Patient Crying in Psychotherapy: Who Cries and Why?
Authors: Capps Kristen L. , Fiori Katherine , Mullin Anthony S. J. , Hilsenroth Mark J. 
Published: December 2013

AimThe aim of the present study is to further the understanding of who cries in therapy and the relation of technique with crying behaviour in therapy.MethodPsychological assessment feedback sessions, prior to the initiation of formal therapy for 52 patients beginning psychotherapy at a university‐based clinic were coded for discrete crying segments. Data about patient characteristics and the process of the session were collected at the time of the session. Therapist's interventions were recorded verbatim and independently rated.ResultsThe number of times a patient cried during their session correlated negatively with global assessment of functioning scores and positively with measures of borderline personality disorder pathology as well as a measure of severity of childhood sexual abuse. Patients' crying behaviour demonstrated significant negative correlations with the overall experience of the session (bad/good), smoothness and positivity. Group differences between criers and non‐criers reflected these trends as well. No significant correlations or group differences were found with regard to patient‐rated or therapist‐rated alliance as it relates to crying behaviour. Analysis indicates that therapist intervention prior to patient crying most often encouraged the exploration and expression of difficult affect, new perspectives on key issues or the patient's fantasies and wishes.DiscussionOur study addresses a significant gap in the clinical literature on crying. Crying behaviour seems to be related to certain clinical variables and has a negative impact on patient experience of the session in which they cry, although the alliance remained unaffected.LimitationsSmall sample, outpatients with mild/moderate psychopathology and graduate trainees provided therapy.

Patients with greater problems in emotional dysregulation, borderline personality disorder symptoms and greater severity of childhood sexual abuse are more likely to display greater affective intensity during the beginning of treatment.
Results suggest that the alliance may remain strong despite patients experiencing a session in which they cried as difficult.
Therapeutic interventions that focus on affect, new understanding of old patterns and patient fantasies with outpatient clinical populations appeared to be associated with crying in session.

AbstractA new type of ionic liquid that contains a nitroxide radical (NO.) and iodide as two redox couples, JC‐IL, has been successfully synthesized for high‐performance dye‐sensitized solar cells (DSSCs). Both of the redox couples exhibit distinct redox potentials and attractive electrochemical characteristics. The UV/Vis absorption spectra of JC‐IL shows a low‐intensity peak compared to the strong absorption of I2 in the wavelength region of 350–500 nm. The high open‐circuit voltage of DSSCs with JC‐IL is over 850 mV, which is approximately 150 mV higher than that of the DSSCs with a standard iodide electrolyte. The dramatic increase in the standard heterogeneous electron‐transfer rate constant leads to an increase in the short‐circuit current for JC‐IL compared to that of 2,2,6,6‐tetramethylpiperidin‐N‐oxyl (TEMPO). DSSCs with the JC‐IL electrolyte show promising cell efficiencies if coupled with dyes CR147 (8.12 %) or D149 (6.76 %). The efficiencies of the DSSCs based on the JC‐IL electrolyte are higher than those of DSSCs based on either TEMPO electrolyte or standard iodide electrolyte alone.
Quantifying habitat impacts of natural gas infrastructure to facilitate biodiversity offsetting

Published: December 2013

AbstractHabitat degradation through anthropogenic development is a key driver of biodiversity loss. One way to compensate losses is “biodiversity offsetting” (wherein biodiversity impacted is “replaced” through restoration elsewhere). A challenge in implementing offsets, which has received scant attention in the literature, is the accurate determination of residual biodiversity losses. We explore this challenge for offsetting gas extraction in theUstyurtPlateau,Uzbekistan. Our goal was to determine the landscape extent of habitat impacts, particularly how the footprint of “linear” infrastructure (i.e. roads, pipelines), often disregarded in compensation calculations, compares with “hub” infrastructure (i.e. extraction facilities). We measured vegetation cover and plant species richness using the line‐intercept method, along transects running from infrastructure/control sites outward for 500 m, accounting for wind direction to identify dust deposition impacts. Findings from 24 transects were extrapolated to the broader plateau by mapping total landscape infrastructure network usingGPSdata and satellite imagery. Vegetation cover and species richness were significantly lower at development sites than controls. These differences disappeared within 25 m of the edge of the area physically occupied by infrastructure. The current habitat footprint of gas infrastructure is 220 ± 19 km2across theUstyurt (total ~ 100,000 km2), 37 ± 6% of which is linear infrastructure. Vegetation impacts diminish rapidly with increasing distance from infrastructure, and localized dust deposition does not conspicuously extend the disturbance footprint. Habitat losses from gas extraction infrastructure cover 0.2% of the study area, but this reflects directly eliminated vegetation only. Impacts upon fauna pose a more difficult determination, as these require accounting for behavioral and demographic responses to disturbance by elusive mammals, including threatened species. This study demonstrates that impacts of linear infrastructure in regions such as theUstyurt should be accounted for not just with respect to development sites but also associated transportation and delivery routes.
A meta‐analysis of declines in local species richness from human disturbances
Authors: Murphy Grace E. P. , Romanuk Tamara N. 
Published: December 2013

AbstractThere is high uncertainty surrounding the magnitude of current and future biodiversity loss that is occurring due to human disturbances. Here, we present a global meta‐analysis of experimental and observational studies that report 327 measures of change in species richness between disturbed and undisturbed habitats across both terrestrial and aquatic biomes. On average, human‐mediated disturbances lead to an 18.3% decline in species richness. Declines in species richness were highest for endotherms (33.2%), followed by producers (25.1%), and ectotherms (10.5%). Land‐use change and species invasions had the largest impact on species richness resulting in a 24.8% and 23.7% decline, respectively, followed by habitat loss (14%), nutrient addition (8.2%), and increases in temperature (3.6%). Across all disturbances, declines in species richness were greater for terrestrial biomes (22.4%) than aquatic biomes (5.9%). In the tropics, habitat loss and land‐use change had the largest impact on species richness, whereas in the boreal forest and Northern temperate forests, species invasions had the largest impact on species richness. Along with revealing trends in changes in species richness for different disturbances, biomes, and taxa, our results also identify critical knowledge gaps for predicting the effects of human disturbance on Earth's biomes.

Published: December 2013

ABSTRACTIn the literature, contrasting effects of plant species richness on the soil water balance are reported. Our objective was to assess the effects of plant species and functional richness and functional identity on soil water contents and water fluxes in the experimental grassland of the Jena Experiment. The Jena Experiment comprises 86 plots on which plant species richness (0, 1, 2, 4, 8, 16, and 60) and functional group composition (zero to four functional groups: legumes, grasses, tall herbs, and small herbs) were manipulated in a factorial design. We recorded meteorological data and soil water contents of the 0·0–0·3 and 0·3–0·7 m soil layers and calculated actual evapotranspiration (ETa), downward flux (DF), and capillary rise with a soil water balance model for the period 2003–2007. Missing water contents were estimated with a Bayesian hierarchical model. Species richness decreased water contents in subsoil during wet soil conditions. Presence of tall herbs increased soil water contents in topsoil during dry conditions and decreased soil water contents in subsoil during wet conditions. Presence of grasses generally decreased water contents in topsoil, particularly during dry phases; increased ETa and decreased DF from topsoil; and decreased ETa from subsoil. Presence of legumes, in contrast, decreased ETa and increased DF from topsoil and increased ETa from subsoil. Species richness probably resulted in complementary water use. Specific functional groups likely affected the water balance via specific root traits (e.g. shallow dense roots of grasses and deep taproots of tall herbs) or specific shading intensity caused by functional group effects on vegetation cover.

Intercalation of Diverse Organic Guests into Layered Europium Hydroxides – Structural Tuning and Photoluminescence Behavior
Authors: Gu Qingyang , Chu Nankai , Pan Guohua , Sun Genban , Ma Shulan , Yang Xiaojing 
Published: December 2013

AbstractOrganic anions of two benzenepolycarboxylic acids [1,3,5‐benzenetricarboxylic acid (BTA) and 2,2′‐biphenyldicarboxylic acid (BDA)], two pyridinecarboxylic acids [quinolinic acid (QA) and 2,5‐pyridinedicarboxylic acid (PDA)], and two amino acids [phenylalanine (Phe) and tyrosine (Tyr)] were intercalated into the galleries of NO3–‐type layered europium hydroxide (NO3–LEuH). All the prepared products displayed XRD patterns with series of diffractions due to layered materials. The composite structures and the arrangement of the guests in the galleries were investigated in detail. The structure of the organic guests (such as the number and position of carboxyl groups) affects the arrangement in the interlayer. SEM observations showed that the NO3–LEuH precursor and its intercalates crystallize in a columnar or layered stacking structure composed of hexagonal thin platelets. The luminescence study indicated that all samples display the typical red emission of Eu3+. Efficient energy transfer between intercalated BTA/BDA anions and Eu3+ centers takes place, markedly enhancing the Eu3+ luminescence, whereas QA–LEuH and PDA–LEuH with pyridinedicarboxylic acid anions show no obvious change in luminescence intensity. When amino acid anions such as Phe and Tyr were introduced into the interlayer, the Eu3+ emission was strongly quenched. The simple soft chemical method can open great opportunities for developing organic–inorganic multifunctional luminescent materials or biological probes for detecting certain amino acids.
Photosensitive Metal(II) Perchlorates with 1,2‐Bis[5‐(1‐methylhydrazinyl)tetrazol‐1‐yl]ethane as Ligand: Synthesis, Characterization and Laser Ignition

Published: December 2013

AbstractThe synthesis and characterization (including NMR spectroscopy, elemental analysis, X‐ray diffraction, infrared spectroscopy and sensitivity measurements) of 1,2‐bis[5‐(1‐methylhydrazinyl)tetrazol‐1‐yl]ethane (1) and its corresponding metal [Cu2+(2), Co2+(3), Ni2+(4)] complexes is presented. The crystal structure of the copper(II) complex was determined and infrared spectra of all three coordination compounds were recorded. Furthermore, the behaviour of the metal(II) complexes towards single‐pulsed laser irradiation was investigated and it was shown that all three perchlorate complexes detonated after initiation by monopulsed laser light. The initiation mechanism seems to be of thermal nature.

Published: December 2013

AbstractPiperazirum, a new biologically active alkaloid isolated from Arum palaestinum Bioss, is described, starting from commercially available α‐amino acids. Two synthetic strategies were developed for the synthesis of the enantiomeric pair of compounds corresponding to the proposed structure of piperazirum. The first strategy was used in the synthesis of stereoisomers, and the second one was used in generating the analogues. The compounds synthesized were screened against different cell lines to evaluate their cytotoxicity profiles.
