A Dense Wireless LAN Case Study

While usage and trends for campus wireless LANs have been extensively studied through various deployment instances, very few studies have been done to study short term deployments of wireless LANs, such as those provisioned at the conference venues. We conduct a detailed study of a dense wireless LAN consisting of 82 access points (APs) deployed to serve over 5000 SuperComputing 2004 users. By studying traffic generated by all layers of the TCP/IP protocol stack, we make several observations that differ from those made by the previous wireless LAN studies. In particular, we find that: applications lacking congestion control were more popular than previously reported, channel error rates were higher, a very high percentage of broadcast traffic was present, and that the client mobility was higher than what was previously observed. The two novel features of our custom traffic analyzer that made these observations possible are: 1) it looks at traffic both from the perspective of the total number of bytes, as well as the total number of packets and 2) it conducts a bi-directional traffic analysis from wireless clients to APs and from APs to clients.
Socialisation et génération des connaissances : distinguer les collectifs des communautés

Nous proposons de montrer que tous les groupes qui se forment dans des buts cooperatifs et selon des modalites autonomes vis-a-vis des modeles economiques standards ne sont pas toujours des communautes. A l'heure actuelle, tout semble se passer comme si seulement deux modeles d'organisation de generation des connaissances pouvaient exister (firme et communaute). Pourtant, nous avons assiste depuis quelques annees a l'emergence de collectifs au role economique et social determinant. Un modele presente de maniere inedite les processus de socialisation et les processus de generation des connaissances. Nous demontrons deux points precis. Tout d'abord que communautes et collectifs partagent bien certains modeles de generation des connaissances. Ces deux formes de socialisation ne doivent pas etre opposees de maniere trop brutale. En complement, nous constatons que les processus de formation, les motivations a agir et les rapports a l'innovation se differencient en particulier en ce qui concerne leur temporalite de construction. Finalement, nous montrons que la logique affinitaire qui prevaut dans les collectifs est moins affectuelle que fondee sur des elements de legitimite dans l'espace social investi. La constitution d'un collectif n'est pas une mise en commun, mais une sociation visant a la construction et la promotion de nouvelles valeurs. 2 Socialisation et generation des connaissances : distinguer les collectifs des communautes
Building a Tower of Babel? Integrating Core Motivations and Features of Social Structure into the Political Psychology of Political Action

The political psychology of political action provides the potential for building bridges between scholars from different fields. The main aim of this article is to set some baby steps toward building two conceptual bridges by bringing together a core motivation approach to political action with core features of the social structure that embeds those core motivations. The first conceptual bridge relies on considering a broader motivational model than provided by rational actor or social identity approaches, whereas the second bridge relies on considering core features of the social structure as potentiating these core motivations for political action. More specifically, I first discuss definitions of political action. Second, I identify four converging themes across different literatures on collective action, social movement participation, and voting turnout, resulting in a taxonomy of core motivations for political action (i.e., personal or group-based identity, efficacy, emotion, and moral motivations). Third, in a more explorative fashion I identify four core features of the social structure (ingroup, outgroup, interpersonal network, and institutional features), which I tentatively connect with the taxonomy of core motivations. Finally, I discuss the theoretical, empirical, and practical implications of this generalist, generative, and integrative perspective on political action.
Effect of sex and assay method on serum concentrations of growth hormone in patients with acromegaly and in healthy controls.

BACKGROUND Diagnosis and follow-up of acromegaly is based on measurements of serum growth hormone (GH) concentrations during an oral glucose tolerance test (OGTT). A nadir value <1 microg/L is commonly used to define a normal response, but some authors suggest lower cutoff values. METHODS To compare the results and subsequent patient classification obtained with 3 GH assays, we obtained basal serum samples from 78 apparently healthy adult controls (43 women and 35 men; median age, 32.5 years) and from 71 treated (44 women and 27 men; median age, 55.2 years) and 7 untreated acromegaly patients (4 women and 3 men; median age, 54.6 years), and OGTT was performed on all patients and on 72 of the 78 controls. GH was determined by 2 immunometric assays-a double monoclonal (AutoDELFIA; Wallac) and a monopolyclonal (Immulite 2000; DPC) assay-and in a limited set of samples by an RIA (Spectria RIA; Orion). RESULTS There was a strong correlation (r = 0.995; P < 0.001) between the 2 immunometric methods, but the results obtained with the Immulite 2000 were, on average, 1.4-fold higher than those obtained with the AutoDELFIA. At concentrations around the cutoff (1 microg/L), however, the difference was approximately 2-fold. Overall, the Orion RIA method also showed a good correlation (r = 0.951-0.959) with the other methods, but it did not measure concentrations <2 microg/L. Women had higher basal and OGTT nadir GH concentrations than men. CONCLUSION Reference intervals should be determined separately for each method, and the need for establishing sex-specific reference values should be investigated.
Lecture notes on the Stefan problem

Introduction These notes cover a portion of a course of the Doctorate Modelli e metodi mate-matici per la tecnologia e la società, given in 2001 in Rome. The title of the course was 'Evolution equations and free boundary problems' and its topics included, essentially, an introduction to Stefan and Hele-Shaw problems. Here only the material concerning the Stefan problem is partially reproduced. The present notes assume the reader has some knowledge of the elementary theory of L p and Sobolev spaces, as well as of the basic results of existence and regularity of solutions to smooth parabolic equations. The bibliography is minimal; only books and articles quoted in the text are referenced. See [12], [18] and [20] for further references. I thank the audience of the course for many stimulating comments and questions, and prof. R. Ricci for interesting discussions on the subject of these notes. iii Notation The notation employed here is essentially standard. Appendix D contains a list of the main symbols used in the text.
The Effects of Therapeutic Listening on Bilateral Coordination

up to 250 words): Therapeutic Listening® is a sound-based treatment developed by Sheila Frick, OTR, rooted in sensory integration (Frick & Young, 2009). In Therapeutic Listening® programs, clients listen to music that has been electronically altered (Hall & Case-Smith, 2007). Therapeutic Listening® is an intervention increasingly used by occupational therapists despite the lack of supporting evidence in current literature. A previous thesis study attempted to determine the effectiveness of Therapeutic Listening® through the outcome measure of bilateral movement. In the previous thesis study, three assessments were used to measure bilateral coordination in typically developing children. However, the quantifiable results did not reflect the qualitative observations of the quality of movement (Ben-Haim, Debonis,Schwartz, & Smith-Schwartz, 2015). Because the quantifiable results did not reflect the qualitative results, the effectiveness of the Therapeutic Listening® on quality of movement is not appropriately represented in current research (Ben-Haim et al., 2015). Bilateral coordination development begins in the early stages of a child’s life and provides further foundation for more complex motor skills needed to enhance participation and a child’s quality of life. The purpose of our research study is to examine the effects of Therapeutic Listening® Quickshift in improving bilateral coordination as measured by the quality of movement. To examine the effects, a measure with sufficient sensitivity will be created to detect changes in motor behavior in response to Therapeutic Listening® Quickshift. List of keywords (10 maximum): Therapeutic Listening Quickshift Bilateral coordination Quality of movement Typically developing children Occupational Therapy Description: Therapeutic Listening® is a sound based intervention increasingly used by occupational therapists. The study examines its effects for children in improving bilateral coordination as measured by the quality of movement during several standardized motor assessments. We will utilize a powerpoint presentation to present our study as well as supplemental materials such as videos and handouts. Our presentation will cover the foundations of Therapeutic Listening® and its influence on movement, specifically bilateral coordination. We will present the problem the previous capstone group encountered and how we worked to find a solution to show the qualitative changes in movement. By the time of the conference we hope to have some preliminary data to present about our study.
Investigational drug therapies for the treatment of gastroparesis

ABSTRACT Introduction: Gastroparesis is defined by nausea, vomiting, pain, early satiety and bloating, and characterized by delayed gastric emptying without obvious structural abnormalities. Metoclopramide is widely used, increasing gastric emptying and inhibiting nausea and vomiting. Other drugs are available in certain countries and some are used ‘off-label’ because they increase gastric emptying or inhibit emesis. However, correlation between gastroparesis symptoms and rates of gastric emptying is poor. For anti-emetic drugs, dose-ranging and Phase III trials in gastroparesis are lacking. Areas covered: Gastric motility may still be disordered, leading to nausea, even though gastric emptying is unchanged. One hypothesis is that interstitial cells of Cajal (ICC) are damaged by diabetes leading to gastric dysrhythmia and nausea. Novel approaches to treatment of nausea also include the use of ghrelin receptor agonists, highlighting a link between appetite and nausea. Expert opinion: There is an urgent need to diversify away from historical drug targets. In particular, there is a need to control nausea by regulating ICC functions and/or by facilitating appetite via ghrelin receptor agonists. It is also important to note that different upper gastrointestinal disorders (gastroparesis, chronic unexplained nausea and vomiting, functional dyspepsia) are difficult to distinguish apart, suggesting wider therapeutic opportunity.
Co-culture with Schwann cells is an effective way for adipose-derived stem cells neural transdifferentiation

Introduction Adipose-derived stem cells (ADSCs) could accomplish neural transdifferentiation with the presence of certain growth factors in vitro. It has been proved that bone marrow stromal cells (BMSCs) can realize neural transdifferentiation only by being co-cultured with Schwann cells (SCs), and in our former studies we have confirmed that ADSCs could do so too. This paper aims to investigate whether the neural induction efficiency of co-culture is as high as that of other strategies using chemicals or chemicals combined with some growth factors. Material and methods We isolated and multiplied ADSCs from adult Sprague-Dawley rats, and SCs from sciatic nerves of 1-to-2-day-old Sprague-Dawley rat pups, then induced ADSCs neural transdifferentiation through 2% dimethyl sulphoxide (DMSO) and DMSO combined with growth factors. Meanwhile we co-cultured ADSCs and SCs in Transwell culture dishes without intercellular contacts. Immunostaining and RT-PCR were adopted to investigate the neural transdifferentiation of ADSCs. Then we compared the expression differences for genes S100, nestin and GFAP of the above three protocols by real-time PCR. Results Both immunostaining and RT-PCR proved that ADSCs could accomplish neural transdifferentiation through each of the above three protocols. And real-time PCR further shows that the gene expression relative quantities for the above three genes are not statistically different between co-culture and induction through DMSO combined with growth factors (p > 0.05), but both of them are statistically different from induction only by DMSO (p < 0.05). Conclusions Co-culturing ADSCs and SCs may be a simple, effective and practical way for ADSCs neural transdifferentiation.
Epidemiology of allergic rhinitis in Quebec: from a 2008 population-based survey.

INTRODUCTION Our objective was to estimate the prevalence of symptoms and the proportion of a lifetime physician-based diagnosis of allergic rhinitis (AR) in the province of Quebec among people aged 15 years and older. METHODS The 2008 Quebec Population Health Survey provided data on the prevalence of symptoms and proportion of lifetime physician-based diagnoses of AR. The prevalence of symptoms was defined as the proportion of individuals who, in the absence of a cold or the flu, had nasal and ocular symptoms in the 12 months before the survey. RESULTS The reported prevalence of AR symptoms was 17%, although 9% did not have a diagnosed condition. Reported prevalence was lowest in those aged 65 years and older (12%) and was more common among women (19%) than men (15%). The estimated prevalence of lifetime physician-based diagnosis was 17%. CONCLUSION AR prevalence is high in Quebec with about 1 in 6 people experiencing symptoms. The condition is underdiagnosed and might also be undertreated.
Weight loss interventions in chronic kidney disease: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES Obesity is an independent risk factor for development and progression of chronic kidney disease (CKD). We conducted a systematic review to assess the benefits of intentional weight loss in patients with non-dialysis-dependent CKD and glomerular hyperfiltration. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We searched MEDLINE, SCOPUS, and conference proceedings for randomized, controlled trials and observational studies that examined various surgical and nonsurgical interventions (diet, exercise, and/or antiobesity agents) in adult patients with CKD. Results were summarized using random-effects model. RESULTS Thirteen studies were included. In patients with CKD, body mass index (BMI) decreased significantly (weighted mean difference [WMD] -3.67 kg/m(2); 95% confidence interval [CI] -6.56 to -0.78) at the end of the study period with nonsurgical interventions. This was associated with a significant decrease in proteinuria (WMD -1.31 g/24 h; 95% CI -2.11 to -0.51) and systolic BP with no further decrease in GFR during a mean follow-up of 7.4 mo. In morbidly obese individuals (BMI >40 kg/m(2)) with glomerular hyperfiltration (GFR >125 ml/min), surgical interventions decreased BMI, which resulted in a decrease in GFR (WMD -25.56 ml/min; 95% CI -36.23 to -14.89), albuminuria, and systolic BP. CONCLUSIONS In smaller, short-duration studies in patients with CKD, nonsurgical weight loss interventions reduce proteinuria and BP and seem to prevent further decline in renal function. In morbidly obese individuals with glomerular hyperfiltration, surgical interventions normalize GFR and reduce BP and microalbuminuria. Larger, long-term studies to analyze renal outcomes such as development of ESRD are needed.
Correction of the operating modes of an induction motor with asymmetrical stator windings at vector control

Operation of an induction motor with electric or magnetic asymmetry of stator windings results in uneven distribution of losses in copper across stator phases and appearance of variable components of electromagnetic torque and consumed power. Such operating modes considerably influence both operation of the motor and operation of the technological mechanism on the whole, as there appears continuous oscillation of motor torque and speed. A possibility of compensation for stator windings asymmetry influence on dynamic and power characteristics of an electric drive with a vector control is demonstrated in the paper. Two structures of induction motor control systems are presented: a system of compensation for electromagnetic torque variable component and a system of compensation for consumed active power variable component. It is shown that the former system provides decrease of electromagnetic torque variable component causing additional vibrations of the motor. The latter system provides decrease of the variable component of consumed active power and thermal overload of motor separate phases.
Host risk factors for the development of multiple non‐melanoma skin cancers

Non‐melanoma skin cancer (NMSC) is the most common cancer in the US, and having multiple lesions conveys substantial cost and morbidity for the individual involved. Although there are data available on risk factors for NMSC, there are currently few studies that identify specific risk factors for development of multiple NMSCs. We evaluated host risk factors for multiple NMSCs among men (Health Professionals Follow‐up Study) and women (Nurses’ Health Study). Compared with individuals with a single NMSC, having greater number of sunburns was a risk factor for developing ≥2 NMSCs [≥10 sunburns, cumulative relative risk (RR) = 1.21, 95% confidence interval (CI): 1.07–1.36] and a higher risk of developing ≥11 NMSCs (≥10 sunburns, RR = 2.33, 95% CI: 1.57–3.46). Inability‐to‐tan was associated with risk of developing ≥2 NMSCs (cumulative RR = 1.29, 95% CI: 1.18–1.40) and a higher risk of developing ≥11 NMSCs (RR = 1.91, 95% CI: 1.50–2.43). Men had an increased risk of developing ≥2 NMSCs (cumulative RR = 1.53, 95% CI: 1.40–1.66). Risk of developing 2–4, 5–10 and ≥11 NMSCs increased with age. Other risk factors for developing ≥2 NMSCs included red natural hair colour (cumulative RR = 1.23, 95% CI: 1.07–1.42), family history of melanoma (cumulative RR = 1.15, 95% CI: 1.03–1.28), and having ≥6 nevi on the left arm (cumulative RR = 1.22, 95% CI: 1.07–1.40). In conclusion, physicians caring for individuals with incident NMSCs may consider paying special attention to those at highest risk for developing additional tumours, especially males and those with a history of ≥10 lifetime sunburns, by performing routine full skin examinations and counselling for aggressive photoprotection.
Bouquets, Brickbats and Blinkers: Total Quality Management and Employee Involvement in Practice

To its advocates, TQM is unequivocally good and leads to the empowerment of employees and deservedly attracts bouquets. Alternatively, those from a labour-process perspective hurl brickbats, arguing that it represents an intensification of work, shifting the frontier of control firmly in management's favour. We argue, however, that both of these perspectives are blinkered and that the reality is more dependent on local circumstances and motives.
Gossipmule: Improving association decisions via opportunistic recommendations

The IEEE 802.11 association procedure lacks Quality of Experience (QoE) mechanisms. High delays and an association decision based on the Received Signal Strength Indicator (RSSI) do not lead to a QoE-based association among stations (STAs) and access points (APs). This paper presents Gossipmule, a novel approach that takes advantage of opportunistic communication among STAs to improve the association procedure in 802.11 wireless networks. STAs in Gossipmule exchange information prior to association by gossiping on the capabilities and performance of the APs. The knowledge gathered by this participatory sensing is used to rank the APs and update the recommendation that will be given to other peers. Results from simulations show a measurable improvement regarding the current delay and the achieved throughput.
Is food addiction a valid phenomenon through the lens of the DSM-5?

Australian & New Zealand Journal of Psychiatry, 48(3) Recent literature has seen a rise in interest in the phenomenon of food addiction. Nolan (2013) highlighted that Medline has had a sevenfold increase in the number of papers indexed by the term food addiction since 2008. However, a lack of consensus regarding the entity of food addiction and whether it constitutes a ‘true’ and valid addiction pervades. Clearly the ideology of food addiction and its accompanying nosological status (if such a status should exist) has vast implications. Especially in the context of the current global epidemic of overweight and obesity with its associated health, psychological, economic and social consequences, as logically food addiction would be a significant aetiological factor fuelling this epidemic (Lindberg, et al., 2011). This viewpoint seeks to briefly highlight the debate regarding whether food addiction is a ‘true’ and valid addiction, through the lens of the recently released DSM-5 (American Psychiatric Association, 2013). Firstly, the status of food addiction as a ‘true’ addiction in relation to the DSM-5 generally will be discussed, before moving on to a discussion of food addiction in relation to the nosology of substance use.
Robust watermarking for medical images based on Arnold scrambling and DWT-DFT

Currently, digital information management system has played an increasingly important role in modern health care system. However, the Information security issues are exposed gradually. When an exception occurs, digital medical image, as a diagnostic basis, can not serve as the evidence of medical accident case, and may result in delayed diagnosing or even misdiagnosing for patients. In order to solve this problem, this paper proposes an algorithm that employs the Arnold scrambling to preprocess on original watermarking, such that the watermarked medical image technology has security under the cryptography sense, for double protection. Moreover, the algorithm combines the image visual feature vector, encryption technology and the concept of third party, without the sophisticated process to finding the Region of Interest (ROI) of medical images. Therefore, watermarking can be extracted and embedded more faster. The experimental results show that the algorithm has satisfactory robustness and invisibility under conventional attacks and geometrical attacks in different levels.
Analytical Sociology: Actions and Networks (Wiley Series in Computational and Quantitative Social Science) by Gianluca Manzo (ed.)

I was keen to review this book and find out how Analytical Sociology (AS) has developed after being impressed and refreshed by Hedström and Swedberg’s Social Mechanisms in 1995. Having read it, my impression is that some excellent research is being done (and branded as AS) but that this may not really reflect the existence of a distinctive and coherent field. The similarities and contrasts between the development of ABM and AS in this context may also be of interest to readers of JASSS.
