Geophysical variables and behavior: LXVIII. Distal and lunar variables and traffic accidents in Saskatchewan 1984-1989.

The daily total number of traffic accidents and traffic accident severity for the years 1984 to 1989 in Saskatchewan were analyzed to estimate relationships with day of the week, season of the year, and various lunar variables (lunar phase, distance of the moon from the earth, and moon-sun tidal index). A regression model with both a linear term and a trigonometric term was fitted to the data. No relationship between lunar cycles and total accidents or severity of accident was found. A larger number of total accidents was found during the winter months and weekends; however, more severe accidents tended to occur during the summer months. A slight linear trend was uncovered for total accidents over the time period under consideration.     

Moon and Media: Lunar Cycles and Television Viewing

A review of the literature reveals that the possibility of lunar influence on various aspects of human health and behavior has long been taken seriously in established scientific journals. The purpose of this article is to extend this perspective to media research by focusing on the relation between lunar cycles and television viewing behavior. In preliminary analyses performed on a data set containing daily television viewing figures and moon and weather information for Flanders in 1993 (over a 12-month period), a weak but significant positive relation between "the amount of television viewing" and "the percentage of the moon illuminated" was found. However, subsequent analyses of a data set containing daily television viewing figures and moon information for Flanders, Denmark, Norway, and The Netherlands in 2002 (over a 12-month period), revealed a weak positive correlation between "television viewing time" and "percentage of the moon surface illuminated" only in Denmark. Given these inconsistent results, it is concluded that further investigation is needed. Future studies should investigate data over a longer period of time, include additional moon variables (i.e., amount of moonlight), explicitly test the moon-sleep deprivation-television viewing hypothesis, control for other environmental factors (e.g., weather conditions), and search for alternative explanations for a possible relation between amount of television viewing and the moon cycle.     

TEMPORAL AND CLIMATIC VARIABLES IN NATURALISTIC OBSERVATION1

Home-observation data on 5- to 7-yr-old boys collected over 2 yr were examined for systematic variations in rates of desirable and undesirable behaviors associated with several temporal and climatic variables. Significant effects associated with time of day, day of the week, precipitation, and temperature were found. No significant effects on the naturalistic observation data were found for environmental factors associated with lunar phase. It was noted that the correlational nature of the findings did not obviate the necessity for control of the influence of temporal and climatic variables. Several methodological strategies for such control were discussed.     

Trait Goal Orientation, Self-Regulation, and Performance: A Meta-Analysis

Purpose

The purpose of this paper is to meta-analytically examine trait goal orientation constructs and their relationships with the self-regulation variables of self-monitoring, self-evaluations, self-reactions, and self-efficacy as well as task performance across a range of contexts.

Design, Methodology, Approach

Data were gathered from published and unpublished research examining the goal orientation construct and self-regulation and/or task performance. Effect sizes from 102 research reports involving over 16,000 participants were included.

Findings

In general the mastery-approach goal orientation construct was positively related to the self-regulation and performance variables. Conversely, negative relationships were found between the performance-avoid goal orientation and those variables. Relationships between goal orientation and self-regulation tended to be higher compared to those found for goal orientation and performance. Overall, the findings support the discriminant validity of the three factors of goal orientation (mastery-approach, performance-approach, performance-avoid).

Practical Implications

Practitioners and researchers will benefit from learning that mastery-approach goal orientation consistently relates to self-regulation and task performance. The findings indicate that a mastery-approach goal orientation could serve as a meaningful predictor in selection processes or as an explanatory variable of motivation.

Originality/Value

The present study updates and expands upon past research by focusing on relationships of trait goal orientation across a variety of contexts. The results extend meta-analytic results to a wider range of self-regulatory variables.     

How Do Relationships Support Parenting? Effects of Attachment Style and Social Support on Parenting Behavior in an At‐Risk Population

The importance of supportive relationships for new parents has been the focus of both research and parenting interventions. Attachment style, typically viewed as a relatively stable trait reflecting one's comfort in social relationships, as well as social support, or one's perception of the social context, have both been found to be important for fostering engaged, involved parenting. Less is known, however, about how these variables work together to influence parenting behavior, especially in families at higher risk for negative child outcomes. Data were collected from 152 urban, predominantly African American, low-income parents when their children were 14 and 36 months of age. Results suggest that parents with more social support show greater increases in the frequency of positive parent-child activities over time, but that this effect is mediated by mothers' attachment style, specifically, their level of anxious/ambivalent attachment. Mothers with more social support tended to be less anxious/ambivalent about close relationships, and this in turn led to increases over time in the frequency of parent-child interactions. Mothers' tendency to avoid close relationships, however, while correlated with social support, was unrelated to changes in parenting behavior. Implications of these findings for program development, parenting, and the malleability of attachment style based on social context are discussed.     

Longitudinal Relations Between Depressive Symptoms and Life Satisfaction Over 15 Years

The longitudinal relationships between depressive symptoms and life satisfaction were examined using the random intercept cross-lagged panel model. This model allows the study of the relationship between the two variables both at the within-person and between-person levels. Data were obtained from the German Ageing Survey (DEAS). Analyses were conducted at lags of 3 (N = 8,492) and 6 years (N = 4,878), with data collected over a period of approximately 15 years. At the within-person level, the bidirectional associations between the two variables were significant in the 3-year lag analysis, whereas in the 6-year lag analysis, only life satisfaction predicted future depressive symptoms. An implication is that dissatisfaction with life may signal the possibility of developing depressive symptoms in the future. Increasing life satisfaction may act as a preventive measure against future depressive symptoms. Depressive symptoms may also be an indicator of future deterioration in subjective well-being.

     

MENTAL HEALTH OF TRAUMA-EXPOSED FIREFIGHTERS AND CRITICAL INCIDENT STRESS DEBRIEFING

Interest in critical incident stress debriefings for firefighters has grown over the last decade. Some researchers report that debriefings protect firefighters from stress-related disorders, including posttraumatic stress disorder (PTSD). Proponents of the interventions claim extraordinary need and success. Controlled and correlational studies have largely failed to demonstrate therapeutic effects, and some report iatrogenic effects. This study examined the relationships between debriefings and several mental health variables in a large sample of firefighters. Debriefing had a weak inverse correlation with negative affectivity and a weak positive correlation with positive world assumptions. No relationship was found between debriefing and PTSD.     

Use it or lose it: engaged lifestyle as a buffer of cognitive decline in aging?

Data from the Victoria Longitudinal Study were used to examine the hypothesis that maintaining intellectual engagement through participation in everyday activities buffers individuals against cognitive decline in later life. The sample consisted of 250 middle-aged and older adults tested 3 times over 6 years. Structural equation modeling techniques were used to examine the relationships among changes in lifestyle variables and an array of cognitive variables. There was a relationship between changes in intellectually related activities and changes in cognitive functioning. These results are consistent with the hypothesis that intellectually engaging activities serve to buffer individuals against decline. However, an alternative model suggested the findings were also consistent with the hypothesis that high-ability individuals lead intellectually active lives until cognitive decline in old age limits their activities.     

Containment theory and juvenile delinquency: a reevaluation through factor analysis

All seven variables of containment theory were operationalized for questionnaires. Data were collected from 677 adolescents in a variety of high schools and correctional institutions, and divided into categories by race and sex. Factor analysis indicated that the structure of the relationships among the seven containment variables and delinquency was substantially different among black females.     

Informal Support from a Pastor and Change in Hope During Late Life

The purpose of this study is to see if informal emotional support from a pastor is associated with a greater sense of hope over time. Data from a nationwide longitudinal survey of older adults are used to test a conceptual model that contains the following relationships: (1) older people who encounter more stressful life events will seek out more informal emotional support from a member of the clergy, (2) older people who receive more support from a pastor will experience a stronger sense of God-mediated control (i.e., the belief that it is possible to work together with God to solve problems), and (3) increases in God-mediated control over time will be associated with increases in hope over time. The data provide support for each of these relationships.     

WHEN TO BEAR FALSE WITNESS: AN EVOLUTIONARY APPROACH TO THE SOCIAL CONTEXT OF HONESTY AND DECEIT AMONG COMMERCIAL FISHERS

Abstract. This paper uses an evolutionary perspective to identify variables influencing compliance with moral codes about honest communication. Data on over one thousand radio conversations among lobster fishers in two harbors in Maine are compared in regard to the sharing of information. The sharing of accurate information is found to be significantly more frequent in the harbor that is more integrated by reciprocally altruistic relationships. This is consistent with the view that moral systems are systems of indirect reciprocity, but it also suggests that humans have evolved to base their compliance with moral codes on cues from their social environment.     

The Sibling Resource Dilution Theory: An Analysis

In this study, I examined relationships between sibling variables and children's family educational resources at different levels of family social status and children's intellectual ability. Data were collected from 900 eleven-year-old Australian children (450 boys, 450 girls) and their parents. Relationships among the variables were examined by plotting regression surfaces generated from models that included terms to test for possible linear, interaction, and curvilinear associations. Although results from some of the regression models provided tentative support for the sibling resource dilution theory, overall results suggest that acceptance of the theory must be treated with some caution. In general, the analysis indicated the possible complexity of relationships between sibling variables and family educational resources.     

The Relationships Between First- and Second-Order Measures of Cultivation

In the research literature on the cultivation hypothesis, there are two types of measures: first order and second order. First-order measures require respondents to provide estimates of occurrences. Second-order measures assess respondents’ attitudes. This study seeks to determine whether this measurement distinction results in operationalizations that are independent or related to one another. It was found that the two are related to a weak degree at a general level, but stronger relationships are found on a contingent analysis. Subgroups defined by relevant situational variables and certain general variables (such as IQ and especially age) reveal significant differential patterns of relationships. Also, evidence was found of an asymmetric pattern on several topics where first-order estimates usually form a basis for second-order beliefs.     

Quality of mental health services and method of payment: an empirical study

Data from a sample of clinicians are examined to study the relationship of the lower socio-economic client and therapist. Therapist practice variables are regressed on variables measuring client income and contrasting client's use of Medicaid with the use of private insurance or out-of-pocket funds. It is found that therapist practice variables can predict a significant proportion of the variance of these criterion variables. These relationships and their implications for the therapeutic needs of indigent clients with less severely impaired conditions are discussed.     

Structural equation models of relationships between exercise and cognitive abilities

Data were obtained from 300 men and women aged 55 to 91. Separate structural equation models of relationships between physical exercise and 3 cognitive performance variables--reaction time, working memory, and reasoning--fit the data well. Other variables in the models were age, health, education, and morale. Age and exercise affected each performance variable directly; education had a direct effect on reasoning only. There were also indirect effects of age and health on performance variables, mediated through exercise. The main hypothesis of the study, that exercise contributes to performance, was supported. A large decrease in model fit resulted when the path from exercise to each performance variable was deleted. Hypotheses that age-related deficits are primarily accounted for by lack of exercise or by poor health were not supported.     

Job Satisfaction Among Married Working Women

Data from a recent national opinion survey were used to evaluate an array of work and nonwork variables in terms of their relationships to reported job satisfaction of married working women. Women's job satisfaction was found to be related to such variables as life satisfaction, age, and importance of job income but unrelated to such indices as race, educational level, occupational prestige, income level, and attitude toward women working.     

The role of goal orientation following performance feedback

This study examined the relationship of goal orientation and performance over a series of 2 challenging performance events. After providing performance feedback on the 1st event, the authors found that the relationship between a learning goal orientation and performance remained positive for the 2nd event, the relationship between a proving goal orientation and performance diminished from a positive to a nonsignificant level, and the relationship between an avoiding goal orientation and performance remained negative. Data analysis also indicated that the relationships between the 3 goal orientation dimensions and the performance event were differentially mediated by goal setting, self-efficacy, and effort.     

Prediction of foot clearance parameters as a precursor to forecasting the risk of tripping and falling

Tripping and falling is a serious health problem for older citizens due to the high medical costs incurred and the high mortality rates precipitated mostly by hip fractures that do not heal well. Current falls prevention technology encompasses a broad range of interventions; both passive (e.g., safer environments, hip protectors) and active (e.g., sensor-based fall detectors) which attempt to reduce the effects of tripping and falling. However the majority of these interventions minimizes the impact of falls and do not directly reduce the risk of falling. This paper investigates the prediction of gait parameters related to foot-to-ground clearance height during the leg swing phase which have been physically associated with tripping and falling risk in the elderly. The objective is to predict parameters of foot trajectory several walking cycles in advance so that anticipated low foot clearance could be addressed early with more volitional countermeasures, e.g., slowing down or stopping. In this primer study, foot kinematics was recorded with a highly accurate motion capture system for 10 healthy adults (25-32 years) and 11 older adults (65-82 years) with a history of falls who each performed treadmill walking for at least 10 min. Vertical foot displacement during the swing phase has three characteristic inflection points and we used these peak values and their normalized time as the target prediction values. These target variables were paired with features extracted from the corresponding foot acceleration signal (obtained through double differentiation). A generalized regression neural network (GRNN) was used to independently predict the gait variables over a prediction horizon (number of gait cycles ahead) of 1-10 gait cycles. It was found that the GRNN attained 0.32-1.10 cm prediction errors in the peak variables and 2-8% errors in the prediction of normalized peak times, with slightly better accuracies in the healthy group compared to elderly fallers. Prediction accuracy decreased linearly (best fit) at a slow rate with increasing prediction horizon ranging from 0.03 to 0.11 cm per step for peak displacement variables and 0.34 × 10(-3) - 1.81 × 10(-3)% per step for normalized peak time variables. Further time series analysis of the target gait variable revealed high autocorrelations in the faller group indicating the presence of cyclic patterns in elderly walking strategies compared to almost random walking patterns in the healthy group. The results are promising because the technique can be extended to portable sensor-based devices which measure foot accelerations to predict the onset of risky foot clearance, thus leading to a more effective falls prevention technology.     

A lengthy look at the daily grind: time series analysis of events, mood, stress, and satisfaction

The present study investigated processes by which job stress and satisfaction unfold over time by examining the relations between daily stressful events, mood, and these variables. Using a Web-based daily survey of stressor events, perceived strain, mood, and job satisfaction completed by 14 university workers, 1,060 occasions of data were collected. Transfer function analysis, a multivariate version of time series analysis, was used to examine the data for relationships among the measured variables after factoring out the contaminating influences of serial dependency. Results revealed a contrast effect in which a stressful event associated positively with higher strain on the same day and associated negatively with strain on the following day. Perceived strain increased over the course of a semester for a majority of participants, suggesting that effects of stress build over time. Finally, the data were consistent with the notion that job satisfaction is a distal outcome that is mediated by perceived strain.     

Recalled early maternal bonding and mother‐ and self‐related attitudes in young adult daughters: A cross‐cultural study in India and Belgium

The quality of child–parent relationships remains a vital aspect of development through the entire life span. Early childhood attachment develops into a lasting adult attachment bond in which the balance between caregiving and care‐receiving changes over time. Among young adult women a model was examined on the relationship of recalled early maternal bonding with (1) the current relationship with one's mother represented by variables such as adult attachment, filial responsibility and filial concern, and (2) self‐related attitudes represented by orientation to life and satisfaction with life. Participants were female university students from two quite different societies, India and Belgium, including 150 Hindi‐speaking and 150 English‐speaking students in India and 183 Dutch‐speaking students in Belgium. Instruments used were the Parental Bonding Instrument, the Adult Attachment Scale, a self‐constructed Filial Responsibility Scale, the Filial Anxiety Scale, the Orientation to Life Questionnaire, and the Satisfaction With Life Scale. Across the three languages and two cultures we first tested the construct/structural equivalence of the scales by means of exploratory factor analysis and congruence analysis. Results indicated that psychometric conditions of equivalence held for most instruments. In order to examine relationships between the variables, a LISREL path analysis was conducted across the three samples. A model closely similar to the theoretically postulated model was found to show a good fit with invariant parameters in the three samples. As expected, recalled early maternal bonding of young adult women appeared to have an impact on the current relationship with their mother and on aspects of their personal life experiences. Thus, the influence of recalled early maternal bonding on variables reflecting the relationship with one's mother and on self‐related variables were brought together in a single model that showed a good fit in all three samples.
