Interpreting Parenting Plans as Contracts

When parents are divorced or separated, a parenting plan serves as a legal instrument to govern the means by which they raise their children. Most parents are able to compromise and reach an agreed-upon parenting plan without resorting to a trial or court intervention. These agreed-upon parenting plans are, in a manner of speaking, contracts that these parents must abide by. But too often parenting plans are not treated or considered in the same way we perceive ordinary contracts. They should be. This essay examines the interplay between courts reviewing agreed-upon plans, the best interest standard, and basic contract interpretation

Volunteer Growth in America: A Review of Trends Since 1974

The Corporation has produced a national report that for the first time tracks volunteering over a 30-year period. "Volunteer Growth in America: A Review of Trends Since 1974" illustrates how volunteering has rebounded to a 30-year high today -- rising by more than 32 percent over the past 16 years -- after declining between 1974 and 1989. The report found that older teenagers (ages 16-19) have more than doubled their time spent volunteering since 1989; that far from being a "Me Generation," that Baby Boomers are volunteering at sharply higher rates than did the previous generation at mid-life; and that the volunteer rate for Americans ages 65 years and over has increased 64 percent since 1974; and the proportion of Americans volunteering with an educational or youth service organization has seen a 63 percent increase just since just 1989. "Volunteer Growth in America" is based on statistics from the U.S. Census Bureau and the Bureau of Labor Statistics. The findings are encouraging while demonstrating that more engagement is needed to achieve a national goal of raising the number of volunteers from 65 million in 2005 to 75 million by 2010

The effects of feeding on heart activity in the terrestrial slug, Limax maximus : central and peripheral control

The role of the central nervous system (CNS) in the modulation of heart activity induced by feeding was investigated in the terrestrial slug, Limax maximus . Intact slugs and semi-intact preparations were used to examine the effects of food, non-nutritive bulk, digestive tract distension, and the concentration of hemolymph glucose on the control of heart activity. The heart rate of intact slugs increased following ingestion of food or nonnutritive bulk and in response to injections of glucose. The heart rate of semi-intact preparations increased in response to gradual crop inflation and to perfusion of the heart with a glucose solution for longer than 30 min. The present results indicate that the increase in heart rate observed in intact slugs following a meal is mediated in part by the CNS and in part is a direct response of the heart musculature. The CNS mediates an immediate response to proprioceptive input from stretch of the crop while the heart musculature responds directly to increased hemolymph glucose concentration following ingestion of food.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47091/1/359_2004_Article_BF00613977.pd

What is the role of the film viewer? The effects of narrative comprehension and viewing task on gaze control in film

Film is ubiquitous, but the processes that guide viewers' attention while viewing film narratives are poorly understood. In fact, many film theorists and practitioners disagree on whether the film stimulus (bottom-up) or the viewer (top-down) is more important in determining how we watch movies. Reading research has shown a strong connection between eye movements and comprehension, and scene perception studies have shown strong effects of viewing tasks on eye movements, but such idiosyncratic top-down control of gaze in film would be anathema to the universal control mainstream filmmakers typically aim for. Thus, in two experiments we tested whether the eye movements and comprehension relationship similarly held in a classic film example, the famous opening scene of Orson Welles' Touch of Evil (Welles & Zugsmith, Touch of Evil, 1958). Comprehension differences were compared with more volitionally controlled task-based effects on eye movements. To investigate the effects of comprehension on eye movements during film viewing, we manipulated viewers' comprehension by starting participants at different points in a film, and then tracked their eyes. Overall, the manipulation created large differences in comprehension, but only produced modest differences in eye movements. To amplify top-down effects on eye movements, a task manipulation was designed to prioritize peripheral scene features: a map task. This task manipulation created large differences in eye movements when compared to participants freely viewing the clip for comprehension. Thus, to allow for strong, volitional top-down control of eye movements in film, task manipulations need to make features that are important to narrative comprehension irrelevant to the viewing task. The evidence provided by this experimental case study suggests that filmmakers' belief in their ability to create systematic gaze behavior across viewers is confirmed, but that this does not indicate universally similar comprehension of the film narrative

Scanpath analysis of expertise and culture in teacher gaze in real-world classrooms

Humans are born to learn by understanding where adults look. This is likely to extend into the classroom, making teacher gaze an important topic for study. Expert teacher gaze has mainly been investigated in the laboratory, and has focused mostly on one cognitive process: teacher attentional (i.e., information-seeking) gaze. No known research has made direct cultural comparisons of teacher gaze or successfully found expert–novice differences outside Western settings. Accordingly, we conducted a real-world study of expert teacher gaze across two cultural settings, exploring communicative (i.e., information-giving) as well as attentional gaze. Forty secondary school teachers wore eye-tracking glasses, with 20 teachers (10 expert; 10 novice) from the UK and 20 teachers (10 expert; 10 novice) from Hong Kong. We used a novel eye-tracking scanpath analysis to ascertain the importance of expertise and culture, individually and as a combination. Attentional teacher scanpaths were significantly more similar within than across expertise and expertise + culture sub-groups; communicative scanpaths were significantly more similar within than across expertise and culture. Detailed analysis suggests that (1) expert teachers refer back to students constantly through focused gaze during both attentional and communicative gaze and that (2) expert teachers in Hong Kong scan students more than experts do in the UK

Differential diagnosis of suspected multiple sclerosis: a consensus approach

BACKGROUND AND OBJECTIVES: Diagnosis of multiple sclerosis (MS) requires exclusion of diseases that could better explain the clinical and paraclinical findings. A systematic process for exclusion of alternative diagnoses has not been defined. An International Panel of MS experts developed consensus perspectives on MS differential diagnosis. METHODS: Using available literature and consensus, we developed guidelines for MS differential diagnosis, focusing on exclusion of potential MS mimics, diagnosis of common initial isolated clinical syndromes, and differentiating between MS and non-MS idiopathic inflammatory demyelinating diseases. RESULTS: We present recommendations for 1) clinical and paraclinical red flags suggesting alternative diagnoses to MS; 2) more precise definition of "clinically isolated syndromes" (CIS), often the first presentations of MS or its alternatives; 3) algorithms for diagnosis of three common CISs related to MS in the optic nerves, brainstem, and spinal cord; and 4) a classification scheme and diagnosis criteria for idiopathic inflammatory demyelinating disorders of the central nervous system. CONCLUSIONS: Differential diagnosis leading to MS or alternatives is complex and a strong evidence base is lacking. Consensus-determined guidelines provide a practical path for diagnosis and will be useful for the non-MS specialist neurologist. Recommendations are made for future research to validate and support these guidelines. Guidance on the differential diagnosis process when MS is under consideration will enhance diagnostic accuracy and precision

A longitudinal study of systemic inflammation and recovery of lean body mass among malnourished HIV-infected adults starting antiretroviral therapy in Tanzania and Zambia

BACKGROUND/OBJECTIVES: The effects of inflammation on nutritional rehabilitation after starting antiretroviral therapy (ART) are not well understood. We assessed the relationship between inflammation and body composition among patients enrolled in the Nutritional Support for African Adults Starting Antiretroviral therapy (NUSTART) trial in Tanzania and Zambia from 2011 to 2013. SUBJECTS/METHODS: HIV-infected, ART-eligible adults with body mass index (BMI) of <18.5 kg/m(2) enrolled in the NUSTART trial were eligible for this study. Anthropometric and body composition data were collected at recruitment and 6 and 12 weeks post ART and C-reactive protein (CRP) was measured at recruitment and 6 weeks. The relationships between CRP and body composition were assessed using multiple regression. RESULTS: Of the 1815 trial participants, 838 (46%) had baseline and 6-week CRP measurements. Median age was 36 years, 55% were females and median CD4 count was 135 cells/μl. A one-log reduction in CRP at 6 weeks was associated with increased mid-upper arm circumference (0.45 cm; 95% CI: 0.30, 0.61), calf circumference (0.38 cm; 0.23, 0.54), waist circumference (0.98 cm; 0.59, 1.37), BMI (0.37 kg/m(2); 0.24, 0.50) and fat-free mass (0.58 kg; 0.26, 0.91), but not with fat mass (0.09 kg; -0.17, 0.34). Fat-free mass gains persisted at 12 weeks and were more closely associated with 6-week CRP values than with baseline values. CONCLUSIONS: Reduction in CRP shortly after ART initiation was associated with higher fat-free mass gains. Further studies are warranted to determine whether interventions to reduce systemic inflammation will enhance gains in fat-free mass

Risk of cardiovascular events from current, recent, and cumulative exposure to abacavir among persons living with HIV who were receiving antiretroviral therapy in the United States: a cohort study

Abstract Background There is ongoing controversy regarding abacavir use in the treatment of HIV infection and the risk of subsequent development of cardiovascular disease. It is unclear how the risk varies as exposure accumulates. Methods Using an administrative health-plan dataset, risk of cardiovascular disease events (CVDe), defined as the first episode of an acute myocardial infarction or a coronary intervention procedure, associated with abacavir exposure was assessed among HIV-infected individuals receiving antiretroviral therapy across the U.S. from October 2009 through December 2014. The data were longitudinal, and analyzed using marginal structural models. Results Over 114,470 person-years (n = 72,733) of ART exposure, 714 CVDe occurred at an incidence rate (IR) (95% CI) of 6·23 (5·80, 6·71)/1000 person-years. Individuals exposed to abacavir had a higher IR of CVDe of 9·74 (8·24, 11·52)/1000 person-years as compared to 5·75 (5·30, 6·24)/1000 person-years for those exposed to other antiretroviral agents. The hazard (HR; 95% CI) of CVDe was increased for current (1·43; 1·18, 1·73), recent (1·41; 1·16, 1·70), and cumulative [(1·18; 1·06, 1·31) per year] exposure to abacavir. The risk for cumulative exposure followed a bell-shaped dose-response curve peaking at 24-months of exposure. Risk was similarly elevated among participants free of pre-existing heart disease or history of illicit substance use at baseline. Conclusion Current, recent, and cumulative use of abacavir was associated with an increased risk of CVDe. The findings were consistent irrespective of underlying cardiovascular risk factors

The problem of constitutional legitimation: what the debate on electoral quotas tells us about the legitimacy of decision-making rules in constitutional choice

Proponents of electoral quotas have a ‘dependent interpretation’ of democracy, i.e. they have formed an opinion on which decision-making rules are fair on the basis of their prior approval of the outcomes these rules are likely to generate. The article argues that this position causes an irresolvable problem for constitutional processes that seek to legitimately enact institutional change. While constitutional revision governed by formal equality allows the introduction of electoral quotas, this avenue is normatively untenable for proponents of affirmative action if they are consistent with their claim that formal equality reproduces biases and power asymmetries at all levels of decision-making. Their critique raises a fundamental challenge to the constitutional revision rule itself as equally unfair. Without consensus on the decision-making process by which new post-constitutional rules can be legitimately enacted, procedural fairness becomes an issue impossible to resolve at the stage of constitutional choice. This problem of legitimation affects all instances of constitutional choice in which there are opposing views not only about the desired outcome of the process but also about the decision-making rules that govern constitutional choice
