An analysis of trustee role perceptions in the state controlled Washington community college system and the locally controlled Oregon community college system and the relationship between trustee personal characteristics and these role perceptions
This study examined the role perceptions of trustees
in the locally controlled Oregon community college system
and the state controlled Washington community college
system. Authorities in the literature were consulted to
define the "ideal trustee role" and the study determined
which governance system was most effective in fostering
this "ideal trustee role" as measured by trustee role
perceptions.
The relationship between the personal characteristics
of trustees and trustee role perceptions were also
studied. This part of the study showed which trustees in
each system perceived their role as being closest to the
"ideal trustee role."
A questionnaire was developed and disseminated to all
105 Oregon and all 115 Washington community college
trustees. This questionnaire was a series of thirty-six
trustee responsibility statements that related to the
"ideal trustee role." Trustees were asked to respond to
these statements on a Likert scale. Personal
demographics were also gathered on all respondents.
The components of the "ideal trustee role" were
defined as:
(1) Assure that the college fulfills the purpose for
which it was established and evaluate college outcomes.
(2) Select, evaluate, counsel with, and, if
necessary, terminate the chief executive officer.
(3) Interpret community interests to the college and
college interests to the community.
(4) Oversee the acquisition, expenditure and
investment of funds and management of college facilities.
Washington trustees perceived themselves closer to
components 1, 2 and 3 of the "ideal trustee role" than
Oregon trustees and Oregon trustees perceived themselves
closer to role component 4. However, the similarities in
the role perception responses of the two populations were
more noticeable than the differences.
In general, trustees who fell into the following
demographic categories perceived themselves closer to the
"ideal trustee role" than trustees who fell into other
demographic categories. These groups included trustees
who were female, trustees that held, at least, a
bachelor's degree, trustees with annual incomes above
$50,000, trustees who were members of a community service
organization, trustees with more than four years service
on the board, trustees that held managerial/professional
jobs, and trustees who were Democratic or Independent

Chaotic zone boundary for low free eccentricity particles near an eccentric planet
We consider particles with low free or proper eccentricity that are orbiting
near planets on eccentric orbits. Via collisionless particle integration we
numerically find the location of the boundary of the chaotic zone in the
planet's corotation region. We find that the distance in semi-major axis
between the planet and boundary depends on the planet mass to the 2/7 power and
is independent of the planet eccentricity, at least for planet eccentricities
below 0.3. Our integrations reveal a similarity between the dynamics of
particles at zero eccentricity near a planet in a circular orbit and with zero
free eccentricity particles near an eccentric planet. The 2/7 law has been
previously explained by estimating the semi-major at which the first order mean
motion resonances are large enough to overlap. Orbital dynamics near an
eccentric planet could differ due to first order corotation resonances that
have strength proportional to the planet's eccentricity. However, we find the
corotation resonance width at low free eccentricity is small. Also the first
order resonance width at zero free eccentricity is the same as that for a zero
eccentricity particle near a planet in a circular orbit. This accounts for
insensitivity of the chaotic zone width to planet eccentricity. Particles at
zero free eccentricity near an eccentric planet have similar dynamics to those
at zero eccentricity near a planet in a circular orbit.Comment: accepted for publication in MNRA
Systematic review and network meta-analysis on the efficacy of evolocumab and other therapies for the management of lipid levels in hyperlipidemia
Background: The proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors evolocumab and alirocumab substantially reduce low‐density lipoprotein cholesterol (LDL‐C) when added to statin therapy in patients who need additional LDL‐C reduction.
Methods and Results: We conducted a systematic review and network meta‐analysis of randomized trials of lipid‐lowering therapies from database inception through August 2016 (45 058 records retrieved). We found 69 trials of lipid‐lowering therapies that enrolled patients requiring further LDL‐C reduction while on maximally tolerated medium‐ or high‐intensity statin, of which 15 could be relevant for inclusion in LDL‐C reduction networks with evolocumab, alirocumab, ezetimibe, and placebo as treatment arms. PCSK9 inhibitors significantly reduced LDL‐C by 54% to 74% versus placebo and 26% to 46% versus ezetimibe. There were significant treatment differences for evolocumab 140 mg every 2 weeks at the mean of weeks 10 and 12 versus placebo (−74.1%; 95% credible interval −79.81% to −68.58%), alirocumab 75 mg (−20.03%; 95% credible interval −27.32% to −12.96%), and alirocumab 150 mg (−13.63%; 95% credible interval −22.43% to −5.33%) at ≥12 weeks. Treatment differences were similar in direction and magnitude for PCSK9 inhibitor monthly dosing. Adverse events were similar between PCSK9 inhibitors and control. Rates of adverse events were similar between PCSK9 inhibitors versus placebo or ezetimibe.
Conclusions: PCSK9 inhibitors added to medium‐ to high‐intensity statin therapy significantly reduce LDL‐C in patients requiring further LDL‐C reduction. The network meta‐analysis showed a significant treatment difference in LDL‐C reduction for evolocumab versus alirocumab
Modelling the impact of wind farms on house prices in the UK
This paper discusses the findings from a UK study to determine the likely impact of a wind farm on house prices using a hedonic pricing model. The Government's commitment to wind power has resulted in a massive increase in the number of wind farms sited in the UK. This has led to concerns that their visual and aural presence could have a negative impact on proximate house prices. This paper presents an analysis of 201sales transactions from houses situated within half a mile of a 16 turbine wind farm in Cornwall, UK. Whilst no causal link was established between the presence of the wind farm and house price, there was some evidence to suggest that both noise and flicker from the turbine blades could blight certain property and that the view of countryside enjoyed by the occupier had some value which may be affected by a wind farm.

Šiame darbe aptariami JK atlikto tyrimo rezultatai, kuriuo, taikant hedonistinį kainų modelį, siekta nustatyti galimą vėjo jėgainių poveikį namų kainoms. Vyriausybės parama vėjo energijai paskatino naujo elemento, vėjo jėgainės, atsiradimą aplinkoje; susirūpinta, ar vėjo jėgainių vaizdas ir garsas galėtų neigiamai paveikti namų kainas. Šiame darbe nagrinėjamas 201 prekybinis sandoris, susijęs su namais, pusę mylios nutolusiais nuo Bears Down, Kornvalyje (JK), esančio 16 vėjo jėgainių ūkio. Nors priežastinis ryšys tarp vėjo jėgainių ir namų kainos nepastebėtas, yra įrodymų, kad jėgainės keliamas triukšmas ir menčių mirgėjimas kai kuriems nekilnojamojo turto objektams galėtų pakenkti ir kad gyventojui patikęs kaimo vaizdas gali tapti nebepatrauklus.
