This paper aims to present a method for predicting dimensional variation in assembly processes of a wingbox structure concentrating on the assembly of skin panels to rib feet.
Abstract
Purpose
This paper aims to present a method for predicting dimensional variation in assembly processes of a wingbox structure concentrating on the assembly of skin panels to rib feet.
Design/methodology/approach
Finite element modelling and experimental tests are conducted on the rib structure based on the site measurement gathered from the Airbus assembly factory.
Findings
The results have shown that the simulated model has the capability of predicting to an acceptable degree of accuracy the overall geometrical variations of the ribs and skin panels, as well as the positional variations of each individual rib foot.
Originality/value
The authors believe that no previous research has offered a similar prediction method for large aerostructures.

Abstract
Purpose
This paper aims to use the Monodepth method to improve the prediction speed of identifying the obstacles and proposes a Probability Dueling DQN algorithm to optimize the path of the agent, which can reach the destination more quickly than the Dueling DQN algorithm. Then the path planning algorithm based on Probability Dueling DQN is combined with FastSLAM to accomplish the autonomous navigation and map the environment.
Design/methodology/approach
This paper proposes an active simultaneous localization and mapping (SLAM) framework for autonomous navigation under an indoor environment with static and dynamic obstacles. It integrates a path planning algorithm with visual SLAM to decrease navigation uncertainty and build an environment map.
Findings
The result shows that the proposed method offers good performance over existing Dueling DQN for navigation uncertainty under the indoor environment with different numbers and shapes of the static and dynamic obstacles in the real world field.
Originality/value
This paper proposes a novel active SLAM framework composed of Probability Dueling DQN that is the improved path planning algorithm based on Dueling DQN and FastSLAM. This framework is used with the Monodepth depth image prediction method with faster prediction speed to realize autonomous navigation in the indoor environment with different numbers and shapes of the static and dynamic obstacles.

Abstract
Purpose
The purpose of this literature review is to describe how eating disorders among adolescents affect family relationships and the family’s daily living conditions and to describe the family’s experienced need for professional support.
Design/methodology/approach
An integrative literature review based on the method of Whittemore and Knafl. In all, 15 articles with both qualitative and quantitative approaches were reviewed.
Findings
The results are presented in two main themes: a disharmonic family and the need for input from healthcare professionals. The results are discussed using Callista Roy’s adaptation model and the adaptive modes: group identity mode, role function and interdependence.
Originality/value
This review paper will be of interest to clinical nurses and other professionals who encounter families to clarify how the relationships and roles change within the family. To the authors knowledge, no integrative review has paid attention to how the relational aspects of the family members, their social roles and role constructions within the family affect daily living.

Abstract
Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract
Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract
Purpose
The purpose of this paper is to explore the state of extinction accounting, and the motivations for its use in the UK public sector. Prior studies are mostly concerned with corporate attempts to account for species, despite studies in related areas calling for examinations of the public sector context.
Design/methodology/approach
The paper analyses the use of extinction accounting in three separate case organisations, conducting a total of 21 interviews across the three cases. Interviews were conducted with a range of organisational participants each having experience with extinction accounting.
Findings
Interviews reveal a number of common uses and applications of extinction accounting across the three councils. Practices are used to generate reports on species loss and recovery within each region, and to facilitate planning for species protection and recovery. However, in attempting to use this information, key trade-offs emerge between satisfying economic and ecological criteria, and even trade-offs are created regarding development of protection schemes. This leads to a subversion of extinction accounting.
Research limitations/implications
Commensurate with prior studies in the corporate context, the study finds the presence of an economic logic impinging upon ecological decision making, suggesting that practices of extinction accounting may be affected by the same acknowledged economic motivations that reside in corporate attempts to account for nature.
Originality/value
The paper makes an important contribution by evaluating the public sector context of extinction accounting, which is lacking in existing research. The findings relating to the public sector use of species and extinction information also provide a useful context to understand how relatively new social and environmental accounting practices are deployed in organisations, as well as some indication of their effectiveness and limitations.

Abstract
Purpose
Though brand love is recognized as being an important marketing topic both for theory and practice, a gap still exists with regard to its operationalization. To bridge this gap, this paper proposes a single-item measure (SIM) that uses a visual rating scale (i.e., a rating scale combining verbal with nonverbal contents).
Design/methodology/approach
Three studies covering over 700 respondents and examining three international brands over three product categories were conducted to test the new measure.
Findings
Findings provide consistent evidence for the reliability and validity of the proposed measure. They also demonstrate that brand love, as gauged by the new SIM, is good in predicting positive word of mouth, willingness to pay a higher price, and willingness to forgive brand mishaps.
Research limitations/implications
The paper focuses on brand love mainly from a measurement perspective.
Practical implications
This paper provides a practical and parsimonious tool to measure brand love.
Originality/value
Extant SIMs of brand love are less than ordinal, content invalid, of unknown reliability, and of untested concurrent validity. This paper provides academics and practitioners alike with a SIM of brand love that is ordinal, content valid, and tested in terms of reliability and concurrent validity.

Abstract
Purpose
This study aims to focus on the application of a multiple criteria decision analysis (MCDA) method to compare results presented by the Integrated Goals System based on the 12th edition of the Integrated Public Safety Areas (IPSAs) Award, which achieved goals established for Strategic Crime Indicators for the state of Rio de Janeiro, Brazil. The main objective of this research was to limit the compensatory effects of classification criteria on IPSAs that have achieved goals established for crime indicators by applying the MCDA method.
Design/methodology/approach
The methodology was based on the application of MCDA. The MCDA method selected and used was ELECTRE III, being implemented by J-Electre software.
Findings
Compared to results of the current method, the results of the ELECTRE III method showed a 94.87 per cent change in ranking positions revealed via the SIM method. This finding denotes the elimination of compensatory effects of the criteria. As a consequence, it can be affirmed that the application of resources by IPSA managers to reduce the prevalence of a single strategic crime indicator is no longer a success factor for awarding in the established goal system.
Research limitations/implications
As limitations, it is possible to indicate the time cut used to carry out the research. The research may be extended to other issues of the productivity award.
Practical implications
The methodology applied with the use of ELECTRE III revealed that the government could reduce the cost with the incentive program to reduce criminal indices.
Social implications
As the MCDA method is based on a binary pairwise comparison system, the methodology imposes a change of attitude on local managers fighting crime to reduce crime indicators and to consequently build a local sense of safety in IPSAs.
Originality/value
This research fills a gap in the literature because there are few studies using the MCDA method in the field of public security. The value of the work lies in the creation of a method that gives the decision-maker, of the law enforcement agency, an alternative to improve the process of rewarding by productividad of the integrated areas of public security.
