Abstract We investigated the social relationships among adult females in two multimale-multifemale groups of black howler monkeys Alouatta pigra during a 14-month study in Palenque National Park, Mexico. Based on over 900 focal hours and over 5400 scan samples recording neighboring group members, we found that females very rarely engaged in agonistic interactions and no dominance hierarchy could be discerned. Relationships among resident females were primarily affiliative, but females of one study group spent a higher proportion of time in close proximity and engaged in affiliative interactions with one another at higher rates than females in the other study group. The strength of female relationships increased with the birth of an infant. Al- though no females immigrated during the study period, the temporary association of three extragroup females with our study groups implies that the social system of black howler monkeys is more dynamic than previously suggested. These findings sug- gest that female black howler monkeys behave more similarly to female red howler monkeys A. seniculus than to female mantled howler monkeys A. palliata

Sensory drive predicts coevolution of mate choice signals with the sensory systems detecting those sig nals. Guppies are a classic model for sensory drive as mate preferences based on coloration differ across individuals and populations. A large body of work has identified variation in color vision, yet we lack a dir ect tie between how such variation in color vision influences variation in color preference. Here we bring together studies that have investigated guppy vision over the past 40years to：（1） highlight our current understanding of where variation occurs in the guppy color vision pathway and （2） suggest future ave nues of research into sources of visual system variation that could influence guppy color preference. This will allow researchers to design careful studies that couple measures of color preference with measures of visual system variation from the same individual or population. Such studies will finally provide im portant answers as to what sets the direction and speed of mate preference evolution via sensory drive.

Information seekers are generally on their own to discover and use a research library’s growing array of digital col- lections, and coordination of these collections’ development and maintenance is often not optimal. The frequent lack of a con- scious design for how collections fit together is of equal concern because it means that research libraries are not making the most of the substantial investments they are making in digital initiatives. This paper proposes a framework for a research library’s digital collections that offers integrated discovery and a set of best practices to underpin collection building, federated access, and sus- tainability. The framework’s purpose is to give information seekers a powerful and easy way to search across existing and future collections and to retrieve integrated sets of results. The paper and its recommendations are based upon research undertaken by the author and a team of librarians and technologists at Cornell University Library. The team conducted structured interviews of forty-five library staff members involved in digital collection building at Cornell, studied an inventory of the library’s more than fifty digital collections, and evaluated seven existing Open Archives Initiative (OAI) and federated search production or prototype systems. The author will discuss her team’s research and the rationale for their recommendations to: present a cohesive view of the library’s digital collections for both browsing and searching at the object level; take a programmatic (rather than project-based) approach to digital collection building; require that all new digital collections conform to library-developed and agreed-upon OAI best practices for data providers; and implement organizational structures to sustain the library’s digital collections over the long term.

The British Medical Journal devoted its first issue of 2012 to the problem of unreported clinical trial data,highlighting the serious impact that incomplete information can have on world health(for an editorial summary see Lehman and Loder,2012).Adopted innovations in clinical intervention,inappro-priately based on only a subset of trial data,can,at best,prove uneconomical and,at worst,lead to large-scale patient *** its consequences may be most severe in medicine this problem applies to many scientific disciplines and we are now seeing a move towards greater transparency in data declaration.

AIM: To systematically review whether the increased fluctuation of intraocular pressure(IOP) is a risk factor for open angle glaucoma(OAG) progression. METHODS: Scientific studies relevant to IOP fluctuation and glaucoma progression were retrieved from MEDLINE,EMBASE and CENTRAL databases, and were listed as references in this paper. The hazard ratio(HR) was calculated by using fixed or random-effects models according to the heterogeneity of included studies. RESULTS: Individual data for 2211 eyes of 2637 OAG patients in fourteen prospective studies were included in this Meta-analysis. All studies were longitudinal clinical studies with follow-up period ranging from 3 to 8.5 y. The combined HR was 1.23(95%CI 1.04-1.46, P=0.02) for the association between IOP fluctuation and glaucoma onset or progression with the evidence of heterogeneity(P<0.1).Subgroup analyses with different types of IOP fluctuation were also evaluated. Results indicated that the summary HR was 0.98(95%CI 0.78-1.24) in short-term IOP fluctuation group, which showed no statistical significance with heterogeneity, whereas, the combined HR was 1.43(95%CI1.13-1.82, P=0.003) in long-term IOP fluctuation group without homogeneity. Sensitivity analysis further showed that the pooled HR was 1.10(95%CI 1.03-1.18, P=0.004) for long-term IOP fluctuation and visual function progression with homogeneity among studies(P=0.3). CONCLUSION: Long-term IOP fluctuation can be a risk factor for glaucoma progression based on the presentedevidence. Thus, controlling the swing of IOP is crucial for glaucoma or glaucoma suspecting patients.
