description: The simplest continuum model of a one-dimensional non-interacting superconducting fermionic symmetry-protected topological (SPT) phase is studied in great detail using analytical methods. In a first step, we present a full exact diagonalization of the fermionic Bogoliubov-de Gennes Hamiltonian for a system of finite length and with open boundaries. In particular, we derive exact analytical expressions for the Majorana zero modes emerging in the topologically non-trivial phase, revealing their spatial localization, their transformation properties under symmetry operations, and the exact finite-size energy splitting of the associated quasi-degenerate ground states. We then proceed to analyze the model via exact operator bosonization in both open and closed geometries. In the closed wire geometry, we demonstrate fermion parity switching from twisting boundary conditions in the topologically non-trivial phase. For the open wire, on the other hand, we first take a semiclassical approach employing the Mathieu equation to study the two quasi-degenerate ground states as well as their energy splitting at finite system sizes. We then finally derive the exact forms of the Majorana zero modes in the bosonic language using vertex-algebra techniques. These modes are verified to be in exact agreement with the results obtained from the fermionic description. The complementary viewpoints provided by the fermionic and bosonic formulations of the superconducting SPT phase are reconciled, allowing us to provide a complete and exact account of how Majorana zero modes manifest in a bosonized description of an SPT phase.

description: We present results of our intermediate-band optical imaging survey for high-$z$ Ly$α$ emitters (LAEs) using the prime focus camera, Suprime-Cam, on the 8.2m Subaru Telescope. In our survey, we use eleven filters; four broad-band filters ($B$, $R_{\rm c}$, $i^\prime$, and $z^\prime$) and seven intermediate-band filters covering from 500 nm to 720 nm; we call this imaging program as the Mahoroba-11. The seven intermediate-band filters are selected from the IA filter series that is the Suprime-Cam intermediate-band filter system whose spectral resolution is $R = 23$. Our survey has been made in a $34^\prime \times 27^\prime$ sky area in the Subaru XMM Newton Deep Survey field. We have found 409 IA-excess objects that provide us a large photometric sample of strong emission-line objects. Applying the photometric redshift method to this sample, we obtained a new sample of 198 LAE candidates at $3 < z < 5$. We found that there is no evidence for evolution of the number density and the star formation rate density for LAEs with $\log L({\rm Ly}α) ({\rm erg s^{-1}}) > 42.67$ between $z \sim 3$ and 5.

Multidimensional perfectionism and body image dysfunction in the prediction of eating disorder symptoms
Creators: name: McGee, Brandy Jennifer
Publisher: name: University of British Columbia
Year: 2009

description: The relationship between perfectionism and eating disorders has long been recognized, if not well understood. The current study tested a diathesis-stress model of the associations among multidimensional perfectionism, body image discrepancy, body image investment, and anorexic and bulimic symptoms in 145 female university students. The findings indicated that socially prescribed perfectionism, perfectionistic self-promotion, non display of imperfection, and nondisclosure of imperfection were associated with both anorexic and bulimic symptoms, suggesting that the social facets of perfectionism may be most relevant to eating disorder symptoms. Further, for the self-presentation dimensions these results were qualified by a moderation effect. The results showed that perfectionistic self-presentation predicted both anorexic and bulimic symptoms in women who were dissatisfied with their bodies, but that it did not predict eating problems in women who liked their bodies and felt there was little or no discrepancy between their actual and ideal appearances. Moreover, body image investment did not moderate the relationship between trait and self-presentational perfectionism and eating disorder symptoms. The results are discussed in light of personality and social psychology theory on escape from aversive self-awareness and construction of the social self.
The World after Covid-19. The New Phase of Italian Third Sector Evolution.
Creators: name: Bianchi, Michele

description: Italy has witnessed some of the most tremendous consequences of Covid-19; the society has reacted to the pandemic to survive and recover. The Italian Third Sector (TS) has been constantly on the front line of the emergency putting in place services, initiatives and projects to assist those more in need. This research began with the scope to collect information about the reactions of TS organizations during the pandemic; through interviews with managers, workers and volunteers, the data collection has grasped information about the immediate responses; nevertheless, data has generated broader considerations. Through the Grounded Theory approach, this work proposes the theorization of a new step of TS in its evolution, a further affirmation of the TS as the key player that designs and manages local processes for welfare, civic empowerment and the common good. TS is now ready to lead local processes of welfare claiming for real partnerships with public actors.

description: The intent of this thesis is to present a design of an integrated simulation model for the cooling and air conditioning circuits in a fuel cell electric vehicle. Using the simulation environment Dymola, the coupling of submodels to form the thermal management system has been investigated. On the account of flexible exchange of submodels and the unsteady operational status of the general model, an approach for a co-simulation using the Building Controls Virtual Test Bed (BCVTB) software to couple between submodels is also analyzed, introduced and tested. A comparison is to be finally done between coupling in Dymola and co-simulating in BCVTB based on the simulation speed, flexibility of submodels' exchange, ease of coupling and interface. This thesis contains a good example for modelling and simulating a physical software model for the thermal management system in an electric vehicle from the scratch. It also addresses other attempt to introduce a promising co-simulation tool (BCVTB) developed at LBNL.

description: As a modern approach for the foundation of quantum theory, existing studies of General Probabilistic Theories gave various models of states and measurements that are quite different from quantum theory. In this paper, to seek a more realistic situation, we investigate models approximately close to quantum theory. We define larger measurement classes that are smoothly connected with the class of POVMs via a parameter, and investigate the performance of perfect discrimination. As a result, we give a sufficient condition of perfect discrimination, which shows a significant improvement beyond the class of POVMs.

Year: 2024

description: The rise of visual-based social media platforms such as Instagram, Snapchat, and TikTok has transformed the digital landscape and become increasingly important for young people who use these platforms as discursive spaces for their self-presentation. Through these platforms, young people engage with dominant norms and societal expectations surrounding gender and attempt to perform a successful visual self that reflects their overall identity. However, these norms and expectations can lead to the perpetuation of gender stereotypes and conventional beauty standards. On the other hand, social media also provide a space for challenging traditional gender norms and celebrating non-conforming identities. This study focuses on exploring how young people negotiate and make sense of femininity and masculinity in the digital environment through the creation of fictitious social media profiles using mood boards. Through the analysis of the resulting characters created by our participants, we explored how these visual artefacts tend to reflect or subvert current stereotypes of masculinity and femininity.

description: Many countries in sub-Saharan Africa have liberalized markets to improve efficiency and enhance market linkages for smallholder farmers. The expected positive response by the private sector in areas with limited market infrastructure has however been disappointing. The functioning of markets is constrained by high transaction costs and coordination problems along the production-to-consumption value chain. New kinds of institutional arrangements are needed to reduce these costs and fill the vacuum left when governments withdrew from markets in the era of structural adjustments. One of these institutional innovations has been the strengthening of producer organizations and formation of collective marketing groups as instruments to remedy pervasive market failures in rural economies. The analysis presented here with a case study from eastern Kenya has shown that while collective action – embodied in Producer Marketing Groups (PMGs) – is feasible and useful, external shocks and structural constraints that limit the volume of trade and access to capital and information require investments in complementary institutions and coordination mechanisms to exploit scale economies. The effectiveness of PMGs was determined by the level of collective action in the form of increased participatory decision making, member contributions and initial start-up capital. Failure to pay on delivery, resulting from lack of capital credit, is a major constraint that stifles PMG competitiveness relative to other buyers. These findings call for interventions that improve governance and participation; mechanisms for improving access to operating capital; and effective strategies for risk management and enhancing the business skills of the PMGs.

description: The maintenance of crop diversity on farmers’ fields in hot spots of plant genetic diversity is considered a ”global life insurance policy“ in the Convention on Biological Diversity (CBD 2001:1). This paper provides evidence of the importance of the contribution of poor women farmers to the conservation and utilization of plant genetic resources (PGR) for food and agriculture. As a consequence, its equitable recognition and economic reward is a key issue in the sustainable management of agrobiodiversity. The present investigation into the institutions governing PGR, with special emphasis on gender equity and collective action, focuses on the identification of innovative institutions with special focus on women’s interests. The paper considers empirical evidence from Kerala, a hot spot of biodiversity in India, investigates properties of local biodiversity resources, and the role of collective action in conservation. To help understand conservation and utilization of agrobiodiversity the investigation uses a combination of institutional and gender analysis.

description: The outbreak of corona virus disease 2019 (COVID-19), caused by the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has already created emergency situations in almost every country of the world. The disease spreads all over the world within a very short period of time after its first identification in Wuhan, China in December, 2019. In India, the outbreaks starts on $2^{nd}$ March, 2020 and after that the cases are increasing exponentially. Very high population density, the unavailability of specific medicines or vaccines, insufficient evidences regarding the transmission mechanism of the disease also make it difficult to fight against the disease properly in India. Mathematical models have been used to predict the disease dynamics and also to assess the efficiency of the intervention strategies in reducing the disease burden. In this work, we propose a mathematical model to describe the disease transmission mechanism between the individuals. We consider the initial phase of the outbreak situation in India and our proposed model is fitted to the daily cumulative new reported cases during the period $2^{nd}$ March, 2020 to $24^{th}$ March, 2020. We estimate the basic reproduction number $(R_0)$, effective reproduction number (R(t)) and epidemic doubling time from the incidence data for the above-mentioned period. We further assess the effect of preventive measures such as spread of awareness, lock-down, proper hand sanitization, etc. in reducing the new cases. Two intervention scenarios are considered depending on the variability of the intervention strength over the period of implementation. Our study suggests that higher intervention effort is required to control the disease outbreak within a shorter period of time in India. Moreover, our analysis reveals that the strength of the intervention should be strengthened over the time to eradicate the disease effectively.

description: Men and women participate in collective action for different purposes in northern Nigeria. Field work conducted in six villages show that while men engage in community activities such as road repairs, maintenance of schools and hospitals, refuse collection and maintenance of the traditional village government, women mobilize around activities such as savings, house and farm work and care giving. It is argued that men mobilize around community activities outside the home because of their public orientation and because they want to maintain their dominance of that space. Women, in contrast, mobilize around activities in keeping with their domestic orientation and traditional roles such as care giving and housework. Religion also influences the extent of women’s participation in collective action. Because men have command of community institutions, they are better able to access the resources embedded in these institutions, but women are able to negotiate within established social structures for better conditions. Given the socio-cultural characteristics of communities in northern Nigeria, an effective strategy for collective action is collaboration between men’s and women’s groups rather than separatism or integration.
Coping With Gender Norms. Constructions of Masculinity Between Autonomy and Dependence
Creators: name: Fidolini, Vulca
Publisher: name: Italian Sociological Review
Year: 2024

description: This article aims to discuss gender identification processes as a dialectic of autonomy and dependence with respect to the production of hegemonic models of masculinity. The analysis which are proposed in this paper are based on results from a prolonged qualitative research on sexual conducts and construction of masculinities among young Moroccan and Muslim immigrant men living in Europe (France and Italy).

By discussing specific case studies, I will analyse predatory masculinity – one of the hegemonic representations of “being a man” among the young people interviewed – as a gender performance where heterosexuality is conceived as an “essential” attribute of men. The text will first explore how this model of masculinity is configured as a normative reference by scientific literature on Islamic masculinities and among the young Moroccans I met. Then, I will show how this model allows the production of different social relations, especially between men, in homosocial spaces within immigrant milieu, and between Morocco and Europe. Finally, I will study the case of those young men who come to terms with this predatory model of masculinity in order to negotiate subordinate sexual orientations, such as homosexual. The paper will try to show how young men both develop new margins of manoeuvre to perform their masculinities and experience the coercive power of gender norms according to their social backgrounds and family origins. The main purpose of the text is an attempt to highlight both constricting and productive power of heterosexuality and its plural forms of expression.

description: There have been many discussions of two-mode models for Bose condensates in a double well potential, but few cases in which parameters for these models have been calculated for realistic situations. Recent experiments lead us to use the Gross-Pitaevskii equation to obtain optimum two-mode parameters. We find that by using the lowest symmetric and antisymmetric wavefunctions, it is possible to derive equations for a more exact two-mode model that provides for a variable tunneling rate depending on the instantaneous values of the number of atoms and phase differences. Especially for larger values of the nonlinear interaction term and larger barrier heights, results from this model produce better agreement with numerical solutions of the time-dependent Gross-Pitaevskii equation in 1D and 3D, as compared with previous models with constant tunneling, and better agreement with experimental results for the tunneling oscillation frequency [Albiez et al., cond-mat/0411757]. We also show how this approach can be used to obtain modified equations for a second quantized version of the Bose double well problem.

description: Changing agricultural research and extension systems mean that informal mechanisms of information diffusion are often the primary source of information about improved seed and practices for farmers in sub-Saharan Africa. This paper investigates the interactions between gender, social capital and information exchange in rural Uganda. Within the framework of farmer-to-farmer models, we conceptualize the informal information diffusion process to comprise social capital accumulation and information exchange. We assume that each agent participates in information exchange with a fixed (predetermined) level of social capital and examine how endowments of social capital influence information exchange, paying close attention to gender differences. A multinomial logit model is used to analyze multiple participation choices of information exchange facing the farmer. Findings demonstrate that social capital is an important factor in information exchange, with men generally having better access to social capital than women. We also find strong evidence in support of group-based technology dissemination systems.

An ecology centre and trail system for the Tsolum River watershed

Publisher: name: University of British Columbia
Year: 2009

description: The Tsolum River flows through the Comox Valley on Vancouver Island, British Columbia, Canada. A local stream stewardship group, the Tsolum River Restoration Society, has been working to restore the river's once-plentiful salmon population. The Society's director has expressed an interest in developing an interpretive trail system, based at an ecology-centre facility, to link their salmon habitat enhancement projects and explain them to the public. From this idea, the project's scope was expanded by the author, based on the rationale that the trail planning should encompass a broader program. As public trail development opportunities are rare, it was felt that the system should achieve the Society's goals, while providing an enjoyable recreational experience; accessing outstanding cultural and natural features; linking to other routes or trails; and providing an aesthetic experience. This project provides planning and design recommendations for achieving these objectives. Results of the project, including maps, diagrams, plans, and drawings, will be presented and discussed. Suitability analysis, utilizing a Geographic Information System, is the primary method used in data synthesis and trail layout. A theoretical paradigm, the Ecological Aesthetic, and associated methodologies will be discussed, and applications to the project will be described and assessed.

description: We discuss a doubly-holographic prescription for black holes in braneworlds with a vanishing cosmological constant. It involves calculating Ryu-Takayanagi surfaces in AdS black funnel spacetimes attached to braneworld black holes in the $ critical$ Randall-Sundrum II model. Critical braneworlds have the virtue of having massless gravitons. Our approach should be useful when the braneworld is a cosmological black hole interacting with deconfined, large-$N$ matter. In higher dimensions, explicit funnel metrics will have to be constructed numerically -- but based on the general structure of the geometry, we present a natural guess for where one might find the semi-classical island. In a 3-dimensional example where a toy analytic black funnel is known, we can check our guess by direct calculation. We argue that this resolves a version of the information paradox in these braneworld systems, by finding strong evidence for "cosmological islands". Comoving Ryu-Takayanagi surfaces and associated UV cut-offs on the brane, play natural roles.

From the conservation of genetic diversity to the promotion of quality foodstuff: can the French model of 'Appellation d'Origine Contrôlée' be exported?

description: Building on ongoing research, this paper aims at suggesting alternative ways to conventional IPR systems to promote local varieties and related knowledge in developing countries. Many attempts to protect genetic diversity and local knowledge through IPR are in jeopardy because of misunderstanding on the terms of the debate and misrepresentation of the claims and interests of the various stakeholders. The paper then suggests that to improve rural livelihood conditions and promote genetic diversity conservation, it would be more efficient and satisfactory for the parties involved to build on local perceptions of foodstuff production and associated knowledge. It is easier and more feasible to stress the importance of a given know-how in the processing of products from genetically diversified or highly specific resources, than to isolate indigenous or local contributions in the conservation of genetic resources. This simplifies the remuneration issue and reinforces the legitimacy of local claims. Finally the paper discusses the feasibility, expected advantages and drawbacks of an adaptation of the French system of Appellation d’Origine Contrôlée (AOC) — a type of geographical indication of origin — for developing countries.

description: Recent adhesive research starts to consider more process oriented problems, in addition to the classical static stress and strength related topics, thus shifting towards a more global view on adhesive bonding. This includes the consideration of adhesive flow during application and joining of the substrates with all the information about initial application pattern and the resulting adhesive distribution contained after joining. Since the surface condition plays a major role and various different pretreatments are commonly used to improve the strength and durability of bonded joints while modifying their surface structure, the question of whether this influences the dynamics of the squeeze flow – or not – is addressed in this paper. In particular the materials glass and steel in combination with two designated surface pretreatments (blasting and flame-treatment) as well as their respective untreated reference surface are considered. For validation purposes the surfaces were characterized by means of roughness Ra and contact angle θ measurements, performed before and after the pretreatment, which resulted in a range of surface parameters for Ra from almost 0 to 3.3 μm and for θ from approximately 0 to 35°. However based on the measured force–displacement behaviour during the squeeze process no statistically significant difference regarding the dynamics of the adhesive flow could be observed between the untreated and pretreated surfaces for all investigated materials.

description: The indigenous people of Talaanding in Basac village, Bukidnon, the Philippines, had to deal with a high occurrence of disease and a high number of malnourished children in their village. This situation was due to the inability of the local health clinic to provide adequate health service and medicine to the community. Using an approach that promotes social learning and collective action, a CIFOR Adaptive Collaborative Management (ACM) research team facilitated a group of women, mostly the village health workers, in addressing their local health problems by using their local knowledge of medicinal plants and herbal medicines. This paper describes the ACM concept and the social learning processes that the women went through in identifying their health-related problems in the village, devising strategies to deal with those problems, monitoring the outcomes of their action, and improving their subsequent strategies. This paper also shows that the ACM processes promoted not only collective action and social learning among the women, but also helps to revive local knowledge of herbal medicines and conserve genetic resources in the area. The sustainability of the women’s efforts will depend on their ability to mobilize more community members to manage the established herb gardens, to enforce rules so that the costs and benefits of the gardens can be shared more equally, to link-up with local government and other stakeholders, and to continuously learn and adapt their management strategies.

Model parameters are estimated using Bayesian Markov chain Monte Carlo methods. The main results are as follows. Speculation, scalping, and petroleum inventories are found to be important in explaining oil price variation. Several properties of crude oil price dynamics are established, including mean-reversion, a negative correlation between price and volatility, volatility clustering, and infrequent compound jumps. We find evidence of volatility spillover among crude oil, corn, and wheat markets after the fall of 2006. This could be largely explained by tightened interdependence between these markets induced by ethanol production.

description: The resonance D*_sJ (2317) which is considered to be the 1^3P_0 state composed of charm and strange quarks has been discovered recently. The measured mass, which is about 160 MeV lower than the mass of the 1^3P_0 state obtained from the potential model calculation by Godfrey and Isgur, was considered surprisingly low and attracted a lot of theoretical investigations. We calculate the mass shift of the 1^3P_0 state by using the coupled channel e#ect. Our result shows that the coupled channel e#ect naturally explains the low mass of D*_sJ (2317).

description: We point out that the successful generation of the electroweak scale via gravitational instanton configurations in certain scalar-tensor theories can be viewed as the aftermath of a simple requirement: the existence of a quadratic pole with a sufficiently small residue in the Einstein-frame kinetic term for the Higgs field. In some cases, the inflationary dynamics may also be controlled by this residue and therefore related to the Fermi-to-Planck mass ratio, up to possible uncertainties associated with the instanton regularization. We present here a unified framework for this hierarchy generation mechanism, showing that the aforementioned residue can be associated with the curvature of the Einstein-frame target manifold in models displaying spontaneous breaking of dilatations. Our findings are illustrated through examples previously considered in the literature.

description: Material strain has recently received growing attention as a complementary resource to control the energy levels of quantum emitters embedded inside a solid-state environment. Some rare-earth ion dopants provide an optical transition which simultaneously has a narrow linewidth and is highly sensitive to strain. In such systems, the technique of spectral hole burning, in which a transparent window is burnt within the large inhomogeneous profile, allows to benefit from the narrow features, which are also sensitive to strain, while working with large ensembles of ions. However, working with ensembles may give rise to inhomogeneous responses among different ions. We investigate experimentally how the shape of a narrow spectral hole is modified due to external mechanical strain, in particular, the hole broadening as a function of the geometry of the crystal sites and the crystalline axis along which the stress is applied. Studying these effects are essential in order to optimize the existing applications of rare-earth doped crystals in fields which already profit from the more well-established coherence properties of these dopants such as frequency metrology and quantum information processing, or even suggest novel applications of these materials, for example as robust devices for force-sensing or highly sensitive accelerometers.

description: Carbon nanotube field-effect transistors with sub 20 nm long channels and on/off current ratios of > 1000000 are demonstrated. Individual single-walled carbon nanotubes with diameters ranging from 0.7 nm to 1.1 nm grown from structured catalytic islands using chemical vapor deposition at 700 degree Celsius form the channels. Electron beam lithography and a combination of HSQ, calix[6]arene and PMMA e-beam resists were used to structure the short channels and source and drain regions. The nanotube transistors display on-currents in excess of 15 microA for drain-source biases of only 0.4 Volt.

description: This paper focuses on methods for assessing the territorial impact (economic, social and environmental) of geographical indication systems. First, in a review of methods, methodological difficulties and choices are discussed and major studies are briefly presented. We highlight that it is necessary to identify a clear reference point and a relevant set of indicators and that this question has led to an active and rich research corpus. In a second part, we present some of the results of a recent European research program, SINER-GI. We analyze the impacts of 14 case studies in a common methodology. The results show significant differences of the priorities of the stakeholders between established geographical indications and geographical indications in progress. For a first group of geographical indications in progress, which we called “enthusiasts”, the most important expected impacts are the market stabilization or increase, the value added in the region, but also the preservation of local breeds or varieties. For a second group of geographical indications in progress, that we called “socio-environmentalists”, the expectations on economic issues are less important than the social and the environmental ones. Finally, for a third group of geographical indications in progress, that we called “undecided”, we find that the highest scores are given to the expected economic impacts. We can conclude that in general, observed or expected impacts of geographical indication systems are mainly linked with economic or economic-related issues. But the review of the 14 case studies also shows that if the economic concerns are the only motives in the implementation of the GI protection schemes, there are some crucial risks.
Semirelativistic potential model for glueball states

description: The masses of two-gluon glueballs are studied with a semirelativistic potential model whose interaction is a scalar linear confinement supplemented by a one-gluon exchange mechanism. The gluon is massless but the leading corrections of the dominant part of the Hamiltonian are expressed in terms of a state dependent constituent gluon mass. The Hamiltonian depends only on 3 parameters: the strong coupling constant, the string tension, and a gluon size which removes all singularities in the leading corrections of the potential. Accurate numerical calculations are performed with a Lagrange mesh method. The masses predicted are in rather good agreement with lattice results and with some experimental glueball candidates.

description: We present the analytical result of the expectation value of spin resulting from an injected spin polarized electron into a semi-infinitely extended 2DEG plane with [001] growth geometry via ideal quantum point contact. Both the Rashba and Dresselhaus spin-orbit couplings are taken into account. A pictorial interpretation of the spin precession along certain transport directions is given. The spin precession due to the Rashba term is found to be especially interesting since it behaves simply like a windshield wiper which is very different from the ordinary precession while that due to the Dresselhaus term is shown to be crystallographic-direction-dependent. Some crystallographic directions with interesting and handleable behavior of spin precession are found and may imply certain applicability in spintronic devices.
