Automatic extraction of 1D barcodes from video scans for drone-assisted inventory management in warehousing applications

The widespread use of barcodes has significantly contributed to accurate, efficient and economic inventory management in warehouses and distribution centres. However, its efficiency has always been limited by the primary method of reading barcodes with a handheld laser scanner. Compared with this reading by line-of-sight at close proximity, vision-based barcode reading algorithms can further improve efficiency, particularly if accompanied by automated data collection platforms such as drones. This paper introduces algorithms that are able to automatically extract barcodes from video data, and verifies their feasibility and promise for inventory management in warehousing applications. Three key techniques corresponding to different recognition levels are proposed: For a known barcode region, a Harris corner detector and Hough transform-based algorithm is applied to quickly estimate the angle by which the frame area needs to rotate to orient the bars vertically for information extraction. Then, the idea of exploiting connectivity and geometry property of barcode areas is proposed to directly recognise multiple barcode regions in a single video frame to eliminate reading difficulties resulting from interactive influence of multiple juxtaposed barcodes, and to save computation time by only processing frame areas of interest for valid barcodes. In addition, a histogram difference-based fast extraction strategy is designed to further improve efficiency by reducing duplicate information processing. Finally, the performance of each technique is evaluated by analysing video data from a large logistics warehouse, demonstrating satisfactory performance in inventory management applications.     

Equal access to hospitality services for guests with mobility impairments under the Americans with Disabilities Act: Implications for the hospitality industry

The hospitality operator's obligation to comply with the ADA has provided the necessary impetus to ensure that hospitality services are provided in a non-discriminatory manner. The ADA requires modification of hospitality policies and procedures to ensure that guests with disabilities are provided services in a manner equivalent to those provided to able-bodied guests. This article provides the hospitality operator with a framework for training front-line employees and offers recommendations for analyzing how current policies and procedures could be modified in a way that limits potential liability as well as more effectively meets the needs of guests with mobility impairments.     

The link between attractiveness of “Extrabrand” attributes and the adoption of innovations

While innovators may rush to purchase many new products, most consumers are more conservative and do not want to buy into fads but purchase only those new products that are viable. How do the majority of consumers make judgments about whether they will adopt an innovation? This article examines the evaluative aspects of adoption as a means for better understanding consumer adoption and the market factors that may influence the success of an innovation. This research introduces a conceptual model that shows how consumers’ evaluation of product category attractiveness affects the adoption decision for really new products. These consumer evaluations are based on the attributes of the product category (“extrabrand” attributes) rather than brand attributes. Results from a test of the model indicate that consumers do use extrabrand attributes to assess the attractiveness of innovative new products.     

Not part of the family? The limits to managing the corporate way in international hotel chains

Companies increasingly seek solutions to the corporate/local dichotomies perceived to be a feature of more traditional approaches to managing across national boundaries. At the human resource level, the rhetoric of transnationalism emphasizes integration being achieved through 'soft' mechanisms, such as corporate culture devices, which encourage all managers to develop an international (for this read corporate) perspective on what they do. In theory, managerial staff are recruited and promoted on a 'best person for the job' basis and national identities are played down. Drawing upon evidence from three international hotel chains (one American, one French and one Swedish), this paper argues that there is a disjuncture between corporate culture devices which assume that they can transcend national origins and the issues of interest and identity which inform the activities and experiences of managers at unit level. The paper suggests that companies need to be aware of the danger of assuming that one can be trained to be 'one of the family'. Rather, we argue that local managers are potentially disadvantaged in terms of career progression as managers from the parent country utilize criteria of acceptability informed by processes of socialization which are more institutionally embedded and derived than has been assumed.     

National culture and labour-market flexibility

This paper develops a cultural explanation for labour-market flexibility, building on the work of Lipset. Using Hofstede's conceptual framework for categorizing national cultures, certain hypotheses are derived concerning the association of various labour-market institutions and rigidities connected with employment, pay bargaining the treatment of the unemployed, and Hofstede's dimensions of national culture. These hypotheses are tested on data for OECD countries, using ordinary least squares regression. The results demonstrate a strong statistical association between Hofstede's cultural indices and the various labour-market rigidities. In particular, there is a strong inverse relationship between Hofstede's MAS variable and all our labour flexibility variables. Cultural values reflecting feminine gender structuring appear to be strongly associated with labour-market inflexibility. There is also a strong statistical association between scores on the UAI dimension, and employment rigidities and pay-bargaining practices. Cultural attitudes to power inequalities as reflected in the PDI index inversely related to rigidities in pay-bargaining practices. While the results demonstrate only statistical associations, they are suggestive of the possibility that culture plays more determining role. This has important implications for deregulation/regulation strategies.     

Incentives and targets in hospital care: Evidence from a natural experiment

Performance targets are commonly used in the public sector, despite their well known problems when organisations have multiple objectives and performance is difficult to measure. It is possible that such targets may work where there is considerable consensus that performance needs to be improved. We investigate this possibility by examining the response of the English National Health Service to high profile waiting time targets. We exploit a natural policy experiment between two countries of the UK (England and Scotland) to establish the global effectiveness of the targets. We then use a within-England hospital analysis to confirm that responses vary by treatment intensity and to control for differences in resources which may accompany targets. We find that targets met their goals of reducing waiting times without diverting activity from other less well monitored aspects of health care and without decreasing patient health on exit from hospital.     

MEDICARE AND INEQUALITIES IN HEALTH OUTCOMES: THE CASE OF BREAST CANCER

This article evaluates whether expanding Medicare to cover those between ages 55 and 64 will improve the health status of these near-elderly individuals. We compare the experiences of near-elderly and elderly women with breast cancer and pay special attention to those demographic groups traditionally thought to be disadvantaged. Using unique individual-level data from the National Cancer Institute, we find that expanding Medicare does not improve the probability that a black woman will have her cancer diagnosed early. However, if she does happen to be diagnosed early, a discretE-time hazard model of survival finds that the price effects of insurance will improve her odds of survival.
