Diritto alla vita, principi costituzionali ed interpretazione per valori
Authors: Calabrò Gian Pietro
Published: January 2021

L’Articolo intende mostrare il ruolo che il diritto alla vita, nella sua prospettiva assiologica, può svolgere all’interno dell’ordinamento giuridico delle democrazie costituzionali. Rilevato il nesso strettissimo tra diritto alla vita e nozione di persona, quest’ultima collocata al centro del sistema costituzionale, l’Autore, nello sviluppare alcune considerazioni di Antonio Baldassarre sulla necessità che il valore vita possa essere bilanciato da un eguale valore, sostiene la possibilità di istituire all’interno della c.d. interpretazione per valori, una gerarchia che abbia al vertice il diritto alla vita quale precondizione di ogni altro diritto. In questa prospettiva il diritto alla vita incide profondamente sullo stesso destino delle democrazie pluralistiche e ne diventa il principio della loro legittimazione.

In altri termini, conclude l’Autore, il diritto alla vita può essere inteso come la Grundnorm senza, però, essere assunta in modo ipotetico e convenzionale secondo lo schema kelseniano, qualificando sul piano giuridico ed etico l’intero ordinamento.
Medicina veritatis: The Multi-Faceted Relationship between Truth and Medicine
Authors: Woodall George John
Published: January 2021

Il lavoro cerca di valutare il rapporto tra la verità e la medicina. Parte dal riconoscimento dell’importanza fondamentale della verità e della veracità nella tradizione cristiana e nella promozione della dignità umana e nello sviluppo della società più generalmente. Il dibattito in seno alla teologia morale cattolica circa la veridicità in casi di conflitto fornisce il retroscena per l’analisi della responsabilità del personale medico, dei parenti e degli altri per la comunicazione della verità al paziente. La veridicità appare quale realtà pluri-dimensionale, che tocca tutte le sfere dell’attività medica e della ricerca scientifica in campo medico. In questo contesto si dà un’attenzione esplicita alla ricerca clinica. La scelta di focalizzare sull’oncologia scaturisce dalla percezione pastorale che tante vite umane ammalano di tumore ed anche il fatto che le questioni morali in gioco emergono più chiaramente una volta che si tratti di patologie potenzialmente letali. I contributi principali del testo sarebbero la dimostrazione della multiforme maniera in cui la verità e la veracità influiscono e dovrebbero influire sulla medicina e sostenere che la verità stessa funge da medicina al livello intrapersonale, interpersonale e trascendentale della vita umana dolente.

Il trapianto di organi nella prospettiva valoriale del dono
Authors: Cozzoli Mauro
Published: January 2021

La chirurgia dei trapianti e la legge di una regolazione giuridica devono rispondere a una logica del dono. Questa pratica medica, infatti, si compie nel contesto di una relazione umana tra il soggetto dell'espianto e il soggetto dell'impianto. L'indole interpersonale dell'evento richiede che il rapporto sia da donatore a beneficiario, che sia cioè riconosciuta e tutelata la natura del dono dei tessuti e organi da trapianto.

Si configura così un'etica del dono. Come esigenza etica la gratuità è sotto l'istanza del dovere e della responsabilità. Ovviamente nessuno può costringere a donare. Il dono non è coercibile: si annullerebbe come dono. Ma anche il dono esprime un dovere: non il dovere della legge ma dell'amore/carità, che ci lega al prossimo come nostro “fratello” nell'“economia” della paternità universale divina.

Da qui l'invito che l'autore muove a tutti gli operatori sanitari ad annunciare e testimoniare questa etica del dono che ha nella medicina dei trapianti un campo inedito e singolare di promozione oggi di “qualità della vita”, della vita tout court.

L'etica del dono non solo non contrasta ma appella essa stessa un ordine legale che la supporti e la favorisca. Una legalità che offra la possibilità effettiva a tutti, attraverso un'organica azione di informazione e formazione, di fare la propria scelta e di esprimerla, e che si faccia giuridicamente garante delle esigenze e della vita del donatore anche in merito al “consenso presunto”.
Contro la fecondazione eterologa
Authors: Fiori Angelo
Published: January 2021

Il processo di progressiva accettazione della fecondazione eterologa può indurre gli oppositori ad abbandonare le proprie posizioni prendendo atto della loro sostanziale inutilità ed accettando di fatto il principio secondo cui i prodotti del progresso devono essere disponibili a tutti coloro che desiderano fruirne.

Per contro, l’autore ritiene che la fecondazione assistita nel suo insieme, non solo la fecondazione eterologa con i suoi peculiari problemi, comincia a presentare nel suo contesto crepe che ora si tenta di occultare, ma che sono destinate a minare in tempo abbastanza breve certezze finora presentate nei consueti termini del trionfalismo biomedico.

Molti sono infatti i problemi, scientifici ed etici, che essa solleva: la natura del trattamento di fecondazione eterologa, i rischi per la madre e per il feto, l’anonimato per il donatore e i rischi di approdo alla selezione eugenetica a seguito dei progressi della genetica molecolare, i diritti dei figli, la crioconservazione degli embrioni soprannumerari e l’ipotesi della “donazione di embrione”.

Oggi non è possibile prevedere quale sarà il destino delle pratiche di fecondazione assistita, particolarmente della fecondazione eterologa. Tuttavia, a medio termine l’autore si sente di prevedere il loro declino e la loro futura scomparsa a causa dell’aggrovigliarsi progressivo dei problemi che essa implica.

Massimo deve essere l’apprezzamento del desiderio di avere un figlio, sono infatti le leggi biologiche che ispirano con la loro forza questi potenti desideri; ma la fecondazione eterologa da padre anonimo non è la risposta a queste speranze. Altre sono le strade.
Mitral kissing lesion with anterior mitral leaflet aneurysm in a child
Authors: Raja Javid , Ponnuru Srawanthi , Dharan Baiju S , Suneel PR
Published: January 2021

Aortic valve endocarditis can lead to secondary involvement of aorto mitral curtain and the adjacent anterior mitral leaflet (AML). The secondary damage to AML is often caused by the infected diastolic jet of aortic regurgitation hitting the ventricular surface of the anterior mitral leaflet, or by the pronounced bacterial vegetation that prolapses from the aortic valve into the left ventricular outflow tract. This is called “kissing lesion”. We describe a case of infective endocarditis of aortic valve in a 13-year-old child causing secondary mitral valve involvement with AML perforation and aneurysm formation.

The pulmonary artery catheter (PAC) and its role in the practice of modern medicine remains to be questioned and has experienced a substantial decline in its use in the most recent decades. The complications associated to its use, the lack of consistency of the interpretation provided by the PAC among clinicians, the development of new hemodynamic methods, and the deleterious cost profile associated to the PAC are some of the reasons behind the decrease in its use. Since its introduction into clinical practice, the PAC and the data obtained from its use became paramount in the management of critically ill patients as well as for the high-risk/invasive procedures. Initially, many clinicians were under the impression that regardless the clinical setting, acquiring the information provided by the PAC justified its use, until a growing body of evidence demonstrated its lack of mortality and morbidity improvement, as well as several reports of the presence of difficulties—some of them fatal—during its insertion. The authors present an updated review discussing the futility of the PAC in current clinical practice, the complications associated to its insertion, the lack of mortality benefit in critically ill patients and cardiac surgery, as well as present alternative hemodynamic methods to the PAC.
Diagnostic challenges with transesophageal echocardiography for intraoperative iatrogenic aortic dissection
Authors: Rhoades Daniel , Subramani Sudhakar
Published: January 2021

Iatrogenic aortic dissection is a rare and serious complication of cardiac surgery with an incidence between 0.12% and 0.16%. Dissections involving an intimal flap can be detected using trans-esophageal echocardiography (TEE) with a sensitivity of 94%–100% and specificity of 77%–100%. Rarely, dissections can occur that are not detectable by TEE. There have been reports of iatrogenic dissection in the ascending aortic cannulation site; however, a dissection at the antegrade cardioplegia cannulation site is very rare. It also presents challenges associated with early diagnosis and appropriate intervention. We are describing a rare case of aortic dissection at the antegrade cardioplegia cannulation site in the proximal ascending aorta. The dissection was unable to be visualized with TEE initially, and required epi-aortic ultrasound to diagnose dissection in timely manner.
Automotive Refrigerant Air-Conditioning Hose Requirements
Authors:   Interior Climate Control MAC Supplier Committee
Published: January 2021

The scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between the user and supplier.

Requirements for the hose used in coupled automotive refrigerant air-conditioning assemblies are included in SAE J2064. SAE J3062 separates requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary refrigerant permeation values used in SAE J2727. Mobile air-conditioning system refrigerant emissions rates are established in SAE J2727 emission charts and are important. The certified coupling of MAC hose assemblies is required in meeting certain regulatory requirements.

Therefore, the scope of SAE J2064 has been changed to establish the assembly requirements for factory and field coupled hose assemblies. A hose which meets the requirements of SAE J3062 may not meet the requirements of SAE J2064. Bulk hose produced prior to the release of this standard could be labeled “SAE J2064” and may not meet the requirements of SAE J3062.

Published: January 2021

Base drag is arising from flow separation at blunt base of a body. It can be a sizeable fraction of total drag in context of projectiles, missiles and after bodies of fighter aircrafts. The base drag is the major contribution of total drag for low speed regimes, flight tests have shown that the base drag may account for up to 50% of total drag. In this paper an experimental investigation for simple semi-circular flight vehicle body of length 500mm and diameter 50mm was conducted for the purpose of investigating base drag. The base drags for three configurations are calculated and the results are compared with CFD data. The three configurations used for testing are flat base configuration, closed nozzle configuration and boat tail configuration. The evaluation of base drag for three different flow velocities such as (i) 20m/s, (ii) 35m/s and (iii) 50m/s at different angle of attack such as -2ï‚°, 0ï‚° and 2ï‚° are experimented and compared.

Published: January 2021

In this paper, a linear two degrees of freedom linear bicycle model is proposed to investigate the vehicle handling criterion. The study is based on simulation developed using MATLAB / Simulink to predict the vehicle dynamic stability. Steering angle is given as an input to the mathematical model for various vehicular manoeuvres. This model is validated using a step input which is adjusted to give 0.3g lateral acceleration. The system model is simulated under a typical front wheel steering to examine the highway vehicle prediction output within its manoeuvre. This input is also adjusted to keep lateral acceleration value in steady state region. It is found that changing the vehicle center of gravity (CG) position, vehicle mass, tire cornering stiffness and vehicle speed all have a significant influence on the vehicle dynamic stability.
Teachers competencies in evaluation of competency based curriculum among special needs learners in Kenya
Authors: Andiema Nelly C.
Published: January 2021

Assessment and evaluation activities are conducted to determine whether the curriculum content provided to students resulted to gain of knowledge and understanding. With the Kenya implementing the new Competency Based Curriculum (CBC), not much has been focused on the level of teacher understanding and preparedness towards evaluating special needs learners enrolled in public primary schools. This paper looks at teacher competencies for evaluation of CBC among special needs learners in public primary schools in Kapsaret Sub County, Kenya. The target population involved 83 public primary schools located in the sub county with special needs teachers of the targeted primary schools forming the target population. A sample size of 69 special needs teachers was selected as the sample for the study selected through simple random sampling method. To collect data, questionnaire was used. The analysis of data was done using quantitative and qualitative methods. Research result showed that majority of special needs teachers were not adequately prepared to undertake evaluation and assessment of children with special needs in line with the new curriculum. The lack of adequate understanding and application of formative assessment methods by special needs teachers denied the special needs learners opportunity to acquired competencies and skills as per CBC curriculum. The paper therefore recommends that special needs teachers like other teachers need to be regularly provided with adequate training on different methods of assessment of special needs learners in their classroom. This will ensure that the goals of inclusion are attained hence contributing to special needs learners education growth and development.

Published: January 2021

En zone soudano-sahélienne, la productivité des cultures est limitée par les effets néfastes du changement climatique et la pauvreté des sols. L’insertion des plantes de couverture dans les systèmes de production pourrait être une alternative d’amélioration des rendements et de la biomasse. Pour atteindre cet objectif, la pratique conventionnelle de la culture du maïs a été comparée pendant cinq années (2014-2018), à quatre systèmes de culture associant des plantes de couverture. Le dispositif expérimental utilisé a été un bloc de Fisher avec 6 traitements en 4 répétitions. Les résultats ont montré que l’insertion du Cajanus cajan, du Stylosanthes hamata, du Brachiaria ruziziensis et Mucuna cochinchinensis dans un système de culture à base du maïs permet d’améliorer la production de biomasse fourragère sans négativement affecter son rendement. Utilisée dans la supplémentation des animaux, la biomasse produite peut nourrir pendant 90 jours 7 unités de bétail tropical (UBT) en culture pure du maïs et 8 à 13 unités de bétail tropical (UBT) en fonction du type de plantes de couverture. Dans le cadre de la production fumure organique, les mêmes tendances de variations ont été obtenues en fonction des systèmes de culture. L’insertion des plantes de couverture est un élément intégrateur agriculture-élevage.Mots clés : Changement climatique, maïs, légumineuse, biomasse fourragère, zone Soudano-sahélienne, Mali

 

English Title: Cover crop insertion effect on productivity of maize-based cropping system in the context of crop-livestock integrationIn Sudano-Sahelian zone, crop productivity is limited by climate change effect and poor soils. Inserting cover crops into production systems could be an alternative to improve yields and biomass. To achieve this goal, conventional practice of maize cultivation was compared over a five-year period (2014-2018) with four cropping systems using cover crops. The experimental design used was a Fisher block with 6 treatments in 4 replicates. The results showed that the insertion of Cajanus cajan, Stylosanthes hamata, Brachiaria ruziziensis and Mucuna cochinchinensis in a maize-based cropping system improves biomass production without negatively affecting its yield. Used in animal supplementation, the biomass produced can feed 7 Tropical Livestock Units (UBT) of pure maize crop and 8 to 13 UBT for 90 days, depending on the type of cover crop. In the case of organic manure production, the same variations were obtained depending on cropping systems. The insertion of cover crops in cropping system is an integrating agriculture-livestock component.Keywords: Climate change, maize, legumes, fodder biomass, fodder biomass, Sudano-Sahelian zone, Mali.
Cocoa husks: a sustainable resource for alkali production
Authors: Maliki M. , Ifijen I.H. , Omorogbe S.O.
Published: January 2021

Nigeria has no commercial alkali plant and most of her alkali requirements are imported. Thus the sustainability of using cocoa husks as resource for alkali production was investigated. Cocoa husks collected from three locations in Edo State; (CH1), (CH2) and (CH3) were separately burnt to ashes. Moisture content of ashes ranged from 72.25 ± 1.92% to 74.75 ± 4.11%, dry matter from 25.26 ± 4.11% to 27.76± 1.92 %, while ash content ranged from 20.29 ± 3.00% to 23.01 ± 3.71%. Alkali was extracted from the ashes by leaching with water at room temperature and CH1 had highest alkaline content (0.84± 0.01 M) while CH2 had the lowest (0.78± 0.02 M). Conductivity of the extract was 72.45± 0.03 s/m, 71.02± 0.02 s/m and 71.64± 0.01 s/m, while the pH was 11.655± 0.02 s/m, 11.40± 0.01 s/m and 11.42 ± 0.02 s/m respectively for CH1 CH2 and CH3. Metal analysis revealed that they contain appreciable potassium (CH1 = 43.54%, CH2= 41.15% and CH3= 41.67%) and sodium (CH1 = 34.78%, CH2 = 37.55% and CH3 = 34.86%) ions, thus can be used to generate alkali as alternative to foreign alkali, reduce Nigerian dependence on foreign alkali and providing environmental solution to their disposal problem.Keywords: Potassium, sodium, ash extract, wastes

L’objectif de cette étude était, de comparer six méthodes de dosage indirect du cholestérol LDL en vue de mettre en place une méthode plus pertinente dans le suivi des modifications cardiométaboliques chez les personnes vivant avec le VIH (PVVIH) sous traitements. Il s’agissait d’une étude prospective descriptive et analytique chez des PVVIH sous antirétroviraux à Libreville, allant du 13 août au 30 novembre 2018. Les patients de plus de 15 ans ont été inclus après avoir donné leurs consentements. Le dosage du cholestérol total, cholestérol HDL, cholestérol LDL et triglycérides a requis un automate multi analyseur (BS 200 de Mindray®) ainsi que des kits « BIOLABO ». La régression linéaire était utilisée pour rechercher les différentes corrélations. Les valeurs de triglycérides <150mg/dL étaient retrouvées chez 96% de la population et 52% avait une concentration de cholestérol HDL <40mg/dL. Les différentes formules de calcul de la concentration du cholestérol LDL par rapport aux  concentrations de LDL cholestérol direct ont montré que le carré du coefficient de corrélation linéaire r était plus élevé pour la formule  d’Anandaraja (r2 = 0,83), suivi de celle de Friedewald avec r2 = 0,72. Un palliatif au dosage direct pourrait être l’utilisation de la formule d’Anandaraja dans notre contexte d’étude.Mots clés : Cholestérol LDL, Cholestérol total, Méthode indirecte, VIH, Anandaraja, Friedewald. Comparison of six indirect LDL cholesterol methods among HIV patients in Libreville

 

The objective of this study was to compare six methods of indirect measurement of LDL cholesterol for setting a more relevant method of monitoring cardiometabolic changes in people living with HIV under treatment. This was a prospective descriptive and analytic study among people living with HIV and under antiretroviral therapy in Libreville, from 13 August to 30 November 2018. Patients over 15 years of age were included after giving their consent. The dosage total of cholesterol, HDL cholesterol, LDL cholesterol and triglycerides required a multi analyzer BS 200 of Mindray® and reagents kits from BIOLABO. Linear regression was used to found different correlations. Triglyceride values below 150 mg/dL were found among 96% of the population and 52% had HDL cholesterol concentration below 40 mg/dL. The different formulas for calculating the LDL cholesterol concentration relative to the direct LDL cholesterol concentrations show that the square of the linear correlation coefficient r is higher for the Anandaraja formula (r2 = 0.83) followed by that of Friedewald with r2 = 0.72. A palliative method to the direct assay could be the use of Anandaraja's formula in our context.Keywords: LDL cholesterol, Total cholesterol, Indirect method, HIV, Anandaraja, Friedewald.

Correlations between chemical composition, enzymatic hydrolysate gross energy (EHGE), and true metabolizable energy (TME) of corn for ducks were investigated. Twenty-two corn samples were collected from various regions in 11 provinces of China. The crude protein (CP), ether extract (EE), neutral detergent fibre (NDF), Ash, gross energy (GE), dry matter (DM), amylopectin (AP), amylose (AM), total starch (TS), and AP/AM were determined for each sample. Five of the samples of corn were chosen at the mean, mean ± 1 standard deviation (SD), and mean ± 2 SD based on AP/AM. The EHGE of these samples was analysed using the pepsin-artificial small intestinal fluid enzymatic method. These five samples were also force-fed to male Cherry Valley ducks to assay their TME. Finally, correlation analyses were performed, and regression equations were established. Ash content, GE, and TS were highly related to EHGE. Univariate prediction equations were EHGE = 11.8566Ash-0.0421 (P <0.05), EHGE = 0.1535GE1.5642 (P <0.05), and EHGE = 0.1020TS1.1561 (P <0.05). The total starch, AP/AM, and ash of the chemical compositions were highly related to TME. The corresponding univariate regression equations were TME = 21.9355TS-0.0910 (P <0.05), TME = 15.6590AP/AM-0.0559 (P <0.05), and TME = 15.0778Ash0.0442 (P <0.05). The mean EHGE was equivalent to 78.5% of TME, but their correlation coefficient was low. In conclusion, chemical composition was predictive of EHGE and TME of corn samples for ducks, but the correlation of EHGE and TME was low

Estereótipos de gênero e leitura multimodal crítica na formação continuada de professores de línguas
Authors: Grando Roziane Keila
Published: January 2021

Com a dinâmica de textos multimodais e a sua presença nas práticas sociais, o ensino de leitura vem demandando investimento na formação crítica do leitor e dos formadores de leitores. Essa formação é possível por intermédio da Pedagogia dos Multiletramentos no ensino de línguas. Assim, optar por um ensino de línguas que esteja ancorado nos multiletramentos abre espaço para a inclusão das questões identitárias e para a divulgação dos direitos humanos na Escola. A partir desse recorte, o objetivo do trabalho é analisar um evento de formação de professores que versou sobre o anúncio audiovisual da cerveja Skol, intitulado “Reposter - Redondo é sair do seu passado”, veiculado no ano de 2017. A problematização da discussão recai sobre como a linguagem tem sido usada na condição de suporte para as diferenças de gênero. Inscrita no campo da Linguística Aplicada, a pesquisa caracteriza-se como um estudo de caso, com uma abordagem interpretativista. Os dados obtidos nesse estudo de caso ajudam na compreensão de que é necessário investir na agenda de formação que auxilie no entendimento de que tratar de diversidade cultural também envolve tratar das identidades de gênero.
Por que usar a LM na aula de LE

Published: January 2021

Uma questão recorrente com a qual se deparam os professores de língua estrangeira (LE) é oque fazer quando os alunos se expressam em sua língua materna (LM) durante a aula. Esteartigo apresenta argumentos em favor do uso LM como recurso para a aprendizagem de LE.Ainda que a não exclusão da LM na sala de aula de LE não seja uma proposta inovadora, acomunicação integralmente em LE desde a primeira aula ainda é considerada uma vantagemem muitos cursos de LE, em oposição àqueles que aumentam progressivamente o inputconforme a evolução do aluno. De fato, o input linguístico e as oportunidades de mobilizaçãooral e escrita da LE têm maior relevância para a aprendizagem do que explicações sobre aestrutura da língua; entretanto, é possível e desejável empregar a LM como recurso paraotimizar a aprendizagem de qualquer LE. Assim, apresento aqui alguns modelos de ensinoplurilíngue elaborados para a realidade europeia e os repensamos de acordo com a realidadebrasileira. Defende-se, desse modo, a perspectiva translíngue para o ensino de LE, superandoa ideia de plurilinguismo enquanto conhecimentos separados de línguas não relacionadasentre si.
O filme “Corra!” na perspectiva da Análise de Discurso Crítica
Authors: Gavioli-Prestes Cindy Mery , Rosa Marieli , Rosa Micheli
Published: January 2021

Este artigo tem como finalidade apresentar reflexões acerca das implicações do racismo na sociedade. Para isso, utiliza-se como corpus de análise o filme “Corra!” (2017), cuja temática é o racismo presente nos Estados Unidos. Utilizamos o método hipotético dedutivo, com a hipótese de que, na obra analisada, há o uso de palavras que fazem parte de um discurso racista que reflete a sociedade apresentada no longa-metragem. Dessa forma, o objetivo deste trabalho é, a partir dessas escolhas lexicais, analisar a categoria da Interdiscursividade (cf. Fairclough, 1992, 2003) presente nessa narrativa cinematográfica. Nossa pesquisa, então, é qualitativa e bibliográfica, sendo que nossa análise está baseada na Análise de Discurso Crítica, ADC, (FAIRCLOUGH, 2001, 2003), leva em consideração também Van Dijk et.al (2008, 2010), no que diz respeito ao racismo, e o conceito de ideologia proposto em Thompson (2011). O que pudemos verificar é que os resultados obtidos nesta pesquisa vão ao encontro de nossa hipótese inicial de que as escolhas das palavras utilizadas nos discursos estão relacionadas com a sociedade apresentada. Além disso, podemos afirmar que essa pesquisa contribui com a ADC e com a ideia de que as escolhas lexicais marcam também os diversos discursos, como os racistas, os preconceituosos e os discriminatórios, por exemplo.

TEACHERS’ PERCEPTIONS OF WORK ENVIRONMENT AND THEIR SENSE OF SELF-EFFICACY IN TEACHING EFL AT A UNIVERSITY IN VIETNAM
Authors: NGA PHAN THI TUYET
Published: January 2021

The paper looked at environmental factors that influenced the self-efficacy in teaching English as a Foreign Language (EFL) of a group of university teachers in Vietnam. Very little empirical research on teachers‘ self-efficacy in EFL contexts has been done and self-efficacy quantitative studies heavily outnumber qualitative studies. The present research took the form of a qualitative case study. Data collection tools included focus group discussions, individual interviews, journaling, and observations. Findings suggest that there were certain features of work context, e.g. the teaching support and teaching recognition, which may have affected what constituted sources of efficacy information and how they operated. The study proposes that institutional support with regard to providing clearer policies, giving teachers more freedom in the classroom and more opportunities to get involved in the decision-making process might help teachers overcome feelings of doubt about how competent they were in their teaching. Moreover, it would be helpful to improve teaching conditions at the university, including providing enough textbooks and reducing class size. The development of professional programs or courses at the home institution that meet the teachers‘ knowledge needs may enable them to overcome doubt about their teaching abilities and engender in them a positive sense of self-efficacy.

La renta mínima y el Defensor del Pueblo
Authors: Escobar Roca Guillermo
Published: January 2021

La renta mínima es un derecho subjetivo, reconocido de forma muy desigual por la normativa autonómica. El Derecho internacional la reconoce como derecho humano, pero de este reconocimiento no se han derivado consecuencias prácticas en el ordenamiento jurídico español. La renta mínima puede y debe ser un derecho fundamental, y mientras nuestros tribunales no lo reconozcan como tal, sería conveniente bien una ley básica del Estado bien una reforma constitucional, en coherencia con el Derecho internacional. La sociedad civil ha demostrado que se ha producido una vulneración estructural del derecho a la renta mínima y el Defensor del Pueblo ha recomendado recientemente pequeñas modificaciones normativas en esta materia. Sin embargo, sería conveniente una respuesta de esta institución mejor argumentada en términos de derechos humanos y fundamentales y más directamente dirigida a combatir la denunciada vulneración estructural.
El trabajo decente como Objetivo de Desarrollo Sostenible
Authors: Gil y Gil José Luis
Published: January 2021

El concepto-ético jurídico de trabajo decente, que promueve la OIT desde 1999 e institucionaliza la Declaración de la OIT de 2008 sobre la justicia social para una globalización equitativa, es uno de los objetivos de desarrollo sostenible. Dos ideas fundamentales resumen la respuesta de la OIT a la globalización y la crisis económica, y sirven de parámetro para examinar los progresos logrados en la consecución de ese objetivo de desarrollo sostenible y la coherencia de las últimas reformas laborales con los estándares que establece la Organización: proteger los derechos de los trabajadores y situar el empleo y la protección social en el eje de las políticas. En el marco de sus competencias, el Defensor del Pueblo puede contribuir a la promoción del trabajo decente, un objetivo de desarrollo sostenible cuya consecución es todavía lejana, incluso en los países más avanzados.
La erradicación de la pobreza: una cuestión de derechos civiles
Authors: García Manrique Ricardo
Published: January 2021

La pobreza constituye una violación de los derechos civiles. Una consecuencia jurídica práctica e inmediata de esta idea es que quienes sean titulares de los derechos civiles y estén en situación de pobreza han de disponer de una acción jurisdiccional para reclamar que esa situación suya sea remediada. Para sostener esa idea me apoyaré en cierta línea jurisprudencial contemporánea constituida por una serie de decisiones de tribunales nacionales e internacionales.Con carácter preliminar, haré una referencia a la Agenda 2030 y otra a la labor de los defensores del pueblo, con la intención de hacer ver: (1) que la idea que pretendo defender aquí puede contribuir a fortalecer la legitimidad y la eficacia de los objetivos de la Agenda; y (2) que se trata de una idea útil para la labor de las instituciones de defensa de los derechos humanos.

Subraya el papel esencial de los entes locales y regionales, en virtud de sus competencias en el ámbito social, para facilitar el acceso y el ejercicio efectivo de los derechos sociales por parte de los jóvenes; a tal efecto, se pone el énfasis en el cumplimiento de la Carta Social y su jurisprudencia como fuentes de inspiración para la acción local y regional en este terreno. El artículo hace un llamamiento a los entes territoriales para alentar a sus autoridades nacionales a firmar y ratificar la Carta Social Europea revisada y aceptar el procedimiento de reclamaciones colectivas. También les invita a difundir el texto de la Carta Social a través de sus propios canales de comunicación y redes sociales, así como a sensibilizar sobre los derechos sociales de los jóvenes a través de diversas iniciativas. Para los gobiernos de los Estados miembros, propone desarrollar y coordinar sus acciones de concienciación sobre los derechos sociales de los jóvenes con los otros niveles de gobernanza y los gobiernos de los Estados Partes en la Carta Social, involucrando a los gobiernos locales y regionales en todo el proceso de implementación de este instrumento jurídico.
