Clusters and constellations: Untwisting shortened links
Authors: Tonkin Emma , Pfeiffer Heather D. 
Published: January 2013

AbstractFrequent users of social services such as Twitter are now familiar with the use of URL shortening services to produce compressed versions of actionable URLs. Although the typical user motivation for these is often taken to be convenience – particularly in the matter of reducing the amount of space taken by a link during a tweet, these shortening services are also used for various other purposes, including the collection of analytics for marketing purposes. In this poster we present the initial findings from our analysis of 350,000 tweets from Twitter on a subject close to the hearts of many ASIS&T conference attendees – the TSA (transport security administration). These tweets, gathered over a period of six weeks, primarily collect together reactions to a number of events and announcements of both positively and negatively nature, and as such, contain a large number of encoded URLs. We show the result of back‐tracking URLs to their origin, demonstrating that it is now commonplace for URLs to be redirected through more than one redirection service. From analysis of the shortening services used we demonstrate that the majority of shortened URLs make use of one of a very small number of services, although these may be identified via an alias. Finally, we discuss the implications of these findings, both in terms of preservation and our ability to access the context of older Twitter conversations, and in terms of the implications for developers of user applications or content analysis platforms.
Factors Influencing the Patient with Rheumatoid Arthritis in their Decision to Seek Podiatry

Published: January 2013

AbstractIntroductionDespite the level of foot involvement in rheumatoid arthritis (RA), and the literature to support early assessment of foot care needs, local referral of patients to podiatry has been occurring too late to instigate certain preventative interventions. Preliminary fieldwork has highlighted that the primary responsibility for the instigation of this lies with the patient. The present study describes the factors that influence the patient with RA in their decision to self‐report foot problems.MethodA case study research strategy was employed. Nine patients attending the outpatient rheumatology department participated in the study and data were gathered through semi‐structured interviews. This information was analysed using a framework approach.ResultsThe key themes derived from the data suggested that there are a variety of factors influencing the patient's decision to self‐report foot concerns. Some will act to encourage the action and others will act to oppose it. Other factors can influence the decision either way, depending on the individual patient (psychological state, previous experience, body image changes). In addition, age, gender, and cultural and social aspects are also significant.ConclusionDue to the multitude of factors influencing the individual's decision to seek help, the patient cannot be given sole responsibility for their foot health if we wish to achieve timely and appropriate podiatry, as recommended in the literature. Responsibility should be three‐way; the patient, the members of the rheumatology team and, once in the podiatry service, the podiatrist should maintain this. Copyright © 2013 John Wiley & Sons, Ltd.
Prenatal diagnosis of MPPH syndrome
Authors: De Keersmaecker Bart , Van Esch Hilde , Van Schoubroeck Dominique , Claus Filip , Moerman Philippe , De Catte Luc 
Published: January 2013

ABSTRACTWe report the prenatal sonographic detection of a fetus with megalencephaly, polymicrogyria, postaxial polydactyly and hydrocephaly. Only 14 patients have been reported in the literature so far, all but one were diagnosed postnatally. The polymicrogyria in the frontoparietal lobe was confirmed by prenatal magnetic resonance imaging. Additionally, a hypoplastic thymus as seen in a 22q11 deletion was present. Although polymicrogyria along with pre‐axial polydactyly has been described in 22q11 deletion, the diagnosis of Di George syndrome was ruled out. The etiology of megalencephaly, polymicrogyria, postaxial polydactyly and hydrocephaly has not been revealed yet. A dominant as well as recessive inheritance has been suggested. © 2013 John Wiley & Sons, Ltd.

AbstractExtended X‐ray absorption fine structure above the Ga–K edge has been used to study the local structure of heterointerfaces in GaN/AlN multiple quantum wells (MQWs) grown by ammonia molecular beam epitaxy. The thickness of AlN and GaN layers in MQWs were evaluated using transmission electron microscopy, X‐ray diffraction and Raman spectroscopy. Two sets of MQWs structures with the number of period about of 20 and more than 100 were studied. The Ga‐Ga interatomic distance in MQWs is lower than that in bulk GaN due to elastic compression of GaN layers in MQWs. This effect is less pronounced in thick structures because of almost full relaxation of GaN layers. The Ga‐Al interatomic distance in thick MQWs is too long, about 0.1 Å, longer than typical values for AlGaN alloys. Then number of Ga cations in the second coordination shell of Ga atoms is lower than that predicted for abrupt heterointerfaces that evidences intermixing of heterointerfaces. The intermixing degree depends on the total thickness of MQWs (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: January 2013

Objective Outbreaks of dermatitis linearis have been documented worldwide. We present a case series of dermatitis linearis from Latin America to highlight the importance of this clinical entity. Clinical, historical, epidemiological, and pathological aspects of the condition are discussed, and a concise current approach to the management and treatment of this morbidity is presented. Methods We present a series of 4 selected cases reflecting the clinical spectrum exhibited in dermatitis linearis by Paederus along with a review of the literature. Results In this review we demonstrate the need for awareness of dermatitis linearis as a clinical entity that must be considered in the broad list of differential diagnosis embracing vesicating linear lesions. Conclusions Capture of the insect, epidemiologic features, and a high clinical suspicion can aid in making the correct diagnosis. Primary prevention through public awareness, decreased use of artificial lighting, and mosquito nets can limit the extent and severity of outbreaks.

SUMMARYBlockage of pathogen transmission through water decontamination is considered an important strategy for the prevention of schistosome infection. Many believe that this strategy is feasible, but it has yet to be achieved. Silver has a long history of use as a disinfectant. With the emergence of nanotechnology, silver can be shaped into nanoparticles which have been found to possess superb antimicrobial activities. In this light, we investigated the effects of silver nanoparticles (AgNPs) on Schistosoma japonicum cercariae. AgNPs rapidly induced cercarial tail-shedding, agitated behaviour and a decrease in cercarial secretion in a dose-dependent manner. Prolonged treatment was found to be cercariocidal, which nevertheless might be attributable to AgNP-induced cercarial tail loss rather than to toxicity. Higher concentrations of AgNPs (125 μg mL−1 and above) completely blocked cercarial infectivity. Despite decreased infectivity, cercariae exposed to lower concentrations of AgNPs for 30 min were still found capable of infecting hosts even without their tails, suggesting that tail loss does not necessarily signify a total loss of infective ability. We also found that silver ions (Ag+) were heavily involved in the observed cercarial responses of AgNPs. Our observations provide insight into the interactions between the larvae of helminth parasites and nanoparticles.
Efficiency improvements of public hospitals under a capitation payment scheme
Authors: García-Lacalle Javier , Martín Emilio 
Published: January 2013

AbstractIn a context of cost containment and demands for better quality in public health care, payment systems are used as an instrument to promote efficiency improvements in service providers. Andalusia has adopted an original type of risk-adjusted capitation payment mechanism to reimburse public hospitals. This paper presents the main characteristics of the reimbursement mechanism of the Andalusian Health Service highlighting some differences with the mechanisms adopted in other parts of Europe. The paper also explores the evolution of the efficiency and quality of the hospitals after its implementation using the Malmquist index. Results indicate that hospitals have slightly improved their efficiency, particularly urban hospitals, and these improvements are not significantly related to a negative evolution of quality. However, it is not possible to assert to what extent, improvements are the consequence of the new payment system. The organisation of theServicio Andaluz de Saludand the limited competition between hospitals reduce the effectiveness of the reform.
First Report of Bacterial Leaf Spot on Cichorium intybus Caused by Pseudomonas cichorii in Florida
Authors: Zhang S. , Fu Y. 
Published: January 2013

Italian dandelion (Cichorium intybus L.) is a leafy chicory plant grown as a fresh vegetable in salads. In August 2011, necrotic lesions were observed on leaves of about 20% of the Italian dandelion plants in an experimental field at the Tropical Research and Education Center (TREC) of the University of Florida in Homestead, FL. The lesions were dark brown with a yellow halo and most were irregular in shape. Some lesions formed along the leaf edge and developed into large lesions up to 20 to 30 mm long. Symptomatic leaf tissues were cut into small pieces (2 to 3 mm), sterilized in 10% Clorox (0.6% sodium hypochlorite) for 2 min following surface disinfection in 70% ethanol for 30 s, placed on nutrient agar (NA), and incubated at 28°C in the dark for 4 to 5 days. A bacterium was consistently isolated from the leaf lesions. Colonies of these bacteria were raised, opaque, and round with a slightly irregular, colorless margin while the center was light brown. The colonies were gram-negative with yellow fluorescence appearance on Pseudomonas F agar (Becton, Dickinson and Company, Sparks, MD). LOPAT tests were carried out to further identify the species of this fluorescent pseudomonad (2). The bacterium was levan negative, oxidase positive, potato rot negative, arginine dihydrolase negative, and tobacco hypersensitivity positive. Results from this test indicated that the bacterium belongs to LOPAT group III of fluorescent pseudomonads. Bacterial identity was further confirmed as Pseudomonas cichorii by amplifying the 16S rRNA gene with the universal bacterial primers 8F and 1492R (1) and sequence analysis (GenBank Accession No. KC311733). The partial 1,361-bp 16S rRNA gene sequences had 100% identity with P. cichorii (JF951725.1), which was isolated from infected soybean plants. Pathogenicity of the isolate was tested twice by spraying a suspension of the bacterium (107 CFU/ml) onto three 4-week-old plants until runoff. The control plants were sprayed with sterile distilled water. All plants were covered with plastic bags to maintain moisture for 48 h in an air-conditioned greenhouse (22 ± 1°C). Similar lesions were observed on the inoculated plant leaves 5 to 7 days after inoculation, whereas no lesions were developed on the control plants. Bacterial colonies with same morphology were recovered from the lesions, fulfilling Koch's postulates. P. cichorii is widespread worldwide with an important economic impact on celery, chrysanthemum, and lettuce. In South Florida, P. cichorii was reported as the causal agent of bacterial leaf spot on escarole (Cichorium endivia L.) (3). To our knowledge, this is the first report of bacterial leaf spot on Italian dandelion caused by P. cichorii in Florida. References: (1) J. P. Galkiewicz and C. A. Kellogg. Appl. Environ.

The Great Recession, jobs and social crises: policies matter
Authors: Chowdhury Anis , Islam Iyanatul , Lee Donald 
Published: January 2013

PurposeThe purpose of the paper is to review the social consequences of the Great Recession of 2008‐2009. In particular, it looks at impacts on the world of work – unemployment, informal and vulnerable employment, working poor and youth unemployment, and on public health – hunger and malnutrition, suicides, domestic violence and child abuse. In all fronts, the Great Recession had serious adverse impacts and morphed into a global social crisis. The situation is made worse due to obsessions with fiscal consolidation in the midst of tepid and uncertain recovery. The paper argues that policies matter and advocates for strengthening social protection and continued stimulus in order to ensure robust recovery.Design/methodology/approachThe paper is a general review and it draws on the findings of the United Nations flagship publication, Report of the World Social Situation 2011. It is an analytical narrative of impacts of on‐going economic crisis.FindingsThe paper finds a worsening employment situation – rise in unemployment, informal and vulnerable employment, youth unemployment, and working poverty. It also finds adverse public health impacts in terms of rise in malnutrition and hunger, suicide rates, domestic violence and child abuse. Finally the paper finds that policies matters in mitigating worst impacts as well as sustaining recovery.Research limitations/implicationsThe findings are tentative as the social impacts of economic crisis become obvious after a long time lag.Originality/valueThe paper argues that policies matter and advocates for strengthening social protection and continued stimulus in order to ensure robust recovery.
A transcendent code of ethics for marketing professionals
Authors: Payne Dinah , Pressley Milton 
Published: January 2013

PurposeThe purpose of this paper is to develop a single code of ethics that could be used regardless of the venue or specialty of the marketing professional. The paper first provides a literature review of research in the areas of ethics pertaining to marketing professionals. Then a review of a wide variety of codes of business ethics, marketing ethics, model codes, and professional ethics produces the idea that, while there are some differences in how the codal principles are presented, there are sufficient similarities in the codes' principles of professional conduct to merit the consideration of a single code of marketing ethics – one that can be used regardless of the venue or specialty of the marketing professional.Design/methodology/approachThe paper introduces a broad literature review followed by the development of a transcendent code of ethics for all marketers.FindingsUsing the above as well as: historically and more broadly known theories of ethics, and currently‐used codes of professional marketing ethics, including those from the American Marketing Association (AMA), the American Association of Advertising Agencies (AAAA), and the Sales and Marketing Executives International (SMEI), the authors make an attempt to determine the most prominent, efficacious principles of ethics and to shape a single code of professional conduct for marketing students, educators and practitioners – regardless of their area of specialty.Research limitations/implicationsThe proposed code is subject to debate and will likely not be the model eventually used. The authors hope that the code proposed will stimulate further research, discussion and formulation.Practical implicationsA single code of ethics that could be utilized by anyone confronted with an ethical marketing issue would be useful in easing the difficulties associated with challenging ethical dilemmas in marketing.Social implicationsDrawing on traditional frames of ethics and combining those principles with principles found in the marketing ethics literature, the authors generate a single code of ethics that not only marketers can use, but that others in society can also identify with and feel confidence in – thus alleviating concerns of mistrust or misunderstanding between those marketing products and services and the stakeholders in the society in which those products and services are being marketed.Originality/valueNo transcendent code of marketing ethics currently exists. The three most prominent are unique to their fields – each leaving out portions necessary to be transcendent. Thus, the proposed code is original and has the practical social implication values noted above.
Marketing as a response to paradox and norms in the 1960s and 1970s
Authors: Bourassa Maureen A. , Cunningham Peggy H. , Handelman Jay M. 
Published: January 2013

PurposeThis study seeks to investigate the interaction between marketers' strategic behaviors, social norms, and societal stakeholders within a particular historical time period, the 1960s and 1970s.Design/methodology/approachThe study's findings are based on an analysis of two dominant retail industry trade publications, Chain Store Age and Progressive Grocer.FindingsThe analysis reveals an intriguing array of strategic marketing activity throughout these two decades not captured in considerations of marketing strategy at the time. The retailers examined engaged in two interesting behaviors. First, they responded to a wide range of stakeholder demands in a paradoxical fashion. Second, as retailers were confronted with social norms, instead of conforming to these norms they worked to help influence and shape them to their own advantage. This examination of retailers' behaviors over two decades has allowed the authors to present an intriguing new dimension to the understanding of marketing strategy.Originality/valueThe study found that throughout the 1960s and 1970s, marketers appeared to be actively engaged in a social dialogue. Through this dialogue, they not only responded to norms, but also attempted to shape the norms that came to define legitimate behavior for the marketers. This kind of strategic marketing endeavor was not accounted for in the managerial school of thought that dominated marketing thinking at the time.
Random simulation method for accuracy test of grey prediction model
Authors: ke Zhang 
Published: January 2013

PurposeThe purpose of this paper is to establish a random simulation method to compare the forecasting performance between grey prediction models, and between grey model and other kinds of prediction models. Then, the different performance of three grey models and linear regression prediction model is studied, based on the proposed method.Design/methodology/approachA random simulation method was proposed to test the modelling accuracy of grey prediction model. This method was enlightened by Monte Carlo simulation method. It regarded a class of sequences as population, and selected a large sample from population though random sampling. Then, sample sequences were modeled by grey prediction model. Through modeling error calculation, the average error of grey model for the sample was obtained. Finally, the grey model accuracy for this kind of problem was acquired by statistical inference testing model. Through the statistical significant test method, the modeling accuracy of grey models for the same problem can be compared. Also, accuracy difference between grey prediction model and regression analysis, support vector machine, neural network, and other forecasting methods can be also compared.FindingsThough random simulation experiments, the following conclusion was obtained. First, grey model can be applied to the long sequence whose growth rate was less than 20 per cent, and the short sequence whose growth rate was less than 50 per cent. Second, GM(1,1) cannot be applied to a long sequence with high growth. Third, growth rate was a more important factor than growth length on modeling accuracy of GM(1,1). Fourth, when the sequence length was short, accuracy of GM(1,1) model was higher than linear regression. While the length of the sequence was more than 15, and the growth rate in [0‐10 per cent], two kinds of modeling error was not significantly different.Practical implicationsThe method proposed in the paper can be used to compare the performance of different prediction models, and to select appropriate model for a prediction problem.Originality/valueThe paper succeeded in establishing an accuracy test method for grey models and other prediction models. It will standardize the grey modelling and contribute to application of grey models.
