Data stream mining in ubiquitous environments: state‐of‐the‐art and current directions
Authors: Gaber Mohamed Medhat , Gama João , Krishnaswamy Shonali , Gomes João Bártolo , Stahl Frederic 
Published: February 2014

In this article, we review the state‐of‐the‐art techniques in mining data streams for mobile and ubiquitous environments. We start the review with a concise background of data stream processing, presenting the building blocks for mining data streams. In a wide range of applications, data streams are required to be processed on small ubiquitous devices like smartphones and sensor devices. Mobile and ubiquitous data mining target these applications with tailored techniques and approaches addressing scarcity of resources and mobility issues. Two categories can be identified for mobile and ubiquitous mining of streaming data: single‐node and distributed. This survey will cover both categories. Mining mobile and ubiquitous data require algorithms with the ability to monitor and adapt the working conditions to the available computational resources. We identify the key characteristics of these algorithms and present illustrative applications. Distributed data stream mining in the mobile environment is then discussed, presenting the Pocket Data Mining framework. Mobility of users stimulates the adoption of context‐awareness in this area of research. Context‐awareness and collaboration are discussed in the Collaborative Data Stream Mining, where agents share knowledge to learn adaptive accurate models.This article is categorized under:

Multilinear and nonlinear generalizations of partial least squares: an overview of recent advances
Authors: Zhao Qibin , Zhang Liqing , Cichocki Andrzej 
Published: February 2014

Partial least squares (PLS) is an efficient multivariate statistical regression technique that has shown to be particularly useful for analysis of highly collinear data. To predict response variablesYbased independent variablesX,PLSattempts to find a set of common orthogonal latent variables by projecting bothXandYonto a new subspace respectively. As an increasing interest in multi‐way analysis, the extension to multilinear regression model is also developed with the aim to analyzing two‐multidimensional tensor data. In this article, we overview thePLS‐related methods including linear, multilinear, and nonlinear variants and discuss the strength of the algorithms. As canonical correlation analysis (CCA) is another similar technique with the aim to extract the most correlated latent components between two datasets, we also briefly discuss the extension ofCCAto tensor space. Finally, several examples are given to compare these methods with respect to the regression and classification techniques.This article is categorized under:Technologies > Machine LearningTechnologies > Prediction

AbstractOrdered nanoporous structures are among the most fascinating and industrially important materials currently in use. The archetypal zeolite material has now been joined by an eclectic array of new structures that exhibit porosity over a wide range of length scales and with order/disorder expressed in a multitude of ways. This raises the bar in terms of characterization and extends a real challenge to the scientific community to fully understand the properties and potential future applications of such materials. In this review we discuss the importance of modern microscopy tools combined with diffraction in this endeavour and show how the details of even the most complex quasi‐crystalline nanoporous architectures can be elucidated. We show by using the appropriate spherical aberration (Cs) corrections in scanning transmission electron microscopy it is possible to decipher all the individual silicon and aluminum atoms in a zeolite structure. Automated routines for using large electron diffraction datasets for crystal structure determination of nanocrystals is described making the need for large single crystal synthesis less‐and‐less important. The power of complementary combinations of surface tools such as atomic force microscopy and high‐resolution scanning electron microscopy is discussed to elucidate crystal growth mechanisms. For mesoporous materials synthesized from self‐organized organic mesophases electron microscopy reveals the details of the complex hierarchy of porosity so crucial for the functional performance of the structure.
Synthesis, and Electrochemical and Density Functional Studies of New Copper(II)‐ and Manganese(II) Oxicam Drugs. Redox Potentials and MOs Compatible with SOD‐like Activity and Unusual Six‐membered Rings of Water Molecules Bridging Complex Units

Published: February 2014

AbstractThe synthesis and rare structures of MnII and CuII complexes with OXI drugs (oxicam, a family of non‐steroidal anti‐inflammatory drugs) are reported. On mixing MnII acetate with piroxicam (H2PIR) pale yellow single crystals of trans,trans‐[MnII(O‐N,N‐DMF)2(N,O‐HPIR)2], 1, dimethylformamide (DMF), were obtained. The structure shows two HPIR– anions chelate through pyridyl nitrogen and amide oxygen, and two positions around the metal atom are occupied by the two DMF molecules. The Mn–O(amide, HPIR) vector is much shorter than the two other coordination vectors, a novelty for MII(L)2(HOXI)2 molecules. Single crystals of trans,trans‐[CuII(H2O)2(N,O‐HTEN)2]·4H2O·2DMF, 2, (H2TEN, tenoxicam,) were obtained by long storage from DMF solutions of CuII(HTEN)2 during loading smart synthetic hydrogels. Compound 2 is the first example for MII(HOXI)2 units, linked to H2O molecules ever reported, and extensive networks of H2O···OH2 hydrogen bonds and Cu···OH2 bonds that involve six member cycles of water molecules arranged as puckered rings bridging MII(HOXI)2 entities. Infrared bands related to amide groups for HOXI– ligands are significantly influenced by the strength of M–O bonds in agreement with bond length trends. Electrochemical studies for CuII(HTEN)2 in tetrahydrofuran are in agreement with a SOD‐like scavenger activity at least for superoxide oxidation to molecular oxygen, E°(CuII/CuI, SCE) –0.31V. Furthermore, density functional investigation at the gas phase reproduces well the structure for trans,trans‐[MnII(O‐DMF)2(N,O‐HPIR)2] sextuplet molecule and for trans,trans‐[CuII(H2O)2(N,O‐HTEN)2] doublet molecule. Even a model of the {CuII(HTEN)2(OH2)···(H2O)4···(H2O)CuII(HTEN)2} entity found for 2 is well reproduced by theory. The estimate stabilization energy brought about by the six water molecules ring between two CuII(HTEN)2 molecules is 69 kcal.

Published: February 2014

AbstractSingle phase cobalt disulfide (CoS2) nanoparticles were prepared by thermal decomposition of cobalt‐thiourea complex at a low temperature (400 °C). CoS2 nanoparticles exhibit ferromagnetic ordering at 122 K below which the temperature dependent resistivity of cold pressed nanoparticles deviates from metallic behavior and shows a broad maximum. Just below TC, it also exhibits a large magnetoresistance effect (6.5 %). A mixture of CoS and Co9S8 phases were obtained between the temperature interval 400 °C < T < 1000 °C. At 1000 °C, a pure bulk Co9S8 phase was obtained. It exhibits magnetic hysteresis typical of a ferromagnet at room temperature and a peak in magnetization at low temperature with a strong relaxation indicating possible spin glass state.
Ag1+xTlO2 (0.03 ≤ x ≤ 0.18), Novel Adaptations of the Delafossite Structure Type Featuring Subvalent Silver

Published: February 2014

AbstractA family of novel variations of the delafossite type of structure, Ag1+xTlO2, was synthesized and characterized. For three members the crystal structures were solved and refined on single crystal data: Ag1+αTlO2 [α = 0.18, P$\bar{3}$m1, Z = 1, a = 3.40427(9), c = 6.1296(1) Å, R1 = 0.033, 126 independent reflections]; Ag1+βTlO2 [β = 0.09, R$\bar{3}$m, Z = 6, a = 3.40685(8), c = 37.5953(9) Å, R1 = 0.039, 214 independent reflections]; Ag1+γTlO2 [γ = 0.03, R$\bar{3}$m, Z = 9, a = 3.403(2), c = 56.67(3) Å, R1 = 0.038, 397 independent reflections]. Different from the conventional delafossite structure, part of the silver layers accommodate an excess of ca. 0.18 silver atoms per layer, thus generating a subvalent bonding state of silver. In accordance with the structural findings, the new silver oxthallates(III) are metallic conductors, and show reduced binding energies for the silver 3d5/2 states, compared to silver(I) oxide.
An Investigation of Genetic Counselors’ Testing Recommendations: Pedigree Analysis and the Use of Multiplex Breast Cancer Panel Testing
Authors: Lundy Meghan G. , Forman Andrea , Valverde Kathleen , Kessler Lisa 
Published: February 2014

AbstractGenetic testing recommendations for hereditary breast and ovarian cancer involve pedigree analysis and consultation of testing guidelines. The testing landscape for hereditary cancer syndromes is shifting as multiplex panel tests become more widely integrated into clinical practice. The purpose of the current study was to assess how genetic counselors utilize pedigrees to make recommendations for genetic testing, to determine consistency of these recommendations with National Comprehensive Cancer Network (NCCN) Guidelines and to explore current use of multiplex panel testing. Sixty‐nine genetic counselors were recruited through the National Society of Genetic Counselors Cancer Special Interest Group's Discussion Forum. Participation involved pedigree analysis and completion of an online questionnaire assessing testing recommendations and use of multiplex panel testing. Pedigree analysis and test recommendations were scored for consistency with NCCN guidelines. The average score was 12.83/15 indicating strong consistency with NCCN guidelines. Participants were more likely to consider multiplex testing when pedigrees demonstrated highly penetrant dominant inheritance but were not indicative of a particular syndrome. Participant concerns about multiplex panel testing include limited guidelines for both testing eligibility and medical management. This study demonstrates high utilization of pedigree analysis and raises new questions about its use in multiplex genetic testing.

Published: February 2014

Purpose Different treatment modalities have been utilized to treat unicameral bone cyst (UBC), but evidence has not been fully described to support one treatment over another and the optimal treatment is controversial. The aim of this quantitative systematic review was to assess the effectiveness of different UBC treatment modalities. Methods We utilized Pubmed to isolate retrospective studies on patients with UBC who received any kind of treatment. The included studies needed to have a minimum sample size of 15 patients, and have provided data on radiographic healing outcome. Results Sixty-two articles were selected for the meta-analysis from a total of 463 articles. The cumulative sample size was 3,211 patients with 3,217 UBC, and male to female ratio was 2.2:1. The summary or pool estimate of methylprednisolone acetate (MPA) injection resulted in a healing rate of (77.4 %) that was comparable to bone marrow injection (77.9 %). A higher healing rate was observed with MPA injection when inner wall disruption was performed. The pool estimate of bone marrow with demineralized bone matrix injection was high (98.7 %). UBC healing rate after surgical curettage was comparable whether autograft or allograft was utilized (90 %). UBC treatment with flexible intramedullary nails without curettage provided almost 100% healing rate, while continuous decompression with cannulated screws provided 89 % healing rate. Conservative treatment indicated a healing rate of 64.2, 95 % CI (26.7–101.8). Conclusions Active treatment for UBC provided variable healing rates and the outcomes were favorable relative to conservative treatment. Due to the heterogeneity of the studies and reporting bias, the interpretation of these findings should be handled with caution.

Authors: Marschall Sabine 
Published: February 2014

Abstract:This article investigates issues of identity construction and public memorialization in postapartheid South Africa. It focuses on theSunday TimesHeritage Project, a unique private-sector initiative that involved the installation of thirty memorials throughout the country between 2006 and 2008. The article discusses the conceptualization and implementation of the project, pointing out important differences between this private initiative and the state-directed heritage effort. By interrogating the nexus between race, space, and memory in the construction of memorials, the article highlights the significance of placement and location in the formation of new identity discourses.
RethinkingChimurengaandGukurahundiin Zimbabwe: A Critique of Partisan National History
Authors: Ndlovu-Gatsheni Sabelo J. 
Published: February 2014

Abstract:This article examines how the Zimbabwe African National Union-Patriotic Front (ZANU-PF) sought to inscribe a nationalist monologic history in Zimbabwe in order prop up its claim to be the progenitor and guardian of the postcolonial nation. Since its formation in 1963, it has worked tirelessly to claim to be the only authentic force with a sacred historic mission to deliver the colonized people from settler colonial rule. To achieve this objective, ZANU-PF has deployed the ideology ofchimurengain combination with the strategy ofgukurahundias well as a politics of memorialization to install a particular nationalist historical monologue of the nation. After attaining power in 1980, it proceeded to claim ownership of the birth of the nation. While the ideology ofchimurengasituates the birth of the nation within a series of nationalist revolutions dating back to the primary resistance of the 1890s, the strategy ofgukurahundientails violent and physical elimination of enemies and opponents. But this hegemonic drive has always encountered an array of problems, including lack of internal unity in ZANU-PF itself, counternarratives deriving from political formations like the Zimbabwe African People's Union (ZAPU); labor movements; and critical voices from the Matebeleland region, which fell victim togukurahundistrategy in the 1980s. With the formation of the Movement for Democratic Change (MDC) in 1999, which soon deployed democracy and human rights discourse to critique the ideology ofchimurengaand the strategy ofgukurahundi, ZANU-PF hegemony became extremely shaky and it eventually agreed to share power with the MDC in February 2009.
Minority Rights, Culture, and Ethiopia's “Third Way” to Governance
Authors: Barata Data Dea 
Published: February 2014

Abstract:Following a successful armed resistance against a dictatorial state regime, a new government of former rebels took control of the national state in Ethiopia in 1991. Prompted partly by unfolding sea changes in global politics in the early 1990s, the new Ethiopian government pledged to undertake radical governance reform. More than twenty years after the new government took office, contested assessments of its record vis-à-vis its human and minority rights pledge, among other issues, have generated waves of debate, criticism, controversy, and global protests. Based on observations from southern Ethiopia, this article takes an ethnographic look at both the process and the outcome of Ethiopia's experiment with ethnic self-government, with a special focus on understanding the value of minority rights as an ideological construct. Conceptually, the paper attempts to explain a disjuncture between the globally prescribed ideal of human/minority group rights and the realities of governance on the ground.

ABSTRACTAgeing is going to be a major problem in Bangladesh given its population size, scarce resources, existing poverty, insufficient health facilities and lack of a social security system. This paper examines how many years older people expect to be in good health, and what are the correlates of self-rated health (SRH). The data used in this study come from 896 older people aged 60 years and above from Rajshahi district in Bangladesh and from United Nations’ projected population figures. Results show that individuals at age 60 expected about 41 per cent of their remaining life to be in good health, while individuals at age 80 expected only 21 per cent of their remaining life to be in good health. Having exercised during the six months prior to the survey was the single most important correlate of SRH (odds ratio=5.49; confidence interval 4.03–7.47; without any adjustment). While rural–urban differentials and some health decline in old age are inevitable, four factors (exercise behaviour, sufficiency of income, physical limitations and facing abusive behaviour) are to a certain extent modifiable and therefore provide the potential for improving SRH and healthy life expectancy in Rajshahi district, Bangladesh.

SummaryThe Endangered Scaly-sided Merganser Mergus squamatus is amongst the most threatened of sea ducks (Mergini), with an estimated population of c.4,600 individuals based on a recent population estimate on the breeding areas in Primorye, Far East Russia, China and DPR Korea. For the first time, we present published and unpublished data on the wintering distribution in China and smaller numbers in Korea. We report 156 sightings during 2000–2011, together with 11 records of wintering sites using geolocation devices, from 16 provinces in China, with greatest concentrations in Jiangxi Province (97 reports from 18 sites). Both sources of data suggest some degree of winter site fidelity to fast-flowing clear water rivers 50–350 m wide, with riffles, islands or sand banks in hilly/mountainous areas with low levels of human disturbance. Surveys located a maximum of 370–770 birds, 8–17% of the estimated total population, confirming our poor knowledge of the species’ wintering distribution. There is an urgent need to define the wintering range of this species which is widely dispersed and nowhere abundant, but is threatened everywhere by dam construction, sand and gravel extraction, industrial and domestic pollution and fishing that threaten the integrity of the winter habitat. This also raises important conservation questions about how to protect such a species that is not highly concentrated and may require catchment scale nature conservation actions to effectively safeguard its current distribution.

Authors: Keenan Gayle I. G. , Hodgson Denyse A. 
Published: February 2014

AbstractsBackgroundService user involvement has been demonstrated as an important aspect of cancer professionals’ education. There is some understanding of service users’ incentive to be involved, but little insight into what motivates them. This study explores this concept more fully.PurposeTo explore the motivations and experience of service users’ involvement in radiotherapy and oncology education.Materials and methodsOne-to-one interviews were conducted with service users who have been involved in education at the university. Thematic analysis was conducted. Five participants were asked about their motivations and experience of taking part in a variety of educational activities.ResultsThe experience of being involved gave the participants a sense of wellbeing and purpose. Three sub-themes were identified that related to service users’ motivation for being involved in educational activities with undergraduate students. These were to promote awareness by sharing their experiences of cancer; improve patient care through learning from negative experience; and personal reward skills for survivorship.ConclusionsThis study has highlighted the importance of hearing the voice of the service users; a two-way engagement for which there are benefits for both the students and service users. The involvement of service users in education becomes part of their personal journey.

Published: February 2014

Background.The relative importance of traumatic events (TEs) in accounting for the social burden of post-traumatic stress disorder (PTSD) could vary according to cross-cultural factors. In that sense, no such studies have yet been conducted in the Spanish general population. The present study aims to determine the epidemiology of trauma and PTSD in a Spanish community sample using the randomly selected TEs method.Methods.The European Study of the Epidemiology of Mental Disorders (ESEMeD)-Spain is a cross-sectional household survey of a representative sample of adult population. Lifetime prevalence of self-reported TEs and lifetime and 12-month prevalence of PTSD were evaluated using the World Health Organization (WHO) Composite International Diagnostic Interview. Reports of PTSD associated with randomly selected TEs were weighted by the individual-level probabilities of TE selection to generate estimates of population-level PTSD risk associated with each TE.Results.Road accident was the most commonly self-reported TE (14.1%). Sexual assault had the highest conditional risk of PTSD (16.5%). The TEs that contributed most to societal PTSD burden were unexpected death of a loved one (36.4% of all cases) and sexual assault (17.2%). Being female and having a low educational level were associated with low risk of overall TE exposure and being previously married was related to higher risk. Being female was related to high risk of PTSD after experiencing a TE.Conclusions.Having an accident is commonly reported among Spanish adults, but two TE are responsible for the highest burden associated with PTSD: the unexpected death of someone close and sexual assault. These results can help designing public health interventions to reduce the societal PTSD burden.
