Changing boundaries in Israeli higher education

This paper analyses the main changes that took place in the Israeli higher education system in the last decades, and accounts for the reconstruction of its external and internal boundaries. It also provides a conceptual framework for comparing national higher education systems from a comparative perspective. The paper examines the developments that characterise the restructuring of the Israeli higher education from an international comparative outlook, and relates to the following parameters: (a) expansion in size; (b) diversification of the higher education institutions; (c) the emergence of new academic fields of study; (d) the upgrade of many professions and occupations to an academic status; (e) the redefinition of graduate degrees; (f) the impact of the new information technologies on shaping academic environments; and (g) the influence of the globalisation and internationalisation trends on the development of national higher education systems.peer-reviewe

Des diplomes algeriens parlent de la formation universitaire

This evaluation of higher education in Algeria was performed by means of open-ended interviews with eight graduates of the University of Constantine. From the beginning of the 1980s, it was found that all disciplines, including Economics, Law, Library Science, and Psychology, showed failures in academic training. A change of direction towards making teaching more rigorous and career-oriented is recommended.peer-reviewe

High Temperature Electron Localization in dense He Gas

We report new accurate mesasurements of the mobility of excess electrons in high density Helium gas in extended ranges of temperature $[(26\leq T\leq 77) K ]$ and density $[ (0.05\leq N\leq 12.0) {atoms} \cdot {nm}^{-3}]$ to ascertain the effect of temperature on the formation and dynamics of localized electron states. The main result of the experiment is that the formation of localized states essentially depends on the relative balance of fluid dilation energy, repulsive electron-atom interaction energy, and thermal energy. As a consequence, the onset of localization depends on the medium disorder through gas temperature and density. It appears that the transition from delocalized to localized states shifts to larger densities as the temperature is increased. This behavior can be understood in terms of a simple model of electron self-trapping in a spherically symmetric square well.Comment: 23 pages, 13 figure

Cavitation of Electrons Bubbles in Liquid Helium Below saturation Pressure

We have used a Hartree-type electron-helium potential together with a density functional description of liquid $^4$He and $^3$He to study the explosion of electron bubbles submitted to a negative pressure. The critical pressure at which bubbles explode has been determined as a function of temperature. It has been found that this critical pressure is very close to the pressure at which liquid helium becomes globally unstable in the presence of electrons. It is shown that at high temperatures the capillary model overestimates the critical pressures. We have checked that a commonly used and rather simple electron-helium interaction yields results very similar to those obtained using the more accurate Hartree-type interaction. We have estimated that the crossover temperature for thermal to quantum nucleation of electron bubbles is very low, of the order of 6 mK for $^4$He.Comment: 22 pages, 9 figure

Detecting Neutral Atoms on an Atom Chip

Detecting single atoms (qubits) is a key requirement for implementing quantum information processing on an atom chip. The detector should ideally be integrated on the chip. Here we present and compare different methods capable of detecting neutral atoms on an atom chip. After a short introduction to fluorescence and absorption detection we discuss cavity enhanced detection of single atoms. In particular we concentrate on optical fiber based detectors such as fiber cavities and tapered fiber dipole traps. We discuss the various constraints in building such detectors in detail along with the current implementations on atom chips. Results from experimental tests of fiber integration are also described. In addition we present a pilot experiment for atom detection using a concentric cavity to verify the required scaling.Comment: 13 pages, 12 figure

Investigating Converted Phases in the Midland Basin, Texas, Using Synthetic Seismograms

Intraplate seismicity in previously aseismic areas within the Permian Basin, Texas, has steadily increased since 2009 (Frohlich et al., 2020). The Midland Basin, the eastern lobe of the Permian, has experienced multiple moderate magnitude earthquakes (M4-6), including the recent 2022 M5.2 Range Hill earthquake. While it is generally accepted that oil and gas development is linked to the seismic activity, and saltwater disposal (SWD) is a significant triggering mechanism in the Midland Basin, understanding the mechanism(s) of shallow
