Do job-seekers benefit from contacts? : a direct test
… the source of this association by proposing a direct test for whether or not a job-seeker benefits from using her social networks. This direct test holds an important advantage over an indirect test proposed by Mouw (2003). By using a within-individual fixed-effects methodology, the direct test …

Does using social networks lead to better job opportunities? : a direct test
Research on the effect of social networks on job search outcomes has provided mixed results. Some studies found that the use of social contacts has positive effects on wages and on the other indicators of job quality while some others found negative effects. Previous studies, however, suffered from …

On the complexity of energy landscapes: algorithms and a direct test of the Edwards conjecture
… jammed soft-sphere packings and produce a direct test of the Edwards conjecture for the equivalent two dimensional systems. We find that Edwards’ hypothesis of equiprobability of all jammed states holds only at the (un)jamming density, that is precisely the point of practical significance …

Does having women in positions of power reduce gender inequality in organizations? : a direct test
… for these inconsistent results. First, because direct data on the impact of male versus female managers on the career outcomes of their employees is difficult to obtain, prior studies have measured the impact of women in positions of power on gender inequality using industry or …

A Validation Study of a Writing Skills Test for Police Recruit Applicants
This study evaluated the effectiveness of a direct test of higher-order and lower-order writing abilities needed for police report writing. This test was specifically designed to address report writing deficiencies experienced by police in the training academy. Descriptive statistics were examined, …

An empirical evaluation of the capital asset pricing model in South Africa
… to 1980 is evaluated. The study is the first direct test of the CAPM in South Africa. The methodology employed is a cross-sectional regression technique which has been used successfully in testing overseas security markets. An extension to the usual methodology is made by comparing the results …

Why wait? Psycholinguistic investigations of the roles of learning condition and gender stability in L2 gender-based anticipation
… this dissertation provides the first direct test of the LGLH. Results do not find evidence for the claim that learning context affects the stability of gender assignments nor the ability to use gender as an anticipatory cue. The data do, however, support the hypothesis that gender …

THE INTERACTION OF INTERNAL AND EXTERNAL FOCUS IN SOCIAL ANXIETY: CLARIFYING COGNITIVE BEHAVIORAL MODELS
… social situations. This study provides a direct test of this discrepancy, predicting that persons who scored high and low on a measure of communication anxiety would exhibit differences on measures of self-focused attention and environment-focused attention, in support of the model of …

Molecular mechanisms of radial axonal growth : insights from analysis of neurofilament gene-targeted mice
… the magnitude that axons grow radially. As a direct test, I increased the length of NF-M in mice through gene replacement. Expanding NF-M length resulted in mice with larger diameter axons yet myelin thickness did not increase around the axons, suggesting that myelin lacked plasticity to …

Three Essays on the Housing Market
… relocating accordingly. We provide the first direct test of the role played by housing discrimination proposed by Kain's Spatial Mismatch Hypothesis. Combining a large-scale fair housing audit study and granular employment data, we detect suggestive evidence on housing agents' steering …

Privileging Tacit Knowledge within a Software Engineering Curriculum: A Living Educational Theory of Practice
… standards of judgement that I developed to direct, test, and evaluate actions I took to improve my pedagogical practice. I describe how I experienced conflict between my existing practice and ontological values that led me to see myself as a ‘living contradiction’ (Whitehead, 1989, p.41) and …

Glia-neuron signaling
… culture is the simplest experimental method of testing the hypothesis that glia can signal to neurons, a second technique allowed a more direct test of this hypothesis. Direct photo-stimulation of glia was used to increase glial calcium levels. A portion of glia was exposed to focal application …

Ignition delay study of next generation alternative jet fuels in a rapid compression machine
… blend of decane and trimethylbenzene (C-5) are tested through the study. A rapid compression machine at the University of Illinois at Urbana-Champaign is used for testing, with the direct test chamber charge preparation method. DTC configuration has advantages in avoiding thermal decomposition …

Emergent behaviors in complex microbial ecosystems
… this knowledge gap by conducting the first direct test of a theory proposing that simple community-level features govern emergent behaviors. By utilizing bacterial microcosms, we demonstrate that as the number of species or the strength of interactions increases, microbial ecosystems …

An Experimental Study of Teachers' Verbal and Nonverbal Immediacy, Student Motivation, and Cognitive Learning in Video Instruction
This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to …

A concurrent validation study of the United States Employment Service's validity generalization job family four scores
… Service has implemented a recently developed testing program. The Validity Generalization (VG) Testing Program, adopted its name from the meta-analytic technique which cumulates the findings of test validation studies. For this testing program, predictors were developed for five job families …

Investigating Causal Relationships between Global Change and Insect Interaction Networks: Insights into Dietary Specialization, Interaction Diversity, and Disturbances
… of specialists towards the equator. As a more direct test of future global change on arthropod networks, I examined a temporal gradient in arthropod networks before and after fire disturbance in the eastern Sierra Nevada mountains. I found that a prescribed fire created classic early …

Migration of olfactory ensheathing cells grafted into adult rat spinal cord
… of the injured CNS. However, there has been no direct test of their migratory ability in vivo. The aims of this study were to determine whether: 1) OECs can be induced to migrate towards an ethidium bromide (EtBr)-induced focal (~1 mm long) demyelination of the spinal cord white matter; 2) OECs …
