Career Outcomes for Formerly Incarcerated College Graduates

The California State University (CSU) Project Rebound is a reentry program that provides educational, social, financial, and case management to formerly incarcerated college students (FICS) with the goal of helping them become successful post-incarceration and post-graduation. However, there is a penury of research on how Project Rebound actually helped FICS create pro-social bonds and develop career preparation competencies. This exploratory study is an attempt to fill this gap in the literature by looking at the outcomes of formerly incarcerated college graduates who participated in a CSU-sponsored reentry program. In this qualitative study, semi-structured interviews were conducted with 13 alumni of a specific Project Rebound program (N = 13). Results from thematic analysis revealed five major themes. First, there is a broad range of support that constitutes the career-building network of formerly incarcerated college students. Second, respondents report a ‘mixed bag’ in terms of career seeking experiences post-graduation. Third, despite progress, a lot remains to be seen in terms of reintegrating formerly incarcerated college graduates into the workplace. Fourth, deficiencies exist within the broad range of support necessary for increased career outcomes. Fifth, graduates who were proactive in regard to career building strategies reported more positive career seeking experiences and increased job satisfaction. Implications of the findings for theory, research, social work practice, and policy are discussed. Keywords: FICGs, reentry programs, Project Rebound, employment, qualitative data

The Band Excitation Method in Scanning Probe Microscopy for Rapid Mapping of Energy Dissipation on the Nanoscale

Mapping energy transformation pathways and dissipation on the nanoscale and understanding the role of local structure on dissipative behavior is a challenge for imaging in areas ranging from electronics and information technologies to efficient energy production. Here we develop a novel Scanning Probe Microscopy (SPM) technique in which the cantilever is excited and the response is recorded over a band of frequencies simultaneously rather than at a single frequency as in conventional SPMs. This band excitation (BE) SPM allows very rapid acquisition of the full frequency response at each point (i.e. transfer function) in an image and in particular enables the direct measurement of energy dissipation through the determination of the Q-factor of the cantilever-sample system. The BE method is demonstrated for force-distance and voltage spectroscopies and for magnetic dissipation imaging with sensitivity close to the thermomechanical limit. The applicability of BE for various SPMs is analyzed, and the method is expected to be universally applicable to all ambient and liquid SPMs.Comment: 32 pages, 9 figures, accepted for publication in Nanotechnolog

Inverse design of plasma metamaterial devices with realistic elements

In an expansion of a previous study [1], we apply inverse design methods to produce two-dimensional plasma metamaterial devices with realistic plasma elements which incorporate quartz envelopes, collisionality (loss), non-uniform density profiles, and resistance to experimental error/perturbation. Backpropagated finite difference frequency domain simulations are used to design waveguides and demultiplexers operating under the transverse magnetic polarization. Optimal devices with realistic elements are compared to previous devices with idealized elements, and several parameter initialization schemes for the optimization algorithm are explored. Demultiplexing and waveguiding are demonstrated for microwave-regime devices composed of plasma elements with reasonable space-averaged plasma frequencies ~10 GHz and a collision frequency ~1 GHz, allowing for future in-situ training and experimental realization of these designs.Comment: 9 pages, 9 figure

Inverse design and experimental realization of plasma metamaterials

We apply inverse design methods to produce two-dimensional triangular-lattice plasma metamaterial (PMM) devices which are then constructed and demonstrated experimentally. Finite difference frequency domain simulations are used along with forward-mode automatic differentiation to optimize the plasma densities of each of the plasma elements in the PMM to perform beam steering and demultiplexing under transverse magnetic polarization. The optimal device parameters are then used to assign plasma density values to elements that make up an experimental version of the device. Device performance is evaluated against both the simulated results and human-designed alternatives, showing the benefits and disadvantages of in-silico inverse design and paving the way for future fully in-situ optimization.Comment: 22 pages, 8 figures; submitted to Phys.

Electromechanical Imaging of Biological Systems with Sub-10 nm Resolution

Electromechanical imaging of tooth dentin and enamel has been performed with sub-10 nm resolution using piezoresponse force microscopy. Characteristic piezoelectric domain size and local protein fiber ordering in dentin have been determined. The shape of a single collagen fibril in enamel is visualized in real space and local hysteresis loops are measured. Because of the ubiquitous presence of piezoelectricity in biological systems, this approach is expected to find broad application in high-resolution studies of a wide range of biomaterials.Comment: 12 pages, 4 figures, submitted for publication in Appl.

Direct Measurement of Periodic Electric Forces in Liquids

The electric forces acting on an atomic force microscope tip in solution have been measured using a microelectrochemical cell formed by two periodically biased electrodes. The forces were measured as a function of lift height and bias amplitude and frequency, providing insight into electrostatic interactions in liquids. Real-space mapping of the vertical and lateral components of electrostatic forces acting on the tip from the deflection and torsion of the cantilever is demonstrated. This method enables direct probing of electrostatic and convective forces involved in electrophoretic and dielectroforetic self-assembly and electrical tweezer operation in liquid environments

Probing the role of single defects on the thermodynamics of electric-field induced phase transitions

The kinetics and thermodynamics of first order transitions is universally controlled by defects that act as nucleation sites and pinning centers. Here we demonstrate that defect-domain interactions during polarization reversal processes in ferroelectric materials result in a pronounced fine structure in electromechanical hysteresis loops. Spatially-resolved imaging of a single defect center in multiferroic BiFeO3 thin film is achieved, and the defect size and built-in field are determined self-consistently from the single-point spectroscopic measurements and spatially-resolved images. This methodology is universal and can be applied to other reversible bias-induced transitions including electrochemical reactions.Comment: 34 pages,4 figures, high quality figures are available upon request, submitted to Phys.

Trajetos de Rogério (s) : escrevivências de um estudante periférico que na descortina-ação da cidade (se) encontra com a população em situação de rua

Este trabalho visa descortinar Porto Alegre e a Psicologia dos seus pré-conceitos estabelecidos que constroem regimes de saber/poder estereotipantes da periferia e da População em Situação de Rua. Para tanto, a partir de uma escrita ficcional baseada nas trajetórias de Rogério, um personagem criado para protagonizar as experiências coletivas de um homem cis, pardo e periférico desta cidade; constroem-se narrativas de dentro para fora sobre a periferia e criticamse as Psicologias hegemônicas eurocentradas, normativas e que se dizem universais, procurando desenvolver Psicologias contra-hegemônicas, Periféricas e Decoloniais
