Materialistic girls watching a materialistic world: fashion TV series and women’s copy-cat intentions
Authors: Voorveld Hilde A. M. , Fakkert Marie-Selien , van Reijmersdal Eva A. 
Published: April 2017

AbstractInspired by the popularity of TV series such as Gossip Girl, The City and The Hills which revolve around the world of fashion, this article examines whether and how these series are related to young women’s willingness to purchase products that allow them to replicate the appearances of the main characters. The results demonstrated that in particular women with materialistic orientations would like to emulate the main characters. The mechanisms underlying this relation are that materialistic women watch fashion TV series to gain fashion inspiration; subsequently they watch these series more frequently, and this behavior is related to increased copy-cat intentions.
Impact on Voltage Stability Conditions under Inadequate Voltage Control Actions
Authors: Cuaresma Zevallos Oscar , Pimentel Teixeira Marcos Vinicius , Prada Ricardo Bernardo 
Published: April 2017

Abstract
Inadequate voltage control occurs when the controlling variable and controlled voltage of a control device are inversely related (i. e., not related in the usual way), potentially adversely affecting the system voltage level. This special situation can be identified by analyzing the elements of a sensitivity matrix constructed to show the relationship between the system control variables. Analysis of these elements not only allows the adequacy or otherwise of voltage control actions to be determined, but also helps to identify any conflict between controls that could, if not addressed, limit the possibilities for voltage control in the system. Furthermore, once the problem of the inadequacy of voltage control actions for a particular operating point has been identified, its impact on voltage stability conditions can be determined by calculating assessment indexes.

Abstract

Objectives
Evaluating the cost effectiveness and cost utility of an integrated care intervention and participatory workplace intervention for workers with rheumatoid arthritis (RA) to improve their work productivity.

Methods
Twelve month follow-up economic evaluation alongside a randomized controlled trial (RCT) within specialized rheumatology treatment centers. Adults diagnosed with RA between 18-64 years, in a paid job for at least eight hours per week, experiencing minor difficulties in work functioning were randomized to the intervention (n = 75) or the care-as-usual (CAU) group (n = 75). Effect outcomes were productivity and quality of life (QA-LYs). Costs associated with healthcare, patient and family, productivity, and intervention were calculated from a societal perspective. Cost effectiveness and cost utility were assessed to indicate the incremental costs and benefits per additional unit of effect. Subgroup and sensitivity analyses evaluated the robustness of the findings.

Results
At-work productivity loss was about 4.6 hours in the intervention group and 3.5 hours in the care as usual (CAU) group per two weeks. Differences in QALY were negligible; 0.77 for the CAU group and 0.74 for the intervention group. In total, average costs after twelve months follow-up were highest in the intervention group (€ 7,437.76) compared to the CAU group (€, 758.23). The cost-effectiveness and cost-utility analyses show that the intervention was less effective and (often) more expensive when compared to CAU. Sensitivity analyses supported these findings.

Discussion
The integrated care intervention and participatory workplace intervention for workers with RA provides gains neither in productivity at the workplace nor in quality of life. These results do not justify the additional costs.

Authors: Aaberg Kari Modalsli , Gunnes Nina , Bakken Inger Johanne , Lund Søraas Camilla , Berntsen Aleksander , Magnus Per , Lossius Morten I. , Stoltenberg Camilla , Chin Richard , Surén Pål 
Published: April 2017

BACKGROUND AND OBJECTIVES:
Epilepsy affects 0.5% to 1% of children and is the most frequent chronic neurologic condition in childhood. Incidence rates appear to be declining in high-income countries. The validity of epilepsy diagnoses from different data sources varies, and contemporary population-based incidence studies are needed.

METHODS:
The study was based on the Norwegian Mother and Child Cohort Study. Potential epilepsy cases were identified through registry linkages and parental questionnaires. Cases were validated through medical record reviews and telephone interviews of parents.

RESULTS:
The study population included 112 744 children aged 3 to 13 years (mean 7.4 years) at end of registry follow-up (December 31, 2012). Of these, 896 had registry recordings and/or questionnaire reports of epilepsy. After validation, 587 (66%) met the criteria for an epilepsy diagnosis. The incidence rate of epilepsy was 144 per 100 000 person-years in the first year of life and 58 per 100 000 for ages 1 to 10 years. The cumulative incidence of epilepsy was 0.66% at age 10 years, with 0.62% having active epilepsy. The 309 children (34%) with erroneous reports of epilepsy from the registry and/or the questionnaires had mostly been evaluated for nonepileptic paroxysmal events, or they had undergone electroencephalography examinations because of other developmental or neurocognitive difficulties.

CONCLUSIONS:
Approximately 1 out of 150 children is diagnosed with epilepsy during the first 10 years of life, with the highest incidence rate observed during infancy. Validation of epilepsy diagnoses in administrative data and cohort studies is crucial because reported diagnoses may not meet diagnostic criteria for epilepsy.
Why a Philosophy Teacher Would Use Liberal Education Teaching Methods? A Regional College Case
Authors: Vorobyeva Mariya , Kochukhova Elena 
Published: April 2017

Philosophy teachers go about their daily routine in a controversial field created by their personal ideas about education quality, topic planning, and the optimal number of hours overlapping with the education standard requirement for developing general cultural competence in students within a general philosophy course. In a situation like this, the issue of choosing specific teaching methods becomes that of complying with professional standards, of being satisfied with the job done, and of private time. The article attempts to problematize the possibility of integrating writing and analytical reading methods borrowed from liberal education into the educational process of a regional college. Sharing the idea of liberal education advocates that applying these methods to university courses facilitates the development of competencies required by the standard, we analyze our own relevant classroom experience. The paper justifies the effectiveness of teaching methods that develop academic writing and reading skills, arguing that they provide the basis for working independently with educational texts, writing essays, term papers and graduation theses. The most essential hindrances to integrating the above mentioned methods include teacher and student avoidance, as well as regulatory and financial constraints. Syllabus limitations challenge efficiency of the methods for the development of competencies required by the standard. At the same time, the writing and analytical reading methodology is in line with the publicly expressed desire of teachers to organize philosophy seminars without diluting the content. The prospects of large-scale implementation of writing and analytical reading methods in teaching philosophy imply adjustment of the existing syllabi.
The specifics of security in territorial units of the Slovak Republic
Authors: Pavlenko Tomas , Mitasova Veronika , Havko Jan 
Published: April 2017

The development of society is being affected by a range of potential risks and threats. The very existence of these threats negatively influences the level of safety as well as the sustainable development of society. Given that security is one of the fundamental building blocks of civilization for citizens, social groups, states and the overall international community, it is vital to eliminate such threats. This paper focuses on the specifics of security in the territorial units of the Slovak Republic. Regional safety is affected by several factors and activities carried out within a region. A spatial plan is developed for the purpose of permanent harmonization of ongoing activities in a region. This plan, being the fundamental strategic document of an area, does not sufficiently incorporate the issue of security or its improvement; thus, it does not include preventive measures in it. Bearing the above-stated in mind, this paper first points out developing tendencies in the area of security within the Slovak Republic and further identifies the potential and real risks and threats directly affecting the citizens living in the regions. The principal focus of the paper is to describe and define the concept of the activities needed to design territorial planning documents, while at the same time maintaining an active role in minimizing the threats and risks in a selected territorial unit.

“Red-Yellow-Green”
Authors: Okike Kanu , Pollak Rachael , O’Toole Robert V. , Pollak Andrew N. 
Published: April 2017

Background:
Orthopaedic procedures are expensive, and devices account for a large proportion of the overall costs. Hospitals have employed a variety of strategies to decrease implant costs, but many center on restricting surgeon choice. At our institution, we developed an implant selection tool that guides surgeons toward more cost-effective implants, while minimally restricting choice. The purpose of this study was to assess the effect of this tool on preferred implant usage rates, vendor attitudes toward pricing structure, and hospital implant expenditures.

Methods:
For 6 commonly used orthopaedic trauma devices, similar constructs were created for the 4 vendors used at our hospital, and the costs were determined. On the basis of these costs, the available options for each device type were categorized as “green” (preferred vendor), “yellow” (midrange), or “red” (used for patient-specific requirements). The “Red-Yellow-Green” chart was posted on the wall of each orthopaedic trauma operating room. To assess the effect of the tool, we compared implant usage patterns before and after implementation of the implant selection tool. We also assessed changes in vendor contract prices, as well as overall savings to our institution.

Results:
Implant usage changed significantly from 30% “red,” 56% “yellow,” and 14% “green” prior to the intervention, to 9% “red,” 21% “yellow,” and 70% “green” after the intervention (p < 0.0001). As a result of price renegotiation with vendors following implementation, we observed average price decreases that ranged from 1.1% to 22.4%. Average expenditures on these 6 implants decreased 20% during the study period, which represented a savings of $216,495 per year.

Conclusions:
At our institution, we designed and implemented “Red-Yellow-Green,” a simple tool that guides surgeons toward the selection of lower-cost implants without violating vendor confidentiality clauses, limiting the implants from which surgeons can choose, or requiring surgeons to discern the prices of complex constructs. Following implementation, hospital implant expenditures decreased as a result of a combination of increased preferred vendor usage by surgeons, as well as increased competition among vendors, which resulted in lower overall prices.
Comments: Turning a Corner
Authors: Donnelly John 
Published: April 2017

Editor's column
The 2-year downturn in oil prices has been a challenge for operators and service companies alike, but operators appear to have turned a corner, going by the most recent fourth-quarter earnings. For the larger service providers, it may take longer to gain solid financial footing, but the chief executives of these firms are sounding more optimistic.
After months of cost cutting and reassessment of projects, earnings for the larger majors were positive. More stable oil prices and OPEC’s recent production agreement point to a brighter year in 2017. Total boasted a USD 548 million profit for the quarter, compared with a USD 1.6 billion loss in the fourth quarter of 2016. The company announced that it was ready to embark on new projects, possible acquisition, and increased production. BP eked out a USD 72 million profit compared with a USD 2.2 billion loss in the year-ago period. Shell also reported profits, although net revenue was down from the previous year’s quarter. Shell said it had “turned a corner” after paying down debt and absorbing BG. Chevron posted its second straight quarterly profit and sees production growth this year amid cautious spending and cost control. ExxonMobil, meanwhile, recorded its lowest earnings in 2 decades and took a huge writedown on the value of some of its upstream assets.
Smaller operators, particularly those involved in shale plays in west Texas, New Mexico, and other promising areas, plan more aggressive upstream spending this year. While many larger international plays still seem risky, activity in places such as the Permian Basin is soaring.
Service companies are also seeing a better year compared with the previous two, particularly for those involved in North American operations, but still face some challenges. Many service providers have begun renegotiating prices with clients, after slashing prices the past 2 years because of the steep fall in oil prices. “The direction [service companies] all need to go is that we need to recover some of the pricing concessions that we’ve given,” Schlumberger Chief Executive Officer Paal Kibsgaard told the Wall Street Journal during an earnings presentation.

Industry Finding Solutions Through Use of Data Analytics
Trent Jacobs, JPT Digital Editor
As big data analytics becomes more intertwined with the operations of some of the biggest names in upstream, this tech space is beginning to deliver the industry some compelling applications. The most recent data were highlighted in a discussion led by Satyam Priyadarshy, Halliburton’s chief data scientist, who declared that big data analytics “will transform the industry.”
That transformation is to be realized by using analytics to identify and eliminate hidden inefficiencies. According to Priyadarshy, that means that solving known problems is not enough; to achieve a higher order of innovation, oil and gas companies must discover and answer problems they never knew about in the first place.

Renewable Energy Tech is Now Priced To Reduce Upstream Spending
Trent Jacobs, JPT Digital Editor
Could it be that the upstream industry has an unlikely ally in renewable energy? The two sectors are often framed as being at odds—one is supposed to eventually replace the other, after all. But in the meantime, the falling price of renewable technologies has opened the door for oil and gas companies to reduce the cost of electrifying their fields, according to one US energy expert.
“In many locations, solar and wind are now cost-competitive with other forms of electricity generation, so it just makes economic sense to be incorporating them into your industrial operations.” said Jill Engel-Cox, the deputy director of the US Joint Institute for Strategic Energy Analysis (JISEA).

Fossil Fuels Importance To Rise Under New US Administration

Fossil fuels will probably be at the fore-front of energy and environmental policy under the new Trump Administration, said Charles D. McConnell, executive director of Rice University’s Energy and Environment Initiative, in a recent talk hosted by the Norwegian Consulate General in Houston.
McConnell served 2 years as an assistant Secretary of Energy in the Obama Administration before taking his current position. He has spent 35 years in the energy industry, which includes a 31-year career at Praxair followed by serving as a vice president at Battelle Energy Technology.
Succeeding in the Shale Business With a Lean Well Manufacturing Management System
Authors: Bossi Carlos 
Published: April 2017

Management
The current oil and gas commodity prices have posed several challenges to oil and gas companies operating in shale plays trying to generate revenue or even becoming cash neutral. Shale drilling, as opposed to conventional drilling, requires many more wells to produce similar volumes of oil or gas due to the significantly smaller wellbore drainage area and the tight nature of the reservoir. For these projects to be economically viable, a high volume of low-cost and quickly drilled and completed wells is required, which cannot be achieved with a conventional oil and gas mindset.
By implementing a Lean Well Manufacturing Management System and by having a dedicated Productivity Improvement team embedded in the operations driving changes, BHP Billiton was able to reduce drilling and completion (D&C) costs by 49% in the Eagle Ford Basin and 50% in the Permian Basin over an 18-month period (Fig. 1). These results are similar to those reported by other operators in similar plays that also incorporated lean management principles to their operations.
A Lean Well Manufacturing Management System can be defined as a system to drill and complete a large number of wells per year in a factory-like setting using a lean manufacturing mind-set. The performance of the “factory” is measured by the ability to deliver wells at low capital costs while still performing safely, reliably, and meeting local regulatory requirements.
To be successful, this model requires predictable and repeatable performance using highly dependable and fit-for-purpose equipment that is easy to operate and maintain. Value is maximized by addressing the technical specifications from the customer and optimizing the use of existing and new technology to realize the lowest achievable well cost. In turn, this translates into reduction of the unit development costs, increase in short-term production, and more efficient resource utilization.
Waste can be encountered in many areas in the well delivery process, which can increase D&C costs, jeopardizing the project economics. For this reason, the key objective for a lean organization is to identify areas where waste needs to be reduced and eliminated without compromising safety, quality, and performance using the resources (people), processes, and technology available.
Key Learnings From First 2 Years of a Full-Field CSS Development in Oman
Authors: Wilson Adam 
Published: April 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 179833, “Key Learnings From First 2 Years of a Full-Field CSS Development in Oman,” by Solenn Bettembourg, Steve Holyoak, Abdullah Alwazeer, Mohammed Manhali, Mohammed Rawahi, and Amur Habsi, Petroleum Development Oman, prepared for the 2016 SPE EOR Conference at Oil and Gas West Asia, Muscat, Oman, 21–23 March. The paper has not been peer reviewed.
The A East Haradh formation contains a 200-m-thick oil column of highly viscous oil, with viscosity ranging from 200 to 400,000 cp. Because of the high viscosity, first production was considered possible only by the use of thermal enhanced-oil-recovery techniques, starting with cyclic steam stimulation (CSS). This paper presents key learnings derived during this initial-operations phase of CSS in the A East Field, including key trial results on different well completions and artificial-lift systems.
Overview of Field Startup
In light of the results of a new geochemical characterization study of the crude extracted from a core, cold production was deemed feasible in the crestal area of the field. Viscosities at the top of the Haradh were estimated at 200 cp, lower than previously thought, and progressing cavity pumps (PCPs) were installed in 32 wells to start a cold-production phase.
Cold production started in March 2013 and lasted until the end of 2014, when all wells in the field were converted to CSS. The cold-production period allowed early depletion of the reservoir and later improvement in steam injection. A pressure drop of up to 20 bar was observed, and fluid-level measurement in the wells and PCP performance suggested good pressure communication between the wells.
Despite some early challenges, first CSS production was promising and, within a few months, was ramped up to 70% of the targeted CSS field peak oil rates.
Overview of CSS Performance
A typical CSS cycle in an A East well is shown in Fig. 1, using the wellhead temperature sensor as an indicator. The cycle starts with the injection phase for several weeks (initially 4 to 6). After that, the well is closed for a soaking period of a few days and then opened for free flow, which lasts for up to 3 weeks. The well is intervened with a flush-by unit (FBU) to prepare for production, followed by starting the beam pump. At the end of the production cycle, the well is stopped on the basis of end-of-cycle criteria and intervened again to prepare the well for steam injection for the subsequent cycle. The overall cycle duration is typically between 100 and 300 days and is dependent on the performance of the well with respect to preset operating envelopes.
Hybrid EOR Technology: Carbonated Water-Smart Water Flood Improved Recovery in Oil Wet Carbonate Formation: Part-II
Authors: Kilybay Alibi , Ghosh Bisweswar , Thomas Nithin Chacko , Sulemana Nuhu Turosung 
Published: April 2017

Abstract
Search for an alternative, cheap and environmental friendly EOR method has resulted in the development and subsequent field implementation of Smart Water Injection (SWI) and CO2 injection (COI). Though miscible COI has multi-fold advantages, carbonated water injection (CWI) may surpass COI in terms of volume requirement and efficiency. This research work is intended to investigate the advantages of combined application of SWI & CWI in terms of reduced residual saturations in oil wet carbonate formation.
In order to measure the recovery efficiency, core flooding experiments are conducted with SWI as tertiary recovery following sea water as secondary recovery mode. This is followed by quaternary recovery using carbonated smart water (CSWI), i.e. smart water saturated with CO2. Three high potential smart water compositions are screened and the best one is chosen for the recovery studies. Produced water samples are analyzed using ICP-MS. The higher recovery efficiency of CSWI are analyzed in support of the NMR porosity distribution, interfacial tension and zeta-potential studies. The underlying physical processes and the pore-scale mechanisms of fluid-fluid and fluid-solid interactions during SWI-CWI are explained in terms of surface potential, electrical double layer, oil swelling factor, droplet coalescence, wettability alteration and flow diversion due to fluid redistribution within the pore network. Core flooding results showed that tertiary recovery with SWI resulted in 4.8 - 9.5% recovery, whereas the quaternary recovery with CSWI resulted in 5.7 % to 13.6% additional oil.
From this study it is established that CSWI could be a promising EOR technique among the latest EOR methods. CSWI has an advantage over COI due to the fact that it exists as a dissolved gas instead of free phase. It reduces the requirement for high pressure injection system, the problems of gravity segregation and poor sweep efficiency. A hybrid of CWI with SWI can make it an effective EOR solution with significant cost advantage, higher oil recovery in addition to the environmental benefits of CO2 sequestration.
