Uppföljning och utvärdering av det balanserade styrkortet : Är balanserat styrkort ett värdeskapande och strategiskt instrument inom den kommunala verksamheten?

The need to steer economic development has always been great and as management model has the balanced scorecard has been popular since the mid- 1990s, mainly in the private sector but also in the municipal sector. The introduction of the balanced scorecard has been primarily to organizations to see more than economic dimensions. The Balanced Scorecard was originally a measurement system, and today it works more as a strategic instrument. In our study is a case study to evaluate a municipality and how they make use of the balanced scorecard as a tool for strategic and value-adding work in municipal activities. In the local business is it important that the organization adapts the balanced scorecard, so it fits on the basis that it is a politically driven organization, with mandates, committees and administrations. In our study, we used a qualitative method with a deductive approach. In the study, we have gathered information through a case study where we interviewed 7 people in leading positions. In our analysis and results section, we came to the conclusion that the municipality does not use the balanced scorecard correctly. We also found that the balanced scorecard as a tool for value creation and strategic planning does not work in a favorable way. In our study, we see difficulties with the implementation of the balanced scorecard. If the municipality has invested in implementing the balanced scorecard at all levels of the business so the municipality would be able to use it on one of the activities more adequately. When the municipality is a politically driven organization, it is important that vision alive and changing based on the conditions that reflect the outside world and the municipality in general. Looking at a vivid vision, goals and business ideas, it's balanced scorecard in line with how a balanced scorecard should look like. The municipality has a strategic plan in terms of staff and employees at large. In the study, we have seen that the strategic plan is not followed up in a good way and for the business favorably, the municipality chooses the easy way out for evaluation. Employee participation to changes and ongoing human resources management feels nonexistent. However, as has been the vision of creating empowered and motivated employees. In our conclusion, we describe how we in our study look at the use of the balanced scorecard in municipal operations. We can also discern that a balanced scorecard as a tool for value creation and strategic work is good if it is used properly. In the study, we have concluded that the municipality we have chosen to study should not use the balanced scorecard when you have not created the tools and platforms required for employees, civil servants and politicians to evaluate, monitor and create a living scorecard change over time. The study reveals major shortcomings in the implementation, evaluation and follow-up possibilities, and the consequence of this is that the balanced scorecard is not - 4 - preferable in municipal operations as a strategic instrument for value creation and long-term planning.

Identification of 1-methyloctyl butanoate as the major sex pheromone component from females of the saddle gall midge, Haplodiplosis marginata (Diptera: Cecidomyiidae)

The saddle gall midge, Haplodiplosis marginata (von Roser) (Diptera: Cecidomyiidae), has undergone a resurgence recently as a pest of cereals in Belgium and other European countries. An effective monitoring tool of saddle gall midge flights is needed to understand the enigmatic population dynamics of this pest, and to design an integrated management strategy. Therefore, volatile compounds emitted by females (alkan-2-ols and alk-2-yl butanoates) were identified, and the chirality of the emitted esters was determined to be the R absolute configuration. In field-trapping experiments, racemic non-2-yl butanoate attracted substantial numbers of H.marginata males. Thus, this compound will be useful in baited traps for monitoring seasonal flight patterns, and improving integrated management of the saddle gall midge in agricultural systems.

Effects of shrimp pond water on phytoplankton: importance of salinity and trophic status of the receiving environment

Aquaculture generates a large load of effluents richin organic matter and nutrients that may be intro-duced into the environment. This study aimed toassess in a microcosm experiment, the effect ofshrimp pond water mixed with Patos Lagoon estuarywater on phytoplankton chlorophyll a and primaryproduction, simulating two salinities. Chlorophyll a,dissolved inorganic nutrients and primary produc-tion were measured in two experiments. In Harvest I,salinity of shrimp pond and environment water wassimilar, and chlorophyll a showed different trendsover time, according to the amount of nitrogen avail-able. In Harvest II, with different salinities and highnutrient concentrations in environment water, chlo-rophyll a levels showed a similar increasing trendover time in all mixtures. Net primary productionshowed differences among treatments in the firstsampling in Harvest I, but not in the second, whereasno differences were observed among treatments inHarvest II. We conclude that shrimp pond effluentcan lead to short-term variations in chlorophyll aand primary production levels, with similar salinities.Salinity differences result in lower chlorophyll a andprimary production values than expected accordingto the nutrient input. Differences in salinity can bean important management strategy to choose thebest harvest period.

Altura do pasto e adubação nitrogenada sobre a produção de forragem e eficiência no uso de nutrientes em sistema de integração lavoura-pecuária

The proper use of management strategies, such as grazing intensity and nitrogen fertilization are primordial to the success of integrated crop-livestock system. Several studies have demonstrated the influence of grazing intensity and nitrogen fertilization on dynamics of forage production and nutrient cycling. However, most this researches studying these strategies in isolation and little is known about the interaction of these factors in the management of an integrated crop-livestock system. In this context, the aim of this study is to determine the best management strategy involving sward height and nitrogen fertilization, permitting greater forage production and improved efficiency in the use of nitrogen soil by a black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture in integrated crop-livestock system. The experiment was realized in Abelardo Luz – SC, in an area of 14 ha, where has been conducted an experiment in long term with integrated crop-livestock system under no-tillage since 2012. The experimental design is a randomized block design with three replications in a factorial design (2x2), the first factor was the grazing intensity (high and low), characterized by two sward height management (10 and 25 cm), and the second included the time factor application of N in the system: N applied on pasture (N-pasture) and N applied on the culture of grain (N-grain), at dose of 200 kg N ha stocking and variable stocking rate. The previous crop to pasture was corn. The nitrogen fertilization of pasture increased tiller density, forage density, participation of ryegrass ‘Barjumbo’ and percentage of ryegrass leaves in forage mass. Forage mass was less at low sward height on average, however the percentage of ryegrass ‘Barjumbo’ and rye leaves was greater and dead material was lower in this treatment. With nitrogen fertilization of pasture it was possible to double the amount of forage accumulated in periods with further development of ryegrass, furthermore, the total production of DM was increased in 38.4% and the shoot N concentration in 28.6%. When the nitrogen fertilization is applied in pasture, it is possible to keep black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture with an average sward height of 11 cm. The residual effect of N applied at corn was not sufficient to meet the nutritional needs of pasture and the forage production was affected by periods with N deficiency, while a single application of 200 kg N ha was sufficient to meet the N requirements throughout the forage accumulation period. The black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture is efficient in use and recovery of the nitrogen applied in both treatments of sward height.

FERTILISER CREDIT AND AGROECOLOGICAL USE OF ORGANIC SOIL AMENDMENTS IN NORTHERN GHANA

Contemporary African agricultural policy embodies the African Green Revolution’s drive towards modernisation and commercialisation. Agroecologists have criticised this movement on ecological, social and political grounds. Northern Ghanaian fertiliser credit schemes provide a good example through which these critiques can be examined in a context where agricultural policy reflects the African Green Revolution’s ideals. This study aimed to determine the relationship of such credit schemes to farmers’ use of organic amendments, elucidate other factors related to organic amendment use, and comment on the relevance of this modernisation policy and its relationship to agroecology. A first research phase employed semi-structured key informant interviews. Qualitative data from these informed construction of a semi-structured questionnaire that was used in a survey of 205 farmers. Multistage sampling purposively identified five villages and selected farmers within who had joined government and donor-funded fertiliser credit schemes. The use of organic and inorganic amendments was compared to that of peers who had not taken part in such schemes. Quantitative data were used in binomial logistic regression, inferential and descriptive statistics. Qualitative data were content analysed. Credit group membership was associated with higher fertiliser application and yield, but had little influence on the extent of commercialisation. Farmers who applied organic amendments were 40% less likely to belong to a fertiliser credit scheme than not, indicating substitution between organic and inorganic fertilisers. Organic amendments were 40% more likely to be applied to compound farms than outfields and six times more likely to be applied by household heads than other household members. However, household heads also preferentially joined credit groups. This was part of an agroecological soil fertility management strategy. Household heads appreciated the soil moisture retention properties of organic amendments, and applied them to compound farms to reduce risk to their household food supply in a semi-arid environment. They simultaneously accessed fertiliser to enhance this household provisioning strategy. They appreciated the increased yields this achieved, yet complained that the repayment terms of credit schemes were unfair, fertiliser did not enhance yields in dry conditions and fertilisers were supplied late. Farmers’ use of credited fertiliser alongside their existing agroecological strategy is helpful to the extent that it raises yields, yet is problematic in that it conflicts with risk-reduction strategies based on organics. There is some potential for modernised and agroecological management paradigms to coexist. For fertiliser credit to play a role in this, schemes must use fairer repayment terms and involve a focus on simultaneous use of organic amendments.

Managing Fisheries in the context of an integrated policy: the importance of spatial issues

A variety of conservation policies now frame the management of fishing activity and so do also the spatial planning of different sectorial activities. These framework policies are additional to classical fishery management. There is a risk that the policies applying on the marine system are not coherent from a fisheries point of view. The spatial management of fishing activity at regional scale has the potential to meet multiple management objectives, on a habitat basis. Here we consider how to integrate multiple objectives of different policies into integrated ocean management scenarios. In the EU, European Directives and the CFP are now implementing the ecosystem approach to the management of human activity at sea. In this context, we further identify three research needs: • Develop Management Strategy Evaluation (MSE) for multiple-objective and multiple-sector spatial management schemes • Improve knowledge on and evaluation of functional habitats • Develop spatially-explicit end-to-end models with appropriate complexity for spatial MSE The contribution is based on the results of a workshop of the EraNet COFASP.

Avaliação do desempenho numa organização desportiva : o balanced scorecard adaptado às piscinas da Associação Humanitária de Bombeiros Voluntários de Colares

A gestão de uma organização, independentemente da sua natureza, representa na atualidade um grande desafio. Inicialmente, o sucesso no desenvolvimento do processo de gestão de uma organização depende, essencialmente, de uma estratégia bem formulada e implementada, mas no entanto, a longo prazo, este êxito só será possível se existir um mecanismo de monitorização que permita realizar ao longo do tempo uma avaliação do desempenho. O Balanced Scorecard (BSC), da autoria de Robert Kaplan e David Norton, na década de 90, surgiu inicialmente como uma metodologia de avaliação do desempenho e rapidamente começou a ser utlizado também como um sistema de gestão estratégica. Esta ferramenta pode ser utilizada nos mais variados tipos de organizações visto que pode ser adaptada às características e especificidades de cada uma. O presente estudo tem como objetivo adaptar o Balanced Scorecard a uma organização desportiva, as Piscinas da Associação Humanitária de Bombeiros Voluntários de Colares, de modo que, relativamente à metodologia empregue, este consiste num estudo de caso. Com o objetivo de suportar o estudo de uma forma coerente, foram utilizados como instrumentos de recolha de dados um conjunto de entrevistas e a análise documental. Como principal conclusão deste estudo retiramos que o BSC é de facto uma ferramenta muito útil para desenvolver a estratégia de uma organização e avaliar o seu desempenho.

Influence of Soil Biogeochemical Properties on the Invasiveness of Old World Climbing Fern (Lygodium microphyllum)

The state of Florida has one of the most severe exotic species invasion problems in the United States, but little is known about their influence on soil biogeochemistry. My dissertation research includes a cross-continental field study in Australia, Florida, and greenhouse and growth chamber experiments, focused on the soil-plant interactions of one of the most problematic weeds introduced in south Florida, Lygodium microphyllum (Old World climbing fern). Analysis of field samples from the ferns introduced and their native range indicate that L microphyllum is highly dependent on arbuscular mycorrhizal fungi (AMF) for phosphorus uptake and biomass accumulation. Relationship with AMF is stronger in relatively dry conditions, which are commonly found in some Florida sites, compared to more common wet sites where the fern is found in its native Australia. In the field, L. microphyllum is found to thrive in a wide range of soil pH, texture, and nutrient conditions, with strongly acidic soils in Australia and slightly acidic soils in Florida. Soils with pH 5.5 - 6.5 provide the most optimal growth conditions for L. microphyllum, and the growth declines significantly at soil pH 8.0, indicating that further reduction could happen in more alkaline soils. Comparison of invaded and uninvaded soil characteristics demonstrates that L. microphyllum can change the belowground soil environment, with more conspicuous impact on nutrient-poor sandy soils, to its own benefit by enhancing the soil nutrient status. Additionally, the nitrogen concentration in the leaves, which has a significant influence in the relative growth rate and photosynthesis, was significantly higher in Florida plants compared to Australian plants. Given that L. microphyllum allocates up to 40% of the total biomass to rhizomes, which aid in rapid regeneration after burning, cutting or chemical spray, hence management techniques targeting the rhizomes look promising. Over all, my results reveal for the first time that soil pH, texture, and AMF are major factors facilitating the invasive success of L. mcirophyllum. Finally, herbicide treatments targeting rhizomes will most likely become the widely used technique to control invasiveness of L. microphyllum in the future. However, a complete understanding of the soil ecosystem is necessary before adding any chemicals to the soil to achieve a successful long-term invasive species management strategy.

Nitrogen use efficiency and optimization of nitrogen fertilizer application for stable yields and high quality of cereals grown in conservation agriculture

In most agroecosystems, nitrogen (N) is the most important nutrient limiting plant growth. One management strategy that affects N cycling and N use efficiency (NUE) is conservation agriculture (CA), an agricultural system based on a combination of minimum tillage, crop residue retention and crop rotation. Available results on the optimization of NUE in CA are inconsistent and studies that cover all three components of CA are scarce. Presently, CA is promoted in the Yaqui Valley in Northern Mexico, the country´s major wheat-producing area in which from 1968 to 1995, fertilizer application rates for the cultivation of irrigated durum wheat (Triticum durum L.) at 6 t ha-1 increased from 80 to 250 kg ha-1, demonstrating the high intensification potential in this region. Given major knowledge gaps on N availability in CA this thesis summarizes the current knowledge of N management in CA and provides insights in the effects of tillage practice, residue management and crop rotation on wheat grain quality and N cycling. Major aims of the study were to identify N fertilizer application strategies that improve N use efficiency and reduce N immobilization in CA with the ultimate goal to stabilize cereal yields, maintain grain quality, minimize N losses into the environment and reduce farmers’ input costs. Soil physical and chemical properties in CA were measured and compared with those in conventional systems and permanent beds with residue burning focusing on their relationship to plant N uptake and N cycling in the soil and how they are affected by tillage and N fertilizer timing, method and doses. For N fertilizer management, we analyzed how placement, time and amount of N fertilizer influenced yield and quality parameters of durum and bread wheat in CA systems. Overall, grain quality parameters, in particular grain protein concentration decreased with zero-tillage and increasing amount of residues left on the field compared with conventional systems. The second part of the dissertation provides an overview of applied methodologies to measure NUE and its components. We evaluated the methodology of ion exchange resin cartridges under irrigated, intensive agricultural cropping systems on Vertisols to measure nitrate leaching losses which through drainage channels ultimately end up in the Sea of Cortez where they lead to algae blooming. A throughout analysis of N inputs and outputs was conducted to calculate N balances in three different tillage-straw systems. As fertilizer inputs are high, N balances were positive in all treatments indicating the risk of N leaching or volatilization during or in subsequent cropping seasons and during heavy rain fall in summer. Contrary to common belief, we did not find negative effects of residue burning on soil nutrient status, yield or N uptake. A labeled fertilizer experiment with urea 15N was implemented in micro-plots to measure N fertilizer recovery and the effects of residual fertilizer N in the soil from summer maize on the following winter crop wheat. Obtained N fertilizer recovery rates for maize grain were with an average of 11% very low for all treatments.

Estructuración de los procesos y la función de recursos humanos alineados con el direccionamiento estratégico en Kathmandu restaurante

El direccionamiento estratégico está destinado para que las organizaciones cumplan con sus metas y tengan perdurabilidad en el tiempo; es una forma metodológica en la cual se establecen La formulación y el planteamiento estratégicos, se identifican las brechas entre el sueño de la empresa y su realidad, para desplegar la plata forma estratégica. Kathmandu es un restaurante conocido por su diversidad cultural gastronómica, ubicado en Usaquén al Norte de Bogotá. Su serviespacio reúne los sabores, aromas, decoración y elixires del oriente, su música incluye una fusión de sonidos que permite materializar la experiencia que quiere brindar para satisfacer las expectativas de sus comensales y brindarles una experiencia diferente. Los fines de semana presentan shows de danza de vientre, para acompañar la comida y el rato que dispongan disfrutar en este lugar. Este restaurante tiene un diferenciador en su servicio, que le ofrece una ventaja competitiva, Kathmandu brinda la posibilidad de que además del deleite de sus platos, los clientes puedan adquirir toda la decoración de este lugar, estas son artesanías originales traídas de Nepal, India, Tailandia, Indonesia y sus alrededores. Otro atrayente de este restaurante son los cocteles alusivos a las regiones del oriente, y la narguile que ofrece a sus clientes. Al pasar de los años, ciertos inconvenientes presentados en el negocio, con los clientes, el personal y las utilidades, han hecho que los gerentes se preocupen por encontrar la raíz del problema y buscar la solución óptima para perdurar en el tiempo con los mejores beneficios posibles, pues las estrategias que estaban implementando no van acorde a su misión y visión, por lo que es necesario realizar una restructuración de ciertos procesos enfocados al direccionamiento estratégico. Se realizó un análisis en una reunión junto a las directivas sobre cada área de la organización donde se evidenciaron problemas que deben ser tratados para hacer de Kathmandu una empresa más eficiente, eficaz y productiva. Y prepararla para afrontar los cambios que el tiempo le presente, en cuanto a preferencias de los clientes, competencia, entre otras, bien sean a corto, mediano o largo plazo. Algunos de los principales problemas encontrados son: el servicio al cliente, la selección adecuada de personal y capacitación de este, la falta de manejo de un conducto jerárquico y repartición de funciones entre los colaboradores, el informe adecuado sobre la inconformidad de los clientes con su solución, el manual de funciones, el manejo de inventarios y su rotación, verificación de calidad de los productos, manejo de proveedores, entre otros. Kathmandu, a pesar de tener problemas evidentes, es una empresa que por los servicios y productos que ofrece sigue generando buenas utilidades, por esto los gerentes no le habían prestado la debida atención a estos inconvenientes que están poniendo en juego la perdurabilidad de la empresa y que afecta la optimización de las utilidades y minimización de costes sin afectar la calidad brindada al cliente. El objetivo de este restaurante es que el área de recursos humanos sea restructurada en cada uno de los procesos para articularla al direccionamiento estratégico de Kathmandu; pues en esta área se generan la mayoría de los problemas presentados anteriormente. El presente proyecto pretende diseñar el direccionamiento estratégico del área recursos humanos del restaurante Kathmandu para superar la problemática identificada y garantizar la efectividad de sus procesos y adicionalmente evidenciar la creencia de éxito sostenido que se manejaba en este lugar. Este proyecto se realizara con una metodología mixta, para tener aspectos de la investigación cuantitativa y cualitativa y poder realizar una investigación más completa que lleve a una óptima solución del problema abarcado. Se utilizara el direccionamiento estratégico como herramienta para replantear el área de recursos humanos de la organización y alcanzar la efectividad en sus procesos.

Valor diagnóstico del pepsinógeno i/ii como biomarcador de lesiones pre-malignas y malignas gástricas: revisión sistemática

Antecedentes: El cáncer gástrico se diagnostica tardíamente. Sólo en países como Corea y Japón existen políticas de tamizaje, que se justificarían en cualquier país con alta prevalencia de cáncer gástrico como Colombia o Chile. El análisis del pepsinógeno sérico se ha propuesto para el diagnóstico de lesiones premalignas y malignas gástricas, por lo cual se pretende revisar sistemáticamente en la literatura el valor diagnóstico del cociente pepsinógeno I/II como marcador de lesiones premalignas y malignas gástricas. Metodología: Se revisó la literatura hasta septiembre del 2016 con palabras claves lesiones malignas, premalignas gástricas y pepsinógeno en las bases de datos PubMed, OVID, EMBASE, EBSCO, LILACS, OPENGRAY y Dialnet, artículos de prueba diagnóstica que evaluaran el cociente pepsinógeno I/II en relación con los hallazgos histológicos. Resultados: Se incluyeron 21 artículos conun total de 20601 pacientes, que demuestranuna sensibilidad entre13.7% - 91.2%, una especificidad entre 38.5% - 100%, un Valor Predictivo Positivo entre 6.3% - 100% y un Valor Predictivo Negativo entre 33.3% - 98.8%del cociente pepsinógeno I/II en relación con el diagnósticode lesiones premalignas y malignas gástricas. Conclusiones: Los valores del cociente pepsinógeno I/II disminuidos se relacionan con la presencia delesiones premalignas y malignas gástricas.Dado que tiene mejor especificidad que sensibilidad, en cuanto prueba para tamizaje, sería útil para la selección de pacientes que se beneficiaríande la EVDA. Se requieren más estudios de prueba diagnóstica para validar un punto de corte específico que pueda ser utilizado como valor estándar.
