Physical fitness of rhythmic gymnasts depending on age and level of sports achievements

Aim. The aim of this study was to compare the indices of physical development, frequency and time duration of training, and the results of physical fitness tests depending on age and level of sports achievements among rhythmic gymnasts. Materials and methods. The study comprised 36 rhythmic gymnasts: Gr1 (n=13, 9.0±1.0 years), Gr2 (n=11, 11.36±0.5 years), Gr3 (n=12, 14.27±0.7 years). After standardised sports interview, the groups with lower level of sports achievements (LSL) (n=20) and higher level of sports achievements (HSL) (n=16) were defined. Measurements of body height and mass were performed. The study participants performed the broad jump test, Unipedal Stance Test with Eyes Open (UPST-EO) and Eyes Closed (EC), and the rhythmic gymnastics specific coordinative test with a hoop. Results. The number of training sessions per week and their duration did not depend on age. The results of the broad jump were significantly different for groups Gr1, Gr2 and Gr3 (F=27.02, p<0.01). The average results for the 3 trials of UPST-EO in Gr2 and Gr3 were better than in Gr1 (F=5.51, p=0.008). The average result of UPST-EC for Gr3 was also significantly better than for Gr1 (W=9.53, p=0.008). The hoop test showed differences for all age groups Gr1<Gr3<Gr2 (F=11.55, p<0.001). HSL athletes were significantly different from LSL in frequency and duration of training, average results from 3 trials of UPST-EO, UPSTEC and the best result of UPST-EC (p<0.05). Conclusions. Differences between groups in physical fitness tests results depended on gymnasts’ age and showed their usefulness in the control of training at a particular stage of sports development. HSL gymnasts predominated over LSL in results of the one-leg standing position postural balance test with eyes opened and closed. The detected differences can be useful for coaches in identifying and developing gymnastic talent.
Exploring Reflections of Lecturers on Ethics in the Accounting Curriculum: A Case Study of Ukzn and Unizulu, South Africa

The accounting profession has changed considerably over the past twenty years or so. This has led to the new accounting curriculum undergoing many changes such as increased financial fraud coverage, laws relating to financial crime and globalisation and financial security issues. However, there have been many financial scandals in the 21 century in the African and American context. Several notable incidents of ethical misconduct such as Enron, Klynveld Peat Marwick Goerdeler (KPMG), and Satyam (which negatively impact the world economy) are examples of misuse of accounting to cover the truth. Lack of ethics is believed to be responsible for most of these scandals. This study, therefore, aims at understanding the reflections on the issue of ethics in teaching accounting. The study followed a case study approach and involved a small sample of accounting lecturers from UKZN and UNIZULU. The study's findings suggest that special topical issues on ethics should be taught in each accounting course. For example, in the auditing course, ethical procedures should be touched upon, and students should be sensitized about accountants' ethical behaviour.

A feasible multilayer structure design for solid lubricant coatings in a lunar environment

Solid lubricant coatings have received considerable research attention in space applications owing to their remarkably improved tribological characteristics. But their service life is seriously restricted by the harsh environment, such as high vacuum and abrasive wear. In this paper, a novel design of carbon-based multilayer (MoS2/DLC multilayer) coatings was reported to clarify the friction and wear behavior in high vacuum conditions with and without simulated lunar-dust (SLD). Compared with pure DLC or MoS2 coatings, the multilayer coating showed excellent tribological performance with a low friction coefficient of 0.02 and a wear rate of ∼6.5 × 10−6 mm3 N−1 m−1. What is particularly interesting is that the wear volume of MoS2/DLC multilayer coatings with the increase of time is in accordance with the Archard linear law, regardless of the condition with or without SLD. Moreover, the surface morphology and composition of wear tracks and scars reveal that the long life of carbon-based multilayer coatings cannot be explained solely by excellent mechanical performance, and is also attributed to the formation of ridge layers as third body reservoirs and a tribo-induced composite transfer layer containing SLD nanoparticles and coating materials.
ASSESSMENT OF THE EFFECT OF α-LIPOIC ACID SUPPLEMENTATION TO THE DIET WITH DIFFERENT DIETARY ENERGY LEVELS ON BROILER PERFORMANCE AND ATIOXIDANTS STATUS

The present study aimed to assess if there is any synergistic or antagonistic effect between α-lipoic acid (ALA) and dietary energy levels in increasing growth performance traits as well as minimizing fat deposition of broiler. Three hundred and sixty one-day-old unsexed Cobb broilers chicks were assigned randomly to 8 equal experimental groups; with three replicates of 15 chicks each. The feeding consists of three stages; the first was (starting period), its basal diet contained 22 % CP and lasted for 3 weeks. The second was (growing period), its basal diet contained 20 % CP and lasted for 2 weeks. The third period was (finishing period), its basal diet contained 18 % CP at the last week of the experiment. Within each protein level used, two levels of energy (3000 and 3200 Kcal / kg diet) were tested with various levels of α-lipoic acid (0, 50, 75 and 100 mg / kg diet). So, the experimental design was a factorial 2 energy levels × 4 α-lipoic acid levels. Results showed that, Significant effects of α-Lipoic acid, diet energy levels and their interaction on chicks weight gain (WG), feed consumption (FC), and feed conversion ratio (FCR). Significant declines in dressing, front part, hind part, giblets, and abdominal fat with increasing α-Lipoic acid level in the diet. Muscle (thigh and breast) antioxidants statuses were vary significantly with α-Lipoic acid, diet energy level, and their interaction. Overall, blood total lipids, triglycerides, and cholesterols have decreased significantly with increasing α-Lipoic acid levels. Moreover, only total lipids increased with increased dietary energy. Remarkable improvements were noticed in the plasma oxidative statues including TAC, SOD, GSH-px, and MDA. From the obtained results, it could be concluded that ɑ-lipoic acid supplementation at the level of 100 mg/kg diet provides significant natural antioxidant which boosts the oxidative status of meat and blood regardless the energy level in the diet.

Achieving Sustainable Development in Business: The Implementation of Environmental Management Practices by Small and Medium Enterprises

Over the past two decades, the issue of sustainability has received mixed opinions from people, especially in business world. The concept of Sustainable Development has slowly changing the view of modernisation and growth for worldwide development activities. Small and Medium-sized Enterprises (SMEs) tend to be opposed to the idea. The purpose of this study is to evaluate the implementation of Environmental Management Practices (EMP) among SMEs in Malaysia. Using the Data Envelopment Analysis (DEA) model, this study employed barriers and motivations as an input, while sustainable development elements are taken as an output. Findings show that the implementation level of EMP varied among companies, which consequently influences their level of sustainable development. The implications of the finding are discussed based on the concept of Goal-Setting Theory to explain the nexus between the company’s ability to set the right environmental goals and employees’ understanding of the signals sent to support the company’s sustainable development.
Politeness and University Student Online Communication

Modern university students are expected to participate in online discussions as part of their course work as well as write emails to professors requesting meetings and explaining late paper submissions. These online written interactions require students to demonstrate advanced written pragmatic competence in English to effectively manage their relationships and studies at English medium of instruction (EMI) universities. It is therefore important for undergraduate English as second language (L2) learners to understand how politeness is expressed in online communication. However, politeness is a facet of language use which is often difficult to master because it is dependent on the relationship between the interactants and is culturally and contextually bound (Haugh, 2007). This paper discusses politeness theory and research and considers how politeness is expressed and interpreted in computer-mediated communication (CMC) in EMI university contexts.
English summary MODALITY IN DRUG INFORMATION LEAFLETS : A CORPUS-BASED ANALYSIS

Introduction The genre of drug information leaflets is a common way of giving useful pieces of information to patients using the medicine on the amount, way, expected side effects and hoped positive outcome of using a particular medicine. On the other hand, these documents may also serve as a special means of self-defence used by drug manufacturers for preventing legal action taken against them by unsatisfied, disappointed, or even damaged patients. The role of the linguistic phenomenon of modality in these efforts is the main focus of the present study. The identification, interpretation and classification of the manifestations of modality are meant to be a useful contribution between the two traditional partners: patients and drug manufacturers.

Job Burnout in Front-Line Employees: Moderating Role of Hope and Self-Efficacy

The present study investigates the effects of burnout toward job performance and job satisfaction with a moderating role of hope and self-efficacy. Findings from 310 frontline employees of Pakistani commercial bank (Lahore, Karachi & Islamabad), showed burnout has a significant negative effect on job performance and job satisfaction. A simple random sampling technique was used to collect data, and inferential statistics were applied to analyze the data. However, results disclose no moderation effect of hope on burnout and job performance or with job satisfaction. But, data significantly support the moderation effect of self-efficacy. The moderation effect was analyzed by the moderation process of Preacher, Rucker, & Hayes, (2007). The study further sheds light on the development of psychological capital, and the importance of the implication of the current finding is discussed. This study will help top management and trainers to understand so they can manage burnout issues on frontline employees for better performance and employee satisfaction.

Large‐Area Compliant, Low‐Cost, and Versatile Pressure‐Sensing Platform Based on Microcrack‐Designed Carbon Black@Polyurethane Sponge for Human–Machine Interfacing

It is a challenge to manufacture pressure‐sensing materials that possess flexibility, high sensitivity, large‐area compliance, and capability to detect both tiny and large motions for the development of artificial intelligence products. Herein, a very simple and low‐cost approach is proposed to fabricate versatile pressure sensors based on microcrack‐designed carbon black (CB)@polyurethane (PU) sponges via natural polymer‐mediated water‐based layer‐by‐layer assembly. These sensors are capable of satisfying the requirements of ultrasmall as well as large motion monitoring. The versatility of these sensors benefits from two aspects: microcrack junction sensing mechanism for tiny motion detecting (91 Pa pressure, 0.2% strain) inspired by the spider sensory system and compressive contact of CB@PU conductive backbones for large motion monitoring (16.4 kPa pressure, 60% strain). Furthermore, these sensors exhibit excellent flexibility, fast response times (<20 ms), as well as good reproducibility over 50 000 cycles. This study also demonstrates the versatility of these sensors for various applications, ranging from speech recognition, health monitoring, bodily motion detection to artificial electronic skin. The desirable comprehensive performance of our sensors, which is comparable to the recently reported pressure‐sensing devices, together with their significant advantages of low‐cost, easy fabrication, especially versatility, makes them attractive in the future of artificial intelligence.
Inter-comparison of snow depth over Arctic sea ice from reanalysis reconstructions and satellite retrieval

Abstract. In this study, we compare eight recently developed snow depth products over Arctic sea ice, which use satellite observations, modeling, or a combination of satellite and modeling approaches. These products are further compared against various ground-truth observations, including those from ice mass balance observations and airborne measurements. Large mean snow depth discrepancies are observed over the Atlantic and Canadian Arctic sectors. The differences between climatology and the snow products early in winter could be in part a result of the delaying in Arctic ice formation that reduces early snow accumulation, leading to shallower snowpacks at the start of the freeze-up season. These differences persist through spring despite overall more winter snow accumulation in the reanalysis-based products than in the climatologies. Among the products evaluated, the University of Washington (UW) snow depth product produces the deepest spring (March–April) snowpacks, while the snow product from the Danish Meteorological Institute (DMI) provides the shallowest spring snow depths. Most snow products show significant correlation with snow depths retrieved from Operational IceBridge (OIB) while correlations are quite low against buoy measurements, with no correlation and very low variability from University of Bremen and DMI products. Inconsistencies in reconstructed snow depth among the products, as well as differences between these products and in situ and airborne observations, can be partially attributed to differences in effective footprint and spatial–temporal coverage, as well as insufficient observations for validation/bias adjustments. Our results highlight the need for more targeted Arctic surveys over different spatial and temporal scales to allow for a more systematic comparison and fusion of airborne, in situ and remote sensing observations.
