description: Cooperation is one of the foundations of human society. Many solutions to cooperation problems have been developed and culturally transmitted across generations. Because immigration can play a role in nourishing or disrupting cooperation in societies, we must understand how the newcomers' culture interacts with the hosting culture. Here, we investigate the effect of different acculturation settings on the evolution of cooperation in spatial public goods games with the immigration of defectors and efficient cooperators. Here, immigrants may be socially influenced, or not, by the native culture according to four acculturation settings: integration, where immigrants imitate both immigrants and natives; marginalization, where immigrants do not imitate either natives or other immigrants; assimilation, where immigrants only imitate natives; and separation, where immigrants only imitate other immigrants. We found that cooperation is greatly facilitated and reaches a peak for moderate values of the migration rate under any acculturation setting. Most interestingly, we found that the main acculturation factor driving the highest levels of cooperation is that immigrants do not avoid social influence from their fellow immigrants. We also show that integration may not promote the highest level of native cooperation if the benefit of cooperation is low.

description: Reinforcement Learning Algorithms (RLA) are useful machine learning tools to understand how decision makers react to signals. It is known that RLA converge towards the pure Nash Equilibria (NE) of finite congestion games and more generally, finite potential games. For finite congestion games, only separable cost functions are considered. However, non-separable costs, which depend on the choices of all players instead of only those choosing the same resource, may be relevant in some circumstances, like in smart charging games. In this paper, finite congestion games with non-separable costs are shown to have an ordinal potential function, leading to the existence of an action-dependent continuous potential function. The convergence of a synchronous RLA towards the pure NE is then extended to this more general class of congestion games. Finally, a smart charging game is designed for illustrating convergence of such learning algorithms.

description: This study aims to determine how the airline companies perceive the competition environment they are in, which competitive strategies they implement and to find out how and by which factors they are affected while forming these strategies. Qualitative research method was used in the study. The population of the study consists of the airline companies which have mainly local capital, the management centres of which are in Turkey and which have the licence of scheduled and non-scheduled domestic and international flights. A descriptive analysis was made for the data. The result of the study reveals that the competitive strategies implemented especially focus on obtaining the cost leadership. In addition, costs, customer satisfaction and service quality, employees, innovation and technological changes appear to be the most important elements among the factors which affect the competitive strategies.

description: ULK4 is an established candidate gene for mental disorders and antipsychotic treatment response. We investigated the association of functional genetic variation at the ULK4 locus with the human extended dopaminergic reward system using fMRI during the performance of a well-established reward paradigm. Two hundred and thirty-four patients were included in this study. Association of genetic variation in the ULK4 gene with reward system functioning were determined using the Desire-Reason-Dilemma (DRD) paradigm which allows to assess brain activation in response to conditioned reward stimuli. Variant prioritisation revealed the strongest functional signatures for the ULK4 variant rs17215589, coding for amino acid exchange Ala715Thr. For rs17215589 minor allele carriers, we detected increased activation responses to conditioned reward stimuli in the ventral tegmental area, nucleus accumbens and several cortical brain regions of the extended reward system. Our findings provide further evidence in humans that genetic variation in ULK4 may increase the vulnerability to mental disorders, by modulating the extended reward system function. Future studies are needed to confirm the modulation of the extended reward system by ULK4 and to specify the role of this mechanism in the pathogenesis of psychiatric disorders.

Publisher: name: tourismos
Year: 2012

description: This dissertation presents a heuristic algorithm that improves the coastal network in the Greek Aegean Sea. The Greek coastal shipping - except for its specific role for Greek tourism - becomes of utmost importance after the decision of the European Union to reinforce, for special reasons, the short-distance shipping. This dissertation suggests and describes a methodology for the re-planning of the coastal network of Greece and aims to develop a new model of the coastal shipping network in Greece. This model is documented by the heuristic algorithm for improvement, the NAUTILUS. This algorithm drastically improves the travel times for the Aegean destinations and poses the terms and conditions for the materialisation of a Complete Decision System, for the overall improvement of the Greek coastal shipping.

description: We present the final data from the spectroscopic survey of the ROSAT-ESO Flux-Limited X-ray (REFLEX) catalog of galaxy clusters. The REFLEX survey covers 4.24 steradians (34% of the entire sky) below a declination of 2.5 deg and at high Galactic latitude (|b| > 20 deg). The REFLEX catalog includes 447 entries with a median redshift of 0.08 and is better than 90% complete to a limiting flux fx = 3x10^{-12} erg s^{-1} cm^{-2} (0.1 to 2.4 keV), representing the largest statistically homogeneous sample of clusters drawn from the ROSAT All-Sky Survey (RASS) to date. Here we describe the details of the spectroscopic observations carried out at the ESO 1.5 m, 2.2 m, and 3.6 m telescopes, as well as the data reduction and redshift measurement techniques. The spectra typically cover the wavelength range 3600-7500 A at a FWHM resolution of ~14 A, and the measured redshifts have a total rms error of ~100 km s^{-1}. In total we present 1406 new galaxy redshifts in 192 clusters, most of which previously did not have any redshift measured. Finally, the luminosity/redshift distributions of the cluster sample and a comparison to the no-evolution expectations from the cluster X-ray luminosity function are presented.

Production and perception of phonemic vowel duration in French
Creators: name: Duncan, Elizabeth D.
Publisher: name: University of British Columbia
Year: 2010

description: The present study consists of two experiments which examine the use of Vowel duration in French in such word pairs as "maître:mettre" and "pâte:patte". The first experiment examines the use of vowel duration from the point of view of production. Subjects recorded sentences containing the words under study both in (unemphatically) stressed and unstressed position. Significant differences in vowel duration were found between the "long" and the "short" members of the pairs. No significant differences in vowel duration were found between the /ɑ:/:/a/ "long"."short" vowel ratios and the /ε:/:/ε/ vowel ratios. Vowel ratios were slightly smaller when words appeared in unstressed position than in stressed position but these differences were not found to be significant. Speakers from the Midi were observed to make the length distinction less frequently than speakers from other areas. The second experiment examines the use of vowel duration by the same group of native speakers in distinguishing perceptually between members of such pairs as those mentioned above. Using a small computer, vowels of the "long" and "short" members of a pair were shortened and lengthened respectively in steps of approximately 16 msec. Subjects were asked to assign a lexical value to the stimuli so obtained. Subjects' responses were found to be influenced by shifts in vowel duration. Lengthening the "short" vowel had a greater effect in reversing listener judgment of the word than did shortening the "long" vowel. When members of a pair were accompanied by a marked difference in vowel quality, shortening the "long" vowel had relatively little effect on the listeners' judgment of the word. It thus appears that for the group of speaker/listeners selected, length does play a role in distinguishing, both productively and perceptually, between such pairs as "maître:mettre" and "pâte:patte".
IS ‘MALAYSIA TRULY ASIA’? FORECASTING TOURISM DEMAND FROM ASEAN USING SARIMA APPROACH

description: Malaysia is well-known for her ‘blue’ and ‘green’ tourism attractions. Malaysian government launched several tourism programs to encourage and attract international tourist arrivals into Malaysia. This study therefore attempts to forecast the tourism demand for Malaysia from ASEAN countries. The literature on forecasting tourism demand is huge comprising various types of empirical analysis. Some of the researchers applied cross-sectional data, but most of the tourism demand forecasting used pure time-series analytical models. One of the important time-series modelling used in tourism forecasting is ARIMA modelling. This study employs quarterly time series data of ASEAN tourist arrivals to Malaysia for the period from 1995:Q1 to 2009:Q4 to forecast future tourism demand for Malaysia. The forecasting performance is based on seasonal ARIMA model. The findings of this study revealed that seasonality model does not offer any valuable insights or provide reliable forecasts on tourism demand for Malaysia by ASEAN countries. This scenario occurs because of the fact that ‘Malaysia is Truly Asia’.

description: Abstract

This study examines the impact of delamination on shear stresses in bonded joints subjected to mechanical loads. The paper examines how different types and widths of delamination affect shear stress distribution in both the xz and zz planes, focusing on two common adhesive bonding configurations, simple overlap joints and end-to-end overlap joints. There is a notable increase in stress concentration as delamination width expands, according to experimental and simulated analyses. Longitudinal delamination also affects shear stresses, though to a lesser extent than transverse delamination. Maximum stress concentrations were observed in the presence of combined longitudinal and transverse delamination in the zz plane peeling stress, which is particularly sensitive to delamination effects. The study underscores the importance of considering delamination in the design and evaluation of bonded assemblies, highlighting how variations in delamination width and type can substantially impact structural performance. The study emphasizes how differences in delamination breadth and type can significantly effect structural performance, underscoring the need of taking delamination into account in the design and evaluation of bonded assemblies.

description: In the context of transport electrification, a model coupling Electric Vehicles (EV) driving and charging decisions is considered. While a Traffic Assignment Problem (TAP) is considered for the driving part, the charging operation is done with an exact load flow on a simple distribution network. This setting allows assessing precisely the coupled impact of driving and charging decisions. In particular, to schedule the charging need coming from the driving part, different charging strategies are defined and compared according to a cost metric based on the load flow computation. In view of this metric, the proposed non-load flow based strategies can perform similarly to a load flow based one, and with significantly reduced computation time and data need. Numerical simulations show how a transportation toll can influence the charging results.

description: We describe a method for comparing the frequency spectra of oscillating stars. We focus on solar-like oscillations, in which mode frequencies generally follow a regular pattern. On the basis that oscillation frequencies of similar stars scale homologously, we show how to display two stars on a single echelle diagram. The result can be used to infer the ratio of their mean densities very precisely, without reference to theoretical models. In addition, data from the star with the better signal-to-noise ratio can be used to confirm weaker modes and reject sidelobes in data from the second star. Finally, we show that scaled echelle diagrams provide a solution to the problem of ridge identification in F-type stars, such as those observed by the CoRoT space mission.

description: Abstract

Introduction: Tuberculosis (TB) is a communicable disease that is a notable cause of vulnerability, one of the top 10 causes of death worldwide and the foremost cause of death from a single infectious agent. As tuberculosis is a chronic illness, it always interferes life physically, psychosocially, and also economically. Studies have shown that the prevalence of psychiatric disorders, particularly depression, is high among tuberculosis (TB) patients, and may adversely affect treatment compliance. A person suffering from TB can develop depression in due course of time owing to a number of factors. The study's key goals are to determine the prevalence of psychological distress among tuberculosis patients, to comprehend the factors that contribute to psychological distress, and to assess its impact on treatment outcome. Methodology: Cross-sectional study was conducted using quantitative schedule. This research was conducted in the two districts of Gujarat: Vadodara and Chhotaudepur. Random sampling method was used to select 270 samples for this analysis. Telephonic interviews were conducted for data collection. Data on TB patients' socio demographic characteristics, co-morbidities, drug compliance, disease stigma, and patient perceptions of disease seriousness, physical accessibility, and financial status were collected. Results: Numerous factors were identified influencing TB treatment outcomes these included: Depression and anxiety(16%), Substance abuse(9%), Stigma(12%), Social support(21%), Socioeconomic status(18%), and Treatment regimen(14%). Conclusion: By incorporating psychosocial interventions into TB care, healthcare providers can effectively address the complex factors that influence treatment outcomes and contribute to better patient well-being.

description: We present simulated images of Supernova 1993J at 8.4 GHz using Very Long Baseline Interferometry (VLBI) techniques. A spherically symmetric source model is convolved with realistic uv-plane distributions, together with standard imaging procedures, to assess the extent of instrumental effects on the recovered brightness distribution. In order to facilitate direct comparisons between the simulations and published VLBI images of SN1993J, the observed uv-coverage is determined from actual VLBI observations made in the years following its discovery. The underlying source model only exhibits radial variation in its density profile, with no azimuthal dependence and, even though this model is morphologically simple, the simulated VLBI observations qualitatively reproduce many of the azimuthal features of the reported VLBI observations, such as appearance and evolution of complex azimuthal structure and apparent rotation of the shell. We demonstrate that such features are inexorably coupled to the uv-plane sampling. The brightness contrast between the peaks and the surrounding shell material are not as prominent in the simulations (which of course assume no antenna- or baseline-based amplitude or phase errors, meaning no self-calibration procedures will have incorporated any such features in models). It is conclusive that incomplete uv-plane sampling has a drastic effect on the final images for observations of this nature. Difference imaging reveals residual emission up to the 8 sigma level. Extreme care should be taken when using interferometric observations to directly infer the structure of objects such as supernovae.

description: We introduce a model for dynamic networks, where the links or the strengths of the links change over time. We solve the model by mapping dynamic networks to the problem of directed percolation, where the direction corresponds to the evolution of the network in time. We show that the dynamic network undergoes a percolation phase transition at a critical concentration $p_c$, which decreases with the rate $r$ at which the network links are changed. The behavior near criticality is universal and independent of $r$. We find fundamental network laws are changed. (i) For Erdős-Rényi networks we find that the size of the giant component at criticality scales with the network size $N$ for all values of $r$, rather than as $N^{2/3}$. (ii) In the presence of a broad distribution of disorder, the optimal path length between two nodes in a dynamic network scales as $N^{1/2}$, compared to $N^{1/3}$ in a static network.

description: We report the coupling of individual InAs quantum dots (QDs) to an external-mirror microcavity. The external mirror is bonded to a fiber and positioned above a semiconductor sample consisting of a QD-containing GaAs layer on top of a distributed Bragg reflector (DBR). This open cavity can be rapidly tuned with a piezoelectric actuator without negatively affecting the QD linewidth. A mirror radius of curvature of 42 microns and a cavity length of 10 microns enable good mode-matching and thus high collection efficiency directly into the fiber. With an improved finesse this system may enter the strong coupling regime.

description: Transit timing variations (TTVs) can provide useful information for systems observed by transit, as they allow us to put constraints on the masses and eccentricities of the observed planets, or even to constrain the existence of non-transiting companions. However, TTVs can also act as a detection bias that can prevent the detection of small planets in transit surveys that would otherwise be detected by standard algorithms such as the Boxed Least Square algorithm (BLS) if their orbit was not perturbed. This bias is especially present for surveys with a long baseline, such as Kepler, some of the TESS sectors, and the upcoming PLATO mission. Here we introduce a detection method that is robust to large TTVs, and illustrate its use by recovering and confirming a pair of resonant super-Earths with ten-hour TTVs around Kepler-1705. The method is based on a neural network trained to recover the tracks of low-signal-to-noise-ratio(S/N) perturbed planets in river diagrams. We recover the transit parameters of these candidates by fitting the light curve. The individual transit S/N of Kepler-1705b and c are about three times lower than all the previously known planets with TTVs of 3 hours or more, pushing the boundaries in the recovery of these small, dynamically active planets. Recovering this type of object is essential for obtaining a complete picture of the observed planetary systems, and solving for a bias not often taken into account in statistical studies of exoplanet populations. In addition, TTVs are a means of obtaining mass estimates which can be essential for studying the internal structure of planets discovered by transit surveys. Finally, we show that due to the strong orbital perturbations, it is possible that the spin of the outer resonant planet of Kepler-1705 is trapped in a sub- or super-synchronous spin-orbit resonance.

description: This paper investigates the relationship between the USA international travel demand and Turkey’s economic growth over the period 1990-2008. A vector error correction model is employed to test for Granger causality in the presence of co integration between variables. In this study, the impact of the USA international traveler in the Turkish tourism sector is investigated and evaluated by using ADF test, Co-integration approach, and Granger Causality test. The empirical findings indicate a long-run equilibrium relationship and a further uni-directional causality between the two variables.

description: Many worlds interpretations (MWI) of quantum mechanics avoid the measurement problem by considering every term in the quantum superposition as actual. A seemingly opposed solution is proposed by modal interpretations (MI) which state that quantum mechanics does not provide an account of what `actually is the case', but rather deals with what `might be the case', i.e. with possibilities. In this paper we provide an algebraic framework which allows us to analyze in depth the modal aspects of MWI. Within our general formal scheme we also provide a formal comparison between MWI and MI, in particular, we provide a formal understanding of why --even though both interpretations share the same formal structure-- MI fall pray of Kochen-Specker (KS) type contradictions while MWI escape them.

We find that the combination of Brans-Dicke field and holographic dark energy can accommodate $w_D = -1 $ crossing for the equation of state of \textit{noninteracting} holographic dark energy. When an interaction between dark energy and dark matter is taken into account, the transition of $w_D$ to phantom regime can be more easily accounted for than when resort to the Einstein field equations is made.

description: Demand for new methods of beef production is rising due to concern over potential impacts on human health, animal welfare, and the environment. Researchers at Utah State University have developed a method of beef production from cattle finished on tannin-containing legume forages in the Rocky Mountain Region in order to address those concerns. To ensure success of this product, the demand and marketability needed to be assessed. Food values addressed through new production standards and certifications are communicated through labeling by culinary professionals in the kitchen and behind service counters. This research study utilized qualitative methods to understand how culinary leaders construct meaning regarding non-conventional beef. A discursive analysis of labels, menus, and websites revealed that storytelling and branding are more important than third-party certifications. Thematic analysis of interviews with culinary professionals discovered participants are open to new products but environmental concern was tempered by concern for pleasing customers and hindered by planning a menu around consistency and quality. This research found that the success of beef from cattle finished on tannin-containing legume forages is dependent on the benefits being communicated in a way that emphasizes authenticity, tradition, and standards of quality necessary for culinary professionals.

description: Pulsar glitches are rapid spin-up events that occur in the rotation of neutron stars, providing a valuable probe into the physics of the interiors of these objects. Long-term monitoring of a large number of pulsars facilitates the detection of glitches and the robust measurements of their parameters. The Jodrell Bank pulsar timing programme regularly monitors more than 800 radio pulsars and has accrued, in some cases, over 50 years of timing history on individual objects. In this paper we present 106 new glitches in 70 radio pulsars as observed up to the end of 2018. For 70% of these pulsars, the event we report is its only known glitch. For each new glitch we provide measurements of its epoch, amplitude and any detected changes to the spin-down rate of the star. Combining these new glitches with those listed in the Jodrell Bank glitch catalogue we analyse a total sample of 543 glitches in 178 pulsars. We model the distribution of glitch amplitudes and spin-down rate changes using a mixture of two Gaussian components. We corroborate the known dependence of glitch rate and activity on pulsar spin-down rates and characteristic ages, and show that younger pulsars tend to exhibit larger glitches. Pulsars whose spin-down rates between $10^{-14}$ Hz s$^{-1}$ and $10^{-10.5}$ Hz s$^{-1}$ show a mean reversal of 1.8% of their spin-down as a consequence of glitches. Our results are qualitatively consistent with the superfluid vortex unpinning models of pulsar glitches.

description: Large optical surveys provide an unprecedented census of galaxies in the local Universe, forming an invaluable framework into which more detailed studies of objects can be placed. But how useful are optical surveys for understanding the co-evolution of black holes and galaxies, given their limited wavelength coverage, selection criteria, and depth? In this conference paper I present work-in-progress comparing optical and mid-IR diagnostics of three "unusual" low redshift populations (luminous Seyferts, dusty Balmer-strong AGN, ULIRGs) with a set of ordinary star-forming galaxies from the SDSS. I address the questions: How well do the mid-infrared and optical diagnostics of star formation and AGN strength agree? To what extent do optical surveys allow us to include extreme, dusty, morphologically disturbed galaxies in our "complete" census of black hole-galaxy co-evolution?

An Analytical Study of Algorithmic and Expert Summaries of Legal Cases-paper

subject: Natural language processing

description: Automatic summarization of legal case documents is an important and
challenging problem, where algorithms attempt to generate summaries that match
well with expert-generated summaries. This work takes the first step in analyzing
expert-generated summaries and algorithmic summaries of legal case documents.
We try to uncover how law experts write summaries for a legal document, how var-
ious generic as well as domain-specific extractive algorithms generate summaries,
and how the expert summaries vary from the algorithmic summaries. We also an-
alyze which important sentences of a legal case document are missed by most al-
gorithms while generating summaries, in terms of the rhetorical roles of the sen-
tences and the positions of the sentences in the legal document. In this work we try
to determine how to select sentences from a legal document to create a extractive
summary from a legal document in terms of nature of the sentence and position
of the sentence in the legal document. Creating extractive summary from a legal
document is challenging task because we need to determine which sentences are
significant is a document and can be used to create the summary. In our subsequent
works, we can create better algorithms which are closer to the expert generated
summaries.
title: Primary Prevention of Child Abuse and Neglect: Identification of High Risk Adolescents Prior to Parenthood
Creators: name: Bavolek, Stephen John

description: The purpose of the study was to develop a valid and reliable instrument designed to assess the parenting and child rearing attitudes of adolescents, Responses to the instrument would allow for the identification of "high risk" adolescents, i.e., those adolescents whose attitudes towards parenting and child rearing indicated a high potential for child abuse.
A review of the literature identified the following four parenting constructs most commonly associated with abusive parents: Construct A: Inappropriate parental expectations of the child; Construct B: Inability of the parent to be empathically aware of the child's needs; Construct C: Strong parental belief in the value of punishment; Construct D: Role reversal. These constructs served as the basis for the development of the item domain.
The sample used in this study consisted of 2,628 adolescents attending schools located in Utah and Idaho. Employing a Likert format, three Prototypes of the instrument were developed and field tested. Substantial content validity was acquired through the judgments made by a panel of experts in child abuse, test construction, and attitudinal measurement. Construct validity of the instrument was established through the results obtained from factor analysis, interitem correlations, and item-construct correlations.
The data generated from the factor analysis indicated 32 items had the highest positive factor loadings (>= .20) in each of the four identified constructs. The range of item-construct correlations for the 32 items (.53 to .75) indicated adequate to high degrees of relationship between the item scores and total construct scores. The data obtained relative to the internal consistency of the items indicated adequate level s of reliability for each construct (Construct A, .70; Construct B, .75; Construct C, .81; Construct D, .82). The test-retest reliability coefficient of the instrument showed an adequate level of stability over a one week period of time (.76).
Raw scores, converted into factor scores, indicated approximately 3% of the adolescents who responded to the instrument scored -2 and -3 standard deviations away from the mean. The results of the multi-variant analysis of variance indicated that abused adolescents scored significantly lower (p.

description: The goal of genetic-based cancer research is often to identify which genes behave differently in cancerous and healthy tissue. This difference in behavior, referred to as differential expression, may lead researchers to more targeted preventative care and treatment. One way to measure the expression of genes is though a process called RNA-Seq, that takes physical tissue samples and maps gene products and fragments in the sample back to the gene that created it, resulting in a large read-count matrix with genes in the rows and a column for each sample. The read-counts for tumor and normal samples are then compared in a process called differential expression analysis. However, normalization of these read-counts is a necessary pre-processing step, in order to account for differences in the read-count values due to non-expression related variables. It is common in recent RNA-Seq normalization methods to also account for gene-level covariates, namely gene length in base pairs and GC-content, the proportion of bases in the gene that are Guanine and Cytosine.
Here a colorectal cancer RNA-Seq read-count data set comprised of 30,220 genes and 378 samples is examined. Two of the normalization methods that account for gene length and GC-content, CQN and EDASeq, are extended to account for protein coding status as a third gene-level covariate. The binary nature of protein coding status results in unique computation issues. The results of using the normalized read counts from CQN, EDASeq, and four new normalization methods are used for differential expression analysis via the nonparametric Wilcoxon Rank-Sum Test as well as the lme4 pipeline that produces per-gene models based on a negative binomial distribution. The resulting differential expression results are compared for two genes of interest in colorectal cancer, APC and CTNNB1, both of the WNT signaling pathway.
