Published: January 2021

Hizmet başarısızlıklarının neden olabileceği olumsuzluklardan kaçınmak, başarılı hizmet telafileri sunmakla mümkündür. Başarısızlık sonrası yapılan telafilerin, müşteriler tarafından nasıl değerlendirildiğinin anlaşılması işletme yöneticileri için önemlidir. Müşterilerin, yaşanan bütün başarısızlıklar karşısında hizmet telafilerine verdikleri tepkilerin birbirinin aynı olması beklenmemelidir. Özellikle başarısızlığın büyüklük düzeyi hizmet telafilerinin değerlendirilme sürecinde önemli bir faktördür. Bu çalışmanın amacı, algılanan adalet boyutlarının telafi tatminine etkisi üzerinde başarısızlığın büyüklüğünün düzenleyici etkilerini ortaya koymaktır. Bu kapsamda araştırma amacı doğrultusunda deneysel bir tasarım oluşturulmuştur. Araştırmaya 723 kişi katılmış ve araştırma kapsamında belirlenen hipotezler hiyerarşik regresyon analizi ile test edilmiştir. Analiz sonuçlarına göre, prosedürel ve dağıtımsal adaletin telafi tatmine etkisinin başarısızlığın büyüklüğüne göre farklılaştığı ortaya konmuştur.

Authors: Handayani Fitria , Setyowati Setyowati , Pudjonarko Dwi , Sawitri Dian Ratna
Published: January 2021

Background: There are several factors that contribute to Post Stroke Depression (PSD). Since a single intervention is proven ineffective to deal with PSD, an intervention which includes biological, psychological, social, and spiritual aspects (“SELF-HELP Packages”), therefore, needs to be established.Purpose: The purpose of the study was to investigate the effect of “SELF HELP Packages” intervention on PSD among ischemic stroke survivors after three months from onset and its effect after confounding variables were controlled.Methods: This study was a pre and post quasi-experiment with a control group involving 34 ischemic stroke survivors each group. The inclusion criteria were survivors after three months from ischemic stroke, no aphasia, having a good hearing, and having Mini Mental Status Examination (MMSE) score of ≥ 22. GRID-HAMD 17, Multidimensional Scale of Perceived Social Support (MSPSS), and Barthel-Index were used to measure PSD, social support, and functional status respectively. “SELF-HELP Packages” intervention was delivered in three sessions, namely information delivery, discussion and activity. Statistical analyses were conducted using McNemar test, Chi-square and logistic regression.Results: The result showed that “SELF-HELP Packages” considerably decreased PSD in the intervention group (p=0.004). There were also significant differences in PSD after the intervention between two groups (p=0.008). Logistic regression showed that ‘SELF-HELP Package” had no effect on PSD when other confounding variables were controlled (p=0.075, OR=0.288, 95% CI 0.073 – 1.135).Conclusion: SELF-HELP Packages” should be applied in providing the nursing intervention among stroke ischemic survivors in clinical setting. A longer period of time for the intervention is also recommended for the next study in order to obtain a more robust result.
Test Apparatus for Rapid Determination of Soil-Water Retention Curve under Isotropic Loading Condition
Authors: Roy S. , Rajesh S.
Published: January 2021

In the present study, a custom-designed test apparatus comprising a plexiglass cell chamber with a base pedestal to accommodate a cylindrical soil sample with the water potential and volumetric water content sensors was developed to measure the soil-water retention curve (SWRC) of unsaturated soils under isotropic loading condition. The developed test apparatus is capable of rapidly measuring isotropic stress-dependent SWRC utilizing preequilibrated unsaturated soil samples. The methodologies for obtaining normalized volumetric and gravimetric stress-dependent SWRC using continuous and spot measurements were discussed in detail. In addition, the need for the soil-specific sensor calibration was illustrated, and an alternate method of developing calibration curves for sensors was discussed. To understand the efficacy of the developed apparatus, stress-dependent SWRC for two different statically compacted low-plasticity clays at isotropic confining pressures of 10, 100, and 200 kPa were evaluated. The stress-dependent SWRC obtained from the developed test apparatus is in good agreement with the results obtained from the suction-controlled triaxial test apparatus, which proves the ability of the developed apparatus to replicate stress-dependent SWRC without involving the axis translation technique. In addition, the apparatus can also be used to obtain the void ratio of unsaturated soil under various isotropic confinements at constant water content. Hence, the developed test apparatus has the potential to simulate both water content and void ratio surfaces with respect to suction under rapid isotropic loading condition, which can be used for constitutive modeling in unsaturated soils.
Deep, In Situ Nonlinear Dynamic Testing of Soil with Controlled Blasting: Instrumentation, Calibration, and Application to a Plastic Silt Deposit

Published: January 2021

This study presents a novel test method to obtain dynamic properties of soil in situ using controlled blasting. Experimental and calibration protocols have been developed to conduct such investigations for any soil at any depth to obtain the coupled response between nonlinear shear modulus and pore pressure generation in soil. Controlled blasting using buried explosives with different charge weights at various depths were used as an active seismic source and the soil response measured. Micro electro mechanical system (MEMS) accelerometers, geophones, pore pressure transducers, and the MEMS-based inclinometers were calibrated to develop unique excitation voltage-to-unit relationships. Procedures to determine the post-installation sensor locations and orientations were developed to quantify the appropriate body wave velocity and shear strain in the soil. The conversion of calculated strains to a constant-volume direct simple shear-equivalent shear strain facilitated direct comparison to previously reported shear modulus reduction curves. Although this manuscript primarily focuses on instrumentation and calibration protocols, an example of the results of a test blast program is provided to demonstrate observation of the in situ, coupled, nonlinear fluid-mechanical response of an instrumented plastic silt deposit at a depth of 9 to 11.5 m below ground surface.

Authors: Liu Shiyu , Dong Bowen , Yu Jin , Cai Yanyan
Published: January 2021

Calcareous sand is widely distributed on the continental shelf and along the coast and has a low mechanical strength and a high compressibility. The use of biostimulation to activate and enrich ureolytic bacteria induces mineralization to strengthen calcareous sand and has the advantages of being environmentally friendly and less expensive than alternatives. In this study, reinforcement tests and evaluations of calcareous sand columns were carried out to study the effects of different biostimulation schemes on reinforcement. First, six different biostimulation schemes were used to stimulate and enrich ureolytic bacteria in calcareous sand, and the number of bacteria, pH, and urea concentration in the sand columns were biochemically monitored. Then, calcium ions were introduced into the sand columns to induce calcium carbonate precipitation. Finally, the reinforcement effect was evaluated according to the results of mechanical property tests, including mineralization product detection and microbial community change analysis, of the calcareous sand. The results show that (1) the concentrations of yeast extract (YE) and NH4Cl in the biostimulation scheme can significantly affect the stimulation results, in which the best conditions are a YE concentration of 0.2 g/L, an NH4Cl concentration of 100 mM, and an initial pH value of 9.0; and (2) the greater the content and distribution of newly formed calcium carbonate in calcareous sand is, the better the reinforcement effect is. In addition, biostimulation changed the microbial community composition in the calcareous sand, making ureolytic bacteria the new dominant population, which is more conducive to urea decomposition and calcium carbonate formation.

Authors: Araújo Sofia
Published: January 2021

Em qualquer contexto literário distópico –obra total ou moldura diegética de uma contra-proposta utópica– a figura do último homem, do indivíduo só, do único sobrevivente, assume-se comummente como o guardião do que foi e toma para si um papel civilizacional. A partir da análise de três romances profundamente distintos -The Last Man, de Mary Shelley (1826), O Quase Fim do Mundo, de Pepetela (2013) e O Último Europeu 2284, de Miguel Real (2015)- foi possível delinear os pontos cardiais destas figuras literárias, mas também filosóficas, e confirmar que a figura querida dos românticos mantém a plasticidade e o potencial sugestivo de antanho.

Influencia del Programa Comportamiento Seguro en los Trabajadores de Planta Callao -CLSA, Lima-Perú
Authors: Rodríguez Del Carpio César
Published: January 2021

Los programas de seguridad basados en el comportamiento se aplican con la finalidad de reforzar el nivel de seguridad en el trabajo, pero si se hace por cumplir con un número de observaciones de comportamiento seguro establecidas en la meta del mes en el lugar de trabajo, genera en los trabajadores que solo cumplan con la seguridad mientras se les está observando o que los observadores reporten comportamientos que realmente no vieron; en consecuencia, los accidentes con trabajadores continúan y peor aún con casos fatales, los observadores dejan de creer en el programa de seguridad que están utilizando y la dirección llega a creer que con un mayor número de observaciones se logra corregir los comportamientos inseguros; por ello es que los resultados del programa no se alcanzan con el tiempo. Esto es consecuencia de no haber entendido los principios de la teoría de la seguridad basada en el comportamiento desde el inicio de su implementación. En la presente investigación se aplicó la teoría de la seguridad basada en los comportamientos para definir la tarjeta de observadores y para realizar las intervenciones con refuerzo positivo de manera eficiente. Así, el estudio se orientó a encontrar si hay diferencia significativa entre las observaciones de comportamiento seguro antes que el observador realice la retroalimentación con refuerzo positivo y las observaciones después de cada intervención, para ello se tomó sólo el número de observaciones seguras con el propósito de conocer el efecto que tiene la retroalimentación con refuerzo positivo que se da en la observación de comportamientos seguros en el periodo de estudio. Se encontró que hay diferencia significativa en los comportamientos seguros después de realizar la retroalimentación para un nivel de confianza del 95% y una reducción del 85.7% de accidentes incapacitantes en el periodo de estudio.

Authors: Filho José Tarcísio Oliveira
Published: January 2021

O artigo reflete e problematiza as perspectivas teóricas que se propõem a organizar e a conceituar os jornalismos locais e regionais, como as oriundas da Geografia, da Comunicação e da Sociologia. A noção de proximidade é discutida enquanto uma relação entre o usuário e os espaços televisivos de noticiários regionais. Com o intuito de refletir sobre sua aplicação na empiria, são desenvolvidos quatro operadores analíticos: canais de participação, espaço cênico, editorias/temáticas e retórica da transmissão direta. A análise foi realizada por meio da visualização de 12 edições do Praça 1 MG1 da TV Integração Zona da Mata e Campo das Vertentes de Minas Gerais. Foi identificado que a performance dos jornalistas, a organização das editorias, o efeito de presente constante e a inclusão de valores culturais que perpassam pela sociedade atuam como demarcadores simbólicos nas relações de proximidade do telejornal regional.

Introducción. La evaluación y selección de cereales de grano pequeño para sistemas de producción de rumiantes promueven sistemas de producción eficientes. Sin embargo, es necesario evaluar la diversidad presente en bancos de germoplasma nacional, para reconocer accesiones con atributos sobresalientes. Objetivo. Evaluar la respuesta agronómica y nutricional en el forraje de accesiones de cereales de grano pequeño. Materiales y métodos. Entre junio y diciembre de 2018, en el centro de investigación Tibaitatá de la Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA), Mosquera, Colombia, se establecieron veintiséis accesiones de cebada (Hordeum vulgare) y veinticinco de trigo (Triticum sp.). Cuatro repeticiones de cada material se sembraron en un surco de 5,0 m con distancia de 0,2 m entre plantas. Durante el periodo fenológico del cultivo se evaluaron quincenalmente: altura, vigor, presencia de plagas y enfermedades, número de tallos por planta y hojas por planta. Cuando el 50 % de las plantas de cada variedad alcanzaron los estados de vaina engrosada o de grano lechoso-pastoso, se cosecharon dos plantas por surco, y se determinó la proporción de tallos, hojas y espiga, producción de materia seca y concentración de nutrientes. Las variables evaluadas quincenalmente se analizaron con un modelo de bloques con medidas repetidas, mientras las demás se analizaron con un modelo de bloques al azar. Resultados. A mayor edad del cultivo se presentaron mayor altura de la planta, relación tallo: planta, presencia de enfermedades y menor vigor. Durante el periodo de vaina engrosada las accesiones C7 y T24 presentaron la mayor (p<0,05) producción de biomasa, mientras que en el estado de grano lechoso-pastoso fue el material T24 (p<0,05). Conclusión. Las accesiones C7, C17 y C20 de cebada, y las T12, T15 y T24 del trigo presentaron características productivas y nutricionales con potencial para ser evaluados en futuros trabajos de investigación.
Frecuencia de fotogramas óptima para evaluar la cinética espermática de verracos con un sistema CASA-Mot
Authors: Barquero Vinicio , Víquez Luis , Calderón Calderón Josué , Valverde Anthony
Published: January 2021

Introducción. La movilidad es el indicador de calidad seminal más utilizado, por tanto, es necesario determinar una adecuada frecuencia de fotogramas (frame rate, FR) para estandarizar los análisis cinéticos con los equipos de análisis computadorizado de semen (CASA-Mot) y disminuir la variabilidad entre laboratorios, lo que optimizará el número de dosis seminales y su calidad para la industria porcina basada en inseminación artificial (IA). Objetivo. Determinar la frecuencia óptima de fotogramas sobre la cinética espermática de verraco mediante un sistema comercial CASA-Mot y analizar la distribución de subpoblaciones espermáticas con el FR óptimo. Materiales y métodos. Se utilizaron veinte dosis seminales de diez verracos Pietrain (Sus scrofa domestica). El periodo experimental fue entre febrero y julio del año 2017. Se utilizó el sistema CASA-Mot (ISAS®v1) con cámaras de recuento ISAS®D4C20 precalentadas a 37 °C. El tiempo de captura fue de dos segundos. Resultados. La frecuencia de fotogramas afectó los parámetros de cinética espermática, exceptuando la velocidad rectilínea (VSL), debido a que no representó un comportamiento dependiente del FR. Las demás variables presentaron alteraciones significativas al cambiar su FR, y la velocidad curvilínea (VCL) y velocidad promedio (VAP) fueron las variables más sensibles al cambio. Se obtuvieron tres componentes principales (PC) definidos por patrones de movilidad, progresividad y oscilación, en donde el PC1 (velocidad-ondulación) fue el más influyente, debido a que representó el 51,34 % y 55,08 % de la varianza total explicada para 25 y 200 fps (fotogramas por segundo), respectivamente. Conclusión. La frecuencia óptima de fotogramas para analizar variables de cinética espermática en verraco con un sistema CASA-Mot fue de 200 fps. Una tasa de fotogramas inferior provoca errores en la estimación de la trayectoria de los espermatozoides. La distribución de subpoblaciones espermáticas varía según la tasa de fotogramas utilizada. Es necesario establecer un protocolo de análisis para homogenizar los resultados.
¿Comer como el discurso médico-nutricional manda? Discursos y prácticas sobre alimentación saludable en sectores medios de la ciudad de Buenos Aires, Argentina.
Authors: Demonte Flavia Carolina
Published: January 2021

Objetivos: describir y analizar los discursos sobre alimentación saludable y su relación con las prácticas declaradas de integrantes de hogares con hijos/as que pertenecen a los sectores medios y que residen en la Ciudad Autónoma de Buenos Aires. Métodos: se utilizó un enfoque cualitativo, un tipo de estudio exploratorio-descriptivo y la técnica de relevamiento de la información fue la entrevista semiestructurada. Se seleccionaron intencionalmente 12 hogares pertenecientes a sectores medios que residen en la Ciudad Autónoma de Buenos Aires, integrados por parejas con hijas/os de diferentes edades. El procesamiento y análisis de la información fue realizado mediante la estrategia de análisis temático cualitativo. Resultados: se evidencia un discurso homogéneo sobre lo que se considera alimentación saludable, en función de las recomendaciones alimentarias vigentes independientemente de la edad y de vivir o no con sus hijos/as. Así como, una diversidad de prácticas de compra, preparación y consumo de alimentos. Esta diversidad se explica por la presencia de otros criterios que compiten con la búsqueda de alimentación saludable. Aunque se reconoce el efecto preventivo de la alimentación en relación con los problemas de salud asociados a esta, como el sobrepeso y la obesidad, emergen como los más enunciados y las explicaciones se asocian con la responsabilidad individual. Dos son las consecuencias más visibles de la divulgación y penetración del discurso médico-nutricional: reenviar al ámbito individual las prácticas alimentarias y del cuidado del cuerpo y omitir el peso del contexto y la responsabilidad colectiva en la explicación de los problemas de salud asociados con la alimentación actual.

Published: January 2021

Introducción: El acceso de las personas migrantes venezolanas al sistema de salud es fundamental para su supervivencia y bienestar futuro. El objetivo de esta investigación es analizar los niveles de afiliación a dicho sistema de las personas venezolanas en las áreas urbanas de Colombia por periodos de arribo, así como los factores sociodemográficos y laborales asociados. Metodología: Se realiza análisis cuantitativo de tipo estadístico descriptivo e inferencial, a partir de la Gran Encuesta Integrada de Hogares 2018, la cual aporta datos representativos para Colombia y sus 13 ciudades más importantes. Se utilizan los módulos de migración, de variables sociodemográficas del hogar y de ocupación relativos a la población de 14 a 65 años. Resultados: Únicamente 24,5 % de dichos migrantes están inscritos al sistema de salud en contraste a 93 % de las personas colombianas. Los niveles de afiliación se redujeron de 82 % entre las personas venezolanos que arribaron en 2013 o antes a 10 % entre los que llegaron en 2017-2018. Las personas venezolanas afiliadas al sistema de salud son una población selecta en términos sociodemográficos; más joven, más educada, con mayor participación laboral y mayores ingresos que la población nativa en Colombia. La baja inserción de las personas migrantes venezolanas en empleos con contrato escrito restringe dicha afiliación. Conclusiones: Las personas venezolanas en Colombia tienen muy limitada la inscripción al sistema de salud. A pesar de que este es un derecho protegido por los marcos jurídicos internacional y nacional, estas personas enfrentan barreras económicas, políticas y sociales para ejercer ese derecho en Colombia.

Authors: Penkov D. , Petkova M. , Petkova P.
Published: January 2021

Aim: To establish the effect of the new for Bulgaria probiotic ProMixAn Forte® in discontinued treatment of mule ducks for the first 28 days, when reared up to 72 days of age. Material and Methods: A research study was carried out with two groups of 50 female ducks each. The ducks were reared under a three-phase feeding regime, given the same feed, the forage of the experimental group being supplemented with the probiotic from 1 to 28 days of age (starter), after which the probiotic was stopped. Results: After 14 days, the experimental ducks showed significantly higher weight gain (5% – 9% in average for the separate periods), the tendency continuing for 15 days after stopping the probiotic (43 days of age), after which the weight gain decreased by more than 4 times compared to the control group. After 56-th day of age, the experimental ducks had a higher growth rate than the control, but they could not compensate for the lag. At the end of the period, the experimental fowl showed 17% lower final live weight compared to the untreated. The results of the feed conversion ratio (FCR) to produce a kg of live weight were analogous, but opposite in value. FCR was 8 to 13% lower in the experimental birds from 14 to 43 days of age, over 4.5 times higher from 43 to 57 days and 40% lower from 57 to 72 days, thus the negative results in the previous period were compensated. The differences in the separate periods were statistically significant.
Conducted microbiological examination of caecum and fresh droppings showed that on the day of discontinuing the probiotic treatment, the ratio of lactic acid to coli bacteria in the experimental group was in favour of the genus Lactobacillus, while 4 weeks later it changed in favour of the coli bacteria.

Numerical results for Cu (fcc), W (bcc) and Zn (hcp) agree well with the measured values. Debye-Waller factors in X-ray absorption fine structure (XAFS) and equation of state computed using the obtained Morse potential parameters agree well with the experimental results.

Properties of the axion in PQWW model is considered. In this model, axion appears as a new phase of the Higgs field. From a general Higgs potential which is renormalizable and invariant under UPQ(1) transformation, we consider the interaction of the axion with leptons and quarks. Based on these results, axion production in e+e- collision is calculated in detail. The numerical evaluation shows that the axion can be detected in

experimental conditions.

The squareness factor, defined as the ratio BH c / i H c , plays very importance role. This factor reflects the magnetization process under a reversed magnetic field in magnet. So the factor can be used as the critical parameter for estimating the magnet quality. For the powder compaction of 6.48 g/cm 3 mass density, if is less than 0.48 then the preparation conditions were far from the optimal ones. The value higher than 0.48 of factor proves that in prepared powder the coupling between grains is enhanced. From the theory and the experiments it was proved that for full dense compaction of NdFeB Stoner-Wohlfarth particles the squareness factor and the maximum energy product(BH)max can not be lager than 0.53 and 10.7 MG. Oe, respectively.

Türk şiirinde ilk örnekleri 12-14. yüzyıllarda Hâce Ahmet Yesevî, Yûnus Emre, Âşık Paşa, Gülşehrî gibi mutasavvıflarca verilmeye başlanan Tekke şiiri, 15. ve 16. yüzyıllarda büyük bir gelişme göstererek Eşrefoğlu Rûmî, Kaygusuz Abdal, İbrâhim Gülşenî, Üftâde, Şemseddin Sivâsî, Pîr Sultân Abdal ve daha nice şairle tekâmül etmiş ve 17. yüzyılda Azîz Mahmûd Hüdâyî, Abdülmecîd Sivâsî, Sinân Ümmî ve Niyâzî-i Mısrî vb. şairlerle gelişimini tamamlamıştır. Bu süreçlerde şiir, tasavvufla iştigal edenlerin düşüncelerini yayma araçlarından biri olmuş ve ilâhî coşkuya kapılma, rûhî hazzı tatma ve Hak’tan gayrı her şeyden alakayı keserek vecde gelme vasıtası olarak sûfîlerin meclislerinde ve dinî âyinlerinde zevkle okunup dinlenir bir mahiyet kazanmıştır. Devlet-i Âliyye’nin kudretini yitirmeye başladığı 18. yüzyılda ise gerilemeye paralel olarak sanatsal faaliyetlerde, bu faaliyetlerin başını çektiği şiirde duraksama ve tekrar dönemine girilmiştir. Tekke şiirinin işte böyle bir inhitat devrinde akranları arasından bir adım öne çıkan temsilcisi Ünsî Hasan Şa'bânî, şiir terennüm eden şair ve mutasavvıf olarak 18. yüzyıldaki seçkin yerini almıştır.Bu makalede Halvetiyye tarikatının Şa'bâniyye koluna mensup bu istidatlı şairinin yaşamı, edebî kişiliği ve Divân’ının hususiyetleri belirtildikten sonra Divân’ında yer alan 424 adet şiirinden hareketle Kur’ân-ı Kerîm’de zikrolunan peygamberler hakkındaki tasavvurları tahlil edilecektir. Şiirlerinde şekilden ziyade manâya önem vermiş olan ve tasavvufî sembolik dili gayet başarılı bir şekilde kullanan Ünsî’nin hangi peygamberi ne cihetle kaç defa zikrettiği de tespit edilip peygamber sevgisi ortaya konulmaya çalışılacaktır.

Background In most African countries, the elderly face challenges that affect their health and wellbeing and are more pronounced because of the systemic factors of inadequate health care, food insecurity and the general care. Increasing population of the elderly persons in Uganda is raising concern than ever before. The purpose of this paper to ascertain care available to the rural elderly persons and their role as carers for their grandchildren and implications on their wellbeing. Methods This was a qualitative study conducted among the rural elderly aged 60 years and above in eight purposively selected district that included Lira, Nebbi, Kampala, Luwero, Pallisa, Jinja, Mbarara, and Ntungamo. The study sample consisted of 101 elderly person from whom in-depth interviews were conducted. Data was analysed using qualitative thematic content analysis. Results Rural elderly in Uganda face a lot of constraints that include access to healthcare and information, poor economic status, food insecurity and poor nutrition, and poor accommodation and housing conditions. Two broader themes emerged inductively from the analysis that include care available for the rural elderly and providing care to grandchildren. These themes generated several subthemes. Taking care of grandchildren crippled the elderly and reduced the economic benefits. That said some rural elderly were happy and felt fulfilled to care of the grandchildren despite the lack of resources. Conclusion The rural elderly in Uganda are living in doleful conditions with limited care and support. They need care but are the providers of care to the grandchildren. They are frails and may not afford to provide adequate care. They care for grandchildren many of whom are orphans and vulnerable yet they themselves need care. It is important the government and the community re-enforce this care not to put strain on elderly. The rural elderly unique challenges necessitates special targeting and mobilization of resources at the household, local, district and national levels.
Gender, Creativity and Insanity: From an Anthropologist’s Notebook

Published: January 2021

This essay has emerged through my research engagements with life history as a research method in anthropology. It is based on the life events of a woman artist. The past few decades have brought an explosion of cultural criticisms and also explorations of women’s creative expressions across cultures. Some of the queries addressed are, how do external forces shape the creativity of female artists. Also, how do creative women respond to such forces? Creative women, then, have a unique relationship to their cultural contexts, as well as to the creative genre to which they respond. This essay also delves into myths related to insanity and women. It discusses creativity, as a mode of engagement with rigid social structures.

Introduction Prostate cancer is generally multifocal, presenting a lesion with a dominant focus (index lesion) that is characterized by being the lesion with the greatest volume and the biological capacity of invasion to adjacent tissues and distant metastases. With the advent of focal therapy and organ preservation in prostate cancer, it is essential to know the real tumour volume and thus, avoid the persistence of disease after treatments with curative intent. The aim of this study is to correlate the results of the dominant tumour volume obtained from the multiparametric magnetic resonance imaging (MRI) of the prostate and the histopathology. Material and Methods A retrospective study was performed which included all radical prostatectomies (RP) with previous MRI. A comparative analysis was performed between the tumour volume obtained from the MRI and the histopathology. Results A total of 46 patients were included in the study. The sensibility of the MRI in diagnosing the index lesion was 82.6%, highlighting that all tumours with a Gleason score ≥ 4+3 were diagnosed. The mean tumour volume in the MRI was 14.3 mm and in the histological result was 18.82 mm (p<0.05). The estimation tumour volume concordance was greatest in higher risk (International Society of Urological Pathology (ISUP)). Conclusion The MRI underestimates the real tumour volume of the prostate cancer index lesion when compared to the histological result of the surgical piece, being significantly lower in high-risk lesions.
The ‘way of flowers’ and the care of patients with amyotrophic lateral sclerosis in Japan
Authors: Himeno Yukiko , Inoue Osamu , Vidal Fernando
Published: January 2021

Tracheostomy with invasive ventilation (TIV) may be required for the survival of patients at advanced stages of amyotrophic lateral sclerosis (ALS). In Japan it has been shown that a proactive approach toward TIV may prolong the survival of ALS patients by over 10 years by preventing the lethal respiratory failure that generally occurs within 3-5 years of the onset of the disease. Measures to prolong life expectancy without foregoing quality of life have produced better results in Japan than in other developed countries. This ‘Japanese bias’ has been attributed to socio-cultural and religious factors as well as to the availability of material resources in Japan. In this article, we use the concepts of onozukara in kadō (Japanese traditional flower art, also called ikebana) and amae (passive love) to illuminate features of patient care that may contribute to this ‘Japanese bias’.
El Fort Farell segons Francesc Maspons
Authors: Armangué i Herrero Joan
Published: January 2021

Tant la versió de «Lo Fort Farell» de Francesc Maspons com les que la seguiren, més que no pas en llegenda consisteixen en un seguit d’anècdotes atribuïdes a l’heroi, tal com haurien pogut ser atribuïdes a qualsevol altre gegant bo. O a qualsevol home fort, veritablement fort. Recorden en efecte les aventures d’El Fuerte de Ocháran, d’Antonio de Trueba, o del popular Xic de Vaquerisses; i les gestes de Samsó, les proves d’Hèrcules, les mesures de Goliat i altres gegants de l’Antic Testament. A través del seu personal mètode historicocomparatiu, Maspons vol analitzar científicament quin lloc ocupa la nostra llegenda dins del llegendari indoeuropeu. I li sembla trobar-ne els orígens entre els pobles del Nord o germànics, tot deixant de banda el llegat romà i fins i tot bíblic. Mentre Maspons escrivia tot això, però, encara no havia estat difosa a Europa l’Epopeia de Gilgameix, heroi que es remunta al III mil·lenni aC i que no deixa de personificar… precedents llegendes.

D’Andersen a Carme Riera: una veu pròpia per a la sirena
Authors: Ferrando Simón Mireia
Published: January 2021

La veu de la sirena (2015), de Carme Riera, adopta com a text de referència —o hipotext— el conte tradicional de «La sireneta», fixat per Hans Christian Andersen (1837). Aquest estudi caracteritza la relació dialèctica que estableixen sengles obres des del punt de vista de les teoritzacions de Gérard Genette (1982) sobre la hipertextualitat. Riera reconeix obertament el text d’Andersen com a referent alhora que en canvia el sistema de valors subjacent. S’apropia del conte cla ssic per a subvertir-lo i sotmetre’l així a una alteració ideolo gica interessada. El text resultant esdevé un títol original dins de l’àmplia trajectòria de l’escriptora mallorquina i projecta, així mateix, moltes de les constants de la seua literatura.
