AbstractA previous study of maternal behavior in the rabbit dealing with the improvement in nest quality in successive parturitions is here extended to four other aspects of maternal behavior. No significant differences were found for scores on interest in young or pre-parturient aggression either among the four races investigated or over a number of litters. Race differences significant at the .05 level were obtained for post-parturient aggression scores involving two and four litters. A linear increase significant at the .01 level was revealed in the same measure for one race when four litters were considered. Significant racial differences were also found with respect to time of nest building. A second set of analyses dealt with the relation of other variables to the quality of nest construction. The only measure found to have a distinct positive relation to nest quality was the percentage of liveborn young suckled on the first day of life. An ambiguous, but weakly positive relationship was found between nest quality and time of nest building relative to parturition. A weak relationship was found between time of nest construction and the percent of liveborn young suckled the first day. These findings suggest the possibility of some factor or factors acting in common upon the nesting and suckling activities in maternal behavior.

Body Hair

A method is presented for determining the degree of hair loosening in the rabbit by weighing the amount of hair obtained through a standardized combing technique. The results indicate that significant hair loosening occurs during gestation in the rabbit. The time of hair loosening may vary from the 5th day prepartum to the day of parturition and in one instance the phenomenon failed to appear. The response of hair loosening is believed to be a component of the nest building-maternal behavior complex in the rabbit. The loosened body hair is used in nest construction.

Nest Quality

The physiological response to stressors has great importance, and its variance has an adaptive role in the survival of individuals. This study describes the effects of stress-axis activation on maternal behavior during the birthing process (parturition) in captive rabbits (Oryctolagus cuniculus). In this species, chances of survival are strongly influenced by nest quality. Thus, maternal care is initiated with nest preparation in late pregnancy, which itself is subject to strict and complex hormonal regulation. Among these hormones, progesterone is one of the most dominant in the process of nest construction. We have demonstrated that its level is altered by the level of cortisol elevation in the animal in question, potentially having an influence on the preparation of the nest for the newborn kittens. We found that does that had a constant and un-elevated level of cortisol metabolite while delivering their litters performed better than those individuals that showed an increased corticoid response around parturition. The latter group exhibited a perceptible delay in the building of their nests, and in addition, further losses were also experienced in their already smaller litters. As the quality of the nest itself proved to be was in no way inferior to those of the other group, this higher kitten-mortality rate may be attributed to impaired maternal behavior. Individual variances in cortisol levels may also result in subtle changes in hormonal regulation, potentially affecting the expression of maternal behavior. We have concluded that the higher level of cortisol detected in more-sensitive does effectively disrupts the natural hormonal regulation involved in their nest-building processes.

AbstractThe records of a number of female rabbits of races III, IIIc, X, and AcEp which had produced at least four litters were analyzed for correlations between scattering and cannibalism and five other measures of maternal behavior. These rabbits were classed as low newborn mortality mothers and the maternal behavior scores for their first successful litter were compared with the behavioral scores of high newborn mortality mothers (60 per cent mortality of complete litters) for their first successful litter. Only race IIIc showed any significant amount of scattering and cannibalism. In this race, correlational analyses of scattering and cannibalism against the five other measures of maternal behavior found that both were significantly related to nest quality and had weaker, though positive, correlations with time of nest building. Race IIIc does were only moderately consistent in their scattering or cannibalizing behavior over four litters and these variables were correlated .404. No differences were found between high and low newborn mortality mothers except for race AcEp, where the low mortality mothers were found to have significantly more interest in their young and to be better nurse-mothers than the high newborn mortality does. The findings from this study and a previous one (DENENBERG, et al., 1958) indicate that better nest quality, earlier time of nest building, greater percentage of live born young suckled on the first day, lack of scattering, and lack of cannibalism are inter-correlated. It was concluded that these characteristics can be classified as a "maternal care" complex which appears to be independent of a second group involving interest in young and aggressive protection.

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

The assent procedure reflects an effort to enable the minor to understand, to the degree they are capable of, what their participation in the decision making process would involve. Aims: To evaluate the minors’ ability to understand the information provided to them when obtaining assent and to evaluate the opinion of the parents regarding the importance of asking the child’s assent. Methods: The sample included a total of 52 minors aged between 10 and 17 years who underwent exercise echocardiogram. The Quality of Informed Consent is divided into two parts: Part A was used to measure objective understanding and part B to measure subjective understanding. Results: The results show that the minors have a high capacity to understand the information given to them when asking for assent. A positive relationship was found between the two parts of the questionnaire. No statistically significant relationship was found between age and sex and part A and part B or between both age groups (<14 years old and ≥14 years old) and the measure. In the case of the parents, 96.6% of parents consider assent as an advantage for the child’s acceptance of health care. The opinion of the parents is not related to the age, sex or level of schooling. Conclusion: Minors showed a substantial level of understanding regarding the information provided to them. The parents considered the implementation of assent fundamental to the child’s acceptance of health care.

Abstract Objective To summarize the current literature on disparities in the treatment of chronic pain. Methods We focused on studies conducted in the United States and published from 2000 and onward. Studies of cross-sectional, longitudinal, and interventional designs were included. Results A review of the current literature revealed that an adverse association between non-White race and treatment of chronic pain is well supported. Studies have also shown that racial differences exist in the long-term monitoring for opioid misuse among patients suffering from chronic pain. In addition, a patient’s sociodemographic profile appears to influence the relationship between chronic pain and quality of life. Results from interventional studies were mixed. Conclusions Disparities exist within the treatment of chronic pain. Currently, it is unclear how to best combat these disparities. Further work is needed to understand why disparities exist and to identify points in patients’ treatment when they are most vulnerable to unequal care. Such work will help guide the development and implementation of effective interventions.

Abstract Communication and interactions are an integral part of care in long-term care settings. Resident variables, such as race and gender, shape communication and interaction between staff and residents. The Quality of Interactions Schedule (QuIS) was developed to measure the quality of verbal and nonverbal interactions among nursing staff and older adults initially for those in acute care and later used as well in a variety of long term care settings. A quantified measurement of the quality of interactions between residents and staff was created to quantify the QuIS. The purpose of this study was to describe the gender and racial differences in scored quality of interactions. Data for the present study was based on baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) implementation study. A total of 535 residents from 55 settings were included in the analyses. An analysis of covariance was conducted to determine a difference in QuIS scores between males and females while controlling for age. The second model tested for differences in QuIS scores between blacks and whites while controlling for age and gender. There was not a statistically significant difference in QuIS scores between male and female residents. There was a significant difference in QuIS scores between those who were black versus white, such that those who were black received more positive interactions from staff than those who were white. Future work should focus on a deeper examination of resident factors and staff factors that may influence these interactions.

Happiness is a subjective indicator of overall living conditions and quality of life. Recently, community- and national-level investigations connecting happiness and community satisfaction were conducted. This study investigated the effects of community satisfaction on happiness in Nepal. A factor analysis was employed to examine 24 items that are used to measure community satisfaction, and a multiple regression analysis was conducted to investigate the effects of these factors on happiness. In semi-urban areas, sanitation showed a positive relationship with happiness. In rural areas, edu-medical services were negatively related to happiness, while agriculture was positively related. Gender and perceived health were closely associated with happiness in rural areas. Both happiness and satisfaction are subjective concepts, and are perceived differently depending on the socio-physical environment and personal needs. Sanitation, agriculture (food) and edu-medical services were critical factors that affected happiness; however, the results of this study cannot be generalized to high-income countries.
