Is slow what the slow university's about
This is the first of a trio of posts about the Slow University that started life as presentations in a seminar at the Institute for Advanced Studies in Durham University. In it, guest blogger Luke Martell, argues that we shouldn’t fetishise speed at the fast university. This distracts from what’s behind it. And we should ask whether slow is what the slow university’s really about
Finance, Trade and Economic Growth in Thirteen Asian Developing Countries
The main purpose of this study is to empirically assess the impact of financial
deepening, export and investment, on economic growth in thirteen Asian developing
economies. To achieve that end, the bivariate relationship between economic growth
and three macroeconomic variables are tested through these bivariate models, namely:
finance-led, export-led and investment-led. To address the mis-specification problem
inherent in the bivariate studies, a multivariate V AR framework is then utilised to
investigate the long-run relationships among these four variables.
Annual data is used in the analysis covering the period from as early as 1950 to 1996.
The Asian countries selected included Singapore, South Korea, Taiwan, Indonesia,
Malaysia, Thailand, India, the Philippines, Bangladesh, Myanmar, Nepal, Pakistan
and Sri Lanka.
The empirical evidence obtained from this study suggest the following: for the
bivariate studies, results from the finance-led model suggest a bi-directional
relationship between financial deepening and economic growth in South Korea,Taiwan, Bangladesh and Pakistan. For Singapore, Malaysia, Thailand, India and
Myanmar, the evidence supported the "demand following" hypothesis. For the exportled
model, causality results on export-led growth versus growth-led export are mixed
and, in some cases, contradictory. When investment-led model is utilised, there
exhibit one-way Granger causal relationship from investment to growth for South
Korea and Thailand whereas the reverse relationship is shown in Singapore,
Indonesia, Malaysia and Sri Lanka. The feedback relationship is found in the case of
Taiwan, Bangladesh and Pakistan.
Under the multivariate V AR framework, long-run relationships between the
investigated variables are identified in a cointegrating framework, suggesting the
increasing degree of interdependence of these three macroeconomic variables with
economic growth.
Overall result has purported the significance of open economy structure, and outward looking
trade policies in stimulating the economic growth of many developing
economies. Hence, the continuation of open-door economic policies in developing
economies is warranted, and integrating these economies more closely to the
international economies
PRODUCTION OF METAL-BASED IMPLANTS FOR CYRO-FACIAL INJURIES (BLUEPRINTS)
The main objective of this project is to propose a design for a progressive die
for the production of metal based implants for Cyro-facial injuries. The bulk of the
work would be to produce the detailed design drawings or blueprints for each
progressive die components and to suggest the appropriate process plans for the
fabrication of the respective progressive die components. The main concentration is
put in producing the blueprint~ of a progressive die to produce the I-shaped metal
implants. Throughout the first semester, literature reviews are done to gain knowledge
about the working principle of the progressive die and how to design the various die
components needed in the progressive die. Other than that, literature reviews are also
done to gain information about the minimum tolerances, clearances and angular relief
that need to be applied to each die components to ensure the quality of the progressive
die and also the metal implants that will be produced by the progressive die. The basic
step in producing a progressive die is to produce the blank layout. There are many
ways in laying out the scrap strip. However, for this particular project, the blanks are
laid out by adopting the narrow-run, one-pass layout. To optimize the usage of the
material strip while ensuring the quality of the produced implants, minimum bridge
allowances are applied between blanks and between blanks and edges of the strip.
After calculation, the blanking force needed to cut the blank from the strip is
33707.52 N and since the press capacities are usua:lly in tons, a press of more than
3. 789 tons should be chosen to produce this particular metal implants. Other than that,
it is also found that, a total of 63 metal implants can be produced from a 1 m material
strip. On the other hand, in designing the die components, care had been taken in
assigning the correct clearances, angular relief, allowances and tolerances for each
part of the die components. This is to ensure the success of the particular progressive
die. In general, the material selected for the implants are titanium and stainless steel
strips while for the die components, are tool steels, mild steel and cast steel. The main
processes involved for fabricating the die components are Wire EDM and milling
Self-employment in Scotland : trends and its implications for productivity
Self-employment in Scotland has grown significantly in recent years, faster than in many other countries. It has accounted for almost half of overall employment growth over the past decade and over 80% of the growth in the number of businesses in Scotland. Self-employment in Scotland, however, accounts for just over 1 in 10 jobs, lower than in many other countries. This paper outlines recent trends in the growth in self-employment in Scotland, summarises the likely reasons, highlights the characteristics of the self-employed and considers the implications for productivity and economic growth. It notes that productivity levels of self-employed businesses are significantly lower than larger businesses, as are earnings of the self-employed vis-à-vis employees. The fast growth in the number of low productivity, self-employed businesses in Scotland may, in part, explain Scotland’s overall mediocre productivity performance
Slow-roll versus stochastic slow-roll inflation
We consider the classical wave equation with a thermal and
Starobinsky-Vilenkin noise which in a slow-roll and long wave approximation
describes the quantum fluctuations of the graviton-inflaton system in an
expanding metric. We investigate the resulting consistent stochastic
Einstein-Klein-Gordon system in the slow-roll regime. We show in some models
that the slow-roll requirements (of the negligence of )
can be satisfied in the probabilistic sense for the stochastic system with
quantum and thermal noise for arbitrarily large time and an infinite range of
fields. We calculate expectation values of some inflationary variables taking
into account quantum and thermal noise. We show that the mean acceleration
can be negative or positive (depending on
the model) when the random fields take values beyond the classical range of
inflation.Comment: 8 page
