Helium pressure effects on avoidance behavior in rats breathing high nitrogen pressures.

3 rats given avoidance training and then exposed to 7, 13, and 19 ATA breathing nitrogen, then to 25, 31, and 37 ATA breathing helium, showed increased avoidance response rates above established baselines to 19 ATA followed by a decline. Narcotic effects of nitrogen were not reduced differentially by addition of helium.     

Sex-role traditionalism and fear of success

In the present study 33 adult women completed Horner's measure of fear of success, filled out a questionnaire that tapped sex-role traditionalism and negative attitudes toward the women's liberation movement, and answered questions concerning their political beliefs and educational backgrounds. In line with some of Horner's contentions, it was found that fear of success is more common among nontraditional women — those who favor the women's movement, have more education, and hold liberal or radical political beliefs. Fear of success is not a correlate of traditional femininity but rather a sign of conflict experienced by ambitious, nontraditional women. Implications and further questions are discussed.     

Language as a determinant of Welsh identity

The study was designed, using the ?matched-guise' technique, to determine how different groups of Welshmen perceive members of their own national group who use various linguistic codes. Three matched groups of adult Welsh Ss were used: Bilinguals, those who were learning Welsh and those who could not speak Welsh and were not learning it either. These Ss were asked to evaluate on 22 scales the personalities of various Welsh speakers they heard reading the same passage of prose on tape. Essentially, the stimulus tape consisted of two male bilinguals reading the passage once each in Welsh, in English with a Welsh accent and in English with an RP accent. It was found, despite the fact that the groups differed in their language skills and self-perceived Welshness, that Ss as a whole upgraded the bilingual speakers on most traits. Indeed, the RP speakers were evaluated most favourably on only one trait - self-confidence. It was suggested that language to a large extent serves as a symbol of Welsh identity, and the results were discussed in relation to how other ethnic groups appear to view their own linguistic codes.     

Working with Research Integrity—Guidance for Research Performing Organisations: The Bonn PRINTEGER Statement

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:

1. § 1.
   Providing information about research integrity
    
2. § 2.
   Providing education, training and mentoring
    
3. § 3.
   Strengthening a research integrity culture
    
4. § 4.
   Facilitating open dialogue
    
5. § 5.
   Wise incentive management
    
6. § 6.
   Implementing quality assurance procedures
    
7. § 7.
   Improving the work environment and work satisfaction
    
8. § 8.
   Increasing transparency of misconduct cases
    
9. § 9.
   Opening up research
    
10. § 10.
    Implementing safe and effective whistle-blowing channels
     
11. § 11.
    Protecting the alleged perpetrators
     
12. § 12.
    Establishing a research integrity committee and appointing an ombudsperson
     
13. § 13.
    Making explicit the applicable standards for research integrity
     

     

Game-theoretical semantics for Peirce's existential graphs

In this paper, a game-theoretical semantics is developed for the so-called alpha part of Charles S. Peirce's System of Existential Graphs of 1896. This alpha part is that portion of Peirce's graphs that corresponds to propositional logic. The paper both expounds a game-theoretical semantics for the graphs that seems close to Peirce's own intentions and proves for the alpha part of the graphs that this semantics is adequate.     

The use of digital rheoplethysmography for the study of psychogenic and neurogenic factors in man

The use of the RPG in the qualitative and quantitative study of the state of the intact digital vasculature of intact man is illustrated and emphasized. Rheoplethysmography is the only method for quantitatively recording continuously and simultaneously the volumes and rates of inflow, outflow and the differences between inflow and outflow and the rate of basal blood flow in the digits of intact man or in any organ or tissue that can be isolated in a plethysmographic cup. The effects of psychogenic and neurogenic factors on the peripheral circulation of man were studied with the RPG, and the results demonstrate how useful this method is for such studies of the fingertip.     

Becoming team players: team members' mastery of teamwork knowledge as a predictor of team task proficiency and observed teamwork effectiveness

The authors explored the idea that teams consisting of members who, on average, demonstrate greater mastery of relevant teamwork knowledge will demonstrate greater task proficiency and observed teamwork effectiveness. In particular, the authors posited that team members' mastery of designated teamwork knowledge predicts better team task proficiency and higher observer ratings of effective teamwork, even while controlling for team task proficiency. The authors investigated these hypotheses by developing a structural model and testing it with field data from 92 teams (1,158 team members) in a United States Air Force officer development program focusing on a transportable set of teamwork competencies. The authors obtained proficiency scores on 3 different types of team tasks as well as ratings of effective teamwork from observers. The empirical model supported the authors' hypotheses.     

Re-dressing helping attire: methodological and interpretive issues

Using a study by Wilson and Kennedy in 2006 as a springboard, methodological and interpretive issues associated with helping people dressed differently and at various geographic locations are suggested. A plea for exploring more of the dynamics of helping as a communicative process is tabled.
