A influência dos líderes no processo de mudança organizacional: um estudo de caso

Esta dissertação tem por objectivo avaliar a eficácia do processo de mudança organizacional, através das acções dos líderes, da empresa que lidera o mercado de telecomunicações em Cabo Verde, que foi objecto de um processo de reestruturação, que consistiu essencialmente na implementação de um Sistema de Gestão da Qualidade (SGQ). A implementação do referido sistema é entendida, nesta dissertação, como um modelo de mudança organizacional. Para atingir os objectivos preconizados, foi realizado um estudo de caso que contempla uma análise qualitativa dos documentos da empresa e de dados recolhidos através de entrevistas realizadas no período compreendido entre Fevereiro e Agosto de 2010. O estudo procurou compreender o contributo das práticas de liderança para a eficácia da gestão da qualidade. Nesta perspectiva, importa salientar que o tipo de liderança identificado neste estudo de caso é a liderança transformacional, que tecnicamente é o adequado quando se pretende implementar mudanças profundas e que implicam uma redefinição da missão, visão e valores da organização. Importa referir ainda que vários estudos empíricos têm demonstrado de forma consistente, uma relação positiva entre a liderança transformacional e os indicadores de eficiência no trabalho. Procurou-se entender ainda se os líderes na condução do processo de mudança organizacional da empresa estudada, seguiram o modelo proposto por John P. Kotter para a implementação eficaz de mudanças nas organizações, comparando os oito passos propostos pelo autor com os ocorridos na empresa. A avaliação deste estudo de caso permitiu concluir que a essência do modelo foi aplicado. This paper intended to assess the effectiveness of the process of organizational change, through the actions of the leaders of the company that leads the telecommunications market in Cape Verde, which was involved in a restructuration process, covering mainly the implementation of a Quality Management System (QMS). The implementation of this system is understood in this case, as a model of organizational change. To achieve the proposed goals, we performed a case study based on a qualitative analysis of corporate documents and data collected through interviews conducted between February 2010 and August 2010. This study tried to understand the role of leadership practices for the effectiveness of the quality management. In this perspective, it should be noted that the type of leadership identified in this case study is the transformational one, which, technically, is the appropriate when trying to implement significant change, which imply a redefinition of the mission, vision and values of the organization. It should be noted also that several empirical studies have consistently demonstrated a positive relationship between transformational leadership and the performance indicators in the workplace. We also tried to understand if the leaders, in driving the process of organizational change in the company studied, followed the model proposed by John P. Kotter for implementing effective change in organizations, by comparing the eight steps proposed by the author with those verified in the company. The assessment of this case study allowed us to conclude that the essence of the model is applicable to this case.

A implementação do SGQ e a certificação de uma empresa são tidas como robustos alicerces para a continuidade saudável da empresa, tendo em conta o meio envolvente cada vez mais exigente, competitivo, globalizado e globalizante. This investigative work intends to explore the “Quality Management System” and enhances the procedures and techniques that rule its implementation on Organizations, using as model in the present study, ALUCAR, S.A., a rent-a-car company. Our decision to implement this system is due to the fact that it is widely accepted that such realization brings advantages not only to clients, but also to the Organization and to society as a whole. Throughout this work, we will describe the processes of development of the quest for quality in companies, its definitions, dimensions, costs and main mentors, in the branch of the Total Quality Management; we approach aspects of such organizations as ISO and EFQM, and later depict the quality implement situation in Cape Verde. Posterior to that, we characterize the company ALUCAR, S.A., and indicate the preliminary works that ought to be taken into account when implementing quality management, present phases of such accomplishment, a proposal for a Quality Manual and, lastly, the limitations of this study, and the conclusions we have derived from such analysis. While developing the themes related to quality, we provide answers to our research questions, and indicate our general and specific objectives. It is our firm conviction that if the system here appraised is implemented in the mentioned company, following all recommended steps and with a strong involvement of management responsibles, all through the process, surely the objectives praised will be achieved. The implementation of the SGQ system and the certification of a company are two very important steps for a healthy development, knowing that the business milieu is becoming ever more demanding, competitive, globalized and globalizing.

Cost system design and cost management in the Spanish public sector

Cost systems have been shown to have developed considerably in recent years andactivity-based costing (ABC) has been shown to be a contribution to cost management,particularly in service businesses. The public sector is composed to a very great extentof service functions, yet considerably less has been reported of the use of ABC tosupport cost management in this sector.In Spain, cost systems are essential for city councils as they are obliged to calculate thecost of the services subject to taxation (eg. waste collection, etc). City councils musthave a cost system in place to calculate the cost of services, as they are legally requirednot to profit , from these services.This paper examines the development of systems to support cost management in theSpanish Public Sector. Through semi-structured interviews with 28 subjects within oneCity Council it contains a case study of cost management. The paper contains extractsfrom interviews and a number of factors are identified which contribute to thesuccessful development of the cost management system.Following the case study a number of other City Councils were identified where activity-based techniques had either failed or stalled. Based on the factors identified inthe single case study a further enquiry is reported. The paper includes a summary usingstatistical analysis which draws attention to change management, funding and politicalincentives as factors which had an influence on system success or failure.

A Implementação de um Sistema de Gestão da Qualidade: O Caso da C.M. Aveiro

Este relatório tem como objetivo compreender o nível de implementação de um Sistema de Gestão da Qualidade no município de Aveiro. O nosso trabalho empírico e os dados investigados permitiu-nos investigar se houve uma implementação fragmentada ou completa do Sistema de Gestão da Qualidade no município. A fim de entender esse processo foi necessário resumir o contexto histórico da adoção de medidas de qualidade no setor público Português, através de um breve levantamento das fases dessas reformas e dos seus processos de modernização, incluindo as iniciativas e a implementação dos princípios de gestão da qualidade total nos serviços públicos. Neste sentido, este estudo tem como objetivo compreender o impacto e a sustentabilidade da implementação de um Sistema de Gestão da Qualidade na Câmara Municipal de Aveiro. Estamos particularmente preocupados com os desafios e motivações associadas a este processo, de modo a inferir sobre os benefícios que o processo de certificação da qualidade trouxe ao município. Levando em consideração o cenário económico atual, tentou-se também investigar o possível efeito que a crise económica sobre o futuro deste processo de modernização no município. A partir dos dados coletados é possível concluir que houve uma implementação fragmentada do Sistema de Gestão da Qualidade no município de Aveiro. Embora exista a noção da importância da plena implementação Sistema no município, os custos associados a este processo e a situação económica do país e da autarquia representam as principais barreiras no sucesso da implementação plena do Sistema de Gestão da Qualidade no município.

Managing by values in the next milenium: Cultural redesign for strategic organizational change

The system of beliefs and values, that shaped the model for management and organizations during the 20th century, is just not good enough today. In order to keep a business functioning well and competing successfully in markets that are increasingly more global, complex, professionally demanding, constantly changing and oriented towards quality and customer satisfaction a new model is needed. In this paper, we will propose that both Management by Instructions (MBI) and Management by Objectives (MBO) today give notoriously inadequate results. By contrast, description of a new approach labeled: Management by Values (MBV), seem to be emerging as a strategic leadership tool. The paper outlines this approach and discusses the implementation of MBV as a tool to redesign culture in organizations and prepare them for the next millenium.

State of Iowa Department of Administrative Services Human Resource Enterprise: Review of State Hiring Practices, April 30, 2007

The State of Iowa and the Hiring Practices Working Group commissioned this review of the State’s hiring practices in response to recent concerns about these practices involving racial discrimination claims against the Departments of Human Services, Transportation, and Iowa Workforce Development. The State of Iowa should be commended for undertaking this review. The State has a longstanding Affirmative Action Program and commitment to diversity – they instituted their Affirmative Action Program in 1973, and continue their commitment to its success by making the changes necessary to ensure the program is viable and sustainable. Iowa Department of Administrative Services In July 2003, the State created the Iowa Department of Administrative Services (DAS) as a way to manage and coordinate the major resources of state government. DAS provides human resource services through an entrepreneurial management model. Entrepreneurial management is a customer-focused approach to delivering services. The customer departments have input about what services and products they want from DAS and in turn DAS is funded by the customer departments through purchases of DAS services and products. DAS looks to offer new and additional services (for example recruitment support and coordination) to various customers on a fee-for-service basis. A customer council is charged with approving the DAS business plan, establishing the rate for services, and reviewing service delivery and complaints. Under this entrepreneurial model, human resource services are provided by DAS-HRE (Human Resources Enterprise) central staff, 12 DAS-HRE Personnel Officers located at the customer departments, and customer agency staff. The majority of the recruitment and hiring functions are done by the customer (hiring) departments and their staff. Applications for employment are submitted using the BrassRing system with applicants being qualified by DAS-HRE employees. Since the creation of Human Resources Enterprise, DAS-HRE has strived to provide human resource tools to the departments. The Screening Manual and the Supervisor’s Manual are just two examples of the resources created for the hiring departments. They also provide Supervisor Training for newly appointed supervisors. Larger departments have dedicated staff assigned to human resource activities. The staff at the departmental level may or may not have a human resources background. Iowa Population and Workforce The 2000 U.S. Census indicated that Iowa’s population was 2,926,324. According to this census, 92.6 percent of Iowa’s population identified their race as white (alone). The nonwhite alone or minority population (including Black or African American, Asian, Native Hawaiian or Pacific Islander, Hispanic or Latino, American Indian or Alaska Native, two or more races, or some other race) was 7.4 percent.

Gestió d'un portal web d'intercanvi de coneixement

En aquest món on ens ha tocat viure i patir canvis tan durs amb la crisi econòmica que patim, que ens ha fet passar de lligar els gossos amb llonganisses a vigilar en les despeses del dia a dia per poder arribar just a final de mes, és el moment de reinventar-se. És per aquest motiu que presento aquesta idea, on el seu objectiu és desenvolupar una pàgina web que esdevingui un punt de trobada entre usuaris que volen transmetre o ampliar el seu coneixement i oferir-los la possibilitat que entre ells puguin compartir les seves habilitats i destreses. El web consistirà en un panell d’activitats on els usuaris un cop s’hagin registrat puguin crear les activitats que vulguin aprendre o bé ensenyar, tot demanant, si ho desitgen, quelcom a canvi. Aleshores la resta d’usuaris si els interessa l’activitat, poden acceptar la demanda o bé fer una proposta pròpia. A partir d’aquí els usuaris s’han de posar d’acord a l’hora de dur a terme l’activitat. El web disposarà d’una part pels usuaris amb permisos d’administrador perquè puguin gestionar el portal. Aquest projecte s’ha desenvolupat amb el framework de PHP Codeigniter, el qual utilitza la programació per capes MVC, la qual separa la programació en tres parts: el Model, la Vista i el Controlador. També s’han utilitzat els llenguatges HTML5 i CSS3, i jQuery, que és una llibreria de JavaScript. Com a sistema gestor de base de dades s’ha utilitzat el MySQL.

A numerical model for the gamma-ray emission of the microquasar LS 5039

The possible association between the microquasar LS 5039 and the EGRET source 3EG J1824-1514 suggests that microquasars could also be sources of high energy gamma-rays. In this paper, we explore, with a detailed numerical model, if this system can produce the emission detected by EGRET (>100 MeV) through inverse Compton (IC) scattering. Our numerical approach considers a population of relativistic electrons entrained in a cylindrical inhomogeneous jet, interacting with both the radiation and the magnetic fields, taking into account the Thomson and Klein-Nishina regimes of interaction. The computed spectrum reproduces the observed spectral characteristics at very high energy.

The wound watch: an objective staging system for wounds in the diabetic (db/db) mouse model.

As in cancer biology, in wound healing there is a need for objective staging systems to decide for the best treatment and predictors of outcome. We developed in the diabetic (db/db) wound healing model, a staging system, the "wound watch," based on the quantification of angiogenesis and cell proliferation in open wounds. In chronic wounds, there is often a lack of cellular proliferation and angiogenesis that leads to impaired healing. The wound watch addresses this by quantifying the proliferative phase of wound healing in two dimensions (cellular division and angiogenesis). The results are plotted in a two-dimensional graph to monitor the course of healing and compare the response to different treatments.

Long-term C-CO2 emissions and carbon crop residue mineralization in an oxisol under different tillage and crop rotation systems

Soil C-CO2 emissions are sensitive indicators of management system impacts on soil organic matter (SOM). The main soil C-CO2 sources at the soil-plant interface are the decomposition of crop residues, SOM turnover, and respiration of roots and soil biota. The objectives of this study were to evaluate the impacts of tillage and cropping systems on long-term soil C-CO2 emissions and their relationship with carbon (C) mineralization of crop residues. A long-term experiment was conducted in a Red Oxisol in Cruz Alta, RS, Brazil, with subtropical climate Cfa (Köppen classification), mean annual precipitation of 1,774 mm and mean annual temperature of 19.2 ºC. Treatments consisted of two tillage systems: (a) conventional tillage (CT) and (b) no tillage (NT) in combination with three cropping systems: (a) R0- monoculture system (soybean/wheat), (b) R1- winter crop rotation (soybean/wheat/soybean/black oat), and (c) R2- intensive crop rotation (soybean/ black oat/soybean/black oat + common vetch/maize/oilseed radish/wheat). The soil C-CO2 efflux was measured every 14 days for two years (48 measurements), by trapping the CO2 in an alkaline solution. The soil gravimetric moisture in the 0-0.05 m layer was determined concomitantly with the C-CO2 efflux measurements. The crop residue C mineralization was evaluated with the mesh-bag method, with sampling 14, 28, 56, 84, 112, and 140 days after the beginning of the evaluation period for C measurements. Four C conservation indexes were used to assess the relation between C-CO2 efflux and soil C stock and its compartments. The crop residue C mineralization fit an exponential model in time. For black oat, wheat and maize residues, C mineralization was higher in CT than NT, while for soybean it was similar. Soil moisture was higher in NT than CT, mainly in the second year of evaluation. There was no difference in tillage systems for annual average C-CO2 emissions, but in some individual evaluations, differences between tillage systems were noticed for C-CO2 evolution. Soil C-CO2 effluxes followed a bi-modal pattern, with peaks in October/November and February/March. The highest emission was recorded in the summer and the lowest in the winter. The C-CO2 effluxes were weakly correlated to air temperature and not correlated to soil moisture. Based on the soil C conservation indexes investigated, NT associated to intensive crop rotation was more C conserving than CT with monoculture.

Effect of management systems and cover crops on organic matter dynamics of soil under vegetables

Vegetable production in conservation tillage has increased in Brazil, with positive effects on the soil quality. Since management systems alter the quantity and quality of organic matter, this study evaluated the influence of different management systems and cover crops on the organic matter dynamics of a dystrophic Red Latosol under vegetables. The treatments consisted of the combination of three soil tillage systems: no-tillage (NT), reduced tillage (RT) and conventional tillage (CT) and of two cover crops: maize monoculture and maize-mucuna intercrop. Vegetables were grown in the winter and the cover crops in the summer for straw production. The experiment was arranged in a randomized block design with four replications. Soil samples were collected between the crop rows in three layers (0.0-0.05, 0.05-0.10, and 0.10-0.30 m) twice: in October, before planting cover crops for straw, and in July, during vegetable cultivation. The total organic carbon (TOC), microbial biomass carbon (MBC), oxidizable fractions, and the carbon fractions fulvic acid (C FA), humic acid (C HA) and humin (C HUM) were determined. The main changes in these properties occurred in the upper layers (0.0-0.05 and 0.05-0.10 m) where, in general, TOC levels were highest in NT with maize straw. The MBC levels were lowest in CT systems, indicating sensitivity to soil disturbance. Under mucuna, the levels of C HA were lower in RT than NT systems, while the C FA levels were lower in RT than CT. For vegetable production, the C HUM values were lowest in the 0.05-0.10 m layer under CT. With regard to the oxidizable fractions, the tillage systems differed only in the most labile C fractions, with higher levels in NT than CT in the 0.0-0.05 m layer in both summer and winter, with no differences between these systems in the other layers. The cabbage yield was not influenced by the soil management system, but benefited from the mulch production of the preceding maize-mucuna intercrop as cover plant.

Structural changes and degradation of Red Latosols under different management systems for 20 years

Soils are the foundation of terrestrial ecosystems and their role in food production is fundamental, although physical degradation has been observed in recent years, caused by different cultural practices that modify structures and consequently the functioning of soils. The objective of this study was to evaluate possible structural changes and degradation in an Oxisol under different managements for 20 years: no-tillage cultivation with and without crop rotation, perennial crop and conventional tillage, plus a forested area (reference). Initially, the crop profile was described and subsequently, 10 samples per management system and forest soil were collected to quantify soil organic matter, flocculation degree, bulk density, and macroporosity. The results indicated structural changes down to a soil depth of 50 cm, with predominance of structural units ∆μ (intermediate compaction level) under perennial crop and no-tillage crop rotation, and of structural units ∆ (compacted) under conventional tillage and no-tillage. The soil was increasingly degraded in the increasing order: forest => no-tillage crop rotation => perennial crop => no-tillage without crop rotation => conventional tillage. In all managements, the values of organic matter and macroporosity were always below and bulk density always above those of the reference area (forest) and, under no-tillage crop rotation and perennial crop, the flocculation degree was proportionally equal to that of the reference area.

SOIL FUNGISTASIS AGAINST FUSARIUM GRAMINEARUM UNDER DIFFERENT CROP MANAGEMENT SYSTEMS

Soil management, in terms of tillage and cropping systems, strongly influences the biological properties of soil involved in the suppression of plant diseases. Fungistasis mediated by soil microbiota is an important component of disease-suppressive soils. We evaluated the influence of different management systems on fungistasis against Fusarium graminearum, the relationship of fungistasis to the bacterial profile of the soil, and the possible mechanisms involved in this process. Samples were taken from a long-term experiment set up in a Paleudult soil under conventional tillage or no-tillage management and three cropping systems: black oat (Avena strigose L.) + vetch (Vicia sativa L.)/maize (Zea mays L.) + cowpea (Vigna sinensis L.), black oat/maize, and vetch/maize. Soil fungistasis was evaluated in terms of reduction of radial growth of F. graminearum, and bacterial diversity was assessed using ribosomal intergenic spacer analysis (RISA). A total of 120 bacterial isolates were obtained and evaluated for antibiosis, and production of volatile compounds and siderophores. No-tillage soil samples showed the highest level of F. graminearum fungistasis by sharply reducing the development of this pathogen. Of the cropping systems tested, the vetch + black oat/maize + cowpea system showed the highest fungistasis and the oat/maize system showed the lowest. The management system also affected the genetic profile of the bacteria isolated, with the systems from fungistatic soils showing greater similarity. Although there was no clear relationship between soil management and the characteristics of the bacterial isolates, we may conclude that antibiosis and the production of siderophores were the main mechanisms accounting for fungistasis.

WATER INFILTRATION IN TWO CULTIVATED SOILS IN SOUTHERN BRAZIL

Infiltration is the passage of water through the soil surface, influenced by the soil type and cultivation and by the soil roughness, surface cover and water content. Infiltration absorbs most of the rainwater and is therefore crucial for planning mechanical conservation practices to manage runoff. This study determined water infiltration in two soil types under different types of management and cultivation, with simulated rainfall of varying intensity and duration applied at different times, and to adjust the empirical model of Horton to the infiltration data. The study was conducted in southern Brazil, on Dystric Nitisol (Nitossolo Bruno aluminoférrico húmico) and Humic Cambisol (Cambissolo Húmico alumínico léptico) soils to assess the following situations: simulated rains on the Nitisol from 2001 to 2012 in 31 treatments, differing in crop type, sowing direction, type of soil opener on the seeder, amount and type of crop residue and amount of liquid swine manure applied; on the Cambisol, rains were simlated from 2006 to 2012 and 18 treatments were evaluated, differing in crop, seeding direction and crop residue type. The constant of the water infiltration rate into the soil varies significantly with the soil type (30.2 mm h-1 in the Nitisol and 6.6 mm h-1 in the Cambisol), regardless of the management system, application time and rain intensity and duration. At the end of rainfalls, soil-water infiltration varies significantly with the management system, with the timing of application and rain intensity and duration, with values ranging from 13 to 59 mm h-1, in the two studied soils. The characteristics of the sowing operation in terms of relief, crop type and amount and type of crop residue influenced soil water infiltration: in the Nitisol, the values of contour and downhill seeding vary between 27 and 43 mm h-1, respectively, with crop residues of corn, wheat and soybean while in the Cambisol, the variation is between 2 and 36 mm h-1, respectively, in soybean and corn crops. The Horton model fits the values of water infiltration rate into the soil, resulting in the equation i = 30.2 + (68.2 - 30.2) e-0.0371t (R2 = 0.94**) for the Nitisol and i = 6.6 + (64.5 - 6.6) e-0.0537t (R2 = 0.99**) for the Cambisol.
