Skill Acquisition and the Influence of Attentional Focus and Practice

Attentional focus and practice schedules are important components in learning a new skill. For attention this includes focusing inward or outward, for practice this includes interference between tasks. Little is known about how the two interact. Four groups; blocked/extraneous (BE); blocked/skill-focused (BS); random/extraneous (RE); and random/skill-focused (RS), practiced 100 trials of golf putting and 64 trials of a key-pressing task in addition to responding to a random tone distracting attention towards or away from skill movement. Participants performed immediate and delayed retention tests. Results demonstrated the BE group had decreased RTE scores compared to the BS group. Immediate retention demonstrated superior scores for blocked practice. Delayed retention demonstrated superior CEVE scores for extraneous focus. For golf putting, both attention conditions with blocked practice learned faster compared to random groups. Posttest scores demonstrated the random and skill focused group to improve in all putting conditions.

Learning -dependent plasticity of movement representations in the primate primary motor cortex

Primary motor cortex (M1) is involved in the production of voluntary movement and contains a complete functional representation, or map, of the skeletal musculature. This functional map can be altered by pathological experiences, such as peripheral nerve injury or stroke, by pharmacological manipulation, and by behavioral experience. The process by which experience-dependent alterations of cortical function occur is termed plasticity. In this thesis, plasticity of M1 functional organization as a consequence of behavioral experience was examined in adult primates (squirrel monkeys). Maps of movement representations were derived under anesthesia using intracortical microstimulation, whereby a microelectrode was inserted into the cortex to electrically stimulate corticospinal neurons at low current levels and evoke movements of the forelimb, principally of the hand. Movement representations were examined before and at several times after training on behavioral tasks that emphasized use of the fingers. Two behavioral tasks were utilized that dissociated the repetition of motor activity from the acquisition of motor skills. One task was easy to perform, and as such promoted repetitive motor activity without learning. The other task was more difficult, requiring the acquisition of motor skills for successful performance. Kinematic analysis indicated that monkeys used a consistent set of forelimb movements during pellet extractions. Functional mapping revealed that repetitive motor activity during the easier task did not produce plastic changes in movement representations. Instead, map plasticity, in the form of selective expansions of task-related movement representations, was only produced following skill acquisition on the difficult task. Additional studies revealed that, in general, map plasticity persisted without further training for up to three months, in parallel with the retention of task-related motor skills. Also, extensive additional training on the small well task produced further improvements in performance, and further changes in movement maps. In sum, these experiments support the following three conclusions regarding the role of M1 in motor learning. First, behaviorally-driven plasticity is learning-dependent, not activity-dependent. Second, plastic changes in M1 functional representations represent a neural correlate of acquired motor skills. Third, the persistence of map plasticity suggests that M1 is part of the neural substrate for the memory of motor skills. ^

Jerónimo Sánchez Carranza y la Escuela Española de Esgrima

El deporte de la esgrima no siempre ha sido considerado como actualmente se conoce, ni tampoco el empleo de las armas ha sido el mismo en las diferentes épocas de la historia. Si nos centramos en la española, podemos decir que se hablaba de una forma particular de hacer esgrima, la cual era muy apreciada por el resto de los países europeos. También lo era la que se hacía en Italia. Como cualquier actividad que se desarrolla a lo largo del tiempo debe generarse desde unos comienzos. Estos comienzos siempre están en relación a alguna causa. Para centrarnos en nuestro estudio, los comienzos del manejo de la espada, de una manera lógica y razonada, se une en la persona y en la vida de Jerónimo Sánchez Carranza porque hasta que él no se decide a estudiar en profundidad la ciencia de las armas, no se ve con claridad si todo lo que se hacía con ellas era correcto o no y si todo lo que la inmensa mayoría hacía cuando tenía que utilizarlas estaba revestido de cierta coherencia y fundamento, es decir, tenía su verdad que se pudiera demostrar. Carranza estudia la esgrima que se empleaba en su época y en las anteriores y se da cuenta que tiene que dar una nueva visión de la forma de usar las armas, diferente a lo que la gran mayoría entendía hasta entonces. A Carranza se le ha considerado por muchos autores como el inventor de la esgrima española, hecho que se puede leer con bastante facilidad si se hojea algún tratado que hable de la esgrima española, sin embargo también se habla de Luis Pacheco de Narváez asignándole el mismo calificativo, aunn- ;o es posteriora Carranza. or tanto nuestro estudio se ha centrado en la vida de Jerónimo Sánchez Carranza y en ueva forma de emplear las armas por lo que hace que la tesis sea una tesis biográfica de dicho personaje, donde se ha resaltado mucho más el aspecto del manejo de las armas, de la Destreza. Partimos de las siguientes hipótesis: Carranza es el que sienta los principios técnicos dando forma y coherencia a la escuela de esgrima española gracias a sus aportaciones en los distintos aspectos metodológicos, técnicos y tácticos. La escuela de esgrima española tiene una estructura interna, responde a unas características determinadas y sirve de base a la esgrima que posteriormente se practica. Para que el estudio se pudiera llevar a cabo tuvimos que diseñar un esquema donde se pudieran recoger todos los aspectos que estuvieran relacionados con nuestro autor, de ahí surge el porqué de cada uno de los capítulos que hemos confeccionado. Dicho esquema responde a la visión actual de diferentes facetas de lo que hoy se estudia en diversas ciencias y que cuando Carranza vivía aún no se conocían. Para recoger información sobre su persona y su obra tuvimos en cuenta los distintos lugares donde se podía localizar la documentación necesaria, sobre todo Bibliotecas y Archivos, para ir confeccionando el método de trabajo que consistió en la recopilación de fuentes de todo tipo referidas al tema, pasando luego a la interpretación de las mismas. Esto nos dio una visión de conjunto que hizo que nos adentráramos en aquellos aspectos que más tarde tendríamos que analizar con mucho más detenimiento. En la tesis se puede observar dos partes bien diferenciadas que son las relacionadas; por un lado, a su vida y su tratado y, por otro, al contenido de sus teorías que son realmente las que se deben analizar necesariamente bajo unos conocimientos específicos de la actividad de la esgrima. En cuanto a su vida, se han destacado y estudiado los hechos más importantes de los que hay que resaltar, sobre todo, el que fuera considerado como el inventor de la destreza y de la manera tan particular de concebir dicho arte, diferente a lo que hasta ahora se venía haciendo y que dio paso a lo que se entendió por esgrima científica, quedando plasmada de tal manera que dio pie a la creación de una doctrina y una nueva forma de entender la esgrima la cual generó una línea de actuación que fue continuada por numerosos seguidores. Para todo ello tuvo mucho que ver el que Carranza fuera militar, la cultura y los estudios que poseía, así como la situación en la que se encontraba España además de la gente con quien se relacionaba, que por lo general, era gente culta y de clase social alta. Se ha estudiado también dentro del mismo apartado de su vida unos hechos que se le imputan y que en nuestra opinión son erróneos. Hemos considerado como más relevantes el que Carranza no fue quien riñó con Quevedo como se afirma en algunas de las obras que hemos tratado, sino que fue Pacheco quien tuvo dicha riña, ya que más bien Quevedo se mostraba partidario de las enseñanzas de Carranza, estando en contra de Pacheco. Tampoco fue quien inventó el florete como se dice en algunas ocasiones, ya que el florete aparece posteriormente como un arma de estudio de la técnica de la esgrima. Con respecto al apartado de su obra, se debe decir que tan solo escribió un único tratado que se publicó en 1582, aunque estaba acabado desde el año 1569. En el apartado de su escuela se debe destacar los fundamentos en los que basó sus postulados para que la destreza alcanzara el mismo nivel de las demás artes liberales y que lo hizo a través del estudio de la propia destreza. A lo largo del estudio que hemos realizado se puede apreciar cómo se está generando un arte que hasta ahora no había sido estudiado, viéndose los problemas que ello suponía, desde la organización de la materia a tratar, hasta cómo se debía enseñar, pasando a veces a tener que denominar conceptos de nueva aparición o renombrar y modificar antiguos que estaban anclados en puntos de partida equivocados, siendo éstos los que mayor trabajo le supuso. Diferencia bien dos aspectos básicos que debían existir en cualquier arte y más concretamente en la destreza que son: la teoría y la práctica, ambas deben estar en base a la razón ya que sería una de las formas por la que la destreza perduraría en el tiempo, junto con que esta razón estuviera apoyada en otras ciencias y con los principios de ellas. Carranza fue de la opinión de que el diestro debía conocer mediante el estudio, los elementos fundamentales con los que había que trabajar la destreza, estos elementos son el cuerpo del diestro y las armas, porque ambos van a intervenir en cualquier gesto o acción que se vaya a realizar. Del cuerpo estudió cada una de las partes que más importancia tiene cada vez que el diestro interviene y lo hace sobre todo en base a la medicina, relacionándolo con las matemáticas para poder sacar el máximo provecho, aconsejando que por el conocimiento del propio cuerpo, como el del contrario, se podrá emplear en determinadas situaciones, que si no se supiera de ello, no se sacaría el mismo resultado. De las armas lo que más resaltó fue, por un lado, que la espada debía ser el único arma que el diestro debía utilizar y, por otro, el hecho de que la espada la graduara para poder demostrar que no se hacia todo igual con las distintas partes de la misma porque no todo el arma tenía las mismas propiedades cuando se actuaba con ella. Una de las recomendaciones que dio fue que con la parte más próxima a la empuñadura se debía practicar la defensa por tener más fuerza con esta parte que con la punta y lo demostró con principios matemáticos. Se puede ver con la lectura de la tesis cómo Carranza aporta una nueva forma de trabajo en la que le da mucha importancia a la aplicación de los conocimientos, que previamente se han adquirido y para ello, es importante conocer bien los puntos fuertes y débiles del adversario. La adquisición de la práctica se debe realizar a través de la repetición para crear el hábito necesario que haga que el gesto salga fluido en cada uno de los movimientos que el diestro ejecute. Todo esto no sería posible si quien lo enseña no conoce cada uno de los elementos que intervienen en la destreza, por tanto, a la figura del maestro le da un lugar de una gran relevancia, ya que va a ser él quien tenga que guiar a los alumnos que enseñe. Lo primero que debe hacer los maestros es procurar saber lo máximo de la materia que va a enseñar, por lo que el maestro debe saber casi todo sobre la teoría y la práctica de la destreza, pero además esta teoría y práctica debe ser la correcta. Carranza persigue con su estudio, establecer los principios de la destreza, por lo menos, los más importantes, aunque fueran elementales, para que posteriormente se siguiera trabajando sobre ellos y poder conseguir que la destreza tenga cuerpo y forma de arte liberal, pudiéndose estudiar como cualquier otra, así de esta manera se haría un bien público, ya que los jóvenes se instruirían eficazmente en el uso de las armas, aunque el verdadero fin se encuentra en la conservación de la vida como manda la Fe Católica, siendo la destreza uno de los medios más eficaces para conseguirlo. Hemos dedicado un apartado de técnica y de táctica donde se refleja todo lo relacionado con las posiciones y movimientos que debe realizar el diestro para llegar a conseguir su objetivo, que es herir sin ser herido. Se han analizado las distintas tretas y el porqué de cada una desde el punto de vista del gesto y del movimiento. Si lo que se hace en destreza se relaciona con el adversario, nos adentramos en el terreno de la táctica donde se han estudiado como más importantes los conceptos del tiempo y la distancia, así como las energías que debe conservar el diestro para poder llevar a cabo un combate y del mismo salir victorioso sin llegar al agotamiento. Concluimos diciendo que de todo el estudio que se ha realizado, se ha podido comprobar que Carranza fue quien dotó a la destreza de unos principios técnicos, tácticos y metodológicos, por su forma de concebir este nuevo arte, así como que por la manera en que estableció sus teorías hizo que la destreza que se practicaba en España disfrutara de una estructura interna coherente que perduró a través de los años. SUMMARY The sport of fencing has not always been the respected sport that we know it to be today ñor has the use of weapons been the same throughout history. If we concéntrate on Spainish weapons, we can say that one particular type of sword ¡s spoken about. this sword being very respected by outher European countries, it was also the one that was respected and used in Italy. As with any activity that develops in time, it must evlove from some simple beginnings. Such basics beginnings are always in relation to a cause. To concéntrate on our study, the beginnings are, the use of the sword in a reasoned and logical manner, brought together in the life and times of Jerónimo Sánchez Carranza because until he decided to study in depth the science of weapons, we cannot see with calrity if their use was correct or not and if the vast majority , when they had to use them, used any foundation or coherence, that ¡s to say if any exactness of logical use could be demonstrated. Carranza studied the sword used in his time and those that had gone before, bearing in mind that he had a new visión of the form of use of weapons, different to what the vast majority had until then understood. Carranza has been considered by many historians as the inventor of the Spanish sword, a fact which can be seen with relative ease if one flicks through any work which deals with the Spanish sword, however, they also speak of Luis Pacheco de Narváez affording him the same title, even though he followed Carranza. In ar H our study has been centred on the life of Jerónimo Sánchez Carranza and his ne-" use of weapons. In effect this thesis is a biographical thesis of the said wherein the aspect of the use of weapons stands out more than their mastery. Given the following hypothesis: It was Carranza who evolved the first techniques giving form and coherence to the .Spanish School of Fencing, thanks to his contributions to the different aspects of method, íechnique and tactic. The Spanish School of Fencing had an ¡nternal structure anaswerable to pre-detremined characteristics and served as a base for the fencing that was to, in later days, be practised. For this study to come to a head, we had to design a plan wherein we could collate all of the aspects we could, related to our inventor. From there springs the reason for each of the chapters that we have put together. The said plan responding to the actual visión of different facets that are studied today in different sciences, that were not known in Carranza's lifetime. To collect information on his person and his works we bore in mind the different places in which we could lócate the necessary documentation, above all in libraries and archives. Developing the work-method that consisted in extracing from every source, every thing relative to the theme, re-writing later our interpretation of the same. This brought us closer and made us focus of those aspects that much later we would have to analize in greater detail. In the thesis one can observe two defferent parts that are related; on the one hand his life and works and on the other his theories, which are those that should be really analised and as such, necessarily analised within the confines of a specific knowledge of fencing. In that his life has been isolated and studied the most important facts that stand out above all, is that he was considered to be the inventor of swordmanship and the particular manner of interpreting the said art, different to its interpretaion uptil then. It gave a footing to what they understood as scientific fencing, giving shape and form to the creation of a doctrine and a new form of fencing which developed a line of action that was continued by numerious followers. For all that, much had to do with the facts that Carranza was a military man, the culture, the level of studies he had and the situation in which he found himself. What's more the people with whom he mixed were, in general, cultured and of high social standing. We have also seen in the same article on his life some dubious facts which in our opinión are erróneos. We have considered the most relevent to be that it wasnt Carranza who was in dispute with Quevedo as is stated in some of the works with which we have dealt but rather it was with Pacheco he had such disputes. What's more Quevedo demonstrated his partiality to the teachings of Carranza, going against Pacheco ñor was it him who invented The Florete, a famous Spanish sword, as was said on some ocassions, eventhough the florete appeared later as a weapon in the study of fencing technique. With respect to the article on his works, we must say that there was only one article which was published in 1582, even though it was finished in 1569. In the article on his life one must distinguish between the foundations on which he based his teachings in which swordmanship reached the same levéis as other libral art forms and what he did through the study of the self same mastery. Throughout the study which we have done, one can appreciate how he was developing an art which uptill then had not been studied, seeing for himself the problems he had fortold, from the organisation of materials at hand to how it should be taught, at times having to domínate comparative concepts again or clarify and modify ones which were anchored in erróneos points of a fencing match, feeling these to be the main forseeable jobs-at-hand. Differenciating between two basic concepts which must exist in whatever arte form and more concretly in the skill that is; the theory and practice , both being fundamental to the reason why the skill endured through time, together with this reason he was supported by other sciences and the beginnings of such. Carranza was of the opinión that the swordsman must acquired by way of study, the fundemental elements with which he had to work, these elements being the body of the swordsman and the weapons, because both were going to intervene in whatever movement or action that was going to be taken. The body studied, each of the parts having more importance each time the skill intervened and above all what it did based on medicne relating it to matemathics to exact the máximum advantage, one could employ in certain circumstances, that if they were not employed, the same advantages would not result. On weapons, what resulted best was, on the one hand, the sword should be the only weapon that the swordsman should use and on the other hand, the sword should be graded to show that one cannot do the same with the different parts of the same because not all of the weapon had the same properties when used. One of the recomendations he made was that the part nearest to the hand-guard should be used for defence because one could use more forcé with it than the point and he demonstrated this with mathematical principies. One can see on reading this thesis how Carranza brought forth a new work form, in which he put much importance on the application of experience that had previously been acquired and because of it, it was important to know well the strenghts and weaknesses of an adversery. The acquisition of technique should be realised through repetition to form the habit necessary for movement to flow freely each time the swordsman executed a movement. None of this would be possible if whoever was teaching did not know each one of the elements that intervened, affording the fencing master a great reverence, in that it was he who had to guide the students he was to teach. The first thing that the master had to do was to make sure he had the maximun knowledge over which he was going to teach, to that end, the master had to know almost everything about the theory and practice of the skill of fencing but what's more that such theory and practice had to be the correct one. Carranza persued his studies, establishing the principies of technique, at least, the most important ones even though they were elementary, so that later they could continué working on them and it could be seen that the technique had a shape and form of any other art form, allowing it to be studied like any other form, as such it had a good following, even young people could be instructed in the correct use of weapons, however the real end could be found in the conservaron of life as ordered by the Catholic Church, feeling that skill with the sword was one of the most effective methods for assuring it. We have dedicated an article to technique and tactics wherein is reflected everything related to positions and movement that the swordsman must do to achieve his objective, that is, wound without being wounded. We have analised the different tricks and the reasons from every point of view of movement and action. If what is done by technique is related with the adversery we enter in the territory of tactics wherein we have studied, most importantly, the concepts of time and distance just as, the energy the swordsman muse conserve to bring to a head a bout and arrive victorious without being exhausted. We conclude by saying that everything that has been realised by this study, has shown that it was Carranza who gave to the skill, the first basic techniques, tactics and methodology, by his conception of this new art form, just as the manner in which he established his theories, made possible the tecnhiques practiced in Spain would enjoy an intemal coherent structure, which would endure throughout the years.

Targeted deletion of the mouse POU domain gene Brn-3a causes selective loss of neurons in the brainstem and trigeminal ganglion, uncoordinated limb movement, and impaired suckling.

The Brn-3 subfamily of POU domain genes are expressed in sensory neurons and in select brainstem nuclei. Earlier work has shown that targeted deletion of the Brn-3b and Brn-3c genes produce, respectively, defects in the retina and in the inner ear. We show herein that targeted deletion of the Brn-3a gene results in defective suckling and in uncoordinated limb and trunk movements, leading to early postnatal death. Brn-3a (-/-) mice show a loss of neurons in the trigeminal ganglia, the medial habenula, the red nucleus, and the caudal region of the inferior olivary nucleus but not in the retina and dorsal root ganglia. In the trigeminal and dorsal root ganglia, but not in the retina, there is a marked decrease in the frequency of neurons expressing Brn-3b and Brn-3c, suggesting that Brn-3a positively regulates Brn-3b and Brn-3c expression in somatosensory neurons. Thus, Brn-3a exerts its major developmental effects in somatosensory neurons and in brainstem nuclei involved in motor control. The pheno-types of Brn-3a, Brn-3b, and Brn-3c mutant mice indicate that individual Brn-3 genes have evolved to control development in the auditory, visual, or somatosensory systems and that despite differences between these systems in transduction mechanisms, sensory organ structures, and central information processing, there may be fundamental homologies in the genetic regulatory events that control their development.

Sintomas de estresse e percepção de estressores escolares no início do Ensino Fundamental

O ingresso no Ensino Fundamental - EF tem sido visto como um momento de transição devido às novas demandas que apresenta para a criança. Neste contexto, parece haver um aumento da vulnerabilidade das crianças ao estresse, principalmente daquelas com maior dificuldade de adaptação a estas demandas. Esse estudo teve como objetivo amplo investigar o estresse da transição no contexto do EF de nove anos, partindo de uma visão desenvolvimentista aliada a uma perspectiva de exposição a estressores cotidianos. Especificamente, o estudo investigou a relação entre competências e sintomas de estresse no 1º ano do EF, o curso desenvolvimental dos sintomas e das percepções de estresse nos dois anos inicias do EF, suas associações com as tarefas adaptativas da transição e a influência da escola nos indicadores de estresse. Finalmente, exploraram-se modelos explicativos para indicadores de estresse apresentados no 2º ano. Seguindo metodologia prospectiva, avaliaram-se indicadores de ajustamento e competências relacionadas ao desempenho acadêmico, social e comportamental das crianças no 1º ano, estresse nos dois primeiros anos e características da escola (localização e IDEB). Participaram da pesquisa 157 alunos do 1º ano do EF, sendo 85 meninos e 72 meninas, com idade média de 6 anos e 10 meses no início da pesquisa. Todos tinham experiência de dois anos na Educação Infantil e estavam matriculados em escolas municipais de diferentes regiões de uma cidade do interior de São Paulo. Também participaram do estudo, como informantes, seus respectivos professores do 1º ano, num total de 25. As crianças responderam à Escala de Stress Infantil, ao Inventário de Estressores Escolares e a uma avaliação objetiva de desempenho acadêmico (Provinha Brasil). Os professores avaliaram as habilidades sociais, os problemas de comportamento externalizantes e internalizantes e a competência acadêmica dos seus alunos por meio do Social Skills Rating System Professores. A análise dos dados compreendeu estatísticas descritivas, comparações, correlações e regressões. Nos resultados, 57% dos alunos no 1º ano e 72% no 2º ano relataram sintomas de estresse pelo menos na fase de alerta. Crianças com estresse no 1º ano apresentaram menores índices de ajustamento e competência e perceberam suas escolas como mais estressantes em relação ao seu papel de estudante e nas relações interpessoais. Correlações moderadas entre medidas de indicadores de estresse tomadas no 1º e no 2º ano sugerem estabilidade. A presença de sintomas de estresse aumentou do 1º para o 2º ano, enquanto a percepção de estressores escolares não variou. Crianças com maiores médias de estresse são provenientes de escolas situadas em regiões periféricas e com classificação mais baixa no IDEB. As análises de predição evidenciaram a habilidade social de responsabilidade e cooperação avaliada no 1º ano como importante fator de proteção contra sintomas de estresse no 2º ano, ao passo que a percepção da criança de tensões nas relações interpessoais no 1º ano foi o principal fator de risco para futura sintomatologia de estresse. Nesse sentido, intervenções com ênfase na promoção de habilidades sociais das crianças podem ser profícuas na prevenção do estresse.

Software for "Realistic limits for subpixel movement detection"

Object tracking with subpixel accuracy is of fundamental importance in many fields since it provides optimal performance at relatively low-cost. Although there are many theoretical proposals that lead to resolution increments of several orders of magnitude, in practice, this resolution is limited by the imaging systems. In this paper we propose and demonstrate through numerical models a realistic limit for subpixel accuracy. The final result is that maximum achievable resolution enhancement is connected with the dynamic range of the image, i.e. the detection limit is 1/2^(nr.bits). Results here presented may help to proper design of superresolution experiments in microscopy, surveillance, defense and other fields.

Music and movement: A comparative study between the BAPNE and Suzuki Methods

The aim of this article is to compare the Suzuki and BAPNE methods based on bibliography published for both approaches. In the field of musical and instrumental education and especially for the childhood stage, the correct use of the body and voice are of fundamental importance. These two methods differ from one another; one principally musical and instrumental, which is the Suzuki method, and one non-musical, the BAPNE method, which aims at stimulating attention, concentration, memory and the executing function of the pupil through music and body percussion. Comparing different approaches may provide teachers with a useful insight for facing different issues related to their discipline.

Fundamental rights in the EU: three years after Lisbon, the Luxembourg perspective. Research Paper in Law (Cooperative Research Paper) 02/2013

For more than 10 years after the signature of the Treaty of Rome in 1957, the question of the protection of human rights had never been in issue. The emphasis was on the creation and consolidation of the common market establishing the free movement of persons, of services, of goods and of capital. Neither the initial Treaties nor the jurisprudence of the Court made any reference to the protection of human rights in the process of the creation of the common market. It all started in 1969 in the Stauder case with this very short sentence: “Interpreted in this way the provision at issue contains nothing capable of prejudicing the fundamental human rights enshrined in the general principles of Community law and protected by the Court”. Forty years later, with the adoption of the Treaty of Lisbon, which came into force on 1 December 2009, fundamental rights are part of primary law. The achievement has been remarkable if we consider the very beginning of the process. It is not an exaggeration to say that the Court with its jurisprudence has been the driving force and the source of inspiration for this achievement.

Free movement of workers in the EU. Legal aspects of the transitional arrangements. ZEI Discussion Paper No. 217, 2013

From the Introduction. There are four fundamental freedoms which lay the foundation of the European Union. Those are the free movement of goods, free movement of capital, free movement of services and free movement of persons. They guarantee the existence and effective functioning of an area without internal borders within which goods, capital, services and people move freely. Despite the pivotal importance of these freedoms, there are cases where some freedoms can be partially or fully restricted within the territory of some member states or the Union as a whole. This thesis is going to analyze the restrictions of one of these freedoms: the free movement of persons, resulting from the arrangements applying to new member states. The focus will be the free movement of workers from new to old member states for a transitional period following the date of accession.

Frontex and the respect of fundamental rights: from better protection to full responsibility. EPC Policy Brief, 3 June 2014

The European Agency for the Management of Operational Cooperation at the External Borders of the Member States of the European Union (Frontex) was created to improve border management cooperation between Member States. Seen from its inception as a security-oriented body, tools and rules have been gradually developed to enhance the human rights dimension and protection regarding Frontex activities. However, this step has not been accompanied with the explicit recognition of Frontex’s legal responsibility regarding violations of human rights occurring during joint operations it coordinates. Despite Frontex position rejecting such a responsibility, it is no longer clear whether this position can be maintained, as Yves Pascouau and Pascal Schumacher demonstrate in this Policy Brief.

Freedom of movement of persons - the building block of European growth. CHALLENGE EUROPE Issue 22 - Challenges and new beginnings: Priorities for the EU's new leadership, September 2014.

The European integration project is founded on values and principles which are simple, equal, and advantageous for all. Freedom of movement of persons is one of the main cornerstones of EU success. It is a fundamental, cherished right of EU citizens. Thanks to this liberty, European citizenship is real, concrete and attractive. Moreover, it spurs economic growth and technological development. But because freedom of movement has become an obvious feature of our day-to-day lives, some of us tend to underestimate its consequences. Important recent developments mean that we must renew our commitment to defend this building-block of a Europe whole and free.
