Transport Mobility

ABSTRACTAmong the societal and health challenges of population ageing is the continued transport mobility of older people who retain their driving licence, especially in highly car-dependent societies. While issues surrounding loss of a driving licence have been researched, less attention has been paid to variations in physical travel by mode among the growing proportion of older people who retain their driving licence. It is unclear how much they reduce their driving with age, the degree to which they replace driving with other modes of transport, and how this varies by age and gender. This paper reports research conducted in the state of Queensland, Australia, with a sample of 295 older drivers (>60 years). Time spent driving is considerably greater than time spent as a passenger or walking across age groups and genders. A decline in travel time as a driver with increasing age is not redressed by increases in travel as a passenger or pedestrian. The patterns differ by gender, most likely reflecting demographic and social factors. Given the expected considerable increase in the number of older women in particular, and their reported preference not to drive alone, there are implications for policies and programmes that are relevant to other car-dependent settings. There are also implications for the health of older drivers, since levels of walking are comparatively low.

This study aims to investigate the linguistic and social factors influencing the realisation of the initial Modern Arabic verb form CaC-in Kuwaiti Arabic (KA). While very few studies have examined the sociolinguistic variation of the initial verb form CaC-in KA, this variable has been found to be produced in the speech of two Kuwaiti communities from different ethnic backgrounds, namely Najdi (from Saudi Arabia originally) and Ajami (from Iran originally). The aim is to analyse the realisation of CaC-forms as a reflection of ethnicity, age and gender in KA. Data were collected from 48 male and female Kuwaiti speakers from two ethnicities (Najdi and Ajami), three age groups (chosen according to relevant milestones in the history of Kuwait). Two main techniques were implemented to collect data in this study, namely spontaneous and controlled data. The investigation showed that there were significant differences in the realisation of the initial verb form CaC-in the two ethnicities and across age and gender. The study also showed that the CaC-form had less prestige than did the CiC-form, which is mostly found in the Najdi variety.

The objective of the research described here was to study the effects of the offset between opposing left-turn lanes on the turning performance of drivers with respect to driver age and gender. Left-turn performance of 100 subjects within three age groups (25–45, 65–74, and 75+ years old) was evaluated under normal driving conditions at four intersections of different left-turn offset configurations. The results indicate that driver performance can be adversely affected by offsets that are much less (i.e., more negative) than the negative 0.9-m offset. Such large negative offsets significantly increase the size of the critical gaps of drivers turning left and also seem to increase the likelihood of conflicts between left turns and opposing through traffic. Large negative offsets may be particularly troublesome for older drivers and women drivers, who are less likely to position their vehicles within the intersection to see beyond vehicles in the opposing left-turn lane. Surprisingly, driver perceptions of the level of comfort and degree of difficulty were not found to improve with the increased sight distance provided by larger (i.e., more positive) offsets. The 1.8-m positive offset was associated with a lower level of comfort and a higher degree of difficulty perceived by drivers making left turns than the 0.9-m negative offset, which provided less sight distance. This may have been because the 0.9-m negative offset is much more common than the 1.8-m positive offset.

AbstractThis description of relations between grandparents and grandchildren in a rural Ghanaian community argues that the quality of these relations varies according to age and gender. Literature on African kinship has almost entirely focused on very young grandchildren. This article draws attention to changes that occur when those children grow into adolescents and adults. Grandchildren—both young and old—speak respectfully about their grandparents, but older people regret that their grandchildren do not come to them for advice once they have grown up. Older men seem more ‘neglected’ by their grandchildren than older women. The second argument is about performance: respect, affection and relatedness between grandparents and grandchildren are demonstrated in public even when their ‘contents’ have dwindled. The article is based on anthropological fieldwork over a period of almost ten years.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

The role of children in Merovingian society has long been downplayed, and the study of their graves and bones has long been neglected. However, during the past fifteen years, archaeologists have shown growing interest in the place of children in Merovingian society. Nonetheless, this research has not been without challenges linked to the nature of the biological and material remains. Recent analysis of 315 children’s graves from four Merovingian cemeteries in northern Gaul (sixth to seventh centuries) allows us to understand the modalities of burial ritual for children. A new method for classifying children into social age groups shows that the type, quality, quantity, and diversity of grave goods were directly correlated with the age of the deceased. They increased from the age of eight and particularly around the time of puberty. This study discusses the role of age and gender in the construction and expression of social identity during childhood in the Merovingian period.

The strong overlap of personality traits discussed under the label of “dark personality” (e.g., psychopathy, spitefulness, moral disengagement) endorses a common framework for socially aversive traits over and beyond the dark triad. Despite the rapidly growing research on socially aversive traits, there is a lack of studies addressing age-associated differences in these traits. In the present study ( N = 12,501), we investigated the structure of the D Factor of Personality across age and gender using local structural equation modeling, thereby expressing the model parameters as a quasi-continuous, nonparametric function of age. Specifically, we evaluated loadings, reliabilities, factor (co-)variances, and means across 35 locally weighted age groups (from 20 to 54 years), separately for females and males. Results indicated that measurement models were highly stable, thereby supporting the conceptualization of the D factor independent of age and gender. Men exhibited uniformly higher latent means than females and all latent means decreased with increasing age. Overall, D and its themes were invariant across age and gender. Therefore, future studies can meaningfully pursue causes of mean differences across age and between genders.

The Impact

Sentiment analysis is a rapidly growing field of research due to the explosive growth in digital information. In the modern world of artificial intelligence, sentiment analysis is one of the essential tools to extract emotion information from massive data. Sentiment analysis is applied to a variety of user data from customer reviews to social network posts. To the best of our knowledge, there is less work on sentiment analysis based on the categorization of users by demographics. Demographics play an important role in deciding the marketing strategies for different products. In this study, we explore the impact of age and gender in sentiment analysis, as this can help e-commerce retailers to market their products based on specific demographics. The dataset is created by collecting reviews on books from Facebook users by asking them to answer a questionnaire containing questions about their preferences in books, along with their age groups and gender information. Next, the paper analyzes the segmented data for sentiments based on each age group and gender. Finally, sentiment analysis is done using different Machine Learning (ML) approaches including maximum entropy, support vector machine, convolutional neural network, and long short term memory to study the impact of age and gender on user reviews. Experiments have been conducted to identify new insights into the effect of age and gender for sentiment analysis.

This study evaluated the social and ecological factors that affect entomophagy in Ghana with a view to instigate the initiation of programmes for the use of insects for human and poultry nutrition in Africa. Two thousand questionnaires were administered to randomly selected respondents in all the ten regions of Ghana. With regards to social factors, entomophagy was found to be influenced by age, gender, education and occupation. Entomophagy is practiced across all age groups and gender in Ghana. Proportionally, 90, 78 and 74% of the aged (60+), middle aged (31-50) and the youth (18-30), respectively, were observed to consume various insect species. Ecologically, entomophagy was more pronounced in rural than urban areas. Over 87% of respondents who consume edible insects acquire them through harvesting/trapping. Four insect species were identified as feed for animals. The majority (81.6%) of the respondents consume insects as a source of protein, 9.6% for cultural reasons, 5.6% for medicinal values and 3.0 and 0.2%, respectively, for recreational and religious reasons. Gender has the least influence on entomophagy. Considering the economic, ecological and nutritional importance of edible insects in traditional Ghanaian foods, attention should be given to sustainable environmental harvesting practices.

Abstract This study investigated the performance of children from the Brazilian Northeast region, from 7 to 10 years in phonemic and semantic verbal fluency tasks. The participants were 102 subjects (62 girls and 40 boys) who performed three phonemic and three semantic fluency tasks. The results were submitted to correlational and variance analysis to investigate the influence of the variables age and gender on the subjects performance. There was no effect of gender on the results. Significant contrasts between age groups were found, and better performance was observed on phonemic tasks. Also, the performance in this task changed along development, in contrast to what happened with the semantic fluency. The findings seem to be in accordance to neurodevelopmental aspects, taken into account that explicit memory systems show more precocious maturational course, with earlier consolidation, in comparison to the executive functions and frontal lobes, which go on developing until adult ages.

The Stability

The purposes of this study were to determine the stability of estimations of success in masculine, feminine, and gender-neutral motor tasks with subjects of three age groups, and to compare expectancies for success of boys and girls at each of the ages. A total of 90 subjects took part in the study, including 15 males and 15 females randomly selected from the three age groups (grades 1 & 2; grades 6 & 7; and adults). Three activities (football, ballet, and swimming) had been sex-typed in a previous study as masculine, feminine, and neutral, respectively. Subjects were asked to indicate how they would expect to perform on three occasions in all three tasks. Results indicated that all age groups can provide reliable expectations for their success in motor skill acquisition, although the younger children's estimates are slightly less reliable, especially on the first trial. Sex-typing of activities was found to definitely affect the performance estimations in all three age groups. Males' expectancies were higher on the male task and females' expectancies were higher on the female task. The younger children's overall estimates of success were higher than those of the older groups.
