John Boardman has recently published a Sam Wide Group cup, on the interior of which is painted a caricature of Oedipus and the Sphinx. His accompanying illustration (Plate II 1) fully confirms the interpretation offered, that the Theban Sphinx— for once, in its physiognomy as well as in its anatomy, obtrusively male—is committing the nuisance of public masturbation. Although such offensive conduct seems, as Boardman observed, inexplicable within the Sphinx's mythic context, the artist's motive for this innovation becomes clearer if one can detect here an instance of the easy ‘glide from the contemporary into the mythical world’.First, however, it should be recalled that, at least as early as Aeschylus' satyr play Sphinx, the Theban pest could be called Σφίγγα δυσαμϵριᾱν πρύτανιν κύνα (182 Mette, 236 Nauck).

Inhibitors of cholinesterases are a wide group of low molecular weight compounds with a significant role in the current pharmacology. Besides the pharmacological importance, they are also known as toxic compounds like military nerve agents. In the pharmacology, drugs for Alzheimer disease, myasthenia gravis and prophylaxis of poisoning by nerve agents can be mentioned as the relevant applications. Besides this, anti-inflammation and antiphrastic drugs are other pharmacological applications of these inhibitors. This review is focused on a survey of cholinesterase inhibitors with known or expected pharmacological impact and indications of their use. Recent literature with comments is provided here as well.

AbstractThe recent years have seen a significant interest in the applications of nanotechnology in various facets of our lives. Due to their increasingly widespread use, human exposure to nanoparticles (NPs) is fast becoming unavoidable. Among the wide group of nanoparticles currently employed in industry, titanium dioxide nanoparticles, TiO2 NPs, are particularly popular. Due to its white colour, TiO2 is widely used as a whitening food additive (E 171). Yet, there have been few studies aimed at determining its direct impact on bacteria, while the available data suggest that TiO2 NPs may influence microbiota causing problems such as inflammatory bowel disease, obesity, or immunological disorders. Indeed, there are increasing concerns that its presence may lead to intestinal barrier impairment, including dysbiosis of intestinal microbiota. This article aims to present an overview of studies conducted to date with regard to the impact of TiO2 NPs on human microbiota as well as factors that can affect the same. Such information is necessary if we are to conclusively determine the potential toxicity of inorganic nanoparticles.

Regional Public Education Officers of the Royal College of Psychiatrists are strategically placed to influence and improve the coverage of mental health issues in the media. Their role needs to be enhanced and clarified, and a proposal is being put forward in the College to achieve this. One possible way of working locally is illustrated through the work of West Midlands Insight, which demonstrates the value of working with a wide group of people, including those who have experienced mental ill health.

AbstractThe European Union has been facing common issues such as early school leaving and lifelong learning for years. They are main targets that remain on the EU agenda and all good practice examples are welcome. Citizen science is one of the approaches that seems to have great potential to draw a wide group of people to science in a popular way. People can easily become a part of a scientific team and contribute to research that could hardly be carried out by one small team. Many citizen science researchers deal with issues that are attractive for people because of their usefulness or application (gathering ticks, taking photographs of surroundings) and/or because of the accessibility of the data (typical for biological issues). This aspect also supports bridging the gap between citizens-amateurs and scientists-professionals, as well as lifelong learning. Chemistry is a natural science subject that is rarely performed in citizen science, and little research is devoted to the educational aspect of citizen science projects. Therefore, we present here a brief overview of an increasing scientific design that is widely used in natural science, although rarely in chemistry. Citizen science seems to be a potentially useful tool for improving chemistry education.

Dietary supplements are a wide group of products belonging to the food category. Their sales are still growing. The composition, appearance and the intended use of these products make them resemble drugs. Dietary supplements are designed to meet the specific requirements of different consumer groups. Many dietary supplements contain herbal substances or their preparations. The safety of the herbal material is particularly affected by its proper identification, the part of the plant used as well as the standardization of the extract for a specific biologically active compound. Regardless of the group of consumers for which these products are intended, the risks associated with taking dietary supplements may relate to their contamination with heavy metals, pesticide residues or pathogenic microorganisms. There may also be adulterated dietary supplements on the market, the real composition of which differs from the composition presented on the original packing. Furthermore, the presence of restricted hazardous substances, or limited substances on the product is undoubtedly dangerous to health.

Intellectual property and cultural policy are essential to the practice of cultural rights, however, in both legal frameworks, indigenous peoples have often found that the state has little consideration for their voices and their world views. In contrast, though no more representative of indigenous perspectives, the social sciences, while engaging with indigenous voices, have often treated them as a source to be appropriated with disregard of their rights and agency. Through an activist and collaborative methodology that includes the concerns of a wide group of indigenous and non-indigenous persons, this article explores how the oral history project of the Fogata Kejtsitani in the Purhépecha community of Cherán, México, contributes to discussions on the appropriation and dissemination of culture. This community has managed the recognition of their right to autonomy, and in so doing, has founded a continuous process of law creation, on which Kejtsitani takes part. La propiedad intelectual y la política cultural son esenciales para la práctica de derechos culturales, sin embargo, en ambos marcos jurídicos los pueblos indígenas frecuentemente han encontrado que el Estado tiene poca consideración por sus voces y cosmovisiones. En contraste, aunque sin ser más representativo de las perspectivas indígenas, las ciencias sociales que se han relacionado con voces indígenas, frecuentemente las han tratado como una fuente para ser apropiada, descartando sus derechos y agencia. A través de una metodología activista y colaborativa que incluye las inquietudes de un amplio grupo de personas indígenas y no-indígenas, este artículo explora cómo el proyecto de historia oral de la Fogata Kejtsitani en la comunidad Purhépecha de Cherán, México, contribuye a las discusiones sobre la apropiación y diseminación de la cultura. Esta comunidad ha logrado el reconocimiento de su derecho de autonomía y, al hacerlo, ha fundado un proceso continuo de creación de derecho del cual Kejtsitani también forma parte.

Background: Conceived as a unit of lasting cultural (mostly vertical) trait transmission, memes now include transient horizontally transmitted fads. Memes may sometimes follow the logic of population genetics, e.g. learned birdsong, but not always over the diverse range found in human hosts. Much current work focuses on selection of memes rather than hosts. Methods: We analyze equilibrium between gene-meme and meme-meme competing propagators and consider whether a meme is linked to reproduction (e.g. vertical culture transmission), or not. We employ a genetic component and combined meme induced fitness components for hosts, while memes have replication factors to distinguish from what’s good for the host (fitness). To anticipate future meme effects on population stability we use a Monte Carlo simulation roughly calibrated to the Industrial Revolution. Results: A basic effective calculus of memetic trait competition and interaction with genes is derived and analyzed. The transient nature of short term memes may be a defense against accumulation of deleterious memes. Horizontally transmitted (panmictic) memes with high spreading rate will often not equalize with a genetic trait, spreading outside of natural selection of the hosts, presenting a cumulative existential threat. Vertical transmission reduces replication rate and allows group selection against deleterious memes. Competing mutually exclusive memes contribute to inequality and altruism, but compete through adverse fitness since exclusivity assumes low conversion. Conclusions: The advantage of a portfolio of groups or species may not accrue to a single group. This analytical understanding elevates meme-risk to the level of a candidate solution to the so-called Fermi Paradox, as interstellar travel might require a planet wide group.

EnglishThis paper explores the differences and similarities in three social work processes as viewed by social workers in Norway and Cuba. Contrasting social work processes in these exemplars of de-familialized and familialized welfare contexts offer insight into where social work practices can be governed by international and universal policy, and where context specific national policies may be more appropriate. A qualitative study and thematic analysis based on four focus group interviews (two in each country), with a total of 19 social workers from the respective contexts, were conducted. An international validated vignette of a typical social work case was employed as a tool to help facilitate a group interaction and discussion. The first is an engagement process: how social workers make their decisions on how, or if, to engage with clients. Both Cuban and Norwegian social workers will respond to a client in need, prioritizing children in particular. A second process related to the social worker is needing to obtain a considered overview of the case. Norwegian social workers rely heavily on information about the case coming from the client, and formal rules restrict information flows between services. In Cuba, clients are important and the participation of the family is obligatory, with social workers drawing on a wide group of stakeholders to gather information. The final process is one of distributing responsibility for care and support among the appropriate services and actors. In Cuba, social workers emphasize the family`s role in resolving the case. There is a cultural element here based on the role of the family, but a lack of state services and resources available for social workers in practice is also relevant. In Norway, the Welfare State presents more resources, although social workers refer instead to difficulties in coordination between services. Professionals are held to account in Cuba, whereas institutions take responsibility in Norway. SpanishProcesos de división del trabajo en Trabajo social con familias en Cuba y Noruega. Este artículo explora las diferencias y similitudes en tres procesos del trabajo social a partir de la visión de trabajadores sociales de Noruega y Cuba. A partir de contrastar los procesos del trabajo social en estos casos ejemplares de contextos de bienestar de-familiarista y familiarista respectivamente, el artículo ofrece una visión de hasta dónde la práctica del trabajo social puede estar gobernada por políticas universales e internacionales, y hasta dónde lecturas más específicas según el contexto de las políticas nacionales puede ser más apropiado.  Fue desarrollado un estudio cualitativo con un análisis temático basado en cuatro entrevistas a grupos focales (dos en cada país), con un total de 19 trabajadores sociales en ambos contextos. Par el estudio temático se utilizó una viñeta que valida un caso típico para el trabajo social, como herramienta que facilitó la interacción grupal y la discusión. El primer proceso identificado fue el de comprometimiento con el caso: este alude a cómo los trabajadores sociales toman sus decisiones sobre cómo se involucran, o incluso si lo hacen o no, con los clientes. Trabajadores sociales de ambos países responderán a un cliente que lo necesite, priorizando en particular a los niños. Un segundo proceso se relaciona con la necesidad de los trabajadores sociales de obtener una descripción adecuada del caso. Trabajadores sociales de Noruega se apoyan fuertemente en la información proveída por el cliente y en las reglas formales que restringen el flujo de información entre los servicios. Para el caso de los cubanos, los clientes son importantes, y la participación de la familia es vista como obligatoria, pero se apoyan en un amplio grupo de posibles interesados para recopilar información. El proceso final tiene que ver con la distribución de responsabilidades de cuidado y apoyo entre los servicios apropiados y los actores. En Cuba los trabajadores sociales enfatizan en el rol de la familia para la resolución de los casos. Aquí se aprecia un elemento cultural que refuerza la intervención de la familia, pero a la vez la escasez de servicios públicos o recursos para la práctica del trabajo social en familias. En Noruega, el Estado de Bienestar ofrece más recursos, pero los trabajadores sociales refieren en cambio dificultades para la coordinación de la variedad de servicios disponibles. Los profesionales en Cuba retienen más responsabilidad, mientras que en Noruega las instituciones toman más responsabilidades.

Los micronutrientes son componentes minoritarios pero esenciales de nuestra dieta. Actualmente existe una creencia en los países occidentales desarrollada y apoyada por evidencias científicas que supone que el consumo de ciertos micronutrientes previene importantes problemas de salud. Se alude a un fenómeno conocido como estrés oxidativo, que es causa de envejecimiento y degeneración celular y que puede ser contrarrestado mediante el consumo regular de micronutrientes antioxidantes. En concreto, entre el amplio colectivo de personas que practican deporte, esta creencia está muy extendida y arraigada y las ventas de determinados productos se han disparado en las dos últimas décadas, suponiendo un gran mercado de consumo para las empresas del sector; de hecho es frecuente encontrar en la mayoría de los centros deportivos y gimnasios de nuestras ciudades algún estante en el que se exhiben para su venta complementos nutricionales que contienen productos antioxidantes que prometen mejorar la salud y el rendimiento… El presente trabajo pretende responder a la cuestión acerca de la necesidad o conveniencia de emplear suplementos nutricionales antioxidantes para mejorar la salud de las personas que practican deporte de forma regular.Abstract: Micronutrients are minority but essential components of our diet. Nowadays a belief exists in the western countries developed and supported by scientific evidences that it supposes that the consumption of certain micronutrients prevents serious health problems. One alludes to a phenomenon known as oxidative stress, that is a reason of aging and cell degeneration and that can be offset by means of the regular consumption antioxidant micronutrients. In fact, among the wide group of persons who practise sport, this belief is very widespread and deep-rooted and the sales of certain products have gone off in last two decades, supposing a great consumer market for the companies of the sector; of fact it’s frequent to find in the majority of the sports centers of our cities some shelf in which there show themselves to sale nutritional complements that contain antioxidant products that promise to improve the health and performance … the present work tries to answer to the question brings over of the need or convenience of using nutritional antioxidant supplements to improve the health of the persons who practise sport.

The voluminous letter collection of Barsanuphius and John of Gaza contains 850 letters written by the two sixth-century anchorites who lived in cells near the monastery of Abbot Seridos in Tawatha a village a few miles southwest of Gaza. Barsanuphius and John, referred to as the Old Men of Gaza, were ascetic colleagues who wrote letters of spiritual direction to a wide group of disciples. The earliest manuscripts containing this correspondence date to the eleventh century; however, the collection was originally compiled by a member of Barsanuphius and John’s own monastic community (perhaps Dorotheos of Gaza) shortly after the death of John and the complete seclusion of Barsanuphius. The monk who compiled the collection followed a traditional practice among ancient editors, grouping the letters according to addressees, rather than chronologically. The collection begins with letters to individually named monks and continues with letters addressed to unidentified monks or the brothers of community collectively. The collection contains a series of letters to Aelianos, a layman newly elected as abbot of the monastery, and a large group of letters to lay Christians who sought spiritual guidance from the anchorites. The collection concludes with letters concerning episcopal elections in Gaza and Jerusalem and correspondence to civic officials and bishops in the region.
