An Interior-Constraint BEM for Regularization of Problems with Improper Boundary Conditions

A well-posed problem in analysis of elastic bodies requires the definition of appropriate constrains of the boundary to prevent rigid body motion. However, one is sometimes presented with the problem of non-self-equilibrated tractions on an elastic body that will cause rigid body motion, while the boundary should remain unconstrained. One such case is the analysis of multi-particle dynamics where the solution is obtained in a quasi-static approach. In such cases, the motion of the particles is governed by the dynamic equilibrium while the contact forces between particles may be computed from elastostatic solutions. This paper presents two regularization methods of Interior-Constraint Boundary Element techniques for elastostatic analysis with improper boundary supports. In the proposed method rigid body modes are eliminated by imposing constrains on the interior of an elastic body. This is accomplished through simultaneously solving the governing Boundary Integral Equation and Somigliana’s Identity. The proposed method is examined through assessment and verification studies where it is demonstrated, that for all considered problems rigid body motion is successfully constrained with minimal effects on body deformations.
RETRACTED: Study on Development of Novel Mg-Based Alloys by Rapid Solidification Technology of Twin Roll Casting

In this study, Mg-based alloys were prepared by rapid solidification of twin roll casting (TRC), then microstructure and element distribution were investigated respectively with Scanning Electron Microscope (SEM) and Electron Probe Micro Analyzer (EPMA). What’s more, in order to analyze microstructure and crystal structure of Mg-based alloys, experiments on specimens with the usage of X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) were also carried out. At last, the designed Mg-Re magnesium alloy with quasi-amorphous phase plus fine crystalline phase dual phase microstructure produced with our rapid solidification of TRC process. The rapid solidification process realized with a faster casting speed and a thinner roll gap that does not need any anther additional devices and vacuum environment. EPMA results and TEM analyses show that the quasi-amorphous phase has a high concentration in Al and RE element. There are quasi-amorphous phase in the middle of Mg-Re alloy cross section surrounded by dendrites phase and normal crystals. Acknowledgement.

What drives child health improvements in Indonesian households? A micro-level perspective on complementarities in MDG achievements

Using panel data from Indonesia, this paper analyzes the linkages between child nutrition, health care, household wealth and parental education in order to detect transmission channels between health, education, nutrition, water and sanitation access, five critical MDG targets. This paper therefore also aims at providing an empirical analysis of the drivers of complementarities between these goals at the micro level micro-level perspective. We find that maternal education has a positive and long term effect on child health and that this effect is partly reflected in reproductive behavior and partly conveyed to child health outcomes through child caring practices such as breastfeeding. Although we cannot rule out the existence of strong complementarities existing between household wealth or income and child health, the effect of positive changes in this variable appears to be present only in the short term. On the other hand, there are supply-side factors such as lack of sanitation and access to health facilities which also strongly affect children in terms of anthropometric outcomes.
Feedback type as a moderator of the relationship between achievement goals and feedback reactions

The aim of the current study is to shed new light on the inconsistent relationship between performance-approach (PAp) goals and feedback reactions by examining feedback type as a moderator. Results of a field experiment (N = 939) using a web-based work simulation task showed that the effect of achievement-approach goals was moderated by feedback type. Relative to individuals pursuing mastery-approach goals, individuals pursuing PAp goals responded more negatively to comparative feedback but not to task-referenced feedback. In line with the hypothesized mediated moderation model, the interaction between achievement goals and feedback type also indirectly affected task performance through feedback reactions. Providing employees with feedback is a key psychological principle used in a wide range of human resource and performance management instruments (e.g., developmental assessment centres, multi-source/360 degrees feedback, training, selection, performance appraisal, management education, computer-adaptive testing, and coaching). The current study suggests that organizations need to strike a balance between encouraging learning and encouraging performance, as too much emphasis on comparative performance (both in goal inducement and in feedback style) may be detrimental to employees' reactions and rate of performance improvement.
Assessment of endothelial function in relation to the presence of type 2 diabetes mellitus in patients with prior myocardial infarction: a pilot study using peripheral arterial tonometry

Background. Endothelial dysfunction represents an early stage of atherosclerosis, while hyperglycaemia remains an important cause of endothelial dysfunction. The aim of this study was to assess endothelial function in patients with prior ST-segment elevation myocardial infarction (STEMI) in relation to the presence of type 2 diabetes mellitus (DM). Materials and methods: Eighty three adults treated with primary percutaneous intervention for STEMI within the previous 12–18 months were enrolled in a case-control study. The control group consisted of 21 healthy volunteers. Endothelial function was assessed with peripheral arterial tonometry (PAT). The value of reactive hyperemia index (RHI) and the presence of endothelial dysfunction (defined as RHI ≤ 2.0) were respectively the primary and secondary study endpoints. Results. RHI was significantly lower in post-STEMI subjects with concomitant type 2 DM (n = 21) than in healthy volunteers [1.70 (1.44–1.96) vs 2.15 (1.82–2.50); p = 0.006]. On the other hand, there were no significant differences in RHI between post-STEMI patients with and without type 2 DM [n = 62; RHI: 1.87 (1.59–2.39)], nor between the latter group and the control group. In terms of the secondary study endpoint, we observed a decreasing prevalence of endothelial dysfunction across the compared groups [76.2% vs 54.8% vs 38.1% for post-STEMI diabetics, post-STEMI non-diabetics and controls, respectively; p for trend = 0.013]. Conclusions. Our study indicates that endothelial function assessed with PAT is significantly worse in post-STEMI subjects with concomitant type 2 DM compared to healthy controls, but it does not seem to be substantially different in diabetic vs. non-diabetic STEMI survivors. The clinical significance of our findings warrants further investigation in adequately powered, prospective studies.
Lean Supply Chain Decisions Implications for Construction in a Developing Economy

Construction in developing economies is now a vital sector that contributes more than a marginal growth to the economic emancipations of countries in sub-Sahara Africa, South America and Asia. The upswing in construction activities tends to increase the number of actors that must make decisions, which determine project outcomes. Thus, astute decisions are critically important for project success. This paper addresses how lean supply chain decisions engender project value in the sector. Qualitative approach in the form of “structured literature review” led to the primary data that were generated. Using lean ‘general management’ and ‘construction management’ as the subject area, supply chain decisions were examined in the literature. The increased number of stakeholders, especially at the operational phase of project execution necessitates the negotiation of improved collaborative working within the supply chain. The interfaces between suppliers, subcontractors and contractors imply that supply chain decisions affect the finished product. These interfaces may either accelerate or decrease the rate of production on sites. The enhancement of how supply chain decisions are made and the ‘quality’ of such decisions could drive out / reduce wasteful activities, and then ensure that the finished product achieve expected ends. This discourse contributes to management related initiatives that are already on-going in the industry, especially as it affects developing economics.
EXPLORING THE POWER OF FREQUENT NEIGHBORHOOD PATTERNS ON EDGE WEIGHT ESTIMATION

Since links on social networks model a mixture of many factors, such as acquaintances and friends, the problem of link strength prediction arises: given a social tie e = (u, v) in a social network, how strong the tie e is? Previous work tackles this problem mainly by node profile-based methods, i.e., utilizing users’ profile information. However, some networks do not have node profiles. In this thesis, we study a novel problem of exploring the power of frequent neighborhood patterns on edge weight estimation. Given a labeled graph, we estimate its edge weights by applying its structural information as features. We develop an efficient pattern-growth based mining algorithm to mine frequent neighborhood patterns as features to estimate edge weights. Our experimental results on two real datasets show the efficiency of our method and the effectiveness of the frequent neighborhood pattern based features.

Chromatographic lipophilicity and pharmacokinetic behavior of some newly synthesized styryl lactone stereoisomers

The RP-HPLC retention constants of several newly synthesized cytotoxic styryl lactone stereoisomers were determined as parameters of their lipophilicity. Stereochemistry of the compounds has an effect on the retention behavior of only tricyclic isomers. For them, the difference in retention and chromatographic lipophilic parameters are significant. The chromatographic lipophilic parameters of all compounds were correlated with a fourteen computer calculated lipophilic parameters, log P, and pharmacokinetic parameters. Significant linear correlations (Radj>0.90) were obtained between MLog P and affinity for plasma proteins binding. The correrelations for the other pharmacokinetic parameters were improved by introducing some more molecular descriptors. Multiple linear regression analysis suggested that the volume of distribution depended on the lipopholicity and Ka (HSA-human serum albumin) and the absorption through membrane and permeability in the jejunum depend on the lipophilicity and hydrogen bond donors. The tested compounds showed a potent to moderate cytotoxic activity toward several human cancer cells and poor permeation through the blood brain barrier.
Detecting Happiness in Italian Tweets: Towards an Evaluation Dataset for Sentiment Analysis in Felicittà

This paper focuses on the development of a gold standard corpus for the validation of Felicitta, an online platform which uses Twitter as data source in order to estimate and interactively display the degree of happiness in the Italian cities. The ultimate goal is the creation of an Italian reference Twitter dataset for sentiment analysis that can be used in several frameworks aimed at detecting sentiment from big data sources. We will provide an overview of the reference corpus created for evaluating Felicitta, with a special focus on the issues raised from its development, on the inter-annotator agreement discussion and on implications for the further development of the corpus, considering that the assumption that a single right answer exists for each annotated instance cannot be done in several cases in the particular kind of data at issue.
Ultrasonic Guided Waves in Piezoelectric Layered Composite with Different Interfacial Properties

Combining the propagation model of guided waves in a multilayered piezoelectric composite with the interfacial model of rigid, slip, and weak interfaces, the generalized dispersion characteristic equations of guided waves propagating in a piezoelectric layered composite with different interfacial properties are derived. The effects of the slip, weak, and delamination interfaces in different depths on the dispersion properties of the lowest-order mode ultrasonic guided wave are analyzed. The theory would be used to characterize the interfacial properties of piezoelectric layered composite nondestructively.
‘You have to understand words … but not read them’: young children becoming readers in a digital age

Given that many young children now enter their early years in education as competent and frequent users of digital technology, this paper examines how this experience influences children’s perceptions of reading. Drawing from research conducted with 12 young children (aged 3‐6) this paper reports on the ways in which these children were interacting with screen texts and using them to develop strategies to make sense of a whole variety of symbolic representations, including print. It is argued that the medium of computer technology in particular was seen to encourage young children to develop both understandings about texts and the skills needed to read them. This included specific aspects of print awareness as well as a general confidence in handling print. However, this confidence appeared to diminish as the children encountered ‘schooled’ approaches to print literacy. It is therefore concluded that schools need to find ways in which to capitalise on the use of multimedia in order to promote confidence and skills in young readers today.
Streamflow increase due to rupturing of hydrothermal reservoirs: Evidence from the 2003 San Simeon, California, Earthquake

Following the Mw = 6.5 San Simeon, California, earthquake on December 22, 2003, USGS stream gauges documented two consecutive increases in streamflow in the Salinas River and Lopez Creek in the central Coast Ranges. The first increase occurred within 15 minutes after the earthquake and lasted about an hour; the second one occurred a few hours later and lasted much longer. Evidence and simulation suggest that these increases were caused by earthquake‐induced rupturing of pressurized hydrothermal reservoirs.
Radio continuum observations of new radio halos and relics from the NVSS and WENSS surveys - Relic orientations, cluster X-ray luminosity, and redshift distributions

Radio halos and relics are diffuse radio sources found in galaxy clusters showing significant substructure at X-ray wavelengths. These sources provide important information about non-thermal processes taking place in the ICM. Until now only a few dozen relics and halos are known, while models predict that a much larger number of these sources exist. In this paper we present the results of an extensive observing campaign to search for new diffuse radio sources in galaxy clusters. We discovered 6 new radio relics, including a probable double relic system, and 2 radio halos. In addition, we confirm the presence of diffuse radio emission in four galaxy clusters. By constructing a sample of 35 radio relics we find that relics are mostly found along the major axis of the X-ray emission from the ICM, while their orientation is perpendicular to this axis. This is consistent with the scenario that relics trace merger shock waves. The major and minor axis ratio distribution of the ICM for clusters with relics is also broader than that of the NORAS-REFLEX sample. We compared the X-ray luminosity and redshift distributions of clusters with relics to an X-ray selected sample from the NORAS and REFLEX surveys. We find tentative evidence for an increase of the cluster's relic fraction with X-ray luminosity and redshift. [abridged]
Legitimating Business Activities Using Corporate Social Responsibility: Is there a Need for CSR in Agribusiness?

result, enterprises in the agribusiness sector are increasingly exposed to the public eye (Jansen/ Vellema: 2004). The perception of consumers and other stakeholders - which are according to Freeman “any group or individual who can affect, or is affected by, the achievement of the organization’s objectives” - is of growing criticism and risk-consciousness and manifests itself in changed attitudes towards food production (Jackel/Spiller: 2006; Haddock: 2005). The use of GMO in agriculture, e.g., is regarded to be morally reprehensible (Becker: 1999). The BSE-crisis and other food scares led to growing consumer uncertainty and resulted in decreased meat consumption and in the increasing percentage of outspoken vegetarians and low-meat consumers (von Alvensleben: 1997; Staack: 2005). Moreover, the influence capacity of stakeholders is growing (Gerlach: 2006). As a result these factors have reduced the legitimacy of traditional (e.g., animal production) as well as new production technologies (e.g. bioenergy) in the agribusiness. In the long term the success of enterprises in the agribusiness can be affected by legitimacy losses. Against this background, legitimacy is regarded as a resource that guarantees the long-term survival of an enterprise (Palazzo/Scherer: 2006). Primarily the market based view in general management literature and the macro-institutional approach in neo sociological-institutionalism are employed to understand business operations embedded in societal structures. In this context legitimacy means the conformation of an organization with social norms, values and expectations (Oliver: 1996).
Notes on the distribution and habitat of Ochthebius lobicollis Rey, 1885, a poorly known north-western Mediterranean coastal species (Coleoptera: Hydraenidae)

Ochthebius (Ochthebius) lobiccoastal habitatsollis Rey, 1885 is recorded for the first time from the Iberian Peninsula (Girona) and the island of Corsica; new records are also given for the islands of Menorca and Sardinia. The species is known only from coastal habitats through the Gulf of Lion and the Ligurian and Balearic seas, typically living in rockpools of different salinity or small trickles or freshwater runoffs. Genetic data of the cytochrome oxidase 1 gene from Iberian, Menorcan and Sardinian specimens shows less than 1% divergence, suggesting lack of isolation between populations.
MORPHOMETRIC STUDY OF THE LUMBAR VERTEBRAL PEDICLE IN MAHARAHTARIAN POPULATION

The pedicle a thick and strongest part of vertebrae is being used for the implantation or fixation of screw (Transpedicular screw fixation) in various spinal problems like fracture of lumbar spine, resection of tumours in vertebral bodies or deformity of vertebral column. However, the success of technique depends on the factors like choice of size of screw for a particular pedicle size and shape. Pedicle screw has its own disadvantage because mismatched size of screw and pedicle instrumentation may fail. For this reason, study of morphometry of pedicles is of special significance as dimensions of pedicle become pivotal information for selection of screw in fixation. In the present study comprehensive morphometric measurements have been taken and an attempt is made to look into all the dimensions of pedicle. Internal and external pedicle diameter measurements give us the exact idea about available thickness of outer cortical and inner cancellous bony part of pedicle. METHODS: The present study Twenty five vertebral columns were procured from the cadavers from Department of Anatomy of Dr. D. Y. Patil Medical College Pimpri, Pune. The cadavers were embalmed and fixed by 10% formalin solution. Normal vertebral columns were included in the study. Gross abnormalities such as scoliosis, kyphosis and pathological vertebrae were excluded. Cadavers were numbered from 1-25 at random. Gender differentiation was not done. Comprehensive dimensions which included pedicle width, pedicle height, internal pedicle height (IPDH) and internal pedicle width (IPDD) diameters were measured using vernier calipers. Statistical mean, standard deviation and range were obtained. Results were tabulated and analyzed. RESULT: In the present study Pedicle height was maximum at L1 (mean 15.2±1.7, range: 12.5 to 18.8) vertebra. Pedicle width increase from L1 (mean 8.2±2.4, range 4.8to16.5) to L5 (mean: 18.4±2.2, range 13 to 22). Internal height gradually increase from L2 to L5 on both sides, and then it increased onL1, on left side. Internal width showed a gradual increase from L1 (mean: 5.4±1.5) to L5 (mean: 8.9±1.9).
Modelling tropical cyclone disturbance of the Great Barrier Reef using GIS

Tropical cyclones periodically cross the Great Barrier Reef (GBR). Physical damage from the large waves they generate can significantly alter coral reef community structure over time. Yet cyclone disturbance of the GBR has not yet been examined for more than a few events and for only part of the region. Meteorological models can be used to hindcast the likely magnitude and distribution of cyclone energy from the Australian Bureau of Meteorology's tropical cyclone database. This hindcast energy, along with measures of the spatial patterning of reefs, can be linked statistically to field observations of reef impact to predict the distribution of cyclone impacts on areas not surveyed. Implementing the requisite meteorological and spatial models within a GIS has made it feasible to apply these techniques over a longer time period (3 decades) and across a larger area (the entire GBR) than has been done before. The resultant cyclone history can be used to examine the degree to which broad measures of current reef community structure (dominant size classes and growth forms) can be explained by cyclone disturbance alone. This paper will demonstrate these modelling techniques using cyclone Joy (1990) as a case study.
Marital adjustment across the transition to parenthood: The role of communication and personality

Past research on the transition to parenthood has consistently found that this life phase results in many changes in a couples’ marital relationship, specifically declines in couples’ marital adjustment. This study was designed to investigate the relationship between constructive communication, personality traits, and spouses' marital adjustment during the transition to parenthood. Participants were 70 married couples expecting their first child. Self-report measures were administered to all participants during the third trimester of pregnancy, three months postpartum, and nine months postpartum. Results showed that marital adjustment significantly declined during the transition to parenthood. Constructive communication consistently correlated significantly with marital adjustment but was not a good predictor of changes in marital adjustment. Husbands' neuroticism, conscientiousness, and agreeableness consistently correlated significantly with both husbands' and wives' marital adjustment, but only agreeableness was a consistent predictor of changes in marital adjustment across the transition to parenthood. No support was found for the hypothesis that constructive communication mediates the relationship between personality and marital adjustment.
