Illegality Regimes and the Ongoing Transformation of Contemporary Citizenship
This article introduces the notion of âillegality regimesâ and argues that the creation, enhancement, and strengthening of these regimes has a transformative, and perhaps even corrosive effect on the meaning and value of citizenship itself. The notion of illegality regimes refers to the complex normative and policy framework that is either intended to, or otherwise has the effect of marginalizing or otherwise excluding irregular migrants, and to assist the authorities in the process of localizing and deporting them. Much of the political and scholarly attention in the context of illegality is focused on how illegality regimes affect migrants and refugees, how these regimes weaken their human rights, and generally run contrary to liberal principles such as equality before the law and non-discrimination. However, the objective here is to explore how it is not just the undocumented migrant that is directly or indirectly affected by the illegality regimes, but also regular migrants, asylum seekers, and finally full citizens themselves. The ways in which this happens is by a progressive transformation of what it means to be a citizen, and by means of a re-accommodation of the relation between the citizen and the state. As globalization unleashes migratory processes, the state adapts. Citizenship adapts along
On the computation of BernsteinâSato ideals
AbstractIn this paper we compare the approach of Briançon and Maisonobe for computing BernsteinâSato idealsâbased on computations in a PoincarĂ©âBirkhoffâWitt algebraâwith the readily available method of Oaku and Takayama. We show that it can deal with interesting examples that have proved intractable so far
A novel programmable lysozyme-based lysis system in Pseudomonas putida for biopolymer production
IndexaciĂłn: Scopus; Web of Science.Cell lysis is crucial for the microbial production of industrial fatty acids, proteins, biofuels, and biopolymers. In this work, we developed a novel programmable lysis system based on the heterologous expression of lysozyme. The inducible lytic system was tested in two Gram-negative bacterial strains, namely Escherichia coli and Pseudomonas putida KT2440. Before induction, the lytic system did not significantly arrest essential physiological parameters in the recombinant E. coli (ECPi) and P. putida (JBOi) strain such as specific growth rate and biomass yield under standard growth conditions. A different scenario was observed in the recombinant JBOi strain when subjected to PHA-producing conditions, where biomass production was reduced by 25% but the mcl-PHA content was maintained at about 30% of the cell dry weight. Importantly, the genetic construct worked well under PHA-producing conditions (nitrogen-limiting phase), where more than 95% of the cell population presented membrane disruption 16 h post induction, with 75% of the total synthesized biopolymer recovered at the end of the fermentation period. In conclusion, this new lysis system circumvents traditional, costly mechanical and enzymatic cell-disrupting procedures.https://www.nature.com/articles/s41598-017-04741-2.pd
Disruption Management in Airline Operations Control â An Intelligent Agent-Based Approach
Operations control is one of the most important areas for an airline company. Through operations control mechanisms an airline company monitors all the flights checking if they follow the schedule that was previously defined by other areas of the company. Unfortunately, some problems may arise during this stage (Clausen et al., 2005). Those problems can be related with crewmembers, aircrafts and passengers. The Airline Operations Control Centre (AOCC) includes teams of experts specialized in solving the above problems under the supervision of an operation control manager. Each team has a specific goal contributing to the common and general goal of having the airline operation running under as few problems as possible. The process of solving these kinds of problems is known as Disruption Management (Kohl et al., 2004) or Operations Recovery
Tritium clouds environmental impact in air into the Western Mediterranean Basin evaluation
The paper considers short-term releases of tritium (mainly but not only tritium hydride (HT)) to the atmosphere from a potential ITER-like fusion reactor located in the Mediterranean Basin and explores if the short range legal exposure limits are exceeded (both locally and downwind). For this, a coupled Lagrangian ECMWF/FLEXPART model has been used to follow real time releases of tritium. This tool was analyzed for nominal tritium operational conditions under selected incidental conditions to determine resultant local and Western Mediterranean effects, together with hourly observations of wind, to provide a short-range approximation of tritium cloud behavior. Since our results cannot be compared with radiological station measurements of tritium in air, we use the NORMTRI Gaussian model. We demonstrate an overestimation of the sequence of tritium concentrations in the atmosphere, close to the reactor, estimated with this model when compared with ECMWF/FLEXPART results. A Gaussian âmesoscaleâ qualification tool has been used to validate the ECMWF/FLEXPART for winter 2010/spring 2011 with a database of the HT plumes. It is considered that NORMTRI allows evaluation of tritium-in-air-plume patterns and its contribution to doses
M5-brane Effective Action as an On-shell Action in Supergravity
We show that the covariant effective action for M5-brane is a solution to the
Hamilton-Jacobi (H-J) equations of 11-dimensional supergravity. The solution to
the H-J equations reproduces the supergravity solution that represents the
M2-M5 bound states.Comment: 20 pages, references added, typos correcte
Market segmentation in behavioral perspective
A segmentation approach is presented using both traditional demographic segmentation bases (age, social class/occupation, and working status) and a segmentation by benefits sought. The benefits sought in this case are utilitarian and informational reinforcement, variables developed from the Behavioral Perspective Model (BPM). Using data from 1,847 consumers and from a total of 76,682 individual purchases, brand choice and price and reinforcement responsiveness were assessed for each segment across the UK cookie (biscuits) market. Building on previous work, the results suggest that the segmentation of brand choice using benefits sought is useful. This is especially the case alongside demographic variables. This article provides a theoretical and practical segmentation approach to both the behavioral psychology literature and the wider marketing segmentation literature
Consumer brand choice: Money allocation as a function of brand reinforcing attributes
Previous applications of the matching law to the analysis of consumer brand choice have shown that the amount of money spent purchasing a favorite brand tends to match the quantity bought of the favorite brand divided by the quantity bought of all other brands. Although these results suggest matching between spending and purchased quantity, branded goods differ qualitatively among themselves, rendering previous matching analyses incomplete. Consumer panel data containing information about more than 1,500 British consumers purchasing four grocery product categories (baked beans, biscuits, fruit juice, and yellow fats) during 52 weeks were analyzed. All the brands purchased were classified according to the level of informational and utilitarian reinforcement they were programmed to offer. An adaptation of the generalized matching law was adopted, in which the amount of money spent was a power function of the quantity bought, informational level of the brand bought, utilitarian level of the brand bought, and a measure of price promotion
Anomalous Roughening in Experiments of Interfaces in Hele-Shaw Flows with Strong Quenched Disorder
We report experimental evidences of anomalous kinetic roughening in the
stable displacement of an oil-air interface in a Hele-Shaw cell with strong
quenched disorder. The disorder consists on a random modulation of the gap
spacing transverse to the growth direction (tracks). We have performed
experiments varying average interface velocity and gap spacing, and measured
the scaling exponents. We have obtained beta=0.50, beta*=0.25, alpha=1.0,
alpha_l=0.5, and z=2. When there is no fluid injection, the interface is driven
solely by capillary forces, and a higher value of beta around beta=0.65 is
measured. The presence of multiscaling and the particular morphology of the
interfaces, characterized by high slopes that follow a L\'evy distribution,
confirms the existence of anomalous scaling. From a detailed study of the
motion of the oil--air interface we show that the anomaly is a consequence of
different local velocities over tracks plus the coupling in the motion between
neighboring tracks. The anomaly disappears at high interface velocities, weak
capillary forces, or when the disorder is not sufficiently persistent in the
growth direction. We have also observed the absence of scaling when the
disorder is very strong or when a regular modulation of the gap spacing is
introduced.Comment: 14 pages, 17 figure
Consumer Behaviour Analysis and Consumer Brand Choice
This is the SECOND of TWO linked articles on consumer behavioural analysis dealing with the Behavioural Perspective Model, which locates consumer behaviour at the intersection of the consumerâs learning history and the consumer situation. As an example of research inspired by the Model, this article presents investigations into consumersâ patterns of brand choice, showing how brand repertoires are formed and how brands are selected within those repertoires
