Although the United States is the most powerful nation on earth, the
one area in which this country does not excel is health. And the future
is not bright. Almost a third of our young children are obese,
and many do not exercise. No matter how much information becomes
available about the dangers of a sedentary lifestyle and a diet
heavily dependent on processed foods, we don't change our ways.
Ideally, Americans should be able to translate financial well-being
into habits that lead to longer and better lives, untroubled by expensive
and chronic medical illnesses.
Equivalent units of production for a period can be computed in different ways. In this
chapter, we discuss the weighted-average method. In Appendix 4A, we discuss the FIFO
method. The FIFO method of process costing is a method in which equivalent units and
unit costs relate only to work done during the current period. In contrast, the weighted-
average method blends together units and costs from the current period with units and
costs from the prior period. In the...
Further, Fich and Shivdasani (2006) find that firms with a majority of their outside
directors serving on three or more boards have lower profitability. Thus busy non-
executive directors may be over-committed and therefore unable to fulfil the role of
effective monitors. In addition, Vafeas (2003) reports that longer outside director
tenure adversely affects firm performance. Hwang and Kim (2009) find that the
existence of substantial social ties between outside directors and top management
diminishes the effectiveness of the monitoring role of non-executive directors. ...
One of the chief benefits enjoyed by Academics is the chance to have exchange and
interchange with both specialists and trainees. During our respective careers, we have
derived, and continue to derive, great rewards from this invaluable communication,
and this was indeed the driving force behind the undertaking of this editorship. The
field of Obstetrics differs substantially from that of plain Gynecology as from other
specialties as well, since the wishes and expectations of the pregnant woman are very
specific and unusually exacting.
THE ROLE OF LEARNING IN ACHIEVING PRODUCTIVITY IN NON-EDUCATIONAL SETTINGS IN SERVICE ORGANIZATION My empirical analysis thus has two components. In Section 1.5, I look for evidence
that effectiveness sorting is more complete in high-choice than in low-choice markets, as the
simulations above suggest it should be if parental valuations attach substantial weight to
SEEING THE INVISIBLE: A TEST OF RATIONAL EXPECTATIONS IN THE VALUATION OF HUMAN CAPITAL Preferred
districts need not have particularly effective schools, however, when peer group enters into
parental valuations, as wealthy families can be stuck in ineffective schools by their
unwillingness to abandon the peer group offered. For parental valuations that place
substantial weight on school effectiveness, this becomes less likely as Tiebout choice
increases parents exit options.
ESSAYS ON THE RELATIONSHIPS BETWEEN FOREIGN DIRECT IN VESTMENT, INTERNATIONAL TRADE, AND EXCHANGE RATE VOLATILITY My analysis of parental choices focuses on the possibility that parents may choose
schools partly on the basis of the peer group offered. Although existing research does not
conclusively establish the causal contribution of peer group characteristics to student
outcomes (see, e.g., Coleman et al.
Experts agree that attempts to prevent childhood obesity and its health consequences, such as
type 2 diabetes, must shift the focus from treating overweight children to addressing health
disparities among children of varying socio-economic status. and mitigating the social and
environmental factors that contribute to the declining health of children overall. The nation’s
health care costs for treating diabetes are $92 billion.
The evidence base that examines the cognitive implications of playing is complex and not
entirely consistent. However, there is substantial evidence overall to suggest that play is a
natural way of building cognitive processes, assisting learning and can even help with more
complex mental health issues. However, caution should be exercised when linking play to
cognitive functioning, as this can lead to the ‘instrumentalising’ of play (Lester and Russell
There are several improvements for bipartite network ﬂows . However they require the network to be unbalanced in order to substantially speed up the algorithms, i.e. either |U | |V | or |U | |V |, which is not the case in our context. The complexity of ﬁnding an optimal (minimum or maximum weight) matching might be reduced if the cost label is also a metric on the node set of the underlying graph. For example if the nodes of the graph are points in the plane and the cost label is the L1 (manhattan), L2 (Euclidean) or L∞ metric...
Analyzing monthly return data on more than 2500 unique U.S. equity
funds over the period 1984–2003, we show that the average return gap is
close to zero. In particular, the equally weighted return gap for all mutual
funds in our sample equals 1.1 basis points per month, while the value-
weighted return gap equals −1.0 basis points per month. These results
indicate that the magnitude of unobserved actions is relatively small in the
aggregate. Thus, fund managers’ trades in the aggregate create sufﬁcient
value to offset trading costs and other hidden costs of fund management.
Using the broadest possible definition, a lipid (Greek
) may be defined as a compound
of low or intermediate molecular weight (5000), a substantial proportion of which is made up of
hydrocarbons. Included are diverse compounds such as fatty acids; soaps; detergents; steroids;
mono-, di-, and triacylglycerols; and more complex compounds such as phospholipids, sphingolipids,
glycolipids, and lipopolysaccharides.
Statistical Prediction Models
Bayes' theorem, as presented above, deals with a clinical prediction problem that is unrealistically simple relative to most problems a clinician faces. Prediction models, based on multivariable statistical models, can handle much more complex problems and substantially enhance predictive accuracy for specific situations. Their particular advantage is the ability to take into account many overlapping pieces of information and assign a relative weight to each based on its unique contribution to the prediction in question.

Literature reports comparing Ethiopian Boran with other indigenous Ethiopian cattle breeds
indicate better growth performance for Ethiopian Boran (Table 2). Additionally, through
improvement in management and selection, performance of Boran has been substantially
improved. For example, the improved Boran is heavier at birth averaging 30 kg (DAGRIS
2006) and at Abernossa ranch in Ethiopia the weaning weight was estimated at 158
kg (Banjaw and Haile-Mariam 1994). This variation indicates the potential that can be
exploited by within breed selection and improvement in management. ...
Each basic food group5 is the major contributor of at least
one nutrient while making substantial contributions of
many other nutrients. Because each food group provides
a wide array of nutrients in substantial amounts, it is
important to include all food groups in the daily diet.
Both illustrative eating patterns include a variety of nutrien
dense foods within the major food groups.
The aim of this paper is to investigate the use of sample reweighting, in a behavioural tax
microsimulation model, to examine the implications for government taxes and expenditure of
population ageing in Australia. Tax microsimulation models are based on large-scale cross-sectional
surveys containing substantial information about the characteristics of individuals and house-
The population exposure without PM10 fraction attributable to road traffic is shown in Figure 6.
Compared to total PM10, the frequency distribution changes considerably. Most people would live in
areas with PM10 values less than 20 µg/m3. In France and Switzerland, less than 3% of the population
would live in areas with PM10 greater than 20 µg/m3. In Austria, this portion is higher due to an
increased non-traffic caused regional PM10 background.
The development of the Cambodian rubber industry during the past two years has
been noticeably positive due to the substantial and continuous rise in prices of
natural rubber. In 2007 and 2008, total harvested areas and natural rubber
production increased by 30 per cent and 12 per cent, respectively. Additionally, the
outcome of the divestment by the Government of Cambodia of its state-run rubber
plantations has also been impressive. As of early 2009, the seven state-run
plantations had already been privatized, discharging more weight of the public sector
onto the private sector.
