Structural Integration Case Report: a Global Intervention Challenging the Limitations of Local Rehabilitation
Authors: Landels, Bachelor Health Studies Bernice
Published: March 2021

Background: Conventional rehabilitation for musculoskeletal injuries postsurgery is generally site-specific and aims to return the person to ‘normal’ function. Commonly, conventional treatment focuses locally and little or no attention is given to comorbidities, other symptoms, postural compensations, or adaptations either pre-existing or resulting from the injury. Structural Integration (SI) is a manual therapy applied to and focusing on fascial continuities throughout the whole body. This case report explores SI as a global, whole-body intervention for rehabilitation. Purpose: To examine the effects of a whole-body approach that addresses local and global symptoms following ankle surgery. Methods: The Anatomy Trains Structural Integration (ATSI formerly KMI) 12-series protocol was applied and a selection of outcome measures were used to track progress and assess the eff icacy of SI. Ankle mobility and function was assessed primarily using Weight-Bearing Lunge Test and Lower Extremity Functional Scale. Local pain was reported using the McGill Pain Questionnaire. General wellbeing was evaluated using subjective questioning and the WHO Quality of Life Questionnaire. Results: Local results included increased mobility and function to affected leg, and reduced pain and swelling. Global results included an improvement in physical and psychological well-being, with the reduction of pain and dysfunction in other areas. Conclusion: This case report demonstrates global benefits of a whole-body approach when structural integration is applied during rehabilitation. More clinical research that includes SI is needed to determine if the local and global results shown in this case study can be demonstrated in additional rehabilitation populations.
Photospheric Velocity Gradients and Ejecta Masses of Hydrogen-poor Superluminous Supernovae: Proxies for Distinguishing between Fast and Slow Events
Authors: Könyves-Tóth Réka , Vinkó József
Published: March 2021

We present a study of 28 Type I superluminous supernovae (SLSNe) in the context of the ejecta mass and photospheric velocity. We combine photometry and spectroscopy to infer ejecta masses via the formalism of radiation diffusion equations. We present an improved method to determine the photospheric velocity by combining spectrum modeling and cross-correlation techniques. We find that Type I SLSNe can be divided into two groups according to their pre-maximum spectra. Members of the first group have a W-shaped absorption trough in their pre-maximum spectrum, usually identified as due to O ii. This feature is absent in the spectra of supernovae in the second group, whose spectra are similar to that of SN 2015bn. We confirm that the pre- or near-maximum photospheric velocities correlate with the velocity gradients: faster evolving SLSNe have larger photospheric velocities around maximum. We classify the studied SLSNe into the Fast or the Slow evolving group according to their estimated photospheric velocities, and find that all those objects that resemble SN 2015bn belong to the Slow evolving class, while SLSNe showing the W-like absorption are represented in both Fast and Slow evolving groups. We estimate the ejecta masses of all objects in our sample, and obtain values in the range 2.9 (±0.8)−208 (±61) M
⊙, with a mean of 43 (±12) M
⊙. We conclude that Slow evolving SLSNe tend to have higher ejecta masses compared to the Fast SLSNe. Our ejecta mass calculations suggests that SLSNe are caused by energetic explosions of very massive stars, irrespective of the powering mechanism of the light curve.

Published: March 2021

Neutron star mergers (NSMs) are promising astrophysical sites for the rapid neutron-capture (“r”) process, but can their integrated yields explain the majority of heavy-element material in the Galaxy? One method to address this question implements a forward approach that propagates NSM rates and yields along with stellar formation rates and compares those results with observed chemical abundances of r-process-rich, metal-poor stars. In this work, we take the inverse approach by utilizing r-process-element abundance ratios of metal-poor stars as input to reconstruct the properties—especially the masses—of their neutron star (NS) binary progenitors. This novel analysis provides an independent avenue for studying the population of the original NS binary systems that merged and produced the r-process material now incorporated in Galactic metal-poor halo stars. We use ratios of elements typically associated with the limited-r-process and the actinide region to those in the lanthanide region (i.e., Zr/Dy and Th/Dy) to probe the NS masses of the progenitor merger. We find that NSMs can account for all r-process material in metal-poor stars that display r-process signatures, while simultaneously reproducing the present-day distribution of double-NS systems. Notably, with our model assumptions and the studied stellar sample, we postulate that the most r-process enhanced stars (the r–II stars) on their own would require progenitor NSMs of asymmetric systems that are distinctly different from present ones in the Galaxy. We also explore variations to the model and find that the predicted degree of asymmetry is most sensitive to the electron fraction of the remnant disk wind.
Validation of HD 183579b Using Archival Radial Velocities: A Warm Neptune Orbiting a Bright Solar Analog
Authors: Palatnick Skyler , Kipping David , Yahalomi Daniel
Published: March 2021

As exoplanetary science matures into its third decade, we are increasingly offered the possibility of pre-existing, archival observations for newly detected candidates. This is particularly poignant for the TESS mission, whose survey spans bright, nearby dwarf stars in both hemispheres—precisely the types of sources targeted by previous radial velocity (RV) surveys. On this basis, we investigated whether any of the TESS Objects of Interest (TOIs) coincided with such observations, from which we find 18 single-planet candidate systems. Of these, one exhibits an RV signature that has the correct period and phase matching the transiting planetary candidates with a false-alarm probability of less than 1%. After further checks, we exploit this fact to validate HD 183579b (TOI-1055b). This planet is <4 R
⊕ and has better than 33% planetary mass measurements, thus advancing TESS’ primary objective of finding 50 such worlds. We find that this planet is among the most accessible small transiting planets for atmospheric characterization. Our work highlights that the efforts to confirm and even precisely measure the masses of new transiting planet candidates need not always depend on acquiring new observations—in some instances, these tasks can be completed with existing data.

Saddle-shaped Solar Flare Arcades
Authors: Lörinčík Juraj , Dudík Jaroslav , Aulanier Guillaume
Published: March 2021

Arcades of flare loops form as a consequence of magnetic reconnection powering solar flares and eruptions. We analyze the morphology and evolution of flare arcades that formed during five well-known eruptive flares. We show that the arcades have a common saddle-like shape. The saddles occur despite the fact that the flares were of different classes (C to X), occurred in different magnetic environments, and were observed in various projections. The saddles are related to the presence of longer, relatively higher, and inclined flare loops, consistently observed at the ends of the arcades, which we term “cantles.” Our observations indicate that cantles typically join straight portions of flare ribbons with hooked extensions of the conjugate ribbons. The origin of the cantles is investigated in stereoscopic observations of the 2011 May 9 eruptive flare carried out by the Atmospheric Imaging Assembly and Extreme Ultraviolet Imager. The mutual separation of the instruments led to ideal observational conditions allowing for simultaneous analysis of the evolving cantle and the underlying ribbon hook. Based on our analysis we suggest that the formation of one of the cantles can be explained by magnetic reconnection between the erupting structure and its overlying arcades. We propose that the morphology of flare arcades can provide information about the reconnection geometries in which the individual flare loops originate.
Taxonomic position of the two sympatric forms of Chondracanthus chamissoi (f. lessonii and f. chauvinii) (Rhodophyta, Gigartinaceae) by using two molecular markers
Authors: Rodríguez Catalina Y. , Tellier Florence , Pérez-Araneda Karla , Otaíza Ricardo D.
Published: March 2021

The red seaweed Chondracanthus chamissoi shows high morphological variability. Initially, three species were identified based on the width of the main axis of their blades. Later, all of them were included in a single species with two morphological groups. Recently, quantitative studies demonstrated the existence of two forms in C. chamissoi: f. lessonii and f. chauvinii. It was also shown that these two forms occur in sympatry, growing side by side. These forms were not associated with either a life cycle phase or the sex of the blades. This study aimed to determine whether the two forms could represent different species. We evaluated the forms' taxonomic position using COI and rbcL markers, including samples from three localities in southern Chile. All specimens shared a single rbcL haplotype, whereas the two COI haplotypes differed by four base pairs and were present in blades of both forms and life cycle phases. The two morphological types correspond to intraspecific forms. This species is of commercial importance, and its main market is aimed at human consumption with a marked preference for f. lessonii.

Making Moves: Reading Saudi Social Change through Commercial Tabletop Games
Authors: Leber Andrew
Published: March 2021

While the promotion of “entertainment” has been a touchstone of policy changes in the Kingdom of Saudi Arabia of late, most media and academic focus has been on large‑scale spectacles that reflect top‑down efforts of the Saudi state to effect economic and social change. In this article, I look to smaller‑scale cultural production – the nascent Saudi tabletop games industry – to understand how Saudi entrepreneurs evoke, adapt, or subtly contest state narratives to advance projects of self‑improvement, social reform, and above all commercial retail. Drawing on interviews with several board‑game entrepreneurs as well as several recent Saudi‑produced games, I note that these games draw on a sense of national authenticity to appeal to consumers – “Buy Saudi!” – as well as to provide an immersive gaming experience. However, the worlds constructed by these Saudi‑themed game narratives in turn suggest that pre‑existing inequalities of wealth and social influence heavily structure individuals’ chances in life, even if game developers themselves more directly echo the emphasis on self‑reliance embedded in recent state development narratives. Finally, while Saudi games entrepreneurs echo their counterparts worldwide in highlighting the low‑tech, “natural” community‑building properties of tabletop games, this narrative remains ever‑so‑slightly at odds with the futurism of state narratives that instead stress the importance of building a hi‑tech, digitally networked future for Saudi society.
Review of an EMG-Controlled Prosthetic Arm
Authors: Kumar Rishabh , Singh Aditya Kumar , Mukaherjee Sabyasachi
Published: March 2021

Amputation, especially of the upper limbs, is a condition that exists in almost all parts of the world. There are more than 110 thousand amputees in India itself. It is extremely difficult for amputees to carry out their daily activities and to deal with daily life as normal people do. The purpose of the myoelectric prosthesis is to restore the basic functions of the lost organs in the joint using neural signals produced by the muscles. Unfortunately, the use of such myosignals is complicated. In addition, once detected, it usually requires a computational force strong enough to convert it into a user-controlled signal. Its modification to the actual function of the implant is limited by a number of factors, especially those associated with the fact that each amputee has a different muscle movement. Modified artificial intelligence systems designed for pattern recognition have the potential to improve the size of implants but still fail to provide a system in which artificial arms can be controlled by brain signals.

Authors: Mosweu Olefhile , Chaterera-Zambuko Forget
Published: March 2021

The fourth industrial revolution (4IR) has ushered in several emerging and disruptive technologies. Southern Africa's records management practices have for a long time been reported to lag behind in embracing new technologies. Several studies have revealed lack of requisite skills to manage electronic records while others still lament the un-procedural management of paper records. The intention of this chapter is, therefore, to initiate a discourse that challenges information management practitioners to embrace disruptive technologies lest they themselves get disrupted. There are several emerging technologies, but this chapter focuses on blockchain technology and its possible benefits for records management. Guided by the technology acceptance model, the study established that archivists and records managers in Botswana and Zimbabwe would adopt blockchain if it is easy to use and useful for records management. The chapter ends by proposing a model for the adoption of blockchain technology for records management.

The chapter presents the evolution of potential ESG risks in the healthcare sector related to striving to provide the best care for patients. Based on the literature and selected examples, the analysis of this problem will indicate potential risks of the main factors and tools that can help manage this risk in the healthcare sector. There is a research gap in the literature; there is a lack of detailed discussion and research allowing to establish the relationship between ESG factors and finances. Particular emphasis is placed on social pillar, which in the authors' opinion is critical to the functioning of the healthcare sector, especially from the face of COVID-19. The authors proposed a map to identify potential risk and possible scenarios of action in the long term. The main assumption of the study is that the implementation of ESG potential risk management leads in the long run to sustainable development in the healthcare sector.
The Impact of the Pandemic (COVID-19) on the Change of Business Models on the Example of the Banking Industry
Authors: Sawicki Przemyslaw Jacek
Published: March 2021

Due to the fundamental digitization of social/economic life, it takes on an “on” and “offline” scale image of the world. While analyzing the impact of the ongoing pandemic on the segmentation of world markets, the disruptions in the functioning of some industries, sectors, and entire economies are becoming deeper. The spread of COVID-19 has led to the dysfunction of a known ecosystem, and the destructive force of human isolation and the lockdown of economies have significantly influenced the behavior of societies and governments. Many customer-centric companies have reactively redefined their strategies, and the financial sector, especially banks, was to play an important role in absorbing the shock by providing the necessary credit to businesses and households. Meanwhile, the same institutions have experienced capital and liquidity destabilization due to increased risk reserves created and an operating in conditions of historically low interest rates. Unexpectedly, the pandemic has become another determinant of the new quality of processes, phenomena, and business models.

Published: March 2021

Introduction:

Organizing pneumonia (OP) is an idiopathic interstitial pneumonia characterized radiologically by the patchy peripheral areas of ground-glass opacities and consolidation. It is commonly associated with a variety of conditions such as connective tissue diseases (CTD), drugs, infections, malignancy, radiation exposure, post-transplant, and other interstitial pneumonia. There are no specific clinical manifestations unless there is an underlying etiology. We present a series of such cases.

Aims and Objectives:

The aim of the study was to identify the clinical characteristics and etiological spectrum of patients manifesting radiologically with OP pattern.

Materials and Methods:

This was a retrospective analysis of clinico-radiological profile and etiological diagnosis of 23 patients, who had a radiological diagnosis of OP during the period of January 2017–September 2019.

Results:

Our patients presented with nonspecific symptoms of cough, fever, breathlessness, and occasionally with hemoptysis. The various etiologies identified were CTD (n = 4), infection (n = 2), drugs (n = 4), radiation (n = 1), chronic aspiration syndrome (n = 1), malignancy (n = 2), hypersensitivity pneumonitis (n = 1), and chronic heart failure (n = 2), and in majority (n = 7), no underlying etiology was evident and were labeled as cryptogenic organizing pneumonia.

Conclusion:

OP is an underdiagnosed entity and is associated with numerous diseases varying from pulmonary tuberculosis to malignancy. Identification of the underlying disease process is of paramount importance as it enables the treating physician to implement necessary therapeutic interventions.

Published: March 2021

Introduction:

Pulmonary neuroendocrine tumors (NETs) comprise a spectrum of tumors ranging from indolent to highly aggressive neoplasm. This study aims to study the clinicopathological and immunohistochemical features of NETs and assess the sensitivity of various IHC markers.

Materials and Methods:

All consecutive cases of pulmonary NETs diagnosed from January 2016 to June 2019 were analyzed retrospectively. The routine hematoxylin- and eosin-stained sections along with immunohistochemistry (IHC) slides were reviewed. IHC was done using a panel of markers which included synaptophysin, chromogranin, CD56, thyroid transcription factor-1 (TTF-1), p-40, napsin-A, and ki67.

Results:

Of total number of 53 patients, diagnosis was made on biopsy in 40 patients and resection specimen in 13 patients. Small cell lung carcinoma was the most common (31 cases), followed by 16 cases of typical carcinoid, 5 cases of atypical carcinoid, and 1 case of combined SCLC. Both synaptophysin and chromogranin were positive in all the cases of typical carcinoid. Synaptophysin had better sensitivity than chromogranin in atypical carcinoid and small cell carcinoma. CD56 was positive in 8 out of 9 cases done. TTF-1 was negative in all the cases of typical carcinoid. The sensitivity of TTF-1 in small cell carcinoma was 85.19%. The mean Ki67 labeling index was 1.4%, 6.6%, and 65.6% in typical, atypical carcinoid, and small cell carcinomas, respectively.

Conclusion:

Synaptophysin was more sensitive than chromogranin, especially in atypical carcinoid and small cell carcinoma. TTF-1 along with high Ki67 differentiates small cell carcinoma from carcinoid.

High Strength Corrosion Resistant Steel for Aircraft Landing Gears and Structures
Authors: Vartanov Gregory
Published: March 2021

High stressed aircraft landing gear and structural components are subjected to severe loading, corrosion and adverse environmental conditions. Materials such as high strength steels and high-strength titanium alloys are widely used for those critical components. The main criterions for choosing the materials are their strength and fatigue strength, toughness and ductility.

300M steel is widely used for high stress aircraft landing gears and structures; however, this steel is not corrosion-resistant and requires protective coatings.

Cobalt-free, quenched and tempered high strength corrosion resistant steel alloy (“HSCR steel”) provides the same strength, ductility, and toughness as the 300M steel and while it possesses corrosion resistance in salt spray test. HSCR steel has showed no rust after the standard salt spray test in accordance with ASTM B117 using a 5% NaCl concentration, natural pH, at 95°F, for 200 hours test duration.

Aircraft applications of the wrought HSCR steel include landing gear components, rotatable shafts, actuators, flap tracks, slat tracks, fasteners, and others.

Besides forging, the aircraft components can be manufactured from HSCR steel powders by:

Powder metallurgical-based hot isostatic pressing (PM HIP) to the near net shapes

(NNS) followed by finish machining/surface finishing and heat treatment

Additive manufacturing (AM) followed by surface finishing and heat treatment.

Modification of the HSCR steel is applicable for vacuum and investment casting of aircraft hydraulic fluid system, motion control and actuation system, cargo system, and flight safety components.

HSCR steel is a low cost alternative of Ti-6Al-4V alloy. The components made from Ti- 6Al-4V alloy can be substituted by the same weight components made from HSCR steel due to HSCR steel possesses slightly higher specific stiffness and specific strength (ratio of modulus elasticity and ultimate tensile strength to density) and slightly lower ductility and toughness compared to Ti-6Al-4V alloy.

Industrial production of HSCR steel is underway.

Published: March 2021

Taro leaf blight causes up to 100% yield loss in susceptible taro (Colocasia esculenta L. (Schott)) cultivars. The use of fungicides in disease management is fast and effective; however efficacy of fungicides could be affected by frequency of application. The objective of this study was to evaluate the efficacy of spraying intervals and economic benefits of Ridomil Plus 66 WP (12% Metalaxyl-M and 60% Copper (1) oxide) on taro leaf blight disease. The study consisted of four fungicide spraying intervals, viz at one, two and at four weekly intervals, all at the concentration of 3.3 g l-1 and no fungicide application as the control. Results showed no significant differences (P > 00.5) between one and two weekly spraying intervals in terms of taro leaf blight disease incidence and severity. These were, however, significantly different (P < 0.05) from four weekly and no fungicide applications. Taro corm yield was higher in weekly spraying interval, but not significantly different (P > 0.05) from biweekly application intervals. Yields in weekly intervals were 2.9, 33.0 and 44.0% higher than biweekly, four weekly and no application intervals. Applying fungicide at a biweekly interval was found to be economically efficient as it recorded higher total revenue and net present values. Applying 66 WP (12% Metalaxyl-M and 60% Copper (1) oxide) at 2 weekly interval was the optimum period and most efficient to reduce the incidence and severity of Phytophthora leaf blight disease and increase yield of taro.

It is recommended that the study be conducted in larger groups.
Sumak Kawsay y buen vivir, ¿dispositivos del desarrollo? Ética ambiental y gobierno global
Authors: Cortez David
Published: March 2021

Entre las personas dedicadas a analizar el buen vivir o sumak kawsay destaca David Cortez, autor de este libro. Pronto él avizoró que es un concepto en disputa, ya que unos impulsan el buen vivir como una alternativa al desarrollo, distante de la matriz occidental, mientras que otros encuentran en dicha noción elementos para una nueva teoría del desarrollo. Cortez también comprendió, oportunamente, el riesgo que se cernía sobre el buen vivir o sumak kawsay: ser transformado en un dispositivo de poder y una simple herramienta de propaganda, como de hecho sucedió. De eso trata esta obra. El autor traza un antes y un después desde que el buen vivir o sumak kawsay fuera incorporado a la Constitución del Ecuador, en 2008. Para demostrar la larga historia que tiene esta noción, presenta el complejo entramado de actores que han participado activamente en los debates desde la década de los años ochenta. Resulta aleccionadora la aproximación de Cortez a las diversas lecturas que se han hecho y se hacen desde las posiciones liberales-conservadoras o progresistas-conservadoras, las cuales defienden -cada una a su manera- la civilización occidental, inclusive incorporan una aproximación teológica de la interculturación e interculturalidad con enorme influencia de la Iglesia. Confluyen en ese ancho cauce la exaltación de la cultura ancestral y su esencialismo, el debate ecologista y las posiciones de los estudios postdesarrollistas y postcoloniales. En ese terreno pantanoso y de enfrentamiento de múltiples intereses, las reflexiones contenidas en este libro arrojan nuevas luces. Para organizar el debate, nada mejor que estudiar este aporte de David Cortez.

Published: March 2021

Traditionally, focus groups have been conducted in person using the face-to-face format. However, improvements in technology have resulted in the emergence of the online focus groups. Online focus groups are an extension of traditional focus groups, which have been utilized in qualitative research for decades and, for the most part, the principles are consistent with traditional focus groups. Learning to conduct online focus groups requires the researcher to delve into the literature on traditional focus groups, as having a thorough understanding of traditional focus groups is paramount. After gaining a sufficient understanding of traditional focus groups, the researcher can explore journal articles and video clips addressing the nuances of online focus groups.

Kozinets' (2010) new text explores netnography, or the conduct of ethnography over the internet - a method specifically designed to study cultures and communities online. Guidelines for the accurate and ethical conduct of ethnographic research online are set out, with detailed, step-by-step guidance to thoroughly introduce, explain, and illustrate the method to students and researchers. Kozinets surveys the latest research on online cultures and communities, focusing on the methods used to study them, with examples focusing on the blogosphere (blogging), microblogging, videocasting, podcasting, social networking sites, virtual worlds, and more. The book is essential reading for researchers and students in social sciences.
Corporate Ethnographers: Master Puzzlers, What They Do, and Their Value to the Business Sector
Authors: Obenchain-Leeson Alice
Published: March 2021

Melissa Cefkin's book Ethnography and the Corporate Encounter is the fifth volume in a six-volume series on studies in public and applied anthropology by Berghahn Publishing. Cefkin unearths the world of corporate ethnography by explaining how the field evolved from the larger field of anthropology. Through collecting a variety of corporate ethnography studies conducted at Intel, Microsoft, and others, Cefkin brings to life the work of corporate ethnographers as master puzzlers as she attempts to answer the questions: What are corporate ethnographers and under what conditions do they work? What value does ethnography bring to the understanding of complex business sector problems?
Someone Else’s Child: A Co-Constructed, Performance Autoethnography of Adoption from Three Perspectives
Authors: Danzak Robin , Gunther Christina , Cole Michelle
Published: March 2021

Through a framework of reconciling the other, this collaborative autoethnographic performance co-constructs the adoption experience from three perspectives in three different families: a mother struggling with the ethical and emotional implications of the transnational adoption of her daughter; an adult reflecting on her childhood as an adoptee feeling loved, but different; and a woman who met her biological sister at age 28 after her parents revealed a lifelong secret. To develop individual adoption narratives, we applied autoethnographic tools of interactive interviews with family members, reflective writing, and document review (Ellis, 2004) of photos, letters, emails, and calendars. During one school year, we met monthly to discuss relevant literature, share and critique each other’s methods and writing, and identify the common themes in our three, diverse experiences. The result of the iteration of the individual and group processes is a script that weaves together our adoption stories, the discoveries of ourselves, and how, after negotiating feelings and identities, we reconciled the other through positive, loving relationships.

LEGAL RESPONSIBILITY IN THE MECHANISM OF ENSURING NATIONAL SECURITY
Authors: Липинский Д.А. , Макарейко Н.В.
Published: March 2021

Аннотация. Исследование механизма обеспечения национальной безопасности позволило определить внутренние связи юридической ответственности как сложного образования, а также внешние связи с другими применяемыми правоохранительными средствами. Изменение угроз, которые обусловлены как противоправными деяниями, так и ростом числа аномалий с правовым содержанием, требуют перенастройки института юридической ответственности. В действующем законодательстве должен быть заблаговременно закреплен правоохранительный потенциал, позволяющий эффективно противодействовать существующим и потенциальным рискам в сфере национальной безопасности.

The study of the mechanism for ensuring nationality made it possible to determine the internal links of legal responsibility as a complex entity, as well as external links with other applied law enforcement means. Changes in threats that are caused by both illegal acts and an increase in the number of anomalies with legal content require reconfiguring the institution of legal responsibili-
The impact of corporate respect for human rights on the competitiveness and long-term business stability
Authors: Certanec Ana
Published: March 2021

Business enterprises operate in a constantly changing business environment. If they are to be successful in the long term they need to be constantly adapting to new situations and seeking new ways of improving their competitiveness. While the classic theories argue that businesses only have economic goals, modern ones emphasize the importance of broader social goals, such as ensuring long-term stability and protecting the interests of all stakeholders. This also involves respecting human rights but enterprises too often neglect this responsibility, seeing it as an unnecessary financial burden. In this paper the author argues that long-term respect for human rights has a positive impact on competitiveness and long-term business stability. The author first defines the basic terms before presenting the theoretical foundations for a positive correlation between corporate respect for human rights and competitiveness and long-term business stability. Finally, the author presents the results of her own empirical study.
La idea del factum como elemento mediador entre la dimensión subjetiva y la dimensión universal de la ética
Authors: Espinosa Galicia Roberto
Published: March 2021

En el presente ensayo me propongo explorar la idea expresada por Kant sobre el factum de la razón como un elemento mediador entre los aspectos subjetivos de la ética y la demanda de universalidad y objetividad expresada en la formulación del imperativo categórico. Una de las interpretaciones más recurrentes sobre la ética kantiana es la que la concibe como un discurso que privilegia el uso de la razón en su aspecto puramente cognitivo, en detrimento de otras dimensiones que, por su contingencia, afectarían la pureza de la ley moral expresada en el imperativo categórico.
Extinción feminista
Authors: Colebrook Claire , Rodríguez González Fernanda
Published: March 2021

Mientras que la raza humana se apresura hacia su extinción, principalmente como resultado del aniquilamiento de su propio medio ambiente, nosotras las feministas podríamos responder con un: “te lo dije”. El feminismo es, como cualquier otro “ismo”, quizá demasiado diverso como para poder darle una identidad fija, y a pesar de ello es claro que su identidad ha estado dada por las críticas al hombre. Incluso en sus fases más tempranas, liberales e incluyentes, la demanda feminista de incluir a las mujeres en la categoría de “hombre” o humanidad no se hizo tanto por el bien de las mujeres como por el bien de la vida en general. No se trataba de una cuestión en la que las mujeres hicieran un reclamo egoísta, sino más bien de un llamado a una mejor vida para todos en un mundo nuevo de igualdad sexual. El feminismo nunca ha sido una cuestión de intereses particulares, sino que siempre ha apelado por una justicia mucho más amplia en la que todos los humanos puedan ser incluidos.
Bioética de otro modo o cómo vivir con máquinas, humanos y otros animales

Published: March 2021

¿De qué manera puede hablar el ser humano a la sombra de la crítica poshumanista? Este ensayo surge de un momento prolongado de duda, de una confusión cognitiva y afectiva sobre la ontología y el estatus de aquello denominado “hombre”. Ahora bien, claramente la confusión no es novedosa, ha sido inherente a la investigación disciplinar dentro de las humanidades, y en particular a la investigación asociada, durante las últimas décadas, al posestructuralismo filosófico. A inicios del siglo xxi, han contribuido aún más a la incertidumbre en torno al “hombre” los in tentos de dar un giro hacia un involucramiento más serio de las humanidades con aquellas ciencias duras que tratan diferentes partes y par tículas humanas —anatomía, neurología, genética—, así como el descubrimiento de que los típicos puntos de medición del ser humano, como el lenguaje, el uso de herramientas, la cultura (o “dejar rastros”)
La polemología en Homero
Authors: Arcila Arango Mauricio
Published: March 2021

En este artículo se indaga y problematiza sobre conceptos referidos por Home- ro, que han sido traducidos como guerra, disputa, lucha o combate, y que han sido entendidos como sinónimos a lo largo de la historia occidental. Entre las nociones referidas por Homero se encuentra una gran cantidad de conceptos que refieren de manera distinta a los fenómenos asociados a la guerra, sobresa- len los de Eris, Pólemos y Máchai, traducidos como disputa, combate y lucha. La pregunta que se vuelve evidente, entonces, es: ¿Qué es lo que entiende Homero por Eris, Pólemos y Máchai?

Published: March 2021

In recent years lot e-cards are being carried around by a person, which is definitely not very convenient. Mostly, everyone wishes to carry things in a lighter and efficient manner. The digital era is vast and a fast growing system and so does the medical field have to be digitized. In this paper, "TechMedi" - an IOT(Internet Of Things) based RFID( Radio-Frequency Identification) device is proposed. Which is used to store all medical records of the patient in the cloud database (single entity) and it is accessed under 4 modes of operation. Namely 1)Emergency 2)Nonemergency 3)Pharmacy and 4)Scanning centres. For example, If a person met with an accident, the doctor can refer to the patient’s previous medical records and find the appropriate treatment using the TechMedi. If we follow the TechMedi system, the medical crime rate can be reduced, proper database management is saved in the cloud network.
