Socio-spatial distribution of urban residents in a small-sized city
Authors: Alkay Elif , Kaya Hasan Serdar 
Published: November 2018

Purpose
This study aims to explore the pattern of urban residents’ socio-spatial distribution in a small-sized city where the local housing market capacity and variety is limited.

Design/methodology/approach
Spatial variation was reflected by two different analysis. First, factor analysis was applied to determine the major dimensions of the social, economic and housing environment in the investigation area. Second, Kriging maps, which depict the socio-spatial distribution pattern of the households according to major dimensions, were produced by interpolating factor scores on a continuous surface. Those were supported by complementary exploratory analysis to deepen the discussion.

Findings
Homogenous distribution of similar groups to housing areas and low inner differentiation particularly within lower income neighborhoods are the noticeable results of the analysis set. Ethnicity and income differentiation are the principal determinants of socio-spatial distribution pattern in our case. The constraints of the local housing market are seemed to facilitate spatial separation. Disadvantaged population groups are limited to small niches within the urban fabric; they are relegated to poor quality neighborhoods or to unpopular inner-city housing estates.

Research limitations/implications
This research has been performed for the small size city in Turkey and may not hold for other areas, even though the methodology can be replicated and the mechanisms at play are quite similar elsewhere.

Practical implications
The internal differentiation of urban residents’ is worth investigation to develop consistent housing and planning policies to overcome prospective social exclusion problems. This study has a potential of remarking the importance of policy-based economic and housing development in smaller cities in Turkey.

Social implications
Analyses displayed a sectoral structure of the distribution of urban residents but lower inner differentiation within neighborhoods. Limitations of the housing stock facilitate substantial level of isolation to the extent of ethnicity. Two different ethnic groups are confined to small niches, and they are ethnically and economically tied down to their neighborhoods. The physical properties and the quality of both dwellings and the housing environment are the poorest in these areas, and these are unpopular housing areas by the majority of the population. These findings are supposed to give direction of setting consistent housing policies in the case area.

Originality/value
This research is one of the initial research on socio-spatial distribution of urban residents to housing areas in Turkey. It is also one of the rare examples of socio-spatial differentiation study in small-sized city in the literature. The authors have shown that socio-spatial differentiation would be severe even in small size housing markets as opposed to expectation.
Parent brands’ influence on co-brand’s perception: a model-based approach
Authors: Böger Daniel , Kottemann Pascal , Decker Reinhold 
Published: November 2018

Purpose
This paper aims to investigate what influence the perceptions of two parent brands have on the perception of a newly formed co-brand. Furthermore, it elaborates whether respondents’ evaluations of the parent brands, their familiarity towards the parent brands and their usage of the parent brands affect this influence.

Design/methodology/approach
Building on both cognitive consistency and information integration theory, this paper proposes a model-based approach to quantify the parent brands’ influence on the co-brand’s perception. Using an empirical study with 317 respondents collected by a professional online market research firm, this paper highlights the benefits of this model-based approach.

Findings
The results indicate that the perception of a co-brand arises from a weighted merge of the parent brands’ perceptions. The findings further reveal that the better (worse) a parent brand’s evaluation is in contrast to the other parent brand’s evaluation, the more (less) familiar a parent brand is in contrast to the other parent brand, and the more (less) frequent a parent brand is used in contrast to the other parent brand, the larger (smaller) is its influence on the co-brand’s perception.

Originality/value
The findings shed light on the formation of a co-brand’s perception which can be crucial when selecting the right co-branding partner. Additionally, by quantifying the parent brands’ influence on the perception of the co-brand, this model-based approach helps brand managers to analyze co-brand pairings beforehand and select the best pairing in accordance with their goals.
Integrating methods for the prioritization of innovations and improvements in services
Authors: Picolo Jaime Dagostim , Tontini Gérson 
Published: November 2018

Purpose
This paper aims to present a methodology for the prioritization of innovations and improvements in services and products that integrates penalty–reward contrast analysis (PRCA) and improvement gap analysis (IGA).

Design/methodology/approach
The presented method is theoretically developed and simulated. It uses a case study with 290 clients of supermarkets, evaluating 16 attributes of this service, to demonstrate the advantages of integrating PRCA and IGA.

Findings
The integration of PRCA and IGA provides benefits that outweigh the use of each method individually. The joint use of these methods allows the identification of possible nonlinear impact of attributes on customers’ overall satisfaction, allowing managerial recommendations to be made with greater discriminatory power, in addition to qualifying the identification of innovative attributes.

Originality/value
Managers must be aware of the effect of the interaction of innovative attributes with attributes already used by the company. At the same time, it is appropriate to verify whether there is potential to improve the existing attributes. The literature shows that PRCA identifies the nonlinear influence of customers’ satisfaction with individual attributes on overall satisfaction, but it fails to identify the possible impact of innovative attributes. In turn, IGA identifies innovative attributes but does not identify how the attributes influence overall satisfaction. Thus, the benefits of integrating PRCA and IGA outweigh the individual limitations of each method, thereby increasing the quality of managerial recommendations. Moreover, a limitation of PRCA makes this method useful for identifying innovative attributes in relation to attractive attributes identified by the IGA method.
Bank capital and liquidity creation: new evidence from a quantile regression approach
Authors: Mazioud Chaabouni Manel , Zouaoui Haykel , Ellouz Nidhal Ziedi 
Published: November 2018

Purpose
The purpose of this paper is to examine the effect of bank capital on liquidity creation. Especially, the authors test two competing hypotheses: the “risk absorption” hypothesis and the “financial fragility-crowding out” hypothesis that describe such association in the context of UK and French banking industry.

Design/methodology/approach
The authors use data collected from Bankscope for commercial banks pertaining to the aforementioned countries. The sample period ranges from 2000 to 2014. Liquidity creation was measured using a novel approach proposed by Berger and Bouwman (2007). This study uses the quantile regression (QR) and the instrumental variables QR, along with classical ordinary least squares (OLS) and panel regression, to deal with the mixed results reported by previous papers.

Findings
Using OLS and panel regression, the authors first find that bank capital negatively affects liquidity creation which supports risk absorption hypothesis. Second, the result from QR confirms the negative association between the aforementioned variables and shows that the effect is homogenous across quantiles of liquidity creation distribution. The result remains unchanged when using the QR with instrumental variables to address the potential problem of endogeneity.

Originality/value
This paper sheds more lights on the relationship between bank capital and liquidity creation by using a novel estimation approach based on the QR methodology.

Authors: Sabapathippillai Saumyarika , Lekamwasam Sarath 
Published: November 2018

AbstractAimFragility hip fracture has become a major global health concern. Data related to recurrent fragility fractures are sparse in the South Asian region.MethodWe assessed the prevalence of prior fragility fracture among patients admitted with new hip fracture to a tertiary care hospital in southern Sri Lanka. Also the incidence of refracture was assessed among hip fracture survivors followed up for 24 months after discharge.ResultsThree hundred and nine patients with incident hip fracture were admitted during the study period (June 2014‐February 2015) and 11 patients died while in the ward. We detected previous fracture in the contralateral hip in eight patients, while two others had distal radius fracture and one patient clinical vertebral fracture (rate = 3.6%). During the follow up two patients developed fractures in the contralateral hip while either clinical vertebral or distal forearm fractures were not detected (refracture rate = 0.004/person years).ConclusionThis analysis based on a regional hip fracture registry shows a low prevalence of prior fracture among patients admitted with incident hip fracture and a low rate of refracture among survivors. More studies are needed to assess whether there are geographical variations in the prevalence of prior fracture or refracture among patients with incident hip fracture.

AbstractObjectivesTo investigate the impact of European Scleroderma Trials and Research (EUSTAR) standardized training on the accuracy of modified Rodnan skin score (mRSS) in patients with systemic sclerosis (SSc).MethodsEight SSc patients (four diffuse, four limited) and 10 physicians (4 fellows, 6 professors) were included. Gold‐standard mRSS was performed by a senior instructor. Training comprised a video presentation and a live demonstration. Each physician performed mRSS with no clinical information in all patients: (a) before training; (b) after video session; and (c) after live demonstration. Primary outcome was the change in scoring accuracy, which was defined as the difference from the gold‐standard skin score, as analyzed using a linear mixed model.ResultsMean (standard deviation) difference from the gold‐standard score in all measurements by participants before the training was 7.7 (9.5). Completion of training significantly enhanced mRSS accuracy (adjusted β = −7.61; 95% CI: −11.91 to −3.32). This was largely attributable to the video presentation (adjusted β = −5.47; −9.16 to −1.78), although the live demonstration was associated with numerical reduction in the difference from the gold‐standard score (adjusted β = −2.15; −5.84 to 1.55). Effect of training was prominent in fellows whereas professors showed an increase in the difference from gold‐standard score after training (P value for interaction <0.001). The intraclass correlation coefficient for physician skin scores was acceptable. However, no significant change was observed after training.ConclusionNew EUSTAR standardized mRSS training significantly enhanced mRSS accuracy, especially in participant with less previous experience in skin scoring.
Meeting the need or falling in line? The effect of laissez‐faire formal leaders on informal leadership

Published: November 2018

AbstractWe consider the utility of two contrasting theoretical perspectives in explaining how laissez‐faire formal leaders and team member motivation to lead (MTL) influences informal leadership and team task performance. The first perspective, functional leadership theory, is the dominant lens used currently to understand informal leadership. However, we suggest that social learning theory offers a compelling alternative account. In a multiwave survey study of 344 members of 72 work teams, we find support for the social learning theory predictions that laissez‐faire formal leaders are perceived by team members to engage in less modeling of effective leadership and as a result are negatively associated with informal leadership and team task performance. We do not find support for the functional leadership theory predictions that laissez‐faire formal leaders are positively associated with team members’ informal leadership and team task performance, which would be due to an increased perceived need for leadership. The social learning effects are stronger for teams that are lower in member MTL and weaker for teams that are higher in member MTL. These results suggest social learning theory may be preferable to functional leadership theory for understanding informal leadership in teams.

Authors: Kamarudin Mohd Khairy , Nor Muhammad Nasrul Hisyam 
Published: November 2018

Hibah through transfer the ownership of land is a regular practice among Muslims in Malaysia. Transfer the ownership of land can be completed in the Land Office by using Form 14A. However, there are many disagreements among the heirs towards the equality of transfer ownership as many cases concerning the validity and the withdrawal of the hibah in court. So the question arises, how the selection of beneficiaries by the grantors for their property. Therefore, the aim of this study is to identify transfer of the land ownership, according to the Land Administrator perspective. This study applies a qualitative approach in which semi-structured interviews with Land Administrator was conducted. The results indicates that parents transfer his/her land to the children as to avoid property is distributed according to the law of inheritance and help their children due to economic constraints.
Program to Evaluate Readiness Levels of Pipeline-Oriented Technologies
Authors: Alexander Chris , Kulkarni Satish 
Published: November 2018

Technology plays a critical role in the oil and gas sector, and the pipeline industry is no exception. Maintaining the integrity of high pressure oil and gas pipeline requires the use of advanced technologies. A challenge that confronts every pipeline operator is the risk posed in the deployment of unproven technologies, especially those associated with the inspection, assessment, monitoring, and rehabilitation of their systems. Use of unproven technologies and concepts puts pipeline operators at risk.
The concept of Technology Readiness Levels (TRLs), commonly used in the aerospace and defense industries, provides the pipeline industry with a proven means for evaluating and assessing technologies used to enhance integrity management efforts. This paper presents details on technology readiness levels ranging from Proof of Concept to System Operation. The adoption and implementation of the TRL approach will minimize operator risk and foster the deployment of advanced technologies, thus enhancing the safe operation of high pressure pipelines. Three TRL-oriented case studies will be included evaluating the monitoring of pipelines using fiber optics, inspection using three-dimensional imaging, and reinforcement using optimized composite technologies.
Combining Expert Knowledge and Automation to Maximize Pipeline Route Optionality and Defensibility: A Case Study of the Aurora Pipeline
Authors: Seel Kevin , Phillips Adam 
Published: November 2018

It has become increasingly difficult to successfully develop pipeline projects in North America. This stems from complex matters including environmental opposition, Indigenous rights, regulatory uncertainty, investor indecision and evolving policy. To manage these challenges, developers are advised to consider a route development methodology that provides both optionality and defensibility. This can be achieved through a process that characterizes the landscape based on level of constraint related to environmental and social factors, construction and operational limitations, strategic drivers and cost. Such a process must be analytically robust and able to adapt to new information and priorities emerging throughout the development phase. Particularly in the case of large-scale pipeline projects, traditional routing methods may prove too costly and time-consuming to undertake this analysis in a practical manner. Consequently, proponents may be left with fewer and less defensible route options.
Recently, the Aurora Pipeline Team sought to advance preliminary corridor routing under a paradigm of maximum optionality and defensibility in evaluating pipeline routes across northern British Columbia, inclusive of strategic interconnections. Implementing Golder Associates Ltd. automated routing decision support system called “GoldSET” the team was able to rapidly perform a robust corridor options analysis covering over 400,000 km2. This systematic, data-driven process involved subject matter expert assessment of the level of constraint or opportunity associated with individual data layers in consideration of multiple, thematic scenarios. Having consolidated and mapped the aggregated level of constraint across northern BC, routes were generated along paths of least constraint with segments tested for agreement across multiple scenarios. In total, 72 routes comprising more than 50,000 km in total length were developed and evaluated for feasibility. This refinement process ultimately resulted in an interconnected network of approximately 180 pre-screened route segments totaling nearly 12,237 km of potential routes. The advantage provided in subsequent stages of the project was the ability to recognize, quantify and evaluate the tradeoffs between segments, and adapt the route as fatal flaws were encountered. During ensuing, constructability-focused phases of the routing process, optionality had been pre-established, and route changes were able to be made quickly where required. The automated process, in companion to subject matter expert participation, also provided a clear and defensible rationale as to why routes were considered optimal, and how potential impacts to sensitive features were addressed. The evaluation was completed in far less time and more cost-effectively than otherwise possible with traditional methods.
Challenges to Repair a Damaged NGL Pipeline by Third Parties in the Andean Mountains Without Stopping Pumping
Authors: Ramos Sandro 
Published: November 2018

One of the challenges of transporting Natural Gas Liquids (NGL) is to ensure that the flow should be delivered with standards of safety, reliability, and efficiency while conducting repairs on the pipeline. This paper discusses the difficulties that had to be overcome to repair a damaged NGL pipeline by third parties performed in the Andean Mountains in Ayacucho, Perú, on NGL pipeline operated by Compañía Operadora de Gas del Amazonas (COGA). This pipeline and a parallel one also operated by (COGA) are the main source of supply of NGL and Natural Gas (NG) to the city of Lima, capital of Perú.
To repair the Third-Party damage, an emergency committee COLE by its acronym in Spanish (Local Emergency Operative Committee) was formed with the purpose to coordinate the actions for the execution of the repair and meet the Quality, Safety, Social and Environment standards. The committee had an important tool, the Operational Contingency Plan, which provided guidelines for dealing with an emergency. The job required isolating a section of 14-inch NGL transportation pipeline and a bypass to keep the pipeline operational. The work had a tight schedule that needed to be followed to reduce the environmental, safety and service risks. The situation presented several challenges including the use of double barriers to safeguard personnel and facility equipment during the pipeline repair. This double block methodology had to be applied to meet environmental and safety concerns. The damage was located at 4,495 meters above sea level (masl). The strike caused an NGL leak resulting in the installation of an NGL containment and storage system. This location lacked the logistical facilities for the attention of a pipe repair operation, adverse conditions of cold climate, desolate land and other conditions that had to be overcome. This paper discusses how social, safety, environment and logistical challenges were overcome to repair a damaged caused by third parties in an NGL pipeline, which resulted in timely repair completion and uninterrupted flow of NGL.
A Non-Intrusive Pipeline Leak Detection Service Using Pressure-Wave Analysis
Authors: Jagannathan Srinivasan , Stewart Neil , Jack Graham 
Published: November 2018

Product losses from pipelines, whether attributed to acts of man or nature, amount to operator losses of approximately USD 133 billion annually [1], not even considering costs associated with remediation, environmental damage, and reputational harm. When an incident occurs, pipeline operators need to minimize the event by quickly and accurately locating and quantifying the pipeline loss and its cause. Having this detailed knowledge enables determination of the best method for dealing with possible issues while helping minimize remediation costs, pipeline downtime, and the impact of the work on surrounding infrastructure.
Currently, most systems for pipeline leak detection are limited to either listening methods, which require being online and monitoring both pipeline ends at the moment the leak occurs, or intrusive methods that require the insertion of a pig into the pipeline. Both of these techniques are restricted in usage because access should be available to both ends of the pipeline. Additionally, for the intrusive method, the pipeline should be piggable and, for the listening method, the instrumentation should be able to communicate with a central data processing point placed at both pipeline ends as they rely on travel time difference between signals received at either end of the pipeline.
The method this paper describes is a proven, nonintrusive technology that can be used by pipeline operators to identify losses quickly and safely with a repeatable and verified high level of accuracy. It monitors the signature response of a generated fluid hammer and resulting pressure wave transiting within the pipeline and analyzes the reflected signature wave and pressure data to extrapolate both the location and magnitude of the loss with all pipeline parameters taken into account. The method enables operators to detect, locate, and quantify the loss of pipeline inventory in a safe and cost-effective manner without having to stop production, beyond the temporary closing of a mainline valve, or risk tools or personnel, due to exposure to pressurized fluids, before performing any intervention at the leak site.
