Architectural Glass & Cladding has put their reputation behind the trusted and innovative products of Okalux GmbH. -- Architectural Glass & Cladding has put their reputation behind the trusted and innovative products of Okalux GmbH. Since 2010, their close partnership has helped the architectural community to discover the advantages of energy efficiency, end user comfort and the use of natural daylight to reduce the running costs of buildings throughout Australia and South East Asia."Our goal is to develop optimum solutions to satisfy architects specific demands – with glass," said Paul Nipperess, Sales and Marketing Manager of Architectural Glass & Cladding. AG&C has more than 20 years experience in the glass and façade industries."Okalux has decades of experience in the development and manufacture of high quality insulating glass for international construction projects. The very first product which sparked off the idea for the founding of the company also set the standard for its powers of innovation. Hollow fibres, which were originally conceived for the textiles industry, produce great advantages when inserted in the space between the panes of a window: they produce a soft diffusion of daylight and deep illumination of interiors," said Paul.This was followed by systems for light deflection and improved diffusion, transparent heat insulation and energy reduction. Paul goes on to say, "Glass is one of the most fascinating materials available to architects. It allows natural light into buildings and contributes decisively towards the end user's comfort. Okalux has dedicated itself to using natural light and ensuring that its products produce a balance of often contradictory demands; supplying a building with light and thermal energy while simultaneously protecting against overheating, heat loss and UV radiation." Because of this, Paul has called on architects, designers and builders to keep windows on their radar early by "creating purpose built solutions."This partnership between Okalux and Architectural Glass and Cladding has provided solutions to many key projects by utilising many of the unique and innovative Okalux products. These projects include: 570 Bourke Street Melbourne, Australian Catholic University NSW, Australian War Memorial ACT, The Peter Doherty Institute (University of Melbourne), Illumin8 Building (Adelaide University), Malaiwana Estate (Phuket Thailand), and 5 Martin Place (Sydney). Projects currently under construction include Monash University (Melbourne), and the Hong Kong Art Museum.For more information contact Architectural Glass & Cladding Pty Ltd, Suite 17, Wharf Central, 75 Wharf Street, Tweed Heads NSW 2485, phone 07 5523 2335, fax 07 5523 2336, email: email@example.com ( mailto://info@ agcproducts.com.au ), website: http://www.agcproducts.com.au

Exercise represents a major challenge to whole-body homeostasis provoking widespread perturbations in numerous cells, tissues, and organs that are caused by or are a response to the increased metabolic activity of contracting skeletal muscles. To meet this challenge, multiple integrated and often redundant responses operate to blunt the homeostatic threats generated by exercise-induced increases in muscle energy and oxygen demand. The application of molecular techniques to exercise biology has provided greater understanding of the multiplicity and complexity of cellular networks involved in exercise responses, and recent discoveries offer perspectives on the mechanisms by which muscle "communicates" with other organs and mediates the beneficial effects of exercise on health and performance. ©2014 Elsevier Inc.

Research has shown that students' learning and cognitive performance can be influenced by emotional reactions to learning, like enjoyment, anxiety, and boredom. Most studies on this topic have been done in labs. Now a new longitudinal study out of Germany investigates how students' emotions in a school context relate to their achievement. The study focused on achievement in math, which is not only important for education and economic productivity but is also known to prompt strong emotional reactions in students. The study was conducted by researchers from the University of Munich, Australian Catholic University, University of Oxford, University of Reading, University of Konstanz, and Thurgau University of Teacher Education. It appears in the journal Child Development. "We found that emotions influenced students' math achievement over the years," explains Reinhard Pekrun, professor of psychology at the University of Munich and Australian Catholic University, who led the research. "Students with higher intelligence had better grades and test scores, but those who also enjoyed and took pride in math had even better achievement. Students who experienced anger, anxiety, shame, boredom, or hopelessness had lower achievement." The research was conducted as part of the Project for the Analysis of Learning and Achievement in Mathematics (PALMA). It included annual assessments of emotions and achievement in math in 3,425 German students from grades 5 through 9. Students were representative of the student population of Bavaria, which primarily includes youth from nonimmigrant White families, but represents a broad mix of socioeconomic backgrounds and both urban and rural locations. Students' self-reported emotions were measured by questionnaires, and their achievement was assessed by year-end grades and scores on a math achievement test. The study also found that achievement affected students' emotions over time: "Successful performance in math increased students' positive emotions and decreased their negative emotions over the years," according to Stephanie Lichtenfeld, senior lecturer at the University of Munich, who coauthored the study. "In contrast, students with poor grades and test scores suffered from a decline in positive emotions and an increase in negative emotions, such as math anxiety and math boredom. Thus, these students become caught in a downward spiral of negative emotion and poor achievement." The study's finding that emotions influenced achievement held constant even after taking into account the effects of other variables, including students' intelligence and gender, and families' socioeconomic status. The results are consistent with previous studies showing that emotions and academic achievement are correlated, but they go beyond these by disentangling the directional effects underlying this link. Specifically, the research suggests that emotions influence adolescents' achievement over and above the effects of general cognitive ability and prior accomplishments, the authors note. The study's authors recommend that educators, administrators, and parents work to strengthen students' positive emotions and minimize negative emotions related to school subjects, for example, by helping students gain a greater sense of control over their performance. They also suggest that providing students with opportunities to experience success may help reduce negative feelings and facilitate emotional well-being, which can promote students' educational attainment. Future research on this topic could explore whether the pattern found here pertains to other age groups and academic subjects. The research was supported by the University of Munich and the German Research Foundation. The Society for Research in Child Development will hold its Biennial Meeting in Austin, Texas, April 6-8, 2017.

Students' cognitive performance and learning process can be influenced by emotional reactions to learning, such as boredom, enjoyment or anxiety. While most of the studies on this topic have been done in laboratories, new longitudinal research from Germany suggests that students' achievements can be influenced by school contexts. The study was focused on math achievement, which is both known to create powerful emotional reactions among students and relevant for economic productivity and education. The research, published in the journal Child Development, found that emotions impacted students' performance in math over the years. "Students with higher intelligence had better grades and test scores, but those who also enjoyed and took pride in math had even better achievement. Students who experienced anger, anxiety, shame, boredom, or hopelessness had lower achievement," noted Reinhard Pekrun, lead author of the study and professor of psychology at LMU Munich and Australian Catholic University. The study was conducted on 3,425 German students, from grades five through nine, and it involved annual assessments of achievement and emotions in math. The students' emotions were self-reported and evaluated through questionnaires, while the students' achievements were measured by the grades at the end of the school year and scores on a math achievement test. Additionally, the students were representative of Bavaria, and the research focused on non-immigrant, white families. However, among these, a wide range of socioeconomic backgrounds from rural and urban places was assessed. According to one of the researchers, good performance in math increased the positive emotions among the students and decreased the negative ones throughout the years, which means that the achievements also shaped emotions and not just vice-versa. Additionally, students who had lower test scores and grades had a lower level of positive emotions and a higher level of negative ones, such as boredom and anxiety toward math. The researchers believe that this type of association can lead to a vicious cycle when it comes to negative emotional associations and poor performance. "Negative emotions (anger, anxiety, shame, boredom, hopelessness) negatively predicted achievement, and achievement negatively predicted these emotions. The findings were robust across waves, achievement indicators, and school tracks, highlighting the importance of emotions for students' achievement and of achievement for the development of emotions," noted the research. Additionally, the research is consistent with previous studies on the matter, which showed that academic performance is correlated with emotional positioning. However, what this research brings to the table is the directional effect of negative emotions when it comes to poor grades and the duality of this correlation. Specifically, the authors of the research underlined the massive impact of adolescents' emotions on their academic performance, which is evaluated to weigh more than their grades and accomplishments. While the current research stresses the fact that school administrators and educators should work on creating positive emotional responses among students, another research suggests that parents have a lot to do with their children's performance, as well. Intrusive parenting is harmful to children and their overall performance, as another research pointed out. Children who have intrusive parents are more susceptible to anxiety and depression, and their overall school performance may have to suffer because of this form of abusive parenthood. © 2017 Tech Times, All rights reserved.

This study investigated the influence of playing standard, and winning and losing on the physical demands of elite rugby league match play. Twenty-two elite rugby league players participated in this study. Global positioning system data were collected during 16 rugby league matches. Players covered significantly greater (p ≤ 0.05) absolute and relative distance at high speeds when playing against Bottom 4 teams than when competing against Top 4 teams. The total distance per minute of match play and relative distance at low speeds were greater when matches were won. In addition, a greater absolute and relative number of maximal accelerations and repeated high-intensity effort bouts were performed when players were competing in winning teams than in losing teams. The mean and maximum number of efforts in a repeated high-intensity effort bout was also higher in winning teams, although the recovery between efforts was shorter in losing teams. Moderate (7?17 points) and large (-18 points) winning margins were associated with greater relative distances covered and distances covered at low speeds than small winning margins. No meaningful differences were found in the physical demands between small, moderate, and large losing margins. The results of this study demonstrate that the physical demands of rugby league are greater when winning than losing, and when competing against lower ranked teams. Furthermore, larger winning margins are associated with greater physical demands than small and moderate winning margins, with these physical demands, in turn, greater than losing margins of any magnitude. These findings suggest that the competitive advantage of successful elite rugby league teams is closely linked to their ability to maintain a higher playing intensity than their less successful counterparts. © 2013 National Strength and Conditioning Association.

Benefits of community-based whole-body vibration (WBV) as a mode of exercise training for people with chronic obstructive pulmonary disease (COPD) have not been investigated. The low skill demand of WBV may enhance habitual sustainability to physical activity by people with COPD, provided efficacy of WBV can be established. The purpose of this trial was to compare a community-based WBV intervention with a sham WBV (SWBV) intervention and monitor exacerbations, exercise tolerance, and functional performance of the lower limbs of people with COPD. Community-dwelling adults with a GOLD clinical diagnosis of COPD were recruited to the trial. This was a Phase II efficacy trial with crossover to sham intervention interspersed with two-week washout. Each six-week intervention consisted of two sessions per week of either WBV or SWBV. The interventions were completed in the home of each participant under supervision. The outcome measures were selected psychological (perceived dyspnoea) and physiological (heart rate and oxygen saturation) responses to exercise, simulated activities of daily living (timed-up-and got test and 5-chair stands test), and selected kinematic variables of gait across the 14-week trial. Sixteen adults with stable COPD were recruited to the trial. No exacerbations were reported during the WBV or SWBV interventions. After WBV, performance of activities of daily living (ADLs) and gait improved (p ≤ 0.05), while there was no change after SWBV (p > 0.05). Despite five withdrawals during the washout period, a 100% compliance to each six-week intervention was noted. Results showed that WBV did not exacerbate symptoms of COPD that can be associated with physical inactivity. The WBV intervention improved tests to simulate ADLs such as rising from a chair, turning, and walking gait with greater effect than a SWBV intervention. If a placebo effect was systemic to the WBV intervention, the effect was negligible. As a standalone community-based intervention, WBV was an efficacious mode of exercise training for people with stable COPD that did not negatively effect exercise tolerance or exacerbate the disease, while concurrently improving functional performance of the lower limbs.

Purpose: A limitation of most rugby league time-motion studies is that researchers have examined the demands of single teams, with no investigations of all teams in an entire competition. This study investigated the activity profiles and technical and tactical performances of successful and less-successful teams throughout an entire rugby league competition. Methods: In total, 185 rugby league players representing 11 teams from a semiprofessional competition participated in this study. Global positioning system analysis was completed across the entire season. Video footage from individual matches was also coded via notational analysis for technical and tactical performance of teams. Results: Trivial to small differences were found among Top 4, Middle 4, and Bottom 4 teams for absolute and relative total distances covered and distances covered at low speeds. Small, nonsignificant differences (P =.054, ES = 0.31) were found between groups for the distance covered sprinting, with Top 4 teams covering greater sprinting distances than Bottom 4 teams. Top 4 teams made more meters in attack and conceded fewer meters in defense than Bottom 4 teams. Bottom 4 teams had a greater percentage of slow play-the-balls in defense than Top 4 teams (74.8% ± 7.3% vs 67.2% ± 8.3%). Middle 4 teams showed the greatest reduction in high-speed running from the first to the second half (-20.4%), while Bottom 4 teams completed 14.3% more high-speed running in the second half than in the first half. Conclusion: These findings demonstrate that a combination of activity profiles and technical and tactical performance are associated with playing success in semiprofessional rugby league players. © 2014 Human Kinetics, Inc.

The aim of this study was to determine if simulation aided by media technology contributes towards an increase in knowledge, empathy, and a change in attitudes in regards to auditory hallucinations for nursing students. A convenience sample of 60 second-year undergraduate nursing students from an Australian university was invited to be part of the study. A pre-post-test design was used, with data analysed using a paired samples t-test to identify pre- and post-changes on nursing students' scores on knowledge of auditory hallucinations. Nine of the 11 questions reported statistically-significant results. The remaining two questions highlighted knowledge embedded within the curriculum, with therapeutic communication being the core work of mental health nursing. The implications for practice are that simulation aided by media technology increases the knowledge of students in regards to auditory hallucinations. © 2013 Australian College of Mental Health Nurses Inc.

Purpose: No study has investigated the frequency and nature of repeated high-intensity-effort (RHIE) bouts across elite and semielite rugby league competitions. This study examined RHIE activity in rugby league match play across playing standards. Participants: 36 elite and 64 semielite rugby league players. Methods: Global positioning system analysis was completed during 17 elite and 14 semielite matches. Results: The most commonly occurring RHIE bouts involved 2 efforts (2-RHIE) for both elite and semielite players. Only small differences were found in 2-RHIE activity between elite and semielite match play (effect size [ES] ≥0.31 ± 0.15, ≥88%, likely). RHIE bouts were more likely to involve contact as the number of efforts in a bout increased (ES ≥0.40 ± 0.15, 100%, almost certainly). Semielite players performed a greater proportion of 2-contact-effort RHIE bouts than their elite counterparts (68.2% vs 60.6%, ES 0.33 ± 0.15, 92%, likely), while elite players performed a greater proportion of 3-effort bouts (26.9% vs 21.1%, ES 0.31 ± 0.15, 88%, likely). Elite players also had a shorter recovery (1.00-3.99 vs ≥4.00 min) between RHIE bouts (ES ≥1.60 ± 0.71, ≥94%, likely). Conclusion: These findings highlight the RHIE demands of elite and semielite rugby league match play. Elite players are more likely to perform RHIE bouts consisting of 3 efforts and to have a shorter recovery time between bouts. Exposing players to these RHIE demands in training is likely to improve their ability to tolerate the most demanding passages of match play. © 2015 Human Kinetics, Inc.

Herbal medicine interventions have been identified as having potential benefit in the treatment of rheumatoid arthritis (RA). To update an existing systematic (Cochrane) review of herbal therapies in RA. We searched electronic databases Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, AMED, CINAHL, Web of Science, Dissertation Abstracts (1996 to 2009), unrestricted by language, and the WHO International Clinical Trials Registry Platform in October 2010. Randomised controlled trials of herbal interventions compared with placebo or active controls in RA. Two authors selected trials for inclusion, assessed risk of bias and extracted data. Twelve new studies were added to the update, a total of 22 studies were included.Evidence from seven studies indicate potential benefits of gamma linolenic acid (GLA) from evening primrose oil, borage seed oil, or blackcurrent seed oil, in terms of reduced pain intensity (mean difference (MD) -32.83 points, 95% confidence interval (CI) -56.25 to -9.42,100 point pain scale); improved disability (MD -15.75% 95% CI -27.06 to -4.44%); and an increase in adverse events (GLA 20% versus placebo 3%), that was not statistically different (relative risk 4.24, 95% CI 0.78 to 22.99).Three studies compared Tripterygium wilfordii (thunder god vine) to placebo and one to sulfasalazine and indicated improvements in some outcomes, but data could not be pooled due to differing interventions, comparisons and outcomes. One study reported serious side effects with oral Tripterygium wilfordii Hook F. In the follow-up studies, all side effects were mild to moderate and resolved after the intervention ceased. Two studies compared Phytodolor(®) N to placebo but poor reporting limited data extraction. The remaining studies each considered differing herbal interventions. Several herbal interventions are inadequately justified by single studies or non-comparable studies in the treatment of rheumatoid arthritis. There is moderate evidence that oils containing GLA (evening primrose, borage, or blackcurrant seed oil) afford some benefit in relieving symptoms for RA, while evidence for Phytodolor® N is less convincing.Tripterygium wilfordii products may reduce some RA symptoms, however, oral use may be associated with several side effects. Many trials of herbal therapies are hampered by research design flaws and inadequate reporting. Further investigation of each herbal therapy is warranted, particularly via well designed, fully powered, confirmatory clinical trials that use American College of Rheumatology improvement criteria to measure outcomes and report results according to CONSORT guidelines.
