The Effect of Parenting Styles on Children’s Familiarity with Traffic Signs

The community, and especially the family, affects children’s traffic safety. Parents influence children’s current and future traffic behaviors. Numerous studies have demonstrated a relationship between parenting style and children’s behavioral problems such as antisocial behaviors and delinquency, so the modification of parenting styles could have a positive impact on the interactions between parents and children. In the literature on children’s traffic safety, parental influence has long been recognized as an important aspect of research, but parent-related factors are mostly unknown. In particular, a factor that can affect parents’ attitudes and children’s views of road safety is parenting style. Therefore, this study aims to examine children’s knowledge of traffic signs utilizing a parenting styles’ perspective. The determining role of demographic characteristics in traffic skills is critical and is investigated in this study. In this study, 1011 preschool, first-, second-, and third-grade students were interviewed and information about parenting styles and demographic characteristics were collected from questionnaires completed by parents. Through interviews, children’s familiarity with law enforcement and informative signs was assessed. Results indicated that older children and those with higher socioeconomic status had better skills in this field. The results also showed that parents could improve their children’s understanding of signs by less use of inconsistent discipline and corporal punishments. Parental negligence, contradictory use of corporal punishment, and nonuse of positive behaviors are some factors which are most likely related to children’s knowledge of traffic signs and rules. The findings of this study can guide parents and assist relevant authorities to implement policies to more effectively train young children by developing practical and targeted resources.
Molecular Epidemiology of Theileria annulata in Cattle from Two Districts in Punjab (Pakistan)

Simple Summary Pakistan is a tropical country where climate is favourable for tick growth and hence its incidence of tick-borne diseases is high, affecting the output of the livestock sector. In the present study the infection rate of Theileria annulata, the causative agent of bovine theileriosis, was compared in apparently healthy cattle enrolled from two different regions in Pakistan. Parasite prevalence was found to be higher in Dera Ghazi Khan District than in Lodhran. The infection rate was higher in cattle that were infested with ticks and in those animals that were housed indoors at dairy farms with other animals. This prophylactic detection of parasite will help to design strategies to control tick and tick-borne diseases in study areas. Abstract The present study was designed to report the molecular prevalence of T. annulata in cattle blood samples collected from Punjab in Pakistan. A total of 428 cattle blood samples were collected from Districts Lodhran (n = 218) and Dera Ghazi Khan (n = 210). The prevalence of T. annulata was determined by the amplification of a fragment from its cytochrome b gene and parasite prevalence was significantly higher (p = 0.03) in the blood samples of cattle collected from Dera Ghazi Khan (70/210; 33%) as compared to Lodhran (52/218; 24%). Presence of T. annulata was also confirmed by the amplification of a fragment from their 30 kDa gene. The amplified PCR products of both genes were confirmed by DNA sequencing and these partial DNA sequences were submitted to GenBank. Phylogenetic analysis revealed that amplified partial gene sequences resembled previously reported T. annulata sequences in cattle from India, China, Iran, Tunisia, Turkey and Egypt. The incidence of T. annulata infection was higher in Sahiwal cattle (p = 0.04) than the other enrolled cattle breed from Dera Ghazi Khan. Female cattle from Lodhran (p = 0.02), while males (p = 0.02), animals housed in close compounds (p = 0.04), animals with a tick burden (p = 0.005) and farms with only cattle (p = 0.01) in Dear Ghazi Khan were found to be more susceptible to T. annulata infection. We recommend that large-scale tick and tick-borne disease control strategies be implemented in both districts under investigation, especially in Dera Ghazi Khan.
Ultrasonic Imaging of Carotid Inflammatory Plaque with Superparamagnetic Nanoparticles

Chronic inflammation can stimulate the formation and progression of atherosclerotic plaques and increase the vulnerability of plaques. However, there are few studies on the changes of carotid inflammatory plaques during treatment. Our study attempted to investigate the use of superparamagnetic iron oxide nanoparticle (SPION) ultrasound imaging to detect the expression of vascular cell adhesion molecule-1 (VCAM-1) in patients with carotid plaques and analyze the effects of SPION ultrasound imaging in inflammatory plaque visualization effect. SPION microbubble contrast agents have good imaging effects both in vivo and in vitro. We conjugated the VCAM-1 protein to the microbubbles wrapped in SPIONs to form SPIONs carrying VCAM-1 antibodies. Observe the signal intensity of SPIONs carrying VCAM-1 antibody to arteritis plaque. The results showed that the SPION contrast agent carrying VCAM-1 antibody had higher peak gray-scale video intensity than the other two groups of contrast agents not carrying VCAM-1 antibody. It shows that SPIONs have excellent imaging effects in ultrasound imaging, can evaluate the inflammatory response of arterial plaque lesions, and are of great significance for the study of carotid inflammatory plaque changes.
Numerical Simulation of Sound from Flow over an Airfoil with a Blunt Trailing Edge

The objective of this study was to investigate the sound generated by flow over an airfoil with a blunt trailing edge. Numerical simulations were performed using the Lattice-Boltzmann Method (LBM) with the Very Large-Eddy Simulation (VLES) approach. The distinct advantage of LBM over other Navier-Stokes based computational fluid dynamics (CFD) methods lies in its ease of handling problems with complex geometries. A 3-D simulation over a 45 o asymmetric blunt trailing edge with a freestream Mach number of M1 D 0:09 and Rec D 1:85 10 6 was performed. Comparisons were made with detailed experimental data for validation. A computed shedding frequency of fLBM D 215 Hz was obtained. The measured frequency was fexp D 219 Hz. The discrepancy could be attributed to differences between the experimental and numerical setup. The far-field noise was predicted using both the solid and porous Ffowcs Williams-Hawkings (FWH) surface integral acoustic method. The far-field spectra showed good agreement with experiments up to the grid cut-off frequency.
Highly stable operations of transversecoupled cavity VCSELs with enhanced modulation bandwidth

The highly stable operation of 980 nm transverse coupled cavity vertical cavity surface emitting lasers (VCSELs) with enhanced modulation bandwidth for high-speed optical interconnects is reported. The device operates at 25 Gbit/s from 0 to 60°C with fixed driving conditions. In addition, the stability of driving currents into the VCSEL is explored, exhibiting that the bandwidth enhancement is not sensitive to the current. The ultra-compact inplane coupled cavity VCSEL can boost the modulation speed beyond the relaxation oscillation frequency because of the to photon–photon resonance, which makes it useful in next-generation computing and data centre networking.
Non-zero Mean Alpha Oscillations are Evident in Computational Model and Empirical Data

Oscillations and evoked responses are two main types of neuronal activity recorded non-invasively with EEG/MEG. Although typically studied separately, they might in fact represent the same neuronal process. One possibility to unite them is to demonstrate that neuronal oscillations have non-zero mean which would indicate that stimulus- or task-triggered amplitude modulation of oscillations will unavoidably lead to the generation of evoked responses. We validated this mechanism using computational modelling and analysis of a large EEG data set. With a biophysical model, we indeed demonstrated that the mean of alpha oscillations is non-zero for a wide range of model parameters. In EEG data we detected non-zero mean alpha oscillations in about 96% of the participants. Furthermore, using complementary neuronal-ensemble modelling, we provided an explanation for the previously observed discrepancies between evoked responses and oscillatory amplitude changes after stimulus presentation. Overall, our results provide strong support for the unification of neuronal oscillations and evoked responses.
The two winding ferrite core transformer: An experimental method to obtain a wide frequency range equivalent circuit

An equivalent diagram with localized constants has been created to represent the two winding transformer. The equivalent diagram with localized constants is practically independent of the transformer construction. Only the numeric constants change from one component to another. This circuit can be introduced into converter simulation software, and leads to very realistic forecasts even when working at high frequency. The authors describe, taking a classical transformer as an example, the experimental method which allows all the diagram constants to be determined with impedance measurements outside the component. The features and advantages of this diagram are discussed. <<ETX>>
Supervisory Generalised Predictive Control for electro-fluid systems

A control engineer is required to design a system to meet the specified desired performance with guaranteed reliability and safety. Reliability and safety are particularly important in the field of process control. However, not only in process control but also in other industrial applications, reliability and safety are emphasised as well as the performance of the controller. The goal of a supervisory structure is to establish the health of a system and design an alarm system for the user in the hope of preventing undesirable consequences. The component is called fault detection and diagnosis (FDI), and a process model-based algorithm is used in this study to monitor the operation of a system. Nevertheless, because stability is a primary requirement of a control system, another requirement of supervision is to guarantee the stability as well as the health of the plant. This is the theme of this paper which combines both control and supervision using GPC.
Development of a structural model of environmentally conscious manufacturing drivers

Purpose – Manufacturing firms consume energy and natural resources in highly unsustainable manner and release huge amounts of green house gases leading to many economic, environmental and social problems; from local waste disposal to climate change. Consciousness about these issues has lead to a new manufacturing paradigm of environmentally conscious manufacturing (ECM). There exist many social, legislative, policy, economic, internal, and environmental factors which can motivate and/or force industry to adopt ECM. The purpose of this paper is to identify the drivers for ECM, developing a model of these drivers using statistical analysis and testing the model using structural equation modeling (SEM) technique. Design/methodology/approach – The basic steps of methodology are ECM driver development, survey instrument development, data collection, model proposition, and model validation. The main data analysis approaches are exploratory factor analysis, confirmatory factor analysis, and SEM to develop a mode.
Information flow across the cortical timescale hierarchy during narrative construction

When listening to spoken narratives, we must integrate information over multiple, concurrent timescales, building up from words to sentences to paragraphs to a coherent narrative. Recent evidence suggests that the brain relies on a chain of hierarchically organized areas with increasing temporal receptive windows to process naturalistic narratives. We hypothesized that the structure of this cortical processing hierarchy should result in an observable sequence of response lags between networks comprising the hierarchy during narrative comprehension. This study uses functional MRI to estimate the response lags between functional networks during narrative comprehension. We use inter-subject cross-correlation analysis to capture network connectivity driven by the shared stimulus. We found a fixed temporal sequence of response lags—on the scale of several seconds—starting in early auditory areas, followed by language areas, the attention network, and lastly the default mode network. This gradient is consistent across eight distinct stories but absent in data acquired during rest or using a scrambled story stimulus, supporting our hypothesis that narrative construction gives rise to inter-network lags. Finally, we build a simple computational model for the neural dynamics underlying the construction of nested narrative features. Our simulations illustrate how the gradual accumulation of information within the boundaries of nested linguistic events, accompanied by increased activity at each level of the processing hierarchy, can give rise to the observed lag gradient. Significance Statement Our findings reveal a consistent, stimulus-driven gradient of lags in connectivity along the cortical processing hierarchy—from early auditory cortex to the language network, then to the default mode network—during the comprehension of naturalistic, spoken narratives. We provide a simple computational model for the neural dynamics underlying the construction of nested narrative features, allowing us to systematically explore the conditions under which the lag gradient emerges and synthesize our results with previous findings based on simple well-controlled language stimuli. Our results illustrate the isomorphism between hierarchically structured neural dynamics and hierarchically structured, real-world narrative inputs.
The state of the professionalisation of the records and archives management profession in Zimbabwe

The professionalisation of any given field is at the heart of establishing the records and archives management profession as well as making it visible and respected in the work space. Without professionalisation, records and archives management professionals will continue to be undermined in the workplace and thus, struggle to pursue the mission and purpose of managing records throughout their life cycle. This study sought to investigate the state of professionalisation of the records and archives management field in Zimbabwe with a view to recommending ways through which the field can work towards professionalising. A quantitative research methodology, a cross sectional survey research design and systematic random sampling otherwise known as ordinal sampling was applied.
Structural Equation Model of Trust and Partnering Success

The establishment of trust has been identified as the most critical factor that facilitates partnering success. As such, management should direct their efforts and energy to enhance trust effectively and systematically. It is hypothesized that partners’ trust level is positively related to their performance, permeability, and relational bonding and can be system based. This paper reports the use of the structural equation modeling technique to test this hypothesis. Project-based data on partnering success and the relative importance of the four trust factors were collected through a questionnaire survey, and the level of partnering success was assessed by the achievement of the preset project targets. The findings of the study support the hypothesized positive relationship between the partners’ trust level and partnering success. In addition, performance, permeability, and relational bonding were found to make significant contributions toward parties’ trust level.
Curriculum Mapping of Undergraduate Medical Programmes: Recommendations for Future Directions

Background: Medical schools are expected to churn out all-rounded healthcare professionals who are competent in the prerequisite knowledge and skills necessary to address the everchanging health needs of the society. This is usually made possible through innovation and strategy, one of which involves the continuous review and renewal of all the components of existing teaching and learning plans through a blueprinting process called curriculum mapping. This blueprint allows for curriculum goals development, together with management, reviewing and organizing its contents. As curriculum mapping of medical programmes was in its infancy stage at the time of this research, this study focusses on reporting the perspectives of the curriculum leaders on future directions for curriculum mapping of undergraduate medical programmes in South Africa. Method: Purposive sampling was used in a qualitative study among fourteen academics involved in medical curricula at all eight medical schools. Semi-structured interviews were used for data collection, and analysis was done by thematic analysis. Results: Curriculum planners have specific expectations of curriculum mapping of undergraduate programmes as a possible future strategy to drive curriculum review and renewal in the country. Although some agreement exists about the characteristic features, any mapping platform created should meet the specific institutional requirements that will address their challenges. Conclusion: Finally, a national mandate from the authorities will be required to achieve curriculum benchmarking and collaboration amongst the medical schools to standardize undergraduate medical programme outcomes.
Direct self-control (DSC) of inverter-fed induction machine

The new direct self-control (DSC) is a simple method of signal processing that gives converter-fed three-phase machines an excellent dynamic performance. To control the torque of, say, an induction motor, it is sufficient to process the measured signals of the stator currents and the total flux linkages only. In the basic version of DSC, the power semiconductors of a three-phase voltage source inverter are directly switched on and off via three Schmitt triggers, comparing the time integrals of line-to-line voltages to a reference value of desired flux, if the torque has not yet reached an upper-limit value of a two-limit torque control. Optimal performance of drive systems is accomplished in steady state as well as under transient conditions by combination of several two-limit controls. >
An effective solution to microwave arrays synthesis with null field constraints in the near-field region

This work addresses the problem of the power synthesis with null field constraints in near-field region for a large array working at microwave frequencies. It is solved as an intersection finding problem between the set of all far-field patterns which can be radiated by the considered array and the set of all functions fulfilling the pattern requirements. An alternating projection method, based on the concept of projection operator, is used to this end. The number of null field constraints is remarkably reduced by applying the recent results on the 3-D sampling representations of electromagnetic fields. Numerical tests assessing the effectiveness of the proposed technique are presented.
Employer investment in Apprenticeships in England: an exploration of the sensitivity of employers in the construction sector to the net costs of training

Apprenticeships in England are undergoing major reform which will likely require employers to make a cash contribution to meeting the fees of their training providers. In return employers will be given more influence over the content of the training. If employers are expected to make a cash contribution this is likely to have an impact on their willingness to deliver Apprenticeships. Based on a series of employer case studies conducted between 1995 and 2011 an examination is provided of construction employers’ sensitivity to the costs of delivering Apprenticeships. Because the cost to the employer is relatively high, and because there is a degree of uncertainty attached to recouping those costs, there is a distinct set of disincentives to construction employers providing Apprenticeships. This is important. First, the construction sector will need to recruit a large number of additional people into skilled trades jobs over the next 10 years as the sector’s recovery gains pace and many existing employees retire. Second, Apprenticeships in the sector have an important role to play in young people’s transition from school into work. A fall in the number of apprentices in the sector is likely to have important economic and social consequences.
Antimicrobial and Anti-Biofilm Activity of Polymyxin E Alone and in Combination with Probiotic Strains of Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895 against Clinical Isolates of Selected Acinetobacter spp.: A Preliminary Study

Acinetobacter spp. , the nosocomial pathogen, forms strong biofilms and is resistant to numerous antibiotics, causing persistent infections. This study investigates the antibacterial and anti-biofilm activity of polymyxin E alone and in combination with the cell-free supernatants (CFS) of the tested probiotic bacilli, Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895 against the selected Acinetobacter spp. starins. Three isolates of Acinetobacter spp. , designated as Acinetobacter spp. isolate 1; Acinetobacter spp. isolate 2, and Acinetobacter spp. isolate 3, were collected from patients with burns, wounds, and blood infections, respectively. Bacterial identification and antibiotic susceptibility testing were conducted using the VITEK2 system. Auto-aggregation and coaggregation of the tested bacilli strains with the selected Acinetobacter spp. isolates were evaluated. A disk diffusion assay was used to identify the microorganism’s susceptibility to the selected antibiotics, alone and in combination with the CFS of the bacilli. The MIC and MBIC (minimum inhibitory and minimum biofilm inhibitory concentrations) of polymyxin E combined with bacilli CFS were determined. Acinetobacter spp. isolates were (i) sensitive to polymyxin E, (ii) able to form a strong biofilm, and (iii) resistant to the tested antibiotics and the CFS of tested bacilli. Significant inhibition of biofilm formation was noticed when CFS of the tested bacilli were combined with polymyxin E. The bacilli CFS showed synergy with polymyxin E against planktonic cells and biofilms of the isolated pathogens.
Privacy Preserving distributed smart grid system based on Hyperledger Fabric and Wireguard

Smart grid has drawn a lot of attention and investment in recent years, which not only helps the modern generation and distribution of traditional power but also highly widens the application of renewable energy sources. However, the main challenges in the application of smart grid are 1. the privacy preservation of users' information and 2. the trustful transmission channel among peers. In order to solve these problems, VPN and blockchain can be considered since they have some features perfectly suitable for these situations. In this paper, we propose a smart grid system based on WireGuard and Hyperledger Fabric to solve the problems mentioned above. And we also implement the whole system and give a view by web application. What's more, all the functionalities are displayed and tested, including building a smart device simulator, deploying data visualization and making some performance evaluations about transactions and WireGuard communication. Experiment results show that the introduction of WireGuard into network infrastructure does not cause too much loss of bandwidth and delay, but it ensures a certain degree of communication security. And Fabric provides the consistency and traceability of transactions in smart grid system.
