Determinants of economic well-being among U.S. farm operator households

AGRICULTURAL ECONOMICS, Issue 3 2007
Hisham S. El-Osta
Farm households; Composite measure of economic well-being; ARMS data Abstract Participation in government programs has a mild impact on the economic well-being of U.S. farm households. Major factors that determine farm household prosperity are the primary operator's education level and ethnicity, education level of the spouse, and other characteristics such as forward purchasing of inputs, use of contract shipping of products, having a succession plan, farm ownership, and location in a metro area. This article uses the 2001 Agricultural Resource Management Survey (ARMS) as well as relative and an absolute measure to assess U.S. farm households' economic well-being. The relative measure compares the income and wealth position of farm households relative to median income and median wealth of the general population. The absolute measure adds annualized wealth to a farm household's income. [source]


Age-Related Changes in Drinking Patterns From Mid- to Older Age: Results From the Wisconsin Longitudinal Study

ALCOHOLISM, Issue 7 2010
Rachel C. Molander
Background:, Drinking has generally been shown to decline with age in older adults. However, results vary depending on the measure of alcohol consumption used and the study population. The goals of this study were to (i) describe changes in drinking in a current cohort of older adults using a variety of measures of drinking and (ii) examine a number of different possible predictors of change. Methods:, This is a longitudinal study of a community-based sample surveyed at 2 time points, ages 53 and 64 years. We estimated a series of logistic regressions to predict change and stability in drinking categories of nondrinking, moderate drinking, and heavy drinking. Linear regressions were used to predict change in past-month drinking days, past-month average drinks per drinking day, and past-month total drinks. Results:, From age 53 to 64, average drinks per drinking day and heavy drinking decreased. Frequency of drinking increased for men and women, and total drinks per month increased for men. The most consistent predictors of drinking changes were gender, health, and education. Other factors predicted drinking change but were not consistent across drinking measures including: adolescent IQ, income, lifetime history of alcohol-related problems, religious service attendance, depression, debt, and changes in employment. Conclusions:, Heavy drinking decreases with age, but we may see more frequent moderate drinking with current and upcoming cohorts of older adults. Components of quantity and frequency of drinking change differently. Composite measures of total alcohol consumption may not be adequate for describing relevant changes in drinking over time. A number of factors predicted patterns of change in drinking and warrant further exploration. [source]


The Attentional Resource Allocation Scale (ARAS): psychometric properties of a composite measure for dissociation and absorption,

DEPRESSION AND ANXIETY, Issue 8 2010
R. N. Carleton M.A.
Abstract Background: Differences in attentional processes have been linked to the development and maintenance of psychopathology. Shifts in such processes have been described by the constructs Dissociation and Absorption. Dissociation occurs when external and/or internal stimuli are excluded from consciousness due to discrepant, rather than unitary, manifestations of cognitive awareness [Erdelyi MH. 1994: Int J Clin Exp Hypnosis 42:379,390]. In contrast, absorption can be conceptualized by a focus on limited stimuli, to the exclusion of other stimuli, because of unifying, rather than discrepant, manifestations of cognitive awareness. The Dissociative Experiences Scale [DES; Bernstein EM, Putnam FW. 1986: J Nerv Ment Dis 174:727,735] and Tellegen Absorption Scale [TAS; Tellegen A, Atkinson G. 1974: J Abnorm Psychol 83:268,277] are common measures of each construct; however, no factor analyses are available for the TAS and despite accepted overlap, no one has assessed the DES and TAS items simultaneously. Previous research suggests the constructs and factor structures need clarification, possibly including more parsimonious item inclusion [Lyons LC, Crawford HJ. 1997: Person Individ Diff 23:1071,1084]. The purpose of this study was to evaluate the factor structure of the DES and TAS and create a psychometrically stable measure of Dissociation and Absorption. Methods: This study included data from an undergraduate (n=841; 76% women) and a community sample (n=233; 86% women) who each completed the DES and TAS. Results: Exploratory factor analyses [Osborne JW (ed). 2008: Best Practices in Quantitative Methods. Los Angeles: Sage Publications Inc.] with all DES and TAS items suggested a 15-item 3-factor solution (i.e., imaginative involvement, dissociative amnesia, attentional dissociation). Confirmatory factor analyses resulted in excellent fit indices for the same solution. Conclusions: The items and factors were conceptualized in line with precedent research as the Attentional Resource Allocation Scale (ARAS). Comprehensive results, implications, and future research directions are discussed. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source]


CONCORDANCE OF THE CIRCADIAN CLOCK WITH THE ENVIRONMENT IS NECESSARY TO MAXIMIZE FITNESS IN NATURAL POPULATIONS

EVOLUTION, Issue 4 2008
Kevin J. Emerson
The ubiquity of endogenous, circadian (daily) clocks among eukaryotes has long been held as evidence that they serve an adaptive function, usually cited as the ability to properly time biological events in concordance with the daily cycling of the environment. Herein we test directly whether fitness is a function of the matching of the period of an organism's circadian clock with that of its environment. We find that fitness, measured as the per capita expectation of future offspring, a composite measure of fitness incorporating both survivorship and reproduction, is maximized in environments that are integral multiples of the period of the organism's circadian clock. Hence, we show that organisms require temporal concordance between their internal circadian clocks and their external environment to maximize fitness and thus the long-held assumption is true that, having evolved in a 24-h world, circadian clocks are adaptive.

Board Structure and Executive Compensation in the Public Sector: New Zealand Evidence

FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 4 2005
Steven F. Cahan
We provide evidence on the relation between board structure and CEO compensation in public sector corporations in New Zealand. Using a sample of 80 New Zealand public sector companies, we find that similar to private sector studies, CEO compensation is related to board size, whether the CEO sits on the board, and director quality. We also find that a composite measure of board structure is significant. We conclude that, similar to the private sector, board structure is important in constraining CEO pay. Moreover, our results suggest that private sector-style board can be effective in a public sector context. [source]


Temperament at 7, 12, and 25 months in children at familial risk for ADHD

INFANT AND CHILD DEVELOPMENT, Issue 4 2008
Judith G. Auerbach
Abstract As part of a longitudinal investigation of infants at familial risk for attention-deficit hyperactivity disorder (ADHD), mothers and fathers independently completed temperament ratings on their infants. In this paper, we examine the 7-, 12-, and 25-month temperament of 58 boys, 36 of whom were considered at familial risk for ADHD and 22 of whom were in the comparison group. Risk for ADHD was based on self-reported ADHD symptoms in the father. In addition, the influence of informant gender on temperament ratings was examined. The ADHD risk group received significantly higher scores for activity level and anger and lower scores for attentional shift, appropriate allocation of attention and inhibitory control. Their scores were also significantly lower on a composite measure of effortful control. Taken together, these findings offer support for the view of a link between early temperament and risk for ADHD. The only informant gender difference was for the activity level; mothers rated their sons as more active than did fathers. Copyright © 2008 John Wiley & Sons, Ltd. [source]


The Measurement of Success of Activity-Based Costing and Its Determinants: A Study within Canadian Federal Government Organizations,/L'évaluation Du Succès De La Comptabilité Par Activités Et Ses Déterminants: Étude D'Organismes Du Gouvernement Fédéral Du Canada

ACCOUNTING PERSPECTIVES, Issue 3 2007
Anne Fortin
ABSTRACT This research first measures the success of activity-based costing (ABC) implementation within Canadian federal government organizations along five constructs, which are the use and frequency of use of the ABC information, decision actions taken, financial improvements, evaluation by management as to overall success, and a composite measure of the four constructs. Second, it identifies the determinants of ABC success. The success determinants used in this study are organizational culture, involvement of a champion, change process, commitment, controls, and continuous education. Measures of ABC success and determinants were obtained using a survey of managers who have participated in ABC implementation in Canadian federal government organizations. The study found that the benefits derived from ABC implementation within Canadian public sector organizations do not measure up to the efforts invested, although respondents consider that some financial improvements have resulted from the implementations. Controls and culture proved to be the two variables that significantly relate to ABC success. The results could have implications for policymaking organizations such as the Treasury Board Secretariat of Canada and the Office of the Comptroller General (OCG). The latter should question the benefits of investments made in management accounting best practices in the federal government. The OCG could also direct departments and agencies to the right environment (success determinants) to be put in place in order to ensure the success of ABC initiatives. RÉSUMÉ Les auteurs évaluent le succès de la mise en ,uvre de la comptabilité par activités (CPA) au sein d'organismes du gouvernement fédéral du Canada selon cinq paramètres, soit l'utilisation et la fréquence d'utilisation de l'information produite par la CPA, les mesures décisionnelles prises, les améliorations financières, l'évaluation du succès global par la direction et une mesure composite regroupant ces quatre paramètres. Ils définissent ensuite les déterminants du succès de la CPA. Les déterminants utilisés dans la présente étude sont la culture organisationnelle, l'intervention d'un défenseur, le processus de changement, l'engagement, les contrôles et la formation continue. Les auteurs obtiennent les critères d'évaluation et les déterminants du succès de la CPA en procédant à un sondage auprès de cadres ayant participé à la mise en ,uvre de la CPA dans des organismes du gouvernement fédéral du Canada. Ils constatent que les avantages découlant de cet exercice au sein des organismes du secteur public canadien ne sont pas à la hauteur des efforts investis, même si les répondants estiment en avoir tiré certaines améliorations financières. Il semble que les variables des contrôles et de la culture soient celles qui se rattachent de façon significative au succès de la CPA. Les résultats de l'étude pourraient avoir des conséquences pour les organismes responsables de l'élaboration des politiques comme le Secrétariat du Conseil du Trésor du Canada et le Bureau du contrôleur général (BCG). Ce dernier devrait s'interroger sur ce que rapportent les sommes investies par le gouvernement fédéral dans les pratiques de comptabilité de management les meilleures. Le BCG pourrait également orienter les ministères et les organismes gouvernementaux vers l'environnement (ou les déterminants du succès) qu'il convient de mettre en place pour assurer la réussite des projets de CPA.

Individual variation in reproductive costs of reproduction: high-quality females always do better

JOURNAL OF ANIMAL ECOLOGY, Issue 1 2009
Sandra Hamel
Summary 1Although life-history theory predicts substantial costs of reproduction, individuals often show positive correlations among life-history traits, rather than trade-offs. The apparent absence of reproductive costs may result from heterogeneity in individual quality. 2Using detailed longitudinal data from three contrasted ungulate populations (mountain goats, Oreamnos americanus; bighorn sheep, Ovis canadensis; and roe deer, Capreolus capreolus), we assessed how individual quality affects the probability of detecting a cost of current reproduction on future reproduction for females. We used a composite measure of individual quality based on variations in longevity (all species), success in the last breeding opportunity before death (goats and sheep), adult mass (all species), and social rank (goats only). 3In all species, high-quality females consistently had a higher probability of reproduction, irrespective of previous reproductive status. In mountain goats, we detected a cost of reproduction only after accounting for differences in individual quality. Only low-quality female goats were less likely to reproduce following years of breeding than of nonbreeding. Offspring survival was lower in bighorn ewes following years of successful breeding than after years when no lamb was produced, but only for low-quality females, suggesting that a cost of reproduction only occurred for low-quality females. 4Because costs of reproduction differ among females, studies of life-history evolution must account for heterogeneity in individual quality.

Site reoccupation in fragmented landscapes: testing predictions of metapopulation theory

JOURNAL OF ANIMAL ECOLOGY, Issue 2 2001
Ralph S. Hames
Summary 1,Populations of formerly continuously distributed species subdivided by habitat fragmentation may show distributions in space and time that are consistent with predictions of metapopulation theory. Local extinctions and recolonizations should result in the most fragmented sites being infrequently occupied and the least fragmented sites being continuously occupied by sensitive species. The probability of extinction is predicted to be negatively correlated with patch size and the amount of habitat in the landscape. Conversely, recolonization is predicted to be negatively correlated with the isolation of the patch, and positively correlated with the amount of habitat in the landscape. 2,Data from a 3-year study of the effect of fragmentation were used to test whether these predictions from metapopulation theory apply to populations of the long-distance migrant forest bird Piranga olivacea (Scarlet Tanager) in fragmented North American landscapes. 3,Principal components analysis was used to derive a composite measure of fragmentation. This measure was used in a logistic regression as a predictor of the number of years that territorial males would occupy a site, given that it was occupied at least once. More fragmented sites were more likely to be occupied only once; the least fragmented sites were more likely to be occupied in all three years. Data on fragmentation were necessary, but not sufficient, to predict site reoccupation, and were poor predictors at medium levels of fragmentation. 4,The univariate measures of fragmentation (patch size and isolation, proportion of forest, and forest/non-forest edge), were also used in logistic regressions to predict the separate probabilities of local extinction or recolonization. Local extinctions were negatively correlated with patch size and amount of forest in the landscape, as predicted. Recolonizations were negatively correlated with isolation of the patch as predicted, and surprisingly, also with the amount of edge in the landscape. This suggests that stochasticity may drive extinctions, but that habitat selection may play an important role in recolonization. 5,Demographic data are usually required to establish the suitability of habitat to support persistent populations, but multiple-year distributional data can provide information on habitat quality far above that obtained from single-year studies.

Do Investors Really Value Corporate Governance?

JOURNAL OF INTERNATIONAL FINANCIAL MANAGEMENT & ACCOUNTING, Issue 2 2007
Evidence from the Hong Kong Market
To examine the relation between corporate governance and firm value, we develop an instrument to assess the corporate governance practices of listed companies in Hong Kong. Based on the Revised OECD Principles of Corporate Governance (OECD) and the Code of Best Practices (HKEx), we construct a corporate governance index (CGI) for Hong Kong listed companies. Unlike measures used in other studies, the CGI score reflects the presence of good corporate governance practices as well as variation in the quality of corporate governance practices. Empirical evidence shows that a company's market valuation is positively related to its overall CGI score, a composite measure of a firm's corporate governance practices. We also find that the transparency component of the CGI score drives the relation with market valuation. In summary, this study provides supporting evidence for the notion that, in Hong Kong, good corporate governance practices are consistent with value maximization. [source]


Endectocide residues affect insect attraction to dung from treated cattle: implications for toxicity tests

MEDICAL AND VETERINARY ENTOMOLOGY, Issue 4 2007
K. D. FLOATE
Abstract A 3-year study was performed in southern Alberta, Canada to assess the effect of endectocide residues on the attractiveness of cattle dung to colonizing insects. In 2003 and 2004, insect captures were compared between pitfall traps baited with dung of untreated cattle and paired traps baited with dung of cattle that had been treated 7 days previously with topically applied doramectin, eprinomectin, ivermectin or moxidectin. Faecal residues associated with each compound affected insect captures in both spring and autumn of each year. Effects were detected (P < 0.05) for a total of 94 cases representing 27 insect taxa from 13 families in three orders (Coleoptera, Diptera, Hymenoptera). Two-fold differences in captures were common. Up to six-fold differences were observed. Eleven cases of attraction and 11 cases of repellency were associated with residues of doramectin. Eprinomectin tended to repel insects, with decreased captures for 19 of 29 cases of effect. Ivermectin showed a strong attractive effect, with increased captures for 17 of 25 cases. Moxidectin also showed a strong attractive effect, with increased captures for 17 of 18 cases. Comparisons between compounds suggested that results for doramectin best predicted results for eprinomectin and vice versa. In 2005, insect captures were compared between pitfall traps baited with dung of untreated cattle and traps baited with dung from cattle treated 3, 7 or 14 days previously with topically applied doramectin. Effects were detected in 14 cases plus one case of near significance (P= 0.053). Significant differences between control vs. days 3, 7 and/or 14 dung were detected in nine cases. Residues enhanced captures in seven of these cases. Day 14 dung affected captures in six of these cases. This study shows that endectocide residues can affect the number of insects attracted to colonize and oviposit in dung. Hence, the emergence of their offspring from field-colonized dung of untreated vs. endectocide-treated cattle should not be used as a measure of residue toxicity per se, but rather as a measure of ,insect activity'. Insect activity is a composite measure of residue toxicity, the number and species composition of insect colonists, and the mortality factors (e.g. predation, parasitism, competition) associated with the co-occurrence of these species in the dung pat.

Development of the practice environment scale of the nursing work index,,

RESEARCH IN NURSING & HEALTH, Issue 3 2002
Eileen T. Lake
Abstract Five subscales were derived from the Nursing Work Index (NWI) to measure the hospital nursing practice environment, using 1985,1986 nurse data from 16 magnet hospitals. The NWI comprises organizational characteristics of the original magnet hospitals. The psychometric properties of the subscales and a composite measure were established. All measures were highly reliable at the nurse and hospital levels. Construct validity was supported by higher scores of nurses in magnet versus nonmagnet hospitals. Confirmatory analyses of contemporary data from 11,636 Pennsylvania nurses supported the subscales. The soundness of the new measures is supported by their theoretical and empirical foundations, conceptual integrity, psychometric strength, and generalizability. The measures could be used to study how the practice environment influences nurse and patient outcomes. © 2002 Wiley Periodicals, Inc. Res Nurs Health 25:176,188, 2002 [source]


Investigation of the Multidimensional Model of Job Insecurity in China and the USA

APPLIED PSYCHOLOGY, Issue 4 2006
Cynthia Lee
Il y a plus d'une décennie, Ashford, Lee, and Bobko (1989) ont développé un outil de mesure standard permettant évaluer des niveaux individuels d'insécurité au travail. Les années suivantes, des chercheurs se sont demandé si la totalité des mesures composant cet instrument était nécessaire. Nous avons donc examiné l'utilité des différentes dimensions du test multidimensionnel de l'Insécurité au travail de Ashford et al. (1989) aux Etats Unis et en Chine, en éprouvant et élargissant les conclusions antérieures. Nos résultats suggèrent qu'éliminer les dimensions "caractéristiques du travail" et "impuissance" de l'instrument multidimensionnel initial est prématuré dans les deux cultures. D'autres recherches s'avèrent donc nécessaires pour déterminer l'utilité de cet outil dans sa version complète. Les implications de nos résultats sont discutées. Over a decade ago, Ashford, Lee, and Bobko (1989) developed a standard measure for those interested in assessing levels of individual job insecurity. In ensuing years, some researchers have questioned whether the entire measure is necessary. We examined the usefulness of the components of Ashford et al.'s (1989) multidimensional measure of job insecurity in both the United States and China, as well as replicating and extending prior findings regarding antecedents and consequences. Our results suggest that the call to eliminate job features or powerlessness from the fully composite measure of job insecurity is premature in both cultures. We call for more research on the utility of the fully operationalised measure. Implications of our findings are discussed. [source]


Components of Relationship Quality in Chimpanzees

ETHOLOGY, Issue 9 2008
Orlaith N. Fraser
A novel approach to studying social relationships in captive adult chimpanzees (Pan troglodytes) was taken by using principal components analysis (PCA) to extract three key components of relationship quality from nine behavioural variables. Based on the loadings of the behavioural variables, the components appeared to match previously hypothesized critical aspects of social relationships and were therefore labelled Value, Compatibility and Security. The effects of kinship, sex combination, age difference and time spent together on each of the relationship quality components were analysed. As expected, kin were found to have more valuable, compatible and secure relationships than non-kin. Female,female dyads were found to be more compatible than male,male or mixed-sex dyads, whereas the latter were found to be most secure. Partners of a similar age were found to have more secure and more valuable relationships than those with a larger age gap. Individuals that were together in the group for longer were more valuable and more compatible, but their relationships were found to be less secure than individuals that were together in the group for a shorter time. Although some of the results may be unexpected based on chimpanzee socio-ecology, they fit well overall with the history and social dynamics of the study group. The methods used confer a significant advantage in producing quantitative composite measures of each component of relationship quality, obtained in an objective manner. These findings therefore promote the use of such measures in future studies requiring an assessment of the qualities of dyadic social relationships. [source]


Preparing a large data set for analysis: using the Minimum Data Set to study perineal dermatitis

JOURNAL OF ADVANCED NURSING, Issue 4 2005
Kay Savik MS
Aim., The aim of this paper is to present a practical example of preparing a large set of Minimum Data Set records for analysis, operationalizing Minimum Data Set items that defined risk factors for perineal dermatitis, our outcome variable. Background., Research with nursing home elders remains a vital need as ,baby boomers' age. Conducting research in nursing homes is a daunting task. The Minimum Data Set is a standardized instrument used to assess many aspects of a nursing home resident's functional capability. United States Federal Regulations require a Minimum Data Set assessment of all nursing home residents. These large data would be a useful resource for research studies, but need to be extensively refined for use in most statistical analyses. Although fairly comprehensive, the Minimum Data Set does not provide direct measures of all clinical outcomes and variables of interest. Method., Perineal dermatitis is not directly measured in the Minimum Data Set. Additional information from prescribers' (physician and nurse) orders was used to identify cases of perineal dermatitis. The following steps were followed to produce Minimum Data Set records appropriate for analysis: (1) identification of a subset of Minimum Data Set records specific to the research, (2) identification of perineal dermatitis cases from the prescribers' orders, (3) merging of the perineal dermatitis cases with the Minimum Data Set data set, (4) identification of Minimum Data Set items used to operationalize the variables in our model of perineal dermatitis, (5) determination of the appropriate way to aggregate individual Minimum Data Set items into composite measures of the variables, (6) refinement of these composites using item analysis and (7) assessment of the distribution of the composite variables and need for transformations to use in statistical analysis. Results., Cases of perineal dermatitis were successfully identified and composites were created that operationalized a model of perineal dermatitis. Conclusion., Following these steps resulted in a data set where data analysis could be pursued with confidence. Incorporating other sources of data, such as prescribers' orders, extends the usefulness of the Minimum Data Set for research use. [source]


Change in Motor Function and Risk of Mortality in Older Persons

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2007
Aron S. Buchman MD
OBJECTIVES: To assess the association between change in motor function and mortality. DESIGN: Prospective, observational cohort study. SETTING: Approximately 40 retirement communities across the Chicago metropolitan area participating in the Rush Memory and Aging Project. PARTICIPANTS: Eight hundred thirty-seven community-based older persons without dementia. MEASUREMENTS: Change in composite measures of motor performance and muscle strength. RESULTS: During a mean follow-up of 2.2 years, 81 persons died. In a proportional hazards model adjusted for age, sex, education, and body mass index, each 1-unit increase in the level of baseline motor performance was associated with an approximately 10% decrease in risk of mortality (hazard ratio (HR)=0.901, 95% confidence interval (CI)=0.863,0.941), and each unit of annual increase in motor performance was associated with an approximately 11% decrease in the risk of mortality (HR=0.887, 95% CI=0.835,0.942). In a similar model, each 1-unit increase in the level of baseline strength was associated with an approximately 9% decrease in the risk of mortality (HR=0.906, 95% CI=0.859,0.957), and each 1-unit annual increase in strength was associated with an approximately 10% decrease in the risk of mortality (HR=0.898, 95% CI=0.809,0.996). These results were similar when men and women were analyzed separately and after controlling for physical activity, cognition, and chronic disorders. When motor performance and muscle strength were examined in a single model, only baseline and annual change in motor performance were associated with mortality. CONCLUSION: Level and rate of change in strength and motor performance are associated with mortality. The attenuation of the association between strength and mortality by motor performance suggests that motor function is not a unitary process and that its components may vary in their associations with adverse health consequences in older persons.

The Changing External Exposure of Australian Industry

THE AUSTRALIAN ECONOMIC REVIEW, Issue 3 2005
Robyn Swift
This article examines changes in trade-related external exposure for Australian industry from 1990,91 to 2000,01, using primary and composite measures that capture the effects of exports, imports and imported inputs. The primary measures show that export market share for all exporting industries increased, but import market share increased at an equal or greater rate both overall and in most industries. Input value import shares also increased across virtually all industries. Two composite measures are calculated, the Index of Effective Exposure (IEE) and an extended IEE incorporating import market shares. The extended IEE shows that the net external exposure of Australian industry has been increasing over the decade, particularly in the Manufacturing and Mining Divisions. The net exposure of Australian manufacturing industries is lower than expected compared to the United States, Canada, the United Kingdom and Japan, but the rankings of manufacturing industries in each country are similar and becoming more so.
