description: The civic mission of schools in nurturing political literature, critical thinking and participatory citizens has always been played down in Hong Kong schools. On one hand, teaching civic education has never been ranked high in the education agenda. On the other hand, because of the conservative nature of schools, students are rarely encouraged to participate in school governance for the enhancement of their citizenship development. Funded by the General Research Fund (GRF) in Hong Kong, the authors conducted a quantitative survey on students’ participation in school governance and their citizenship development in 2013 to explore 1) students’ conception of “good citizens”; 2) the level and scope of student participation in school governance; and 3) the facilitating and hindering factors influencing student participation. This paper is a report on the simple statistical results of the survey findings. With reference to Westheimer and Kahne’s typologies, the findings revealed that the students had an eclectic understanding of citizenship, with higher scores for Personally Responsible Citizen and lower scores for Participatory, Justice Oriented and Patriotic Citizen, reflecting a conservative orientation. Concerning the implementation of school civic mission through student participation in school governance, it was found that students were rarely allowed to engage in important school matters, such as formulation of school rules and discussion of the school development plan. Our findings also revealed that schools were more inclined to inform students and consult them rather than confer real participation and powers to them. The paper concludes that the current practice of student participation in school governance does not facilitate the nurturing of active participatory citizens, particularly of a Justice Oriented nature, and this is urgently needed for the democratic development of Hong Kong.

description: We study finite-volume effects on the masses of the ground-state octet baryons using covariant baryon chiral perturbation theory (ChPT) up to next-to-leading order by analyzing the latest $n_f=2+1$ lattice Quantum ChromoDynamics (LQCD) results from the NPLQCD collaboration. Contributions of virtual decuplet baryons are taken into account using the "consistent" coupling scheme. We compare our results with those obtained from heavy baryon ChPT and show that, although both approaches can describe well the lattice data, the underlying physics is different: In HBChPT, virtual decuplet baryons play a more important role than they do in covariant ChPT. This is because the virtual octet baryon contributions to finite-volume corrections are larger in covariant ChPT than in HBChPT, while the contributions of intermediate decuplet baryons are smaller, because of relativistic effects. We observe that for the octet baryon masses, at fixed $m_πL$ ($\gg1$) finite-volume corrections decrease as $m_π$ approaches its physical value, provided that the strange quark mass is at or close to its physical value, as in most LQCD setups.

Political Participation as Public Pedagogy – The Educational Situation in Young People’s Political Conversations in Social Media
Creators: name: Andersson, Erik
name: Olson, Maria
Publisher: name: sowi-online e.V., Bielefeld
Year: 2014

description: In this article we argue that young people’s political participation in the social media can be considered ‘public pedagogy’. The argument builds on a previous empirical analysis of a Swedish net community called Black Heart. Theoretically, the article is based on a particular notion of public pedagogy, education and Hannah Arendt’s expressive agonism. The political participation that takes place in the net community builds up an educational situation that involves central characteristics: communication, community building, a strong content focus and content production, argumentation and rule following. These characteristics pave the way for young people’s public voicing, experiencing, preferences and political interests that guide their everyday political life and learning – a phenomenon that we understand as a form of public pedagogy.

The dual geometries with zero and nonzero current quark masses are obtained numerically. We discuss meson spectra and binding energy of heavy quarkonium with the subleading corrections in the hard wall model.

description: In order to investigate the effects of temperature and pressure on the size of asphaltene particles, a novel series of pressure and temperature cells were constructed and integrated with a Brinkmann Particle Size Analyzer. Four separate oils, from an asphaltic condensate to a heavy crude oil were examined using n-pentane and nheptane as diluents. Atmospheric pressure investigations with n-heptane as the diluent over the temperature range of 0°C to 50°C showed no change in particle size, but did reveal bimodal distributions. The effect of temperature from 0°C to 100°C and pressure from 2.2 MPa to 5. 6 MPa were successfully explored. Increasing the pressure induced a small change in the mean size of the particles, except for the Lindberg oil particles for which the mean size decreased slightly. A variation of the temperature from 0°C to 100°C showed little effect on asphaltene particle size, except upon the Border condensate. The heavier molecular weight oils from Cold Lake and Lindberg, Alberta formed 11 super agglomerates II or macro-agglomerates at 75 ° C and higher. The Border condensate and Countess oil both displayed instances when a bimodal size distribution was apparent. Most of the runs showed some suggestion of another distribution in addition to the main particle size distribution.

description: Introduction A surgical audit study among Batu Pahat population was conducted in determining the commonest position of appendix in post appendectomy. Methodology: This is a retrospective study. A total of 204 cases of patients underwent an appendectomy admitted to the surgical ward from January 2017 until January 2018 at Hospital Sultanah Nora Ismail (HSNI) were audited retrospectively. Results: This findings showed different figures of ascendancy in gender among patients who underwent an appendectomy with females 58.8% and males 41.2%. The perforation rate was 40.7% and delay in diagnosis was found to be 19.1%. The perforated appendix had a significantly higher incidence in males with a correlation of p-value 0.04. Retrocaecal appendix (RA) remained the commonest position for patients who underwent an appendectomy with 26.9%. RA is associated with an increased incidence of perforation (p-value 0.01). Conclusion The position of appendix in our patients who underwent an appendectomy is parallel to the reports available globally in that it is retrocaecal followed by retroileal as the commonest position among residence of Batu Pahat.

description: Radio relics have been discovered in many galaxy clusters. They are believed to trace shock fronts induced by cluster mergers. Cosmological simulations allow us to study merger shocks in detail since the intra-cluster medium is heated by shock dissipation. Using high resolution cosmological simulations, identifying shock fronts and applying a parametric model for the radio emission allows us to simulate the formation of radio relics. We analyze a simulated shock front in detail. We find a rather broad Mach number distribution. The Mach number affects strongly the number density of relativistic electrons in the downstream area, hence, the radio luminosity varies significantly across the shock surface. The abundance of radio relics can be modeled with the help of the radio power probability distribution which aims at predicting radio relic number counts. Since the actual electron acceleration efficiency is not known, predictions for the number counts need to be normalized by the observed number of radio relics. For the characteristics of upcoming low frequency surveys we find that about thousand relics are awaiting discovery.

description: The investigation is about which ideas ninth form students at grammar schools and secondary modern schools have about globalisation. It shall be investigated if the perception of and judgement on globalisation-connected contexts happens along social structure-specific patterns. At first, by way of a questionnaire, the field of ideas is supposed to be broadly recorded, a selection of interview partners based on the results of the questionnaire aims at a deeper analysis of the students´ ideas. Knowledge of these subjective preconditions for learning, as far as the topic of globalisation is concerned, is supposed to provide empirically-grounded hints for what curricula in the political-economic field of learning might look like. Apart from the education-political background, also the methodical outline of the investigation is described. This is followed by a presentation of the results of the analysis of the questionnaire.

Using quantum correlations with an ancilla qubit, DCQD reduces exponentially the number of experimental configurations required for standard QPT. With this technique, the system's relaxation times T1 and T2 were measured with a single experimental configuration. We further show the first complete characterization of single-qubit processes using a single generalized measurement realized through multi-body correlations with three ancilla qubits.

title: Psychological and physiological responses to sounds from neighbours in wood residential buildings
Creators: name: Frescura, Alessia
Publisher: name: University of Liverpool Repository
Year: 2022

description: Sound from neighbours is a key locus of contestation in densifying cities, where the construction of high-rise lightweight buildings is promoted as more sustainable for the environment. Neighbours’ sounds invade private spaces and impair their restorative potential, sometimes reducing dramatically the quality of life in homes. However, there have been little investigations on responses to neighbours sounds compared to environmental sound sources such as traffic, or occupational sounds in workplaces. This thesis work gathers five laboratory-based experiments, aiming at understanding the psychological, affective, and physiological responses to sounds from neighbours in wood residential buildings. The main objective was to deepen the understanding of how impact footsteps sound affects residents. Additionally, airborne sounds such as speech and music were investigated as a part of the dissertation. There were four main questions at the basis of the whole research. Firstly, the correlations between standardised and real sound sources impacting wood floor structures were investigated, clarifying the role of the type of sound source in the existing mismatch between subjective and objective evaluation of lightweight floors. Secondly, the focus shifted towards the responses to the combination of impact and airborne sounds. Significant differences in annoyance responses were observed for sounds heard singularly or in combination, highlighting the need for a holistic building acoustic regulations which keep into account the simultaneous presence of several neighbours sound sources at once, as a usual condition in residential settings. Eventually, third and fourth questions looked at how humans respond to sounds from neighbours psychologically, emotionally, and physiologically, and at which acoustic and non-acoustic factors affect the responses. The affective dimensions of arousal and valence aligned along the defensive motivation circuit, which mediates the reaction to threat. Significant changes from baseline were observed in all the peripheral physiological parameters and in the EEG Alpha waves, during exposure to neighbours sounds through lightweight wood floor structures and partition walls. According to the findings, spatial characteristics, sound pressure levels, type of sound source, the pace of upstairs footsteps, and time of the day significantly influenced perceived annoyance. Additionally, responses to neighbours’ sounds were found to be significantly different across participants with different sensitivity to noise, different attitudes towards their neighbours, and dissimilar circadian rhythm types.

Economic Citizenship and Socio-Economic Rationality as Foundations of an Appropriate Economic Education
Creators: name: Schank, Christoph
name: Lorch, Alexander
Publisher: name: sowi-online e.V., Bielefeld
Year: 2014

description: In this article we argue that social science education needs to convey more than operational mechanisms of society. Especially in socio-economic education, questions of business ethics, i.e. phenomena of economics and society need to be integrated and reflected, decidedly focusing on the moral content of economics. With the introduction of economic citizenship as the ideal economic actor to be the purpose of economic education, this paper proposes that economic education needs to connect economic expertise and moral judgment and should also allude to the necessity of every market action’s conditional legitimization by society.

We propose to discuss different ‘sites’ of morality as a heuristic approach to the different areas of economic responsibility. The individual, organizational and political level of responsibility helps to categorize the different moral issues of economic activity and serves as a great pattern to explain economic relations to scholars and students.

description: The theoretical basis of the phenomenon of effective and exact dimensional reduction, or holographic correspondence, is investigated in a wide variety of physical systems. We first derive general inequalities linking quantum systems of different spatial (or spatio-temporal) dimensionality, thus establishing bounds on arbitrary correlation functions. These bounds enforce an {\em effective} dimensional reduction and become most potent in the presence of certain symmetries. {\em Exact} dimensional reduction can stem from a duality that (i) follows from properties of the local density of states, and/or (ii) from properties of Hamiltonian-dependent algebras of interactions. Dualities of the first type (i) are illustrated with large-$n$ vector theories whose local density of states may remain invariant under transformations that change the dimension. We argue that a broad class of examples of dimensional reduction may be understood in terms of the functional dependence of observables on the local density of states. Dualities of the second type (ii) are obtained via {\em bond algebras}, a recently developed algebraic tool. We apply this technique to systems displaying topological quantum order, and also discuss the implications of dimensional reduction for the storage of quantum information.

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: This paper deals with multi-user detection techniques in asynchronous multibeam satellite communications. The proposed solutions are based on successive interference cancellation architecture (SIC) and channel decoding algorithms. The aim of these detection methods is to reduce the effect of cochannel interference due to co-frequency access, and consequently, improves the capacity of the mulitbeam communications systems, by improving frequency reuse. Channel estimation allows the determination of interference coefficients, which helps their effects compensation. The developed multiuser detections techniques are iterative. Therefore, detection quality is improved from a stage to another. Moreover, a signals combining method, which is integrated into these detection solutions, enhances their capability. The proposed solutions are evaluated through computer simulations, where an asynchronous multibeam satellite link is considered over an AWGN channel. The obtained simulation results showed the robustness of these multi-user detection techniques.

Encouraging Classroom Discussion
Creators: name: McKee, Robert Joseph
Publisher: name: sowi-online e.V., Bielefeld
Year: 2014

description: Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

description: Context: IGRJ11014-6103 is one of the still unidentified hard X-ray INTEGRAL sources, reported for the first time in the 4th IBIS/ISGRI catalog. Aims: We investigated the nature of IGR J11014-6103 by carrying out a multiwavelength analysis of the available archival observations performed in the direction of the source. Methods: We present first the results of the timing and spectral analysis of all the X-ray observations of IGR J11014-6103 carried out with ROSAT, ASCA, Einstein, Swift, and XMM-Newton, and then use them to search for possible counterparts to the source in the optical, infra-red, radio and gamma-ray domain. Results: Our analysis revealed that IGR J11014-6103 is comprised of three different X-ray emitting regions: a point-like source, an extended object and a cometary-like "tail" (~4 arcmin). A possible radio counterpart positionally coincident with the source was also identified. Conclusions: Based on these results, we suggest that the emission from IGR J11014-6103 is generated by a pulsar wind nebula produced by a high-velocity pulsar. IGR J11014-6103 might be the first of these systems detected with INTEGRAL IBIS/ISGRI.

description: We propose a new model suitable for a nonequilibrium molecular dynamics (MD) simulation of electrical conductors. The model consists of classical electrons and atoms. The atoms compose a lattice vibration system. The electrons are scattered by electron-electron and electron-atom interactions. Since the scattering cross section is physically more important than the functional form of a scattering potential, we propose to devise the electron-atom interaction potential in such a way that its scattering cross section agrees with that of quantum-mechanical one. To demonstrate advantages of the proposed model, we perform a nonequilibrium MD simulation assuming a doped semiconductor at room or higher temperature. In the linear response regime, we confirm Ohm's law, the dispersion relations and the fluctuation-dissipation relation. Furthermore, we obtain reasonable dependence of the electrical conductivity on temperature, despite the fact that our model is a classical model.

description: Skeletochronology was used to determine the ages of 30 loggerhead sea turtles (Caretta caretta) found in French Mediterranean waters. Histological sections were performed with 30 humeri collected on stranded C. caretta on the coast of Provence and the Gulf of Lion. Lines of arrested growth (LAGs) were used to evaluate age, considering only one period of arrested growth per year. Two successive LAGs delimit an interval that is proportional to the individual’s body growth. In a first step, we created a skeletogram for each individual that identified its LAGs. Secondly, we measured the areas delineating successive intervals to determine individual growth patterns over the years. Two methods were used to deduce sea turtle age from histological sections: the correction factor (CF) method and the growth rate (GR) method, the latter using Von Bertalanffy growth function. Age estimations varied from 4.3 to 24.7 years (mean ± SD = 10.1 ± 4.8) with the CF method and from 6.2 to 25.6 years (mean ± SD = 12.2 ± 5.2) with the GR method, with no significant difference between the methods. The study sample was thus mostly composed of juveniles, which is also the most frequent life stage observed in the study area. The annual curved carapace length growth rate calculated with every LAG interval varied from 1.0 to 6.9 cm/year (mean ± SD = 3.5 ± 1.4, n = 115). High variability in interindividual growth rates were observed, which is of interest in understanding the complex lifecycle of these long-lived marine reptiles.

description: This comment addresses several issues in the paper by Sepioni et al., where it is stated that the ferromagnetism in pristine highly oriented pyrolytic graphite (HOPG) reported by several groups in the previous years is most likely due to impurity contamination. In this comment, clear arguments are given why this statement is not justified. Furthermore, it is pointed out, that there are already measurements using element-sensitive microscopic techniques, e.g. X-ray Magnetic Circular Dichroism (XMCD) that directly proved the intrinsic origin of the ferromagnetism in graphite, also in pristine HOPG.

description: The Quaternary Period is characterized by dramatic global climatic changes. Quaternary fossil deposits, which can offer excellent stratigraphic resolution, provide a unique opportunity to understand how fauna respond to past environmental change. Here, we test if the herpetofauna of McEachern’s Deathtrap Cave, a late Pleistocene to Holocene pitfall trap deposit from Victoria, Australia, shows climate-related shifts in taxonomic relative abundance through time. During the last 14,000 years, southeastern Australia experienced pronounced periods of aridity, while temperatures remained relatively stable. We show that the stratigraphic layers of this deposit are characterized by different relative abundances of reptile subfamilies, and that changes in subfamily abundance between layers correlate with known shifts to aridity, based on the percentage of C4 grasses present in the region. We further identify 13 lizard morphotypes from the fossil deposit and compare this diversity with the present-day lizard fauna. Our analyses indicate that gradual changes in community structure, which are typically observed in southeastern Australian vertebrate communities during the Pleistocene–Holocene transition, can partly be explained by changing aridity. These findings represent an important contribution to understanding Quaternary community change in Australia, particularly because evidence of faunal succession of reptile and amphibian communities in Victoria is lacking. Our results further demonstrate the utility of the Australian herpetofaunal fossil record for detecting community responses to past climate change on relatively shallow timescales and at higher levels of taxonomic identification.

Normativity in Russian History Education: Political Patterns and National History Textbooks
Creators: name: Potapova, Natalia
Publisher: name: sowi-online e.V., Bielefeld
Year: 2014

description: My current research concerns the politics in Russian History education. In this paper I discuss some of the issues raised by the study of national History textbooks. I analyze the normative implications of sentences and statements about the past and try to define contrary ideological assumptions. How do the authors construct the aim of historical education? In what kind of activities do the typical patterns of textbook questions and instructions try to engage pupils? How do the different Textbooks construct the political subject? The article aims to explore the media construction of political actions in Russian School History Textbooks.

description: Bibliography: p. 100-105.
description: A high-pressure, temperature controlled sapphire cell has been designed and constructed to study the nucleation behaviour of clathrate hydrates under pristine experimental conditions. Light scattering optics and detection equipment have been installed to monitor the incipient hydrate phase development and characterize the early stages of crystal growth. The aspects of light scattering theory that are relevant to the nucleation of clathrate hydrates are outlined and applications of the theory to particle size characterization are described. Preliminary experiments have demonstrated that within the detection limit of the apparatus, the hydrate phase was not present in sufficient size or number prior to a nearly instantaneous appearance of the phase. A series of investigations to identify nucleation process variables have identified a temperature history of the aqueous phase and the efficacy of mechanical or thermal perturbations on inducing hydrate formation. An argument that nucleation is a stochastic process is developed.

Social Science Teachers on Citizenship Education: A Comparative Study of Two Post-Communist Countries
Creators: name: Jeliazkova, Margarita
Publisher: name: sowi-online e.V., Bielefeld
Year: 2014

description: This paper presents some of the results of a comparative study of high school social science teachers in two post-communist European countries: Bulgaria and Croatia. In both countries, citizenship education was implemented as a part of the EU accession efforts. I discuss the ways teachers deal with the everyday dilemmas of teaching in a field which is by definition controversial and loaded with diverse political meanings. The study involved teachers in the two countries using Q-methodology, a combination of quantitative and qualitative techniques. Five distinct ways of dealing with these questions, five types of views were found in Bulgaria: Pragmatic Conservatives, Deliberative Liberals, Local Social Guardians, Personal Growth Facilitators, and Global Future Debaters. In Croatia, the types of views were: Patriotic Conservatives, Liberal Democracy Mentors, Reflective Humanists, and Personal Growth Coaches. The differences and similarities between the teachers’ views in both countries are compared. The study highlights the crucial role of teachers, of their beliefs and experiences in shaping national and European citizenship education policies. The implications of the study findings for citizenship education policy, curriculum development, and teacher training are briefly discussed.

description: Known from dozens of specimens discovered since the early 20th century, Gorgosaurus libratus has arguably contributed more than any other taxon to our understanding of the life history of tyrannosaurids. However, juvenile material for this taxon is rare. Here, we describe two small, articulated Gorgosaurus specimens (skull lengths of ca. 500 mm) that help advance our knowledge of the anatomy and ontogeny of this taxon and of tyrannosaurids in general. The new specimens exhibit hallmark juvenile tyrannosaurid features, including long, low, and narrow skulls, large circular orbits, absent or incipient cranial ornamentation, ziphodont dentition, and an overall gracile skull frame. Comparison with other Gorgosaurus specimens of various ontogenetic stages allows for an examination of the timing of morphological changes that occurred through ontogeny in this taxon relative to other tyrannosaurids. Of particular note, Gorgosaurus and the larger Tyrannosaurus rex are found to have experienced similar ontogenetic transformations at similar percent skull length relative to the large known individuals for each respective taxon but at different absolute body sizes and biological ages, occurring at a larger size and older age in Tyrannosaurus than in Gorgosaurus. These results suggest a dissociation between the timing of cranial development and body size in tyrannosaurids. Finally, the recognition of ontogenetically invariant characters in Gorgosaurus makes it possible to determine the taxonomic identity of previously misidentified specimens.

description: A set of algebraic numbers has the Northcott property if each of its subsets of bounded Weil height is finite. Northcott's Theorem, which has many Diophantine applications, states that sets of bounded degree have the Northcott property. Bombieri, Dvornicich and Zannier raised the problem of finding fields of infinite degree with this property. Bombieri and Zannier have shown that $\IQ_{ab}^{(d)}$, the maximal abelian subfield of the field generated by all algebraic numbers of degree at most $d$, is such a field. In this note we give a simple criterion for the Northcott property and, as an application, we deduce several new examples, e.g. $\IQ(2^{1/d_1},3^{1/d_2},5^{1/d_3},7^{1/d_4},11^{1/d_5},...)$ has the Northcott property if and only if $2^{1/d_1},3^{1/d_2},5^{1/d_3},7^{1/d_4},11^{1/d_5},...$ tends to infinity.

What does Political Participation Mean to Spanish Students?
Creators: name: Sant, Edda
Publisher: name: sowi-online e.V., Bielefeld
Year: 2015

description: This article explores how a group of Spanish students (aged 11–19) understand the meaning of ‘political participation’ in society and discusses the implications of their views for debates and practices in citizenship education. The ways in which these students (n=112) describe and interpret political participation are analysed using an in-depth and interpretative approach employing open questionnaires and interviews. The results suggest that most students value political participation in positive terms and that ‘activist’ students have a more optimistic view of the effectiveness of participation and especially of new forms of participation such as protests.
