Integrated on‐land‐offshore stratigraphy of the Campi Flegrei caldera: New insights into the volcano‐tectonic evolution in the last 15 kyr

Silicic calderas are volcanic systems whose unrest evolution is more unpredictable than other volcano types because they often do not culminate in an eruption. Their complex structure strongly influences the post‐collapse volcano‐tectonic evolution, usually coupling volcanism and ground deformation. Among such volcanoes, the Campi Flegrei caldera (southern Italy) is one of the most studied. Significant long‐ and short‐term ground deformations characterise this restless volcano. Several studies performed on the marine‐continental succession exposed in the central sector of the Campi Flegrei caldera provided a reconstruction of ground deformation during the last 15 kyr. However, considering that over one‐third of the caldera is presently submerged beneath the Pozzuoli Gulf, a comprehensive stratigraphic on‐land‐offshore framework is still lacking. This study aims at reconstructing the offshore succession through analysis of high‐resolution single and multichannel reflection seismic profiles and correlates the resulting seismic stratigraphic framework with the stratigraphy reconstructed on‐land. Results provide new clues on the causative relations between the intra‐caldera marine and volcaniclastic sedimentation and the alternating phases of marine transgressions and regressions originated by the interplay between ground deformation and sea‐level rise. The volcano‐tectonic reconstruction, provided in this work, connects the major caldera floor movements to the large Plinian eruptions of Pomici Principali (12 ka) and Agnano Monte Spina (4.55 ka), with the onset of the first post‐caldera doming at ca. 10.5 ka. We emphasise that ground deformation is usually coupled with volcanic activity, which shows a self‐similar pattern, regardless of its scale. Thus, characterising the long‐term deformation history becomes of particular interest and relevance for hazard assessment and definition of future unrest scenarios.
Envelope following method for the transient analysis of electrical circuits

An envelope following method (EFM) that allows efficient transient simulations of electrical circuits is here presented. Its mathematical and electrical bases are considered and the influence of some general properties, such as stability and truncation error of integration methods employed by EFM, are studied. Furthermore, we present a new state variable prediction algorithm that improves previously reported ones, since it better adapts to fast dynamics of the solution. A set of power switching circuits is employed as a benchmark and numerical results of our algorithm are compared to those of conventional integration and of previous EFM versions. Remarkable results are obtained in the electrothermal simulation of power converters where the efficiency gain rises up to some magnitude orders with respect to conventional integration.
PRELIMINARY DRAFT NOT TO BE QUOTED WITHOUT THE PERMISSION OF AUTHORS, 15/03/18

The demand for letters has been in decline for several years because of electronic (e)-substitution. Some communication that would have taken place previously through letter mail has been replaced by electronic media, much of this process being associated with the expansion and growing use of the Internet. However, there is a dearth of published information on the detail and extent of losses in mail due to e-substitution. Even where data on mail volumes are published it seems likely that the trends observed cannot be explained adequately by the negative effects of e-substitution alone for the impacts from other variables that historically have influenced volumes, such as economic activity (GDP), prices and quality of service, appear to remain in place (Jarosik et al., 2013).
Genomic analysis of a reef‐building coral, Acropora digitifera, reveals complex population structure and a migration network in the Nansei Islands, Japan

Understanding the structure and connectivity of coral populations is fundamental for developing marine conservation policies, especially in patchy environments such as archipelagos. The Nansei Islands, extending more than 1000 km in southwestern Japan, are characterized by high levels of biodiversity and endemism, supported by coral reefs, which make this region ideal for assessing genetic attributes of coral populations. In this study, we conducted population genomic analyses based on genome‐wide, single‐nucleotide polymorphisms (SNPs) of Acropora digitifera, a common species in the Nansei Islands. By merging newly obtained genome resequencing data with previously published data, we identified more than 4 million genome‐wide SNPs in 303 colonies collected at 22 locations, with sequencing coverage ranging from 3.91× to 27.41×. While population structure analyses revealed genetic similarities between the southernmost and northernmost locations, separated by >1000 km, several subpopulations in intermediate locations suggested limited genetic admixture, indicating conflicting migration tendencies in the Nansei Islands. Although migration networks revealed a general tendency of northward migration along the Kuroshio Current, a substantial amount of southward migration was also detected, indicating important contributions of minor ocean currents to coral larval dispersal. Moreover, heterogeneity in the transition of effective population sizes among locations suggests different histories for individual subpopulations. The unexpected complexity of both past and present population dynamics in the Nansei Islands implies that heterogeneity of ocean currents and local environments, past and present, have influenced the population structure of this species, and similar unexpected population complexities may be expected for other marine species with similar reproductive modes.
Bird diversity on shelf islands does not benefit from recent land‐bridge connections

Research in island biogeography has long focused mainly on present‐day island configurations. Recently, there has been an increasing focus on islands’ past histories of land connection, shape and size. Moreover, continental islands (=shelf islands) have received less attention than oceanic islands, and species inventories from extremely small islands are lacking in many datasets. We examine the effects of sea‐level rise since the Last Glacial Maximum (LGM) on bird species diversity and composition of tropical shelf islands in Southeast Asia.
Anti-immigrant Attitudes in the European Union: What Role for Values?

This paper aims to analyse the connection between values individuals hold and perception whether immigration is bad or good for economy in the European Union. It applies the multilevel modelling approach on the European Social Survey rounds 1–7 and a set of the OECD economic measures. The method allows for an examination of personal (values, socioecomic and demographic) and contextual (GDP, inequality and unemployment rates) drivers of anti-immigrant tendencies. The results show that individual values are connected to how people perceive immigrants in the EU.
Switching and second harmonic generation using counterpropagating quasi-phase-matching in a mirrorless configuration

Numerical solutions to the set of coupled nonlinear wave equations for a novel mirrorless counterpropagating quasi-phase-matched (c-QPM) device are presented. Mirrorless c-QPM is investigated in stand-alone and in two interferometric configurations for all-optical switching (AOS) applications. The switching intensity is found to be very low using existing materials (e.g., 500 mW in a 1-cm-long KTP waveguide with a 10 /spl mu/m/sup 2/ effective area). Additionally, parameter sets are found that minimize pulse breakup and improve the possibility of a practical implementation. Although second harmonic generation (SHG) is also investigated in the stand-alone device, the conversion efficiency is shown to be eight times less efficient than the mirrored configuration.
The role of usability, aesthetics, usefulness and primary task support in predicting the perceived credibility of academic social networking sites

ABSTRACT With technology being ubiquitous in our daily lives, it is crucial to understand the factors that influence their perceived credibility. In the current research, we focus on the design of Academic Social Networking Sites (ASNSs). In order to facilitate continuous adoption and use of ASNSs, it is important to understand the factors that determine their Perceived Credibility. Using the Persuasive System Design (PSD) framework as a foundation, the study investigated which of these four key constructs (i.e. Perceived Aesthetics, Perceived Usability, Perceived Usefulness and Perceived Primary Task Support) are the most relevant determinants of the Perceived Credibility of ASNSs. In an online survey, the current research assessed this research model. The results of Partial Least Square analyses confirmed that Perceived Aesthetics, Perceived Usefulness and Perceived Primary Task Support are determinants of Perceived Credibility but provided no evidence for Perceived Usability as a determinant. Moreover, the results showed that Perceived Primary Task Support was the most relevant determinant of Perceived Credibility. Implications of these findings are discussed.
Reliability of special protection systems

Special protection systems (SPS) have been widely used to increase the transfer capability of the network by assisting system operators in administering fast corrective actions. Compared with constructing new transmission facilities, SPS can be placed in service relatively quickly and inexpensively. However, increased reliance on SPS results in additional risks to system security. The purpose of this paper is to elucidate the importance of developing a systematic and comprehensive reliability framework for SPS. We review types of SPS and provide several examples of actual SPS failures. The need for SPS reliability assessment is discussed. Several reliability assessment methods are described, and efforts to deal with a similar problem in the process control industry are summarized. We also provide several recommendations.
Designettes: New Approaches to Multidisciplinary Engineering Design Education

Teaching of engineering design and other fundamental engineering topics is often isolated to dedicated courses, missing an opportunity to foster a culture of engineering design and multidisciplinary problem solving throughout the curriculum. Designettes, defined as brief, vignette-like design challenges, provide the opportunity to integrate design learning experiences in class, across courses, across terms, and across disciplines. When fundamental engineering courses join together in a designette, a multidisciplinary learning activity occurs, demonstrating how subjects are integrated and applied to open-ended problems and grand challenges. The development of designettes helps foster a culture of design, and enables the introduction of multidisciplinary design challenges across all core courses in each semester. These challenges combine problem clarification, concept generation and prototyping with subject content from curricula such as biology, thermodynamics, differential equations, and software with controls. This paper provides examples and investigates the use of single and multidisciplinary designettes over a two-year history of designettes at SUTD. From pre- and post-surveys of junior college students, designettes were found to increase students’ awareness of applications and the learning of content. From 321 third-semester students across six cohorts, designettes were found to increase students’ self-perceptions of their ability to solve multidisciplinary problems.
Prevalence of depression and associated factors among undergraduate medical students

Background: Depression has become one of the commonest mental ailments in current era. Its impact is far more in medical personnel than general population. Most of the medical students leave their houses for the first time and enter into the new environment of knowledge and responsibility. Though various studies have reported high prevalence of depression among undergraduate students, it was desirable to know its status in south Rajasthan. Methodology: A cross sectional study was conducted on 302 undergraduate medical students to know prevalence and risk factors for depression. Along with the pre-designed questionnaire, Beck Depression Inventory (BDI) Scale was used as study tools. Cut off value of 17 and above was considered to define the depression on BDI scale. Results: Prevalence of depression was 10% among undergraduate medical students. Statistically, female gender and students studying in fifth semester were significant risk factors. Residence, socio-economic class and family history of depression were not significant associated factors. Conclusion: Prevalence of depression is higher among medical undergraduates as compared to general population with female gender and fifth semester students being important risk factors.
Computation of bridge seismic fragility by large‐scale simulation for probabilistic resilience analysis

Seismic resilience of structures and infrastructure systems is a fast developing concept in the field of disaster management, promoting communities that are resistant and quickly recoverable in case of an extreme event. In this contest, probabilistic seismic demand and fragility analyses are two key elements of the seismic resilience assessment in the majority of the proposed methodologies. Several techniques are available to calculate fragility curves for different types of structures. In particular, to assess the seismic performance of the regional transportation infrastructure, methods for the fragility curve estimation for entire classes of bridges are required. These methods usually rely on a set of assumptions, partially because of the limited information. Other assumptions were introduced at the time when computational resources were inadequate for a purely numerical approach and closed‐form solutions were a convenient alternative. For instance, some of these popular assumptions are aimed at simplifying the model of the engineering demand. In this paper, a simulation‐based methodology is proposed, to take advantage of the computational resources widely available today and avoid such assumptions on the demand. The resulting increase in accuracy is estimated on a typical class of bridges (multi‐span simply supported). Most importantly, the quantitative impact of the assumptions is assessed in the context of a life‐cycle loss estimation analysis and resilience analysis. The results show that some assumptions preserve an acceptable level of accuracy, but others introduce a considerable error in the fragility curves and, in turn, in the expected resilience and life‐cycle losses of the structure.

THE HOTEL SERVICE CHALLANGES IN SRI LANKA

Sri Lanka is one of the world famous holiday destinations for its remarkable natural tourism resources and authentic food culture. Despite the fact that tourists enjoy a significant tourism experience in Sri Lanka, the hotel industry has faced issues with the limited management concern on human resources (HR) and employees’ low motivation to provide professional services. Considering the lack of academic research focused on the improvement of service in Sri Lankan hotel industry, this study aims to identify the current key challenges from the three perspectives of hotel organizations, employees and guests. Secondary data are qualitatively collected and analyzed from the travel review websites, blogs and several other sources. This study also, conducts interviews with Sri Lankan Tourism Board, Hotel management training institute executive officers and tourists around the Island. In addition, reviewed the findings from the previous literatures and empirical researches on the service improvement and the HR practices in the context of hospitality industry. Recommendations have also been put forward on the following three aspects: (1) hotel management and relevant HR-practices, (2) hotel career aspects of employees, and (3) guests’ perception. Finally, this study emphasizes that deeper consideration on the three parts can be a foundation to strengthen the human resources of the Sri Lankan hotel industry.
Variational formulation of Poisson's equation in semiconductor at quasi-equilibrium and its applications

Variational formulation of Poisson's equation with Boltzmann carrier statistics at quasi-equilibrium is used to find analytical solutions of the potential distribution in multidimensional semiconductor devices with reasonably good accuracy. To demonstrate this approach, short-channel effects in the threshold voltage of fully-depleted SOI MOSFETs are analyzed. The usefulness of our idea is extended further to determine the quasi-Fermi potential of the floating gate of an EEPROM device, which has been determined to be very difficult to find by conventional methods.
Coordinating the technology transfer and transition of information technology: a phenomenological perspective

Legislation mandates that America's national laboratories share their expertise in developing and commercializing technological innovations. Similarities and differences between the new-product development process (NPDP), as practiced by corporations, versus processes involved in technology movement, as practiced by the national labs, are discussed. The major stages within each and the activities key to the success of each stage are identified. The emphasis is on the need to coordinate the transition and transfer processes within the laboratory organizations affiliated with the Department of Defense (DoD). Data were collected from one of the "best of the best" DoD labs. Personal interviews and mail questionnaires were used to gather the perceptions of employees involved with developing and refining 22 innovative information technologies. The phenomenological approach to data collection and analysis was used. The findings suggest that technology movement embodies seven stages that parallel NPDP. When viewed over all seven, technology transfer is perceived to be more reflective of "technology push," while transition is more like "market pull. " The NPDP embraces elements of both transfer and transition. The implications of coordinating both are discussed, as well as ways to enhance communication among all parties involved.

ertrand-Edgeworth competition with substantial horizontal product di erentiation

Since Kreps and Scheinkman's seminal article (1983) a large number of papers have analyzed capacity constraints' potential to relax price competition. However, the majority of the ensuing literature has assumed that products are either perfect or very close substitutes. Therefore very little is known about the interaction between capacity constraints and local monopoly power. The aim of the present paper is to shed light on this question using a standard Hotelling setup. The high level of product di erentiation results in a variety of equilibrium rm behavior and it generates at least one pure-strategy equilibrium for any capacity level.
