Hybrid propulsion technology program. Volume 1: Conceptional design package

A concept design study was performed to configure two sizes of hybrid boosters; one which duplicates the advanced shuttle rocket motor vacuum thrust time curve and a smaller, quarter thrust level booster. Two sizes of hybrid boosters were configured for either pump-fed or pressure-fed oxygen feed systems. Performance analyses show improved payload capability relative to a solid propellant booster. Size optimization and fuel safety considerations resulted in a 4.57 m (180 inch) diameter large booster with an inert hydrocarbon fuel. The preferred diameter for the quarter thrust level booster is 2.53 m (96 inches). As part of the design study critical technology issues were identified and a technology acquisition and demonstration plan was formulated

The role of Information Technology in the Personnel Department: HRM in the Knowledge economy

With the increasing possibilities of providing services to employees through Internet and Intranet applications, Human Resource professionals just need to click once or twice and a specially designed HR website leads to the required information. Employees would no longer be held responsible for the operational and administrative HR activities. Electronic-Human Resource Management (e-HRM) is the engine for pushing down the costs of any company and making it profitable. Information technology has been identified as an impetus of HR’s transition to becoming a strategic business partner. In this study, we extend this work one step further and explore the role of information technology in shaping the competency requirements of HR professionals. Key words: e-HRM; Human Resource Information Systems Résumé: Avec une possibilité croissante de fournir des services aux employés via les applications d'Internet et d'Intranet, les professionnels des ressources humaines suffisent de cliquer une ou deux fois et un site web spécialement conçu pour les RH peut les conduire à l'information requise. Les employés ne seront plus tenus responsables pour les activités opérationnelles et administratives des RH. La gestion des ressources humaines électronique (GRH électronique) est le moteur pour réduire les coûts de la compagnie et la rendre rentable. Les technologies de l'information ont été identifiées comme un nouvel élan de la transition des ressources humaines à devenir un partenaire d'affaires stratégique. Dans cette étude, nous étendons ce travail un peu plus loin et explorons le rôle des technologies informatiques dans l'élaboration des exigences relatives aux compétences des professionnels des RH.

Market Characteristics, Intra-Firm Coordination, and the Choice of Human Resource Management Systems: Evidence from New Japanese Data

This paper explores theoretically and empirically potentially important yet often-neglected linkage between task coordination within the organization and the structure of organization and bundling of HRMPs (Human Resource Management Practices). In so doing, we also provide fresh insights on the interplay between the firm’s technological and output market characteristics and its choice of HRMP system. We begin with constructing a team-theoretic model and derive three task coordination modes: vertical control, horizontal coordination, and hybrid coordination. The model provides rich implications about complementarity involving task coordination modes, HRMPs, training and hiring, and management strategies, and illustrates how such complementarity is affected by the firm’s technological and output market conditions. Guided by the theoretical exploration, we analyze unique data from a new survey of Japanese firms which provide for the first time data on newer forms of HRMPs adopted by Japanese firms (such as cross-functional offline teams and self-managed online teams). One novel finding (which is consistent with the theory) is that the adoption of both self-managed online teams and cross-functional offline teams usually arises in firms with shop-floor committees while the introduction of cross-functional offline teams alone often takes place in firms with joint labor-management committees. We also confirm implications from our theory that firms in more competitive markets are more likely to adopt both types of teams while firms facing more erratic price movement tend not to adopt self-managed online teams.

Induced Genetic Variations in Fruit Trees Using New Breeding Tools : Food Security and Climate Resilience

Fruit trees provide essential nutrients to humans by contributing to major agricultural outputs and economic growth globally. However, major constraints to sustainable agricultural productivity are the uncontrolled proliferation of the population, and biotic and abiotic stresses. Tree mutation breeding has been substantially improved using different physical and chemical mutagens. Nonetheless, tree plant breeding has certain crucial bottlenecks including a long life cycle, ploidy level, occurrence of sequence polymorphisms, nature of parthenocarpic fruit development and linkage. Genetic engineering of trees has focused on boosting quality traits such as productivity, wood quality, and resistance to biotic and abiotic stresses. Recent technological advances in genome editing provide a unique opportunity for the genetic improvement of woody plants. This review examines application of the CRISPR-Cas system to reduce disease susceptibility, alter plant architecture, enhance fruit quality, and improve yields. Examples are discussed of the contemporary CRISPR-Cas system to engineer easily scorable PDS genes, modify lignin, and to alter the flowering onset, fertility, tree architecture and certain biotic stresses.Peer reviewe

Implications of Virtual Interviews as a Global Recruitment Tool

Global business environments have become increasingly competitive. Consequently, businesses are seeking newer methods to improve efficiency, reduce costs, market new products faster, and retain customers for the long haul. One of the methods that has emerged to aid businesses accomplish all these goals is computer-mediated communication (CMC) applications. Computer-mediated communication applications in employment interviewing have received some attention from businesses since the emergence of the Internet. Existing technology makes it feasible for employers to screen and interview prospective employees without these applicants leaving their homes globally. Current trends suggest that electronic recruiting will constitute a significant portion of human resource management activity in the future. This paper discusses (1) the employment interview and its role in virtual recruiting, (2) virtual interviewing within the framework of computer-mediated communication (CMC), (3) organizational applications of virtual recruiting systems, (4) virtual organizational communication and how its attributes lend themselves to implementing virtual interviewing in organizations, (5) the relationship between virtual organizational communication and virtual recruitment , (6) Internet-basd interviewing in the context of transaction economics, (7) whether or not virtual interviews will replace traditional interviews, and (8) managerial implications of virtual recruitment and interviewing in organizations. This paper concludes by proposing areas for further research

A strategic decision support tool for shipyard production performance evaluation and support in budgeting for performance improvement

This research has been motivated by a demand from industry for an efficient decision support tool for shipyards to select and implement the right performance improvement strategies that fit the nature of their own business. This research project has developed a strategic approach, named shipyard production performance management (SPPM), to support shipyards to optimise their performance management strategy. The key functionalities of the algorithm include performance evaluation and budget optimisation for planning the improvement activities. SPPM is designed to evaluate the production performance using an advanced approach based on Key Performance Indicator (KPI) principles. The production performance of the shipyard is reviewed comprehensively from seven aspects, including Health and Safety, economic, environmental, technical, human resource, security and supply chain management. In total, there are 30 KPIs with their calculation details defined to measure the performance from these perspectives. Accordingly, the hotspots can be identified to prioritise the focus for the future improvement. This is not only to select the suitable emerging technology, but also to determine the capital investment required for such activities. How to optimise the budget for performance improvement then becomes the next question for which the shipyards need to find a solution. The budget optimisation function in SPPM has two functions named Performance Based Budgeting (PBB) and Budget Allocation Optimisation (BAO). PBB defines the total budget required with its allocation via adopting the framework of Cooperate Performance Management (CPM), while BAO applies when the total available fund is restricted. Depending on the decision context and data availability, the BAO can be performed by different calculation methods, including multi-criteria decision analysis (MCDA), utility theory and mathematical programming, for which procedures have been developed in this research. The development of SPPM is supported by a comprehensive knowledge-based that contains various well-established theories and models, practical experience shared by shipyards as well as numerous relevant researches in the field. More than just direct usage of this knowledge base, SPPM is the extension and combination of various existing theories or the application of these theories in new fields. Benefited from involvement of the shipyards, the developed algorithm has strong practicality, which has been developed as the extracted essence from intensive researches, taking into account of usefulness in measuring performance of each PPI, the data availability of the input parameters, and the level of acceptability and comprehensibility of the algorithm for users, etc. SPPM evaluate the production performance from multiple angles, such as technical, socioeconomics, sustainability, collaboration with third parties, and all the supportive and administrative activities at the shipyard, etc., and provide step-by-step instruction for the assessment. Besides, this tool has also provided the function that allows centralised performance data management. To sum up from the points above, the SPPM is an innovative and advanced strategic approach that can provide valuable support for the shipyard production performance management.This research has been motivated by a demand from industry for an efficient decision support tool for shipyards to select and implement the right performance improvement strategies that fit the nature of their own business.

The feasibility of implementing a congestion charge on the Halifax Peninsula: filling the 'Missing Link' of implementation

Congestion charges pose a policy dilemma due to the balance that must be made between the management of a quasi public good along with the correction of negative externalities against the needs of economic, demographic, and urban growth along with citizen acceptance. The literature provides detailed rationales for congestion charges but minimal consideration on how to implement such charges once the decision to proceed has been made. The purpose of this article is to expose some of the technical and administrative issues that come with enacting and implementing congestion charges. The Halifax Peninsula is used as a case study to illuminate the topic. Drawing on this case, we spell out eleven ex ante implementation criteria that can be used to assess implementation considerations in any given congestion charge context. In so doing, we argue that context-specific factors must also be recognized and accommodated by policy and decision makers if congestion charge policy is to present a feasible, and palatable, choice
