Experiences of therapists who integrate walk and talk into their professional practice
Authors: Revell Stephanie , McLeod John 
Published: December 2016

AbstractBackgroundThere has been increasing interest in recent years in the possibilities arising from conducting psychotherapy in outdoor settings, for example through the use of ‘walk and talk’ sessions.AimThis study aimed to explore the experiences of practitioners who use this approach, in terms of helpful and hindering factors.MethodEighteen walk and talk practitioners completed an online mixed‐methods questionnaire.FindingsParticipants perceived that walking and talking can help shift ‘stuckness’ in clients and facilitate psychological processing. In addition, practitioners indicated that walking side by side can promote a collaborative way of working. Hindering factors included working with uncertainty, issues around maintaining boundaries and the requirement to develop new skills.LimitationsThe sample size and use of an online survey limited the amount and richness of information obtained.ImplicationsThe results suggest that walk and talk is an emergent psychotherapeutic approach, characterised by a substantial degree of consensus across practitioners regarding the rationale for this type of intervention, and the facilitative processes that are supported by it. It would be valuable to develop research‐informed guidelines and training opportunities to support safe practice in this area of work.
Progressive counting with therapy clients with post‐traumatic stress disorder: Three cases
Authors: Jarecki Kriss , Greenwald Ricky 
Published: December 2016

AbstractBackgroundProgressive counting (PC) is a recently developed trauma treatment that has shown promise in several studies with non‐therapy‐client samples.AimThe aim of this archival study was to determine whether PC's effectiveness found in other research might carry over to post‐traumatic stress disorder (PTSD) cases in clinical practice.MethodThe present case series included three consecutive cases in the first author's clinical practice, in which the client was diagnosed with PTSD, and in which PC was used.FindingsEach participant showed remission of PTSD and substantial reduction or elimination of presenting problems, with results persisting at one‐year follow‐up. Three other cases, which were excluded because post‐treatment or follow‐up data were not available, showed a similar pattern of symptom reduction.ImplicationsThese findings suggest that PC can be beneficial with therapy clients with PTSD.
The impact of suicide prevention on experienced Irish clinicians
Authors: Moore Heather , Donohue Gráinne 
Published: December 2016

AbstractBackgroundEmerging research coming from the person‐centred and psychodynamic traditions in the past 15 years has examined the traumatic dimension of suicidal behaviour on clinicians. However, there is limited empirical literature on the impact of suicidality on Irish psychotherapists. In Ireland, it is estimated that 500 citizens die by suicide each year, while approximately 11,000 accident and emergency admissions are the consequence of suicide attempts.AimThis elicits the question, how does suicide prevention impact Irish mental health professionals who work solely with these vulnerable populations?MethodIn this article, the process of interpretative phenomenological analysis (IPA) was applied to the narratives of seven experienced therapists.FindingsThe Irish Poet W.B. Yeats coined the famous refrain ‘All changed, changed utterly, a terrible beauty is born’ in his poem ‘Easter 1916’ (as cited in Martin, ). This quote aptly encapsulates the reality of seven experienced Irish psychotherapists who work exclusively in the field of suicide prevention. Three salient superordinate themes emerged: (1) Overworking; (2) All changed, changed utterly/identity disruption; (3) A terrible beauty is born/A spiritual practice.DiscussionClinicians were ‘changed, changed utterly’ with identity disruption evident in their self, bodies, intimate relationships and professional identity. ‘A terrible beauty was born’ was demonstrated in the overarching theme of the restorative nature of client engagement in the life of the therapist. This was particularly evident in humanistic practitioners, who were acutely aware of their own sublimation of melancholia.ConclusionMost striking across all seven transcripts was the mix of the corrosive nature of suicide prevention on the self of the therapist, combined with unparalleled opportunities for personal growth and spiritual reformulation.
Analyzing the returns of the first transaction satisfaction on intention to purchase and willingness to pay: Evidence for new food products
Authors: Tudoran Ana Alina , Olsen Svein Ottar 
Published: December 2016

AbstractThe present study sheds light on the kind of relationships that link first transaction consumer satisfaction (CS), purchase intention, and willingness to pay for new food products. The article presents a comparative evaluation of linear and nonlinear quadratic and cubic specifications used to assess the relationships involved. The study uses empirical evidence from three product‐testing field experiments with consumers in different natural settings such as at‐home and out‐of‐home. Statistical tests with structural equation modeling reveal that, for new food products, the CS–purchase intention relationship is characterized by a nonlinear functional form with increasing marginal returns, while the CS–willingness to pay relationship is defined by a linear functional form with constant marginal returns. The study contributes to the existing body of knowledge that so far has mainly described the relationship between cumulative CS and profit chain outcomes in the context of established products (brands). We discuss the implications for managers responsible for launching new food products and give hints on allocating resources to the most probable customers. Copyright © 2016 John Wiley & Sons, Ltd.
Carbones as Ligands in Novel Main‐Group Compounds E[C(NHC)2]2 (E=Be, B+, C2+, N3+, Mg, Al+, Si2+, P3+): A Theoretical Study
Authors: Hermann Markus , Frenking Gernot 
Published: December 2016

AbstractQuantum chemical calculations of the main‐group compounds E[C(NHCMe)2]2 (E=Be, B+, C2+, N3+, Mg, Al+, Si2+, P3+) have been carried out using density functional theory at the BP86/def2‐TZVPP and BP86‐D3(BJ)/def2‐TZVPP levels of theory. The geometry optimization at BP86/def2‐TZVPP gives equilibrium structures with two‐coordinated species E and bending angles C‐E‐C between 152.5° (E=Be) and 110.5° (E=Al). Inclusion of dispersion forces at BP86‐D3(BJ)/def2‐TZVPP yields a three‐coordinated beryllium compound Be[C(NHCMe)2]2 as the only energy minimum form. Three‐coordinated isomers are found besides the two‐coordinated energy minima for the boron and carbon cations B[C(NHCMe)2]2+ and C[C(NHCMe)2]22+. The three‐coordinated form of the boron compound is energetically lower lying than the two‐coordinated form, while the opposite trend is calculated for the carbon species. The theoretically predicted bond dissociation energies suggest that all compounds are viable species for experimental studies. The X‐ray structure of the benzoannelated homologue of P[C(NHCMe)2]23+ that was recently reported by Dordevic et al. agrees quite well with the calculated geometry of the molecule. A detailed bonding analysis using charge and energy decomposition methods shows that the two‐coordinated neutral compounds Be[C(NHCMe)2]2 and Mg[C(NHCMe)2]2 possess strongly positively charged atoms Be and Mg. The carbodicarbene groups C(NHCMe)2 serve as acceptor ligands in the compounds and may be sketched with dative bonds (NHCMe)2C←E→C(NHCMe)2 (E=Be, Mg). Dative bonds in which the carbones C(NHCMe)2 are donor ligands are suggested for the cations (NHCMe)2C→E←C(NHCMe)2 (E=B+, Al+). The dications and trications possess electron‐sharing bonds in which the bonding situation is best described with the formula [(NHCMe)2C]+‐E‐[C(NHCMe)2]+ (E=C, Si, N+, P+).

AbstractA design approach that incorporates structural requirements for the formation of a 1D assembly, fibril stability, and fibril–fibril interactions for gelation was attempted by using amino acid‐based sulfamides with the general structure Aa‐NH‐SO2‐NH‐Aa (Aa=amino acid). A preference for 1D assembly alone was not a sufficient condition for gelation, which became evident from studies involving sulfamide esters 1–5. Reducing the crystallization tendency without hindering unidirectional growth was executed through diacids of the sulfamide precursors with various amines that form an envelope around the sulfamide core through salt bridges. This strategy was fruitful, and gels of a wide variety of solvents could be formed by varying the acid and amine components. The use of dodecylamine or benzylamine, which could stabilize the molecular layers through alkyl‐chain segregation or π–π interactions improved the gelation tendency, whereas the nature of the amino acid side chain, especially the rotational freedom and hydrophobicity, had a direct role in dictating the solvent preference. Crystallographic studies of these two‐component systems gave molecular‐level insight into the assembly and showed the importance of anisotropy in the distribution of secondary interactions in gelation.
Access to Enantiopure Triarylmethanes and 1,1‐Diarylalkanes by NHC‐Catalyzed Acylative Desymmetrization

Published: December 2016

AbstractWe present herein an unprecedented, efficient and enantioselective synthesis of triarylmethanes and 1,1‐diarylalkanes through N‐heterocyclic carbene‐catalyzed acylative desymmetrization of bisphenols. This method utilizes readily available substrates, reagents and a simple procedure to deliver the valuable products in excellent enantiopurity. DFT calculations reveal that the selectivity is governed by the C−C bond cleavage step of the tetrahedral intermediate leading to the ester product. A transition state model featuring a combination of intramolecular hydrogen bond and steric effect is developed to explain the enantioselectivity.

BackgroundPatients with coronary microvascular dysfunction (CMD) often have diastolic dysfunction, representing an important therapeutic target. Ranolazine—a late sodium current inhibitor—improves diastolic function in animal models and subjects with obstructive coronary artery disease (CAD).HypothesisWe hypothesized that ranolazine would beneficially alter diastolic function in CMD.MethodsTo test this hypothesis, we performed retrospective tissue tracking analysis to evaluate systolic/diastolic strain, using cardiac magnetic resonance imaging cine images acquired in a recently completed, randomized, double‐blind, placebo‐controlled, crossover trial of short‐term ranolazine in subjects with CMD and from 43 healthy reference controls.ResultsDiastolic strain rate was impaired in CMD vs controls (circumferential diastolic strain rate: 99.9% ± 2.5%/s vs 120.1% ± 4.0%/s, P = 0.0003; radial diastolic strain rate: −199.5% ± 5.5%/s vs −243.1% ± 9.6%/s, P = 0.0008, case vs control). Moreover, peak systolic circumferential strain (CS) and radial strain (RS) were also impaired in cases vs controls (CS: −18.8% ± 0.3% vs −20.7% ± 0.3%; RS: 35.8% ± 0.7% vs 41.4% ± 0.9%; respectively; both P < 0.0001), despite similar and preserved ejection fraction. In contrast to our hypothesis, however, we observed no significant changes in left ventricular diastolic function in CMD cases after 2 weeks of ranolazine vs placebo.ConclusionsThe case‐control comparison both confirms and extends our prior observations of diastolic dysfunction in CMD. That CMD cases were also found to have subclinical systolic dysfunction is a novel finding, highlighting the utility of this retrospective approach. In contrast to previous studies in obstructive CAD, ranolazine did not improve diastolic function in CMD.
Gluing Eguchi‐Hanson Metrics and a Question of Page
Authors: Brendle Simon , Kapouleas Nikolaos 
Published: December 2016

AbstractIn 1978, Gibbons‐Pope and Page proposed a physical picture for the Ricci flat Kähler metrics on the K3 surface based on a gluing construction. In this construction, one starts from a flat torus with 16 orbifold points and resolves the orbifold singularities by gluing in 16 small Eguchi‐Hanson manifolds that all have the same orientation. This construction was carried out rigorously by Topiwala, LeBrun‐Singer, and Donaldson. In 1981, Page asked whether the above construction can be modified by reversing the orientations of some of the Eguchi‐Hanson manifolds. This is a subtle question: if successful, this construction would produce Einstein metrics that are neither Kähler nor self‐dual. In this paper, we focus on a configuration of maximal symmetry involving eight small Eguchi‐Hanson manifolds of each orientation that are arranged according to a chessboard pattern. By analyzing the interactions between Eguchi‐Hanson manifolds with opposite orientation, we identify a nonvanishing obstruction to the gluing problem, thereby destroying any hope of producing a metric of zero Ricci curvature in this way. Using this obstruction, we are able to understand the dynamics of such metrics under Ricci flow as long as the Eguchi‐Hanson manifolds remain small. In particular, for the configuration described above, we obtain an ancient solution to the Ricci flow with the property that the maximum of the Riemann curvature tensor blows up at a rate of , while the maximum of the Ricci curvature converges to 0.© 2016 Wiley Periodicals, Inc.
Psychopathological Differences Between Suicide Ideators and Suicide Attempters in Patients with Mental Disorders
Authors: Pérez Sandra , Marco Jose H. , García‐Alandete Joaquin 
Published: December 2016

BackgroundAlthough suicide is one of the leading causes of death worldwide, there is a need for studies to identify variables that can differentiate patients with suicide ideation at risk of transitioning to an attempt.MethodIn this study, we assessed suicide ideation and attempts, non‐suicidal self‐injury (NSSI), hopelessness, borderline symptoms and meaning in life in a sample of 348 patients with different diagnoses of mental disorders. We divided the sample into four subgroups: patients without suicide ideation or suicide attempts; patients with current suicide ideation; patients with lifetime suicide attempts and patients with a suicide attempt in the previous year.ResultsThe group with suicide attempts in the previous year showed higher levels of hopelessness, borderline symptoms and NSSI, and lower levels of meaning in life than the other groups.LimitationsGroups were composed of unequal numbers of patients, and in some of them, the sample size was small. The sample was composed mainly of women with eating disorders. The study design was retrospective, and so the results must be considered in terms of correlates.ConclusionsOur results suggest that hopelessness, borderline symptoms—including NSSI—and meaning in life play a key role in suicide attempts. Thus, psychotherapeutic interventions should focus on managing NSSI, searching for meaning and managing emptiness, loss of control and feelings such as self‐contempt in patients with suicide ideation.

Recent suicide attempters show higher levels of hopelessness, borderline symptoms and NSSI than lifetime attempters and suicide ideators.
Clinicians should focus attention on assessing hopelessness, borderline symptoms and NSSI in those with suicide ideation.
Lower levels of meaning in life are related to recent suicide attempts.
Levels of hopelessness differentiate between recent and lifetime suicide attempters.
A Model Study to Unravel the Complexity of Bio‐Oil from Organic Wastes

Published: December 2016

AbstractBinary and ternary mixtures of cellulose, bovine serum albumin (BSA) and tripalmitin, as biomass reference compounds for carbohydrates, proteins and triglycerides, respectively, were treated under hydrothermal liquefaction (HTL) conditions to describe the main reaction pathways involved in the process of bio‐oil production from municipal organic wastes. Several analytical techniques (elemental analysis, GC–MS, atmospheric‐pressure photo‐ionisation high‐resolution Fourier transform ion cyclotron resonance mass spectrometry, and 13C cross‐polarisation magic‐angle spinning NMR spectroscopy) were used for the molecular‐level characterisation of the resulting aqueous phase, solid residue and bio‐oil, in particular. The main reaction pathways led to free fatty acids, fatty acid amides, 2,5‐diketopiperazines and Maillard‐type compounds as the main components of the bio‐oil. The relationship of such compounds to the original components of the biomass was thus determined, which highlights the fate of the heteroatom‐containing molecules in particular. Finally, the molecular composition of the bio‐oils from our reference compounds was matched with that of the bio‐oil from municipal organic waste biomass by comparing their high‐resolution Fourier transform ion cyclotron resonance mass spectra, and we obtained a surprisingly high similarity. Hence, the ternary mixture acts as a reliable biomass model and is a powerful tool to clarify the degradation mechanisms that occur in the biomass under HTL treatment, with the ultimate goal to improve the HTL process itself by modulating the input of the organic starting matter and then the upgrading steps to bio‐fuels.
Strongly secure ID‐based authenticated key agreement protocol for mobile multi‐server environments
Authors: Tseng Yuh‐Min , Huang Sen‐Shan , You Meng‐Lin 
Published: December 2016

SummaryTo provide mutual authentication and communication confidentiality between mobile clients and servers, numerous identity‐based authenticated key agreement (ID‐AKA) protocols were proposed to authenticate each other while constructing a common session key. In most of the existing ID‐AKA protocols, ephemeral secrets (random values) are involved in the computations of the common session key between mobile client and server. Thus, these ID‐AKA protocols might become vulnerable because of the ephemeral‐secret‐leakage (ESL) attacks in the sense that if the involved ephemeral secrets are compromised, an adversary could compute session keys and reveal the private keys of participants in an AKA protocol. Very recently, 2 ID‐AKA protocols were proposed to withstand the ESL attacks. One of them is suitable for single server environment and requires no pairing operations on the mobile client side. The other one fits multi‐server environments, but requires 2 expensive pairing operations. In this article, we present a strongly secure ID‐AKA protocol resisting ESL attacks under mobile multi‐server environments. By performance analysis and comparisons, we demonstrate that our protocol requires the lowest communication overhead, does not require any pairing operations, and is well suitable for mobile devices with limited computing capability. For security analysis, our protocol is provably secure under the computational Diffie‐Hellman assumption in the random oracle model.
Stabilization of a salamander moving hybrid zone

Published: December 2016

AbstractWhen related species meet upon postglacial range expansion, hybrid zones are frequently formed. Theory predicts that such zones may move over the landscape until equilibrium conditions are reached. One hybrid zone observed to be moving in historical times (1950–1979) is that of the pond‐breeding salamandersTriturus cristatusandTriturus marmoratusin western France. We identified the ecological correlates of the species hybrid zone as elevation, forestation, and hedgerows favoring the more terrestrialT. marmoratusand pond density favoring the more aquaticT. cristatus. The past movement of the zone of ca. 30 km over three decades has probably been driven by the drastic postwar reduction of the “bocage” hedgerow landscape, favoringT. cristatusoverT. marmoratus. No further hybrid zone movement was observed from 1979 to the present. To explain the changing dynamics of the hybrid zone, we propose that it stalled, either because an equilibrium was found at an altitude of ca. 140 m a.s.l. or due to pond loss and decreased population densities. While we cannot rule out the former explanation, we found support for the latter. Under agricultural intensification, ponds in the study area are lost at an unprecedented rate of 5.5% per year, so that remainingTrituruspopulations are increasingly isolated, hampering dispersal and further hybrid zone movement.

Published: December 2016

ObjectiveRecent research indicates considerable heterogeneity in the provision of memory assessment services (MAS). However, little is known on the extent of variation in the costs of the services MAS provide. We investigated the costs of supporting patients with suspected dementia, including assessment and support over the following 6 months.MethodsClinic costs were estimated on the basis of an organisational survey reporting staff roll, grade and activities. Costs of primary health and social care were estimated from questionnaire data reported by carers of patients at baseline, 3 and 6 months after referral.ResultsMean monthly staff costs at MAS were £73 000. Imaging at assessment costs an additional £3500 per month. Monthly clinic cost per new patient assessed varied from £320 to £5400 across clinics. Additional primary health and social care costs of £130–220 a month between baseline and 6 months were reported by carers. Costs of pharmacological and non‐pharmacological treatments reported by carers were small. Informal care costs dwarfed health and social care costs when valued at a modest unit cost. The overall mean cost of supporting a patient for 6 months varied from £1600 to £2500 dependent on assumptions regarding the proportion of MAS intervention and review costs accrued at 6 months.ConclusionsThere is considerable variation in the intensity and associated costs of services provided by MAS. Further research should ascertain to what extent such variation is associated with differences in patient outcomes. Copyright © 2016 John Wiley & Sons, Ltd.
