Abstract Dried fish has become one of the favourite food for Indonesian. The drying technology has been passed down through generations especially in the coastal communities due to its simplicity. Despite the long history of dried fish in Indonesia, some problems need to be addressed. Maintaining the quality for both domestic and global markets in an integrated and sustainable manner is still standing as the major problem. Formalin residue had been found in some dried fish products in several areas in Indonesia. This safety matter is also drawn both researcher’s and policy maker’s attention. Several possible solutions are offered to iron out the issues. The development of new technology which easy to adopt and low cost is needed. A combination drying machine can be an alternative to solve the problems. The machine is designed to be able to operate using both electrical and solar sources. The machine can yield a good quality product which can be used throughout the year.

The Great Leap Forward

In 1949, at the end of a long period of wars, one of the biggest challenges facing leaders of the new People's Republic of China was how much they did not know. The government of one of the world's largest nations was committed to fundamentally reengineering its society and economy via socialist planning while having almost no reliable statistical data about their own country. This book is the history of efforts to resolve this “crisis in counting.” The book explores the choices made by political leaders, statisticians, academics, statistical workers, and even literary figures in attempts to know the nation through numbers. It shows that early reliance on Soviet-inspired methods of exhaustive enumeration became increasingly untenable in China by the mid-1950s. Unprecedented and unexpected exchanges with Indian statisticians followed, as the Chinese sought to learn about the then-exciting new technology of random sampling. These developments were overtaken by the tumult of the Great Leap Forward (1958–1961), when probabilistic and exhaustive methods were rejected and statistics was refashioned into an ethnographic enterprise. By acknowledging Soviet and Indian influences, the book not only revises existing models of Cold War science but also globalizes wider developments in the history of statistics and data. Anchored in debates about statistics and its relationship to state building, the book offers fresh perspectives on China's transition to socialism.

One influence of war has repeatedly asserted itself in the past—an effect on the costs of production and on the competitive position of the industries and firms of victorious or neutral nations. This subject needs more study, but certain facts suggest a hypothesis, of three parts. First: war expands some industries or concerns, increases their efficiency, enables them to operate, at the end of the struggle, on a comparatively low-cost basis, intensifies their competitive advantages, and improves their position in relation to foreign competitors. Second: war—for the duration—bolsters up some high-cost units by enabling them to sell at a profit all they can produce. The end of the war places such high-cost units at a disadvantage in the process of absorbing the shocks of the transition to a peacetime economy. Third: the history of postwar periods usually exhibits a sharp contest between such low-cost and high-cost enterprises. While “low cost” and “high cost” may refer to the relative positions of units within the same country, in most of this discussion, the terms will be applied to the producers of one country (either victor or neutral) to mean that their costs are low or high in comparison with those of their foreign competitors.

It’s easy to get swept up in the excitement of new technology that appears to have potential to transform everything, including education. But, as Rafael Heller explains, educators have a long history of being seduced by technologies that never really lived up to their promise. That’s no reason to ignore technology’s potential, but plenty of reason to be realistic about what it can achieve.

Abstract In this essay, I offer a brief history of manuscript cataloguing and some observations on the innovations this practice introduced especially in the digital form. This history reveals that as the cataloguing of medieval manuscripts developed over time, so did the research needs it served. What was often considered traditional cataloguing practices had to be mediated to accommodate new scholarly advance, posing interesting questions, for example, on what new technologies can bring to this discussion. In the digital age, in particular, how do digital catalogues interact with their analogue counterparts? What skills and training are required of scholars interacting with this new technology? To this end, I will consider the importance of the digital environment to enable a more flexible approach to cataloguing. I will also discuss new insights into digital projects, especially the experience accrued by the The Production and Use of English Manuscripts 1060 to 1220 Project, and then propose that in the future cataloguing should be adaptable and shareable, and make full use of the different approaches to manuscripts generated by collaboration between scholars and librarians or the work of postgraduate students and early career researchers.

Sign language datasets are essential to developing many sign language technologies. In particular, datasets are required for training artificial intelligence (AI) and machine learning (ML) systems. Though the idea of using AI/ML for sign languages is not new, technology has now advanced to a point where developing such sign language technologies is becoming increasingly tractable. This critical juncture provides an opportunity to be thoughtful about an array of Fairness, Accountability, Transparency, and Ethics (FATE) considerations. Sign language datasets typically contain recordings of people signing, which is highly personal. The rights and responsibilities of the parties involved in data collection and storage are also complex and involve individual data contributors, data collectors or owners, and data users who may interact through a variety of exchange and access mechanisms. Deaf community members (and signers, more generally) are also central stakeholders in any end applications of sign language data. The centrality of sign language to deaf culture identity, coupled with a history of oppression, makes usage by technologists particularly sensitive. This piece presents many of these issues that characterize working with sign language AI datasets, based on the authors’ experiences living, working, and studying in this space.

Wave-driven reverse osmosis desalination systems can be a cost-effective option for providing a safe and reliable source of drinking water for large coastal communities. Such systems usually require the stabilization of pulsating pressures for desalination purposes. The key challenge is to convert a fluctuating pressure flow into a constant pressure flow. To address this task, stub-filters, accumulators, and radially elastic-pipes are considered for smoothing the pressure fluctuations in the flow. An analytical model for fluidic capacitance of accumulators and elastic pipes are derived and verified. Commercially available accumulators in combination with essentially rigid (and low cost) piping are found to be a cost-effective solution for this application, and a model for selecting accumulators with the required fluidic-capacitance for the intended system is thus presented.

AbstractThis paper updates the earlier account of the Forties Field detailed in Geological Society Memoir 14 (Wills 1991), and gives a brief description of the Brimmond Field, a small Eocene accumulation overlying Forties (Fig. 1).The Forties Field is located 180 km ENE of Aberdeen. It was discovered in 1970 by well 21/10-1 which encountered 119 m of oil bearing Paleocene sands at a depth of 2131 m sub-sea. A five well appraisal programme confirmed the presence of a major discovery including an extension into Block 22/6 to the southeast. Oil-in-place was estimated to be 4600 MMSTB with recoverable reserves of 1800 MM STB. The field was brought onto production in September 1975. Plateau production of 500 MBOD was reached in 1978, declining from 1981 to 77 MBOD in 1999.In September 1992 a programme of infill drilling commenced, which continues today. The earlier infill targets were identified using 3D seismic acquired in 1988. Acquisition of a further 3D survey in 1996 has allowed the infill drilling programme to continue with new seismic imaging of lithology, fluids and saturation changes. The performance of the 1997 drilling showed that high step-out and new technology wells, including multi-lateral and horizontal wells, did not deliver significantly better targets than drilling in previous years.In line with smaller targets, and in the current oil price environment, low cost technology is being developed through the 1999 drilling programme. Through Tubing Rotary Drilling (TTRD) is currently seen as the most promising way of achieving a step

Primary Data

Purpose: The purpose of the study was to explore the influence of low cost building materials on reduction of housing deficit in Nairobi County, Kenya.Methodology: The study adopted four theories: open innovations theory, the value theory, transformational leadership theory, and institutional theory. Methodologically, the study adopted a descriptive research design, while the population of this study was all the real estate firms registered by Kenya Property Developers Association (KPDA). Census technique was employed to collect data from all 69 real estate firms using questionnaires. Questionnaires were applied to collect primary data, where the researcher trained research assistants to aid the data collection procedure. A pilot-test was conducted as an approach to establishing both the reliability and validity assessments of the questionnaire. Statistical packages for social sciences (SPSS) was used to undertake both descriptive and inferential statistical computations.Results: The findings of the study established that the use of technology enhances the capability and capacity of construction firms to use an array of building materials. The study found that use of modern technology defined skilled labour because most organizations are leveraging technology as a basis of realizing competitive advantage. It also established that real estate firms utilize competent based human resource management firms to hire qualified personnel. In addition, it was evident that personality traits influenced adoption of new technology in the construction of low cost housing, whereas knowledge and attitudes, and skills were significantly attributed to adoption of new technology.Unique contribution to theory, practice and policy: In light of the research findings, the study recommends that organizations should leverage modern technology as a basis of realizing efficiency, effectiveness, and sustainability of projects. The study likewise recommends that organizations should build capacities to enhance labour productivity. In addition, the study recommends that organizations should adopt transformational leadership approaches as a basis of enhancing performance. The study recommends the need to revise the legal framework with a view to ensure that it reflects the changing needs of the project requirements.
