SWEET-Cat: A catalogue of parameters for Stars With ExoplanETs - I. New atmospheric parameters and masses for 48 stars with planets

Context. Thanks to the importance that the star-planet relation has to our understanding of the planet formation process, the precise determination of stellar parameters for the ever increasing number of discovered extra-solar planets is of great relevance. Furthermore, precise stellar parameters are needed to fully characterize the planet properties. It is thus important to continue the efforts to determine, in the most uniform way possible, the parameters for stars with planets as new discoveries are announced. Aims. In this paper we present new precise atmospheric parameters for a sample of 48 stars with planets. We then take the opportunity to present a new catalogue of stellar parameters for FGK and M stars with planets detected by radial velocity, transit, and astrometry programs. Methods. Stellar atmospheric parameters and masses for the 48 stars were derived assuming local thermodynamic equilibrium (LTE) and using high-resolution and high signal-to-noise spectra. The methodology used is based on the measurement of equivalent widths for a list of iron lines and making use of iron ionization and excitation equilibrium principles. For the catalogue, and whenever possible, we used parameters derived in previous works published by our team, using well-defined methodologies for the derivation of stellar atmospheric parameters. This set of parameters amounts to over 65% of all planet host stars known, including more than 90% of all stars with planets discovered through radial velocity surveys. For the remaining targets, stellar parameters were collected from the literature. Results. The stellar parameters for the 48 stars are presented and compared with previously determined literature values. For the catalogue, we compile values for the effective temperature, surface gravity, metallicity, and stellar mass for almost all the planet host stars listed in the Extrasolar Planets Encyclopaedia. This data will be updated on a continuous basis. The compiled catalogue is available online. The data can be used for statistical studies of the star-planet correlation, as well as for the derivation of consistent properties for known planets.
SUPER-EARTHS AS FAILED CORES IN ORBITAL MIGRATION TRAPS

I explore whether close-in super-Earths were formed as rocky bodies that failed to grow fast enough to become the cores of gas giants before the natal protostellar disk dispersed. I model the failed cores’ inward orbital migration in the low-mass or type I regime to stopping points at distances where the tidal interaction with the protostellar disk applies zero net torque. The three kinds of migration traps considered are those due to the dead zone's outer edge, the ice line, and the transition from accretion to starlight as the disk's main heat source. As the disk disperses, the traps move toward final positions near or just outside 1 au. Planets at this location exceeding about 3 M⊕ open a gap, decouple from their host traps, and migrate inward in the high-mass or type II regime to reach the vicinity of the star. I synthesize the population of planets that formed in this scenario, finding that a fraction of the observed super-Earths could have been failed cores. Most super-Earths that formed this way have more than 4 M⊕, so their orbits when the disks dispersed were governed by type II migration. These planets have solid cores surrounded by gaseous envelopes. Their subsequent photoevaporative mass loss is most effective for masses originally below about 6 M⊕. The failed core scenario suggests a division of the observed super-Earth mass–radius diagram into five zones according to the inferred formation history.
COST OF DEBT AND DIVIDEND POLICY: EVIDENCE FROM MENA REGION

Prior literature documents a positive relationship between dividend policy and corporate governance, and negative relationship between the quality of corporate governance and cost of debt. Therefore, we hypothesize that there is a negative relationship between cost of debt and dividend policy. Using a sample of firms from the MENA region (Middle East and North Africa), during the period between 2004 and 2008, we document a negative relationship between cost of debt and dividend policy. Our results remain robust even after controlling for various firm-specific characteristics. The main reason for this negative relationship is that dividend policy act as a substitute for corporate governance mechanisms in emerging markets. Prior literature argues that creditors take into consideration the quality of corporate governance while assessing the riskiness of the firm. High dividend payout ratio reflects proper corporate governance, which would result in a lower required rate of return by creditors, a lower cost of debt for the firm.
Give me a Sign: Unconsciously Influencing Purchase Intention throughFront-of-Pack Logos

The purpose of the present study was to investigate to what extend it would be possible to influence the purchase behaviour of consumers by presenting a front-of-pack nutrition logo. It was assumed that a nutrition logo can function as a prime, which is able to activate associated goals. Therefore two experiments were conducted. The first experiment was meant to test the ability of a new developed logo to activate an associated goal. In the second experiment participants were subliminal primed by the same logo before they had to indicate to what extent they would like to purchase several food products. Results showed that front-of-pack logos are capable of goal activation and can influence purchase intention. Furthermore, study 2 revealed that even an unfamiliar logo can provoke the same effect. These results provide new insights and opportunities for marketers and the development of effective interventions to promote healthier eating.
Towards supply chain collaboration in B2B pricing: A critical literature review and research agenda

Purpose – Research on business-to-business (B2B) pricing has been mainly focussed on the supplier’s pricing process, thus adopting traditionally an internal perspective and perceiving pricing as a profit distribution parameter rather than an opportunity for collaboration with customers. Recently, the opportunity to develop win-win, collaborative relationships in the B2B pricing process by embracing a supply chain perspective has started to attract the attention of scholars across several research streams, who have highlighted the emergence of this topic using different definitions, perspectives and methodologies. The purpose of this paper is to address the need for integrating the fragmented body of knowledge on B2B pricing toward supply chain collaboration. Design/methodology/approach – This critical literature review adopts an interdisciplinary approach, focussing on industrial marketing and operations and supply chain management areas. Findings – The authors provide a critical synthesis and discussion .
The role of oil prices in monetary policy rules: evidence from 4 major central banks

Recent movements in oil prices on international markets have generated many comments on the role that oil prices may play for Central Banks of oil-importing countries, oil price shocks being interpreted as supply shocks leading to higher inflation rates and lower economic growth. In this paper, we examine the role played by oil prices in the monetary policy strategy of 4 major Central Banks: the U.S. Federal Reserve, the ECB, the Bank of Canada and the Bank of England. Using an Ordered Probit model, we assess the reaction of each Central Bank to oil price changes and investigate a potential asymmetric response to oil price increases and decreases. Our results suggest that the role of oil price for Central Bankers may be very different depending on the objectives and the strategy of each Central Bank regarding inflation and output stabilization.
Free Primary Care in Zambia: An Impact Evaluation Using a Pooled Synthetic Control Method

We estimate the impacts of user fee removal in Zambia using a pooled synthetic control method. We find no evidence that user fee removal changed health seeking behaviours, even among the poorest. We show that these results are not attributable to the imperfect implementation of the policy. Nonetheless, our results confirm that the policy virtually eliminated medical expenditures, thereby providing financial protection to health services users. Since the poorest individuals were found to be less likely to use care and had lower expenses, ceteris paribus, the policy effect was similar to a transfer of US$2.22 per medical visit for the total sample but of only US$0.65 for the poorest people.
Visible spectroscopy of extremely young asteroid families

Context. Remotely identifying asteroid analogs of ordinary chondrites (OC) is difficult because the reflectance spectra of airless bodies can be modified by space weathering processes like micrometeorite impacts. Recently discovered extremely young asteroid families (ages ≤1 My) may not have suffered strong space weathering effects. Aims. We study extremely young asteroid families to learn about the composition of main belt asteroids and the space weathering rate Methods. Members of extremely young families were, for the first time, observed and taxonomically classified. Observations took place at the GEMINI telescopes, using the instrument GMOS. Results. The taxonomic classes found in the families are Q, Sq and S. The Q-class is the best proxy for OC materials. Conclusions. We discovered for the first time Q-type asteroids in the Main-belt. Also,asteroids with ≤1 My appear to have been only partially space weathered. These families are, therefore, very interesting targets for further observations in the near-infrared region.
Exploring Factors Influencing Satisfaction of the University Students Who Work as Private Tutors

Private Supplementary Tutoring (PST) have attracted enormous attention in recent days. Bangladesh experiences both forms of PST – formal and informal. There is a considerable amount of research based on the demand-side of PST. The tutors, who are the suppliers of PST in the market, are the center of attention in this paper. The forces that affect the satisfaction of a tutor from providing tuition have been investigated here through factor analysis and stepwise regression. Analyzing a set of tutors from University of Dhaka, tutoring environment and financial independence are found to have a positive relationship with the satisfaction level of a tutor. Transportation costs as well as disadvantageous factors of tutoring as in wasting productive time, hampering academic results, lack of recreation pull the level of satisfaction down. Tutors are thought to be self-concentrated since result and improvement of the tutees are absent from the formulation of their satisfaction. Driving a wedge of fellow feeling between tutors and tutees will enhance the quality of education.
Ensemble initialization of the oceanic component of a coupled model through bred vectors at seasonal-to-interannual timescales

Abstract. We evaluate the ensemble spread at seasonal-to-interannual timescales for two perturbation techniques implemented in the ocean component of a coupled model: (1) lagged initial conditions as commonly used for decadal predictions; (2) bred vectors as commonly used for weather and seasonal forecasting. We show that relative to an uninitialized reference simulation the implementation for bred vectors can improve the ensemble spread compared to lagged initialization at timescales from one month up to three years. As bred vectors have so far mostly been used at short timescales, we initially focus on the implementation of the bred vectors in the ocean component. We introduce a depth-dependent vertical rescaling norm, accounting for the vertical dependence of the variability, and extending the commonly used upper-ocean rescaling norm to the full water column. We further show that it is sufficient for the (sub-surface) ocean to breed temperature and salinity (i.e., scalar quantities), and rely on the governing physics to carry the temperature and salinity perturbations to the flow field. Using these bred vectors with a rescaling interval of 12 months, we initialize hindcast simulations and compare them to hindcast simulations initialized with lagged initial conditions. We quantify the ensemble spread by analyzing Talagrand diagrams and spread–error ratios. For both temperature and salinity, the lagged initialized ensemble is particularly under-dispersive for the first few months of predictable lead time. The ensemble initialized with bred vectors improves the spread for temperature and salinity for the 0–700 m and 1000–3500 m means, compared to the lagged ensemble at lead times of several months to one year. As the lead time increases to years, the differences between the two ensemble initialization techniques become more difficult to discern. While the results need to be confirmed in an initialized framework, the present analysis represents a first step towards improved ensemble generation at the transition from seasonal to interannual timescales, in particular at lead times up to one year.

Extreme AGN variability: evidence of magnetically elevated accretion?

Rapid, large amplitude variability at optical to X-ray wavelengths is now seen in an increasing number of Seyfert galaxies and luminous quasars. The variations imply a global change in accretion power, but are too rapid to be communicated by inflow through a standard thin accretion disc. Such discs are long known to have difficulty explaining the observed optical/UV emission from active galactic nuclei. Here we show that alternative models developed to explain these observations have larger scale heights and shorter inflow times. Accretion discs supported by magnetic pressure in particular are geometrically thick at all luminosities, with inflow times as short as the observed few year timescales in extreme variability events to date. Future time-resolved, multi-wavelength observations can distinguish between inflow through a geometrically thick disc as proposed here, and alternative scenarios of extreme reprocessing of a central source or instability-driven limit cycles.
Potential of wild plants as a source of bioactive compounds

The aim of this study was to determine biological activity of four wild plants: Menyanthes trifoliata L. , Centaurium erythraea Rafn. , Portulaca oleracea L. , and Acorus calamus L . The antioxidant activity was detected by ABTS, reducing power and phosphomolybdenum method, total polyphenol content with Folin – Ciocalteu reagent, flavonoids content by aluminium chloride method and total phenolic acid content by Arnova reagent. The detection of antimicrobial activity was carried out by disc diffusion method against three species of Gram-negative bacteria: Escherichia coli CCM 3988, Salmonella enterica subsp. enterica CCM 3807, Pseudomonas aeruginosa CCM1960 and two Gram-positive bacteria: Bacillus thuringiensis CCM 19, Stapylococcus aureus subsp. aureus CCM 2461. Results showed that wild plants are rich for biologically active substances and can be used more in different kind of industry as a cheap source of these substances. The highest antioxidant activity by ABTS and reducing power method was determined in the sample of Menyanthes trifoliata L. (64.99 mg TEAC – Trolox equivalent antioxidant capacity per g of sample and 69.05 mg TEAG per g) and by phosphomolybdenum method in the sample of Menyanthes trifoliata L. (237.97 mg TEAC per g of sample). In the sample of Menyanthes trifoliata L. was measured the highest content of total polyphenols (27.91 mg GAE – gallic acid equivalent per g of sample), flavonoids (35.69 mg QE – quercetin equivalent per g of sample) and total phenolic acids (22.56 mg CAE – caffeic acid equivalent per g of sample). All samples also showed antimicrobial activity to inhibit selected kind bacteria with the best results in Menyanthes trifoliata L.
Response of non-native lake trout (Salvelinus namaycush) to 15 years of harvest in Yellowstone Lake, Yellowstone National Park

Introduced lake trout (Salvelinus namaycush) threaten to extirpate native Yellowstone cutthroat trout (Oncorhyn- chus clarkii bouvieri) in the 34 000 ha Yellowstone Lake in Yellowstone National Park, USA. Suppression (and eventual eradication) of the lake trout population is deemed necessary for the conservation of Yellowstone cutthroat trout. A US Na- tional Park Service gill-netting program removed nearly 450 000 lake trout from Yellowstone Lake from 1995 through 2009. We examined temporal variation in individual growth, body condition, length and age at maturity, fecundity, mortality, and population models to assess the efficacy of the lake trout suppression program. Population metrics did not indicate over- harvest despite more than a decade of fish removal. The current rate of population growth is positive; however, it is lower than it would be in the absence of lake trout suppression. Fishing effort needs to increase above observed levels to reduce population growth rate below replacement. Additionally, high sensitivity of population growth rate to reproductive vital rates indicates that increasing fishing mortality for sexually mature lake trout may increase the effectiveness of suppression. Lake trout suppression in Yellowstone Lake illustrates the complexities of trying to remove an apex predator to restore a relatively large remote lentic ecosystem with a simple fish assemblage.

The IAT Is Dead, Long Live the IAT: Context-Sensitive Measures of Implicit Attitudes Are Indispensable to Social and Political Psychology

The implicit association test (IAT) is one of several measures of implicit attitudes, but it has attracted especially intense criticism. Some methodological objections are valid, but they are damning only if one accepts false analogies between the IAT and measures of intellectual aptitude, clinical diagnosis, or physical height. Other objections are predicated on misconceptions of the nature of attitudes (which are context-sensitive and reflect personal and cultural forces) or the naive assumption that people cannot be biased against their own group. Other criticisms are ideological, pertaining to questions of moral and political value, such as whether it is good to have fewer pro-White/anti-Black implicit attitudes and to provide respondents with feedback about their implicit attitudes. Implicit-attitude measures have been extremely useful in predicting voting and other political behavior. An indirect, unobtrusive, context-sensitive measure of attitudes is far more useful to social and political psychologists than an IQ test or clinical “diagnosis” would be, insofar as it reflects a dynamic Lewinian conception of the “person in the situation. ”
Affective Damage to Oral Corrective Feedback among Students in Libyan Secondary Schools

This study was carried to investigate how the learners in EFL classes emotionally react to the corrective feedback process in classroom settings and how it can affect their motivation towards the target language. For collecting the data a questionnaire was designed with ten questions and distributed among the students studying at secondary schools in Misurata, Libya. Responses to 110 valid questionnaires were analyzed. This paper first reviews the controversial role of corrective feedback in SL classrooms. Then the findings are reported and discussed. The findings show that affective damage is caused to the students, in different ways, in EFL classrooms, during the corrective feedback process. It has also found evidence that oral corrective feedback can affect the attitudes of the learners in a negative way. This paper highlights this negative aspect of the corrective feedback.
Enhancing Faculty Performance through Coaching: Targeted, Individualized Support

Coaching in higher education is a relatively new field; although, it has been taking place in educational institutions for some time, even if it was not labeled as such. This paper describes the faculty development filosophies of a US-based higher education institution with a strong culture of supporting faculty and promoting social change. A coaching model was implemented as a means for professional development. It was designed to be facilitated through a peer relationship and it offers problem-focused, contextualized opportunities for faculty to collaborate, thus making the experience and outcome more meaningful. The coaching model is individualized, confidential, non-evaluative, and incorporates three pathways to support the professional development needs of faculty: selfassigned, a request from college leadership as a means to support faculty in an identified area of need, or the New Faculty Orientation (NFO) instructor may recommend a faculty member for coaching as a way to further engage in topics not discussed in-depth in NFO.
