Abstract: This paper presents a comprehensive analysis of the effects of electronic devices and social media in the prospects of Australian higher education, teaching and learning. The purpose of this research is to discover teaching and learning when electronic devices and social media are implemented and integrated in Australian educaN2o3e4liaztion. This paper mainly has used secondary research data and methods to provide a broad investigation of teaching and learning with electronic devices and the roles social media play. The research is subject to academic journal articles, project reports, media articles, corporation based documents and other appropriate information. The study found that electronic devices and social media present both opportunities and challenges to higher education. In addition, they offer advantages for student learning and frustrations from learning with electronic devices. One of the most important advantages is the ability to access information quickly and conveniently such as accessing course contents such a discussion boards, course readings, and video clips they need to watch for class on their mobile devices. In addition, they use their devices to upload and post content to course sites. Overall, the students found using mobile devices very convenient. Also constant connectivity among the devices helps the students to communicate with fellow classmates and the teachers. Social media such as Face book, Twitter have allowed students to share their thoughts immediately with their classmates within the course of their everyday lives. Finally the review found that though Australian students have considered electronic devices helpful, frustrations from learning with the devices are obvious which include anti-technology instructors in other classes, e-device challenges, and devices as a distraction.Keywords: Electronic Devices; Social Media; Higher Education; Teaching & Learning; Australia. Resumen:Este artículo presenta un análisis exhaustivo de los efectos de los dispositivos electrónicos y las redes sociales en las perspectivas de la educación superior, la enseñanza y el aprendizaje australianos.

Re-Thinking Vygotsky: Applying Social Constructivism to Asynchronous Online Courses utilizing the Power of Crowdsourcing

Web 2.0 technologies have dramatically changed the way businesses communicate today and the rise of crowdsourcing is largely seen as an online, distributed model for problem-solving across industries. The maturity of web 2.0 technologies has also increased learners’ interest in online courses. However, the results obtained from online courses are highly debatable in terms of motivation, course completion rates and actual learning that occur. This paper is a call to apply social constructivism approach to online courses, using the power of crowdsourcing to collect educational resources around online courses and using crowd workers as More Knowledgeable Others (MKO’s) in online one-on-one settings to maximize learner’s satisfaction and learning

The use of Prepared Zeolite Y from Iraqi kaolin for Fluid Catalytic Cracking of Vacuum Gas Oil

The faujasite type Y zeolite catalyst was prepared from locally available kaolin. For prepared faujasite type NaY zeolite X-ray, FT-IR, BET pore volume and surface area, and silica/ alumina were determined. The Xray and FT-IR show the compatibility of prepared catalyst with the general structure of standard zeolite Y. BET test shows that the surface area and pore volume of prepared catalyst were 360 m2 /g and 0.39 cm3 /g respectively. The prepared faujasite type NaY zeolite modified by exchanging sodium ion with ammonium ion using ammonium nitrate and then ammonium ion converted to hydrogen ion. The maximum sodium ion exchange with ammonium ion was 53.6%. The catalytic activity of prepared faujasite type NaY, NaNH4Y and NaHY zeolites was investigated by using the experimental laboratory plant scale of fluidized bed reactor. The cracking process was carried out in the temperature range 440 to 500 o C, weight hourly space velocity (WHSV) range 10 to 25 h-1 ,and atmospheric pressure . The catalytic activities of the prepared faujasite type NaY , NaNH4Y and NaHY zeolites were determined in terms of vacuum gas oil (VGO) conversion, and gasoline yield . The conversion at 500o C and WHSV10 hr-1 by using faujasite type NaY, NaNH4Y and NaHY zeolite were 50.2%, 64.1% and 69.5wt% respectively. The gasoline yield using the same operating conditions were 24.8%, 30.5% and 36.8wt% respectively

The rapid development of the food establishment industry witnessed the online reviews for restaurants becoming a significant tools for restaurant owners to increase their sales, image and customers. Thus, this research is conducted to measure the effect of online reviews on intention to visit restaurants. The study was conducted by distributing a self administered questionnaire involving 156 respondents and analyzed using Statistical Package for the Social Sciences (SPSS) version 20. All variables measured was significantly influence the consumer's intention to visit restaurants, especially in terms of positive online reviews (eWOM), negative online reviews (eWOM) and online food quality reviews. Moreover, the results showed a positive relationship between positive online reviews, negative online reviews and food towards consumer intention to visit restaurant. The result also demonstrated that food quality online reviews was least effected on consumer intention to visit restaurant with lowest correlation value. The study confirmed that the online reviews became crutial in improving the quality of sales, image, food and also service of the restaurant

Discharge Coefficient of Contracted Rectangular Sharp-Crested Weirs, an Experimental Study

An experimental study is made here to investigate the discharge coefficient for contracted rectangular Sharp crested weirs. Three Models are used, each with different weir width to flume width ratios (0.333, 0.5, and 0.666). The experimental work is conducted in a standard flume with high-precision head and flow measuring devices. Results are used to find a dimensionless equation for the discharge coefficient variation with geometrical, flow, and fluid properties. These are the ratio of the total head to the weir height, the ratio of the contracted weir width to the flume width, the ratio of the total head to the contracted width, and Reynolds and Weber numbers. Results show that the relationship between the discharge coefficient and these variables is a non-linear power function with a determination coefficient of 0.97. The importance and normalized importance analysis show that 56.3 % of the discharge coefficient variation is explained by the head-to-contracted width of the weir ratio followed by lower effects of the other variables, namely 16.5, 13.7, 12.4, and 1.2 % for contracted width to flume width ratio, Reynolds number, the head to the contracted width ratio, and Weber, respectively. The effect of the Weber number on the discharge coefficient is much lower than that of the Reynolds number

A review of building integrated photovoltaic: case study of tropical climatic regions

The building integrated photovoltaic (BIPV) system have recently drawn interest and have demonstrated high potential to assist building owners supply both thermal and electrical loads. In this paper, the BIPV technology has been reviewed, in terms of its performance, efficiency and power generation capacity. Specifically, the applications of the BIPV in tropical climate regions have been discussed, together with its prospects and challenges. For these schemes to be implemented in a tropical climatic region, the following issues must be considered: 1) Certain studies must be done relating to electrical load demand, predicted PV output, location of the buildings and its integration and constraints associated with roof design; 2) For the highest energy production from solar PV, the solar collectors need to be with the right tilt depending on the location; 3) Design criteria such as safety, efficiency, durability, flexibility and constructive issues need to be considered; 4) The government of such countries must train electricians and carpenters on PV installations; 5) The BIPV roofing must perform same function as normal roofing materials, such as noise protection, water tightness, insulation and climate protection, and 6) As practiced around the world, these countries must establish design standards for the BIPV

Evaluation of adjunctive HPV testing by Hybrid Capture II(® )in women with minor cytological abnormalities for the diagnosis of CIN2/3 and cost comparison with colposcopy

BACKGROUND: As a proportion of high grade cervical intraepithelial neoplasia (CIN2/3) are associated with equivocal cervical smears, which show borderline or mild dyskaryosis, follow up with repeat smears, colposcopy and biopsy is required. Since infection with oncogenic Human Papilloma Virus (HR HPV) has been found to be associated with the development of cervical cancer, HRHPV testing appears to be an alternative. OBJECTIVE: The present study assesses if HRHPV testing can predict CIN2/3 in women referred for mild dyskaryosis and borderline cytological changes in an health authority with a referral policy to colposcopy after one single mild dyskaryotic Pap smear. STUDY DESIGN: The HPV DNA Hybrid Capture II (Digene/Abbott, Maidenhead) was evaluated on 110 consenting women with mild dyskaryosis and 23 women with persistent borderline changes, who were referred for colposcopy between May and November 2001. A cost comparison between two referral policies was performed. RESULTS: CIN2/3 was diagnosed histologically in 30 of 133 women (22%) with minor cytological abnormalities. As the Receiver Operator Characteristics plot suggested a cut-off of 3 pg/ml the HRHPV HCII was evaluated at 3 RLU (relative light units) and at the manufacturer's recommendation of 1 RLU. At both cut-offs sensitivity and negative predictive value were high at 97%. Specificity was low at 37% at a cut-off of 1 pg/ml and 46% at a cut-off of 3 RLU. To remain cost neutral in comparison to immediate colposcopy the costs for one HR HPV HC II must not exceed £34.37 per test at a cut off of 3 pg/ml. CONCLUSION: The negative likelihood ratio (NLR) was of good diagnostic value with 0.089 at 1 RLU and 0.072 at 3 RLU, which reduces the post-test probability for CIN2/3 to 2% in this population. Women with minor cytological disorders can be excluded from colposcopy on a negative HR HPV result. Specificity can be improved by restricting HR HPV testing to women with persistent borderline cytological changes or to women over 30 years

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
