Evaluation of the exercise workload of broadcast calisthenics for children and adolescents aged 11–17 years

Abstract The aim of this study was to examine the exercise workload of the 3rd Series of National Broadcast Calisthenics for Elementary and Middle School Students. Altogether, 120 students aged 11–17 years were randomly selected from elementary and middle schools to participate in the study. Each participant performed a cycle ergometer test to obtain maximum oxygen uptake ([Vdot]O2max) and maximum heart rate values. In the laboratory, oxygen uptake ([Vdot]O2), metabolic equivalents (METs), and heart rate were recorded continuously throughout a calisthenics session performed by the participants. Ratings of perceived exertion (RPE) were also recorded. Throughout the calisthenics session, mean percentage of [Vdot]O2 reserve varied from 30.7% to 41.2%, mean percentage of heart rate reserve from 39.0% to 56.9%, and mean RPE from 9.0 to 10.4. The mean energy cost during most of the segments across the four routines of calisthenics was significantly higher (P < 0.05) than 3.0 METs. In conclusion, the exercise workload of the 3rd Series of National Broadcast Calisthenics for Elementary and Middle School Students session varied from low to moderate. As part of a school-based physical activity intervention project, calisthenics would help to promote an active lifestyle and health in children and adolescents.
Co-training for Predicting Emotions with Spoken Dialogue Data

Natural Language Processing applications often require large amounts of annotated training data, which are expensive to obtain. In this paper we investigate the applicability of Co-training to train classifiers that predict emotions in spoken dialogues. In order to do so, we have first applied the wrapper approach with Forward Selection and Naive Bayes, to reduce the dimensionality of our feature set. Our results show that Co-training can be highly effective when a good set of features are chosen.
Preparticipation injury complaint is a risk factor for injury: a prospective study of the Moscow 2013 IAAF Championships

Objectives To determine the health status of athletes before the start of an international athletics championship and to determine whether preparticipation risk factors predicted in-championship injuries. Methods At the beginning of the 2013 International Association of Athletics Federations (IAAF) World Championships, all registered athletes (n=1784) were invited to complete a preparticipation health questionnaire (PHQ) on health status during the month preceding the championships. New injuries that occurred at the championships were prospectively recorded. Results The PHQ was completed by 698 (39%) athletes; 204 (29.2%) reported an injury complaint during the month before the championships. The most common mode of onset of preparticipation injury complaints was gradual (43.6%). Forty-nine athletes in the study reported at least one injury during the championships. Athletes who reported a preparticipation injury complaint were at twofold increased risk for an in-championship injury (OR=2.09; 95% CI 1.16 to 3.77); p=0.014). Those who reported a preparticipation gradual-onset injury complaint were at an almost fourfold increased risk for an in-championship time-loss injury (OR=3.92; 95% CI 1.69 to 9.08); p=0.001). Importantly, the preparticipation injury complaint severity score was associated with the risk of sustaining an in-championship injury (OR=1.14; 95% CI 1.06 to 1.22); p=0.001). Summary and conclusions About one-third of the athletes participating in the study reported an injury complaint during the month before the championships, which represented a risk factor for sustaining an injury during the championship. This study emphasises the importance of the PHQ as a screening tool to identify athletes at risk of injuries before international championships.
Change Management and ERP Implementation Success

Enterprise Resource Planning (ERP) systems have become an integral part of the technology infrastructure of large organizations. However, its implementation has been troublesome partly due to end-user resistance arising out of an inadequate understanding of system functionalities and related processes and fear of disruption to existing work routines. To counter this, ERP implementation teams execute user-centric change management strategies such as the establishment of an ERP help-desk, user involvement in system implementation, end-user training, and the deployment of power-users. This study analyses the impact of these change management strategies on implementation success. Analysis of empirical data indicates that an ERP help-desk and the deployment of power users influence implementation success, whereas user involvement in system design and user training has no significant impact. The study contributes to a better understanding of change management as it relates to the end-user and would aid organizations in prioritizing their strategies.
The Pricing Policy of Banks for Exchange-Traded Leverage Certificates: Interday and Intraday Effects

This paper analyzes the pricing policy of banks for retail exchange-traded leverage certificates. Based on a unique trade data set, we analyze the order flow induced by the investors and compare traded prices with corresponding theoretical fair product values. Our major results are: (i) Intraday effect: Traded leverage certificates are overpriced but the overpricing strongly depends on the time of day the trade is made. At the end of the underlying’s daily trading hours, issuers increase the prices. (ii) Interday effect: The overpricing decreases over the certificate’s lifetime. (iii) The intraday (interday) effect is more pronounced the more (less) likely a premature knock-out of the certificate is. (iv) Both effects are consistent with the investors’ order flow and the gap risk faced by issuers. Banks try to exploit systematic trading patterns of investors to increase their profits.
Evaluation of arsenic trioxide by the pediatric preclinical testing program with a focus on Ewing sarcoma

Arsenic trioxide was tested against the PPTP in vitro panel (1.0 nM to 10 µM) and against the PPTP Ewing sarcoma in vivo panel administered intraperitoneally at a dose of 2.5 mg/kg daily × 5 per week for a planned treatment duration of 3 weeks. Arsenic trioxide showed a median relative IC50 value of 0.9 µM, with Ewing sarcoma cell lines having IC50 values similar to those of the remaining PPTP cell lines. Arsenic trioxide did not induce significant differences in EFS distribution compared to control in any of the Ewing sarcoma xenografts studied, and no objective responses were observed.

Induction of HIF–1α in response to hypoxia is instantaneous

Despite the pivotal role the hypoxia‐inducible factor‐1α (HIF‐1α) plays in physiological and pathological processes, little is known regarding the timeframe and mechanisms involved in its regulation. We determined the onset, accumulation, and degradation of HIF‐1α and a number of redox‐sensitive nuclear factors over a range of pathophysiological oxygen concentrations. Experiments were carried out on nonadherent human HeLaS3 cells placed in tonometers to achieve rapid equilibration between the cell suspension and the various hypoxic/reoxygenation conditions. Exposure to hypoxia for less than 2 min already revealed nuclear HIF‐1α protein induction on Western blots and HIF‐1 DNA binding in EMSAs. One hour after anoxic/hypoxic exposure, nuclear HIF‐1α proteins reached maximal levels, which were maintained for 4 h. Reoxygenation reduced HIF‐1 DNA binding within 2 min, and nuclear HIF‐1α protein levels within 4 to 8 min, down to a level below the detection limit within 32 min. Western blot analysis of the redox sensitive nuclear factors NF‐κB, c‐Fos, c‐Jun, Ref‐1, and thioredoxin showed no alteration in their nuclear levels in response to anoxia/hypoxia, but reoxygenation rapidly caused a transient increase in nuclear NF‐κB and thioredoxin protein levels. The instant initiation of HIF‐1α accumulation shown here limits the hypoxic signaling pathway to below 2 min.
Why are babies getting bigger? Temporal trends in fetal growth and its determinants.

OBJECTIVES To describe temporal trends in fetal "growth" and to examine the roles of sociodemographic, anthropometric, and other determinants. STUDY DESIGN Hospital-based cohort study of 61,437 nonmalformed singleton live births at 22 to 43 weeks' gestational age. Four main measures were examined: (1) birth weight, (2) birth weight-for-gestational-age Z score, (3) small-for-gestational-age (SGA), and (4) large-for-gestational age (LGA), with the latter 3 measures based on a recently developed population-based Canadian reference. Gestational age was based on the last normal menstrual period if confirmed (+/- 1 week) by early ultrasonogram. RESULTS The mean birth weight and Z score increased significantly (P <.0001) among infants > or =37 weeks, with a corresponding reduction in % SGA and a rise in % LGA. No consistent trends were seen among births 34 to 36 or < or =33 weeks. When simultaneous changes in maternal prepregnancy body mass index, gestational weight gain, height, cigarette smoking, and other clinical and sociodemographic factors were controlled by using multiple logistic regression, the temporal trends for term infants were no longer evident. CONCLUSIONS Increases in maternal anthropometry, reduced cigarette smoking, and changes in sociodemographic factors have led to an increase in the weight of infants born at or after term.
An ordered BAC contig map of the equine major histocompatibility complex

A physical map of ordered bacterial artificial chromosome (BAC) clones was constructed to determine the genetic organization of the horse major histocompatibility complex. Human, cattle, pig, mouse, and rat MHC gene sequences were compared to identify highly conserved regions which served as source templates for the design of overgo primers. Thirty-five overgo probes were designed from 24 genes and used for hybridization screening of the equine USDA CHORI 241 BAC library. Two hundred thirty-eight BAC clones were assembled into two contigs spanning the horse MHC region. The first contig contains the MHC class II region and was reduced to a minimum tiling path of nine BAC clones that span approximately 800 kb and contain at least 20 genes. A minimum tiling path of a second contig containing the class III/I region is comprised of 14 BAC clones that span approximately 1.6 Mb and contain at least 34 genes. Fluorescence in situ hybridization (FISH) using representative clones from each of the three regions of the MHC localized the contigs onto ECA20q21 and oriented the regions relative to one another and the centromere. Dual-colored FISH revealed that the class I region is proximal to the centromere, the class II region is distal, and the class III region is located between class I and II. These data indicate that the equine MHC is a single gene-dense region similar in structure and organization to the human MHC and is not disrupted as in ruminants and pigs.
The general principles of scanning electron microscopy

In the transmission electron microscope, as shown in figure 1 (Nixon 1962), the electron gun at the top illuminates the specimen with the beam angle controlled by the condenser lens. The lenses below the specimen are used to magnify the image of the specimen which is viewed on the final screen at many thousand times magnification. If a second electron gun is placed below the fluorescent screen at the bottom of the column and the electron beam is projected upwards through the same lenses this second electron source will be reduced in size by the same amount that the specimen image is magnified. This effect can be observed with both electron guns on at the same time and demonstrates the reversibility of rays through electron lens systems. In this way the resolved point in the specimen image on the fluorescent screen or on the photographic plate is equal to the focused electron probe in the plane of the specimen.
Who innovates out of the crisis

The recent economic crisis has severely reduced the short-term willingness of firms to invest in innovation. But this reduction has not occurred uniformly. A few firms are swimming against the stream by increasing investment during the crisis. This has led to a greater concentration of innovative activities among firms already highly innovative before the crisis. Yet, there remains hope for dynamic entrepreneurs, as we see a small group of fast growing, new firms that also increase innovation investment during the crisis.

New disinfection methods and media are needed to overcome the disadvantages of the current technologies [3]. Nanomaterials are emerging and promising fungicidal, algicidal, and bactericidal media that could be applied for the disinfection of food products. The objective of this article is to review the potential use of nanomaterials for the decontamination of food materials and to define potential research needs for the application of nanomaterials as food decontaminants.
Life-shortening and carcinogenesis in mice irradiated neonatally with X rays.

The characteristics of life-shortening and carcinogenesis were investigated in x-irradiated neonatal B6WFr mice. Animals were irradiated with 24 hr after birth and allowed to complete their normal life span. Mean life span was shortened linearly with doses at a rate of 9.1% per 100 R for females and 9.8% for males. The spectrum of neoplastic diseases was apparently modulated by x irradiation, showing neonatal B6WFr mice to be highly susceptible to the induction of thymic lymphoma, liver tumor, and pituitary tumor. The dose-response relationship for thymice lymphoma could be described by a linear-quadratic model, and linearity could be rejected. Thymic lymphoma developed after a short latent period, resulting in death between 100 and 450 days of age. Liver and pituitary tumors increased with increasing dose up to 400 R and decreased thereafter. The latent period for liver tumor development was apparently shortened with increasing doses. Pituitary tumor developed in excess only in females after a long latent period.
Tensile Stress Effect on Performance of a-IGZO TFTs With Source/Drain Offsets

We report the effect of repeated tensile bending stress on the electrical performance of amorphous-indium–gallium–zinc-oxide (a-IGZO) thin-film transis- tors (TFTs) with source/drain offset. The tensile strain induces the negative transfer shift for the conventional TFTs, but the ON-current (<inline-formula> <tex-math notation="LaTeX">${I}_{ \mathrm{\scriptscriptstyle ON}}$ </tex-math></inline-formula>) increases significantly for the offset TFTs with negligible change in threshold voltage (<inline-formula> <tex-math notation="LaTeX">${V}_{\textsf {TH}}$ </tex-math></inline-formula>). The experimental results can be fitted well with technology computer aided design simulation by the generation of donor-like states in the bending region of the a-IGZO semiconductor. The degraded TFT performance can be completely recovered by thermal annealing at 250 °C for 1 h, confirming the generation of the donor-like metastable defects, oxygen vacancies.
Postoperative outcomes of laparoscopy vesus open nephrectomy in polycystic kidney disease

Background: Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary nephropathy characterized by continuous enlargement of kidney cysts. Kidney volume control is one of the most important treatments of ADPKD. Clinical outcomes of laparoscopic nephrectomy (LN) and traditional open nephrectomy (TN) are still inconclusive. Methods: We searched Embase, Medline, and Cochrane library (up to June 2015) for relevant studies. Meta-analysis was used. The primary outcome was the overall risk of operative complications. Quality assessment was evaluated by the Newcastle-Ottawa scale for cohort studies. Results: Seven retrospective cohort studies were included. Compared with TN, LN was not associated with fewer risk of postoperative complications (OR = 0.53, 95% CI 0.23 to 1.19, P = 0.12). The number needed to treat was 567 according to trial sequential analysis. The risks of arteriovenous fistula thrombosis, wound dehiscence/incision hernia, prolonged ileus, wound hematoma, infections and tear of visceral organ between LN and TN were not significant. Subgroup analysis by hand-assisted laparoscopy (HAL) found the risk of complications decreased significantly in the non-HAL group (OR = 0.36, 95% CI 0.16 to 0.81, P = 0.01) compared with TN, but not in the HAL group (OR = 0.37, 95% CI 0.04 to 3.30, P = 0.37). Conclusions: LN was not associated with decreased risk of complications compared with TN in adult patients with ADPKD. More randomized controlled trials will be needed to demonstrate this in the future.
Hyperspectral Image Restoration Using Low-Rank Tensor Recovery

This paper studies the hyperspectral image (HSI) denoising problem under the assumption that the signal is low in rank. In this paper, a mixture of Gaussian noise and sparse noise is considered. The sparse noise includes stripes, impulse noise, and dead pixels. The denoising task is formulated as a low-rank tensor recovery (LRTR) problem from Gaussian noise and sparse noise. Traditional low-rank tensor decomposition methods are generally NP-hard to compute. Besides, these tensor decomposition based methods are sensitive to sparse noise. In contrast, the proposed LRTR method can preserve the global structure of HSIs and simultaneously remove Gaussian noise and sparse noise.The proposed method is based on a new tensor singular value decomposition and tensor nuclear norm. The NP-hard tensor recovery task is well accomplished by polynomial time algorithms. The convergence of the algorithm and the parameter settings are also described in detail. Preliminary numerical experiments have demonstrated that the proposed method is effective for low-rank tensor recovery from Gaussian noise and sparse noise. Experimental results also show that the proposed LRTR method outperforms other denoising algorithms on real corrupted hyperspectral data.
An evaluation framework of user interaction with metadata surrogates

This paper proposes a framework for the evaluation of user interaction with textual metadata surrogates in the search result interfaces of various types of Information Retrieval (IR) systems. Metadata surrogates are representations of the full-text documents displayed to the user as a list of retrieved results after a search has been performed in an IR system. By examining the metadata surrogates, users can make judgments about the relevance of the full-text document without having to access and evaluate the document itself, thus saving a considerable amount of time and effort. The literature review, however, reveals a lack of frameworks for the evaluation of users' interaction with metadata surrogates. The implications of such a framework would be to inform designers and researchers of IR systems about the main components of users' interaction with metadata surrogates and to facilitate the process of evaluating metadata surrogates in terms of content and presentation.
Issues with Partially Matching Feature Functions in Conditional Exponential Models

Conditional Exponential Models (CEM) are effectively used in several machine learning approaches, e.g., in Conditional Random Fields. Their feature functions are typically either satisfied or not. This paper presents a way to use partially matching feature functions which are satisfied to some degree and corresponding issues while training. Using partially matching feature functions improves the inference accuracy in domains with sparse reference data and avoids overfitting. Unfortunately, the typically used Maximum Likelihood training includes some issues for using partially matching feature functions. In this context three problems (inequality of influence, unlimited weight boundaries and local optima in parameter space) with Improved Iterative Scaling (a popular training algorithm for Conditional Exponential Models) using such feature functions are stated and solved.
Patterns of Entry into Cohabitation and Marriage Among Mainland Puerto Rican Women*

This paper adds to our limited knowledge of racial and ethnic variation in union formation by describing and analyzing the first unions of mainland Puerto Rican women. Retrospective history data show that Puerto Ricans have shared in the post-l970 shift toward cohabitation. Puerto Rican women, however, are much more likely to enter informal first unions than the general population, and have a low propensity to transform informal unions into legal marriages. The paper examines the influence of family background and current activities on union timing and type. The relationship between partner attributes and the choice between formal and informal coupling is also considered.
The informal use of antiretroviral medications for HIV prevention by men who have sex with men in South Florida: initiation, use practices, medications and motivations

Abstract Limited data suggest that some gay and other men who have sex with men are using antiretroviral medications informally, without a prescription, for HIV prevention. This qualitative study examined this phenomenon among gay and other men who have sex with men in South Florida. Participants initiated informal antiretroviral medication use as a means of protecting each other and because of the confidence in knowledge of antiretroviral medications shared by their friends and sex partners. The most commonly used medications included Truvada and Stribild. Motivations for use included condom avoidance, risk reduction, and fear of recent HIV exposure. Participants described positive and negative sentiments related to informal use, including concerns about informal antiretroviral medications offering sufficient protection against HIV, and limited knowledge about pre-exposure prophylaxis (PrEP). Because the antiretroviral medications used for PrEP have the potential to prevent HIV infection, future research must consider the informal antiretroviral medication use and related concerns, including adherence, diversion and viral resistance.
THE ROLE OF RISK ASSESSMENT IN MANAGING RISK

The new landscape of the 21st century, while promising unparalleled advancements and growth, is fraught with a variety of hazards and risks. As multinational companies operate across borderless and timeless dimensions of the international market place, coupled with rapid transportation systems, the risks of introduction and spread of emerging and re-emerging diseases and other risks continue to expand across the globe (Krause, (Ed.) 1998, Fauci, 1998). Recent examples of emerging/re-emerging diseases and pests of livestock and crops include Hong Kong Avian Influenza (H5N1), E. Coli (O157), foot and mouth disease (FMD), bovine spongiform encephalopathy (BSE), classical swine fever (CSF), Nipah virus, West Nile Virus (WNV), New Castle Disease, sorghum ergot, karnal bunt and pfisteria,( Taylor et. al., 2001 ) to name a few. Once introduced into a country or region, the concentration of large agricultural enterprises and intensive production systems and global distribution of foods further hastens the spread of diseases and pests. The US food and agricultural system constitutes the largest positive element in the US international trade balance and involves assets in excess of a trillion dollars. Since it provides almost 20% of the nation’s employment, such threats are of great concern. Most significantly too, recent threats from bioterrorism have added a more urgent dimension to either prevent and/or minimizing the catastrophic consequences that may arise as a result of introduction of such dangerous diseases and pests.
