This article aims to evaluate the production line automation projects developed by Brazilian and Colombian companies from the Project Management perspective, through the analysis of the application degree of PMBOK processes, to understand how formal techniques are being employed in these countries and also to identify improvement opportunities, when necessary. Data were collected through a survey. The similarity index between the ten processes, with the highest application degree in the Brazilian and Colombian samples, was 70%. For the processes with the lowest application degree, the similarity index was 60%. No similar study was found in the literature. 相似文献

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm3 (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm3 (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm3 (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited. 相似文献

This study investigated how industrial salespeople gain the trust of their customers. Results show that trust increases as the customer gains the impression that the salesperson is dependable, honest, competent, customer oriented, and likeable. Based on the results, a general model of trust building is suggested. 相似文献

An ideal Kyoto protocol: emissions trading, redistributive transfers and global participation 总被引:3,自引:0,他引:3
We demonstrate that an interregional policy scheme featuringtrading of carbon dioxide emissions, redistributive resourcetransfers and global participation, a scheme which we call IdealKyoto Protocol, yields an efficient equilibrium allocationfor a global economy. An altruistic international agencysay,the Global Environment Facilityshould operate the resourcetransfer mechanism. In addition, regional governments shouldbe able to make independent policy commitments regarding howto control regional emissions of carbon dioxide in anticipationof the redistributive transfers. Our efficiency result suggeststhat the USA should be bribed to reverse its decisionof not participating in the Kyoto Protocol. 相似文献

A Cross-Country Database for Sector Investment and Capital 总被引:1,自引:0,他引:1

This article presents a new database of investment and capitalin agriculture, manufacturing, and the overall economy. It covers62 industrial and developing countries for the years 196792.A common method is used in the calculations to facilitate comparisonsacross countries and sectors. The sensitivity of the calculationsto choices of parameters and estimation methods is tested. Collectively,the data show that as economies grow, capital stocks accumulate,but the composition of capital changes. Together and individually,capital stocks in agriculture and manufacturing constitute asmaller share of the total capital stock than they did 20 yearsago. Capital-labor ratios show that agriculture has become morecapital intensive in most countries. The composition of agriculturalcapital has changed as well; capital from investments in orchardsand livestock has declined relative to capital from fixed investmentsin machinery, irrigation, and buildings. 相似文献

Despite the growing interest in supply chain management (SCM), there is little literature on the abilities practicing logisticians need to work in a SCM world. This paper studies these SCM abilities using two complementary methods: survey research and qualitative research interviews (case studies). The surveys yielded importance ratings of 45 SCM skill areas and a three‐factor skill model (interpersonal/managerial, quantitative/technological, and SCM core). Teamwork emerged as the skill area rated most important for SCM. Moreover, the case studies discovered additional critical skill areas for SCM such as gathering and sharing information. The interviews also enabled deeper understanding of skills within organizational contexts. 相似文献

Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information. 相似文献

This article explores the strategic importance of information systems for social control of networked services on urban and regional scales, and the nature of the information required for that purpose. The standard indicators of infrastructure coverage – by and large based on the number and encompassment of connections – no longer respond to the real conditions of supply and consumption. The technological and managerial innovations in flow control and dispatch, along with the effects of combined access to multi‐mode networks, render the evaluation of services’ connectivity considerably more complex than it used to be in the past. Private domination over the supply structure of these services tends to make the political struggle for equitability more dependent on the technical reliability of information than it could have been under the model of state supply. Networked services’ management has evolved to a more demand‐oriented structure, but this structure has so far reproduced the structural inequalities of Brazilian society in favor of powerful stakeholders, e.g. large consumers. The potential for more democratic control associated with this new balance between supply and demand in networked services can only evolve if more vulnerable social groups have access to sound technological and managerial information. To support this idea the article shows the importance of connectivity indicators in determining the effective access to networked utilities in the Metropolitan Area of São Paulo, in contrast to the traditional indicators of services’ coverage. Cet article explore l’importance stratégique des systémes d’information pour le contrôle social des services de réseaux au niveau urbain et régional, et la nature de l’information nécessaire pour cela. Les indicateurs habituels du niveau d’information sur l’infrastructure – généralement basés sur le nombre et la compréhension des relations – ne répondent plus aux conditions réelles de provision et de consommation. Les nouveautés de technologie et de gestion dans le contrôle du mouvement et dans les expéditions, ainsi que les effets de l’accés joint aux réseaux à modes multiples, rendent l’évaluation des liens entre les services beaucoup plus complexe que précédemment. La domination de la structure de provision de ces services par le domaine privé a tendance à rendre la lutte politique pour la justice plus dépendante de la fiabilité des informations qu’elle aurait pu l’? tre dans le modéle de provision par l’état. La gestion des services de réseaux a évolué vers une structure orientée vers la demande, mais jusqu’à présent cette structure a reproduit les inégalités structurelles de la société brésilienne qui favorise des détenteurs de pouvoir, par exemple les gros consommateurs. Les possibilités d’un contrôle plus démocratique associéà cet équilibre nouveau entre la provision et la demande dans les services de réseaux ne peut se développer que si les groupes sociaux les plus vulnérables ont accés à une information technologique et gestionnaire fiable. Pour soutenir cette opinion, l’article démontre l’importance des indicateurs de rapports pour déterminer des conditions d’accés efficaces aux entreprises de service de réseaux dans la région métropolitaine de Sao Paulo, au contraire des indicateurs traditionnels de l’information des services. 相似文献

This research theorizes that sellers of durable goods can utilize inferences about the buyer's willingness to pay based not only on her decision to trade in the old good but also on its characteristics. We find empirical support for this theory using transaction data for new car purchases. The results support the notion that dealers infer a higher willingness to pay and charge higher prices to consumers who trade in a used vehicle than to those who do not. We also find that dealers charge even higher prices to those consumers who trade in used cars that are similar to the new one. 相似文献
