Qualities of Effective Leadership in Higher Education

The leadership of Higher Education institutions has been placed under increasing scrutiny since the 1980s with the expansion of student numbers, changes in funding for student places, increased marketization and student choice, and continuing globalisation of the sector. In this climate of change Higher Education institutions have been required to consider how to develop their leaders and what might be appropriate leadership behaviour to enable adaptation to these new circumstances. When the various paradigms of leadership encountered in the Higher Education sector are compared with established leadership theory and practice it is possible to identify further intricacies in the development of Higher Education leaders. Further consideration of practicalities within Higher Education identifies whether competence frameworks might assist in leadership development. An examination of a recently-developed comprehensive framework of leadership capabilities applied in an alternative sector leads to an evaluation as to whether the same constructs apply to the demands placed upon leaders in Higher Education. Analysis demonstrates that, with minor changes in terminology, the constructs remain appropriate and valid. The definitions of activities and behaviours offer insight into how Higher Education leaders could be developed and therefore form a potential framework of leadership capabilities for Higher Education.
First results from COLDEX applicable to the LHC cryogenic vacuum system.

A cold bore experiment (COLDEX) has been installed in the electron-positron accumulator (EPA) at CERN. The ~2 m long COLDEX cryostat, that may be cooled to below 3 K, is fitted with an actively cooled perforated beam screen to simulate the conditions in the cold arcs of the LHC. Initially, gas desorption yields were obtained using an external synchrotron radiation beam line by exposing the beam screen to grazing incident radiation with a critical energy of 194 eV. In an extended period of EPA operation and during a dedicated period for LHC studies, COLDEX was installed into the EPA ring to study more specifically the influence of the bunched positron and electron beams with the cold bore / beam screen vacuum system. The results from these experiments and some predictions applicable for the LHC will be presented.
Popov Form Computation for Matrices of Ore Polynomials

Let F[∂ ; σ, δ] be a ring of Ore polynomials over a field. We give a new deterministic algorithm for computing the Popov form P of a non-singular matrix A ∈ F[∂ ; σ, δ]n x n. Our main focus is to ensure controlled growth in the size of coefficients from F in the case F = K(z), and even K = Q. Our algorithms are based on constructing from A a linear system over F and performing a structured fraction-free Gaussian elimination. The algorithm is output sensitive, with a cost that depends on the orthogonality defect of the input matrix: the sum of the row degrees in A minus the sum of the row degrees in P. The resulting bit-complexity for the differential and shift polynomial case over Q(z) improves upon the previous best.
Quantitative Bayesian model‐based analysis of amide proton transfer MRI

Amide Proton Transfer (APT) reports on contrast derived from the exchange of protons between amide groups and water. Commonly, APT contrast is quantified by asymmetry analysis, providing an ensemble contrast of both amide proton concentration and exchange rate. An alternative is to sample the off‐resonant spectrum and fit an exchange model, permitting the APT effect to be quantified, correcting automatically for confounding effects of spillover, field inhomogeneity, and magnetization transfer. Additionally, it should permit amide concentration and exchange rate to be independently quantified. Here, a Bayesian method is applied to this problem allowing pertinent prior information to be specified. A three‐pool model was used incorporating water protons, amide protons, and magnetization transfer effect. The method is demonstrated in simulations, creatine phantoms with varying pH and in vivo (n = 7). The Bayesian model‐based approach was able to quantify the APT effect accurately (root‐mean‐square error < 2%) even when subject to confounding field variation and magnetization transfer effect, unlike traditional asymmetry analysis. The in vivo results gave approximate APT concentration (relative to water) and exchange rate values of 3 × 10−3 and 15 s−1. A degree of correlation was observed between these parameter making the latter difficult to quantify with absolute accuracy, suggesting that more optimal sampling strategies might be required.

Monolithic reconfigurable SC power converter with adaptive gain control and on-chip capacitor sizing

This paper presents a monolithic reconfigurable step-down switched-capacitor (SC) power converter for self-powered microsystems. The design features an efficient step-down SC power stage with adaptive gain control and on-chip capacitor sizing. The adaptive gain control helps the converter maintain high efficiency continuously. Meanwhile, the size-adjustable pumping capacitors allow the output voltage to be regulated at different desired levels, even with a constant by 50% duty ratio. The monolithic implementation effectively suppresses the switching noises and glitches caused by parasitic components resulting from traditional bonding, packaging, and PCB wiring. The design has been sent for fabrication with a 180-nm CMOS process. Post-layout fully-transistor based simulations show that the converter is capable of precisely providing a variable power supply Vout from 0.9 to 1.65 V. It achieves a maximum efficiency of 89%, when Vout is regulated at 1.65 V and at a switching frequency of 4 MHz.
Methodologies for modelling energy and amino acid responses in poultry

The objective of this paper is to present some of the issues faced by those whose interest is to predict responses in poultry, concentrating mainly on those related to the prediction of voluntary food intake, as this should be the basis of models designed to optimise both performance and feeding programmes. The value of models designed to predict growth or reproductive performance has been improved inestimably by making food intake an output from, as opposed to an input to, such models. Predicting voluntary food intake requires the potential of the bird to be known, be this the growth of body protein or lipid, the growth of feather protein, or the rate at which yolk and albumen may be deposited daily in the form of an egg, and some of the issues relating to the description of potentials are discussed. This potential defines the nutrients that would be required by the bird on the day, which can be converted to a desired food intake by dividing each requirement by the content of that nutrient in the feed. There will be occasions when the bird will be unable to consume what is required, and predicting the magnitude of these constraints on intake and performance provides the greatest challenge for modellers. This paper concentrates on some issues raised in defining the nutrient requirements of an individual, on constraints such as high temperatures and the social and infectious environment on voluntary food intake, on some recent differences in the response to dietary protein that have been observed between the major broiler strains, and on the methodologies used to deal with populations of birds, and finally with broiler breeder hens, whose food intake is constrained by management, not by the environment. These issues suggest that there are still challenges that lie ahead for those wishing to predict responses to nutrients in poultry. It is imperative, however, that the methods used to measure the numbers that make theories work, and that the theories themselves, are robust and unambiguous such that the resultant models can be used to assist the poultry Industry to become more efficient especially when designing feeds and feeding programmes.

Glomerulonephritis and malignancy: a population-based analysis.

BACKGROUND An association between glomerulonephritis and malignant tumors has previously both been found and discarded in clinical series, but to our knowledge never has been tested in a population-based setting. METHODS The Danish Kidney Biopsy Registry includes all kidney biopsies performed from 1985. Using a unique personal identification number, each person in the registry to the National Population Registry and the Danish Cancer Registry were linked. Cancer occurrence after the biopsy was compared in patients with morphological, glomerular diseases with that of the general Danish population, taking into account sex, age, calendar period and time since biopsy, and the 95% confidence interval (95% CI) for the observed-to-expected rates was calculated, assuming a Poisson distribution. Cancer occurrence was stratified to <1 year, 1 to 4, and >or=5 years after a biopsy. RESULTS A total of 102 de novo cancers were found in 1958 patients. These cancers represent a two- to threefold excess of the expected number at <1 and 1 to 4, but not >or=5 years after a biopsy. Non-Hodgkin's lymphomas were observed six to eight times more than expected. Cancer excess was seen in glomerulonephritides with a known or suspected virus etiology. CONCLUSIONS The excess cancer rate could be the result of underlying undiagnosed tumors whose antigens have initiated glomerulonephritis, or the immunosuppressive therapy that initiated or energized tumor cells. Based on the findings in our study, there is some support for an association to persistent viruses causing first the glomerulonephritides and then the malignancies, perhaps through a common pathogenesis. This calls for other studies to be done that are specifically designed to investigate this issue, with more data on patient characteristics and confounders.
Influence of surface treatment of CdZnTe for the radiation detector

CdZnTe is the most promising material for the room temperature radiation detector. Previously many studies have been done for the fabrication process of CdZnTe radiation detector. Usually the CdZnTe surface was mechanically polished and etched with bromine/methanol. The Au or Pt was deposited to make the metal contact on the crystal. From the previous works, it was concluded that the dark current of the CdZnTe detector is greatly influenced by the surface roughness. We study the fabrication process of CdZnTe detector with indium electrode contacts. The dependency of the dark current on the surface treatment was studied. The CdZnTe crystal is treated thermally during the electrode deposition, and the effect of the thermal treatment to the detector performance is studied.
Do blog citations correlate with a higher number of future citations? Research blogs as a potential source for alternative metrics

Journal‐based citations are an important source of data for impact indices. However, the impact of journal articles extends beyond formal scholarly discourse. Measuring online scholarly impact calls for new indices, complementary to the older ones. This article examines a possible alternative metric source, blog posts aggregated at ResearchBlogging.org, which discuss peer‐reviewed articles and provide full bibliographic references. Articles reviewed in these blogs therefore receive “blog citations. ” We hypothesized that articles receiving blog citations close to their publication time receive more journal citations later than the articles in the same journal published in the same year that did not receive such blog citations. Statistically significant evidence for articles published in 2009 and 2010 support this hypothesis for seven of 12 journals (58%) in 2009 and 13 of 19 journals (68%) in 2010. We suggest, based on these results, that blog citations can be used as an alternative metric source.
Effect of Viscosity upon Hydrodynamically Controlled Natural Aggregates of Animal Cells Grown in Stirred Vessels

The effect of medium viscosity upon cell growth and aggregate characteristics of baby hamster kidney (BHK) cells cultivated in stirred tanks was evaluated. Two thickening agents were tested, 9300 MW dextran and a low‐viscosity sodium (carboxymethyl)‐cellulose; both were used in two different sets of experiments: (i) 250 cm3 Wheaton spinner flasks with a ball impeller operated at 45 rpm; (ii) 500 cm3 Corning spinner flasks with a paddle impeller, operated at constant power dissipation (88 cm2 s−3) Aggregate diameter and the fraction of cells in aggregates increased with the increase in viscosity. Power laws were applied to the experimental results. A dependence of aggregate size upon power dissipation of the order of –0.19 and kinematic viscosity of 0.34 and 0.49 for the constant agitation and constant power dissipation tests were obtained, respectively. A model based upon the entire universal‐equilibrium range (i.e., the entire spectrum of isotropic eddies) was used to predict theoretical relationships between the variables studied. The model leads to a power dependence of –0.25 for the energy dissipated in the entire universal‐equilibrium range and between 0.25 and 0.5 for the kinematic viscosity in the viscous dissipation subrange, depending on the energy correlation used; it also gives a good explanation for the dependence of aggregate size on the hydrodynamics of the vessel.
Convulsant hydrazides. II. Comparison of electrical changes and enzyme inhibition induced by the administration of thiosemicarbazide.

Progressive enzymatic inhibition in the l -glutamic acid decarboxylase system has been shown to parallel progressive stages of developing electrical seizure activity in isolated cortical, normal cortical and subcortical tissues following administration of thiosemicarbazide. At all stages additions of coenzyme increased enzyme activity indicating that apoenzyme had not been destroyed. Concurrent measurements of the synthesis of pyridoxal phosphate indicated that coenzyme production was not altered by thiosemicarbazide. It was suggested, therefore, that the mode of action of thiosemicarbazide in producing seizures is by blockade of the coenzyme, possibly through formation of an inert complex. Parallel studies of electrical and enzymatic activity indicated that seizures are not precipitated by the drug. Thiosemicarbazide appears rather to set up conditions of instability through enzymatic inhibition, and spontaneous electrical activity then triggers the convulsions. Subcortical structures showed slightly higher endogenous l -glutamic acid decarboxylase activity and greatest unsaturation of the apoenzyme. These factors are considered to contribute to the preferential action of thiosemicarbazide observed at subcortical sites.
Exterior templates for capacitance computations [interconnections]

The computation of the capacitance coefficients for alternative interconnect configurations requiring repeated calculations as the configurations are changed can be substantially accelerated by using an "exterior template", that is, a set of "template capacitors" connected to the surface of the smallest rectangular region encompassing the planned interconnects. These template capacitors represent the effect of the medium for the fringing field outside the rectangle, and they eliminate the need to sample the fringing field every time a new calculation is made. The template capacitors can be determined by using the theory of infinite grids to eliminate almost entirely the medium-truncation error. All this works for both two-dimensional and three-dimensional (3-D) configurations, and it is especially advantageous in the 3-D case.
Valsartan, captopril, or both in myocardial infarction complicated by heart failure, left ventricular dysfunction, or both.

BACKGROUND Angiotensin-converting-enzyme (ACE) inhibitors such as captopril reduce mortality and cardiovascular morbidity among patients with myocardial infarction complicated by left ventricular systolic dysfunction, heart failure, or both. In a double-blind trial, we compared the effect of the angiotensin-receptor blocker valsartan, the ACE inhibitor captopril, and the combination of the two on mortality in this population of patients. METHODS Patients receiving conventional therapy were randomly assigned, 0.5 to 10 days after acute myocardial infarction, to additional therapy with valsartan (4909 patients), valsartan plus captopril (4885 patients), or captopril (4909 patients). The primary end point was death from any cause. RESULTS During a median follow-up of 24.7 months, 979 patients in the valsartan group died, as did 941 patients in the valsartan-and-captopril group and 958 patients in the captopril group (hazard ratio in the valsartan group as compared with the captopril group, 1.00; 97.5 percent confidence interval, 0.90 to 1.11; P=0.98; hazard ratio in the valsartan-and-captopril group as compared with the captopril group, 0.98; 97.5 percent confidence interval, 0.89 to 1.09; P=0.73). The upper limit of the one-sided 97.5 percent confidence interval for the comparison of the valsartan group with the captopril group was within the prespecified margin for noninferiority with regard to mortality (P=0.004) and with regard to the composite end point of fatal and nonfatal cardiovascular events (P<0.001). The valsartan-and-captopril group had the most drug-related adverse events. With monotherapy, hypotension and renal dysfunction were more common in the valsartan group, and cough, rash, and taste disturbance were more common in the captopril group. CONCLUSIONS Valsartan is as effective as captopril in patients who are at high risk for cardiovascular events after myocardial infarction. Combining valsartan with captopril increased the rate of adverse events without improving survival.
A study on the hearing of children with non-syndromic cleft palate/lip

Summary Children with cleft lip/palate often present otitis media as a result of anatomic and/or functional alterations of the Eustachian tube. Aim to analyze the results of Basic Audiologic Evaluation (BAE) and Auditory Processing Screening (APS) in children with cleft lip/palate. Study design prospective cross-sectional cohort. Materials and methods Forty-four male and female children, within the 8 to 14 age range with non-syndromic cleft lip/palate, referred by the institution where the study was carried out. The BAE was made up by an interview, otoscopy, threshold tonal audiometry, logoaudiometry and impedance test. The APS was made up of 3 basic tests: Sound Localization Test, Sequential Memory for verbal and non-verbal sounds and Dichotic Listening Test. Results The BAE revealed that 77.27% of the children presented normal hearing; 13.6% had conductive hearing loss and 2.2% presented mixed hearing loss. 21.2% of the children had type C tympanometry curve; 7.1% had a type B curve and 3.5% had an Ad curve. The APS was altered in 72.7% of the children and 45.5% of them presented altered results on the Dichotic Listening Test. Conclusion children with cleft lip/palate had altered results on BAE and APS, which justifies audiological and medical follow-up.
Identifying Extended Entity-Relationship Object Structures in Relational Schemas

Relational schemas consisting of relation-schemes, key dependencies and key-based inclusion dependencies (referential integrity constraints) are considered. Schemas of this form are said to be entity-relationship (EER)-convertible if they can be associated with an EER schema. A procedure that determines whether a relational schema is EER-convertible is developed. A normal form is proposed for relational schemas representing EER object structures. For EER-convertible relational schemas, the corresponding normalization procedure is presented. The procedures can be used for analyzing the semantics of existing relational databases and for converting relational database schemas into object-oriented database schemas. >
TIA Is Dead - Long Live TIA

A L E X M U R A W S K I SECURITY•Terrorism Information Awareness (TIA), a U.S. defense department program to mine credit card, medical, travel, police, and other governmental data, is being disbanded. Originally called Total Information Awareness, TIA got nothing but bad press because of its Orwellian name and mission. A joint House-Senate appropriations conference committee voted on 24 September to defund TIA through 2004, along with its bureaucratic parent, the Information Awareness Office, a branch of the Defense Advanced Research Projects Agency (Darpa) that Admiral John Poindexter had headed. But the committee allowed some programs to continue under different offices and agencies, a decision ratified on the House and Senate floors. The effect, ironically, will be to make some TIA programs less visible and less accountable. “Killing the Information Awareness Office is a positive first step,” says David Sobel, general counsel of the Electronic Privacy Information Center (Washington, D.C.), “but it doesn’t eliminate the government’s datamining initiatives. It drives them underground. ”
Formulation and in vitro Evaluation of Floating Capsules of Theophylline

Sustained release floating capsules for theophylline were fabricated using drug:polymer ratio of 30:70. The hydrocolloids were used in different proportions and four formulations were prepared. These formulations were optimized on the basis of buoyancy, matrix integrity, duration of floating and in vitro drug release. All the four formulations showed good buoyancy and matrix integrity. The duration of floating was more than 12 h for all formulations. In vitro drug release study of these formulations indicated controlled release of theophylline and about 76 percent drug was released at the end of 12 h.
