Securitization of Longevity Risk Using Percentile Tranching
Authors: Kim Changki , Choi Yangho 
Published: September 2010

AbstractSecuritizations that transfer risk to the financial markets are a potential solution to longevity risk in the annuity business. The classical Lee–Carter model is applied to generate the future stochastic survival distribution. A method to design inverse survivor bonds using percentile tranches and to calculate the security prices is presented. The percentile tranche method is a simple and practical way for the issuer to design and price the security. This method can serve to identify the risk–yield relationship, which can provide investors with clear insight regarding the appropriate choice of tranches.

ABSTRACTSupply networks are composed of large numbers of firms from multiple interrelated industries. Such networks are subject to shifting strategies and objectives within a dynamic environment. In recent years, when faced with a dynamic environment, several disciplines have adopted the Complex Adaptive System (CAS) perspective to gain insights into important issues within their domains of study. Research investigations in the field of supply networks have also begun examining the merits of complexity theory and the CAS perspective. In this article, we bring the applicability of complexity theory and CAS into sharper focus, highlighting its potential for integrating existing supply chain management (SCM) research into a structured body of knowledge while also providing a framework for generating, validating, and refining new theories relevant to real‐world supply networks. We suggest several potential research questions to emphasize how a CAS perspective can help in enriching the SCM discipline. We propose that the SCM research community adopt such a dynamic and systems‐level orientation that brings to the fore the adaptivity of firms and the complexity of their interrelations that are often inherent in supply networks.
Vertical Integration with Price‐Setting Competitive Newsvendors*

Published: September 2010

ABSTRACTThis article addresses the problem of distribution channel design under demand uncertainty. We consider two manufacturers, each producing a substitutable product and selling it through either a decentralized or an integrated retail store, which is modeled as a price‐setting newsvendor. A multiplicative demand function incorporating a random shock term is assumed. Of primary interest is how demand uncertainty and production cost affect the equilibrium distribution channel structure. Results indicate the following: On the one hand, if the random shock term is uniformly distributed on [0, x], then the equilibrium design does not depend on the variance of the shock. On the other hand, if the random shock term is uniformly distributed on [1 −r, 1 +r], then the equilibrium design does depend on the variance of the shock. In particular, an increase in r favors the integrated structure where both channels are integrated and hurts the decentralized configuration where both channels are decentralized. Additionally, we explain the qualitative similarities and differences between the structural properties of the equilibrium distribution channel structure when demand is, and is not, uncertain. We also establish that production cost always favors the decentralized structure, while it hurts the integrated one. One important managerial implication of our study is that, by reducing the number of decisions made in supply chains, the impact of demand uncertainty can be controlled to a certain extent.

Oliynyk I, Varelogianni G, Roomans GM, Johannesson M. Effect of duramycin on chloride transport and intracellular calcium concentration in cystic fibrosis and non‐cystic fibrosis epithelia. APMIS 2010; 118: 982–90.The lantibiotic duramycin (Moli1901, Lancovutide) has been suggested as a drug of choice in the treatment for cystic fibrosis (CF). It has been proposed that duramycin may stimulate chloride secretion through Ca2+‐activated Cl−channels (CaCC). We investigated whether duramycin exhibited any effect on Cl−efflux and intracellular Ca2+concentration ([Ca2+]i) in CF and non‐CF epithelial cells. Duramycin did stimulate Cl−efflux from CF bronchial epithelial cells (CFBE) in a narrow concentration range (around 1 μM). However, 100 and 250 μM of duramycin inhibited Cl−efflux from CFBE cells. An inhibitor of the CF transmembrane conductance regulator (CFTRinh‐172) and a blocker of the capacitative Ca2+entry, gadolinium chloride, inhibited the duramycin‐induced Cl−efflux. No effect on Cl−efflux was observed in non‐CF human bronchial epithelial cells (16HBE), human airway submucosal gland cell line, human pancreatic epithelial cells, CF airway submucosal gland epithelial cells, and CF pancreatic cells. The [Ca2+]iwas increased by 3 μM duramycin in 16HBE cells, but decreased after 1, and 3 μM of duramycin in CFBE cells. The results suggest that the mechanism responsible for the stimulation of Cl−efflux by duramycin is mainly related to unspecific changes of the cell membrane or its components rather than to effects on CaCC.

APMIS 2010; 118: 991–3.We have compared three ELISA techniques and one chemiluminescence immunoassay technique for determining cytomegalovirus (CMV) immunoglobulin G (IgG) avidity in serum samples from patients with recent and past CMV infections. Sensitivity varied from 84.6% to 100%; and specificity from 78.6% to 100%. IgG avidity assays appear to be adequate additional tools for characterizing CMV infections.

Shellis RP, Barbour ME, Jones SB, Addy M. Effects of pH and acid concentration on erosive dissolution of enamel, dentine, and compressed hydroxyapatite. Eur J Oral Sci 2010; 118: 475–482. © 2010 Eur J Oral Sci The aims of this study were to determine the effects of pH and acid concentration on the dissolution of enamel, dentine, and compressed hydroxyapatite (HA) in citric acid solutions (15.6 and 52.1 mmol l−1; pH 2.45, 3.2, and 3.9), using a pH‐stat system. After an initial adjustment period, the dissolution rates of enamel and HA were constant, while that of dentine decreased with time. The dissolution rate increased as the pH decreased, and this was most marked for enamel. To compare substrates, the rate of mineral dissolution was normalized to the area occupied by mineral at the specimen surface. For a given acid concentration, the normalized dissolution rate of HA was always less than that for either dentine or enamel. The dissolution rate for dentine mineral was similar to that for enamel at pH 2.45 and greater at pH 3.2 and pH 3.9. The concentration of acid significantly affected the enamel dissolution rate at pH 2.45 and pH 3.2, but not at pH 3.9, and did not significantly affect the dissolution rates of dentine or HA at any pH. The variation in response of the dissolution rate to acid concentration/buffer capacity with respect to pH and tissue type might complicate attempts to predict erosive potential from solution composition.

Zhou Z-H, Yuan G-Z, Yao J-J, Li C, Cheng Z-H. An event-related potential investigation of deficient inhibitory control in individuals with pathological Internet use.Objective:The purpose of this study was to investigate deficient inhibitory control in individuals with pathological Internet use (PIU) using a visual go/no-go task by event-related potentials (ERPs).Methods:Subjects were 26 individuals with PIU and 26 controls. Barratt Impulsiveness Scale-11 (BIS-11) was used for measures of impulsivity. A go/no-go task involved eight different two-digit numerical stimuli. The response window was 1000 ms and the inter-trial-interval (ITI) was 1500 ms. Electroencephalography (EEG) was recorded when participants performed the task. Brain electrical source analysis (BESA) 5.2.0 was used to perform data analysis and the no-go N2 amplitude was analysed for investigation of inhibitory control.Results:BIS-11 total scores, attentional key and motor key scores in PIU group were higher than that of the control group. In the go/no-go task, false alarm rate of PIU group was higher, and hit rate was lower than that of the control group. A repeated measure ANOVA revealed a significant group, frontal electrode sites and group × frontal electrode sites main effect for N2 amplitudes of no-go conditions (for group: F = 3953, df = 1, p = 0.000; for frontal electrode sites: F = 541, df = 9, p = 0.000; for group × frontal electrode sites: F = 306, df = 9, p = 0.000), and a significant group, central electrode sites and group × central electrode sites main effect for N2 amplitudes of no-go conditions (for group: F = 9074, df = 1, p = 0.000; for central electrode sites: F = 163, df = 2, p = 0.000; for group × central electrode sites: F = 73, df = 2, p = 0.000). N2 amplitudes of no-go conditions were lower than those at control group.Conclusions:Individuals with PIU were more impulsive than controls and shared neuropsychological and ERPs characteristics of compulsive-impulsive spectrum disorder, which supports that PIU is an impulse disorder or at least related to impulse control disorder.

Loughland CM, Allen J, Gianacas L, Schofield PW, Lewin TJ, Hunter M, Carr VJ. Brief neuropsychological profiles in psychosis: a pilot study using the Audio Recorded Cognitive Screen (ARCS).Objective:This pilot study examines the utility of a novel, standardised brief neuropsychological assessment tool (the ARCS, Audio Recorded Cognitive Screen) in a different clinical setting to that in which it was initially developed. We hypothesised that the ARCS would be feasible to administer to individuals with a psychotic illness and that it would detect cognitive deficits similar to those identified by an established instrument (the RBANS, Repeatable Battery for the Assessment of Neuropsychological Status).Methods:Twenty-five people with psychosis (mean age = 43.72, SD = 9.78) and 25 age- and gender-matched controls were recruited from the Newcastle community (NSW, Australia). The ARCS and RBANS were completed about 1 week apart in a counterbalanced order.Results:The ARCS was well received, performed satisfactorily and both the ARCS and RBANS were sensitive to deficits typically associated with psychosis (e.g. memory and attention). After controlling for memory deficits, the largest disparity between the psychosis and control groups was on the ARCS fluency domain [p< 0.001, partial Eta-squared (ηp2) = 0.21].Conclusion:The ARCS uses audio administration (approximately 34 min) to reduce clinician time (to 3–5 min for scoring) and appears to be a useful brief assessment tool for examining the cognitive deficits associated with psychosis. However, the potential clinical utility of the ARCS needs to be investigated further in larger samples drawn from a wider variety of specialist and non-specialist settings.

Authors: Gattuso Suzy , Saw Celia 
Published: September 2010

Book reviews in this article:Objective: To assess expectations about ageing of rural‐ and urban‐reared students preparing for careers in health and human services.Method: A survey of 136 students at three rural campuses was conducted using the Reactions to Ageing Questionnaire. Students were enrolled in first‐ and second‐year occupational therapy, nursing and welfare. Intimate contact with older people, defined as the number of people aged 65 and over counted as family or friends, was treated as a moderator variable.Results: There was a significant difference in attitude depending on the background of students, with rural students being more negative in attitude. Neither course of study nor intimate contact was associated with attitude score.Conclusions: Rural background may be an important factor in attitudes towards ageing and attitudes may be relatively independent of intimate contact with older people.
Subjective Quality of Life, Perceived Control and Dispositional Optimism Among Older People
Authors: Maher Elise , Cummins Robert A. 
Published: September 2010

Book reviews in this article:Objectives: To examine whether the subjective quality of life (QOL) of elderly people is held under homeostatic control, and to investigate the role of perceived control and dispositional optimism in the maintenance of subjective QOL.Method: 100 older people (M=75.6 years) and a control group of 107 younger people (M=20.1 years) completed a self‐report survey.Results: Both groups had a level of subjective QOL within the normal range. The older group reported higher levels of secondary control and optimism, but similar levels of primary control, as the younger group. Primary control and optimism predicted subjective QOL for both groups. Secondary control was a significant predictor for the younger group, however it was only marginally significant for the older group. Optimism accounted for the most subjective QOL variance for both groups.Conclusions: The finding that the subjective QOL of the older group lay within the normative range supports the proposal that their subjective QOL is being successfully maintained under homeostatic control. However, they appear to have an increased reliance on secondary control. The fact that dispositional optimism captures the predictive variance of perceived control, is an important finding adding to the understanding of subjective QOL maintenance.

Book reviews in this article:Objective: The South Australian Government funded the Rural Online Research Project to investigate Internet use by older people in rural South Australia.Method: Information was gathered from this population via questionnaires in relation to their use of computers and the Internet and focus groups were held to supplement this data.Results: Findings indicated that of the 16% of older rural residents who used the Internet the most common uses were email, browsing, games and accessing travel or entertainment information. Over half of those not using the Internet indicated that they would like to learn and the majority indicated that major barriers to use were lack of opportunity and cost involved.Conclusion: Opportunity, cost and a supportive learning environment are key factors in encouraging Internet use by older people in rural areas.
Robot-Assisted Laparoscopic Prostatectomy in Patients with Preexisting Three-Piece Inflatable Penile Prosthesis
Authors: Erdeljan Petar , Brock Gerald , Pautler Stephen E. 
Published: September 2010

ABSTRACT

Introduction
Robotic-assisted laparoscopic radical prostatectomy (RARP) is becoming the preferred surgical treatment option for management of organ-confined prostate cancer. Although not a contraindication, previous pelvic surgery can make RARP challenging. Presence of a three-piece inflatable penile prosthesis, with a perivesical pelvic reservoir, has the potential to induce steric hindrance making RARP difficult.

Aim
The main purpose of this publication is to report our experience with RARP in patients with previously inserted three-piece inflatable penile prostheses.

Methods
Two patients with previously inserted AMS 700 penile prosthesis and with organ-confined, biopsy proven adenocarcinoma of the prostate underwent RARP. We describe intraoperative findings, surgical technique, oncologic and functional outcomes.

Results
Both patients underwent safe and successful RARP with out any complications. Surgical margins were not affected with pelvic reservoir-sparing technique. In both patients, the penile prosthesis remained functional postoperatively.

Conclusions
RARP can be safely performed in patients with previously inserted three-piece inflatable penile prosthesis. Nontraumatic handling of the pelvic reservoir is mandatory to preserve prosthesis’ integrity.

AbstractAim:  The aim of the present study was to compare the efficacy of 200 mg versus 400 mg daily of pyridoxine in preventing or delaying the onset of palmar‐plantar erythrodysesthesia (PPE) in capecitabine‐treated patients.Methods:  Patients with histologically confirmed breast cancer or colorectal cancer receiving single agent capecitabine started at 2000 to 2500 mg/m2 daily from day 1 to 14 every 3 weeks were randomly assigned to receive 200 mg or 400 mg daily of pyridoxine for PPE prophylaxis. The primary endpoint was the reduction of incidence of grade 2 or greater PPE. Secondary endpoints were reduction of severe PPE and prolongation of time to development of grade 2 or greater PPE.Results:  There were 56 patients in this study. The baseline characteristics were generally similar in both groups. The high dose arm had less PPE than the low dose arm (11 of 28 or 39% vs 20 of 28 or 71%, relative risk = 0.26 [0.08, 0.79], P = 0.031). Grade III PPE developed in 3 of 28 (10.7%) versus none in patients receiving 200 mg versus 400 mg pyridoxine, respectively (relative risk 2.12 [1.594, 2.819], P = 0.24). High dose pyridoxine had a longer time to development of grade 2 or greater PPE compared to the low dose arm, 87 days versus 62 days. The 400 mg pyridoxine group had, however, a worsened tumor response and tended to have greater tumor treatment failure and shorter time to treatment failure.Conclusion:  With the limitation of sample size in this study, there was a trend to improve PPE incidence and time to event with a higher dose of pyridoxine. Further validation of these results in a larger population is warranted.
Effect of seed coating on plant growth and soil conditions: A preliminary study for restoration of degraded rangeland in the Qinghai–Tibetan Plateau, China

AbstractRangeland degradation is a significant problem in the Qinghai–Tibetan Plateau, China. Restoration of the degraded rangelands through reseeding is being undermined by poor seedling growth under adverse soil moisture and nutrition conditions. Accordingly, seeds of Italian ryegrass (Lolium multiflorum) and Chinese milk vetch (Astragalus sinicus) were coated with a mixture of hygroscopic and plant‐derived polysaccharide gums and alga powder (Phaeocystis sp. necolon‐1), and inoculated with spores of microorganisms (Aspergillus sp. and Streptomyces sp.), serving as coating mixture decomposers, in order to improve rhizosphere moisture and nutrition. In a growth chamber simulating spring climate on the Plateau, seedling emergence of the coated seeds was 60–80 and 48–82%, respectively, for the two plant species in comparison to 38 and 24% for the uncoated seeds, which was due to moisture being supplied by the coat. In the outdoor pots with soil texture and moisture conditions similar to those of the degraded rangelands on the Plateau, dry weight of the plants from the coated seeds was 109–184 and 118–156 mg plant−1 for the respective plant species, while that of the plants from uncoated seeds was 18–20 and 10–11 mg plant−1. The number of Rhizobium sp. nodules on Chinese milk vetch plants from the coated seeds was 21–25 plant−1 while 0–2 in plants from uncoated seeds. Enhancement of plant growth was caused by increased activity of soil microbes. Plant growth on the soil after sampling plants from the coated seeds was also enhanced, indicating sustainability of improvement of soil conditions. Thus seed coating with hygroscopic nutrient‐source materials and inoculation with microorganism spores as slow decomposers of the coating materials is a promising method for restoring degraded rangelands.

AbstractUtilization by cattle of a pasture with a heterogeneous environment was assessed from early May to late October 2005 based on the behavior of two cows fitted with GPS units and bite counter collars as members of a group of 10 animals. The pasture (7.6 ha; established in 1967 with five temperate species) consisted of three subunits (almost identical sizes) differing in renovation history, vegetation and terrain: Subunit 1, a relatively flat section renovated by over‐seeding a grass in 2002; Subunit 2, a sloped section (no renovation); and Subunit 3, a sloped section including woods (no renovation). Spatial distributions and the number of bites of the two collared cows were obtained at 10 min intervals during five 10 day trials in each month except July. The two cows showed similar tendencies in choosing locations and in the number of bites per day and per hour among the subunits in each month. The cows spent most of their time in Subunit 1 in May and June, but as the months went by, the time in Subunit 1 became short and was limited to daytime. In contrast, they stayed predominantly in Subunits 2 and 3 at night in the latter half of the season. Throughout the season, the number of bites taken in Subunit 1 was the greatest among all of the subunits. Our results suggested that the aged, hilly sections (Subunits 2 and 3) were mainly utilized as resting sites in the nighttime and were supplementarily grazed in the latter half of the season. To prevent early deterioration of the relatively flat, renovated section, an increase in grazing use of the aged, hilly sections will be needed.
