EFFECTS OF EXPLICIT TIMING ON MATHEMATICS PROBLEM COMPLETION RATES IN AFRICAN-AMERICAN THIRD-GRADE ELEMENTARY STUDENTS

A multiple baseline design was used to evaluate the effects of Van Houten and Thompson's (1976) explicit timing procedure on problem completion rates and accuracy levels in African-American third-grade students. During the explicit timing phase, students were told that they were being timed and were instructed to circle the last problem completed at each 1-min interval. Results showed that the explicit timing procedure increased problem completion rates. A decreasing trend in percentage of problems correct also occurred. Exploratory data analysis suggested that decreases in accuracy were not caused by the explicit timing procedure and did not occur in students who had attained high levels of preintervention accuracy. Discussion focuses on recommendations for educators who wish to use timing procedures to increase students' rates of accurate responding.     

Predictors of Secondary School Completion Among Refugee Youth 8 to 9 Years After Resettlement in Melbourne,Australia

Being able to attend school and achieve an education is one of the most desired opportunities among resettled refugee young people. However, turning educational aspirations into reality is not straightforward. There is a large body of research documenting the barriers associated with educational achievement among refugees who resettle as teenagers, both in Australia and internationally. No studies, however, have identified the factors that predict completion of secondary school among resettled refugee youth over time. This paper reports the predictors of completion of secondary school among a cohort of 47 refugee youth resettled in Melbourne, Australia. Eight to 9 years after resettlement, 29 (62 %) had completed secondary school and 18 (38 %) had left school prior to completing year 12. Age on arrival and experiences of discrimination in Australia were significant predictors of secondary school completion. Older refugee youth (on arrival) and those who reported experiences of discrimination over the first 8 to 9 years in Australia were significantly less likely to complete secondary school. This longitudinal study confirms that, as a group, refugee youth are particularly at risk of not completing secondary school education, which can have an impact on their wellbeing and long-term socio-economic standing in their settlement country. Our study provides further evidence of the negative impact of discrimination on the educational outcomes of disadvantaged young people.

Weathering the storm: children's long-term recall of Hurricane Andrew

Children who experienced a highly stressful natural disaster, Hurricane Andrew, were interviewed within a few months of the event, when they were 3-4 years old, and again 6 years later, when they were 9-10 years old. Children were grouped into low, moderate, or high stress groups depending on the severity of the experienced storm. All children were able to recall this event in vivid detail 6 years later. In fact, children reported over twice as many propositions at the second interview as at the first. At the initial interview, children in the high stress group reported less information than children in the moderate stress group, but 6 years later, children in all three stress groups reported similar amounts of information. However children in the high stress group needed more questions and prompts than children in the other stress groups. Yet children in the high stress group also reported more consistent information between the two interviews, especially about the storm, than children in the other stress groups. Implications for children's developing memory of stressful events are discussed.     

Dorsal stream activation during retrieval of object size and shape

We investigated dorsal visual stream involvement in the retrieval of a variety of visual attributes of common objects, using functional magnetic resonance imaging. Seven subjects made binary decisions about the shape, color, and size of named objects during scanning. Bilateral parietal activity was significantly greater during retrieval of shape and size information than during retrieval of color information. Consistent with a domain-specific distributed model of semantic organization, the finding that dorsal stream activity is associated with size and shape retrieval, as compared with color retrieval, may indicate that both size and shape information are learned partly through dorsally mediated processes, such as visually guided grasping. These results demonstrate that both visual-processing streams (i.e., the ventral “what” pathway and the dorsal “where” pathway) are involved in the storage and/or retrieval of knowledge of object appearance but that, just as in vision, these two pathways may play different roles in conceptual processing.     

Perceptions of adulthood among Anglo and Latino parents

The transition to adulthood presupposes that a developing adolescent acquires a set of characteristics that enables him or her to perform expected adult behaviors. There is a gap in the literature in identifying these expected behaviors as they pertain to different cultural and racial groups. To fill this gap, parent-generated indicators of adulthood were studied, including the beliefs, behaviors, and attitudes that are either common or specific to Anglo and Latino parents. College students at an urban university in the Los Angeles area were recruited to enlist their parents to complete a questionnaire. Equal numbers from each ethnic group were surveyed. The results of this study indicate that Anglo participants defined adulthood in terms of independence significantly more often than Latino participants. Furthermore, Latino participants defined adulthood in terms of event-related markers, such as marriage, significantly more often than Anglo participants. This research points to the need to define adulthood in ways that reflect the ethnic diversity of the United States. The authors express their thanks to Russell Espinoza, Ileana Garoz, Anna Rivera, Sandra Samayoa, Gabriella Chavira, Maria Hernandez, Angel Lahr, and Kevin Kim for their invaluable assistance. An earlier version of this paper was presented at the 1997 meeting of the Western Psychological Association, Seattle.     

Ability to Manage Resources in the Impression Management Process: The Mediating Effects of Resources on Job Performance

Purpose

Based on the conservation of resource (COR) theory, we hypothesize that one’s ability to manage resources will moderate the relationship between the use of positive impression management (IM) and other desired resources, such that those able to manage resources will have higher levels of social resources (reputation and leader–member exchange) when expending energy through the use of positive IM tactics. Additionally, we expect higher levels of these social resources will lead to higher performance ratings.

Design/Methodology/Approach

We conducted a two-study replication. In Study One (n = 213), data were collected at two time points. Dyadic data were collected in Study Two (n = 83) to demonstrate consistent relationships across two different study designs.

Findings

Our findings indicate that the ability to manage resources is associated with higher levels of social resources, such as reputation and high quality LMX, which are ultimately associated with positive workplace outcomes, specifically job performance.

Implications

The ability to manage one’s resources is a crucial individual capability that allows individuals to secure positive work outcomes. This research highlights the utility of resources management initiatives that organizations might want to provide to their workers, such as equipment, support personnel, and the autonomy to pace oneself during hectic endeavors.

Originality/Value

We investigate an individual difference in the COR process, which is lacking in the current literature (Hobfoll and Shirom 2000). Further, this research examines COR consequences beyond stress-related outcomes. Lastly, our research highlights the value of examining IM in light of COR theory.

     

The value of stress-management interventions in life-threatening medical conditions

Emotional stress has been associated with the development and progression of several chronic medical conditions. Recently, researchers have assessed the impact of stress-management interventions on patients' psychological functioning, quality of life, and various disease outcomes, including survival. This review summarizes the value of stress-management techniques in the treatment of two important, life-threatening conditions: coronary heart disease and cancer. Results from randomized clinical trials indicate that psychological interventions can improve patients' psychological functioning and quality of life. However, there is limited evidence to suggest that these interventions significantly reduce morbidity and mortality.     

The epistemology and ethics of chronic disease research: Further lessons from ECMO

Robert Truog describes the controversial randomized controlled trials (RCTs) of extracorporeal membrane oxygenation (ECMO) therapy in newborns. Because early results with ECMO indicated that it might be a great advance, saving many lives, Truog argues that ECMO should not have been tested using RCTs, but that a long-term, large-scale observational study of actual clinical practice should have been conducted instead. Central to Truog’s argument, however, is the idea that ECMO is an unusual case. Thus, it is an open question whether Truog’s conclusions can be extended to other areas of medical research. In this paper, I look at epistemological and ethical issues arising in the care of patients with chronic diseases, using ECMO as a starting point. Both the similarities and the dissimilarities of these two cases highlight important issues in biomedical research and support a conclusion similar to Truog’s. Observational studies of clinical practice provide the best evidence to inform the treatment of patients with chronic disease.     

Making the Best of a Bad Situation: Proactive Coping with Racial Discrimination

Proactive coping with racial discrimination takes three forms: self-focused coping, situation-focused coping, and avoidance. Overall, African Americans used self-focused coping more than situation-focused coping or physical avoidance, though there were interesting differences between retrospective recall of racial discrimination and daily reports. Relative to reports during the diary week, when recalling how they typically dealt with racial discrimination, African Americans overestimated their use of situation-focused strategies and underestimated their use of self-focused strategies. For both retrospective and daily reports, proactive coping was positively related to primary appraisals of harm but unrelated to secondary appraisals of resources. African American identification, but not stigma consciousness or optimism, was uniquely associated with proactive coping. We discuss the potential benefits and limitations of proactive coping with racial discrimination.
