The human body has dedicated receptors for sensing temperature and touch, but not wetness. How then is wetness perceived? To test if wetness perception arises from the sensory integration of touch and temperature, and to quantify its measurement in humans, we designed a wetness perception monitor (WPM) which enabled variation of temperature at the fingertips of participants while measuring the pressure exerted on a test surface in the controlled environment of a moisture-free chamber. Thirty randomly selected adults (18+ years) were tested for their perception of dampness/wetness using the WPM. Our data suggest that humans perceive dampness and wetness at average temperatures of 22 ± 0.4°C and 18 ± 0.5°C, respectively, and these sensations are extinguished at temperatures below 16 ± 1°C. Measurements were obtained at an average tactile pressure of 1.5 ± 0.3 kPa. Young adults (18–35 years) sensed wetness at significantly higher temperatures than middle-aged adults (36–55 years) or mature adults (56+ years), who sensed wetness at similar temperatures. We found a surprising sex difference in wetness perception, with females sensing wetness at higher temperatures than males. When the data were screened for outliers, we found that participants whose readings were outside normal ranges, self-reported sensory deficits suggesting that wetness perception could potentially be used as a noninvasive biomarker.

: Point-of-care (POC) testing decentralizes the diagnostic tests to the sites near the patient. Many POC tests rely microfluidic platforms for sample-to-answer analysis. Compared to other microfluidic systems, magnetic digital microfluidics demonstrate compelling advantages for POC diagnostics. In this review, we have examined the capability of magnetic digital microfluidics-based POC diagnostic platforms. More importantly, we have categorized POC settings into three classes based on “where is the point”, “who to care” and “how to test”, and evaluated the suitability of magnetic digital microfluidics in various POC settings. Furthermore, we have addressed other technical issues associated with POC testing such as controlled environment, sample-system interface, system integration and information connectivity. We hope this review would provide a guideline for the future development of magnetic digital microfluidics-based platforms for POC testing.

Improvement Strategies

The education based on simulation is an educationalstrategy where students learn from their errors, developing skills, knowledge, competences,etc. in a controlled environment. During the process of teaching by simulation, it is necessaryto execute various types of assessments (diagnostic, summative, formative) in order tomake adjustments or changes in the educational process of the students, therefore identifying areas of opportunity for improvement. With the simulation, different processes can be taught, like interprofessionalism and collaborative work. Nowadays, there is a major concern for added safety and the quality of care for the patients and their families. Therefore, a WHO study group determined the basic interprofessional competences, and has been given the task of disseminating and promoting interprofessional education. Some educational institutions in the US, Canada and Europe have integrated interprofessional and collaborative work in simulation practices. All the activity by simulation must be evaluated in order to provide feedback to the participants and establish improvement strategies. The assessment of the interprofessional work focuses on the evaluation of common skills and competencies among various health professionals.

Close Cooperation

The case study presented in this chapter discusses the design and implementation of an online platform, “come_NET,” in the context of intercultural computer clubs in Germany. This tool was built in close cooperation with the children and adult computer club participants. It was designed to foster the sharing of ideas and experiences across distances, support collaboration, and make skills and expertise accessible to others in the local neighborhood contexts. In particular, the participatory-design process involving the children in the computer clubs fostered a profound understanding of the platform structure and functionalities. The study results show how younger children in particular were able to benefit, as the closed nature of the platform enabled them to gather experience as users of social media, but in a safe and controlled environment.

Political Persuasion

Political endorsements (recommendations about which candidate or policy to support) are ubiquitous in political contexts. They may come from political parties, interest groups, politicians, or even celebrities. Can uninformed citizens identify endorsers who share their interests and use their recommendations as substitutes for detailed political information? This chapter surveys the literature on the persuasion effects of political endorsements. It first provides an overview of theoretical models that examine how political endorsements affect citizens’ choices. Then, it describes a seminal observational study of how endorsements affect political persuasion. It next discusses experimental research that assesses the effects of endorsements. It emphasizes that experiments are particularly useful for identifying when political endorsements will persuade citizens because they allow scholars to manipulate the conditions that theoretical models identify in a carefully controlled environment. It concludes by discussing open questions about the effects of political endorsements and describing how ongoing research addresses them.

AbstractRising temperatures and changing precipitation patterns will affect agricultural production substantially, exposing crops to extended and more intense periods of stress. Therefore, breeding of varieties adapted to the constantly changing conditions is pivotal to enable a quantitatively and qualitatively adequate crop production despite the negative effects of climate change. As it is not yet possible to select for adaptation to future climate scenarios in the field, simulations of future conditions in controlled-environment (CE) phenotyping facilities contribute to the understanding of the plant response to special stress conditions and help breeders to select ideal genotypes which cope with future conditions. CE phenotyping facilities enable the collection of traits that are not easy to measure under field conditions and the assessment of a plant‘s phenotype under repeatable, clearly defined environmental conditions using automated, non-invasive, high-throughput methods. However, extrapolation and translation of results obtained under controlled environments to field environments is ambiguous. This review outlines the opportunities and challenges of phenotyping approaches under controlled environments complementary to conventional field trials. It gives an overview on general principles and introduces existing phenotyping facilities that take up the challenge of obtaining reliable and robust phenotypic data on climate response traits to support breeding of climate-adapted crops.
