EXAMINING THE LEVELS OF PERCEPTION OF COMMUNICATION SKILLS IN PHYSICAL EDUCATION AND SPORTS COLLEGE (PESC) STUDENTS IN TERMS OF PRE-DETERMINED VARIABLES ABSTRACT

This study was conducted to identify the levels of perception of communication skills in students’ in the Physical Education and Sports Teaching, Sports Management, and Coaching Education programs in a Physical Education and Sports College. It was investigated whether certain features, such as: gender, age, department, class level, regular participation in any sports branch, location, type of high school graduated from, the department graduated from in high school, the education level of the parents’, the parents’ occupations, the number of siblings in each family, and the family’s total monthly income, would cause a significant difference in the levels of perception of communication skills among the students’. Subject group consisted of the 1, 2, 3, and 4 year students from Manisa Celal Bayar University Physical Education and Sports College. A total of 466 students, including 161 female and 305 male, participated in this study. The input data of this study, related to the levels of perception of communication skills, was collected by means of the “Communication Skill Evaluation Scale”, whose validity and reliability were checked on students later, developed by Korkut (1997). Data was also collected by means of the “Personal Information Form”, which was prepared by the investigator in order to identify the demographic features of the students. The given information was evaluated ANOVA and "t" test techniques. The results of this study indicate that the levels of perception of communication skills in the Physical Education Sports College students were quite high. Also, according to the gender of the participants, a significant difference was found in favor of the female students in regards to the levels of * Bu çalışma Yükseklisans tezinden hazırlanmış 6.

Responses to conspecific density in an arborescent bryozoan

Sessile colonial invertebrates that must tolerate environmental variation without the luxury of mobility may be expected to cope with such variation through phenotypic plasticity. While plastic responses to a range of biotic factors (e.g. predation) are increasingly documented, the details of responses to competition (mediated by the densities of conspecifics or heterospecifics vying for the same resources) remain unclear, despite a rich literature for terrestrial plants on which to draw. We examined phenotypic responses to conspecific density in a colonial invertebrate (the arborescent bryozoan, Bugula neritina) under field conditions. We found that colonies at higher densities were generally less fecund, lower in biomass and more elongate than those growing virtually alone. We also found such responses to vary only subtly with the life history stage of neighbours, with colonies exposed to higher densities of contemporary recruits achieving elongation via increased budding between bifurcation points and the elongation of individual zooids, while colonies exposed to established adults achieved elongation via increased budding only. These responses are broadly consistent with those of terrestrial plants competing for light and are probably due to the combined effects of resource limitation and altered flow in high density stands. Future studies are needed to disentangle these effects and the extent to which such responses to density in branching colonial invertebrates are a passive result of food limitation, or reflect active (and potentially adaptive) plasticity to other aspects of the local density environment.
Assessment of Heavy Metals in Water, Sediment, and Fishes of a Large Tropical Hydroelectric Dam in Sarawak, Malaysia

Bakun Hydroelectric Dam in Sarawak is one of the world highest concrete rock filled dams. This paper reports the heavy metals concentrations in water, sediment, and fishes of Bakun Dam. Water and sediment samples were collected from 11 stations and 6 fish species were caught. The samples were digested with open acid digestion and the metals contents were analysed using an atomic absorption spectrophotometer and mercury analyser. The method was validated based on certified reference materials. A higher concentration of Fe and Mn was detected in downstream water with significant longitudinal variation. Cu, Zn, and Hg were present in trace amount. All elements analysed were consistently found in sediment with no risk of contamination. For fish, Hemibagrus planiceps was characterised by higher affinity for Hg accumulation. The concentrations detected in all fish species were within the permissible guideline of 0.5 mg/kg. The health risk assessment suggested that Barbonymus schwanenfeldii, Puntioplites waandersii, Cyclocheilichthys apogon, and Hemibagrus planiceps were characterised by hazard index > 1 implying possible adverse effects. The amount of fish recommended for adults and children was in the range of 500–775 g/week and 33–135 g/week, respectively.
EMISSIONS DURING THE 2002-2007 ERUPTIVE SCENARIOS AT STROMBOLI

We report additional radon data collected at Stromboli during 2002-2007. The whole data set of periodic measurements has been systematically analyzed to retrieve the values of background, threshold and anomaly for all the stations of the network. Maps of radon concentrations in space and time correlate with changes in volcanic activity. Higher radon emissions are essentially concentrated at summit stations and may also affect some stations located onto the summit-eastern sector of the cone (along the N60°E fracture zone), as well as two stations placed at the NE edge of Sciara del Fuoco. Most of these stations are well above their threshold values during effusive eruptions (namely 2002-2003 and 2007) due to the progressive structural adjustment of the volcano edifice coupled with the opening and resetting of the fracture network. A two-year-long timeseries of automatic Rn measurements (2005-2007) was analyzed together with local environmental parameters and selected geophysical data (on seismic tremor and infrasonic puffing). The data show good correlation between radon and the latter parameters
High-Density, Compact H II Regions in the Starburst Galaxies NGC 3628 and IC 694: High-Resolution VLA Observations of the H92α Radio Recombination Line

Using the Very Large Array (VLA), we have observed the H92α line in the nuclear regions of NGC 3628 and Arp 299 (IC 694 + NGC 3690) with an angular resolution of 1''. The radio recombination lines could provide quite important constraints to the physical conditions for the ionized gas in the nuclear regions. For the central nuclear components in NGC 3628, IC 694, and NGC 3690, we find that the electron density of the ionized gas is in the range 5 × 102 to 5 × 104 cm-3, with corresponding geometrical sizes ranging from 25 to 0.01 pc. For the regions with a large line-to-continuum ratio, such as the anomalous kinematic components in IC 694 and NGC 3628, the electron density of the H II regions is well constrained. The derived parameters suggest the existence of ~100 high-density, compact H II regions (ne ~ 104 cm-3 and l ~ 1-2 pc) in these two components. The large number of high-density, compact H II regions deduced for these components can be regarded as evidence for enhanced massive star formation in anomalous kinematic structures that are often produced in interacting systems. Our new H92α line observations reveal the presence of rotating circumnuclear ionized gas disks in both NGC 3628 and IC 694. From the analysis of the nuclear kinematics, we find that a total dynamical mass of 3 × 108 M☉ exists within a radius R = 120 pc in NGC 3628 and 7 × 108 M☉ within R = 200 pc in IC 694. The kinematics of the ionized gas and the models with a collection of H II regions infer that the ratio of H II to dynamical mass in the starburst nuclei varies from 1 × 10-4 (for the high-density, compact H II region model) to 1 × 10-2 (for the low-density, large H II region model).
The Impact of Earnings Quality on the Cost of Equity: Evidence from Privatized Firms

In this paper, we examine whether earnings quality affects cost of equity in privatized firms. Using a multinational sample of firms privatized in developing and industrialized countries, we find strong, robust evidence that the cost of equity is positively related to the absolute value of abnormal accruals. This finding suggests that firms with lower earnings quality are penalized with a higher cost of equity.
Friendship Pattern as a Correlate of Age and Gender Differences among Urban Adolescents

Abstract This study was conducted to assess the gender differences in the pattern of friendships among urban adolescents (14-17 years). The study was based upon a sample of 200 adolescents (100 boys and 100 girls) drawn equally from four randomly selected schools of Ludhiana city. A list of all students aged between 14-17 years in selected schools was prepared by ascertaining their date of birth from school records. 50 boys and 50 girls from two age groups, that is, 14-15.5 and 15.5-17 years were taken to make a total of 100 boys and 100 girls. The results revealed that females exhibited significantly more intense friendship as compared to their male counterparts, yet the differences were greater in the older adolescents as compared to the younger ones. Friendship patterns in males were better in younger years whereas, females exhibited almost similar patterns of friendship in both the age-groups
The radiative consistency of Atmospheric Infrared Sounder and Moderate Resolution Imaging Spectroradiometer cloud retrievals

[1] The consistency of cloud top temperature (TC) and effective cloud fraction (f) retrieved by the Atmospheric Infrared Sounder (AIRS)/Advanced Microwave Sounding Unit (AMSU) observation suite and the Moderate Resolution Imaging Spectroradiometer (MODIS) on the EOS-Aqua platform are investigated. Collocated AIRS and MODIS TC and f are compared via an “effective scene brightness temperature” (Tb,e). Tb,e is calculated with partial field of view (FOV) contributions from TC and surface temperature (TS), weighted by f and 1−f, respectively. AIRS reports up to two cloud layers while MODIS reports up to one. However, MODIS reports TC, TS, and f at a higher spatial resolution than AIRS. As a result, pixel-scale comparisons of TC and f are difficult to interpret, demonstrating the need for alternatives such as Tb,e. AIRS-MODIS Tb,e differences (ΔTb,e) for identical observing scenes are useful as a diagnostic for cloud quantity comparisons. The smallest values of ΔTb,e are for high and opaque clouds, with increasing scatter in ΔTb,e for clouds of smaller opacity and lower altitude. A persistent positive bias in ΔTb,e is observed in warmer and low-latitude scenes, characterized by a mixture of MODIS CO2 slicing and 11-μm window retrievals. These scenes contain heterogeneous cloud cover, including mixtures of multilayered cloudiness and misplaced MODIS cloud top pressure. The spatial patterns of ΔTb,e are systematic and do not correlate well with collocated AIRS-MODIS radiance differences, which are more random in nature and smaller in magnitude than ΔTb,e. This suggests that the observed inconsistencies in AIRS and MODIS cloud fields are dominated by retrieval algorithm differences, instead of differences in the observed radiances. The results presented here have implications for the validation of cloudy satellite retrieval algorithms, and use of cloud products in quantitative analyses.
Agronomic performance of ' Cabernet Sauvignon ' with leaf removal management in a high-altitude region of Southern Brazil

The objective of this work was to compare the effect of different times of leaf removal on the vegetative-productive efficiency and on the chemical and physical characteristics of 'Cabernet Sauvignon' clusters in a high-altitude region of the state of Santa Catarina, Brazil. The experiment was conducted in the 2015 and 2016 vintages, in a commercial vineyard, located in the municipality of São Joaquim, in the state of Santa Catarina, at 1,230-m altitude. The treatments consisted of different times leaf removal in the cluster zone, in the following phenological stages: full bloom, buckshot berries, pea-sized berries, veraison, and 15 days after veraison, besides a control without leaf removal. The evaluated variables were subjected to the analysis of variance and compared with the Scott-Knott test, at 5% probability. In a high-altitude region, leaf removal provides more adequate indices for plant vegetative:yield balance. It also increases yield when performed during the pea-sized berry and veraison stages, increases the fertility index when performed during the pea-sized berry stage, and improves the chemical composition of 'Cabernet Sauvignon' grape when performed up to the pea-sized berry stage. The obtained results show the importance of early leaf removal to obtain must with potential for the production of quality wines.
Toxicity of Diuron, Diquat and Terbutryn to Cyanobacterial Mats

This study investigated acute toxicity of Diuron, Diquat and Terbutryn to cyanobacterial mats collected from Wadi Gaza, Palestine. Toxicity was measured by the reduction of population growth of cyanobacterial mats exposed to various herbicide concentrations in the range of 0-15.44 μmole L-1. Optical density of cyanobacterial suspension was recorded using a spectrophotometer at 680 nm from time zero up to 8 days and taken as an indicator of growth. EC50 and ET50 values were estimated using linear regression equations. Results showed that cyanobacterial mats adapted and grew fast under laboratory conditions. The toxicity of Diuron, Terbutryn and Diquat reached 89.35, 76.02 and 71.24%, respectively. Toxicity of binary mixtures (Diuron and Diquat) decreased from 77.35% to 65.33% due to the reduction of Diuron concentration in the mixture. EC50 values for Diuron, Terbutryn and Diquat were 0.009, 0.031and 0.381 μmole L-1 whereas ET50 values were 32.32, 35.89 and 23.45 h, respectively. EC50 values of binary mixtures (B1-B3) were 0.004, 0.01 and 0.012 toxicity units. Tertiary mixtures (T1-T7) had a wide range of EC50 (0.043-2.9E-07) TUs. The mixture toxicity index (MTI) had positive and negative value in mixtures, indicating synergetic and antagonistic effects. Application of the above-mentioned herbicides may severely damage the ecosystem. Our results are the first of its kind in the region and may be considered as a guideline for future studies.
Port-Hamiltonian descriptor systems

The modeling framework of port-Hamiltonian systems is systematically extended to constrained dynamical systems (descriptor systems, differential-algebraic equations). A new algebraically and geometrically defined system structure is derived. It is shown that this structure is invariant under equivalence transformations, and that it is adequate also for the modeling of high-index descriptor systems. The regularization procedure for descriptor systems to make them suitable for simulation and control is modified to deal with the port-Hamiltonian structure. The relevance of the new structure is demonstrated with several examples.
Skype™ Conference Calls: A Way to Promote Speaking Skills in the Teaching and Learning of English

This article presents the results of a research project on the teaching and learning of English through the use of Skype™ conference calls. The research was carried out with a group of 12 English as a foreign language adult learners in the language institute of Universidad Distrital Francisco Jose de Caldas, Bogota, Colombia. The findings of this study suggest that Skype™ conference calls might be considered as an influential computer-mediated communication tool in order to promote English as a foreign language adult A1 learners’ speaking skill, especially for social interaction purposes and oral reinforcement of both language fluency and course contents outside of classroom settings.
Information Privacy Concerns, Procedural Fairness, and Impersonal Trust: An Empirical Investigation

This research addresses the tensions that arise between the collection and use of personal information that people provide in the course of most consumer transactions, and privacy. In today's electronic world, the competitive strategies of successful firms increasingly depend on vast amounts of customer data. Ironically, the same information practices that provide value to organizations also raise privacy concerns for individuals. This study hypothesized that organizations can address these privacy concerns and gain business advantage through customer retention by observing procedural fairness: customers will be willing to disclose personal information and have that information subsequently used to create consumer profiles for business use when there are fair procedures in place to protect individual privacy. Because customer relationships are characterized by social distance, customers must depend on strangers to act on their behalf. Procedural fairness serves as an intermediary to build trust when interchang eable organizational agents exercise considerable delegated power on behalf of customers who cannot specify or constrain their behavior. Our hypothesis was supported as we found that when customers are explicitly told that fair information practices are employed, privacy concerns do not distinguish consumers who are willing to be profiled from those who are unwilling to have their personal information used in this way.
Evaluation of Long-Distance Orientation in Birds on the Basis of Migration Routes Recorded by Radar and Satellite Tracking

Predicted flight trajectories differ depending on which orientation cues are used by migrating birds. Results from radar and satellite tracking of migrating birds can be used to test which of the predicted trajectories shows the best fit with observed flight routes, supporting the use of the associated orientation mechanism. Radar studies of bird migration at the Northeast Passage and the Northwest Passage support the occurrence of migration along sun compass routes in these polar regions. In contrast, satellite tracking of Brent geese (Branta bernicla) migrating from Iceland across Greenland and from Northwest Europe to Siberia show routes that conform most closely with geographic loxodromes, but which are also profoundly influenced by large-scale topography. These evaluations are discussed in relation to the adaptive values of different routes in different parts of the world. Sun compass routes are favourable mainly for east-west migration at high latitudes. For east-west migration at mid and high latitudes magnetic loxodromes are more favourable than geographic loxodromes in certain regions while the reverse holds in other regions. The geometry of migration routes, as recorded by radar and satellite tracking, may be important for understanding the evolution of the complexity of birds' orientation systems, and for providing clues about the orientation mechanisms guiding the birds on their global journeys.
Runup kinematics on a natural beach

Runup kinematics on a gently sloping natural beach are examined with detailed measurements from video images, resistance wires deployed at five elevations (between 5 and 25 cm) above and parallel to the beach face, and pressure sensors located in the inner surf zone. As suggested in a previous study comparing a single-level resistance wire and manually digitized films, runup measurements are sensitive to the sensor elevation above the bed, owing to the elongated shape of the runup tongue. The measured mean runup elevation (setup) and vertical excursion increase as the sensor elevation decreases, with the video-based runup estimates having the maximum means and variances. For the six data runs the average ratios of the videobased setup and significant runup excursion to estimates based on wires elevated 15 cm above the bed are 2.7 and 1.5, respectively. These trends, combined with the high coherence and small phase difference between the video and the lowest wire, demonstrate that the video-based estimates correspond to a very near-bed (less than a few centimeters elevation) wire measurement. The measured increase in runup excursion with decreasing sensor elevation and the cross-shore variation in the amplitudes of pressure fluctuations at infragravity frequencies, are consistent with the theory for linear, in viscid, normally incident standing waves. For example, valleys in the pressure spectra occur at approximately the predicted standing wave nodal frequencies. Also in accord with small-amplitude wave theory, observed swash excursions are nearly identical to pressure fluctuations at the location of the measured runup mean (for pressure sensors located seaward of the most offshore bed-level rundown). However, at very low frequencies, where reflection is typically assumed complete and dissipation negligible, the observed, near-bed swash magnitudes are overamplified relative to a best fit of the linear standing wave model based on the amplitude and phase of the seaward observations.
Effect of Doxorubicin on Histomorphology of Liver of Wistar Albino Rats

Doxorubicin is associated with adverse effects on organs like liver. This study was done to find the effects of doxorubicin on liver of wistar albino rats. Sixty healthy wistar albino rats were taken for the study. The rats were randomly divided in to 4 groups (2 experimental groups; group A1 and A2, and 2 control groups;group B1and B2 each containing 16 rats). The experimental groups were given a single dose of doxorubicin i.e. 10 mg/kg body weight intraperitoneally and sacrificed after 7 days and 14 days for each group. Rats under control groups were given a single intraperitoneal dose of 2.5 ml/kg body weight normal saline and sacrificed with their respective experimental groups. A significant difference (p < 0.001) and (p = 0.005) in final body weight was observed among group A1 experimental and B1 control rats, and among group A2 experimental and B2 control rats. As compared to group B2 control, group A2 experimental rats had significantly (p = 0.043) lower liver weight. Diameter of hepatocyte (p < 0.001 for both groups) and nucleus (p=0.004 for group A1 and control B1, and p < 0.001 for group A2 and control B2) was significantly higher in experimental rats as compared to their respective controls. Cross-sections of the liver of both control groups had normal architecture. However, there was progressive destruction of liver architecture across the experimental groups. Doxorubicin causes the disruption of normal architecture of liver in rats. Thus care needs to be taken during doxorubicin chemotherapy to minimize effects on liver.
