The second-curve model: a promising framework for ethical consumption? Veganism as a case study
Innovation and diffusion theories have a long tradition in marketing and consumer behaviour literature (Black 1983; Petrosky 1991; Rogers 1976, 2003). However, thus far, little research has been conducted into understanding the diffusion (and adoption) process of ethical consumption under innovation theories (Carrigan, Moraes, and Leek 2011), even though ethical consumption has been recognised as an innovation trend (Ganglmair-Wooliscroft and Wooliscroft 2015; Lundahl 2014). The aim of this paper is to build on the literature on ethical consumption from the lens of the theories of innovation and, specifically, from diffusion theory. First, key concepts regarding these theories are given. Second, ethical veganism (hereafter, veganism) is used as a case study to show how the second-curve model offers an opportunity to reframe the understanding of ethical consumption and, subsequently, its analysis. Finally, some implications for researchers and practitioners are considered
The genus <i>Chlamydotheca</i> Saussure (Crustacea: Ostracoda) in northeastern Argentina
The genus Chlamydotheca Saussure, 1858 is a typical representative of the Neotropical ostracod fauna that occupies lotic and lentic environments including temporary and permanent ponds. Up to the present, four species have been recorded in Argentina: C. iheringi (Sars), C. incisa (Claus) and C. leuckarti (Claus), and C. symmetrica (Vávra). Temporary and permanent ponds of this region were sampled for ostracods, using a fine mesh net. Three species belonging to the genus Chlamydotheca were collected of which C. arcuata (Sars) is recorded for first time for the Chacoan region. Limb morphology was studied under light microscope and line drawings were made using camera lucida. Valves were photographed under scanning electron microscope and redescriptions of C. arcuata and C. iheringi are provided and distributional aspects of the species sampled are discussed.Facultad de Ciencias Naturales y MuseoConsejo Nacional de Investigaciones Científicas y Técnica
Postembryonic development of nonmarine ostracod <i>Chlamydotheca arcuata</i> (Sars, 1901) (Crustacea: Ostracoda), reared in the laboratory
We describe here 8 instars (from A-8 through A-1) of the postembryonic development of the Cyprididae Chlamydotheca arcuata (Sars, 1901) from hatching to sexually mature individuals. To study the development of this species, cultures of adult parthenogenetic female specimens were established and maintained in the laboratory. The ostracod specimens were collected from temporary ponds and streams in Buenos Aires Province, Argentina. This report provides a description of the chaetotaxy of each limb along with detailed illustrations. Photographs of eggs and carapaces were taken using scanning electron microscopy. The complete development of Chlamydotheca arcuata lasted between 80 and 90 days. In the first instars, the active swimmers are characterized by carapaces that have a greater height in front of the first half of the maximum length and taper toward the rear end to become pointed. The appearance and numbers of the sensory setae on the carapace increase in the latest instars.Facultad de Ciencias Naturales y Muse

PROPUESTA DE IMPLEMENTACIÓN DE LOS P.G.H BASADO EN LA NORMA SANITARIA N°749-2012, PARA MEJORAR LA INOCUIDAD DE LOS ALIMENTOS EN EL ÁREA DE COCINA DEL HOSPITAL REGIONAL LAMBAYEQUE
Actualmente, la Inocuidad de los Alimentos y la presencia de enfermedades debido a su defectuosa manipulación y la contaminación, constituyen un foco de preocupación, dado que generan gastos en salud pública y pérdidas humanas, impactando negativamente en el comercio y en la salud. La importancia de la inocuidad se ha caracterizado por ser una herramienta indispensable para la calidad en los alimentos, como base de competitividad y protección a la salud. Los principios básicos de higiene, son principios que se involucran desde la manipulación, preparación, hasta el almacenamiento de dichos alimentos, con el objeto de garantizar que se fabriquen en condiciones sanitarias adecuadas y se disminuyan los riesgos inherentes a la producción. En ese contexto, el presente trabajo de investigación tuvo como objetivo proponer la Implementación de los principios generales de higiene basado en la norma sanitaria N°749-2012, para mejorar la inocuidad de los alimentos en el área de cocina del Hospital Regional Lambayeque. Para esto, se efectuó el diagnóstico y revisión de la documentación interna del hospital, realización del mapa de procesos del mismo, realización de visitas a las áreas correspondientes efectuando entrevistas propicias y por ultimo aplicación de la ficha de evaluación sanitaria. Con los resultados obtenidos y en razón de condiciones actuales, el hospital cumple en un 72.7% de los requisitos, lo cual se ubica dentro del calificativo “En Proceso”. Como aporte final se elaboró un Manual de Buenas Prácticas de Higiene para el mismo Hospital.Tesi
Pobres obreritas
Despidos, cierre de empresas, merma del poder adquisitivo, bloqueo de paritarias, presentismo, son tan sólo algunas de las aciagas consecuencias de las políticas de Cambiemos que impactan de forma particular sobre las trabajadoras, pero también encuentran en ellas una de sus principales resistencias. Sin embargo, ni este indiscutible protagonismo en los combates sindicales ni su histórica participación en el mundo laboral han logrado acabar con la idea subyacente de que son recién llegadas o pasajeras en tránsito. Continuidades y rupturas de una presencia que, en el cruce entre la producción y la reproducción, el trabajo y la familia, pone en cuestión el contrato fundante de la modernidad y apuesta a la emancipación.Facultad de Periodismo y Comunicación Socia
Metales pesados: aspectos ecológicos y tecnológico-alimentarios
Se realizó un estudio tendiente a determinar el contenido de algunos metales pesados en material biológico empleado habitualmente como indicador de contaminación ambiental. incluyéndose ciertos alimentos de consumo humano v animal. Muestras. de especies marinas fueron obtenidas del área costera de la V Región de Chile y productos derivados de ellas se recolectaron de industrias y establecimientos de alimentos ubicados en las regiones l. V, VIII y Región Metropolitana de Chile. Muestras de especies vegetales se recolectaron de campos de cultivos y establecimientos de alimentos localizados en la Región Metropolitana. Los análisis se efectuaron por los métodos del dietilditiocarbamato de plata en piridina. fluorescencia de rayos X (FRX) y especrrofotometría de absorción atómica. Los resultados obtenidos muestran elevados niveles de arsénico en algas (7.6 mglkg. base húmeda), cadmio y plomo en peces marinos. especialmente en el esqueleto de jurel (0.25 mglkg y 2.26 mglkg. sobre bases húmedas respectivamente). Igualmente se destaca el alto contenido de mercurio en harina y aceite de pescado (0,7 mglkg, base húmeda) y plomo en lechuga (3.5 mglkg. base húmeda). Estos resultados muestran que existe contaminación ambiental debido a metales pesados y se sabe que esos contenidos implican daño en la salud humana y animal
Implementación de recursos audiovisuales como estrategia de validación pedagógica
This paper is the outcome of a quasi-experimental research, whose objective was to validate an educational strategy aimed at implementing audiovisual learning resources in educational institutions. Its theoretical foundation was configured through two variables: educational practices (dependent variable), and audiovisual resources (independent variable). With a control group model comprised of 11th grade students from the Institución Educativa Camilo Torres of Mocarí (Montería, Colombia), it was possible to identify the most frequent learning needs of secondary education students, to classify the audiovisual educational resources available to the teachers, and to model, implement and validate an educational strategy by assembling three audiovisual products, three radio programs, and a blog.O presente artigo é produto de uma pesquisa com desenho quase experimental, cujo objetivo foi validar uma estratégia pedagógica para implementar recursos didáticos audiovisuais em instituições educativas.
