Вплив пінополістиролу на процес прогрівання стружково-полімерного пакета
Authors: Bekhta Pavlo , Baizova Liubov
Published: July 2019

Досліджено вплив пінополістиролу на процес прогрівання стружково-полімерного пакета в процесі пресування легких стружкових плит. Для фіксації температури, до якої прогрівається внутрішній шар стружково-полімерного пакета, використано мультиметр з приєднаною до нього термопарою, яку було розміщено всередині пакета. Пресування здійснювалося за питомого тиску пресування 2,4 МПа і температури плит преса 200 С. Пресували легкі стружкові плити (без пінополістиролу та з вмістом пінополістиролу 4, 7, 10%) розмірами 300×300×18 мм і щільністю 350, 450 і 550 кг/м3, личковані лущеним шпоном. Встановлено, що тривалість прогрівання стружково-полімерного пакета легких стружкових плит зменшується за збільшення в них вмісту пінополістиролу до 7%, після чого починає зростати. Додавання пінополістиролу до стружки спричиняє заповнення пустот з одночасним зростанням кількості контактів між стружкою, через яку передається тепло від периферії до центру стружково-полімерного пакета. Зростання вмісту пінополістиролу в стружково-полімерному пакеті більше 7% зумовлює сповільнення його прогрівання через те, що об’єм пінополістиролу є більшим, ніж стружки, а теплопровідність пінополістиролу є меншою порівняно з деревиною. Зі збільшенням щільності плит з 350 до 550 кг/м3 тривалість прогрівання стружково-полімерного пакета зменшується. Більша маса стружки в одиниці об’єму пакета зменшує його пористість, збільшує теплопровідність і, як наслідок, спричиняє швидше його прогрівання. Значення тривалості прогрівання середнього шару пакета легких стружкових плит до 100 oС із вмістом пінополістиролу 7% є меншим на 12-33%, ніж плит без пінополістиролу. Отримані результати дають змогу підвищити ефективність процесу пресування легких стружкових плит з вмістом пінополістиролу.

Gender Diversity and Educational Attainment in Non-Listed Private Firms: Evidence from Slovakia*
Authors: Ochotnický Pavol , Wilson Nick , Káčer Marek , Alexy Martin
Published: July 2019

The paper tests the impact of gender diversity and educational attainment of owners and company directors on the performance of private firms in the Slovak economy. The paper demonstrates that in retail trade the gender diversity both in owners and company directors within a company leads to higher total factor productivity and partially lower propensity to fail. However, in other industries the companies with higher proportion of females in the ownership structure or among company directors tend to be less efficient and grow less. Although there is evidence that higher proportion of females self-select into lower risk sectors and occupations, our main results hold after controlling for it. In terms of educational attainment, the companies with higher proportions of owners or company directors with university education are more productive and grow more in terms of turnover, but there is no evidence that default of companies is related to educational attainment. We suggest that education is unique and superior resource and it generally benefits the companies by having higher proportion of educated owners and/or directors.
Is Women's Job Satisfaction Higher than Men's? Self-Selection, Expectations or Utility Function
Authors: Sánchez-Sánchez Nuria , Fernández Puente Adolfo C.
Published: July 2019

This paper examines the paradox between high relative levels of job satisfaction and the characteristics of women's jobs compared to men's in Spain. Three hypothesis are considered: i) the existence of a selection bias when participating in the labour market; ii) of the presence of adaptive job satisfaction; and iii) the existence of differences related to preferences of different nature to strictly labour issues.

The study shows that, although having lower working conditions, women are more likely to be satisfied at work than men are. This paradox persists regardless of the inclusion of a great range of variables of different nature (objective and subjective), the age group and educational level under consideration. The Oaxaca-Blinder decomposition suggests that women's preferences are actually influencing the differences in job satisfaction. However, it is not demonstrated that these differences disappear as age decreases or educational level increases. The probable existence of a “glass ceiling” that prevents women from having access to posts of greater responsibility and higher wages could cause that women who actually reach them are more satisfied than their male colleagues. As the labour market and society become more equal, this paradox might dilute.
Adolescents’ compulsive sexual behavior: The role of parental competence, parents’ psychopathology, and quality of parent–child communication about sex
Authors: Efrati Yaniv , Gola Mateusz
Published: July 2019

Background and aims

Compulsive sexual behavior (CSB) has implications for clinical and non-clinical adult populations. Disposition to CSB has been shown to influence adolescence sexual behaviors, but the development of adolescents’ disposition toward CSB has yet to be examined in the family context. In this study, we investigated whether parent–adolescent communication mediates the links between parental characteristics and adolescents’ CSB.

Methods

The sample included 275 Israeli families [triad of mothers (age = 34–63 years,M = 45.48,SD = 5.46), fathers (age = 36–83 years,M = 48.33,SD = 6.63), and one adolescent (48.2% boys, 51.1% girls; age = 14–18 years,M = 16.23,SD = 1.18)]. Parents completed measures of psychopathology, parental self-esteem, and parental self-efficacy, and adolescents completed measures of quality of sex-related communication and CSB.

Results

The results indicate that, for girls, higher maternal self-esteem and lower psychopathology were linked with better sex-related communication and so with lower CSB. For boys, only parental religiosity was linked with the quality of sex-related communication and CSB, with religious parents having better communication than secular ones.

Discussion

The findings provide an opportunity for researchers to gain a better insight into the dynamics of familial factors in the development of CSB among adolescents.
Speech Acquisition in Monolingual Children Acquiring isiZulu in Rural KwaZulu-Natal, South Africa
Authors: Pascoe Michelle , Jeggo Zenia
Published: July 2019

In South Africa, isiZulu is the most widely spoken home language. However, research on children's speech acquisition in isiZulu is minimal and there are no published speech assessments that speech-language therapists can use to identify children with speech sound disorders acquiring this language. In our research we aimed to document speech sound acquisition of 32 isiZulu-speaking children aged two years, six months to six years, five months in rural KwaZulu- Natal, South Africa. An isiZulu speech assessment was developed and used to assess the children's speech in terms of phonetic acquisition, word shape and phonological processes. In the study, the implosive, plosives, nasals, affricates and vowels were mastered by the youngest children. The click /!?/, approximant /l/ and fricative /?/ may be among the last consonants to develop: they had not been mastered by the oldest group. Two-syllable structures were mastered early while structures of four/five syllables were still developing at 6;5. Participants in the older age groups could produce target words more accurately and used fewer phonological processes. The findings are discussed in relation to normative data from other Bantu languages. Knowledge of isiZulu speech sound development will assist clinicians working with isiZulu-speaking children in assessing and managing their speech difficulties: an important step towards ensuring that speech-language therapy services are relevant to all children in South Africa.
“I have three years old”
Authors: Nicoladis Elena
Published: July 2019

There is evidence that adults store fixed expressions as both units and compositionally in their mental lexicon. According to Usage-Based theories, children initially acquire memorized chunks of language (fixed expressions) and gradually abstract productive patterns (compositional representation). This study addresses whether a French-English bilingual child has compositional representation of fixed expressions using diary data on her use of fixed expressions requiring the verb to be in English and avoir ‘to have’ in French between the ages of 3;4 and 4;3. According to Usage-Based theories, children should learn these fixed expressions as fixed expressions and therefore show little cross-linguistic influence. However, from the earliest age under study, this child occasionally used the non-target verb, suggesting that her representation of these fixed expressions was already also compositional.
La relación entre valores y normas, según Hilary Putman a propósito de su discrepancia con Jürgen Habermas
Authors: Villalba Marisa Beatriz
Published: July 2019

En este trabajo, presentamos las líneas claves de la posición sostenida por Hilary Putman y los principales contrastes que el autor señala respecto de la visión de Jürgen Habermas, en el marco de un caluroso debate acerca de la relación entre los valores y las normas. Entre los temas abordados, destacan la posibilidad (o no) de separar valores y normas, cual sea el contenido universal de los enunciados éticos, en qué se funda la obligatoriedad de las normas y qué papel desempeña la discusión en la situación ideal de habla, base de la ética del discurso habermasiana. Según entendemos, el debate pone de manifiesto tanto las debilidades parciales de ambas posiciones, cuanto las fecundas y latentes posibilidades de complementariedad.

Does Gender Significantly Predict Academic, Athletic Career Motivation among NCAA Division I College Athletes
Authors: Tudor Margaret , Ridpath B. David
Published: July 2019

American society has had college athletics at its core for over a century (Rader, 2009) and is ubiquitous in University life.  College athletes’ performances both on and off the field have been scrutinized in both popular and academic literature.  Other examples include the documentation in student development literature that meaningful engagement outside traditional classroom settings can have positive effects on a student’s (athlete or not) personal development (Pascarella & Terenzini, 2005). College athletes’ individual experiences have received considerable attention in the popular media and literature as the pressures to perform both athletically and academically are vast (Benford, 2007; Meyer, 2005). Previous studies have explored the athletic environment in terms of the emergence of leadership, team dynamics, team cohesion, and the motivational climate (Adie, Duda, & Ntoumanis, 2008; Allen, & Howe, 1998; Balaguer, Duda, & Crespo, 1999; Medic, Mack, Wilson, & Starkes, 2007; Tsang, 2007).  Other studies have focused more on individual attributes such as motivation to perform and participate, perceived ability, perceived competence, personal satisfaction, enjoyment, and social status (Amorose, & Horn, 2001; Hollembeak, & Amorose, 2005; Reinboth, & Duda, 2004; Sheldon, & Eccles, 2005; Van-Yperen, & Duda, 1999). The purpose of this study is to examine the effects of gender (men’s vs. women’s sports) on motivation towards academics, athletics, and career choice. Data were gleaned from male and female athletes at one large Midwestern NCAA Division I University using the Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2) and the Student Athlete’s Motivation toward Sports and Academics Questionnaire (SAMSAQ). Data are discussed and analyzed using various statistical methods and using Harter’s (1978) theory of perceived competence and Nicholls (1984) perceived theory of motivational climate to answer the theorized research question and hypotheses.
Meta-Analysis of Randomized Clinical Trials Comparing Active Treatment with Placebo in Metastatic Neuroendocrine Tumors
Authors: Capdevila Jaume , Hernando Jorge , Perez-Hoyos Santiago , Roman-Gonzalez Alejandro , Grande Enrique
Published: July 2019

Background

Most guidelines still recommend active surveillance for patients with asymptomatic, unresectable neuroendocrine tumors (NETs). However, recent findings from several randomized placebo-controlled trials suggest that most patients would benefit from active treatment. We conducted a meta-analysis of pooled outcomes from clinical trials in which an active treatment arm was compared with placebo to determine whether active treatment provides a survival advantage.

Materials and Methods

This meta-analysis evaluated six trials that compared a medication with placebo in patients with an asymptomatic, metastatic NET. The trials were heterogenous with regard to the active medication (octreotide, lanreotide, sunitinib, everolimus, Lu-Dotatate) and tumor localizations (gastrointestinal, pancreas, lung). Overall survival (OS) and progression-free survival (PFS) for the placebo and active treatment arms were obtained from individual trial data and combined to obtain pooled outcomes.

Results

The individual trials all reported significantly better PFS outcomes for active treatment. The pooled data confirmed this advantage. At months 3, 6, 12, 18, and 24, pooled PFS rates for the placebo and treatment arms, respectively, were 92.9% versus 96.9%; 54.3% versus 83.7%; 35.5% versus 68.5%; 25.1% versus 54.7%; and 17.7% versus 61.0%. OS was also higher in the active treatment groups. At months 6, 12, 24, 36, 48, and 60, OS rates (placebo vs. active treatment), respectively, were 88.1% versus 93.4%; 84.1% versus 86.2%; 67.4% versus 76%; 56.6% versus 64.4%; 49.9% versus 61.0%; and 41.7% versus 45.9%.

Conclusion

This meta-analysis confirms findings from recent clinical trials indicating that active treatment yields better survival outcomes than placebo. Importantly, these findings were obtained across a wide range of patient profiles and diverse medical treatments for metastatic NETs. Given the lack of reliable prognostic factors to determine a priori which patients are unlikely to benefit from active treatment, these findings support early treatment in most patients.

Implications for Practice

Although most guidelines still recommend active surveillance for patients diagnosed with metastatic neuroendocrine tumors, the results of this meta-analysis, together with recent data from key clinical trials, suggest that most patients could benefit from upfront active treatment. However, more data are needed to confirm this.

Estudo de caso com o objetivo de analisar o processo adaptativo de estudantes africanas imigrantes no Ceará, realizado na Universidade da Integração Internacional da Lusofonia Afro-Brasileira em Redenção-Ceará-Brasil. Participaram do estudo onze estudantes procedentes de Países Africanos de Língua Oficial Portuguesa (PALOP’S). De acordo com a nacionalidade, incluímos: três de Moçambique; duas de São Tomé e Príncipe; duas de Cabo verde; duas de Angola; e duas de Guiné-Bissau.  As estudantes estavam na faixa etária de 22 a 32 anos. Com relação à renda mensal, a individual variava de R$ 500,00 a R$ 1.020,00, e a familiar de R$ 500,00 a R$ 1.300,00. Dentre as estudantes, identificamos fatores de risco para Síndrome Hipertensiva da Gravidez, além da cor negra. Os motivos da migração estavam relacionados com a busca de uma formação acadêmica, conquista de melhores condições de trabalho e de realização profissional e disponibilizar melhorias para os familiares e conhecidos do País de origem mediante o seu regresso. Para sete estudantes houve facilidades, e estas se relacionavam com oportunidade de estudo financiado, liberdade, segurança, melhores condições de vida, e amadurecimento. As dificuldades de adaptação no País eram inerentes ao tipo de alimentação, clima, cultura, racismo/preconceito, custo com moradia, acesso aos serviços de saúde, insegurança e violência. A partir da análise dos resultados consideramos que as estudantes imigrantes africanas enfrentavam dificuldades no processo adaptativo migratório mediadas pela diferença cultural, discriminação, racismo e poder aquisitivo aquém das ofertas locais relacionadas ao atendimento às suas necessidades básicas.
Inclusión digital y democratización del conocimiento. Los Proyectos Flor de Ceibo y Flor de Ceibo Conecta2 en diálogo con las políticas públicas
Authors: Morales-González María Julia
Published: July 2019

La inclusión digital fue vista a principios de la década del 2000 como un paso imprescindible para la inclusión social en un mundo altamente tecnologizado, que permea todos los ámbitos donde las personas interactúan. Para lograr la inclusión digital de sus ciudadanos, los distintos países implementaron distintas políticas, cuyas estrategias estarán signadas por la orientación política e ideológica (Lago et al, 2015) Uruguay no fue ajeno a este fenómeno y en el ámbito educativo surgió el Plan Ceibal. Esta política vista como revolucionaria dentro y fuera de fronteras, vehiculizó su implementación a través de la escuela pública, importante referente de identidad nacional (en Uruguay) que fuera construida bajo los valores de la educación, la cultura y la homogeneidad de su población. En este contexto la Universidad no podía quedar ajena y desarrolla los Proyectos Flor de Ceibo (2008-2017) y Flor de Ceibo Conecta2 (2017-actualidad), acompañando crítica y reflexivamente el Plan Ceibal, a través de la integralidad, donde se conjuga enseñanza, investigación y extensión, con una metodología de abordaje por problemas, buscando facilitar la apropiación tecnológica, el desarrollo de competencias y la democratización del conocimiento, en un escenario de 2da Reforma Universitaria.

Examining the breaking and bending behaviors of the polymethylmethacrylate composites reinforced with hazelnut shell powder
Authors: BÜYÜKKAYA Kenan
Published: July 2019

The objective of the present study is to reveal the toughening effect of the hazelnut shell on the brittle matrices by using the bending and breaking methods. The polymethylmethacrylate composites reinforced with hazelnut shell powder with 50µ particle size at the weight concentrations of 5%, 10%, 15%, and 20% were prepared. The polymer beam samples were exposed to heat cure procedure and the initial notches were created at a/W=0.1, 0.2, 0.3, 0.4, and 0.5. The Mode I breaking behaviors of the notched at single edge and non-notched composite samples were examined by using three-point bending test. The critical stress intensity factor (KIC), J-integral, initial notch depth, and compliance methods were used in calculations. Besides them, the bending module and bending stress values were calculated. The microstructures of HNSP/PMMA composites were determined by using XRD (x-ray diffractometer), FTIR (Fouirer Transform Infrared Spektrofotometre), and SEM (scanning electron microscope) analyses. According to the results obtained, it was determined that the bending strength, elasticity module, and fracture toughness values increased at 10% additive ratio for the HNSP (hasel nut shell flour)/PMMA (polymethylmethacrylate) composites.

Elementos importantes de la cadena de abastecimiento del sector automotriz en Colombia
Authors: Peña-Meneses Gilma Rocio , García-Cáceres Rafael Guillermo
Published: July 2019

Introducción: La globalización ha sido un aspecto principal para el desarrollo del paradigma de la Cadena de Abastecimiento (CA), la cual busca minimizar los costos de producción, y maximizar la oferta de bienes con ventajas competitivas, en términos de economías de escala y mano de obra. La industria automotriz es objeto de estudio permanente, debido al contexto competitivo de la industria en crecimiento en el tiempo, por diversos factores incluyendo: el impacto ambiental, la movilidad, la personalización, el incremento de competencia directa e indirecta, los cambios sociales y el manejo del riesgo.

Objetivo: El presente artículo busca destacar la importancia y caracterizar la CA del sector automotriz de un país en desarrollo como es el caso de Colombia.

Metodología: El estudio se realizó a través de una metodología compuesta de los siguientes pasos: Paso 0. Proporcionar el contexto económico y social a nivel global y doméstico de la CA; Paso 1. Identificar las etapas, escalones y enlaces de la CA; Paso 2. Describir el valor agregado de los agentes y componentes de la CA; Paso 3. Describir las especificidades del desempeño de la CA; y Paso 4. Diagnóstico y conclusiones sobre la condición de la CA.

Resultados: El sector automotriz y de motos constituyen el 4 % de la producción bruta industrial colombiana y la ciudad capital es el principal contribuyente a la generación de empleo a nivel nacional, además de concentrarse en tres grandes ejes: ensamble de vehículos, producción de autopartes y ensamble de motocicletas.

Conclusiones: Se evidencian dos cadenas importantes para el sector automoriz; la importación de vehículos terminados (ensamble fuera de Colombia) y automotores ensamblados dentro del país. Y para Colombia el principal reto de la distribución de las marcas de importados es el soporte de producto, servicio postventa y repuestos en toda la geografía nacional.
PAROTİS BEZİ KİTLELERİNİN BENİGN MALİGN AYRIMINDA ULTRASONOGRAFİ VE BİLGİSAYARLI TOMOGRAFİNİN ROLÜ
Authors: Damgacı Lale
Published: July 2019

Amaç: Parotis bezi kitlelerinde ultrasonografi (US) ve
bilgisayarlı tomografi (BT) bulgularının benign-malign ayrımındaki rolünü
araştırmak.

 

Materyal Metod: Fizik muayene ile parotis bezinde kitle saptanan
45 hastaya US ve BT incelemesi yapıldı. US’de kitlelerin yeri (yüzeyel
lob-derin lob), boyutu, konturu (iyi
sınırlı (düzgün-lobüle), irregüler), ekojenitesi (anekoik, hipoekoik, izoekoik veya
hiperekoik), eko yapısı (homojen veya heterojen) değerlendirildi. BT’de boyut,
kontur (iyi sınırlı (düzgün-lobüle), irregüler), kontrast tutulumu (homojen,
heterojen) değerlendirildi. Otuzdokuz olgu opere oldu ve histopatolojik tanı
aldı. Altı olguya ince iğne biyopsisi sonrası histopatolojik tanı kondu.

 

Bulgular: Kırk beş kitlenin 39’u (86,7%) benign, 6’sı (13,3) maligndi.
Benign olan 39 kitlenin 28’i pleomorfik adenom, 5’i Warthin tümörü, 1’i
kapiller hemanjiom, 1’i, dermoid kist, 1’i lipom, 2’si tüberküloz lenf adenit,
1’i granülomatöz lenf adenit tanısı aldı. Malign olan 6 olgunun 1’i adenoid kistik
kanser, 2’si lenfoma, 1’i malign melanom, 1’i kondrosarkom, 1’i mukoepidermoid
karsinom tanısı aldı. Benign lezyonların tümünde US’de ve BT’de düzgün veya
lobüle kontur saptanmış olup lezyonlar iyi sınırlıydı. Lenfoma saptanan 2
olguda iyi sınırlı ve lobüle konturluydu. Malign olan 4 lezyonda US ve BT’de
irregüler kontur izlendi. US’de pleomorfik adenomların %79’unda, Warthin
tümörlerinin %40’ında, lenfomalı 2 olguda homojen eko yapısı saptandı.
Pleomorfik adenomların %21’inde ve tüm malign kitlelerde heterojen eko
saptandı. BT’de pleomorfik adenomların %92,9’unda, Warthin tümörlü olguların
%40’ında, lenfomalı iki olguda homojen kontrastlanma saptanırken, Pleomorfik adenomların
%7,1’inde, malign olan 4 olguda heterojen kontrastlanma izlendi. Warthin
tümörlü 3 olguda kistik komponent izlendi.

 

Sonuç: US ve BT parotis kitlelerinde benign-malign ayrımında ve lezyonların
ayırıcı tanısında kullanılabilir. İrregüler kontur ve çevre dokulara invazyon maligniteyi
düşündürmelidir. BT ile lezyonların yerleşim ve uzanımları US’ye göre daha iyi
değerlendirilmektedir.
FEMUR KIRIK MODELLERİNDE İKİLİ VE ÜÇLÜ TİTANYUM ELASTİK ÇİVİ UYGULAMALARININ BİYOMEKANİK OLARAK KARŞILAŞTIRILMASI
Authors: Çulcu Ahmet
Published: July 2019

AMAÇ: Bu çalışmanın amacı, pediatrik femur cisim transvers ve parçalı kırık modellerinde iki adet retrograt titanyum elastik çivi (TEÇ) uygulaması ile iki adet retrograt bir adet anterograt TEÇ uygulamasının, sentetik kemik modeller üzerinde vertikal ve rotasyonel kuvvetlere karşı biyomekanik stabilitelerinin araştırılmasıdır.GEREÇ VE YÖNTEM: 24 adet sentetik femur modelinde oluşturulan transvers ve parçalı kırık paternleri ikili (retrograt) ve üçlü (iki adet retrograt bir adet anterograt) TEÇ ile fiske edildi. Oluşturulan fiksasyon modelleri rotasyonel ve vertikal kuvvetlere maruz bırakılarak stabiliteleri biyomekanik açıdan incelendi.BULGULAR: Transvers kırığın üçlü TEÇ ile fiske edildiği modellerde 10 derecelik açı değişimine neden olan rotasyonel kuvvet ortalama 4.92N iken, ikili TEÇ uygulanan modellerde ortalama 1.86N olarak bulunmuştur (p=0.002). Parçalı kırıkların fiske edildiği üçlü ve ikili TEÇ modellerinde 10 derecelik değişim için gerekli rotasyonel kuvvetler sırasıyla 3.43N ve 1.77N bulunmuştur (p=0.002). İkili TEÇ uygulanan transvers kırık oluşturulmuş modellerde kırık hattında 5mm deplasman oluşturan ortalama kuvvet 103.6N olarak bulunmuşken, üçlü TEÇ’te bu kuvvetler ortalama 135.7N’dur (p=0.238). Parçalı kırık modellerinde 10 derecelik açılanma oluşturan vertikal kuvvetler ikili ve üçlü TEÇ uygulanan modellerde sırasıyla 83.8N ve 86.1N olarak tespit edilmiştir (p=0.87).SONUÇ: Rotasyonel kuvvetler açısından transvers ve parçalı kırıklarda üçlü TEÇ modelinin daha stabil fiksasyon sağladığı bulunmuşken, vertikal kuvvetlere karşı meydana gelen açılanma ve deplasman miktarı açısından ikili ve üçlü TEÇ arasında anlamlı fark bulunamamıştır.

Problems of plasma-facing materials degradation and in-vessel element destructions, tritium accumulation and plasma pollution can be overcome by the use of liquid metals with low atomic number. The best candidate as a material for divertor receiving plates and other in-vessel devices is lithium. One of the problems associated with the use of such lithium systems in the fusion reactors is to determine the parameters of the working gases interaction with plasma facing surfaces under conditions simulating real operation, i.e. under conditions of neutron and gamma radiation. This paper describes a technique of the reactor experiments to study lithium capillary-porous systems (CPS) interaction with deuterium under neutron irradiation. The neutron-physical and thermophysical calculations were the basis for the design development and further manufacture of a unique irradiation ampoule device with a lithium CPS sample. Several experiments were performed to calibrate the deuterium fluxes through experimental cell with lithium CPS; and preliminary results of these experiments were obtained.
Digital cooperatives as channels for digital work in the context of the collaborative economy
Authors: Arrieta Idiakez Francisco Javier
Published: July 2019

At present different bodies, associations, platforms etc. vary greatly in their definitions of the collaborative economy. This is because there are many differences between models and platforms within the term ‘collaborative economy’. Taking this diversity into account, this study will focus on the platforms dedicated to the provision of services. The first major issue will be the need to delimit and establish links between a multitude of concepts that emerge within the so-called collaborative economy, such as the Gig economy and the On-demand economy. The ultimate purpose is to limit the concept of collaborative economy for the purposes of the research carried out here. It was not for nothing that the European Commission recommended that legislators and courts should review professional regimes in the context of the new economy, while expressing its clear support for collaborative economy platforms in its report ‘A European agenda for the collaborative economy’ (2016). There is therefore a need to address the modality of platform-based work (also called digital work), with the aim of ensuring that standards are upheld regarding the working conditions and social protection of people who provide their services under this modality. This study, then, analyses the challenges, and positive and negative aspects of this new situation. The main conclusion is that cooperatives are the best means to channel the collaborative economy, under the modalities of platform-based or digital work. This will require studying and analysing the new models of cooperatives, and advocating digital cooperatives, outside the so-called cooperatives of self-employed workers, the true cooperative character of which is often doubtful. The conceptual delimitation of digital cooperatives and their differentiation from ‘classic’ cooperatives will also be discussed, which will involve providing some insights into the characteristic features of digital cooperatives. This research uses the descriptive, comparative and propositional legal methods. The descriptive method is used to define the concept of collaborative economy and the sub-concepts that it includes in terms of the provision of services; and to identify new forms of platform-based or digital work, and delimit the field of action of digital cooperatives, as the most appropriate means to channel these new forms of work. The comparative method will be useful to analyse the various existing professional regimes that can accommodate the new forms of work available within the collaborative economy. Finally, the propositional method will argue that digital cooperatives are the best solution to shape work within the collaborative economy.Received: 27 November 2018Accepted: 07 March 2019Published online: 22 July 2019
Cuidados parentais hipossuficientes versus negligência parental: discussões e proposições teóricas
Authors: Fonseca Hivana Raelcia Rosa , Ferreira Maria D'Alva Macedo
Published: July 2019

A negligência parental é a situação na qual a família, dispondo de recursos, não os utiliza adequadamente no cuidado com as crianças e adolescentes sob sua responsabilidade. Ainda existem muitas discussões acerca da operacionalização desse conceito, sendo comum a confusão entre negligência e pobreza. O objetivo desse trabalho é discutir a qualidade do cuidado e os efeitos no desenvolvimento em contextos de negligência parental e em situações nas quais há indisponibilidade de recursos de cuidado. Trata-se de um ensaio teórico reflexivo que visa contribuir com a caracterização e distinção da negligência parental e situações nas quais não há disponibilidade de recursos para cuidados, aqui chamado de cuidados hipossuficientes.  A compreensão e o enfrentamento dessas situações deve ser diferenciada, tendo em vista que a produção subjetiva e psicossocial nos dois contextos são atravessas por fenômenos diferentes.

Published: July 2019

Este é um estudo avaliativo, quantitativo-descritivo, que teve como objetivo avaliar os efeitos de um programa de exercícios multissensoriais na mobilidade de tronco e no equilíbrio de idosos comunitários frequentadores de um grupo de exercício físico orientado, realizado no segundo semestre de 2018. Participaram do estudo 20 idosos que foram submetidos a uma avaliação inicial do Índice Massa Corpórea e Teste do Alcance Funcional e após oito semanas de intervenção ao Teste do Alcance Funcional. Foram realizados exercícios multissensoriais, duas vezes por semana, com duração de 60 minutos por oito semanas. Os resultados mostraram que os idosos apresentam IMC de 26,33 ± 4,48, considerado dentro do limite de normalidade para idosos e no Teste do Alcance Funcional a média inicial foi de 31,98 ± 6,13 e após intervenção, 34,45 ± 8,77 (p=0,08), indicando que embora tenha havido melhora em valores absolutos, o treinamento não foi suficiente para promover melhora significativa.
Acompanhamento e ações de apoio oferecidas aos professores iniciantes no contexto escolar
Authors: Glasenapp Dirlene , Hobold Marcia Souza
Published: July 2019

Este estudo visou analisar de que modo os professores iniciantes são acompanhados no cotidiano de sua prática pedagógica e quais ações de apoio lhes são oferecidas no contexto escolar por parte dos diretores e supervisores escolares. Trata-se de uma pesquisa que teve como objetivo conhecer o processo de acompanhamento e as ações de apoio oferecidas aos professores iniciantes na Rede Municipal de Ensino de um município catarinense. Caracteriza-se como uma investigação de cunho qualitativo, em que se utilizou a entrevista semiestruturada como instrumento para a coleta de dados e a análise de conteúdo para sua interpretação. Os participantes são diretores, supervisores escolares e professores experientes, ou seja, profissionais que recebem os docentes iniciantes nas escolas de Ensino Fundamental. Os principais autores que sustentam os aportes teóricos são: García (1999, 2009), Giovanni e Guarnieri (2014), Imbernón (2011), Libâneo (2008), Nono (2011) e Placco, Souza e Almeida (2012). Os resultados apontam que são oferecidas aos professores iniciantes ações pontuais, de acordo com as demandas vivenciadas no contexto escolar. Os dados revelam, ainda, que o acompanhamento desses professores é realizado preponderantemente pelos supervisores escolares, sendo que a direção se envolve mais nos aspectos administrativos concernentes a esse profissional. Porém, a sobrecarga de trabalho dos supervisores escolares não tem favorecido a realização de um acompanhamento sistemático desses docentes, o que pode fragilizar o processo de desenvolvimento profissional do professor iniciante.
The Marañón-Huallaga exchange route
Authors: Rojas Berscia Luis Miguel , Eloranta Rita
Published: July 2019

In this article we claim that stone classifier-based numeral systems in a number of unrelated North-western South American language families/languages such as Kawapanan, Cholón-Hibito, Munichi, and, tentatively, Quingnam emerged due to calquing or loan translation (Weinreich 1963; Epps 2006, 2013). In addition, although the donor language remains unknown, we argue for this to be a case of a poorly attested grammaticalisation path of numeral classifiers and numerals, namely STONE>CLASSIFIER, as presented in Conklin (1981), for languages such as Gorontalo, Kam-Muang, White Tai and Western Austronesian languages (Conklin 1981, 233, 234; mentioned by Aikhenvald 2000, 446). Moreover, ethnohistorical and historical evidence (Reeve 1994, 125) suggests that pre-Hispanic societies in the Marañón-Huallaga area shared a salt-stone-based trading system, henceforth SBT. This is remarkable, since other adjacent language families, such as Quechua and Chicham, do not show such a pattern for the formation of their own numerals. We claim, tentatively, that these common trade networks may be the sociohistorical motivation for the diffusion of this calquing pattern in the area.
Estratégias da posse em wayana e seu mosaico morfo(fono)lógico
Authors: Camargo Eliane , Wajana Asiwae
Published: July 2019

As línguas caribes apresentam uma morfofonologia e morfossintaxe complexas. O wayana reflete bem essas características linguísticas, como veremos no estudo descritivo proposto, sobre a tipologia da construção de posse, que segue critérios morfofonológicos e morfossintáticos. Duas ordens dos elementos caracterizam uma determinação nominal, especificadas por uma morfologia remetendo à relação alienável e inalienável entre o elemento possuidor e o elemento possuído. Nas construções de posse, destaca-se a formação de sintagmas e predicados nominais, caracterizados por predicação averbal e por presença da cópula nas 1a e 2a pessoas e da partícula existencial na 3a pessoa. Os afixos de codificação do possessivo são vários e algumas das estruturas do possessivo expressam valores aspecto-temporais como -hpe e -hme e seus correspondentes operadores de privação de posse, -pïn e -mïn. As construções com o associativo revelam a posse comitativa, o que é bastante inusual na literatura linguísticia. O presente estudo focaliza a expressão de posse na gramática do wayana e as suas diferentes estratégias morfofonológicas, morfológicas e semânticas.
