DNA and pacific commensal models : applications, construction, limitations, and future prospects

Components of the Pacific transported landscape have been used as proxies to trace the prehistoric movement of humans across the Pacific for almost two decades. Analyses of archaeological remains and DNA sequences of plants, animals, and microorganisms moved by or with humans have contributed to understanding prehistoric migration, trade, exchange, and sometimes revealed the geographic origins of particular plants and animals. This paper presents the basic elements of a DNA-based commensal model and discusses the phylogenetic and population genetic approaches these models employ. A clear delineation of the underlying assumptions of these models and the background information required to construct them have yet to appear in the literature. This not only provides a framework with which to construct a commensal model but also highlights gaps in current knowledge. The ways in which commensal models have enriched archaeological reconstructions will be highlighted, as will their current limitations. With these limitations in mind, options will be outlined for augmenting commensal models through the application of established techniques and new technologies in order to provide the best tools for reconstructing ancient human mobility and behavior in the Pacific and beyond

Topical Review: Building Competency: Professional Skills for Pediatric Psychologists in Integrated Primary Care Settings

Objectives In the midst of large-scale changes across our nation’s health care system, including the Affordable Care Act and Patient-Centered Medical Home initiatives, integrated primary care models afford important opportunities for those in the field of pediatric psychology. Despite the extensive and growing attention, this subspecialty has received in recent years, a comprehensive set of core professional competencies has not been established. Methods A subset of an Integrated Primary Care Special Interest Group used two well-established sets of core competencies in integrated primary care and pediatric psychology as a basis to develop a set of integrated pediatric primary care-specific behavioral anchors. Conclusions The current manuscript describes these behavioral anchors and their development in the context of professional training as well as with regard to Triple Aim goals and securing psychology’s role in integrated pediatric primary care settings

Integrated Behavioral Health Training in Counselor Education: A Call to Action

The American healthcare system is beginning to adopt an integrated behavioral health model as a way to meet the ever-changing and holistic needs of patients by creating opportunities for collaboration among medical and behavioral health professionals. Professional counselors play a vital role in integrative behavioral health through their meaningful participation on interdisciplinary healthcare teams. Professional counselors are key to any interdisciplinary team because they embrace a biopsychosocial wellness perspective and have undergone clinical and academic training. However, many counseling programs do not specifically educate or train counselors in how to work in integrated care settings. As such, counselor educators must adapt to this evolving system of healthcare by providing students with didactic and experiential learning opportunities to promote competence and readiness to practice in this new wave of healthcare

Ethnic pride and cultural values promote positive youth development in a conceptual replication of the Five Cs model.

The current study examined the Five Cs model of positive youth development (PYD; Lerner et al., 2005) in U.S. Mexican-origin youth (N = 674, 50% female) and tested the extent to which ethnic pride, familismo, and respeto, as an index of cultural orientation, predicted PYD across midadolescence. PYD was modeled using a bifactor structure, which defined global PYD and the Five Cs (Caring, Character, Competence, Confidence, and Connection) using theoretically similar measures matched to the conceptual definitions of the Cs. Tests of longitudinal invariance of the bifactor model at ages 14 and 16 established scalar invariance, providing support for the structure and stability of the Five Cs and global PYD using the theoretically similar measures across time. Adolescents cultural orientation (latent factor incorporating familismo, respeto, and ethnic pride) at age 14 was positively associated with the Five Cs within and across time. Greater cultural orientation at age 14 predicted increased global PYD across ages 14 and 16. The contribution of cultural orientation to the PYD across midadolescence did not differ by adolescent gender or nativity. These findings demonstrate the robust nature and stability of the Five Cs model of PYD and provide novel evidence that ethnic pride, familismo, and respeto promote greater PYD in Mexican-origin youth during midadolescence.

Global population divergence and admixture of the brown rat (Rattus norvegicus)

Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the 1500s, suggesting their range expansion was a response to relatively recent increases in global trade. We inferred the global phylogeography of brown rats using 32 k SNPs, and detected 13 evolutionary clusters within five expansion routes. One cluster arose following a southward expansion into Southeast Asia. Three additional clusters arose from two independent eastward expansions: one expansion from Russia to the Aleutian Archipelago, and a second to western North America. Westward expansion resulted in the colonization of Europe from which subsequent rapid colonization of Africa, the Americas and Australasia occurred, and multiple evolutionary clusters were detected. An astonishing degree of fine-grained clustering between and within sampling sites underscored the extent to which urban heterogeneity shaped genetic structure of commensal rodents. Surprisingly, few individuals were recent migrants, suggesting that recruitment into established populations is limited. Understanding the global population structure of R. norvegicus offers novel perspectives on the forces driving the spread of zoonotic disease, and aids in development of rat eradication programmes

Systems Integration Model: Combining areas of human health, animal health and economic development

According to the World Health Organization (1999), more than 90% of the estimated 36 million people with HIV/AIDS are living in developing countries with agricultural pursuits as both their primary means of income and food source, suggesting a critical relationship between the three areas of human health, animal health and agricultural economic development in emerging world areas. While there are organizations that provide treatment, intervention or aid in terms of one or more of these areas, a review of the literature did not reveal any which deal with the three in the aggregate. This paper examines the correlations that exist between human health, animal health, and economic development and sets forth a trivariate approach known as the Systems Integration Model (SIM), as the proposed interventional concept. The SIM intervention concept targets all three areas as opposed to being singularly focused on one, which has widespread implications for organizational responses to diseases of poverty, such as HIV/AIDS.Master of Public Healt

Clinical Use of the Low-Molecular-Weight Heparins in Cancer Patients: Focus on the Improved Patient Outcomes

Patients with malignant neoplastic diseases represent a high-risk population relative to thromboembolic disease. With the advent of improved and accessible diagnostic technology, for example, ultrasound and/or spiral CT scans, timely diagnosis of venous thromboembolic events (VTE) is readily accomplished. The introduction of low-molecular-weight heparin (LMWH) approximately two decades ago (in contrast to unfractionated heparin and vitamin K antagonists) has provided a class of agents with a favorable therapeutic index. In the review to follow, the literature regarding the use of LMWH in oncologic patient populations is summarized. Topics addressed include prophylaxis, and treatment as well as consideration of the potential anti-neoplastic properties of this class of drugs

Sensitivity of estuaries to compound flooding.

Fluvial and surge-tide extremes can occur synchronously resulting in compound flooding in estuaries, greatly intensifying the hazard. This flood risk has the potential to increase in the future as the frequency, phasing and/or intensity of these drivers change. Improved understanding of how extreme fluvial discharge and surge-tides interact will help inform future flood mitigation methodology. In this paper, therefore, we resolve for the first time intra-estuary sensitivities to fluvial and surge-tide extremes, for two contrasting UK estuaries (Humber and Dyfi). Model simulations at hyper-spatial resolution (< 50 m) using a 2D hydrodynamic model predicted compound flooding hazards based on: (1) present-day extreme events (worst on record); (2) present-day extreme events with shifted timings of the drivers to maximise flooding; and (3) modified drivers representing projected climate change. We found that in a small estuary with short-duration, high-intensity fluvial inputs (Dyfi), flood extent is sensitive to the relative timing of the fluvial and surge-tide drivers. In contrast, the relative timing of these drivers did not affect flooding in a larger estuary with a slower fluvial response to rainfall (Humber). In the Humber, extreme fluvial inputs during a compound hazard actually reduced maximum water depths in the outer estuary, compared with a surge-tide-only event. Projected future changes in these drivers by 2100 will increase compound flooding hazards: simulated sea-level rise scenarios predicted substantial and widespread flooding in both estuaries. However, projected increases in surge-tide behaved differently to sea-level rise of the same magnitude, resulting in a greater seawater influx and more flooding. Increased fluvial volumes were the weakest driver of estuarine flooding. In this paper we show how these interactions are complex and how the hydrodynamics vary considerably between different estuaries and sites within estuaries, making it difficult to generalise, use probabilistic or use 1D approaches for assessing compound flooding hazards. Hence, we contribute new knowledge and methods for catchment-to-coast impact modelling used for flood mitigation strategies
