Published: July 2020

ABSTRACT
Sol-gel–synthesized nano zinc oxide (ZnO) is introduced as a cure activator in carbon black (CB)– and silica-filled natural rubber (NR) composites. The performance of sol-gel–synthesized nano ZnO was systematically compared with conventional ZnO for various filled NR composites in terms of cure, mechanical, aging, and thermal properties. At a filler loading level of 40 parts per hundred parts of rubber (phr), only 1 phr nano ZnO provided a better cure rate index and tensile strength as compared with 5 phr conventional ZnO in CB-filled NR composites. On the other hand, at a 40 phr filler loading level, the cure and mechanical properties of the 1 phr nano ZnO cured NR/silica composite were comparable with the properties of the 5 phr conventional ZnO cured NR/silica composite. At the same filler loading level, both 1 phr nano ZnO and 5 phr conventional ZnO had a similar effect on the thermal stability of NR/CB and NR/silica composites. As a whole, 1 phr sol-gel–based nano ZnO could be used as an efficient cure activator instead of 5 phr conventional ZnO in CB- and silica-filled NR composites with successive reduction of ZnO level.

Facts on the tourism issues that emerged in Karangasem Regency showed a lack of synergy between spatial planning and tourism destination planning. In addition, tourism development in Karangasem Regency is vulnerable to exploitation of natural and cultural resources. Therefore, in developing tourism in Karangasem Regency, careful measures are needed to avoid the degradation of local cultural values. This study aimed to formulate and develop a policy framework for tourism destination development in the regional spatial system of Karangasem Regency, Bali, Indonesia. This study used a qualitative research approach with multicriteria-based policy (MULTIPOL) analysis. The data were collected through document studies, interviews, and focus group discussions (FGD). MULTIPOL analysis integrates a participatory approach into multi-criteria principles, and therefore, the MULTIPOL framework is based on the information obtained from stakeholders through FGD. In this study, the interviewees were chosen through purposive sampling by involving 15 experts consisting of 3 community leaders, 7 local government officials, and 5 managers of tourist attractions. The results showed that the tourism village development action scored the highest for the conservation-based tourism policy, regional potential-based tourism policy, infrastructure development and accessibility policy, and community-based tourism management policy. Meanwhile, the highest-scoring policies in relation to the established integrated development scenarios, are the regional potential-based tourism policy, the community-based tourism management policy, and the conservation-based tourism policy.
Determinants of opportunity entrepreneurship: a comparison between males and females in Mexico
Authors: Elizundia María Eugenia 
Published: July 2020

The majority of research on opportunity entrepreneurship, defined as startups attempts based on perceived business opportunities, has been conducted in either high- or low-income countries. However, the characteristics of these types of entrepreneurship in middle-income countries are very scarce, especially in Latin America.
The purpose of this paper was to analyze and compare the factors that influence opportunity entrepreneurship using the data obtained from the Global Entrepreneurship Monitor (GEM) (Adult Population Survey [APS], 2015), comparing the results between males and females in Mexico.
The empirical research employs a logistic regression model. The main findings highlight that perceived capabilities, work status, income level, and age exert a positive influence on opportunity entrepreneurship, while the factors of fear of failure or education present exerting no influence on this type of venture. Also, the results show that there are no differences between males and females. The research contributes to an increasing literature of this phenomenon in one of the most important countries in this region.
La ocupación como elemento terapéutico de la práctica de Terapia Ocupacional en personas con disfunción física.
Authors: Navarrete Salas Erna , Hernández Lanas Oscar 
Published: July 2020

El presente ensayo aborda el uso terapéutico que los/las terapeutas ocupacionales entregan a la ocupación, desde el ámbito de la rehabilitación
en salud física.
El concepto de la ocupación se fundamenta desde una visión histórica y se contrasta con la conceptualización que puedan ser aplicadas al
quehacer de terapeutas ocupacionales que trabajan en este ámbito.
A lo largo del escrito, se aborda el impacto que tiene la disfunción física en la ejecución de ocupaciones significativa en personas que padecen
de esta condición. Se argumenta a favor de mantener la ocupación como núcleo de la intervención terapéutica y la utilidad que presenta como
recurso de intervención profesional. Los conceptos de ocupación como medio y ocupación como fin se proponen como una solución práctica
para desarrollar intervenciones en este ámbito.
Se concluye que es necesario que los/as terapeutas ocupacionales sean conscientes de la relevancia que tiene el uso de la ocupación al interior
de las dinámicas de intervención en salud física; consideren su integración en la practica profesional y expliciten su uso en los procesos de
atención directa de personas con disfunción física.
Triplectides Kolenati (Trichoptera: Leptoceridae) from Brazil: A new species, new records and an identification key
Authors: DESIDÉRIO Gleison Robson , PES Ana Maria , BARCELOS-SILVA Patrik , HAMADA Neusa 
Published: July 2020

The long-horned caddisfly genus Triplectides Kolenati, 1859 is the most species-rich within Triplectidinae, comprising about 90 species. Eight species have been recorded so far in Brazil, mainly distributed in the Southeast Region, and only one species has been recorded from the North Region. In this paper a new species of Triplectides is described and illustrated, Triplectides nessimiani Desidério & Pes sp. nov., based on adult males from Serra do Aracá, Amazonas, Brazil. We also provide the first record for Brazil of T. neblinus Holzenthal, 1988 and T. nevadus Holzenthal, 1988. In addition, an updated identification key to Triplectides species with occurrence in Brazil is presented.
Infancia y contenidos audiovisuales online en España: Una aproximación al consumo y a la mediación parental en las plataformas OTT
Authors: Marcos Ramos María , Pérez Alaejos María de la Peña Mónica , Cerezo Prieto Marta , Hernández Prieto Marina 
Published: July 2020

La convergencia multimedia y la llegada de Internet al mercado audiovisual ha afectado a las pautas de consumo y recepción de contenidos en el entorno familiar y en los procesos de alfabetización mediática de los menores. A pesar de que las cifras de consumo de televisión lineal por parte de los más pequeños se mantienen, es innegable la penetración progresiva en los hogares españoles de las plataformas audiovisuales, siendo fundamental el papel que realizan los padres/tutores.
El objetivo de esta investigación es identificar las prácticas de uso en dichas plataformas por parte de niños/as de infantil y primaria en España, y analizar los sistemas de mediación parental en el nuevo escenario de convergencia mediática, a partir de un estudio descriptivo realizado con 431 padres/madres o tutores. Para llevarlo a cabo se ha utilizado la herramienta metodológica Qualtrics, mediante la aplicación de un cuestionario a través de un muestreo en bola de nieve.
Tras el análisis de los resultados se constatan cambios importantes en la mediación parental, acordes con el incremento progresivo en la edad de los niños/as, aunque la regulación más frecuente en ambas franjas de edad está vinculada al tiempo que los progenitores o tutores permiten a los menores pasar frente a los diferentes dispositivos, más que en las restricciones en torno a los contenidos. Además, no se constatan diferencias significativas respecto al tipo de productos audiovisuales que consumen en la televisión lineal y en las plataformas OTT, predominando las series y las películas infantiles en edades más tempranas.
Evaluando la evaluación. Validación mediante PLS-SEM de la escala ATAE para el análisis de las tareas de evaluación

Published: July 2020

Una de las funciones esenciales del profesorado universitario se concreta en el proceso de toma de decisiones sobre los diferentes componentes que constituyen el diseño de los procesos de evaluación, siendo uno de sus elementos clave la calidad de las tareas de evaluación. En este estudio se presenta tanto la validación de un instrumento para la valoración por el estudiantado de las tareas de evaluación como el modelo que sustenta las relaciones entre los constructos que caracterizan las tareas de evaluación. A partir de una revisión de la literatura se ha elaborado un modelo teórico de las características de las tareas de evaluación y las relaciones existentes entre ellas. Para su comprobación se ha diseñado, sobre la base de un modelo de medida de carácter formativo, el cuestionario Análisis de las Tareas de Evaluación y Aprendizaje (ATAE). Mediante un diseño de cohorte se han obtenido un total de 1.166 cuestionarios cumplimentados por estudiantes de los grados de Administración y Dirección de Empresas (ADE) y Finanzas y Contabilidad (FYCO). La evaluación del modelo de medida y del modelo estructural se ha realizado mediante la técnica Partial Least Squares Structural Equation Modeling (PLS-SEM) utilizando el software SmartPLS_3. Los resultados muestran la no existencia de problemas de colinealidad y unos niveles elevados de importancia absoluta y relativa de cada uno de los ítems del cuestionario. Es de destacar, desde la percepción de los estudiantes, que el carácter retador de una tarea de evaluación se relaciona con la transferencia del aprendizaje, y cómo el uso de estrategias de comunicación y la demostración de una comprensión profunda son elementos mediadores de esta relación.

Effect of radiation on serum glycoproteins and glycosidases in patients with cervical carcinoma
Authors: Bhuvarahamurthy V. , Balasubramanian N. , Vijayakumar S. , Govindasamy S. 
Published: July 2002

AbstractObjective: The serum glycan moieties of glycoproteins and the activities of glycosidases were analyzed in order to elucidate the metabolism of glycoprotein in uterine cervical cancer. Methods: Serum was collected from patients at different stages of cervical cancer before and after treatment. The results were analyzed using Student's t‐test. Results: The glycan moieties such as sialic acid and fucose were significantly elevated even in the early stages of carcinoma, whereas a significant elevation in hexose and hexosamine levels was observed only in the advanced stages. Among the investigated lysosomal glycohydrolases, β‐d‐galactosidase, N‐acetyl‐β‐d‐glucosaminidase and α‐l‐fucosidase activities were elevated significantly at all stages except for stage I. The altered levels of glycoproteins and glycosidases were reduced to near‐normal levels after radiotherapy. Conclusion: The levels of glycan moieties and the activities of glycosidases can be used as diagnostic markers to asses the stage of cancer and can be used as prognostic markers during therapy.
Adolescent health: a Middle East and North African perspective
Authors: Özcebe H. , Akin A. 
Published: July 2002

AbstractAdolescence is a period of physical, psychological and social transition from childhood to adulthood. At present there are 95 million young people aged between 10 and 24 years in the Middle East and North Africa. Female education is increasing in these regions, but secondary school enrollment rates for girls lag behind those of their male counterparts. Average age at first marriage varies between 17.9 and 24.3 years, but teenage marriage is quite common. Total fertility rates are higher than the world average. Pregnancy at an early age often translates into a high fertility rate and high risks for women and their children. Female children's share of food, health care, work options and general care is often less than that of boys, because they are perceived to be less valuable than boys in some countries.
In vitro induction of radial‐like cells by leptomeningeal and cortical astroglial conditioned media. Effect of protease inhibitors
Authors: Colombo Jorge A. , Napp Mónica I. 
Published: July 2002

AbstractA population of subcultured astroglia from rat fetal cortex was transformed into radial‐like cells after exposure to cerebral cortex astroglial conditioned medium in vitro. Such changes were also induced by basal medium modified by fetal leptomeningeal subcultures, but not by postnatal leptomeninges nor by fetal skin fibroblasts. The radializing effects of astroglial conditioned medium were inhibited by previous heat treatment. The addition of protease inhibitors to the basal medium did not cause spontaneous radialization of subcultured cortical astroglia, but increased the length of cell processes and incidence of radial‐like forms when added to cortical astroglial conditioned medium. It is concluded that cortical astroglia and leptomeningeal cells share the capability of synthesizing and releasing diffusible molecules into the culture medium which act as morphogenetic inducers in vitro. Based on the present results, it is suggested that such effects would depend on the presence of instructive factor(s) in the conditioned medium which are able to induce rearrangement of the cytoskeleton, rather than on secreted molecules able to modify cell adhesion to the substrate.
The technocratic, humanistic, and holistic paradigms of childbirth
Authors: Davis‐Floyd R 
Published: July 2002

AbstractThis article describes three paradigms of health care that heavily influence contemporary childbirth, most particularly in the west, but increasingly around the world: the technocratic, humanistic, and holistic models of medicine. These models differ fundamentally in their definitions of the body and its relationship to the mind, and thus in the health care approaches they charter. The technocratic model stresses mind–body separation and sees the body as a machine; the humanistic model emphasizes mind–body connection and defines the body as an organism; the holistic model insists on the oneness of body, mind, and spirit and defines the body as an energy field in constant interaction with other energy fields. Based on many years of research into contemporary childbirth, most especially through interviews with physicians, midwives, nurses, and mothers, this article seeks to describe the 12 tenets of each paradigm as they apply to contemporary obstetrical and health care, and to point out their futuristic implications. I suggest that practitioners who combine elements of all three paradigms have a unique opportunity to create the most effective obstetrical system ever known.
Challenges and opportunities for donors in reducing maternal death and morbidity: lessons from the PMM experience
Authors: Richardson Y.C 
Published: July 2002

AbstractThe experience of the PMM Network offers several insights for donors seeking to work on maternal mortality, particularly in Africa where the risk of maternal death is highest. First, the projects provide evidence that multidisciplinary operations research can result in the development and implementation of successful, relatively low‐cost interventions. In addition, the work of PMM highlights the need for greater donor funding to build and support partnerships — to include researchers, communities and policymakers — that enhance sustainability of efforts. Finally, the work of the teams confirms the benefits of donor commitment to building local capacity. © 1997 International Federation of Gynecology and Obstetrics

Psychological autopsy studies – a review
Authors: Isometsä E.T. 
Published: July 2002

SummaryPsychological autopsy is one of the most valuable tools of research on completed suicide. The method involves collecting all available information on the deceased via structured interviews of family members, relatives or friends as well as attending health care personnel. In addition, information is collected from available health care and psychiatric records, other documents, and forensic examination. Thus a psychological autopsy synthesizes the information from multiple informants and records. The early generation of psychological autopsies established that more than 90% of completed suicides have suffered from usually co-morbid mental disorders, most of them mood disorders and/or substance use disorders. Furthermore, they revealed the remarkable undertreatment of these mental disorders, often despite contact with psychiatric or other health care services. More recent psychological autopsy studies have mostly used case-control designs, thus having been better able to estimate the role of various risk factors for suicide. The future psychological autopsy studies may be more focused on interactions between risk factors or risk factor domains, focused on some specific suicide populations of major interest for suicide prevention, or combined psychological autopsy methodology with biological measurements.
Measuring disability in subjects with anxiety disorders
Authors: Placchi M 
Published: July 2002

Summary
Subjects with anxiety disorders display substantial disabilities in
health-related quality of life. The Sheehan Disability Scale (SDS) and SF-36
Questionnaire (SF-36) have been administered to subjects with anxiety
disorders participating in psychopharmacology clinical trials and
observational studies to evaluate their impaired functioning. The SDS does
not address and does not include all the disabilities important to subjects
with anxiety disorders and susceptible to being affected by drugs with
anxiolytic effects, all of which are associated with significant problems.
As a single-state-in-time rating, the SDS is often inadequate to discern
subtle, but important,changes which may occur between measurements. The
SF-36 as a measure of health status can, on the other hand, assess only the
patient's behavior most directly affected by the disorder and treatment. As
a result, the SF-36 enables the differentiation of functioning and
well-being of subjects with anxiety disorders from diverse populations.
There is little documentary evidence that demonstrates the value and actual
performance of the SDS and SF-36 for the intended purpose. In the absence of
a general consensus concerning operational definition, the measurement of
disability in this patient population with these scales may be obsolete.
There is the need for more specific and simple instruments capable to assess
the distinct pattern of impairment associated with subjects with anxiety
disorders.
Delamination‐Free Functional Graphene Surface by Multiscale, Conformal Wrinkling

Published: July 2020

AbstractObtaining a delamination‐free wrinkled functional graphene surface in layered systems is an interesting challenge because the interface is usually too weak to withstand interfacial stress mismatch, which can trigger mechanical instability. In this paper, a general strategy is proposed toward addressing the delamination limitation imposed by fabricating conformal graphene wrinkles with bilayer systems of poly(methyl methacrylate) (PMMA) and polydimethylsiloxane (PDMS). To improve the interfacial strength, a postcuring transfer process is introduced to form a gradient interface layer without interfacial liquid between the PMMA and PDMS by entanglement of polymer chains during high‐temperature curing. Compared to the conventional wet transfer of graphene,the transfer method can greatly enhance the interfacial strength. The chemical and mechanical mechanisms underlying the enhancement are revealed both experimentally and theoretically in terms of the transition from the buckled‐induced delamination state to the delamination‐free wrinkled state. Moreover, the light diffraction behaviors of multiscale graphene wrinkles are initially demonstrated to be an interesting continuous pattern induced by overlapping. The delamination‐free conformal wrinkled functional graphene surface can provide valuable insight and design guidelines for the fundamental problems of deformed graphene and its applications in flexible functional devices.

AbstractA photoresist system for 3D two‐photon microprinting is presented, which enables the printing of inherently nanoporous structures with mean pore sizes around 50 nm by means of self‐organization on the nanoscale. A phase separation between polymerizable and chemically inert photoresist components leads to the formation of 3D co‐continuous structures. Subsequent washing‐out of the unpolymerized phase reveals the porous polymer structures. To characterize the volume properties of the printed structures, scanning electron microscopy images are recorded from ultramicrotome sections. In addition, the light‐scattering properties of the 3D‐printed material are analyzed. By adjusting the printing parameters, the porosity can be controlled during 3D printing. As an application example, a functioning miniaturized Ulbricht light‐collection sphere is 3D printed and tested.
