Technology’s Role in the Nonprofit Sector
Creators: name: Boles, Brianna
Publisher: name: Columbia Social Work Review
Year: 2019

description: Increasing technology uptake in the nonprofit sector will allow nonprofit organizations and social workers to provide more effective services through improved work processes. The following paper will discuss how these processes (service delivery, fundraising, and outreach) are carried out in the nonprofit sector given the current technology landscape in nonprofits. I will provide background information about innovations such as cloud computing systems, social media, and mobile technologies that should be incorporated into the nonprofit sector in order to improve the quality of services and work processes. An overview of the barriers that nonprofits face, such as lack of knowledge, lack of resources, and demands by funders, will explain the challenges accompanying increased technology uptake. The final section provides a method to overcome obstacles, allowing the optimal integration of technology into the nonprofit sector.

Social Work Practice with Children Perinatally Infected with HIV
Creators: name: Nalls, Natasha K.
Publisher: name: Columbia Social Work Review
Year: 2019

description: The development of antiretroviral therapies (ARTs) has signifi cantly lengthened the lifespan and changed the life course of most individuals infected with HIV and AIDS in the United States. Furthermore, ART use during pregnancy has signifi cantly reduced the rate of mother-to-child (perinatal) HIV transmission. While perinatal infection rates among children in the United States have declined since the 1990s, ART regimens became standard treatment protocol, there remains a population of children entering adolescence who were born HIV-positive. This paper discusses: 1) the importance of diagnostic disclosure of HIV and AIDS status to infected children, 2) stigma and the disclosure process with children, and 3) the role of clinical social workers in facilitating the disclosure process.

The Role of Social Workers in the End-of-Life Debate
Creators: name: Zaleski, Jennifer
Publisher: name: Columbia Social Work Review
Year: 2019

description: Although many articles and books discuss the ethics of end-of-life issues, few publications are written specifi cally for social workers and social work students. The lack of relevant literature is problematic because social workers have different ethical obligations than other health care professions who work with clients who are contemplating assisted suicide. This paper will analyze the ethical dilemma that social workers face in end-of-life issues by reviewing the material available to social workers such as the NASW Code of Ethics and the relevant NASW Policy Statement. This paper fi nds that the different sources of information provided by NASW do not fully address the complexities surrounding the social work profession and end-of-life issues. Additional training and continuing education courses should be offered and a stronger policy statement is needed that explores the complexities faced by social workers in endof- life care.

description: Abstract Cultural heritage data are both inputs and outputs to the research process: they are the raw materials needed for a range of research activities in the arts, humanities and social sciences, and they are also often the outputs of those disciplinary fields, informing the interpretation and reuse of artefacts, objects, or records held by the institutions that shape and preserve cultural memory. Very few of these institutions consider their digital assets to be „data”, however, necessarily limiting the interoperability and potential value of these materials across a wide variety of scientific domains. As one of 11 case studies in the WorldFAIR Project, a major global collaboration led by CODATA and involving partners from thirteen countries across Africa, Australasia, Europe, and North and South America, the Cultural Heritage case study seeks to explore how image-sharing practices in memory institutions can be aligned more closely with the FAIR Principles for research data. This alignment aims to support wider reuse and harmonisation of cultural heritage images with digital resources produced by other domains, recognizing that interest in cultural heritage images may not be limited to researchers working from a cultural heritage perspective. This talk will explore the ‘FAIRness’ of current methodologies and practices in the cultural heritage sector that have been used to transform a wide variety of materials into digital assets, followed by an overview of the recommendations to be tested at the Digital Repository of Ireland to support the interoperability of cultural heritage data with resources in the larger digital research ecosystem. The outcomes of the DRI’s case study will contribute to the development of a cross-domain interoperability framework (CDIF) and recommendations for FAIR assessment produced by the WorldFAIR Project.
The Pledge Requirement

description: The human immunodefi ciency virus, which causes the acquired immunodefi ciency syndrome (HIV and AIDS), is a pandemic that militates against public health policy and practice on a global scale. The sex industry is frequently cited as one of the growth factors contributing to increased HIV and AIDS transmission, as well as the spread of sexually transmitted infections across international lines. Therefore, the prevention of HIV and AIDS among commercial sex workers is a major goal of the public health operations of both U.S. and foreign-based organizations working in the sex sector. As it stands, current U.S. laws and policies that dictate the funding of organizations working with sex workers are deleterious to public health and run counter to best practices that prevent the global spread of HIV and AIDS, as well as human rights norms. This article is centrally concerned with the public health implications of the Anti-Prostitution Pledge, which requires foreign NGOs and U.S.-based NGOs working abroad to explicitly oppose the practice of prostitution in order to receive U.S. federal funding for HIV and AIDS prevention among commercial sex workers. Policy prescriptions concerning the public health dimensions of commercial sex work will be offered based on the analysis.

description: Women with families are the most quickly increasing segment of the homeless population. Varying from state to state, between 22% and 85% of these homeless families report that they became homeless as a result of the choice to fl ee an abusive relationship. Domestic violence survivors are at risk of homelessness before entrance into the emergency shelter system, before gaining acceptance into the transitional shelter system, and once they have secured low-income housing. This problem has resulted in many domestic violence survivors choosing to remain with their children in violent homes as opposed to becoming homeless. Obstacles to help-seeking and limitations of emergency housing options are current issues resulting in homelessness among domestic violence survivors. Programmatic and policy recommendations are made to assist domestic violence survivors in obtaining and maintaining both long and short term housing.

description: In families affected by domestic violence, women are typically both the battered party and the parent most likely to be responsible for the caretaking of children. Although the domestic violence and child welfare service systems both work towards ending family violence, confl icting goals refl ect the historical tension between the woman-centered battered women’s movement and the child-centered child welfare system. This article considers the overlap between the domestic violence and child welfare service systems and women’s place at the intersection of these two spheres. Suggestions to improve policy and practice are made for social workers who serve battered women and children affected by family violence.

description: In this article, we describe and numerically implement a method for relativistic location in slightly curved but otherwise generic spacetimes. For terrestrial positioning in the context of Global Navigation Satellite Systems, our algorithm incorporates gravitational as well as tropospheric and ionospheric effects modeled by the Gordon metric. The algorithm is implemented in the \textsc{squirrel.jl} code, which employs a quasi-Newton Broyden algorithm in conjunction with automatic differentiation of numerical geodesics. Our work provides a practical solution to the relativistic location problem in a generic spacetime and consolidates relativistic and atmospheric effects in a single framework. Though optimization is not our primary focus, our implementation is already fast enough for practical use, establishing a position from five emission points in $< 1~{\rm s}$ on a desktop computer for reasonably simple spacetime geometries. In vacuum, our implementation can achieve submillimeter accuracy considering the Kerr metric with terrestrial parameters and submeter accuracy including tropospheric and ionospheric effects.

This hybrid construction offers a good compromise between stability and footprint on one side and means of intervention on the other. As experimentally verified by the absence of higher-order interferences, amplitude and phase can be manipulated in all paths independently. In conjunction with single photons, the setup can, therefore, be applied for fundamental investigations on quantum mechanics.

Latino Children's Mental Health
Creators: name: Holloway, Ian
Publisher: name: Columbia Social Work Review
Year: 2019

description: Research suggests that Latino children are at an elevated risk for a variety of mental health problems (Flores, Fuentes-Affl ick, Barbot, et al., 2002). Latinos are often vulnerable to the deleterious effects of poverty, institutional racism, community violence and other types of psychosocial stressors, which have been linked to negative mental health outcomes (Flisher, Kramer, Grosser, et al., 1997; Saunders, Resnick, Hoberman, et al., 1994). Furthermore, Latino children are likely to face signifi cant barriers to accessing mental healthcare services, such as limited availability of Spanish- speaking providers, diffi culty obtaining and navigating health insurance, and cultural obstacles, such as the belief that mental illness is a spiritual or religious matter. The current paper will: (1) explore specifi c risk factors for mental health disorders among Latino children; (2) examine barriers to appropriate mental health treatment among Latino children; (3) provide an overview of the types of intervention strategies currently used to address mental health problems among Latino children; and (4) offer recommendations for the development of additional and/or improved methods for the prevention and treatment of mental health disorders among Latino children.

description: Delensing is an increasingly important technique to reverse the gravitational lensing of the cosmic microwave background (CMB) and thus reveal primordial signals the lensing may obscure. We present a first demonstration of delensing on Planck temperature maps using the cosmic infrared background (CIB). Reversing the lensing deflections in Planck CMB temperature maps using a linear combination of the 545 and 857GHz maps as a lensing tracer, we find that the lensing effects in the temperature power spectrum are reduced in a manner consistent with theoretical expectations. In particular, the characteristic sharpening of the acoustic peaks of the temperature power spectrum resulting from successful delensing is detected at a significance of 16$\rmσ$, with an amplitude of $A_{\rm{delens}} = 1.12 \pm 0.07$ relative to the expected value of unity. This first demonstration on data of CIB delensing, and of delensing techniques in general, is significant because lensing removal will soon be essential for achieving high-precision constraints on inflationary B-mode polarization.

description: With the sample of observed tidal disruption events (TDEs) now reaching several tens, distinct spectroscopic classes have emerged: TDEs with only hydrogen lines (TDE-H), only helium lines (TDE-He), or hydrogen in combination with He II and often N III/O III (TDE-H+He). Here we model the light curves of 32 optically-bright TDEs using the Modular Open Source Fitter for Transients (MOSFiT) to estimate physical and orbital properties, and look for statistical differences between the spectroscopic classes. For all types, we find a shallow distribution of star masses, compared to a typical initial mass function, between $\sim 0.1-1$ M$_\odot$, and no TDEs with very deep ($β\gg 1$) encounters. Our main result is that TDE-H events appear to come from less complete disruptions (and possibly lower SMBH masses) than TDE-H+He, with TDE-He events fully disrupted. We also find that TDE-H events have more extended photospheres, in agreement with recent literature, and argue that this could be a consequence of differences in the self-intersection radii of the debris streams. Finally, we identify an approximately linear correlation between black hole mass and radiative efficiency. We suggest that TDE-H may be powered by collision-induced outflows at relatively large radii, while TDE-H+He could result from prompt accretion disks, formed more efficiently in closer encounters around more massive SMBHs.

description: In January 2006, students from CUSSW and Union Theological Seminary participated in an immersion course entitled, Katrina: Poverty, Race, and Social Work Practice. The aim of the course was to explore experientially the inequality exposed by Hurricane Katrina and its effect on some of the poorest communities and individuals in the United States. This paper presents an overview of the course development. In addition, the authors describe some of their experiences and observations before, during, and after their travels to the Gulf Coast and other communities affected by Hurricane Katrina. The specific focus of the article is on the themes of poverty, racism, violence, governmental irresponsibility and disregard in the wake of this tragedy, and describes some of the efforts made towards supporting social justice in the Gulf Coast as it rebuilds.

Generation of an optical Schrödinger-cat-like state in a non-ideal cavity by injecting opposite-phase atomic dipoles

description: We propose a method to generate an optical Schrödinger-cat-like state in a cavity in a substantial decoherence regime. Even when the cavity decay rate is considerably large, a cat-like state can be generated in a laser-like setting if the gain for the field is larger than the loss. Under the condition that opposite-phase atomic dipoles repeatedly traverse the cavity, the cavity field converges to a squeezed vacuum state in a steady state. A Schrödinger-cat-like state is then generated when a single photon decay occurs. The phase-space distribution of the cat state can be revealed in homodyne detection by using the decaying photon as a herald event. Quantum trajectory simulation was used to identify the conditions for the Schrödinger-cat-like state formation as well as to analyze the properties of those states. Based on these simulations, possible experiments are proposed within the reach of the current technology.

We begin by detailing the construction of the 1/4-BPS instanton solutions, their moduli space, and the moduli space potential using an explicit parametrisation of the moduli space coordinates in terms of the biquaternions. We then go on to numerically analyse the dynamics on the moduli spaces we have constructed, discussing some of the numerical issues which arose and describing the code we developed to solve them

description: Multi-wavelength observations suggest that the accretion disk in the hard and intermediate states of X-ray binaries (XRBs) and active galactic nuclei (AGN) transitions from a cold, thin disk at large distances into a hot, thick flow close to the black hole. However, the formation, structure and dynamics of such truncated disks are poorly constrained due to the complexity of the thermodynamic, magnetic, and radiative processes involved. We present the first radiation-transport two-temperature general relativistic magnetohydrodynamic (GRMHD) simulations of truncated disks radiating at ~35% of the Eddington luminosity with and without large-scale poloidal magnetic flux. We demonstrate that when a geometrically-thin accretion disk is threaded by large-scale net poloidal magnetic flux, it self-consistently transitions at small radii into a two-phase medium of cold gas clumps floating through a hot, magnetically dominated corona. This transition occurs at a well-defined truncation radius determined by the distance out to which the disk is saturated with magnetic flux. The average ion and electron temperatures in the semi-opaque corona reach, respectively, T_i ~ 10^10K and T_e ~ 5 10^8K. The system produces radiation, powerful collimated jets and broader winds at the total energy efficiency exceeding ~90%, the highest ever energy extraction efficiency from a spinning black hole by a radiatively efficient flow in a GRMHD simulation. This is consistent with jetted ejections observed during XRB outbursts. The two-phase medium may naturally lead to broadened iron line emission observed in the hard state.

description: Lie symmetries of a Novikov geometrically integrable equation are found and group-invariant solutions are obtained. Local conservation laws up to second order are established as well as their corresponding conserved quantities. Sufficient conditions for the $L^1$ norm of the solutions to be invariant are presented, as well as conditions for the existence of positive solutions. Two demonstrations for unique continuation of solutions are given: one of them is just based on the invariance of the $L^1$ norm of the solutions, whereas the other is based on well-posedness of Cauchy problems. Finally, pseudo-spherical surfaces determined by the solutions of the equation are studied: all invariant solutions that do not lead to pseudo-spherical surfaces are classified and the existence of an analytic metric for a pseudo-spherical surface is proved using conservation of solutions and well-posedness results.

description: Objective: The study aims to assess the impact of COVID-19 on healthcare workers’ work-related stress during the first wave of the pandemic in Italy. The main objective is to investigate the existence of a positive correlation between hopelessness and burnout, assuming that burnout may be a risk factor for the development of hopelessness, and to analyze the role that trait Emotional Intelligence (TEI) and changes in workload could have in this relationship. Furthermore, evaluate any significant differences in burnout and hopelessness levels in the function of some demographic variables, such as gender, professional profiles, and different working zones of Italy, to better understand how the diverse diffusion of pandemic had affected Italian healthcare workers. Methods: An online survey was used to collect data between April and June, 2020, with 562 responses among nurses (52.1%) and physicians (47.9%). Demographics and changes in workload and work conditions were collected through an ad hoc questionnaire. The Trait Emotional Intelligence Questionnaire- Short Form (TEIQue-SF), The Beck Hopelessness Scale (BHS), and the Link Burnout Questionnaire (LBQ) were used to assess Trait Emotional Intelligence (TEI), hopelessness, and burnout, respectively. Results: Correlation analysis showed a significant positive relationship between hopelessness and each burnout dimension. TEI showed negative correlations both with burnout dimensions and hopelessness. Significant differences in burnout and hopelessness levels emerged as a function of some demographic variables such as gender, professional profiles (nurses or physicians), and different working zone of Italy (northern or southern). Results showed that TEI partially mediated the relationship between hopelessness and every burnout dimension, while the interaction of changes in workload was non-significant. Discussion: The mediating role of TEI in the burnout-hopelessness relationship partly explains the protective role that individual factors had on healthcare workers’ mental health. Our findings support the need to integrate considerations on both psychological risk and protective factors into COVID-19 care, including the monitoring of psychological symptoms and social needs, especially among healthcare workers.
Conformal blocks on a 2-sphere with indistinguishable punctures and implications on black hole entropy

description: The dimensionality of the Hilbert space of a Chern-Simons theory on a 3-fold, in the presence of Wilson lines carrying spin representations, had been counted by using its link with the Wess-Zumino theory, with level $k$, on the 2-sphere with points (to be called punctures) marked by the piercing of the corresponding Wilson lines and carrying the respective spin representations. It is shown, in the weak coupling (large $k$) limit, the formula decouples into two characteristically distinct parts; one mimics the dimensionality of the Hilbert space of a collection of non-interacting spin systems and the other is an effective overall correction contributed by all the punctures. The exact formula yield from this counting has been shown earlier to have resulted from the consideration of the punctures to be distinguishable. We investigate the same counting problem by considering the punctures to be indistinguishable. Although the full formula remains undiscovered, nonetheless, we are able to impose the relevant statistics for indistinguishable punctures in the approximate formula resulting from the weak coupling limit. As an implication of this counting, in the context of its relation to that of black hole entropy calculation in quantum geometric approach, we are able to show that the logarithmic area correction, with a coefficient of $-3/2$, that results in this method of entropy calculation, in independent of whether the punctures are distinguishable or not.

In this first part of the series, we classify the cases m = 3, 4 and 6 when the polygons are finite. Then we show that the infinite case is very different, and construct examples which strongly deviate from the finite case. A number of general structure theorems are also obtained. We introduce the theory of locally finitely generated generalized polygons and locally finitely chained generalized polygons along the way.

The Privatization of Social Work
Creators: name: Benn, Jenna
Publisher: name: Columbia Social Work Review
Year: 2019

description: Since the 1980s, social workers have increasingly left the service of the public sector and entered into private practice. A substantial number of today’s social workers practice for-profit client-based therapy rather than agency-based public service. These recent changes are causing critics to question whether social work’s new focus on for-profit services has deviated from social work’s original purpose to forge allegiances with the poor, the disadvantaged, and the oppressed. Is this change in focus an abandonment of social work’s historical principles? Or is it simply a modern and logical evolution? This paper examines the debate between private and public social work practice. It describes how social work historically emerged and evolved on two interconnected fronts, one with a focus on change at the community level, and one with a focus on change at the individual level. This paper posits that the two approaches are not irreconcilable and that healthy debate has led, and continues to lead, the profession forward.

description: Recently, a model of modified gravity plus single scalar field model was proposed, in which the scalar couples both to the standard Riemannian volume form given by the square root of the determinant of the Riemannian metric, as well as to another non-Riemannian volume form given in terms of an auxiliary maximal rank antisymmetric tensor gauge field. This model provides an exact unified description of both dark energy (via dynamically generated cosmological constant) and dark matter (as a "dust" fluid due to a hidden nonlinear Noether symmetry). In this paper we test the model against Supernovae type Ia experimental data and investigate the future Universe evolution which follows from it. Our results show that this model has very interesting features allowing various scenarios of Universe evolution and in the same time perfectly fits contemporary observational data. It can describe exponentially expanding or finite expanding Universe and moreover, a Universe with phase transition of first kind. The phase transition occurs to a new, emerging at some time ground state with lower energy density, which affects significantly the Universe evolution.

description: The capillary traction of a liquid contact line causes highly localized deformations in soft solids, tremendously slowing down wetting and dewetting dynamics by viscoelastic braking. Enforcing nonetheless large velocities leads to the so-called stick-slip instability, during which the contact line periodically depins from its own wetting ridge. The mechanism of this periodic motion and, especially, the role of the dynamics in the fluid have remained elusive, partly because a theoretical description of the unsteady soft wetting problem is not available so far. Here we present the first numerical simulations of the full unsteady soft wetting problem, with a full coupling between the liquid and the solid dynamics. We observe three regimes of soft wetting dynamics: steady viscoelastic braking at slow speeds, stick-slip motion at intermediate speeds, followed by a region of viscoelastic braking where stick-slip is suppressed by liquid damping, which ultimately gives way to classical wetting dynamics, dominated by liquid dissipation.

description: Markov logic networks (MLNs) reconcile two opposing schools in machine learning and artificial intelligence: causal networks, which account for uncertainty extremely well, and first-order logic, which allows for formal deduction. An MLN is essentially a first-order logic template to generate Markov networks. Inference in MLNs is probabilistic and it is often performed by approximate methods such as Markov chain Monte Carlo (MCMC) Gibbs sampling. An MLN has many regular, symmetric structures that can be exploited at both first-order level and in the generated Markov network. We analyze the graph structures that are produced by various lifting methods and investigate the extent to which quantum protocols can be used to speed up Gibbs sampling with state preparation and measurement schemes. We review different such approaches, discuss their advantages, theoretical limitations, and their appeal to implementations. We find that a straightforward application of a recent result yields exponential speedup compared to classical heuristics in approximate probabilistic inference, thereby demonstrating another example where advanced quantum resources can potentially prove useful in machine learning.

Solidarity and Justice in Health Care. A Critical Analysis of their Relationship
Creators: name: Ter Meulen, Ruud
Publisher: name: Diametros
Year: 2015

description: This article tries to analyze the meaning and relevance of the concept of solidarity as compared to the concept of justice. While ‘justice’ refers to rights and duties (Moralität), the concept of solidarity refers to relations of personal commitment and recognition (Sittlichkeit). The article wants to answer the question whether solidarity and liberal justice should be seen as mutually exclusive or whether both approaches should be regarded as complementary to each other. The paper starts with an analysis of liberal theories of justice which are followed by an analysis of the descriptive and a moral understanding of the concept of solidarity. The importance of solidarity lies in its relational aspects, particularly its emphasis on cooperation and commonality. The paper argues that while solidarity is more fundamental than justice, both concepts are important for the arrangement of health care practices. The paper gives special attention to the concept of decent care, reflective solidarity and humanitarian solidarity which is seen as fundamental for all health care policies and care practices.

description: We show that if the fundamental group of the complement of a rationally homologically fibered knot in a rational homology 3-sphere is bi-orderable, then its Alexander polynomial has at least one positive real root. Our argument can be applied for a finitely generated group which is an HNN extension with certain properties.

Particle-in-cell simulations of the twisted magnetospheres of magnetars

description: The magnetospheres of magnetars are believed to be filled with electron-positron plasma generated by electric discharge. We present a first direct numerical experiment showing how the plasma is created in an axisymmetric closed magnetosphere. The $e^\pm$ discharge occurs in response to twisting of the magnetic field lines by a shear deformation of the magnetar surface, which launches electric currents into the magnetosphere. The simulation shows the formation of an electric "gap" with unscreened electric field ($\mathbf{E}\cdot \mathbf{B}\neq 0$) that continually accelerates particles along the magnetic field lines and sustains pair creation. The accelerating voltage is self-regulated to the threshold of the $e^\pm$ discharge. It controls the rate of energy release and the lifetime of the magnetic twist. The simulation follows the global evolution of the twisted magnetosphere over a long time and demonstrates its gradual resistive untwisting. A vacuum cavity forms near the star and expands, gradually erasing magnetospheric electric currents $j$. The active j-bundle shrinks with time and its footprints form shrinking hot spots on the magnetar surface bombarded by the created particles.

Project Lyra: A Mission to 1I/'Oumuamua without Solar Oberth Manoeuvre

description: To settle the question of the nature of the interstellar object 1I/'Oumuamua requires in-situ observations via a spacecraft, as the object is already out of range of existing telescopes. Most previous proposals for reaching 1I/'Oumuamua using near-term technologies are based on the Solar Oberth Manoeuvre (SOM), as trajectories without the SOM are generally significantly inferior in terms of lower mission duration and higher total velocity requirement. While the SOM allows huge velocity gains, it is also technically challenging and thereby increases programmatic and mission-related risks. In this paper, we identify an alternative route to the interstellar object 1I/'Oumuamua, based on a launch in 2028, which does not require a SOM but has a similar performance as missions with a SOM. It instead employs a Jupiter Oberth Manoeuvre (JOM) with a total time of flight of around 26 years or so. The efficacy of this trajectory is a result of it significantly reducing the $Δ$V to Jupiter by exploiting the VEEGA sequence. The total $Δ$V of the trajectory is 15.8 $kms^{-1}$ and the corresponding payload mass is 115 kg for a SLS Block 1B or 241 kg for a Block 2. A further advantage of the JOM is that the arrival speed relative to 1I/'Oumuamua is approximately 18 $kms^{-1}$, much lower than the equivalent for the SOM of around 30 $kms^{-1}$.

A Multi-Wavelength Analysis of Protocluster Environments at the Cosmic Noon
Creators: name: Gallego, Sofia
Publisher: name: Zenodo
Year: 2023

description: Studying galaxy evolution at the cluster and protocluster scale plays a crucial role in unraveling the intricate interplay between large-scale structure and internal galaxy processes. We present a multi-wavelength analysis of a protocluster at redshift z=2.3, which provides a unique opportunity to investigate the evolution of galaxies at a cosmic epoch of enhanced star formation and where environmental effects are most significant. Leveraging extensive data spanning the near-infrared to the ultraviolet, we uncover complex morphological and kinematical features of the extended gas in Lyman alpha, C IV, and He II associated with the protocluster and a remarkably high local density of AGN activity. These observations suggest ongoing feedback processes between AGNs and the surrounding gas, as well as an intricate formation process of the circum-galactic gas within the context of large-scale structures. Our study highlights the need for state-of-the-art theoretical interpretations of the interaction between galaxies and their surrounding gas up to intergalactic scales, as well as serving as a precursor to future large surveys targeting a statistical sample of galaxies that will revolutionize our understanding of galaxy evolution in the cosmic landscape.
The Hospice Movement
Creators: name: Chipetz, Samantha
Publisher: name: Columbia Social Work Review
Year: 2019

description: With the elderly population growing, there is a great need to improve the quality of end-of-life care. Traditionally, the healthcare industry has focused on the pathology-oriented medical model when assisting terminally ill patients. This focus can lead to patients feeling depressed, anxious, and hopeless about the dying process. By incorporating spirituality into the dying process, the hospice movement diverged from this medical model, but the role of social workers is often divided between these two very different paradigms. This paper discusses spiritual practice theories that hospice social workers can use to benefit the well-being of terminally ill patients while working within the current health care system.

Response to Ruud ter Meulen

description: In addition to thinking about the meanings of solidarity, it is important to address how solidarity of the appropriate sort can be cultivated. Possibilities include the transformative power of key individuals or events; and the role of institutions. In health care it is suggested that a combination of the two strategies is required. Professional conduct includes not only acting in 'face to face' delivery, but also engaging with those institutions which enable or disable certain ways of acting, so that they are constantly subject to revision to ensure that they facilitate the provision of decent healthcare.
