Abstract. With the advent of faster magic-angle spinning (MAS) and higher magnetic fields, the resolution of biomolecular solid-state nuclear magnetic resonance (NMR) spectra has been continuously increasing. As a direct consequence, the always narrower spectral lines, especially in proton-detected spectroscopy, are also becoming more sensitive to temporal instabilities of the magnetic field in the sample volume. Field drifts in the order of tenths of ppm occur after probe insertion or temperature change, during cryogen refill, or are intrinsic to the superconducting high-field magnets, particularly in the months after charging. As an alternative to a field‒frequency lock based on deuterium solvent resonance rarely available for solid-state NMR, we present a strategy to compensate non-linear field drifts using simultaneous acquisition of a frequency reference (SAFR). It is based on the acquisition of an auxiliary 1D spectrum in each scan of the experiment. Typically, a small-flip-angle pulse is added at the beginning of the pulse sequence. Based on the frequency of the maximum of the solvent signal, the field evolu-tion in time is reconstructed and used to correct the raw data after acquisition, thereby acting in its principle as a digital lock system. The general applicability of our approach is demonstrated on 2D and 3D protein spectra during various situations with a non-linear field drift. SAFR with small-flip-angle pulses causes no significant loss in sensitivity or increase in exper-imental time in protein spectroscopy. The correction leads to the possibility of recording high-quality spectra in a typical biomolecular experiment even during non-linear field changes in the order of 0.1 ppm h−1 without the need for hardware solu-tions, such as stabilizing the temperature of the magnet bore. The improvement of linewidths and peak shapes turns out to be especially important for 1H-detected spectra under fast MAS, but the method is suitable for the detection of carbon or other nuclei as well.
A pilot study of the effects of faculty status for medical librarians in the United States
Authors: Laws Sa'ad
Published: November 2021

Objectives: Within many institutions, there are debates over whether medical librarians should be classified as faculty or professional staff, a distinction that may have considerable effect on the perception of librarians within their local institutions. This study is a pilot exploration of how faculty status may affect the professional experiences of academic medical librarians within their local institutions. Methods: Surveys were sent to 209 medical librarians listed as having some instructional function at Liaison Committee on Medical Education (LCME) accredited medical institutions in the United States. Survey responses were captured using Qualtrics survey tool and analyzed for frequencies and associations using SPSS version 27. Results: Sixty-four medical librarians at academic medical institutions completed the survey developed for this study. Of the respondents, 60.9% indicated that librarians at their institution have faculty status, while 71.9% believe that librarians at their institution should have faculty status. Ninety percent of librarians with faculty status reported that they are expected to generate scholarly materials, compared to 28% of those without faculty status. Conclusions: Many medical libraries offer faculty status to librarians. While many medical librarians are active in instruction, research, and other activities normally associated with faculty status, it is not clear if faculty status impacts how librarians are perceived by other health care workers within their institutions.
Development of an efficient search filter to retrieve systematic reviews from PubMed
Authors: Salvador-Oliván José Antonio , Marco-Cuenca Gonzalo , Arquero-Avilés Rosario
Published: November 2021

Objective: Locating systematic reviews is essential for clinicians and researchers when creating or updating reviews and for decision-making in health care. This study aimed to develop a search filter for retrieving systematic reviews that improves upon the performance of the PubMed systematic review search filter.Methods: Search terms were identified from abstracts of reviews published in Cochrane Database of Systematic Reviews and the titles of articles indexed as systematic reviews in PubMed. Both the precision of the candidate terms and the number of systematic reviews retrieved from PubMed were evaluated after excluding the subset of articles retrieved by the PubMed systematic review filter. Terms that achieved a precision greater than 70% and relevant publication types indexed with MeSH terms were included in the filter search strategy.Results: The search strategy used in our filter added specific terms not included in PubMed’s systematic review filter and achieved a 61.3% increase in the number of retrieved articles that are potential systematic reviews. Moreover, it achieved an average precision that is likely greater than 80%.Conclusions: The developed search filter will enable users to identify more systematic reviews from PubMed than the PubMed systematic review filter with high precision.
Para mayor satisfacción (de): expresión conectiva plurifuncional, fundamentación y disuasión
Authors: Cucatto Mariana
Published: November 2021

A través de la expresión para mayor satisfacción (de), los jueces anuncian en sus sentencias que procederán a abundar en argumentos no dirimentes para responder más y mejor a las pretensiones y defensas de las partes. En esta oportunidad estudiamos, a partir del análisis de sentencias emitidas por la Suprema Corte de Justicia de Buenos Aires (Argentina), en qué consiste el poder persuasivo de estas razones introducidas para mayor satisfacción (de). Al respecto, mostramos que para mayor satisfacción (de) es un dispositivo conectivo que permite establecer: 1) vínculos interpretativos complejos –e icónicos–, dado que posee una triple función conectiva: contraste + adición + cierre; 2) diferentes “grados de destinación”, ya que entabla un tipo de destinación gradual, orientada a disuadir directamente al recurrente, para que cambie su manera de pensar o de actuar, e indirectamente al recurrido y, más remotamente, a otros destinatarios, a fin de prevenir sobre los efectos negativos de no seguir la postura asumida por esta Corte.
Usos del lenguaje en tareas científico-académicas: el caso de los vicios de estilo
Authors: Martínez Ezquerro Aurora
Published: November 2021

En el contexto universitario se considera implícitamente que los estudiantes han sido alfabetizados y disponen de las adecuadas estrategias lecto-escritoras. En el desarrollo de sus prácticas discursivas, deberían dominar las destrezas propias del ámbito, pero numerosos estudios confirman que dichas habilidades no se han alcanzado y los textos científico-académicos producidos acusan notables carencias estructurales y comunicativas (Tusón 1991; Carlino 2013; Camps y Castelló 2013). A la luz de esta premisa, la presente investigación empírica basada en un estudio de caso realizado con estudiantes del Grado en Educación Primaria (Universidad de La Rioja) analiza ―mediante una exploración de carácter cualitativo y descriptivo― los usos estilísticos del lenguaje en tareas asignadas en la asignatura “Didáctica de la Lengua Castellana y su Literatura”. El corpus recogido a partir de las muestras discursivas científico-académicas ofrece profusión de vicios estilísticos que denotan falta de adecuación a la situación comunicativa, ausencia de planificación y deficiente conocimiento de la normativa lingüística, entre otras particularidades. El extenso análisis realizado ha permitido valorar qué modelos o experiencias lingüístico-discursivas poseen los estudiantes, cuáles son las características de su producción en contextos formales, qué causas explican la ausencia de dominio de las destrezas lingüísticas y cuáles serían las soluciones para mejorar en las tareas del ámbito científico-académico
"Are You There, Trademark Law? It's Me, Misogyny."
Authors: Bartow Ann
Published: November 2021

When I became aware of the emergent body of legal scholarship on menstruation related topics on which this Symposium builds, I thought that the authors of these articles were very brave.1 I’m an imperfect but life-long feminist and accepted the emotional challenge that writing this Essay posed for me out of gratitude to those authors. Because my principal scholarly focus is intellectual property law, I approached the topic through the lens of trademark law. Part One of this article positions this Essay firmly within the contours of the author’s life and personal experiences with menstruation. Part Two maps common trademark and branding practices related to tampons and sanitary napkins. Part Three explains that the Lanham Act does not offer legal mechanisms by which to challenge the federal registration of sexist trademarks. As with racist trademarks, amplified criticism and persistent public pressure are the main mechanisms available to foment positive change in the marketplace for feminine hygiene products.
Law's Ability to Further the "Menstrual Movement"
Authors: Cotropia Christopher A.
Published: November 2021

The current menstrual movement calls for overcoming the cultural stigma associated with menstruation, achieving “menstrual equity,” and ending “period poverty.” The stigma the movement seeks to address is that menstruation is seen as taboo, unclean, and impure. The movement’s aims are twofold: First, it wants to increase awareness of menstruation and remove discrimination against those who menstruate, thus achieving menstrual equity. Second, it intends to provide greater access to menstrual hygiene products (“MHPs”), particularly for homeless and lower income people, thus eliminating period poverty. To achieve these goals, the movement is advocating to legislatively eliminate the “tampon tax” and increase access to MHPs in prisons, homeless shelters, and schools. It also supports lawsuits challenging the constitutionality of the tampon tax. Advocates view these legal changes as instrumental in furthering the goals of equity and access to MHPs that underlie the movement. This Essay discusses whether the two major legislative changes the movement advocates—repeal of the tampon tax and providing MHPs in schools for free—will actually achieve the movement’s goals. The Essay begins by explaining how these legal changes, in theory, are meant to address menstrual equity and period poverty. It then explores the operational limits to, and expressive benefits of, these legal proposals. The Essay concludes that the expressive function of demanding these legal changes, and sometimes achieving them, plays a more significant role than the laws’ actual operation in reaching the movement’s goals.
Menstruation Discrimination and the Problem of Shadow Precedents
Authors: Widiss Deborah A.
Published: November 2021

The burgeoning menstrual justice movement highlights that women, girls, transgender men and boys, and non-binary persons may face discrimination or harassment due to their menstruation in workplaces, schools, prisons, and many other aspects of life. In recent years, a few courts have suggested such discrimination may violate Title VII, the federal law that prohibits sex discrimination in employment. Their analysis focuses on the Pregnancy Discrimination Act (PDA), an amendment to Title VII passed in response to a Supreme Court case holding that pregnancy discrimination was not sex discrimination. The PDA overrode the decision by explicitly defining sex as including “pregnancy, childbirth, or related medical conditions.”

The menstruation discrimination cases thus implicate more general questions of how statutory overrides should be interpreted, a subject I’ve explored extensively in prior work. My research suggests that this nascent litigation campaign may face two distinct challenges. The first is that courts will simply deny the claims, reasoning that menstruation is not directly addressed by the text of the PDA and therefore should not be recognized as sex discrimination. The second—which is more subtle, and also perhaps more likely—is that courts could find such discrimination to be actionable, but do so relying solely on the PDA’s explicit reference to “medical conditions” related to pregnancy. While that would be helpful for addressing discrimination in workplaces, it could open the door to arguments that menstruation is outside the ambit of sex discrimination laws that were not amended in a manner analogous to how Title VII was amended.

To avoid these potential risks, theorists and advocates should seek to establish that menstruation discrimination is discrimination on the basis of “sex” itself, in that it is a condition linked to female reproductive organs and associated with stereotypes about women’s inferiority. That reasoning, which suggests that the PDA is properly interpreted as signaling Congress’s disapproval with the Supreme Court’s unduly narrow understanding of what constitutes sex discrimination in the earlier pregnancy case, should apply not only to Title VII, but also to the interpretation of statutory and regulatory prohibitions on sex discrimination in non-employment contexts.
How Racial Politics Led Directly to the Enactment of the Adoption and Safe Families Act of 1997
Authors: Guggenheim Martin
Published: November 2021

This Article is part of a celebration of the magnificent work of Dorothy Roberts who, more than any other scholar, has brilliantly demonstrated both the highly destructive qualities of the United States’ family regulation system and its relationship to the country’s legacy of slavery. The most vicious feature of the current family regulation system is the almost routine destruction of families resulting from an overly zealous enforcement of the Adoption and Safe Families Act of 1997, through which the federal government pays states to permanently banish parents from their children and legally sever the parent-child relationship when children have remained in foster care for fifteen months. This Article tells some of the racialized history that led to the enactment of the Adoption and Safe Families Act.
Assimilation, Removal, Discipline, and Confinement
Authors: Rolnick Addie C.
Published: November 2021

A full understanding of the roots of child separation must begin with Native children. This Article demonstrates how modern child welfare, delinquency, and education systems are rooted in the social control of indigenous children. It examines the experiences of Native girls in federal and state systems from the late 1800s to the mid1900s to show that, despite their ostensibly benevolent and separate purposes, these institutions were indistinguishable and interchangeable. They were simply differently styled mechanisms of forced assimilation, removal, discipline, and confinement. As the repeating nature of government intervention into the lives of Native children makes clear, renaming a system does not change its effect. The historical roots of these systems must be acknowledged, and the current systems must be abolished and replaced. To answer the question of what a nonpunitive, non-assimilative system would look like, this Article looks to tribal courts and indigenous justice systems. It points to specific examples of how Native communities have reshaped ideas about caring for and disciplining children, including traditional adoption, kinship care, wellness courts, family group conferencing, and a “best interests” standard that emphasizes the link between individual and collective well-being.

U.S. history is rooted in the rationalization of family separation to benefit white supremacy, capitalism and mainstream U.S. values. Because of this dark history, the U.S. history has become the world’s leader of legal destruction of families through termination of parental rights. It is the only country in the world that routinely pays people to adopt children whose parents, often women, very much want to be their parent. The Adoption and Safe Families Act, enacted in 1997, wildly changed the legal landscape of the family regulation system. At that time 47% of the children in the system were Black, and the drug war had been targeting Black men for low level offenses, and labeling Black mothers as “crack moms”. The result was an extreme attack on Black families, for which we have yet to recover.  
Abolition teaches us to unroot oppressive structures, disrupt and dismantle them while simultaneously supporting a praxis of imagination, healing, and building. In this paper, we encourage people not only to work to repeal ASFA, but to interrogate the imagination which entrenched the legitimacy of ASFA. Part I centers the discussion in our imaginations—the world we want to build, and the demands we are making. Part II moves into a discussion about the counter imagination, the ideas and mythology that created ASFA—the legal framework. In this section, we isolate ASFA as a target for abolition and organizing. Part III moves into a practical discussion about ethical ways to mobilize around ASFA. This section is intended to invite the reader to learn, and question, together. It invites questions, thinking, and problem solving in lieu of providing a recommendation.
Elliott Carter's Analysis of his Piano Sonata (1945-46)
Authors: Braus Ira
Published: November 2021

In 1948, Elliott Carter penned an analysis of his Piano Sonata for Edgard Varèse.  His analysis of the first movement, in particular, makes one ask why Carter did not subsume its recurrent two-tempo structure under “first group” of its sonata form.  Given Carter’s sophistication,  was he experiencing a moment of music historical “agnosia,” since two-tempo expositions inform  familiar Beethoven  works such as  Piano Sonata, op.31, no.2 and String Quartet in Bb, op.130. This paper explores Carter’s “agnosia” by way of internal and external evidence. Internally, it revisits the thematic chart he attached to the 1948 analysis and goes on to posit the idea that the work’s quintal neo-tonality so saturates its thematic network themes as to distort the composer’s analysis of the form, historical precedents irrespective.  Externally, the paper  compares three works by Beethoven to Carter’s Sonata as regards its two-tempo structure, using concepts borrowed from Hepokoski and Darcy’s Elements of Sonata Theory (1999).  Finally, the author revisits  writings of Carter and his circle that may explain why his analysis downplayed historical precedents to the Piano Sonata.
Calculated Discrimination: Exposing Racial Gerrymandering Using Computational Methods
Authors: Menter Aviel
Published: November 2021

In Rucho v. Common Cause, the Supreme Court held that challenges to partisan gerrymanders presented a nonjusticiable political question. This decision threatened to discard decades of work by political scientists and other experts, who had developed a myriad of techniques designed to help the courts objectively and unambiguously identify excessively partisan district maps. Simulated redistricting promised to be one of the most effective of these techniques. Simulated redistricting algorithms are computer programs capable of generating thousands of election-district maps, each of which conforms to a set of permissible criteria determined by the relevant state legislature. By measuring the partisan lean of both the automatically generated maps and the map put forth by the state legislature, a court could determine how much of this partisan bias was attributable to the deliberate actions of the legislature, rather than the natural distribution of the state’s population.Rucho ended partisan gerrymandering challenges brought under the U.S. Constitution—but it need not close the book on simulated redistricting. Although originally developed to combat partisan gerrymanders, simulated redistricting algorithms can be repurposed to help courts identify intentional racial gerrymanders. Instead of measuring the partisan bias of automatically generated maps, these programs can gauge improper racial considerations evident in the legislature’s plan and demonstrate the discriminatory intent that produced such an outcome. As long as the redistricting process remains in the hands of state legislatures, there is a threat that constitutionally impermissible considerations will be employed when drawing district plans. Simulated redistricting provides a powerful tool with which courts can detect a hidden unconstitutional motive in the redistricting process.
Ebola and the Evolving Ethics of Quarantine
Authors: Hughes Daniel
Published: November 2021

Within the context of the history of quarantine, both worldwide and in the United States, this essay analyzes current quarantine policies related to Ebola with an inquiry into both related bio-ethical concerns and an analysis of the ways in which emerging Ebola pharmaceutical treatments, particularly the rVSV-ZEBOV vaccine, may shift quarantine policies. By way of background, the historical roots of quarantine are first briefly examined alongside an analysis of why quarantine policies were not instituted in relationship to the HIV/AIDS pandemic. Then, current quarantine policies and procedures in both the developed and developing world are delineated, with an analysis of the application of these quarantine policies to Ebola. An overview is provided of how new treatment protocols may change Ebola quarantine alongside related bio-ethical concerns.

Gender-Neutral Language in English and French Linguo-Cultures
Authors: Akhvlediani Tsiuri , Kuparadze Giorgi , Gabunia Ketevan
Published: November 2021

Gender linguistics studies the gender-neutral aspect in detail that is usually manifested in a language. One of its provisions tells us that language not only possesses such qualities as anthropocentrism (human orientations) is, but it also implies androcentrism, that is, that it presents a picture of the world based on a masculine viewpoint, in the form of a man (as a personality). The manifestation of such gender asymmetry in the language leads to unequal representation of persons of different sexes and is considered to be intolerant, especially among the members of a foreign language culture.In our paper we deal with the peculiarities of gender-neutral language in English and French linguo-cultures, determine the similarities - the differences between gender-neutral lexis and try to show the cases in which they occur in the process of language interaction. It should be noted that the requirements of political correctness, which are due to non-linguistic reasons, play an important role in the language policy of any country.In conclusion, it should be admitted that in English and French linguistics, the priority to the designation of women in the professional field is given in different ways. Neutral forms are more common (and therefore more widespread) in English whereas in French, however, the forms with inflectional changes or analytical structures of generating nouns are more preferable. Anyway, in European society, language policy and the use of gender-neutral language are greatly influenced by political correctness requirements due to extralinguistic reasons.
Composite as an Alternative Form of Genetive Structure and its Linguistic-Stylistic Features
Authors: Nikabadze Dali
Published: November 2021

The article responds to a recent statement on the weakening of the position of the genitive. Numerous studies have dealt with this question. It should be noted, however, that although the genitive actually retreats in relation to the object, it has a fixed position in relation to the attributive function.The German language is rich in linguistic-stylistic forms that may appear as an alternative to the genitive form. Alternative forms of the genitive, as genitive values, function at different frequencies and degrees. One of their semantic equivalents is composites. The research is based on the latest entomological literature (P. Eisenberg, P. Galman, L. M. Eichinger, A. Heringer), and the illustrated material is taken from online newspapers (such as Spiegel online, Zeit online, Frankfurter allgemeiner Zeitung, Süddeutsche Zeitung. As for the newspaper genre, comments, reports, interviews were used during the research.

Published: November 2021

Фискальные органы во всем мире сталкиваются с уклонением от уплаты налогов как сложной проблемой. Поскольку не существует точных параметров для измерения факторов, влияющих на уклонение от уплаты налогов, авторы, исследующие эту область налогово-бюджетной политики, по-разному интерпретируют их. В ходе изучения тематической литературы было обнаружено, что факторы уклонения от уплаты налогов не были тщательно изучены при сравнении позиций физических и юридических лиц. В данной статье анализируется отношение и восприятие физических и юридических лиц в отношении уклонения от уплаты налогов в Республике Сербия, а также различия между ними. Выявление различий в детерминантах уклонения от уплаты налогов хозяйствующими субъектами позволяет создать оптимальную схему политики противодействия уклонению от уплаты налогов. На основе собранных категориальных данных был применен статистический метод исследования взаимосвязей (связей) между переменными для анализа различий в незаконном пренебрежении налоговыми обязательствами между физическими и юридическими лицами. Такой подход позволил лучше понять социальные группы, которые более склонны к уклонению от уплаты налогов. На основании результатов, полученных с помощью одного из наиболее часто используемых непараметрических тестов в эмпирических исследованиях, был сделан вывод об отсутствии статистически значимой разницы в ответах юридических и физических лиц на отношение в сфере уклончивого поведения в Республике Сербия. Результаты исследования показали, что экономические факторы имеют наибольшее влияние на уклончивое поведение как физических, так и юридических лиц в Республике Сербия.
Виртуальные выставки как актуальная форма музейной коммуникации
Authors: Шаховалова Елена Геннадьевна , Шаховалов Николай Николаевич
Published: November 2021

Развитие музейной коммуникации в условиях внедрения цифровых технологий является необходимым условием музейной деятельности. В формате онлайн стало возможным посетить выставки музеев мира. Вместе с тем в региональных музеях Алтайского края виртуальная выставка как форма музейной коммуникации представлена не в полной мере. На наш взгляд, это обусловлено отсутствием кадров, владеющих цифровыми компетенциями в сфере музейной деятельности. Поскольку данный вопрос остается не изученным, авторами в целях выявления отношения будущих специалистов в музейной сфере к процессам совершенствования форм музейной коммуникации проведено исследование среди обучающихся Алтайского государственного института культуры. В результате выявлено, что будущие музейные специалисты считают виртуальные выставки актуальной формой музейной коммуникации, однако, по их мнению, впечатления несопоставимы с реальным посещением выставки. Сделан вывод о том, что от подготовки новых музейных кадров будет зависеть развитие стратегии любого музея. Результаты исследования могут быть использованы для актуализации образовательных программ профессионального образования, учебных планов по направлению подготовки «Музеология и охрана культурного и природного наследия».
Long-term outcome of cementless total hip arthroplasty with threaded Tropic® acetabular cup and Corail® femoral stem
Authors: Almeida Fernando , Gállego Silvia , Argüelles Francisco , Silvestre Antonio
Published: November 2021

This study investigates the clinical and radiological results of a tapered femoral stem (Corail®) and uncemented threaded acetabular cups (Tropic®) and in addition an analysis of the complications and retrieved implants was conducted. Between January 1990 and September 1998, 301 total hips arthroplasties in 268 patients were implanted. 78 patients (87 hips) had died and 9 patients (12 hips) had been lost to follow-up, leaving at the time of the latest follow-up 180 patients (202 hips). The mean age at surgery was 56,1 (27-75) years. Of the 154 unrevised hips, the median Harris and Merle d´Aubigne and Postel hip scores were 83,3 points and 15,3 points respectively at the latest follow-up. The median follow-up time was 16.9 years (10,4-25). No femoral component was revised for aseptic loosening ; osteolysis was observed in the 9,5% of the implants (13 stems). 48 hips (23%) were revised and 27 cups (56,2%) needed revision surgery because of massive polyethylene wear. Pelvic osteolysis was found out in 80 cups (58,8%). 87 hips (63,9%) showed signs of a progressive wear of the liner, more than 2mm in 48 hips. Kaplan-Meier survivorship analysis at 15 years follow-up was 81.2% with revision for any reason (85.8% for mechanical or radiographic loosening). High rates of polyethylene wear and the high prevalence of pelvic osteolysis are serious matters in these types of implants with high rates of revision at 15 years follow-up so we decided to abandon the concept of a threaded cup design in favor of a press-fit acetabular cup.
Lower total blood loss in total knee arthroplasty with a low-pressure tourniquet than without
Authors: Joufflineau Simon , Thienpont Emmanuel
Published: November 2021

Tourniquet-use has been described in litera- ture as a surgical factor leading to increased post-operative hidden blood loss in total knee arthroplasty (TKA). The hypothesis for this retro- spective study was that low-pressure tourniquet TKA would offer the benefits of tourniquet surgery without the potential negative effects on late blood loss after the procedure. Therefore, this study evaluated total (TBL) and hidden blood loss (HBL) in TKA with or without a tourniquet. We retrospectively compared two groups : one group (n= 54) undergoing TKA without a tourniquet and one group with a low-pressure tourniquet (n= 110). The outcomes compared were hemoglobin levels 2 weeks before surgery and at days 2 and 4 after surgery to calculate total and hidden blood loss, transfusion rate, and functional outcome. A higher total blood loss was observed in the no tourniquet group with a mean loss of 1073 mL against 890 mL in the tourniquet group (p-value = 0,003). Hidden blood loss values between both groups were statistically not significant : in the no-tourniquet group, Hb drop between D2 and D4 was 0.5 g/dL against 0.4 g/ dL in the low-pressure tourniquet group. The tourniquet-less group did not present with better functional scores. This study showed that low- pressure tourniquet use reduces TBL without increasing HBL in TKA.
Outcomes of total knee replacement with the use of a NexGen MIS Tibial Component (Mini-keel) : a systematic review

Published: November 2021

NexGen MIS Tibial Component (Mini-keel) is a tibial component specially developed for minimally invasive surgery in total knee replacement (TKR), and the size limitations of its design and the modular system could affect tibial fixation strength, however, this has not been precisely evaluated thus far. This study aimed to systematically review the literature describing the outcome following TKR with the use of a Mini-keel. Electronic searches of databases were undertaken in July 2019 by two experienced orthopaedic surgeons according to the PRISMA guidelines for literature describing the outcomes of TKR with the use of a Mini-keel. Quality of studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The initial search found a total of 623 studies from all the databases. Seven studies met all the inclusion criteria and were eligible for critical appraisal and quality assessment. In total, 2,198 cases were included in the systematic review.

Thirty-five revision cases due to aseptic loosening were found from the systematic review. Two studies were negative about using a Mini-keel and three studies were positive about it, while the other two studies did not judge the quality of a Mini-keel. There have been conflicting conclusions among studies for the use of a Mini-keel.

There remains a paucity of prospective cohort studies between TKRs with the use of a Mini-keel and those with the use of a conventional implant, which makes it difficult to determine the usefulness and reliability of this implant.
Tranexamic acid use in simultaneous bilateral total knee arthroplasty : a comparison of intravenous and intra-articular applications, which is more effective?
Authors: Öztürk Alpaslan , Akalin Yavuz , Çevik Nazan , Avcı Özgür , Çetin Oğuz , Sağlicak Harun
Published: November 2021

Patients applied with simultaneous bilateral total knee arthroplasty (SBTKA) with the administration of intravenous or intra-articular tranexamic acid (TXA) were compared in respect of blood loss and the need for allogenic blood transfusion.

Of a total 53 patients applied with SBTKA, 32(60%) were administered intravenous TXA and 21(40%) intra-articular TXA. The patients were evaluated in respect of age, gender, height, weight, body mass index (BMI), body blood volume, preoperative and 1,2,3 and 4 days postoperative levels of hemoglobin (Hb) and hematocrit (Htc) and the change in Hb levels, estimated blood loss, mean actual blood loss, the need for allogenic blood transfusion (ABT) and the use or not of a drain.

No difference was determined between the intravenous and intra-articular groups in respect of mean age, gender, height, weight, and body blood volume. No difference was determined between the groups in preoperative and postoperative mean Hb and Hct values, the reduction in mean Hb postoperatively, estimated blood loss, or the need for ABT. No deep vein thrombosis or pulmonary embolism was determined in any patient.

In the application of SBTKA, TXA can be safely administered by the intravenous or intra-articular route to reduce the need for ABT. The results of this study determined no difference in efficacy between the routes of application. For patients with a risk of intravenous use, intra-articular application can be preferred.

«Վահագնի երգը» և հայկական էպոսը Նոր տեսակետ հայկական էպոսի ծագման և ձևավորման վերաբերյալ

Multiple recurrences of the sound combination erk- in the ancient Armenian hymn on the birth of Vahagn, the god of thunder and war, can be considered an anagram of the word erku (two) with an allusion to twins. Moreover, in the expression cov cirani (purple sea) one can see an anagram of Covinar, the name of the mother of the epic twins Sanasar and Baghdasar, first heroes of the epic "Daredevils of Sassoun". In this context it becomes obvious that the image of Sanasar, the elder of the twins, founder of the dynasty of heroes, directly goes back to Vahagn. The same picture of the birth of mythological twins occurs in the ancient epic “Vipasank”.

The article analyses the World Heritage Center activities in the implementation of the pilot project "Astronomy and World Heritage. Thematic Initiative", which was launched in 2003. As part of this project, in 2010, 2019 and in 2021 five objects, related to the astronomical heritage were added to the World Heritage List. However, a detailed study of the UNESCO World Heritage List shows, that it already contains astronomical heritage objects (usually historical observatories), which fit there as part of complex nominations, for example, centers of historical cities or groups of architectural structures, concentrated on historical and cultural territory. Examples of astronomical heritage sites included in the UNESCO World Heritage List are described.
Entrepreneurial Orientation, Innovation and Performance of Value-system Actors
Authors: Kamuri Simon
Published: November 2021

The purpose of this study was to explore entrepreneurial orientation as a cognitive construct attributable to individuals and its relationship with innovation and performance from an industry ecosystem perspective. The study adopted a mixed design approach involving exploration of the factors and a diagnosis of their hypothesized relationships. A mixed sampling of members of a leather industry association and the linked industry institutions was carried out with a 76% response rate achieved. Quantitative data was collected from key decision-makers as informants of firms in Kenya’s leather industry using a questionnaire for guided interviews. The Delphi Technique and a pilot study (Cronbach’s Alpha 0.700 – 0.772) were used to establish instrument reliability. Factor analysis was performed on the study variables using Principal Component Analysis before inferential analysis. Entrepreneurial orientation showed validity as a second-order latent construct comprising three cognitive dimensions, namely vision for growth, opportunity recognition and calculated risk-taking. Entrepreneurial orientation and its antecedents were established as determinants of performance of value-system actors in an industry (R2=0.422, F=13.417, p=0.000). It further showed that this relationship is partially mediated by innovation by the firms (Sobel test Z-value = 3.30449610, p=0.00095147). The study recommends extension of this research to other industries.

This study described the benefits of the Malasakit Center based on the perspectives and experiences of patients of Eduardo L. Joson Memorial Hospital. It employed mixed research methods and interviews as the primary data collection tool. The study was conducted in March 2020 with thirty patients and patient's relatives receiving services of the hospital. Most of the respondents are male and within the age bracket of 30 to 39 years old. All the participants reflected a positive response to Malasakit Center, as it lessened the burden of producing documentary evidences to avail of the services. A procedure observed prior to implementing the Malasakit program. This study also focuses on how the Center made the service more accessible. To further maximize its benefits, information dissemination needs to be widened and its location in the province and in the Philippines should be advertised for increase patronage. Posting of the requirements for availment of Malasakit Center services is likewise essential and may considerably increase the number of applicants for the services of the Center.

O presente estudo tem como objetivo avaliar a atividade antibacteriana e moduladora do óleo essencial de Allium sativum L. (OEAs) associado às luzes de LED. O óleo essencial foi obtido por hidrodestilação e a atividade antibacteriana e moduladora foi executada pelo método de contato gasoso com o uso de luz de LED amarela, azul e vermelha junto com os antibióticos amicacina, ciprofloxacina, gentamicina, norfloxacina, oxaciclina e penicilina. Os testes foram feitos em triplicata e submetidos à análise estatística ANOVA com teste de significância para p<0,05. Para a atividade antibacteriana não houve inibição do crescimento das cepas testadas e para as combinações OEAs + antibiótico + luzes de LED (modulação da resistência antibacteriana) diante de linhagens multirresistentes de Escherichia coli 27 e Staphylococcus aureus 358 o melhor desempenho se mostrou com os antibióticos ciprofloxacina e norfloxacina, respectivamente. Esses resultados tornam-se importantes na colaboração com futuras pesquisas para novas formas de tratamento de doenças provocadas por bactérias multirresistentes.
La Historia Oral como enfoque metodológico para la reconstrucción histórica del COBACH: el sistema escolar como dispositivo y aparato ideológico de Estado
Authors: Salcido Sáenz Marilyn Georgia , Trujillo Holguín Jesús Adolfo
Published: November 2021

El presente trabajo hace un primer acercamiento metodológico al estudio doctoral denominado inicio y consolidación del Colegio de Bachilleres del Estado de Chihuahua (COBACH), institución que se caracteriza por ser la primera opción de ingreso al nivel medio superior en la entidad. Igualmente, se toma a la Historia Oral como enfoque metodológico, debido a que la fundación de esta institución forma parte de la historia reciente, por lo que resulta valioso rescatar los testimonios de las personas que formaron parte de este hecho para su reconstrucción histórica y así poder adentrarse en el contexto que vio nacer a este organismo por medio de las vivencias de los participantes. Adicionalmente, este trabajo hace una relación con los conceptos que utiliza Agamben y Althusser sobre dispositivos y aparatos ideológicos del Estado, los cuales hacen referencia a como el aparato escolar cumple una función primordial para mantener las relaciones de poder para la sociedad política y civil.
