Purpose The purpose of this paper is to look at the insights of the value of the society influenced by sharing economy (SE). The study focused on both the benefits and flaws of SE by using the case of renowned SE platform “Uber” to come up with a holistic perspective of these effects from both the facets. Design/methodology/approach This study collects data from demand and supply side using interview and questionnaire. Then the grounded theory is adopted to analyze interview data and come up with six major research constructs. Further, quantitative analyses methods are applied on questionnaires to test “whether sharing economy creates social value” and to approximately estimate the extent to which sharing is economy influencing social value. Findings Findings suggested that, when only drivers were inquired about positive and negative effects of SE, positive effects were dominant. Also, when passengers were asked their opinion was also in favor of positive effects. From quantitative data analysis, the major factor significantly influencing the sustainability of the SE was “efficiency.” “Security issues and regulatory issues” were the prime negative factors, though again there was not enough statistical evidence to validate their significance. The authors hereby conclude that the positive contribution of SE is more, and it is increasing the values of the society. And the positive effects were twice significant than the negative effects. Originality/value Theoretically, the study contributes to finding both the helpful and harmful effects of SE on the values of the society. Practically, it suggests that governments should allow growth of SE under proper regulations. And car-sharing companies should focus on solving the security issues and regulatory issues.

In this study, it is aimed to analyze the positive effects of pets on the market economy and people. The COVID-19 pandemic started with the virus outbreak that emerged in Wuhan City, the capital of Hubei Province of China, on December 1, 2019 [1], and the first case in our country was announced by the Ministry of Health on March 11, 2020. With the rapid spread of the epidemic in the world, closures in countries, travel restrictions, working from home and the introduction of the online education system, the rate of spending more time with pets, known as people's loyal friends, and the rate of adopting new animals have begun to increase. In this process, it has been seen that people are more interested in their animals and they are more sensitive in meeting their needs. It has been observed that they do not hesitate to allocate a significant part of their budgets in many subjects such as animal nutrition and veterinary care services, consumption expenditures such as pad shop products and purchasing new animals have increased, and this market has been dynamic. It is known that having a pet is good for blood pressure, greatly reduces the feeling of loneliness and depression in people, and always keeps their hopes warm. It can be said that taking care of furry friends after a long day helps people feel more optimistic and spending time with their pets helps them cope with stress, helps animals increase social relationships, and develops empathy, social skills, mutual love and sense of responsibility in children. It can be said that spending time with their pets is good for people's mood, and they even prefer their animals over other people in quarantine, and they gain social status. The trend of online shopping for pets also seems to become permanent. Pets are now more important than ever in our lives. The pandemic may ease in the near future, but the closeness of our pets will be permanent. It is seen that the tendency towards the adoption of pets and meeting their needs such as care and nutrition is increasing day by day. While various needs come to the fore in this trend, it is important to determine the economic role of consumption of these needs and their relationship with the reasons.

Females of an inbred al c: se ss: eyR mutant strain were crossed with males from a "wild" strain that had been inbred (brother × sister) for more than 60 generations. The F1 males were mated with mutant strain females. The backcross offspring would be expected to appear in eight genotypes with equal frequencies were there no differences in viability. The marker genes permitted the scoring of each fly as to whether it was heterozygous or homozygous for each of the mutant autosomes.The genes used as markers probably had a distinctly negative effect upon both viability and rate of development, but the second pair of autosomes in combination with the other mutant autosomes increased viability, when homozygous, to a greater extent than did a heterozygous mutant-wild type pair. Apparently the possible negative effects of the markers al and c were more than offset by other genes on this autosome which had positive effects. The negative effects of the homozygous mutant third and fourth chromosomes were severe when in combination.The interactions of the positive second chromosome and the negative third and fourth chromosomes in the eight genotypes were of some geometric order. It was found that the addition of a "positive" or "negative" autosome to any genotype caused a change in viability in the direction of the added autosome, but the amount of change is at present unpredictable and depends upon the particular combination to which the autosome was added.The relation between the different autosomes and the rate of development was quite different from the relation between autosomes and viability. The second chromosome (marked by al c), which gave the only positive contribution to viability, retarded development more than either the third (se ss) or the fourth (eyR). The effects of the three autosomes on rate of development were not strictly additive.It is concluded that there is interaction of the genes for quantitative characters and this interaction is geometric in nature. The significance of the results in their relation to some theories of the inheritance of quantitative characters is discussed.

Secondary Crashes

A consecutive crash series is composed by a primary crash and one or more subsequent secondary crashes that occur immediately within a certain distance. The crash mechanism of a consecutive crash series is distinctive, as it is different from common primary and secondary crashes mainly caused by queuing effects and chain-reaction crashes that involve multiple collisions in one crash. It commonly affects a large area of road space and possibly causes congestions and significant delays in evacuation and clearance. This study identified the influential factors determining the severity of primary and secondary crashes in a consecutive crash series. Basic, random-effects, random-parameters, and two-level binary logistic regression models were established based on crash data collected on the freeway network of Guizhou Province, China in 2018, of which 349 were identified as consecutive crashes. According to the model performance metrics, the two-level logistic model outperformed the other three models. On the crash level, double-vehicle primary crash had a negative association with the severity of secondary consecutive crashes, and the involvement of trucks in the secondary consecutive crash had a positive contribution to its crash severity. On a road segment level, speed limit, traffic volume, tunnel, and extreme weather conditions such as rainy and cloudy days had positive effects on consecutive crash severity, while the number of lanes was negatively associated with consecutive crash severity. Policy suggestions are made to alleviate the severity of consecutive crashes by reminding the drivers with real-time potential hazards of severe consecutive crashes and providing educative programs to specific groups of drivers.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Purpose Among the best strategies to address inadequate speech monitoring skills and other parameters of communication in people with cluttering (PWC) is the relatively new but very promising auditory–visual feedback (AVF) training ( van Zaalen & Reichel, 2015 ). This study examines the effects of AVF training on articulatory accuracy, pause duration, frequency, and type of disfluencies of PWC, as well as on the emotional and cognitive aspects that may be present in clients with this communication disorder ( Reichel, 2010 ; van Zaalen & Reichel, 2015 ). Methods In this study, 12 male adolescents and adults—6 with phonological and 6 with syntactic cluttering—were provided with weekly AVF training for 12 weeks, with a 3-month follow-up. Data was gathered on baseline (T0), Week 6 (T1), Week 12 (T2), and after follow-up (T3). Spontaneous speech was recorded and analyzed by using digital audio-recording and speech analysis software known as Praat ( Boersma & Weenink, 2017 ). Results The results of this study indicated that PWC demonstrated significant improvements in articulatory rate measurements and in pause duration following the AVF training. In addition, the PWC in the study reported positive effects on their ability to retell a story and to speak in more complete sentences. PWC felt better about formulating their ideas and were more satisfied with their interactions with people around them. Conclusions The AVF training was found to be an effective approach for improving monitoring skills of PWC with both quantitative and qualitative benefits in the behavioral, cognitive, emotional, and social domains of communication.

To investigate the effects of leisure activities on cognitive performance of healthy older subjects, an innovative intervention program was developed. Frequent participation in cognitively stimulating activities (i.e., reading, playing chess, or playing music) is associated with reduced risk of dementia. AKTIVA (active cognitive stimulation – prevention in the elderly) is an intervention program designed to enhance cognitive stimulation in everyday life by increasing cognitive stimulating leisure activities. The present study determines the effects of AKTIVA on cognitive function, mood and attitude toward aging in a sample of older participants from the general population. Several measurement instruments were used including the Alzheimer’s Disease Assessment Scale (ADAS-Cog), the Trail-Making Test (TMT), and the Memory Complaint Questionnaire (MAC-Q). Initially, the sample consisted of 307 older persons (170 female, 72 ± 7 years). The intervention was evaluated with a randomized, controlled pre-post follow-up design. Participants were randomly assigned to one of three conditions: AKTIVA intervention (n = 126), AKTIVA intervention plus nutrition and exercise counseling (n = 84), no-intervention control group (n = 97). The AKTIVA intervention consisted of 8 weekly sessions and two booster sessions after a break of 4 months. Participation in the group program resulted in positive effects on cognitive function and attitude toward aging for subassembly groups. Older persons (≥ 75 years) showed enhanced speed of information processing (by TMT Version A) (F = 4.17*, p < .05); younger participants (< 75 years) showed an improvement in subjective memory decline (by MAC-Q) (F = 2.55*, p < .05). Additionally, AKTIVA enhanced the frequency of activities for leisure activities for subassembly groups. The results of this study suggest that the AKTIVA program can be used to increase cognitively stimulating leisure activities in the elderly. Further research is necessary to identify the long-term effects of this intervention particularly with respect to the prevention of dementia.

Role Demands

Men’s professional work roles require different attributes according to the gender-typicality of their occupation (female- versus male-dominated). We predicted that levels of men’s strain and job satisfaction would be predicted by levels of self-ascribed instrumental and expressive attributes. Therefore, we tested for positive effects of instrumentality for men in general, and instrumentality in interaction with expressiveness for men in female-dominated occupations in particular. Data were based on a survey of 213 men working in female-dominated occupations and 99 men working in male-dominated occupations. We found instrumentality to be negatively related to men’s strain and positively related to their job satisfaction. We also found expressiveness of men in female-dominated occupations to be related to reduced strain when instrumentality was low. This suggests it is important for men to be able to identify highly with either instrumentality or expressiveness when regulating role demands in female-dominated occupations.
