A segurança dos consumidores

The present report, about consumer’s safety, shows the development of the knowledge on this particular subject and the actions carried out by entities that fight for the protection of consumer’s rights. The internship was based on the knowledge acquirement on the theoretical and practical aspects of the fight lead by the Direção Geral do Consumidor, together with other entities, towards the elimination or solely the reduction of risks caused by some products and services made available for the consumers or put on the market. During the internship, I counted with the support of my supervisor in the DGC, Dr. Ana Catarina Fonseca and, for the writing of the report, I had the help of my thesis advisor, Dr. Jorge Morais Carvalho, whenever I needed constructive criticism. My participation on the creation of the informative brochures about consumer’s safety, and the study of the legislation used by the DGC on the daily work, enabled me, effectively, to consolidate my guiding principles as a future professional on the matters of the creation of entities, private and public, which aim to ensure the protection of consumers’s rights, informing them of the possible risks or solving the already existing problems, removing dangerous products and services from the market.The report clarifies the action of the DGC on the protection of consumer’s safety, and enables some knowledge on the relations between the entities that work for the protection of the consumers and the market operators and on their work on identifying dangerous products and warning the consumers about it. The final part of this report contains information that allows us to form an idea of the importance that consumer safety has had in Cape Verde, compared with the laws of Portugal on the matter.

Engenheiros portugueses no século XVIII: as suas "geometrias especulativas"

O século XVIII Português foi, à semelhança do resto da Europa, fértil em alterações académicas, científicas e ideológicas. O desenvolvimento da ciência e da técnica, o surgimento das primeiras máquinas, impulsionou a área do saber, que atualmente chamamos de engenharia. Em Portugal (à época ainda um império do qual fazia parte, entre outros, o Brasil), as escolas técnicas e militares consolidam-se e surgem vários engenheiros e militares de renome cujas obras se difundem pelo reino. Manuel de Azevedo Fortes (1660-1749), engenheiro-mor do reino Português, publicou, em 1728 e 1729, os dois tomos de uma das suas obras maiores, O Engenheiro Português, obra dedicada à formação dos engenheiros na Academia Militar de Lisboa.. A primeira parte deste tratado aborda os conhecimentos matemáticos que Azevedo Fortes considera essenciais na formação dos engenheiros. Na sua Geometria Especulativa, um manuscrito datado de 1724, aborda os elementos de geometria e trigonometria, sem esquecer as suas aplicações. O Brigadeiro José Fernandes Pinto Alpoim (1700-1765), engenheiro que se destacou na arquitetura e fortificação do Brasil no século XVIII, publicou o Exame de Artilheiros em 1744 e Exame de Bombeiros em 1748, obras contendo os princípios da geometria e da trigonometria e as suas aplicações à engenharia militar que se destinavam ao ensino dos militares na Academia Militar do Rio de Janeiro, onde era professor. Nesta comunicação analisaremos a matemática, em particular a geometria, presente nestas obras, salientando não só os conteúdos abordados mas a ênfase dada às aplicações desses conteúdos nos contextos militares da época.

Occupational stress and coping among portuguese military police officers

This study describes the professional experience of military police officers from the Portuguese Republican National Guard (N = 95). We focused on the main sources and consequences of stress and the coping strategies used to deal with stress. The evaluation protocol included one closed-ended question and four open-ended questions. Data analysis of meaningful text segments was conceptually based and data categorization followed deductive content analysis. Results allowed the identification of 483 meaning units. Factors intrinsic to the job and the relationships at work were the main stressors referred by participants. The consequences of stressors were evident at an individual level, affecting family, psychological, and physical/health domains. The coping strategies used to deal with the main source of stress in the professional career were focused on problem solving (e.g., active confrontation) and emotional regulation (e.g., situation acceptance). Practical implications and future avenues of research with these professionals are discussed.

Morfossintaxe em Fernão de Oliveira (1536)

É objetivo deste ensaio mostrar que Fernão de Oliveira, tendo-se esforçado por não ficar muito preso aos modelos latinos, traçou as linhas mestras da gramática stricto sensu (ou morfossintaxe) do português do séc. XVI, isto é, identificou as categorias gramaticais que funcionam efetivamente nesta língua.

Relative growth and morphological sexual maturity of Chasmagnathus granulatus (Crustacea, Varunidae) from a mangrove area in southeastern Brazilian coast

The relative growth and morphological sexual maturity of Chasmagnathus granulatus Dana, 1851 are presented for the first time to a mangrove population. The crabs were obtained during low tide periods, in the mangrove of Jabaquara Beach, Paraty, Rio de Janeiro, Brazil. All crabs in intermolt stage were sexed and had their body parts measured as follows: body height (BH), carapace length (CL) and width (CW), major cheliped propodus height (PH) and length (PL) for each sex, gonopod length (GL) and abdomen width (AW) for males and females, respectively. The relative growth was described using the allometric equation y=ax b and the size at onset sexual maturity was achieved using the software Mature I. The size of specimens ranged from 4.1 mm to 39.5 mm CW. The growth pattern was different between sexes in the cheliped relationships; the relationships BH vs. CW evidenced positive allometry for juveniles; PL vs. CW and PH vs. CW positive allometry for most crabs except juvenile females; AW vs. CW and GL vs. CW evidenced positive allometry for juveniles and isometry for adults. The relationships that best indicated the change from the juvenile to the adult phase were PH vs. CW for males and AW vs. CW for females. The size in which 50% of males from this population are mature is at 19.7 mm of CW (F=144.14; p<0.05) and for females it is at 19.2 mm of CW (F=166.54; p<0.05). The sizes obtained in this mangrove population are larger than those from previous studies, that could be attributed to a species plasticity concerning the habitat structure.

The relative growth and sexual maturity of the freshwater crab Dilocarcinus pagei (Brachyura, Trichodactylidae) in the northwestern region of the state of São Paulo

The aim of the present study was to determine the size at sexual maturity in the freshwater crab Dilocarcinus pagei Stimpson, 1861, from a population located in Mendonça, state of São Paulo, Brazil. The crabs were sampled monthly (July 2005 to June 2007), at Barra Mansa reservoir. The specimens were captured manually or in sieves passed through the aquatic vegetation. The crabs were captured and separated by sex based on morphology of the pleon and on the number of pleopods. The following dimensions were measured: carapace width (CW); carapace length (CL); propodus length (PL); and abdomen width (AW). The morphological analysis of the gonads was used to identify and categorize individuals according to their stage of development. The morphological maturity was estimated based on the analysis of relative growth based on the allometric equation y = ax b. The gonadal maturity was based on the morphology of the gonads by the method CW50 which indicates the size at which 50% of the individuals in the population showed gonads morphologically mature to reproduction. The biometric relationships that best demonstrated the different patterns of growth for the juvenile and adult stages were CW vs. PL for males and CW vs. AW for females (p<0.001). Based on these relationships, the estimated value to morphological sexual maturity was 21.5 mm (CW) in males and 19.7 mm (CW) in females. The determination of the size at sexual maturity and the adjustment of the data based on the logistic curve (CW50) resulted in a size of 38.2 mm for males and 39.4 mm for females (CW). Based on the data obtained for sexual maturity for D. pagei, we can estimate a minimum size for capture of 40 mm (CW). This minimum size allows at least half of the population to reproduce and retains the juveniles and a portion of the adults in the population.

Extracción de parámetros de un resonador FBAR por optimización

L’objectiu d’aquest projecte que consisteix a elaborar un algoritme d’optimització que permeti, mitjançant un ajust de dades per mínims quadrats, la extracció dels paràmetres del circuit equivalent que composen el model teòric d’un ressonador FBAR, a partir de les mesures dels paràmetres S. Per a dur a terme aquest treball, es desenvolupa en primer lloc tota la teoria necessària de ressonadors FBAR. Començant pel funcionament i l’estructura, i mostrant especial interès en el modelat d’aquests ressonadors mitjançant els models de Mason, Butterworth Van-Dyke i BVD Modificat. En segon terme, s’estudia la teoria sobre optimització i programació No-Lineal. Un cop s’ha exposat la teoria, es procedeix a la descripció de l’algoritme implementat. Aquest algoritme utilitza una estratègia de múltiples passos que agilitzen l'extracció dels paràmetres del ressonador.

L'autoetnografia com a memòria de trànsit

Projecte realitzat en el Departament de dibuix de la Facultat de Belles Arts, a la Universitat de Barcelona, durant el segon curs de Doctorat, en el seminari que a càrrec de Fernando Hernandez on treballem l’ Autoetnografia Narrativa. Aquesta és una investigació que no té un caràcter individual marcat tan sols per la meva veu, sinó que més aviat la configuren també tots els companys de Seminari, amb ells i a través d’ells he aconseguit aprendre molts factors que intento quedin reflectits en el texte que presento i que treballo des de l’Educació Artística i la Cultura Visual. Durant aquest any me n’he adonat de què l’aprenentatge es realitza i té molt a veure amb les vivències que cada un de nosaltres construeix en societat, en elles centro les següents pàgines que per mí són l’inici d’un recorregut cap a un nou coneixement. Intento en tot moment tenir present el grup amb el qual he tingut la possibilitat de treballar durant aquest any i des del qual he pogut treballar-me com a subjecte educadora. D’aquesta manera i des de mí presento la meva contribució a n’aquest construir aprenentatge en societat, a partir de la següent narració.

Non-cooperative incentives to share knowledge in competitive environments

In this paper we study a model where non-cooperative agents may exchange knowledge in a competitive environment. As a potential factor that could induce the knowledge disclosure between humans we consider the timing of the moves of players. We develop a simple model of a multistage game in which there are only three players and competition takes place only within two stages. Players can share their private knowledge with their opponents and the knowledge is modelled as in uencing their marginal cost of e¤ort. We identify two main mechanisms that work towards knowledge disclosure. One of them is that before the actual competition starts, the stronger player of the rst stage of a game may have desire to share his knowledge with the "observer", be- cause this reduces the valuation of the prize of the weaker player of that stage and as a result his e¤ort level and probability of winning in a ght. Another mechanism is that the "observer" may have sometimes desire to share knowledge with the weaker player of the rst stage, because in this way, by increasing his probability of winning in that stage, he decreases the probability of winning of the stronger player. As a result, in the second stage the "observer" may have greater chances to meet the weaker player rather than the stronger one.
