Bankruptcy Prediction of Industrial Industry in the UK
Authors: Nok Wong Ming
Published: December 2017

We make comparison between 6 models including (1) Altman’s (1968) z-score; (2) Model 1: z-score model with adjusted coefficients; (3) Model 2: z-score model with modified variables; (4) Model 3: dynamic logic model; (5) Merton distance to default (DD) model (Bharath & Shumway, 2008) and (6) back-propagation network model (Lippman, 1987). We assess the relative information content of these models regarding their bankruptcy prediction capability. Our tests show that dynamic logic model and DD model both provide significantly more information than the others while DD model has the highest prediction accuracy in the out of sample test. It is also worth noticing that altering coefficients and adjusting variables of the original z-score model could not significantly improve the predictive power of z-score model regarding companies in the industrial industry in the UK.

Published: December 2017

This study is aimed to get empirical evidence about the indications of behavior of follower investor in the formation of stock’s prices in the Indonesian Stock Exchange (BEI) when the event market crash occured. As well as aiming to analyze whether the behavior of follower investor can be called irrational behavior by looking at the difference in behavior of follower investor on each sector in IDX. This study uses secondary data in the form of stock’s closing price and Indonesia Composite Index (IHSG) companies listed on the BEI Stock Exchange during 2010-2013 by accessing the website www.idx.co.id, www.finance.yahoo.com, and www.ksei.co.id. Total populations are 507 companies, while the total samples are 350 companies. The analysis technique used is Cross-sectional Absolute Deviation (CSAD) to detect the behavior of follower investor in the formation of stock price and One Way ANOVA test with Post Hoc Test and Least Significant Difference (LSD) to analyze the irrationallity in follower investor’s behavior. The analysis showed that there were indications follower investor’s behavior in the stock’s price formation and proved that behavior of follower investor is an irrational behavior.
The Determinants of Sell-side Analysts’ Forecast Accuracy and Media Exposure
Authors: Sorogho Samira Amadu
Published: December 2017

This study examines contributing factors to the differential forecasting abilities of sell-side analysts and the relation between the sentiments of these analysts and their media exposure. In particular, I investigate whether the level of optimism expressed in sell-side analysts’ reports of fifteen constituents of primarily the S&P 500 Oil and Gas Industry1, enhance the media appearance of these analysts. Using a number of variables estimated from the I/B/E/S Detail history database, 15,455 analyst reports collected from Thompson Reuters Investext and analyst media appearances obtained from Dow Jones Factiva from 1999 to 2014, I run a multiple linear regression to determine the effect of independent variables on dependent variables.  I find that an analyst’s forecast accuracy (as measured by the errors inherent in his forecasts) is negatively associated with the analyst’s level of media exposure, experience, brokerage size, the number of times he revises his forecasts in a year and the number of companies followed by the analyst, and positively associated with the analyst’s level of optimism expressed in his reports, forecast horizon and the size of the company he follows.

Published: December 2017

This study aims to examine the effect of fiscal decentralization on gross regional domestic product (GRDP) of districts in South Sumatera. The data used in this study are secondary data in the form of GRDP, district expenditure to provincial expenditure ratio, district revenue to district expenditure ratio and balancing fund to district revenue ratio in 15 districts/cities in South Sumatera for 11 years during the period of 2005-2015. Multiple regression analysis on fixed effect model is used in analyzing the data. The result shows that simultaneosly, fiscal decentralisation has significant effect on GRDP of districits/cities in South Sumatera. However, in partial test, the district expenditure to provincial expenditure ratio is positive and insignificant. This is related to the district expenditure allocation that has not any direct impact on the district economy thus, it has yet to give results that can support the economic growth.

Published: December 2017

In the activity of the modern economy, the availability of money as a means of transaction is very important, because with the money as a means to pay consumers can easily to get the basic material needs are required, the manufacturer can provide the raw materials of labor for production, and distributors can obtain a variety of merchandise to be delivered at the end consumer. The pattern of use of money is influenced by the attitude of the public in the transaction. Researchers assume, that there are differences among communities, either by group differences in income, educational differences, ethnic differences, differences in profession, and perhaps even religious differences embraced. So as to provide information to the monetary authorities, to enrich the theory of demand for money based economic agents in Indonesia, and for the application of the theory of demand for money, the researchers felt the need to study patterns of use of money. Qualitative research, in addition to knowing whether the variables that affect the demand for money as the above theory is still relevant for economic actors in Indonesia at this time, or even are new variables, as well as the motive of money demand.Keywords: Demand for money, Keynes Theory, qualitative method
Comparative Analysis of Behavioural Response of Captive-Reared and Wild-Trapped Northern Bobwhites to Simulated Predator Attacks
Authors: Reyna Kelly S. , Newman William L.
Published: December 2017

Isolated populations of Northern Bobwhites (Colinus virginianus) have declined causing many landowners to attempt population restoration by releasing captive-reared birds. These attempts have resulted in high mortality rates, which we hypothesised are caused by captive-reared birds exhibiting more naïve predator avoidance behaviour than wild birds. Captive-reared and wild-trapped Northern Bobwhites were subjected to raptorial and terrestrial predator simulations and their responses were recorded on high definition video. We recorded the time to predator detection, time to anti-predator defence, and reaction type for comparative analysis. Captive-reared birds detected simulated predators quicker than wild-trapped birds, but time to mount an anti-predator defence was not different between groups. The response type, however, was different between groups. Captive-reared birds typically flushed when encountering a simulated predator; yet, wild-trapped birds did not flush at all, and typically ran or held when subjected to the simulated predators. We hypothesise that flushing is a naïve anti-predator response that results in revealing of position in the presence of a threat, thereby increasing the individual risk of predation. These results potentially illuminate at least one reason why captive-reared Northern Bobwhite releases have been largely unsuccessful.

Toxoplasma gondii is widely prevalent in most warm-blooded animals worldwide. This protozoan is transmitted to intermediate hosts through a variety of modes. Humans are mainly infected by eating undercooked or raw meat of birds or livestock and eating food or drinking water contaminated with oocysts. Our aim was to assess T. gondii antibodies in birds. Samples were collected from 335 free-range birds and 50 migrating birds from September 2014 to December 2015. T. gondii antibodies were assayed using the modified agglutination test (MAT). Seroprevalence were verified in 51.4% of 385 birds (MAT titer ≥ 1:20 was seen in 51.3% and 52% of domestic and migrating birds, respectively). Statistically significant differences were not observed among species of birds. Free-range chickens of the central region showed a higher positive level than those of the other regions. However, the study results showed that more than half of the birds in this area are infected with T. gondii and therefore, could be considered as one of the most important hosts and a potential threat for consumers.

Cet article vise à comprendre comment les cadres intermédiaires gèrent leurs rôles d’acteurs lors d’un plan de licenciement. Le cadre théorique du modèle transactionnel du stress est mobilisé auprès de 70 personnes interrogées (54 managers et 16 Professionnels en Ressources Humaines). En croisant l’orientation (salariés licenciés vs entreprise) et l’intensité (faible vs forte) de l’engagement, l’analyse fait ressortir 4 postures développées par les cadres intermédiaires pour tenir leur rôle d’acteur du plan de licenciement. Elle identifie également les ressources internes et externes mobilisées par le cadre dans ces ajustements. Dépassant les logiques explicatives unidimensionnelles survalorisant l’agent ou la structure, cette recherche précise les stratégies, tactiques et ressources utilisées et intègre les conséquences organisationnelles de la tenue du rôle d’acteur du licenciement par le cadre intermédiaire.
L’immersion du salarié dans une expérience de travail : conceptualisation et implications
Authors: Brillet Franck , Maubisson Laurent , Ndiaye Adama
Published: December 2017

L’immersion est un concept qui trouve ses fondements en psychologie positive et qui est actuellement mobilisé au sein des sciences de gestion par le marketing et les systèmes d’information. À partir de ces travaux et partant du constat que la gestion des ressources humaines ne s’y est pas encore intéressée, les auteurs proposent de considérer ce concept dans le cadre de situations de travail. Ainsi, un modèle conceptuel est proposé et une étude empirique conduite auprès de 311 employés a été réalisée. Les résultats permettent de donner une définition de ce concept en GRH et montrent un lien très étroit entre l’immersion dans une situation de travail et l’engagement ; lien toutefois modéré selon l’âge et l’ancienneté dans le poste.

Molecular Epidemiology of Nosocomial Infection: Analysis of chromosomal Restriction Fragment Patterns by Pulsed-Field Gel Electrophoresis
Authors: Shehata Afaf I , Al-Aidan Alwaleed A. , Al-Shahrani Buthainah
Published: December 2017

Acinetobacter baumannii is a species of non-fermentative gram-negative coccobacilli commonly found in soil, water and other environmental samples. This bacterium is defined as being strict aerobes, nonmotile, catalase-positive and oxidase-negative. This organism was susceptible to most antibiotics in the 1970s. A. baumannii is an opportunistic pathogen that may be an important threat due to its increasing multidrug resistance and is involved in nosocomial infections that are often severe. The objective of this study was undertaken to elucidate the molecular epidemiology of A. baumannii using the most widely applicable DNA – based typing methods namely Pulsed-Field Gel Electrophoresis (PFGE). These strains comprised isolates from environmental samples, blood, wound, urine, cerebrospinal fluid and tracheal aspirates. PFGE analysis of 81 clinical isolates has been carried out by using CHEF–DR III systems from Bio – Rad and following the protocol of Gautom with some modifications. A 2.00% band tolerance and an optimization of 4.00% were selected for use during comparisons of generated fingerprints or pulsotypes after digestion with Apa I restriction enzyme. Similarity values have been generated using BioNumerics software, cluster analysis was performed by the unweighted pair – group method using arithmetic averages and DNA relatedness was calculated based on Dice coefficient. An interlinkage homology level of 80% between patterns was assumed as the cutoff for defining a close genetic relationship between strains and was used to define the cluster. As per the generated dendogram, isolates were categorized into 18 major groups designated as Strain I to Strain xvIII. Overall, PFGE was able to discriminate the 81 different Acinetobacter baumannii isolates with similarity levels of 63.63%.

Abstract. We present the first direct measurements of NO3 reactivity (or inverse lifetime, s−1) in the Finnish boreal forest. The data were obtained during the IBAIRN campaign (Influence of Biosphere-Atmosphere Interactions on the Reactive Nitrogen budget) which took place in Hyytiälä, Finland during the summer/autumn transition in September 2016. The NO3 reactivity was generally very high with a maximum value of 0.94 s−1 and displayed a strong diel variation with a campaign-averaged nighttime mean value of 0.11 s−1 compared to a daytime value of 0.04 s−1. The highest nighttime NO3-reactivity was accompanied by major depletion of canopy level ozone and was associated with strong temperature inversions and high levels of monoterpenes. The daytime reactivity was sufficiently large that reactions of NO3 with organic trace gases could compete with photolysis and reaction with NO. There was no significant reduction in the measured NO3 reactivity between the beginning and end of the campaign indicating that any seasonal reduction in canopy emissions of reactive biogenic trace gases was offset by emissions from the forest floor. Observations of biogenic hydrocarbons (BVOC) suggested a dominant role for monoterpenes in determining the NO3 reactivity. Reactivity not accounted for by in-situ measurement of NO and BVOCs was variable across the diel cycle with, on average, circa 30 % “missing” during nighttime and circa 60 % missing during the day. Measurement of the NO3 reactivity at various heights (8.5 to 25 m) both above and below the canopy, revealed a strong nighttime, vertical gradient with maximum values closest to the ground. The gradient disappeared during daytime due to efficient vertical mixing.
The management of rectal bleeding following transrectal prostate biopsy: A review of the current literature
Authors: Quinlan Mark R. , Bolton Damien M. , Casey Rowan G.
Published: December 2017

Introduction: Since the advent of prostate-specific antigen (PSA)-based testing, transrectal ultrasound (TRUS)-guided prostate biopsy has become a standard part of the diagnostic pathway for prostate cancer (PCa). Rectal bleeding is one of the common side effects of this transrectal route. While rectal bleeding is usually mild and self-limiting, it can be life-threatening. In this article, we examine rectal bleeding post TRUS-guided prostate biopsy and explore the literature to evaluate techniques and strategies aimed at preventing and managing this common and important complication.Methods: A PubMed literature search was carried out using the keywords “transrectal-prostate-biopsy-bleed.” A search of the bibliography of reviewed studies was also conducted. Additionally, papers in non-PubMed-listed journals of which the authors were aware were appraised.Results: Numerous modifiable risk factors for this bleeding complication exist, particularly anticoagulants/antiplatelets and the number of core biopsies taken. Successfully described corrective measures for such rectal bleeding include tamponade (digital/packs/catheter/tampon/condom), endoscopic sclerotherapy/banding/clipping, radiological embolization, and surgical intervention.Conclusions: We advocate early consultation with the colorectal/gastroenterology and interventional radiology services and a progressive, stepwise approach to the management of post-biopsy rectal bleeding, starting with resuscitation and conservative tamponade measures, moving to endoscopic hemostasis ± radiological embolization ± transanal surgical methods. Given the infrequent but serious nature of major rectal bleeding after TRUS biopsy, we recommend the establishment of centralized databases or registries forthwith to prospectively capture such data. To the best of our knowledge, this is the first comprehensive look specifically at the management of post-TRUS biopsy rectal bleeding.
Trends in the training of female urology residents in Canada
Authors: Anderson Katherine , Tennankore Karthik , Cox Ashley
Published: December 2017

Introduction: There is limited research on why females do or do not choose a career in urology. Considering the increasing proportion of female medical students, we assessed for trends in female applicants to urology programs in Canada and their post-residency career choices.Methods: Data from the Canadian Residency Matching Service (CaRMS) was used (1998‒2015). Trends in the proportions of females applying and matching to surgical subspecialties, and applying and matching to urology were computed. Surveys were sent to urology program directors to assess female residents’ chosen career paths over the last decade.Results: A significant increasing trend in the proportion of females applying to urology as their first choice program was found (0.19 in 1998‒99 to 0.27 in 2012‒15; p=0.04). An increasing trend in the proportion of females successfully matching to urology was found, although it was not statistically significant (0.13 in 1998‒99 to 0.24 in 2012‒15; p=0.07). This was in keeping with the trends found for surgical programs overall. Female graduates choose a variety of career paths with urogynecology being the most common fellowship (26%).Conclusions: The last two decades has seen an increase in the proportion of female students applying to urology in Canada. Female urology graduates pursue a variety of career paths. It remains imperative that both female and male medical students have early exposure and education about our subspecialty to ensure we continue to recruit the most talented candidates.

Published: December 2017

Introduction: The objective of this study was to compare fragmentation efficiency of the conventional regular mode of holmium laser to the Moses contact mode on a stone simulator.Methods: The Lumenis® PulseTM P120 H holmium laser system, together with Moses D/F/L fibers were used to compare regular mode with Moses contact mode in a stone simulator model using flexible ureteroscopy with artificial stones. Efficiency of laser lithotripsy was measured by procedural time. Degree of stone retropulsion was also compared between regular and Moses modes using a Likert scale from 0 (no retropulsion) to 3 (maximum retropulsion).Results: Using the stone simulator model, a significant reduction in stone retropulsion was noticed when comparing regular mode to the Moses contact mode (mean Grade 2.5 vs. Grade 1; p<0.01). When compared with the regular mode, the Moses contact mode was associated with significantly shorter procedural time during fragmentation (13.9 vs. 9.1 minutes; p≤0.01) and dusting (9.3 vs. 7.1 minutes; p≤0.01). In addition, when compared with the regular mode, the laser pedal was pressed significantly less often with the Moses mode during fragmentation (86 vs. 43 times; p<0.01) and dusting (50 vs. 26 times; p<0.01). Moses contact mode was associated with significantly higher percentage of lasing vs. pausing when compared with the regular mode for both fragmentation (0.8 J/10 Hz) and pulverization (0.4 J/50 Hz) settings (both p<0.05).Conclusions: Using the stone simulator setup, Moses technology was associated with more efficient laser lithotripsy (shorter operative time) due to significantly reduced stone retropulsion.

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy of the adrenal cortex. Complete surgical resection is essential for localized tumours because ACC is highly resistant to chemotherapy and radiotherapy.1 Use of a laparoscopic approach for adrenalectomy in the setting of a confirmed or suspected ACC is controversial because it is unknown if laparoscopy provides equivalent oncological outcomes compared to an open approach.

Evaluation of Diluted Cellulose Solutions for Nanofiber Production using the Electrospinning Method
Authors: Łaszkiewicz Bogumił , Kulpiński Piotr , Stanisławska Anna
Published: December 2017

This paper discusses the possibility of nanofibre formation in an electrostatic field from cellulose solutions in different solvent systems. Additionally when investigating solutions of various cellulose content, an attempt was made to evaluate these solutions from the viewpoint of their usability for nanofibre formation. The spinnability of the solutions examined was assessed based on observation of the stability of nanofibre formation by the simplest single needle spinning device. The morphology of the samples obtained by electrospinning was studied by Scanning Electron Microscopy (SEM). Spinning dopes were obtained using well-known technologies for cellulose solution preparation applied in the cellulose fibre industry, namely N-Methylmorpholine N-oxide (NMMO) and viscose methods, as well as a mixture of phosphoric acids, which is relatively cheap, easily available and yet not used in industry. Based on the research conducted, it may be concluded that the cellulose solutions in NMMO proved to be the best system for exceptionally stable formation of nanofibres in an electrostatic field.

Influence of the Bamboo/Cotton Fibre Blend Proportion on the Thermal Comfort Properties of Single Jersey Knitted Fabrics
Authors: Kadapalayam Chinnasamy Karunakaran , Chidambaram Prakash
Published: December 2017

The main aim was to find out the influence of the blend ratio and linear density on the thermal comfort properties of regenerated bamboo cotton blended single jersey knitted fabrics. An increase in the regenerated bamboo fibre ratio in the fabric influences the thermal comfort properties. Knitted fabrics prepared from regenerated bamboo blended yarns have lesser thickness and inferior mass per square meter than cotton fabrics. The proportion of regenerated bamboo fibre increases in the yarn as the value of thermal conductivity decreases in knitted fabrics. Water vapour permeability and air permeability confirm a similar increase as the proportion of regenerated bamboo fibre increases. 100% regenerated bamboo fabrics have superior air permeability values compared with regenerated bamboo/cotton blended fabrics. The statistical investigation also showed that the results are significant for the thermal comfort properties of regenerated bamboo cotton knitted fabrics.

Authors: Grgac Sandra Flinčec , Bischof Sandra , Pušić Tanja , Petrinić Irena , Luxbacher Thomas
Published: December 2017

Fabric flammability is affected by various factors such as the fibre composition, fabric construction, FR (flame retardant) finish, oxygen concentration and environmental conditions (moisture content, heat.). Inherently FR fabrics are synthetics which have been changed at the molecular level to make the fabrics thermally stable and able to pass FR tests. The thermal properties of knitted fabrics produced from cotton, modacryl and their blends were investigated in this paper. The design of FR knitted fabrics and an optimal blend ratio were evaluated by different thermoanalytical methods: the flame behaviour and thermal stability with the limited oxygen index (LOI), thermal gravimetric analysis (TGA), coupled thermal gravimetry - Fourier transform infrared technique (TG-FTIR) and microscale combustion calorimetry (MCC). Surface characterisation of the knitted fabrics designed was evaluated by the streaming potential method. Knitted fabric in the blend ratio C50:M50 proved to possess the most favourable FR characteristics, additionally confirmed by optimal hydrophilic properties evaluated through zeta potential measurement.
Energy Release Studies of Human Feet for Mapping µPCM Quantity in Socks for Thermoregulation
Authors: Siddhan Periyasamy , Jayakumar Balaji
Published: December 2017

Pure PCM and microencapsulated PCM (µPCM) were analysed for heat capacity and core content using DSC analysis and were tested for stability against heat and solvent. The energy release rate of human feet was quantified through a novel in-house tester using a water and air medium. The energy release rate from various experiments were compared and ranges of the quantity of µPCM recommended for a definite period of thermoregulation with and without a factor of safety. Based on theoretical predictions, socks were treated with µPCM at add-on values of 0.2 g to 5 g corresponding to 1% and 25 % per weight of the socks, respectively. The socks treated were subjected to wear trials and evaluated against the untreated one. It was found that the thermoregulation period of the µPCM treated socks were proportional to their add-on weight and were in close agreement with the theoretical predictions proposed. The presence of µPCM on the treated socks was observed through a scanning electron microscope.
Study on the Effects of Perfume on the Mechanical and Colour Properties of Silk Fabrics
Authors: Krishnamoorthi Kavitha , Jagannathan Srinivasan
Published: December 2017

Perfumes are generally used to enhance the attitude of the person. Deodorants and perfumes are designed to be applied directly to the skin. Some people with sensitive skin may find that their skin does get irritated if they use too much perfume and hence apply perfume directly to their clothes. Silk is one of the most luxurious fabrics and is used on all occasions. If perfume is applied directly on fabric, it may cause a stain or discoloration and may spoil a costly garment. Although there is a study on the effect of perfume on cotton fabrics, there is no study about the effect of perfume on silk fabrics in the literature. Therefore this study aims to investigate the effects of perfume on dyed silk fabrics and is the first work on this subject. Mechanical properties like tensile strength, pilling and abrasion resistance were investigated, and the change in colour under washing, dry cleaning and perspiration were recorded.

Published: December 2017

Achieving efficient bulk‐heterojunction (BHJ) solar cells from blends of solution‐processable small‐molecule (SM) donors and acceptors is proved particularly challenging due to the complexity in obtaining a favorable donor–acceptor morphology. In this report, the BHJ device performance pattern of a set of analogous, well‐defined SM donors—DR3TBDTT (DR3), SMPV1, and BTR—used in conjunction with the SM acceptor IDTTBM is examined. Examinations show that the nonfullerene “All‐SM” BHJ solar cells made with DR3 and IDTTBM can achieve power conversion efficiencies (PCEs) of up to ≈4.5% (avg. 4.0%) when the solution‐processing additive 1,8‐diiodooctane (DIO, 0.8% v/v) is used in the blend solutions. The figures of merit of optimized DR3:IDTTBM solar cells contrast with those of “as‐cast” BHJ devices from which only modest PCEs <1% can be achieved. Combining electron energy loss spectrum analyses in scanning transmission electron microscopy mode, carrier transport measurements via “metal‐insulator‐semiconductor carrier extraction” methods, and systematic recombination examinations by light‐dependence and transient photocurrent analyses, it is shown that DIO plays a determining role—establishing a favorable lengthscale for the phase‐separated SM donor–acceptor network and, in turn, improving the balance in hole/electron mobilities and the carrier collection efficiencies overall.

The use of heterogeneous bimetallic Pd‐based nanocatalyst for directing the inactivated sp3 C−H coupling has been scarcely explored. This work reported the formation of symmetrical C−C bonds from the inactivated sp3 C−H bonds catalyzed by employing reduced graphene oxide supported PtPd@Pt porous nanospheres. The reaction of sp3 C−H activation proceeded under mild conditions without any solvent, ligand or directing group. It is a higher atom‐, step‐ and cost‐effectiveness strategy for developing heterogeneous catalysts in the synthesis of bibenzyls with various functional groups (e. g. aryl, alkyl, methoxyl, halogen, ester, and pyridyl).

In the present work, an asymmetric copper‐catalyzed radical multi‐component cascade reaction of an unsaturated carboxylic acid, aryldiazonium tetrafluoroborate, and DABCO⋅(SO2)2 (DABSO) has been developed for the enantioselective synthesis of sulfonyl lactones. In this reaction, this SO2 surrogate, DABSO was applied for the first time in the construction of chiral compounds. This multiple‐step asymmetric radical reaction was carried out under mild conditions and tolerated a wide range of substrates, resulting in the corresponding sulfonyl lactones with up to 95% chemical yields and 88% ee. The current reaction enriches the research contents of DABSO, and provides a new and efficient strategy to chiral functionalized lactones bearing quarternary stereogenic center.

Published: December 2017

Micellization brought about by nonclassical hydrophobic effect invokes enthalpy as the driving force. Thus, the underlying molecular phenomena differ from the entropically dominated hydrophobic effect. In quest for a molecular‐scale understanding, we report on the molecular arrangement of nonamphiphilic structures of an anionic boron cluster compound, COSAN. We synergistically combine experimental (NMR and calorimetry) and theoretical (molecular dynamics and quantum chemical calculations) approaches. The experimental data support the mechanism of closed association of COSAN, where the self‐assembly is driven by the enthalpy contribution to the free energy. Molecular dynamics simulations in explicit solvent show that water molecules form a patchy network around COSAN molecules, giving rise to the strong hydrophobic self‐association. In the second solvation shell, water forms a slightly hydrophilic “spot” close to the C‐H segments of the cluster. The simulations further show a counterintuitive short‐range [COSAN]−∙∙∙[COSAN]− attraction and Na+∙∙∙[COSAN]− repulsion. Quantum chemical calculations reveal a major role of solvation in stabilizing the contact pairs. Further, the calculations show the parallel/X‐shape geometrical arrangements of COSAN dimers as the most preferred. Lastly, dihydrogen bonding are found to influence the structure of micelles. In summary, we provide a molecular view of nonclassical micellization that can be extended to other amphiphiles like boranes.

Objective

Mixed neuropathologies are the most common cause of dementia at the population level, but how different neuropathologies contribute to cognitive decline at the individual level remains unknown. We quantified the contribution of 9 neuropathologies to cognitive loss at an individual level.

Methods

Participants (n = 1,079) came from 2 longitudinal clinical–pathologic studies of aging. All completed 2 + cognitive evaluations (maximum = 22), died, and underwent neuropathologic examinations to identify Alzheimer disease (AD), other neurodegenerative diseases, and vascular pathologies. Linear mixed models examined associations of neuropathologies with cognitive decline and estimated the proportion of cognitive loss accounted for by each neuropathology at a person‐specific level.

Results

Neuropathology was ubiquitous, with 94% of participants having 1+, 78% having 2+, 58% having 3+, and 35% having 4+. AD was most frequent (65%) but rarely occurred in isolation (9%). Remarkably, >230 different neuropathologic combinations were observed, each of which occurred in <6% of the cohort. The relative contributions of specific neuropathologies to cognitive loss varied widely across individuals. Although AD accounted for an average of about 50% of the observed cognitive loss, the proportion accounted for at the individual level ranged widely from 22% to 100%. Lewy bodies and hippocampal sclerosis also had potent effects, but again their impacts varied at the person‐specific level.

Interpretation

There is much greater heterogeneity in the comorbidity and cognitive impact of age‐related neuropathologies than currently appreciated, suggesting an urgent need for novel therapeutic approaches that embrace the complexity of disease to combat cognitive decline in old age. Ann Neurol 2018;83:74–83
The Wisdom of the Body and Couple Therapy – A Sensorimotor Psychotherapy Perspective: An Interview with Pat Ogden
Authors: Masero Monica
Published: December 2017

Sensorimotor psychotherapy (SP) is used for the treatment of trauma and attachment challenges. It is informed by interpersonal neurobiology, trauma, and attachment research blending theory and techniques from cognitive, affective, and psychodynamic therapy with somatic interventions. In SP, the body is the target of therapeutic interventions. By bringing sensorimotor processes into awareness using both cognitive (top‐down) and sensorimotor (bottom‐up) processes this approach aims to interrupt autonomic somatic narratives embedded in procedural memory. These adaptive patterns can impact abilities in affect regulation and relational interactions and can sustain adaptive internal working models that may be stuck in the past, resulting from trauma and attachment inadequacies. SP utilises interventions at both the somatic and verbal level: relational proximity‐seeking movements, postures, gestures, eye contact; prosody, facial expressions; verbal actions such as saying ‘no.’ These interventions can increase arousal regulation or co‐regulation capacities to create change at cognitive, affective, and somatic levels. This interview with Dr Pat Ogden, PhD, explores how SP and in particular the body can be incorporated into work with couples.
The Trauma Healing Story. Healing Chronically Traumatised Children Through Their Families/Whanau
Authors: Struik Arianne
Published: December 2017

Unprocessed trauma can have a devastating impact on all areas of development (Van der Kolk et al., 2009). Chronically traumatised children can be difficult to engage in trauma‐focused treatment, especially when they are removed from their families by child protection services feeling blamed and disconnected. They display challenging behaviour, move from foster family to foster family, abscond, engage in criminal activities, use drugs and do not attend school. Their parents are often responsible for the abuse and families/whanau suffer from the consequences of intergenerational trauma. Instead of distancing the child from these ‘dysfunctional families,’ the trauma healing story intervention views intensive collaboration with the child's parents and family as the key to engaging these children. The child's life story is described and illustrated with simple drawings in which the parents acknowledge the child's innocence and explain their intentions. Children can start to understand they were not responsible for the abuse and feel their parents’ permission to talk about their traumatic memories. Creating a mutual narrative of what happened reconnects parents and children, and parents can encourage their children to participate in consecutive trauma‐focused therapy. The process of constructing this story with the parents provides them with an opportunity to heal from intergenerational trauma as well and break the cycle of intergenerational abuse. This article describes the Trauma Healing Story intervention, illustrated with case examples. The Trauma Healing Story intervention is part of the Sleeping Dogs method, developed for resistant chronically traumatised children with promising results. Clinical experience has also demonstrated that the structured format of the Trauma Healing Story intervention accommodates a Fly‐In‐Fly‐Out delivery model of specialised trauma‐focused treatment in remote areas in Australia and New Zealand.
Conceptual metaphors shape consumer psychology
Authors: Landau Mark J. , Zhong Chen‐bo , Swanson Trevor J.
Published: December 2017

Marketers routinely use metaphors to compare abstract concepts to concrete concepts in remote domains. For example, a tagline “Supercharge your day” compares energy to electricity. Such messages aim to change consumer attitudes and behavior, but what impact do they have? According to Conceptual Metaphor Theory, metaphors can shape thought by borrowing knowledge of a concrete concept to understand and relate to an abstraction, despite their superficial differences. Supporting this claim is growing evidence that exposure to metaphoric messages prompts recipients to construe the metaphor's abstraction in ways that are analogous to the salient concrete concept. This article presents a selective review of this literature, focusing on studies pertaining to product evaluation and consumption attitudes. Discussion looks across findings to identify questions for future research. Taken as a whole, this research illuminates how, when, and for whom metaphoric messages are persuasive, with theoretical and practical implications for marketing, design, and persuasion.

Published: December 2017

A batch experiment is conducted to evaluate the influence of root exudates on the removal of triclosan (TCS) in soil samples under aerobic and anaerobic conditions. The BIOLOG method and quantitative real‐time PCR (qPCR) is used to analyze the microbial metabolic characteristics and bacterial absolute abundance, respectively. The results shows that TCS is removed relatively faster in aerobic groups than anaerobic ones, especially in the aerobic group with artificial root exudates solution (ARES) addition. However, no difference can be seen in TCS removal performance between anaerobic groups with or without ARES addition (p > 0.05). The results of BIOLOG show that the average metabolic activity of microorganisms (AWCD) increases significantly in the aerobic group with ARES addition with time, followed by the aerobic control group and anaerobic groups. The carbon source utilization behavior of soil microbes exhibit significant differences. Carbohydrates can be utilized easily in the aerobic group with ARES addition, while the fractional content of amines in the anaerobic group with ARES is highest. Furthermore, bacterial abundance shows positive correlation with the TCS removal under aerobic conditions. Overall, ARES addition can greatly promote the removal efficiency of TCS under aerobic conditions, but have a small effect under anaerobic conditions.
