Can Online Presence Give Companies a Competitive Edge?
Authors: Szucs Krisztian
Published: November 2020

In this study the competitiveness of Hungarian enterprises was analyzed, because relatively little research has been conducted to investigate small enterprises. More specifically, the paper examines to what extent the use of online solutions gives companies a competitive advantage. Nearly 800 companies were involved in the research, for which a new methodology was used. It is built on a multi-step model, which is based on mathematical calculations. From the result of a questionnaire survey, variables were generated to create a number of competitiveness pillars, which were used to determine the final competitiveness index of each company. The research was carried out at the Faculty of Business and Economics, University of Pécs. Scientists form the Faculty of Engineering and Information Technology, University of Pécs were involved in the online analysis of the companies, the results of which were integrated into the research findings. The analysis shows that the companies, which do not use online solutions during their operations can be competitive but generally those present in the online space are more competitive, and use more sophisticated solutions in their business processes, which has a positive effect on several functions of the company. Overall these companies have a higher competitiveness index, which confirms that it is worth using online solutions for companies.
Parametric Study of Damping Characteristics of Magneto-Rheological Damper: Mathematical and Experimental Approach
Authors: Wani Zubair Rashid , Tantray Manzoor Ahmad
Published: November 2020

The present research work is a part of a project was a semi-active structural control technique using magneto-rheological damper has to be performed. Magneto-rheological dampers are an innovative class of semi-active devices that mesh well with the demands and constraints of seismic applications; this includes having very low power requirements and adaptability. A small stroke magneto-rheological damper was mathematically simulated and experimentally tested. The damper was subjected to periodic excitations of different amplitudes and frequencies at varying voltage. The damper was mathematically modeled using parametric Modified Bouc-Wen model of magneto-rheological damper in MATLAB/SIMULINK and the parameters of the model were set as per the prototype available. The variation of mechanical properties of magneto-rheological damper like damping coefficient and damping force with a change in amplitude, frequency and voltage were experimentally verified on INSTRON 8800 testing machine. It was observed that damping force produced by the damper depended on the frequency as well, in addition to the input voltage and amplitude of the excitation. While the damping coefficient (c) is independent of the frequency of excitation it varies with the amplitude of excitation and input voltage. The variation of the damping coefficient with amplitude and input voltage is linear and quadratic respectively. More ever the mathematical model simulated in MATLAB was in agreement with the experimental results obtained.
Focusing of Light Pulses by Different Types of Wavy Parabolic Mirrors
Authors: Nyitray Gergely , Elter Patrik
Published: November 2020

The propagation of an ultra-short light pulse is studied in the framework of scalar diffraction theory. Light pulses are focused by different types of wavy parabolic surfaces. The temporal-spatial behavior of the two-dimensional wave field is computed in the vicinity of the focal plane. It is shown that the slightly perturbation from the perfect parabolic shape leads a space-time dispersion of the pulse in the neighborhood of the focus.

Experiential knowledge
Authors: Peter Beate
Published: November 2020

This article is concerned with the retrieval of sources in popular music historiography. It discusses the methodological and conceptual challenges that popular music historians might encounter when faced with cultures or practices that cannot be fully captured through conventional paradigmatic principles of the treatment of sources. Discussing an over-reliance on written documentation and a focus on what is identified as theoretical knowledge, a case is made for the inclusion of experiential knowledge as source for popular music history. Understood to be contextualized knowledge that can only be gained through participation in a music event, the article identifies dance as a form of experiential knowledge, which can be used to describe and explain music events such as raves. Understanding dance as/in memory provides opportunities to establish stronger links between the sociology of everyday life and the historical treatment of events.
‘On the programme tonight’
Authors: Bennett Andy
Published: November 2020

British popular music television series The Old Grey Whistle Test (OGWT) was a regular feature on BBC2 between 1971 and 1987. The show enjoyed its greatest popularity during the early 1970s when, as a programme synonymous with the term album-orientated rock (AOR), it was responsible for introducing British popular music audiences to a different range of music than was generally featured on national television and radio at the time. Despite its iconic and relatively unique status during the early 1970s, however, little has been written about OGWT. The purpose of this article is to examine and assess the significance of OGWT in terms of its critical role as a tastemaker for British AOR audiences during an era where opportunities to listen to AOR on British television and radio were limited. The article also considers the legacy of OGWT in the digital age where its significant archival footprint on YouTube has given the show a renewed level of importance as a comprehensive retrospective guide to the AOR music of the early 1970s.
‘Well-worn grooves’
Authors: Taylor Iain A.
Published: November 2020

Recorded music, as both aesthetic listening experience, and as material culture, has a deep mnemonic resonance for a great many people. Starting from Csikszentmihalyi’s (1993) theorization on the significance of artefacts in the structuring of ‘well-worn grooves’ of consciousness, this article considers the biographical function of the metaphorical (and literal) ‘well-worn grooves’ of music-based artefacts such as records. Building upon existing arguments from material culture studies and popular music studies, this article uses excerpts from research interviews with self-identified ‘music enthusiasts’ to argue that an attentiveness to the complex and intertwined relationships between popular music listening, and its materiality, presents possibilities for looking beyond a broadly canonic understanding of popular music history, arguing for a greater attentiveness to the richness of individual music-based biographies as a means of exploring the relationship between popular music and the past.

Right of Way Integrated Vegetation Management: Essential to Keep the Us Economy Moving
Authors: Byrd John D. , Maddox Victor , Russell David
Published: November 2020

Transportation and utility rights of way represent an often overlooked yet sizeable land mass across the U.S. that transects diverse topographies and ecosystems. These land uses, along with the necessary safety, drainage, and load bearing features, present unique challenges for vegetation
management, especially on transportation rights of way. An integrated approach to vegetation management is essential to maintain the functionality of these corridors and should be part of the initial right of way design, but once constructed, mechanical and chemical control are the primary
tactics to manage undesirable vegetation.
Effects of Climate Change on Crops and Weeds: The Need for Climate-smart Adaptation Paradigm
Authors: Korres Nicholas E. , Dayan Franck E.
Published: November 2020

The net effect of climate change on agriculture is likely to be negative despite the potential beneficial effects some crops and regions might receive. While increases in atmospheric CO2 are projected to stimulate growth in C3 crops and improve water use efficiency in C4
crops, climate impacts, particularly temperature increase, heat waves, droughts and flooding, will probably reduce yield potential. These negative effects will be compounded by increased weed interference and competition with the crop. The new type of "carbon farmer" should adapt to climate
change and implement farming practices that focus on agricultural production models that mitigate climate change and promote "nature" and sustainability. Everything is already at least possible in one form or another, and the challenge is now to make it a reality.
Antimalarial Drugs as Inspiration for Herbicides
Authors: Mylne Joshua S. , Stubbs Keith A.
Published: November 2020

In addition to good stewardship, the unabated rise in herbicide resistance and dearth of truly new herbicides demands that new molecules be found. Over 30 years ago, a chloroplast-like organelle was found in the malarial parasite Plasmodium falciparum and herbicides demonstrated
a close relationship existed to plants. Recently this idea was turned on its head by exploiting the boom in malaria research to search for new herbicide chemistry and it provided interesting starting points for development. The merit of such an approach is underlined by tetflupyrolimet, the
first truly novel herbicide in 30 years, and whose target has been a popular subject for antimalarial drug development for 15 years. Which other antimalarial targets, drugs and drug leads might reach across the parasite-plant divide to inspire new herbicides?
What Makes a Weed a Weed? How Virus-mediated Reverse Genetics Can Help to Explore the Genetics of Weediness
Authors: MacGregor Dana R.
Published: November 2020

Reverse genetics investigates what a gene does by testing how the plant responds when the specific gene is changed. These techniques have been in use for decades to assess whether a given gene underpins interesting phenotypes and gain insight into the function of gene networks and families.
Weed science has only recently entered the "genomic era" in which genomic and reverse genetics approaches are used to address hypotheses. This review focuses on two reverse genetic techniques used on a variety of plants including agricultural weeds, virus-induced gene silencing (VIGS) and
virus-mediated overexpression (VOX), explaining the biology behind them and highlighting how these tools may be used for gene function validation in weed species for which no other transgenic approaches have been developed.
Some Views on Current Concerns About Pesticides
Authors: Matthews Graham
Published: November 2020

There is little doubt that the introduction of modern pesticides since the end of the Second World War has enabled a significant increase in the production of many crops during the green revolution, but criticism of the use of pesticides has increased because more people are claiming
that their use has resulted in unacceptable adverse impacts on the health of those applying the pesticides or who live near treated farms, as well as more general impacts on the environment. When these modern pesticides were first introduced, countries established registration requirements.
These were based on scientific data at that time concerning their toxicity and persistence in the environment, and have been followed to a variable degree, depending on whether individual countries or regions had adequate facilities to assess the data presented by manufacturers.

Authors: Acosta Bohorquez Juan Carlos
Published: November 2020

La propuesta de esta Investigación es analizar cuáles son las estrategias de internacionalización de la educación superior que están aplicando las universidades en Colombia, para acceder al mercado académico global cada día más exigente y competitivo.

La internacionalización de la educación no debe concebirse como una serie de procesos aislados donde algunos estudiantes tienen la oportunidad de experiencias académicas fuera de su país; sino se debe ver como un proceso de planificación y de expansión para que toda la comunidad académica participe constantemente de las estrategias didácticas a nivel de educación superior.

En el desarrollo de la presente investigación, se abordan diferentes estrategias que sirven como punto de partida en los procesos de internacionalización de las instituciones de educación superior (IES) colombianas.

Teniendo en cuenta que las relaciones internacionales son herramientas para promover alianzas de cooperación, apoyo a los proyectos de formación docente, extensión e investigación. Se analiza la internacionalización de la educación desde la perspectiva de las políticas institucionales propuestas para la transformación del currículo educativo.

Authors: Lasso Silva Edel Rocío , Rojas Álvarez Sonia Patricia , Pinzón Sierra Duván Fernando
Published: November 2020

La reforma tributaria contenida en la Ley 1819 de 2016 y su decreto reglamentario 1650 de 2017, fueron relevantes en Colombia para la estructuración de un esquema fiscal con perspectiva del conflicto armado- toda vez que se definieron las Zonas más Afectadas por el Conflicto Armado (ZOMAC), como estrategia para reactivar las regiones que han sufrido las acciones negativas de los grupos armados al margen de la ley. El proceso de acuerdo de paz en Colombia busca la construcción de la paz territorial y ambiental, estimulando la creación de nuevas empresas o negocios, las ZOMAC, generando incentivos de tipo tributario específicamente en el impuesto sobre la renta y complementarios, por el hecho de iniciar actividades en estos municipios.

Esta investigación busca comprender los aspectos sociales y tributarios durante los años 2017 y 2018 en las ZOMAC. La investigación presentada es de tipo documental y se propone como un artículo de revisión. Se construyeron las categorías necesarias para el análisis e identificación de los trabajos efectuados en torno a las ZOMAC. De los 27 trabajos de investigación analizados se destaca, en primer lugar, que estos corresponden en un 59,26% a investigación formativa, corroborando el interés en estudiantes de pregrado, especialmente de la disciplina de contaduría; en segundo lugar, los conceptos con mayor importancia son: impuestos, renta, conflicto armado, posacuerdo, posconflicto, los sectores rurales que desarrollan actividades agrícolas y agropecuarias y aspectos sociales. Por último, la metodología que se presentó en las investigaciones documentadas corresponde en un 80% de los trabajos al enfoque cualitativo y de tipo descriptivo.
¿Cómo gerenciar un proyecto a través de la matriz Vester en planificación estratégica? Caso: explotación minera en Timbiquí (Cauca)
Authors: Rodríguez Restrepo Víctor José
Published: November 2020

El trabajo de investigación es la representación de una problemática vigente en el Departamento del Cauca con su población afro-indígena-campesina. Esta población se ha visto afectada por la escasa oportunidad laboral y es aprovechada por los diferentes grupos al margen de la ley en la explotación de la minería ilegal. El trabajo tiene por objetivo mostrar a través de la aplicación de la matriz de Vester, herramienta de la planificación estratégica, que tan posible es determinar el problema central, sus causas y efectos sobre el manejo inadecuado de los recursos naturales, quiénes son los protagonistas del desequilibrio que se registra en la región. Finalmente se plantea unas posibles alternativas de acción por parte de los interesados para corregir el problema que perjudica a sus pobladores y al manejo de los recursos naturales así: i) La legalización, control y apoyo tecnológico por parte del estado para reglamentar la minería artesanal, ii) capacitación y formalización del personal adecuado con las competencias para la explotación minera controlada y iii) exigir a las compañías mineras extranjeras un mayor aporte en impuestos y responsabilidad social para el país.

Un directivo que trabaja la planificación estratégica en el campo de lo social debe orientar su toma de decisiones hacia el uso y la aplicación de las competencias directivas para llevar a la ejecución un plan de acción en donde se permita ejercer la justicia, las normas ambientales y la condición legal del trabajo de sus habitantes y gobernantes. Para evidenciar lo anterior, se describe el caso: Explotación minera en Timbiquí (Cauca).
El documento se inicia presentando los aspectos teóricos de la planificación estratégica y termina con un ejercicio práctico de la situación.

Breyten Breytenbach, A Monologue in Two Voices/Sandra Saayman
Authors: Carolin Andy
Published: November 2020

In A Monologue in Two Voices, Sandra Saayman argues that Breyten Breytenbach’s poetry and prose should be read alongside his paintings and drawings. The book focuses particularly on the literary and visual texts that Breytenbach produced during and about his imprisonment in the 1970s and 1980s. Saayman considers not only representations of the personal experiences of the author/artist but she also identifies instances in which Breytenbach engages with broader political issues including the death of Steve Biko, progressive Afrikaner identities, and postapartheid nationalism. Much of the book’s archival and academic value lies in its beautiful reproductions of more than 40 of Breytenbach’s drawings and paintings, including nine pencil drawings that have never before appeared in print.
Montessori Literature Through the Lens of Leadership
Authors: Bennetts Karen , Bone Jane
Published: November 2020

This article reviews the Montessori literature through the lens of leadership, using Maria Montessori’s writings for a perspective on leadership aligned with her principles and practices. Dr. Montessori was a strong leader who argued that adults, as leaders, should take direction from children as the spiritual builders of human beings. Her concept of the prepared environment, including the prepared adult, supports this foundation for leadership and has applications beyond the classroom context. Leadership in the Montessori context has a biological base but incorporates elements of service and morality that guide social reform with a peaceful telos. While there are overlaps with existing models of leadership, this review suggests that a distinct perspective on leadership does begin to emerge from Dr. Montessori’s legacy.
The Montessori Approach as a Model of Personalized Instruction
Authors: Mavric Marusa
Published: November 2020

I present a brief overview of the key elements of personalized learning and Montessori education, a related pedagogical approach, aiming to examine common theoretical principles and key elements. I discuss the common features of personalized instruction and the Montessori approach of education. Both personalized instruction and the Montessori approach stand firmly on a constructivist paradigm and share many philosophical and theoretical principles. Research has shown that Montessori education is one of the most visible models that incorporates numerous aspects of personalized instruction and shares many common elements with personalized learning. This research has shown that, while personalized instruction also suggests many strategies for implementation of the concept, Montessori education actualizes the principles of personalized learning.
Bionformatics analysis reveals TSPAN1 as a candidate biomarker of progression and prognosis in pancreatic cancer
Authors: Ma Chenhui , Cui ZeLong , Wang YiChao , Zhang Lei , Wen JunYe , Guo HuaiBin , Li Na , Zhang WanXing
Published: November 2020

Pancreatic cancer (PCC) is a common malignant tumor of the digestive system that is resistant to traditional treatments and has an overall 5-year survival rate of less than 7%. Transcriptomics research provides reliable biomarkers for diagnosis, prognosis and clinical precision treatment, as well as the identification of molecular targets for the development of drugs to improve patient survival. We sought to identify new biomarkers for PCC by combining transcriptomics and clinical data with current knowledge regarding molecular mechanisms. Consequently, we employed weighted gene co-expression network analysis and differentially expressed gene analysis to evaluate genes that are co-expressed in tumor versus normal tissues using pancreatic adenocarcinoma data from The Cancer Genome Atlas and dataset GSE16515 from the Gene Expression Omnibus. Twenty-one overlapping genes were identified, with enrichment of key Gene Oncology and Kyoto Encyclopedia of Genes and Genomes pathways, including epidermal growth factor receptor signaling, cadherin, cell adhesion, ubiquinone and glycosphingolipid biosynthesis pathways, and retinol metabolism. Protein-protein interaction analysis highlighted 10 hub genes according to Maximal Clique Centrality. Univariate and multivariate COX analyses indicated that TSPAN1 serves as an independent prognostic factor for PCC patients. Survival analysis distinguished TSPAN1 as an independent prognostic factor among hub genes in PCC. Finally, immunohistochemical staining results suggested that the TSPAN1 protein levels in the Human Protein Atlas were significantly higher in tumor tissue than in normal tissue. Therefore, TSPAN1 may be involved in PCC development and act as a key biomarker for the diagnosis and prediction of PCC patient survival.
News Sentiment in Bankruptcy Prediction Models: Evidence from Russian Retail Companies
Authors: Makeeva Elena , Sinilshchikova Maria
Published: November 2020

This study is aimed at investigating the application of news sentiment analysis to bankruptcy prediction models in the context of the Russian retail sector.

We analyse 190 companies: 95 Russian retail companies that went bankrupt in 2015-2019, and 95 non-defaulting analogue companies. This figure was attained from a larger pool of 312 companies retrieved from the Spark database on the basis of analysis of relevant financial data and further validated by the presence of pertinent news media coverage within 3 years of default date. The methodological base of this analysis is the logistic regression approach, used as a benchmark model, and several machine learning models: random forest, support vector machine, and multilayer perceptron.

The predictor set applied consists of 34 financial variables and sentiment variables, aggregated using the ‘bag-of-words’ from a total sample of 4877 news articles, from more than 800 distinct online resource locations. We establish a set of hypotheses based on a review of existing literature in the area, and evaluate their accuracy on the basis of our technical analysis.

Our results show that sentiment variables are statistically significant, and that adding sentiment variables improves the performance of bankruptcy prediction models. Also, the results indicate some reference characteristics of companies in terms of word-choice and descriptions in the news, indicating word choices correlated with financially stability and those correlated with financially instability.

Published: November 2020

The genus Hydrocharis L. includes three geographically isolated species. Analysis of the actual data (32 thousand geographical locations and 1946 herbarium sheets) covering the period 1765–2019 made it possible to clarify the nature of the distri- bution of these species and its changes. Hydrocharis morsus-ranae L. has disjunctive Eurasian – North American temperate range, with a massive North American en- clave, the formation of which began in the 1930–1940s. The range of Hydrocharis dubia (Blume) Backer is disjunctive Southeast Asian – Australian subboreal-tropical, Australia enclave began forming in the 1850–1870s. Hydrocharis chevalieri (De Wild.) Dandy is a macrothermal Central African equatorial endemic. Current threat status of all species may be estimated as Least Concern. The mean annual temperature is the most contrasting feature of the distribution areas of the species, water depth, bottom soil type and hydrochemical composition have lower impact. Prognostic models of the potential distribution of the tagged species have been made.
Climate continentality increases the beta diversity of macrofungal communities
Authors:   Institute of Plant and Animal Ecology, Ural Branch RAS, Shiryaev Anton G.
Published: November 2020

The data on changes in the diversity of the model group of fungi of the middle boreal subzone in Eurasia are summarized. From Finland to Yakutia, with increasing climate continentality, the α- and γ-diversity of fungal communities decreases, but the β-diversity increases 1.7–5 times, which indicates an increase in the spatial isolation of local fungal communities. Similar trends have been found for other high-latitude regions: tundra and forest-tundra.

La sustentación del proyecto de tesis doctoral es una situación que genera estrés con múltiples manifestaciones físicas y comportamentales. En este artículo se analizó la respuesta autonómica de estrés en estudiantes de doctorado en una defensa de su proyecto de tesis doctoral. El estudio conto con una muestra de 16 estudiantes de doctorado, a quienes se les analizó la variabilidad de la Frecuencia Cardiaca en estado basal y en la defensa de su proyecto para evaluar su respuesta autonómica de estrés. Se evidencio que los estudiantes presentaron un aumento en la modulación autonómica simpática en la exposición a la defensa de su proyecto de tesis doctorado, debido a la disminución de los valores de Porcentaje de diferencias entre R-R adyacentes normales intervalos mayores de 50 ms (PNN50) = 15.2±13.7 y la dispersión longitudinal de los puntos, respectivamente, obtenidos a partir del gráfico de Poincaré (SD1) = 34.0±22.2 y SD2= 77.1±42.8 durante la defensa de su proyecto de tesis.  Podemos concluir que con base en los resultados obtenidos el incremento de la modulación simpática, por parte de los estudiantes de estudiantes de doctorado evidencia una baja capacidad adaptativa por parte de ellos a situaciones de alto nivel de estrés como sería la defensa de la propuesta de tesis doctoral, aspecto este que autores previos han relacionado con impedimentos en el rendimiento académico en estudiantes pregrado y posgrado pero que no están inmerso dentro de una actividad investigativa lo cual pone de manifiesto la necesidad de diseñar programas de regulación y entrenamiento del control y manejo del estrés en estudiantes de pregrado y posgrado. Esto permitirá mejorar los resultados académicos en contextos de educación superior como el evaluado en el presente trabajo.

It is a qualitative research of a deductive type and a semi-structured interview to collect the data and draw the pertinent conclusions. The results show a proportion of undergraduate students in very difficult socioeconomic situations, and with fear of being kidnapped when going to school, due to violent acts. Likewise, high school students have expressed their fear of being violated, which causes various psychological disorders. It was concluded that poverty and violent events harm inclusive and continuous education, school performance, collective well-being and the tranquility of students, and the general population
Cavell’s Importance for Philosophical Aesthetics
Authors: Stang Nicholas F.
Published: November 2020

Stanley Cavell was a prolific writer—the author of seventeen books and countless essays—and a famously stimulating teacher, but it would be impossible to convey in a short piece like this what made his writing and teaching inimitable. Instead, I will limit myself to trying to explain a bit of what I think is so important about Cavell’s work in aesthetics.
Thinking with Cavell about (His) Death
Authors: Ritter Eric
Published: November 2020

I am grateful to David LaRocca for inviting contributors to this special commemorative issue on the life and thought of Stanley Cavell. What follows is a brief philosophical reflection on what it means to think through the death of someone like Cavell, whose life and work continue to live on in so many respects and within so many people, as both this special issue and my experience in Stanley Cavell’s study bear witness to. I would argue that it is difficult to think through Cavell's death adequately (that is, to get the right sort of concepts in play). The cause of this difficulty is a productive tension within the extraordinary ordinariness of the concept of death itself: between the fact of cessation of biological life and the various respects in which Cavell has not ceased to exist, especially within the hearts and minds of so many. I aim in this piece to think with Cavell— that is, using tools he has provided—about (his own) death, thus performing the very productive tension which is the subject of the essay. I interweave some anecdotes from the past year spent working with the Cavell family to inventory and organize Cavell’s papers at the family’s home in Brookline, Massachusetts.

Background: Sputum smear negative pulmonary tuberculosis is a common problem faced by clinicians. Fiberoptic bronchoscopy may be very useful in diagnosing these cases which have no sputum or whose sputum smear is negative for acid fast bacilli. Objective of the current study was to assess the role of fiberoptic bronchoscopy in sputum smear negative under NTEP and radiologically suspected cases of pulmonary tuberculosis.Methods: Clinico-radiological suspected cases of pulmonary tuberculosis patients in whom two sputum smear for acid fast bacilli by Ziehl Neelsen stain under NTEP was negative were included in the study. Fiberoptic bronchoscopy was performed in all these patients and samples taken were sent for investigations.Results: Fiberoptic bronchoscopy was performed in 250 patients of suspected pulmonary tuberculosis whose sputum for AFB smear was negative. Cough was the most predominant symptom. Radiologically, right side disease was more common and upper zone was most commonly involved and infiltrates were common radiological finding. During bronchoscopy, congestion and hyperaemia (36%) and mucopurulent/mucoid secretions (32%) was seen in maximum number of cases. BAL was positive in 200 patients (80%), post bronchoscopy sputum was positive in 70 cases (28%) and biopsy was positive in 12 patients out of 16 performed biopsies (75%). The total TB positive cases after combining all the methods were 215 making the overall diagnostic yield of 86%.Conclusions: Fiberoptic bronchoscopy and post bronchoscopy sputum can be very useful for diagnosing sputum for AFB smear negative but clinico-radiological suspected cases of pulmonary tuberculosis patients.

Background: Ocular trauma is a major cause of visual impairment throughout the world, although little is known about the factors that affect the visual outcome in traumatic cataract in developing countries. The objective of the study was to find out the associated ocular injuries and the factors affecting final visual outcome of patients with traumatic cataract.Methods: This prospective-hospital based study was conducted on 50 patients of traumatic cataract in the department of ophthalmology government medical college, Ernakulam, from January 2009 to December 2011. Patients were managed with lens extraction and intraocular lens implantation. Regular follow up of patients was done and best corrected visual acuity (BCVA) and post-operative complications were assessed at the end of six months.Results: Our study showed that majority (64%) of patients were in the age group of <40 years with male preponderance. visual outcome was significantly better in younger age group (<20 years) than the older group (>20 years) (p=0.03). There was no significant difference in final visual outcome of traumatic cataracts caused by penetrating or blunt trauma (p=0.73). Corneal tear was most common associated ocular damage followed by uveitis, lens matter in anterior chamber.Conclusions: Age of the patient affects final visual outcome after surgical treatment of traumatic cataract but type of trauma (blunt/penetrating) had no significant effect on final visual outcome. Corneal tear was most common associated ocular damage.
Neutrophil-lymphocyte ratio and platelet-lymphocyte ratios correlate with staging in patients with colorectal carcinoma

Published: November 2020

Background: Systemic inflammation status is revealed to be associated with prognosis of solid tumours. Inflammatory markers including C-reactive protein, Neutrophil-lymphocyte ratio and platelet-lymphocyte ratio have been claimed to provide insight into resectability of carcinoma and in predicting prognosis. The objective of this study was to study neutrophil lymphocyte ratio and platelet lymphocyte ratio profiles in patients with colo-rectal cancers.Methods: This study was done as a hospital based descriptive on 80 patients diagnosed with colonic and rectal cancers. The study was carried out from May 2017 to May 2018 at General Surgery and Radiotherapy departments at Government Medical College, Trivandrum. Neutrophil lymphocyte ratio and platelet lymphocyte ratio was calculated and correlated with the pre-operative staging, post-operative staging and the histopathological grade.Results: Both neutrophil lymphocyte ratio and platelet lymphocyte ratio were found to be higher in patients with colo-rectal cancers as compared to values in normal healthy population. Neutrophil lymphocyte ratio was well correlated with tumour status, nodal status and overall stage in pathological staging. Platelet lymphocyte ratio was well correlated with tumour status and overall stage in CT staging and with tumour status, nodal status and overall stage in pathological staging.Conclusions: Neutrophil lymphocyte ratio and platelet lymphocyte ratio are correlated with colo-rectal carcinomas and may provide valuable information in staging the patients. They are cost-effective, easily measurable but affected by race, sex, age, co-morbidities and many other potential factors. Routine estimation of these ratios can serve as adjunct to staging as well as help to prognosticate the patients.
Is gender a determinant for the outcome of laparoscopic cholecystectomy?

Background: Currently, laparoscopic cholecystectomy is one of the most desirable procedures to treat symptomatic gallstone disease. Yet, various risk factors govern its conversion to open surgery. The impact of male sex as a risk factor for conversion has been a questionable issue.  The study aimed to evaluate the role of male sex on outcomes of laparoscopic cholecystectomy.Methods: As per inclusion and exclusion criteria, medical records of all the patients aged 18-70 years who underwent elective LC for a period of 14 months were accessed retrospectively. Data related to patients’ demographic details, intra-operative and post-operative findings was recorded and subjected to analysis.Results: Out of 232 selected cases, 17.67% were males and 82.32% were females. Mean age in both gender groups was similar (p=0.139). Body mass index was also found to be similar in both the groups (p=0.232). There was no significant difference (p=0.85) in the mean operative time between men (29.37±9.29) and women (28.88±15.66). Conversion to open surgery was seen only in female group (1.57%) but it is not significantly from the male group (p=0.42). No significant difference was observed in both groups regarding unwanted intra-operative events (p=0.231) and post-operative complications (p=0.70) and post- operative stay (p=0.50).Conclusions: This study suggests that male gender may not be considered as an independent risk factor for outcome of laparoscopic cholecystectomy. However, extensive research in future may cast further light on this issue.
Isolated lingual cysticerscosis: a rare case report

Taenia solium completes its life cycle in two hosts. Generally, cysticercosis results from accidental ingestion of the eggs of taenia solium through faeco‐oral contamination or autoinfection cysticercosis is commonly found in muscular and subcutaneous tissues. Central nervous system and eye are commonly affected. Despite abundant intermuscular tissue in oral cavity, it is uncommon site for cysticercosis because of high muscular activity and metabolic rate of oral tissues. We present a case of a 21-year-old male, presented with painless solitary swelling in the ventral aspect of tip of tongue at the centre. Excision of the swelling was done followed by histopathological examination. The histopathological examination revealed cysticercosis cellulosae in tongue musculature. Histopathological picture showed cysticercus larva surrounded by a double layered membrane. The patient was given albendazole 200 mg TDS for 30 days. One-year follow-up showed no signs of recurrence. Lingual cysticercosis usually presents as diagnostic dilemma. Complete excision along with histopathological examination is diagnostic. Infestation in this region is relatively mild as compared to ocular or neurocysticercosis. However, the patients should be examined thoroughly and followed up for possible concurrent ophthalmologic and neurologic involvements as well.  
Gender Disrupted During Storytime: Critical Literacy in Early Childhood
Authors: Burton Cayley
Published: November 2020

In Western early childhood education, cultural expectations about socially acceptable gender performance too often divide young learners along the Victorian sex-gender binary, erasing the beauty of childhood gender diversity. This essay advocates for the development of children’s gender literacy skills through the use of picture books. Building on Judith Butler’s theory of recognizability, I argue that gender is a sociocultural construct that can be actively disrupted during storytime activities. Texts featuring gender-nonconforming characters and corresponding pedagogical strategies for deconstructing gender portrayals in children’s literature are analyzed and offered in this essay.
