Two Faces of Collaboration: A Critical Perspective on Effects of Collaboration in Learners' Corpus Consultation

Collaborative learning has been increasingly incorporated into learners' corpus consultation as a type of pedagogic mediation. However, studies found that collaborative learning has negative aspects as it may cause conflicts and power inequality among members. Given the two sides of collaboration, this study provides a critical investigation on the functions of collaboration in learners' corpus consultation. Through two collaborative corpus analysis sessions, three students of different L2 proficiency levels assisted each other’s understanding of corpus data to complete group activities. The students’ verbal and nonverbal behaviors during corpus analysis became the main source of investigation, complemented by the results of pre-/post-interviews and the researcher's direct observations. The findings of this study suggest that collaboration creates significant power inequality among the participants by gradually marginalizing the less capable student in the group from the learning process and increasing the psychological burden for the most capable student. In addition, collaborative work during corpus consultation could impede critical learning opportunities for individual students to pursue personal queries during collaboration. Despite some limitations, the findings of this study provide a realistic picture of collaboration in learners’ corpus consultation and suggest pedagogical implications to corpus-based instruction.
Application Of Extented Technology Acceptance Model In Predicting E-Procurement Utilization In Independent Commissions In Kenya

E-procurement has recently been introduced in the Kenyan public sector due to the many practical advantages it brings. Usage of the system is still at a very nascent stage. This paper sought to predict e-procurement utilization by analyzing the constructs of the Extended Technology Acceptance Model. The study administered a questionnaire to 229 employees of the 11independent commissions in the country. Regression analysis was done to describe the significance and the strength of relationships between variables. The analysis yielded important findings that partially support research hypotheses. The results indicated that subjective norm and reliability of the system influence utilization of the system while compatibility was insignificant. All the identified elements have correlations with the model elements and in turn impact on the behavioral intention to use the system. This study would influence government technology plans through implementation of policies that enhance adoption of emerging technologies in the public sector.
CONTACT STIFFNESS OF BODIES WITH FRACTAL ROUGHNESS: COMPARISON OF 3D BEM RESULTS AND REDUCTION METHOD

Using the linear elastic Boundary Element Method, we calculated the normal con- tact stiffness of fractal rough surfaces by means of the differential quotient of normal force and indentation and found a power-law dependence on the applied load. Exponents vary from 0.5 to 0.85 depending on the fractal dimension in contrast to Persson's theory, which predicts a linear dependency. For very high forces, saturation is reached, corresponding to full mate- rial contact of an equivalent smooth indenter. Efficient algorithms allowed for statistical evaluation after just a few days of calculation with grid sizes of 2049x2049 on a standard PC. The fractal behavior of the surface roughness was applied all the way from the sample size down to the shortest wavelength that could be represented on the chosen grid. The same cases were investigated using a reduction method proposed by one of the authors, which maps the 3D-contact onto a 1D-rough line having the same mechanical properties. Results were obtained with dramatically less investments in CPU time. As this approach al- lows for a much higher resolution up to 2^23, we found the power law to be valid in the as- ymptotic behavior for small normal forces, given that the surface has fractal-like roughness in the corresponding small length scales.
Conceptualizing the impact of perceived organizational support and psychological contract fulfillment of employees paradoxical intentions of stay and leave

The article presents a comprehensive and detailed conceptual framework on the effects of employees’ perceived organizational support on their paradoxical intentions of leaving to and staying with the organization in Psychological Contract Perspective. This study anticipates proposing an applicable technique to examine empirically the interrelationships of employees’ perceived organizational support, psychological contract fulfillment, intention to stay and intention to leave. This paper proposes theory-based path model, and possible interrelationships of related constructs such that the future analysis would be based on related statistical methods may include structural equation modeling approach. Although numerous researchers have studied the broad topics of perceived organizational support and employees’ turnover intentions, none of those studies has explored the paradoxical and differential impact of perceived organizational support on the intentions of staying and leaving. The innovative propositions using psychological contract fulfillment lenses in the relationship of perceived organizational support with the intention to stay and intention to leave, as explained by psychological contract perspective of social exchange theory would be the originality of this paper and possible contribution to the body of knowledge.

Parent-child Relationship and Filial Piety Affect Parental Health and Well-being

The purpose of this study is to examine the effects of parent-child relationship, filial piety and adult children's concept of family on the health and well-being of their parents. Data were obtained from the Panel Study of Family Dynamics in Taiwan, 2005-2011. The sample comprised parents with repeated measures and one wave data from their adult children (208 persons with 1,336 observations). The parent-child relationship predicted self-rated health for both fathers and mothers and predicted the life satisfaction of mothers. Filial piety was positively related to self-rated health of mothers but was negatively related to self-rate health of fathers.
The description and validation of the computationally Efficient CH 4 –CO–OH (ECCOHv1.01) chemistry module for 3-D model applications

Abstract. We present the Efficient CH4–CO–OH (ECCOH) chemistry module that allows for the simulation of the methane, carbon monoxide, and hydroxyl radical (CH4–CO–OH) system, within a chemistry climate model, carbon cycle model, or Earth system model. The computational efficiency of the module allows many multi-decadal sensitivity simulations of the CH4–CO–OH system, which primarily determines the global atmospheric oxidizing capacity. This capability is important for capturing the nonlinear feedbacks of the CH4–CO–OH system and understanding the perturbations to methane, CO, and OH, and the concomitant impacts on climate. We implemented the ECCOH chemistry module in the NASA GEOS-5 atmospheric global circulation model (AGCM), performed multiple sensitivity simulations of the CH4–CO–OH system over 2 decades, and evaluated the model output with surface and satellite data sets of methane and CO. The favorable comparison of output from the ECCOH chemistry module (as configured in the GEOS-5 AGCM) with observations demonstrates the fidelity of the module for use in scientific research.
Design of High-speed Dynamic Packet Filtering Firewall for IPv6 based on FPGA

Network security issues are becoming increasingly acute. A computer network exposed to the Internet without any security protection is at great risk. This paper proposes the packet filtering firewalls system based on FPGA. This system connects the high-speed firewall filtering module and the CPU (OR1200). The Internet Protocol Version 6 (IPv6) network data package is sent to test successfully by the PC client. Experimental results show that the system process the whole IPv6 data packet with 920ns and the complete design uses a small portion of the Altera StratixII/ EP2S60F672C5 FPGA, 25% of the logic blocks and 11% of the memory blocks. So the system not only has ideal functionality but greatly improves the data transmission speed
A mathematical model of the commercial harvest of Palmaria palmata (Palmariales, Rhodophyta) on Digby Neck, Nova Scotia, Canada

A mathematical model of the commercial harvest of Palmaria palmata (Dulse) is presented based on a logistic model and field data collected on Digby Neck, Nova Scotia from 14 harvested shores during May to August, 2010. Field observations used to estimate model parameters included cover of Dulse before and after harvest from Dulse dominated boulders for which surface area was estimated, and from which fresh biomass of harvested Dulse was weighed. Over all the surveys the average harvest fraction was about 50%, and the total resource was about . With growth rates in excess of 4% per day and a 50% harvest of the standing crop each month, the model suggests that the Dulse resource is sustainable at current harvest levels.
Views of Students, Parents, and Teachers on Homework in Elementary School.

The current study seeks to examine the perception of the three main populations that have a part in the educational and pedagogic domain: teachers, parents, and elementary school students, while comparing between religious and secular schools. The major hypothesis of the study is that teachers, parents, and students do not have congruent views on the aims and effectiveness of homework. Another hypothesis was that differences would be found between parents’ views of homework by religiosity. In addition, a negative association will be found between the teacher’s years on the job and attitude towards homework assignment–such that the more years of experience the more negative their attitudes towards homework assignment. Finally, differences will be found in the respondents’ views on homework assignment by the school’s geographic location. The research findings show that the first hypothesis was partially confirmed. Teachers are the most positive about homework, followed by students and finally parents. The confirmation was only partial, as the hypothesis was that students’ views would be the least supportive. The second hypothesis was not confirmed, as no significant differences were found between the views of religious and secular parents on homework. The findings concerning the third hypothesis found a significant negative correlation; such that the more experienced the teacher the more negative his or her attitude to homework, confirming the hypothesis. The conclusions of this study indicate that the homework format is in dispute and there is no consensus on this topic. It appears, at times, that it may be customary to act by force of habit in formal education, as in other areas. Therefore, it is necessary to conduct further research on the subject and to explore whether there is a need for change in the educational world, following the many changes that society has undergone over the years.

After a brief outline of the numerical technique, we to analyze the dynamics of individual particle suspended in demonstrate the accuracy and robustness of our method the fluid. Progress has been made towards this goal by the by comparing the results with (1) the asymptotic solutions recent finite element simulations of two-dimensional partiat small particle Reynolds number, Rep _ 1, for particle cles suspended in fluid by Feng, Hu, and Joseph (1994 a,b); sedimentation and particles suspended in shear flows, (2) Huang, Feng, and Joseph (1994), and Feng and Joseph 2-D Finite Element simulations of single and multi-particle (1995). These results provide considerable information sedimentation at finite Rep, and (3)experimental results, on the particlemotion and interaction at finite particle We present new results from 3-D computational analysis of Reynolds number.

The results indicate that the sediparticle, remeshing, and projection of the solution from mentation dynamics of prolate spheroid objects in a chanthe previous time step onto the remeshed computational nel consists of a series of time-periodic equilibrium states domain at every time step (Hu et.al., 1992). Up to date, with marginal steady states in between, only 2-D solutions have been reported due to the excessive computational time required by this approach.

Quantum liquid of repulsively bound pairs of particles in a lattice

Repulsively interacting particles in a periodic potential can form bound composite objects, whose dissociation is suppressed by a band gap. Nearly pure samples of such repulsively bound pairs of cold atoms---``dimers''---have recently been prepared by Winkler et al. [Nature (London) 441, 853 (2006)]. We here derive an effective Hamiltonian for a lattice loaded with dimers only and discuss its implications for the many-body dynamics of the system. We find that the dimer-dimer interaction includes strong on-site repulsion and nearest-neighbor attraction which always dominates over the dimer kinetic energy at low temperatures. The dimers then form incompressible, minimal-surface ``droplets'' of a quantum lattice liquid. For low lattice filling, the effective Hamiltonian can be mapped onto the spin-$1∕2$ $XXZ$ model with fixed total magnetization which exhibits a first-order phase transition from the droplet to a gas phase. This opens the door to studying first-order phase transitions using highly controllable ultracold atoms.
Defeasible Inference with Circumscriptive OWL Ontologies

The Web Ontology Language (OWL) adheres to the openworld assumption and can thus not be used for forms of nonmonotonic reasoning or defeasible inference, an acknowledged desirable feature in open Semantic Web environments. We investigate the use of the formalism of circumscriptive description logics (DLs) to realise defeasible inference within the OWL framework. By example, we demonstrate how reasoning with (restricted) circumscribed OWL ontologies facilitates various forms of defeasible inference, also in comparison to alternative approaches. Moreover, we sketch an extension to DL tableaux for handling the circumscriptive case and report on a preliminary implementation.
Effect of Peripheral Heart Action on Body Composition and Blood Pressure in Women with High Blood Pressure

Objectives: Exercise is non-medical treatment and low-risk strategy for people with hypertension. Therefore, the aim of this study was to evaluate the effect of peripheral heart action (PHA) on body composition and blood pressure in women with high blood pressure. Methods: Twenty women (age = 38 - 46 years, BMI = 21 - 31 kg/m2) who had high blood pressure (135/88 mm Hg) volunteered to participate. Ten were randomly selected and submitted to 32 PHA exercise sessions. The remaining 10 participants served as a non-exercise control group. Systolic (SBP) and diastolic blood pressure (DBP), skinfold, and 1RM tests of maximum strength were determined before and after 36 exercise sessions. Results: SBP and DBP were decreased significantly (P < 0.05) in the PHA group but not in the non-exercise control group. Furthermore, the training group made significant improvements in test of one-repetition maximum and body composition compared to the control group (P < 0.05). Conclusions: Resistance exercises using the PHA approach can be considered as a low-risk treatment for people with high blood pressure in order to improve blood pressure, increase muscular strength, and enhance overall fitness.
COSTA RICA RIFT ZONE BASALTS : GEOCHEMICAL AND EXPERIMENTAL DATA FROM A POSSIBLE EXAMPLE OF MULTISTAGE MELTING

Chemical compositions and 1-atm. phase relations were determined for basalts drilled from Holes 501, 5O4A, 504B, 505, and 5O5B on Legs 68, 69, and 70 of the Deep Sea Drilling Project. Chemical, experimental, and petrographic data indicate that these basalts are moderately evolved (Mg' values from 0.60 to 0.70), with olivine plus Plagioclase and often clinopyroxene on the liquidus. Chemical stratigraphy was used to infer that sequential influxes of magma into a differentiating magma chamber or separate flows from different magma chambers or both had occurred. Two major types of basalt were found to be inter layered: Group M, a rarely occurring type with major element chemistry and magmaphile element abundances within the range of the majority of ocean-floor basalts (TiO2 = 1.3%, Na2O 2.5%,Zr = 103 ppm, Nb 2.5 ppm, and Y = 31 ppm); and Group D, a highly unusual series of basalt compositions that exhibit much lower magmaphile element abundances (TiO2 = 0.75-1.2%, Na2O = 1.7-2.3%, Zr = 34-60 ppm, Nb = 0.5-1.2 ppm, and Y = 16-27 ppm). The liquidus temperatures of the Group D basalts are high (12301260°C) compared with those of other ocean-floor basalts of similar Mg' values. They have high CaO/Na2O ratios (5-8) and are calculated to be in equilibrium with unusually calcic Plagioclase (An78_g4). The two basalt groups cannot be related by fractionation processes. However, constant Zr/Nb ratios ( 40) for the two groups suggest a single mantle source, with differences in magmaphile element abundances and other element ratios (e.g., Zr/Ti, Zr/Y, Ce/Yb) arising through sequential melting of the same source. Magmas similar to Group D, if mixed with more typical mid-ocean-ridge basalt (MORB) magmas in shallow magma chambers, could provide a source for the highly calcic Plagioclase phenocrysts that appear in more common (i.e., less depleted) phyric ocean-floor basalts.
Correlations between Thermal Environment and Egg Quality of Two Layer Commercial Strains

Heat stress limits the productivity of laying hens, as reflected by egg production and egg quality. The present study aimed at showing the correlations between egg quality parameters and environmental variables recorded on the day eggs were laid and on the previous days. Birds were housed in battery cages in a commercial poultry house. Main component analyses were used to verify associations between environmental and production variables, and Pearson's linear correlation tests were used to further investigate those associations. Analyses were carried out separately for to layer strains, Dekalb ® White and Hy-Line ® w36, and the variables egg weight (g), eggshell weight (g), specific gravity (g/cm³) and eggshell percentage (%) were compared with the environmental variables of the same day of the production, and one, two, three, and four days before egg production. Sound intensity measured inside the houses was positively associated with the quality parameters of eggs produced on the next day. Thermal environmental variables affected the egg quality differently in each strain, particularly air temperature, internal roof tile temperature, relative humidity, and air velocity. Ammonia concentration measured inside the houses was lower than 1ppm, and did not affect production performance.
A Contribution to the Hellenic Open University: Evaluation of the pedagogical practices and the use of ICT on distance education

This study examines a) the methods used to structure the pedagogy necessary to underpin distance education delivery used by the Hellenic Open University (HOU); b) the adoption of pedagogical and epistemological conceptual systems HOU uses for the development of its pedagogical practices; and c) the role of information and communication technology (ICT), and the degree of ICTs incorporation into distance education delivery at HOU. This study shows that: a) in terms of providing rigorous course contents, strong framing exists between HOU’s various learning modules; b) in terms of pedagogical practices, there is a strong hierarchical relationship and framing between HOU’s academic staff and tutors, while conversely, framing is weaker between its tutors and students; c) in terms of ICT usage HOU, in general, uses technology for administration, while conversely, and depending on the program of study, it currently only has limited use for student learning.
Alien fish species in upper Sakarya River and their distribution.

Sakarya River is one of the most important fishing areas in Turkey. The river provides reproduction and survival areas which are suitable for many fish species by means of both the warm water sources and the wide flood plains. However, the fact that the flood plains have been reclaimed, excessive hunting, destruction of the ecologic balance and invasion of the area by the alien fish species threatens the fish stocks in Sakarya River. In this study, we aimed to determine the dispersion area of Carassius gibelio (Bloch, 1782), Oreochromis niloticus (Linnaeus, 1758) and Clarias gariepinus (Burchell, 1822) as the alien fish species. Between years 2005 and 2010, the dispersion areas of these three species in Sakarya River have been determined by means of catching in irregular time periods in the entire Sakarya River. The dispersion details of every of the three species has been yielded with this study for the first time and the natural populations created by O. niloticus in Sakarya River was determined for the first time in this study. Key words: Carassius gibelio, Oreochromis niloticus, Clarias gariepinus, Sakarya River.
