Abstract
Purpose
The purpose of this paper is to develop and implement a structural fatigue life estimation framework that includes laser‐peened (LP) residual stresses and then experimentally validates these fatigue life estimations.
Design/methodology/approach
A three‐dimensional finite element analysis of an Al 7075‐O three‐point bending coupon being LP was created and used to estimate the fatigue life when loaded. Fatigue tests were conducted to validate these estimations.
Findings
The framework developed for fatigue life estimation of LP‐processed coupons yielded estimates with goodness‐of‐fit between the log‐transformed experimental and analytical data of R2=0.97 for the baseline coupons and R2=0.94 for the LP‐processed coupons.
Research limitations/implications
Approximated ε‐life fatigue parameters were used to calculate the fatigue life resulting from the complex residual stress fields due to the simulated LP process.
Originality/value
A fatigue life estimation framework that considers LP residual stress fields has been developed for use on structural components.

Abstract
Purpose
Understanding customers is critical for service researchers and practitioners. Today, customers are increasingly active online, and valuable information about their opinions, experiences and behaviors can be retrieved from a variety of online platforms. Online customer information creates new opportunities to design personalized and high-quality service. This paper aims to review how netnography as a method can help service researchers and practitioners to better use such data.
Design/methodology/approach
A systematic review and analysis were conducted on 321 netnography studies published in marketing journals between 1997 and 2017.
Findings
The systematic review reveals that netnography has been applied in a variety of ways across different marketing fields and topics. Based on the analysis of existing netnography literature, empirical, theoretical and methodological recommendations for future netnographic service research are presented.
Research limitations/implications
This paper shows how netnography can offer service researchers unprecedented opportunities to access naturalistic online data about customers and, hence, why it is an important method for future service research.
Practical implications
Netnographic research can help service firms with, for example, service innovation, advertising and environmental scanning. This paper provides guidelines for service managers who want to use netnography as a market research tool.
Originality/value
Netnography has seen limited use in service research despite many promising applications in this field. This paper is the first to encourage and support service researchers in their use of the method and aims to stimulate interesting future netnographic service research.

Abstract
Purpose
This paper aims to examine two teachers’ beliefs and practices on teaching writing at an urban, high-performing middle school to determine: What discourses of writing are being taught in an urban, high-performing US public middle school? What factors prevent or enable particular discourses?
Design/methodology/approach
Drawing on case study methods, this study uses a single-case design with two seventh-grade teachers at a high-performing urban school as embedded units of analysis. Data collection took place over one semester. Data sources included observations and interviews with the two teachers, an interview with an administrator and multiple instructional artifacts, including unit and lesson plans. Observational data were analyzed using a priori code for writing discourses (Ivanic, 2004) and interview data were analyzed for factors affecting instruction using open, axial and selective coding.
Findings
Both teachers enacted extended multi-discourse writing instruction integrating skills, creativity, process, genre and social practices discourses supported by their beliefs and experience; colleagues; students’ relatively high test scores; and relative curricular freedom. However, there was minimal evidence of a sociopolitical discourse aligned with critical literacy practices. Limits to the sociopolitical discourse included a lack of a social justice orientation, an influx of low-performing students, a focus on raising test scores, data-focused professional development and district pacing guides. Racism is also considered as an underlying structural factor undermining the sociopolitical discourse.
Research limitations/implications
Although generalizability is limited because of the small sample size and the unique context of this study, two major implications are the need to layer discourses in writing instruction while centering critical pedagogy and develop teacher beliefs and knowledge. To support these two implications, this study suggests developing university-school partnerships and professional development opportunities that create a community of practice around comprehensive writing instruction. Future research will involve continuing to work with the participants in this study and documenting the effects of providing theory and tools for integrating the sociopolitical discourse into middle school curricula and instruction.
Originality/value
This study contributes to the field of literacy education’s understanding of internal and external factors limiting the sociopolitical discourse in a high-performing, urban middle school in the USA, an understudied context.

Abstract
Purpose
The purpose of this paper is to explore value formation in the customer-bank relationship outside the line of visibility of service encounters. The customer's own context has been overlooked by the bank marketing literature as it is traditionally focused on value created by the service process and outcome.
Design/methodology/approach
Positioned within the customer dominant logic, a netnography was conducted to explore how bank relationships are realised in customers’ own contexts and experiences. A total of 579 postings from discussions of retail banking in 18 online communities were collected and analysed.
Findings
The study uncovered four factors of invisible bank service value experienced by customers: shared moral value, responsibility value, relationship value, and heritage value.
Research limitations/implications
The study conceptualises bank service value as realised in the customers’ own contexts and thus highlights previously hidden sources of value in banking. The findings can be used for further conceptualisations of the customer dominant value formation of bank services.
Practical implications
The netnographic method illustrates how naturalistic data about customers’ retail bank experiences can be retrieved unobtrusively. The findings help bank management to understand what comprises customer value beyond the service encounter.
Originality/value
The paper contributes to the research in service marketing and bank marketing in three ways: first, a methodological contribution is the introduction of a netnographic approach to bank service value research. Second, a theoretical contribution is the uncovering of invisible value formation in the customer-bank relationship. Third, the paper uses the customer dominant logic in a banking context, thus providing insights into how banks are involved in the customer's own life.

Abstract
Purpose
The purpose of this paper is to report on a research project, using intervention research (IR), which aims to identify how a higher education institution could develop process improvement (PI) capability.
Design/methodology/approach
The paper adopts a practice perspectives of routines, and classifies and catalogues the potential routines that could form PI capability. The development of these routines are investigated using the constructive research approach, a form of IR), in the action research mode. Within this approach, the methodology of mediated discourse analysis was employed to trace the empirical trajectory of the routine development, in a student management office within the context of an improvement project by the institutions PI unit.
Findings
Of relative significance is the implication that there is a small group of initialising PI practices which are accessible to practitioners, in contrast to a large set of critical success factors. Second, these PI practices transcend particular methodologies, meaning their development can be incorporated into customised, contextualised methodologies, by individual organisations.
Practical implications
The set of PI practices identified are able to be enacted by practitioners and are not dependent on macro-management factors. Second they are relatively simple to understand and are not associated with any particular improvement fad or fashion.
Originality/value
The study contributes to the appreciation of PI in higher education as a capability, and outlines the potential array of routines that could constitute that capability. It provides a theoretical view on how key PI routines are developed in an organisational field, and a more nuanced and richer view of “process mapping” and its effect on other PI practices.

Abstract
Purpose
The purpose of this paper is to understand how Design for Additive manufacturing Knowledge has been developing and its significance to both academia and industry.
Design/methodology/approach
In this paper, the authors use a bibliometric approach to analyse publications from January 2010 to December 2020 to explore the subject areas, publication outlets, most active authors, geographical distribution of scholarly outputs, collaboration and co-citations at both institutional and geographical levels and outcomes from keywords analysis.
Findings
The findings reveal that most knowledge has been developed in DfAM methods, rules and guidelines. This may suggest that designers are trying to learn new ways of harnessing the freedom offered by AM. Furthermore, more knowledge is needed to understand how to tackle the inherent limitations of AM processes. Moreover, DfAM knowledge has thus far been developed mostly by authors in a small number of institutional and geographical clusters, potentially limiting diverse perspectives and synergies from international collaboration which are essential for global knowledge development, for improvement of the quality of DfAM research and for its wider dissemination.
Originality/value
A concise structure of DfAM knowledge areas upon which the bibliometric analysis was conducted has been developed. Furthermore, areas where research is concentrated and those that require further knowledge development are revealed.
