"Out of sync": The breakdown of economic sentiment cycles in the E.U.

We present empirical evidence about the properties of economic sentiment cycle synchronization for Germany, France and the UK and compare them with the `crisis' countries Italy, Spain, Portugal and Greece. Instead of using output data we prefer to focus on the economic sentiment indicator (ESI), a forward-looking, survey-based variable consistently available from 1985. The cyclical nature of the ESI allows us to analyze the presence or not of synchronicity among country pairs before and after the onset of the financial crisis. Our results show that ESI movements were mostly synchronous before 2008 but they exhibit a breakdown after 2008, with this feature being more prominent in Greece. We also find that, after the political manoeuvring of the past two years, a cycle re-integration or re-synchronization is on the way. An analysis of the evolution of the synchronicity measures indicates that they can potentially be used to identify sudden phase breaks in ESI co-movement and they can offer a signal as to when the EU economies are getting “in” or “out of sync”.

Improving the educational achievement of young people in out-of-home care

A strong link between research and practice is essential to ensure
that the best available evidence gets into the hands of child welfare
practitioners, who are faced with the daunting task of making decisions
about vulnerable children on a daily basis. In 2007, a group of
senior child welfare leaders in the province of Ontario (Canada) created
a research dissemination model that replicated the worldrenowned
UK program, Research in Practice (http://www.rip.org.
uk). Practice and Research Together (PART; www.partontario.org) is
an Ontario consortium of 45 child welfare organizations whose mandate
is to disseminate research to its member agencies, which include
85% of the local child welfare organizations in the province. Each
member pays an annual membership-fee that is based on its size
(Dill & Shera, 2011). A key factor in PART's success has been its ability
to link its program offerings (i.e., webinars, literature reviews, conferences,
and publications) to issues of real-world relevance to child
welfare practitioners and senior leaders. A central and highly anticipated
program offering is PART's annual conference (learning
event). These conferences bring evidence to bear on practice in priority
areas in child welfare.
On May 31 and June 1 and 2, 2011, PART, in collaboration with the
Centre for Research on Educational and Community Services (CRECS)
at the University of Ottawa, co-hosted an international conference in
Ottawa that was focused on improving the educational achievement
of young people in out-of-home care (hereafter, in care). Speakers
from five countries – Canada, USA, Germany, Sweden, and UK – presented
the results of their research at the conference. The speakers
addressed three main topic areas: the disadvantaged socio-political
status of young people in care, many of whom do not complete secondary
or post-secondary education; innovative interventions to improve
their educational outcomes; and the effectiveness of tutoring,
which is the most common educational intervention for young people
in care.

Aspasing Out Metacaspases and Caspases: Proteases of Many Trades

Execution of programmed cell death (PCD) in nonmetazoan organisms is morphologically different from apoptotic PCD in animals and lacks a number of key molecular components of apoptotic machinery, including caspases. Yet protozoan, fungal, and plant cells exhibit caspase-like proteolytic activities, which increase in a PCD-dependent manner. This poses a question whether nonmetazoan organisms contain structurally dissimilar proteases that functionally substitute for caspases. Putative ancestors of caspases, metacaspases, are candidates for this role; however, their distinct substrate specificity raises doubts. The identification of a common biological target of caspases and metacaspases and previously unknown functions unrelated to cell death of metacaspases provide new food for thought.

Familial hypocalciuric hypercalcaemia as a differential diagnosis of hyperparathyroidism:studies in a large kindred and a review of surgical experience in the condition

We have studied 46 members of a large kindred with familial hypocalciuric hypercalcaemia (FHH) after a neck exploration failed to cure hypercalcaemia in an asymptomatic patient. Serum calcium, serum phosphate, plasma parathormone and vitamin D metabolites do not distinguish affected members from patients with hyperparathyroidism. Because of the continuing debate as to whether or not FHH is a variant of, or distinct from, hyperparathyroidism, we have carried out a review of surgical experience with subtotal parathyroidectomy in hyperparathyroidism secondary to parathyroid hyperplasia and in FHH. Whereas the procedure is successful in 90 per cent of the former cases only one case of FHH has been cured by it. This provides evidence for the two conditions being aetiologically distinct. Before patients with asymptomatic hypercalcaemia are referred for parathyroid surgery the calcium:creatinine clearance ratio should be measured using a 2 h urine sample collected after an overnight fast and a fasting blood sample. If this ratio is less than 0.01 then screening of first degree relations should be undertaken before any parathyroid surgery is performed. Unnecessary surgery can therefore be avoided.

Ranachensinin: A Novel Aliphatic Tachykinin from the Skin Secretion of the Chinese Brown Frog, Rana chensinensis

Amphibian skin secretions contain a plethora of pharmacologically-active substances and represent established sources of bioactive peptides, including tachykinins. Tachykinins are one of the most widely-studied peptide families in animals and are found in neuroendocrine tissues from the lowest vertebrates to mammals. They are characterized by the presence of a highly-conserved C-terminal pentapeptide amide sequence motif (-FXGLM-amide) that also constitutes the bioactive core of the peptide. Amidation of the C-terminal methioninyl residue appears to be mandatory in the expression of biological activity. Here, we describe the isolation, characterization and molecular cloning of a novel tachykinin named ranachensinin, from the skin secretion of the Chinese brown frog, Rana chensinensis. This peptide, DDTSDRSN QFIGLM-amide, contains the classical C-terminal pentapeptide amide motif in its primary structure and an Ile (I) residue in the variable X position. A synthetic replicate of ranachensinin, synthesized by solid-phase Fmoc chemistry, was found to contract the smooth muscle of rat urinary bladder with an EC50 of 20.46 nM. However, in contrast, it was found to be of low potency in contraction of rat ileum smooth muscle with an EC50 of 2.98 µM. These data illustrate that amphibian skin secretions continue to provide novel bioactive peptides with selective effects on functional targets in mammalian tissues.

Pull-out forces in shear connectors in composite beams with large web openings

Composite beams with large web openings are often used, and their design is controlled by Vierendeel bending at the four corners of each opening, which is assisted by local composite action with the floor slab. Development of this Vierendeel bending resistance may be limited by pull-out failure of the shear connectors. In this paper, a non-linear elasto-plastic finite element model of a composite beam with web openings was used to investigate this mode of pull-out failure. A test was performed on a typical composite slab in which the shear connectors were subject to pure tension and the failure load was 67 kN, which is approximately 70% of the longitudinal shear resistance. The results of the finite element model are compared against those obtained using the established design theory, that does not limit the vertical pull-out resistance of the shear connectors. It is shown that the local bending resistance due to composite action should be reduced when limited by pull-out of the shear connectors. A parametric study investigated the effect of openings of 600 to 1200 mm length. A simple model is developed to establish the Vierendeel bending resistance, when limited by pull-out of the shear connectors.
