Reactions to Interpersonal Feedback: Self-Concept Change And Affiliation Choice In Individuals With Low Self-Esteem, Depressive, And Borderline Personality Disorder Symptoms
Creators: name: Mitchell, Jenny E.
Publisher: name: American University
Year: 2023

description: Though some previous research has demonstrated that individuals with low self-esteem, borderline personality disorder, and depressive symptoms process interpersonal feedback differently such that they tend to prefer more negative evaluations than controls do, other research has delineated certain limitations and conditions under which these biases are not demonstrated. The current study aimed to address whether or not affiliation preferences and processing differences by those with borderline personality disorder symptoms are mediated by self-esteem. This study also implements a complex paradigm with negative and positive feedback on both strengths and weaknesses to assess whether different feedback is preferred depending on individuals’ own feelings about traits. Additionally, this study sought to determine mechanisms underlying previous research showing that individuals with borderline personality disorder have a negative bias such that they incorporate more negative feedback into their self-concept than controls do. The current study implemented valenced structured feedback from four false evaluators to examine how individuals with borderline personality disorder symptomology differentially react to interpersonal feedback in terms of affiliation choices and self-concept change. Undergraduate participants (n = 107) wrote about their strengths and weaknesses, received feedback from four evaluators, ranked their preference and perceptions of evaluators, and rated and re-rated themselves as they compared to others on the traits they had chosen. Results indicated that, when evaluator feedback amplified weaknesses, individuals with higher identity disturbance and individuals with higher difficulties in emotion regulation found feedback to be significantly more believable than did individuals low in identity disturbance and individuals low in difficulties in emotion regulation. Results also demonstrated biased incorporation of feedback such that individuals with greater difficulties in regulating emotions were more likely to worsen their self-views about their weaknesses after receiving overall neutral feedback.

description: This study sought to examine relative importance of the different channels of the monetary transmission mechanism in Zambia. Vector Autoregressive Methods are used to examine the strength of each channel of monetary policy, namely interest rate, Exchange rate, credit and asset price channels. Results indicate that the exchange rate and credit are effective channels of monetary policy transmission in Zambia. Further, the study shows that although the interest channel is working it is weak while the equity or asset price channel is not important. From a policy perspective, these results imply that Central Bank is required to continuously monitor developments in the credit and conditions in foreign exchange markets in order to design effective monetary policies. In addition, concerted efforts are needed towards enhancing the asset/equity price channel in Zambia to make monetary policy to be more effective.

description: Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semi-metals, but only in a relatively few cases has this goal been realized. In this work, we present a systematic high-field quantum oscillation study up to 35 T on ZrSiS, a textbook example of a nodal-line semimetal with only linearly dispersive bands crossing the Fermi energy. The topology of the Fermi surface is determined with unprecedented precision and all pockets are identified by comparing the measured angle dependence of the quantum oscillations to density functional theory calculations. Comparison of the Shubnikov-de Haas and de Haas-van Alphen oscillations at low temperatures and analysis of the respective Dingle plots reveal the presence of significantly enhanced scattering on the electron pocket. Above a threshold field that is aligned along the c-axis of the crystal, the specific cage-like Fermi surface of ZrSiS allows for electron-hole tunneling to occur across finite gaps in momentum space leading to quantum oscillations with a complex frequency spectrum. Additional high-frequency quantum oscillations signify magnetic breakdown orbits that encircle the entire Dirac nodal loop. We suggest that the persistence of quantum oscillations in the resistivity to high temperatures is caused by Stark interference between orbits of nearly equal masses.

description: We consider gauged maximal supergravities with CSO(p,q,r) gauge groups and their relation to the branes of string and M-theory. The gauge groups are characterised by n mass parameters, where n is the transverse dimension of the brane. We give the scalar potentials and construct the corresponding domain wall solutions. In addition, we show the higher-dimensional origin of the domain walls in terms of (distributions of) branes. We put particular emphasis on the CSO(p,q,r) gauged supergravities in D=9 and D=8, which are related to the D7-brane and D6-brane, respectively. In these cases, twisted and group manifold reductions are shown to play a crucial role. We also discuss salient features of the corresponding brane distributions.

title: The Geology of the Moon: Geochemistry and Petrology of Lunar Basalts
Creators: name: Hallis, Lydia Jane
Publisher: name: The Open University
Year: 2010

description: The aim of this research is to determine any genetic relationships between high- and lowTi lunar basalts in terms of petrology, mineralogy, geochemistry and geochronology, using a set of Apollo samples. SEM images, mineral compositions, and major- and trace-element data indicate that the high and low-Ti mare-basalts form two distinct groups, both mineralogically and chemically. Apollo 12 and 15 low-Ti basalts were produced from similar source regions, whereas the Apollo 11 and 17 basalts show greater source region compositional variation. Pb-Pb age dating of low-Ti and high-Ti samples confirm previous observations indicating the former are generally younger than the latter. Geochemical modelling suggests that the low-Ti basalts formed from < 10 % partial melting of a depleted Moon source, followed by olivine fractionation. The high-Ti basalts were probably formed as a result of < 15 % partial melting of relatively incompatible-elementenriched source regions, followed by multi-phase crystal fractionation. The REE content of Apollo 14 low-Ti, high-AI basalt 14053 can be reconstructed by ~ 10 % partial melting of a depleted Moon source, followed by olivine fractionation and 1.5 % simultaneous assimilation of a KREEPy/granitic crustal component. The REE contents of Apollo 11 high-Ti, high-K basalts match well with 10 % KREEP assimilation, along with multi-phase fractionation from a parental melt similar to Apollo 11 orange glass. Setting aside the different parental melt evolutions, bulk-rock elemental evidence clearly indicates that the high- and low-Ti mare-basalts were produced by compositionally different source regions. This conclusion is supported by different oxygen isotope compositions of the high- and low-Ti basalts. However, oxygen isotope data implies that rather than a bi-modal system, a mare-basalt compositional continuum exists. This continuum fits well with the heterogeneous cumulate source model for mare-basalt formation. Our oxygen isotope data reveal no detectable difference between the 0 of the Earth and Moon, with implications for the viability of the giant impact origin of the Moon.

Tiling large areas with luminescent solar concentrators: geometry effects

Subjects: subject: Applied Physics (physics.app-ph)

description: Luminescence solar concentrators act as semi-transparent photovoltaic cells and can be applied to large surface areas in modern urban environment. In this paper their optical efficiencies were analytically derived for different unit shapes as simple, integral-free expressions. Perimeter length increase for the same enclosed area requires more photodetectors, yet reduces optical losses per unit. An exact interplay between these two parameters is presented, which can be directly applied to the analysis of tiling for large areas. An explicit expression for the critical size of an LSC unit, above which its inner part becomes inactive, has been obtained. Fabrication of devices larger than specified by this limit should be discouraged from efficiency considerations.

title: The relationships that bind? Power and alter-globalisation networks
Creators: name: Gabay, Clive
Publisher: name: The Open University
Year: 2010

description: Many scholars celebrate the emancipatory potential of alter-globalisation networks. This thesis tests this claim, using a case study of the Global Call to Action against Poverty (GCAP), and analysing what the powers which constitute this network reveal about the powers of it. GCAP is one of the largest networks of its type, mobilising nearly 175 million people on a single day in 2009 via national coalitions of civil society organisations in 115 countries. The PhD research focuses on two of these national coalitions in India and Malawi, as well as GCAP's broad governance structures, and utilises semi-structured and ethnographic interviews, participant observation and documentary analysis. The data was analysed through a methodological frame of governmentality and post-governmentality literatures, to analyse the full range of discourses and agencies which construct GCAP. The thesis interrogates the agency of GCAP through an exploration of three power-related themes, namely: the relationships GCAP enacts with processes of statist and neo-liberal hegemony; how GCAP develops relations of solidarity across distance; and the manner in which GCAP constructs subjects of legitimation. The thesis finds that GCAP embodies a monitored subjectivity vis-A-vis statist and neo-liberal hegemonic power, yet also retains a monitory agency on those powers. It furthermore finds that relations of solidarity developed in GCAP between areas of structural advantage and disadvantage are imbued with both colonial and postcolonial discourses, which simultaneously buttress and contest neoliberal discourses of managerialism, resource-dependency and the fetishisation of 'the poor'. These different sets of relations construct GCAP with a contingent, contradictory, yet at times emancipatory and transcendent subjectivity. By creating a snapshot of an alter-globalisation network in diverse social contexts, this thesis reveals the ways in which the power of such networks is uneven and immanent, dependent upon confluences of the various internal and external powers which constitute them.

description: Counting statistics of charge transfers in a point contact interacting with an arbitrary quantum system is studied. The theory for the charge specific density matrix is developed, allowing the evaluation of the probability of the outcome of any joint measurement of the state of the quantum system and the transferred charge. Applying the method of charge projectors, the master equation for the charge specific density matrix is derived in the tunneling Hamiltonian model of the point contact. As an example, the theory is applied to a quantum measurement of a two-state system: The evolution of the charge specific density matrix in the presence of Nyquist or Schottky noise is studied and the conditions for the realization of a projective measurement are established.

description: The effect of commute time on labor supply is estimated in a unique labor market in which workers are subject to daily exogenous variation in commute time and are free to make daily labor supply decisions: substitute teaching. Data on both accepted and rejected job offers received by substitute teachers are used to estimate a sequential binary-choice model of job-offer acceptance decisions. The elasticity of the offer-acceptance probability with respect to commute time is found to be about -0.4. The aversion to commuting is about 36% larger on extremely cold mornings, but precipitation has essentially zero impact on commuting preferences. The effect of fuel price is of the expected sign, but imprecisely estimated. Women are particularly averse to commuting on cold mornings and are more sensitive to variation in fuel prices than men, but no statistically significant difference in the overall aversion to commuting is found between men and women.

description: Agricultural transformation has been slow in Nigeria despite relatively fast growth in the non-agricultural sector of the economy. The limited contributions of irrigation in the agricultural sector have been considered to be one of the causes of slow agricultural transformation in Nigeria. Irrigation is used in both public-sector and private-sector irrigation schemes. Information is, however, often limited regarding small-scale private irrigation systems and their expansion potential and constraints, as compared to information on public irrigation schemes. This paper aims to provide various qualitative indicators which can shed light on irrigation system diversity and its recent evolution in Nigeria, as well as key economic characteristics of a selected private irrigation system as a case study.

description: The electronic nematic phase occurs when the point-group symmetry of the lattice structure is broken, due to electron-electron interactions. We study a model for the nematic phase on a square lattice with emphasis on the phase transition between isotropic and nematic phases within mean field theory. We find the transition to be first order, with dramatic changes in the Fermi surface topology accompanying the transition. Furthermore, we study the conductivity tensor and Hall constant as probes of the nematic phase and its transition. The relevance of our findings to Hall resistivity experiments in the high-$T_c$ cuprates is discussed.

title: Problem Oriented Engineering for Software Safety
Creators: name: Mannering, Derek Paul
Publisher: name: The Open University
Year: 2010

description: Safety critical systems must satisfy stringent safety standards and there development requires the use of specialist safe software system development (SSSD) approaches as the complexity and penetration of these systems increases. These SSSD approaches satisfy certain useful properties that make them suitable for safety system development. The first objective of this thesis is to select a candidate SSSD approach and evaluate its capabilities against a set of useful properties identified from reviewing a group of existing SSSD approaches, and thus show that this candidate SSSD approach is appropriate for use in safety system development. In addition, a second objective is to use this candidate SSSD approach to improve the early life cycle phase of an existing industrial safety development process used to develop embedded avionics applications. In particular to allow issues to be resolved earlier in the development, which are currently not being uncovered until much later in the development when they are much more difficult and expensive to correct. This involved the identification of further properties and issues that the candidate SSSD approach must address. The overall aim is to demonstrate that this candidate SSSD approach can be used in the early phase of a safety system development to derive a validated specification that can be subjected to safety analysis to show that it satisfies the identified system safety properties and thus forms a viable basis for the rest of the development.

description: The problem of mean square optimal estimation of linear functionals which depend on the unobserved values of a periodically correlated stochastic sequence is considered. The estimates are based on observations of the sequence with a noise. Formulas for calculation the mean square errors and the spectral characteristics of the optimal estimates of functionals are derived in the case of spectral certainty, where the spectral densities of the sequences are exactly known. Formulas that determine the least favorable spectral densities and the minimax spectral characteristics are proposed in the case of spectral uncertainty, where the spectral densities of the sequences are not exactly known while some classes of admissible spectral densities are specified.

description: Angle-resolved photoemission (PE) was used to characterize the spin-density wave (SDW) state in thin films of Cr grown on W(110). The PE data were analysed using results of local spin density approximation layer-Korringa-Kohn-Rostoker calculations. It is shown that the incommensurate SDW can be monitored and important parameters of SDW-related interactions, such as coupling strength and energy of collective magnetic excitations, can be determined from the dispersion of the renormalized electronic bands close to the Fermi energy. The developed approach can readily be applied to other SDW systems including magnetic multilayer structures.

description: This paper presents a reflection over a public policy experience denominated Pacto São Chico – Produtos Jeito Caseiro, designed to create job opportunities and income for family farmers based on agroindustrialization and on the construction of short marketing circuits in the municipality of São Francisco de Assis (SFA), Rio Grande do Sul, Brazil. The objective of this article is to discuss the categories which enable the formation of a SYAL based on the Pacto São Chico – Produtos Jeito Caseiro program. To do this, we conducted a predominantly qualitative research, with exploratory-descriptive character. The results show the unleashing of a series of synergistic effects that can configure complementarity between public policies and the establishment of a legal, institutional and policy framework, capable of enhancing resources and initiatives for the territory. With this experience, the results structured the SYAL, especially by qualifying sociocultural ties between farmers and consumers, as well as strengthening an identity surrounding the territory and a diversity of products, configured as a short circuit. The Pacto São Chico – Produtos Jeito Caseiro program has the potential to reveal a repaired action proposal and, with the due adjustments, is likely to be used in other settings.

description: We analyze the role of hedge fund, swap dealer and arbitrageur activity in a Markov regime-switching model between high volatility bear markets and low volatility bull markets for crude oil, corn and Mini-S&P500 index futures. We find that these institutional positions reflect fundamental economic factors within each market. More importantly, institutional positions also contribute incrementally to the probability of regime changes displaying the synchronization patterns modeled in Abreu and Brunnermeier (2002; 2003). Conditioning on hedge fund activity and arbitrageur activity significantly improves our probability estimates, demonstrating that institutional positions can be useful in determining whether price trends resembling bubble patterns will continue or reverse.

description: There is significant current interest in spintronic devices fashioned after a spin analog of the electro-optic modulator proposed by Datta and Das [Appl. Phys. Lett., \underline{56}, 665 (1990)]. In their modulator, the ``modulation'' of the spin polarized current is carried out by tuning the Rashba spin-orbit interaction with a gate voltage. Here, we propose an analogous modulator where the modulation is carried out by tuning the Dresselhaus spin orbit interaction instead. The advantage of the latter is that there is no magnetic field in the channel unlike in the case of the Datta-Das device. This can considerably enhance modulator performance.

subject: FOS: Computer and information sciences

description: Drawing inference from data is an important skill for students to understand their everyday life, so that the sampling distribution as a central topic in statistical inference is necessary to be learned by the students. However, little is known about how to teach the topic for high school students, especially in Indonesian context. Therefore, the present study provides a teaching experiment to support the students' informal inferential reasoning in understanding the sampling distribution, as well as the students' perceptions toward the teaching experiment. The subjects in the present study were three 11th-grader of one private school in Yogyakarta majoring in mathematics and natural science. The method of data collection was direct observation of sampling distribution learning process, interviews, and documentation. The present study found that that informal inferential reasoning with problem-based learning using contextual problems and real data could support the students to understand the sampling distribution, and they also gave positive responses about their learning experience.

description: The purpose of this study was to discuss the importance of federal public policies focused on the promotion of differentiated mesorregions development process in a new configuration of rural space, especially the case of the mesorregion Great Frontier of Mercosur (Mesomercosul). The State’s role, however, is to regulate and promote development public policies such as those addressing agricultural sector, particularly the family farming. A descriptive case study was adopted. Database of projects developed from the year of 2001 to 2006 was used as sources of data for documentary and journalistic surveys. In addition, information was obtained by means of statistically and field data collection. The bibliographical, documentary and quantitativeresearch techniques were used Results indicate that the consolidation of the Mesomercosul enables to elevate regional autonomy, allowing alternatives that promote sustainability by means of organization of public power and civil society. In addition, results contribute to the development process of spaces both essentially as relatively rural, enabling the consolidation of development alternatives in long term.

description: The objective of this study was to analyze the efficiency of a sample of organizations participating in the Agricultural Cooperatives Capitalization Program (PROCAP-AGRO), government program instituted with the objective of promoting the restructuring of the patrimony of individual and central cooperatives exclusively acting in agricultural, livestock, agroindustry, aquaculture or fishery production. The study was based on the conceptual foundations of property rights and financial constraints in cooperative organizations, considering a sample of forty production units spread throughout the Brazilian territory, and divided into two groups. The efficiency was measured by means of the data envelopment analysis, observing variations in the technical efficiency of the cooperatives, comparing them before and after the obtaining of resources. By using the econometric model of censored samples (Tobit), we investigated whether the PROCAP-AGRO was linked to the variations in efficiency of these organizations. The results indicate improvements after instituting PROCAP-AGRO, with distinct effects over the technical efficiency of the cooperatives as a result of the diverse use of program resources. We concluded that adjustments in the program are necessary for a better use of the resources obtained by the cooperatives.
