Rethinking the Finance of Post-Compulsory Education
2010
Throughout the world, the finance of education is in serious crisis. The crisis of educational finance is not limited to the problem of meeting the obligations of societies to provide some minimum amount of compulsory education for their students. This minimum does not assure the preparation of an appropriately trained labour force in a world that is increasingly technicological and in which a competitive economy requires the remplacement of traditional production processes with others based on sophisticated labour and capital. The rapid growth of post-compulsory systems of education is no longer a luxury, but a necessity for industrialization and economic development.
On the mechanics of progress in primary education
2003
03045; International audience; As countries grow rich, education improves in many ways. The sector enjoys more resources for education per primary school-aged child, not because of bigger budget allocations, nor an easing of the demographic burden on the system, but because the cost of inputs, especially teacher salaries, decline substantially relative to the per capita GNP. The extra resources enable countries to expand coverage and reduce the pupil–teacher ratio, with the latter receiving increasing emphasis during the past 20 years. The implicit trade-off against coverage raises questions about the efficiency and equity of education policies in developing countries, particularly in setti…
Software Defined Machine-to-Machine Communication for Smart Energy Management in Power Grids
2020
The successful realization of smart energy management relies on ubiquitous and reliable information exchange among millions of sensors and actuators deployed in the field with little or no human intervention. This motivates us to introduce a unified communication framework for smart energy management by exploring the integration of software-defined networking (SDN) with M2M communication. In this chapter, the overall design of the software-defined M2M (SD-M2M) framework is presented, with an emphasis on its technical contributions to cost reduction, fine granularity resource allocation, and end-to-end QoS guarantee. Then, a case study is conducted for a electric vehicle energy management sy…
A novel frequency reuse scheme for coordinated multi-point transmission
2010
La transmisión multipunto coordinada (CoMP) se considera en 3GPP LTE-Advanced como una técnica clave para mejorar el rendimiento en el borde de la célula. Con el fin de apoyar la asignación conjunta de asignación de recursos entre células coordinadas en sistemas CoMP, es necesario diseñar esquemas eficientes de reutilización de frecuencias. Sin embargo, la mayoría de los esquemas de reutilización de frecuencias existentes no son adecuados para transmisión CoMP debido a que no consideran el escenario de transmisión conjunta multicelular en su regla de reutilización de frecuencias. Para resolver este problema, en este trabajo se propone un esquema de reutilización de frecuencias que divide el…
Energy Efficient Resource Allocation for OFDMA Two-Way Relay Networks with Channel Estimation Error
2015
In this work, we consider the practical issues of resource allocation problem in OFDMA two-way relay networks: the inaccuracy of channel-state information (CSI) available to the transmitters. Instead, only the estimated channel status is known by the transmitters. In this context, a joint optimization of subcarrier pairing and allocation, relay selection and transmit power allocation is formulated in the OFDMA two-way amplify-and-forward relay networks. Moreover, to ensure the Quality of Service (QoS) requirement, the energy consumption must be minimized without compromising the QoS. Therefore, by applying convex optimization techniques, energy efficient algorithms are developed with the ob…
Capture Aware Sequential Waterfilling for LoraWAN Adaptive Data Rate
2020
LoRaWAN (Long Range Wide Area Network) is emerging as an attractive network infrastructure for ultra low power Internet of Things devices. Even if the technology itself is quite mature and specified, the currently deployed wireless resource allocation strategies are still coarse and based on rough heuristics. This paper proposes an innovative "sequential waterfilling" strategy for assigning Spreading Factors (SF) to End-Devices (ED). Our design relies on three complementary approaches: i) equalize the Time-on-Air of the packets transmitted by the system's EDs in each spreading factor's group; ii) balance the spreading factors across multiple access gateways, and iii) keep into account the c…
A Comprehensive Utility Function for Resource Allocation in Mobile Edge Computing
2020
In mobile edge computing (MEC), one of the important challenges is how much resources of which mobile edge server (MES) should be allocated to which user equipment (UE). The existing resource allocation schemes only consider CPU as the requested resource and assume utility for MESs as either a random variable or dependent on the requested CPU only. This paper presents a novel comprehensive utility function for resource allocation in MEC. The utility function considers the heterogeneous nature of applications that a UE offloads to MES. The proposed utility function considers all important parameters, including CPU, RAM, hard disk space, required time, and distance, to calculate a more realis…
Financing for quality : a new deal in Spanish higher education
1996
In recent years, higher education in Spain has undergone major legal and organizational changes. The number of students and the resources committed to higher education has also grown dramatically in the last decade. After this period of rapid changes, the Spanish Public Higher Education System (SPHES) is launching mechanisms to improve overall efficiency and quality. To meet these objectives, three programs are being carried out: first, a new organization of the teaching system, which aims to make the programs more flexible, varied, of shorter duration and more closely related to social needs; second, a program to assess the quality of university institutions; and, third, a new model to fin…
Germany: Where Are We Going?
2012
Germany’s health policy, in the past, has tried to limit health expenditures by defining an overall health budget, by installing a DRG-system and by forcing patients to participate directly at health costs by demanding copayments. These measurements were somehow effective in keeping premiums stable but have led to resource allocation at the bedside and therefore on an implicit level. Yet, implicit-level decisions create ethical dilemmas for physicians as they not only have to deliver best medical care but shall also have cost in mind, are unjust because rationing criteria differ from one case to another, and create a general fear of legal uncertainty, in turn leading to defensive medicine w…
