Liberalization assessment: The Greek cruise market

More than thirty years, after the metamorphosis of the cruise industry from an expensive type of vacation for the elite to an aff ordable alternative for the mass market, cruise shipping records high rates of growth. Th e Greek cruise market has been liberalized since 1999, when the Regulation of the European Commission 3577/92 came into force, allowing cruise ships fl ying European flto operate in Greek waters and to use national ports as homeports. Restrictions were in force only for the non EU fl agged cruise ships until 2010, when the Greek Government voted the National Law 3872/2010, which liberalized the market. Until the 1990s Greek companies were pioneers and very active in the international market. However, lately the shrinking of the Greek market is observed. Today, there is only one Greek Cypriot company with just two vessels under the Greek fl ag. At the same time Greece, according to the European Cruise Council (ECC, 2011) data, is among the top three most popular European destinations. Th e paradox is that only a slight percentage of cruise companies select Greek ports for home porting. Th e paper gives an overview of the Greek cruise industry, the cruise cabotage reform, focusing especially on the process and the diff erent opinions expressed by the stakeholders. In addition, the process of deregulation and its potential impacts is evaluated from stakeholders’ viewpoint, particularly the eff ect on retaining and attracting cruise vessels under the Greek flin the context of a national cruise policy.
behavioral and interactional patterns of strip club patrons: tipping techniques and club attendance

In the last three decades a significant amount of research has been done on various aspects of strip clubs. The overwhelming majority of this research has focused on the females who perform at these clubs. Until recently, the patrons who frequent these clubs have been virtually ignored. Using covert participant observation, data were collected on patrons who frequented a small, private, strip club located in a small, rural city in the southeastern United States. Using a synthesis of symbolic interactionism and exchange theory, the club's patrons were analyzed, resulting in a description of the dynamics that constitute a patron as a "regular. " From the data two distinct types of strip club regulars emerged: monetary regulars and frequency regulars. In the former sense, the status of "regular" is dependent on the amount of economic exchange, while in the latter it is dependent on mere frequency of club attendance. In addition, this analysis distinguishes between three distinct methods of tipping and explores the social and structural mechanisms that govern the various tipping techniques. Finally, the research supports prior studies that have addressed the underlying overt and covert motives for frequenting strip clubs.
Stability analysis of hybrid AC/DC power systems for more electric aircraft

This paper presents the stability analysis of a hybrid AC/DC power distribution system, for embedded applications, particularly for more electric aircraft. In the studied system, a balanced AC source supplies the hybrid system, and a DC distribution system feeds multi-converter controlled loads. The load converters are tightly controlled, behaving as constant power loads with low damped LC input filters. An analytical model, taking to account the AC and DC characteristics of the system, is developed to investigate the dynamic behavior of the system. The AC system is modeled in a d-q synchronous reference frame. The stable and unstable operating points are identified using the proposed method, and then, the stability pattern of the system is established. The impacts of the constant power loads and interactions between the source and the load converters on the system's stability are studied. Experimental tests, conducted on a laboratory scale microgrid, validate the analytical system analysis.
The Influence of Perceived Workplace Spirituality on Job Satisfaction, Intention to Leave, and Emotional Exhaustion among Community Mental Health Center Workers in the State of Kansas

THE INFLUENCE OF PERCEIVED WORKPLACE SPIRITUALITY ON JOB SATISFACTION, INTENTION TO LEAVE, AND EMOTIONAL EXHAUSTION AMONG COMMUNITY MENTAL HEALTH CENTER WORKERS IN THE STATE OF KANSAS Social workers are becoming increasingly concerned that work-related factors including low salaries, job insecurity, and hierarchical organizational structures have led to a decline in their job satisfaction, their motivation as employees and an increase in their job turnover intention (Barak, Nissly, & Levin, 2001). There might not be adequate human service management principles to cope with social workers’ emotional burdens, rekindle their motivation, create meaningful experiences at work, and even help them understand and accommodate their clients’ current needs such as spiritual meaning and experiences. The purpose of the study is to present new management principles by applying the concept of Ashmos and Duchon’s workplace spirituality (2000) to the human service field. This study investigated the relationship between five sub-variables (Meaning at Work, Inner Life, Contemplation, Organizational Value, and Individual and Organization) of the Ashmos-Duchon Spiritually Scale (2000) and three workrelated variables (job satisfaction, intention to leave, and emotional exhaustion) and identified key factors that can best predict these three variables among mental health professionals working at the Community Mental Health Centers (CHMC) in the State of Kansas.
Mascot Matters: Race, History, and the University of North Dakota's “Fighting Sioux” Logo

This article critically examines an official document addressing the University of North Dakota's (UND's) “Fighting Sioux” logo. Prior to the civil rights movement of the 1960s, the UND campus was populated mostly by white students, faculty members, and administrators. Such a population created a climate in which the appropriation of Native American images and symbols for fun and sport went largely unquestioned. The debates that have developed since the 1960s around the Fighting Sioux logo reflect the struggles of different groups to define the parameters of acceptable and unacceptable forms of communication.
Body downsizing caused by non-consumptive social stress severely depresses population growth rate

Chronic social stress diverts energy away from growth, reproduction and immunity, and is thus a potential driver of population dynamics. However, the effects of social stress on demographic density dependence remain largely overlooked in ecological theory. Here we combine behavioural experiments, physiology and population modelling to show in a top predator (pike Esox lucius) that social stress alone may be a primary driver of demographic density dependence. Doubling pike density in experimental ponds under controlled prey availability did not significantly change prey intake by pike (i.e. did not significantly change interference or exploitative competition), but induced a neuroendocrine stress response reflecting a size-dependent dominance hierarchy, depressed pike energetic status and lowered pike body growth rate by 23 per cent. Assuming fixed size-dependent survival and fecundity functions parameterized for the Windermere (UK) pike population, stress-induced smaller body size shifts age-specific survival rates and lowers age-specific fecundity, which in Leslie matrices projects into reduced population rate of increase (λ) by 37–56%. Our models also predict that social stress flattens elasticity profiles of λ to age-specific survival and fecundity, thus making population persistence more dependent on old individuals. Our results suggest that accounting for non-consumptive social stress from competitors and predators is necessary to accurately understand, predict and manage food-web dynamics.
Context-specific memory in children with ADHD

Abstract Objectives: Memory for where and when information is learned, or contextual aspects of memory, as opposed to fact or item memory, has been suggested to be more dependent on frontal brain and related executive control systems. Children with neurodevelopmental disorders involving frontal brain systems have been noted to have problems on contextual memory tasks. Children with attention deficit hyperactivity disorder (ADHD) have difficulties with forgetfulness and are known to have deficits in aspects of executive control with associated dysfunction in frontal brain systems; therefore, while their item memory is not typically impaired, they may have difficulty on tasks requiring contextual memory abilities. The goal of this study was to compare children with ADHD to typically developing children, on two different contextual memory tasks (source memory and memory for temporal recency) and to compare this with their respective performance on traditional fact/item memory tasks. Methods: Participants included 36 children with combined type ADHD and 36 typically developing controls ages 6–13 years, matched by age and gender. In addition to a measure of intellectual ability, children completed two different contextual memory tasks; one assessing recall for the source of new information and one assessing recall of the temporal context of information (recency). Incorporated into these tasks were standard measures of item/fact memory recall. Results: Results revealed that children with ADHD performed similarly to control participants on memory recognition tasks, but differed from controls on the contextual memory tasks. Children with ADHD outperformed control participants when recalling the source from which they had learned information, but performed more poorly than control on a task that required them to make a recency/temporal order judgment. Conclusion: The data suggest that while children with ADHD may have somewhat similar capacity to recognise new information, they differ in aspects of their performance on contextual aspects of memory. These differences are not uniform and mirror neuroscience findings supporting dissociable contextual memory systems. Potential theoretical explanations for the dissociations seen are discussed.
Classification of electrooculograph signals: Comparing conventional classifiers using CBFS feature selection algorithm

This work select the features in high dimensional data using CBFS Feature selection algorithm by ElectroOculoGraph (EOG) signals using eye movements of reading and writing task. EOG measures the changes in the electric potential field caused by eye movements. This work has three phases; the first phase identifies and removes noise from the signal. The second phase involves analysis of EOG signals by CBFS Feature Selection method and the third phase classifies EOG signals using various conventional classifiers.
Of Black Boxes, Instruments, and Experts: Testing the Validity of Forensic Science

ABSTRACT This paper argues that judges assessing the scientific validity and the legal admissibility of forensic science techniques ought to privilege testing over explanation. Their evaluation of reliability should be more concerned with whether the technique has been adequately validated by appropriate empirical testing than with whether the expert can offer an adequate description of the methods she uses, or satisfactorily explain her methodology or the theory from which her claims derive. This paper explores these issues within two specific contexts: latent fingerprint examination and the use of breath tests for the detection of alcohol. Especially in the forensic science arena, I suggest courts have often been seduced by superficially plausible explanations and descriptions of a technique or method, and permitted these to serve as a substitute for empirical testing. Thinking through these two examples illustrates both why evaluating the extent of testing should be the most important method by which courts assess reliability, and why, when other forms of explanatory evidence are readily available, we may nonetheless elect to make use of them. This paper suggests that these descriptions and explanations may at times usefully supplement evidence of testing, but should not generally be substituted for it. Finally, this paper embraces a kind of evidentiary pragmatism, in which the quantum of evidence required to establish legal reliability is determined not in the abstract, but in relation to the evidence that is, or ought to be, available as a result of reasonable research and investigation.
MATERNAL EFFECTS INFLUENCE THE SEXUAL BEHAVIOR OF SONS AND DAUGHTERS IN THE ZEBRA FINCH

Abstract Individual differences in sexual behavior have received much attention by evolutionary biologists, but relatively little is known about the proximate causes of this variation. We studied the quantitative genetics of male and female sexual behavior of captive zebra finches and found surprisingly strong maternal effects (differing between individual mothers) on the aggressiveness and song rate of sons and on the daughters' mating preferences for these male traits. We also found that daughters differed in their choosiness during mate-choice experiments depending on whether they originated from eggs produced early or late within the laying sequence of a clutch. Because this effect of laying order occurred independently of hatching order in cross-fostered broods, it must have been caused by consistent within-mother variation in maternal effects transmitted through the egg. Our findings raise the question whether these maternal effects might represent strategic programming of offspring behavior in response to the environment experienced by mothers or whether they are merely nonadaptive byproducts of developmental processes.
Interface and data architecture for query preview in networked information systems

There are numerous problems associated with formulating queries on networked information systems. These include increased data volume and complexity, accompanied by slow network access. This article proposes a new approach to a network query user interfaces that consists of two phases: query preview and query refinement. This new approach is based on the concepts of dynamic queries and query previews, which guides users in rapidly and dynamically eliminating undesired records, reducing the data volume to a manageable size, and refining queries locally before submission over a network. Examples of two applications are given: a Restaurant Finder and a prototype for NASA's Earth Observing Systems Data Information Systems (EOSDIS). Data architecture is discussed, and user feedback is presented.
Deep extragalactic VLBI-optical survey (DEVOS) II. Efficient VLBI detection of SDSS quasars

Context. The Deep Extragalactic VLBI-Optical Survey (DEVOS) aims at constructing a large sample of compact radio sources up to two orders of magnitude fainter than those studied in other Very Long Baseline Interferometry (VLBI) surveys. Optical identification of the objects is ensured by selecting them from the Sloan Digital Sky Survey (SDSS) list. Aims. While continuing to build up the DEVOS data base, we investigated how the VLBI detection rate could be enhanced by refining the initial selection criteria introduced in the first paper of this series. Methods. We observed 26 sources in two adjacent, slightly overlapping 2 ◦ -radius fields with the European VLBI Network (EVN) at 5 GHz frequency on 2 March 2007. The phase-reference calibrator quasars were J1616+3621 and J1623+3909. The objects selected were unresolved both in the Faint Images of the Radio Sky at Twenty-centimeters (FIRST) survey catalogue and the SDSS Data Release 4. Results. We present images of milli-arcsecond (mas) scale radio structures and accurate coordinates of 24 extragalactic sources. Most of them have never been imaged with VLBI. Twenty-two compact radio sources (85% of our initial sample) are considered as VLBI detections of the corresponding optical quasars in SDSS. We found an efficient way to identify quasars as potential VLBI targets with mas-scale compact radio stucture at >1 mJy level, based only on the FIRST and SDSS catalogue data by applying simple selection criteria.
Identity Style and Well-Being: Does Commitment Matter?

A case is made for the role that identity processing styles and identity commitment may play in personal well-being. I argue that research on identity commitment is of interest in its own right and it may also serve to clarify some of the relationships found between identity processing styles and outcome variables. Results from 2 studies are used to illustrate 3 ways in which commitment and processing styles may combine to influence outcome variables: a direct-effects model, a mediated-effects model, and a moderated-effects model. Speculations are advanced regarding different types of identity commitments and the functions they may serve in enhancing well-being and everyday functioning.
Psychological Tests and Drugs*

Automobile accident probability rises with any measurable blood alcohol; yet neither compensatory tracking nor visual search-and-recognition, the major component of the driving task, is impaired by moderate levels of alcohol. The paper presents evidence that the ability to time-share and process information from two or more sources is impaired by alcohol. This ability, essential to the dual component driving task, is suggested as the site of alcohol-induced decrements. Similar analyses of marihuana effects have been performed. In contrast to alcohol effects, performance decrements occurred for perceptual tasks under concentrated attention as well as under divided attention. Marihuana-induced perceptual deficits appear not to be dependent upon division of attention. However, it does not appear that marihuana affects sensory processes directly. A series of tests of simple visual functions failed to reveal any differences between the effects of marihuana and alcohol. It is hypothesized that marihuana may produce brief drop-outs of attention. The nature of the alcohol deficit in performance is related to information processing asnd division of attention, crucial aspects of driving. The nature of the marihuana deficit in performance does not appear as directly linked to the performance requirements of driving. /Author/
Combining static analysis and targeted symbolic execution for scalable bug-finding in application binaries

Symbolic execution is an automated technique for program analysis that has recently become practical due to advances in constraint solvers. Symbolic execution eventually enumerates all feasible program executions, check assertions on all values of varaibles in a program path, and can prioritize executions of interest. However, path explosion, the fact that the number of program executions is typically at least exponential in the size of the program, hinders the adoption of symbolic execution in the real world. In this paper, we present a method for generating test-cases using symbolic execution which reach a given potentially buggy target statement. Such a potentially buggy program statement can be found by static program analysis or from crash-reports given by the users. The test-case generated by our technique serves as a proof of the bug. Generating crashes at the target statement have many applications including re-producing crashes, checking warnings generated by static program analysis tools, or analysis of source code patches in code review process. By constantly steering the symbolic execution along the branches that are most likely to lead to the target program statement and pruning the search space that are unlikely to reach the target, we were able to detect deep bugs in real programs. To tackle the memory requirement due to the exponential growth of program paths, we propose a new scheme to manage program execution paths without exhausting system memory. Experiments on real-life programs demonstrate that our tool WatSym, built on selective symbolic execution engine S2E, can generate crashing inputs in feasible time and order of magnitude better than symbolic approaches (as embodied by S2E) failed.
Evaluating intrusion prevention systems with evasions

Intrusion prevention systems have become a common security measure in the past 20 years. Their promise is the possibility to prevent known attacks against vulnerable, unpatched devices inside enterprise networks. However, evasion techniques that enable the attacker to evade the eye of the intrusion prevention system are a potential problem for this capability. These techniques take advantage of the robustness principle that has guided designers to create systems that will try to recreate protocol content from any input they receive.
Perceived organizational effectiveness, job satisfaction, culture, and communication: Challenging the traditional view

This study challenges the traditional view that organizational culture, relationships, and communication activities precede or produce the outcomes of job satisfaction and perceived organizational effectiveness. Specifically, the study (a) empirically examines job satisfaction and perceived effectiveness for their potential as important explanatory processes for the outcomes of organizational culture, relationships, and information receiving and sending, and (b) empirically compares the traditional model with the competing conceptualization. Results of a canonical correlation analysis utilizing 2245 individuals in 21 organizations in various parts of the world indicate that 54.8% of the variance in perceptions of culture, relationships, information receiving, and information sending can be explained by job satisfaction and perceived organizational effectiveness. Results of a nested model comparison of the two models using latent variable path analysis demonstrated that the competing conceptualization is a significantly better fit to the data than the traditional view.
