description: Experimental cross sections for $m$-fold photodetachment ($m=3-6$) of silicon anions via $K$-shell excitation and ionization were measured in the photon-energy range of 1830-1900 eV using the photon-ion merged-beams technique at a synchrotron light source. All cross sections exhibit a threshold behavior that is masked by pre-threshold resonances associated with the excitation of a $1s$ electron to higher, either partly occupied or unoccupied atomic subshells. Results from multi-configuration Dirac-Fock (MCDF) calculations agree with the experimentally derived cross sections for photo-absorption if small energy shifts are applied to the calculated resonance positions and detachment thresholds. Moreover, a systematic approach is applied for modeling the deexcitation cascades that set in after the initial creation of a $K$-shell hole. The resulting product charge-state distributions compare well with the measured ones for direct $K$-shell detachment but less well for resonant $K$-shell excitation. The present results are potentially useful for identifying silicon anions in cold plasmas such as interstellar gas clouds.

description: Abstract The main purpose of this study was to investigate academic performance characteristics of Oromia Development Association Special Boarding School (ODASBS) students. To this end, a descriptive correlational research method was employed. Purdue Academic Rating Scale (PARS) was used to gather data. One hundred ODASBS students (Male = 56, Female = 44) were selected through random sampling technique from grades 9 - 12. The academic performance characteristics of students were rated by subject-teachers of mathematics, English language, science, and social studies. Results of rating students’ academic performance characteristics showed that ODASBS students were at an excellent level in academic performance in mathematics, English, and science whereas at strong average in social studies. Out of the maximum possible rating scores, this study revealed that the academic performance characteristics rated as 45.42, 44.58, 44.76, and 36.2 for mathematics, English language, science, and social studies subjects, respectively. Result of correlation analysis showed that there was positive and significant relationship between mathematics and English language academic performances (r = 0.332, r2 = 0.11%, p < 0.01, df = n – 2 = 98). Mathematics academic performance was the leading academic performance characteristic and in no subject, ODASBS students fell under average performance. The school, social studies teachers, and students should give emphasis to social studies as equal as other subjects.

description: We demonstrate second harmonic generation in photonic crystal nanocavities fabricated in the semiconductor gallium phosphide. We observe second harmonic radiation at 750 nm with input powers of only nanowatts coupled to the cavity and conversion efficiency $P_{\rm out}/P_{\rm in, coupled}^2 = 430%/{\rm W}$. The large electronic band gap of GaP minimizes absorption loss, allowing efficient conversion. Our results are promising for integrated, low-power light sources and on-chip reduction of input power in other nonlinear processes.

description: This paper suggests that Information Communication Technologies (ICTs) constitute a key factor for promoting economic growth, especially for tourism economy-based regions. The adoption of ICTs in the tourism sector, assists the produced outcomes, introduces innovation and facilitates the shift to a knowledge-based economy. The case of the Lesvos island, in Greece, is considered. A survey is contacted, concerning the development of the tourism sector in Lesvos Island and the role of ICT-use. Data collected from both Greek and foreign tourists and were descriptively analysed. Results indicate the critical role of alternative types of tourism for the development of the tourism sector in the island, while ICT-use has the potential to extend the period of tourism

description: Applications of Reinforcement Learning (RL) in robotics are often limited by high data demand. On the other hand, approximate models are readily available in many robotics scenarios, making model-based approaches like planning a data-efficient alternative. Still, the performance of these methods suffers if the model is imprecise or wrong. In this sense, the respective strengths and weaknesses of RL and model-based planners are. In the present work, we investigate how both approaches can be integrated into one framework that combines their strengths. We introduce Learning to Execute (L2E), which leverages information contained in approximate plans to learn universal policies that are conditioned on plans. In our robotic manipulation experiments, L2E exhibits increased performance when compared to pure RL, pure planning, or baseline methods combining learning and planning.

description: Angular momentum loss requires magnetic interaction between the forming star and both the circumstellar disk and the magnetically driven outflows. In order to test these predictions many authors have investigated a rotation-disk connection in pre-main sequence objects with masses larger than about 0.4Msun. For brown dwarfs this connection was not investigated as yet because there are very few samples available. We aim to extend this investigation well down into the substellar regime for our large sample of BDs in the Orion Nebula Cluster, for which we have recently measured rotational periods. In order to investigate a rotation-disk correlation, we derived near-infrared (NIR) excesses for a sample of 732 periodic variables in the Orion Nebula Cluster with masses ranging between 1.5-0.02 Msun and whose IJHK colors are available. Circumstellar NIR excesses were derived from the Delta[I-K] index. We performed our analysis in three mass bins.We found a rotation-disk correlation in the high and intermediate mass regime, in which objects with NIR excess tend to rotate slower than objects without NIR excess. Interestingly, we found no correlation in the substellar regime. A tight correlation between the peak-to-peak (ptp) amplitude of the rotational modulation and the NIR excess was found however for all objects with available ptp values. We discuss possible scenarios which may explain the lack of rotation-disk connection in the substellar mass regime. One possible reason could be the strong dependence of the mass accretion rate on stellar mass in the investigated mass range.

Family labour supply and labour force participation decisions
Creators: name: Theeuwes, Jules J. M.
Publisher: name: University of British Columbia
Year: 2010

description: The main objective of this study is the empirical estimation of family labour force participation functions. The appropriate estimation procedure for a model involving choice among multiple discrete alternatives requires a statistical technique different from ordinary least squares. In this study I use the binomial and multinomial logit model to estimate parameters affecting the probabilities of choosing a particular labour force alternative. A theoretical contribution of this thesis to the econometric literature is the development of a procedure which, in the context of the multinomial logit model, allows one to test whether decision making is sequential or simultaneous. This procedure is applied in testing whether the family chooses simultaneously among possible alternatives or whether one partner decides first about participation and the other partner decides conditional upon the first. Using a Bayesian dicrimination technique it is found that the simultaneous decision model is more probable posteriori than the sequential model. A substantial portion of the empirical research in this study involves the estimation and comparison of family labour force participation and labour supply decisions. I attempt to discriminate statistically between the hypothesis that the parameters of supply and participation are either the same or that they are different and conclude that the hypothesis of different parameters is more probable, posteriori. In addition, the comparison of the parameters of family labour supply and labour force participation leads to interesting results, e.g., the substitution effect on both participation and supply behaviour of husband and wife. Another use of the estimated labour supply and labour force participation functions involves combining them to form unconditional labour supply functions. It is indicated that unconditional labour supply functions could be useful to evaluate the combined effect on supply and participation of a labour market policy.

description: This study was conducted with the aim of isolation of efficient keratinase producing bacteria from the soils of chicken feather and human hair-dumping places, determining optimum keratinase production conditions and partially characterizing the stability of keratinase interms of keratinase activity assay with regards to some physicochemical parameters. Inoculation of soil sample suspensions on chicken feather and human hair modified meal agar plate resulted in the growth of three keratinolytic bacterial isolates (Kf1and Kf2 from chicken feather and Kh from hair cut dumping sites). These isolates were identified as Bacillus species on the basis of their biochemical characteristics. The optimum temperature of keratinase production for all isolates was recorded at 60°C with activities of 16.2 U/ml/min, 15.5U/ml/min and 12.3 U/ml/min for isolates Kf1, Kf2 and Kh, respectively. In all cases, pH 7 was optimum for keratinase production resulting in activities corresponding to 16.4 U/ml/min, 15.1U/ml/min and 12.4/ml/min for Kf1, Kf2 and Kh, respectively. Among the various carbon sources tested, potato gave 14.3 U/ml/min, 11.3 U/ml/min and 10.1U/ml/min for isolates Kf1, Kf2, and Kh, respectively. Regarding nitrogen sources, yeast extract gave 25.2 U/ml/min, 20.5 U/ml/min and 16.37 U/ml/min for Kf1, Kf2, and Kh, respectively. Studies on the effect of pH on the activity and stability of keratinase enzyme revealed that the crude enzyme had a maximum stability at pH 7.The maximum keratinase stability time for the three isolates was found to be 48 hr with keratinase activity of 8.5 U/ml/min, 6.5 U/ml/min and 5.9 U/ml/min for Kf1, Kf2, and Kh, respectively. These results generally indicate that the keratinase obtained in this study belongs to the class of hydrolases that are active and stable at pH 7. Thus, identification of the three Bacillus isolates at a molecular level and separation and identification of the types of keratinase produced by molecular techniques is recommended.

description: The paper examines tourism in the Philippines, a South East Asian nation which has yet to reach its potential as an international destination. Conditions in the country are analysed and possible reasons for its relatively poor performance are discussed. Various barriers to development are identified, but political circumstances emerge as a key consideration whereby instability in assorted manifestations has impeded the operation of the industry, investment and policy making. While experiences of destination development are distinctive, the particular example offers insights into general processes and underlying dynamics.

description: Faraday rotation is one way to realize quantum non-demolition measurement of electron spin in quantum dots. To describe Faraday rotation, semiclassical models are typically used, based on quantized electron spin states and classical electromagnetic fields. Such treatments neglect the entanglement between electronic and photonic degrees of freedom that produce intrinsic quantum noise, limiting the ultimate sensitivity of this technique. We present a fully quantum-mechanical description of Faraday rotation, and quantify this intrinsic noise. A method for measuring the purity of a given spin state is suggested based on this analysis.

description: In this article I analyse the evolution of Ramsey Nasr (Rotterdam 1974) from neo-romantic to committed “political” poet. I particularly focus on the way he positioned himself, poetically and mediatically, during the years 2009-2013 – a period of economic crisis and social and political unrest – in his capacity of Poet Laureate of The Netherlands, a highly symbolic function. Supposed to represent the “nation”, in public lectures/performances he fully engaged in the polarised debate around the boundaries of historical and contemporary Dutchness. Being self half-allochtonous (Dutch-Palestinian) with a transcultural background, in his poetry he performed a multiple, plural, instable personal and collective identity, questioning any essentialistic and seemingly stable definition of the Dutch cultural identity, as of any other identity construction: the Christian, the Calvinist, the European etc. Nasr did not hesitate to provoke the political establishment, by topicalizing and investigating traumas in Dutch history and in contemporary society (Holocaust, multiculturalism and integration of Muslim migrants, Israeli-Palestinian conflict etc). Instead of erasing these traumas from collective memory, or turning them into museum-pieces, he stated the necessity for everyone to meditate on them in new, daring, hybridized forms.

ASSISTED-SUICIDE TOURISM: IS IT TOURISM?

Publisher: name: tourismos
Year: 2011

description: The purpose of this paper is to employ basic social psychological concepts in the interrelated fields of recreation, leisure, and tourism in an effort to examine if the medical tourism segment of assisted-suicide tourism is in fact a valid form of tourism. The comparative analysis reveals that although possessing an intrinsic motivation and an element of perceived freedom, travel for assisted-suicide is detached from the rewarding outcomes one normally receives from recreation, leisure, and tourism. Moreover, the consumption of tourism products is imparting an impression of actual tourism, whilst in reality the assisted-suicide experience is very much uninvolved in the true recreational and leisure aspects of tourism. The results of this paper are valuable for medical tourism and the tourism industry by helping both to avoid sectors that do not theoretically fit under their designations.

By combining scanning tunneling microscopic data with low energy electron diffraction we prove that the termination layer of the Ba122 systems is a remnant of the Ba layer, which exhibits a complex diversity of ordered and disordered structures. The observed surface topographies and their accompanying superstructure reflections in electron diffraction depend on the cleavage temperature. In stark contrast, Fe_(y)Se_(1-x)Te_(x) possesses only a single termination structure - that of the tetragonally ordered Se_(1-x)Te_(x) layer.

description: In this study, brewery sludge was evaluated in comparison with the recommended NP mineral fertilizer rate to elucidate a potential source of nutrients for maize crop. Randomized complete block design (RCBD) was laid out in three blocks at the experimental site. Physicochemical properties of the experimental soil and brewery sludge (BS) were evaluated in the soil laboratory. The N content of the grain and straw samples were determined using the wet digestion method. Heavy metals (Fe, Cu, Zn, Mn, Cr, Mo, Co, Pb, Se, and Cd) were extracted by DTPA extraction method and measured by atomic absorption spectrophotometer. The application of a 15 t ha-1 sludge rate showed the highest grain yield that exceeds the value recorded from NP-treated and control plots by 3.15 t ha-1 and 4.42 t ha-1, respectively. Similarly, the application of 12.5 t ha-1 sludge rate significantly increased the total nitrogen uptake of the crop (grain and straw) by 146.13% and 223.16% over the NP and control plots, respectively. There was 93.23%, 57.14%, and 76.78% higher significant difference of total nitrogen, organic carbon, and available phosphorus (mg kg-1) in BS than the composition found in experimental soil before the application of treatments, respectively. The application of sludge maintained most of the heavy metal concentrations to the level of safety for health following the recommended ranges by World Health Organizations (WHO). In conclusion, future long-term study is required to elucidate the effect of the sludge on soil biology, the chemical property of soil (pH and salinity), and pathogen contaminations on soil and crop production.

Year: 2011

description: Locals have been objects rather than drivers of rural tourism development in The Gambia and therefore have no direct benefits from tourism. This study used indepth and focus group interviews to identify and analyse the internal and external driving forces that influence rural tourism development in The Gambia. Rural tourism development in The Gambia will require a clear value position, operational excellence and strong customer relations to gain a market leadership that offers the nation a competitive advantage. The results can be used to help rural tourism stakeholders with locals at the core, to collaborate and manage this development proactively and retain revenue generated from tourism within rural communities. One suggestion made from the results of this study is to encourage locals to stage events that will lead to establish unique rural tourism experience which could in turn lead to securing a brand identity in the rural tourism marketplace.

description: While photospheric magnetic elements appear mainly as Bright Points (BPs) at the disk center and as faculae near the limb, high-resolution images reveal the coexistence of BPs and faculae over a range of heliocentric angles. This is not explained by a "hot wall" effect through vertical flux tubes, and suggests that the transition from BPs to faculae needs to be quantitatively investigated. To achieve this, we made the first recorded attempt to discriminate BPs and faculae, using a statistical classification approach based on Linear Discriminant Analysis(LDA). This paper gives a detailed description of our method, and shows its application on high-resolution images of active regions to retrieve a center-to-limb distribution of BPs and faculae. Bright "magnetic" features were detected at various disk positions by a segmentation algorithm using simultaneous G-band and continuum information. By using a selected sample of those features to represent BPs and faculae, suitable photometric parameters were identified in order to carry out LDA. We thus obtained a Center-to-Limb Variation (CLV) of the relative number of BPs and faculae, revealing the predominance of faculae at all disk positions except close to disk center (mu > 0.9). Although the present dataset suffers from limited statistics, our results are consistent with other observations of BPs and faculae at various disk positions. The retrieved CLV indicates that at high resolution, faculae are an essential constituent of active regions all across the solar disk. We speculate that the faculae near disk center as well as the BPs away from disk center are associated with inclined fields.

description: Let $D$ be an unbounded domain in $\RR^d$ with $d\geq 3$. We show that if $D$ contains an unbounded uniform domain, then the symmetric reflecting Brownian motion (RBM) on $\overline D$ is transient. Next assume that RBM $X$ on $\overline D$ is transient and let $Y$ be its time change by Revuz measure ${\bf 1}_D(x) m(x)dx$ for a strictly positive continuous integrable function $m$ on $\overline D$. We further show that if there is some $r>0$ so that $D\setminus \overline {B(0, r)}$ is an unbounded uniform domain, then $Y$ admits one and only one symmetric diffusion that genuinely extends it and admits no killings. In other words, in this case $X$ (or equivalently, $Y$) has a unique Martin boundary point at infinity.

description: The paper examines tourist perceptions and experiences through conducting survey based on the standard questionnaire. It argues that tourist perception is positive and their experiences are beyond expectations based on cultural enrichment and local people friendliness plus local hospitality facilities. The type of tourists visiting Angkor can be generally categorized as cultural tourists. Their motives and experiences are intertwined. Although tourists are satisfied with their visit, there are some concerns especially the issues of environmental pollution, sanitation and cleanliness, local poverty, and language barriers, which lead to lack of communication between tourists and local people.

description: The holographic models for dense QCD matter work surprisingly well. A general implication seems that the deconfinement phase transition dictates the maximum mass of neutron stars. The nuclear matter phase turns out to be rather stiff which, if continuously merged with nuclear matter models based on effective field theories, leads to the conclusion that neutron stars do not have quark matter cores in the light of all current astrophysical data. We comment that as the perturbative QCD results are in stark contrast with strong coupling results, any future simulations of neutron star mergers incorporating corrections beyond ideal fluid should proceed cautiously. For this purpose, we provide a model which treats nuclear and quark matter phases in a unified framework at strong coupling.

description: Nations of the South Pacific face a number of major challenges with respect to sustainable tourism development. Much of the literature presents overtly pessimistic conceptualisations of South Pacific nations as environmentally vulnerable and economically dependent. This paper argues that the narrative concerning sustainable tourism development in the South Pacific is incomplete and the predominant narrative viewing the South Pacific nations as economically and environmentally vulnerable is too simplistic. Additionally, this paper challenges the narrative that high or mass levels of tourism within the South Pacific cannot be sustainable. Based on experience derived from operational experience and consultancy, this paper provides insights into the challenges and possibilities for sustainable tourism development in the South Pacific.

description: The electromagnetic characteristics of plane-transformed invisibility cloaks are quantitatively studied in this paper. We take elliptical cylindrical cloak as the example, and use an elliptical cylindrical wave expansion method to obtain the scattered field. It is demonstrated that an ideal elliptical cylindrical cloak is inherently visible. Noticeable field scattering and penetration will be induced when the cloak is exposed directly to an electromagnetic wave. However, as long as the cloak consists of a perfect electric conducting lining at the interior surface, perfect invisibility can still be achieved along the direction parallel to the major axis of the cloak for transverse magnetic illumination. Another plane-transformed cloak with a conical geometry is also proposed. The advantage of this cloak is that all the permittivity and permeability elements are spatially invariant while none of them is singular. Hence, it is easily realizable with artificially structured metamaterials. Finally, we show that this kind of cloak can also be used to cloak objects on a flat ground plane.

Institutional-based descriptive and explanatory research designs were used in the study. Using a survey method, quantitative data were collected by structured questionnaire. Both descriptive and inferential statistical methods were used to analyze and present data. Young people in Wolaita Sodo town were found to have a high value to virginity. It is also found that 18.2% of primary school students reported that they engaged in premarital sexual practice which is lower than the rate found among the University students (33.2%). Out of the respondents who reported to have had premarital sex, 38% of primary school students and 59.8% of University students disclosed that they have sexual relationships only with a single partner whereas 20% of primary school students and 19.5% of University students reported that they have five and above life-time sex partners. In addition, primary school students have been found to be better in terms of engaging in less risky premarital sexual practices compared to their University students counterparts (59.8% to 62% in regular condom use; 56% to 55.2% in undertaking HIV testing before engaging in sexual practices, respectively). While being female (r=.181, P

Street of T’ongs: planning in Vancouver’s Chinatown
Creators: name: Young, Raymond Edgar
Publisher: name: University of British Columbia

description: Street of T'ongs is not so much a study as it is a digest, descriptive in nature, of the historical, social, and physical facets of Vancouver's Chinatown. It does not have as its purpose the proving or disproving of a selected hypothesis; rather, it attempts for the first time within both physical and social planning spheres of interest to provide a comprehensive guide to the practical planner seeking information and general data on a unique ethno-spatial community in the city. Numerous sources have been culled for relevant material which has been ordered and put together to develop a composite picture of Vancouver's Chinatown. Knowledge of many of the present problems and trends discussed, grows out of personal experience in living and working in the Chinatown area. While no formal interviews were conducted, hundreds of conversations over two years and numerous meetings with residents and professionals in the area have, provided perhaps a more balanced and broader view of local concerns and issues. This thesis shows that Vancouver's Chinatown has reached a critical stage of change in its internal social structure. Many of the pressures and issues causing in part or just concurrent with this change are, of interest and within the jurisdiction of planners at the municipal level. The enclave is opening and being shaped by internal and external forces — no longer is it as totally self-contained, sheltered, or as resistant to intrusion as has been generally understood. If planners are to responsibly and realistically help shape this change, their actions must stem from a broad base of community understanding, and community support, as well as technical expertise, that can be applied sensitively, in a manner compatible with community aspirations and civic needs.

description: In this work, we demonstrate measurements of photodestruction rates of translationally cold, charged biomolecules. The long-term stable storage of the molecular ions in an ion trap at ultra-high vacuum conditions allows measurement of small rates and verification that rates are linear in photodestruction laser intensity. Measurements were performed on singly protonated molecules of the organic compound glycyrrhetinic acid (C30H46O4), dissociated by a continuous-wave UV laser (266 nm) using different intensities. The molecules were sympathetically cooled by simultaneously trapped laser-cooled barium ions to translational temperatures of below 150 mK. Destruction rates of less than 0.05 s^-1 and a cross section of (1.1 +/- 0.1) * 10^-17 cm^2 have been determined. An extension to tunable UV laser sources would permit high-resolution dissociation spectroscopic studies on a wide variety of cold complex molecules.

TOURISM ACTIVITY AND ECONOMIC CONDITIONS IN BRITAIN
Creators: name: Apostolakis, Alexandros
name: Clark, Dave
Publisher: name: tourismos
Year: 2011

description: This study examines the impact of tourism activity on local business and economic conditions in local economies in Britain. The empirical investigation focuses on whether or not tourism activity is beneficial to local rural and urban economies and informs policy makers aiming to maximise their tourism potential. The analysis differentiates local authority areas into two distinct groups according to the intensity of tourism employment (below and above average). Whilst the empirical evidence suggests that tourism exerts positive benefits to local economies in the form of entrepreneurship, these benefits may not accrue to the tourism sector itself because in the act of “moving on” the labour force takes its improved human capital with it. This means that the promotion of tourism alone as a policy for regeneration may not be as successful as some policymakers might perceive. It is clear that a “one size fits all” prescription is inappropriate.

description: The medicinal plant, Syzygium guineense (Willd.) DC mediated green silver nanoparticles (SyG-Ag NPs) were successfully synthesized for the first time in Ethiopia. The synergistic influence of biomolecules of the plant leaf extract such as alkaloids, phenolic compounds, tannins, saponins and glycosides with Ag NPs towards the antibacterial activity has been investigated. The synthesized nanoparticles were characterized by UV-Vis, UV-DRS, FT-IR, XRD, SEM, EDXA, TEM, HRTEM and SAED techniques. The presence of absorbance maxima, λmax at 452 nm confirms the formation of SyG-Ag NPs. The energy gap, Eg of NPs, was found to be 2.1 eV. FTIR spectra confirmed the presence of biomolecules in the extract and NPs. The presence of 4 sharp peaks in the XRD pattern of NPs confirmed highly crystalline nature of NPs. The purity of the NPs was confirmed by SEM-EDAX analysis. The average particle size of NPs was found to be 27.62 nm. TEM-HRTEM-SAED analysis resulted in d-spacing values of 0.2396 nm which corresponds to Ag (111) lattice fringes of SyG-Ag NPs. The d-spacing value of the derived diffraction planes from 4 major spots; d111Ag = 0.2428 nm, d200Ag = 0.2056 nm, d220Ag = 0.1483 nm and d311Ag = 0.1263 nm, are in agreement with the XRD data. The antibacterial test results showed synergistic effect against both Gram positive bacteria, S. aureus (11±0.04 mm), and Gram negative bacteria E. coli (12±0.012 mm), P. aeruginosa (10±0.1 mm), and E. aerogenes (13±0.032 mm), respectively, proving potentiality of SyG-Ag NPs as a remedy for infectious diseases caused by tested pathogens.

Publisher: name: tourismos
Year: 2011

description: Enterprises in the tourism sector are being exposed to ever fiercer national and international competition and are confronted with difficulties in market positioning. One possibility for achieving differentiation on the market is high service quality and the creation of strong wellness brands. The aim of the present work is to investigate whether brands suggest a promise of quality that also appears to be especially important in wellness tourism. In this connection the study ascertains whether the brand awareness of wellness guests influences the perception of quality. The study also investigates whether demographic differences exist between brand aware and non-brand aware wellness guests. The results show that brands of wellness cluster are relatively weakly anchored in people's minds. There are demographic differences between brand aware and non-brand aware wellness guests. The existence of brand awareness raises the expected quality but not the perceived quality.

EXPLORING THE EFFECTS OF DESTINATION’S POSITIONING ON HOTELS’ PERFORMANCE: THE MILAN CASE
Creators: name: Sainaghi, Ruggero
Publisher: name: tourismos
Year: 2011

description: The present paper investigates the link existing between the commercial mix, seasonality of destination and daily performance of hotel businesses. The choices made at city level form a commercial mix which, despite the differing emphases and specific features of single businesses, tends to mark the entire hotel industry.The Milan case, in particular, shows the capacity of trade fair events and business components to increase average room rates and occupancy. On the other hand, there is a resulting slackening in holiday periods and non-working weeks, when a low level of the average room rate and occupancy is seen. Empirical findings suggest the central role played by metamanagement strategy. For this reason the article proposes an approach to help destination managers to reduce the seasonalities on which to focus their lines of development.

description: The interiors of high mass compact (neutron) stars may contain deconfined quark matter in a crystalline color superconducting (CCS) state. On a basis of microscopic nuclear and quark matter equations of states we explore the internal structure of such stars in general relativity. We find that their stable sequence harbors CCS quark cores with masses M_core \le (0.78-0.82)M_{sun} and radii R_core \le 7 km. The CCS quark matter can support nonaxisymmetric deformations, because of its finite shear modulus, and can generate gravitational radiation at twice the rotation frequency of the star. Assuming that the CCS core is maximally strained we compute the maximal quadrupole moment it can sustain. The characteristic strain of gravitational wave emission $h_0$ predicted by our models are compared to the upper limits obtained by the LIGO and GEO 600 detectors. The upper limits are consistent with the breaking strain of CCS matter σ\le 10^{-4} and large pairing gaps Δ\sim 50 MeV, or, alternatively, with σ\sim 10^{-3} and small pairing gaps Δ\sim 15 MeV. An observationally determined value of the characteristic strain h_0 can pin down the product σΔ^2. On the theoretical side a better understanding of the breaking strain of CCS matter will be needed to predict reliably the level of the deformation of CCS quark core from first principles.

description: Let $U_F$ be the Floquet operator of a time periodic hamiltonian $H(t)$. For each positive and discrete observable $A$ (which we call a {\em probe energy}), we derive a formula for the Laplace time average of its expectation value up to time $T$ in terms of its eigenvalues and Green functions at the circle of radius $e^{1/T}$. Some simple applications are provided which support its usefulness.
