ABSTRACT Future galaxy surveys will provide accurate measurements of the matter power spectrum across an unprecedented range of scales and redshifts. The analysis of these data will require one to accurately model the imprint of non-linearities of the matter density field. In particular, these induce a non-Gaussian contribution to the data covariance that needs to be properly taken into account to realize unbiased cosmological parameter inference analyses. Here, we study the cosmological dependence of the matter power spectrum covariance using a dedicated suite of N-body simulations, the Dark Energy Universe Simulation–Parallel Universe Runs (DEUS-PUR) Cosmo. These consist of 512 realizations for 10 different cosmologies where we vary the matter density Ωm, the amplitude of density fluctuations σ8, the reduced Hubble parameter h, and a constant dark energy equation of state w by approximately $10{{\ \rm per\ cent}}$. We use these data to evaluate the first and second derivatives of the power spectrum covariance with respect to a fiducial Λ-cold dark matter cosmology. We find that the variations can be as large as $150{{\ \rm per\ cent}}$ depending on the scale, redshift, and model parameter considered. By performing a Fisher matrix analysis we explore the impact of different choices in modelling the cosmological dependence of the covariance. Our results suggest that fixing the covariance to a fiducial cosmology can significantly affect the recovered parameter errors and that modelling the cosmological dependence of the variance while keeping the correlation coefficient fixed can alleviate the impact of this effect.

Abstract INTRODUCTION: Quality improvement projects have begun to standardize surgical work flow as a component to optimize operative room (OR) efficiency. Removing special cause variability resulting from nonsurgical waste is an obvious target; however, surgical resident education must be maintained even in the setting of process improvement. There are no published data describing the impact on operative time of resident-identified risky or uncomfortable procedural steps during posterior instrumented fusion (PIF). Self-identification of risk or discomfort in surgical steps may allow for shorter OR time and reduced cost, without sacrificing resident education. METHODS: PIF procedure steps were defined. An 8 two-part question survey regarding surgeon comfort level and perceived risk assessment at each step was developed, and completed by junior (17) and senior residents (10), and faculty (6) from orthopedic and neurological surgeons. A risk matrix was constructed defining 2 zones, a “danger zone” where responses were both high risk (3–5) and low comfort (1–3) and a “safe zone” where responses were low risk (1–2) and high comfort (4–5). One-tailed χ2 with Yates correction was performed. RESULTS: Risk matrix analysis showed a statistical difference among danger zone respondents between junior resident and faculty groups for exposure, pedicle screw placement, neural decompression, interbody placement, posterolateral fusion, and hemostasis (Table 2). Radar graph identifies percentage of respondents who fall within the danger zone (Figure 1). CONCLUSION: Resident perception of surgical complexity can be evaluated for procedural steps using a risk matrix survey. For PIF, residents assign more risk and are less comfortable performing steps in a training-dependent manner. Identification of particular high-risk steps, which are uncomfortable, should prompt strict faculty oversight to improve patient safety, monitor resident education, and reduce operative time.

The purpose of this work is to present phenology as a valid indicator and methodology for monitoring and assessing the impact of climate change on plant-based tourist activities. Fruit-picking has become a popular rural tourism activity worldwide. However, fruit maturity dates (FMD) have been affected by climate change (CC), which has in turn profoundly affected fruit-picking tourism activities (FPTA). In this paper, phenological data on the FMD for 45 types of plants in 1980–2012, dates for more than 200 fruit-picking festivals, and data on monthly average air temperature in 1980–2013 were used to assess the impact of CC on FPTA by wavelet and correlation analyses. The findings indicated that the study area had been significantly affected by CC. Prevailing temperatures at one or three months prior have a decisive influence on FMD. Among the 11 plants directly related to FPTA, the FMD of four were significantly advanced, while 6-7 were significantly delayed owning to increased temperature. Of the 11 FPTA, only two had realized the impact of CC and had adjusted festival opening dates based on dynamic changes. However, a considerable number of festival activities remained fixed or scheduled on the weekends.

Statistical Operation

A tourism satellite account (TSA) is a synthetic statistical operation closely linked to the central core of a country's national accounts, placing an emphasis on tourism activity. It isolates the various items making up economic tourism activity from the universe of national accounts in order to: specify the impact and describe the direct and indirect effects of tourism on the economy; quantify the overall impact of tourism; analyse the relationships between tourism and the rest of the economy; and make it possible to use major qualitative parameters in analysing tourism activity – place of residence, sex, income, duration of stay, etc. This report outlines the efforts of the World Tourism Organization (WTO) to develop a flexible and sustainable framework for the national and international implementation of TSAs.

This paper describes a framework for evaluating the long-term effect of early project implementation decisions. Early decisions, such as establishing the system architecture and selecting technology of particular maturity, can have lasting impact throughout the project development process and during the project’s operations phase. A systems engineering analysis framework using two different extensions of dependency structure matrix (DSM) analysis was developed to provide a comprehensive system view of the project architecture and the technology choices. An “interface DSM” mapped the dependence of components on one another and identified the impact of component criticality on the project’s operations. A “technology risk DSM” included a component technology risk factor to help identify the patterns of system level risk. This analytical framework can be used to expand the design and management teams’ holistic view of the project, which can be used to enhance project implementation decision-making. The analytical framework described in this paper was applied to two spacecraft projects, which served as case studies. Analytical observations were compared to post-project lessons learned to develop a general understanding of the relationship between the critical elements of each project’s structure and the successful implementation approach for each case.

The Impact

Two previous investigations revealed that grouping (rather than randomizing) questionnaire items measuring similar constructs (in subsections) resulted in impaired discriminant validity (Schrie-sheim and DeNisi, 1980) and that grouping also strengthened the impact of leniency response bias (Schriesheim, 1981). This study reanalyzed the data of the two earlier investigations to determine whether the impairment of the discriminant validity of the grouped questionnaire items might be due to spurious correlations attributable to leniency. The responses of thirty discount store employees to a questionnaire containing grouped items measuring leniency in leader behavior descriptions (Schriesheim, 1980) and four similar constructs from the Leader Behavior Description Questionnaire (Stogdill, 1963) and Four-Factor Theory Questionnaire (Taylor and Bowers, 1972) were examined for convergent and discriminant validity by using a traditional zero-order multitrait-multimethod correlation matrix analysis (Campbell and Fiske, 1959) and by statistically controlling the effect of spurious correlation attributable to leniency (by computing a first-order partial multitrait-multimethod correlation matrix, controlling for leniency as measured by the leniency scale). It was found that controlling for leniency resulted in a slight decrement in convergent validity, but that discriminant validity was substantially improved. Implications for questionnaire validity and further research are discussed.

Dangerous Condition

In July 2018 the movement of the wind from Australia to the Indian Ocean gives the impact on season transition from rainy to dry season. As the result, the wave becomes so much higher than normal condition as it hits the coastal area as well as in the southern part of Yogyakarta Special Province where is directly bordered with the Indian Ocean. Some impacted areas are popular tourism spots like Parangtritis Beach. The wave wrecks several shops along the beach owned by the local people. The majority of damaged objects are semi-permanent buildings constructed by traditional bamboo and timber. Moreover the tourism activity has been warned due to the dangerous condition. The advancement of technology becomes one of popular issues including the increasing of online social media usage. Internet and gadgets such as smartphone are recently the part of people lifestyle. The nowadays people prefer to access anything online through their smartphone including to find the news on the website or social media such as Twitter. One of interested news is about disaster particularly in recognizable places as well as about tidal wave disaster in Parangtritis Beach. This study aims to investigate the advantages of Twitter contents related to the tidal wave in Parangtritis Beach on people response about the disaster and the beach. The analysis applies sentiment analysis theory. Furthermore the data being collected in this research is online from Twitter accounts that has divided into three phases of disaster (before tidal wave, during tidal wave, and after tidal wave).

AbstractCommercial, shipborne tourism along the Antarctic Peninsula grew exponentially between 1989–90 and 2007–08, raising concern about the impact such activity may have on the environment of the region. Previous analyses of Antarctic tourism have focused narrowly on patterns of visitation and potential impacts at terrestrial landing sites. Here, using 19 years of passenger landing statistics and five years of reconstructed ship itineraries, we explore patterns of tourism activities in the Antarctic Peninsula region using a spatially explicit network theory analysis of ship itineraries. We find that passenger landings and marine traffic are highly concentrated at a few specific locations and that growth in tourism activity occurred disproportionally rapidly at these sites relative to growth in visitation of the Peninsula as a whole. We conclude by discussing the pros and cons of spatially concentrated tourism activity and the associated implications for ecosystem management.
