description: We present a scaling theory describing the collapse of a homopolymer chain in poor solvent. At time t after the beginning of the collapse, the original Gaussian chain of length N is streamlined to form N/g segments of length R(t), each containing g ~ t monomers. These segments are statistical quantities representing cylinders of length R ~ t^{1/2} and diameter d ~ t^{1/4}, but structured out of stretched arrays of spherical globules. This prescription incorporates the capillary instability. We compare the time-dependent structure factor derived for our theory with that obtained from ultra-large-scale molecular dynamics simulation with explicit solvent. This is the first time such a detailed comparison of theoretical and simulation predictions of collapsing chain structure has been attempted. The favorable agreement between the theoretical and computed structure factors supports the picture of the coarse-graining process during polymer collapse.

Subjects: subject: 20399 Classical Physics not elsewhere classified
subject: FOS: Physical sciences

description: The advent of new two-dimensional materials, and the ability to create van der Waals heterostructures has further intensified research interest in graphene. At the
heart of these heterostructures is the proximity eff ect, where one material synergistically inherits the properties of the material adjacent to it. The capabilities of graphene can thus be greatly enhanced by tailoring in new properties whilst preserving its excellent implicit properties. Of considerable interest is the creation of a long range magnetic order in graphene by means of a magnetic proximity eff ect from an
adjacent two-dimensional magnet. Such a system has industrial applications in the field of low power logic and memory devices. It is also of curiosity to scientists as
it harbours novel topological states, and could help understand the manifestation of phenomena such as magnetism in two dimensions. Here we fabricate devices made out of heterostructures of graphene and two-dimensional magnets. We characterize the electronic and magnetic properties of such devices using electronic transport, capacitance and optics. The majority of eff orts have been directed towards creating clean interfaces, and preserving the magnetic materials, which are extremely chemically sensitive to ambient conditions. We demonstrate the presence of interfacial physics in these devices that lead to the enhancement in the magnetic order of the two-dimensional magnet.
Gravitational Waves from Supernova Mass Loss and Natal Kicks in Close Binaries

description: Some fraction of compact binaries that merge within a Hubble time may have formed from two massive stars in isolation. For this isolated-binary formation channel, binaries need to survive two supernova (SN) explosions in addition to surviving common-envelope evolution. For the SN explosions, both the mass loss and natal kicks change the orbital characteristics, producing either a bound or unbound binary. We show that gravitational waves (GWs) may be produced not only from the core-collapse SN process, but also from the SN mass loss and SN natal kick during the pre-SN to post-SN binary transition. We model the dynamical evolution of a binary at the time of the second SN explosion with an equation of motion that accounts for the finite timescales of the SN mass loss and the SN natal kick. From the dynamical evolution of the binary, we calculate the GW burst signals associated with the SN natal kicks. We find that such GW bursts may be of interest to future mid-band GW detectors like DECIGO. We also find that the energy radiated away from the GWs emitted due to the SN mass loss and natal kick may be a significant fraction, ${\gtrsim}10\%$, of the post-SN binary's orbital energy. For unbound post-SN binaries, the energy radiated away in GWs tends to be higher than that of bound binaries.

description: This paper explores the likely impact of emissions trading design on transaction costs. Transaction costs include both the costs for the private sector to comply with the scheme rules and the costs of scheme administration. In economic theory transaction costs are often assumed to be zero. But transaction costs are real costs and there is no reason for treating them differently to other costs. Thus, in setting up an emissions trading scheme, transaction costs have to be taken into account in order to recommend a cost efficient design. In this paper, we compare transaction costs of different schemes such as the European Emissions Trading Scheme and the Clean Development Mechanism (CDM) to asses the hypothesis that cap and trade schemes have lower transaction costs than project-based mechanisms such as the CDM.
Design of Children's Event and Cutural Center in Osu, Accra, Ghana
Creators: name: somuah, rudi
Publisher: name: University of Massachusetts Amherst
Year: 2015

description:  Osu, a district in central Accra, Ghana, is known for its busy commercial enterprises, countless restaurants and vibrant nightlife. Osu remains prominent in Ghana and also globally for a variety of reasons. One of such reasons is that it is arguably Ghana's most contemporary setting; second to no other location in the entire country. Osu is also the site of Ghana's seat of government- The Colonial era Christiansburg Castle which houses the president’s office and official residence. The town also plays host to several western diplomatic missions and embassies including the American Embassy. In addition to its 5 star hotels, nightclubs and multiple drive-through restaurants, what really makes Osu prominent in Ghana and elsewhere is its multiple establishments for children, such as the Osu Children's Home, and its continued philanthropy towards the betterment of the plight of displaced and underprivileged children. This thesis proposes and showcases the design of a children’s event and cultural center in Osu; to celebrate and enhance its legacy of child philanthropy. Planning and vi generative design aspects of the built artifact such as programming, site studies, and the collection of potentials for form generation, will be exhaustively addressed in this thesis.

description: We show that in see-saw models with bimaximal lepton mixing at the GUT scale and with zero CP phases, the solar mixing angle theta_{12} generically evolves towards sizably smaller values due to Renormalization Group effects, whereas the evolution of theta_{13} and theta_{23} is comparatively small. The currently favored LMA solution of the solar neutrino problem can thus be obtained in a natural way from bimaximal mixing at the GUT scale. We present numerical examples for the evolution of the leptonic mixing angles in the Standard Model and the MSSM, in which the current best-fit values of the LMA mixing angles are produced. These include a case where the mass eigenstates corresponding to the solar mass squared difference have opposite CP parity.

In the case of a closed genus-1 surface, we derive optimal error bounds with respect to the $L^2$-- and $H^1$--norms for a fully discrete approximation. We perform convergence experiments to confirm the theoretical results, and also present numerical simulations for some genus-0 and genus-1 surfaces, including for the Angenent torus.

The optical activity model we present has two phenomenological gyration parameters, within which we analyze three model cases, namely, an exactly integrable model, the Landau-Lifshitz model and the Fedorov model, these latter two are solved in the short wavelength approximation. The model background is a gravitational pp-wave. The solutions show that the optical activity induced by curvature leads to Faraday rotation.

description: Nearby clusters of galaxies, z<0.1, are cosmic structures still under formation. Understanding the thermodynamic properties of merging clusters can provide crucial information on how they grow in the local universe. A detailed study of the intra-cluster medium (ICM) properties of un-relaxed systems is essential to understand the fate of in-falling structures and, more generally, the virialization process. We analyzed a mosaic of XMM-Newton observations (240 ks) of the Lyra system (z=0.067) that shows a complex dynamical state. We find the main cluster RXC J1825.3+3026 to be in a late merger phase, whereas its companion CIZA J1824.1+3029 is a relaxed cool-core cluster. We estimate a mass ratio of ~1:2 for the pair. No diffuse X-ray emission is found in the region between them, indicating that these clusters are in a pre-merger phase. We found evidence of a galaxy group infalling on RXC J1825.3+3026 in an advanced state of disruption. The Southern Galaxy, one of the brightest galaxies in the Lyra complex, was very likely at the center of the infalling group. This galaxy has a gaseous corona indicating that it was able to retain some of its gas after the ram-pressure stripping of the intra-group medium. In this scenario the diffuse emission excess observed southwest of RXC J1825.3+3026 could be due to gas once belonging to the group and/or to cluster ICM dislocated by the passage of the group. Finally, we identified three high-velocity galaxies aligned between RXC J1825.3+3026 and the SG, two of these showing evidence of gas stripped from them during infall. We estimate them to be currently falling onto the main cluster at an infall velocity of ~ 3000 km/s. Our study of the Lyra complex provides important clues about the processes presiding over the virialization of massive clusters in the local Universe.

Homeowner Willingness to Adopt Low-Impact Development Practices in the Ipswich River Watershed: Opportunities and Barriers
Creators: name: Stacy, Johanna R
Publisher: name: University of Massachusetts Amherst
Year: 2015

description: The Ipswich River watershed has experienced increasing urbanization in recent years. The river, which supplies water to over 300,000 residents (twice the watershed’s population), was considered one of the 10 Most Endangered Rivers in the U.S. in 2003 due to seasonal low-flow and no-flow events. Seasonal outdoor water restrictions have curbed residential demand; however, impervious surfaces and municipal sewer systems direct much of the runoff outside the watershed. Low-impact development (LID) practices, specifically those that infiltrate runoff, have the potential to keep more water in the watershed, and increase baseflows in the river.
This study seeks to ascertain the barriers and motivations that exist to LID adoption. A paper survey including Likert-scale questions and a photo preference component was sent to 1,000 homeowners in the watershed. Analysis of responses employed factor analysis and means comparisons to compare responses between concerned homeowners (those who belonged to the local watershed association) and randomly-selected homeowners.
Income and educational attainment were significant variables in both aesthetic preferences and willingness to adopt LID practices. Perceived cost of landscape changes and concern about disease-carrying pests also surfaced as barriers to residential adoption. The findings emphasize alternate strategies for land use planners, landscape professionals and environmental organizations to promote behavioral changes in the way residential landscapes are managed, and policies municipalities could adopt to implement more widespread use of LID practices. More widespread understanding and appreciation of the multiple benefits of rain LID landscapes could also serve all three groups.

description: Global Climate Models are key tools for predicting the future response of the climate system to a variety of natural and anthropogenic forcings. Here we show how to use statistical mechanics to construct operators able to flexibly predict climate change for a variety of climatic variables of interest. We perform our study on a fully coupled model - MPI-ESM v.1.2 - and for the first time we prove the effectiveness of response theory in predicting future climate response to CO$_2$ increase on a vast range of temporal scales, from inter-annual to centennial, and for very diverse climatic quantities. We investigate within a unified perspective the transient climate response and the equilibrium climate sensitivity and assess the role of fast and slow processes. The prediction of the ocean heat uptake highlights the very slow relaxation to a newly established steady state. The change in the Atlantic Meridional Overturning Circulation (AMOC) and of the Antarctic Circumpolar Current (ACC) is accurately predicted. The AMOC strength is initially reduced and then undergoes a slow and only partial recovery. The ACC strength initially increases as a result of changes in the wind stress, then undergoes a slowdown, followed by a recovery leading to a overshoot with respect to the initial value. Finally, we are able to predict accurately the temperature change in the Northern Atlantic.

description: Education sciences research has showed that learning is a complex interaction between individuals and their surrounding world. The simplification of learning complexity has been commonly assumed in local and traditional ecological knowledge (LEK/TEK) research. Based on a modern learning theory, this article describes learning complexity behind the LEK/TEK held by fishers and farmers in Sweden. It leads to the introduction of the concept of biocultural learning that contributes to this field by giving details to this complexity. From a biographic approach, this research combines case studies, in-depth biographical narrative interviews, participant observations and the analysis of personal blogs and family pictures as data collection methods. This combination reveals the interconnection between professional knowledge about nature, identity construction and emotional bonds to nature. This article highlights the value of giving professional status to LEK/TEK and discusses the need to promote and strengthen biocultural learning in different society sectors.

description: The prevalence of chronic kidney disease (CKD) is gradually increasing in the elderly population. At the same time, frailty has become one of the research hotspots in the field of geriatrics. Bibliometric analyses help to understand the direction of a field. Therefore, this study aimed to analyze the status and emerging trends of frailty in CKD patients. The Web of Science Core Collection (WoSCC) database was screened for relevant literature published between 1 January 2000 and 31 December 2021. Next, publications were analyzed for information including authors, journals, cited references, citing journals, institutions, countries and regions, high-frequency keywords and co-citations using VOSviewer, Microsoft Excel, and R software. A total of 2223 articles were obtained, from which 613 relevant articles were selected based on title and abstract screening. There was an upward trend in the number of annual publications and Johansen KL was considered the most contributing author in the field. The Clinical Journal of the American Society of Nephrology was the most productive research journal. Johns Hopkins University is the most published organization. The United States is the global leader in the field and contributes the most to research. Research hotspots focus on epidemiological studies of frailty and frailty intervention. This study presents a comprehensive bibliometric analysis of CKD and frailty research. Key findings highlight the current focus on early screening and assessment of frailty in CKD patients, as well as physical function interventions in frail patients.

description: Using a sample of 70 924 stars from the second data release of the GALAH optical spectroscopic survey, we construct median sequences of [X/Mg] vs. [Mg/H] for 21 elements, separating the high-$α$/``low-Ia'' and low-$α$/``high-Ia'' stellar populations through cuts in [Mg/Fe]. Previous work with the near-IR APOGEE survey has shown that such sequences are nearly independent of location in the Galactic disk, implying that they are determined by stellar nucleosynthesis yields with little sensitivity to other chemical evolution aspects. The separation between the two [X/Mg] sequences indicates the relative importance of prompt and delayed enrichment mechanisms, while the sequences' slopes indicate metallicity dependence of the yields. GALAH and APOGEE measurements agree for some of their common elements, but differ in sequence separation or metallicity trends for others. GALAH offers access to nine new elements. We infer that about $75\%$ of solar C comes from core collapse supernovae and $25\%$ from delayed mechanisms. We find core collapse fractions of $60-80\%$ for the Fe-peak elements Sc, Ti, Cu, and Zn, with strong metallicity dependence of the core collapse Cu yield. For the neutron capture elements Y, Ba, and La, we infer large delayed contributions with non-monotonic metallicity dependence. The separation of the [Eu/Mg] sequences implies that at least $\sim30\%$ of Eu enrichment is delayed with respect to star formation. We compare our results to predictions of several supernova and AGB yield models; C, Na, K, Mn, and Ca all show discrepancies with models that could make them useful diagnostics of nucleosynthesis physics.

description: Dryland salinity has resulted from clearing of deep-rooted plant species for farming. Farm diversification with trees and perennial pasture species may therefore reverse this problem. However, current opinion is that existing land uses are close to economic optimum and therefore changes involving perennials may not be viewed as desirable. Socially there is a trade-off between the opportunity cost of changing existing land use with the perennials and the current salinity reduction targets. In this context, this paper investigates the economic implications of key decision parameters of farmers on their response to achieve farm diversification involving farming with the perennials. This research aims to model diversification and supply responses of, in particular, wheat across the Australian wheat-sheep zone, and between the regions of NSW and Western Australia.

description: A relativistic resonance which was defined by a pole of the $S$-matrix, or by a relativistic Breit-Wigner line shape, is represented by a generalized state vector (ket) which can be obtained by analytic extension of the relativistic Lippmann-Schwinger kets. These Gamow kets span an irreducible representation space for Poincaré transformations which, similar to the Wigner representations for stable particles, are characterized by spin (angular momentum of the partial wave amplitude) and complex mass (position of the resonance pole). The Poincaré transformations of the Gamow kets, as well as of the Lippmann-Schwinger plane wave scattering states, form only a semigroup of Poincaré transformations into the forward light cone. Their transformation properties are derived. From these one obtains an unambiguous definition of resonance mass and width for relativistic resonances. The physical interpretation of these transformations for the Born probabilities and the problem of causality in relativistic quantum physics is discussed.

description: Environmental conservation is intimately tied to both economic development and sustainable management of natural resources. Convergence and complementarity of environmental and developmental functions of forest management and their sustainable utilisation is a challenge for both developing and industrialised countries. Nationally forests are seen as a consumable commodity but at an international level forests are scarce resources and their non-commodity values matters particularly with respect to climate change mitigation and bio-diversity conservation. In this regard this paper reviews two aspects: an assessment of influence of non-forest sector (external) policies on forests; the initiatives taken by international community for forestry development in developing countries.
Navigating the Interim

Year: 2015

description: Navigating the Interim attempts to build a framework for the ways in which visual art, media studies, and forms of social practice might intermingle within a career in the arts, as well as within a thorough art education curriculum. From broad theoretical analysis to the specificity of technical exercises and prompts, this paper serves as a roadmap for the ways in which production, teaching, and organizing might begin to merge into a single holistic practice. The author’s projects provide an anchor from which to analyze the various conceptual trajectories of art that have stemmed from modernism throughout the 20th century, as well as to challenge the anti-aesthetic phenomenon that has emerged out of this evolution, which has influenced paradigms within art education and leads to an analysis of the author’s own creative impulses, such as media activism, noise-based and appropriative tactics, and concerns about Debordian Spectacle. These self-analyses and reflections are situated within various binary oppositions: object-action, opacity-transparency, deconstruction-enstrangement, replacement-extension, and static-progressive.

description: While a substantial literature in economics and finance has concluded that women are more risk averse than men, this conclusion merits reconsideration. Drawing on literatures in statistics and cognitive science, this essay discusses the important difference between drawing conclusions based on statistical inference, which concerns aggregates such as mean scores, and generalization, which posits characteristics of individuals classified into kinds. To supplement findings of statistical significance, quantitative measures of substantive difference (Cohen's d) and overlap (the Index of Similarity) are computed from the data on men, women, and risk used in 28 published articles. The results are considerably more mixed and overlapping than might be expected. Paying attention to empirical evidence that challenges subjective cultural beliefs about sex and risk has implications for labor economics, finance, and the economics of climate change.

description: It is shown that anomalous properties of UGe_2 can be understood in a unified way on the basis of a single assumption that the superconductivity is mediated by the coupled SDW and CDW fluctuations induced by the imperfect nesting of the Fermi surface with majority spins at T=T_x(P) deep in the ferromagnetic phase. Excess growth of uniform magnetization is shown to develop in the temperature range T

description: Photonic lattices are usually considered to be limited by their lack of methods to include interactions. We address this issue by introducing mean-field interactions through optical components which are external to the photonic lattice. The proposed technique to realise mean-field interacting photonic lattices relies on a Suzuki-Trotter decomposition of the unitary evolution for the full Hamiltonian. The technique realises the dynamics in an analogous way to that of a step-wise numerical implementation of quantum dynamics, in the spirit of digital quantum simulation. It is a very versatile technique which allows for the emulation of interactions that do not only depend on inter-particle separations or do not decay with particle separation. We detail the proposed experimental scheme and consider two examples of interacting phenomena, self-trapping and the decay of Bloch oscillations, that are observable with the proposed technique.

A Financial Crisis Manual Causes, Consequences, and Lessons of the Financial Crisis

subject: Consequences

description: On the fifth anniversary of the beginning of the Great Recession, there is still no consensus on the lessons to be gleaned from the lingering crisis. What provoked the largest financial and economic collapse in decades? While the housing bubble and subprime mortgage lending boom provide clear proximate causes, skewed financial sector incentives, errant economic assumptions, and inequitable socioeconomic structures laid the groundwork for crisis. The complex web of underlying factors extends from a 1960s-era economic hypothesis to the deregulation of interstate banking to a shift in how Wall Street CEOs are paid. This paper traces that causal web for a generalist audience, summarizes how the financial crisis morphed into an economy-wide recession, and synthesizes proposals for how to prevent its recurrence. Such proposals are not limited to efforts to rein in Wall Street, as exemplified by the sweeping Dodd-Frank financial reform law, but also include initiatives to harness Wall Street’s vast resources for the needs of the real economy. Meanwhile, the crisis amplified calls to address crisisprone disequilibria in the U.S. economy, and to alter the study of economics itself. As the country continues to grapple with the economic fallout of financial meltdown, such proposals merit continued discussion.

Building a Democratic Consciousness in Taiwan: An Analysis of Lung Ying-tai’s Political Essays Over Three Decades (1984–2003)
Creators: name: Bauer, Conrad W
Publisher: name: University of Massachusetts Amherst
Year: 2015

description: Throughout her writing career, the Taiwan intellectual Lung Ying-tai (1952– ) has elaborated a distinct vision of how her country could realize the civic foundations of a democratic society. This ambition began with “Wild Fire,” an editorial column that ran in the Taiwan newspaper The China Times from 1984 to 1986, which was later compiled into a 1986 book, Wild Fire Collection. At this time, Taiwan’s political structure had just begun a process of liberalization. Under increasing international and domestic pressure, the ruling Kuomintang (KMT) party eased its authoritarian control over the island. Lung took advantage of this unique moment, and, during Taiwan’s radical political reorganization, helped lay the foundations for a civil society based on democratic values. Lung’s vision of Taiwan’s burgeoning civil society centered on a strong democracy rooted in individual empowerment; an educated citizenry; and a native identity tied to the island.
As Taiwan has continued its process of liberalization through the 1990s and into the 21st century, Lung has remained an outspoken voice in Taiwan’s political and cultural development. This thesis traces the themes that Lung first introduced in Wild Fire Collection through two later essay collections, Thinking Back on the Last Hundred Years (1999) and When Facing the Sea (2003). The issues that Lung discussed in “Wild Fire” have only become more relevant as Taiwan’s society puts into practice the democratic values that Lung called for in the mid-1980s. Meanwhile, globalization and China’s rise have brought the debate over Taiwan’s cultural identity to the fore.
Momentum distribution of relativistic nuclei with Hartree-Fock mesonic correlations

description: The impact of Hartree-Fock correlations on the nuclear momentum distribution is studied in a fully relativistic one boson exchange model. Hartree-Fock equations are exactly solved to first order in the coupling constants. The renormalization of the Dirac spinors in the medium is shown to affect the momentum distribution, as opposed to what happens in the non-relativistic case. The unitarity of the model is shown to be preserved by the present renormalization procedure.

Human Capital, Employment and Subjective-Objective Poverty: A Micro Case Study of Nepal
Creators: name: Pradhan, Tejesh
Publisher: name: University of Massachusetts Amherst
Year: 2015

description: This thesis derives an alternative subjective-objective poverty line (SPL) using self-reported qualitative assessments of perceived adequacy for different categories of consumption namely, food, housing and clothing. Modeling the probability of reporting that actual consumption in each category is adequate, I find that actual measures of consumption are highly significant predictors of perceived consumption adequacy. The perceived adequacy for different consumption components respond more elastically to spending on the corresponding category of goods than to that on other types. The results suggest that the implied subjective poverty lines and regional profiles are different from those predicted by popular objective methods.
This thesis also estimates the effects of human capital, employment and basic facilities on household poverty status in Nepal. Delving into this topic seems very policy relevant for the country, where there is a huge need of public education and unemployment insurance programs. To investigate this causal relationship, I use the Living Standards Measurement Survey Data for the year 2010/11, which includes information on past and present educational attainment, current employment, and availability and status of infrastructure in different communities of the country. I find that higher educational attainment, employment and improved perceived status of public amenities contribute to higher subjective wellbeing and reduced likelihood of poverty, controlling for value of assets owned, socio-demographic attributes and geographic location.
Galaxy Clusters in the Presence of Substructure

description: My thesis focused on developing an end-to-end program for dynamical analyses of galaxy clusters. The main interest of the thesis is to develop a dynamical mass estimator used for galaxy clusters that has the capability to account for substructure which is currently a limitation on most dynamical mass estimators. Through already established collaborations, I had access to a cutting-edge multi-object spectrograph, the Michigan/Magellan Fiber System (M2FS), on the 6.5m Clay-Magellan Telescope in Chile; therefore, a signi ant portion of my thesis involved the collection, data
reduction, and spectral analysis of new galaxy spectra. As part of this collaboration, I became a core member of the M2FS observation team, which sent me to Chile about
a half dozen times to aid in the observations with M2FS.
The early portions of my thesis project focused on the handling of newly obtained galaxy spectra with M2FS. The first M2FS observations of galaxies within clusters
were collected in November 2013 as a pilot program for testing this instruments capabilities at observing unresolved stellar populations. My goal with this portion of
the project was to familiarize myself with the M2FS instrument and it's observations as well as to learn how to reduce the collected data. As part of this familiarization,
I learned first-hand how to observe with M2FS and aid in the collection of other observations over a variety of scienti fic interests. While reducing my own observations, I developed a front-end GUI to simplify the data reduction process and help expedite the reduction of future observations. Although, the data reduction pipeline I developed works well at reducing a subset of M2FS observations, I was unable generalize the pipeline fully to handle all M2FS configurations. This is due to variations between configurations such as resolution settings, multi-order spectra, and wavelength coverages. I also helped in the collection of spectra with M2FS over a range of scientifi c
purposes. For projects more related to my own work, I collected spectra for galaxies within the clusters Abell 1689, MACS0429, and CL 1301. MACS0429 was part of my own research project and so I detail in this thesis the targeting, observation, data reduction, and spectral fi ts.
