Habitus ferviente en el Polígono Espronceda de Sabadell. Cómo el culto pentecostal rearticula la etnicidad y aumenta la autonomía personal y colectiva entre los gitanos
Authors: Fernández González Miquel
Published: March 2022

Este artículo es el resultado de una investigación etnográfica de dos años entre los gitanos pentecostales del barrio de Espronceda en Sabadell. Coincidiendo con la construcción el polígono de viviendas populares Espronceda a principios de los años 60 del siglo pasado, en la zona sur del municipio, una nueva corriente religiosa derivada del pentecosalismo proveniente de Francia, se expande entre la población gitana con un éxito sin precedentes. Acabará adoptando el nombre de Iglesia de Filadelfia y, desde entonces, hasta la actualidad transformará, no solamente las formas de organización de esta población, sempiternamente perseguida, también el sentido vital personal y colectivo. Esto se llevará a cabo dando forma a lo que he conceptualizado como Habitus ferviente. Este nuevo habitus adoptado por los miembros más activos de la congregación, será producto de los intensos y emotivos cultos que, mediante unas celebraciones diarias, efervescentes, sensuales y participativas y cargadas de mensajes sobre cómo guiarse en la vida, alterarán los cuerpos e irán progresivamente modificando sus prácticas más polémicas. Esta transformación afectará, tanto a la autoimagen individual y grupal del gitano, como a su concepción vital y sus expectativas de mejora de estatus y de alcanzar posiciones laborales intelectuales y no solamente artísticas o mercantiles.
Devenir replicante: identidades mutantes en la ciencia ficción
Authors: Francescutti Pablo
Published: March 2022

Surgida para imaginar los posibles futuros de sociedades sumidas en un vertiginoso proceso de cambio, la ciencia ficción no tardó en incorporar a sus tramas la compleja cuestión de la identidad. En este artículo se muestra cómo, tomando el testigo de la literatura de horror victoriana, el género nacido de la revolución industrial y de la aceleración social actualizó en un contexto de creciente tecnificación de la vida cotidiana los temas del Doble, de la personalidad escindida y otros motivos que exponían los pliegues y fisuras del Yo burgués. Mediante figuras de la Otredad como el alienígena, el robot, el mutante o el clon, la ciencia ficción escenificó pesadillas de despersonalización, acompañó el proceso de descentramiento del sujeto cartesiano e iluminó la constitución y deconstrucción de las representaciones de los actantes sociales. Valiosos documentos de los cambios habidos en la subjetividad contemporánea, sus narraciones nos ayudan a repensar los límites de la identidad humana, personal, genérica o étnica.
Multi-access Edge Computing: Características y aplicación en entornos rurales de baja densidad de población

Published: March 2022

Con la aparición de tecnologías disruptivas como Internet de las Cosas (IoT), Industria 4.0 o Realidad Virtual (VR), entre otras, cada vez hay más servicios y dispositivos con diferentes características que se interconectan mediante redes de comunicaciones y necesitan capacidades de computación y almacenamiento con las que, en principio, no cuentan. Para superar este problema se propuso la solución de computación en la nube (cloud computing), que consiste básicamente en confiar las tareas más pesadas a un servidor central con alta potencia computacional. A primera vista este enfoque resuelve el problema, pero, como generalmente estos servidores centrales (data centers) se encuentran lejos de los dispositivos finales, aparecen nuevos problemas, especialmente con respecto al aumento de la latencia. La siguiente propuesta es el MEC (Multiaccess Edge Computing, o computación de acceso múltiple en el borde), que es similar a la computación en la nube, pero se basa en servidores más cercanos a los usuarios, esto es, «en el borde» de la red de acceso, en lugar de servidores lejanos «en la nube». Este artículo ofrece una revisión de las principales características, de MEC, haciendo énfasis en su aplicación en escenarios como muchas regiones hispano-portuguesas, con baja densidad de población, grandes distancias entre ciudades o pueblos, y con un importante porcentaje de entornos rurales.

Published: March 2022

Abstract: Spain is the EU country with the largest area of cultivated vineyards. However, it experiences a phenomenon of disaggregation and smallholdings, making it complicated for winegrowers to invest in technification. This paper describes an experiment that will be conducted in the Span- ish wine company Pago de Carraovejas. The experiment aims at optimising storage and decision-making when packaging for shipment by developing an Artificial Intelligence system. A module will be created for the improvement of the arrangement of products in the warehouse. This way, the efficiency of the warehous0e and productivity of the winery will increase.

Published: March 2022

Background and Aim: Food safety is an important aspect to be evaluated in preventing any potentially harmful side effects of food product such as yogurt. The purple sweet potato yogurt product was developed to combine the benefits of probiotic activities in yogurt and the bioactive effects of anthocyanin in purple sweet potato. This study was performed to investigate acute and sub-chronic oral toxicity of purple sweet potato yogurt (PSPY) in mice.

Materials and Methods: Acute oral toxicity was evaluated by a 14-day observation for any clinical sign of toxicity on fifteen female balb/c mice following a single dosage of PSPY (nil, 2 or 5 g/kg body weight). The sub-chronic oral toxicity study was conducted by feeding PSPY to four groups of mice with the dose of 0, 12, 20, and 40 g/kg body weight for 28 days, and another group of mice receiving 40 g/kg body weight purple sweet potato for 14 days longer to observe any delayed toxicity effect. Body weight and clinical signs of toxicity were observed daily. Liver and kidney macroscopy and relative organ weight, liver histology, liver enzyme, and hematology profile analyses were done at the end of the study.

Results: There were no signs of toxicity observed from the acute toxicity study and no abnormality in body weight, relative organ weight, and gross organ examination. In the sub-chronic toxicity study, there were no clinical signs of toxicity, no significant differences in body weight, relative liver weight, liver enzymes, hematology profile, or abnormality in gross and histological examination of the liver.

Conclusion: This study shows that oral administration of PSPY in mice up to 5 g/kg body weight did not result in acute toxicity, while the dosage up to 40 g/kg body weight did not lead to sub-chronic toxicity.

Published: March 2022

Objective: Instrumentation failure in spine tumor surgery is a common reason for revision operation. Increases in patient survival demand a better understanding of the hardware longevity. The study objective was to investigate risk factors for instrumentation failure requiring revision surgery in patients with spinal tumors.Methods: A retrospective cohort from a single tertiary care specialty hospital from January 2005 to January 2021, for patients with spinal primary or metastatic tumors who underwent surgical intervention with instrumentation. Demographic and treatment data were collected and analyzed. Kaplan-Meier analysis was performed for overall survival, and separate univariate and multivariate regression analysis was performed.Results: Three hundred fifty-one patients underwent surgical intervention for spinal tumor, of which 23 experienced instrumentation failure requiring revision surgery (6.6%). Multivariate regression analysis identified pelvic fixation (odds ratio [OR], 10.9), spinal metastasis invasiveness index (OR, 1.11), and survival of greater than 5 years (OR, 3.6) as significant risk factors for hardware failure. One- and 5-year survival rates were 57% and 8%, respectively.Conclusion: Instrumentation failure after spinal tumor surgery is a common reason for revision surgery. Our study suggests that the use of pelvic fixation, invasiveness of the surgery, and survival greater than 5 years are independent risk factors for instrumentation failure.

Authors: Champeaux-Depond Charles , Penet Nicolas , Weller Joconde , Huec Jean-Charles Le , Jecko Vincent
Published: March 2022

Objective: To describe and analysed the functional outcome (FO) after spinal meningioma (SM) surgery.Methods: We processed the système national des données de santé (SNDS) i.e. , the French national administrative medical database to retrieve appropriate cases. We analysed the International Classification of Diseases 10 codes to assess the FO. Logistic models were implemented to search for variables associated with a favourable FO i.e. , a patient being independent at home without disabling symptom.Results: A total of 2,844 patients were identified of which 79.1% were female. Median age at surgery was 66 years, interquartile range (IQR) (56–75). Ninety-five point nine percent of the SMs were removed through a posterior ± lateral approach and 0.7% need an associated stabilisation. Benign meningioma represented 92.9% and malignant 2.1%. Median follow-up was 5.5 years, IQR (2.1–8), and at data collection 9% had died. The FO was good and increased along the follow-up: 84.3% of the patients were alive and had not associated symptoms at one year, 85.9% at 2 and 86.8% at 3 years. Nonetheless, 3 years after the surgery 9.8% of the alive patients still presented at least one disabling symptom of which 2.7% motor deficit, 3.3% bladder control problem, and 2.5% gait disturbance. One point seven percent were care-provider dependent and 2.1% chair or bedfast. In the multivariable logistic regression an older age at surgery (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.29–0.47, p < 0.001), a high level of comorbidities (OR, 0.71; 95% CI, 0.66–0.75, p < 0.001), and an aggressive tumor (OR, 0.49; 95% CI, 0.33–0.73; p < 0.001) were associated with a worse FO.Conclusion: FO after meningioma surgery is favourable but, may be impaired for older patients with a high level of comorbidities and aggressive tumor.

Published: March 2022

Objective: To evaluate how multimodal intraoperative neuromonitoring (IONM) changes during spinal ependymoma (SE) resection correlate with long-term neuro-functional outcomes.Methods: A retrospective analysis of patients aged 18 years or older who underwent surgical resection for SE over a 10-year period was conducted. IONM changes were defined as sustained transcranial motor evoked potential (TcMEP) and/or somatosensory evoked potential (SSEP) signal decrease of 50% or greater from baseline. Primary endpoints were postoperative modified McCormick Neurologic Scale (MNS) scores at postoperative day (POD) < 2, 6 weeks, 1 year, and 2 years. Univariate and multivariate analyses were performed.Results: Twenty-nine patients were identified. Average age was 44.2 ± 15.4 years. Sixteen (55.2%) were male and 13 (44.8%) were female. Tumor location was 10 cervical-predominant (34.5%), 13 thoracic-predominant (44.8%), and 6 lumbar/conus-predominant (20.7%). A majority (69.0%) were World Health Organization grade 2 tumors. Twentyfour patients (82.8%) achieved gross total resection. Thirteen patients (44.8%) had a sustained documented IONM signal change and 10 (34.5%) had a TcMEP change with or without derangement in SSEP. At POD < 2, 6 weeks, 1 year, and 2 years, MNS was significantly higher for those when analyzing subgroups with either any sustained IONM or TcMEP ± SSEP signal attenuation > 50% below baseline (all p < 0.05).Conclusion: Sustained IONM derangements > 50% below baseline, particularly for TcMEP, are significantly associated with higher MNS postoperatively out to 2 years. Intraoperative and postoperative management of these patients warrant special consideration to limit neurologic morbidity.

Authors: Shaheen Nicholas J. , Falk Gary W. , Iyer Prasad G. , Souza Rhonda F. , Yadlapati Rena H. , Sauer Bryan G. , Wani Sachin
Published: March 2022

Barrett's esophagus (BE) is a common condition associated with chronic gastroesophageal reflux disease. BE is the only known precursor to esophageal adenocarcinoma, a highly lethal cancer with an increasing incidence over the last 5 decades. These revised guidelines implement Grading of Recommendations, Assessment, Development, and Evaluation methodology to propose recommendations for the definition and diagnosis of BE, screening for BE and esophageal adenocarcinoma, surveillance of patients with known BE, and the medical and endoscopic treatment of BE and its associated early neoplasia. Important changes since the previous iteration of this guideline include a broadening of acceptable screening modalities for BE to include nonendoscopic methods, liberalized intervals for surveillance of short-segment BE, and volume criteria for endoscopic therapy centers for BE. We recommend endoscopic eradication therapy for patients with BE and high-grade dysplasia and those with BE and low-grade dysplasia. We propose structured surveillance intervals for patients with dysplastic BE after successful ablation based on the baseline degree of dysplasia. We could not make recommendations regarding chemoprevention or use of biomarkers in routine practice due to insufficient data.

Public Sector Accountability to Implement Sustainable Development Goals in Sri Lanka: Influence of Traditional and Non-Traditional Donors
Authors: De Silva Keshara , Yapa Prem W Senerath , Vesty Gillian
Published: March 2022

Implementation of Sustainable development Goals (SDGs) for better environmental sustainability in developing countries in Asia has taken centre stage in response to the major environmental and social degradation created through rapid economic development in the region. Further, lack of clarity in environmental accountability of traditional economic developmental activities and internationally funded infrastructure development projects has resulted in reduced water and air quality and imperilled biodiversity. SDG related research in developing country context is limited and the impact of the funding bodies on public sector governance and accountability is scarce. This paper aims to fill this gap by addressing environmental accountability of public sector entities in internationally funded development projects in Sri Lanka, as a fast-developing country in Asia. The results indicate that environmental degradation is a continuing issue in Sri Lanka despite the efforts of traditional donor agencies monitoring and implementing environmental sustainability guidelines and SDG principles in infrastructure projects. The drastic change in the donor landscape experienced in the country with the rise of non-traditional donors and the deficiencies in public sector governance and accountability structures pose a significant threat to attainment of SDGs, including environmental sustainability in Sri Lanka.

Published: March 2022

For decades, corporate social responsibility (CSR) has been an area at the heart of business research. The aspects of CSR that researchers have been focusing on have grown exponentially. Most research efforts have dwelled on its positive effects, including good behavioural changes, promising financial performance, social investment and development, and environmental preservation and protection. On the other hand, several scholars have questioned the credibility of CSR and its link to unethical financial conduct, particularly earnings management. This review paper uses a systematic literature review to conduct bibliometric analysis, content analysis, and thematic analysis in order to identify trends and outcomes of CSR reporting and earnings management research. The literature review search is guided by PRISMA and analyses 152 Scopus-indexed articles between 2005 and 2021. As a result, this paper reveals the most influential authors and articles, leading journals and countries, and research cluster networks. This review also outlines the theoretical perspectives and future direction of CSR and earnings management research. In addition, this review paper provides critical and beneficial insights for stakeholders and researchers.
Agroecology as a grassroots approach for environmental peacebuilding: Strengthening social cohesion and resilience in post-conflict settings with community-based natural resource management

Published: March 2022

In the Colombian Andes, farming communities face complex challenges involving conflict, climate change, peacebuilding and rural reconstruction. Organized around agroecology, farmers generate associativity processes, self-managed extension work and popular education pedagogies. This strengthens the social fabric of these communities and enhances their adaptive capacities, enabling them to persist in the context of adversity.This study investigates the potential of community-based agroecology in post-war scenarios for fostering social cohesion and community resilience; considered to be two key components of peacebuilding. Based on a systematization of experiences, we analyze the work of seven farmer-led educational initiatives, so-called Agroecology Peasant Schools (Spanish:Escuelas Campesinas de Agroecología, ECAs),in three different regions of the Colombian Andes ‐ Cauca, Valle del Cauca, and Coffee Axis. Using interviews and focus groups, we integrate the perceptions of 82 stakeholders from regional agroecology networks. The results illustrate the contexts in which ECAs emerge and demonstrate how the associative processes they advance strengthen the social fabric, enhance the capacities of farmers in agroecological management and support the socio-economic recovery of rural areas. Based on our results, we maintain that, by fostering shared identities and collective capabilities of farmers, ECAs strengthen social cohesion and community resilience and thereby contribute to the building of “positive peace” from a grassroots level. By scrutinizing local initiatives, this study generates insights for guiding contextualized peacebuilding programs, based on local needs and aspirations.

Post-quantum cryptography-driven security framework for cloud computing
Authors: Ukwuoma Henry Chima , Arome Gabriel , Thompson Aderonke , Alese Boniface Kayode
Published: March 2022

Data security in the cloud has been a major issue since the inception and adoption of cloud computing. Various frameworks have been proposed, and yet data breach prevails. With encryption being the dominant method of cloud data security, the advent of quantum computing implies an urgent need to proffer a model that will provide adequate data security for both classical and quantum computing. Thus, most cryptosystems will be rendered susceptible and obsolete, though some cryptosystems will stand the test of quantum computing. The article proposes a model that comprises the application of a variant of McEliece cryptosystem, which has been tipped to replace Rivest–Shamir–Adleman (RSA) in the quantum computing era to secure access control data and the application of a variant of N-th degree truncated polynomial ring units (NTRU) cryptosystem to secure cloud user data. The simulation of the proposed McEliece algorithm showed that the algorithm has a better time complexity than the existing McEliece cryptosystem. Furthermore, the novel tweaking of parameters S and P further improves the security of the proposed algorithms. More so, the simulation of the proposed NTRU algorithm revealed that the existing NTRU cryptosystem had a superior time complexity when juxtaposed with the proposed NTRU cryptosystem.
Curve number estimation using rainfall and runoff data from five catchments in Sudan
Authors: Ibrahim Salma , Brasi Babikir , Yu Qingchun , Siddig Magdi
Published: March 2022

The United States Natural Resources Conservation Services Curve Number (NRCS-CN) method uses the CN and rainfall to calculate runoff. However, there are still some uncertainties in the method, such as choosing the most appropriate CN value. Therefore, this study attempts to evaluate the effectiveness of using the NRCS-CN method to estimate the runoff of five catchments in Sudan. For each catchment, CN values were obtained from the number of observed rainfall-runoff events using the NRCS table, arithmetic mean, median, and geometric mean methods. For each method, Nash–Sutcliffe efficiency (NSE) was obtained to evaluate the fit between the observed and runoff, and negative NSE values were found for all methods. Negative values of NSE indicate that the observed runoff and estimated runoff are not well fitted, and the NRCS-CN method is not suitable for runoff calculation in the study areas.
Structural basis of Alzheimer β-amyloid peptide recognition by engineered lipocalin proteins with aggregation-blocking activity
Authors: Eichinger Andreas , Rauth Sabine , Hinz Dominik , Feuerbach Anna , Skerra Arne
Published: March 2022

We describe the structural analysis of two Anticalin® proteins that tightly bind Aβ
40, a peptide involved in the pathophysiology of Alzheimer’s disease. These anticalins, US7 and H1GA, were engineered on the basis of the human lipocalin 2, thus yielding compact single-domain binding proteins as an alternative to antibodies. Albeit selected under different conditions and mutually deviating in 13 amino acid positions within the binding pocket (of 17 mutated residues in total), both crystallised anticalins recognize the same epitope in the middle of the β-amyloid peptide. In the two complexes with the Aβ
40 peptide, its central part comprising residues LysP16 to LysP28 shows well defined electron density whereas the flanking regions appear structurally disordered. The compact zigzag-bend conformation which is seen in both structures may indicate a role during conversion of the soluble monomeric form into pathogenic Aβ state(s) and, thus, explain the aggregation-inhibiting effect of the anticalins. In contrast to solanezumab, which targets the same Aβ region in a different conformation, the anticalin H1GA does not show cross-reactivity with sequence-related human plasma proteins. Consequently, anticalins offer promising reagents to prevent oligomerization of Aβ peptides to neurotoxic species in vivo and their small size may enable new routes for brain delivery.
Dyslexia and Accessibility Guidelines – How to Avoid Barriers to Access in Public Services
Authors: Kennecke Ann-Kathrin , Wessel Daniel , Heine Moreen
Published: March 2022

Interaction becomes increasingly digital, including interactions with public authorities, requiring websites to be accessible for all. The strong focus on written words in digital interactions allows for assistive technology to improve access for many users. However, it might impede usability for users with reading and writing difficulties.

The present paper examines whether guidelines such as the Web Content Accessibility Guidelines (WCAG) sufficiently cover users with dyslexia and how usability can be improved for this user group. This paper expands a previously published version at the Mensch und Computer 2021 conference [1].

Using literature research and interviews with users with dyslexia and focusing on an application of the WCAG on the country level (a German law regulating accessibility for e-government websites), we confirmed and identified gaps in the WCAG for this group. We focus on within-site search, as this function is frequently used to find relevant information, esp. on infrequently visited sites such as e-government websites.

Modifications to improve search were developed based on literature and the results of the interviews. They were empirically evaluated in an online study with 31 users with dyslexia and 71 without. Results indicate that an auto-complete function, a search that compensates for spelling errors, an indicator that the search was corrected, search term summary information, and avoidance of capital letters were useful for both groups, while wider line spacing should only be used in end-user customization.
Adaptive power management algorithm for multi-source DC microgrid system
Authors: Korada Durga Malleswara Rao , Mishra Mahesh Kumar
Published: March 2022

In this work, an adaptive power management algorithm is developed for a multi-source dc microgrid system. The proposed algorithm is tested with a dc microgrid system consisting of PV, wind, batteries, supercapacitors, and variable load. The PV and wind energy systems are operated in maximum power point tracking mode to extract maximum energy from the available wind power and solar irradiation. The proposed algorithm has considered wide variation in weather conditions like zero wind velocity, zero solar irradiation, wind gust, and dynamic load change at the dc bus. For these cases, the proposed algorithm maintains the dc bus voltage constant without using a communication link. The efficacy of the proposed algorithm is tested using MATLAB-Simulink. Also, the feasibility and effectiveness of the proposed algorithm are validated using OPAL-RT control platform-based experimental studies.
Studies on deformation analysis of TLS point clouds using B-splines – A control point based approach (Part I)
Authors: Aichinger Julia , Schwieger Volker
Published: March 2022

This paper presents a method to overlay laser scan data from at least two different epochs using B-splines. Here, an approach is described in which the laser scan points are directly taken as control points for the B-spline curves or surfaces. In combination with a second part of the publication, the presented technique should be able to detect small deformations compared to the object size based on the curvature parameter. However, the method does not aim at detecting object movements, rotations or translations. Before the epoch-wise laser scan acquisition of an object, a sampling rate adjustment according to the object properties has to be performed. By means of a defining algorithm, control polygons with different numbers of points are defined from the point clouds, whose points are available in scanning order, however not in a uniform grid structure, but an irregular distributed form. As a basis for a bidirectional grid structure of tensor product B-spline surfaces a knot insertion algorithm (Boehm’s algorithm) is to be applied. While the previous process steps are implemented for both B-spline curves and surfaces, the following process steps are only available for B-spline curves so far. In a correlation analysis where the ranks of the curvatures of the B-spline curve points are used, one shift position of the curve can be generated in both epochs. This forms the foundation for the determination of identical curve points, which are iteratively improved to provide the basis for a Helmert transformation to epoch 0. The rotation and translation parameters calculated with the Helmert transformation are only used to map the B-spline curve of an epoch n to epoch 0. A determination of an object rotation is not possible, because the laser scans are not georeferenced. The transformation applied allows the representation of coordinate differences between the laser scan data of different epochs. An implementation of the process steps is available for B-spline curves so far and has to be completed for B-spline surfaces. The finalization of the implementation for B-spline surfaces will be done in a second part of the publication. The calculation process of the standard deviations of the laser scan data up to the standard deviations of the curve and surface points for detecting deformations by means of a significance test will also be listed in more detail in the second part of the publication.

An Overview of Local Floodplain Administrators and Training Needs in FEMA Region 6
Authors: Siebeneck Laura , Zavar Elyse , Manandhar Rejina
Published: March 2022

The management of flood risk poses significant challenges for communities across the United States. At the forefront of managing flood risk in the U.S. are local floodplain administrators (FPAs). Despite the importance of their role in addressing flood hazards at the local level, little is known about those who serve in this capacity. Using survey data gathered from local floodplain administrators in Arkansas, Louisiana, New Mexico, Oklahoma, and Texas, this study provides an overview of floodplain administrators in Federal Emergency Management Agency (FEMA) Region 6. Specifically, this research examines perceived strengths and challenges of floodplain administrators in their ability to carry out their roles and responsibilities, and explores how perceived strengths and challenges in ability vary based on location, experience, and previous floodplain management training. This study provides new insights into the strengths and challenges individuals experience in this role and analyses suggest that significant differences exist in the perceived abilities of floodplain managers based on whether they work in an urban and rural setting, their years of experience, and previous training. Based on the findings, this study offers recommendations about training needs and strategies that would benefit current floodplain administrators as they enhance resilience to floods in their communities.
Thermal Shear Waves Induced in Mesoscopic Liquids at Low Frequency Mechanical Deformation
Authors: Kume Eni , Noirez Laurence
Published: March 2022

We show that a confined viscous liquid emits a dynamic thermal response upon applying a low frequency (∼1 Hz) shear excitation. Hot and cold thermal waves are observed in situ at atmospheric pressure and room temperature, in a viscous liquid (polypropylene glycol) at various thicknesses ranging from 100 µm up to 340 µm, upon applying a mechanical oscillatory shear strain. The observed thermal effects, synchronous with the mechanical excitation, are inconsistent with a viscous behaviour. It indicates that mesoscopic liquids are able to (partly) convert mechanical shear energy in non-equilibrium thermodynamic states. This effect called thermo-elasticity is well known in solid materials. The observation of a thermal coupling to the mechanical shear deformation reinforces the assumption of elastically correlated liquid molecules. The amplitude of the thermo-elastic waves increases linearly by increasing the shear strain amplitude up to a transition to a non-linear thermal behavior, similar to a transition from an elastic to plastic regime. The thermo-elastic effects do not give rise to any change in stress measurements and thus the dynamic thermal analysis provides unique information about dynamic liquid properties.
Status, abundance, and food habit of Sambar deer (Rusa unicolor) in tropical deciduous forest of Central India
Authors: Haleem Abdul , Ilyas Orus
Published: March 2022

Variation in the foraging strategies of Sambar deer (Rusa unicolor) with changing plant availability has received little attention. The pellet group density and seasonal vegetation availability in tropical climatic conditions of dry deciduous forest of Pench Tiger Reserve, were assessed through indirect evidences (pellet group density). Stratified random sampling was used in different habitats from 2012 to 2015 on a seasonal basis. The Sambar deer (R. unicolor) is one of the largest deer species distributed throughout the Indian subcontinent. Pellet group data were collected on 10 m radius permanent plots at every 200 m intervals on line transects. Teak forest, teak mixed and bamboo forest was the preferred habitat during summer (89.87 ± 88.36), and winter (98.19 ± 94.59) seasons respectively. Microhistological study was conducted to understand the feeding preferences of Sambar through pellet groups. A total of 57 plant species were identified in summer diet. While 51 species of plants were identified in winter diet. Sambar is predominantly a browser and for the conservation of the declining population of Sambar, long undisturbed tract should be protected with preferred browse and grass species.
Integral prefilters and integral Eq-algebras
Authors: Paad Akbar
Published: March 2022

In this paper, the notion of some new classes of EQ-algebras which are called integral, O-local, and locally finite EQ-algebras are introduced, and relationships between locally finite EQ-algebras and maximal prefilters are described. Also, the notion of integral prefilters are introduced and several characteristics of them are presented. Moreover, relation among integral prefilters and some type of other prefilter such as positive implicative, maximal, prime, and fantastic prefilters in EQ-algebras are studied. Finally, Boolean prefilters in bounded lattice EQ-algebras are introduced, and it is proved that a filter of a prelinear involutive EQ-algebra L is a Boolean filter if and only if L/F is a Boolean algebra.
Nietzsche und die Medizin
Authors: Heinrich Johannes
Published: March 2022

Nietzsche and Medicine. Especially in times of a pandemic, dealing with terms such as health, illness, healing and medicine is of particular interest. Three recently published books are devoted to the problem of medicine in Nietzsche’s work. In addition to impulses for contemporary medical-ethical debates, this review articles discusses Nietzsche’s relationship to the ancient philosophy of medical self-care, the concepts of suffering, illness and health as well as the influence of the contemporary natural sciences on Nietzsche’s understanding of medicine. Nietzsche’s view of medicine has already been the subject of several other recent publications: in addition to the publications that deal directly with Nietzsche’s understanding of medicine, I will also discuss those focused on the effect of Nietzsche’s scientific reading on his work as well as publications on the topics of illness and health and on the role of ancient dietetics, therapeutics and self-care within Nietzsche’s thinking.

Published: March 2022

In recent years, PVDF(polyvinylidene fluoride) and its copolymers have attracted great attention in the development of energy-harvesting devices because of their unique properties such as good flexibility, environmental friendliness, high halogen and acid resistance, lightweight and good biocompatibility. Compared to the most commonly used PZT (lead zirconate titanate), the piezoelectricity of PVDF and its copolymer-based materials is relatively low. To further expand the applications of PVDF, there is an urgent need for efficient methods to prepare high piezoelectric polymers or composites. In this work, the crystal phases are introduced first. Then, the preparation methods of PVDF and its copolymer-based materials are summarized, which are mainly focused on four determining factors of piezoelectricity. The mechanisms of piezoelectric β-phase formation and α- to β-phase transformation are introduced. The influence parameters of each process and their interactions are discussed in detail. In the last section, the progress of the preparation methods is summarized. This work will provide useful information to researchers working on piezoelectric composites.
Flexible silicone rubber/carbon fiber/nano-diamond composites with enhanced thermal conductivity via reducing the interface thermal resistance

Published: March 2022

Insulating materials with heat dissipation are urgently required for modern electronic devices and systems. In this study, 4,4-methylene diphenyl diisocyanate was used as the coupling agent, and nano-diamond (ND) particles were grafted onto the surface of carbon fibers (CFs) to prepare CF-ND/silicone rubber (SR) composites. The ND acted as a “bridge” among CFs, which can reduce the interface thermal resistance between CFs because the dot-like ND can increase the interfacial area of CFs, making it easier to form heat-conducting networks between SR. When the content of CF-ND (1:6) was 20%, the thermal conductivity of the SR composite was 0.305 W/(m·K), 69% higher than that of pure SR. The ND between CFs can improve the dynamic mechanical properties by acting as a crack pinhole. In addition, the CF-ND/SR composites also exhibited excellent thermal stability. This work has enormous potential for advanced electronic devices.
Saying “no” in emails in Mandarin Chinese and Australian English
Authors: Li Wei
Published: March 2022

The present study examined the differences between Mandarin Chinese and Australian English in email refusals. An email production questionnaire (EPQ) and retrospective verbal reports (RVR) were used to collect data. Results showed that while both groups preferred directness to indirectness at the utterance level, Chinese participants used indirectness significantly more frequently than Australian participants in refusals of requests. In addition, Chinese refusals were more indirect than Australian refusals at the discourse level. Chinese participants chose significantly more supportive moves than Australian participants and tended to put multiple supportive moves before the direct head act in refusals of either invitations or requests. The two groups also differed considerably in the content of refusal strategies. Moreover, both the EPQ and RVR data showed that Chinese were more sensitive to social status than Australians. The findings of this study were broadly consistent with studies on refusals in oral communication despite some differences.

„Partizipation – ein Schlüsselkonzept für Public Health?“
Authors: Hartung Susanne , Wihofszky Petra
Published: March 2022

Partizipation ist in der nationalen Public Health-Strategie verankert. Deren Eckpunkte zeigen Partizipation als Schlüsselkonzept. Die Forderung nach Partizipation, definiert als Teilhabe von Menschen an gesundheitsrelevanten Entscheidungen, ist in der Prävention und Gesundheitsförderung breit etabliert. Für die Umsetzung bietet die Partizipative Gesundheitsforschung (PGF) geeignete Ansatzpunkte und verweist darauf, Partizipation als ein ethisches Prinzip von Public Health zu verstehen.
Menschenrechte als ethische Grundlage der Gesundheitsprofessionen – Eine Skizze zu den Disziplinen und ihren Handlungsfeldern
Authors: Frewer Andreas , Sonnauer Franziska , Emmer De Albuquerque Green Caroline
Published: March 2022

Ausgehend von Definitionen der Disziplinen Menschenrechte und Ethik verbindet der Artikel normative und rechtliche Bedeutung der Menschenrechte. Dies wird ausgeführt am Menschenrecht auf Gesundheit mit staatlichem und individuellem Handeln im Gesundheitswesen. Menschenrechte als ethische Grundlage auf Public Health anzuwenden, bedeutet abzuwägen zwischen Rechten und Pflichten für Individuum und Kollektiv, wie exemplarisch an aktuellen Kontroversen der Corona-Pandemie veranschaulicht wird.
Warum brauchen wir Ethik in Public Health?
Authors: Schröder-Bäck Peter
Published: March 2022

Public Health als wissenschaftliche Multidisziplin („Gesundheitswissenschaften“) und Institution orientiert sich an Werten. Werte sind das, was Menschen anstreben und als moralisch gut ansehen, beispielsweise „Gesundheit“ und „Öffentlichkeit“. Werte liegen moralischen Urteilen zugrunde. Muss man moralische Urteile begründen und Handeln rechtfertigen? Dieser Artikel plädiert für eine positive Antwort. Institutionelles und professionelles Handeln in Public Health braucht ethische Reflexion.
Das gesellschaftliche Ansehen von Berufen – Konstruktion einer neuen beruflichen Ansehensskala und empirische Befunde für Deutschland
Authors: Ebner Christian , Rohrbach-Schmidt Daniela
Published: March 2022

Ein hohes Ansehen verschafft Individuen Macht und Einfluss in der Gesellschaft. Da Ansehen nachweislich auch sozialen Positionen, wie etwa Berufen, zugeschrieben wird, ist es als symbolische Ressource systematisch in der Sozialstruktur von Ländern verankert. In diesem Beitrag beschreiben wir eine aktuelle Erhebung des Ansehens von Berufen in Deutschland (Jahr 2017/18) und stellen der Sozialforschung eine neue berufsbasierte Ansehensskala (BAS) zur Verfügung. Auf der Grundlage von 9.011 realisierten Interviews und 45.050 Berufsprestigebewertungen werden Ansehenswerte für insgesamt 402 Berufe bestimmt. Aufbauend auf den Prestigebewertungen dieser Berufe erstellen wir auf der Ebene von Berufsgruppen und Berufshauptgruppen berufliche Ansehensskalen für die aktuelle Klassifikation der Berufe 2010. Erste Tests deuten auf eine hohe Reliabilität und Validität der Skalen hin. Der Beitrag schließt mit Überlegungen zum Einsatz und Nutzen der Skalen für die Wissenschaft.
