Civil service reform trends in public personnel management: Experiences from the Commonwealth of the Bahamas

This study has explored the potential for implementing a merit-based public personnel system in The Bahamas, a former British colony in The Commonwealth Caribbean. Specifically, the study evaluated the use of merit-based public personnel management practices in areas of recruitment, selection, promotion, training and employee development and performance evaluation. Driving forces and barriers which impact merit system successes and failures as well as strategies for institutionalizing merit system practices are identified. Finally the study attempted to apply the developmental model created by Klingner (1996) to describe the stage of public personnel management in The Bahamas. The data for the study was collected through in-depth interviews with expert observers. ^

Development of ``HealthServe'': A measure of customer service orientation in healthcare

An assessment tool designed to measure a customer service orientation among RN's and LPN's was developed using a content-oriented approach. Critical incidents were first developed by asking two samples of healthcare managers (n = 52 and 25) to identify various customer-contact situations. The critical incidents were then used to formulate a 121-item instrument. Patient-contact workers from 3 hospitals (n = 102) completed the instrument along with the NEO-FFI, a measure of the Big Five personality factors. Concurrently, managers completed a performance evaluation scale on the employees participating in the study in order to determine the predictive validity of the instrument.^ Through a criterion-keying approach, the instrument was scaled down to 38 items. The correlation between HealthServe and the supervisory ratings of performance evaluation data supported the instrument's criterion-related validity (r =.66, p $<$.0001). Incremental validity of HealthServe over the Big Five was found with HealthServe accounting for 46% of the variance.^ The NEO-FFI was used to assess the correlation between personality traits and HealthServe. A factor analysis of HealthServe suggested 4 factors which were correlated with the NEO-FFI scores. Results indicated that HealthServe was related to Extraversion, Openness to Experience, Agreeableness, Conscientiousness and negatively related to Neuroticism.^ The benefits of the test construction procedure used here over the use of broad-based measures of personality were discussed as well as the limitations of using a concurrent validation strategy. Recommendations for future studies were provided. ^

Practical dynamic thermal management on Intel desktop computer

Fueled by increasing human appetite for high computing performance, semiconductor technology has now marched into the deep sub-micron era. As transistor size keeps shrinking, more and more transistors are integrated into a single chip. This has increased tremendously the power consumption and heat generation of IC chips. The rapidly growing heat dissipation greatly increases the packaging/cooling costs, and adversely affects the performance and reliability of a computing system. In addition, it also reduces the processor's life span and may even crash the entire computing system. Therefore, dynamic thermal management (DTM) is becoming a critical problem in modern computer system design. Extensive theoretical research has been conducted to study the DTM problem. However, most of them are based on theoretically idealized assumptions or simplified models. While these models and assumptions help to greatly simplify a complex problem and make it theoretically manageable, practical computer systems and applications must deal with many practical factors and details beyond these models or assumptions. The goal of our research was to develop a test platform that can be used to validate theoretical results on DTM under well-controlled conditions, to identify the limitations of existing theoretical results, and also to develop new and practical DTM techniques. This dissertation details the background and our research efforts in this endeavor. Specifically, in our research, we first developed a customized test platform based on an Intel desktop. We then tested a number of related theoretical works and examined their limitations under the practical hardware environment. With these limitations in mind, we developed a new reactive thermal management algorithm for single-core computing systems to optimize the throughput under a peak temperature constraint. We further extended our research to a multicore platform and developed an effective proactive DTM technique for throughput maximization on multicore processor based on task migration and dynamic voltage frequency scaling technique. The significance of our research lies in the fact that our research complements the current extensive theoretical research in dealing with increasingly critical thermal problems and enabling the continuous evolution of high performance computing systems.

Managing Quality in the Hospitality Industry:

In - Managing Quality In the Hospitality Industry – an observation by W. Gerald Glover, Associate Professor, Hospitality Management Program, Appalachian State University, initially Glover establishes: “Quality is a primary concern in the hospitality industry. The author sees problems in the nature of the way businesses are managed and discusses approaches to ensuring quality in corporate cultures.” As the title suggests, the author wants to point out certain discrepancies in hospitality quality control, as well as enlighten you as to how to address some of these concerns. “A discussion of quality presents some interesting dilemmas. Quality is something that almost everyone wants,” Assistant Professor Glover notes. “Service businesses will never admit that they don't provide it to their customers, and few people actually understand what it takes to make it happen,” he further maintains. Glover wants you to know that in a dynamic industry such as hospitality, quality is the common denominator. Whether it be hotel, restaurant, airline, et al., quality is the raison d’être of the industry. “Quality involves the consistent delivery of a product or service according to the expected standards,” Glover provides. Many, if not all quality deficiencies can be traced back to management, Glover declares. He bullet points some of the operational and guest service problems managers’ face on a daily basis. One important point of note is the measuring and managing of quality. “Standards management is another critical area in people and product management that is seldom effective in corporations,” says Glover. “Typically, this area involves performance documentation, performance evaluation and appraisal, coaching, discipline, and team-building.” “To be effective at managing standards, an organization must establish communication in realms where it is currently non-existent or ineffective,” Glover goes on to say. “Coaching, training, and performance appraisal are methods to manage individuals who are expected to do what's expected.” He alludes to the benefit quality circles supply as well. In addressing American organizational behavior, Glover postures, “…a realization must develop that people and product management are the primary influences on generating revenues and eventually influencing the bottom line in all American organizations.” Glover introduces the concept of pro-activity. “Most recently, quality assurance and quality management have become the means used to develop and maintain proactive corporate cultures. When prevention is the focus, quality is most consistent and expectations are usually met,” he offers. Much of the article is dedicated to, “Appendix A-Table 1-Characteristics of Corporate Cultures (Reactive and Proactive. In it, Glover measures the impact of proactive management as opposed to the reactive management intrinsic to many elements of corporate culture mentality.

(Figure 2) Mean discharge per day (total and baseflow part) of the San Francisco River and daily precipitation at station ECPL (Planta), in 2007

We investigated controls on the water chemistry of a South Ecuadorian cloud forest catchment which is partly pristine, and partly converted to extensive pasture. From April 2007 to May 2008 water samples were taken weekly to biweekly at nine different subcatchments, and were screened for differences in electric conductivity, pH, anion, as well as element composition. A principal component analysis was conducted to reduce dimensionality of the data set and define major factors explaining variation in the data. Three main factors were isolated by a subset of 10 elements (Ca2+, Ce, Gd, K+, Mg2+, Na+, Nd, Rb, Sr, Y), explaining around 90% of the data variation. Land-use was the major factor controlling and changing water chemistry of the subcatchments. A second factor was associated with the concentration of rare earth elements in water, presumably highlighting other anthropogenic influences such as gravel excavation or road construction. Around 12% of the variation was explained by the third component, which was defined by the occurrence of Rb and K and represents the influence of vegetation dynamics on element accumulation and wash-out. Comparison of base- and fast flow concentrations led to the assumption that a significant portion of soil water from around 30 cm depth contributes to storm flow, as revealed by increased rare earth element concentrations in fast flow samples. Our findings demonstrate the utility of multi-tracer principal component analysis to study tropical headwater streams, and emphasize the need for effective land management in cloud forest catchments.

Infoestrutura: um sistema em nuvem para prover contexto como serviço no cenário de internet das coisas integrado a ambientes veiculares

Through numerous technological advances in recent years along with the popularization of computer devices, the company is moving towards a paradigm “always connected”. Computer networks are everywhere and the advent of IPv6 paves the way for the explosion of the Internet of Things. This concept enables the sharing of data between computing machines and objects of day-to-day. One of the areas placed under Internet of Things are the Vehicular Networks. However, the information generated individually for a vehicle has no large amount and does not contribute to an improvement in transit, once information has been isolated. This proposal presents the Infostructure, a system that has to facilitate the efforts and reduce costs for development of applications context-aware to high-level semantic for the scenario of Internet of Things, which allows you to manage, store and combine the data in order to generate broader context. To this end we present a reference architecture, which aims to show the major components of the Infostructure. Soon after a prototype is presented which is used to validate our work reaches the level of contextualization desired high level semantic as well as a performance evaluation, which aims to evaluate the behavior of the subsystem responsible for managing contextual information on a large amount of data. After statistical analysis is performed with the results obtained in the evaluation. Finally, the conclusions of the work and some problems such as no assurance as to the integrity of the sensory data coming Infostructure, and future work that takes into account the implementation of other modules so that we can conduct tests in real environments are presented.

Promoção, vencimento e avaliação de desempenho do professor do ensino fundamental: o PCCR da rede municipal de ensino de Natal/RN (2004-2010)

This study is about the enhancement of the elementary school in Natal/RN, (PCCR - Law No. 058/2004), concerning to the horizontal promotion through the performance evaluation. It uses as reference the education policy on the legislative field hegemony and the managerial model. The analysis of the teacher´s valorization is based on the policy of Funds (Fundef and Fundeb) in the Brazilian social and educational agenda. The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010).The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010). The thesis argues for the necessity to adopt a direct relationship between career development and horizontal promotion for more others fifteen classes, no matter to any conditioning variables. In addition, the performance shall be evaluated by interval of 25 years to reach at least the provisions decided in the law, which determines the salary adjustment in 5% at every two years, as pointed at the PCCR, about teachers remuneration, and teachers qualifications. A work of a bibliographic and a documental review about the education funding with the purpose of enhancement of educational work, career concepts, and also promotion and evaluation performance as well was performed based on experts authors in this field. The survey was organized with the aim of articulating quantitative and qualitative information, analyzing data from the teacher's salary - payrolls and paychecks - also applying a questionnaire. After the implementation of the PCCR, it was found that the wage indices for horizontal promotion during the teaching career are tied to a strategy for evaluating the performance which disqualifies the teacher‟s salaries in a minimum percentage of 25% (up to 25 years) and there are also elements that disturb the promotion strategy. The national minimum wage was set in three salaries by the PSPN Lei nº11.738/2008 but it never reaches the three salaries at Natal/RN educational system.Otherwise, the elements that structure the horizontal promotion in fifteen classes, throughout the career, flout the minimum years of teaching work, long established in 25 years. In addition, changes in terms in the salary increase depend on individual efforts by professional development through titration. Concerning to the career, despite of the category approving its PCCR, neither this instrument nor the Funds Policy managed to establish regulations were able to cope effective rules for valuing the teachers in the educational district system. It is necessary to ensure, in percentage terms and financial, the real remuneration of teachers with the attainment of horizontal promotion, reviewing the elements that structure the career and the determinants of performance evaluation.

Benchmarking e regulação do setor de distribuição de energia elétrica nacional: proposta para avaliação dos custos operacionais eficientes

In Brazil, the National Agency of Electric Energy (ANEEL) represents the energy regulator. The rates review have been one of its main tasks, which establish a pricing practice at a level to cover the efficient operating costs and also the appropriate return of the distributors investments. The changes in the procedures to redefine the efficient costs and the several studies on the methodologies employed to regulate this segment denote the challenge faced by regulators about the best methodological strategy to be employed. In this context, this research aims to propose a benchmarking evaluation applied to the national regulation system in the establishment of efficient operating costs of electricity distribution utilities. The model is formulated to promote the electricity market development, partnering with government policies ant to society benefit. To conduct this research, an integration of Data Envelopment Analysis (DEA) with the Stochastic Frontier Analysis (SFA) is adopted in a three stages procedure to correct the efficiency in terms of environmental effects: (i) evaluation by means of DEA to measure operating costs slacks of the utilities, in which environmental variables are omitted; (ii) The slacks calculated in the first stage are regressed on a set of environmental variables by means of SFA and operating costs are adjusted to account the environmental impact and statistical noise effects; and, (iii) reassess the performance of the electric power distribution utilities by means of DEA. Based on this methodology it is possible to obtain a performance evaluation exclusively expressed in terms of management efficiency, in which the operating environment and statistical noise effects are controlled.

Avaliação da toxicidade subcrônica e reprodutiva do extrato seco de pericarpo de passiflora edulis variedade flavicarpa degener em ratos

The pericarp of Passiflora edulis var. flavicarpa Degener is now being investigated for medicine purposes. There are no reports about it toxicity. The aim of the present study was investigate the sub chronic toxicity in male rats and reproductive toxicity in pregnant rats and exposed fetuses of an extract obtained by infusion of the pericarp in water (1:3 m/v;100o C, 10 min). The extract composition was evaluated by tube reactions and thin lawyer chromatography (TLC). Adult male rats (n=8) were treated with 300 mg/kg of the extract, by gavage, during 30 days and pregnant rats (n=7) from gestation day 0 to day 20. Control received tap water (1 mL). Water and food intakes and body weight gain were recorded. At day 29 of treatment the sexual behavior of the males was analyzed and then half of males from each group received cyclophosphamide (50 mg/kg, i.p.) to (anti)genotoxic assessment in bone marrow. At day 30, males were anesthesized for parameters collection. At day 20 of gestation, the dams were anesthesized for reproductive performance evaluation. The fetal analysis was conducted by visceral and skeletal. Phytochemical analysis revealed the presence of flavonoids, unspecific alkaloids, phenols and triterpenic compounds. Statistical analysis revealed absence of significant differences between experimental and control. This study suggest that the aqueous extract obtained from pericarp of P. edulis var. flavicarpa Degener was not able to promote toxic effects in rats. Cytotoxicity was evaluated with the PCE/NCE ratio (NCE=normochromatic erythrocytes). Statistical analysis (mean ± SEM) revealed absence of changes in the frequency of MNPCE (negative control: 3.26±0.42; positive control: 11.72±1.02; negative experimental: 4.02±0.13; positive experimental: 10.47±0.87) or cytotoxicity (negative control: 0.37±0.08; positive control: 0.23±0.05; negative experimental: 0.37±0.07; positive experimental: 0.23±0.02). This study suggests that the extracts showed no (anti)genotoxic and no cytotoxic activities under the experimental conditions.

A simulação como método de ensino de habilidades no curso de medicina: relato de uma experiência com punção lombar

The teaching of the lumbar puncture (LP) technique with simulator is not well systematized in the curricula of medical schools. Studies show that training in the simulator provides learning technical skills, acquisition and retention of knowledge, improve self-confidence of the learner and enables the transfer to clinical practice. We intend this study to introduce simulated training in LP in medical course at the Universidade Federal do Rio Grande do Norte evaluating the experience taking into account quantitative aspects (performance on standardized tests) and qualitative (perception of the students regarding the method and the teaching process learning). The study was conducted in two phases. In the first phase practical training in PL was introduced in the 3rd year of medical school. Seventy-seven students were trained in small groups, guided by a checklist developed in the model Objective Structured Assessment of Technical Skill (OSATS), at this moment they knew they were not under performance evaluation. They were also asked whether they had prior chances to make an LP in patients. At the end of the first phase the students evaluated training in the following areas: teaching technique, simulator realism, time available per group, number of participants per group and relevance to medical practice. In the second phase, two years later, 18 students trained in first stage performed a new LP on the mannequin simulator, and its performance was evaluated through the same checklist of training in order to verify the technical retention. In addition, they answered a multiple choice test about practical aspects of the LP technique. Each participant received individual feedback on their performance at the end of their participation in the study. In the first phase of the study we found that only 4% of students had performed a lumbar puncture in patients until the 3rd year. The training of LP technique with simulator mannequin was considered relevant and the teaching methods was thoroughly evaluated. In the second phase, all participants were successful in implementing the lumbar puncture on the mannequin simulator, compliance with the most steps in a reasonable time, suggesting that would be able to perform the procedure in a patient.

Estudo da influência de sistemas microemulsionados na molhabilidade de arenitos e na recuperação avançada de petróleo

Sandstone-type reservoir rocks are commonly responsible for oil accumulation. The wettability is an important parameter for the physical properties of the container, since it interferes in characteristics such as relative permeability to the aqueous phase, residual oil distribution in the reservoir, operating characteristics with waterflood and recovery of crude oil. This study applied different types of microemulsion systems - MES - in sandstone reservoirs and evaluated their influences on wettability and residual oil recovery. For this purpose, four microemulsion were prepared by changing the nature of ionic surfactants (ionic and nonionic). Microemulsions could then be characterized by surface tension analysis, density, particle diameter and viscosity in the temperature range 30° C to 70° C. The studied oil was described as light and the sandstone rock was derived from the Botucatu formation. The study of the influence of microemulsion systems on sandstone wettability was performed by contact angle measurements using as parameters the rock treatment time with the MES and the time after the brine surface contact by checking the angle variation behavior. In the study results, the rock was initially wettable to oil and had its wettability changed to mixed wettability after treatment with MES, obtaining preference for water. Regarding rock-MES contact time, it was observed that the rock wettability changed more when the contact time between the surface and the microemulsion systems was longer. It was also noted only a significant reduction for the first 5 minutes of interaction between the treated surface and brine. The synthesized anionic surfactant, commercial cationic, commercial anionic and commercial nonionic microemulsion systems presented the best results, respectively. With regard to enhanced oil recovery performance, all systems showed a significant percentage of recovered oil, with the anionic systems presenting the best results. A percentage of 80% recovery was reached, confirming the wettability study results, which pointed the influence of this property on the interaction of fluids and reservoir rock, and the ability of microemulsion systems to perform enhanced oil recovery in sandstone reservoirs.

Estratégia de capacitação pedagógica do residente: uma perspectiva para melhoria do ensino na Universidade Federal do Rio Grande do Norte

Studies have shown that resident informally plays the role of teacher. It is estimated that up to 25% of the residents of the time is devoted to teaching, mainly contributing as a facilitator, however, almost the entire medical residency programs in Brazil did not offer teacher training during residency education. This paper aims to introduce educational content initiation to teaching as part of the training of resident physician inserted in residency program of the University Hospital Onofre Lopes (HUOL). It is an exploratory, descriptive and prospective study in HUOL the Federal University of Rio Grande do Norte. Three steps were developed: preparation and planning of a pedagogic course, associated with a motivating technical content (basic and advanced life support); second stage, testing of pedagogical model for medical students; and finally, replication to residents. The interventions were made two practice stations life support with performance evaluation in practical activity through OSPE (Objective Structured Practical Examination). The techniques presented teachings were one-minute preceptor and feedback. Data collection was conducted through a structured evaluation form during the life support stations and at the end of the course, and analyzed using descriptive statistics. The results showed that the feedback and one minute preceptor were considered important for teaching and learning for more than 85% of participants. The feedback from evaluators practices stations added information about the performance and were held appreciatively way, according to 100% of the participants. Positive aspects highlighted by the participants were related to educational content, especially the participants of the first intervention. The time of the lectures of motivating technical content was the most repeated negative. Based on the good acceptance of pedagogical contents, this pioneer teacher training strategy was included in the formal residency program in Cardiology of our institution. It is considered therefore that the educational training model with motivating technical content was feasible and had a good evaluation and acceptance by most participants in both interventions. Thus, we believe that the educational content can be inserted in the formal curriculum of medical residency of other programs at HUOL through the training model developed in this study.

Proposta de um sistema de avaliação de desempenho para o Restaurante Universitário da UFRN

The aim of this study was to propose a Performance Evaluation System for outsourced employees of the University Restaurant of the Federal University of Rio Grande do Norte to supply the lack of evaluative instruments. According to Provision of Services Contract nº050/2010 and nº055/2011 of FURN with SAFE LOCAÇÃO DE MÃO DE OBRA LTDA ME, it is the hired company to promote periodic functional performance evaluation of the outsourced employees, but this is not done. The performance evaluation process serves to evaluate if the employees are making their tasks according to the organizations’ objectives and goals, besides that helps to find service failures and capacity of employees demands, thus contributing to improve work conditions and the global performance of the organizations. To elaborate the proposal of evaluation, it was chosen an action research with the participation of all stakeholders, employees and managers from UR. On data collect, first, outsourced employees and management servers were interviewed, in order to raise existing perceptions about performance evaluation aspects. From these data and the work routine observation, a proposal of performance evaluation was elaborated, that was appreciated, criticized and adjusted by the actors involved (employees and managers) to the final formulation of the instrument. This study also presents the necessary steps to the implementation of the Performance Evaluation System. The proposed Performance Evaluation System can be applied to the FURN assuming this process, after modification of contract terms and the approval by the ADCON. It also can serve as an example to others units that works with the provision of outsourced services, enabling so the performance evaluation to be part of the management policy of all people working in FURN.
