MODELING FOR THE APPLICATION OF ANALYTIC SIGNALS OF MAGNETIC GRADIENT TENSOR TO DETERMINE BOUNDARIES OF SOURCE
Authors: Pham Thanh Luan
Published: January 2018

The analytic signals of the magnetic tensor gradient within two-and three-dimensional space can be applied as a useful tool to estimate the depth and position sources because its value characteristics only depend on location but magnetization direction of the sources of the magnetic anomaly [7]. In this paper, we present results of the study for application of the combination of derivatives of directional analytic signals of the magnetic tensor gradient to determine the edges of the sources through the new function Edge-detector (|ED|). Algorithms and programs written in the Matlab language have been used for test calculation on 3D models in correlative comparison with the method using the amplitude function of analytic signals ([2]). The calculation results showed the advantages of the new function |ED| and its applicability in determing the boundaries of sources of magnetic anomaly.

Published: January 2018

This study was carried out to determine the frequency of lethality, Mutagenic frequency, effectiveness and efficiency induced by ethyl methane sulphonate (EMS) and sodium azide on foxtail millet. The seeds were treated with different concentrations of EMS and sodium azide. Number of morphological mutant were observed visually and recorded. Mutagenic frequency, effectiveness and efficiency were highest for EMS at 0.1% concentration (Mutagenic frequency 7.50% effectiveness 18.75% and efficiency 7.50%) and sodium azide at 0.2% concentration (Mutagenic frequency 7.00%, effectiveness 1.84% and efficiency 1%). Lower concentrations of EMS and sodium azide were more effective and efficient in inducing mutation with low biological damages and high mutation frequency. EMS was more effective and efficient in inducing variability in foxtail millet than sodium azide. Therefore, mutants foxtail millet with low biological damages and high mutation frequency can be developed at low concentration of EMS and sodium azide for breeding of foxtail millet.

Authors: Desai Parth N , Del Rosso James Q , Lebwohl Mark G
Published: January 2018

Psoriasis is a chronic, inflammatory disease with a diverse array of clinical manifestations involving the skin, joints, and nails. Of these, nail psoriasis is a frequently overlooked, yet important complication of psoriasis which can cause significant physical and psychological distress to a patient. Psoriasis affecting the nail unit can pose both diagnostic and therapeutic challenges to physicians due to its clinical heterogeneity, the multitude of available treatment options, and the general lack of high-quality research on the subject. In order to aid the practicing clinician in appropriate diagnosis and treatment of nail psoriasis, this review provides an overview of the epidemiological, clinical, and pathophysiologic features of the disease, while also attempting to develop a rationale for effective medical management of the condition.

Published: January 2018

Vibrational sum-frequency generation (vSFG) spectroscopy is used to determine the molecular structure of water at the interface of palmitic acid monolayers. Both measured and calculated spectra display speci�c features due to third-order contributions to the vSFG response which are associated with �nite interfacial electric potentials. We demonstrate that theoretical modeling enables to separate the third-order contributions, thus allowing for a systematic analysis of the strictly surface-sensitive, second-order component of the vSFG response. This study provides fundamental, molecular-level insights into the interfacial structure of water in a neutral surfactant system with relevance to single layer bio-membranes and environmentally relevant sea-spray aerosols. These results emphasize the key role that computer simulations can play in interpreting vSFG spectra and revealing microscopic details of water at complex interfaces, which can be difficult to extract from experiments due to the mixing of second-order, surface-sensitive and third-order, bulk-dependent contributions to the vSFG response.

Published: January 2018

The need for energy-saving materials is pressing. This paper reports on the design of energy-saving glasses and films based on plasmonic composite glasses is nontrivial and requires to take full advantage of both materials and shape-related properties of the nanoparticles. We compute the performance of solar plasmonic glasses incorporating a transparent matrix and specially-shaped nanocrystals. Plasmonic nanoshells are shown to exhibit the best performances as compared to nanorods and nanocups. Simultaneously, the synthesis of plasmonic nanoshells is technologically feasible using gas-phase fabrication methods. The computational work was done for noble metals (Au, Ag) as well as for alternative plasmonic materials (Al, Cu, TiN). Inexpensive materials (Ag, Al, Cu, TiN) show overall good performance in terms of the commonly-used figures of merit of industrial glass windows. Together with numerical data for specific materials, this study includes a set of general rules for designing efficient plasmonic IR-blocking media. The plasmonic glasses proposed herein are good candidates for cheap optical media to be used in energy-saving windows in warm climates' housing or temperature-sensitive infrastructure.

Authors: Kotsopoulos Donna , Zambrzycka Joanna , Makosz Samantha
Published: January 2018

Visual-spatial ability is important for mathematics learning but also for future STEMparticipation. Some studies report children with dyslexia have superior visual-spatial skills andother studies report a deficit. We sought to further explore the relationship between childrenformally identified as having dyslexia and visual-spatial ability. Despite our best efforts, anddespite recruiting from a large potential sample population, we were unable to secure asufficient amount of participants for statistical power. Thus, our findings consider the ethicaldilemma of diagnosis; namely, (1) how do children come to be tested for disabilities? And, (2)what are the potential implications, mathematical or otherwise, for children who havedisabilities but are not formally identified? This report has important implications for childrenwith disabilities and for educators.
Making Visible and Acting on Issues of Racism and Racialization in School Mathematics
Authors: Morvan Jhonel A.
Published: January 2018

Schools, as social systems, may knowingly or unintentionally perpetuate inequities through unchallenged oppressive systems. This paper focuses on mathematics as a subject area in school practices in which inequities seem to be considered normal. Issues of racism and racialization in the discipline of mathematics are predominantly lived through the practice of streaming where students are enrolled in courses of different levels of difficulty. Such practice denies marginalized groups of students the full benefit of rich learning experiences. These issues should be of concern for activists, advocates, and allies as well as individuals and groups who are systematically and directly affected. The purpose of this paper is to make visible issues of racism and racialization in school mathematics to a range of stakeholders that include: school administrators, teachers, students, parents, education advocates, academics, educational researchers, and politicians. The ultimate goal is that the knowledge gained through this call to action will contribute toward eliminating social injustice in all school systems, particularly as it relates to skin colour, country of origin, culture, language, customs, and religion.
Feminist Scholar-Activism Goes Global: Experiences of “Sociologists for Women in Society” at the UN
Authors: Jauk Daniela
Published: January 2018

This article focuses on the experiences and strategies of members of Sociologists for Women in Society (SWS) who strive to bridge the worlds of social activism and academia. It concerns the International Committee’s work at the United Nations (UN), specifically at the annual Commission on the Status of Women (CSW) meeting. It builds on transnational feminist literature that has discussed the UN as stage for a diverse global women’s movement and provider of global gender equality norms that, if utilized, advance gender equality in its member states. I analyze themes that emerged from a sample of in-depth interviews with current or former UN scholar-activists within SWS from a larger ethnographic study, and present experiences and challenges of SWS members’ engagement with UN politics and policy development since the mid-nineties. I demonstrate that SWS does justice to its mission of serving as an activist organization through its work in the global arena. Analysis of interviews, observations, and archival material demonstrates that SWS’s UN scholar- activism is increasing the visibility and applicability of feminist sociology. While this activism critically examines the discourse, it also disrupts hegemonic discourse and offers opportunities for concrete social change, particularly through linking activism, mentoring, and teaching.

Este texto procura refletir sobre a participação de duas estudantes de Pedagogia em uma Comunidade de Prática (CoP) em que os membros compartilham experiências e percepções, com a finalidade de aprender Matemática e aprimorar a prática docente. Considera-se que a vivência em um espaço de diálogo e reflexão, como uma CoP, pode proporcionar aprendizados docentes conjuntos. A CoP foi composta por estudantes de Pedagogia e de Licenciatura em Matemática e por professores do ensino fundamental, anos iniciais e anos finais, que ensinam Matemática, além de pesquisadores do ensino superior e estava vinculada a um projeto aprovado no Programa Observatório da Educação (OBEDUC). Havia o desafio de criar um ambiente em que todos interagissem e participassem ativamente dos empreendimentos. Os encontros foram gravados e transcritos e foram utilizados, também, documentos escritos pelos participantes. Como resultado, percebeu-se que o envolvimento do futuro professor em empreendimentos da CoP interferiu diretamente em sua formação docente. Uma das questões que ficou evidente na reflexão acerca das atividades desenvolvidas na CoP do OBEDUC investigada é que a aprendizagem docente das estudantes de Pedagogia ficou potencializada devido ao sentimento de pertença gerado pela participação e envolvimento nos empreendimentos da CoP.

Authors: Ribeiro Rogério Marques , Powell Arthur Belford
Published: January 2018

Apresentamos, neste artigo, algumas reflexões acerca de uma pesquisa que buscou, por meio de uma interlocução entre a Modelagem Matemática e as discussões sobre o conhecimento profissional do professor, problematizar o uso de representações matemáticas pelos professores que ensinam matemática nos anos iniciais. A produção de dados foi realizada a partir da observação dos encontros de uma formação continuada para professores que atuam nesse nível de ensino. Destacamos, assim, que essa investigação está alicerçada pelos princípios da pesquisa-ação, tendo as gravações em áudio e vídeo dos encontros, além do uso de questionários e entrevistas com os participantes, como principais instrumentos utilizados para a coleta de dados. Para a análise desses dados utilizamos o método da análise de conteúdo, e os resultados dessa análise nos permitiram considerar que a Modelagem Matemática, na formação continuada de professores, contribuiu não apenas para discutir o conhecimento matemático para o ensino mobilizado por eles, mas também possibilitou que compreendêssemos como esses professores reconhecem os problemas que envolvem  conteúdos matemáticos e suas representações. Esses resultados apresentam, ainda, evidências de que uma formação continuada sob a ótica da Modelagem Matemática contribui para o conhecimento matemático para o ensino.

Attention Deficit Hyperactivity Disorder (ADHD)- a matter of concern
Authors: Mirza Maria
Published: January 2018

Attention deficit hyperactivity disorder (ADHD), a serious neurodevelopmental disorder that is associated with deterioration in various domains of major life activities. However, various exceptional cases with the disorder may be observed functioning well in some areas of life (e.g., Michael Phelps and swimming, Ty Pennington and destroying and rebuilding houses, Glenn Beck and political commentary, etc.), they probably have conflicts with other areas of functioning (DWIs, managing money, social relationships, etc.) But even if well-altered, these exceptional success stories do not represent the more typical reactions of children with ADHD followed to adulthood. It is one of the most difficult diagnoses to classify as evident from changing definition norm observed in the revisions of Diagnostic and statistical manual (APA 1980, APA 1987, APA 1994). ADHD is reportedly the most pervasive disorder of childhood influencing approximately 3% to 5% of school-aged children with prevalence rates increasing significantly over the past two decades. Children with ADHD struggle with symptoms of inattention, hyperactivity, or impulsivity above and beyond what is developmentally appropriate. ADHA is diagnosed in childhood, most of the children diagnosed with ADHD exhibit symptoms that persist into adolescence and adulthood.

Published: January 2018

Background: Till the 70's, it was believed that depression among students was rare or even non-existent. This concept has now begun to change. Research studies that show presence of depressive problems in students have started surfacing but much more need to be explored. Objective: To find out the causes and level of stress and depression among undergraduate medical students of public sector medical universities and medical colleges of Sindh. Methods: This cross sectional psycho-social analysis included 587 undergraduate medical students from 6 public sector medical institutes of Sindh. Multistage sampling was implemented. Sampling procedure includes both stratified sampling and simple random sampling. Stratification was done on the basis of location of university and medical college and year of study. Informed consent was taken from every student. Stress and depression levels were measured in accordance to academic and non-academic stressors. Data analysis was done on SPSS version 17.0. Results: Girls showed a much higher depression score in comparison with boys. Hostilities had a significantly greater depression score than those who were living with their families. It was revealed that students having higher grades and GPA had much higher scores of depression compared to students having lower grades and GPA. Fear of unemployment after studies and lack of positive response from parents and institution were few of the most potent stressors. Conclusion: On the basis of our result we conclude that a decrease in medical syllabus and time extension in semesters may directly reduce students’ workload and consequently decrease the depression level. Stress management programs should be conducted in every institute for coping with the stress. Efficacious moral and substantial support from faculty, teachers and families is crucial to ameliorate of students’ health.
Physical, Emotional and Catastrophizing Upshots of Chronic Pain the Study On Pain Stress
Authors: Naseem Uzma , Ahmed Sadaf , Noushad Shamoon
Published: January 2018

There are original physical basis of pain, even when an anatomical site or pathophysiological basis cannot be established, but pain also recognizes the importance of affective, cognitive, behavioral, and social factors as contributors to chronic illness behavior. It is also linked with Catastrophizing in relation with sufferer’s threshold of pain intensity, pain related disability and psychological distress are found to be significantly high regardless of any type of pain. Unlike acute nociceptive pain chronic pain is not self-limiting and usually neurological in origin, it may evolve in the damaging of either central nervous system or peripheral nervous system results into anxiety, fear, depression, sleeplessness and lack of social interaction so there is a self-perception of stress. In this study Stress has been taken as an amplified condition of psychological effects which is being induced by chronic pain. Aim of the present study was to highlight the presence of physical and emotional constraint relative to other related stresses like traumatic, nutritional and mental stress among chronic pain survivor both by observing the ability and intensity to catastrophize. In a cross sectional study, 140 individuals have been enrolled from general population who have been suffering from any type of chronic pain with exception of Menopausal women, Cardiovascular diseases, Nephropathy and cancer, and age between 18 to 50 years. For evaluation multistage random selection procedure have been performed by governing questionnaire to examine their pain duration, intensity, frequency, and degree of multi psychological feeling using PCS of Michael JL Sullivan and stress by SSS. It is concluded that sufferers rise to the challenge of difficult painful situations that leads to a number of psychophysiological disorders and raised emotional distress, especially depressive symptoms, these are often poorly controlled. On the basis of the available evidence that it is not clear whether chronic pain sufferers really do have higher levels of distress compared to others it is recommended that ability of being catastrophize as well as emotional and physical distress can be improved by various relaxation and counselling therapies that can relieve the cycle of pain.

George Herbert Mead: sobre el gesto como inicio de la interacción social y el desarrollo de las interacciones sociales saludables
Authors: García Meraz M.
Published: January 2018

El trabajo explora, de manera general, algunas de las tesis que relacionan el gesto y la acción social a través de la teoría de George Herbert Mead. Los conceptos de acción social, gesto, el otro generalizado y la comprensión toman una importancia relevante en el debate relacionado con la interacción social. La exposición comienza con un ejemplo de una interacción en la vida cotidiana: ¿Qué patrones sociales y culturales interfieren en la comprensión de este tipo de interacción? ¿Cómo podemos "leer" las intenciones de comportamiento de los otros, incluso a través de los gestos y sin el lenguaje formal? Para Mead, la respuesta está en el carácter simbólico de los gestos y cómo éstos pueden indicarnos algo más que sólo emociones, por ello, son el comienzo de la interacción social. Pero lo más importante es que los gestos —como parte de la comunicación simbólica— son anteriores al lenguaje formal. En estas líneas de argumentación, incluso el pensamiento es social y tiene su origen en el mundo social. Estos argumentos le permiten ir más allá de postulados mentalistas y la filosofía de la conciencia y seguir una tesis sociocultural de interacción social.
La salud de los ejecutivos. Una propuesta de atención
Authors: Díaz-Pérez LE , Barrera-Gálvez R.
Published: January 2018

El presente trabajo corresponde a una alternativa para mejorar el desempeño de los equipos directivos, basado en la atención a la salud en diferentes campos: físico, mental, emocional, espiritual y gerencial. El diseño de esta propuesta, considera al personal directivo de una organización dentro de un macrosistema social, con gran capacidad de transformación y alto desempeño; y a sus directivos como un elemento estratégico. La salud se conceptualiza como la condición de bienestar, que permite el desarrollo del potencial humano, indispensable para la salud de una organización; y corresponde al medio para lograr su máximo desempeño en el cumplimiento de su misión. Los programas de salud pública, no incorporan acciones de salud para directivos (grupo de riesgo específico); este trabajo promueve un programa de salud integral, preventivo y de bienestar; a diferencia de la oferta de servicios existente, y que es parcial y restaurador. Las condiciones de salud no sólo representan la posibilidad de vivir diversas experiencias gratificantes, también son altamente rentables para la organización.
