THE STRATEGIC EFFICACY OF DRONES FOR US GRAND STRATEGY
Authors: Okpaleke Francis N , Okoli Al Chukwuma
Published: January 2021

This paper assesses the role of drones in furthering or undermining US grand strategy. This is against the backdrop of the thinking that contemporary use of drones in the context of post 9/11 era undermine the successive US administration’s strategic objectives as evidenced by the rise of anti-Americanism in Muslim world, proliferation of drones by US near peer competitors, civilian death toll and weakening support for the US in targeted countries. This implies that while drones has played a historical and significant role for the US in power projection and asserting its unilateralism and military hegemony when dealing with rogue states and terrorist groups post 9/11, the political and strategic utility of drone strikes for US grand strategy is not apparent. Thus, this paper posits that though armed drones has played a quintessential role as a key instrument of statecraft for facilitating US offensive strategy in targeted states, the aftermath of drone strikes and its controversial aspects engender inimical outcomes that serve to undermine US strategic objectives. Based on qualitative analysis of secondary data, the paper questions the wisdom and benefits of using and shifting greater reliance towards armed drones, as a pathway for furthering US grand strategy.
An Un-operated d-TGA Case Holding On To Life
Authors: Solmaz Hatice
Published: January 2021

Complete transposition of the great arteries is incompatible with life
without corrective surgery in the neonatal period. Even in the presence
of large intracardiac shunts, a case of un-operated d-TGA that survived
to late adulthood is thought-provoking. We described a case of
un-operated d-TGA presenting at 46 years of age who had large secundum
type ASD, pulmonary hypertension, pulmonary artery aneurysm, situs
inversus, mirror image dextrocardia and abnormal origin of the coronary
artery. The management of an un-operated case of d-TGA surviving to late
adulthood has made it important to share case-based experiences as there
are no evidence-based data.
Casa, Escuela y Ciudad: el cultivo del lenguaje en un mundo digital
Authors:   Universidad Complutense de Madrid, González Martín M. Rosario , Jover Gonzalo ,   Universidad Complutense de Madrid, Torrego Alba ,   Universidad Autónoma de Madrid
Published: January 2021

This paper aims to show the importance of language and the challenges it faces in the digital revolution by considering the possibilities for cultivating it during adolescence in three fundamental spaces: Homes, Schools, and Cities. It starts by analysing the dual function of language as a means of both communication and representation, as how one receives one’s heritage and imagines and projects one’s future. It then considers the false dichotomy between digital competency and reading skills in light of the latest results from the Programme for International Student Assessment (PISA). Reading can no longer be understood just as the ability to enjoy dusty volumes of old classics languishing on library bookshelves. Rather, it can be defined as a set of strategies that enable personal development and participation in society. This extension of the concept inexorably involves the competence of acting creatively in digital environments. Unfortunately, these environments go largely unheeded at School, where they are relegated to the mundane world of play. At Home, however, digital discourse can be experienced as unfathomable, where the digital divide makes it a world apart. Therefore, collaboration between School and Home becomes vital for ensuring that adolescents’ immersion in the digital world leads to critical, responsible participation in citizenship.

Published: January 2021

Intelligence is considered to be the ability to understand, reason, and make decisions based on a given situation. Neuroeducational advances in recent decades show that physical activity is a key variable for adequate development of intelligence, especially during the complex stage of adolescence. Numerous cross-sectional studies have considered the link between physical activity and intelligence, and the effects on intelligence of longitudinal physical activity intervention programmes have been analysed in several systematic reviews and meta-analyses. However, there have been fewer studies focussing on a more theoretical/epistemological approach and the development of specific practical proposals for didactic interventions within the educational setting. This work aims to show the most relevant scientific results relating to the association between and effects of physical activity on intelligence and it offers didactic guidelines and suggestions for the use of physical activity as a means of cultivating intelligence in a school setting. For this purpose, strategies based on increasing daily physical activity and physical fitness, the comprehensive use of physical education classes, active commuting to school and active school starts, active breaks and recesses, and finally the combined teaching of physically active academic sessions, are shown.
Biochemical markers in saliva in patients with oral cancer
Authors: Andjelski-Radicevic Biljana , Dozic Ivan
Published: January 2021

Head and neck cancers account for 3% of all human cancers and are mainly
localized in the oral cavity. Early detection of cancer is extremely
important for reducing mortality and morbidity from this disease. In
addition to clinical trials and histopathological findings, in the last two
decades, with technological development, more specific and sensitive methods
have been used in the analysis of salivary markers. The aim of this study
was to present a wide range of analyzed markers in saliva: different protein
markers (total proteins, albumin, defensins, staterin, cystatins),
epithelial and molecular markers (CA125, CA19-9, TPA, CEA, CYFRA 21-1,
CD44), enzymes (LDH, ALP, MMP, SOD), cytokines (IL-6, IL-8, IL-1?, TNF-?),
oxidative stress markers (8-OHdG, MDA), non-enzymatic antioxidants
(glutathione, uric acid, albumin, vitamin C and E) etc. Collecting saliva is
simple and painless for the patient, it does not require expensive equipment
or specially trained staff, and it is possible to take saliva several times
and in unlimited quantities. Extensive research that is increasingly being
done with modern techniques indicates that saliva may be useful for early
detection of the disease in the near future.
Shareholder Value Implications of the Internal Audit Function
Authors: Liu Bo
Published: January 2021

SYNOPSIS

In 2013, NASDAQ Stock Market LLC (NASDAQ) issued a proposal to mandate the internal audit functions (IAFs) for all listed companies but later withdrew the proposal. In this study, I investigate whether the mandatory IAF adds shareholder value and how the value implications vary across companies. For companies without IAFs before the proposal, I document a positive (negative) price response to the NASDAQ IAF proposal filing (withdrawal). This evidence suggests that, on average, investors perceive mandatory IAF as value enhancing. I find that the positive market reaction is concentrated among firms with lower external audit quality and institutional ownership. Additionally, I document that the return responses are higher for companies with smaller book-to-market ratios, multiple business segments, and lower Altman z-scores. Those results suggest that investors' perceptions of the mandatory IAF are more positive for weakly monitored firms, firms with high-growth prospects and complex business, and firms in financial distress.
Big 4 Firms as Legal Service Providers: Implications for Audit Practice and Future Research Directions

Published: January 2021

SYNOPSIS

The Big 4 accounting firms have expanded their legal service arms to historic proportions over the last decade, employing thousands of lawyers around the world. Although most of the Big 4's revenue from legal services is presently generated outside the U.S., they are now making inroads into the U.S. legal market, and rule changes are being considered that would further allow the Big 4 to offer legal services in the U.S. This essay summarizes the current status of Big 4 firms as legal service providers, discusses potential implications of legal offerings for their U.S. audit practices, and suggests directions for future research. Our proposed research questions are informed by several literatures, interviews with former Big 4 partners and practicing attorneys, and a survey of the general public. They center on the fundamental difference between audit and law practices, brand equity considerations, and culture changes within the Big 4.
Signaling through Dynamic Thresholds in Financial Covenants
Authors: Chava Sudheer , Fang Shunlan , Prabhat Saumya
Published: January 2021

Among loan contracts originated during 1996–2015 with covenants, 37 percent have financial covenant thresholds that automatically tighten according to a predetermined schedule. Firms that accept dynamic covenant thresholds improve their creditworthiness, but they are more likely to violate covenants relative to matched control firms. In the event of a covenant violation, these firms are less likely to receive a waiver. They also tend to pay higher waiver fees, experience greater investment cuts, reclassify more debt as callable within one year, and they are more likely to switch lead lenders. Overall, our findings suggest that, on average, signaling through dynamic thresholds in covenants is credible but costly to borrowers should they fail to deliver the signaled performance.

Published: January 2021

In order to study the interaction between a femtosecond laser and a titanium film, the method of combining the two-temperature model and molecular dynamics was used to simulate the ablation and spallation of the titanium film by the femtosecond laser with a wavelength of 800 nm. The spallation of the titanium film was explained from the perspective of the temperature and the stress wave. It is found that the femtosecond laser with a pulse width of 300 fs loads the titanium film, and the ablation threshold is around 0.05 J/cm2. The effects of different pulse widths in the range of 100–500 fs and different energy densities in the range of 0.10–0.20 J/cm2 on the spallation results of titanium films were also studied. We found that the femtosecond laser with a pulse width of 100 fs promotes the spallation phenomenon to occur more quickly. The surface spallation products of the titanium film were large clusters of atoms when the energy density is 0.10 J/cm2, but most of the surface spallation products of the titanium film were single atoms when the energy density is 0.20 J/cm2. These indicated that the energy density is an important factor affecting the spallation products of the titanium film. The evolution of maximum electron temperature, electron-lattice equilibrium temperature, and coupling time with pulse width and energy density are also given and analyzed. These results have important reference significance for studying the fracture and damage of titanium, and they help us to understand the mechanism of femtosecond laser processing materials.
EL CINE BOLIVIANO SOBREVIVIENDO AL COVID-19: LA PERCEPCIÓN DE LOS REALIZADORES SOBRE LOS EFECTOS DE LA PANDEMIA
Authors: Laguna-Tapia Andrés
Published: January 2021

En el presente artículo se busca describir el efecto que tuvo la pandemia en el sector audiovisual boliviano, en el primer semestre de 2020, un periodo agravado por múltiples factores, entre ellos, la crisis política e institucional desatada en octubre-noviembre de 2019, una baja cultura digital, una importante brecha digital y una realidad socioeconómica compleja. Este es un trabajo de naturaleza exploratoria y cualitativa, que principalmente recolectó la información a través de fuentes primarias. Es decir, a través de los testimonios de realizadoras, realizadores, productoras y productores de distintos lugares de Bolivia. La herramienta fundamental para la recolección de datos fue la entrevista semiestructurada, probablemente la metodología más utilizada en investigaciones de naturaleza cualitativa. Se concluye que, desde la perspectiva de los realizadores, los efectos de la pandemia sobre el audiovisual boliviano fueron agravados por la crisis política y por una deficiente gestión del gobierno de transición. Por otro lado, los procesos de transformación de los modos de producción, de distribución y de comercialización, acelerados por la pandemia, deben ser
asumidos, repensados y asimilados desde el contexto boliviano, como, por ejemplo, el uso de plataformas de VOD. Finalmente, se constató una tendencia en los realizadores nacionales, creen que el cine boliviano debe comprometerse con la realidad social y con el diálogo con el otro.
UNEXPLAINED WAGE GAPS IN THE TRADABLE AND NONTRADABLE SECTORS: CROSS-SECTIONAL EVIDENCE BY GENDER IN BOLIVIA
Authors: Molina-Tejerina Oscar , Castro-Peñarrieta Luis
Published: January 2021

This document analyzes the gender wage gap between in tradable and non-tradable sectors. The tradable sector is defined by the value of exports and imports in an industry based on the four-digit codes of the International Standard Industrial Classification. Based on Gary Becker's work, in an economy prone to discrimination against women, the document proposes a model from which discrimination is possible if companies generate supra-normal profits. These benefits will be determined by market power, which in turn depends on the number of companies participating in the industry, so under the assumption that tradable sectors are directly influenced by international trade and with the possibility of greater competition, this competition will generate a trend towards normal benefits, making it impossible to finance discrimination against women, so the wage gender gap should be lower in tradable than non-tradable sectors. Using the traditional Oaxaca-Blinder decomposition and the Oaxaca-Blinder decomposition with Recentered Influence Function (RIF) regressions for the 2013 Household Survey, we find that unexplained wage differences against women are significantly lower in the tradable sector, suggesting that the impact of international trade on the tradable sector helps to reduce the gender wage gap in Bolivia.

Authors: Melo Teresa , dos Santos Liliana Ribeiro , Martins Patrícia , Vilas Ana Paula
Published: January 2021

Background:

Vitamin B12 (VB12) deficiency is a pleomorphic disease with a wide range of manifestations. Its major cause is pernicious anemia, an autoantibody-mediated disease that results in low levels of intrinsic factor.

Case Presentation:

We present a case report of a middle-aged man with severe megaloblastic anemia due to VB12 deficiency in relation to an unsuspected Crohn’s disease with exclusive ileum involvement. He also had some unusual neurological manifestations of this vitamin’s deficiency, such as hypersudoresis. Unlike most cases, the anemia was not hypoproliferative and hemolysis existed.

Conclusion:

This case reports some unusual aspects of VB12 deficiency and reminds us that ileum disease should be considered in patients with a negative autoimmune profile.

Defining the family of a child with disabilities
Authors: Filippova Veronika
Published: January 2021

The article provides an overview of the scientific literature, concepts of psychologists, teachers, sociologists who define the family as a social institution, small group or system. The forms and types of families are considered depending on social development, educational impact on the child, and the composition of members. The definition of the family of a child with disabilities is given by describing the features of difficult life situations and the phenomenon of family. As a result, it is concluded that the family of a child with disabilities on the one hand meets the totality of family characteristics as a social phenomenon, and on the other has its own characteristics due to the impact on its life activity of having a child with disabilities. For this reason, the family can both become the main developmental resource for the child, and limit its rehabilitation potential.
Adopting Criteria for Determining the Value of Compensation for Workers in the Construction Sector in Iraq As a Result of Work Accidents
Authors: Ibrahim Abdulrahman Adnan , Sultan Farah Awad
Published: January 2021

Safety programs are a humanitarian message developed by government bodies to protect the human race from various accidents and injuries as well as protecting all property from machinery, equipment and various materials. Despite the interest of the countries of the world and especially the developed countries in the subject of occupational health and safety, this topic did not receive the attention required by the higher departments in most of our construction sites. This research aims to adopt criteria to determine the value of compensation of workers in the construction sector in Iraq as a result of work accidents. In this research several means were used to verify the value of compensation for workers in the construction sector in Iraq, such as using the questionnaire as a means of determining compensation criteria for injuries resulting from work accidents. The sample of the research was selected from engineers with experience in implementing construction projects and employees working in other specialties such as (judiciary, law and health), Where (31) persons who are directly related to the subject of the research. Some statistical methods (arithmetic mean, standard deviation, coefficient of variation, relative importance, truthfulness test, and stability) were carried out, through which the data were processed, and the results were interpreted accordingly. The value of financial compensation was extracted for the injuries suffered by workers as a result of work accidents (Working days) and according to criteria extracted based on the results of the questionnaire, in order to prepare stable standards of compensation that can be relied upon at any time and place, and for all construction projects in all Iraqi provinces. This research concludes that the lack of a clear system for compensating work injuries in construction projects and the adoption of compensation for personal and several considerations (regional and tribal) and others.

This paper submits a comprehensive review of previous studies that discussed the properties and performance of utilizing PPF in normal and high strength concrete, recycled aggregate concrete and hybrid fiber concrete.
Thermodynamically consistent Darcy–Brinkman–Forchheimer framework in matrix acidization
Authors: Wu Yuanqing , Kou Jisheng , Sun Shuyu , Wu Yu-Shu
Published: January 2021

Matrix acidization is an important technique used to enhance oil production at the tertiary recovery stage, but its numerical simulation has never been verified. From one of the earliest models, i.e., the two-scale model (Darcy framework), the Darcy–Brinkman–Forchheimer (DBF) framework is developed by adding the Brinkman term and Forchheimer term to the momentum conservation equation. However, in the momentum conservation equation of the DBF framework, porosity is placed outside of the time derivation term, which prevents a good description of the change in porosity. Thus, this work changes the expression so that the modified momentum conservation equation can satisfy Newton’s second law. This modified framework is called the improved DBF framework. Furthermore, based on the improved DBF framework, a thermal DBF framework is given by introducing an energy balance equation to the improved DBF framework. Both of these frameworks are verified by former works through numerical experiments and chemical experiments in labs. Parallelization to the complicated framework codes is also realized, and good scalability can be achieved.

energy sector development. To provide a high quality of such decisions, intellectualization of the process of making them is required. This article deals with usage of agent-service approach for development of intelligent decision support systems (IDSS). Concepts of agent and multiagent system are being considered. Detailed description of agentservice approach and architecture of a typical IDSS, used in this approach, is provided. Also, article considers usage of agent-service approach for development of IDSS “Situation polygon” (for strategic decision-making support in energy sector) and web-oriented information-analytical system WIS (for impact assessment of the energy sector on geoecology). In the future, we plan to add additional functionality in these systems, in particular, to provide in the “Situation polygon” an automatic setting of the values of connections in cognitive maps based on the values of connections in the ontology, and to add in WIS the possibility of calculating the trajectory of the transfer of harmful substances.

O objetivo principal deste estudo foi avaliar a adesão à higienização das mãos (HM) entre a equipe multiprofissional em saúde das Unidades de Terapia Intensiva (UTI) de um hospital referência para pacientes portadores de doenças infectocontagiosas na Amazônia brasileira. Tratou-se de um estudo retrospectivo analítico de aspecto quantitativo baseado em informações secundárias obtidas dos formulários de observação de higiene das mãos arquivados no banco de dados da Comissão de Controle de Infecção Hospitalar (CCIH). Os resultados obtidos mostraram, que durante a comparação estatística da adesão da higienização das mãos dos cinco momentos entre a equipe multiprofissional das duas Unidades de Terapia Intensiva para adultos e pediátricos que a adesão média na UTI para adultos foi de 30,76 % e na UTI para pediátricos de 28,92 %. Chega-se a conclusão que se deve desenvolver medidas visando à maior utilização dessa rotina básica de prevenção de infecções hospitalar pela equipe multiprofissional em saúde. Higienizar as mãos, conforme preconizado, consiste no primeiro passo para a busca da segurança e da excelência na qualidade da assistência ao paciente.
Importância da assistência de enfermagem para a promoção do aleitamento materno

O objetivo geral deste artigo é dissertar sobre a importância da assistência em enfermagem para estimular a promoção ao aleitamento materno. O aleitamento materno é uma prática reconhecida cientificamente como responsável pelo atendimento de todas as carências nutricionais do recém-nascido e incide diretamente sobre a redução da taxa de mortalidade infantil. Além disso, proporciona benefícios físicos e emocionais para mãe e bebê, mas apesar dos seus benefícios o aleitamento materno não é realizado por muitas mães. A atuação dos profissionais da enfermagem é fundamental para a difusão dessa prática e consiste em um conjunto de ações educativas destinadas às mães e seus familiares. Dentre os profissionais da equipe multiprofissional de saúde, os(as) enfermeiros(as) atuam diretamente na promoção do aleitamento materno, difundindo conhecimentos e práticas às mães e aos seus familiares e dessa forma contribuem diretamente para a promoção da saúde e qualidade de vida de lactentes e lactantes.

Management of Darier disease: A review of the literature and update
Authors: Haber Roger N. , Dib Nicole G.
Published: January 2021

Darier disease (DD) is a rare type of inherited keratinizing disorder with no definitive therapeutic approach. The objective of this study is to provide a detailed literature review of all the available treatment modalities of Darier disease, including those that are both surgical and non surgical, to compare their efficacies and to propose a novel therapeutic approach. A complete search of the literature for all articles describing the different treatments of Darier disease, with no restrictions on patients’ ages, gender or nationalities, was performed with the use of PubMed. A total of 68 articles were included in the study: 3 prospective studies, 44 case reports/case series and 21 letters/correspondences/clinical images. The treatments described were topical, oral or physical. Retinoids (isotretinoin, tazarotene and adapalene) and fluorouracil were the two most effective topical treatments. Oral retinoids were the most effective oral therapy and were prescribed in the cases of generalized Darier disease. For localized and resistant skin lesions, physical therapies including surgical excision, dermabrasion and CO2 laser ablation were the first line choices. Limitations of this article include the inability to verify the accuracy of the published data, the relatively small sample size, the absence of randomized controlled clinical trials and possible unidentified confounding factors in various studies. In every therapeutic approach to Darier disease, consideration of patient comorbidities, disease distribution, severity and treatment accessibility is essential. Large and randomized clinical trials are necessary for the comparison of the efficacy and the safety of all the treatments of Darier disease and settling a consensus for management.
Synthetic biology yields a dinuclear copper based antibody for the naked-eye detection of glyphosate
Authors: Rossel Thibaud , Creus Marc
Published: January 2021

The design and construction of synthetic antibodies capable of recognizing selectively antigens is an important challenge for synthetic biology and bio-engineering. Here, we develop a step towards the construction of de novo synthetic antibodies using a new combinatorial based approach. The bioconstruct incorporates supramolecularly a self assembling inorganic complex into a protein thus creating a modular and evolvable receptor. We used a dinuclear copper based inhibitor of carbonic anhydrase to program host-guest recognition, which in the presence of glyphosate generates a selective naked-eye sensing. The construct was used to detect the pesticide in complex samples. Taken together, our results provide new opportunities for the combinatorial optimization and evolution of our synthetic antibodies. Our assay is geared and designed specifically towards the mimic of natural antibodies but with features reminiscent of both synthetic biology and inorganic chemistry. In the near future, we anticipate evolution and artificial intelligence protocols dedicated to fine tune our host for the optimal recognition of a multitude of analytes.
