Sexual health education outcomes within Canada’s elementary health education curricula: A summary and analysis

Abstract:There continues to be much concern about Canadian students’ access to sexual health education within their schools’ health education programs. This concern continues in a largely unique national context—one in which health education curricula vary across all territories and provinces. At the same time, the United Nations Educational, Scientific and Cultural Organization (UNESCO, 2018) has recently published its updated International Technical Guidance on Sexuality Education. These UNESCO guidelines provide key concepts, topics, and technical guidance about sexual health-related topics that are advisable for students in all grades, including for those students in Kindergarten/Primary (K/P) through Grade 6. In this article, we provide a summary and critical analysis of sexual health education outcomes within all of Canada’s elementary health education curricula. This summary and analysis should be of particular relevance to those who share an interest in health education and/or sexual health education, particularly within Canadian and/or other Western schooling contexts.
Success Factors of Village-Owned Enterprises (BUMDes) Performance in Indonesia: An Exploratory Study

The full autonomy given to village governments by the Indonesian government coming with the demand to establish Village-Owned Enterprises (BUMDes) brings both opportunities and challenges. The reason is that not all BUMDes which have been established could perform satisfactorily. In fact, out of 3900 existing BUMDes, only a small percentage showed satisfactory performance. Based on this background, this research aims to investigate key success factors which drive the performance of BUMDes. The research was conducted from November to December 2018. The research subjects were BUMDes Amarta, Srimartani Makmur, and Tirtonirmolo, which are located in the Special Region of Yogyakarta, Indonesia. These three BUMDes were chosen because they serve as a benchmark for how BUMDes in Indonesia should be managed. The research informants were directors and employees of these BUMDes where each BUMDes was represented by one director and one employee. The data were obtained from direct interviews and documentation. The data were analyzed using a qualitative approach, consisting of such steps as data reduction, data display and conclusion drawing. The results indicated that the factors that drive the performance of BUMDes were BUMDes employees’ patriotism and passion, skills, training, level of education, experience, honesty (ethical behavior), having a sense of responsibility, sincerity, seriousness, caring for the environment and society, being resilient, cohesiveness of teamwork, transparent communication between BUMDes managers, never-give-up attitude in trying to achieve the performance targets, religiosity, work satisfaction, visionary (transformational) leadership style, and the presence of incentive mechanisms.
Geometry Analysis and Optimization of PM-Assisted Reluctance Motors

This paper deals with a detailed geometry analysis of the rotor structure for both synchronous reluctance and permanent magnet (PM)-assisted reluctance motor in order to suggest an automatic procedure to design the rotor structure. The shape of flux barriers is selected to achieve both high <inline-formula><tex-math notation="LaTeX">$d$ </tex-math></inline-formula>-axis inductance and low <inline-formula><tex-math notation="LaTeX">$q$</tex-math> </inline-formula>-axis inductance to obtain high output torque and high power factor. Methods to properly design the geometry of the ends of each barrier and PMs are adopted. In order to draw a rotor with proper shape, different modifications are discussed. All details are described to allow any reader to adopt the same procedures. After that, such a procedure is used to rapidly analyze the impact of some geometry changes on the machine performance to give a design guideline. The analyzing process starts from a reluctance motor considering the number of barriers, insulation ratio, split ratio, and slots per pole per phase. Then, the PMs are inset into flux barriers and the effect of PM width on torque, power factor, and flux weakening capability is investigated. At last, the demagnetization limit under overload operations is analyzed.
Principal’s Decision-Making in Bridging the Student Achievement Gap

ABSTRACT This paper explores the student achievement-related decision-making processes of eight school principals in Ontario, Canada. First, we describe Ontario’s public education system with respect to neo-liberalism and student achievement. Next, we review general approaches to reducing the achievement gap as it pertains to matters of race. We then show how these eight Ontario school leaders make decisions to reduce the achievement gap within their respective schools. This decision-making process is influenced by considerations such as economic conditions, learning styles and school-based or individual solutions. While it is acknowledged that principals do not operate in isolation, our study focuses on the high level of responsibility principals are vested with in order to provide leadership for student outcomes, while taking other factors into account within the decision-making process.
Fundamental Studies for the STF-type Power Coupler for ILC

From the view point of mass-production for the power coupler in ILC (International Linear Collider), the fundamental studies for the STF-type power coupler are under progress by the collaboration between KEK and TETD. At present, there are various rinsing procedures for power coupler in the world-wide laboratories. In this R&D, the main topic is to investigate the various rinsing effects in the copper plating and the ceramic through the high power test. In this paper, the first results will be presented.
A current control technique for induction machine drives using integrated pilot current sensors in the low-side switches

A new current regulation algorithm is presented that achieves indirect field-oriented control (IFOC) for three-phase induction motor drives using current feedback information provided by three integrated pilot sensors in the three low-side inverter switches. A new regulator is required for this configuration of pilot sensors because each sensor can measure its phase current during only half-of each fundamental frequency cycle. A technique has been developed to reconstruct the three phase currents during the intervals when they are not measured so that the phase current can be used to achieve field-oriented control of the machine. Experimental results are provided to confirm the attractive performance characteristics of the proposed control technique during both steady-state and transient operation. Key application issues including the impact of errors in the estimated machine parameters are discussed.
Manual curation and reannotation of the genomes of Clostridium difficile 630Δerm and Clostridium difficile 630.

We resequenced the genome of Clostridium difficile 630Δerm (DSM 28645), a model strain commonly used for the generation of insertion mutants. The genome sequence was obtained by a combination of single-molecule real-time (SMRT) and Illumina sequencing technology. Detailed manual curation and comparison to the previously published genomic sequence revealed sequence differences including inverted regions and the presence of plasmid pCD630. Manual curation of our previously deposited genome sequence of the parental strain 630 (DSM 27543) led to an improved genome sequence. In addition, the sequence of the transposon Tn5397 was completely identified. We manually revised the current manual annotation of the initial sequence of strain 630 and modified either gene names, gene product names or assigned EC numbers of 57 % of genes. The number of hypothetical and conserved hypothetical proteins was reduced by 152. This annotation was used as a template to annotate the most recent genome sequences of the strains 630Δerm and 630. Based on the genomic analysis, several new metabolic features of C. difficile are proposed and could be supported by literature and subsequent experiments.
Concurrent file reorganization for record clustering: a performance study

The authors presents performance analysis of a concurrent file reorganization algorithm. They examined the effect of buffer size, degree of reorganization, and write probability of transactions on system throughput. The problem of file reorganization considered involves altering the placement of records on pages on a secondary storage device. This reorganization must be done in-place. The approach is appropriate for a non-in-place reorganization. The motivation for such a physical change is to improve the database system's performance, by minimizing the number of page accesses made in answering a set of queries. It is shown through simulation that the algorithm, when run concurrently with user transactions, provides an acceptable level of overall database system performance. <<ETX>>
3D ultrasound palm vein recognition through the centroid method for biometric purposes

A few years ago, some of the authors proposed an ultrasound technique for achieving 3D palm vein patterns for biometric recognition purposes. That technique was developed with a commercial imaging system using doppler modality. Unfortunately, even if results were promising, the acquisition time was too long for practical applications. More recently, they proposed an effective recognition system that employs an ultrasound research scanner (ULA-OP), a CNC pantograph and a high frequency (12 MHz) commercial probe. The system is able to acquire 3D image of the human palm (38×25×15 mm3) in about 4 seconds. Successively, they developed a procedure to extract palmprint features and validated it with verification and identification experiments on a consistent ad hoc established database. In this work, a new method for extracting palm vein pattern is proposed. The procedure uses as input the same 3D images already exploited for extracting palmprint features, as matter of fact upgrading the recognition system to a multimodal system.
Small Signal Modeling of A High Bandwidth Voltage Regulator Using Coupled Inductors

Today's voltage regulator (VR) for the microprocessor requires a current loop to achieve adaptive voltage positioning (AVP) and phase current sharing. A fundamental limitation, current loop sample hold effect, limits the control bandwidth to be pushed beyond 1/6 of the switching frequency. This paper reveals the limitation of the control bandwidth of a two-phase buck converter using peak current control scheme. The limitation can be overcome by coupling the two output inductors. A new small signal model is proposed to study the sample hold effect in coupled-inductor implementations. The relationship between the coupling coefficient and the sample hold effect is then discussed. Based on these understandings, a strongly coupled two-phase buck converter has double the bandwidth of the non-coupled VR; and this is experimentally verified
Sparse Reactive Power Scheduling by a Penalty Function - Linear Programming Technique

This work presents a linear programming based algorithm to solve reactive power dispatch problems. A mixed set of variables (generated voltages and reactive power injections) and the reactive power model of the fast decoupled load flow algorithm are used to derive linear sensitivities. A suitable criterion is suggested to form a sparse reactive power sensitivity matrix. The sparse sensitivity matrix is in turn modeled as a bipartite graph which is used to define an efficient constraint relaxation strategy to solve linearized reactive power dispatch problems. The penalty function - linear programming technique method is used in a complete reactive power dispatch solution algorithm, the performance of which is discussed by solving a 256-node, 58 control-variable test system.
Temperature investigation of frequency upconversion in Er3+/Yb3+-codoped PLZT electro-optic ceramic

The upconversion fluorescence spectra of Er3+/Yb3+: PLZT excited at 980 nm were measured from 10K to 320K. A model for the dynamics of frequency upconversion process was proposed. Based on this model, the upconversion luminescence intensities were fitted as a function of temperature and the temperature characteristics of upconversion luminescence were discussed.
Using partial least squares (PLS) for digital government research

PLS is a structural equation modeling (SEM) technique similar to covariance-based SEM as implemented in LISREL, EQS, or AMOS. Therefore, PLS can simultaneously test the measurement model (relationships between indicators and their corresponding constructs) and the structural model (relationships between constructs). However, unlike its covariance-based counterpart, PLS allows researchers to working with small samples, too many or too few variables, data from non-normal or unknown distributions, and relatively new theories in which relationships between variables are not well defined. This tutotial shows how to use partial least squares (PLS) and argues that the correct use of this technique could help to incorporate more realistic assumptions and better measurements into digital government research. It does it through a commented example of a digital government research study.
Multi-target tracking in clutter without measurement assignment

This paper presents a new approach for multitarget tracking in a cluttered environment. Optimal all neighbour multi-target tracking (MTT) in clutter enumerates all possible joint measurement-to-target assignments and calculates the a posteriori probabilities of each of these joint assignments, e.g. J(I)PDA and MHT. The numerical complexity of this process is exponential in the number of tracks and the number of measurements involved. Our approach starts with an all-neighbour single-target tracking (STT) filter which provides the a priori probabilities of measurement origin; e.g. IPDA, IMM-PDA, ITS. These probabilities are used to modify the clutter density at the location of the selected measurements. In effect, the STT filter is transformed into a MTT filter with a numerical complexity which is linear in the number of tracks and the number of measurements. Measurement features, such as amplitude, can also be incorporated. Simulations are used to verify the approach when tracking crossing targets in an environment of heavy and non-uniform clutter.
Coupled Electromagnetic and Thermal Analysis of an Axial Flux PM Machine

The rotor discs in axial flux permanent magnet (PM) machines have similar properties as a radial fan, and therefore, the convective cooling may have a significant influence on the thermal design of these machines. To research the impact of convective cooling on the thermal properties of axial flux PM machines, a coupled electromagnetic and thermal model is introduced in this paper. This technique models a segment of the stator and the rotor only and links them together by analytical equations of the convective heat transfer at different boundaries of the machine model. This results in an accurate and time efficient multiphysics model. The coupled electromagnetic and thermal modeling technique is validated with measurements on a 4 kW axial flux PM machine having the yokeless and segmented armature topology.
Response to Letter.

Numerical modelling enables a comprehensive understanding not only of the Earth’s system today, but also of the past. To date, a significant amount of time and effort has been devoted to paleoclimate modeling and analysis, which involves the latest and most advanced Paleoclimate Modelling Intercomparison Project phase 4 (PMIP4). The definition of seasonality, which is influenced by slow variations in the Earth’s orbital parameters, plays a key role in determining the calculated seasonal cycle of the climate. In contrast to the classical calendar used today, where the lengths of the months and seasons are fixed, 5 the angular calendar calculates the lengths of the months and seasons according to a fixed number of degrees along the Earth’s orbit. When comparing simulation results for different time intervals, it is essential to account for the angular calendar to ensure that the data for comparison is from the same position along the Earth’s orbit. Most models use the classical calendar, which can lead to strong distortions of the monthly and seasonal values, especially for the climate of the past. Here, by analyzing daily outputs from multiple PMIP4 model simulations, we examine calendar effects on surface air temperature and precipitation 10 under mid-Holocene, last interglacial, and pre-industrial climate conditions. We conclude that: (a) The largest cooling bias occurs in boreal autumn when the classical calendar is applied for the mid-Holocene and last interglacial, due to the fact that the vernal equinox is fixed at 21th March. (b) The sign of the temperature anomalies between the Last interglacial and preindustrial in boreal autumn can be reversed after the switch from classical to angular calendar, particularly over the Northern
H-matrix sparsifícation applied to bioelectromagnetic analysis of large scale human models

This work proposes the use of H-matrices with Adaptive Cross Approximation for the solution of very large sparse/dense block linear systems. Such matrices are typically generated by hybrid differential/integral formulations applied to bioelectromagnetic problems which make use of large scale human models. An example of application related to magnetic resonance imaging dosimetry is presented to illustrate the usefulness of the method.
BitFlow: Enabling real‐time cash‐flow evaluations through blockchain

Disbursement registration has always been a cumbersome, opaque, and inefficient process, up to the point that most businesses perform cash‐flow evaluations only on a quarterly basis. We believe that automatic cash‐flow evaluations can actively mitigate these issues. In this paper, we present BitFlow, a blockchain‐based architecture that provides complete cash‐flow transparency and diminishes the probability of undetected frauds through the BitKrone, a non‐volatile cryptocurrency that maps to the Danish Krone (DKK). We show that confidentiality can be effectively achieved on a permissionless blockchain using Zero‐Knowledge proofs, ensuring verifiable transfers and automatic evaluations. Furthermore, we discuss several experiments to evaluate our proposal, in particular, the impact that confidential transactions have on the whole system, in terms of responsiveness and from an economical expenditure perspective.
An interactive method for extracting grammar from programs

The grammar of the language in which some given code is written is essential for developing automated tools for maintenance, reengineering, and program analysis. Frequently grammar is available for a language but not for its variants that are implemented by various vendors and in which the given code may be written. In this work we address the problem of obtaining the grammar from source code, which can then be used for generating tools for the programs. We propose an incremental method for obtaining grammar for a particular language variant, from a set of programs written in the language variant and an approximate grammar (presumably of the standard language) with some user interaction. We also present the design of a tool for implementing this approach and our experience in working with grammars of C, C++ and COBOL. Copyright © 2004 John Wiley & Sons, Ltd.
Electromagnetic Near Fields as a Function of Electrical Size

The near fields of a radiating rectangular plate placed over and normal to an infinite horizontal ground plane have been analyzed as a function of the electrical size of the plate. Both vertical and horizontal currents are taken into account. Two different methods are used to compute the near fields. The variation of the electric field along the normal to the plate is studied in detail as a function of the electrical length L/¿ of the plate. The electric-field magnitude decreases as distance r increases until an oscillatory region is encountered about one wavelength from the plate. Oscillations continue until distance is equal to L2 /4¿, or one-eighth of the usual far-field distance. The location of various minima and maxima can be predicted by a consideration of Fresnel theory. Comparison is made with the near fields of a circular aperture.
Effect of Mechanical Damages and Storage Conditions on Quality of Markies cv. Potatoes for Processing

Aims: Evaluate whether mechanical damage and storage conditions affect the quality of the ‘Markies’ potato for processing. Study Design: The experimental design was the completely randomized, in the scheme of split-plots. The plots were composed of treatments with and without mechanical damage and the subplots were made up by the evaluation times, with 5 replicates, where the experimental unit was composed of 2 tubers. Place and Duration of Study: Tubers of the ‘Markies’ cultivar from the producing region of Perdizes, State of Minas Gerais, were planted in June 2016 and harvested in October 2016. Methodology: The tubers were stored for 2 months at 8°C, and further divided into treatment with damage, in which the tubers were subjected to impact and abrasion; and control treatment, in which the tubers were not damaged. After that, they were stored at 28°C and evaluated for their loss of loss of accumulated fresh mass (FML), total soluble sugar (TSS), reducing sugar (RS), non-reducing sugar (NRS) and color after frying in the periods of 0, 12, 24, 36 and 48 h after being placed at room temperature. Results: The mechanical damage in the tubers increased FML, however, it did not affect the content of TSS, NRS, RS and color after frying. Increases were observed in the content of TSS and NRS after 12 h of evaluation. Grade 2 was assigned to the coloring scale after frying for the tubers regardless of treatment or evaluation period. Conclusion: Mechanical damage increases the FML and the ‘Markies’ cultivar is suitable for the industry of pre-fried potato processing even under the occurrence of mechanical damage and exposure to high temperatures.
Digital Imaging Based Measurement of Diesel Spray Characteristics

This paper presents a direct photographic imaging and image processing system for the analysis and characterization of diesel sprays. A high-resolution CCD camera with a flash light source is used to capture the spray images through an optically accessible, constant volume chamber. A set of macroscopic characteristic parameters of the sprays including tip penetration, near and far field angles, spray tip velocity and average fuel area density are derived from the images. Experimental work was undertaken on a common rail fuel injection rig. The relationships between the spray characteristics and corresponding injection conditions are presented and discussed
Improved Chaotic Particle Swarm Optimization with a Perturbation-Based Chaotic System for a Virtual Quartic Function

In this paper, we discuss the particle swarm optimization method (PSO). In particular, we focus on the CPSO-VQO, a PSO with a perturbation-based chaotic system derived from the steepest descent method for a virtual quartic function having global minima at the lbest and gbest, which selects the updating system of the particle's position from the standard system of the original PSO and the chaotic one on the basis of a threshold distance between two bests. Although the good performance of CPSO-VQO is reported, it is not so easy to select appropriate parameter values of its chaotic system for each problem because the bifurcation structure of the chaotic system depends on the distance of two bests, and, moreover, it is required an appropriate threshold for selecting the updating system. Therefore, we improve the CPSO-VQO by proposing a modified chaotic system having the bifurcation structure irrelevant to the distance of two bests, and a new stochastic selection of the updating system. In addition, we theoretically show the desirable properties of the modified chaotic system and evaluate the improved CPSO-VQOs called CPSO-TSV and CPSO-SSV.
