Income Comparison as a Determining Mechanism of Class Identification: A Quantitative and Simulation Study Using Japanese Survey Data
Authors: Maeda Yutaka , Ishida Atsushi 
Published: April 2013

AbstractThis paper questions whether personal income comparison explains the distributive gap between income and class identification by exploring the following two issues: empirical validity of income comparison as the determinant of class identification, and theoretical validity of income comparison for the distributive gap. For the first issue, we conduct a statistical analysis using data from the Social Stratification and Social Mobility surveys (1975–2005), and the Stratification and Social Psychology‐I survey (2010). We find that the criteria for choosing reference groups changed historically from residential proximity to occupational equality. In addition, income comparison with sensitive to lower‐income possessors and a distorted perception of income difference significantly affected class identification, except for the year of 1985. The simulation analysis employed to examine the second issue clarified that income comparison with the above‐mentioned features yields a less skewed distribution compared to that of class identification. The data also indicates that the empirical conditions of income are satisfied for realization of this result. Thus, we could ascertain empirical and theoretical validity of income comparison as explanation for the distributive gap between income and class identification.
Managing Capital Market and Longevity Risks in a Defined Benefit Pension Plan
Authors: Cox Samuel H. , Lin Yijia , Tian Ruilin , Yu Jifeng 
Published: April 2013

ABSTRACTThis article proposes a model for a defined benefit pension plan to minimize total funding variation while controlling expected total pension cost and funding downside risk throughout the life of a pension cohort. With this setup, we first investigate the plan's optimal contribution and asset allocation strategies, given the projection of stochastic asset returns and random mortality evolutions. To manage longevity risk, the plan can use either the ground‐up hedging strategy or the excess‐risk hedging strategy. Our numerical examples demonstrate that the plan transfers more unexpected longevity risk with the excess‐risk strategy due to its lower total hedge cost and more attractive structure.

SUMMARYBackgroundHyperphosphataemia is a known independent risk factor for cardiovascular mortality. The objective of the study was to compare the effects of two phosphate binders, sevelamer carbonate and calcium carbonate on endothelial function (EF) and inflammation in patients on peritoneal dialysis (PD) with Type 2 diabetes mellitus (T2DM).MethodsFifteen subjects with hyperphosphataemia discontinued all phosphate binders to undergo a two‐week washout and were assigned to sevelamer carbonate or calcium carbonate treatments for eight weeks. After a second two‐week washout period, subjects crossed over to either of the alternate treatments for another eight weeks. At the beginning and end of each treatment, biomarkers of EF, pro‐inflammatory cytokines, serum albumin, calcium, phosphate and lipids were measured.ResultsSevelamer carbonate significantly improved lipid profile compared with calcium carbonate. Amongst the EF and pro‐inflammatory biomarkers, sevelamer carbonate decreased serum endothelin‐1, plasminogen activator inhibitor‐1, C‐reactive protein and interleukin‐6. Both phosphate binders were effective in decreasing serum phosphate but sevelamer had a positive effect on EF.ConclusionsTreatment with sevelamer carbonate has beneficial effects compared with calcium carbonate in decreasing inflammation and improving EF in patients with T2DM on PD.
Employed and Unemployed Job Seekers and the Business Cycle
Authors: Longhi Simonetta , Taylor Mark 
Published: April 2013

AbstractThe job search literature suggests that on‐the‐job search reduces the probability of un employed people finding jobs. However, there is little evidence that employed and unemployed job seekers are similar or apply for the same jobs. We compare employed and unemployed job seekers in their individual characteristics, preferences over working hours, job‐search strategies and employment histories, and identify how differences vary over the business cycle. We find systematic differences which persist over the business cycle. Our results are consistent with a segmented labour market in which employed and unemployed job seekers are unlikely to directly compete with each other for jobs.
MIDGETconnectsCOP1‐dependent development with endoreduplication inArabidopsis thaliana
Authors: Schrader Andrea , Welter Bastian , Hulskamp Martin , Hoecker Ute , Uhrig Joachim F. 
Published: April 2013

SummaryInArabidopsis thaliana, loss ofCONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) function leads to constitutive photomorphogenesis in the dark associated with inhibition of endoreduplication in the hypocotyl, and a post‐germination growth arrest.MIDGET(MID), a component of theTOPOISOMERASE VI(TOPOVI) complex, is essential for endoreduplication and genome integrity inA. thaliana. Here we show thatMIDandCOP1 interactin vitroandin vivothrough the amino terminus ofCOP1. We further demonstrate thatMIDsupports sub‐nuclear accumulation ofCOP1. TheMIDprotein is not degraded in aCOP1‐dependent fashion in darkness, and the phenotypes of single and double mutants prove thatMIDis not a target ofCOP1 but rather a necessary factor for properCOP1 activity with respect to both, control ofCOP1‐dependent morphogenesis and regulation of endoreduplication. Our data provide evidence for a functional connection betweenCOP1 and theTOPOVIin plants linkingCOP1‐dependent development with the regulation of endoreduplication.

Published: April 2013

ABSTRACT

Nineteen linezolid-resistant
Staphylococcus epidermidis
and two
Staphylococcus aureus
isolates recovered from two medical institutions in northeast Ohio and an
S. aureus
cfr
index strain previously collected in the same facilities during the 2007 SENTRY Antimicrobial Surveillance Program were investigated for the genetic basis of oxazolidinone resistance and the location of
cfr. S. aureus
isolates were typed by pulsed-field gel electrophoresis (PFGE),
spa
typing, and multilocus sequence typing (MLST). The location of
cfr
was determined by Southern blotting and hybridization. Plasmid sequencing was performed using the 454 Life Sciences (Roche) GS-FLX DNA platform. The two
S. aureus
isolates showed unique PFGE patterns but were multilocus sequence type 5 (ST5) and
spa
type t002, whereas the
S. aureus
index strain was ST239 and t037. Southern blot and hybridization experiments showed that
cfr
was plasmid located and that the
S. epidermidis
isolates, one of the
S. aureus
isolates, and the
S. aureus
index strain shared an identical
cfr
-carrying plasmid (39.3 kb). Sequencing results confirmed these findings. A 10-kb fragment containing
cfr
showed the highest identity (99.9%) to a 9.5-kb fragment of plasmid pSCFS3 from a bovine
Staphylococcus lentus
isolate from Germany. In addition, these 39.3-kb plasmids from human
S. epidermidis
and
S. aureus
exhibited BglII restriction profiles very similar to that observed for plasmid pSCFS3. The
cfr
-carrying plasmid detected in the remaining
S. aureus
isolate (7.9 kb) was distinct and showed the highest identity to the chromosomal
cfr
integrate found in the chromosomal DNA of a
Proteus vulgaris
isolate from a pig in China.

Considering Streamflow Trend Analyses Uncertainty in Urbanizing Watersheds: A Baseflow Case Study in the Central United States
Authors: Hubbart Jason A. , Zell Chris 
Published: April 2013

Abstract
Assuming pro rata reductions in baseflow resulting from urban development may not be valid in all urbanizing watersheds. Anthropogenic offsets or compensatory contributions to baseflow (e.g., net exfiltration from sewer lines, wastewater effluents, and lawn irrigation) may mask or confound fundamental changes in hydrologic pathways. These offsets illustrate the complexities of urban flow processes and the need for improved understanding to mitigate urban development impacts. The authors used two dissimilar automated baseflow separation algorithms and Monte Carlo techniques to evaluate urban baseflow and estimation uncertainty using data from a representative urban watershed in the central United States. Three uncertainties affecting trend determinations were assessed, including algorithm structure, precipitation–runoff relationships, and baseflow algorithm parameterization. Results indicate that, despite ongoing population growth and development, annual streamflow metrics in the authors' representative watershed have not significantly increased or decreased (p &gt; 0.05) from 1967 to 2010. However, several streamflow metrics featured shallow insignificant (p &gt; 0.05) slopes in the direction hypothesized for an urbanizing (less pervious) watershed, including a downward slope for baseflow index (BFI) and increases in runoff volume coefficient. Median annual baseflow estimations differed by 29% between techniques (85.3 versus 118.9 mm yr−1). In the absence of direct tracer measurements, uncertainties associated with precipitation–runoff relationships, algorithm structure, and parameterization should be included in analyses evaluating alterations from baseline hydrologic conditions in urban watersheds. To advance application of separation algorithms for urban watersheds and support regulatory reductions in runoff volume, future work should include calibration of model parameters to available hydrogeologic and tracer data.
Turks and Caicos Islands Climate and Its Impacts
Authors: Jury Mark R. 
Published: April 2013

AbstractThe Turks and Caicos Islands (TCI) climate is described using mesoscale ocean and atmosphere datasets with a focus on thermodynamic versus kinematic controls, the influence of the nearby island of Hispaniola, and factors affecting early colonization and fluctuations of marine resources. The key findings include the following: trade winds accelerate to 7 m s−1 north of Hispaniola and enhance anticyclonic subsidence; there is a dry-south/wet-north pattern of rainfall that opposes surface temperature and salinity fields; ocean currents near TCI are northwestward but there is a counterclockwise gyre near Haiti that guided colonization; conch catch increases when trade winds strengthen and SST declines; TCI's dry climate limits groundwater resources, food production, and population density; and Caicos Island sheds a wind wake that boosts SST and local convection, as evident in Quick Scatterometer (QuikSCAT) observations and operational model products. Further studies of small island climates will benefit from an ever-increasing stream of mesoscale datasets.
Thrombus formation using endovenous lasers: an in vitro experiment
Authors: Hennings T , Hennings D , Lindsay C 
Published: April 2013

Objectives: The purpose of these experiments was to simulate thrombus formation during endovenous laser closure by measuring coagulum formation of in vitro laser exposures in porcine blood and investigate the role of procedures and equipment in thrombus formation. Methods: Continuous wave 810, 940, 980, 1310 and 1470 nm lasers and microsecond pulsed wave 1064 nm Nd:YAG (neodymium-doped yttrium aluminium garnet), 1320 nm Nd:YAG and 2100 nm THC:YAG (thulium holmium chromium-doped yttrium aluminium garnet) lasers were tested with standard fibres with diameters of 365, 550 and 600 μm as well as two prototype modified tip fibres. Results: The results show that pulsed lasers with high-peak power densities form less coagulum. Fibre specifications were found not to influence coagulum formation, and prototype modified tip fibres designed to prevent contact between the fibre tip and the vein wall did not eliminate coagulum formation. Conclusion: Microsecond-pulsed wave lasers with high-peak power densities may be a better choice to minimize soft thrombus formation during endovenous laser ablation treatments.
Development and Validation of the Sorokin Psychosocial Love Inventory for Divorced Individuals
Authors: D’Ambrosio Joseph G. , Faul Anna C. 
Published: April 2013

Objective: This study describes the development and validation of the Sorokin Psychosocial Love Inventory (SPSLI) measuring love actions toward a former spouse. Method: Classical measurement theory and confirmatory factor analysis (CFA) were utilized with an a priori theory and factor model to validate the SPSLI. Results: A 15-item scale containing five subscales (intensity, extensity, purity, adequacy, and duration) showed good fit, statistically significant factor loadings, good reliability, and validity. Multigroup CFA indicated both measurement equivalence and structural equivalence between males and females. Discussion: The SPSLI supports Sorokin’s multidimensional theory of love and provides clinicians a method to measure love actions of divorcing individuals. Implications for practice and future research are discussed.
A Fast Method to Estimate the Wall Shear Stress Waveform in Arteries
Authors: Yang Xin , Hollis Lyam , Adams Fiona , Khan Faisel , Hoskins Peter R 
Published: April 2013

Introduction Ultrasound has been applied to measure vessel diameter and blood flow velocity to compute the wall shear rate (WSR) in arteries. This paper describes a fast technique to assess the WSR waveform using an image of a pulsed Doppler waveform downloaded from a modern clinical ultrasound scanner. Methods A walled vascular phantom has been developed to mimic the physiological condition of brachial arteries, from where measurements were made. A MATLAB program has been developed and used to compute the WSR waveform in a flow phantom from a pulsed Doppler image. The mean WSR obtained from the WSR waveform was compared with the mean WSR derived from the flow rate obtained from a timed collection method. Measurement errors in Doppler velocity estimates from ultrasound scanners were also investigated and used to determine correction factors in WSR calculations. Results For three different flow phantom depths, 9.5,14.5 and 19.5 mm, the mean percentage errors between the true and measured WSR were found to be 4.5% (SD = 4.0), 7.4% (SD = 5.1) and 14.2% (SD = 4.1) respectively. Conclusions The results demonstrated the feasibility of calculating WSR based solely on an image of the Doppler spectrum and arterial diameter measurement, which opens up the possibility of obtaining WSR estimates from generic scanners.
An efficient post-hoc integration method improving peak alignment of metabolomics data from GCxGC/TOF-MS
Authors: Jeong Jaesik , Zhang Xiang , Shi Xue , Kim Seongho , Shen Changyu 
Published: April 2013

Abstract

Background
Since peak alignment in metabolomics has a huge effect on the subsequent statistical analysis, it is considered a key preprocessing step and many peak alignment methods have been developed. However, existing peak alignment methods do not produce satisfactory results. Indeed, the lack of accuracy results from the fact that peak alignment is done separately from another preprocessing step such as identification. Therefore, a post-hoc approach, which integrates both identification and alignment results, is in urgent need for the purpose of increasing the accuracy of peak alignment.

Results
The proposed post-hoc method was validated with three datasets such as a mixture of compound standards, metabolite extract from mouse liver, and metabolite extract from wheat. Compared to the existing methods, the proposed approach improved peak alignment in terms of various performance measures. Also, post-hoc approach was verified to improve peak alignment by manual inspection.

Conclusions
The proposed approach, which combines the information of metabolite identification and alignment, clearly improves the accuracy of peak alignment in terms of several performance measures. R package and examples using a dataset are available at http://mrr.sourceforge.net/download.html.

Published: April 2013

Abstract

Background
The recA/RAD51 gene family encodes a diverse set of recombinase proteins that affect homologous recombination, DNA-repair, and genome stability. The recA gene family is expressed across all three domains of life - Eubacteria, Archaea, and Eukaryotes - and even in some viruses. To date, efforts to resolve the deep evolutionary origins of this ancient protein family have been hindered by the high sequence divergence between paralogous groups (i.e. ~30% average pairwise identity).

Results
Through large taxon sampling and the use of a phylogenetic algorithm designed for inferring evolutionary events in highly divergent paralogs, we obtained a robust, parsimonious and more refined phylogenetic history of the recA/RAD51 superfamily.

Conclusions
In summary, our model for the evolution of recA/RAD51 family provides a better understanding of the ancient origin of recA proteins and the multiple events that lead to the diversification of recA homologs in eukaryotes, including the discovery of additional RAD51 sub-families.

Is it possible to stabilize a thermophilic protein further using sequences and structures of mesophilic proteins: a theoretical case study concerning DgAS
Authors: Liu Ming , He Hongqiu , Su Jiguo 
Published: April 2013

Abstract
Incorporating structural elements of thermostable homologs can greatly improve the thermostability of a mesophilic protein. Despite the effectiveness of this method, applying it is often hampered. First, it requires alignment of the target mesophilic protein sequence with those of thermophilic homologs, but not every mesophilic protein has a thermophilic homolog. Second, not all favorable features of a thermophilic protein can be incorporated into the structure of a mesophilic protein. Furthermore, even the most stable native protein is not sufficiently stable for industrial applications. Therefore, creating an industrially applicable protein on the basis of the thermophilic protein could prove advantageous. Amylosucrase (AS) can catalyze the synthesis of an amylose-like polysaccharide composed of only α-1,4-linkages using sucrose as the lone energy source. However, industrial development of AS has been hampered owing to its low thermostability. To facilitate potential industrial applications, the aim of the current study was to improve the thermostability of Deinococcus geothermalis amylosucrase (DgAS) further; this is the most stable AS discovered to date. By integrating ideas from mesophilic AS with well-established protein design protocols, three useful design protocols are proposed, and several promising substitutions were identified using these protocols. The successful application of this hybrid design method indicates that it is possible to stabilize a thermostable protein further by incorporating structural elements of less-stable homologs.
