THE INFLUENCE OF DARK MATTER HALOS ON DYNAMICAL ESTIMATES OF BLACK HOLE MASS: 10 NEW MEASUREMENTS FOR HIGH-σ EARLY-TYPE GALAXIES

Adaptive optics assisted SINFONI observations of the central regions of 10 early-type galaxies are presented. Based primarily on the SINFONI kinematics, 10 black hole (BH) masses occupying the high-mass regime of the MBH–σ relation are derived using three-integral Schwarzschild models. The effect of dark matter (DM) inclusion on the BH mass is explored. The omission of a DM halo in the model results in a higher stellar mass-to-light ratio, especially when extensive kinematic data are used in the model. However, when the diameter of the sphere of influence—computed using the BH mass derived without a dark halo—is at least 10 times the point-spread function FWHM during the observations, it is safe to exclude a DM component in the dynamical modeling, i.e., the change in BH mass is negligible. When the spatial resolution is marginal, restricting the mass-to-light ratio to the right value returns the correct MBH although a dark halo is not present in the model. Compared to the MBH–σ and MBH–L relations of McConnell et al., the 10 BHs are all more massive than expected from the luminosities and 7 BH masses are higher than expected from the stellar velocity dispersions of the host bulges. Using new fitted relations, which include the 10 galaxies, we find that the space density of the most massive BHs (MBH ≳ 109 M☉) estimated from the MBH–L relation is higher than the estimate based on the MBH–σ relation and the latter is higher than model predictions based on quasar counts, each by about an order of magnitude.
Cultural transmission and its possible effect on urban acoustic adaptation of the great tit Parus major J. Bueno-Enciso, D. Núñez-Escribano &

Cultural transmission and its possible effect on urban acoustic adaptation of the great tit Parus major. — Urban great tits (Parus major) sing with a higher minimum frequency than their forest conspecifics. Cultural processes may account at least in part for the song divergence in city birds as great tits learn their repertoire from conspecifics and switch to high pitch song types in presence of background noise. However, in small cit � ies, this process of cultural divergence could be constrained because it is likely that these birds have a greater exchange of song types with the outside. We tested this prediction by recording great tit songs in a small city (Toledo, central Spain) and in a nearby forest. We found that background noise and the peak and the maximum frequency of songs were higher in the city but the minimum frequency did not differ. The pause length was also longer in forest birds. Seventy percent of the song types were shared between Toledo and the nearby forest. These results suggest that the small size of Toledo allows a homogenized cultural wealth, preventing the devel� opment of a high pitch song as observed in larger cities.
Disturbances in a VLF radio signal prior the M=4.7 offshore Anzio (central Italy) earthquake on 22 August 2005

Abstract. On 22 August 2005 an earthquake with magnitude M=4.7 occurred in the Anzio (central Italy) offshore area. From 2002, a VLF-LF radio receiver is into operation in Bari (southern Italy). The intensity and the phase of the signals transmitted by GB (f=16 kHz, United Kingdom), FR (f=20.9 kHz, France), GE (f=23.4 kHz, Germany), IC (f=37.5 kHz, Island) and IT (f=54 kHz, Sicily, Italy) has been monitored with a 5 s sampling rate. The previous epicenter is near enough to some of the radio paths and the data collected were studied in order to reveal possible seismic effects. The raw analysis revealed a clear drop in the intensity of the FR radio signal on 19 August. Then the wavelet analysis was applied to the intensity and the phase data of the different radio signals. In the mentioned day an increase in the band 60–120 min was revealed in the spectra of the FR signal. Then the principal component analysis was applied and again the 19 August stood up as an anomalous day for the FR radio signal. The path of this signal, among the paths of the five radio signals collected by the Bari receiver, is the nearest to the mentioned epicentre and the anomaly revealed on 19 August appears as a precursor of the earthquake. This result confirms the possible precursor revealed by other researchers in the air Rn content in a site located 5 miles far from the epicenter.
Thermal Stability of DNA: DNA Hybrids within the Genus Agrobacterium

SUMMARY: Molecular hybrids were prepared between unlabelled DNA from representative strains of eleven genetic races of Agrobacterium and [14C]DNA from typical strains of each of the three main races. The thermal stability of each hybrid was determined. The nature of the hybrids formed varied with the incubation temperature and the kind of DNA used. Hybridization in 2 × SSC-30% dimethylsulphoxide below 59°C yielded two kinds of hybrids: a labile one of unknown nature, denaturing below 59°C, and a more or less stable hybrid denaturing above that temperature. The latter was the only one formed in hybridizations at or above 59°C. There were three kinds of stable hybrids. Within each of the main Agrobacterium races thermal stability of the molecular hybrid was about the same (within 2°C) as for the homo-duplex. Between two races of 50% DNA relatedness, the duplexes were about 6°C less stable. Between races of 10 to 15% DNA relatedness, the duplexes were weak, and the stability was at least 13°C lower. The stability of the hybrids decreased concomitantly with the degree of DNA relatedness. The decreased hybrid denaturation curve is not due to AT-rich sequences. The less two races of agrobacteria appeared to be evolutionarily related, the more mutations occurred within the common part.
Monitoring Pareto Type IV SRGM using SPC

The Reliability of the Software Process can be monitored efficiently using Statistical Process Control (SPC). SPC is the application of statistical techniques to control a process. SPC is a study of the best ways of describing and analyzing the data and then drawing conclusion or inferences based on available data. With the help of SPC the software development team can identify software failure process and find out actions to be taken which assures better software reliability. This paper provides a control mechanism based on the cumulative observations of Interval domain data using mean value function of Pareto type IV distribution, which is based on Non-Homogenous Poisson Process (NHPP). The unknown parameters of the model are estimated using maximum likelihood estimation approach. Besides it also presents an analysis of failure data sets at a particular point and compares Pareto Type II and Pareto Type IV models.
Managerial Competencies for Chairpersons: A Delphi study

Competencies of chairpersons in the universities have become a concern because they are in the heart of an effective academic department and their competencies influences the reputation of the university. The purpose of this article is to identify and to develop competencies needed by chairpersons. This research used Delphi’s technique in three rounds of data gathering. The benefits of this research methodology are the use of experts in obtaining opinions and ideas without time and geographical limitations. The results demonstrated 30 generic competencies with combination of cognitive, interpersonal, and intrapersonal competencies and 33 specific competencies including knowledge and skills needed by chairpersons.
SCALING RELATION IN TWO SITUATIONS OF EXTREME MERGERS

Clusters of galaxies are known to be dynamically active systems, yet X-ray studies of the low-redshift population exhibit tight scaling laws. In this work, we extend previous studies of this apparent paradox using numerical simulations of two extreme merger cases, one is a high Mach number (above 2.5) satellite merger similar to the “bullet cluster” and the other is a merger of nearly equal-mass progenitors. Creating X-ray images densely sampled in time, we construct TX, Mgas, and YX measures within R500 and compare to the calibrations of Kravtsov et al. We find that these extreme merger cases respect the scaling relations, for both intrinsic measures and for measures derived from appropriately masked, synthetic Chandra X-ray images. The masking procedure plays a critical role in the X-ray temperature calculation, while it is irrelevant in the X-ray gas mass derivation. Miscentering up to 100 kpc does not influence the result. The observationally determined radius R500 might conduce to systematic shifts in Mgas and YX, which increases the total mass scatter.
ALLELOPATHIC POTENTIAL OF COVER CROPS IN CONTROL OF SHRUBBY FALSE BUTTONWEED ( Spermacoce verticillata )

Searching for alternatives to deal with weeds without the exclusive use of herbicides can increase the sustainability of agricultural production in the Amazon region. This study aimed to evaluate the allelopathic potential of cover crops on the weed shrubby false buttonweed (Spermacoce verticillata L.). Three straw levels (1; 2.5 and 5 mg cm-2) of thirteen cover crops (Cajanus cajan, Canavalia ensiformis, Crotalaria juncea, C. ochroleuca, C. spectabilis, Mucuna aterrima, M. cinereum, Pennisetum glaucum, Sorghum bicolor, S. sudanense, Urochloa brizanha cv. Xaraés, U. brizantha cv. Piatã and U. ruziziensis) were assessed on germination and initial growth of weed and lettuce. We carried out two experiments (weed and lettuce) in a factorial scheme (cover crops x straw levels) with additional treatment (control without straw) in a completely randomized experimental design, with four replicates. The straw of the cover crops inhibited the germination and initial growth of the target plants. The highest straw levels promoted 44.0 and 78.8% reductions in radicle length in relation to the lowest dose (1 mg cm-2), for lettuce and Spermacoce verticillata, respectively. The highest sensitivity to allelochemicals occurred on the radicle. The major suppressive effects on weed germination were promoted by Cajanus cajan, Urochloa brizanha cv. Xaraés, Mucuna cinereum, M. aterrima, Canavalia ensiformis, Crotalaria juncea, C. spectabilis and U. ruziziensis. Cover crops use is an integrated practice management to control Spermacoce verticillata under no-tillage system.

SHOULD A FUNCTION CONTINUE

We show that two l-calculus terms can be observationally congruent (i.e., agree in all contexts) but their continuation-passing transforms may not be. We also show that two terms may be congruent in all untyped contexts but fail to be congruent in a language with call/cc operators, and that two terms may have the same meaning in a direct semantics but not in a continuation semantics. Hence, familiar reasoning about terms may be unsound in a setting with continuations, demonstrating the need for a theory of continuations.
To stay or not to stay? Japanese spectators’ event-related perspectives on a professional golf tournament

ABSTRACT Purpose: The purpose of this study was to examine the impact of core product features and event operations on spectators’ desire to stay at professional golf tournaments held in Japan. Design: Spectators (N = 602) completed a survey on consumer demand for core product features and consumer assessment of event operation quality during a tournament. Approach/Findings: Structural Equation Modeling (SEM) analyses revealed that three core product factors (game of golf, affection to player, and course setting) and two operational factors (event service and hospitality/amenity) significantly affected Japanese spectators’ desire to continuously stay at a professional golf tournament, which in turn affected their attendance of future tournaments. Implications: The promotion of golf tournaments with the unique characteristics of golf market demand factor may assist sport marketers in attracting and retaining their spectators. Similar studies in other types of golf tournaments and other sport contexts are suggested so as to increase the generalizability of the research findings and elevate the level of conceptualization for forming useful theories.
Pulsar emission in the very-high-energy regime

The vast majority of the pulsars detected by the Fermi Large Area Telescope (LAT) display spectra with exponential cutoffs falling in a narrow range around a few GeV. Early spectral modelling predicted spectral cutoff energies of up to 100 GeV. More modern studies estimated spectral cutoff energies in the 1-20 GeV range. It was therefore not expected that pulsars would be visible in the very-high-energy (VHE; >100 GeV) regime. The VERITAS detection (confirmed by MAGIC) of pulsed emission from the Crab pulsar up to 400 GeV (and now possibly up to 1 TeV) therefore raised important questions about our understanding of the electrodynamics and local environment of pulsars. H.E. S.S. has now detected pulsed emission from the Vela pulsar in the 20-120 GeV range, making this the second pulsar detected by a ground-based Cherenkov telescope. We will review the latest developments in VHE pulsar science, including an overview of recent observations and refinements to radiation models and magnetic field structures. This will assist us in interpreting the VHE emission detected from the Crab and Vela pulsars, and predicting the level of VHE emission expected from other pulsars, which will be very important for the upcoming CTA.
Olympic Medals, Economy, Geography and Politics from Sydney to Rio

T he paper uses Heckman model to examine the statistical importance of over 140 independent variables on the Olympic performance of all countries participating in the Summer Olympic Games from Sydney 2000 to Rio 2016. We find that countries which export more products have a higher likelihood of winning an Olympic medal than their counterparts exporting fewer products, and explain why this is the case. Statistical importance of gross domestic product per capita, labor force, average temperature and three host effects (previous host, current host, future host) is also confirmed while the role of political variables in Olympic success remains inconclusive.
Design and In Vitro Characterization of Dexlansoprazole Controlled Release Tablets

Aim: This study was to develop a controlled release formulation of various proton pump inhibitor drugs to maintain constant therapeutic levels of the drug over 24 h. Settings and Design: Dexlansoprazole was selected as model drugs. Various formulations were developed with different polymers for each drug molecule. To achieve pH-independent drug release of formu precompression blends of all formulations were subjected to various flow property tests, and all the formulations were passed the tests. Various grades of hydroxypropyl methylcellulose were employed as polymers. Statistical Analysis Used: Absence of probable chemical interactions of Fourier transform infrared between pure drug and polymers. Results: Dexlansoprazole dose was fixed as 30 mg. Total weight of the tablet was considered as 250 mg. Polymers were used in the concentration of 75 and 150 mg concentration. All the formulations were passed various physicochemical evaluation parameters and they were found to be within limits. Conclusions: Whereas from the dissolution studies it was evident that the formulation (F-2) showed better and desired drug release pattern, i.e. 98.79 ± 0.48 in 24 h. It followed zero-order release kinetics mechanism.
Asteroid Systems: Binaries, Triples, and Pairs

In the past decade, the number of known binary near-Earth asteroids has more than quadrupled and the number of known large main belt asteroids with satellites has doubled. Half a dozen triple asteroids have been discovered, and the previously unrecognized populations of asteroid pairs and small main belt binaries have been identified. The current observational evidence confirms that small ( 20 km) binaries with small satellites are most likely created during large collisions.
How do stars affect ψDM haloes

Wave dark matter, $\psi$DM, has recently been gaining attention as a dark matter candidate. This is due in part to the model's ability to predict, thus a falsifiable model. Noticeably it predicts a central prominent core, dubbed as the soliton, in every galaxy and large-amplitude density fluctuations in galaxy halos dubbed as halo granules. In this work we conduct the first $\psi$DM halo simulations that include stars in the inner halo. The results show that the soliton becomes ever stronger in the presence of stars, and the soliton slowly grows by absorbing mass from its host halo to maintain the soliton scaling relation. Moreover, halo granules become "non-isothermal" after stars have thoroughly interacted with the inner halo, a situation unlike isothermal granules in halos of pure $\psi$DM cosmological simulations. We find that the composite (dark matter$+$stars) mass density can locally follow the isothermal profile near the stellar half-light radius in most cases. Phase separation that segregates a uniform population of stars into two distinct populations of high and very low velocity dispersions stars is also found in some situations. While halo stars have high velocity dispersion, the cold component is bound inside the soliton resembling stars residing in faint dwarf spheroidal galaxies. The most striking result of this study is that the velocity dispersion of halo stars increases rapidly toward the galactic center by a factor of at least $2$ or so inside the half-light radius caused by the deepened soliton potential, a result that compares favorably with observations of elliptical galaxies and bulges in spiral galaxies. Finally, we find that the inner halo follows the same self-similar relation as the soliton does within the mass range of dwarf to small galaxies.
The construction and evaluation of a generic Work Performance Questionnaire for use with administrative and operational staff

The principal objective of the study was the construction and evaluation of a work performance questionnaire for use with administrative and operational staff. Work performance is a multidimensional construct that indicates how well a worker performs in his/her work, the degree of initiative he/she takes, the ingenuity he/she shows in the fnding of solutions for problems, and the manner in which he/she uses the human resources at his/her disposal. Two questionnaires were constructed – one for staff performing managerial functions (the full scale) and one for staff in non-managerial positions (the shortened scale). The sample consisted of 278 staff at a South African university. The full scale yielded a reliability of 0,983 and the shortened scale a reliability of 0,978. The implications of the fndings are discussed.
Status of the Mediterranean monk seal Monachus monachus in the western Sahara and the implications of a mass mortality event

The largest aggregation of the highly endangered Mediterranean monk seals Monachus monachus is located on the Cap Blanc Peninsula on the coast of the western Sahara. Photographic identification of individuals was used in a capture-recapture analysis to estimate the abundance and composition of the colony during 1993 to 1998. Results of the application of these techniques to Mediterranean monk seals were satisfactory, and allowed independent annual population estimates. No significant trends in abundance over the period 1993 to 1996 were detected, and the mean estimate for the period was 317 seals (CV = 0.16; 95% CI: 237 to 447). Environmental changes affecting suitability of habitat, particularly food availability, are suggested as major factors for limited population recovery during this period. In spring 1997, a mass mortality event reduced the population size to 109 individuals (CV = 0.14; 95% CI: 86 to 145). Mortality was age-specific and resulted in a severe change in the stage composition of the population. Adults were the most affected, and therefore the proportion of juveniles increased from an initial 12% before the event to about 29% after. As a result of both the decrease in seal numbers and the change in population composition, the number of individuals potentially contributing to reproduction fell to about 77 or fewer. This number may not be enough to maintain genetic variability and overcome the effect of demographic stochasticity. The demographic changes caused by the die-off are expected to have both positive and negative effects on the reproductive success of the colony. However, they are undoubtedly factors which potentially threaten the stability and survival of the colony in the near future.
1 Corporate heritage tourism brand attractiveness and national identity

Purpose: Examines the attractiveness of the Tong Ren Tang (TRT) as a Chinese corporate heritage tourism brand and considers the significance of TRT for Chinese national identity. The study considers the saliency of Balmer’s augmented role identity notion vis-à-vis corporate heritage institutions/corporate brands. Insights are made from and for corporate heritage, heritage tourism and national identity literatures. Design/Methodology/Approach: A conceptual model comprising five hypotheses was developed and this informed a survey-based questionnaire administered to domestic tourists/customers visiting Tong Ren Tang’s flagship shop in Beijing. Findings: The attractiveness to domestic Chinese tourists/customers of the Tong Ren Tang corporate heritage tourism brand was found to be attributable to its multiple role identities: national, corporate, temporal, familial, and imperial. As such, this study lends credence to Balmer’s augmented role identity notion. Chinese domestic tourists/customers-as members of an ethnic Chinese community-in visiting TRT not only consume an extant corporate heritage by tangible and intangible means but can also be seen to express, and reaffirm, their sense of Chinese national identity. Practical implications: For Tong Ren Tang’s (TRT) managers there should be an appreciation that the attractiveness of TRT as a corporate heritage tourism brand rests not only on what it sells but also in what it symbolises in national and cultural terms. This finding is applicable to the managers many other corporate heritage/corporate heritage tourism brands. Social implications: Adopting a primordial perspective, the TRT pharmacy was found to be of singular significance to China’s national identity. Traditional Chinese Medicine, Confucian and Daoist religious/philosophical and China’s erstwhile Imperial polity are significant and enduring precepts of Chinese national identity. As such the TRT flagship shop/brand is of singular importance since China has eviscerated much of its cultural heritage –particularly in relation to its corporate heritage brands. Originality/value: The first empirical study to focus on corporate heritage tourism brands, and one of the first studies to examine a Chinese corporate heritage/corporate heritage tourism brand. Also significant in focussing on the Tong Ren Tang corporate heritage brand. Established in 1669, TRT’s history spans five centuries: a corporate provenance which is exceptional within the People’s Republic of China. The study links the corporate brand notion with the nascent corporate heritage brand domain and the established area of heritage tourism.
