description: Chronic kidney disease (CKD) is a significant public health problem. Environmental factors may impact the development and progression of CKD; however, neither the factors related to progression nor the mechanisms of action have been well elucidated. Our aim was to examine the associations among measured levels of endogenous hormones, persistent organic pollutants (POPs), and parameters of kidney function using cross-sectional and longitudinal data from the National Health and Nutrition Examination Survey (NHANES) and the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Two of our analyses evaluated the cross-sectional and prospective associations of endogenous levels of pituitary, sex-steroid, and thyroid hormones with measures of kidney health within a cohort of Hispanic and Latino adults. We showed that circulating levels of thyroid stimulating hormone (TSH) were inversely associated with estimated glomerular filtration rate (eGFR) and positively associated with incident albuminuria. Among post-menopausal females, luteinizing hormone (LH) and follicle stimulating hormone (FSH) concentrations were inversely associated with eGFR cross-sectionally and LH was inversely associated with odds of incident albuminuria. Among males, LH was inversely associated with eGFR and positively associated with urinary albumin to creatinine ratio (UACR) and odds of albuminuria at baseline, but longitudinal associations were not significant. Among males, free testosterone was inversely associated with UACR cross-sectionally, and total testosterone was inversely associated eGFR longitudinally. We then evaluated the cross-sectional and prospective associations of POPs with measures of kidney health using the HCHS/SOL data. Polychlorinated biphenyl (PCB) concentrations were associated with small increases in UACR over time. Concentrations of 1,1-dichloro-2,2-bis(4-chlorophenyl)-ethene (DDE) were associated with lower levels of UACR over time. When we used cross-sectional data from the NHANES, we found that PCB concentrations were positively associated with eGFR and UACR among males, and concentrations of heptachlor epoxide were associated with increased odds of low eGFR among both sexes. Future investigation of these data will include interaction and mediation analyses. Our results require further validation and reproduction in additional cohorts but suggest that POPs and endogenous hormones are involved in the pathology of CKD.

description: Abstract: Background: Improving openness—including candour when things go wrong, and willingness to learn from mistakes—is increasingly seen as a priority in many healthcare systems. This study explores perceptions of openness in England before and after the publication of the Francis report (2013), which examined failings of openness at one English hospital. We examine whether staff and patients’ views on openness, and experiences of giving voice to concerns, have changed since the report’s publication for better or worse. Methods: Organisational-level data was collated for all trusts from the NHS National Staff Survey (2007–2017), NHS Acute Inpatient Survey (2004–2016) and NHS Community Mental Health Service User Survey (2007–2017). Survey items related to openness were identified and longitudinal statistical analysis conducted (piecewise growth curve and interrupted latent growth curve analysis) to determine whether there was evidence of a shift in the rate or direction of change following publication of the Francis report. Results: For some variables there was a discernible change in trajectory after the publication of the Francis report. Staff survey variables continued to rise after 2013, with a statistically significant increase in rate for “fairness and effectiveness of incident reporting procedures” (from + 0.02 to + 0.06 per year; p < .001). For the patient surveys, the picture was more mixed: patient views about information provided by accident and emergency staff rose from a 0.3% increase per year before 2013 to 0.8% per year afterwards (p < .01), and inpatients being involved in decision making increased from a 0.4% rise per year before 2013 to 0.8% per year afterwards (p < .01); however, there were not rises in the other questions. Mental health patients reported a decrease after 2013 in being listened to (decreasing at a rate of 1.9% per year, p < .001). Conclusions: Data suggest that the Francis inquiry may have had a positive impact on staff and acute inpatients’ perceptions and experiences of openness in the NHS. However such improvements have not transpired in mental health. How best to create an environment in which patients can discuss their care and raise concerns openly in mental health settings may require further consideration.

description: This study aimed to establish a method for the extraction, enrichment, and identification of volatile organic compounds (VOCs) released by the flowers of purple (BRS 399) and white (DONMARIO 6563) soybean varieties. We tested the Static Headspace (HS) and Solid Phase Microextraction (SPME) methods using various fibre types: PDMS (Polydimethylsiloxane), PDMS/DVB (Divinylbenzene), and PDMS/DVB/CAR (Carboxen). We employed gas chromatography–mass spectrometry (GC–MS) to identify the VOCs. The SPME method with PDMS/DVB and PDMS/DVB/CAR fibres yielded the highest number of extracted compounds for both soybean cultivars. Notably, 67 compounds were detected in Glycine max. L for the first time. Using the developed method, we were able to detect 52 and 57 VOCs in the purple and white soybean varieties, respectively, including ketones, alcohols, aldehydes and benzenoids. In conclusion, the method we developed effectively identified VOCs in soybean flowers, thus enriching our understanding of the interactions between soybean flowers and their pollinators.

description: The ever-expanding availability of reproductive technologies, the continued roll-out of 'family planning' and maternity services across low- and middle-income settings and the rapid development of the fertility industry mean that it is more likely than ever that individuals, especially women and gender non-conforming people, will engage with more than one RT at some point in their life. These multiple engagements with RTs will affect users' expectations and uptake, as well as the technologies' availability, commercial success, ethical status and social meanings. We argue that an integrated approach to the study of RTs and their users not only makes for better research, but also more politically conscious research, which questions some of the ideological precepts that have led to reproduction being parcelled out into biomedical specialisations and a disproportionate focus on particular forms of reproduction in particular disciplines within public health and social science research. We offer this article as part of a wider movement in the study of reproduction and reproductive technologies, which takes inspiration from the reproductive justice framework to address forms of exclusion, discrimination and stratification that are perpetuated in the development and application of reproductive technologies and the ways in which they are studied and theorised.

description: Periodontitis is an infectious, inflammatory, multifactorial disease characterized by irreversible loss of supporting tissues of teeth. While, significant progress has been made in elucidating mechanisms associated with periodontal inflammation and resolution, very little is known regarding role of miRNAs in this process. Upon miRNA array analysis from the 100 differentially expressed miRNAs in periodontal disease, a subset of miRNAs were responsive to therapy in achieving levels as compared to those of healthy specimens. These were predicted to regulate inflammatory pathways related to cell movement, cytokine signaling, ECM re-organization, immune cell development, etc. Functional analysis identified therapy responsive miRs implicated in mechanisms impacting cellular architecture and periodontal-pathogen induced inflammatory response in gingival epithelial cells & macrophages. Given that clinical and radiologic determinants of periodontal disease like Probing Depth, irreversible bone loss are measured retrospectively, identification for accurate biomarkers in the diagnosis of periodontitis, at earlier inflammatory stage of the disease is paramount. Characterization of miRNA as potential biomarkers for early detection of periodontitis can prove to be greatly effective for diagnosis and management of oral diseases. Application of miRNA genomic and proteomic technologies may prove beneficial during course of periodontal therapy.

description: In the faint star KIC 9700322 observed by the Kepler satellite, 76 frequencies with amplitudes from 14 to 29000 ppm were detected. The two dominant frequencies at 9.79 and 12.57 c/d (113.3 and 145.5 μHz), interpreted to be radial modes, are accompanied by a large number of combination frequencies. A small additional modulation with a 0.16 c/d frequency is also seen; this is interpreted to be the rotation frequency of the star. The corresponding prediction of slow rotation is confirmed by a spectrum from which v sin i = 19 \pm 1 km/s is obtained. The analysis of the spectrum shows that the star is one of the coolest δ Sct variables. We also determine Teff = 6700 \pm 100 K and log g = 3.7 \pm 0.1, compatible with the observed frequencies of the radial modes. Normal solar abundances are found. An \ell = 2 frequency quintuplet is also detected with a frequency separation consistent with predictions from the measured rotation rate. A remarkable result is the absence of additional independent frequencies down to an amplitude limit near 14 ppm, suggesting that the star is stable against most forms of nonradial pulsation. The frequency spectrum of this star emphasizes the need for caution in interpreting low frequencies in δ Sct stars as independent gravity modes. A low frequency peak at 2.7763 c/d in KIC 9700322 is, in fact, the frequency difference between the two dominant modes and is repeated over and over in various frequency combinations involving the two dominant modes. The relative phases of the combination frequencies show a strong correlation with frequency, but the physical significance of this result is not clear.

description: We present Subaru/Suprime-Cam deep V and I imaging of seven fields in the outer regions of M33. Our aim is to search for stellar structures corresponding to extended HI clouds found in a recent 21-cm survey of the galaxy. Three fields probe a large HI complex to the southeastern (SE) side of the galaxy. An additional three fields cover the northwestern (NW) side of the galaxy along the HI warp. A final target field was chosen further north, at a projected distance of approximately 25 kpc, to study part of the large stellar plume recently discovered around M33. We analyse the stellar population at R > 10 kpc by means of V, I colour magnitude diagrams reaching the red clump. Evolved stellar populations are found in all fields out to 120' (~ 30 kpc), while a diffuse population of young stars (~ 200 Myr) is detected out to a galactocentric radius of 15 kpc. The mean metallicity in the southern fields remains approximately constant at [M/H] = -0.7 beyond the edge of the optical disc, from 40' out to 80'. Along the northern fields probing the outer \hi disc, we also find a metallicity of [M/H] = -0.7 between 35' and 70' from the centre, which decreases to [M/H] = -1.0 at larger angular radii out to 120'. In the northernmost field, outside the disc extent, the stellar population of the large stellar feature possibly related to a M33-M31 interaction is on average more metal-poor ([M/H] = -1.3) and older (> 6 Gyr). An exponential disc with a large scale-length (~ 7 kpc) fits well the average distribution of stars detected in both the SE and NW regions from a galactocentric distance of 11 kpc out to 30 kpc. The stellar distribution at large radii is disturbed and, although there is no clear correlation between the stellar substructures and the location of the HI clouds, this gives evidence for tidal interaction or accretion events.

description: We study the breaking of an Abelian symmetry close to the horizon of an uncharged rotating Anti-de Sitter black string in 3+1 dimensions. The boundary theory living on R^2 x S^1 has no rotation, but a magnetic field that is aligned with the axis of the black string. This boundary theory decribes non-rotating (2+1)-dimensional holographic superfluids with non-vanishing superfluid velocity. We study these superfluids in the grand canonical ensemble and show that for sufficiently small angular momentum of the dual black string and sufficiently small superfluid velocity the phase transition is 2nd order, while it becomes 1st order for larger superfluid velocity. Moreover, we observe that the phase transition is always 1st order above a critical value of the angular momentum independent of the choice of the superfluid velocity.

description: Abstract: Systemic insecticides such as neonicotinoids are widely used in seed coating practices for pest control in many crops, e.g., corn. Their success is due to their ability to protect the whole plant, from the roots to the upper leaves, but their use at high amounts is causing possible adverse effects on non-target animals exposed to contaminated pollen, nectar, leaves, and dust emitted during sowing. In 2018, the European Union banned some neonicotinoids and fipronil as seed coating insecticides in open fields. Consequently, the methylcarbamate methiocarb and less-toxic neonicotinoids, e.g., thiacloprid, have been authorized and largely used as alternative pesticides for corn seed coating. Here, an analytical protocol based on QuEChERS extraction/purification procedure and analysis by liquid chromatography-mass spectrometry has been optimized for the identification and the quantification of methiocarb, thiamethoxam, thiacloprid, and their metabolites in guttation drops, the xylem fluid excreted at leaf margins, and in leaves of corn plants grown from coated seeds. Although methiocarb is a non-systemic pesticide, we unexpectedly found high concentrations of its metabolites in both guttations and leaves, whereas methiocarb itself was below detection limits in most of the samples. The methiocarb main metabolite, methiocarb sulfoxide, was found at a mean concentration of 0.61 ± 1.12 µg mL−1 in guttation drops and 4.4 ± 2.1 µg g−1 in leaves. Conversely, parent compounds of neonicotinoids (thiamethoxam, thiacloprid) are systemically distributed in corn seedlings. This result raises safety concerns given that methiocarb sulfoxide is more toxic than the parent compound for some non-target species.

description: We consider the relation of symmetries and subspace controllability for spin networks with XXZ coupling subject to control of a single node by a local potential (Z-control). Such networks decompose into excitation subspaces. Focusing on the single excitation subspace it is shown that for single-node Z-controls external symmetries are characterized by eigenstates of the system Hamiltonian that have zero overlap with the control node, and there are no internal symmetries. It is further shown that there are symmetries that persist even in the presence of random perturbations. For uniformly coupled XXZ chains a characterization of all possible symmetries is given, which shows a strong dependence on the position of the node we control. Finally, it is shown rigorously for uniform Heisenberg and XX chains subject to single-node Z-control that the lack of symmetry is not only necessary but sufficient for subspace controllability. The latter approach is then generalized to establish controllability results for simple branched networks.

Platelet factor 4 upregulates matrix metalloproteinase-1 production in gingival fibroblasts
Creators: name: Javaid, Mohammad
Publisher: name: University of British Columbia
Year: 2017

description: Background and Objective: Periodontitis is a highly prevalent chronic inflammatory disease that causes tooth loss, morbidity and confers an increased risk for systemic disease. Tissue destruction during periodontitis is due in large part to collagen-degrading matrix metalloproteinases (MMPs) released by resident cells of the periodontium in response to pro-inflammatory cytokines. Platelets are immune-competent blood cells with a newly recognized role in chronic inflammation, however their role in the pathogenesis of periodontitis is undefined. Consequently, the objective of this study was to assess the effect of platelet factor 4 (PF4), a major platelet-derived cytokine, on MMP-1 (collagenase) expression in human gingival fibroblasts (HGFs). Methods: HGFs were cultured in the presence or absence of recombinant PF4. Pro-MMP-1 secretion was quantified by enzyme-linked immunosorbent assay (ELISA) analysis of the cell culture supernatants. MMP-1 transcription was quantified by real-time polymerase chain reaction (qPCR). Regulation of MMP-1 production by the p44/42 MAP kinase (MAPK) signaling pathway was examined in the presence or absence of PF4. Results: Exposure to PF4 caused a ~2-3-fold increase in MMP-1 transcription and secretion from cultured human gingival fibroblasts (HGFs). PF4 treatment also enhanced phosphorylation of p44/42 MAP kinase (MAPK), which has been previously shown to induce MMP-1 expression in fibroblasts. Blockade of p44/42 MAPK signaling with the cell-permeant inhibitors PD98059 and PD184352 abrogated PF4-induced pro-MMP-1 transcription upregulation and release from cultured HGFs. Conclusion: We conclude that platelet factor 4 upregulates MMP-1 expression in human gingival fibroblasts in a p44/42 MAPK-dependent manner. These findings point to a previously unidentified role for platelets in the pathogenesis of periodontal diseases.

description: Objective: To understand the self-perceived preparedness of graduating students and graduates of Nigerian medical and dental schools for their roles as interns. Methods: A cross sectional survey of graduating students and interns, assessing their self-reported preparedness for the role of interns before internship and their actual experiences at internship. Survey instruments explored respondents’ demographics, understanding of the roles of interns, self-reported preparedness for internship, and self-assessed competence at internship. Data was analyzed using descriptive statistics. Mean, standard deviation, median, and Chi Square test were employed in interpreting results. Ordinal survey responses were converted to means(SD), student’s t test was employed in determining statistical significance. Significance was inferred at p value less than 0.05. Results: There were 1,798 respondents (291 graduating students and 1,507 interns) who trained from all the accredited medical and dental schools in Nigeria. Subjects demonstrated a good knowledge of an intern’s expected role but with some inconsistencies. On a six-point scale, their overall self-perceived preparedness for routine general clinical task ranged from 4.63(1.17) to 5.06(1.12). On a 4-point scale, graduating dental students and interns’ overall self-perceived preparedness for specific tasks ranged from 2.12(0.82) to 3.86(0.35), while graduating medical students and interns reported mean(SD) 3.3(0.71) and 2.9(0.88) respectively. Self-perceived unpreparedness featured majorly around basic medical and dental clinical skills, as well as some medical specialty related skills (mean(SD) of 2.2(0.9) to 3.0(0.9) on a 5-point scale. Ward round was rated most helpful in preparing medical interns for their roles, while dental students rated lectures in basic and clinical sciences similarly. Conclusion: Subjects demonstrated a fair knowledge of an intern’s expected roles with a degree of inconsistency. Self-perceived preparedness shows deficiencies with basic clinical skills but preparedness in history taking and physical examination. There is a need to direct trainees’ attention from meeting clinical requirement/eligibility for examination, to acquiring excellent clinical skills. The need for transitional programs at the beginning of clinical years and before internship is apparent. These findings have implications for prompt curriculum review and a variety of audits in the training programs.

description: Abstract: The occurrence of superconductivity in doped SrTiO3 at low carrier densities points to the presence of an unusually strong pairing interaction that has eluded understanding for several decades. We report experimental results showing the pressure dependence of the superconducting transition temperature, Tc, near to optimal doping that sheds light on the nature of this interaction. We find that Tc increases dramatically when the energy gap of the ferroelectric critical modes is suppressed, i.e., as the ferroelectric quantum critical point is approached in a way reminiscent to behaviour observed in magnetic counterparts. However, in contrast to the latter, the coupling of the carriers to the critical modes in ferroelectrics is predicted to be small. We present a quantitative model involving the dynamical screening of the Coulomb interaction and show that an enhancement of Tc near to a ferroelectric quantum critical point can arise due to the virtual exchange of longitudinal hybrid-polar-modes, even in the absence of a strong coupling to the transverse critical modes.

description: This paper examines how to compare stellar limb-darkening coefficients evaluated from model atmospheres with those derived from photometry. Different characterizations of a given model atmosphere can give quite different numerical results (even for a given limb-darkening `law'), while light-curve analyses yield limb-darkening coefficients that are dependent on system geometry, and that are not directly comparable to any model-atmosphere representation. These issues are examined in the context of exoplanetary transits, which offer significant advantages over traditional binary-star eclipsing systems in the study of stellar limb darkening. `Like for like' comparisons between light-curve analyses and new model-atmosphere results, mediated by synthetic photometry, are conducted for a small sample of stars. Agreement between the resulting synthetic-photometry/atmosphere-model (SPAM) limb-darkening coefficients and empirical values ranges from very good to quite poor, even though the targets investigated show only a small dispersion in fundamental stellar parameters.

description: Pecan nuts (Carya illinoinensis (Wangenh.) K. Koch) contain the highest number of phytochemicals of all nuts, are a natural source of unsaturated fatty acids and other nutrients and can be considered an important addition to the Mediterranean diet al.though several studies have been carried out on pecans, employing several analytical techniques, no systematic study of the metabolic profile is available in literature. In this study, the metabolic profile of pecan nuts of three different cultivars was analysed by Nuclear Magnetic Resonance Spectroscopy. The cultivars compared were Wichita, Stuart, and Sioux, all grown in Italy in the same pedoclimatic conditions. 31 metabolites were identified and 28 were quantified and the three species were differentiated based on multivariate PCA analysis. The differences among them, and the levels of scutellarein and GABA, in particular, were attributed to the adaptation of the plants to the climate in their original areas.

description: By using the full density matrix approach to spectral functions within the numerical renormalization group method, we present a detailed study of the magnetic field induced splittings in the spin-resolved and the total spectral densities of a Kondo correlated quantum dot described by the single level Anderson impurity model. The universal scaling of the splittings with magnetic field is examined by varying the Kondo scale either by a change of local level position at a fixed tunnel coupling or by a change of the tunnel coupling at a fixed level position. We find that the Kondo-peak splitting $Δ/T_K$ in the spin-resolved spectral function always scales perfectly for magnetic fields $B<8T_K$ in either of the two $T_K$-adjusted paths. Scaling is destroyed for fields $B>10T_K$. On the other hand, the Kondo peak splitting $δ/T_K$ in the total spectral function does slightly deviate from the conventional scaling theory in whole magnetic field window along the coupling-varying path. Furthermore, we show the scaling analysis suitable for all field windows within the Kondo regime and two specific fitting scaling curves are given from which certain detailed features at low field are derived. In addition, the scaling dimensionless quantity $Δ/2B$ and $δ/2B$ are also studied and they can reach and exceed 1 in the large magnetic field region, in agreement with a recent experiment [T.M. Liu, et al., Phys. Rev. Lett. 103, 026803 (2009)].

description: It is shown that the pi^0 transition form factor F(Q_1^2,Q_2^2) differs substantially from its one-real-photon limit F(Q_1^2,0) even for rather small values of Q_2^2 (approx 0.1 GeV^2), which cannot be excluded in experiments with one "untagged" electron. It indicates that the comparison of data with theoretical calculations, which usually assume Q_2^2=0, may be untrustworthy. Our phenomenological model of the pi^0 transition form factor is based on the vector-meson-dominance hypothesis and all its parameters are fixed by using the experimental data on the decays of vector mesons. The model soundness is checked in the two-real-photon limit, where it provides a good parameter-free description of the pi^0 -> 2 gamma decay rate, and in the pi^0 Dalitz decay. The dependence of F(Q_1^2,Q_2^2) on Q_1^2 at several fixed values of Q_2^2 is presented and the comparison with existing data performed.

description: Genus Kermadecia (Proteaceae) showed interesting biological activities related to their macrocyclic derivatives (kermadecin). Nevertheless, chemistry of Kermadecia sinuata was not studied until now. Phytochemical investigation of the bark of K. sinuata led to the isolation of two previously undescribed compounds: 4-(hydroxymethyl)-3,5-diphenyldihydrofuran-2(3H)-one, kermafuranone (1) and (+)-(5S,8R,9R,10S,5’S,8’S,9’R,10’S)-onocerane-8,8’-diol (2), along with four known compounds: methyl haematommate (3), atranorine (4), β-sitosterol (5) and docosyl ferulate (6). The structures of these compounds were elucidated by HRESIMS and NMR spectroscopic data analysis, and the absolute configuration of compound 2 was determined by single-crystal X-ray diffraction analysis. This compound is the first non-symmetrical onocerane-8,8’-diol. Hypothesised biosynthesis pathway was suggested for kermafuranone (1).

description: As governments increase their use of social media for public communication, many hold the expectation that these tools can help increase civic engagement and improve the quality of democracy. To understand if this is a mere expectation or accurately reflects the way social media is being used by governments, an empirical investigation was conducted, with two main goals: to understand how US local governments are actually using social media, that is, for what communication purposes they are using it (for this, three main purposes were proposed theoretically: Governance, Technocratic and Rhetoric); and to understand the internal organizational factors that explain the use of social media for these different purposes. Two different datasets were used for this investigation, one consisting of a qualitative analysis and coding of Facebook posts by local governments, and the other consisting of a broad survey answered by local government managers of five different departments (Mayor’s Office, Police, Finance, Community Development and Parks and Recreation). Results indicate that most departments are using social media for perfunctory purposes (Technocratic, for broadcast of information), but are not using it for more participatory, engagement purposes. As for the organizational factors, results indicate that some factors – such as legal obligation, positive attitudes towards social media and organizational guides for social media usage – positively affect most purposes of use, while other organizational factors – such as employee discretion – affect only certain purposes. The dissertation concludes with a discussion of the contributions for the theory and practice of public administration, in particular regarding the use of social media and technology in government.

description: We provide unambiguous theoretical evidence for the formation of correlation-induced isolated merons in rotationally-symmetric quantum dots. Our calculations rely on neither the lowest-Landau-level approximation, nor on the maximum-density-droplet approximation, nor on the existence of a spin-polarized state. For experimentally accessible system parameters, unbound merons condense in the ground state at magnetic fields as low as $B^* = 0.2$ T and for as few as N = 3 confined fermions. The four-fold degenerate ground-state at $B^*$ corresponds to four orthogonal merons $\ket{QC}$ characterized by their topological chirality $C$ and charge $Q$. This degeneracy is lifted by the Rashba and Dresselhaus spin-orbit interaction, which we include perturbatively, yielding spectroscopic accessibility to individual merons. We further derive a closed-form expression for the topological chirality in the form of a chiral spin current and use it to both characterize our states and predict the existence of other topological textures in other regions of phase space, for example, at N=5. Finally, we compare the spin textures of our numerically exact meron states to ansatz wave-functions of merons in quantum Hall droplets and find that the ansatz qualitatively describes the meron states.

Examining the Experience of African American Surrogate Decision Makers of Patients with Dementia

description: Introduction: Dementia cases are expected to grow for African Americans and surrogate decision makers (SDMs) will have a significant role at end-of-life (EOL). Evidence suggest African American caregivers serve as SDMs but lack sufficient knowledge of disease prognosis and interventions to plan care and make informed treatment choices at end-of life. This qualitative exploratory case study was conducted utilizing Cognitive Task Analysis (CTA) and an integrated conceptual framework to understand the end-of-life decision experience of African American SDMs for patients with advanced dementia. Methods: Using a qualitative exploratory case study with a holistic multiple case design, 8 African American SDMs were recruited and enrolled. Three 60-minute semi-structured interviews were conducted over 3 weeks. Surrogates received a Timeline Followback assessment prior to the first interview to highlight anchoring events. Interviews were audio-recorded then transcribed for coding and thematic analysis. Results: Themes germane to understanding the EOL decision experience of African American SDMs were reported. Surrogate decision making as a developmental process including role acceptance, role enactment, and emotional outcomes of deciding was described. Discussion: Findings suggest that African Americans extend the caregiver role to SDM for patients with dementia at EOL. Surrogate decision making is a developmental process. Culturally appropriate decision support to improve the quality of EOL treatment decisions and emotional adjustment of surrogates of patients with advanced dementia should be rendered early and throughout the illness trajectory.

description: Radio systems today exhibit a degree of flexibility that was unheard of only a few years ago. Software-defined radio architectures have emerged that are able to service large swathes of spectrum, covering up to several GHz in the UHF bands. This dissertation investigates interference mitigation techniques in frequency hopping ad hoc networks that are capable of exploiting the frequency agility of software-defined radio platforms.

description: The paper presents the results of psycholinguistic analysis of the stimulus words army, language, faith (in Ukrainian) as concept-forming nominations in the structure of the slogan- motto “Army. Language. Faith.”, which was used during the 2019 presidential election campaign in Ukraine, i.e., in the context of a particular discursive practice. In the study, the method of free associative experiment based on the speech influence theory was used that allowed to interpret the semantics of the analyzed concepts as well as to establish their closest connections and logical relationships with other concepts. Verbal reactions to a political slogan as a whole and to its individual structural units as concept-forming nominations are interpreted as verbal representations of cognitive features of concepts. The first two stages of the implementation of slogan-motto “Army. Language. Faith.” into mass consciousness, i.e. attracting attention to the text and optimization its perception, were successfully realized. The third stage, i.e. acceptance of the content, was complicated by certain extralinguistic and linguistic factors, such as the use of words “language”, “faith” which possess rather abstract, non-specific semantics. The results of the free associative experiment make it possible to identify markers of the deep (including subconscious) mechanisms of verbal and non-verbal behavior of individuals, which can be used to form new and transform old political concepts.
