The purpose of this project was to compare the cost of transportation engineering design services provided by private contractors versus services provided by state transportation agency staff for the Louisiana Department of Transportation and Development (LaDOTD). Due to shrinking budgets, staff cuts, and a trend toward privatization, state transportation agencies now outsource the majority of the services they provide. The merits of doing so, however, have been difficult to discern for lack of “apples-to-apples” comparisons. For engineering design services, this problem is particularly acute due to the uniqueness of many projects (e.g., a bridge over the Mississippi river). A simulation approach was used in this study to make “apples-to-apples” comparisons for 39 design projects, 22 in-house projects and 17 consultant projects. For each in-house design project, the cost was estimated had the work been done by a consulting firm. Similarly, for each consultant design project, the cost was estimated had the work been done by in-house staff. The result of the study was that in-house design costs were cheaper by an average of 17 to 19 percent.

The purpose of this paper is to question the extent to which Sub-Saharan African cities are progressing towards promoting pro-poor economies through pro-poor tourism (PPT). It specifically examines how African cities are resilient towards attaining sustainable urban tourism destinations in light of high urbanization.

The methodological framework is interpretive in nature and qualitative in an operational form. It uses meta-synthesis to evaluate the causal relationships observed within Sub-Saharan African pro-poor economies to enhance PPT approaches, using Accra, Ghana, Johannesburg, South Africa, and Harare, Zimbabwe, as case studies.

Tourism development in Sub-Saharan Africa has been dominantly underpinned by neoliberal development strategies which threaten the sustainability of tourism in African cities.

The study is limited to three Sub-Saharan African countries. Further studies may need to be done in other developing countries.

It argues for good governance through sustainability institutionalization which strengthens the regulative mechanisms, processes and organizational culture. Inclusive tourism approaches that are resilient-centered have the potential to promote urban tourism in Sub-Saharan African cities. These findings contribute to the building of strong and inclusive Institutions for Sustainable Development in the Sub-Saharan African cities to alleviate poverty.

These findings contribute to the building of strong and inclusive institutions for sustainable development in the Sub-Saharan African cities to alleviate poverty.

The “poor” are always within the communities, and it takes a community to minimise the impact of poverty among the populace. The study is conducted at a pertinent time when most African government’s development policies are pro-poor driven. Though African cities provide opportunities of growth, they are regarded as centres of high inequality.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

The purpose of this paper is to investigate the implementation challenges of one of lean construction’s recent tools, the last planner system (LPS), by exploring issues in the New Zealand construction sector to identify potential areas for improvement. To achieve this aim, the study formulated two objectives: to present the challenges in LPS use and to explore solutions by using an Excel spreadsheet for facilitating LPS applications.

The study drew primarily upon a case study approach. A fieldwork study and document analysis of a New Zealand construction project were conducted with an extensive literature review undertaken on the LPS concept.

The findings revealed that although an automated spreadsheet could be a simple and inexpensive option for using the LPS, data collection, storage and transfer into the spreadsheet could significantly influence the reliability of the LPS outcomes. Most data utilisation challenges were found to occur around the three data sets included in the weekly work plan (WWP). The study presented several automation solutions which had been applied to overcome data utilisation challenges.

Among the first of its kind in the construction industry, this study, with its first-hand account of an organisation which uses the lean paradigm, provides an in-depth insight into LPS tool implementation. The study extends the current body of knowledge by unearthing the challenges of LPS integration into construction activities and presenting efforts undertaken in a construction case project to overcome relevant issues. This adds value by enhancing the reliability of the LPS and, consequently, the effectiveness of its implementation in practical terms.

The purpose of this study is to raise the issue of contemporary retromania with marketing historians.

This is a reflective essay combining personal experiences with empirical exemplars.

It is found that retromarketing is a subject requiring scholarly scrutiny. The commodification of the past is increasingly prevalent and marketing historians are ideally placed to lead the discussion.

As yestermania is unlikely to evaporate anytime soon, it provides rich, socially and managerially relevant pickings for marketing historians.

Aside from the scurrilous suggestion that historians should get out of the dusty archives, it argues that originality is overrated.

WHEN YOU meet people for the first time and they ask what you do, do you ever hesitate about telling them you're a librarian? Do you ever qualify your self‐description with some such phrase as ‘can't you tell by looking at me?’ or ‘I don't just stamp books you know’? Do you sometimes feel diffident about describing your work? I do. The reason I react in this way is that I know people outside our information world think they know very well what we do, but in fact have very little idea. We seem to have a very strong popular image which it is difficult if not impossible to shake off.

The purpose of this paper is to provide a model of consumer response to music in broadcast commercials outlining four variables (listening situation, musical stimulus, listener characteristics, and advertising processing strategy) that affect a consumer's attitude toward the advertising music (A_am).

The paper takes the form of an integrative review of the relevant literatures from the psychology of music, marketing, and advertising.

A_am can be positively but also negatively influenced by many factors. Only some of these variables are employed in any typical study on consumer response to music, which may account for some conflicting findings.

The paper discusses factors for effectively using commercial music to affect A_am, with special focus on advertising processing strategy. Advertisers are urged to exercise extreme caution in using music and to always pretest its use considering factors identified in this paper. The paper suggests ways in which the model can guide future research.

The paper integrates diverse literatures and outlines the major variables comprising our model of consumer response to advertising music. Advertisers can use these variables as a checklist for factors to consider in selecting ad music.

Although resilience is heavily studied in both the healthcare and organizational change literatures, it has received less attention in healthcare information technology (HIT) implementation research. Healthcare organizations are consistently in the process of implementing and updating several complex technologies. Implementations and updates are challenged because healthcare workers often struggle to perceive the benefits of HITs and experience deficiencies in system design, yet bear the brunt of the blame for implementation failures. This combination implores healthcare workers to exercise HIT resilience; however, how they talk about this construct has been left unexplored. Subsequently, this study explores healthcare workers' communicative constitution of HIT resilience.

Twenty-three physicians (N = 23), specializing in oncology, pediatrics or anesthesiology, were recruited from one healthcare organization to participate in comprehensive interviews during and after the implementation of an updated HIT system DIPS.

Thematic analysis findings reveal physicians communicatively constituted HIT resilience as their (1) convictions in the continued, positive developments of newer HIT iterations, which marked their current adaptive HIT behaviors as temporary, and (2) contributions to inter-organizational HIT brainstorming projects in which HIT designers, IT staff and clinicians jointly problem-solved current HIT inadequacies and created new HIT features.

Offering both practical for healthcare leaders and managers and theoretical implications for HIT and resilience scholars, this study's results suggest that (1) healthcare leaders must work diligently to create a culture of collaborative HIT design in their organization to help facilitate the success of new HIT use, and (2) information technology scholars reevaluate the theoretical meaningfulness a technology's spirit and reconsider the causal nature of a technology's embedded structures.

In the past few decades, the content-based image retrieval (CBIR), which focuses on the exploration of image feature extraction methods, has been widely investigated. The term of feature extraction is used in two cases: application-based feature expression and mathematical approaches for dimensionality reduction. Feature expression is a technique of describing the image color, texture and shape information with feature descriptors; thus, obtaining effective image features expression is the key to extracting high-level semantic information. However, most of the previous studies regarding image feature extraction and expression methods in the CBIR have not performed systematic research. This paper aims to introduce the basic image low-level feature expression techniques for color, texture and shape features that have been developed in recent years.

First, this review outlines the development process and expounds the principle of various image feature extraction methods, such as color, texture and shape feature expression. Second, some of the most commonly used image low-level expression algorithms are implemented, and the benefits and drawbacks are summarized. Third, the effectiveness of the global and local features in image retrieval, including some classical models and their illustrations provided by part of our experiment, are analyzed. Fourth, the sparse representation and similarity measurement methods are introduced, and the retrieval performance of statistical methods is evaluated and compared.

The core of this survey is to review the state of the image low-level expression methods and study the pros and cons of each method, their applicable occasions and certain implementation measures. This review notes that image peculiarities of single-feature descriptions may lead to unsatisfactory image retrieval capabilities, which have significant singularity and considerable limitations and challenges in the CBIR.

A comprehensive review of the latest developments in image retrieval using low-level feature expression techniques is provided in this paper. This review not only introduces the major approaches for image low-level feature expression but also supplies a pertinent reference for those engaging in research regarding image feature extraction.
