description: Developers always wish to ensure that their latest changes to the code base do not break existing functionality. If test cases fail, they expect these failures to be connected to the submitted changes. Unfortunately, a flaky test can be the reason for a test failure. Developers spend time to relate possible test failures to the submitted changes only to find out that the cause for these failures is test flakiness. The dilemma of an identification of the real failures or flaky test failures affects developers' perceptions about what is test flakiness. Prior research on test flakiness has been limited to test smells and tools to detect test flakiness. In this paper, we have conducted a multiple case study with four different industries in Scandinavia to understand practitioners' perceptions about test flakiness and how this varies between industries. We observed that there are little differences in how the practitioners perceive test flakiness. We identified 23 factors that are perceived to affect test flakiness. These perceived factors are categorized as 1) Software test quality, 2) Software Quality, 3) Actual Flaky test and 4) Company-specific factors. We have studied the nature of effects such as whether factors increase, decrease or affect the ability to detect test flakiness. We validated our findings with different participants of the 4 companies to avoid biases. The average agreement rate of the identified factors and their effects are 86% and 86% respectively, among participants.

description: This thesis examined the patterns, predictors, and outcomes related to prescription opioid use. Approximately 3 million adults use opioids and over 1.9 million adults initiate opioids in Australia each year. By extrapolation, 50,000 adults take opioids long-term and over 26,000 use high doses. At a population level, opioid initiation was not related to a change in the pattern of work disability. Complex patterns of opioid use on an individual and population level identified in this thesis suggest that large coordinated infrastructures and champions at the national, state and local levels are required to address opioid-related harm in Australia.

description: In Nigeria, human trafficking is a hidden crime, driven by the current economic situation of the country. The Nigerian government has demonstrated significant efforts to combating human trafficking in the country by creating the National Agency for the Prohibition of Trafficking in Persons (NAPTIP). The incidents of human trafficking in the Nigeria’s oil-producing communities have remained among the highest in the country and higher than the national average. The objective of this investigation was to determine the impact of a new corporate social responsibility (CSR) model of multinational oil companies (MOCs) on the fight against human trafficking in the host communities. A total of one thousand, two hundred households were sampled across the rural communities of Niger Delta. Results from the use of a combined propensity score matching and logit model indicated that MOCs hold the key to combating human trafficking by fostering effective partnership across different sectors, if the highest CSR priority is assigned to reducing incidents of human trafficking in the oil-producing communities. Embracing the fight against human trafficking should form the foundation of General Memorandum of Understanding (GMoUs) practice, which in turn will provide the enabling environment for more widespread responsible business. As most of the human trafficking in the Niger Delta is exploited by relatives or friends; MOCs should involve traditional and religious leaders in the fight and set up GMoU clusters interventions specifically for anti-trafficking agencies including NAPTIP, the police and immigration to support their actions and improve efficiency.

description: In this work we derive the Hamiltonian formalism of the O(N) non-linear sigma model in its original version as a second-class constrained field theory and then as a first-class constrained field theory. We treat the model as a second-class constrained field theory by two different methods: the unconstrained and the Dirac second-class formalisms. We show that the Hamiltonians for all these versions of the model are equivalent. Then, for a particular factor-ordering choice, we write the functional Schrodinger equation for each derived Hamiltonian. We show that they are all identical which justifies our factor-ordering choice and opens the way for a future quantization of the model via the functional Schrodinger representation.

description: The ratio of the CKM quark-mixing matrix elements |Vub|/|Vcb| has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M_X of the secondary hadronic system produced in association with an identified lepton. Since B -> X_u lepton anti-nu transitions are characterised by hadronic masses below those of the D mesons produced in B -> X_c lepton anti-nu transitions, events with a reconstructed value of M_X significantly below the D mass are selected. Further signal enrichments are obtained using the topology of reconstructed decays and hadron identification. A fit to the numbers of decays in the b -> u enriched and depleted samples with M_X above and below 1.6 GeV/c^2 and to the shapes of the lepton energy distribution in the B rest frame gives |Vub|/|Vcb|= 0.103^{+0.011}_{-0.012} (stat.) +/- 0.016 (syst.) +/- 0.010 (model) and, correspondingly, a charmless semileptonic B decay branching fraction of BR(B -> X_u lepton anti-nu) = (1.57 +/- 0.35 (stat.) +/- 0.48 (syst.) +/- 0.27 (model)) x 10^{-3}.

description: Many studies show that interaction with extension services impact farmer’s technology adoption decisions and profitability levels. However, analysis of extension impact across all farm systems whilst controlling for endogeneity biases is less common. This research attempts to redress that research gap by firstly discussing the various biases related to the motivation to engage with extension services, omitted variable bias and measurement error, and subsequently applying instrumental variable (IV) regression estimation to the relationship between extension engagement and farm level outcomes, namely family farm income over a pooled panel dataset. Distance to the local advisory office and the introduction of a policy change were chosen as valid and relevant instruments. The results indicate a positive impact of extension engagement on farm income, and imply that an ordinary least squares approach underestimates the benefits of extension engagement. Accordingly, increased advisory activity could improve the performance of the sector significantly, and this could be a useful policy tool to achieve the targets as set out by the Irish governments Food Wise 2025 plan.

All these models show glassy behavior and coarsening. We apply to them the Stillinger and Weber decomposition, and find that they share the same configurational entropy, despite of their different nonequilibrium dynamics. We conclude therefore that the Stillinger and Weber decomposition is not relevant for this type of models.

description: This paper, using Ireland as a case study, examines the relationship between economic activities and river water quality. The stipulation from the EU water framework directive (WFD) that all surface waters in the EU must be of ‘good ecological status’ by 2015 necessitate a quantitative understanding of the major determinants of water quality. Within this context, this paper combines a number of spatial datasets relating to agricultural, residential and industrial activities as well as the level of forest cover to examine the major economic influences on the ecological quality of water resources. It is hoped that providing a comprehensive understanding of the effect of a variety of economic activities that influence the ecological quality of water will be an important tool in the management of risk and will allow for more appropriate land use planning aimed at restoring and maintaining water quality as required by the WFD. Results indicate that the level of forestry, industrial activity, the intensity and type of agricultural activity and the type of wastewater treatment in an area are all critical factors affecting the quality of our water resources. Moreover, the results highlight the importance of a spatial dimension to any analysis as the principal factors affecting water quality often differ across river catchments.

title: Day Service Culture From The Perspective Of Autistic Adults With Profound Learning Disabilities: A Methodological Development And Empirical Study In The Space Of Autism And Profound Learning Disability
Creators: name: Redmore, Ned
Publisher: name: The Open University
Year: 2021

description: The primary purpose of this thesis is to explicate day service culture from the perspective of autistic people with profound learning disabilities. This includes their involvement in, and experience of, day service culture. Although other people such as support workers and autistic people without profound learning disabilities are also a significant part of day service culture, their perspectives were not the primary concern of this thesis. A review of the literature on service culture suggested that autistic people with profound learning disabilities shape and experience culture within the context of everyday life at day services, though it also recognised that there was minimal understanding of how to research such a topic. Therefore, a secondary aim was established: to detail a methodological approach that is ethically justified for researching the everyday experiences of autistic people with profound learning disabilities. This aim was initially addressed through a critical examination of what researchers mean when using the terms ‘autism’ and ‘severe/profound learning disability’ in relation to people with complex needs. It concluded that it is both epistemically and ethically unjustified to separate the terms when developing research, as this exacerbates the marginalised position of related people within academic and political domains. Subsequently, an academic space of ‘autism and profound learning disability’ is conceptualised using the phenomenological concept of life-conditions (Kraus, 2015) that recognises the shared material and immaterial circumstances of people with complex needs. A contribution to this space is made: an inclusive, lifeworld fractions approach (Ashworth, 2016) that can enable researchers to adapt studies in line with participants’ perspectives and circumstances. This approach was subsequently used within a research study that addressed the initial aim of the thesis, through an investigation into the culture of a day service for autistic adults from the everyday, lifeworld perspective of ‘Ben’, an autistic adult with profound learning disabilities. The findings show everyday life to be guided by rich spatial and temporal customs that have developed over time through the pursuits and efforts of Ben and his peers. Those traditionally referred to as service users had created a community with rules and values that were congruent with their lifestyles and characters. These findings are indicative of the contributions that autistic people with profound learning disabilities make to the service cultures that they are part of, and demonstrates some of the ways in which they realise autonomy and independence in adulthood.

description: We perform a comprehensive study of the Higgs sector of the Minimal Supersymmetric extension of the Standard Model in the case where all Higgs bosons are rather light, with masses of ${\cal O}(100 GeV)$, and couple maximally to electroweak gauge bosons and strongly to standard third generation fermions, i.e. for large values of the ratio of the vacuum expectation values of the two Higgs doublet fields, $\tan β$. We first summarize the main phenomenological features of this "intense-coupling" scenario and discuss the available constraints from direct searches of Higgs bosons at LEP2 and the Tevatron as well as the indirect constraints from precision measurements such as the $ρ$ parameter, the $Zb\bar{b}$ vertex, the muon $(g-2)$ and the decay $b\to s γ$. We then analyze the decay branching fractions of the neutral Higgs particles in this regime and their production cross sections at the upcoming colliders, the Tevatron Run II, the LHC, a 500 GeV $e^+e^-$ linear collider (in the $e^+e^-$ and $γγ$ options) as well as at a $μ^+ μ^-$ collider.

description: When a feed-forward neural network (FNN) is trained for source ranging in an ocean waveguide, it is difficult evaluating the range accuracy of the FNN on unlabeled test data. A fitting-based early stopping (FEAST) method is introduced to evaluate the range error of the FNN on test data where the distance of source is unknown. Based on FEAST, when the evaluated range error of the FNN reaches the minimum on test data, stopping training, which will help to improve the ranging accuracy of the FNN on the test data. The FEAST is demonstrated on simulated and experimental data.

description: RT-qPCR has been widely used for gene expression analysis in recent years. The accuracy of this technique largely depends on the selection of suitable reference genes. In order to facilitate gene expression analysis in wild and cultivated Cannabis, the expression stability of seven candidate reference genes (ACT2, 18S rRNA, GAPDH, UBQ, TUB, PP2A and EF1α) were assessed in leaves samples of different development stages and different organs of both wild and cultivated Cannabis in the present study. Their expression stabilities were evaluated through three software packages (GeNorm, Normfinder and Bestkeeper). Results showed that UBQ and EF1α were the highly ranked genes in different leaves samples, and PP2A was the most stable reference gene in different organs, while GAPDH was the least stable one. And the validation of the reference genes selected was further confirmed by the expression patterns of MDS and OLS. Expression levels of 7 reference genes in Cannabis, presented as mean value of Ct in all 20 conditions. Ct values are the average of three replicates.

The results indicate that Thailand will benefit most from an expansion of imports of luxury rice and broken rice products. Vietnam will gain from growth in the market for standard rice. The results also suggest that adoption of a new 35 percent tariff policy to protect the domestic industry will not be enough to improve social welfare in Côte d’Ivoire in spite of increased production value.
Brane cosmology, varying speed of light and inflation in models with one or more extra dimensions

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We summarise the approach to brane cosmology known as ``mirage cosmology'' and use it to determine the Friedmann equation on a 3-brane embedded in different bulk spacetimes all with one or more extra dimensions. Usually, when there is more than one extra dimension the junction conditions, central to the usual brane world scenarios, are difficult to apply. This problem does not arise in mirage cosmology because the brane is treated as a ``test particle'' in the background spacetime. We discuss in detail the dynamics of a brane embedded in two specific 10D bulk spacetimes, namely Sch-AdS$_5 \times$S$_5$ and a rotating black hole, and from the dynamics--which are now rather more complicated since the brane can move in all the extra dimensions--determine the new ``dark fluid'' terms in the brane Friedmann equation. Some of these, such as the cosmological constant term, are seen to be bulk dependent. However, for both bulks we show that there exists a critical brane angular momentum, $\ell_c$, and discuss its significance. We then show explicitly how this mirage cosmology approach matches with the familiar junction condition approach when there is just one extra dimension. The issue of a varying speed of light in mirage cosmology is reviewed and we find a scenario in which $c_{\bf eff}$ always increases, tending asymptotically to a constant $c_0$ as the universe expands. Finally some comments are made regarding brane inflation and limitations of the mirage cosmology approach are also discussed.

description: The small Indian mongoose is among the worst of invasive alien species, yet the implications of managing the species are poorly understood. To address concerns of interest to practitioners and policymakers, we analyze survey data to document the impacts of this species in Fiji and conduct a cost-benefit analysis of management approaches that are both culturally appropriate and readily implementable: live trapping, kill trapping, and hunting. We find that the monetized benefits of kill trapping exceed the benefits of live trapping and hunting. Still, all of these management options are preferred to the status quo of no management.

description: Program outreach activities are integral components of social welfare programs, but the relationship between availability of outreach services and households’ program participation has not been examined due to lack of data on outreach efforts. This study uses a unique, nationally representative, matched household-agency data set of more than 21,000 households from 2009 to examine relationships between household participation in the Supplemental Nutrition Assistance Program (SNAP) and outreach and eligibility services offered by local agencies. When agencies provide applications to clients of emergency food pantries and submit their applications to SNAP administrative of􀏐ices, the probability of household participation in SNAP increases 5–6 percentage points.

description: The magnetic field is believed to play an important role in at least some core-collapse supernovae if its magnitude reaches $10^{15}\,\rm{G}$, which is a typical value for a magnetar. In the presence of fast rotation, such a strong magnetic field can drive powerful jet-like explosions if it has the large-scale coherence of a dipole. The topology of the magnetic field is, however, probably much more complex with strong multipolar and small-scale components and the consequences for the explosion are so far unclear. We investigate the effects of the magnetic field topology on the dynamics of core-collapse supernovae and the properties of forming proto-neutron star (PNS) by comparing pre-collapse fields of different multipolar orders and radial profiles. Using axisymmetric special relativistic MHD simulations and a two-moment neutrino transport, we find that higher multipolar magnetic configurations lead to generally less energetic explosions, slower expanding shocks and less collimated outflows. Models with a low order multipolar configuration tend to produce more oblate PNS, surrounded in some cases by a rotationally supported toroidal structure of neutron-rich material. Moreover, magnetic fields which are distributed on smaller angular scales produce more massive and faster rotating central PNS, suggesting that higher-order multipolar configurations tend to decrease the efficiency of the magnetorotational launching mechanism. Even if our dipolar models systematically display a far more efficient extraction of the rotational energy of the PNS, fields distributed on smaller angular scales are still capable of powering magnetorotational explosions and shape the evolution of the central compact object.

description: When a solid substrate is withdrawn from a bath of simple, partially wetting, nonvolatile liquid, one typically distinguishes two regimes, namely, after withdrawal the substrate is macroscopically dry or homogeneously coated by a liquid film. In the latter case, the coating is called a Landau-Levich film. Its thickness depends on the angle and velocity of substrate withdrawal. We predict by means of a numerical and analytical investigation of a hydrodynamic thin-film model the existence of a third regime. It consists of the deposition of a regular pattern of liquid ridges oriented parallel to the meniscus. We establish that the mechanism of the underlying meniscus instability originates from competing film dewetting and Landau-Levich film deposition. Our analysis combines a marginal stability analysis, numerical time simulations and a numerical bifurcation study via path-continuation.

description: Data from H1 and ZEUS on the structure and the quark and gluon densities of the proton are discussed. A brief excursion is made into the field of inclusive diffraction by deep inelastic scattering. The comparison of e- p and e+ p scattering at large momentum transfers demonstrates clearly the presence of weak contributions in neutral current interactions. The comparison with the corresponding charged current results shows at Q2 values above the masses squared of the heavy vector bosons the unification of electromagnetic and weak interactions. The new data are testing the validity of the Standard Model down to spatial resolutions of the order of 10^{-16} cm. Intensive searches have been performed for a manifestation of instantons, for signs of compositeness of quarks and leptons and for the effect of extra dimensions.

description: A database on mechanistic characteristics of human carcinogenic agents was developed by collecting mechanistic information on agents identified as human carcinogens (Group 1) by the International Agency for Research on Cancer (IARC) in the IARC Monographs on the Evaluation of Carcinogenic Risks to Humans. A two-phase process is described for the construction of the database according to 24 toxicological endpoints, derived from appropriate test systems that were acquired from data obtained from the mechanisms sections of the IARC Monographs (Section 4) and a supplementary PubMed search. These endpoints were then aligned with 10 key characteristics of human carcinogens that reflect the broader attributes of these agents relating to the development of cancer in humans. The considerations involved in linking of toxicological endpoints to key characteristics are described and specific examples of the determination of key characteristics for six specific agents (tamoxifen, hepatitis B virus, arsenic, ultraviolet and solar radiation, tobacco smoking, and dioxin) are provided. Data for humans and animals were tabulated separately, as were results for in-vivo and for in-vitro sources of information. The database was constructed to support a separate analysis of the expression of these endpoints by 86 Group 1 carcinogens, in-vivo and in-vitro along with an analysis of the key characteristics of these agents.

description: Abstract: Metacognitive abilities allow us to adjust ongoing behavior and modify future decisions in the absence of external feedback. Although metacognition is critical in many daily life settings, it remains unclear what information is actually being monitored and what kind of information is being used for metacognitive decisions. In the present study, we investigated whether response information connected to perceptual events contribute to metacognitive decision-making. Therefore, we recorded EEG signals during a perceptual color discrimination task while participants were asked to provide an estimate about the quality of their decision on each trial. Critically, the moment participants provided their confidence judgments varied across conditions, thereby changing the amount of action information (e.g., response competition or response fluency) available for metacognitive decisions. Results from three experiments demonstrate that metacognitive performance improved when first-order action information was available at the moment metacognitive decisions about the perceptual task had to be provided. This behavioral effect was accompanied by enhanced functional connectivity (beta phase synchrony) between motor areas and prefrontal regions, exclusively observed during metacognitive decision-making. Our findings demonstrate that action information contributes to metacognitive decision-making, thereby painting a picture of metacognition as a process that integrates sensory evidence and information about our interactions with the world.
Searching for z ~ 6 Objects with the HST Advanced Camera for Surveys: Preliminary Analysis of a Deep Parallel Field

description: Recent results suggest that z ~ 6 marks the end of the reionization era. A large sample of objects at z ~ 6, therefore, will be of enormous importance, as it will enable us to observationally determine the exact epoch of the reionization and the sources that are responsible for it. With the HST Advanced Camera for Surveys (ACS) coming on line, we now have an unique opportunity to discover a significant number of objects at z ~ 6. The pure parallel mode implemented for the Wide Field Camera (WFC) has greatly enhanced this ability. We present our preliminary analysis of a deep ACS/WFC parallel field at |b|=74.4^o. We find 30 plausible z ~ 6 candidates, all of which have S/N > 7 in the F850LP-band. The major source of contamination could be faint Galactic cool dwarfs, and we estimated that they would contribute at most 4 objects to our candidate list. We derived the cumulative number density of galaxies at 6.0 <= z <= 6.5 as 2.3 arcmin^{-2} to a limit of 28.0 mag in the F850LP-band, which is slightly higher than our prediction. If this is not due to an underestimated contamination rate, it could possibly imply that the faint-end slope of the z ~ 6 luminosity function is steeper than alpha=-1.6. At the very least, our result suggests that galaxies with L

description: Scattering amplitudes in quantum field theories are of widespread interest, due to a large number of theoretical and phenomenological applications. Much is known about the possible behaviour of amplitudes, that is independent of the details of the underlying theory. This knowledge is often neglected in modern QFT courses, and the aim of these notes - aimed at graduate students - is to redress this. We review the possible singularities that amplitudes can have, before examining the generic behaviour that can arise in the high-energy limit. Finally, we illustrate the results using examples from QCD and gravity.

description: The authors present an analytical model of a first-price sealed-bid cattle auction in which a spot and coordinated markets are interconnected. The model reveals that the conventional wisdom that market coordination negatively affects the bid price in the spot market is an oversimplification. The relationships between key market variables impact bids and bid shading in complex ways. While captive supplies can lead to lower spot prices, the price reductions do not necessarily stem from an increase in market power due to contracting. The model emphasizes the importance of several variables for future empirical studies.

description: We present first-principles calculations of optimally localized Wannier functions for Cu and use these for an ab-initio determination of Hubbard (Coulomb) matrix elements. We use a standard linearized muffin-tin orbital calculation in the atomic-sphere approximation (LMTO-ASA) to calculate Bloch functions, and from these determine maximally localized Wannier functions using a method proposed by Marzari and Vanderbilt. The resulting functions were highly localized, with greater than 89% of the norm of the function within the central site for the occupied Wannier states. Two methods for calculating Coulomb matrix elements from Wannier functions are presented and applied to fcc Cu. For the unscreened on-site Hubbard $U$ for the Cu 3d-bands we have obtained about 25eV. These results are also compared with results obtained from a constrained local-density approximation (LDA) calculation.

description: A novel adsorbent, poly(sodium 4–styrenesulfonate) modified MIL-101(Cr)–NH2, was successfully prepared. Owing to its high surface area and degree of negative surface charge, it enables effective adsorption and separation of illegal cationic dyes, such as rhodamine B, pararosaniline, and auramine O, from foodstuffs prior to high performance liquid chromatography analysis. Under optimised conditions, good linearity was obtained over 1.0–80.0 or 1.0–120 ng mL−1 with a correlation coefficient (R2) > 0.999. Limits of detection and limits of quantification of the three dyes were 0.28–0.65 and 0.94–2.13 μg kg−1, respectively. The recoveries of the three dyes in shrimp powder, chili powder, tofu sheets, and tomato sauce were in the range of 86.8–119.3%, suggesting that the developed method is a promising tool for accurate quantification of the three dyes at trace levels in foodstuffs.

description: We study the fate of U(1) strings embedded in a non-Abelian gauge theory with a hierarchical pattern of the symmetry breaking: G->U(1) at V->nothing at v, V>>v. While in the low-energy limit the Abrikosov-Nielsen-Olesen string (flux tube) is perfectly stable, being considered in the full theory it is metastable. We consider the simplest example: the magnetic flux tubes in the SU(2) gauge theory with adjoint and fundamental scalars. First, the adjoint scalar develops a vacuum expectation value V breaking SU(2) down to U(1). Then, at a much lower scale, the fundamental scalar (quark) develops a vacuum expectation value v creating the Abrikosov-Nielsen-Olesen string. (We also consider an alternative scenario in which the second breaking, U(1)->nothing, is due to an adjoint field.) We suggest an illustrative ansatz describing an "unwinding" in SU(2) of the winding inherent to the Abrikosov-Nielsen-Olesen strings in U(1). This ansatz determines an effective 2D theory for the unstable mode on the string world-sheet. We calculate the decay rate (per unit length of the string) in this ansatz and then derive a general formula. The decay rate is exponentially suppressed. The suppressing exponent is proportional to the ratio of the monopole mass squared to the string tension, which is quite natural in view of the string breaking through the monopole-antimonopole pair production. We compare our result with the one given by Schwinger's formula dualized for describing the monopole-antimonopole pair production in the magnetic field.
