description: Precast concrete segmental columns have been popularly adopted in constructions. However, its behavior under dynamic loading especially under impact loading has not been studied yet. This paper investigates the performance of prefabricated segmental columns under impact loads. Precast segmental columns with posttensioning tendon were constructed and tested in laboratory using pendulum impact system. Two segmental columns of the same height but with different number of segment pillars were designed and tested. A conventional monolithic reinforced concrete column was also tested as a reference column to evaluate the performance of the tested segmental columns. The responses of the tested columns were monitored with a high-speed camera. The impact load time history and column displacement time histories were recorded. The test results indicated that comparing to the monolithic column, the segmental columns attracted lower peak impact loads but longer loading duration due to their flexibility. The tested segmental columns also showed better performance against impact load with better self-centring capability, similar energy dissipation capability but less residual displacement and concrete damage.

description: Slow dynamic nonlinearity describes a poorly understood, creep-like phenomena that occurs in brittle composite materials such as rocks and cement. It is characterized by a drop in stiffness induced by a mechanical conditioning, followed by a log(time) recovery. A consensus theoretical understanding of the behavior has not been developed. Here we introduce an alternative experimental venue with which to inform theory. Unconsolidated glass bead packs are studied rather than rocks or cement because the structure and internal contacts of bead packs are less complex and better understood. Slow dynamics has been observed in such systems previously. However, the measurements to date tend to be irregular. Particular care is used here in the experimental design to overcome the difficulties inherent in bead pack studies. This includes the design of the bead pack support, the use of low frequency conditioning, and the use of ultrasonic waves as a probe with coda wave interferometry to assess changes. Slow dynamics is observed in our system after three different methods for low-frequency conditioning, one of which has not been reported in the literature previously.

A Study on the Acquisition of Chinese Directional Complements
Creators: name: lin, lin
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: This paper adopted second language acquisition theories and research methods to investigate how second-language (L2) Chinese learners acquire Chinese directional complements (DCs). It included two main parts: a corpus study and a questionnaire survey. The corpus came from the compositions of 47 Chinese learners at intermediate and advanced levels at a New England university. And the data also included the questionnaire survey of 82 novice, intermediate, and advanced levels’ Chinese learners and 15 native Chinese speakers who study in the same university. The corpus study shows that L2 learners at intermediate and advanced level preferred to use DCs with extended meanings. Moreover, they preferred to combine verb with DC as an entirety rather than placing the object between verb and DC. The error analysis based on the survey data shows that omission errors of DCs accounted for the largest percentage, the percentage of misordering errors and misuse errors were very close, and addition errors were limited. Moreover, a relative acquisition sequence was constructed according to accuracy rate and the usage rate. This acquisition sequence reflects several phenomena: 1) the position of the object influenced the acquisition significantly; 2) some errors were caused vi by interlingual transfer 3) DCs with extended meanings were easier than DCs with directional meanings in some cases; 4) the type of DC was not an important factor to affect the acquisition sequence; 5) L2 learners’ comprehension competence was better than the expression competence at all level; 6)and some DC patterns’ average accuracy increased at higher level, however, the errors of certain DC patterns were fossilized. Since the presentation of the DCs in the textbooks can impact the acquisition. The researcher evaluated the presentation of DCs in participants’ textbooks. There were some deficiencies, such as overwhelming introduction in one lesson, repeating introduction of the same DC, and so on. At last, some implications to teaching DCs were provided based on the findings in previous chapters.

An Imitation of Life: The Strength and Struggle of Women in Murakami Ryū
Creators: name: Erobha, Joseph
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: This thesis argues that the following texts by Murakami Ryū: “Topaz” (1988), Piercing (1997), Audition (1997), and Popular Hits of the Showa Era (1997), are works of transgressive fiction in which the female protagonists respond to the hurtful restrictions and expectations of their gender roles by expressing a dissatisfaction with their “bodies” within these systems, or exacting personal vengeance against the actors of their oppression. It is through such analysis of these characters that the problems faced by women in modern Japan are scrutinized and brought to attention. Even though Murakami himself has written essays that can appear contrary to the complete liberation of Japanese women, his texts are nevertheless significant is drawing attention and sympathy to their problems.

description: Measurements of the electrical response of granular Sn-Ge thin films below the superconducting transition temperature are reported. The addition of an external noise to the magnetic field applied to the sample is found to increase the sample voltage response to a small externally applied ac signal. The gain coefficient for this signal and the signal-to-noise ratio display clear maxima at particular noise levels. We interpret these observations as a stochastic resonance in the percolative Josephson media which occurs close to the percolation threshold.

description: Using precast segmental concrete columns in structures improves the construction efficiency and site safety, leads to better construction quality, and reduces the construction cost, site disruption and environmental impact. The performance of segmental columns to resist earthquake and impact loads is not well studied yet. As a structure might be subjected to such loads during its service life, understanding its resistance capacities is essential for structural safety. This paper reports the findings of our recent studies on the response of precast segmental columns with unbonded prestress tendon. Pendulum impact test and uniaxial cyclic test were conducted on quarter-scale segmental columns. The seismic performance and impact-resistant capacity were evaluated experimentally and compared with conventional monolithic column. Test results showed that under cyclic loading segmental columns exhibited better deformation ability and smaller residual drift; under impact loading segmental columns also showed better self-centring capacity and less residual displacement.

Magnetite Mineralization of the Hammondville Pluton: Poly-Phase Kiruna Type IOCG Magnetite-Apatite Deposits in the Lyon Mountain Granite
Creators: name: Geer, Phillip
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Recent mapping of the Eagle Lake Quadrangle, NY, coupled with whole-rock geochemistry and microscopy has offered insight into the petrogenesis of the magnetite-apatite deposits of the Hammondville mining district in the eastern Adirondack Mountains. This study provides insight into the magmatic history of the ca. 1060-1050 Ma Lyon Mountain Granite (Hammondville Pluton) which is intimately related to, and hosts the deposits in this area. Magnetite seams are commonly surrounded by well layered magnetite gneiss, which typically parallel the seams, although in some outcrops appear to be slightly truncated by them. Mineralization is generally concordant with the weak layering found throughout the rest of the pluton, and similarly lacks a pervasive metamorphic fabric. Sub-solidus deformation is recorded in some localized shear zones that occur in both the seams and host-granite indicating post-crystallization and post-mineralization deformation events. These episodes could have provided conduits for fluids responsible for growing younger zircon that past workers dated and interpreted as a separate time of mineralization. We conclude that magnetite mineralization likely occurred as separate magma, or magnetite rich fluid, injected into the Lyon Mountain Granite either as a syn-magmatic process, or while it was still a crystalline mush.

description: We show that the light shift in atomic clocks can be suppressed using time variation of the interrogation field intensity. By measuring the clock output at two intensity levels, error signals can be generated that simultaneously stabilize a local oscillator to an atomic transition and correct for the shift of this transition caused by the interrogating optical field. These methods are suitable for optical clocks using one- and two-photon transitions, as well as for microwave clocks based on coherent population trapping or direct interrogation. The proposed methods can be widely used both for high-precision scientific instruments and for a wide range of commercial clocks, including chip-scale atomic clocks.

Recursion in Language and Number: Is There a Relationship?
Creators: name: Guerrero, Diego
Publisher: name: University of Massachusetts Amherst

description: Numbers are an important part of the cultural knowledge in the modern world. Its use is fundamental in the conception and development of modern science. There are different sets of numbers called numerical systems. The most frequently used numerical system is the set of natural numbers that is composed of positive integers. Natural numbers have several forms to express the cardinality; the most frequently used is the base-10 number system, it represents the number using base quantities and powers of ten. For example, the current calendar year could be expressed as 2018 ; it’s notation describes the additive and multiplicative composition of base quantities and powers of ten (i.e., 2*103 + 0*102 + 1*101 + 8*100). Also, we can use the notation 11111100010 (i.e., 1*210 + 1*29 + 1*28 + 1*27 + 1*26 + 1*25 + 0*24 + 0*23 + 0*22 + 1*21 + 0*20) to express the same calendar year in base-2. Base number systems express cardinal values using addition and multiplication (two operations defined in natural numbers). However, even if the base-10 system looks close to the human experience; it is an abstract form that requires an external representation to communicate cardinal values. An example of these external representations are cardinal numbers, for example, the number 2018 is represented in English using the words two thousand eighteen, but in Spanish, the cardinal number dos mil dieciocho is used.
Cardinal numbers are a particular case in childhood development because it is the first exposure that children have to the natural numbers. Then the properties of the cardinal numbers could be an essential part of children's number comprehension. But one question arises in this frame: What are the children's capacities that permit the children to understand cardinal numbers? One possibility that is proposed in the field of number cognition is that children’s comprehension of recursion in language triggers the acquisition of natural numbers. For some authors, recursion is an operation that is shared between natural numbers (specifically, cardinal numbers) and language (Barner, 2017; Cheung et al., 2017; Yang, 2016). In this study, we explore the relationship between recursion in language and cardinal numbers. To do so, we study the comprehension of recursive genitives and the production of cardinal numbers in English- speaking and Mandarin-speaking children. The results suggest an association in Mandarin-speaking children, but not in English-speaking children. While these empirical results are inconclusive, I provide a theoretical analysis that gives some insights into how the structure of cardinal numbers could be defined using the concept of recursion.

description: The optomechanical state transfer protocol provides effective, lossy, quantum beam-splitter-like dynamics where the strength of the coupling between the electromagnetic and mechanical modes is controlled by the optical steady-state amplitude. By restricting to a subspace with no losses, we argue that the transition from mode-hybridization in the strong coupling regime to the damped-dynamics in the weak coupling regime, is a signature of the passive parity-time ($\mathcal{PT}$) symmetry breaking transition in the underlying non-Hermitian quantum dimer. We compare the dynamics generated by the quantum open system (Langevin or Lindblad) approach to that of the $\mathcal{PT}$-symmetric Hamiltonian, to characterize the cases where the two are identical. Additionally, we numerically explore the evolution of separable and correlated number states at zero temperature as well as thermal initial state evolution at room temperature. Our results provide a pathway for realizing non-Hermitian Hamiltonians in optomechanical systems at a quantum level.

Inferring Word-Meaning, Morpheme-Based, and Word-Based Second Language Vocabulary Teaching Methodologies
Creators: name: Liu, Qingli
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: In this study, an experiment was conducted to compare the three teaching methods: the inferring word-meaning method, the morpheme-based teaching method, and the word-based teaching method. The results showed that students taught by the inferring word-meaning method outperformed both the students taught by the morpheme-based method and the word-based method in terms of word retention. The possible reason is that the inferring word-meaning section enabled students to pay attention to and spend more time on each word. On the other hand, the disadvantage of the inferring word-meaning method is that it might not be an efficient way to teach a large amount of new vocabulary because it requires sufficient time for students to get involved with the context and the discussion of guessing words. Another drawback is that textbooks are seldom designed for the purpose of inferring word-meaning from context, which means that the teacher has to spend a substantial amount of time editing the dialogues or reading material from the textbook in order to give students more information to help them guess the meaning of each target word. For the morpheme-based teaching method and the word-based teaching method, there were no statistically significant differences observed. Students from both test groups achieved the same percentage of word retention.

description: We discuss the neutrino mass matrix which predicts zero or small values of |V_{13}| in MSSM and found the inequality, sin^2 2theta_{12} <= sin^2 2theta_sol, where sin^2 2theta_{12} is the mixing angle at M_R scale and sin^2 2theta_{sol} is the value determined by the solar neutrino oscillation. This constraint says that the model which predicts a larger value of tan^2 theta_{sol} at M_R than the experimental value is excluded. In particular, the bi-maximal mixing scheme at M_R scale is excluded, from the experimental value tan^2 theta_sol<1. In this model, |V_{13}| and a Dirac phase at m_Z are induced radiatively and turn out to be not small. The effective neutrino mass is expected to be of order 0.05 eV.

description: Manipulating the environment while at the same time measuring key parameters is central to many eco-physiological experiments. Experiments often use climate controlled chambers to change environmental parameters outside their normal range. Often these experiments rely on dedicated hardware, or even buildings, to provide the fine grained control needed to execute these tasks. Smaller scale mobile chambers exist, but fitting equipment is often difficult. Here, we present the description of simple climate controlled chambers outfitted for mass balanced based eco-physiological research. We describe a parts list as well as code to implement a setup which has only centimeters to spare, optimizing space use and minimizing cost.

description: Smallholder poultry as a tool for poverty alleviation has been developed and widely applied in Bangladesh. In this paper, the evolution of the model has been summarized and studies conducted to assess the impact of the poultry model at various stages of its evolution have been critically reviewed. The results indicate that the project has reached the poor though not always ultra poor, the main target of the model, and that participants have benefited positively in terms of income, consumption and nutrition, empowerment of women. However, the results need to be assessed with a high degree of caution because of several methodological limitations of the impact studies. These limitations have been illustrated and suggestions have made for more objective assessment of impact of past projects and for conducting additional research for supporting smallholder poultry as a tool for poverty alleviation.

In this paper, we study the class of Z_2-gradings of Cl(V,g) which are somehow compatible with the multivector structure of the Grassmann algebra over V. A complete characterization for such Z_2-gradings is obtained by classifying all the even subalgebras coming from them. An expression relating such subalgebras to the usual even part of Cl(V,g) is also obtained. Finally, we employ this framework to define spinor spaces, and to parametrize all the possible signature changes on Cl(V,g) by Z_2-gradings of this algebra.

description: In this letter we reconsider the role of Lorentz invariance in the dynamical generation of the observed internal symmetries. We argue that, generally, Lorentz invariance can only be imposed in the sense that all Lorentz non-invariant effects caused by the spontaneous breakdown of Lorentz symmetry are physically unobservable. Remarkably, the application of this principle to the most general relativistically invariant Lagrangian, with arbitrary couplings for all the fields involved, leads by itself to the appearance of a symmetry and, what is more, to the massless vector fields gauging this symmetry in both Abelian and non-Abelian cases. In contrast, purely global symmetries are only generated as accidental consequences of the gauge symmetry.

description: The low energy effective couplings of a four-dimensional $\mathcal{N}=2$ supersymmetric gauge theory to topological invariants of the background gravitational field are described by two functions $A$ and $B$. These two functions play an important role in the study of topologically twisted four-dimensional $\mathcal{N}=2$ supersymmetric gauge theories and in the computation of central charges of $\mathcal{N}=2$ superconformal theories. In this paper, we compute $A$ and $B$ from the partition function in the $Ω$-background for $\mathrm{SU}(2)$ gauge theories. Our results not only confirm the predicted expressions of the effective gravitational couplings, but also give the previously undetermined overall multiplicative factors. We also analyze $A$ and $B$ for the $\mathrm{SU}(N)$ super-Yang-Mills theory, and confirm all the previous predictions.

This written thesis documents how I, accompanied by a team of talented colleagues, conceived of, planned, and began the process of staging Exodus, a museum of between. I begin with an introduction to the theory and influences that shaped the work in its earliest stages. I go on to discuss the major themes of the work, chiefly an excavation of the idea of belonging, and posit a model of theater making modeled on a kaleidoscope, a model that aims to serve as a device through which to see one of our oldest stories with new eyes. I discuss the three lenses through which Exodus will examine the topic of belonging: a museum exhibition comprised of artifacts of mass migration, the first-hand oral testimony of those whose lives have been immediately effected by events of mass migration and a staging of Monteverdi’s opera L’Orfeo I also discuss the role that chance procedure would have played in establishing the tempo and narrative. I then reflect on the impacts of the COVID-19 pandemic that derailed the production of Exodus and suggest alterations to the project that I would make in the event that production should be recommenced in a post pandemic future. While it is difficult to include much assessment of a project that was still in its early stages when aborted, I finish with a critique of the work that had been accomplished and offer a few thoughts on how I view the work now, in light of the work done and global developments.

description: Precast segmental column has been widely used in construction for the past decades as it improves construction efficiency, leads to better construction quality, reduces construction cost, and minimize site disruption and environmental impact. Nevertheless, the performance of precast segmental column under extreme dynamic loading such as impact and blast loading has been seldom studied. This paper presents our recent studies on the response of precast segmental concrete columns with unbonded post-tensioned prestress tendon. Simplified analytical study was used to analyse the response of segmental column. Comparison was made with conventional monolithic column to evaluate the impact resistant performance of segmental column. Concrete shear key with optimized design was introduced to segmental column to improve its lateral shear resistance capacity. FRP wrap was used to strengthen the concrete segment and reduce concrete damage at segmental joints.

description: Currently, the most accurate and stable clocks use optical interrogation of either a single ion or an ensemble of neutral atoms confined in an optical lattice. Here, we demonstrate a new optical clock system based on an array of individually trapped neutral atoms with single-atom readout, merging many of the benefits of ion and lattice clocks as well as creating a bridge to recently developed techniques in quantum simulation and computing with neutral atoms. We evaluate single-site resolved frequency shifts and short-term stability via self-comparison. Atom-by-atom feedback control enables direct experimental estimation of laser noise contributions. Results agree well with an ab initio Monte Carlo simulation that incorporates finite temperature, projective read-out, laser noise, and feedback dynamics. Our approach, based on a tweezer array, also suppresses interaction shifts while retaining a short dead time, all in a comparatively simple experimental setup suited for transportable operation. These results establish the foundations for a third optical clock platform and provide a novel starting point for entanglement-enhanced metrology, quantum clock networks, and applications in quantum computing and communication with individual neutral atoms that require optical clock state control.

description: Beneficial from Fully Convolutional Neural Networks (FCNs), saliency detection methods have achieved promising results. However, it is still challenging to learn effective features for detecting salient objects in complicated scenarios, in which i) non-salient regions may have "salient-like" appearance; ii) the salient objects may have different-looking regions. To handle these complex scenarios, we propose a Feature Guide Network which exploits the nature of low-level and high-level features to i) make foreground and background regions more distinct and suppress the non-salient regions which have "salient-like" appearance; ii) assign foreground label to different-looking salient regions. Furthermore, we utilize a Multi-scale Feature Extraction Module (MFEM) for each level of abstraction to obtain multi-scale contextual information. Finally, we design a loss function which outperforms the widely-used Cross-entropy loss. By adopting four different pre-trained models as the backbone, we prove that our method is very general with respect to the choice of the backbone model. Experiments on five challenging datasets demonstrate that our method achieves the state-of-the-art performance in terms of different evaluation metrics. Additionally, our approach contains fewer parameters than the existing ones, does not need any post-processing, and runs fast at a real-time speed of 28 FPS when processing a 480 x 480 image.

description: The rise and demise of mountain belts, caused by growth, modification, or removal of the continental lithosphere are fundamental processes that influence almost all Earth systems. Understanding the nature, timing, and significance of active processes in the creation and evolution of modern mountain belts is challenged by a lack of middle crustal and lower crustal exposures. Analogues can be found in ancient orogens, whose deeply eroded roots offer a window into deeper processes, yet this record is complicated by overprinting events and complex deformational histories. Research presented herein constrains the tectonic history of multistage Appalachian Orogen, type locality of the Wilson cycle. Data-driven analysis of newly assembled geochronologic, geochemical, and geothermobarometric databases are synthesized with structural fabrics and geophysical imaging to constrain the timing and nature of crustal thickening and thinning events. Results identify a two-stage crustal thickening history in the dominant Acadian Orogeny and suggest the existence of a high elevation, low relief orogenic plateau. This plateau, the Acadian altiplano, formed in central and southern New England by ca. 380 Ma and exited for at least 50 m.y. until underwent orogen parallel collapse ca. 330-310 Ma. Collapse of the plateau likely formed the geophysically observed 12-15 km offset in Moho depth in western New England, and implies that the step has existed for ca. 300 m.y. These data constrain a four-dimensional record of crustal evolution over a period exceeding 100 m.y. Recognition of the Acadian altiplano may have important implications for the genesis of critical Li deposits, paleoclimate, and evolution of the Appalachian basin. Further, present a region that may provide an analogue for studying mid-crustal processes such as partial melting, ductile flow, and plutonism underneath modern plateaus.

Detection of heavy charged Higgs bosons at future Linear Colliders
Creators: name: Moretti, S.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We show how a statistically significant signal of heavy charged Higgs bosons of a general Two-Higgs Doublet Model produced in association with tau-neutrino pairs can be established at future Linear Colliders in the $H^+\to t\bar b\to 4$ jet decay channel. This signature is particularly relevant in the kinematic configuration $\sqrt s\lsim2 M_{H^\pm}$, when the pair production channel $e^+e^-\to H^-H^+$ is no longer available. Here, the initially overwhelming background, constituted by top quark pair production and decay, can vigorously be reduced thanks to a dedicated selection procedure that allows one to extract a signal in a region of several tens of GeV around $M_{H^\pm}\approx \sqrt s/2$, for $\tanβ\gsim40$.

description: Pandorathrips gen. n.
 Diagnosis. Macropterous; antennae 8-segmented (Fig. 216), III–IV with apex constricted, sensoria forked; microtrichia present on III–V. Head wider than long, slightly depressed in front of ocelli, cheeks shorter than compound eyes; eyes without pigmented facets; ocellar setae III outside triangle, lateral or posterolateral to fore ocellus. Pronotum transverse, with no long setae. Mesonotum with paired campaniform sensilla present anteromedially. Metascutum reticulate, MCS present; median pair of setae far from anterior margin. Prosternal ferna entire; basantra without setae; mesothoracic sternopleural sutures complete, furca with weak spinula. Metapre-episternum transverse. Fore wing with costal setae short; first and second veins with setal rows irregular; clavus with 5 veinal and 1 discal setae (Fig. 214). Tergites II–VIII median setae wide apart, close to campaniform sensilla; tergites VI–VII setae S3 much smaller than S4; tergite I with very narrow craspedum, II–VII with broad craspedum, VIII with fine posteromarginal comb arising from broad craspedum but comb interrupted at middle (Fig. 213); tergite IX with two pairs of campaniform sensilla, MD setae long and arising medially; X short with longitudinal split. Sternites without discal setae; II–VI with broad craspedum, VII with craspedum absent medially (Fig. 212), all setae in front of posterior margin. Male sternites III–VII each with a small transverse pore plate (Fig. 215).
 Type species Pandorathrips ascius sp. n.
 Comments. The only species placed in this new genus differs from all Anaphothrips species in having tergal craspeda, and also in having one discal seta on the fore wing clavus. It differs from similar looking Neotropical anaphothripines, such as Desertathrips De Borbon and Ameranothrips Mound & Marullo, in having males with typical pore plates on several sternites. The form of the posteromarginal comb on the ninth tergite is almost unique, although similar to that of Lomatothrips paryphis from New Zealand (Mound & Walker, 1982: Fig. 203). However, the genus Lomatothrips, despite the presence of tergal craspeda, is considered to be closely related to the Frankliniella genus group (Mound, 2006).

description: We perform a multivariate analysis of Higgs-pair production in $HH \to b\bar b γγ$ channel at the HL-LHC to probe the trilinear Higgs self--coupling $λ_{3H}$, which takes the value of 1 in the SM. We consider all the known background processes. Also, for the signal we are the first to adopt the most recent event generator of POWHEG-BOX-V2 to exploit the NLO distributions for Toolkit for Multivariate Data Analysis (TMVA), taking account of the full top--quark mass dependence. Through Boosted Decision Tree (BDT) analysis trained for $λ_{3H}=1$, we find that the significance can reach up to 1.95 with about $9$ signal and $18$ background events. In addition, the Higgs boson self-coupling can be constrained to $1.00 < λ_{3H} < 6.22$ at 95\% confidence level (CL). We also perform a likelihood fitting of $M_{γγbb}$ distribution and find the $1σ$ confidence interval (CI) of $0.1 < λ_{3H} < 2.2\, \cup\,5.4 < λ_{3H} < 6.6$ for the $λ_{3H}=1$ nominal set. On the other hand, using BDTs trained for each value of $λ_{3H}$, we find a bulk region of $0.5

description: The aims of our study were to molecularly assess some seedy strains of Alamar Apricot Rootstock using SCoT and ISSR techniques. In addition, assessment of the expression of P5CS gene with assay of some stress-related phytochemical parameters under salinity stress. These strains were irrigated with salt solution for 6 months from June 2016, only eight strains continued to grow under salinity stress. ISSR and SCoT techniques revealed polymorphic patterns and confirmed to be valid in discriminating these eight strains. SCoT technique was better than ISSRs in assessment for molecular diversity and discrimination capacity for all studied seedy strains. However, a significant positive correlation was found only between distances based on ISSR data and Euclidian distances based on stress-related phytochemical parameters data. These strains showed higher values than control for the studied parameters, specially A3 being the best strain in all parameters, in addition to showing a significantly increase in P5CS gene expression compared to control. Also, A3 was distinguished by a few ISSR unique markers. This, suggesting that, these markers may be used as markers assisted selection in the improvement of salinity tolerance. In addition, the possibility of utilizing this strain through other studies as a source of salinity tolerance in Alamar apricot rootstock.
The Welfare States: Examining U.S. State-Level Benefits For Families With Children, 1987-2015
Creators: name: Huaqui, Anthony

description: Welfare state scholars have amassed competing theoretical explanations for the development of welfare policies. When considering the U.S. case, a discussion of federalism is central to these theoretical examinations. How power in policymaking is distributed amongst the varying levels of government is influential in the construction of the U.S. welfare state. Standard quantitative approaches to U.S. welfare research have offered a limited analysis of how theoretical explanations change after historical moments of welfare reform. In this study, I examine the institutional changes introduced to U.S. welfare in 1996 by way of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA). This study examines the changes in welfare maximum benefit levels for a 3-person family from 1987-2015. However, I apply an alternative quantitative approach to studying the effects PRWORA has had on benefit maximums by splitting models into two separate time periods and running analyses separately: pre-PRWORA (1987-1996) and post-PRWORA (1997-2015). By applying this methodological approach, I demonstrate how the influence of different sets of theories change after institutional reforms, such as PRWORA. The results offer new insights to the temporal applicability of different theoretical explanations and the construction of social citizenship.
