Effects of positive attitude and optimism on wage and employment: A double selection approach

Using two samples from the 1979 National Longitudinal Survey of Youth (NLSY79), a longitudinal data set from the United States, and following a double selection approach, the current study estimates the worker's employment and wage equations simultaneously with positive attitude and optimism as additional explanatory variables. Modeling employment as a bivariate decision process, the study examines different factors that influence the worker's labor market participation decision, the employer's hiring decision and the wage rate. The study finds the evidence that the worker's positive attitude and optimism affect the worker's employment probability from different angles: the former through the participation decision and the latter through the hiring decision. Following an alternative approach, this study also provides strong support to the earlier finding that positive attitude affects the worker's wage positively. Interestingly, the effects of attitude variables on the worker's wage are found to be quite comparable in magnitude to the wage effects of the traditional human capital variables.     

Fertility of Australian birth cohorts: Components and differentials

The paper examines the change in the level and pattern of fertility that took place in the post-1971 period, and the downward completed fertility of successive generations of Australian women born since 1933–37. The change in cohort fertility is assessed in terms of the cohort parity progression ratios, and the four components of cohort total fertility: the proportion of women who proceeded to have a birth, mean age at first birth, mean age at last birth, and average interbirth interval for women who had at least two births. The other aspects discussed are the cohort fertility differentials and the implications of the current trends for future fertility in Australia.     

Managing urban growth and development in the Riyadh metropolitan area, Saudi Arabia

The paper examines public sector management of urban growth and development in the Riyadh Metropolitan Area, Saudi Arabia. The focus of the paper is on institutional capacity building and development intervention. The paper traces changes in public sector management structures and development activities over the history of the city with the aim of assessing development impact and identifying forces that have shaped the evolving state of urban management. The paper notes that urban management has significantly improved with time but the persistence of urban problems coupled with projections of future growth point to the need for further improvements. The paper, in conclusion, while acknowledging the utility of the metropolitan development strategy (MEDSTAR) being formulated for the city, points to the need for broader administrative reform to improve the ability to cope with long-term challenges of growth in the city. Some issues that reform could address are suggested.     

Effects of positive attitude and optimism on employment: Evidence from the US data

Using samples from the National Longitudinal Survey of Youth (NLSY) and following a bivariate probit approach, the current study estimates the worker's employment probability equations in both cross-sectional and panel data frameworks. The study demonstrates that the employment of the worker, which depends on both the worker's labor market participation decision and the employer's hiring decision, is determined partly by the positive and optimistic attitude of the worker. The effects of these attitude variables on both decisions are even larger than the effects of standard human capital variables. The study further demonstrates that the attitude variables affect employment probabilities of men and women differently because their effects on participation and hiring decisions are different.     

Money matters: An exploratory study of the socio-cultural context of consumption, saving, and investment patterns

This study focuses on 36 professional South Asian (Indian) families in a metropolitan city in Canada in order to understand motives for financial behavior. In accordance with the Hindu world view, Indians view wealth acquisition as necessary for the natural progression of an individual's life and take a long view of time when it comes to investment decisions. Their primary purpose is to invest money in order to provide for their children's education. Their cultural roots allow them to take a long-term view and makes them more risk tolerant. Although these families take economic criteria into account, such criteria alone do not fully explain their consumption, saving, and investment patterns. It would appear that their need for saving determines their consumption, not the other way around. To understand their financial behavior, one has to identify the cultural worlds in which Indians live. The study highlights the importance of understanding the socio-cultural context of decisions that may appear to be purely economic decisions at first sight.     

A Test for bivariate exponentiality against bhnbue alternative

A test statistic for testing bivariate expotentiality against the alternative representing the property ‘bivariate harmonic new better than used in expectation’ (Bhnbue) is developed.     

A unified approach for estimation and detection of outliers

Two two-stage procedures RD_M-ESD and RD_M-KUR to detect outliers from normal samples are considered. Their powers for n=20 (10)60, k=2(1)(n/5) are computed and compared. Percentage points of these procedures are presented.Two examples to illustrate the use of these procedures are also given.     

Role of parents in the development of social competency among adolescents

ABSTRACT

Adolescence, the transition period between childhood and adulthood, is a period of great risks and possibilities. Teen years comprise a period of intense growth not only physically but also morally and intellectually. The adolescence has traditionally been portrayed as a state of internal civil war. In the period of revolutionary change, social competence refers to the social, emotional, and cognitive skills and behaviors that child need for successful social adaptation. So in this critical period of change, parents have to deal their child with proper guidance, love, and sympathy to enable his or her to tackle various problems of adolescence of his or her life. This may successfully bring about the welfare of the society and help the child to grow into the distinct individual. In this paper, an attempt is made to explore the connection between parental role and development of social competence among adolescents using effective tools covering various dimensions. A sample of 160 adolescent students of various schools of Ajmer district of India in the age group of 13 to 18 years was randomly selected covering male-female students, rural-urban students, and students of government and private schools. Tools developed for parental role scale and social competence scale were administered. Various statistical techniques were applied on the data collected. ANOVA test results show that three groups of parental role, e.g., higher parental role group, average parental role group, and lower parental role group, significantly differ in achieving social competence. Based on the findings, the paper presents educational implications.     

A Simple Method for Computing the Arl of [ILM0001]-Charts with Zone Tests

In practice the [ILM0002]-chart has been augmented with one or more zone tests to improve the sensitivity of detecting small shifts in the process mean. The average run length (ARL) is one of the indices used to evaluate the performance of control chart procedures. Two unified patterns of transition probability matrices and four closed form expressions of the ARL are found based on the Markov Chain approach. These closed form expressions can be used for computing the ARL for both one-sided and two-sided [ILM0003]-charts with zone tests.
