Extrinsic and intrinsic factors in the Balanced Scorecard adoption: an empirical study in Portuguese organizations

In this article we aim to analyze the relationship between a set of organizational extrinsic and intrinsic factors and the adoption of the Balanced Scorecard(BSC) by privately-owned Portuguese organizations (large companies and small and médium enterprises).These factos are related to companies age,the diversity of products and services,the nature of the ownership structure,the internationalization,and the organizational size. As a primary means of data collection was carried out a postal survey through a questionnaire sent to 549 privately-owned Portuguese organizations, with na overall responserate of 28.2%. The results indicate that the degree of diversity of the products/services of the organization,the owner- ship of foreign groups,and theo rganizational size are positively associated with the implementation of the BSC.Thus,we conclude that the BSC increases with the degree of diversity of the products/services of the organization,that the Portuguese organizations that use the BSC are mainly owned by foreign groups; and larger organizations are most likely to use this tool.

O Balanced Scored como ferramenta de gestão estratégica na Clínica Oftalmológica Dr. Miguel Sousa Neves, Lda.

A sociedade está cada vez mais complexa, sendo notória a preocupação por parte das organizações no que respeita à qualidade dos serviços prestados. Tal como nas outras atividades, a atenção às mais variadas alterações internas e externas por parte das organizações que prestam cuidados de saúde deve ser uma constante, garantindo assim uma rápida e eficaz resposta aos novos desafios. Neste contexto, as organizações de saúde vêem-se obrigadas a criar e utilizar modelos de gestão mais direcionados aos seus objetivos concretos de forma a atingir os fins que visionaram sendo o Balanced Scorecard (BSC) um dos instrumentos mais vocacionados para este fim. Esta ferramenta, criada por Kaplan e Norton, visa a tradução da estratégia e missão de uma organização em objetivos e medidas divididas por quatro perspetivas diferentes: financeira, clientes, processos internos e aprendizagem e crescimento. O BSC é um modelo bastante flexível e o seu sucesso é reconhecido perante o mundo académico e empresarial. Neste sentido, foi desenvolvida uma proposta de implementação de um BSC para a Clínica Oftalmológica Dr. Miguel Sousa Neves, Lda.. Desta forma, foi definida e proposta uma ferramenta de gestão estratégica, permitindo também destacar um conjunto de melhorias que a mesma poderá trazer à organização. O método de estudo adotado foi o estudo de caso tendo sido realizada uma clarificação das orientações estratégicas da organização em questão através da definição da sua visão, missão e valores e, de seguida, a definição dos objetivos estratégicos e seleção dos indicadores de desempenho para cada perspetiva, garantindo assim o seu alinhamento. Por fim, foi delineado o mapa estratégico onde se apresentam as principais relações de causa-efeito entre as várias perspetivas do BSC. Verificou-se que a organização em análise tem os principais pilares do BSC – missão, valores e visão - bem definidos, tal como uma cultura aberta e comunicação clara, transparente e fluída. Estes elementos são muito relevantes para o início do processo de aplicação do BSC, uma vez que podem facilitar a compreensão e a aceitação do mesmo por parte das pessoas que trabalham na organização. O mapa estratégico desenhado para a Clínica Oftalmológica Dr. Miguel Sousa Neves, Lda. apresenta-se como uma ferramenta útil para a mesma nomeadamente ao fornecer aos funcionários uma linha clara da visão sobre a forma como as suas funções estão ligadas aos objetivos globais da organização; ao definir prioridades; ao identificar, racionalizar e alinhar as diversas iniciativas; ao ligar a estratégia com a afetação dos recursos disponíveis, orientando-os para o apoio ao cumprimento dos objetivos estratégicos da organização e satisfação das necessidades dos utentes; e ao incentivar a aprendizagem e a melhoria contínua dos colaboradores e da organização como um todo. Face ao exposto, o BSC poderá permitir à Clínica concentrar-se nas suas questões essenciais, estabelecendo as relações de causa-efeito para atingir os seus fins.

Zwitterionic and charge-balanced polyampholyte copolymer hydrogels

Zwitterionic copolymers were synthesised from N,N-dimethyl-N-(2- acryloylethyl)-N-(3-sulfopropyl) ammonium betaine (SPDA) and 2-hydroxyethyl methacrylate (HEMA) produce a series of polyzwitterion hydrogels. For the synthesis of the charge-balanced copolymer hydrogels, two cationic monomers were selected: 2-(diethylamino) ethyl methacrylate (DMAEMA) and 3-(dimethylamino) propyl methacrylamide (DMAPMA), and an anionic monomer; 2-acrylamido-2- methylpropane sulphonic acid (AMPS). Two series of charge-balanced copolymers were synthesized from stoichiometrically equivalent ratios of DMAEMA or DMAPMA and AMPS with HEMA as a termonomer. All synthesized copolymers produced clear and cohesive hydrogels. The zwitterionic and charge-balanced copolymers displayed similar equilibrium water contents together with similar mechanical and surface energy properties. The swelling of the zwitterionic and the charge-balanced copolymers shows some features of antipolyelectrolyte behavior.

Casemix accounting systems and medical coding:organisational actors balanced on "leaky black boxes"

The adoption of DRG coding may be seen as a central feature of the mechanisms of the health reforms in New Zealand. This paper presents a story of the use of DRG coding by describing the experience of one major health provider. The conventional literature portrays casemix accounting and medical coding systems as rational techniques for the collection and provision of information for management and contracting decisions/negotiations. Presents a different perspective on the implications and effects of the adoption of DRG technology, in particular the part played by DRG coding technology as a part of a casemix system is explicated from an actor network theory perspective. Medical coding and the DRG methodology will be argued to represent ``black boxes''. Such technological ``knowledge objects'' provide strong points in the networks which are so important to the processes of change in contemporary organisations.

Carrier lifetime and exciton saturation in a strain-balanced InGaAs/InAsP multiple-quantum-well

The bleaching of the n = 1 heavy-hole and light-hole exciton absorption has been studied at room temperature and zero bias in a strain-balanced InGaAs/InAsP multiple quantum well. Pump-probe spectroscopy was used to measure the decay of the light-hole absorption saturation, giving a hole lifetime of only 280 ps. As only 16 meV separates the light- and heavy-hole bands, the short escape time can be explained by thermalization between these bands followed by thermionic emission over the heavy-hole barrier. The saturation density was estimated to be 1 × 1016 cm-3; this is much lower than expected for tensile-strained wells where both heavy and light holes have large in-plane masses. © 1998 American Institute of Physics.

Does the balanced scorecard make a difference to the strategy development process?

A great number of strategy tools are being taught in strategic management modules. These tools are available to managers for use in facilitating strategic decision-making and enhancing the strategy development process in their organisations. A number of studies have been published examining which are the most popular tools; however there is little empirical evidence on how their utilisation influences the strategy process. This paper is based on a large scale international survey on the strategy development process, and seeks to examine the impact of a particular strategy tool, the Balanced Scorecard, upon the strategy process. The Balanced Scorecard is one of the most popular strategy tools whose use has evolved since its introduction in the 1990’s. Recently, it has been suggested that as a strategy tool, Balanced Scorecard can influence all elements of the strategy process. The results of this study indicate that although there are significant differences in some elements of the strategy process between the organisations that have implemented the Balanced Scorecard and those that have not, the impact is not comprehensive.

Zwitterionic and charge-balanced (polyampholyte) copolymer hydrogels

Zwitterionic compounds, or zwitterions, are electrically neutral compounds having an equal number of formal unit charges of opposite sign. In common polyzwitterions the zwitterionic groups are usually located in pendent groups rather than the backbone of the macromolecule. Polyzwitterions contain both the anion and cation in the same monomeric unit, unlike polyampholytes which can contain the anion and cation in different monomeric units. The use of cationic and anionic monomers (or monomers capable of becoming charged) in stoichiometric equivalent proportions produces charge-balanced polyampholyte copolymers. Hydrogel materials produced from zwitterionic monomers have been proposed for use and are used in many biomaterial applications but synthetic charge-balanced polyampholyte are less common. Certain properties of hydrogels which are important for their successful use as biomaterials, these include the equilibrium water content, mechanical, surface energy, oxygen permeability, swelling and the coefficient of friction. The zwitterionic monomer N,N-dimethyl-N-(2-acryloylethyl)-N-(3-sulfopropyl) ammonium betaine (SPDA) was synthesized with 2-hydroxyethly acrylate (HEMA) as the comonomer to produce a series of polyzwitterion hydrogels. To produce charged-balanced copolymer hydrogels two “cationic” monomers were selected; 2-(diethylamino) ethyl methacrylate (DMAEMA) and 3-(dimethylamino) propyl methacrylamide (DMAPMA) and an anionic monomer; 2-acrylamido 2,2 methylpropane sulphonic acid (AMPS). Two series’ of charge-balanced copolymers were synthesized from stoichiometric equivalent ratios of DMAEMA or DMAPMA and AMPS with HEMA as a terpolymer. The zwitterionic copolymer and both charge-balanced copolymers produced clear, cohesive hydrogels. The zwitterionic and charge-balanced copolymers displayed similar EWC’s along with similar mechanical and surface energy properties. The swelling of the zwitterionic copolymer displayed antipolyelectrolyte behavior whereas the charge-balanced copolymers displayed behaviour somewhere between this and a typical polyelectrolyte. This work describes some aspects of the polymerisation and properties of SPDA copolymers and charge-balanced (polyampholyte) copolymers relevant to their potential as biomedical / bioresponsive materials. The biomimetic nature of SPDA together with its compatibility with other monomers makes it a useful and complimentary addition to the building blocks of biomaterials.

Charge-balanced copolymer hydrogels:potential as biomedical materials

Polyzwitterionic-containing hydrogel materials been proposed for use in biomaterial applications. Polyzwitterions contain anions and cations in the same monomeric unit, unlike polyampholytes which contain them in different monomeric units. The use of cationic and anionic monomers in stoichiometrically equivalent proportions produces charge-balanced polyampholytes (PA) copolymers. Membranes prepared using either betaine-containing (BT) polyzwitterionic copolymers or PA copolymers can share similar properties, but the range of EWCs offered by membranes incorporating BT and PA monomers is greater than that for conventional neutral hydrogels and methacrylic acid-based systems. Here we compare properties of BT-containing and PA-containing copolymer membranes, relevant to their potential as biomedical materials. Membranes of the copolymers were prepared as previously described. Surface energy was determined using a GBX Digidrop (GBX Scientific Instruments), with diidomethane and water as probes. The absorption of proteins was determined by soaking the membranes in 1mg/ml protein solutions for a predetermined time, and measuring UV absorption of the membranes at certain wavelengths. The BT and PA copolymer membranes displayed similar values for the polar components and dispersive components of total surface free energy. This was perhaps not surprising when the structures of the monomers were considered. The BT and PA copolymer membranes displayed differences in their protein absorption over time, with the PA demonstrating higher uptake of protein than the BT. In addition to the aforementioned greater EWC range, the use of BT and PA copolymer membranes also avoids some of the problems associated with net anionicity. Comparison of the BT copolymer with the “pseudo” zwitterionic PA copolymers shows that controlled molecular architecture is required to gain the benefits of balancing the charges present in the copolymers in a way that will make them beneficial to hydrogel design.
