Systemic Risk in the Financial System: Insights From Network Science

Analyzes systemic risk from the perspective of network structure and the connectivity links between actors. Explores how the markets' lack of robustness, the pattern of network links, and the lack of diversity in networks contributed to the crisis

Early postnatal growth of the spotted dolphin, Stenella attenuata, in the offshore Eastern Tropical Pacific.

Estimates of length at birth and early postnatal growth are made for the northern and southern populations of the offshore spotted dolphin in the offshore eastern tropical Pacific. Length at birth is estimated to be 85.4 cm for the northern population and 83.2 cm for the southern population. Analyses of series of monthly distributions of length revealed two cohorts born each year in the northern population, at least in the northern inshore part of its geographic range, but only one cohort born each year in the southern population. Growth curves fitted to the means of the monthly distributions of length gave estimates of length at 1 year of 126.2 and 132.6 cm and length at 2 years of 154.3 and 154.9 cm for the two cohorts in the northern population. and length at 1 year of 127.9 cm for the southern population. A growth curve fitted to lengths and ages (in dental growth layer groups) from the northern population gave estimates of lengths at 1 and 2 years of 123.0 and 143.0 cm, respectively

Tensor-Scalar Torsion

A theory of gravity with torsion is examined in which the torsion tensor is constructed from the exterior derivative of an antisymmetric rank two potential plus the dual of the gradient of a scalar field. Field equations for the theory are derived by demanding that the action be stationary under variations with respect to the metric, the antisymmetric potential, and the scalar field. A material action is introduced and the equations of motion are derived. The correct conservation law for rotational angular momentum plus spin is observed to hold in this theory.Comment: 10 pages, LaTeX, Mod. Phys. Lett. A accepte

Children with Foetal Alcohol Spectrum Disorder and their Experiences of School Belonging: An Interpretative Phenomenological Analysis

Background Children with Foetal Alcohol Spectrum Disorder (FASD) are considered a vulnerable population of learners. Their complex neurodevelopmental profiles and ‘invisible’ disabilities can present as challenging for educators and may curtail full and meaningful participation in school life. Despite the high numbers of children with FASD believed to be within the British education system, knowledge and understanding amongst UK professionals remains scant. What is more, there exists a dearth of research which has given pupils with FASD a voice to share their school experiences. Methods This qualitative research study explored the lived experiences of school belonging from the perspectives of four children (aged 7-10 years) with a known diagnosis of FASD. Data was collected using remote semi-structured interviews and sought to explore what helps children with FASD to belong in UK mainstream primary schools. Participants were invited to represent their views using drawing and modelling. Discrepancies between their perceived sense of school belonging and preferred sense of school belonging were explored. The data was analysed using an Interpretative Phenomenological Analysis (IPA) approach. Results All four of the children with FASD felt like they belonged in their respective schools and told of factors which facilitated their positive belongingness experiences. These were grouped into four superordinate themes: School Ethos and Sense of Community, Relatedness to Peers, Staff Attributes and Teaching Practices, and Myself as a Learner. The findings provide support for Allen et al’s. (2016) Socio-Ecological Framework of School Belonging. Conclusions It is anticipated that this research will go some way towards raising the profile of FASD amongst frontline educational professionals in the UK. Given children and young people with FASD are vulnerable to disrupted schooling, strengthening their belongingness to school may be one way in which to promote positive and inclusive school experiences and mimimise the risk of secondary disabilities

Strings in gravity with torsion

A theory of gravitation in 4D is presented with strings used in the material action in $U_4$ spacetime. It is shown that the string naturally gives rise to torsion. It is also shown that the equation of motion a string follows from the Bianchi identity, gives the identical result as the Noether conservation laws, and follows a geodesic only in the lowest order approximation. In addition, the conservation laws show that strings naturally have spin, which arises not from their motion but from their one dimensional structure.Comment: 16 page

Computed tomography and magnetic resonance diagnosis of variations in the anatomical location of the major salivary glands in 1680 dogs and 187 cats

During assessment of routine clinical magnetic resonance imaging (MRI) of the heads of dogs, variations in the location of mandibular and zygomatic salivary glands (SGs) were observed incidentally. The aims of this retrospective study were to describe anatomical variations of the major SGs found on MRI and computed tomography (CT) studies of the head in dogs and cats and to investigate possible clinical relevancy. No anatomical variation of the SGs was seen in cats, but in dogs, although variation of the parotid SG was not identified, that of the mandibular SG was found in 33/1680 animals (2%), either unilaterally (6/33 right-sided, 13/33 left-sided) or bilaterally (14/33). The Border terrier breed (19/33, 58%) was over-represented. Each atypically located mandibular SG was positioned medial to the digastric muscle and rostral to the retropharyngeal lymph node. The sublingual glands were difficult to delineate from the mandibular glands. Anatomical variation of one zygomatic gland (3/4 left-sided) was identified in four small-breed dogs (0.2%). Each atypically located zygomatic gland was tilted at the ventrorostral aspect of the masseter muscle underneath the skin surface. MRI and CT characteristics were not different between typically and atypically located SGs. None of the dogs had clinical signs related with SG disease. It was concluded that, with suspected breed predispositions, incidental unilateral or bilateral anatomical variations of mandibular and zygomatic SGs can be encountered in dogs and an awareness of these possible variations may be important in pre-surgical planning

The AFGL absolute gravity program

A brief discussion of the AFGL's (Air Force Geophysics Laboratory) program in absolute gravity is presented. Support of outside work and in-house studies relating to gravity instrumentation are discussed. A description of the current transportable system is included and the latest results are presented. These results show good agreement with measurements at the AFGL site by an Italian system. The accuracy obtained by the transportable apparatus is better than 0.1 microns sq sec 10 microgal and agreement with previous measurements is within the combined uncertainties of the measurements

Migration with local public goods and the gains from changing places

Without public goods and under fairly standard assumptions, in Hammond and Sempere (J Pub Econ Theory, 8: 145–170, 2006) we show that freeing migration enhances the potential Pareto gains from free trade. Here, we present a generalization allowing local public goods subject to congestion. Unlike the standard literature on fiscal externalities, our result relies on fixing both local public goods and congestion levels at their status quo values. This allows constrained efficient and potentially Pareto improving population exchanges regulated only through appropriate residence charges, which can be regarded as Pigouvian congestion taxes
