The purpose of this paper is to provide a profile of the novelist Charles Dickens.

Several biographies and articles about the life of Charles Dickens were examined, to see if there was evidence that he experienced mental health problems.

While Dickens has been acclaimed for his ability to authentically portray the living conditions of the poor in the nineteenth-century Britain, there is comparatively little historical record of the fact that he may have experienced bipolar disorder. This paper suggests that he displayed many of the characteristic symptoms of bipolar.

The story of Dickens’ own childhood is an amazing example of personal resilience. It no doubt enhanced the quality of his writing, but it may also have “sown the seeds” of a later mental illness.

So much attention has been focused on the colourful characters from Dickens’ novels, but little on the problems of the man himself.

The story of Charles Dickens is as fascinating as any of the fictional characters he created, if not even more intriguing. His story confirms the link between writers, creativity and mood disorders.

Given the huge attention and worldwide acclaim paid to the books of Charles Dickens, which have inspired numerous films as well as musicals, it is surprising how little attention has been paid to the author himself and his struggles with mental illness.

Pilot upgrade training is critical to aircraft and passenger safety. This study aims to identify variances in the US Air Force C-130J pilot upgrade training based on geographic location and provide a model to enhance policy that will impact future pilot training efforts that lower cost and increase operator quality and proficiency.

This research employed a mixed-method approach. First, the authors collected data and analyzed 90 C-130J pilots' aviation records and then contextualized this analysis with interviews of experts. Finally, the authors present a modified version of Six Sigma's define–measure–analyze–improve–control (DMAIC) that identifies and reduces the variances in C-130J pilot training, translating into higher quality outcomes.

The results indicate significant statistical variances across geographically separated C-130J pilot training organizations. This leads some organizations to have higher proficiency levels in specific tasks and others with comparative deficiencies. Additionally, the data analysis in this study enabled a recommended number of flight hours in several distinct categories that should be obtained before upgrading a pilot to aircraft commander to enhance standards.

This research was limited to C-130J pilot upgrades, but these results can be implemented within any field that utilizes hours as a measure of experience. Implications from this research can be employed to scope policy that will influence pilot training requirements across all airframes in civilian and military aviation.

This research proposes a process improvement methodology that could be immediately implemented within the C-130J community and, more importantly, in any upgrade training where humans advance into higher echelons of a profession.

This paper aims to explore effective supply chain principles, through the theory of transaction cost economics, as measures to improve current contingency pharmaceutical item shortfalls in the Air Force Medical Service (AFMS) Contingency Pharmaceutical Programme.

In this research, AFMS contingency pharmaceutical data was collected from various databases, including the Joint Medical Asset Repository, Medical Contingency Requirements Workflow and the Medical Requirements List. Through the methodology of cost-benefit analysis, alternative sourcing and fulfilment practices are evaluated.

The findings of this research indicate that the application of centralized purchasing principles, in an effort to leverage prime vendor contract fill rates for shortage items, can lead to 12%–17% increases in pharmaceutical material availability across the programme.

This research clearly shows that consolidating demand for shortage items across Active Duty War Reserve Material assemblages, though applications of centralized purchasing principles that leverage prime vendor contract fill rates, can lead to substantial increases in material availability at costs that justify the calculated benefits.

Forecasting techniques improve supply chain resilience by ensuring that the correct parts are available when required. In addition, accurate forecasts conserve precious resources and money by avoiding new start contracts to produce unforeseen part requests, reducing labor intensive cannibalization actions and ensuring consistent transportation modality streams where changes incur cost. This study explores the effectiveness of the United States Air Force’s current flying hour-based demand forecast by comparing it with a sortie-based demand forecast to predict future spare part needs.

This study employs a correlation analysis to show that demand for reparable parts on certain aircraft has a stronger correlation to the number of sorties flown than the number of flying hours. The effect of using the number of sorties flown instead of flying hours is analyzed by employing sorties in the United States Air Force (USAF)’s current reparable parts forecasting model. A comparative analysis on D200 forecasting error is conducted across F-16 and B-52 fleets.

This study finds that the USAF could improve its reparable parts forecast, and subsequently part availability, by employing a sortie-based demand rate for particular aircraft such as the F-16. Additionally, our findings indicate that forecasts for reparable parts on aircraft with low sortie count flying profiles, such as the B-52 fleet, perform better modeling demand as a function of flying hours. Thus, evidence is provided that the Air Force should employ multiple forecasting techniques across its possessed, organically supported aircraft fleets. The improvement of the forecast and subsequent decrease in forecast error will be presented in the Results and Discussion section.

This study is limited by the data-collection environment, which is only reported on an annual basis and is limited to 14 years of historical data. Furthermore, some observations were not included because significant data entry errors resulted in unusable observations.

There are few studies addressing the time measure of USAF reparable component failures. To the best of the authors’ knowledge, there are no studies that analyze spare component demand as a function of sortie numbers and compare the results of forecasts made on a sortie-based demand signal to the current flying hour-based approach to spare parts forecasting. The sortie-based forecast is a novel methodology and is shown to outperform the current flying hour-based method for some aircraft fleets.

The purpose of this research is to explore the utility of autonomous transport across two independent airframe maintenance operations at a single location.

This study leveraged discrete event simulation that encompassed real-world conditions on a United States Air Force flight line. Though the Theory of Constraints (TOC) lens, a high-demand, human-controlled delivery asset is analyzed and the impact of introducing an autonomous rover delivery vehicle is assessed. The authors’ simulations explored varying numbers and networks of rovers as alternative sources of delivery and evaluated these resources’ impact against current flight line operations.

This research indicates that the addition of five autonomous rovers can significantly reduce daily expediter delivery tasks, which results in additional expertise necessary to manage and execute flight line operations. The authors assert that this relief would translate into enhancements in aircraft mission capable rates, which could increase overall transport capacity and cascade into faster cargo delivery times, systemwide. By extension, the authors suggest overall inventory management could be improved through reduction in transportation shipping time variance, which enhances the Department of Defense’s overall supply chain resilience posture.

When compared against existing practices, this novel research provides insight into actual flight line movement and the potential benefits of an alternative autonomous delivery system. Additionally, the research measures the potential savings in the workforce and vehicle use that exceeds the cost of the rovers and their employment.

Deals with surveyor variability, in terms of identifying defects, when undertaking surveys of residential properties. It is based on a sample of 38 surveyors who took part in a large‐scale house condition survey (LSHCS). Seeks to quantify the extent of the variability of surveyors in LSHCS, and proposes methods to try to reduce the incidence of variability. Discusses not only the variability of surveyors in identifying defects to building elements, but also their perceptions of lifetimes for building elements. Concludes that the accuracy of data collection (i.e. the process of surveying a dwelling) is paramount if the information derived from the data is to be of value to the parties described. Also concludes that a mechanism for assessing individual surveyor’s variable tendencies needs to be developed to try to reduce the impact of variability at the survey data analysis stage.

WHILE there is no doubt that the system of issuing books at “net” prices is of great benefit to booksellers, there is also no doubt that, unless care is taken, it is a serious drain upon a limited book‐purchasing income. A few years ago the position had become so serious that conferences were held with a view to securing the exemption of Public Libraries from the “net” price. The attempt, as was perhaps to be expected, failed. Since that time, the system has been growing until, at the present time, practically every non‐fictional book worth buying is issued at a “net price.”

This research paper aims to examine two hybrid models of logistics service quality (LSQ) and its influence on satisfaction, loyalty and future purchase intention in a business-to-consumer (B2C) e-commerce context. This study extends the literature for LSQ by incorporating the second-order assurance quality construct, which comprises personnel contact quality, order discrepancy handling and order returns, into one of the hybrid models.

A survey-based approach is used to collect data. Participant responses to questions concerning multiple LSQ dimensions and behavioral perceptions from their most recent online shopping experience are measured using structural equation modeling.

Findings highlight the importance of including a second-order construct assurance quality as a more explanatory model. Results illustrate that online ordering procedures and assurance quality impact customer satisfaction more than other prominent LSQ dimensions. Furthermore, the findings revealed a customer loyalty is a partial mediator between customer satisfaction and future purchase intention. This underscores the significance of improved logistics services as a competitive edge for e-commerce retailers.

Implications are limited to the e-commerce B2C domain.

The findings of this study underscore critical LSQ dimensions that garner greater satisfaction and retention in the online shopping experience. The results indicate that the effective and efficient handling of the initial order and any order problem significantly influences customer satisfaction and reaps the long-term benefits of customer retention.

The authors present and empirically test a hybrid model of LSQ in a B2C e-commerce domain that captures many of the important elements of the customer experience as espoused in the literature.

Antonioni, Berger, Magritte and Sontag, with their respective challenges to our perceptions of what is real and unreal, set the scene for a discussion of the tension between current policies and norms in higher education systems and the increasingly important need to introduce true interdisciplinarity in university programmes – specifically, here, with regard to the role of the humanities in business-related courses. It is argued that uncertainty and imperfection are key signposts to creativity and innovation. Uncertainty demands the constant search for possibility; imperfection provides the constant opportunity to improve and is therefore the inspiration for innovation. In an exploration focussing principally on the various potentialities of the study of literature, it is suggested that many initiatives to introduce the arts into non-humanities programmes have a common and significant limitation in that they are defined by a specific purpose – by an understandable and, in our current higher education environments, an inevitable need to specify what ‘impact’ the intervention will have on the skills and employability of the student. However, something much more radical is needed if what George Eliot called the ‘vital connections of knowledge’ are to be truly made, and the radical adjustment required runs directly counter to a culture that is dominated by the compulsion to demonstrate impact, set measurable targets and prioritize practical application.
