Thesis advisor: Jacqueline Lerner / Understanding the family and school factors that lead to Latino children's social competence in the United States is a critical issue for the school success of our expanding Latino population. Using a Latino subsample of the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N = 3,072), this study examined socioeconomic status, home language, and parental stress in relation to parenting behaviors as predictors of kindergarten children's social skills in the classroom. Spanish instruction in the classroom was investigated as a moderator of the relationship between parental stress and parenting behaviors. Using regression analyses, it was found that higher socioeconomic levels were associated with greater levels of parental warmth and structured rules and routines in the family. Spanish as home language was related to lower levels of harsher forms of discipline. Both marital stress and parenting stress were predictive of harsher forms of discipline and decreased structured rules and routines in the family. Marital stress alone was related to decreased levels of parental warmth. Parenting behaviors were predictive of kindergarten children's social skills. Harsher forms of discipline were related to decreases in children's self-control and interpersonal skills. Increased levels of family rules and routines were positively related to children's self-control and interpersonal skills. Evidence was found for the mediational role of parenting behaviors to children's social skills. Discipline mediated the relationship between marital stress and children's self-control and interpersonal skills. Discipline also mediated the relationship of parenting stress to children's interpersonal skills. Finally, structured rules and routines in the family mediated the relationship of marital stress to interpersonal skills. Support was found for Spanish instruction in the classroom as a moderator for the relationship of parenting stress to negative parenting behaviors. Spanish in the classroom was associated with higher levels of parental warmth and lower levels of harsh discipline, in spite of parenting stress. This result highlights the importance of providing Spanish language resources in our school systems to promote Latino children's social competence. / Thesis (PhD) — Boston College, 2011. / Submitted to: Boston College.

The present study used a discounting task with differing contextual variables to examine how variables effect discounting between studies and future health related behaviors. Thirty nine participants completed two discounting questionnaires, each included hypothetical food choices paired with a weight loss or stable weight. Participants were instructed to complete each survey based on either their current weight or a gain of 75 pounds, and each survey included two identical hypothetical menu options. One menu incorporated low calorie foods, while the other incorporated moderately healthy foods, and participants were instructed to select the menu they preferred based on weight loss/no weight loss and hypothetical weight presented in instruction. Visual analysis of the results showed a difference in discounting across the conditions; participants appeared to be more impulsive at their current weight. At normal weight, visual analysis of the switch values show that the proportional value of the switch ranged from 1.0 at the lowest proportional delay level to .75 at proportional delay 1. In the hypothetical weight gain condition, this occurred at a level of .95 at the lowest proportional delay and .75 at delay 1. In a visual analysis of AUC comparisons, participants’ scores are higher in the 75 pound weight condition than the normal weight condition, and farther from 0 in the 75 pound weight condition.

This thesis presents the results of three studies that extend understanding of ethical decision making in negotiation. First, by comparing how Chinese and Australian negotiators think about contextual variables in an interpretive study, an extended model of ethical decision making in negotiation is offered. This study suggested differences in how codes of ethics and perception of the other party were understood as well as a shared understanding of the influence of the legal environment across the two cultures. Importance of organisational goals and personal and business reputation also emerged as important variables in negotiators' ethical decision making. The next study began testing the extended model with an investigation of the interaction between culture and closeness of the relationship with the other party using the SINS scale (Robinson, Lewicki, & Donahue, 2000). It was found that Chinese negotiators generally rated ethically ambiguous negotiation tactics as more appropriate than Australians, and that Chinese differentiated more in their ratings of appropriateness according to the social context. In the test for metric equivalence of the SINS scale, this study found that the existing approach of inductively deriving types of ethically ambiguous negotiation tactics based on ratings of perceived appropriateness is flawed since patterns of ratings are likely to vary across groups of negotiators. In light of this, a new typology of ethically ambiguous negotiation tactics is offered based on an a priori identification of conceptually distinct types of tactics. This new inventory of items represents the first step in the process of producing a cross-culturally generalisable scale of ethically ambiguous negotiation tactics.
