This work examines reemployment processes through the use of event history unemployment data in the United States. Two aspects of these processes, the duration of unemployment and changes in the reemployment rate, are modelled and analyzed in terms of individual characteristics and their structural positions in the labor market. The secondary labor market is a competitive market in which unemployment occurs because people quit their jobs to devote more time in search for better jobs. Using search theory, the rate of reemployment has a positive time dependence as the searcher lower her reservation wage with the passage of time. By contrast, the primary market is characterized by long-term employment relations which reduce voluntary turnovers but generate layoffs temporarily. Relying on contract theory, because workers on temporary layoffs wait for recall, reemployment rates have a constant time dependence. Empirical results of unemployment durations indicate that reemployment processes are influenced by individual's positions in dual labor market structures. While the analysis suggests that the amount of search reemployment seems to be positively related to the degree of competitiveness of a market, somewhat weaker results are noted in the search reemployment processes in competitive markets.

Professions with librarianship can be found in various fields. It includes all different kinds of libraries, including academic, public, special, and school libraries. Moreover, there are national and commercial information distribution bodies, and other bodies supporting the national body such as library automation companies, library supply companies, and library outsourcing companies. Careers of those who have studied in library and information science could be developed in all these fields. High flexibility and labour turnover can be expected due to the wide range of career fields. Nevertheless, there have been very little studies reflecting the reasons of high level of turnovers and flexibility in librarian workforce. Therefore, this paper invastigates career movement and development of librarian as a foundation stone of further researches. It also analyzes career development process of librarians, including career paths of those working in libraries and other related areas, their efforts for career development, factors influencing their career movements.

The purpose of this study was to investigate the moderating effects of self-efficacy on the relationship between workplace incivility and burnout, turnover intention of early childhood teachers. Data were collected from 565 early childhood teachers on INC, BUN, TUR and SEF which then were analyzed using correlation and multiple regression. The major findings of this study were as follows: First, workplace incivility was positively related to burnout and turnover intention. Second, workplace incivility was negatively related to self-efficacy. Third, self-efficacy was negatively related to burnout and turnover intention. Fourth, self-efficacy had moderational effects on the relationships between workplace incivility and burnout and between workplace incivility and turnover intention. The above findings demonstrate that workplace incivility affects both burnout and turnover intention.of early childhood teachers. Thus, policy to manage incivility in order to lessen burnout and turnovers should be considered. Additionally, programs that enhance self-efficacy should be developed and carried out.

The purpose of this study is to present and identify the relationship for the effects of performance-based human resource practices on the organizational effectiveness with focusing on small and medium-sized enterprises around Shandong province of China. The performance-based human resource practice factors include selective employment system, education training system, evaluation system, compensation system and the career promotion ladder opportunity system. As a result, among ten hypotheses, six hypotheses turned out to be the meaningful approaches. In addition there exist some human factors that interfere with the fairness of the evaluation due to the regional and personal factors, assessment system difference among firms. Finally the compensation system and organizational investment for increasing or decreasing will critically affect the enthusiasm of the staff members of firms, and the less invested for thema, the greater the likelihood of their turnovers.

Objectives: Subjective well-being is a representative indicator of quality of life. Work and life are not separated, and work itself is a part of life. The purpose of this study was to confirm the effect of psychological resources such as self-esteem, self-efficacy, GRIT, and resilience on the subjective career success and subjective well-being in dental hygienists. Methods: From November 12, 2020 to December 30, 2020, an online survey was conducted on 650 dental hygienists, and data from 630 were analyzed. For the analysis, independent two-sample t-test and one-way ANOVA were performed, and the confirmatory factor analysis and measurement model, construct validity, construct reliability, convergent validity, and discriminant validity were confirmed. This was verified using a structural equation model. SPSS 18.0 and AMOS 18.0 were used for the statistical analyses; p<0.05 were considered statistically significant. Results: The final model fit was found to be suitable. There was no significant difference in subjective career success with respect to the personal characteristics and career characteristics, except for total career and number of turnovers. There was no significant difference in subjective well-being according to personal characteristics and career characteristics. Psychological resources such as self-esteem, self-efficacy, GRIT, and resilience were significant for subjective career success (p<0.05, R²=0.637). Subjective career success was significant for subjective well-being (p<0.05, R²=0.378). Among the psychological resources, self-esteem had both direct and indirect effects on subjective well-being (p<0.05). Conclusions: Positive psychological resources, rather than external conditions, are an important prerequisite for subjective career success and subjective well-being. Thus, it is proven that work is a part of life.

Using the plant level panel data on Korean manufacturing during 1990-98 period, this study tries to assess the role of entry and exit in enhancing aggregate productivity, both qualitatively and quantitatively. Main findings of this study are summarized as follows. First, plant entry and exit rates in Korean manufacturing seem quite high: they are higher than in the U.S. or several developing countries for which comparable studies exist. Second, in line with existing studies on other countries, plant turnovers reflect underlying productivity differential in Korean manufacturing, with the "shadow of death" effect as well as selection and learning effects all present. Third, plant entry and exit account for as much as 45 and 65 percent in manufacturing productivity growth during cyclical upturn and downturn, respectively. The findings of this study show that the entry and exit of plants has been an important source of productivity growth in Korean manufacturing. Plant birth and death are mainly a process of resource reallocation from plants with relatively low and declining productivity to a group of heterogeneous plants, some of which have the potential to become highly efficient in future. The most obvious lesson from this study is that it is important to establish policy or institutional environment where efficient businesses can succeed and inefficient businesses fail.

This study investigates the influence of the developing and decaying El $Ni{\tilde{n}}o$-Southern Oscillation (ENSO) on the relation between typhoon intensity and its formation. From the long-tenn data of 57 years ($1950{\sim}2006$), we first defined the developing El $Ni{\tilde{n}}o$ years and the neutral years. During the developing El Nino years, the typhoon intensity has a strong relationship with formation region of the tropical cyclone, which results in an increase of the accumulated cyclone energy and intensity of energy of typhoon. During the developing El $Ni{\tilde{n}}o$ year based on $Ni{\tilde{n}}o$ 3.4 SST, the locations for the formation of the category 4+5 typhoon move to the eastward region. The genesis potential function and the low-level cyclonic vorticity have an important role on the formation of strong tropical cyclones, which eventually develop as a typhoon class. In this study, the dynamic potential (DP) function (Gray, 1977) and EOF 1 and EOF 2 time series (RMM 1 and RMM 2) of real-time multivariate MJO (Wheeler and Hendon, 2004) are used to measure the genesis potential and the low-level cyclonic vorticity, respectively. To investigate the influence of the developing and decaying ENSO, we defined the Type I case of the decaying El $Ni{\tilde{n}}o$ that turnovers to La Nina, and the Type II case of the recovering years to the neutral condition. During the decaying El $Ni{\tilde{n}}o$ years as Type I, the locations of the strong DP, RMM 1 and RMM 2 move to the westward more prominently to induce retard of the strong typhoon developing.
