Authors: Frydrychová S , Lustyková A , Václavková E , Lipenský J , Rozkot M
Published: December 2015

The objective of this study was to investigate the effect of using different extenders viz. Androhep, Safecell Plus and SUS during cryopreservation on quality of frozen-thawed boar semen. Semen volume, sperm motility, sperm concentration, percentage of morphologically abnormal spermatozoa, total number of spermatozoa per ejaculate and activity of the enzyme aspartate aminotransferase (AST) were assessed in fresh semen collected from 39 fertile AI boars. Semen from each boar was divided into three portions and diluted 1:1.5 in extender Androhep, Safecell Plus and SUS and keep at 17°C for 15-h holding time before cryopreservation. Then sperm was cryopreserved. Straws were thawed in a water bath at 38°C for 40s and post-thaw sperm motility with AST activity was assessed. Significant difference in post-thaw sperm motility was found between extender Androhep and Safecell Plus (P<0.05). AST activity did not differ significantly between tested extenders (P>0.05). In conclusion, the results of the study indicate that using Safecell Plus extender during holding period before cryopreservation significantly affected post-thaw sperm motility.

Published: December 2015

Sixty healthy ovaries were collected from local slaughter house. Oocytes from small and medium sized follicles (2-8 mm in diameter) were selected for oocyte collection using aspiration followed by slicing . A and B category ( cumulus oocyte complexes (COCs) with more than 5 layers and 3-5 layers respectively of compact cumulus cells surrounding the zona pellucida) were selected for in vitro maturation. A total of 361 oocytes were found to be matured with overall mean maturation rate of 82.59 ± 0.02%. The mean number of grade A, B and C oocytes recovered per ovary was 4.26 ± 0.53, 3.05 ± 0.31 and 1.25 ± 0.19, respectively. The overall recovery of grade A, B and C oocytes were 256, 183 and 74 . Out of 439 oocytes 58.86 ± 0.05%, 33.23 ±0.04 % and 9.90 ± 0.04 % showed +++, ++ and + degrees of cumulus expansion, respectively. It was concluded that aspiration followed by slicing is an ideal method for maximum yield of oocytes and in vitro maturation in indigenous cow of Assam.
A Educação Apinayé: resultados de oficinas e observações na escola Mariazinha
The Apinayé Education: results of workshops and observations at school Mariazinha
Authors: Borges Thelma Pontes , Pacifico Filho Miguel
Published: December 2015

A escolha dos povos Apinayé e da escola Mariazinha ocorreu por conta da publicidade nacional do péssimo resultado desta escola na prova do ENEM/2009. Por conta de um interesse bilateral, tanto nosso como dos professores indígenas de tentar entender o ocorrido, realizou-se durante uma semana uma série de atividades que permitissem identificar fatores de compreensão desta situação. Dessa forma, entre as atividades previstas realizamos uma oficina de grupo, que tinha como objetivo mobilizar os professores indígenas e não indígenas para que estes pudessem identificar questões ligadas ao processo educativo, de funcionamento da escola/aldeia. Após o trabalho chegamos a algumas categorias propostas pelo grupo: alfabetização e currículo; divergências entre os professores índios e não índios; professor polivalente; professor indígena; falta de material didático e de apoio; transporte, estrutura e recursos; trabalho infantil; alcoolismo e doenças sexualmente transmissíveis. Apesar de percebermos algumas medidas na tentativa de reversão destes problemas, existe a necessidade de se buscar uma integração entre a comunidade indígena, professores não índios e governos, na tentativa de tornar o espaço-subjetivo escolar em local de construção de representações do povo apinayé, auxiliando na identidade de sua cultura, no fortalecimento de sua língua e na mediação dos debates políticos.
Os objetivos constitucionais de preparo para o exercício da cidadania ativa em contexto de declínio do cidadão participativo no Estado Democrático de Direito
Constitutional objectives for preparation to exercise an active citizenship in a context of declining participative citizens in Democratic State of Law
Authors: Berardi Regina Celli Marchesini
Published: December 2015

O presente artigo trata da importância da participação política (como expressão da cidadania) para a democracia e da educação como um dos instrumentos para promover a participação política. Este estudo surge face à preocupação com a apatia e o desinteresse pela participação e pelas coisas públicas, com o escopo de contribuir para a reflexão sobre o papel da educação, sobretudo por meio da educação cívica escolar, na formação do cidadão participativo, condição imprescindível para a sedimentação do regime democrático. A proposta fundamenta-se nas exigências constitucionais de preparo para a cidadania e a participação, as quais tem a cidadania como um dos fundamentos do Estado Democrático de Direito. Abordar-se-ão os temas de “cidadania”, “participação política”, “democracia” e “educação formal básica”, para discutir se o direito à educação, conforme está garantido nas Constituições Brasileira é suficiente e adequado para atingir o objetivo da participação política ou, se é necessária uma educação política específica, que vá além da mera instrução fornecida pelos Estados para a efetiva promoção da cidadania ativa.

Published: December 2015

Este estudo tem propósito de analisar a percepção de profissionais do gênero feminino em relação aos indicadores da abordagem biopsicossocial e organizacional (BPSO-96) de Qualidade de Vida no Trabalho. Metodologicamente, empreendeu-se de uma pesquisa de caráter descritivo e quantitativo do tipo survey, sendo utilizado o instrumento BPSO-96 adaptado de Limongi-França (1996), aplicado a 352 trabalhadoras de diferentes organizações de um munícipio da Região Sul do Brasil. Os resultados evidenciaram que a formação dos fatores se apresentou diferente do previsto no BPSO-96, o que pode estar relacionado às inúmeras mudanças sociais e organizacionais da atualidade. Em relação aos aspectos organizacionais, os indivíduos apresentam índices mais elevados de alta QVT. Entretanto, a avaliação geral da união dos três fatores que caracteriza a abordagem psicossocial, evidencia avaliação de nível médio por parte das respondentes. Ainda, foi possível identificar que as profissionais da categoria serviços não humanos apresentam níveis de QVT elevado e aquelas da categoria serviços humanos demonstraram maior insatisfação com os aspectos organizacionais, bem como, as que afirmam gostar de sua função apresentam alta QVT e as que não gostam de sua função possuem baixa QVT.

Historical data reveal fish assemblage shifts in an unregulated prairie river
Authors: Senecal Anna C. , Walters Annika W. , Hubert Wayne A.
Published: December 2015

Wyoming's Powder River is considered an example of a pristine prairie river system. While the river hosts a largely native fish assemblage and remains unimpounded over its 1,146‐km course to the Yellowstone River confluence, the hydrologic regime has been altered through water diversion for agriculture and natural gas extraction and there has been limited study of fish assemblage structure. We analyzed fish data collected from the mainstem Powder River in Wyoming between 1896 and 2008. Shifts in presence/absence and relative abundance of fish species, as well as fish assemblage composition, were assessed among historical and recent samples. The recent Powder River fish assemblage was characterized by increased relative abundances of sand shiner Notropis stramineus and plains killifish Fundulus zebrinus, and decreases in sturgeon chub Macrhybopsis gelida. Shifts in fish species relative abundance are linked to their reproductive ecology with species with adhesive eggs generally increasing in relative abundance while those with buoyant drifting eggs are decreasing. Assemblage shifts could be the result of landscape level changes, such as the loss of extreme high and low flow events and changing land use practices.

The relationship between selection at coarse and fine spatiotemporal spatial scales is still poorly understood. Some authors claim that, to accommodate different needs at different scales, individuals should have contrasting selection patterns at different scales of selection, while others claim that coarse scale selection patterns should reflect fine scale selection decisions. Here we examine site selection by 110 woodland caribou equipped with GPS radio‐collars with respect to forage availability and predation risk across a broad gradient in availability of both variables in boreal forests of Northern Ontario. We tested whether caribou selection for forage and avoidance of risk was consistent between coarse (seasonal home range) and fine scales of selection. We found that local selection patterns predicted coarse scale selection patterns, indicating a close relationship between the drivers of selection at both spatial scales.
Changepoint analysis: a new approach for revealing animal movements and behaviors from satellite telemetry data

Published: December 2015

While telemetry is an invaluable tool for tracking animal movement patterns, the data generated by this technique is often challenging to interpret. Here, we addressed this issue by developing a novel method, based on changepoint analysis, which incorporated both the horizontal and vertical movement metrics and compared this output to that from a switching state‐space model (SSSM) that categorized behavior based on horizontal movement metrics. We deployed 20 satellite transmitters on postnesting loggerhead turtles at Rethymno, Crete, Greece between 2010 and 2011 to monitor their at‐sea behavior. We used both models to identify behavioral changes, such as the switches from migration to foraging, and from foraging to overwintering. The satellite‐tracked turtles exhibited three discrete migratory strategies, with 9 turtles migrating southwards to the coast of northern Africa, 6 turtles migrating northwards into the Aegean Sea, and 4 turtles remaining resident in the waters of Crete. The SSSM readily identified the switch from transiting to ARS behavior in most animals, but the CPA model was able to distinguish multiple modes and more subtle shifts in behavior corresponding with shifts from migration to foraging to overwintering behaviors. We have shown that by incorporating vertical movement metrics into the analysis of telemetry data, previously hidden shifts in behavior can be revealed. The resulting increase in ability to discern complex behavioral patterns of animals remotely will likely yield better management and conservation decisions for a wide array of organisms.
Disentangling the influence of abiotic variables and a non‐native predator on freshwater community structure
Authors: Pagnucco Katie S. , Ricciardi Anthony
Published: December 2015

Cause‐and‐effect interpretations of the apparent impacts of biological invasions are confounded by the coincident occurrence of non‐native species and changes to abiotic factors. Native community structure and function can vary greatly in space and time, owing to abiotic variables that could potentially be affected by non‐native species. Here, we sought to determine the relative importance of abiotic variables and an invasive predatory fish, the Eurasian round goby (Neogobius melanostomus), on local macroinvertebrate assemblages and benthic algal production in the St. Lawrence River. We used structural equation modeling to evaluate the strength of interaction pathways between hypothesized biotic and abiotic factors driving trophic cascades. Our results indicate that biotic interactions with the round goby drive changes in the abundances of native grazers and non‐native dreissenid mussels in the St. Lawrence River. However, the directionality of these effects contradicts previous studies of round goby impacts that emphasized top‐down control. We found positive correlations between round goby density and prey (dreissenid and grazer) densities, suggesting complex interactions between round gobies and benthic communities, including strong bottom‐up forces. Together with previous studies, our results suggest that, although the interactions between round gobies and benthic communities remain strong, the direction of these interactions varies over space and time. Our results highlight the importance of disentangling the respective roles of biotic interactions and abiotic factors, in order to properly assess the impacts of non‐native species as well as the spatiotemporal variability of such impacts.
Uloga stresora na radu i iracionalnih uverenja u predikciji nastavničkog stresa
Authors: Popov Stanislava , Popov Boris , Damjanović Rade
Published: December 2015

Prema teoriji Racionalno emotivno bihejvioralne terapije (REBT), iracionalna uverenja predstavljaju uzročne mehanizme uključene u nastanak psiholoških poremećaja i problema (David, Freeman, & DiGiuseppe, 2009). U praksi postoji razvijen sistem konsultativnog rada sa nastavnicima, zasnovan na identifikaciji i osporavanju specifičnih iracionalnih uverenja (Bora, Bernard, Trip, Decsei-Radu, & Chereji, 2009; Terjesen & Kurasaki, 2009). Dosadašnja istraživanja u ovoj oblasti su se ticala psihometrijske operacionalizacije iracionalnih uverenja nastavnika, kao i vezom između tih uverenja i nastavničkog stresa (Bora et al., 2009). Mi pretpostavljamo da osim uverenja postoje i specifični organizacijski izvori stresa u školama koji utiču na nivo nastavničkog stresa. Cilj ovog istraživanja bio je ispitivanje veze između izvora stresa na radu (u školama), specifičnih iracionalnih uverenja i nivoa psihološkog distresa kod nastavnog osoblja. Uzorak u istraživanju činilo je 186 nastavnika i učitelja oba pola, iz osnovnih i srednjih škola sa teritorije Zrenjanina i Sombora (Vojvodina). Prosečna starost ispitanika je 40 godina. Instrumenti korišćeni za prikupljanje podataka su: Skala nastavničkih iracionalnih uverenja (The Teacher Irrational Belief Scale – TIBS), Izvori radnog stresa (IRS) i Skala depresivnosti, anksioznosti i stresa (Depression, Anxiety and Stress Scale – DASS-21). Za obradu podataka korišćeno je strukturalno modelovanje. Rezultati ukazuju da i stresori na radu i iracionalna uverenja imaju direktnog uticaja na distres. Uverenja, dakle, predstavljaju parcijalne medijatore u ovoj vezi. To je očekivan rezultat koji je objašnjen razlikovanjem 'zdravog' i 'nezdravog' emocionalnog odgovora u REBT teoriji i praksi.
Perfekcionizam - pozitivna ili negativna osobina? relacije sa subjektivnim blagostanjem, optimizmom i pesimizmom
Authors: Panić Damjana , Radojković Dragana , Hadži Pešić Marina
Published: December 2015

Cilj ovog istraživanja bio je da se ispita odnos pozitivnog i negativnog perfekcionizma sa subjektivnim blagostanjem i proveri medijatorska uloga optimizma i pesimizma kao kognitivnih mehanizama u ovom odnosu. Prema dvoprocesnom modelu perfekcionizma postoje razlike u kognitivnom funkcionisanju pozitivnih i negativnih perfekcionista, što posledično dovodi do različitih, pozitivnih ili negativnih ishoda. U istraživanju je učestvovalo 287 studenata Univerziteta u Nišu, ujednačenih po polu. Utvrđeni rezultati generalno podržavaju postavke dvoprocesnog modela da perfekcionizam ima i pozitivna i negativa svojstva i ukazuju da su njegovi pozitivni i negativni aspekti različito povezani sa subjektivnim blagostanjem. Nalazi takođe upućuju da se odnos pozitivnog perfekcionizma i subjektivnog blagostanja ostvaruje delimično preko optimizma, dok je veza negativnog perfekcionizma i subjektivnog blagostanja potpuno posredovana optimizmom i pesimizmom kao medijatorima. Čini se da generalni način razmišljanja koji usvajaju može da zaštiti, ali isto tako i da hendikepira perfekcioniste u pogledu ishoda aktivnosti koje preduzimaju, i na taj način doprinese višem, tj. nižem nivou subjektivnog blagostanja. U narednim istraživanjima bi bilo značajno ispitati i druge mehanizme koji mogu imati medijacionu ulogu između perfekcionizma i subjektivnog blagostanja, ali i drugih indikatora mentalnog zdravlja.

Authors: Hagiwara Megan Kiyomi Inada , Miyamura Jill , Yamada Seiji , Sentell Tetine
Published: December 2015

Objectives. We compared the age at admission and the severity of illness of hospitalized Micronesians with 3 other racial/ethnic groups in Hawaii.

Methods. With Hawaii Health Information Corporation inpatient data, we determined the age at admission and the severity of illness for 162 152 adult, non–pregnancy-related hospital discharges in Hawaii from 2010 to 2012. We performed multivariable linear regression analyses within major disease categories by racial/ethnic group. We created disease categories with all patient refined–diagnosis related groups.

Results. Hospitalized Micronesians were significantly younger at admission than were comparison racial/ethnic groups across all patient refined–diagnosis related group categories. The severity of illness for Micronesians was significantly higher than was that of all comparison racial/ethnic groups for cardiac and infectious diseases, higher than was that of Whites and Japanese for cancer and endocrine hospitalizations, and higher than was that of Native Hawaiians for substance abuse hospitalizations.

Conclusions. Micronesians were hospitalized significantly younger and often sicker than were comparison populations. Our results will be useful to researchers, state governments, and hospitals, providers, and health systems for this vulnerable group.
Integrating Systems Science and Community-Based Participatory Research to Achieve Health Equity
Authors: Frerichs Leah , Lich Kristen Hassmiller , Dave Gaurav , Corbie-Smith Giselle
Published: December 2015

Unanswered questions about racial and socioeconomic health disparities may be addressed using community-based participatory research and systems science. Community-based participatory research is an orientation to research that prioritizes developing capacity, improving trust, and translating knowledge to action. Systems science provides research methods to study dynamic and interrelated forces that shape health disparities. Community-based participatory research and systems science are complementary, but their integration requires more research. We discuss paradigmatic, socioecological, capacity-building, colearning, and translational synergies that help advance progress toward health equity.
Physical Activity and Dietary Determinants of Weight Loss Success in the US General Population
Authors: Wilson Patrick
Published: December 2015

Objectives. I studied lifestyle behaviors of long-term weight losers in a nationally representative sample.

Methods. I categorized the dietary and physical activity data of 8012 adults from the 2009–2012 National Health and Nutrition Examination Surveys into (1) long-term weight losers (≥ 10% loss for ≥ 1 year), (2) recent weight losers (≥ 10% loss within past year), and (3) overweight or obese individuals who never lost 10% or more of their weight.

Results. Long-term weight losers consumed fewer calories (2072; 95% confidence interval [CI] = 2011, 2134 kcal vs 2211; 95% CI = 2173, 2249 kcal; P < .001) and were more likely to report any vigorous leisure activity (24.5% vs 20.3%; P = .027) than did overweight or obese individuals. Among those engaging in vigorous leisure activity, long-term weight losers reported a greater quantity (188; 95% CI = 159, 223 min × wk–1 vs 156; 95% CI = 142, 172 min × wk–1; P = .047). Recent weight losers did not differ from overweight or obese individuals on absolute calorie intake but reported less fat (79; 95% CI = 75, 83 g vs 84; 95% CI = 82, 86 g; P = .016) and more activity.

Conclusions. Balanced calorie restriction from all macronutrients and physical activity are important behaviors for successful long-term weight loss in the general population.
Child-Resistant Packaging for E-Liquid: A Review of US State Legislation
Authors: Frey Leslie T. , Tilburg William C.
Published: December 2015

A growing number of states have introduced or enacted legislation requiring child-resistant packaging for e-liquid containers; however, these laws involve varying terms, packaging standards, and enforcement provisions, raising concerns about their effectiveness. We evaluated bills against 4 benchmarks: broad product definitions that contemplate future developments in the market, citations to a specific packaging standard, stated penalties for violations, and express grants of authority to a state entity to enforce the packaging requirements. Our findings showed that 3 states meet all 4 benchmarks in their enacted legislation. We encourage states to consider these benchmarks when revising statutes or drafting future legislation.

Published: December 2015

We examined initiation patterns among different birth cohorts of people who used prescription opioids and heroin because of historical differences in drug use availability. We examined data from a community-based study of persons who inject drugs (n = 483) in California and a general population survey from the National Survey on Drug Use and Health (n = 1264) and found that individuals born after 1980 were more likely than were individuals born before 1980 to initiate opioids through nonmedical use of prescription opioids than heroin.
The Implications of Unintended Pregnancies for Mental Health in Later Life
Authors: Herd Pamela , Higgins Jenny , Sicinski Kamil , Merkurieva Irina
Published: December 2015

Despite decades of research on unintended pregnancies, we know little about the health implications for the women who experience them. Moreover, no study has examined the implications for women whose pregnancies occurred before Roe v. Wade was decided—nor whether the mental health consequences of these unintended pregnancies continue into later life. Using the Wisconsin Longitudinal Study, a 60-year ongoing survey, we examined associations between unwanted and mistimed pregnancies and mental health in later life, controlling for factors such as early life socioeconomic conditions, adolescent IQ, and personality. We found that in this cohort of mostly married and White women, who completed their pregnancies before the legalization of abortion, unwanted pregnancies were strongly associated with poorer mental health outcomes in later life.
When Emotional Intelligence Affects Peoples’ Perception of Trustworthiness
Authors: Lee Wing Shing , Selart Marcus
Published: December 2015

By adopting social exchange theory and the affect-infusion-model, the hypothesis is made that emotional
intelligence (EI) will have an impact on three perceptions of trustworthiness – ability, integrity and benevolence – at the
beginning of a relationship. It was also hypothesized that additional information would gradually displace EI in forming
the above perceptions. The results reveal that EI initially does not contribute to any of the perceptions of trustworthiness.
As more information is revealed EI has an impact on the perception of benevolence, but not on the perceptions of ability
and integrity. This impact was observed to be negative when the nature of the information was negative. On the other
hand, information alone was shown to have a significant impact on the perceptions of ability and integrity, but not on the
perception of benevolence. Theoretical and practical implications of the findings are addressed.

Authors: Ilina N.G. , Krinitsyna Yu M. , Denisov M. Yu. , Sergeeva I.G.
Published: December 2015

Background: Specific sensitization characterizes increased serum level of IgE to different groups of allergens
(food, dust, domestic and contact). Characteristic of specific sensitization changes with age of patient. Spectrum of
specific sensitization determined environmental factors, conditions of habitation.

Objective: objective was to research characteristic of specific sensitization in patients with atopic dermatitis.

Methods: There were 108 patients with atopic dermatitis, 1st group – 31 patient (17 boys and 14 girls) 0-3y.o., 2nd group
– 30 (13 boys and 17 girls) 4-13 y.o., 3rd group – 47 (16 men and 31 women) 16-63 y.o. In control group, there were 25
patients (4 men, 21 women) 16-64 y.o. with another dermatological diseases such as psoriasis, acne, rosacea and etc.,
without atopic dermatitis. In patients of all 4 groups evaluated personal, family allergic anamnesis, drug and food allergy,
sensitization by measuring common and specific levels of immunoglobulin E.

Results: 10%, 32%, 27% patients of 1st, 2nd, 3rd groups had food allergy. The main allergens were citruses (37% cases),
chocolate (27%) and milk (17%).

Conclusion: 44-52% patients with atopic dermatitis and 4% patients without atopy had non-specific sensitization, that
characterized five-fold increased serum level of IgE and more.

50-60% patients with atopic dermatitis had specific sensitization. 60% infants at the age under 3 y.o. with atopic
dermatitis had sensitization for epithelium of homepets, 50% - for milk, 30% - white-egg. Among adults with atopic
dermatitis sensitization was the same, as in control group. 35% patients with dermatoses without atopy had specific
sensitization.

Examining “Equitable” Retention
Authors: Richardson Lorna
Published: December 2015

The operation of compensation, whereby a liquid debt reduces or extinguishes a liquid debt, is well understood, as is retention of a sum due under a contract on the principle of mutuality. Less understood is the doctrine of retention of debts, the so-called “other type of retention” or “equitable” retention discussed in obiter remarks by Lord Rodger in the UK Supreme Court decision in Inveresk plc v Tullis Russell Papermakers Ltd [2010] UKSC 19. This form of “equitable” retention is the subject of a detailed study by Lorna Richardson in this article.

We report on the frequency doubling of femtosecond laser pulses at 1030 nm center wavelength generated from the fully diode-pumped laser system POLARIS. The newly generated pulses at a center wavelength of 515 nm have a pulse energy of 3 J with a pulse duration of 120 fs. On the basis of initially ultra-high contrast seed pulses we expect a temporal intensity contrast better 10 17 200 ps before the peak of the main pulse. We analyzed the temporal intensity contrast from milliseconds to femtoseconds with a dynamic range covering more than 20 orders of magnitude. The pulses were focussed with a f/2-focussing parabola resulting in a peak intensity exceeding 10 20 W / cm 2 . The peak power and intensity are to the best of our knowledge the highest values for 515 nm-laser-pulses achieved so far.
Switching off H2O2 Decomposition during TS-1 Catalysed Epoxidation via Post-Synthetic Active Site Modification
Authors: Hammond Ceri , Tarantino Giulia
Published: December 2015

Despite its widespread use, the Lewis acidic zeolite, TS-1, still exhibits several unfavourable properties, such as excessive H2O2 decomposition, which decrease its overall performance. In this manuscript, we demonstrate that post-synthetic modification of TS-1 with aqueous NH4HF2 leads to modifications in epoxidation catalysis, which both improves the levels of epoxide selectivity obtained, and drastically minimises undesirable H2O2 decomposition. Through in situ spectroscopic study with UV-resonance enhanced Raman spectroscopy, we also observe a change in Ti site speciation, which occurs via the extraction of mononuclear [Ti(OSi)4] atoms, and which may be responsible for the changes in observed activity.

Published: December 2015

Given its unpredictable nature, urban sprawl in the Mediterranean region is considered an intriguing (and intricate) socioeconomic issue. Since the 1970s, urban dispersion advanced rapidly in southern Europe—irrespective of a city’s size and morphology—with urbanization rates growing faster than population. A comparison between the metropolitan areas of Barcelona, Rome and Athens reveals how sprawl has occurred in different ways in the three cities, highlighting peculiar relationships between urbanization, land-use and economic structures. Sharing common drivers of change related to population dynamics, socio-spatial structure and deregulated urban expansion, sprawl has adapted to the local economic, cultural and environmental context. Barcelona shows a dispersion pattern towards a more spatially-balanced morphology, with expanding sub-centres distributed around the central city, Rome appears to be mostly scattered around the historical city with fragmented urban fabric and heterogeneous economic functions, Athens is denser, with polarized economic spaces and social segregation. Understanding how place-specific factors influence processes of settlement dispersion in Mediterranean contexts may inform policies of urban containment and land-use management.
Protein Sub-Nuclear Localization Based on Effective Fusion Representations and Dimension Reduction Algorithm LDA
Authors: Wang Shunfang , Liu Shuhui
Published: December 2015

An effective representation of a protein sequence plays a crucial role in protein sub-nuclear localization. The existing representations, such as dipeptide composition (DipC), pseudo-amino acid composition (PseAAC) and position specific scoring matrix (PSSM), are insufficient to represent protein sequence due to their single perspectives. Thus, this paper proposes two fusion feature representations of DipPSSM and PseAAPSSM to integrate PSSM with DipC and PseAAC, respectively. When constructing each fusion representation, we introduce the balance factors to value the importance of its components. The optimal values of the balance factors are sought by genetic algorithm. Due to the high dimensionality of the proposed representations, linear discriminant analysis (LDA) is used to find its important low dimensional structure, which is essential for classification and location prediction. The numerical experiments on two public datasets with KNN classifier and cross-validation tests showed that in terms of the common indexes of sensitivity, specificity, accuracy and MCC, the proposed fusing representations outperform the traditional representations in protein sub-nuclear localization, and the representation treated by LDA outperforms the untreated one.

Published: December 2015

Lockin thermography is a well-suited method for the characterization of structures made of both metal and fiber reinforced plastic. In most cases, only phase images are analyzed, although the amplitude images might contain useful information as well. Thus, systematic studies of lockin thermography are presented, assessing amplitude and phase images for the detection and quantification of defects in isotropic (steel) and anisotropic (carbon fiber reinforced plastic) materials. Characterized defects are flat bottom holes with different diameters and various remaining wall thicknesses as well as crossed notches at different depths. The excitation frequency was varied while keeping the number of analyzed excitation periods nearly constant for each material. The data analysis was focused on the detectability of the defects both in the amplitude and phase images, including the determination of the signal-to-noise ratio and of the spatial resolution. As a result, the limits of defect detectability and spatial resolution are given for each material.

Published: December 2015

With the rapid development of WLAN technology, wireless device-free passive human detection becomes a newly-developing technique and holds more potential to worldwide and ubiquitous smart applications. Recently, indoor fine-grained device-free passive human motion detection based on the PHY layer information is rapidly developed. Previous wireless device-free passive human detection systems either rely on deploying specialized systems with dense transmitter-receiver links or elaborate off-line training process, which blocks rapid deployment and weakens system robustness. In the paper, we explore to research a novel fine-grained real-time calibration-free device-free passive human motion via physical layer information, which is independent of indoor scenarios and needs no prior-calibration and normal profile. We investigate sensitivities of amplitude and phase to human motion, and discover that phase feature is more sensitive to human motion, especially to slow human motion. Aiming at lightweight and robust device-free passive human motion detection, we develop two novel and practical schemes: short-term averaged variance ratio (SVR) and long-term averaged variance ratio (LVR). We realize system design with commercial WiFi devices and evaluate it in typical multipath-rich indoor scenarios. As demonstrated in the experiments, our approach can achieve a high detection rate and low false positive rate.
A Simulation Environment for Benchmarking Sensor Fusion-Based Pose Estimators
Authors: Ligorio Gabriele , Sabatini Angelo
Published: December 2015

In-depth analysis and performance evaluation of sensor fusion-based estimators may be critical when performed using real-world sensor data. For this reason, simulation is widely recognized as one of the most powerful tools for algorithm benchmarking. In this paper, we present a simulation framework suitable for assessing the performance of sensor fusion-based pose estimators. The systems used for implementing the framework were magnetic/inertial measurement units (MIMUs) and a camera, although the addition of further sensing modalities is straightforward. Typical nuisance factors were also included for each sensor. The proposed simulation environment was validated using real-life sensor data employed for motion tracking. The higher mismatch between real and simulated sensors was about 5% of the measured quantity (for the camera simulation), whereas a lower correlation was found for an axis of the gyroscope (0.90). In addition, a real benchmarking example of an extended Kalman filter for pose estimation from MIMU and camera data is presented.

The Problem of Sprinkler Reliability
Authors: Šakėnaitė Jurgita
Published: December 2015

Sprinkler systems allow a considerable reduction of fire risk in buildings. Unfortunately, sprinklers are not fail-safe technical systems. Relatively high rates of sprinkler failures evoke the problem of reliability. A solution to this problem is considered from several viewpoints. The diversity of sprinklers' failure modes is the first challenge for estimating reliability (failure probability). It is found that the use of the available data for estimation is problematic. The second challenge is that the published data is insufficiently described to allow a verification of its relevance to the specific case of failure probability estimation. It is suggested to apply the published data with partial relevance to Bayesian inference about failure probabilities. The data is used for developing prior distributions of the unknown values of the probabilities. Bayesian inference is carried out on the basis of binomial distribution used to model the operation of sprinklers on demand basis. A problem of aging and a possible increase in failure probability in the course of sprinkler service is shortly discussed.
