York College of The City University of New York is one of eleven senior colleges in the City University of New York system. It is located in Jamaica, Queens in New York City. Founded in 1966, York was the first senior college founded under the newly formed CUNY system, which united several previously independent public colleges into a single public university system in 1961. The college is a member-school of Thurgood Marshall College Fund.Today, with an enrollment of more than 8,000 students, York serves as one of CUNY's leading liberal arts colleges, granting bachelor's degrees in more than 40 fields, including those in the Heath Professions, Nursing and a combined BS/MS degree in Occupational Therapy, among others. The York College Library subscribes to dozens of electronic resources, as well as print journals, to support the research needs of the faculty and students.Based on a study conducted by The Institute for College Access & Success , NerdScholar, a scholarship information organization and website, recently listed York College as the “US College with the lowest student debt in 2013.” The national survey chose York as number one on its top 20 list of colleges and universities both private and public.Marcia V. Keizs, a native of Kingston, Jamaica, became York College's 6th president in February 2005. Wikipedia.

Neuroscience is one of the most heavily experimental fields of biological and medical research. As such, statistical approaches have traditionally focused on testing specific predictions based upon well-focused hypotheses. However, neuroscience data are often derived from repeated measurements and stimulus type presentations with a limited number of subjects, some of which may have incomplete data per subject. Here we provide an introduction to a group of diverse and powerful statistical approaches, which we term the '5 Ms', which have been successfully used in other fields of biological research facing similar constraints. Specifically, we detail how M1: meta-analysis can combine, reconcile, and analyse between- and within-study results, M2: mixed-effects modelling is beneficial through replacing statistical tests involving pseudoreplication, M3: multiple imputation may be used to account for the biases caused by missing data arising from incomplete experimental protocols, and M4: model averaging from information-theoretic approaches allows to discriminate among alternative functional hypotheses. We also provide a brief introduction to Bayesian statistics using M5: Markov chain Monte Carlo (MCMC). Taken together, these approaches provide neuroscientists with a robust statistical toolbox containing elements that alleviate some of the analytical constraints generated by limited sample sizes, repeated subject use, and incomplete replicates of experimental manipulation. © 2010 Elsevier Ltd.

Mammalian target of rapamycin (mTOR) has been implicated as a sensor of nutrient sufficiency for dividing cells and is activated by essential amino acids and glucose. However, cells also require lipids for membrane biosynthesis. A central metabolite in the synthesis of membrane phospholipids is phosphatidic acid (PA), which is required for the stability and activity of mTOR complexes. Although PA is commonly generated by the phospholipase D-catalyzed hydrolysis of phosphatidylcholine, PA is also generated by diacylglycerol kinases and lysophosphatidic acid acyltransferases, which are at the center of phospholipid biosynthesis. It is proposed that the responsiveness of mTOR/TOR to PA evolved as a means for sensing lipid precursors for membrane biosynthesis prior to doubling the mass of a cell and dividing. © 2013 Elsevier Ltd.

We develop a general theory for a quantum-walk search on a star graph. A star graph has N edges each of which is attached to a central vertex. A graph G is attached to one of these edges, and we would like to find out to which edge it is attached. This is done by means of a quantum walk, a quantum version of a random walk. This walk contains O(N) steps, which represents a speedup over a classical search, which would require O(N) steps. The overall graph, star plus G, is divided into two parts, and we find that for a quantum speedup to occur, the eigenvalues associated with these two parts in the N→∞ limit must be the same. Our theory tells us how the initial state of the walk should be chosen, and how many steps the walk must make in order to find G. © 2014 American Physical Society.

Annual Review of Entomology | Year: 2013
Entomophagy is widespread among nonhuman primates and is common among many human communities. However, the extent and patterns of entomophagy vary substantially both in humans and nonhuman primates. Here we synthesize the literature to examine why humans and other primates eat insects and what accounts for the variation in the extent to which they do so. Variation in the availability of insects is clearly important, but less understood is the role of nutrients in entomophagy. We apply a multidimensional analytical approach, the right-angled mixture triangle, to published data on the macronutrient compositions of insects to address this. Results showed that insects eaten by humans spanned a wide range of protein-to-fat ratios but were generally nutrient dense, whereas insects with high protein-to-fat ratios were eaten by nonhuman primates. Although suggestive, our survey exposes a need for additional, standardized, data. © 2013 by Annual Reviews. All rights reserved.

Recently RNA localization has been appreciated as an essential post-transcriptional mechanism to program local proteome composition and function. Although RNA has been visualized using diverse techniques, the use of the bacteriophage MS2 method to encode genetically fluorescent RNA has revolutionized the study of RNA dynamics in living cells. Here, I highlight the strength of MS2 compared to other techniques, and how further evolution of this system will enable the visualization of RNA in the context of complex live-cell dynamics. Although the generation of MS2-fluorescence resonance energy transfer (FRET) and MS2-bifluorescence complementation (BiFC) will require further development, it has the potential to increase significantly the signal-to-noise ratio, which is the major obstacle to rapid live-cell imaging of RNA. © 2012 Elsevier Ltd.

In this critical review we highlight recent advances in the use of peptide- and protein-related materials as smart building blocks in nanotechnology. Peptides and proteins can be very practical for new material synthesis and device fabrications. For example, peptides and proteins have superior specificity for target binding as seen in the antibody recognition and this biological recognition function can be used to assemble them into specific structures and shapes in large scale, as observed in the S-layer protein assembly. Collagens are assembled from triple helix peptides in micron-size with precise recognition between peptides and these biological assemblies can undergo smart structural change with pH, ionic strength, temperature, electric/magnetic fields. In addition, assemblies of peptides can template complex 3D crystallization processes with catalytic function, thus enabling to grow various materials in physiological conditions at low temperature in aqueous solution. The biomimetic growth of nanomaterials in aqueous solution is extremely useful when they are applied to therapeutics and medical imaging in vivo since these nanomaterials will be well dispersed in bodies. Peptides also play significant roles in signal transduction pathways in cells. For example, neuropeptides are used as neurotransmitters between synapses and these peptides bind receptors on the surface of cells to cascade the signal transduction. These versatile functions of peptides are extremely practical and here we discuss them with examples of relevant applications such as nanoreactors, sensors, electronics, and stimulus-responsive materials. It should be noted that peptide/protein assemblies can be applied to build up micron-scale materials that still feature excellent nano-scale ensembles, which essentially bridges the nano-world and the micro-world (86 references). © 2010 The Royal Society of Chemistry.

Individuals with knee osteoarthritis, a painful debilitating joint disease affecting many aging adults, are commonly encouraged to pursue a variety of exercise regimens. However, very few studies have specifically focused on barriers and facilitators of exercise adherence as related to knee osteoarthritis. This review focuses on what is known about exercise adherence, as well as those factors that influence exercise adherence, both generally, and in the context of knee osteoarthritis. To this end, a wide array of related studies were retrieved and reviewed. The objective was to better understand the relationship between this disabling health condition and exercise, and factors that might specifically determine long-term exercise participation among this population. Results of this search revealed: 1) strong support for the application of exercise to allay the progression and/or severity of knee osteoarthritis and its consequences, but poor adherence rates in reality; 2) a vast array of disease-associated, as well as other exercise adherence barriers; 3) many recommendations for promoting exercise adherence including improving the nature of the patient-provider relationship, and the importance of individualized exercise prescriptions. It is concluded that life-long exercise is crucial for maximizing the well-being and function of adults with knee osteoarthritis, but recommendations to exercise are often pursued inconsistently. To encourage exercise adherence among this cohort, a comprehensive individualized assessment, active patient involvement in the decision-making process, and long-term monitoring are indicated. © 2012 Bentham Science Publishers.

Recently, researchers have debated two views on the connection between lifestyle and health. In the first, health-related lifestyles including tobacco and alcohol use, diet, and physical activity are seen as primary influences on health. In the second, social stratification is the dominant influence with lifestyles simply markers of social status. Neither approach leads to interventions that can reverse the world's most serious health problems. This article proposes that corporate practices are a dominant influence on the lifestyles that shape patterns of health and disease. Modifying business practices that promote unhealthy lifestyles is a promising strategy for improving population health. Corporations shape lifestyles by producing and promoting healthy or unhealthy products, creating psychological desires and fears, providing health information, influencing social and physical environments, and advancing policies that favor their business goals. Public officials and health professionals can promote health by advocating policies to modify these corporate practices. © 2012 Macmillan Publishers Ltd.

This study explored the nexus of home and school climate on the psychological distress of lesbian, gay, bisexual, and transgender (LGBT) homeless youth, as well as their experiences during high school. Of the LGBT homeless youth (N = 89) surveyed, 39.3% reported not completing high school. Most participants did not seek support from school staff nor did they report attending a school with a Gay-Straight Alliance. Significantly higher levels of psychological distress were found among high school graduates and those reporting LGBT harassment at home; however, harassment experienced at school was not statistically related to psychological distress. Findings are discussed. © 2014 Taylor & Francis Group, LLC.

‘Food sovereignty’ has become a mobilizing frame for social movements, a set of legal norms and practices aimed at transforming food and agriculture systems, and a free-floating signifier filled with varying kinds of content. Canonical accounts credit the Vía Campesina transnational agrarian movement with coining and elaborating the term, but its proximate origins are actually in an early 1980s Mexican government program. Central American activists nonetheless appropriated and redefined it in the late 1980s. Advocates typically suggest that ‘food sovereignty’ is diametrically opposed to ‘food security’, but historically there actually has been considerable slippage and overlap between these concepts. Food sovereignty theory has usually failed to indicate whether the ‘sovereign’ is the nation, region or locality, or ‘the people’. This lack of specificity about the sovereign feeds a reluctance to think concretely about the regulatory mechanisms necessary to consolidate and enforce food sovereignty, particularly limitations on long-distance and international trade and on firm and farm size. Several regulatory possibilities are mentioned and found wanting. Finally, entrenched consumer needs and desires related to internationally-traded products – from coffee to pineapples – imply additional obstacles to the localisation of production, distribution and consumption that many food sovereignty proponents support. © 2014 Taylor & Francis.
