Effect of a DVD Intervention on Therapists’ Mental Health Practices With Older Adults
Authors: Lysack Cathy , Lichtenberg Peter , Schneider Brooke 
Published: May 2011

Abstract
PURPOSE. We tested the effectiveness of an educational intervention in DVD format aimed at strengthening the mental health practices of occupational therapists working with older adults.
METHOD. The DVD intervention was tested in a pretest–posttest design. Occupational therapists (n = 30) completed a brief knowledge and attitude questionnaire; a chart review (n = 383) of therapists’ (n = 20) patients at 3 mo before and 3 mo after DVD training was also conducted.
RESULTS. Questionnaire data showed that the percentage of therapists with correct answers increased 20%–30% for 5 of the 11 knowledge items. Chart review data showed therapists spoke more often with their older patients about mood, depression, and cognitive impairment; screened more often for depression and cognitive impairment; and reported findings more often to the treatment team after training.
CONCLUSION. Educational interventions can significantly improve therapists’ mental health practice with older adults.

Abstract
OBJECTIVE. We retrospectively assessed the effect of social-, cognitive-, and task-oriented functioning levels at hospital discharge on the readmission rate of patients with schizophrenia.
METHOD. We assessed the functional capability of 71 inpatients (37 men and 34 women), mean age 41.3 (standard deviation = 11.9 yr), who underwent daily occupational therapy interventions, at admission and at discharge using a comprehensive function score. We examined readmission rates up to 6.8 yr after discharge.
RESULTS. Function scores improved significantly during the hospital stay (p &lt; .001). Patients with a higher comprehensive function score (75th percentile) at the end of the index admission had a significantly lower readmission rate (p &lt; .05). A higher comprehensive function score (75th percentile) at discharge was a better predictor for readmission than the Brief Psychiatric Rating Score (25th percentile).
CONCLUSION. These findings demonstrate the predictive value of occupational therapy functional monitoring at discharge for risk of readmission and the importance of cognitive/functional interventions for long-lasting remission.
The reality of management development in SMEs
Authors: Coetzer Alan , Battisti Martina , Jurado Tanya , Massey Claire 
Published: May 2011

AbstractThe literature suggests that improving the management skills of owner-managers of SMEs contributes to their survival and growth and that there is considerable scope for further improvement in skills. However, evidence suggests that current support for management development (MD) does not meet the needs of SMEs. Nevertheless, there have been few changes on the supply side with policy makers continuously being concerned about low take-up of training. This study contributes to an understanding of how existing MD activities in SMEs can be better supported. Using Mumford's (1987) typology of MD activities to classify our interview data, findings from interviews with 25 owner-managers suggest two approaches to providing learning support: (1) incorporate structured opportunities for individual reflection and reflection within groups; and (2) address participants' concerns about training and mentoring. These findings have implications for policy makers and are timely given the current economic situation, where previous patterns of growth are being challenged and new ways of supporting MD in SMEs need to be found.
Radical and incremental entrepreneurial orientation: The effect of knowledge acquisition
Authors: Bojica Ana Maria , Fuentes Maria del Mar , Gómez-Gras José María 
Published: May 2011

AbstractA firm's collaborative context can represent an important source of knowledge for sustaining its entrepreneurial outcomes. Drawing on entrepreneurship and resource-based view literature, we study how the acquisition of knowledge from inter-firm ties affects the relationship between entrepreneurial orientation and performance, distinguishing between two types of knowledge, market and technological, and between two types of entrepreneurial orientation, radical and incremental. The results of the study on a sample of 203 Spanish small businesses from the Information and Communication Technology (ICT) sector suggest that knowledge acquisition plays different roles, depending on the type of entrepreneurial orientation developed and also on the type of knowledge exchanged. In particular, market and technological knowledge acquisition positively moderate only the relationship between radical entrepreneurial orientation and performance, while in the case of incremental entrepreneurial orientation we find only a direct positive influence of market knowledge acquisition on performance.
Social power as a means of increasing personal and organizational effectiveness: The mediating role of organizational citizenship behavior
Authors: Jain Ajay K , Giga Sabir I , Cooper Cary L 
Published: May 2011

AbstractThis study focuses on to explore the impact of social power on organizational citizenship behavior (OCB) and the role of OCB as a mediator of the relationship between social power and personal and organizational effectiveness. Data were collected by administering self rated questionnaires to male middle-level executives (N = 250) in face to face conditions from motor cycle manufacturing organisations based in northern India. The mediator analysis (by using AMOS) showed that all the fit indexes were in the acceptable range which indicates that OCBs have mediated significantly between social power and effectiveness. Other results as analyzed through multiple regression analysis showed the significant impact of social power on the dimensions of OCB and effectiveness as it was hypothesized. The study suggests the potential benefits of using positive forms of social power by supervisors as part of their managerial style in order to enhance OCBs and in turn increase personal and organizational effectiveness. This study advances the research on the concept of OCB and social power in an Indian work context.
The Effects of Alcohol on Crime‐related Memories: A Field Study
Authors: van Oorsouw Kim , Merckelbach Harald 
Published: May 2011

SummaryThis field study investigated to what extent memory of criminally relevant details is affected at (close to) zero (MBAC = 0.00%), moderate (MBAC = 0.06%), and high (MBAC = 0.16%) levels of alcohol intoxication. Participants (N = 76) were approached in bars and were invited to watch a mock crime from a perpetrator perspective. We also measured their blood alcohol concentration levels. After 3–5 days, when participants were sober, they underwent a free and cued recall task about the mock crime. Compared with sober controls, both moderately and highly intoxicated individuals were less complete when recollecting crime details, recalling up to 33% fewer correct details. Overall, intoxicated participants were less accurate during the cued recall task (i.e. they produced more errors) relative to sober participants. These accuracy effects were dose‐dependent for cued recall of salient features. Implications for police interrogations of defendants are discussed. Copyright © 2011 John Wiley & Sons, Ltd.
Bayesian estimation of dynamic finite mixtures
Authors: Nagy I. , Suzdaleva E. , Kárný M. , Mlynářová T. 
Published: May 2011

AbstractThe paper introduces an algorithm for estimation of dynamic mixture models. A new feature of the proposed algorithm is the ability to consider a dynamic form not only for component models but also for the pointer model, which describes the activities of the mixture components in time. The pointer model is represented by a table of transition probabilities that stochastically control the switching between the active components in dependence on the last active one. This feature brings the mixture model closer to real multi‐modal systems. It can also serve for a prediction of the future behavior of the modeled system. Copyright © 2011 John Wiley & Sons, Ltd.
Layer‐by‐Layer Growth of Multicomponent Colloidal Crystals Over Large Areas
Authors: Singh Gurvinder , Pillai Saju , Arpanaei Ayyoob , Kingshott Peter 
Published: May 2011

AbstractSelf‐assembly of different sized colloidal particles into multicomponent crystals results in novel material properties compared to the properties of the individual components alone. The formation of binary and, for the first time, ternary colloidal crystals through a simple and inexpensive confined‐area evaporation‐induced layer‐by‐layer (LBL) assembly method is reported. The proposed method produces high quality multicomponent colloidal crystal films over a broad range of particle size‐ratios and large surface areas (cm2) from silica/polystyrene colloidal suspensions of low concentration. By adjusting the size‐ratio and concentration of the colloidal particles, complex crystals of tunable stoichiometries are fabricated and their structural characteristics are further confirmed with reported crystal analogues. In addition, complex structures form as a result of the interplay of the template layer effect, the surface forces exerted by the meniscus of the drying liquid, the space filling principle, and entropic forces. Thus, this LBL approach is a versatile way to grow colloidal crystals with binary, ternary, or more complex structures.
Cyclometalated N‐Heterocyclic Carbene‐Platinum Catalysts for the Enantioselective Cycloisomerization of Nitrogen‐Tethered 1,6‐Enynes

Published: May 2011

AbstractPlatinum(II) complexes which combine six‐membered N‐heterocyclic carbene‐containing metallacyclic units and monodentate chiral phosphines have been prepared. The key step of their synthesis is the intramolecular oxidative addition of N‐2‐iodobenzylimidazolylidene‐platinum(0)‐diene complexes in the presence of the chiral phosphorus ligands. The platinum(II) metallacycles have been used as well‐defined pre‐catalysts for the enantioselective cycloisomerization of nitrogen‐tethered 1,6‐enynes into 3‐azabicyclo[4.1.0]hept‐4‐enes. High enantiomeric excesses have been obtained with either Monophos or phenyl‐Binepine based catalysts (ees=82–96%), although phenyl‐Binepine outperforms Monophos in these reactions. The absolute configuration of the final 3‐azabicyclo[4.1.0.]heptenes has been established by X‐ray diffraction studies. The method has been extended then to the cycloisomerization of dienynes with enantiotopic vinyl groups. An (S)‐phenyl‐Binepine‐platinum(II) complex allows total diastereoselectivity and high enantioselectivity levels to be attained in these reactions (ees up to 95%) which represent the first enantioselective desymetrizations achieved via enyne cycloisomerizations.

Published: May 2011

AbstractWe report the synthesis of a series of α‐glucosyl derivatives of resveratrol (3,5,4′‐trihydroxystilbene) by a transglycosylation reaction catalyzed by the enzyme cyclodextrin glucanotransferase (CGTase) using starch as glucosyl donor. Several reaction parameters (temperature, solvent composition, enzyme concentration and starch/resveratrol ratio) were optimized. The yield of α‐glucosylated products reached 50% in 24 h. The structures of the derivatives were determined by a combination of amyloglucosidase‐hydrolysis tests, MS and 2D‐NMR. Three families of products were obtained: glucosylated at 3‐OH, at 4′‐OH and at both 3‐OH and 4′‐OH. The bonds between glucoses were basically α(1→4). Interestingly, the water solubilities of the α‐glucosylated derivatives were at least 65‐ and 5‐fold higher than those of resveratrol and the natural β‐glucosylated derivative (piceid), respectively. In contrast with piceid, the synthesized α‐glucosylated compounds exhibited surfactant activity, with critical micelle concentration (CMC) values in the range 0.5–3.6 mM. Although the incorporation of a glucosyl moiety caused a loss of antioxidant activity (more pronounced in the position 3‐OH compared with 4′‐OH), the fact that the glycosides need to be converted into the aglycones before they are absorbed minimizes such an effect. In contrast, the modification of physicochemical properties such as solubility and partition coefficient by glycosylation could exert a positive influence on the bioavailability of resveratrol.
Brief communication: Oxygen isotopes as a biomarker for sickle‐cell disease? Results from transgenic mice expressing human hemoglobin S genes
Authors: Reitsema Laurie J. , Crews Douglas E. 
Published: May 2011

AbstractThe origins of sickle‐cell disease (SCD) are well understood, as are its evolutionary pressures on humans and pathological presentation. However, because it has not been possible to identify SCD in archaeological contexts, its biocultural effects on past populations are unknown. Previous research investigating oxygen isotope fractionation during respiration among anemics suggests that oxygen isotopes in bone apatite may provide a biological marker for SCD in skeletal remains. This pilot study reports δ18O ratios in bone apatite of transgenic laboratory mice expressing human SCD globins and compares them to healthy control mice. The δ18O ratios of sick mice are significantly lower than those of healthy mice (−5.6‰ vs. −4.5‰; P = 0.002), and the sickest mice exhibit the lowest ratios of all (mean δ18O = −5.8‰). These preliminary results suggest that this method may be usefully applied to skeletal materials of past human populations whose diets and water sources do not differ substantially.

Secular changes in craniofacial morphology of the portuguese using geometric morphometrics
Authors: Weisensee Katherine E. , Jantz Richard L. 
Published: May 2011

AbstractThis study examines patterns of secular change in cranial morphology in the New Lisbon collection, a documented skeletal collection from Lisbon, Portugal with birth years from 1806 to 1954. This period represents a time when Lisbon was undergoing increased urbanization and population growth, as well as changes in mortality and fertility patterns. Previous studies from the U.S., Europe, and Japan have reported significant secular changes in cranial morphology over the past 200 years. In the current study, secular changes were analyzed using three‐dimensional geometric morphometrics methods. The results from this study demonstrate a significant change in cranial morphology over the roughly 150‐year period. Allometry was rejected as a causal factor of this change because there was no association found between temporal change and size. The pattern of temporal change is similar to that observed in other populations in the U.S., Europe, and Japan, including decreased facial breadth and a more inferiorly placed cranial base. This study, along with previous research, suggests a similar pattern of change occurs in genetically and geographically diverse populations experiencing modern environmental conditions. We argue that because the secular changes are focused in the cranial base, a region of the skull that experiences a relatively early growth curve, changes related to declines in childhood morbidity and mortality are likely important factors related to the observed changes.

The maternal legacy of Basques in northern navarre: New insights into the mitochondrial DNA diversity of the Franco‐Cantabrian area

Published: May 2011

AbstractAutochthonous Basques are thought to be a trace from the human population contraction that occurred during the Last Glacial Maximum, based mainly on the salient frequencies and coalescence ages registered for haplogroups V, H1, and H3 of mitochondrial DNA in current Basque populations. However, variability of the maternal lineages still remains relatively unexplored in an important fraction of the Iberian Basque community. In this study, mitochondrial DNA diversity in Navarre (North Spain) was addressed for the first time. To that end, HVS‐I and HVS‐II sequences from 110 individuals were examined to identify the most relevant lineages, including analysis of coding region SNPs for the refinement of haplogroup assignment. We found a prominent frequency of subhaplogroup J1c (11.8%) in Navarre, coinciding with previous studies on Basques. Subhaplogroup H2a5, a putative autochthonous Basque lineage, was also observed in Navarre, pointing to a common origin of current Basque geographical groups. In contrast to other Basque subpopulations, comparative analyses at Iberian and European scales revealed a relevant frequency of subhaplogroup H3 (10.9%) and a frequency peak for U5b (15.5%) in Navarre. Furthermore, we observed low frequencies for maternal lineages HV0 and H1 in Navarre relative to other northern Iberian populations. All these findings might be indicative of intense genetic drift episodes generated by population fragmentation in the area of the Franco‐Cantabrian refuge until recent times, which could have promoted genetic microdifferentiation between the different Basque subpopulations.

Juvenile hormone changes associated with diapause induction, maintenance, and termination in the beet webworm, Loxostege sticticalis (lepidoptera: pyralidae)
Authors: Jiang Xingfu , Huang Shaohong , Luo Lizhi 
Published: May 2011

AbstractAt 22°C and under a long‐day photoperiod of L:D 16:8, all the last fifth instar Loxostege sticticalis larvae undergo prepupal stage and pupate without diapause. Under a short‐day photoperiod of L:D 12:12, in contrast, they all enter diapause with approximately 36 days diapause maintenance and then terminate diapause spontaneously, although only 44% of the larvae terminated diapause successfully. Changes in hemolymph juvenile hormone (JH I) titers of diapause‐destined larvae across diapause induction, maintenance and termination were examined using HPLC, and were compared with those of non‐diapause‐destined larvae from the fifth instar through pupation. JH I titer of the earliest fifth instar diapause‐destined larvae remained at a high level with a peak of 220.4 ng/ml, though it decreased continuously to a minimum of 69.0 ng/ml on day 5 in the fifth instar when the larvae stopped feeding to enter diapause. During the diapause maintenance, JH I titer of the mature larvae increased significantly and maintained a high level until day 31 in prepupae. JH I titer declined and fluctuated at low level from 5 days before pupation. In contrast, JH I titer of both the fifth instar non‐diapause‐destined larvae and prepupae remained and fluctuated at low level consistently, as well as decreased before pupation. These results indicate that diapause induction and maintenance in this species might be a consequence of high JH, whereas diapause termination can be attributed to low JH titer, which was in agreement with the hormonal regulation observed in many other larval‐diapausing insects. © 2011 Wiley Periodicals, Inc.

Published: May 2011

AbstractBackground: Trans‐radial approach (TRA) reduces vascular access‐site complications but has some technical limitations. Usually, TRA procedures are performed using 5 Fr or 6 Fr sheaths, whereas complex interventions requiring larger sheaths are approached by trans‐femoral access. Methods: During 4 years, at two Institutions with high TRA use, we have attempted to perform selected complex coronary or peripheral interventions by TRA using sheaths larger than 6 Fr. Clinical and procedural data were prospectively collected. Attempt to place a 7 Fr or 8 Fr sheath (according to the planned strategy of the procedure) was performed after 5–6 Fr sheath insertion, administration of intra‐arterial nitrates and radial artery angiography. Late (>3 months) patency of the radial artery was checked (by angiography in the case of repeated procedures or by palpation + reverse Allen test). Results: We collected 60 patients in which TRA large sheath insertion was attempted. The large sheath (87% 7 Fr, 13% 8 Fr) was successfully placed in all cases. Most of the procedures were complex coronary interventions (bifurcated or highly thrombotic or calcific chronic total occlusive lesions), whereas 8.3% were carotid interventions. Procedural success rate was 98.3% (1 failure to reopen a chronic total occlusion). No access‐site related complication occurred. In 57 (95%) patients, late radial artery patency was assessed and showed patency in 90% of the cases, the remaining patients having asymptomatic collateralized occlusion. Conclusions: In selected patients, complex percutaneous interventions requiring 7–8 Fr sheaths can be successfully performed by RA approach without access‐site clinical consequences. © 2011 Wiley Periodicals, Inc.
Perioperative rupture of the LIMA graft leading to cardiogenic shock, emergency angiography, and stenting with a polytetrafluoroethylene‐covered stent
Authors: Yeow Wen‐Loong , Edwards Mark , Yong Gerald 
Published: May 2011

AbstractA 58‐year‐old man underwent an elective coronary bypass graft for severe four‐vessel stenosis. Cardiogenic shock developed just after coronary bypass grafting with a left internal mammary artery (LIMA) to left anterior descending (LAD) artery and superficial venous graft to 1st and 2nd obtuse marginal (OM1/OM2) arteries the posterior descending artery (PDA) was too small to graft. Despite significant inotropes and an intra‐aortic balloon pump, the patient deteriorated in intensive care unit with cardiogenic shock and ventricular arrhythmia. Urgent coronary angiography revealed a rupture or torn LIMA graft with extravasation of contrast into the left pleural cavity. There was no distal LIMA to LAD flow probably due to graft thrombosis. Revascularisation was performed on the severe ostial native LAD stenosis with a drug eluting stent. The rupture graft was then stented with a polytetrafluoroethylene‐covered stent, which stopped the bleeding, and latter, led to total graft thrombosis. The patient improved significantly and supportive inotropes could be weaned down. At 11 month follow‐up, the patient had mild left ventricular dysfunction, widely patent ostial LAD stent and thrombosed LIMA graft. © 2011 Wiley Periodicals, Inc.
