Mobile digital technology: Emerging issues for marketing

The growth of direct marketing has been attributed to rapid advances in technology and the changing market context. The fundamental ability of direct marketers to communicate with consumers and to elicit a response, combined with the ubiquitous nature and power of mobile digital technology, provides a synergy that will increase the potential for the success of direct marketing. The aim of this paper is to provide an analytical framework identifying the developments in the digital environment from e-marketing to m-marketing, and to alert direct marketers to the enhanced capabilities available to them.

Regulatory interactions in Arabidopsis thaliana acetohydroxyacid synthase

Acetohydroxyacid synthase (AHAS; EC 4.1.3.18) contains catalytic and regulatory subunits, the latter being required for sensitivity to feedback regulation by leucine, valine and isoleucine. The regulatory subunit of Arabidopsis thaliana AHAS possesses a sequence repeat and we have suggested preciously that one repeat binds leucine while the second binds valine or isoleucine, with synergy between the two sites. We have mutated four residues in each repeat, based on a model of the regulatory subunit. The data confirm that there are separate leucine and valine/isoleucine sites, and suggest a complex pathway for regulatory signal transmission to the catalytic subunit.

A rapid method for determining recent sunscreen use in field studies

The role of sunscreens in preventing skin cancer and melanoma is the focus of ongoing research. Currently, there is no objective measure which can be used in field studies to determine whether a person has applied sunscreen to their skin, and researchers must use indirect assessments such as questionnaires. We sought to develop a rapid, non-invasive method for identifying sunscreen on the skin for use in epidemiological studies. Our basic method is to swab the skin, elute any residues which have been adsorbed onto the swab by rinsing in ethanol, and submit the eluted washings for spectrophotometric analysis. In a controlled study, we applied 0.1 ml of sunscreen to a 50 cm(2) grid on both forearms of 21 volunteers. Each forearm was allocated one of 10 different sunscreen brands. The skin was swabbed after intervals of 20 min, 1 h, 2 h and 4 h. In a field study conducted among 12 children aged 2-4 years attending a child care centre, sunscreen was applied to the faces of half the children. Swabs were then taken from the face and back of all children without knowledge of sunscreen status. In the controlled study, sunscreen was clearly detectable up to 2 h after application for all brands containing organic sunscreen, and marginally detectable at 4 h. In the field study, this method correctly identified all children with and without sunscreen. We conclude that spectrophotometric analysis of skin swabs can reliably detect the presence of sunscreen on the skin for up to 2 It after application. (C) 2002 Elsevier Science B.V.

Role of China in the quest to define and control severe acute respiratory syndrome

China holds the key to solving many questions crucial to global control of severe acute respiratory syndrome (SARS). The disease appears to have originated in Guangdong Province, and the causative agent, SARS coronavirus, is likely to have originated from an animal host, perhaps sold in public markets. Epidemiologic findings, integral to defining an animal-human linkage, may be confirmed by laboratory studies; once animal host(s) are confirmed, interventions may be needed to prevent further animal-to-human transmission. Community seroprevalence studies may help determine the basis for the decline in disease incidence in Guangdong Province after February 2002. China will also be able to contribute key data about how the causative agent is transmitted and how it is evolving, as well as identifying pivotal factors influencing disease outcome.

Key issues in determining the ethics of research subject payment: the special case of drug abuse epidemiology

The authors identify key issues that researchers, funding bodies, ethics committees and ethicists might consider in contemplating research subject payment ethics. They argue that what is missing from the broader debate is due consideration of ethics committee decision processes; research subject reasons for participation; and current research practices. The authors explore these issues and how they relate to existing guidelines on voluntary consent, and arguments that have been proposed for and against research subject payments.

Managing urinary incontinence across the lifespan

In the 1996 baseline surveys of the Australian Longitudinal Study of Women's Health (ALSWH), 36.1% of mid-age women (45-50) and 35% of older women (70-75) reported leaking urine. This study aimed to investigate (a) the range of self-management strategies used to deal with urinary incontinence (UI); (b) the reasons why many women who report leaking urine do not seek help for UI; and (c) the types of health professionals consulted and treatment provided, and perceptions of satisfaction with these, among a sample of women in each age group who reported leaking urine often' at baseline. Five hundred participants were randomly selected from women in each of the mid-age and older cohorts of the ALSWH who had reported leaking urine often in a previous survey. Details about UI (frequency, severity, and situations), self-management behaviors and help-seeking for UI, types of health professional consulted, recommended treatment for the problem, and satisfaction with the service provided by health care professionals and the outcomes of recommended treatments were sought through a self-report mailed follow-up survey. Most respondents had leaked urine in the last month (94% and 91% of mid-age and older women, respectively), and 72.2% and 73. 1% of mid-aged and older women, respectively, had sought help or advice about their UI. In both age groups, the likelihood of having sought help significantly increased with severity of incontinence. The most common reasons for not seeking help were that the women felt they could manage the problem themselves or they did not consider it to be a problem.. Many women in both cohorts had employed avoidance techniques in an attempt to prevent leaking urine, including reducing their liquid consumption, going to the toilet just in case, and rushing to the toilet the minute they felt the need to. Strategies are needed to inform women who experience UI of more effective management techniques and the possible health risks associated with commonly used avoidance behaviors. There may be a need to better publicize existing incontinence services and improve access to these services for women of all ages.

Urinary incontinence across the lifespan

Aims: The objectives of the current study were (1) to measure type and severity of urinary leakage and (2) to investigate the association between these factors and age-related life events and conditions in three groups of Australian women with a history of urinary leakage. Methods: Five hundred participants were randomly selected from women in the young (aged 18-22 in 1996), mid-age (4550),and older (70-75) cohorts of the Australian Longitudinal Study of Women's Health (ALSWH) who had reported leaking urine in the 1996 baseline survey. Details about leaking urine (frequency, severity, situations) and associated factors (pregnancy, childbirth, body mass index [BMI]) were sought through self-report mailed follow-up surveys in 1999. Results & Conclusions: Response rates were 50, 83, and 80% in the young, mid-age, and older women, respectively. Most women confirmed that they had, leaked urine in the past month, and the majority of these were cases of mixed incontinence. Incontinence severity tended to increase with BMI for women of all ages, and increased severity scores were associated with having urine that burns or stings. Additional independent risk factors for increasing incontinence severity were heavy smoking in young women, past or present use of hormone replacement therapy in older women, and BMI and history of hysterectomy in mid-age women.

Quality of life assessment in the community-dwelling elderly: Validation of the Assessment of Quality of Life (AQoL) Instrument and comparison with the SF-36

Measurement of Health-Related Quality of Life (HRQoL) of the elderly requires instruments with demonstrated sensitivity, reliability, and validity, particularly with the increasing proportion of older people entering the health care system. This article reports the psychometric properties of the 12-item Assessment of Quality of Life (AQoL) instrument in chronically ill community-dwelling elderly people with an 18-month follow-up. Comparator instruments included the SF-36 and the OARS. Construct validity of the AQoL was strong when examined via factor analysis and convergent and divergent validity against other scales. Receiver Operator Characteristic (ROC) curve analyses and relative efficiency estimates indicated the AQoL is sensitive, responsive, and had the strongest predicative validity for nursing home entry. It was also sensitive to economic prediction over the follow-up. Given these robust psychometric properties and the brevity of the scale, AQoL appears to be a suitable instrument for epidemiologic studies where HRQoL and utility data are required from elderly populations.

Combining nonthermal technologies to control foodborne microorganisms

Novel nonthermal processes, such as high hydrostatic pressure (HHP), pulsed electric fields (PEFs), ionizing radiation and ultrasonication, are able to inactivate microorganisms at ambient or sublethal temperatures. Many of these processes require very high treatment intensities, however, to achieve adequate microbial destruction in low-acid foods. Combining nonthermal processes with conventional preservation methods enhances their antimicrobial effect so that lower process intensities can be used. Combining two or more nonthermal processes can also enhance microbial inactivation and allow the use of lower individual treatment intensities. For conventional preservation treatments, optimal microbial control is achieved through the hurdle concept, with synergistic effects resulting from different components of the microbial cell being targeted simultaneously. The mechanisms of inactivation by nonthermal processes are still unclear; thus, the bases of synergistic combinations remain speculative. This paper reviews literature on the antimicrobial efficiencies of nonthermal processes combined with conventional and novel nonthermal technologies. Where possible, the proposed mechanisms of synergy is mentioned. (C) 2003 Elsevier Science B.V. All rights reserved.

'Localizing the national' - The rediscovery and reshaping of local campaigning in Australia

Pippa Norris provides a schematic account of the evolution of campaigning through premodern, modern and postmodern stages. In particular she points to an emerging postmodern phase of electioneering characterized by a renewed emphasis upon direct forms of engagement which resonate with an earlier period in which campaigns were locally fought and largely dependent upon the canvassing efforts of party workers and volunteers. Norris's analysis offers a useful prism with which to view recent developments in electioneering in Australia. In the past several elections the rival Labor and Liberal parties have attempted to achieve a synergy between their centrally conducted and constituency-level campaigns by ensuring that their national campaigns are locally relevant and address local concerns. Their efforts to 'localize the national' meld the use of sophisticated software with elements of a traditional 'meet and greet' politics and suggest that local campaigning may now have a new shape and importance.

Mecanismos de governança corporativa na pequena empresa familiar

Esta dissertação tem como objetivo descrever e analisar como o fenômeno da governança corporativa articula mecanismos de gestão e impacta na dinâmica de uma pequena organização familiar. Para isso, utilizou-se as perspectivas de Fan (2001) e Silva Junior (2006), que tratam da governança corporativa, e de Chandler (1994), para empresas familiares. Através de abordagem qualitativa com ênfase em um estudo de caso, uma triangulação de dados foi realizada, utilizando a entrevista semiestruturada, observação assistemática ou livre e pesquisa de documentos, e a análise dos dados foi realizada por análise de conteúdo. Verificou-se a presença do fenômeno da governança por intermédio da identificação dos fatores de diferenciação, resultando na implantação de mecanismos de governança ao longo do ciclo de vida da organização familiar, o que possibilitou mudanças em seu controle, no seu processo sucessório e na sua profissionalização. Quanto ao controle, foram verificados que os mecanismos de “manutenção do status quo”, “aconselhamento profissional”, “sinergia de interesses”, “regulamentação financeira da sociedade”, “atribuições e responsabilidades”, “alinhamento de interesses do negócio” e “proteção do empreendimento familiar” possibilitaram a modificação e manutenção do controle da empresa com os sócios. Quanto ao eixo da profissionalização, foi verificado que os mecanismos de “regulamentação financeira da sociedade”, “atribuições e responsabilidades”, “alinhamento de interesses do negócio”, “proteção do empreendimento familiar” e “atenção aos interesses dos stakeholders” foram responsáveis por prover as modificações neste quesito e indicar que a empresa caminha no sentido de se profissionalizar. Quanto ao processo sucessório, verificou-se que a terceira geração não tem interesse na empresa, o que podem resultar na contratação de um profissional externo para gerir a mesma, respeitando a questão dos valores familiares e a cultura organizacional ou conduzir à sucessão recursiva. Aparentemente, observou-se que a segunda questão foi mais evidente, visto que a saída do último irmão do negócio culmina com a venda da empresa familiar, gerando duas alternativas: a compra da empresa por um grupo de sócios ou outra empresa não familiar, o que resultaria na “morte” da empresa enquanto empresa familiar; ou a sua compra por outra família ou empresa familiar, preservando sua classificação inicial.

Educação corporativa : uma análise sobre sua contribuição no desenvolvimento de competências no trabalho em uma empresa de mineração

O presente trabalho tem como objetivo descrever um Programa de Desenvolvimento oferecido pela Universidade Corporativa de empresa mineradora, com atuação em Vitória/ES, e compreender as possíveis relações deste Programa com o desenvolvimento das competências profissionais esperadas pela Organização. A Empresa Gama, que assim será identificada durante todo o trabalho, teve o início de sua Universidade Corporativa no ano de 2003, sob o propósito de transformar vidas desenvolvendo pessoas, e é vista pela Empresa Gama como fator importante para a geração de competitividade, para evolução nos negócios e aumento da sinergia organizacional. Dentre todos os Programas ofertados, opta-se pelo estudo do Programa “Trilha de Gestão e Liderança”, lançado em 2004, e voltado para a formação de gestores da Empresa Gama. Para a realização desta pesquisa qualitativa, foram entrevistados quatro Supervisores da Empresa Gama, que tiveram a oportunidade de participar da “Trilha de Gestão e Liderança”. Foram realizadas entrevistas semi-estruturadas e pesquisa documental para obtenção de dados. Opta-se pela Analise de Conteúdo como método de análise. Compreende-se que, para a Empresa Gama, o Programa “Trilha de Gestão e Liderança” é uma importante ferramenta para o desenvolvimento das competências esperadas pela organização. Contudo, não se trata da principal ferramenta, estando nítido que este desenvolvimento vai muito além dos Programas oferecidos por sua Universidade Corporativa.

Estudo epidemiológico da Leishmaniose canina na zona da Arrábida

A Leishmmaniose canina é uma zoonose endémica provocada por um protozoário do género Leishmania cujo ciclo de vida requer a existência de um hospedeiro intermediário, o flebótomo e de um hospedeiro definitivo, o cão. É uma doença sistémica cuja sintomatologia clássica inclui a anorexia, letargia, poliúria e polidipsia, lesões cutâneas, linfadenomegália, epistáxis e onicogrifose. Muitos animais podem estar infectados mas permanecerem assintomáticos. O diagnóstico deve ser feito pela conjugação da sintomatologia clínica, resultados hematológicos e bioquímicos e resultados laboratoriais como testes serológicos e/ou provas de biologia molecular. Existem várias formas de tratamento da doença, no entanto nenhum protocolo leva à cura parasitológica da doença, mas apenas à remissão da sintomatologia. Várias medidas preventivas podem ser levadas a cabo, como o uso de coleiras insecticidas e num futuro próximo a possível vacinação. O estudo epidemiológico apresentado utilizou uma amostra de 60 cães, aos quais foi realizado um exame clínico e recolha de sangue para análise de hemograma, parâmetros bioquímicos e análise laboratorial, com o fim de se diagnosticar Leishmaniose canina na zona da Arrábida. Foram diagnosticados 34 animais infectados, dos quais 13 eram portadores assintomáticos descobertos pelo uso das técnicas de Imunofluorescência Indirecta, Teste de Aglutinação Directa e Polymerase Chain Reaction.

Mortality problems in Brazil and in Germany: past-present-future. Learning from each other?

This article was written by a Swiss-German historical demographer after having visited different Brazilian Universities in 1984 as a guest-professor. It aims at promoting a real dialog between developed and developing countries, commencing the discussion with the question: Can we learn from each other? An affirmative answer is given, but not in the superficial manner in which the discussion partners simply want to give each other some "good advice" or in which the one declares his country's own development to be the solely valid standard. Three points are emphasized: 1. Using infant mortality in S. Paulo from 1908 to 1983 as an example, it is shown that Brazil has at its disposal excellent, highly varied research literature that is unjustifiably unknown to us (in Europe) for the most part. Brazil by no means needs our tutoring lessons as regards the causal relationships; rather, we could learn two things from Brazil about this. For one, it becomes clear that our almost exclusively medical-biological view is inappropriate for passing a judgment on the present-day problems in Brazil and that any conclusions so derived are thus only transferable to a limited extent. For another, we need to reinterpret the history of infant mortality in our own countries up to the past few decades in a much more encompassing "Brazilian" sense. 2. A fruitful dialog can only take place if both partners frankly present their problems. For this reason, the article refers with much emprasis to our present problems in dealing with death and dying - problems arising near the end of the demographic and epidemiologic transitions: the superanuation of the population, chronic-incurable illnesses as the main causes of death, the manifold dependencies of more and more elderly and really old people at the end of a long life. Brazil seems to be catching up to us in this and will be confronted with these problems sooner or later. A far-sighted discussion already at this time seems thus to be useful. 3. The article, however, does not want to conclude with the rather depressing state of affairs of problems alternatingly superseding each other. Despite the caution which definitely has a place when prognoses are being made on the basis of extrapolations from historical findings, the foreseeable development especially of the epidemiologic transition in the direction of a rectangular survival curve does nevertheless provide good reason for being rather optimistic towards the future: first in regards to the development in our own countries, but then - assuming that the present similar tendencies of development are stuck to - also in regard to Brazil.
