The concept of cultural competence has become ubiquitous in human services language and settings. Though the literature from various disciplines is replete with discussions on the topic, there still exists much disagreement regarding the definition of cultural competence as well as how to operationalize, test, and apply concepts related to cultural competence in social service settings. A related issue stems from debate regarding whether cultural competence is a theory, model, paradigm, framework, or perspective. Though cultural competence has been referred to as a theory by some scholars from different disciplines (e.g., Lum, 2005; Blue, Thiedke, Chessman, Kern, & Keller, 2005; Wu & Martinez, 2006), there is still disagreement about whether the concepts related to cultural competence actually meet the criteria for a theory and, consequently, whether they can be used to generate hypotheses and allow for independent observations that can be used to continue building theory, conduct empirical research, and provide evidenced-based practice implications. The authors join in this theory debate through an analysis of the elements of theory and conclude that it has better fit with the definition of social perspective than it does social theory.

Order Preference

Total control target for pollution emission is the principal mode in China within a long period in the future, and therefore pollution reduction allocation is a key issue for pollution control. This paper describes an integrated theory and methodology of industrial pollution reduction among administrative regions, including 1) three basic principles, 2) an index system, 3) an innovative optimal allocation model based on combination of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Genetic Algorithms (GA), and 4) an empirical research on allocation of industrial chemical oxygen demand (COD) reduction of 17 sub-regions of Shandong province in China. The results of the empirical research were conformed to the basis of sustainable development. This integrated theory and methodology are applied but not limited in pollution reduction, having broad application prospect in the optimization of the use of environmental resources.

Optimal Type

Children who use cochlear implants experience significant difficulty hearing speech in the presence of background noise, such as in the classroom. To address these difficulties, audiologists often recommend frequency-modulated (FM) systems for children with cochlear implants. The purpose of this article is to examine current empirical research in the area of FM systems and cochlear implants. Discussion topics will include selecting the optimal type of FM receiver, benefits of binaural FM-system input, importance of DAI receiver-gain settings, and effects of speech-processor programming on speech recognition. FM systems significantly improve the signal-to-noise ratio at the child's ear through the use of three types of FM receivers: mounted speakers, desktop speakers, or direct-audio input (DAI). This discussion will aid audiologists in making evidence-based recommendations for children using cochlear implants and FM systems.

The Impact

For the effective use of modern tools, the inherent visuo-motor transformation needs to be mastered. The successful adjustment to and learning of these transformations crucially depends on practice conditions, particularly on the type of visual feedback during practice. Here, a review about empirical research exploring the influence of continuous and terminal visual feedback during practice on the mastery of visuo-motor transformations is provided. Two studies investigating the impact of the type of visual feedback on either direction-dependent visuo-motor gains or the complex visuo-motor transformation of a virtual two-sided lever are presented in more detail. The findings of these studies indicate that the continuous availability of visual feedback supports performance when closed-loop control is possible, but impairs performance when visual input is no longer available. Different approaches to explain these performance differences due to the type of visual feedback during practice are considered. For example, these differences could reflect a process of re-optimization of motor planning in a novel environment or represent effects of the specificity of practice. Furthermore, differences in the allocation of attention during movements with terminal and continuous visual feedback could account for the observed differences.

Abstract. Which data to analyze, and how, are fundamental questions of all empirical research. As there are always numerous flexibilities in data-analytic decisions (a “garden of forking paths”), this poses perennial problems to all empirical research. Specification-curve analysis and multiverse analysis have recently been proposed as solutions to these issues. Building on the structural analogies between primary data analysis and meta-analysis, we transform and adapt these approaches to the meta-analytic level, in tandem with combinatorial meta-analysis. We explain the rationale of this idea, suggest descriptive and inferential statistical procedures, as well as graphical displays, provide code for meta-analytic practitioners to generate and use these, and present a fully worked real example from digit ratio (2D:4D) research, totaling 1,592 meta-analytic specifications. Specification-curve and multiverse meta-analysis holds promise to resolve conflicting meta-analyses, contested evidence, controversial empirical literatures, and polarized research, and to mitigate the associated detrimental effects of these phenomena on research progress.
