HR practices, commitment, job performance and early retirement among older employees with an on average low occupational status

This study examined the influence of the perception of the quality of HR practices on job performance, commitment and a preference for early retirement among older employees, with an average low occupational status in the creative industry in the Netherlands, This study has adopted a mixed-methods approach, using both surveys and semi-structured interviews. Using the principles underlying social exchange theory, it was expected that perceived quality of HR practices would have a positive relationship with job performance and affective organizational commitment and a negative relationship with a preference for early retirement. Perceived quality of certain HR practices seemed to have a positive relationship with job performance and affective organizational commitment. However, in contradiction with the social exchange theory, perceived quality of HR practices was found to be unrelated to a preference for early retirement. An explanation of this lmexpected finding arose from the qualitative study: older employees perceive the provision of HR practices for older employees as a stamp that they now belong to this devalued social group, which can be explained by the social identity theory. It was found that for older employees with an average low occupational status personal factors like finances and health strongly influenced the retirement decision. On the organizational level, flexibility, communication and a mentality change towards older employees seemed important in this decision. The qualitative study could explain the unexpected findings of the quantitative study, showing the contribution of a mixed-methods, approach. Theoretically, this raises the question whether social exchange theory applies to older employees with an average low occupational status and shows that the social identity theory better explains the relationship between perceived quality of HR practices and a preference for early retirement.
Classifying News Headlines for Providing User Centered E-Newspaper Using SVM

: Recommending news is very active research fileld. As the popularity of the Internet, the number of online newspapers is incerased in last few days. In this regard it is very difficult for the user to access the news articles of his interests in digital newspaper. In this paper we propose a SVM based news personalisation system that aims at recommending news to the users as per their interests which are predefined in their profiles. The model considers news headlines which are classified in various categories using SVM. These classified news headlines are posted to the users according to their choices. We have evaluated the performance of the system using 20 Newsgropu Dataset as well as using the real time dataset from the Times of Indis news website.
Personal identification based on finger vein and contour point clouds matching

Finger vein recognition has attracted increasing attention in biometric identification field. To solve the problems of lack of depth information in recognition based on 2D image and no enough obvious features used for recognition based on 3D point cloud, a novel approach of identifying individuals using 3D point clouds matching of finger vein and contour is proposed in this paper. A pair of vein images of a finger are captured under Near Infrared(NIR) light using our binocular vision device. The edge and vein contours of finger are extracted as features used for describe finger vein and then 3D point cloud of finger vein and contour is reconstructed though binocular vision technique. At last, personal identification based on matching results between template and reconstructed 3D point cloud using Iterative Closest Point(ICP) algorithm can be achieved. The experimental results show that proposed method can generate more discriminative features to represent 3D model of finger vein and contour so that the accuracy of matching is enhanced.
Poly-LacNAc as an Age-Specific Ligand for Rotavirus P[11] in Neonates and Infants

Rotavirus (RV) P[11] is an unique genotype that infects neonates. The mechanism of such age-specific host restriction remains unknown. In this study, we explored host mucosal glycans as a potential age-specific factor for attachment of P[11] RVs. Using in vitro binding assays, we demonstrated that VP8* of a P[11] RV (N155) could bind saliva of infants (60.3%, N = 151) but not of adults (0%, N = 48), with a significantly negative correlation between binding of VP8* and ages of infants (P<0.01). Recognition to the infant saliva did not correlate with the ABO, secretor and Lewis histo-blood group antigens (HBGAs) but with the binding of the lectin Lycopersicon esculentum (LEA) that is known to recognize the oligomers of N-acetyllactosamine (LacNAc), a precursor of human HBGAs. Direct evidence of LacNAc involvement in P[11] binding was obtained from specific binding of VP8* with homopolymers of LacNAc in variable lengths through a glycan array analysis of 611 glycans. These results were confirmed by strong binding of VP8* to the Lec2 cell line that expresses LacNAc oligomers but not to the Lec8 cell line lacking the LacNAc. In addition, N155 VP8* and authentic P[11] RVs (human 116E and bovine B223) hemagglutinated human red blood cells that are known to express poly-LacNAc. The potential role of poly-LacNAc in host attachment and infection of RVs has been obtained by abrogation of 116E replication by the PAA-conjugated poly-LacNAc, human milk, and LEA positive infant saliva. Overall, our results suggested that the poly-LacNAc could serve as an age-specific receptor for P[11] RVs and well explained the epidemiology that P[11] RVs mainly infect neonates and young children.
Changes in common carotid artery intima-media thickness over 1 year in patients on peritoneal dialysis.

BACKGROUND Accelerated atherosclerosis and vascular calcifications increase cardiovascular morbidity and mortality in patients on dialysis. Common carotid artery (CCA) intima-media thickness (IMT) is considered useful for imaging atherosclerosis non-invasively. Since chronic inflammation may accelerate atherosclerosis in end-stage renal disease patients, the aim of this 1 year study was to assess changes in CCA-IMT in stable peritoneal dialysis (PD) patients, and to search for possible associations between these changes and selected cytokines, acute phase proteins and other risk factors of atherosclerosis. METHODS Of the original cohort of 61 stable patients on PD-28 female, 33 male; mean age 50.4+/-13.6 years; dialyse for a median of 17.5 months at inclusion (range 1-96 months)-47 patients survived the 1 year period on PD. CCA-IMT was assessed at baseline and after 12 months. Pro-inflammatory cytokines (IL-6, TNFalpha), acute phase proteins (CRP, fibrinogen), calcium-phosphate balance and lipid profile were assessed at baseline and after 6 and 12 months. Anthropometric parameters (age, weight, BMI, waist-to-hip ratio) were measured at baseline. RESULTS The mean CCA-IMT at baseline, 0.66+/- 0.19 mm, increased by a mean of 0.098+/-0.17 to 0.76+/-0.21 mm (P<0.001) in 1 year. In 14 patients (29.8%) at least one plaque was found in the CCAs examined. At the end of follow-up: 28 patients (59.6%) had increases in CCA-IMT (from 0.63+/-0.2 to 0.83+/- 0.21 mm; P = 0.03), and 19 (40.4%) remained stable or even showed slight, but non-significant, decreases of CCA-IMT (from 0.72+/-0.17 to 0.66+/-0.17 mm, P = NS). The 'progressors' had significantly higher initial BMI (P<0.05), and mean concentrations of calcium (P = 0.005), IL-6 (P = 0.05), TNFalpha (P = 0.05), CRP (P = 0.005) and lower HDL-cholesterol than 'non-progressors'. In univariate analysis, DeltaCCA-IMT correlated positively with age (R = 0.32, P = 0.03), BMI (R = 0.29, P = 0.05) and mean concentrations of CRP (R = 0.37, P = 0.01), TNFalpha (0.52, P = 0.0002), but inversely with HDL-cholesterol (R = -0.37, P = 0.01). In multiple regression analysis, however, only age appeared to be independently associated with increase in CCA-IMT (beta = 0.37, P<0.01; R(2) for the model 0.14). CONCLUSIONS Our results suggest a possible role of non-specific inflammation in the progression of atherosclerosis in patients treated with PD, in addition to age.

Towards Exploring Factors Affecting Decision Outcome and Lead-time in Large-Scale Requirements Engineering

SUMMARY Lead-time is crucial for decision–making in market-driven requirements engineering. Lead-time efﬁciency allows software companies to focus their resources on the most proﬁtable functionality, and enables to remain competitive on the fast-changing software market. Achieving and sustaining low decision lead-time and the resulting high decision efﬁciency, requires better understanding of factors that may affect both decision lead-time and outcome. In order to identify possible factors, we conducted an exploratory two-stage case study that combines the statistical analysis of seven possible relationships among decision characteristics at a large company with a survey among industry participants. Our results show that the number of products affected by a decision increases the time needed to make a decision. Practitioners should take this aspect into consideration when planning for efﬁcient decision–making and possibly reducing the complexity of decisions. Our results also show that when a change request originates from an important customer, the request is more quickly accepted. The result provides input into the discussion if a large company should only focus on few yet large customers and disregard a signiﬁcantly large group of small customers. Our results provide valuable insights for both researchers, who can use them to plan research of decision–making processes and methods, and for practitioners, who can use them to optimize their decision– making processes.
What do Dutch general education teachers do to facilitate the social participation of students with SEBD?

ABSTRACT Few studies have addressed the daily practice of applied teacher strategies aimed at facilitating the social participation of students with social-emotional problems or behavioural difficulties (SEBD). In this paper, we present two interlinked studies that address this topic. The main study reports on the development of the Teacher Strategy Questionnaire on Social Participation in the Classroom (TSQ-SPC). We tested the questionnaire’s construct validity by performing a second-order confirmatory factor analysis. The follow-up study presents the results of a survey of 163 Dutch general primary education teachers of inclusive classes using a modified version of the TSQ-SPC. It provides insights on the strategies that teachers apply in their daily practice to facilitate positive social participation of students with SEBD. The findings of both studies suggest that general primary education teachers apply a limited repertoire of strategies. Accordingly, there is an urgent need for further research focusing on the development of interventions and revisions of the pre- and in-service teacher development curricula aimed at adequately supporting and preparing general education teachers.
A breath fungal secondary metabolite signature to diagnose invasive aspergillosis.

BACKGROUND Invasive aspergillosis (IA) remains a leading cause of mortality in immunocompromised patients, in part due to the difficulty of diagnosing this infection. METHODS Using thermal desorption-gas chromatography/mass spectrometry, we characterized the in vitro volatile metabolite profile of Aspergillus fumigatus, the most common cause of IA, and other pathogenic aspergilli. We prospectively collected breath samples from patients with suspected invasive fungal pneumonia from 2011 to 2013, and assessed whether we could discriminate patients with proven or probable IA from patients without aspergillosis, as determined by European Organization for Research and Treatment of Cancer/Mycoses Study Group consensus definitions, by direct detection of fungal volatile metabolites in these breath samples. RESULTS The monoterpenes camphene, α- and β-pinene, and limonene, and the sesquiterpene compounds α- and β-trans-bergamotene were distinctive volatile metabolites of A. fumigatus in vitro, distinguishing it from other pathogenic aspergilli. Of 64 patients with suspected invasive fungal pneumonia based on host risk factors, clinical symptoms, and radiologic findings, 34 were diagnosed with IA, whereas 30 were ultimately diagnosed with other causes of pneumonia, including other invasive mycoses. Detection of α-trans-bergamotene, β-trans-bergamotene, a β-vatirenene-like sesquiterpene, or trans-geranylacetone identified IA patients with 94% sensitivity (95% confidence interval [CI], 81%-98%) and 93% specificity (95% CI, 79%-98%). CONCLUSIONS In patients with suspected fungal pneumonia, an Aspergillus secondary metabolite signature in breath can identify individuals with IA. These results provide proof-of-concept that direct detection of exogenous fungal metabolites in breath can be used as a novel, noninvasive, pathogen-specific approach to identifying the precise microbial cause of pneumonia.
A Riemannian low-rank method for optimization over semidefinite matrices with block-diagonal constraints

We propose a new algorithm to solve optimization problems of the form min f (X) for a smooth function f under the constraints that X is positive semidefinite and the diagonal blocks of X are small identity matrices. Such problems often arise as the result of relaxing a rank constraint (lifting). In particular, many estimation tasks involving phases, rotations, orthonormal bases or permutations fit in this framework, and so do certain relaxations of combinatorial problems such as Max-Cut. The proposed algorithm exploits the facts that (1) such formulations admit low-rank solutions, and (2) their rank-restricted versions are smooth optimization problems on a Riemannian manifold. Combining insights from both the Riemannian and the convex geometries of the problem, we characterize when second-order critical points of the smooth problem reveal KKT points of the semidefinite problem. We compare against state of the art, mature software and find that, on certain interesting problem instances, what we call the staircase method is orders of magnitude faster, is more accurate and scales better. Code is available.
Long-Lasting Immune Protection and Other Epidemiological Findings after Chikungunya Emergence in a Cambodian Rural Community, April 2012

The East/Central/South African genotype of Chikungunya virus with the E1-A226V mutation emerged in 2011 in Cambodia and spread in 2012. An outbreak of 190 cases was documented in Trapeang Roka, a rural village. We surveyed 425 village residents within 3–4 weeks after the outbreak, and determined the sensitivity and specificity of case definitions and factors associated with infection by CHIKV. Self-reported clinical presentation consisted mostly of fever, rash and arthralgia. The presence of all three clinical signs or symptoms was identified as the most sensitive (67%) and specific (84%) self-reported diagnostic clinical indicator compared to biological confirmation by MAC-ELISA or RT-PCR used as a reference. Having an indoor occupation was associated with lower odds of infection compared with people who remained at home (adjOR 0.32, 95%CI 0.12–0.82). In contrast with findings from outbreaks in other settings, persons aged above 40 years were less at risk of CHIKV infection, likely reflecting immune protection acquired when Chikungunya circulated in Cambodia before the Khmer Rouge regime in 1975. In view of the very particular history of Cambodia, our epidemiological data from Trapeang Roka are the first to support the persistence of CHIKV antibodies over a period of 40 years.
Understanding the Risk-Return Tradeoff in the Stock Market

We find that past stock market variance forecasts excess stock market returns and that its predictive ability is greatly enhanced if the consumption-wealth ratio is also included in the forecasting equation. While the risk-return tradeoff is found negative if we use the latter as the instrumental variable for the conditional moments, the former suggests a positive one. We argue that the consumption-wealth ratio is closely related to the hedge component of excess returns as in Merton’s (1973) intertemporal capital asset pricing model: market risk is indeed positively priced if we control for the hedge component.

MOR1, the Arabidopsis thaliana homologue of Xenopus MAP215, promotes rapid growth and shrinkage, and suppresses the pausing of microtubules in vivo

MOR1, the Arabidopsis thaliana homologue of the Xenopus microtubule-associated protein MAP215, is required for spatial organization of the acentrosomal microtubule arrays of plant cells. To determine how loss of MOR1 function affects microtubule dynamics, we compared various parameters of microtubule dynamics in the temperature-sensitive mor1-1 mutant at its permissive and restrictive temperatures, 21°C and 31°C, respectively. Dynamic events were tracked in live cells expressing either GFP-tagged β-tubulin or the plus end tracking EB1. Microtubule growth and shrinkage velocities were both dramatically reduced in mor1-1 at 31°C and the incidence and duration of pause events increased. Interestingly, the association of EB1 with microtubule plus ends was reduced in mor1-1 whereas side wall binding increased, suggesting that MOR1 influences the association of EB1 with microtubules either by modulating microtubule plus end structure or by interacting with EB1. Although mor1-1 microtubules grew and shrank more slowly than wild-type microtubules at 21°C, the incidence of pause was not altered, suggesting that pause events, which occur more frequently at 31°C, have a major detrimental role in the spatial organization of cortical microtubules. Extensive increases in microtubule dynamics in wild-type cells when shifted from 21°C to 31°C underline the importance of careful temperature control in live cell imaging.
The Prevalence of Hepatitis C Virus Infection and Its Related Risk Factors Among the Rural Population of Fars Province, Southern Iran

Background: Hepatitis C virus (HCV) infection is a major blood-borne infection with silent epidemic, major global public health problem and diverse prevalence worldwide. Objectives: This study aimed to evaluate the prevalence of HCV infection and related risk factors in the general population of two villages, Farmashkan and Akbarabad, of the Kavar City in Fars Province, Iran. Patients and Methods: A 34-month cross-sectional study was performed on all people of the villages aged ≥ 7 years from July 2007 to April 2010. Demographic information and history of HCV-related risk factors were extracted from their medical records. For each participant, the serum anti-HCV IgG was assessed by the commercial enzyme-linked immunosorbent assay (ELISA) kits. Results: A total of 6095 participants (36.4% male and 65.6% female) with the mean age of 92 (7-95) and mean ± SD of 34.6 ± 17.3 years were included in this study. Fifteen persons (0.24%) were detected as HCV-positive and the highest prevalence was seen in age ≤ 12 years old (1%). A significant association was only detected between blood transfusion and HCV infection; therefore, those persons with history of blood transfusion had 15-fold higher risk for HCV seropositivity (odds ratio 15.54, 95% CI = 4.89-49.41). Conclusions: Our reported rate of HCV seropositivity is similar to the previous Iranian reports. However, future evaluations should be focused on the Polymerase Chain Reaction method for the detection of HCV and determining and evaluating of other related risk factors. Moreover, more attention should be paid to blood donors as a reservoir population of HCV.
Performance analysis of a ultra-compact low-power rectenna in paper substrate for RF energy harvesting

In this paper the experimental results of a compact low-power rectenna in paper substrate, designed to operate in the Wi-Fi band, are presented. The complete prototype, based on an annular slot antenna and a single-diode rectifier, features a weight of 1.5 grams and shows an RF-to-dc conversion efficiency in the design band of about 40 % for a −10 dBm available input power, of about 28 % at −15 dBm, and in the range [10, 22] % at −20 dBm, corresponding to an output DC voltage in the order of 320, 240 and 60 mV respectively. Additionally, the rectenna features an efficiency higher then 7 % in the whole band 1.8–2.7 dBm for a power density estimated around 3 µW/cm2.
Practices and knowing in transnational knowledge-intensive service provision

How do professionals at different locations within a firm collaborate to provide services across borders? This article addresses how knowledge-intensive service provisions are coordinated across borders, time zones and expertise. Empirical material from two engineering firms providing services to a global customer base are analysed, comprising over 100 interviews and over 20 days of observation. Concepts from practice theory are used, locating questions of knowledge in the realm of practical action. Findings describe how transnational services are enacted through prefigured and emergent practices. The problem of coordinating transnational practices is considered as a matter of balanced acting between these contrasting forms of work. This is explored in terms of the forms of knowledge that are in play – nuancing practical understanding into specific notions of know-how, know-what, know-who, know-why and know-where/when. Connecting this array of knowledge forms with balanced acting between prefigured and emergent practices extends theorizations of transnational knowledge-intensive firms, and casts new light on how the widespread problem of coordination can be addressed.
