description: The United Nations Stabilization Mission in the DR Congo (MONUSCO) boasts a fourteen-year presence in the Democratic Republic of the Congo (hereafter, the DRC, the DR Congo, or “Congo”). The lives of many civilians in eastern Congo remain punctuated by episodes of violence and instability, often at the hands of foreign and Congolese rebel militias and, at times, as a result of human rights abuses by the Congolese police force (PNC) and military (Cakaj 2010, Oxfam 2014). The Rwandan genocide of 1994 and the exodus of Rwandan genocidaires into neighboring DRC served as a catalyst for Congo’s current instability (Nzongola 2014, BBC 2014). Though not the sole determinant of contemporary violence, the Rwandan refugee crisis exacerbated existing tensions in the Congo. In response to a mushrooming humanitarian crisis and international violation of Congolese sovereignty on the part of rebel militias the United Nations (UN) authorized the UN Organization Mission in the DR Congo (MONUC) in 2000. Throughout Congo’s contemporary history, a complex web of armed groups relied on local and regional political, economic, and military support to advance their aims in the country’s eastern regions, often with grave consequences for Congolese civilians (Bafilemba and Mueller 2013). In 2010 the mission changed its name to the UN Stabilization Mission in the DR Congo (MONUSCO) to reflect its objectives: “protect, stabilize, and consolidate peace” (MONUSCO at a Glance 2014). In the spring of 2013, the UN Security Council (UNSC) significantly enhanced
MONUSCO’s offensive capacity through issuing UNSC Resolution 2098, which created a Force Intervention Brigade (FIB) charged with proactively neutralizing armed groups in eastern Congo. The resolution also identified civilian protection as the highest mission priority and granted MONUSCO the authority to use drone technology to monitor human rights abuses(UNSC 2013). This thesis surveys MONUSCO’s civilian protection capacity as observed in June
and July of 2014, fifteen months after the enactment of Resolution 2098. The central question follows: to what extent has UNSC Resolution 2098 impacted MONUSCO’s capacity to protect Congolese civilians? In the opening text of this analysis, I included a statement from a Congolese community member, in which he laments the UN’s inability to deliver on its promises of peace in eastern Congo. Through literary analysis and qualitative interview data, I construct an argument to explain why Resolution 2098 failed to enhance the UN’s capacity to deliver the peace dividends of civilian protection to Congolese civilians in the fifteen months following its enactment.

description: Explicit formulae are given for the consistent truncation of massive type IIA supergravity on the six-sphere to the SU(3)--invariant sector of $D=4$ ${\cal N}=8$ supergravity with dyonic ISO(7) gauging. These formulae are then used to construct AdS$_4$ solutions of massive type IIA via uplift on $S^6$ of the critical points of the $D=4$ supergravity with at least SU(3) symmetry. We find a new ${\cal N}=1$ solution with SU(3) symmetry, a new non-supersymmetric solution with SO(6) symmetry, and recover previously known solutions. We quantise the fluxes, calculate the gravitational free energies of the solutions and discuss the stability of the non-supersymmetric ones. Among these, a (previously known) G$_2$--invariant solution is found to be stable.

description: Stochastic-Beta-Relaxation (SBR) provides a characterisation of the glass crossover in discontinuous Spin-Glasses and Supercoooled liquid. Notably it can be derived through a rigorous computation from a dynamical Landau theory. In this paper I will discuss the precise meaning of this connection in a language that does not require familiarity with statistical field theory. I will discuss finite-size corrections in mean-field Spin-Glass models and loop corrections in finite-dimensional models that are both described by the dynamical Landau theory considered. Then I will argue that the same Landau theory can be associated to supercooled liquid described by Mode-Coupling-Theory invoking a physical principle of time-scale invariance.

description: The theory of Resource Based View (RBV) posits the use of internal resources for competitive advantage which is often evaluated using four questions on value (V), rarity (R), imitability (I) and organisation (O), also known as the VRIO framework. This research focuses on the organisational resource of tacit knowledge which is characterised by knowledge that is difficult to transfer. Identification and transfer of tacit knowledge stock is one of the major research problems in the knowledge management discipline. The purpose of this research is to explore whether tacit knowledge stock can be identified using self-assessment of skills to enable knowledge transfer. The research questions of this study include: RQ 1: To what extent can self-assessment of skills help to identify tacit knowledge stock? And, RQ 2: What role does identifying tacit knowledge stock play in knowledge transfer? Using Design Science Research (DSR) methodology, an artefact is developed, implemented and evaluated to answer the research questions. The artefact is represented as a model that expresses the relationships between three constructs namely: (i) self-assessment of skills, (ii) tacit knowledge stock and (iii) knowledge transfer. The model is operationalised using a software tool based on the Skills Framework for the Information Age (SFIA). The model is evaluated via semi-structured interviews with twenty-one staff of the Information Technology (IT) department in a case study organisation. This research found that knowledge transfer could be enabled by the identification of tacit knowledge stock. Other enabling factors that affected tacit knowledge transfer were also identified, namely, sender’s prior understanding of the receivers’ tacit knowledge stock, sender’s willingness to transfer knowledge, person-organisation fit, similar knowledge area, organisational culture and self-awareness of tacit knowledge stock. This research argues that the self-assessment of skills is a useful method of identifying tacit knowledge stock. Majority of the research participants found that the self-assessment of skills was effective for identifying tacit knowledge stock at an individual level as compared to an organisational level. The major contribution of this research is the development of the model that can be used to facilitate tacit knowledge transfer based on self-assessment of skills. This model extends the literature of the knowledge management discipline by explaining the relationship between tacit knowledge stock and transfer based on self-assessment of skills. The evaluation of the model confirms its practical application in knowledge-intensive organisations that intend to understand tacit knowledge stock in order to facilitate tacit knowledge transfer.
Tipping the Scales: Improving Utilization of Mental Health Care in Military Veterans

description: Veterans frequently endorse symptoms of mental illness while not utilizing mental healthcare to
its full extent. Previous studies have focused on barriers to veteran mental healthcare, but have
lacked analysis of what leads to the barriers themselves, as well as enroll sampling frames both
longitudinal and representative of the veteran population. This study contributes to the literature
in all of these ways, through multivariate regression and mediation analysis of a sample of 1090
veterans randomly selected from a database of over one million US veterans. The sample was
gathered in two waves, and consisted of a survey that asked a wide variety of questions.
Analyses revealed that PTSD symptoms (parameter estimate= 4.220, p<.0001), good social
support (parameter estimate= -1.344, p<.0001), and perceptions “it’s up to me to handle my own
problems” (parameter estimate= -.541, p<.0001) were strong indicators of number of visits to a
mental health professional in the next year. Mediation analysis showed PTSD to have a direct,
positive effect (β =5.679, t=9.702, p<.0001) on number of visits, but also an indirect, negative
effect on number of visits when the “its up to me” barrier was used as a mediator. Additionally,
social support was also shown to have a direct, negative effect (β =-.372, t=-4.081, p<.0001) on
number of visits, but an indirect, positive effect when the “its up to me” barrier was used as a
mediator. These results suggest a dual pathway in both PTSD and social support and their effects
on number of visits when the “it’s up to me” barrier is considered. Implications include clinicians
and policy makers addressing the importance of belief systems and the role of social support to
increase mental health utilization.

description: We provide an example of a 4D theory that exhibits the Contino-Pomarol-Rattazzi mechanism, where breaking conformal symmetry by an almost marginal operator leads to a light pseudo-Goldstone boson, the dilaton, and a parametrically suppressed contribution to vacuum energy. We consider SUSY QCD at the edge of the conformal window and break conformal symmetry by weakly gauging a subgroup of the flavor symmetry. Using Seiberg duality we show that for a range of parameters the singlet meson in the dual theory reaches the unitarity bound, however, this theory does not have a stable vacuum. We stabilize the vacuum with soft breaking terms, compute the mass of the dilaton, and determine the range of parameters where the leading contribution to the dilaton mass is from the almost marginal coupling.

title: The use of psychotherapy as an effective treatment for grief and loss for persons diagnosed with dementia and their caregiver: a systematic review of the literature

description: The effects of dementia can be overwhelming not only for those diagnosed with dementia, but also their caregivers. Psychotherapy may be one way that can help the dyad better cope with this life-changing diagnosis, however whether psychotherapy is effective remains unclear. A systematic literature review was conducted to identify effective psychotherapeutic interventions to ameliorate the effects of grief and loss experienced by the dyad of the person experiencing dementia and their caregiver. During the screening process a total of 1020 records were identified via searching University of Southern Queensland databases using the field 'abstract'. After removing 354 duplicate records a total of 666 remained. Further screening by the researcher and a research assistant resulted in 30 articles being short-listed for full text review using title and abstract. On completion of this procedure it was found that no literature met the inclusion criteria specifically aimed to explore psychotherapy as an effective treatment for grief and loss experienced by the dyad of persons with dementia and their caregiver. In collaboration with the researcher’s supervisors, a revised inclusion criteria was developed that moved from treatment aimed at the dyad to include research where either the caregiver, or the person with dementia, individually was a recipient of psychotherapeutic intervention. The 666 articles were re-screened and a total of eight articles were short-listed for full-text review. Four of the eight articles were discarded due to not meeting the inclusion criteria. On review it was found that the four articles included for review and synthesis focused on grief and loss experienced by the caregiver. No literature was identified relating to persons with dementia receiving psychotherapeutic intervention to ameliorate the effects of grief and loss. Within the four articles reviewed and synthesised three interventions were identified as being used. These interventions included: (1) telephone-based cognitive behavioural therapy, (2) coaching, and (3) the five component 'Easing the Way' interventions (MacCourt, McLennan, Somers & Krawczyk, 2017; Meichsner, Schinkothe, & Wilz., 2016; Meichsner & Wilz., 2016; Ott, Kelber, & Blaylock, 2010). These interventions were found to be potentially beneficial in ameliorating the experience of grief and loss on the part of the caregiver. With further research these findings may be useful in its implications in supporting the dyad of caregivers and persons with dementia by guiding the future direction of psychotherapeutic intervention.
The Relationship Between Muscle Length Imbalance and the Occurrence of Scoliosis and Back Pain in Collegiate Female Gymnasts
Creators: name: Campbell, Caroline

description: Gymnastics at the collegiate level is unique in that these elite athletes begin high volume and high intensity training at a very young age. The sport is unilateral meaning each gymnast has a dominant leg that always leads in split leaps and a dominant side to which they always twist. The combination of these factors puts the gymnast at risk for developing muscle length imbalances between their dominant and non-dominant sides. With such a high incidence of back pain in this population, more research was needed to investigate any relationships with potential muscle length imbalances. The purpose of this study was to determine if collegiate women gymnasts exhibit muscle length imbalances in the lower extremity and if these imbalances were related to back pain, the amount of spinal curvature, or both. Muscle length measurements of the iliopsoas, rectus femoris, hamstrings, and quadratus lumborum were taken on 13 UNC female varsity gymnasts. Participants completed a Modified Oswestry Disability Index if they experienced back pain. Using the angle tool on Image J software, the amount of spinal curvature for each gymnast was measured from a dual energy x-ray absorptiometry (DXA) scan. A statistically significant difference in length was found between the dominant and non-dominant sides for the hamstrings (p=0.001). While there were not any statistically significant imbalances for the other muscle groups, there were differences between sides that carry clinical significance. There was a statistically significant relationship between the amount of rectus femoris imbalance and back pain (R=0.797; p=0.001) and the amount of quadratus lumborum imbalance and spinal curvature (R=0.683; p=0.010). The results of this study indicate that the unilateral nature of gymnastics can cause the development of muscle length imbalances. These imbalances then contribute to back pain and spinal curvature, which may have long-term implications for the athlete.

description: IC-planar graphs are those graphs that admit a drawing where no two crossed edges share an end-vertex and each edge is crossed at most once. They are a proper subfamily of the 1-planar graphs. Given an embedded IC-planar graph $G$ with $n$ vertices, we present an $O(n)$-time algorithm that computes a straight-line drawing of $G$ in quadratic area, and an $O(n^3)$-time algorithm that computes a straight-line drawing of $G$ with right-angle crossings in exponential area. Both these area requirements are worst-case optimal. We also show that it is NP-complete to test IC-planarity both in the general case and in the case in which a rotation system is fixed for the input graph. Furthermore, we describe a polynomial-time algorithm to test whether a set of matching edges can be added to a triangulated planar graph such that the resulting graph is IC-planar.
Slowly rotating regular black holes with a charged thin shell

description: We obtain rotating solutions of regular black holes which are constructed of de Sitter spacetime with the axisymmetric stationary perturbation within the timelike charged thin shell and the Kerr-Newman geometry with sufficiently small rotation outside the shell. To treat the slowly rotating thin shell, we employ the method developed by de la Cruz and Israel. The thin shell is assumed to be composed of a dust in the zero-rotation limit and located inside the inner horizon of the black hole solution. We expand the perturbation in powers of the rotation parameter of the Kerr-Newman metric up to the second order. It is found that with the present treatment, the stress tensor of the thin shell in general has anisotropic pressure, i.e., the thin shell cannot be composed of a dust if the rotational effects are taken into account. However, the thin shell can be composed of a perfect fluid with isotropic pressure if the degrees of freedom appearing in the physically acceptable matching of the two distinct spacetimes are suitably used. We numerically investigate the rotational effects on the spherically symmetric charged regular black hole obtained by Uchikata, Yoshida and Futamase in detail.

The Associations Between Football Exposure, Concussion History and Playing Position on Cerebral White Matter Integrity and Neurocognitive Performance

Year: 2015

description: Diffusion tensor imaging (DTI) has emerged as an important tool for quantitative analysis
of white matter (WM) integrity following sport-related concussions. The purpose of this research
was to investigate the variances in WM integrity (defined by fractional anisotropy (FA) and
medial diffusivity (MD)) and neurocognitive performances in retired college and professional
football athletes based on concussion history, duration of playing career, and playing position.
MRI scans and neurocognitive test scores from 32 former college and 31 former age-matched
professional players (avg age=58.5 SD=3.7) were compared. A permuted, voxel-wise 3x2
ANOVA was performed on the WM skeleton to investigate the main and interaction effects on
WM integrity. Threshold-free cluster enhancement (TFCE) was used to identify clusters of
significantly different FA or MD and post-hoc univariate analyses were used to determine the
direction of interaction effects. A priori alpha level was set at 0.05 after correction for multiple
comparisons. Differences in FA were observed in 3 clusters in the forceps minor and genu of the
corpus callosum for the concussion by position interaction. Post-hoc analysis of the peak voxels
within each cluster revealed consistently lower FA in non-speed athletes with 3+ concussions
as
compared to those with 01
concussions (Cohen’s d: 0.89, 0.95, and 1.29; P<0.05). No clear
differences in neurocognitive abilities were identified. Our results suggest a history of multiple
concussions is associated with lower FA in former non-speed position players compared to speed
players, particularly in frontal white matter tracts. We did not observe main effects of football
exposure, suggesting that without concussive injuries, added football exposure does not account
for variances in white matter integrity and neurocognitive abilities. A limitation of these results
is the lack of a control group without history of football participation

description: As a diagnosis, posttraumatic stress disorder (PTSD) has been associated with violence committed by veterans in many studies; however, a potential link to specific PTSD symptoms has received relatively less attention. This paper contains two studies that highlight the relationship between PTSD symptoms and violent behavior in Iraq and Afghanistan Veterans. The interaction of alcohol misuse and distinct types of violence are also explored. Participants were randomly sampled from a roster of all separated U.S. military service members or national guard/reservists who served after September 11th, 2001. Data were collected at baseline and one-year follow-up from a national sample of N=1090 veterans, from 50 states and all military branches. A sub-sample of these veterans with PTSD or Sub-threshold PTSD (N=274) was investigated for the first study. Hyper-arousal symptoms were the most frequently endorsed. Results showed significant interactions between all symptom clusters and alcohol misuse when predicting severe violence and any aggressive act. This study reveals a consistent link between symptoms and alcohol misuse on violence. The second study utilized a weighted sample of N=866 veterans. Anger symptoms at baseline predicted higher odds of family violence at follow-up, both severe (OR = 1.30, CI [1.13, 1.48], p < .0001) and any (OR = 1.28, CI [1.19, 1.37], p < .0001). PTSD flashback symptoms at baseline predicted higher odds of stranger violence at follow-up, both severe (OR = 1.26, CI [1.11, 1.42], p < .0001) and any (OR = 1.16, CI [1.05, 1.28], p = .0029). Analyses revealed that males were more likely to engage in stranger violence whereas females were more likely to endorse aggression in the family context. The results provide limited support to the hypothesis that PTSD “flashbacks” in veterans are linked to violence. The differing multivariate models illustrate distinct veteran characteristics associated with specific types of violence.
A Stakeholder Analysis: Stakeholders' perceptions of chronic pain management in older adults who reside in a long-term care facility

description: Chronic pain remains a major public health concern throughout the United States, but its
high prevalence among older adults who reside in long-term care facilities (LTCF) emphasizes the need to focus research efforts on chronic pain management. Chronic pain in older adults who live in LTCFs is consistently undertreated and unrecognized by staff. The literature identifies the following four challenges to recognizing and managing chronic pain in older adults who live in LTCFs: generational differences; cognitive impairment; non-standardization of pain protocols and guidelines; and non-uniform pain assessment tools and pain scales. This honors project is part of a project funded by the North Carolina AHEC Innovation Grant in order to conduct a Quality Improvement Project on the quality issue of chronic pain management. The purpose of
my project was to conduct a stakeholder analysis exploring the stakeholders’ perceptions of chronic pain management in older adults who reside in the LTCF. The analysis revealed nine themes that were presented to the School of Nursing team. We discussed and examined several potential areas of intervention to suggest to the leadership team at Happy Meadows. This Quality Improvement Project will not only aid the leadership team at Happy Meadows in developing a new pain management protocol, but also it will inform future quality improvement efforts to improve chronic pain management in LTCFs.

description: A tidal disruption event, which occurs when a star is destroyed by the gravitational field of a supermassive black hole, produces a stream of debris, the evolution of which ultimately determines the observational properties of the event. Here we show that a post-periapsis caustic -- a location where the locus of gas parcels comprising the stream would collapse into a two-dimensional surface if they evolved solely in the gravitational field of the hole -- occurs when the pericenter distance of the star is on the order of the tidal radius of the hole. It is demonstrated that this "pancake" induces significant density perturbations in the debris stream, and, for stiffer equations of state (adiabatic index $γ\gtrsim 5/3$), these fluctuations are sufficient to gravitationally destabilize the stream, resulting in its fragmentation into bound clumps. The results of our findings are discussed in the context of the observational properties of tidal disruption events.

Polarizing efficiency as a guide of grain growth and interstellar magnetic field properties

description: We interpret the relation between the polarizing efficiency $P_{\max}/E(B-V)$ and the wavelength of the maximum polarization $λ_{\max}$ observed for 17 objects (including 243 stars) separated into two groups: "dark clouds" and "open clusters". The objects are assigned to one of the groups according to the distribution of the parameter $λ_{\max}$. We use the model of homogeneous silicate and carbonaceous spheroidal particles with the imperfect alignment and a time-evolving size distribution. The polarization is assumed to be mainly produced by large silicate particles with the sizes $r_{V} \ga r_{V,\rm cut}$. The models with the initial size distribution reproducing the average curve of the interstellar extinction fail to explain the values of $λ_{\max} \ga 0.65\,\mkm$ observed for several dark clouds. We assume that the grain size distribution is modified due to accretion and coagulation, according to the model of Hirashita \& Voshchinnikov (2014). After including the evolutionary effects, $λ_{\max}$ shifts to longer wavelengths on time-scales $\sim 20 (n_\mathrm{H}/10^3 \mathrm{cm}^{-3})^{-1}$ Myr where $n_\mathrm{H}$ is the hydrogen density in molecular clouds where dust processing occurs. The ratio $P_{\max}/E(B-V)$ goes down dramatically when the size of polarizing grains grows. The variations of the degree and direction of particle orientation influence this ratio only moderately. We have also found that the aspect ratio of prolate grains does not affect significantly the polarizing efficiency. For oblate particles, the shape effect is stronger but in most cases the polarization curves produced are too narrow in comparison with the observed ones.

description: By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of those pulsars. Gravitational waves (GWs) from supermassive black hole binaries (SMBHBs) are an exciting potentially detectable source of such correlations. We describe a straight-forward technique by which a PTA can be "phased-up" to form time series of the two polarisation modes of GWs coming from a particular direction of the sky. Our technique requires no assumptions regarding the time-domain behaviour of a GW signal. This method has already been used to place stringent bounds on GWs from individual SMBHBs in circular orbits. Here, we describe the methodology and demonstrate the versatility of the technique in searches for a wide variety of GW signals including bursts with unmodeled waveforms. Using the first six years of data from the Parkes Pulsar Timing Array, we conduct an all-sky search for a detectable excess of GW power from any direction. For the lines of sight to several nearby massive galaxy clusters, we carry out a more detailed search for GW bursts with memory, which are distinct signatures of SMBHB mergers. In all cases, we find that the data are consistent with noise.

The Urban Cowboy

Publisher: name: RSAJournal
Year: 2023

description: The article addresses how the mythical Western imaginary goes beyond its geopolitical borders, examining its influence on other urban landscapes such as New York. The city that never sleeps also captured a paradigmatic fascination for the concept of the West. This has been shown in Italian American culture and literature since the times of this ethnic settlement, although as part of the US cultural imagination at large the notion of the West is rarely bound to a concrete physical space. The article analyzes not only Italian or Italian American positions within transnational Western literature, but also the crucial interplay of gender representation in configuring old and new myths. To this end, the analysis concentrates on two central elements of the classical West(ern): the cowboy and the frontier, although reconceptualized in the context of US twentieth century immigration and urbanization. These two elemental features serve to identify the impact of US Westerns on Italian American culture in general and literature in particular through Mario Puzo’s novel The Fortunate Pilgrim (1965). As a result of shifting the critical attention about the West(ern) to the understudied space of the city, this article aims at providing an innovative insight to recover a figure which is both historical and legendary, that of the so-called urban cowboy.

Eliciting Vulnerable Populations' Preferences of Colorectal Cancer Screening: A Systematic Review
Creators: name: Lee, Samuel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: AbstractBackground: Patient preferences are important to consider in the decision-making process for colorectal cancer (CRC) screening. Vulnerable populations, especially, exhibit lower screening uptake. This systematic review describes studies on vulnerable populations’ preferences regarding CRC screening.Methods: We searched the PubMed, CINAHL, PsychInfo, Scopus, and Web of Science databases for articles published between January 1, 1996 to December 31, 2017. We screened studies for eligibility and using a standardized spreadsheet, abstracted and compared study designs and outcomes.Results: A total of 44 articles were selected and are organized by the types of vulnerable population(s) whose preferences are reported. Of these studies, 17 report on preferences among racial/ethnic minorities, 11 among multiracial/multiethnic minorities, 7 among low-income groups, 6 among veterans, 2 among rural residents, and 1 among immigrants.Conclusion: The heterogeneity in outcomes, study design, and populations of the selected studies demonstrate the wide spectrum of preferences of vulnerable populations. No specific modality was overwhelmingly supported by vulnerable populations, but attributes such as accuracy and sensitivity proved to be important features. An increase in the CRC screening rate may be achieved through the alignment of vulnerable populations’ preferences with provider preferences through shared decision making.

description: This thesis is expected to make a major contribution to diversity management practices within Australia – and to the literature more broadly - by explicating what type of strategies and support mechanisms are required for women to excel in leadership positions. The thesis explores the status-imposed limitations on senior executive women’s agency in Australian workplaces through the lens of status characteristics theory (SCT). It adds to existing theory by employing an empirical lens of the actual workplace experiences of Australian women in leadership. This thesis suggests that women leaders are aware of status-imposed limitations on their agency and identify a range of successful behaviours to shorten the path of relevance and increase their power-prestige rankings. Findings suggest that status is as important as power and resources in perceptions of workplace competence. Perceptions through cultural assessments are made about women and these perceptions limit women leaders’ agency. Furthermore, this thesis provides significant empirical confirmation that personal and institutional support mechanisms significantly assist women leaders’ progression. The thesis extends current thinking and elevates status beliefs and characteristics to those of resources and power.

description: We study the internal structure of a static and spherically symmetric neutron star in the framework of an in-medium modified chiral soliton model. The Equations of State describing an infinite and asymmetric nuclear matter are obtained introducing the density dependent functions into the low energy free space Lagrangian of the model starting from the phenomenology of pionic atoms. The parametrizations of density dependent functions are related to the properties of isospin asymmetric nuclear systems at saturation density of symmetric nuclear matter $ρ_0\simeq 0.16$~fm$^{-3}$. Our results, corresponding to the compressibility of symmetric nuclear matter in the range $250\,\mbox{MeV}\le K_0\le 270\,\mbox{MeV}$ and the slop parameter value of symmetry energy in the range $30\,\mbox{MeV}\le L_S\le 50\,\mbox{MeV}$, are consistent with the results from other approaches and with the experimental indications. Using the modified Equations of State, near the saturation density of symmetric nuclear matter $ρ_0$, the extrapolations to the high density and highly isospin asymmetric regions have been performed. The calculations showed that the properties of $\sim 1.4M_\odot$ and $\sim 2M_\odot$ neutron stars can be well reproduced in the framework of present approach.

Picturing Italy
Creators: name: Santangeli Valenzani, Giuliano
Publisher: name: RSAJournal
Year: 2023

description: This essay proposes a qualitative analysis of a sample of American travel literature on Italy produced between 1948 and 1960. The objective is to unravel the complex interplay between the evolving post-World War II global scenario and the well-entrenched American perceptions of Italy developed over the 19th and 20th centuries. Therefore, the article scrutinizes the narratives’ thematic and ideological shifts in relation to the backdrop of Cold War politics, the Marshall Plan, and Italy’s own transformation into a republic. It investigates how these geopolitical factors influenced the portrayal of Italy in American travel literature and, conversely, how the traditional romanticized image of Italy persisted or evolved. In addition to highlighting to what extent the language and rhetoric of travel literature interacted with the dictates of contemporary contingencies relying deeply on past images and themes, the essay also attempts to offer some insights into the evolution of American self-perception toward Europe by observing travel writings. Sources for this research are travel articles in newspapers and especially American magazines (Holiday and National Geographic) and travel guides published in the United States between 1949 and 1960.

Opening and Closing Gates in Cold War America
Creators: name: Ciulla, Alice
Publisher: name: RSAJournal
Year: 2023

description: This essay examines the manifold impacts of Cold War imperatives on American immigration policy. In the bipolar era, and especially until the peak of détente in the mid-1970s, anticommunism provided the political prerequisite to the restriction of the visa system. There was widespread consensus around the need to exclude foreign radicals in order to preserve the integrity of the nation. At the same time, the willingness of the USA to present itself as a model superior to the Soviet Union was the pretext for opening borders and increasing the entry of refugees, especially from communist regimes. Both these approaches had to face long-existing matters of concern over the national identity, in which race, ethnicity, education, and economic conditions represented crucial factors to select incoming migrants. Focusing on the connections between the Cold War (a multi-faceted era, whose periodization varies according to the perspective adopted) and American immigration policy (which rules the most evident of transnational phenomena), migration offers the chance to rethink both, and provides suggestions for further research on the subject.

description: Supernovae Type Iax (SNe Iax) are less energetic and less luminous than typical thermonuclear explosions. A suggested explanation for the observed characteristics of this subclass is a binary progenitor system consisting of a CO white dwarf primary accreting from a helium star companion. A single-degenerate explosion channel might be expected to result in a dense circumstellar medium (CSM), although no evidence for such a CSM has yet been observed for this subclass. Here we present recent Spitzer observations of the SN Iax 2014dt obtained by the SPIRITS program nearly one year post-explosion that reveal a strong mid-IR excess over the expected fluxes of more normal SNe Ia. This excess is consistent with 1E-5 M_solar of newly formed dust, which would be the first time that newly formed dust has been observed to form in a normal Type Ia. The excess, however, is also consistent with a dusty CSM that was likely formed in pre-explosion mass-loss, thereby suggesting a single degenerate progenitor system. Compared to other SNe Ia that show significant shock interaction (SNe Ia-CSM) and interacting core-collapse events (SNe IIn), this dust shell in SN 2014dt is less massive. We consider the implications that such a pre-existing dust shell has for the progenitor system, including a binary system with a mass donor that is a red giant, a red supergiant, and an asymptotic giant branch star.

Love Is a Thing with Feathers
Creators: name: Romanzi, Valentina
Publisher: name: RSAJournal
Year: 2023

description: Amal El-Mohtar and Max Gladstone’s This Is How You Lose the Time War (2019) follows agents Red and Blue as they move through space and time to fight a seemingly endless war between their respective factions. Written in epistolary form, it traces the evolution of their relationship from enmity to star-crossed love. A mix of poetic language and science fictional prose and tropes, the novella touches upon several issues pertaining to the contemporary reflection on the posthuman. The interpretive framework of this essay hinges on the concepts of metamorphosis and metaphor, deployed to explore how the novella continually updates the subjectivity of its protagonists through a series of contacts and interactions with various kinds of Otherness. The goal of this essay is to show that the ontological value of the protagonists’ selves shapeshifts both through their interaction with each other’s alterity and through their contact with the letters – that is, the metaphorical language of their epistolary exchange. As the missives take ever-different forms according to their chrono-spatial context, their message is absorbed through touch, taste, smell, sight, and other senses, resulting in an embodied assemblage of addresser, message, and addressee that well represents the posthuman pull towards a hybrid subject, in a text that equally eschews the boundaries of genre.

Upscaling a model for the thermally-driven motion of screw dislocations
Creators: name: Hudson, Thomas
Publisher: name: arXiv
Year: 2015
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We formulate and study a stochastic model for the thermally-driven motion of interacting straight screw dislocations in a cylindrical domain with a convex polygonal cross-section. Motion is modelled as a Markov jump process, where waiting times for transitions from state to state are assumed to be exponentially distributed with rates expressed in terms of the potential energy barrier between the states. Assuming the energy of the system is described by a discrete lattice model, a precise asymptotic description of the energy barriers between states is obtained. Through scaling of the various physical constants, two dimensionless parameters are identified which govern the behaviour of the resulting stochastic evolution. In an asymptotic regime where these parameters remain fixed, the process is found to satisfy a Large Deviations Principle. A sufficiently explicit description of the corresponding rate functional is obtained such that the most probable path of the dislocation configuration may be described as the solution of Discrete Dislocation Dynamics with an explicit anisotropic mobility which depends on the underlying lattice structure.

Breaking Bread and Sharing Dreams with the Other-than-human
Creators: name: Fargione, Daniela
Publisher: name: RSAJournal
Year: 2023

description: Lydia Millet’s novels have gained momentum within environmental discourses since they often prove how “looking outside the human is what gives human life its meaning” (Millet). In this article, I analyze How the Dead Dream, the first novel of a trilogy published almost ten years after J.M. Coetzee’s The Lives of Animals (2001), the novella written for the 1997-1998 Tanner Lectures at Princeton University. Millet’s book, I argue, is a direct reply to Coetzee’s invitation to reconsider the place of the human vis-à-vis the other-than-human within the complex framework of posthumanism. This implies a recession of the onto-epistemological and ethical divide among species that saturate popular discourses on extinction. Drawing on material ecocriticism and, especially, on Stacy Alaimo’s research (Exposed, 2016), I investigate and critique different forms of epistemological impermeability, such as the assumed domestic safety, cleanness, and the sovereignty of the (male) Western subjectivity. By tracing the radical transformation of T., the main character in the book and rapacious speculator, I demonstrate how the aesthetic and the ethical intersect in the narration of this story of coevolution and cohabitation.
