DNA Topology in Chromatin is Defined by Nucleosome Spacing
Authors: Nikitina Tatiana , Norouzi Davood , Grigoryev Sergei A. , Zhurkin Victor B. 
Published: January 2017

ABSTRACTIn eukaryotic chromatin, DNA makes about 1.7 left superhelical turns around an octamer of core histones implying that formation of nucleosomes would alter the overall topology of DNA by a comparable difference of the DNA linking number (ΔLk) per nucleosome. However, earlier experiments have documented a significantly (about 50%) lower absolute value |ΔLk| than expected from the nucleosome geometry. Recently, using computer modeling, we have predicted two families of energetically stable conformations of the arrays with precisely positioned nucleosomes, one with an integer number of DNA turns in the linker DNA {L = 10n} and the other with extra five base pairs in the linker {L = 10n+ 5}, to be topologically different. Here, using arrays of precisely positioned clone 601 nucleosomes, topological electrophoretic assays, and electron microscopy we experimentally tested these predictions. First, for small 12-mer nucleosome circular arrays we observed that dLk per nucleosome changes from −1.4 to −0.9 for the linkers {L = 10n} and {L = 10n+ 5}, respectively. Second, for larger hybrid arrays containing a mixture of positioned and non-positioned nucleosomes we found that changing the DNA linker length within the positioned arrays was sufficient to significantly alter the overall DNA topology fully consistent with our prediction. The observed topological polymorphism of the circular nucleosome arrays provides a simple explanation for the DNA topology in native chromatin with variable DNA linker length. Furthermore, our results may reflect a more general tendency of chromosomal domains containing active or repressed genes to acquire different nucleosome spacing to retain topologically distinct higher-order structures.
Control system designing for correcting wing–fuselage assembly deformation of a large aircraft
Authors: Fang Qiang , Chen Weidong , Zhao Anan , Deng Changxi , Fei Shaohua 
Published: January 2017

Purpose
In aircraft wing–fuselage assembly, the distributed multi-point support layout of positioners causes fuselage to deform under gravity load, leading to assembly difficulty and assembly stress. This paper aims to propose a hybrid force position control method to balance aerodynamic shape accuracy and deformation of assembly area, thereby correcting assembly deformation and reducing assembly stress.

Design/methodology/approach
Force and position control axes of positioners are selected based on screw theory and ellipsoid method. The position-control axes follow the posture trajectory to align the fuselage posture. To exert force on the fuselage and correct the deformations, the force-control axes follow the contact force derived by using orthogonal experiments and partial least squares regression (PLSR). Finite element simulation and one-dimension deformation correction experiment are conducted to verify the validity of this method.

Findings
Simulation results indicate that hybrid force position control method can correct assembly deformation and improve the wing–fuselage assembly quality significantly. Experiment on specimen verifies the effect of this method indirectly.

Originality/value
The proposed method gives a solution to solve the deformation problem during aircraft wing-fuselage assembly, thereby reducing assembly stress and improving assembly quality.
Scheduling the in-house logistics distribution for automotive assembly lines with just-in-time principles
Authors: Zhou Binghai , Peng Tao 
Published: January 2017

Purpose
This paper aims to investigate the just-in-time (JIT) in-house logistics problem for automotive assembly lines. A point-to-point (P2P) JIT distribution model has been formulated to specify the destination station and parts quantity of each delivery for minimizing line-side inventory levels.

Design/methodology/approach
An exact backtracking procedure integrating with dominance properties is presented to cope with small-scale instances. As for real-world instances, this study develops a modified discrete artificial bee colony (MDABC) metaheuristic. The neighbor search of MDABC is redefined by a novel differential evolution loop and a breadth-first search.

Findings
The backtracking method has efficaciously cut unpromising branches and solved small-scale instances to optimality. Meanwhile, the modifications have enhanced exploitation abilities of the original metaheuristic, and good approximate solutions are obtained for real-world instances. Furthermore, inventory peaks are avoided according to the simulation results which validates the effectiveness of this mathematical model to facilitate an efficient JIT parts supply.

Research limitations/implications
This study is applicable only if the breakdown of transport devices is not considered. The current work has effectively facilitated the P2P JIT logistics scheduling in automotive assembly lines, and it could be modified to tackle similar distribution problems featuring time-varying demands.

Originality/value
Both limited vehicle capacities and no stock-outs constraints are considered, and the combined routing and loading problem is solved satisfactorily for an efficient JIT supply of material in automotive assembly lines.
A new method for automatic shaft-hole assembly of aircraft components
Authors: Jiang Junxia , Bian Chen , Ke Yinglin 
Published: January 2017

Purpose
The purpose of this paper is to design a new method to realize automatic assembly of aircraft components with large shafts such as canard and vertical tail. The assembly structure of component with large shaft and fuselage is a mating assembly structure, and it is a challenge to satisfy the precision and assembly requirement.

Design/methodology/approach
According to the assembly structure features and process requirements of an aircraft component with large shaft, the operating principle of precise assembly system for shaft-hole mating is analyzed in this paper. The model of compliant assembly for shaft-hole mating is constructed, and force condition analysis of the compliant assembly is performed. An automatic precise shaft-hole assembly method for aircraft assembly using 5 degrees of freedom spatial mechanism, compliance technology and servo feeding system is put forward based on the analysis. A 5 degrees of freedom passive compliant experimental equipment has been developed.

Findings
Application test results of the 5 degrees of freedom passive compliant experimental equipment show that the simulated canard can be mated automatically and accurately through this method with high efficiency and high quality as long as the tip of shaft enters into the range of hole’s chamfer.

Practical implications
This method has been used in an aircraft assembly project. The practical results show that the aircraft components with large shafts can be mated automatically and accurately through this method with high efficiency and high quality.

Originality/value
This paper presents a new method and designs a new assembly system to realize the assembly of the aircraft components with large shafts. The research will promote the automation of fuselage assembly.
The ad format-strategy effect on comparative advertising effectiveness
Authors: Kalro Arti D. , Sivakumaran Bharadhwaj , Marathe Rahul R. 
Published: January 2017

Purpose
Extant research on comparative advertising has focused only on “market leader” comparisons (a brand targeting the market leader), whereas in the marketplace, “multi-brand” comparisons are more prevalent (Kalro et al., 2010). Moreover, most research focuses on direct comparisons only. Hence, this research aims to investigate the interplay between comparison ad strategy (“market leader”/“multi-brand” comparisons) and comparison ad format (direct/indirect comparisons) on the effectiveness of comparative advertising.

Design/methodology/approach
This paper uses four 2 × 2 fully crossed factorial designs (comparison ad format: direct vs indirect and comparison ad strategy: market leader vs multi brand) with established and new brands in two categories: powdered detergents and smart phones. All studies were conducted in metropolitan cities of India.

Findings
By and large, the experiments indicated that direct (indirect) comparisons lowered (heightened) perceived manipulative intent and enhanced (reduced) attitude-toward-the-ad for multi-brand (market leader) comparisons.

Practical implications
Findings suggest that when advertisers use comparative advertising, they may use direct ads when using multi-brand comparisons and use indirect ones when using market leader comparisons. It could also be argued that when advertisers use multi-brand comparisons because of fragmentation in the marketplace, they may directly compare against these multiple brands. When advertisers need to compare against a market leader, they may do so indirectly.

Originality/value
This research is among the first to investigate multi-brand comparisons that are widely used in the industry and that too in the context of both direct and indirect comparison formats.
The relative influence of advertising and word-of-mouth on viewing new season television programmes
Authors: Romaniuk Jenni , Hartnett Nicole 
Published: January 2017

Purpose
This paper aims to investigate the relative influence of advertising and word of mouth (WOM) for new season TV programmes, both new and returning.

Design/methodology/approach
The study’s longitudinal research design tracks individuals before and after possible exposure to advertising and/or positive WOM (PWOM) to model the effects of both paid versus earned media on behaviour.

Findings
This study provides contrary evidence to previous research that suggests that WOM has more influence on consumers than advertising. By controlling for viewers’ benchmark probabilities of viewing the TV programme, the effect of receiving PWOM becomes insignificant, whereas the effect of TV advertising remains unchanged. Because WOM is commonly exchanged between people with shared interests, it reaches an audience that is already highly disposed to view the TV programme.

Research limitations/implications
The findings implicate that we need to reinvestigate the power of WOM to avoid misattribution of effects. This study is only study in one category, which means replication and extension to more categories are needed. The limitations of the study include the inability to control for creative differences in the execution of programme promotions or examine possible cross-media synergies for multimedia campaigns.

Practical implications
Findings have implications for how much to invest in WOM-generating activities. Findings also have wider implications for cross-media research and media-mix models, as different media may reach audiences with differing predispositions to act.

Originality/value
This is one of the rare individual-level, longitudinal studies that investigate the influence of WOM in comparison to advertising.
Gratitude mediates consumer responses to marketing communications
Authors: Bridger Emma K. , Wood Alex 
Published: January 2017

Purpose
From Adam Smith onwards, gratitude has been held as invaluable to societal functioning in view of its role in helping individuals maintain their reciprocal obligations to one another. The purpose of the current research is to use current conceptions of gratitude derived from work in social psychology to test whether simple descriptions of hypothetical organisations could systematically differ in the extent to which they elicit gratitude, and subsequently, whether gratitude would mediate behavioural intentions towards these organisations.

Design/methodology/approach
In two studies, participants read vignettes describing hypothetical organisations that systematically differed in the extent to which the services they provided were costly to the organisation, of high value and provided out of a genuine desire to help. Perceptions of these dimensions, feelings of gratitude and behavioural intentions towards each organisation were subsequently measured.

Findings
The appraisal group manipulation significantly affected consumers’ behavioural intentions towards these businesses, and the majority of these relationships were mediated by feelings of gratitude towards the organisations.

Research limitations/implications
These data indicate that gratitude not only mediates customer responses to relationship marketing investments, but may also be integral in marketing communications’ role in converting non-customers to customers. They also indicate that marketing communications should stress that an organisations services are of high value, of cost to the organisation and provided out of a genuine desire to help.

Originality/value
This paper shows for the first time that the same cognitive appraisals that underpin feelings of interpersonal gratitude mediate responses to global evaluations of organisations. This considerably broadens the situations under which gratitude had previously been considered to operate and argues for the inclusion of gratitude in understanding how marketing communications and relationship management are used to influence consumer responses.
An empirical study on the impact of online word-of-mouth sources on retail sales
Authors: Hong Hong , Xu Di , Xu Dapeng , Wang G. Alan , Fan Weiguo 
Published: January 2017

Purpose
This study aims to analyze the impact of the source of online word-of-mouth (WOM) on retail sales. Specifically, the authors focus on the relative impact of external and internal WOMs on book sales.

Design/methodology/approach
An empirical analysis is conducted with a panel data of sales and WOM for 87 books from Dangdang and Douban over a 14-day period based on two generalized least square regression models.

Findings
Results suggest that both internal WOM and external WOM have significant impact on product sales, and the impact of external WOM is relatively more significant.

Social implications
WOM, especially the external WOM, plays an important role in consumers’ online purchase decisions.

Originality/value
This study is helpful for retailers to better understand the factors influencing the sales and thereby forecast the future sales more precisely. Besides, the research conclusion could also enlighten related decision makers to constantly improve technical platforms.
Differentiating between pathological demand avoidance and antisocial personality disorder: a case study
Authors: Trundle Grace , Craig Leam A. , Stringer Ian 
Published: January 2017

Purpose
The purpose of this paper is to explore the different clinical features of pathological demand avoidance (PDA) and antisocial personality disorder (ASPD) presented in the form of a single case study. The study highlights the potential of misdiagnosis and conceptual confusions to practitioners in forensic settings between the two conditions when working with offenders with personality disorders.

Design/methodology/approach
A case formulation using the “five Ps” method based on the personal history of an incarcerated male is presented and the clinical similarities and differences between PDA and ASPD are delineated. These differences and similarities are evaluated and applied to offender management including intervention options.

Findings
There are considerable similarities between ASPD and PDA making the two conditions difficult to separate. Both diagnostic criteria identify childhood behavioural problems, aggression, destructiveness, conduct disorder (CD), manipulation and non-compliance as indications of the disorder. For example, the criteria for later adult ASPD are the presence of childhood antisocial behaviour and CD. However, these behaviours may also be suggestive of the attention deficit hyperactivity disorder and non-compliance that are part of PDA. Violent behaviours and aggression can also be perceived in a similar way. Misdiagnosis of PDA as ASPD reduces the efficiency of treatment programmes.

Originality/value
The implications of these findings could prove useful in the successful risk management of offenders with PDA. Given the similar behavioural characteristics between PDA and ASPD, the prevalence of PDA among offenders may be higher than observed. The aim of this study is to raise awareness of potential conceptual complications and clinical confusions between the two conditions with a view to aid offender management through case formulation. A large scale study into offenders with PDA would draw attention to the prevalence of the condition as well as its association with offending behaviour.
Why are customers loyal in sharing-economy services? A relational benefits perspective
Authors: Yang Shuai , Song Yiping , Chen Sixing , Xia Xin 
Published: January 2017

Purpose
This study aims to provide a taxonomy of relational benefits that drive customer loyalty in sharing-economy services, assess the relative strengths of these relational benefits in influencing customer loyalty and examine whether commitment mediates the influence of relational benefits on customer loyalty in this context.

Design/methodology/approach
Relational benefits of sharing-economy services were explored through a focus group interview, followed by an online survey completed by 440 respondents in China. Structural equation modeling was used to test the hypotheses.

Findings
This study shows that confidence and social benefits have significant and positive effects on commitment in sharing-economy services. In addition, safety benefits, a new type of relational benefits, also significantly affect commitment in this context. Furthermore, the findings suggest that commitment acts as a mediator between confidence, social and safety benefits and customer loyalty. Special treatment benefits had no effect on commitment and loyalty in the sharing-economy context.

Practical implications
This paper provides sharing-economy service providers with insight on how to better create and sustain loyal relationships with customers through the provision of relational benefits.

Originality/value
This study offers initial insight into why customers would stay in peer-to-peer relationships in the sharing economy, and suggests how to strengthen relationships between customers and peer service providers.
“Running is my boyfriend”: consumers’ relationships with activities
Authors: Mickelsson Karl-Jacob 
Published: January 2017

PurposeThe paper aims to introduce the idea that consumers have relationships with their own recurring activities. Instead of the usual notion of investigating the relationships between actors, or between actors and their possessions, the paper focuses on the relationship between an actor and a particular activity in which the actor regularly participates.Design/methodology/approachThe paper is conceptual and exploratory in nature. It discusses different perspectives of consumer activity in marketing and then introduces a relationship view of activity. The paper proceeds to outline the conceptual foundations of this view by applying relationship characteristics found in the literature. Quotes from runners’ blogs are used to illustrate the different identified relationship themes.FindingsThe paper argues that consumers can be seen as having long-term relationships with their activities, and it introduces the concept of the “activity relationship”. The paper proceeds to demonstrate how this concept differs from the previous conceptualization of consumer activity and relationships.Research limitations/implicationsThe activity-relationship perspective on consumer behavior opens up new venues for marketing research. It also facilitates new types of marketing practice, whereby producers can focus on supporting their customers’ relationships with valuable activities.Originality/valueThe paper presents a novel perspective on relationships. It contributes to consumer research and the customer-dominant view of marketing, whereby the customer’s perspective is put in focus and businesses serve as ingredients in the customer’s own context.
Converting financial statements: operating to capitalised leases
Authors: Xu Wei , Davidson Robyn Alexandra , Cheong Chee Seng 
Published: January 2017

Purpose
The purpose of this paper is to examine how capitalising operating leases under IFRS 16/AASB 16 affects the financial statements and value relevance of financial information. In doing so, limitations of exiting methods are highlighted and improved upon.

Design/methodology/approach
Imhoff et al.’s (1991) constructive method for capitalising operating leases is improved upon and used to restate the financial statements of 165 S&P/ASX200 companies. The financial position, key ratios and value relevance are tested for significant differences.

Findings
The results provide evidence that capitalising operating leases affects financial statements and value relevance.

Originality/value
Imhoff et al.’s (1991) constructive method has been refined, providing an improved method for capitalising operating leases than the one that has been used in the past. From a practical perspective, this research provides evidence supporting the “right-of-use” method proposed by the IASB which will see previous off-balance-sheet leases recognised.
Public goods, sustainable development and business accountability
Authors: Bardy Roland 
Published: January 2017

Purpose
The purpose of this paper is to present a linkage between performance measurement at the business level and the concept of public goods usage, and a linkage between the micro- and macro-economic aspects of sustainability.

Design/methodology/approach
Exhibiting the essentials of a public goods cost perspective in order to initiate discussion between statisticians, standard setters for business reporting and practitioners.

Findings
Showing what has been achieved in measuring the outcomes of sustainable development efforts and what still needs to be done in order to arrive at aggregate values for national and global commons.

Research limitations/implications
Linking performance measurement at the business level to public goods usage will depend on the co-operation of businesses and national statistics which test the feasibility of monetary indicators for both the micro- and the macro-levels.

Practical implications
For practitioners in both the statistics profession and management accounting who are concerned with measurement of socioeconomic and environmental phenomena, this attempt at integrating sustainable development indicators and the managerial control system of companies might provide a valuable proposition. It is also a useful contribution to the ongoing debate of the value and credibility of sustainability reporting.

Social implications
If businesses make no attempts to exhibit numerically how they contribute to preserving and expanding the societal commons, they will be confronted with ever-growing agitation from pressure groups and they might be bypassed in the discussion on the issue of sustainability parameters that those groups are advocating.

Originality/value
This is the first academic paper that demonstrates a reporting model which unites business accounts and national accounts.
