New York City, NY, United States

The City University of New York is the public university system of New York City. It is the largest urban university in the United States, consisting of 24 institutions: 11 senior colleges, seven community colleges, the William E. Macaulay Honors College at CUNY, the CUNY Baccalaureate for Unique and Interdisciplinary Studies Program at the Graduate Center, the doctorate-granting Graduate School and University Center, the City University of New York School of Law, CUNY Graduate School of Journalism, the CUNY School of Public Health and the Sophie Davis School of Biomedical Education. More than 270,000 degree-credit students and 273,000 continuing and professional education students are enrolled at campuses located in all five New York City boroughs. Its administrative offices are in mid-town Manhattan.The university has one of the most diverse student bodies in the United States, with students hailing from 208 countries. The black, white and Hispanic undergraduate populations each comprise more than a quarter of the student body, and Asian undergraduates make up 18 percent. Fifty-eight percent are female, and 28 percent are 25 or older. CUNY graduates include 13 Nobel laureates, a U.S. Secretary of State, a Supreme Court Justice, several New York City mayors, members of Congress, state legislators, scientists and artists.CUNY is the third-largest university system in the United States, in terms of enrollment, behind the State University of New York , and the California State University system. CUNY and SUNY are separate and independent university systems, although both are public institutions that receive funding from New York State. CUNY, however, is additionally funded by the City of New York. Wikipedia.

Objectives: I used longitudinal data to consider the relationship between the neighborhood food environment and adult weight status. Methods: I combined individual-level data on adults from the 1998 through 2004 survey years of the National Longitudinal Survey of Youth 1979 with zip code-level data on the neighborhood food environment. I estimated ordinary least squares models of obesity, body mass index (BMI), and change in BMI. Results: For residents of urban areas, the neighborhood density of small grocery stores was positively and significantly related to obesity and BMI. For individuals who moved from a rural area to an urban area over a 2-year period, changes in neighborhood supermarket density, small grocery store density, and full-service restaurant density were significantly related to the change in BMI over that period. Conclusions: Residents of urban neighborhoods with a higher concentration of small grocery stores may be more likely to patronize these stores and consume more calories because small grocery stores tend to offer more unhealthy food options than healthy food options. Moving to an urban area may expose movers to a wider variety of food options that may influence calorie consumption.

Motivated by the indications of a possible deficit of muon tracks in the first three-year equivalent data set of IceCube we investigate the possibility that the astrophysical (anti)neutrino flux (in the PeV energy range) could originate from β-decay of relativistic neutrons. We show that to accommodate IceCube observations it is necessary that only about 1% to 10% of the emitted cosmic rays in the energy decade 108.5 ECR/GeV 109.5, yielding antineutrinos on Earth (105.5 Eν¯/GeV 106.5), are observed. Such a strong suppression can be explained assuming magnetic shielding of the secondary protons which diffuse in extragalactic magnetic fields of strength 10 B/nG 100 and coherence length Mpc. © 2015 American Physical Society.

Aromatic peptide amphiphiles are gaining popularity as building blocks for the bottom-up fabrication of nanomaterials, including gels. These materials combine the simplicity of small molecules with the versatility of peptides, with a range of applications proposed in biomedicine, nanotechnology, food science, cosmetics, etc. Despite their simplicity, a wide range of self-assembly behaviours have been described. Due to varying conditions and protocols used, care should be taken when attempting to directly compare results from the literature. In this review, we rationalise the structural features which govern the self-assembly of aromatic peptide amphiphiles by focusing on four segments, (i) the N-terminal aromatic component, (ii) linker segment, (iii) peptide sequence, and (iv) C-terminus. It is clear that the molecular structure of these components significantly influences the self-assembly process and resultant supramolecular architectures. A number of modes of assembly have been proposed, including parallel, antiparallel, and interlocked antiparallel stacking conformations. In addition, the co-assembly arrangements of aromatic peptide amphiphiles are reviewed. Overall, this review elucidates the structural trends and design rules that underpin the field of aromatic peptide amphiphile assembly, paving the way to a more rational design of nanomaterials based on aromatic peptide amphiphiles.

The surfactant-micelle-templating method has revolutionized the synthesis of high-surface-area materials with mesopores (diameter 2-50 nm) that have well-defined shapes and sizes. One of the major benefits of this method is the ability to tailor the pore size by manipulating the size of the templating micelles. The uniform pores typically form ordered arrays. Although the choice of surfactant can tune the size of the micelles, it is more convenient to use a single surfactant and tailor the micelle size by adding a swelling agent. Unfortunately, the swelling agent tends to induce disorder or heterogeneity in the resulting structures, which can make this approach difficult to implement.We hypothesized that the swelling agents that are moderately solubilized within themicelles of a particular surfactant could generate well-defined micelle-templated structures with significantly enlarged pores. Using this idea, we could judiciously select candidate swelling agents from families of compounds whose extent of solubilization in the surfactant micelles systematically changes with variations in the compound structure. Alkyl-substituted benzenes proved very useful as swelling agents, because their extent of solubilization in micelles of common Pluronic surfactants (EO mPO nEO m; EO = ethylene oxide, PO = propylene oxide) significantly increases as the number or size of alkyl substituents decreases. On the basis of these principles, we identified 1,3,5- triisopropylbenzene and cyclohexane as swelling agents for the synthesis of ultralarge-pore SBA-15 silica (pore diameter up to 26 nm) and organosilicas with 2-D hexagonal structures of cylindrical mesopores. Moreover, we used xylene, ethylbenzene, and toluene as swelling agents for the synthesis of large-pore (pore diameter up to 37 nm) face-centered cubic silicas and organosilicas with spherical mesopores. During the early stages of the synthesis, the entrances to large cylindrical and spherical mesopores of these materials were much smaller than the inner pore diameter. Therefore we can often use calcination at sufficiently high temperatures (400-950-C) to produce closed-pore silicas. Using hydrothermal treatments, we can obtain materials with large pore entrance sizes. In Pluronic-templated synthesis, we observed the propensity for formation of single-micelle-templated nanoparticles as the ratio of the framework precursor to surfactant decreased, and this process afforded organosilica nanotubes and uniform hollow spheres with inner diameters up to ∼21 nm. Consequently, the adjustment of variables in the micelle-templated synthesis allows researchers to tailor the pore size and connectivity and to form either periodic pore arrays or individual nanoparticles. © 2012 American Chemical Society.

The internship is an essential part of doctoral training in professional psychology. Most students access internships through the annual match sponsored by the Association of Psychology Postdoctoral and Internship Centers (APPIC). For two decades the match has seen an increasing shortfall of internship positions relative to applicants, exceeding 650 unmatched clinical students as of 2013. Efforts to solve this problem have not met appreciable success. This review discusses the structure of the internship placement process, including and beyond the APPIC match, and identifies the reasons for the failed efforts, which lie principally in the varied standards for an acceptable internship among doctoral programs. Efforts to establish a common standard and the need for a governance structure to enforce whatever standard is agreed upon are discussed. Projections for the future of the placement process and the imbalance are sketched, and links to other issues in the field are briefly reviewed. © 2014 by Annual Reviews.
