In line or at odds with active ageing policies? Exploring patterns of retirement preferences in Europe
Authors: HOFÄCKER DIRK 
Published: June 2014

ABSTRACTFaced with demographic ageing, European policy makers since the mid-1990s have taken a turn from fostering early retirement to promoting longer working life by reducing early exit incentives and facilitating work continuation. However, it remains open whether these reforms are yet reflected in the retirement plans and preferences of future pensioners’ cohorts. Using most recent data on desired retirement ages from the fifth wave of the European Social Survey (2010/11 wave), this paper empirically investigates how far current policy reforms are in line with the retirement age preferences of older workers aged 45 and over. Results show that older workers approaching retirement ages still intend to retire before the politically envisioned age of 65, and in many cases also before nationally defined standard retirement ages. Despite visible progress in implementing active ageing measures, the challenge of motivating older workers to continue working until or even beyond retirement ages thus remains. At the same time, there are regime-specific problem groups that face difficulties in adjusting to the active ageing paradigm of longer working life. Especially in countries with little employment support, those with unstable work careers, employment interruptions and few financial resources are at a high risk of being crowded out from late career employment and thus from the possibility of ensuring a decent standard of living in old age.
Ross on Self and Others

Ross suggests a trilemma:(i)Innocent pleasure is good as an end.(ii)I have a prima facie duty to produce what is good as an end.(iii)I have no prima facie duty to produce innocent pleasure for myself.InThe Right and the Good, he denies (iii). InFoundations of Ethics, he denies (i). Neither of these solutions is satisfactory. One ought instead to deny (ii). I close by considering a similar trilemma concerning justice.

AbstractObjectiveIncreasing a parent’s ability to influence a child’s vegetable intake may require reducing the parent’s use of ineffective vegetable parenting practices. The present study was designed to understand the psychosocial influences on ineffective vegetable parenting practices.DesignA cross-sectional web-based survey was conducted to model use of ineffective vegetable parenting practices using validated scales from a Model of Goal Directed Vegetable Parenting Practices.SettingThe dependent variable was a composite ineffective vegetable parenting practices index. The independent variables included validated subscales of intention, habit, perceived barriers, desire, competence, autonomy, relatedness, attitudes, norms, perceived behavioural control and anticipated emotions. Models were analysed using block regression with backward deletion.SubjectsParents of 307 pre-school children (3–5 years old).ResultsVariables significantly positively related to ineffective vegetable parenting practices in order of relationship strength included habit of controlling vegetable practices (standardized β=0·349, P<0·0001) and desire (standardized β=0·117, P=0·025). Variables significantly negatively related to ineffective vegetable parenting practices in order of relationship strength included perceived behavioural control of negative parenting practices (standardized β=–0·215, P<0000), the habit of active child involvement in vegetable selection (standardized β=–0·142, P=0·008), anticipated negative parent emotional response to child vegetable refusal (standardized β=–0·133, P=0·009), autonomy (standardized β=–0·118, P=0.014), attitude about negative effects of vegetables (standardized β=–0·118, P=0·015) and descriptive norms (standardized β=–0·103, P=0·032). The model accounted for 40·5 % of the variance in use of ineffective vegetable parenting practices.ConclusionsThe present study is the first report of psychometrically tested scales to predict use of ineffective vegetable parenting practices. Innovative intervention procedures will need to be designed and tested to reduce ineffective vegetable parenting practices.

Published: June 2014

AbstractObjectiveTo investigate associations of self-perceived eating-related peer norms (called ‘subjective peer norms’) with adolescents’ healthy eating intentions and intake of healthy and unhealthy food.DesignCross-sectional data were collected in a large international survey.SettingTwo types of subjective peer norms were assessed: perceived peer encouragement of healthy eating and perceived peer discouragement of unhealthy eating. Outcome variables were healthy eating intentions, intake of healthy food (fruits and vegetables) and intake of unhealthy food (snacks and soft drinks).SubjectsOver 2500 European (pre-)adolescents aged between 10 and 17 years participated.ResultsSubjective peer norms were associated with all three outcome variables. While both perceived encouragement of healthy eating and perceived discouragement of unhealthy eating were related to intentions, only peer encouragement of healthy eating was related to intakes of both healthy and unhealthy food.ConclusionsSubjective peer norms play a role in adolescent eating behaviour and as such are an important target for health promotion. Addressing norms that encourage healthy eating may be more promising in changing behaviour than norms that discourage unhealthy eating.
Glassy states and super-relaxation in populations of coupled phase oscillators
Authors: Iatsenko D. , McClintock P.V.E. , Stefanovska A. 
Published: June 2014

AbstractLarge networks of coupled oscillators appear in many branches of science, so that the kinds of phenomena they exhibit are not only of intrinsic interest but also of very wide importance. In 1975, Kuramoto proposed an analytically tractable model to describe these systems, which has since been successfully applied in many contexts and remains a subject of intensive research. Some related problems, however, remain unclarified for decades, such as the existence and properties of the oscillator glass state. Here we present a detailed analysis of a very general form of the Kuramoto model. In particular, we find the conditions when it can exhibit glassy behaviour, which represents a kind of synchronous disorder in the present case. Furthermore, we discover a new and intriguing phenomenon that we refer to as super-relaxation where the oscillators feel no interaction at all while relaxing to incoherence. Our findings offer the possibility of creating glassy states and observing super-relaxation in real systems.

BackgroundOutbreaks of multidrug-resistant organisms have been linked to endoscope reprocessing lapses. Meticulous manual cleaning before high-level disinfection (HLD) is essential in reducing residual contamination that can interfere with HLD. Current reprocessing guidelines state that visual inspection is sufficient to confirm adequate cleaning.ObjectiveOur aim was to evaluate contamination of clinically used endoscopes, using visual inspection and rapid indicator tests before and after manual cleaning. A second objective was to determine which rapid indicator instruments and methods could be used for quality improvement initiatives in endoscope reprocessing.DesignClinical use study of endoscope reprocessing effectiveness.SettingTertiary care teaching hospital with an inpatient endoscopy center.MethodsResearchers sampled endoscopes used for gastrointestinal procedures before and after manual cleaning. The external surfaces and 1 channel of each endoscope were visually inspected and tested with rapid indicators to measure protein, blood, and adenosine triphosphate (ATP) contamination levels.ResultsMultiple components were sampled during 37 encounters with 12 unique endoscopes. All bedside-cleaned endoscopes had high levels of ATP and detectable blood or protein, whether or not any residue was visible. Although there was no visible residue on any endoscopes after manual cleaning, 82% had at least 1 positive rapid indicator test.ConclusionsRelying solely on visual inspection of endoscopes prior to HLD is insufficient to ensure reprocessing effectiveness. For quality assurance initiatives, tests of different endoscope components using more than 1 indicator may be necessary. Additional research is needed to validate specific monitoring protocols.
Much to Do about Carbapenem-Resistant Enterobacteriaceae: Why Supplementing Surveillance May Be the Key to Stopping Spread
Authors: Pfeiffer Christopher D. , Beldavs Zintars G. 
Published: June 2014

(See the article by Thaden et al, on pages 978–983.)It is critical to the future of public health to understand the burden of carbapenem-resistant Enterobacteriaceae (CRE) so that we can effectively target efforts to limit potential spread. The Centers for Disease Control and Prevention (CDC) classifies CRE as 1 of 3 “urgent” antibiotic resistance threats to public health because of the high mortality associated with CRE infection and its rapid dissemination in the United States.What is the current burden of CRE disease? We can glean a snapshot of the national epidemiology of CRE from the CDC’s national surveillance. Rapid geographic spread is evident in the CDC’s national map of CRE, which indicates that all but 3 states now have identified CRE. Incidence by facility type, procedure, device, and organism all have considerable variation, providing preliminary indications where future prevention efforts might best be focused. The 2013 CRE Vital Signs states that 3.9% of short-stay acute care hospitals and 17.8% of long-term acute care hospitals have identified cases of CRE infection among those with catheter-associated urinary tract infection (CAUTI) or central line–associated bloodstream infection (CLABSI). The CDC also reported that 10% of Klebsiella species in intensive care unit (ICU) CLABSIs, ICU CAUTIs, and surgical site infections after colon surgery or coronary artery bypass grafting in 2011 were carbapenem resistant. Although CRE have been reported in most states, it is increasingly clear that wide regional variation exists, from regions of hyperendemicity, such as parts of New York City, to regions apparently free of CRE, such as Maine.

BackgroundInterventions that prevent healthcare-associated infection should lead to fewer deaths and shorter hospital stays. Cleaning hands (with soap or alcohol) is an effective way to prevent the transmission of organisms, but rates of compliance with hand hygiene are sometimes disappointingly low. The National Hand Hygiene Initiative in Australia aimed to improve hand hygiene compliance among healthcare workers, with the goal of reducing rates of healthcare-associated infection.MethodsWe examined whether the introduction of the National Hand Hygiene Initiative was associated with a change in infection rates. Monthly infection rates for healthcare-associated Staphylococcus aureus bloodstream infections were examined in 38 Australian hospitals across 6 states. We used Poisson regression and examined 12 possible patterns of change, with the best fitting pattern chosen using the Akaike information criterion. Monthly bed-days were included to control for increased hospital use over time.ResultsThe National Hand Hygiene Initiative was associated with a reduction in infection rates in 4 of the 6 states studied. Two states showed an immediate reduction in rates of 17% and 28%, 2 states showed a linear decrease in rates of 8% and 11% per year, and 2 showed no change in infection rates.ConclusionsThe intervention was associated with reduced infection rates in most states. The failure in 2 states may have been because those states already had effective initiatives before the national initiative’s introduction or because infection rates were already low and could not be further reduced.

Published: June 2014

AbstractMotivation: MicroRNAs (miRNAs) are short single-stranded non-coding molecules that usually function as negative regulators to silence or suppress gene expression. Owning to the dynamic nature of miRNA and reduced microarray and sequencing costs, a growing number of researchers are now measuring high-dimensional miRNA expression data using repeated or multiple measures in which each individual has more than one sample collected and measured over time. However, the commonly used univariate association testing or the site-by-site (SBS) testing may underutilize the longitudinal feature of the data, leading to underpowered results and less biologically meaningful results.Results: We propose a penalized regression model incorporating grid search method (PGS), for analyzing associations of high-dimensional miRNA expression data with repeated measures. The development of this analytical framework was motivated by a real-world miRNA dataset. Comparisons between PGS and the SBS testing revealed that PGS provided smaller phenotype prediction errors and higher enrichment of phenotype-related biological pathways than the SBS testing. Our extensive simulations showed that PGS provided more accurate estimates and higher sensitivity than the SBS testing with comparable specificities.Availability and implementation : R source code for PGS algorithm, implementation example and simulation study are available for download at https://github.com/feizhe/PGS .Contact: y-zheng@northwestern.eduSupplementary information: Supplementary data are available at Bioinformatics online.

Abstract
Using S-adenosyl-methionine as the methyl donor, caffeic acid O-methyltransferase from sorghum (Sorghum bicolor; SbCOMT) methylates the 5-hydroxyl group of its preferred substrate, 5-hydroxyconiferaldehyde. In order to determine the mechanism of SbCOMT and understand the observed reduction in the lignin syringyl-to-guaiacyl ratio of three brown midrib12 mutants that carry COMT gene missense mutations, we determined the apo-form and S-adenosyl-methionine binary complex SbCOMT crystal structures and established the ternary complex structure with 5-hydroxyconiferaldehyde by molecular modeling. These structures revealed many features shared with monocot ryegrass (Lolium perenne) and dicot alfalfa (Medicago sativa) COMTs. SbCOMT steady-state kinetic and calorimetric data suggest a random bi-bi mechanism. Based on our structural, kinetic, and thermodynamic results, we propose that the observed reactivity hierarchy among 4,5-dihydroxy-3-methoxycinnamyl (and 3,4-dihydroxycinnamyl) aldehyde, alcohol, and acid substrates arises from the ability of the aldehyde to stabilize the anionic intermediate that results from deprotonation of the 5-hydroxyl group by histidine-267. Additionally, despite the presence of other phenylpropanoid substrates in vivo, sinapaldehyde is the preferential product, as demonstrated by its low K m for 5-hydroxyconiferaldehyde. Unlike its acid and alcohol substrates, the aldehydes exhibit product inhibition, and we propose that this is due to nonproductive binding of the S-cis-form of the aldehydes inhibiting productive binding of the S-trans-form. The S-cis-aldehydes most likely act only as inhibitors, because the high rotational energy barrier around the 2-propenyl bond prevents S-trans-conversion, unlike alcohol substrates, whose low 2-propenyl bond rotational energy barrier enables rapid S-cis/S-trans-interconversion.
European SMEs and the Brazilian market
Authors: Salvador Elisa , Pinot de Villechenon Florence , López Rizzo Humberto 
Published: June 2014

Purpose
– This paper aims to investigate the importance of networking for Italian and French small and medium-sized enterprises (SMEs) in Brazil. Business opportunities in Brazil have attracted a significant amount of interest in recent years. The country is moving towards market orientation, and it has recently experienced higher growth rates. Furthermore, upcoming events, such as the FIFA World Cup in 2014 and the 2016 Olympic Games in Rio de Janeiro, are attracting a significant amount of attention given the emergence of potential business opportunities in several sectors. Nevertheless, European companies wishing to enter the Brazilian market should address several constraints, including high barriers to entry, an extensive bureaucracy and a culture quite different from those in Europe. In this context, networking seems to be vital for success.

Design/methodology/approach
– The data were gathered through a survey undertaken between June and August 2012. After the questionnaire was prepared, each company either received and responded to the questionnaire by e-mail or participated in a telephone interview. The questionnaire included multiple choice questions, most of which used a 5-point Likert scale. Some open-ended questions were included to collect insights from respondents. Representatives of 21 Italian and 24 French SMEs agreed to participate in the survey. Respondents were typically company presidents, chief executive officers or export department managers with experience in the Brazilian market.

Findings
– The results highlight the importance of social networks for the SMEs interviewed. The establishment of social networks is pivotal for successful business activities in Brazil, as they can help entrants decipher and understand how society and business work. In Brazil, social networks are built through a path-dependent process that requires time, patience and perseverance, as well as an ability to overcome liabilities of sameness. In this regard, a networking process that encompasses specific activities linked to the peculiarities of Brazil is essential, even if it seems to be a second-best solution, as in the case of the QWERTY keyboard. This process, which is the main characteristic of social networking in Brazil, necessitates not only the use of the Internet and information and communications technologies but also face-to-face contacts for building reputation, legitimacy and trust.

Originality/value
– This paper extends the extant literature by investigating the importance of networking for Italian and French SMEs in Brazil. Brazil serves as an interesting and useful case that can deepen our knowledge about this aspect of international business. As highlighted by Jack et al. (2008) and Ruzzier et al. (2006), the knowledge and understanding of the networking process still suffers from several limitations despite the increased attention paid to this phenomenon.
Satisfaction with teaching and learning and the role of psychological need fulfillment
Authors: White Christopher , Fry Tim 
Published: June 2014

Purpose
– The purpose of this paper is to develop a model to assess participant satisfaction of a teaching and learning experience. Additionally, the way innate psychological needs influence the satisfaction formation process will be examined.

Design/methodology/approach
– A cross-sectional, quantitative approach was chosen and path analysis and t-tests were used to analyze the data.

Findings
– Satisfaction is formed by two related constructs, emotions and perception of quality, and together explained 53 percent of the variance in satisfaction. Higher levels of psychological need fulfillment were shown to positively influence emotions and quality perceptions and indirectly influence satisfaction judgements.

Practical implications
– These findings have relevance for education and training providers. First, they provide a comprehensive way for educationists to manage and measure satisfaction.

Originality/value
– Many teaching and learning evaluations are based on quality judgement and single measure of satisfaction. This study shows the important role positive and negative emotions play in determining satisfaction judgements. Additionally, and for the first time, the influence of different levels of psychological need fulfillment on satisfaction has been reported.
Where is the love?

Published: June 2014

Purpose– The purpose of this study is to explore polygamous program loyalty in hotel loyalty programs and the relationship between members’ behavioral loyalty and their perceptions of the program effectiveness.Design/methodology/approach– Descriptive statistics, discriminant analysis, ordinary least square regression and one-way ANOVA methods.Findings– This study suggests that the flexibility to purchase points in a loyalty program is significantly associated with the polygamous program loyalty. Members will stay in only one program if they perceive such flexibility. Although members tend to emphasize purchasing accommodation from the loyalty programs’ hotels, they do not necessarily advocate or pay price premiums for the brand. Compared with basic members, elite members exhibit higher levels of loyalty behaviors in general, but not in terms of paying price premiums.Research limitations/implications– The results suggest that how customers value a loyalty program can differentiate the number of membership(s) they have. Increasing the flexibility of point purchase in hotel loyalty programs encourages customers to stay in only one program. With a majority of the participants in the study being senior travelers, the results and implications should be generalized only in the senior market. A larger and more diverse sample is recommended for future research.Practical implications– If loyalty programs seek to keep members from joining other loyalty programs, they should increase members’ likelihood to achieve their expected benefits such as increased flexibility of point purchase. In addition, loyalty programs should encourage, recognize and incentivize members’ reciprocal behaviors based on the norm of reciprocity to build a reciprocal chain in loyalty programs. However, in seeking sustained loyal behavior, loyalty programs need to demonstrate value beyond transactional rewards.Originality/value– This paper explores the reason why customers join multiple loyalty programs (i.e. polygamous program loyalty) and identifies a broken reciprocity link in hotel loyalty programs. Many members primarily focus on the utilities of loyalty programs rather than contributing back to the program; therefore, the norm of reciprocity is suggested to improve loyalty program effectiveness.
