Load bearing capacity, fracture mode, and wear performance of digitally veneered full-ceramic single crowns.

OBJECTIVES Computer-aided technologies can help to minimize clinical complications of zirconia-based restorations such as veneering porcelain fractures. The aim of this study was to evaluate different veneering approaches for zirconia single crowns regarding contact wear, fracture strength, and failure mode. METHODS Six different types of computer-aided design (CAD) crowns were manufactured and conventionally cemented on 10 metal dies each: three groups with a zirconia framework and a CAD/CAM-fabricated veneering cap ("digital veneering system": DVS, CAD-on, Infix CAD), zirconia-based crowns with pressed veneering caps (Infix Press), zirconia framework containing the dentin layer with only the incisal enamel material added (dentin-core), and conventional substructure with powder buildup veneering porcelain (layering technique). All specimens were submitted to artificial aging (120,000 mechanical cycles, 50 N load, 0.7-mm sliding movement, 320 thermocycles). After contact wear was measured with a laser scanning system, fracture resistance and failure mode were examined using a universal testing machine and a scanning electron microscope. Statistical analysis was performed at a significance level of 5%. RESULTS No statistical difference was revealed regarding the contact wear of the restorations (P = 0.171; ANOVA). No significant difference was found regarding the fracture resistance of the crowns (P = 0.112; ANOVA). Failure analysis revealed three different failure patterns: cohesive veneering fracture, adhesive delamination, and total fracture, with a characteristic distribution between the groups. SIGNIFICANCE All tested specimens survived artificial aging and exhibited clinically acceptable wear resistance and fracture resistance. Digital veneering techniques offer a promising, time- and cost-effective manufacturing process for all-ceramic restorations and may usefully complement the digital workflow.
Deriving conditional and unconditional marginal effects in log earnings equations estimated by Heckman's procedure

Although the Heckman approach has often been used in empirical analysis, the marginal effects, necessary to interpret the effect of the regressors on the dependent variable, appeared to be overlooked. Using the Heckman approach, general expressions are derived for calculating the conditional and unconditional marginal effects. Based on a sample of Brazilian women, the conditional and unconditional return to education are calculated for the logarithm of earnings equation estimated by Heckman's procedure, comparing them to the marginal effect of education obtained without correcting for selectivity bias. The same analysis is carried out for a discrete variable ‘black’.
Determinants of interstate differentials in the cost of housing, 2006

This empirical study investigates determinants of interstate differentials in the cost of housing for the year 2006. While the literature on geographic cost-of-living differentials is well developed, the literature on geographic cost-of-housing (as opposed to housing-price) differentials is much less so. Housing costs consist of the price of housing per se for owners or rental payments per se for renters plus utility costs. The significance of this research is elevated by the fact that the cost of housing is the main driver of cost-of-living differences between states. The OLS results imply that the cost of housing in a state is positively a function of the state's median family income, its heating degree days, and its mean January temperature, and negatively a function of toxic waste releases in the state, the state's property crime rate, and the presence of right-to-work laws in the state.
Bankruptcy Prediction Revisited: Non-Traditional Ratios and Lasso Selection

This study pursues two issues in the context of reduced-type bankruptcy prediction. First, we investigate the marginal usefulness of some non-traditional ratios and indicators. We find that the performance of traditional ratios can be considerably improved by their squared terms and technical ratios built from itemized accounts. Also, missing values for many items are found informative.Second, the non-traditional ratios dramatically increase the number of candidate variables, which makes the variable selection particularly important. We show that the innovative lasso regularization performs for these purposes significantly better than the traditional stepwise method.All in all, the non-traditional information increases the cross-validated accuracy ratio by 1.9%. When applying the lasso method instead of stepwise, this advantage increases to 2.3%, along with a considerable reduction in computer processing time but, admittedly, at the cost of a significantly higher number of variables chosen. Lasso also has some methodological advantages, being e.g. able to efficiently select non-traditional ratios which complement (rather than replace) traditional ones.
Factors that Impact Implementing a System Development Methodology

Presents the findings of empirical research from 61 companies, mostly from the USA, to identify the factors that may impact implementation of a system development methodology (SDM). The study uses a survey instrument to identify the SDM implementation factors. The survey focused on the perspective of the primary constituents: functional managers, information systems managers, system personnel and external consultants. The study uses an exploratory factor analysis that identifies five factors important to implementing an SDM: organizational SDM transition, functional management involvement/support, SDM transition, the use of models and external support. The research findings have important implications for further research and the practice of system development. For researchers, it points to important measures in the implementation and use of SDMs that may be further verified and extended in subsequent research. For practitioners, it provides a general guide to the important aspects to consider in the implementation and use of an SDM.
Development and Psychometric Analysis of the Brief DSM–5 Alcohol Use Disorder Diagnostic Assessment: Towards Effective Diagnosis in College Students

The Diagnostic and Statistical Manual of Mental Disorders (5th edition) Alcohol Use Disorder (DSM–5 AUD) criteria have been modified to reflect a single, continuous disorder. It is critical that we develop brief assessment measures that can accurately assess for DSM–5 AUD criteria in college students to assist in screening, referral, and brief intervention services implemented on college campuses. The present study sought to develop and assess for the psychometric properties of a brief 13-item measure designed to capture the full spectrum of the DSM–5 AUD criteria in a sample of college students. Participants were past-year drinkers (N = 923) between the ages of 18 to 30 enrolled at 3 universities. Respondents completed a 30-min anonymous battery of questionnaires online. The Brief DSM–5 AUD Assessment consisted of 13 items designed to reflect the DSM–5 AUD criteria. Results indicated a high degree of internal consistency reliability with high item-to-scale correlations. Confirmatory factor analyses indicated that a dominant single factor emerged with good model fit. The Item Response Theory (IRT) analyses indicated that the difficulty parameters for each criterion were intermixed along the upper portion of the underlying AUD severity continuum, and the discrimination parameters were all high. Additional analysis indicated that those with a DSM–5 AUD had greater levels of alcohol and other drug use and problem severity in comparison to those without a DSM–5 AUD. Study findings provide empirical support for the reliability and validity of the Brief 13-item DSM–5 Assessment. It should be routinely included into research and clinical practice efforts.
Racial differences in contraceptive choice: Complexity and implications

Previous research has failed to generate consensus about why black fertility has persistently exceeded that of whites in the United States. In an effort to shed light on this question, this article examines black/white differences in sociodemographic factors affecting contraceptive choice. Using data from the 1976 and 1982 National Surveys of Family Growth, we find a complex pattern of black/white differences. Not only does contraceptive choice vary by race, but the effects of such variables as age, marital status, and education also differ between blacks and whites. For example, compared with whites, black married women avoid coital methods, and compared with blacks, white women shift contraceptive behavior more as they change marital status. The complex nature of the racial differences in contraceptive choice are interpreted as reflecting differences in marriage patterns and trends.
Functional Characterization of Deformation Fields

In this article, we present a novel representation for deformation fields of 3D shapes, by considering the induced changes in the underlying metric. In particular, our approach allows one to represent a deformation field in a coordinate-free way as a linear operator acting on real-valued functions defined on the shape. Such a representation provides both a way to relate deformation fields to other classical functional operators and enables analysis and processing of deformation fields using standard linear-algebraic tools. This opens the door to a wide variety of applications such as explicitly adding extrinsic information into the computation of functional maps, intrinsic shape symmetrization, joint deformation design through precise control of metric distortion, and coordinate-free deformation transfer without requiring pointwise correspondences. Our method is applicable to both surface and volumetric shape representations and we guarantee the equivalence between the operator-based and standard deformation field representation under mild genericity conditions in the discrete setting. We demonstrate the utility of our approach by comparing it with existing techniques and show how our representation provides a powerful toolbox for a wide variety of challenging problems.
Testing How Management Matters in an Era of Government by Performance Management

Public administration finds itself in an era of government by performance management, which is reflected in the widespread assumption that management is a key determinant of performance, and that it is reasonable to expect managers to measurably improve organizational effectiveness. This article joins a growing literature in seeking to conceptualize and empirically test how external environmental influences and internal management factors combine to create performance, relying on data from the 2002–2003 National Administrative Studies Project (NASP-II) survey of state government health and human services officials. We categorize managerial efforts to facilitate organizational performance as determined either through their interactions with the organizational environment, or through employing workable levers to change internal organizational culture, structure, and technology. Among the external environmental variables we find that the support of elected officials and the influence of the public and media have a positive impact on effectiveness. Among internal management choices, the ability to create a developmental organizational culture, establish a focus on results through goal clarity, and decentralize decision-making authority are all positively associated with organizational effectiveness. AN ERA OF GOVERNMENT BY PERFORMANCE MANAGEMENT Frederick Mosher’s Democracy and the Public Service (1982) characterizes the history of public administration in the United States as falling into different eras. He portrays the twentieth century as dominated by two phases: government by the efficient (1906–1937), This is a revised version of a paper originally presented at the National Public Management Research Conference, October 9–11, 2003, at Georgetown University.

ON MEASURING YIELD POTENTIAL OF THE HIGH YIELDING VARIETIES TECHNOLOGY AT FARM LEVEL

Among rice scientists in developing countries there is a general belief that on-farm rice yields are far below their potential level. There is considerable controversy about the appropriate methodology to define and measure the potential yield at the farm level within the farmers' environment. Most of the methodologies are based on agronomic criteria and neglect the farmers' socio-economic environment. The aim of this paper is to define the potential yield at the farm level incorporating the economic environment farmers face. This potential yield so defined is feasible in that it could be realised by all farmers with existing technology, provided that they have access to necessary inputs. Measuring potential yield in this way is also desirable from a welfare viewpoint.
Dyadic effects of gender minority stressors in substance use behaviors among transgender women and their non-transgender male partners.

BACKGROUND Despite evidence that interpersonal processes shape health behaviors, research concerning the dyadic effects of gender minority stressors on substance use behaviors of transgender people is scarce. The objective of this study was to use dyadic analysis to examine whether transgender discrimination was associated with substance use among transgender women and their male partners. METHODS Transgender women and their male partners (N=191 couples; N=382 individuals) completed questionnaires. Participants' mean age was 37.1; 79.1% were racial/ethnic minority; 61.3% earned <$500 per-month. The mean relationship duration was 37.9 months. Actor-Partner Interdependence Models were used to examine the associations between transgender-related discrimination and past 30-day non-marijuana illicit drug use adjusting for age, relationship length, financial hardship, and depressive distress among partners in these dyads. RESULTS Illicit drug use was reported by 31.4% of transgender women and 25.1% of their male partners. Perceived transgender discrimination was independently associated with increased odds of illicit drug use for transgender women (actor effect) but not for their male partners. Financial hardship statistically predicted drug use for both partners (actor effects). There were no partner effects for financial hardship on drug use. Overall, 34.5% of dyads had discrepant substance use. Discrimination scores of male partners differentiated dyads who reported discrepant substance use. DISCUSSION Gender minority stressors are critical to understanding substance use among transgender women and their male partners. Integrating socioeconomic status into gender minority stress frameworks is essential. Results have implications for substance use prevention and treatment, including the need to incorporate gender minority stressors into interventions.
Strategic Political Postures and Political Market Orientation: Toward an Integrated Concept of Political Marketing Strategy

Recently, the areas of strategic political marketing and political market orientation have been the subject of several conceptual articles that have provided the theoretical foundations for further empirical work. However, despite the close conceptual relatedness of the proposed concepts, they have yet to be integrated to provide a more nuanced framework that both researchers and political marketing practitioners can utilize in the development of strategies and offerings with which to achieve their organizational goals. The aim of this conceptual article is to address this deficit by developing an integrated concept of political marketing strategy using two complementary frameworks, namely strategic political postures and political market orientation (PMO). The authors introduce the two main concepts and derive for each of the strategic posture-specific PMO profiles as well as interconstruct relationships.
Thin Profile Wideband Printed Monopole Antenna for Slim Mobile Handsets Applications

In this paper, a compact wideband planar monopole antenna suitable for slim mobile handsets applications is presented. The proposed antenna operates over LTE700/GSM800/900 (0.742 GHz-1.36 GHz), GPS L1/GSM1800/1900/UMTS/IMT2100/Wi-Fi/LTE2300/2500 (1.475 GHz- 2.7 GHz), and WiMAX (3.4 GHz-3.72 GHz) based on reflection coefficient better than − 6d B. It consists of coupling strip, shorted radiating strip, and parasitic meandered lines. The wider impedance bandwidth is achieved by placing the meandered line as parasitic element on the back side of the coupling and shorted radiating elements. With this configuration, the antenna gives extremely wide impedance bandwidth which covers all the required frequency bands of the smart mobile phones. To investigate the proposed antenna, S-parameters, surface current distributions, and radiation performances are studied. To check the robustness of the proposed antenna, investigation is also carried out in the vicinity of the mobile environment. Further, specific absorption rate (SAR) is calculated on the human head and found to be below 0.535 W/kg. The simulated and measured results are found in close agreement.
Dispersal differences predict population genetic structure in Mormon crickets

Research investigating the geographical context of speciation has primarily focused on abiotic factors such as the role of Pleistocene glacial cycles, or geotectonic events. Few study systems allow a direct comparison of how biological differences, such as dispersal behaviour, affect population genetic structure of organisms that were subdivided during the Pleistocene. Mormon crickets exist in solitary and gregarious ‘phases’, which broadly correspond with an east–west mtDNA division across the Rocky Mountains. Gregarious individuals form bands that can move up to 2 km daily. This study assessed whether population genetic structure results mainly from deep Pleistocene vicariance or if we can also detect more recent genetic patterns due to phase and dispersal differences superimposed on the older, deeper divisions. We found that separation in refugia was a more important influence on genetic divergence than phase, with the Rockies acting as a barrier that separated Mormon cricket populations into eastern and western refugia during Pleistocene glacial cycles. However, patterns of isolation by distance differ between eastern and western clades for both mitochondrial and nuclear DNA, with greater divergence within the eastern, solitary clade. An mtDNA haplotype mismatch distribution is compatible with historical population expansion in the western clade but not in the eastern clade. A persistent (and possibly sex‐biased) difference in dispersal ability has most likely influenced the greater population genetic structure seen in the eastern clade, emphasizing the importance of the interaction of Quaternary climate fluctuations and geography with biotic factors in producing the patterns of genetic subdivision observed today.
Induction of leafy galls in Acacia mearnsii De Wild seedlings infected by Rhodococcus fascians

Plantlets of blackwattle (Acacia mearnsii De Wild) were inoculated with the bacterium Rhodococcus fascians and cultured in vitro. Leafy galls appeared at the cotyledonary nodes in 75% of the infected plants. The galls were separated from the plants and cultured on a medium containing three-quarters-strength MS salts (Murashige and Skoog, 1962), MS vitamins, 2% sucrose and an antibiotic (cephalothin), supplemented with or without 0.2% activated charcoal. Histological studies conducted from the sixth to the twenty-second day after plant infection revealed the presence of newly formed meristematic centers, first in the axillary region, then on the petioles and lamina of the leaflets around the apical meristem. Approximately 37% of the galls developed one shoot with both concentrations of cephalothin.
What Determines Demographic Similarity Between Incumbent CEOs and Their Successors? A CEO Informal Power Perspective

As CEOs reach the end of their tenure, they attempt to influence the decision about who will replace them in order to safeguard what they have put in place. This prompts them to favor candidates who share similar demographic profiles whom they believe will carry on where they leave off. We suggest that as CEOs are not usually given the authority to name a successor, they make use of informal power to exert their influence. We test our hypotheses on a sample of 137 CEO successions in 67 German diversified companies between 1985 and 2007 and find strong support for our theoretical reasoning that the more informal power incumbent CEOs have, the greater the demographic similarity between them and their successors.

Adaptive Visual Servoing of Unmanned Aerial Vehicles in GPS-Denied Environments

This paper presents an adaptive output feedback-based visual servoing law for a quadrotor unmanned aerial vehicle equipped with a single downward facing camera. The objective is to regulate the relative position and yaw of the vehicle to a planar target consisting of multiple points using a minimal sensor set, i.e., an inertial measurement unit and a vision sensor. A set of first order image moment features, defined in the image plane of a virtual camera with zero roll and pitch motion, is used for visual servoing. It has been observed in previous work that various system uncertainties, such as aerodynamics constants and attitude estimation bias, result in steady-state errors if not being compensated. By treating those uncertainties as unknown system parameters, an adaptive backstepping controller is developed. As the given visual servoing law is an output feedback controller, the translational velocity measurement from the global position system is not required. The asymptotic stability of the error dynamics is proven. Experimental results are provided to demonstrate the controller performance.
