Late neolithic cultural landscape in the Al-Jafr Basin, southern Jordan: a brief review in context

The Late Neolithic cultural landscape in southern Jordan waspoorly understood due to the deficiency of basic information. However, recent investigations are improving this situation. A good example is providedby the discovery of a Jericho IX pottery assemblage at Munqata’a near Tafileh, which offers a glimpse into the influence of an exotic culture onthe post-PPNB cultural landscape in southern Jordan. However, things are different in the al-Jafr Basin to the east, where a new adaptation strategy to cope with increasing aridification was sought within the context of the traditional PPNB outpost culture. The difference in cultural landscapes between the east and the west in this period ushers in the era of ‘the desertand the sown.’ In preparation for future comparative study, this paper briefly reviews past research outcomes in the basin and discusses the Late Neolithic cultural landscape at the arid margin of southern Jordan.

Tomb architecture and distribution in the Eastern Necropolis of Nea Paphos, Cyprus

The Eastern necropolis of Nea Paphos is one of the most significant funerary landscapes of Cyprus, primarily because of its connection with the capital of the island during the Hellenistic and Roman times, and therefore of importance for the archaeology of the Eastern Mediterranean. The first systematic exploration of the site took place in the 1980s in the form of rescue excavations. Only limited research has been undertaken since then. This article discusses the necropolis based on unpublished material from the rescue excavations. It presents the tombs’ architecture; partially reconstructs the burial ground; reveals the extension of the necropolis; triggers questions related to the dynamics between nearby necropolis, and its potential correlation to satellite habitation sites.

Integer Programming, Constraint Programming, and Hybrid Decomposition Approaches to Discretizable Distance Geometry Problems
Authors: MacNeil Moira , Bodur Merve
Published: March 2021

Given an integer dimension K and a simple, undirected graph G with positive edge weights, the Distance Geometry Problem (DGP) aims to find a realization function mapping each vertex to a coordinate in [Formula: see text] such that the distance between pairs of vertex coordinates is equal to the corresponding edge weights in G. The so-called discretization assumptions reduce the search space of the realization to a finite discrete one, which can be explored via the branch-and-prune (BP) algorithm. Given a discretization vertex order in G, the BP algorithm constructs a binary tree where the nodes at a layer provide all possible coordinates of the vertex corresponding to that layer. The focus of this paper is on finding optimal BP trees for a class of discretizable DGPs. More specifically, we aim to find a discretization vertex order in G that yields a BP tree with the least number of branches. We propose an integer programming formulation and three constraint programming formulations that all significantly outperform the state-of-the-art cutting-plane algorithm for this problem. Moreover, motivated by the difficulty in solving instances with a large and low-density input graph, we develop two hybrid decomposition algorithms, strengthened by a set of valid inequalities, which further improve the solvability of the problem.

Summary of Contribution: We present a new model to solve a combinatorial optimization problem on graphs, MIN DOUBLE, which comes from the highly active area of distance geometry and has applications in a wide variety of fields. We use integer programming (IP) and present the first constraint programming (CP) models and hybrid decomposition methods, implemented as a branch-and-cut procedure, for MIN DOUBLE. Through an extensive computational study, we show that our approaches advance the state of the art for MIN DOUBLE. We accomplish this by not only combining generic techniques from IP and CP but also exploring the structure of the problem in developing valid inequalities and variable fixing rules. Our methods significantly improve the solvability of MIN DOUBLE, which we believe can also provide insights for tackling other problem classes and applications.
Robust Mixed 0-1 Programming and Submodularity
Authors: Joung Seulgi , Park Sungsoo
Published: March 2021

The paper studies a robust mixed integer program with a single unrestricted continuous variable. The purpose of the paper is the polyhedral study of the robust solution set using submodularity. A submodular function is a set function with a diminishing returns property, and little work has been studied on the utilization of submodularity in the study of optimization problems considering data uncertainty. In this paper, we propose valid inequalities using submodularity. Valid inequalities for the robust mixed integer program are defined. A polynomial separation algorithm is proposed, and we show that the convex hull of the problem can be completely described using the proposed inequalities. In computational tests, we showed the proposed cuts are effective when they are applied to general robust discrete optimization problems with one or multiple constraints.
Congruence Between Leadership Gender and Organizational Claims Affects the Gender Composition of the Applicant Pool: Field Experimental Evidence
Authors: Abraham Mabel , Burbano Vanessa
Published: March 2021

The extent to which men and women sort into different jobs and organizations—namely, gender differences in supply-side labor market processes—is a key determinant of workplace gender composition. This study draws on theories of congruence to uncover a unique organization-level driver of gender differences in job seekers’ behavior. We first argue and show that congruence between leadership gender and organizational claims is a key mechanism that drives job seekers’ interest. Specifically, many organizational claims are gender-typed, such that social claims activate the female stereotype, whereas business claims activate the male stereotype. Thus, whereas female-led organizations making social claims are gender-congruent, male-led firms making the same claims are gender-incongruent. Beyond demonstrating a general preference among job seekers for congruence, we also find that female job seekers are most interested in working for organizations that are simultaneously congruent and provide credible signals that they are fair and equitable employers. The congruence of leadership gender and organizational claims thus affects the gender composition of applicant pools for otherwise identical jobs.
Clinical impact of a sub-epidermal moisture scanner: what is the real-world use?
Authors: Musa Louisa , Ore Nicky , Raine Gillian , Smith Glenn
Published: March 2021

Objective:

The presence of sub-epidermal moisture (SEM) over a bony prominence is indicative of incipient pressure ulcer (pressure injury/decubitus/bedsore) (PU). Early identification of patients at increased risk of PU can prompt interventions that reduce the incidence and severity of hospital (or community)-acquired PUs (HAPUs). This study evaluated the clinical utility of a SEM Scanner device in HAPU management.

Method:

The study used a pragmatic ‘real-world’ approach. HAPU data before and during SEM Scanner use were obtained through routine audit. Patients had regular visual and daily SEM Scanner skin assessments over the sacrum and heels. Nursing care otherwise followed standard of care according to the established protocols of individual participating sites. HAPU incidence rates were determined and feedback gathered from health professionals on how the device influenced HAPU-related clinical decision-making.

Results:

There were 15 participating sites: 13 acute care, one palliative care and one community care setting. The sample size was 1478 patients. All sites reported a substantial reduction in mean HAPU incidence: 87.2% in acute care settings; 46.7% in the palliative care setting and 26.7% in the community care setting. A 100% incidence reduction was reported in 10 (66.7%) sites. In the palliative care setting, SEM Scanner results changed HAPU-related clinical decision-making for 40% of patients scanned. The community care site demonstrated a 82% change in clinical decision-making.

Conclusion:

In this study, SEM analysis fitted seamlessly into routine skin assessment and enabled early identification of increased risk of tissue damage, with clinically important reductions in the incidence of HAPU across all participating sites.
Functional limitations caused by simple bone cysts
Authors: Behman Amy , Feldman Brian , Doria Andrea , Fusco Caroline , Wright James
Published: March 2021

Purpose

Relatively little is known about the impact of benign bone lesions on function. The aim of this study was to create a more complete understanding of the impact of functional disability from simple bone cysts (SBCs) by combining qualitative and quantitative methods.

Methods

This study followed a convergent parallel mixed methods design. The quantitative arm included 130 children with SBC and used the Activities Scale for Kids (ASK) to measure physical function. In the qualitative arm ten children and their parents participated in interviews related to activity participation and interactions with their physical and social environments. The two data sets were analyzed independently and then the results were integrated.

Results

The ASK demonstrated 35% of children achieving the maximum score. In total, 65% of children responded “I had no medical needs” confirming that SBC, while being present throughout childhood, is largely perceived as not a chronic illness. Qualitatively most children reported minimal or no changes in activity participation but reported thinking about being more cautious during play, confirming that SBC affects effort not participation in play.

Conclusion

The diagnosis of SBC did not have a significant impact on physical function, but did alter children's thoughts about physical activity participation. This finding suggests that physical function scores may have unappreciated ceiling effects. Outcome tools that combine both illness perceptions and physical function may help to better assess functional outcomes of SBC.

Snapshot temporal compressive microscopy using an iterative algorithm with untrained neural networks
Authors: Qiao Mu , Liu Xuan , Yuan Xin
Published: March 2021

We report a snapshot temporal compressive microscopy imaging system, using the idea of video compressive sensing, to capture high-speed microscopic scenes with a low-speed camera. An untrained deep neural network is used in our iterative inversion algorithm to reconstruct 20 high-speed video frames from a single compressed measurement. Specifically, using a camera working at 50 frames per second (fps) to capture the measurement, we can recover videos at 1000 fps. Our deep neural network is embedded in the inversion algorithm, and its parameters are learned simultaneously with the reconstruction.
Diagnostic test accuracy for detecting Schistosoma japonicum and S. mekongi in humans: A systematic review and meta-analysis
Authors: Rahman Md. Obaidur , Sassa Miho , Parvin Natasha , Islam Md. Rashedul , Yajima Aya , Ota Erika
Published: March 2021

Background

Most of national schistosomiasis elimination programmes in Asia are relying on stool examination, particularly Kato Katz stool examination technique for regular transmission monitoring. However, the Kato-Katz technique has shown low sensitivity for the detection of light-intensity infections, and therefore highly sensitive diagnostic tools are urgently required to monitor prevalence of infection in low transmission settings. The objective of this systematic review was to evaluate and synthesize the performance of diagnostic tests for detecting Schistosoma japonicum and S. mekongi infection in people living in endemic areas.

Methodology/Principal findings

We comprehensively searched these nine electronic databases and other resources until July 2019, with no language or publication limits: PubMed, EMBASE, MEDLINE, Web of Science, BIOSIS Citation Index, HTA, CINAHL PLUS, The Cochrane Library, and PsycINFO. We included original studies that assessed diagnostic performance using antibody, antigen, and molecular tests with stool examination test as a reference standard. Two reviewers independently extracted a standard set of data and assessed study quality. We estimated the pooled estimates of sensitivity and specificity for each index test. We used diagnostic odds ratio to determine the overall accuracy and hierarchical summary receiver operating characteristics (HSROC) curve to assess the index tests performance.

Fifteen studies (S. japonicum [n = 13] and S. mekongi [n = 2]) testing 15,303 participants were included in the review. Five studies reported performance of enzyme-linked immunosorbent assay (ELISA), seven studies reported indirect hemagglutination assay (IHA), and four studies reported polymerase chain reaction (PCR) for detecting S. japonicum. The pooled sensitivity and specificity were 0.93 (95% CI: 0.84–0.98) and 0.40 (95% CI: 0.29–0.53) for ELISA, 0.97 (95% CI: 0.90–0.99) and 0.66 (95% CI: 0.58–0.73) for IHA, and 0.89 (95% CI: 0.71–0.96) and 0.49 (95% CI: 0.29–0.69) for PCR respectively. A global summary indicated the best performance for IHA, closely followed by ELISA. We were unable to perform meta-analysis for S. mekongi due to insufficient number of studies.

Conclusions/Significance

IHA showed the highest detection accuracy for S. japonicum. Further studies are needed to determine the suitable diagnostic methods to verify the absence of transmission of S. mekongi and also to compare detection accuracy against more sensitive reference standards such as PCR.
Lumenato protects normal human dermal fibroblasts from neutrophil-induced collagen-3 damage in co-cultures
Authors: Solomonov Yulia , Hadad Nurit , Pikovsky Oleg , Levy Rachel
Published: March 2021

Collagen is the major structural protein in the extracellular matrix of skin produced by fibroblasts. UV exposure results in infiltration of neutrophils within the epidermis and dermis, inducing collagen damage and contributing to the process of photo-aging. Collagen-3 is an integral structural component with collagen-1, and is an important regulator of collagen-1 fibrillogenesis. Addition of neutrophils activated with TNFα to normal human dermal fibroblast cultures, but not their supernatant, caused significant collagen-3 damage. To study whether Lumenato can protect from collagen-3 damage, it was added to co-cultures of Normal human dermal fibroblasts and neutrophils activated with TNFα. Lumenato prevented collagen-3 damage induced by activated neutrophils in a dose-dependent manner in the co-cultures. Lumenato also induced a low rate of collagen-3 synthesis in a dose-dependent manner detected by pro-collagen-3 secretion, but did not affect fibroblast cell number. Although Lumenato inhibited MMP-8, MMP-9, and elastase secreted from neutrophils, its main effect was in inhibiting both NADPH oxidase-producing superoxides and MPO activity-producing halides in a dose-dependent manner that correlated with protection from collagen-3 damage. In conclusion, the results suggest that Lumenato induces low levels of collagen-3 that may contribute for skin health and is very effective in defending the co-cultures from collagen-3 damage by inhibiting free radicals secreted from neutrophils, thus, indicating Lumenato's possible potential for skin protection.
Does living close to a petrochemical complex increase the adverse psychological effects of the COVID-19 lockdown?

Published: March 2021

The petrochemical industry has made the economic development of many local communities possible, increasing employment opportunities and generating a complex network of closely-related secondary industries. However, it is known that petrochemical industries emit air pollutants, which have been related to different negative effects on mental health. In addition, many people around the world are being exposed to highly stressful situations deriving from the COVID-19 pandemic and the lockdowns adopted by national and regional governments. The present study aims to analyse the possible differential effects on various psychological outcomes (stress, anxiety, depression and emotional regulation strategies) stemming from the COVID-19 pandemic and consequent lockdown experienced by individuals living near an important petrochemical complex and subjects living in other areas, nonexposed to the characteristic environmental pollutants emitted by these kinds of complex. The sample consisted of 1607 subjects who answered an ad hoc questionnaire on lockdown conditions, the Perceived Stress Scale (PSS), the Hospital Anxiety and Depression Scale (HADS), the Barratt Impulsivity Scale (BIS) and the Emotional Regulation Questionnaire (ERQ). The results indicate that people living closer to petrochemical complexes reported greater risk perception [K = 73.42, p < 0.001, with a medium size effect (η2 = 0.061)]. However, no significant relationship between psychological variables and proximity to the focus was detected when comparing people living near to or far away from a chemical/petrochemical complex. Regarding the adverse psychological effects of the first lockdown due to COVID-19 on the general population in Catalonia, we can conclude that the conditions included in this survey were mainly related to changes in the participants’ impulsivity levels, with different total impulsivity scores being obtained if they had minors in their care (p<0.001), if they had lost their jobs, if they were working (p<0.001), if they were not telecommuting (p<0.001), if they went out to work (p<0.001) or if they established routines (p = 0.009). However, we can also be fairly certain that the economic effects are going to be worse than those initially detected in this study. More research will be necessary to corroborate our results.
Effects of rumen-degradable-to-undegradable protein ratio in ruminant diet on in vitro digestibility, rumen fermentation, and microbial protein synthesis
Authors: Putri Ezi Masdia , Zain Mardiati , Warly Lili , Hermon Hermon
Published: March 2021

Background and Aim: Feeding ruminants must notice the degradability of feed, especially protein. Microbial rumen requires ammonia from rumen degradable protein (RDP) beside that ruminant require bypass protein or rumen undegradable protein (RUP) and microbial crude protein. The aim of the study was to discover the best RDP:RUP ratio in beef cattle diets commonly used by Indonesian farmers using an in vitro methodology.

Materials and Methods: Samples of Pennisetum purpureum, Leucaena leucocephala, Indigofera zollingeriana, cassava, maize, palm kernel cake, rice bran, and tofu waste were formulated into dietary treatments (dry matter [DM] basis). All experiments were carried out using a 3×3×2 factorial, randomized block design with three replications. Treatments consisted of three protein levels (12%, 14%, and 16%), two energy levels (65% and 70%), and three RDP:RUP ratio levels (55:45, 60:40, and 65:35). The experimental diets were incubated in vitro using buffered rumen fluid for 48 h at 39°C. After incubation, the supernatants were analyzed to determine pH, ammonia concentration, total volatile fatty acid (VFA), and microbial protein synthesis. The residues were analyzed to determine DM, organic matter, protein, and RUP digestibility.

Results: Increased protein, energy, and RDP levels increased digestibility, ammonia concentrations, total VFAs, and microbial protein synthesis (p<0.05), while rations with 16% protein lowered these parameters (p<0.05).

Conclusion: Increased dietary protein (from 12% to 14% DM), energy (from 65% to 70% DM), and RDP (from 55% to 65% crude protein [CP]) levels increased nutrient digestibility, ammonia concentration, total VFA levels, and microbial protein synthesis. The diet containing 14% DM dietary protein and 70% DM energy, which contained 55%, 60%, or 65% CP RDP optimally increased nutrient digestibility, ammonia concentration, total VFA levels, and microbial protein synthesis. Thus, feed based on these RDP:RUP ratios can optimize ruminant productivity.
Leadership characteristics that influence corporate efficiency
Authors: Kazai Ónodi Annamária , Répáczki Rita
Published: March 2021

Economic focus analysis alone cannot answer an organisation’s efficiency issues, as the soft attributes associated with management skills and leadership qualities are also important. According to transformational leadership theory (Bass–Avolio 1994, Bass 1990, Judge–Bono 2000, Bass–Bass 2008), there is a transformation between the manager and the subordinate, in which the two parties interact with and affect each other. A joint two-phase study was conducted to investigate the role of management in increasing corporate efficiency. As a first step, financial data of 1752 Hungarian manufacturing firms were analyzed. Companies were grouped according to their TFP (total factor productivity) (Juhász et al. 2020). As a second step, we linked a questionnaire survey to the preliminary TFP categorization. In our questionnaire research, we examined the individual characteristics, qualities, and specialties of leadership practices concerning the economic performance of the organizations. According to our findings, both the individual qualities of the leader and the characteristics of the leadership practice are decisive for the efficiency and results of the organization.
Effects of the Global Financial Crisis on the V4
Authors: Nagy Péter Artúr
Published: March 2021

The aim of the research is to explore the development of trade relations between the Visegrád countries and their major Western European partners since accession to the European Union. The topic is currently an important one, as the Visegrád region is highly dependent on Western European countries, especially in the area of foreign trade. The research analyzed how the 2008-2009 global economic crisis and the subsequent sovereign debt crisis in Europe affected these trade relationships, i.e. did it cause significant changes in levels of relationship and/or trends. To answer this question, this paper used a time-series analysis method called Interrupted Time Series Analysis. As a result, statistically significant changes in the level and trend of foreign trade relations between the Visegrád countries and their Western European partners were detected. Finally, a more detailed breakdown of product groups also revealed which product groups are most responsible for slowing down the growth of trade relations.

A jelenlegi uniós szabályozás célkitűzései között szerepel a postapiac liberalizációja, a verseny elősegítése, az egyetemes szolgáltatók mellett más piaci szereplők megjelenésének ösztönzése. A 2008-as III. postai irányelv értelmében a teljes piacnyitásban hazánkat 2012. december 31-ig derogáció illeti meg. E felkészülési időszakban az illetékes hatóságoknak a piac szabályozásában jelentős lépéseket kell tenniük. Az egyik legjelentősebb változtatás a közszolgáltatások kapcsán központi problémaként említhető egyetemes szolgáltatásokat érinti. E szolgáltatások vonatkozásában a hatályba lépő új irányelv a korábbiakhoz mérten szigorúbb, mindenki számára elérhető, meghatározott minőségű szolgáltatás nyújtására kötelezi az egyetemes szolgáltatókat, mely számukra jelentős többletterhet (többletköltséget) róhat. Jelen értekezés rövid áttekintést nyújt az európai uniós postapiaci szabályozás fontosabb aspektusairól, jellemzi a főbb, többletteher számítására kialakított modelleket, valamint bemutatja a hazai postapiac liberalizációjáig terjedő felkészülési időszak központi kérdésköreit.

A Base Nacional Comum Curricular e as formas de subjetivação do professor de Matemática
Authors: Fonseca Letiane Oliveira da , Fonseca Márcia Souza da , Quevedo Jaíne Telles , Correa Mônica Roxo
Published: March 2021

O artigo propõe um debate acerca das proposições da Base Nacional Comum Curricular (BNCC) e os seus impactos na formação de professores que ensinam Matemática. Para tanto, destaca-se como problemática: “Qual perfil de professor que ensina Matemática no ensino fundamental é desejado pela BNCC?”. A análise discursiva foi utilizada na compreensão das relações de poder que emergem do discurso da Base. No que concerne ao currículo, ao conhecimento escolar e às subjetivações, Apple (2001 e 2006) e Silva (1999) subsidiaram as discussões, possibilitando a percepção de que a BNCC, como documento norteador, sugere a Matemática como uma ciência humana — produzida por diferentes grupos sociais — contudo, apresenta um discurso hegemônico, priorizando certos saberes e competências.
Financiamento da Educação Básica no Brasil

Published: March 2021

Analisamos a estrutura da política de financiamento da Educação Básica no contexto da organização federativa do Estado brasileiro, de sua fundação à promulgação da Constituição Federal de 1988. A análise foi qualitativa. Concluímos que estados economicamente fortes tiveram maior poder de barganha frente aqueles com menos recursos, aprofundando as desigualdades regionais, culminando nos anos 1980/1990 em políticas governamentais organizadas em torno da regulação de “racionalidade democrática”, com dispersão de recursos, racionalidade financeira e redução de gastos públicos e tamanho do Estado.

Published: March 2021

O trabalho tem como objetivo apresentar um panorama das políticas curriculares para o ensino de Matemática realizado no ensino médio no período de 2010 a 2019 no Brasil, visto que essa modalidade de ensino é a que apresenta os menores índices de rendimento escolar apontado pelas avaliações externas. A pesquisa bibliográfica possibilitou um estado da arte de abordagem qualitativa. Os resultados acusaram concentração de produções sobre políticas curriculares para educação básica centradas no ensino fundamental, apontando carência de trabalhos nesse âmbito no ensino médio. Embora as produções evidenciassem a contribuição e a relevância da Matemática à educação, foi constatada a escassez de produções que relacionem as políticas curriculares e o ensino de Matemática, sobretudo no ensino médio.

O estudo investiga o movimento das matrículas da educação básica estadual e municipal em Roraima a partir da implementação do Fundeb no período de 2009/2019, considerando a dinâmica de divisão de responsabilidades entre as redes de ensino na oferta educacional. A pesquisa é de cunho qualitativo e documental, a partir das fontes de dados: Sistema de Informações sobre Orçamentos Públicos em Educação (Siope) e o Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep). As matrículas foram coletadas nas Sinopses Estatísticas da Educação Básica do Inep e no Laboratório de Dados Educacionais organizada por pesquisadores da Universidade Federal do Paraná (UFPR). Os dados financeiros foram coletados nos Relatórios Resumidos de Execução Orçamentária (RREO) estadual e municipal do Siope, no período de 2009 a 2019. Os resultados mostram redução das matrículas da educação básica na rede estadual de ensino e aumento destas na rede municipal, decorrente das transferências das matrículas da primeira para a segunda. No entanto, as etapas da educação básica apresentam um aumento positivo nas matrículas, isso se deve à inclusão destas na distribuição de recursos do Fundeb.

Published: March 2021

Este estudo tem por objetivo analisar as condições de efetividade do ensino em investimentos na educação básica dos municípios de Ananindeua e Marituba e suas condições de oferta e qualidade no contexto do FUNDEB. Trata-se de uma pesquisa exploratória dos indicadores de financiamento, de oferta educacional e de qualidade, a partir do método em educação comparada que procurou estabelecer relações entre as diferenças e semelhanças dos municípios pertencentes à região metropolitana de Belém-Pa. A análise dos dados revelou que, nenhum dos dois conseguiu atender totalmente as demandas de oferta com qualidade da educação básica, apesar do incremento de recursos por meio do FUNDEB. O que evidencia a necessidade de reestruturação da política de fundo e maior contribuição financeira da União.
Fundo de Manutenção e Desenvolvimento da Educação Básica e de valorização dos profissionais da educação (FUNDEB)
Authors: Conceição Sergio Henrique , Mota Júnior Antônio de Macêdo , Dourado Gilson Barbosa
Published: March 2021

O estudo de natureza exploratória-descritiva e documental, de abordagem quantitativa, investiga a execução do Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação (Fundeb), no período 2009-2019, no contexto de cinco municípios (Camaçari, Dias D’Ávila, Lauro de Freitas, Mata de São João e Simões Filho) da Região Metropolitana de Salvador (RMS). Os resultados obtidos indicaram que o Fundeb possibilitou ampliar o volume de recursos nos sistemas municipais de educação; entretanto, aspectos relacionados à demanda reprimida na educação infantil, indisponibilidade de recursos para manutenção e desenvolvimento do ensino (MDE) e o decréscimo nas matrículas na educação de jovens e adultos (EJA) configuram-se como desafios a serem superados.
Planos de Ações Articuladas 2007-2010, 2011-2014 e as ações financiáveis pela União na rede estadual de ensino do Rio Grande do Norte
Authors: França Magna , Morais Magnólia Margarida dos Santos
Published: March 2021

O trabalho objetiva conhecer o investimento de recursos pela União, considerado assistência financeira nos Planos de Ações Articuladas, dos períodos 2007-2010 e 2011-2015, concernentes à infraestrutura física e recursos pedagógicos da rede estadual de ensino do RN, na perspectiva do regime de colaboração. Tomou-se como referências, normas e documentos legais, bem como dados quantitativos financeiros extraídos de sites oficiais. Considerou-se o recebimento de uma quantia razoável de recursos, apresentados em forma de programados, empenhados e executados, via convênios e termos de compromissos. Porém, com as limitações burocráticas e legais, em nível da SEEC/RN e do MEC, ocorreram prejuízos no andamento das obras escolares, sendo 6 concluídas, 14 em execução e as demais correspondentes a 36 estão paralisadas, 2 canceladas e 2 em fase de contratação.

La importancia de la orientación vocacional antes y durante la formación profesional
Authors: López Selas Sonia
Published: March 2021

Las vocaciones pertenecen a las personas, no a las profesiones. Identificarlas y valorarlas en cada estudiante debería ser la base para la toma de decisiones en sus itinerarios formativos y profesionales. Los programas de orientación vocacional acompañan al alumnado en este proceso que conduce a elecciones más conscientes y, a la larga, genera profesionales más motivados.
Se trata de aprendizaje: formal, no formal, informal
Authors: García de Andrés Carmen , Serrano Almodóvar Ángel
Published: March 2021

El aprendizaje, entendido en su sentido más amplio como el desarrollo de competencias y destrezas de todo tipo (personales y académicas, técnicas, profesionales…) se produce en distintos contextos —formales, no formales, informales— y siempre con la premisa de la atención e interés de quien aprende. No hay dos personas iguales y, por tanto, no hay dos formas iguales de aprender. ¿Por qué nos empeñamos en enseñar de una manera estandarizada que, más allá de ordenar, ha creado un modelo encasillado y limitante para el alumno?
Formación Profesional Básica: la etapa educativa al servicio de la equidad
Authors: Martín de Soto Domínguez Julián
Published: March 2021

La Formación Profesional Básica es el lugar físico y en el sistema donde deben confluir lo educativo, lo social y lo laboral. No se puede abordar desde lo educativo una realidad que no es exclusivamente educativa. No se puede abordar desde lo formal una realidad que trasciende lo formal. Un problema sistémico —y este lo es— solo puede abordarse desde una perspectiva sistémica.

David Otero: La libertad es para utilizarla bien y “trabajarse como persona”
Authors: Padres y Maestros
Published: March 2021

En el mundo educativo es bueno tener los ojos bien abiertos. Mirar desde dentro y, por supuesto, desde fuera. Por este motivo presentamos en este artículo, la mirada de David Otero (Madrid, 1980) sobre la educación. David, conocido por muchos, es cantante, guitarrista, compositor y padre de dos hijos. Fue miembro del grupo de pop-rock El Canto del Loco (1994-2010). A partir de la disolución de uno de los grupos más importantes del panorama español, continuó su carrera en solitario como El Pescao. En la actualidad, y desde 2017, su música sigue muy vigente con discos como “David Otero”, “1980” y “Otero y yo”. Además, hace dos años, lanzó su primer libro Precipicio al mar (Aguilar, 2019). Nos complace contar con la mirada de David. Una mirada sensata, a veces tímida, sincera y espontánea.

Don Bosco y la formación profesional
Authors: Bartolomé Fernández Óscar
Published: March 2021

Don Bosco, guiado por un sueño e interpelado por la realidad que vivió en el Turín del siglo XIX, supo dar una respuesta educativa, desde su sistema preventivo, a las necesidades juveniles. La creación de los talleres y su preocupación por el mundo obrero harán que con el paso del tiempo la formación profesional sea una seña de identidad de los Salesianos y Juan Bosco se convierta en el patrón de la formación profesional en nuestro país.
Numéro 161 - mars 2021
Authors: Carpantier Jean-François
Published: March 2021

L’or est étroitement mêlé à l’histoire des hommes, étant tour à tour chair des dieux égyptiens, matière des premières pièces de monnaie, promesse de liberté lors des ruées vers l'or et ancrage du système monétaire international. Aujourd’hui, alors qu’il ne joue plus de rôle officiel dans nos systèmes monétaires, l’or continue de susciter l’intérêt des investisseurs.

En août 2020, le prix de l’or a atteint un nouveau sommet en dépassant ponctuellement les 2.000 dollars l’once. L’investissement est tentant. Les vertus présumées de l’or sont multiples. Certains y voient un refuge lorsque le climat économico-financier se dégrade, d’autres une couverture contre les fluctuations du dollar américain, d’autres un moyen de se protéger de l’inflation. Et justement, les craintes d'un retour de l'inflation ressurgissent, au vu des niveaux d'endettement de nos économies.

Dans ce numéro de Regards économiques, nous testons la validité de cette dernière vertu : la propriété qu'aurait l'or de protéger contre l’inflation. L’originalité de notre approche est non pas d’évaluer la capacité propre de l’or à préserver le pouvoir d’achat, mais plutôt sa performance relative par rapport à d’autres matières premières que sont, par exemple, le pétrole, le cuivre ou le blé. En nous appuyant sur différentes techniques statistiques, nous montrons que la réputation de l'or est surfaite, l'or n'étant pas plus apte à protéger contre l’inflation que ne l’est le maïs, le nickel, le pétrole ou toute autre matière première.
