Sample Representation and Substantive Outcomes Using Web With and Without Incentives Compared to Telephone in an Election Survey
Authors: Lipps Oliver , Pekari Nicolas 
Published: March 2016

Abstract
The objective of this article is to understand how the change of mode from telephone to web affects data quality in terms of sample representation and substantive variable bias. To this end, an experiment, consisting of a web survey with and without a prepaid incentive, was conducted alongside the telephone Swiss election survey. All three designs used identical questionnaires and probability samples drawn from a national register of individuals.
First, our findings show that differences in completion rates mostly reflect different levels of coverage in the two modes. Second, incentives in the web survey strongly increase completion rates of all person groups, with the exception of people without Internet access or limited computer literacy. Third, we find voting behavior to be much closer to official figures in the web with the incentive version compared to the two other designs. However, this is partly due to the different sociodemographic compositions of the samples. Other substantive results suggest that the incentive version includes harder-to-reach respondents. Unit costs are much lower in the two web designs compared to the telephone, including when a relatively high incentive is used. We conclude that in countries with high Internet penetration rates such as Switzerland, web surveys are already likely to be highly competitive.

<p>The study of morphological variability <em>Harpalus rufipes</em> (De Geer) hemocytes was carried out. <em>Harpalus</em> <em>rufipes</em> (De Geer) is a field polyzonal species found almost throughout the temperate zone of Eurasia and North America. Structure of the population of hemocytes was studied. We identified seven types of cells: adipohemocytes, granulocytes, plasmatocytes, prohaemocytes, shperulocytes, cystocytes, and oenocytes. The effect of different plant and animal diets on linear dimensions of hemocytes and their nuclei was studied. In all samples the shperulocytes and oenocytes had the largest size; theirs large and small diameter were 18.14 ± 6.51 and 15.85 ± 5.03 µm, 17.08 ± 2.93 and 14.43 ± 2.16 µm respectively. Prohaemocytes were the smallest: 10.95 ± 2.11 and 9.59 ± 1.85 µm. Linear dimensions N<sub>1</sub> and N<sub>2</sub> of oenocytes, cystocytes and shperulocytes were 8.83 ± 3.13 and 6.81 ± 1.64, 8.70 ± 2.42 and 6.34 ± 1.99, 8.41 ± 3.15 and 6.71 ± 2.25 µm respectively. Among four sunflower feeding the largest size were registered for adipohemocytes, prohaemocytes, shperulocytes and oenocytes. Maximum sizes of granulocytes, plasmatocytes and cystocytes were fixed during millet and wheat feeding. The chemical composition of food intake had different effects on certain types of hemocytes, leading to increase or decrease in their size. Among six animal feeding we registered the largest size for adipohemocytes, plasmatocytes, cystocytes, and oenocytes towards Sarcophagidae sp. larvae. In all samples the largest size had shperulocytes and oenocytes. The hemocytes of imago changed their sizes insignificantly regards plant or animal food, which testifies a physiological adaptation of beetle feeding towards food items.</p> <p><em>Key words: morphological variability, hemocytes, Harplus rufipes, feeding.</em></p><p> </p><p><a href="http://dx.doi.org/10.7905/bbmspu.v5i1.969"><strong>http</strong><strong>://</strong><strong>dx</strong><strong>.</strong><strong>doi</strong><strong>.</strong><strong>org</strong><strong>/10.7905/</strong><strong>bbmspu</strong><strong>.</strong><strong>v</strong><strong>5</strong><strong>i</strong><strong>1.969</strong></a><strong> </strong></p><p><em><br /></em></p>

Published: March 2016

ZusammenfassungGegenstand: Komplexe Auswertung 5-jähriger Stoffwechselanalysen in Kleinbetrieben hinsichtlich Indikationen, Durchführung und Ergebnissen.Material und Methoden: Insgesamt 793 Blutserumproben von Kühen in unterschiedlichen Laktationsstadien sowie von Färsen (122 Einsendungen aus 53 Betrieben) wurden auf die Parameter freie Fettsäuren (FFS), β-Hydroxybutyrat (BHB), Cholesterol, Harnstoff, Kreatinin, Glukose, Gesamteiweiß, Albumin, Bilirubin, Leberenzyme, Kreatinkinase (CK), β-Carotin, Elektrolyte und Spurenelemente untersucht. Ergebnisse: Etwa ein Fünftel der Untersuchungen erfolgten allein zur Kontrolle des Stoffwechselstatus. Die weiteren Einsendungsgründe entsprachen den Merzungsursachen. Die FFS zeigten im Laktationsverlauf ante partum mit 56,7% die häufigsten Referenzwertabweichungen. Bis 8 Wochen post partum (p. p.) verringerte sich dieser Anteil auf 36–38% und später auf < 11%. Die BHB-Referenzwertabweichungen überschritten in der gesamten Laktation 68%. Die Harnstoffkonzentration lag in der Mittel- und Spätlaktation zu 40–50% über dem Referenzbereich. Eine Hypokalzämie trat in der 1. Woche p. p. zu 13,2% auf, eine Hypophosphatämie zu 6,6%. Für die CK wurden Referenzwertabweichungen mit einem Anteil von 60,4–90,9% ermittelt. Ein Selen- und Kupfermangel bestand zu ca. 15%. Färsen wiesen mit 21,3% häufiger als die Kühe eine Kupferunterversorgung auf. Ein β-Carotin-Mangel ergab sich ante partum zu 50% und post partum zu 47,1–77,8%. Nachteilige Referenzwertabweichungen nahmen von 2006 bis 2011 bei FFS, Harnstoff, β-Carotin und Selen zu, korrelierend mit den Milchpreissenkungen 2009 und 2010. Referenzwertabweichungen von BHB, CK, Cholesterol, Kalzium und anorganischem Phosphat blieben auf einem Niveau. In 80% der Betriebe verbesserte sich der Stoffwechselstatus im Kontrollzeitraum. Schlussfolgerung: Auch in kleineren Betrieben decken Stoffwechselscreenings peripartal frühzeitig Ursachen für die häufigsten Merzungsgründe auf und bieten Optionen für korrigierende Maßnahmen.

Published: March 2016

The purpose of the present study was to examine the relationship between critical thinking and translation ability of Iranian English translation students. Moreover, the difference between critical thinking skills of males and females was explored. The participants of this study were 86 Iranian senior English translation students of Islamic Azad University, Islamshahr branch. For gathering data two kinds of instruments were used: a critical thinking questionnaire (The Persian version of CCTST- form B) and English to Persian translation test. The findings revealed no significant difference between critical thinking abilities of females and males. Thus it can be concluded that gender has no role in critical thinking abilities of the Iranian EFL learners. Furthermore, the results of this study indicated that learners with more critical abilities were more successful in translation performance. These findings highlight the importance of teaching thinking skills to our learners and Integrating problem solving activities that need critical thinking in our teaching and learning process.
Students Perception Of Homework Assignments And What Influences Their Ideas
Authors: Letterman Denise 
Published: March 2016

Authors have researched the effects of homework, but few studies have delved into the idea of students attitude towards homework. Consequently, students perception of homework, the principal participants, remains largely unknown. Students experience in homework that started as early as elementary school has influenced their ideas of homework. Trying to get students to complete their homework is one of the most frequent and frustrating behavior problems for educators. The purpose of this study is to understand students perception of homework assignments and identify factors that influenced their ideas. The participants for this research project were 180 undergraduate students enrolled in select Principles of Finance and Corporate Finance classes (encompassing three semesters and nine classes) at Robert Morris University, Pittsburgh, Pennsylvania. Results of the study summarize students opinions of homework assignments while in high school, college, and for the specific course in which the questionnaire was administered. Tests of significance revealed seven (of the nine classes) significant differences between the actual number of times homework was handed in and the pre-conceived number of times students estimated homework assignments would be completed on time.
The Natural Way To Learn: Learn Without Learning

Natural learning ways currently used to accelerate the velocity of learning are reviewed, including Selman’s MEDICASA model with his platoon system of participatory responses---all demonstrating innovative multi-sensory, multi-learning skills. To augment persuasion and articulation ability of business school students, stand-up comedy is used (University of Chicago). Song writing, storytelling and improvisation (Vanderbilt University-Owens Management), and for Shakespearean motivation for other management skills at the corporate executive level (Northrup Grumman). Food “chow-down”, before and during classes, including pizzas, soyburgers and chocolate candy, for relaxation and memory stimulation and retention. The aromatherapy path to soft learning, the path of music and subliminal sound--Mozart effect and silent sound--and other multi-sensory aids and teaching techniques to activate all the senses for learning---Key for three senses, but strive for five! Other learning techniques include Selman’s Universal Method (SUM) of breaking large problems into manageable parts or patches. His MEDICASA Model for developing models for multi-learning in various venues will be demonstrated. Another approach is to have abstract ideas in the sciences translated into physical learning aids, or robotic device, or toys--- where the kernel of the analogies can be retained for comprehending differing situations in the present, and for future metaphors. Learning aids, toys, robotic devices and simulation techniques will be explored for state-of-the-art reinforcement of ideas and innovative concepts at this point in time. When Al Gross (a.k.a. Phineas Thaddeus Veeblefetzer) passed away at the end of the last millennium, the gizmos he designed and had patented---just for the fun of it!-- like Dick Tracy’s two-way wrist radio, the walkie-talkie, and other wireless wonders still have a revered resting place in the heart of our fun memories. Learning can be reinforced in many ways. But learning without play is difficult, grim and boring presentations. It may be the major failing of our educational system!

The Implementation Of Knowledge Management System In Taiwans Higher Education
Authors: Yeh Yaying Mary Chou 
Published: March 2016

Success in an increasingly competitive marketplace depends on the quality of knowledge that organizations apply to their key business processes. The concept of knowledge management (KM) is widely discussed in commercial applications. There are limited discussions as to how it applies to not-for-profit organizations and its relevant measurement issues. This paper examines the application of knowledge management systems (KMS) in a private college in Taiwan, who is facing administrative challenges and cutting-edge competition. The multi-perspective modeling approach is adopted. The college first defines vision in a SWOT analysis through faculty brainstorming sessions. Leadership is formed to ensure a culture of sharing. A knowledge road map then documents inventories of IC and core competence. After defining knowledge management strategies in academic and organizational perspective, the KM model describes steps and procedures for implementation. Finally, implications for other universities and colleges are discussed.
Addressing A Missing Link In Higher Education On-line Content Development: Toward A Tripartite Collaborative Model
Authors: Assogbavi Tov , Grzeda Maurice 
Published: March 2016

Although more than a dozen methods for developing and offering courses through distance education have been utilized over the years, the offering of on-line courses through the “World Wide Web” is still in its infancy. The number of failures in managing such on-line offerings calls for substantial research to explore why some programs are successful while others fail. A few years ago, dozens of business schools in the US were trying to position themselves in what was promised to be a lucrative market for on-line education and training. While some institutions have successfully established internet-based programs, many others have scrapped their on-line projects. Many reasons account for these failures. Among these are misinterpretations of the market, problems faced by traditional schools, start-up costs, choice of development/delivery model and faculty skepticism. While all these reasons have a great impact on the results of the first decade of on-line education experience, this paper focuses on what seems to be the major factor: finding the right on-line model. The paper suggests that an on-line higher education model based on a partnership between the institution, the content experts and the e-learning technology providers is the most functional. This model helps each partner clearly determine an appropriate role, increasing the likelihood of a successful outcome.
Improved Oil Recovery Through Unsteady Waterflooding Conditions- Cyclic Waterflooding Application in Tiguino Field, Ecuador
Authors: Munoz M. A. , Rivadeneira M. V. 
Published: March 2016

Abstract
This paper describes the analysis and positive results of injecting water, from constant to discontinuous rates in a reservoir under a high water cut stage. By following and improving waterflooding surveillance applications it was possible not only to describe the kind of reservoir, but also to keep the water cut up for a longer time. The goal of this study is to demonstrate the powerful benefits of applying and improving the surveillance plots that are available in the existing literature. The pore volumes injected plot, which was enhanced in this study by adding the injection rates per well in a secondary Y axis, was a powerful tool to identify the water cut behavior.
One of the two injector wells of the field was shut in for about 5 months and returned to its water injection conditions for 7 months. These events are presented in three phases. The first is related to the reservoir characterization achieved before the injector shut in. The second includes the well responses observed and monitored during the injector shut in. And, the third illustrates the promising reservoir results after the injector shut in. As well, an economic model is also developed.
As a result of the field events, analysis, and results described in this paper, the reservoir water cut was stable for a longer time in comparison with the whole life of the IOR project. In addition the increase Estimate Ultimate Recovery was 304,968 bbl for 8 years, the net present value of the field increased to 24%, and the average operating cost was reduced to 2.49 USD/bbl from 2015 to 2022.
The cyclic waterflooding existing literature supports reservoir characterization, analysis and results achieved in Tiguino Field. The initial application monitored in Ecuador will be helpful to be considered as a first approach for starting an IOR optimization in similar stratified reservoirs. The results obtained in Tiguino field are helpful not only as a real example but also as a statistical support for cyclic waterflooding. The Tiguino case experience would be extrapolated to other fields worldwide.
Simulation and Optimization of CO2 Huff-and-Puff Processes in Tight Oil Reservoirs
Authors: Kong Bing , Wang Shuhua , Chen Shengnan 
Published: March 2016

Abstract
As one of the unconventional resources, tight oil has become one of the most important contributor of oil reserves and production growth. The successful commercial production of tight oil is mainly reliant on the advancement in horizontal drilling and multistage hydraulic fracturing technique. Development of tight oil reservoirs remains in an early stage. Primary oil recovery factor in these reservoirs is very low, leaving substantial volume of oil trapped underground due to the low porosity, low permeability characteristic of tight oil reservoirs. Thus, investigation of enhanced oil recovery methods is more than imperative in tight oil reservoirs. CO2 Huff-and-Puff technology has been effectively applied in conventional reservoirs and can be tailored to adapt for the characteristics of tight oil reservoirs.
In this study, the performance of water flooding in tight oil reservoir is studied and compared with that of the CO2 Huff-and-Puff process. Sensitivity analysis demonstrates that the performance of CO2 Huff-and-Puff is more sensitive to the length of gas injection and production step in each cycle, compared to the soaking time. The CO2 Huff-and-Puff process is optimized and an adaptive CO2 Huff-and-Puff process is conducted for tight oil reservoirs after primary production. Simulation results show that the adaptive cycle length CO2 Huff-and-Puff process can improve the incremental oil recovery by 11.1% over a fixed cycle length process. Finally, the inter-well interference during CO2 Huff-and-Puff is studied, and it is found that a multi-well asynchronous CO2 Huff-and-Puff pattern can improve the incremental oil recovery by 31.6% over that of a synchronous pattern.

Published: March 2016

Abstract
Recent studies on the use of ammonia as an alkali for performing alkali-surfactant-polymer (ASP) floods have shed light on its advantages over conventional alkalis such as lower alkali requirements, ease of transportation and storage. This study is aimed towards understanding surfactant adsorption in sandstone and carbonate rocks in the presence of ammonia. Zeta potential measurements were performed to characterize Bandera brown sandstone and Silurian dolomite surfaces in the presence of ammonia and sodium carbonate. A series of experiments were performed with and without ammonia such as static surfactant adsorption experiments on crushed Bandera brown sandstone and Silurian dolomite rocks, single phase surfactant transport experiments in sandstone and carbonate cores, surfactant phase behavior to identify an ultra-low interfacial tension (IFT) surfactant formulation, and oil recovery coreflood experiments using these surfactant formulations. Zeta potential measurements showed a reduction in zeta potential of Bandera brown and Silurian dolomite by adding ammonia to increase the pH. Surfactant adsorption experiments showed that ammonia was able to reduce the adsorption on sandstones, but not much difference was observed for carbonates. The ultra-low IFT surfactant formulations developed with and without ammonia showed very similar phase behavior. High oil recoveries and very low surfactant retentions were observed in the oil recovery experiments performed in sandstones.

Published: March 2016

Abstract
Objective/Scope: Associated gas occurring in the offshore production facilities has traditionally been handled by flaring (primarily), gas export, and gas re-injection. Operators and owners have preferred to flare in many cases because gas export and re-injection are either very expensive or infeasible. Global interest in eco-friendly solutions has recently increased in the area of offshore oil & gas fields.
To achieve zero-flaring for oil & gas production site, "Modular Gas-to-Liquids (GTL)" and "GTL Floating Production Storage and Offloading (FPSO)" has been researched as candidate zero-flare methods. Our goal is to develop a portfolio of zero-flare solutions to support business development by making technical & economic comparisons of gas export, gas re-injection and offshore GTL.
Methods, Procedures, Process: In the view of EPC contractor, the technical & economic feasibility study for Offshore GTL application was studied and analyzed. Several gas handling methods (e.g. gas export, gas re-injection, and Offshore GTL) were compared and analyzed to figure out which technology is the best option for associated gas handling for offshore oil & gas fields. We also studied which method would be more competitive depending on gas production capacity, distance from onshore to offshore, crude oil price, and natural gas price in offshore oil & gas fields. Moreover, economic analysis was performed to identify the major cost factors & ranges and to understand their impact on the project.
Results, Observations, Conclusions: The feasibility study of GTL module on FPSO has been lately completed to acquire the preliminary technical & economic comparison of gas export, gas re-injection and Offshore GTL for developing oil & gas fields in offshore. The results of this study suggest that concepts of GTL application can be technically and economically more competitive than gas export and gas re-injection in some offshore oil & gas fields. The GTL products are more profitable than export & re-injection gas in the energy markets within the range of the current project cost factors.
Novel/Additive Information: It must be a great opportunity to set up a cooperation network for the next stage of developing Offshore GTL. The cooperation network will research and develop Pre-FEED for Offshore GTL and the result will bring commercial realization of this innovative approach of oil & gas fields in offshore.
