STRUCTURE OF STABLE MINIMAL HYPERSURFACES IN A RIEMANNIAN MANIFOLD OF NONNEGATIVE RICCI CURVATURE

Abstract. Let N be a complete Riemannian manifold with nonnegativeRicci curvature and let M be a complete noncompact oriented stableminimal hypersurface in N. We prove that if M has at least two endsandR M |A| 2 dv = ∞, then M admits a nonconstant harmonic functionwith ﬁnite Dirichlet integral, where Ais the second fundamental form ofM. We also show that the space of L 2 harmonic 1-forms on such a stableminimal hypersurface is not trivial. Our result is a generalization of oneof main results in [12] because if N has nonnegative sectional curvature,then M admits no nonconstant harmonic functions with ﬁnite Dirichletintegral. And our result recovers a main theorem in [3] as a corollary. 1. IntroductionThe classical Bernstein theorem asserts that an entire minimal graph in R 3 must be planar. This theorem was subsequently generalized to higher dimen-sions by several authors, cf. [1], [5], [9], [17]. It is now known [2], [17] that anentire n-dimensional minimal graph in R n+1 must be given by a linear functionover R
Calcareous Nannofossils: Leg 19 of the Deep Sea Drilling Project

Calcareous nannofossils are the minute (l-2Qu) skeletal remains of planktonic members of the golden brown algae. They are essentially tropical or subtropical organisms but cosmopolitan and high-latitude species are known (Edwards, 1968a, b; Mclntyre, Be, and Roche, 1970; Worsley and Martini, 1970;). However, remains are not common in high-latitude sediments. Therefore, it is not surprising that the Neogene assemblages found in the North Pacific and Bering Sea have low population density and species diversity. Paleocene and Maestrichtian assemblages from the North Pacific are more diverse, suggesting more moderate global climate, and/or large translatitudinal plate motion. In the Bering Sea, six sites were drilled (Figure 1) and the oldest sediments cored are Miocene. Most analyzed samples are completely devoid of calcareous nannofossils and little interpretation is offered here of the significance of the few fossiliferous samples, other than to note in the site reports where they occur. The reader is referred to the site reports and to the foraminifera chapter in this volume for detailed paleoclimatic interpretation. In the North Pacific, five sites (Figure 1) were drilled, two of which contain more diversified nannofloras than any site in the Bering Sea. Meiji Guyot (Site 192) at the northwestern terminus of the Emperor seamount chain contains a somewhat impoverished Neogene assemblage underlain by progressively richer ones of Oligocene, Eocene, and Maestrichtian age. The Mesozoic-Cenozoic boundary was cored here, thereby demonstrating the complete absence of Paleocene strata at this site. The Gulf of Alaska (Site 183) is devoid of Neogene nannofossils and was apparently below the carbonate compensation depth (CCD) throughout its Neogene depositional history. Below, extremely sparse nannofloras occur in a thick turbidite sequence between a thin (1 to 20 meters) Oligocene nannofossil-rich chalk bed and a 1to 2-meter-thick upper lower Eocene nannofossil-rich limestone bed. The other North Pacific sites (Figure 1) contain no nannofossils.
Influence of bird-induced soil fertility gradients on oomycete distribution in a threatened Quercus suber population

Cork oaks are considered keystone structures in the ecosystem of the stabilised sands of the Donana National Park. These remnant big trees are threatened by nesting of colonial waterbirds (whose debris induce deep soil chemical changes) and by two pathogenic oomycetes, Phytophthora cinnamomi and Pythium spiculum. We analyzed the distribution of seven oomycete species in soils along a bird influence gradient. Canonical analysis revealed a significant relationship between the composition of the oomycete community and soil chemical variables closely related to bird debris accumulation (soil N and P contents). Some Pythium spp. were able to live in heavily fertilized soils, while pathogenic species did not thrive in that soils. A separate analysis showed that the presence and abundance of P. cinnamomi and P. spiculum in the rizosphere was significantly lower in trees with moderate or high bird influence. We concluded that 1) natural fertilization by bird faeces induced soil changes affecting pathogenic oomycetes behaviour; 2) as long as these bird-induced soil changes were no too extreme to cause dieback by themselves, they could prevent the spread and tree decline events caused by soil pathogens.
English Language Learner Boys and Girls Reading and Math Achievement as a Function of Early-Exit and Late-Exit Bilingual Programs: A Multiyear, Statewide Analysis

We examined the reading and math performance of English Language Learner boys and girls in Grades 3, 4, 5, and 6 as a function of early-exit or late-exit transitional bilingual education program. Texas Assessment of Knowledge and Skills Reading and Mathematics scores of all English Language Learner boys and girls who were enrolled in either early-exit or late-exit bilingual education programs were analyzed for the 2008-2009, 2009-2010, and 2010-2011 school years. Results were not consistent across reading and math, across the 4 grade levels, and across the 3 school years. On the TAKS Reading test, 5 instances were present in which statistically significant differences were revealed for boys and 11 for girls. On the TAKS Mathematics test, 8 statistically significant results were revealed for boys and 6 for girls. These statistically significant differences were not consistently in favor of either the early-exit or the late-exit bilingual education programs. Moreover, the differences that were present reflected small to trivial effect sizes. As such, neither the early-exit nor the late-exit bilingual education program was demonstrated to be more effective than its counterpart.
Study on the Organizational Pattern of Mental Lexicon for Chinese ESL College Students of Science

This paper tries to provide both theoretical and pedagogical evidence on the organizational pattern of L2 mental lexicon for Chinese ESL learners and teachers. The evidence results from a carefully designed empirical research where the subjects are ESL students with different language proficiencies from software school of DUT. Results show that the organizational pattern of Chinese ESL learners’ mental lexicon is a mix of semantic and non-semantic network, and it is rather dynamic. Efforts of reconstructing the lexicon network are necessary.
Endogenous Determinants of Income and Consumption in Post-War Northern Mozambique 1

The paper analyses the endogenous determinants of poverty in post-war Mozambique. The analysis extends the Binswanger and McIntire (1987) farm household model to the post-war economy, identifying how war changes household endowments, coping strategies and welfare. The econometric analysis using IV-techniques on a farm household dataset identifies war to be a strong but indirect cause of post-war poverty traps. Contrary to previous studies suffering from misspecification error by ignoring the war effects, area farmed and market participation reduce poverty while cotton adoption increases poverty. Policy implications include focusing reconstruction aid on food crop inputs and markets.

Kähler-Einstein metrics singular along a smooth divisor

In this note we discuss some recent and ongoing joint work with Thalia Jeffres concerning the existence of Kahler-Einstein metrics on compact Kahler manifolds which have a prescribed incomplete singularity along a smooth divisor D. We shall begin with a general discussion of the problem, and give a rough outline of the 'classical' proof of existence in the smooth case, due to Yau and Aubin, where no singularities are prescribed. Following this is a discussion of the geometry of the conical or edge singularities and then some discussion of the new elements of the proof in this context. 1. Background material. Let (X,^o) be a compact Kahler manifold of complex dimension n. Thus if UJQ is the corresponding Kahler form, then d^o = 0 and [0:0] is a class in ^^(X). A familiar question in geometric analysis is to find canonical metrics on a manifold. In this setting, this is commonly regarded as the search for Kahler-Einstein (KE) metrics. More specifically, a Kahler metric g on X is said to be KE if its Ricci tensor is a multiple of the metric. Using the complex structure J to turn the Ricci tensor into a (1, l)-form p = p g , then we ask that
Can the Okhotsk Plate be discriminated from the North American plate

The plate geometry in northeast Asia has been a long-standing question, with a major issue being whether the Sea of Okhotsk and northern Japanese islands are better regarded as part of the North American plate or as a separate Okhotsk plate. This question has been difficult to resolve, because earthquake slip vectors along the Kuril and Japan trenches are consistent with either Pacific-North America or Pacific-Okhotsk plate motion. To circumvent this difficulty, we also use slip vectors of earthquakes along Sakhalin Island and the eastern margin of the Japan Sea and compare them to the predicted Eurasia-Okhotsk and Eurasia-North America motions. For a model with a separate Okhotsk plate, we invert 10 Eurasia-Okhotsk and 255 Pacific-Okhotsk slip vectors with Pacific-North America and Eurasia-North America NUVEL-1 data. Alternatively, for a model without an Okhotsk plate, those Eurasia-Okhotsk and Pacific-Okhotsk data are regarded as Eurasia-North America and Pacific-North America data, respectively. The model with an Okhotsk plate fits the data better than one in which this region is treated as part of the North American plate. Because the improved fit exceeds that expected purely from the additional plate, the data indicate that the Okhotsk plate can be resolved from the North American plate. The motions on the Okhotsk plate's boundaries predicted by the best fitting Euler vectors are generally consistent with the recent tectonics. The Eurasia-Okhotsk pole is located at northernmost Sakhalin Island and predicts right-lateral strike slip motion on the NNE striking fault plane of the May 27, 1995, Neftegorsk earthquake, consistent with the centroid moment tensor focal mechanism and the surface faulting. Along the northern boundary of the Okhotsk plate, the North America-Okhotsk Euler vector predicts left-lateral strike slip, consistent with the observed focal mechanisms. On the NW boundary of the Okhotsk plate, the Eurasia-Okhotsk Euler vector predicts E-W extension, discordant with the limited focal mechanisms and geological data. This misfit may imply that another plate is necessary west of the Magadan region in southeast Siberia, but this possibility is hard to confirm without further data, such as might be obtained from space-based geodesy.
From Puebla to East Harlem: healthcare for a rapidly emerging community

In the winter of 1998, the first of many Mexican families arrived at one of New York City’s Health and Hospitals Corporation clinics in East Harlem. This paper traces the author’s 10-year experience of addressing and serving this unique community as director of this clinic. Finding a most willing ally in the New York City Mexican Consulate, which arranged visits to Mexican healthcare centres in California, Chicago and Mexico, he acquired the cultural competencies that allowed him to make appropriate adjustments to his clinic’s practice. At Oakland’s La Clinica de La Raza (‘the Clinic of the Race’ – that is, Mexican race), family structure and machismo were elucidated. In Chicago, the mental effects of emigration were depicted. However, it was not until the author visited Mexico that the full picture emerged. Socio-cultural values with regard to the experience and expression of illness, including gender roles and stoicism, were demonstrated. Systems and structures of healthcare networks, as well as patient expectations, were identified. Conditions that included obesity, diabetes, asthmaand mental illness were explored at Mexico’s referral centre, the National Institute of Health. First-hand knowledge was brought back and incorporated into the expanding family health centre. As Mexicans came to represent nearly onethirdof its patient population, the centre was rededicated and renamed La Clinica del Barrio (the clinic of the neighbourhood). It is now recognised by the State of New York Legislature as providing community-responsive healthcare for the people ofEast Harlem. The paper outlines one particular approach to the achievement of culturally competent healthcare, andcloses by linking this development to the broader aims of the Office of Minority Health.
DNA and allozyme markers provide concordant estimates of population differentiation: analyses of U.S. and Canadian populations of Yukon River fall-run chum salmon (Oncorhynchus keta)

Although the number of genetic markers available for fisheries research has steadily increased in recent years, there is limited information on their relative utility. In this study, we compared the preformance of different iclassesi of genetic markers (mitochondrial DNA (mtDNA), nuclear DNA (nDNA), and allozymes) in terms of estimating levels and partitioning of genetic variation and of the relative accuracy and precision in estimating population allocations to mixed-stock fisheries. Individuals from eight populations of fall-run chum salmon (Oncorhynchus keta) from the Yukon River in Alaska and Canada were assayed at 25 loci. Significant differences in mitochondrial haplotype and nuclear allele frequencies were observed among five drainages. Populations from the U.S.nCanada border region were not clearly distinguishable based on multilocus allele frequencies. Although estimates of total genetic diversities were higher for the DNA loci (Ht = 0.592 and h = 0.647 for nDNA and mtDNA, respectively) compared with protein allozymes (Ht = 0.250), estimates of the extent of population differentiation were highly concordant across marker classes (mean θ= 0.010, 0.011, and 0.016 for allozymes, nDNA, and mtDNA, respectively). Simulations of mixed-stock fisheries composed of varying contributions of U.S. and Canadian populations revealed a consistent bias for overallocation of Canadian stocks when expected Canadian contributions varied from 0 to 40%, due primarily to misallocations among genetically similar border populations. No single marker class is superior for differentiating populations of this species at the spatial scale examined.

D-region ionosphere response to the total solar eclipse of 22 July 2009 deduced from ELF-VLF tweek observations in the Indian sector

[1] Observations of tweeks with higher harmonics (n > 1) at low latitude stations Allahabad and Nainital, in the Indian sector, during the total solar eclipse on 22 July 2009, are presented. Allahabad and Nainital stations were in 100% and 85% of the totality paths. Observations suggest that about 30–40% obscuration of solar disc can lead to the tweeks occurrence which otherwise occur only in nighttime. A total of 148 tweeks at Allahabad and 20 tweeks at Nainital were recorded with some of them up to 3rd harmonics. The World Wide Lightning Location Network data indicated that tweeks observed were generated by lightning's located in the partial eclipse area of Asia-Oceania region. The changes in D-region ionospheric VLF reflection height and electron density (∼22–23 cm−3) during eclipse have been estimated from the first cut-off frequency of the tweeks. The reflection height increased from ∼89 km from the first occurrence of tweek to about 91–92 km at the totality and then decreased to ∼87 km at the end of the eclipse, suggesting a change of about 5 km in the reflection height during eclipse. The reflection heights are lower by 2–3 km as compared to normal nighttime tweek reflection heights. The above increase in the reflection height indicate that the partial nighttime condition is created during eclipse, as the main D-region ionizing radiation Lyman α is blocked but solar soft X-ray and EUV radiations originating from the limb solar corona are not totally blocked which produce some of ionization in the D-region.
Television Commercials: The Depiction and Portrayal of African-American Elderly Adults

PSI CHI JOURNAL OF UNDERGRADUATE RESEARCH Summer 2004 *Faculty Supervisor Copyright 2004 by Psi Chi, The National Honor Society in Psychology (Vol. 9, No.2, 62–67 / ISSN 1089-4136). Television (TV) program viewing is an activity that most people engage in and enjoy. In 1998, 98% of American households contained TV sets and the average time spent watching TV was 14 hours per week (Famighetti, 2000). In addition, Americans spend the majority of their leisure time watching TV rather than exploring other activities. In fact, Robinson and Skill (1993) looked at past research and found that people tend to watch more TV as they age. Specifically, elderly adults utilize TV more frequently than children, middle age and young adults because they have the most leisure time. People watch TV for entertainment purposes and to acquire information (Huston et al., 1992a). People also use TV as a means of socializing and relieving tension. According to Huston et al., the elderly depend heavily on TV because it is a source of information, recreation, mental stimulation and companionship. TV also serves as a replacement for previous occupational status, child-rearing responsibilities and domestic tasks among the elderly (Huston et al.). The types of programs that the elderly watch are different from those of middle age and young populations. The elderly enjoy watching “news, documentaries and public affairs programs” (Huston et al., p. 15). Huston et al. propose that these programs provide a “social informational network” that one often loses after employment ends (p. 15). Portrayals of people on TV are seldom representative of the individuals who actually watch the programming. Gerbner (1972) describes TV as promoting cultural values and norms and as presenting relationships among groups in society, whereas Clark (1972) proposed that groups gain recognition and respect by their portrayal on TV. Society recognizes social groups when they are visible on TV, while groups that lack representation experience non-recognition. The media gives respect to social groups when representations are positive and considerate. The disrespect of social groups results from stereotypical or negative depictions. The elderly are frequently underrepresented and are often depicted according to negative stereotypes on TV and in other forms of media. Several research studies support these findings. For example, Vasil and CHRISTI WASHINGTON
Prison education across Europe: policy, practice, politics

The nature of the education offered in prisons varies greatly. Provision can be focused narrowly on limited objectives, such as training for employment or seeking to 'address offending behaviour'. On the other hand, where prison education follows the policies of the Council of Europe or the European Union, which are drawn from the traditions of adult education and life-long learning, it becomes a more comprehensive and transformative experience for men and women held in prison. Underpinning these different approaches are two very different perceptions of those held in prison: one sees merely 'an offender', while the other recognizes 'the whole person' and his or her membership of society. Where narrow and negative concepts of the men and women held in prison prevail, one tends to find severe limitations on the quality and quantity of the education offered. Four such 'curtailments' are discussed.
Molecular characterization of Nagori cattle using microsatellite markers

The present study estimates genetic variability in nagori cattle (n=30), a draught breed of India, by use of 15 microsatellite markers recommended by the Food and Agriculture Organization. Microsatellite genotypes were derived and allelic and genotypic frequencies, heterozygosities and gene diversity were estimated. A total of 123 alleles were distinguished by the 15 microsatellite markers used. All the microsatellites were highly polymorphic, with mean (± s.e.) allelic number of 8.2±1.143, ranging 2-14 per locus. The observed heterozygosity in the population ranged between 0.52 and 0.758, with mean (± s.e.) of 0.610 ± 0.019, indicating considerable genetic variation in this population.
Multi-arm clinical trials with treatment selection: what can be gained and at what price?

With current success rates of confirmatory studies being only around 50%, new approaches to drug development are paramount. Many trials fail simply because ineffective treatments are identified too late. In this paper, we discuss the utility of multi-arm studies with treatment selection as a potential strategy that can reduce the high attrition rate. We illustrate the large gains in efficiency that are possible based on an example in Alzheimer’s disease while outlining the additional challenges that need to be overcome to implement such studies.
