Selective Migration and Health
We investigate the proposition that the health of migrants does not constitute a random sample of the health of the sending region using data from the Panel Study of Income Dynamics on internal migration within the United States. Panel data is crucial, as it enables us to observe geographic mobility as well as the health of the migrant prior to migration. We find that, for men and women below 60 years of age, a move from the middle to the bottom of the health distribution reduces mobility by 32-40% and 12-18%, respectively. Nonrandom attrition from the panel implies that these estimates are lower bounds. By contrast, we find evidence that, among older people, there is higher mobility at the top and bottom of the health distribution than there is at the middle. We consider two explanations for this: first that elderly persons may migrate to be closer to a family network once they fall ill, and second that non-random attrition may also be causing an upwards bias in the estimated effect of illness on mobility.Migration, Health, Selection, Attrition
Finite temperature phase transition, adjoint Polyakov loop and topology in SU(2) LGT
We investigate the phase structure of pure SU(2) LGT at finite temperature in
the mixed fundamental and adjoint representation modified with a Z2 monopole
chemical potential. The decoupling of the finite temperature phase transition
from unphysical zero temperature bulk phase transitions is analyzed with
special emphasis on the continuum limit. The possible relation of the adjoint
Polyakov loop to an order parameter for the finite temperature phase transition
and to the topological structure of the theory is discussed.Comment: 3 pages, 3 figures LaTeX file. Uses espcrc2 style and amssymb

The Roman army in Syria, Judaea and Arabia
I have attempted to answer three questions in this thesis. Firstly, what was the identity of the garrisons of Syria, Judaea and Arabia from the reign of Augustus to the end of the fourth century? Secondly, what were the dispositions of these troops and the implications of these dispositions? In the first two chapters I discuss the evidence for the units in garrison in Syria and trace their changing role as Syria was pacified and Roman power expanded eastwards, gradually but relentlessly until the mid-third century, recovering under Diocletian but relapsing into a defensive posture by c. AD 400. ‘In chapters four, five and seven I examine the best-attested armies of the client-kings who ruled Judaea and its environs and those of the Roman provinces of Judaea, later Syria-Palaestine, and Arabia and trace their changing role from armies of pacification to forces of frontier defence.
I have thirdly, in chapters three, six and eight, examined recruitment to the auxilia of the provincial armies during the same period. Most commanders in Syria under the Julio-Claudian emperors came from Italy or Augustan colonies. By the later first century they are coming from the more civilised provinces of the empire and by the third century from Syria itself. Our slight evidence for Judaea and Arabia suggests similar trends, with evidence for local commanders in Arabia in the fourth century. A not inconsiderable proportion of the soldiers these officers commanded were during the early first century drawn from the west and, despite increasing local recruitment, recruits from outside Syria continued to be sent during the second century. Severus recruited on a vast scale from the east but local forces continued in the fourth century to be supplemented by units from the west.
In my concluding chapter nine I outline the development of the frontier in the light of my work and present my findings on recruitment against the background of evidence for legionary recruitment in the east and for auxiliary recruitment in the rest of the empire
Terra incognita—cerebellar contributions to neuropsychiatric and cognitive dysfunction in behavioral variant frontotemporal dementia
Although converging evidence has positioned the human cerebellum as an important relay for intact cognitive and neuropsychiatric processing, changes in this large structure remain mostly overlooked in behavioral variant frontotemporal dementia (bvFTD), a disease which is characterized by cognitive and neuropsychiatric deficits. The present study assessed whether degeneration in specific cerebellar subregions associate with indices of cognition and neuropsychiatric performance in bvFTD. Our results demonstrate a relationship between cognitive and neuropsychiatric decline across various domains of memory, language, emotion, executive, visuospatial function, and motivation and the degree of gray matter degeneration in cerebellar lobules V–VII. Most notably, bilateral cerebellar lobule VII and the posterior vermis emerged as distinct for memory processes, the right cerebellar hemisphere underpinned emotion, and the posterior vermis was highlighted in language dysfunction in bvFTD. Based on cortico-cerebellar connectivity maps, these findings in the cerebellum are consistent with the neural connections with the cortices involved in these domains in patients with bvFTD. Overall, the present study underscores the significance of cortical-cerebellar networks associated with cognition and neuropsychiatric dysfunction in bvFTD
Global surveillance of dirty money: assessing assessments of regimes to control money-laundering and combat the financing of terrorism
Anti-money laundering: an inquiry into a disciplinary transnational legal order
This Article enquires into the case of one of the most comprehensive,
far-reaching, most deeply penetrating, and most punitive of TLOs: antimoney
laundering. Drawing on an intensive study at a moment when its
governing norms and methodologies of implementation were undergoing
revision and expansion, as well as on observation and participation in
AML/CFT activities over three decades, the Article brings rich empirical
evidence to bear on two theoretical issues. First, despite its seemingly
successful institutionalization, the AML TLO exhibits many deficiencies
and imposes extensive costs on the private and public sectors, and harms
upon the public. Why doesn’t it fail? Second, the pervasiveness and
penetration of the AML TLO indicates it may constitute a particular
species of “disciplinary” TLOs. To address these issues, the Article, first,
briefly sketches the thirty-year development and workings of the AML
TLO; second, considers its benefits, costs, deficiencies and harms; third,
confronts the puzzle of its persistence; and, fourth, concludes by arguing that
the AML TLO may be distinctive insofar as (1) it has a foundational
assumption of recalcitrant actors who must be monitored to reduce social
harms which (2) legitimates a pervasive surveillance apparatus that is (3)
yoked to punitive criminal institutions and practices which (4) lead to an
elaborate repertoire of discipline that (5) has been multiplied to include
states, financial institutions (e.g. banks), non-state collective actors such as
charities, organized crime families, and individuals such as lawyers,
accountants, and everyday participants in their myriads of transactions in
an integrated global financial system. Those singular properties may in fact
be shared substantially by other TLOs directed at crime. The site of criminal
justice thereby encourages a more differentiated understanding of TLOs in
21st century settings
Abnormal connectivity between the default mode and the visual system underlies the manifestation of visual hallucinations in Parkinson’s disease:A task-based fMRI study
Background: The neural substrates of visual hallucinations remain an enigma, due primarily to the difficulties associated with directly interrogating the brain during hallucinatory episodes. Aims: To delineate the functional patterns of brain network activity and connectivity underlying visual hallucinations in Parkinson’s disease. Methods: In this study, we combined functional magnetic resonance imaging (MRI) with a behavioral task capable of eliciting visual misperceptions, a confirmed surrogate for visual hallucinations, in 35 patients with idiopathic Parkinson’s disease. We then applied an independent component analysis to extract time series information for large-scale neuronal networks that have been previously implicated in the pathophysiology of visual hallucinations. These data were subjected to a task-based functional connectivity analysis, thus providing the first objective description of the neural activity and connectivity during visual hallucinations in patients with Parkinson’s disease. Results: Correct performance of the task was associated with increased activity in primary visual regions; however, during visual misperceptions, this same visual network became actively coupled with the default mode network (DMN). Further, the frequency of misperception errors on the task was positively correlated with the strength of connectivity between these two systems, as well as with decreased activity in the dorsal attention network (DAN), and with impaired connectivity between the DAN and the DMNs, and ventral attention networks. Finally, each of the network abnormalities identified in our analysis were significantly correlated with two independent clinical measures of hallucination severity. Conclusions: Together, these results provide evidence that visual hallucinations are due to increased engagement of the DMN with the primary visual system, and emphasize the role of dysfunctional engagement of attentional networks in the pathophysiology of hallucinations

Three dimensions of maturity required to achieve future state, technology-enabled manufacturing supply chains
The particular challenges associated with supply chain application of emerging manufacturing technologies are increasingly recognised in industry, academia and government. The problem is often described in terms of Technology Readiness Levels (TRLs), with the particular challenge relating to the stages between proof of concept and initial adoption in the factory environment. In the UK the government has established the High Value Manufacturing Catapult, a network of manufacturing innovation centres brought together with the objective of addressing the so called ‘valley of death’ between traditional academic research and industrial needs across a broad spectrum of manufacturing process technology. This is achieved through demonstrating manufacturing technology at full scale, in factory representative environments in terms of equipment, process control and operation. This provision helps to address the key gap of full scale pre-production capability demonstration and can be seen to de-risk investment in new manufacturing technology. This paper argues that addressing this particular gap is entirely necessary but not sufficient to drive exploitation of the full potential that is available from the latest manufacturing technologies. A three dimensional maturity based framework is proposed which, in addition to considerations of technology demonstration, also allows the position of the target product application in its product lifecycle, and the readiness of the supply chain to receive the technology to be taken into account as success factors in the potential for industrialisation. Case study examples, both current and historical, are used to illustrate the need for such an approach in achieving future technology enabled supply chains. In combination this analysis introduces the basis of a more complete ‘long valley of death’ description which articulates the needs of research networks to establish a level of foundational capability ahead of specific client readiness projects in order to maximise overall pace and achieve a level of agility of delivery which is consistent with future views on digitalisation of manufacture
