Creating a Comprehensive Review of the Literature

Research normally begins by doing a “review of the literature” to see what has already been written and to determine “gaps” in the literature for further research. This handout reviews ways to search for books, scholarly articles, dissertations, and grey literature on any topic using our library subscription resources

Single-Father Families: A Review of the Literature

The number of children residing in single-father families in the United States quadrupled as a proportion of children\u27s living arrangements during the past few decades of the 20th century. Research on single fathers also increased and changed in nature. This article is a review of the research on single fathers and their families from the 1970s until recently, focusing on modifications in methodology and theoretical underpinnings. In general, research on single-father families evolved from qualitative studies focused on the well-being of single fathers to quantitative studies focusing on child outcomes and within-group variation among single fathers. Research also moved from descriptive studies to those testing gender and microstructural theories. This article also summarizes the main findings on single fathers and concludes with directions for future research

Software fault characteristics: A synthesis of the literature

Faults continue to be a significant problem in software. Understanding the nature of these faults is important for practitioners and researchers. There are many published fault characteristics schemes but no one scheme dominates. Consequently it is difficult for practitioners to effectively evaluate the nature of faults in their software systems, and it is difficult for researchers to compare the types of faults found by different fault detection techniques. In this paper we synthesise previous fault characteristics schemes into one comprehensive scheme. Our scheme provides a richer view of faults than the previous schemes published and presents a comprehensive, unified approach which accommodates the many previous schemes. A characteristics-based view of faults should be considered by future researchers in the analysis of software faults and in the design and evaluation of new fault detection tools. We recommend that our fault characteristics scheme be used as a benchmark scheme

Costs of Interchange: A Review of the Literature.

Interchange within mode influences the demand for that mode through the effect it has on time spent waiting, time spent transferring between vehicles and the inconvenience and risks involved, whilst interchange between modes has additional implications in terms of information provision, through ticketing and co-ordination. The valuation and behavioural impact of each of these factors will vary with an individual’s socio-economic and trip characteristics as well as with the precise features of the interchange. A reduction in the costs of interchange brought about by an improvement to any of the above factors will lead to increasingly ‘seamless journeys’ and such benefits which must be quantified. Indeed, this issue has been identified as an area of key importance in the Government’s Transport White Paper (DETR, 1998a) which states: Quick and easy interchange is essential to compete with the convenience of car use. This message was reiterated by the draft guidance for Local Transport Plans (DETR, 1998b), which called for: more through-ticketing, better connections and co-ordination of services, wider availability of information and improved waiting facilities. Rather than being perceived simply as a barrier to travel, quality interchange is now also being regarded as an opportunity to create new journey opportunities. A recent report on the subject of interchange (Colin Buchanan and Partners, 1998) claimed that : It will become more sensible and economic to base public transport networks around the concept of interchange rather than the alternative of trying to avoid it. whilst in response to the diffuse travel patterns made possible by increased car availability, CIT (1998) commented: people should readily be able to complete a myriad of journeys by changing services (and modes) if a through facility is not available. Ease of interchange should be something we take for granted. Regardless of the precise direction in which transport policy and public transport provision develop, practical constraints and the fact that the most heavily trafficked routes tend to have through services places limitations on the extent to which the need to interchange can be reduced whilst no matter how fully integrated different modes of transport are the need to transfer between them cannot be removed. In contrast, the need to change would inevitably increase with the adoption of a practice of building networks around interchange to create new journey opportunities. However, there is considerable scope to improve existing interchange situations or to design new ones which impose minimum costs. Although previous empirical research has focused on the need to interchange or not, and this remains important, it is essential that research is also directed at improvements which facilitate interchange.The aims of this study, as set out in the terms of reference, are centred around the demand side response to interchange rather than the technical supply side issues relating to improving interchange and integration which have been covered in other studies (Colin Buchanan and Partners, 1998; CIT, 1998). The objectives are: to explore the extent to which the reality and perception of interchange deters public transport use, absolutely and in relation to other deterrents to investigate how public transport users perceive interchange; how they make choices and trade-offs in travel cost and time and the influence of interchange attributes (e.g. information, through ticketing) on those choices to assess which components of interchange act as the greatest deterrent to travel to investigate the extent to which interchange penalties vary according to journey purpose, distance and time of travel (or other factors)

A Critical Review of the Literature and Practice of Competency Modelling

Competency models are commonly practiced today in many organizations as they lead to significant human resource development that provides organizations with a competitive edge. Because of their immense importance, measurement and modelling of competencies has become an important research field. However, despite the extensive research, there are large research gaps regarding the empirical knowledge and applicability of competency models. This article presents a critical review of competency modelling literature and practice from the major perspectives (including applied, academic, and professional) in an attempt to shed additional light on the advantages and practices of competency modelling, as well as outlining current challenges in such a vibrant domain. The intention, in this article, was to build a coherent argument with an objective of illustrating the effective use, as well as deficiencies in this domain based on aggregated experiences of many authors across many years and settings. The author explicitly acknowledges that the approach for this critical review has many limitations, since it is experience-based rather than empirically based. Yet, it is believed that this article may provide a framework that can lead to a solid investigation of competency modelling with more rigor than they have been afforded to date.     Keywords: Competency Modelling, Behavioural Paradigm, Job Analysis, Performance, NViv

Funding Alternative Education Pathways: A Review of the Literature

This review drew upon anecdotal and empirical research and reports from a variety of fields, including education and school finance theory, alternative education pathways, nonprofit management, and charter school finance. This does not pretend to be a comprehensive thesis on either alternative education pathways or education financing, but rather a point of departure for future discussions. The review is loosely organized according to three aspects of resource allocation presented by Brent, Roellke, & Monk (1997), including fund origination, access and allocation, and utilization

Narcolepsy and emotional experience: a review of the literature

Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, and sleep paralysis. This disease affects significantly the overall patient functioning, interfering with social, work, and affective life. Some symptoms of narcolepsy depend on emotional stimuli; for instance, cataplectic attacks can be triggered by emotional inputs such as laughing, joking, a pleasant surprise, and also anger. Neurophysiological and neurochemical findings suggest the involvement of emotional brain circuits in the physiopathology of cataplexy, which seems to depending on the dysfunctional interplay between the hypothalamus and the amygdala associated with an alteration of hypocretin levels. Furthermore, behavioral studies suggest an impairment of emotions processing in narcolepsy-cataplexy (NC), like a probable coping strategy to avoid or reduce the frequency of cataplexy attacks. Consistently, NC patients seem to use coping strategies even during their sleep, avoiding unpleasant mental sleep activity through lucid dreaming. Interestingly, NC patients, even during sleep, have a different emotional experience than healthy subjects, with more vivid, bizarre, and frightening dreams. Notwithstanding this evidence, the relationship between emotion and narcolepsy is poorly investigated. This review aims to provide a synthesis of behavioral, neurophysiological, and neurochemical evidence to discuss the complex relationship between NC and emotional experience and to direct future research

Acute psychiatric ward rules: a review of the literature

This literature review forms a background element of a comparative study of two acute psychiatric wards in the East End of London. The research focused on ward rules as a means of investigating the relationship between the flexibility/inflexibility of ward nursing regimes and patient outcomes. Previous studies identified a relationship between ward rules and patient aggression. Other studies identified a link between absconding by inpatients and nurses’ attitudes towards rule enforcement. However, an in-depth exploration of psychiatric ward rules from the perspective of nurses and patients has not been undertaken previously

Review of the literature on reference pricing

This paper reviews the literature on reference pricing (RP) in pharmaceutical markets. The RP strategy for cost containment of expenditure on drugs is analyzed as part of the procurement mechanism. We review the existing literature and the state-of-the-art regarding RP by focusing on its economic effects. In particular, we consider: (1) the institutional context and problem-related factors which appear to underline the need to implement an RP strategy; i.e., its nature, characteristics and the sort of health care problems commonly addressed; (2) how RP operates in practice; that is, how third party-payers (the insurers/buyers) have established the RP systems existing on the international scene (i.e., information methods, monitoring procedures and legislative provisions); (3) the range of effects resulting from particular RP strategies (including effects on choice of appropriate pharmaceuticals, insurer savings, total drug expenditures, prices of referenced and non-referenced products and dynamic efficiency; (4) the market failures which an RP policy is supposed to address and the main advantages and drawbacks which emerge from an analysis of its effects. Results suggest that RP systems achieve better their postulated goals (1) if cost inflation in pharmaceuticals is due to high prices rather than to the excess of prescription rates, (2) when the larger is the existing difference in prices among equivalent drugs, and (3) more important is the actual market for generics.Reference pricing, pharmaceutical expenditure, generic drugs, drug patents
