Respect and Security Sector Reform
Creators: name: Levine, Daniel

Subjects: security sector reform

description: Security Sector Reform is now widely recognized as a crucial part of any conflict intervention or post-conflict reconstruction project. Where security forces are unable or unwilling to provide the population with basic safety and security, it is difficult if not impossible for other elements of societal development and healing to occur. While more attention is paid now to the moral elements of reform, such as inculcating respect for human rights and democratic governance, success in these elements of reform has been limited. Notably, though it has been the target of several major outside reform programs, the military of the Democratic Republic of Congo remains notorious for human rights abuses. This paper argues that the limited success of human rights training as part of SSR is a result not (only) of failures to teach human rights or build requisite systems of accountability, but rather of a fundamental need to reconceive what respecting human rights involves. Reform efforts need to treat human rights compliance as the effect of rebuilt, mutually respectful, practical social relationships, not as external standards to which compliance is secured by exhortation or incentive. This shift in conceptualization has implications for both the structure of reform programs and the way that outside reformers should conceive of their own social relationships with target militaries.

description: We investigate the effect of external pressure on the Fe magnetic moment in undoped LaOFeAs within the framework of density functional theory and show that this system is close to a magnetic instability: The Fe moment is found to drop by nearly a factor of 3 within a pressure range of $\pm$ 5 GPa around the calculated equilibrium volume. While the Fe moments show an unusually strong sensitivity to the spin arrangement (type of anti-ferromagnetic structure), the low temperature structural distortion is found to have only a minor influence on them. Analysis of the Fermi surface topology and nesting features shows that these properties change very little up to pressures of at least 10 GPa. We discuss the magnetic instability in terms of the itinerancy of this system.

description: The problem of diffusive bond-dissociation in a double well potential under application of an external force is scrutinized. We compute the probability distribution of rupture forces and present a detailed discussion of the influence of finite rebinding probabilities on the dynamic force spectrum. In particular, we focus on barrier crossing upon extension, i.e. under linearly increased load, and upon relaxation starting from completely separated bonds. For large loading rates the rupture force and the rejoining force depend on the loading rate in the expected manner determined by the shape of the potential. For small loading rates the mean forces obtained from pull and relax modes approach each other as the system reaches equilibrium. We investigate the dependence of the rupture force distributions and mean rupture forces on external parameters like cantilever stiffness and influence of a soft linker. We find that depending on the implementation of a soft linker the equilibrium rupture force is either unaffected by the presence of the linker or changes in a predictable way with the linker-compliance. Additionally, we show that it is possible to extract the equilibrium constant of the on- and off-rates from the determination of the equilibrium rupture forces.

description: V899 Mon is an eruptive young star showing characteristics of both FUors and EXors. It reached a peak brightness in 2010, then briefly faded in 2011, followed by a second outburst. We conducted multi-filter optical photometric monitoring, as well as optical and near-infrared spectroscopic observations of V899 Mon. The light curves and color-magnitude diagrams show that V899 Mon has been gradually fading after its second outburst peak in 2018, but smaller accretion bursts are still happening. Our spectroscopic observations taken with Gemini/IGRINS and VLT/MUSE show a number of emission lines, unlike during the outbursting stage. We used the emission line fluxes to estimate the accretion rate and found that it has significantly decreased compared to the outbursting stage. The mass loss rate is also weakening. Our 2D spectro-astrometric analysis of emission lines recovered jet and disk emission of V899 Mon. We found the emission from permitted metallic lines and the CO bandheads can be modeled well with a disk in Keplerian rotation, which also gives a tight constraint for the dynamical stellar mass of 2 ${M_{\odot}}$. After a discussion of the physical changes that led to the changes in the observed properties of V899 Mon, we suggest this object is finishing its second outburst.

An investigation of reading and conceptual tempo measures
Creators: name: Halpern, Honey Gael
Publisher: name: University of British Columbia
Year: 2010

description: This study gathered empirical data concerning the requirements of tasks utilized to measure reading in relation to the requirements of tasks utilized to measure conceptual tempo. The administration of the Matching Familiar Figures Test (MFFT) indicates either a reflective or an impulsive conceptual tempo. In order to investigate the possible relationship between conceptual tempo and reading, all subjects, impulsives and reflectives, were presented with reading tasks that approximated the MFFT in problem solving demands, and with reading demands that did not, i.e. some tasks with similar distractors and some with dissimilar distractors. The influence of the difficulty of the material was also investigated. The study employed both word recognition and comprehension tasks. One hundred and sixty-eight grade two students in New Westminister, British Columbia were administered the MFFT and the eight reading tasks. Second language learners and special education students were not included in the data analysis. The sample was identified as having middle socio-economic status by teachers and principals. The data were analyzed in a one-way MANOVA with conceptual tempo constituting the single independent variable. Impulsives and reflectives were compared across all the reading tasks in order to identify significant differences between the two groups. An alternate analysis of the data, a 2x2x2 MANOVA with repeated measures, was also performed. The dependent variables were comprehension and word recognition. The multivariate analysis of variance for conceptual tempo was found to be significant F (8/88) = 2.976, p = .005. In the word recognition tasks, when the distractors were similar, an effect of conceptual tempo is apparent, F (1 ) = 5-384, p = .021, F (1 ) = 5.997, p = .016. When the distractors were dissimilar, no effect of conceptual tempo is apparent, F (1 ) = 2.523, p = .111, F (1) = .001, p = .930. In the comprehension tasks, impulsives made more errors on both the similar and dissimilar tasks. Overall, the impulsives made more errors than the reflectives in reading tasks having similar distractors and impulsives made as many as or more errors than reflectives in reading tasks having dissimilar distractors. The results of the 2x2x2 MANOVA were similar to the one-way MANOVA.
Sizes of flaring kernels in various parts of the H-alpha line profile

description: In this paper we present new results of spectraphotometrical investigations of the flaring kernels sizes and their intensities measured simultaneously in various parts of the H-alpha line profile. Our investigations were based on the very high temporal resolution spectral-imaging observations of the solar flares collected with Large Coronagraph (LC), Multi-channel Subtractive Double Pass Spectrograph and Solar Eclipse Coronal Imaging System (MSDP-SECIS) at Bialkow Observatory (University of Wroclaw, Poland). We have found that the areas of the investigated individual flaring kernels vary in time and in wavelengths as well as the intensities and areas of the H-alpha flaring kernels decreased systematically when observed in consecutive wavelengths toward the wings of the H-alpha line. Our result could be explained as an effect of the cone-shaped lower parts of the magnetic loops channeling high energy particle beams exciting chromospheric plasma.

description: Gauge mediation models have two drawbacks, that is, the so-called μ-problem and a lack of predictability of the gravitino dark matter abundance. We show that conformal sequestering in the supersymmetry breaking sector offers attractive solutions to both problems. The correct mass scale of the μand B_μterms is generated by taking the gravitino mass of O(100) GeV without causing the flavor-changing neutral-current problem. Moreover, a large anomalous dimension of the supersymmetry breaking field naturally realizes the small stau and neutralino mass difference required for the coannihilation to work yielding the right dark matter abundance.

This interaction is taken into account at the level of production of intermediate pions. One of them, in turn, might be transited into $η$ or $η'$ mesons. Our results do not exceed the experimentally established branching fractions, and they are in agreement with the results of other theoretical studies.

description: We analytically examine the excitation of surface Josephson plasma waves (SJPWs) in periodically-modulated layered superconductors. We show that the absorption of the incident electromagnetic wave can be substantially increased, for certain incident angles, due to the resonance excitation of SJPWs. The absorption increase is accompanied by the decrease of the specular reflection. Moreover, we find the physical conditions guaranteeing the total absorption (and total suppression of the specular reflection). These conditions can be realized for Bi2212 superconductor films.

description: The interplay between non-trivial topological states of matter and strong electronic correlations is one of the most compelling open questions in condensed matter physics. Due to experimental challenges, there is an increasing desire to find more microscopic techniques to complement the results of more traditional experiments. In this work, we locally explore the Kondo insulator Sm$_{1-x}$Gd$_{x}$B$_{6}$ by means of electron spin resonance (ESR) of Gd$^{3+}$ ions at low temperatures. Our analysis reveals that the Gd$^{3+}$ ESR line shape shows an anomalous evolution as a function of temperature, wherein for highly dilute samples (x $\approx$ 0.0002) the Gd$^{3+}$ ESR line shape changes from a localized ESR local moment character to a diffusive-like character. Upon manipulating the sample surface with a focused ion beam we demonstrate, in combination with electrical resistivity measurements, that the localized character of the Gd$^{3+}$ ESR line shape is recovered by increasing the penetration of the microwave in the sample. This provides compelling evidence for the contribution of surface or near-surface excitations to the relaxation mechanism in the Gd$^{3+}$ spin dynamics. Our work brings new insights into the importance of non-trivial surface excitations in ESR, opening new routes to be explored both theoretically and experimentally.

What impact do same-sex classes have on a girl’s academic success, personality, and identity development, and what role do stakeholders and teachers play?
Creators: Iman Bateni
Publisher: name: University of Alberta Library
Year: 2023

Indeed, the influence of school on students' lives can be long-standing and shape their personalities. Many of us discover our true selves when interacting with our peers when studying at school. According to Pittman and Richmond (2007), students are academically affected while attending school, and that is why the significance of same-sex schools comes into play. The question proposed in this research is, “What impact do same-sex classes have on a girl’s academic success, personality, and identity development, and what role do stakeholders and teachers play?” As stakeholders gain a better understanding of the factors that contribute to the viability of same-sex schools, they can plan and adapt more accordingly in the future, based on new discoveries and research on how to optimize both learning and a safe environment free from stereotypes so that students in same-sex schools can thrive.

description: According to radiative models, radio galaxies are predicted to produce gamma-rays from the earliest stages of their evolution onwards. The study of the high-energy emission from young radio sources is crucial for providing information on the most energetic processes associated with these sources, the actual region responsible for this emission, as well as the structure of the newly born radio jets. Despite systematic searches for young radio sources at gamma-ray energies, only a handful of detections have been reported so far. Taking advantage of more than 11 years of Fermi-LAT data, we investigate the gamma-ray emission of 162 young radio sources (103 galaxies and 59 quasars), the largest sample of young radio sources used so far for a gamma-ray study. We analysed the Fermi-LAT data of each source separately to search for a significant detection. In addition, we performed the first stacking analysis of this class of sources in order to investigate the gamma-ray emission of the young radio sources that are undetected at high energies. In this note we present the results of our study and we discuss their implications for the predictions of gamma-ray emission from this class of sources.

description: Caliendo, Dvorkin and Parro (2019) presents a dynamic structural general equilibrium
model of trade that is very useful for analyzing the effects of trade shocks on employment and economic welfare in different sectors and U.S. states over time. In this
paper, I provide a simple application of this very complex model. While the simulations in Caliendo et al. (2019) combine shocks to all Chinese manufacturing sectors,
my simulation isolates the effects of productivity growth in a single sector, Plastics and
Rubber Products in China, in order to illustrate how a shock in one sector spills over to
sectors directly upstream and downstream and to the rest of the economy. I focus on
labor transitions over the short and long run and the distribution of employment and
welfare effects across U.S. states.
An investigation of physical setting in narrative discourse, and its influence on the reading comprehension and reading interest of elementary students
Creators: name: Craddock, Sonia
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to determine the extent to which the variable, physical setting, in narrative prose influenced the silent reading comprehension and expressed interest of sixth grade students when they read such narrative prose. Six stories, each with three treatment levels, were written. The treatment levels were: local physical setting, foreign physical setting, and non-specific physical setting. Each story was designed to control relevant qualitative and quantitative variables and difficulty level. Cloze tests were constructed over all the story versions to measure silent reading comprehension. Semantic Differential Scales were constructed to measure expressed interest in the stories. Three hundred and forty-four grade six students in Vancouver, B.C., from diverse socio-economic areas, read a randomized selection of the stories and completed the matching Cloze tests and a Semantic Differential for each story read. The Gates-MacGinitie Comprehension test was administered to the students and the scores were used to divide the subjects into three reading ability groups. Data were analyzed using a fixed effects 2x3x3 fully crossed factorial design with repeated measures over the six stories. Scheffe tests for multiple comparisons were used to determine differences among groups. Pearson Products-moment correlations were calculated to determine relationships between the two dependent variables. Reading comprehension was found to be significantly influenced by the physical setting in a story. The Cloze scores on the locally-set stories were reliably higher than the Cloze scores on both the foreign set stories, and on the non-specific set stories. Cloze scores on the non-specific set stories were reliably higher than on the foreign set stories. There was however, no significant difference on the comprehension scores between specific set and non-specific set stories. Interest was not significantly influenced by the setting of the stories, but was influenced by story difficulty, easy stories being significantly preferred over the harder stories for all reading groups. Although there was a significant relationship between comprehension and expressed interest, the relationship was not significantly influenced by the setting of the story.

description: The properties of the galaxy distribution at large scales are usually studied using statistics which are assumed to be self-averaging inside a given sample. We present a new analysis able to quantitatively map galaxy large scale structures while testing for the stability of average statistical quantities in different sample regions. We find that the newest samples of the Sloan Digital Sky Survey provide unambiguous evidence that galaxy structures correspond to large amplitude density fluctuations at all scales limited only by sample sizes. The two-point correlations properties are self-averaging up to approximately 30 Mpc/h and are characterized by a fractal dimension D=2.1 +- 0.1. Then at all larger scales probed density fluctuations are too large in amplitude and too extended in space to be self-averaging inside the considered volumes. These inhomogeneities are compatible with a continuation of fractal correlations but incompatible with: (i) a homogeneity scale smaller than 100 Mpc/h, (ii) predictions of standard theoretical models, (iii) mock galaxy catalogs generated from cosmological Nbody simuations.

The relationship between first grade children’s reading achievement and their performance on selected metalinguistic tasks
Creators: name: Bruinsma, Robert Walter
Publisher: name: University of British Columbia
Year: 2010

description: Objectives: The purpose of this study was first to conceptualize specific metalinguistic abilities related to reading acquisition and to provide a conceptually defensible rationale for the measurement of those abilities by a battery of tests. A second major purpose was to gather empirical data concerning the relationship of the defined metalinguistic abilities and reading achievement in a group of first grade children. A third purpose was to examine the influence of gender on reading achievement and performance on metalinguistic tasks. Procedure: A Test of Metalinguistic Awareness (TOMA) was developed and administered to 113 first grade subjects in March, 1981. In April, 1981, all subjects were administered the reading subtests of the Stanford Achievement Test Primary I. Factor analysis was used to determine the underlying factor structure of the TOMA. Multiple regression analyses were used to examine the relationships of the subtests of the TOMA to reading achievement. Results: Factor analysis revealed a two factor structure for the TOMA interpreted as a Function factor and a Structure factor. The Function factor was discovered to account for the greatest amount of the variance in reading achievement (R² = 0.24). Multiple regression analysis indicated that the entire TOMA accounted for about 31 percent of the variance in reading achievement and that TOMA Subtest 5 (Awareness of the language of instruction) alone accounted for 20 percent. There were no significant differences in reading achievement or metalinguistic awareness, as a function of gender. Conclusions: It was concluded by the experimenter that metalinguistic awareness as measured by the TOMA is a significant though limited predictor of reading achievement in grade one pupils similar in character to those used in the study. It was further concluded that awareness of functional aspects of language may be more important to reading acquisition and achievement than is awareness of structural aspects of language. The study concludes with a discussion of its limitations and suggestions for further research are presented.

description:  This article explores the dynamics between chaos and order as essential elements in the origin of life. The study proposes that moments of agitation and calm in the early universe created conditions conducive to the emergence of complex biological structures. Based on an interdisciplinary analysis that integrates scientific concepts of dynamical systems, theories of abiogenesis, and flagship experiments such as the Miller-Urey experiment, the paper discusses how self-organization emerged from the initial chaos, leading to the formation of replicating molecules and cells. In addition, the delicate balance maintained by living systems, where adaptability and stability coexist, is explored, reflecting on the implications of this process for continuous evolution and for the understanding of the mechanisms that sustain life. In short, the study offers a new perspective on how seemingly contrasting forces interconnect and complement each other to give birth to life, providing valuable insights for both science and philosophy

description: Unmeasured confounding is a threat to causal inference and gives rise to biased estimates. In this article, we consider the problem of individualized decision-making under partial identification. Firstly, we argue that when faced with unmeasured confounding, one should pursue individualized decision-making using partial identification in a comprehensive manner. We establish a formal link between individualized decision-making under partial identification and classical decision theory by considering a lower bound perspective of value/utility function. Secondly, building on this unified framework, we provide a novel minimax solution (i.e., a rule that minimizes the maximum regret for so-called opportunists) for individualized decision-making/policy assignment. Lastly, we provide an interesting paradox drawing on novel connections between two challenging domains, that is, individualized decision-making and unmeasured confounding. Although motivated by instrumental variable bounds, we emphasize that the general framework proposed in this article would in principle apply for a rich set of bounds that might be available under partial identification.

description: Bark beetle (Ips typographus) outbreaks have the potential to damage large areas of spruce-dominated forests in Scandinavia. To define forest management strategies that will minimize the risk of bark beetle attacks, we need robust models that link forest structure and composition to the risk and potential damage of bark beetle attacks. Since data on bark beetle infestation rates and corresponding damages does not exist in Norway, we implement a previously published meta-model for estimating I. typographus damage probability and intensity. Using both current and projected climatic conditions we used the model to estimate damage inflicted by I. typographus in Norwegian spruce stands. The model produces feasible results for most of Norway’s climate and forest conditions, but a revised model tailored to Norway should be fitted to a dataset that includes older stands and lower temperatures. Based on current climate and forest conditions, the model predicts that approximately nine percent of productive forests within Norway’s main spruce-growing region will experience a loss ranging from 1.7 to 11 m3/ha of spruce over a span of five years. However, climate change is predicted to exacerbate the annual damage caused by I. typographus, potentially leading to a doubling of its detrimental effects.

description: The location of Internet hosts is frequently used in distributed applications and networking services. Examples include customized advertising, distribution of content, and position-based security. Unfortunately the relationship between an IP address and its position is in general very weak. This motivates the study of measurement-based IP geolocation techniques, where the position of the target host is actively estimated using the delays between a number of landmarks and the target itself. This paper discusses an IP geolocation method based on crowdsourcing where the smartphones of users operate as landmarks. Since smartphones rely on wireless connections, a specific delay-distance model was derived to capture the characteristics of this novel operating scenario.

description: We construct different almost Poisson brackets for nonholonomic systems than those existing in the literature and study their reduction. Such brackets are built by considering non-canonical two-forms on the cotangent bundle of configuration space and then carrying out a projection onto the constraint space that encodes the Lagrange-D'Alembert principle. We justify the need for this type of brackets by working out the reduction of the celebrated Chaplygin sphere rolling problem. Our construction provides a geometric explanation of the Hamiltonization of the problem given by A. V. Borisov and I. S. Mamaev.

description: Fluctuations of gravitational forces cause so-called Newtonian noise (NN) in gravitational-wave (GW) detectors which is expected to limit their low-frequency sensitivity in upcoming observing runs. Seismic NN is produced by seismic waves passing near a detector's suspended test masses. It is predicted to be the strongest contribution to NN. Modeling this contribution accurately is a major challenge. Arrays of seismometers were deployed at the Virgo site to characterize the seismic field near the four test masses. In this paper, we present results of a spectral analysis of the array data from one of Virgo's end buildings to identify dominant modes of the seismic field. Some of the modes can be associated with known seismic sources. Analyzing the modes over a range of frequencies, we provide a dispersion curve of Rayleigh waves. We find that the Rayleigh speed in the NN frequency band 10 Hz - 20 Hz is very low ($\lesssim$100\,m/s), which has important consequences for Virgo's seismic NN. Using the new speed estimate, we find that the recess formed under the suspended test masses by a basement level at the end buildings leads to a 10 fold reduction of seismic NN.

High Energy Cosmic Rays from the Decay of Gravitino Dark Matter

description: We study gamma ray and positron in high energy cosmic ray from the decay of the gravitino dark matter in the framework of supersymmetric model with R-parity violation. Even though R-parity is violated, the lifetime of the gravitino, which is assumed to be the lightest superparticle, can be longer than the present age of the universe if R-parity violating interactions are weak enough. In such a case, gravitino can be dark matter of the universe and its decay produces high energy cosmic rays. We calculate the fluxes of gamma ray and positron from the decay of the gravitino dark matter and discuss implications of such a scenario to present and future observations. In particular, we show that excesses of the fluxes of gamma ray and positron observed by EGRET and HEAT experiments, respectively, can be simultaneously explained as the cosmic rays from the decay of the gravitino dark matter.

description: The observation of quantum conductance oscillations in mesoscopic systems has traditionally required the confinement of the carriers to a phase space of reduced dimensionality. While electron optics such as lensing and focusing have been demonstrated experimentally, building a collimated electron interferometer in two unconfined dimensions has remained a challenge due to the difficulty of creating electrostatic barriers that are sharp on the order of the electron wavelength. Here, we report the observation of conductance oscillations in extremely narrow graphene heterostructures where a resonant cavity is formed between two electrostatically created bipolar junctions. Analysis of the oscillations confirms that p-n junctions have a collimating effect on ballistically transmitted carriers. The phase shift observed in the conductance fringes at low magnetic fields is a signature of the perfect transmission of carriers normally incident on the junctions and thus constitutes a direct experimental observation of ``Klein Tunneling.''

description: The discovery of superconductivity in the infinite-layer nickelates has opened new perspectives in the context of quantum materials. We analyze, via first-principles calculations, the electronic properties of La$_2$NiO$_3$F -- the first single-layer T'-type nickelate -- and compare these properties with those of related nickelates and isostructural cuprates. We find that La$_2$NiO$_3$F is essentially a single-band system with a Fermi surface dominated by the Ni-3$d_{x^2-y^2}$ states with an exceptional 2D character. In addition, the hopping ratio is similar to that of the highest $T_c$ cuprates and there is a remarkable $e_g$ splitting together with a charge transfer energy of 3.6~eV. According to these descriptors, along with a comparison to Nd$_2$CuO$_4$, we thus indicate single-layer T'-type nickelates of this class as very promising analogs of cuprate-like physics while keeping distinct Ni$^{1+}$ features.

description: Less than $200$ radio-loud active galactic nuclei (AGN) are known above redshift $4$. Around $40$ of them have been observed at milliarcsecond (mas) scale resolution with very long baseline interferometry (VLBI) technique. Some of them are unresolved, compact, relativistically beamed objects, blazars with jets pointing at small angles to the observer's line of sight. But there are also objects with no sign of relativistic beaming possibly having larger jet inclination angles. In a couple of cases, X-ray observations indicate the presence of relativistic beaming in contrary to the VLBI measurements made with the European VLBI Network (EVN). J1420$+$1205 is a prominent example, where our $30-100$ mas-scale enhanced Multi Element Remotely Linked Interferometer Network (e-MERLIN) radio observations revealed a rich structure reminiscent of a small radio galaxy. It shows a bright hotspot which might be related to the denser interstellar medium around a young galaxy at an early cosmological epoch.

description: We investigate the implications of a tetraquark field on chiral symmetry restoration at nonzero temperature. In order for the chiral phase transition to be cross-over, as shown by lattice QCD studies, a strong mixing between scalar quarkonium and tetraquark fields is required. This leads to a light ($\sim0.4$ GeV), predominantly tetraquark state, and a heavy ($\sim1.2$ GeV), predominantly quarkonium state in the vacuum, in accordance with recently advocated interpretations of spectroscopy data. The mixing even increases with temperature and leads to an interchange of the roles of the originally heavy, predominantly quarkonium state and the originally light, predominantly tetraquark state. Then, as expected, the scalar quarkonium is a light state when becoming degenerate in mass with the pion as chiral symmetry is restored at nonzero temperature.

Chiral condensate in neutron matter

description: A recent chiral perturbation theory calculation of the in-medium quark condensate $$ is extended to the isospin-asymmetric case of pure neutron matter. In contrast to the behavior in isospin-symmetric nuclear matter we find only small deviations from the linear density approximation. This feature originates primarily from the reduced weight factors (e.g. 1/6 for the dominant contributions) of the $2π$-exchange mechanisms in pure neutron matter. Our result suggests therefore that the tendencies for chiral symmetry restoration are actually favored in systems with large neutron excess (e.g. neutron stars). We also analyze the behavior of the density-dependent quark condensate $(ρ_n)$ in the chiral limit $m_π\to 0$.
