Cycling is widely regarded as a healthy and sustainable transport option in urban environments. However, there is an emergent need to understand how cycling in countries like Brazil, can be encouraged and supported, particularly among different sections of the population. This study investigates social-psychological antecedents of cycling within the Brazilian context using a large-scale dataset to verify the appropriateness of a model based on the extended Theory of Planned Behaviour (e-TPB). In-person interviews were conducted with people living in three large Brazilian cities – Brasília ( n =1107), Florianópolis ( n =1084), and Porto Alegre ( n =1105) using a questionnaire including nine items from the e-TPB to measure attitudes, social norms, perceived behavioural control, intention, cycling behaviour, and habit. Multigroup analysis verified the model fit and invariance in structural weights by gender. Age and gender were revealed to be the only sociodemographic variables with significant influence on the components’ mean scores, with gender exhibiting the strongest influence. We concluded that the e-TPB allows us to explain cycling behaviour among this sample of the Brazilian population and that it is particularly sensitive to (a) other people's influence (b) personal habit (c) perceived behavioural control (d) belief in the ability to change one’s behaviour. Women were less likely to cycle and were less likely to be influenced by social-psychological components that could encourage this type of activity. Thus, we conclude that understanding the social and cognitive determinants of cycling can help to design more targeted policies for different sections of society.

Toraja is a popular tourist destination in the sacred highlands of South Sulawesi, Indonesia. It has been widely known for its unique traditional culture. The combination of nature, agriculture, and culture is landscape beauty as area potential tourism. However, the management of tourism objects and attractions has not given much attention to the quality of the landscape aesthetic. This paper shows the results of scenic beauty assessment of culture-based landscape in the North Toraja Regency. Field survey and analysis using Scenic Beauty Estimation (SBE) were used as the method of this research. The results showed that the SBE score represented by 40 landscape pictures ranged from -42 to 234. The landscape that achieved the highest SBE score of 234 was Lolai To'tombi, while the landscape with the lowest SBE score of -42 was Limbong Agrotourism. The preferred landscape has a unique characteristic, in order, having a harmonious blend of hardscape elements and vegetation, and the presence of green open space or blue sky in the landscape. Managers of tourism objects need to consider the character of the landscape in developing tourism objects and attractions to improve the quality of landscape beauty.

He directed the preliminary design of FFG-7 and later served as project technical director. Subsequent tours included duty as project manager nuclear cruiser acquisitions and assistant to the deputy under secretary of defense (acquisition). Upon retirement he joined Sun Shipbuilding and Dry dock Company serving as V. P. program management and V. P. engineering. His education includes a B. S. from the U.S. Naval Academy and an M. S. in naval architecture and marine engineering and a naval engineer's degree from MIT in 1958.

In recent years, the expanding use of electromagnetic systems in warships has created significant problems. Mutually antagonistic systems degrade intended performance and serious safety problems have been created. The environmental effects produced by these systems must be considered in the mainstream of the warship design process. Systems engineering considerations using specific examples will show the potential impact on warship design considerations not normally considered. In addition, electromagnetic engineering considerations are proposed for impact on specific ship specification sections.

An introduction to a rational development of transverse stability criteria for surface ships is presented in this paper. The development is based on a probabilistic analysis of the uncertainties associated with the design parameters involved in determining the transverse stability. Reliability methods are used for assessing and determining transverse stability of ships. These reliability methods address the uncertainties associated with the basic design variables that are involved in stability assessment and design. The sources of uncertainty in stability variables are presented, uncertainties associated with these basic random variables are summarized, different reliability assessment methods are described, a case study that shows the computation procedure using some of these methods is discussed for illustration purposes, and finally, conclusions and recommendations for further work in this area are presented.

A turning point occurred in naval engineering in 1972 when the U.S. N avy chose to use marine gas turbines for the propulsion of its new SPRUANCE and PERRY Class ships. This paper reviews the more than twenty years of experience with turbine technology and its design integration into combat ships needed to make that decision. It is concluded that the availability of a good second generation aircraft derivative engine with proven reliability and a strong commercial base, i.e., the LM-2500, was as important to the decision as was the predicted improved ship effectiveness and cost benefits. This paper discusses improvements that can be made to the twin engine, single gear, single propeller shaft system. Focusing only on this mechanical transmission concept, it addresses the impact of possible improvements to the engine, gear, and shafting. In particular, the paper discusses current LM-2500 related R&D efforts to: (a) obtain improved part-power fuel rates, (b) integrate with a reversing reduction gear, and (c) add on a waste heat recovery steam cycle. Looking ahead to the year 2000, this paper suggests that a successor to the ubiquitous LM-2500 will appear in the 15 MW power range to provide the next step in the evolution of the twin engine package. This new naval engine will most likely be based on an aircraft core that exists at present, such that it will have demonstrated its reliability and commercial potential through many hours of testing prior to its mid-1990 marine conversion. This new engine is expected to offer improved air flow, an excellent fuel rate (approaching a flat 0.30 LB/HP-HR), and effective maintenance monitoring, all at some expense in size, weight, and cost. The year 2000 engine will burn a liquid hydrocarbon fuel similar to JP-5 because of its aircraft origins. Combined with advances in gear and shafting technology, the full twin engine propulsion system of the year 2000 should be markedly lighter, smaller, and more efficient than today's units.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.
