Construcción participativa del perfil con base en competencias del docente titular de bachillerato

El objetivo de este trabajo fue construir el perfil del docente titular del bachillerato Cervantes Loma Bonita a través de la investigación-acción. Esta metodología permitió trabajar colaborativamente con los docentes titulares las competencias y desempeños que constituyen dicho perfil, con lo que se generó un diálogo entre ellos en el que estuvieron presentes tanto las experiencias de la vida cotidiana como los referentes teóricos e institucionales relacionados con la acción tutorial. Lo que se pretendió fue que a partir de dicha construcción colaborativa, se tuviera claridad sobre cuáles son las funciones de los titulares, no con el afán de limitar su trabajo ni determinarle exactamente lo que debe hacer, sino para marcar las líneas de acción que deben tener presentes y los desempeños concretos que orientan su acción formativa

What Does it Mean to Be a Cultural Omnivore? Conflicting Visions of Omnivorousness in Empirical Research

The ‘omnivore’ hypothesis currently dominates the academic literature on the social patterning of taste. It argues that cultural elites no longer resemble the traditional stereotype of an elitist snob. Instead, they are more likely to be ‘omnivores’ with broad tastes encompassing both elite and popular cultural forms. The omnivore hypothesis has inspired more than two decades of research and debate, without a clear resolution. In this article, we argue that progress in the omnivore debate has been impeded in part due to an elision of two distinct interpretations of the omnivore hypothesis: a strong interpretation, which holds that cultural elites are generally averse to class-based exclusivity; and a weak interpretation which holds that, while elites have broad tastes which encompass popular forms, they do not necessarily repudiate class-based exclusion. We demonstrate how drawing this distinction helps to clarify the existing empirical evidence concerning the omnivore hypothesis

The Veterinary Identity: A Time and Context Model

The nature of professionalism teaching is a current issue in veterinary education, with an individual’s identity as a professional having implications for one’s values and behaviors, as well as for his or her career satisfaction and psychological well-being. An appropriately formed professional identity imparts competence in making complex decisions—those that involve multiple perspectives and are complicated by contextual challenges. It enables an individual to act in a way that aligns with his or her professional values and priorities, and imparts resilience to situations in which one’s actions are dissonant to these personal beliefs. There are challenges in professionalism teaching that relate to student engagement and faculty confidence in this area. However, these cannot be addressed without first defining the veterinary professional identity—in effect, the aim of professionalism teaching. In this article, existing identity models from the wider literature have been analyzed through a veterinary lens. This analysis was then used to construct a model of veterinary professional identity that incorporates the self (personal morals and values), social development (learning from the workplace environment), and professional behaviors. Individuals who form what we have termed self–environment–behavior connections are proposed to be able to use workplace learning opportunities to inform their identity development, such that environmental complexity does not obstruct the link between values and behaviors. Those who fail to connect with the environment in this way may perceive that environmental influences (e.g., the client, financial limitations) are obstructive to enacting their desired identity, and they may struggle with decision making in complex scenarios

Evaluación del efecto del Pectimorf en el establecimiento in vitro de yemas axilares de boniato clon CEMSA 78-354

With the purpose of studying the effect of different Pectimorf dose in the establishment and budding of axillary buds of sweet potato starting from buds, tuberous roots belonging to the clone CEMSA 78-354 were collected and placed in flasks with water in the laboratory under semicontrolled conditions to induce the sprouting of the buds. Later on, axillary buds of the buds of the tubers (establishment) and axillary buds coming from in vitro plants (multiplication)were selected as sowing material (explants), which were sowed in the Murashige and Skoog culture medium containing the MS salts, thiamin (1 mg.l-1), myoinositol (100 mg.l-1), sucrose (3%), gelryte (2 g.l-1), giberelic acid (10.0 mg.l-1) and indol-3-acetic acid (0.05 mg.l-1) and the already mentioned culture medium without the previously refered regulators of the growth with different Pectimorf concentration: 5.0, 10.0 and 15.0 mg.l-1. The morphological behavior of the in vitro plantas was evaluated to the five, fifteen and thirty days after established the buds under in vitro conditions , and different variables related with the in vitro growth of the buds were analyzed, among which we have: number of sprouted buds, height of the in vitro plants (cm), number, longitude and width of the leaves, buds with roots, longitude of the roots (cm) and longitude of the petiole (cm). The best results were obtained when using the axillary buds coming from budding of tuberous roots in comparison with the axillary buds of the in vitro plants and with the use of the culture medium containing 10.0 mg.l-1 of Pectimorf.Key works: Ipomoea batatas, micropropagation, oligogalacturonidesCon la finalidad de estudiar el efecto de diferentes concentraciones de Pectimorf en el establecimiento in vitro de yemas axilares de boniato, fueron recolectadas raíces tuberosas pertenecientes al clon CEMSA 78-354 y se colocaron en frascos con agua en el laboratorio en condiciones semicontroladas para inducir la brotación de las yemas.

National Mass Drug Administration Costs for Lymphatic Filariasis Elimination

Lymphatic filariasis (LF), commonly known as elephantiasis, is a profoundly disfiguring parasitic disease caused by thread-like nematode worms. This disease can often be disabling, thus reducing the potential productivity of the affected individuals. The WHO places the number of people at risk in 83 countries at 1.307 billion. This study was undertaken in seven countries—Burkina Faso, Ghana, Egypt, Tanzania, the Philippines, the Dominican Republic, and Haiti—using a common protocol to determine the costs of mass drug administration (MDA) programs to interrupt transmission of infection with LF, because there is lack of sufficient information about the costs of these programs. The results demonstrate that LF MDA is affordable and relatively inexpensive when compared to other public health programs. In the context of initiatives for integrating programs for the control and elimination of neglected tropical diseases, this study adds specifically to the relatively scarce body of information about the costs of MDA programs for LF. It also adds to the general knowledge about the application of methods that can be used to estimate the costs and cost-effectiveness of an integrated approach

Imaging the Impact of Chemically Inducible Proteins on Cellular Dynamics In Vivo

The analysis of dynamic events in the tumor microenvironment during cancer progression is limited by the complexity of current in vivo imaging models. This is coupled with an inability to rapidly modulate and visualize protein activity in real time and to understand the consequence of these perturbations in vivo. We developed an intravital imaging approach that allows the rapid induction and subsequent depletion of target protein levels within human cancer xenografts while assessing the impact on cell behavior and morphology in real time. A conditionally stabilized fluorescent E-cadherin chimera was expressed in metastatic breast cancer cells, and the impact of E-cadherin induction and depletion was visualized using real-time confocal microscopy in a xenograft avian embryo model. We demonstrate the assessment of protein localization, cell morphology and migration in cells undergoing epithelial-mesenchymal and mesenchymal-epithelial transitions in breast tumors. This technique allows for precise control over protein activity in vivo while permitting the temporal analysis of dynamic biophysical parameters

Response-ability: Practicing integrity through intimacy in the marketplace

YesThe paper addresses the problem of pursuing ethical business practices purely under the aegis of ‘integrity’, as frequently used to characterise morally desirable traits. Drawing on the work of philosopher Thomas Kasulis, the paper pairs ‘integrity’ with ‘intimacy’ as a critical concept, placing greater attention upon relational properties, helping to understand ethics as existing between individuals, things and the environment. The argument is that by paying careful attention to spatial and temporal dynamics and proximities of exchange, businesses can better maintain and extend practices of integrity. It reminds us that ethics are developmental (not transcendental); that the cultivation of ethics provides greater depth and ownership and pertains to matters of the body and habits. The paper contributes a way of reading exchanges in the marketplace beyond prescriptive accounts of integrity. Through the lens of both integrity and intimacy, it identifies how we actually ‘live’ or practice greater responsiveness to exchanges

Lipid (per) oxidation in mitochondria:an emerging target in the ageing process?

Lipids are essential for physiological processes such as maintaining membrane integrity, providing a source of energy and acting as signalling molecules to control processes including cell proliferation, metabolism, inflammation and apoptosis. Disruption of lipid homeostasis can promote pathological changes that contribute towards biological ageing and age-related diseases. Several age-related diseases have been associated with altered lipid metabolism and an elevation in highly damaging lipid peroxidation products; the latter has been ascribed, at least in part, to mitochondrial dysfunction and elevated ROS formation. In addition, senescent cells, which are known to contribute significantly to age-related pathologies, are also associated with impaired mitochondrial function and changes in lipid metabolism. Therapeutic targeting of dysfunctional mitochondrial and pathological lipid metabolism is an emerging strategy for alleviating their negative impact during ageing and the progression to age-related diseases. Such therapies could include the use of drugs that prevent mitochondrial uncoupling, inhibit inflammatory lipid synthesis, modulate lipid transport or storage, reduce mitochondrial oxidative stress and eliminate senescent cells from tissues. In this review, we provide an overview of lipid structure and function, with emphasis on mitochondrial lipids and their potential for therapeutic targeting during ageing and age-related disease
