Report on Lake Wamala fisheries catch assessment survey 2012

Lake Wamala is one of the small lakes in Uganda, and lies between latitudes 0o 15; and 0o 25' N 31o 45' to longitude 32o 00' E, longitude and at an altitude of 1000m above sea level. Following ths 1961 heavy rains the lake expanded from about 100 to 118 sq. km and the swamps covered almost 60 sq km (Okaranon 1993). This lake was first stocked with Oreohromis niloticus eduardianus populary known as Oreohromis niloticus then Oreochromis leucostictus and then Tilapia zillii then after that it was officially opened for commercial fishing in 1960. Despite of the commercial fishery there used to be subsistance fishing that was mainly by the use of wires and hooks and targeted the Clarias and Protopterus species. The lake fishery used to be highly profitable after the opening in 1960; though in 1970s the fishers started complaining of the declining state of the fishery. At that time the O. niloticus had gone down to less than 1 kg per net per night by 1975 (Okaranon 1993). Due to it led to scientists undertake fisheries surveys in 1975/78 and later 1988/92 then later on there subsquent survey in 2003. Since that time there has been no work done until March 2012 that both catch assessment and frame surveys undertaken to ensure that management issues are addressed concerning this riparian water body. The main objectives of the survey were:- To assess fish production levels in the commercial fisheries of Lake Wamala (Catch Assessment). To assess the fishing effort and facilities available at the fish landings that supports the fisher folks.

Developing an integrated hydrograph separation and lumped modelling approach to quantifying hydrological pathways in Irish river catchments

An appreciation of the quantity of streamflow derived from the main hydrological pathways involved in transporting diffuse contaminants is critical when addressing a wide range of water resource management issues. In order to assess hydrological pathway contributions to streams, it is necessary to provide feasible upper and lower bounds for flows in each pathway. An important first step in this process is to provide reliable estimates of the slower responding groundwater pathways and subsequently the quicker overland and interflow pathways. This paper investigates the effectiveness of a multi-faceted approach applying different hydrograph separation techniques, supplemented by lumped hydrological modelling, for calculating the Baseflow Index (BFI), for the development of an integrated approach to hydrograph separation. A semi-distributed, lumped and deterministic rainfall runoff model known as NAM has been applied to ten catchments (ranging from 5 to 699 km2). While this modelling approach is useful as a validation method, NAM itself is also an important tool for investigation. These separation techniques provide a large variation in BFI, a difference of 0.741 predicted for BFI in a catchment with the less reliable fixed and sliding interval methods and local minima turning point methods included. This variation is reduced to 0.167 with these methods omitted. The Boughton and Eckhardt algorithms, while quite subjective in their use, provide quick and easily implemented approaches for obtaining physically realistic hydrograph separations. It is observed that while the different separation techniques give varying BFI values for each of the catchments, a recharge coefficient approach developed in Ireland, when applied in conjunction with the Master recession Curve Tabulation method, predict estimates in agreement with those obtained using the NAM model, and these estimates are also consistent with the study catchments’ geology. These two separation methods, in conjunction with the NAM model, were selected to form an integrated approach to assessing BFI in catchments.

Serving Multiple Masters: Exploring HRD in the Context of Third Sector Partnerships for Public Service Delivery

Organisations in the Non-Profit and Voluntary (NPV) sector increasingly face challenging and uncertain times with an increasing shift from public grant funding towards contract funding. As a result many of these changes employees in such organisations have often found themselves working more closely under contract with colleagues in public sector organisations in order to provide public services. Using a multiple case study methodology and in-depth interviewing of a range of stakeholders form two large Northern Irish based Non Profit Organisations in the social care sector, the purpose of this research was to
investigate HRD and people management issues and how a turbulent environment can affect how organisations approach HRD strategy and implementation.

The research identifies the importance placed upon NPOs adopting HRD strategies and addressing the development of unique and specialised skills in order to claw back power within the relationships they serve with statutory funding bodies. However this research also notes that the manner in which HRD and its associated issues are considered within NPOs can have an impact on the loyalty and commitment of the workforce which serves them. What is of concern is that the context for the delivery of public services under contract is putting increasing strain on NPOs and this has been felt markedly by their respective workforces, and unless strong values-led leadership and managerial practice is in
place in NPOs, the voluntary-centred ethos of those who work in the sector may be significantly damaged.

Intra-testicular varicocele presenting as acute scrotum

The term varicocele describes a dilated, tortuous and elongated pampiniform plexus of veins, which is well known in relation to the spermatic cord. Recently varicocele has also been observed inside the testis, and this new entity is known as intra-testicular varicocele. We present a case of intra-testicular varicocele presenting as acute scrotum and discuss the management issues.

Gene-associated markers can assign origin in a weakly structured fish, Atlantic herring

Regulations on the exploitation of populations of commercially important fish species and the ensuing consumer interest in sustainable products have increased the need to accurately identify the population of origin of fish and fish products. Although genomics-based tools have proven highly useful, there are relatively few examples in marine fish displaying accurate origin assignment. We synthesize data for 156 single-nucleotide polymorphisms typed in 1039 herring, Clupea harengus L., spanning the Northeast Atlantic to develop a tool that allows assignment of individual herring to their regional origin. We show the method's suitability to address specific biological questions, as well as management applications. We analyse temporally replicated collections from two areas, the Skagerrak (n = 81, 84, 66) and the western Baltic (n = 52, 52). Both areas harbour heavily fished mixed-origin stocks, complicating management issues. We report novel genetic evidence that herring from the Baltic Sea contribute to catches in the North Sea, and find support that western Baltic feeding aggregations mainly constitute herring from the western Baltic with contributions from the Eastern Baltic. Our study describes a general approach and outlines a database allowing individual assignment and traceability of herring across a large part of its East Atlantic distribution.

Effects of nutrient and light enrichment on phytoplankton growth

Alterations of freshwater flow regimes and increasing eutrophication lead to alterations in light availability and nutrient loading into adjacent estuaries and coastal areas. Phytoplankton community respond to these changes in many ways. Harmful phytoplankton blooms, for instance, may be a consequence of changes in nutrient supply, as well as the replacement of some phytoplankton species (like diatoms, that contribute for the development of large fish and shellfish populations) by ohers (like cyanobacteria, that may be toxic and represent an undesirable food source for higher trophic levels). Nutrient and light enrichment experiments allow us to understand and predict the effects of eutrophication on the growth of phytoplankton. This is a fundamental tool in water management issues, since it enables the prediction of changes in the phytoplankton community that may be harmful to the whole ecosystem, and the design of mitigation strategies (Zalewski 2000).

In Search of Corporate Renewal: How to Benefit from Corporate Venturing?

Despite the rapid change in today's business environment there are relatively few studies about corporate renewal. This study aims for its part at filling that research gap by studying the concepts of strategy, corporate renewal, innovation and corporate venturing. Its purpose is to enhance our understanding of how established companies operating in dynamic and global environment can benefit from their corporate venturing activities. The theoretical part approaches the research problem in corporate and venture levels. Firstly, it focuses on mapping the determinants of strategy and suggests using industry, location, resources, knowledge, structure and culture, market, technology and business model to assess the environment and using these determinants to optimize speed and magnitude of change.Secondly, it concludes that the choice of innovation strategy is dependent on the type and dimensions of innovation and suggests assessing market, technology, business model as well as novelty and complexity related to each of them for choosing an optimal context for developing innovations further. Thirdly, it directsattention on processes through which corporate renewal takes place. On corporate level these processes are identified as strategy formulation, strategy formation and strategy implementation. On the venture level the renewal processes are identified as learning, leveraging and nesting. The theoretical contribution of this study, the framework of strategic corporate venturing, joins corporate and venture level management issues together and concludes that strategy processes and linking processes are the mechanism through which continuous corporate renewaltakes place. The framework of strategic corporate venturing proposed by this study is a new way to illustrate the role of corporate venturing as a purposefullybuilt, different view of a company's business environment. The empirical part extended the framework by enhancing our understanding of the link between corporate renewal and corporate venturing in its real life environment in three Finnish companies: Metso, Nokia and TeliaSonera. Characterizing companies' environmentwith the determinants of strategy identified in this study provided a structured way to analyze their competitive position and renewal challenges that they arefacing. More importantly the case studies confirmed that a link between corporate renewal and corporate venturing exists and found out that the link is not as straight forward as indicated by the theory. Furthermore, the case studies enhanced the framework by indicating a sequence according to which the processes work. Firstly, the induced strategy processes strategy formulation and strategy implementation set the scene for corporate venturing context and management processes and leave strategy formation for the venture. Only after that can strategies formed by ventures come back to the corporate level - and if found viable in the corporate level be formalized through formulation and implementation. With the help of the framework of strategic corporate venturing the link between corporaterenewal and corporate venturing can be found and managed. The suggested response to the continuous need for change is continuous renewal i.e. institutionalizing corporate renewal in the strategy processes of the company. As far as benefiting from venturing is concerned the answer lies in deliberately managing venturing in a context different to the mainstream businesses and establishing efficientlinking processes to exploit the renewal potential of individual ventures.

Réintroduire la multifonctionnalité des paysages en zone d’intensification agricole : contribution des approches intégrées en écologie du paysage

Depuis l’avènement de l’agriculture productiviste, les paysages des zones d’intensification agricole des pays industrialisés ont été marqués par la perte sévère de leur diversité et la dégradation de leurs fonctions environnementales, récréatives, esthétiques et sociales. Au moment où la qualité des paysages constitue un facteur clé du dynamisme des collectivités rurales, il devient urgent de développer des stratégies d’aménagement aptes à réintroduire le caractère multifonctionnel de ces paysages. Dans ce contexte, cette thèse propose un éclairage sur les enjeux d’aménagement de ces paysages sous l’angle des approches dialectiques en paysage issues de la Holistic Landscape Ecology. En développant un modèle conceptuel des trajectoires des paysages s’inscrivant dans les approches intégrées en paysage, elle établit une double lecture des dynamiques physico-spatiale et socioculturelle des paysages des zones d’intensification agricole afin d’en arriver à qualifier les écarts entre celles-ci. Pour y parvenir, elle prend appui sur une étude de cas d’un bassin versant agricole du sud du Québec. En puisant tantôt dans l’écologie du paysage, tantôt dans la sociologie du paysage, les résultats de cette thèse soulignent d’une part le poids des forces politiques et économiques dans le façonnement de ces paysages. Mais ils révèlent également le rôle des valorisations paysagères des agriculteurs dans la modulation de ces forces. Plus encore, l’étude des dynamiques socioculturelles révèle une diversité au sein des populations locales au plan des valorisations de ces paysages et des pratiques qui les façonnent qui vient renouveler l’image d’uniformité de ces territoires. Le maintien et l’accentuation de cette diversité apparaissent susceptibles de contribuer significativement à la réintroduction du caractère multifonctionnel des paysages au sein des zones d’intensification agricole. Des pistes concrètes pour l’aménagement concluent cette thèse.

Considérer l’expérience du visiteur, une clé pour la gestion intégrée des forêts

Les forêts occidentales sont aujourd’hui de plus en plus prisées pour la pratique d’activités récréatives en milieu naturel. Dès lors, la mise en place d’une gestion intégrée des forêts est plus que jamais indispensable au maintien des conditions nécessaires à la pratique de l’ensemble des activités sur le territoire. Le Québec s’est doté d’une nouvelle législation pour répondre aux nombreux enjeux qui touchent le milieu forestier, notamment en ce qui a trait à l’harmonisation entre les activités récréatives et la production ligneuse. Dans le cadre de cette recherche, nous nous sommes intéressés au concept d’expérience du visiteur comme moyen de faciliter cette harmonisation. Il s’agissait à la fois de caractériser l’expérience de visite des utilisateurs d’un parc régional et de se questionner sur son opérationnalisation dans l’aménagement forestier. Deux méthodes qualitatives complémentaires ont été utilisées : d’une part, l’analyse de récits inscrits dans des livres d’or placés dans différents hébergements et d’autre part, des entrevues ont été conduites auprès de visiteurs rencontrés sur le site. Les résultats révèlent la pertinence de considérer l’expérience du visiteur pour favoriser une utilisation plurielle et harmonieuse du territoire forestier. Son étude permet une compréhension fine des composantes communes et spécifiques des expériences, en fonction des visiteurs. Par ailleurs, l’étude témoigne de la possibilité de mettre en relation des typologies d’expériences recherchées et les modalités d’harmonisation. Enfin, au-delà de l’expérience, le suivi de la perception de la foresterie et des représentations peut également s’avérer pertinent pour les gestionnaires.

Teoría de restricciones aplicada a la dirección administrativa y financiera de la escuela de medicina y ciencias de la salud de la universidad del rosario

La creación de la Escuela de Medicina y Ciencias de la Salud en la Universidad del Rosario el 1 de julio de 2009 generó la necesidad de apoyar un mayor número de profesores e investigadores en temas administrativos, financieros y jurídicos. Para ello fue necesaria la contratación de una coordinadora administrativa y una coordinadora financiera para que la gestión de la Dirección Administrativa y Financiera pudiera cumplir con el apoyo a la Academia. Sin embargo, la gestión jurídica que soporta los proyectos de Investigación, Asesoría y Consultoría de la Escuela de Medicina y Ciencias de la Salud no era lo suficientemente ágil frente a las necesidades de respuesta a los patrocinadores externos. Por lo tanto, por medio de la aplicación de la Teoría de Restricciones, construcción de nubes de conflictos, encuestas a los investigadores y desarrollo de un formulario como herramienta en el Sistema de Información SAP, se agilizó el proceso de la Oficina Jurídica no solo para los procesos de la Escuela de Medicina y Ciencias de la Salid sino para todas la facultades y dependencias de la Universidad del Rosario

De la morbilidad a la perdurabilidad : productos 3A

El entorno económico actual se caracteriza por su dinamismo. Las diferentes tendencias hacen del entorno un medio altamente competitivo, inestable y cambiante lo que fomenta mayor liderazgo en las empresas que deseen perdurar y alcanzar el éxito. Solo aquellas empresas que logran adaptarse a los diferentes cambios podrán sobrevivir a la incertidumbre y la complejidad. Es innegable que en un momento dado se haga presente una crisis que pueda alterar el funcionamiento normal de las empresas y en algunos casos sentirse al borde de la muerte; sin embargo cuando las crisis son superadas, se ve reflejado la perseverancia y el esfuerzo estratégico realizado por el director y su equipo de trabajo. Es el caso de Productos 3A, empresa Colombiana dedicada a la industria de alimentos, importando, comercializando y distribuyendo principalmente frutos deshidratados; que sobrellevó una crisis iniciada en 1999 debido principalmente a la situación financiera que esta tuvo que enfrentar por su alto nivel de endeudamiento. A través del tiempo logro implementar diferentes estrategias que fueron fundamentales para su supervivencia, entre las cuales se encontraban acogerse a la ley 550, además de trabajar y mejorar en aspectos de dirección y gerencia; logrando así posicionarse en el mercado Colombiano, convirtiéndose en uno de los primeros importadores a nivel nacional de frutos deshidratados. Finalmente, la facultad de Administración de la Universidad del Rosario, en cooperación con la Superintendencia de Sociedades, otorga cada año el Premio Ave Fénix, en reconocimiento a las empresas que habiendo iniciado un proceso de liquidación, resurgen y generan resultados favorables, sostenibles y perdurables en el tiempo. La empresa Productos 3A obtiene este reconocimiento producto de su esfuerzo, resiliencia y perseverancia, convirtiéndose en un gran ejemplo en el campo empresarial de que es posible saltar de la morbilidad a la perdurabilidad.

Calidad de vida en personas con hemofilia: una revisión de la literatura

Introducción: La hemofilia es una enfermedad poco frecuente; no obstante, los avances en los tratamientos de pacientes hemofílicos en las últimas décadas han generado cambios en su calidad de vida. Esto ha motivado el desarrollo de múltiples investigaciones al respecto. Objetivo: Revisar la literatura sobre la calidad de vida en el paciente hemofílico, producida en el periodo 2008-2012. Método: Se consultaron algunas bases de datos científicas utilizando como palabras clave “hemofilia” y “calidad de vida”. Se recopiló la información encontrada y se organizó según los objetivos propuestos en “factores negativos” y “factores protectores” de la calidad de vida a nivel fisiológico, psicosocial y cultural; “instrumentos para la evaluación de la calidad de vida” a nivel específico y general; y antecedentes empíricos de los últimos cinco años en los que se evaluara la calidad de vida o se realizara alguna intervención en la misma. Resultados: En general la información disponible sobre el comportamiento epidemiológico de la hemofilia es limitada. El interés por factores protectores y negativos es principalmente de tipo fisiológico, aunque se encontraron factores de tipo psicosocial y cultural, lo que indica la importancia de profundizar en esta temática. Existen pocos instrumentos especializados para la evaluación de la calidad de vida en hemofílicos. La evidencia empírica se centra en la evaluación. Conclusión: El estudio de la calidad de vida en pacientes hemofílicos amerita ser abordado de manera interdisciplinaria.
