The Political Business Cycle: Endogenous Election Timing & Hyperbolic Memory Discounting
In the models analyzed in this paper, there exists an incumbent politician with one objective, two choices, and voters who remember the past differently. The politician\u27s primary goal is to get reelected, which is done by maximizing the number of votes on the day of election. The politician can increase their chances of reelection if they influence the state of the economy over time and ensure the economy is in its \u27best\u27 state on the days leading up to the election.
In conducting this research, I wanted to study how different rates of memory decay influences the choices the politician makes during the course of their term. Also, I wanted to explore how long a politician would wait to have an election if that were a choice they could make. I found that voters who remember more of the past place a greater constraint on the incumbent leading to moderate fluctuations in the economy and frequent elections
Swimming For More Than Gold: How Swimming Participation and Success in Elite International Swimming Events Can Decrease Drowning Rates Across the World
International swimming provides an opportunity for thousands of swimmers to compete at the highest level of the sport. In this paper, I argue that participation and success in these events can influence drowning rates across the world. My analysis suggests that one of the most notable negative influences on drowning rates is swimming participation in countries that have the smallest roster sizes and the lowest average income levels. My analysis shows that swimming success in the Olympics has a significant positive effect on drowning rates in countries in the middle-income brackets

Plastic with personality: Increasing student engagement with manikins
© 2015 Elsevier Ltd. Background: Simulation allows students to practice key psychomotor skills and gain technical proficiency, fostering the development of clinical reasoning and student confidence in a low risk environment. Manikins are a valuable learning tool; yet there is a distinct lack of empirical research investigating how to enhance engagement between nursing students and manikins. Objective: To describe student perspectives of a layered, technology enhanced approach to improve the simulation learning experience. Educational Framework: Tanner's Model of Clinical Judgment underpins the entire curriculum. This study additionally drew on the principles of narrative pedagogy. Intervention: Across ten teaching weeks, five separate case studies were introduced to students through short vignettes. Students viewed the vignettes prior to their laboratory class. In the labs, manikins were dressed in the props used in the vignettes. Setting: The innovation was trialed in a second year core subject of a Bachelor of Nursing program in a large urban university in the autumn semester of 2014. Data Collection and Analysis: Following ethics approval, students were emailed a participant information sheet. A focus group of nine students was held. The discussion was digitally recorded and transcribed verbatim prior to being subject to thematic analysis. Students' comments (143) about the vignettes in their standard subject specific student feedback surveys were also considered as data. Results: Four themes were identified: Getting past the plastic; knowing what to say; connecting and caring; and, embracing diversity. The feedback indicated that these measures increased students ability to suspend disbelief, feel connected to, and approach the manikins in a more understanding and empathetic fashion. Conclusions: In addition to achieving increased engagement with manikins, other advantages such as students reflecting on their own values and pre-conceived notions of people from diverse backgrounds were realized
Probing the depths of the India-Asia collision: U-Th-Pb monazite chronology of granulites from NW Bhutan
[1] Rocks metamorphosed to high temperatures and/or high pressures are rare across the Himalayan orogen, where peak metamorphic conditions recorded in the exposed metamorphic core, the Greater Himalayan Sequence (GHS), are generally at middle to upper amphibolite facies. However, mafic garnet-clinopyroxene assemblages exposed at the highest structural levels in Bhutan, eastern Himalaya, preserve patchy textural evidence for early eclogite-facies conditions, overprinted by granulite-facies conditions. Monazite hosted within the leucosome of neighboring granulite-facies orthopyroxene-bearing felsic gneiss yields LA-MC-ICP-MS U-Th-Pb ages of 13.9 ± 0.3 Ma. Monazite associated with sillimanite-grade metamorphism in granulite-hosting migmatitic gneisses yields U-Th-Pb rim ages between 15.4 ± 0.8 Ma and 13.4 ± 0.5 Ma. Monazite associated with sillimanite-grade metamorphism in gneiss at structurally lower levels yields U-Pb rim ages of 21–17 Ma. These data are consistent with Miocene exhumation of GHS material from a variety of crustal depths at different times along the Himalayan orogen. We propose that these granulitized eclogites represent lower crustal material exhumed by tectonic forcing over an incoming Indian crustal ramp and that they formed in a different tectonic regime to the ultrahigh-pressure eclogites in the western Himalaya. Their formation and exhumation in the Miocene therefore do not require diachroneity in the timing of the initial India-Asia collision
Extreme alpha-clustering in the 18O nucleus
The structure of the 18O nucleus at excitation energies above the alpha decay
threshold was studied using 14C+alpha resonance elastic scattering. A number of
states with large alpha reduced widths have been observed, indicating that the
alpha-cluster degree of freedom plays an important role in this N not equal Z
nucleus. However, the alpha-cluster structure of this nucleus is very different
from the relatively simple pattern of strong alpha-cluster quasi-rotational
bands in the neighboring 16O and 20Ne nuclei. A 0+ state with an alpha reduced
width exceeding the single particle limit was identified at an excitation
energy of 9.9+/-0.3 MeV. We discuss evidence that states of this kind are
common in light nuclei and give possible explanations of this feature.Comment: 4 pages, 2 figures, 1 table. Resubmission with minor changes for

Miocene surface uplift and orogenic evolution of the southern Andean Plateau (central Puna), northwestern Argentina
We present stable hydrogen-isotope analyses of volcanic glass (δDg) and radiometric ages (U–Pb zircon, U–Th calcite, AMS14C) from deformed sedimentary deposits in the vicinity of the intermontane Pocitos Basin in the central Puna of the Andean Plateau at about 24.5°S. Our results demonstrate 2-km surface uplift since the middle to late Miocene and protracted shortening that persists until the present day, while other sectors of the Puna show evidence for tectonically neutral and/or extensional settings. These findings are at odds with previous studies suggesting near-modern elevations (4 km) of the Puna Plateau since the late Eocene and formation of the intermontane Miocene Arizaro-Pocitos Basin associated with gravitational foundering of a dense lithosphere. Geophysical and geochemical data support the removal of continental lithosphere beneath the Puna, but the timing and mechanisms by which this removal occurs have remained controversial. We hypothesize that intermontane basin formation in the central Puna is the result of crustal shortening since about 20 Ma, followed by rapid surface uplift, likely related to lithospheric delamination
Population of bound excited states in intermediate-energy fragmentation reactions
Fragmentation reactions with intermediate-energy heavy-ion beams exhibit a
wide range of reaction mechanisms, ranging from direct reactions to statistical
processes. We examine this transition by measuring the relative population of
excited states in several sd-shell nuclei produced by fragmentation with the
number of removed nucleons ranging from two to sixteen. The two-nucleon removal
is consistent with a non-dissipative process whereas the removal of more than
five nucleons appears to be mainly statistical.Comment: 5 pages, 6 figure
Spectroscopy of Ti and the systematic behavior of low energy octupole states in Ca and Ti isotopes
Excited states of the nucleus Ti have been studied, via both
inverse-kinematics proton scattering and one-neutron knockout from Ti by
a liquid hydrogen target, using the GRETINA -ray tracking array.
Inelastic proton-scattering cross sections and deformation lengths have been
determined. A low-lying octupole state has been tentatively identified in
Ti for the first time. A comparison of results on low-energy
octupole states in the neutron-rich Ca and Ti isotopes with the results of
Random Phase Approximation calculations demonstrates that the observed
systematic behavior of these states is unexpected.Comment: 7 pages, 8 figure
