Spectrum-imaging is a useful technique for comparing different processing methods on very large data sets which are identical for each method. This paper is concerned with comparing methods of electron energy-loss spectroscopy (EELS) quantitative analysis on the Al-Li system. The spectrum-image analyzed here was obtained from an Al-10at%Li foil aged to produce δ' precipitates that can span the foil thickness. Two 1024 channel EELS spectra offset in energy by 1 eV were recorded and stored at each pixel in the 80x80 spectrum-image (25 Mbytes). An energy range of 39-89eV (20 channels/eV) are represented. During processing the spectra are either subtracted to create an artifact corrected difference spectrum, or the energy offset is numerically removed and the spectra are added to create a normal spectrum. The spectrum-images are processed into 2D floating-point images using methods and software described in [1].

Preparation of appropriate photographs is absolutely essential in conveying paleontological information. The effort expended in adequate cleaning and preparation of specimens is not only reflected in exposing the detail of material so that it can be properly described but also in permitting the morphologic information to be transmitted to others through photography. Therefore the purpose of this chapter is to describe the general procedures involved in preparing high quality, publishable photographs because special techniques related to photography of microfossils will be treated elsewhere, the emphasis within this chapter will be upon photography of macrofossils, specimens large enough to be photographed using a normal spectrum of photographic lenses and extension tubes. Because nearly all paleontological material is illustrated as black and white photographs, no reference will be made to the preparation of color illustrations.

Biracial individuals threaten the distinctiveness of racial groups because they have mixed-race ancestry, but recent findings suggest that exposure to biracial-labeled, racially ambiguous faces may positively influence intergroup perception by reducing essentialist thinking among Whites ( Young, Sanchez, & Wilton, 2013 ). However, biracial exposure may not lead to positive intergroup perceptions for Whites who are highly racially identified and thus motivated to preserve the social distance between racial groups. We exposed Whites to racially ambiguous Asian/White biracial faces and measured the perceived similarity between Asians and Whites. We found that exposure to racially ambiguous, biracial-labeled targets may improve perceptions of intergroup similarity, but only for Whites who are less racially identified. Results are discussed in terms of motivated intergroup perception.

BACKGROUND: Appropriate nutrition is important to maintain health, growth, and development of adolescent athlete performance. OBJECTIVE: To evaluate the impact of nutritional intervention (NI) promoting Mediterranean diet (MD), on food consumption, and adherence to MD, in scholar adolescent athletes. METHODS: Eighty athletes (Females/Males, 39/41) aged 15±1 years participated to NI. MD Adherence was assessed, using Kidmed index, at baseline, and at 6 months. Food intake was evaluated by 24-hour recall at baseline, and at four NI times. RESULTS: At baseline, 61% of athletes had poor MD adherence, and after NI, this value decreased to 10%. At 6 months of NI, 73% of males vs 46% of females had good MD adherence (≥8). Energy intake represented 2369 Kcal/d, at baseline, and was less than recommended value. After NI, significant increase was observed in energy intake (p = 0.001). Mean fiber intake (19 and 21 g/d in females and males, respectively) was less than adequate intake (26/38 g/d), but increased after NI (p = 0.000). Enhancement was noted in total, and complex carbohydrates, and total proteins, and values were increased with time (p = 0.000, p = 0.000, p = 0.003). CONCLUSION: Nutritional intervention, based on Mediterranean diet, improves total energy, and macronutrients intake, and increases MD adherence scores in adolescents athletes.

I am writing this analytical appreciation of cultura panamericana, or pan-American culture, to propose a wider recognition of how its historical linkages and contemporary manifestations confront colonialism, honor indigenous roots, and reflect multiple, mixed-race identities. Although often mediated by transnational pop-culture industries, expressive cultural forms such as art and music articulate resonant themes that connect US Latinos and Latinas to Latin Americans, pointing the way toward a hemispheric imaginary. In US murals, for example, whether in the Chicago neighborhood of Pilsen or the Los Angeles neighborhood of Highland Park, pan-American expressive culture offers alternative representations by embracing indigeneity, and it creates a sense of place by tropicalizing urban spaces.

This paper presents an overview of multiracial student organizing and organizations on college campuses. The authors address common challenges that multiracial student organizations face in higher education, how student affairs staff can challenge institutional practices that perpetuate monoracism, and how to support and empower mixed race students to effectively develop strong leadership skills. Several recommendations for working through political and administrative hurdles are also provided.
