Shifting From Social Service to Social Change

Publisher: name: Columbia Social Work Review
Year: 2019

description: Casa de Esperanza (Casa) is an influential domestic violence organization in St. Paul, Minnesota. Upon examining the changes that have occurred within the organization since its inception, we have struggled with returning to the original mission of addressing domestic violence only in the Latino/a community or remaining an agency that serves women from diverse backgrounds. Casa has decided to remain an organization dedicated to serving women from diverse backgrounds, but will now place the community, rather than the individual, at the center of the organization. Within the next ten years, Casa will shift from providing direct social services to working toward broader social change. Specific changes include phasing out direct services, mobilizing communities to fight violence against women as it intersects with other forms of violence, and advocating for legislative change.

description: The moving-contact line between a fluid, liquid and a solid is a ubiquitous phenomenon, and determining the maximum speed at which a liquid can wet/dewet a solid is a practically important problem. Using continuum models, previous studies have shown that the maximum speed of wetting/dewetting can be found by calculating steady solutions of the governing equations and locating the critical capillary number, $Ca_{\mathrm{crit}}$, above which no steady-state solution can be found. Below $Ca_{\mathrm{crit}}$, both stable and unstable steady-state solutions exist and if some appropriate measure of these solutions is plotted against $Ca$, a fold bifurcation appears where the stable and unstable branches meet. Interestingly, the significance of this bifurcation structure to the transient dynamics has yet to be explored. This article develops a computational model and uses ideas from dynamical systems theory to show the profound importance of the unstable solutions on the transient behaviour. By perturbing the stable state by the eigenmodes calculated from a linear stability analysis it is shown that the unstable branch is responsible for the eventual dynamical outcomes and that the system can become unstable when $CaCa_{\mathrm{crit}}$, we will show that the trajectories in phase space closely follow the unstable branch.

description: We solve the Laplace equation $\Box h_{ij}=0$ describing the propagation of gravitational waves in an expanding background metric with a power law scale factor in the presence of a point mass in the weak field approximation (Newtonian McVittie background). We use boundary conditions at large distances from the mass corresponding to a standing spherical gravitational wave in an expanding background which is equivalent to a linear combination of an incoming and an outgoing propagating gravitational wave. We compare the solution with the corresponding solution in the absence of the point mass and show that the point mass increases the amplitude of the wave and also decreases its frequency (as observed by an observer at infinity) in accordance with gravitational time delay.

description: Private nonprofits are increasingly relied upon to provide social services in the United States. As these nonprofits professionalize and look to the government and foundations to fund their work, communities may be deprived of services they need in order for the agendas of funders to be carried out. By examining the rise of the nonprofit as an institution in the United States, this article examines how social justice has been separated from social service provision by the system that has come to be known as the Nonprofit Industrial Complex.

description: The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their own fisheries. One of the key uncertainties in fisheries science and management can be linked to (our understanding of) fishers behaviour. In this report we describe the project efforts to better understand fishers behaviour by assessing literature, interviews and data to advance towards a better representation of fisher behaviour in our modelling. A better understanding of fisher behaviour is especially needed in the context of change affecting Europe’s marine ecosystems. Change is both related to the natural part of the ecosystem (i.e. climate change) as to the social side of the ecosystem (i.e. building of windparks). To that aim we present nine different case studies in Europe as examples of how fisher behaviour has been studied and which factors are (or can be) relevant for a better understanding of fisher behaviour. Each case study ends with a table summarising the factors influencing behaviour, the categories within that factor and the (potential) application in modelling as well as the implications for management. The table below summarises the factors found / used in the case studies and the elements (social, cultural, ecological, economic and institutional) to which the relate. A variety of social factors were identified that are promising for use in modelling. A key conclusion is that social data are often context dependant and cannot be copy pasted from one situation to the other and in some case, additional data needs to be collected. The cases also demonstrate that mixed methods approaches and interdisciplinary approaches are key to get in-depth of understanding of fisher behaviour in fisheries science.

description: This article proposes an approach to estimate and make inference on the parameters of copula link-based survival models. The methodology allows for the margins to be specified using flexible parametric formulations for time-to-event data, the baseline survival functions to be modeled using monotonic splines, and each parameter of the assumed joint survival distribution to depend on an additive predictor incorporating several types of covariate effects. All the model’s coefficients as well as the smoothing parameters associated with the relevant components in the additive predictors are estimated using a carefully structured efficient and stable penalized likelihood algorithm. Some theoretical properties are also discussed. The proposed modeling framework is evaluated in a simulation study and illustrated using a real dataset. The relevant numerical computations can be easily carried out using the freely available GJRM R package. Supplementary materials for this article are available online.
Utilizing Exercise and Nutrition in the Treatment of Chronic Disease
Creators: name: Kim, Jake T.
Publisher: name: Columbia Social Work Review
Year: 2019

description: The prevalence of chronic diseases in America has increased substantially within the last few decades, increasing the cost of healthcare by billions of dollars. In addition, these diseases have a higher incidence rate for low-income populations who may have greater difficulty accessing adequate resources or appropriate treatments. There has been a growing body of literature supporting the use of community-based exercise and nutrition interventions. Community-based interventions emphasize social supports and personal empowerment for behavioral change. Given the chronic and growing nature of these diseases, this paper will examine community-based exercises and the surrounding elements which facilitate and hinder behavioral change.

description: In their paper titled "Deep Models of Superficial Face Judgments" [1], Joshua C. Peterson et al. employ Nvidia’s StyleGAN technology to manipulate facial images based on surfacelevel attributes such as attractiveness or age. They conducted an exhaustive investigation to capture these attributes. More than 1000 synthetic facial images were generated, accompanied by over a million human judgments across 34 attributes. The resultant model has the capability to produce facial images that evoke specific impressions aligned with the modeled attributes. Both the evaluated images and the corresponding judgments have been publicly shared. Leveraging this dataset, we have developed our own customisable face generation model. Our model is publically available on Github

description: A majority of studied models for scale-free networks have degree distributions with exponents greater than $2$. Real networks, however, can demonstrate essentially more heavy-tailed degree distributions. We explore two models of scale-free equilibrium networks that have the degree distribution exponent $γ= 1$, $P(q) \sim q^{-γ}$. Such degree distributions can be identified in empirical data only if the mean degree of a network is sufficiently high. Our models exploit a rewiring mechanism. They are local in the sense that no knowledge of the network structure, apart from the immediate neighbourhood of the vertices, is required. These models generate uncorrelated networks in the infinite size limit, where they are solved explicitly. We investigate finite size effects by the use of simulations. We find that both models exhibit disassortative degree-degree correlations for finite network sizes. In addition, we observe a markedly degree-dependent clustering in the finite networks. We indicate a real-world network with a similar degree distribution.

description: High-energy photons with $\mathcal{O}$(MeV) energies from radioactive contaminants can scatter in a solid-state target material and constitute an important low-energy background for sub-GeV dark matter direct-detection searches. This background is most noticeable for energy deposits in the $1 - 100$ meV range due to the partially coherent scattering enhancement in the forward scattering direction. We comprehensively quantify the resulting single- and multi-phonon background in Si, Ge, GaAs, SiC, and Al$_2$O$_3$ target materials, which are representative of target materials of interest in low-mass dark matter searches. We use a realistic representation of the high-energy photon background, and contrast the expected background phonon spectrum with the expected dark matter signal phonon spectrum. An active veto is needed to suppress this background sufficiently in order to allow for the detection of a dark matter signal, even in well-shielded environments. For comparison we also show the expected single- and multi-phonon event rates from coherent neutrino-nucleus scattering due to solar neutrinos, and find that they are sub-dominant to the photon-induced phonon background.

description: Locomotion by shape changes (spermatozoon swimming, snake slithering, bird flapping) or gas expulsion (rocket firing) is assumed to require environmental interaction, due to conservation of momentum. As first noted in (Wisdom, 2003) and later in (Guéron, 2009) and (Avron et al, 2006), in curved space or spacetime the non-commutativity of translations permits translation without momentum exchange, just as falling cats and lizards can self-deform to reorient in flat space without environmental interaction. Translation in curved space can occur not only in gravitationally induced curved spacetime (where translation is predicted to be on the order of $10^{-23}$ m per gait cycle) but also in the curved surfaces encountered by locomotors in real-world environments. Here we show that a precision robophysical apparatus consisting of motors driven on curved tracks (and thereby confined to a spherical surface without a solid substrate) can self-propel without environmental momentum exchange (impulse) via shape changes that can generate gauge potentials that manifest as translations. Our system produces shape changes comparable to the environment's inverse curvatures and generates from zero momentum forward movement of $10^{-1}$ cm per gait cycle even while resisted by weak gravitational and frictional forces. Dissipation via friction eventually arrests the robot but also imbues it with momentum which can be released upon a cessation of shape changes. This work demonstrates how the interaction between environmental curvature, active driving and geometric phases yields rich, exotic phenomena.

description: Mental health courts (MHCs) are emerging as a critical element in the nationwide effort to counter overcrowding in the US prison system and more adequately address the plight of offenders who are diagnosed with a mental illness. The goals of MHCs, an example of problem-solving courts, are to improve the quality of life for those involved in the criminal justice system, link clients to community treatment resources, and reduce recidivism and crime rates in a more cost-effective manner than within the traditional criminal justice process. This article provides a brief history of MHCs, including the rationale behind their initial implementation, an overview of their clientele and process, a review of the role social workers play, arguments for and against their broader introduction, and specific research recommendations to better ascertain their current and future effectiveness. Although MHCs are still too nascent to draw broad conclusions about their rates of efficacy, early results are promising.

description: We have observed the three-photon correlation in nonclassical light sources by using an indirect measurement scheme based on the dead time effect of photon-counting detectors. We first developed a general theory which enables us to extract the three-photon correlation from the two-photon correlation of an arbitrary light source measured with detectors with finite dead times. We then confirmed the validity of our measurement scheme in experiments done with the cavity-QED microlaser operating with a large intra-cavity mean photon number exhibiting both sub- and super-poissoniaq photon statistics. The experimental results were in a good agreement with the theoretical expectation. Our measurement scheme provides an alternative approach for N-photon correlation measurement employing (N-1) detectors and thus a reduced measurement time for a given signal-to-noise ratio, compared to the usual scheme requiring N detectors.

description: As a mecca of diversity, New York City is one of the epicenters for the lesbian, gay, bisexual, and transgender LGBT community. As such, LGBT identified clients present in New York’s counseling and mental health agencies with a cross section of issues unique to the LGBT community. One of these issues is the deleterious effects LGBT-individuals face after an experience with conversion therapy. Conversion therapy aims to alter a person’s sexual orientation away from homosexuality and into heterosexuality or celibacy. Clients seeking counseling after an experience with conversion therapy present distinct practice challenges that require special consideration in treatment. These clients may experience both sexual and spiritual identity crises, symptoms of depression and anxiety, hopelessness, sexual dysfunction, and symptoms of post-traumatic stress. Integrative solution therapies, grief work, community-based interventions, and trauma work offer healing strategies for treating LGBT clients after conversion therapy.

Bitumen recovery from oil sands in northeastern Alberta, Canada produces large volumes of tailings, which are deposited in mining areas that must be reclaimed upon mine closure. A new technology of non-segregated tailings (NST) developed by Canadian Natural Resources Limited (CNRL) was designed to accelerate the process of oil sands fine tailings consolidation. However, effects of these novel tailings on plants used for the reclamation of oil sands mining areas remain to be determined. In the present study, we investigated the effects of NST on seedlings of three species of plants commonly planted in oil sands reclamation sites including paper birch (Betula papyrifera), white spruce (Picea glauca) and green alder (Alnus viridis). In the controlled-environment study, we grew seedlings directly in NST and in the two types of reclamation soils with and without added NST and we measured seedling growth, gas exchange parameters, as well as tissue concentrations of selected elements and foliar chlorophyll. White spruce seedlings suffered from severe mortality when grown directly in NST and their needles contained high concentrations of Na. The growth and physiological processes were also inhibited by NST in green alder and paper birch. However, the addition of top soil and peat mineral soil mix to NST significantly improved the growth of plants, possibly due to a more balanced nutrient uptake. It appears that NST may offer some advantages in terms of site revegetation compared with the traditional oil sands tailings that were used in the past. The results also suggest that, white spruce may be less suitable for planting at reclamation sites containing NST compared with the two studied deciduous tree species.

Attrition Risk and Resilience Among Sexual Minority College Students
Creators: name: Mancini, Olivia
Publisher: name: Columbia Social Work Review
Year: 2019

description: Retention is one of the most frequently studied issues regarding college students. Most of this research has focused on majority college students, e.g., White, middle-class. More recently, retention literature has expanded to look at reasons why minority (e.g., non-White, disabled) college students decide to stay at or leave a university. Lesbian, gay, bisexual, and transgender (LGBT) students, however, remain an under-acknowledged and little-studied group in retention literature. This article seeks to demonstrate how sexual minority students are at high risk of attrition and why this group deserves research devoted to reducing this risk. This article also discusses how changes to college policy can improve the campus climate and quality of life for LGBT students.

description: Recent observational progress has led to the establishment of the standard $Λ$CDM model for cosmology. This development is based on different cosmological probes that are usually combined through their likelihoods at the latest stage in the analysis. We implement here an integrated scheme for cosmological probes, which are combined in a common framework starting at the map level. This treatment is necessary as the probes are generally derived from overlapping maps and are thus not independent. It also allows for a thorough test of the cosmological model and of systematics through the consistency of different physical tracers. As a first application, we combine current measurements of the Cosmic Microwave Background (CMB) from the Planck satellite, and galaxy clustering and weak lensing from SDSS. We consider the spherical harmonic power spectra of these probes including all six auto- and cross-correlations along with the associated full Gaussian covariance matrix. This provides an integrated treatment of different analyses usually performed separately including CMB anisotropies, cosmic shear, galaxy clustering, galaxy-galaxy lensing and the Integrated Sachs-Wolfe (ISW) effect with galaxy and shear tracers. We derive constraints on $Λ$CDM parameters that are compatible with existing constraints and highlight tensions between data sets, which become apparent in this integrated treatment. We discuss how this approach provides a complete and powerful integrated framework for probe combination and how it can be extended to include other tracers in the context of current and future wide field cosmological surveys.

description: Detecting magnetic order at the nanoscale is of central interest for the study of quantum magnetism in general, and the emerging field of moiré magnets in particular. Here, we analyze the exciton band structure that arises from a periodic modulation of the valley Zeeman effect. Despite long-range electron-hole exchange interactions, we find a sizable splitting in the energy of the bright circularly-polarized exciton Umklapp resonances, which serves as a direct optical probe of magnetic order. We first analyze quantum moiré magnets realized by periodic ordering of electron spins in Mott-Wigner states of transition metal dichalcogenide (TMD) monolayers or twisted bilayers: we show that spin-valley dependent exciton-electron interactions allow for probing the spin-valley order of electrons and demonstrate that it is possible to observe unique signatures of ferromagnetic order in a triangular lattice and both ferromagnetic and Néel order in a honeycomb lattice. We then focus on semiclassical moiré magnets realized in twisted bilayers of ferromagnetic materials: we propose a detection scheme for moiré magnetism which is based on inter-layer exchange coupling between spins in a moiré magnet and excitons in a TMD monolayer.

description: We propose a novel Riemannian geometric framework for variational inference in Bayesian models based on the nonparametric Fisher–Rao metric on the manifold of probability density functions. Under the square-root density representation, the manifold can be identified with the positive orthant of the unit hypersphereS∞inL2, and the Fisher–Rao metric reduces to the standardL2metric. Exploiting such a Riemannian structure, we formulate the task of approximating the posterior distribution as a variational problem on the hypersphere based on the α-divergence. This provides a tighter lower bound on the marginal distribution when compared to, and a corresponding upper bound unavailable with, approaches based on the Kullback–Leibler divergence. We propose a novel gradient-based algorithm for the variational problem based on Fréchet derivative operators motivated by the geometry ofS∞, and examine its properties. Through simulations and real data applications, we demonstrate the utility of the proposed geometric framework and algorithm on several Bayesian models.

description: Alarmist messages surrounding the obesity epidemic have influenced many in the social justice community to adopt a combative stance against the purported “fat explosion.” However, by aligning itself with the corporate interests, biased research, and buried prejudices driving the nation’s fear of fat, the social justice community is distancing itself from its original purpose and unwittingly perpetuating a hostile and antagonistic environment for fat people. This paper will serve as a critique of the mainly uncontested obesity narrative and provide justification for why social workers should frame weight-based discrimination as an issue of social justice.

Here, we consider the computational task of determining whether or not a given table of possibilities constitutes a departure from possibilistic local realism. By considering the case in which one party has access to measurements with two outcomes and the other three, it is possible to see at exactly which point this task becomes computationally difficult.

description: Energy dependence of specific heat extracted from temperature fluctuation of Au + Au collisions at $\sqrt{s_{NN}}$ = 7.7 GeV to 200 GeV was investigated by using a multiphase transport (AMPT) model. The results were compared with those from other models and some differences at low $\sqrt{s_{NN}}$ were found. To explain the above differences and describe the properties of the hot dense matter at low $\sqrt{s_{NN}}$, a new quantity $C_v^{*}$ was derived for describing specific heat in heavy-ion collisions. It was found that, by using $C_v^{*}$ together with its high order moments (skewness and kurtosis), thermal properties of the hot dense matter can be described and different thermal properties with or without parton process can be clearly distinguished. The proposed observable provides a way to learn the property of QCD matter % phase transition %along with critical point in heavy-ion collisions.

description: When studying natural disasters, it is necessary to analyze the circumstances with a comprehensive approach that focuses on relief and moving the affected area from development to sustainability. Thus, it is imperative to consider all social, environmental, and psychological factors when addressing the complex needs of disaster response from a social work perspective. To establish immediate and long-term support networks, it is also necessary to bring together interdisciplinary teams to assist in disaster relief efforts. In the past decade, a number of devastating natural disasters have managed to cause death, destruction, and disease within the populations of a vast number of countries. This paper examines global disaster relief efforts for three major natural disasters of the past decade through a review of the literature and from observations made in the field.

description: Angular-momentum or parity-dependent nonlocal optical potentials for nucleon-${}^{16}\mathrm{O}$ scattering able to fit differential cross section data over the whole angular regime are developed and applied to the description of deuteron-${}^{16}\mathrm{O}$ scattering in the framework of three-body Faddeev-type equations for transition operators. Differential cross sections and deuteron analyzing powers for elastic scattering and ${}^{16}\mathrm{O}(d,p){}^{17}\mathrm{O}$ transfer reactions are calculated using a number of local and nonlocal optical potentials and compared with experimental data. Angular-momentum or parity-dependence of the optical potential turns out to be quite irrelevant in the considered three-body reactions while nonlocality is essential for a successful description of the differential cross section data, especially in transfer reactions.

No Sure Cure for Elder Self-Neglect
Creators: name: Levin, Jeff
Publisher: name: Columbia Social Work Review
Year: 2019

description: Self-neglecting elders often ignore their own health needs and live unsafely in conditions of squalor. Their choice to live in isolation prevents intervention by loved ones, medical professionals, or agencies such as Adult Protective Services. This case study of a 76-year-old man details the many ways in which self-neglect can affect individuals and those around them. The ethical questions involved illustrate a social work dilemma of weighing an individual’s right to make lifestyle choices versus forcing one to adapt to society’s standards.

description: The increase in capacity provided by coupled SDM systems is fundamentally limited by MDG and ASE noise. Therefore, monitoring MDG and optical SNR is essential for accurate performance evaluation and troubleshooting. Recent works show that the conventional MDG estimation method based on the transfer matrix of MIMO equalizers optimizing the MMSE underestimates the actual value at low SNR. Besides, estimating the optical SNR itself is not a trivial task in SDM systems, as MDG strongly influences the electrical SNR after the equalizer. In a recent work we propose an MDG and SNR estimation method using ANN. The proposed ANN-based method processes features extracted at the receiver after DSP. In this paper, we discuss the ANN-based method in detail, and validate it in an experimental 73-km 3-mode transmission link with controlled MDG and SNR. After validation, we apply the method in a case study consisting of an experimental long-haul 6-mode link. The results show that the ANN estimates both MDG and SNR with high accuracy, outperforming conventional methods.

Psychosis Risk and Prevention of Persistent and Severe Mental Illness
Creators: name: DeVylder, Jordan
Publisher: name: Columbia Social Work Review
Year: 2019

description: The prognosis of schizophrenia and other psychotic disorders may be improved through efforts to identify at-risk individuals and to provide early interventions prior to the first episode of psychosis. Psychosis-risk syndrome is gaining recognition as a distinct clinical condition, and may be included as a diagnosis in the upcoming version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). As direct mental health practitioners, social workers are in an ideal position to both address the diverse psychosocial needs and improve the accessibility of services for this difficult-to-define population. As macro-level practitioners, social workers can provide a valuable perspective on ethical issues while advocating to reduce the stigma surrounding the provision of intensive mental health services to individuals struggling with psychosis-risk syndrome.

description: The field of gamma-ray astronomy has seen important progress during the last decade, yet there exists so far no common software framework for the scientific analysis of gamma-ray telescope data. We propose to fill this gap by means of the GammaLib software, a generic library that we have developed to support the analysis of gamma-ray event data. GammaLib has been written in C++ and all functionality is available in Python through an extension module. On top of this framework we have developed the ctools software package, a suite of software tools that enables building of flexible workflows for the analysis of Imaging Air Cherenkov Telescope event data. The ctools are inspired by science analysis software available for existing high-energy astronomy instruments, and they follow the modular ftools model developed by the High Energy Astrophysics Science Archive Research Center. The ctools have been written in Python and C++, and can be either used from the command line, via shell scripts, or directly from Python. In this paper we present the GammaLib and ctools software versions 1.0 that have been released end of 2015. GammaLib and ctools are ready for the science analysis of Imaging Air Cherenkov Telescope event data, and also support the analysis of Fermi-LAT data and the exploitation of the COMPTEL legacy data archive. We propose to use ctools as the Science Tools software for the Cherenkov Telescope Array Observatory.

Successful Community Reentry After Incarceration
Creators: name: Kiczkowski, Ursula Helene
Publisher: name: Columbia Social Work Review
Year: 2019

description: The United States prison population and rate of incarceration have climbed to the highest worldwide, and mass incarceration has become a concerning social issue. Research demonstrates that incarceration adversely affects social networks, increases risk factors for children of incarcerated parents, and economically and politically disenfranchises communities and neighborhoods. Through critical examination of the existing rubric of incarceration, reentry emerges as an integral point of intervention for social workers to disrupt the chronic cycle of recidivism and downward spiral caused by incarceration. While past research has provided a cursory knowledge of the risk and protective factors that predict reentry success, much remains obscure. The purpose of this qualitative study is to explore the intricate, recondite, and intimate ways that family members function to assist the formerly incarcerated individual during reentry. By analyzing data through a transactional social support paradigm, this paper expands upon and enhances existing literature on the implicit functions of familial social support during prisoner reentry. Implications for social work practice with formally incarcerated individuals are explored based on key findings from the study.
