This study aimed to evaluate potential gender differences in recovery of power output during repeated all-out cycling exercise. Twenty men and thirteen women performed four series of two sprints (Sp1 and Sp2) of 8 s, separated by 15-, 30-, 60-, and 120-s recovery. Peak power (Ppeak), power at the 8th s, total mechanical work, and time to Ppeak were calculated for each sprint. Ppeak and mechanical work decreased significantly between Sp1 and Sp2 after 15-s recovery in both men (-6.4 and -9.4%, respectively) and women (-7.4 and -6.8%, respectively). Time to Ppeak did not change between recovery durations, but women reached their peak power more slowly than men (on average 5.15 ± 1.2 and 3.8 ± 1.2 s, respectively; P < 0.01). During Sp1 and Sp2, linear regressions from Ppeak to power at the 8th s showed a greater power decrease (%Ppeak) in women compared with men ( P < 0.05). In conclusion, patterns of power output recovery between two consecutive short bouts were similar in men and women, despite lower overall performance and greater fatigability during sprints in women.

We tested the hypothesis that sympathetic vasoconstrictor nerve activity to nonactive skeletal muscle (MSNA) decreases immediately before and remains suppressed during initiation of conventional large muscle upright dynamic exercise in humans. In 11 healthy young subjects, adequate recordings of MSNA from the radial nerve in the arm were obtained during upright seated rest (control) and throughout 1 min of leg-cycling exercise at one or more submaximal workloads (range 33–266 W; approximately 10–80% of peak power output). MSNA was analyzed during four consecutive time intervals; control, preparation for cycling (end of control to onset of pedal movement), initiation of cycling (onset of pedal movement to attainment of target power output), and the initial 60 s of cycling at target power output. MSNA decreased (P < 0.05) abruptly and markedly in all subjects [to 19 +/- 4% (SE) of control levels] during the preparation period before the 33-W load and remained suppressed throughout the period of initiation of cycling in 8 of 11 subjects; MSNA increased during the initiation period in three subjects in whom diastolic arterial pressure fell below control levels. This general pattern was observed at all loads. MSNA remained at or below control levels throughout the 1 min of cycling exercise at 33–166 W. MSNA increased above control levels during the latter portion of the 1 min of cycling only at loads > or = 60% of peak power output.(ABSTRACT TRUNCATED AT 250 WORDS)

Men and women exiting the correctional system represent a population at high risk for mental health problems, and the body of research on the mental health needs of former prisoners is growing. These mental health problems pose challenges for individuals at every stage of the criminal justice process, from arrest to incarceration to reentry and reintegration. This article examines the mental health status and gender differences among a sample of 352 men and women leaving confinement and the role that mental health problems played in shaping their reentry outcomes using data collected between 2002 and 2005. In the year after leaving prison, men and women with mental health problems reported worse health indicators and less satisfactory social factors, such as employment, housing, and family support. The article concludes with a discussion of recommendations for improved policy and practice for assisting former prisoners with mental health problems during reintegration.

Online dating is becoming an increasingly used method for meeting significant others. As the research of lying behavior has advanced so has the technique of detecting the act of lying, especially in the online environment where deception is more likely to happen. The aim of this chapter is to simplify the perception of lying behavior to the general population and examine gender differences of lying behavior, namely, to verify whether one can observe a statistically significant difference in the speech behavior and exploitation of lying cues among men and women. The study shows correlation between gender and deception in online environment.

AbstractGender differences are often reported in spatial abilities, most of the times favouring men. Even during wayfinding, which requires planning and decision-making, such as choosing roads to take or shortcuts, men are in general better and faster than women. Although different interpretations have been proposed to explain men’s advantage in navigation, no study has explored the possibility that it could be due to men’s better travel planning ability. This latter has been recently identified as a distinct kind of planning that allows implementing an efficient navigational strategy in accordance with the environmental features. Therefore, the present study was aimed at investigating gender differences in travel planning ability. We compared men and women in performing the Key Search Task that requires to implement a strategy to search for a lost object in a wide imagined space. Results showed that men outperform women in both the overall performance and in some specific indexes of the total score. Men had a better travel planning ability with respect to women, outperforming women in configuring the planned strategy and choosing the best point to enter the imagined field. Therefore, men seem to plan the best navigational strategy and appear more cognitively flexible than women in adapting the strategy at the environmental features. The two genders did not differ in the time spent to solve the task. This finding suggests that differences in travel planning skills can contribute in explaining gender differences in wayfinding and spatial orientation.

The stories we tell about our origins can shape how we think and act – helping us make sense of and communicate who we have “become” over time. To better understand the role that origin stories play in individuals’ work lives, we explore how 92 men and women leaders make sense of “becoming” a leader (origin stories) and “doing” leadership (enactment stories). We find that, despite the uniqueness of their experiences, their narratives converge around four frames, being, engaging, performing, and accepting, through which they understand, articulate, and enact their leader identities. We theorize that these narrative frames serve as sensemaking and identity work devices which allow them to create temporal coherence, validate their leader identity claims, and offer them behavioral scripts. Our findings also unearth key gender differences in the use of these frames, in that men used the performing frame more often and women tended toward the engaging frame. These findings provide novel insights into the ways in which the gendered context of leadership becomes embedded in leaders’ understandings of who they are and what they intend to do in their roles. We discuss the theoretical implications of our findings on scholarly conversations around identity, leadership, and gender.

Aims: Women have much higher rates of sickness absence than men, but the causes of the difference are not well understood. This study examines whether managers have more lenient attitudes towards women’s than towards men’s absence, as this might contribute to higher rates of sickness absence among women. Differences between managers and other employees are also assessed. Methods: Vignettes were used to measure attitudes towards the legitimacy of sickness absence. The vignettes consisted of brief case descriptions of individuals considering asking their physicians for sick leave, with information about the medical condition (mainly taken from the descriptions in ICPC-2), occupation and gender. Respondents judged how appropriate sickness absence was in each case. Quota sampling was used, and the effective sample size was 899 managers and 1396 other employees, with each respondent evaluating either four or six vignettes. Generalised ordinal logistic regression was used. Results: The gender of the vignette person had no effect on the managers’ evaluations of the appropriateness of sickness absence. Irrespective of the gender of the vignette person, however, managers were generally more restrictive than non-managers. Conclusions: Different attitudes on the part of managers towards sickness absence in men and women do not seem to contribute to gender differences in sickness absence, but managers are generally more restrictive compared to non-managerial employees.

In the ITC cross-cultural literature, we often talk about the differences among peoples and how their respective culture and history may affect their adoption and preference usage patterns of ITC. However, do we really need to look that far to find such cross-cultural differences? Considering language is one of the major defining attributes of culture, this article takes a sociolinguistic approach to argue that there is also a cross-cultural aspect to ITC adoption within the same culture. Sociolinguists have claimed for years that, to a large extent, the communication between men and women, even within the supposedly same culture, has such characteristics because men and women communicate with different underlying social objectives and so their communication patterns are very different. This article examines this sociolinguistic perspective in the context of online courses. A key finding is that although the stage is set to smother cultural and gender differences if participants wish to do so through ITC, gender based cultural patterns still emerge. These differences were actually strong enough to allow us to significantly identify the gender of the student, despite the gender neutral context of the course discussions. Implications for ITC, in general, in view of this Vive la Différence, are discussed.
