Hot topics in research: preventive neuroradiology in brain aging and cognitive decline

Preventive neuroradiology is a new concept supported by growing literature. The main rationale of preventive neuroradiology is the application of multimodal brain imaging toward early and subclinical detection of brain disease and subsequent preventive actions through identification of modifiable risk factors. An insightful example of this is in the area of age-related cognitive decline, mild cognitive impairment, and dementia with potentially modifiable risk factors such as obesity, diet, sleep, hypertension, diabetes, depression, supplementation, smoking, and physical activity. In studying this link between lifestyle and cognitive decline, brain imaging markers may be instrumental as quantitative measures or even indicators of early disease. The purpose of this article is to provide an overview of the major studies reflecting how lifestyle factors affect the brain and cognition aging. In this hot topics review, we will specifically focus on obesity and physical activity.

What is needed to make research on the psychosocial work environment and health more meaningful? Reflections and missed opportunities in IPD debates

We identify issues that have been overlooked in the debates about the work of the IPD-Work Consortium. These include the need for objective cut-points for psychosocial work stress exposures and better conceptual models of how psychosocial work exposures, health behaviors, obesity, and enduring health conditions are related.

Oxidative dissolution of research-grade minerals by Thiobacillus ferrooxidans and Thiobacillus thiooxidans

Solution- and solid-phase changes associated with galena (PbS) and sphalerite (ZnS) oxidation by T. ferrooxidans and T. thiooxidans, were determined. In experiments with galena, anglesite (PbSO4) was detected as a solid-phase product in biotic and abiotic experiments. In T. ferrooxidans cultures supplemented with FeSO4, jarosite [MFe3 (SO4)(2) (OH)(6)] was also detected as a new solid phase product, whereas SO was not detected in the residues. In sphalerite experiments, minor amounts of SO accumulated in FeSO4-amended sphalerite media with or without T. ferrooxidans or T. thiooxidans. Jarosite was only detected in T. ferrooxidans culture with FeSO4. By comparison with T. thiooxidans, T. ferrooxidans was more efficient in the oxidation of galena and sphalerite.

New product development in brazilian technology-based small and medium enterprises

This article examines new product development (NPD) in small and medium-sized Brazilian enterprises (SMEs) in two technology-based industries: medical devices and process control automation devices. A conceptual model that categorizes factors that contribute to the success of a new product was established. The data were collected from a sample of 62 Brazilian SMEs. The conceptual model was tested to examine the relationships between NPD practices and new product success. Data analysis reveals that new product success in medical device companies is related to organizational characteristics such as NPD proficiency and marketing skills; while in process control automation device companies, they deal in a large degree with product differentiation, innovation and capability to analyze the targeted market. Due to the relatively small sample size, caution should be exercised when interpreting the results.

Using Three Dimensional Motion Capture Technology to Describe and Assess Piano Technique: A Case Study

The purpose of the study was to examine any differences that exist in the quality of motions employed by pianists when they are sight-reading versus performing repertoire. A secondary question of interest was whether or not an improvement in the efficiency of motion could be observed between two sight-reading trials of the same musical excerpt. While data analysis for the full study is ongoing, the following results from a case study are illustrative.

Research for sustainable development: Foundations, experiences, and perspectives

Research for Sustainable Development is based on the experiences of a decade of inter- and transdisciplinary research in partnership in nine regions of the world. It presents 29 articles in which interdisciplinary teams reflect on the foundations of sustainability-oriented research, propose and illustrate concrete concepts, tools, and approaches to overcome the challenges of such research, and show how research practice related to specific issues of sustainable development has led to new thematic and methodological insights. The book seeks to stimulate the advancement of research towards more relevant, scientifically sound, and concrete contributions to realising the vision of sustainable development.
