Theory of linear viscoelasticity of semiflexible rods in dilute solution

We present a theory of the linear viscoelasticity of dilute solutions of freely draining, inextensible, semiflexible rods. The theory is developed expanding the polymer contour about a rigid rod reference state, in a manner that respects the inextensibility of the chain, and is asymptotically exact in the rodlike limit where the polymer length L is much less than its persistence length Lp. In this limit, the relaxation modulus G(t) exhibits three time regimes: At very early times, less than a time τ∥∝L8/Lp5 required for the end-to-end length of a chain to relax significantly after a deformation, the average tension induced in each chain and G(t) both decay as t−3/4. Over a broad range of intermediate times, τ∥≪t≪τ⊥, where τ⊥∝L4/Lp is the longest relaxation time for the transverse bending modes, the end-to-end length decays as t−1/4, while the residual tension required to drive this relaxation and G(t) both decay as t−5/4. As later times, the stress is dominated by an entropic orientational stress, giving .

Clinical Presentations of Vitamin D Deficiency in Children at King Abdul-Aziz University Hospital, Jeddah, Saudi Arabia: A Cross-Sectional Survey

Objectives: This study assessed clinical presentations of vitamin D deficiency in Saudi Arabian children. Methods: This cross-sectional survey was conducted in the Paediatric Clinic at King Abdul-Aziz University Hospital in Jeddah from March to September 2015. This study included 371 healthy children, not known to have any medical illnesses between the ages of 2 and 18 years old discovered to have vitamin D deficiency. The families of the children were asked if they noticed any symptoms of vitamin D deficiency in their children. A diagnosis of vitamin D deficiency was made if blood tests found low levels of 25-hydroxyvitamin D, there is no other test done to them. Results: Of the population studied, 35 children had a past history of bone fractures, 70 had bone or joint pain, 55 had fatigue, 16 had depression, 28 experienced delayed teething, 7 had a bone deformity, 23 experienced delayed walking, 11 had delayed closure of fontanels, 5 had developmental delays, 4 exhibited rachitic rosary, 8 had bowing of the legs, 2 had kyphosis, and 71 children were asymptomatic. Conclusion: Joint pain was the most common presentation of the disorder followed by asymptomatic vitamin D deficiency in this population. So, routine screening for preschool children and adolescent is necessary to early detect and provide effective treatment.
Predicting Fluid Adherence in Hemodialysis Patients via the Illness Perception

PREDICTING FLUID ADHERENCE IN HEMODIALYSIS PATIENTS VIA THE ILLNESS PERCEPTION QUESTIONNAIRE REVISED by Tava L. Arnold The Illness Perception Questionnaire – Revised (IPQ – R; Moss-Morris, Weinman, Petrie, Horne, Cameron, & Buick, 2002) was utilized in the current research to better understand and predict fluid adherence in hemodialysis patients. A sample of patients was recruited from three hemodialysis centers in the Los Angeles area and 116 participants completed the Illness Perception Questionnaire – Revised. The Illness Perception Questionnaire – Revised (Moss-Morris, Weinman, Petrie, Horne, Cameron, & Buick, 2002), is based on the common sense model (CSM) of self regulation by Leventhal (1984). Fluid adherence was measured by the Interdialytic Weight Gain (IWG). IWG is determined by subtracting the postdialytic weight for the previous session from the predialytic weight for the current session. To obtain a more representative indicator of adherence over time the mean IWG was calculated over a 12 session period (approximately 4 weeks). Patients with a mean IWG weights over 2.5 Kg were considered non-adherent to fluid restrictions. In addition, a self-report demographic information questionnaire was administered. Block logistic regression demonstrated that non adherence to fluid restrictions accounted for 65% of the prediction equation and gender was the only identified variable as being a significant predictor of fluid adherence in this hemodialysis patient population. The results of this study suggested that patient illness perceptions as measured by the Illness Perception Questionnaire did not predict adherence to fluid restrictions. However, in this sample, women were significantly more likely to adhere to fluid restrictions than men. Possible modifications for future research, including a subjective measure of adherence as well as the objective measure are evaluated and discussed.

Effect of Domestic Capital Formation and Foreign Assistance on Rate of Economic Growth

It is universally recognized that income growth of a country is closely related to its rate of capital formation and foreign loans and assistance. This note attempts an empirical verification of this accepted fact based on a simple econometric study of the relationship between the rate of growth of per capita income of 58 developing countries and the per capita gross fixed capital formation and the per capita development assistance from developed countries. The results show that the effect of capital formation is not as great as is generally believed. Marginal output capital ratio is about 16 percent. The more surprising result is that forcing assistance has very small effect on per capita income. The paper lists several plausible explanation for this negligible effect of foreign assistance.
Family related transfers and child poverty across Europe

Welfare regimes across Europe differ considerably with respect to the support of and the policy instruments used to foster families with dependent children. In striving for a harmonization of social policy across EU-countries more insight in such cross-national differences is needed; this is especially true in light of the recent Eastern European extension of the EU. This paper adds to this research agenda by focusing on family related public cash transfers (FRT) and their relevance for alleviation of child poverty based on representative micro-data for 15 European countries.
More Calories or More Diversity? An econometric evaluation of the impact of the PROGRESA and PROCAMPO transfer programmes on food security in rural Mexico

This paper examines the PROGRESA and PROCAMPO cash transfer programs in Mexico and evaluates their impact on household food security and nutrition. These two programs differ in their gender targeting, with PROGRESA aimed at women and PROCAMPO generally at men, and program conditionality, with PROGRESA linked to development of human capital of children in the households and PROCAMPO linked to agricultural production. We try to answer the following questions. First, can a cash transfer program geared to agricultural production have the same impact on food security as a cash transfer program geared to consumption through purchases? Second, do eligibility requirements (gender of the recipient) and conditionality in the provision of cash transfers matter? Our results suggest that, contrary to conventional wisdom, men do not just drink away cash transfers and that monetary payments linked to a productive asset –land- can have as large or larger impact on food security as cash transfers not linked to a productive asset. We show that both programs boost total food consumption and caloric intake in similar proportions. However, PROCAMPO has a larger impact on meat and vegetables consumption and PROGRESA on the other food category. Furthermore, increased food security is achieved through different channels: PROGRESA through purchases while PROCAMPO through investment in home production. We also find that cash transfers linked to information on nutrition and health increase food diversity. PROCAMPO households that also receive PROGRESA, and the information that goes with it, are more likely to be eating a more varied diet than households that get PROCAMPO only. All this suggests that the choice of program design in terms of food security depends on objectives beyond total food consumption and caloric intake, such as consumption from specific food categories, food diversity, investment in agricultural production, and the degree of access to retail food markets.
Misrepresentation of Asset Quality and Financial Intermediation: Evidence from RMBS Market

We contend that buyers received false information about the true quality of assets in contractual disclosure by intermediaries during the sale of mortgages in the $2 trillion non-agency market. We construct two measures of misrepresentation of asset quality -- misreported occupancy status of borrower and misreported second liens -- by comparing the characteristics of mortgages disclosed to the investors at the time of sale with the actual characteristics of these loans at that time. About one out of every ten loans has one of these misrepresentations. These misrepresentations are not likely to be an artifact of matching error between datasets that contain actual characteristics and those that are reported to investors. At least part of this misrepresentation occurs within the boundaries of the financial industry (i.e., not by borrowers). The propensity of intermediaries to sell misrepresented loans increased as the housing market boomed, peaking in 2006. These misrepresentations are costly for investors, as ex post delinquencies of such loans are more than 60% higher when compared with otherwise similar loans. Lenders seem to be partly aware of this risk, charging a higher interest rate on misrepresented loans relative to otherwise similar loans. There is little evidence that these misrepresentations were priced in the securities at their issuance. A significant degree of misrepresentation exists across all reputable intermediaries involved in sale of mortgages. The propensity to misrepresent is unrelated to measures of incentives for top management or to quality of risk management inside these firms. Misrepresentations on just two relatively easy-toquantify dimensions of asset quality could result in forced repurchases of mortgages by intermediaries in upwards of $160 billion.

Spatial role labeling with convolutional neural networks

Many natural language processing applications require information about the spatial locations of objects referenced in text, or spatial relations between these objects in space. For example, the phrase a book on the shelf contains information about the location of the object book, corresponding to a trajector, with respect to the object shelf, which in turn corresponds to a landmark. Spatial role labeling concerns with the task of automatically processing textual sentences and identifying objects of spatial scenes and relations between them. In this paper, we describe the application of modern machine learning methods to extract spatial roles and their relations, specifically by adapting a pre-existing system based on a convolutional neural network architecture that has been recently proposed for the more general task of semantic role labeling. We report on experiments with datasets from the SemEval challenges on spatial role labeling, showing that our method can achieve results in line with the current state-of-the-art. We therefore argue that that spatial role labeling can leverage on recent developments in semantic role labeling, requiring only minimal adaptations.
Social Agglomeration Externalities

This paper examines social agglomeration externalities. Using survey data from the German Socio-Economic Panel, I examine the link between city size and different measures of consumption, social interaction and social capital. Further, using responses to satisfaction questions, I analyse whether individuals are compensated for diseconomies of agglomeration by positive agglomeration externalities in other areas. This equilibrium hypothesis cannot be rejected.
Calcium and Neurogenesis in Alzheimer's Disease

It was evidenced that impairment of calcium homeostasis is a potential mechanism in the development of Alzheimer's disease (AD). It remains, however, unclear how the calcium signaling are associated with in AD progression. Here we review recent studies to discuss the relationship among the signaling of intracellular calcium concentration, neurogenic activity, and AD progression. Analyzing these findings may provide new ideas to improve the neurogenic status in pathological processes in the aging brain.
Simultaneous Ascending Bid Auctions with Privately Known Budget Constraints

We study the impact of potentially binding liquidity constraints on the level of competition in a version of the simultaneous ascending bid auctions. We show that the possibility, even if arbitrarily small, of binding budget constraints can reduce competition significantly, because bidders can ‘pretend’ to be constrained, even if they are not. This effect can be significant: for many distributions of the bidders’ values, all unconstrained bidders behave as if they were liquidity constrained, even as the probability that bidders are budget constrained goes to zero. The possibility of budget constraints therefore requires special attention to the details of the auction. JEL classification number: D44 [H]
Validation of a Korean Version of the Insomnia Severity Index

Background and Purpose The purposes of this study were to standardize and validate a Korean version of the Insomnia Severity Index (ISI-K), and to evaluate its clinical usefulness. Methods We translated the ISI into Korean and then translated it back into English to check its accuracy. The 614 patients with sleep disorders who were enrolled in this study comprised 169 with primary insomnia, 133 with comorbid insomnia, and 312 with obstructive sleep apnea. All subjects underwent one night of polysomnography (PSG) and completed the Korean versions of both the Pittsburgh Sleep Quality Index (PSQI-K) and the Epworth Sleepiness Scale, as well as the ISI-K. The ISI-K was compared to these sleep scales and various PSG sleep parameters. Results The internal consistency the ISI-K total score was confirmed by a Cronbach's alpha of 0.92, and the item-to-total-score correlations (item-total correlations) ranged from 0.65 to 0.84, suggesting adequate reliability. The correlation between the ISI-K total score and PSQI-K was 0.84, which suggested adequate convergent validity. Low-to-moderate correlations were obtained between the ISI-K total score and PSG-defined sleep parameters: 0.22 for sleep onset latency, 0.38 for wake after sleep onset, and 0.46 for sleep efficiency. A cutoff score of 15.5 on the ISI-K was optimal for discriminating patients with insomnia. The test-retest scores over a 4-week interval with 34 subjects yielded a correlation coefficient of 0.86, suggesting excellent temporal stability. Conclusions The findings of this study show that the ISI-K is a reliable and valid instrument for assessing the severity of insomnia in a Korean population.
Strongly Secure Authenticated Key Exchange Protocol Based on Computational Diffie-Hellman Problem

Currently, there are a lot of authenticated key exchange (AKE) protocols in literature. However, the security proofs of this kind of protocols have been established to be a non-trivial task. The main issue is that without static private key it is difficult for simulator to fully support the SessionKeyReveal and EphemeralKeyReveal queries. Some proposals which have been proven secure either just hold in relatively weak models which do not fully support above-mentioned two queries or make use of the stronger gap assumption. In this paper, using a new technique named twin Diffie-Hellman problem proposed by Cash, Kiltz and Shoup, we present a new AKE protocol based on the computational Diffie-Hellman (CDH) assumption, which is more standard than gap Diffie-Hellman (GDH) assumption. Moreover, our scheme is shown to be secure in strong security definition, the enhanced Canetti-Krawczyk (eCK) model introduced by LaMacchia, Lauter and Mityagin, which better supports the adversaries’ queries than previous models.
Information systems research methodologies and models

The paper argues that one of shortcomings of majority of the current doctoral study programs in information systems is insufficient attention to research methodology. Information systems is an emerging scientific discipline and, consequently, it is still not obvious what amount of knowledge on research issues should be included in the doctoral study program. The paper discusses the body of knowledge in this field recommended for doctoral students in information systems. It is based on two years experience in teaching the module "Research principles and methods" for doctoral students in information systems field.
The Behavior of the Real Rate of Interest

In this paper we document real rate behavior. We do this by looking across a wide variety of constructed real rate series. These series are obtained by using a number of different methodologies for estimating expected inflation, using several different price series, and looking over different time periods. The evidence suggests that over the entire sample period, real rate increases follow output increases and the real rate is positively correlated with contemporaneous output. These results, however, are sensitive to the price series used. That is, we find evidence of specification uncertainty. We also find that real rate behavior varies over different sample periods.
EXPLAINING THE ORBITS OF THE GALACTIC CENTER S-STARS

The young stars near the supermassive black hole at the galactic center follow orbits that are nearly random in orientation and that have an approximately thermal distribution of eccentricities, N(<e) ∼ e2. We show that both these properties are a natural consequence of a few million years' interaction with an intermediate-mass black hole (IBH), if the latter's orbit is mildly eccentric and if its mass exceeds approximately 1500 solar masses. Producing the most tightly bound S-stars requires an IBH orbit with periastron distance less than about 10 mpc. Our results provide support for a model in which the young stars are carried to the galactic center while bound to an IBH, and are consistent with the hypothesis that an IBH may still be orbiting within the nuclear star cluster.
Determinants of Changes Dividend Behavior Policy: Evidence from the Amman Stock Exchange

The motivation for these studies is the international extensive researches about factors that might be important in determining firms dividend policy. There are many reasons explaining why dividend policy is so interesting. One reason is that the dividend policy of the firm affects its capital structure, since the retained earnings intent to fund the firm. Otherwise, the firm has to raise funds by issuing new debt. The behavior of dividend policy is the most debate able issue in the corporate finance literature and still keeps its prominent place both in developed and emerging markets. Dividend policy is one of the most intriguing topics in financial research. Even now, economists provide considerable attention and thought to solving the dividend puzzle, resulting in a large number of conflicting hypotheses, theories and explanations. This paper aims to determine the dividend policies of the 60 industrial firms listed on the Amman stock exchanges (ASE) for the period of 2005-2009, and to explain their dividend payment behavior. This study used the tobit regression analysis, and logit regression analysis, and hence the random effects tobit/logit models are favorable than the pooled models. The paper finds that the dividend policy in Jordan as a developing country is influenced by factors similar to those relating to developed countries.
LATE- TO POST-TECTONIC SETTING OF SOME MAJOR PROTEROZOIC ANORTHOSITE – MANGERITE – CHARNOCKITE – GRANITE (AMCG) SUITES

Recent zircon-based geochronological investigations in the Adirondack Mountains, in the state of New York, demonstrate that 1155 ± 6 Ma massif anorthosite was emplaced during the post-contractional phase (1160–1140 Ma) of the ca. 1200–1140 Ma Shawinigan orogeny. Emplacement of many other anorthosite – mangerite – charnockite – granite (AMCG) suites also correlates with the waning stage of orogeny and includes the ca. 1155 Ma Morin and Lac-Saint-Jean complexes, the ca. 1650 Ma Mealy Mountain complex, and the ca. 1450 Ma complexes of eastern Labrador. The correlation also applies to the ca. 930 Ma Rogaland anorthosite complex of Norway and the ca. 1060–1020 Ma late- to post-Ottawan anorthosites of central Quebec and the Appalachians of Virginia and southeastern Pennsylvania. These correlations suggest models involving delamination of overthickened orogenic lithosphere by foundering or convective removal, followed by asthenospheric ascent, and ponding of gabbroic melt at the crust–mantle interface. Orogen rebound following delamination results in stable, dynamically balanced settings in which gabbroic magma evolves slowly at high pressure to produce high-aluminum pyroxene and coarse, intermediate plagioclase characteristic of massif anorthosite. Related melting of the lower crust produces mangeritic and charnockitic magma. Ultimately, both anorthositic and granitic magmas ascend, and lower-pressure fractionation yields the classic AMCG suites. Transtensional reactivation of lithospheric-scale shear zones and old sutures also correlates with important AMCG magmatism and provides conduits for gabbroic magma that ponds at the crust–mantle interface or in the deep crust to produce AMCG suites. Flat-slab subduction, back-arc extension, slab breakoff, and hotspots represent alternative settings that can account for gabbroic underplating and fractionation resulting in AMCG suites, if consistent with geochronological constraints.
HPV Detection Methods

Given the causal relation between a persistent high-risk human papillomavirus (hrHPV) infection and the development of high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer, hrHPV testing has been advocated in addition to cytology for the detection of clinically relevant cervical lesions. HrHPV testing is thought to improve cervical screening algorithms, the management of women with cytologically equivocal smears, and the management of women treated for high grade CIN. In this chapter we discuss different methods for HPV detection and genotyping and their respective applications.
