Understanding short- and long-term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company
2010
Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long-term sustainable policies quite difficult. In fact, the result may be that decision makers introduce "effective" policies in a company subsystem, while ignoring the medium- and long-term implications of such decisions in the performance of the whole company. With the aim to detect the main causes underlying "myopic" fleet maintenance polici…
Enhanced TESF methodology for course excellence
2010
The need to achieve the excellence in services provided by a University has been object of study and research for several decades. Often, the focus is not only on the education service, but on several satellite services provided by a university. This article focuses on teaching, considered as a central service, believing (the authors) that the improvement actions of an academic institution should always start from this service. The work proposes the implementation of a tool able to measure student perceptions on certain selected aspects of the course. This tool is part of the Teaching Experiment and Student Feedback (TESF) methodology previously developed by the authors. Here, the steps to …
Statistical properties of a new student satisfaction index
2010
Quality of Higher Education is increasingly important in all developed countries. In fact quality and reputation are key elements to control the flow of students at national and international level. The authors have shown that quality of education can be improved through a process of self-assessment of the teaching services and a well studied analysis of the student feedback. In particular a new student satisfaction index was formulated which allows student feedback being summarised and interpreted for a continuous course improvement. In this paper some statistical properties of the student satisfaction index are illustrated, and comparisons with other measures based on Likert scales are ma…
Didaktiskās spēles kā vārdu krājuma sekmētājas 5-6 gadus veciem bērniem
2017
Bakalaura darbs ,,Didaktiskās spēles kā vārdu krājuma sekmētājas 5-6 gadus veciem bērniem” ir par vārdu krājuma pilnveidošanas iespējām bērniem 5-6 gadu vecumā, izmantojot didaktiskās spēles. Pētījuma mērķis: Izpētīt 5-6 gadus vecu bērnu vārdu krājuma bagātināšanas iespējas, izmantojot didaktiskās spēles. Pirmsskolas vecumā galvenais mācību darbības veids ir rotaļa. Rotaļu, spēļu laikā bērns iegūst jaunas zināšanas, prasmes, attieksmes. Bērns didaktisko spēļu laikā mācās apgūt jaunus vārdus, darina jaunus vārdus, domā teikumus, stāstus, tātad - mācās. Bērns jaunās prasmes apgūst rotaļājoties. Vārdu krājuma pilnveidošana ir viens no būtiskākajiem uzdevumiem darbā ar pirmsskolas vecuma bērnie…
TESF Methodology for Statistics Education Improvement
2010
The need for universities to achieve excellence in the services they provide has been the subject of research for several decades. The idea of involving students and recognizing the importance of their opinions has led to the creation of various models and tools. This paper focuses on teaching, a central service from which improvement actions of an academic institution should always begin. The article reviews and updates the previously developed Teaching Experiments and Student Feedback methodology. The methodology, which is primarily addressed to statistics teachers, allows practical aspects to be organized and decisions to be made based on data that has been collected from students and sc…
Mapping 123 million neonatal, infant and child deaths between 2000 and 2017
2019
Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained ra…
A reexamination of voltage distortion for classical carrier-based vs B-Spline modulation of three-phase Voltage Sources Inverters
2015
Voltage waveform improvement has been the object of several investigations for many years and a manifold of different solutions have been proposed to reduce the harmonic content in Voltage Source Inverters (VSI) power application. In many cases this improvements have been obtained by modifying the reference voltage modulating signal. The recent introduction of cardinal B-spline functions, used as carrier signals, has given rise to a new modulation technique whose main characteristic is a lower value of the Total Harmonic Distortion (THD). After the discussion on the B-Spline modulation principle and on its computational effort, a performance comparisons is carried out by means of Total Harm…
Investigating teacher leadership in Cameroon secondary education : a case of two public schools
2018
Teacher leadership is crucial in improving schools and enhancing student learning. In Cameroon, the hierarchical nature of leadership and the internal school structures encourage the partition of roles and responsibilities and a clear separation of power and authority. Teachers in Cameroon work within a more imposed system, where the national curriculum is design and impose on them. As a result, teachers do not perform activities geared towards leadership. To improve on teacher leadership practices in Cameroon and learn from exemplar systems (e.g., Finland), it is important to examine how teacher leadership is practiced and how it can be improved. Accordingly, the purpose of this study is t…
Cultural Heritage As A Driver Of Development
2010
After drawing attention to the importance of cultural heritage, the Authors analyze the inherent problems of the various stages: conservation, valorization and fruition which, interacting and fully respecting the integrity and identity of the asset and its history, can promote local economic development and employment opportunities.
Noncooperative dynamic games for inventory applications: A consensus approach
2008
We focus on a finite horizon noncooperative dynamic game where the stage cost of a single player associated to a decision is a monotonically nonincreasing function of the total number of players making the same decision. For the single-stage version of the game, we characterize Nash equilibria and derive a consensus protocol that makes the players converge to the unique Pareto optimal Nash equilibrium. Such an equilibrium guarantees the interests of the players and is also social optimal in the set of Nash equilibria. For the multi-stage version of the game, we present an algorithm that converges to Nash equilibria, unfortunately not necessarily Pareto optimal. The algorithm returns a seque…
