Advancing Our Knowledge of ADHD in Latino Children: Psychometric and Cultural Properties of Spanish-Versions of Parental/Family Functioning Measures

The lack of available Spanish versions of assessment measures contributes to insufficient research and underutilization of mental health services for Latino children with Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, the goal of the current study was to examine the psychometric and cultural properties of several Spanish versions of parental/family functioning measures commonly used in comprehensive ADHD assessments (i.e., the Parenting Sense of Competence Scale, Alabama Parenting Questionnaire, and Confusion, Hubbub, and Order Scale). Participants included 68 Spanish-speaking, Latino parents in Southeast Wisconsin. In general, the Spanish translations of the measures demonstrated good reliability and validity. Furthermore, the psychometrically-sound measures were significantly related to acculturation as predicted, suggesting that the scales are not only psychometrically valid, but also culturally valid for use with Spanish-speaking, Latino families

Spring Forage Stash Module to Prevent Forage Crisis on Uruguayan Livestock Systems: An Evaluation Based on Model Simulations

In Uruguay, rangeland cattle production systems support national economy by beef exportation chain and economic inputs to the country. Soil hydric stress episodes results to forage crisis on grassland-based production systems, having high impact on its trajectory and leaving sequels at several farm levels mainly on rearing cattle systems in drought sensitive regions of the country. In that context, the proposal is to create a spring forage stash module, with a simple management rules as a mechanism to build stability to farms and to buffering drought impact. The concept is to differ spring forage (season with low variation coefficient on net primary production) to summer (season with high variation and susceptible to drought stress episodes). This forage stash module is actually started to be implemented in some monitored farms nevertheless, the use of simulation models can project some concrete result generating future possible evolutions for the system. A predator-prey model for extensive livestock systems -called PPGL- was set to understand the impact of that spring forage stash module on animal securing parameter, expressed as the proportion of adult rearing cows maintaining liveweight at summer grazing on a drought scenario. Results suggest that the stashing 10% of the farm surface can save approximatively 70% of rearing cows, even for drought episodes on closing time or in the summer grazing period. Additionally, a linear direct effect was observed between stashing surface on proportion of rearing cows secured. The resulting carrying capacity of the stash forage module is about 800 to 850 kg liveweight / ha on the grazing period, supporting high grazing pressure. Considering those results, the inclusion of a spring forage stash module is a promising tool to generate more resilient livestock production systems

Effect of Chronic Inhibition of Converting Enzyme on Renal Handling of Salt and Water: A Study on a Pediatric Population

Background/Aims: The effect of angiotensin-converting enzyme inhibition (ACEi) is amply documented in several pathological conditions. However, there are few reports about the effect of chronic ACEi on salt and water balance. The present work evaluates the effect of chronic ACEi on salt and water balance in a population of children receiving enalapril chronically in order to reduce albuminuria elicited by a uremic hemolytic syndrome. Methods: Nine children aged from 9 to 19 years with normal glomerular filtration rate, normotension and with urinary concentration capacity preserved were treated with enalapril with doses ranging between 0.1 and 0.30 mg/kg/day. Diuresis, urinary absolute and fractional excretion of Na+, K+ and urea, creatinine clearance, osmolal clearance and tubular water reabsorption were measured under three experimental procedures: (1) with free access to water; (2) with a water load and (3) with water restriction. In the last group urinary antidiuretic hormone (ADH) was measured. These tests were performed in a paired way, just before starting ACEi treatment and after 6 months of enalapril treatment. Results: Enalapril treatment diminished the urinary concentration capacity without affecting Na+ and K+ urinary excretion. Creatinine clearance was not modified except in the condition of water load where a fall in it was found after ACEi. ADH increased after enalapril treatment in children under water restriction. Conclusion: In these children chronic ACEi decreases urinary concentration capacity.Fil: Dieguez, S. M.. Gobierno de la Ciudad de Buenos Aires.

Developing Frameworks to Assess Impacts of Multiple Drivers of Change on Grassland System

Grassland systems face many simultaneous pressures including market and policy compliance that operate from local to global scale. The ability to adapt to these pressures against a background of constrained natural resources and inputs is vital to the continued success of the grassland livestock industry and all those dependent on its outputs. New Zealand and Uruguay collaborators have been developing a suite of tools and processes embedded in an “innovation platform” to enable farmers, agribusiness and policy planners to engage and collectively learn about the impact of their interacting individual decisions and strategies. We describe the generic framework and demonstrate examples of the tools and processes used and their applicability across scale in both New Zealand and Uruguay

High-performance visible light photodetectors based on inorganic CZT and InCZT single crystals

Herein, the optoelectrical investigation of cadmium zinc telluride (CZT) and indium (In) doped CZT (InCZT) single crystals-based photodetectors have been demonstrated. The grown crystals were configured into photodetector devices and recorded the current-voltage (I-V) and current-time (I-t) characteristics under different illumination intensities. It has been observed that the photocurrent generation mechanism in both photodetector devices is dominantly driven by a photogating effect. The CZT photodetector exhibits stable and reversible device performances to 632 nm light, including a promotable responsivity of 0.38 AW−1, a high photoswitch ratio of 152, specific detectivity of 6.30 × 1011 Jones, and fast switching time (rise time of 210 ms and decay time of 150 ms). When doped with In, the responsivity of device increases to 0.50 AW−1, photoswitch ratio decrease to 10, specific detectivity decrease to 1.80 × 1011 Jones, rise time decrease to 140 ms and decay time increase to 200 ms. Moreover, these devices show a very high external quantum efficiency of 200% for CZT and 250% for InCZT. These results demonstrate that the CZT based crystals have great potential for visible light photodetector applicationsAuthors from KKU express their appreciation to the Deanship of Scientifc Research at King Khalid University for funding this work through research groups program under grant number R.G.P. 2/42/4

Shared Spaces and Social Integration

The pandemic caused by the SARS-COv2 virus demanded actions in universities to ensure safety public health of their community. Several fronts are working in this direction, from physical distancing and sanitation protocols, to the use of indoor and outdoor environments, which includes the circulation of pedestrians and cyclists through the campuses. The University of Campinas is carrying out a tactical urbanism project, consisting of a set of actions aimed at low-cost changes in the built environment to test possible improvements through a living laboratory that involves the entire local community. The living laboratory is an innovative systemic approach that enables the integration of research and innovation in a territorial context through co-creation that involves the local community. The objective of the living laboratory of tactical urbanism at Unicamp is to encourage and guide the circulation of pedestrians and cyclists on the campuses in conditions that ensure physical distance. For this, workshops, questionnaires, decisions and collaborative actions are carrying out, so the community is involved in all stages of the project. After the situational survey and planning, actions should involve surface design with patterns and artistic paintings along the streets in order to promote shared use between modes of transport with special consideration for pedestrians and cyclists. As a result, it is expected that Unicamp will be able to restart face-to-face activities during the pandemic with public safety, mobility and low investment.Keyword: Sustainable Urban Mobility, Pedestrian, Cyclist, Sustainable Campu
