Promoting use of farmers’ markets (FMs) is a promising community‐level strategy to increase access to nutritious foods such as fruits and vegetables. Yet, FM shopping among people with Supplemental Nutrition Assistance Program (SNAP) benefits remains low. This research examined predictors of FM shopping among SNAP recipients living within 1 mile of a FM. A cross‐sectional survey of SNAP participants (N = 270) was conducted in 2015 in Cleveland and East Cleveland, OH, USA. Multinomial regression and zero‐truncated Poisson regression analyses were conducted to examine factors associated with FM shopping. Results indicate 48% reported shopping at a FM at least once in the past year, 26% had shopped at a FM before, but not in the last year, and 26% had never shopped at a FM. The multivariable analyses found awareness of FMs and a healthy food incentive program, and four dimensions of healthy food access are significantly associated with FM shopping among SNAP recipients. The food access dimensions included service delivery, spatial‐temporal, personal, and social access. Findings highlight modifiable leverage points for improving the reach of FMs among low‐income populations.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) is associated with disruptionsin reward sensitivity and regulatory processes. However, it is unclear whether thesedisruptions are better explained by comorbid disruptive behavior disorder (DBD)symptomology. This study sought to examine this question using multiple levels ofanalysis (i.e., behavior, autonomic reactivity). One hundred seventeen children (aged 6 to 12 years; 72.6% male; 69 with ADHD) completed theBalloon-Analogue Risk Task (BART) to assess external reward sensitivity behaviorally.Sympathetic-based internal reward sensitivity and parasympathetic-based regulationwere indexed via cardiac pre-ejection period (PEP) and respiratory sinus arrhythmia(RSA), respectively. Children with ADHD exhibited reduced internal reward sensitivity (i.e.,lengthened PEP; F(1,112)=4.01, p=0.047) compared to healthy controls and werecharacterized by greater parasympathetic-based dysregulation (i.e., reduced RSAaugmentation F(1,112)=10.12, p=0.002). However, follow-up analyses indicated theADHD effect was better accounted for by comorbid DBD diagnoses; that is, childrenwith ADHD and comorbid ODD were characterized by reduced internal rewardsensitivity (i.e., lengthened PEP; t=2.47, p=0.046) and by parasympathetic-baseddysregulation (i.e., reduced RSA augmentation; t=3.51, p=0.002) in response to rewardwhen compared to typically developing youth. Furthermore, children with ADHD and comorbid CD exhibited greater behaviorally-based external reward sensitivity (i.e.,more total pops; F(3,110)= 5.96, p=0.001) compared to children with ADHD only (t=3.87, p=0.001) and children with ADHD and ODD (t=3.56, p=0.003). Results suggest that disruptions in sensitivity to reward may be betteraccounted for, in part, by comorbid DBD.Key Words: attention-deficit/hyperactivity disorder, autonomic nervous system,disruptive behavior disorders, reward sensitivityPowered  相似文献

In order to acquire language, infants must extract its building blocks—words—and master the rules governing their legal combinations from speech. These two problems are not independent, however: words also have internal structure. Thus, infants must extract two kinds of information from the same speech input. They must find the actual words of their language. Furthermore, they must identify its possible words, that is, the sequences of sounds that, being morphologically well formed, could be words. Here, we show that infants’ sensitivity to possible words appears to be more primitive and fundamental than their ability to find actual words. We expose 12- and 18-month-old infants to an artificial language containing a conflict between statistically coherent and structurally coherent items. We show that 18-month-olds can extract possible words when the familiarization stream contains marks of segmentation, but cannot do so when the stream is continuous. Yet, they can find actual words from a continuous stream by computing statistical relationships among syllables. By contrast, 12-month-olds can find possible words when familiarized with a segmented stream, but seem unable to extract statistically coherent items from a continuous stream that contains minimal conflicts between statistical and structural information. These results suggest that sensitivity to word structure is in place earlier than the ability to analyze distributional information. The ability to compute nontrivial statistical relationships becomes fully effective relatively late in development, when infants have already acquired a considerable amount of linguistic knowledge. Thus, mechanisms for structure extraction that do not rely on extensive sampling of the input are likely to have a much larger role in language acquisition than general-purpose statistical abilities.  相似文献

This paper explains the concept of di-egophrenia and contrasts the dynamics of and treatment approach for di-egophrenics with those advocated for borderlines. The essential difference between the two is that the former functions with an introjected parental pseudo-ego and a submerged ego, while the latter suffers from a split ego. Ambivalence is described as the central feature of the di-egophrenic. Treatment of the di-egopltrenic is then detailed, with psychoanalysis in groups recommended as a treatment adjunct of particular value along with the alternate session. An experimental group solely composed of di-egophrenics is described and outcomes for members of this group are discussed.  相似文献

The aim of this study was to determine whether characteristics of leadership identified among adults also exist among young gifted children. The study was conducted in Israel among 63 gifted children aged 10 to 14 who completed the Leadership Questionnaire, constructed especially for this study. The characteristics found to distinguish between high and low scorers on leadership were responsibility, desire to dominate, consistency, physical energy, achievement orientation, expressive and persuasive powers, cooperation, adaptability, daring, self-confidence, and emotional equilibrium. The results confirmed our hypothesis that the characteristics of leadership identified in adults do exist among gifted children.  相似文献

Two studies examined when and why people experience disappointment for others. Study 1 demonstrated that participants reported disappointment for another's outcome only when the outcome had strong personal implications. Study 2 demonstrated that self-image concerns rather than empathy or resource concerns mediated the experience of disappointment for others. Collectively, these findings suggest that people experience disappointment for others when those outcomes implicate the self-image.  相似文献

This analysis evaluated the efficacy of a variety of recruitment methods employed in a medication trial in a veteran population. Recruitment and demographic data were collected over the course of a randomized controlled trial (RCT) assessing the efficacy of an experimental medication for posttraumatic stress disorder (PTSD). Multivariate logistic regression was used to identify demographic and recruitment variables predictive of consenting to participation in the trial. Data were collected for 1,050 potential study participants. As compared with individuals contacted by mail based on chart review, potential participants who were referred by a clinician were 3 times more likely to consent to participate, and individuals who responded to an advertisement were 5 times more likely to consent to participate. Females were more likely to respond to advertisements, whereas males were more likely to be referred. Those who were referred were significantly older than potential participants identified via the directed mailing. Clinician referral was the method most likely to lead to identifying an eligible and willing participant. When designing a recruitment plan for a clinical trial, factors such as the target sample and available staff should be carefully considered.  相似文献

Compulsive sexual behavior (CSB) is defined as difficulties in controlling inappropriate or excessive sexual fantasies, urges, or behaviors that cause subjective distress or impairment in important areas of daily functioning. Using data from a baseline telephone interview, we examined the prevalence of CSB in a convenience sample of 820 postdeployed U.S. military male and female veterans and investigated correlates of CSB with sociodemographics and other mental health and sexual history characteristics. More men (13.8%) than women (4.3%) endorsed CSB-related symptoms. Given the limited sample size of women reporting CSB, correlational analyses were conducted only with men. After adjusting for significant sociodemographics, results indicated that gambling, suicidality, and sexually transmitted infections were significantly associated with male CSB. Current results suggest that CSB may be prevalent among U.S. military veterans post deployment and associated with significant negative health indices in men. CSB warrants attention regarding screening and intervention.  相似文献

Perceptual fluctuations experienced during motion-induced blindness (MIB) have been characterized as the result of a competition between representations of the moving mask and stationary (or slowly moving) targets (Bonneh, Cooperman, & Sagi, 2001). While there is evidence to support a local influence of the mask on target disappearance, what is not yet clear is whether the global properties of the mask can likewise impact disappearance. In the present study, we investigated the presence of a global effect of the mask on MIB by manipulating global motion properties of the mask while controlling its local motion properties surrounding the target. Results showed a significant impact of the global mask properties on the observed degree of disappearance. We also tested for a complementary local effect by comparing conditions in which we manipulated local mask properties while controlling global properties. This analysis did not yield evidence for a local effect, although this may have been due to our weaker manipulation of local mask properties compared to previous studies. Overall, the present results highlight a key role of global stimulus representations in producing the perceptual disappearances observed in MIB.  相似文献
