En los últimos 30 años, y como resultado de un vertebración entre diferentes disciplinas (entre las que podemos ubicar la antropología, la historia, la sociología, el arte, la psicología o la educación) se ha desarrollado un campo disciplinar que podemos denominar con la expresión anglosajona Body Studies. A partir del trabajo de algunos autores iniciales (Bryan Turner o David Le Breton) se han ido desarrollando diferentes aportaciones al estudio del cuerpo desde su perspectiva sociocultural. Nacidos como complemento o contrapartida a la perspectiva anatómica y biológica del cuerpo humano, han buscado ofrecer luz a determinados preguntas centrales sobre las formas de vivir la condición de humanidad. Distintos escenarios y geografías han jugado un papel relevante, pero de forma especial en los últimos 10 años han emergido grupos de investigación, proyectos, tesis, artículos, libros y congresos que sitúan a países como México, Brasil, Colombia o Argentina como uno de les ejes mundiales de la producción de saberes corporales. El número monográfico de la revista Albuquerque busca ofrecer a los lectores trabajos de actualidad centrados en la perspectiva de los Body Studies. Para el efecto, propone a investigadores, académicos e interesados en este campo (o intersección) un espacio en el cual debatir sus trabajos en la modalidad de proyectos finalizados de investigación (artículos completos), avances de proyectos, ensayos o artículos de revisión en los cuales se incorporen, problematizándose, temas que acerquen la perspectiva de los Body Studies desde diferentes ópticas, deslizamientos teóricos o metodologías.

Aricó y García Linera: prolegómenos a un estudio contrastado de la traducción del marxismo en América Latina
Authors: Patriglia Juan Pablo
Published: June 2020

El presente artículo realiza un primer acercamiento comparativo al marxismo de José María Aricó y de Álvaro García Linera. Las producciones escritas y la labor editorial de ambos intelectuales pueden entenderse como esfuerzos de traducción, en el sentido de Gramsci, del marxismo en América Latina. El punto de contacto que aquí interesa indagar refiere al trabajo de exhumación e interpretación de escritos inéditos de Marx que ambos emprenden para someter a crítica el marxismo canonizado como filosofía de la historia. En el marco de la crisis del marxismo, ello les va a permitir delinear un Marx adecuado a la realidad latinoamericana.

Authors: Gamboa Jerame , Gamboa Alberto G.
Published: June 2020

This study aims to describe the computer competency of high school teachers at Tinajero High School, in the Philippines, during the calendar year  2019. Specifically, it sought to identify and describe the teachers’ computer competency, strengths and weaknesses, and problems in MS Word, Excel, and PowerPoint. Most of the conducted studies focused on the computer competency of the students. Few studies addressed the computer competency level of the teachers. In this digital age, teachers are not exempted on learning he Microsoft application. Sooner or later, the world will be embracing a mode of instruction that uses more of computer than of those traditional ways.  This study used a descriptive-survey type of study and a validated competency test from Module quizzes from Innovate: A Mentor’s Guide to ICT Foundation Competencies by Microsoft Philippines. Findings showed the teachers are highly competent on MS Word, competent on MS Excel, and MS PowerPoint. Insufficiency of the computer equipment was identified as the main problem. It is therefore recommended to further strengthen the ICT capability training being given to the teachers so that technology will be maximized in making the educative system more impactful to the learners.
New tools of the influence of employers on the education and personnel training system in Russia
Authors: Chaplinsky S. I.
Published: June 2020

Providing rail transport with qualified personnel has traditionally been in the realm of close attention. Modern realities dictate the need to search for and implement effective tools for the interaction of the education system and employers, which can influence the training of personnel.

Thanks to the development of the national qualifications system in Russia, employers and the education system have received effective tools for interaction in the form of professional and public accreditation and independent qualifications assessment, which allow taking into account the requirements of employers, current trends and technologies of production organization, and assess willingness of students to perform specific labor functions in accordance with approved professional standards.

Rail transport has been actively involved in the implementation of elements of the national qualifications system, including professional and public accreditation and independent assessment of qualifications. The implementation of these measures should become an important mechanism in improving the professional level of railway workers and building an effective barrier for people who are not ready for responsible work in this area.

The considered tools of the national qualifications system contribute to the formation of responsible interaction of all stakeholders in the quality of learning outcomes.

Zakat is one of the pillars of Islam that is required for every people Muslim who is able, either male or female. Position zakat is very important in Islam case is indeed order by Allah SWT, and also many hadiths prophet explained about the obligation to zakat on property objects were in had. Need we understand together that the charity is worship that not only has the value of the relationship vertical, between humans by Allah, but the charity also has the value of the lives of human beings will be harmony, the rich will gain the satisfaction of the mind because it could help fellow Muslims who may be less capable, and that less capable of (poor) to utilize the wealth of zakat are accepted from those capable of (wealthy) who have issued their zakat. With the charity hopes the needs of the ummah who are less able to be fulfilled, including among others the alleviation of poverty. Zakat will run with good, effective, and precise target when property zakat in governance with management was good as well, especially in the era Hp at the moment is actually also adds convenience for the Muzakki to pay zakat on property and himself. History has proved that the implementation of the program of zakat which has been implemented by the institutions of zakat or carried out by the companions of the Prophet was actually able to alleviate poverty, help the person who is weak, even at times reign of Caliph Umar bin Abdul Aziz until no there are entitled to receive zakat because the entire population is already wealthy or already be Muzakki (people who tithe)

Authors: Bari Fazle , Ahmad Sajjad , Khan Hamzullah
Published: June 2020

Background: Nosocomial infections are major health issues in developing as well as developed countries. The objective of this study was to determine the frequency of MBL production in Pseudomnas aeruginosa that causes resistance to Imipenem and other ß-lactam antibiotics. Materials & Methods: A sample of 52 Imipenem resistant Pseudomnas aeruginosa colonizing or infecting the hospitalized patients were collected in Department of Pathology, Post Graduate Medical Institute, Lady Reading Hospital, Peshawar from June 2014 till May 2016. The organisms were identified by routine laboratory tests including biochemical methods and API NE System (Biomeriux) and the sensitivity pattern of commonly used antibiotics was established for each of these isolates using the disc diffusion method. Imipenem resistant strains were tested for MBL production by Imipenem-EDTA disc diffusion method. Results: The frequency of MBL activity was positive in 39 (75%) cases of Pseudomnas aeruginosa which encodes resistance to Imipenem and other ß-lactam antibiotics except monobactam. The sensitivity pattern of these antibiotics was as follows: piperacillin/ tazobactam 30.8%, amikacin and polymyxin B each 17.9%, tobramycin 12.8%, cefoperazone/ sulbactam and ceftazidime each 5.1%, ciprofloxacin, moxifloxacin, colistin sulphate, tetracycline, azithromycin and aztreonam each 2.6% and co-trimoxzole, gentamicin & rifampin each 0%. Conclusion: MBL production in P. aeruginosa confers a challenge for clinicians to treat such resistant infections with conventional antibiotics. Therefore testing each Imipenem resistant Pseudomnas aeruginosa for MBL production must be taken in routine consideration.
RECENT TECHNIQUES BASED ON THE UTILIZATION OF DNA AND AUTOSOMAL SINGLE NUCLEOTIDE POLYMORPHISMS FOR IDENTIFYING HUMANS
Authors: Khatoon Fahmida
Published: June 2020

The biological samples used in forensics can contain DNA which is highly fragmented as a consequence of exposure to any of the numerous degrading factors. Analysis of the sequence or size of the products of Polymerase chain reaction is at present responsible for the analysis of remains of humans in forensics. Despite the effectiveness of protocols based on PCR, there are certain limitations that are presented by the low numbers of copies of the template and the variations that are imposed by the decaying process to the template. The primary aim of this research is to explore the significance of autosomal SNPs in forensic science through the identification of humans at a crime scene. This study provides an exploration of the applicability of autosomal SNPs for the identification of humans at crime scene. This would fill the gap present in the current literature regarding the significance of autosomal SNPs in the identification of humans during crime scene investigation. It will also enable the identification of the criminals involved in several types of the crimes ranging from general theft to rape and sexual assault, murder, and robberies. It will also allow the identification of dead bodies in cases where it is difficult to identify the dead person due to unrecognizable condition of the body. This study will facilitate the improvement of the investigation of crime scene investigators. It will provide a significant way for the incorporation of recent techniques of the molecular genetics into forensics. Reduction in the workload of the crime scene investigators would also occur through the implementation of outcomes of this study into the field of forensic science. There are several studies which have demonstrated the applicability of SNPs in forensic investigations for identifying the humans at crime scene. Several effective and efficient technological systems have been developed by the researchers which are capable of performing analysis of biological samples containing degraded DNA because SNPs can be obtained from these samples. Physical characteristics of the individuals can be predicted through the analysis of SNPs. This can provide significant information about the color of eye, hair and skin of the individuals involved in crime.

Authors: Hayat Zafar , Ullah Inam , Hayat Khizar , Khan Hashimuddin Azam , Raziq Fazle , Khan Habibullah
Published: June 2020

Background: Falciparum malaria is a common disease in our area. Apart from its classical presentation, at times it may present with refractory anemia or pancytopenia. The aim of this study was to determine the refractory anemia and pancytopenia as complications of falciparum malaria and apart from peripheral blood smears the significance of rapid antigen tests and bone marrow examination in the diagnosis of falciparum malaria. Material & Methods: The descriptive study included 200 consecutive cases of fever and refractory anemia or pancytopenia from 2011 to 2014. Stratification of patients according to the clinical scenario included Group-A having fever with refractory anemia and Group-B with fever and pancytopenia. A detailed history, thorough clinical examination, and pertinent laboratory tests were performed. All patients were treated with antimalarial drugs and followed-up for eight weeks. The pre and post treatment hematologic parameters were compared. Results: Among the 200 patients, 85 were males and 115 females. The age ranged from 15 to 55 years. Stratification of patients on clinical scenario revealed 175(87.5%) patients with fever and refractory anemia (Group-A). Among these, 125(62.5%) patients were reported smear positive for P. falciparum. In the remaining 50 smear negative patients rapid antigen tests were performed and all were reported positive. In 25 patients of Group B with fever and pancytopenia, the peripheral smear for malaria was positive only in 5 patients. In the remaining 20 cases both the peripheral blood smears and rapid antigen tests were reported negative. Bone marrow examination was planned to confirm the bone marrow suppression as the cause of peripheral pancytopenia, to exclude leukemia and to identify P. falciparum. The bone marrow examination revealed P. falciparum in all these cases. All the patients had a dramatic response to treatment with antimalarials in terms of disappearance of fever and correction of anemia and bone marrow rescue with reversal of pancytopenia to normal counts. Conclusion: Plasmodium falciparum should be considered in all cases of prolonged fever with refractory anemia or pancytopenia in malaria endemic areas, even with negative smear and rapid antigen tests. Bone examination is mandatory for the diagnosis in such cases. There is dramatic response of such patients to treatment with antimalarial drugs and hematinics.

Abstract. Ammonia (NH3) emissions have large impacts on air quality and nitrogen deposition, influencing human health and the well-being of sensitive ecosystems. Large uncertainties exist in the bottom-up NH3 emission inventories due to limited source information and a historical lack of measurements, hindering the assessment of NH3-related environmental impacts. The increasing capability of satellites to measure NH3 abundance and the development of modeling tools enable us to better constrain NH3 emission estimates at high spatial resolution. In this study, we constrain the NH3 emission estimates from the widely used national emission inventory for 2011 (2011 NEI) in the U.S. using Infrared Atmospheric Sounding Interferometer NH3 column density measurements (IASI-NH3) gridded at a 36 km by 36 km horizontal resolution. With a hybrid inverse modeling approach, we use CMAQ and its multiphase adjoint model to optimize NH3 emission estimates in April, July, and October. Our optimized emission estimates suggest that the total NH3 emissions are biased low by 32 % in 2011 NEI in April with overestimation in Midwest and underestimation in the Southern States. In July and October, the estimates from NEI agree well with the optimized emission estimates, despite a low bias in hotspot regions. Evaluation of the inversion performance using independent observations shows reduced underestimation in simulated ambient NH3 concentration in all three months and reduced underestimation in NH4+ wet deposition in April. Implementing the optimized NH3 emission estimates improves the model performance in simulating PM2.5 concentration in the Midwest in April. The model results suggest that the estimated contribution of ammonium nitrate would be biased high in NEI-based assessments. The higher emission estimates in this study also imply a higher ecological impact of nitrogen deposition originating from NH3 emissions.

Abstract. We present a new and improved version (V4.0) of the NASA standard nitrogen dioxide (NO2) product from the Ozone Monitoring Instrument (OMI) on the Aura satellite. This version incorporates the most salient improvements for regional OMI NO2 products suggested by expert users, and enhances the NO2 data quality in several ways on a global scale through improvements to the air mass factors (AMFs) used in the retrieval algorithm. The algorithm is based on a conceptually new, geometry-dependent surface Lambertian equivalent reflectivity (GLER) operational product that is available on an OMI pixel basis. GLER is calculated using the vector linearized discrete ordinate radiative transfer (VLIDORT) model, which uses as input high resolution bidirectional reflectance distribution function (BRDF) information from NASA’s Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) instruments over land and the wind-dependent Cox–Munk wave-facet slope distribution over water, the latter with contribution from the water-leaving radiance. The GLER combined with consistently retrieved oxygen dimer (O2-O2) absorption-based cloud fractions and pressures provide high-quality data inputs to the new NO2 AMF scheme. The new AMFs increase the retrieved tropospheric NO2 by up to 50 % in highly polluted areas; these differences arise from both cloud and surface BRDF effects as well as biases between the new MODIS-based and previously used OMI-based climatological surface reflectance data sets. We quantitatively evaluate the new NO2 product using independent observations from ground-based and airborne instruments. The improved NO2 data record can be used for studies related to emissions and trends of nitrogen oxides (NOx) and co-emitted gases. The new V4.0 data and relevant explanatory documentation are publicly available from the NASA Goddard Earth Sciences Data and Information Services Center (https://disc.gsfc.nasa.gov/datasets/OMNO2_V003/summary/), and we encourage their use over previous versions of OMI NO2 products.
What millimeter-wavelength radar reflectivity reveals about snowfall: An information-centric analysis
Authors: Wood Norman B. , L'Ecuyer Tristan S.
Published: June 2020

Abstract. The ability of single-frequency, millimeter-wavelength radar reflectivity observations to provide useful constraints for retrieval of snow particle size distribution (PSD) parameters, snowfall rates, and snowfall accumulations is examined. An optimal estimation snowfall retrieval that allows analyses of retrieval uncertainties and information content is applied to observations of near-surface W-band reflectivities from multiple snowfall events during the 2006–2007 winter season in southern Ontario. Retrieved instantaneous snowfall rates generally have uncertainties greater than 100 %, but single-event and seasonal snow accumulations from the retrieval results match well with independent collocated measurements of accumulations. Absolute fractional differences are mainly below 30 % for individual events that have more substantial accumulations and, for the season, 12.6 %. Uncertainties in retrieved snowfall rates are driven mainly by uncertainties in the retrieved PSD parameters, followed by uncertainties in particle model parameters and, to a lesser extent, the uncertainties in the fallspeed model. Uncertainties attributable to assuming an exponential distribution are negligible. The results indicate that improvements to PSD and particle model a priori constraints provide the most impactful path forward for reducing uncertainties in retrieved snowfall rates. Information content analyses reveal that PSD slope is well-constrained by the retrieval. Given the sensitivity of PSD slope to microphysical transformations, the results show that such retrievals, when applied to radar reflectivity profiles, could provide information about microphysical transformations in the snowing column. The PSD intercept is less well constrained by the retrieval. While applied to near-surface radar observations in this study, the retrieval is applicable as well to radar observations aloft, such as those provided by profiling ground-based, airborne, and satellite-borne radars under lighter snowfall conditions when attenuation and multiple scattering can be neglected.
Timely estimates of India's annual and monthly fossil CO2 emissions
Authors: Andrew Robbie M.
Published: June 2020

Abstract. India is the world’s third-largest emitter of carbon dioxide and is developing rapidly. While India has pledged an emissions-intensity reduction as its contribution to the Paris Agreement, the country does not regularly report emissions statistics, making tracking progress difficult. Moreover, all global estimates of India’s emissions are for its financial year, not aligned to the calendar year used by almost all other countries. Here I compile monthly energy and industrial activity data allowing the production of estimates of India’s CO2 emissions by month and calendar year. Emissions show clear seasonal patterns, and the series allows the investigation of short-lived but highly significant events, such as the near-record monsoon in 2019 and the COVID-19 crisis in 2020. Data are available at https://doi.org/10.5281/zenodo.3894394 (Andrew, 2020).
Escribir con luz la mirada. Expresiones y metadiscursos de la fotografía-documento en el contexto contemporáneo español
Authors: Martín Núñez Marta
Published: June 2020

El presente artículo explora el uso de la luz en la fotografía no como un proceso técnico necesario, sino como un potente generador discursivo que escribe una mirada, un punto de vista sobre el mundo, al tiempo que reflexiona sobre el propio proceso. Confrontando las lógicas y los usos de la fotografía en distintos momentos históricos, podremos entender cómo ha ido cambiando la concepción de la luz bajo diferentes sensibilidades artísticas, que nos ayudarán a enmarcar tres proyectos contemporáneos a los que queremos prestar especial atención: Sputtering, de Jorge Isla (2017); Sol, de Ricardo Cases (2017) y C.E.N.S.U.R.A de Julián Barón (2011). Estos proyectos nos permitirán aproximarnos a tres fuentes de luz —fluorescente, solar y flash— y a tres formas de deconstruirla. En los tres proyectos la luz trasciende su mera función como posibilitadora de la imagen para enunciar la mirada autoral y metadiscursiva en el marco de la fotografía contemporánea española.
The Effect of Polarization on Economic Growth, Social Capital, and Democracy: A Cross-Country Study
Authors: Mehdi Maham Zahra , Siddiqui Danish Ahmed
Published: June 2020

In the last decade, one of the biggest global issues that have been debated upon is whether increased rates of migration, diversity, and political polarization stemming from these factors have any impact on the economic growth of countries. Accordingly, this paper explores the effect of polarization on democracy, social capital, education, and economic growth in a cross-country analysis involving developed countries, developing countries, and the least developed countries. A bilateral time series analysis was conducted by treating each country-set in isolation, as well as a group and focusing on the period 2009 to 2018. According to our results, polarization appears to have a negative effect on the economic growth of developing countries. The same results were observed when we analyzed all the countries collectively. An inverse relationship was also established between polarization and social capital in developed countries. Meanwhile, polarization does not have any significant impact on democracy and education for any of the countries under study. It was also determined that when treated independently, democracy, social capital, education, and GDP per capita all appear to have a varying yet negative effect on polarization.

Efficacy of the Bar Model Method of Teaching Mathematics to Year 7 Students: Case Study of Teachers in Brunei Darussalam
Authors: Matzin Ernie Sofinah , Mundia Lawrence
Published: June 2020

Mathematics is a subject that challenges many Brunei secondary school students. The Bar Method of instruction uses visual or pictorial representations to make mathematics easier to understand. The survey participants consisted of 127 randomly selected teachers (24 males and 103 females). Male teachers had significantly higher negative attitudes toward the BMM strategy than their female counterparts. The predictor variables that were significantly related to effective teaching of mathematics using the BMM included gender, age, Experience in using the BMM, Positive opinions on BMM, and district of residence. Evidence from the present study showed that the BMM was not much used by many school teachers. Only a small number or percentage of teachers used the BMM strategy when instructing students in mathematics most likely due to lack of skills and experience in using the method. However, both genders expressed the desire to use the BMM strategy in future, an indication of the degree to which the BMM is rapidly gaining popularity. Further large scale mixed-methods research employing interview probes was recommended to gain additional insights.

Published: June 2020

La primera versión del presente artículo fue presentada el 20 de febrero, antes que la Organización Mundial de la Salud (OMS) declarara al COVID 19 como pandemia mundial. Ello se destaca pues, el binomio “complejidad e incertidumbre” en el contexto de la emergencia sanitaria mundial muestra las graves falencias de la gestión pública salvadoreña, independientemente del Gobierno de turno, en ámbitos relevantes para el desarrollo humano.  Acá, se presenta una lectura de la gestión económica y del desarrollo, 1989-2019, la cual se caracteriza como un escenario de complejidad e incertidumbre para promover el bienestar, que no debe entenderse como inviabilidad de nación; pero sí, como un imperativo para un repensamiento de la gestión pública, desde el Gobierno Inteligente; para coadyuvar a la gestión del desarrollo en el país, al tiempo que se gestiona la complejidad e incertidumbre.

En los últimos años, la innovación tecnológica aplicada al aula permite apreciar un mayor uso de herramientas para mejorar los procesos de formación de los futuros profesionistas; sin embargo, ¿qué tanto pueden las TIC abonar al mejoramiento de las competencias sociales y humanistas? El presente artículo tiene por objetivo hacer una reflexión sobre el impacto de la realidad virtual en el desarrollo de las competencias transversales de reconocimiento y empatía, enfocándose en un tema concreto, la violencia de género. Para conseguirlo, se llevó a cabo un estudio e implementación en estudiantes de una universidad mexicana, logrando identificar diferencias significativas en el desarrollo final de estas competencias.
“ME CONTA QUAL É A DESSE CONTO”: A HISTÓRIA EM QUADRINHO NO ENSINO DE LÍNGUAS
Authors: Melo Livia Chaves
Published: June 2020

Situada na perspectiva indisciplinar da Linguística Aplicada, neste trabalho nosso propósito é discutir o dialogismo de Bakhtin, à luz da teoria de relações dialógicas e vozes verbais, a partir da análise de três personagens principais da História em Quadrinho (HQ) “Me conta qual é a desse conto” da Turma da Mônica. Apresentar ainda uma proposta de atividade didática para aulas de línguas na Educação Básica com base na HQ selecionada. A perspectiva dialógica bakhtiniana é utilizada como principal aporte teórico-metodológico. A análise é de natureza descritivo interpretativa e segue uma abordagem essencialmente qualitativa. Mostramos que o uso de HQ como material pedagógico em contextos de instrução é bastante proveitoso não só por sua ludicidade, mas por seus recursos multimodais, que facilitam e instigam à leitura, estudo dos conteúdos curriculares e à produção escrita.
The Influential Factors on Capital Structure: A Study on Portuguese High Technology and Medium-High Technology Small and Medium-Sized Enterprises
Authors: Tong Yehui , Serrasqueiro Zelia
Published: June 2020

Using the panel data model, this paper studies the influential factors on the capital structure of small and medium-sized enterprises (SMEs) in high and medium-high technology manufacturing sectors in Portugal. In particular, the total sample is further classified into young SME group and mature SME group for observing the similarities and differences. The research results show that firm size, profitability, firm age, and industry sector impact much on the capital structure and debt ratios; on the other hand, the impacts of tangible assets, intangible assets, and growth are not as strong as the previous factors. The differences of the impacts on young and mature SMEs are mainly shown by growth, intangible assets and industry sector. In particular, intangible assets show more statistical significance in young SMEs compared to mature SMEs, and intangible assets tend to be positively related to long-term debt especially in young SME group; this may reflect the positive attitude of financial institutions on the value of intangibles in generating future benefits for high and medium-high technology young firms. Besides, the findings tend to support the pecking order theory more than the trade-off theory regarding the high and medium-high technology manufacturing SMEs here.

Authors: Xu Chuangqiang , Feng Qingxiang
Published: June 2020

Business operation and the construction work of the Communist Party of China (hereinafter referred to as the Party or CPC) are organically connected for state-owned commercial banks. It’s of great importance and value for transformation and progress of the sate-owned commercial banks to improve the liaison mechanism for party construction of the state-owned commercial banks, facilitate efficient interaction among the party organizations at all levels of the state-owned commercial banks and good communication among the party members, break the information isolated island among the party organizations at all levels of the state-owned commercial banks, and establish a convenient and fast communication network. Thus, an interlinking mechanism for party construction of the state-owned commercial banks should be built. Measures should be taken to build closer relationship between the Party and the masses, between the cadres and the masses; and further improve the humanistic care mechanism of the party organizations of the state-owned commercial banks.
Cash Crops and Food Security: A Case of Tea Farmers in Burundi
Authors: Bitama Pierre C. , Lebailly Philippe , Ndimanya Patrice , Burny Philippe
Published: June 2020

Food security is a genuine challenge in developing countries. To combat food insecurity, various means and strategies are being mobilized. The promotion of cash crops in rural areas is one of the main strategies for improving food security. Accessibility to subsistence staples and stable living conditions for rural farmers are made possible by the relatively high and permanent income from cash crops. This paper addresses the issue of food security by discussing the power of tea crop incomes in a rural tea farming area in Burundi. A survey was conducted in 2019 among 120 smallholder tea farmers in two communes located in the Mugamba natural region of Burundi. The results show that the tea plant contributes significantly to food security for both tea farmers and non-tea farmers. By complementing other livelihood resources, tea incomes improve the food security of smallholder tea farmers. In addition, tea incomes ensure the resilience of smallholder tea farmers during lean seasons and against various shocks. Besides, the perennial nature of the tea plant provides a pension for smallholder tea farmers in their old age.

Integrating Radiology into an AI System for Physician Decision Making
Authors: Paruchuri Venkata A. , Granville Bobby C.
Published: June 2020

Over time, physicians gather a vast amount of data such as radiographic images, medical procedures, treatments, and insurance coverage about the patients. A Case-Based Reasoning (CBR) system is developed to organize and retrieve such data to aid physicians in making a diagnosis and formulating a treatment plan for patients with similar traits. This research is an extension of the earlier work presented by the authors. Our earlier research did not consider radiographic images, although radiology plays a vital role in diagnosing and treating patients. Currently, a new algorithm is created to retrieve and organize information from the CBR system to add radiographic images to the patient’s case data. This system is tested and the performance results prove that the acceptance rate achieved by this system is higher than that of the earlier system.
Study of Anticancer Activity of Pratensein and Pratensein Glycoside Isolated from Cuscuta kotchiana
Authors: Behbahani Mandana , Moghaddam Mohaddeseh
Published: June 2020

In the present paper, we demonstrate that extract of Cuscuta kotchiana is able to inhibit in vitro proliferation of two human breast cancer cell lines, MCF-7 and MDA-MB-231. The expression levels of p53, bcl-2, caspase-3 and bax genes at the mRNA and protein levels were evaluated using quantitative Real Time PCR and western blot analysis. The most active fractions of C. kotchiana were detected by NMR as pratensein and pratensein glycoside. The cytotoxic activity of pratensein glycoside was significantly more than pratensein. The expression level of bcl2 gene was decreased in cancer cells treated by both compounds at CC50 concentrations. But the expression levels of caspase-3, p53 and bax genes were increased in treated cancer cells. In conclusion, all the data demonstrated that the glycoside form of pratensein is important agent in inducing apoptosis in human breast cancer cells.

De reikwijdte van de term ‘opzettelijk’ in artikel 2 lid 1 Wet op de economische delicten

In een arrest van september 2019 koppelt het Hof Arnhem de ‘wist-variant’ van de ten laste gelegde gevaarzetting aan de vraag of sprake is van opzettelijke overtreding van artikel 32 Arbeidsomstandighedenwet. Het hof spreekt vrij van die wetenschap en tegelijk daarmee ook van opzettelijke overtreding van artikel 32 Arbeidsomstandighedenwet. Vervolgens wordt slechts de overtredingsvariant bewezen geacht. In deze bijdrage zal worden uiteengezet waarom het hof hiermee de systematiek die ten grondslag ligt aan de Wet op de economische delicten (WED) miskent.

Naschrift bij ‘Het belang van privacy in het strafrecht’

De openbaarheid van rechtspraak is een fundamentele pijler van de democratische rechtsstaat. Daar staat tegenover dat een verdachte of veroordeelde grote waarde hecht aan anonimiteit in het strafproces. Gerechten dienen bij de publicatie van strafrechtelijke informatie deze anonimiteit te waarborgen. Maar hoe is het toezicht hierop geregeld? Wat gebeurt er als bij het beschikbaar stellen van informatie over gerechtelijke (straf)zaken de Algemene verordening gegevensbescherming of de Wet justitiële en strafvorderlijke gegevens wordt geschonden? Is de Autoriteit Persoonsgegevens bevoegd een boete op te leggen? In dit naschrijft bij het artikel ‘Het belang van privacy in het strafrecht’ worden deze vragen beantwoord.
