Satisfação organizacional, identificação organizacional e intenção de turnover : estudo comparativo com uma amostra de trabalhadores do sector farmacêutico

Tese de mestrado, Psicologia (Secção de Psicologia dos Recursos Humanos, do Trabalho e das Organizações), Universidade de Lisboa, Faculdade de Psicologia, 2016Para fazer face à crise financeira que o país atravessa e ao aumento da concorrência e da exigência dos clientes, cada vez mais as organizações reconhecem que são os seus colaboradores que podem fazer a diferença. Neste cenário, torna-se importante investir no estudo de variáveis psicológicas, que permitam ampliar o conhecimento sobre o comportamento do indivíduo em contexto organizacional. O presente estudo tem como principal objetivo estudar a satisfação organizacional, a identificação organizacional e a intenção de turnover em trabalhadores do setor farmacêutico, bem como as relações entre estas variáveis. Pretende-se, ainda, comparar os níveis das variáveis referidas, em função da implementação ou não de práticas de recursos humanos. Para a recolha de dados, foram aplicados três instrumentos de medida a uma amostra de 123 colaboradores, os quais foram distribuídos por dois grupos: um, em que todas as práticas de recursos humanos foram implementadas, e outro, em que nem todas estas práticas foram implementadas. Os resultados evidenciam a existência de uma relação direta e significativa entre Satisfação Organizacional e Identificação Organizacional, de uma relação inversa e significativa entre Satisfação Organizacional e Intenção de Turnover, e entre Identificação Organizacional e Intenção de Turnover, e do papel mediador da Satisfação Organizacional na relação entre Identificação Organizacional e Intenção de Turnover. Verifica-se também que, a implementação de práticas de recursos humanos não tem influência significativa na satisfação e identificação organizacionais e na intenção de turnover. No final, são discutidos os principais contributos do estudo e apresentadas algumas limitações e sugestões de investigação.To deal with the financial crisis the country is currently facing and increasing competition and client’s demands, organizations are more and more acknowledging their employees as the ones that can make a difference. In this scenario, it becomes important to invest in studying psychological variables that allow us to expand our knowledge on how individuals behave in organizational contexts. The aim of this research is studying organizational satisfaction, organizational identification and turnover intention in pharmaceutical sector workers, as well as the interactions between those variables. It also intends to compare the levels of the referred variables, based on whether human resources practices were implemented. Regarding the data collection, three measuring instruments were applied to a sample of 123 employees that were separated into two groups: in one of them all the human resources practices were implemented, whilst in the other not all practices were implemented. The results point out a direct significant correlation between Organizational Satisfaction and Organizational Identification, an inverse significant correlation between Organizational Satisfaction and Turnover Intention and also between Organizational Identification and Turnover Intention, in which Organization Satisfaction seems to have a mediating role. The implementation of human resources practices doesn’t have a significant influence in organizational satisfaction and identification and turnover intention. At the end we discuss the main contributions of this study and present some limitations and suggestions for future investigations

Distributed active traction control system applied to the RoboCup middle size league

This work addresses the problem of traction control in mobile wheeled robots in the particular case of the RoboCup Middle Size League (MSL). The slip control problem is formulated using simple friction models for ISePorto Team robots with a differential wheel configuration. Traction was also characterized experimentally in the MSL scenario for relevant game events. This work proposes a hierarchical traction control architecture which relies in local slip detection and control at each wheel, with relevant information being relayed to a higher level responsible for global robot motion control. A dedicated one axis control embedded hardware subsystem allowing complex local control, high frequency current sensing and odometric information procession was developed. This local axis control board is integrated in a distributed system using CAN bus communications. The slipping observer was implemented in the axis control hardware nodes integrated in the ISePorto robots and was used to control and detect loss of for traction. %and to detect the ball in the kicking device. An external vision system was used to perform a qualitative analysis of the slip detection and observer performance results are presented

Novel magnetic stimulation methodology for low-current implantable medical devices

Recent studies highlight the ability of inductive architectures to deliver therapeutic magnetic stimuli to target tissues and to be embedded into small-scale intracorporeal medical devices. However, to date, current micro-scale biomagnetic devices require very high electric current excitations (usually exceeding 1 A) to ensure the delivery of efficient magnetic flux densities. This is a critical problem as advanced implantable devices demand self-powering, stand-alone and long-term operation. This work provides, for the first time, a novel small-scale magnetic stimulation system that requires up to 50-fold lower electric current excitations than required by relevant biomagnetic technology recently proposed. Computational models were developed to analyse the magnetic stimuli distributions and densities delivered to cellular tissues during in vitro experiments, such that the feasibility of this novel stimulator can be firstly evaluated on cell culture tests. The results demonstrate that this new stimulative technology is able to deliver osteogenic stimuli (0.1-7 mT range) by current excitations in the 0.06-4.3 mA range. Moreover, it allows coil designs with heights lower than 1 mm without significant loss of magnetic stimuli capability. Finally, suitable core diameters and stimulator-stimulator distances allow to define heterogeneity or quasi-homogeneity stimuli distributions. These results support the design of high-sophisticated biomagnetic devices for a wide range of therapeutic applications.This work was funded by the Portuguese Foundation for Science and Technology (FCT), through the grant references SFRH/BPD/117475/2016, SFRH/BD/129340/2017 and IF/01089/2015, and by the European Structural and Investment Funds, through the project reference POCI-01-0145-FEDER-031132 and POCI-01-0145-FEDER-007679.

Ehrharta longiflora Sm. y Pennisetum setaceum (Forsk.) Chiov., dos nuevas gramíneas exóticas para la isla de Madeira

El número de taxones introducidos y posiblemente introducidos en los archipiélagos de Madeira y Salvajes supone aproximadamente un 36% de su flora total, incluyendo 53 taxa de poáceas (sobre un total de 141 taxa de poáceas), constituyendo, de esta manera, la familia botánica con mayor número de taxa introducidos (38,4%). El género Ehrharta Thunb. comprende unas 35 especies, con una especie, E. longiflora Sm., registrada como introducida en Gran Canaria. El género Pennisetum Rich. incluye cerca de 80 especies, de las cuales un total de nueve especies están presentes en Macaronesia, de las que tres (P. clandestinum Hochst. & Chiov., P. purpureum Schum. y P. villosum R. Br. ex Fresen), se encuentran en el archipiélago de Madeira. Ehrharta longiflora Sm. y Pennisetum setaceum (Forssk.) Chiov. se citan en este trabajo por primera vez para la isla de Madeira, donde han sido encontradas en áreas perturbadas a bajas y medias altitudes. El hallazgo de varios individuos maduros en estado de flor/fruto de ambas especies sugiere que están totalmente naturalizadas. El trabajo discute la naturalización, la capacidad invasora y los impactos ecológicos generados por las mismas.The number of introduced, and possible introduced, taxa in the Madeira and Selvagens islands currently accounts for nearly 36% of the total flora of these archipelagos, including 53 Poaceae taxa (out of 141 Poaceae taxa), therefore constituting the family with the higher proportion of introduced taxa (38.4%). The genus Ehrharta Thunb. comprises about 35 species, with one species, E. longiflora Sm., recorded as introduced in Gran Canaria. The genus Pennisetum Rich. includes ca. 80 species of which a total of nine species are present in Macaronesia, with three: P. clandestinum Hochst. & Chiov., P. purpureum Schum. and P. villosum R. Br. ex Fresen, occurring in the Madeira archipelago. Ehrharta longiflora Sm. and Pennisetum setaceum (Forssk.) Chiov., are here recorded for the first time for the Madeira island, found in disturbed areas at low and medium altitudes. The finding of several mature and flowering/fructifying individuals of both species suggests a fully naturalized status. Naturalization, invasiveness and ecological impacts are discussed

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Dos nuevos taxa exóticos de helechos para la isla de Madeira (Portugal)

La flora vascular del archipiélago de Madeira incluye 74 taxones de pteridofitas. De ellos, ocho son endemismos exclusivos, otros ocho endemismos macaronésicos, siendo la gran mayoría, unos 44, especies nativas y 14 más son consideradas exóticas. El número total de taxones de plantas vasculares exóticas es de 401, lo que supone aproximadamente el 33% del total de la flora. La reciente detección de muchas especies de helechos totalmente naturalizadas es paralela a la que ocurre con otros grupos de plantas vasculares. En este trabajo se registra por primera vez la presencia de Pteris nipponica W.C. Shieh (syn. Pteris cretica L. var. albolineata Hooker) y Goniophlebium subauriculatum (Blume) C. Presl como nuevas especies naturalizadas para la isla de Madeira.The Madeira archipelago vascular flora includes 74 pteridophyte taxa. Of these, eight are exclusive endemics, eight are Macaronesian endemics, being the vast majority, 44, native and 14 referred as introduced taxa. The total number of alien vascular plant taxa is 401 (i.e. 33% of the total flora). The recent detection of several fully naturalized alien fern taxa is a process parallel to that observed in other groups of vascular plants. The occurrence of Pteris nipponica W.C. Shieh (syn. Pteris cretica L. var. albolineata Hooker) and Goniophlebium subauriculatum (Blume) C. Presl as new naturalized plants is recorded for the first time for the island of Madeira

Dynamic off-centering of Cr3+^{3+} ions and short-range magneto-electric clusters in in CdCr2_2S4_4

The cubic spinel CdCr$_2$S$_4$ gained recently a vivid interest, given the relevance of relaxor-like dielectric behavior in its paramagnetic phase. By a singular combination of local probe techniques namely Pair Distribution Function and Perturbed Angular Correlation we firmly establish that the Cr ion plays the central key role on this exotic phenomenon, namely through a dynamic off-centering displacement of its coordination sphere. We further show that this off centering of the magnetic Cr-ion gives rise to a peculiar entanglement between the polar and magnetic degrees of freedom, stabilizing, in the paramagnetic phase, short range magnetic clusters, clearly seen in ultra-low field susceptibility measurements. Moreover, the Landau theory is here used to demonstrate that a linear coupling between the magnetic and polar order parameters is sufficient to justify the appearance of magnetic cluster in paramagnetic phase of this compound. These results open insights on the hotly debated magnetic and polar interaction, setting a step forward in the reinterpretation of the coupling of different physical degrees of freedom

Early results of a distance learning paediatric surgery programme in Mozambique

Introduction: A pre-graduate training programme in paediatric surgery was applied to students in four medical schools of Mozambique. In this paper, we evaluate the early results of the programme. Materials and Methods: A pre-graduate training programme was developed and applied in two stages, theoretical education available at an online platform and a face-to-face session. To evaluate the programme, a diagnostic test was applied to all participants before the face-to-face session and, the same test, was applied again at the end of the session. Results: A total of 236 students participated in the programme. Forty-four per cent had a negative score on the diagnostic test. When the test was repeated, 91.9% had a positive score, and the difference between the scores in both tests reached statistical significance (P < 0.05). The participants who completed the first phase of the programme presented a higher median score in both tests (P < 0.05). Conclusions: The diagnostic tests allowed us to verify there was an increase in knowledge before and after the face-to-face session. There was also a significant difference between those participants who completed the online phase of the programme and those who did only the face-to-face session, which allows us to conclude that the online teaching programme was effective.info:eu-repo/semantics/publishedVersio
