A Proposed Framework on Turnover Intention among Nursing Home Nurses

The majority of studies to date have focused on the job demands that influence nurses in hospital setting; with the nurses working in nursing home is being less explored. Failure to meet the demand in work may give negative impact for employees such as job stress and burnout, which can lead to turnover intention. Burnout has been identified as mediating variable in the relationship between job demands and turnover intention. This paper is aimed to examine the literature on the relationship between job demands and turnover intention. The literature reviews shows that there will be a positive relationship between job demands and turnover intention and there is a mediation effect of burnout through indirect relationship between job demands and turnover intention. Social supports from family, resident and supervisor are suggested to moderate the relationship between job demand and turnover intention. The strength of relationship between job demand and turnover intention depend on the mediation effect of burnout and moderating effect of social support. The findings of this study are expected to help private nursing home and related industry in development of the policy to improve the quality of human resources specifically among nursing staff.
Comparisons between Australian consumers' and industry experts' perceptions of ideal wine and cheese combinations

Background and Aims: Despite being a common food and beverage combination today, few scientific studies have examined ideal wine and cheese matches. The current study was designed to have Australian consumers evaluate wine and cheese combinations suggested by industry experts. Methods and Results: Under controlled conditions, 46 wine and cheese consumers examined the ‘ideal’ pairings of eight different cheese and wine styles, using a structured, 12-cm ‘just right’ line scale. The consumers agreed with the experts about six of the eight combinations. Red table wine was marginally more versatile than white table wine for cheese pairings. Cheddar and Gruyere were the most versatile cheeses while a white mould and blue mould were dominant over the wines. The Gewurztraminer and Sangiovese wines were most complementary to the cheeses but the Sauvignon Blanc and white dessert wine were the most difficult to match. Conclusions: These scientific results confirm some of the anecdotal beliefs held regarding the art of wine and food matching. Significance of the Study: The findings will enhance wine and food service professionals' knowledge of how wine and food sensory elements interact and transform one another, promoting better gastronomic experiences for consumers.

The Study of Community Periodontal Index of Treatment Needs

Materials and Methods: This study was a case-control study . The case group comprised 23 male, with confirmed COPD. The control group consisted of 33 healthy individuals. Both case and control groups, referred to specialized and sub-specialized clinic of the Ardabil Medical University and were selected according to our inclusion / exclusion criteria. The pulmonologist made the diagnosis of respiratory and non–respiratory disease. A questionnaire was recorded with the following key data: patient's age, gender, place of residence, their history of smoking, results of pulmonary function test, MMRC, CAT and exacerbations rate. Data regarding the frequency of dental visits, oral hygiene care and the results of dental examinations were recorded in a dental questionnaire based on Community Periodontal Index of Treatment Needs (CPITN). Data was also analyzed with descriptive statistics, Chi Square, Fisher, Monte Carlo tests and analysis of variance (ANOVA) using SPSS16 software.
Pets, touch, and COVID-19: health benefits from non-human touch through times of stress

During times of social isolation, such as the global COVID-19 pandemic, the social distancing mantras that have been integral to COVID-19 responses position close human-to-human contact, including physical touch, as life threatening. Touch is commonly an overlooked sense, yet studies have shown that touch deprivation reduces survival rates of pre-term babies and contributes to stunted mental and emotional development in institutionalized orphaned humans. For people who experience less social contact, touch deprivation may impact on quality of life. This article explores the notion that human to non-human contact, such as that between animal guardians and their pets, may assist in promoting health and wellbeing when human contact is limited. Use is made of a qualitative research project interviewing people on the role of their pets in creating health. 90% of participants (n = 29/32) identified touch as core to this intersection. Inductive touch themes identified include comfort, relaxation and reciprocity, pointing to the impacts but also the mechanisms by which cross-species touch can create human wellbeing – a relational resource that may counter COVID-19 touch deprivation engendered by prohibition of human-human contact. With over half of the world’s population having pets, these relationships may be one of our greatest health-promoting resources at this time. JEL Classification: H51; I1; I3
A Study on Surgical Management of Distal Tibial Fractures by Using Minimally Invasive Technique of Percutaneous Plate Osteosynthesis with Locking Compression Plate

Introduction: Tibia is the major weight bearing bone of the leg. It is the one of the commonest bone to be fractured. In an average population there are about 53 tibial fractures per 1 lakh population per year, out of which 70% are distal tibial fractures. For the past decade, plating using fracture reduction has been successful in treating complex fractures of the lower extremity especially distal tibia. Minimally invasive percutaneous plating will restore limb alignment and yield successful clinical outcomes for high-energy fractures of the distal tibia. Aim & Objectives: 1. To study Distal Tibial Fractures including Pilon Fractures in adults. 2. To assess time required for fracture union. 3. To evaluate functional outcome of the surgery and compare with those in literature. 4. To study complications of surgery. Methodology: The present study was conducted from 1st September 2016 to 1 st Sptember 2017 at the Department of Orthopaedics, Varun Arjun Medical College, Shahjahanpur, During this period 14 patients of distal one third tibia fractures were treated surgically. Results: The age of the patients ranged from 18 to 65 years with the fracture being most common in the 3rd and 4th decade and an average age of 39 years. Out of 14 patients, 11 (78.57%) patients were males and 03 (21.43%) patients were females showing male preponderance. Out of the 14 cases, 09 (64.29%) cases were closed fractures and 05 (35.71%) cases were open fractures. At the end of 12 months of the 14 patients treated, 02(14.29%) patients had excellent outcome, 07 (50%) had good results, 03 (21.42%) had fair outcome and 02(14.29%) patient had a poor result. Only 2 (14.29%) cases were having ankle stiffness followed by superficial skin infection (7.14%) and deep infection (7.14%).
The impact of alkanes on the structure of Triton X100 micelles

Here we investigate the structural evolution of TX100 micelles upon loading with several linear and cyclic alkanes by DLS, PGSE-NMR, 2D NOESY NMR, viscosity measurements, and molecular dynamic simulations. Our results confirm that TX100 alone forms spherical, onion-like micelles made of several partially interpenetrating surfactant layers where the polyethylene glycol chains are in contact with the tetramethyl-butyl-phenyl moieties. Loading with non-penetrating oils larger than decane induces a decrease in micellar size and hydration because the alkane molecules compete with both water and tetramethyl-butyl-phenyl groups for the polyethylene glycol chains. This results in the partial peeling of the “onion” and in the dehydration of polyethylene glycol chains so that the micelles increase in number and decrease in size upon alkane loading. In contrast, small and penetrable oils (mainly cyclo-alkanes) first swell the onion-like micelles (inducing an increase in size) and only above a critical oil/surfactant ratio does the oil induce the weakening of the multilayer structure and the dehydration of polyethylene glycol chains found in long linear alkanes.
Corporate-Sovereign Debt Nexus and Externalities

I show that corporate debt accumulation during booms can explain increases in sovereign risk during stress periods. Using idiosyncratic shocks to large firms as instruments for aggregate corporate leverage, I show that rising corporate leverage during the period 2002-2007 causally increases sovereign spreads in six Eurozone countries during the debt crisis period of 2008-2012. To explain these findings, I build a dynamic quantitative model in which both firms and the government can default. Rising corporate debt increases sovereign default risk, as tax revenues are expected to decrease. Externalities arise because it can be privately optimal but socially suboptimal for firms to default given their limited liability. The fact that firms do not take into account the effect of their debt accumulation on aggregate sovereign spreads is an important externality, rationalizing macroprudential interventions in corporate debt markets. I propose a set of such optimal debt policies that reduce the number of defaulting firms, increase fiscal space, and boost household consumption during financial crises. Both constant and countercyclical debt tax schedules can correct overborrowing externalities. Contrary to conventional wisdom, countercyclical debt policy is less effective than constant debt policy, as the countercyclical policy induces more firm defaults.
Chapter 3 Subsidizing Innovation over the Business Cycle * 3 . 1

The global economic and financial crisis that unleashed in 2008 had a negative impact on R&D and innovation globally. In the OECD countries as a whole the growth rate of GDP fell by 3.5% in 2009, while business R&D investment dropped by 4.2% (OECD-STI 2014). Investment in R&D has exhibited, at this highly aggregate level, a pro-cyclical behavior over the last twenty years, according to data published by the OECD. The growth rate of GDP and of gross domestic R&D investment have been positively correlated over the period 1996-2016, with a correlation coefficient of about +0.70. This mirrors mostly the behavior of business R&D, since the correlation between GDP and of public R&D expenditure growth rates has been negative across that same period, with an absolute value of 0.34, which is suggestive of a mildly counter-cyclical behavior on average. The potential threat to long-term growth derived from reduced business R&D effort in downturns may thus have been partially mitigated by public investment. A closer look at the data shows that public investment in R&D took different paths in different countries around 2008/9. While increasing in Germany and Austria, they fell in France, Spain and Italy (OECD-STI 2014). In the US the real growth rate of Federal government R&D was positive until 2011, but turned negative in subsequent years; nonfederal government growth rates were negative since 2011 (Foundation 2018). Since then a declining trend is observed both sides of the
Self-image Bias and Lost Talent

We propose an overlapping-generations model in which established researchers evaluate the research of new researchers. All researchers are differentially endowed with equally desirable research characteristics and belong to two groups, M or F, which have identical ex-ante productivity distributions. Evaluations are group-blind. Yet, when research is evaluated on many characteristics, evaluators' self-image bias and mild between-group heterogeneity lead the initially larger group, say M, to dominate indefinitely. M-researchers only accept the research of young scholars with characteristics close to theirs. Promoted F-researchers are thus few and "similar" to M-researchers, perpetuating the asymmetry. This talent loss is exacerbated by candidates' career concerns and institutions' focus on hiring faculty whose research will be approved by established researchers. Mentorship reduces group imbalance, but it increases the F-group talent loss. Affirmative action reduces both. Our model's predictions are consistent with existing empirical evidence on female participation in academic economics.
Peripheral immunity in parkinson's disease associated to chronic infections: A report of two cases

Parkinson’s disease (PD) is the second most frequent neurodegenerative disorder worldwide. PD is characterized by loss of dopaminergic neurons where neuroinflammation plays an important role. Moreover, there has been found changes in peripheral immune response that may contribute to its pathogenesis. Patients with PD aren’t exempt to have concomitant diseases, such as chronic infections that may modify their immune response and contribute to the development of the disease. In this study we present two cases of PD patients, one with concomitant syphilis and the other with chronic hepatitis virus C (CHVC) infection. We determinate their peripheral immune phenotypes by flow cytometry and plasma cytokines concentrations by ELISA. In both patients, T CD4+ cells showed higher percentages than CD8+ T cells, total B cells, CD8+ lymphocytes, classical Tregs and active Tregs were higher in the CHCV infected patient as well as the levels of IFNγ and IL-10 compared to the syphilitic patient. On the other hand, the syphilitic patient showed a higher level of Th2 response than the CHCV infected patient. The peripheral immune response in both patients is mostly due to the chronic infections, but the results suggest that PD could contribute to the progression of these diseases and promote worse outcome for the patients, specially the one with concomitant syphilis. *Correspondence to: Laura Adalid-Peralta, Ph D, Unidad Periférica para el estudio de la Neuroinflamacion del Instituto de Investigaciones Biomédicas en el Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez.

Multifaceted role of polyamines in bacterial adaptation

oxidative stress in bacteria exposed to antibiotics. The polyamine protective effect could be due to either the scavenging of ROS or interfering with the binding of antibiotics to target macromolecules. To assess the contribution of each mechanism, a comparative study of the effect of polyamines (putrescine, cadaverine, spermidine, and 1,3-diaminopropane) and wellknown antioxidants (Trolox, thiourea) on the intensity of reactive oxygen species production in vitro as well as the survival of Escherichia coli cells exposed to antibiotics was carried out. Polyamines diminished the generation of superoxide in NADH/phenazine methosulfate reaction and neutralized H2O2 at least 20-fold less effectively than the antioxidants. Polyamines and antioxidants had no discernible effect on the antibacterial activity of β-lactam cefotaxime. Cadaverine reduced the decline in the CFU number caused by aminoglycoside amikacin by 2.7 orders of magnitude, while the other polyamines did by approximately 2 orders. The latter was 2 and 10 times higher than the effects of Trolox and thiourea, respectively. Under fluoroquinolone levofloxacin treatment, the protective effect of polyamines increased with an increase in their ability to bind DNA (cadaverine<putrescine<diaminopropane<spermidine). Addition of spermidine resulted in an increase in the CFU number by 2 orders, which was 10 times lower than the effect of Trolox and 10 times higher than that of thiourea. The protective effect of polyamines on bacteria exposed to antibiotics is rather related to their ability to bind macromolecules including those targeted by antibiotics than to their properties to scavenge reactive oxygen species.

Results: There was a significant difference between the two groups in daily performance variables (p = 0.005) and total sleep quality score (p = 0.001). It was also found that active women with cesarean section had better condition than inactive women with cesarean section. There was a significant difference between the two groups in the variables of sleep disorders (p = 0.005) and total sleep quality score (p = 0.001).
HPLC Method Development and Validation for Simultaneous Analysis of Diclofenac Sodium and Rabeprazole Sodium

A stable, simple, rapid, precise, accurate RP-HPLC method for simultaneous analysis of diclofenac sodium and rabeprazole sodium was developed and validated as per ICH guidelines without need of any internal standard. Separation was carried out using C8 column with triethyl amine buffer (pH 5): acetonitrile (50:50 v/v) as mobile phase with flow rate 2 mL min-1. The detection was carried out at 284 nm. The parameters studied were retention time, linearity and range, accuracy, precision, detection limit, quantitation limit and bench top stability. The proposed method can be used for simultaneous estimation of diclofenac sodium and rabeprazole sodium in bulk drugs and pharmaceutical dosage forms.

6D Pose Estimation of Transparent Object From Single RGB Image for Robotic Manipulation

Grasping and manipulating transparent objects with a robot is a challenge in robot vision. To successfully perform robotic grasping, 6D object pose estimation is needed. However, transparent objects are difficult to recognize because their appearance varies depending on the background, and modern 3D sensors cannot collect reliable depth data on transparent object surfaces due to the translucent, refractive, and specular surfaces. To address these challenges, we proposed a 6D pose estimation of transparent objects for manipulation. Given a single RGB image of transparent objects, the 2D keypoints are estimated using a deep neural network. Then, the PnP algorithm takes camera intrinsics, object model size, and keypoints as inputs to estimate the 6D pose of the object. Finally, the predicted poses of the transparent object were used for grasp planning. Our experiments demonstrated that our picking system is capable of grasping transparent objects from different backgrounds. To the best of our knowledge, this is the first time a robot has grasped transparent objects from a single RGB image. Furthermore, the experiments show that our method is better than the 6D pose estimation baselines and can be generalized to real-world images.
A German Corpus on Topic Classification and Success of Social Media Posts from Facebook

We provide a corpus consisting of 6,000 posts of German food delivery services from five brand pages on the online social network Facebook. The brand pages include Call a Pizza, Deliveroo, Domino’s, Lieferando, Mundfein and Smiley’s. A group of social media marketing experts annotated each post with one or more topic labels from eleven marketing related categories describing its content. Additionally an assessment on the success of the social media post is provided as a binary label. The interrater reliability over all annotators according to Fleiss’ Kappa is 0.4835 for the topics and 0.6674 for success. Furthermore, baseline measurements with machine learning based text classification with an F1-score up to 0.7173 are presented as a first experiment on this new corpus. The data set of the corpus on German topic classification and success (GTCS6k) is publicly available here: https://ccwi.github. io/corpus-gtcs6k
Automatic Classification of Disaster-Related Tweets

 Abstract — The social networking site Twitter has become one of the quickest sources of news and other information. Twitter information feeds known as tweets, are voluntarily sent by registered users and reach even non-registered users, sometimes ahead of traditional sources of mass news. In this study, we develop some machine learning models that can automatically detect informative disaster-related tweets. A dataset of tweets, collected during the Habagat flooding of Metro Manila in 2012, was used in building the classifier models. A random subset of this dataset was manually labeled as either informative or uninformative to produce the ground truth. Two machine learning algorithms, Naive Bayes and Support Vector Machine (SVM), were used to build models for the automatic classification of the tweets, and these models were evaluated across the metrics of accuracy, precision, recall, area under curve and F-measure. Experimental results show that the model generated from SVM has significantly better results compared to that of the Naive Bayes. This study also revealed that uninformative tweets outnumbered informative tweets, suggesting that the subscribers used Twitter to broadcast more of tweets that express their subjective messages and emotions regarding the Habagat event. However, the informative tweets were more likely to be retweeted than uninformative tweets, indicating that subscribers retweet messages they deem informative and useful for public awareness. These insights, together with the built classifier models, can help in the development of a system that can sift through the voluminous Twitter data and in real-time detect informative disaster-related tweets so that appropriate action may be done promptly.
KINETICS OF HYDROXYMETHYLFURFURAL ACCUMULATION AND COLOR CHANGE IN HONEY DURING STORAGE IN RELATION TO MOISTURE CONTENT

ABSTRACT Quality reduction in honey during storage is indicated by hydroxymethylfurfural (HMF) accumulation and darkening of color. The effects of moisture content and temperature on HMF accumulation and color change in honey during storage were investigated. HMF accumulation and color change followed first- and zero-order reaction kinetics, respectively. The moisture content affected the rate of the two degradation reactions depending on the storage temperature. Reduction in moisture content caused an increase in rate constant for HMF accumulation at 20 and 30C, but there was no significant effect of moisture content at 40C. Rate constants for change in lightness and total color change values increased with increasing moisture content at 20 and 30C. The highest rate constant for change in color values was obtained at a moisture content of 18% at 40C. PRACTICAL APPLICATIONS Hydroxymethylfurfural accumulation and color change are two major quality degradations in honey during storage. This study shows that the rates of these two degradations are dependent on moisture content of honey. In addition, effect of moisture content on the rates of reactions was dependent on temperature of storage. Therefore, producers need to consider the effects of both moisture content and storage temperature in reducing quality loss in honey during storage.
