Importance of the methodology report in Electrical Bioimpedance on body composition studies

Por medio de la presente nos dirigimos a usted, pues hemos leído con interés la publicación “Estado nutricional en estudiantes universitarios: su relación con el número de ingestas alimentarias diarias y el consumo de macronutrientes” de Pi et al1 . En este estudio, los autores utilizaron como métodos antropométricos el Índice de Masa Corporal (IMC), la Circunferencia Abdominal (CA) y la Bioimpedancia Eléctrica (BIA) para estimar el estado nutricional y la composición corporal (CC). Se sabe que la BIA es usada para la estimación de la grasa corporal, sin embargo es específica para cada población, por lo que es necesario validar en cada población de estudio para disminuir un potencial sesgo de medición .

The perceived risk and safety management

Introducción: El personal de emergencia convive habitualmente con riesgos inherentes a su profesión. Objetivos: Profundizar acerca del concepto del riesgo percibido como herramienta para gestionar el riesgo ocupacional. Materiales y métodos: El modelo utilizado para la cuantificación del riesgo ha sido el paradigma psicométrico. De esta forma, se realizaron encuestas anónimas en las diferentes estaciones de bomberos. El cuestionario contenía preguntas sociodemográficas, nueve preguntas acerca de distintos atributos del riesgo y una pregunta acerca de la percepción del riesgo en general del sujeto. Resultados: El análisis estadístico muestra dos grupos claramente diferenciados en cuanto a su percepción del riesgo, siendo uno de ellos caracterizado por tener sus integrantes una alta percepción del riesgo y el otro por tener una baja percepción del riesgo. Por último, se muestra que solamente el nivel educacional era una variable significativa en la explicación del riesgo percibido. Conclusiones: Los resultados son discutidos en función de la literatura existente concluyendo que se debe formar a los trabajadores para elevar su percepción del riesgo.

Pricing and spread components at the Lima Stock Exchange

This paper analyses three aspects of the share market operated by the Lima Stock Exchange: (i) the short-term relationship between the pricing, direction and volume of order flows; (ii) the components of the spread and the equilibrium point of the limit order book per share, and (iii) the pricing, order direction and trading volume dynamic resulting from shocks in the same variables when lagged. The econometric results for intraday data from 2012 show that the short-run dynamic of the most and least liquid shares in the General Index of the Lima Stock Exchange is explained by the direction of order flow, whose price impact is temporary in both cases.

When Do Citations Reflect “Impact?”

Citation behaviors vary widely between and within STM and HSS; within particular disciplines citations can also play sharply different kinds of roles. The complexity of adducing scholarly significance from citation metrics is further increased as scholars may use citations differently from one publication to the next.  The Chicago Manual of Style (16th Ed.) tells us in Chapter 14.1 that the basic “purpose of source citations” is, as a requirement of “ethics, copyright laws, and courtesy to readers” to “identify the source of direct quotations or paraphrase and of any facts or opinions not generally known or easily checked.” “Conventions vary according to discipline,” theCMS cautions, “the preferences of publishers and authors, and the needs of a particular work.” The CMS doesn’t have much to say about citation indices, and impact.

Deceptive Publishing: Why We Need a Blacklist, and Some Suggestions on How to Do It Right

In an earlier posting, I suggested that the term “predatory publishing” has perhaps become too vague and subjective to be useful, and I suggested “bad faith” as a possible replacement term. But in light of the subsequent discussion in the comments section of that posting and after continuing to think about the issue, I’d like to suggest another alternative to “predatory,” one that offers more precision and usefulness: “deceptive.” Deception, it seems to me, is the common thread that binds all of the behaviors that are most commonly cited as “predatory” in journal publishing, and I think it’s the most meaningful and appropriate criterion for placing a publisher on a blacklist. Furthermore, “deception” is (unlike “predation”) a concept with a fairly clear and unambiguous meaning in this context.
