Optimal Liquidity Provision Through a Demand Deposit Scheme: The Jacklin Critique Revisited
Authors: Zimper Alexander 
Published: March 2012

AbstractWe derive conditions such that optimal liquidity provisions through a demand deposit scheme can be sustainably implemented in a subgame perfect Nash equilibrium under the assumption that renegade investors have free access to ex post asset markets. As our qualitative main finding we demonstrate that such sustainability is more likely for ‘poor’ than for ‘rich’ scheme participants in terms of future income. By establishing sustainability for low future income populations, our formal analysis therefore offers an important qualification of Jacklin’s (1987) influential claim that an optimal demand deposit scheme is not sustainable whenever there exists the possibility of an ex post asset market.

AbstractBackground  Despite the chronicity of psoriasis, most systematic reviews focus on short‐term treatment.Methods  The systematic search strategy and results from the German Psoriasis Guidelines were adapted. To update the data a literature search in Medline, Embase and the Cochrane Library was conducted. The proportion of participants achieving ≥75% decrease in Psoriasis Area and Severity Index (PASI) as well as Dermatology Life Quality Index (DLQI) reduction at different time points were assessed. Trials were summarized with respect to time periods and study designs. Suitable trials were included in a meta‐analysis. Particular attention was paid to statistical approaches of handling dropouts.Results  A total of 33 articles including 27 trials totaling 6575 patients with active treatment were included in the systematic review. Seven randomized controlled trials were eligible for the meta‐analysis. Over a 24 week treatment period infliximab [risk difference (RD) 78%, 95% confidence interval (CI) 72–83%] and ustekinumab 90 mg every 12 weeks (RD 77%, 95% CI 71–83%) were the most efficacious treatments. Adalimumab (RD: 60%, 95% CI 45–74%) showed results within the range of different etanercept dosages (etanercept 50 mg once weekly: RD 62%, 95% CI, 52–72%), (etanercept 25 mg twice weekly: RD 45%, 95% CI 34–56%), (etanercept 50 mg twice weekly: RD 56%, 95% CI 49–62%) and (etanercept 50 mg twice weekly until week 12, then 25 mg twice weekly: RD 50%, 95% CI 42–57%). After 24 weeks a decrease in efficacy for inflximab, adalimumab and etanercept was observed.Conclusions  More sufficient data is required to draw reliable conclusions in extended long‐term treatment and head‐to‐head comparisons are necessary.

AbstractBackground  Early stage mycosis fungoides (MF) is difficult to be clinically differentiated from chronic dermatitis (CD) in a high proportion of patients. Dermoscopy is a rapid, cheep, non‐invasive and widely used method for the evaluation of skin tumours and, recently, of inflammatory skin diseases, as well.Objective  To describe the dermoscopic pattern of early stage MF and compare it with the dermoscopic features observed in CD.Methods  This was a retrospective study. Dermoscopic images of lesions that were clinically equivocal between MF and CD were evaluated for the presence of predefined morphologic criteria. Diagnosis had been histopathologically and immunohistochemically confirmed in all cases. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated for predefined dermoscopic criteria in relation to the diagnosis of mycosis fungoides.Results  A total of 67 dermoscopic images were selected for dermoscopic evaluation. Mycosis fungoides lesions exhibited a characteristic dermoscopic pattern consisting of fine short linear vessels (sensitivity 93.7%, specificity 97.1%) and orange‐yellowish patchy areas (sensitivity 90.6%, specificity 99.7%). A characteristic vascular structure resembling spermatozoa was also found to be highly specific for the diagnosis of mycosis fungoides. CD was typified by a different dermoscopic pattern, usually consisting of dotted vessels.Conclusions  These observations provide a first indication that early stage MF exhibits a characteristic dermoscopic pattern which is different from CD. Prospective studies with long term follow‐up are needed to determine the value of these dermoscopic criteria in the differentiation between the two entities in the daily routine.

Published: March 2012

AbstractSuccessful wolverine (Gulo gulo) reproduction, and thereby population viability especially in multiple‐use landscapes, is likely to be enhanced by availability of suitable den sites. We investigated which topographic features were selected for reproductive den sites by female wolverines in southernNorway (2000–2006) at three spatial scales (landscape, home‐range and site‐specific scales). At the site‐specific scale, den sites were associated with steep, rugged terrain with bare rock. At the home‐range and landscape scales, den sites were placed in rugged terrain at 1100 m a.s.l. and away from infrastructure (private roads and public roads). These features provide snowdrifts into which wolverines can excavate dry, safe cavities. Den sites were also placed away from infrastructure, indicating that den‐site distribution, and possibly successful reproduction, may be partly influenced by human activities. Recurrent use of specific topographic features may provide valuable information for guiding geographically differentiated management and monitoring efforts, and augmenting recovery of endangered wolverine populations.
Ethylene in vegetative development: a tale with a riddle
Authors: Vandenbussche Filip , Vaseva Irina , Vissenberg Kris , Van Der Straeten Dominique 
Published: March 2012

SummaryThe vegetative development of plants is strongly dependent on the action of phytohormones. For over a century, the effects of ethylene on plants have been studied, illustrating the profound impact of this gaseous hormone on plant growth, development and stress responses. Ethylene signaling is under tight self‐control at various levels. Feedback regulation occurs on both biosynthesis and signaling. For its role in developmental processes, ethylene has a close and reciprocal relation with auxin, another major determinant of plant architecture. Here, we discuss, in view of novel findings mainly in the reference plant Arabidopsis, how ethylene is distributed and perceived throughout the plant at the organ, tissue and cellular levels, and reflect on how plants benefit from the complex interaction of ethylene and auxin, determining their shape. Furthermore, we elaborate on the implications of recent discoveries on the control of ethylene signaling.

Personality effects on cardiovascular reactivity: Need for closure moderates the impact of task difficulty on engagement‐related myocardial beta‐adrenergic activity
Authors: Richter Michael , Baeriswyl Eric , Roets Arne 
Published: March 2012

AbstractAn experiment assessed the joint effect of dispositional need for closure (NFC) and task difficulty on engagement‐related myocardial beta‐adrenergic activity. Participants who scored either low or high on the NFC scale performed an ambiguous categorization task with either low or high difficulty. Confirming the theory‐derived predictions, task difficulty effects on pre‐ejection period (PEP) reactivity were moderated by NFC. If difficulty was low, PEP reactivity was low and independent of the participants’ NFC level. If difficulty was high, participants with high NFC showed increased PEP reactivity compared to participants with low NFC. These results extend previous research on Wright's model of engagement‐related cardiovascular reactivity and suggest that the model may provide a useful framework for assessing the impact of personality on cardiovascular response.
Subclinical orthostatic pulse pressure confirms mothers' ratings of ADHD in preschoolers
Authors: Casavant Vanessa , Chae Christina , Sherwani Afsheen , Perlmuter Lawrence C. 
Published: March 2012

AbstractSubclinical levels of orthostatic hypotension (OH) have been linked to a variety of emotional and behavioral outcomes across the life span. These connections are not surprising, given the multitude of correlated conditions, including autonomic control, cardiovascular functioning, baroreceptor activity, and dopamine and serotonin. The current study assessed blood pressure regulation in healthy preschool children ages 3–5 (n = 61). The Conner's Parent Rating Scale Revised was used to assess indexes of attention deficit hyperactivity disorder (ADHD). With the difference between standing and supine pulse pressure as the index of orthostatic blood pressure regulation, the results indicated that efficient pulse pressure regulation was significantly correlated with lower ADHD scores. Poorer orthostatic pulse pressure regulation in response to an orthostatic challenge may be a risk for symptoms of ADHD.
Global care chains: a state‐of‐the‐art review and future directions in care transnationalization research
Authors: YEATES NICOLA 
Published: March 2012

AbstractThis article provides a state‐of‐the‐art review and sympathetic critique of global care chain (GCC) analysis, focusing on its contributions to a sustained research agenda on care transnationalization. GCC analysis has opened up theoretical perspectives and discursive spaces for the sophisticated understandings of globalization processes. Rooted in global network methodology and cognizant of the grounded, textured and embodied nature of care transnationalization, GCC analysis has significantly contributed to better understandings of the socio‐spatial dimensions of diverse forms of care provision worldwide and the identification of transnational political and policy responses. This research agenda is far from exhausted and future research could productively address the following critiques and the conceptual and theoretical issues to which they give rise: first, that GCC research may reinforce care work as women's work; second, that it privileges some aspects of care transnationalization over others; and, third, that GCC analysis renaturalizes the nation‐state. The discussion outlines the implications of these issues for future directions in care transnationalization research.
Global care, local configurations – challenges to conceptualizations of care
Authors: RAGHURAM PARVATI 
Published: March 2012

AbstractMigration, along with the implied geographies of the ethics of care literature and policy initiatives vis‐à‐vis care have increasingly led to the adoption of the ‘global’ as the most appropriate level for analysing care. Much of the empirical work underpinning analyses of care, however, was done at particular sites and had specific emphases that are now being adopted in the analysis of care globally. In this article, I suggest the need for empirical research from other parts of the world to inform, build on and challenge the existing theorizations of transnational care. Using examples from India, I highlight some ways in which (a) recognizing the varied genealogies of care in different places, (b) bringing together the literature on care diamonds with that on care chains, and (c) recognizing the diversity of family forms and the increasing transnationalization of markets, the state and civil society may enrich existing care chain analysis. I thus suggest that we need to explore what differences in the infrastructural architecture of care means for how we theorize care in the context of migration. I outline some elements of a new research agenda, not only for research on India but also for recognizing the importance of heterogeneous care arrangements in a globalizing world of care.
The dual roles of transnational daughters and transnational wives: monetary intentions, expectations and dilemmas
Authors: THAI HUNG CAM 
Published: March 2012

AbstractUtilizing in‐depth interview data from a larger study of Vietnamese transnational marriages, in this article I focus on how Vietnamese transnationally married daughters talk about their plans to provide financially for their elderly parents in the homeland. While single adult daughters from Vietnam are equally likely as single adult sons to provide financially for their parents, married daughters are much less likely to do so than married sons. Yet, paradoxically, a transnational marriage with the prospect of eventual international migration positions daughters as important potential financial providers, not because they are daughters, but because they are transnational daughters. When they eventually migrate, however, they will not only become transnational migrant daughters but also transnational migrant wives. These transnational daughters must, therefore, negotiate their intentions to provide monetary support, expected from them because they will become migrants, against their husbands' objections to the fact that their wives are daughters, and therefore, not responsible for monetary support to ageing parents according to traditional Vietnamese kinship practices.
Transnational marriages as a strategy of care exchange: veteran soldiers and their mainland Chinese spouses in Taiwan
Authors: LU MELODY CHIA‐WEN 
Published: March 2012

AbstractIn this article, I discuss how Taiwanese veterans and their mainland Chinese wives use transnational marriages as a strategy to obtain care and security in old age. The state's population, welfare and immigration policies shape the veterans' care needs and rights. Middle‐aged mainland Chinese women choose to migrate to provide security for themselves and better educational and economic opportunities for their children. I use Stafford's concept of ‘cycles of yang’ to explain why, despite state provision of care, family members prefer reciprocity of care and why they choose transnational marriage in preference to other forms of family formation. This framework blurs the distinction between caregivers and care receivers, and conceptualizes differential care needs as part of the life course. I use the concept of a care diamond to analyse how state policies, communal care and market forces together shape care relationships in transnational families and patterns of transnational mobility.
The reproductive labour of migrant workers

Published: March 2012

AbstractIn this article, I revisit my formulation of the ‘international division of reproductive labour’, also known as the ‘care chain’, and address its impacts on the study of migrant care workers. I also address future directions in the study of migrant care workers, calling attention to the contributions made in this special issue, specifically the need to focus on elderly care, different organizational arrangements of care, and the geopolitics of care.
Teachers’ recognition of children with ADHD: role of subtype and gender
Authors: Moldavsky Maria , Groenewald Carla , Owen Victoria , Sayal Kapil 
Published: March 2012

BackgroundThis study investigates the ability of primary school teachers to recognise Attention Deficit/Hyperactivity Disorder (ADHD), and the impact of subtype and child gender on recognition and proposed management.MethodPrimary school teachers read one of four types of vignette describing the behaviour of a 9‐year‐old child: either a boy or a girl with inattentive or combined subtype of ADHD. Teachers were asked about their conceptualisation of the child's difficulties and their thoughts about need for specialist referral and other interventions.ResultsOf 496 teachers, 99% identified the presence of a problem. Subtype (combined) of ADHD influenced teachers’ recognition of ADHD and agreement that medication might be helpful. Only 13% of teachers thought that medication might be helpful.ConclusionsResults suggest a need for better teacher awareness about inattentive subtype of ADHD.

BackgroundThis study focused on the behavioral functioning and treatment outcomes of preschool‐aged children who attended a specialized, family focused psychiatric partial hospitalization program.MethodStudy data were collected between 2002 and 2007. Maternal reports of child behavioral functioning were obtained at program admission and discharge. Maternal parenting stress and psychiatric impairment were assessed at admission.ResultsChildren's symptom severity decreased from admission to discharge, particularly with respect to externalizing symptoms. Both child age and maternal functioning emerged as predictors of treatment outcome.ConclusionsSpecialized partial hospitalization may be an effective approach to treatment for preschool children with severe psychopathology.
MDMA and 5‐HT neurotoxicity: the empirical evidence for its adverse effects in humans – no need for translation
Authors: Parrott Andrew C 
Published: March 2012

In this issue of the BJP, Green et al. suggest that animal data could not be used to predict the adverse effects of 3,4‐methylenedioxymethamphetamine (MDMA) in humans and that MDMA did not produce 5‐HT neurotoxicity in the human brain. This proposal was, however, not accompanied by a review of the empirical evidence in humans. The neuroimaging data on 5‐HT markers in abstinent recreational ecstasy/MDMA users are extensive and broadly consistent. Reduced levels of the 5‐HT transporter (SERT) have been found by research groups worldwide using a variety of assessment measures. These SERT reductions occur across the higher brain regions and remain after controlling for potential confounds. There are also extensive empirical data for impairments in memory and higher cognition, with the neurocognitive deficits correlating with the extent of SERT loss. Hence, MDMA is clearly damaging to humans, with extensive empirical data for both structural and functional deficits.LINKED ARTICLES This article is a commentary on Green et al., pp. 1523–1536 of this issue.

Published: March 2012

BACKGROUND AND PURPOSE The sigma‐1 (σ1) receptor is a ligand‐regulated molecular chaperone that has been involved in pain, but there is limited understanding of the actions associated with its pharmacological modulation. Indeed, the selectivity and pharmacological properties of σ1 receptor ligands used as pharmacological tools are unclear and the demonstration that σ1 receptor antagonists have efficacy in reversing central sensitization‐related pain sensitivity is still missing.EXPERIMENTAL APPROACH The pharmacological properties of a novel σ1 receptor antagonist (S1RA) were first characterized. S1RA was then used to investigate the effect of pharmacological antagonism of σ1 receptors on in vivo nociception in sensitizing conditions and on in vitro spinal cord sensitization in mice. Drug levels and autoradiographic, ex vivo binding for σ1 receptor occupancy were measured to substantiate behavioural data.KEY RESULTS Formalin‐induced nociception (both phases), capsaicin‐induced mechanical hypersensitivity and sciatic nerve injury‐induced mechanical and thermal hypersensitivity were dose‐dependently inhibited by systemic administration of S1RA. Occupancy of σ1 receptors in the CNS was significantly correlated with the antinociceptive effects. No pharmacodynamic tolerance to the antiallodynic and antihyperalgesic effect developed following repeated administration of S1RA to nerve‐injured mice. As a mechanistic correlate, electrophysiological recordings demonstrated that pharmacological antagonism of σ1 receptors attenuated the wind‐up responses in spinal cords sensitized by repetitive nociceptive stimulation.CONCLUSIONS AND IMPLICATIONS These findings contribute to evidence identifying the σ1 receptor as a modulator of activity‐induced spinal sensitization and pain hypersensitivity, and suggest σ1 receptor antagonists as potential novel treatments for neuropathic pain.
Improved Cumulative Survival in Fistulas Requiring Surgical Interventions to Promote Fistula Maturation Compared with Endovascular Interventions
Authors: Lee Timmy , Tindni Arshdeep , Roy‐Chaudhury Prabir 
Published: March 2012

AbstractDue to high nonmaturation rates, arteriovenous fistulas (AVF) frequently require intervention(s) to promote maturation. Endovascular or surgical interventions are often undertaken to salvage nonmaturing AVFs. The objective of this study was to compare the impact of surgical versus endovascular interventions to promote AVF maturation on cumulative AVF survival.We evaluated 89 patients with new AVF placement from a Veterans Affairs population over a 5‐year period. Of these, 46 (52%) required intervention(s) to achieve successful maturation for dialysis: 31 patients had surgical revisions and 15 patients had endovascular repairs. We compared cumulative survival between AVFs requiring no intervention, surgical revision, and endovascular intervention to promote AVF maturation.Cumulative survival was longer in AVFs receiving surgical intervention compared with angioplasty to promote AVF maturation (p = 0.05). One‐year cumulative survival was 86% vs. 83% vs. 40% for no intervention vs. surgery vs. angioplasty, respectively.In AVFs that required interventions to promote maturation, AVFs with surgical intervention had longer cumulative survival compared with those AVFs with endovascular intervention. AVFs with surgical intervention to promote maturation had similar 1‐year cumulative survival to those AVFs that did not require intervention to promote maturation.
