The Annual Migration Cycle of Emperor Geese in Western Alaska

Most emperor geese ( Chen canagica ) nest in a narrow coastal region of the Yukon-Kuskokwim Delta (YKD) in western Alaska, but their winter distribution extends more than 3000 km from Kodiak Island, Alaska, to the Commander Islands, Russia. We marked 53 adult female emperor geese with satellite transmitters on the YKD in 1999, 2002, and 2003 to examine whether chronology of migration or use of seasonal habitats differed among birds that wintered in different regions. Females that migrated relatively short distances (650–1010 km) between the YKD and winter sites on the south side of the Alaska Peninsula bypassed autumn staging areas on the Bering Sea coast of the Alaska Peninsula or used them for shorter periods (mean = 57 days) than birds that made longer migrations (1600–2640 km) to the western Aleutian Islands (mean = 97 days). Alaska Peninsula migrants spent more days at winter sites (mean = 172 days, 95% CI: 129–214 days) than western Aleutian Island migrants (mean = 91 days, 95% CI: 83–99 days). Birds that migrated 930–1610 km to the eastern Aleutian Islands spent intermediate intervals at fall staging (mean = 77 days) and wintering areas (mean = 108 days, 95% CI: 95–119 days). Return dates to the YKD did not differ among birds that wintered in different regions. Coastal staging areas on the Alaska Peninsula may be especially important in autumn to prepare Aleutian migrants physiologically for long-distance migration to winter sites, and in spring to enable emperor geese that migrate different distances to reach comparable levels of condition before nesting.
ISO-SWS calibration and the accurate modelling of cool-star atmospheres ? IV. G9 to M2 stars ??

A detailed spectroscopic study of 11 giants with spectral type from G9 to M2 is presented. The 2.38-4.08 m wavelength-range of band 1 of ISO-SWS (Short-Wavelength Spectrometers on board of the Infrared Space Observatory) in which many dierent molecules - with their own dependence on each of the stellar parameters - are absorbing, enables us to estimate the eective temperature, the gravity, the microturbulence, the metallicity, the CNO-abundances, the 12 C= 13 C-ratio and the angular diameter from the ISO-SWS data. Using the Hipparcos' parallax, the radius, luminosity and gravity-inferred mass are derived. The stellar parameters obtained are in good agreement with other published values, though also some discrepancies with values deduced by other authors are noted. For a few stars ( Dra, Dra, Tuc, H Sco and Cet) some parameters - e.g. the CNO-abundances - are derived for the first time. By examining the correspondence between dierent ISO-SWS observations of the same object and between the ISO-SWS data and the corresponding synthetic spectrum, it is shown that the relative accuracy of ISO-SWS in band 1 (2.38-4.08m) is better than 2% for these high-flux sources. The high level of correspondence between observations and theoretical predictions, together with a confrontation of the estimated Te (ISO) value with Te values derived from colours - which demonstrates the consistency between V K, BCK, Te andd derived from optical or IR data - proves that both the used marcs models to derive the stellar quantities and the flux calibration of the ISO-SWS detectors have reached a high level of reliability.
Physical Activity and Nutrition Status in the University Students: A Mix method Study

Introduction: This study examined the beliefs of a group of university students about physical activities, healthy nutritional patterns in the context of Tehran, Iran. Methods: This study was a mixed method. Participants of the study were 100 university students that selected by convenience sampling method from Tehran-located universities. Interviews and questionnaires were used to collect the data. Results: Only 30% of them had regular physical activity. Body Mass Index (BMI) has mostly been in the normal range and % 17 were overweight. The important barriers were university courses, living in out-of-home settings, and time shortage as the factors barred them from having physical activities and healthy nutrition patterns. Students’ knowledge about the benefits of a healthy lifestyle was desirable. Conclusions: Living in academic settings and preparing for exams which triggers stress, reduce nutrition pattern and physical activities as two factors related to life quality. Therefor, planning and evaluation of environmental health-promoting interventions was proposed.
A Problem-Based Schema Analysis in Algebra

The development of students' algebraic understanding is generally accepted to be one of the major goals of K-12 mathematics teaching. In this paper I attempt to examine this understanding by characterising a group of high school students' algebraic knowledge and patterns of use of that knowledge during the solution of selected problems. Results show that these students tended to show acceptable levels of proficiency with problems that involve substitution of values for variables, and simplification of equations. However, students experienced difficulties with the solution of equations and the interpretation of variables both in symbolic and graphical modes. These results are interpreted as suggesting that the participating students' understanding was--buttressed mainly by schemas that were dominated by procedural knowledge of algebra.
Research on the Application of Hybrid Fiber Reinforced High Performance Concrete in Civil Engineering

This paper presents the hybridization of different types of fibers to overcome their shortcomings, to integrate their advantages, and to subsequently achieve the best performance-to-price ratio. In addition, through hybridization, the mechanical properties of the FRP composites can be tailored for specific applications. The behavior of hybrid FRP tendons was studied experimentally and analytically. Then, the behavior of partially pre-stressed FRP-RC deck slabs with the developed hybrid FRP tendons was experimentally investigated. Finally, numerical study on the pre-stressed FRP-RC bridge deck slab was conducted; the numerical study examines the macro and micro behavior of concrete bridge deck slabs reinforced with partially pre-stressed fiber reinforced polymers (FRP) bars under the effect of a concentrated load. Finally, a comprehensive parametric study was conducted.
An analysis of milk quota abolition impact on Scottish farmers’ behaviour

This paper analyses factors influencing Scottish dairy farmers’ intentions to change size of business in response to milk quota abolition. The analysis uses structural equation modelling and is based on survey data collected in 2009 through telephone interviews with 533 farmers. Results suggest that farmers who (1) intend to leave their farm to children; (2) have not inherited their farm from previous generation; (3) perceive a lower impact of milk quota abolition on business; (4) have less negative attitudes towards policies/regulations; and (5) perceived a lower influence of policies/markets on business during the past decade are most likely to increase farm size.
Surface Preparation of InAs (110) Using Atomic Hydrogen

Atomic hydrogen cleaning has been used to produce structurally and electronically damage-free InAs(110) surfaces. X-ray photoelectron spectroscopy (XPS) was used to obtain chemical composition and chemical state information about the surface, before and after the removal of the atmospheric contamination. Low energy electron diffraction (LEED) and high-resolution electron-energy-loss spectroscopy (HREELS) were also used, respectively, to determine the surface reconstruction and degree of surface ordering, and to probe the adsorbed contaminant vibrational modes and the collective excitations of the clean surface. Clean, ordered and stoichiometric InAs(110)-(1×1) surfaces were obtained by exposure to thermally generated atomic hydrogen at a substrate temperature as low as 400oC. Semi-classical dielectric theory analysis of HREEL spectra of the phonon and plasmon excitations of the clean surface indicate that no electronic damage or dopant passivation were induced by the surface preparation method.
New species of Yochelcionella ( Mollusca ; Helcionelloida ) from the Lower Cambrian ojf North Greenland

Two new species of the helcionelloid mollusc genus Yochelcionella Runnegar & Pojeta, 1974 are described from Lower Cambrian $tTata within the Br0nlund Fjord Group of central North Greenland. Yochelcionella greenlandica n. sp. is also tentatively identified from continental slope deposits of the Browns Pond Formation of New York and the 'Anse Maranda Formation' of Quebec. The internal mould of the almost orthoconic Yochelcionella gracilis n.sp. shows a pegma-like fissure be­tween the apex and the snorkel, a feature ortherwise only reported in Y. fissurata Hinz-Schallreuter, 1997 from the Middle Cambrian of Bornholm.
Elemental Composition of Red Wines in Southeast Turkey

Deg I rmencI Karatas D. , Aydin F. , Aydin I. , Karatas H. (2015): Elemental composition of red wines in Southeast Turkey. Czech J. Food Sci., 33: 228–236. Mineral profiles of wines and soil extracts were analysed in the five most popular international wines (Cabernet Sauvi gnon, Syrah, Merlot, Cot, and Tannat) and national Bogazkere, which is one of the highest-quality grapevine varieties grown in Turkey. We carried out study to establish the mineral and metal concentrations in wines from Southeast Anatolia of Turkey. The ICP-OES method was used for accurate determination of concentrations of 12 elements in cluding Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn. The high levels of iron, potassium, sodium, and calcium were observed in the wine samples analysed. Major elements were also abundantly found in the soil samples. Minor element contents of wine samples were compatible with results other researches. The amount of metal content in wine is an important issue. A remarkable finding of the study was that heavy metals like Pb (found below acceptable limits only in three samples), Co, and Cd were not detected. The results obtained did not exceed the maximum acceptable limits established by the Office International de la Vigne et du Vin. Our results showed that the mineral compositions of wine and soils were interrelated. The analysis of the soil samples taken from the vineyard locations showed similar results for highest composition of major minerals. The characteristics of the wines produced in the Southeast Region of Turkey were analysed for the first time.
Understanding the Results of Multiple Linear Regression

Multiple linear regression (MLR) remains a mainstay analysis in organizational research, yet intercorrelations between predictors (multicollinearity) undermine the interpretation of MLR weights in terms of predictor contributions to the criterion. Alternative indices include validity coefficients, structure coefficients, product measures, relative weights, all-possible-subsets regression, dominance weights, and commonality coefficients. This article reviews these indices, and uniquely, it offers freely available software that (a) computes and compares all of these indices with one another, (b) computes associated bootstrapped confidence intervals, and (c) does so for any number of predictors so long as the correlation matrix is positive definite. Other available software is limited in all of these respects. We invite researchers to use this software to increase their insights when applying MLR to a data set. Avenues for future research and application are discussed.
Managing Digital Learning Environments: Student Teachers' Perception on the Social Networking Services Use in Writing Courses in Teacher Education.

Limited studies have been conducted to examine how effective and what impacts dealing with students' learning experiences as well as the problems faced by the students. This study focused on English student teachers' experiences on the advantages and problems faced in using Social Networking Services (SNS) in English as Foreign Language (EFL) writing courses which is a part of larger research involving the use of SNS in two state universities in Jambi. This research was conducted in ten classes of two Indonesian universities for one year. This qualitative research involved a total of 6 focus group discussions with 60 students. Prior to focus group discussion, demographic questionnaires were distributed to know general information of all participants in relation to the use of SNS. A thematic analysis revealed general background of the participants in relation to the use of SNS, advantages of SNS use in writing courses, problems faced of the SNS use. The findings contribute to current understanding about how English student teachers experience using SNS. Based on the findings, this research offers policy recommendation to expand the use of SNS in EFL courses.
Interactive comment on “Low-cost multi-stage filtration enhanced by coagulation-flocculation in upflow gravel filtration” by L. D. Sánchez et al

Sánchez et al. (2012) have revisited the topic of direct (or contact) gravel filtration and have presented results on its full-scale application. The results clearly demonstrate the higher treatment efficiencies obtained when resorting to the use of coagulants to enhance the performance of the upflow gravel pre-filters. These results are largely in line with other studies on this form of pre-treatment for slow sand filters (e.g. Ahsan, 1995; Ingallinella et al., 1998; Mahvi et al., 2004; Dorea and Clarke, 2006a; Ahn et al. 2007; Khan and Farooqui, 2011). However, one important aspect of this topic escaped their examination.
Design and Implementation of Distributed Cognitive Medium Access Control Protocol for Multi-hop Mobile Ad Hoc Network with Single Transceiver

Recently, cognitive medium access control (MAC) protocol has played a dominant role in mobile ad hoc network (MANET). However, existing algorithms ignore mobility, multihop nature and channel selection fairness.Thus extension of them becomes a critical issue. In this paper, we attempt to address the improvement of these shortages based on power saving mode (PSM) by redesinging channel sensing and data transmission for nodes deployed with a single transceiver. The contribution of this paper is threefold. First, we present the flowchart of proposed model with announcement traffic indication message (ATIM) and DATA window, resulting in separation of control channel and data channel in time field. To realize it, three types of channel information as state, maintenance time and selection priority are raised, based on which channel sensing, information sharing and channel sorting are realized. Second, we realize channel sensing and state sharing through redefinition and cooperation of control packets to record channel state, idle or busy. Third, we propose multi-hop cooperation, channel state updating/changing and reservation mechanisms to exchange packets, guaranteeing that channel would be used fairly and balanced. Simulation results show that, not only throughput and channel utilization are improved as well as acceptable value of channel vacate time (CVT) and channel opening time (COT), but also multi-hop, mobility and fairness nature are taken into account, which meets the need of MANET.
Building capabilities to manage strategic alliances for Competitive Paper The 26th IMP conference, Budapest

In recent years, academics have attributed alliance success to a firm’s ability to successfully manage their alliances, also called their level of alliance capability. We like to contribute to this growing body of literature by (1) verifying the impact of alliance capability on alliance performance and (2) analyzing the drivers of alliance capability. We measure alliance capability through four types of alliance learning processes and study how each of these processes affect alliance outcome. Furthermore, we take into account several possible drivers of alliance capability such as organizational culture, strategic commitment of the top team, experience and alliance management approach. We refine the results by examining how these factors affect each of the four learning processes underpinning alliance capability. Our research model will be tested on a sample of 189 Belgian companies.
Solar Tracking System

Author(s) Title Number of Pages Date Nam Nguyen Solar Tracking System 39 pages + 3 appendices 23 May 2016 Degree Bachelor of Engineering Degree Programme Electronics Instructor Janne Mäntykoski, Senior Lecturer The goal of this thesis was to develop a laboratory prototype of a solar tracking system, which is able to enhance the performance of the photovoltaic modules in a solar energy system. The operating principle of the device is to keep the photovoltaic modules constantly aligned with the sunbeams, which maximises the exposure of solar panel to the Sun’s radiation. As a result, more output power can be produced by the solar panel. The work of the project included hardware design and implementation, together with software programming for the microcontroller unit of the solar tracker. The system utilised an mbed LPC1768 microcontroller to control motion of two stepper motors, which rotate solar panel in two axes. The amount of rotation was determined by the microcontroller, based on inputs retrieved from four photo sensors located next to solar panel. At the end of the project, a functional solar tracking system was designed and implemented. It was able to keep the solar panel aligned with the sun, or any light source repetitively. A quantitative measurement was also performed, which reported how well tracking system improved output power in comparison with fixed mount. Despite being small-scale, the project is a successful attempt in catching up with recent technologies of solar energy. Design of the solar tracker from this project is also a reference and a starting point for the development of more advanced systems in the future.
An Employment Systems Approach to Turnover: HR Practices, Quits, Dismissals, and Performance

This study examines the relationship between alternative approaches to employment systems and quits, dismissals and customer service, based on cross-sectional and longitudinal data from nationally representative surveys of call center establishments. Contrary to prior literature, the antecedents and consequences of quits and dismissals are quite similar. Comparing three dimensions of employment systems, we find that high involvement work organization and long-term investments and inducements are associated with significantly lower quit and dismissal rates, while short term performance-enhancing expectations are related to significantly higher quit and dismissal rates. Establishments with higher quit and dismissal rates have significantly lower customer service, as reported by managers.
( UK ) / Santander ( Spain ) Learning about Power and Citizenship in an Online Virtual World

Comunicar, n. 40, v. XX, 2013, Scientific Journal of Media Education; ISSN: 1134-3478; pages 49-57 www.comunicarjournal. com ABSTRACT This work presents a research study designed to analyse the development of power relations in a virtual world, known as Habbo Hotel, aimed at the child and teenage market. What motivated this work was the desire to under stand how this company wielded its power through the different agents responsible for taking decisions on the behaviour of the users within this virtual world. Simultaneously, this research went deeply into the type of lessons learnt by users as to citizenship springing from the behaviour rules imposed by the company owning this space. In order to understand what young people were learning about the wielding of power, and the prototype model citizen within the virtual world, we analyse the systems of rules that govern what users can or cannot do, and we proceed to analyse the contents of spaces in which users will talk about the reasons why the company had expelled them from Habbo Hotel. The findings of this work reveal that the application of rules on the part of the company results in the experience inside this virtual world not always being fun, democratic, creative, participative or completely satisfying. This thus questions some of the main arguments proposed by different writers on these new forms of communication.
Ehrenfest Paradox, Sagnac Effect, and the Michelson-Morley Experiment

In this article the resolution of the famous Ehrenfest paradox [1] is presented. The paradox relates to a spinning disk and the Special Relativity Theory (SRT) applied to it. The paradox resolution is based on the proposition that the paradox results from an incorrect application of SRT to a system that is not in an inertial motion. The centrifugal and centripetal forces resulting from the rotation are always present and need to be accounted for. Using the author's previously derived metric for the axially symmetric space-time the effect of centrifugal and centripetal forces can be correctly included. When this is done no paradox is obtained and it is shown that the spinning disk appears to have flat space-time geometry. This finding also provides the correct interpretation of the null result of Michelson-Morley experiment, the correct explanation of the Fizeau experiments, and a simple and consistent explanation of the Sagnac effect. The theoretical descriptions of all these experiments should, therefore, always include the effect of the centrifugal force of Earth's rotation. The measured data from other experiments conducted on rotating systems are explained by the inertial mass increase as correctly described by SRT.
