Nuevos mecanismos de colaboración público-privada para el desarrollo y acceso a la vacuna COVID-19: una perspectiva desde la teoría fundamentada
Authors: Jasso Villazul Javier , Torres Vargas Arturo
Published: February 2021

El objetivo de este texto es identificar y caracterizar cómo ante un hecho global de alto impacto, como puede ser una pandemia, se crean nuevas formas de colaboración y competencia entre los agentes (empresas, centros públicos de investigación y universidades, gobiernos), para acelerar el desarrollo de la vacuna para mitigar la pandemia de la enfermedad por coronavirus 2019 (COVID-19). El texto analiza el proceso de producción de vacunas para enfrentar al coronavirus SARS-CoV-2 a partir de las candidatas que se encuentran en la etapa de estudios clínicos de las fases más avanzadas, considerando las características de los agentes, los países a los que pertenecen, el perfil del financiamiento y los rasgos de la regulación. La aportación del trabajo es la de señalar que en el desarrollo de la vacuna de la COVID-19 se han impulsado nuevos patrones de colaboración público-privado a nivel nacional e internacional en múltiples ámbitos como son el científico-tecnológico, el financiero y el regulatorio. Estos patrones enmarcan una nueva lógica de colaboración que pudiera ser una experiencia para resolver problemas globales como son las pandemias, con una mayor flexibilidad y velocidad.
A study of the influence of high frequency cyclic loading on the structure and properties of weld connections in process pipelines
Authors: Gridasova Ekaterina A. , Sereda Maria A. , Zakirov ugli Shokhrukh S.
Published: February 2021

Introduction. Pipeline systems are exposed to several conditions that lead to a drastic reduction in their durability, primarily due to variable low-frequency and high-frequency loads arising in a process pipeline due to the operation of compressor units. Hence, fatigue failure occurs, leading to the pipeline failure. As early as at the pipeline installation stage, sections of process pipelines have weld connections, and thermal welding cycles have an adverse effect on the properties of materials exposed to fatigue loading. The study of weld connections in steel pipelines exposed to high-frequency vibrations and effects of weld seam defects on durability characteristics are the focus of this research.

Materials and methods. Low-carbon pipeline steel St20 was selected for the study. The radiographic inspection method, optical metallography, microhardness of structural phases, and the method of high-frequency fatigue tests were used.

Results. The results and principal conclusions about the effect of welding defects on durability characteristics of welded samples, made of pipeline steel and exposed to high-frequency fatigue tests, are presented; structural changes in weld connections are analyzed using optical metallography and microhardness methods. Defects of weld seams and their dimensions were identified by means of radiographic inspection. A comparative analysis of durability limits, demonstrated by the parent metal of the model material that has defective weld connections, and the same limits of defect-free samples is provided. The main causes of failure of weld joints, exposed to high-frequency vibrations, are identified.

Conclusions. Having summarized the research findings, we can argue that high-frequency vibrations have a negative impact on the parent metal of a process pipeline and its weld joints. The weld seam is the point of failure; defects trigger destruction, and their presence has a higher impact on fatigue characteristics than their dimensions or types. Characteristics of durability in case of exposure to high frequency loading applied to a weld joint in the gigacycle range are 67 percent below those of the parent metal.

Authors: Arias-Vanegas Eduar José , Duque-Nivia Guillermo , Acosta-Murgas Luis Angel
Published: February 2021

El mercurio es una sustancia contaminante que al estar presente en el ambiente, puede representar peligro para la salud pública, las personas están principalmente expuestas a este metal al consumir peces contaminados con mercurio. En este trabajo se determinó la concentración de mercurio espacio-temporal en el Pseudoplatystoma magdaleniatum de la ciénaga Zapatosa. Se realizaron cuatro muestreos en un periodo de un año entre julio de 2017 a junio de 2018, en cuatros estaciones con características diferentes. En el análisis de mercurio total se usó el método de medición directa según EPA 7473. Se capturaron un total de 185 individuos, todos presentaron concentración de mercurio, en todas las épocas y estaciones estudiadas y hubo diferencias significativas (p<0.005) en la interacción estación-periodo, las estaciones alejadas de los ríos presentaron los más altos valores y en la mayoría de los periodos no presentaron diferencias significativas (p<0.005); las estaciones cercanas a los ríos presentaron las menores concentraciones y tendieron a ser diferentes. La concentración promedio fue de 0.278±0.14 μg/g, superando en algunos casos el nivel máximo permitido para consumo de la población en general (0.5 μg/g). Las concentraciones más altas de mercurio total en peces fueron encontradas en los periodos de sequía en los cuales las temperaturas en la zona de estudio son altas y aumentan la actividad de metilación.

Published: February 2021

El objetivo fue determinar la estructura de mercado y los canales de comercialización del queso de hebra en el municipio de Vega de Alatorre, Veracruz desde el enfoque de Sistemas Agroalimentarios Localizados (SIAL). Se consultaron estadísticas oficiales, informantes clave, productores ganaderos y transformadores.  Los agentes que participan en la cadena en la estructura de mercado son proveedores, ganaderos, recolectores, queseros, comerciantes y consumidor final en cinco canales de comercialización que presentan información asimétrica,  prácticas oligopólicas, carente acción colectiva para una identificación territorial de dicho queso así como relación calidad-territorio que limitan la implementación de un SIAL en dicho municipio; a pesar de ser una actividad de importancia productiva y socioeconómica con un fuerte componente social que da anclaje de dicha actividad al territorio.
La originalidad de las civilizaciones axiales y el libre juego de la Historia
Authors: Roche Cárcel Juan A.
Published: February 2021

Este artículo intenta precisar, en primer lugar, hasta qué punto fueron originales las civilizaciones axiales producidas en torno al 500 antes de nuestra Era. Para ello, partiendo de una Sociología comprensivaweberiana y de los métodos heurístico social e histórico, se indagará en la etimología del concepto originalidad, que resulta básico en la creatividad y que remite, dialécticamente, a los términos aledaños de “origen” y “originario”. El primero supone, básicamente, un retorno al pasado y, el segundo una proyección hacia el futuro, algo que -como se verá- efectúa la Era Axial, uno de los momentos creativos más intensos de la historia de la humanidad. En segundo lugar, se tratará aquí la estrecha vinculación existente entre el juego y la creación de las utopías axiales y, con esta finalidad, se desarrollarán dos mapas conceptuales que delimiten los aspectos caracterizadores tanto de uno como de la otra. Después, se interrelacionarán dichas características a fin de encontrar las correspondencias de significado existente entre ellas y, finalmente, se concluirá desvelando tres fundamentos de la Era Axial útiles para comprender algunos de los problemas contemporáneos. Se comprobará, así, que la Era Axial es, ciertamente, original y que organiza una narrativa temporal muy creativa.
Las ambivalencias creativas del libro: del monoteísmo al fundamentalismo moderno
Authors: Gil-Gimeno Javier
Published: February 2021

Para Merlin Donald la aparición de los dispositivos de memoria externa es uno de los hitos creativos tras el desarrollo de la cultura teórica. El texto que presentamos analiza la evolución del papel desempeñado por uno de esos dispositivos, el libro, poniendo el acento en dos hitos: en el origen del monoteísmo abrahámico y en el fundamentalismo moderno. Para cumplir con nuestro cometido proponemos un análisis que se centra fundamentalmente en tres niveles: 1. En el que estudiamos cómo tanto la cultura escrita como el libro contribuyen al surgimiento de la cultura teórica y al desarrollo axial. 2. Nos detenemos en el tránsito del libro al libro sagrado y en su importancia para la aparición del monoteísmo abrahámico. 3. Analizamos el fundamentalismo religioso, tratando de dilucidar el papel que juega el libro sagrado en este fenómeno social. Una vez presentados estos niveles investigaremos el grado de creatividad vinculado con cada uno de ellos.
La deriva fundamentalista de lo creativo
Authors: Carretero Pasin Angel Enrique
Published: February 2021

En este trabajo se aborda cómo la creatividad se habría tornado en consigna apegada al marco ideológico de las sociedades de la modernidad avanzada, suponiendo la desaparición de su genuina autenticidad. Comienza aclarando que el sello ontológico diferencial encerrado en la creatividad designaría un acto de poiesis colectiva de una entidad hasta entonces inexistente. Luego, sopesa el porqué de las dificultades para su encaje en los marcos institucionales, así como las deficiencias de una hipótesis analítica desentendida de un enfoque dialéctico que pusiese de relieve las determinaciones en donde la creatividad se encuadra. Finalmente, se examina el marchamo fundamentalista adoptado por ésta en un doble escenario. Primero, constatando su elevación a un dogma de fe inductor de dinámicas institucionales y organizacionales configuradoras de nuevas subjetividades sociales. Segundo, haciendo ver la fetichización de la subjetividad resultante del carácter performativo asociado al encumbramiento de una singularidad y originalidad creativa.
Financiación, legalización y calidad en el cuidado de 24 horas en la vejez en Alemania: perspectivas e intereses
Authors: Horn Vincent
Published: February 2021

El mercado de cuidado de 24 horas para el cuidado en la vejez en Alemania es un sector complejo donde la falta de legalización y regularización ha dado lugar a un sistema con una gran proporción de empleo irregular y prácticas semilegales por parte de las agencias intermediarias. Hasta ahora el Estado se ha mantenido al margen de este fenómeno, cerrando los ojos ante la informalidad y las violaciones de derechos laborales y sociales en los hogares alemanes. Este artículo arroja luz sobre el funcionamiento de este sistema mediante el análisis de las perspectivas e intereses de varios actores involucrados en la perpetuación del mercado del cuidado de 24 horas: las familias, las agencias intermediarias y las asociaciones de bienestar. El artículo se basa en el análisis de datos cualitativos recogidos sobre los diferentes actores en el marco del proyecto “Emergence and Significance of Transnational Care Arrangements (ESTRANCA)”.
El giro pragmático en la sociología. De las sociologías americanas a la perspectiva político-moral de Boltanski
Authors: Nardacchione Gabriel
Published: February 2021

Este artículo busca definir los perfiles del enfoque político-moral, de la llamada sociología pragmática, que en Francia co-fundó Boltanski. Articularemos sus principales argumentos con algunas tradiciones pragmáticas de las que resulta heredera. La hipótesis del artículo es que este enfoque siguió el dictatum de un giro pragmático del lenguaje, que tuvo efectos sobre el interaccionismo simbólico, la etnometodología y hasta sobre la teoría de la acción comunicativa. En este sentido, el artículo destaca cincos aspectos de continuidad entre dichas perspectivas: i) el problema de la definición de una acción situada, ii) la influencia del carácter ordinario de las acciones, iii) el cumplimiento de reglas prácticas, iv) la incorporación del problema moral en un sentido práctico, y v) una articulación entre coherencia del lenguaje y consistencia con un mundo material.
Estandarizadores. La nueva burocracia privada que controla la calidad y la seguridad alimentaria en las cadenas globales agrícolas
Authors: De Castro Pericacho Carlos , Gadea Montesinos Elena , Sánchez García Miguel Ángel
Published: February 2021

La producción global agroalimentaria se encuentra estructurada en cadenas sobre las que los grandes grupos de distribución (marcas, supermercados) ejercen un estrecho control. En las últimas décadas, los estándares privados de calidad y seguridad se han convertido en una de las formas más importantes de gobernanza de estas cadenas. Nuestro objetivo es analizar la estructura institucional desde la que se diseñan estos requisitos de calidad y seguridad y los procedimientos de evaluación. La hipótesis que planteamos es que el poder de los grandes distribuidores aumenta gracias al control de esa estructura institucional, que denominamos régimen tripartito de los estándares (Loconto y Busch, 2010). Para dar cuenta de ello analizaremos los estándares privados mercantiles que predominan en una de las regiones exportadoras de frutas y verduras más importantes de Europa, la Región de Murcia. Mostraremos que el régimen tripartito de los estándares privados de los grandes distribuidores (Global GAP, IFS, BRC) presenta tres característicasprincipales: la hibridación de lo público y lo privado en el ámbito de la regulación; la burocratización por medio de profesionales expertos, conocimientos especializados y procedimientos procedentes de actores privados; y el control de los grandes distribuidores sobre todo el proceso de estandarización.
Los últimos y las últimas de la cadena. Calidad y trabajo en el sector citrícola valenciano
Authors: Torres Pérez Francisco , Pérez Alonso Yaiza
Published: February 2021

Los trabajadores y trabajadoras agrícolas ocupan la última posición en las cadenas globales agroalimentarias. Éstas, hegemonizadas por las grandes distribuidoras, trasladan de arriba a abajo una creciente presión competitiva en la que la calidad es un elemento central. Este artículo aborda las consecuencias que los requerimientos de calidad tienen sobre la mano de obra en La Ribera del Xúquer (Valencia), un territorio citrícola de exportación. Nuestros resultados indican que los estándares de calidad no suponen una mayor calidad de trabajo en el campo, aumentan las diferencias entre trabajadores y refuerzan la segmentación étnica. En los almacenes, tradicionalmente feminizados, los requerimientos de calidad si bien suponen una mayor polivalencia y control del espacio, comportamiento y cuerpo de la trabajadora, han contribuido a un cumplimiento más estricto del convenio colectivo.

Democracy Reloaded. Inside Spain’s Political Laboratory from 15-M to Podemos. Cristina Flesher Fominaya. Oxford: Oxford University Press, 2020
Authors: Lobera Josep
Published: February 2021

Diversas protestas sociales han tenido un papel disruptivo en la segunda década de este siglo, con formas que han puesto a prueba nuestra comprensión previa de los movimientos sociales. Algunas de ellas forjaron tipos poco convencionales de estructuras de movilización, como los llamados square movements. El último libro de Cristina Flesher Fominaya, publicado por Oxford University Press, realiza una revisión teórica amplia de lo que han supuestos estos movimientos a partir de su caso más significativo: el 15-M. Se trata de un libro ambicioso, empezando por su estructura organizada en cinco partes: democracia y 15-M; de la protesta a la ocupación; de la ocupación al movimiento; del 15-M a Podemos; y un capítulo final de conclusiones.
Milrinone in the treatment of Persistent Pulmonary Hypertension of the Newborn: A Case Series
Authors: Dera Norbert , Osinski Lukasz , Jurkowski Piotr , Doboszynska Anna , Szajda Slawomir , Minarowska Alina
Published: February 2021

Persistent Pulmonary Hypertension of the Newborn (PPHN) is defined as a
failure of the normal circulatory transition after birth. PPHN manifests
as a progressive and potentially fatal hypoxemic respiratory failure.
The condition is associated with a persistent increase in pulmonary
vascular resistance and reduced blood flow in the pulmonary vessels
without an accompanying congenital heart defect. The abnormalities in
pulmonary circulation lead to right-to-left shunting through the foramen
ovale and usually also through the ductus arteriosus, with resultant
hypoxemia, which manifests clinically as cyanosis. Management options in
PPHN include optimal lung inflation, oxygenation, prevention of
acidosis, stabilization of blood pressure, sedation and pulmonary
vasodilator therapy. While inhaled nitric oxide (iNO) is the most
commonly used treatment option, alternative methods can be used whenever
is unavailable or contraindicated. We report three cases of severe PPHN,
in which due to the lack of adequate response to intravenous MgSO4, the
patients were switched to milrinone.
Kinetics and Thermodynamics of CO Oxidation by (TiO2)6
Authors: Kaur Navjot , Goel Neetu , Springborg Michael , Molayem Mohammad
Published: February 2021

Molecular level insights into the mechanism and thermodynamics of CO
oxidation by a (TiO) cluster have been
obtained through density functional calculations. Thereby, we have
considered as an example, two different structural isomers of
(TiO) with the purpose of
understanding the interplay between local structure and activity for the
CO oxidation reaction. Active sites in the two isomeric forms were
identified on the basis of global and local reactivity descriptors. For
the oxidation of CO to CO2 we considered both sequential and
simultaneous adsorption of CO and O2 on (TiO2)6 cluster through the ER
and LH mechanisms, respectively. Three different pathways were obtained
for CO oxidation by (TiO2)6 cluster, and the mechanistic route of each
pathway were identified by locating the transition-state and
intermediate structures. The effects of temperature on the rate of the
reaction was investigated within the harmonic approximation. The
structure-dependent activity of the cluster was rationalized through
reactivity descriptors and analysis of the frontier orbitals. Finally,
we also considered the effects of a support, i.e., graphene, on the
oxidation mechanism.

In this paper, we establish fixed point theorems for generalized nonlinear
contractive mappings using the concept of w-distance on metric spaces
endowed with an arbitrary binary relation. Our fixed point theorems
generalize recent results of Senapati and Dey [ J. Fixed Point Theory Appl.,

literature. Moreover, in order to revel the usability of our findings an
example and an application to first order periodic boundary value problem
are given.
Glucose Control, Sulfonylureas, and Insulin Treatment in Elderly People With Type 2 Diabetes and Risk of Severe Hypoglycemia and Death: An Observational Study
Authors: Ling Suping , Zaccardi Francesco , Lawson Claire , Seidu Samuel I. , Davies Melanie J. , Khunti Kamlesh
Published: February 2021

OBJECTIVE

To estimate the relative and absolute risk of severe hypoglycemia and mortality associated with glucose control, sulfonylureas, and insulin treatment in elderly people with type 2 diabetes.

RESEARCH DESIGN AND METHODS

We identified elderly subjects (≥70 years old) with type 2 diabetes between 2000 and 2017 in the U.K. Clinical Practice Research Datalink primary care database with linkage to hospitalization and death data. Subjects with three consecutive HbA1c values <7% (53 mmol/mol) while on insulin and/or sulfonylureas within 60 days prior to the third HbA1c value (exposed) were matched with subjects not exposed. Hazard ratios (HRs) and absolute risks were estimated for hospitalizations for severe hypoglycemia and cardiovascular and noncardiovascular-related mortality.

RESULTS

Among 22,857 included subjects (6,288 [27.5%] exposed, of whom 5,659 [90.0%] were on a sulfonylurea), 10,878 (47.6%) deaths and 1,392 (6.1%) severe hypoglycemic episodes occurred during the follow-up. In comparison with nonexposed subjects, the adjusted HR in exposed subjects was 2.52 (95% CI 2.23, 2.84) for severe hypoglycemia, 0.98 (0.91, 1.06) for cardiovascular mortality, and 1.05 (0.99, 1.11) for noncardiovascular mortality. In a 70-, 75-, 80-, and 85-year-old subject, the 10-year risk of severe hypoglycemia was 7.7%, 8.1%, 8.6%, and 8.4% higher than in nonexposed subjects, while differences for noncardiovascular mortality ranged from 1.2% (95% CI −0.1, 2.5) in a 70-year-old to 1.6% (−0.2, 3.4) in an 85-year-old subject. Sulfonylurea and insulin use were more relevant predictors of severe hypoglycemia and death than were glucose levels.

CONCLUSIONS

Elderly subjects with type 2 diabetes and low HbA1c on sulfonylurea or insulin treatment experienced a substantially higher risk of hospitalization for severe hypoglycemia but had no clear evidence of increased risks of mortality.
Fleksibilitas Tradisi Pesantren Terhadap Kekerasan Pada Isteri (Studi Kasus Pada Penerapan UU PKDRT Di Lingkungan Pesantren Kab. Jombang)
Authors: Hyma Puspytasari Heppy
Published: February 2021

Komunitas pesantren sebenarnya telah lama mengetahui isu kekerasan dalam rumah tangga (KDRT), namun bukan berarti mereka benar-benar memahami makna KDRT secara menyeluruh. Karena realitanya, KDRT itu sendiri tersembunyi dalam dunia rumah tangga pesantren. Hal - hal lain yang mungkin juga menjadi penyebab terjadinya KDRT di pesantren adalah patron kyai sebagai pemimpin pesantren yang tidak dapat digoyahkan oleh apapun. Banyak fakta yang juga mendukung bahwa perkataan kyai adalah selalu benar dan tidak pernah salah, karena beliau dianggap paling memahami ajaran agama. Selain itu juga keberadaan ayat yang menyatakan tentang nusyus nya seorang istri, dan pembelajaran keluarga yang disebutkan “boleh memukul” diartikan secara harfiah. Kondisi tradisi dalam pesantren yang demikian khusus dan adanya kontroversi antara tradisi dalam pesantren dengan UU PKDRT menjadikan hal ini menarik untuk diteliti lebih lanjut. Tujuan penelitian ini adalah untuk mengetahui: Apakah tradisi pesantren memicu adanya KDRT dan bagaimana alternatif penanggulangan KDRT di pesantren Pendekatan yang digunakan dalam penelitian ini adalah pendekatan socio legal research yaitu melalui pendekatan ini hukum juga dikonsepkan sebagai gejala sosial yang empiris yaitu dalam tindakan aksi dan interaksi warga masyarakat sehari-hari, bukan hanya sebagai UU ataupun putusan hakim saja. Hasil penelitian ini bahwa tradisi pesantren tidak memicu adanya KDRT meskipun dimungkinkan ada ketimpangan gender dalan relasi suami isteri tetapi tradisi di pesantren malah lebih memberikan pembelajaran yang mendukung emansipasi maupun kesetaraan gender tanpa meninggalkan norma agama. Sedangkan alternative penyelesaian penanggulangan KDRT di pesantren tidak diadakan karena belum ada kejadian yang merujuk pada KDRT, namun untuk mencegah adanya KDRT, pesantren juga menyumbangkan peran melalui pendekatan Pendidikan bagi para santri, yaitu Pendidikan relasi suami dan isteri yang adil dan mengakui kesetaraan namun tetap dalam bingkai ajaran agama Islam, sesuai kodrat masing-masing dengan tetap saling bantu dalam segala bagian rumah tangga.

Published: February 2021

Purpose: This study aims to test the models established for the mediating role of empathy in the relationship between parental attitudes and altruism in high school students.Design/Methodology/Approach: The study was carried out with 401 participants [224 (55.9%) girls and 177 (44.1%) boys, age- range: = 14-20, Mage = 16.46 years] who are students from various Anatolian/Science High Schools in Elazığ. As a measurement tool, the “Empathy Tendency Scale,” “Parenting Attitude Scale,” and “Altruism Scale” were used. The data of the study were analyzed with structural equation modeling (SEM). In addition, the bootstrapping process was used to test the significance of the indirect effect.Findings: Two models were determined within the framework of the structural equation model. It is determined that the model which states empathy as the partial mediation role between democratic, full mediation role between protective, authoritarian, attitudes of parents and altruism is the best model. After bootstrapping process, the indirect effects were seen as significant. The findings were discussed in the related literature, and suggestions were made for future researchers and educators.

The Prevalence of Problematic Mobile Phone Use amongst EFL Learners in Turkey
Authors: ÖZER Ömer
Published: February 2021

Despite the many benefits attributed to mobile phones in nearly all aspects of everyday life, concern over the problematic use of these smart devices has grown. This study investigates the prevalence of problematic mobile phone use in a sample of Turkish undergraduate EFL learners. Additionally, it verifies whether this particular assessment was equally applicable to male and female students in different age groups. Problematic mobile phone use was assessed using a mobile phone addiction scale. After employing non-random convenience sampling, 267 students responded to the survey. The results showed that neither age nor gender had a significant effect on mobile phone addiction levels. Furthermore, the prevalence of problematic and at-risk mobile phone users constituted 19.8% of the study population and an overwhelming majority of the problematic mobile phone users were females, which indicated that they could potentially be considered as addicted to mobile phones. The implications of these findings for classroom practices and for the more inclusive language-learning environment are discussed.
Issues of ‘Authenticity’ and Apocalyptic Thought in an Indigenous Religious Response to Colonisation
Authors: Moon Paul
Published: February 2021

The traditional/colonial dichotomy dominates much of the discourse on New Zealand’s indigenous Māori society in the nineteenth and early twentieth centuries.  However, this binary distinction can often be more nuanced in practice, and in the case of certain indigenous religious responses to colonisation, can potentially obscure as much as clarify the nature of Māori society in this era.  The often overlapping rather than colliding forces of the traditional and colonial worlds can be seen in religious movement led by the Māori prophet and leader Rua Kēnana (1869-1937) in the early twentieth century. 

To a people that looked to be on the brink of disappearing, Rua offered the vision to his Māori followers of a utopian future (which was partly a re-fashioned image of a very vague, idealised nostalgic past) that would be achieved after the country endured various apocalypses.  Rua developed his religious and prophetic movement which at its height attracted over a thousand adherents, and which anticipated rather than feared the apocalypses he prophesied because of the potential these followers felt it held for transforming their lives.  What is apparent in the history of this movement is the role of colonisation as a causative and correlative element in the rise of apocalyptic religious sects, and how notions of authenticity can be interpreted in various ways when viewed through the optic of the group being colonised.  Nether the category of traditional nor colonial applies to Rua’s sect, and paradoxically, its hybridity was the source of its authenticity.  The fact that it was not purely traditional or simply a transposition of settler religion is what made it authentic to Rua’s followers in a period when the certainties of the pre-European world in a state of flux, but where the world of settler society was still largely out of reach. 

This paper examines the origins of Rua’s sect, and how he relied increasingly on prophecies of an imminent apocalypse in order to bolster support among followers. In the course of this survey, themes of religious authenticity, the significance of cultural innovation, the role of charismatic leaders to the success of hybridised sects, and the importance of apocalyptic thought to communities in crisis are explored.  What emerges from this analysis is that the tensions and dislocations of those indigenous communities in New Zealand subject to extensive colonisation was sufficiently extreme that some members of these communities sought supernatural deliverance (with the implication that the saw little prospect of temporal solutions to their situations). What is also at least circumstantially evident is that the traditional Māori world no longer fully met the religious needs of some of these communities, but to a similar extent, neither did the religious denominations of settler society either. It was in the contested space in between were movements such as those led by Rua temporarily flourished.

Since Indonesia as a developing country which consists of 87.2% of Muslim citizens, sharia insurance plays an important role. However, this presence of sharia insurance does not show significant growth compared to Malaysia. This study aims to determine whether efficiency may serve as an intermediary variable in linking market share and company size to the profitability of Islamic insurance in Indonesia. It employs secondary data to collect data by involving 11 sharia insurance companies with 4 years ranging from the year 2014 to 2017. The collected data were analyzed through Path analysis and Sobel test with the DEA VRS as an indicator of efficiency. In analyzing the collected data, the Path equation has passed the classic assumption test. The findings reveal that the market share and company size have respectively significant positive and negative influences on efficiency. It indicates that market share is a variable that shows a significant positive effect on profitability compared to the other two variables. Whereas, the results of Sobel tests show that efficiency cannot serve as an intermediary in this research model

Published: February 2021

The article discusses the problems of activation of the surface of the leather tissue by laser exposure, changes in the morphology of the surface of the leather tissue during laser processing, and subsequent covering dyeing of the leather. It is shown that laser treatment changes the structure of the surface of the leather tissue, the bundles of collagen fibers are split, the structure becomes loose, which increases the diffusion of the coating dye reagents, and their reactivity increases without chemical modification. In the process of grinding leather fabric, it is finely cleaned which improves adhesion of the coating paint to the surface of the leather fabric, which improves the quality of leather fabric products. It was shown that laser exposure under the conditions found (pulses with an interval of 3 μs, a duration of 10 ns) does not cause destruction and configuration changes in collagen.

Considering the high content of oil and complex residual additives in leather samples, a new analytical method based on the solid-phase extraction technique and gas chromatography-selected ion monitoring mass spectrometry (GC-SIM-MS) was developed to determine 24 organic compounds involving the organochlorine pesticides (OCPs), organophosphorous pesticides (OPPs) and pyrethroids pesticides residues in leather. The extraction conditions (such as the extraction solution, purification procedure and solid-phase extraction column) were optimized using the positive leather samples based on the recovery rates of the pesticides. The best extraction solution, solid-phase extraction column and chromatography column were n-hexane and ethyl acetate (1+1, volume) mixed solution, Carb-PSA (1.0 g, 6mL) and DB-1701 (length: 30 m, inside diameter: 0.25 mm, film thickness: 0.25 μm). The optimized extraction time and temperature were 20 min and 25°C, respectively. The detection limits of 24 pesticide residues range from 0.05 to 0.10 mg/kg, and the recoveries range from 74% to 116%. The relative standard deviations (RSD, n=6) range from 5.42% to 12.00%. The developed method presented a simple, rapid, sensitive, and inexpensive method to detect 24 pesticides in skin and leather and was successfully applied to the detect them in leather products (cowhide, sheep leather and pig leather).
