Level of Science Achievement: Basis for the Production of Strategic Intervention Materials (SIMs)

This research used the descriptive method to determine the level of Science Achievement of Grade VI Pupils: Basis for Production of Strategic Intervention Materials in Bayawan City East Central School, Bayawan City Division during the SY 2019-2020. The quantitative data were gathered from 134 pupils of Bayawan City East Central School, Bayawan City Division during the SY 2019-2020. Also, the researcher conducted a survey questionnaire. Descriptive method was used in this study. The statistical tools used in the analysis of the data were percentage, frequency, mean, weighted mean, and z-test. The study found out that the level of Science Achievement of Grade VI Learners of the Least Learned Organ Systems in terms of the Circulatory System, Respiratory System, and Excretory System were at low mastery level while for the Nervous System, the learners were moving towards mastery stage. Based on the given findings, it served as a basis for the production of Strategic Intervention Materials (SIM) in the different Least Learned Organ Systems namely Circulatory System, Respiratory System, Nervous System, and Excretory System in order to increase the level of learners’ achievement in Science subject

Evaluating elbow osteoarthritis within the prehistoric Tiwanaku state using generalized estimating equations (GEE).

OBJECTIVES:Studies of osteoarthritis (OA) in human skeletal remains can come with scalar problems. If OA measurement is noted as present or absent in one joint, like the elbow, results may not identify specific articular pathology data and the sample size may be insufficient to address research questions. If calculated on a per data point basis (i.e., each articular surface within a joint), results may prove too data heavy to comprehensively understand arthritic changes, or one individual with multiple positive scores may skew results and violate the data independence required for statistical tests. The objective of this article is to show that the statistical methodology Generalized Estimating Equations (GEE) can solve scalar issues in bioarchaeological studies. MATERIALS AND METHODS:Using GEE, a population-averaged statistical model, 1,195 adults from the core and one colony of the prehistoric Tiwanaku state (AD 500-1,100) were evaluated bilaterally for OA on the seven articular surfaces of the elbow joint. RESULTS:GEE linked the articular surfaces within each individual specimen, permitting the largest possible unbiased dataset, and showed significant differences between core and colony Tiwanaku peoples in the overall elbow joint, while also pinpointing specific articular surfaces with OA. Data groupings by sex and age at death also demonstrated significant variation. A pattern of elbow rotation noted for core Tiwanaku people may indicate a specific pattern of movement. DISCUSSION:GEE is effective and should be encouraged in bioarchaeological studies as a way to address scalar issues and to retain all pathology information

A methodology to downscale water demand data with application to the Andean region (Ecuador, Peru, Bolivia, Chile)

Mountainous regions are a hotspot for water scarcity and anthropogenic pressure on water resources. Substantial uncertainty surrounds projections of future climate and water availability. Furthermore, quantitative and distributed data on water demand are generally scarce, dispersed, and highly heterogeneous. This forms a major bottleneck to studying water resources issues and developing strategies to improve water resource management. Here we present a methodology to produce and evaluate high-resolution gridded maps of anthropogenic surface water demand with application to the Andean region. These data are disaggregated according to the major types of water demand: domestic users, irrigated area, and hydropower. This dataset was built by homogenizing, integrating, and interpolating data obtained from various national institutions in charge of water resource management as well as relevant global datasets. The maps can be used to research anthropogenic impacts on water resources, and to guide regional decision-making in regions such as the Andes

The Oldest Case of Decapitation in the New World (Lapa do Santo, East-Central Brazil)

We present here evidence for an early Holocene case of decapitation in the New World (Burial 26), found in the rock shelter of Lapa do Santo in 2007. Lapa do Santo is an archaeological site located in the Lagoa Santa karst in east-central Brazil with evidence of human occupation dating as far back as 11.7-12.7 cal kyBP (95.4% interval). An ultra-filtered AMS age determination on a fragment of the sphenoid provided an age range of 9.1-9.4 cal kyBP (95.4% interval) for Burial 26. The interment was composed of an articulated cranium, mandible and first six cervical vertebrae. Cut marks with a v-shaped profile were observed in the mandible and sixth cervical vertebra. The right hand was amputated and laid over the left side of the face with distal phalanges pointing to the chin and the left hand was amputated and laid over the right side of the face with distal phalanges pointing to the forehead. Strontium analysis comparing Burial 26's isotopic signature to other specimens from Lapa do Santo suggests this was a local member of the group. Therefore, we suggest a ritualized decapitation instead of trophy-taking, testifying for the sophistication of mortuary rituals among hunter-gatherers in the Americas during the early Archaic period. In the apparent absence of wealth goods or elaborated architecture, Lapa do Santo's inhabitants seemed to use the human body to express their cosmological principles regarding death

Estudio de seroprevalencia de enfermedad de Chagas-Mazza en residentes del Cinturón Hortícola Platense

La Enfermedad de Chagas-Mazza, es silenciosa, frecuentemente ocasiona lesiones sin notables manifestaciones clínicas. Numerosas personas desconocen su condición de afectados por Tripanosoma cruzi. Cuando ellas tienen acceso a diagnósticos clínicos y seroepidemiológicos, puede ocurrir que haga ya muchos años que han sido afectados y haya daños orgánicos. En este estudio se realizaron actividades en territorio, en el cinturón frutihortícola platense en el que habitan personas provenientes de áreas endémicas de Enfermedad de Chagas-Mazza, como parte de un proyecto integral. Con consentimiento informado se realizaron extracciones y diagnósticos. Las personas seropositivas fueron luego estudiadas, seguidas y medicadas según cada caso siguiendo las indicaciones establecidas en los protocolos vigentes consensuados. Ellos no conocían su condición de afectados. Es necesario incrementar las acciones en el territorio a efectos de realizar diagnósticos tempranos y acciones oportunas.Chagas-Mazza disease is silent, frequently causes lesions without manifestations. notable clinical Many people are unaware of their status as affected by Trypanosoma cruzi. When they have access to clinical and seroepidemiological diagnoses, it may happen that they have been affected for years and there is organic damage. In this study, activities were carried out in the territory, in the La Plata fruit and vegetable belt where people from endemic areas of Chagas-Mazza disease live, as part of a comprehensive project. With informed consent, extractions and diagnoses were performed.

A principled approach to REPL interpreters

Read-eval-print-loops (REPLs) allow programmers to test out snippets of code, explore APIs, or even incrementally construct code, and get immediate feedback on their actions. However, even though many languages provide a REPL, the relation between the language as is and what is accepted at the REPL prompt is not always well-defined. Furthermore, implementing a REPL for new languages, such as DSLs, may incur significant language engineering cost. In this paper we survey the domain of REPLs and investigate the (formal) principles underlying REPLs. We identify and define the class of sequential languages, which admit a sound REPL implementation based on a definitional interpreter, and present design guidelines for extending existing language implementations to support REPL-style interfaces (including computational notebooks). The obtained REPLs can then be generically turned into an exploring interpreter, to allow exploration of the user’s interaction.The approach is illustrated using three case studies, based on MiniJava, QL (a DSL for questionnaires), and eFLINT (a DSL for normative rules). We expect sequential languages, and the consequent design principles, to be stepping stones towards a better understanding of the essence of REPLs.</p

Evaluation of post-surgical cognitive function and protein fingerprints in the cerebro-spinal fluid utilizing surface-enhanced laser desorption/ionization time-of-flight mass-spectrometry (SELDI-TOF MS) after coronary artery bypass grafting: Review of proteomic analytic tools and introducing a new syndrome

Cognitive dysfunction following surgery is a common complication, which increases the incidence of other co-morbid conditions, hospital and health-care costs. The reported rate of the occurrence of post-operative cognitive decline varies with different studies, depending on population profile, type of surgery, definition of cognitive disorder and detection methods, design of study, etc. It remains unclear whether these psychiatric signs and symptoms are direct results of the effects of surgery or general anesthesia. Nonetheless they are more frequent after cardiac surgery and are likely to be multi-factorial, but the patho-mechanisms are not yet fully characterized. This communication provides a synopsis of proteomics tools and delineates novel SELDI-TOF results to evaluate biomarkers in this regard. Presented for the first time is a classification of the clinically relevant forms of post-operative cognitive decline with the advent of a novel subclass. © 2011 Bentham Science Publishers Ltd

Human Resource Flexibility as a Mediating Variable Between High Performance Work Systems and Performance

Much of the human resource management literature has demonstrated the impact of high performance work systems (HPWS) on organizational performance. A new generation of studies is emerging in this literature that recommends the inclusion of mediating variables between HPWS and organizational performance. The increasing rate of dynamism in competitive environments suggests that measures of employee adaptability should be included as a mechanism that may explain the relevance of HPWS to firm competitiveness. On a sample of 226 Spanish firms, the study’s results confirm that HPWS influences performance through its impact on the firm’s human resource (HR) flexibility
