Prent ice Institute Publicat ion
Summer 2015 is far from a time of fun in
the sun for us in the Prentice Institute. It is
full steam ahead with our many research
and outreach endeavours. Many of us
associated with the Prentice Institute are
giving research papers at various
conferences. And all are busy doing research
and writing up our research for publication.
The reach and recognition of the
Prentice Institute grows each year locally,
nationally and internationally. Our research
is always peer-reviewed and academic. This
gives the research we do a special credibility
and helps build our reputation across the
world. You will get a sense of the breadth
and amount of research we are doing from
checking the URL below. This will take you
to a summary report of our research over
only a two year period. It will be apparent
why the reach and reputation of the
Prentice Institute is growing by leaps and
bounds.
Wishing all our followers and supporters an
enjoyable summer.
~Susan A. McDaniel
Who is the ‘duck’ in
gumboots? Well, let me
introduce this duck, which
is actually a gull. What
everyone in the Prentice
Institute refers to as a
duck, seems to make an
appearance every time I
appear in any news story
that includes a photo. This
is one photogenic ‘duck’ so
we thought maybe she/he
has become our mascot.
She/he may need a name.
Suggestions welcome.
The Prentice Institute has published a summary report
showcasing the outstanding research done by our many
afiliates at the University of Lethbridge, across Canada
and over-seas. Covering the academic years of 2013-
2015, this publication highlights the numerous ways our
affiliates contribute to their diverse fields of study.
Included is how active many of them are in outreach to
their communities and society at large. We are proud to

Prentice Institute Post Doc Dr. Jing Shen says goodbye
Dr. Andrew Patterson joins us from the
University of British Columbia where he
completed his Ph.D. in Sociology. His
research compares the impact of political
regimes on population health. He finds a surprisingly strong relationship
between democratic governance and population health. As part of his post-doctoral
research, he intends to compare more regime types, further
exploring the relationship between democracy, economic prosperity and
health, attempting to discern why neither systems of accountability for
leaders’ decisions nor social inequalities act as mediators. He is very keen
to analyse causes and explanations of the relationship of governance to
population health, relying on an ecological
perspective.
We are sad to see Jing leave our Institute early. She completes her journey here on
April 30th and will return to her husband in Toronto shortly thereafter.
We wish you well Jing, with all your future endeavours!
Dr. Daniel Dutton is currently a Research Associate at The School of
Public Policy, University of Calgary. His training is in population health and
economics and he has a special interest in how policy can change
population-level health outcomes. In the past he worked for the Ontario
Ministry of Finance before moving to Alberta for his Ph.D.
On a side note, in a funny email exchange, Daniel wanted me to mention that
he is very disorganized . I don’t believe it.

A people-to-people initiative to rebuild school
libraries in disaster-affected communities
ReadWorld Foundation has sent over 30 boxes of
donated books to Tacloban City, Philippines to help
rebuild libraries in public schools affected by super
typhoon Haiyan. This was made possible by the
generosity of the Lethbridge community- schools,
students, teachers, parents, colleagues, friends,
residents, and West Lethbridge Lions Club.
Update:
It takes more than 1 box to reconstruct libraries damaged by the strongest typhoon ever recorded. The Lethbridge community has
continued donate books and we need to ship them. We are looking for sponsors to help us send these books to the Philippines.
Shipping cost of 1 standard box (18 x 18 x 33) is $90. Please contact [email protected] if you wish to become a

Our New Postdoctoral Fellow
The highlight of 2014 was the 5-year celebration of
the Prentice Institute for Global Population and
Economy. We hosted a delightful celebratory party in
April, just as the spring academic term was ending.
Photos of the event are included in this issue. We also
produced a 5-year report, which if you have not seen,
is available on our website: www.uleth.ca/
prenticeinstitute/news/prentice-institute-five-year-report
It has been a busy five years indeed, and we are only
beginning. With the many successes we have had and
the recognition locally, regionally, nationally and
internationally we have received, we anticipate a very bright future for the Prentice
Institute.
The awarding of scholarship funds by the Society of Edmonton Demographers to
the Prentice Institute for graduate studies in Population and Demography is a
welcome indication of our growing prominence in Population Studies. We were
honoured that Peter Kellett, a Prentice Institute Ph.D. student was officially
awarded the first SED Scholarship in March in Edmonton at the 22nd Kalbach
Conference.
A second banner event of spring 2014 were the successful defenses of two of our
Masters students, Celeste Barnes and Tanya Byrne. Celeste is continuing her
studies, working toward a Ph.D., while Tanya is employed in Calgary.
As usual for active researchers in global population, we present our research and
work with collaborators across Canada and the world. Our travels in 2014 have
taken us to China, Hong Kong, Japan, the United States, Cuba, Mexico, Greece,
Turkey, Iran, and various countries in Africa.
Ye (Oscar) Liu joined the
Prentice Institute for Global
Population and Economy and the
Department of Geography,
University of Lethbridge, as a
Post-doctoral fellow in
November 2013.
He received his B.Sc. and M.Sc.
in China and in 2013, his Ph.D. in
Geography and Resource
Management at the Chinese
University of Hong Kong. His

Five Year Celebrat ion
For five years The Prentice Institute for Global Population and Economy has
been conducting, integrating and stimulating research. Our reach is global with
our nine international Research Affiliates and our 25 University of Lethbridge
Affiliates providing relevant, world-class research. Under the leadership of our
Director, Professor Susan McDaniel,
The Prentice Institute addresses the many
challenges faced in both the Canadian and
global population. The research of the
numerous disciplines represented by the
Institute reaches deeply into the long-term
consequences of our human story, how we
interact in our societies, in our economies,
and in our environments.
These five years have seen much collaboration, many millions in research funding and many of our researchers acknowledged
by their peers as leaders in their various disciplines. Dozens of books, hundreds of research articles and book chapters, dozens
of research reports and projects, and hundreds of conference presentations are all evidence of the success of our various
research teams. Along with active academic research and publication, many of our
Affiliates are engaged in flourishing programs of graduate education. Mentoring the
next generation of Masters and Ph.D.’s is another layer of passing knowledge on. It
doesn’t stop at the door of academia: our Research Affiliates are actively involved
in public outreach and education.
The Prentice Institute has, in the
past five years, been the host of
a lecture series which attract
students, faculty, staff and
members of the community to the
wide variety of subjects. We have been fortunate to come together with a
number of community partners and our interaction with them has been one
of our many highlights. Many of our Affiliates are called on to speak as
experts in their disciplines and can be found as active members of our
community in the news and public speaking forums.
We, at The Prentice Institute for Global Population and Economy, have
had an amazing five years. We live in a complex and global world and
we are excited to be in a position of knowledge and growth, ready to
help meet the challenges of both the present and the future. We look
forward to many more years of association with our Affiliates, the
University, and our community.

“The issue of men’s depression is relatively
hidden, but in another way it’s completely in our
face,” says Kellett. “Men don’t want to talk about
being depressed, but we see and feel the results of
it. When left undiagnosed and untreated, men’s
depression has a huge impact on the overall health
of society. We need to be able to identify men’s
depression and understand all the social contexts
that are tied to it.”
Peter presented his research at the “Aging Across Borders: A Transnational Look at Just Social Policies of Care”
Symposium held in late January 2014 at the University of Southern California.

Peter was awarded the Society of Edmonton Demographers Graduate Student Scholarship. He is the first recipient of
this award so it is a particular honour. Peter’s name will go down in history as he sets precedent for those that follow.
The scholarship was presented to Peter at this years Warren Kalbach Conferenced in Edmonton held in March where he
presented a research paper. Congratulations again, Peter.
Rebecca Deutsch, awarded the competitive Chinook Summer Research Award, began
working at the Prentice Institute in May 2014 for the summer as a research assistant.
Rebecca is currently majoring in Sociology at the University of Lethbridge. Over the past
semester her interests have been increasingly drawn to the way that ideas about bodies are
involved in the conceptualization of individuality and individual rights. Her curiosity lies
in whether or not different approaches to bodies based on gender or race contribute to
increased or decreased levels of violence. She has been exploring the work of Foucault,
Durkheim and Butler. At the Prentice Institute Rebecca is involved in the big Gender
Migration and the Work of Care project, looking at available literature on supply and
demand, income inequality, and various other aspects of care work.
Welcome Rebecca.

Income Inequality and Infant Mortality: A Panel Analysis
of Canadian Provinces (1979-2009)
Adébiyi Germain Boco
Prentice Institute for Global Population & Economy
University of Lethbridge
To examine whether annual changes in
income inequality are associated with
annual changes in infant mortality rates
in the period 1979-2009 in Canadian
provinces.
Research objective Context
Most past studies, looking across countries, states/provinces, and metropolitan areas, has found positive and statistically significant associations
between income inequality and overall mortality (Lynch and Kaplan 1997). However, in recent years more robust statistical methods using larger
and richer data sources have generally pointed to little or no relationship between inequality and mortality (Mayer and Sarin 2005; Spencer 2004).
Ross et al. (2000) conducted a cross-sectional data analysis, using census data and vital statistics, to report that income inequality (median share of
income) in the state or province and metropolitan area is associated with mortality in the United States but not in Canada.
Evidence for a cross-sectional relationship between income and health is strong but is probably biased by substantial confounding (Gunasekara et al
2012). Longitudinal data with repeated income inequality and health measures on the same individuals can be analysed to control completely for
time-invariant confounding, giving a more accurate estimate of the impact of changes in income inequality on health (Gunasekara et al 2014).
Data
The panel data used that contains 10 Canadian provinces for
the years 1979-2009 were obtained from Statistics Canada’s
Canadian Socio-economic Information Management
(CANSIM) database (http://www.statcan.gc.ca/). The data
analyzed were extracted from:

The Prentice-O'Gorman destination appraisal matrix: Iranian case study
No full textPrentice's model was designed to challenge a tendency in contemporary destination marketing to emphasise SSPs (Standardised Selling Points) rather than USPs (Unique (or at least Unusual) Selling Points). This process of standardisation is what the French have termed Banalisation (Prentice 2006b). Prentice's model is a hybrid of traditional destination choice sets models (Crompton 1992; Sirakaya and Woodside 2005) with inputs from the Theory of Reasoned Action (Aizen and Fishbein 1980) and from heuristic choice models (Pham 1998). Prentice further differentiates USPs into UUSPs (Unique Utility Selling Points) UESPs (Unique Experiential Selling Points) USSPs (Unique Symbolic Selling Points). These may be thought of as summarising those aspects of generic imagery and product beliefs that are pertinent to destination differentiation. As specified, Prentice's model is a model of choosing on the part of potential tourists. The question arises as to how destination managers may readily operationalise Prentice's ideas in both their marketing and market based product development or, indeed, simply to think about their destination. Many managers are familiar with SWOT analysis and the operationalisation of Prentice's ideas suggested here builds on this familiarity. The demonstrated means of application is in the form of a matrix combining Prentice's expansion of USPs with a traditional SWOT analysis
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

Type species: Libanobythus milkii Prentice and Poinar In Prentice et al., 1996, monobasic and original designation. Lybanobythus Azevedo, 1999: 2. Lapsus calami. DIAGNOSIS: Head broad; frontal prominence absent; clypeus transverse, clypeal apex short; face lateral to antennal torulus flat; ocelli forming equilateral triangle, near upper tangent of compound eyes; occipital carina present; pronotal collar present, dorsal surface of pronotum nearly 1.5 times as long as mesoscutum; propleura well developed, anteriorly forming a long neck; notauli absent; prosternum large, exposed, diamondshaped; parapsidal lines absent; forewing with open marginal cell; Rs long, much longer than pterostigma, terminating near anterior wing margin, tubular over entire length; R 1 absent; margin of pterostigma within marginal cell convex; 1m-cu present, tubular; Rs+M tubular; Cu basad 1m-cu tubular, distad 1m-cu nebulous; first submarginal cell short; metafemur not flattened; tibial spur formula 1-1-1; pretarsal claws simple. Refer also to Prentice et al. (1996) for additional characters. COMMENTS: Prentice et al. (1996) considered Libanobythus to be sister to all other scolebythid genera based on the presence of a pronotal collar. A cladistic analysis of the family (Carpenter, 1999; Lacau et al., 2000; see below), however, places Libanobythus in a clade with other, principally fossil genera and not as sister to the remaining scolebythid taxa. The pronotal collar of Libanobythus would thus appear to be a secondary reversal and not plesiomorphic. Further details of the cladistic analysis are presented below.Published as part of ENGEL, MICHAEL S. & GRIMALDI, DAVID A., 2007, Cretaceous Scolebythidae and Phylogeny of the Family (Hymenoptera: Chrysidoidea), pp. 1-16 in American Museum Novitates 3568 (1) on page 3, DOI: 10.1206/0003-0082(2007)475[1:CSAPOT]2.0.CO;2, http://zenodo.org/record/473533
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Intern experience at the Texas Transportation Institute: an internship report
No full text"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirements for the degree of Doctor of Engineering."Includes vita (leaf 91)Includes bibliographical references (leaf 57)This report discusses the author's engineering experience at the Texas
Transportation Institute (TTI), Texas A&M University from March 1974 through July 1977. A
report of this experience plus twelve additional hours of academic course work were
substituted for an internship according to requirements established by the College of
Engineering. Although the author could not retroactively establish objectives of the type
associated with a typical internship, the work experience gained could be related to the two
general objectives of an intership: 1. To demonstrate an identifiable contribution to the
organization in which the intern served, and 2. To enable the intern to become aware of the
non-technical aspects of working as an engineer in a non-academic environment. While a member
of the Texas Transportation Institute staff, the author worked on a number of projects in the
areas of highway traffic engineering research and the preparation of continuing education
courses for transportation engineering officials. These assignments were contained within the
Urban Transportation Systems Division of TTI. This report delineates the author's contribution
to four particular projects and discusses the technical as well as non-technical experience
gained from each. Having been exposed to more engineering situations than many of the other
Doctor of Engineering students, the author has already formulated some rather specific
milestones for the future. The Doctor of Engineering program is discussed in conjunction with
its potential for helping the author attain these career goals and objectives. Also, some
thoughts are presented regarding the Doctor of Engineering as a viable alternative to the
Ph.D. in preparing for a career in engineering higher education

The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models
