Women's agricultural production is modeled as a sequential switching regression process determined by men's clearing labor capacity and women's harvest labor capacity. Results show that output was more often constrained by husband's clearing labor. However, men's economic contribution to household consumption is inversely related to women's agricultural output.

This paper has examined Pareto efficiency of household resources allocation and the appropriateness to use gender-specific models rather than unitary model while investigating economic performance of men and women managers of separate plots within horticultural households in Senegal, West Africa. This paper contributes to the gender and economics literature providing empirical evidence of intrahousehold resources allocation in a specific social, economic and cultural context in which polygamy occurs and where husband and wives manage separately their plots. The findings confirm the suitability of gender-specific models to shed light on the gender differential of performance. As the subject matter is efficiency, as well in econometric as in economic point...

Why Do Migrants Remit?: An Analysis for the Dominican Sierra

de la Briere, Benedicte; de Janvry, Alain; Lambert, Sylvie; Sadoulet, Elisabeth.

Two contrasting hypotheses about what motivates Dominican migrants to send remittances to their rural parents in the Sierra are tested: (1) an investment in potential bequests and (2) an insurance contract between parents and migrant children. Remittances from young migrants, males, and migrants who want to return to the Sierra follow a pattern consistent with investment. In contrast, female migrants with no intention of returning to the Sierra play the role of insurers. The gender composition of the migrant siblings affects this remittance task-sharing, since women with no remitting brothers show interest in inheritance, while men with no sisters offer insurance.

This paper examines fifteen cases of collective action in six villages in rural Bangladesh. Collective action was defined broadly and identified from significant episodes in previous life-history research in the same villages. The types of collective action identified were catalyzed by marriage; dowry and domestic violence; disputes over land; illness, injury and death in accidents; and theft and cheating. The role of development NGOs was less significant than would be expected considering their visibility in rural Bangladesh. The study suggests that ‘everyday forms’ (Scott 1985) of collective action often occur spontaneously and informally, with significant impact on peoples’ wellbeing, but with ambiguous outcomes for some poor people involved. This is a...

ABSTRACT The aim of this study was to determine slaughter and carcass traits of geese with different feather colour and gender. The study was conducted with Turkish geese in free-range production conditions in Kars, Turkey. A total of 282 geese (251 females, 31 males) were grouped by feather colour as black (n=49), white (n=77), black pied (n=127), and brown and brown tawny (n=29). Geese were weighed before slaughter and then the slaughter and carcass traits were determined. Data were subjected to one-way ANOVA, and post-hoc Tukey HSD test was applied to compare feather-colour means and the independent sample t-test was used to compare gender means. Feather colour did not influence (p>0.05) slaughter and carcass traits, except for hot carcass, feather...

ABSTRACT The experiment used 100 grey partridges (Perdix perdix L.), which were reared first in confinement and later in aviaries. Partridges were lighter and had greater body dimensions at 36 weeks compared to 12 weeks except for trunk length. Older birds showed greater values (p>0.05) of compactness and lower values of massiveness and long-leggedness. Significant differences were found for keel length in females. At 36 weeks, male and female partridges had significantly greater total intestinal length, males had significantly longer small intestine and rectum, and females were characterized by significantly longer caeca and greater (p<0.05) intestine to body length ratio. Older birds had significantly greater gizzard weight and percentage and heart...

The knowledge of consumer perception of meat tenderness and taste is essential to forecast a Brazilian quality value-based beef market. This study aimed to verify perception of tender (WBSF < 4.1 kg) from tough (> 4.8 kg) strip loin steak or uncharacteristic (calcium-treated/Ca-IM) and normal (non-calcium/NO-Ca) meat taste by consumers according to gender, age, education and income levels. Steaks were previously classified by shear force measurements as tender or tough. Each consumer was served a paired sample of one tender and of one tough steak, which were either Ca-IM or NO-Ca treated before tenderness classification. Three hundred and eight consumers answered a nine-point intensity (tenderness) and hedonic (taste) scales evaluation questionnaire....

Several ecological, genetic, and environmental factors are known to influence tannin concentration in plant tissues. In this study, the effects of seasonality, water availability, and sex of the plant on tannin concentration in the dioecious shrub Baccharis dracunculifolia were assessed. The effects of water availability on plant shoot growth and its relationship to tannin concentration were also experimentally evaluated. Tannins occurred in B. dracunculifolia from November to May, peaking during the summer (December to March). However, no relationship between tannin concentration, rainfall and temperature was found. No difference in tannin concentration and shoot growth was found between plants in the irrigated and control treatments, this suggesting that...

Curare, a selective skeletal muscle relaxant, has been used clinically to reduce shivering and as an anesthetic auxiliary in abdominal surgery. It is also widely used in animal experiments to block neuromuscular junction activity. Effective doses of curare diminish muscle contraction without affecting brain function, but at higher doses it is known to be lethal. However, the exact dose of curare initiating muscle relaxation vs. lethal effect has not been fully characterized in mice. In this study we carefully examined the dose-response for achieving muscle inactivity over lethality in both male and female mice (C57BL6/J). The most striking finding of this study is that female mice were highly susceptible to curare; both the EDm and LDm were at least 3-fold...

Gender differences in vascular expression of endothelin and ET A/ET B receptors, but not in calcium handling mechanisms, in deoxycorticosterone acetate-salt hypertension

David,F.L.; Montezano,A.C.I.; Rebouças,N.A.; Nigro,D.; Fortes,Z.B.; Carvalho,M.H.C.; Tostes,R.C.A..

We determined if the increased vascular responsiveness to endothelin-1 (ET-1) observed in male, but not in female, DOCA-salt rats is associated with differential vascular mRNA expression of ET-1 and/or ET A/ET B receptors or with functional differences in Ca2+ handling mechanisms by vascular myocytes. Uninephrectomized male and female Wistar rats received DOCA and drinking water containing NaCl/KCl. Control rats received vehicle and tap water. Blood pressure and contractile responses of endothelium-denuded aortic rings to agents which induce Ca2+ influx and/or its release from internal stores were measured using standard procedures. Expression of mRNA for ET-1 and ET A/ET B receptors was evaluated by RT-PCR after isolation of total cell RNA from both aorta...

Organic solvent exposure and contrast sensitivity: comparing men and women

Araki,L.M.; Nogueira,A.A.R.; Mansur,A.P..

The creatine kinase-isoenzyme MB (CK-MB) mass assay is one of the laboratory tests used for the diagnosis of myocardial infarction. It is recommended, however, that reference limits should take gender and race into account. In the present study, we analyzed the plasma CK-MB mass and troponin levels of 244 healthy volunteers without a personal history of coronary artery disease and with no chronic diseases, muscular trauma or hypothyroidism, and not taking statins. The tests were performed with commercial kits, CK-MB mass turbo kit and Troponin I turbo kit, using the Immulite 1000 analyzer from Siemens Healthcare Diagnostic. The values were separated according to gender and showed significant differences by the Mann-Whitney test. Mean (± SD) CK-MB mass...

The goal of this study was to compare the visual contrast sensitivity (CS) of men and women exposed and not exposed to organic solvents. Forty-six volunteers of both genders aged between 18 and 41 years (mean±SD=27.72±6.28) participated. Gas station attendants were exposed to gas containing 46.30 ppm of solvents at a temperature of 304±274.39 K, humidity of 62.25±7.59% and ventilation of 0.69±0.46 m/s (a passive gas chromatography-based sampling method was used considering the microclimate variables). Visual CS was measured via the psychophysical method of two-alternative forced choice using vertical sinusoidal gratings with spatial frequencies of 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, and 16.0 cpd (cycles per degree) and an average luminance of 34.4 cd/m2.

Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP), are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116) were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization) and if...

Chronotype is an established concept designed to identify distinct phase relationships between the expression of circadian rhythms and external synchronizers in humans. Although it has been widely accepted that chronotype is subjected to ontogenetic modulation, there is no consensus on the interaction between age and gender. This study aimed to determine the relationship between age- and gender-related changes in the morningness-eveningness character in a large sample of people. A total of 14,650 volunteers were asked to complete the Brazilian version of the Horne and Östberg chronotype questionnaire. The data demonstrated that, on average, women were more morning-oriented than men until the age of 30 and there were no significant differences between men...

Thyroid diseases are common, and use of levothyroxine is increasing worldwide. We investigated the influence of gender, race and socioeconomic status on the diagnosis and treatment of thyroid disorders using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of civil servants (35-74 years of age) from six Brazilian cities. Diagnosis of thyroid dysfunction was by thyrotropin (TSH), and free thyroxine (FT4) if TSH was altered, and the use of specific medications. Multivariate logistic regression models were constructed using overt hyperthyroidism/hypothyroidism and levothyroxine use as dependent variables and sociodemographic characteristics as independent variables. The frequencies of overt hyper- and...

During adolescence, the sleep phase delay associated with early school times increases daytime sleepiness and reduces psychomotor performance. Some studies have shown an effect of gender on psychomotor performance in adults and children. Males present faster reaction times (RT) compared with females. The aim of the present study was to evaluate the influence of gender on Palm psychomotor vigilance task (PVT) performance in adolescents. Thirty-four adolescents (19 girls, 13 to 16 years old) attending morning school classes of a public school in Curitiba, PR, Brazil, participated in the study. Sleep patterns were measured using actigraphy and sleepiness data were accessed with the Karolinska Sleepiness Scale (KSS). KSS and PVT measurements were collected at...

It has been suggested that there are no gender effects on esophageal motility. However, in previous studies the subjects did not perform multiple swallows and the quantitative features of esophageal contractions were not evaluated. In order to investigate the gender effects on esophageal motility we studied 40 healthy normal volunteers, 20 men aged 37 ± 15 years (mean ± SD), and 20 women aged 38 ± 14 years. We used the manometric method with an eight-lumen polyvinyl catheter and continuous perfusion. The upper and lower esophageal sphincter pressures were measured by the rapid pull-through method. With the catheter positioned with one lumen opening in the lower esophageal sphincter, and the others at 5, 10 and 15 cm above the sphincter, ten swallows of a...

The present study was conducted to obtain reference values for brachial-ankle pulse wave velocity (baPWV) and to evaluate influencing factors of baPWV according to gender. Using automatic devices, baPWV was measured simultaneously in 2095 subjects. A total of 647 healthy subjects, none of whom presented atherosclerotic risk factors, were analyzed in the present study. Two different statistical methods were used to obtain reference values for baPWV according to subject gender and age. The association between baPWV value and gender, as well as other features, were analyzed. For male subjects, multiple stepwise analysis showed that age, systolic blood pressure (SBP), heart rate (HR), and plasma levels of triglycerides (TG) were independent predictors of...
