The retiree identity: gender and race differences.

OBJECTIVES This study's focus on the retiree identity complements research on institutionalized retirement criteria. We test whether tensions between individuals' own life circumstances and institutionalized retirement criteria manifest themselves in the extent to which individuals assume a retiree identity and in the overlap between self-definitions and attainment of institutionalized retirement criteria. METHODS The analyses rely on logistic regressions and are based on data from the National Survey of Families and Households (N = 1,633). RESULTS Labor force participation serves as the main basis for the retiree identity, but other life experiences (work history, disability, spouse's retirement, economic status, family history) also contribute to individuals' self-identification as retiree and the "fit" between self-identification and attainment of institutionalized retirement criteria. Men's retirement identity seems more closely tied to their attainment of institutionalized retirement criteria and a continuous and successful work career, whereas a variety of life circumstances impinge on women's retiree definitions. Moderately disabled African Americans are more likely to self-identify as partly or fully retired. DISCUSSION While employment constitutes the main reference for individuals' self-definition as retiree, other life circumstances also have some influence. Full understanding of retirement transitions will require more attention to the meaning context of retirement among divergent population groups.
The Impact of Stock Prices, Risks and Business Cycle on Overconfidence

Previous researches show that investors are not completely rational. Overconfidence is one of the investors irrationalities that have drawn special attention from academics. This study adopts the method of [1] to investigate the relationship between the overconfidence and stock prices, risks and business cycle in the Taiwan stock market. We find that returns in the previous period are positively correlated with turnover rates of the current period, a result consistent with previous researches that investors in the Taiwan stock market exhibit overconfidence. In addition, investors are more likely to have more overconfidence in low-priced stocks than in high-priced stocks and more likely to have more overconfidence in high-risk stocks than low-risk stocks. Investors overconfidence is also more likely to occur in the bull market than in the bear market.
Subsidiary Upgrading?: Strategic Inertia in the Development of German-owned Subsidiaries in Hungary

This study reports the results of interviews with 65 managers in 11 German headquarters and in their 13 Hungarian subsidiaries. We focused on the role of the subsidiary with regard to market, product and value-adding mandates. Further, we investigated whether the Hungarian subsidiaries had experienced an upgrade of their role during the first 10 years of transition. The host country economy was supportive to role development, but inadequate subsidiary capabilities and headquarters’ assignments prevented the subsidiaries from being upgraded. We propose that the corporate immune system, ie, ethnocentric behaviours emanating from the headquarters should be included in future upgrading analyses.
Anti-ESL/ESR variation robust constant-on-time control for DC-DC buck converter in 28nm CMOS technology

Conventional constant-on-time (COT) control for DC-DC buck converter is apt to be affected by the noise caused by parasitic effect including not properly specified and temperature dependent equivalent series resistance (ESR) and equivalent series inductance (ESL). As a result, the safety operation area (SOA) of the COT is limited by the selection of external components. In this paper, the calibrated anti-ESL (CAESL) technique and the calibrated gain and BW (CGB) technique for alleviating ESL and ESR variation, respectively, are proposed to ensure a robust COT control. Furthermore, degraded output regulation caused by enlarged ESL effect due to input battery voltage variation is also solved by the CAESL technique. The proposed COT converter fabricated in 28nm CMOS technology uses an output capacitor with an ESR smaller than 1mΩ, output ripple of 20mV, and high efficiency higher than 95%. The CAESL circuit can tolerate ESL voltage variation from 0 to 50mV even when operation temperature varies from -40 to 120°C.
MS-Aloha: Preliminary analysis of its suitability for wireless automation

This paper deals with the adoption of wireless communications in industrial automation. Most diffuse wireless systems require the deployment of a fixed infrastructure, with sufficient nodes acting as coordinators; this approach is typically applied also in automation. Conversely, a decentralized wireless solution is here proposed: it is based on a synchronous and connection-oriented protocol studied for vehicular communications. The protocol, called MS-Aloha, guarantees a multi-hop coordination with dynamic resource reservation, spatial slot re-use and hidden terminals prevention. The proposed solution has been modeled and simulated in order to quantitatively demonstrate how much its determinism and multi-hop coordination can be beneficial to the automation, in comparison to CSMA/CA. The simulated scenarios address the evaluation of the latency, delay variation, and delivery rate in critical conditions involving hidden terminals and close to congestion.
A Novel Technique of Neuropathy Detection and Classification by using Artificial Neural Network ( ANN )

Nerve conduction study (NCS) assists the neurophysiologist with evaluation of neuropathy. Electromyography (EMG) is another tool which helps in detection of neuropathy by supplementing some additional information. This study was done on nerve conduction study (NCS) data collected from 366 patients attending deptt of Neurophysiology, GNRC hospital, Sixmiles, Guwahati, during the period of 2008 to 2009.The data set was then subdivided into sets at ratio 60:20:20 and formed three matrices and then subjected to 3 different Artificial Neural Network (ANN) processing. ANN is a promising tool for medical diagnosis that shows a higher level of classification. The first set was used to train the ANNs and the other two sets were used for validation and testing respectively. The results were analyzed depending on different parameters such as accuracy, sensitivity, specificity. It was found that the best performing model is feedforward back propagation (FFBP) which has a higher accuracy than other two ANN models and also has a higher classification speed. It can be concluded that ANN analysis offers a promising implementation to establish methods of practically useful systemic tool of multivariate data analysis of neuropathy patients for detection and classification of neuropathy. This paper describes a novel method of neuropathy detection and classification using Artificial Neural Network.
An Analytical Study On Women’s Empowerment Regarding Decision Making: A Case Study Of Pakistan

Pakistan is a country where women are half in population, but women have less opportunity to have empowerment regarding decision making. Women remain under male domination, and various social, cultural and economic disparities. In Pakistan, they are not empowered. Women’s involvement in domestic decision-making has recognized for family development. This study was conducted to analyses the women empowerment at social, educational and political level. The objectives were to discern the status of women empowerment in political organizations, to recommend the status of women empowerment, to highlight empowerment of women in educational fields and to investigate women’s role in decision making at social level. Research question were, what is women empowerment status with respect to decision making in politics, how to empower women in decision making at social level, how decision making of empowered women influences on the educational institutes and how the women of our society be empowered? Mixed method approach was used to collect the data, survey questionnaire, and interview and document analysis. Sample of the study was 110 working and 110 non-working women, 30 political women. (N=250).
Accumulation of spontaneous γH2AX foci in long-term cultured mesenchymal stromal cells

Expansion of mesenchymal stromal/stem cells (MSCs) used in clinical practices may be associated with accumulation of genetic instability. Understanding temporal and mechanistic aspects of this process is important for improving stem cell therapy protocols. We used γH2AX foci as a marker of a genetic instability event and quantified it in MSCs that undergone various numbers of passage (3-22). We found that γH2AX foci numbers increased in cells of late passages, with a sharp increase at passage 16-18. By measuring in parallel foci of ATM phosphorylated at Ser-1981 and their co-localization with γH2AX foci, along with differentiating cells into proliferating and resting by using a Ki67 marker, we conclude that the sharp increase in γH2AX foci numbers was ATM-independent and happened predominantly in proliferating cells. At the same time, gradual and moderate increase in γH2AX foci with passage number seen in both resting and proliferating cells may represent a slow, DNA double-strand break related component of the accumulation of genetic instability in MSCs. Our results provide important information on selecting appropriate passage numbers exceeding which would be associated with substantial risks to a patient-recipient, both with respect to therapeutic efficiency and side-effects related to potential neoplastic transformations due to genetic instability acquired by MSCs during expansion.

Association Between Neonatal Urinary Tract Infection and Risk of Childhood Allergic Rhinitis

AbstractThe current population-based study investigated the onset of neonatal urinary tract infection (UTI) and the associated risks of allergic rhinitis.From 2000 to 2005, 3285 children with neonatal UTI and 13,128 randomly selected controls were enrolled from the National Health Insurance Research Database in Taiwan and frequency matched by gender, urbanization of residential area, parental occupation, and baseline year. We compared the risk of allergic rhinitis between the non-UTI and UTI cohorts by performing multivariable Cox regression analysis.We observed a significant relationship between UTI and allergic rhinitis. This study examined 16,413 patients, among whom 3285 had UTI and 13,128 did not have UTI. The overall incidence rate ratio of allergic rhinitis was 1.41-fold higher in the UTI cohort than in the non-UTI cohort (100.2 vs 70.93 per 1000 person-y). After potential risk factors were adjusted for, the adjusted hazard ratio of allergic rhinitis was 1.32 (95% confidence interval = 1.23–1.41). Regardless of gender, the UTI cohort had a higher risk of allergic rhinitis than that of the non-UTI cohort. The patients with UTI in different follow-up durations were equally susceptible to developing allergic rhinitis compared with those without UTI, especially in follow-up durations shorter than 5 years. Patients with UTI and particular comorbidities such as infections and neonatal jaundice had a significantly increased risk of allergic rhinitis.UTI in newborns is significantly associated with the development of allergic rhinitis in childhood and might be a risk factor for subsequent childhood allergic rhinitis.
Fast Optimal Decoding of Multiplexed Orthogonal Designs by Conditional Optimization

This paper focuses on conditional optimization as a decoding primitive for high rate space-time codes that are obtained by multiplexing in the spatial and code domains. The approach is a crystallization of the work of Hottinen which applies to space-time codes that are assisted by quasi-orthogonality. It is independent of implementation and is more general in that it can be applied to space-time codes such as the Golden Code and perfect space-time block codes, that are not assisted by quasi-orthogonality, to derive fast decoders with essentially maximum likelihood (ML) performance. The conditions under which conditional optimization leads to reduced complexity ML decoding are captured in terms of the induced channel at the receiver. These conditions are then translated back to the transmission domain leading to codes that are constructed by multiplexing orthogonal designs. The methods are applied to several block space-time codes obtained by multiplexing Alamouti blocks where it leads to ML decoding with complexity O(N 2) where N is the size of the underlying QAM signal constellation. A new code is presented that tests commonly accepted design principles and for which decoding by conditional optimization is both fast and ML. The two design principles for perfect space-time codes are nonvanishing determinant of pairwise differences and cubic shaping, and it is cubic shaping that restricts the possible multiplexing structures. The new code shows that it is possible to give up on cubic shaping without compromising code performance or decoding complexity.
La parlementarisation de l'Union : pour une approche dynamique du régime politique européen

Ce memoire part du constat de la difficulte persistante qu'il y a a modeliser le systeme politique de l'Union europeenne. Pour la surmonter, nous proposons d'analyser ce regime comme etant en voie de " parlementarisation ", c'est-a-dire comme tendant a se rapprocher du type de regime que connaissent les democraties contemporaines. A ce titre, on evaluera d'abord les progres realises par l'Union a l'aune de differents criteres : le caractere democratique de ce regime, la montee en puissance des pouvoirs du Parlement europeen, et l'evolution des rapports interinstitutionnels. On se penchera ensuite sur le role que jouent aujourd'hui les acteurs politiques (deputes europeens, groupes politiques, partis politiques europeens) dans le fonctionnement de l'Union. Enfin, on tentera d'objectiver la montee en puissance du Parlement europeen dans la fabrique des politiques de l'Union, en pretant une attention particuliere au developpement des trilogues interinstitutionnels. On conclura sur l'emergence d'un systeme institutionnel quadripartite original.
79-GHz LTCC RF-frontend deploying 45 degree linear-polarized vertical parallel-feed antennas

This paper presents a 79-GHz RF-frontend realized in low-temperature co-fired ceramics (LTCC) technology. The frontend is designed for the short range radar (SRR) applications. For the radar antenna, a laminated waveguide (LWG) was chosen as transmission line due to its low conductor loss and a 45° linear-polarization was used to reduce interferences. Further, an LWG-based vertically oriented parallel feeding-network helps to keep the antenna main-beam direction constant across the 4 GHz bandwidth. A four-channel SiGe radar transceiver chip was applied to build the frontend. Combing the multiple-input multiple-output concept with virtual antennas, the aperture of the radar was enlarged. To verify theory, the RF-frontend was fabricated and measured with a baseband-board. The radar achieves a range resolution of about 8 cm, a minimum angle resolution of 10° and a field-of-view of 120°. The frontend has a dimension of 23 mm × 30 mm × 1.7 mm and in total 15 layers of ceramic tapes were used. This compact LTCC RF-frontend is suitable for the 79 GHz SRR applications. Index Terms-LTCC, Radar, Frontend, Antenna.
Nuclear Export of Messenger RNA

Transport of messenger RNA (mRNA) from the nucleus to the cytoplasm is an essential step of eukaryotic gene expression. In the cell nucleus, a precursor mRNA undergoes a series of processing steps, including capping at the 5' ends, splicing and cleavage/polyadenylation at the 3' ends. During this process, the mRNA associates with a wide variety of proteins, forming a messenger ribonucleoprotein (mRNP) particle. Association with factors involved in nuclear export also occurs during transcription and processing, and thus nuclear export is fully integrated into mRNA maturation. The coupling between mRNA maturation and nuclear export is an important mechanism for providing only fully functional and competent mRNA to the cytoplasmic translational machinery, thereby ensuring accuracy and swiftness of gene expression. This review describes the molecular mechanism of nuclear mRNA export mediated by the principal transport factors, including Tap-p15 and the TREX complex.

A Search-Based Theory of the On-the-Run Phenomenon

We propose a model in which assets with identical cash flows can trade at different prices. Infinitely-lived agents can establish long positions in a search spot market, or short positions by first borrowing an asset in a search repo market. We show that short-sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed. That asset enjoys greater liquidity, measured by search times, and a higher lending fee ("specialness"). Liquidity and specialness translate into price premia that are consistent with no-arbitrage. We derive closed-form solutions for small frictions, and can generate price differentials in line with observed on-the-run premia.
A Genetic Algorithm for K-node Set Reliability Optimization with Capacity Constraint of a Distributed System

In the reliability analysis of a distributed system (DS), k-node set reliability is defined as the probabilities that all the nodes in K are connected, where K denotes a subset of a set of processing elements. A k-node set reliability computation can be very difficult to perform with exponential in many cases. A k-node set reliability optimization with a capacity constraint problem is to select a k-node set of nodes in a distributed system such that the k-node set reliability is maximal and possesses sufficient node capacity. It is evident that this is an NP-hard problem. Relative investigation, namely exact method, has examined k-node set reliability optimization with capacity constraint. Although the exact method can obtain an optimal solution, it cannot reduce the computational time. Occasionally, an efficiency algorithm with an exact or nearly exact solution is attractive. Thus, in this paper, we present a method based on a genetic algorithm used to evolve the best k-node sets. Because the final number of best k-node sets is only one, less time is needed to compute the reliability of the k-node set. The exact solution can be obtained in most cases using the proposed method. When it fails to give an exact solution, the deviation from the exact solution is very small. In addition, the proposed algorithm is compared with the exact method for various DS topologies. The results demonstrate that the proposed algorithm is more efficient in execution time. In summary, the proposed algorithm can efficiently obtain the maximal or near maximal k-node set reliability with a capacity constraint.

Are Red or Blue Companies More Likely to Go Green? Politics and Corporate Social Responsibility

Using the firm-level corporate social responsibility (CSR) ratings of Kinder, Lydenberg, Domini, we find that firms score higher on CSR when they have Democratic rather than Republican founders, CEOs, and directors, and when they are headquartered in Democratic rather than Republican-leaning states. Democratic-leaning firms spend $20 million more on CSR than Republican-leaning firms ($80 million more within the sample of S&P 500 firms), or roughly 10% of net income. We find no evidence that firms recover these expenditures through increased sales. Indeed, increases in firm CSR ratings are associated with negative future stock returns and declines in firm ROA, suggesting that any benefits to stakeholders from social responsibility come at the direct expense of firm value.
