A package for the automated classification of periodic variable stars

We present a machine learning package for the classification of periodic variable stars. Our package is intended to be general: it can classify any single band optical light curve comprising at least a few tens of observations covering durations from weeks to years with arbitrary time sampling. We use light curves of periodic variable stars taken from OGLE and EROS-2 to train the model. To make our classifier relatively survey-independent, it is trained on 16 features extracted from the light curves (e.g., period, skewness, Fourier amplitude ratio). The model classifies light curves into one of seven superclasses – δ Scuti, RR Lyrae, Cepheid, Type II Cepheid, eclipsing binary, long-period variable, non-variable – as well as subclasses of these, such as ab, c, d, and e types for RR Lyraes. When trained to give only superclasses, our model achieves 0.98 for both recall and precision as measured on an independent validation dataset (on a scale of 0 to 1). When trained to give subclasses, it achieves 0.81 for both recall and precision. The majority of misclassifications of the subclass model is caused by confusion within a superclass rather than between superclasses. To assess classification performance of the subclass model, we applied it to the MACHO, LINEAR, and ASAS periodic variables, which gave recall/precision of 0.92/0.98, 0.89/0.96, and 0.84/0.88, respectively. We also applied the subclass model to Hipparcos periodic variable stars of many other variability types that do not exist in our training set, in order to examine how much those types degrade the classification performance of our target classes. In addition, we investigate how the performance varies with the number of data points and duration of observations. We find that recall and precision do not vary significantly if there are more than 80 data points and the duration is more than a few weeks.
Effectiveness of safe child birth checklist on maternal and perinatal outcomes in tertiary level hospitals

Background: The World Health Organization (WHO) estimates nearly 2,87,000 maternal deaths, 1 million intrapartum related stillbirths and another 3 million new born deaths during the neonatal period against more than 130 million births each year. Intrapartum perinatal mortality, the deaths that occur during the period around birth, is a major problem in developing countries Objective of this study is to study the effectiveness of safe child birth checklist on maternal and perinatal outcomes in tertiary level hospitals.Methods: This study is a hospital based prospective interventional study conducted at MGMH, Petlaburzu hospital, Hyderabad, Telanagana, which is a tertiary care hospital comes under Osmania medical college. 635 deliveries were followe up without SCC and 620 deliveries were followed up with SCC.Results: There was significant improvement in starting of partograph at the time of admission with SCC (20% vs 32.2%), more number of cases required to start antibiotics in with SCC group compared to without SCC. Just Before and during Birth (or C-Section) without SCC group significantly more need to start Antibiotic compared to with SCC group (15.7% vs 11.3%) and active management of third stage of labour was significantly more among with SCC group (94.5% vs 96.9%). Conclusions: In final mortality and morbidity outcomes of delivery i.e. maternal and perinatal, the effectiveness of implementation of safe child birth check list has no significant effect though there were improved set of certain practices during the child birth process.
Seroprevalence of Q fever in farm animals in Saudi Arabia

This study was undertaken to determine the seroprevalence of Q fever in domestic livestock in Saudi Arabia. Serum samples from 489 camels, 428 cattle, 630 sheep and 423 goats, of either sex, from different localities were tested for antibodies against C. burnetii using a Q fever indirect enzyme-linked immunosorbent assay (ELISA). A subsample of 307 animals of different species was simultaneously tested for C. burnetii antibodies by ELISA and indirect immunofluorescence (IFA). The overall seroprevalence was 30.71%. Prevalence by species was 51.53%, 30.67%, 34.04% and 12.38% in camels, cattle, goats and sheep, respectively. Significant differences in seroprevalence were recorded between species and locations. The prevalence was overtly higher in adult as compared to young animals. No significant difference was recorded between male and female animals. There was a close agreement between ELISA and IFA results in cattle and camels while the results of the two tests were at variance in sheep and goats. The results indicate that the domestic livestock and the camel are the source of Q fever endemicity in Saudi Arabia.
Ideologies in Mandela’s No Easy Walk to Freedom

Ideology has great influence on the traits and behaviors of leaders. It is the vehicle by which we could understand our leaders and our leaders could understand us. The present paper is an endeavor to reveal the ideological dimension that is embedded in the discourse of Nelson Mandela, with special reference to his address No Easy Walk to Freedom which was delivered in 1953. It is conducted on the approach of Critical Discourse Analysis. Van Dijk's (2004) Political Ideological Strategies and Wodak's (2005) Discursive Strategies of Positive Self- and Negative Other-Presentation were accommodated to achieve the objective of the study. The findings demonstrated that Van Dijk's strategies of actor description, positive self-presentation and negative other-presentation and Wodak's two chosen strategies of argumentation and perspectivation were supportive in exploring the ideologies penetrated in Mandela's discourse. They five strategies proved to be helpful devices in exploring the fundamentally embedded ideologies in Mandela's discourse which are "white superiority" and "black inferiority". White superiority was the ideological foundation of the white minority to establish the apartheid system in South Africa for decades, whereas black inferiority was the ideological foundation of the black majority to sustain different forms of resistance against the white governments. Therefore, it could be perceived that the social acts of both the blacks and the whites were formed and structured in terms of these two ideological foundations.
Distributed evolutionary games

Standard population models in ecology and evolutionary ecology assume that all individuals are identical and reproduce by cloning. Often, the connection between evolutionary ecology, genetics and mating systems is not explicit. Functionally similar species are modelled with separate equations (e.g. 'competing' species). Here, a theory is developed that: (i) views a population as a distribution of individuals over adaptive character values; (ii) identifies various evolutionary types (e.g. species) with special points along this distribution; (iii) treats individuals as different with respect to the adaptive character value; (iv) incorporates ecological interactions among individuals along distributions; and (v) incorporates assortative mating and mutations. A stable equilibrium distribution of individuals over the adaptive character (the strategy) is a distributed evolutionarily stable strategy (ESS). At the distributed ESS, individuals may be equally distributed over all values of the adaptive character. Conditions that give rise to a non-uniform distributed ESS are analysed. Organisms are classified into types - an abstract classification for which species, phenotypes, and so on are special cases. With distributions, when the stable distribution is not homogeneous with respect to the adaptive character, it makes no sense to talk about the fitness of an individual in isolation from that of others. We talk about a fitness distribution. At a distributed ESS, the distribution of fitness is stable and different individuals have different values of the adaptive character. The theory is extended to multiple characters and functionally different organisms (predators, prey, etc.). It remains intact with evolution of multiple characters with multiple ecological interactions in space and with mutations and assortative mating. A way to link distributed evolutionarily stable strategies to genetic mechanisms is outlined.
Hadza Women's Time Allocation, Offspring Provisioning, and the Evolution of Long Postmenopausal Life Spans

Extended provisioning of offspring and long postmenopausal life spans are characteristic of all modern humans but no other primates. These traits may have evolved in tandem. Analysis of relationships between women's time allocation and children's nutritional welfare among the Hadza of northern Tanzania yields results consistent with this proposition. Implications for current thought about the evolution of hominid food sharing, life history, and social organization are discussed.
Assessment of Nurses' Knowledge Concerning Cardiogenic Shock for Patients' in Cardiac Care Unit at Baghdad Hospitals

Background: The contemporary in hospital mortality rate for cardiogenic shock remains extremely high. Cardiogenic Shock can occur as a result of a wide variety of cardiac disorders, Including ACS, valvular disease, myocardial and pericardial disease, congenital lesions, and mechanical injuries to the heart. Objective(s): The study objectives are to assess of nurses' knowledge concerning cardiogenic shock for patients in the Cardiac Care Unit at public teaching hospitals and to finding out the relationship between the nurse's Knowledge and the demographic characteristics that includes (age, gender, level of education, years of experience, and training session). Methodology: A descriptive study which was using the quantitative design. The study was conducted at the Medical City/ Baghdad Teaching Hospital; In-Alnafes Teaching Hospital, and Ibn-Albettar Teaching Hospital starting in November 15th 2012 up to the March 30th 2013. To achieve the objectives of the study, A non-probability (purposive) samples of (50) a nurse who was consisted of all nurses who provide nursing care for patients which suffering from various cardiac diseases including cardiogenic shock and according to special criteria. Data were collected by an application of direct interview as a means of data collection. Nurses were interviewed while they are working in the cardiac care unit during the day. Instrument validity was determined through content validity, by a panel of experts. Reliability of the instrument was determined through detected of Cronbach's alpha via split half technique on sample of (10) nurses, which was (0.74). Analysis of data was performed through the application of descriptive statistics (frequency, percentage, mean of score, Relative sufficiency) and inferential statistics, significance and correlation coefficient. Results: The results of the study indicated the evaluation of the mean of scores and relative sufficiency for nurse's knowledge regarding cardiogenic shock for patients in the cardiac care unit was out of comparison and there is no significant association between training session of sample and nurses' knowledge. While there is high significant association between ages, gender, level of education, years of experience in cardiac care unit and nurses' knowledge. Conclusion: The study concluded most of nurses that work in cardiac care unit have high knowledge about cardiogenic shock in some questions. Recommendations: The study emphasize that hospitals and health organizations should be applying flexible and responsible steps to facilitate passages for better level for junior nurses and those who need high graduated level to improve their skills and knowledge towards nursing care of patients with cardiogenic shock, as well as the nature of cardiogenic shock.
Determination of Protein, Lipid and Carbohydrate Contents of Conventional and Non-Conventional Feed Items Used in Carp Polyculture Pond

A study was conducted during April’2010-September’2010 with a view to compare the protein, lipid and carbohydrate contents in conventional and non-conventional feed items and to recommend suitable strategy in selecting feed item for the development of weed based fish farming in carp polyculture pond. The experiment was carried out at the Protein and Enzyme Research Laboratory, Department of Biochemistry and Molecular Biology, Rajshahi University, Rajshahi. Six different conventional and non-conventional fish feed items like rice bran, wheat bran, mustard oilcake, Azolla, grass and banana leaves were tested to determine the nutrient contents under 6 treatments as T1, T2, T3, T4, T5 and T6, respectively. In this study, nutrient contents (protein, lipid and carbohydrate) were monitored monthly. Significant variations (P<0.05) were found in the mean values of nutrient contents with different treatments of feed items but in case of same feed item no significant difference was found in the nutrient content at different months. Among the non-conventional feed items treatment T4 (Azolla) varied more significantly (P<0.05) for the mean values of protein content. Findings indicated that Azolla was more nutritive and low cost effective diets for fish farming in Bangladesh.
Development of an IPM programme for Californian avocados

SYNOPSIS Avocado acreage in California has increased dramatically during the past 15 years, presenting greater opportunities for pest species to become established. A synthetic pheromone for Amorbia cuneana (Walsingham), a major pest of avocados, has been developed for use in the detection and monitoring of population outbreaks. Through the use of this pheromone, new Amorbia species have possibly been discovered.

This includes individual, organisational, and socio-economic levels of analysis. The authors examine the administrative processes for Structural Funds implementation in four case study regions in Italy (Puglia, Sicilia) and Poland (Malopolskie, Pomorskie). Based on semi-structured interviews conducted with civil servants and key stakeholders at the regional level, the chapter presents the key variables (both administrative and institutional) which have an impact on the Managing Authorities’ performance. Finally, the paper outlines the ‘lessons learnt’ from the implementation of EU Cohesion Policy in these regions.
Emotional and Behavioral Disorders ( EBD ) and Achievements of Grade 1 Pupils April

Emotional and behavioral disorders are potential causes of disciplinary problems in the classroom. The main interest of the study is the EBD and achievements of Grade 1 pupils in public schools of South Cotabato. About 210 Grade One pupils and teachers were involved as subjects and respondents of this inquiry. A questionnaire in EBD was given to teachers for them to carefully assess the pupils’ ODD, CD and ADHD level. The survey tools were modeled after the Noanxiety.com resources and the Vanderbilt Rating Scales. Records of pupils’ gender, curricular and extracurricular achievements were taken from the teachers’ own class records. Gathered data were suitably tabulated and presented in tables and chart. Both descriptive and inferential statistics were applied to treat the data. Specific tools like percentages, Multiple Linear Regression Analysis, mean and t-test were employed to analyze the collected data. As found out, the Grade 1 pupils’ EBD level is singly, and collectively of moderate levels. They have very good level in curricular and extra-curricular achievements alike. Male pupils have relatively higher EBD level than the females. Inversely, the female pupils have comparatively higher achievement than the males. The pupils whose schools were located in highly urbanized places have higher EBD level than those in the less urbanized areas. Also, the achievements of the pupils from schools situated in less urbanized areas were higher than those in the highly urbanized areas. This study concluded that only the pupils’ attention deficit hyperactivity disorder was linked to pupils’ achievement. Gender and school location also affected pupils’ EBD and achievement levels.
Na2SO4 and MgSO4 salts during the Holocene period derived by high-resolution depth analysis of a Dome Fuji ice core

Abstract We analyzed the profiles of ionic chemical species in three 500 mm sections of an ice core from Dome Fuji, Antarctica, dated 3.0, 8.9 and 13.3 kyr BP (before present), and compared the profiles to those in the surface snow. The 3.0 and 8.9 kyr sections are from the Holocene and the 13.3 kyr section slightly predates the Holocene. The analyses were done on 2 mm thick slices within each section. At each depth, the primary ionic species were Na+, H+, Cl– and SO4 2 A The SO4 2, Na+ and Mg2+ levels varied with depth in each section over distances ranging from several millimeters to several centimeters. Also, the correlation coefficients between Na+ and SO4 and between Mg2+ and SO4 2 for each depth were 0.90 or greater, in contrast to the value of 0.59 or less in the surface snow (defined here as 0–3.4 m from the surface). These results suggest that almost all Na+ and Mg2+ in the Holocene ice exists as Na2SO4 and MgSO4 salts, and the formation of these salts occurs not only in the atmosphere during transport, but also in the firn layer.
Students' Ideas about Dangerous Animals.

The aim of this article was to study the concepts and thoughts of primary education students about dangerous animals. A total of 316 primary education students attending a primary school in Turkey participated in the study. The research data was obtained through open-ended questions and word association tests. Data obtained from the questions directed at the students were analysed one-by-one. As the students made many associations, words of the same or similar meaning were coded together. Associations encountered less than three times, and those that could not be coded with the others, were removed. Certain categories were formed according to relationships of meaning, and the usage frequency of the words in each category was calculated quantitatively. As a result of the analysis of the data, it was found that students considered the features that make animals dangerous include: being venomous, having a large size, being vicious and wild, and also
Assessing land-ocean connectivity via submarine groundwater discharge (SGD) in the Ria Formosa Lagoon (Portugal): combining radon measurements and stable isotope hydrology

Abstract. Natural radioactive tracer-based assessments of basin-scale submarine groundwater discharge (SGD) are well developed. However, SGD takes place in different modes and the flow and discharge mechanisms involved occur over a wide range of spatial and temporal scales. Quantifying SGD while discriminating its source functions therefore remains a major challenge. However, correctly identifying both the fluid source and composition is critical. When multiple sources of the tracer of interest are present, failure to adequately discriminate between them leads to inaccurate attribution and the resulting uncertainties will affect the reliability of SGD solute loading estimates. This lack of reliability then extends to the closure of local biogeochemical budgets, confusing measures aiming to mitigate pollution. Here, we report a multi-tracer study to identify the sources of SGD, distinguish its component parts and elucidate the mechanisms of their dispersion throughout the Ria Formosa – a seasonally hypersaline lagoon in Portugal. We combine radon budgets that determine the total SGD (meteoric + recirculated seawater) in the system with stable isotopes in water (δ2H, δ18O), to specifically identify SGD source functions and characterize active hydrological pathways in the catchment. Using this approach, SGD in the Ria Formosa could be separated into two modes, a net meteoric water input and another involving no net water transfer, i.e., originating in lagoon water re-circulated through permeable sediments. The former SGD mode is present occasionally on a multi-annual timescale, while the latter is a dominant feature of the system. In the absence of meteoric SGD inputs, seawater recirculation through beach sediments occurs at a rate of ∼ 1.4 × 106 m3 day−1. This implies that the entire tidal-averaged volume of the lagoon is filtered through local sandy sediments within 100 days ( ∼ 3.5 times a year), driving an estimated nitrogen (N) load of ∼ 350 Ton N yr−1 into the system as NO3−. Land-borne SGD could add a further ∼ 61 Ton N yr−1 to the lagoon. The former source is autochthonous, continuous and responsible for a large fraction (59 %) of the estimated total N inputs into the system via non-point sources, while the latter is an occasional allochthonous source capable of driving new production in the system.
Temporal Trend in the Transfer of Sellafield-Derived 14C into Different Size Fractions of the Carbonate Component of NE Irish Sea Sediment

From 1994 onwards, radiocarbon discharges from the Sellafield nuclear fuel reprocessing plant have been made largely to the northeast Irish Sea. They represent the largest contributor to UK and European populations of the collective dose commitment derived from the entire nuclear industry discharges. Consequently, it is important to understand the long-term fate of 14C in the marine environment. Research undertaken in 2000 suggested that the carbonate component of northeast Irish Sea sediments would increase in 14C activity as mollusk shells, which have become enriched in Sellafield-derived 14C, are broken down by physical processes including wave action and incorporated into intertidal and subtidal sediments. The current study, undertaken in 2011, tested this hypothesis. The results demonstrate significant increases in 14C enrichments found in whole mussel shells compared to those measured in 2000. Additionally, in 2000, there was an enrichment above ambient background within only the largest size fraction (>500 μm) of the intertidal inorganic sediment at Nethertown and Flimby (north of Sellafield). In comparison, the present study has demonstrated 14C enrichments above ambient background in most size fractions at sites up to 40 km north of Sellafield, confirming the hypothesis set out more than a decade ago.
A simple method for the quantification of a class of labile marine pico- and nano-sized detritus: DAPI Yellow Particles (DYP)

A simple and rapid method for microscopic quantification of an abundant class of labile picoand nano-sized detrital particles (0.2 to 20 pm), using the fluorochrome stain DAPI, is described. Using an appropriate UV-filter set, examination of DAPI-stained samples revealed not only blue (DNAcontaining) but also yellow particulate matter. We showed that DAPI yellow fluorescing particles resembled detritus made from plankton tow material or copepod faecal pellets and were almost exclusively organic, enzyme-degradable matter. Quantification of the total surface area of these particles in the Ligurian Sea (NW Mediterranean) revealed stocks averaging 80 mm2 I-' in surface layer waters. The possible origin and fate of these picoand nano-sized DAPI Yellow Particles (DYP) are discussed.
