Book review: As If: Idealization and Ideals by Kwame Anthony Appiah
No full textThis is the author accepted manuscript. The final version is available from OUP via the DOI in this recordBook review of As If: Idealization and Ideals by Kwame Anthony Appiah. Cambridge, MA: Harvard University Press, 2017.Kwame Anthony Appiah’s engaging and insightful new book focuses on idealisation. Based on three Carus Lectures delivered at the 2013 Eastern Division Meetings of the American Philosophical Association, the book takes its inspiration from the German philosopher Hans Vaihinger and his The Philosophy of ‘As If’ (1911). Long neglected, Vaihinger’s work has recently been revisited by philosophers of science interested in scientific modelling, most notably Arthur Fine. Vaihinger’s own interests were much broader, however, taking in metaphysics, mathematics, ethics, law, theology and economics. Appiah’s range is equally impressive and his discussion applies Vaihinger’s ideas across a wide range of areas, including philosophy of mind, economics, moral and political philosophy. In doing so, it offers a striking and extremely valuable insight into the pervasive role of idealisation in human thought. [...

No full textAnalysis of the Parametric Instability of the STC Combined Wind and Wave Energy Concept
No full textResonant motions of a combined wind and wave concept (STC) in waves may induce significant loads in the structural components (such as wind turbine blades, nacelle or the interface between the spar and the torus). One type of resonant motions is related to the so-called Mathieu instability. For the STC under the survival mode where the torus is locked to the spar at the mean water level (MWL mode), the large heave motion in severe waves induces a significant change in the buoyancy center and therefore leads to a periodic change in the restoring term for the pitch motion. When the wave period reaches the half of the natural period, the Mathieu instability (a dynamic instability in pitch for this case) occurs and leads to significant pitch motions.The purpose of this study is to numerically predict such unstable motions for regular and irregular wave conditions and to compare the results with the experimental observations. First, a literature study on Mathieu instability is carried out to understand the mechanism behind this phenomenon. Then the results of the STC concept from the experiments carried out by Dr. Ling Wan are investigated in order to study the developments of the Mathieu unstable pitch motions and the corresponding wave conditions in which they occur. Finally, a numerical model of Mathieu instability for analysis of the STC pitch motions is established to get insight into the phenomenon.The numerical model is compared with the experimental results of Dr. Ling Wan. A sensitivity study using the numerical model is then carried out to investigate the conditions where the Mathieu instability may occur

What makes mortgage finance markets work? An inquiry into residential mortgage finance development in developing economies
No full textHousing costs typically constitute more than the annual income of potential homeowners both in
developed and developing countries. The capital-intensive nature of housing investments, therefore,
make some form of consumption smoothening necessary for homeownership to become affordable
to many people. Mortgage finance development therefore contributes to economic growth and
development. Despite its relevance, well-functioning mortgage finance systems have hardly emerged
or are underdeveloped in most developing economies. The underdevelopment of mortgage markets
is a characteristic that is not limited only to developing countries but also to some rich countries.
This field has therefore excited academic interest, but gaps remain in the comparative analysis of the
organisation, structure and performance of mortgage markets in developing economies. This research
attempts to fill some of those gaps.
Using a multi-method research approach, implemented in three papers, this thesis investigates the
extent to which markets enable mortgage finance and the reasons for wide variations in mortgage
finance. Across 116 developing economies, we found that mortgage finance markets are more likely
to deepen in highly urbanised countries. These countries are characterised by higher income levels
(middle-income threshold and upwards); macroeconomic stability, large economically active
population who have better access to the financial system and long-term lenders. These are lenders
who can allocate mortgage credit relatively efficiently through public credit registers and whose
rights are well protected by stronger institutional and regulatory frameworks. Other factors emerging
from the case studies include having cultures that favour mortgage (debt) financing; land
administration efficiencies; and efficient urban management and governance systems that foster the
adequate supply of quality affordable housing in well-planned locations that benefit from the
effective enforcement of development controls. Further, improving financial literacy levels and
financial innovation may contribute to mortgage finance development.
The findings also indicate that stronger creditor property rights are associated with economies that
are characterized by political stability, higher corruption control, effective governments, higher
income levels, and judicial independence. It is argued here that these favourable factors are also not
necessarily products of legal heritage, culture and geography as is assumed by existing theories of
financial development. The political economies and political ideologies of developing economies
play key roles in determining the quality of their mortgage institutional settings and the existence of
these favourable conditions with ramifications for mortgage finance development.
The results have policy implications, some of which are briefly outlined here:
1. Financial inclusion (access) is leading indicator of financial and mortgage deepening;
2. There is a need for macroeconomic strengthening to improve affordability and demand for
mortgage finance; 3. Economic and financial liberalisation promote mortgage deepening and financial
development. The achievement of this outcome requires the development of economic
institutions and infrastructure such as credit information sharing systems and appropriate legal
systems. Poor legal fundamentals, in particular, the inability to create and enforce a mortgage
lien in a reasonably efficient and cost-effective manner and high credit information asymmetry
leads to increased risk of mortgage lending, higher transactions costs and markets that are both
smaller and shallower regarding income strata served and the total size of investments;
4. Financial literacy and mortgage education is likely to make a significant contribution. There
is, therefore, a need to instil mortgage financing as a culture deliberately;
5. Housing and urban planning policies to supply quality affordable housing in well-planned
communities mostly those around central business districts are also vital. Mortgage financing
could help in improving urban planning and the enforcement of development controls;
6. The digitisation of land title registers coupled with efficient access by creditors at lower cost
must be prioritised if land registration is to have a significant effect on mortgage finance
development;
7. Mortgage finance and finance general in developing countries benefits from a demographic
dividend. Governments in developing countries (especially African countries) must take
advantage of their large, youthful, and economically active population to put in the right
policies and systems to develop mortgage finance
The dynamics of social media and value co-creation
No full textSocial media is considered trustworthy by consumers, and this has resulted in a strong consumer focus on social media to acquire information related to products and services. There are various benefits offered by social media, but security is a major concern as viruses and other threats can affect a huge number of users of social media. These platforms are not well governed. Indeed, they are highly decentralized and could easily be accessed, and this presents a high risk of illegal activity. Businesses continue to reap the benefits of incorporating social media into their strategies. There has been a shift in focus from conventional media to online and digital media in the form of social networking sites, wikis, and blogs. This has given rise to viral marketing as a means of effective communication and sharing information. The current chapter aims to explore the relationship between social media and value co-creation

Assertion and Conditionals
No full textThis book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses.</jats:p
