Susceptible-infected-removed (SIR) model of crisis spreading in the correlated network of listed companies and their main stock-holders

According to the annual reports of listed companies,a correlated network of the listed companies and their main stock holders are established.Taking into account the mutual influences,resulted from reduced cash flows or the fracture of capital chain,between the listed companies and the main stock holders,a susceptible-infected-removed model of crisis spreading(SIR) in the stock markets is established.Then,a numerical computation is used to analyze the crisis spreading in the correlated networks when the networks meet the random failure or the intentional attacks.If there are some failures or attacks on the large-scale listed companies or large-scale holding companies(Hub vertices) in the networks,the crisis will spread in a high speed and cause catastrophic damages.In this condition,the networks show a obvious vulnerability;and the stock markets may show domino effects.The research approaches in this paper are helpful for further researches on the transmission mechanism of the economic crisis.
Relationships between bank customers’ risk attitudes and their balance sheets

This paper analyzes relationships between Swedish bank customers’ risk appetite and their financial assets and debt, controlling for demographic, socio-economic, financial and educational variables including financial literacy. We use subjective risk measures, i.e. risk tolerance and risk preference, as well as an objective risk measure, i.e. relating customers’ saving deposits to more risky stocks and mutual funds as a share of total financial assets. Bank customers with high risk appetite have significantly more financial assets compared with those with medium and low risk appetite. The subjective risk measures show that those with high risk appetite have significantly higher debt than those with low risk appetite. The objective risk measure shows the opposite. The paper concludes that it is important to use several measures of risk. Also, policy makers and banks need to measure bank customers’ risk appetite in a more systematic and transparent way, in order to improve both the banks’ and their customers’ risk management, and not less importantly, to decrease macroeconomic risks.
Solution of the canonical problem of an elementary dipole on a finite substrate using volume integral equations and volume physical optics

The far field behaviour of an elementary dipole on a one side cladded substrate is analysed as a canonical problem for the study of diffraction effects. The radiation pattern is calculated using three different methods: surface integral equations with multilayered Green's functions, volume physical optics (VPO) and volume integral equations (VIE). Although the finiteness of the substrate is taken into account by both VPO and VIE, these methods are inherently better suited for structures on large respectively small sized substrates. To our knowledge, comparison of VPO and VIE for such a medium sized structure is completely new. It allows us to establish approximate borders and an optimal application area for each method. The simulation results show good agreement. This validates the applicability of both methods for medium sized structures and is at the same time of great importance for estimation of the backward radiation intensity of more complex antenna structures
Corporate Initiatives In Indigenous Employment: The Australian Employment Covenant Two Years On

The Australian Employment Covenant (AEC) was launched on 30 October 2008 with the bold goal of creating 50,000 new jobs for Indigenous Australians within two years. At the end of this ambitious timeframe, the scheme has succeeded in securing more than 20,000 job pledges from employers. This is a commendable achievement, but estimates put the number of Indigenous job placements under the scheme at around 2,800, clearly well short of the original goal. The AEC has publicly backed away from its initial two-year timeframe and there has been some recent suggestion that its original target referred only to 50,000 job pledges. However, this is at best confusing, with public documents stating that the goals of the AEC initiative included the ‘placement of 50,000 Indigenous people into work’. This paper examines the nature of the AEC and its relationship with government as well as exploring why the rate of actual job creation might have been much lower than anticipated. It first sets out the scale of the challenge entailed in creating 50,000 new jobs for Indigenous Australians, with data suggesting that this was always an impossibly ambitious goal. It then examines outcomes in three areas: the number of jobs pledged; estimates of the number of job placements; and estimates of retention rates to 26 weeks. A key point to note is that available evidence has been very limited, making any assessment of the efficiency of government spending impossible and raising important questions about accountability and transparency in the expenditure of public funds. The paper concludes with a discussion of some of the factors likely to be constraining Indigenous labour supply. It argues that while the AEC may add value to existing employment programs—particularly by securing increased employer demand for Indigenous workers—a more flexible approach to employment services might prove more effective in increasing sustainable employment outcomes among Indigenous people.
Global Spillovers into Domestic Bond Markets in Emerging Market Economies

While fiscal conditions remain healthier than in advanced economies, emerging economies continue to be exposed to negative spillovers if global conditions were to become less favorable. This paper finds that domestic bond yields in emerging economies are heavily influenced by two international factors: global risk appetite and global liquidity. Using a novel approach, the analysis goes on to show that the vulnerability of emerging economies to these factors is not uniform but rather depends on country specific characteristics, namely fiscal fundamentals, financial sector openness and the external current account balance.
HDclassif: an R Package for Model-Based Clustering and Discriminant Analysis of High-Dimensional Data

This paper presents the R package HDclassif which is devoted to the clustering and the discriminant analysis of high-dimensional data. The classification methods proposed in the package result from a new parametrization of the Gaussian mixture model which combines the idea of dimension reduction and model constraints on the covariance matrices. The supervised classification method using this parametrization is called high dimensional discriminant analysis (HDDA). In a similar manner, the associated clustering method is called high dimensional data clustering (HDDC) and uses the expectation-maximization algorithm for inference. In order to correctly fit the data, both methods estimate the specific subspace and the intrinsic dimension of the groups. Due to the constraints on the covariance matrices, the number of parameters to estimate is significantly lower than other model-based methods and this allows the methods to be stable and efficient in high dimensions. Two introductory examples illustrated with R codes allow the user to discover the hdda and hddc functions. Experiments on simulated and real datasets also compare HDDC and HDDA with existing classification methods on high-dimensional datasets. HDclassif is a free software and distributed under the general public license, as part of the R software project.
Phylogenetic analysis of flatfish (Order Pleuronectiformes) based on mitochondrial 16s rDNA sequences

SUMMARY: The phylogenetic relationships of the order Pleuronectiformes are controversial and at some crucial points remain unresolved. To date most phylogenetic studies on this order have been based on morpho-anatomical criteria, whereas only a few sequence comparisons based studies have been reported. In the present study, the phylogenetic relationships of 30 flatfish species pertaining to seven different families were examined by sequence analysis of the first half of the 16S mitochondrial DNA gene. The results obtained did not support percoids as the sister group of pleuronectiforms. The monophyletic origin of most families analyzed, Soleidae, Scophthalmidae, Achiridae, Pleuronectidae and Bothidae, was strongly supported, except for Paralichthyidae which was clearly subdivided into two groups, one of them associated with high confidence to Pleuronectidae. The analysis of the 16S rRNA gene also suggested the monophyly of Pleuronectiforms as the most probable hypothesis and consistently supported some major interfamily groupings.
Post thrombotic syndrome following deep vein thrombosis in paediatric patients

Background Although well characterised in adults, less is known about post-thrombotic syndrome in children. In this review, current knowledge regarding paediatric post-thrombotic syndrome is summarised, with particular emphasis on pathophysiology, aetiology, diagnosis and management. Methods A Medline literature review was performed using search terms ‘post thrombotic syndrome’, ‘post phlebitic syndrome’, paediatric and children. Relevant articles were identified and included for summation analysis. Results The incident of paediatric venous thromboembolism is rising. Deep vein thrombosis can cause venous hypertension through a combination of venous reflux, venous obstruction and impairment of the calf muscle pump, leading to development of post-thrombotic syndrome. In children, this is more likely to occur if deep vein thrombosis diagnosis and treatment are delayed, if a higher number of vessels are involved, and if factors such as D-dimer are elevated at diagnosis and throughout treatment. Post-thrombotic syndrome occurs in about 26% of paediatric deep vein thrombosis, though the results of individual studies vary widely. A number of tools exist to diagnose paediatric post-thrombotic syndrome, including the modified Villalta scale and Manco-Johnson instrument. Once post-thrombotic syndrome develops, the mainstay of treatment remains supportive, with little evidence of benefit from pharmacological measures. Conclusion Surgical or interventional treatment is not advised except in exceptional cirumstances, due to variable prognosis of PTS in paediatric populations with rising incidence of paediatric venous thromboembolism, it follows that the prevalence of post-thrombotic syndrome in children may also increase. Evidence-based venous thromboembolism prevention strategies need to be implemented for prevention of deep vein thrombosis, but when it does occur, deep vein thrombosis requires prompt and effective treatment to prevent post-thrombotic syndrome. Optimum treatment strategies for post-thrombotic syndrome require further investigation.
A generalized method for the calculation of TLM dispersion relations

A generalized algebraic method for the calculation of TLM dispersion relations is presented. The method can be applied to general TLM nodes described by square scattering and propagation matrices of equal dimension. To demonstrate the method, the dispersion relations of the scalar TLM node and of the three-dimensional condensed symmetric TLM node are calculated.
Freight Forwarding Outsourcing and Supply Chain Efficiency among Manufacturing Firms in Uganda: The Case of Mukwano Industries Ltd.

This article examines the influence of freight forwarding outsourcing on supply chain efficiency. Specifically, the paper analyses the influence of freight forwarding outsourcing decision making, planning and administration on supply chain efficiency in Mukwano Group of Companies. The researchers employed case study and cross sectional designs, which used the researchers’ made questionnaire and interview guide for data collection. Data was analyzed using means, correlations and regression models computed using the Statistical Package for Social Scientist (SPSS). Finding revealed that freight forwarding outsourcing does not influence supply chain efficiency, owing to supplier profit margins, supplier deficiencies in the human resource composition, and neglect of the strategic dimension in outsourcing, among others. The researchers therefore recommend that, outsourcing initiatives should emphasize outsourcing planning and administration in a strategic dimension and consider inter-organizational mapping to identify areas of complementation and cohesion within the outsourcing relationship. Strategies like partnerships and outright acquisitions can also be explored.
A refinement and validation of the MARKOR scale

In this article, the authors attempt to develop an improved market orientation scale built on Kohli, Jaworski, and Kumar’s market orientation scale (MARKOR). The modified scale is then compared with the MARKOR scale in a validation study. The authors argue that the scale improves operationalization of the market orientation construct, and the results indicate that the psychometric properties of the new scale are superior to those of the MARKOR scale. Implications of the results are discussed, and a future research agenda is offered.
Centre and surround responses of marmoset lateral geniculate neurones at different temporal frequencies

The responses of marmoset lateral geniculate neurones to stimuli that were composed of a sinusoidally modulating centre stimulus and a surround that was modulated in counterphase were measured. The size of the stimulus centre was varied. These measurements were repeated at different temporal frequencies between 1 and 30 Hz. The response amplitudes and phases depended in a characteristic manner on the stimulus centre size. The response behaviour could be modelled by assuming Gaussian responsivity profiles of the cells' receptive field (RF) centres and surrounds and a phase delay in the RF surround responses, relative to the centre, enabling the description of RF centre and surround response characteristics. We found that the RF centre‐to‐surround phase difference increased linearly with increasing temporal frequency, indicating a constant delay difference of about 4.5 to 6 ms. A linear model, including low‐pass filters, a lead lag stage and a delay, was used to describe the mean RF centre and surround responses. The separate RF centre and surround responses were less band pass than the full receptive field responses of the cells. The linear model provided less satisfactory fits to M‐cell responses than to those of P‐cells, indicating additional nonlinearities.
The Role of Growth Factors on Renal Tubular Cells Submitted to Hypoxia and Deprived of Glucose

Background. In acute renal failure (ARF) renal tubular cell death and detachment can be induced by necrotic and apoptotic mechanisms. Several studies have demonstrated some benefits of the use of growth factors in experimental models of ARF. Methods. MDCK cells were cultured in a glucose-free medium for 24 h and were submitted to hypoxia (pO2 around 35 mmHg) for additional 24 h. To evaluate the possible protective role of growth factors, EGF, IGF-I or HGF were added to the medium (20 ng mL). LDH release, viability (acridine orange and ethidium bromide dyes) and quantification of apoptotic cells (Hoechst 33342 dye fluorescence) were determined. Results. In the injury group, an increase on LDH release (60% vs. 3%) and on number of apoptotic cells (22% vs. 0.2%) which was associated with a reduced cell viability (61% vs. 94%) when compared with controls. Only HGF, not EGF or IGF-I, was able to protect cells from injury. HGF caused a significant reduction on LDH release (30%) and on number of apoptotic cells (5%), with an increase on viability cellular (79%). Conclusions. HGF decreases cell death on MDCK cells after hypoxic-induced injury, probably acting in both necrotic and apoptotic mechanisms.
Misidentification of Type of Lightning Flashes in Malaysia

The Lightning Detection System (LDS) system monitored by Malaysian Meteorological Service (MMS) and Tenaga Nasional Berhad (TNB) are not reliable that may due to unresolved site errors . From informal observation, Baharudin and co-workers found the data recorded by TNB was not identical to their data. In this paper,we observed about Lightning Flashes in Malaysia nearly 21 data matching the time and date of our data with data from TNB Reports that the lightning flash polarity between both data has a negative polarity, but there are differences on multiplicity. Regarding data from TNB Reports , they also noted that there was presented a total of 10 positive cloud-to-ground flash data , but we did not find any data positive cloud-to-ground flash data. However, the data we have found a total of 191 data were presented from cloud flash but TNB did not record any cloud flash.
Asymptomatic nodules over forearm and hand.

A 30-year-old milkmaid had asymptomatic 1.5-2.0 cms crusted nodules over her left forearm, right index (Figure 1) and right middle finger of two and an half weeks duration. She gave a history of similar lesions occurring over the teats of her cows three weeks back. The lesions had initially started as papules, which turned vesicular in four days time and were followed by crusting a week later. There was no evidence of fever or lymphadenopathy.
Selection of Nonstationary Dynamic Features for Obstructive Sleep Apnoea Detection in Children

This paper discusses the methodology for selecting a set of relevant nonstationary features to increase the specificity of the obstructive sleep apnea detector. Dynamic features are extracted from time-evolving spectral representation of photoplethysmography envelope recordings. In this regard, a time-evolving version of the standard linear multivariate decomposition is discussed to perform stochastic dimensionality reduction. For training aim, this work analyzes the concrete set comprising filter banked dynamic features that include spectral centroids, the cepstral coefficients as well as their time-variant energies. Performance of classifier accuracy is provided for the collected polysomnography recordings of 21 children. Moreover, since the apnea diagnosing is based on analysis of set of fragments partitioned from the photoplethysmography envelope recordings, a new approach for their indirect labeling is described. As a result, performed outcomes of accuracy bring enough evidence that if using a subset of cepstral-based dynamic features, then patient classification accuracy can reach as much as 83.3% value, when using a k-nn classifier, as well. Therefore, photoplethysmography-based detection provides an adequate scheme for obstructive sleep apnea diagnosis.

Cloned Cauliflower Mosaic Virus DNA Infects Turnips (Brassica rapa)

Cauliflower mosaic virus DNA cloned in the Sal I site of bacterial plasmid pBR322 infects turnip plants. The cloned viral DNA must be excised from the recombinant plasmid to infect, but need not be circularized and ligated in vitro. The cloned viral DNA lacks site-specific single-strand breaks found in DNA obtained directly from the virus. However, these breaks are reintroduced into the viral genome during multiplication of the virus in the plant host.
How does thinking in Black and White terms relate to eating behavior and weight regain?

This study explores the role of dichotomous thinking on eating behavior and its association with restraint eating and weight regain in a wide range of people. In a web-based survey with 241 adults, dichotomous thinking and behavioral outcomes related to eating (restraint eating, weight regain, body mass index, dieting) were assessed. Results showed that eating-specific dichotomous thinking (dichotomous beliefs about food and eating) mediates the association between restraint eating and weight regain. We conclude that holding dichotomous beliefs about food and eating may be linked to a rigid dietary restraint, which in turn impedes people’s ability to maintain a healthy weight.
