description: All-day schools are not only meant to improve the individual development of their students, they are also supposed to support parents in reconciling family and work. However, studies on parental acceptance of all-day schools focus primarily on the issue of work-life balance. The opinions of parents with regard to the potential support of allday schools for individual development and educational success of their children have hardly been examined. In this paper, we investigate whether parents regard all-day schools as an opportunity for improving the individual development of their children. For our analyses, we use mainly the data of a survey of parents of students at all-day schools (N=16,261), which was conducted in 2009 within the “Study on the development of all-day schools” (StEG). First of all, our findings show that all-day schools are accepted particularly by East German parents in dualincome households. These parents see all-day schools as an opportunity for both goals, i.e. for a better care as well as a way of enhancing the personal development of their children. This is especially true for parents with a less privileged social background. Zusammenfassung Ganztagsschulen sollen nicht nur eine bessere Förderung der Schülerinnen und Schüler ermöglichen, sondern Eltern auch bei der Vereinbarkeit von Familie und Erwerbstätigkeit unterstützen. Untersuchungen zur Akzeptanz von Ganztagsschulen konzentrieren sich allerdings in erster Linie auf die Vereinbarkeitsproblematik. Die Einschätzungen der Eltern im Hinblick auf das Unterstützungspotenzial von Ganztagsschulen für die individuelle Entwicklung und den schulischen Erfolg ihrer Kinder wurden demgegenüber bisher kaum aufgegriffen. In diesem Beitrag untersuchen wir, welche Teilnahmemotive Eltern mit der Ganztagsschule verbinden und ob diese Erwartungen eingelöst werden. Hierbei wird der Frage nachgegangen, welche Rolle dabei die Bildungsstrategien und der sozio-ökonomische Hintergrund der Eltern spielen. Für unsere Analysen verwenden wir in erster Linie die Daten einer Befragung von Eltern von Schülerinnen und Schülern an Ganztagsschulen (N=16.261), die im Jahr 2009 im Rahmen der „Studie zur Entwicklung von Ganztagsschulen“ (StEG) durchgeführt wurde. Unsere Befunde zeigen zunächst einmal, dass Ganztagsschulen vor allem von ostdeutschen Doppelverdiener- Hauhalten akzeptiert werden. Diese Eltern verbinden mit der Ganztagsschule in gleicher Weise Betreuungs- und Förderungsmöglichkeiten. Das gilt insbesondere auch für Eltern mit weniger günstigen sozialen Voraussetzungen.

description: We study gravity in backgrounds that are smooth generalizations of the Randall-Sundrum model, with and without scalar fields. These generalizations include three-branes in higher dimensional spaces which are not necessarily Anti-de Sitter far from the branes, intersecting brane configurations and configurations involving negative tension branes. We show that under certain mild assumptions there is a universal equation for the gravitational fluctuations. We study both the graviton ground state and the continuum of Kaluza-Klein modes and we find that the four-dimensional gravitational mode is localized precisely when the effects of the continuum modes decouple at distances larger than the fundamental Planck scale. The decoupling is contingent only on the long-range behaviour of the metric from the brane and we find a universal form for the corrections to Newton's Law. We also comment on the possible contribution of resonant modes. Given this, we find general classes of metrics which maintain localized four-dimensional gravity. We find that three-brane metrics in five dimensions can arise from a single scalar field source, and we rederive the BPS type conditions without any a priori assumptions regarding the form of the scalar potential. We also show that a single scalar field cannot produce conformally-flat locally intersecting brane configurations or a p-brane in greater than (p+2)-dimensions.

description: This study aimed to investigate the perceptions of dental students and teachers about introducing metacognition pedagogy within an established clinical professional curriculum to provide primary data informing its feasibility. A qualitative study using phenomenography methodology was undertaken as part of a master’s dissertation. Semi-structured interviews were conducted on 16 participants which included 9 clinical teachers and 7 dental students. Metacognition pedagogy was positively perceived by most of the participants as being beneficial to students’ learning in oral health education. A few reported some negativity. All participants identified some challenges to be addressed if a metacognition pedagogy was to be implemented in the undergraduate curriculum. According to the perceptions of most participants in the study, metacognition emerged as a potential factor in improving student learning and exam performance, and facilitating the development of critical thinking, professionalism, and clinical skills. In the context of rigorous, demanding, and challenging courses, and recognising the complexities and uncertainties inherent in health professional working environments, metacognition emerges as a valuable tool, fostering self-awareness, regulation, and adaptability. Ultimately, metacognition has the capability to shape more adept learners and clinicians, yielding benefits for students, teachers, and patients alike.

description: Although pluralization of life forms and effects of precarious work have recently been matters of debate among scholars in the social sciences, only little is known about the impact of both processes on fertility intentions. Focusing individual attitudes of young German adults towards these issues, this paper investigates whether pluralization of life forms or effects of precarious work lead to lower rates of fertility intentions. Based on social exchange theory, empirical results show a significantly negative impact of modern gender role attitudes on fertility intentions. When conducting separate analyses for each gender group, this effect vanishes. Controlling for males, subjective precariousness exerts a negative effect, whereas a high amount of fixed-term contracts during professional career exerts a positive effect on fertility intentions. However, females’ fertility intentions are positively affected in a significant manner by a high degree of satisfaction with partnership. Zusammenfassung Während die Einflüsse der Partnerschaftsqualität von sozioökonomischen Faktoren auf die Elternschaftsabsichten junger Erwachsener in Deutschland inzwischen empirisch gut erforscht sind, ist vergleichsweise wenig bekannt über die konkurrierenden Auswirkungen subjektiv verarbeiteter Modernisierungs- und Prekarisierungsfolgen. Basierend auf austauschtheoretischen Ansätzen, führen egalitäre Geschlechterrollenbilder zu einer signifikanten Abschwächung von Elternschaftsabsichten. Dieser Effekt verschwindet sobald nach Geschlechtergruppen getrennte Modelle berechnet werden. Für Männer zeigt sich zudem, dass schwächere subjektive Prekaritätswahrnehmungen mit erhöhten Elternschaftsabsichten einhergehen, während ein hoher Anteil befristeter Beschäftigung im Lebenslauf ebenfalls zur Verstärkung von Elternschaftsintentionen führt. Bei Frauen spielen hingegen weder Prekarisierungs noch Modernisierungseffekte eine Rolle – hier zeitigt lediglich die Partnerschaftszufriedenheit einen signifikant positiven Effekt auf Elternschaftsabsichten.

description: Bilateral control, a remote-control technique, is used to work at a distance. However, many existing bilateral control systems have two common problems: 1) it is difficult to create a system like a human hand, that has multiple degrees of freedom and 2) if the mechanism becomes too complicated, operators feel restrained and experience discomfort. Because, for these reasons, the bilateral control of fingers has not been accomplished to date, we aimed to overcome this by applying functional electrical stimulation~(FES). In our experiments, through an adhesive electrode pad, electrical stimulation was delivered to the muscles that flex and expand the metacarpophalangeal joints of the thumb and middle finger. Position-symmetrical bilateral control was implemented so that the deviation of the master's and slave's positions relative to each other was zero degrees. A sliding mode controller was used as a position controller. We found it possible to control multiple degrees of freedom; however, we found areas where the number of tracking errors was large. We speculated that the middle finger did not bend, because the arm rotates as the thumb was abduction, therefore the position of the motor point of the middle finger deviates from the position of the pad.

description: This article sketches out the approach of ‘Technologies as Anchors for Societal Conflicts’. TASC is conceived as a heuristic tool to help systematically bring into focus societal conflicts and debates that became anchored to technologies without being directly connected to them. This paper’s main hypothesis is that these anchors were developed, deliberately or unintentionally, to make complex issues seem more tangible and easier to resolve. Technological anchors, therefore, could function as a catalyst for a dispute or even turn into a connecting hub between various societal conflicts and debates. TASC is intended to help identify technologies utilised in this way as an object of research that is of interest for a cultural history of technology. To sketch out the utility of TASC and place it within the existing spectrum of methods and concepts applied by historians of technology, debates anchored to the bicycle, electricity generation, the machines of the early Industrial Revolution and nuclear power plants are discussed as examples.

TASC ist als heuristisches Instrument konzipiert, das helfen soll, systematisch gesellschaftliche Konflikte und Debatten in den Fokus zu rücken, die an Technologien verankert wurden, ohne direkt mit ihnen verbunden zu sein. Solche Verankerungen entstanden, so die These dieses Beitrags, gewollt oder ungewollt, um komplexe Probleme greifbarer und leichter lösbar erscheinen zu lassen. Technologische Anker konnten als Katalysator für einen Konflikt fungieren oder sogar zu einem Verbindungspunkt zwischen verschiedenen gesellschaftlichen Konflikten und Debatten werden. TASC soll helfen, solcherart genutzte Technologien als Forschungsgegenstand zu identifizieren, der für eine Kulturgeschichte der Technik von Interesse ist. Um den Nutzen von TASC zu skizzieren und es in das bestehende Spektrum technikhistorischer Methoden und Konzepte einzuordnen, werden exemplarisch Debatten um das Fahrrad, die Stromerzeugung, die Maschinen der frühen Industriellen Revolution und Kernkraftwerke diskutiert.

description: We generalize the standard Penna bit-string model of biological ageing by assuming that each deleterious mutation diminishes the survival probability in every time interval by a small percentage. This effect is added to the usual lethal but age-dependent effect of the same mutation. We then find strong advantages or disadvantages of sexual reproduction (with males and females) compared to asexual cloning, depending on parameters.

Polyhomogeneity and zero-rest-mass fields with applications to Newman-Penrose constants

description: A discussion of polyhomogeneity (asymptotic expansions in terms of $1/r$ and $\ln r$) for zero-rest-mass fields and gravity and its relation with the Newman-Penrose (NP) constants is given. It is shown that for spin-$s$ zero-rest-mass fields propagating on Minkowski spacetime, the logarithmic terms in the asymptotic expansion appear naturally if the field does not obey the ``Peeling theorem''. The terms that give rise to the slower fall-off admit a natural interpretation in terms of advanced field. The connection between such fields and the NP constants is also discussed. The case when the background spacetime is curved and polyhomogeneous (in general) is considered. The free fields have to be polyhomogeneous, but the logarithmic terms due to the connection appear at higher powers of $1/r$. In the case of gravity, it is shown that it is possible to define a new auxiliary field, regular at null infinity, and containing some relevant information on the asymptotic behaviour of the spacetime. This auxiliary zero-rest-mass field ``evaluated at future infinity ($i^+$)'' yields the logarithmic NP constants.

Vacuum Polarization and Energy Conditions at a Planar Frequency Dependent Dielectric to Vacuum Interface

description: The form of the vacuum stress-tensor for the quantized scalar field at a dielectric to vacuum interface is studied. The dielectric is modeled to have an index of refraction that varies with frequency. We find that the stress-tensor components, derived from the mode function expansion of the Wightman function, are naturally regularized by the reflection and transmission coefficients of the mode at the boundary. Additionally, the divergence of the vacuum energy associated with a perfectly reflecting mirror is found to disappear for the dielectric mirror at the expense of introducing a new energy density near the surface which has the opposite sign. Thus the weak energy condition is always violated in some region of the spacetime. For the dielectric mirror, the mean vacuum energy density per unit plate area in a constant time hypersurface is always found to be positive (or zero) and the averaged weak energy condition is proven to hold for all observers with non-zero velocity along the normal direction to the boundary. Both results are found to be generic features of the vacuum stress-tensor and not necessarily dependent of the frequency dependence of the dielectric.

description: Supercapacitors capable of providing high voltage, energy and power density but yet light, low volume occupying, flexible and mechanically robust are highly interesting and demanded for portable applications. Herein, freestanding flexible hybrid electrodes based on MnO2 nanoparticles grown on macroscopic carbon nanotube fibers (CNTf-MnO2) were fabricated, without the need of any metallic current collector. The CNTf, a support with excellent electrical conductivity, mechanical stability, and appropriate pore structure, was homogeneously decorated with porous akhtenskite ε-MnO2 nanoparticles produced via electrodeposition in an optimized organic-aqueous mixture. Electrochemical properties of these decorated fibers were evaluated in different electrolytes including a neutral aqueous solution and a pure 1-butyl-3-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid (PYR14TFSI). This comparison helps discriminate the various contributions to the total capacitance: (surface) Faradaic and non-Faradaic processes, improved wetting by aqueous electrolytes. Accordingly, symmetric supercapacitors with PYR14TFSI led to a high specific energy of 36 Whkg_(MnO_2)^(-1) (16 Whkg-1 including the weight of CNTf) and real specific power of 17 kWkg_(MnO_2)^(-1) (7.5 kWkg-1) at 3.0 V with excellent cycling stability. Moreover, flexible all solid-state supercapacitors were fabricated using PYR14TFSI-based polymer electrolyte, exhibiting maximum energy density of 21 Whkg-1 and maximum power density of 8 kWkg-1 normalized by total active material.

On being a social scientist between institutional demands and day-to-day endeavours. An ethnography at a Cuban university
Creators: name: Cordovés, Alexander
Publisher: name: Zenodo
Year: 2024

description: In this paper, I analyse how university teachers, managers and students in a Cuban university engage with science and innovation targets in their daily work.  These university actors are working in a hierarchical and authoritative environment.  The Ministry of Education sets targets for academic performance in terms of getting involved in research projects and publishing scientific articles, which seem to be aligned with the World University Rankings.   Managers turn these targets into assessment indicators and use them to systematically evaluate academics through a yearly teacher appraisal. The study is based on fieldwork conducted at the Faculty of Social Science, University of Holguin in Cuba, and explored how academics, students and managers interpreted, contested, planned and accomplished these targets in their everyday science and innovation activities. Using the anthropology of policy approach (Shore and Wright 1997), I show how, despite the challenges of getting funded, the high standards they are calling upon to meet, and the day-to-day barriers they must face, teachers get published, are involved in research projects, and organise or attend scientific events, even though those outcomes do not fit the expected metrics.

description: We have used Monte Carlo simulation techniques to obtain the magnetic phase diagram of the double exchange Hamiltonian. We have found that the Berry's phase of the hopping amplitude has a negligible effect in the value of the magnetic critical temperature. To avoid finite size problems in our simulations we have also developed an approximated expression for the double exchange energy. This allows us to obtain the critical temperature for the ferromagnetic to paramagnetic transition more accurately. In our calculations we do not observe any strange behavior in the kinetic energy, chemical potential or electron density of states near the magnetic critical temperature. Therefore, we conclude that other effects, not included in the double exchange Hamiltonian, are needed to understand the metal-insulator transition which occurs in the manganites.

The influence of the oscillations of the chemical potential on the de Haas - van Alphen effect in quasi-two-dimensional compounds

description: The de Haas - van Alphen effect in quasi-two-dimensional metals is studied at arbitrary parameters. The oscillations of the chemical potential may substantially change the temperature dependence of harmonic amplitudes that is usually used to determine the effective electron mass. Hence, the processing of the experimental data using the standard Lifshitz-Kosevich formula (that assumes the chemical potential to be constant) may lead to substantial errors even in the limit of strong harmonic damping. This fact may explain the difference between the effective electron masses, determined from the de Haas - van Alphen effect and the cyclotron resonance measurements. The oscillations of the chemical potential and the deviations from the Lifshitz-Kosevich formula depend on the reservoir density of states, that exists in organic metals due to open sheets of Fermi surface. This dependence can be used to determine the density of electron states on open sheets of Fermi surface. We present the analytical results of the calculations of harmonic amplitudes in some limiting cases that show the importance of the oscillations of the chemical potential. The algorithm of the simple numerical calculation of the harmonic amplitudes at arbitrary reservoir density of states, arbitrary warping, spin-splitting, temperature and Dingle temperature is also described.

description: The absence of large-angle correlations in the map of cosmic microwave background temperature fluctuations is among the well-established anomalies identified in full-sky and cut-sky maps over the past three decades. Suppressed large-angle correlations are rare statistical flukes in standard inflationary cosmological models. One natural explanation could be that the underlying primordial density perturbations lack correlations on large distance scales. To test this idea, we replace Fourier modes by a wavelet basis with compact spatial support. While the angular correlation function of perturbations can readily be suppressed, the observed monopole and dipole-subtracted correlation function is not generally suppressed. This suggests that suppression of large-angle temperature correlations requires a mechanism that has both real-space and harmonic-space effects.

description: We study the phase diagram of R_{1-x}A_xMnO_3 (R=La, Pr, Nd, Sm ; A=Ca, Sr, Ba) by taking into account the degeneracy of $e_g$ orbitals and the anisotropy of the transfer integral. The electron-electron interaction is treated in the mean field approximation with the optimization of the spin and orbital structures. The global phase diagram is understood in terms of the two interactions, i.e., the super exchange interaction for small $x$ and the double exchange interaction for larger $x$ modified by the orbital degeneracy. The dimensionality of the electronic energy band resulting from the orbital structure is essential to determine the phase diagram. The effects of the Jahn-Teller distortion are also studied.

description: Alfvén vortex is a multi-scale nonlinear structure which contributes to intermittency of turbulence. Despite previous explorations mostly on the spatial properties of the Alfvén vortex (i.e., scale, orientation, and motion), the plasma characteristics within the Alfvén vortex are unknown. Moreover, the connection between the plasma energization and the Alfvén vortex still remains unclear. Based on high resolution in-situ measurement from the Magnetospheric Multiscale (MMS) mission, we report for the first time, distinctive plasma features within an Alfvén vortex. This Alfvén vortex is identified to be two-dimensional ($k_{\bot} \gg k_{\|}$) quasi-monopole with a radius of ~10 proton gyroscales. Its magnetic fluctuations $δB_{\bot}$ are anti correlated with velocity fluctuations $δV_{\bot}$, thus the parallel current density $j_{\|}$ and flow vorticity $ω_{\|}$ are anti-aligned. In different part of the vortex (i.e., edge, middle, center), the ion and electron temperatures are found to be quite different and they behave in the reverse trend: the ion temperature variations are correlated with $j_{\|}$, while the electron temperature variations are correlated with $ω_{\|}$. Furthermore, the temperature anisotropies, together with the non-Maxwellian kinetic effects, exhibit strong enhancement at peaks of $|ω_{\|}| (|j_{\|}|)$ within the vortex. Comparison between observations and numerical/theoretical results are made. In addition, the energy-conversion channels and the compressibility associated with the Alfvén vortex are discussed. These results may help to understand the link between coherent vortex structures and the kinetic processes, which determines how turbulence energy dissipate in the weakly-collisional space plasmas.

description: Employers are constantly seeking to improve employee performance by means of investing in employee training. The results of training are to a large extent dependent on employees’ willingness to behave productively in a cooperative manner. Yet, systematic evidence investigating the causal relation between training and employees’ cooperative behavior is rare. Here we present results from a contextualized laboratory experiment in which subjects, who differ in terms of training participation, were asked to contribute resources to a team effort. We conclude that training promotes cooperative behavior, i.e. voluntary contributions made to the team effort, in teams of employees working together for short periods of time. Training enhances cooperative behavior the most when provided to the higher skilled subjects. We also find that members in more stable teams act very cooperatively under all conditions, but their contributions do not increase further with training.

description: Hybridisation is a powerful strategy towards the next generation of multifunctional materials for environmental and sustainable energy applications. Here, we report a new inorganic nanocarbon hybrid material prepared with atomically controlled deposition of a monocrystalline TiO2 layer that conformally coats a macroscopic carbon nanotube (CNT) fiber. Through X-ray diffraction, Raman spectroscopy and photoemission spectroscopy we detect the formation of a covalent Ti-O-C bond at the TiO2/CNT interface and a residual strain of approximately 0.7-2 \%, which is tensile in TiO2 and compressive in the CNT. It arises after deposition of the amorphous oxide onto the CNT surface previously functionalized by the oxygen plasma used in ALD. These features are observed in samples of different TiO2 thickness, in the range from 10 to 80 nm. Ultraviolet photoemission spectroscopy on a 20 nm-thick TiO2 coated sample gives a work function of 4.27 eV, between that of TiO2 (4.23 eV) and the CNT fiber (4.41 eV), and the presence of new interband gap states that shift the valence band maximum to 1.05 eV below the Fermi level. Photoelectrochemical measurements demonstrate electron transfer from TiO2 to the CNT fiber network under UV irradiation. Electrochemical impedance spectroscopy measurements reveal a low resistance for charge transfer and transport, as well as a large capacitance. Our results point to the fact that these hybrids, in which each phase has nanometric thickness and the current collector is integrated into the material, are very different from conventional electrodes and can provide a number of superior properties.
Greek Lesbian Teachers: School, Nation, Family

description: This database is compiled as part of my research project on lesbian teachers in Greece, culminating in my PhD dissertation under the title “Greek Lesbian Teachers: School, Nation, Family”. The research project explores how Greek lesbian teachers construct their subjectivities and negotiate their sexuality in relation to the social contexts in which they are situated. In looking for answer to the main research question, I employed the qualitative method of semi-structured interviews. Since there was no previous research on Greek lesbian teachers, this semi-structured design allowed me to focus on particular issues surrounding the women and their teaching roles, whilst simultaneously allowing space for free interaction and spontaneity. During the interviews I had a basic interview guide with ten fundamental written questions. Interview data was collected from semi-structured interviews with seventeen women who self-identify as lesbians. All of the participants are white, and were born in Greece. At the time of the interviews, one of them lived in Thessaloniki, one of them lived on Crete, and the rest lived in Athens. Four of the participants work at kindergartens, eight at primary schools, two at secondary schools, and three at high schools. Thus, in this study, all levels of teaching up to high school level are represented. The ages of the participants range from 29 to 58 years old. With the exception of one teacher who works at a private school, the remainder work within the state education system. The teachers are predominantly highly experienced classroom teachers, their teaching experience ranging from 6 to 30 years. With the exception of three women who are substitute teachers, all are in tenured, full-time teaching positions. All interviews were transcribed verbatim. During the analysis, I experimented with different coding categories and emerging themes. Several key ideas and recurring themes were identified under each of the ten questions I had prepared. These themes were used to construct the framework of the three chapters presented in my dissertation.

description: We report on our numerical implementation of fully relativistic hydrodynamics coupled to Einstein's field equations in three spatial dimensions. We briefly review several steps in our code development, including our recasting of Einstein's equations and several tests which demonstrate its advantages for numerical integrations. We outline our implementation of relativistic hydrodynamics, and present numerical results for the evolution of both stable and unstable Oppenheimer-Volkov equilibrium stars, which represent a very promising first test of our code.

description: Certain inflation models undergo pre-heating, in which inflaton oscillations can drive parametric resonance instabilities. We discuss several phenomena stemming from such instabilities, especially in weak-scale models; generically, these involve energizing a resonant system so that it can evade tunneling by crossing barriers classically. One possibility is a spontaneous change of phase from a lower-energy vacuum state to one of higher energy, as exemplified by an asymmetric double-well potential with different masses in each well. If the lower well is in resonance with oscillations of the potential, a system can be driven resonantly to the upper well and stay there (except for tunneling) if the upper well is not resonant. Another example occurs in hybrid inflation models where the Higgs field is resonant; the Higgs oscillations can be transferred to electroweak (EW) gauge potentials, leading to rapid transitions over sphaleron barriers and consequent B+L violation. Given an appropriate CP-violating seed, we find that preheating can drive a time-varying condensate of Chern-Simons number over large spatial scales; this condensate evolves by oscillation as well as decay into modes with shorter spatial gradients, eventually ending up as a condensate of sphalerons. We study these examples numerically and to some extent analytically. The emphasis in the present paper is on the generic mechanisms, and not on specific preheating models; these will be discussed in a later paper.

description: The generalization properties of an attractive network of non monotonic neurons which infers concepts from samples are studied. The macroscopic dynamics for the overlap between the state of the neurons with the concepts, well as the activity of the neurons, are obtained and searched for through its numerical behavior. Complex behavior leading from fixed points to chaos through a cascade of bifurcation are found, when we increase the correlation between samples or decrease the activity of the samples and the load of concepts, or tune the threshold of fatigue of the neurons. Both the information dimension and the Liapunov exponent are given, and a phase diagram is built.
