Airborne pollen of Brisbane, Australia: a five-year record, 1994-1999

The seasonal incidence of pollen in the atmosphere of Brisbane has been established from a near continuous. volumetric trapping program over the five-year period, July 1994-June 1999. Grass pollen accounts for 71.6% of the average annual pollen load with highest densities (up to 150 grains/m(3)) recorded in summer and autumn. Significant contributions were also made by taxa of the Cupressaceae (8.7%) and Urticaceae (1.8%) during spring and of the Pinaceae (4.5%) during winter. Pollen seasons of the Casuarinaceae (6.5%) and Myrtaceae (3.2%) are more extended, the former peaking in late winter and the latter in late spring. The onset and duration of the Poaceae and Urticaceae seasons varied from year to year, being later when precipitation levels were low in the late spring-early summer months. Total pollen numbers and grass pollen densities are substantially less than those recorded from southern Australia. Nevertheless, respiratory disease in Brisbane affects up to 10% of the population, and airborne pollen of Poaceae, Urticaceae, Cupressaceae, Pinaceae, and Myrtaceae have been implicated in the release of allergens.

Analysis of the mouse transcriptome based on functional annotation of 60,770 full-length cDNAs

Only a small proportion of the mouse genome is transcribed into mature messenger RNA transcripts. There is an international collaborative effort to identify all full-length mRNA transcripts from the mouse, and to ensure that each is represented in a physical collection of clones. Here we report the manual annotation of 60,770 full-length mouse complementary DNA sequences. These are clustered into 33,409 'transcriptional units', contributing 90.1% of a newly established mouse transcriptome database. Of these transcriptional units, 4,258 are new protein-coding and 11,665 are new non-coding messages, indicating that non-coding RNA is a major component of the transcriptome. 41% of all transcriptional units showed evidence of alternative splicing. In protein-coding transcripts, 79% of splice variations altered the protein product. Whole-transcriptome analyses resulted in the identification of 2,431 sense-antisense pairs. The present work, completely supported by physical clones, provides the most comprehensive survey of a mammalian transcriptome so far, and is a valuable resource for functional genomics.

The embryonic development of the bodywall and nervous system of the cestode flatworm Hymenolepis diminuta

Cestodes (tapeworms) are a derived, parasitic clade of the phylum Platyhelminthes (flatworms). The cestode body wall represents an adaptation to its endoparasitic lifestyle. The epidermis forms a nonciliated syncytium, and both muscular and nervous system are reduced. Morphological differences between cestodes and free-living flatworms become apparent already during early embryogenesis. Cestodes have a complex life cycle that begins with an infectious larva, called the oncosphere. In regard to cell number, cestode oncospheres are among the simplest multicellular organisms, containing in the order of 50-100 cells. As part of our continuing effort to analyze embryonic development in flatworms, we describe here the staining pattern obtained with acTub in embryos and larvae of the cestode Hymenolepis diminuta and, briefly, the monogenean Neoheterocotyle rhinobatidis. In addition, we labeled the embryonic musculature of Hymenolepis with phalloidin. In Hymenolepis embryos, two different cell types that we interpret as neurons and epidermal gland cells express acTub. There exist only two neurons that develop close to the midline at the anterior pole of the embryo. The axons of these two neurons project posteriorly into the center of the oncosphere, where they innervate the complex of muscles that is attached to the booklets. In addition to neurons, acTub labels a small and invariant set of epidermal gland cells that develop at superficial positions, anteriorly adjacent to the neurons, in the dorsal midline, and around the posteriorly located hooklets. During late stages of embryogenesis they spread and form a complete covering of the embryo. We discuss these data in the broader context of platyhelminth embryology.

Application of fairness theory to service failures and service recovery

This article presents a fairness theory-based conceptual framework for studying and managing consumers’ emotions during service recovery attempts. The conceptual framework highlights the central role played by counterfactual thinking and accountability. Findings from five focus groups are also presented to lend further support to the conceptual framework. Essentially, the article argues that a service failure event triggers an emotional response in the consumer, and from here the consumer commences an assessment of the situation, considering procedural justice, interactional justice, and distributive justice elements, while engaging in counterfactual thinking and apportioning accountability. More specifically, the customer assesses whether the service provider could and should have done something more to remedy the problem and how the customer would have felt had these actions been taken. The authors argue that during this process situational effort is taken into account when assessing accountability. When service providers do not appear to exhibit an appropriate level of effort, consumers attribute this to the service provider not caring. This in turn leads to the customer feeling more negative emotions, such as anger and frustration. Managerial implications of the study are discussed.

The role of gender in reactions to service failure and recovery

Male and female consumers place different emphasis on elements of the service recovery process. Perceptions were influenced by gender of the service provider and by a match of customer and service provider gender. The study, an experimental design with 712 respondents, found that when service providers, irrespective of gender, display concern and give customers voice and a sizable compensation, both men and women reported more positive attitudes compared with when this was not so. Combinations of high voice with high outcome and high voice with high concern were especially important in positively influencing perceptions of effort, regardless of gender. However, the authors also found that there were significant differences between male and female respondents regarding their perceptions of how service recovery should be handled. Women want their views heard during service recovery attempts and to be allowed to provide input. Men, in contrast, do not view voice as important.

Do commercial fishers aggregate around marine reserves? Evidence from Big Creek Marine Ecological Reserve, central California

Marine reserves have been widely touted as a promising strategy for managing fisheries and protecting marine biodiversity. However, their establishment can involve substantial social conflict and may not produce the anticipated biological and economic benefits. A crucial factor associated with the success of marine reserves for enhancing fisheries and protecting biodiversity is the spatial distribution of fishing activity. Fishers may be attracted to the perimeter of a reserve in expectation of spillover of adult fishes. This concentration of effort can reduce spillover of fish to the surrounding fishery and has major implications for the effectiveness of reserves in achieving ecological and socioeconomic goals. We examined the spatial distribution of fishing activity relative to California's Big Creek Marine Ecological Reserve and found no aggregation near the reserve. We discuss the factors driving the spatial distribution of fishing activity relative to the reserve and the relevance of that distribution to the performance and evaluation of marine reserves.

Warranty and optimal reliability improvement through product development

For products sold with warranty, the warranty servicing cost can be reduced by improving product reliability through a development process. However, this increases the unit manufacturing cost. Optimal development must achieve a trade-off between these two costs. The outcome of the development process is uncertain and needs to be taken into account in the determination of the optimal development effort. The paper develops a model where this uncertainty is taken into account. (C) 2003 Elsevier Ltd. All rights reserved.

Managing strategic challenges in community sector organisations

Like those in other sectors, managers in community-based organisations face an uncertain and challenging future. Research and writing about the community sector (non-government, notjor-profit, or third seclOr) has canvassed a wide range of issues. A selective review of the recent literature reveals the breadth of research interest in the challenges facing community sector managers. While some reflection on the implications for managers of current economic and social policy contexts is crucial for this sector, research effort needs to be focused on understanding how third sector managers construe their current strategic challenges and the strategies they use to address them A small sample ofmanagers working in a regional area in South East Queensland was asked to identify current strategic concerns related to the future viability of their organisations. The key issues raised by managers are compared with the issues raised in the research literature. Results -to date indicate that managers' concerns are reflected in the research literature, but that managers are also concemed about the current trends in social policy towards collaboration, amalgamation, and pannership. Implications of these findings for managers operating in this sector are discussed.

Spinal stiffness changes throughout the respiratory cycle

Posteroanterior stiffness of the lumbar spine is influenced by factors, including trunk muscle activity and intra-abdominal pressure (IAP). Because these factors vary with breathing, this study investigated whether stiffness is modulated in a cyclical manner with respiration. A further aim was to investigate the relationship between stiffness and IAP or abdominal and paraspinal muscle activity. Stiffness was measured from force-displacement responses of a posteroanterior force applied over the spinous process of L-2 and L-4. Recordings were made of IAP and electromyographic activity from L-4/L-2 erector spinae, abdominal muscles, and chest wall. Stiffness was measured with the lung volume held at the extremes of tidal volume and at greater and lesser volumes. Stiffness at L-4 and L-2 increased above base-level values at functional residual capacity (L-2 14.9 N/mm and L-4 15.3 N/mm) with both inspiratory and expiratory efforts. The increase was related to the respiratory effort and was greatest during maximum expiration (L-2 24.9 N/mm and L-4 23.9 N/mm). The results indicate that changes in trunk muscle activity and IAP with respiratory efforts modulate spinal stiffness. In addition, the diaphragm may augment spinal stiffness via attachment of its crural fibers to the lumbar vertebrae.

New fluorescence parameters for monitoring photosynthesis in plants - 1. The effect of illumination on the fluorescence parameters of the JIP-test

Chlorophyll fluorescence measurements have a wide range of applications from basic understanding of photosynthesis functioning to plant environmental stress responses and direct assessments of plant health. The measured signal is the fluorescence intensity (expressed in relative units) and the most meaningful data are derived from the time dependent increase in fluorescence intensity achieved upon application of continuous bright light to a previously dark adapted sample. The fluorescence response changes over time and is termed the Kautsky curve or chlorophyll fluorescence transient. Recently, Strasser and Strasser (1995) formulated a group of fluorescence parameters, called the JIP-test, that quantify the stepwise flow of energy through Photosystem II, using input data from the fluorescence transient. The purpose of this study was to establish relationships between the biochemical reactions occurring in PS II and specific JIP-test parameters. This was approached using isolated systems that facilitated the addition of modifying agents, a PS II electron transport inhibitor, an electron acceptor and an uncoupler, whose effects on PS II activity are well documented in the literature. The alteration to PS II activity caused by each of these compounds could then be monitored through the JIP-test parameters and compared and contrasted with the literature. The known alteration in PS II activity of Chenopodium album atrazine resistant and sensitive biotypes was also used to gauge the effectiveness and sensitivity of the JIP-test. The information gained from the in vitro study was successfully applied to an in situ study. This is the first in a series of four papers. It shows that the trapping parameters of the JIP-test were most affected by illumination and that the reduction in trapping had a run-on effect to inhibit electron transport. When irradiance exposure proceeded to photoinhibition, the electron transport probability parameter was greatly reduced and dissipation significantly increased. These results illustrate the advantage of monitoring a number of fluorescence parameters over the use of just one, which is often the case when the F-V/F-M ratio is used.

Local colours for Indonesian National police

As a result of the local autonomy program that commenced in Indonesia in Jan 2001, there is a concern regarding the applicability of the formalized model of security & the possibility of that being replaced by a local community-based security model. This rather informal security model is then promoted to be the only form of security used between societies & the nation. However, this model does not solve the problem because of widespread corruption, collusion, & nepotism, & the many limitations of the Indonesian National Police (Polri), a police department that has a mediocre & generalized level of service. In relation to autonomy, the effort of empowering the police units from the regional police down will bridge the gap between the people's ability to protect themselves & the limitations of those that are sworn to uphold the law. 17 References.

A comparison of the whole-body and segmental methodologies of bioimpedance analysis

Theory supports the use of a segmental methodology (SM) for bioimpedance analysis (BIA) of body water (BW). However, previous studies have generally failed to show a significant improvement when the SM is used in place of a whole-body methodology. A pilot study was conducted to compare the two methodologies in control and overweight subjects. BW of each subject was measured by D2O dilution and also estimated from BIA measurements. Bland and Altman analysis was used to compare the two values of BW. The SM resulted in a small but not significantly improved limits of agreement of measured and BIA estimated BW (psimilar to0.3). This and the results of previous studies suggest that improvements in prediction of BW obtained from application of the SM may be intrinsically small and may not justify the additional effort in application.

Nem privado nem estatal: em busca de uma nova estrat??gia para a provis??o de servi??os p??blicos

A id??ia que anima este artigo ?? a de juntar argumentos que demonstrem a import??ncia de se reformar as rela????es do Estado com a sociedade para que a reforma do aparelho do Estado tenha sucesso. S??o discutidas as vantagens e desvantagens da provis??o dos servi??os p??blicos sociais por meio de organiza????es p??blicas n??o-estatais, como uma estrat??gia para superar a crise de governan??a do Estado contempor??neo e tamb??m como um caminho para reduzir a precariedade dos servi??os sociais. O esfor??o de supera????o da crise do Estado vem se traduzindo na redefini????o do modo de financiamento e da maneira de organizar a execu????o das pol??ticas p??blicas sociais, de forma a garantir efetividade na resposta ??s demandas sociais e maior efici??ncia na produ????o dos servi??os. A desestatiza????o da provis??o dos servi??os sociais coloca as sociedades democr??ticas diante do desafio de resolver como manter a responsabilidade do Estado frente ao interesse p??blico. Trata-se de responder como transitar do estatal para o p??blico, garantindo que a provis??o de servi??os p??blicos n??o dependa exclusivamente do Estado, sem que este abandone seu papel de financiador e regulador das atividades de interesse geral. O que n??o merece mais d??vidas ?? que a constitui????o de uma esfera p??blica que venha a atuar em simetria com o Estado e o mercado, como uma poss??vel solu????o duradoura e democr??tica para a produ????o de bens e servi??os sociais, atrav??s de organiza????es p??blicas n??o-estatais, passe a ser considerada como uma das principais tarefas te??ricas e pr??ticas que desafiam os atores sociais envolvidos com as quest??es da gest??o p??blica.

Insulamento burocr??tico, accountability e transpar??ncia: dez anos de regula????o da Ag??ncia Nacional de Vigil??ncia Sanit??ria

Este artigo estuda os instrumentos e mecanismos de transpar??ncia e accountability das ag??ncias reguladoras brasileiras. Por meio da caracteriza????o dos processos de controle, participa????o e acesso a informa????es da Ag??ncia Nacional de Vigil??ncia Sanit??ria (Anvisa), analisa-se como as ag??ncias t??m utilizado tais instrumentos e mecanismos para acolher e processar diversos interesses do processo regulat??rio, promover a estabilidade das regras do jogo e refor??ar a sua legitimidade no ambiente pol??tico e social em que elas est??o inseridas. Foram utilizados dados relativos aos diversos instrumentos de transpar??ncia e accountability, bem como ??s inst??ncias e mecanismos de participa????o da sociedade no processo regulat??rio da Anvisa. Conclui-se que a accountability das ag??ncias ?? um contrafluxo ?? tend??ncia de insulamento, ao mesmo tempo em que se pode configurar um esfor??o de reconhecimento pela sociedade da chegada de um novo aparato institucional no Estado brasileiro: as ag??ncias reguladoras.

A reestrutura????o da carreira de especialista em pol??ticas p??blicas e gest??o governamental e seu impacto na reforma administrativa de 1995

As reformas administrativas brasileiras sempre foram uma forma de tentar aprimorar a gest??o p??blica em nosso pa??s, mas ?? verdade tamb??m que in??meras vezes elas foram usadas como plataforma eleitoral ou ret??rica em esbo??os de programas de Governo. Podemos considerar como a primeira dessas reformas a realizada na d??cada de 1930 pelo Governo de Get??lio Vargas que reduziu bastante as pr??ticas patrimonialistas de gerir o Estado. Posteriormente tivemos, sem muito sucesso, a tentativa de reforma implantada atrav??s edi????o do Decreto-Lei 200 de 1967, durante os governos militares. Com a redemocratiza????o, tentou-se uma reforma no Governo Sarney, da qual resultou como pontos positivos a cria????o da Escola Nacional de Administra????o P??blica e a cria????o da Carreira de Especialista em Pol??ticas P??blicas e Gest??o Governamental (EPPGG). No Governo Collor tentou-se fazer nova reforma administrativa, que n??o logrou ??xito. J?? no Governo Fernando Henrique Cardoso, o Ministro Bresser Pereira foi respons??vel, a partir de 1995, por implementar uma nova e grande reforma administrativa no Brasil. Um dos objetivos dessa Reforma era o fortalecimento do N??cleo Estrat??gico do Estado; para realizar essa tarefa, Bresser Pereira optou por fortalecer as carreiras do chamado Ciclo de Gest??o do Estado, nesse processo ela realizou uma grande reestrutura????o da carreira de EPPGG. Essa reestrutura????o trouxe para o N??cleo Estrat??gico do Estado um corpo de servidores bem treinados e sintonizados com as propostas de gest??o previstas na Reforma. Esses profissionais tiveram uma participa????o marcante nas mudan??as ocorridas na gest??o da Administra????o P??blica durante os dois Governos de Fernando Henrique, participando de v??rios projetos e ocupando v??rios Cargos de Dire????o em todos os n??veis na Administra????o P??blica. O trabalho de sucesso desses profissionais continuou nos dois mandatos seguintes do Presidente Lula. Na constru????o dessa pesquisa foram utilizados v??rios estudos, livros, artigos e entrevistas que levaram ?? conclus??o que a reestrutura????o da Carreira de EPPGG foi um instrumento eficaz para que a Reforma Administrativa de 1995 tivesse sucesso no objetivo de fortalecer o N??cleo Estrat??gico do Estado.
