Protocolo para la evaluación del Trabajo Fin de Grado de Trabajo Social

Se presenta el protocolo a seguir para una correcta evaluación del Trabajo Fin de Grado (TFG). Este diseño aglutina el análisis y reflexión de la experiencia realizada en este tema por diferentes universidades internacionales y nacionales en distintos foros y jornadas científicas de innovación docente. Se busca establecer una serie de pasos a seguir por los estudiantes que favorezcan su total autonomía en la realización, seguimiento y evaluación. Este proceso se establece a través de la total participación activa de los estudiantes. Los estudiantes tienen que ser autónomos en la realización de su trabajo y desafortunadamente tienen la dificultad de no contar con estructuras o procesos ordenados que les guíen en ello. Estas circunstancias nos han llevado a la configuración de un protocolo o proceso estructurado de pautas que los estudiantes deben cumplir de forma rigurosa. Este protocolo permite la redacción y adecuada elaboración de un trabajo académico, mediante la utilización de los requisitos establecidos y el respeto a los controles de calidad fijados previamente. Por último, se ha revisado la literatura científica sobre protocolos de evaluación utilizados de TFGs en diferentes universidades del área social y jurídica.

La implicación del docente en el trabajo fin de grado: responsabilidades y reconocimiento académico

El presente trabajo analiza el Trabajo Fin de Grado como asignatura obligatoria del último curso del Grado. Lo hace desde la perspectiva descriptiva y crítica pero centrada en la experiencia de la Facultad de Derecho de la Universidad Complutense de Madrid y más en concreto del Departamento de Derecho constitucional, ya que cada experiencia es única. De los muchos aspectos susceptibles de análisis se incide de manera especial en las responsabilidades del Tutor/docente de esta asignatura TFG y en el reconocimiento académico que otorga la Universidad a los profesores de la misma. Se utilizan como experiencias alternativas otras Facultades y se proponen sugerencias de cambio o mejora en el diseño del TFG.

La influencia de John Henry Newman en la reflexión educativa del último medio siglo

La influencia de John Henry Newman en la reflexión educativa del último medio siglo pretende demostrar que el núcleo de la teoría educativa newmaniana constituye el referente a partir del cual es posible comprender la forma en que lo educativo está siendo pensado en la actualidad, en un contexto preferentemente cristiano. Para ello, esta investigación proporciona una línea interpretativa que se aleja de la tradición hermenéutica que se ha seguido en la filosofía educativa newmaniana. En lugar de leer esta intentando explicar los discursos en relación a la biografía de Newman, o en contraste con la suerte de su institución, o los textos en sí mismos, sitúa los argumentos educativos en relación con los de otras obras del opus newmaniano. Este modo de proceder permite trazar la influencia de John Henry Newman en la reflexión educativa actual, que se concreta en tres autores: Joseph Ratzinger, Alasdair MacIntyre y Bernard Lonergan. Lo que une a este grupo de intelectuales tan heterogéneo es que reconocieron públicamente una deuda intelectual con Newman, que este condicionó algunos aspectos de su pensamiento y que desarrollaron un conjunto de reflexiones relevantes para la educación en las que Newman terminaba apareciendo, indefectiblemente. No obstante, para conocer esto último con precisión, y dado que a estos autores también les une el hecho de que escribieron sobre educación sólo accidentalmente, esta investigación ofrece una reconstrucción orgánica del pensamiento educativo de cada uno de ellos a la luz de los elementos principales de sus pensamientos. De esta manera, vistas sus reflexiones educativas desde una perspectiva sistemática, es posible conocer los argumentos concretos en que Newman está pretense y, por lo tanto, calibrar la intensidad de su influencia. Esta última se podría medir, así, en dos dimensiones. Una primera, en la que se vería que los elementos de los discursos de Dublín que los autores han tomado para componer sus reflexiones sobre la educación, de forma unánime, son la apología de la teología y el fin de la universidad como la formación de un hábito filosófico de la mente. Pero, además, dado que se adopta una opción hermenéutica distinta a la tradicional, en la que, como dije, se lee la Idea en relación a las obras completas del cardenal, se podría deducir un conjunto de influencias más amplio...

Analysis of heat transfer and fluid flow in a triangular enclosure in presence of an adiabatic fin

Natural convection thermal boundary layer adjacent to the heated inclined wall of a right angled triangle with an adiabatic fin attached to that surface is investigated by numerical simulations. The finite volume based unsteady numerical model is adopted for the simulation. It is revealed from the numerical results that the development of the boundary layer along the inclined surface is characterized by three distinct stages, i.e. a start-up stage, a transitional stage and a steady stage. These three stages can be clearly identified from the numerical simulations. Moreover, in presence of adiabatic fin, the thermal boundary layer adjacent to the inclined wall breaks initially. However, it is reattached with the downstream boundary layer next to the fin. More attention has been given to the boundary layer development near the fin area.

Constrained predictive control of ship fin stabilizers to prevent dynamic stall

In moderate to high sea states, the effectiveness of ship fin stabilizers can severely deteriorate due to nonlinear effects arising from unsteady hydrodynamic characteristics of the fins: dynamic stall. These nonlinear effects take the form of a hysteresis, and they become very significant when the effective angle of attack of the fins exceeds a certain threshold angle. Dynamic stall can result in a complete loss of control action depending on how much the fins exceed the threshold angle. When this is detected, it is common to reduce the gain of the controller that commands the fins. This approach is cautious and tends to reduce performance when the conditions leading to dynamic stall disappear. An alternative approach for preventing the effects while keeping high performance, consists of estimating the effective angle of attack and set a conservative constraint on it as part of the control objectives. In this paper, we investigate the latter approach, and propose the use of a model predictive control (MPC) to prevent the development of these nonlinear effects by considering constraints on both the mechanical angle of the fins and the effective angle of attack.

Transition to an unsteady flow induced by a fin on the sidewall of a differentially heated air-filled square cavity and heat transfer

The transition from a steady to an unsteady flow induced by an adiabatic fin on the sidewall of a differentially heated air-filled cavity is numerically investigated. Numerical simulations have been performed over the range of Rayleigh numbers from Ra = 105–109. The temporal development and spatial structures of natural convection flows in the cavity with a fin are described. It has been demonstrated that the fin may induce the transition to an unsteady flow and the critical Rayleigh number for the occurrence of the transition is between 3.72 × 106 and 3.73 × 106. Furthermore, the peak frequencies of the oscillations triggered by different mechanisms are obtained through spectral analysis. It has been found that the flow rate through the cavity with a fin is larger than that without a fin under the unsteady flow, indicating that the fin may improve the unsteady flow in the cavity.

Does size matter? An assessment of quota market evolution and performance in the Great Barrier Reef fin-fish fishery

In fisheries managed using individual transferable quotas (ITQs) it is generally assumed that quota markets are well-functioning, allowing quota to flow on either a temporary or permanent basis to those able to make best use of it. However, despite an increasing number of fisheries being managed under ITQs, empirical assessments of the quota markets that have actually evolved in these fisheries remain scarce. The Queensland Coral Reef Fin-Fish Fishery (CRFFF) on the Great Barrier Reef has been managed under a system of ITQs since 2004. Data on individual quota holdings and trades for the period 2004-2012 were used to assess the CRFFF quota market and its evolution through time. Network analysis was applied to assess market structure and the nature of lease-trading relationships. An assessment of market participants’ abilities to balance their quota accounts, i.e., gap analysis, provided insights into market functionality and how this may have changed in the period observed. Trends in ownership and trade were determined, and market participants were identified as belonging to one out of a set of seven generalized types. The emergence of groups such as investors and lease-dependent fishers is clear. In 2011-2012, 41% of coral trout quota was owned by participants that did not fish it, and 64% of total coral trout landings were made by fishers that owned only 10% of the quota. Quota brokers emerged whose influence on the market varied with the bioeconomic conditions of the fishery. Throughout the study period some quota was found to remain inactive, implying potential market inefficiencies. Contribution to this inactivity appeared asymmetrical, with most residing in the hands of smaller quota holders. The importance of transaction costs in the operation of the quota market and the inequalities that may result are discussed in light of these findings

Micro-economic drivers of profitability in an ITQ-managed fishery: An analysis of the Queensland Coral Reef Fin-Fish Fishery

An economic survey of the commercial operators currently active in the Queensland Coral Reef Fin-Fish Fishery has been carried out, as part of a research project aimed at evaluating alternative management options for this fishery. This paper presents the background analysis used as a basis to develop the sampling design for this survey. The background analysis focuses on activity patterns of the fleet based on effort and catch information, as well as patterns of quota ownership. Based on this information, a fishing business profile describing the micro-economic structure of fishing operations is developed. This profile, in conjunction with the qualitative information gained in undertaking the economic surveys, allows preliminary understanding of the key drivers of profitability in the CRFFF, and possible impacts of external factors on fishing operations.

Numerical Study of Heat Transfer From Pin-Fin Heat Sink Using Steady and Pulsated Impinging Jets

This paper investigates numerically the heat transfer characteristics of confined slot jet impingement on a pin-fin heat sink. A variety of pin-fin heat sinks is investigated, and the resulting enhancement of heat transfer studied. The distribution of heat transfer coefficient on the top surface of the base plate and that along the fin height are examined. Both steady and pulsated jets are studied. It is observed that for a steady jet impingement on a pin-fin heat sink, the effective heat transfer coefficient increases with fin height, leading to a corresponding decrease in base plate temperature for the same heat flux. In the case of pulsated jets, the influence of pulse frequency and the Reynolds number is examined, and their effect on the effective heat transfer coefficient is studied.

Experimental Demonstration of H{infty} Control based Active Vibration Suppression in Composite Fin-tip of Aircraft using Optimally Placed Piezoelectric Patch Actuators

The goal of this study is the multi-mode structural vibration control in the composite fin-tip of an aircraft. Structural model of the composite fin-tip with surface bonded piezoelectric actuators is developed using the finite element method. The finite element model is updated experimentally to reflect the natural frequencies and mode shapes accurately. A model order reduction technique is employed for reducing the finite element structural matrices before developing the controller. Particle swarm based evolutionary optimization technique is used for optimal placement of piezoelectric patch actuators and accelerometer sensors to suppress vibration. H{infty} based active vibration controllers are designed directly in the discrete domain and implemented using dSpace® (DS-1005) electronic signal processing boards. Significant vibration suppression in the multiple bending modes of interest is experimentally demonstrated for sinusoidal and band limited white noise forcing functions.

Fin de millénaire eli maailmanlopun satiiri : Frédéric Beigbederin Au secours pardon, Marie Darrieussecqin Truismes ja Michel Houellebecqin La Possibilité d'une île

Pro gradu -työni käsittelee ranskalaisen nykykirjallisuuden yhteiskunnallista suuntausta, jota kirjallisuudentutkija Ruth Cruickshank kutsuu fin de millénaire -kirjallisuudeksi. Tutkimani teokset ovat Frédéric Beigbederin Au secours pardon (2007), Marie Darrieussecqin Truismes (1996) ja Michel Houellebecqin La Possibilité d'une île (2005). Pohdin, millaisena ja millaisin keinoin teokset kuvaavat seksuaalisuutta ja sen tulevaisuudennäkymiä kulutusyhteiskunnassa, ja millaisiin yhteiskunnallisiin olosuhteisiin niiden havainnot perustuvat. Hahmottelen reittejä, joita pitkin globaalin mittakaavan yhteiskunnalliset muutokset vaikuttavat ihmisten intiimeihin tunteisiin ja ihmissuhteisiin. Seksuaalisuuden tarkastelun avulla osoitan, että ranskalaisessa nykykirjallisuudessa ilmenee varsin yhteneviä näkemyksiä ja uhkakuvia aikamme sosiaalisesta todellisuudesta. Tällä tavoin tarkennan ja vankennan vielä hajanaista fin de millénaire -käsitettä. Fin de millénaire -kirjallisuuden oma lajityyppi on massakulttuurin, esimerkiksi viihteen ja mainosten, kielestä vaikutteita ammentava dystopian ja satiirin liitto. Kuten Cruickshank kirjoittaa, fin de millénaire -kirjallisuus heijastaa Ranskassa vuosituhannen vaihteessa korostunutta tunnetta käännekohtaan saapumisesta. Dystopian ohella voidaankin puhua myös apokalyptisesta tekstistä, etenkin siksi, että teokset tarjoavat niukasti ratkaisuja kuvaamiinsa ongelmiin. Eritoten Houellebecqin ja Beigbederin teokset käsittelevät tarpeiden luomista kuluttajille seksuaalivietin ja seksuaalisen kilpailun avulla. Kutsun tätä järjestelmää halutaloudeksi, ja käytän sen toiminnan analysoimisessa apuna Michel Foucault'n käsityksiä vallasta ja Jean Baudrillardin käsityksiä kulutusyhteiskunnasta. Halutalouden sosiaalisia seurauksia ovat vieraantuminen, seksuaalisten hierarkioiden jyrkentyminen ja valinnanvapauden kaventuminen. Teosten kuvaamassa yhteiskunnassa erilaiset esimerkiksi sukupuolen, iän ja ulkonäön perusteella rakentuvat seksuaaliset hierarkiat käyvät yhä merkittävämmiksi. Au secours pardon ja La Possibilité d'une île kuvaavat tapahtumaketjua, jossa etenkin heteromiehistä yhä useampi luisuu seksuaaliseen kurjuuteen muun muassa naisten emansipaation sekä yleisen nuoruuden ja kauneuden palvonnan myötä. Truismesissa taas kuvitellaan yhteiskunta, johon feminismi ei ole päässyt vaikuttamaan mutta pornoistuminen on; naisten ruumiista on tullut miesten yhteistä omaisuutta ja seksuaalinen väkivalta on arkipäivää. Sen maailmassa viehättävä ulkonäkö on naisille miltei elinehto. Yleistäen Houellebecqin ja Beigbederin teokset edustavat miesnäkökulmaa ja Darrieussecqin teos naisnäkökulmaa. Teosten näkemyksiä naisten ja miesten välisistä valtasuhteista pohdin naisten seksuaalisesta vallasta kirjoittaneen Henry Laasasen käyttökelpoisten käsitteiden avulla. Kolmea teosta yhdistävät kuvaukset kulttuurista, jossa ihmissuhteet ovat kaupankäyntiä ja seksuaalinen viehätysvoima määrittelee ihmisen arvon. Darrieussecqin teos on lähitulevaisuuteen sijoittuva dystopia, jossa Beigbederin ja Houellebecqin kuvaama arvoliberalismia ja taloudellista liberalismia yhdistävä kulttuuri on vaihtunut uuskonservatiiviseen ja kaksinaismoralistiseen, naisia räikeästi sortavaan yhteiskuntaan. Teoksen kertoja vähättelee itseensä kohdistuvia koskemattomuuden loukkauksia ja pahoittelee kertomuksensa käänteiden säädyttömyyttä varsinkin kuvatessaan omaa haluaan ja seksuaalista subjektiuttaan. Katson teoksen kritisoivan kirjallisuudentutkija Shirley Ann Jordanin termein poliittisen korrektiuden tyranniaa ja peräänkuuluttavan suoraa puhetta pornografiasta ja naisen halusta. Seksuaalisuus toimii tutkimuksessani lähtökohtana, jonka avulla teoksista nousee esiin julma ja rakkaudeton, säälimättömän kilpailun ja väkivallan täyttämä yhteiskunta. Viime kädessä teosten kuvaama maailmanloppu on se, että rakkaus katoaa ihmisten välisistä suhteista, koska rakkaudessa ei ole voiton tavoittelun kannalta mitään järkeä. Satiirin keinojen, kuten päättymättömän ja monikerroksisen ironian, yhdistyminen dystopiaan pelastaa teokset osoittelevalta moralisoinnilta ja tekee niistä toimivaa yhteiskunnallista kirjallisuutta.

FIN-CLARIN: A Framework for Depositing and Disseminating Language Resources for R&D

Researchers and developers in academia and industry would benefit from a facility that enables them to easily locate, licence and use the kind of empirical data they need for testing and refining their hypotheses and to deposit and disseminate their data e.g. to support replication and validation of reported scientific experiments. To answer these needs initially in Finland, there is an ongoing project at University of Helsinki and its collaborators to create a user-friendly web service for researchers and developers in Finland and other countries. In our talk, we describe ongoing work to create a palette of extensive but easily available Finnish language resources and technologies for the research community, including lexical resources, wordnets, morphologically tagged corpora, dependency syntactic treebanks and parsebanks, open-source finite state toolkits and libraries and language models to support text analysis and processing at customer site. Also first publicly available results are presented.

Numerical Study Of Heat Transfer From Pin Fin Heat Sink Using Steady And Pulsated Impinging Jets

The work reported in this thesis is an attempt to enhance heat transfer in electronic devices with the use of impinging air jets on pin-finned heat sinks. The cooling per-formance of electronic devices has attracted increased attention owing to the demand of compact size, higher power densities and demands on system performance and re-liability. Although the technology of cooling has greatly advanced, the main cause of malfunction of the electronic devices remains overheating. The problem arises due to restriction of space and also due to high heat dissipation rates, which have increased from a fraction of a W/cm2to 100s of W /cm2. Although several researchers have at-tempted to address this at the design stage, unfortunately the speed of invention of cooling mechanism has not kept pace with the ever-increasing requirement of heat re- moval from electronic chips. As a result, efficient cooling of electronic chip remains a challenge in thermal engineering. Heat transfer can be enhanced by several ways like air cooling, liquid cooling, phase change cooling etc. However, in certain applications due to limitations on cost and weight, eg. air borne application, air cooling is imperative. The heat transfer can be increased by two ways. First, increasing the heat transfer coefficient (forced convec- tion), and second, increasing the surface area of heat transfer (finned heat sinks). From previous literature it was established that for a given volumetric air flow rate, jet im-pingement is the best option for enhancing heat transfer coefficient and for a given volume of heat sink material pin-finned heat sinks are the best option because of their high surface area to volume ratio. There are certain applications where very high jet velocities cannot be used because of limitations of noise and presence of delicate components. This process can further be improved by pulsating the jet. A steady jet often stabilizes the boundary layer on the surface to be cooled. Enhancement in the convective heat transfer can be achieved if the boundary layer is broken. Disruptions in the boundary layer can be caused by pulsating the impinging jet, i.e., making the jet unsteady. Besides, the pulsations lead to chaotic mixing, i.e., the fluid particles no more follow well defined streamlines but move unpredictably through the stagnation region. Thus the flow mimics turbulence at low Reynolds number. The pulsation should be done in such a way that the boundary layer can be disturbed periodically and yet adequate coolant is made available. So, that there is not much variation in temperature during one pulse cycle. From previous literature it was found that square waveform is most effective in enhancing heat transfer. In the present study the combined effect of pin-finned heat sink and impinging slot jet, both steady and unsteady, has been investigated for both laminar and turbulent flows. The effect of fin height and height of impingement has been studied. The jets have been pulsated in square waveform to study the effect of frequency and duty cycle. This thesis attempts to increase our understanding of the slot jet impingement on pin-finned heat sinks through numerical investigations. A systematic study is carried out using the finite-volume code FLUENT (Version 6.2) to solve the thermal and flow fields. The standard k-ε model for turbulence equations and two layer zonal model in wall function are used in the problem Pressure-velocity coupling is handled using the SIMPLE algorithm with a staggered grid. The parameters that affect the heat transfer coefficient are: height of the fins, total height of impingement, jet exit Reynolds number, frequency of the jet and duty cycle (percentage time the jet is flowing during one complete cycle of the pulse). From the studies carried out it was found that: a) beyond a certain height of the fin the rate of enhancement of heat transfer becomes very low with further increase in height, b) the heat transfer enhancement is much more sensitive to any changes at low Reynolds number than compared to high Reynolds number, c) for a given total height of impingement the use of fins and pulsated jet, increases the effective heat transfer coefficient by almost 200% for the same average Reynolds number, d) for all the cases it was observed that the optimum frequency of impingement is around 50 − 100 Hz and optimum duty cycle around 25-33.33%, e) in the case of turbulent jets the enhancement in heat transfer due to pulsations is very less compared to the enhancement in case of laminar jets.
