Drift Tubes Trigger System of the CMS Experiment at LHC : Commissioning and Performances

In this thesis the performances of the CMS Drift Tubes Local Trigger System of the CMS detector are studied. CMS is one of the general purpose experiments that will operate at the Large Hadron Collider at CERN. Results from data collected during the Cosmic Run At Four Tesla (CRAFT) commissioning exercise, a globally coordinated run period where the full experiment was involved and configured to detect cosmic rays crossing the CMS cavern, are presented. These include analyses on the precision and accuracy of the trigger reconstruction mechanism and measurement of the trigger efficiency. The description of a method to perform system synchronization is also reported, together with a comparison of the outcomes of trigger electronics and its software emulator code.

Pratiche del possibile: i Participatory Guarantee Systems e le scelte d'acquisto del consumatore brasiliano

Negli ultimi anni, parallelamente all’espansione del settore biologico, si è assistito a un crescente interesse per i modelli alternativi di garanzia dell’integrità e della genuinità dei prodotti biologici. Gruppi di piccoli agricoltori di tutto il mondo hanno iniziato a sviluppare approcci alternativi per affrontare i problemi connessi alla certificazione di terza parte. Queste pratiche sono note come Sistemi di Garanzia Partecipativa (PGS). Tali modelli: (i) si basano sugli standard di certificazione biologica dell’IFOAM, (ii) riguardano il complesso dei produttori di una comunità rurale, (iii) comportano l’inclusione di una grande varietà di attori e (iv) hanno lo scopo di ridurre al minimo burocrazia e costi semplificando le procedure di verifica e incorporando un elemento di educazione ambientale e sociale sia per i produttori sia per i consumatori. Gli obiettivi di questo lavoro di ricerca: • descrivere il funzionamento dei sistemi di garanzia partecipativa; • indicare i vantaggi della loro adozione nei Paesi in via di sviluppo e non; • illustrare il caso della Rede Ecovida de Agroecologia (Brasile); • offrire uno spunto di riflessione che riguarda il consumatore e la relativa fiducia nel modello PGS. L’impianto teorico fa riferimento alla Teoria delle Convenzioni. Sulla base del quadro teorico è stato costruito un questionario per i consumatori con lo scopo di testare l’appropriatezza delle ipotesi teoriche. I risultati finali riguardano la stima del livello di conoscenza attuale, la fiducia e la volontà d’acquisto dei prodotti PGS da parte dei consumatori nelle aree considerate. Sulla base di questa ricerca sarà possibile adattare ed esportare il modello empirico in altri paesi che presentano economie diverse per cercare di comprendere il potenziale campo di applicazione dei sistemi di garanzia partecipativa.

The informal market of education in Egypt: Private tutoring and its implications /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 88

Education is generally perceived as a public good which should be provided by the state. In Egypt, free and equal access to education has been guaranteed to all citizens since President Nasser’s socialist reforms in the 1950s. However, due to high population growth rates and a lack of financial resources, the public education system has been struggling to accommodate rapidly increasing numbers of students. While enrolment rates have risen steadily, the quality of state-provided services has deteriorated. Teachers and students have to cope with high class densities, insufficient facilities, a rigid syllabus and a centralized examination system. Today, teaching is among the lowest-paying occupations in the public sector. One strategy to cope with this situation is the widespread practice of private tutoring, which usually takes place at students’ homes or in commercial tutoring centers. Based on research carried out in Cairo in 2004/05 and 2006, I use an actor-centered approach to analyze the motivations of Egyptian teachers and students for participating in private tutoring and the impact that this practice has on the relationship between teachers and students. Students of all socio-economic backgrounds resort to tutoring in order to succeed in a highly competitive and exam-oriented education system. However, the form and quality of tutoring that can be accessed depends on the financial means of the family. For teachers, tutoring provides a good opportunity not only to supplement their income, but also, in the case of renowned “star teachers”, to improve their professional status and autonomy. On the informal “market of education” that has developed in Egypt during the last decades, the educational responsibilities of the state are increasingly being taken over by private actors, i.e. the process of teaching and learning is dissociated from the direct control of the state and from school as an institution. At the same time, education is turned into a marketable commodity. Despite the government’s efforts to provide free education to all citizens, the quality of social services that can be accessed in Egypt, thus, depends mainly on the financial means of the individual or the family.

La promozione dell'inclusione nei sistemi scolastici attraverso l'intervento di cooperazione internazionale: l'esperienza di El Salvador

La ricerca si colloca all’interno di un complesso intervento di cooperazione internazionale realizzato in El Salvador tra il 2009 e il 2014. Il Progetto di cooperazione è stato promosso dal Dipartimento di Scienze dell’Educazione dell’Università di Bologna e finanziato dalla Cooperazione Italiana. L’esperienza studiata rappresenta un esempio di promozione dell’inclusione nei sistemi scolastici di Paesi del Sud del mondo e si propone due obiettivi: 1) analizzare il processo di cambiamento della prospettiva di intervento promossa dalla cooperazione internazionale, evidenziando la dimensione educativa che sostiene processi di empowerment e ownership delle istituzioni locali; 2) contribuire al dibattito sull’ “inclusive education”, sostenendo processi di inclusione scolastica e sociale rivolti a tutti coloro che si trovano in situazione di svantaggio psico-fisico e/o socio-culturale. Le politiche locali del Ministero dell’Educazione dal 2009 hanno promosso un modello educativo con l’obiettivo di garantire il diritto all’educazione per tutti nella scuola pubblica. Lo studio costituisce un'indagine di tipo valutativo sul processo di sviluppo della scuola inclusiva in El Salvador, supportato dall’intervento di cooperazione internazionale. La ricerca utilizza in modo integrato strumenti di natura quantitativa (questionari) e qualitativa (interviste). Dai dati raccolti emerge come il processo di cooperazione sia stato caratterizzato dal principio della pari dignità tra esperti internazionali e autorità politiche e tecniche locali. Inoltre, la ricerca ha consentito di verificare come la cultura dell'inclusione si sia radicata in modo diffuso nella percezione della missione della scuola e il suo ruolo tra i protagonisti del sistema scolastico. Alla luce dei risultati, appare fondamentale continuare a investire sulla formazione tecnica delle figure chiave del sistema educativo; facilitare il processo di inclusione dei disabili nelle scuole regolari con una parallela trasformazione delle scuole speciali in centri di supporto all’integrazione; promuovere una sinergia di azione formativa tra il ministero, mondo accademico e della formazione professionale.

Isolated Islands? Memory of the Holocaust in Formal and Non-Formal Education. The Case Study of Post-Communist Poland

Existing studies revealed several conflicts around the memory of the Holocaust in Poland: between understanding the need to teach about the Holocaust and indifference toward anti-Jewish graffiti; a conflict around the perception of Polish help to Jews; and the competing images of Polish and Jewish suffering during World War II. Those conflicts will be addressed in the paper as reflecting educational gaps in the Polish education system (lack of bad memory). This paper will look at the consciousness of young Poles, in terms of attitudes toward Jews, the Holocaust and memory of the Holocaust. The data presented are the preliminary results of the author’s longitudinal study „Attitudes of Young Poles toward the Jews and the Holocaust”. Quantitative and qualitative studies include field studies and participant observation of educational projects in Tykocin, Treblinka, Warsaw, Lublin, Bodzentyn and Kielce. The paper will present some components of the development of education about the Holocaust in Poland. There is a need to evaluate the attempt to bring back the memory of Jewish neighbours in some of the states of Central and Eastern Europe, a process with an ongoing effort to renovate monuments, destroyed cemeteries and synagogues. The number and scope of such initiatives in Poland indicate that civic institutions and individuals are intensifying their efforts to teach their fellow citizens about the Holocaust, however their impact should be assessed in detail.

Algorithms for spacecraft formation flying navigation based on wireless positioning system measurements

Spacecraft formation flying navigation continues to receive a great deal of interest. The research presented in this dissertation focuses on developing methods for estimating spacecraft absolute and relative positions, assuming measurements of only relative positions using wireless sensors. The implementation of the extended Kalman filter to the spacecraft formation navigation problem results in high estimation errors and instabilities in state estimation at times. This is due tp the high nonlinearities in the system dynamic model. Several approaches are attempted in this dissertation aiming at increasing the estimation stability and improving the estimation accuracy. A differential geometric filter is implemented for spacecraft positions estimation. The differential geometric filter avoids the linearization step (which is always carried out in the extended Kalman filter) through a mathematical transformation that converts the nonlinear system into a linear system. A linear estimator is designed in the linear domain, and then transformed back to the physical domain. This approach demonstrated better estimation stability for spacecraft formation positions estimation, as detailed in this dissertation. The constrained Kalman filter is also implemented for spacecraft formation flying absolute positions estimation. The orbital motion of a spacecraft is characterized by two range extrema (perigee and apogee). At the extremum, the rate of change of a spacecraft’s range vanishes. This motion constraint can be used to improve the position estimation accuracy. The application of the constrained Kalman filter at only two points in the orbit causes filter instability. Two variables are introduced into the constrained Kalman filter to maintain the stability and improve the estimation accuracy. An extended Kalman filter is implemented as a benchmark for comparison with the constrained Kalman filter. Simulation results show that the constrained Kalman filter provides better estimation accuracy as compared with the extended Kalman filter. A Weighted Measurement Fusion Kalman Filter (WMFKF) is proposed in this dissertation. In wireless localizing sensors, a measurement error is proportional to the distance of the signal travels and sensor noise. In this proposed Weighted Measurement Fusion Kalman Filter, the signal traveling time delay is not modeled; however, each measurement is weighted based on the measured signal travel distance. The obtained estimation performance is compared to the standard Kalman filter in two scenarios. The first scenario assumes using a wireless local positioning system in a GPS denied environment. The second scenario assumes the availability of both the wireless local positioning system and GPS measurements. The simulation results show that the WMFKF has similar accuracy performance as the standard Kalman Filter (KF) in the GPS denied environment. However, the WMFKF maintains the position estimation error within its expected error boundary when the WLPS detection range limit is above 30km. In addition, the WMFKF has a better accuracy and stability performance when GPS is available. Also, the computational cost analysis shows that the WMFKF has less computational cost than the standard KF, and the WMFKF has higher ellipsoid error probable percentage than the standard Measurement Fusion method. A method to determine the relative attitudes between three spacecraft is developed. The method requires four direction measurements between the three spacecraft. The simulation results and covariance analysis show that the method’s error falls within a three sigma boundary without exhibiting any singularity issues. A study of the accuracy of the proposed method with respect to the shape of the spacecraft formation is also presented.

Present at the Creation: Montana Higher Education Reforms from 1972 Constitution -- Dr. Lawrence K. Pettit “In the Crucible of Change”

Prior to the passage of the 1972 Constitution, Montana’s higher education system was both controlled and victimized by Montana’s politics. Alternatingly, Governors or the Legislature tried to control and/or impose political ideology upon the management and teaching/content within the University System. Political favoritism and power-broking were the hallmark of the legislative appropriation process. Under the new Constitution, a newly empowered Board of Regents, and a new Commissioner of Higher Education managed the system and controlled the allocation of the legislative appropriations, but not without a major battle before the Montana Supreme Court. Dr. Lawrence K. Pettit (Larry Pettit) (b. 5/2/1937) was present at the creation of this newly structured higher education system as the first Commissioner of Higher Education in Montana after his appointment by the Board of Regents of the University System in 1973. Larry Pettit has had a dual career in politics and higher education. Pettit, of Lewistown, served as legislative assistant to U.S. Senators James E. Murray and Lee Metcalf, campaign manager, head of transition team and assistant to Montana Governor Thomas L. Judge, taught political science at The Pennsylvania State University (main campus), was chair of political science at Montana State University, Deputy Commissioner for Academic Programs at the Texas Higher Education Coordinating Board, Chancellor of the University System of South Texas (since merged with Texas A&M University), President of Southern Illinois University, and President of Indiana University of Pennsylvania from where he retired in 2003. He has served as chair of the Commission on Leadership for the American Council on Education, president of the National Association of (University) System Heads, and on many national and state boards and commissions in higher education. Pettit is author of “If You Live by the Sword: Politics in the Making and Unmaking of a University President.” More about Pettit is found at http://www.lawrencekpettit.com

Aussichten der freien Schulwahl. Die globale pädagogische Reformbewegung im Härtetest der direkten Demokratie

Weltweit ist eine Angleichung von Bildungsreformen zu beobachten, was im Begriff der globalen pädagogischen Reformbewegung zum Ausdruck kommt. Obwohl die Bedingungen, unter denen sich Nationalstaaten einer pädagogischen Weltkultur angleichen, in jüngster Zeit vermehrt untersucht wurden, ist über die politischen Mechanismen, die über die Rezeption globaler Modelle befinden, wenig bekannt. Anhand einer Fallstudie aus der Schweiz, deren System der direkten Demokratie besonders geeignet scheint, politische Transformationsprozesse zu untersuchen, wird die Auseinandersetzung um die Einführung der freien Schulwahl, wie sie durch verschiedene Volksinitiativen ausgelöst wurde, rekonstruiert. Die Studie zeigt, dass ein neoinstitutionalistischer Ansatz geeignet sein kann, die Rezeption globaler Reformmodelle zu erklären, sofern er um eine akteurtheoretische Perspektive ergänzt wird und die Besonderheiten des lokalen politischen Systems berücksichtigt werden. In methodischer Hinsicht ergibt sich, dass bei der Untersuchung globaler Angleichungsprozesse vier Referenzpunkte zu beachten sind, nämlich Staat, Markt, Öffentlichkeit und Wissenschaft

Gender Segregation in Vocational Education: Introduction

This introductory chapter develops the overall research focus and the aim of the present special issue ‘Gender segregation in vocational education’. Against the backdrop of strong horizontal gender segregation in vocational education and training (VET), we ask how institutional arrangements affect gendered (self-)selection into VET, and to what extent the patterns of the latter vary by context and over time. In order to expand our knowledge about the impact of educational offers and policies on gendered educational pathways and gender segregation in the labour market, we have gathered comparative quantitative studies that analyse the relationship between national variations in the organization of VET and cross-national differences in educational and occupational gender segregation from an institutional perspective. Following a review of the core literature within the field of gender segregation in VET, this introduction presents a discussion of education system classifications and institutional level mechanisms based on the contributions made in this volume. We then discuss gendered educational choices at the individual level, with particular emphasis on variation across the life course. Finally, we conclude our introductory chapter by commenting on the main contributions of the volume as a whole, as well as addressing suggestions for further research.

The Role for Virtual Patients in the Future of Medical Education

The medical education community is working-across disciplines and across the continuum-to address the current challenges facing the medical education system and to implement strategies to improve educational outcomes. Educational technology offers the promise of addressing these important challenges in ways not previously possible. The authors propose a role for virtual patients (VPs), which they define as multimedia, screen-based interactive patient scenarios. They believe VPs offer capabilities and benefits particularly well suited to addressing the challenges facing medical education. Well-designed, interactive VP-based learning activities can promote the deep learning that is needed to handle the rapid growth in medical knowledge. Clinically oriented learning from VPs can capture intrinsic motivation and promote mastery learning. VPs can also enhance trainees' application of foundational knowledge to promote the development of clinical reasoning, the foundation of medical practice. Although not the entire solution, VPs can support competency-based education. The data created by the use of VPs can serve as the basis for multi-institutional research that will enable the medical education community both to better understand the effectiveness of educational interventions and to measure progress toward an improved system of medical education.

Achieving Universal Primary Education: Can Kenya Afford it?

Kenya has experienced a rapid expansion of the education system partly due to high government expenditure on education. Despite the high level of expenditure on education, primary school enrolment has been declining since early 1990s and until 2003 when gross primary school enrolment increased to 104 percent after the introduction of free primary education. However, with an estimated net primary school enrolment rate of 77 percent, the country is far from achieving universal primary education. The worrying scenario is that the allocations of resources within the education sector seems to be ineffective as the increasing expenditure on education goes to recurrent expenditure (to pay teachers salaries). Kenya's Poverty Reduction Strategy Paper (PRSP) and the Economic Recovery Strategy for wealth and Employment Creation (ERS) outlines education targets of reaching universal primary education by 2015. The Government is faced with budget constrains and therefore the available resources need to be allocated efficiently in order to realize the education targets. The paper uses Budget Negotiation Framework (BNF) to analyze the cost effective ways of resource allocation in the primary education sector to achieve universal primary education and other education targets. Budget Negotiation Framework is a tool that aims at achieving equity and efficiency in resource allocation. Results from the analysis shows that universal primary education by the year 2015 is a feasible target for Kenya. The results also show that with a more cost- effective spending of education resources - increased trained teachers, enhanced textbook supplies and subsidies targeting the poor - the country could realize higher enrolment rates than what has been achieved with free primary education.

Human Capital Externalities and Private Returns to Education in Kenya

We use micro data to analyse the effect of human capital externality on earnings and private returns to education. The earnings equations are estimated using the OLS method for a sample of full-time workers. The results show that human capital has a positive effect on earnings, indicating that an increase in education benefits all workers. However, men benefit more from women's education than the women do from men's. The effects of human capital externality on private returns to schooling are shown to vary substantially between rural and urban areas and across levels of the education system.
