Windage sources in smooth-walled rotating disc systems

Abstract This article presents experimental data and an associated correlation for the windage resulting from a disc rotating in air, characteristic of gas turbine engines and relevant to some electrical machine applications. A test rig has been developed that uses an electric motor to drive a smooth bladeless rotor inside an enclosed pressurized housing. The rig has the capability of reaching rotational and throughflow Reynolds numbers representative of a modern gas turbine. A moment coefficient has been used to allow a non-dimensional windage torque parameter to be calculated and an agreement with the relevant data in the literature has been found within 10 per cent. Infrared measurements have been performed that allow direct surface temperatures of the rotating disc to be obtained. Laser Doppler anemometry measurements have been made that allow velocities in the flow field of the rotor—stator cavity to be examined and tangential velocities corresponding to rotationally and radially dominated flow conditions are shown. The importance of the flow regime in relation to the resulting windage has been identified and in particular it is noted that windage is a function not only of the ratio of rotational and radial flow dominance as defined by the turbulence parameter, but also for a given value of the turbulence parameter, the magnitude of the rotationally induced and superimposed flows. The experiments extend the range of data available for windage in rotor—stator systems and have been used to produce a correlation suitable for applications operating up to the range of Reψ=107.
The Motivations of Domiciliary Care Providers in England: New Concepts, New Findings

The independent sector domiciliary care market has always been an integral part of the social care system in England, but has become especially important in recent years. Its smooth running is crucial for the delivery of an effective community care policy. This paper argues that the motivations of these providers is an important aspect of this system's functioning, and derives a typology which captures the most important ingredients which theory and practice suggest should be taken into account in this regard. Four provider types are identified; they can be labelled satisfied team players; demoralised isolates; ambivalence-experiencing go-getters; and ambivalence-experiencing quiet lifers. The categories reflect both the balance of intrinsic and extrinsic motivations, and these providers' situational contexts, including the nature of the relationships developed with local authority purchasers. The latter exert exceptional power and influence in social care markets in England.
Looking Tough: The Negotiator Under Constituent Surveillance

Constituent surveillance encouraged the negotiator's use of such competitive tactics as threats, positional commitments, and persuasive arguments. Negotiators apparently chose these tactics in order to look tough in the eyes of their constituent. These tactics resulted in diminished joint and individual outcomes. The results of the study suggest that constituents might fare better by not monitoring the behavior of their negotiators. Future research might profit by identifying the crucial intervening variables that account for the surveillance effects.

Key Drivers of Successful Implementation of an Employee Suggestion-Driven Improvement Program

Service organizations frequently implement improvement programs to increase quality. These programs often rely on employees’ suggestions about improvement opportunities. Organizations face a trade-off with such suggestion-driven improvement programs. On one hand, the improvement literature recommends that managers focus organizational resources on surfacing a large number of problems, prioritizing these, and selecting a small set of high priority ones for solution efforts. The theory is that soliciting a large number of ideas from employees will surface a set of higher priority problems than would have been identified with a less extensive search. Scarce organizational resources can be allocated to resolving the set of problems that provide the greatest improvement in performance. We call this an “analysis-oriented” approach. On the other hand, managers can allocate improvement resources to addressing problems raised by frontline staff, regardless of priority ranking. This “action-oriented” approach enables more resources to be spent on resolving problems because prioritization receives less attention. To our knowledge, this tradeoff between analysis and action in process improvement programs has not been empirically examined. To fill this gap, we randomly selected 20 hospitals to implement an 18-month long employee suggestion-driven improvement program; 58 work areas participated. Our study finds that an action-oriented approach was associated with higher perceived improvement in performance, while an analysis-oriented approach was not. Our study suggests that the analysis-oriented approach negatively impacted employees’ perceptions of improvement because it solicited, but not act on, employees’ ideas. We discuss the conditions under which this might be the case.
Inhibition of the Accelerative Effects of Testosterone on Hamster Facial Nerve Regeneration by the Antiandrogen Flutamide

We have previously demonstrated that systemic administration of testosterone propionate (TP) to adult hamsters accelerates the rate of facial nerve regeneration following crush axotomy of the facial nerve at its exit from the stylomastoid foramen. In this study, we utilized flutamide, a potent nonsteroidal antiandrogen, in conjunction with radioisotopic labeling procedures for the assessment of facial nerve regeneration rates to test the hypothesis that TP exerts its accelerative effects on facial nerve regeneration through a receptor-mediated mechanism. Castrated adult male hamsters were subjected to right facial nerve crush axotomies and divided into three groups of axotomized animals: castrate plus one subcutaneous TP implant plus daily injections of flutamide, castrate plus one subcutaneous TP implant plus vehicle injections, and castrate only plus sham implant and vehicle injections. There were two postoperative timepoints: 4 and 7 days. In agreement with previous studies, systemic administration of TP resulted in an approximately 26% increase in the rate of regeneration of the fastest growing population of axons. Exposure to flutamide completely abolished the TP-induced accelerative effects on facial nerve regeneration rate. As a bioassay for the effectiveness of systemic administration of flutamide by subcutaneous injection, seminal vesicle weights were collected from all groups at the end of the postoperative time and compared as a percentage of the seminal vesicle weights of intact (nongonadectomized) male control animals. Castration greatly reduced seminal vesicle weights, whereas exogenous TP restored the seminal vesicle weights to those of the intact male. Flutamide blocked the effects of exogenous TP on seminal vesicle weights and reduced them to castrate levels. (ABSTRACT TRUNCATED AT 250 WORDS)
How do people learn to allocate resources? Comparing two learning theories.

How do people learn to allocate resources? To answer this question, 2 major learning models are compared, each incorporating different learning principles. One is a global search model, which assumes that allocations are made probabilistically on the basis of expectations formed through the entire history of past decisions. The 2nd is a local adaptation model, which assumes that allocations are made by comparing the present decision with the most successful decision up to that point, ignoring all other past decisions. In 2 studies, participants repeatedly allocated a capital resource to 3 financial assets. Substantial learning effects occurred, although the optimal allocation was often not found. From the calibrated models of Study 1, a priori predictions were derived and tested in Study 2. This generalization test shows that the local adaptation model provides a better account of learning in resource allocations than the global search model.
Output synchronization for heterogeneous networks of non-introspective, non-right-invertible agents

We consider the output synchronization problem for a heterogeneous network of linear agents. The agents are non-introspective, meaning that they do not have access to their own state or output; the only information available to each agent comes from the network, in the form of a linear combination of its output relative to that of neighboring agents. The basis for our study is a design previously presented by the authors, which was based on an additional assumption requiring the agents to be right-invertible. Here we dispense with the assumption of right-invertibility and instead introduce a new assumption based on solvability of a particular set of regulator equations.
Homosexuality in Twins: A Family Study and a Registry Study

IN THIS PAPER, we will report briefly on a series of male twins where at least one of each pair was homosexual. One object is to report the number of concordant and discordant, monozygotic (MZ) and dizygotic (DZ) pairs observed. A second object is to examine the frequency of homosexuality in twins per se. One of the twin pairs was from a family deserving special attention. Among 14 siblings, there were three sets of male MZ twins. Two of these three sets of twins were concordant for homosexuality; in the remaining pair both twins were heterosexual. The results of our study of this family will be presented in detail. The use of twin studies as a means of disentangling some of the interaction of nature and nurture is sufficiently well known for it to be unnecessary to give any elaborate explanation here. 1,2 Briefly, differences in MZ pairs provide
Media logic in election campaign coverage

The media logic thesis holds that the content of political news is the product of news values and format requirements that media make use of to attract news consumers. This study tests whether three content characteristics – personalized, contest and negative coverage – manifest a single media logic by analysing whether they co-vary over time. It also tests the implicit assumption underlying the media logic thesis that media adhere to a single media logic as one institution. A semantic network analysis measured the degree to which television and newspaper coverage of five Dutch national election campaigns (1998–2010) contained the three content characteristics. The study shows that personalized, contest and negative coverage form three indicators of a single logic that is shared by different media. Since the turn of the century, Dutch political news has simultaneously become decreasingly personalized, less focused on the contest and less negative.
Energy efficient topology management for beyond next generation mobile broadband systems

This paper investigates suitable topology management strategies for a two-hop beyond next generation mobile broadband network, in order to substantially reduce energy consumption at low traffic levels. The energy model is introduced here. Several rules are proposed which are based on both traffic load and behaviour of adjacent nodes. A balance between energy saving and required Quality of Service (QoS) is considered. The results show our topology management strategies can substantially reduce energy consumption by up to 35-70% at low traffic loads compared with a deployment without topology management.
Inhibition of quorum sensing-controlled virulence factor production in Pseudomonas aeruginosa by Quercus infectoria gall extracts

Background and Objectives: This study was designed to evaluate the activity of Quercus infectoria galls extract (QIFGE) on virulence factor production and inhibition of quorum sensing (QS) in Pseudomonas aeruginosa. Materials and Methods: Minimum inhibitory concentration (MIC) of QIFGE against 5 strains of P. aeruginosa was determined. The extract at sub-MIC was used to determine biofilm formation, level of protease LasA, LasB, swarming and twitching motility and QS using Chromobacterium violaceum CV026 as a biosensor. Effect of the extract on expression levels of lasR gene was determined by real time PCR. Results: QIFGE inhibited the QS and all other tested virulence factors compared with the control grown in the absence of the extract (P=0.001). Real time PCR showed 2 to 8-fold reduction in lasR gene expression in presence of the extracts compared with the control. QIFGE significantly inhibited the virulence factor production, had inhibitory effect on QS, and resulted in the lower expression of lasR gene. Conclusion: QIFGE showed novel inhibitory effect against QS related virulence factor production, which was unrelated to antimicrobial effect. The extract can down regulate the production of virulence factor and should be evaluated as a candidate for alternative treatment of pseudomonad infections in future.
Why customers participate in social commerce activities? - A laddering analysis

A new phenomenon emerging within virtual communities is a blurring between the social and commercial activities and motivations of participants. This paper explores motivations for participating in social commerce at a micro-business level between members of a virtual community of Malay lifestyle bloggers. The selected community was observed in order to understand the community and 21 participants were interviewed. We used laddering techniques to explore community attributes, the perceived consequences, and their links to the values of participants. We found that virtual community relationship was the main influential factor, and virtual community relationship contributed to the sense of social support as well as customers' trust in social commerce.
Heritage language literacy maintenance: a study of Korean-American heritage learners

How heritage learners successfully maintain their heritage language (HL) and literacy is a significant topic of discussion in the field of bilingual education. This study examines what factors are most closely associated with literacy competence by inspecting Korean heritage learners’ language and literacy practice patterns and their literacy performance. Using language background surveys and Korean writing samples gathered from 56 Korean-English bilingual students in grades 4–12 and university undergraduates, it was discovered that participants’ levels of Korean literacy were positively associated with home Korean language use and focused Korean language practice, whereas they were negatively correlated with years of US stay, years of schooling in the USA, and home English language use. A regression analysis revealed that the quality and range of HL practice was the only significant predictor of HL literacy skills. In addition, a one-way ANOVA indicated no significant difference for HL writing scores across four age groups (i.e. elementary school, middle school, high school, and college), which implies that HL literacy does not necessarily develop or accumulate with cognitive maturity or length of schooling, a finding dissimilar to conventional native language and literacy development.
Induction of labour with vaginal prostaglandin tablet vs gel

The objective of this study was to compare outcomes in women whose labour was induced with vaginal prostaglandin E2 tablets with those induced with prostaglandin gel. We compared outcomes of induction during two audits conducted in 2005 (PGE2 gel) and 2009 (PGE2 tablets). We found that there was no difference in induction rates; 21% in 2005 and 24% in 2009. The recommended dose of prostaglandin E2 was exceeded in 6% and 17% of women induced with gel and tablets, respectively (p = 0.007). There was a difference in use of syntocinon to augment uterine contractions, 39% vs 58% for women induced with gel and tablets, respectively (p = 0.001). There was no difference in overall operative delivery, 37% in gel and 38% in tablets. There was no difference in the proportion of women who had vaginal birth within 24 h; 50% vs 42% for gel and tablet, respectively (p = 0.187). We conclude that compared to prostaglandin gel, women who received prostaglandin tablets were more likely to require syntocinon to augment contractions.
Long‐Term Maintenance of a Transgenic Catharanthus roseus Hairy Root Line

Stably transformed transgenic hairy root cultures have the potential to be a valuable production platform for a variety of secondary metabolites. This study reports that a transgenic hairy root culture of Catharanthus roseus has been stably maintained for over 4.5 years. This culture carries a transgene that expresses the green fluorescent protein under the control of the glucocorticoid‐inducible promoter. Genomic PCR confirmed the presence of the GFP insert within the hairy roots, and induction with dexamethasone caused a significant (p < 0.02) increase in GFP levels.
A Meta-analysis of Innovation and Organizational Size

Findings regarding the direction and intensity of the relation between size and innovation in the literature are contradictory. In the journal Organization Studies in 1992, Damanpour proposed a meta-analytical study in an attempt to clarify the diversity of existing conclusions. The present article is a replica and an extension of that study using the same methodology. Our aim is to (1) bring the pool of accumulated knowledge up to date, examining the time span 1970–2001, and (2) review in greater depth the effects of alternative ways of measuring organizational size. The sample used was made up of 87 correlations drawn from 53 empirical studies published in the most important journals on business administration. The analysis enabled us to confirm the existence of a significant and positive correlation between size and innovation. It also provided evidence showing that the contradictory results obtained in previous studies are due to divergences in the methods used to operationalize one, or more, of the variables to be analysed. The main contribution made by our work stems from the fact that the empirical analysis performs a more thorough breakdown of the definitions of the size variable used in the literature. This may well be a first step toward justifying the differences in the results of the primary studies that analyse the relation under examination.
Dilemmas of Participatory Enquiry: a case study of method‐in‐action

ABSTRACT The purpose of this paper is to problematize the notion of participatory enquiry as a legitimate form of educational evaluation. Using a case study of a new teacher education program the authors describe how they negotiated and enacted an alternative evaluation methodology within a traditional context. The evaluation process was intended to actively engage faculty members and students, as well as representatives of the educational system and the broader community, in self‐reflection and self‐evaluation of their own program. The authors then attempt to turn the methodology back on itself by critically analyzing their own participatory process in terms of a number of dilemmas that arose during the three‐year course of the evaluation. These dilemmas were addressed directly as political issues of method as a means of eliciting discussion and debate about the appropriateness of various forms of enquiry in the assessment and evaluation of higher education.
The narrative construction of intimacy and affect in relationship stories

This study examined how the narrative construction of intimacy and affect in relationship stories predicted individuals’ relationship quality, stability, and mental health. A purposive national sample of 150 individuals in long-term relationships wrote stories about four key relationship events and completed measures of relationship quality and mental health. Stories were analyzed for narrative and linguistic indicators of intimacy-related and affective content. Intimacy-related content was positively associated with relationship quality and mental health. Linguistically-coded affect was not associated with any outcomes. The most robust predictor of relationship quality and mental health was the narratively constructed affective tone of relationship story endings. The narrative construction of positive story endings significantly increased the likelihood of participants remaining together with their partners over time.
Detection of Mixed Infections with Plasmodium spp. by PCR, India, 2014

In 8 malaria-endemic states in India, mixed Plasmodium spp. infections were detected by PCR in 17.4% (265/1,521) of blood samples that microscopy had shown to contain only P. falciparum. The quality of microscopy must be improved because use of PCR for detection of malaria parasites is limited in rural areas.

Sequential Decoding of Trellis Codes through ISI Channels

The Fano algorithm performance is well understood for the standard additive white Gaussian noise (AWGN) channel, and has been shown to be a feasible decoding method for complex codes [12, 13]. This work aims to determine whether the Fano algorithm performance degrades relative to the Viterbi algorithm when the channel has intersymbol interference. We compare Fano and Viterbi decoding by implementing a short constraint-length code. The performance of the code over an ISI channel using Tomlinson-Harashima precoding is compared to the baseline case of a non-ISI channel with the same effective SNR. A long constraint-length code is also evaluated over both the ISI and non-ISI channels, using only Fano decoding (as Viterbi decoding is computationally infeasible). No significant difference was found between performance over the ISI and non-ISI channel. Thus, if sequential decoding can be used beneficially with high constraint length codes over AWGN channels, then it should be equally beneficial over ISI channels. Thesis Supervisor: Mitchell D.
