O impacto do PADCT na química e engenharia química

Among all activities related to the management of science and technology in Brazil, program monitoring and evaluation is certainly one of the less developed and most needed. There are no universal methodologies that can be applied. In essence programs can be evaluated by relating their achievements to pre-established goals. A second strategy is to compare programs similar in nature, utilizing as reference common indicators. Finally programs can be evaluated by their socio-economic impact comparing investments to outcomes. All strategies mentioned require appropriate program design monitoring and expert independent evaluation. In Brazil as in many other countries including developed ones this activity is complicated by the fact that programs vary widely in their scope and goals. In Brazil program designs often do not specify clearly their purposes and output indicators, many are not monitored properly which makes evaluation difficult. Consequently science and technology programs are difficult to be compared to each other, and even evaluated on the basis of pre-established goals. In PADCT monitoring and evaluation proved to be the most challenging activities. Two lessons however were learnt. One is that the process of monitoring and evaluation has to be continuously exposed to criticism to be perfected; and the second is that the evaluation process must not be exhausted shortly after investments since translation of scientific knowledge into industrial applications may prove to be a lengthy process. In this exercise we certainly do not pretend to evaluate the QEQ subprogram but to organize some of the information produced by different sources related to this subject, including the PADCT administration. We use somewhat each strategy described: compare the outputs of the QEQ to predetermined proposed goals (particularly in PADCT II), compare the QEQ to other PADCT subprograms, and specify some outputs in terms of technological and industrial applications. Finally, we utilize this opportunity to discuss science and technology M&E in general and the complexity of developing this area in Brazil.

Desenvolupament d'un sistema de transferència de software per una placa entrenadora

El departament d’electrònica i telecomunicacions de la Universitat de Vic ha dissenyat un conjunt de plaques entrenadores amb finalitat educativa. Perquè els alumnes puguin utilitzar aquestes plaques com a eina d’estudi, és necessari disposar d’un sistema de gravació econòmic i còmode. La major part dels programadors, en aquest cas, no compleixen amb aquests requeriments. L’objectiu d’aquest projecte és dissenyar un sistema de programació que utilitzi la comunicació sèrie i que no requereixi d'un hardware ni software específics. D’aquesta manera, obtenim una placa autònoma i un programador gratuït, de muntatge ràpid i simple d’utilitzar. El sistema de gravació dissenyat s’ha dividit en tres blocs. Per una banda, un programa que anomenem “programador” encarregat de transferir codi de programa des de l’ordinador al microcontrolador de la placa entrenadora. Per altra banda, un programa anomenat “bootloader”, situat al microcontrolador, permet rebre aquest codi de programa i emmagatzemar-lo a les direccions de memòria de programa corresponents. Com a tercer bloc, s’implementa un protocol de comunicació i un sistema de control d’errors per tal d’assegurar una correcta comunicació entre el “programador” i el “bootloader”. Els objectius d’aquest projecte s’han complert i per les proves realitzades, el sistema de programació ha funcionat correctament.

Estudi sobre el perfil de persones grans amb dependència del servei d'ajuda a domicili del Consell Comarcal d'Osona i el tipus de suport formal i informal

The aim of this study is to determine the profile of dependent elderly people users of the home care services (SAD) of the regional council in Osona (Consell Comarcal d´Osona) , and the characteristics of formal and informal types of support they use. Methodology. An observational study of a transversal format has been carried out, with retrospective and descriptive purposes. The target population is 63 people (26 men and 37 women) included in the program of the regional SAD They have a recognized dependence grade approved by the law 39 /2006, December 14th , promoting the individual autonomy and care of elderly people in a dependent situation. The data were collected by social workers of basic social services, first with a home visit and followed by handed out questionnaires, specifically designed for this study, in order to obtain information on socio-demographic characteristics, and the type of support formal and informal. The obtained results on the SAD users are women in a 58.7% and a 41.3 % are men. The 84% of the total sampling are 80 years old and more, being the average age of 85.2 years old. 45% of them are married, 41% are widows and widowers and 14% are single. 54% are rated with severe dependence (grade II), 42.8% with high dependence (grade III). 86% live accompanied. 100% have an informal caregiver and a 95% of the times, the caregiver is a relative who in 73% of the cases the dedication time is permanent. The coverage of the SAD has an average of 4.27 hours per week and per user. The formal services most used are the technical (62%), also the assessment of an occupational therapist at home (57%) and the telecare service in a (56%). Conclusions. The SAD is used primarily for women in an advanced age and severe dependence. The informal assistance structures have an informal caregiver, being a member of the family mostly, living with the dependent, and mainly in a permanent dedication basis. The SAD has a varied intensity in each case. The formal support services complementary to the SAD, are largely used in all cases.

Estudi comparatiu de la qualitat de vida dels discapacitats intel·lectuals i del desenvolupament en els centres penitenciaris de Catalunya

El present estudi té com a objectiu principal conèixer la qualitat de vida que presenten les persones amb discapacitat intel·lectual i del desenvolupament (DID) que es troben complint condemna en els centres penitenciaris de Catalunya. També pretén explorar i descriure les característiques sociodemogràfiques i criminològiques dels interns amb DID que es troben ubicats als diferents centres penitenciaris, i a diferents unitats o mòduls residencials, així com comparar la qualitat de vida dels interns que estan en el Departament d’Atenció Especialitzada per la DID (DAE-DID) del Centre Penitenciari de Quatre Camins, en funcionament des de juny del 2013, amb la d’altres interns amb DID que es troben complint condemna a d’altres centres penitenciaris de Catalunya, i amb els quals s’intervé de forma menys intensiva. També s’analitzaran les diferències en la qualitat de vida dels DID que estan a presó i els DID amb trastorns de conducta que estan ingressats en centres residencials del medi comunitari. La mostra es va composar de 185 subjectes. Els professionals que tenen contacte amb ells van respondre l’Escala GENCAT (Verdugo, Arias, Gómez, Schalock, 2009). Les diferències trobades en aquest estudi indiquen que els interns amb DID que resideixen al DAE i aquells interns dels quals es té sospita de presència de discapacitat i que no es troben atesos pel programa Accepta presenten un nivells de qualitat de vida similars i significativament superiors als d’aquells interns amb DID atesos pel programa Accepta, apuntant en la línia que els interns ja diagnosticats amb DID estan millor si s’ubiquen en mòduls específics, al marge del funcionament ordinari del centre. Malgrat això, el nivell de qualitat de vida que presenten aquests dos grups no és superior a aquell que presenten els interns sense discapacitat. Tanmateix, el nivell de qualitat de vida dels discapacitats a presons és superior al d’aquelles persones discapacitades que es troben ingressades a centres de la xarxa comunitària. En l’estudi s’apunten alguns possibles factors que poden estar influenciant aquest resultat.

Kustannukset ja kannattavuus RFID- ja toiminnanohjausjärjestelmien integrointiprojektissa

Maailmantalouden jyrkkä lasku vuonna 2008 ajoi yritykset säästökuurille. Säästöjä pyritään saamaan esimerkiksi automatisoimalla toimintoja. Yksi tapa luoda kustannussäästöjä on käyttää RFIDteknologiaa varastoinnin toimien tehostukseen. Tämän tutkimuksen pääasiallisena tavoitteena on ollut rakentaa yksinkertainen laskentamalli RFID- ja toiminnanohjausjärjestelmien integrointiprojektin kustannusten ja kannattavuuden laskemiseen. Toisena tavoitteena on ollut selvittää, mitkä tekijät vaikuttavat investoinnin kannattavuuteen. Tutkimus rajattiin tarkastelemaan varaston saapuvan tavaran vastaanoton prosessia ja sen toimintojen automatisointia RFID-järjestelmän avulla. Laskentamalli muodostuu kolmesta osasta: investoinnin kokonaiskustannusten arvioinnista, investoinnista saatavien kustannussäästöjen arvioinnista ja kannattavuuslaskelmista. Investointien kokonaiskustannusten arviointia varten rakennettiin luettelo yleisimmistä kustannuslajeista. Investoinnista saatavien kustannussäästöjen arviointi tehtiin analysoimalla nykyprosesseja ja etsimällä niistä toimintoja, jotka tehostuvat RFID-järjestelmän avulla. Varsinaisina kannattavuuslaskentamenetelminä käytettiin investoinnin takaisinmaksuajan menetelmää sekä pääoman tuottoasteen menetelmää. Tutkimuksen tuloksena todettiin rakennetun laskentamallin soveltuvan hyvin investoinnin kustannusten ja kannattavuuden arviointiin. Samalla havaittiin yrityksen toimialan, saapuvien lähetysten määrän ja lähetysten rivimäärän vaikuttavan merkittävästi RFID- jatoiminnanohjausjärjestelmän integrointiprojektin kannattavuuteen.

Tool-supported invariant-based programming

The development of correct programs is a core problem in computer science. Although formal verification methods for establishing correctness with mathematical rigor are available, programmers often find these difficult to put into practice. One hurdle is deriving the loop invariants and proving that the code maintains them. So called correct-by-construction methods aim to alleviate this issue by integrating verification into the programming workflow. Invariant-based programming is a practical correct-by-construction method in which the programmer first establishes the invariant structure, and then incrementally extends the program in steps of adding code and proving after each addition that the code is consistent with the invariants. In this way, the program is kept internally consistent throughout its development, and the construction of the correctness arguments (proofs) becomes an integral part of the programming workflow. A characteristic of the approach is that programs are described as invariant diagrams, a graphical notation similar to the state charts familiar to programmers. Invariant-based programming is a new method that has not been evaluated in large scale studies yet. The most important prerequisite for feasibility on a larger scale is a high degree of automation. The goal of the Socos project has been to build tools to assist the construction and verification of programs using the method. This thesis describes the implementation and evaluation of a prototype tool in the context of the Socos project. The tool supports the drawing of the diagrams, automatic derivation and discharging of verification conditions, and interactive proofs. It is used to develop programs that are correct by construction. The tool consists of a diagrammatic environment connected to a verification condition generator and an existing state-of-the-art theorem prover. Its core is a semantics for translating diagrams into verification conditions, which are sent to the underlying theorem prover. We describe a concrete method for 1) deriving sufficient conditions for total correctness of an invariant diagram; 2) sending the conditions to the theorem prover for simplification; and 3) reporting the results of the simplification to the programmer in a way that is consistent with the invariantbased programming workflow and that allows errors in the program specification to be efficiently detected. The tool uses an efficient automatic proof strategy to prove as many conditions as possible automatically and lets the remaining conditions be proved interactively. The tool is based on the verification system PVS and i uses the SMT (Satisfiability Modulo Theories) solver Yices as a catch-all decision procedure. Conditions that were not discharged automatically may be proved interactively using the PVS proof assistant. The programming workflow is very similar to the process by which a mathematical theory is developed inside a computer supported theorem prover environment such as PVS. The programmer reduces a large verification problem with the aid of the tool into a set of smaller problems (lemmas), and he can substantially improve the degree of proof automation by developing specialized background theories and proof strategies to support the specification and verification of a specific class of programs. We demonstrate this workflow by describing in detail the construction of a verified sorting algorithm. Tool-supported verification often has little to no presence in computer science (CS) curricula. Furthermore, program verification is frequently introduced as an advanced and purely theoretical topic that is not connected to the workflow taught in the early and practically oriented programming courses. Our hypothesis is that verification could be introduced early in the CS education, and that verification tools could be used in the classroom to support the teaching of formal methods. A prototype of Socos has been used in a course at Åbo Akademi University targeted at first and second year undergraduate students. We evaluate the use of Socos in the course as part of a case study carried out in 2007.

Photosynthetic performance of mangroves Rhizophora mangle and Laguncularia racemosa under field conditions

In mature mangrove plants Rhizophora mangle L. and Laguncularia racemosa Gaerth. growing under field conditions, photosystem 2 (PS2) photochemical efficiency, determined by the ratio of variable to maximum fluorescence (Fν/Fm), increased during the day in response to salinity in the rainy seasons. During the dry season, fluorescence values (Fo) were higher than those observed in rainy season. In addition, Fo decreased during the day in both season and species, except for R. mangle during the dry season. A positive correlation among Fν/Fm and salinity values was obtained for R. mangle and L. Racemosa during the dry and rainy seasons, showing that photosynthetic performance is maintained in both species under high salinities. Carotenoid content was higher in L. Racemosa in both seasons, which represents an additional mechanism against damage to the photosynthetic machinery. The chlorophyll content was not affected by salinity in either species.

Solar drying of jack fruit almonds

Dryers heated by solar energy have been constructed and used in drying whole and half jack fruit almonds. The samples were dried during the day in direct sun and in the conventional solar dryer prepared for this purpose. Another piece of equipment was built for reception and accumulation of sun energy in a body of water, which was used as a heat source for night drying. The drying with the sun energy was compared with artificial drying. The jack fruit almonds were dried whole, half, with pellicle and without it. The storage of solar energy in water was technically viable for use in night drying. The drying by combining solar dryers in the day and night periods were completed in approximately 35 hours, and were equivalent to artificial drying between 40ºC and 70ºC. Almond cut in half and the pellicle removed reduced the drying time.

Sivistyksestä sivilisaatioon. Kulttuurikäsitys J. V. Snellmanin historiallisessa ajattelussa

From Bildung to Civilisation. Conception of Culture in J. V. Snellman’s Historical Thinking The research explores Johan Vilhelm Snellman’s (1806–1881) conception of culture in the context of his historical thinking. Snellman was a Finnish, Swedish-speaking journalist, teacher and thinker, who held a central position in the Finnish national discourse during the nineteenth century. He has been considered as one of the leading theorists of a Finnish nation, writing widely about the themes such as the advancement of the national education, Finnish language and culture. Snellman is already a widely studied person in Finnish intellectual history, often characterised as a follower of G. W. F. Hegel’s philosophical system. My own research introduces a new kind of approach on Snellman’s texts, emphasising the conceptual level of his thought. With this approach, my aim is to broaden the Finnish research tradition on conceptual history. I consider my study as a cultural history of concepts, belonging also to the field of intellectual history. My focus is on one hand on the close reading of Snellman’s texts and on the other hand on contextualising his texts to the European intellectual tradition of the time. A key concept of Snellman’s theoretical thinking is his concept of bildning, which can be considered as a Swedish counterpart of the German concept of Bildung. The Swedish word incorporated all the main elements of the German concept. It could mean education or the so-called high culture, but most fundamentally it was about the self-formation of the individual. This is also the context in which Snellman’s concept of bildning has often been interpreted. In the study, I use the concept of bildning as a starting point of my research but I broaden my focus on the cognate concepts such as culture (kultur), spirit (anda) and civilisation. The purpose of my study is thus to illustrate how Snellman used and modified these concepts and from these observations to draw a conclusion about the nature of his conception of culture. Snellman was an early Finnish philosopher of history but also interested in the practice of the writing of history. He did not write any historical presentations himself but followed the publications in the field of history and introduced European historical writing to the Finnish, Swedish-speaking reading audience in his newspapers. The primary source material consists of different types of Snellman’s texts, including philosophical writings, lecture material, newspaper articles and private letters. I’m reading Snellman’s texts in the context of other texts produced both by his Finnish predecessors and contemporaries and by Swedish, German and French writers. Snellman’s principal philosophical works, Versuch einer spekulativen Entwicklung der Idee der Persönlichkeit (1841) and Läran om staten (1842), were both written abroad. Both of the works were contributions to contemporary debates on the international level, especially in Germany and Sweden. During the 1840s and 1850s Snellman had two newspapers of his own, Saima and Litteraturblad, which were directed towards the Swedish-speaking educated class. Both of the newspapers were very popular and their circulations were among the largest of their day in Finland. The topics of his articles and reviews covered literature, poetry, philosophy and education as well as issues concerning the economic, industrial and technical development in Finland. In his newspapers Snellman not only brought forth his own ideas but also spread the knowledge of European events and ideas to his readers. He followed very carefully the cultural and political situation in Western Europe. He also followed European magazines and newspapers and was well acquainted with German, French and also English literature – and of course Swedish literature to with which he had the closest ties. In his newspapers Snellman wrote countless number of literary reviews and critics, introducing his readers to European literature. The study consists of three main chapters in which I explore my research question in three different, yet overlapping contexts. In the first of these chapters, I analyse Snellman’n theoretical thinking and his concepts of bildning, kultur, anda and civilisation in the context of earlier cultural discourse in Finland as well as the tradition of German idealistic philosophy and neo-humanism. With the Finnish cultural discourse I refer to the early cultural discussion in Finland, which emerged after the year 1809, when Finland became an autonomous entity of its own as a Grand Duchy of Russia. Scholars of the Academy of Turku opened a discussion on the themes such as the state of national consciousness, the need for national education and the development of the Finnish language as a national language of Finland. Many of these academics were also Snellman’s teachers in the early years of his academic career and Snellman clearly formulated his own ideas in the footsteps of these Finnish predecessors. In his theoretical thinking Snellman was a collectivist; according to him an individual should always be understood in connection with the society, its values and manners, as well as to the traditions of a culture where an individual belongs to. In his philosophy of the human spirit Snellman was in many ways a Hegelian but his notion of education or ‘bildning’ includes also elements that connect him with the wider tradition of German intellectual history, namely the neo-humanist tradition and, at least to some extent, to the terminology of J. G. Herder or J. G. Fichte, for example. In this chapter, I also explore Snellman’s theory of history. In his historical thinking Snellman was an idealist, believing in the historical development of the human spirit (Geist in German language). One can characterise his theory of history by stating that it is a mixture of a Hegelian triumph of the spirit and Herderian emphasis on humanity (Humanität) and the relative nature of ‘Bildung’. For Snellman, the process of ‘bildning’ or ‘Bildung’ is being realised in historical development through the actions of human beings. Snellman believed in the historical development of the human civilization. Still Snellman himself considered that he had abandoned Hegel’s idea about the process of world history. Snellman – rightly or wrongly – criticised Hegel of emphasising the universal end of history (the realisation of the freedom of spirit) at the expense of the historical plurality and the freedom of each historical era. Snellman accused Hegel of neglecting the value and independency of different historical cultures and periods by imposing the abstract norm, the fulfilment of the freedom of spirit, as the ultimate goal of history. The historicist in Snellman believed in the individuality of each historical period; each historical era or culture had values, traditions and modes of thought of its own. This historicist in Snellman could not accept the talk about one measure or the end of history. On the other hand Snellman was also a universalist. He believed that mankind had a common task and that task was the development of ‘Bildung’, freedom or humanity. The second main chapter consists of two parts. In the first part, I explore the Finnish nationalistic discourse from the cultural point of view by analysing the notions such as a nation, national spirit or national language and showing how Snellman formulated his own ideas in a dialogic situation, participating in the Finnish discourse but also reacting to international discussions on the themes of the nation and nationality. For Snellman nationality was to a great extent the collective knowledge and customs or practices of the nation. Snellman stated that nationality is to be considered as a form of ‘bildning’. This could be seen not simply as affection for the fatherland but also for the mental identity of the nation, its ways of thinking, its practices, national language, customs and laws, the history of the nation. The simplest definition of nationality that Snellman gives is that nationality is the social life of the people. In the second part of the chapter I exam Snellman’s historical thinking and his understanding about historical development, interaction between different nations and cultures in the course of history, as well as the question of historical change; how do cultures or civilisations develop and who are the creators of culture? Snellman did not believe in one dominating culture but understood the course of history as a dialogue between different cultures. On the other hand, his views are very Eurocentric – here he follows the ideas of Hegel or for example the French historian François Guizot – for Snellman Europe represented the virtue of pluralism; in Europe one could see the diversity of cultures which, on the other hand, were fundamentally based on a common Christian tradition. In the third main chapter, my focus is on the writing of history, more precisely on Snellman’s ideas on the nature of history as a science and on the proper way of writing historical presentations. Snellman wrote critics on the works of history and introduced his readers to the writing of history especially in France, Sweden and German-speaking area – in some extend also in Britain. Snellman’s collectivistic view becomes evident also in his reviews on historical writing. For Snellman history was not about the actions of the states and their heads, nor about the records of ruling families and battles fought. He repeatedly stressed that history is a discipline that seeks to provide a total view of a phenomenon. A historian should not only collect information on historical events, since this information touches only the surface of a certain epoch or civilisation; he has to understand an epoch as totality. This required an understanding about the major contours in history, connections between civilisations and an awareness of significant turning points in historical development. In addition, it required a holistic understanding about a certain culture or historical era, including also the so-called inner life of a specific nation, a common people and their ways of life. Snellman wrote explicitly about ‘cultural history’ in his texts, referring to this kind of broad understanding of a society. In historical writing Snellman found this kind of broader view from the works of the French historians such as François Guizot and Jules Michelet. In all of these chapters, I elaborate the conceptual dimension of Snellman’s historical thinking. In my study I argue that Snellman not only adopted the German concepts of Bildung or Kultur in his own thinking but also developed the Swedish concepts in a way that include personal and innovative aspects. Snellman’s concept of bildning is not only a translation from ‘Bildung’ but he uses the Swedish concept in a versatile way that includes both the moral aspect of human development and social dimension of a human life. Along with ‘bildning’ Snellman used also the terms ‘kultur’ and ‘civilisation’ when referring to the totality of a certain nation or historical era, including both the so-called high culture (arts, science, religion) and the modes of thought as well as ways of life of the people as a whole. Unlike many of his Finnish contemporaries, Snellman did not use civilisation as a negative concept, lacking the moral essence of German term ‘Bildung’ or ‘Kultur’. Instead, for Snellman civilisation was a neutral term and here he comes close to the French tradition of using the term. In the study I argue that Snellman’s conception of culture in fact includes a synthesis of the German tradition of ‘Bildung’ and the French tradition of ‘civilisation’.

Irtoamispäivän kurssilaskusuhteet, epänormaalit tuotot sekä epänormaalit kaupankäyntivolyymit vuosina 2005-2013

Tutkielman tavoitteena on tutkia osingon irtoamispäivän tapahtumia OMX Helsinki 25:n yrityksillä vuosina 2005–2013. Vallitsevan käsityksen mukaan osakkeen hinta laskee irtoamispäivänä osingon verran +/- markkinoiden yleisestä hintamuutoksesta johtuva nousu/lasku. Käsitystä on pyritty murtamaan vuosien saatossa neljän eri teorian avulla, jotka ovat veroasiakaskuntateoria, lyhytaikaisen vaihdon hypoteesi, dynaaminen malli sekä mikrorakenneteoria. Osingon irtoamispäivää tarkastellaan kolmen eri tutkimuksen avulla ja saatuja tuloksia verrataan teoriaan sekä aikaisempiin löydöksiin. Tutkimusosuudet ovat kurssilaskusuhteet, epänormaalit tuotot sekä epänormaalit kaupankäyntivolyymit. Kurssilaskusuhdetta tarkastellaan vertaamalla cum-päivän ja irtoamispäivän osakkeiden hintojen erotusta maksetun osingon määrään. Epänormaaleja tuottoja ja epänormaaleja kaupankäyntivolyymejä tarkastellaan tapahtumatutkimus-menetelmällä viisi päivää ennen ja viisi päivää jälkeen osingon irtoamisen. Kurssilaskusuhteet olivat eri tavoilla laskettuina 77 – 94 %. Irtoamispäivän ympärillä oli havaittavissa 1,5 %:n negatiivisia epänormaaleja tuottoja. Epänormaalit kaupankäyntivolyymit kasvoivat tasaisesti lähestyttäessä irtoamispäivää ja olivat voimakkaimmillaan irtoamispäivänä. Irtoamispäivän jälkeen kaupankäyntivolyymit palautuivat hiljalleen normaalille tasolle. Tulokset vastaavat aikaisempia löydöksiä kurssilaskusuhteita ja epänormaaleja volyymejä tarkasteltaessa, mutta eroavat epänormaaleissa tuotoissa.
