In this study we investigated the relationship between tambaqui fish (Colossoma macropomumi Cuvier 1818) and parasites in two fish farms (L204S and L180N) in the state of Rondônia, Brazil, during a 1-year period. The objective of the study was to describe the relationships between parasites, hosts and the environment. From the 80 fish specimens collected, 100% were parasitized by at least one parasite species. Seven ectoparasites species were recorded, six of the class Monogenea: Anacanthorus spathulatusi, Mymarothecium spp. (Mymarothecium sp. 1, Mymarothecium sp. 2 and M. viatorum), Notozothecium sp. and Linguadactyloides brinkimanni, classified as dominants, and the copepod Perulernaea gamitanae, classified as subordinate. Despite their high prevalence, the parasites were not abundant. A. spathulatus presented positive and significant correlations between the abundance of parasitism and the standard length of the hosts in the two fish farms; Mymarothecium spp. showed significant correlations, negative in L180N, and positive in L204S; significant positive correlations were observed for Notozothecium sp. in L204S, and for L.brinkimanni in L180N. Young monogeneans were found; these parasites presented a negative correlation in L180N and a significant negative correlation in L204S. The results of the correlation between the relative condition factor (Kn) and the abundance of parasites were not significant for the recorded parasite species. Regarding the hepatosomatic relation (HSR) of fish and the abundance of parasites, Anacanthorus spathulatusi showed a significant negative correlation with the HSR in L180N, and a positive correlation in L204S. Mymarothecium spp. and Notozothecium sp. presented significant positive correlations in L204S. Considering the correlation of the fish splenosomatic relation (SSR) and the abundance of parasites, L. brinkimanni presented significant correlations, positive in L180N and negative in L204S. Despite 100% prevalence, the high water quality contributes to infracommunities with low parasite abundance and good levels of Kn, HSR and SSR, allowing good tambaqui development.

The Relationship

The relationship between follicle number per unit area and wool production per unit area was examined in strong-wool (South Australian) and medium-wool (Peppin) Merino sheep. In four groups of strong-wool sheep (varying in number from 103 to 197 sheep) non-significant positive correlations were observed between follicle number per unit area and the amount of clean wool delineated by a 1 in. calliper. In two groups of strong-wool sheep (178 ewes and 169 rams) and one group of medium-wool sheep (184 ewes) the relationship between follicle number and unit area wool production was inferred from the association between number and fibre weight. There was a highly significant negative correlation (r = – 0.45 approx.) between number and fibre weight in each group. Further, a highly significant difference was observed between sire groups in mean fibre weight after adjustment for differences in follicle number. It was concluded that there was a small positive correlation between follicle number and wool production. This association was so small as to be of dubious biological significance. There were strong indications of a negative genetic correlation between follicle number and wool production, although this did not attain statistical significance.

A geographic information system (GIS) was used to create an interface to evaluate the relationship between the amount of greenness and the crime level within the city of Austin, Texas. Results indicated a statistically significant negative correlation between the incidence of crime committed in the Austin greater metropolitan area for the year 1995 and the amount of vegetation within the area in which those crimes occurred. Areas with less than the average mean greenness level in Austin had an increased amount of crime. Results indicated no statistically significant relationship between the level of greenness of the crime sites and the severity of the crimes committed, and income level appeared to have no statistically significant effect on the severity of crimes committed.

Insomnia Severity

Abstract Introduction Bedtime Procrastination (BP) is defined as the behavior of going to bed later than intended, despite the absence of external factors. Bedtime procrastination is also prevalent among insomnia patients, and is associated with various sleep problems. Recent studies suggest emotional regulation as a mechanism of the procrastination behavior that is the conceptual foundation of bedtime procrastination. Emotional regulation difficulties are also associated with insomnia, but there is still a lack of research on the relationship between insomnia, emotional regulation strategies and bedtime procrastination. Thus, the study assumed that severity of insomnia would affect bedtime procrastination, and examined the moderating effect of the emotional regulation strategies in this relationship. Methods This study was conducted in 376 adults (mean age 23.73 ±2.14 years, 84.6% females). Participants were asked to answer Bedtime procrastination scale (BPS), an emotional regulation strategy checklist, and the Insomnia severity scale (ISI). Results As a result, a significant positive correlation was found between insomnia severity and bedtime procrastination (r=.286, p<.01), and avoidant/distractive regulation style (r=.101, p<.05). active regulation style (r=-.172, p<.01) and support seeking regulation style (r=-.102, p<.01) showed a significant negative correlation with the severity of insomnia. Bedtime procrastination behavior showed significant negative correlation only with active regulation style (r=-.151, p<.01). Support seeking regulation style moderated the relationship between insomnia and bedtime procrastination behavior (B=.0165, 95%, CI=.0014, .0316). The interaction effect between insomnia and support seeking regulation style was also significant (∆R^2=.0112, p<.05), indicating that the effect of insomnia on bedtime procrastination depends on the level of use of the support seeking regulation style. Conclusion These findings suggest that the level of support seeking regulation style is meaningful in terms of how insomnia affects bedtime procrastination.

The Relationship

We examined the relationships among psychological empowerment, emotional labor strategies, and job burnout of frontline hotel employees with reference to conservation of resources theory and the job demands–resources model. A sample of 414 employees from a Chinese chain hotel was recruited to take part in this study. There was a significant negative correlation between psychological empowerment and job burnout for these frontline hotel employees. Furthermore, the emotional labor strategies of deep acting and automatic regulation played partial mediating roles in the relationship between psychological empowerment and job burnout, which has implications for the development of intervention mechanisms and work practices for addressing burnout.

AbstractThis study aimed to noninvasively assess the relationship between the labial gingival thickness (GT) and the underlying bone thickness (BT) of maxillary anterior teeth by two digital techniques. A total of 30 periodontally healthy participants with 172 maxillary anterior teeth were enrolled. GT and BT were measured at 2, 4 and 6 mm apical to the cemento-enamel junction (CEJ) by two digital techniques: M1—cone-beam computed tomography (CBCT) and M2—digital intraoral scanning (DIS) combined with CBCT. The Pearson's correlation coefficient was calculated to determine the correlation between GT and BT. A significant negative correlation was identified between GT and BT at 2 mm apical to the CEJ for central incisors (CI), lateral incisors (LI), and canines (CA) both by M1 and M2, while a weak negative correlation at 4 mm apical to the CEJ was observed by M1 for CA. No significant correlation was found at other sites by both M1 and M2. The labial BT was < 1 mm in most cases (85% of CI; 97% of LI; and 90% of CA). Within the limitation of this study, it was concluded that GT and BT seemed to be negatively correlated at 2 mm apical to the CEJ. Therefore, caution is warranted when implant restoration at the esthetic area of the anterior teeth.

We evaluated variables important to understanding dissociation ( N = 379 undergraduates). We investigated: (a) the correlations among dissociation and impulsivity, alexithymia, mindfulness, negative affect, neuroticism, sleep disturbances, and emotion dysregulation; (b) unique variance of these variables in statistically predicting dissociation scores; and (c) the statistical mediational role of emotion dysregulation and sleep in explaining dissociation. We found significant positive correlations between dissociation and emotion dysregulation, sleep, alexithymia, negative affect, impulsivity, and neuroticism as well as a significant negative correlation between mindfulness and dissociation, consistent with Lynn et al . Sleep, impulsivity, emotion dysregulation, and negative affect uniquely related to and explained significant variance in dissociation, in order from most to least variance accounted for. Sleep partially mediated the relation between emotion dysregulation and dissociation and the relation between impulsivity and dissociation. Emotion dysregulation partially mediated the relation between sleep and dissociation and the relation between impulsivity and dissociation. Additional findings provided support for bidirectional relations between sleep experiences and dissociation and emotion dysregulation and dissociation.

Background and objective: Suicide still constitutes to be a critical and risky issue requiring preventive strategies. There is evidence to suggest that spirituality is vital to the process of discovering meaning in life and plays an important role in dealing with suicidal desire. The aim of this study was to investigate the relationship between spirituality and suicidal ideations among patients with major depressive disorder.Methods: Design and participants: A descriptive correlational design was utilized in the current study. A purposive sample of 181 patients with major depressive disorder was recruited. Setting: The study was conducted at inpatient psychiatric department of Tanta University and Neurology, Psychiatry, and Neuro-Surgery Center. Both hospitals are under the supervision and direction of the ministry of higher education. Tools: Four tools were used to collect data; socio-demographic and clinical characteristics structured interview schedule, Beck Depression Inventory, Daily Spiritual Experience Scale, and Scale for Suicide Ideation.Results: The current study indicated a statistical significant negative correlation between depression and spirituality. Also, a statistical significant negative correlation was found between spirituality and one subscale of suicide which is active suicide desire subscale. On the other side, there was a statistical significant positive correlation between depression and total score of suicide.Conclusions: Higher levels of spirituality may help buffer risk of active suicide desire and promote protective effect against depression. Recommendation: interventions that aim at increasing spiritual involvement and practice may be beneficial in reducing depressive symptoms and suicide desire.
