    Attachment Theory suggests interaction with caregivers in childhood impacts relationships and health throughout our lives (Bowlby, 1965, 1969, 1971), leaving many who have experienced insecure attachment with an inability to form healthy relationships or cope with stressors throughout their lifespan (Holmberg, Lomore, Takacs, & Price, 2011). Horses have interacted with humans for over 12,000 years (Hintz, 1995), holding multiple roles in human society, most relying on observation by humans of equine behavior, and formation of a human-equine bond (Hamilton, 2011). More securely attached humans tend to more readily decipher non-verbal cues, positively affecting their felt security and internal working model of Attachment (Bachi, 2013). Interacting with horses, who provide significant non-verbal cues, may provide an opportunity to enhance this process, providing useful feedback and insight. This study aimed to evaluate if a single ground-based encounter with a horse could bring about changes in women participants’ reports of Attachment and Emotion Regulation. It was hypothesized that participants would move towards more secure dimensions of Attachment and Emotion Regulations after the encounter with the horse and that behavioral interactions with the horse would differ for those with differing dimensions of Attachment or Emotion Regulation. This study incorporated a repeated measures mixed methods design, one twenty-eight year old Standardbred mare, “Wicky” Long Wick, interacted with 22 female university students with minimal prior equine experience aged 18-30. Participants completing a demographic and screening questionnaire along with the Experiences in Close Relationships –Revised (ECR)(Brennan, Clark, & Shaver, 1998) and Emotion Regulation Questionnaires (ERQ)(Gross & John, 2003) at baseline, then the ECR and ERQ again both immediately prior to and immediately following encounter with the horse. The encounter was videotaped and included meeting, grooming, leading, and goodbye. Statistical analyses were completed using SPSS including paired t-tests and correlations. Videotape was evaluated, coded, and included in both quantitative and qualitative data analyses. Participants were recruited and participated in the study over the period of one calendar year. A significant decrease in Attachment anxiety was shown after encountering the horse (t(21)=2.915, p=.008 (M .237364, SD= .381941)), and significantly less time was spent between the horse and participant at goodbye than at meeting (t (21)=2.751, p=.021 (M 42.045, SD= 71.67)), particularly for those with insecure dimensions of Attachment (t (15)= 2.814, p=.013 (M= 45.75, SD=65.03)). Participants with insecure dimensions of Attachment showed significant increases in cognitive reappraisal after encountering the horse (t(14)= -3.732, p=.002 (M -.411, SD= .4266)), and the greatest decreases in Attachment Anxiety (t(14)=3.364, p=.005 (M .307, SD= .354)). The findings suggest interaction between horses and people differs along Attachment dimensions and show some support for positive changes in humans for both Attachment and Emotion Regulation dimensions after interaction with a horse

    Multi-bubble nodal solutions for slightly subcritical elliptic problems in domains with symmetries

    We study the existence of sign-changing solutions with multiple bubbles to the slightly subcritical problem -\Delta u=|u|^{2^*-2-\e}u \hbox{in}\Omega, \quad u=0 \hbox{on}\partial \Omega, where Ω\Omega is a smooth bounded domain in RN\R^N, N3N\geq 3, 2=2NN22^*=\frac{2N}{N-2} and \e>0 is a small parameter. In particular we prove that if Ω\Omega is convex and satisfies a certain symmetry, then a nodal four-bubble solution exists with two positive and two negative bubbles

    “It sounds silly now, but it was important then”: Supporting the significance of a personal experience in psychotherapy

    The article examines a previously undocumented practice whereby psychotherapy clients support the significance of their experience against the background of how it can otherwise be heard. This practice is the phrase “it sounds X, but Y” (e.g., “which sounds silly now, but was like important then”). We call this an SXB-contrast. We used conversation analysis to examine 21 instances of this phenomenon, identified in 12 audio-recorded individual psychotherapy sessions involving 10 clients and 8 therapists. Clients use SXB-contrasts to mark part of their talk as delicate, specifically by voicing an unsympathetic hearing of that talk whilst supporting its experiential significance. Evidence for our claims comes from clients’ use of SXB-contrasts in association with practices of speech delivery (e.g., laughter) and self-repair operations which also establish a part of their talk as delicate. Therapist responses provide additional supporting evidence. The study contributes to understanding how clients can use meta-talk to convey the meaning of their experiences in therapy whilst also making available their own emerging awareness of the multiple meanings of those experiences

    Molecular Phylogenetics of Alternanthera (Gomphrenoideae, Amaranthaceae): Resolving a Complex Taxonomic History Caused by Different Interpretations of Morphological Characters in a Lineage with C4 and C3-C4 Intermediate Species

    Aternanthera (Amaranthaceae) is a diverse genus (80-200 species) largely restricted to the American Tropics. With Pedersenia and Tidestromia, it makes up the Alternantheroid clade in Gomphrenoideae. Parsimony and Bayesian analyses of nucleotide sequences of nuclear (ITS) and plastid (rpl16, trnL-F) and morphological characters identify that the capitate stigma of Alternanthera is a synapomorpy within the Alternantheroids. Within Alternanthera, two major clades were resolved, both of which were marked by otherwise homoplasious characters of the gynoecium: Clade A [99% jackknife (JK); 1.0 posterior probability (PP)] with nine species and Clade B (60% JK; 0.98 PP) with 22 species. Four subclades (B1B4), strongly supported statistically, were identified in Clade B. Previous subgeneric classifications of Alternanthera appear artificial in light of our new molecular phylogenetic analyses. Most major lineages are congruently resolved by nuclear and plastid data but some incongruence between the nrITS and plastid phylogenetic trees suggests hybridization may have played a role in the rampant speciation in Alternanthera. Whereas C4 photosynthesis appears to have evolved in a single clade, the position of A. littoralis var. maritima (C3) in this clade may be explained by hybrid speciation rather than a reversal from C4 to C3. All C3-C4 intermediates belong to a different clade that also contains C3 species, but species limits, including the widely studied A. tenella, are unclear. The clade including A. tenella and A. halimifolia contains most of the species endemic to the Galápagos whereas A. nesiotes, also endemic to the islands, is nested among widespread American taxa. This suggests that the Galápagos radiation of Alternanthera may have arisen from at least two independent colonization events followed by a subsequent radiation in the former lineage. © 2012 The Linnean Society of London

    Are the Goals of Sustainability Interconnected? A Sociological Analysis of the Three E’s of Sustainable Development Using Cross-Lagged Models with Reciprocal Effects

    Conceptual discussions of sustainability emphasize the interdependent relationship between relevant social and environmental factors. Yet, traditional quantitative analyses of the topic have tended to estimate the exogenous or direct/indirect effects a predictor variable has on a particular measure of sustainability. We examine the endogenous, interdependent relationship between the three E’s of sustainability (economy, equity, and ecology), incorporating country-level data for 1990 through 2015 into cross-lagged structural equation models with reciprocal and fixed effects. Results from these longitudinal models suggest that over time, at the country level, increasing economic inequality reduces renewable energy consumption, with no evidence of reciprocal feedback. Keeping in mind the limitations of the analysis, we tentatively argue that the modern form of development has constrained the potential for the sustainability goals to feed back into each other

    Absolute fraction of emitted Ps determined by GEANT4 supported analysis of gamma spectra

    Full text link
    The fraction of positronium (Ps) emitted from a surface of a germanium single crystal at high temperature is usually assumed to approach unity at zero positron implantation energy. In the experiment, however, the determination of the absolute Ps fraction is not straight forward since recording a reference spectrum with 100%100\,\% Ps formation remains demanding. We use GEANT4-simulated detector responses to 2γ2\gamma and 3γ3\gamma radiation sources mimicking positron and Ps annihilation inside the (coincidence) Doppler-broadening spectrometer at NEPOMUC, FRM II, in order to derive a reliable value for the Ps fraction reemitted from a Ge(100) target heated close to its melting point. Analysis of the measured spectra by fitting the simulated spectra shows an absolute value of (72±4)%(72\,\pm{4})\,\% maximum Ps formation, contradicting the 100%100\,\% assumption

    The optical spectrum of a large isolated polycyclic aromatic hydrocarbon: hexa-peri-hexabenzocoronene, C42H18

    Full text link
    The first optical spectrum of an isolated polycyclic aromatic hydrocarbon large enough to survive the photophysical conditions of the interstellar medium is reported. Vibronic bands of the first electronic transition of the all benzenoid polycyclic aromatic hydrocarbon hexa-peri-hexabenzocoronene were observed in the 4080-4530 Angstrom range by resonant 2-color 2-photon ionization spectroscopy. The strongest feature at 4264 Angstrom is estimated to have an oscillator strength of f=1.4x10^-3, placing an upper limit on the interstellar abundance of this polycyclic aromatic hydrocarbon at 4x10^12 cm^-2, accounting for a maximum of ~0.02% of interstellar carbon. This study opens up the possibility to rigorously test neutral polycyclic aromatic hydrocarbons as carriers of the diffuse interstellar bands in the near future.Comment: 9 pages, 1 figure.
