Instruction via Chat: Does Co-Browse Help?

Purpose: The purpose of this research is to determine whether instruction would be welcomed by Instant Messaging (IM)/chat users, whether instruction is possible in this medium, whether it can be effectively provided, and if the use of co-browsing enhances learning. Methodology: Two studies were conducted in which IM/chat reference transcripts were analyzed and patron surveys collected. This research paper compares results from these studies, the first based on use of text-only IM software, the second using commercial chat software with a co-browse feature. Findings: Findings indicate that patrons welcome instruction, whether they ask for it or not, and are satisfied with chat/IM as an instructional medium. Librarians usually provide instruction, though they are more likely to do so if patrons ask for it, directly or indirectly. Co-browsing was used little and did not increase the amount of instruction provided. Patron question format had an impact on the likelihood of co-browsing. Despite a high rate of technical difficulties, co-browsing was very well received by survey respondents. Practical implications: Findings suggest more training on the importance of instruction in virtual reference is needed. Originality/value: Providing instruction via reference is an established practice at the physical reference desk, yet few studies of instruction in virtual reference have been conducted and none on co-browsing as an instructional tool. This study addresses the
Rural Development Policy and Economic Benefits Diffusing to Neighbouring Rural-Urban Areas in Greece: An Interregional SAM Approach /доклад на 87 семинаре ЕААЕ, Assessing Rural Development Policies of the CAP, Vienna, Austria, 21-23 April 2004

This paper presents an analysis and evaluation of the impacts of rural development policies implemented in the rural town of Archanes, an area in Crete which has received considerable rural development funds during the CSF I and II. A hybrid interregional Social Accounting Matrix approach is used to describe interlinkages between Archanes and neighbouring rural and urban localities. Then, preliminary results are reported on the diffusion- patterns of rural development policy impacts in terms of generated output and income. Results show that policy-related economic benefits leak primarily to the ’affluent’ urban area of Heraklion and marginally to the less-developed rural area of N. Kazantzakis. Taking account of the significant rural development policy investment that has taken place in Archanes in recent years, this finding raises doubts on the contribution of these policies towards the core EU policy-objective of cohesion.
Esterase activity and detection of carboxylesterase and phosphotriesterase in female desert locust Schistocerca gregaria (Forskal) in relation to tissues and ages

General esterases activity in the different body tissues of adult females of 2-day and 13-day-old Schistocerca gregaria (Forskal) were measured spectrophotometricaly and carboxylesterase and phosphotriesterase were characterized by electrophoresis method. Esterase activities were studied in the tissues of brain, fore-, mid-, hindgut and ovary of the two ages in the presence of α-naphthyl acetate as a substrate and ethylenediamine tetraacetic acid (EDTA) and profenofos as inhibitors. Spectrophotometric analysis indicated that the esterase activity in adult S. gregaria tissues was significantly higher in the tissues of mid-, foregut, ovary and brain of 2day-old females than those of 13-day-old, respectively. Meanwhile, the activity was greater in the hindgut tissue of 13-day-old females than in 2-day-old ones. Nondenaturing polyacrylamide gel electrophoresis revealed differences in isozyme composition. Three to ten esterase bands were detected in the different body tissues of the two ages of adult females. These bands were characterized as phosphotriesterase and carboxylesterase by using the two inhibitors. Bands Est-1, Est-2, Est-3 and Est-6 were found to be carboxylesterase in the different tissues, while band Est-4 was only detected to be phosphotriesterase.
Use of magnetic separation for purifying quartz for luminescence dating

Introduction The increased use of the single aliquot regenerative (SAR) dose protocol and its current acceptance as the preferred protocol for dating quartz calls for efficient methods for purifying quartz. Common components of the sediment that need to be removed are salts, clays, carbonates, organic matter, heavy minerals and feldspars. Salts are usually water soluble; clays can be removed by sieving or decanting; carbonates are dissolved by 5-10% HCl; and organic matter is oxidized by concentrated peroxide or bleach.
Proximate Composition of Nile Tilapia (Oreochromis niloticus) (Linnaeus, 1758) and Tilapia Hybrid (Red Tilapia) from Oyan Lake, Nigeria

The aim of this study was to determine and compare the proximate composition of Oreochromis niloticus and hybrid Tilapia, from Oyan Lake. Â Parameters proximate composition which includes protein, lipid, ash and moisture content were estimated. The average moisture content for O.niloticus was in range of 81.11 to 81.67% and 80.01 to 80.17% for hybrid Tilapia. %. Results revealed that there was a significant difference in the mean protein values of O.niloticus and hybrid tilapia with the females of the two fish species were observed to have significantly higher (p <0.05) crude protein content than their male counterparts. The fat content values were low but significantly different (p<0.05) between the hybrid Tilapia and O.niloticus . Ash content ranged from 1.24 to1.48% for the O.niloticus and 1.30 to 1.24% for the hybrid Tilapia.
The Benefits of Double-Blind Review

So, I’m sure everyone here knows what double-blind review is, but nonetheless, I’m going to define it anyway just to make sure we’re all on the same page. Double-blind peer review is where the identities of a paper’s authors and reviewers are concealed from each other. This is in contrast to singleblind review, in which reviewer identities are concealed from authors but not vice versa, and open peer review, where neither the identities of authors or reviewers are concealed. The primary motivation behind doubleblind review is to eliminate bias in the reviewing process by preventing factors other than scientific quality from influencing the perceived merit of the work under review. At this point in time, double-blind review is the de facto standard for machine learning conferences.
Sensitivity to Imperfections of Perforated Pallet Rack Sections

The paper analyses the influence of imperfections on the behaviour of perforated pallet rack members in compression using non-linear FE simulations. The effect of imperfections, perforations and buckling modes, reduces significantly the capacity of perforated members in compression, especially in the coupling range due to interaction. A sensitivity analysis done using calibrated and validated numerical models can be done in order to determine the most detrimental combinations of imperfections to be considered for numerical simulations. The ECBL approach can be successfully applied to perform a sensitivity analysis via numerical simulations, using a limited number of experimental
Use of Distillers Dried Grains with Solubles (DDGS) as Replacement for Soybean Meal in Laying Hen Diets

An experiment was conduced to evaluate the inclusion of Distillers Dried Grains with Solubles (DDGS) in commercial layer diets with Avizyme 1500 supplementation. Two hundred eighty-eight 40-week- ® old Bovans brown layers were distributed in a completely randomized experimental design in a 2 x 4 factorial arrangement, with the variables being (DDGS) substitution for soybean meal at four levels (0 or 25% or 50% or 75%) and Avizyme 1500 at two levels (0 or 0.075%). Layer performance, egg quality, nutrients digestibility and blood parameters were evaluated. Results showed that average egg production, egg weight, egg mass, feed conversion ratio and the change in body weight of laying hens were significantly (p<0.05) decreased as dietary inclusion of DDGS increased. Avizyme supplementation relatively improved (p<0.05) egg production, egg mass and feed conversion ratio for DDGS inclusion levels at 25 and 50% when compared to those fed diets without Avizyme supplementation. No significant effect of DDGS, Avizyme, or thei r interaction on feed intake was observed. Yolk color was significantly increased, when DDGS was included in the diet. No significant differences in digestion coefficient values of Dry Matter (DM), Organic Matter (OM), Ether Extract (EE) and Nitrogen Free Extract (NFE) while, there were significant differences (p<0.05) for Crude Protein (CP) and Crude Fiber (CF) digestibility. Dietary inclusion of DDGS without Avizyme linearly reduced cost of feed. Although Avizyme supplementation increased the cost per kilogram of formulated diet, but improves economical efficiency value. The results suggest that diets containing DDGS at less than 15.45% level (50% of SBM) with Avizyme 1500 supplementation could improve the nutritive value of DDGS for layers. ®
Knowledge and Perception of Risks and Complications of Maternal Obesity during Pregnancy

The goal of this prospective survey study was to assess the knowledge and understanding of the risks of maternal obesity during pregnancy in patients visiting a prenatal Health Clinic at an academic, public medical center located in Macon, Georgia. Demographic information and questions about knowledge and perception of Body Mass Index (BMI) and maternal obesity risks were collected. Responses were scored between 0-100% and categorized to minimal, good and broad knowledge groups. The study population ranged in age from 18 to 69 years and 85.3% of the study participants were African American and 12.7% Caucasian. Most respondents have moderately good knowledge of maternal obesity risk. However, only 40.2% of women were aware of the term BMI, 48% knew goals of weight gain during pregnancy, and 51% were aware that obesity increases the risk of stillbirth. Obese patients were more aware of the risk for pregnancy complications compared to normal and overweight. But only 29.7% of them correctly identified themselves as obese, 53.1% classify themselves as overweight, 15.6% normal and 1.6% report being underweight. Maternal weight, educational status and daily exercise were consistently associated with good and broad knowledge of maternal risks. Overall, most women have limited knowledge of BMI, goals of weight gain during pregnancy and risks of maternal obesity on them and their unborn child. The perception of most overweight and obese women about their current weight was imprecise. Our findings underscore the need for healthcare providers to make pregnant women more aware of the increased risks associated with overweight and obesity.
SOIL STABILIZATION USING LIME

Soil stabilization can be explained as the alteration of the soil properties by chemical or physical means in order to enhance the engineering quality of the soil . The main objectives of the soil stabilization is to increase the bearing capacity of the soil ,its resistance to weathering process and soil permeability. The long-term performance of any construction project depends on the soundness of the underlying soils. Unstable soils can create significant problems for pavements or structures, Therefore soil stabilization techniques are necessary to ensure the good stability of soil so that it can successfully sustain the load of the superstructure especially in case of soil which are highly active, also it saves a lot of time and millions of money when compared to the method of cutting out and replacing the unstable soil. This paper deals with the complete analysis of the improvement of soil properties and its stabilization using lime.
Carbon regulation and pathways for institutional transition in market-led housing systems: A case study of English housebuilders and zero carbon housing policy

In this paper, we argue that current research on carbon regulation neglects the complex interactions of institutional norms and market behaviour that characterise responses to regulatory change. We draw on empirical research undertaken with English housebuilders and housing market stakeholders to examine how transitional pathways towards a low-carbon housing future might be advanced and consider the implications of such for carbon regulation and low-carbon economies. Our core proposition is that carbon regulation research can no longer ignore the impact of institutionally constituted market behaviour in shaping pathways and transitions towards low-carbon futures.
On Interactions of Optimal Climate Policy and International Trade. An Assessment of Border Carbon Measures.

Not only after the failure of the Copenhagen climate conference 2009, border carbon adjustment (BCA) has received growing attention in the climate policy debate as a measure to combat "carbon leakage" and force non-abating countries to tighter climate policies. In this paper, we study the strategic interactions between international trade and climate policy with a focus on the effectiveness of border measures. First, we analyze the main principles of unilateral climate policy with international trade in a small analytical model. Second, we examine welfare effects of WTO compatible carbon import tariffs in a stylized numerical integrated assessment model with explicit trade in commodities and analyze if BCA is a credible threat to force non-abating countries to implement stricter climate policies. We show that the terms of trade effects can, depending on trade patterns, ease or boost the prisoners dilemma of mitigating greenhouse gases. We further demonstrate that WTO conform BCA increases the effectiveness of climate policy and forces trading partners to reduce emissions. But as the results of the numerical model illustrate, welfare effects are depended on trade flows and are negative for realistic parameter values.
MODELING THE EFFECT OF VARIATION IN SAGITTAL CURVATURE ON THE FORCE REQUIRED TO PRODUCE A FOLLOWER LOAD IN THE LUMBAR SPINE

The aim of this study was to investigate how the forces required to stabilize the lumbar spine in the standing posture may be affected by variation in its shape. A two-dimensional model of the lumbar spine in the sagittal plane was developed that included a simplified representation of the lumbar extensor muscles. The shape of the model was varied by changing both the magnitude and distribution of the lumbar curvature. The forces required to produce a resultant load traveling along a path as close to the vertebral body centroids as possible (a follower load) were determined. In general,the forces required to produce a follower load increased as the curvature became larger and more evenly distributed. The results suggest that the requirements of the lumbar muscles to maintain spinal stability in vivo will vary between individuals. This has implications for understanding the role of spinal curvature and muscle atrophy in back pain.
Analyses of Full-Scale Tank Car Shell Impact Tests

This paper describes analyses of a railroad tank car impacted at its side by a ram car with a rigid punch. This generalized collision, referred to as a shell impact, is examined using nonlinear finite element analysis (FEA) and threedimensional (3-D) collision dynamics modeling. Moreover, the analysis results are compared to full-scale test data to validate the models. Commercial software packages are used to carry out the nonlinear FEA (ABAQUS and LS-DYNA) and the 3-D collision dynamics analysis (ADAMS). Model results from the two finite element codes are compared to verify the analysis methodology. Results from static, nonlinear FEA are compared to closed-form solutions based on rigid-plastic collapse for additional verification of the analysis. Results from dynamic, nonlinear FEA are compared to data obtained from full-scale tests to validate the analysis. The collision dynamics model is calibrated using test data. While the nonlinear FEA requires high computational times, the collision dynamics model calculates gross behavior of the colliding cars in times that are several orders of magnitude less than the FEA models.
When good news is bad news: the negative impact of positive customer feedback on front-line employee well-being

Purpose – Front-line employee (FLE) well-being is an under-researched field. Contrasting the prevailing view that Positive Customer Feedback (PCF) can only have ‘positive’ impacts, this study aims to answer the counterintuitive question: Could the apparently positive construct ‘Positive Customer Feedback’ have a negative impact on the well-being of front-line employees? Consequently, working within the Transformative Service Research (TSR) framework, we investigate whether PCF can negatively affect the eudaimonic and hedonic well-being dimensions of FLEs, thus decreasing their overall psychological well-being level. Design/methodology/approach – A multidisciplinary literature review was conducted, particularly in the social psychology, human resources and organizational behavior fields, to examine the potential negative impacts of PCF. Subsequently, an exploratory qualitative study consisting of seven focus groups with 45 FLEs and 22 in-depth interviews with managers working across various service industr.
An Investigation of Comparative Advantage of Pistachio Production and Exports in Iran

Pistachio is a major agricultural export commodity in Iran. Nowadays, it ranks first among Iran’s agricultural exports. This paper focuses on the comparative advantage in pistachio production and the export market in Iran. A policy analysis matrix (PAM) framework and revealed comparative advantage (RCA) index are applied to 2000-2004 data to study Iranian government policy regarding pistachio production and export. In addition, the producer protection indices in the framework of the aforementioned matrix was calculated in order to study input and output protection policy. Results showed that Iran has a comparative advantage both in the production and export of this commodity, but the comparative advantage in pistachio production is diminishing. The RCA index showed that the comparative advantage of pistachio exports from Iran has progressed. Indices showed a high net social profitability and government protection of pistachio producers in terms of input subsidies. Then, the effects of the changing world price, exchange rate, cost of domestic factors, and cost of tradable inputs on the comparative advantage and protection indices showed that, for retaining comparative advantage in pistachio production, productivity and production costs must be both increased and decreased, respectively. In order to increase the productivity of pistachio, farmers should use scientific on-farm management and should employ modern production methods, and the government should develop research and development institutes.
The JCMT Legacy Survey of the Gould Belt: a first look at Serpens with HARP: GBS: first look at Serpens

The Gould Belt Legacy Survey will survey nearby star-forming regions (within 500 pc), using HARP (Heterodyne Array Receiver Programme), SCUBA-2 (Submillimetre Common- User Bolometer Array 2) and POL-2 (Polarimeter 2) on the James Clerk Maxwell Telescope (JCMT). This paper describes the initial data obtained using HARP to observe 12CO, 13CO and C18O J = 3 - 2 towards two regions in Orion B, NGC 2024 and NGC 2071. We describe the physical characteristics of the two clouds, calculating temperatures and opacities utilizing all three isotopologues. We find good agreement between temperatures calculated from CO and from dust emission in the dense, energetic regions. We determine the mass and energetics of the clouds, and of the high-velocity material seen in 12CO emission, and compare the relative energetics of the high- and low-velocity material in the two clouds. We present a CLUMPFIND analysis of the 13CO condensations. The slope of the condensation mass functions, at the high-mass ends, is similar to the slope of the initial mass function.
XManDroid: A New Android Evolution to Mitigate Privilege Escalation Attacks

Google Android has become a popular mobile operating system which is increasingly deployed by mobile device manufactures for various platforms. Recent attacks show that Android's permission framework is vulnerable to application-level privilege escalation attacks, i.e., an application may indirectly gain privileges to perform unauthorized actions. The existing proposals for security extensions to Android's middleware (e.g., Kirin, Saint or TaintDroid) cannot fully and adequately mitigate these attacks or detect Trojans such as Soundminer that exploit covert channels in the Android system. In this paper we present the design and implementation of XManDroid (eXtended Monitoring on Android), a security framework that extends the monitoring mechanism of Android to detect and prevent application-level privilege escalation attacks at runtime based on a system-centric system policy. Our implementation dynamically analyzes applications' transitive permission usage while inducing a minimal performance overhead unnoticeable for the user. Depending on system policy our system representation allows for an effective detection of (covert) channels established through the Android system services and content providers while simultaneously optimizing the rate of false positives. We evaluate the effectiveness of XManDroid on our test suite that simulates known application-level privilege escalation attacks (including Soundminer), and demonstrate successful detection of attacks that use Android's inter-component communication (ICC) framework (standard for most attacks). We also preformed a usability test to evaluate the impact of XManDroid on the user-experience with third party applications. Moreover, we analyze sources of false positives and discuss how this rate can be further significantly reduced.
Effect of formaldehyde vapor on the blood constituents of male rabbits

The present experimental study was designed to investigate the effect of formaldehyde on blood constituents of rabbit males, Twenty four adult males were randomly subdivided into 3 groups (I, II, III) and exposed to vapour of 10% FD (12 ppm) in cages for the following periods: 2, 4 and 6 months; beside, 8 rabbits were exposed to vapour of distilled water as a control group. Blood parameters examination showed no morphological changes, but with a significant increase in lymphocytes and esonophils percentage. Significant decrease in neutrophil, red blood cell (RBC) and platelets counts was detected. The present study concluded that formaldehyde of such concentration and exposure time have an effect on blood constituents of rabbit males.
