Reliability and validity of the career decision-making difficulties questionnaire
Creators: name: Arnold, Renata
Publisher: name: University of British Columbia
Year: 2009

description: The Career Decision-Making Difficulties Questionnaire (CDDQ; Gati, Krausz, & Osipow, 1996) is a relatively new career inventory which purports to measure all areas of problems related to career decision making. This purported ability to identify specific features relating to the individual's career decision making difficulties indicates that the CDDQ may have the potential to be a significant new tool for the career counseling process. This study assessed the reliability and convergent and discriminant validity of the CDDQ on a Canadian population. The sample included 139 Kwantlen University College students. Discriminant validity was assessed using a measure of anxiety, the STAI. Convergent validity was assessed using a measure of career self-efficacy, the CDSE-SF. As hypothesized, the correlation between the CDDQ and the CDSE-SF was negative (-.60). However, contrary to the expectation that the measure for discriminant validity would show a considerably weaker correlation with the CDDQ than the measure for convergent validity, the study found positive correlations between the CDDQ and the State sub-scale of the STAI at .48, and with the Trait sub-scales at.52. The statistically significant relationship between the CDDQ and the STAI-S and STAI-T indicates the CDDQ was affected by state and trait anxiety. The implications of the findings for the future use of this measure for the Canadian career counseling process are discussed.

description: We investigate the effect of local electron correlations on transport through parallel quantum dots. The linear conductance as a function of gate voltage is strongly affected by the interplay of the interaction U and quantum interference. We find a pair of novel correlation induced resonances separated by an energy scale that depends exponentially on U. The effect is robust against a small detuning of the dot energy levels and occurs for arbitrary generic tunnel couplings. It should be observable in experiments on the basis of presently existing double-dot setups.

description: The objective is to identify significant determinants of performance for food processing firms over the 1992 to 2003 time period, focusing particularly on the issue of family control. Variables measuring firm effects such as asset size, governance, income distribution, and risk are used to explain return on equity. This study builds upon previous research by including a measure of income distribution in the food processing industry. Governance variables are found to be significant determinants of return on equity. The results found no evidence of agency problems in family-controlled firms during this time period.

description: Zoning decisions related to residential lot size and density affect residential land value. Effects of size on residential parcel value in Roanoke County, VA, are estimated with fixed effects hedonic models. Parcel size; elevation; soil permeability; proximity to urban areas, malls, and roads; and location influence parcel value, but the effects vary by value of construction and development status. Parcel value per square meter declines with increasing parcel size. The estimated relationships could be used to evaluate zoning decisions in terms of land values and tax revenues if model estimation uncertainties and responses by developers to zoning strategies are considered.
Dipoles and streams in two-dimensional turbulence

description: Following the suggestion from the Monte--Carlo experiments in Jiménez, J. of Turbul. 2020), that dipoles are as important to the dynamics of decaying two-dimensional turbulence as individual vortex cores, it is found that the kinetic energy of this flow is carried by elongated streams formed by the concatenation of dipoles. Vortices separate into a family of small fast-moving cores, and another family of larger slowly moving ones, which can be described as `frozen' into a slowly evolving `crystal'. The kinematics of both families are very different, and only the former is self-similar. The latter is responsible for most of the kinetic energy of the flow, and its vortices form the dipoles and the streams. Mechanisms are discussed for the growth of this slow component.

description: In this study we apply a spatial conditional logit model to determine factors influencing land cover change in three contiguous counties in West Georgia between 1992 and 2001 using point (pixel) based observations of land characteristics. We found that accessibility to population and population growth affect not only development of rural lands and transition between agricultural and forestry uses, but also influence changes between forest types. The model could be used to project land use–land cover change at watershed or subwatershed level and thus serve as a valuable tool for county and city planners.
D3.2 - Report on existing domain ontologies in identified domains

description: OntoCommons aims at defining a semantic interoperability framework to support the documentation of industrial data with ontologies. This document summarizes the landscape analysis on domain ontologies performed in T3.2 of the project. The scope of this analysis covers the domains of Physics and Chemistry, Mechanical and Industrial Engineering, Materials Science and Engineering, Thermal and process engineering and Computer Science, Systems and Electrical Engineering.A dataset of 130 ontologies has been created based on expert inputs collected during workshops and surveys. Using this dataset, we collected several information both manually and automatically to better describe the landscape (number of ontologies by domains, usage of Top-Level Ontologies, serialization, complexity, and a compliance to the FAIR principles, domain coverage,…).This first analysis highlighted the strong heterogeneities within and among the different domains and the low level of compliance to the FAIR principles for each community. This report provides a snapshot of our work which will be pursued during the project.
Distilling Programs to Prove Termination

description: The problem of determining whether or not any program terminates was shown to be undecidable by Turing, but recent advances in the area have allowed this information to be determined for a large class of programs. The classic method for deciding whether a program terminates dates back to Turing himself and involves finding a ranking function that maps a program state to a well-order, and then proving that the result of this function decreases for every possible program transition. More recent approaches to proving termination have involved moving away from the search for a single ranking function and toward a search for a set of ranking functions; this set is a choice of ranking functions and a disjunctive termination argument is used. In this paper, we describe a new technique for determining whether programs terminate. Our technique is applied to the output of the distillation program transformation that converts programs into a simplified form called distilled form. Programs in distilled form are converted into a corresponding labelled transition system and termination can be demonstrated by showing that all possible infinite traces through this labelled transition system would result in an infinite descent of well-founded data values. We demonstrate our technique on a number of examples, and compare it to previous work.

We Apply this result to the case where the weak perturbing potential is the back-action of a measuring device (i.e. a protective measurement). It is shown that under these conditions, most trajectories never cross the position measured (as already shown for a particular example in [3]).

description: The MIT/IEEE/Amazon GraphChallenge.org encourages community approaches to developing new solutions for analyzing graphs and sparse data. Sparse AI analytics present unique scalability difficulties. The Sparse Deep Neural Network (DNN) Challenge draws upon prior challenges from machine learning, high performance computing, and visual analytics to create a challenge that is reflective of emerging sparse AI systems. The sparse DNN challenge is based on a mathematically well-defined DNN inference computation and can be implemented in any programming environment. In 2019 several sparse DNN challenge submissions were received from a wide range of authors and organizations. This paper presents a performance analysis of the best performers of these submissions. These submissions show that their state-of-the-art sparse DNN execution time, $T_{\rm DNN}$, is a strong function of the number of DNN operations performed, $N_{\rm op}$. The sparse DNN challenge provides a clear picture of current sparse DNN systems and underscores the need for new innovations to achieve high performance on very large sparse DNNs.

description: The organizers of this symposium invited me to address the topic of evaluation as related to rural development and/or small farms. I will discuss evaluation of a small but important aspect of the former and disregard the latter. Specifically, I will not discuss the area of small farms. Rather, I will simply refer to a forthcoming report which evaluates the state of past research on small farms and proposes an agenda for future research (Madden, et al, 1980). I will however, discuss the evaluation of a specific type of rural development research-extension program conducted by the land-grant university system, namely, Title V of the Rural Development Act of 1972. Beyond the scope of this paper is the recent USDA evaluation of cooperative research, including community resource development and other kinds of rural development extension efforts (USDA, 1980). Also beyond the range of this essay are evaluations of other kinds of rural development programs, such as capital funding programs to provide water and sewerage systems, roads, etc.
Exploring New Physics with O(keV) Electron Recoils in Direct Detection Experiments

description: Motivated by the recent XENON1T results, we explore various new physics models that can be discovered through searches for electron recoils in O(keV)-threshold direct-detection experiments. First, we consider the absorption of light bosons, either as dark matter relics or being produced directly in the Sun. In the latter case, we find that keV mass bosons produced in the Sun provide an adequate fit to the data but are excluded by stellar cooling constraints. We address this tension by introducing a novel Chameleon-like axion model, which can explain the excess while evading the stellar bounds. We find that absorption of bosonic dark matter provides a viable explanation for the excess only if the dark matter is a dark photon or an axion. In the latter case, photophobic axion couplings are necessary to avoid X-ray constraints. Second, we analyze models of dark matter-electron scattering to determine which models might explain the excess. Standard scattering of dark matter with electrons is generically in conflict with data from lower-threshold experiments. Momentum-dependent interactions with a heavy mediator can fit the data with dark matter mass heavier than a GeV but are generically in tension with collider constraints. Next, we consider dark matter consisting of two (or more) states that have a small mass splitting. The exothermic (down)scattering of the heavier state to the lighter state can fit the data for keV mass splittings. Finally, we consider a subcomponent of dark matter that is accelerated by scattering off cosmic rays, finding that dark matter interacting though an O(100 keV)-mass mediator can fit the data. The cross sections required in this scenario are, however, typically challenged by complementary probes of the light mediator. Throughout our study, we implement an unbinned Monte Carlo analysis and use an improved energy reconstruction of the XENON1T events.

description: The growth in agricultural productivity and significance of science and technology in contributing to this growth has been well documented by Bredahl, Cline, Evenson (1967), Griliches (1964), and Peterson. The results of these studies generally indicate that over the past several decades, investment in agricultural research has paid off with relatively high rates of return. Most of this previous work, however, has been directed at estimating returns to aggregate agricultural research in an ex post sense at the national level and does not address the question of potential future returns to research at a state or regional level (Norton). Thus, a particular need exists to develop a methodology for evaluating the potential returns to specific types of agricultural research at a subnational level. The allocation of agricultural research funds in the United States is determined in large part by political decisionmakers and research administrators at the state level. Although aggregated, national-level, ex post estimates of returns to research are useful to state-level research administrators as indicators of research potential and as a means of justifying funding requests, they are not directly applicable to the larger issues involved. A state-level assessment of the effects of agricultural research should be as situation specific as possible: considering at least the geographic distribution of benefits and the division of benefits between consumers and producers. Essentially, research administrators need to know which types of agricultural research can be expected to have the highest payoffs and to whom the gains will accrue. Answers to questions regarding the magnitude and distribution of agricultural research benefits depend on five primary factors: (1) the impact which a research finding has on production possibilities, (2) the rate and extent of adoption, (3) supply elasticities of the commodities affected, (4) price elasticities of demand for the commodities affected, and (5) agricultural policy. An analysis of potential returns to agricultural research at the state level must consider each of these factors. The purpose of this paper is to present a general conceptual framework for such analyses and also to describe how this framework is being applied in a study of potential returns to research in Nebraska.

description: A class of phenomenological relativistic models of hadronic systems motivated by QCD that have dual representations as models of mesons and nucleons or quarks and gluons is investigated. These models are designed to provided qualitative insight into the role of sea quarks in hadronic structure and reactions. The model assumption is that the Hamiltonian can be divided into two parts; one that involves degrees of freedom in the same connected local and global color singlet and the remaining interactions that allow the connected local and global color singlets to interact. The first class of interactions results in infinite towers of bare "particles" with hadronic quantum numbers. All but a finite number of these remain stable when the second class of interactions is included. The model interactions are expressed in terms of sub-hadronic degrees of freedom, which determine the bare hadronic spectrum and the interactions involving the bare hadrons in terms of a small number of sub-hadronic model parameters. As a first test, this paper considers the simplest case of mesons that interact via a string-breaking interaction. One virtue of this model is that all of the bare meson masses and eigenfunctions can be computed analytically. In addition, the string breaking interaction leads to production vertices that can also be computed analytically. The relativistic wave functions have a light-front kinematic symmetry. The goal is to find a simple relativistic quantum mechanical model based on sub-hadronic degrees of freedom that can provide an efficient, qualitatively consistent description of hadronic masses, lifetimes, cross sections, sea quark effects, and electromagnetic properties. The simplicity of the model makes it a potentially useful tool to study the impact of sea quarks on hadronic structure and reactions.

description: We present an analysis of Chandra observations of the central regions of the cooling flow cluster Abell 2029. We find a number of X-ray filaments in the central 40 kpc, some of which appear to be associated with the currently active central radio galaxy. The outer southern lobe of the steep-spectrum radio source appears to be surrounded by a region of cool gas and is at least partially surrounded by a bright X-ray rim similar to that seen around radio sources in the cores of other cooling flow clusters. Spectroscopic fits show that the overall cluster emission is best fitted by either a two temperature gas (kT_high=7.47 keV, kT_low=0.11 keV), or a cooling flow model with gas cooling over the same temperature range. This large range of temperatures (over a factor of 50) is relatively unique to Abell 2029 and may suggest that this system is a very young cooling flow where the gas has only recently started cooling to low temperatures. The cooling flow model gives a mass deposition rate of Mdot=56 +16/-21 Msun/yr. In general, the cluster emission is elongated along a position angle of 22 degrees with an ellipticity of 0.26. The distribution of the X-ray emission in the central region of the cluster is asymmetric, however, with excess emission to the north-east and south-east compared to the south-west and north-west, respectively. Fitting and subtracting a smooth elliptical model from the X-ray data reveals a dipolar spiral excess extending in a clockwise direction from the cluster core to radii of ~150 kpc. We estimate a total mass of M_spiral ~6 x 10^12 Msun in the spiral excess. The most likely origins of the excess are either stripping of gas from a galaxy group or bare dark matter potential which has fallen into the cluster, or sloshing motions in the cluster core induced by a past merger.

Ex Ante Evaluation of the Separate Effects of Research and Extension

Year: 1981
Subjects: Research and Development/Tech Change/Emerging Technologies

description: Much research work has been conducted in recent years to evaluate the effects of research and extension.2/ Some of these efforts were conducted at the national aggregate level, while others were conducted at the regional or community levels. The methodologies used in those studies varied, but most of the studies were based on regression analysis of ex post data. There are several difficulties associated with the above ex post analyses. First, the time lags from the time of research resource commitment to production of extendable technology (invention), i.e., the leadtime, ranges from a few years to decades. It is difficult to collect time series data to accommodate a long leadtime. Besides, the average lead time is not known unless one studies specific research projects. Thus, most, if not all, researchers ignore the leadtime. They just assume that research output will come about as soon as the research resources are committed, even though most researchers recognize and account for adoption lag. Secondly, research and extension enter into the process of technological innovation at different points in time. Although feedbacks from extension often result in changes in the direction or additional research to be conducted, extension plays little role in the development of a new technology. When the research is completed and a new technology is produced, extension comes into play. Thus, extension follows research in that process. Many researchers recognize this lag, but unless dealing with a specific technology, the lag length is usually unknown. Thirdly, in time series data, research and extension expenditures are highly collinear. One reason for the existence of this collinearity is that the budgets are allocated or authorized for both functions regarding the same issue at the same time. Attempts to estimate the separate effects of research and extension using the regression analysis often fail. Fourthly, all ex post analyses were based on data since World War I when fossil fuel was cheap and abundant. Since the likelihood of having cheap and abundant fossil fuel in the future is very slim, the estimated relationships may not be relevant in predicting or planning for the future. This study proposes an alternative approach to overcome the above difficulties. The purpose of this study is to describe proposed methodology and procedures to estimate the separate rates of return to research and extension in U.S. agriculture using an ex ante analysis.

description: © 2017 International Press. We study the long time behavior of solutions to a nonlinear partial differential equation arising in the mean-field description of trapped rotating Bose-Einstein condensates. The equation can be seen as a hybrid between the well-known nonlinear Schrödinger/Gross-Pitaevskii equation and the Ginzburg-Landau equation. We prove existence and uniqueness of global in-time solutions in the physical energy space and establish the existence of a global attractor within the associated dynamics. We also obtain basic structural properties of the attractor and an estimate on its Hausdorff and fractal dimensions. As a by-product, we establish heat-kernel estimates on the linear part of the equation.

description: It was previously shown that control-flow refinement can be achieved by a program specializer incorporating property-based abstraction, to improve termination and complexity analysis tools. We now show that this purpose-built specializer can be reconstructed in a more modular way, and that the previous results can be achieved using an off-the-shelf partial evaluation tool, applied to an abstract interpreter. The key feature of the abstract interpreter is the abstract domain, which is the product of the property-based abstract domain with the concrete domain. This language-independent framework provides a practical approach to implementing a variety of powerful specializers, and contributes to a stream of research on using interpreters and specialization to achieve program transformations.

description: Previous efforts to automate the detection of social and political events in text have primarily focused on identifying events described within single sentences or documents. Within a corpus of documents, these automated systems are unable to link event references -- recognize singular events across multiple sentences or documents. A separate literature in computational linguistics on event coreference resolution attempts to link known events to one another within (and across) documents. I provide a data set for evaluating methods to identify certain political events in text and to link related texts to one another based on shared events. The data set, Headlines of War, is built on the Militarized Interstate Disputes data set and offers headlines classified by dispute status and headline pairs labeled with coreference indicators. Additionally, I introduce a model capable of accomplishing both tasks. The multi-task convolutional neural network is shown to be capable of recognizing events and event coreferences given the headlines' texts and publication dates.

description: We present a new method for component separation aimed to extract Sunyaev-Zeldovich (SZ) galaxy clusters from multifrequency maps of Cosmic Microwave Background (CMB) experiments. This method is designed to recover non-Gaussian, spatially localized and sparse signals. We first characterize the cluster non-Gaussianity by studying it on simulated SZ maps. We the apply our estimator on simulated observations of the Planck and Atacama Cosmology Telescope (ACT) experiments. The method presented here outperforms multi-frequency Wiener filtering both in the reconstructed average intensity for given input and in the associated error. In the absence of point source contamination, this technique reconstructs the ACT (Planck) bright (big) clusters central y parameter with an intensity which is about 84 (43) per cent of the original input value. The associated error in the reconstruction is about 12 and 27 per cent for the 50 (12) ACT (Planck) clusters considered. For ACT, the error is dominated by beam smearing. In the Planck case the error in the reconstruction is largely determined by the noise level: a noise reduction by a factor 7 would imply almost perfect reconstruction and 10 per cent error for a large sample of clusters. We conclude that the selection function of Planck clusters will strongly depend on the noise properties in different sky regions, as well as from the specific cluster extraction method assumed.

description: Initial Negotiating Rights is a useful tool to find a compromise in the WTO bilateral negotiations, particularly in the accession stage. This policy brief sheds light on the provisions of INRs in the WTO. It also elaborates a number of case studies, and draws some recommendations. Particularly, the paper focuses on the INRs and small and medium –sized countries, and the reasons which pushed these countries to confer INRs.

description: Optical diagnostic diagrams are powerful tools to separate different ionizing sources in galaxies. However, the model-constraining power of the most widely-used diagrams is very limited and challenging to visualize. In addition, there have always been classification inconsistencies between diagrams based on different line ratios, and ambiguities between regions purely ionized by active galactic nuclei (AGNs) and composite regions. We present a simple reprojection of the 3D line ratio space composed of [N II]$λ6583$/H$α$, [S II]$λλ$6716, 6731/H$α$, and [O III]$λ$ 5007/H$β$, which reveals its model-constraining power and removes the ambiguity for the true composite objects. It highlights the discrepancy between many theoretical models and the data loci. With this reprojection, we can put strong constraints on the photoionization models and the secondary nitrogen abundance prescription. We find that a single nitrogen prescription cannot fit both the star-forming locus and AGN locus simultaneously, with the latter requiring higher N/O ratios. The true composite regions stand separately from both models. We can compute the fractional AGN contributions for the composite regions, and define demarcations with specific upper limits on contamination from AGN or star formation. When the discrepancy about nitrogen prescriptions gets resolved in the future, it would also be possible to make robust metallicity measurements for composite regions and AGNs.

What facilitates and hinders recovery from traumatic brain injury : a critical incident study
Creators: name: Hayoun, Revital
Publisher: name: University of British Columbia
Year: 2009

description: Recovery from traumatic brain injury (TBI) involves more than just the physical dimension or just the time period in which a person is involved in a rehabilitation program. In fact it is during the post rehabilitation phase, with its concomitant changes in routine, that behavioural difficulties emerge and recovery becomes an ongoing process of adjustment. The purpose of this thesis was to discover what facilitates and what hinders recovery from traumatic brain injury (TBI) for late adolescents upon discharge from rehabilitation. The Critical Incident Technique (Flanagan, 1954) was employed to elicit the different resources that assist/encourage and hinder/discourage recovery from TBI as reported by the individual. Six late adolescents with mild-moderate TBI were interviewed one to eight years after their injury. A total of 165 critical incidents were extracted and organized into 16 categories describing what late adolescents with TBI experienced to enhance their recovery. Following extensive validation procedures, the scheme of categories was found meaningful and useful for both counselling and research. In addition, the internal and external types of motivation involved within the 16 categories were discussed. It is hoped that the findings of this study will provide the groundwork for future research in developing assessment tools and treatment programs.

description: We report the discovery of a new mechanism of spontaneous generation of a magnetic flux in a superconductor cooled through $T_c$. The sign of the spontaneous flux changes randomly from one cooldown to the next, and follows a Gaussian distribution. The width of the distribution increases with the size of the temperature gradient in the sample. Our observations appear inconsistent with the well known mechanisms of flux generation. The dependence on the temperature gradient suggests that the flux may be generated through an instability of the thermoelectric superconducting-normal quasiparticle counterflow.

description: Samarium modified SrBi4-xSmxTi4O15 (x = 0, 0.13, 0.43 and 0.78) ferroelectric ceramics of Aurivillius family were prepared by conventional solid state reaction method. X-ray diffraction studies confirm the formation of a single-phase. Microstructural images show randomly oriented palate-like structure. Broad dielectric peaks were found to obey the modified Curie-Weiss law. The overall inherent ferroelectric nature was explained on the basis of the Avrami model. Furthermore, with increasing the Sm3+ content, the grain morphology and diffusive parameters have shown a comprehending impact on the ferroelectric (hysteresis) behavior.
Discovery of high-amplitude X-ray variability in the Seyfert-LINER transition galaxy NGC7589

description: We present the first result of a programme to search for large flux variations in the X-ray sources of the XMM Serendipitous Survey compared to previous ROSAT observations. An increase in X-ray flux by a factor >10 was discovered from the nucleus of the galaxy NGC7589 on a timescale of less than 5 years. The 0.4-10keV XMM spectrum can be approximated by a power-law with photon index of 1.7-1.8, though it seems to flatten above 5keV, suggesting a possible complex model, such as partial covering or disc reflection. A classification based on an analysis of its optical spectrum places NGC7589 in the Seyfert region, but close to the Seyfert-LINER border-line on the AGN diagnostic diagrams. We classify NGC7589 as either Seyfert1.9 or LINERI, in the light of the detection of a broad H_alpha line, which makes NGC7589 an AGN in the low-luminosity regime. We interpret the observed variability in terms of either changes in covering factor of absorbing gas in the AGN, or variability in the intrinsic X-ray luminosity. Should the latter be the case, the inferred Eddington accretion rate increased from the radiatively inefficient accretion dominated regime to a value close to the putative critical value, at which a transition of the accretion mode is supposed to take place. This possibility presents a new prospect of studying accretion physics in the central black holes of external galaxies by direct observing changes of `spectral state', as is common in stellar black hole binary systems.

description: We present: 1) a kinematic and morphological study of the giant Lya nebula associated with the radio galaxy MRC2104-242 (z = 2.49) based on integral field spectroscopic VIMOS data from VLT; 2) a photometric study of the host (proto?) galaxy based on Spitzer Space Telescope data. The galaxy appears to be embedded in a giant (>120 kpc) gas reservoir that surrounds it completely. The kinematic properties of the nebula suggest that it is a rotating structure, which would imply a lower limit to the dynamical mass of ~3 x 1e11 Msun. An alternate scenario is that the gas is infalling. Such a process would be able to initiate and sustain significant central starburst activity, although it is likely to contribute with less than 10% of the total stellar mass of the galaxy. The near- to mid-IR spectral energy distribution of the radio galaxy suggests the existence of a reddened, E(B-V)=0.4(+/-)0 .1$, evolved stellar population of age >~ 1.8 Gyr and mass 5(+/-)2 x 1e11 Msun. The implied formation redshift is z_f >~ 6. This stellar mass is similar to the stellar masses found for massive early-type galaxies at z~2 in deep, near-infrared surveys.

The issue of time in generally covariant theories and the Komar-Bergmann approach to observables in general relativity

description: Diffeomorphism-induced symmetry transformations and time evolution are distinct operations in generally covariant theories formulated in phase space. Time is not frozen. Diffeomorphism invariants are consequently not necessarily constants of the motion. Time-dependent invariants arise through the choice of an intrinsic time, or equivalently through the imposition of time-dependent gauge fixation conditions. One example of such a time-dependent gauge fixing is the Komar-Bergmann use of Weyl curvature scalars in general relativity. An analogous gauge fixing is also imposed for the relativistic free particle and the resulting complete set time-dependent invariants for this exactly solvable model are displayed. In contrast with the free particle case, we show that gauge invariants that are simultaneously constants of motion cannot exist in general relativity. They vary with intrinsic time.
