Compensatory Feeding and Growth Responses of \u3ci\u3ePapilio Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) Larvae Reared in Darkness.

The goal was to determine the potential impact of photoperiod on feeding behavior and larval growth rates. Larvae from six different families of the eastern swallowtail butterfly, Papilio glaucus L. (Lepidoptera: Papilionidae) were placed into 3 different photoperiod regimes (long days at 18:6 h, short days at 12:12 h, and total darkness at 0:24 h, all at 27°C) as neonate first instars and reared to pupation. The initial 11 days reflected very slow growth of the larvae in darkness (only half the weight of the long day larvae). No differences in survival at 4 days or 11 days or until pupation were evident between any treatments. Average time to pupation ( = total larval duration) was statistically identical between the treatments. However, despite their slow start during the first two instars, the larvae in complete darkness were able to increase their growth rates in the final 3 instars to such magnitude that they grew to the same final pupal size as those in the long day (and bigger than those in the short day) treatments. Such compensatory feeding and growth as a result of photoperiod has not previously been reported. Potential additional causes for such behavioral/physiological compensatory growth rates in caterpillars of other species are discussed

Measuring total employment: are a few million workers important?

How can we measure total employment in the economy? The Bureau of Labor Statistics provides two different-and sometimes contradictory-measures of this key indicator. During the 1990s, the gap between the two measures has widened to more than five million workers. This Economic Commentary examines the current discrepancy between the two measures of employment and explores its significance in interpreting our economy's health.Employment (Economic theory) ; Economic indicators

Hacking the social life of Big Data

This paper builds on the Our Data Ourselves research project, which examined ways of understanding and reclaiming the data that young people produce on smartphone devices. Here we explore the growing usage and centrality of mobiles in the lives of young people, questioning what data-making possibilities exist if users can either uncover and/or capture what data controllers such as Facebook monetize and share about themselves with third-parties. We outline the MobileMiner, an app we created to consider how gaining access to one’s own data not only augments the agency of the individual but of the collective user. Finally, we discuss the data making that transpired during our hackathon. Such interventions in the enclosed processes of datafication are meant as a preliminary investigation into the possibilities that arise when young people are given back the data which they are normally structurally precluded from accessing

Partnership and the Politics of Care: Advocates' Role in Passing and Implementing California's Law to Extend Foster Care

This report traces the history of the California's Fostering Connections to Success Act legislation from its introduction in the California State Assembly, through its passage and signing, and ultimately to its innovative and extensive implementation planning process. The report aims to document the California experience, highlighting its successes and challenges, so that other states may benefit, potentially smoothing the legislative and implementation processes there. Beyond telling the story of extended care, this report also focuses on two other issues. The first is the strong role played by a group of stakeholders (e.g., advocates, foundations, county administrators) in passing this bill and seeing it through implementation planning. We find that their central involvement was a result of their own desire to see the policy through to implementation, the limited capacity of state government agencies to implement such complex legislation, and the willingness of foundations to help fund implementation planning. The second is the degree to which research evidence was used in both the legislative and implementation planning phases. Our findings about use of evidence indicate that for research to be effective in shaping legislative decisions, it needs to be more timely and geared to policymakers' concerns. In particular, research on specific state-level contexts is greatly valued. For legislation that concerns sympathetic populations, testimonial or discursive evidence can be just as effective with legislators as research evidence. Moreover, in times of budgetary constraint, research evidence about cost effectiveness may be as important as research evidence about program or policy effectiveness

Mining Mobile Youth Cultures

In this short paper we discuss our work on coresearch devices with a young coder community, which help investigate big social data collected by mobile phones. The development was accompanied by focus groups and interviews on privacy attitudes, and aims to explore how youth cultures are tracked in mobile phone data

Affine insertion and Pieri rules for the affine Grassmannian

We study combinatorial aspects of the Schubert calculus of the affine Grassmannian Gr associated with SL(n,C). Our main results are: 1) Pieri rules for the Schubert bases of H^*(Gr) and H_*(Gr), which expresses the product of a special Schubert class and an arbitrary Schubert class in terms of Schubert classes. 2) A new combinatorial definition for k-Schur functions, which represent the Schubert basis of H_*(Gr). 3) A combinatorial interpretation of the pairing between homology and cohomology of the affine Grassmannian. These results are obtained by interpreting the Schubert bases of Gr combinatorially as generating functions of objects we call strong and weak tableaux, which are respectively defined using the strong and weak orders on the affine symmetric group. We define a bijection called affine insertion, generalizing the Robinson-Schensted Knuth correspondence, which sends certain biwords to pairs of tableaux of the same shape, one strong and one weak. Affine insertion offers a duality between the weak and strong orders which does not seem to have been noticed previously. Our cohomology Pieri rule conjecturally extends to the affine flag manifold, and we give a series of related combinatorial conjectures.Comment: 98 page

Introduction. Understanding hate crime: research, policy and practice

In 2013, a group of scholars from Europe and North America came together to form the International Network for Hate Studies (INHS). The key aims of the network included bridging gaps between academics and policy makers/practitioners in the field, and "internationalizing" our understanding of hate crime generally. In the spring of 2014, INHS held its inaugural conference at the University of Sussex in Brighton, the United Kingdom. In this special edition of Criminal Justice Policy Review (CJPR), we bring together expanded versions of four of the keynote speeches from that conference. In distinct ways, each speaks to the key themes noted above, as this brief introduction will illustrate

Active learning and the Irish treebank

We report on our ongoing work in developing the Irish Dependency Treebank, describe the results of two Inter annotator Agreement (IAA) studies, demonstrate improvements in annotation consistency which have a knock-on effect on parsing accuracy, and present the final set of dependency labels. We then go on to investigate the extent to which active learning can play a role in treebank and parser development by comparing an active learning bootstrapping approach to a passive approach in which sentences are chosen at random for manual revision. We show that active learning outperforms passive learning, but when annotation effort is taken into account, it is not clear how much of an advantage the active learning approach has. Finally, we present results which suggest that adding automatic parses to the training data along with manually revised parses in an active learning setup does not greatly affect parsing accuracy

The WIGGUM gene is required for proper regulation of floral meristem size in Arabidopsis

The study of cell division control within developing tissues is central to understanding the processes of pattern formation. The floral meristem of angiosperms gives rise to floral organs in a particular number and pattern. Despite its critical role, little is known about how cell division is controlled in the floral meristem, and few genes involved have been identified. We describe the phenotypic effects of mutations in WIGGUM, a gene required for control of cell proliferation in the floral and apical meristem of Arabidopsis thaliana. wiggum flowers contain more organs, especially sepals and petals, than found in wild-type flowers. This organ number phenotype correlates with specific size changes in the early floral meristem, preceding organ initiation. Genetic studies suggest that WIGGUM acts on a similar process but in a separate pathway than the CLAVATA1 and CLAVATA3 genes in meristem size regulation, and reveal interactions with other genes affecting meristem structure and identity. Analysis of double mutant phenotypes also reveals a role for WIGGUM in apical meristem function. We propose that WIGGUM plays a role in restricting cell division relative to cellular differentiation in specific regions of the apical and floral meristems
