    The Highland Stoneroller (Campostoma spadiceum) was described as a distinct species in 2010. Since then, the only study specific to this species is a survey of distribution, and nothing is known about reproduction. We examined 134 lots including 315 specimens of C. spadiceum housed in the Henderson State University collection of fishes to evaluate the timing of reproductive events. We dissected individuals to reveal sex and reproductive status. Females as small as 49 mm total length were able to yolk eggs, and follicles were in development by October. Ripe eggs were present in specimens collected from January through May, but were most common in March through May. Several females had oviposited in early March, but most specimens that appeared to have spawned had done so likely in April. Nuptial tubercles appeared on males as early as January and February, but most adult males were fully tubercled from March through May

    Information Diffusion in a Cobweb World

    Based on an assumption of one-way learning, Granato and Wong (2004) consider a framework with two groups of agents, Group L and Group H, where Group L is less attentive and uses the expectations of the more or highly attentive Group H to update their forecasts. The paper shows the boomerang effect, which is defined as a situation where the inaccurate forecasts of a less attentive group confound a more attentive group\u27s forecasts. This extended paper relaxes the one-way learning assumption and investigates the case that both groups are learning from each other, i.e., dual learning. Simulations suggest that a boomerang effect still exists. Surprisingly, although the highly attentive group has a full set of information to make forecasts, they still learn from Group L. The reason is that Group H adjusts their forecasts because there is available information in Group L\u27s forecast measurement error

    Inward FDI, Remittances, and Out-migration

    In this study, we look at the relationship between remittances received at home, inward Foreign Direct Investment (FDI) and out-migration of individuals with different levels of education. Using the bilateral international migration data in 1990 and 2000, we find that inward FDI tends to deter the out-migration of individuals with secondary and tertiary education, but has no significant impact on the out-migration of individuals with primary education. In addition, remittances received at home induce the out-migration of individuals with primary education, but not the out-migration of individuals with secondary and tertiary education. The stock of existing migrants in a foreign country encourage future out-migration regardless of migrants’ levels of education

    Sustainable Development and the Philippine Fisheries Code: A Critique

    Analysis of the Philippine Fisheries Code results to the findings that some provisions promote sustainable development while others are contentious. The good provisions can then be implemented while the deficient provisions should be subjected to a thorough study.fisheries sector

    Feasibility, Acceptability, and Preliminary Outcomes of a Culturally Adapted Evidence-Based Treatment for Latino Youth With ADHD

    Objective: To advance our knowledge about the most effective way to treat Latino youth with ADHD, the current feasibility and pilot study compared a culturally adapted evidence-based treatment (CAT) for ADHD to standard evidence-based treatment (EBT). Method: Following a comprehensive ADHD assessment, 61 Latino families of school-aged children (mean age of 8 years) were randomly assigned to either CAT or standard EBT (i.e., parent management training). Results: CAT outperformed standard EBT when examining homework completion and mother-reported treatment satisfaction. Apart from two trends favoring CAT, CAT and EBT both resulted in significant improvements in parent- and teacher-reported ADHD symptoms and functional impairment, as well as mother- and father-reported parental functioning. Conclusion: CAT outperformed standard EBT when examining several engagement and acceptability outcomes. CAT and EBT were equally effective when examining traditional treatment outcomes, which is impressive considering the robustness of standard EBT, especially when delivered by culturally competent staff

    Incremental Clinical Utility of ADHD Assessment Measures With Latino Families

    Get PDF
    Objective: This study examined the incremental clinical utility of parent and teacher reports of ADHD symptomatology and functional impairment in Latino youth, as well as parent and teacher agreement with the final clinical judgment on a diagnostic structured interview. Method: Participants included 70 Latino youth (47 males, 23 females; M age = 8.13 years, SD = 2.51 years) and their parents and teachers; 60 participants were diagnosed with ADHD. Correlations, percent agreement, kappas, and regressions were utilized. Results: Results demonstrated that teachers agreed with the final clinical judgment more often than did parents. Results additionally demonstrated that functional impairment did not statistically significantly improve diagnostic models already including ADHD symptoms; follow-up analyses were run and are discussed. Finally, results demonstrated that teacher reports statistically significantly improved diagnostic models already including parent reports. Conclusion: The current findings suggest the importance of including both parent and teacher reports of both ADHD symptomatology and functional impairment when assessing ADHD in Latino youth
