Empowering the people: ‘empowerment’ and the British Journal of Social Work, 1971–99
Authors: McLaughlin Kenneth 
Published: August 2014

This paper offers a historical and contextual discussion of the concept of empowerment, a term that proliferates in contemporary social work and social policy discourse. First, I discuss the rise of ‘empowerment’ within social policy and social work highlighting some of the factors that have led to it becoming embedded within such circles, discussing the justifications and criticisms of both the term and the interventions that can result from it. Second, I take a more specific look at the way empowerment was discussed and debated within the British Journal of Social Work from the journal’s inception in 1971 through to the end of 1999.
The discussion alerts us of the need to view empowerment not as a fixed a priori good, but as embedded within social and political relationships, and therefore as a concept that can be used for either progressive or regressive social policies and related social work practices.
Multiple solutions for Dirichlet impulsive equations
Authors: Ferrara Massimiliano , Heidarkhani Shapour , Pizzimenti Pasquale F. 
Published: August 2014

Abstract
In this paper we are interested to ensure the existence of
multiple nontrivial solutions for some classes of problems under
Dirichlet boundary conditions with impulsive effects. More
precisely, by using a suitable analytical setting, the existence
of at least three solutions is proved exploiting a recent
three-critical points result for smooth functionals defined in a
reflexive Banach space. Our approach generalizes some well-known
results in the classical framework.
A new species of marine Dactylospora and its phylogenetic affinities within the Eurotiomycetes, Ascomycota
Authors: Pang Ka-Lai , Guo Sheng-Yu , Alias Siti Aisyah , Hafellner Josef , Jones E.B. Gareth 
Published: August 2014

Abstract
An apparently undescribed lignicolous Dactylospora species was collected on a rocky shore in northern Taiwan. The ascomatal morphology of this fungus is similar to other marine Dactylospora species, whereas the unique feature of the new fungus is a distinct perispore forming an ascospore appendage, which comprises a thick and hyaline sheath connected at the septum that opens at both ends. Dactylospora vrijmoediae is described and illustrated as new to science. On the basis of a phylogenetic analysis of the partial 18S and 28S rRNA and RPB2 genes, D. vrijmoediae occurs with other marine species, D. haliotrepha, D. mangrovei, and the terrestrial Sclerococcum sphaerale in an unnamed clade within the Eurotiomycetes, Ascomycota. The marine Dactylospora species are distantly placed and are separated from the terrestrial Dactylospora species included in the analysis (D. lobariella, D. imperfecta).
Classification of irreducible representations of Lie algebra of vector fields on a torus
Authors: Billig Yuly , Futorny Vyacheslav 
Published: August 2014

Abstract
We solve a long standing problem of the classification of all simple
modules with finite-dimensional weight spaces over Lie algebra of
vector fields on n-dimensional torus for any n. This generalizes
the classical result of O.Mathieu on simple weight modules for the
Virasoro algebra (

n
=

${n=1}$

).
Every such module is either of a highest weight type
or is a quotient of a module of tensor fields on a torus, which was
conjectured by Eswara Rao.
Ambitoric geometry I: Einstein metrics and extremal ambikähler structures
Authors: Apostolov Vestislav , Calderbank David M. J. , Gauduchon Paul 
Published: August 2014

Abstract
We present a local classification of conformally equivalent
but oppositely oriented 4-dimensional Kähler metrics which are toric with
respect to a common 2-torus action. In the generic case, these
“ambitoric” structures have an intriguing local geometry depending on a
quadratic polynomial q and arbitrary functions A and B of one variable.
We use this description to classify 4-dimensional Einstein metrics which are
hermitian with respect to both orientations, as well as a class of solutions
to the Einstein–Maxwell equations including riemannian analogues of the
Plebański–Demiański metrics. Our classification can be viewed as a
riemannian analogue of a result in relativity due to R. Debever, N. Kamran, and R. McLenaghan, and is a natural extension of the classification of
selfdual Einstein hermitian 4-manifolds, obtained independently by R. Bryant
and the first and third authors.
These Einstein metrics are precisely the ambitoric structures with vanishing
Bach tensor, and thus have the property that the associated toric Kähler
metrics are extremal (in the sense of E. Calabi). Our main results also
classify the latter, providing new examples of explicit extremal Kähler
metrics. For both the Einstein–Maxwell and the extremal ambitoric structures,
A and B are quartic polynomials, but with different conditions on the
coefficients. In the sequel to this paper we consider global examples, and use
them to resolve the existence problem for extremal Kähler metrics on toric
4-orbifolds with second Betti number

Degrees of strongly special subvarieties and the André–Oort conjecture
Authors: Daw Christopher 
Published: August 2014

Abstract
In this paper we give a new proof of the André–Oort conjecture under the generalised Riemann hypothesis. In fact, we generalise the strategy pioneered by Edixhoven, and implemented by Klingler and Yafaev, to all special subvarieties. Thus, we remove ergodic theory from the proof of Klingler, Ullmo and Yafaev and replace it with tools from algebraic geometry. Our key ingredient is a lower bound for the degrees of strongly special subvarieties coming from Prasad’s volume formula for S-arithmetic quotients of semisimple groups.
Breakdowns in communication of radiological findings: an ethical and medico-legal conundrum
Authors: Berlin Leonard , Murphy Daniel R. , Singh Hardeep 
Published: August 2014

Abstract
Communication problems in diagnostic testing have increased in both number and importance in recent years. The medical and legal impact of failure of communication is dramatic. Over the past decades, the courts have expanded and strengthened the duty imposed on radiologists to timely communicate radiologic abnormalities to referring physicians and perhaps the patients themselves in certain situations. The need to communicate these findings goes beyond strict legal requirements: there is a moral imperative as well. The Code of Medical Ethics of the American Medical Association points out that “Ethical values and legal principles are usually closely related, but ethical obligations typically exceed legal duties.” Thus, from the perspective of the law, radiologists are required to communicate important unexpected findings to referring physicians in a timely fashion, or alternatively to the patients themselves. From a moral perspective, radiologists should want to effect such communications. Practice standards, moral values, and ethical statements from professional medical societies call for full disclosure of medical errors to patients affected by them. Surveys of radiologists and non-radiologic physicians reveal that only few would divulge all aspects of the error to the patient. In order to encourage physicians to disclose errors to patients and assist in protecting them in some manner if malpractice litigation follows, more than 35 states have passed laws that do not allow a physician’s admission of an error and apologetic statements to be revealed in the courtroom. Whether such disclosure increases or decreases the likelihood of a medical malpractice lawsuit is unclear, but ethical and moral considerations enjoin physicians to disclose errors and offer apologies.

On the Performance of the Golden Code in the Presence of Channel Estimation Error in Correlated MIMO Rayleigh Fading Channels
Authors: Ammari Mohamed Lassaad , Abid Wahiba 
Published: August 2014

AbstractThe Golden Code (GC) is a full-rate and full-diversity, space-time code for 2 × 2 multiple-input multiple-output (MIMO) systems with non-vanishing minimum determinant. Thanks to its algebraic construction, the GC achieves diversity-multiplexing gain trade-off and preserves the mutual information. The zero-forcing (ZF) detection is one of the simplest detection techniques that has a low computational complexity and provides a suboptimal performance. The purpose of this work is to investigate the effect of channel estimation error on the performance of the MIMO-ZF receiver for golden coded systems in spatio-temporally correlated Rayleigh fading channels. An upper and a lower bounds of the error probability are delivered and compared to the Monte Carlo simulation results. We quantify the capacity reduction due to the channel estimation error and to the spatio-temporally correlation. A tight lower bound of the ergodic capacity is provided. Numerical results show an excellent agreement between analytic bounds and Monte Carlo simulation curves. Moreover, the performances of the GC, in terms of bit error rate (BER) and channel capacity, are compared with those of the Alamouti coding.

Published: August 2014

AbstractIn this paper, a detailed performance analysis of switch-and-stay combining receivers over non identical distributed extended generalized K fading channels is presented. The analysis has been performed in both noise and interference-limited environments (the level of interference or noise is ignored, respectively). The expressions for the output signal-to-noise (SNR) and signal-to-interference (SIR) probability density function and cumulative distribution function, in a form of Fox's H functions, are presented. Based on this, analytical expressions for evaluating the moments, outage probability, average bit error rate and average channel capacity are derived. The influence of fading and shadowing phenomena, as well as the influence of unbalanced input SNR/SIR on the most important performance metrics is obtained. Presented numerical results are confirmed by Monte Carlo simulations.

Published: August 2014

Abstract

Background: Hypertension is a chronic illness associated with high morbidity and mortality. Once hypertension is diagnosed, starting antihypertensive therapy on a long-term basis along with regular follow up is important. Standardizing treatment guidelines and conducting drug utilization studies at regular intervals help physicians to prescribe drugs rationally. The present study was conducted to analyze the prescription patterns of antihypertensive drugs in a tertiary care referral hospital in Malabar region, Kerala, India.

Methods: The study was conducted at the General Medicine and Cardiology Department involving the in-patients. Patients suffering from essential hypertension with or without other co-morbidities were included in the study. The frequency and proportion of prescribing different groups of antihypertensive drugs as monotherapy or combination therapy, and prescription of fixed drug combinations (FDCs) were analyzed. A total of 200 hypertensive patients were included in the study. Patient data were collected from in-patient’s case sheets and direct interviews with the patients and their observers.

Results: The majority of the patients were females with 56%, whereas the males comprised 44%, with most of the patients suffering from stage-II hypertension. The study revealed that a high proportion of the hypertensive patients had co-morbid diabetes mellitus. The most commonly prescribed class of antihypertensive drugs was angiotensin receptor blockers, followed by calcium channel blockers and β-blockers. With regard to patient therapy, 32.0% received monotherapy, whereas 68.0% received combination therapy, 16% of which received FDCs.

Conclusions: The study shows that clinical pharmacists can play a key role in promoting rational prescription and improving adherence to medication.

Published: August 2014

Abstract: Neuropathy is a frequent complication of diabetes mellitus (DM), increasing with the duration of the disease, poor glycemic control and advanced age. Acute presentation of a neuropathy in the setting of a newly diagnosed type 1 DM is rare and holds a diagnostic challenge.: A 10-year-old girl, presented at the emergency service with complaints of polydipsia, polyuria, asthenia and weight lost over the last 15 days, accompanied by difficulties in flexing the right foot, during the previous week. The patient denied any pain, paresthesias, or altered sensibility. There was no fever documented, or recent infectious intercurrence or trauma. On physical examination, she was conscious, collaborative and space and time-orientated, had a diminished strength in the right foot, namely in the dorsiflexion, conditioning a steppage gait ipsilateral. Hyperalgesia was felt in the dorsum of the right feet to the ankle. DM type 1 was diagnosed based on serum glucose of 629 mg/dL and mild ketoacidosis. Investigation for infectious, immune and nutritional aetiologies for the mononeuropathy was negative. Electrophysiological study was suggestive of a lesion of the peroneal nerve on the popliteal cesspit, but was not conclusive. The patient started physiotherapy during her hospital stay and exhibited a slight improvement in the dorsiflexion of the foot. Four months later she was asymptomatic and with good glycaemic control.: Diabetic neuropathy is a heterogeneous group that still lacks adequate comprehension. Its approach is empirical and demands exclusion of other etiologies. A definitive diagnosis is not always possible and sometimes is retrospective.

Published: August 2014

Abstract

Aims: To evaluate values of foetal T/QRS ratios in pregnancies complicated by threatened preterm labour treated with intravenous infusions of fenoterol using non-invasive methods with transabdominal electrodes.

Materials and Methods: The study group consisted of 451 Caucasian women (63 preterm pregnancies and 327 healthy controls) whose pregnancies ranged from 28 to 37 gestational weeks. Foetal electrocardiograms were recorded and T/QRS ratios were calculated by KOMPOREL software (ITAM, Zabrze, Poland). The first recording was performed 30 min after the start of fenoterol infusion and the second 2 days after finishing tocolysis. T/QRS ratio variables were calculated. One-way analysis of variance was carried out.

Results: Significantly higher mean values of the T/QRS ratio were observed in pregnancies during tocolytic treatment in comparison to controls and pregnancies after tocolysis (P=0.0158 and P=0.0071, respectively). The T/QRS ratio values fall again shortly after finishing intravenous tocolysis.

Conclusions: The T/QRS ratio is one of the methods used for non-invasive foetal distress assessment that can be used in antepartum foetal monitoring in complicated pregnancies. Raised values of the T/QRS ratio in the foetus during tocolysis with fenoterol and next its fall to values observed in physiological pregnancies may indicate transient worsening of fetal well-being, however, additional research is required.
A spectral method for isotropic diffusion equation with random concentration fluctuations of incoming flux of particles through circular-shaped boundaries
Authors: Sabelfeld Karl K. , Levykin Alexander I. 
Published: August 2014

Abstract
We present in this paper a further development of the stochastic spectral method for solving boundary value problems
in domains which are composed by a set of overlapped discs first suggested by the first author in Appl. Math. Comput. 219 (2013), no. 10, 5123–5139].
We study statistical characteristics of the solution to isotropic diffusion problem in response to fluctuating
incoming flux of particles through the circular-shaped boundaries.
Performance of the method is illustrated by a series of numerical experiments.
The method can be considered as a direct inversion of the integral Poisson formula
representing the solution in the disc, so it is highly accurate and fast for the class of domains considered.
This makes possible to solve an ensemble of equations with random samples of boundary conditions
and calculate the desired statistical characteristics.

AbstractThe cell establishes heritable patterns of active and silenced chromatin via interacting factors that set, remove, and read epigenetic marks. To understand how the underlying networks operate, we have dissected transcriptional silencing in pericentric heterochromatin (PCH) of mouse fibroblasts. We assembled a quantitative map for the abundance and interactions of 16 factors related toPCHin living cells and found that stably bound complexes of the histone methyltransferaseSUV39H1/2 demarcate thePCHstate. From the experimental data, we developed a predictive mathematical model that explains how chromatin‐boundSUV39H1/2 complexes act as nucleation sites and propagate a spatially confinedPCHdomain with elevated histoneH3 lysine 9 trimethylation levels via chromatin dynamics. This “nucleation and looping” mechanism is particularly robust toward transient perturbations and stably maintains thePCHstate. These features make it an attractive model for establishing functional epigenetic domains throughout the genome based on the localized immobilization of chromatin‐modifying enzymes.
