Keeping the PEACE? A study of investigative interviewing practices in the public sector
Authors: Walsh David W. , Milne Rebecca 
Published: October 2006

Purpose. This study examined the interviewing ability of benefit fraud investigators, specifically examining the effects of training in the PEACE model. This model, preferred by the British police, is a mnemonic for the interview process: planning and preparation, engage and explanation, account, closure, and evaluation.Methods. An analysis was undertaken of 99 audiotapes of real‐life interviews with benefit fraud suspects, comparing performance levels between trained and untrained investigators, using an assessment scale consisting of 56 behavioural and procedural elements adapted from Clarke and Milne (2001).Results. Some improvements were found in performance amongst the trained investigators notably with good practices being seen in the effective use of ‘open’ questions which facilitated increased information from suspects, in addition to a comprehensive fulfilment of the necessary legal requirements. Additionally, only rare occurrences were found of any unethical practices. However, the study also found little evidence of planning which was thought to affect interview content particularly in relation to their structure and flexibility. Concerns were also found with (i) shortfalls in rapport building, (ii) insufficient coverage of the points that required proving, (iii) failures to completely explore the suspect's motive and (iv) the lack of summarizing during the interview.Conclusions. The research found some performance improvement after interview training but this was insufficient to suggest a general trend towards increased professionalism. A need for further training was identified, both in the PEACE model and in other appropriate interviewing skills.

Published: October 2006

Abstract
Nutrition influences peak bone mass development in early adulthood. The effect of high dietary phosphate intake on the growing skeleton of 1-month-old male rats (n = 30) was assessed in an 8-week intervention. High dietary phosphate intake increased bone remodeling and impaired bone material properties, diminishing bone mechanical strength.
Introduction: High dietary phosphate intake is typical in the Western diet. Abundant phosphate intake enhances parathyroid secretion and bone metabolism. To study the influence of high dietary phosphate intake on growing bone homeostasis and structure, we submitted growing rats to experimental diets that varied in their phosphate content.
Materials and Methods: One-month-old intact male rats (n = 30) were fed a control diet (Ca:P 1:1) or an experimental diet of either Ca:P 1:2 or Ca:P 1:3 for 8 weeks. At the beginning and the end of the study period, the right femurs were measured using DXA. Double labeling with tetracycline injection was performed 12 and 2 days before death. After death, hind legs were cut loose. Left femurs were processed for histomorphometry. Right femurs were measured with pQCT. Mechanical testing was performed on the right femoral neck and tibial shaft. Six right tibias were analyzed with μCT. Serum PTH, calcium, and phosphate contents were analyzed.
Results: High-phosphate intake impaired growth of the animal, limited bone longitudinal growth, and restricted femur BMC and BMD build-up. Osteoclast number, osteoblast perimeter, and mineral apposition rate were increased, and trabecular area and width were decreased. Phosphate decreased femur midshaft total bone BMD, cortical bone BMD, and mean cortical thickness. High-phosphate diet reduced femoral neck and tibial shaft ultimate strength and tibia stiffness and toughness. In addition, serum PTH increased.
Conclusions: High dietary phosphate intake reduced growth, skeletal material, and structural properties and decreased bone strength in growing male rats. Adequate calcium could not overcome this.
Effects of Teriparatide and Alendronate on Vertebral Strength as Assessed by Finite Element Modeling of QCT Scans in Women With Osteoporosis

Published: October 2006

Abstract
FE modeling was used to estimate the biomechanical effects of teriparatide and alendronate on lumbar vertebrae. Both treatments enhanced predicted vertebral strength by increasing average density. This effect was more pronounced for teriparatide, which further increased predicted vertebral strength by altering the distribution of density within the vertebra, preferentially increasing the strength of the trabecular compartment.
Introduction: Teriparatide 20 μg/day (TPTD) and alendronate 10 mg/day (ALN) increase areal, measured by DXA, and volumetric, measured by QCT, lumbar spine BMD through opposite effects on bone remodeling. Using finite element (FE) modeling of QCT scans, we sought to compare the vertebral strength characteristics in TPTD- and ALN-treated patients.
Materials and Methods: A subset of patients (N = 28 TPTD; N = 25 ALN) from the Forteo Alendronate Comparator Trial who had QCT scans of the spine at baseline and postbaseline were analyzed. The QCT scans were analyzed for compressive strength of the L3 vertebra using FE modeling. In addition, using controlled parameter studies of the FE models, the effects of changes in density, density distribution, and geometry on strength were calculated, a strength:density ratio was determined, and a response to bending was also quantified.
Results: Both treatments had positive effects on predicted vertebral strength characteristics. At least 75% of the patients in each treatment group had increased strength of the vertebra at 6 months compared with baseline. Patients in both treatment groups had increased average volumetric density and increased strength in the trabecular bone, but the median percentage increases for these parameters were 5- to 12-fold greater for TPTD. Larger increases in the strength:density ratio were also observed for TPTD, and these were primarily attributed to preferential increases in trabecular strength.
Conclusions: These results provide new insight into the effects of these treatments on estimated biomechanical properties of the vertebra. Both treatments positively affected predicted vertebral strength through their effects on average BMD, but the magnitudes of the effects were quite different. Teriparatide also affected vertebral strength by altering the distribution of density within the vertebra, so that overall, teriparatide had a 5-fold greater percentage increase in the strength:density ratio.
Craniosynostosis-Associated Gene Nell-1 Is Regulated by Runx2

Published: October 2006

Abstract
We studied the transcriptional regulation of NELL-1, a craniosynostosis-related gene. We identitifed three OSE2 elements in the NELL-1 promoter that are directly bound and transactivated by Runx2. Forced expression of Runx2 induces NELL-1 expression in rat calvarial cells.
Introduction: We previously reported the upregulation of NELL-1 in human craniosynostosis and the overexpression of Nell-1 in transgenic animals that induced premature suture closure associated with increased osteoblast differentiation. To study the transcriptional regulation of NELL-1, we analyzed the 5′ flanking region of the human NELL-1 gene. We identified three osteoblast specific binding elements 2 (OSE2) sites (A, B, and C) within 2.2 kb upstream of the transcription start site and further studied the functionality of these sites.
Materials and Methods: An area of 2.2 kb and a truncated 325 bp, which lacked the three OSE sites, were cloned into a luciferase reporter gene, and co-transfected with Runx2 expression plasmid. The three OSE2 sites were individually mutated and co-transfected with Runx2 expression plasmid into Saos2 cells. Gel shifts and supershifts with Runx2 antibodies were used to determine specific binding to OSE2 sites. CHIP assays were used to study in vivo binding of Runx2 to the Nell-1 promoter. Runx2 expression plasmid was transfected into wildtype and Runx2−/− calvarial cells. Nell-1, osteocalcin, and Runx2 expression levels were measured using RT-PCR.
Results: Addition of Runx2 dose-dependently increased the luciferase activity in the human NELL-1 promoter-luciferase p2213. The p325 truncated NELL-1 construct showed significantly lower basal level of activity. Nuclear extract from Saos2 cells formed complexes with site A, B, and C probes and were supershifted with Runx2 antibody. Mutation of sites A, B, and C significantly decreased basal promoter activity. Furthermore, mutation of sites B and C had a blunted response to Runx2, whereas mutation of site A had a lesser effect. Runx2 bound to NELL-1 promoter in vivo. Transfection of Runx2 in rat osteoblasts upregulated Nell-1 and Ocn expression, and in Runx2 null calvarial cells, both Nell-1 and Ocn expression were rescued.
Conclusions: Runx2 directly binds to the OSE2 elements and transactivates the human NELL-1 promoter. These results suggest that Nell-1 is likely a downstream target of Runx2. These findings may also extend our understanding of the molecular mechanisms governing the pathogenesis of craniosynostosis.
Humor styles, peer relationships, and bullying in middle childhood
Authors: Klein Dana N , Kuiper Nicholas A 
Published: October 2006

AbstractContemporary approaches to understanding humor have developed models that underscore the importance of both adaptive and maladaptive humor styles. The expression of these humor styles can then impact either positively or negatively on the self or others. One such model, as recently proposed by Rod Martin and his colleagues, outlines four distinct humor styles; namely self-enhancing, affiliative, self-defeating, and aggressive humor. Several studies with both adults and older adolescents provide initial empirical support for this model, including the adaptive aspects of self-enhancing and affiliative humor, as well as the maladaptive components of self-defeating and aggressive humor. However, these four humor styles have yet to be considered with respect to children. As such, the present paper considers how these different humor styles may bear on peer relationships and bullying during middle childhood (ages 6–12). In our examination, we describe how adaptive and maladaptive humor styles may either help or hinder the child's status within a peer group. Special emphasis is directed towards potential relationships between specific humor styles and either peer acceptance or victimization, as well as both direct and indirect forms of bullying. We conclude by describing several potential areas of research that may prove beneficial in furthering our understanding of humor and social relationship issues in middle childhood.
Cover Picture: Controlled Encapsulation of Hydrophobic Liquids in Hydrophilic Polymer Nanofibers by Co‐electrospinning (Adv. Funct. Mater. 16/2006)
Authors: Díaz J. E. , Barrero A. , Márquez M. , Loscertales I. G. 
Published: October 2006

AbstractThe cover shows an optical image of co‐electrospun nanofibers of poly(vinyl pyrrolidone) (outside) and hydrophobic oil (inside), irradiated by UV light. The resulting non‐woven mats present monosized beads regularly distributed along the nanofibers in work reported by Loscarteles and co‐workers on p. 2110. Only the beads fluoresce, due to special markers added to the oil, indicating that the oil is indeed wholly encapsulated inside the beads.There are many technical situations, such as various biological or medical applications, in which a hydrophobic fluid must be encapsulated inside a hydrophilic polymer shell in the form of tiny microscopic pieces. A novel approach is presented, based on the co‐electrospinning of the hydrophilic polymer melt (outside) and the hydrophobic fluid (inside), which results in beaded micro‐ and nanofibers, such that the hydrophobic fluid is efficiently encapsulated inside the beads. For the selected fluid couple, the low liquid–liquid surface tension and the high viscosity of the melt prevent the varicose break‐up of inner fluid in the coaxial electrified jet until the very end of the co‐electrospinning process. The resulting fibers present beads filled with the hydrophobic fluid, separated by a rather uniform distance whose length depends partially on the melt flow rate. The bead diameter grows with the inner flow rate, going from a monosized to a bisized distribution. In the case under study, the maximum relative (inner‐to‐outer) flow rate is one. The diameter of the solid fibers between beads scales well with existing theories for simple electrospinning.
Eicosanoid biosynthesis inhibitors influence mortality of Pieris brassicae larvae co‐injected with fungal conidia
Authors: Tunaz Hasan 
Published: October 2006

AbstractInfluence of fungal species (conidia spores) on mortality of Pieris brassicae larvae differed when injected into the larvae. The effects of B. bassiana (ARSEF‐1151) were expressed in a conidial dose‐dependent manner on mortality of the larvae. An increased and faster mortality of the larvae followed B. bassiana (ARSEF‐1151) infection when the spores were co‐injected with the eicosanoid biosynthesis inhibitors (dexamethasone, naproxen, phenidone, esculetin). These compounds express different modes of action. These lethal effects were reversed when dexamethasone was injected with eicosanoid precursor arachidonic acid (20:4n‐6). Nodulation is the predominant cellular reaction to bacterial and fungal injection in insects. Injection of each of five fungal species showed that nodulation intensity varies according to infecting fungal species. These findings support the idea that virulent effects of entomopathogenic, fungal species can be increased when P. brassicae immune systems are suppressed. Arch. Insect Biochem.

AbstractBei der Umsetzung N‐tertiärer Basen des 1‐Phenyl‐3‐amino‐propanol(1)‐Typs mit Natrium‐metaperjodat sind zwei Reaktionswege realisiert:1. Die Bildung des entsprechenden Aminoxids. 2. Die unspezifische Dehydrierung über die Imoniumstufe zu sekundärem Amin und Carbonsäure.Beide Umsetzungen sind auch bei N‐tertiären Phenyläthylaminen festzustellen. Damit ist gesichert, daß für den Reaktionsverlauf die Aminfunktion allein, ohne die Mitwirkung der Hydroxylgruppe verantwortlich ist.

AbstractPrimäre und sekundäre vinyloge Carbonsäureamide 1 reagieren mit Phenylisocyanat unter Bildung der Harnstoffe 2, nur die primären bilden mit Chloral die Addukte 4, deren Acetylierung zu den Estern 5 führt.Sekundäre vinyloge Carbonsäureamide, deren Vinylprotonen nicht substituiert sind, reagieren mit Chloral am Cα zu den Addukten 7, deren Acetylierung die Ester 8 liefert. Tertiäre vinyloge Carbonsäureamide des Typs 9 reagieren mit Chloral an der Methylgruppe am Cβ unter Bildung der Addukte 10, deren Umsetzung mit Phenylisocyanat zu den Urethanen 11 führt.Formaldehyd und Benzaldehyd bilden mit primären und sekundären vinylogen Carbonsäureamiden über die Addukte 12 die Methylen‐bisverbindungen 13, die unter Aminabspaltung in Dihydropyrinderivate 14 übergehen. Durch trans‐ständige Anordnung der Vinylprotonen charakterisiertes 15 ist in die N‐Hydroxymethyl‐verbindung 16 zu überführen.
