Using scale invariance for wide-band frequency modeling of power systems

This paper presents a new wide-band frequency model based on scale invariance. Self-similarities observed in power systems are mathematically translated by power laws whose exponents are linked to spectral dimension. This parameter is an expression of the topological properties of the network. Power laws are used for obtaining a wide-band frequency dependent network equivalent. Application to an IEEE test distribution feeder is shown.
Methylome-wide association study of whole blood DNA in the Norfolk Island isolate identifies robust loci associated with age

Epigenetic regulation of various genomic functions, including gene expression, provide mechanisms whereby an organism can dynamically respond to changes in its environment and modify gene expression accordingly. One epigenetic mechanism implicated in human aging and age-related disorders is DNA methylation. Isolated populations such as Norfolk Island (NI) should be advantageous for the identification of epigenetic factors related to aging due to reduced genetic and environmental variation. Here we conducted a methylome-wide association study of age using whole blood DNA in 24 healthy female individuals from the NI genetic isolate (aged 24-47 years). We analysed 450K methylation array data using a machine learning approach (GLMnet) to identify age-associated CpGs. We identified 497 CpG sites, mapping to 422 genes, associated with age, with 11 sites previously associated with age. The strongest associations identified were for a single CpG site in MYOF and an extended region within the promoter of DDO. These hits were validated in curated public data from 2316 blood samples (MARMAL-AID). This study is the first to report robust age associations for MYOF and DDO, both of which have plausible functional roles in aging. This study also illustrates the value of genetic isolates to reveal new associations with epigenome-level data.
Individual Differences and Marketing Decision Support System Usage and Satisfaction

Relatively little is known about how managers interact with marketing decision support systems such as a computer simulation. The authors investigate individual difference variables to determine their role in influencing the utilization of and satisfaction with one component of a marketing decision support system. The research vehicle used is a computer simulation model for assisting decision making in retailing. The findings indicate that risk averseness, involvement, cognitive differentiation, and age are important predictors of utilization and satisfaction. Managerial implications of the findings are discussed.
Explaining customer satisfaction with complaint handling

Purpose – Due to the importance of understanding what circumstances make customer recovery programmes successful, this paper aims to study the effects of different cognitive evaluations (disconfirmation of expectations and perceived justice) and affective responses (positive and negative emotions) on satisfaction with complaint handling.Design/methodology/approach – The sample used in this study consists of 679 subjects who, over the last six months, had experienced service failures and had afterwards complained. The data were collected via personal interviews using a structured survey.Findings – The results of the study support the model and highlight the importance of the emotions experienced as a result of the complaint handling. Although these emotions have been underrepresented in the service recovery literature, our investigation shows that these emotions not only have an independent effect on customer satisfaction, after accounting for the effects of the cognitive evaluations of complaint handling,.
Financial Literacy, Households' Investment Behavior, and Risk Propensity

We investigate the role of socio-demographic characteristics of households on their level of self-declared financial literacy and investment experience, and the effect of financial literacy on household risk aversion, leveraging on about 38,000 MiFID questionnaires provided to us by an Italian primary bank. We find that the level of financial literacy is lower for the young and the old, women, less wealthy and financial fragile, lesseducated individuals living in the Southern part of Italy, and in less densely populated areas. Past professional expertise in a finance-related field helps increasing the level of financial literacy. Risk aversion of households is significantly affected by financial literacy, as the less financially knowledgeable tend to be more risk averse.
Estimation of the Maximal Lactate Steady State Intensity by the Rating of Perceived Exertion

The maximal lactate steady state is the gold standard for evaluating aerobic capacity; however, it is time-consuming. The lactate minimum protocol is an easier alternative, but is not feasible and still expensive. This study investigated whether the rating of perceived exertion of 13 is an accurate predictor of lactate minimum and maximal lactate steady state intensities. Eleven physically active men performed three tests: (1) incremental exercise with workloads based on rating of perceived exertion of 10, 13, and 16 (experimental protocol – denominated RPE-13 test), (2) lactate minimum, and (3) maximal lactate steady state. No differences were observed among participants’ workloads corresponding to rating of perceived exertion 13, lactate minimum, and maximal lactate steady state intensities. Thus, the workload associated with the rating of perceived exertion of 13 was equivalent to the other two protocols investigated.
Institutional Herding and Asset Price: The Role of Information

We study the price impact of daily institutional herding induced by information events. Using analyst recommendation changes as a proxy, we find that institutional herding on recommendation changes is short–lived. Daily institutional herding, on average, destabilizes price. However, herding accompanied by information arrival has the opposite effect. We find no evidence of price reversal when institutional investors herd in the direction of the recommendation change, but rather herding speeds up price adjustment. Consistent with informational herding models, we provide evidence that efficient price discovery and institutional herding are not mutually exclusive.
Criteria for Success in New Product Development for Consumer Goods: A Comparative Study

A very high proportion of new consumer products fail to reach their sales targets and are withdrawn. This is despite apparently rigorous and expensive testing procedures prior to launch. In this article the launch of two alcoholic beverage products in the UK is studied. One was a success while the other was a failure and the reasons for both cases are examined. What emerges is that it is dangerous to cut corners in the accepted testing techniques for new products.
Randomized trial of geragogy-based medication instruction in the emergency department.

BACKGROUND Medication adherence by older adults who are discharged from the emergency department (ED) is an essential attribute of effective treatment. Researchers have demonstrated that delivery of well-structured instructions increases the knowledge of discharge regimens and increases adherence among ED populations. OBJECTIVES This study compared the level of medication knowledge of elderly ED patients receiving instruction by one of two teaching methods: the usual preprinted discharge instructions with handwritten medication information and individualized computer-generated discharge instructions designed within a geragogy framework. METHOD The geragogy intervention included large-print, easily readable, specific information ordered within the elderly memory schema. This schema consists of purpose, administration, and emergency information in that order. The Knowledge of Medication Subtest by Horn and Swain (1977) was administered by telephone 48 to 72 hours after discharge. Sixty patients (38 women, 22 men) with a mean age of 76 years were randomly assigned to groups and completed the study at three rural ED sites. RESULTS Subjects in the geragogy-based intervention group demonstrated significantly more knowledge of medications than did subjects experiencing the usual discharge teaching method (t = 2.19, p = .016). CONCLUSIONS These findings suggest that a medication teaching intervention geared to the special needs of the elderly can be effective in increasing medication knowledge.
ITC'S E-CHOUPAL: A MARKETING STRATEGY FOR RURAL TRANSFORMATION - A CASE STUDY OF WARDHA DISTRICT, MAHARASHTRA

1This paper focus on increasing rural incomes through ICT led procurement is positioned as a way to unleash the latent demand for industrial and retail goods for fuelling the continued growth of the Indian economy. The economic development perspective lends weight for the creation of ecology the creation of ecology of strategic rural markets, where products and services are especially targeted towards improving agricultural value chains. Additionally fast moving consumer goods (FMCGs) banking and insurance services are routed through the ITC channel while quality retail product are provided at affordable prices with an accent on brand building. The study of e-choupal was conducted in the state of Maharashtra. Through e-Choupal procurement hubs and Choupal sagars (a kind of rural supermarket), information and products in urban centres are made available at the rural level thus reducing travel and time investments for rural populations especially for farmers. E-Choupal therefore seeks to leverage ICTs to integrate rural areas into large corporate markets and thus hopes to improve earnings as well as both the quantity and quality of consumption in rural areas.
Plasma estrogen, progesterone, and luteinizing hormone prior to estrus and during pregnancy in pigs.

Total estrogen, luteinizing hormone (LH), and progesterone concentrations were measured in plasma samples collected on days −6, −5, −4, −3, −2, −1 before estrus, estrus (day 0) and days 3, 6, 12, 18 and 24 of pregnancy in six gilts. The mean progesterone concentration decreased from 16.1 ng/ml of plasma (per pig) on day −6 before estrus to 1 ng/ml or less on day −4. Progesterone levels remained low through estrus, increased to a peak value of 35.4 ng/ml on day 12 of pregnancy, and then declined to 17.2 ng/ml on day 24. Total estrogen began to increase on day −3, which coincided with the time of lowest progesterone levels in most animals, and reached maximum values of about 38 pg/ml on days −2 and −1 before estrus. Prior to the proestrous peak and during pregnancy, levels of estrogen fluctuated between 10 and 28 pg/ml. There was a significant negative linear correlation (r = −0.369, n = 65) between ng of progesterone and pg of estrogen (p < 0.01) during the experimental period. LH values were the following.
Developing Country Interests in Liberalizing Manufactures Trade

The importance of manufactures trade to the developing countries has increased dramatically since the early 1980s, and developing countries’ reliance on each others as markets has also risen sharply. Developing countries face disproportionately high trade barriers in manufactures—relatively in the industrial countries, and absolutely in the developing countries—and barriers to their manufactures exports account for around 70 percent of the total barriers faced by their exports. The inclusion of manufactures trade in the WTO 2000 negotiations is particularly important for developing countries, who would benefit both from improved market access and through greater domestic efficiency. In fact, developing countries capture nearly all the benefits (95%) of manufacturing liberalization. In contrast, comparable cuts in agriculture and services benefit the high-income countries relatively more since only 27% and 30% of the global benefits accrue to developing countries in these two cases.
Daytime OIO in the Gulf of Maine

The potential importance of iodine for marine boundary layer (MBL) chemistry has found increasing recognition in recent years. However, observations of the key iodine species are sparse and the chemical reactions of the iodine oxides are not well understood. Here we present Differential Optical Absorption Spectroscopy observations of IO, OIO in the MBL of the Gulf of Maine, U.S., during Summer 2004. We report the first daytime observation of OIO, indicating that this compound is rather photostable. Mixing ratios of IO were similar to, and those of OIO higher than, values reported for European coastal sites. Calculations with the one‐dimensional model MISTRA show that the observed simultaneous presence of elevated OIO and NOx cannot be explained by currently known iodine chemistry. Our results lead to the conclusion that thus far unknown chemical reactions of iodine oxides, probably involving iodine nitrates, might occur in the MBL.
Residential Satisfaction with Private Housing Estate Development in Abuja-Nigeria

Residential Housing satisfaction studies have attracted the attention of researchers all over the world. This paper presents the result of housing satisfaction level with private residential estate development in Abuja, Nigeria. Four major Housing satisfaction components identified and measured includes: 1. Structural Components satisfaction 2. Dwelling Features satisfaction 3. Neighbourhood Facilities and environment satisfaction 4. Management services satisfaction. Data came from a structured questionnaire administered through a systematic random sampling technique to 112 occupants of Prince and Princes Housing Estate. Sixty six (66) questionnaires were successfully retrieved for analysis, yeilding about 74% response rate. Data were analyzed using descriptive statistics of the mean scores of satisfaction based on a five point likert scale. Result of the analysis indicates that residents have generally express low satisfaction with their Dwelling unit features. They are however, neither satisfied nor dissatisfied with the overall housing. The result of this research can be use as yard stick for development control monitoring parameters as well as policy guide in the developing countries in general, and Abuja in particular. It further compliments existing body of knowledge on housing satisfaction.
Supply chain replenishment: before‐and‐after EDI implementation

Purpose – This study seeks to determine whether electronic supply chains using electronic data interchange (EDI) are more successful than non‐electronic supply chains using manual (paper) purchase orders by analyzing the supplier‐manufacturer link in the SC.Design/methodology/approach – Identical products are analyzed before‐and‐after EDI implementation in an organization, therefore representing both electronic supply chain products and non‐electronic supply chain products.Findings – The empirical findings indicate that the EDI supply chain is more effective than the manual supply chain in terms of: shorter order cycles, greater availability, lower (purchase) price, and lower (transaction) cost.Originality/value – The present research study provides for a number of future research possibilities. First, the present research study focuses only on the supplier‐manufacturer link of the SC. Other links in the SC (manufacturer‐distributor, distributor‐retail outlet, and retail outlet‐customer) should be analyze.
Contractual governance, relational governance, and the performance of interfirm service exchanges: The influence of boundary-spanner closeness

Academics and managers are confronted with reconciling the social and economic aspects of business-to-business exchanges. In a service context, the authors investigate the relative importance of contractual and relational governance on exchange performance and the influence of the boundary spanner on the implementation of these governance mechanisms and on exchange performance. They test a model of the governance of commercial banking exchanges using interview data with both parties to the exchange (the account manager as the bank’s boundary spanner and the business client). Relational governance is the predominant governance mechanism associated with exchange performance. Contractual governance is also positively associated to exchange performance, but to a much lesser extent. The closeness of the account manager to the client company in terms of information gathering is also positively associated to exchange performance. However, this is mediated through both contractual and relational governance mechanisms with relational governance being the stronger mechanism.
The Autism Related Protein Contactin-Associated Protein-Like 2 (CNTNAP2) Stabilizes New Spines: An In Vivo Mouse Study

The establishment and maintenance of neuronal circuits depends on tight regulation of synaptic contacts. We hypothesized that CNTNAP2, a protein associated with autism, would play a key role in this process. Indeed, we found that new dendritic spines in mice lacking CNTNAP2 were formed at normal rates, but failed to stabilize. Notably, rates of spine elimination were unaltered, suggesting a specific role for CNTNAP2 in stabilizing new synaptic circuitry.
Effects of baseline and early acquired thrombocytopaenia on long-term mortality in patients undergoing percutaneous coronary intervention with bivalirudin.

AIMS Bivalirudin use as a procedural anticoagulant in patients undergoing percutaneous coronary intervention (PCI) is associated with a lower incidence of thrombocytopaenia compared to other antithrombotic agents. We aimed to evaluate the prognostic impact of baseline thrombocytopaenia and early changes in platelet counts among patients undergoing PCI with exclusive use of bivalirudin. METHODS AND RESULTS We evaluated 7,505 patients who underwent PCI over a period of eight years. Patients who received unfractionated heparin and glycoprotein IIb/IIIa receptor inhibitors were specifically excluded. Eight hundred and fifty-eight (11.4%) patients had baseline thrombocytopaenia and 451 (6.0%) developed acquired thrombocytopaenia. After adjustment for potential covariates, moderate to severe acquired thrombocytopaenia was the strongest independent predictor (HR 4.34, 95% CI: 2.13-8.84; p<0.001) of in-hospital net adverse clinical events, which included major adverse cardiac events and major bleeding complications. Age, male gender, baseline platelet count and intra-aortic balloon pump (IABP) insertion were independent predictors of in-hospital acquired thrombocytopaenia. After a mean follow-up of 2.6±1.7 years, moderate to severe baseline thrombocytopaenia (HR 2.42, 95% CI: 1.79-3.29; p<0.001), moderate to severe acquired thrombocytopaenia (HR 2.37, 95% CI: 1.13-4.97; p=0.02) and severe changes in platelet count (>67 k) were significant predictors of mortality. CONCLUSIONS In patients undergoing PCI with bivalirudin, moderate to severe baseline and acquired thrombocytopaenia along with severe changes in platelet count are associated with higher long-term mortality.
Evaluation of wound care and health-care use costs in patients with diabetic foot ulcers treated with negative pressure wound therapy versus advanced moist wound therapy.

BACKGROUND We conducted a post-hoc retrospective analysis of patients enrolled in a randomized controlled trial to evaluate overall costs of negative pressure wound therapy (NPWT; V.A.C. Therapy; KCI USA, Inc, San Antonio, Texas) versus advanced moist wound therapy (AMWT) in treating grade 2 and 3 diabetic foot wounds during a 12-week therapy course. METHODS Data from two study arms (NPWT [n = 169] or AMWT [n = 166]) originating from Protocol VAC2001-08 were collected from patient records and used as the basis of the calculations performed in our cost analysis. RESULTS A total of 324 patient records (NPWT = 162; AMWT = 162) were analyzed. There was a median wound area reduction of 85.0% from baseline in patients treated with NPWT compared to a 61.8% reduction in those treated with AMWT. The total cost for all patients, regardless of closure, was $1,941,472.07 in the NPWT group compared to $2,196,315.86 in the AMWT group. In patients who achieved complete wound closure, the mean cost per patient in the NPWT group was $10,172 compared to $9,505 in the AMWT group; the median cost per 1 cm(2) of closure was $1,227 with NPWT and $1,695 with AMWT. In patients who did not achieve complete wound closure, the mean total wound care cost per patient in the NPWT group was $13,262, compared to $15,069 in the AMWT group. The median cost to close 1 cm(2) in wounds that didn't heal using NPWT was $1,633, compared to $2,927 with AMWT. CONCLUSIONS Our results show greater cost effectiveness with NPWT versus AMWT in recalcitrant wounds that didn't close during a 12-week period, due to lower expenditures on procedures and use of health-care resources.
An analysis of referees and referrals to a specialist concussion clinic in New Zealand.

AIM This study reviews the characteristics of referrals to a specialist concussion clinic (Burwood Hospital Concussion Clinic, Christchurch, New Zealand) in its first two years of operation. METHOD Information regarding referral source, demographic and clinical features, time since mild traumatic brain injury (MTBI), assessment and treatment provided, service follow-up, and outcome at discharge were collected from a file search of all referrals received in the two years ending in October 2004. RESULTS Cases reflected the clinical and demographic diversity expected of those incurring an MTBI. Age and referral source were associated with failing to keep initial appointments. Assessments typically resulted in ongoing treatment from the service, although many were 'one-off' assessments. One-in-five cases resulted in ongoing treatment for more than 7 months. Gender, cause of MTBI, and time delay between injury and assessment were significantly associated with receiving long-term follow-up. Most cases had a good clinical outcome at discharge. CONCLUSIONS While the Concussion Clinic services the intended clinical population, referrals for assault-related MTBIs were greater than expected, and men may be under-referred. The disproportional number of non-attending patients referred from Christchurch Hospital Emergency Department along with the unanticipated proportion of cases receiving long-term follow-up, suggest a need for review of the referral response systems and the scope of service provision.
The Annotation Process in OpenStreetMap

In this article we describe the analysis of 25,000 objects from the OpenStreetMap (OSM) databases of Ireland, United Kingdom, Germany, and Austria. The objects are selected as exhibiting the characteristics of “heavily edited” objects. We consider “heavily edited” objects as having 15 or more versions over the object's lifetime. Our results indicate that there are some serious issues arising from the way contributors tag or annotate objects in OSM. Values assigned to the “name” and “highway” attributes are often subject to frequent and unexpected change. However, this “tag flip‐flopping” is not found to be strongly correlated with increasing numbers of contributors. We also show problems with usage of the OSM ontology/controlled vocabularly. The majority of errors occurring were caused by contributors choosing values from the ontology “by hand” and spelling these values incorrectly. These issues could have a potentially detrimental effect on the quality of OSM data while at the same time damaging the perception of OSM in the GIS community. The current state of tagging and annotation in OSM is not perfect. We feel that the problems identified are a combination of the flexibility of the tagging process in OSM and the lack of a strict mechanism for checking adherence to the OSM ontology for specific core attributes. More studies related to comparing the names of features in OSM to recognized ground‐truth datasets are required.
