Body-mass management of Australian lightweight rowers prior to and during competition.

PURPOSE Although the body-mass management strategies of athletes in high-participation weight-category sports such as wrestling have been thoroughly investigated, little is known about such practices among lightweight rowers. This study examined the body-mass management practices of lightweight rowers before competition and compared these with current guidelines of the International Federation of Rowing Association (FISA). Quantification of nutrient intake in the 1-2 h between weigh-in and racing was also sought. METHODS Lightweight rowers (N = 100) competing in a national regatta completed a questionnaire that assessed body-mass management practices during the 4 wk before and throughout a regatta plus recovery strategies after weigh-in. Biochemical data were collected immediately after weigh-in to validate questionnaire responses. Responses were categorized according to gender and age category (Senior B or younger than 23 yr old, i.e., U23, Senior A or OPEN, i.e., open age limit) for competition. RESULTS Most athletes (male U23 76.5%, OPEN 92.3%; female U23 84.0%, OPEN 94.1%) decreased their body mass in the weeks before the regatta at rates compliant with FISA guidelines. Gradual dieting, fluid restriction, and increased training load were the most popular methods of body-mass management. Although the importance of recovery after weigh-in was recognized by athletes, nutrient intake and especially sodium (male U23 5.3 +/- 4.9, OPEN 7.7 +/- 5.9; female U23 5.7 +/- 6.8, OPEN 10.2 +/- 5.4 mg x kg(-1)) and fluid intake (male U23 12.1 +/- 7.1, OPEN 13.5 +/- 8.1; female U23 9.4 +/- 7.4, OPEN 14.8 +/- 6.9 mL x kg(-1)) were below current sports nutrition recommendations. CONCLUSION Few rowers were natural lightweights; the majority reduced their body mass in the weeks before a regatta. Nutritional recovery strategies implemented by lightweight rowers after weigh-in were not consistent with current guidelines.
An adaptive approach to information discovery in multi-dimensional wireless sensor networks

Multidimensional WSNs are deployed in complex environments to sense and collect data relating to multiple attributes (multidimensional data). Such networks present unique challenges to data dissemination, data storage and in-network query processing (information discovery). In this paper, we investigate efficient strategies for information discovery in large-scale multidimensional WSNs and propose the Adaptive Multi-Dimensional Multi-Resolution Architecture (A-MDMRA) that efficiently combines “push” and “pull” strategies for information discovery and adapts to variations in the frequencies of events and queries in the network to construct optimal routing structures. We present simulation results showing the optimal routing structure depends on the frequency of events and query occurrence in the network. It also balances push and pull operations in large scale networks enabling significant QoS improvements and energy savings.
Human Capital Versus the Signaling Hypotheses: the Case of Indonesia

Education positively affects a person's income. It can be explained in two ways. Firstly, education directly increases the productivity of a person, which is in accordance with the views of the theory of human capital. The second way is an indirect effect, in which education acts as a sign (signal) of a worker’s unobserved characteristics, as assessed by an employer who is considering hiring the person. This is consistent with the view of the signaling theory. Both views are often debated in literature. This paper examines the returns to education in Indonesia, separating out the credential effects from the pure years of schooling effects. We used survey data from the Indonesian Family Life Survey (IFLS) 2000, 2007, and 2014 to test the difference of the two theories in estimating the returns to education in Indonesia. This study used three models which consisted of the human capital model , the signaling model , and the hybrid model . The human capital model used the number of years of schooling as a variable representing education, the signaling model used dummy variables from the level of education achieved (elementary school, junior high school, senior high school, diploma, university), and the hybrid model combined both measures of the variables. The hybrid model allows for the separation of the impact of human capital based on an additional year of schooling, and the impact of signaling by the accomplishment of a particular certificate. The results of the study provide strong evidence of the presence of the returns to education either through the human capital or the signaling theories. Keywords: education, human capital, signaling, returns to education
Data quality requirements for water bills

Purpose The purpose of this paper is to uncover the customers’ concerns with the information disclosed in water services invoices and to analyse them with reference to the data quality dimensions usually proposed in the literature. In the context of services of general interest invoices are particularly relevant as a vehicle to convey information to all consumers. Design/methodology/approach Based on the principles of quality planning, the research uses a qualitative approach to identify the data quality requirements of water invoices. Customer voices were collected by means of focus groups and their meanings analysed using an affinity diagram. Findings Findings show that plain language efforts and strategies to enhance trust on the service provided need to be further reinforced. Consumers’ requirements together with the regulator recommendations also confirm the data quality dimensions identified in the literature. Practical implications This research highlights that avoiding technical language and making visible the consequences of different consumption levels on the amounts to be paid is essential when designing water invoices. Moreover, it emphasises that there is still room for improvement in the way the economic regulator performs its role in ensuring the provision of sound information. Originality/value This research addresses a literature gap by conducting a study on data quality requirements outside the context of information systems for organisations. The study is original because it looks at water invoices as a “product” that can be designed to meet the needs of their users.
Transvascular and Interstitial Migration of Neutrophils in Rat Mesentery

Objective: The consequential implications of the leukocyte‐endothelial cell adhesion reaction, as well as the subsequent migratory activity of the leukocytes within the interstitium proper, are currently known only in general phenomenological terms. Our objective was to carry out a detailed quantitative analysis of transendothelial and interstitial migration.
The Juridical Coup d'État and the Problem of Authority

This essay is a true working paper, a work-in-progress that raises a set of questions that I am not yet sure how to answer. The questions are not unknown; indeed, they lurk in the shadows of scholarly discourse on the three systems I will examine. They are, however, often ignored in research and commentary on the constitutional law, and they have never been the focus of comparative inquiry. I nonetheless will argue that the answers one gives to them will bear directly on how we should understand the nature, evolution, and political (i.e., normative) legitimacy of legal systems.
Some remarks on a set of information theory features used for on-line signature verification

Recently a new set consisting of six information theory features was proposed for on-line signature verification by Rosso, Ospina and Frery. The proposed features were evaluated on the MCYT-100 on-line signature database resulting in the best performance ever measured on that dataset. In this paper we repeat their measurements and show that their result is erroneous. In addition, we evaluate the performance of the same on-line signature verification system using exactly the same number of state-of-the-art features. State-of-the-art features always outperform the information theory related features, regardless of the classification method used.
Privacy-Preserving SVM Classification on Vertically Partitioned Data without Secure Multi-party Computation

With the development of information science and modern technology, it becomes more important about how to protect privacy information. In this paper, a novel privacy-preserving support vector machine (SVM) classifier is put forward for a vertically partitioned data. The proposed SVM classifier, which is public but does not reveal the privately-held data, has accuracy comparable to that of an ordinary SVM classifier based on the original data. We prove the feasibility of our algorithms by using matrix factorization theory and show the security without using the secure multi-party computation.
The Waste Footprint of French Households in 2020: A Comparison of Scenarios of Consumption Growth Using Input‐Output Analysis

This study aims at quantifying and analyzing the waste footprint of French household consumption in 2020 with respect to different scenarios of economic growth. Three models are jointly used: (1) a multiregional unilateral input‐output model extended to waste, to quantify waste generation from economic activities induced by household consumption; (2) a coefficient‐based model dedicated to quantifying postconsumer waste as a function of household consumption; and (3) the New Econometric Model of Evaluation by Sectorial Interdependency and Supply (NEMESIS), a macroeconometric model used to elaborate different scenarios of growth in household consumption in the period 2008–2020. Three scenarios consider changes primarily in terms of household consumption volume, while one scenario additionally considers changes in the composition of consumption according to the past‐30‐year trend. First, this study suggests that if the trend in changes of composition is maintained, it will lead, by 2020, to a “relative” decoupling between French household consumption and waste footprint with respect to dry recyclables, mixed wastes, and organic wastes and to an “absolute” decoupling with respect to mineral wastes. Second, this study provides a mapping of the changes in French household waste footprints from 2008 to 2020 as a function of scenarios, with indications of where these changes would actually occur in the economy (waste from economic activities or postconsumer waste) and geographically (in France or abroad). In particular, for most of the scenarios considered, changes in French household consumption from 2008 to 2020 primarily induce changes in organic and mineral waste generation abroad rather than in France.
Software-based synthesis of maximally permissive liveness enforcing supervisory policies for a class of general Petri nets

A Petri net (PN) N(m0) is live if all of its transitions are potentially fireable from every reachable marking. A PN that is not live can be made live by a liveness enforcing supervisory policy (LESP), which decides the set of transitions that are to be permitted at any given marking, such that the supervised-PN is live. We assume there are uncontrollable transitions that cannot be prevented by the LESP. An LESP is said to be maximally permissive, if the fact that it prevents the firing of a transition at a given marking, is sufficient to conclude that all other LESPs would prevent the firing of the same transition at the marking. If there is an LESP for a PN, there is a unique maximally permissive LESP. This paper is about the synthesis of the maximally permissive LESP for a class of PN models with the help of software tools. The paper concludes with a description of ongoing software development activities.
Choice of governance structure and earnings quality

Purpose - The purpose of this paper is to examine the effectiveness of voluntary governance mechanisms in Australia. Design/methodology/approach - This study identifies similar choices of corporate governance by Australian firms and tests the effectiveness of the choices made based on the earnings quality of reported firms. Cluster analysis is conducted using governance best practice variables, firm size and an earnings quality variable. Findings - This paper’s results support the voluntary governance approach for smaller firms, but suggest that mandatory governance requirements could be beneficial for larger firms. Evidence suggests that a benefit accrues for larger firms with the adoption of governance best practice. Cluster analysis indicates that larger firms tend to exhibit higher levels of adoption of governance best practice than smaller firms. Originality/value - This paper adds to the literature by providing important information regarding the suitability of adoption of voluntary governance mechanisms in Australia.
Simian Immunodeficiency Virus Utilizes Human and Sooty Mangabey but Not Rhesus Macaque STRL33 for Efficient Entry

ABSTRACT It has been established that many simian immunodeficiency virus (SIV) isolates utilize the orphan receptors GPR15 and STRL33 about as efficiently as the chemokine receptor CCR5 for entry into target cells. Most studies were performed, however, with coreceptors of human origin. We found that SIV from captive rhesus macaques (SIVmac) can utilize both human and simian CCR5 and GPR15 with comparable efficiencies. Strikingly, however, only human STRL33 (huSTRL33), not rhesus macaque STRL33 (rhSTRL33), functioned efficiently as an entry cofactor for a variety of isolates of SIVmac and SIV from sooty mangabeys. A single amino acid substitution of S30R in huSTRL33 impaired coreceptor activity, and the reverse change in rhSTRL33 greatly increased coreceptor activity. In comparison, species-specific sequence variations in N-terminal tyrosines in STRL33 had only moderate effects on SIV entry. These results show that a serine residue located just outside of the cellular membrane in the N terminus of STRL33 is critical for SIV coreceptor function. Interestingly, STRL33 derived from sooty mangabeys, a natural host of SIV, also contained a serine at the corresponding position and was used efficiently as an entry cofactor. These results suggest that STRL33 is not a relevant coreceptor in the SIV/macaque model but may play a role in SIV replication and transmission in naturally infected sooty mangabeys.
Large retinal ganglion cells that form independent, regular mosaics in the bufonoid frogs Bufo marinus and Litoria moorei

Population-based methods were used to study labeled retinal ganglion cells from the cane toad Bufo marinus and the treefrog Litoria moorei, two visually competent bufonoid neobatrachians with contrasting habitats. In both, cells with large somata and thick dendrites formed distinct types with independent mosaics. The αa, αab, and αc mosaics of Bufo in all major respects resembled those of ranids, studied previously, and could be provisionally matched to the same functional classes. As in other frogs, some αa cells were displaced and many α-cells of all types were asymmetric, but within each type all variants belonged to one mosaic. Nearest-neighbor analyses and spatial correlograms confirmed that all three mosaics were regular and independent. In Litoria, monostratified αa cells were not found. Instead, two bistratified types were present, distinguished individually by soma size and dendritic caliber and collectively by membership of independent mosaics: the larger (∼0.8% of all ganglion cells) was termed α1ab and the smaller (∼2.2%) α2ab. An αc cell type was also present, although too inconstantly labeled for mosaic analysis. Nearest-neighbor analyses and spatial correlograms confirmed that the two αab mosaics were regular and independent. Densities, proportions, soma sizes, and mosaic statistics are tabulated for each species. The emergence of a consensus pattern of α-cell types in fishes and frogs, from which this treefrog partly diverges, offers new possibilities for studying correlations between function, phylogeny, ecology, and neuronal form.
Analytical Modeling of Electromigration Failure for VLSI Interconnect Tree Considering Temperature and Segment Length Effects

Electromigration (EM) is a major concern for very large-scale integration (VLSI) interconnect reliability, particularly for interconnect trees with multibranch metal wires representing continuously connected metal (Cu) lines terminated at diffusion barriers. For EM modeling and assessment, one important problem is to perform fast EM time to failure analysis for practical VLSI chips. Compact modeling for EM effects for the interconnect tree has been studied recently to better EM signoff analysis. But the existing method cannot consider wires stressed under time-varying temperature, which is very typical for practical chip working conditions. In this paper, we develop the exact analytic model for the stress evolution of interconnect trees under different current density and varying segment length from the first principle. Due to the difficulty in obtaining the exact analytical solution, we focus on three-terminal wire in this paper. The stress evolution is modeled by two Korhonen’s equations coupled through boundary conditions which are solved with the Laplace transformation technique. The new analytical EM model is further extended to consider the time-varying temperature stressing condition and initial non-zero residual stress. The proposed method is compared with the finite-element method (FEM) tool COMSOL, the recently proposed eigenfunction-based method, and the published EM simulator XSim. The comparison shows that the analytical solution agrees well with the results from the FEM numerical analysis. It uses much fewer terms compared to the eigenfunction method for the same accuracy. It also agrees very well with XSim, which is consistent with the previously reported measured results.
Impuesto a los ingresos brutos: "Ave fénix" de la estructura tributaria subnacional

The tax structure includes two aspects: the composition of the public resources and the structure of the taxes in particular. In this paper both questions are studied for the own revenues of the Buenos Aires province. The composition has experienced a notable change throughout the time. Gross receipts taxes replaced the other provincial taxes, especially the property tax. The tax has had important changes along the time and exhibits nowadays a complex structure of tax-rates that is studied theoretical and empirically
An Analysis of Trade Between India and Brazil

I N order to see whether the government of a country encourages or discourages imports of particular commodities relative to others, one needs simply look at the nominal tariff structure and the quota system of that country. The quotas, with reasonable approximations, can be translated in terms of the implicit protection rates. The quotas, even when converted to implicit tariff rates and the nominal tariff structure, however, do not always reflect the effective rate of protection provided to the domestic industry. The effective rate of protection, to be defined precisely and rigorously in the succeeding paragraphs, indicates the rate of tariff on the given final commodity net of the tariffs on the inputs of that commodity. The relevant concept that affects (primarily) the domestic producer is the "effective tariff" rather than the nominal tariff. The concept that is (directly) relevant to the domestic consumer, on the other hand, is the nominal tariff. In the development of international trade both the producers as well as the consumers are partners.
Borna Disease Virus Glycoprotein Is Required for Viral Dissemination in Neurons

ABSTRACT Borna disease virus (BDV) is a nonsegmented negative-strand RNA virus with a tropism for neurons. Infection with BDV causes neurological diseases in a wide variety of animal species. Although it is known that the virus spreads from neuron to neuron, assembled viral particles have never been visualized in the brains of infected animals. This has led to the hypothesis that BDV spreads as nonenveloped ribonucleoproteins (RNP) rather than as enveloped viral particles. We assessed whether the viral envelope glycoprotein (GP) is required for neuronal dissemination of BDV by using primary cultures of rat hippocampal neurons. We show that upon in vitro infection, BDV replicated and spread efficiently in this system. Despite rapid virus dissemination, very few infectious viral particles were detectable in the culture. However, neutralizing antibodies directed against BDV-GP inhibited BDV spread. In addition, interference with BDV-GP processing by inhibiting furin-mediated cleavage of the glycoprotein blocked virus spread. Finally, antisense treatment with peptide nucleic acids directed against BDV-GP mRNA inhibited BDV dissemination, marking BDV-GP as an attractive target for antiviral therapy against BDV. Together, our results demonstrate that the expression and correct processing of BDV-GP are necessary for BDV dissemination in primary cultures of rat hippocampal neurons, arguing against the hypothesis that the virus spreads from neuron to neuron in the form of nonenveloped RNP.
The crystal structure of the third signal-recognition particle GTPase FlhF reveals a homodimer with bound GTP

Flagella are well characterized as the organelles of locomotion and allow bacteria to react to environmental changes. The assembly of flagella is a multistep process and relies on a complex type III export machinery located in the cytoplasmic membrane. The FlhF protein is essential for the placement and assembly of polar flagella and has been classified as a signal-recognition particle (SRP)-type GTPase. SRP GTPases appeared early in evolution and form a unique subfamily within the guanine nucleotide binding proteins with only three members: the signal sequence-binding protein SRP54, the SRP receptor FtsY, and FlhF. We report the crystal structures of FlhF from Bacillus subtilis in complex with GTP and GMPPNP. FlhF shares SRP GTPase-specific features such as the presence of an N-terminal α-helical domain and the I-box insertion. It forms a symmetric homodimer sequestering a composite active site that contains two head-to-tail arranged nucleotides similar to the heterodimeric SRP-targeting complex. However, significant differences to the GTPases of SRP and the SRP receptor include the formation of a stable homodimer with GTP as well as severe modifications and even the absence of motifs involved in regulation of the other two SRP GTPases. Our results provide insights into SRP GTPases and their roles in two fundamentally different protein-targeting routes that both rely on efficient protein delivery to a secretion channel.
