description: Recent advances in genomic research have generated vast amounts of information that can help identify individuals who differ in their susceptibility to a particular disease or response to a specific treatment. This information may offer solutions for the treatment of complex chronic diseases that are influenced by a wide array of factors. This vast amount of information brings critical challenges in applying advanced technology to synthesize clinical-genomic patient data. Synthesizing this information is necessary to derive the knowledge that would empower physicians to provide personalized care with the best possible therapeutic interventions. We used statistical methods and data mining approaches to understand clinical-genomic risk factors that differentiate Type II Diabetes cases from healthy controls. We investigated whether inclusion of genomic risk factors in conjunction with clinical information improves classification accuracy. We also demonstrate how a biased and an unbiased method for selection of risk associated single nucleotide polymorphisms (SNPs) effect clustering along with clinical information. We determined the optimal method based on its clustering performance.

description: We present a method based on matched multifrequency filters for extracting cluster catalogs from Sunyaev-Zel'dovich (SZ) surveys. We evaluate its performance in terms of completeness, contamination rate and photometric recovery for three representative types of SZ survey: a high resolution single frequency radio survey (AMI), a high resolution ground-based multiband survey (SPT), and the Planck all-sky survey. These surveys are not purely flux limited, and they loose completeness significantly before their point-source detection thresholds. Contamination remains relatively low at <5% (less than 30%) for a detection threshold set at S/N=5 (S/N=3). We identify photometric recovery as an important source of catalog uncertainty: dispersion in recovered flux from multiband surveys is larger than the intrinsic scatter in the Y-M relation predicted from hydrodynamical simulations, while photometry in the single frequency survey is seriously compromised by confusion with primary cosmic microwave background anisotropy. The latter effect implies that follow-up observations in other wavebands (e.g., 90 GHz, X-ray) of single frequency surveys will be required. Cluster morphology can cause a bias in the recovered Y-M relation, but has little effect on the scatter; the bias would be removed during calibration of the relation. Point source confusion only slightly decreases multiband survey completeness; single frequency survey completeness could be significantly reduced by radio point source confusion, but this remains highly uncertain because we do not know the radio counts at the relevant flux levels.

A Monte Carlo simulation of a protein (CoVE) in a matrix of random barriers

subject: FOS: Physical sciences

description: Monte Carlo simulations are performed to study structure and dynamics of a protein CoVE in random media generated by a random distribution of barriers at concentration c with a coarse-grained model in its native (low temperature) and denatured (high temperature) phase. The stochastic dynamics of the protein is diffusive in denature phase at low c, it slows down on increasing c and stops moving beyond a threshold (cth = 0.10). In native phase, the protein moves extremely slow at low c but speeds up on further increasing c in a characteristic range (c = 0.10 - 0.20) before getting trapped at high c (cth = 0.30). The radius of gyration (Rg) of CoVE shows different non-monotonic dependence on c (increase followed by decay) in native and denature phase with a higher and sharper rate of change in farmer. Effective dimension (D) of CoVE is estimated from the scaling of structure factor: in denatured phase, D = 2 (a random coil conformation) at low c (= 0.01 - 0.10) with appearance of some globularization i.e. D ? 2.3, 2.5 at higher c (= 0.2, 0.3). Increasing c seems to reduce the globularity (D = 3) of CoVE in native phase.

description: We have carried out a hydrodynamical code comparison study of interacting multiphase fluids. The two commonly used techniques of grid and smoothed particle hydrodynamics (SPH) show striking differences in their ability to model processes that are fundamentally important across many areas of astrophysics. Whilst Eulerian grid based methods are able to resolve and treat important dynamical instabilities, such as Kelvin-Helmholtz or Rayleigh-Taylor, these processes are poorly or not at all resolved by existing SPH techniques. We show that the reason for this is that SPH, at least in its standard implementation, introduces spurious pressure forces on particles in regions where there are steep density gradients. This results in a boundary gap of the size of the SPH smoothing kernel over which information is not transferred.

description: In the last decades, much effort has been put into finding the star formation law which could unequivocally link the gas and the star formation rate (SFR) densities measured on sub-kiloparsec scale in star-forming galaxies. The conventional approach of using the observed surface densities to infer star formation laws has however revealed a major and well-known issue, as such relations are valid for the high-density regions of galaxies but break down in low-density and HI-dominated environments. Recently, an empirical correlation between the total gas (HI+H$_2$) and the star formation rate (SFR) volume densities was obtained for a sample of nearby disc galaxies and for the Milky Way. This volumetric star formation (VSF) law is a single power-law with no break and a smaller intrinsic scatter with respect to the star formation laws based on the surface density. In this work, we explore the VSF law in the regime of dwarf galaxies in order to test its validity in HI-dominated, low-density, and low-metallicity environments. In addition, we assess this relation in the outskirts of spiral galaxies, which are low-density and HI-dominated regions similar to dwarf galaxies. Remarkably, we find the VSF law, namely $ρ_\mathrm{SFR} \propto ρ_\mathrm{gas}^α$ with $α\approx 2$, is valid for both these regimes. This result indicates that the VSF law, which holds unbroken for a wide range of gas ($\approx 3$ dex) and SFR ($\approx 6$ dex) volume densities, is the empirical relation with the smallest intrinsic scatter and is likely more fundamental than surface-based star formation laws.

Self-rated health and chronic disease status: A biopsychosocial examination
Creators: name: Quinn, Noel Burns
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Poor self-rated health is consistently associated with increased mortality risk. Here we examined whether self-rated health was similarly related to prevalent chronic disease. We further evaluated potential biopsychosocial mediators of the association including biomedical (i.e. white blood cell, hemoglobin, total cholesterol, albumin, resting systolic blood pressure, estimated glomerular filtration rate, body mass index), psychological (i.e. anxiety, depressive symptoms, perceived stress), and social (i.e. healthcare barriers, and poverty status) factors. Race was explored as a moderator. Participants were 2,802 adults (56% female; mean age = 48 years; mean education = 12 years; 58% Black) from the Healthy Aging in Neighborhoods of Diversity Across the Lifespan study (HANDLS). Self-rated health was dichotomized into Good and Poor categories, and the number of chronic diseases (diagnosed via history, laboratory testing, and physical examination) were summed. Likelihood of chronic disease as a function of self-rated health and its interaction with race was examined in sex-stratified negative binomial regressions, adjusted for relevant demographic factors and health behaviors. Results showed that, irrespective of race, poor self-rated health was associated with increased likelihood for chronic disease  in men [OR = 1.26, 95% CI 1.070, 1.482] and women [OR = 1.32, 95% CI 1.157, 1.512]. Psychological factors attenuated this association for men (7%) and women (9%). Overall, the findings suggest that individuals may be largely accurate in evaluating their physical health status. However, further exploration of intermediary factors is warranted. Better understanding of how self-rated health impacts chronic disease may help clinicians identify individuals at greatest risk for mortality.

description: The goal of the current study was to develop a preliminary version of a measure of illness knowledge in parents of children with food allergy (The FAKT). The current study involved two phases. The first phase consisted of the construction of the FAKT; content was based on educational resources and allergist ratings of clinical importance. Items were based on allergist ratings and feedback from cognitive interviews with parents. The second phase consisted of a test of the measure with 317 mothers of children with food allergy. On the FAKT, participant total scores ranged from 32 to 88 (M = 79.28, SD = 6.67). Item difficulty and discrimination indices suggested that the FAKT contains several items that are appropriately difficult and discriminatory. Coefficient alpha was highly reliable for the FAKT (α = .868). This pilot test of the FAKT will serve as the basis for future refinements of this measure.

description: Observing planetary auroral radio emission is the most promising method to detect exoplanetary magnetic fields, the knowledge of which will provide valuable insights into the planet's interior structure, atmospheric escape, and habitability. We present LOFAR-LBA circularly polarized beamformed observations of the exoplanetary systems 55 Cancri, $\upsilon$ Andromedae, and $τ$ Boötis. We tentatively detect circularly polarized bursty emission from the $τ$ Boötis system in the range 14-21 MHz with a flux density of $\sim$890 mJy and with a significance of $\sim$3$σ$. For this detection, no signal is seen in the OFF-beams, and we do not find any potential causes which might cause false positives. We also tentatively detect slowly variable circularly polarized emission from $τ$ Boötis in the range 21-30 MHz with a flux density of $\sim$400 mJy and with a statistical significance of $>$8$σ$. The slow emission is structured in the time-frequency plane and shows an excess in the ON-beam with respect to the two simultaneous OFF-beams. Close examination casts some doubts on the reality of the slowly varying signal. We discuss in detail all the arguments for and against an actual detection. Furthermore, a $\sim$2$σ$ marginal signal is found from the $\upsilon$ Andromedae system and no signal is detected from the 55 Cancri system. Assuming the detected signals are real, we discuss their potential origin. Their source probably is the $τ$ Bootis planetary system, and a possible explanation is radio emission from the exoplanet $τ$ Bootis b via the cyclotron maser mechanism. Assuming a planetary origin, we derived limits for the planetary polar surface magnetic field strength, finding values compatible with theoretical predictions. Further low-frequency observations are required to confirm this possible first detection of an exoplanetary radio signal. [Abridged]

description: We explore how the IR pathologies of noncommutative field theory are resolved when the theory is realized as open strings in background B-fields: essentially, since the IR singularities are induced by UV/IR mixing, string theory brings them under control in much the same way as it does the UV singularities. We show that at intermediate scales (where the Seiberg-Witten limit is a good approximation) the theory reproduces the noncommutative field theory with all the (un)usual features such as UV/IR mixing, but that outside this regime, in the deep infra-red, the theory flows continuously to the commutative theory and normal Wilsonian behaviour is restored. The resulting low energy physics resembles normal commutative physics, but with additional suppressed Lorentz violating operators. We also show that the phenomenon of UV/IR mixing occurs for the graviton as well, with the result that, in configurations where Planck's constant receives a significant one-loop correction (for example brane-induced gravity), the distance scale below which gravity becomes non-Newtonian can be much greater than any compact dimensions.

description: The excitation energies of parahydrogen clusters have been systematically calculated by the diffusion Monte Carlo technique in steps of one molecule from 3 to 40 molecules. These clusters possess a very rich spectra, with angular momentum excitations arriving up to L=13 for the heavier ones. No regular pattern can be guessed in terms of the angular momenta and the size of the cluster. Clusters with N=13 and 36 are characterized by a peak in the chemical potential and a large energy gap of the first excited level, which indicate the magical character of these clusters. From the calculated excitation energies the partition function has been obtained, thus allowing for an estimate of thermal effects. An enhanced production is predicted for cluster sizes N=13, 31 and 36, in agreement with experiment.

description: Let a data stream have length m over an alphabet of n letters, with letter i occurring m_i times for i = 1,...,n: For any k, define the frequency moments F_k as F_k =sum_{i=1}^n m_i^k.  Alon, Matias, and Szegedy in 1999 showed how to estimate F_k for an integer k>=2; with a one-pass algorithm using O(n^{1-1/k} log(n)) space for given length m; accuracy, and confidence. Here we extend those results to non-integral k; obtaining bounds on the variance giving accuracy and confidence estimates, and giving quantitative results on the algorithm's space requirements, with particular interest to when k is near 1. We also give some performance statistics of the algorithm for these cases, considering an application to entropy estimation. This algorithm of AMS is known as a sketching algorithm. Sketching algorithms are probabilistic algorithms generally requiring sublinear space vs. a classical O(n) (linear) space requirement, and may have applications for anomaly detection of systems or networks.

For identical bosons this results in a three-dimensional integral equation in five variables, magnitudes of relative momenta and angles. The cross sections for both elastic and breakup processes in the intermediate energy range up to about 1 GeV are calculated based on a Malfliet-Tjon type potential, and the convergence of the multiple scattering series is investigated.

Can Large-Scale Migration Explain the Giant Planet Occurrence Rate?

Publisher: name: arXiv
Year: 2020
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The giant planet occurrence rate rises with orbital period out to at least $\sim$300 days. Large-scale planetary migration through the disk has long been suspected to be the physical origin of this feature, as the timescale of standard Type I migration in a standard solar nebula is longer farther from the star. These calculations also find that typical Jupiter-bearing cores shuttle towards the disk inner edge on timescales orders of magnitude shorter than the gas disk lifetime. The presence of gas giants at myriad distances requires mechanisms to slow large-scale migration. We revisit the migration paradigm by deriving model occurrence rate profiles from migration of cores, mass growth by gas accretion, and planetary gap opening. We show explicitly that the former two processes occur in tandem. Radial transport of planets can slow down significantly once deep gaps are carved out by their interaction with disk gas. Disks are more easily perturbed closer to the star, so accounting for gap opening flattens the final orbital period distribution. To recover the observed rise in occurrence rate, gas giants need to be more massive farther out, which is naturally achieved if their envelopes are dust-free. The range of mass gradients we find to reconcile the observed occurrence rate of Jupiters is too abrupt to account for the mass-period distribution of low-eccentricity giant planets, challenging disk migration as the dominant origin channel of hot and warm Jupiters. Future efforts in characterizing the unbiased mass distribution will place stronger constraints on predictions from migration theory.

On-line education: on the job training with computer conferencing (the virtual education oracle)
Creators: name: Guenther, John J.
Publisher: name: University of British Columbia
Year: 2009

description: Through the delivery of a building code education module over the internet, the effectiveness of on-line education in a work environment was examined. Building officials served as the expert facilitators and instructors and the students were architects and designers. Guests from an arm of the National Research Council involved in building code issues were also invited to take part. Thirty-nine selected students were placed in two groups (Group I and Group II) controlling for age, work experience, computer skill and knowledge of the building code. Two groups, each with about 20 students were selected to participate in an on-line computer conference. Group I received an on-line curriculum with posttests after each section and Group II received only posttests. Academic achievement comparisons were then made between the two groups. T-tests were used to compare achievement for the two groups of learners, one with an online curriculum and one without an on-line curriculum, but both given the opportunity to conference and answer specific section review or posttest questions. Dependent variables were identified as instructor access, motivation, participation levels, comparisons to the traditional classroom, level and convenience of on-line involvement, virtual classroom overall rating, course rating, instructor rating, interest, ability to synthesize ideas, academic achievement, and group communication. The independent variables were computer attitudes, expectations about the conferencing system, interpersonal sphere of control, terminal access, and curriculum design. Frequencies were compiled and displayed in graph form to portray variables. Comparisons were made using Pearson Correlations. Results indicate that: • the internet can be a valuable tool for student access and knowledge-building exercises, supporting the hypothesis that students who experience group or collaborative learning in the virtual classroom are more likely to judge the outcomes of an on-line course to be superior to the outcomes of traditional classrooms; • students who depend on their own effort rather than "luck" are more likely to regularly and actively participate on-line; • those with high viewed the on-line experience with some trepidation indicating that they would not prefer to take another on-line course; • the curriculum did not affect gains in building code knowledge between curriculum and non-curriculum groups when exposed to a computer conferencing delivery system; • the interface continues to confound students and leads to frustration that can debilitate the learning experience; and • on-the-job learning is constrained by time and work load demands.

description: Many factors, including facets of personality, contribute to alcohol-dependent individuals' ability to achieve and maintain abstinence during treatment.  This study examined the relation between trait impulsivity and abstinence self-efficacy in the prediction of drinking outcomes in two subsamples of Project MATCH participants who drank during 12 weeks of outpatient treatment: 1) individuals struggling to sustain sobriety following inpatient treatment, and 2) individuals trying to achieve sobriety after entering outpatient treatment directly.  Multiple linear regression was used to test three models during treatment in which self-efficacy mediated impulsivity's prediction of 1) the intensity of drinking, 2) the total number of drinks consumed, and 3) the associated consequences of drinking.  None of the regression analyses yielded significant relations among the variables and mediation was not supported in any of the models.  Possible reasons include issues with sample characteristics, measurement limitations, the reduction of the Project MATCH sample, and the models' underlying assumptions.

In this paper we study photon signals arising from cosmic ray (CR) electron scattering on background ALPs. For a range of masses we find that these bounds can place competitive new constraints on the ALP-electron coupling, although in many models lifetime constraints may supersede these bounds. In addition to current Fermi constraints, we also consider future e-Astrogram bounds which will have greater sensitivity to ALP-CR induced gamma-rays.

description: This study examines relapse and recovery in Project MATCH. The study examines the transitions between periods of abstinence, lapse, and relapse. A set of proximal and distal variables were hypothesized to predict the likelihood of a transition to a different state over time using a semi-Markov model. The distal variables were stable predictors of relapse including severity of addiction, drug use, and psychiatric severity. The proximal predictors, which varied over time, included anger, symptoms of depression, action, struggling with maintenance, temptation, confidence, and social support. The study examined drinking outcomes of 469 individuals post-treatment and found that confidence to abstain and action orientation increased the probability of abstinence, and decreased the probability of lapsed and relapsed drinking. Confidence and endorsing action stage behaviors and attitudes were associated with the abstinence violation effect. The constructs of temptation and struggling with maintenance acted as risk factors for higher levels of drinking. Depression had mixed effects and appeared to be related to lapsed drinking more than relapsed drinking. Alcohol involvement acted as a risk factor for relapsed drinking. Information about the individuals drinking history was also examined. The number of prior episodes in abstinence or drinking states increased the probability of returning to the same types of abstinent or drinking behaviors. The length of each episode less frequently was significantly related to the transitions,  However when significant, longer periods of abstinence and relapsed drinking were associated with less likely return to the same behaviors. Of particular note was that a history of relapsed drinking made lapsed drinking less likely, and a history of lapsed drinking made relapsed drinking less likely. This pattern supports the underlying division of drinking behaviors into the two categories of lapse and relapse. This study demonstrated that novel statistical methods such as Semi-Markov models can be used to investigate questions which could not be addressed or effectively answered with more commonly used methods. The semi-Markov models of transitions between drinking states helped to explain the complexity of the road to recovery.

description: We introduce three new mechanisms that allow trust to be built into cloud computing called the Private Virtual Infrastructure (PVI)< ic>Locator Bot (LoBot)< italic>Trusted Virtual Environment Module (TVEM)< puting requires that organizations trust that a service provider’s platforms are secured and provide a sufficient level of integrity for the client’s data. Once a client’s sensitive data are released into the cloud under the control of a third party, a significant level of risk is placed on the security and privacy of the data. PVI, LoBot, and TVEM provide a means for clients to establish trust in cloud platforms, thus reducing their risk exposure. PVI is a new management and security model that shares the responsibility of security management in cloud computing between the service provider and client, decreasing the risk exposure to both. The PVI datacenter’s security posture is set by the client, while the cloud’s configuration is under control of the service provider. Clients can then protect their information independently of the cloud configuration. The LoBot pre-measures the cloud for security properties which can be used to determine the integrity and trustworthiness of the destination platform. LoBot then provides secure provisioning and live migration for the virtual datacenter. LoBot protects information by preventing data from being placed in malicious environments. The TVEM helps solve the core se curity challenge of cloud computing by establishing trust in a virtualized cloud computing environment. The TVEM is a software appliance that merges trust from multiple sources, typically the information owner and service provider, to derive a root of trust for a virtual environment on a remote host. A unique Trusted Environment Key (TEK)< rust from the information owner and the service provider to create a dual root of trust for the TVEM that is distinct for every virtual environment and separate from the host platform’s trust. PVI, Locator Bot, and TVEM can be used individually or combined to provide a foundation for trust in cloud computing. They enable organizations to maintain control of their information in the cloud and realize benefits of cloud computing.

A topologically-derived dislocation theory for twist and stretch moiré superlattices in bilayer graphene

description: We develop a continuum dislocation description of twist and stretch moire superlattices in 2D material bilayers. The continuum formulation is based on the topological constraints introduced by the periodic dislocation network associated with the moire structure. The approach is based on solving analytically for the structural distortion and displacement fields that satisfy the topological constraints, and which minimize the total energy. The total energy is described by both the strain energy of each individual distorted layer, and a Peierls-Nabarro like interfacial contribution arising from stacking disregistry. The dislocation core emerges naturally within the formalism as a result of the competition between the two contributions. The approach presented here captures the structure and energetics of twist and stretch moire superlattices of dislocations with arbitrary direction and character, without assuming an analytical solution a priori, with no adjustable parameters, while accounting naturally for dislocation-dislocation image interactions. In comparisons to atomistic simulations using classical potentials, the maximum structure deviation is 6%, while the maximum line energy deviation is 0.019 eV/Angstrom. Several applications of our model are shown, including predicting the variation of structure with twist angle, and describing dislocation line tension and junction energies.

description: There are limited studies on the semantic segmentation of high-resolution Polarimetric Synthetic Aperture Radar (PolSAR) images due to the scarcity of training data and the inference of speckle noises. The Gaofen contest has provided open access of a high-quality PolSAR semantic segmentation dataset. Taking this chance, we propose a Multi-path ResNet (MP-ResNet) architecture for the semantic segmentation of high-resolution PolSAR images. Compared to conventional U-shape encoder-decoder convolutional neural network (CNN) architectures, the MP-ResNet learns semantic context with its parallel multi-scale branches, which greatly enlarges its valid receptive fields and improves the embedding of local discriminative features. In addition, MP-ResNet adopts a multi-level feature fusion design in its decoder to make the best use of the features learned from its different branches. Ablation studies show that the MPResNet has significant advantages over its baseline method (FCN with ResNet34). It also surpasses several classic state-of-the-art methods in terms of overall accuracy (OA), mean F1 and fwIoU, whereas its computational costs are not much increased. This CNN architecture can be used as a baseline method for future studies on the semantic segmentation of PolSAR images. The code is available at: https://github.com/ggsDing/SARSeg.

description: We extend the framework of modular invariant supersymmetric theories to encompass invariance under more general discrete groups $Γ$, that allow the presence of several moduli and make connection with the theory of automorphic forms. Moduli span a coset space $G/K$, where $G$ is a Lie group and $K$ is a compact subgroup of $G$, modded out by $Γ$. For a general choice of $G$, $K$, $Γ$ and a generic matter content, we explicitly construct a minimal Kähler potential and a general superpotential, for both rigid and local $N=1$ supersymmetric theories. We also specialize our construction to the case $G=Sp(2g,R)$, $K=U(g)$ and $Γ=Sp(2g,Z)$, whose automorphic forms are Siegel modular forms. We show how our general theory can be consistently restricted to multi-dimensional regions of the moduli space enjoying residual symmetries. After choosing $g=2$, we present several examples of models for lepton and quark masses where Yukawa couplings are Siegel modular forms of level 2.

description: Enzymatic inhibition of biological methylation pathways essential for viral and cancer replication has shown promise in the design of new chemotherapeutics. Disruption of the action of critical enzymes such as S-adenosyl-L-homocystine hydrolase (SAHase), and DNA methyltransferases (DNMT) has been shown to affect viral and tumor cell replication. In that regard, carbocyclic nucleoside derivatives, as a class, have shown potent inhibitory activity in both areas. Carbocyclic nucleosides are structurally modified such that they mimic the natural nucleosides enough to be recognized, but ultimately have the ability to disrupt subsequent biological processes. Aristeromycin and neplanocin are two of the naturally occuring carbocyclic nucleosides that showed potent inhibitory activity against SAHase, and as a result exhibit potent antiviral activity against several viruses. These nucleoside analogues, however, suffer from cytotoxicity and several other side effects.  As part of our ongoing research on new nucleoside analogues with potential antiviral and anticancer activities, we have synthesized a new series of purine-pyrimidine hybrid carbocyclic isonucleoside analogues as inhibitors of SAHase. The novel nucleosides have been evaluated for their antiviral and anticancer properties. We have also synthesized truncated thymidine analogues and they have been evaluated for their inhibitory activity against SAHase and DNMT. One of the analogues has shown 95.8% inhibition of Hepatitis C virus (HCV) at a concentration of 20 ?M and is undergoing further testing. Also, the truncated nucleoside analogue inhibits SAHase (Ki< esign and synthesis of this new series of nucleoside analogues will be discussed.

Time, art and resistance: visual art programs in prisons

description: The following study evolved out of a pilot study which I conducted in the summer of 1995 at a correctional facility in eastern Ontario. The testimony of two volunteer inmates there led me to the present enquiry: How do inmates experience time, what are their perceptions of it, and to what extent art making has any impact on those perceptions? Using the temporal theories of two sociologists, Edward Hall (1983) and Victor Gioscia (1971), which I illustrated through relevant literary works concerning inmates of long-term institutions, I sought evidence of alternative temporal constructs in the behavior and testimonies of the volunteer inmates. The twelve week case study involved setting up a course of art similar to the one offered in 1995. This one took place in a medium security correctional facility for men in the lower mainland of British Columbia, during the summer of 1996. Unlike the pilot study, which operated during regular school time, the latter study was held during inmates' leisure time, two evenings a week, for three hours each evening. The following ethnographic methods of data collection were used: pre-program questionnaires, field notes, interviews, and document analysis. Thirteen men originally participated in the art course, of whom, six agreed to be interviewed. Because the art course was canceled midway through my research, I reconsidered my study, my double role as researcher-teacher, and the data that I had so far collected, to ponder the dynamics of research and volunteer programs within the prison bureaucracy. Evidence of Hall's temporal notions was scant; however, some of the inmates interviewed indicated negative effects of long-term incarceration that corresponded to Gioscia's definitions; these men also demonstrated resistance mechanisms through the practice and mentoring of art and hobbies. As well, prison staff, particularly administrators, are implicated in the failure of volunteer/adult education program delivery. Closing reflections support participatory strategies in qualitative research in the light of postmodern research theory and end with practical and theoretical recommendations.

description: There is considerable interest in the use of genetic algorithms to solve problems arising in the areas of scheduling and timetabling. However, the classical genetic algorithm paradigm is not well equipped to handle the conflict between objectives and constraints that typically occurs in such problems. In order to overcome this, successful implementations frequently make use of problem specific knowledge. This paper is concerned with the development of a GA for a nurse rostering problem at a major UK hospital. The structure of the constraints is used as the basis for a co-evolutionary strategy using co-operating sub-populations. Problem specific knowledge is also used to define a system of incentives and disincentives, and a complementary mutation operator. Empirical results based on 52 weeks of live data show how these features are able to improve an unsuccessful canonical GA to the point where it is able to provide a practical solution to the problem

description: Hardware manufacturers are increasingly outsourcing their Integrated Circuits (IC) fabrication to offshore facilities, due to the global economic business pressures. These facilities are geographically dispersed and are typically outside the control of known trusted sources, which makes the ICs vulnerable to malicious modi?cations. Adversaries can modify the systems to circumvent the security and encryption, trigger based on certain data patterns, and incapacitate critical systems like radar at crucial times. The malicious alterations and inclusions made by adversaries to the IC during fabrication are known as Trojans.There is a considerable interest in the academic community to develop Trojan detection methods. But, currently there are no benchmark designs to evaluate, compare and contrast these different Trojan detection methods. In this work, a design ?ow known as the Iterative Restrictive and Replacement (IRR) technique was developed to design and build small-to-large benchmark physical layouts for Trojan-based insertion and detection experiments. The IRR technique was successfully applied to build a medium-to-large benchmark design. This design is based on a 5-stage pipelined MIPS microprocessor and incorporates Design For Hardware Trust (DFHT) support for Rad et al. [10] proposed power supply transient signal analysis method to detect defects, and host Trojans at various locations in the IC. Further work could involve developing more benchmark circuits, fabrication and validation in silicon.
