The Overlap Package

Camera traps - cameras linked to detectors so that they fire when an animal is present - are a major source of information on the abundance and habitat preferences of rare or shy forest animals. Modern cameras record the time of the photo, and the use of this to investigate diel activity patterns was immediately recognised (Gri?ffiths and van Schaik, 1993). Initially this resulted in broad classfication of taxa as diurnal, nocturnal, crepuscular, or cathemeral (van Schaik and Gri?ths, 1996). More recently, researchers have compared activity patterns among species to see how overlapping patterns may relate to competition or predation (Linkie and Ridout, 2011; Carver et al., 2011; Ramesh et al., 2012; Carter et al., 2012; Kamler et al., 2012; Ross et al., 2013). Ridout and Linkie (2009) presented methods to fit kernel density functions to times of observations of animals and to estimate the coe?cient of overlapping, a quantitative measure ranging from 0 (no overlap) to 1 (identical activity patterns). The code they used forms the basis of the overlap package. Although motivated by the analysis of camera trap data, overlap could be applied to data from other sources such as data loggers, provided data collection is carried out around the clock. Nor is it limited to diel cycles: tidal cycles or seasonal cycles, such as plant flowering or fruiting or animal breeding seasons could also be investigated

Giving Vulnerable Students Their Due: Implementing Due Process Protections for Students Referred from Schools to the Justice System

There are two primary ways that schools can funnel children into the “school-to-prison pipeline.” The first is by simply removing children from school via expulsions and suspensions, which increase students’ chances of dropping out and getting in trouble with the law. The Supreme Court, recognizing the serious consequences of being forced out of school, has held that expulsions and long-term suspensions constitute deprivations of students’ property interest in their educations and liberty interest in their reputations. Thus, schools seeking to expel or suspend students must provide them with basic due process protections. But schools can also refer students directly to the justice system by having police officers arrest students or issue citations at school. Under current law, these students are not entitled to any due process protections at the point of arrest or referral. This Note argues that the absence of due process protections for students who are arrested or referred to the justice system at school is incompatible with the Supreme Court’s procedural due process jurisprudence in general and its decision in Goss v. Lopez in particular. The same property and liberty interests that the Court identified as worthy of protection in Goss are implicated by in-school arrests and referrals. Therefore, school administrators who intend to have a child arrested or referred to the justice system should be required to provide students with oral notice of the accusation against them and an opportunity to respond. After an arrest or referral, the school should provide students and their parents with written notice of the arrest or referral and the rationale for the action. These measures will not unduly burden administrators or schools, but they will provide meaningful protections for students

Learning-Focused Leadership and Leadership Support: Meaning and Practice in Urban Systems

Imaging slow failure in triaxially deformed Etna basalt using 3D acoustic-emission location and X-ray computed tomography

We have deformed basalt from Mount Etna (Italy) in triaxial compression tests under an effective confining pressure representative of conditions under a volcanic edifice (40 MPa), and at a constant strain rate of 5 similar to 10(-6) s(-1). Despite containing a high level of pre-existing microcrack damage, Etna basalt retains a high strength of 475 MPa. We have monitored the complete deformation cycle through contemporaneous measurements of axial strain, pore volume change, compressional wave velocity change and acoustic emission (AE) output. We have been able to follow the complete evolution of the throughgoing shear fault without recourse to any artificial means of slowing the deformation. Locations of AE events over time yields an estimate of the fault propagation velocity of between 2 and 4 mm. s(-1). We also find excellent agreement between AE locations and post-test images from X-ray microtomography scanning that delineates deformation zone architecture

A community-engaged infection prevention and control approach to Ebola.

The real missing link in Ebola control efforts to date may lie in the failure to apply core principles of health promotion: the early, active and sustained engagement of affected communities, their trusted leaders, networks and lay knowledge, to help inform what local control teams do, and how they may better do it, in partnership with communities. The predominant focus on viral transmission has inadvertently stigmatized and created fear-driven responses among affected individuals, families and communities. While rigorous adherence to standard infection prevention and control (IPC) precautions and safety standards for Ebola is critical, we may be more successful if we validate and combine local community knowledge and experiences with that of IPC medical teams. In an environment of trust, community partners can help us learn of modest adjustments that would not compromise safety but could improve community understanding of, and responses to, disease control protocol, so that it better reflects their 'community protocol' (local customs, beliefs, knowledge and practices) and concerns. Drawing on the experience of local experts in several African nations and of community-engaged health promotion leaders in the USA, Canada and WHO, we present an eight step model, from entering communities with cultural humility, though reciprocal learning and trust, multi-method communication, development of the joint protocol, to assessing progress and outcomes and building for sustainability. Using examples of changes that are culturally relevant yet maintain safety, we illustrate how often minor adjustments can help prevent and treat the most serious emerging infectious disease since HIV/AIDS

Network analysis of conjunctively operated ground water-surface water systems

The concept of network models is introduced and a general network model for a multiple purpose, multiple unit water resource system is developed. The "out-of-kilter" algorithm is then presented as a solution technique for network flow problems. A model for preliminary screening of alternatives for water supply from conjunctive use of ground water and surface water in the Kaskaskia River Basin in Illinois is presented and analyzed. The results from the analysis demonstrate how the network analysis procedures can be used to determine optimum investment plans, to test policy constraints, and to develop policies for future development and future constraints.U.S. Geological SurveyU.S. Department of the InteriorOpe
