Product market deregulation and the U.S. employment miracle

We consider the dynamic relationship between product market entry regulation and equilibrium unemployment. The main theoretical contribution is combining a job matchingmodel with monopolistic competition in the goods market and individual wage bargaining.Product market competition affects unemployment by two channels: the output expansion effect and a countervailing effect due to a hiring externality. Competition is then linked to barriers to entry. We calibrate the model to US data and perform a policy experiment to assess whether the decrease in trend unemployment during the 1980 s and 1990 s could be attributed to product market deregulation. Our quantitative analysis suggests that under individual bargaining, a decrease of less than two tenths of a percentage point of unemployment rates can be attributed to product market deregulation, a surprisingly small amount.

O Sistema de Custeio “Abc” (Activity Based Costing) Como Instrumento Privilegiado de Gestão Empresarial em Cabo Verde

Com a internacionalização da economia e um mercado cada vez mais competitivo e globalizado, os gestores começam a ter a consciência de que é necessário melhorar a eficiência e reestruturar a empresa, voltando-a para eficácia, tornaram-se metas comuns no moderno ambiente de negócios. O conhecimento exacto dos custos, seu perfeito controlo e coerente mensuração passam a ser uma necessidade das empresas para que seus gerentes possam tomar decisões estratégicas e, consequentemente, fazer melhor uso dos recursos organizacionais, cada vez mais limitados. Para atender a esses anseios, as organizações vêm buscando, cada vez mais, utilizar o sistema de custeio ABC (Activity Based Costing) ou custeio baseado em actividades, como sendo, um método de apuramento de custos que tem vindo a ganhar alguma popularidade nos últimos tempos. Este método fornece informação mais correcta e precisa sobre os custos, a qual é extremamente útil para auxiliar os gestores na tomada de decisões. Apesar de ser um conceito universal, a implementação bem sucedida do ABC não é igual em todas as organizações e deve ser adaptada a uma estratégia, estrutura, capacidade e necessidade únicas da empresa. O object ivo deste trabalho é aprofundar o conhecimento sobre este método “ABC”, estudando a sua aplicabilidade nas empresas de Cabo Verde, mas concretamente na cidade da Praia. Pretende-se, também, identificar as dificuldades no decorrer da sua implementação e averiguar se as empresas que adoptam ou estão a adoptar o ABC consideram-no uma ferramenta de gestão empresarial.

Effects of employment protection and product market regulations on the Italian labor market

Labor market regulations have often being blamed for high and persistentunemployment in Europe, but evidence on their impact remains mixed. Morerecently, attention has turned to the impact of product market regulationson employment growth. This paper analyzes how labor and product marketregulations interact to affect turnover and employment. We present a matchingmodel which illustrates how barriers to entry in the product market mitigatethe impact of labor market deregulation. We, then, use the Italian SocialSecurity employer-employee panel to study the interaction between barriersto entry and dismissal costs. We exploit the fact that costs for unjustdismissals in Italy increased for firms below 15 employees relative to biggerfirms after 1990. We find that the increase in dismissal costs after 1990decreased accessions and separations in small relative to big firms,especially for women. Moreover, consistent with our model, we find evidencethat the increase in dismissal costs had smaller effects on turnover for womenin sectors faced with strict product market regulations.

Proposta de Implementação do Time-Driven Activity - Based Costing numa Empresa Industrial

O presente trabalho tem como objectivo a apresentação do processo de concepção e implementação de um projecto-piloto de um sistema de custeio baseado em actividades e tempo – TDABC, numa empresa industrial de conserva de pescado, Frescomar, S.A. Mais especificamente o trabalho desenvolveu-se na apuração do custo da área de produção da empresa objecto de estudo. O sistema de custeio Time-Driven Activity-Based Costing (TDABC) representa um modelo alternativo aos sistemas tradicionais da contabilidade de custos, e é uma evolução do Activity-Based Costing (ABC). O sistema ABC surgiu durante a década de 1980 e tem vindo a evoluir desde então. Muitas empresas abandonaram o ABC, pois este método de custeio, além de não conseguir captar a complexidade das suas operações, a sua implementação é demorado, e é muito dispendioso de aplicar e manter. Com o método TDABC encontra-se uma alternativa para dirimir estes problemas. Observou-se a necessidade do desenvolvimento de apenas algumas equações de tempo (time equations) para representar as principais actividades da área de produção. Foram observadas, durante a realização do estudo, vários dos benefícios do TDABC como: a facilidade em modelar actividades complexas por meio das equações de tempo, obtenção rigorosa de gastos e o baixo tempo de desenvolvimento do modelo. Contudo, também foram identificadas algumas limitações como subjectividade no cálculo do tempo de execução das actividades e dificuldade em se estimar as equações de tempo para actividades pouco estruturadas.

IMPORTÂNCIA E UTILIZAÇÃO DO MÉTODO ABC (ACTIVITY BASED COSTING) COMO SISTEMA DE CUSTEIO – ANALISE DA SITUAÇAO NAS EMPRESAS INDUSTRIAIS DA CIDADE DA PRAIA

O presente trabalho cujo tema é Importância e Utilização de Método ABC (Actvity Based Costing) como Sistema de Custeio, tem como objetivo principal analisar a importância do método ABC no processo de tomada de decisão por parte dos gestores das empresas. Kaplan e Cooper, na década de 80 do século passado, demonstraram que os sistemas de custeio tradicionais são insuficientes para satisfazer as necessidades atuais das empresas, visto que um dos maiores problemas atualmente enfrentados pelas empresas em relação ao custeio dos produtos é a dimensão sempre crescente dos custos indiretos. Por outro lado, os sistemas tradicionais de apuramento de custo não imputam adequadamente os custos indiretos da produção aos produtos, dificultando uma análise de custos. E diante disso, criaram o sistema de custeio baseado na atividade. O ABC parte de um princípio de base muito simples: os recursos são consumidos por atividades e estas são consumidas pelos objetos de custeio. Este sistema de custeio veio dinamizar e dar outra credibilidade à Contabilidade de Gestão, pela importância que dá às atividades e pela visão da organização e do método de gestão, permite em princípio, um mais exato custeio dos produtos e uma mais apurada avaliação de desempenho. Ao identificar atividades que não acrescentam valor, vem facultar informação que permite uma reorganização da estrutura da empresa, e a sua consequente melhoria em termos de rentabilidade e competitividade. O presente estudo resulta do levantamento realizado e das análises das informações e dados das grandes e médias empresas industriais da Cidade da Praia, através dum inquérito por questionário. De acordo com o resultado obtido, concluiu-se que a maioria das grandes e médias empresas industriais da Cidade da Praia não utilizam o método ABC devido ao desconhecimento desta técnica e também verificou-se que o ABC é um importante instrumento de tomada de decisão por parte dos gestores das empresas.

Growth Arrest-Specific Gene 6 product modulates innate immunity in sepsis

Background: Growth Arrest-Specific Gene 6 product (Gas6) is, like anticoagulant protein C, a vitamin K-dependent protein. Our aim was to determine whether Gas6 plays a role in sepsis. Materials and methods: We submitted mice lacking Gas6 (Gas6)/)) or one of its receptors (Axl)/), Tyro3)/) or Mertk)/)) to LPS-induced endotoxemia and peritonitis (cecal ligation and puncture (CLP) and inoculation of E. coli). In addition, we measured Gas6 or its soluble receptors in plasma of eight volunteers that received LPS, 13 healthy subjects, 28 patients with severe sepsis, and 18 patients with non-infectious inflammatory diseases. Results: Gas6 and its soluble receptor sAxl raised in mice models and TNF-a was more elevated in Gas6)/) mice than in wild-type (WT). Protein array showed that before and after LPS injection, titers of 62 cytokines were more elevated in plasma of Gas6)/) than WT mice. Endotoxemia-induced mortality was higher in Gas6)/), Axl)/), Tyro3)/) and Mertk)/) compared to WT mice and mortality subsequent to CLP was amplified in Gas6)/) mice. LPS-stimulated Gas6)/) macrophages produced more cytokines than WT macrophages. This production was dampened by recombinant Gas6. Phosphorylation of Akt in Gas6)/) macrophages was reduced, but p38 phosphorylation and NF-jB translocation were increased. In human, Gas6 raised in plasma after LPS (2 ng/kg). Gas6 and sAxl were higher in patients with severe sepsis than in healthy subjects or control patients, and there was a non-significant trend for higher Gas6 in the survival group. Conclusions: Our data point to Gas6 as a major modulator of innate immunity and provide thereby novel insights into the mechanism of sepsis. Thus Gas6 and its receptors might constitute potential therapeutic targets for the development of new immunomodulating drugs.

Vaccinia immune globulin: current policies, preparedness, and product safety and efficacy.

In 1980 the World Health Organization declared that smallpox was eradicated from the world, and routine smallpox vaccination was discontinued. Nevertheless, samples of the smallpox virus (variola virus) were retained for research purposes, not least because of fears that terrorist groups or rogue states might also have kept samples in order to develop a bioweapon. Variola virus represents an effective bioweapon because it is associated with high morbidity and mortality and is highly contagious. Since September 11, 2001, countries around the world have begun to develop policies and preparedness programs to deal with a bioterror attack, including stockpiling of smallpox vaccine. Smallpox vaccine itself may be associated with a number of serious adverse events, which can often be managed with vaccinia immune globulin (VIG). VIG may also be needed as prophylaxis in patients for whom pre-exposure smallpox vaccine is contraindicated (such as those with eczema or pregnant women), although it is currently not licensed in these cases. Two intravenous formulations of VIG (VIGIV Cangene and VIGIV Dynport) have been licensed by the FDA for the management of patients with progressive vaccinia, eczema vaccinatum, severe generalized vaccinia, and extensive body surface involvement or periocular implantation following inadvertent inoculation.

Autologous stem cell transplantation: leukapheresis product has anti-angiogenic effects in vivo correlating with neutrophil-derived VEGFR1.

BACKGROUND: High-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT) is used for the treatment of hemato-oncologic malignancies. In this study, we measured the effect of HDC/ASCT on plasma concentrations of antiangiogenic soluble vascular endothelial growth factor receptor 1 (sVEGFR1) and of leukapheresis products (LP) and patient serum on chick chorioallantoic (CAM) angiogenesis. MATERIALS AND METHODS: VEGFR1- and CD34-expressing cells of leukapheresis products were analyzed by flow cytometry. Alternatively spliced isoforms of VEGFR1 mRNA were quantified using reverse transcription PCR. RESULTS: Plasma concentrations of sVEGFR1 decreased after HDC, but significantly increased after ASCT. In the CAM assay, sera of patients elicited a proangiogenic effect before and after HDC, but a strong antiangiogenic response after ASCT, comparable to that of bevacizumab at therapeutic concentrations. LP contains high concentrations of sVEGFR1, and high density of VEGFR1(+) neutrophilic granulocytes, in which mRNA expression is shifted toward the soluble VEGFR1 isoform. CONCLUSION: Neutrophil-derived antiangiogenic sVEGFR1 within the LP may contribute to the therapeutic efficacy of ASCT.

Asphalt Cement Concrete Longitudinal Joint Adhesive Crafco PN 34524 (Iowa DOT New Product C-98-7), HR-2084, 2000

The joint between two lanes of asphalt pavement is often the first area of a roadway which shows signs of deterioration and requires maintenance. As the final lift of hot asphalt is being placed in a construction project, it is being forced p against the adjoining lane of cold asphalt, forming the longitudinal joint. The mating of the two lanes, to form a high quality seal, is often not fully successful and later results in premature stripping or raveling as water enters the unsealed joint. The application of a hot poured rubberized asphaltic joint sealant along the joint face in the final stage of construction should help to form a watertight joint seal. A new product, especially formulated for the longitudinal joint in asphalt pavements was proposed to improve joint sealing. The following describes the experimental application of the new product, Crafco, PN 34524.

Development of an Improved Agricultural-Based Deicing Product, TR-581, 2010

Snow and ice removal on public streets is a critical part of the work of departments of transportation in northern U.S. states, including Iowa. Iowa is also a state rich in agricultural resources, some of which undergo industrial processes that generate a number of byproducts, e.g., in converting corn to ethanol or soy to biodiesel. It would be desirable to find those that, with a minimum of additional processing, can be used as a deicing compound, either alone or in combination with products currently in use. The focus of this work is therefore to investigate by-products from agricultural processes that may be suitable for use as deicing applications. This topic has been investigated in the past by others, with many patented products described in the literature. An initial screening was carried out to assess the potential acceptability of selected commercial products, as well as a glycerol developed for this project. Based on the variety of parameters tested, the product combination that shows the greatest promise for future application consists of 80% glycerol with 20% NaCl.

Time-Temperature Strength-Reaction Product Relationships in Lime-Bentonite-Water Mixtures, HR-111, 1965

The interrelation of curing time, curing temperature, strength, and reactions in lime-bentonite-water mixtures was examined. Samples were molded at constant density and moisture content and then cured for periods of from 1 to 56 days at constant temperatures that ranged from 5C to 60C. After the appropriate curing time the samples were tested for unconfined compressive strength. The broken samples were then analyzed by x-ray diffractometer and spectrophotometer to determine the identity of the reaction products present after each curing period. It was found that the strength gain of lime-clay mixtures cured at different temperatures is due to different phases of the complex reaction, lime & clay to CSH(gel) to CSH(II) to CSH(I) to tobermorite. The farther the reaction proceeds, the higher the strength. There was also evidence of lattice substitutions in the structure of the calcium silicate hydrates at curing temperatures of 50C and higher. No consistent relationship between time, temperature, strength, and the S/A ration of reaction products existed, but in order to achieve high strengths the apparent C/S ration had to be less than two. The curing temperature had an effect on the strength developed by a given amount of reacted silica in the cured lime-clay mixture, but at a given curing temperature the cured sample that had the largest amount of reacted silica gave the highest strength. Evidence was found to indicate that during the clay reaction some calcium is indeed adsorbed onto the clay structure rather than entering into a pozzolanic reaction. Finally, it was determined that it is possible to determine the amount of silica and alumina in lime-clay reaction products by spectrophotometric analysis with sufficient accuracy for comparison purposes. The spectrophotometric analysis techniques used during the investigation were simple and were not time consuming.

SEPT4, a p53 target gene product, implicates p 53 in the regulation of exocytosis

Résumé : Le cancer, qui est responsable d'un quart des décès en Suisse, exhibe un état cellulaire désordonné, qui lui-même, est la conséquence d'un dérèglement des gènes. Le gène le plus fréquemment altéré, dans les cas de cancers humains, est p53. Ce gène encode un facteur de transcription, impliqué dans la régulation de nombreux gènes impliqués dans le cycle cellulaire, l'apoptose ou la différenciation. Notre laboratoire a récemment identifié seize nouveaux gènes, dont l'expression est régulée par p53, parmi lesquels sept4, su jet de cette thèse. La protéine 5EPT4 appartient à la famille des septines, qui est impliquée dans la cytokinèse. Dans ce travail, nous avons confirmé la régulation de l'expression de sept4 par p53 dans des tissus de souris, et étonnamment, seul un des deux promoteurs du gène sept4 est contrôlé par p53. En outre, l'approche immunohistologique nous a permis de supposer une implication de la protéine SEPT4 dans le mécanisme de l'exocytose. Cette hypothèse a été confirmée par l'interaction de SEPT4 avec la protéine syntaxine 1A, et par son activité inhibitrice sur la sécrétion stimulée. En élargissant l'étude de la protéine SEPT4, nous avons découvert que celle-ci avait comme partenaire fonctionnel, la protéine Pinl, une enzyme qui catalyse l'isomérisation cis-trans du lien peptidique précédant une proline. bans ce contexte, nous avons démontré que l'interaction entre ces deux protéines reposait sur le domaine WW de Pinl, un type de domaine reconnaissant les motifs phosphoséryl-prolyl et phosphothréonyl-prolyl. Ce dernier résultat nous a conduit à examiner la phosphorylation de 5EPT4. Nous avons démontré que la partie N-terminale de SEPT4 était phosphorylée par la kinase Cdk5. La co¬expression de Cdk5 et de SEPT4 stimule la dégradation de SEPT4, indépendamment de la voie du protéasome. Ainsi, l'ensemble de nos observations fournissent l'évidence de l'engagement de la protéine SEPT4 dans la régulation de l'exocytose, et soutiennent le rôle de p53 dans le contrôle de l'exocytose, via SEPT4, ce qui constituerait un nouveau rôle fonctionnel pour ce gardien du génome. Summary: Cancer, which is responsible for a quarter of the deaths in Switzerland, exhibits a disordered cellular state, which itself, is the consequence of an altered state of genes. The most frequently altered gene in human cancer is p53. This gene encodes a transcription factor, implicated in the regulation of numerous genes involved in cell cycle, apoptosis or differentiation. Our laboratory has recently identified sixteen new genes whose expression is regulated by p53, amongst them septin 4, which is the subject of this thesis. The SEPT4 protein belongs to the septin family which is implicated in cytokinesis. In the present work, we have confirmed the regulation of sept4 expression by p53 in mouse tissues, and surprisingly, only one of the two sept4 promoters is regulated by p53. In addition, the immunohistologic approach enabled us to suppose a role of SEPT4 in exocytosis. This assumption was confirmed by the interaction of SEPT4 with syntaxin 1A, and by its inhibiting activity on stimulated secretion. By widening the analysis of SEPT4, we identified Pin1 as an interacting protein. Pin1 is an enzyme which catalyzes the cis-trans isomerization of the peptide bond preceding a proline residue. In this context, we showed that the interaction between these two proteins depends on the WW domain of Pin 1. This domain has been shown to function as a phosphoserine- or phosphothreonine¬binding module. This last result prompted us to examine phosphorylation of SEPT4. We demonstrated that the N-terminal portion of SEPT4 was phosphorylated by the Cdk5 kinase. The co-expression of Cdk5 with 5EPT4 stimulates SEPT4 degradation, independently of the proteasome pathway. Thus, these observations provide evidence for the engagement of SEPT4 in the regulation of exocytosis, and supports the role of p53 in the control of exocytosis, via SEPT4, which constitutes a new functional role for this guardian of the genome.

Generic brands and product differentiation strategies

Generic or own brand products were initially only lesser expensive copies of the branded label alternative, but nowadays, pricing alone is not enough in order to survive in the Fast Moving Consumer Goods (FMCG) or Consumer Packaged Goods (CPG)markets. With this in mind manufacturers of generic brands have adapted to this rapidlygrowing niche by investing in design and marketing during the initial phase in order to be perceived as having a quality product comparable to that of the branded products. In addition, they have gone further ahead with a second phase and resorted to innovativeproduct differentiation strategies and even pure innovation in many cases. These strategies have granted generic brands constantly increasing market shares and a position of equals relative to national brands.Using previous analyses and case studies, this paper will provide conceptual and empirical evidence to explain the surprisingly fast growth and penetration of generic supermarket brands, which in their relatively short lifespan, have grown to rival the historical market leaders, the branded products. According to this analysis, the main conclusion is that the growth in generic brands can be explained not only by price competition, but also by the use of innovative product differentiation strategies.
