Identificação organizacional como principal estratégia de retenção de jovens numa empresa de consultoria de IT: construção de um plano de retenção para a empresa

The purpose of this project is to show that Organisational Identification can be used as a main strategy to retain young professionals in the IT Consulting business. At the end of the project, a Retention Plan is expected to be constructed for Company A. For data collection, 10 semi-structured individual interviews and 1 focus group of 5 people were conducted. The participants consisted of young people, who already are a part of the Academy Project at the company where the plan is to be implemented and who already are inserted in the job market. The empirical research methods used were qualitative, and two separate content analysis were conducted – one of them to evaluate the information obtained in the interviews and the other for the focus group. Based on the result analysis, we were able to understand that the young people involved value four dimensions: organisational identification with company A, their relationship with company B, salary and benefits and the balance between professional and social life. The conclusions drawn were fundamental to reach the main purpose of the project: the construction of a retention plan for young workers at company A.Este projeto tem como objetivo mostrar que a Identificação Organizacional pode ser usada como principal estratégia de Retenção de Jovens em Consultoria de IT. No final do projeto é esperada a Construção de um Plano de Retenção para a Empresa A. Para a recolha de dados foram realizadas 10 entrevistas individuais semiestruturadas e 1 focus group composto por 5 pessoas, a jovens que fazem parte do Projeto Academia da empresa de IT onde será implementado o plano e que atualmente já estão inseridos no mercado de trabalho. Os métodos de investigação empírica utlizados foram qualitativos e foram efetuadas duas análises de conteúdo separadamente, às informações recolhidas nas entrevistas e no "focus group". Através da análise dos resultados foi-nos possível perceber que os jovens dão valor a quatro dimensões: identificação organizacional com a empresa A, a relação que têm com a empresa B, remuneração e benefícios e equilíbrio entre a vida profissional e social. As conclusões retiradas foram fundamentais para atingir o objetivo principal do projeto: construção de um plano de retenção de jovens para a empresa A

Hidden costs of flexible work: Employers’ perception

In a context where labor flexibility is increasingly a choice for companies to reduce organizational costs and increase their competitiveness in the labor market, it is pertinent to study the nature of the motivations behind the use of FWA, as well as the advantages and disadvantages associated with these types of contract. This research, of a qualitative and exploratory nature, explores these dimensions by placing the employer at the center of the analysis, a poorly researched perspective. HR managers of companies in Portugal were interviewed (n=8). The empirical information, gathered from semi-directive interviews, suggested that the stable employment contract remains the most recurrent option, at about 77.5%. Flexible hiring, on the other hand, responds to the very particular needs of the company, namely changes in demand. Besides, the conversion of flexible contracts into stable ones appears, in some cases, as a reward for the good performance of the employees. Companies recognize the advantages of flexible contracts as well as some negative consequences. Although the recognition of hidden costs has not been explicit, there are indications of concerns such as workers' motivation. The results obtained may be useful for companies to consider their options as to the type of employment relationship they intend to implement, as well as to elucidate policymakers as to the factors that may influence companies' decisions. However, they should be analyzed with caution. The sample is small and includes only companies that have shown themselves to be available. Nevertheless, it opens space for future more extensive research.Num contexto em que a flexibilidade laboral constitui, cada vez mais, uma escolha das empresas no sentido de diminuir os custos organizacionais e aumentar a sua competitividade no mercado de trabalho, revela-se pertinente estudar a natureza das motivações por detrás da utilização de contratos de trabalho flexíveis, bem como as vantagens e desvantagens associadas a estes tipos de contrato. Esta pesquisa, de natureza qualitativa e exploratória, explora essas dimensões colocando o empregador no centro da análise, perspetiva escassamente investigada. Foram entrevistados gestores de RH de empresas em Portugal (n=8). A informação empírica, recolhida a partir de entrevistas semi-diretivas, sugeriu que o contrato de trabalho estável continua a ser a opção mais recorrente, em cerca de 77.5%. Já a contratação flexível responde a necessidades muito particulares da empresa, designadamente alterações na procura. Acresce que a transformação de contratos flexíveis para estáveis surge, em alguns casos, como recompensa do bom desempenho dos colaboradores. As empresas reconhecem vantagens dos contratos flexíveis, bem como algumas consequências negativas. Embora o reconhecimento de custos ocultos não tenha sido explícito, há indicações de preocupações como quanto à motivação dos trabalhadores. Os resultados obtidos podem ser úteis para as empresas equacionarem as suas opções quanto ao tipo de relação de emprego que pretendem implantar, bem como para elucidar os decisores políticos quanto aos fatores que podem influenciar as escolhas das empresas. Todavia, devem ser analisados com cautela. A amostra é pequena e inclui apenas empresas que se mostraram disponíveis. Apesar disso, abre espaço para futuras pesquisas mais abrangentes

Heterogeneous communication scheme for IoT smart nodes

There has been a rapid evolution in the area of the Internet of Things, and this means that a greater need for improved communications, for better device performance, is also in need. This dissertation presents a proposal for an efficient heterogeneous communication system that, with the help of Machine Learning algorithms, will be able to automatically predict, without human intervention, the best communication method to use. The goal of this system is to ensure that the user is always using the most appropriate technology for the situation and environment he is in, and to make the device experience the best possible. The system, which includes software and hardware, was developed to be easy to use and low-cost. An online platform was also developed, where the user can view and monitor the system in real time. In the platform it is possible to enter the various fields that are presented, that is, the characteristics of the environment in which the device is, and then the user can get information about the best technology to use, for this specific case. The effectiveness of the system developed was also studied and experimentally tested, and accuracy of between 94% and 96.78% could be observed depending on the scenario. The results obtained were explained in detail in this dissertation.Tem existido uma enorme evolução na área da Internet das Coisas isto faz com que também tenha começado a existir uma maior necessidade de melhorar as suas comunicações para um melhor desempenho dos dispositivos.

Centralidade urbana: configuração espacial e condições socioeconômicas na cidade de São Paulo, Brasil

Este artigo explora São Paulo, a maior cidade da América do Sul. O crescimento da cidade caracteriza-se por um deslocamento do centro urbano em direção ao sudoeste. Este teve consequências deletérias sobre o centro histórico, que sofreu uma deterioração do seu ambiente construído e um aumento da privação socioeconômica. Este artigo examina como a morfologia transformada de São Paulo no século XXI afetou a distribuição socioeconômica e a diversidade demográfica. Ele emprega uma abordagem da sintaxe espacial, que é um conjunto de técnicas e teoria que investiga as relações entre configuração espacial e os fenômenos socioeconômicos. Análises revelam que a morfologia de São Paulo apresenta um “colcha de retalhos”, que são morfologicamente diferenciados pela sua relação de escala com a estrutura urbana maior. As consequências socioeconômicas dessa fragmentação tem sido o aumento da diferenciação de classes sociais consistentes com a sua acessibilidade às concentrações de atividade que ocorrem em diferentes escalas urbanas.This paper explores São Paulo, the largest city in South America. The growth of the city has been characterized by a shift of the urban centre towards the southwest. This had deleterious consequences on the historic centre, which experienced a deterioration of its built environment and an increase in socio-economic deprivation. This paper examines how the transformed morphology of twenty-first century São Paulo affected its socio-economic distribution and demographic diversity. It employs theoretical and methodological space syntax approach, which is a set of techniques and theory that investigates relationships between spatial layout and socio-economic phenomena. The analysis found that the morphology of São Paulo presents a ‘patchwork’ of offset grids, which are morphologically differentiated by their scaled relationship to the larger urban structure. Socioeconomic consequences of this fragmentation have been to increase the differentiation of social classes consistent with their accessibility to concentrations of activity taking place at different scales.Peer Reviewe

a connection between science and mother tongue

UID/SOC/04647/2019The study plans of the courses for Primary School Teachers in the Lisbon Higher School of Education include a curricular unit designed "Projects of Curricular Integration between Science and Mother Tongue". Their main goal is to develop interdisciplinarity reflection, discussion and didactic proposals between these two subjects. In the final session of the unit, in the last two school years, a questionnaire about interdisciplinarity was administered to the 37 students that chose it, in order to identify, among other aspects, the advantages and potentialities of this type of knowledge articulation. Fourteen educational resources designed by the students to explore Nacional Tapada of Mafra were also analyzed. The results showed that the majority of the students tend to emphasize the importance of interdisciplinarity in promoting meaningful learning and in the perception that knowledge is interconnected. Concerning the educational resources, the students explore mainly scientific vocabulary and the use of description and expository text, regularly used in outdoor tasks.publishersversionpublishe

Unilateral Idiopathic Sensory Trigeminal Nerve Paralysis in a Dog

Background: A spayed-female mixed breed dog was presented due to 2 years reduced visual acuity in the left eye. The investigation revealed corneal melanosis, keratoconjunctivis sicca and loss of facial sensation in the same side. The aim of this report is to describe an unilateral idiopathic sensory trigeminal nerve paralysis and keratitis as consequence of corneal innervation loss was established. Unilateral sensory trigeminal nerve paralysis is a very rare lesion in dogs and causes are unclear.Case: A 5-year-old spayed-female mixed breed dog was presented with a history of two years reduced visual acuity in the left eye. The Schirmer tear test values (without use of topical anesthetic) were 11 and 17 mm/min in the left and right eye respectively. Fluorescein tests were negative for both eyes. All postural reactions and spinal reflexes were normal. Cranial nerve evaluation identified symmetrical facial muscles (temporalis, masseter), indicating no muscle atrophy and normal motor nucleus of the fifth nerve. Absent sensation at the upper and lower lips margins, cornea, eyelids (medial and lateral canthi) and sensation in left nasal side were noted. No palpebral reflex was noticed, but there was spontaneous blinking of eyelids, which indicated normal facial nerve function. All other cranial nerve reflexes including menace response, oculocephalic, and gag reflexes were normal. The owner declined further workup, including cerebrospinal fluid analysis and images studies. According to the clinical presentation and neurological findings, presumptive diagnosis of unilateral idiopathic sensory trigeminal nerve paralysis was established. The dog was observed over 18 months without any clinical improvement. The Schirmer tear test showed same values (12 mm/min) and the melanosis remained unchanged.Discussion: Lesions that affected trigeminal nerve, trigeminal ganglion, or trigeminal tract in the pons and medulla caused facial hypoalgesia or analgesia. The causes of trigeminal nerve damage included neoplasia, trauma, fracture of petrous temporal bone and inflammatory polyneuropathies, but the dog present no signals of these diseases. Trigeminal nerve lesions that affected ophthalmic nerve branch will result in loss of corneal sensation and loss of corneal and palpebral reflex as consequence. Paralysis of this branch cause degenerative changes in the cornea, as neurotrophic keratitis that result in edema and epitelial erosion. The Schirmer tear is the standard test to quantify aqueous tear production and the result (11 mm/min) in dog’s left eye is considered early or subclinical keratoconjunctivis sicca (KCS) sign. The pigmentation results from melanocytic cells migration from the limbal or perilimbal tissues. The keratitis can be active when followed by corneal vascularization, stromal inflammatory cell infiltration and granulation tissue formation. The etiology for idiopathic disease is unknown and isolated sensory trigeminal neuropathy have never been described in dogs. There is no definitive treatment and corticosteroid therapy did not appear to alter the course of the disease in dogs with idiopathic trigeminal neuritis therefore supportive treatment is indicated. The paralysis of trigeminal sensory ophthalmic and maxillary branches can result in corneal alterations

Optic disc detection in retinal images by pattern distance minimization

The retinal fundus photograph is widely used in the diagnosis and treatment of various eye diseases such as diabetic retinopathy and glaucoma. On the research work leading to automatic analysis of retinal images, the knowledge of the optic disc (OD) location is essential, and a new method to locate the optic disc automatically is proposed. We propose an algorithm for the detection of OD in the retina which takes advantage of the powerful preprocessing techniques such as the contrast enhancement, Gabor wavelet transform, mathematical morphology and Earth Mover’s distance as the matching process. Forty images of the retina from the DRIVE database were used to evaluate the performance of the method
