Tenured Teachers & Technology Integration In The Classroom

This article explores teachers’ technology integration in the classroom through 2 means: 1) what researchers are saying about emerging trends and best practices as well as, 2) the author’s research assignment regarding the technology integration experiences of longer tenured teachers. More tenured teachers are different than their younger colleague in that they did not receive the same quantity of preservice technology integration instruction as part of their teacher education as their younger counterparts. Four priorities that emerged for educational stakeholders to consider in order to help transition educators from technology operators to technology facilitators and integrators (Gorder, 2008) are: 1) planning for technology, 2) addressing teacher concerns, 3) understanding and addressing the technological ability differences amongst staff, and 4) comentorship and collaboration.
Financial reporting quality, ownership concentration, and investment efficiency: evidence from China

This paper uses 3,726 samples of Chinese listed firms during the period 2008–2012 to examine the relation between financial reporting quality, ownership concentration, and investment efficiency. We find that financial reporting quality is negatively associated with both underinvestment and overinvestment. Further, financial reporting quality is more strongly associated with overinvestment for firms with low ownership concentration, which suggests that financial reporting quality can reduce information asymmetry between the managers and investors and thus lower shareholders’ cost of monitoring managers and improving project selection. Our findings contribute to the literature on financial reporting and investment in emerging capital markets.
Sulfur dioxide effects on yield and seed quality in field-grown soybeans.

Field plots of soybeans were periodically exposed to elevated levels of sulfur dioxide with an open-air fumigation system which minimized disruption of the normal crop environment. Although visible injury was observed in only two plots, yield at harvest was reduced in every fumigated plot compared to nearby unfumigated control plots. These yield decreases ranged from 5% to 48% and were somewhat greater than might have been expected from previous studies. Yield reductions seemed to be due to decreases in both the mean weight per seed and the number of seeds per plant. Seed quality was affected less than seed yield, although at the higher exposure levels protein content decreased slightly and concentrations of some mineral elements were altered.
ON THE SPECTRUM OF ENERGY IN TURBULENT SHEAR FLOW

A turbulent flow with a given spatial pattern of mean motion invariant with time is treated. No solid boundary is considered. By means of the Fourier analysis of the NavierStokes equation, it is possible to obtain an equfl,tion of energy balance in spectral terms. T his involves the following functions: Viscous dissipation, transfer, production, convect.ion, and diffmion. The first two functions are common to the isotropic and homogeneous turbulence without mean motion. Assuming that eddies controlled by inhomogeneity are much larger than those controlled by anisotropy, stationary spectral laws are obtained for small eddies in the viscous and non viscous ranges. The agreement between theory and experiment is shown.
Structure-preserving finite difference scheme for vortex filament motion

Finite di®erence scheme for the model equation of vortex filament in three dimensional fluid is proposed. We show that the scheme inherits length-preserving and energy structures from the original model. We also show that solvability of the scheme since the scheme is implicit and nonlinear and give an error estimate of the iteration. Finally, numerical results are shown.
A Combination of Time Domain Finite Element-Boundary Integral and with Time Domain Physical Optics for Calculation of Electromagnetic Scattering of 3-D Structures

This paper presents a hybrid numerical approach combining an improved Time Domain Finite Element-Boundary Integral (FE-BI) method with Time Domain Physical Optics (TDPO) for calculations of electromagnetic scattering of 3-D combinative- complex objects. For complex-combined objects containing a small size and large size parts, using TDPO is an appropriate approach for coupling between two regions. Therefore, our technique calculates the objects complexity with the help of FE-BI and the combinatory structures by using of the TDPO. The hybridization algorithm for restrictive object is implemented and the numerical results validate the superiority of the proposed algorithm via realistic electromagnetic applications.
Practical x-ray ghost imaging with synchrotron light

We present a practical experimental realization of transmission x-ray ghost imaging using synchrotron light. Hard x-rays from an undulator were split by a Si 200 crystal in Laue geometry to produce two copies of a speckled incident beam. Both speckle beams were simultaneously measured on a CCD camera. The sample was inserted in one of the two beams, and the corresponding image was integrated over the camera extent to synthesize a bucket signal. We show the successful x-ray ghost image reconstruction of two samples and discuss different reconstruction strategies. We also demonstrate a method for measuring the point spread function of a ghost imaging system, which can be used to quantify the resolution of the ghost imaging reconstructions and quantitatively compare different reconstruction approaches. Our experimental results are discussed in view of future practical applications of x-ray ghost imaging, including a means for parallel ghost imaging.
The Metaverse: Telepresence in 3D Avatar-Driven Digital-Virtual Worlds

This paper provides a reflection about the concepts of presence and telepresence in the use of emergent Digital-Virtual Technologies (DVTs), particularly concerning 3D Digital-Virtual Worlds - 3D-DVWs. It reports on the experience of tele presence driven by avatars designed to be used in 3D-DVWs processes.
Antibacterial activity of endophytic fungi extracts from the medicinal plant Kigelia africana.

The aim of this study was to identify the endophytic fungi of the medicinal plant Kigelia africana (Lam) Benth. (Bignoniaceae) and to investigate their potential antimicrobial activity. Seven species of endophytic fungi were successfully isolated from K. Africana for the first time: including Cladosporium sp. , Aspergillus flavus, Aspergillus sp. , Curvularia lunata as well as three unknown species. The fungal extracts were assessed for antibacterial activity against three standard pathogenic bacterial strains: Bacillus subtilis, Staphylococcus aureus and Escherichia coli. Most of the extracts showed in vitro inhibition of bacterial growth. The phytochemical screening revealed the existence of a diverse group of secondary metabolites in the crude extracts of the endophytic fungi that resemble those in the host plant extracts.
Absolute dimensions of detached eclipsing binaries – III. The metallic-lined system YZ Cassiopeiae

The bright binary system YZ Cassiopeiae is a remarkable laboratory for studying the Am phenomenon. It consists of a metallic-lined A2 star and an F2 dwarf on a circular orbit, which undergo total and annular eclipses. We present an analysis of 15 published light curves and 42 new high-qualityspectra, resulting in measurements of the masses, radii, effective temperatures and photospheric chemical abundances of the two stars. The masses and radii are measured to 0.5 per cent precision: MA = 2.263 ± 0.012 M� , MB = 1.325 ± 0.007 M� , RA = 2.525 ± 0.011 Rand RB = 1.331 ± 0.006 R� . We determine the abundance of 20 elements for the primary star, of which all except scandium are supersolar by up to 1 dex. The temperature of this star (9520 ± 120 K) makes it one of the hottest Am stars. We also measure the abundances of 25 elements for its companion (Teff = 6880 ± 240 K), finding all to be solar or slightly above solar. The photospheric abundances of the secondary star should be representative of the bulk composition of both stars. Theoretical stellar evolutionary models are unable to match these properties: the masses, radii and temperatures imply a half-solar chemical composition (Z = 0.009 ± 0.003) and an age of 490-550 Myr. YZ Cas therefore presents a challenge to stellar evolutionary theory.
Influence of Body Condition Score on Yield and Composition of Milk in Crossbred Dairy Cows

The study was carried out for a period of 150 days on 120 Holstein Friesian crossbred dairy cows between mid to late lactation to quantify the influence of body condition score (BCS) on yield and composition of milk. Total 12 dairy farms having same housing systems and holding at least 20 crossbred dairy cows per farm between mid to late lactation were selected for this study purposes. BCS of individual cows was recorded in a 1-5 scale. Milk samples were collected from individual cow. Samples collected from cows having same BCS were mixed together to make composite sample. Chemical analyses of the samples were carried out in triplicate for fat, protein, lactose, ash, total solids (TS) and solids not fat (SNF). Results indicated that, BCS significantly (P 0.05) with increasing BCS up to 4.0. Correlation coefficient matrix indicated that BCS was negatively correlated with milk yield. However, there was a positive relationship of BCS with milk protein, lactose, TS, SNF and SG even though the strength of association was variable.
Numerous asymptomatic dermal cysts: Diagnosis and treatment of steatocystoma multiplex.

OBJECTIVE To provide family physicians with the information needed to recognize, diagnose, and discuss available treatment options for steatocystoma multiplex (SM). SOURCES OF INFORMATION A comprehensive PubMed search using steatocystoma multiplex as either a text word or a MeSH term was conducted, and articles reporting on treatment outcomes were included. MAIN MESSAGE Steatocystoma multiplex is a benign disorder often characterized by numerous asymptomatic dermal cysts on the trunk, arms, axillae, face, thighs, and scalp. Psychological distress due to these undesirable lesions is not uncommon for this condition. A literature review identified the following SM treatments, all of which were associated with limitations: carbon dioxide laser, modified surgical techniques, cryotherapy, and medical management. Steatocystoma multiplex is challenging to treat and, at this time, effective management is most often achieved through patient education. CONCLUSION Family physicians play a critical role in the early diagnosis and management of SM. Education about treatment options and managing patient expectations might greatly alleviate the psychosocial implications of this disease.
Compliance to Corporate Governance Code by Listed Companies in Egypt and the UAE

The purpose of this study is to examine in some depth the extent to which national corporate governance code (CG) is followed by companies listed in Egyptian Securities Exchange (EGX) and by Securities Exchange in United Arab Emirates (UAE) both in terms of adoption and reporting. Although there is a growing acknowledgment of the importance of corporate governance all over the world and in the Middle East, the region is rarely examined in the literature or introduced or linked with the international academic arena. Data for this paper was collected from the listed companies in securities exchange of the two countries at the end of 2010. Annual reports and websites and other sources of these companies were checked. Results show more compliance to CG code by UAE companies comparing to Egyptian companies and with more reporting as well. The overall compliance in Egypt was associated with more diversity in industry and to a less degree with having foreign operations while in UAE the compliance was led by banks and financial sector which is tightly regulated from the central bank and even stronger association with having foreign operations. Ownership has no significant influence on compliance to national code of corporate governance in both countries.
NEW SPECIES OF THE GENUS CHONDROSTOMA AGASSIZ, 1832 (ACTYNOPTERIGII, CYPRINIDAE) FROM WESTERN PORTUGAL

A new cyprinid species endemic to western Portugal, Chondrostoma occidentale sp. n. , is described based on fish collected in the small costal drainages of the Rivers Alcabrichel, Sizandro and Safarujo. The new species belongs to a monophyletic clade that also includes C. oligolepis and C. arcasii, with which it shares many molecular and morphological features. However, it can be distinguished from these two Chondrostoma species by a combination of the following characters: 40-43 ( = 40.9) canaliculate scales on the lateral line; 6-7 ( = 6.9) above the lateral line; 2-3 ( = 2.9) scales below the lateral line. The axilary pelvic scale is smaller than or at most equal to the base of the pelvic fin. The coronoid process of the dentary is very thick. The minimum divergence distances in cytochrome b between C. occidentale and C. oligolepis and C. arcasii was “p” = 4.8-5.9%. This new species should be considered Critically Endangered (CR) according to the IUCN Red List Categories.
Event-Driven Duplicate Detection: A Probability-based Approach

The importance of probability-based approaches for duplicate detection has been recognized in both research and practice. However, existing approaches do not aim to consider the underlying real-world events resulting in duplicates (e.g., that a relocation may lead to the storage of two records for the same customer, once before and after the relocation). Duplicates resulting from real-world events exhibit specific characteristics. For instance, duplicates resulting from relocations tend to have significantly different attribute values for all address-related attributes. Hence, existing approaches focusing on high similarity with respect to attribute values are hardly able to identify possible duplicates resulting from such real-world events. To address this issue, we propose an approach for event-driven duplicate de-tection based on probability theory. Our approach assigns the probability of being a duplicate resulting from real-world events to each analysed pair of records while avoiding limiting assumptions (of existing approaches). We demonstrate the practical applicability and effectiveness of our approach in a real-world setting by analysing customer master data of a German insurer. The evaluation shows that the results provided by the approach are reliable and useful for decision support and can outperform well-known state-of-the-art approaches for duplicate detection.
Digital literacy: The quest of an inclusive definition

Forces of globalisation and economic competition enhanced by, among others, the digital technologies, are radically transforming the social context. Digital technologies are characterised by a powerful and pervasive Internet as well as the related information and communication technologies. Globalisation is facilitated by the universally accessible, reliable and inexpensive communication assisted by these digital technologies. However, there is growing and valid scepticism regarding the digitally influenced socio-economic emancipation. This scepticism is mainly driven by a lack of understanding of digital literacy as a holistic process of creating the necessary social, economic and political changes within a given context. The understanding of digital literacy therefore needs to join a number of seemingly divergent views of digital technology when dealing with these technologies’ benefits in socio-economic emancipation. This understanding of digital literacy should therefore be shaped and focused more on understanding how digital literacy impacts the poor and marginalised, especially in looking at the socio-economic welfare of these marginalised sections of the society. This article discusses digital literacy by firstly looking at the shortcomings of the available definitions and approaches and then recommends a socio-economic development-orientated definition. The article brings to the fore the most critical digital literacy issues for socio-economic development. These issues are important; they ensure that digital literacy is not viewed in isolation, but rather in terms of its outcomes and consequences, especially with regard to socio-economic development.
The changing landscape of ePortfolios: A case study in one Australian university

The potential of ePortfolios for both students and staff has generated considerable interest and investment by universities over the past ten years or so within Australia. Despite funded projects, ePortfolio specific conferences and a range of commercial and open software, there is not wide spread uptake of ePortfolios, although many universities continue to try and test a range of different options. This paper reports upon the experience of an Australian university when considering implementation and uptake of ePortfolio technology between 2008 and 2011. It describes the technological and sectoral factors that have to some extent shaped Australian ePortfolio context and affected the institutional ePortfolio initiative at Griffith University.
Security system for passive IP devices on SIP based network

Passive IP devices like SIP based surveillance camera, need to be secured due to the private information that it may transmit. This paper proposes an architecture to secure the information that the device could access in peer-to-peer overlay networks. This architecture provides the security mechanism for authentication, authorization and audit (AAA). It combines the security features of Authentication Servers with SIP architecture to provide AAA Service to registered users needing access to passive IP devices. Dynamic password for authenticating the access of the passive devices managed by the authentication server could be also applied to enhance the security features of devices.
Community climate simulations to assess avoided impacts in 1.5 and 2 °C futures

Abstract. The Paris Agreement of December 2015 stated a goal to pursue efforts to keep global temperatures below 1.5 °C above preindustrial levels and well below 2 °C. The IPCC was charged with assessing climate impacts at these temperature levels, but fully coupled equilibrium climate simulations do not currently exist to inform such assessments. In this study, we produce a set of scenarios using a simple model designed to achieve long-term 1.5 and 2 °C temperatures in a stable climate. These scenarios are then used to produce century-scale ensemble simulations using the Community Earth System Model, providing impact-relevant long-term climate data for stabilization pathways at 1.5 and 2 °C levels and an overshoot 1.5 °C case, which are realized (for the 21st century) in the coupled model and are freely available to the community. Here we describe the design of the simulations and a brief overview of their impact-relevant climate response. Exceedance of historical record temperature occurs with 60 % greater frequency in the 2 °C climate than in a 1.5 °C climate aggregated globally, and with twice the frequency in equatorial and arid regions. Extreme precipitation intensity is statistically significantly higher in a 2.0 °C climate than a 1.5 °C climate in some specific regions (but not all). The model exhibits large differences in the Arctic, which is ice-free with a frequency of 1 in 3 years in the 2.0 °C scenario, and 1 in 40 years in the 1.5 °C scenario. Significance of impact differences with respect to multi-model variability is not assessed.
Genetic Differentiation of Carassius auratus and C. cuvieri by the Cytochrome C Oxidase I Gene Analysis

It is estimated that 27 bony fish species have been introduced into Korean freshwaters for aquaculture and the enhancement of fishery resources. Among them, Carassius cuvieri has completely adapted and is widely distributed throughout Korean freshwater ecosystems. In this study we investigated the genetic relationship between C. cuvieri and the closely related native crucian carp species Carassius auratus. Nucleotide sequence variation within the mtDNA cytochrome c oxidase I (COI) gene was used to study the genetic divergence and phylogenetic relationships among the species and to identify their taxonomic status in the family Cyprinidae. We compared partial COI gene sequences (630 base pairs) from three populations of C. auratus and three populations of C. cuvieri. A total of 46 variable sites were identified from 163 individuals, yielding 23 haplotypes. The two species showed very close genetic relationship with 95% sequence identity in the COI gene, the frequency and distribution of haplotypes showed clear separation, suggesting divergent evolution of these two species. Therefore, despite the morphological similarity and phylogenetic closeness, the populations of these two species should be regarded as separate management units in the ongoing recovery program.
Investigation of Patients with Hippocampal Sclerosis Associated with Unusual Epileptic Activities

Ad dress for Cor res pon den ce/Ya z›fl ma Ad re si: Ebru Nur Vanlı Yavuz MD, İstanbul University İstanbul Faculty of Medicine, Department of Neurology, Division of Clinical Neurophysiology, İstanbul, Turkey Phone: +90 212 414 20 00 E-mail: ebruvanli@hotmail.com Re cei ved/Ge lifl Ta ri hi: 23.11. 2015 Ac cep ted/Ka bul Ta ri hi: 17.01. 2016 Objective: Hippocampal sclerosis (HS) is usually associated with typical anterior temporal spikes/sharp waves in the electroencephalography (EEG). We aimed to investigate the clinical, electrophysiologic differences, and prognosis between HS patients with unusual epileptic foci in comparison with patients with typical foci. Materials and Methods: Patients diagnosed who were diagnosed as having mesial temporal lobe epilepsy with HS in our center were included. All magnetic resonance imaging (MRI) results were investigated for the presence of two major criteria of HS diagnosis, namely T1 atrophy and T2 hyperintensity. All EEG and video-EEG investigations (a total of 496) were re-evaluated for unusual epileptic activities except T1/2, F7/8, T3/4 foci. Clinical and other laboratory data were retrospectively reevaluated by two investigators and the groups with usual and unusual epileptic activities for this syndrome were statistically compared. Results: A total of 124 patients including 20 (16.1%) with unusual epileptic activities (group 1) and 104 patients with typical foci (group 2) were evaluated. We observed 11 posterior temporal (T5/T6), four frontal (F3/F4), four frontopolar (Fp1/2), two occipital (O1/O2), three central (CP/FC) unusual foci, and two generalized epileptiform discharges in these 20 patients. Impaired background activity, nonspecific interictal diffuse slowing, and atypical seizure offset patterns were more frequently observed in group 1. Forty-nine patients underwent surgery after appropriate preoperative diagnostics; there was no significant difference in the postoperative outcome between the groups despite a tendency to better prognosis in group 2. Conclusion: Our study showed that unusual epileptic foci could be seen in 16.1% of patients with HS. Although some patients with HS have these atypical interictal EEG findings, they might obtain good post-operative outcomes when preoperative diagnostics are appropriately planned.
