This study examined the relationship of perceived neighborhood environment factors with recommended volume and intensity of walking in recreational senior walkers. A sample of 85 seniors used an accelerometer and completed the ALPHA questionnaire. Binomial logistic regressions were conducted to detect associations. Perceptions about traffic safety (odds ratio [OR] = 4.395; 95% confidence interval [CI] = 1.024; 18.866) and pleasant environment (OR = 8.718; 95% CI = 1.803; 42.149) were positively related with the achievement of 10,000 steps per day, in older women. The perception of nearby parks was positively associated with the compliance with peak 30-minutes cadence above 100, in older men (OR = 14.353; CI 95% = 1.321; 15.591). No more significant associations were found between perceptions of the neighborhood environment and walking at recommended intensity and volume levels. These results indicated that community initiatives that encourage traffic safety, pleasant environment, and parks may be a promising direction to promote walking at recommended volume and intensity in senior walkers. 相似文献

The two-sided power (TSP) distribution is a flexible two-parameter distribution having uniform, power function and triangular as sub-distributions, and it is a reasonable alternative to beta distribution in some cases. In this work, we introduce the TSP-binomial model which is defined as a mixture of binomial distributions, with the binomial parameter p having a TSP distribution. We study its distributional properties and demonstrate its use on some data. It is shown that the newly defined model is a useful candidate for overdispersed binomial data. 相似文献

Despite decades of policy aimed at the maintenance of Francophone communities in Ontario, the proportion of individuals with French as a mother tongue or who speak French most often at home has steadily declined. Research on language retention has highlighted the importance of sociodemographic and structural factors in understanding minority language practices. However, given the relationship between culture and action, this paper examines how cultural factors contribute to Franco‐Ontarians’ linguistic practices. Results indicate that beyond couple composition and the concentration of minority‐language speakers, cultural factors including identity, cultural consumption, and values play an instrumental role in Franco‐Ontarians’ linguistic continuity. The importance of considering linguistic continuity as part of a “package” of cultural practices is discussed. 相似文献

Recent studies have suggested that a relationship could exist between 25-hydroxyvitamin D [25(OH)D] deficiency and erectile dysfunction (ED). The present study evaluated the relationship between 25(OH)D levels and ED in male patients with type 2 diabetes mellitus (DM). The study included 98 patients with type 2?DM aged between 18–80 years. The International Index of Erectile Function (IIEF-5) Questionnaire was administered. The patients were divided into three groups according to IIEF-5 scoring: IIEF-5 score between 5–10, severe ED; IIEF-5 score between 11–20, moderate ED; IIEF-5 score between 21–25, no ED. Biochemical parameters, 25(OH)D and hormonal analysis tests were obtained in all patients. All parameters were compared between these three groups. Of 98 patients included in the study, 32 had severe ED, 45 had moderate ED and 21 had no ED. The mean age was 55.12?±?9.39 years and the mean 25(OH)D level was 13.69?±?8.15?ng/ml. When the three groups were compared, 25(OH)D levels were significantly lower in patients with the IIEF-5 score between 5–10 (p?=?0.020). There was a moderate positive relationship between IIEF-5 score and 25(OH)D level (r?=?0.21, p?=?0.038). The patients with severe ED have considerably lower 25(OH)D levels. 相似文献

Correcting household survey distribution data for missing income or for undersampling may give an idea of the extent of possible biases in measuring inequality, especially when there are reasons to expect the missing income and people to belong to the top of the distribution. There are simple ways to do so when only an aggregate estimate of how much is missing is available. Atkinson had provided a formula to correct the Gini coefficient for the missing income, which was later generalized by Alvaredo (Econ. Lett. 110(3), 274–277 2011). This paper concentrates on the whole distribution and explores various alternative adjustment methods based on three key parameters: how much income, how many people are missing and on what range of income the correction should bear. 相似文献

The purpose of this 5-year longitudinal study is to identify trajectories of team and individual sports participation in childhood, and to compare these trajectories on different types of internalizing problems. Parents reported their children's annual sports participation from the ages of 6–10 (n = 785) and teachers reported internalizing problems (depression, anxiety, social withdrawal) at the beginning and at the end of this period. The study used latent class growth analyses to identify two trajectories of team sports and two trajectories of individual sports participation were identified: (1) high participation, and (2) low participation. Considering baseline level of internalizing problems and gender, children in the high participation team sports trajectory show significantly fewer depression, anxiety, and social withdrawal behaviors at age 10 than those in the low participation team sports trajectory. No differences between individual sports trajectories were observed. Comparison with joint trajectory groups partially confirmed these results but also showed that sustained participation in multiple individual sports could also be linked to decreased anxiety. Our findings suggest that participation in team sports should be encouraged to promote certain aspects of children's mental health. 相似文献

Parents can actively seek knowledge (solicitation) or receive information provided willingly by the child (disclosure). In adolescence, disclosure is the main source of parental knowledge, but its importance may take root earlier in the course of development. We examined: 1) the factor structure of an instrument adapted for middle childhood measuring maternal perception of knowledge, solicitation, and children's self-disclosure; 2) changes in these dimensions over middle childhood; and 3) the respective contribution of solicitation and disclosure to parental knowledge. The mothers of 793 elementary school students (61.5% boys, 80.2% Canadian-born) completed a questionnaire annually from Grades 1 to 4. Multilevel confirmatory factor analysis confirmed the instrument's structure at all time points. Growth curve analyses showed that mothers’ perception of knowledge slightly declined from Grades 1 to 4. With respect to mothers’ perceived parental solicitation and child disclosure, gender interactions emerged. Solicitation declined for girls but remained stable for boys, while disclosure declined for girls but increased for boys over time. In addition, mothers' perception ofdisclosure and solicitation are both main sources of maternal knowledge regardless of age and gender in middle childhood. 相似文献

In this paper is remarked that “mixed” strategies in games of electoral competition do not need to be interpreted as random
moves. There are two a priori symmetric parties, and a finite (non spatial) set of alternatives. Parties are allowed to take
unclear positions, by campaining on a “platform” that is a mix of several alternatives. Each individual nevertheless identifies
a party with a single alternative, the number of individuals who identify a party with a given alternative being proportional
to the importance of that alternative in the party’s platform.

We develop a theory of representation of interdependent preferences that reflect the widely acknowledged phenomenon of keeping up with the Joneses (i.e. of those preferences which maintain that well-being depend on “relative standing” in the society as well as on material
consumption). The principal ingredient of our analysis is the assumption that individuals desire to occupy a (subjectively)
better position than their peers. This is quite a primitive starting point in that it does not give any reference to what
is actually regarded as “status” in the society. We call this basic postulate negative interdependence, and study its implications. In particular, combining this assumption with some other basic postulates that are widely used
in a number of other branches of the theory of individual choice, we axiomatize the relative income hypothesis, and obtain
an operational representation of interdependent preferences.
