Anxiety following cardiac surgery – an important aspect of health status assessment

Background. Patient-reported outcomes (Pros), including psychological factors, have become an important aspect of both health research and clinical practice. Patients who have undergone cardiac surgery can constitute a large subgroup of the patients of a family physician. Postoperative distress has been observed in up to 40% of patients. Objectives. the study aimed to evaluate anxiety levels among patients who had undergone cardiac surgery, and to explore the correlations between anxiety and depression and subjective health status. Material and methods. the research group consisted of 70 patients (48 men, mean age: 65.9 years; ± 8.5). the study was conducted during consultations three months after surgery. the Hospital anxiety and depression Scale (HadS), including question regarding suicidal thoughts, was used. a four-point likert scale was used to evaluate subjective effectiveness of the surgery and the Visual analogue Scale (VaS) was used to assess subjective health status. Results. an increased level of anxiety was observed in 23 patients (32.9%), and depression was seen in 12 (17.1%). 13 patients (18.6%) indicated that they had had suicidal thoughts. Patients with suicidal ideation had significantly higher level of anxiety. Significant positive correlations were noted between levels of anxiety and depression. anxiety level correlated negatively with subjective health status and assessment of surgery effectiveness. no significant connections were observed between level of anxiety and sex, age, or the type of surgery. Conclusions. 1. increased levels of anxiety were observed in a significant percentage of patients who had undergone cardiac surgery. 2. increased anxiety level is concomitant with depression, suicidal thoughts, and lower subjective health status assessment. 3. Health status assessment following cardiac surgery should also include the evaluation of mental health.
Pengaruh Mikoriza dan Pupuk NPK terhadap Pertumbuhan dan Produksi Jambu Mete Muda

Penelitian pengaruh fungi mikoriza asbuskula (FMA) dan pupuk NPK pada pertumbuhan dan produksi tanaman jambu mete muda dilaksanakan di KP. Cikampek, Jawa Barat dari bulan Januari sampai Desember 2011. Rancangan percobaan yang digunakan adalah acak kelompok, terdiri dari dua faktor, yang diulang 4 kali dengan ukuran plot 4 tanaman/perlakuan. Faktor I adalah aplikasi FMA, yaitu tanpa FMA dan aplikasi 12 kaplet FMA/tanaman. Faktor II adalah pupuk NPK (g/tan.) yang terdiri dari: (a) dosis pupuk NPK rekomendasi (100 g N, 80 g P 2 O 5 , 100 g K 2 O/tan.), (b) 3/4 dosis pupuk NPK rekomendasi, dan (c) 1/2 dosis pupuk NPK rekomendasi. Parameter pengamatan meliputi penambahan jumlah daun, tinggi tanaman, diameter cabang, lilit batang utama, lebar kanopi, panjang cabang, jumlah cabang tersier, jumlah tandan bunga, jumlah buah per tandan, dan jumlah gelondong per pohon. Hasil penelitian menunjukkan bahwa penurunan dosis pemupukan NPK sampai 50% dari dosis rekomendasi yang disertai dengan pemberian mikoriza (FMA) tidak mengakibatkan penurunan pertumbuhan dan produksi jambu mete varietas BO2 hasil grafting. Sebagai implikasi, adanya respon positif pada pertumbuhan dan produksi jambu mete dapat dijadikan petunjuk bahwa penggunaan mikoriza mampu meningkatkan efisiensi penggunaan pupuk NPK. Effect o f Mycorrhizal a nd N PK Fertilizer o n Young Cashew Growth a nd Production ABSTRACT A study of the application of arbuscular mycorrhiza fungi (AMF) and reduction of NPK fertilizer rates was carried out on grafted young cashew trees grown at Cikampek Research Station , West Java , from January to December 2011. Experimetal design used was a random ized block design , consisting of two factors, repeated 4 times with plot size of 4 plant s . The first f actor was application of AM F , consisting of without AM F and with inoculation of 12 AMF caplets/plant. The second f actor was a pplication of NPK fertilizer , c onsist ing of : ( a) Full recommend ed of NPK fertilizer rates (100 g N, 80 g P 2 O 5 , 100 g K 2 O/ plant .), (b ) 3/4 recommend ed NPK fertilizer rate, and ( c) 1/2 recommend ed NPK fertilizer rate . Parameters observ ed include d the increase of number of leave, plant height, diameter s of branch, main girth and canopy, branch length, number of tertiary branches, number of bunches of flowers, the number of fruits per bunch, and the number of nuts per tree. R esults showed that the reduction of NPK fertilizer application upto 50% of recommended fertilizer rates combined with the application of AMF on the young cashew trees (2.5 years old) did not result in any reduction of plant growth measured significantly. As an amplication, the application of micorhizal fungus is likely able to increase efficiency of fertilizer use to the crop indicated by comparable growth of the treated ones .
ARBOREOUS SPECIES POPULATION IN A TOPOGRAPHIC GRADIENT OF MIXED OMBROPHILOUS FOREST IN RIO GRANDE DO SUL

Abstract This study was part of the Long Term Ecological Project (PELD) conducted in the Sao Francisco de Paula National Forest, RS where Mixed Ombrophilous Forest is predominant. The aim was to identify distribution of arboreous species depending on different soil conditions occurring in the low, medium and upper slopes of the studied area. 180 sample units of 100 m 2 distributed along the topographical gradient were installed, with identification of the totality of arboreous species with 3 cm ≤ CBH < 30 cm and height exceeding 1.30 meters. In addition, thirteen environmental variables were collected in each sub-unit. The Canonical Correspondence Analysis model (CCA) indicated that only the slope, the topographic position, the stoniness and the soil color (up to 50 cm in depth) were the variables that best distinguished the sample groups of the slope environments. Out of the 53 species included in the model, ten species showed best correlations with the typical environments of upper slopes and 12 species were most characteristics of the lower positions, while the remaining resulted well adapted to different hillside topographic conditions. Environmental preferences of the species could be considered in silvicultural and recuperation programs applied to hillside environments of the region. Keywords : Araucarian Forest; species distribution pattern, edaphic characteristics; canonical correspondence analysis. Resumo Ocupacao de especies arboreas em um gradiente topografico na Floresta Ombrofila Mista no Rio Grande do Sul . O presente estudo foi parte do Projeto Ecologico de Longa Duracao (PELD), realizado na Floresta Nacional de Sao Francisco de Paula, RS, onde predomina a Floresta Ombrofila Mista. O objetivo foi identificar relacoes de distribuicao das especies arboreas em diferentes condicoes edaficas que ocorrem em posicoes inferiores, medias e superiores em encostas na area de estudo.

O modelo de Analise de Correspondencia Canonica (ACC) indicou que a variacao na declividade, na posicao topografica, na pedregosidade e na cor dos solos (na profundidade de ate 50 cm) foram as variaveis que melhor distinguiram os grupos de parcelas que caracterizaram os ambientes das encostas. Das 53 especies inseridas no modelo, dez especies demonstraram maiores correlacoes com os ambientes tipicos das encostas superiores e 12 especies foram mais caracteristicas das posicoes inferiores, enquanto que as demais apresentaram ampla adaptacao as diferentes posicoes das encostas. As preferencias ambientais das especies poderiam ser consideradas em programas silviculturais e de recuperacao nos ambientes de encostas na regiao. Palavras-chave : Floresta com Araucaria; padrao de distribuicao de especies; caracteristicas edaficas; analise de correspondencia canonica.
Cuckoo inspired algorithms for feature selection in heart disease prediction

Heart disease is a predominant killer disease in various nations around the globe. However, this is because the default medical diagnostic techniques are not affordable by common people. This inspires many researchers to rescue the situation by using soft computing and machine learning approaches to bring a halt to the situation. These approaches use the medical data of the patients to predict the presence of the disease or not. Although, most of these data contains some redundant and irrelevant features that need to be discarded to enhance the prediction accuracy. As such, feature selection has become necessary to enhance prediction accuracy and reduce the number of features. In this study, two different but related cuckoo inspired algorithms, cuckoo search algorithm (CSA) and cuckoo optimization algorithm (COA), are proposed for feature selection on some heart disease datasets. Both the algorithms used the general filter method during subset generation. The obtained results showed that CSA performed better than COA both concerning fewer number of features as well as prediction accuracy on all the datasets. Finally, comparison with the state of the art approaches revealed that CSA also performed better on all the datasets.
Regional climate model applications on sub-regional scales over the Indian monsoon region: The role of domain size on downscaling uncertainty

Many countries and provinces requiring these assessments are as small as 200,000 km 2 in size, significantly smaller than an ideal domain needed for successful applications of one-way nested regional climate models. Therefore assessments on sub-regional scales (e.g., river basins) are generally carried out using climate change simulations performed for relatively larger regions. Here we show that the seasonal mean hydrological cycle and the day-to-day precipitation variations of a sub-region within the model domain are sensitive to the domain size, even though the large scale circulation features over the region are largely insensitive. On seasonal timescales, the relatively smaller domains intensify the hydrological cycle by increasing the net transport of moisture into the study region and thereby enhancing the precipitation and local recycling of moisture. On daily timescales, the simulations run over smaller domains produce higher number of moderate precipitation days in the sub-region relative to the corresponding larger domain simulations. An assessment of daily variations of water vapor and the vertical velocity within the sub-region indicates that the smaller domains may favor more frequent moderate uplifting and subsequent precipitation in the region. The results remained largely insensitive to the horizontal resolution of the model, indicating the robustness of the domain size influence on the regional model solutions. These domain size dependent precipitation characteristics have the potential to add one more level of uncertainty to the downscaled projections. Citation: Bhaskaran, B. , A. Ramachandran, R.

Aggregation of pelagic Munida gregaria (Fabricius) (Decapoda, Anomura) by coastal fronts and internal waves

Aerial photographic surveys were used to study the distribution and abundance of the near- surface shoaling juvenile phase of the galatheid crab Munida gregaria in southeastern N.Z. continen­ tal shelf waters. On numerous occasions shoals were concentrated into aggregations many metres to a few kilometres long at river plume and headland fronts, and in mid-shelf internal waves. Laboratory experiments established that M. gregaria juveniles showed strong positive phototaxis and that they could sustain swimming speeds of = 16 cm s _ '. Field experiments showed that when M. gregaria were displaced to deeper waters, their response was to swim back towards the surface. These results suggest that juveniles swept into convergent zones would resist downward displacement. Since convergent zones occur at coastal front and internal wave sites this mechanism could explain the aggregations of shoals observed and photographed from the air. This mechanism is discussed in relation to literature on physical processes at such sites and to studies of plankton distribution and behaviour.
Vertical and horizontal integration, unbundling and quality of service in public utilities. A literature review

This work is aimed to present a literature review on the subject of economic evaluation of processes of vertical and horizontal integration in public utilities. First of all, the definition of economies of scope and the different methods of evaluation are illustrated. Subsequently, the problem of integration and the implementation of unbundling policies (business separation) is presented for different categories of utilities (energy, telecommunications, water, multiutilities). For some of them, the empirical literature is quite rich. A relevant number of contributions, in fact, cover the issue of costs generated by vertical integration in electricity, and the empirical results are quite consistent in confirming the presence of important synergies of integration. Other categories of public utilities, however, are less involved in empirical investigation (e.g. the gas industry). Finally, the problem of service quality is developed by examining the indicators used in each industry and then the issue is linked to the problem of integration. To date, empirical studies on economies of integration rarely involve quality measures, while the importance of such an element in terms of services delivered to consumers suggests that it can be an interesting point to be considered in future research.
Ground-based astrometry calibrated by Gaia DR1: new perspectives in asteroid orbit determination

The Gaia Data Release 1 (GDR1) is a first, important step on the path of evolution of astrometric accuracy towards a much improved situation. Although asteroids are not present in GDR1, this intermediate release already impacts asteroid astrometry. Our goal is to investigate how the GDR1 can change the approach to a few typical problems, including the determination of orbits from short-arc astrometry, the exploitation of stellar occultations, and the impact risk assessment. We employ optimised asteroid orbit determination tools, and study the resulting orbit accuracy and post-fit residuals. For this goal, we use selected ground-based asteroid astrometry, and occultation events observed in the past. All measurements are calibrated by using GDR1 stars. We show that, by adopting GDR1, very short measurement arcs can already provide interesting orbital solutions, capable of correctly identifying Near Earth Asteroids (NEAs) and providing a much more accurate risk rating. We also demonstrate that occultations, previously used to derive asteroid size and shapes, now reach a new level of accuracy at which they can be fruitfully used to obtain astrometry at the level of accuracy of Gaia star positions.
Heterogeneity in Returns to Wealth and the Measurement of Wealth Inequality

Lacking a long time series on the assets of the very wealthy, Saez and Zucman (2015) use US tax records to obtain estimates of wealth holdings by capitalizing asset income from tax returns. They document marked upward trends in wealth concentration. We use data on tax returns and actual wealth holdings from tax records for the whole Norwegian population to test the robustness of the methodology. We document that measures of wealth based on the capitalization approach can lead to misleading conclusions about the level and the dynamics of wealth inequality if returns are heterogeneous and even moderately correlated with wealth.

The College Football Gambling Market An Empirical Approach

This study tests the efficiency of the college football gambling market and whether the market allows for profitable wagering. Operating upon the theoretical framework that, at any given time, prices fully reflect all information available in a particular market, I test for the existence of residual information that is not currently incorporated into the market, thus rendering it inefficient. This project expands upon several previous studies performed on sports betting – most notably that of Zuber, Gandar, and Bowers (1985), which examined the gambling market efficiency for National Football League games. The findings prove to be consistent with the conclusions reached in these prior analyses, which suggest that speculative inefficiencies exist within the market.
Self-Compassion as a Mediator between Maladaptive Perfectionism and Anxiety in College Students

The purpose of the following study is to investigate whether self-compassion is a mechanism/process underlying the connection between maladaptive perfectionism and anxiety. Therefore, it was hypothesised that self compassion would mediate this maladaptive perfectionism anxiety association which has been extensively reported throughout existing literature. Seventy-nine college students completed a set of four questionnaires: The Almost Perfect Scale-Revised (APS-R); The Self-Compassion Scale (SCS); The Beck Anxiety Inventory (BAI); and The Penn State Worry Questionnaire (PSWQ). Preliminary correlations confirmed that each of these variables were strongly and significantly correlated with one another. Subsequently, two mediation analyses were run, producing both a full and partial mediation. The full mediation was a product of somatic anxiety set as the outcome variable, whereas the partial mediation was consequence to cognitive anxiety thereafter replacing the previous. Findings suggest that maladaptive perfectionism possibly inhibits an individual from engaging in self compassionate thoughts and emotions, rendering the individual susceptible to symptoms of anxiety. Aside from the pronounced implications relevant to the college student population, reinforcing evidence that self compassion is applicable to the therapeutic setting is visible in that promoting self-compassion may assist clinical practices in reducing negative impacts of self criticism, which have been reported to obstruct recovery outcomes in certain individuals.
Teaching creole-speaking children: Issues, concerns and resolutions for the classroom

There are now significant numbers of children who speak a language other than English when they enter the formal school system in Australia. Many of these children come from a language background that is entirely different from the school language. Many Indigenous children, however, come from creole-speaking backgrounds where their home language may share features with the school language whilst remaining substantially different in other ways. What often makes this situation more challenging is the tendency to view creole, rather than as a different language, as a kind of deficient version of the standard language. Children entering the school system with a creole thus often encounter considerable difficulties. In addition, teachers who are not trained in teaching creole-speaking children may not recognise these difficulties. This paper explores some of these issues in the Australian context with reference to home languages such as Kriol and Torres Strait Creole (TSC) as well as minority dialects such as Australian Aboriginal English (AAE), and discusses possible resolutions.
Galaxy and mass assembly (GAMA): A deeper view of the mass, metallicity and SFR relationships

A full appreciation of the role played by gas metallicity (Z), star formation rate (SFR) and stellar mass (M*) is fundamental to understanding how galaxies form and evolve. The connections between these three parameters at different redshifts significantly affect galaxy evolution, and thus provide important constraints for galaxy evolution models. Using data from the Sloan Digital Sky Survey–Data Release 7 (SDSS–DR7) and the Galaxy and Mass Assembly (GAMA) surveys, we study the relationships and dependences between SFR, Z and M*, as well as the Fundamental Plane for star-forming galaxies. We combine both surveys using volume-limited samples up to a redshift of z ≈ 0.36. The GAMA and SDSS surveys complement each other when analysing the relationships between SFR, M* and Z. We present evidence for SFR and metallicity evolution to z ∼ 0.2. We study the dependences between SFR, M*, Z and specific SFR (SSFR) on the M*–Z, M*–SFR, M*–SSFR, Z–SFR and Z–SSFR relations, finding strong correlations between all. Based on those dependences, we propose a simple model that allows us to explain the different behaviour observed between low- and high-mass galaxies. Finally, our analysis allows us to confirm the existence of a Fundamental Plane, for which M* = f(Z, SFR) in star-forming galaxies.
Macroeconomic Effects of Delayed Capital Liquidation∗

This paper studies macroeconomic effects of financial shocks through the lens of delayed capital liquidation and reallocation among firms. I develop a model in which firms face idiosyncratic productivity risks, financial constraints, and random liquidation costs. Liquidation costs generate an option value of staying and a liquidation delay for unproductive firms. A novel feature arising from the delay is that unproductive firms have a higher debt-to-asset ratio than productive ones. I find that adverse financial shocks that tighten financial constraints can raise the option value. The financial shocks also have general equilibrium effects that further raise the option value and delay capital liquidation. Capital is thus persistently misallocated, leading to a long-lasting economic contraction. Using U.S. data from 1971-2015, I show that financial shocks can explain almost 67% of the variation in the capital liquidation-to-expenditures ratio and 72% of the variation in output.
The Effect of Preoperative Exposure on Spouse Anxiety in the I.C.U.

THE EFFECT OF PREOPERATIVE EXPOSURE ON SPOUSE ANXIETY IN THE I.C. U. By Carol J . Gates The purpose of this investigation was to answer the question: What is the effect of preoperative exposure of the intensive care unit (I.C.U.) on anxiety levels of spouses of open heart patients? A pretest-posttest experimental design was used to analyze data collected on 50 spouses of open heart patients. The subjects were randomly assigned to either experimental or control groups. State and trait anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory (1983). The experimental group received preoperative I.C. U. exposure in the format of a videotape the evening of surgery and the control group received routine preoperative preparation. T-test, chi-square, Pearson correlation coefficient, and analysis of covariance were used to analyze the data. Posttest anxiety levels of the experimental group were lower than the control group but not at a statistically significant level. There was a positive correlation between trait and state anxieties and
