title: Practices of Violence between Culture, Cognition and Economics. The Case of Youth Gangs in El Salvador
Creators: name: Warnecke, Hannes
Publisher: name: University Library Heidelberg
Year: 2015

description: Theoretically, this article focuses on the causes of the social organization of violence. Whereas approaches of political economy accentuate context conditions and changing opportunities for the use of violence, cultural approaches centre on the narratives of the violent act and therefore on the description of violence. Linking both arguments through the recourse on new insights first in cognitive science and second in practice theory allows explaining forms of violence, hence, the social organization of violence through time and space. It is further argued that the reproduction of practices of violence heavily depends on the appropriation of symbolical as well as material resources. At the same time, specific cultural schemata need to be activated. Therefore, the explanation of the social organization of violence is rooted in the interplay of both levels. Taking Salvadorian youth gangs as an example,
this article applies the elaborated theoretical approach to show firstly how youth gangs evolved with the organization of symbolical resources and on traditional cultural schemata. Second, the dynamics of these youth gangs are illustrated and their subsequent transformation towards local violent broker accentuated.

description: The utility of a passive fourth-harmonic cavity plays key role in suppressing longitudinal beam instabilities in the electron storage ring and lengthens the bunch by a factor of 2.6 for the phase II project of Hefei Light Source(HLS II). Meanwhile, instabilities driven by higher-order modes(HOM) may limit the performance of the higher-harmonic cavity. In this paper, the parasitic coupled-bunch instability which is driven by narrow band parasitic modes and the microwave instability which is driven by broadband HOM are both modeled analytically. The analytic modeling results are in good agreement with that of our previous simulation study and indicate that the passive fourth-harmonic cavity suppresses parasitic coupled-bunch instabilities and the microwave instability. The modeling suggests that a fourth-harmonic cavity may be successfully used at HLS II.

A note on marginal posterior simulation via higher-order tail area approximations

Publisher: name: arXiv
Year: 2012
Subjects: subject: Computation (stat.CO)
subject: FOS: Computer and information sciences

description: We explore the use of higher-order tail area approximations for Bayesian simulation. These approximations give rise to an alternative simulation scheme to MCMC for Bayesian computation of marginal posterior distributions for a scalar parameter of interest, in the presence of nuisance parameters. Its advantage over MCMC methods is that samples are drawn independently with lower computational time and the implementation requires only standard maximum likelihood routines. The method is illustrated by a genetic linkage model, a normal regression with censored data and a logistic regression model.
Hydrostratigraphy and allostratigraphy of the Cenozoic alluvium in the northwestern part of Las Vegas Valley, Clark County, Nevada
Creators: name: Donovan, David Joseph
Publisher: name: University of Nevada, Las Vegas
Year: 2005

description: This investigation was conducted to determine the location, nature, and boundaries of the most permeable unit within the alluvial aquifer material in Las Vegas Valley. It was prompted by declines in specific capacity of about 90% at the Las Vegas Valley Water District's West Central Well Field. It was hypothesized that the decline in specific capacity resulted from dewatering of the most permeable interval of the alluvium. Lithologic descriptions from wells and aquifer test information were analyzed for geologic and hydrogeologic variability. New information, in the form of detailed unpublished lithologic and hydrologic information, was available from twenty water wells drilled between 1989 and 1994; The geology was defined using allostratigraphic units; Aquifer test and lithologic information was used to define the boundaries of units of differing permeability within the subsurface. These units of differing permeability are the six (6) hydrostratigraphic units introduced in this investigation. The most permeable hydrostratigraphic unit is a distinct 20 to 90 m thick horizon, lying generally above 230 m below land surface. When the production wells were first installed at the West Central Well Field in the 1960's, most of the permeable unit was saturated. In 1993 the potentiometric surface was at or below the bottom of this hydrostratigraphic unit. (Abstract shortened by UMI.).

title: Violence and Remembrance. The Presence of the Past in the Ingush-Ossetian Armed Conflict
Creators: name: Jirouš, Dana
Publisher: name: University Library Heidelberg
Year: 2015

description: This paper analyzes processes of remembrance as a legitimizing ressource in the mobilization process of the Ingush-Ossetian violent conflict (1992). The analysis of collective remembrance in this conflict shows that there are four principles that the ingush conflict actors use in order to legitimize their claims to the territory of Prigorodnyj Rajon. These four principles are also found in the narratives of former inhabitants of the disputed territory. The study shows that narratives of the inhabitants' parents or grandparents complete and strengthen the publicly used memory-based arguments. Reasoning based on collective remembrance is particularly convincing when public representations of the past (collective memory) overlap with individual and communicative remembrance. In addition, processes of communicative remembrance do not only transfer concrete representations of past events but also emotions from one generation to the next that the latter adopt against the background of their own experiences. In conclusion, to contain violent conflicts one has to consider processes of remembrance as potentially mobilizing factors in the escalation of ethnic conflicts. Doing this it is essential to look at collective remembrance at societal level as well as individual and communicative remembrance.

Interactions and Asymptotics of Dispersive Shock Waves -- Korteweg-de Vries Equation

description: The long-time asymptotic solution of the Korteweg-de Vries equation for general, step-like initial data is analyzed. Each sub-step in well-separated, multi-step data forms its own single dispersive shock wave (DSW); at intermediate times these DSWs interact and develop multiphase dynamics. Using the inverse scattering transform and matched-asymptotic analysis it is shown that the DSWs merge to form a single-phase DSW, which is the `largest' one possible for the boundary data. This is similar to interacting viscous shock waves (VSW) that are modeled with Burgers' equation, where only the single, largest-possible VSW remains after a long time.

description: We have conducted B, g, V, and R-band imaging in a 45x40 arcmin^2 field containing part of the high Galactic latitude translucent cloud MBM32, and correlated the intensity of diffuse optical light S_ν(λ) with that of 100 micron emission S_ν(100um). A chi^2 minimum analysis is applied to fit a linear function to the measured correlation and derive the slope parameter b(λ)= ΔS_ν(λ) / ΔS_ν(100um) of the best-fit linear function. Compiling a sample by combining our b(λ) and published ones, we show that the b(λ) strength varies from cloud to cloud by a factor of 4. Finding that b(λ) decreases as S_ν(100um) increases in the sample, we suggest that a non-linear correlation including a quadratic term of S_ν(100um)^2 should be fitted to the measured correlation. The variation of optical depth, which is A_V = 0.16 - 2.0 in the sample, can change b(λ) by a factor of 2 - 3. There would be some contribution to the large b(λ) variation from the forward-scattering characteristic of dust grains which is coupled to the non-isotropic interstellar radiation field (ISRF). Models of the scattering of diffuse Galactic light (DGL) underestimate the b(λ) values by a factor of 2. This could be reconciled by deficiency in UV photons in the ISRF or by a moderate increase in dust albedo. Our b(λ) spectrum favors a contribution from extended red emission (ERE) to the diffuse optical light; b(λ) rises from B to V faster than the models, seems to peak around 6000 Å, and decreases towards long wavelengths. Such a characteristic is expected from the models in which the DGL is combined with ERE.

Ecological succession on abandoned roads in the Lake Mead National Recreation Area
Creators: name: Bolling, John Daniel
Publisher: name: University of Nevada, Las Vegas
Year: 2007

description: With the intent of describing the processes controlling desert succession, I examined soil and vegetation dynamics along a chronosequence of abandoned roads in the Mojave Desert. Early successional shrubs dominated younger roads; the long-lived Larrea tridentata dominated older roads. Soils on roads were more compacted, and had higher bulk densities, lower available phosphorus and lower total nitrogen than adjacent control areas. No soil factors changed significantly with road age, perhaps due to the observed high spatial heterogeneity. Fertile island development was also slow to occur on roads. Roads created by surface vehicular traffic had higher levels of shrub cover, soil compaction, clay and organic matter, lower available nutrients, and more pronounced fertile island development than roads created by bulldozing. Studies of succession in deserts must take into account natural patterns of plant and soil heterogeneity and initial disturbance type as first steps to understanding recovery from disturbance.
Prethermalization and dynamical transition in an isolated trapped ion spin chain

description: We propose an experimental scheme to observe prethermalization and dynamical transition in one-dimensional XY spin chain with long range interaction and inhomogeneous lattice spacing, which can be readily implemented with the recently developed trapped-ion quantum simulator. Local physical observables are found to relax to prethermal values at intermediate time scale, followed by complete relaxation to thermal values at much longer time. The physical origin of prethermalization is explained by spotting a non-trivial structure in lower half of the energy spectrum. The dynamical behavior of the system is shown to cross difference phases when the interaction range is continuously tuned, indicating the existence of dynamical phase transition.

description: The Opalinus Clay (OPA) formation is considered a suitable host rock candidate for nuclear waste storage. However, the sealing integrity and long-term safety of OPA are potentially compromised by pre-existing natural or artificially induced faults. Therefore, characterizing the mechanical behavior and microscale deformation mechanisms of faults and the surrounding rock is relevant for predicting repository damage evolution. In this study, we performed triaxial tests using saw-cut samples of the shaly and sandy facies of OPA to investigate the influence of pressure and mineral composition on the deformation behavior during fault reactivation. Dried samples were hydrostatically pre-compacted at 50 MPa and then deformed at constant strain rate, drained conditions and confining pressures (pc) of 5–35 MPa. Mechanical data from triaxial tests was complemented by local strain measurements to determine the relative contribution of bulk deformation and fault slip, as well as by acoustic emission (AE) monitoring, and elastic P-wave velocity measurements using ultrasonic transmissions. With increasing pc, we observe a transition from brittle deformation behavior with highly localized fault slip to semi-brittle behavior characterized by non-linear strain hardening with increasing delocalization of deformation. We find that brittle localization behavior is limited by pc at which fault strength exceeds matrix yield strength. AEs were only detected in tests performed on sandy facies samples, and activity decreased with increasing pc. Microstructural analysis of deformed samples revealed a positive correlation between increasing pc and gouge layer thickness. This goes along with a change from brittle fragmentation and frictional sliding to the development of shear zones with a higher contribution of cataclastic and granular flow. Friction coefficient at fault reactivation is only slightly higher for the sandy (µ ~ 0.48) compared to the shaly facies (µ ~ 0.4). Slide-hold-slide tests performed after ~ 6 mm axial shortening suggest stable creeping and long-term weakness of faults at the applied conditions. Our results demonstrate that the mode of fault reactivation highly depends on the present stress field and burial history.
A multi-level, time-series network analysis of the impact of youth peacebuilding on quality peace

description: Purpose Over 60% of armed conflicts re-occur; the seed of future conflict is sown even as a peace agreement is signed. The cyclical nature of war calls for a focus on youth who can disrupt this pattern over time. Addressing this concern, the developmental peace-building model calls for a dynamic, multi-level and longitudinal approach. Using an innovative statistical approach, this study aims to investigate the associations among four youth peace-building dimensions and quality peace. Design/methodology/approach Multi-level time-series network analysis of a data set containing 193 countries and spanning the years between 2011 and 2020 was performed. This statistical approach allows for complex modelling that can reveal new patterns of how different youth peace-building dimensions (i.e. education, engagement, information, inclusion), identified through rapid evidence assessment, promote quality peace over time. Such a methodology not only assesses between-country differences but also within-country change. Findings While the within-country contemporaneous network shows positive links for education, the temporal network shows significant lagged effects for all four dimensions on quality peace. The between-country network indicates significant direct effects of education and information, on average, and indirect effects of inclusion and engagement, on quality peace. Originality/value This approach demonstrates a novel application of multi-level time-series network analysis to explore the dynamic development of quality peace, capturing both stability and change. The analysis illustrates how youth peace-building dimensions impact quality peace in the macro-system globally. This investigation of quality peace thus illustrates that the science of peace does not necessitate violent conflict.

description: The Cenozoic strata of the Xining Basin, NE Tibet, have provided crucial records for understanding the tectonic and palaeo-environmental evolution of the region. Yet, the age of the lower part of the sedimentary stratigraphy and, consequently, the early tectonic evolution of the basin remain debated. Here, we present the litho- and magnetostratigraphy of various early Eocene sections throughout the Xining Basin independently constrained by the U–Pb radiometric age of a carbonate bed. Our study extends the dated stratigraphy down to 53.0 Ma (C24n.1r) and reveals highly variable accumulation rates during the early Eocene ranging from 0.5 to 8 cm/ka. This is in stark contrast to the low but stable accumulation rates (2–3 cm/ka) observed throughout the overlying Palaeogene and Neogene strata. Such a pattern of basin infill is not characteristic of flexural subsidence as previously proposed, but rather supports an extensional origin of the Xining Basin with multiple depocentres, which subsequently coalesced into a more stable and slowly subsiding basin. Whether this extension was related to the far-field effects of the subducting Pacific Plate or the India–Asia collision remains to be confirmed by future studies.
The cooling phase of Type I X-ray bursts observed with RXTE in 4U 1820-30 does not follow the canonical F - T^4 relation

description: We analysed the complete set of bursts from the neutron-star low-mass X-ray binary 4U 1820-30 detected with the Rossi X-ray Timing Explorer (RXTE). We found that all are photospheric radius expansion bursts, and have similar duration, peak flux and fluence. From the analysis of time-resolved spectra during the cooling phase of the bursts, we found that the relation between the bolometric flux and the temperature is very different from the canonical F - T^4 relation that is expected if the apparent emitting area on the surface of the neutron star remains constant. The flux-temperature relation can be fitted using a broken power law, with indices 2.0$\pm$0.3 and 5.72$\pm$0.06. The departure from the F - T^4 relation during the cooling phase of the X-ray bursts in 4U 1820-30 could be due to changes in the emitting area of the neutron star while the atmosphere cools-down, variations in the colour-correction factor due to chemical evolution, or the presence of a source of heat, e.g. residual hydrogen nuclear burning, playing an important role when the burst emission ceases.

description: A difficult challenge in physics education is to design professional development programs for teachers, which can lead to fundamental changes in their practise. We report all activities for physics teachers in the context of the National Plan for Scientific Degrees in Southern Tuscany. Research and practice have shown that physics teaching in school is inadequate. The main consequences are limited achievements in school, decrease of students' interests in learning physics and decrease of enrolments in physics in many countries. In recent years, the decline in enrolments was faced up with the launch of a wide national project addressed to secondary school students and teachers. The active involvement of teachers in the design of laboratories was found to be essential for obtaining actions which were not transitory and entered permanently in classroom practice. We describe some advanced courses in Physics and Mathematics Education realized few years ago and courses designed for a Master in Physics Educational Innovation and Orienting performed jointly by many Italian universities. Other activities are less formal but equally relevant, such as the active involvement of expert, young and in training teachers in designing and implementation of laboratory activities for a summer school of physics. Recently, we developed a workshop for teachers of physics and mathematics on modelling. which continued in an updating course for teachers in which selected topics, named in the same way in both disciplines, were discussed in order to design interdisciplinary learning paths. The purpose is to clarify these topics by using specific tools from physics and mathematics and to outline the similarities and the differences in both contexts. We describe teacher reactions and the more significant difficulties we encountered. Finally, we discuss which kind of activity seems more effective.

description: This paper proposes a practice-based perspective on how managers resource goal-directed networks in the public sector, especially those governed by a network administrative organization. While previous literature shows that network managers need to acquire and allocate resources in order to achieve network goals, little is known about specific resourcing practices and related challenges to resourcing goal-directed networks. To shed light on these issues, we outline a processual, multilevel, network-centric perspective that focuses on network resourcing practices and takes their interplay with network rules and goals into account. This paper shows that, to attain network goals, network managers need to mitigate developing tensions arising from the different interests of network members, external stakeholders, and the network itself, while navigating a trajectory of network resourcing. The paper contributes to the literature on public networks by examining potential sources of network-level resources; outlining basic resourcing practices of controlling, producing, reproducing, and transforming such resources; discussing multilevel tensions around network resourcing; and exploring trajectories of network resourcing. In addition, we propose avenues for empirical research on network resourcing.

description: We study the structure of weakly-closed nonself-adjoint algebras arising from representations of single vertex 2-graphs. These are the algebras generated by 2 isometric tuples which satisfy a certain commutation relation. We show that these algebras have a lower-triangular $3\times 3$ form. The left-hand side of this matrix decomposition is a slice of the enveloping von Neumann algebra generated by the 2-graph algebra. We further give necessary and sufficient conditions for these algebras themselves to be von Neumann algebras. The paper concludes with further study of atomic representations.

description: From the preference of one good over another, the strength of the preference cannot automatically be inferred. While money is the common denominator to assess the value of goods in humans, it appears difficult at first glance to put a price tag on the decisions of laboratory animals. Here we used consumer demand tests to measure how much work female mice expend to obtain access to different liquids. The mice could each choose between two liquids, one of which was free. The amount of work required to access the other liquid, by contrast, increased daily. In this way, the value of the liquid can be determined from a mouse's microeconomic perspective. The unique feature is that our test was carried out in a home-cage based setup. The mice lived in a group but could individually access the test-cage, which was connected to the home-cage via a gate. Thereby the mice were able to perform their task undisturbed by group members and on a self-chosen schedule with minimal influence by the experimenter. Our results show that the maximum number of nosepokes depends on the liquids presented. Mice worked incredibly hard for access to water while a bitter-tasting solution was offered for free whereas they made less nosepokes for sweetened liquids while water was offered for free. The results demonstrate that it is possible to perform automated and home-cage based consumer demand tests in order to ask the mice not only what they like best but also how strong their preference is.

This permits correlations to be assessed between the traits, while longitudinal ‘cross-lagged’ associations and cross-sectional correlations can be assessed between occasion-specific latent variables. We examined dynamic relationships between depressive symptoms and insulin resistance across five visits over 20 years of adulthood in the population-based Coronary Artery Risk Development in Young Adults (CARDIA) study. Possible differences based on population group (Black v. White participants), sex and years of education were tested. Depressive symptoms and insulin resistance were quantified using the Center for Epidemiologic Studies Depression (CES-D) scale and the homeostatic model assessment for insulin resistance (HOMA-IR), respectively. Results Among 4044 participants (baseline mean age 34.9 ± 3.7 years, 53% women, 51% Black participants), HOMA-IR and CES-D traits were weakly correlated (r = 0.081, p = 0.002). Some occasion-specific correlations, but no cross-lagged associations were observed overall. Longitudinal dynamics of these relationships differed by population groups such that HOMA-IR at age 50 was associated with CES-D score at age 55 (β = 0.076, p = 0.038) in White participants only. Longitudinal dynamics were consistent between sexes and based on education. Conclusions The relationship between depressive symptoms and insulin resistance was best characterized by weak correlations between occasion-specific states and enduring traits, with weak evidence that insulin resistance might be temporally associated with subsequent depressive symptoms among White participants later in adulthood.

description: Sources of entangled photon pairs are a key component in both fundamental tests of quantum theory and practical applications such as quantum key distribution and quantum computing. In this work, we describe and characterize a source of polarization entangled photon pairs based on two spontaneous parametric down-conversion (SPDC) crystals in a Sagnac interferometer. Our source is compact and produces high-quality entangled states in a very flexible manner. The wavelengths of the photon pairs, around 810 and 1550 nm, the phase between orthogonal components of the entangled state, and the tangle of the state are all independently adjustable. In addition to presenting basic characterization data, we present experimental violations of CHSH and Leggett inequalities, as well as an instance of the "beautiful" Bell inequality, which has not previously been tested experimentally.

description: Using Langevin dynamics simulations, we investigate the dynamics of polymer translocation into a circular nanocontainer through a nanopore under a driving force $F$. We observe that the translocation probability initially increases and then saturates with increasing $F$, independent of $ϕ$, which is the average density of the whole chain in the nanocontainer. The translocation time distribution undergoes a transition from a Gaussian distribution to an asymmetric distribution with increasing $ϕ$. Moreover, we find a nonuniversal scaling exponent of the translocation time as chain length, depending on $ϕ$ and $F$. These results are interpreted by the conformation of the translocated chain in the nanocontainer and the time of an individual segment passing through the pore during translocation.

Unbroken chain: Modern social banditry in South La
Creators: name: Harlan, Kenneth M

description: During the 1960s, America's cities experienced more than 200 cases of civil unrest. The purpose of these communal protests was to reverse oppression and create an order based on egalitarian principals. The first of these major urban rebellions occurred in Los Angeles, California in August 1965. The violence found in the South LA uprising represents the evolution of Eric Hobsbawm's social banditry paradigm. Modern social banditry is a combination of communal protest against oppressive forces and extralegal activity commonly associated with the vigilance movements of nineteenth-century America. This type of collective violence with its socioeconomic agenda seeks to emulate the philosophy of the legendary English bandit Robin Hood. Attacking the ruling hierarchy that has historically exploited the lower classes of society is a form of self-defense that supposedly creates more opportunities for economically depressed communities. The main targets for this attack on the dominant hierarchy are usually law enforcement and merchants that have no respect for the community's values. In South LA, these symptoms are present, and the community's reaction to social oppression reflects the illusionary quality of such protests.

description: The realization and detection of topological phases with ultracold atomic gases is at the frontier of current theoretical and experimental research. Here, we identify cold atoms in optical ladders subjected to synthetic magnetic fields as readily realizable bridges between one-dimensional spin-orbit (time reversal) topological insulators and two-dimensional Chern insulators. We reveal three instances of their promising potential: i) they realize spin-orbit coupling, with the left-right leg degree of freedom playing the role of an effective spin, ii) their energy bands and eigenstates exactly reproduce the topological chiral edge modes of two-dimensional Chern insulators, and iii) they can be tailored to realize a topological phase transition from a trivial to a topological insulating phase. We propose realistic schemes to observe the chiral and topological properties of ladder systems with current optical lattice-based experiments. Our findings open a door to the exploration of the physics of the edges of Chern insulators and to the realization of spin-orbit coupling and topological superfluid phases with ultracold atomic gases.

description: Why do we so often care about the outcomes of games when nothing is at stake? There is a paradox here, much like the paradox of fiction, which concerns why we care about the fates and threats of merely fictional beings. I argue that the paradox threatens to overturn a great deal of what philosophers have thought about caring, severing its connection to value and undermining its moral weight. I defend a solution to the paradox that draws on Kendall Walton's solution to the paradox of fiction, developing his idea that it be extended to games. The solution takes games to involve make-believe: in particular, players and spectators make-believe that the outcome of the game matters. I also explore how the phenomenon extends beyond games. And I explore some moral implications: in particular, my view preserves the idea that we have reason not to impede others in their pursuit of what they care about.

Maka'ainana (people of the land), the issue of Hawaiian sovereignty: The life cycle of Ka Lahui
Creators: name: Feldberg, Sonia
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: The Hawaiian people have been fighting to regain their sovereignty since the overthrow of the Hawaiian Nation in 1893. Throughout history many movements formed in response to this injustice. In 1987 Ka Lahui was formed as an initiative for self government to return Hawaii to the Kanaka MaoLi This study examines Ka Lahui by analyzing its rhetoric and placing it in the proper life cycle of a social movement. Also the strength of Ka Lahui's leader, Mililani Trask, will be analyzed. Social movements are pressured by many outside institutions. Ka Lahui's efforts are constantly being monitored by the Office of Hawaiian Affairs, which is an entity of the government. This opposition from outside forces will be addressed to complete this study of social movements.
Are auditory cues special? Evidence from cross-modal distractor-induced blindness

description: A target that shares features with preceding distractor stimuli is less likely to be detected due to a distractor-driven activation of a negative attentional set. This transient impairment in perceiving the target (distractor-induced blindness/deafness) can be found within vision and audition. Recently, the phenomenon was observed in a cross-modal setting involving an auditory target and additional task-relevant visual information (cross-modal distractor-induced deafness). In the current study, consisting of three behavioral experiments, a visual target, indicated by an auditory cue, had to be detected despite the presence of visual distractors. Multiple distractors consistently led to reduced target detection if cue and target appeared in close temporal proximity, confirming cross-modal distractor-induced blindness. However, the effect on target detection was reduced compared to the effect of cross-modal distractor-induced deafness previously observed for reversed modalities. The physical features defining cue and target could not account for the diminished distractor effect in the current cross-modal task. Instead, this finding may be attributed to the auditory cue acting as an especially efficient release signal of the distractor-induced inhibition. Additionally, a multisensory enhancement of visual target detection by the concurrent auditory signal might have contributed to the reduced distractor effect.
