Meta-analysis is the quantitative analysis of results of a research literature. Typically, meta-analysis is paired with a systematic review that fully documents the search process, inclusion and exclusion criteria, and study characteristics. A key feature of meta-analysis is the calculation of effect sizes – metric-free indices of study outcome that allow the mathematical combination of effects across studies. The methodological literature on meta-analysis has grown rapidly in recent years, yielding an abundance of resources and sophisticated analytic techniques. These developments are improvements to the field but can also be overwhelming to new aspiring meta-analysts. This chapter therefore aims to demystify some of that complexity, offering conceptual explanations instead of mathematical formulas. We aim to help readers who have not conducted a meta-analysis before to get started, as well as to help those who simply want to be intelligent consumers of published meta-analyses.
This semi-systematic literature review examines signed language corpus research in the Nordic countries, with a quantitative and qualitative assessment of corpus research. The article first describes some critical components and functionalities of signed language corpora. It then outlines the evolution of Nordic corpus research, highlighting Sweden’s pioneering role and subsequent developments in Finland and Norway. The findings suggest a progression from method-focused publications to those exploring linguistic phenomena within and across (signed) languages. Although the number of research publications is modest, there is a discernible shift towards comparative studies and applications in signed language teaching and learning.
The emergence of smart Product-Service Systems (smart PSS) presents numerous challenges for enterprises. The complexity of designing smart PSS adds to the need for consistent support for manufacturers. Both academia and practitioners highlight the importance of methodological support for successful development of smart PSS. This paper therefore investigates the suitability of existing support for smart PSS. Based on a systematic literature review, 17 support methods are identified and their key characteristics are discussed in the context of real PSS use cases.
This paper presents a mapping of theory use in the design discipline based on the corpus of the published ICED and DESIGN conference papers since 2010. We searched the resulting 4,451 papers for occurrences of theories and compared them with an existing ontology of named theories through natural language processing (NLP). The results yielded a variety of analyses, illustrating, for example, the most-used theories and which disciplines these theories stem from. This paper presents a rich overview of the theories relevant to the design discipline and a novel approach to bibliometric analyses.
In low- and middle-income countries (LMICs), children and families face a multitude of risk factors for mental health and well-being. These risks are even further exacerbated in humanitarian emergencies. However, access to effective mental health services in such settings is severely limited, leading to a large mental health treatment gap. Middle childhood (5–12 years) is a crucial period for human development during which symptoms of emotional distress often emerge, with one in three mental disorders developing prior to age 14. However, there is little evidence of effective psychological interventions for children in this developmental stage, and suitable for implementation within LMICs and humanitarian emergencies. We conducted this evidence review to inform the development of a new intervention package based on existing best practice for this age group, drawing insights from both global and LMIC resources. Our review synthesizes the findings of 52 intervention studies from LMICs and humanitarian settings; 53 existing systematic reviews and meta-analyses covering both LMICs and high-income countries, and 15 technical guidelines. Overall, there is limited high-quality evidence from which to draw recommendations for this age group; however, some promising intervention approaches were identified for children experiencing externalizing and internalizing symptoms, traumatic stress and a combination of difficulties. Several effective interventions utilize cognitive-behavioral techniques for children, in either group or individual format, and incorporate caregiver skills training into treatment, although the findings are mixed. Most evaluated interventions use specialists as delivery agents and are lengthy, which poses challenges for scale-up in settings where financial and human resources are scarce. These findings will inform the development of new psychological interventions for children in this age group with emotional and behavioral difficulties.
The relationship between culture and creativity has sparked the interest of researchers for decades. Although researchers have attempted to establish a connection between culture and creativity, the precise relationship between the two remains ambiguous. The current paper examined extant literature on the subject matter and synthesized the relations between culture and creativity in ideation over the past twenty years. The present study expounds upon the utilized samples, measures implemented to assess creativity and culture, and the study results.
Productive scholars prioritize research and use productive research approaches. How else could some produce ten or more publications per year and hundreds over their career? Productive scholars spend about half their work days focused on research, usually preserving the morning hours for research and writing, because those are their top priority and scholars want to give them their full attention when they are most alert. Productive scholars rarely publish alone. They collaborate on nearly 90 percent of their publications. Benefits of collaboration include the division of labor, multiple viewpoints, quicker outputs, and working on several projects simultaneously. Productive scholars typically juggle a half-dozen projects or more, in various phases of completion. They often seek grants that help them do more and better research. They also find publication opportunities by occasionally mining existing data sets, conducting meta-analyses, and composing literature reviews and conceptual pieces. Their research is marked by good research questions that are feasible to carry out with simple but powerful research designs. Productive scholars are self-regulatory, carefully monitoring progress and adjusting their approach as needed. Still, they occasionally fail, as all do. They are not disheartened, knowing that failure is their catalyst and success guide.
The teaching-learning process, both in general and in the specialty of Music Education, has evolved and its explanatory models have become increasingly complex. In view of current challenges, it is relevant to analyse the elements that are considered necessary to train music teachers to become competent professionals. This study identifies characteristics found in specialised Spanish and international scientific literature on teaching-learning processes in music teacher education, referring to their current state as well as to desirable developments and future prospects. Although a certain overlap among emergent categories in Spain and those in other countries can be observed, we also found differences of degree, as well as interesting divergences.
This article presents a systematic literature review of publications from 2014 to 2021 using “archaeological site” and “climate change” as keywords, in addition to several terms representing forms of stakeholder engagement. Articles were thematically coded to explore trends at the intersection of climate change, archaeology, and local and Traditional stakeholders. Results show that nearly half of the selected publications did not include local and Traditional stakeholder engagement in studies related to climate adaptation planning for archaeological sites. Synthesis of the results with insights gained from other literature on decolonizing archaeology showed that potential reasons for this gap include (1) the academic publishing culture, (2) archaeology as a predominantly Western discipline, and (3) increasingly available tools for climate change adaptation planning for archaeological sites. This article calls on the academic community to consider holistic stewardship using a landscape approach and to use climate change adaptation planning to elevate local and Traditional stakeholder input and values.
Despite increased interest in corporate social irresponsibility (CSI) among business scholars, the current research is still fragmented, its findings lacking a nuanced understanding. We conduct a systematic literature review of 173 journal articles on CSI published in the field of business and synthesize insights regarding the antecedents, consequences, and mechanisms of CSI. We begin by providing a clear definition, distinct types, and the measurement methods of CSI. Then, we provide a comprehensive research framework that demonstrates the three key components of CSI research: antecedent, consequence, and moderating. Building on this, we identify additional specific research methods for each component and apply them to assess and analyze the existing research findings and research gaps concerning CSI. We suggest that scholars pay more attention to (a) the impact of stakeholders on CSI behavior, (b) the different impacts of CSI on firm performance, (c) the relationship among CSI, corporate social responsibility, and firm performance, (d) CSI in the context of emerging economies, and (e) measuring CSI.
Engineering design has proven to be a rich context for applying artificial intelligence (AI) methods, but a categorization of such methods applied in AI-based design research works seems to be lacking. This paper presents a focused literature review of AI-based methods mapped to the different stages of the engineering design process and describes how these methods assist the design process. We surveyed 108 AI-based engineering design papers from peer-reviewed journals and conference proceedings and mapped their contribution to five stages of the engineering design process. We categorized seven AI-based methods in our dataset. Our literature study indicated that most AI-based design research works are targeted at the conceptual and preliminary design stages. Given the open-ended, ambiguous nature of these early stages, these results are unexpected. We conjecture that this is likely a result of several factors, including the iterative nature of design tasks in these stages, the availability of open design data repositories, and the inclination to use AI for processing computationally intensive tasks, like those in these stages. Our study also indicated that these methods support designers by synthesizing and/or analyzing design data, concepts, and models in the design stages. This literature review aims to provide readers with an informative mapping of different AI tools to engineering design stages and to potentially motivate engineers, design researchers, and students to understand the current state-of-the-art and identify opportunities for applying AI applications in engineering design.
Despite the benefits that banks could get from implementing distributed ledger technologies (DLTs), few banks have focused on making full use of it. According to operational experience, DLTs – which are blockchain based in this case – are frequently employed at the level of cryptocurrencies but are seldom used when it comes to banking applications. This chapter aims to provide an overview of the current state of the academic literature on implementing DLT in the banking sector. By providing a comprehensive overview of DLT adoption in the banking sector, this study can contribute to the development of a better understanding of DLT and its potential to transform the banking industry.
In the past decades, numerous publications have been addressing questions of national and European Identity on the micro level. Only few shed light on the contents that constitute these identities in the minds of Europeans. As different meanings of national and European identity are connected to different consequences such as hostile attitudes toward immigrants or Euroskepticism, reviewing attempts to measure these contents in existing cross-national surveys seems to be promising. This research note summarizes relevant literature on whether and which different forms of national and European identity have been found empirically, which specific contents constitute them, and which determinants and consequences of them are relevant. By comparing articles relying on cross-national survey data since 1995, it will be shown that the field of forms of national and European identity involves different operationalizations and numerous methodological concerns. This leads to considerations for further research in the field.
Interreligious relations remain an important dimension of human coexistence and we currently observe an increase in religiously motivated violence and discrimination. Hence, we need to better understand determinants of interreligious peace. Building on a new concept of interreligious peace which includes but exceeds the absence of interreligious physical violence, we provide a systematic review of 83 quantitative empirical studies examining religious determinants of interreligious physical violence, hostile attitudes, threat perceptions, trust, and cooperation. We find that religious ideas foster or hinder interreligious peace depending on their content. Religious identities have negative effects but must be considered in context. Evidence regarding the role of religious practice is mixed and the role of religious actors and institutions remains understudied. Our results show the need for (1) more conceptual clarity, (2) replications in different contexts, (3) research on dimensions of religion beyond identities, and (4) a better integration of different strands of literature.
Population size and geographical range are the key quantitative criteria used by the IUCN to assess the conservation status of a species. However, such information is often incomplete and inconsistent, even for seemingly abundant species. To assess the population and conservation status of Indian primates, we conducted a systematic review of recent research using the searching, appraisal, synthesis and analysis (SALSA) approach. We reviewed a total of 41 studies on Indian primates conducted during the last 2 decades (2000–2021) for information on various parameters that influence their conservation. We found that 20 out of a total of 26 primate species were evaluated for their population status, and the majority of these studies (71%) showed an overall declining population trend. Remarkably, all but one of the studies conducted exclusively within protected areas revealed declining population trends, whereas trends were more variable for primate populations in non-protected areas. Our data indicate that only 27% (n = 7) of Indian primate species have been surveyed or re-surveyed to assess their population status within the last 5 years. Although threats vary in time and space from species to species, 78% of the studies recorded natural system modifications including habitat loss and fragmentation among the main threats to the survival of Indian primates. Most studies on the population status of Indian primates have either been spatially limited or used outdated methods. We recommend that future studies adopt robust techniques to estimate populations and work across larger geographical scales to develop effective management strategies for the conservation of primates in India.
Countries adopted a variety of social policy responses to reduce the social risks exacerbated by the COVID-19 pandemic, which in some cases took the form of institutional reforms. The study of the institutionalisation of emergency responses is relevant to understanding if and how a critical juncture, like the one opened by the pandemic, can generate path dependencies or changes that expand or retrench social protection. This state-of-the-art article offers an overview of how social policy responses to the pandemic have translated to institutional reform across the globe under various types of welfare systems. By conducting a systematic literature review of thirty-nine peer-reviewed journal articles in two leading bibliographic databases (Scopus and Web of Science), this article reviews the available evidence on the responses to the pandemic and their institutional consequences. We find four underlying research clusters regarding the degree of institutionalisation of the social policy responses implemented during the pandemic.
Global resource consumption is steadily rising. One option for stopping this upward trend is to reduce material consumption in general. With economics built for growth, this is not a practical path to pursue. Another recently explored alternative is the paradigm shift from a linear economy to a circular economy. The most common concept among practitioners and academics comprises the 6R's: Reuse, Repair, Refurbish, Remanufacture, Repurpose, and Recycle. In addition to business cases and supply chains that have been adapted to the circular economy, the products themselves must be circular. Developers face the challenge of developing novel products without appropriate experience from previous tasks.
This paper takes up the challenge of gathering relevant methods in the context of circular product development. A classification with regard to the required input data and use case shall help users effectively and efficiently find development methods suitable for their given development task. With the categorization via a product development framework it is pointed out in which phase existing methods support users and where a lack of support occurs.
Requirements represent a central element in product development. The large number of requirements inevitably results in an increased susceptibility to errors, an expenditure of time and development costs. The associated problems motivate the application of Artificial Intelligence in the form of Natural Language Processing (NLP). In Requirements Engineering one main task is the classification of requirements which serves as the input in architectural models e.g. in SysML. In mechanical engineering there is still little overview regarding the interface between requirements classification and modelling. This paper provides an overview of the requirement classes and entities used in the literature and analyses their utilisation in modelling. Existing requirements classes usually do not offer the flexibility to be transferred to other domains. However, basic structures can be adopted from those classifications. This enables a clear assignment of existing classes to object classes in modelling. Resulting from the conducted literature study the observed predominant focus of research on the software industry requires an extension of the existing requirement classes and entities to enable further use and transfer to mechanical engineering.
This chapter offers a primer of the literature on the origins of proportional representation. Subsequent chapters use this literature to illustrate the elements of CHA. It therefore provides the background information to make those illustration easier tofollow.
Lack of access to primary care providers (PCPs) is a significant hurdle to receiving high-quality comprehensive health care and creates greater reliance on emergency departments and walk-in clinics.
Methods:
We conducted a rapid review and analysis of the literature that discusses approaches to increasing access to continuous care for patients with no PCP (‘unattached patients’).
Results:
Five distinct themes across 38 resources were identified: financial incentives for patients and providers, health care organization, policy intervention, virtual care and health information technology (HIT), and medical education. Approaches that increased attachment were primary care models that combined two or more of these and reflected the Patient’s Medical Home (PMH) model.
Conclusions:
Although there are individual initiatives that could allow for temporary relief, long-term and community-wide success lies in designing models of primary care that use multiple tools, meet the needs of the community, and are supported by regional, provincial, and national policies.
