    Since the fall of the Bretton Woods agreement and the rise of a floating exchange rate regime there has been a marked increase in the volatility of exchange rates. The movement of exchange rates relative to other currencies, or exchange rate variability, is seen as a risk by importers and exporters. The uncertainty surrounding exchange rate movements affects importers and exporters who must determine domestic prices of traded goods without knowing how the exchange rate will move between the time an order is placed and the time payment is due. Theory supports that as exchange rate variability increases, international trade will fd, ceterisparibu

    Changes in fruit and vegetable consumption in relation to changes in sleep characteristics over a 3-month period among young adults

    OBJECTIVE: To evaluate whether increases in fruit and vegetable (FV) consumption were associated with concomitant changes in insomnia symptoms, sleep duration, and quality. DESIGN: Secondary longitudinal analysis of a randomized trial, baseline to 3 months. SETTING: Integrated health care systems in Detroit, Michigan and Danville, Pennsylvania. PARTICIPANTS: About 1165 young adults who were low consumers of FV (/day) at baseline. INTERVENTION: Online 3-arm program designed to increase FV consumption. MEASUREMENTS: We categorized FV changes into 4 categories: no change or decrease, 1 serving increase, 2 serving increase, and 3 or more serving increase. We then compared the changes in chronic insomnia classification (yes or no), sleep duration, quality, and time to fall asleep (all self-reported) across the FV change categories. Analyses were both overall and stratified by gender, adjusting for potential confounders (depression, physical activity, education, children, and study site). RESULTS: Average age ± SD was 26 ± 2.8 years (71% women). At 3-month follow-up, participants on average increased FV intake by 1.2 ± 1.4 servings. Women who increased FV intake by 3+ servings showed improvements in insomnia symptoms (2-fold higher odds of improvement; 95% CI 1.1 to 3.6), sleep quality (0.2-point higher sleep quality score; 95% CI -0.01, 0.3), and time to fall asleep (4.2 minutes; 95% CI -8, 0) compared to women who did not change or decreased their FV intake. Associations were not as apparent among men. CONCLUSION: Young women with low consumption of FV may experience improvements in insomnia-related sleep difficulties by increasing their consumption of FV

    Mott transition in the π\pi-flux SU(44) Hubbard model on a square lattice

    We employ the projector quantum Monte Carlo simulations to study the ground-state properties of the square-lattice SU(4) Hubbard model with a π\pi flux per plaquette. In the weak coupling regime, its ground state is in the gapless Dirac semi-metal phase. With increasing repulsive interaction, we show that, a Mott transition occurs from the semimetal to the valence bond solid, accompanied by the Z4Z_4 discrete symmetry breaking. Our simulations demonstrate the existence of a second-order phase transition, which confirms the Ginzburg-Landau analysis. The phase transition point and the critical exponent η\eta are also estimated. To account for the effect of a π\pi flux on the ordering in the strong coupling regime, we analytically derive by the perturbation theory the ring-exchange term which describes the leading-order difference between the π\pi-flux and zero-flux SU(4) Hubbard models.Comment: 8 pages, 9 figure

    Community health workers as change agents in improving equity in birth outcomes in Detroit

    We examined whether pairing pregnant women with community health workers improved pregnancy outcomes among 254 Black women with singleton pregnancies participating in the Women-Inspired Neighborhood (WIN) Network: Detroit using a case-control design. A subset (N = 63) of women were recontacted and asked about program satisfaction, opportunities, and health behaviors. Michigan Vital Statistics records were used to ascertain controls (N = 12,030) and pregnancy and infant health outcomes. Logistic and linear regression were used to examine the association between WIN Network participation and pregnancy and infant health outcomes. The WIN Network participants were less likely than controls to be admitted to the neonatal intensive care unit (odds ratio = 0.55, 95% CI 0.33-0.93) and had a longer gestational length (mean difference = 0.42, 95% CI 0.02-0.81). Community health workers also shaped participants\u27 view of opportunities to thrive. This study demonstrates that community health workers can improve pregnancy outcomes for Black women

    Teen, Parent, and Clinician Expectations About Obesity and Related Conditions During the Annual Well-Child Visit

    Purpose: This study aimed to examine family (patient, parent/guardian) and clinician preferences for identification and management of obesity and obesity-related conditions during the well-child visit. Methods: Four focus groups with teen patients (n = 16), four focus groups with parents (n = 15) and one focus group with providers (n = 12) were conducted using a structured moderator guide tailored to each population. Eligible patients had a well-child visit during the past 12 months and a diagnosis of overweight, obesity, hyperlipidemia or elevated blood pressure. Parents who attended their child’s well-child visit and whose child met the diagnostic criteria were eligible. Teen focus groups were divided by gender (male/female) and age (14–15/16–17 years). Focus group transcripts were coded for concepts and themes using qualitative data and thematic analysis. Analysis was performed across groups to determine common themes and domains of intersect. Results: Teens and parents expect weight to be discussed at well-child visits and prefer discussions to come from a trusted clinician who uses serious, consistent language. Teens did not recognize the health implications from excess weight, and both parents and teens express the need for more information on strategies to change behavior. Providers recognize several challenges and barriers to discussing weight management in the well-child visit. Conclusions: A clinician-teen-family relationship built on trust, longevity, teamwork, support and encouragement can create a positive atmosphere and may improve understanding for weight-related messages for teens and families during a well-child visit
