Eating behaviour can vary with age, experience, and gender, as well as food hardness. This variation can contribute to intraspecific dietary differences and may result in variable definitions of optimal foraging and decreased intraspecific competition. We quantified feeding behaviour of insectivorous bats eating hard and soft mealworm-based food items based on the bats’ ability to consume and manipulate food items, consumption time, chew frequency, and total chews to consume. Adult Myotis lucifugus (LeConte, 1831) were more successful at both consuming and manipulating mealworms and consumed mealworms more quickly, with greater chew frequency and in fewer chews, than did subadults. Adults chewed mealworm viscera more frequently than did subadults but showed no differences in the other variables. Adult Eptesicus fuscus (Beauvois, 1796) consumed mealworms more quickly and with fewer chews than did subadults but showed no differences in the other variables. There were no differences between adult and subadult E. fuscus when consuming mealworm viscera. Male and female M. lucifugus did not differ significantly when eating either mealworms or mealworm viscera. There was no change in subadult consumption time of mealworms over the summer. Age-based differences in eating abilities may play a role in defining optimal foraging and dietary composition in insectivorous bats.

This study followed two objectives: it primarily investigated the types of discourse markers (DMs) used in thespoken language of Iranian advanced EFL learners, and then explored the possible impact of gender on theparticipants’ use of DMs. To this end, 40 male and female EFL learners selected from an English language instituteparticipated in this study. The data were gathered through class observations. The researchers used Fraser’staxonomy of DMs and Fung’s category of interpersonal DMs as the theoretical framework of the study. To analyzethe data descriptive and inferential statistics were used. Results of the frequency test revealed that “and” was themost commonly used elaborative DM, whereas “but” was the most frequent contrastive DM. “Because” and “by theway” were respectively the only reason and topic-related DMs used by the participants, while “sure” was the mostfrequent interpersonal DM. In addition, results of the chi-square test revealed that learners significantly employedinterpersonal DMs more than the other sub-classes of DMs. Concerning the role of gender in the use of DMs, resultsdemonstrated that females significantly used more DMs compared with the males.

Purpose: To analyze the pacing profiles of the world’s top 800-m annual performances between 2010 and 2016, comparing men’s and women’s strategies. Methods: A total of 142 performances were characterized for overall race times and 0-to-200-m, 200-to-400-m, 400-to-600-m, and 600-to-800-m split times using available footage from YouTube. Only the best annual performance for each athlete was considered. Overall race and split speed were calculated so that each lap speed could be expressed as a percentage of the mean race speed. Results: The mean speed of the men’s 800-m was 7.73 (0.06) m·s−1, with the 0-to-200-m split faster than the others. After the first split, the speed decreased significantly during the 3 subsequent splits (P < .001). The mean speed of the women’s 800-m was 6.77 (0.05) m·s−1, with a significative variation in speed during the race (P < .001). The first split was faster than the others (P < .001). During the rest of the race, speed was almost constant, and no difference was observed between the other splits. Comparison between men and women revealed that there was an interaction between split and gender (P < .001), showing a different pacing behavior in 800-m competitions. Conclusions: The world’s best 800-m performances revealed an important difference in the pacing profile between men and women. Tactics could play a greater role in this difference, but physiological and behavioral characteristics are likely also important.

The aim of the present study was to find out whether age and gender have an influence on the sexual attitudes of people. The following components of sexual attitude were studied namely: Attitude towards lesbianism and homosexuality. The sample consisted of 100 subjects in which 50 were from the age group of 18-28 years further divided equally with respect to gender (25-male, 25-female) and the other 50 in the age group of 50-60 years similarly divided into male and female. 2×2 Factorial design was used as the research design for the present study. The sample was first divided in two groups on the basis of age and then further on the basis of gender. Personal data sheet and a questionnaire titled ‘Sexual Attitude Scale’ developed by Amit Abraham was used for data collection. Gathered data was calculated and analysed by F-test (ANOVA). The results revealed that subjects in the age group of 18-28 years had a favourable sexual attitude and 50-60 years had an unfavourable sexual attitude. On the basis of gender, males showed a favourable sexual attitude over females. While studying the interaction of age and gender on sexual attitudes it was found that males in the age group of 18-28 years had the most favourable sexual attitude whereas the females in the age groups of 50-60 years had the least favourable sexual attitude.

Kelantan State recorded the highest in terms of acreage for tobacco plantation with consists of77.94 %. Tobacco plantation was known to be the most risky job among Kelantanese due toextensive usage of pesticide and fertilizer. This study was conducted to identify the differencesbetween male and female in Best Management Practices (BMPs) for tobacco cultivators inBachok as well as to relate it with the fertilizers and pesticides related diseases in Bachok District,Kelantan, Malaysia. The results revealed that, the correlation between wearing proper PPEs andgender (p<0.05) and between chronic diseases and gender (p<0.05) were significant. Femalecultivators they are more concern about their health compared to the male. Meanwhile, 49% ofmale and 25 % of female cultivators claimed that they had the acute illnesses. On the other hand,the health data in 2010 obtained from the Bachok District Health Center showed that, acute upperrespiratory tract infections (19,641 cases) and other disease of the respiratory system (16,484cases) recorded the highest cases followed by dermatitis (5,300 cases), conjunctivitis (2,582cases), urticarial (1,689 cases), impetigo (1,387 cases), poisonings (548 cases), asthma (450cases) and bronchitis (8 cases). It could be concluded that, the female planter are more healthconscious and it is revealed in this findings where they wore PPEs at all times when dealing withchemicals.

AbstractWe empirically examine the strategic importance of the choices of the first person ordering, that is, the leader, for the decisions made and money spent by other commensals at a restaurant table. Our aim is to study the similarity of orders—in terms of dishes, drinks, and prices—among the table leader and the other commensals. The empirical results reveal that table leaders, both male and female, exert a considerable influence on the choices made by other diners. We analyze the differences arising when males and females act as table leaders. (JEL Classifications: D12, D91)

Studies have established gender-based variations in human’s use of language, particularly in the areas of grammar and lexis.  This study investigated language use in prose-works involving male and female writers, aimed at finding out whether there were grammar related variations in the use of language by the selected male and female writers.  The framework adopted for analysis was the Hallidayan notion of Clause Complexes and Embedded Clauses and how writers made conscious choices from the grammar of logical meaning in their different narratives.  Five male-authored and five female-authored prose-works were selected for the study.  A part of each prose-work containing fifty (50) consecutive sentences was randomly excised and analysed into clause simplexes, clause complexes and embedded clauses, and the frequencies of these clause types were determined.  The result clearly showed that the male authors had higher frequencies of clause complexes than simplexes; whereas the female writers had lower frequencies of complexes but higher frequencies of simplexes.  It also showed higher frequencies of embedded clauses in male-authored texts than in female-authored ones. The results therefore suggested that narratives of male writers tend to be more syntactically complex (because of higher frequencies of clustered clauses and varying functional and semantic relationships among component clauses) and semantically complex (because of a much tighter integration of meanings through clause clustering and embedding).  The narratives of female writers, on the other hand, tend to be syntactically and semantically simple (with higher use of simplexes, but less use of complexes and embedded clauses).Keywords: Grammar, gender, clause complexes, clause simplexes, embedded clauses.

Speech Naturalness

Purpose The purpose of this study was to investigate how speech naturalness relates to masculinity–femininity and gender identification (accuracy and reaction time) for cisgender male and female speakers as well as transmasculine and transfeminine speakers. Method Stimuli included spontaneous speech samples from 20 speakers who are transgender (10 transmasculine and 10 transfeminine) and 20 speakers who are cisgender (10 male and 10 female). Fifty-two listeners completed three tasks: a two-alternative forced-choice gender identification task, a speech naturalness rating task, and a masculinity/femininity rating task. Results Transfeminine and transmasculine speakers were rated as significantly less natural sounding than cisgender speakers. Speakers rated as less natural took longer to identify and were identified less accurately in the gender identification task; furthermore, they were rated as less prototypically masculine/feminine. Conclusions Perceptual speech naturalness for both transfeminine and transmasculine speakers is strongly associated with gender cues in spontaneous speech. Training to align a speaker's voice with their gender identity may concurrently improve perceptual speech naturalness. Supplemental Material https://doi.org/10.23641/asha.12543158

Degree Of Association

Abstract. The introduction of the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998 ) has stimulated numerous research activities. The IAT is supposed to measure the degree of association between concepts. Instances have to be assigned to these concepts by pressing appropriate keys as quickly as possible. The reaction time difference between certain conditions, termed the IAT effect, is used as an indicator of the degree of the concepts’ association. We tested the hypothesis that the degree of association between one concept (or category) and the instances of the other presented concept also influences reaction times. In our experiment, the instances in the target categories, male and female names, were kept constant. The adjectives in the evaluative categories were manipulated: Either the pleasant adjectives were female-associated and the unpleasant adjectives were male-associated, or vice versa. These stereotypic associations were indeed found to exert a substantial influence on the size of the IAT effect. This finding casts doubt on the assumption that the IAT effect may be interpreted as a pure measure of the degree of association between concepts.

Abstract. People believe women are more emotional than men but it remains unclear to what extent such emotion stereotypes affect leadership perceptions. Extending the think manager-think male paradigm ( Schein, 1973 ), we examined the similarity of emotion expression descriptions of women, men, and managers. In a field-based online experiment, 1,098 participants (male and female managers and employees) rated one of seven target groups on 17 emotions: men or women (in general, managers, or successful managers), or successful managers. Men in general are described as more similar to successful managers in emotion expression than are women in general. Only with the label manager or successful manager do women-successful manager similarities on emotion expression increase. These emotion stereotypes might hinder women’s leadership success.
