La Influencia de la Motivación Laboral en los Trabajadores del Comisariato Policía Nacional del departamento de Matagalpa. Año 2013

En la presente investigación se estudió la influencia de la motivación laboral en los trabajadores del Comisariato Policía Nacional del departamento de Matagalpa, durante el Año 2013, esto con el propósito de analizar la influencia de la motivación laboral de los trabajadores. Dicho estudio es de gran importancia, porque a través de éste, permitirá al lector interesado en el tema, tomar en consideración las técnicas y factores que influyen en una motivación aceptable para los empleados de las instituciones presentes en el departamento de Matagalpa y principalmente a los trabajadores del Comisariato. Los resultados obtenidos mostraron que el comisariato cuenta con ciertos elementos de la motivación aplicado a sus empleados como: el dinero, calidad de vida laboral, enriquecimiento del puesto y participación en ciertas ocasiones, pero es necesario aun mejorarlos debido a que no existe una constante aplicación de un sistema de motivación adecuado que abarque a todos los empleados de la organización, generándoles satisfacción a todos. Como parte de la influencia de la motivación laboral en los trabajadores estos elementos son considerados de importancia y necesarias de su aplicación, con esto se podría mejorar, a través de una buena estrategia se llegaría a satisfacer las necesidades y se obtendría un personal motivado. Es por ello que es necesario que la dirección administrativa del comisariato establezca mejores técnicas motivacionales y factores que lo conlleven a tener personal satisfecho con alto nivel de la motivación que permitirá la ejecución de actividades con eficiencia y eficaci

Contributos da tecnologia para a sustentabilidade da rega na fruticultura do Algarve

O regadio em Portugal nos últimos anos tem levantado questões, quer a nível estratégico, quer a nível de gestão. Ano após ano os níveis de precipitação têm vindo a diminuir, enquanto as áreas de regadio têm vindo a aumentar. A utilização da água na agricultura dispõe cada vez mais de meios tecnológicos de suporte que auxiliam o agricultor nas tomadas de decisão. Centrando as atenções na principal região produtora de citrinos e abacates em Portugal, as situações de seca que o Algarve atravessa põem as capacidades dos técnicos agrícolas à prova, com o objetivo de desenvolver técnicas cada vez mais eficazes na gestão hídrica, ao mesmo tempo que se mantem a produção e a qualidade das culturas frutícolas.info:eu-repo/semantics/publishedVersio

Characterization and expression analysis of WRKY genes during leaf and corolla senescence of Petunia hybrida plants

Several families of transcription factors (TFs) control the progression of senescence. Many key TFs belonging to the WRKY family have been described to play crucial roles in the regulation of leaf senescence, mainly in Arabidopsis thaliana. However, little is known about senescence-associated WRKY members in floricultural species. Delay of senescence in leaves and petals of Petunia hybrida, a worldwide ornamental crop are highly appreciated traits. In this work, starting from 28 differentially expressed WRKY genes of A. thaliana during the progression of leaf senescence, we identified the orthologous in P. hybrida and explored the expression profiles of 20 PhWRKY genes during the progression of natural (age-related) leaf and corolla senescence as well as in the corollas of flowers undergoing pollination-induced senescence. Simultaneous visualization showed consistent and similar expression profiles of PhWRKYs during natural leaf and corolla senescence, although weak expression changes were observed during pollination-induced senescence. Comparable expression trends between PhWRKYs and the corresponding genes of A. thaliana were observed during leaf senescence, although more divergence was found in petals of pollinated petunia flowers. Integration of expression data with phylogenetics, conserved motif and cis-regulatory element analyses were used to establish a list of candidates that could regulate more than one senescence process. Our results suggest that several members of the WRKY family of TFs are tightly linked to the regulation of senescence in P. hybrida.Fil: Astigueta, Francisco Horacio.

HIV-1 drug resistance before initiation or re-initiation of first-line antiretroviral therapy in low-income and middle-income countries: a systematic review and meta-regression analysis.

BACKGROUND: Pretreatment drug resistance in people initiating or re-initiating antiretroviral therapy (ART) containing non-nucleoside reverse transcriptase inhibitors (NNRTIs) might compromise HIV control in low-income and middle-income countries (LMICs). We aimed to assess the scale of this problem and whether it is associated with the intiation or re-initiation of ART in people who have had previous exposure to antiretroviral drugs. METHODS: This study was a systematic review and meta-regression analysis. We assessed regional prevalence of pretreatment drug resistance and risk of pretreatment drug resistance in people initiating ART who reported previous ART exposure. We systematically screened publications and unpublished datasets for pretreatment drug-resistance data in individuals in LMICs initiating or re-initiating first-line ART from LMICs. We searched for studies in PubMed and Embase and conference abstracts and presentations from the Conference on Retroviruses and Opportunistic Infections, the International AIDS Society Conference, and the International Drug Resistance Workshop for the period Jan 1, 2001, to Dec 31, 2016. To assess the prevalence of drug resistance within a specified region at any specific timepoint, we extracted study level data and pooled prevalence estimates within the region using an empty logistic regression model with a random effect at the study level. We used random effects meta-regression to relate sampling year to prevalence of pretreatment drug resistance within geographical regions. FINDINGS: We identified 358 datasets that contributed data to our analyses, representing 56 044 adults in 63 countries. Prevalence estimates of pretreatment NNRTI resistance in 2016 were 11·0% (7·5-15·9) in southern Africa, 10·1% (5·1-19·4) in eastern Africa, 7·2% (2·9-16·5) in western and central Africa, and 9·4% (6·6-13·2) in Latin America and the Caribbean. There were substantial increases in pretreatment NNRTI resistance per year in all regions. The yearly increases in the odds of pretreatment drug resistance were 23% (95% CI 16-29) in southern Africa, 17% (5-30) in eastern Africa, 17% (6-29) in western and central Africa, 11% (5-18) in Latin America and the Caribbean, and 11% (2-20) in Asia. Estimated increases in the absolute prevalence of pretreatment drug resistance between 2015 and 2016 ranged from 0·3% in Asia to 1·8% in southern Africa. INTERPRETATION: Pretreatment drug resistance is increasing at substantial rate in LMICs, especially in sub-Saharan Africa. In 2016, the prevalence of pretreatment NNRTI resistance was near WHO's 10% threshold for changing first-line ART in southern and eastern Africa and Latin America, underscoring the need for routine national HIV drug-resistance surveillance and review of national policies for first-line ART regimen composition.

Impact of hospital characteristics on implementation of a Pediatric Early Warning System in resource-limited cancer hospitals

BackgroundPediatric Early Warning Systems (PEWS) aid in identification of deterioration in hospitalized children with cancer but are underutilized in resource-limited settings. Proyecto EVAT is a multicenter quality improvement (QI) collaborative in Latin America to implement PEWS. This study investigates the relationship between hospital characteristics and time required for PEWS implementation.MethodsThis convergent mixed-methods study included 23 Proyecto EVAT childhood cancer centers; 5 hospitals representing quick and slow implementers were selected for qualitative analysis. Semi-structured interviews were conducted with 71 stakeholders involved in PEWS implementation. Interviews were recorded, transcribed and translated to English, then coded using a priori and novel codes. Thematic content analysis explored the impact of hospital characteristics and QI experience on time required for PEWS implementation and was supplemented by quantitative analysis exploring the relationship between hospital characteristics and implementation time.ResultsIn both quantitative and qualitative analysis, material and human resources to support PEWS significantly impacted time to implementation. Lack of resources produced various obstacles that extended time necessary for centers to achieve successful implementation. Hospital characteristics, such as funding structure and type, influenced PEWS implementation time by determining their resource-availability. Prior hospital or implementation leader experience with QI, however, helped facilitate implementation by assisting implementers predict and overcome resource-related challenges.ConclusionsHospital characteristics impact time required to implement PEWS in resource-limited childhood cancer centers; however, prior QI experience helps anticipate and adapt to resource challenges and more quickly implement PEWS. QI training should be a component of strategies to scale-up use of evidence-based interventions like PEWS in resource-limited settings

Geographic and temporal trends in the molecular epidemiology and genetic mechanisms of transmitted HIV-1 drug resistance:an individual-patient- and sequence-level meta-analysis

Regional and subtype-specific mutational patterns of HIV-1 transmitted drug resistance (TDR) are essential for informing first-line antiretroviral (ARV) therapy guidelines and designing diagnostic assays for use in regions where standard genotypic resistance testing is not affordable. We sought to understand the molecular epidemiology of TDR and to identify the HIV-1 drug-resistance mutations responsible for TDR in different regions and virus subtypes.status: publishe
