Concession and reassertion: on a dialogic discourse pattern in conversation
Authors: Lindström Jan K. , Londen Anne-Marie
Published: February 2017

This is a study of a concessive discourse pattern in which the speaker first makes an assertion, then backs down from it, and eventually recycles the original standpoint. This practice bears a strong resemblance to show concessions which Antaki and Wetherell (1999) identify as typical of ideological debate. Our data are from Swedish conversations in everyday as well as institutional settings. We argue thus that the practice of conceding and reasserting does not limit itself to specific rhetoric purposes but is a generally available device for reasoning and argumentation in conversation. The practice enhances intersubjectivity in interaction by acknowledging other viewpoints, signaling reciprocity between the participants, and contributing to preference for agreement. We account for the dialogic nature of this concessive pattern by analyzing first same-speaker produced and then other-induced concessions. We also consider the relation of the concession–reassertion format to other concessive practices.
Research paper. Distribution, Abundance and Dominance of Three Brachinus Species (Coleoptera: Carabidae) in Seven Agricultural Crops in Romania, within the Period 1977–2010
Authors: Varvara Mircea
Published: February 2017

The present paper is a relevant synthesis of collecting original data on the occurrence, quantitative representation and autecological data of three species of the genus Brachinus: B. crepitans Linnaeus, 1758, B. psophia Audinet-Serville, 1828 and B. explodens Duftschmid, 1812 from seven agricultural crops during 19 growing seasons 1977-2010 (wheat, sugar beet, apple orchards, sunflower, maize, potatoes, vineyards). The beetles were pitfall-trapped using predominantly 12 Barber pitfalls in each site, protected against precipitation. 945 specimens of Brachinus crepitans, 431 specimens of B. psophia and 175 specimens of B. explodens were collected.
Modelo Explicativo del Desempeño Académico desde la Autoeficacia y los Problemas de Conducta
Authors: Castellanos Páez Virgelina , Latorre Velásquez Diana Carolina , Mateus Gómez Sandra Milena , Navarro Roldán Claudia Patricia
Published: February 2017

Se analizó un modelo explicativo del desempeño académico para conocer si los problemas de atención median la relación entre la autoeficacia académica y el desempeño académico, y si la ansiedad y la depresión moderan dicha relación. Participaron 326 estudiantes (11-18 años), quienes diligenciaron el Youth Self-Report (Achenback & Rescorla, 2001) y la escala de autoeficacia de Aguilar, Valencia y Martínez (2001). El desempeño académico se obtuvo del promedio de calificaciones de dos bimestres académicos en lenguaje, ciencias y matemáticas. El análisis de regresión mostró que los problemas de atención median la relación entre la autoeficacia, explicando el 40% de la varianza. La variable ansiedad-depresión moderó esta misma relación evidenciando que, a mayores niveles de ansiedad y de depresión, menor autoeficacia académica y menor desempeño académico. En suma, la relación entre la autoeficacia académica y el desempeño académico fue afectada por los problemas de conducta.

Authors: Sepehri Mehdi , Ildoromi Ali Reza , Malekinezhad Hossein , Hosseini Seyed Zeynalabedin , Talebi Ali , Goodarzi Saba
Published: February 2017

Flood hazard (FH) can be considered as one of the most serious threats mainly in areas and countries where other natural hazards hardly occur. This paper presents a simple approach to urban FH assessment in regions where the primary data are scarce. The objective of this study is to develop a geographic information system-aided urban FH zoning of the study area (in Iran), by applying multicriteria decision analysis and fuzzy analysis. In this process, the research methodology focused on the analysis of the variables controlling water routing. The model incorporated four parameters: distance to the drainage channels, topography (topographic wetness index), infiltration and cover type. The results demonstrated that most floods occur near the discharge channels and in the lower parts of the study area.
Disaster Risk and Asset Returns: An International Perspective
Authors: Liu Edith X. , Lewis Karen K.
Published: February 2017

Recent studies have shown that disaster risk can generate asset return moments similar to those observed in the U.S. data. However, these studies have ignored the cross-country asset pricing implications of the disaster risk model. This paper shows that standard U.S.-based disaster risk model assumptions found in the literature lead to counterfactual international asset pricing implications. Given consumption pricing moments, disaster risk cannot explain the range of equity premia and government bill rates nor the high degree of equity return correlation found in the data. Moreover, the independence of disasters presumed in some studies generates counterfactually low cross-country correlations in equity markets. Alternatively, if disasters are all shared, the model generates correlations that are excessively high. We show that common and idiosyncratic components of disaster risk are needed to explain the pattern in consumption and equity co-movements.

Authors: Nagaral Girish V. , . Karibasappa
Published: February 2017

Background: Vitiligo is considered to be symptom less and its presentation is boundless varying from isolated focal lesion to bizarre generalized lesions. The present study was undertaken to study the histopathological changes in lesions of vitiligo in south Indian population.

Methods: 150 patients with mild to moderate vitiligo features attending the outpatient department of Dermatology, Venereology and Leprology at Chitageri General Hospital and Bapuji Hospital attached to J.J.M Medical College, Davengere were utilized to study the histopathological features in vitiligo and its association with other diseases.

Results: Destruction of melanocytes at dermo-epidermal junction was noted. We have observed presence of melanocytes in the basal layer of the epidermis on left side of the lesion, whereas decreased melanocytes in the basal layer of the epidermis on the right side of the same lesion in the present study. Dermis with mild perivascular lymphocytic infiltration and acanthosis along with mono nuclear cell infiltration in the upper dermis was observed.

Conclusions: The present study gives better knowledge to the clinicians about the lesions of vitiligo and its pathogenesis.

Authors: Chacko Eby , Vellaisamy Seethalakshmi Ganga , Gopalan Kannan , Nanjappachetty Govindarajan
Published: February 2017

 Introduction: Polymorphic light eruption (PMLE) is an acquired photodermatosis characterized by a polymorphic eruption ranging from papulovesicular lesions to large plaques. The prevalence of PMLE varies from 5% to 15% in various studies across the world and in India it is 0.56%.

Objective: The present study was conducted to study the clinical pattern and to assess the epidemiological aspects of polymorphic light eruption.

Material and Method: A cross sectional prospective study was conducted in Dermatology OPD between April 2015 and June 2016. A total of 100 patients with symptoms and signs of PMLE were included in the study. Data were coded and analyzed.

Results: Majority of the cases in our study were in the age group of 21 - 30 years (36%). It was more common in females (82%) when compared with males (18%). Occupation of most of the patients (29%) was farmers in our study population. Positive family history of PMLE was seen in 11% of the study population. The commonest form was the papular type (46%) and the second most common type was plaque type (17%). Regarding the distribution of lesions, about  51%  of  our study subjects had polymorphic lesions confined to only one area of their body mostly forearm (25%) followed by face (12%).

Conclusion: The prevalence of PMLE was 1.34% in our study population. Pruritus was the presenting complaint in most of the cases and the rash was mainly seen in areas exposed to sunlight.

Background: Various cutaneous manifestations are common in the neonatal period. Transient and pathological neonatal dermatoses should be differentiated to avoid unnecessary treatment and to relieve parent’s stress. The present study is being carried out to study the clinical pattern of cutaneous lesion during the neonatal period, to determine the frequency of various dermatoses i.e. physiological and pathological lesions in neonate along with appropriate management of cases.

Methods: A total of 100 neonates from labour rooms and pediatric nursery of Basaveshwara general hospital, Kalaburagi were evaluated for cutaneous manifestations. All the relevant data regarding history, clinical examination and investigations were recorded and analyzed.

Results: Of the 100 neonates, 56 (56%) were males and 44 (44%) were females, 72 (72%) were full term, 23 (23%) were pre-term and 5% were post term. Of these 78% newborns were born to multigravidae mothers, while 24% newborns born of consanguineous marriage had cutaneous lesions. The majority of newborns 54% were born through normal delivery. The largest number of babies with cutaneous lesions (72%) was seen in newborns of mothers in the age group of 20-29 years. The most common dermatoses were physiological scaling (18%) and Mongolian spots (20%) followed by milia (13%), miliaria (14%).

Conclusions: The present study helps to understand the type and distribution of cutaneous lesions presenting in the early neonatal period in newborns. Majority of skin lesions were transient and did not need any medical treatment. Counselling the parents helped alleviate their significant psychological stress as well as play a role in creating awareness in the community and benefit the people at large.

Resumo: Investigou-se o movimento conceitual proposto por Davýdov e colaboradores para o ensino do conceito de número no primeiro ano escolar. Trata-se de uma pesquisa teórica cuja fonte de dados é a obra davydoviana. Nesta, o ponto de partida é a análise das relações entre grandezas discretas e contínuas de objetos e fenômenos reais. Nesse estágio, são revelados os elementos que compõem a relação universal que, na sequência, é modelada geometricamente e algebricamente, o que possibilita a redução do concreto ao abstrato. Posteriormente, no procedimento de ascensão do abstrato ao concreto, são introduzidos os números em sua significação aritmética, enquanto singularidade.

Pedagogia e saúde na educação de alunos com deficiência: entre antigas e novas inter-relações
Authors: Freitas Ana Beatriz Machado de
Published: February 2017

Resumo: O artigo traz uma reflexão sobre a influência da área da Saúde no campo da Educação Especial, particularmente na educação de pessoas com deficiência. É reconhecida a importância histórica da área nas origens dessa educação na era contemporânea, bem como na orientação das intervenções educacionais. A Educação Especial constituiu-se caracterizada por um modelo médico de intervenção e apartada da escolarização comum (regular). Com a perspectiva da educação inclusiva, no final do século XX, passou a se estruturar como atendimento que transversaliza todos os níveis da educação regular e a assumir um caráter eminentemente pedagógico. É observado, no entanto, que a pertinência das críticas ao modelo médico e da ênfase às condições sociais que deixam os sujeitos em situação de deficiência/dependência não deve justificar a pouca evidência de conhecimentos da área da Saúde conferida à formação de professores, especialmente nos cursos de Pedagogia. Os conhecimentos dessa área estão estritamente relacionados com os diferenciais do público atendido pela Educação Especial no que concerne a particularidades dos processos de desenvolvimento –inclusive neurodesenvolvimento - e aprendizagem, os quais são objeto de estudo e intervenção do pedagogo.

Актуальность. Частота желчнокаменной болезни в России высока, выполняется много операций на желчевыводящейсистеме, однако возможности урсотерапии используются не в полной мере, так как для нее нет четких диагностическихкритериев.Цель исследования - поиск эффективныхметодов диагностики микрохолелитиаза для определения показаний к виду ле-чебной тактики. Главная задача - реализация на практике методов импедансометрии и микроскопии желчи у больныхмикрохолелитиазом.Материалы и методы. Работа выполнена на материале от 112 больных с различными заболеваниями желчевыводящейсистемы и 4 практически здоровых лиц. Оценивалась желчь, полученная при непрерывном фракционном дуоденальномзондировании, а также желчь, полученная в процессепроведения ЭРХПГ из общего желчного протока путемканюляциипоследнего. Анализ желчи выполнялся на реогастрографе РГГ9-01; микроскопия желчи - при помощи обычного и поляриза-ционного световогомикроскопа.Результаты. Из всех кристаллических структур желчи наибольшее значение имеют кристаллы моногидрата холестерина,гранулы билирубината кальция и кристаллыкарбоната кальция. Корелляция между видами кристалловсоответствуеткомпонентам желчных камней (микролитов).Для различных вариантов течения холелитиаза определен импеданс желчи иее коэффициент литогенности.Заключение. На этапе увеличения литогенности желчи и появления билиарного сладжа патогенетически обоснованнойявляется урсотерапия; при возникновениидестабилизации желчи и появлении кристаллических структур (микрохолелити-аз) возможно ставить показания к хирургическому лечению.Ключевые слова: микрохолелитиаз, импедансометрия и микроскопия желчи.

Актуальность Распространенность желчнокаменной болезни и значительные затраты общества на ее лечение являются одной из проблем современной медицины. До 10 - 15% взрослого населения страдают данным заболеванием. Ежегодно в России регистрируется 800000 новых случаев желчнокаменной болезни (ЖКБ). Особую трудность в лечении представляют пациенты с абдоминальным ожирением III ст, так как увеличение толщины слоя подкожной жировой клетчатки ведёт к появлению значительных технических трудностей во время оперативного вмешательства, увеличивает объём оперативной травмы и ухудшает результаты лечения данной категории больных.Цель исследования Уточнить особенности топографии у женщин с различными типами телосложения страдающих абдоминальным ожирением. Материалы и методы В статье описаны результаты прижизненного топографо - анатомического исследования желчного пузыря (по результатам спиральной компьютерной томографии и 3D-моделирования) у лиц женского пола с различными типами телосложения в условиях абдоминального ожиренияРезультаты и их обсуждение Произведена оценка визуализации (по результатам спиральной компьютерной томографии) анатомических структур брюшной стенки и органов брюшной полости, находящихся в правом подреберье у лиц женского пола в зависимости от типа телосложения и наличия абдоминального ожирения. Предложенная методика 3D-моделирования позволяет провести математические измерения, которые могут послужить основой для расчёта критериев оптимального оперативного доступа при выполнении холецистэктомии.Выводы Наличие абдоминального ожирения не вызывает изменений в топографо-анатомических характеристиках желчного пузыря, однако глубина его расположения существенно увеличивается из-за значительного увеличения толщины подкожной жировой клетчатки.Ключевые слова желчный пузырь, тип телосложения, абдоминальное ожирение
Divisões de classe e pobreza relativa no Brasil
Authors: Santos José Alcides Figueiredo
Published: February 2017

O artigo analisa a evolução, no período de duas décadas, da associação entre classe social e chances de ser pobre nos critérios de renda e de recursos no Brasil. Modelos de regressão logística foram usados para estimar as chances relativas (odds ratio), ajustadas, de estar em situação de pobreza relativa (limiar de 70% da mediana). Na base da estrutura social as desigualdades de oportunidades relativas de ser pobre no critério de renda pessoal disponível, em comparação ao topo privilegiado, mantiveram-se em níveis muito elevados ou ampliaram-se. As chances relativas de ser pobre de recursos ou bens acumulados no período pós 2002 se alteraram pouco ou tiveram certa deterioração para os que têm desvantagens de classe. Os progressos nos padrões de vida da população não se fizeram acompanhar de reduções marcantes na distribuição relativa de fatores protetivos que minimizam riscos e de vulnerabilidades que potencializam riscos de estar em situação de pobreza relativa no contraste entre o topo e a base da estrutura social.

Statistical Models for Corporate Credit Risk Assessment – Rating Models
Authors: Ptak-Chmielewska Aneta
Published: February 2017

Taking into consideration the weakness of the models based on discrimination function (Z-score) proposed by Altman within the conditions of polish economy some attempts were taken in the 90s to adjust these models to the reality of post-communist economy. The initial interest in the models of multivariate discriminant analysis was extended by logistic regression models and then also by neural networks and decision trees. In the recent years some attempts were also taken to apply models of the event history analysis. Rating models based on developed bankruptcy risk models are basic element in credit risk management. Paper focuses on the critical assessment of statistical methods applied and points out the advantages and disadvantages of various approaches toward the estimation of models. Empirical comparative analysis were conducted based on the sample of enterprises. The possible application of statistical models in credit risk assessment of enterprises (rating models) was pointed out.

Imajući u vidu činjenicu da radova na ovu temu ima jako malo, namera autorke je da predstavljanjem  iskustava ovih žena pruži podatke koje mogu poslužiti za dalji istraživački rad u ovoj oblasti.
MASCULIN/FEMININ, UNITATE PRIMORDIALĂ ŞI DISTORSIONĂRI ALE UNITĂŢII
Authors: Dărăbuș Carmen
Published: February 2017

Mit fecund în spațiul european și nu numai, androginul (gr. andros - „bărbat” + gyne – „femeie”) reprezintă, poate, cel mai bine, dorința de perfecțiune, veche aspirație a tuturor civilizațiilor. Sinteza masculinului și a femininului e o ficțiune mitică, filosofică ori artistică, parte a nostalgiei arhetipale, ideal spiritual, dar și supraabundență erotică. De la Platon la gnosticii și misticii Evului Mediu, mai apoi la romanticii europeni, aspiră la acest tip de desăvârșire, mai rudimentar ori mai sofisticat, inițiind ritualuri care să permită accesul la unitatea primordială. O formă de distorsionare a mitului androginului poate fi mitul lui Narcis, în care căutarea jumătății este suspendată, pentru că ființa așa cum este ea, înjumătățită după mitul platonician, divizată la feminin din coasta unui unic trup masculin adamic – sau mai curând androginic -, își este sieși suficientă. O altă formă hibridă este hermafroditismul. În plan mundan, acesta este văzut ca o formă de desacralizare, o deformare și un simulacru.

U radu će biti reči o dosadašnjim arheološkim istraživanjima na bregu iznad Vršca, posebno o sistematskim arheološkim iskopavanjima u periodu od 1997. do 2001. godine. Istraživanjima su utvrđene dimenzije ove srednjovekovne fortifikacije kao i objekti unutar nje. Analizom otkrivenih delova arhitekture, kulturnih slojeva i pokretnih arheolških nalaza, kao i prema poznatim istorijskim podacima, moguće je da se preciznije odredi vreme nastanka i trajanja utvrđenja, njegova stradanja, rušenja, ali i da se ukaže na strukturalne elemente zbog kojih se Vršačko utvrđenje u novijoj literaturi svrstava u zamak.
ZUM VERHÄLTNIS VON VORSTELLUNG UND TRAUM
Authors: Atzert Stephan
Published: February 2017

Vorliegender Aufsatz zeigt auf Grundlage von Schopenhauers „Versuch über das Geistersehn und was damit zusammenhängt“ und anderen Quellen, dass der Wirklichkeitssinn aus der Unterscheidung von Träumen, und nicht, wie von Nietzsche behauptet, aus dem Konflikt des Wachbewusstseins mit dem Traum resultiert. Die Verwandtschaft von Traum und wacher Vorstellung wird dann mit literarischen (Traum-)Beispielen weiter ausgeführt, um zu dem Schluss zu kommen, dass literarische Fiktion zwar nicht die Wirklichkeit, wohl aber u.U. die Wahrheit über die Wirklichkeit ist, ähnlich wie bestimmte Träume die Wirklichkeit widerspiegeln.
SOCIO-DEMOGRAFSKI ČINIOCI USPEŠNOSTI DAROVITIH UČENIKA
Authors: Letić Milena M. , Lungulov Biljana S.
Published: February 2017

U radu su prikazani rezultati istraživanja u oviru kojeg se, sa dva različita aspekta, razmatra problematika uspešnosti darovitih učenika u konkretnom domenu. U prvom delu istraživanja akcenat je stavljen na utvrđivanje postojanja i strukture razlika u nivou uspešnosti učenika darovitih u različitim domenima (muzika, slikarstvo, sport i matematika), a u drugom delu na ispitivanje poveznosti kriterijumske varijable sa socio-demografskim karakteristikama ispitanika (uzrast, pol i nivo obrazovanja roditelja). Varijabla uspešnosti operacionalizovana je preko dve vrste indikatora: školsko postignuće i učešća i nagrade na takmičenjima. Dobijeni rezultati sugerišu da muzički daroviti učenici prednjače u odnosu na ostale ispitanike i u pogledu školske uspešnosti i u pogledu uspešnosti naprednog tipa. S druge strane, rezultati ukazuju na to da uspešnost darovitih učenika ima tendenciju ka menjanju samo u odnosu na uzrast ispitanika, u smislu da stariji učenici postižu bolje rezultate u školi od mlađih. Objašnjenje izostanka povezanosti kriterijumske varijable sa preostalim socio-demografskim karakteristikama moglo bi se potražiti u činjenici da je ispitivani uzorak obuhvatao različite domene darovitosti, zbog čega postoji verovatnoća dobijanja razlika u slučaju njihovog razdvajanja. Stoga se zaključuje da je neophodno da se fenomen darovitosti razmatra u okvirima pojedinačnih domena radi dobijanja preciznijih rezultata i kreiranja adekvatnih pedagoških implikacija.
PROBLEM DISKRIMINACIJE LGBT POPULACIJE U SRBIJI
Authors: Isaković Maja , Lazar Žolt
Published: February 2017

U ovom radu analizira se problem diskriminacije LGBT populacije u Srbiji, odnosno aspekti diskriminacije ove manjinske grupe. Diskriminacija LGBT osoba u ovom radu posmatra se kao neformalna, formalna i strukturalna. Formalnom diskriminacijom smatra se ona koja se događa u okviru državnih ili drugih institucija (zdravstva, prosvete, obrazovanja), zatim diskriminacija od strane desničarskih organizacija, državnih funkcionera i SPC, dok se neformalna diskriminacija odnosi na predrasude, stereotipe, uznemiravanje i ponižavanje u svakodnevnom životu. Strukturalna diskriminacija odnosi se na društveni kontekst i najbolje oslikava društveni položaj LGBT populacije u Srbiji. Zaključak je da za poboljšanje položaja LGBT populacije u društvu nije dovoljno samo postojanje zadovoljavajućih pravnih akata i formalnopravna jednakost. U srpskom društvu strukturalna diskriminacija se javlja kao najveći problem, te su stoga potrebne i dublje strukturne promene na nivou svakodnevnog života. Da bi se prevazišla, različitost se mora prepoznati i prikazati. Uvođenje strukturnih promena naročito je bitno u sferi obrazovanja (tzv. kvir inkluzija), kako bi se prihvatio afirmativan pogled na LGBT populaciju. Glavne strategije promene trebale bi biti usmerene na podizanje svesti putem formalnih i neformalnih obrazovnih kanala.

Published: February 2017

U radu je predstavljen koncept poverenja kao preduslov adaptiranja individua na kompleksno društveno okruženje, kao i koncept ontološke sigurnosti u kontekstu detradicionalizacije i rizika u savremenom društvu. Takođe, u tekstu se demonstrira kako su varijable poverenja i ontološke sigurnosti od posebne važnosti kada je reč o marginalizovanim i diskriminisanim populacijama. U tom smislu, ukazuje se na izuzetan teorijski i praktični značaj fenomena kao što su poverenje u druge, opšti osećaj sigurnosti, obraćanje drugima u teškim situacijama i tome slično.

Published: February 2017

ABSTRACTThe measles is a major cause of child mortality among vaccine preventable disease. The incidence of measles reach out 198 cases in 2014 at Pasuruan. The incidence of measles in Pasuruan, not only in areas with low immunization coverage but also in areas with high immunization coverage, it may indicate the quality of the vaccines given bad that does not provide protection to measles disease. The aim of this study was to analyze the influence of quality of measles vaccine to the incidence of measles in Pasuruan Regency. This study was an analytic observational with case-control approach. The samples of this study taken 30 villages which had measleas cases in 2014 and 30 villages which had not measles cases in 2014. The data was analyzed by using linier regression and logistic regression. The result of the study confirmed that training (p = 0.002), knowledge (p = 0.000), and the availability of vaccine (p = 0.022) effect on the quality of measles vaccine; thus the quality of measles vaccine (p = 0.008) effect on the incidence of measles. The conclusion of this study the influence of which there are knowledge to the quality of measles vaccine; and there is influence between quality of measles vaccine to the incidence of measles. Suggestions can be drawn based on the results of this study, increase health workers knowledge about the measles immunization coverage and the quality of measles vaccine with mentoring, and require officers to use the facilities and infrastructure of immunization according to SOP (Standard Operating Procedure).Keywords: incidence of measles, quality of measles vaccine
On Energy Optimization in Cryptographic Hash Functions and Symmetric Key Protocols
Authors: Roy Swapnoneel , Harish Priyanka , Talluri Raghu
Published: February 2017

In this work we study the energy consumption by various modern secured hash functions (MD2, MD5, SHA-1, and SHA-2) and modern symmetric key encryption protocols (Blowfish, DES, 3DES, and AES) from the algorithmic perspective. We identify various parameters that moderate energy consumption of these hashes and protocols. Our work is directed towards redesigning or modifying these algorithms to make them consume lesser energy. As a first step, we try to determine the applicability of the asymptotic energy complexity model by Roy et. al. on these hashes and protocols. Specifically, we try to observe whether parallelizing the access of blocks of data in these algorithms reduces their energy consumption based on the energy model. Our results confirm the applicability of the energy model on these hashes and protocols. Our work is motivated by the relevance and importance of cryptographic hashes and symmetric key protocols for modern ICT (Information and Communication Technology), and ICT enabled industry to keep them protected from dynamically changing threat scenarios. Hence the design of more energy efficient hashes and protocols will definitely contribute in reducing the ICT energy consumption that is continuously increasing.

Introducción: actualmente se considera que la acumulación de grasa corporal a nivel central se asocia con la presencia de hipertrigliceridemia, hipertensión arterial y diabetes. El índice de masa corporal (IMC) se ha utilizado para identificar la obesidad en la población general, pero no permite determinar la distribución de la grasa corporal, por lo que se pueden utilizar otras medidas antropométricas para evaluar la adiposidad y determinar su relación con la presencia de alteraciones metabólicas que presentan las personas con exceso de peso.Objetivo: evaluar las medidas antropométricas como el índice cintura-cadera (ICC), IMC y circunferencia de cintura (CC) como indicadores predictivos de factores de riesgo metabólico en población mexicana adulta. Métodos: se realizó un estudio transversal descriptivo en un total de 490 personas (27-46 años), agrupadas por género. A todos los participantes se les determinaron medidas antropométricas y parámetros bioquímicos. Se crearon curvas ROC de los parámetros antropométricos para identificar el mejor indicador predictivo de riesgo metabólico.Resultados: el factor de riesgo metabólico con mayor prevalencia después de la obesidad abdominal en mujeres fue la hipertrigliceridemia, seguido de la hiperglicemia, hipercolesterolemia y presión arterial elevada, que se encontraron con mayor frecuencia en los hombres, aunque la presencia de obesidad abdominal se encontró con mayor frecuencia en las mujeres (73,9 vs.37,3 %). La circunferencia de cintura fue el mejor indicador predictivo para presentar uno o más factores de riesgo metabólico [área bajo la curva ABC = 0,85 (IC 95%, 0,78-0,92)], seguido del IMC [ABC = 0,79 (IC 95%, 0,72-0,88)] y por último el ICC [ABC = 0,63 (IC 95%, 0,52-0,74)]. Además, se observó que la obesidad abdominal duplica el riesgo de presentar el síndrome metabólico.Conclusión: la circunferencia de cintura es el mejor indicador de riesgo metabólico en ambos sexos en comparación con el IMC y el ICC.
Coupling Dairy Manure Storage with Injection to Improve Nitrogen Management: Whole‐Farm Simulation Using the Integrated Farm System Model
Authors: Duncan E. W. , Kleinman P. J. A. , Beegle D. B. , Rotz C. A.
Published: February 2017

Core Ideas

Manure storage and injection strategies were simulated using the Integrated Farming Systems Model.

Strategies were verified using field data.

We compared manure storage in environmental and economic model outputs.

Introducing 6 mo of storage on a PA dairy farm decreased whole‐farm NUE without manure injection.

Manure injection and 6 mo of storage gave the best combination of profit and environmental outcome.

Application of livestock manure to farm soils represents a priority nutrient management concern in the Chesapeake Bay watershed. Historically, strong emphasis has been placed on adding manure storage to dairy operations, with the recognition that manure application methods can be improved. The Integrated Farm System Model was used to simulate manure management on a typical Pennsylvania dairy farm (100 milking cows, 80 ha). Converting the operation from daily haul to 6 mo of storage with broadcast application did not substantially change nitrogen (N) losses to the environment. However, switching to manure injection conserved ammonium N and improved manure N use efficiency by crops, even though it increased N leaching by 27% with 6‐mo storage and 13% with 12‐mo storage. Increasing manure storage from 6 to 12 mo with manure injection reduced nitrate N leaching by 38%, due to better timing of manure application to crop growth, but lowered annual net returns. Overall, manure injection and 6 mo of storage resulted in the best combination of profit and environmental outcome.
Influence of Cattle Trails on Runoff Quantity and Quality
Authors: Miller Jim J. , Curtis Tony , Chanasyk David S. , Willms Walter D.
Published: February 2017

Cattle trails in grazed pastures close to rivers may adversely affect surface water quality of the adjacent river by directing runoff to it. The objective of this 3‐yr study (2013–2015) in southern Alberta, Canada, was to determine if cattle trails significantly increased the risk of runoff and contaminants (sediment, nutrients) compared with the adjacent grazed pasture (control). A portable rainfall simulator was used to generate artificial rainfall (140 mm h−1) and runoff. The runoff properties measured were time to runoff and initial abstraction (infiltration), total runoff depth and average runoff rates, as well as concentrations and mass loads of sediment, N, and P fractions. Cattle trails significantly (P ≤ 0.10) decreased time to runoff and initial abstraction (26–32%) in the 2 yr measured and increased total runoff depth, runoff coefficients, and average runoff rates (21–51%) in 2 of 3 yr. Concentrations of sediment, N, and P fractions in runoff were not significantly greater for cattle trails than for control areas. However, mass loads of total suspended solids (57–85% increase), NH4–N (31–90%), and dissolved reactive P (DRP) (30–92%) were significantly greater because of increased runoff volumes. Overall, runoff quantity and loads of sediment, NH4–N, and DRP were greater for cattle trails compared with the adjacent grazed pasture, and hydrologic connection with cattle‐access sites on the riverbank suggests that this could adversely affect water quality in the adjacent river. Extrapolation of the study results should be tempered by the specific conditions represented by this rainfall simulation study.

Core Ideas

Runoff quantity was significantly increased in cattle trails compared with adjacent grazed pasture.

Cattle trails did not increase contaminant concentrations in runoff.

Mass loads of TSS, NH4–N, and DRP were significantly greater because of increased runoff volumes.

Field observations revealed a hydrologic link between cattle trails and river.

Runoff in cattle trails may adversely impact water quality in adjacent rivers.
