Do Alternative Base Periods Increase Unemployment Insurance Receipt Among Low‐Educated Unemployed Workers?
Authors: Gould‐Werth Alix , Shaefer H. Luke 
Published: July 2013

AbstractUnemployment Insurance (UI) is the major social insurance program that protects against lost earnings resulting from involuntary unemployment. Existing literature finds that low‐earning unemployed workers experience difficulty accessing UI benefits. The most prominent policy reform designed to increase rates of monetary eligibility, and thus UI receipt, among these unemployed workers is the Alternative Base Period (ABP). In 2009, the American Recovery and Reinvestment Act sought to increase use of the ABP, making ABP adoption a necessary precondition for states to receive their share of the $7 billion targeted at UI programs. By January 2013, 40 states and the District of Columbia had adopted the ABP despite the absence of an evaluation of ABP efficacy using nationally representative data. This study analyzes Current Population Survey data from 1987 to 2011 to assess the efficacy of the ABP in increasing UI receipt among low‐educated unemployed workers. We used a natural‐experiment design to capture the combined behavioral and mechanical effects of the policy change. We found no association between state‐level ABP adoption and individual UI receipt for all unemployed workers. However, among part‐time unemployed workers with less than a high school degree, adoption of the ABP was associated with a 2.8 percentage point increase in the probability of UI receipt.
Using the concept of transient complex for affinity predictions in CAPRI rounds 20–27 and beyond
Authors: Qin Sanbo , Zhou Huan‐Xiang 
Published: July 2013

ABSTRACTPredictions of protein–protein binders and binding affinities have traditionally focused on features pertaining to the native complexes. In developing a computational method for predicting protein–protein association rate constants, we introduced the concept of transient complex after mapping the interaction energy surface. The transient complex is located at the outer boundary of the bound‐state energy well, having near‐native separation and relative orientation between the subunits but not yet formed most of the short‐range native interactions. We found that the width of the binding funnel and the electrostatic interaction energy of the transient complex are among the features predictive of binders and binding affinities. These ideas were very promising for the five affinity‐related targets (T43‐45, 55, and 56) of CAPRI rounds 20–27. For T43, we ranked the single crystallographic complex as number 1 and were one of only two groups that clearly identified that complex as a true binder; for T44, we ranked the only design with measurable binding affinity as number 4. For the nine docking targets, continuing on our success in previous CAPRI rounds, we produced 10 medium‐quality models for T47 and acceptable models for T48 and T49. We conclude that the interaction energy landscape and the transient complex in particular will complement existing features in leading to better prediction of binding affinities.

Assessment of CASP10 contact‐assisted predictions
Authors: Taylor Todd J. , Bai Hongjun , Tai Chin‐Hsien , Lee Byungkook 
Published: July 2013

ABSTRACTIn CASP10, for the first time, contact‐assisted structure predictions have been assessed. Sets of pairs of contacting residues from target structures were provided to predictors for a second round of prediction after the initial round in which they were given only sequences. The objective of the experiment was to measure model quality improvement resulting from the added contact information and thereby assess and help develop so‐called hybrid prediction methods—methods where some experimentally determined distance constraints are used to augment de novo computational prediction methods. The results of the experiment were, overall, quite promising. Proteins 2014; 82(Suppl 2):84–97. © 2013 Wiley Periodicals, Inc.
High‐gain observers in nonlinear feedback control
Authors: Khalil Hassan K. , Praly Laurent 
Published: July 2013

SUMMARYIn this document, we present the main ideas and results concerning high‐gain observers and some of their applications in control. The introduction gives a brief history of the topic. Then, a motivating second‐order example is used to illustrate the key features of high‐gain observers and their use in feedback control. This is followed by a general presentation of high‐gain‐observer theory in a unified framework that accounts for modeling uncertainty, as well as measurement noise. The paper concludes by discussing the use of high‐gain observers in the robust control of minimum‐phase nonlinear systems. Copyright © 2013 John Wiley & Sons, Ltd.
A capacity degradation model under interferences for sectorized cellular networks with fractional frequency reuse
Authors: Sheu Tsang‐Ling , Liu Kuo‐Liang , Chou Zi‐Tsan 
Published: July 2013

AbstractThis paper presents a capacity degradation model under interferences for sectorized cellular networks with fractional frequency reuse. In a sectorized fractional frequency reuse network, allocated bandwidth consists of a number of frequency partitions. To avoid intra‐cell interferences, each frequency partition is then assigned to two different groups, the super group (Sup‐G) and the regular group. However, because a Sup‐G in a cell employs the same frequency partition as the other Sup‐Gs in the neighboring cells, inter‐cell interferences may become serious when the radius of the Sup‐G is largely increased. In the worse case, the largely increasing inter‐cell interferences will eventually degrade the overall system capacity. Additionally, different density distributions of mobile stations may have different levels of impact on the capacity degradation. In this paper, both folded normal distribution and uniform distribution are considered in building the capacity degradation model. Numerical simulations show that by carefully adjusting the ratio between the radius of the Sup‐G and the radius of a cell, (i) an mobile station could receive the same capacity no matter where it is residing, and (ii) the maximum system capacity can be therefore achieved.

Do a country's logistical capabilities moderate the external integration performance relationship?
Authors: Wiengarten Frank , Pagell Mark , Ahmed Muhammad Usman , Gimenez Cristina 
Published: July 2013

AbstractCompanies have reacted to the opportunities and threats of globalization through numerous production practices that have increased supply chain complexity. One of the ways companies have been able to manage this increased level of complexity is by integrating their supply chains. Logistical capabilities at the company level play a key role in integrating global supply chains, but logistical capabilities need not be company specific. In this study we explore the role of a country's logistical capabilities in external supply chain integration. Our results indicate that plants situated in countries with superior levels of logistical capabilities adopt significantly lower levels of external supply chain integration. Additionally, plants situated in countries with superior logistical capabilities do not gain the same performance benefits from external integration as plants situated in countries with relatively low levels of logistical capabilities.

PurposeMetastasis, the main cause of death from cancer, remains poorly understood at the molecular level.Experimental designBased on a pattern of reduced expression in human prostate cancer tissues and tumor cell lines, a candidate suppressor gene (SPARCL1) was identified. We used in vitro approaches to determine whether overexpression of SPARCL1 affects cell growth, migration, and invasiveness. We then employed xenograft mouse models to analyze the impact of SPARCL1 on prostate cancer cell growth and metastasis in vivo.ResultsSPARCL1 expression did not inhibit tumor cell proliferation in vitro. By contrast, SPARCL1 did suppress tumor cell migration and invasiveness in vitro and tumor metastatic growth in vivo, conferring improved survival in xenograft mouse models.ConclusionsWe present the first in vivo data suggesting that SPARCL1 suppresses metastasis of prostate cancer.

BackgroundFalls and their associated injuries profoundly impact health outcomes, functional independence, and health care expenses, particularly for the ever‐increasing elderly population. This systematic search and review assessed the current evidence for the role of fall screening assessments.ObjectiveTo review the current evidence for fall risk screening assessments in community‐dwelling (outpatient), inpatient medical and surgical wards, inpatient rehabilitation centers, and postrehabilitation outpatient settings.Data SourcesMEDLINE and Embase (January 1980 to December 2012).Study SelectionProspective validation studies of acute medical or surgical inpatients, acute rehabilitation inpatients, outpatients who completed acute inpatient rehabilitation, or community‐dwelling elderly.Data ExtractionSensitivity, specificity, positive predictive value, negative predictive value, receiver operating characteristics with area under the curve.ResultsWe summarized key findings from 6 literature reviews. We then identified 31 articles: 12 studies in community setting, 13 in the acute medical inpatient or surgical inpatient setting, and 6 studies in the rehabilitation setting. Twenty‐two studies not previously reviewed were included, and 9 studies previously reviewed were considered relevant and were included to allow comparison with data from the studies not previously reviewed.ConclusionWe recommend consideration of 7 assessment tools to be used in conjunction with overall clinical evaluation to assess falls risk: the Timed Up and Go Test with a cutoff of >12.34 seconds and Functional Gait Assessment among community‐dwelling elderly; St Thomas Risk Assessment Tool in medical inpatients <65 years old and surgical inpatients; Hendrich fall risk model II in medical inpatients; 10‐Minute Walk Test in patients in poststroke rehabilitation; and Berg Balance Scale or the Step Test in patients in poststroke rehabilitation who had fallen during their inpatient stay.
Compliance and non-compliance as sources of recognition: Slovakia and NATO
Authors: Bátora Jozef 
Published: July 2013

This article argues that there is a difference in what constitutes the sources of recognition prior to countries’ membership in the Euro-Atlantic community represented by NATO and after countries become its members. While prior to membership, countries are recognized for their compliance with NATO standards and policies, upon membership countries get the opportunity to promote specific interests legitimately and may seek recognition via non-compliance with NATO mainstream.
The paper explores this dynamic of recognition on the issue of Kosovo independence where Slovakia went from supporting NATO in its effort to protect civilians in Kosovo in the late 1990s to non-recognition of Kosovo in defiance of the majority of NATO member states less than a decade later. The crucial point proposed here is that there was a shift in how recognition by NATO worked prior to Slovakia’s membership and upon membership in these frameworks. While prior to membership recognition was achieved by compliance and identification with NATO standpoints, policies and actions, upon membership, recognition is achieved by differentiation from these patterns. More generally, the study shows that NATO membership is a powerful source of conditionality in relation to future members and a powerful source of legitimacy in relation to current members’ actions. While this has been discussed in the literature, the point here is that recognition in its various forms is an important driving force in these conditionality processes.
Overmilking causes deterioration in teat-end condition of dairy cows in late lactation

Published: July 2013

The objective of the study was to determine the effect of varying degrees of overmilking on teat-end hyperkeratosis, milk production variables and indicators of udder health during late lactation. This was examined by assessing the effect of four end-of-milking criteria on 181 spring-calving, mixed-age Holstein-Friesian cows, at an average 217±24 d in milk, over a six-week period. The four treatments were: remove cluster once milk flow rate fell to 0·2 kg/min plus 5 s (Ovr0), plus 120 s (Ovr2), plus 300 s (Ovr5), and plus 540 s (Ovr9). Daily measurements included individual cow milk yield, milking duration, overmilking duration, maximum milk flow rate, milk flow rate at cluster removal and the number of cluster re-attachments. Individual cow bulk milk samples were collected weekly at AM and PM milkings to determine composition (fat, protein and lactose) and somatic cell count (SCC; AM only). Teat-end hyperkeratosis score was assessed at weeks 0, 3, 5 and 6. At week 6 mean teat-end hyperkeratosis score of the Ovr2 treatment was not greater than Ovr0, whilst Ovr5 was greater than Ovr2 and Ovr9 was greater than Ovr5 and Ovr2. Milk production, milking characteristics and SCC were not different between treatments, except milking duration and milk flow rate at cluster removal. However, higher teat-end hyperkeratosis scores may have a longer-term impact on indicators of udder health if teat-end condition reaches severe levels. Results indicate that to minimise changes in teat-end condition overmilking should be limited to 2 min, which has implications for milking management in large parlours not fitted with automatic cluster removers.
Pre-adjustment of adult attachment style to extrinsic risk levels via early attachment style is neither specific, nor reliable, nor effective, and is thus not an adaptation
Authors: Hönekopp Johannes 
Published: July 2013

AbstractThe mechanism proposed by Del Giudice by which adult attachment style is adapted to the extrinsic risk in the local environment via attachment style during the early years does not fulfill important criteria of an adaptation. The proposed mechanism is neither specific, nor developmentally reliable, nor effective. Therefore, it should not be considered an adaptation.
Is the second-step conditionalization unnecessary?
Authors: Liu In-mao 
Published: July 2013

AbstractBecause the addition of the conditional premise tends to increase modus ponens (MP) inferences, Oaksford & Chater argue that the additional knowledge is assimilated to world knowledge before the Ramsey test is carried out to evaluate P(q|p), so that the process of applying the Ramsey test could become indistinguishable from the process of applying the second-step conditionalization.
Uncertain premises and Jeffrey's rule
Authors: Over David E. , Hadjichristidis Constantinos 
Published: July 2013

AbstractOaksford & Chater (O&C) begin in the halfway Bayesian house of assuming that minor premises in conditional inferences are certain. We demonstrate that this assumption is a serious limitation. They additionally suggest that appealing to Jeffrey's rule could make their approach more general. We present evidence that this rule is not limited enough to account for actual probability judgements.
Testing for presence of known and unknown molecules in imaging mass spectrometry
Authors: Alexandrov Theodore , Bartels Andreas 
Published: July 2013

Abstract
Motivation: Imaging mass spectrometry has emerged in the past decade as a label-free, spatially resolved and multi-purpose bioanalytical technique for direct analysis of biological samples. However, solving two everyday data analysis problems still requires expert judgment: (i) the detection of unknown molecules and (ii) the testing for presence of known molecules.
Results: We developed a measure of spatial chaos of a molecular image corresponding to a mass-to-charge value, which is a proxy for the molecular presence, and developed methods solving considered problems. The statistical evaluation was performed on a dataset from a rat brain section with test sets of molecular images selected by an expert. The measure of spatial chaos has shown high agreement with expert judges. The method for detection of unknown molecules allowed us to find structured molecular images corresponding to spectral peaks of any low intensity. The test for presence applied to a list of endogenous peptides ranked them according to the proposed measure of their presence in the sample.

Abstract
Lassalle, G., Nelva Pasqual, J-S., Boët, P., Rochet, M-J., Trenkel, V. M., and Niquil, N. Combining quantitative and qualitative models to identify functional groups for monitoring changes in the Bay of Biscay continental shelf exploited foodweb. – ICES Journal of Marine Science, 71: . To develop and implement ecosystem-based management, it is critical to monitor foodweb components or functional groups which are robust to uncertainty in ecosystem structure and functioning yet sensitive to changes. To select such functional groups for the Bay of Biscay continental shelf, both quantitative and qualitative foodweb models were developed. First, functional groups for which predictions of directions of change following an increase in primary productivity, prey or predators, or in fishing activities were identical across alternative qualitative model structures were identified. Second, the robustness to model type was assessed by comparing qualitative predictions with quantitative Ecopath model results. The demersal fish community was identified as a sensitive and robust indicator for monitoring foodweb ecological status in the Bay of Biscay. The present study also suggested the potential antagonistic effects of alternative management measures on small pelagic fish and highlighted the need for the joint management of all pressures.

Abstract
Previous research reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate dioxygenase (HPPD) herbicides in a waterhemp (Amaranthus tuberculatus) population designated MCR (for McLean County mesotrione- and atrazine-resistant). Herein, experiments were conducted to determine if target site or nontarget site mechanisms confer mesotrione resistance in MCR. Additionally, the basis for atrazine resistance was investigated in MCR and an atrazine-resistant but mesotrione-sensitive population (ACR for Adams County mesotrione-sensitive but atrazine-resistant). A standard sensitive population (WCS for Wayne County herbicide-sensitive) was also used for comparison. Mesotrione resistance was not due to an alteration in HPPD sequence, HPPD expression, or reduced herbicide absorption. Metabolism studies using whole plants and excised leaves revealed that the time for 50% of absorbed mesotrione to degrade in MCR was significantly shorter than in ACR and WCS, which correlated with previous phenotypic responses to mesotrione and the quantity of the metabolite 4-hydroxy-mesotrione in excised leaves. The cytochrome P450 monooxygenase inhibitors malathion and tetcyclacis significantly reduced mesotrione metabolism in MCR and corn (Zea mays) excised leaves but not in ACR. Furthermore, malathion increased mesotrione activity in MCR seedlings in greenhouse studies. These results indicate that enhanced oxidative metabolism contributes significantly to mesotrione resistance in MCR. Sequence analysis of atrazine-resistant (MCR and ACR) and atrazine-sensitive (WCS) waterhemp populations detected no differences in the psbA gene. The times for 50% of absorbed atrazine to degrade in corn, MCR, and ACR leaves were shorter than in WCS, and a polar metabolite of atrazine was detected in corn, MCR, and ACR that cochromatographed with a synthetic atrazine-glutathione conjugate. Thus, elevated rates of metabolism via distinct detoxification mechanisms contribute to mesotrione and atrazine resistance within the MCR population.
Remifentanil as analgesia for labour pain
Authors: TVEIT TOR O. 
Published: July 2013

BackgroundTo collect updated information about pharmacological labour analgesia in Norway, especially systemic opioids and epidural. Evaluation of efficacy and safety with remifentanil intravenous patient‐controlled analgesia (IVPCA) for pain relief during labour. To compare remifentanil IVPCA with epidural analgesia (EDA) regarding efficacy and safety during labour.MethodsIn paper I, two national surveys identified Norwegian labour analgesia methods and changes during the study period (2005–2008). Paper II is a prospective, observational study of analgesic efficacy and safety with remifentanil IVPCA. Paper III is a prospective, randomized controlled trial comparing remifentanil IVPCA with EDA regarding analgesic efficacy and safety.ResultsThe surveys in paper I found the frequency of EDA in Norwegian hospitals to be increasing, but still low (25.9%) compared with other western countries. Nitrous oxide and traditional systemic opioids, like pethidine, were frequently used. In paper II, remifentanil IVPCA was found to give satisfactory labour analgesia in more than 90% of the parturients with an average maximal pain reduction of 60%. Maternal oxygen desaturation and sedation were acceptable, and neonatal data reassuring. In paper III, a randomized controlled trial found remifentanil IVPCA and EDA to be comparable both regarding analgesic efficacy (pain reduction; Fig. ) and maternal satisfaction. Remifentanil IVPCA produced more maternal sedation and oxygen desaturation; neonatal outcome was reassuring in both groups.Reduction in pain score [visual analogue scale (VAS)] during labour analgesia with patient‐controlled intravenous remifentanil and continuous epidural infusion with ropivacaine and fentanyl.figureConclusionThe frequency of epidural labour analgesia in Norway has increased, but is still relatively low. Nitrous oxide and traditional systemic opioids are frequently used. The clinical practice seems conservative; newer short‐acting opioids are seldom used for systemic labour analgesia. The studies on remifentanil IVPCA revealed adequate pain relief, high maternal satisfaction, and no serious neonatal side effects. There were no differences in analgesic efficacy, maternal satisfaction, and neonatal outcome when comparing remifentanil IVPCA with EDA. However, remifentanil caused maternal sedation and oxygen desaturation. We recommend the use of IVPCA remifentanil as labour analgesia instead of traditional opioids as pethidine and morphine when EDA is not an option. The presence of skilled personnel and close monitoring is mandatory.
