Effect of case–based video support on cyberbullying awareness

When it comes to safe and ethical information technology use, cyberbullying stands out. Indeed, it is seen to be a prevalent and complex problem. Prevention suggestions tend to rely on implications of descriptive and correlational studies rather than true experimental works. In this regard, the current study investigated the effect of case–based video (CBV) support on empowering cyberbullying awareness among 120 pre–service information technology teachers. Solomon four–group design was used in which four groups of students were randomly assigned to two treatment conditions. In the experimental groups, CBVs on authentic victimization instances were integrated into the instructional module on cyberbullying. The same cases and the content were provided without the CBV support in the control groups. One group from each condition was pretested before the implementation. Following the treatment, all groups were post–tested through a one–factor cyberbullying awareness scale. Two–way ANOVAs were used to analyze the data. Findings revealed that both types of instructional modules were useful whereas the CBVs led to better outcomes. Findings are discussed with regard to the relevant literature and suggestions for further studies are provided.
Bio-agronomic characterization of twelve plum cultivars on two clonal rootstocks in a semi-arid environment in Sicily

Introduction . Plum cultivation in Southern Italy is of great interest due to the possibility of obtaining produce over an extended period using early and late varieties. The objective of this study was to choose the best combination of cultivars and rootstock to make the production period as long as possible. Materials and methods. The influence of two rootstocks i.e. Myrobalan 29C (Prunus cerasifera Ehrn.) and Montclar® [Prunus persica (L.) Batsch] on growth, yield and fruit quality of nine Japanese and three European plum cultivars was evaluated. Results and discussion. Four years after planting, the trees on Montclar® rootstock displayed higher vigour. The highest yield was recorded on Shiro and Obilnaya grafted on both rootstocks. Black Amber produced the largest fruit and Obilnaya the smallest. Conclusion. This research contributed to identifying the most promising cultivars to be successfully grown in Southern Italy.
The structure of monohydrocalcite and the phase composition of the beachrock deposits of Lake Butler and Lake Fellmongery, South Australia

Abstract Samples of beachrock from Lakes Butler and Fellmongery, near Robe, South Australia, were examined by neutron and X-ray powder diffraction. Considerable variation in phase composition was observed, although all samples possessed monohydrocalcite, calcite, aragonite, and magnesiancalcite. The Rietveld refinement of the structure of monohydrocalcite showed significant changes in the orientation of water molecules and a major change in the orientation of a carbonate group with respect to the currently accepted structure. The current refinement shows that the hydrogen-bonding structure consists of three distinct networks, with each of the three carbonate groups being bonded to a single water molecule via one linear and one bifurcated hydrogen bond.
Pathway for student self-development: a learning orientated internship approach

Higher education is facing new challenges in preparing students for the workforce. As demands increase for students to differentiate themselves when seeking employment, it becomes necessary for higher education and vocational providers not only to understand these challenges, but also to provide a pathway for students to develop the skills necessary to become sought-after employees. This paper presents a learning orientated internship approach as one such pathway that aims to provide students, as adult learners, with the opportunity to apply their knowledge and gain new skills in a work context. The paper provides insight into students self-reported learning outcomes after undertaking the learning orientated internship program. Preliminary findings reveal that communication, interpersonal skills and personal insights are common areas of self-development through this program.
Climate projections of future extreme events in Malaysia

In Malaysia, extreme rainfall events are often linked to a number of environmental disasters such as landslides, monsoonal and flash floods. In response to the negative impacts of such disaster, studies assessing the changes and projections of extreme rainfall are vital in order to gather climate change information for better management of hydrological processes. This study investigates the changes and projections of extreme rainfall over Peninsular Malaysia for the period 2081-2100 based on the RCP 6.0 scenario. In particular, this study adopted the statistical downscaling method which enables high resolution, such as hourly data, to be used for the input. Short duration and high intensity convective rainfall is a normal feature of tropical rainfall especially in the western part of the peninsular. The proposed method, the Advanced Weather Generator model is constructed based on thirty years of hourly rainfall data from forty stations. To account for uncertainties, an ensemble multi-model of five General Circulation Model realizations is chosen to generate projections of extreme rainfall for the period 2081-2100. Results of the study indicate a possible increase in future extreme events for both the hourly and 24 h extreme rainfall with the latter showing a wider spatial distribution of increase.
Thermal modeling of carbon-epoxy laminates in fire environments.

A thermal model is developed for the response of carbon-epoxy composite laminates in fire environments. The model is based on a porous media description that includes the effects of gas transport within the laminate along with swelling. Model comparisons are conducted against the data from Quintere et al. Simulations are conducted for both coupon level and intermediate scale one-sided heating tests. Comparisons of the heat release rate (HRR) as well as the final products (mass fractions, volume percentages, porosity, etc.) are conducted. Overall, the agreement between available the data and model is excellent considering the simplified approximations to account for flame heat flux. A sensitivity study using a newly developed swelling model shows the importance of accounting for laminate expansion for the prediction of burnout. Excellent agreement is observed between the model and data of the final product composition that includes porosity, mass fractions and volume expansion ratio.
INDEPENDENT SETS OF SOME GRAPHS ASSOCIATED TO COMMUTATIVE RINGS

Let G = (V,E) be a simple graph. A set S ⊆ V is independent set of G, if no two vertices of S are adjacent. The independence number α(G) is the size of a maximum independent set in the graph. In this paper we study and characterize the independent sets of the zero-divisor graph Γ(R) and ideal-based zero-divisor graph ΓI(R) of a commutative ring R.
RAB31 (Ras-related protein in brain 31)

Rab31 is a member of the large Rab protein family (66 human members) of the Ras superfamily of small GTPases. Rab31 is expressed fairly ubiquitously in normal human tissue and regulates membrane traffic between the Golgi/TGN and the plasma membrane and/or endosomes. Dysregulated expression of Rab31 has not only been observed in several types of cancer, including breast, ovarian, cervical and liver cancer as well as glioblastoma, but also in skin diseases such as psoriasis and atopic dermatitis.
The Politics of the Principal: Influencing Teachers' School Based Decision Making. Draft.

This paper presents findings.of 1 case study that explored the micropolitical strategies used by a principal to influence teachers in a school-based decision making context. The selected suburban school was located in the south-central area of Texas and had utilized school-based management for five months. The principal was recommended as effective in facilitating participative decision making. Data were collected through extensive interviews and participant observation. Findings indicate that the principal influenced teachers through the manipulation of teacher suggestions, the use of voting techniques, the planting of information, the exchange of principal favor and support for desired teacher behaviors, and the use of expert knowledge. This paper hopes to contribute to an understanding of the political nature of principal-teacher relationships, and to address other educational administration issues, such as professional role expectations, role transit;ons, and role strain.

RICE HUSK ASH REFRACTORY: THE TEMPERATURE DEPENDENT CRYSTALLINE PHASE ASPECTS

Cylindrical blocks of Rice Husk Ash thermal insulators were made using die pressing method. The husks were burnt in an open environment and the resulting black ash heated in a carbolite furnace at a controlled temperature of 650 O C. The initial impurities of the resulting milky white RHA were determined by XRF technique. The RHA were subsequently mixed with binders and sintered at a temperature range of 1000 to 1400 O C. X-ray diffraction (XRD) Spectroscopy was carried out to determine the major crystallographic phases. Two crystalline silica phases, tridymite and cristobalite were dominant. Crystallite size of the insulators at this range of temperature varies from 6nm to 10.02nm depending on the dominant phase.
Effect of Sodium Fluoride Administration During Pregnancy and Lactation on the Structure of the Submandibular Gland in Rat Offspring

Aim of the work: This study was carried out to investigate the effect of gestational and lactational administration of sodium fluoride on the rat submandibular gland and its reversibility after fluoride withdrawal. Materials and Methods: Thirty mature female albino rats were used and allowed for mating. Then the known pregnant rats were divided into three groups. The control group (group I) and their offspring were sacrificed at the age of two months. The treated group (group II) received a daily oral dose of 40mg/kg body weight sodium fluoride dissolved in distilled water via gastric tube. Drug administration started from the gestational day 10 up to the weaning on the postnatal day 21 then their offspring were administered the drug up to the age of two months then they were sacrificed. The third group(rehabilitated group) was treated in the same regimen as the second group, but their offspring were left without treatment after the weaning on the postnatal day 21 then they were sacrificed at the age of two months. Samples of the submandibular salivary gland were taken and prepared for light and electron microscopic studies. Histomorphometric technique was done to estimate the height, diameter and volume proportion of submandibular acinar and striated duct cells. Results: Prominent changes were observed in the granular convoluted tubules (GCTs), in the acini and in the striated ducts. There was reduction in the amount of secretory granules content of the GCT of the sodium fluoride treated group. This reduction was associated with signs of degeneration and vacuolation of the cytoplasm. The GCT cells showed irregular contour of cell nuclei with clumping of the nuclear chromatin. Destruction of the mitochondria can be noticed in these cells. The acinar and striated duct cells showed degenerative changes in the form of irregular dark nuclei, variable staining and vacuolation of the cytoplasm and damaged mitochondria. Dissociation of cells from the basement membrane can be detected. On the other hand withdrawal of sodium fluoride reduced to a marked degree the structural changes induced by sodium fluoride. Conclusion: It is concluded that administration of sodium fluoride in high dose in drinking water is associated with induction of destructive effect on the structure of the submandibular salivary gland. Withdrawal of sodium fluoride exposure can lead to recovery of the toxic effects of fluoride
Optical Properties and Stability of Bilayer Rubrene-Alq3 Films Fabricated by Vacuum Deposition

We report on the optical and structural characterization of the two-component vacuum deposited (VD) rubrene (Rub)-Alq3 films. As is known, Rub-doped OLED active materials demonstrate both promising electroluminescence and transistor characteristics. However, in terms of operational lifetime, the Rub practical application in basic devices has a few draw-backs related to its chemical instability. Our main attention was focused on the role of the Alq3 coverage and the isomeric transformation of a Rub molecule on its chemical stability in these structures. By monitoring the evolution of PL emission in time, we found that the Rub degradation in Rub-Alq3 films is slower than that in vacuum-deposited Rub layers. These results demonstrate that the deposition of an Alq3 layer can be a way to enhance the stability of Rub to the photo-oxidation in optoelectronic devices. The Rub amorphous film crystallization at elevated temperatures in open air was observed for the first time.
Modelling the effect of inflation: growth, levels, and Tobin.

The negative effect of inflation on the output growth rate has been found in panel studies that avoid biases of previous cross section work. Theoretically this effect is supported qualitatively by endogenous growth exchange economies. Related research examines Tobin-type effects of inflation on the levels of various variables, such as capital usage. A coherent explanation of both growth and level effects theoretically still is lacking. We present a model to do this and find an explanation for both the growth effect and a set of inflation-induced phenomena that can be thought of as a revised Tobin effect. A basic link between the magnitude of the growth and the level effects is the degree to which inflation affects the real wage to real interest rate ratio, and this depends on the magnitude of the interest elasticity of money demand. Inflation acts as a tax on market earnings that raises the real wage rate relative to the real interest rate, lowers the growth rate, and increases the capital/labor intensities across sectors, to a degree inversely dependent on the magnitude of the interest elasticity. In addition our micro-founded exchange technology qualitatively explains some basic postwar monetary facts, and we compare this technology to more standard money/credit exchange technologies. Together the effects of inflation present a candidate monetary explanation for the postwar rise and fall of stagflation, including a wide range of effects that can be described as Tobin-related.
The Physical Conditions and Age Indicated by the Flora of the Alum Bluff Formation

The Alum Bluff formation was named from the bluff of that name on the east bank of the Apalachicola River, about 25 miles below Chattahoochee or River Junction, in Liberty County, Fla.t (See Pl. VII, B, p. 56.) It is, according to present knowledge, the uppermost formation of the Apalachicola group. It comprises three members, which, named in ascending order, are the Chipola marl member, the Oak Grove sand member, and the Shoal River marl member. The Chipola marl, which is a thin yellowish clay marl at the base of the formation as defined by Matson. and Clapp, carries a very extensive and well-preserved marine fauna. It was named from Chipola River, in Calhoun County, Fla. The Oak Grove sand, stratigraphically intermediate between the Chipola and Shoal River, is a thin, highly fossiliferous gray or greenish fine sand named from Oak Grove, on Yellow River, and not represented by a lithologic unit at Alum Bluff. The Shoal River marl, the highest known fossiliferous member
Effect of Human Beta Defensin-2 in Epithelial Cell Lines Infected with Respiratory Viruses

β-defensins are a family of antimicrobial molecules involved in inflammatory processes and infections. In human airways, β-defensin-2 (hβD-2) is the best characterized in bacterial and fungal infections; however, it has been insufficiently studied in viral infections. The respiratory syncytial virus (RSV) and adenoviruses (ADV) are important agents of acute respiratory infections. The aim of this study was to measure in vitro the production and antiviral activity of hβD-2 in HEp-2 cells and A549 cells infected with ADV and RSV; hβD-2 production at different times was assessed by RT-PCR, and its presence by immunodetection assay (Western blot) using antibodies anti-hβD-2. The effect of this defensin on viral replication was determined using recombinant hβD-2 in plaque assays. The results revealed that in the cell lines production of hβD-2is up regulated after ADV or RSV infection, in direct proportion to the exposure time to each virus. The use of a high concentration of recombinant hβD-2 resulted in less deleterious viral effect on the cells. The results suggest that both viruses induce hβD-2 production, no matter if the virus is enveloped or not, and that presence of hβD-2 reduces replication and cytopathic in vitro effect of RSV and ADV. The hβD-2 production by low pathogenicity viruses or live viral vaccines can be useful as therapeutic tools in some infectious diseases.
Social-psycho Issues of Enterprise Information System Usage among Government Outsource Vendors Comprising Malaysian Small-Medium Enterprises

This paper describes the socio-psychological issues that hinder the holistic usage of ERP system among sampled Malaysian SME’s that were the vendors through government outsourced projects. Five hundred questionnaires were sent to the pre-identified SMEs in Selangor through e-mail, 251 questionnaires were returned and only 110 were taken for data analysis, representing 44% of the response rate. The study found that the perceived benefits and social influence have positive significant relationship with the ERP system usage. The social influence has the strongest effect towards the ERP system usage among SMEs in Selangor. The system complexity does not influence the relationship between socio-psychological factors and ERP system usage among SMEs in Selangor. This study provides insight for the management of SMEs and the service providers on the factors influencing the ERP system usage. It contributes to the breadth of knowledge of the ERP system in SMEs from the perspective of a developing nation since the SMEs play an important role in the nation’s economy.
Cognitive and Affective Learning in the Basic Course: Effects of Delivery Format, Immediacy, and Communication Apprehension.

A quasi-experimental design was used to investigate changes in learning outcomes for students enrolled in large-lecture/break-out sections versus in self-contained sections of the basic communication course. More precisely, the study explores the relationship between communication apprehension, immediacy and learning outcomes for the two class formats. Results indicate that students' cognitive learning outcomes are slightly higher in the large-lecture/break-out sections versus self-contained sections. In addition, affective learning decreases for all students from the first day of class and slightly more for students in the large-lecture/break-out sections. However, when the teacher is perceived as highly immediate, there is no difference in formats. (Contains 5 notes, 55 references, 1 figure, and 5 tables and a figure of data; an appendix contains the cognitive learning measure items.)

Not-for-profit creative festivals face particular challenges with regard to practising knowledge transfer within a dynamic organizational context and short time frames for the production of cultural events

Purpose – Problem-solving approaches to research have dominated the not-for-profit festival management field. Little attention has been paid to how festival organizations successfully create cultures where knowledge transfer is practised within the high intensity of a festival lifecycle. Drawing upon insights from Social Practice Theory and Appreciative Inquiry (AI), our purpose in this article is to offer a different conceptual approach to understanding how knowledge transfer ‘works’ as an organizational practice to produce a collaborative festival culture. Design/methodology/approach This article draws upon an ethnographic case study with the highly acclaimed Queensland Music Festival organization in Australia. The research questions and methods were framed around an appreciative approach that identified formal and informal practices that ‘worked’ rather than a conventional problem focused analysis. Findings – Our research focused on appreciating the cultural context that shaped the interrelationships between formal and informal knowledge transfer practices that enabled trust and collaboration. We identified a range of knowledge transfer practices that contributed to the creation of a shared festival ethos and the on-going sustainability of the festival vision. Practical implications The not-for-profit sector brings numerous challenges for festival organizations and there is a need to appreciate how collaborative and creative knowledge transfer can occur formally and informally. Festival organizers can benefit from understanding the relational and practice dimensions of knowledge management as they are performed within specific organisational contexts. Originality/value – An appreciative understanding of knowledge transfer practices has not yet been applied to not-for-profit festival organizations where problem-solving approaches dominate the field.
