Configuring ATL Transformations in MOSKitt 1

Model transformations need to be configured in order to satisfy particular user requirements in real scenarios. This paper introduces an strategy for configuring ATL transformations. This strategy, that is currently in practice in the MOSKitt tool, follows a model driven approach, where both the specification of configuration options and the user selections of those options are implemented as models. Additionally, the user interfaces that are provided by MOSKitt for selecting the configuration options are briefly introduced.
Asymmetric Dynamics in Optimal Variance Adaptation

It has long been recognized that sensory systems adapt to their inputs. Here we formulate the problem of optimal variance estimation for a broad class of nonstationary signals. We show that under weak assumptions, the Bayesian optimal causal variance estimate shows asymmetric dynamics: an abrupt increase in variance is more readily detectable than an abrupt decrease. By contrast, optimal adaptation to the mean displays symmetric dynamics when the variance is held fixed. After providing several empirical examples and a simple intuitive argument for our main result, we prove that optimal adaptation is asymmetrical in a broad class of model environments. This observation makes specific and falsifiable predictions about the time course of adaptation in neurons probed with certain stimulus ensembles.
Impact of routing and traffic distribution on the performance of network admission control

In contrast to link admission control (LAC), which limits the truffle on a single link, network admission control (NAC) methods limit the traffic within a network. In this paper we present four basic budget based NAC approaches that have different complexity. They categorize most resource management schemes from a performance point of view regarding the maximum bandwidth utilization. Our results show that the option of single- or multi-path routing has a significant impact on the NAC performance while it is rather independent of the structure of the traffic matrix.
Workplace risks and stressors as predictors of burnout: The moderating impact of job control and team efficacy

Air medical healthcare (AMH) professionals care for critically-ill individuals while conveying them to healthcare centres from distant, and frequently dangerous, locations. AMH professionals experience additional health and safety issues beyond the “typical” stressors faced by other healthcare professionals. Therefore, we integrated the safety and psychosocial health literatures to examine the relationship between workplace stressors (risk perception, worries, and patient-care barriers) and two components of burnout (emotional exhaustion; depersonalization), and the moderating impact of job control and team effi cacy for 106 Canadian AMH professionals. Worries over medical hassles and barriers to patient care uniquely predicted emotional exhaustion. Lack of perceived control over one’s job was related to exhaustion and depersonalization after controlling for stressors. Job control and team effi cacy buffered some of the stressor-burnout relationships. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd. JEL Classifi cation: J28
The use of catalytic models as tools for elucidating the clinical and epidemiological features of trachoma.

A change in the clinical pattern of trachoma from a grave to a milder form has been noted in several endemic areas in recent years and has been attributed to improvements in bio-physical conditions, as well as to specific control measures. The disease, thus modified, frequently presents difficulty in diagnosis under field conditions, and equivocal cases, which are sometimes encountered in relatively large numbers, pose a problem in the assessment of over-all incidence, prevalence and relative gravity of trachoma in the area. The problem assumes particular importance in field studies, such as therapeutic and vaccination trials.In an attempt to determine by epidemiological methods the true nature of these clinically equivocal cases, the data collected during a survey of the prevalence of trachoma in Taiwan have been subjected to an intensive study with the aid of catalytic models. The evidence is that most, if not all, of these cases are trachomatous.
Contingency in everyday surgical work

This paper concerns a qualitative study exploring the nature of surgical work with a group of 34 surgeons involved in treating urinary incontinence. Sources of surgical variation are identified from surgeons' own accounts of their work as well as observation of the selection of patients and operative procedures, and the operative process itself. A typology of contingency, consisting of three categories of contingency (case, surgeon and external), was found in this area of everyday surgical work. In developing this typology, theoretical and philosophical ideas about habitus and disposition, and practical and technical knowledge, are considered and extended to help to understand the nature of surgical practice. These ideas may also be useful in explaining some of the apparent tensions between evidence-based surgery and everyday surgical work.
A sub-region priority reaching control scheme with a fuzzy-logic algorithm for an underwater vehicle subject to uncertain restoring forces

This paper presents an adaptive sub-region priority reaching controller with a fuzzy logic algorithm for an underwater vehicle. In this method, the sub-region priority reaching control law is merged with a fuzzy technique to manage the generalization of the underwater vehicle set-point control problem. The fuzzy technique is used to handle multiple sub-region criteria. These criteria are: depth constraint, avoiding the region with an obstacle inside it, ensuring visibility of the feature during visual servoing and region shape constraint. Due to the unknown gravitational and buoyancy forces, an adaptive term is adopted in the proposed controller. Moreover, the unit quaternion representation is used in order to achieve a singularity-free attitude representation. The stability analysis is carried out using the Lyapunov type approach. Simulation results are presented to demonstrate the effectiveness of the proposed control technique.
A tree based recovery algorithm for block sparse signals

The structure of block sparsity in multi-band signals is prevalent. Performance of recovery algorithms that taking advantage of the block sparsity structure is promising in the compressed sensing framework. In this paper, we propose a binary tree based recovery algorithm for block-sparse signals, where we exploit the fact that each block may have zero and nonzero elements both. The proposed algorithm improves the current algorithms through iteratively separating the recovered blocks of signals into two smaller blocks. Therefore, greedy searching based algorithm is possible to obtain more accurate basis for signal recovery. Simulations are performed and the results show the improvements over current block-based recovery algorithms.
Evaluating Displayed Depression Symptoms on Social Media Sites

Social networking sites (SNSs) are immensely popular and allow for display of personal information, including references to depression. Evaluating displayed content on a SNS for research purposes requires a systematic approach and a precise data collection instrument. The purpose of this paper is to describe one approach to the development of a research codebook for depression so that others may develop and test their own codebooks for use in SNS research. The depression SNS research codebook was grounded in ethics, theory and clinical criteria.The key elements in the codebook developmental process included an iterative team approach to develop variables of interest and data collection sheet layout. Training protocols involve coding practice and reliability assessments. Interrater reliability remains a critical assessment tool. Codebook successes include consistently high interrater reliability. Challenges include time investment in coder training, SNS server changes, and social or cultural norms regarding public displays of mental health. We provide detailed information about a systematic approach to codebook development so that other researchers may use this structure to develop and test their own codebooks for use in SNS research. Future directions for the codebook include expanding areas of interest such as anxiety or other depression evaluation criteria, and expansion to other SNSs such as Twitter.
Tailoring the core electron density in modulation-doped core−multi-shell nanowires

We show how a proper radial modulation of the composition of core-multi-shell nanowires (NWs) critically enhances the control of the free-carrier density in the high-mobility core with respect to core−single-shell structures, thus overcoming the technological difficulty of fine tuning the remote doping density. We calculate the electron population of the different NW layers as a function of the doping density and of several geometrical parameters by means of a self-consistent Schrödinger–Poisson approach: free carriers tend to localize in the outer shell and screen the core from the electric field of the dopants.
Gendered media, changing intimacy: internet-mediated transnational communication in the family sphere

This article explores the ways in which migrants use the internet to maintain family relationships and how the difference in digital knowledge and skills between men and women serves to transform the power dynamics in the family sphere transnationally. It examines the intersection of the research areas of transnationalism, digital inequality and family. While the discussion of digital inequalities is seldom embedded in the context of transnational families, research on migrants and their families rarely investigates the impacts of digital inequality on gendered power dynamics. Focusing on the context of Chinese migrants in London and their ageing parents in China, this study identifies how the supposedly feminine role of care and intimacy is now increasingly reassigned to male family members in a transnational process as the internet has largely replaced other media to become the most significant tool in transborder family communication. Women in transnational families are thus silenced. Three modes of coping skills have been adopted by these women; that is, absence, assistance and empowerment. By identifying modes of resistance, this article highlights spaces of agency under the gendered structure of family communication and their potential limits.
The production of disability research in human geography: an introspective examination

The ‘geographies of disability’ is an important and evolving area of scholarship within human geography. Uniting the disparate areas of inquiry in this sub‐discipline are researchers’ shared interests in understanding processes of disablement and socio‐spatial experiences of disability. What drives human geographers to engage with this scholarship? We address this and other introspective questions through presenting an analysis of the findings of an online survey conducted with 30 such disability researchers. The overriding purpose is to understand how and why these researchers do what they do. Our presentation of the survey findings is divided into four organizational categories: (1) the researcher; (2) the inquiry; (3) the research outputs; and (4) the institutions. A key finding is that conducting disability research in human geography is very much about negotiating around or through constraints while identifying and enacting enablers in order to accomplish goals associated with producing disability research.
Astrochemistry of sub-millimeter sources in Orion. Studying the variations of molecular tracers with changing physical conditions

Cornerstone molecules (CO, H2CO, CH3OH, HCN, HNC, CN, CS, SO) were observed toward seven sub-millimeter bright sources in the Orion molecular cloud in order to quantify the range of conditions for which individual molecular line tracers provide physical and chemical information. Five of the sources observed were protostellar, ranging in energetics from 1−500 L� , while the other two sources were located at a shock front and within a photodissociation region (PDR). Statistical equilibrium calculations were used to deduce from the measured line strengths the physical conditions within each source and the abundance of each molecule. In all cases except the shock and the PDR, the abundance of CO with respect to H2 appears significantly below (factor of ten) the general molecular cloud value of 10 −4 . Formaldehyde measurements were used to estimate a mean temperature and density for the gas in each source. Evidence was found for trends between the derived abundance of CO, H2CO, CH3OH, and CS and the energetics of the source, with hotter sources having higher abundances. Determining whether this is due to a linear progression of abundance with temperature or sharp jumps at particular temperatures will require more detailed modeling. The observed methanol transitions require high temperatures (T > 50 K), and thus energetic sources, within all but one of the observed protostellar sources. The same conclusion is obtained from observations of the CS 7-6 transition. Analysis of the HCN and HNC 4-3 transitions provides further support for high densities n > 10 7 cm −3 in all the protostellar sources. The shape of the CO 3-2 line profile provides evidence for internal energetic events (outflows) in all but one of the protostellar sources, and shows an extreme kinematic signature in the shock region. In general, the CO line and its isotopes do not signif- icantly contaminate the 850 µm broadband flux (less than 10%); however, in the shock region the CO lines alone account for more than two thirds of the measured sub-millimeter flux. In the energetic sources, the combined flux from all other measured molecular lines provides up to an additional few percent of line contamination.
FairMAC: fair sharing of multi-access channels in WLAN hotspots

We identify two typical problems in WLAN hotspots that result in unbounded unfairness between upstream and downstream flows. The first unfairness problem arises due to the uniformity of the MAC layer protocol at the access point (AP) and user nodes that result in equal share to the AP and the user nodes but not to the individual flows. The second unfairness problem arises due to the inability of the physical layer to distinguish frame errors due to hidden terminal based collisions and frame errors due to poor signal strength. We present FairMAC, a deployable solution that addresses these unfairness problems without requiring a change to the 802.11 protocol. Thus, our solution is immediately deployable in the millions of currently operational hotspots. We evaluate the performance of our protocol using simulations and a prototype implementation. We show that FairMAC provides fair access to all the flows regardless whether they are originating at the AP or a host.
Passive protection against Pseudomonas aeruginosa infection in an experimental leukopenic mouse model

An experimental leukopenic mouse model was used to evaluate the protective capacities of immunoglobulin G (IgG) fractions directed against toxin A (AT-IgG), elastase (AE-IgG), and lipopolysaccharide (ALPS-IgG) against fatal Pseudomonas aeruginosa infection. Statistically significant protection, as measured by long-term survival, was observed only when mice were treated with serotype-specific ALPS-IgG. The mean lethal dose for P. aeruginosa could be increased by as much as 6,600-fold for mice given ALPS-IgG as compared to mice which received only normal rabbit IgG. ALPS-IgG afforded high levels of protection, even when administered up to 6 h postchallenge. Experiments designed to monitor the growth and spread of a locally administered challenge showed that ALPS-IgG prevented bacteremia and organ colonization, which were pronounced in control animals. The effectiveness of combined antibiotic and immune therapy was tested. Gentamicin alone or in combination with AT-IgG or AE-IgG provided no detectable protection. However, its use with ALPS-IgG afforded substantially higher levels of protection than ALPS-IgG alone.
Toxic effect of NiCl2 on development of the bursa of Fabricius in broiler chickens

This study was conducted with objective of evaluating the toxic effects of nickel chloride (NiCl2) on development of bursa of Fabricius in broilers fed on diets supplemented with 0, 300, 600 and 900 mg/kg of NiCl2 for 42 days by using the methods of experimental pathology, flow cytometry (FCM), and quantitative real-time polymerase chain reaction (qRT-PCR). The results showed that dietary NiCl2 in 300 mg/kg and over induced toxic suppression in the bursal development, which was characterized by decreasing lymphocytes histopathologically and relative weight, increasing G0/G1 phase (a prolonged nondividing state), reducing S phase (DNA replication) and proliferating index, and increasing percentages of apoptotic cells. Concurrently, the mRNA expression levels of bax, cytochrome c (cyt c), apoptotic peptidase activating factor 1 (Apaf-1), caspase-3, caspase-6, caspase-7 and caspase-9 were increased and the bcl-2 mRNA expression levels were decreased. The toxic suppression of bursal development finally impaired humoral immunity duo to the reduction of B lymphocyte population and B lymphocyte activity in the broiler chicken. This study provides new evidences for further studying the effect mechanism of Ni and Ni compoundson B-cell or bursa of Fabricius.
1,4-Benzoquinone Reductase from Phanerochaete chrysosporium: cDNA Cloning and Regulation of Expression

ABSTRACT A cDNA clone encoding a quinone reductase (QR) from the white rot basidiomycete Phanerochaete chrysosporium was isolated and sequenced. The cDNA consisted of 1,007 nucleotides and a poly(A) tail and encoded a deduced protein containing 271 amino acids. The experimentally determined eight-amino-acid N-terminal sequence of the purified QR protein from P. chrysosporium matched amino acids 72 to 79 of the predicted translation product of the cDNA. The Mr of the predicted translation product, beginning with Pro-72, was essentially identical to the experimentally determined Mr of one monomer of the QR dimer, and this finding suggested that QR is synthesized as a proenzyme. The results of in vitro transcription-translation experiments suggested that QR is synthesized as a proenzyme with a 71-amino-acid leader sequence. This leader sequence contains two potential KEX2 cleavage sites and numerous potential cleavage sites for dipeptidyl aminopeptidase. The QR activity in cultures of P. chrysosporium increased following the addition of 2-dimethoxybenzoquinone, vanillic acid, or several other aromatic compounds. An immunoblot analysis indicated that induction resulted in an increase in the amount of QR protein, and a Northern blot analysis indicated that this regulation occurs at the level of theqr mRNA.
Genetic polymorphism of cytochrome P4501A1 and susceptibility to oral squamous cell carcinoma and oral precancer lesions associated with smoking/betel use.

BACKGROUND The importance of the CYP1A1 polymorphisms at exon 7 (Ile/Val) and 3'-untranslated region (3'-UTR) has been controversial in oral squamous cell carcinoma (OSCC) or head and neck SCC (HNSCC) denoting the value of exploring the correlation between these polymorphisms and risk of betel/smoking associated OSCC. It is also important to evaluate the association between CYP1A1 polymorphisms and susceptibility of oral precancerous lesion (OPL) to confirm the findings in OSCC cases. METHODS We examined polymorphic prevalence of CYP1A1 at exon 7 (Ile/Val) and 3'-UTR in 106 cases with OSCC, 60 cases with OPL, and 146 controls. DNA isolated from surgical specimens and whole blood was used for PCR-based genotyping. RESULTS The prevalence of the CYP1A1 A/G genotype (Ile/Val) and G/G genotype (Val/Val) in exon 7 of cases with OSCC (79.2 and 7.6%) and OPL (68.3 and 10%) were significantly higher than in controls (53.4 and 1.4%) (P < 0.0001). The novelty of the present study is that we identified the onset age of OSCC in CYP1A1 A/G genotype to be significantly younger than that in A/A genotype (P < 0.01). No significant difference was seen between cases and controls regarding the polymorphisms at 3'-UTR. CONCLUSION The findings indicate that the individuals with the CYP1A1 exon 7 containing G allele were at increased risk for OSCC and OPL.
A Case Study on Regularity in Cellular Network Deployment

This letter aims to validate the β-Ginibre point process as a model for the distribution of base station locations in a cellular network. The β-Ginibre is a repulsive point process in which repulsion is controlled by the β parameter. When β tends to zero, the point process converges in law towards a Poisson point process. If β equals to one it becomes a Ginibre point process. Simulations on real data collected in Paris, France, show that base station locations can be fitted with a β-Ginibre point process. Moreover, we prove that their superposition tends to a Poisson point process as it can be seen from real data. Qualitative interpretations on deployment strategies are derived from the model fitting of the raw data.
The Natural Development and Trainability of Plyometric Ability During Childhood

THE INCLUSION OF PLYOMETRICS WITHIN YOUTH-BASED STRENGTH AND CONDITIONING PROGRAMS IS BECOMING MORE POPULAR AS A MEANS TO DEVELOP STRETCH-SHORTENING CYCLE ABILITY. PLYOMETRIC TRAINING ADAPTATIONS HAVE PREVIOUSLY BEEN REPORTED FOR RUNNING VELOCITY, POWER, AGILITY, AND RUNNING ECONOMY, AND THEREFORE, ATHLETES SHOULD BE EXPOSED TO THIS TRAINING MODALITY AT SOME POINT DURING THEIR TRAINING PROGRAM. HOWEVER, SOME UNCERTAINTY STILL EXISTS WITH REGARD TO PROGRAM DESIGN, ESPECIALLY WHEN TAKING GROWTH AND MATURATIONAL FACTORS INTO ACCOUNT. THIS ARTICLE REVIEWS THE CURRENT YOUTH-BASED PLYOMETRIC LITERATURE AND PROVIDES A TRAINING PROGRESSION MODEL BASED AROUND THE LONG-TERM DEVELOPMENT OF YOUNG ATHLETES.
Health of women ex‐prisoners

In an attempt to assist understanding of the specific health problems of women prisoners, the research reported here described the health of a volunteer group of female ex‐prisoners (N = 30), comparing them with a group of women from similar life circumstances who had not been imprisoned (N = 30), and with data from an Australian community study. The following instruments were administered: a structured interview; General Health Questionnaire (30 item) (GHQ‐30) Medical Outcomes Study. Short Form‐36 items (SF‐36) Kaufman Brief Intelligence Test (K‐BIT). Physical and mental health effects specifically related to imprisonment were examined. Both ex‐prisoners and non‐prisoners had poor mental and physical health compared‐with Australian women generally. This poor level of health functioning was probably related to the method of recruitment of the sample, reflecting the fact that women from poor socioeconomic levels who are receiving help from welfare agencies tend to be in poor health. The ex‐prisoners functi.
