Discovery of a brown dwarf companion to the star HIP 64892

We report the discovery of a bright, brown dwarf companion to the star HIP 64892, imaged with VLT/SPHERE during the SHINE exoplanet survey. The host is a B9.5V member of the Lower-Centaurus-Crux subgroup of the Scorpius Centaurus OB association. The measured angular separation of the companion (1.2705 ± 0.0023”) corresponds to a projected distance of 159 ± 12 AU. We observed the target with the dual-band imaging and long-slit spectroscopy modes of the IRDIS imager to obtain its spectral energy distribution (SED) and astrometry. In addition, we reprocessed archival NACO L-band data, from which we also recover the companion. Its SED is consistent with a young (<30 Myr), low surface gravity object with a spectral type of M9γ ± 1. From comparison with the BT-Settl atmospheric models we estimate an effective temperature of Teff = 2600 ± 100 K, and comparison of the companion photometry to the COND evolutionary models yields a mass of ~29−37 MJ at the estimated age of 16−7+15 Myr for the system. The star HIP 64892 is a rare example of an extreme-mass ratio system (q ~ 0.01) and will be useful for testing models relating to the formation and evolution of such low-mass objects.
Inflation targeting and exchange rate pass through in Pakistan: Markov switching approach

This study uses Markov switching model to empirically track the existence of exchange rate pass through and inflation trends in Pakistan from 1982 to 2016. The results reveal a direct relationship between pass through and inflation. Furthermore, interest rate and trade variables have a significant impact on inflation. According to the smoothed probabilities, switches between regimes were sudden and sporadic till 1990, after which long spells were observed during high and low inflation regimes.
Supply Response Analysis of Rice Growers in District Gujranwala, Pakistan

The study was designed to estimate the restricted profit function in district Gujranwala, Punjab, Pakistan. Data were collected from 100 respondents using proportional allocation sampling tech-nique. The analysis was done using SHAZAM software. The results indicate that the farmers are price-responsive. Rice own price elasticity was 1.873. The output supply elasticity of rice with re-spect to education, land, fertilizer price and irrigation cost were 0.0. 169, 1.274, -0.873 and -0.953 respectively. Irrigation demand elasticity with respect to education, land, fertilizer price, irrigation cost and output price were 0.14, 1.14, -0.783, -1.84 and 1.78 respectively. Fertilizer demand elasticity with respect to education, land, fertilizer price, irrigation cost and output price was 0.023, 0.792, -1.65, -0.85 and 1.851 respectively. Lastly, the elasticity of profit with respect to education, land, fertilizer price, irrigation cost and output price was 0.20, 1.10, -0.83, -1.136 and 1.92 respectively. The study recommends that Government should provide consistent electricity with stable rates, so that, they irrigate their fields through electric tube wells and ultimately their cost of irrigation decreases. The study also suggests that government should stabilized fertilizer prices to encourage its application. Furthermore, government should raise procurement price of rice to encourage its supply this; it in turn will also increase the profit of the farmer.
Evaluating Effects of Financial Leverage on Future Stock Value at Stock Exchange

The present study mainly aims at evaluating effects of financial leverage on future stock value (emphasizing industry type). This is an applied and correlation study considering objective and method, respectively. The research statistical population was consisted of those Tehran stock exchange listed active cement industry companies analyzed from 2005 to 2008. Research findings relying on correlation and regression analysis indicates inefficiency of financial leverage on future value of Tehran stock exchange listed companies. In other words, the criterion is not helpful in predicting future value and lacks significant explanatory power. Based on research results, considering financial leverage criterion, therefore, will not be useful in predicting future value.
Conceptualising the Role of Reciprocity in Relationship Marketing: An Examination of its Supporting Virtues

One possible “kind” of marketing relationship occurs where a norm of reciprocity is upheld. The norm states that “we should return good for good, in proportion to what we receive; we should resist evil, but not do evil in return; we should make reparation for the harm we do;. furthermore that obligations should be felt in retrospect” (Becker, 1990, p.4). The appeal of this kind of exchange is that it provides the participants with traits that enable them to pursue excellence in moral behaviour. Making the assumption that societal goal is good moral citizenship; this could be the perfect relationship. It is therefore a good starting point toward examining other types. However, “Reciprocity, taken by itself is insufficient for its own purposes” (Becker, 1986, p.150). It relies on a number of supporting virtues. This paper builds on previous work that conceptualises the role of reciprocity in relationship marketing by examining these virtues. For the norm to effectively stabilize marketing relationships it relies on the presence of other virtues, these include, generosity, conviviality, empathy, and practical wisdom (Becker, 1986). These traits are explored within the context of reciprocity and supporting relationship marketing literature.
Right to Buy? Time to Move? Investigating the Effect of the Right to Buy on Moving Behaviour in the UK

One of the goals of the Right to Buy (RTB) was to stimulate labour migration by removing the debilitating effect of social housing on geographical mobility. This is the first study to examine rigorously whether the Right to Buy legislation did indeed 'free-up' those in social housing who bought their homes. Using longitudinal data from the British Household Panel Survey (BHPS) and panel regression models we show that the probability of a RTB-owner making a long distance move falls between that of social renters and owner occupiers. However, the difference between RTB-owners and neither homeowners nor social renters is significant. Social renters are significantly less likely to move over long distances than traditional owners. The results also suggest that RTB-owners are less likely than traditional owners to move for job related reasons, but more likely than social renters.
PERCEPTION IF QUALITY OF WO RKING-LIFE AND UNIVERSITY GOAL ATTAINMENT IN THE SOUTH – SOU TH GEO-POLITICAL ZONE OF NIGERIA

This study was designed to have some understanding of the Quality of Work -Life (QWL ) of university academic staff and to relate this understanding to their per formance towards university goal attainment (UGA) in the SouthSouth Geo Political Zone of Nigeria. Two research q uestions and two null hypotheses were raised to exa mine the QWL of university academic staff, university goal a ttainment. The significance of the study is to help those involved in higher educational planning, policy formulation and implementation to achieve optimum university ou tc mes through performance and QWL of academic staff. The study was guided by a theoretical framework on self -th ory with a plethora of self-based theories on QWL and u iversity goal attainment. The review indicated tha t only very limited work had been done in this area in Nigeria, on university academics as subjects. The sample co nstituted 1681 university academic staff and this was 36% of the entire population of academic staff in the Zone . Two Questionnaires were each developed for QWL and UGA respectively in addition to personal interviews and document review. The design of the study was that o f descriptive survey while the stratified samplin g technique was adopted to select the four sampled universities . The level of significant was that of 0.50. Result s of the study revealed a state of satisfactory QWL for the staff; state of unfavourable University goal attainment ; and insignificant relationship between QWL and UGA in t he universities. These results are unique in the se nse that they revealed that satisfactory QWL of university academ ic staff does not generate commensurate satisfactor y UGA in the Nigeria Universities.
The welfare effects of asset mean‐testing income support

This paper studies the savings and employment effects of the asset means‐test in US income support programs using a structural life‐cycle model with productivity, disability, and unemployment risk. An asset means‐test incentivizes low‐income households to hold few financial assets making them vulnerable to predictable and unpredictable income changes. Moreover, it incentivizes relatively productive households that happen to have few financial assets to leave the labor force. However, it allows for relative generous transfers to households in most need. Moreover, it counteracts relatively productive households leaving the labor force after the age of 50. In terms of the welfare of an unborn household, the asset means‐test that optimally trades off these effects is $150,000, and abolishing it is close to optimal.
The Determinants of Financial Euroization in a Post-Transition Country: Do Threshold Effects Matter? *

This paper investigates the long-run and short-run determinants of financial euroization (FE) using both linear and threshold models. We model deposit euroization (DE) and credit euroization (CE) in Croatia, a post-transition country recording very high and persistent unofficial FE. The results suggest that only the portfolio view is important for explaining DE and CE. The market failure view does not seem to matter for FE in Croatia. Both nominal and real exchange rate changes have a strong effect on FE in the long run; the former is more important for DE and the latter for CE. In the short and long run CE is also determined by matching behavior of banks’ foreign currency positions. Both DE and CE respond to changes in inflation and exchange rate volatility. Threshold cointegration confirms that FE determination is subject to significant threshold effects, while error correction models suggest that FE adjustment is very slow and asymmetric, partly due to very strong FE persistence.
enfermeros sobre seguridad del paciente en el servicio de emergencia : un estudio cualitativo Nurses ’ perceptions of patient safety in the emergency setting : a qualitative study

Nurses are in a key position to improve the quality of healthcare through patient safety interventions and strategies. However, there is a general misunderstanding of the effects of the numerous and complex work environment factors on patient safety. This qualitative study aims to explore nurses’ perceptions of patient safety aspects in an emergency setting. Semistructured interviews were conducted with 13 Registered Nurses from an emergency ward in a large general hospital located in northeastern Brazil. Conventional content analysis in which analysis is gained without imposing preconceived categories was used to analyze the collected data. The findings were clustered in three main categories: Barriers and facilitators for the adoption of patient safety practices, Training on patient safety issues, and Nursing role on the quality of patient safety. Nurses reported that the factors influencing patient safety include: lack of resources, hospi-
Preliminary Analysis of Lightning Warnings in and near the Rocky Mountains using U . S . National Lightning Detection Network and Electric Field Mill Data

Measurements of electrostatic field are known to provide some marginal value in lightning warning applications, above and beyond that provided by lightning locating systems (LLSs). However, when a simple electric field thres hold is used, numerous false alarms also typically occur. To date , most analysis of the utility of electrostatic field measurements in lightning warning have taken place either very close to sea l evel (e.g. Kennedy Space Center / USAF Eastern Range, Puget So und, Nanjing, China) or at fairly low altitude (northeastern Spain). These studies have all utilized measurements taken by one or more Electric field mills (EFMs). EFM networks have been installed at high altitudes in Colombia (at Medellín, 1600 m MSL, Manizales, 2000 m, and Bogotá, 2700 m), but to date, only one analysis of the contribution to lightning warning from an EFM at 16 00 m in Medellín has been published. One case of EFMs deplo yed in a moderately high-desert environment (White Sands Misile Range, NM, U.S., 1200 m MSL) showed false alarms due to bl owing dust. High-altitude environments are important in applications such as mining and recreation. High-altitude sites differ significantly from near-sea-level sites in the proximity of the thunde rstorm charge centers to the ground, and they may also differ sig nificantly in the dominant mechanisms of thunderstorm development and propagation. For example, whereas sea breezes are a m jor factor in the development of thunderstorms in coastal site s such as Kennedy Space Center, they are completely absent in highaltitude, interior continental locations. In order to augment the diversity of information available about the contribution of electrostatic field measurements to lightning warni ng applications, we have taken EFM measurements during the summer of 2015 on the roof of the Vaisala facility in Louisville, CO, U.S., at an altitude of 1640 m MSL and adjacent to the eastern slope of the Rocky Mountains. Although this site is not directly in the highest terrain, it is in a transitional area where thunderstorms can occur due to a variety of synoptic and mesoscal e forcing mechanisms but upstream of where storms often organ ize into well-defined propagating lines or mesoscale convect ive systems. This site at mid-latitudes is expected to be quite distinct from the near-equatorial Medellín. In this paper, we present our initial findings based on the EFM data, along with some pre liminary comparisons of thunderstorm behavior between the ad jacent mountains and the Vaisala facility based on U.S. Na tional Lightning Detection Network (NLDN) data, in order to make some inference about the utility of EFM measurements in the higher terrain.

Behavioural Problems of Juvenile Street Hawkers In Uyo Metropolis, Nigeria

The study sought the opinions of Faculty of Education Students of University of Uyo on the behavioural problems of juvenile street hawkers in Uyo metropolis. Five research hypotheses were formulated to guide the study. This cross-sectional survey employed multi-stage random sampling technique in selecting 200 regular undergraduate students in the Education Faculty of the University of Uyo for the study. The Juvenile Street Hawkers Opinioniare (JUVSHO) developed by the researchers was used in data collection. The hypotheses were tested using chi square statistic at p≤. 05 level of significance and appropriate degrees of freedom. Results indicate that juvenile street hawkers develop maladjusted patterns of behaviour, which in turn impair their academic, moral, social, physical, and psychological growth and development thus affecting their future negatively. Based on these findings, it was recommended that government should provide free basic education, improve workers remuneration, provide academic grants and aids to economically disadvantaged parents, and create jobs for unemployed parents, inter alia, in order to keep children from hawking under the guise of subsisting family income at the expense of their total development. Also, the implications of these findings for counselling psychologists in the school system were given.
Political Corruption in America: A Search for Definitions and a Theory, or If Political Corruption Is in the Mainstream of American Politics Why Is It Not in the Mainstream of American Politics Research?

Lack of a clear definition of political corruption has limited its systematic study by analysts of American politics. This article offers a conceptual framework with which to view corruption. A corrupt act is categorized by its four components: the donor, the favor, the public official and the payoff. For each component, propositions about perceived corrupt and noncorrupt elements can be formulated and tested. The usefulness of this scheme in analyzing attitudes about corruption is demonstrated with data from state legislators. Finally, the article suggests some future research possibilities using this scheme to compare elites and public or other groupings in the political system.
‘ Periodontal Therapy Simplified ’-with the Aid of Technical Advancements and Minimally Invasive Procedures

The success of periodontal therapy depends on proper diagnosis and treatment. The treatment outcomes are mainly influenced by clinician skills and knowledge. Minimally invasive dentistry has become popular in almost all the specialities.The aim of minimally invasive periodontal therapy is to developed an approach which will allow less manipulation of surrounding tissues than conventional procedures, while accomplishing the same objectives. This approach can be applied to non surgical periodontal procedures as well. In the present article various non surgical treatment modalities like use of LASERs and PDT (photodynamic therapy) and surgical periodontal procedures like minimally invasive surgery(MIS), Minimally invasive surgical techniques(MIST), modified MIST (M-MIST) etc are described which will guide the clinicians in performing day to day periodontal procedures like full mouth debridement, mucogingival surgeries, or esthetic management, in a minimally invasive manner.
Modelled and Resolved Turbulent Stresses around a circular cylinder using URANS , DES and DDES

Numerical flow analysis at Reynolds number 1.410and 8.010 over a circular cylinder is carried out in this work. The comparison of the pressure coefficient over the surface of circular cylinder is carried out with the experimental data for these Reynolds numbers. Comparisons of computed Reynolds stresses are carried out with experimental data for DES and DDES. For massively separated flows, the resolved stresses have much bigger contribution than modelled stresses. A comparison of the modelled and resolved stresses is made at the Re= 810 to appreciate their contribution. It is pointed that the contribution from both modelled and resolved Reynolds stresses give a better overall view of the Reynolds stresses of the flow.
Time‐varying multi‐regime models fitting by genetic algorithms

Many time series exhibit both nonlinearity and non‐stationarity. Though both features have been often taken into account separately, few attempts have been proposed for modelling them simultaneously. We consider threshold models, and present a general model allowing for different regimes both in time and in levels, where regime transitions may happen according to self‐exciting, or smoothly varying or piecewise linear threshold modelling. Since fitting such a model involves the choice of a large number of structural parameters, we propose a procedure based on genetic algorithms, evaluating models by means of a generalized identification criterion. The performance of the proposed procedure is illustrated with a simulation study and applications to some real data.
An experimental investigation of car—trailer high-speed stability

Abstract Previous work on car—trailer stability has been largely limited to theoretical studies with some reference to practical experience or accident statistics. In this study, extensive and systematic experimental investigations were carried out on a combined car—adjustable-trailer system. The influence of different trailer parameters on the system high-speed stability was examined by changing the mass, dimensions, and inertial characteristics of a fully adjustable trailer. It was found that the dominant factors affecting stability were the trailer yaw inertia, nose mass (mass distribution), and trailer axle position. The tyre pressure also affects the stability, although this effect is less significant. It is interesting to see that the trailer mass alone does not dramatically affect the high-speed stability, as this runs contrary to current guidelines relating to limits on the relative mass of the car and trailer. Experimental tests on a friction stabilizer and on car electronic stability programs demonstrate that both of these improve the high-speed stability and help to delay the onset of ‘snaking’.
Management of anemia among patients in intensive care units

Anemia is frequently encountered in critically-ill patients in the intensive care unit (ICU). Anemia may occur both at the time of admission, during treatment and after discharge from the ICU. The causes are multifactorial and include acute blood loss, blood loss from diagnostic testing and blunted red blood cell production. Blood transfusions are frequently given to patients in the ICU to treat low hemoglobin levels due to either acute blood loss or subacute anemia associated with critical illness. Although blood transfusion is a life-saving therapy, evidence suggests that it may be associated with an increased risk of morbidity and mortality. A feature of anemia of critical illness is lack of appropriate elevation of circulating erythropoietin concentrations in response to physiological stimuli. One important concern is that anemia may not be well tolerated by a critically ill patient. A number of blood conservation strategies exist that may mitigate anemia in hospital patients and limit the need for transfusion. These strategies include the use of hemostatic agents, hemoglobin substitutes and blood salvage techniques, the reduction of blood loss associated with diagnostic testing, the use of erythropoietin and the use of restrictive blood transfusion triggers. In this article we review the prevalence of anemia during critical illness specifically among patients in the ICU, and discuss the various factors that contribute to its development, the prevention and treatment of anemia by appropriate red cell transfusion and the place of erythropoietin in treatment.
