This paper aims to develop a method to extract the weld seam from the welding image.
Abstract
Purpose
This paper aims to develop a method to extract the weld seam from the welding image.
Design/methodology/approach
The initial step is to set the window for the region of the weld seam. Filter and edge‐operator are then applied to acquire edges of images. Based on the prior knowledge about characteristics of the weld seam, a series of routines is proposed to recognize the seam edges and calculate the seam representation.
Findings
The proposed method can be used to extract seams of different deviations from noise‐polluted images efficiently. Besides, the method is low time‐consuming and quick enough for real time processing.
Practical implications
Weld seam extraction is the key problem in passive vision based seam tracking technology. The proposed method can extract the weld seam even when the image is noisy, and it is quick enough to be applied in seam tracking technology. The method is expected to improve seam tracking results.
Originality/value
A useful method is developed for weld seam extraction from the noise‐polluted image based on prior knowledge of weld seam. The method is robust and quick enough for real time processing.

Abstract
Purpose
This paper aims to serve as an introduction to and overview of this special issue of the Journal of Educational Administration entitled “Building organisational capacity in school education”. The co‐editors have solicited contributions from authors in Wales, Australia, Canada, the USA, England, Hong Kong and New Zealand.
Design/methodology/approach
The paper reviews past and contemporary approaches to the issue of capacity building in education and in particular, sustainable capacity building. As well as reviewing key researchers and writers in this field, including their own work, the authors foreshadow and synthesise the other seven papers that make up this special issue.
Findings
The paper contends that building capacity in schools and schooling, while no means easy, can be both understood and accomplished. However, caution needs to be exercised because hard‐fought gains in capacity building and sustainability can be quickly eroded under the influence of poor leadership or extraneous changes.
Practical implications
The paper serves as a framework both for the seven papers that follow and more generally for understanding and conceptualising sustainable school capacity building.
Originality/value
The paper performs the function of framing current debates and pressures around sustainable school capacity‐building in an international theoretical and practical context.

Abstract
Purpose
Given that a relatively large percentage of college students entering historically black colleges and universities (HBCUs) are first-generation students and considering the low completion rate among this group in the science, technology, engineering and mathematics (STEM) discipline, the purpose of this preliminary meta-synthesis study is intended to facilitate a greater understanding of the academic and social adjustment among college students, particularly first-generation college students enrolled in STEM disciplines at HBCUs. Therefore, this meta-synthesis will shed light and offer important recommendations for university administrators and faculty members in supporting the academic and social adjustment of these students in STEM fields at HBCUs.
Design/methodology/approach
This review of literature was conducted using a meta-synthesis approach (also referred to as integrative review). A meta-synthesis is based on a process by which findings across multiple studies are organized and presented (Turner, Gonzalez and Wood, 2008; Wood, 2010). This approach is used to provide insight to academicians and practitioners alike on the status of research on a given phenomenon (Bland, Meurer and Maldonado, 1995; Patterson, Thorne, Canam and Jillings, 2001; Wood, 2010). We engaged in a cyclical process of collecting, annotating, and synthesizing research over a 45-year time-frame (1970 to 2015). This produced over 50 cited resources with more than 100 scholars including peer-reviewed articles, reports, books, book chapters, and conference papers.
Findings
Factors present in the literature that affected students enrolled in a STEM program at a HBCU are grouped into three contexts: (a) first-generation academic and social characteristics, (b) first-generation college dropout and transition, and (c) first-generation STEM retention. Tables 2 to 4 provide these contexts by author and year of publication. Within these general groupings, four interrelated themes emerged from the literature: (a) prior academic performance and STEM discipline, (b) college adjustment and STEM discipline, (c) social integration and STEM discipline, and (d) academic integration and STEM discipline.
Originality/value
This information may help professors and university professionals in the STEM fields to be more aware of the challenges faced by incoming college students. More empirical work is needed in this area in a way that is useful for understanding and enhancing professors’ and university professionals’ knowledge. To this end, research that carefully describes what HBCU professors and university professionals know or their ideas about teaching college students, especially first-generation students enrolled in the STEM discipline, is needed.

Abstract
Purpose
Social media use is prevalent today, but there is a possibility that it might go out of control and cause negative consequences. Furthermore, by using social media at work, businesses may develop their networks, communicate in a productive manner and ultimately expand the efficiency. The purpose of this study is to investigate the effect of social media use (SMU) on job performance (JP) through sequential mediators such as social capital dimensions (SC), self-efficacy (SE), job satisfaction (JS) and knowledge sharing (KS) in Indian Public Universities.
Design/methodology/approach
Serial mediation model has been used in the study to analyse the relationship. Data is collected from teaching faculty (n = 702) who use social media in Indian public universities. The study has assessed the association between variables using structural equation modelling.
Findings
The findings suggest that the dimensions of SC, SE, JS and KS sequentially mediated the effect of SMU on JP. In light of the results, the SMU specifies prerequisites for the development of various dimensions of SC. Similarly, the rest of the mediating constructs further affect the other constructs, which ultimately positively affect JP. The final result shows that the indirect effect between social media use and job performance is positive and significant.
Practical implications
The study provides practical suggestions for university administration regarding the use of social media for teaching faculty.
Originality/value
No research has been done regarding social media use affecting the job performance of teaching faculty through serial mediation in public universities. In this respect, this study represents an original attempt to conduct such research.

Abstract
Purpose
The purpose of this paper is to outline how collective capacity building is supporting system‐wide reform in one country. It seeks to outline the way in which professional learning communities within, between and across schools are creating an infrastructure for improving professional practice and raising standards.
Design/methodology/approach
The paper is both descriptive and analytical. It draws on the international literature pertaining to system‐wide reform and the empirical evidence concerning professional learning.
Findings
The paper highlights some of the challenges in building the collective capacity for change throughout an entire system and reflects on progress to date. The paper concludes by arguing that despite the compelling case for collective capacity building, the real test is to make it happen.
Research limitations/implications
The professional learning communities (PLC) programme in Wales is gathering evidence about impact but as the programme is just completing its first year of implementation these findings are not yet available.
Originality/value
This paper adds to prior analyses and discussion of collective capacity building by providing a system‐wide perspective.

Abstract
Purpose
The goal of this narrative synthesis is twofold. The purpose of this paper is to understand the barriers and constraints that hinder or prevent the growth of professional community. The author also want to form an empirical understanding of how educators can be successful in meeting these challenges. In both cases, the author wish to grow this knowledge in the complexity of schooling and the rapids of continuous school improvement. The conceptual architecture for the review is a mixture of research on change and implementation, school improvement, and community.
Design/methodology/approach
The paper can best be described as an integrative review or a narrative synthesis – an interpretation of the literature (Vescio et al., 2008), a method that is especially useful when combing qualitative and quantitative research findings. The author follow guidance from Hallinger in explaining the construction of the paper. The goal is to explore the broadest landscape possible to distill knowledge and understanding on the one hand and provide usable material on the other. In the words of Battistich, the aim is “to develop integrative explanatory concepts that provide people with a useful framework for considering action under particular circumstances.”
Findings
The paper concludes that there are dynamic cultural and well-entrenched structural barriers that make the realization of professional community problematic. Some of these elements are visible. Many others are deeply buried in the meta-narrative of school improvement. The author also finds that absent direct attention to these conditions, efforts to nurture professional community in schools will be seriously handicapped.
Research limitations/implications
Narrative syntheses offer the hope of deep understanding of domains of school improvement. They permit the inclusion of findings garnered from an array of methodologies. At the same time, this mode of investigation lacks the precision associated with more structured methods of knowledge accumulation. Even when done well, it places considerable responsibility on investigators in making sense of findings.
Originality/value
By examining research from a wide area of domains, the author is able to construct a comprehensive map of the world of bringing professional community to life in schools for researches, policy actors, developers, and practitioners.

Abstract
Few studies have addressed the experiences of a graduate’s transition from university to the world of work. Understanding how graduates react and respond to this journey will provide universities with the ability to prepare and equip students for the road ahead. The purpose of this particular Australian case study was to extend understanding of the experience of making the transition from university to work, and to identify questions for further study. Data were collected using semi‐structured interviews, which were transcribed and analysed for clusters of common themes. Four themes emerged from the case study: “an uncertain feeling”, “inflated expectations”, “the work experience paradox” and “a low time”. It is hoped that understanding this graduate’s experiences will assist higher education institutions, recruiting companies and students to better understand and prepare for this significant life passage.
