Avaliação de Desempenho: será um processo considerado como justo?

O presente estudo procura estabelecer a relação entre a Percepção de Justiça e Satisfação com o Sistema de Avaliação de Desempenho. A metodologia utilizada foi a quantitativa, pois permite validar a revisão da literatura efetuada, onde se procura analisar a relação entre a Percepção de Justiça e a Satisfação com o Sistema de Avaliação de Desempenho através de um conjunto de hipóteses que posteriormente serão testadas. Para se testar as hipóteses recolheu-se os dados através da adaptação de um questionário já aplicado em Portugal (Porfírio, 2006). O mesmo foi aplicado a 89 funcionários de uma empresa do ramo Transitário. Para o tratamento dos dados recolhidos vai ser utilizado o programa IBM SPSS Statistics 20. De acordo com os resultados obtidos verificou-se que existe uma relação positiva e significativa entre a Percepção de Justiça na dimensão Distributiva e a Satisfação com o Sistema de Avaliação de Desempenho. Não se tendo verificado o mesmo para a dimensão Procedimental. Em relação ao Big Five podemos constatar que é significativo e que exerce controlo entre a Percepção de Justiça Distributiva e a Satisfação com o Sistema de Avaliação de Desempenho, não se tendo comprovado o mesmo para a Percepção de Justiça Procedimental.

Description and Prediction of Freezing of Gait in Parkinson's Disease from Wearable Inertial Measurements Units

Parkinson's disease (PD) is a neuro-degenerative disorder, the second most common after Alzheimer's disease. After diagnosis, treatments can help to relieve the symptoms, but there is no known cure for PD. PD is characterized by a combination of motor and no-motor dysfunctions. Among the motor symptoms there is the so called Freezing of Gait (FoG). The FoG is a phenomenon in PD patients in which the feet stock to the floor and is difficult for the patient to initiate movement. FoG is a severe problem, since it is associated with falls, anxiety, loss of mobility, accidents, mortality and it has substantial clinical and social consequences decreasing the quality of life in PD patients. Medicine can be very successful in controlling movements disorders and dealing with some of the PD symptoms. However, the relationship between medication and the development of FoG remains unclear. Several studies have demonstrated that visual or auditory rhythmical cuing allows PD patients to improve their motor abilities. Rhythmic auditory stimulation (RAS) was shown to be particularly effective at improving gait, specially with patients that manifest FoG. While RAS allows to reduce the time and the effects of FoGs occurrence in PD patients after the FoG is detected, it can not avoid the episode due to the latency of detection. An improvement of the system would be the prediction of the FoG. This thesis was developed following two main objectives: (1) the finding of specifics properties during pre FoG periods different from normal walking context and other walking events like turns and stops using the information provided by the inertial measurements units (IMUs) and (2) the formulation of a model for automatically detect the pre FoG patterns in order to completely avoid the upcoming freezing event in PD patients. The first part focuses on the analysis of different methods for feature extraction which might lead in the FoG occurrence.

Étude longitudinale de l’impact de la satisfaction envers les avantages sociaux novateurs sur l’intention de rester chez les travailleurs du secteur des technologies de l’information et des communications

The objective of this thesis is to understand the impact of satisfaction with innovative benefits on the intention to stay of the information and communications technology industry (ICT) workers. In order to investigate this question, a general research hypothesis was presented based on a literature review and on Blau’s social exchange theory (1964) and Maslow’s theory of needs (1943). The general research hypothesis states that satisfaction with innovative benefits increases intention to stay through time. The data used in this thesis were collected as part of a larger research on the relationships between compensation, training and skills development and attracting and retaining key employees. The longitudinal data come from an office located in Montreal of a major international company from the ICT sector. The study population consists of workers newly hired between April 1st, 2009 and September 30th, 2010. The results confirm the research hypothesis showing that satisfaction with innovative benefits increase intention to stay through time. Among the various innovative benefits studied, the results indicate that it is the satisfaction with the gym at work that best predicts intention to stay of workers. Other innovative benefits significantly related to intention to stay are the games library, the lounge, the medical clinic and the library in the workplace. Also, longitudinal analyses reveal that it is mainly the differences between the individual characteristics of the employees who best explain intention to stay than the differences across time of the same worker. This thesis concludes by discussing the best way for industrial relations managers to use the results in order to retain their employees. Then, the limits of the study and some directions for further research are also presented.

Warranty servicing strategies to improve customer satisfaction

Customer satisfaction with a purchased product depends on its performance under warranty and during the remainder of its useful life. Dissatisfaction with an item is important to a manufacturer since it can lead to the loss of potential customers through the negative word-of-mouth effect as well as existing customers switching to a competitor. In this paper, we define satisfaction in terms of the likelihood of a customer not switching to a different manufacturer when a new item needs to be purchased. Manufacturers can use specific servicing strategies to reduce warranty costs and this topic has already been addressed in the literature without considering the effect of customer dissatisfaction. In this paper, we propose particular strategies that will increase customer satisfaction and we discuss methods for obtaining the optimal parameters of these strategies.

Longitudinal relationships among overweight, life satisfaction, and aspirations in young women

Objective: This study investigated associations of overweight status and changes in overweight status over time with life satisfaction and future aspirations among a community sample of young women. Research Methods and Procedures: A total of 7865 young women, initially 18 to 23 years of age, completed two surveys that were 4 years apart. These women provided data on their future life aspirations in the areas of further education, work/career, marital status, and children, as well as their satisfaction with achievements to date in a number of life domains. Women reported their height and weight and their sociodemographic characteristics, including current socioeconomic status (occupation). Results: Young women's aspirations were cross-sectionally related to BMI category, such that obese women were less likely to aspire to further education, although this relationship seemed explained largely by current occupation. Even after adjusting for current occupation, young women who were obese were more dissatisfied with work/career/study, family relationships, partner relationships, and social activities. Weight status was also longitudinally associated with aspirations and life satisfaction. Women who were overweight or obese at both surveys were more likely than other women to aspire to other types of employment (including self-employed and unpaid work in the home) as opposed to full-time employment. They were also less likely to be satisfied with study or partner relationships. Women who resolved their overweight/obesity status were more likely to aspire to being childless than other women. Discussion: These results suggest that being overweight/obese may have a lasting effect on young women's life satisfaction and their future life aspirations.

Prospective study of men's psychological and decision-related adjustment after treatment for localized prostate cancer

Objectives. To undertake a prospective longitudinal study to assess psychological and decision-related distress after the diagnosis of localized prostate cancer. Methods. A total of I 11 men (93% response rate) with localized prostate cancer were recruited from outpatient urology clinics and urologists' private practices. More than one half (56%) elected to undergo radical prostatectomy, 19% underwent external beam radiotherapy, and 25% chose watchful waiting. Men completed self-report measures before treatment and 2 and 12 months after treatment. The measures used included the University of California, Los Angeles, Prostate Cancer Index, International Prostate Symptom Score, Impact of Events Scale, Constructed Meaning Scale, Satisfaction with Life Scale, Health Care Orientation subscale, and Decisional Conflict Scale. Results. No statistically significant differences were found by medical treatment group in the psychological and decision-related adjustment at baseline or with time. Men who were undecided about their treatment choice had greater decisional conflict and a more negative healthcare orientation, but were not more psychologically distressed, compared with men who had decided. At diagnosis, 63% of men had high decision-related distress, and this persisted for 42% of men 12 months after treatment, despite high satisfaction with their treatment choice. At diagnosis, low-to-moderate psychological distress was most common, with distress decreasing after treatment. The overall quality of life was similar to community norms. Conclusions. The results of our study indicated that men who were undecided about what treatment to receive experienced greater decision-related distress. The final treatment choice was not related to psychological distress about prostate cancer. Psychological and decision-related distress decreased with time, independent of treatment modality. Interventions should target decision-related distress for all men and in-depth psychological support for those who experience ongoing difficulties. (C) 2004 Elsevier Inc.

Experience as a moderator of involvement and satisfaction on brand loyalty in a business-to-business setting 02-314R

This paper examines the relative influence of two key antecedents of brand loyalty-satisfaction and involvement and the moderating role of experience, using a sample of business buyers. The central argument of this paper is that the strength of the effect of these variables on attitudinal brand loyalty will vary with the level of customer experience with purchasing the service. Building on previous research which examined low-risk, customer product settings [Kim, J., Lim, J.S., & Bhargava, M. (1998). The role of affect in attitude formation: A classical conditioning approach. Journal of the Academy of Marketing Science 26 (2): pp. 143-152; Shiv, B., & Fedorikhin, A. (1999). Heart and mind in conflict: The interplay of affect and cognition in consumer decision-making. Journal of Consumer Research 26: 278], this study shows that for a high-risk setting, involvement with the service category will be more dominant in its influence on brand loyalty than satisfaction with the preferred brand. Furthermore, it was found that experience moderated the influence of involvement and satisfaction on attitudinal brand loyalty for a high-risk business-to-business service. This study provides new insights into the theory and practice of buyer behavior and business-to-business brands. Crown Copyright (C) 2004 Published by Elsevier Inc. All rights reserved.

Evaluating Patient Education Materials about Radiation Therapy

Targeted treatment education for cancer patients has the potential to promote adjustment through assisting patients to participate in treatment decision making, comply with treatment regimens and cope more effectively with treatment side effects. A quasi-experimental longitudinal pre-test post-test and follow-up design was used to assess the effect of a patient education video about radiation therapy on patients' psychological distress, knowledge about radiation therapy, self-efficacy about coping with treatment and physical symptoms. Patients with head and neck (n = 26) and breast cancer (n = 66) were recruited into the study and allocated into control and intervention groups. No significant differences were found between the control and intervention groups on any of the outcome variables. However, patients in the intervention group reported high levels of satisfaction with the video and all reported that they would recommend the video to other patients preparing for radiation therapy. As well, 90% of patients in the intervention group reported that some or all of the information in the video was new to them. Education materials that have excellent face validity and that are well received by patients may fail to produce significant change using standard controlled study designs. Future research in this area may need to consider alternative paradigms for evaluating the helpfulness of such materials. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.

The origin and evolution of the surfactant system in fish: Insights into the evolution of lungs and swim bladders

Several times throughout their radiation fish have evolved either lungs or swim bladders as gas-holding structures. Lungs and swim bladders have different ontogenetic origins and can be used either for buoyancy or as an accessory respiratory organ. Therefore, the presence of air-filled bladders or lungs in different groups of fishes is an example of convergent evolution. We propose that air breathing could not occur without the presence of a surfactant system and suggest that this system may have originated in epithelial cells lining the pharynx. Here we present new data on the surfactant system in swim bladders of three teleost fish ( the air-breathing pirarucu Arapaima gigas and tarpon Megalops cyprinoides and the non-air-breathing New Zealand snapper Pagrus auratus). We determined the presence of surfactant using biochemical, biophysical, and morphological analyses and determined homology using immunohistochemical analysis of the surfactant proteins (SPs). We relate the presence and structure of the surfactant system to those previously described in the swim bladders of another teleost, the goldfish, and those of the air-breathing organs of the other members of the Osteichthyes, the more primitive air-breathing Actinopterygii and the Sarcopterygii. Snapper and tarpon swim bladders are lined with squamous and cuboidal epithelial cells, respectively, containing membrane-bound lamellar bodies. Phosphatidylcholine dominates the phospholipid (PL) profile of lavage material from all fish analyzed to date. The presence of the characteristic surfactant lipids in pirarucu and tarpon, lamellar bodies in tarpon and snapper, SP-B in tarpon and pirarucu lavage, and SPs ( A, B, and D) in swim bladder tissue of the tarpon provide strong evidence that the surfactant system of teleosts is homologous with that of other fish and of tetrapods. This study is the first demonstration of the presence of SP-D in the air-breathing organs of nonmammalian species and SP-B in actinopterygian fishes. The extremely high cholesterol/disaturated PL and cholesterol/PL ratios of surfactant extracted from tarpon and pirarucu bladders and the poor surface activity of tarpon surfactant are characteristics of the surfactant system in other fishes. Despite the paraphyletic phylogeny of the Osteichthyes, their surfactant is uniform in composition and may represent the vertebrate protosurfactant.

Rehabilitation after total knee replacement via low-bandwidth telemedicine: the patient and therapist experience

After a total knee replacement, inadequate rehabilitation is associated with poor physical outcomes and a reduced longevity of the knee prosthesis. We have developed a low-bandwidth telemedicine system to enable rehabilitation services to be delivered directly to the home of patients in rural and remote areas. We have examined the experience of clinical physiotherapists and of 31 participants who received treatment via the system. High levels of satisfaction were reported by participants (mean responses >7 on a 10 cm visual analogue scale). The service was found to be effective, safe and easy to use, and it integrated well into current clinical practice. The study demonstrates the potential for delivering physiotherapy services via low-bandwidth Internet connections.

The relative benefits of endurance and strength training on the metabolic factors and muscle function of people with type 2 diabetes mellitus

Objective: To compare the effects of a 4-month strength training (ST) versus aerobic endurance training (ET) program on metabolic control, muscle strength, and cardiovascular endurance in subjects with type 2 diabetes mellitus (T2D). Design: Randomized controlled trial. Setting: Large public tertiary hospital. Participants: Twenty-two T21) participants (I I men, I I women; mean age +/- standard error, 56.2 +/- 1.1 y; diabetes duration, 8.8 +/- 3.5y) were randomized into a 4-month ST program and 17 T2D participants (9 men, 8 women; mean age, 57.9 +/- 1.4y; diabetes duration, 9.2 +/- 1.7y) into a 4-month ET program. Interventions: ST (up to 6 sets per muscle group per week) and ET (with an intensity of maximal oxygen consumption of 60% and a volume beginning at 15min and advancing to a maximum of 30min 3X/wk) for 4 months. Main Outcome Measures: Laboratory tests included determinations of blood glucose, glycosylated hemoglobin (Hb A(1c)), insulin, and lipid assays. Results: A significant decline in Hb A, was only observed in the ST group (8.3% +/- 1.7% to 7.1% +/- 0.2%, P=.001). Blood glucose (204 +/- 16mg/dL to 147 +/- 8mg/dL, P <.001) and insulin resistance (9.11 +/- 1.51 to 7.15 +/- 1.15, P=.04) improved significantly in the ST group, whereas no significant changes were observed in the ET group. Baseline levels of total cholesterol (207 +/- 8mg/dL to 184 +/- 7mg/dL, P <.001), low-density lipoprotein cholesterol (120 +/- 8mg/dL to 106 +/- 8mg/dL, P=.001), and triglyceride levels (229 +/- 25mg/dL to 150 +/- 15mg/dL, P=.001) were significantly reduced and high-density lipoprotein cholesterol (43 +/- 3mg/dL to 48 +/- 2mg/dL, P=.004) was significantly increased in the ST group; in contrast, no such changes were seen in the ET group. Conclusions: ST was more effective than ET in improving glycemic control. With the added advantage of an improved lipid profile, we conclude that ST may play an important role in the treatment of T2D.

An evaluation of a telephone-based postnatal support intervention for infant feeding in a regional Australian city

Background: Postnatal breastfeeding support in the form of home visits is difficult to accommodate in regional Australia, where hospitals often deal with harsh economic constraints in a context where they are required to provide services to geographically, dispersed consumers. This study evaluated a predominately telephone-based support service called the Infant Feeding Support Service. Methods: A prospective cohort design was used to compare data for 696 women giving birth in two regional hospitals (one public, one private) and participating in the support service between January and July 2003 with data from a cohort of 625 women who gave birth in those hospitals before the introduction of the support service. Each mother participating in the support service was assigned a lactation consultant. First contact occurred 48 hours after discharge, and approximately it weekly thereafter for 4 it weeks. Breastfeeding duration was measured at 3 months postpartum. Results: For women from the private hospital, the support service improved exclusive breastfeeding duration to 4.5 weeks postpartum, but these improvements were not evident at 3 months postpartum. No effects were observed for mothers from the public hospital. Quantitative and qualitative data demonstrated high levels of client satisfaction with the support service. Conclusions: This small-scale, predominately telephone-based intervention provided significant, although apparently context-sensitive, improvements to exclusive breastfeeding duration.
