Label-free detection of double-stranded DNA molecules with polyelectrolyte-modified capacitive field-effect sensors
Authors: Bronder Thomas S. , Poghossian Arshak , Keusgen Michael , Schöning Michael J.
Published: April 2017

In this study, polyelectrolyte-modified field-effect-based electrolyte-insulator-semiconductor (EIS) devices have been
used for the label-free electrical detection of double-stranded deoxyribonucleic acid (dsDNA) molecules. The sensor-chip
functionalization with a positively charged polyelectrolyte layer provides the possibility of direct adsorptive binding of
negatively charged target DNA oligonucleotides onto the SiO2-chip surface. EIS sensors can be utilized as a tool
to detect surface-charge changes; the electrostatic adsorption of oligonucleotides onto the polyelectrolyte layer leads to
a measureable surface-potential change. Signals of 39 mV have been recorded after the incubation with the
oligonucleotide solution. Besides the electrochemical experiments, the successful adsorption of dsDNA onto the
polyelectrolyte layer has been verified via fluorescence microscopy. The presented results demonstrate that the signal
recording of EIS chips, which are modified with a polyelectrolyte layer, can be used as a favorable approach for a fast,
cheap and simple detection method for dsDNA.
Using prosodic cues to identify dialogue acts: methodological challenge
Authors: Sikveland Rein Ove , Zeitlyn David
Published: April 2017

This paper addresses the role of prosodic and phonetic features in talk, focussing on how to identify competitive overlaps in conversations. It has previously been claimed that turn competition may be distinguishable from non-competitive overlaps, based on phonetic/prosodic features alone. We test this hypothesis on recordings from a UK-based call center, combining a conversation analytic approach with quantitative methods using a coding scheme. Our long-term aim is to develop large-scale methods operationalizing what we know about conversational sequence and social actions into speech technological applications.

Our findings show that, although there is a tendency for competitive overlaps to be more prominent in terms of loudness and pitch features than non-competitive overlaps, this difference is not sufficient to reliably identify turn competitions from the speech signal itself. We discuss the findings in relation to observations made in individual examples, and conclude by highlighting some of the methodological challenges of applying findings from the linguistic and conversation analytic literature to speech technologies.
Embodiment in Moroccan Arabic storytelling: language, stance and discourse analysis
Authors: Soulaimani Dris
Published: April 2017

This article examines an oral story that displays how embodiment is crucial for understanding language in interaction. It demonstrates how stance, which refers to the way speakers or hearers evaluate the topic of conversation, is an embodied activity. Drawing on theories of discourse analysis, this study examines natural data collected in Morocco and argues that storytelling is a social and interactive practice. A shopkeeper recounts an unusual dining event, which started with commensality and ended with a physical dispute. The storyteller tells his story, enacts its events, and displays stance through intricate forms of embodiment, including contrasts and different ways of producing and copying gestures. Analysis shows that telling a story, beyond a matter of verbal narrative, is performed through embodied enactments to allow for achieving co-participation and alignment. The data also reveal a unique way of intensifying storytelling through both verbal and embodied repetition of selected story events.

Das Wie entscheidet: Haushaltsüberschüsse sinnvoll verwenden
Authors: Schmidt Christoph M. , Schmidt Torsten
Published: April 2017

Die aktuell erzielten Überschüsse in den öffentlichen Haushalten legen die Schlussfolgerung nahe, dass in den kommenden Jahren erhebliche Spielräume für deren Verwendung bestehen. Während im herannahenden Wahlkampf die Rufe nach verschiedenen Varianten von Steuerentlastungen immer lauter werden, verstärken andere Stimmen ihre Forderung nach höheren staatlichen Investitionen. Bei solchen Plänen für die Verwendung der Überschüsse ist jedoch Vorsicht geboten, da es sich aus mehreren Gründen weitgehend um ein flüchtiges Phänomen handeln dürfte. Oberste Priorität sollte daher die Rückführung der Schuldenstandsquote haben, gefolgt von effizienzsteigernden Reformen des Steuersystems. Staatliche Investitionen sollten hingegen der Abwägung von Kosten und Nutzen folgend prioritär durch eine Verschiebung innerhalb der Haushalte bewältigt werden.

Lockie, RG, Dawes, JJ, Kornhauser, CL, and Holmes, RJ. Cross-sectional and retrospective cohort analysis of the effects of age on flexibility, strength endurance, lower-body power, and aerobic fitness in law enforcement officers. J Strength Cond Res 33(2): 451–458, 2019—There can be a great age range in cohorts of law enforcement officers. As the tasks required of officers generally do not change with advancing age, it is important to understand how physical performance in tests that assess job-specific characteristics may be altered. Retrospective analysis of performance test data of 383 officers (362 men and 21 women) was conducted. The tests included the following: sit-and-reach to determine hamstring and lower back flexibility; maximal push-up and sit-up repetitions in 60 seconds to measure muscle endurance; vertical jump (VJ) to assess lower-body power; and 2.4-km run to ascertain aerobic capacity. Data were stratified by age into 20–29, 30–39, 40–49, and 50–59 year groups, and analyzed by sex. A 1-way analysis of variance with the Bonferroni post hoc test was used to calculate the differences between the groups. Considering the male subjects, the 40–49 and 50–59 year groups performed poorer in the VJ, sit-up test, and 2.4-km run compared with the 20–29 year group (p ≤ 0.001–0.045). For the female subjects, the 20–29 year group was superior to the 30–39 (p = 0.013) and 40–49 (p = 0.025) year groups in the push-up test. To ensure that an older officer can successfully complete occupation-specific tasks, lower-body power, abdominal strength, and aerobic training should be completed. Female officers should also attempt to maintain relative upper-body strength. Practitioners must attempt to design training programs that fit within the context of the occupational demands, and potentially using a nontraditional training design as law enforcement officers may not have the time to follow a traditional periodization model.
A Review of Player Monitoring Approaches in Basketball: Current Trends and Future Directions

Fox, JL, Scanlan, AT, and Stanton, R. A review of player monitoring approaches in basketball: current trends and future directions. J Strength Cond Res 31(7): 2021–2029, 2017—Effective monitoring of players in team sports such as basketball requires an understanding of the external demands and internal responses, as they relate to training phases and competition. Monitoring of external demands and internal responses allows coaching staff to determine the dose-response associated with the imposed training load (TL), and subsequently, if players are adequately prepared for competition. This review discusses measures reported in the literature for monitoring the external demands and internal responses of basketball players during training and competition. The external demands of training and competition were primarily monitored using time-motion analysis, with limited use of microtechnology being reported. Internal responses during training were typically measured using hematological markers, heart rate, various TL models, and perceptual responses such as rating of perceived exertion (RPE). Heart rate was the most commonly reported indicator of internal responses during competition with limited reporting of hematological markers or RPE. These findings show a large discrepancy between the reporting of external and internal measures and training and competition demands. Microsensors, however, may be a practical and convenient method of player monitoring in basketball to overcome the limitations associated with current approaches while allowing for external demands and internal responses to be recorded simultaneously. The triaxial accelerometers of microsensors seem well suited for basketball and warrant validation to definitively determine their place in the monitoring of basketball players. Coaching staff should make use of this technology by tracking individual player responses across the annual plan and using real-time monitoring to minimize factors such as fatigue and injury risk.

Phibbs, PJ, Jones, B, Roe, G, Read, DB, Darrall-Jones, J, Weakley, J, Rock, A, and Till, K. Organized chaos in late specialization team sports: weekly training loads of elite adolescent rugby union players. J Strength Cond Res 32(5): 1316–1323, 2018—The aim of this study was to quantify the mean weekly training load (TL) of elite adolescent rugby union players participating in multiple teams and examine the differences between playing positions. Twenty elite male adolescent rugby union players (17.4 ± 0.7 years) were recruited from a regional academy and categorized by playing position: forwards (n = 10) and backs (n = 10). Global positioning system and accelerometer microtechnology was used to quantify external TL, and session rating of perceived exertion (sRPE) was used to quantify internal TL during all sessions throughout a 10-week in-season period. A total of 97 complete observations (5 ± 3 weeks per participant) were analyzed, and differences between positions were assessed using Cohen's d effect sizes (ES) and magnitude-based inferences. Mean weekly sRPE was 1,217 ± 364 arbitrary units (AU) (between-subject coefficient of variation [CV] = 30%), with a total distance (TD) of 11,629 ± 3,445 m (CV = 30%), and PlayerLoad (PL) of 1,124 ± 330 AU (CV = 29%). Within-subject CV ranged between 5 and 78% for sRPE, 24 and 82% for TD, and 19 and 84% for PL. Mean TD (13,063 ± 3,933 vs. 10,195 ± 2,242 m) and PL (1,246 ± 345 vs. 1,002 ± 279 AU) were both likely greater for backs compared with forwards (moderate ES); however, differences in sRPE were unclear (small ES). Although mean internal TLs and volumes were low, external TLs were higher than previously reported during preseason and in-season periods in senior professional players. Additionally, the large between-subject and within-subject variation in weekly TL suggests that players participate in a chaotic training system.

Published: April 2017

Cancer-induced bone pain is characterized by moderate to severe ongoing pain that commonly requires the use of opiates. Even when ongoing pain is well controlled, patients can suffer breakthrough pain (BTP), episodic severe pain that “breaks through” the medication. We developed a novel model of cancer-induced BTP using female rats with mammary adenocarcinoma cells sealed within the tibia. We demonstrated previously that rats with bone cancer learn to prefer a context paired with saphenous nerve block to elicit pain relief (i.e., conditioned place preference, CPP), revealing the presence of ongoing pain. Treatment with systemic morphine abolished CPP to saphenous nerve block, demonstrating control of ongoing pain. Here, we show that pairing BTP induced by experimenter-induced movement of the tumor-bearing hindlimb with a context produces conditioned place avoidance (CPA) in rats treated with morphine to control ongoing pain, consistent with clinical observation of BTP. Preventing movement-induced afferent input by saphenous nerve block before, but not after, hindlimb movement blocked movement-induced BTP. Ablation of isolectin B4 (IB4)-binding, but not TRPV1+, sensory afferents eliminated movement-induced BTP, suggesting that input from IB4-binding fibers mediates BTP. Identification of potential molecular targets specific to this population of fibers may allow for the development of peripherally restricted analgesics that control BTP and improve quality of life in patients with skeletal metastases.

SIGNIFICANCE STATEMENTWe present a novel preclinical measure of movement-induced breakthrough pain (BTP) that is observed in the presence of morphine controlling ongoing pain. Blockade of sensory input before movement prevented BTP, whereas nerve block after movement failed to reverse BTP. These observations indicate that blocking peripheral sensory input may prevent BTP and targeting central sites may be required for pain relief once BTP has been initiated. Preventing sensory input from TRPV1-expressing fibers failed to alter movement-induced BTP. In contrast, preventing sensory input from isolectin B4 (IB4)-binding fibers blocked movement-induced BTP. Therefore, examining molecular targets on this population of nociceptive fibers may prove useful for developing an improved strategy for preventing BTP in cancer patients with skeletal metastases.
“I Learned It through the Grapevine…”: Exploring Atypical Ecosystems in Schools as a New Out-of-School Learning Site
Authors: von Albedyll Astrid , Fritsch Aline , Dreesmann Daniel
Published: April 2017

Ecology may be seen as one of the main topics of biological education as it functions at the interface of several other aspects of biology. Although it may easily be conveyed through field trips and hands-on activities, it is taught theoretically most of the time and in traditional ecosystems like forests or lakes. For this study, new teaching material has been developed that demonstrates the exploration of more special or “atypical” ecosystems in biology classes. It combines working in a local vineyard with hands-on elements for school. By exploring a human-made ecosystem, which is different from those traditionally used, students gain content knowledge and get to know scientific methods. In our case study, students’ learning progress, motivation, and enjoyment of learning were measured. The results indicate that teaching at an out-of-school learning site as well as working with hands-on materials not only has a motivational effect but also increases enjoyment of learning. Furthermore, neglected ecosystems like vineyards serve as new and fitting examples for teaching ecological and plant-biological topics. The results indicate a significant learning gain for the participants. Thus, biology curricula should be broadened to include more and local plants and ecosystems.

Published: April 2017

In this inquiry-based lab, students are provided with a case study involving a young boy with a head injury exhibiting various symptoms, as well as simulated blood and urine samples to help diagnose the boy's disease. Throughout the course of the lab, students research, design, and conduct a series of tests culminating in a patient prognosis. All of the materials, which simulate the blood, urine, and testing compounds, are readily available at the grocery store or online. This real-world problem engages the students to think about negative feedback systems, patient symptoms, the hormones associated with blood glucose levels and urine production, as well as the detection techniques employed by physicians to diagnose patients. Diagnostic methods, testing procedures, and the disease itself make this lab extraordinarily relevant to the lives of students, as evidenced by our students’ reactions to the lab.

Revealing the inner workings of organoids
Authors: Dias Cristina , Guillemot François
Published: April 2017

The mechanisms by which human stem cells self‐organise into brain‐like tissues in 3D organoid culture are poorly understood. In this issue of The EMBO Journal, Renner and Lancaster et al demonstrate that in the absence of external stimuli, human cerebral organoids develop large forebrain structures that display specific landmarks of spatial and temporal patterning, including signalling centres producing known morphogens. The generation of cerebral organoids is therefore likely to reflect normal brain development.
Nuclear receptor research in zebrafish
Authors: Schaaf Marcel J M
Published: April 2017

Nuclear receptors (NRs) form a superfamily of transcription factors that can be activated by ligands and are involved in a wide range of physiological processes. NRs are well conserved between vertebrate species. The zebrafish, an increasingly popular animal model system, contains a total of 73 NR genes, and orthologues of almost all human NRs are present. In this review article, an overview is presented of NR research in which the zebrafish has been used as a model. Research is described on the three most studied zebrafish NRs: the estrogen receptors (ERs), retinoic acid receptors (RARs) and peroxisome proliferator-activated receptors (PPARs). The studies on these receptors illustrate the versatility of the zebrafish as a model for ecotoxicological, developmental and biomedical research. Although the use of the zebrafish in NR research is still relatively limited, it is expected that in the next decade the full potential of this animal model will be exploited.

High recruitment and retention rates in randomized controlled trials are essential to ensure validity and broad generalizability. We used quality improvement methods, including run charts and intervention cycles, to achieve and sustain high recruitment and retention rates during the Hospital-To-Home Outcomes randomized controlled trial. This study is examining the effects of a single nurse–led home health care visit after discharge for an acute pediatric hospitalization. A total of 1500 participants were enrolled in the 15-month study period. For study recruitment, we assessed the percentage of patients who enrolled in the study among those randomly selected to approach (goal ≥50%) and the percentage of patients who refused to enroll from those randomly selected to approach (goal ≤30%). For intervention completion, we examined the percentage of patients who completed the home visit intervention among those randomized to receive the intervention (goal ≥95%) were examined. Follow-up rates were tracked as the percentage of patients who completed the 14-day follow-up telephone survey (goal ≥95%). The study goals for 2 of the 4 metrics were met and sustained, with statistically significant improvements over time in 3 metrics. The median enrollment rate increased from 50% to 59%, and the median refusal rate decreased from 37% to 32%. The median intervention completion rate remained unchanged at 88%. The 14-day follow-up completion median rate increased from 94% to 96%. These results indicate that quality improvement methods can be used within the scope of a large research study to achieve and sustain high recruitment and retention rates.

Authors: Alvarez Herrera Javier Giovanni , Pinzón Gómez Linda Paola , Vélez Javier Enrique
Published: April 2017

The application of fertilizers to rice crops constitutes a large percentage of productions costs, which in recent years have increased; therefore, it is necessary to implement alternatives that optimize the application and improve profitability. It was evaluated the effect of different doses and application times of a fertilizer with silicon on a rice crop, Fedearroz 50 variety. The experimental design was completely randomized with a 2 x 5 factorial arrangement. The first factor was dose (20 and 40 kg ha-1) and the second factor was combination of period and application dose (100% preplant, 50% preplant + 50% first fertilization, 100% first fertilization, 50% preplant +50% second fertilization, 100% second fertilization) for a total of 10 treatments that were applied in 2 locations (Ibagué and El Guamo). We found that the preplant fertilizer applications increased the production of root biomass throughout the crop cycle and that the biomass of the stems and leaves had a similar behavior with the two doses of silicon. The tillering in Ibagué presented a value of 520 clusters m-2, 127% higher than in El Guamo, which had a value of 229 clusters m-2, a highly significant difference. Throughout the period, height showed a behavior model double logistic sigmoid; the height of the rice plants was higher in El Guamo. In the two localities, Ibagué and El Guamo, the most appropriate fertilizer dose of silicon was 20 kg ha-1 in the second fertilization.

Commentary on: Solberg and Jensenius (2016) Investigation of 'intersubjectively embodied experience' in a controlled electronic dance music setting
Authors: Greasley Alinka E.

The motion capture study conducted by Solberg and Jensenius 2016 explores how people's movement on a dance floor is shaped by structural features of electronic dance music (EDM), with a particular focus on the breakdown and drop sections of tracks, the former being characterised by a reduction in musical texture and removal of the rhythmic bassline, and the latter when the rhythmic bassline re-enters and a thicker texture is re-established. The research also explored links between how the participants moved to the dance tracks and their experience of pleasure, and examined the extent to which dancing to EDM can be described as intersubjective. Results showed that the quantity of the dancers' movement reduced during the breakdown, and increased at the drop, as predicted. Ratings of enjoyment of the tracks, and qualitative reflections from the participants provided supporting evidence that the desire to dance increased at the moment of the drop, and that this was influenced by the movement of other people in the setting. In this commentary, I provide an overview of the authors' main arguments and critically evaluate the method and findings with suggestions for future studies.
Commentary on Mari Romarheim Haugen: Investigating Periodic Body Motions as a Tacit Reference Structure in Norwegian Telespringar Performance
Authors: Swijghuisen Reigersberg Muriel
Published: April 2017

This study investigates periodic body motion (foot-tapping and vertical hip motions) as a reference structure in a specific style of traditional Norwegian dance music called telespringar. The intimate relationship between music and motion is often highlighted in rhythm studies of telespringar, so this study encompasses both sound and motion analyses. It is based on a motion capture study of three telespringar performers, examining the foot-stamping of one fiddler and vertical hip motions of two dancers. The results indicate that rather than being primarily derived from the sound itself, the underlying rhythmic structures in telespringar depend upon a shared and embodied knowledge of the underlying asymmetrical reference structure that is implicit in the production and perception of telespringar. I explore here how the methodology used by the author might be further justified and explored. I will also propose ways in which the article could be made more accessible to researchers who question the universality of research outcomes arrived at using laboratory-based experimental settings.

Взгляды Карла Маркса как частичное и неполное отражение системы Давида Рикардо
Authors: Петухов Валерий Александрович
Published: April 2017

Показано что теория Маркса по существу является весьма неполным отражением системы Уэста–Рикардо, так как у Маркса отсутствует анализ понижения нормы прибыли, которое происходит вследствие действия принципа убывающей доходности. Также критически показано общее сходство 2 систем, – а именно, положение о нейтральной роли постоянного капитала при образовании прибыли. Со статьей будет полезно ознакомиться специалистам по истории экономической мысли и по современной экономической цикличности.
Экономическая сущность оборотного капитала и классификация источников его финансирования на предприятии
Authors: Шеина Екатерина Георгиевна
Published: April 2017

В статье исследована экономическая сущность, природа и содержание категории «оборотный капитал». Проведен исторический экскурс в изучении данной категории, рассмотрена эволюция взглядов на ее трактовку разными учеными-экономистами - от авторов классической экономической мысли до формулировок ученых-экономистов XXI века, в результате чего предложены уточненные и дополненные определения понятий «оборотные средства» и «оборотный капитал». По итогам проведенного анализа выделяется два подхода в понимании содержания категории «оборотный капитал» - имущественный и платежный. Автором рассматриваются существующие классификационные признаки непосредственно оборотного капитала, в процессе чего выявляется недостаточная изученность и структурированность источников его финансирования. Данный факт обуславливает необходимость разработать и обосновать авторскую классификацию источников финансирования оборотного капитала предприятий для целей его своевременного пополнения.
Desafíos de la globalización económica
Authors: Lascurain Fernández Mauricio
Published: April 2017

Este artículo pretende analizar los elementos principales del proceso actual de globalización económica como lo son la liberalización del comercio y el flujo de inversión extranjera directa y la movilidad de capital. Las consecuencias de estos elementos exigen una serie de críticas y propuestas relacionadas con la forma en la que los gobiernos locales deben enfrentar la globalización y cuál debería ser el papel de las instituciones internacionales como instrumentos que contribuyan a la integración a la economía mundial, sobre todo en el caso de los países menos desarrollados. El propósito de este estudio es determinar empíricamente los efectos positivos y negativos de la globalización económica en las sociedades nacionales, para poder generar mejores políticas públicas que permitan una alternativa a la gobernabilidad global y una rápida adaptación a la integración global.

A PROPRIEDADE COMO FUNDAMENTO ÉTICO-JURÍDICO E ECONÔMICO-POLÍTICO EM LOCKE
Authors: Mariano da Rosa Luiz Carlos
Published: April 2017

Se a lei natural autoriza o exercício da propriedade através do trabalho, a acumulação de riquezas, baseada na invenção do dinheiro, converge para transformar as diferenças físicas, intelectuais e morais em desigualdade de direito na instituição do Estado jurídico. Atribuindo a condição de propriedade ao trabalho a teoria de Locke dissimula a desigualdade através da “igualdade de relações” de indivíduos abstratos em um sistema jurídico-político que encerra uma liberdade proporcional ao status dos indivíduos como agentes econômicos. Ora, se cabe à sociedade política a delimitação das obrigações da lei natural, o que se impõe ao direito de propriedade individual é a restrição do seu exercício à necessidade, tendo em vista as múltiplas formas que pode assumir como mercadoria nas relações de troca, que implicam a força de trabalho como objeto de troca e consumo em uma formação econômico-social que torna o homem uma simples mercadoria.
Da miscigenação ao pluriculturalismo: questões em torno da ideologia pós-racial e a política da diferença no Brasil
Authors: Da Costa Alexandre Emboaba
Published: April 2017

Este artigo desenvolve o conceito da ideologia pós-racial no contexto brasileiro em relação a idealização da miscigenação e a persistente defesa da democracia racial como uma futura possibilidade ameaçada pelos movimentos antirracistas e pelas políticas de reparações para o povo negro brasileiro. O artigo apresenta dois aspectos em relação a ideologia pós-racial como estratégia de poder. Primeiro, examina a existência da defesa continuada da miscigenação e da democracia racial como possibilidade harmoniosa e igualitária num contexto onde a realidade revela a frequente desumanização e racismo contra negros/as, e um persistente fosso sócio-econômico entre afro-descendentes e euro-descendentes. Segundo, o artigo analisa as políticas públicas étnico-raciais e pluriculturais, argumentando que ao mesmo tempo que elas têm aberto possibilidades para transformação das relações étnico-raciais, elas têm também representado uma institucionalização das demandas do movimento negro e um reformismo que limita a reestruturação radical da base política do estado brasileiro, do conteúdo epistemológico das políticas públicas e da participação cidadã. Especificamente, o exemplo das diretrizes para a implementação da Lei nº 10.639/03 é analisado. Concluo que as políticas antirracistas e pluriculturais negras que propendem à descolonização das relações étnico-raciais necessitam o trabalho crítico e contínuo dos movimentos sociais negros, caso contrário, elas se tornarão cooptativas, incorporando a luta negra em políticas e instituições delimitadas, impedindo transformações sociais mais amplas.
