Significant Negative Relationship

The nonlinearity and arousal hypothesis predicts that highly aroused mammals will produce nonlinear, noisy vocalizations. We tested this prediction by measuring faecal glucocorticoid metabolites (GCMs) in adult yellow-bellied marmots ( Marmota flaviventris ), and asking if variation in GCMs was positively correlated with Wiener entropy—a measure of noise. Contrary to our prediction, we found a significant negative relationship: marmots with more faecal GCMs produced calls with less noise than those with lower levels of GCMs. A previous study suggested that glucocorticoids modulate the probability that a marmot will emit a call. This study suggests that, like some other species, calls emitted from highly aroused individuals are less noisy. Glucocorticoids thus play an important, yet underappreciated role, in alarm call production.

The Impact

The main objective of this study is to investigate the impact of poverty, globalization, and environmental degradation on economic growth in the selected SAARC countries. This study is employed panel Autoregressive Distributive Lag (ARDL) technique for empirical analysis using selected SAARC regions including India, Pakistan, Bangladesh, Nepal and Sri Lanka over the period of 1980 to 2018. Globalization impacts economic growth positively and significantly.  In addition to this the significant negative relationship is found between population and economic growth. The results show that poverty is positively related with environmental degradation. Furthermore, the results indicate that globalization is positively and significantly associated with environmental degradation in the SAARC region. Finally, the results show that urbanization is positive and significantly associated with environmental degradation, which could be the serious concerns for the policy makers to control.

Practical Implications

The 2 types of exchange relationship perceptions—social exchange relationship perceptions (SERPs) and economic exchange relationship perceptions (EERPs)—constitute the primary concept for understanding individual behavior in the workplace. Using a sample of 581 employees from Mainland China, I explored the effects of SERPs and EERPs on employee extrarole behavior (ERB), as well as the moderating effect of organization-based self-esteem (OBSE) on the relationships between SERPs and ERB, and between EERPs and ERB. The results revealed a significant positive relationship between SERPs and ERB, a significant negative relationship between EERPs and ERB, and a significant moderating effect for OBSE. Theoretical and practical implications of these findings are discussed.

It is widely believed that the financial system is dependent on the banking industry, and its strength and development are vital for economic prosperity. This paper tried to show the financial performance of Iranian banks listed on the Tehran Stock Exchange (TSE) during 2013–2019, as the research population. The statistical population included 18 banks listed on the TSE from 2013 to 2019, which were sampled using a screening method. The results indicated a significant relationship between explanatory variables of capital ratio and the financial performance of banks in all models. However, a significant negative relationship was found between the inflation rate and the financial performance of banks in all models. Furthermore, it seems that banks with high asset strength are more profitable than the others. Regulators should guarantee that banks remain highly capitalized for a viable banking sector in Iran.

AbstractCombining reading with auditory input has been shown to be an effective way of supporting reading fluency and reading comprehension in a second language. Previous research has also shown that reading comprehension can be further supported by pictorial information. However, the studies conducted so far have mainly included adults or adolescents and have been based on post-reading tests that, although informative, do not contribute to our understanding of how learners’ processing of the several sources of input in multimodal texts changes with the presence of auditory input and the effect that potential differences could have on comprehension. The present study used eye-tracking to examine how young learners process the pictorial and textual information in a graded reader under reading only and reading-while-listening conditions. Results showed that readers spent more time processing the text in the reading only condition, while more time was spent processing the images in the reading-while-listening mode. Nevertheless, comprehension scores were similar for the readers in the two conditions. Additionally, our results suggested a significant (negative) relationship between the amount of time learners spent processing the text and comprehension scores in both modes.

Using Data

The article examines the link between workplace disability (WD) and workplace job satisfaction (JS) using data from WERS2011. Controlling for a rich set of workplace characteristics including organisational culture, the study finds a significant negative relationship between JS and the share of disabled respondents within workplaces. Notably, Seemingly Unrelated Regression (SUR)-based analysis distinguishing between disabled and non-disabled respondents reveals that the negative relationship found is specific to non-disabled respondents. Moreover, disability equality policies are found to be significantly positively related with disabled respondents’ JS while they are negatively related with the JS of their non-disabled counterparts. The article ponders if there is a co-worker aspect to the WD–JS link and whether HR policies may need to take heed of co-worker dynamics in this respect.

Abstract Objective This study aimed to understand the implications that smartphones have for prospective memory (PM) performance. We examined normal adults’ performance on an event-based PM task embedded in an online survey, and its relationship with the PM strategies used prior to the PM cue. Method Participants included 349 individuals aged >18— (M = 38.31; SD = 11.15); 62% male; non-Hispanic (83.38%); with education = HS diploma or less (8.31%), some college (12.61%), and college degree (79.08%)—recruited through Amazon Mechanical Turk. Participants completed the survey on their smartphones. The PM task required participants to respond “N/A” to a question presented later in the survey. Follow-up questions were asked about the use of external reminders, internal monitoring, recollections, and level of importance participants attributed to the PM task. Results One third of participants were successful on the PM task. Of those who had PM success, 11.50% used external reminders, 53.10% used internal monitoring strategies, 62.83% had recollections, and 95.56% considered the task at least somewhat important to remember. Logistic regression revealed that non-Hispanic ethnicity, ≤ high school education, and high perceived importance predicted PM success (Table 1). Interestingly, 40% of individuals with PM failure used external reminders, showing a significant negative relationship with PM success. Conclusions We found that external reminders, internal monitoring, and recollections may make PM success less likely during smartphone use—strategies which were associated with PM success in previous research. Only perceived importance predicted PM success, akin to previous findings. Implications reveal that smartphones may change the demands of PM tasks.

Existing literature has explored the role of mindfulness and mind-wandering on creative processes. However, it has overlooked the diversity in the creative domains as well as the experience of the artist while accounting for their relationship. In the present study, mindfulness and mind wandering- deliberate and spontaneous were explored among performing artists, i.e. musicians, theatre artists, and dancers. The study also looked at the artists’ experience in their field. After an initial screening using a creativity tool, 66 performing artists were recruited, following which two self-report indices that assessed mind wandering and mindfulness were administered. The data collected was subjected to quantitative data analysis in SPSS. A Oneway ANOVA showed significant effect of the creative domain on mindfulness for the three groups, with a significant difference between musicians and dancers. Among the musicians, a significant negative relationship between mind wandering spontaneous and years of experience was seen. Among the dancers, there was a significant positive association between mind wandering spontaneous, mind wandering deliberate and years of experience. The current study highlighted the need to approach the study of creativity using a contextual perspective. Keywords: Creativity, Dance, Music, Theatre.

This study observes a particular group of students learning medical terms (MT) implicitly through studying medical subjects. That is, based on the policy followed in the context of the study, students shall not receive any deliberate terms instruction. This paper investigates their experiences and attitudes towards acquiring MT in such a situation. Students’ acquisition and proficiency, hypothesizing a positive relationship between the two constructs, are self-assessed through pre- and post-test surveys. The surveys included 114 and 95 students in each phase, respectively. Prior to the surveys, focus group discussions were conducted, according to which the questionnaire was developed. A statistical correlational Pearson test was done to examine the relationship between students’ proficiency and incidental terms acquisition. The results indicated a significant negative relationship between the two constructs tested. The study also tested the effect of time on increasing acquisition through conducting a paired independent t-test between the two sets of data. The results found that a more extended period was significant to incidental acquisition. Overall, through comparing the means, modes, and medians in the two phases (pre- and post-test), the findings reveal an increase in the students’ terms acquisition volume. However, students seem not to favour the approach and still advocate explicit instruction for technical terms.

The size of an animal’s home range is strongly influenced by the resources available within it. In productive, resource-rich habitats sufficient resources are obtainable within a smaller area, and for many species, home ranges are smaller in resource-rich habitats than in habitats with lower resource abundance. Location data on 14 male and 27 female echidnas (Tachyglossus aculeatus) fitted with tracking transmitters, in the southern midlands of Tasmania, were used to test the influence of habitat type on home-range size. We hypothesised that as woodland should offer more shelter, food resources and refuges than pasture, echidnas living in woodland would have smaller home ranges than those living in pasture areas. We found significant differences between the sexes. Male echidnas had a significantly larger mean home range than females and a quite different relationship between home-range size and habitat type from females. There was no relationship between the proportion of woodland within male home ranges and home-range size whereas female echidnas had a highly significant negative relationship. This suggests that home-range size of female echidnas is highly influenced by the amount of woodland within it, but the home-range size of male echidnas is controlled by factors other than habitat. This pattern is consistent with the spatial ecology of many other solitary species with a promiscuous mating system. The home ranges of females are scaled to encompass all necessary resources for successfully raising their young within a minimal area, whilst the large home ranges of males are scaled to maximise access to females.

The aim of the study was to analyze the influence of depression on the protein-energy reserves and the BodyMass Index in ederly. A total of 65 older adults were evaluated; to identify the level of depression, the Yesavage Geriatric Depression Scale was used, the protein-energy reserves were evaluated from the arm circumference and the Body Mass Index. The elderly with higher levels of depression had lower arm circumference than those who did not show depression according to the scale (p = 0.002 and p = 0.009, men and women respectively), a similar situation occurs with the BMI (p = 0.050 and p = 0.019). There is also a significant negative relationship between the Geriatric Depression Scale with the arm circumference and the BMI in women (r = -0.520, p = 0.002 and r = -0.439, p = 0.009 respectively). In men, this negative relationship is observed only between the Geriatric Depression Scale and the arm circumference (r = -0.479, p = 0.007). Older adults with a higher level of depression have lower arm circumference and lower BMI than those without depression. In both sexes, there is a significant negative relationship between the Geriatric Depression Scale score and the arm circumference. In females, an inversely proportional relationship between the scale and the Body Mass Index is evidenced.
