The purpose of this paper is to review the historic development of the requirements for sub-floor (also known as “basementless space” or “crawl space”) moisture management in the USA, UK and New Zealand (NZ) from 1600s to 1969.

The review of 171 documents, including legislation, research papers, books and magazines, identified three time periods where the focus differed: 1849, removal of impure air; 1850–1929, the use of ground cover and thorough ventilation; and 1930–1969, the development of standards.

Published moisture management guidance has been found from 1683, but until the 1920s, it was based on the provision of “adequate” ventilation and, in the UK, the use of impermeable ground cover. Specific ventilation area calculations have been available from 1898 in the UK, 1922 in the USA and 1924 in NZ. These are based on the area of ventilation per unit floor area, area of ventilation per unit length of perimeter wall, or a combination of both. However, it was not until 1937 in the USA, 1944 in NZ and after the period covered by this paper in the UK, that numerical values were enforced in codes. Vents requirements started at 1 in. of vent per square foot of floor area (0.7 per cent but first published in the USA with a misplaced decimal point as 7 per cent). The average vent area was 0.69 per cent in USA for 19 cases, 0.54 per cent in NZ for 7 cases and 0.13 per cent in UK for 3 cases. The lower UK vent area requirements were probably due to the use of ground covers such as asphalt or concrete in 1854, compared with in 1908 in NZ and in 1947 in USA. The use of roll ground cover (e.g. plastic film) was first promoted in 1949 in USA and 1960 in NZ.

Common themes found in the evolution of sub-floor moisture management include a lack of documented research until the 1940s, a lack of climate or site-based requirements and different paths to code requirements in the three countries. Unlike many building code requirements, a lack of sub-floor moisture management seldom leads to catastrophic failure and consequent political pressure for immediate change. From the first published use of performance-based “adequate” ventilation to the first numerical or “deemed to satisfy” solutions, it took 240 years. The lessons from this process may provide guidance on improving modern building codes.

This is the first time such an evaluation has been undertaken for the three countries.

Holistic renovation of historic and heritage buildings involving different stakeholders has the potential to reduce environmental impact. Climate change concerns are emphasizing environmental issues of cultural built heritage leading to new policies, guidelines and methods dealing with the challenge on how to lessen the environmental impact of built heritage without damaging its cultural significance. The purpose of this paper is to review existing international and New Zealand holistic guidelines for renovation of historic and heritage buildings.

A systematic review is used to identify international projects, methods and criteria within the holistic approach. Secondly, the New Zealand context is explored and compared with best international practices.

For instance, in New Zealand one increasingly important issue is the many vacant heritage and historic buildings in provincial town centres that need action to deal with building code seismic changes. Upgrades and adaptive reuse are opportunities to make them more sustainable and climate change resilient. However, the lack of national holistic guidelines regarding the challenge of reducing environmental impact whilst keeping the heritage values is a critical gap which urgently needs to be resolved. The need is further increased within the context of the recently passed Zero Carbon Act 2019, which aims for national zero carbon emissions by 2050.

These shared responsibilities for conserving historic and heritage buildings to maintain life in provincial towns on one hand, and the need to reduce greenhouse gas (GHG) emissions on the other, have the potential to contribute to a sustainable development of cities and communities.

New Zealand building code may be serving its purpose to an extent, there is still a need to develop a framework to improve the use and application of building code for better building performance and services. This study aims to validate the identified parameters in the developed framework to improve building code practice in New Zealand.

Subject matter experts interview was conducted with key stakeholders that use building code, standards and other associated compliance documents.

The findings from this study establish the importance of improving the building code, and the efficacy of validated framework helps to identify the areas with the most pressing needs within the building regulatory system. All the subject matter experts unanimously agreed on educating and training the building code users. Besides, the validated framework will enable the policy decision-makers in the building regulatory system to promote the use of building code and the utilisation of its potentials in reducing disaster while increasing the built environment resilience. The study concludes that the designed framework will create more robust strategy implementations to enhance innovative solutions embedded in performance-based building code.

This study originality centres on the practical application of an evidence-based framework for performance-based building code, standards and other related compliance documents.

A substantial number of production assets in the offshore oil and gas industry are facing operation beyond their anticipated design life, thus necessitating a service life extension program in the future. Selection of the most suitable strategy among a wide range of potential options to extend the lifetime of equipment (e.g. re-using, reconditioning, remanufacturing, refurbishing and adding on safety/process control measures) remains a challenging task that involves several technical, economic and organizational complexities. In order to tackle this challenge, it is crucial to develop analytical tools and methods capable of evaluating and prioritizing end-of-life strategies with respect to their associated costs and quantifiable benefits. The paper aims to discuss these issues.

This paper presents a life-cycle cost-benefit analysis approach to identify the most suitable life extension strategy for ageing offshore assets by taking into account all the capital, installation, operational, maintenance and risk expenditures during the extended phase of operation. The potential of the proposed methodology is demonstrated through a case study involving a three-phase separator vessel which was constructed in the mid-1970s.

The results from the application case indicate that the capital expenditure (CapEx) accounts for the largest portion of life cycle cost for the replacement strategy, while risk expenditure (RiskEx) is the major contributor to costs associated with life extension. A sensitivity analysis is also conducted to identify factors having the greatest impact on the optimum life extension solution, including oil price, production rate and money interest rate.

In the past, the decisions about life extension or replacement of in-service equipment were often made in a qualitative way based on experience and judgment of engineers and inspectors. This study presents a “quantitative” framework to evaluate and compare the costs, benefits and risks associated with life extension strategies and subsequently to select the best strategy based on benefit/cost ratios.

To the best of authors’ knowledge, no studies before have applied life cycle assessment and cost-benefit analysis methods to prioritize the potential life extension strategies in the oil and gas industry sector. The proposed approach not only assists decision makers in selecting the most suitable life extension strategy but also helps duty holders reduce the costs corresponding to life extension execution.

Butt can be placed within the framework of what George Boyce (1995, pp. 18–19) terms colonial patriotism. Butt's analyses of Ireland's economy and development during the next years brought together the several strands that marked out an Ireland of citizens, an Ireland of sort which has emerged at the turn of the present millennium. What were the influences on Butt and what is his place in the development of political economy? His position is best characterised as eclectic and distinct from the other early holders of the Whately Chair. Drawing upon but not endorsing classical political economy, Adam Smith, Longfield, Jean-Baptiste Say and others, Butt defies pigeonholing. His economic analysis emerged slowly, and initially, there was little hint that he would expand on Longfield's position which essentially was a theory of profit (McGovern, 2000, p. 5). However, Butt moved beyond Longfield's analysis and whereas the latter remained in the classical tradition on free trade, he did not. He expanded Longfield's approach that crucial to the determination of the price of goods was the importance of applying a unit of whatever resource to its marginal use, concluding that the factors of production were remunerated in relation to the utility they created in their least efficient, marginal employment (Boylan & Foley, 2003, Vol. 2, p. 10). His importance, it has been observed, was in drawing attention to the potential resource mobilisation and distribution aspects of protection and in assessing the benefits and weaknesses of protection in relation to the complexity of specific circumstances (Boylan and Foley, 2003, Vol. 3, p. 5). Butt's Whatley lectures have received most attention although it will be suggested that certain of his other writings were as important or even more significant as indicative of his ideas on political economy. In his first Whatley lecture (Butt, 1837a), appropriating the title ‘Introduction’, Butt outlined somewhat verbosely the scope of what he intended to address and adopted the high ground about the purpose of political economy. He declared it was ‘to teach certain truths connected with the social condition of man – it attempts to explain the nature of the causes by which is brought about that singular machinery of society by which Providence has set man to supply each other's wants, and thus receive and confer a mutual benefit’ (1837a, p. 23). Butt addressed the question of production and the creation of ‘utility’. Employing the illustration of cotton stockings, Butt demonstrated the complex interchange required to produce even the most mundane of articles (1837a, pp. 25–26). ‘When you purchase your pair of cotton stockings’, he noted, ‘you are positively commanding for your own personal comfort and accommodation, not only the services of thousands of your cotemporary fellow creatures, but the accumulated results of the labours of generations that have long since passed away’ (1837a, p. 28). Thus, he maintained, political economy ‘teaches the laws which regulate the production, distribution and consumption of wealth’ (1837a, p. 30).

The foreign intervention in Libya in 2011, legitimized by the Security Council Resolution 1973, whose veto is a privilege of solely five most powerful countries (at least from post-1945 war standpoint), not only reveals that same practice of the past still valid in international affairs today but also results in overthrowing Gaddafi regime, and most importantly in destabilizing a once stable nation, which can now be seen as a failing state.

Seligman is an important and ironically somewhat neglected figure today in the history of American economic thought. However, an examination of his scholarly achievements reveals that he had a considerable impact on the development of professional economics in America and could count the most influential economists in Europe as personal friends and collaborators (Moss, 2003; Rutherford, 2004; Mehrotra, 2005). Asso and Fiorito (2006), in their introduction to Seligman's autobiography (1929) argue that ‘his personal influence as an academic economist, as a teacher and as a central figure in the dissemination of economic knowledge was second to none and perhaps more meaningful than any single work he wrote’ (p. 1). They also record (quoting his student, Alvin Johnson) that ‘with Seligman…American economics began to acquire a distinctive professional reputation, some very high scholarly standards and a sort of “moral magnificence”’ (p. 2). What this means is that through Seligman's work and guidance economics came to encompass a moral dimension that fed through into social policies, many of which were adopted by American legislatures. The major influences on his method included the German Historical School and a number of heterodox Continental writers that informed Seligman's in great Whig interpretation of the development of economics. He also engaged critically with the more abstract methods of contemporary economic analysis of the early twentieth century.

The International Electronic Components Show in Paris in November, 1983, provided the occasion for a very successful meeting of ISHM‐France which attracted 170 attendees. The following presentations were given:

The purpose of this paper is to examine the motives and emotions of Western tourists visiting Tuol Sleng Genocide Prison Museum in Phnom Penh, Cambodia and further contribute to a deeper understanding of the dark tourism consumption.

Data were collected from popular travel blog sites. This study employs various qualitative and quantitative methods, such as netnography, semantic network analysis and critical content analysis in order to gain a deeper insight into the visitors’ emotions and motivations.

This study reveals that people visit Tuol Sleng Genocide Museum mainly for “remembrance”, “worth visiting”, “learning and understanding”, “paying respect” and a “must visit” attraction. Emotions revealed in this study were “shocking“, “sadness“, “horror” and “depressive”.

This paper is limited to the analyses of travel blogs sites. Further research could include interviews with Western visitors, and professionals managing the site.

To the best of the knowledge, this is the first study to examine the emotions of visitors in Tuol Sleng Genocide Museum.
