping behaviors had a direct effect on adolescent runaway but adaptive coping behavior had no effect. 8. Emotional stress had an indirect effect through maladaptive coping behavior on adolescent runaway. 9. Communication with father had a direct effect and an indirect effect through self-esteem of adolescents on the adaptive coping behavior. 10. Family adaptability had a direct effect on the adaptive coping behavior.

Though the brand management of trade shows are increasingly important, there are few studies with this theme. This research studies what factors have an effect on the brand loyalty of trade shows. To this purpose, we conduct empirical study on the relationship among perceived quality, perceived value, image of the trade show with attendee's satisfaction and loyalty of trade show. The results of this study are as follows: (1) Perceived quality has a direct effect on perceived value and satisfaction of trade show and indirect effect on attendee's loyalty of the trade show. (2) Perceived value has a direct effect on attendee's satisfaction and indirect effect on attendee's loyalty of the show. (3) Trade show image has a direct effect on perceived value, attendee's satisfaction and loyalty of the trade show. Especially, image has the greatest effect on attendee's satisfaction and loyalty of the show. This means that the trade show image a critical variable in the brand management of the show.

Purpose: The purpose of this study was to examine nurses' experience of workplace incivility from coworkers, supervisors, patients or patients' families, and doctors. The researcher identified the relationships among empowerment, burnout, and organizational commitment of hospital nurses. Methods: The sample included 415 hospital nurses. Data were collected through questionnaires and analyzed using SPSS and AMOS. Results: The average incivility score was 2.94 from doctors and 2.89 from patients or patients' families, higher than from supervisors (1.90) and coworkers (1.87). The variables affecting burnout included direct effect of empowerment (${\beta}$=-.46, p<.001), direct effect of patients or patients' family incivility (${\beta}$=.14, p<.001), direct effect of supervisor incivility (${\beta}$=.12, p<.001), and direct effect of doctor incivility (${\beta}$=.09, p<.001). The variables affecting organizational commitment were direct effect of burnout (${\beta}$=-.58, p<.001), indirect effect of empowerment (${\beta}$=-.23, p<.001), indirect effect of patients or patients' family incivility (${\beta}$=-.12, p<.001), indirect effect of supervisor incivility (${\beta}$=-.10, p<.001), and indirect effect of doctor incivility (${\beta}$=-.09, p<.001). Conclusion: The results indicate that incivility affecting nurses results in a high degree of burnout and a low degree of organizational commitment. Therefore, it is necessary to assess incivility cases and to hold workshops designed to curb incivility and establish healthy workplaces.

This study explored the longitudinal developmental paths of preschooler's external problem behaviors from infancy. Subjects consisted of 205 preschoolers (106 boys, 99 girls aged 4) and their mothers recruited for the 2009 in-depth Panel Study on Korean Children. Data were analyzed by descriptive statistics, correlations, and structural equation modeling using SPSS 18.0 (SPSS Co., Chicago, IL, USA), Amos 18.0 (SPSS Co., Chicago, IL, USA). The results were as follows: Maternal depression at preschooler's age 0 had a direct effect on maternal social parenting style at preschooler's age 0. Maternal social parenting style at preschooler's age 0 had a direct effect on preschooler's effortful control at age 1. Preschooler's effortful control at age 1 had a direct effect on preschooler's external problem behaviors at age 4. Marital conflict at preschooler's age 0 did not have a direct effect on preschooler's effortful control at age 1. The direct effects of maternal depression at preschooler's age 0 on preschooler's effortful control at age 1, and on preschooler's external problem behaviors at age 4 were not significant. In addition, direct effect of maternal social parenting style at preschooler's age 0 on preschooler's external problem behaviors at age 4 was not significant. This study showed that maternal psychological characteristics, marital conflict, maternal social parenting style and preschooler's effortful control in infancy should be considered simultaneously to explain the effect on preschooler's external problem behaviors.

The research objective was to find out how Total Quality Management (TQM) mediates antecedents of employee performance variables? The research was conducted with a quantitative approach while the research design was cross sectional. The research model was tested using the structural equation modeling approach with partial least square analysis tools to test the influence among research variables. The research sample consisted of 315 respondents who answered a questionnaire in August-September 2019 at manufacturing companies in East Java. The results showed that situational leadership did not affect employee performance, but did affect the successful implementation of TQM. The performance measurement system has no direct effect on employee performance. The performance measurement system has a direct effect on employee performance. Organizational culture has a direct effect on both employee performance and the application of TQM, so that the application of TQM can improve employee performance. TQM implementation variable acts as a mediation between situational leadership and organizational culture on employee performance. The relationship that was originally a direct influence turned into an indirect effect through TQM. The TQM variable is not proven to be an intervening variable between the performance measurement system and employee performance. There is a direct relationship between these two variables.

The paper aims to investigate whether foreign direct investment (FDI) has positive effect on the labour productivity in Vietnam. Labour productivity is the elemental determinant of a country's development level in long-term. In recent years, although increasing consistently, labour productivity of Vietnam remains low in comparison to other South East Asian countries. To identify the direction of effect and the level of effect of FDI and human capital on the labour productivity of Vietnam, Autoregressive Distributed Lag (ARDL) model was used to examine the effect of FDI and human capital on labour productivity in Vietnam from 1986 to 2014. The results of bounds test confirm the existence of cointegration among the variables. Further, the Toda and Yamamoto Granger causality test affirms that there is unidirectional causality running from foreign direct investment and human capital index to labour productivity. The empirical results provide strong statistical evidence that foreign direct investment and human capital has a positive impact on labour productivity in Vietnam in long-term. These findings imply that workers are expected to further improve their knowledge, skills and that policy-maker should establish concrete plans to increase human capital. Results from this study provide suggestion necessary for Vietnam to achieve sustainable development.
