Hot bottom burning and s-process nucleosynthesis in massive AGB stars at the beginning of the thermally-pulsing phase

We report the first spectroscopic identification of massive Galactic asymptotic giant branch (AGB) stars at the beginning of the thermal pulse (TP) phase. These stars are the most Li-rich massive AGBs found to date, super Li-rich AGBs with log e (Li) ∼ 3−4. The high Li overabundances are accompanied by weak or no s-process element (i.e. Rb and Zr) enhancements. A comparison of our observations with the most recent hot bottom burning (HBB) and s-process nucleosynthesis models confirms that HBB is strongly activated during the fi rst TPs but the 22 Ne neutron source needs many more TP and third dredge-up episodes to produce enough Rb at the stellar surface. We also show that the short-lived element Tc, usually used as an indicator of AGB genuineness, is not detected in massive AGBs, which is in agreement with the theoretical predictions when the 22 Ne neutron source dominates the s-process nucleosynthesis.
Collocation and Least Residuals Method and Its Applications

The collocation and least residuals (CLR) method combines the methods of collocations (CM) and least residuals. Unlike the CM, in the CLR method an approximate solution of the problem is found from an overdetermined system of linear algebraic equations (SLAE). The solution of this system is sought under the requirement of minimizing a functional involving the residuals of all its equations. On the one hand, this added complication of the numerical algorithm expands the capabilities of the CM for solving boundary value problems with singularities. On the other hand, the CLR method inherits to a considerable extent some convenient features of the CM. In the present paper, the CLR capabilities are illustrated on benchmark problems for 2D and 3D Navier–Stokes equations, the modeling of the laser welding of metal plates of similar and different metals, problems investigating strength of loaded parts made of composite materials, boundary-value problems for hyperbolic equations.
A STUDY OF MORPHOLOGICAL VARIATIONS AND THEIR RELATIONSHIP WITH FLOWER YIELD AND YIELD COMPONENTS IN ROSA DAMASCENA

Rosa damascena has attracted considerable attention in horticulture, biochemistry and in pharmacology because of the fragrance of the flowers and the high content of its biologically active substances. There is limited information available on factors controlling flower yield and its components. The present study reports an investigation on flower yield and the various factors affecting it, in Iranian Rosa damascena using sixteen genotypes collected from different regions in Iran. These genotypes were planted at Isfahan Agriculture Research Center, using a randomized complete block design with three replications in 2005. Twelve yield determining characters including flower yield per plant, number of flowers per plant, fresh flower weight, plant height, canopy diameter, length and width of bud, number of petal per flower, length and width of receptacle, fresh weight of petal as well as flowering period were recorded. Rosa damascena genotypes significantly varied for all the traits except for the fresh weight of petals per flower. Phenotypic and genotypic coefficients of variation for flower yield per plant (48.03%, 36.49%), number of flowers per plant (40.65%, 26.99%), number of petals per flower (37.56%, 32.31%) were higher than the coefficients for other tested traits. Cluster analysis revealed that Khuzestan and Shiraz 2 genotypes were the most related ones, while the most independent ones were the western and eastern Azerbaijan genotypes. Results of stepwise regression analysis showed that 90 percent of total variation of flower yield per plant could be explained by the number of flowers per plant. This suggested that number of flowers per plant is the most important component determining flower yield per plant. According to principle component analysis, parents with a high standing of the following traits: fresh weight of flower, number of petals per flower and bud width, may well be employed for hybridization in a breeding program. Regression and cluster analyses proved to be the appropriate multivariate analyses for an identification of Rosa damascena genotypes possessing the desirable characters for hybridization to develop improved cultivars.
How do novice business coaches identify the boundary between coaching and counselling

The coaching/counselling boundary is much talked about and yet there has been little research into how novice coaches identify the boundary in practice. This article explores how novice business coaches attempt to identify the boundary in their practice. The research employs a constructivist grounded theory approach, with seven novice business coaches and four coach supervisors. Findings suggest a theoretical framework consisting of three broad categories, each with several sub-themes, including the emotional current, gaining knowledge and abilities and defining the boundary. They also highlight some of the key challenges experienced by novice coaches.
Tilburg University Static vs Dynamic Auctions with Ambiguity Averse

This paper presents the outcome of a dynamic price-descending auction when the distribution of the private values is uncertain and bidders exhibit ambiguity aversion. In contrast to sealed-bid auctions, in open auctions the bidders get information about the other bidders’ private values and may therefore update their beliefs on the distribution of the values. The bidders have smooth ambiguity preferences and update their priors using consequentialist Bayesian updating. It is shown that ambiguity aversion usually affects bidding behavior the same way risk aversion does, but the main result is that this is not the case for continuous price descending auctions. This is new among a few theoretical cases where ambiguity aversion does not reinforce the risk aversion implications.

Gradual evolution of the Early Cretaceous marine gastropod Rissoina lineage in Central Poland

The evolutionary changes of the Early Cretaceous (Valanginian) marine gastropod Rissoina (Buvignieria) sp. from Wąwal (central Poland) show a pattern typical of the Ancient Lake Concept. Its morphology is stable during period of un− stable conditions and starts to change gradually when the environment becomes stable. The linear character of the evolu− tionary changes of Rissoina sp. and lack of evolution among co−occuring gastropods suggests that the rate of evolution was controlled by intrinsic factors, not the environment.
Behavioral Causes of the Bullwhip Effect: Multinational vs. Local Supermarket Retailers

Managers’ perception of extra days of product ordering characterises behavioral causes of the bullwhip effect that is not yet addressed so far in literature. The study therefore investigates and compares behavioral causes of the bullwhip effect within- and between multinational and local supermarkets in a three-echelon retail chain. Retail chain stock replenishment practices embodied in a survey was distributed to managers of supplier firms, wholesale distribution centres and small retail stores in Indonesia. The data was analysed using ANOVA and post-hoc test. Results show a significant mean difference in extra days of ordering for both MSCs and LSCs. The small retail stores’ perceived extra days of ordering are significantly more than what the supplier firms order upstream. Wholesale DC of both chains experiences no such effect. The study helps managers to deepen their understanding of extra days of ordering practice that is likely to be influenced by human behavior leading to the very bullwhip effect. Further, realising its negative impact on the chain performance, they need to carefully orchestrate their extra ordering practices.

The Challenges of Gaming for Democratic Education: The Case of iCivics

Video games are the most recent technological advancement to be viewed as an educational panacea and a force for democracy. However, this medium has particular affordances and constraints as a tool for democratic education in educational environments. This paper presents results from a study of the design and content of four iCivics games and their potential to meet the goals of democratic education. Specifically, we focus on the games as designed experiences, the nature and accuracy of the content, and the nature of intellectual engagement in the games. We find that the games, while easily accessible and aligned with standardized curriculum, do not provide opportunities to engage players in deliberative decision making on contemporary issues or to apply concepts from the game world to their role as citizens in training. Further, the game content is more “textbook” than the potentially dynamic and authentic types of civic engagement the medium of games can provide.
Spin in Compton scattering with pronounced polarization dynamics

We theoretically investigate a scattering configuration in Compton scattering, in which the orientation of the electron spin is reversed and simultaneously, the photon polarization changes from linear polarization into circular polarization. The intrinsic angular momentum of electron and photon are computed along the coincident propagation direction of the incoming and outgoing photon. We find that this intrinsic angular momentum is not conserved in the considered scattering process. We also discuss the generation of entanglement for the considered scattering setup and present an angle dependent investigation of the corresponding differential cross section, Stokes parameters and spin expectation.
Characterization of two lactic acid bacteria and their influence on silage fermentation of napiergrass.

Received: Revised: Accepted: June 20, 2013 October 09, 2013 October 10, 2013 Enterococcus faecium R5-1 (EF) and Lactobacillus plantarum N30-6 (LP) isolated from silages were identified and their influence on silage fermentation of napiergrass (Pennisetum purpureum Sch.) harvested at various times of sunny day were studied. Strain LP had stronger growth ability, acid tolerating capacity and wider fermentable carbohydrates than strain EF. Napiergrass was cut at 0800, 1300 and 1800 h on a sunny day and inoculated with strains EF and LP at 5 log cfu g. The concentrations of dry matter, water soluble carbohydrates and the ratio of lactic acid to acetic acid (LA/AA) were higher (P<0.05) and ammonia-N (NH3-N), acetic acid concentrations and silage pH were lower (P<0.05) for uninoculated silages made of napiergrass cut at 1300 and 1800 h compared with that cut at 0800 h. Silage inoculated with LP and EF had lower (P<0.05) NH3-N and acetic acid concentrations and higher (P<0.05) LA/AA than uninoculated silage made with napiergrass cut at 1300 and 1800 h. The EF-inoculated could not improve fermentation quality of silage made with napiergrass cut at 0800 h, which had higher (P<0.05) NH3-N and acetic acid concentrations than uninoculated silage. In conclusion, delayed cutting napiergrass at end of a sunny day was associated with better fermentation quality, and the silages inoculated with EF or LP further improved fermentation quality. ©2013 PVJ.

Knowledge Management System and Financial Performance: how this relation has been measured?

This paper compiles the latest knowledge management (KM) studies that had financial performance correlated in the last years, shows main financial indicators used and provides insights and rich context to deepen evaluation. The method adopted was a Systematic Literature Review (SLR) on studies published from 2009 to May 2015. Many topics were analised in the selected papers of this research. Firstly, KM practices found were categorized according to Ho (2009). Secondly, the financial indicators used were compared to indicators identified by Shook (2005). Thirdly, the most frequently measures used in the relationship between KM practices and financial performance were identified. Finally, we highlighted the most used methods to evaluate impact of KM in FP, evaluation of number of Publications per year and evaluation of Authors, Publishers. The paper finds that in despite of increasing number of publications correlating both topics the effects of KM in financial performance has to be more explored. However, majority of paper reports certain improvement in financial performance of companies that strongly support KM.

The Impact of Total Quality Management Practice on Employees’ Satisfaction and Performance: The Case of Mass Media’s Employees

This study attempts to investigate the impact of Total Quality Management Practice on employees’ satisfaction and performance of mass media employees. Using 155 respondents as sample that has been chosen using proportionate simple random sampling, a survey method is employed to obtain information required to conduct the study. In the end, the information obtained through survey is analysed using structural equation modeling. The results revealed that Total Quality Management has a positive and significant impact on employees’ performance, the employees’ satisfaction has a positive and significant impact on employees’ performance. It can be concluded that when one satisfies with their job, one also has a good work performance and, an outstanding performance is also caused by a well-practiced of Total Quality Management
Incentives and managerial effort under competitive pressure : an experiment

We investigate how increased competition affects firm owners’ incentives and managers’efforts in a laboratory experiment. Each owner offers a compensation scheme to his manager in two different conditions: under monopoly and under Cournot duopoly. After accepting the compensation, the manager chooses an effort level to increase the probability of a cost-reduction which affects the firm’s profit. According to standard theoretical predictions the entry of a rival firm in a monopolistic industry affects negatively both the incentive compensation and the effort level. Our experimental findings show that the entry of a rival firm has two effects on managerial effort: an internalization effect which affects positively the level of effort and an income effect which has anegative impact on effort. The combined outcome of these two effects is neutral with respect to managerial effort: we observe that when competition reduces the firm’s profit, the owner reacts by offering lower incentives but despite the lower incentives the manager still accepts the contract offer and exerts the same level of effort as under the monopoly condition.

Star formation properties of galaxies in a deep HST spectral imaging survey

In this work we evaluate the SFR from different star formation indicators in order to determine the best correction for dust extinction on a sample of star forming galaxies at tt [0,7-1,5]. The sample is composed by 87 sources detected at far-IR wavelenghts by the Herschel Space telescope (from the PEP survey), with a strong Hd emission in the near-IR 3D-UST stifless spectre.
Arctic warming and your weather: public belief in the connection

Will Arctic warming affect mid‐latitude weather? Many researchers think so, and have addressed this question through scientific articles and news media. Much of the public accepts such a connection as well. Across three New Hampshire surveys with more than 1500 interviews, 60% of respondents say they think future Arctic warming would have major effects on their weather. Arctic/weather responses changed little after Superstorm Sandy brushed the region, but exhibit consistently strong partisan divisions that grow wider with education. Belief in an Arctic/weather connection also varies, in a nonlinear pattern, with the temperature anomaly around day of interview. Interviewed on unseasonably warm or cool days, respondents are more likely to think that Arctic warming would have major effects on their weather. This unscientific response seems to mirror the scientific discussion about extremes.
Wage Incentive Profiles in Dual Labor Markets

We propose a modified version of the Shapiro-Stiglitz’s (1984) efficiency wage model by introducing temporary contracts in the standard setup. New theoretical insights emerge on the incentive problem faced by workers and firms. We argue that the existence of temporary contracts broaden the incentive menu available to employers and that the optimal incentive structure can be sustained as an equi- librium outcome only if permanent contracts do not disappear. We also provide an alternative explanation of the wage penalty suffered by temporary workers even if standard models of efficiency wages would predict higher compensations for workers facing a higher job loss risk.
An Agronomic and Profitability Study on Rice Production: A Case of Jalgaon Village of Comilla District, Bangladesh

Performance of rice crops in farmers’ fields largely lower than varietal potential. Besides, profitability is an important aspect of production decision for the semi-subsistence farming system in Bangladesh. Therefore, this study was conducted evaluate crops management practice and performance of rice in different seasons. Farmers’ group discussion with key informant farmers was conducted for collecting and validating the data using a semi-structured questionnaire. Adoption of modern rice varieties was high in the village. Rice is planted delay in all the seasons because of three crops (rice-rice-rice) rice based cropping patterns in the village. Farmers mainly relied on household seeds (owned stored and purchase from neighboring farmers) in Aus and Aman seasons while the dealer supplied seed is the prime seed source in Boro season. The seed rates were largely higher than recommendation rates. Farmers’ fertilizers management is highly inconsistent with recommendation practice. Both manual and chemical methods are used for controlling weeds. Chemical method is mainly practiced for controlling insects and diseases of crops. Paddle and power thresher is used for threshing rice. Boro rice gave Boro rice gave higher yield (4.94 t/ha) followed by T. Aman (3.29 t/ha) and Aus (3.09 t/ha) due to better cropping environment, good management practices, higher inputs and usages of better genotypes. The performance of rice in the three seasons showed large yield gap. T. Aman gave higher gross margin (BDT 22,015/ha) followed by Boro (BDT 16,468/ha) and Aus (BDT 9,414/ha) because of higher price and lower production cost. Participation of women in the intercultural operations of crops and their role sin decision making about farming was a few. Nevertheless, they intensively participate in post-harvest processing of crops and other household activates and decisions. In short, despite a large yield gap, rice production is profitable in the three seasons at survey year’s price. The poorer access to extension service, good quality seed, phosphorous fertilizers, pesticides and power supply were identified as barrier to achieve potential performance of rice cultivars and expected level of returns. Thus, policy supports for increasing access to extension supports and quality inputs may reduce yield gap and enhance productivity and profitability of rice crops largely.
Economic Impact of the Informal Childcare Sector in Kansas

The informal childcare sector provides a significant proportion of childcare in the U.S. However, because informal sectors are not captured in our national income accounting sys-tem, the value to our economy is largely unknown. This study examines the size of the infor-mal childcare sector in the state of Kansas. Using IMPLAN data we also calculate implicit multipliers for the sector in order to estimate the full economic effects of informal childcare on the economy of Kansas and its regions. We find that the informal childcare sector creates large economic effects compared to the formal childcare sector. More specifically, the study estimates that informal childcare created about 128,494 direct jobs within the sector, another 6,842 jobs in other sectors, and $971.5 million in total value added in Kansas in 2005. We found that families in non-metro areas are more likely to use informal childcare than those in metro areas. As a result, even though the non-metro multipliers are smaller than those of met-ro areas, the informal childcare sector generates larger economic effects in non-metro areas than metro areas in general.
Mass tracking for chemical analysis: the causes of ozone formation in southern Ontario during BAQS-Met 2007

Abstract. A three-level nested regional air pollution model has been used to study the processes leading to high ozone concentrations in the southern Great Lakes region of North America. The highest resolution simulations show that complex interactions between the lake-breeze circulation and the synoptic flow lead to significant enhancements in the photochemical production and transport of ozone at the local scale. Mass tracking of individual model processes show that Lakes Erie and St. Clair frequently act as photochemical ozone production regions, with average mid-day production rates of up to 3 ppbv per hour. Enhanced ozone levels are evident over these two lakes in 23-day-average surface ozone fields. Analysis of other model fields and aircraft measurements suggests that vertical circulation enhances ozone levels at altitudes up to 1500 m over Lake St. Clair, whereas subsidence enhances ozone over Lake Erie in a shallow layer only 250 m deep. Mass tracking of model transport shows that lake-breeze surface convergence zones combined with the synoptic flow can then carry ozone and its precursors hundreds of kilometers from these source areas, in narrow, elongated features. Comparison with surface mesonet ozone observations confirm the presence, magnitude, and timing of these features, which can create local ozone enhancements on the order of 30 ppbv above the regional ozone levels. Sensitivity analyses of model-predicted ozone and HOx concentrations show that most of the region is VOC-limited, and that the secondary oxidation pathways of aromatic hydrocarbons have a key role in setting the region's ozone and HOx levels.
