How far does Twitter deepen democracy through public engagement?: An analysis of journalists’ use of Twitter in the Johannesburg newsroom
Authors: Daniels Glenda 
Published: December 2014

Abstract
The use of social media, mainly Twitter, in the Johannesburg newsroom presents an opportunity for the opening up of media spaces to public engagement, thereby deepening democracy. This article, framed through radical democratic theory, is a scrutiny of journalists’ use of Twitter. The article deploys multidimensional methods against a theoretical conceptual approach. It uses a content analysis of Twitter feeds, discourse analysis, as well as interviews with journalists and editors to reach some reflective insights. The issues include the following: there is much ‘noise’ about, and within, Twitter in the newsroom but does this robust public engagement engage more voices, and therefore diversity, into the public sphere of journalism? Or could the world of Twitter in the newsroom, at this present moment, exist as a mainly consensus seeking one – that of the like-minded merely re-affirming each other’s views? The argument here, which is open for debate, is that Twitter presents an opportunity to deepen democracy, but at this moment it is limited, as the data gathered from newsrooms in Johannesburg show.
‘Charlotte makes me lafe [sic] sooo much’: Online laughter, affect, and femininity in Geordie Shore
Authors: Graefer Anne 
Published: December 2014

Abstract
Highly successful structured reality television shows such as Geordie Shore (UK), The Only Way is Essex (UK), Made in Chelsea (UK) or Jersey Shore (US) draw audiences wide beyond their regional and national appeal, thereby exerting a considerable influence on contemporary popular culture. Lying at the intersection of documentary, soap opera and drama, reality television’s specific form – its immediacy and its emotionality – invites viewers to judge and moralize the lives depicted on screen. In this article I explore the affective ways in which ‘Geordie Shore’ produces ideas about femininity and how comic moments in the show influence this emotive process. By analysing online comments on the show’s official Facebook page I argue that the humorous quality of the text does not merely reinforce the disciplining white, middle-class gaze through which ‘Geordie’ femininities are produced as hypersexual(ized) ladettes worthy of social derision. Rather, the online laughter that I found in some online comments highlights that these representations are also animated through feelings of joy, affection and emotional attachment. Attending to online laughter can help us to further understand the movement between connection and disassociation through which audiences make sense of reality television.
M is for mother: Skyfall’s Kleinian phantasies of maternal destruction
Authors: O’Donnell Ruth 
Published: December 2014

Abstract
In the Bond film Skyfall (2012), director Sam Mendes offers an interpretation of gothic horror that explores 007’s maternal ambivalence. Exploiting the genre’s tropes of the persecutory double, psychotic son, and monstrous feminine/mother, the film provides a ‘working through’ of the oedipal terror that is so redolent of the gothic. Taking as a reference point the work of Freudian theorist Melanie Klein, Skyfall can be seen as presenting ‘M’ (Judi Dench) as the Kleinian ‘bad mother’, one half of the ‘split’ that the infant conceptualizes to explain the inadequacy of the mother in meeting his needs, phantasizing his revenge in terms of oral aggression. Bond (Daniel Craig) and villain Silva (Javier Bardem) are each victims of exploitation by the British secret services – and by extension the figural mother M. For Silva this means being given up to the Chinese government for torture and likely death. It is this previous act of maternal mistreatment that serves to ‘explain’ his (sexual) perversity, i.e. renunciation of the phallic, which includes his perverse attachment to M (other). Silva serves as 007’s shadowy counterpart – as well as cautionary tale – in granting the phantastical wish-fulfilment of both sons: revenge upon the mother.
‘I Can Have Both’: A queer reading of Morrissey
Authors: Dillane Aileen , Power Martin J. , Devereux Eoin 
Published: December 2014

Abstract
Using the song ‘I Can Have Both’ as a case study, we examine the ways in which Morrissey’s creative output has consistently recognized the fluidity of sexual and gender identities. We demonstrate how Morrissey’s work invites a deep textual reading that reveals a complex counter-hegemonic stance on the issue of gender and sexuality. Queering and queer discourses play a fundamental role in achieving this. Our study adds to the emerging body of scholarly literature on Morrissey and contributes to our understanding of how queering processes occur within a popular culture setting.
A Neumann problem involving the p(x)-Laplacian with
p = ∞ in a subdomain
Authors: Karagiorgos Yiannis , Yannakakis Nikos 
Published: December 2014

Abstract
In this paper we study a Neumann problem with non-homogeneous
boundary condition, where the p(x)-Laplacian is involved and p = ∞
in a subdomain. By considering a suitable sequence pk
of bounded
variable exponents such that pk
→ p and replacing p with pk

in the original problem, we prove the existence of a solution uk
for each
of those intermediate ones. We show that the limit of (uk
) exists and
after giving a variational characterization of it in the part of the domain
where p is bounded, we show that it is a viscosity solution in the part
where p = ∞. Finally, we formulate the problem of which this
limit function is a solution in the viscosity sense.
Extended Unemployment Insurance and Job Search: Evidence from Time Use Data
Authors: Regmi Krishna 
Published: December 2014

Abstract
In this paper, I investigate the effect of extended unemployment insurance (UI) coverage in the United States in recent years on job search. The U.S. government extended UI benefits in several phases in 2008–2009, increasing the duration of the benefits to a maximum of 99 weeks, up from the regular 26 weeks. Using the American Time Use Survey (ATUS) data, I find that women are more sensitive to the extended UI benefits than men. Difference-in-differences estimation shows that the average effect of the UI extensions for women is over a 10 percentage points decline in the probability of job search. However, I do not find any statistically significant effect on men.
How Close Is a Fractional Process to a Random Walk with Drift?
Authors: Larsson Rolf 
Published: December 2014

AbstractIn this paper, we investigate how close a fractional process can be to a random walk with drift in terms of the sample path. Given the innovation sequence, we calculate the distance to the closest random walk with drift in the sum of squares sense. We also derive the expected distance between the processes under the assumption of white noise normal innovations. A local approximation formula for this distance is given in terms of the sample size, showing that it increases with the sample size more rapidly than the square of the number of observations. Two empirical examples illustrate the results.

Published: December 2014

Background: Although patients with diabetes are frequently affected by periodontitis, only a few investigations have focused on gingivitis in this at‐risk population. This randomized placebo‐controlled clinical trial compared the response to a gingivitis treatment protocol that combined mechanical procedures and daily use of an essential oil (EO) mouthrinse between patients with and without diabetes.Methods: The whole‐mouth periodontal probing depth (PD), gingival index (GI), and plaque index (PI) were monitored in gingivitis cases among systemically healthy patients (n = 60) or those with diabetes (n = 60) at baseline and 3 months after treatment. Levels of Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, and total bacterial load were determined by a real‐time polymerase chain reaction in intrasulci plaque samples. The volume of gingival crevicular fluid (GCF) was quantified, and interleukin‐1β (IL‐1β) levels were determined in GCF samples. After a full‐mouth ultrasonic debridement, patients were randomly assigned to an EO or a placebo rinse for 90 days (40 mL/day). The data were analyzed through repeated‐measures analysis of variance and multiple comparisons Tukey tests (P <0.05).Results: GI was more severe in the diabetes group. Diabetes impaired GI and reduced GCF volume. PD, bacterial levels, and IL‐1β improved similarly in both systemic conditions. The adjunctive use of EO provided greater reductions of PI, GI, total bacterial load, T. forsythia, A. actinomycetemcomitans, and GCF volume.Conclusions: Response to gingivitis treatment in patients with diabetes can slightly differ from that in patients without diabetes. Daily use of an EO mouthrinse after ultrasonic debridement benefited patients with and without diabetes.

Published: December 2014

Case:A sixteen-year-old professional soccer player presented with persistent pain in the right thigh of two years’ duration and the inability to return to play. Evaluation revealed a chronic rupture of the rectus femoris muscle. Because physiotherapy and rehabilitation failed to help, a surgical repair was performed. He returned to his previous activity level within nine months after surgery.Conclusion:Rupture of the proximal part of the rectus femoris should be acknowledged in the differential diagnosis, especially when presenting with persistent pain in the anterior aspect of the thigh lasting more than one year. Delayed repair might be recognized as a reasonable option for chronic rupture of the proximal part of the rectus femoris.
Chemical and Mechanical Aspects of Wellbore Stability in Shale Formations: A Literature Review

Published: December 2014

Abstract
Drilling a shale formation with no borehole problems can be a challenging task. With high content of clays, shale formations are prone to swelling, dispersion, tight hole and other problems. Those problems are well-documented in literature. Different types of clays give different types of problems. For example, when it is exposed to water, a shale sample with a high percentage of smectite tends to swell while another shale sample with a high percentage of kaolinite tends to disintegrate and disperse. The mechanism that destabilizes reactive shale when it comes in contact with water differs from on shale sample to another. It is important to know which mechanism is taking place in order to be proactive and inhibit the drilling fluid with the appropriate inhibitor. It is also important to characterize the shale sample in terms of its geological structure, mineralogical composition and interaction potential.
Shale characterization and testing methods include but not limited to the following: X-ray analysis, degradation and reorientation evaluation using scanning electron microscope (SEM), cation exchange capacity (CEC) determination, swelling test, dispersion test, slake durability test, bulk hardness test, accretion test, shale membrane test, inhibition durability test and uniaxial and triaxial compression tests.
Different types of shale inhibitors and stabilizers have been used in the industry such as: potassium chloride, calcium chloride, silicates, polyamines, glycol and lignosulfonate. Each of them has a mechanism by which it can inhibit the hydration, disintegration and dispersion of clays in the presence of water.
This paper discusses the physio-chemical and chemico-mechanical effects of shale-drilling fluid interactions and the associated drilling problems that are most frequently encountered while drilling shales formations. It also reviews the most common shale testing methods used to evaluate the interaction potential of various shale-drilling fluid systems. Moreover, the paper describes different mechanisms by which shale can be inhibited and wellbore stability problems can be mitigated.
Multi-Lateral Well Design Advisory System; an Inverse-Looking Solution
Authors: Al-Mousa Talal S. 
Published: December 2014

Abstract
The shifting trend towards drilling multilateral wells has motivated engineers and researchers to investigate ways to improve their decision-making when designing multilaterals. The problem becomes more challenging in unconventional reservoirs, where tighter and highly heterogeneous and discontinuous reservoirs are targeted. Achieving the right design of a multilateral well configuration is a complex problem due to the vast possibilities of well forms (i.e., number, location, length and orientation of laterals) that need to be evaluated. Accordingly, arises the need for an inverse-looking approach to come up with a sound decision.
Conventional ways in designing multilaterals involves investigation of different possible scenarios using a reservoir simulator model and comparing results against an objective function. However this addresses the problem only from a forward-looking point of view. This procedure is time and labor intensive and tremendously increases the computational cost. This paper illustrates the utilization of the artificial neural network (ANN) concept to develop an advisory system for designing multi-lateral well configurations for a given target reservoir performance in fraction of the time, cost and effort required by a numerical simulator. From that point onwards an engineer can improve on the recommended design or modify it to adhere to certain field, cost or operational constraints.
Reservoir Connate Water Chemical Composition Variations Effect on Low-Salinity Waterflooding
Authors: Shehata Ahmed M. , Nasr-El-Din Hisham A. 
Published: December 2014

Abstract
Extensive experimental work has indicated that Low-Salinity Waterflooding (LSW) is an enhanced oil recovery technique that improves oil recovery by lowering and optimizing the salinity of that injected water. Most of the LSW studies focused on the injection of brine salinity and composition. The question remains how does the salinity and composition of reservoir connate water affects the LSW performance. Therefore, in this paper different connate water compositions were used (TDS varies from 1550 up to 174156 ppm) to investigate the role of reservoir connate water on the performance of LSW.
Nine Spontaneous Imbibition (SI) experiments and six coreflood experiments were performed. Two sandstone types (Bandera and Buff Berea) with different clays contents and stock-tank crude oil samples were used in all the experiments. This work describes experimental studies of SI of oil by low-salinity and high salinity brines using 20″ long outcrop sandstone samples. This study focused on the effect of connate water composition and temperature, 77 and 160°F, on the performance of LSW. The coreflood experiments have been conducted using 6 in. outcrop Buff Berea sandstone cores at 150°F and 500 psi. Oil recovery and pressure drop were observed and analyzed after each coreflooding experiment to examine the effect of the connate water composition (Na+, Ca+2, and Mg+2) on the performance of the LSW in secondary recovery mode.
Reservoir connate water composition and salinity have a dominant influence on the oil recovery rate. The Ca2+, Mg2+, and Na+ ions play a key role in oil mobilization in different sandstone rocks. Reservoir cores saturated with connate water contained divalent cations of Ca+2 and Mg+2 showed higher oil recovery for cores saturated with monovalent cations Na+. Low-salinity waterflooding showed a high potential to improve oil recovery in the SI experiments at different temperature levels. For high permeability Buff Berea cores, the SI oil recovery ranged from 38 to 69% OOIP, while oil recovery of the low permeability Bandera cores ranged from 17 to 45% OOIP at 77°F and 14.7 psia. As the temperature increased from 77 to 160°F, an additional oil recovery up to 4.2% of OOIP was observed by SI for Buff Berea cores. From the coreflood experiments, low-salinity brine had a significant positive effect on oil recovery for sandstone cores saturated with divalent cations (Ca+2 and Mg+2). The magnitude of incremental oil recovery increased from 51.9 to 58.9% OOIP when the reservoir connate water salinity increased from 3,420 to 36,350 ppm. On the other hand, increasing the monovalent cations (Na+) from 1,550 to 137,670 ppm resulted in slight increase in oil recovery (1.2% OOIP). The oil recovery from the coreflood runs for the Buff Berea cores ranged from 58.9 to 35.9% OOIP. The oil recovery decreased when the salinity of reservoir connate water decreased.
New Approach for Formation Evaluation Using Advanced Mud Gas Analysis of Conventional and Unconventional Reservoirs: A Case Study from Onshore UAE

Published: December 2014

Abstract
The formation evaluation of any wildcat, exploratory and/or appraisal well is challenging due to scarcity of information with respect to reservoir presence, its characterization and the expected pressure. It is expected that hydrocarbon bearing reservoirs, especially those located in low resistivity zones and without core for calibration of physical properties, might possibly be overlooked as these are difficult to interpret from petrophysical logs for the presence or absence of hydrocarbons.
An advanced surface mud gas acquisition and analysis system, based on membrane technology, was utilized for the first time in the United Arab Emirates. Advanced mud gas analysis and interpretation of conventional and unconventional carbonate reservoirs sections identified interesting hydrocarbon bearing zones which were subsequently confirmed by integration of core, electric log and well-test data.
An exploratory well was drilled to explore the hydrocarbon potential of unconventional reservoirs and appraise the conventional carbonate reservoir. Reliable results were achieved in a highly challenging environment including petrophysical uncertainty and a variety of reservoir fluids present. The results from the advanced mud gas analysis were confirmed by down hole sample testing results.
The approach developed can be modified or customized to explore/appraise a prospect to capture any hydrocarbon zones, including by-passed zones, and subsequently optimize logging and testing programs resulting in a reliable data set and cost savings.

Abstract
The first deepwater well in the Saudi Arabian side of the Red Sea was going to be a rank wildcat well. Saudi Aramco Upstream leadership assembled a team of experienced, knowledgeable and dedicated professional staff across the Exploration Geology, Geophysics, Reservoir and Exploration Drilling organization to undertake the challenge of safe and successful well delivery. Contemporary frontier exploration projects utilize project development processes with long inter-nodal phasing schemes that follow traditional lateral cascade workflow methodology or the common waterfall process.
Published works on project development best practices cite project development and management processes that are ostensibly an adoption of product development processes with stage gates and decision points. In order to meet the Saudi Aramco leadership challenge for project delivery -- speed, scale and a safe delivery mandate, non-negotiable parameters established for the project -- innovative project interface management tools and strategies devised to enable multidisciplinary resources both internal and external to recognize vertical and lateral impacts of decision, specification and system dependencies, compatibility, boundaries and critical path sensitivities was developed.
The pervasive cohesion and shared sense of responsibility by the core project team and service partners, seamless communication protocols among stakeholders though fraught with complex and diverse perspectives was also a source of robust decision making. Several industry first technologies for well construction were successfully deployed and the meticulous engineering motions undertaken to ensure hitch-free deployment are noteworthy. The strategies for selection of service contractors along service and product lines, capabilities and compatibility for performance management are also described.
This paper describes drilling engineering and operations preparation, front end engineering and design activities, and the project delivery success of Saudi Aramco's first deepwater exploration program in the Red Sea. The validation of the potency of the strategies, tools and systems employed is embodied in the drilling to record regional total depth of the first deepwater well of Saudi Aramco's Red Sea Deepwater Exploration Campaign Program
