Analysis of Influence of Independent and Board of Commissioners Managerial Ownership of Return on Assets (ROA) at PT. Adaro Energy Tbk, Period 2016-2020
Authors: . Roswaty
Published: August 2023

The purpose of this study was to determine the significance of the influence of independent commissioners and managerial ownership on ROA. This research was conducted at the Adaro Energy company in the 2016-2020 period. The data analysis technique used is multiple linear regression analysis using Eviews 10 software. Based on the results of the F test the first analysis obtained a significance value of F of 0.046390 <0.05. Then the regression has a significant effect so that it can be concluded that there is a significant simultaneous effect of the Independent Board of Commissioners and Managerial Ownership variables on Return on Assets. Based on the T test results obtained partial results of the Independent Board of Commissioners on ROA with a significance value of 0.2293> with a Coefficient regression value (-0.085447) means that the Independent Commissioner has a negative and not significant effect on ROA. That the size of the proportion of the independent commissioners in the company does not guarantee that the company's profitability is getting better and there is no fraud in the company's financial reporting. Based on the T test results obtained partially Managerial Ownership probability level of 0.0866> α 5% with Coefficient regression value (-0.692288) means Managerial Ownership has a negative and not significant effect on ROA. This situation occurs because of the small proportion of share ownership in the sample companies so that it has not been able to increase ROA.

Published: August 2023

A new mineral species, petermegawite, ideally Al6(Se4+O3)3[SiO3(OH)](OH)9⋅10H2O, was discovered at the El Dragón mine, Potosí Department, Bolivia. It occurs as aggregates of bladed or tabular crystals. Associated minerals are Co-bearing krut′aite–penroseite (matrix), chalcomenite, ‘clinochalcomenite’ (not IMA approved), molybdomenite, lepidocrocite, goethite, ahlfeldite, and calcite. Petermegawite is colorless in transmitted light and transparent with a white streak and vitreous luster. It is brittle and has a Mohs hardness of 2–2½. Cleavage is perfect on {001}. The measured and calculated densities are 2.27(5) and 2.32 g/cm3, respectively. Optically, petermegawite is biaxial (+), with α = 1.545(5), β = 1.554(5), γ = 1.567(5) (white light). An electron microprobe analysis yielded an empirical formula (based on 10 non-H cations pfu) of Al6.00[(Se0.89S0.11)Σ1.00O3]3[(Si0.90Al0.07)Σ0.97O2.81(OH)1.19](OH)9⋅10H2O, which can be simplified to Al6[(Se,S)O3]3[(Si,Al)O3(OH)](OH)9⋅10H2O.

Petermegawite is orthorhombic, space group Cmc21 with unit-cell parameters a = 16.2392(2), b = 10.96370(10), c = 15.3367(2) Å, V = 2730.57(5) Å3, and Z = 4. Its crystal structure is characterized by clusters of six-membered rings of edge-sharing AlO6 octahedra with an SiO3(OH) tetrahedron situated at the center of each ring and three Se4+O3 triangular pyramids appended outside the ring. These clusters are joined together by hydrogen bonds to form heteropolyhedral layers parallel to (001). The H2O molecules that are not bonded to any non-H cations are sandwiched between the layers. The cluster formed by a six-membered AlO6 octahedral ring with an SiO3OH tetrahedron at the center of the ring in petermegawite has the composition [Al6(SiO3OH)O6(OH)9(H2O)6]6−. It is topologically identical to the clusters of composition [Al6(AsO4)O7(OH)9(H2O)5]8− that are found in bettertonite and penberthycroftite. As a new polyoxometalate building block, this type of cluster may be expressed with a general chemical formula [TM6X25], where T = tetrahedrally coordinated cation, M = octahedrally coordinated cation, and X = O, OH, H2O.

Assisted self-help housing is a process whereby people are actively involved in the decision-making of their homes’ consolidation, receiving tools to better manage resources in building them. While such support is embedded within urban and regional systems, evolving forms of state intervention have received little attention in the literature. In this article, we focus on federal assisted self-help housing programmes in Mexico, where this approach became formalised by the early 2000s. Recent governments positioned assisted self-help housing – at least on paper – as key for Mexico’s housing agenda. What we term Mexico’s
housing governability system
has continuously evolved, yet its capacity to address housing needs is challenged. We show that policy and institutional change in Mexico reflect a continuing pathway over several decades to include assisted self-help policies in the housing governability system. We highlight the nonlinear nature of policy development and the paradoxes of formalising flexible selfhelp approaches.

Authors: Evans Nancy Remage , Ferrari Mckenzie G. , Kuraszkiewicz Joanna , Silverberg Steven , Nichols Joy , Torres Guillermo , Fischbach Makenzi
Published: August 2023

Ultraviolet spectra were taken of 25 detached eclipsing binaries (DEBs) with spectral types O, B, and early A with the International Ultraviolet Explorer satellite in the 1150–1900 Å region. The spectra were compared with BOSZ model atmospheres. The composite spectra of the DEBs were modeled by a combination of models representing the hot and cool components, and the temperatures of the hottest components of the systems were determined. From these temperatures a direct mass–temperature relation was obtained for stars close to the main sequence with solar metallicity for B and early A stars: log M/M
⊙ = −5.90 ± 0.27 + (1.56 ± 0.07) × log T. This relation allows a mass to be inferred for comparable stars from an ultraviolet spectrum. The five chemically peculiar Am stars in the sample have larger radii than normal A stars of the same mass.

Authors: Lyubenova Daniela , Dimitrova Antoaneta , Grigorova-Petrova Kristin , Mitova Michaela
Published: August 2023

BACKGROUND: Autonomous elderly are generally healthy persons in stable clinical status, who do not have any exacerbations, despite of the presence of chronic polymorbidity. Video games for rehabilitation (VGR) could provide more fun and emotion in the routine physiotherapy (PT) sessions and to attract more people stay physically active.
AIM: The aim of the study was to evaluate the effect of self-designed 3D camera VGR on mobility and motor abilities in generally healthy older people.
MATERIALS AND METHODS: The type of the research is an experimental single-centered study, pre-test and post- test design, conducted at a physical rehabilitation outpatient center. The study is conducted with fifty healthy older people, divided into two groups. The assignment into two groups was according to the preference of the participants to attend video games after routine PT sessions for 7 weeks, 3 times weekly. The experimental group (EG) included 24 women (mean age 76.75 ± 6.89) and the control group consisted of 26 women (mean age 73.69 ± 6.89). The persons were allocated according to their willingness to participate in the study and inclusion (age above 65 years, cooperative, agreeing to participate, and willing to sign a consent form) and exclusion criteria (current exacerbation of a chronic disease, sudden onset of an acute illness, or trauma). The effect on the calf muscle mass, balance, and gait in both groups after the intervention, was evaluated by calf centimetry, Romberg test, functional reach test, 5 times sit-to-stand test, and 10-m walk test.
RESULTS: The applied video games positively affected the functional mobility, strength, and endurance of the lower limbs in the EG. Significant differences between the groups were found regarding static standing balance (p < 0.01), functional balance (p < 0.05), and maximum speed gait (p < 0.05) assessed by Mann–Whitney U-test, Wilcoxon, and Student’s t-test.
CONCLUSION: The present self-designed video game applied as an additional intervention was more effective than conventional PT alone in mobility, balance, and gait in apparently healthy older people.

Authors: Villarreal Osvaldo , Ahumada-C. Daniela , Delgado-Santa Leonardo
Published: August 2023

Colombia is a biodiverse country with 1,486 protected areas covering almost 50 million hectares, yet little is known about the biodiversity they harbor, particularly in terms of harvestmen (Arachnida: Opiliones). This study provides a comprehensive updated summary of the armored harvestmen (Laniatores) species found in Colombia with a list of 173 nominal species, focusing on the Laniatores fauna found in protected areas and its diversity is detailed and analyzed. Maps with all records associated with ecoregions and protected areas in Colombia are presented. Additionally, three new Laniatores species are described here:Phalangodus andresisp. nov.from the department of Cundinamarca, andVentrifurca phallainasp. nov.andAmpycella fortunatasp. nov.from the department of Valle del Cauca; and a new family assignment is proposed forParaphalangodusRoewer, 1915, placing it in the family Nomoclastidae. Information available on Laniatores in the National System of Protected Areas is still scarce and promoting strategies to facilitate the regulatory procedures for collecting specimens in these areas and increasing investment in basic science projects, are suggested to improve the understanding and study of the Laniatores fauna and other invertebrates in Colombia. Finally, a chronicle and timeline set of figures of species of Laniatores from Colombia, described by various authors during three periods, is given.
FastCAT: A framework for fast routing table calculation incorporating multiple protocols
Authors: Cai Jianfei , Yang Guozheng , Liu Jingju , Xie Yi
Published: August 2023

Currently, most network outages occur because of manual configuration errors. Therefore, it is essential to verify the correctness of network configurations before deployment. Computing the network control plane is a key technology for network configuration verification. We can verify the correctness of network configurations for fault tolerance by generating routing tables, as well as connectivity. However, existing routing table calculation tools have disadvantages such as lack of user-friendliness, limited expressiveness, and slower speed of routing table generation. In this paper, we present FastCAT, a framework for computing routing tables incorporating multiple protocols. FastCAT can simulate the interaction of multiple routing protocols and quickly generate routing tables based on configuration files and topology information. The key to FastCAT's performance is that FastCAT focuses only on the final stable state of the OSPF and IS-IS protocols, disregarding the transient states during protocol convergence. For RIPv2 and BGP, FastCAT computes the current protocol routing tables based on the protocol's previous state, retaining only the most recent protocol routing tables in the latest state. Experimental evaluations have shown that FastCAT generates routing tables more quickly and accurately than the state-of-the-art routing simulation tool, in a general network of around 200 routers.
Solving problems involving numerical integration (Ⅱ): Modified Simpson's methods for equal intervals of odd numbers
Authors: Guo William
Published: August 2023

The trapezium and Simpson's methods are widely used for numerical integration. In most circumstances, Simpson's method is more accurate than the trapezium method but only applicable to cases with equal intervals of even numbers. This technical note reports the formulation of two modified Simpson's methods, the trapezium-corrected Simpson's method (TCSM) and cubic-corrected Simpson's method (CCSM), as general-purpose symmetric formulas to solve numerical integrations with equal intervals of odd numbers (n ≥ 5) with the same level of accuracy as that of Simpson's method applied to the even number near n. Error analysis in terms of the order of error bound and case studies in this note demonstrate and validate the usefulness of the proposed formulas for solving different types of theoretical problems and real-world applications. In terms of accuracy of approximation for cases with equal intervals of odd numbers, CCSM performs better than TCSM by at least one order in error bound whereas TCSM performs better than the trapezium method by at least one order in error bound.

In vitro germplasm conservation allows to extend the interval between subcultures without compromising the viability and genetic integrity of the plant, ensuring a backup of genotypes with high phytosanitary quality. Thus, this study aimed to verify the effect of four concentrations of Paclobutrazol® in inducing minimum growth in five Manihot esculenta accessions from the in vitro Active Germplasm Bank of Embrapa Cassava and Fruits. An experiment was installed using the Murashige and Skoog medium without addition and added with four concentrations of Paclobutrazol® (0.10, 0.20, 0.30, and 0.40 mg L-1), in five in vitro accessions of M. esculenta: BRS Jari (BGM 2041), Cigana (BGM 0264), BRS Poti Branca (BGM 2017), TME 14, and BRS Novo Horizonte. The statistical design was completely randomized in a 5 x 5 factorial scheme, with 15 repetitions. After 120 days of cultivation, the following variables were evaluated: plant height (cm), number of green leaves, number of senescent leaves, number of mini-cuttings, number of shoots, and fresh and dry mass of shoots and roots (mg). Paclobutrazol® caused a reduction in plant height and gain in root mass for all accessions, in addition to preserving the number of green leaves and decreasing leaf senescence for most genotypes. There was a strong dependence of the genotype in relation to the concentration of Paclobutrazol®. The concentration of 0.20 mg L-1 showed potential in the in vitro conservation of M. esculenta genotypes.

Published: August 2023

Extracorporeal membrane oxygenation (ECMO) is a form of extracorporeal life support which provides cardiorespiratory support to patients with potentially reversible pathophysiological processes. ECMO has evolved over the past few decades as a standard technology for neonatal severe respiratory support. However, its use in the pediatric population has increased only since 2009. We report a case of a 9-month infant who required a prolonged (789 h) venoarterial ECMO for severe acute respiratory distress consequent to pneumonia probably secondary to aspiration. He was discharged after this prolonged ECMO run without any obvious unfavorable outcome and is neurodevelopmentally sound at a 26-month follow-up.

Authors: Gnanasuriyan Ramachandran , Patnaik Satyadarshi , Patro Sibasish , Mohanty Indrani
Published: August 2023

Background:

Recurrent dermatophytosis is a pressing problem worldwide due to inadequate treatment, drug resistance, and indiscriminate use of topical steroids. This scenario increases the need for the study of risk factors and antifungal susceptibility testing. There is a paucity of information on this subject.

Objective:

We aimed to find the clinico-mycological pattern of recurrent dermatophytic infections, the factors responsible for recurrence and determine the sensitivity pattern of isolates against four antifungals (fluconazole, itraconazole, terbinafine, and amphotericin B).

Materials and Methods:

Patients with recurrent dermatophytosis attending the outpatient Department of Our Tertiary Care Institute were enrolled in this study. A detailed history was taken; clinical examination was done; samples were collected for mycological examinations, and in-vitro antifungal sensitivity testing was done by broth microdilution method as per Clinical and Laboratory Standard Institute M38-A guidelines.

Results:

One hundred and twenty-eight patients were included in the study with a male:female ratio of 1.38:1. The most commonly affected age group was 31–40 years. Tinea corporis with tinea cruris was the most common type of clinical presentation. Potassium hydroxide mount was positive in 53 samples and culture was positive in 59 samples. Trichophyton rubrum was the predominant species isolated, followed by Trichophyton mentagrophytes. On in-vitro antifungal susceptibility testing, itraconazole and amphotericin B had the lowest minimum inhibitory concentrations (MIC), followed by terbinafine. Fluconazole had the highest MIC among the drugs tested.

Conclusion:

Topical corticosteroid abuse, lack of personal hygiene, and habit of sharing clothes were seen in many patients with recalcitrant dermatophytosis. T. rubrum was the most common isolated species. Antifungal susceptibility testing revealed itraconazole and amphotericin B to have the lowest MIC value and fluconazole to have the highest MIC value.

Sex Difference in Arrhythmic Risks and Prognosis in Patients with Nonischemic Cardiomyopathy
Authors: Irene Chung Kwai-Kuen
Published: August 2023

Background:

Heart failure (HF) carries high mortality and comorbidities. Guidelines-directed medical and device therapy improves prognosis significantly. Although automatic intracardiac defibrillator (AICD) had 50% relative reduction in sudden cardiac deaths in patients with nonischemic cardiomyopathy (NICMP), there is no significant difference in overall mortality. Subgroup analysis of the two randomized controlled NICMP trials indicates no significant mortality benefits in female patients.

Subjects and Methods:

This single-center, retrospective study recruited 447 patients with HF and left ventricular ejection fraction (LVEF) <40% due to NICMP etiology, and those with significant coronary artery disease with more than 70% stenosis were excluded based on coronary angiogram. The primary endpoint was appropriate therapy from the device for ventricular arrhythmias and primary composite endpoints included death, appropriate therapy from device for ventricular arrhythmias and hospitalization for HF.

Results:

Female patients were older, had smaller left ventricles, narrower QRS, and higher LVEF at baseline. The mean follow-up duration was 6.18 ± 4.16 years. There were 61 deaths (13% vs. 2.20% deaths per year, 20 females and 41 males). Mean LVEF increased significantly from 24.88 ± 8.17% to 39.92 ± 13.88% in female patients and from 22.05 ± 8.52% to 36.14 ± 8.17% in male patients (P = 0.023). LVEF increased to or more than 35% in 190 patients (43%). Forty patients (9%) received AICD or cardiac resynchronization therapy and the other 81% received primary prevention. The median time from diagnosis of NICMP to appropriate device therapy for ventricular arrhythmias was 7.13 years (interquartile range 2.92–10.92 years). All the device therapy occurred in patients with LVEF <35%. 18/21 patients (86%) had appropriate therapy for ventricular arrhythmias were males. Male patients also had significantly higher composite endpoints (P = 0.0022).

Conclusions:

Guidelines-directed medical therapy improves left ventricular systolic function, reduces arrhythmic risks, and improves prognosis. The arrhythmic risk and composite endpoints are significantly higher in male than female patients.

Authors: Alghamdi Abdulkareem S. , Almuzayyen Hisham , Chowdhury Tumul
Published: August 2023

It is increasingly conceivable that elderly patients will be treated in perioperative settings as the world’s population shifts toward an older age distribution. They are more prone to a variety of unfavorable outcomes as a consequence of the physiological changes that accompany aging and the coexistence of multiple medical conditions. Postoperative complications in elderly patients are linked to a large increase in morbidity and mortality and the burden placed on the healthcare system. Our goal is to determine how elderly patients’ recovery after anesthesia differs from that of younger patients. In addition, we will discuss the main postoperative complications experienced by elderly patients and the measures that are utilized to limit the risk of these complications developing.

Authors: Greco Massimiliano , Calgaro Giulio , Cecconi Maurizio
Published: August 2023

An increasing proportion of surgical procedures involves elderly and frail patients in high-income countries, leading to an increased risk of postoperative complications. Complications significantly impact patient outcomes and costs, due to prolonged hospitalization and loss of autonomy. Consequently, it is crucial to evaluate preoperative functional status in older patients, to tailor the perioperative plan, and evaluate risks. The hospital environment often exacerbates cognitive impairments in elderly and frail patients, also increasing the risk of infection, falls, and malnutrition. Thus, it is essential to work on dedicated pathways to reduce hospital readmissions and favor discharges to a familiar environment. In this context, the use of wearable devices and telehealth has been promising. Telemedicine can be used for preoperative evaluations and to allow earlier discharges with continuous monitoring. Wearable devices can track patient vitals both preoperatively and postoperatively. Preoperative education of patient and caregivers can improve postoperative outcomes and is favored by technology-based approach that increases flexibility and reduce the need for in-person clinical visits and associated travel; moreover, such approaches empower patients with a greater understanding of possible risks, moving toward shared decision-making principles. Finally, caregivers play an integral role in patient improvement, for example, in the prevention of delirium. Hence, their inclusion in the care process is not only advantageous but essential to improve perioperative outcomes in this population.

Experimental study of NIST Statistical Test Suite ability to detect long repetitions in binary sequences
Authors: Zubkov Andrei Mikhailovich , Serov Aleksandr Aleksandrovich
Published: August 2023

Представлены и обсуждаются результаты эмпирического тестирования возможности обнаружения длинных повторов в двоичных последовательностях набором статистических тестов NIST. Набор детерминированных двоичных последовательностей, которые не отклоняются пакетом NIST, искажается детерминированным образом. Для того чтобы повредить двоичную последовательность, выбирается несколько ее подстрок фиксированной длины и каждая подстрока дублируется в случайном месте последовательности. Длина повторяющихся подстрок была выбрана значительно большей типичной длины самой длинной повторяющейся подстроки. Если количество повторяющихся подстрок в поврежденной последовательности невелико, то пакет NIST не отклоняет такие неслучайные криптографически слабые двоичные последовательности. Описан алгоритм, реализующий поиск самого длинного повторения подстрок в двоичной последовательности длины $n$. Этот алгоритм основан на дереве суффиксов, и его временная и пространственная сложности имеют порядок $O(n)$.

Emissions and effects of climate change have prompted study into fuels that
reduce global dependence on traditional fuels. This study seeks to investigate
engine performance, thermochemical properties, emissions, and perform NVH
analysis of Jet-A and S8 using a single-stage turbojet engine at three engine
speeds. Experimental Jet-A results were used to validate a CFX simulation of the
engine. Engine performance was quantified using thermocouples, pressure sensors,
tachometers, flow meters, and load cells fitted to the engine. Emissions results
were collected using an MKS Multigas Emissions Analyzer that examined CO, CO₂,
H₂O, NOx, and THC. NVH analysis was conducted using a multifield, free-field
microphone, and triaxial accelerometer. This study found that Jet-A operates at
higher temperatures and pressures than S8, and S8 requires higher fuel flow
rates than Jet-A, leading to poorer efficiency and thrust. S8 produced stronger
vibrations over 5 kHz compared to Jet-A. S8 showed a decrease in all measured
emissions. The CFD model was validated, showing an increase in temperature,
pressure, and gas velocity as speed increased. The swirl effect of combustion
was examined, improving atomization. Emissions contours were validated by
experimental results, showing increases in CO₂, H₂O, and NOx, and a decrease in
CO as speed increases.

Infections caused by resistant Gram-negative bacteria are a serious public health problem, with Klebsiella spp. being the most common cause and increasing over the years. There is a striking increase in antibiotic resistance worldwide. The aim of this study was to retrospectively evaluate the characteristics and treatment of bloodstream infections (BSIs) caused by Klebsiella spp. and to identify possible risk factors for extended-spectrum β-lactamase (ESBL) resistance in our hospital between August 2019 and March 2023. Of 250 Klebsiella isolates, 112 (44.8%) were ESBL producers and 138 (55.2%) were ESBL nonproducers. Catheter-related BSIs (CRBSIs) accounted for 49.6% of infections and were more common in the ESBL nonproducer group. Most of the Klebsiella spp. were K. pneumoniae (233/250). Most of the infections were healthcare-associated infections (85.6%). Most patients had an underlying disease, the most common underlying disease in the ESBL-producing group was neurometabolic disease (26.8%), whereas in the ESBL-non-producing group it was malignancy (35.5%). The median age of the ESBL-producing group was 14 months and was younger (p=0.01). Previous antibiotic use in the last 30 days, especially aminoglycosides (p<0.006), β-lactam-β-lactamase inhibitor combinations (p<0.001) and cephalosporins (p<0.001), increased ESBL-resistant infection. Use of β-lactam-β-lactamase inhibitor combinations in the last 30 days increased the risk of ESBL resistance by approximately 7.4 times, and cephalosporins increased the risk by 5 times. In the ESBL-producing group, the median duration of treatment was longer at 14 days (p=0.01), and carbapenems were most commonly used (p<0.001). Thrombocytopenia (p=0.003), elevated C-reactive protein (p<0.001), CRBSI (p=0.009), presence of central venous catheter (p=0.03), urinary catheter (p<0.001), mechanical ventilation (p<0.001), intensive care admission (p=0.005), previous use of carbapenems, aminoglycosides, fluoroquinolones in the last 30 days (p=0.003, p=0.001, p=0.006, respectively) and colistin treatment (p<0.001) increased the risk of mortality. The 28-day mortality rate was 11.6%. Appropriate use of narrow-spectrum antibiotics and reduction of invasive procedures is important in reducing ESBL resistance and BSI-related mortality.
Factors Associated With Regular Dental Care in People With Spinal Cord Injury: A Secondary Analysis of Data From the FRASCI Study
Authors: Coker Jennifer , Sevigny Mitch , Nguyen Nguyen , Battaglino Ricardo , Morse Leslie
Published: August 2023

Background

Oral health and regular dental care are critical to overall health. Research has found associations between oral health and infections, respiratory disease, and poor quality of life in the general population. While risks for all are increased in people with spinal cord injury (SCI), there is limited information on dental care after SCI.

Objectives

The purpose of this analysis was to examine factors associated with regular dental care in people with SCI.

Methods

We analyzed data from 348 individuals with traumatic and nontraumatic SCI who were enrolled in the Fracture Risk after SCI (FRASCI) study. The dataset included two variables on dental care, as well as demographics, injury-related characteristics, and secondary conditions. Bivariate relationships were determined using two-sided t tests and chi-square tests.

Results

Over 60% of the sample received regular dental care twice per year, and 71% reported seeing a dentist within the past year. Those participants receiving regular dental care twice a year were more likely to be female, be working, have more than a high school diploma, have private insurance, and need a caregiver compared to those who do not receive regular dental care. In addition, these participants were more likely to have had pneumonia since their SCI and have had a urinary tract infection in the past year and since injury.

Conclusion

More data on oral health are needed to make conclusions about the impact of oral health on secondary conditions and quality of life in people with SCI.
O uso da água na agricultura em Portugal - parte I - evolução da agricultura de regadio; aspetos sociais e institucionais
Authors: Duarte António
Published: August 2023

Nas condições climáticas de Portugal, a agricultura de regadio tem uma importância indiscutível na estrutura da produção final agrária, já que permite fazer culturas com maior valor acrescentado que as tradicionais culturas de sequeiro. Pretende-se neste estudo fazer uma abordagem integrada da questão do uso da água na atividade agrícola, enquadrada nos constrangimentos e oportunidades de cariz social e institucional. No último meio século constatou-se um significativo aumento da eficiência no uso da água na agricultura, a que tem correspondido um elevado consumo de energia. Dos aproveitamentos hidroagrícolas estudados, constata-se uma grande diversidade de esquemas de tarifação da água de rega, podendo o seu custo variar entre 77,4 e 556,8 €/ha para a cultura do milho. Note-se ainda que o custo da água de rega é, compreensivelmente, um fator que influencia, mas que não é determinante na taxa de adesão ao regadio. A taxa de adesão ao regadio dos aproveitamentos hidroagrícolas nacionais está condicionada por constrangimentos de natureza vária a que importa dar solução, ao mesmo tempo que devem ser promovidas medidas de incentivo.

Este texto analisa o processo de desenvolvimento profissional docente de professores no Brasil e Portugal. Tem como problemática: Quais características estão presentes na Comunidade de Prática (CoP) para se transformar em Comunidade Aprendente (CA) e potencializar o desenvolvimento profissional do professor/formador? A proposta é desenvolver e investigar um processo de criação de uma CoP (estudo de caso), por meio de um espaço de interação presencial e no ciberespaço que propicie o Desenvolvimento Profissional Docente a partir de estudos, discussões, reflexões e produções escritas referentes a concepções, experiências e saberes partilhados porporcionando a transformação em CA. Os áudios das reuniões presenciais serão transcritos e as postagens no ciberespaço facilitarão a análise. Para análise dos dados, realizaremos o acompanhamento e sistematização dos estudos por meio da análise textual discursiva para produzir categorias de saberes docentes vivenciados no processo interativo. O texto parte de um referencial teórico sobre o processo de criação de CoP e a transformação em CA. Em seguida, é apresentada uma experiência realizada no Instituto Federal de Educação, Ciência e Tecnologia Farroupilha (IFFAR) - Brasil, que proporcionou a transformação em CA. Por fim, é descrita a comunidade de prática em Portugal com características que potencializam a transformação em CA
Esquizofrenia: (dis)funções cognitivas e implicações biopsicossociais
Authors: Barbosa Maria , Machado Susana
Published: August 2023

O interesse científico acerca dos défices cognitivos associados à esquizofrenia aliado ao seu impacto na qualidade de vida dos indivíduos resulta na motivação para o desenvolvimento deste artigo. Objetiva-se: rever o percurso de concetualização da esquizofrenia; caraterizar as funções cognitivas no contexto da expressão desta psicopatologia; rever a literatura mais relevante relacionada com o estudo da atenção (considerada como uma disfunção cognitiva central) e explorar as implicações biopsicossociais da expressão das disfunções cognitivas na esquizofrenia. De forma a atingir os objetivos delineados realizou-se a análise, organização e operacionalização de informação baseada numa pesquisa webgráfica efetivada através do auxílio a diversas bases de dados (Web of science; Scielo; B-on), onde através da junção de operadores entre as palavras-chave se realizaram diversas equações de pesquisa. Foi dada maior preponderância e prioridade aos artigos com menos de sete anos. São indubitáveis as evidências empíricas que permitem sustentar uma relação de causalidade entre as disfunções ao nível cognitivo e uma influência transversal no que respeita à capacidade funcional das pessoas com esquizofrenia. Salientam-se, o desafio na aquisição de novas competências, na adaptação do indivíduo ao contexto e no comportamento social e ocupacional competente. Estas implicações de caráter biopsicossocial traduzem-se num impacto sobre o bem-estar e sobre a qualidade de vida destas pessoas.
