Das vorgestellte Forschungsprojekt will einen Beitrag leisten, Möglichkeiten wertorientierten Lernens im Geographieunterricht zu reflektieren. Mit der dokumentarischen Methode wird hier erstmals eine Forschungsmethode in einer geographiedidaktischen Studie eingesetzt, die angemessen komplex ist, das Feld des wertorientierten Lernens evaluativ zu erfassen. Dominieren hier bislang ausschließlich kognitive Forschungsansätze, so können mit der dokumentarischen Methode nicht nur explizite Bewertungen, sondern auch implizite Wertorientierungen methodisch kontrolliert rekonstruiert werden, um so adäquate Schlussfolgerungen für wertorientierten Geographieunterricht zu ziehen.

The study of maturation and spawning of the oyster is part of a research program to investigate the summer mortalities of the oysters, Crassostrea gigas in Marennes-Oléron Bay. Four maturity stages were simultaneously obtained by diet and thermal conditioning (immature, low maturation, mature and post-spawning stages). Measurements of clearance, filtration, absorption and respiration rates allowed a calculation of the scope for growth and hence an estimation of the oyster's energetic budget at various maturity stages. Male and female oysters had similar physiological responses. The filtration rate ranged from 2.4 to 2.6 1.h(-1) at the early stages of maturation and decreased to 1.8 1.h.' during the maturity stage. Growth rate resulting from gonad development did not induce filtration rate changes. Mature 2.5 and 1.5-year-old oysters showed a negative energy budget reaching -15 and -90 J.h(-1) respectively. By contrast, non-ripe oysters had scope for growth in the range 110 to 170 J.h(-1). A negative energy budget during the high maturation stage resulted from a reduced absorption efficiency. A new allometric relationship for the respiration model of C. gigas was defined during vitellogenesis with a 0.574 coefficient value. Based on Our results, the oyster's physiological weakness during vitellogenesis should be considered as a part of explanation for spring and summer mortalities of cultured oysters in Marennes-Oléron Bay.

Alcohol is one of the oldest and most widely used drugs on the planet, but the cellular mechanisms by which it affects neural function are still poorly understood. Unlike other drugs of abuse, alcohol has no specific receptor in the nervous system, but is believed to operate through GABAergic and serotonergic neurotransmitter systems. Invertebrate models offer circuits of reduced numerical complexity and involve the same cell types and neurotransmitter systems as vertebrate circuits. The well-understood neural circuits controlling crayfish escape behavior offer neurons that are modulated by GABAergic inhibition, thus making tail-flip circuitry an effective circuit model to study the cellular mechanisms of acute alcohol exposure. Crayfish are capable of two stereotyped, reflexive escape behaviors known as tail-flips that are controlled by two different pairs of giant interneurons, the lateral giants (LG) and the medial giants (MG). The LG circuit has been an established model in the neuroscience field for more than 60 years and is almost completely mapped out. In contrast, the MG is still poorly understood, but has important behavioral implications in social behavior and value-based decision making. In this dissertation, I show that both crayfish tail-flip circuitry are physiologically sensitive to relevant alcohol concentrations and that this sensitivity is observable on the single cell level. I also show that this ethyl alcohol (EtOH) sensitivity in the LG can be changed by altering the crayfish’s recent social experience and by removing descending inputs to the LG. While the MG exhibits similar physiological sensitivity, its inhibitory properties have never been studied before this research. Through the use of electrophysiological and pharmacological techniques, I show that the MG exhibits many similar inhibitory properties as the LG that appear to be the result of GABA-mediated chloride currents. Finally, I present evidence that the EtOH-induced changes in the MG are blocked through pre-treatment of the potent GABAA receptor agonist, muscimol, which underlines the role of GABA in EtOH’s effects on crayfish tail-flip circuitry. The work presented here opens the way for crayfish tail-flip circuitry to be used as an effective model for EtOH’s acute effects on aggression and value-based decision making.

Introducción: Siendo la desnutrición infantil, un indicador trazador en el perfil de salud de una población y prioridad establecida por los objetivos de desarrollo del milenio y el plan decenal de salud pública en Colombia - PDSP en su dimensión de seguridad alimentaria y nutricional, mantiene gran prevalencia a nivel nacional a pesar de presentar subregistro en la información reportada, por ende, es prioridad la medición, notificación y tratamiento de la misma. La OMS estandarizó los parámetros de medición y el gobierno nacional los adoptó mediante la resolución 2121 de 2010. Sin embargo, para disminuir el indicador de desnutrición que al año 2015 debería estar reducido en un 50% según el PDSP, es necesario identificar el sub registro que hay en el diagnóstico de la misma. Metodología: Se realizó un estudio poblacional, descriptivo y transversal, en el cual se analizó la base de datos de los niños menores de 5 años asistentes a consulta de crecimiento y desarrollo en una institución de salud del municipio de Puerto Inírida, con el fin de realizar una caracterización nutricional basados en mediciones antropométricas y contrastándolas realizadas por los profesionales de salud con las encontradas utilizando los patrones establecidos por la OMS. La información se analizó con el Software WHO Anthro propiedad de la OMS. Resultados: Se encontró que el 33,6% de los menores de 5 años registrados presentan desnutrición crónica, el 7,6% desnutrición aguda, el 13,2% de desnutrición global y el 13,9% tiene obesidad. Al discriminarlo por edad se encontró mayor prevalencia de desnutrición crónica en ambos sexos, siendo mayor en población de sexo masculino (40,1% masculino – 27,6% femenino); al igual que al realizar la comparación por pertenencia puesto que se encuentra la misma prevalencia en desnutrición crónica (29,1% en población indígena y 29% en población no indígena). Según los estándares de la OMS, en la población estudiada 12 se identificaron 243 casos de malnutrición, mientras que en la consulta de crecimiento y desarrollo fueron diagnosticados como casos de malnutrición por los profesionales de salud solo 99. Discusión: La malnutrición es un problema estructural, por ende, se deben tener en cuenta factores tanto intrínsecos como extrínsecos de la persona. Las medidas antropométricas son sólo una manera de medir, que se debe contextualizar con el entorno y las condiciones socioeconómicas, patológicas y culturales en las que se encuentre la población. El estado nutricional de los menores asistentes a los controles de crecimiento y desarrollo de la población estudiada, se encuentra mal registrado, de la misma manera se encontró una gran prevalencia de desnutrición crónica que es un determinante en la calidad de vida. Es imperante la implementación de políticas públicas adecuadas que permitan profundizar en las causas de este flagelo y así mismo en su tratamiento.

A lo largo del tiempo se aborda el liderazgo desde las posturas propias del comportamiento organizacional y la gestión humana. Desde un principio se basaba el liderazgo como un sujeto (líder), más adelante se tuvo en cuenta la parte situacional, es decir cómo afecta el entorno a la empresa y por último, es de principal interés el liderazgo organizacional. Dicho esto,en el contexto actual, un mundo globalizado y en que el mercado se vuelve más exigente, las organizaciones deben adaptarse y adecuarse rápidamente a los nuevos requerimientos para sobrevivir (Chiavenato, 2002) . Esta investigación tiene como fin explorar reconocer y demostrar como el mundo de los negocios es dinámico y exige cambiar para mejorar e incursionar estrategias que garanticen la perdurabilidad de una empresa, debido a esto se analizan diferentes empresas exitosas y perdurables en el tiempo ubicadas en la ciudad de Nueva York ,el cómo y porque la gestión humana, su talento humano en una organización debe ser valorado como personas dotadas de capacidades y habilidades que trabajan en conjunto por un bien común y así mismo ,la relación y el impacto que tiene con los diferentes estilos de liderazgos, por lo tanto ,si una compañía desea mostrarse y ser exitosa en el mercado, primeramente debe estar bien estructurada y fuerte por dentro , es decir, la relación directa con su talento humano.

La atención hospitalaria en el costo global de la atención de los pacientes en diálisis es muy importante. Este estudio se realizó con el fin de evaluar resultados posteriores a la implementación de un modelo de gestión de la enfermedad y cuidado coordinado en una red de diálisis en Colombia, evaluando los cambios específicos en las tasas de hospitalización de una cohorte de pacientes renales con dos años de seguimiento. El modelo se enfoca básicamente en mejorar la atención de los pacientes en diálisis protocolizando en el manejo de comorbilidades (diabetes, riesgo cardiovascular, patologías infecciosas) y en el cuidado coordinado entre el tratamiento ambulatorio y hospitalario de los pacientes en diálisis asegurando la continuidad en el proceso de atención de los pacientes. El Estudio observacional analítico de cohortes compuesto por 2 fases una primera cohorte histórica retrospectiva y una segunda con dos cohortes prospectivas, incluyó pacientes mayores de 18 años, con más de 90 días en diálisis, con al menos tres meses de intervención con el modelo de gestión de enfermedad en la red Renal Therapy Services (RTS®). En conclusión, la realización de este estudio, se pudo asociar a la reducción en la atención hospitalaria de pacientes en diálisis y a una menor mortalidad, modelos como este y otras soluciones para mejorar los desenlaces en salud en los pacientes en diálisis deben seguir siendo implementados para aliviar la carga de la enfermedad y reducir los costos de la atención en salud de esta población.

Los estudios de liderazgo han abordado la interacción que existe entre el sujeto denominado líder y sus seguidores. Dentro de dicha relación se han estudiado las habilidades del líder y su impacto como coach. Hoy en día se pueden evidenciar un sinnúmero de estudios y aproximaciones en torno al término coaching, concepto, marcos teóricos, modelos, etc… En el presente artículo se hará un proceso investigativo en el que se define coaching desde el punto de vista de varios autores, expertos y managers que se desarrollan en el ámbito empresarial para poder encontrar una definición que comprenda las dimensiones del mundo organizacional, A continuación, se hará una búsqueda sistemática de las definiciones de coaching y a partir de esta búsqueda se propondrá una definición integradora que dé cuenta de los diversos ámbitos del estudio del liderazgo. Al revisar la terminología en cuanto a liderazgo y coaching, junto con su relación directa no hay una definición que realmente abarque todo el tema organizacional que implica estas dos palabras.

This monograph outlines the process and results of development of a common educational programme at masters level in health and social care management, which was supported by the Erasmus Life Long Education project CareMan (Cul- ture and Care Management). The CareMan project brought together university partners actively involved in educating social and health care professionals in leadership and management at master’s level in Europe. The five partners of the consortium were Lahti University of Applied Sciences – Lahti UAS (administra- tive and academic coordinator, Finland), Charles University – CU (the Czech Republic), Edinburgh Napier University – ENU (Scotland), Hammeline University of Applied Sciences – HAMK (Finland), and University of Évora – UoE (Portugal). The objectives of the project were to achieve lower -level educational goals that included the development through education cultural and value -driven leadership, quality of care and quality management to effectively manage an integrated health and social care service. Through mapping the situation in the field and comparing curricula of all participating universities the overall aim was to develop a joint masters programme in social and healthcare management. After the detailed understanding of national and institutional specifics of each of the individual academic entities it was recognised that, due to a number of regulation issues, the original aim was not achievable. Following subsequent analytical work, it was decided to develop a set of three master’s level modules. At the end of the project it was intended that all created modules would be available virtually to the participating programmes and would contribute some added value to existing curricula. In the future these ready -to -use modules are intended to be taught in cooperation with the participating universities or as a separate module in each university. The chosen theoretical framework of the project that underpinned the devel- opment, management and evaluation of the inter -cultural educational provision relied on the combination of two learning theories – ‘cooperative collaborative and social learning’ and ’transformational’ (Mezirow, 2009). This theoretical framework helped to align with European collaborative policy and its application on all levels of implementation of the project.

Global challenges, complexity and continuous uncertainty demand development of leadership approaches, employees and multi-organisation constellations. Current leadership theories do not sufficiently address the needs of complex business environments. First of all, before successful leadership models can be applied in practice, leadership needs to shift from the industrial age to the knowledge era. Many leadership models still view leadership solely through the perspective of linear process thinking. In addition, there is not enough knowledge or experience in applying these newer models in practice. Leadership theories continue to be based on the assumption that leaders possess or have access to all the relevant knowledge and capabilities to decide future directions without external advice. In many companies, however, the workforce consists of skilled professionals whose work and related interfaces are so challenging that the leaders cannot grasp all the linked viewpoints and cross-impacts alone. One of the main objectives of this study is to understand how to support participants in organisations and their stakeholders to, through practice-based innovation processes, confront various environments. Another aim is to find effective ways of recognising and reacting to diverse contexts, so companies and other stakeholders are better able to link to knowledge flows and shared value creation processes in advancing joint value to their customers. The main research question of this dissertation is, then, to seek understanding of how to enhance leadership in complex environments. The dissertation can, on the whole, be characterised as a qualitative multiple-case study. The research questions and objectives were investigated through six studies published in international scientific journals. The main methods applied were interviews, action research and a survey. The empirical focus was on Finnish companies, and the research questions were examined in various organisations at the top levels (leaders and managers) and bottom levels (employees) in the context of collaboration between organisations and cooperation between case companies and their client organisations. However, the emphasis of the analysis is the internal and external aspects of organisations, which are conducted in practice-based innovation processes. The results of this study suggest that the Cynefin framework, complexity leadership theory and transformational leadership represent theoretical models applicable to developing leadership through practice-based innovation. In and of themselves, they all support confronting contemporary challenges, but an implementable method for organisations may be constructed by assimilating them into practice-based innovation processes. Recognition of diverse environments, their various contexts and roles in the activities and collaboration of organisations and their interest groups is ever-more important to achieving better interaction in which a strategic or formal status may be bypassed. In innovation processes, it is not necessarily the leader who is in possession of the essential knowledge; thus, it is the role of leadership to offer methods and arenas where different actors may generate advances. Enabling and supporting continuous interaction and integrated knowledge flows is of crucial importance, to achieve emergence of innovations in the activities of organisations and various forms of collaboration. The main contribution of this dissertation relates to applying these new conceptual models in practice. Empirical evidence on the relevance of different leadership roles in practice-based innovation processes in Finnish companies is another valuable contribution. Finally, the dissertation sheds light on the significance of combining complexity science with leadership and innovation theories in research.

In this second counterpoint article, we refute the claims of Landy, Locke, and Conte, and make the more specific case for our perspective, which is that ability-based models of emotional intelligence have value to add in the domain of organizational psychology. In this article, we address remaining issues, such as general concerns about the tenor and tone of the debates on this topic, a tendency for detractors to collapse across emotional intelligence models when reviewing the evidence and making judgments, and subsequent penchant to thereby discount all models, including the ability-based one, as lacking validity. We specifically refute the following three claims from our critics with the most recent empirically based evidence: (1) emotional intelligence is dominated by opportunistic academics-turned-consultants who have amassed much fame and fortune based on a concept that is shabby science at best; (2) the measurement of emotional intelligence is grounded in unstable, psychometrically flawed instruments, which have not demonstrated appropriate discriminant and predictive validity to warrant/justify their use; and (3) there is weak empirical evidence that emotional intelligence is related to anything of importance in organizations. We thus end with an overview of the empirical evidence supporting the role of emotional intelligence in organizational and social behavior.

This paper reports a comparative study of Australian and New Zealand leadership attributes, based on the GLOBE (Global Leadership and Organizational Behavior Effectiveness) program. Responses from 344 Australian managers and 184 New Zealand managers in three industries were analyzed using exploratory and confirmatory factor analysis. Results supported some of the etic leadership dimensions identified in the GLOBE study, but also found some emic dimensions of leadership for each country. An interesting finding of the study was that the New Zealand data fitted the Australian model, but not vice versa, suggesting asymmetric perceptions of leadership in the two countries.

Species distribution models (SDMs) studies suggest that, without control measures, the distribution of many alien invasive plant species (AIS) will increase under climate and land-use changes. Due to limited resources and large areas colonised by invaders, management and monitoring resources must be prioritised. Choices depend on the conservation value of the invaded areas and can be guided by SDM predictions. Here, we use a hierarchical SDM framework, complemented by connectivity analysis of AIS distributions, to evaluate current and future conflicts between AIS and high conservation value areas. We illustrate the framework with three Australian wattle (Acacia) species and patterns of conservation value in Northern Portugal. Results show that protected areas will likely suffer higher pressure from all three Acacia species under future climatic conditions. Due to this higher predicted conflict in protected areas, management might be prioritised for Acacia dealbata and Acacia melanoxylon. Connectivity of AIS suitable areas inside protected areas is currently lower than across the full study area, but this would change under future environmental conditions. Coupled SDM and connectivity analysis can support resource prioritisation for anticipation and monitoring of AIS impacts. However, further tests of this framework over a wide range of regions and organisms are still required before wide application.

One major goal of research on Chagas disease is the development of effective chemotherapy to eliminate the infection from individuals who have not yet developed cardiac and/or digestive disease manifestations. Cure evaluation is the more complex aspect of its treatment, often leading to diverse and controversial results. The absence of reliable methods or a diagnostic gold standard to assess etiologic treatment efficacy still constitutes a major challenge. In an effort to develop more sensitive tools, polymerase chain reaction (PCR)-based assays were introduced to detect low amounts of Trypanosoma cruzi DNA in blood samples from chagasic patients, thus improving the diagnosis and follow-up evaluation after chemotherapy. In this article, I review the main problems concerning drug efficacy and criteria used for cure estimation in treated chagasic patients, and the work conducted by different groups on developing PCR methodologies to monitor treatment outcome of congenital infections as well as recent and late chronic T. cruzi infections.
