Aprenentatge esportiu: com influeix la conducta de l’entrenador en el procés d’aprenentatge de l’esportista

Les persones estem en constant desenvolupament i socialització, i cada context en el qual ens veiem involucrats té sobre nosaltres el poder de modificar les nostres conductes. El criteri de partida és que el context esportiu també exerceix aquest domini sobre els individus que hi participen, motiu pel qual en aquest treball es pretén estudiar la influència de certs factors en el desenvolupament de la pràctica esportiva. De manera més detallada, l’objectiu que es busca és estudiar la influència conductual de l’entrenador en el procés d’aprenentatge de l’esportista. A partir d’aquest estudi s’obtindrà un perfil de com ha de ser un bon entrenador i les condicions que s’han de donar en l’esportista perquè els aprenentatges esdevinguin significatius, la qual cosa portarà a la funcionalitat i la millora del rendiment esportiu.

The 21st century chemistry journal

Internet publication will radically alter how chemists will publish their research in the next century. In this article, we describe two fundamental changes: enhanced chemical publication which allows chemists to publish materials that cannot be published on paper and end-user customization which allows readers to read articles prepared to meet their specifications. These concepts have been implemented within the Internet Journal of Chemistry, a new journal designed to employ the latest technologies for chemical publications.

This article ties the expansion of the Mediterranean and Catalan prosperity to the growth, the changes and the maturing of the society in all aspects (politically, socially, culturally...) Two of the groups that illustrate the growth well and the changes that were taking place in Barcelona society are the craftsmen and craftswomen, liberal professionals and the merchants. The article relates the changes of the XIVth Century to the increase of the capacity to read and write of the men and women of these social groups. The books of accounts of two members of a Barcelona family of merchants and ships’s copyist of the XIVth Century, the Tarascó, are the testimony of the extension of “a functional” literacy, limited and closely together with the profession, work and religious practice. These and other private sources allow for the appreciation of the diffusion of writing. The people of the world of commerce and the sea are very conscious of the decisive value of writing not only for their professional activity, but also because it allows them to make note of, in order to be able, later on, to remember: desires, interests and preoccupations. The article, finally, offers a hypothesis of documentary genesis of books of mercantile accounts

Teaching mathematics and programming : new approaches with empirical evaluation

Programming and mathematics are core areas of computer science (CS) and consequently also important parts of CS education. Introductory instruction in these two topics is, however, not without problems. Studies show that CS students find programming difficult to learn and that teaching mathematical topics to CS novices is challenging. One reason for the latter is the disconnection between mathematics and programming found in many CS curricula, which results in students not seeing the relevance of the subject for their studies. In addition, reports indicate that students' mathematical capability and maturity levels are dropping. The challenges faced when teaching mathematics and programming at CS departments can also be traced back to gaps in students' prior education. In Finland the high school curriculum does not include CS as a subject; instead, focus is on learning to use the computer and its applications as tools. Similarly, many of the mathematics courses emphasize application of formulas, while logic, formalisms and proofs, which are important in CS, are avoided. Consequently, high school graduates are not well prepared for studies in CS. Motivated by these challenges, the goal of the present work is to describe new approaches to teaching mathematics and programming aimed at addressing these issues: Structured derivations is a logic-based approach to teaching mathematics, where formalisms and justifications are made explicit. The aim is to help students become better at communicating their reasoning using mathematical language and logical notation at the same time as they become more confident with formalisms. The Python programming language was originally designed with education in mind, and has a simple syntax compared to many other popular languages. The aim of using it in instruction is to address algorithms and their implementation in a way that allows focus to be put on learning algorithmic thinking and programming instead of on learning a complex syntax. Invariant based programming is a diagrammatic approach to developing programs that are correct by construction. The approach is based on elementary propositional and predicate logic, and makes explicit the underlying mathematical foundations of programming. The aim is also to show how mathematics in general, and logic in particular, can be used to create better programs.

Hållpunkter för lärande : småbarns möten

Developed from human activities, mathematical knowledge is bound to the world and cultures that men and women experience. One can say that mathematics is rooted in humans’ everyday life, an environment where people reach agreement regarding certain “laws” and principles in mathematics. Through interaction with worldly phenomena and people, children will always gain experience that they can then in turn use to understand future situations. Consequently, the environment in which a child grows up plays an important role in what that child experiences and what possibilities for learning that child has. Variation theory, a branch of phenomenographical research, defines human learning as changes in understanding and acting towards a specific phenomenon. Variation theory implies a focus on that which it is possible to learn in a specific learning situation, since only a limited number of critical aspects of a phenomenon can be simultaneously discerned and focused on. The aim of this study is to discern how toddlers experience and learn mathematics in a daycare environment. The study focuses on what toddlers experience, how their learning experience is formed, and how toddlers use their understanding to master their environment. Twenty-three children were observed videographically during everyday activities. The videographic methodology aims to describe and interpret human actions in natural settings. The children are aged from 1 year, 1 month to 3 years, 9 months. Descriptions of the toddlers’ actions and communication with other children and adults are analyzed phenomenographically in order to discover how the children come to understand the different aspects of mathematics they encounter. The study’s analysis reveals that toddlers encounter various mathematical concepts, similarities and differences, and the relationship between parts and whole. Children form their understanding of such aspects in interaction with other children and adults in their everyday life. The results also show that for a certain type of learning to occur, some critical conditions must exist. Variation, simultaneity, reasonableness and fixed points are critical conditions of learning that appear to be important for toddlers’ learning. These four critical conditions are integral parts of the learning process. How children understand mathematics influences how they use mathematics as a tool to master their surrounding world. The results of the study’s analysis of how children use their understanding of mathematics shows that children use mathematics to uphold societal rules, to describe their surrounding world, and as a tool for problem solving. Accordingly, mathematics can be considered a very important phenomenon that children should come into contact with in different ways and which needs to be recognized as a necessary part of children’s everyday life. Adults working with young children play an important role in setting perimeters for children’s experiences and possibilities to explore mathematical concepts and phenomena. Therefore, this study is significant as regards understanding how children learn mathematics through everyday activities.

Making Sense of Shared Leadership. A case study of leadership processes and practices without formal leadership structure in the team context

Leadership is essential for the effectiveness of the teams and organizations they are part of. The challenges facing organizations today require an exhaustive review of the strategic role of leadership. In this context, it is necessary to explore new types of leadership capable of providing an effective response to new needs. The presentday situations, characterized by complexity and ambiguity, make it difficult for an external leader to perform all leadership functions successfully. Likewise, knowledge-based work requires providing professional groups with sufficient autonomy to perform leadership functions. This study focuses on shared leadership in the team context. Shared leadership is seen as an emergent team property resulting from the distribution of leadership influence across multiple team members. Shared leadership entails sharing power and influence broadly among the team members rather than centralizing it in the hands of a single individual who acts in the clear role of a leader. By identifying the team itself as a key source of influence, this study points to the relational nature of leadership as a social construct where leadership is seen as social process of relating processes that are co-constructed by several team members. Based on recent theoretical developments concerned with relational, practice-based and constructionist approaches to the study of leadership processes, this thesis proposes the study of leadership interactions, working processes and practices to focus on the construction of direction, alignment and commitment. During the research process, critical events, activities, working processes and practices of a case team have been examined and analyzed with the grounded theory –approach in the terms of shared leadership. There are a variety of components to this complex process and a multitude of factors that may influence the development of shared leadership. The study suggests that the development process of shared leadership is a common sense -making process and consists of four overlapping dimensions (individual, social, structural, and developmental) to work with as a team. For shared leadership to emerge, the members of the team must offer leadership services, and the team as a whole must be willing to rely on leadership by multiple team members. For these individual and collective behaviors to occur, the team members must believe that offering influence to and accepting it from fellow team members are welcome and constructive actions. Leadership emerges when people with differing world views use dialogue and collaborative learning to create spaces where a shared common purpose can be achieved while a diversity of perspectives is preserved and valued. This study also suggests that this process can be supported by different kinds of meaning-making and process tools. Leadership, then, does not reside in a person or in a role, but in the social system. The built framework integrates the different dimensions of shared leadership and describes their relationships. This way, the findings of this study can be seen as a contribution to the understanding of what constitutes essential aspects of shared leadership in the team context that can be of theoretical value in terms of advancing the adoption and development process of shared leadership. In the real world, teams and organizations can create conditions to foster and facilitate the process. We should encourage leaders and team members to approach leadership as a collective effort that the team can be prepared for, so that the response is rapid and efficient.

Software for design of experiments and response modelling of cake ltration applications

Filtration is a widely used unit operation in chemical engineering. The huge variation in the properties of materials to be ltered makes the study of ltration a challenging task. One of the objectives of this thesis was to show that conventional ltration theories are di cult to use when the system to be modelled contains all of the stages and features that are present in a complete solid/liquid separation process. Furthermore, most of the ltration theories require experimental work to be performed in order to obtain critical parameters required by the theoretical models. Creating a good overall understanding of how the variables a ect the nal product in ltration is somewhat impossible on a purely theoretical basis. The complexity of solid/liquid separation processes require experimental work and when tests are needed, it is advisable to use experimental design techniques so that the goals can be achieved. The statistical design of experiments provides the necessary tools for recognising the e ects of variables. It also helps to perform experimental work more economically. Design of experiments is a prerequisite for creating empirical models that can describe how the measured response is related to the changes in the values of the variable. A software package was developed that provides a ltration practitioner with experimental designs and calculates the parameters for linear regression models, along with the graphical representation of the responses. The developed software consists of two software modules. These modules are LTDoE and LTRead. The LTDoE module is used to create experimental designs for di erent lter types. The lter types considered in the software are automatic vertical pressure lter, double-sided vertical pressure lter, horizontal membrane lter press, vacuum belt lter and ceramic capillary action disc lter. It is also possible to create experimental designs for those cases where the variables are totally user de ned, say for a customized ltration cycle or di erent piece of equipment. The LTRead-module is used to read the experimental data gathered from the experiments, to analyse the data and to create models for each of the measured responses. Introducing the structure of the software more in detail and showing some of the practical applications is the main part of this thesis. This approach to the study of cake ltration processes, as presented in this thesis, has been shown to have good practical value when making ltration tests.

Tiedon jakaminen virtuaalisissa IT-projekteissa

Sekä projektimainen että virtuaalinen työskentely ovat arkipäivää IT-alalla. Arkipäivää ovat myös uutiset epäonnistuneista tietojärjestelmäprojekteis-ta. Tehokas tiedon jakaminen on projektien menestystekijä. Tutkielmassa etsittiin vastausta kysymykseen: mitkä ovat tiedon jakamisen esteitä ja edistäjiä virtuaalisissa tietojärjestelmäprojekteissa. Tutkimusstrategia oli vertaileva tapaustutkimus. Aineisto kerättiin teema-haastatteluilla. Haastatteluun osallistui kymmenen henkilöä neljästä eri projektista. Henkilöt olivat eri organisaatioista ja edustivat niin asiakkaan, toimittajan kuin alihankkijoidenkin näkemyksiä. Eniten projekteissa jaet-tiin projektinhallintaan liittyvää tietoa, mutta ihmisten johtamiseen liittyvää tietoa ja liiketoimintahyötyihin liittyvää tietoa jaettiin vähän. Haastattelujen perusteella merkittävimmät tiedon jakamiseen vaikuttavat tekijät ovat yh-teisen käsitteistön ja yhteisen ymmärryksen puute, luottamus, tietotekni-set välineet sekä projektipäällikön toiminta. Yhteenvetona todetaan, että virtuaalisuus ei projekteissa aiheuttanut ongelmia, mutta se korosti muista syistä syntyneitä ongelmia. Virtuaalipro-jekteissa on erityistä huomiota kiinnitettävä projektin alkuvaiheessa ta-pahtuvaan tutustumiseen.

Työnantajan oikeus lukea työntekijän sähköposteja

Sähköpostin käyttö suomalaisilla työpaikoilla on kasvanut merkittävästi 2000 -luvun alusta lähtien. Tänä päivänä suuri osa työntekijöistä käyttää työpaikoillaan sähköpostia päivittäin. Tutkimuksen tavoitteena on tutkia työnantajan oikeutta lukea työntekijän sähköposteja. Edellisen lisäksi huomio kiinnittyi työntekijän yksityisyyden suojaan sekä työnantajan oikeuksiin ja velvollisuuksiin. Tutkimukseni on toteutettu kvalitatiivisena tutkimuksena. Tutkimusaineistoon valittiin kaikki tutkimusaihetta koskevat kirjoitukset. Aineisto kerättiin pääasiallisesti suomalaisista lakiteksteistä sekä tutkielmani empiirinen osio koostui neljästä suomalaisesta oikeustapauksesta. Tutkimuksen perusteella voidaan todeta, että Suomessa työnantajat osaavat kunnioittaa työntekijän yksityisyyttä ja sähköpostin käytöstä työpaikoilla ei ole usein syntynyt ongelmia.

Taloushallinnon raportoinnin kehittäminen - case Trust Accounts

Taloushallinnon raportoinnilla on merkittävä tehtävä yritysten liiketoiminnan johtamisessa. Se antaa tietoa paitsi yrityksen menneisyydestä ja tämän hetkisestä tilanteesta, sen avulla on myös mahdollista ennustaa tulevaisuutta. Taloushallinnon tiedolla on tärkeä rooli, koska sitä hyödynnetään esimerkiksi päätöksenteon tukena. Raporttien sisältämä tieto on oltava paitsi oikeaa ja yritykselle tärkeää, sen on oltava myös helposti luettavissa ja ymmärrettävissä. Raporttien luettavuutta ja lukijoiden raporttien lukutaitoa parantamalla on mahdollista saada yritykset hyödyntämään raportteja entistä enemmän. Jos yritykset eivät osaa lukea raportteja, eivät he niitä tule myöskään hyödyntämään liiketoimintansa johtamisessa. Tämän pro gradu -tutkielman tavoitteena oli antaa toimeksiantajayritykselle kehitysideoita asiakasyrityksiltä siitä, kuinka he voisivat parantaa taloushallinnon raportointia. Tutkimus on toteutettu laadullisena, eli kvalitatiivisena tutkimuksena. Tutkimusmenetelmänä on käytetty haastattelua, joka sisältää piirteitä sekä strukturoidusta että puolistrukturoidusta haastattelusta. Tutkimuksen tuloksena toimeksiantajayritykselle on koottu taulukkoon (1) asiakasyritysten haastatteluista saadut kehitysideat. Kehitysideoiden avulla toimeksiantajayritys voi kehittää omia raportointivälineitään ja sitä kautta lisätä asiakastyytyväisyyttä heidän tilitoimistoa kohtaan
