Energy‐efficient task allocation for service provisioning in machine‐to‐machine systems

Machine‐to‐Machine (M2M) communication systems enable autonomous communication between heterogeneous devices. In many applications, those devices are used to obtain measurements from sensors connected to them. By integrating M2M with the Internet of things paradigm, sensors and the data they obtain can be easily accessed via Internet infrastructure. This novelty, along with the advancement of processing power on small devices and the possibility to connect more sensors to one sensing device, poses new challenges and opens new opportunities in the area. This paper presents an algorithm and a protocol devised for task allocation to nodes of the M2M architecture where M2M devices are battery powered. The presented mechanism tackles some of the identified challenges within the area. First challenge is to determine the right node for performing data analysis. Certain data analysis tasks can be performed on device, instead of only on servers, which is a traditional approach. Another challenge is to relate the process of obtaining measurements with user needs, i.e. to collect data only when users have interest in it. The last identified challenge is to extend lifetime of services with higher priority, instead of prolonging lifetime of all devices within the network. Adoption of the proposed mechanism is justified on specific services in a smart home environment. Copyright © 2017 John Wiley & Sons, Ltd.
The Role of Dice in Election Audits – Extended Abstract

Random audits are a powerful technique for statistically verifying that an election was tabulated correctly. Audits are especially useful for checking the correctness of electronic voting machines when used in conjunction with a voter-verified paper audit trail (VVPAT). While laws in many states already require election audits, they generally do not address the procedure for generating the random sample [12]. The sample generation procedure, however, is critical to the security of the audit, and current practices expose a security flaw. This paper examines the problem of sample selection in the context of election audits, identifies necessary requirements for such a procedure, and proposes practical solutions that satisfy those requirements.
Romantic breakups on Facebook: new scales for studying post-breakup behaviors, digital distress, and surveillance

Research on Facebook has primarily focused on the benefits of social connectivity, paying little attention to the ways in which this social networking site complicates the termination of romantic relationships. The present exploratory study employs a mixed-methods approach to examine the breakup practices of young people on Facebook and to develop new scales for measuring surveillance of an ex and Facebook breakup distress. The aim of the study is to better understand the relationship between internet electronic surveillance and breakup distress. Findings show that content on Facebook can be a significant source of distress for individuals after a breakup. Young people who engage in higher levels of internet electronic surveillance experience more breakup distress. A methodological innovation of our study is the integration of narrative data obtained from in-depth interviews with survey results, highlighting how qualitative analysis can enrich quantitative studies examining social networking. We discuss implications for research into social relations, breakups, and social media.
Identity, Wearing Many Hats, and Boundary Blurring: The Mindful Psychologist on the Way to the Olympic and Paralympic Games

In this article, the authors explore professional identity, multiple roles, and boundary-blurring when working in the sport psychology area with Olympic and Paralympic athletes. Data for this article were collected from case notes, a self-reflective logbook, and supervision sessions during two years before the Games. This study is a tale of a neophyte registered (licensed, chartered) psychologist entering into the high pressure world of international Olympic and Paralympic sports. Key features include how the sport psychologist in the lead-up to the Games can remain grounded in mindful practice and be an island of calm for athletes and coaches in what has to be one of the most stressful sporting events athletes and coaches experience. Dave's (the psychologist's) story illustrates what he and his supervisor believe is the foundation of almost any service—the development and nurturing of caring, holding, loving, attuned, and non-judgmental relationships with athletes and coaches during major international sporting events.
Der schematherapeutische Moduszirkel in der verhaltenstherapeutischen Supervision

ZusammenfassungHintergrund: Ein wesentlicher Gegenstand der Supervision ist die Reflexion der Beziehung zwischen Therapeut und Patient, die ein Konzept zur übersichtlichen Erfassung der jeweiligen Persönlichkeitsstruktur und deren Interaktion erfordert. Die Moduslandkarte ist eine solche Konzeptualisierung, und in einem Moduszirkel-Memo lässt sich eine Interaktionssequenz kompakt analysieren und konstruktiv auflösen. Methode: In diesem Beitrag wird das Konstrukt des Moduszirkels herausgelöst aus seinem schematherapeutischen Hintergrund als allgemeinpsychologisches Konstrukt dargestellt. Dabei wird skizziert, wie es in eine verhaltenstherapeutische Ausbildungssupervision eingebaut werden kann. Mögliche Moduszirkel werden beschrieben und Auswirkungen auf die Supervisionsarbeit sowie Grenzen zur Selbsterfahrung herausgearbeitet. Ergebnisse: Dieses Vorgehen kann den Supervisanden einen minimalen Zugang zur motivationalen Ebene der Patienten gewähren und eine motivorientierte Beziehungsgestaltung ermöglichen, anstatt sich in Moduszirkeln auf der Bewältigungsebene verstricken zu lassen. Schlussfolgerung: Die Verwendung der Moduslandkarte und des Moduszirkel-Memo kann die verhaltenstherapeutische Supervision im Sinne einer minimalen vertikalen Verhaltensanalyse erweitern, das therapeutische Verhältnis zwischen Arzt und Patient verbessern und zur Vermeidung dysfunktionaler therapeutischer Interaktionen beitragen.
Demographic and sexual characteristics of nonresponders to sexual experience items in a national survey

Given the heavy reliance on self‐report measures, volunteer bias due to patterns of nonresponse is an important issue in sex research. In the present study, rates of nonresponse to self‐administered sexual experience questions posed to individuals in a national probability sample (NORC data; Davis & Smith, 1990) of English‐speaking adult households (N = 3,646) were analyzed as a function of demographic characteristics. Differences between responders and nonresponders in reported sexual experience on other items were also investigated. In general, rates of response to most of the sexuality items were quite high. With regard to three of the four sexual experience questions considered, men were more likely than women to respond. Among both men and women, nonresponders to each of the four sexuality items were generally older and reported less income and educational attainment than did responders. There were no differences in likelihood of responding to the sexuality items as a function of religious affiliatio.
Targeting mTORC1–Mediated Metabolic Addiction Overcomes Fludarabine Resistance in Malignant B Cells

MTOR complex-1(mTORC1) activation occurs frequently in cancers, yet clinical efficacy of rapalogs is limited because of the associated activation of upstream survival pathways. An alternative approach is to inhibit downstream of mTORC1; therefore, acquired resistance to fludarabine (Flu), a purine analogue and antimetabolite chemotherapy, active agent for chronic lymphocytic leukemia (CLL) was investigated. Elevated phospho-p70S6K, also known as RPS6KB1 (ribosomal protein S6 kinase, 70kDa, polypeptide 1) (T389), an mTORC1 activation marker, predicted Flu resistance in a panel of B-cell lines, isogenic Flu-resistant (FluR) derivatives, and primary human CLL cells. Consistent with the anabolic role of mTORC1, FluR cells had higher rates of glycolysis and oxidative phosphorylation than Flu-sensitive (FluS) cells. Rapalogs (everolimus and rapamycin) induced moderate cell death in FluR and primary CLL cells, and everolimus significantly inhibited glycolysis and oxidative phosphorylation in FluR cells. Strikingly, the higher oxidative phosphorylation in FluR cells was not coupled to higher ATP synthesis. Instead, it contributed primarily to an essential, dihydroorotate dehydrogenase catalyzed, step in de novo pyrimidine biosynthesis. mTORC1 promotes pyrimidine biosynthesis by p70S6 kinase–mediated phosphorylation of CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase; Ser1859) and favors S-phase cell-cycle progression. We found increased phospho-CAD (S1859) and higher S-phase population in FluR cells. Pharmacological inhibition of de novo pyrimidine biosynthesis using N-phosphonacetyl-l-aspartate and leflunomide, RNAi-mediated knockdown of p70S6K, and inhibition of mitochondrial respiration were selectively cytotoxic to FluR, but not FluS, cells. These results reveal a novel link between mTORC1-mediated metabolic reprogramming and Flu resistance identifying mitochondrial respiration and de novo pyrimidine biosynthesis as potential therapeutic targets. Implications: This study provides the first evidence for mTORC1/p70S6K-dependent regulation of pyrimidine biosynthesis in a relevant disease setting. Mol Cancer Res; 12(9); 1205–15. ©2014 AACR.
Features : February 2001 Feynman ' s challenge

McLellan's motor now sits in a display case at the California Institute of Technology and has long since ceased to spin. Meanwhile, in the field that Feynman hoped to incite, the wheels are turning both figuratively and literally in many university and corporate laboratories, and even on industrial production lines. Indeed, the field of microelectromechanical systems (MEMS), which became firmly established in the mid-1980s, has now matured to the point where we can be rather blasé about the mass production of diminutive motors that are hundreds of times smaller than McLellan's original. Along the way the MEMS community has developed some truly intriguing products from digital projectors that contain millions of electrically driven micromirrors to microscale motion sensors that sit in cars ready to deploy airbags (figure 2).
Characterization of Microbial Community Structure in the Surface Sediment of Osaka Bay, Japan, by Phospholipid Fatty Acid Analysis

Twenty-eight sediment samples collected from Osaka Bay, Japan, were analyzed for phospholipid ester-linked fatty acids (PLFA) to determine regional differences in microbial community structure of the bay. The abundance of three major groups of C10 to C19 PLFA (saturated, branched, and monounsaturated PLFA), which accounted for 84 to 97% of the total PLFA, indicated the predominance of prokaryotes in the sediment. The distribution of six clusters obtained by similarity analysis in the bay revealed a marked regional distribution in the PLFA profiles. Total PLFA concentrations (0.56 to 2.97 μg/g [dry weight] of the sediment) in sediments also showed marked variation among the stations, with higher concentrations of total PLFA in the central part of the bay. The biomass, calculated on the basis of total PLFA concentration, ranged from 0.25 × 108 to 1.35 × 108 cells per g (dry weight) of the sediment. The relative dominance of microbial groups in sediments was described by using the reported bacterial biomarker fatty acids. Very small amounts of the characteristic PLFA of microeukaryotes in sediments indicated the restricted distribution of microeukaryotes. By examining the distribution of clusters and groups of microorganisms in the bay, there were two characteristics of the distribution pattern: (i) the predominance of anaerobic bacteria and gram-positive prokaryotes, characterized by the high proportions of branched PLFA in the eastern and northeastern sides of the bay, where the reported concentrations of pollutants were also high, and (ii) the predominance of aerobic prokaryotes and eukaryotes, except for a few stations, in the western and southwestern sides of the bay, as evidenced by the large amounts of monounsaturated PLFA. Such significant regional differences in microbial community structure of the bay indicate shifts in microbial community structure.
Phenomenological Psychopathology and Schizophrenia: Contemporary Approaches and Misunderstandings

Abstract:The present paper clarifies key issues in phenomenology and phenomenological psychopathology (especially of schizophrenia) through a critique of a recent article that addresses these topics. Topics include (1) Phenomenology's role in clarifying issues not amenable to purely empirical methods; (2) The relationship between a phenomenological approach (focusing on the subjective life of the patient) and empirical science, including neuroscience; (3) The nature of self-experience, especially in its pre-reflective form ("ipseity"—involving "operative intentionality"), and its possible disturbance in schizophrenia ("hyper-reflexivity" and "diminished self-affection"); (4) The relationship between self-disturbance in schizophrenia and disorders of both temporality and (what Husserl termed) "passive syntheses"; (5) The role of intentional or quasi-volitional processes in the perceptual (and other) disorders in schizophrenia; (6) The nature and diversity of phenomenology's potential contribution to the enterprise of "explanation"; and (7) The meaning of several concepts: "hermeneutic" or "existential" approach, phenomenological "reflection," and "negative symptoms.

Ensemble Decision Making System for Breast Cancer Data

Mining is a technique to extract the hidden knowledge of information. Among several data mining methods classification is especially useful in the field of medical diagnosis for decision making. In this study, a hybrid approach: CART decision tree classifier with feature selection and boosting ensemble method has been considered to evaluate the performance of classifier. Various Breast cancer data sets are considered for this study as breast cancer is one of the leading causes of death in women.
Assistive Technology-based Programs for Promoting Independence of Post-coma Children

Post-coma children usually fail to be constructively engaged with their surrounding environment, due to extensive motor disabilities and lack of speech. In fact, they may pose serious challenges to daily life contexts (i.e., home, medical and rehabilitative settings), since they are frequently unable to correctly manage the positive stimulation by their-own and they are inadequate to be involved within conventional and traditional programs [1,2]. Thus, these children may be not capable of: (a) regulate the amount and the type of stimulation available, and (b) positively interact or communicate with their partners (e.g., parents and caregivers), with negative outcomes on their quality of life [3,4]. To overcome this issue one may resort on assistive technology-based interventions (AT) [5]. AT refers to any device, equipment or piece enabling a participant affected by severe to profound developmental disabilities with self-determination towards the outside stimuli [6].
Astigmatism Occurring in Association with Pediatric Eye Disease

ABSTRACT Retrospective clinical data from 496 eyes of 256 children attending a low vision clinic were analyzed to determine the relation between different classes of disease that involve visual image degradation and astigmatism. Control data comprised refractions from 79 normal vision children. Children were classified into groups according to the category of disease (14 groups) and the reported age‐of‐onset of their visual disability (0 to 13 years, 5 groups). The mean astigmatism for all groups of children with low vision was larger than that of the normals and in most cases the difference was significant at the 95% level. Astigmatism was highest in children with albinism, retinitis pigmentosa, and idiopathic nystagmus. Increased prevalance of astigmatism compared to normals was noted in children having their onset of low vision as late as 13 years of age. In the low vision subjects with‐the‐rule astigmatism occurred more frequently than oblique or against‐the‐rule astigmatism and oblique astigmatism more frequently than against‐therule astigmatism.
Sporting Excellence, Schools and Sports Development: The Politics of Crowded Policy Spaces

The increased emphasis on the pursuit of elite international sporting achievement has inevitably meant that the role of the education system in England and Wales, and schools in particular, in contributing to elite success has been the subject of considerable debate and a focus for government intervention. Yet school sport remains a highly contested policy area subject to pressure from a range of, often competing, sectoral interests such as education, welfare and elite sports development. The focus of this paper is first to consider how the policymaking process for school sport might be theorized and second to illustrate the theorization through an examination f one recent policy initiative: specialist sports colleges. The discussion explores the degree to which the formulation of the specialist sports colleges initiative represented a compromise between competing sectoral interests and also the extent to which competing interests have affected policy during the early stages of implementation.
Pragmatic functions of prosodic features in non-lexical utterances

In informal English dialog many utterances are not composed of words, but are non-lexical items, such as uh-huh, um, and hmm. In non-lexical utterances much of the meaning is conveyed by prosody, rather than by the phonetic content. However the pragmatic functions of prosody in non-lexical utterances have not been much studied. Based on examination of 316 tokens in a conversation corpus, this paper identifies some common pragmatic functions for syllabification, duration, loudness, pitch height, pitch slope, and creaky voice in non-lexical utterances. While the evidence is eclectic and the investigation has been unsystematic, it seems that each of these prosodic features bears a fairly consistent core meaning.
TESTING MODELS OF FACULTATIVE SEX RATIO ADJUSTMENT IN THE POLLINATING FIG WASP PLATYSCAPA AWEKEI

Female hymenoptera are renowned for their ability to adjust offspring sex ratio to local mate competition. When two females share a patch, they frequently produce clutches that differ in size, the female with the larger clutch optimally producing a more female‐biased sex ratio and vice versa. Females can base their sex allocation on their own clutch size only (“self‐knowledge”) or on both females’ clutch sizes (“complete knowledge”). Few studies have genotyped offspring so that each mother's contribution can be considered separately while none has found that both sources of information are used simultaneously. We genotyped 2489 wasps from 28 figs and assigned their maternity to one of the two foundress females. We argue that likelihood is a very convenient method to compare alternative models, while fitness calculations help to appreciate the cost of maladaptation. We find that the pollinating fig wasp Platyscapa awekei simultaneously uses its own as well as the other females clutch size in allocating sex. Indeed, the complete knowledge model explains the data 36 times better than the self‐knowledge model. However, large clutches contained fewer males than the optimal predictions leading to a median selection coefficient of 0.01.
A cognitive theory for affective user modelling in a virtual reality educational game

The educational community in general considers computer-assisted learning to be very beneficial. As a result, numerous new educational software applications are being developed. An educational application can become very effective if it is adaptive and individualised to the student. However, one important aspect of students that has been overlooked so far, and should be included in such individualisation models, is students' behaviour and emotional state that affects their learning. This paper describes how system observations of students' behavioural characteristics, during their interaction with an educational application, may provide important evidence about students' emotions while they learn. The information collected from these observations mainly concerns students' behaviour while using the application, combined with students' reactions and responds to questions depending on the correctness of their answers. The system's inferences about students' emotions are used to adapt interaction to each individual student's needs taking into account their character and mood.
Volumetric analysis of syringomyelia following hindbrain decompression for Chiari malformation Type I: syringomyelia resolution follows exponential kinetics.

OBJECT Resolution of syringomyelia is common following hindbrain decompression for Chiari malformation, yet little is known about the kinetics governing this process. The authors sought to establish the volumetric rate of syringomyelia resolution. METHODS A retrospective cohort of patients undergoing hindbrain decompression for a Chiari malformation Type I with preoperative cervical or thoracic syringomyelia was identified. Patients were included in the study if they had at least 3 neuroimaging studies that detailed the entirety of their preoperative syringomyelia over a minimum of 6 months postoperatively. The authors reconstructed the MR images in 3 dimensions and calculated the volume of the syringomyelia. They plotted the syringomyelia volume over time and constructed regression models using the method of least squares. The Akaike information criterion and Bayesian information criterion were used to calculate the relative goodness of fit. The coefficients of determination R(2) (unadjusted and adjusted) were calculated to describe the proportion of variability in each individual data set accounted for by the statistical model. RESULTS Two patients were identified as meeting inclusion criteria. Plots of the least-squares best fit were identified as 4.01459e(-0.0180804)(x) and 13.2556e(-0.00615859)(x). Decay of the syringomyelia followed an exponential model in both patients (R(2) = 0.989582 and 0.948864). CONCLUSIONS Three-dimensional analysis of syringomyelia resolution over time enables the kinetics to be estimated. This technique is yet to be validated in a large cohort. Because syringomyelia is the final common pathway for a number of different pathological processes, it is possible that this exponential only applies to syringomyelia related to treatment of Chiari malformation Type I.
Usage Experience with Decision Aids and Evolution of Online Purchase Behavior

This study investigates how prior usage experience with various decision aids available in an Internet shopping environment contributes to online purchase behavior evolution. Four types of decision aids are examined: those for 1 nutritional needs, 2 brand preference, 3 economic needs, and 4 personalized shopping lists. We construct and estimate nonhomogeneous hidden Markov models of store-and category-level purchase decisions, in which parameters vary over time across hidden states as driven by usage experience with different decision aids. We find that consumers evolve through distinct behavioral states over time, and the evolution is attributable to their prior usage experience with various decision aids. Moreover, the impact varies by the specific decision aid, behavioral state, and category characteristics. In addition, consumers gravitate toward habitual decision processes in online grocery stores, and their average price and promotion sensitivities increase first and then decrease but the level of heterogeneity rises continuously. We identify beneficial versus potentially undesirable decision aids and demonstrate how the proposed research method can help online retailers improve their store environments, design customized promotions, and quantify the payoffs of these strategies.
