Restrictions on Aliens in the United Kingdom, 1914-1919 : a Study of the Origins and Political Background of the Aliens Restrictions Acts of 1914 and 1919.

At first glance the Aliens Restriction Act of 1914, which was introduced and passed on the first day of World War One, seems a hasty and ill-prepared piece of legislation. Actually, when examined in the light of Arthur Marwick's thesis that war is a forcing house for pre-existent social and governmental ideas, it becomes clear that the act was not after all the product of hastily formed notions. In point of fact it followed the precedent of detailed draft clauses produced in 1911 by a sub-committee of the Committee of Imperial Defence established to consider the treatment of aliens in the event of war. Indeed the draft clauses and the restrictions embodied in the 1914 act were strikingly similar to restrictions on aliens legislated in 1793. Hostility to aliens had been growing from 1905 to 1914 and this hostility blossomed into xeno-phobia on the outbreak of war, a crucial precondition for the specifically anti-enemy fears of the time. In 1919 the Aliens Restriction (Amendment) Bill was introduced into parliament to extend temporarily the provisions of the 1914 act thus permitting the Home Secretary to plan permanent, detailed legislation. Two minority groups of MPs with extreme views on the treatment of aliens were prominent in the debates on this bill. The extreme Liberal group which advocated leniency in the treatment of aliens had little effect on the final form of the bill, but the extreme Conservative group, which demanded severe restrictions on aliens, succeeded in persuading the government to include detailed restrictions. Despite its allegedly temporary nature, the Aliens Restriction (Amendment) Act of 1919 was renewed annually until 1971.

British Balance of Competence Reviews, Part I: ‘Competences about right, so far’. EPIN Working Paper No. 35, October 2013

The first in a series for a CEPS-EPIN project entitled “The British Question and the Search for a Fresh European Narrative” this paper is pegged on an ambitious ongoing exercise by the British government to review all the competences of the European Union. The intention is that this should provide a basis for informed debate before the referendum on the UK remaining in the EU or not, which is scheduled for 2017. This paper summarises the first six reviews, each of which runs to around 80 pages, covering foreign policy, development policy, taxation, the single market, food safety, and public health. The present authors then add their own assessments of these materials. While understandably giving due place to British interests, they are of general European relevance. The substantive conclusions of this first set of reviews are that the competences of the EU are judged by respondents to be ‘about right’ on the whole, which came as a surprise to eurosceptic MPs and the tabloid media. Our own view is that the reviews are objective and impressively researched, and these populist complaints are illustrating the huge gap between the views of informed stakeholders and general public opinion, and therefore also the hazard of subjecting the ‘in or out’ choice for decision by referendum. If the referendum is to endorse the UK’s continuing membership there will have to emerge some fresh popular narratives about the EU. The paper therefore concludes with some thoughts along these lines, both for the UK and the EU as a whole.

The Italian Parliament and the EU: a slow and gradual Europeanization. ACES Working Papers, August 2009

In this paper we discussed how the literature traces a growing involvement of the national parliaments in EU policy-making. Three phases can be distinguished: limited or no involvement was the trend until the 1980s; after the Single Act (SEA, 1987), national parliaments started to be interested in European affairs and to set up specialized committees; following the Maastricht Treaty (TUE, 1992), the involvement of national parliaments in EU affairs became a response to the question of "democratic deficit" in the EU (Norton, 1995). The growing number of policies dealt with at the EU level, the consequently increased influence of EU law in national legislations, the new powers of the Union: all of these worked together to push national legislators to seek a scrutiny role in the drafting of EU legislation. According to Laprat (1995: 1), once the TUE was formally approved, a more parliamentary climate prevailed. In more recent years, national parliaments have distinguished themselves for their increased role in the scrutiny of EU legislation (Raunio and Hix, 200I: !52); more specialized MPs sit in the committees on EU affairs; the amount of work for EU specialists has increased. Also, parliamentary scrutiny, initially only optional and ex post, is now increasingly ex ante and/or mandatory (Maurer and Wessels, 2001: 425-475).

Shallow vs. Deep Integration in the Southern Mediterranean: Scenarios for the region up to 2030. MEDPRO Technical Report No. 13/March 2012

This research develops a quantitative analysis aimed at simulating the trade effects of various integration scenarios between the EU and its Mediterranean Partners (MPs). Results for shallow integration show that the completion of tariff removal is expected to produce limited gains, except in Algeria. However, further steps toward deep integration would lead to much more significant gains. In this regard, the elimination of non-tariff barriers is expected to increase EU exports to MPs up to 60%. In addition, MPs’ imports and exports to the EU could also considerably increase due to an improvement of logistics performance in these countries.

How European Integration Impacts on National Legislatures: The Europeanization of The German Bundestag. CES Germany and Europe Working Papers, No. 06.2, 2006

In looking at the Europeanization of the German Bundestag, the paper brings together two different debates: the well-established debate on the democratic legitimacy of the European Union sees national Parliaments as guarantor of one branch of a "dual" legitimacy. The more recent debate on "Europeanization" addresses the impacts that European integration has had on its Member States. Analyzing the Europeanization of the German Bundestag, the paper identifies and analyzes three dimensions: legislative Europeanization – the extent to which legislative decision making by the German Bundestag has been influenced by European stipulations over the last twenty years; institutional Europeanization – how the Bundestag as an institution reacted to this loss of function by establishing institutional and procedural provisions for influencing the government's Euro-politics; and strategic Europeanization – the ways in which individual MPs started more recently to develop euro-political strategies that go beyond controlling the national government. The paper shows that the Bundestag only hesitantly reacted to the increasing loss of functions through legislative Europeanization by establishing effective institutional and procedural provisions for controlling the government's Euro-political activities. What is more, the establishment of institutions does not guarantee their effective use. All in all, Euro- politics continues to remain the activity of few MPs. These few, however, have more recently started to europeanize their strategies. The empirical findings support the claim that the traditional concept of chains of legitimacy is inadequate, both in conceptual and in empirical terms. With regard to the democ- ratic legitimacy of EU governance, this indicates that, apart from major reform projects, especially with regard to everyday legislation, not too great a burden should be placed on national Parliaments.

Cameron’s ‘renegotiations’ (or Russian roulette) with the EU: An interim assessment. CEPS Working Document No. 413/September 2015

Since the May 2015 general election when the Tory Party gained an absolute majority in the House of Commons, Prime Minister Cameron has put his campaign into high gear to get a ‘new settlement’ with the EU and invested much personal diplomacy to try to advance his objective. “What does he really want?” is still heard from other EU leaders, yet his agenda is taking rough shape with calls for results under four headings: “competitiveness, sovereignty, social security and economic governance”. These are only code words, however, for a mixed bag of more specific desiderata, which overall seem to be moderate. Impossible demands have been quietly dropped. Some items will still be tricky to negotiate while others can be placed on the agenda for ongoing EU ‘reform’ that can be widely supported. The Brussels side of the affair thus seems manageable, but the wild cards at home in the UK remain or are becoming even wilder. The standard hazards of the referendum instrument are now exacerbated by the unknown quantity of the new Labour leadership alongside the aggressively Eurosceptic majority of Tory MPs and the great migration crisis, which is translating now into a negative factor for the EU in UK opinion polls. This ostensibly very democratic process is looking more and more like a deadly serious game of Russian roulette.

Characterization of histopathological lesions in a biological model for environmental studies: Eisenia andrei Bouché. Preliminar results

Introduction The strong expansion of the world production of plastics caused a severe accumulation of plastic debris in the environment, which makes them one of the most important contaminants, growing as a global environmental problem. Although the production in Europe has been relatively constant in the last 10 years, world plastic production continues to increase, affecting soil biota and their functions. Objectives Thus, in order to evaluate the effects of MP in soil-dwelling organisms, earthworms (Eisenia andrei Bouché), were exposed to standard artificial soil mixed with MPs and the authors documented, using microscopic figures, the pathological lesions found in this biological model. Material and Methods Eight adult earthworms extracted from soils contaminated with different concentrations of MP (mg/kgdw) with sizes ranging between 250-1000 m, were fixed in 10% neutral-buffered formalin and processed for routine histopathological diagnosis. Results and discussion Contrary to what would be expected, MP were not found throughout the GI tube of earthworms but several lesions were found in the individuals extracted from the soils with high MP concentrations, when compared with control group, namely epithelial intestinal atrophy and evidences of inflammatory responses to this stress agent. Conclusion Earthworms have probably avoided the consumption of the biggest MPs. However, evidences point for lesions that were likely caused by the smallest MPs that were likely egested during the depuration phase.

Maternal separation followed by isolation-housing differentially affects prepulse inhibition of the acoustic startle response in C57BL/6 mice

Exposure to chronic stress is associated with an increased incidence of neuropsychiatric dysfunction. The current study evaluated two competing hypotheses, the cumulative stress and the match/mismatch hypothesis of neuropsychiatric dysfunction, using two paradigms relating to exposure to “stress”: pre-weaning maternal separation and post-weaning isolation-housing. C57BL/6 offspring were reared under four conditions: typical animal facility rearing (AFR, control), early handling (EH, daily 15 min separation from dam), maternal separation (MS, daily 4 hr separation from dam), and maternal and peer separation (MPS, daily 4 hr separation from dam and from littermates). After weaning, mice were either housed socially (2–3/cage) or in isolation (1/cage) and then tested for prepulse inhibition in adulthood. Isolation-housed MPS subjects displayed greater deficits in prepulse inhibition relative to socially-housed MPS subjects while socially-housed AFR subjects displayed greater deficits in prepulse inhibition relative to isolation-housed AFR subjects. The results indicate that these treatment conditions represent a potentially valuable model for evaluating the match/mismatch hypothesis in regards to neuropsychiatric dysfunction.

Apoptotic cell removal in development and tissue homeostasis

Cell deletion is a physiological process for the development and maintenance of tissue homeostasis in metazoa. This is mainly achieved by the induction of various forms of programmed cell death followed by the recognition and removal of the targeted cells by phagocytes. In this review, we will discuss cell deletion in relation to the development and function of the innate immune system, particularly of the mononuclear phagocyte system (MPS), its ontogeny and potential role in tissue remodeling in the embryo and adult. Ongoing studies are addressing the roles of professional phagocytes of the MPS and neighboring tissue cells in dying cell removal, and candidate molecules that might attract mononuclear phagocytes to the dying cells. The potential phagocyte must discriminate between living and dying cells; current concepts for this discrimination derive from the observation of newly exposed ligands on the dying cells and new evidence for direct inhibition of uptake by viable cells.

The mononuclear phagocyte system

The mononuclear phagocyte system (MPS) has been defined as a family of cells comprising bone marrow progenitors, blood monocytes and tissue macrophages. Macrophages are a major cell population in most of the tissues in the body, and their numbers increase further in inflammation, wounding and malignancy. Their trophic roles for other cell types in development and homeostasis are becoming increasingly evident. The receptor for macrophage colony-stimulating factor (CSF-1R) is expressed in a large proportion of cells considered to be mononuclear phagocytes, including antigen-presenting dendritic cells, which can be considered a specialized adaptive state rather than a separate lineage. The unity of the MPS is challenged by evidence that there is a separate embryonic phagocyte lineage, by the transdifferentiation and fusion of MPS cells with other cell types, and by evidence of local renewal of tissue macrophage populations as opposed to monocyte recruitment. The concept of the MPS may have partly outlived its usefulness.

New investigations into macular pigment optical density

Macular pigment (MP) is the collective name for three carotenoids, lutein, zeaxanthin and meso-zeaxanthin, which are found at high concentrations in the central macula. The macular carotenoids, like all carotenoids, are entirely of dietary origin. The term ‘macular pigment optical density’ (MPOD) refers to the peak concentration of MP in the retina, which varies from one individual to the next and is measurable in vivo. On account of its blue-light-filtering and antioxidant properties, MP has become a subject of interest with respect to age-related macular degeneration (AMD), the hypothesis being that MP helps to protect against AMD; the higher the MPOD, the lower the risk for AMD. Recently, a new MPOD-measuring device, the MPS 9000 (MPS), entered the ophthalmic market. Using this device, the research described here aimed to contribute new information to the MP literature. A second MPOD instrument, the Macular Pigment Reflectometer, was also used at times, but a reliability study (included in the thesis) demonstrated that it was unsuitable for use on its own. First, a series of exploratory investigations were undertaken to maximize the accuracy and consistency of MPOD measurements taken with the MPS; a protocol was established that substantially improved repeatability. Subsequently, a series of MPOD-based studies were conducted on anisometropia, South Asian race, blue-light-filtering contact lenses, and dietary modification with kale. The principle findings were as follows: interocular MPOD differences were not attributable to interocular refractive error differences; young adults of South Asian origin had significant gender-related MPOD differences (males>females, p<0.01), and they also had significantly higher MPOD than Caucasians (p<0.0005); wearing blue-light-filtering contact lenses for eight months did not affect MPOD; and dietary modification with kale for 16 weeks did not increase MPOD. This body of research adds new insights to MP knowledge, which in turn may contribute to MP knowledge in the context of AMD.

Computerised control of cellular manufacturing systems

This thesis reviews the existing manufacturing control techniques and identifies their practical drawbacks when applied in a high variety, low and medium volume environment. It advocates that the significant drawbacks inherent in such systems, could impair their applications under such manufacturing environment. The key weaknesses identified in the system were: capacity insensitive nature of Material Requirements Planning (MRP); the centralised approach to planning and control applied in Manufacturing Resources Planning (MRP IT); the fact that Kanban can only be used in repetitive environments; Optimised Productivity Techniques's (OPT) inability to deal with transient bottlenecks, etc. On the other hand, cellular systems offer advantages in simplifying the control problems of manufacturing and the thesis reviews systems designed for cellular manufacturing including Distributed Manufacturing Resources Planning (DMRP) and Flexible Manufacturing System (FMS) controllers. It advocates that a newly developed cellular manufacturing control methodology, which is fully automatic, capacity sensitive and responsive, has the potential to resolve the core manufacturing control problems discussed above. It's development is envisaged within the framework of a DMRP environment, in which each cell is provided with its own MRP II system and decision making capability. It is a cellular based closed loop control system, which revolves on single level Bill-Of-Materials (BOM) structure and hence provides better linkage between shop level scheduling activities and relevant entries in the MPS. This provides a better prospect of undertaking rapid response to changes in the status of manufacturing resources and incoming enquiries. Moreover, it also permits automatic evaluation of capacity and due date constraints and hence facilitates the automation of MPS within such system. A prototype cellular manufacturing control model, was developed to demonstrate the underlying principles and operational logic of the cellular manufacturing control methodology, based on the above concept. This was shown to offer significant advantages from the prospective of operational planning and control. Results of relevant tests proved that the model is capable of producing reasonable due date and undertake automation of MPS. The overall performance of the model proved satisfactory and acceptable.

The effect of care solutions on the bulk and surface properties of soft contact lenses

Purpose: Soft contact lenses for continuous wear require the use of cleaning regimes which utilise hydrogen peroxide systems or multipurpose cleaning solutions (MPS). The compositions of MPS are becoming increasingly complex and often include disinfectants, cleaning agents, preservatives, wetting agents, demulcents, chelating and buffering agents. Recent research on solution–lens interactions has focused on specific ocular parameters such as corneal staining. However the effect of a solution on the lens, particularly silicone hydrogel lenses, itself has received less attention. The purpose of this work was to establish and understand the effects that care solutions have on selected bulk and surface material properties. Methods: Selected bulk and surface properties of each material (etafilcon A, vifilcon A, balafilcon A, senofilcon A, lotrafilcon A and lotrafilcon B, galyfilcon A) were measured after a 24 h soak in a variety of care solutions. Additionally the lenses were soaked for 24 h in hyperosmolar (680 mOsm L-1) and hyposmolar (170 mOsm L-1) PBS. A bulk property parameter the total diameter (TD) was measured using an Optimec contact lens analyser. The surface property related CoF of soaked lenses was measured on a nano-tribometer with conditions of load 30 mN, at a distance of 20 mm and speed 30 mm/min. Results: In terms of bulk properties, change is related to the EWC of the lens, the higher the EWC of the lens the greater the TD changes. Silicone hydrogel lenses have EWCs of <47% and little or no TD changes were observed; lotrafilcon A exhibited no change irrespective of the cleaning solution. Conventional contact lenses have higher EWCs (58% for etafilcon A and 55% for vifilcon A) and the TD was seen to change to a greater extent, for example the etafilcon A material in ReNu MPS had an increase to 14.45± 0.07 mm from the cited 14.2 mm. Other lenses increased or decreased in TD depending on the solution used. The osmolarity of the solution although important is not the only factor governing change in the TD, for example soaking senofilcon A in hyperosmolar PBS (680 mOsm L-1) for 24 h increased the TD of the lens (+0.25 ± 0.07 mm), however when the same lens type was soaked for 24 h in a MPS with a lower osmolarity there was a similar effect. Biotribology measurements demonstrated that some solution–lens combinations can reduce the CoF by 55%, when compared with biotribology with the native packing solution. An increase in the CoF was observed for other solution–lens combinations. Conclusions: There is a dramatic difference in bulk and surface performance of specific lens materials with particular care solutions. Individual components of the care solutions have effects on the bulk and surface properties of contact lenses. The affects are not as great with the silicone hydrogel as compared with conventional hydrogels.

Improving the repeatability of heterochromatic flicker photometry for measurement of macular pigment optical density

Background: Heterochromatic flicker photometry (HFP) is a psychophysical technique used to measure macular pigment optical density (MPOD). We used the MPS 9000 (MPS) HFP device. Our aim was to determine if the repeatability of the MPS could be improved to make it more suitable for monitoring MPOD over time. Methods: Intra-session repeatability was assessed in 25 participants (aged 20-50 years). The resulting data was explored in detail, e.g., by examining the effect of removal and adjustment of data with less than optimal quality parameters. A protocol was developed for improved overall reliability, which was then tested in terms of inter-session repeatability in a separate group of 27 participants (aged 19-52 years). Results: Removal and adjustment of data reduced the intra-session coefficient of repeatability (CR) by 0.04, on average, and the mean individual standard deviation by 0.004. Raw data observation offered further insight into ways of improving repeatability. The proposed protocol resulted in an inter-session CR of 0.08. Conclusions: Removal and adjustment of less than optimal data improved repeatability, and is therefore recommended. To further improve repeatability, in brief we propose that each patient perform each part of the test twice, and a third time where necessary (described in detail by the protocol). Doing so will make the MPS more useful in research and clinical settings. © 2012 Springer-Verlag.

Acute mobile phone operation affects neural function in humans

OBJECTIVES: Mobile phones (MP) are used extensively and yet little is known about the effects they may have on human physiology. There have been conflicting reports regarding the relation between MP use and the electroencephalogram (EEG). The present study suggests that this conflict may be due to methodological differences such as exposure durations, and tests whether exposure to an active MP affects EEG as a function of time. METHODS: Twenty-four subjects participated in a single-blind fully counterbalanced cross-over design, where both resting EEG and phase-locked neural responses to auditory stimuli were measured while a MP was either operating or turned off. RESULTS: MP exposure altered resting EEG, decreasing 1-4 Hz activity (right hemisphere sites), and increasing 8-12 Hz activity as a function of exposure duration (midline posterior sites). MP exposure also altered early phase-locked neural responses, attenuating the normal response decrement over time in the 4-8 Hz band, decreasing the response in the 1230 Hz band globally and as a function of time, and increasing midline frontal and lateral posterior responses in the 30-45 Hz band. CONCLUSIONS: Active MPs affect neural function in humans and do so as a function of exposure duration. The temporal nature of this effect may contribute to the lack of consistent results reported in the literature.
