Publisher: name: Taylor & Francis
Year: 2023

description:
Interpersonal communication networks serve as a critical source of disaster support, yet their dynamic role in disaster coping remains less explored. Drawing from the literature on resilience organizing and network social capital, the current study investigates how individuals from diverse backgrounds re-construct their interpersonal communication networks in response to an emerging disaster and the impact of such networks on disaster-coping outcomes. Using a community survey of multiethnic residents affected by the 2021 Texas Winter Storm, we found that individuals re-constructed their communication networks by developing more racially heterogeneous and stronger interpersonal ties in response to the disaster, and these patterns varied across major ethnic groups. Moreover, individuals’ preexisting interpersonal communication relations both facilitated and constrained their disaster network reconstruction.

description: Il saggio esamina l’evoluzione dei rapporti tra Italia e Germania all’indomani del 1989-90. E si concentra soprattutto sull’analisi dei fattori che in Italia hanno favorito la diffusione di un inedito euroscetticismo e di antichi pregiudizi anti-tedeschi. Obiettivo del saggio consiste quindi nel verificare se e fino a che punto il venir meno della decennale ‘convergenza strategica’ tra Italia e Germania possa essere messo in relazione con la ridefinizione dei parametri della politica tedesca e il riproporsi di una nuova ‘questione tedesca’.

description:
The pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has impacted the economy, health, and society. Emerging strains are making pandemic management challenging. There is an urge to collect epidemiological, clinical, and physiological data to make an informed decision on mitigation. Advances in the Internet of Things (IoT) and edge computing provide solutions for pandemic management through data collection and intelligent computation. While existing data-driven architectures operate on specific application domains and attempt to automate decision-making, they do not capture the multifaceted interaction among computational models, communication infrastructure, and data. In this article, we survey the existing approaches for pandemic management, including data repositories and contact-tracing applications. We envision a unified pandemic management architecture that leverages the IoT and edge computing paradigms to automate recommendations on vaccine distribution, dynamic lockdown, mobility scheduling, and pandemic trend prediction. We elucidate the data flow among the layers, namely, cloud, edge, and end device layers. Moreover, we address the privacy implications, threats, regulations, and solutions that may be adapted to optimize the utility of health data with security guarantees. The article ends with a discussion of the limitations of the architecture and research directions to enhance its practicality.

description: The statistical distributions of active galactic nuclei (AGN), i.e. accreting supermassive black holes (BHs), in mass, space and time, are controlled by a series of key properties, namely the BH-galaxy scaling relations, Eddington ratio distributions and fraction of active BHs (duty cycle). Shedding light on these properties yields strong constraints on the AGN triggering mechanisms whilst providing a clear baseline to create useful mock catalogues for the planning of large galaxy surveys. We here delineate a robust methodology to create mock AGN catalogs built on top of large N-body dark matter simulations via state-of-the-art semi-empirical models. We show that by using as independent tests the AGN clustering at fixed X-ray luminosity, galaxy stellar mass and BH mass, along with the fraction of AGN in groups and clusters, it is possible to significantly narrow down the choice in the relation between black hole mass and host galaxy stellar mass, the duty cycle, and the average Eddington ratio distribution, delivering well-suited constraints to guide cosmological models for the co-evolution of BHs and galaxies. Avoiding such a step-by-step methodology inevitably leads to strong degeneracies in the final mock catalogs, severely limiting their usefulness in understanding AGN evolution and in survey planning and testing.

description: We report the observation of a novel phenomenon, the self-retracting motion of graphite, in which tiny flakes of graphite, after being displaced to various suspended positions from islands of highly orientated pyrolytic graphite, retract back onto the islands under no external influences. Our repeated probing and observing such flakes of various sizes indicate the existence of a critical size of flakes, approximately 35 micrometer, above which the self-retracting motion does not occur under the operation. This helps to explain the fact that the self-retracting motion of graphite has not been reported, because samples of natural graphite are typical larger than this critical size. In fact, reports of this phenomenon have not been found in the literature for single crystals of any kinds. A model that includes the static and dynamic shear strengths, the van der Waals interaction force, and the edge dangling bond interaction effect, was used to explain the observed phenomenon. These findings may conduce to create nano-electromechanical systems with a wide range of mechanical operating frequency from mega to giga hertzs.

Objective: To quantify the extent to which a standardized pain management order set reduced racial and ethnic inequities in post-cesarean pain evaluation and management. Methods: We conducted a retrospective cohort study to quantify racial and ethnic differences in pain evaluation and management before (July 2014-June 2016) and after implementation of a standardized post-cesarean order set (March 2017-February 2018). Electronic medical records were queried for pain scores >7/10, number of pain assessments, and opioid, nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen doses. Outcomes were grouped into 0 to <24 and 24-48 h postpartum, and stratified by race/ethnicity (Hispanic, non-Hispanic Black [NHB], non-Hispanic White [NHW], Asian, and other), as documented in the electronic health record. Analyses included logistic regression for the categorical outcome of pain score >7 (severe pain), and linear regression, with propensity score adjustment. Main effect and interaction terms were used to calculate the difference-in-difference in pain process and outcome measures between the baseline and follow-up periods. Results: After order set implementation (N=888), severe pain remained more common among NHB patients (% pain scores >7 NHW vs. NHB 0 to <24 h: 22% vs. 33%, p=0.003; 24-48 h: 26% vs. 40%, p<0.001). Among all patients, pain management processes changed after implementation of the order set, with overall fewer assessments, less Opioids, and more nonopioid analgesics. However, racial and ethnic inequities in a number of assessments and in treatment were unchanged (all p for interaction >0.05), with the exception of a modest increase in NSAID doses 24-48 h postpartum for Hispanic patients. Conclusion: A standardized pain management order set reduced overall postpartum opioid use, but did not reduce racial and ethnic disparities in pain evaluation and management. Future work should investigate racial equity-focused education and interventions designed to eliminate disparities in pain management.

description: We consider the distribution of an electric field in YBCO-coated conductors for a situation in which the DC transport current is forced into the copper stabilizer due to a weak link -- a section of the superconducting film with a critical current less than the transport current. The electric field in the metal substrate is also discussed. The results are compared with recent experiments on normal zone propagation in coated conductors for which the substrate and stabilizer are insulated from each other. The potential difference between the substrate and stabilizer, and the electric field in the substrate outside the normal zone can be accounted for by a large screening length in the substrate, comparable to the length of the sample. During a quench, the electric field inside the interface between YBCO and stabilizer, as well as in the buffer layer, can be several orders of magnitude greater than the longitudinal macroscopic electric field inside the normal zone. We speculate on the possibility of using possible microscopic electric discharges caused by this large ($\sim $kV/cm) electric field as a means to detect a quench.

description:
It is documented that Hispanic/Latinx kidney stone formers have inferior health-related quality of life (HRQoL) compared to the general population. We hypothesized that socioeconomic factors drive HRQoL disparities. Specifically, we sought to determine if medical insurance type is associated with HRQoL disparities among Hispanic/Latinx stone formers. This was a prospective cohort observational study of patients with kidney stones across the University of San Diego Health Care System. Patients enrolled from June 2018 to August 2020 completed a validated Wisconsin Stone Quality of Life questionnaire (WISQoL). Patient characteristics and self-reported HRQoL were compared between Hispanic/Latinx and non-Hispanic/Latinx stone formers using MANCOVA and ordinal logistic regression. Matched group comparisons were performed based on age, gender, body mass index, stone symptoms, and insurance type using MACOVA. A total of 270 patients were enrolled (Hispanic/Latinx n = 88; non-Hispanic/Latinx n = 182). Hispanic/Latinx stone formers had higher rates of public insurance at baseline (p < 0.001) with significantly lower HRQoL [social impact (p = 0.007)]. However, a matched cohort comparison demonstrated no differences. On multivariate analysis, private insurance increased the likelihood of having higher HRQoL (OR 2.21, p = 0.021), while stone symptoms (OR = 0.06, p < 0.001) and emergency department visits (OR = 0.04, p = 0.008) decreased chances of higher HRQoL. Ethnicity was not a significant factor in HRQoL scores on multivariate analysis. Our analysis suggests that differences in HRQoL among Hispanic/Latinx stone formers may be primarily driven by socioeconomic factors as opposed to clinical or racial differences. Specifically, source of insurance appears to have significant effect on HRQoL in this ethnic group.

description:
Race is a social construct, commonly used in epidemiologic research to adjust for confounding. However, adjustment of race may mask racial disparities, thereby perpetuating structural racism. We conducted a systematic review of articles published in Epidemiology and American Journal of Epidemiology between 2020 and 2021 to (1) understand how race, ethnicity, and similar social constructs were operationalized, used, and reported; and (2) characterize good and poor practices of utilization and reporting of race data on the basis of the extent to which they reveal or mask systemic racism. Original research articles were considered for full review and data extraction if race data were used in the study analysis. We extracted how race was categorized, used-as a descriptor, confounder, or for effect measure modification (EMM)-and reported if the authors discussed racial disparities and systemic bias-related mechanisms responsible for perpetuating the disparities. Of the 561 articles, 299 had race data available and 192 (34.2%) used race data in analyses. Among the 160 US-based studies, 81 different racial categorizations were used. Race was most often used as a confounder (52%), followed by effect measure modifier (33%), and descriptive variable (12%). Fewer than 1 in 4 articles (22.9%) exhibited good practices (EMM along with discussing disparities and mechanisms), 63.5% of the articles exhibited poor practices (confounding only or not discussing mechanisms), and 13.5% were considered neither poor nor good practices. We discuss implications and provide 13 recommendations for operationalization, utilization, and reporting of race in epidemiologic and public health research.

IMPORTANCE: The lack of a reliable method to accurately detect when replication-competent HIV has been cleared is a major challenge in developing a cure. This study introduces a new approach called the HIVepsilon-seq (HIVε-seq) assay, which uses long-read sequencing technology and bioinformatics to scrutinize the HIV genome at the nucleotide level, distinguishing between defective and intact HIV. This study included 30 participants on antiretroviral therapy, including 17 women, and was able to discriminate between defective and genetically intact viruses at the single DNA strand level. The HIVε-seq assay is an improvement over previous methods, as it requires minimal sample, less specialized lab equipment, and offers a shorter turnaround time. The HIVε-seq assay offers a promising new tool for researchers to measure the intact HIV reservoir, advancing efforts towards finding a cure for this devastating disease.
Hearing the shape of a Dirac drum: Dual quantum Hall states on curved surfaces

description: The geometry of a physical system is intimately related to its spectral properties, a concept colloquially referred to as "hearing the shape of a drum". Three-dimensional topological insulator nanowires in a strong magnetic field B generally host Dirac-type quantum Hall (QH) surface states. The surface itself is shaped by spatial variations of the wires' cross section, yielding a curved geometrical background, the "drum", with imprints in the corresponding QH spectra. We show that the latter are composed of two different classes. The first one is asymptotically insensitive to the surface shape, scaling as B^{1/2}, like regular planar QH states. Instead, the second has an asymptotic B-field dependence intimately related to the wire geometry. We further demonstrate that an (axial-symmetric) curved nanowire surface possesses a reciprocal partner surface, such that the respective QH spectra are dual to each other upon exchanging angular momentum and magnetic flux. Notably, a cone-shaped nanowire, and the Corbino geometry as its limiting case, has a reciprocal partner with a dual QH spectrum that is B-field independent, with corresponding non-magnetic QH-type states. We support our analytical findings by numerical results for B-field ranges and wire geometries within reach of current experiment.
Social anxiety and memory deficit for information about others
Creators: name: Biggs, Edward Eugene
Publisher: name: University of British Columbia
Year: 2010

description: Cognitive factors have been identified as critical variables in the origin and maintenance of interpersonal dysfunction associated with high social anxiety. Although evidence of a memory deficit accompanying general anxiety states is abundant, studies of memory accompanying social anxiety have failed to demonstrate a deficit. Previous studies of memory deficit in social anxiety have measured only retention of evaluative feedback, the present study investigated memory more typical of interpersonal encounters, the recall of information about others. Forty-eight high socially anxious males and forty-eight low anxious males were asked to listen to a tape recording of self-disclosures either during an interaction with the self-discloser or in private. Following an interim task, each subject was then asked to recall the information from the tape either in the presence of the female self-discloser or in private. This design allowed for social anxiety provoking manipulation at encoding to be completely crossed with social anxiety manipulation at retrieval. Multiple measures of memory were taken and analyzed with a multivariate procedure. It was hypothesized that a situational deficit would occur for the high socially anxious subjects when they were encoding the other-referent information in a social context. Additionally, it was hypothesized that high socially anxious subjects would recall more affective as opposed to neutral information, and more negative items than positive or neutral. The results confirmed that memory is disturbed for high socially anxious subjects when in a social context, and specifically the disturbance occurs at the encoding phase. Results regarding the recall of affective material were contrary to prediction and suggest that high socially anxious subjects selectively process less affective material than do low socially anxious subjects. The results are supportive of a cognitive perspective arguing that dysfunctional interpersonal experiences may stem from impoverished, incomplete, and barren schema that guide the social behavior. The presence of a recall deficit along with intact recognition memory suggests that information about others is attended to but not processed 'deeply' or elaborately enough to be available on a free recall basis. The identification of memory deficit as a component of social anxiety provides a variety of new intervention possibilities including social memory enhancement programs, interventions aimed at unearthing poorly encoded memories, and strategies focused on attention to affective messages.

description: We examine the correspondence between the anti-de Sitter (AdS) description of conformal field theories (CFTs) and the unparticle description of CFTs. We show how unparticle actions are equivalent to holographic boundary actions for fields in AdS, and how massive unparticles provide a new type of infrared cutoff that can be simply implemented in AdS by a soft breaking of conformal symmetry. We also show that processes involving scalar unparticles with dimensions d_s<2 or fermion unparticles with dimensions d_f<5/2 are insensitive to ultraviolet cutoff effects. Finally we show that gauge interactions for unparticles can be described by bulk gauge interactions in AdS and that they correspond to minimal gauging of the non-local effective action, and we compute the fermion unparticle production cross-section.

Describing future eventualities in Tlingit
Creators: name: Cable, Seth
Publisher: name: Semantic Fieldwork Methods
Year: 2019

description: This paper details two storyboards —"Hawaii Trip" and "Imagining the Future"—which are designed to help investigate the way a given language does (or does not) mark predicates describing eventualities that take place in the future. I describe two studies employing these storyboards with a speaker of the Tlingit language (Na-Dene; Alaska, British Columbia, Yukon). In prior literature, it has been claimed that a verb in Tlingit does not require special future tense marking in order to describe a future eventuality (Leer 1991). However, it has proven difficult to confirm such uses of non-future-marked verbs in regular elicitation sessions with native speakers.  Through use of these two storyboards with a gifted Tlingit story-teller, it was found that some narrators do indeed use non-future-marked verbs to describe eventualities that are understood to take place in the future. However, various contextual clues—including metalinguistic comments made by the narrator himself—-suggest that such usage may reflect a special narrative or rhetorical device, akin to 'narrative present' in English. Consequently, it appears that the regular grammar of the language does require future tense marking when describing future eventualities, but artful narrators can in the course of the narrative 'shift' the temporal perspective of the narration to the future time in question, presenting those future events as on-going. While much more work must be done to rigorously test this hypothesis, these case studies nicely illustrate the use and utility of these fieldwork instruments.

description:
Migration across the Americas is an ever-changing process with current trends including increased migration into the United States of Latine youth. Experiences before, during, and after migration can increase the risk of psychiatric illness, including discriminatory and exclusionary experiences when accessing care. Acculturation typically focuses on the process that the immigrant group experiences when coming into contact with a host culture. Members of the host culture and systems of care can take intentional steps to acculturate themselves in an integrative manner in an effort to reduce host-immigrant friction and better coordinate care across systems.

description: Calculations of the evolution of cosmological perturbations generally involve solution of a large number of coupled differential equations to describe the evolution of the multipole moments of the distribution of photon intensities and polarization. However, this "Boltzmann hierarchy" communicates with the rest of the system of equations for the other perturbation variables only through the photon-intensity quadrupole moment. Here I develop an alternative formulation wherein this photon-intensity quadrupole is obtained via solution of two coupled integral equations -- one for the intensity quadrupole and another for the linear-polarization quadrupole -- rather than the full Boltzmann hierarchy. This alternative method of calculation provides some physical insight and a cross-check for the traditional approach. I describe a simple and efficient iterative numerical solution that converges fairly quickly. I surmise that this may allow current state-of-the-art cosmological-perturbation codes to be accelerated.

description: The thermal chiral anomaly is a new mechanism for thermal transport that occurs in Weyl semimetals (WSM). It is attributed to the generation and annihilation of energy at Weyl points of opposite chirality. The effect was observed in the Bi1-xSbx alloy system, at x=11% and 15%, which are topological insulators at zero field and driven into an ideal WSM phase by an external field. Given that the experimental uncertainty on x is of the order of 1%, any systematic study of the effect over a wider range of x requires precise knowledge of the transition composition xc at which the electronic bands at the L-point in these alloys have Dirac-like dispersions. At x>xc, the L-point bands are inverted and become topologically non-trivial. In the presence of a magnetic field along the trigonal direction, these alloys become WSMs. This paper describes how the temperature dependence of the frequency of the Shubnikov-de Haas oscillations F(x,T) at temperatures of the order of the cyclotron energy can be used to find xc and characterize the topology of the electronic Fermi surface. Alloys with topologically trivial bands have dF(x,T)/dT>0, those with Dirac/Weyl fermions display dF(x,T)/dT<0.

description: Chirp can control the dynamics of the Airy pulse, making it an essential factor in pulse manipulation. Finite energy chirped Airy pulse (FECAP) has potential applications in underwater optical communication and imaging. Hence, it's critical to study the propagation of FECAP. We present a numerical investigation of the propagation dynamics of a FECAP in a dispersive, and highly nonlinear medium. The nonlinearity under study includes self-phase modulation (SPM), self-steepening (SS), as well as intra-pulse Raman scattering (IRS) terms. We have observed soliton shedding and the chirp parameter is demonstrated to have a considerable impact on the pulse dynamics. In particular, the emergent soliton does not propagate in a straight path instead, depending on the sign of the chirp parameter, it delays or advances in the time. Furthermore, it has been established that the chirp can be employed as an alternate control parameter for the spectral manipulation. The results of our study may have implications in supercontinuum generation and for producing tunable sources.

We demonstrate that atom interferometers using such condensates are robust against phase fluctuations, i.e. the relative phase of the split condensate is reproducible despite axial phase fluctuations. However, larger phase fluctuations limit the coherence time, especially in the presence of some asymmetries in the two wells of the interferometer.

description: In this paper, we prove that a normal subgroup N of an n-dimensional crystallographic group G determines a geometric fibered orbifold structure on the flat orbifold E^n/G, and conversely every geometric fibered orbifold structure on E^n/G is determined by a normal subgroup N of G, which is maximal in its commensurability class of normal subgroups of G. In particular, we prove that E^n/G is a fiber bundle, with totally geodesic fibers, over a b-dimensional torus, where b is the first Betti number of G. Let N be a normal subgroup of G which is maximal in its commensurability class. We study the relationship between the exact sequence 1 -> N -> G -> G/N -> 1 splitting and the corresponding fibration projection having an affine section. If N is torsion-free, we prove that the exact sequence splits if and only if the fibration projection has an affine section. If the generic fiber F = Span(N)/N has an ordinary point that is fixed by every isometry of F, we prove that the exact sequence always splits. Finally, we describe all the geometric fibrations of the orbit spaces of all 2- and 3-dimensional crystallographic groups building on the work of Conway and Thurston.

description: We show that the singular holomorphic foliations induced by dominant quasi-homogeneous rational maps fill out irreducible components of the space $\mathscr F_q(r, d)$ of singular foliations of codimension $q$ and degree $d$ on the complex projective space $\mathbb P^r$, when $1\le q \le r-2$. We study the geometry of these irreducible components. In particular we prove that they are all rational varieties and we compute their projective degrees in several cases.

description: String theory realisations of the QCD axion are often said to belong to the anthropic window where the decay constant is around the GUT scale and the initial misalignment angle has to be tuned close to zero. In this paper we revisit this statement by studying the statistics of axion physics in the string landscape. We take moduli stabilisation properly into account since the stabilisation of the saxions is crucial to determine the physical properties of the corresponding axionic partners. We focus on the model-independent case of closed string axions in type IIB flux compactifications and find that their decay constants and mass spectrum feature a logarithmic, instead of a power-law, distribution. In the regime where the effective field theory is under control, most of these closed string axions are ultra-light axion-like particles, while axions associated to blow-up modes can naturally play the role of the QCD axion. Hence, the number of type IIB flux vacua with a closed string QCD axion with an intermediate scale decay constant and a natural value of the misalignment angle is only logarithmically suppressed. In a recent paper we found that this correlates also with a logarithmic distribution of the supersymmetry breaking scale, providing the intriguing indication that most, if not all, of the phenomenologically interesting quantities in the string landscape might feature a logarithmic distribution.

description: We discuss the inverse problem of determining the, possibly anisotropic, conductivity of a body $Ω\subset\mathbb{R}^{n}$ when the so--called Dirichlet-to-Neumann map is locally given on a non empty portion $Γ$ of the boundary $\partialΩ$. We extend results of uniqueness and stability at the boundary, obtained by the same authors in SIAM J. Math. Anal. 33 (2001), no. 1, 153--171, where the Dirichlet-to-Neumann map was given on all of $\partialΩ$ instead. We also obtain a pointwise stability result at the boundary among the class of conductivities which are continuous at some point $y\inΓ$. Our arguments also apply when the local Neumann-to-Dirichlet map is available.

description: The theory of remote sensing shows that observing a planet at multiple phase angles ($α$) is a powerful strategy to characterize its atmosphere. Here, we analyse how the information contained in reflected-starlight spectra of exoplanets depends on the phase angle, and the potential of multi-phase measurements to better constrain the atmospheric properties and the planet radius ($R_p$). We simulate spectra (500-900 nm) at $α$=37$^\circ$, 85$^\circ$ and 123$^\circ$ with spectral resolution $R$~125-225 and signal-to-noise ratio $S/N$=10. Assuming a H$_2$-He atmosphere, we use a seven-parameter model that includes the atmospheric methane abundance ($f_{CH_4}$), the optical properties of a cloud layer and $R_p$. All these parameters are assumed unknown a priori and explored with an MCMC retrieval method. We find that no single-phase observation can robustly identify whether the atmosphere has clouds or not. A single-phase observation at $α$=123$^\circ$ and $S/N$=10 can constrain $R_p$ with a maximum error of 35%, regardless of the cloud coverage. Combining small (37$^\circ$) and large (123$^\circ$) phase angles is a generally effective strategy to break multiple parameter degeneracies. This enables to determine the presence or absence of a cloud and its main properties, $f_{CH_4}$ and $R_p$ in all the explored scenarios. Other strategies, such as doubling $S/N$ to 20 for a single-phase observation or combining small (37$^\circ$) and moderate (85$^\circ$) phase angles, fail to achieve this. We show that the improvements in multi-phase retrievals are associated with the shape of the scattering phase function of the cloud aerosols and that the improvement is more modest for isotropically-scattering aerosols. We finally discuss that misidentifying the background gas in the retrievals of super-Earth observations leads to a systematic underestimate of the absorbing gas abundance.

description: For a stopped diffusion process in a multidimensional time-dependent domain $\D$, we propose and analyse a new procedure consisting in simulating the process with an Euler scheme with step size $Δ$ and stopping it at discrete times $(iΔ)_{i\in\N^*}$ in a modified domain, whose boundary has been appropriately shifted. The shift is locally in the direction of the inward normal $n(t,x)$ at any point $(t,x)$ on the parabolic boundary of $\D$, and its amplitude is equal to $0.5826 (...) |n^*σ|(t,x)\sqrt Δ$ where $σ$ stands for the diffusion coefficient of the process. The procedure is thus extremely easy to use. In addition, we prove that the rate of convergence w.r.t. $Δ$ for the associated weak error is higher than without shifting, generalizin g previous results by \cite{broa:glas:kou:97} obtained for the one dimensional Brownian motion. For this, we establish in full generality the asymptotics of the triplet exit time/exit position/overshoot for the discretely stopped Euler scheme. Here, the overshoot means the distance to the boundary of the process when it exits the domain. Numerical experiments support these results.

description: We assemble a sample of 17 low metallicity (7.45 < log(O/H)+12 < 8.12) galaxies with z < 0.1 found spectroscopically, without photometric pre-selection, in early data from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX). Star forming galaxies that occupy the lowest mass and metallicity end of the mass-metallicity relation tend to be under sampled in continuum-based surveys as their spectra are typically dominated by emission from newly forming stars. We search for galaxies with high [OIII]$λ$5007 / [OII]$λ$3727, implying highly ionized nebular emission often indicative of low metallicity systems. With the Second Generation Low Resolution Spectrograph on the Hobby Eberly Telescope we acquired follow-up spectra, with higher resolution and broader wavelength coverage, of each low-metallicity candidate in order to confirm the redshift, measure the H$α$ and [NII] line strengths and, in many cases, obtain deeper spectra of the blue lines. We find our galaxies are consistent with the mass-metallicity relation of typical low mass galaxies. However, galaxies in our sample tend to have similar specific star formation rates (sSFRs) as the incredibly rare "blueberry" galaxies found in (Yang et. al. 2017). We illustrate the power of spectroscopic surveys for finding low mass and metallicity galaxies and reveal that we find a sample of galaxies that are a hybrid between the properties of typical dwarf galaxies and the more extreme blueberry galaxies.

An exploration of the use of metaphor in effective counselling

description: The purpose of this study is to explore the use of metaphor in effective counselling. A single case study approach was adopted for the research. The material of a family in therapy by Virginia Satir as therapist was transcribed verbatim from the audio tapes. The metaphors of both the therapist and the client were identified from the transcript. They were then classified according to their types and the processes involved. Next the patterns of metaphoric usage were examined. The movement in counselling was measured using a special scale. Points of significant movement in the client were identified. The correspondence of the uses of the metaphors and the client's progress was studied. Forty-five instances of the use of metaphors by the therapist were reported. But metaphors were used by the client only five times. The most significant metaphors used by the therapist all occurred at points where there were a lot of progress in the counselling. The overall analysis demonstrated the usefulness of the concepts of metaphors used for this research. It also illustrated the fact that metaphors can be the direct vehicle of insights that contribute towards effective counselling. Insights from the metaphors were not dependent on the ability of the client to reciprocate in metaphoric expression. Some implications for the practice of counselling using metaphors were suggested and some recommendations for future research were offered.
