Vascular endothelial growth factor polymorphisms as effect modifiers of oral squamous cell carcinoma risk: A systematic review and meta-analysis.
2014
Smoking is one of the main risk factors for the development of oral squamous cell carcinoma (OSCC). Smoking may affect single-nucleotide polymorphism (SNP)-dependent vascular endothelial growth factor (VEGF)-induced angiogenic activity. Therefore, we systematically reviewed the published VEGF-SNP genotype data of OSCC patients and healthy individuals and performed a meta-analysis comparing the VEGF-SNP genotypes of smoking and non-smoking patients in association with OSCC incidence. Prospective and retrospective studies on the clinical comparison of OSCC patients with different VEGF-SNP genotypes were reviewed. The meta-analysis re-pooled studies of smoking and non-smoking OSCC patients wit…
Work values and the transition to work life: A longitudinal study
2015
Abstract Research on career development has shown that work values play a key motivational role in job selection and career development. In the context of the current economic crisis, it is of particular relevance to examine the role of work values for employment in the transition from school to work. This longitudinal study examined the role of intrinsic (perceived importance of having a job that is interesting and matches one's own competences), rewards (having a good salary and high chance for promotion), and security (having a stable job) work values on subsequent employment status and person–job fit (how an individual's job matches one's own characteristics such as education and job pr…
Compensating Need Satisfaction across Life Boundaries: A Daily Diary Study
2017
Self-determination theory suggests that satisfaction of an individual's basic psychological needs (for competence, autonomy, and relatedness) is a key for well-being. This has gained empirical support in multiple life domains, but little is known about the way that need satisfaction interacts between work and home. Drawing from ideas of work–home compensation, we expect that the benefits of need satisfaction in the home domain are reduced when needs are satisfied in the work domain. We tested this hypothesis with a daily diary study involving 91 workers. Results showed that individuals particularly benefit from satisfaction of their need for competence in the home domain when it is not sati…
General causality orientations in self-determination theory: Meta-analysis and test of a process model
2020
Causality orientations theory, a key sub-theory of self-determination theory, identifies three distinct causality orientations: autonomy, control, and impersonal orientation. The theory proposes generalized effects of the orientations on motivation and behavior. We meta-analyzed studies ( k = 83) testing relations between causality orientations, forms of motivation from self-determination theory, and behavior. Pooled data were used to test a process model in which autonomous and controlled forms of motivation mediated relations between causality orientations and behavior. Results revealed that autonomy and control orientations were positively correlated with autonomous and controlled forms…
Mandibular ramus flexure and gonial eversion as morphologic indicators of sex.
2002
Summary Recently, two mandibular traits – ramus flexure and gonial eversion – have come under close scrutiny (Loth & Henneberg 1996, 2000). The present study investigates the reliability of these two traits when each is applied as a single and independent indicator of sex, including the question of repeatability. The investigation was designed to give insights into possible confounding factors such as age and remodeling after tooth loss. Two samples, one of forensic (N = 153) and one of archaeological provenance (N = 80), were examined. The forensic sample was evaluated by a single observer while the archaeological sample was independently scored by three different observers. The results do…
Anterior teeth root inclination prediction derived from digital models: A comparative study of plaster study casts and CBCT images
2018
Background To assess the accuracy of digital models generated using commercially available software to predict anterior teeth root inclination characteristics and compare the results to relevant data obtained from CBCT images. Material and Methods Following sample size calculation and after application of inclusion and exclusion criteria, pre-treatment maxillary and mandibular plaster models and the corresponding CBCT scans of 31 patients attending a private orthodontic clinic were selected. The subjects were 10 males and 21 females with age range 12 to 40 years. Plaster models were scanned using the high resolution mode of an Ortho Insight 3D scanner and CBCT scans were taken using a Kodak…
Manipulating the alpha level cannot cure significance testing
2018
We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple in…
Assessing Non-Photosynthetic Cropland Biomass from Spaceborne Hyperspectral Imagery
2021
Non-photosynthetic vegetation (NPV) biomass has been identified as a priority variable for upcoming spaceborne imaging spectroscopy missions, calling for a quantitative estimation of lignocellulosic plant material as opposed to the sole indication of surface coverage. Therefore, we propose a hybrid model for the retrieval of non-photosynthetic cropland biomass. The workflow included coupling the leaf optical model PROSPECT-PRO with the canopy reflectance model 4SAIL, which allowed us to simulate NPV biomass from carbon-based constituents (CBC) and leaf area index (LAI). PROSAIL-PRO provided a training database for a Gaussian process regression (GPR) algorithm, simulating a wide range of non…
A review of DEA models when the internal structure of the decision making units is considered
2005
Classical Data Envelopment Analysis (DEA) models consider each Decision Making Unit (DMU), whose relative efficiency they evaluate, as a "black box", i.e., its internal structure is disregarded. The paper presents a comprehensive framework of the most advanced theoretical findings in DEA when the internal structure of the. DMUs is taken into account, thus giving directions for novel applications of such methodology and introducing it as a powerful toot for complex processes performance evaluation.
Eine einfache Methode des quantitativen Nachweises der Para-Aminosalicyls�ure im Harn
1951
Mitteilung eines einfachen quantitativen Nachweises der PAS im Urin bei Kranken, die mit diesem Medikament behandelt werden. Auf mit Ehrlich-Reagens prapariertem Filtrierpapier wird PAS-haltiger Urin aufgetropft. Der entstehende Farbniederschlag ist je nach PAS-Gehalt mehr oder weniger gelb bis braun-rot verfarbt. Diese Farbung wird mit selbst angefertigten Testfarbungen verglichen und der PAS-Gehalt in der ausgeschiedenen Urinmenge bestimmt.
