Mental health, marital intimacy and support in elderly caregivers of physically frail partners

The impact of caregiving and the role of psychosocial resources are examined in elderly spouses of the physically frail. Despite evidence from the literature, the strain of caring for older people with physical illnesses is less well recognised than that of caring for dementia sufferers. Similarly, although marriage is the prime location of care, the impact on the marital relationship is little studied. In this study elderly spouse caregivers were interviewed before and after their partner's attendance at a day hospital. Questionnaires were used to assess stressors, mood, general mental health and perceptions of strain, marital intimacy and social support. It was predicted that these caregivers would experience significantly poorer mental health than the general population, with low levels of marital intimacy and social support. The relationship between these variables was therefore explored using a longitudinal design. It was predicted that mental health would be significantly improved at the second meeting, principally predicted by the caregiver's satisfaction with the formal service and their perceptions of informal support and intimacy. Gender differences were explored and qualitative data presented. The results are discussed with reference to the implications for formal service provision and methodological issues
Genome-wide analysis reveals distinct patterns of epigenetic features in long non-coding RNA loci

A major fraction of the transcriptome of higher organisms comprised an extensive repertoire of long non-coding RNA (lncRNA) which express in a cell type and development stage-specific manner. While lncRNAs are a proven component of epigenetic gene expression modulation, epigenetic regulation of lncRNA itself remains poorly understood. Here we have analysed pan-genomic DNA methylation and histone modification marks (H3K4me3, H3K9me3, H3K27me3 and H3K36me3) associated with transcription start site (TSS) of lncRNA in four different cell types and three different tissue types representing various cellular stages. We observe that histone marks associated with active transcription H3K4me3 and H3K36me3 along with the repressive histone mark H3K27me3 have similar distribution pattern around TSS irrespective of cell types. Also, the density of these marks correlates well with expression of protein-coding and lncRNA genes. In contrast, the lncRNA genes harbour higher methylation density around TSS than protein-coding genes regardless of their expression status. Furthermore, we found that DNA methylation along with the other repressive histone mark H3K9me3 does not seem to play a role in lncRNA expression. Thus, our observation suggests that epigenetic regulation of lncRNA shares common features with mRNA except the role of DNA methylation which is markedly dissimilar.
Comparison of SCImago journal rank indicator with journal impact factor

The application of currently available sophisticated algorithms of citation analysis allows for the incorporation of the “quality” of citations in the evaluation of scientific journals. We sought to compare the newly introduced SCImago journal rank (SJR) indicator with the journal impact factor (IF). We retrieved relevant information from the official Web sites hosting the above indices and their source databases. The SJR indicator is an open‐access resource, while the journal IF requires paid subscription. The SJR indicator (based on Scopus data) lists considerably more journal titles published in a wider variety of countries and languages, than the journal IF (based on Web of Science data). Both indices divide citations to a journal by articles of the journal, during a specific time period. However, contrary to the journal IF, the SJR indicator attributes different weight to citations depending on the “prestige” of the citing journal without the influence of journal self‐citations; prestige is estimated with the application of the PageRank algorithm in the network of journals. In addition, the SJR indicator includes the total number of documents of a journal in the denominator of the relevant calculation, whereas the journal IF includes only “citable” articles (mainly original articles and reviews). A 3‐yr period is analyzed in both indices but with the use of different approaches. Regarding the top 100 journals in the 2006 journal IF ranking order, the median absolute change in their ranking position with the use of the SJR indicator is 32 (1st quartile: 12; 3rd quartile: 75). Although further validation is warranted, the novel SJR indicator poses as a serious alternative to the well‐established journal IF, mainly due to its openaccess nature, larger source database, and assessment of the quality of citations. —Falagas, M.

Alcohol Drinking, Smoking, Cannabis Use and Physical and Mental Health among Finnish University Students : A Longitudinal Study

9 of the female and 11.1% of the male first-year students, and 4.4% of the female and 10.8% of the male fifth-year students could be considered heavy drinkers. On the other hand, over two thirds of the first-year heavy drinkers decreased their alcohol consumption to the level of social drinking. No changes were noted in the frequency of drinking for intoxication between these two time points. The smoking among university students decreased significantly during the followup: the proportion of female non-smokers increased from 80% to 90% and that of male non-smokers from 78% to 84%. About half of the first-year heavy smokers continued similar smoking in their fifth year of studies. However, more than half of the first-year female and male smokers had quit smoking by the time they reached their fifth study year. Experimenting with cannabis increased significantly during the follow-up: in the first year, 88% of the students reported no experience with cannabis use, while in the fifth year the corresponding percentage was 78%. The maximum use (at least 5 times altogether) was reported by 70 (3%) first-year students and by 88 (5%) fifthyear students. Male students reported significantly more experimenting than female students. Nine percent of the students who expressed no use of cannabis in their first year reported at least some use in their fifth study year. The frequency of cannabis use also increased during the follow-up. The cannabis use was highly associated with both smoking and alcohol consumption. By and large, the university students' health status was good: over 85% of the students reported excellent or good health in both inquiries. Depression, tension and anxiety nevertheless increased significantly during the follow-up, as did also stress experiences. Alcohol consumption associated significantly with depression.
Complexity of Many Cells and Sum of Squares of Cell Complexities in Hyperplane Arrangements Too long ∗

Let H be a collection of n hyperplanes in d-space. We will assume that the planes are in general position, meaning that any k planes meet in a d− k-flat, if k = 1, . , d, and not at all if k > d.

When Do Secondary Markets Harm Firms

To investigate whether secondary markets aid or harm durable goods manufacturers, we build a dynamic model of durable goods oligopoly with transaction costs in the secondary market. Calibrating model parameters using data from the US automobile industry, we find the net effect of opening the secondary market is to decrease new car manufacturers' profits by 35 percent. Counterfactual scenarios in which the size of the used good stock decreases, such as when products become less durable, when the number of firms decreases, or when firms can commit to future production levels, increase the profitability of opening the secondary market.
TREATMENT RECOMMENDATION IN VIETNAMESE MEDICAL CONSULTATIONS

This study investigated the doctor’s recommendation of treatment to their adult patients in primary-care visits in the Vietnamese context. Data was gathered from 55 audio-recorded consultations at two public hospitals, and examined from a conversation-analytic perspective. We demonstrate that the participating doctors used two main approaches to treatment recommendation with their patients: general and detailed. In the latter case, the doctor recommended a treatment regime, sought the patient’s agreement, or offered choices regarding aspects of the treatment. Our overall contention is that, in the Vietnamese public hospital system, the doctor’s organisation of talk in the course of recommending treatment tends to be shaped by the institutional and cultural context in which it occurs, regardless of which type of treatment approach is being used.
Changing Capital Structure with Reinsurance : Wealth and Performance Effects

Existing research on capital structure and security issuance generally finds that when equity is undervalued, firms should issue debt and repurchase outstanding equity. However, the potential also exists for firms to enrich controlling shareholders by issuing undervalued equity. Within the insurance context, by exploiting their information advantage about their loss liabilities, insurers can execute a capital structure swap in relative opacity by using the proceeds from a seasoned equity offering to purchase reinsurance. We test this hypothesis by examining short-run and long-run stock returns of both insurers and non-insurers following SEOs. Results are consistent with expectations that post-SEO stock returns are significantly lower than the market and that insurer post-SEO stock returns are significantly greater than those of non-insurers.
Investigating the depletion effect: Self-control does not waiver in capuchin monkeys

The ego-depletion hypothesis states that self-control diminishes over time and with exertion. However, there is mixed evidence among human adult and comparative studies as to whether such depletion occurs. It is an important issue, given that evidence for or against this hypothesis could have implications for remediation efforts with individuals who show high impulsivity and low self-control. In a study of potential depletion effects on selfcontrol, capuchin monkeys were presented with two consecutive self-control tasks back-to-back within sessions. Monkeys first completed the accumulation task, in which they were presented with food items one-by-one until the subject retrieved and ate the accumulating items, at which point no more food would be delivered. This required continual inhibition of food retrieval in the face of an increasingly desirable reward. Then, monkeys completed a food exchange task with exchange combinations that either decreased or increased in food quality. Self-control was required in foregoing eating an immediately available food for a potentially better reward later in the trial. Individual differences in accumulation performance were observed, but no depletion effects were seen in the monkeys’ exchange performance. Next, monkeys were presented with task order counterbalanced across individuals. No order effects were observed in the monkeys’ performance on either self-control task. Monkeys’ exchange performance was not significantly correlated with accumulation performance in either experiment. These results indicate no depletion effects and that these tasks may not be related in terms of underlying mechanisms that support self-control performance, even though at face value both require inhibition of eating available food.
Neuroimaging in Parkinson’s Disease

Neuroimaging has provided insight into the pathophysiology and natural history of Parkinson’s disease (PD) and has emerged as a tool to monitor disease progression and to assess new potentially neuroprotective or neurorestorative therapies for PD. Diverse imaging methods have been successfully applied to neurological disorders. While technology like functional magnetic resonance imaging or magnetic resonance spectroscopy has been especially useful in assessing stroke, multiple sclerosis and epilepsy (1–3), in vivo neuroreceptor imaging using single photon emission tomography (SPECT) and positron emission tomogrpahy (PET) have so far been most valuable in assessing PD. SPECT and PET use specific radioactively labeled ligands to neurochemically tag or mark normal or abnormal brain chemistry. Recent advances in radiopharmaceutical development, imaging detector technologies, and image analysis software have expanded and accelerated the role of imaging in clinical research in PD, in general, and neurotherapeutics, in particular. In this overview we will focus on developments in neuroreceptor imaging in PD.
Integration and continuity of Care in health care network models for frail older adults

A detailed review was conducted of the literature on models evaluating the effectiveness of integrated and coordinated care networks for the older population. The search made use of the following bibliographic databases: Pubmed, The Cochrane Library, LILACS, Web of Science, Scopus and SciELO. Twelve articles on five different models were included for discussion. Analysis of the literature showed that the services provided were based on primary care, including services within the home. Service users relied on the integration of primary and hospital care, day centers and in-home and social services. Care plans and case management were key elements in care continuity. This approach was shown to be effective in the studies, reducing the need for hospital care, which resulted in savings for the system. There was reduced prevalence of functional loss and improved satisfaction and quality of life on the part of service users and their families. The analysis reinforced the need for change in the approach to health care for older adults and the integration and coordination of services is an efficient way of initiating this change.
p38 Activation Is Required Upstream of Potassium Current Enhancement and Caspase Cleavage in Thiol Oxidant-Induced Neuronal Apoptosis

Oxidant-induced neuronal apoptosis has been shown to involve potassium and zinc dysregulation, energetic dysfunction, activation of stress-related kinases, and caspase cleavage. The temporal ordering and interdependence of these events was investigated in primary neuronal cultures exposed to the sulfhydryl oxidizing agent 2,2′-dithiodipyridine (DTDP), a compound that induces the intracellular release of zinc. We previously observed that tetraethylammonium (TEA), high extracellular potassium, or cysteine protease inhibitors block apoptosis induced by DTDP. We now report that both p38 and extracellular signal-regulated kinase phosphorylation are evident in neuronal cultures within 2 hr of a brief exposure to 100 μm DTDP. However, only p38 inhibition is capable of blocking oxidant-induced toxicity. Cyclohexamide or actinomycin D does not attenuate DTDP-induced cell death, suggesting that posttranslational modification of existing targets, rather than transcriptional activation, is responsible for the deleterious effects of p38. Indeed, an early robust increase in TEA-sensitive potassium channel currents induced by DTDP is attenuated by p38 inhibition but not by caspase inhibition. Moreover, we found that activation of p38 is required for caspase 3 and 9 cleavage, suggesting that potassium currents enhancement is required for caspase activation. Finally, we observed that DTDP toxicity could be blocked with niacinamide or benzamide, inhibitors of poly (ADP-ribose) synthetase. Based on these findings, we conclude that oxidation of sulfhydryl groups on intracellular targets results in intracellular zinc release, p38 phosphorylation, enhancement of potassium currents, caspase cleavage, energetic dysfunction, and translationally independent apoptotic cell death.
CAQDAS: a supplementary tool for qualitative market research

Purpose – The aims of the paper are twofold: to assess the usage of Computer Assisted Qualitative Data Analysis (CAQDAS) in the UK market research industry; and to evaluate the use of CAQDAS as a supplement to paper‐coding in market research.Design/methodology/approach – CAQDAS usage was assessed by a questionnaire, sent to a sample of 400 UK market researchers. The second part of the research is a case study of a research experiment. The authors conducted focus group research into online grocery shopping, supplementing a paper‐coding‐based analysis with a further analysis based on computer coding.Findings – Usage of CAQDAS in commercial market research is very low at only 9 percent. The research suggests that CAQDAS can be a useful supplement to traditional methods. Using computer software, the paper was able to mine the data for more detail; clearly identify minority views; and produce a useful resource for future research.Research limitations/implications – The survey response rate was 38 percent, but .
On the cohomology of torus manifolds

A torus manifold is an even-dimensional manifold acted on by a half-dimensional torus with non-empty fixed point set and some additional orie ntation data. It may be considered as a far-reaching generalisation of toric manifolds from algebraic geometry. The orbit space of a torus manifold has a rich combinatorial structure, e.g., it is a manifold with corners provided that the action is locally standard. Here we investigate relationships between the cohomological properties of torus manifolds and the combinatorics of their orbit quotients. We show that the cohomology ring of a torus manifold is generated by two-dimensional classes if and only if the quotient is a homology polytope. In this case we retrieve the familiar picture from toric geo metry: the equivariant cohomology is the face ring of the nerve simplicial complex and the ordinary cohomology is obtained by factoring out certain linear forms. In a more general situation, we show that the odd-degree cohomology of a torus manifold vanishes if and only if the orbit space is face-acyclic. Although the cohomology is no longer generated in degree two under these circumstances, the equivariant cohomology is still isomorphic to the face ring of an appropriate simplicial poset.

Cheating in Academia: The Relevance of Social Factors

We implemented an online anonymous survey targeted to current and former university students, where the interviewed are asked to indicate whether and to what extent they cheated during written exams. We want to learn if cheating is widespread, and if it correlates with social factors such as the level of trust in others, the beliefs about the peers’ dishonesty and perceived level of opportunism in the society. We find that 61% of the respondents report to have cheated once or more. Cheaters are more likely to report that their classmates and friends cheated, and that in general people can be trusted. In contrast, being aware of the sanction, earning top grades and thinking that people are willing to take advantage of others is negatively correlated with self-reported cheating. There is evidence of two different cheating styles: “social cheaters”, who self-report mostly that they have violated the rules interacting with others; “individualistic” cheaters, who self-report mostly that they have used prohibited materials. Only social cheaters seem affected by social factors: they exhibit higher levels of trust and lower levels of perceived opportunism compared to individualistic cheaters, while no differences between the two groups are found when looking at other dimensions.
Map updating in dynamic environments

While building maps when robot poses are known is a tractable problem requiring limited computational complexity, the simultaneous estimation of the trajectory and the map of the environment (known as SLAM) is much more complex and requires many computational resources. Moreover, SLAM is generally peformed in environments that do not vary over time (called static environments), whereas real applications commonly require navigation services in changing environments (called dynamic environments). Many real robotic applications require updated maps of the environment that vary over time, starting from a given known initial condition. In this context classical SLAM approaches are generally not directly applicable: such approaches only apply in static environments or in dynamic environments where it is possible to model the environment dynamics. We are interested here in long-term mapping operativity in presence of variations in the map, as in the case of robotic applications in logistic spaces, where rovers have to track the presence of goods in given areas. In this paper we propose a methodology that is able to detect variations in the environment, generate a local map containing only the persistent variations and finally merge the local map with the global one used for localization.

Maximum-principle-satisfying High Order Finite Volume Weighted Essentially Nonoscillatory Schemes for Convection-diffusion Equations

To easily generalize the maximum-principle-satisfying schemes for scalar conservation laws in [X. Zhang and C. -W. Shu, J. Comput. Phys., 229 (2010), pp. 3091-3120] to convection diffusion equations, we propose a nonconventional high order finite volume weighted essentially nonoscillatory (WENO) scheme which can be proved maximum-principle-satisfying. Two-dimensional extensions are straightforward. We also show that the same idea can be used to construct high order schemes preserving the maximum principle for two-dimensional incompressible Navier-Stokes equations in the vorticity stream-function formulation. Numerical tests for the fifth order WENO schemes are reported.
