Citizen Science – public participation in scientific projects – is becoming a global practice engaging volunteer participants, often non-scientists, with scientific research. Citizen Science is facing major challenges, such as quality and consistency, to reap open the full potential of its outputs and outcomes, including data, software and results. In this context, the principles put forth by Data Science and Open Science domains are essential for alleviating these challenges, which have been addressed at length in these domains. The purpose of this study is to explore the extent to which Citizen Science initiatives capitalise on Data Science and Open Science principles.

The authors analysed 48 Citizen Science projects related to pollution and its effects. They compared each project against a set of Data Science and Open Science indicators, exploring how each project defines, collects, analyses and exploits data to present results and contribute to knowledge.

The results indicate several shortcomings with respect to commonly accepted Data Science principles, including lack of a clear definition of research problems and limited description of data management and analysis processes, and Open Science principles, including lack of the necessary contextual information for reusing project outcomes.

In the light of this analysis, the authors provide a set of guidelines and recommendations for better adoption of Data Science and Open Science principles in Citizen Science projects, and introduce a software tool to support this adoption, with a focus on preparation of data management plans in Citizen Science projects.

The area of behavioural phenotype research and related clinical practice is now recognised as one of high relevance to all practitioners who help people with learning disabilities, whatever their age. Knowledge continues to accumulate rapidly regarding aspects pertaining to aetiology, likely developmental, emotional and behavioural challenges, useful multidisciplinary interventions and supports and long‐term prognosis. This paper reviews the concept, its history and recent developments, focusing on those aspects which are of particular importance to clinical and other care and support professionals and their clients. There is a continuing need for widespread dissemination of the large body of relevant information, and its application to practice in order to maximise benefits for people with learning disabilities and their families.

Sleep disorders are extremely common in children and young people, and even more so in those with developmental disabilities. This client subgroup may prove refractory to standard behavioural and other psychosocial interventions that usually help and it is frequent for clinicians to resort to medication approaches given the high levels of personal and family distress that result. There is a need not only for further well structured research in this field but also for efforts to tackle the frequent relative neglect by clinicians of more researched and considered approaches. This review examines these issues selectively, focusing on important clinical issues and predicaments, and attempts a start at an evidence‐based background for practical and rational prescribing in this area of common childhood psychopathology.

This report explores the relationship between the autosomal recessive disorder Schwachman‐Diamond syndrome (SDS) and neurodevelopmental disorders such as attention deficit hyperactivity disorder (ADHD), autistic spectrum disorder (ASD), mixed receptive‐expressive language disorder and intellectual disability. It also reflects on the management of associated developmental, emotional and behavioural challenges. A six‐year‐old boy with SDS underwent comprehensive psychiatric and psychological assessment and was found to meet DSM‐IV‐TR (APA, 2000) diagnostic criteria for ADHD combined type and to have mild intellectual disability. A diagnosis of ASD was excluded. Management of his ADHD included psycho‐education, behaviour modification, educational recommendations and medication. This study adds to knowledge of Shwachman‐Diamond syndrome and management of co‐morbid neurodevelopmental disorders.

The purpose of this paper is to identify the major factors of client satisfaction (CS) that are critical for web development projects in freelance marketplaces. This quantitative study is done from the point of view of the web development services clients. Five major dimensions were proposed as determinants of CS from the literature review: ease of use, user interface, information, security and privacy.

A web-based survey methodology is used as the main data collection instrument. Statistical techniques such as confirmatory factor analysis and multiple linear regressions are used to analyze 162 responses of questionnaires.

The findings suggest that all factors do influence CS. In terms of strength, security had the highest level of impact on CS, so it is the strongest determinant among all factors. After security, ease of use and information are considered as strong determinants. So, this study concludes that the five major determinates do affect CS in web development projects from freelance marketplaces.

This research is limited only to the top freelance marketplaces, such as Upwork, Freelancer, Fiverr, Guru, Envato Studio, etc. The sample size is relatively small and this study is focused on web development projects only. Moreover, this research is focused only on the characteristics or attributes of the projects final outcome, i.e. website.

This study attempts to identify the important factors that have a relation with CS, thus giving freelancers an indication of what to look for when working on any web development project posted by any client in a freelance marketplace. Understanding the determinants of CS will also help Pakistani information technology freelancers involved in web development projects and services to increase their project performance, improve their CS rate and increment client following.

This presents the first study on the determinants of CS in web development projects from freelance marketplaces.

Presents over sixty abstracts summarising the 1999 Employment Research Unit annual conference held at the University of Cardiff. Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

Counterproductive work behavior (CWB) imposes significant costs on organizations, thus antecedents of CWB are of particular interest to both practitioners and academics. The authors examine how one’s own narcissism interacts with co-worker narcissism to influence willingness to engage in retaliatory CWB against a co-worker.

The data for this study were obtained from Amazon Mechanical Turk participants and Master of Business Administration students, representing a cross-section of employee representatives.

The authors find that employees expect narcissistic co-workers to engage in continuing future CWB and this, in turn, increases employees' willingness to engage in retaliatory CWB. That is, non-narcissistic employees are provoked to engage in organizationally-destructive behaviors by peers perceived as narcissists. This affect is attenuated by the employee’s own narcissism. Relative to non-narcissists, narcissistic employees find a narcissistic co-worker more likeable, which reduces their willingness to engage in retaliatory CWB against the co-worker.

For corporations and HR managers, this study demonstrates the caution necessary when considering hiring and operational practices. Specifically, non-narcissists demonstrate increased willingness to engage in organizationally-destructive behaviors after interpersonal conflict with a narcissistic co-worker.

The authors extend prior research about interpersonal drivers of CWB, which primarily considered superior-subordinate dyad, by examining the joint effects of individual and co-worker narcissism in peer-to-peer relationships.

The study compares the effects of creativity and digital nativity, with the latter signifying proficiency in digital skills, on enhancing innovation among employees. The research specifically evaluates the impact of creativity and digital nativity on general innovative performance and personal innovativeness using IT (PIIT).

Two studies were conducted. Study 1 surveyed 497 individuals on Prolific using objective measures of general innovative performance and self-report measures of PIIT. Study 2 replicated the same research design on Amazon Mechanical Turk with 336 participants and other-rated measures of PIIT.

Results were consistent across both studies and showed that creativity influenced general innovative performance more than digital nativity. However, digital nativity was a stronger predictor of PIIT, above and beyond the nonsignificant effects of creativity.

This study helps understand the roles that digital nativity and creativity play in general innovative performance and in IT-related innovative performance by providing a relative importance analysis of these components.

We offer guidance to organizations on how to select individuals and assign them to particular tasks depending on digital or general innovative task requirements.

This is the first study to examine the direct comparison of creativity and digital nativity. Although the literature highlights the importance of digital nativity for innovation, our research reveals that creativity is more important for general innovative performance.

This paper aims to present spot pattern welding (SPW) as a scanning strategy for laser-foil-printing (LFP) additive manufacturing (AM) in place of the previously used continuous pattern welding (CPW) (line-raster scanning). The SPW strategy involves generating a sequence of overlapping spot welds on the metal foil, allowing the laser to form dense and uniform weld beads. This in turn reduces thermal gradients, promotes material consolidation and helps mitigate process-related risks such as thermal cracking, porosity, keyholing and Marangoni effects.

304L stainless steel (SS) feedstock is used to fabricate test specimens using the LFP system. Imaging techniques are used to examine the melt pool dimensions and layer bonding. In addition, the parts are evaluated for residual stresses, mechanical strength and grain size.

Compared to CPW, SPW provides a more reliable heating/cooling relationship that is less dependent on part geometry. The overlapping spot welds distribute heat more evenly, minimizing the risk of elevated temperatures during the AM process. In addition, the resulting dense and uniform weld beads contribute to lower residual stresses in the printed part.

To the best of the authors’ knowledge, this is the first study to thoroughly investigate SPW as a scanning strategy using the LFP process. In general, SPW presents a promising strategy for securing embedded sensors into LFP parts while minimizing residual stresses.
