    I am honoured to take on the leadership of Plasma Sources Science and Technology (PSST) as the successor to Professor Mark J Kushner, with whom I have had the pleasure to work on the journal for many years. Under Mark's insightful and energetic leadership over the last six years, PSST has cemented its position as the journal of choice within its subject area and is now one of the most successful journals in the field. In this first issue of 2014, I would like to reflect on some of the events and achievements of 2013. At the start of the year the PSST Editorial Board, recognizing the vital importance of atomic, molecular and optical (AMO) data to low-temperature plasma physics, agreed that PSST would accept papers reporting such new data, generated through both experiment and theory. Jonathan Tennyson joined the Editorial Board to represent this area. In March Anne Bourdon joined the Associate Editor team and has since then played a key part in the journal's review process alongside our other Editors. During the autumn, PSST moved to a new editorial management system. In December Deborah O'Connell was awarded the 2013 Hershkowitz Early Career Award and Review and joins the Editorial Board as of 2014. I would also like to thank Miles Turner for his work in leading the drafting of a guide on the details necessary in the reporting of the results of computer simulations; the main conclusions of this report have been incorporated into the journal policy. Overall 2013 has been another successful year for PSST; paper submissions were up by 8% on the previous year and there was the highest ever number of downloads of PSST papers in one year. Another noteworthy feature of 2013 was the continuing improvement in publication times while maintaining our high standards for acceptance and providing expert feedback coupled with encouragement particularly to younger researchers and groups. Largely as a result of the hard work of our referees and Associate Editors, the average time

    2006-09-01

    Synthetic chemists have provided a wide array of supramolecular assemblies able to encapsulate guest molecules. The scope of this tutorial review focuses on supramolecular host molecules capable of reversibly encapsulating polyatomic guests. Much work has been done to determine the mechanism of guest encapsulation and guest release. This review covers common methods of monitoring and characterizing guest exchange such as NMR, UV-VIS, mass spectroscopy, electrochemistry, and calorimetry and also presents representative examples of guest exchange mechanisms. The guest exchange mechanisms of hemicarcerands, cucurbiturils, hydrogen-bonded assemblies, and metal-ligand assemblies are discussed. Special attention is given to systems which exhibit constrictive binding, a motif common in supramolecular guest exchange systems.

    Full Text Available Abstract The Institut National de la Recherche Agronomique (INRA was honoured to welcome scientists from all over the world who attended the International Workshop on major Genes and QTL in Sheep and Goats. Approximately 100 participants from 16 countries were registered, contributing 52 oral or poster presentations. A first session was dedicated to the tools available for identifying and localising major genes or QTL in these two species. Molecular techniques, marker panels, radiation hybrids, genome physical maps, and BAC libraries were presented along with genetic, comparative and cytogenetic maps. A second and largest session concerned different traits for which major genes or QTL have been found, i.e., ovulation and other reproduction traits, milk and meat characters, and resistance to disease and wool production. For each group, a guest's paper focused on one sub-trait gave the state of the art: the history, identification and localisation of sources of monogenic and oligogenic variability, genetic determinism (dominance, imprinting, ..., effects on the phenotype, physiological mechanisms implied, use in populations, etc. The third session was devoted to the strategies for the use of major genes and QTL in populations, while the last session covered future prospects. A CD (available on request to bodin@toulouse.inra.fr of the full proceedings was available, and participants invited to give a main paper also had the opportunity to submit it for publication in this special issue of GSE. Nine articles were jointly selected by the Editorial Board of the journal and by the Guest Editor.

    Full Text Available  This issue of Seminar.net contains three articles that were written in connection with a Norwegian e-learning conference titled “Networked collaboration, sharing and response”. The conference was held in Mars 2008 in Trondheim, and the presentations from the conference is available (in norwegian language at http://www.nvu.no. Networked collaboration was chosen as a theme because collaboration is important to achieve learning, according to the social-constructivistic pedagogy that has a strong standing in Norway, but how should this occur on the net? Sharing of content, as in digital learning resources, is a phenomenon with increasing popularity as described in the OECD-report “Giving Knowledge for Free”. But to achieve reuse of content, not only publishing it, it is important with a networked community where the plethora of information can be sorted with relevance to specific topics. Response is about guiding, coaching and tutoring. In what ways may resources and tools be used to move in the direction of solving Bloom’s two sigma problem/challenge? The first article, by Morten Flate Paulsen, shows how cooperative learning can be implemented successfully so that students have optimal individual freedom within online learning communities. The second article, by Carl F. Dons, shows how student teachers can be prepared to deal with pupils who have a wide range of experiences of the digital world. The third and last article, by Kristin Dale, is sharing experiences with multiple choice-tests to give midterm responses to students. In addition, this issue has a commentary article by Rune Krumsvik discussing the need to develop new practices for teachers and students on the background of the digital developments. The conference and articles covers three big themes. It may be difficult to find more important issues, apart from finding money and time to support its development. Olav Skundberg, guest editorAssociate professor

At present, in many areas across the world, wind and solar energy are providing substantial proportions of the total electrical demand......, rising to over 50% in certain regions. However, many renewable energy sources, e.g. modern variable speed wind turbines and photovoltaic systems, are significantly different from conventional thermal and hydropower generating technologies, since they synchronize to the electricity grid via power...... electronics converters, and so are not directly responsive to system frequency transients.

The previous Editor-in-Chief, Laurens Molenkamp, University of Würzburg, Germany, has worked tirelessly for the last ten years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements In 2012 several new members will join the Editorial Board: Professor Deli Wang (University of California, San Diego) with considerable expertise in semiconductor nanowires, Professor Saskia Fischer (Humboldt University, Berlin, Germany) with a background in semiconductor quantum devices, and Professor Erwin Kessels (Eindhoven University of Technology, Netherlands) with extensive experience in plasma processing of thin films and gate oxides. In particular, I want to express my gratitude to Professor Israel Bar-Joseph (Weizmann Institute of Science, Israel) and Professor Maria Tamargo (The City College of New York, USA), who will leave next year and who have vigorously served the Editorial Board for years. The journal has recently introduced a fast-track option for manuscripts. This option is a high-quality, high-profile outlet for new and important research across all areas of semiconductor research. Authors can expect to receive referee reports in less than 20 days from submission. Once accepted, you can expect the articles to be online within two or three weeks from acceptance and to be published in print in less than a month.

    Full Text Available It has been my pleasure to be the acting editor of IRRODL while Dr. Terry Anderson has been on sabbatical leave. While the value and need for academic sabbaticals has been passionately debated for decades (and will likely continue to be debated for decades to come, within the academy most, if not all, academics understand both the value and need for a career pause.An academic sabbatical is a prolonged leave, typically for one year after six years of continuous employment. Harvard University was the first to grant academics a sabbatical in 1880. The primary purpose was, and still is, to provide an opportunity for academics to fulfill a career goal (i.e., write a book, travel for research or an opportunity for collegial inter-visitations. The word ‘sabbatical’ has biblical origins connected to the practice of leaving land unplanted as a means of rejuvenation. The word originates from the Mosaic law of ancient Judea, during which farmers left land fallow for a year after six consecutive harvests. The spirit of rejuvenation and harvesting has remained unchanged within the academy. Similar to ‘leaving the land unplanted,’ academics ‘leave the daily demands of university life’ (e.g., teaching and service commitments for an opportunity to regenerate new ideas and pursue professional growth.

    2015-01-01

    Full Text Available The continuous growth of competition in the hospitality sector has created the need to retain guests and prevent them from switching company due to better offer or saturation. Loyal customers are a valuable asset for catering companies, not only because of the awareness of the effects of customer loyalty. They tend to spread word-of-mouth advertising, more tolerant to price changes, as well as they casually create a linkage to their friends, relatives, colleagues, and other probable consumers and thus enable businesses to uphold a guest's base. By recognizing loyalty guests' importance, the global hospitality industry created monetary and non-monetary rewards for loyal visitors, delayed gratification (points collection and immediate rewards, as well as numerous other reward systems that try to keep them. To win customer loyalty, together with all benefits arising from it, caterers need to become familiar with factors, which determine guests' loyalty. The paper will show the results of research regarding the impact of the service quality and guests' satisfaction to their loyalty. Many authors have confirmed that employees' satisfaction affected customers' satisfaction, so this paper will give an answer does it influence on customers' loyalty as well.

    On July 14, 2015, after 9.5 years of cruise, NASA's New Horizons spacecraft flew past the Pluto system to gather first images humankind had ever seen on Pluto and its five moons. While much has been discovered about the Pluto system since New Horizons launch in 2006, the system has never been imaged at high resolution and anticipation of the "First Light" of the Pluto system had been anticipated by planetary enthusiasts for decades. The Johns Hopkins Applied Physics Laboratory (APL), which built and operates New Horizons, was the focal point for gathering three distinct groups: science and engineering team members; media and public affairs representatives; and invited public, including VIP's. Guest operations activities were focused on providing information primarily to the invited public and VIP's. High level objectives for the Guest Operations team was set to entertain and inform the general public, offer media reaction shots, and to deconflict activities for the guests from media activities wherever possible. Over 2000 people arrived at APL in the days surrounding closest approach for guest, science or media operations tracks. Reaction and coverage of the Guest Operations events was universally positive and global in impact: iconic pictures of the auditorium waving flags during the moment of closest approach were published in media outlets on every continent. Media relations activities ensured coverage in all key media publications targeted for release, such as the New York Times, Science, Le Monde, and Nature. Social and traditional media coverage of the events spanned the globe. Guest operations activities are designed to ensure that a guest has a memorable experience and leaves with a lifelong memory of the mission and their partnership in the activity. Results, lessons learned, and other data from the New Horizons guest operations activity will be presented and analyzed.

    Full Text Available This research aimed to describe guests’ perceived value by using a multidimensional approach. From previous research, guests’ perceived value consisted of some functional value, emotional value, and social value. Based on guest experience, and functional value consisted of physical evidence, guest room, food and beverage, hotel staff, and price. This research was conducted in four-star hotels in Jakarta. The respondents were the guests who had stayed in four-star hotels. The number of the respondent was 405. The data were obtained by using self-administered questionnaires. This research shows that guests have not perceived superior value. Some of the values and the necessary efforts need to be improved.

  8. Mechanism of host-guest complexation by cucurbituril.

    Science.gov (United States)

    Márquez, César; Hudgins, Robert R; Nau, Werner M

    2004-05-12

    The factors affecting host-guest complexation between the molecular container compound cucurbit[6]uril (CB6) and various guests in aqueous solution are studied, and a detailed complexation mechanism in the presence of cations is derived. The formation of the supramolecular complex is studied in detail for cyclohexylmethylammonium ion as guest. The kinetics and thermodynamics of complexation is monitored by NMR as a function of temperature, salt concentration, and cation size. The binding constants and the ingression rate constants decrease with increasing salt concentration and cation-binding constant, in agreement with a competitive binding of the ammonium site of the guest and the metal cation with the ureido carbonyl portals of CB6. Studies as a function of guest size indicate that the effective container volume of the CB6 cavity is approximately 105 A(3). It is suggested that larger guests are excluded for two reasons: a high activation barrier for ingression imposed by the tight CB6 portals and a destabilization of the complex due to steric repulsion inside. For example, in the case of the nearly spherical azoalkane homologues 2,3-diazabicyclo[2.2.1]hept-2-ene (DBH, volume ca. 96 A(3)) and 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO, volume ca. 110 A(3)), the former forms the CB6 complex promptly with a sizable binding constant (1300 M(-1)), while the latter does not form a complex even after several months at optimized complexation conditions. Molecular mechanics calculations are performed for several CB6/guest complexes. A qualitative agreement is found between experimental and calculated activation energies for ingression as a function of both guest size and state of protonation. The potential role of constrictive binding by CB6 is discussed.

  15. A Tunable Cyclic Container: Guest-Induced Conformational Switching, Efficient Guest Exchange, and Selective Isolation of C70 from a Fullerene Mixture.

    Science.gov (United States)

    Mondal, Pritam; Rath, Sankar Prasad

    2017-07-18

    An adaptable cyclic porphyrin dimer with highly flexible linkers has been used as an artificial molecular container that can efficiently encapsulate various aromatic guests (TCNQ/C 60 /C 70 ) through strong π-π interactions by adjusting its cavity size and conformation. The planar aromatic guest (TCNQ) can be easily and selectively exchanged with larger aromatic guests (C 60 /C 70 ). During the guest-exchange process, the two porphyrin rings switch their relative orientation according to the size and shape of the guests. This behavior of the cyclic container has been thoroughly investigated by using UV/Vis spectroscopy, NMR spectroscopy, and X-ray crystal structure determination of the host-guest assemblies. The electrochemical and photophysical studies demonstrated the occurrence of photoinduced electron transfer from bisporphyrin to TCNQ/C 60 /C 70 in the respective host-guest assemblies. The cyclic host can form complexes with C 60 and C 70 with association constants of (2.8±0.2)×10 5 and (1.9±0.3)×10 8  m -1 , respectively; the latter value represents the highest binding affinity for C 70 reported so far for zinc(II) bisporphyrinic receptors. This high selectivity for the binding of C 70 versus C 60 allows the easy extraction and efficient isolation of C 70 from a C 60 /C 70 fullerene mixture. Experimental evidence was substantiated by DFT calculations. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The significance of guest workers is examined for six Western European countries. It is found that "the dynamics of the migratory process led to family reunification and settlement, against the original intentions of the workers, employers and states concerned. The recruitment of guest-workers stopped after 1974, but many migrants stayed on, becoming permanent ethnic minorities, in a situation of economic and social crisis. It is argued that guest-worker systems inevitably lead to permanent migration in the long run, and that it is better to plan for orderly settlement through appropriate policies." excerpt

  5. Supramolecular polymeric materials via cyclodextrin-guest interactions.

    CONSPECTUS: Cyclodextrins (CDs) have many attractive functions, including molecular recognition, hydrolysis, catalysis, and polymerization. One of the most important uses of CDs is for the molecular recognition of hydrophobic organic guest molecules in aqueous solutions. CDs are desirable host molecules because they are environmentally benign and offer diverse functions. This Account demonstrates some of the great advances in the development of supramolecular materials through host-guest interactions within the last 10 years. In 1990, we developed topological supramolecular complexes with CDs, polyrotaxane, and CD tubes, and these preparation methods take advantage of self-organization between the CDs and the polymers. The combination of polyrotaxane with αCD forms a hydrogel through the interaction of αCDs with the OH groups on poly(ethylene glycol). We categorized these polyrotaxane chemistries within main chain type complexes. At the same time, we studied the interactions of side chain type supramolecular complexes with CDs. In these systems the guest molecules modified the polymers and selectively formed inclusion complexes with CDs. The systems that used low molecular weight compounds did not show such selectivity with CDs. The multivalency available within the complex cooperatively enhances the selective binding of CD with guest molecules via the polymer side chains, a phenomenon that is analogous to binding patterns observed in antigen-antibody complexes. To incorporate the molecular recognition properties of CDs within the polymer side chains, we first prepared stimuli-responsive sol-gel switching materials through host-guest interactions. We chose azobenzene derivatives for their response to light and ferrocene derivatives for their response to redox conditions. The supramolecular materials were both redox-responsive and self-healing, and these properties resulted from host-guest interactions. These sol-gels with built in switches gave us insight for

    2004-01-01

    Full Text Available Editorial Notes provide a view "behind the scenes" of FQS Reviews, reporting and describing the editorial process. The first topic in this Editorial Note focuses on changes in the way reviewers are found. As FQS Reviews began we preferred finding reviewers by posting on different listservs to inform others about review copies of books and other media. In the next phase of FQS Reviews—aside from postings—we attempted to establish a core of authors who would exclusively write reviews. The second topic describes an analyses of 131 archived files (first drafts of reviews published in FQS and the analyses of the e-mail contacts between the reviewers and the editorial team which accompany the peer review process. One result of our analyses is that the quality of a review is independent from way the reviewer was recruited (postings on listservs or established core reviewer; no significant differences can be seen between the two groups (reviewers found via listservs or established reviewers. More, important, however, is the intensive "communication work" between editors and reviewers—a necessary communication to guarantee standardization and maintenance of quality. This is critical as our focus is on the review as a "unique contribution" within the research community. To give an insight into the intensive communication work an anonymous case study of a "failed" review is included. URN: urn:nbn:de:0114-fqs040115

    A proof-of-concept related to the redox-control of the binding/releasing process in a host-guest system is achieved by designing a neutral and robust Pt-based redox-active metallacage involving two extended-tetrathiafulvalene (exTTF) ligands. When neutral, the cage is able to bind a planar polyaromatic guest (coronene). Remarkably, the chemical or electrochemical oxidation of the host-guest complex leads to the reversible expulsion of the guest outside the cavity, which is assigned to a drastic change of the host-guest interaction mode, illustrating the key role of counteranions along the exchange process. The reversible process is supported by various experimental data ( 1 H NMR spectroscopy, ESI-FTICR, and spectroelectrochemistry) as well as by in-depth theoretical calculations performed at the density functional theory (DFT) level. © 2017 Wiley-VCH Verlag GmbH & Co.

    Full Text Available Total quality management (TQM has become a modern system of constant improvement of the quality of all company activities. The purpose of this study is to measure the expectations and satisfaction of the guests concerning the attribute quality of the hotel product. Furthermore obtained results were compared in such a way as to analyse particularly the reviews of hotels which have implemented TQM and have the ISO 9001 certificates with reviews from hotels which have not implemented TQM and do not have the ISO 9001 certificates. The conducted analysis included 55 hotels in Serbia belonging to the 4- and 5-star categories, i.e. 1308 guests who have stayed in them. The results show that between the observed groups of guests there are fewer differences in expectations than in perception, and that generally speaking guests who have stayed in the hotels that have implemented TQM are more satisfied. The biggest difference concerning the guest satisfaction with the quality of service in the observed hotels is noticeable in relation to the employees and the value-for-money.

    Full Text Available This article discusses the concept of a customer as an asset of business in the accommodation industry. The purpose of this article is to examine the value of guests as a firm asset and to propose a model for managing guests as an asset in the context of accommodation services. A guest is considered an asset due to its role in providing revenue to the accommodation firm. Because of this role, the accommodation guest needs to be managed appropriately. This article argues that guest service evaluation (i.e. service quality, perceived value, and guest satisfaction and service loyalty are important factors in the development of guest lifetime value. The proposed model of managing guests as an asset consists of marketing instruments, service evaluation, guest loyalty, and financial outcomes provides a comprehensive guide on how accommodation firms can manage the lifetime value of their guests. Finally, as there are limited studies examining this issue, future research should test the proposed model.

    Recent X-ray crystal structural data for two novel 1:2 host-guest complexes of 18-crown-6 with neutral organic molecules, thiaamide hydrazide of 2-aminobenzoic acid and thiaamide hydrazide of 4-amino-1,2,5-thiadiazole-3-carbonic acid are reported. The supramolecular structures of these two and five relative complexes are discussed from the point of view of participation of donor groups in coordination with the crown ether, and donor and acceptor groups in the self-assembly of the guest molecules. Guest molecules have incorporated amine and hydrazine moieties as proton donors and carbonyl oxygen and sulfur (in thiadiazole and in thiaamine moieties) as proton acceptors. The guest-guest interactions appeared to be crucial in the final architecture.

  14. Guest Controlled Nonmonotonic Deep Cavity Cavitand Assembly State Switching.

    2017-11-30

    Octa-acid (OA) and tetra-endo-methyl octa-acid (TEMOA) are water-soluble, deep-cavity cavitands with nanometer-sized nonpolar pockets that readily bind complementary guests, such as n-alkanes. Experimentally, OA exhibits a progression of 1:1 to 2:2 to 2:1 host/guest complexes (X:Y where X is the number of hosts and Y is the number of guests) with increasing alkane chain length from methane to tetradecane. Differing from OA only by the addition of four methyl groups ringing the portal of the pocket, TEMOA exhibits a nonmonotonic progression of assembly states from 1:1 to 2:2 to 1:1 to 2:1 with increasing guest length. Here we present a systematic molecular simulation study to parse the molecular and thermodynamic determinants that distinguish the succession of assembly stoichiometries observed for these similar hosts. Potentials of mean force between hosts and guests, determined via umbrella sampling, are used to characterize association free energies. These free energies are subsequently used in a reaction network model to predict the equilibrium distributions of assemblies. Our models accurately reproduce the experimentally observed trends, showing that TEMOA's endo-methyl units constrict the opening of the binding pocket, limiting the conformations available to bound guests and disrupting the balance between monomeric complexes and dimeric capsules. The success of our simulations demonstrate their utility at interpreting the impact of even simple chemical modifications on supramolecular assembly and highlight their potential to aid bottom-up design.

    There has been considerable debate about the intrinsic PPII propensity of amino acid residues in denatured polypeptides. Experimentally, this scale is based on the behavior of guest amino acid residues placed in the middle of proline-based hosts. We have used classical molecular dynamics simulations combined with replica-exchange methods to carry out a comprehensive analysis of the conformational equilibria of proline-based host oligopeptides with multiple guest amino acids including alanine, glutamine, valine, and asparagine. The tracked structural characteristics include the secondary structural motifs based on the Ramachandran angles and the cis/trans isomerization of the prolyl bonds. In agreement with our recent study of single amino acid guests, we did not observe an intrinsic PPII propensity in any of the guest amino acids in a multiple-guest setting. Instead, the experimental results can be explained in terms of (i) the steric restrictions imposed on the C-terminal guest amino acid that is immediately followed by a proline residue and (ii) an increase in the trans content of the prolyl bonds due to the presence of guest residues. In terms of the latter, we found that the more guests added to the system, the larger the increase in the trans content of the prolyl bonds, which results in an effective increase in the PPII content of the peptide.

    This issue of EPJ D introduces a revised list of sections and subsections, designed in close collaboration with the whole editorial board. The aim of these modifications is to reflect more faithfully the wide diversity of activities covered by our journal. A new section is introduced. Entitled “Atomic and Molecular Collisions”, it covers a large range of activities, from atom/atom or atom/molecules collisions (including the very active field of ultra-cold collisions in laser-cooled atomic or molecular gases), to electron scattering and molecular reactivity. The creation of this section reflects the increased interest of the journal for molecular and collisional physics, already apparent in the recent extension of the editorial board competence in this direction. We very much hope that this community will react positively to this trend and become a major component of the journal's life. For the other sections, we have markedly revised the list of subheadings. We think it important to make it as detailed as possible, both to indicate that EPJ D aims at being a generalist journal for AMO physics and to help our authors to find easily the proper section for their submissions. There is of course no way to describe the whole field's activity in a few subheadings. They are all to be understood with the broadest meaning. This list is by no means an exclusive one. All theoretical or experimental papers connected to atomic, molecular, plasma, quantum or optical physics are welcome. This revised section list appears almost simultaneously with the new WEB portal to all EPJ journals (www.eurphysj.org), which will be online within a few weeks. It unites the material formerly presented on our publisher's WEB sites (EDP Sciences, SIF and Springer). All the journal contents are available there (and all WEB registrations are of course valid for this portal). We offer also a free access to the highlight papers (see our editorial, Eur. Phys. J.

    Full Text Available We’ve reached the end of another year of publication at EBLIP, my first at the helm as Editor‐in‐Chief, and four full years of publication since we began. This year was a busy one with several changes to the editorial team, the addition of more Editorial Advisors, and new evidence summary writers joining our team. Most importantly, the journal continues to grow and thrive, with more people than ever participating in its success. This year we added a new section called Using Evidence in Practice, and in this issue there are two articles in that section which provide practical examples of applying evidence in the workplace. Putting evidence into practice is what EBLIP is all about, so it is my hope that this new section makes the application of evidence based practice more concrete for readers. As we began working on issue 4.4, the Editorial Team decided that it would be a good idea to seek out an Editorial Intern to help with some of the tasks we never seem to get to, given that we are all volunteers. We see the internship as an opportunity to give a library and information studies student a chance to get involved with an open access journal and learn about publishing in library and information studies, which will hopefully benefit them as they begin their new career. The Editorial Intern will assist with marketing and promotion of the journal, soliciting potential manuscripts, and proofreading. They will also participate in all editorial meetings and general discussions. We anticipate that they will bring a wealth of enthusiasm and fresh ideas to our conversations so that EBLIP Editors can also continue to learn and grow by having a fresh set of eyes involved with our processes. It will certainly be a win‐win situation and a learning opportunity for all involved. We are pleased to announce that Andrea Baer has accepted the position of Editorial Intern and joined our team in mid‐November. Andrea is currently attending the University of

    As the successor to Professor Teruo Kishi, the former Editor-in-Chief of Science and Technology of Advanced Materials (STAM), I would like to share some of STAM's journal history with our readers. STAM was launched in 2000 with the financial support of the Japanese Ministry of Education, Culture, Sports, Science and Technology in recognition of a strong need for an international journal that would be distributed and read across the globe. Five years later, the publication of STAM was transferred to the National Institute for Materials Science (NIMS) under the initiative of Professor Kishi. As a result of his work, STAM is now positioned as a high-impact journal, 3.512 as listed by the ISI 2011 Science Citation Index Journal Citation Report, with a much higher and faster growth than when I was participating as a co-founder in the past. STAM is well known as a successful open-access journal since shifting from the initial subscription model in 2008. As an editor, I would like to emphasize that STAM will continue to publish with a sense of social mission as an academic journal, allowing space for researchers to contribute to the sustainable development of society and health. However, some contribution from authors would assist us in creating a sustainable journal publishing model, and further enhance services to authors and readers of STAM. With this in mind, I would like to state that STAM's editorial board is planning to introduce an article processing charge from July 2013, in addition to NIMS' continuing financial support. One of our new editorial policies is to aim for reader-oriented publishing. I believe that academic journal publishing can take the role of navigator in advancing the development of materials. Among the many other scientific journals, STAM will lead the rapid growth in materials science, inspiring research into new materials for the future and leading the next generation of materials science and technology. It is my honor to work with members of

  11. Foreign Guests in Ancient Greece

    Full Text Available Xenía was a special relationship between a foreign guest and his host in Ancient Greece. The ritual of hosting a foreigner included an exchange of objects, feasting, and the establishment of friendship between people from different social backgrounds. This relationship implied trust, loyalty, friendship, and mutual aid between the people involved. Goods and services were also exchanged without any form of payment. There were no formal laws governing xenía – it was based entirely on a moral appeal. Mutual appreciation between the host and the guest was established during the ritual, but the host did retain a certain level of superiority over the guest. Xenía was one of the most important institutions in Ancient Greece. It had a lot of features and obligations similar to kinship and marriage. In literary sources the word xénos varies in meaning from “enemy stranger”, “friendly stranger”, “foreigner”, “guest”, “host” to “ritual friend”, and it is often hard to tell which usage is appropriate in a given passage. The paper describes the emphasis on hospitality towards foreigners. It presents an example of a depiction indicating xenía is presented, as well as several objects which were traded during the ritual. The paper also addresses the importance of hospitality in Greek drama in general, especially with examples of violations of the hospitality code.

    Full Text Available he paper considers the ambiguity of the term ‘guest worker’, based on the example of economic migrants who belong to the Roma population. Over the last fifty years, members of the Roma minority have migrated to Western European countries for different reasons (economic, political and social reasons, and there is no official data on the precise number of Roma who have migrated abroad, whether permanently or temporarily. It is possible to establish a number of categories of Roma immigrants who reside permanently or temporarily in Western European countries. These are: the so-called “classic guest workers” who, through legal or illegal means went to work abroad in the 60’s and 70’s, and mostly settled permanently in the host countries; Roma refugees from Kosovo and/or asylum seekers who left the country during the wars in the 90’s, and who were returned to Serbia after the signing of the Readmission treaty; and those Roma who represent occasional economic migrants: people who, after Serbia was put on the white Schengen list (the liberalization of the visa policy for citizens of Serbia, spend three months at a time working abroad. Even though these three categories of Roma workers have different reasons for migrating from and returning to Serbia, the majority of the population perceives them as a unified, distinct whole – as guest workers. The paper is the result of fieldwork conducted in South-Eastern Serbia, in the village of Minicevo.

  13. Rotaxane and catenane host structures for sensing charged guest species.

    2014-07-15

    CONSPECTUS: The promise of mechanically interlocked architectures, such as rotaxanes and catenanes, as prototypical molecular switches and shuttles for nanotechnological applications, has stimulated an ever increasing interest in their synthesis and function. The elaborate host cavities of interlocked structures, however, can also offer a novel approach toward molecular recognition: this Account describes the use of rotaxane and catenane host systems for binding charged guest species, and for providing sensing capability through an integrated optical or electrochemical reporter group. Particular attention is drawn to the exploitation of the unusual dynamic properties of interlocked molecules, such as guest-induced shuttling or conformational switching, as a sophisticated means of achieving a selective and functional sensor response. We initially survey interlocked host systems capable of sensing cationic guests, before focusing on our accomplishments in synthesizing rotaxanes and catenanes designed for the more challenging task of selective anion sensing. In our group, we have developed the use of discrete anionic templation to prepare mechanically interlocked structures for anion recognition applications. Removal of the anion template reveals an interlocked host system, possessing a unique three-dimensional geometrically restrained binding cavity formed between the interlocked components, which exhibits impressive selectivity toward complementary anionic guest species. By incorporating reporter groups within such systems, we have developed both electrochemical and optical anion sensors which can achieve highly selective sensing of anionic guests. Transition metals, lanthanides, and organic fluorophores integrated within the mechanically bonded structural framework of the receptor are perturbed by the binding of the guest, with a concomitant change in the emission profile. We have also exploited the unique dynamics of interlocked hosts by demonstrating that an

    2009-08-06

    The host-guest chemistry of dendrimer-drug complexes is investigated by NMR techniques, including (1)H NMR and 2D-NOESY studies. The effects of molecular properties of drug molecules (protonation ability and spatial steric hindrance of charged groups) and surface functionalities of dendrimers (positively charged amine groups and negatively charged carboxylate groups) on the host-guest interactions are discussed. Different interaction mechanisms between dendrimers and drug molecules are proposed on the basis of NMR results. Primary amine- and secondary amine-containing drugs preferentially bind to negatively charged dendrimers by strong electrostatic interactions, whereas tertiary amine and quaternary ammonium-containing drugs have weak binding ability with dendrimers due to relatively low protonation ability of the tertiary amine group and serious steric hindrance of the quaternary ammonium group. Positively charged drugs locate only on the surface of negatively charged dendrimers, whereas negatively charged drugs locate both on the surface and in the interior cavities of positively charged dendrimers. The host-guest chemistry of dendrimer-drug complexes is promising for the development of new drug delivery systems.

  15. Theoretical model estimation of guest diffusion in Metal-Organic Frameworks (MOFs)

    KAUST Repository

    Zheng, Bin

    2015-08-11

    Characterizing molecule diffusion in nanoporous matrices is critical to understanding the novel chemical and physical properties of metal-organic frameworks (MOFs). In this paper, we developed a theoretical model to fastly and accurately compute the diffusion rate of guest molecules in a zeolitic imidazolate framework-8 (ZIF-8). The ideal gas or equilibrium solution diffusion model was modified to contain the effect of periodical media via introducing the possibility of guests passing through the framework gate. The only input in our model is the energy barrier of guests passing through the MOF’s gate. Molecular dynamics (MD) methods were employed to gather the guest density profile, which then was used to deduce the energy barrier values. This produced reliable results that require a simulation time of 5 picoseconds, which is much shorter when using pure MD methods (in the billisecond scale) . Also, we used density functional theory (DFT) methods to obtain the energy profile of guests passing through gates, as this does not require specification of a force field for the MOF degrees of freedom. In the DFT calculation, we only considered one gate of MOFs each time; as this greatly reduced the computational cost. Based on the obtained energy barrier values we computed the diffusion rate of alkane and alcohol in ZIF-8 using our model, which was in good agreement with experimental test results and the calculation values from standard MD model. Our model shows the advantage of obtaining accurate diffusion rates for guests in MOFs for a lower computational cost and shorter calculation time. Thus, our analytic model calculation is especially attractive for high-throughput computational screening of the dynamic performance of guests in a framework.

  20. Force and Stress along Simulated Dissociation Pathways of Cucurbituril-Guest Systems.

    Science.gov (United States)

    Velez-Vega, Camilo; Gilson, Michael K

    2012-03-13

    The field of host-guest chemistry provides computationally tractable yet informative model systems for biomolecular recognition. We applied molecular dynamics simulations to study the forces and mechanical stresses associated with forced dissociation of aqueous cucurbituril-guest complexes with high binding affinities. First, the unbinding transitions were modeled with constant velocity pulling (steered dynamics) and a soft spring constant, to model atomic force microscopy (AFM) experiments. The computed length-force profiles yield rupture forces in good agreement with available measurements. We also used steered dynamics with high spring constants to generate paths characterized by a tight control over the specified pulling distance; these paths were then equilibrated via umbrella sampling simulations and used to compute time-averaged mechanical stresses along the dissociation pathways. The stress calculations proved to be informative regarding the key interactions determining the length-force profiles and rupture forces. In particular, the unbinding transition of one complex is found to be a stepwise process, which is initially dominated by electrostatic interactions between the guest's ammoniums and the host's carbonyl groups, and subsequently limited by the extraction of the guest's bulky bicyclooctane moiety; the latter step requires some bond stretching at the cucurbituril's extraction portal. Conversely, the dissociation of a second complex with a more slender guest is mainly driven by successive electrostatic interactions between the different guest's ammoniums and the host's carbonyl groups. The calculations also provide information on the origins of thermodynamic irreversibilities in these forced dissociation processes.

  1. Guest-host chemistry with dendrimers—binding of carboxylates in aqueous solution

    DEFF Research Database (Denmark)

    Ficker, Mario; Petersen, Johannes Fabritius; Hansen, Jon Stefan

    2015-01-01

    Recognition and binding of anions in water is difficult due to the ability of water molecules to form strong hydrogen bonds and to solvate the anions. The complexation of two different carboxylates with 1-(4-carbomethoxypyrrolidone)-terminated PAMAM dendrimers was studied in aqueous solution using...... the carboxylate-dendrimer interaction selectively. The binding stoichiometry for 3-hydroxy-2-naphthoate was found to be two strongly bound guest molecules per dendrimer and an additional 40 molecules with weak binding affinity. The NOESY NMR showed a clear binding correlation of sodium 3-hydroxy-2-naphthoate...... with the lyophilic dendrimer core, possibly with the two high affinity guest molecules. In comparison, sodium 2-naphthoate showed a weaker binding strength and had a stoichiometry of two guests per dendrimer with no additional weakly bound guests. This stronger dendrimer interaction with sodium 3-hydroxy-2...

  2. Computations between metallocalix(4)arene host and a series of four oil-based fuel pollutant guests

    International Nuclear Information System (INIS)

    Pathak, D.A.; Street, N.C.

    2006-01-01

    Calculations using PM3 and mechanics methods on metallocalix(4)arene hosts (1-10) and substituted dibenzothiophene guests (A-D), which are generally known as oil-based fuel pollutants, show that host-guest formation is energetically favored. Calculations have been carried out for both 1/1 and 1/4 ratios of host/guest. There is no direct bonding between the metal center of the host and the sulfur of the guest in the host-guest complex. Sterically hundered dibenzothiophene guests show similar energies to the unhindered analogs. For calix(4)arenas (5-10) in partial cone conformations and having hydrogen rather than p-tert-butyl groups on the wide rim, host-guest formation occurs within the narrow rim rather than the wide rim. Host-guest association appears to occur via Pie-Pie interactions between host and guest phenyl groups rather than via metal-sulfur bonding. The study has importance especially in oil refining to obtain environmentally safe fuel oils and help supramolecular chemists in designing and synthesizing more sophisticated host molecules for the removal of sulfur from crude oil / refinery oil.

  6. Selecting non-classified hotels in Kenya: what really matters for business guests?

    Directory of Open Access Journals (Sweden)

    Alex K Kivuva

    2014-01-01

    Full Text Available Non-classified hotels, which comprise small hotels and guest houses, are important accommodation providers offering limited services and products as compared to the classified hotels. Through guest satisfaction, they can achieve repeat business and also get new business through word of mouth from previous guests. The main focus is for the hoteliers to know exactly the determinants of selection of hotels by their guests. In this case, the focus was on non-classified hotels in Mtwapa town at the Kenyan coast. The study adopted a cross-sectional descriptive survey design. Results from this study clearly indicate that all aspects of hotel operations are important to business guests’ selection of a non-classified hotel. However, it was revealed that this was not on equal basis. Results indicate that the core product (guestroom comfortability, hygiene and cleanliness were the most important factors in determining guests’ selection of where to stay. This research therefore suggests that any efforts towards quality improvement in a hotel should focus primarily on ensuring customer satisfaction with the guestroom. While acknowledging the importance of all aspects of hotel operations, managers should recognize the importance of the guestroom and its facilities towards hotel selection and overall customer satisfaction. Therefore, it is imperative that managers channel their resources towards improving guest services in the guestrooms in accordance with the requirements of the clientele. This includes such aspects as the look of the guest rooms, facilities provided in the guest rooms and comfortability of the bed and mattress.

Frequent restaurant visits are not only the reflection of satisfying hedonistic needs, but also the result of increasing number of single-person households as well as adjustment to the European business hours.In an increasingly competitive environment, restaurants must be focused on guests using marketing concepts that identify their needs thus leading to their satisfaction and increased retention.Service quality is fundamental component which produce higher levels of guest satisfaction, which in turn lead to higher sales revenue.The main purpose of this study was to examine the quality dimensions that affect guest satisfaction in restaurant industry. Food and beverage quality, the quality of service delivery, physical environment and price fairness are analyzed as a key components of restaurant experience. The results could be helpful tool for restaurant managers to invest their resources more efficiently, making changes to crucial quality attributes that elicit the guests’ satisfaction level. A management approach focused on guest satisfaction can improve restaurant business performance.

    Yang, Ying-Wei; Sun, Yu-Long; Song, Nan

    2014-07-15

    CONSPECTUS: For device miniaturization, nanotechnology follows either the "top-down" approach scaling down existing larger-scale devices or the "bottom-up' approach assembling the smallest possible building blocks to functional nanoscale entities. For synthetic nanodevices, self-assembly on surfaces is a superb method to achieve useful functions and enable their interactions with the surrounding world. Consequently, adaptability and responsiveness to external stimuli are other prerequisites for their successful operation. Mechanically interlocked molecules such as rotaxanes and catenanes, and their precursors, that is, molecular switches and supramolecular switches including pseudorotaxanes, are molecular machines or prototypes of machines capable of mechanical motion induced by chemical signals, biological inputs, light or redox processes as the external stimuli. Switching of these functional host-guest systems on surfaces becomes a fundamental requirement for artificial molecular machines to work, mimicking the molecular machines in nature, such as proteins and their assemblies operating at dynamic interfaces such as the surfaces of cell membranes. Current research endeavors in material science and technology are focused on developing either a new class of materials or materials with novel/multiple functionalities by shifting host-guest chemistry from solution phase to surfaces. In this Account, we present our most recent attempts of building monolayers of rotaxanes/pseudorotaxanes on surfaces, providing stimuli-induced macroscopic effects and further understanding on the switchable host-guest systems at interfaces. Biocompatible versions of molecular machines based on synthetic macrocycles, such as cucurbiturils, pillararenes, calixarenes, and cyclodextrins, have been employed to form self-assembled monolayers of gates on the surfaces of mesoporous silica nanoparticles to regulate the controlled release of cargo/drug molecules under a range of external stimuli

  10. Distribution of metal and adsorbed guest species in zeolites

    Energy Technology Data Exchange (ETDEWEB)

    Chmelka, B.F.

    1989-12-01

    Because of their high internal surface areas and molecular-size cavity dimensions, zeolites are used widely as catalysts, shape- selective supports, or adsorbents in a variety of important chemical processes. For metal-catalyzed reactions, active metal species must be dispersed to sites within the zeolite pores that are accessible to diffusing reactant molecules. The distribution of the metal, together with transport and adsorption of reactant molecules in zeolite powders, are crucial to ultimate catalyst performance. The nature of the metal or adsorbed guest distribution is known, however, to be dramatically dependent upon preparatory conditions. Our objective is to understand, at the molecular level, how preparatory treatments influence the distribution of guest species in zeolites, in order that macroscopic adsorption and reaction properties of these materials may be better understood. The sensitivity of xenon to its adsorption environment makes {sup 129}Xe NMR spectroscopy an important diagnostic probe of metal clustering and adsorbate distribution processes in zeolites. The utility of {sup 129}Xe NMR depends on the mobility of the xenon atoms within the zeolite-guest system, together with the length scale of the sample heterogeneity being studied. In large pore zeolites containing dispersed guest species, such as Pt--NaY, {sup 129}Xe NMR is insensitive to fine structural details at room temperature.

    Full Text Available The aim of this study was to investigate guest profiles at a hotel that has created a best-practices water management model to determine how different types of guests contribute to saving water during their stay. To do this, we analyzed levels of environmental awareness and pro-environmental behavior among the guests. Information was gathered through 648 structured surveys with guests at Hotel Samba in the Spanish seaside resort of Lloret de Mar between September 2015 and August 2016. Cluster analysis revealed four profiles of guests with different sociodemographic characteristics and different levels of awareness and proactivity in relation to water conservation. We combined our findings to develop a framework that illustrates how the two dimensions of environmental awareness and pro-environmental behavior are related in this setting. This article provides new insights into how hotel guests’ environmental awareness and engagement can influence a hotel’s water-saving efforts. These insights should help hotel operators to devise new, guest-centered strategies for saving water.

  14. Incommensurate host-guest structures in compressed elements: Hume—Rothery effects as origin

    International Nuclear Information System (INIS)

    Degtyareva, V F

    2015-01-01

    Discovery of the incommensurate structure in the element Ba under pressure 15 years ago was followed by findings of a series of similar structures in other compressed elements. Incommensurately modulated structures of the host-guest type consist of a tetragonal host structure and a guest structure. The guest structure forms chains of atoms embedded in the channels of host atoms so that the axial ratio of these subcells along the c axis is not rational. Two types of the host-guest structures have been found so far: with the host cells containing 8 atoms and 16 atoms; in these both types the guest cells contain 2 atoms. These crystal structures contain a non-integer number of atoms in their unit cell: tI11* in Bi, Sb, As, Ba, Sr, Sc and tI19* in Na, K, Rb. We consider here a close structural relationship of these host-guest structures with the binary alloy phase Au 3 Cd 5 -tI32. This phase is related to the family of the Hume-Rothery phases that is stabilized by the Fermi sphere-Brillouin zone interaction. From similar considerations for alkali and alkaline-earth elements a necessary condition for structural stability emerges in which the valence electrons band overlaps with the upper core electrons and the valence electron count increases under compression.

  15. Structural Consequences of Anionic Host-Cationic Guest Interactions in a Supramolecular Assembly

    Pluth, Michael D.; Johnson, Darren W.; Szigethy, Geza; Davis, Anna V.; Teat, Simon J.; Oliver, Allen G.; Bergman, Robert G.; Raymond, Kenneth N.

    2008-07-09

    The molecular structure of the self-assembled supramolecular assembly [M{sub 4}L{sub 6}]{sup 12-} has been explored with different metals (M = Ga{sup III}, Fe{sup III}, Ti{sup IV}) and different encapsulated guests (NEt{sub 4}{sup +}, BnNMe{sub 3}{sup +}, Cp{sub 2}Co{sup +}, Cp*{sub 2}Co{sup +}) by X-ray crystallography. While the identity of the metal ions at the vertices of the M{sub 4}L{sub 6} structure is found to have little effect on the assembly structure, encapsulated guests significantly distort the size and shape of the interior cavity of the assembly. Cations on the exterior of the assembly are found to interact with the assembly through either {pi}-{pi}, cation-{pi}, or CH-{pi} interactions. In some cases, the exterior guests interact with only one assembly, but cations with the ability to form multiple {pi}-{pi} interactions are able to interact with adjacent assemblies in the crystal lattice. The solvent accessible cavity of the assembly is modeled using the rolling probe method and found to range from 253-434 {angstrom}{sup 3}, depending on the encapsulated guest. Based on the volume of the guest and the volume of the cavity, the packing coefficient for each host-guest complex is found to range from 0.47-0.67.

  16. Supramolecular chemistry at interfaces: host-guest interactions for fabricating multifunctional biointerfaces.

    2014-07-15

    CONSPECTUS: Host-guest chemistry can greatly improve the selectivity of biomolecule-ligand binding on account of recognition-directed interactions. In addition, functional structures and the actuation of supramolecular assemblies in molecular systems can be controlled efficiently through various host-guest chemistry. Together, these highly selective, strong yet dynamic interactions can be exploited as an alternative methodology for applications in the field of programmable and controllable engineering of supramolecular soft materials through the reversible binding between complementary components. Many processes in living systems such as biotransformation, transportation of matter, and energy transduction begin with interfacial molecular recognition, which is greatly influenced by various external stimuli at biointerfaces. Detailed investigations about the molecular recognition at interfaces can result in a better understanding of life science, and further guide us in developing new biomaterials and medicines. In order to mimic complicated molecular-recognition systems observed in nature that adapt to changes in their environment, combining host-guest chemistry and surface science is critical for fabricating the next generation of multifunctional biointerfaces with efficient stimuli-responsiveness and good biocompatibility. In this Account, we will summarize some recent progress on multifunctional stimuli-responsive biointerfaces and biosurfaces fabricated by cyclodextrin- or cucurbituril-based host-guest chemistry and highlight their potential applications including drug delivery, bioelectrocatalysis, and reversible adsorption and resistance of peptides, proteins, and cells. In addition, these biointerfaces and biosurfaces demonstrate efficient response toward various external stimuli, such as UV light, pH, redox chemistry, and competitive guests. All of these external stimuli can aid in mimicking the biological stimuli evident in complex biological environments

    Full Text Available Hotel companies which operate in today's competitive environment must constantly work on improving their products and services, at the request of their guests. Customer satisfaction is the key to retaining existing and attracting new guests. To achieve this goal, managers in the hotel organizations have become aware of the fact that the quality of staying in hotel represent unique experience for tourists. Lot of papers are dealing with the exploration of this topic, it only proves its importance nowadays. However, insufficient attention is paid to the simultaneous study of experience of guests and their satisfaction through the offered models (indexes that are created for this purpose. The purpose of this paper is to show the importance of these issues and identify their potential symbiosis.

  20. Energy-cascade organic photovoltaic devices incorporating a host-guest architecture.

    Science.gov (United States)

    Menke, S Matthew; Holmes, Russell J

    2015-02-04

    In planar heterojunction organic photovoltaic devices (OPVs), broad spectral coverage can be realized by incorporating multiple molecular absorbers in an energy-cascade architecture. Here, this approach is combined with a host-guest donor layer architecture previously shown to optimize exciton transport for the fluorescent organic semiconductor boron subphthalocyanine chloride (SubPc) when diluted in an optically transparent host. In order to maximize the absorption efficiency, energy-cascade OPVs that utilize both photoactive host and guest donor materials are examined using the pairing of SubPc and boron subnaphthalocyanine chloride (SubNc), respectively. In a planar heterojunction architecture, excitons generated on the SubPc host rapidly energy transfer to the SubNc guest, where they may migrate toward the dissociating, donor-acceptor interface. Overall, the incorporation of a photoactive host leads to a 13% enhancement in the short-circuit current density and a 20% enhancement in the power conversion efficiency relative to an optimized host-guest OPV combining SubNc with a nonabsorbing host. This work underscores the potential for further design refinements in planar heterojunction OPVs and demonstrates progress toward the effective separation of functionality between constituent OPV materials.

    Understanding guest diffusion in nanoporous host-guest systems is crucial in the efficient design of metal-organic frameworks (MOFs) for chemical separation and drug delivery applications. In this work, we investigated the effect of molecule length on the diffusion rate in the zeolitic imidazolate framework 8 (ZIF-8), trying to find a simple and straightforward variable to characterize the complicated guest diffusion. We found that, counter-intuitively, long guest molecules can diffuse as quickly as short molecules; the diffusion coefficient of ethyl acetate for example is of the same order of magnitude as ethane and ethanol, as excludes the existence of a simple relationship between molecule length and diffusion rate. This phenomenon is explained by a study of the contributions of intra- and inter-cage movement to overall transport. Steric confinement limits the degrees of freedom of long guest molecules, shortening their residence time and increasing the efficiency of radial diffusion. In contrast, shorter molecules meander within MOF cages, reducing transport. Furthermore, the energy barrier of inter-cage transport also does not exhibit a simple dependence on a guest molecule length, attributing to the effect of the type of functional group on diffusion. Guests over varying lengths were investigated by using theoretical methods, revealing that the guest diffusion in ZIF-8 depends on the number of contiguous carbon atoms in a molecule, rather than its overall length. Thus, we proposed simple criteria to predict arbitrary guest molecule diffusivity in ZIF-8 without time-consuming experimentation. © 2016 The Royal Society of Chemistry.

  7. Paramagnetic NMR investigation of dendrimer-based host-guest interactions.

    Directory of Open Access Journals (Sweden)

    Fei Wang

    Full Text Available In this study, the host-guest behavior of poly(amidoamine (PAMAM dendrimers bearing amine, hydroxyl, or carboxylate surface functionalities were investigated by paramagnetic NMR studies. 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO derivatives were used as paramagnetic guest molecules. The results showed that TEMPO-COOH significantly broaden the ¹H NMR peaks of amine- and hydroxyl-terminated PAMAM dendrimers. In comparison, no paramagnetic relaxation enhancement (PRE was observed between TEMPO-NH₂, TEMPO-OH and the three types of PAMAM dendrimers. The PRE phenomenon observed is correlated with the encapsulation of TEMPO-COOH within dendrimer pockets. Protonation of the tertiary amine groups within PAMAM dendrimers plays an important role during this process. Interestingly, the absence of TEMPO-COOH encapsulation within carboxylate-terminated PAMAM dendrimer is observed due to the repulsion of TEMPO-COO- anion and anionic dendrimer surface. The combination of paramagnetic probes and ¹H NMR linewidth analysis can be used as a powerful tool in the analysis of dendrimer-based host-guest systems.

    While it has long been known that some highly adsorbing microporous materials suddenly become inaccessible to guest molecules below certain temperatures, previous attempts to explain this phenomenon have failed. Here we show that this anomalous sorption behaviour is a temperature-regulated guest admission process, where the pore-keeping group's thermal fluctuations are influenced by interactions with guest molecules. A physical model is presented to explain the atomic-level chemistry and structure of these thermally regulated micropores, which is crucial to systematic engineering of new functional materials such as tunable molecular sieves, gated membranes and controlled-release nanocontainers. The model was validated experimentally with H2, N2, Ar and CH4 on three classes of microporous materials: trapdoor zeolites, supramolecular host calixarenes and metal-organic frameworks. We demonstrate how temperature can be exploited to achieve appreciable hydrogen and methane storage in such materials without sustained pressure. These findings also open new avenues for gas sensing and isotope separation.

    Synthetic macrocyclic host compounds can interact with suitable guest molecules via noncovalent interactions to form functional supramolecular systems. With the synergistic integration of the response of molecules and the unique properties at the nanoscale, nanoparticles functionalized with the host-guest supramolecular systems have shown great potentials for a broad range of applications in the fields of nanoscience and nanotechnology. In this review article, we focus on the applications of the nanoparticles functionalized with supramolecular host-guest systems in nanomedicine and healthcare, including therapeutic delivery, imaging, sensing and removal of harmful substances. A large number of examples are included to elucidate the working mechanisms, advantages, limitations and future developments of the nanoparticle-supramolecule systems in these applications.

    In this study, we aimed to investigate the effects cohesion of small surface-engineered guest binder particles on the flow behaviour of interactive mixtures. Polyvinylpyrrolidone (PVP) - a model pharmaceutical binder - was spray-dried with varying l-leucine feed concentrations to create small surface-engineered binder particles with varying cohesion. These spray-dried formulations were characterised by their particle size distribution, morphology and cohesion. Interactive mixtures were produced by blending these spray-dried formulations with paracetamol. The resultant blends were visualised under scanning electron microscope to confirm formation of interactive mixtures. Surface coverage of paracetamol by guest particles as well as the flow behaviour of these mixtures were examined. The flow performance of interactive mixtures was evaluated using measurements of conditioned bulk density, basic flowability energy, aeration energy and compressibility. With higher feed l-leucine concentrations, the surface roughness of small binder particles increased, while their cohesion decreased. Visual inspection of the SEM images of the blends indicated that the guest particles adhered to the surface of paracetamol resulting in effective formation of interactive mixtures. These images also showed that the low-cohesion guest particles were better de-agglomerated that consequently formed a more homogeneous interactive mixture with paracetamol compared with high-cohesion formulations. The flow performance of interactive mixtures changed as a function of the cohesion of the guest particles. Interactive mixtures with low-cohesion guest binder particles showed notably improved bulk flow performance compared with those containing high-cohesion guest binder particles. Thus, our study suggests that the cohesion of guest particles dictates the flow performance of interactive mixtures. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

    Field experiments on descriptive norms as a means to increase hotel guests' towel reuse [1] were replicated and extended. In two hotels in Germany (Study 1: N = 724; Study 2: N = 204), descriptive norm messages suggesting that 75% of guests had reused their towels, or a standard message appealing to environmental concerns, were placed in guests' bathrooms. Descriptive norm messages varied in terms of proximity of the reference group ("hotel guests" vs. "guests in this room") and temporal proximity (currently vs. two years previous). Reuse of towels was unobtrusively recorded. Results showed that reuse rates were high overall and that both standard and descriptive norm messages increased reuse rates compared to a no-message baseline. However, descriptive norm messages were not more effective than the standard message, and effects of proximity were inconsistent across studies. Discussion addresses cultural and conceptual issues in comparing the present findings with previous ones.

Some readers may feel that one or two subjects have not been represented, and for that I can only apologise. We did ask for contributions to several other topics (for example radiation metrology and optical techniques) but inevitably there were authors who for various reasons were unable to meet the deadline. Inevitably we will also have missed contributions from excellent potential authors (who satisfied the age criterion!). As Guest Editor I must bear the responsibility for those omissions. While page limits do not permit me to discuss the contributions to this issue individually I would like to mention the first contribution by Dr J E (Bob) Burns. Dr Burns was on the Editorial Board in the early sixties working with the second Editor, Professor Sir Joseph Rotblat. Both in his article and in personal communications Dr Burns has emphasized the important role of Professor Rotblat in the early years. I did write to Professor Rotblat seeking a contribution from him but, sadly, received a reply saying that he was not well enough to contribute `at present'; he died a few weeks later at the age of 96 years (please refer to www.pugwash.org for tributes from Mikhail Gorbachev, Kofi Annan and many others). Dr Burns wrote a short note to me shortly after his death including the following comment which is reproduced below: Although many people have contributed to the success of PMB over the last 50 years it was Rotblat's restless energy, power of persuasion and already existing fame (he was well known both scientifically and to the public at the time) that enabled him to rescue the journal from an early death.

    As revealed in previous empirical research, nurses describe their position in home-based nursing care (HBNC) as that of 'guests' in the patient's home. Such a description is problematic as 'guests' might not be considered to belong to the realm of professionalism. As Jacques Derrida's work on hospitality has received wide publicity, sparking theoretical and philosophical discussion about host and guest, the aim of this study was to explore how the concept 'guests' can be understood in the light of Derrida's philosophy of hospitality. The study revealed that (a) guest must be considered a binary concept; and (b) hospitality should be regarded as an exchange of giving and receiving between a host and a guest. The present study demonstrated that it is important to reflect on the meaning of the concepts used by nurses in HBNC. Further theoretical and empirical exploration of the concept 'hospitality' would be fruitful, i.e. what is patients' understanding of 'hospitality' and 'hostility' related to nurses' descriptions of themselves as 'guests' in the patient's home. © 2013 Blackwell Publishing Ltd.

    We used steady state optical spectroscopies such as photoluminescence and photoinduced absorption (PA), and magnetic-field PA (MPA) for studying the energy transfer dynamics in films and organic light emitting diodes (OLED) based on host–guest blends with different guest concentrations of the fluorescent polymer poly-[2-methoxy, 5-(2′-ethyl-hexyloxy)phenylene vinylene] (MEHPPV-host), and phosphorescent molecule PtII-tetraphenyltetrabenzoporphyrin [Pt(tpbp); guest]. We show that the energy transfer process between the excited states of the host polymer and guest molecule takes a ‘ping-pong’ type sequence, because the lowest guest triplet exciton energy, E T (guest), lies higher than that of the host, E T (host). Upon photon excitation the photogenerated singlet excitons in the host polymer chains first undergo a Förster resonant energy transfer process to the guest singlet manifold, which subsequently reaches E T (guest) by intersystem crossing. Because E T (guest)>E T (host) there is a subsequent Dexter type energy transfer from E T (guest) to E T (host). This energy transfer sequence has profound influence on the photoluminescence and electroluminescence emission spectra in both films and OLED devices based on the MEHPPV-Pt(tpbp) system. - Highlights: • We studied electroluminescence of OLEDs based on host–guest blends. • The emission efficiency decreases with the guest concentration. • We found a dominant Dexter energy transfer from the triplet(guest) to triplet(host). • Energy transfer occurs from the host to guest and back to the host again

  6. Recruiting Future Engineers Through Effective Guest Speaking In Elementary School Classrooms

    Energy Technology Data Exchange (ETDEWEB)

    Kevin Young

    2007-11-01

    In this paper, the author describes how engineers can increase the number of future engineers by volunteering as guest speakers in the elementary school classroom. The paper is divided into three main subjects. First, the importance of engineers speaking directly with young students is discussed. Next, several best practice techniques for speaking with young students are described. Finally, information on getting started as a guest speaker is presented, and a list of resources available to guest speakers is provided. The guest engineer speaking to an elementary school audience (ages 6-11) performs a critical role in encouraging young students to pursue a career in engineering. Often, he or she is the first engineer these students meet in person, providing a crucial first impression of the engineering career field and a positive visual image of what an engineer really looks like. A dynamic speaker presenting a well-delivered talk creates a lasting, positive impression on students, influencing their future decisions to pursue careers in engineering. By reaching these students early in life, the guest speaker will help dispel the many prevailing stereotypes about engineers which discourage so many students, especially young women, from considering this career. The guest speaker can ensure young students gain a positive first impression of engineers and the engineering career field by following some best practice techniques in preparing for and delivering their presentation. The author, an electrical engineer, developed these best practice techniques over the past 10 years while presenting over 350 talks on engineering subjects to elementary school students as a volunteer speaker with the U.S. Department of Energy, Idaho National Laboratory’s Speakers Bureau. Every engineer can make a meaningful contribution toward reversing the predicted shortfall of future engineers by volunteering to speak with young students at the elementary school level.

  7. A room with a viewpoint revisited: descriptive norms and hotel guests' towel reuse behavior.

    Directory of Open Access Journals (Sweden)

    Gerd Bohner

    Full Text Available Field experiments on descriptive norms as a means to increase hotel guests' towel reuse [1] were replicated and extended. In two hotels in Germany (Study 1: N = 724; Study 2: N = 204, descriptive norm messages suggesting that 75% of guests had reused their towels, or a standard message appealing to environmental concerns, were placed in guests' bathrooms. Descriptive norm messages varied in terms of proximity of the reference group ("hotel guests" vs. "guests in this room" and temporal proximity (currently vs. two years previous. Reuse of towels was unobtrusively recorded. Results showed that reuse rates were high overall and that both standard and descriptive norm messages increased reuse rates compared to a no-message baseline. However, descriptive norm messages were not more effective than the standard message, and effects of proximity were inconsistent across studies. Discussion addresses cultural and conceptual issues in comparing the present findings with previous ones.

  8. Vibrational spectroscopic and quantum theoretical study of host-guest interactions in clathrates: I. Hofmann type clathrates

    Directory of Open Access Journals (Sweden)

    2000-06-01

    Full Text Available Hofmann type clatharates are host-guest compounds with the general formula M(NH32M'(CN4·2G, in which M(NH32M'(CN4 is the host lattice and G is benzene, the guest molecule. In previous studies, host-guest interactions have been investigated by analyzing the RT and LNT vibrational (infrared, far infrared and Raman spectra of these clathrates. All the observed changes in the vibrational spectra of these clathrates are referred to a host-guest interaction originating from weak hydrogen bonding between the ammonia hydrogen atoms from the host lattice and the p electron cloud of the guest (benzene molecules. In order to obtain an insight into the relative importance of the local crystalline field vs. the anharmonicity effects on the spectroscopic properties of the guest species upon enclathration, as well as to explain the observed band shifts and splittings, several quantum theoretical approaches are proposed.

    Full Text Available Welcome to the first issue of our 5th volume of Evidence Based Library and Information Practice. And what an issue it is! We are very pleased to showcase the keynote addresses from the 5th International Evidence Based Library and Information Practice (EBLIP5 conference that took place in Stockholm, Sweden in July 2009. Andrew Booth, who was Chair of the International Program Committee for the conference, kindly agreed to take on a guest editorial role in gathering these keynote presentations together. I believe it is the first time the EBLIP community has been able to have the keynote papers from an EBLIP conference gathered in this way. Reading these commentaries will give you a true sense of the themes and questions that were woven throughout the conference and will give you lots to think about. For a fuller description and to put this Feature section in context, please be sure to read Andrew’s editorial at the beginning of the section.As we begin our fifth year of publication, submissions of original research articles continue to grow. In this issue we have five original articles on topics ranging from information literacy instruction to cataloguing of e‐books. Two articles look at using communities of practice in the support of evidence based practice; clearly this is an area of emerging research within EBLIP that readers will benefit from learning more about. One of these articles, by Urquhart, Brice, Cooper, Spink, and Thomas, won the Best Oral Presentation award at the EBLIP5 conference.In addition to the original research articles, we also have seven evidence summaries, covering topics such as unionization, information seeking behaviour, and the LIS blogosphere. The EBL101 column tackles critical appraisal, a daunting task that will not seem quite so scary once you’ve read the column! As well, in the Commentary section, Jessie McGowan and colleagues have contributed a checklist for the peer review of electronic search strategies

    In this study, similar to Hofmann type M(C 4 H 7 NH 2 ) 2 Ni(CN) 4 (M=Ni or Co) host and M(C 4 H 7 NH 2 ) 2 Ni(CN) 4 .nG (M=Ni or Co; G=benzene, 1,2-, 1,3-dichlorobenzene; n=the number of guest) hostguest compounds were obtained chemically. The infrared spectra of these compounds were recorded with FT-IR spectrometer in the spectroscopic region of 4000cm-1-400cm-1. From these spectra the vibrational wave numbers of ligand molecule, Ni(CN) 4 2 - ion and guest molecules were determined. The absorption and the liberation processes of the guest molecules in the host compounds were examined at room temperature by gravimetric method. Otherwise, it was seen that the molecular structure was supported by making instrumental analysis of host and some host-guest compounds. By analysing the structures of host and host-guest compounds were found to be similar to those of Hofmann type compounds, ligand molecule cyclobutylamine were coordinated to M metal atom from cyclobutylamine's nitrogen atom, the guest molecules were imprisoned in the structural cavities between the sheets

  15. Unanticipated guest motion during a phase transition in a ferroelastic inclusion compound.

    2002-03-13

    Urea inclusion compounds (UICs) have been used as tools to understand ferroelastic domain switching and molecular recognition during crystal growth. Although the vast majority of UICs contain helical arrangements of host H-bonds, those containing guests with the formula X(CH(2))(6)Y (X, Y = Br, Cl, CN, NC) adopt an alternative P2(1)/n packing mode in which the host molecules exist as stacked loops of urea hexamers. Such structures may be further separated into two classes, ones distorted away from hexagonal symmetry along [100] (Br(CH(2))(6)Br, Br(CH(2))(6)Cl, and Cl(CH(2))(6)Cl) and those distorted along [001] (e.g. NC(CH(2))(6)CN). In each of these systems, guests exist as equilibrium mixtures of gauche conformers whose populations control the direction and magnitude of the observed distortion. Such UICs are potentially ferroelastic, but the n-glide requires that domains are not related by a simple rotation-translation mechanism as in the helical systems. Ferroelastic (degenerate) domain reorientation would necessitate a large-scale reorganization of the urea framework and rupture of numerous H-bonds. Coupled with distortions of 2 to 10%, this mechanism-based barrier to domain switching has precluded observation of this phenomenon. To prepare ferroelastic UICs with minimal distortions from hexagonal symmetry, attempts were made to form solid solutions of UICs containing guests from the two classes. This failed, however: solid solution formation of the stacked loop form is usually possible within a series (e.g. with Cl(CH(2))(6)Cl and Br(CH(2))(6)Br), but not between series (e.g. Cl(CH(2))(6)Cl and NC(CH(2))(6)CN). Crystals of Cl(CH(2))(6)CN/urea, in which a single guest contains substituents from each class, are distorted along [001] by only 0.5% from hexagonal symmetry at 298 K and exhibit ferroelastic domain reorientation at high forces. At -66 degrees C, Cl(CH(2))(6)CN/urea undergoes a topotactic phase transition that is unexpectedly nontopochemical. The

    This article investigates user experiences with editorial control in online newspaper comment fields following the public backlash against online comments after the 2011 terror attacks in Norway. We analyze data from a survey of online news consumers focusing on experiences and attitudes towards...... editorial control set against a spectrum between “interventionist” and “noninterventionist” positions. Results indicate that interventionist respondents rate the quality of online comments as poor, whereas noninterventionist respondents have most often experienced being the target of editorial control...... measures and feel that editorial control has intensified after the terror attacks. We conclude that newspapers should pay attention to the different needs of participants when devising strategies for editorial control.

    A general approach toward the light-induced guest release from cucurbit[7]uril by means of a photoactivatable competitor was devised. An o-nitrobenzyl-caged competitor is photolyzed to generate a competitive guest that can displace cargo from the host macrocycle solely based on considerations of chemical equilibrium. With this method the release of terpene guests from inclusion complexes with cucurbit[7]uril was demonstrated. The binding of the herein investigated terpenes, all being lead fragrant components in essential oils, has been characterized for the first time. They feature binding constants of up to 10 8  L mol -1 and a high differential binding selectivity (spanning four orders of magnitude for the binding constants for the particular set of terpenes). By fine-tuning the photoactivatable competitor guest, selective and also sequential release of the terpenes was achieved. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

For the publication of the technical-scientific knowledge generated in the Institution, and by other researchers in forestry, the Revista Ciência Florestal was created, in 1991, as a result of the combined effort between the University and the private forest sector. The difficulties found in the early number were slowly overcome, with the effective participation of all segments, always looking of the improvement of the scientific and editorial quality, compartible with the qualitative growth goals of the journal. In this context, the incorporation of nationally renown researchers to the editorial board turned the scientific consulting more selective. The first important recognition of this journal happened with its indexing by the CAB International System, from England, in 1997. The repercussion of the inclusion on the indexing system was felt by the significant increase in the number of manuscripts received. To meet this new challenge, and the demand by the Braxilian scientific community, the Editorial Board decided to implement a second number of the journal, making it biannual this year. Thus, the edition of the ninth volume will comprise this first number, in the month of June, and a second one, planned forDecember 1999. Another change, to catch your eyes, is the cover of the Journal, bringing a new style. The design was developed by the Visual Programming Laboratory, of the Center for the Arts and Literature od the UFSM, substantially changing its layout, and giving it a more modern and actual appeal. The innovation will be complemented by a different picture in each volume. CEPEF hopes to modernize its Journal of scientific

    Full Text Available New host-guest materials have been prepared by incorporation of a home-made organic probe displaying a pyrene motif and a phosphonate function into a regular amphiphilic copolymer. Using powder X-Ray diffraction, photoluminescence and FT-IR spectroscopy, we have been able to study the non-covalent interactions between the host matrix and the guest molecule in the solid state. Interestingly, we have shown that the matrix directs the guest spatial localization and alters its properties. Thanks to the comparison of pyrene vs. N-pyrenylmaleimide derivatives, the influence of the chemical nature of the guest molecules on the non-covalent interactions with the host have been studied. In addition, using polyethylene glycol as a reference host, we have been able to evidence a true matrix effect within our new insertion materials. The phosphonated guest molecule appears to be a novel probe targeting the hydrophilic domain of the host copolymer.

    2016-03-15

    The powerful host-guest chemistry of cucurbit[8]uril (CB[8]) was employed to obtain photoresponsive polyelectrolyte multilayer films for the reversible and photocontrolled binding and release of an organic guest molecule. For this purpose, we designed and synthesized a polyelectrolyte with azobenzene side groups. Then, CB[8] was associated with the azo side group to obtain a supramolecular host-guest complex that was further used as building block in order to prepare photoresponsive and CB[8]-containing polyelectrolyte multilayer films. Ultraviolet spectroscopy and a dissipative quartz crystal microbalance are employed to monitor the formation of the host-guest complex and the layer-by-layer self-assembly of the multilayer films, respectively. We demonstrate that the photoresponsive properties of the azo side groups are maintained before and after host-guest complexation with CB[8] in solution and within the multilayer films, respectively. A guest molecule was then specifically included as second binding partner into the CB[8]-containing multilayer films. Subsequently, the release of the guest was performed by UV light irradiation due to the trans-cis isomerization of the adjacent azo side groups. Re-isomerization of the azo side groups was achieved by VIS light irradiation and enabled the rebinding of the guest into CB[8]. Finally, we demonstrate that the photocontrolled binding and release within CB[8]-containing multilayer films can reliably and reversibly be performed over a period of more than 2 weeks with constant binding efficiency. Therefore, we expect such novel type of photosensitive films to have promising future applications in the field of stimuli-responsive nanomaterials.

    Host–guest interactions between the aromatic molecules benzene, toluene, aniline and nitrobenzene and the redox-active TCNQ-based metal–organic framework (MOF), Fe(TCNQ)(4,4'-bpy) (1) (TCNQ = 7,7,8,8-tetracyanoquinodimethane), have been found to modulate spontaneous magnetization behaviours at low temperatures. An analogous MOF, Mn(TCNQ)(4,4'-bpy) (2) with isotropic Mn(II) ions as well as the two-dimensional compound Fe(TCNQ)(DMF)2·2DMF (3·2DMF), were also prepared as models for studying the effects of single-ion magnetic anisotropy and structural distortion on spin canting. The results indicate guest-dependent long range magnetic ordering occurs at low temperatures, which correlates with the electrostatic and steric effects of the incorporated aromatic guests.

  10. Engineering responsive polymer building blocks with host-guest molecular recognition for functional applications.

    2014-07-15

    CONSPECTUS: All living organisms and soft matter are intrinsically responsive and adaptive to external stimuli. Inspired by this fact, tremendous effort aiming to emulate subtle responsive features exhibited by nature has spurred the invention of a diverse range of responsive polymeric materials. Conventional stimuli-responsive polymers are constructed via covalent bonds and can undergo reversible or irreversible changes in chemical structures, physicochemical properties, or both in response to a variety of external stimuli. They have been imparted with a variety of emerging applications including drug and gene delivery, optical sensing and imaging, diagnostics and therapies, smart coatings and textiles, and tissue engineering. On the other hand, in comparison with molecular chemistry held by covalent bonds, supramolecular chemistry built on weak and reversible noncovalent interactions has emerged as a powerful and versatile strategy for materials fabrication due to its facile accessibility, extraordinary reversibility and adaptivity, and potent applications in diverse fields. Typically involving more than one type of noncovalent interactions (e.g., hydrogen bonding, metal coordination, hydrophobic association, electrostatic interactions, van der Waals forces, and π-π stacking), host-guest recognition refers to the formation of supramolecular inclusion complexes between two or more entities connected together in a highly controlled and cooperative manner. The inherently reversible and adaptive nature of host-guest molecular recognition chemistry, stemming from multiple noncovalent interactions, has opened up a new platform to construct novel types of stimuli-responsive materials. The introduction of host-guest chemistry not only enriches the realm of responsive materials but also confers them with promising new applications. Most intriguingly, the integration of responsive polymer building blocks with host-guest recognition motifs will endow the former with

    Full Text Available Authors demonstrate the use of cluster analysis in finding out (ascertaining the homogenity/heterogenity of guests as to the degree of their demand. The degree of guests’ demand is defined according to the importance of perceived service quality components measured by SERVQUAL, which was adopted and adapted, according to the specifics of health spa industry in Slovenia. Goals of the article are: (a the identification of the profile of importance of general health spa service quality components, and (b the identification of groups of guests (segments according to the degree of their demand in the research in 1991 compared with 1999. Cluster analysis serves as useful tool for guest segmentation since it reveals the existence of important differences in the structure of guests in the year 1991 compared with the year 1999. The results serve as a useful database for management in health spas.

    A lamellar liquid crystal (LC) phase of certain bent-core mesogenic molecules can be grown in a manner that generates a single chiral helical nanofilament in each of the cylindrical nanopores of an anodic aluminum oxide (AAO) membrane. By introducing guest molecules into the resulting composite chiral nanochannels, we explore the structures and functionality of the ordered guest/host LC complex, verifying the smectic-like positional order of the fluidic nematic LC phase, which is obtained by the combination of the LC organization and the nanoporous AAO superstructure. The guest nematic LC 4'- n -pentyl-4-cyanobiphenyl is found to form a distinctive fluid layered ordered LC complex at the nanofilament/guest interface with the host 1,3-phenylene bis[4-(4-nonyloxyphenyliminomethyl)benzoate], where this interface contacts the AAO cylinder wall. Filament growth form is strongly influenced by mixture parameters and pore dimensions.

    The close of a 5-year editorship gives opportunity to reflect on the highs and the lows of an editorship. The goal of such reflection is to assist both authors and reviewers in interacting with a biomedical journal, and to foster interest among individuals contemplating an editorship. Among the highs was the privilege of publishing high-quality original scientific work within the scope of the journal; in this instance mechanistic studies of disease. Although review articles and editorials have their reward, it is the publication of original peer-reviewed work that constitutes the true basis for advancing biomedical science. This is the heart of journal publication. Second, the editorial interaction with submitting authors in bringing their work to publication is itself highly rewarding, and can lead to longer-term collegial working relationships between editors and authors. The anonymous expert reviewers also play a key role in bringing outstanding scientific work to successful publication. Collectively, authors, editors, and reviewers constitute an important 'community of science'. Third, working together as an editorial team, especially through the weekly 'journal clubs' that a regular editorial meeting affords, is commended as a key reward of any editorial group taking on journal management. The lows included sifting through submitted manuscripts in which the rigor of science was not satisfactory, and encountering specific instances of compromised scientific integrity--fortunately rare. In both instances, the editorial commitment is to publish high-quality original science; a necessary corollary is identifying those submissions, through rigorous but fair review, which do not meet journal standards. In the end, editorship is a highly rewarding experience, and very much conducive to sustaining the wonder of science that drew us to this profession.

    2017-10-01

    In this commentary, I review 38 articles published as editorials in Simulation in Healthcare from inception to April 2016. Of the 27 authors, there was a predominance of medical doctors (63%), male authors (67%), and work originating in the United States (86%). The founding Editor-in-Chief Dr David Gaba contributed to half of the editorials. Using inductive thematic analysis, the following five themes were identified: "embedding" simulation, simulation responding to clinical practice, educational considerations for simulation, research practices, and communicating leadership and scholarship about the community. After thematic analysis, the theoretical notion of communities of practice was used to make further meaning of the themes. This theorizing process reveals that editorial content aligns with the features of an evolving community of practice. The editorials seem to have responded to and shaped contemporary simulation practices. The editorial is a powerful forum in which to frame issues relevant to the healthcare simulation community. As the founding Editor-in-Chief, Gaba has made an extraordinary contribution to the Society for Simulation in Healthcare, in these editorials and the broader healthcare simulation community. Under the leadership of the Editor-in-Chief, Dr Mark Scerbo, I am confident that the editorial voice will continue in the true spirit of scholarship.

    Full Text Available Welcome to the December issue of EBLIP, the final issue of my first year as Editor-in-Chief. A year which I have thoroughly enjoyed and one where the fears over what to write in my editorials haven’t materialised. This quarter, ethics has featured quite heavily in my working life so I decided to make this the topic of the editorial, sharing some of my thoughts regarding evidence, ethics and how ethical principles are implemented within the EBLIP journal.Ethics are “principles of conduct or standards of behaviour governing an individual or profession” (Library and Information Science Editorial Committee, 2010, and as individuals or professionals we may be governed by various ethical codes. As I'm sure you know, EBLIP originated in the health domain, where ethical values and ethical research feature strongly. Indeed, by its formal definition, research cannot take place unless “ethical approval” from an appropriate committee has been granted. The practicalities of taking research through the ethical approval process can often be time consuming, and those involved in research need to bear this in mind when planning a project. Each committee will have a slightly different form and process (which can add to the frustration of the researcher, but basically will make their decision to approve on the basis that the research includes obtaining informed consent from participants (i.e., participants know what the research is about and what their involvement will mean; that the research will not cause harm to participants; that confidentiality will be maintained; and that the research undertaken is methodologically rigorous and worthwhile. Preparing a proposal for ethical approval, whilst time consuming, makes the researcher think about all aspects of the research and how it is going to be operationalized, which can save lots of time and effort in the long run and may well also improve the research design. These principles are the same whatever

    Full Text Available The effect of polyphosphate (polyP microparticles on wound healing was tested both in vitro and in a mice model in vivo. Two approaches were used: pure salts of polyphosphate, fabricated as amorphous microparticles (MPs, consisting of calcium and magnesium salts of polyP, “Ca–polyp-MPs” and “Mg–polyp-MPs”, and host–guest composite particles, prepared from amorphous collagen (host and polyphosphate (guest, termed “col/polyp-MPs”. Animal experiments with polyP on healing of excisional wounds were performed using both normal mice and diabetic mice. After a healing period of 7 days “Ca–polyp-MP” significantly improved re-epithelialization in normal mice from 31% (control to 72% (polyP microparticle-treated. Importantly, in diabetic mice, particularly the host–guest particles “col/polyp-MP”, increased the rate of re-epithelialization to ≈40% (control, 23%. In addition, those particles increased the expression of COL-I and COL-III as well as the expression the α-smooth muscle actin and the plasminogen activator inhibitor-1. We propose that “Ca–polyp-MPs”, and particularly the host–guest “col/polyp-MPs” are useful for topical treatment of wounds.

    Full Text Available A lot of marketing experts in catering, restaurants especially, have recently been preoccupied by measuring the service quality. Business in competitive and turbulent surrounding requires that restaurants continually improve their products, which is based on guests specific demands and wishes. Comprehension of how consumers see catering offer and research on factors that determine consumers satisfaction are the key for achieving business aims. The aim of this study is an identification of key components of service qualities which restaurants and their influence on guests satisfaction offer. Measures of descriptive statistics, explorative factor and multiple regressive analysis were used in order to achieve the aims of the research. The facts were collected by using the survey. Results of the research highlight 3 key elements of the service quality that restaurants offer and those are: professionalism of personnel, understanding of guests, paying individual attention and meeting specific demands. The first two components include attributes that evince statistically important influence on guests satisfaction. Finds of conducted survey help managers and restaurateurs determine factors they will focus on during the making marketing strategy which will supply high level of consumers satisfaction on one side, and long-term profitability on the other side.

    Neurosciences continues to be the leading journal for Neurosciences in Saudi Arabia and the Middle East. In January 2007, Neurosciences was indexed by Thomson ISI in Science Citation Index Expanded online at ISI Web of KnowledgeSM and Neurosciences Citation Index. Since then a significantly increased volume of scientific articles continues to be submitted to the journal by enthusiastic authors, a fact that enriches the scientific contents of the journal. In 2008, we had a total number of website hits of 495,625 with a monthly average of 41,000. We received a total of 155 manuscripts, with a monthly average of 13 and an average rejection rate of 29%. From these, we published a total of 100 articles, totaling 523 pages for the entire volume. Forty-nine percent of these were original articles. Fifty-eight percent of published articles were from the Eastern Mediterranean Region (EMR), with 30% from KSA, 5% from the Gulf, and 23% from other Arab and EMR countries. The remaining 42% of published articles we received from Canada, India, Japan, Malaysia, and Turkey. The average time from received to acceptance of original articles was 4 months and 4.9 months for acceptance to publication. Reasons for rejection included unrelated topics, poor contents, or duplicate publication. In addition to our 4 regular issues in 2008, we published a supplement of abstracts presented at the 16th Saudi Neuroscience Symposium. We would like to thank the Editorial and Advisory Board Members for their significant contribution to maintain the standards of Neuroscience and looking forward to their important continued role in achieving our goals for 2009. In 2009, we aim to increase the number of issues to meet the increased load of manuscripts. Our objective is to enrich the scientific Neuroscience material presented by the journal with important topic reviews and regular neuroscience quizzes to achieve PubMed indexing.

    Low-temperature and high-pressure experiments were performed with filled ice Ih structure of methane hydrate under pressure and temperature conditions of 2.0 to 77.0 GPa and 30 to 300 K, respectively, using diamond anvil cells and a helium-refrigeration cryostat. Distinct changes in the axial ratios of the host framework were revealed by In-situ X-ray diffractometry. Splitting in the CH vibration modes of the guest methane molecules, which was previously explained by the orientational ordering of the guest molecules, was observed by Raman spectroscopy. The pressure and temperature conditions at the split of the vibration modes agreed well with those of the axial ratio changes. The results indicated that orientational ordering of the guest methane molecules from orientational disordered-state occurred at high pressures and low temperatures, and that this guest ordering led to the axial ratio changes in the host framework. Existing regions of the guest disordered-phase and the guest ordered-phase were roughly estimated by the X-ray data. In addition, above the pressure of the guest-ordered phase, another high pressure phase was developed at a low-temperature region. The deuterated-water host samples were also examined and isotopic effects on the guest ordering and phase changes were observed.

    Although there has been a continuous increase in the number of women working in the field of medicine, women rarely reach the highest academic positions as full professors or editorial board members. We aimed to determine the proportion of women on the editorial boards of top-ranked medical journals in different medical specialties. We analyzed the gender of editorial board members of 60 top-ranked journals of 12 Thomson Reuters Web of Knowledge Journal Citation Reports categories. A total of 4175 editors were included in our analysis. Only 15.9% (10 of 63) editors-in-chief were female. In the 5 categories, critical care, anesthesiology, orthopedics, ophthalmology and radiology, nuclear medicine and medical imaging, currently not 1 woman holds the position of editor-in-chief. Less than one fifth (17.5%, 719 of 4112) of all editorial board members were women. There were significant differences among the evaluated categories, with the highest percentage of women in the category of medicine, general and internal and the lowest in the category critical care, followed by orthopedics. In every category, the proportion of women as editorial board members was substantially lower than that of men. Women are underrepresented on the editorial boards of major medical journals, although there is a great variability among the journals and categories analyzed. If more women are nominated to serve on editorial boards, they will be a visible sign of continuing progress and serve as important role models for young women contemplating a career in academic medicine.

    Bibliometric mapping of scientific articles based on keywords and technical terms in abstracts is now frequently used to chart scientific fields. In contrast, no significant mapping has been applied to the full texts of non-specialist documents. Editorials in Nature and Science are such non-specialist documents, reflecting the views of the two most read scientific journals on science, technology and policy issues. We use the VOSviewer mapping software to chart the topics of these editorials. A term map and a document map are constructed and clusters are distinguished in both of them. The validity of the document clustering is verified by a manual analysis of a sample of the editorials. This analysis confirms the homogeneity of the clusters obtained by mapping and augments the latter with further detail. As a result, the analysis provides reliable information on the distribution of the editorials over topics, and on differences between the journals. The most striking difference is that Nature devotes more attention to internal science policy issues and Science more to the political influence of scientists.

  11. Usability of Security Management:Defining the Permissions of Guests

    Science.gov (United States)

    Johnson, Matthew; Stajano, Frank

    Within the scenario of a Smart Home, we discuss the issues involved in allowing limited interaction with the environment for unidentified principals, or guests. The challenges include identifying and authenticating guests on one hand and delegating authorization to them on the other. While the technical mechanisms for doing so in generic distributed systems have been around for decades, existing solutions are in general not applicable to the smart home because they are too complex to manage. We focus on providing both security and usability; we therefore seek simple and easy to understand approaches that can be used by a normal computer-illiterate home owner, not just by a trained system administrator. This position paper describes ongoing research and does not claim to have all the answers.

    Host-guest chemistry involves the complimentary binding between two molecules. Host molecules have been synthesized to bind negative, positive, and neutral molecules such as proteins and enzymes, and have been used as optical sensors, electrochemical sensors, supramolecular catalysts, and in the pharmaceutical industry as anti-cancer agents.1 The field of nanoscience has exploited guest-host interactions to create optical sensors with colloidal gold and Dip-Pen nanolithography technologies. Gold nanoparticles, have been functionalized with DNA, and have been developed as a selective colorimetric detection system, that upon binding turns the solution from a red to blue in color.2 Cyclotriveratrylene (CTV) 1 is a common supramolecular scaffold that has been previously employed in guest-host chemistry, and the construction of CTV involves the cyclic trimerization of veratryl alcohol via the veratryl cation.3 Due to the rigid bowl shaped structure of CTV, CTV has been shown to act as a host molecule for fullerene-C60.4 Lectin binding receptor proteins are a specific class of proteins found in bacteria, viruses, plants, and animals that can bind to complimentary carbohydrates. It is these lectins that are believed to be responsible for cell-cell interactions and the formation of biofilms in pathenogenic bacteria.5 P. aeruginosa is a pathenogenic bacterium, shown to have a high resistance to many antibiotics, which can form biofilms in human lung tissue, causing respiratory tract infections in patients with compromised immune systems. 5 I will exploit guest-host interactions to create synthetic supramolecular and carbohydrate receptor molecules to that will be of use as biological sensing devices via self-assembled monolayers on solid surfaces and nanoparticle technologies. *Please refer to dissertation for references/footnotes.

    The Journal of Magnetic Resonance has played a prominent role in encouraging synergies between physical insights and biophysical applications. In this Virtual Special Issue (VSI), JMR's associate editor Dr. Robert (Rob) Tycko highlights the state-of-the-art in this area, by presenting a compilation of JMR articles published over recent years that demonstrate the value of indirect detection methods in biosolids NMR. This is a topic that Rob knows only too well, having been one of its founders and main expositors. This thematic VSI also gives a perfect "excuse" for thanking Rob for the seven years that he has served as our card-carrying solids NMR associate editor. His work for the Journal was, like all other NMR endeavors in which Rob has embarked, characterized by utmost excellence. Over the years he contributed numerous ideas and initiatives, while providing editorial judgment in the handling of over 320 individual papers. For all this we in the NMR community wish to extend Rob our sincere thanks; to offer him our best wishes for a continued successful career and happiness in all walks of life, and to express our hope that we can keep on counting on his wisdom and advice as member of our Editorial Board. I would also like to use this opportunity to extend a warm welcome to Chad Rienstra, who will be replacing Rob in his role of associate editor.

    Particulate polymeric microfibers with incorporated europium(III)oxide (Eu2O3) nanoparticles were introduced as a magneto-photoluminescent multifunctional material fabricated via reversal nanoimprint lithography. To specifically address the volume properties of these guest-host particles, the guest, Eu2O3, was milled down to an average particle size of 350 nm in diameter and mixed with the host-polymer, AMONIL®, before in situ hardening in the imprint stamp. The variation of the fabrication process parameters, i.e. delay time, spin coating speed, as well as the concentration of Eu2O3 nanoparticles was proven to have a significant impact on both the structure quality and the stamp release of the microfibers with respect to the formation of a thinner residual layer. Structural characterization performed by SEM revealed optimum fabrication process parameters for a homogeneous spatial distribution of Eu2O3 nanoparticles within the microfibers while simultaneously avoiding the formation of undesired agglomerates. The magneto-photoluminescent properties of Eu2O3 nanoparticles, i.e. a red emission at 613 nm and a paramagnetic response, were found to be superimposed to the optic and the diamagnetic behaviors of AMONIL®. The results imply that guest-host interdependence of these properties can be excluded and that the suggested technique enables for specific tailoring of particulate multifunctional materials with focus on their volume properties.

Editorials in Nature and Science are such non-specialist documents, reflecting the views of the two most read scientific journals on science, technology and policy issues. We use the VOSviewer mapping software to chart the topics of these editorials. ...

  1. Synthesis and Guest Recognition of Switchable Pt-Salphen Based Molecular Tweezers

    Directory of Open Access Journals (Sweden)

    2018-04-01

    Full Text Available Molecular tweezers are artificial receptors that have an open cavity generated by two recognition units pre-organized by a spacer. Switchable molecular tweezers, using a stimuli-responsive spacer, are particularly appealing as prototypes of the molecular machines that combine mechanical motion and allosteric recognition properties. In this present study, the synthesis of switchable molecular tweezers composed of a central terpyridine unit substituted in 4,4″ positions by two Pt(II-salphen complexes is reported. The terpyridine ligand can be reversibly converted upon Zn(II coordination from a free ‘U’-shaped closed form to a coordinated ‘W’ open form. This new substitution pattern enables a reverse control of the mechanical motion compared to the previously reported 6,6″ substituted terpyridine-based tweezers. Guest binding studies with aromatic guests showed an intercalation of coronene in the cavity created by the Pt-salphen moieties in the closed conformation. The formation of 1:1 host-guest complex was investigated by a combination of NMR studies and DFT calculations.

  2. Hotel guest's $14.5 million jury verdict set aside on appeal.

    1999-08-20

    A Missouri Court of Appeals judge reversed a $14.5 million judgement against [name removed] Inc., which had been held liable for the beating and sexual assault of a guest in its hotel. The guest, identified as [name removed], had requested an upgrade to a concierge room, to increase her safety, but the hotel did not fill her request. When [name removed] opened her hotel room door the next morning, an assailant attacked, beat and raped her. The assailant escaped hotel security, but was later apprehended. The initial case against [name removed] and the assailant resulted in a $22.5 million judgement for [name removed] Both parties appealed. [Name removed] prevailed in its argument that the initial trial judge misinstructed the jury, and that [name removed] was unable to show clear and convincing evidence that the hotel's willful or conscious disregard for guest safety caused the situation. However, the court ruled against [name removed] on the basis of [name removed]'s fear-of-AIDS claim, because of her exposure to the virus.

    This study examines two newspapers' editorial coverage of issues related to the Healthy People 2010 focus areas and compares the two newspapers. A qualitative study. Two Los Angeles, California, newspapers. The masthead editorials of the Los Angeles Times and La Opinión in the year following the release of Healthy People 2010. A structured data abstraction instrument was used for descriptive coding. Correspondence to 1 of the 28 Healthy People 2010 focus areas determined whether domestic editorials were about health. An ethnographic content analysis. There were 1075 editorials from the Los Angeles Times and 361 from La Opinión; 17% were focused on domestic health issues. Three Healthy People 2010 focus areas dominated: Environmental Health, Injury and Violence Prevention, and Access to Quality Health Services. Ten focus areas did not receive a single mention in the Los Angeles Times, and 19 focus areas lacked editorials in La Opinión. Editorial writers regularly tackled issues related to a Healthy People 2010 focus area. Public health practitioners can meet with their local newspaper editorial board and discuss the nation's health objectives as manifested by Healthy People 2020 and the National Prevention Strategy, thereby promoting policies that support individual and population health.

    2017-06-13

    The interactions between a host, water-soluble corona[n]arene (S6-CAP), and a series of guests, bisquaternary ammonium derivatives (CnDAs), in water, were investigated. The host and guest can form 1:1 host-guest complex. Their binding constants decrease as the alkyl length of CnDAs increases, which can be tunable ranging from 10 3 to 10 6 M -1 . The binding processes are mainly entropy-driven, while the enthalpy changes also play an important role in enhancing the host-guest interactions. In addition, a supra-amphiphile was fabricated with S6-CAP and a normal surfactant bearing bisquaternary ammonium (C4R). The S6-CAP·C4R complex forms micellar aggregates in water, and the system possesses better assembling activity and dilution stability than its building block C4R. This study enriches the families of supra-amphiphiles with a new architecture, and employing such a supra-amphiphile in biofunctional materials is highly anticipated.

    Full Text Available Applied linguists paying scholarly attention to newspaper genres have often argued that findings emerging from such studies would be of pedagogical significance because most of the newspaper genres share certain conventional features with school genres. Similarly, this study explored lexical cohesion in newspaper editorials, and it is understood that the findings could help learners in handling persuasive writings. The study sought to identify the dominant sources of lexical cohesion in the editorials, and also to examine how lexical cohesion is utilized to achieve coherence in the editorials. Drawing on Systemic Functional Linguistics (SFL, the study applied Eggins’ (2004 model of lexical cohesion and analyzed 30 editorial texts of 20, 354 words drawn from three major Nigerian newspapers: The Guardian, The Nation, and Vanguard. The analysis revealed 2, 685 ties across 849 sentences. The data demonstrated that the major types of lexical cohesion in the editorials include: repetition (49.5%, expectancy relations (15. 8%, class/sub-class (11%, and synonymy (10.8%. It was further revealed that lexical cohesion devices, which formed into chains (586 and isolated ties (837, were utilized in building coherence in the editorial texts. It was finally shown how findings of the study could be beneficial in ESP, EAP, and EGP learning, especially in persuasive writings.

    2015-07-01

    With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

  13. Perception of service quality in agrotourism accommodations: Impact on guest loyalty and re-visit intentions

    Directory of Open Access Journals (Sweden)

    Chryssoula Chatzigeorgiou

    2017-03-01

    Full Text Available This study presents the development of a conceptual model that demonstrates the dynamic nature of the relationship between service quality and guest satisfaction in the agrotourism accommodation sector, based on theories derived from social psychology and previous research in the marketing, management, and services literature. The model was tested using sample data from guests of four different agrotourism firms, and was modified because of empirical results. The final model improves understanding of the relationship between service quality and guest satisfaction because these constructs were examined from the process perspective of an agrotourism accommodation experience; it portrays service quality and satisfaction in the context of a complete system.

    This year Nuclear Fusion celebrates its fiftieth anniversary. This has been marked by the January special edition, containing papers presented at the plenary and celebratory evening session of the 22nd Fusion Energy Conference at Geneva. These papers underline the enormous progress that has been made in the last 50 years both in experiment and theory. Whilst the technical challenges that we face are still formidable, they are largely concerned with engineering a fusion reactor rather than fundamental plasma physics. In my editorial of a year ago, I remarked on the price of oil and the incentive that it gives to develop nuclear fusion into a viable energy source. This last year, attention has shifted somewhat from the markets to the environment and the Copenhagen climate summit in particular. The timescale for action on the environment is much shorter than we can possibly match and so we can only play our part towards developing long term solutions. Our responsibility is to present a programme that has the clear goal in developing a sustainable source of energy and, as the next step, make an unambiguous success of ITER. The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. The journal depends entirely on its authors and referees and so I would like to thank them all for their work in 2009 and look forward to a continuing, successful collaboration in 2010. Refereeing The Nuclear Fusion Editorial Office understands how much effort is required of our referees. The Editorial Board decided that an expression of thanks to our most loyal referees is appropriate and so, since January 2005, we have been offering the top ten most active referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. This year, seven of the top referees have reviewed four or more manuscripts in the period November 2008 to

  17. Circularly Polarized Luminescence from Inorganic Materials: Encapsulating Guest Lanthanide Oxides in Chiral Silica Hosts.

    Recently, circularly polarized luminescence (CPL)-active systems have become a very hot and interesting subject in chirality- and optics-related areas. The CPL-active systems are usually available by two approaches: covalently combining a luminescent centre to chiral motif or associating the guest of luminescent probe to a chiral host. However, all the chiral components in CPL materials were organic, although the luminescent components were alternatively organics or inorganics. Herein, the first totally inorganic CPL-active system by "luminescent guest-chiral host" strategy is proposed. Luminescent sub-10 nm lanthanide oxides (Eu 2 O 3 or Tb 2 O 3 ) nanoparticles (guests) were encapsulated into chiral non-helical SiO 2 nanofibres (host) through calcination of chiral SiO 2 hybrid nanofibres, trapping Eu 3+ (or Tb 3+ ). These lanthanide oxides display circular dichroism (CD) optical activity in the ultraviolet wavelength and CPL signals around at 615 nm for Eu 3+ and 545 nm for Tb 3+ . This work has implications for inorganic-based CPL-active systems by incorporation of various luminescent guests within chiral inorganic hosts. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The Internet has dramatically expanded citizens' access to and ability to engage with political information. On many websites, any user can contribute and edit "crowd-sourced" information about important political figures. One of the most prominent examples of crowd-sourced information on the Internet is Wikipedia, a free and open encyclopedia created and edited entirely by users, and one of the world's most accessed websites. While previous studies of crowd-sourced information platforms have found them to be accurate, few have considered biases in what kinds of information are included. We report the results of four randomized field experiments that sought to explore what biases exist in the political articles of this collaborative website. By randomly assigning factually true but either positive or negative and cited or uncited information to the Wikipedia pages of U.S. senators, we uncover substantial evidence of an editorial bias toward positivity on Wikipedia: Negative facts are 36% more likely to be removed by Wikipedia editors than positive facts within 12 hours and 29% more likely within 3 days. Although citations substantially increase an edit's survival time, the editorial bias toward positivity is not eliminated by inclusion of a citation. We replicate this study on the Wikipedia pages of deceased as well as recently retired but living senators and find no evidence of an editorial bias in either. Our results demonstrate that crowd-sourced information is subject to an editorial bias that favors the politically active.

    Science.gov (United States)

    Li, Shenhui; Li, Jing; Tang, Jing; Deng, Feng

    Solid-state NMR was utilized to explore the host-guest interaction between adsorbate and adsorbent at atomic level to understand the separation mechanism of styrene (St) and ethylbenzene (EB) in MIL-53(Al). 13 C- 27 Al double-resonance NMR experiments revealed that the host-guest interaction between St and MIL-53 was much stronger than that of EB adsorption. In addition, 13 C DIPSHIFT experiments suggested that the adsorbed St was less mobile than EB confined inside the MIL-53 pore. Furthermore, the host-guest interaction model between St, EB and MIL-53 was established on the basis of the spatial proximities information extracted from 2D 1 H- 1 H homo-nuclear correlation NMR experiments. According to the experimental observation from solid-state NMR, it was found that the presence of π-π interaction between St and MIL-53 resulted in the stronger host-guest interaction and less mobility of St. This work provides direct experimental evidence for understanding the separation mechanism of St and EB using MIL-53 as an adsorbent.

In this paper we established as an objective to examine in detail the importance given by the consumers to the components of guest service quality and their perceived performance, based on the three pillars of service quality: the material base (equipments, staff training and staff behavior. The emphasis is on the investigation regarding staff training and behaviour, taking into account the multiple attributes SERVQUAL scale. On the basis of this work lies a survey done in March-April 2010 on the population of Oradea, on a sample of 1060 people. Results confirm the importance granted to staff in ensuring quality of tourism services and their perceived relatively weak performance.

    Through their editorializing practices, leading international science journals such as Nature and Science interpret the changing roles of science in society and exert considerable influence on scientific priorities and practices. Here we examine nearly 500 editorials published in these two journals between 1966 and 2016 that deal with climate change, thereby constructing a lens through which to view the changing engagement of science and scientists with the issue. A systematic longitudinal frame analysis reveals broad similarities between Nature and Science in the waxing and waning of editorializing attention given to the topic, but, although both journals have diversified how they frame the challenges of climate change, they have done so in different ways. We attribute these differences to three influences: the different political and epistemic cultures into which they publish; their different institutional histories; and their different editors and editorial authorship practices.

    Signal transducer and activator of transcription factor 3 (STAT-3) is known to be overexpressed in cancer stem cells. Poor solubility and variable drug absorption are linked to low bioavailability and decreased efficacy. Many of the drugs regulating STAT-3 expression lack aqueous solubility; hence hindering efficient bioavailability. A theranostics nanoplatform based on luminescent carbon particles decorated with cucurbit[6]uril is introduced for enhancing the solubility of niclosamide, a STAT-3 inhibitor. The host–guest chemistry between cucurbit[6]uril and niclosamide makes the delivery of the hydrophobic drug feasible while carbon nanoparticles enhance cellular internalization. Extensive physicochemical characterizations confirm successful synthesis. Subsequently, the host–guest chemistry of niclosamide and cucurbit[6]uril is studied experimentally and computationally. In vitro assessments in human breast cancer cells indicate approximately twofold enhancement in IC50 of drug. Fourier transform infrared and fluorescence imaging demonstrate efficient cellular internalization. Furthermore, the catalytic biodegradation of the nanoplatforms occur upon exposure to human myeloperoxidase in short time. In vivo studies on athymic mice with MCF-7 xenograft indicate the size of tumor in the treatment group is half of the controls after 40 d. Immunohistochemistry corroborates the downregulation of STAT-3 phosphorylation. Overall, the host–guest chemistry on nanocarbon acts as a novel arsenal for STAT-3 inhibition. PMID:27545321

    I am very pleased to be assuming the Editorship of Classical and Quantum Gravity for the next five years. I hope to continue the successful policies that have made this journal well known for its openness to new developments in the field, for the efficiency of its editorial process, and for the quality and importance of its articles. Classical and Quantum Gravity has truly blossomed under the guidance of its previous Editors-in-Chief, Malcolm MacCallum, Kellogg Stelle, Gary Gibbons and Hermann Nicolai. During the past 12 months, a total of 847 manuscripts have been submitted, representing an increase of nearly 50% over the past four years alone. Beginning in 2000, the frequency of publication was increased from 12 to 24 issues per year. The rate of full-text downloads is now 7200 per month, nearly a three-fold increase over four years. For regular manuscripts, the average time between receipt and first decision now stands at only 59 days, the receipt-to-acceptance time is now only 72 days, and the receipt-to-online publication time is only 116 days. The corresponding times for letters are 36 days, 44 days and 62 days, respectively. Much of the improvement in refereeing and publication times can be directly attributed to the state-of-the art Web-based refereeing system, maintained by the able administration of the IOP editorial team, consisting of Andrew Wray, Joe Tennant, Joanne Rowse and Susannah Bruce. Both the growth in journal size and the decrease in publication times have been accomplished without any decrease in quality. As one objective measure of this, the 'impact factor' index of Classical and Quantum Gravity has risen steadily over the past four years. Even more significantly, Classical and Quantum Gravity has undergone major intellectual growth since its founding. In 1984, modern string theory was in the process of being born, the subject of 'loop quantum gravity' did not exist at all, 'new inflation' truly was 'new', and the possibility of observing

    Membership on a professional medical society or journal editorial board is a marker of influence and prestige for those in academic medicine. This study presents the first comprehensive quantification of women on these boards and the implications for women in medicine. The numbers of women and men on professional society and journal editorial boards across 28 specialties (March 2004) were counted. The number of women holding multiple roles on these boards and the number of women holding top leadership positions on these boards were counted, and these proportions were compared. Three-thousand-four-hundred-seventy-three individuals on 39 professional medical society boards and 54 journal editorial boards were included. Eighty-three percent (2,884) of board members were male. Men occupied > 80% of top leadership positions on these boards. Thirty-five of the 589 women in the study held multiple roles. Anesthesiology (p women on boards in comparison to the total women in the specialty. Internal medicine, plastic surgery, cardiology and general surgery had nearly equivalent proportions; in otolaryngology and family medicine, female board members slightly exceeded the proportion of women in the field. Women's representation on society and editorial boards does not always reflect their presence in medical specialties, and it is critically lacking in certain specialties. Efforts should be made to attain parity of women leaders on these boards. Further efforts should be made to eliminate barriers to women's leadership in medicine.

  9. Tweens on the Internet - communication in virtual guest books

    Full Text Available  Today digital communication is a natural part of young people’s social life. It has increased drastically during the last few years, and there are still a lot of questions about what this means, and how this new media affects communication. This study focuses on young people of 11-13, i.e.the age between children and teenagers, also called tweens. In a large study, the overall aim is to see what communication in the Internet community LunarStorm means to them in their social life. This particular paper reports on the content of the asynchronous communication in the participants’ digital guest books, which is one of the main channels for communication between the participants. A group of 15 tweens from a small village in Sweden were studied when communicating in Sweden’s largest Internet community, LunarStorm. The research method used was what is usually described as cyber ethnography. The contributions in the participants’ digital guest books are not written by the guest book owners themselves, which means that the focus is on the collective aspects of this communication, and not from a specific children’s point of view. Qualitative analyses were made of the content of 947 contributions in the participants’ guest books in order to make a statistical analysis. Most of the participants’ communication was between friends in the same geographical neighbourhood concerning how things are going, what to do, when to meet and similar things. The contributions were divided into three categories: (1 Social chat (2 Chain letters, and (3 Messages incomprehensible to outsiders. The information-category was divided into three sub-categories depending on the emotions expressed. 44% of the total messages were considered as emotionally neutral information, 39% as kind or encouraging, and also with an aim to sort things out, and 6% of the total messages contained insults and elements of anger.

    2015-12-07

    The design of synthetic, monovalent host-guest molecular recognition pairs is still challenging and of particular interest to inquire into the limits of the affinity that can be achieved with designed systems. In this regard, cucurbit[7]uril (CB[7]), an important member of the host family cucurbit[n]uril (CB[n], n = 5-8, 10, 14), has attracted much attention because of its ability to form ultra-stable complexes with multiple guests. The strong hydrophobic effect between the host cavity and guests, ion-dipole and dipole-dipole interactions of guests with CB portals helps in cooperative and multiple noncovalent interactions that are essential for realizing such strong complexations. These highly selective, strong yet dynamic interactions can be exploited in many applications including affinity chromatography, biomolecule immobilization, protein isolation, biological catalysis, and sensor technologies. In this review, we summarize the progress in the development of high affinity guests for CB[7], factors affecting the stability of complexes, theoretical insights, and the utility of these high affinity pairs in different challenging applications.

    Host-guest complexation with various hydrophobic drugs has been used to enhance the solubility, permeability, and stability of guest drugs. Physical changes in hydrophobic drugs by complexation have been related to corresponding increases in the bioavailability of these drugs. Carbohydrates, including various derivatives of cyclodextrins, cyclosophoraoses, and some linear oligosaccharides, are generally used as host complexation agents in drug delivery systems. Many antibiotics with low bioavailability have some limitations to their clinical use due to their intrinsically poor aqueous solubility. Bioavailability enhancement is therefore an important step to achieve the desired concentration of antibiotics in the treatment of bacterial infections. Antibiotics encapsulated in a complexation-based drug delivery system will display improved antibacterial activity making it possible to reduce dosages and overcome the serious global problem of antibiotic resistance. Here, we review the present research trends in carbohydrate-based host-guest complexation of various hydrophobic antibiotics as an efficient delivery system to improve solubility, permeability, stability, and controlled release.

    Clathrate hydrates, or gas hydrates, are stabilized by van der Waals interaction between a guest molecule and a host framework. Because of their property, they are a potential resource in the exploitation of natural gas hydrates, as a material for the sequestration of carbon dioxide (CO{sub 2}), as a means of storage and transportation of natural gas, as well as hydrogen storage. Clathrate hydrate research can be divided into two categories that emphasize either macroscopic or microscopic approaches. However, these two approaches need to be closely linked for a better understanding of the structures and processes involving both natural phenomena and hydrates for industrial processes. Details on the molecular scale that concern the less usual properties of clathrate hydrates remain unknown. This paper presented the results of a study that reported on the existence of a critical guest concentration (CGC) and established the complete tuning pattern that occurred in the binary hydrates, including water-soluble hydrate formers (promoters) and water-insoluble guests. The paper presented the experimental procedures, including formation of the methane (CH{sub 4}) and tetrahydrofuran (THF) binary hydrate; a schematic diagram of the experimental apparatus; and formation of the CH{sub 4} and t-BuNH{sub 2} binary hydrate. Nuclear magnetic resonance (NMR) spectroscopic measurements and thermodynamic measurements were also presented. It was concluded that the CGC value appeared to primarily depend on the chemical nature of a liquid guest component participating in the binary hydrate formation. 10 refs., 2 tabs., 9 figs.

    Full Text Available A notion, according to which editorials have a bigger communication influence than advertisements, is very common and quite popular in public relations. The said notion is so prevalent (among both public relations and marketing communications experts that it has led to the concept of perceived influence multipliers that point to a stronger editorial influence in comparison to advertising influence (2.5 to 8 times stronger. Based on the described assumption, the aim of this paper was to further explore how the target audience perceives editorial and advertising content. The research problem was to compare the effects of both types of content on behavior and behavioral intent (through four media – Internet, radio, newspapers and television. Respondents were divided into two groups – current users of the service that was in focus (for influence on behavior and potential users (for influence on behavioral intent. Even though current users said that editorials had a bigger influence on their behavior, this difference was not significant. On the other hand, potential users stated that the advertising content shaped their behavioral intent more than did editorials. These results once again show the assumption, according to which editorials have a stronger communication influence than advertisements, to be highly questionable.

    Materials capable of sensing volatile guests at room temperature by an easily monitored set of outputs are of great appeal for development as chemical sensors of small volatile organics and toxic gases. Herein the dinuclear iron(II) complex, [Fe II 2 (L) 2 (CH 3 CN) 4 ](BF 4 ) 4 ⋅2 CH 3 CN (1) [L=4-(4-methylphenyl)-3-(3-pyridazinyl)-5-pyridyl-4H-1,2,4-triazole], is shown to undergo reversible single-crystal-to-single-crystal (SCSC) transformations upon exposure to vapors of different guests: 1 (MeCN)⇌2 (EtOH)→3 (H 2 O)⇌1 (MeCN). Whilst 1 and 2 remain dimetallic, SCSC to 3 involves conversion to a 1D polymeric chain (due to a change in L bridging mode), which, remarkably, can undergo SCSC de-polymerization, reforming dimetallic 1. Additionally, SC-XRD studies of two ordered transient forms, 1TF3 and 2TF3, confirm that guest exchange occurs by diffusion of the new guests into the non-porous lattices as the old guests leave. These reversible SCSC events also induce color and magnetic responses. Indeed dark red 1 is spin crossover active (T 1/2 ↓ 356 K; T 1/2 ↑ 369 K), whilst orange 2 and yellow 3 remain high spin. © 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The main objective of this special issue is to collect and disseminate publications that highlight recent advances and breakthroughs in the area of renewable energy resources. The use of these resources for production of electricity is increasing rapidly worldwide. As of 2015, a majority of countries have set renewable electricity targets in the 10%-40% range to be achieved by 2020-2030, with a few notable exceptions aiming for 100% generation by renewables. We are experiencing a truly unprecedented transition away from fossil fuels, driven by environmental, energy security, and socio-economic factors.Electric machines can be found in a wide range of renewable energy applications, such as wind turbines, hydropower and hydrokinetic systems, flywheel energy storage devices, and low-power energy harvesting systems. Hence, the design of reliable, efficient, cost-effective, and controllable electric machines is crucial in enabling even higher penetrations of renewable energy systems in the smart grid of the future. In addition, power electronic converter design and control is critical, as they provide essential controllability, flexibility, grid interface, and integration functions.

Qualitative study of hotel management and quantitative content analysis of media coverage of smoke-free hotels. Hotels and media based in the United States. Eleven representatives of 5 independent and 4 chain hotels. Other data included 265 news items about smoke-free hotels. We conducted 30-minute semi-structured interviews with hotel representatives and analyzed the data using qualitative content analysis. We also searched 3 online news databases for news items about hotels in our study, and collaboratively coded retrieved items; we analyzed the content and slant of news items. Business considerations, including guest requests, competitor action, and cost savings, were the primary motivations for implementing 100% smoke-free guest-room policies. Health concerns played a minimal role. Hotels received positive feedback from customers and employees. Media coverage was favorable, emphasizing positive aspects of going smoke-free; the overall slant of news items was positive or neutral. However, few hotels marketed the change. Since hotel customers and employees are likely to experience long periods of smoke exposure and smoke-free hotels appear to be so well received, it may be timely to pursue policies making all hotels smoke-free.

    Guest-host polymer-dispersed liquid crystal (GHPDLC) films were prepared using a nematic liquid crystal, photo-curable polymer and dichroic dye (anthraquinone blue) by polymerization-induced phase separation (PIPS) technique. Non-ionic dichroic dye (1%, 2% and 4% wt./wt. ratio) was taken as guest in PDLC host. Polarizing microscopy shows that in the absence of electric field, liquid crystal (LC) droplets in polymer matrix mainly exhibit bipolar configuration, however, relatively at higher field, maltese-type crosses were observed. Our results show that approx1% dye-doped PDLC film shows better transmission and faster response times over pure polymer-dispersed nematic liquid crystal (PDNLC) and higher concentrated (2% and 4%) GHPDLC films.

    Graphical abstract: - Highlights: • Different conformation of β-CD derivatives. • Enthalpy gain. • High binding ability. - Abstract: The molecular binding behaviors of two β-cyclodextrin (β-CD) derivatives bearing 1,2,3-triazole moieties, i.e. mono-6-deoxy-6-{4-(8-oxymethylquinolino)[1,2,3]triazolyl}-β-CD (1) and mono-6-deoxy-6-{4-(8-oxymethylnaphthol)[1,2,3]triazolyl}-β-CD (3), and their analogs without 1,2,3-triazole moieties, i.e. mono-6-deoxy-6-(8-oxymethylquinolino)-β-CD (2) and mono-6-deoxy-6-(8-oxymethylnaphthol)-β-CD (4) toward spherical guests (±)-borneol and (±)-camphor were investigated to elucidate how substituent moiety of host affects the binding abilities by 2D NMR as well as microcalorimetric titrations in aqueous phosphate buffer solution (pH 7.20) at 298.15 K. The binding modes of host–guest interactions obtained from 2D NMR displayed that host CDs without triazole moieties gave better induce-fit efficiency between hosts and guests, leading to stronger binding abilities. Thermodynamically, the inclusion complexation was driven by enthalpy with the stoichiometry of 1:1. Another factor contributed to the enhanced binding abilities was the enthalpy gain with the smaller entropy loss.

  15. Dielectric relaxation of guest molecules in a clathrate structure of syndiotactic polystyrene.

    2012-12-13

    Structure and dynamics of semicrystalline polymer films composed of syndiotactic polystyrene (sPS) and 2-butanone were examined through X-ray diffraction, polarized FTIR, and dielectric relaxation measurements. The X-ray and FTIR measurements revealed its crystal structure to be δ-clathrate containing 2-butanone molecules inside. The carbonyl group of 2-butanone in the crystal was found to orient preferentially parallel to the ac plane of the crystal through the polarized ATR FTIR measurements. Dielectric measurements were also conducted on these film samples to see only the relaxation dynamics of 2-butanone thanks to the high dielectric intensity of 2-butanone compared to sPS. Two relaxation modes denoted by slow and fast modes appeared. The former was assigned to the motion of 2-butanone molecules entrapped in the cavities of the crystalline (δ-form) and the latter to those in the amorphous region. We focused on the slow mode in order to elucidate the specific dynamics of the guest molecule confined in the crystalline region. The relaxation time of the slow mode was about 4 orders of magnitude longer than that of liquid 2-butanone. This suggests that the dynamics of guest molecules is highly restricted due to the high barrier to conformational and/or orientational change of the guest molecule in the cavity of δ-crystal. Furthermore, the dielectric intensity Δε of the slow mode was much smaller than the one calculated from that of bulk liquid 2-butanone and the guest concentration in the crystalline region (the intensity was only 10% of the estimated value from the bulk liquid data). This result also indicates that the free rotational motion of 2-butanone molecules is restricted inside the crystal. This will be consistently related to the weak uniplanar orientation of the carbonyl group of 2-butanone parallel to the ac plane revealed by the X-ray and polarized ATR FTIR measurements.

    This issue marks the end of an era for The Astrophysical Journal and for astronomical publishing. Helmut Abt is retiring as Editor-in-Chief after serving for 28 years, a period that saw enormous growth in the Journal and its transformation to the forefront of electronic scientific publishing. In February the ApJ office celebrated the receipt of manuscript number 40,000 under Helmut's tenure, a milestone that testifies to his impact on all of our careers. Although the names at the top of the masthead are changing, the rest of the ApJ team remains nearly unchanged, so the editorial transition should be barely noticeable. Much of the editorial work of the Journal will continue to be performed by our capable staff of Scientific Editors. I am also very fortunate to inherit Helmut's outstanding support staff in Tucson, ably headed by Janice Sexton. Our publications staff in Chicago, led by Julie Steffen, and our electronic publications staff, led by Evan Owens, are unmatched in their dedication and energy, and I have already begun working with them on further improvements to the Journal. And Helmut Abt will continue to serve the Journal over the coming months, overseeing the manuscripts that are still under review and editing the special centennial issue that will appear at the end of this year. In the coming months we will introduce several new features, most of them initiated under Helmut Abt's leadership. These will include an upgraded ApJ homepage, web tools for authors and referees, updated documentation and author instructions, and an attractive new version of the on-line journal itself. Over the longer term we are developing plans for streamlining the publication timescale and for expanding our capabilities for publishing and archiving electronic data. However my overriding priority, always, will be to uphold the Journal's reputation for scientific accuracy, impact, and integrity.

    Two years have now passed since I took over from Prof. Dan van Wyk as Editor in Chief of IEEE Transactions on Power Electronics. In this period major changes have been implemented as modern journal publications are moving more to all digital publishing. When I took over we introduced Manuscript...... Central as a tool for handling the paper flow and the last two years have shown this was really a right move. It is powerful both for authors, reviewers, associate editors, Editor in Chief and the administrator. Continuously we can track all papers, identify old papers in the process, see statistics......, identify critical delays, track old information etc. Also the Editorial Office is now receiving the final paper all digital without ordinary mail submission which is really making life easier.

  7. Editorial highlighting and highly cited papers

    Science.gov (United States)

    Antonoyiannakis, Manolis

    Editorial highlighting-the process whereby journal editors select, at the time of publication, a small subset of papers that are ostensibly of higher quality, importance or interest-is by now a widespread practice among major scientific journal publishers. Depending on the venue, and the extent to which editorial resources are invested in the process, highlighted papers appear as News & Views, Research Highlights, Perspectives, Editors' Choice, IOP Select, Editors' Summary, Spotlight on Optics, Editors' Picks, Viewpoints, Synopses, Editors' Suggestions, etc. Here, we look at the relation between highlighted papers and highly influential papers, which we define at two levels: having received enough citations to be among the (i) top few percent of their journal, and (ii) top 1% of all physics papers. Using multiple linear regression and multilevel regression modeling we examine the parameters associated with highly influential papers. We briefly comment on cause and effect relationships between citedness and highlighting of papers.

    A dozen of homoditopic cations, possessing different spacer lengths and rigidities, as well as sizes, shapes, and charges of terminal groups, were synthesized as candidate gemini guests for the complexation of p-sulfonatocalix[4]arenes (SC4A). The 12 gemini guests are divided into five species according to the different terminal groups: imidazolium (G1-G3), pyridinium (G4-G6), quinolinium (G7), viologen (G8-G11), and 1,4-diazabicyclo[2.2.2]octane (DBO, G12). Their binding structures and stoichiometries with SC4A were examined by NMR spectroscopy, which is helpful to construct diverse highly ordered assemblies. The obtained results show that the length of the linkers, as well as the charge numbers on the end groups have a pronounced effect on the binding stoichiometry, whereas the size and shape of the terminal groups have no significant influence. Furthermore, both the stability constants and thermodynamic parameters of SC4A with the terminal subunits were determined by the isothermal titration calorimetry experiments, which are valuable to understand the binding behavior, giving quantitatively deep insight.

I have watched this journal grow from an idea to a sustainable, reputable journal with readers and contributors from all over the world. It has grown from a small editorial group to a collection of peer reviewers, Evidence Summary writers, copyeditors, etc., that is eighty-four strong (and counting. I have wavered between wondering whether promoting evidence based librarianship is akin to flogging a dead horse to feeling secure in knowing that we are making a difference. Being involved with this journal has made me look at what I do in a different light and I now approach decisions and change with what I refer to as “structured flexibility”. Following the EBL framework is the structured part, and when it works, it works well. But we all know that there is not always an answer in the literature nor is there a guarantee that implemented evidence based change will work similarly in different environments. That’s where the flexibility comes in.Three years as Editor-in-Chief has been a challenging, enjoyable, time-consuming, and fascinating learning experience. It has provided me with numerous opportunities in terms of speaking engagements, workshop offerings, and valuable discussion and discourse. It has also provided me with research and project ideas that I have had to place on the back burner until a time when I have enough hours in the day. Recognizing that adding additional hours to the day is, well, impossible, I have decided to stepdown from my editorial role to pursue other activities. This was a bittersweet decision, but a necessary one. I am pleased to announce that Denise Koufogiannakis will be taking on the role of Editor-in-Chief for the next term.

  12. Host-guest chemistry of dendrimer-drug complexes: 7. Formation of stable inclusions between acetylated dendrimers and drugs bearing multiple charges.

    Drug molecules bearing multiple charges usually form precipitates with cationic dendrimers, which presents a challenge during the preparation of dendrimer inclusions for these drugs. In the present study, fully acetylated polyamidoamine (PAMAM) dendrimers were proposed as stable vehicles for drug molecules bearing two negative charges such as Congo red and indocyanine green. NMR techniques including (1)H NMR and (1)H-(1)H NOESY were used to characterize the host-guest chemistry of acetylated dendrimer and these guest molecules. The cationic PAMAM dendrimer was found to form a precipitate with Congo red and indocyanine green, but the acetylated one avoided the formation of cross-linking structures in aqueous solutions. NOESY studies revealed the encapsulation of Congo red and indocyanine green within the interior cavities of PAMAM dendrimers at mild acidic conditions and acetylated dendrimers show much stronger ability to encapsulate the guest molecules than cationic ones. Also, UV-vis-NIR studies suggest that acetylated dendrimers significantly improve the photostability of indocyanine green and prevent the formation of indocyanine green J-aggregates in aqueous solutions. The present study provides a new insight into dendrimer-based host-guest systems, especially for those guest molecules bearing multiple charges. © 2012 American Chemical Society

    Complexation between a triptycene-derived macrotricyclic polyether containing two dibenzo-[30]-crown-10 cavities and different functionalized paraquat derivatives, diquat, and a 2,7-diazapyrenium salt in both solution and solid state was investigated in detail. It was found that depending on the guests with different terminal functional groups and structures, the macrotricyclic polyether could form 1:1 or 1:2 complexes with the guests in different complexation modes in solution and also in the solid state. Especially, the conformation of the macrotricyclic polyether was efficiently adjusted by the encapsulated guests, which was to some extent similar to substrate-induced fit of enzymes. Moreover, the binding and releasing of the guests in the complexes could be controlled by potassium ions.

    2017-09-01

    Decades after the birth of supramolecular chemistry, there are many techniques to measure noncovalent interactions, such as hydrogen bonding, under equilibrium conditions. As ensembles of molecules rapidly lose coherence, we cannot extrapolate bulk data to single-molecule events under non-equilibrium conditions, more relevant to the dynamics of biological systems. We present a new method that exploits the high force resolution of optical tweezers to measure at the single molecule level the mechanical strength of a hydrogen bonded host-guest pair out of equilibrium and under near-physiological conditions. We utilize a DNA reporter to unambiguously isolate single binding events. The Hamilton receptor-cyanuric acid host-guest system is used as a test bed. The force required to dissociate the host-guest system is ∼17 pN and increases with the pulling rate as expected for a system under non-equilibrium conditions. Blocking one of the hydrogen bonding sites results in a significant decrease of the force-to-break by 1-2 pN, pointing out the ability of the method to resolve subtle changes in the mechanical strength of the binding due to the individual H-bonding components. We believe the method will prove to be a versatile tool to address important questions in supramolecular chemistry.

    An elaborately designed pyridinium-functionalized octanuclear zinc(II) coordination container 1-Zn was prepared through the self-assembly of Zn 2+ , p-tert-butylsulfonylcalix[4]arene, and pyridinium-functionalized angular flexible dicarboxylate linker (H 2 BrL1). The structure was determined by a single-crystal X-ray diffractometer. 1-Zn displays highly sensitive and specific recognition to 2-picolylamine as revealed by drastic blueshifts of the absorption and emission spectra, ascribed to the decrease of intramolecular charge transfer (ICT) character of the container and the occurrence of intermolecular charge transfer between the host and guest molecules. The intramolecular charge transfer plays a key role in the modulation of the electronic properties and is tunable through endo-encapsulation of specific guest molecules. © 2018 Wiley-VCH Verlag GmbH & Co.

  16. Knowledge of Deaths in Hotel Rooms Diminishes Perceived Value and Elicits Guest Aversion.

    Bering, Jesse M; Curtin, Emma R; Jong, Jonathan

    2017-01-01

    Guest deaths are an inevitable aspect of the hospitality industry. In Study 1, participants read a vignette in which the previous guest died of natural causes, suicide, or homicide. Those who learned of a death (a) saw the room as less valuable, (b) opted to stay in a more basic room in which no death occurred, despite both rooms being offered for free, and (c) anticipated feeling uneasy when imagining an overnight stay. In Study 2, we investigated the persistence of this bias. Perceived room value and anticipatory well-being can be expected to return to baseline levels only many years after the death event. Similar to "stigmatized properties" in real estate, these data confirm an irrational and recalcitrant cognitive bias surrounding consumers' views of death-affected hotel rooms.

  17. Toward Improved Force-Field Accuracy through Sensitivity Analysis of Host-Guest Binding Thermodynamics

    2015-01-01

    Improving the capability of atomistic computer models to predict the thermodynamics of noncovalent binding is critical for successful structure-based drug design, and the accuracy of such calculations remains limited by non-optimal force field parameters. Ideally, one would incorporate protein-ligand affinity data into force field parametrization, but this would be inefficient and costly. We now demonstrate that sensitivity analysis can be used to efficiently tune Lennard-Jones parameters of aqueous host-guest systems for increasingly accurate calculations of binding enthalpy. These results highlight the promise of a comprehensive use of calorimetric host-guest binding data, along with existing validation data sets, to improve force field parameters for the simulation of noncovalent binding, with the ultimate goal of making protein-ligand modeling more accurate and hence speeding drug discovery.

    Langston University, a Historically Black University located at Langston, Oklahoma, has a computing and information science program within the Langston University Division of Business. Since 1984, Langston University has participated in the Historically Black College and University program of the U.S. Department of Interior, which provided education, training, and funding through a combined earth-science and computer-technology cooperative program with the U.S. Geological Survey (USGS). USGS personnel have presented guest lectures at Langston University since 1984. Students have been enthusiastic about the lectures, and as a result of this program, 13 Langston University students have been hired by the USGS on a part-time basis while they continued their education at the University. The USGS expanded the offering of guest lectures in 1992 by increasing the number of visits to Langston University, and by inviting participation of speakers from throughout the country. The objectives of the guest-lecture series are to assist Langston University in offering state-of-the-art education in the computer sciences, to provide students with an opportunity to learn from and interact with skilled computer-science professionals, and to develop a pool of potential future employees for part-time and full-time employment. This report includes abstracts for guest-lecture presentations during 1992-93 school year.

    At the Hilton Columbus Downtown hotel in Ohio, DOE's Better Buildings Alliance conducted a demonstration of Next Generation Luminaires-winning downlights installed in all guest rooms and suites prior to the hotel's 2012 opening. After a post-occupancy assessment, the LED downlights not only provided the aesthetic appearance and dimming functionality desired, but also provided 50% energy savings relative to a comparable CFL downlight and enabled the lighting power to be more than 20% below that allowed by code. This document is a summary case study of the report.

    Zhou, Zhuxian; Han, Zhen; Lu, Zheng-Rong

    2016-04-01

    The clinical application of nanoparticular Gd(III) based contrast agents for tumor molecular MRI has been hindered by safety concerns associated with prolonged tissue retention, although they can produce strong tumor enhancement. In this study, a targeted well-defined cyclodextrin-based nanoglobular contrast agent was developed through self-assembly driven by host-guest interactions for safe and effective cancer molecular MRI. Multiple β-cyclodextrins attached POSS (polyhedral oligomeric silsesquioxane) nanoglobule was used as host molecule. Adamantane-modified macrocyclic Gd(III) contrast agent, cRGD (cyclic RGDfK peptide) targeting ligand and fluorescent probe was used as guest molecules. The targeted host-guest nanoglobular contrast agent cRGD-POSS-βCD-(DOTA-Gd) specifically bond to αvβ3 integrin in malignant 4T1 breast tumor and provided greater contrast enhancement than the corresponding non-targeted agent. The agent also provided significant fluorescence signal in tumor tissue. The histological analysis of the tumor tissue confirmed its specific and effective targeting to αvβ3 integrin. The targeted imaging agent has a potential for specific cancer molecular MR and fluorescent imaging. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available The sustainable development of the festival depends on the support and participation of residents and tourists. There are a number of practical and theoretical gaps regarding the hosts and guests in festival literature. This study attempts to fill the host–guest gap based on the theory of reasoned action to construct and exam a relationship model. Taking the 2016 Summer Festival during busy season as an example in Hualien, 1165 questionnaires were valid, and data were analyzed by SEM (structural equation modeling. Results showed that the hosts had higher perception than the guests in terms of the festival benefits, identity, and support. This study has two concept models: the guest model and the host model. In the host model, the local-development benefits have more positive relationships to affect the festival support and festival identity than the recreation-experience benefits. On the other hand, the recreation-experience benefits could affect the festival support, but the festival identity could not in the guest model. The results of this study indicate that the festival organizers or the public sectors must be pay attention to the viewpoints of the guests and hosts in order to achieve the sustainable development objectives.

  14. Standard Javanese Causatives in online editorials and short stories

    Directory of Open Access Journals (Sweden)

    Noor Malihah

    2014-06-01

    Full Text Available This paper explores the distinctive features of the standard Javanese causatives in on-line editorials and short stories. This research is based on written corpus. This written corpus was compiled from articles published in an online newspaper Solo Pos. To analyze the corpus, I have developed a system of manual annotation to identify the features of verb transitivity, the animacy and humanness of the verb, the presence of active, passive and ergative-like clauses and the number of other grammatical and semantic features using a system of tags. Using this annotation, I analyze the data based on dua anlaysis: genre analysis, functional analysis using a quantitative method. The findings show that genre influences the selection of causative types (markers. Also, there exists gawe used as a verb of causation in both editorials and short stories which contradicts to the canonical rule of the Javanese active verb and Malihah’s (2014 findings. The finding also shows that the standard Javanese causative in online editorials and short stories occurs with intransitive verbs. The last finding is that active clause is the relative prominent type of clause which occurs in all marker. In conclusion, the above findings have made contributions to knowledge to Javanese grammar.

  20. "I’m a poor lonesome cowboy and a long way from home…": Serbian Documentary Films about Guest Workers

    Directory of Open Access Journals (Sweden)

    Marija Krstić

    2016-02-01

    Full Text Available In this paper I will analyze Serbian documentary films about guest workers dating from the last decade of the 20th and the first decade of the 21st century, using the perspective of visual anthropology. I question the popular cultural notions about guest workers in films Весеље у Ждрелу (A Celebration in Zdrelo by author Kamenko Katic, Звона позне јесени (The Bells of Late Autumn by author Zoran Milenovic, Кад је Милорад удавао ћерку (When Milorad Gave His Daughter in Marriage by author Vladimir Milisavljevic, Странац тамо, странац овде (A Foreigner There, a Foreigner Here by author Sandra Mandic and 242 метра живота (242 Meters of Life by author Novica Savic. The films deal with a number of issues: the economic aspects of guest workers’ lives, their liminal character, the issues of the second and third generations of guest workers, going away "temporarily" to work, and religious rituals. Even though the films were made recently, they all follow the lives of Vlach and Serbian, or rather Yugoslav guest workers who left to find temporary work abroad in Western Europe in the 1960’s and 1970’s. This serves the purpose of avoiding to deal with contemporary reasons for emigrating from Serbia and thus the possible critiques of current regimes or policies in power at the time the films were made.

  4. Terrorism in the Basque press (1990, 2000, 2008 and 2009. Analysis of newspaper editorials about ETA’s fatal attacks

    Directory of Open Access Journals (Sweden)

    José-María Caminos-Marcet, Ph.D.

    2013-01-01

    Full Text Available This article presents an analysis of the editorials published by the Basque press in 1990, 2000, 2008 and 2009, when ETA carried out fatal attacks. The objective is to examine the treatment given by the different Basque newspapers to terrorism in their most important opinion texts, which reflect their ideology. The initial hypothesis is that the editorial line used by the Basque press to address ETA’s attacks has changed remarkably during the analysed years, going from the virtual absence of editorials to the use of editorials as active instruments in the fight against violence. By 2009, the Basque press had finally defined its strategy to combat ETA’s terrorism, and this was perfectly reflected in their editorials.

  5. “The Poet, He Nothing Affirms, and Therefore Never Lieth”? An Analysis of the Editorial Fiction

    Directory of Open Access Journals (Sweden)

    Eva-Maria Konrad

    2015-06-01

    Full Text Available Is the editorial fiction a possible challenge to Sir Philip Sidney’s famous defence of the poets? Predicated on an assertion-based definition of lying, this paper discusses two historically consecutive versions of this phenomenon: A closer analysis of Gérard Genette’s category of the disavowing authentic authorial preface reveals that Genette’s arguments cannot defend editorial fictions written by ‘author-editors’ against accusations of lying. Rather, this first version of editorial fictions occasionally embodies lies for which the authors are to be held accountable. Editorial fictions written by ‘character-editors’, in contrast, do not meet the conditions of the assertion-based account of lying with the result that, in this case, neither the author nor the ‘character-editor’ can be accused of lying.

    Fan, Hao; Li, Hui; Wang, Qingjiang; He, Pingang; Fang, Yuzhi

    2012-05-15

    A sensitive electrochemical aptasensor for thrombin detection is presented based on the host-guest recognition technique. In this sensing protocol, a 15 based thrombin aptamer (ab. TBA) was dually labeled with a thiol at its 3' end and a 4-((4-(dimethylamino)phenyl)azo) benzoic acid (dabcyl) at its 5' end, respectively, which was previously immobilized on one Au electrode surface by AuS bond and used as the thrombin probe during the protein sensing procedure. One special electrochemical marker was prepared by modifying CdS nanoparticle with β-cyclodextrins (ab. CdS-CDs), which employed as electrochemical signal provider and would conjunct with the thrombin probe modified electrode through the host-guest recognition of CDs to dabcyl. In the absence of thrombin, the probe adopted linear structure to conjunct with CdS-CDs. In present of thrombin, the TBA bond with thrombin and transformed into its special G-quarter structure, which forced CdS-CDs into the solution. Therefore, the target-TBA binding event can be sensitively transduced via detecting the electrochemical oxidation current signal of Cd of CdS nanoparticles in the solution. Using this method, as low as 4.6 pM thrombin had been detected. Copyright © 2012 Elsevier B.V. All rights reserved.

  13. Women are underrepresented on the editorial boards of journals in environmental biology and natural resource management

    Directory of Open Access Journals (Sweden)

    Alyssa H. Cho

    2014-08-01

    Full Text Available Despite women earning similar numbers of graduate degrees as men in STEM disciplines, they are underrepresented in upper level positions in both academia and industry. Editorial board memberships are an important example of such positions; membership is both a professional honor in recognition of achievement and an opportunity for professional advancement. We surveyed 10 highly regarded journals in environmental biology, natural resource management, and plant sciences to quantify the number of women on their editorial boards and in positions of editorial leadership (i.e., Associate Editors and Editors-in-Chief from 1985 to 2013. We found that during this time period only 16% of subject editors were women, with more pronounced disparities in positions of editorial leadership. Although the trend was towards improvement over time, there was surprising variation between journals, including those with similar disciplinary foci. While demographic changes in academia may reduce these disparities over time, we argue journals should proactively strive for gender parity on their editorial boards. This will both increase the number of women afforded the opportunities and benefits that accompany board membership and increase the number of role models and potential mentors for early-career scientists and students.

    Full Text Available Introduction. This article analyses the main features and degree of adaptation of the editorials of five newspapers from different European countries to the online environment. Methods. The study is based on the content analysis of the editorials published in the online editions of El País, The Times, Le Monde, Diario de Noticias and Corriere della Sera. Results. In the sample of online newspapers, the editorial genre maintains a privileged position in the online version and can be differentiated from the opinion pieces. In addition, this section retains its function as the institutional voice of the newspapers. Discussion. Despite the importance of the editorial, its role as shaper of public opinion in relation to current affairs is overshadowed by its role as political actor. Conclusions. The online editorial retains the traditional content and format features of the genre, and shows little adaptation to the internet platform and its possibilities to enable citizens’ participation.

    We approach the problem of "predatory" journals and publishers from the perspective of small scientific communities and small journals that may sometimes be perceived as "predatory". Among other characteristics of "predatory" journals two most relevant are their business model and the quality of the editorial work. We analysed 444 Croatian open access (OA) journals in the Hrčak (portal of Croatian scientific journals) digital journal repository for the presence of article processing charges as a business model and the transparency of editorial policies. The majority of journals do not charge authors or require submission or article processing charges, which clearly distinguishes them from "predatory" journals. Almost all Hrčak OA journals have publicly available information on editorial boards, including full names and affiliations, and detailed contact information for the editorial office at the Hrčak website. The journal names are unique and cannot be easily confused with another journal or intend to mislead about the journal's origin. While most journals provide information on peer review process, many do not provide guidelines for reviewers or other editorial and publication ethics standards. In order to clearly differentiate themselves from predatory journals, it is not enough for journals from small research communities to operate on non-commercial bases, but also to have transparent editorial policies.

  7. Host–Guest Chirality Interplay: A Mutually Induced Formation of a Chiral ZMOF and Its Double-Helix Polymer Guests

    2016-01-12

    A novel homochiral zeolite-like metal-organic framework (ZMOF), [(Cu4I4) (dabco)2]·[Cu2(bbimb)]·3DMF (JLU-Liu23, dabco =1,4-diazabicyclo[2.2.2]-octane, H2bbimb =1,3-bis(2-benzimidazol)benzene, DMF = N,N-dimethylformamide), has been successfully constructed to host unprecedented DNA-like [Cu2(bbimb)]n polymers with double-helicity. The host-guest chirality interplay permitted the induced formation of an unusual gyroid MOF with homochirality and helical channels in the framework for the first time, JLU-Liu23. Importantly, the enantiomeric pairs (23P, 23M) can be promoted and isolated in the presence of appropriate chiral inducing agents, affording enantioselective separation of chiral molecules as well as small gas molecules. © 2016 American Chemical Society.

    Thermoresponsive water-soluble polymers are of great importance since they typically show a lower critical solution temperature (LCST) in aqueous media. In this research, the LCST change in broad temperature ranges of copolymers composed of natural glycyrrhetinic acid (GA)-based methacrylate and N,N'-dimethylacrylamides (DMAs) was investigated as a function of the concentration and the content of GA pendants. By complexation of GA pendants with β-cyclodextrin (β-CD), a side-chain polypseudorotaxane was obtained, which exhibited a significant increase in the LCST of copolymers. Moreover, the precisely reversible control of the LCST behavior was realized through adding a competing guest molecule, sodium 1-admantylcarboxylate. This work illustrates a simple and effective approach to endow water-soluble polymers with broad temperature tunability and helps us further understand the effect of a biocompatible host-guest complementary β-CD/GA pair on the thermoresponsive process. © 2017 Wiley-VCH Verlag GmbH & Co.

  9. Theoretical exploration of the nanoscale host-guest interactions between [n]cycloparaphenylenes (n = 10, 8 and 9) and fullerene C₆₀: from single- to three-potential well.

    The nanoscale host-guest interactions between [n]cycloparaphenylene ([n]CPP; n = 10, 8 and 9) nano-ring and fullerene C60 were explored theoretically. It is found that relatively small variations in the sizes of the [n]CPP host lead to very significant changes in encapsulation property toward the fullerene C60 guest. Expectedly, one stable inclusion-configuration of [10]CPP⊃C60 and one floating-configuration of [8]CPP⊃C60 are located on the potential surfaces of the two complexes, respectively. Unexpectedly, besides a floating-configuration (F-[9]CPP⊃C60), another stable inclusion-configuration (I-[9]CPP⊃C60) is also located on the potential surface of [9]CPP⊃C60 host-guest complex. Interaction energies and natural steric analysis show that these complexes are stabilized by balancing concave-convex π-π attractive and steric repulsive host-guest interactions. In contrast, the steric repulsive energy (Es) between host and guest of I-[9]CPP⊃C60 is as high as 233.12 kJ mol(-1), which is much larger than those in other complexes. The movements of C60 guest through the cavities of [n]CPP host (n = 10, 8 and 9) are simulated by calculating the energy profile, and the results interestingly reveal that the encapsulation of C60 by [10]CPP is in the manner of a single-potential well, by [8]CPP in the manner of a double-potential well, and by [9]CPP in the special manner of a three-potential well. We predict that the movement of C60 guest through the cavity of [9]CPP host should be experimentally observable owing to the relatively low energy barrier (<50 kJ mol(-1), M06-2X/6-31G(d)). Charge population analysis shows that an obvious charge transfer between host and guest takes place during the formation of I-[9]CPP⊃C60, which is different from those during the formation of [8]CPP⊃C60, [10]CPP⊃C60 and F-[9]CPP⊃C60. Additionally, the host-guest interaction regions were detected and visualized in real space based on the electron density and reduced density

    Full Text Available The scholars comprising journal editorial boards play a critical role in defining the trajectory of knowledge in their field. Nevertheless, studies of editorial board composition remain rare, especially those focusing on journals publishing research in the increasingly globalized fields of science, technology, engineering, and math (STEM. Using metrics for quantifying the diversity of ecological communities, we quantified international representation on the 1985-2014 editorial boards of 24 environmental biology journals. Over the course of 3 decades, there were 3,827 unique scientists based in 70 countries who served as editors. The size of the editorial community increased over time-the number of editors serving in 2014 was 4-fold greater than in 1985-as did the number of countries in which editors were based. Nevertheless, editors based outside the "Global North" (the group of economically developed countries with high per capita gross domestic product [GDP] that collectively concentrate most global wealth were extremely rare. Furthermore, 67.18% of all editors were based in either the United States or the United Kingdom. Consequently, geographic diversity-already low in 1985-remained unchanged through 2014. We argue that this limited geographic diversity can detrimentally affect the creativity of scholarship published in journals, the progress and direction of research, the composition of the STEM workforce, and the development of science in Latin America, Africa, the Middle East, and much of Asia (i.e., the "Global South".

  15. Good editorial practice: editors as educators.

    2001-04-01

    There may be valuable research going on in the developing and financially less-privileged countries, but it usually does not reach international visibility, in spite of a large number of scientific journals in these countries. Such journals are not only invisible but, by perpetuating a vicious circle of inadequacy, may be directly damaging to the local science and research culture. We call for an international action to help journal editors in less privileged countries. International associations of editors may be leaders of these activities by defining, promoting, and perhaps controlling good editorial practice, as a main criterion for international recognition of a journal. However, the editors of small journals have the power and moral obligation to become a stronghold of quality and advancement in their scientific community. Their educational "tools" are editorial integrity and author-friendly policy. Editors can teach the authors study design, statistical analysis, precision, punctuality, research integrity, style and format of writing, and other aspects of scientific communication. The editors of "big", mainstream scientific journals can act as global educators, teaching and providing guidance to editors of small journals. The editors from developed countries as leaders, and editors from less advantageous environments as teachers are the key figures in shaping research communication in less privileged scientific communities.

    Full Text Available In the hotel industry, it is a well-known fact that, despite of quality and variety of services provided, there is a low probability that the guests will return. This research is focused on identifying the basic factors of the hotel offer, which could determine the influence on the correlation between the guests’ satisfaction and the probability of their return. The objective of the article is to explore the relationship between the guests’ satisfaction with the quality hotel services in total (including the tourist offer of the place and the probability of his return to the same destination. The questionnaire method was applied in the survey, and the data were analysed based on factor analysis. Thereafter, the model for forecasting the probability of the guests returning to the destination was established, by using the example of Montenegrin tourism. The model represents a defined framework for the guest’s decision-making process. It identifies two main characteristics of guest experiences: satisfaction and rated quality (of the destination’s overall hotel service and tourist offer. The same model evaluates the impact of the above factors on the probability of the guests’ returning to the same destination. The starting hypothesis was the existence of a high degree of correlation between the guests’ satisfaction (with the destination’s hotel services and tourist offer and the probability of returning to the selected Montenegrin destinations. The research confirmed the above-mentioned hypothesis. The results have revealed that there are significant differences in perceived quality, i.e. satisfaction between the target groups of Eastern and Western European tourists

    We report the inclusion of carboxy- and amine-substituted molecular nanodiamonds (NDs) adamantane, diamantane, and triamantane by β-cyclodextrin and γ-cyclodextrin (β-CD and γ-CD), which have particularly well-suited hydrophobicity and symmetry for an optimal fit of the host and guest molecules. We studied the host-guest interactions in detail and generally observed 1:1 association of the NDs with the larger γ-CD cavity, but observed 1:2 association for the largest ND in the series (triamantane) with β-CD. We found higher binding affinities for carboxy-substituted NDs than for amine-substituted NDs. Additionally, cyclodextrin vesicles (CDVs) were decorated with d-mannose by using adamantane, diamantane, and triamantane as non-covalent anchors, and the resulting vesicles were compared with the lectin concanavalin A in agglutination experiments. Agglutination was directly correlated to the host-guest association: adamantane showed lower agglutination than di- or triamantane with β-CDV and almost no agglutination with γ-CDV, whereas high agglutination was observed for di- and triamantane with γ-CDV. © 2017 Wiley-VCH Verlag GmbH & Co.

    2004-01-01

    Science and scientific thinking have not made a substantial impact on educational practice. In this discussion, we examine the relationship between science and education and delineate four reasons for characterizing science as an uninvited guest in schools: (a) Science is not highly regarded in society; (b) good science and bad science are often mistaken for one another; (c) the amount of current data is overwhelming; and (d) science is not easy for those who practice it (researchers), those who translate it (teacher educators), or those who consume it (teachers). We suggest several strategies to improve this relationship, including promoting standards of educational practice, emphasizing the role of teacher educators as translators of the research base into classroom practice, and linking student outcomes with the use of effective instructional practices.

    Participation of women in the medical profession has increased during the past four decades, but issues of concern persist regarding disparities between the sexes in academic medicine. Advancement is largely driven by peer-reviewed original research, so we sought to determine the representation of female physician-investigators among the authors of selected publications during the past 35 years. Original articles from six prominent medical journals--the New England Journal of Medicine (NEJM), the Journal of the American Medical Association (JAMA), the Annals of Internal Medicine (Ann Intern Med), the Annals of Surgery (Ann Surg), Obstetrics & Gynecology (Obstet Gynecol), and the Journal of Pediatrics (J Pediatr)--were categorized according to the sex of both the first and the senior (last listed) author. Sex was also determined for the authors of guest editorials in NEJM and JAMA. Data were collected for the years 1970, 1980, 1990, 2000, and 2004. The analysis was restricted to authors from U.S. institutions holding M.D. degrees. The sex was determined for 98.5 percent of the 7249 U.S. authors of original research with M.D. degrees. The proportion of first authors who were women increased from 5.9 percent in 1970 to 29.3 percent in 2004 (P<0.001), and the proportion of senior authors who were women increased from 3.7 percent to 19.3 percent (P<0.001) during the same period. The proportion of authors who were women increased most sharply in Obstet Gynecol (from 6.7 percent of first authors and 6.8 percent of senior authors in 1970 to 40.7 percent of first authors and 28.0 percent of senior authors in 2004) and J Pediatr (from 15.0 percent of first authors and 4.3 percent of senior authors in 1970 to 38.9 percent of first authors and 38.0 percent of senior authors in 2004) and remained low in Ann Surg (from 2.3 percent of first authors and 0.7 percent of senior authors in 1970 to 16.7 percent of first authors and 6.7 percent of senior authors in 2004).

  10. Selectivity and stoichiometry boosting of beta-cyclodextrin in cationic/anionic surfactant systems: when host-guest equilibrium meets biased aggregation equilibrium.

    Cationic surfactant/anionic surfactant/beta-CD ternary aqueous systems provide a platform for the coexistence of the host-guest (beta-CD/surfactant) equilibrium and the biased aggregation (monomeric/aggregated surfactants) equilibrium. We report here that the interplay between the two equilibria dominates the systems as follows. (1) The biased aggregation equilibrium imposes an apparent selectivity on the host-guest equilibrium, namely, beta-CD has to always selectively bind the major surfactant (molar fraction > 0.5) even if binding constants of beta-CD to the pair of surfactants are quite similar. (2) In return, the host-guest equilibrium amplifies the bias of the aggregation equilibrium, that is, the selective binding partly removes the major surfactant from the aggregates and leaves the aggregate composition approaching the electroneutral mixing stoichiometry. (3) This composition variation enhances electrostatic attractions between oppositely charged surfactant head groups, thus resulting in less-curved aggregates. In particular, the present apparent host-guest selectivity is of remarkably high values, and the selectivity stems from the bias of the aggregation equilibrium rather than the difference in binding constants. Moreover, beta-CD is defined as a "stoichiometry booster" for the whole class of cationic/anionic surfactant systems, which provides an additional degree of freedom to directly adjust aggregate compositions of the systems. The stoichiometry boosting of the compositions can in turn affect or even determine microstructures and macroproperties of the systems.

    Full Text Available Dear IEJEE reader, You are holding the third issue of volume one of International Electronic Journal of Elementary Education (IEJEE, one of the youngest and most exciting electronic journals focusing on the contemporary issues in elementary education. Approximately one tenth of today’s world population has one or another way relationship with elementary education. Different socio-cultural issues, tough economic challenges and changing policies around the world affect the educational conditions for elementary students. Different countries and geographic areas steady are facing different challenges with regard to their teaching-learning agendas. On the other hand we are observing a common global interest: All the central and local educational authorities want to create better teaching conditions for elementary teachers and better learning conditions for the elementary students. Another global interest is to have access to research-based knowledge which has high quality and at the same time is relevant. I believe that IEJEE is fulfilling an important mission with that regard. I owe many thanks to all the researchers who have made their contributions to the previous issues and this third issue of IEJEE. Publishing an international scientific journal is a demanding job.

    Japan ranks extremely low in global ranking of gender equality. It is not easy for female doctors to acquire leadership positions in member societies of the Japanese Association of Medical Science (JAMS). Very few women are included on editorial boards of English medical journals in Japan. Furthermore, until last year, there had been no female editors in English language journals of surgical societies. The qualifications and criteria for selecting editorial board members of medical journals should be clarified. Medical journals in Japan would gain diversity by including women on editorial boards in the same proportion as women membership in the corresponding medical societies.

    2-(Propylamino)acetamide of aniline (1a), and bis-2-(propylamino)acetamide of ortho- (1b) and para-(1c) phenylenediamine form host-guest complexes with CB[6], CB[7] and CB[8] as evidenced by the variations in the (1)H NMR spectroscopy chemical shifts and observation in MALDI-TOF-MS and ESI-MS of ions at the corresponding mass. Binding constants for the 1:1 complexes were estimated from fluorescence titrations and were in the range 10(5)-10(6)M(-1). Models based on molecular mechanics for these supramolecular complexes are provided. In spite of the different geometries arising from the ortho- or para-substitution, phenylenediamides form complexes of similar strength in which the hydrophobic alkyl chains are accommodated inside the host cavity. Formation of these host-guest complexes in the solid state was also achieved by modifying an aminopropyl silica with chloroacetanilides and preparing three silica having analogues of compounds 1a-c anchored to the solid particles. Titrations showed, however, that these solids can adsorb a large percentage of CBs by unselective interactions that are not related to the formation of inclusion complexes.

  17. The Metaphors on International Intervention: A Discourse Analysis of the Sri Lankan English Newspaper Editorials

    Directory of Open Access Journals (Sweden)

    Jeyaseelan Gnanaseelan

    2015-07-01

    Full Text Available The metaphors used in the Sri Lankan English newspaper editorials during the peace talk time (2001-2007 commenting on the international intervention in the Sri Lankan ethnic conflict reveal community based ideological and attitudinal positions of the newspapers published in Sri Lanka. Metaphors literally contribute to our understanding of reality. The frames and scripts used for legitimization and de-legitimization of the issues related to international intervention and facilitation in the peace talk, peace process and monitoring the ceasefire bring out certain realities comfortable to certain people, groups or communities. The binary positions projected in the editorial discourse are identified. Discourse constitutes power in constructing ideational, textual and interpersonal constructs which are ideological. It can transmit and even legitimize power in society. During the peace talk time, the editorials are expected to develop constructive discourse on conflict intervention and resolution to make a positive impact on legislative changes but they display ‘ethno-nationalist’ tendencies. The study analyzes whether the media has been a part of the problem or a part of the solution. Since newspaper and editorial discourses are the constructions of journalists and editors of the elites, the biased ideologies are “hidden or subtle in expressions and often revealed in mild forms”. This study takes up selected editorials of the Sri Lankan English newspapers which appeared mainly during the Memorandum of Understanding between the Sri Lankan government and the Liberation Tigers of Tamil Eezham during that period, to relate the discourse themes with rhetorical and metaphorical features.

  2. Smart protein biogate as a mediator to regulate competitive host-guest interaction for sensitive ratiometric electrochemical assay of prion

    Science.gov (United States)

    Yu, Peng; Zhang, Xiaohua; Zhou, Jiawan; Xiong, Erhu; Li, Xiaoyu; Chen, Jinhua

    2015-11-01

    A novel competitive host-guest strategy regulated by protein biogate was developed for sensitive and selective analysis of prion protein. The methylene blue (MB)-tagged prion aptamer (MB-Apt) was introduced to the multiwalled carbon nanotubes-β-cyclodextrins (MWCNTs-β-CD) composites-modified glassy carbon (GC) electrode through the host-guest interaction between β-CD and MB. In the absence of prion, MB-Apt could be displaced by ferrocenecarboxylic acid (FCA) due to its stronger binding affinity to β-CD, resulting in a large oxidation peak of FCA. However, in the presence of prion, the specific prion-aptamer interaction drove the formation of protein biogate to seal the cavity of β-CD, which hindered the guest displacement of MB by FCA and resulted in the oxidation peak current of MB (IMB) increased and that of FCA (IFCA) decreased. The developed aptasensor showed good response towards the target (prion protein) with a low detection limit of 160 fM. By changing the specific aptamers, this strategy could be easily extended to detect other proteins, showing promising potential for extensive applications in bioanalysis.

I am excited to begin my new role as Editor-in-Chief at a time when the journal is functioning well and the Editorial Team has a sufficient amount of experience to confidently manage the publishing process, but is young enough to be open to new ideas and make changes without too much angst. Mostly, I hope that the journal can quickly respond to the needs of our readers, authors, and everyone who works to make the journal a success. I am always pleasantly surprised when we put out calls for volunteer help and are overwhelmed with the number of people who are interested in contributing to the journal. I definitely believe that the more people who are involved, the better the end result will be, since more ideas and points of view only strengthen the quality of our endeavour.To kick off this first issue of 2009, we debut a new section called Using Evidence in Practice. This section features brief reports of LIS practitioners' use of evidence to assist with decision making. We hope that this section will attract all the practitioners out there who are trying to incorporate evidence into their daily practice, and want to share some of their successes or struggles with the evidence-based process. The section follows a structured format, so that readers can always expect to be provided with information on a project that includes an overview of the setting, problem, evidence that was used, how change was implemented, the outcome of those changes,and the author’s reflections on trying to implement change by using evidence. I hope these brief reports of “real-life” stories inspire and provide ideas for our readers. Our first article in this section looks at one library’s exploration of the use of folksonomy tags and what the evidence they gathered might mean for the cataloguing of their electronic dissertations and theses collection.I am pleased to announce that we have a new

    h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups. Among the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median. Our data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals. Copyright © 2017 The Association of University Radiologists.

    Monomolecular drug carriers based on calix[n]-arenes and -resorcinarenes containing the interior cavity can enhance the affinity and specificity of the osteoporosis inhibitor drug zoledronate (ZOD). In this work we investigate the suitability of nine different calix[4]-arenes and -resorcinarenes based macrocycles as hosts for the ZOD guest molecule by conducting {\\it ab initio} density functional theory calculations for structures and energetics of eighteen different host-guest complexes. For the optimized molecular structures of the free, phosphonated, sulfonated calix[4]-arenes and -resorcinarenes, the geometric sizes of their interior cavities are measured and compared with those of the host-guest complexes in order to check the appropriateness for host-guest complex formation. Our calculations of binding energies indicate that in gaseous states some of the complexes might be unstable but in aqueous states almost all of the complexes can be formed spontaneously. Of the two different docking ways, the insertion of ZOD with the \\ce{P-C-P} branch into the cavity of host is easier than that with the nitrogen containing heterocycle of ZOD. The work will open a way for developing effective drug delivering systems for the ZOD drug and promote experimentalists to synthesize them.

    The present work articulates the supramolecular interaction and the formation of host-guest complex between the biologically active hydrophobic coumarin derivative and cyclodextrins by using several spectroscopic, calorimetric and microscopic techniques. All the studies clearly revealed that in presence of cyclodextrins (CDs), coumarin forms 1:1 stoichiometric complex. From all the study, we have found that with gradual increasing the cavity diameter of the hosts, the binding efficiency of the complexes gradually increases. The small population of the non emissive twisted intramolecular charge transfer (TICT) state of coumarin molecule turns into highly emissive in presence of γ-CD owing to its greater cavity diameter. The emissive TICT band is not found in β-CD complex due to its comparative small hydrophilic exterior and less polar environment. The present finding also interpret the perturbation effect of urea on host-guest complexes. In the presence of urea, the TICT emissive band of γ-CD is completely diminished. From, {sup 1}H NMR study it was observed that –NEt{sub 2} moiety of 7-DCCAE molecule is deeply buried inside the hydrophobic cavity of the CDs and forms host-guest complexes. Isothermal titration calorimetry measurement also indicates the formation of 1:1 host-guest complexes.

  20. Editorial: How is the money to combat human trafficking spent?

    2014-09-01

    This edition of the Anti-Trafficking Review explores what happens to the money that is allocated by governments and private donors to stop human trafficking and to assist people who have been trafficked. It has been an honour to play the role of guest editor, though it has not been easy to steer a route between amazement (at the sums apparently involved, concern (at the lack of real insight into how money is allocated and spent and cynicism (at what appear to be rather modest achievements. It was challenging for potential authors to choose a method of analysing anti-trafficking spending. Should they simply describe what money is available and the drawbacks of the ways which donors make it available to organisations to use? Some authors take this descriptive approach. Should articles be about the efficiency and effectiveness of aid flows in general, in which case the shortcomings in anti-trafficking funding may mirror the generic flaws in aid flows? Only one author (Ucnikova has tackled this. Or, should studies focus on the way the purse strings are controlled by a small number of donors who appear poorly informed about the needs of trafficked persons or the factors that cause them to be trafficked? Several of the articles touch on this (e.g. those of Hoff and Nwogu. Early on, it became apparent to the editorial team that people working for large organisations with anti-trafficking programmes were wary of contributing articles on this topic. In this sense, although the Anti-Trafficking Review aims to promote public debate, we have not yet found the best way of opening up a debate about funding, for practitioners evidently fear that writing about their own sources of funding could result in the tap being turned off! So, it is mainly the Debate section that tackles the question of funding strategies. Even these contributions do not make assessments of the various actors involved (donors and the organisations they fund in as full and frank a way as is needed. The

  3. EDITORIAL: Greetings from the new Editor-in-Chief

    Science.gov (United States)

    Bhattacharya, P.

    2004-04-01

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

    The second half of the twentieth century and the beginning of the 2000s marked deep changes in the practice of pharmacy in Quebec. The editorials of Québec Pharmacie journal attest these changes on a 50-year period by relating power relationships, conflicts, problems and solutions that concerned pharmacists. This article proposes to analyze the editorial discourse of Québec Pharmacie journal between 1960 and 2013, and to grasp the evolution of the speech. To do so, we analyze the major topics addressed by the editorialists. It appears that Québec Pharmacie’s editorialists aimed the professionalization of pharmacy.

  7. Computational Calorimetry: High-Precision Calculation of Host–Guest Binding Thermodynamics

    Science.gov (United States)

    2015-01-01

    We present a strategy for carrying out high-precision calculations of binding free energy and binding enthalpy values from molecular dynamics simulations with explicit solvent. The approach is used to calculate the thermodynamic profiles for binding of nine small molecule guests to either the cucurbit[7]uril (CB7) or β-cyclodextrin (βCD) host. For these systems, calculations using commodity hardware can yield binding free energy and binding enthalpy values with a precision of ∼0.5 kcal/mol (95% CI) in a matter of days. Crucially, the self-consistency of the approach is established by calculating the binding enthalpy directly, via end point potential energy calculations, and indirectly, via the temperature dependence of the binding free energy, i.e., by the van’t Hoff equation. Excellent agreement between the direct and van’t Hoff methods is demonstrated for both host–guest systems and an ion-pair model system for which particularly well-converged results are attainable. Additionally, we find that hydrogen mass repartitioning allows marked acceleration of the calculations with no discernible cost in precision or accuracy. Finally, we provide guidance for accurately assessing numerical uncertainty of the results in settings where complex correlations in the time series can pose challenges to statistical analysis. The routine nature and high precision of these binding calculations opens the possibility of including measured binding thermodynamics as target data in force field optimization so that simulations may be used to reliably interpret experimental data and guide molecular design.

    The dissociation kinetics of mixed gas hydrates that contain propane as a guest molecule have been investigated. The mixed gas hydrates used in this work were artificially prepared using the binary gas mixture of methane-propane and the ternary gas mixture of methane-ethane-propane. The crystal structures and the guest compositions of the mixed hydrates were clearly identified by using Raman spectroscopy and gas chromatography. The dissociation rates of the gas hydrates observed under several isothermal and isobaric conditions were discussed with an analytical model. The isobaric conditions were achieved by pressurizing with mixed gases using buffer cylinders, which had similar compositions to those of the initial gases used for synthesizing each hydrate sample. Interestingly, the calculated result agreed well with the experimentally observed results only when the composition of the vapor phase was assumed to be identical with that of the hydrate phase instead of the bulk (equilibrium) gas composition

    Science.gov (United States)

    2016-01-01

    We study gender representation on the editorial boards of 435 journals in the mathematical sciences. Women are known to comprise approximately 15% of tenure-stream faculty positions in doctoral-granting mathematical sciences departments in the United States. Compared to this group, we find that 8.9% of the 13067 editorships in our study are held by women. We describe group variations within the editorships by identifying specific journals, subfields, publishers, and countries that significantly exceed or fall short of this average. To enable our study, we develop a semi-automated method for inferring gender that has an estimated accuracy of 97.5%. Our findings provide the first measure of gender distribution on editorial boards in the mathematical sciences, offer insights that suggest future studies in the mathematical sciences, and introduce new methods that enable large-scale studies of gender distribution in other fields.

    An amide-functionalized metal organic framework (MOF) material, MFM-136, shows a high CO 2 uptake of 12.6 mmol g -1 at 20 bar and 298 K. MFM-136 is the first example of an acylamide pyrimidyl isophthalate MOF without open metal sites and, thus, provides a unique platform to study guest binding, particularly the role of free amides. Neutron diffraction reveals that, surprisingly, there is no direct binding between the adsorbed CO 2 /CH 4 molecules and the pendant amide group in the pore. This observation has been confirmed unambiguously by inelastic neutron spectroscopy. This suggests that introduction of functional groups solely may not necessarily induce specific guest-host binding in porous materials, but it is a combination of pore size, geometry, and functional group that leads to enhanced gas adsorption properties.

    Full Text Available Communication between management and employees is very important in organizations. However, communication problems might be more felt in any media organization as a whole and in the local media staff in particular. It’s obvious that news workers have everyday communicative interaction with different newsmakers. The article deals with the study and analysis of the communicative interaction between the local editorial creative staff members. Internal and external organizational understanding data are considered. It is determined that the level of organizational communication development influences the local editorial success and employees’ performance. Mutual understanding as the basic criterion of effective communication has several forms. The subject of our study is organizational understanding, that is, a special type of editorial staff relationship which is limited by the boundaries of the organization and is essential for its successful functioning and development. The analysis of empirical data allowed to identify the main problematic aspects and to work out the recommendations for vertical and horizontal communication development.

    Nifedipine (NIF) is a hydrophobic drug widely used for treating cardiovascular diseases. This calcium channel blocker can present a higher apparent solubility by its inclusion into different cyclodextrins (CDs) as host-guest complexes. This paper focused on the structural investigation and dissolution behavior of inclusion complexes prepared with 2-hydroxypropyl-β-cyclodextrin (HPβCD) or β-cyclodextrin (βCD) and NIF. Drug amorphization was observed for HPβCD/NIF and βCD/NIF inclusion complexes by X-ray diffractometry (XRD). The sharp endothermic peak of NIF was not observed for these both host-guest complexes by differential scanning calorimetry (DSC). These results of XRD and DSC provide evidences of complexation between drug and the investigated CDs. 1H and saturation transfer difference nuclear magnetic resonance studies revealed the enhancement in the signal at 2.27 ppm for HPβCD/NIF and βCD/NIF inclusion complexes that corresponded to the methyl groups of NIF from the non-aromatic ring. This result suggested that non-aromatic ring of NIF was inserted into HPβCD and βCD cavities. Considering the mathematical simulations, it was observed that the inclusion process can occur in the both NH-in or NH-out forms. However, since it was used aqueous medium, it is possible to indicate that the obtained host-guest complexes HPβCD/NIF and βCD/NIF are in NH-in form which corresponded to the previous results obtained by 1H NMR experiments. Dissolution assays demonstrated that NIF inclusion complexes improved the drug release nevertheless without changing its biexponential release behavior. These host-guest complexes can be further used as feasible NIF carriers in solid dosage forms.

    h-index is useful for quantifying scholarly activity in medicine, but this statistic has not been extensively applied as a measure of productivity in anaesthesia. We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports(®). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus(®). Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (Pcitations, and citations per publication than those at journals with IF less than median. A significant correlation between the median h-index of a journal's editorial board members and its IF (h-index=3.01×IF+6.85; r( 2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

    Metal-organic frameworks (MOFs) are versatile materials highly regarded for their porous nature. Depending on the synthetic method, various guest molecules may remain in the pores or can be systematically loaded for various reasons. Herein, we present a study that explores the effect of guest molecules on the adsorption and reactivity of the MOF in both the gas phase and solution. The differences between guest molecule interactions and the subsequent effects on their activity are described for each system. Interestingly, different effects are observed and described in detail for each class of guest molecules studied. We determine that there is a strong effect of alcohols with the secondary building unit of UiO MOFs, while Lewis bases have an effect on the reactivity of the -NH 2 group in UiO-66-NH 2 and adsorption by the coordinatively unsaturated copper sites in HKUST-1. These effects must be considered when determining synthesis and activation methods of MOFs toward various applications.

    2016-12-01

    Full Text Available For an Italian guest, getting to know Slovenia as a tourist destination is inevitably connected with getting to know the Slovenian cuisine. Italians are a nation eagerly developing the culture of food, and therefore the gastronomic offer in a certain environment and at a certain time is for them often the basis for a comprehensive perception of the said destination. A good offer, a suitable marketing and an attractive presentation of typical Slovenian dishes play an important role in getting to know natural and cultural heritage as they can widen the knowledge about people and places, eliminate prejudice and strengthen intercultural cooperation. Kind and professional staff, knowledge of the language, civilisation, cultural habits, and differences may be the factors contributing to the assertion of local products and services, and to educating the users of restaurant and tourism services.

Hace aproximadamente 12 años surgió en el seno del Centro Centroamericano de Población la inquietud de ofrecer un espacio para dar a conocer los estudios poblacionales de nuestra región de una manera diferente. Queríamos crear una iniciativa más dinámica, que implicara una mayor rapidez en la gestión editorial, menores costos y un contacto más directo con los autores. Optamos entonces por una opción que apenas iniciaba sus primeros pasos en la Universidad de Costa Rica: la publicación electrónica. De hecho, la nuestra fue una de las primeras revistas electrónicas oficiales de esta noble institución académica. Se tuvo que librar una batalla para lograr romper con los esquemas tradicionales, en los cuales solamente la publicación impresa tenía validez, mientras que las electrónicas se tomaban como de baja calidad.

    Scientists who are members of an editorial board have been accused of preferentially publishing their scientific work in the journal where they serve as editor. Reputation and academic standing do depend on an uninterrupted flow of published scientific work and the question does arise as to whether publication mainly occurs in the self-edited journal. This investigation was designed to determine whether editorial board members of five urological journals were more likely to publish their research reports in their own rather than in other journals. A retrospective analysis was conducted for all original reports published from 2001-2010 by 65 editorial board members nominated to the boards of five impact leading urologic journals in 2006. Publications before editorial board membership, 2001-2005, and publications within the period of time as an editorial board member, 2006-2010, were identified. The impact factors of the journals were also recorded over the time period 2001-2010 to see whether a change in impact factor correlated with publication locality. In the five journals as a whole, scientific work was not preferentially published in the journal in which the scientists served as editor. However, significant heterogeneity among the journals was evident. One journal showed a significant increase in the amount of published papers in the 'own' journal after assumption of editorship, three journals showed no change and one journal showed a highly significant decrease in publishing in the 'own' journal after assumption of editorship.

  4. Synthesis, structure, and properties of a series of chiral tweezer-diamine complexes consisting of an achiral zinc(II) bisporphyrin host and chiral diamine guest: induction and rationalization of supramolecular chirality.

    2014-01-06

    We report here the synthesis, structure, and spectroscopic properties of a series of supramolecular chiral 1:1 tweezer-diamine complexes consisting of an achiral Zn(II) bisporphyrin (Zn2DPO) host and five different chiral diamine guests, namely, (R)-diaminopropane (DAP), (1S,2S)-diaminocyclohexane (CHDA), (S)-phenylpropane diamine (PPDA), (S)-phenyl ethylenediamine (PEDA), and (1R,2R)-diphenylethylene diamine (DPEA). The solid-state structures are preserved in solution, as reflected in their (1)H NMR spectra, which also revealed the remarkably large upfield shifts of the NH2 guest protons with the order Zn2DPO·DAP > Zn2DPO·CHDA > Zn2DPO·PPDA> Zn2DPO·PEDA ≫ Zn2DPO·DPEA, which happens to be the order of binding constants of the respective diamines with Zn2DPO. As the bulk of the substituent at the chiral center of the guest ligand increases, the Zn-Nax distance of the tweezer-diamine complex also increases, which eventually lowers the binding of the guest ligand toward the host. Also, the angle between the two porphyrin rings gradually increases with increasing bulk of the guest in order to accommodate the guest within the bisporphyrin cavity with minimal steric clash. The notably high amplitude bisignate CD signal response by Zn2DPO·DAP, Zn2DPO·CHDA, and Zn2DPO·PPDA can be ascribed to the complex's high stability and the formation of a unidirectional screw as observed in the X-ray structures of the complexes. A relatively lower value of CD amplitude shown by Zn2DPO·PEDA is due to the lower stability of the complex. The projection of the diamine binding sites of the chiral guest would make the two porphyrin macrocycles oriented in either a clockwise or anticlockwise direction in order to minimize host-guest steric clash. In sharp contrast, Zn2DPO·DPEA shows a very low amplitude bisignate CD signal due to the presence of both left- (dictated by the pre-existing chirality of (1R,2R)-DPEA) and right-handed screws (dictated by the steric differentiation at

    Full Text Available Crystal structures and dynamic rearrangements of one-dimensional coordination polymers with 4,4'-dipyridylsulfide (dps have been studied. Reaction of Ni(NO32·6H2O with dps in EtOH yielded [Ni(dps2(NO32]·EtOH (1, which had channels filled with guest EtOH molecules among the four Ni(dps2 chains. This coordination polymer reversibly transformed the channel structure responding to temperature variations. Immersion of 1 in m-xylene released guest EtOH molecules to yield a guest-free coordination polymer [Ni(dps2(NO32] (2a, which was also obtained by treatment of Ni(NO32·6H2O with dps in MeOH. On the other hand, removal of the guest molecules from 1 upon heating at 130 °C under reduced pressure produced a guest-free coordination polymer [Ni(dps2(NO32] (2b. Although the 2a and 2b guest-free coordination polymers have the same formula, they showed differences in the assembled structures of the one-dimensional chains. Exposure of 2b to EtOH vapor reproduced 1, while 2a did not convert to 1 in a similar reaction. Reaction of Ni(NO32·6H2O with dps in acetone provided [Ni(dps(NO32(H2O]·Me2CO (4 with no channel structure. When MeOH or acetone was used as a reaction solvent, the [Ni(dps2(NO32]·(guest molecule type coordination polymer ,which was observed in 1, was not formed. Nevertheless, the reaction of Ni(NO32·6H2O with dps in MeOH/acetone mixed solution produced [Ni(dps2(NO32]·0.5(MeOH·acetone (5, which has an isostructural Ni-dps framework to 1.

  6. STRATEGIC MARKETING ALTERNATIVES AT AGRO-TOURISM GUEST HOUSE LEVEL

    Full Text Available During the last years, tourists started to turn away from the mass tourism and consider the alternative one. Therefore, various forms of tourism were born, among which the rural tourism, to be regarded from two perspectives: it contributes to local and regional development and brings benefits to tourism by creating a new, higher quality holiday concept. This requires the participation of local authorities in the preparing of area development strategies, involving the inhabitants and local traders. By following up the dramatic condition of the Romanian tourism, the insufficient development of the rural tourism and the low involvement degree of the local authorities, we proposed an assessment and recommended strategic marketing alternatives for the improvement of the current condition of the agro tourism guest houses.

    Dölle, Sarah; Park, Ji Hyun; Schymura, Stefan; Jo, Hyeran; Scalia, Giusy; Lagerwall, Jan P. F.

    In this chapter we discuss the benefits, peculiarities and main challenges related to nanoparticle templating in lyotropic liquid crystals. We first give a brief bird's-eye view of the field, discussing different nanoparticles as well as different lyotropic hosts that have been explored, but then quickly focus on the dispersion of carbon nanotubes in surfactant-based lyotropic nematic phases. We discuss in some detail how the transfer of orientational order from liquid crystal host to nanoparticle guest can be verified and which degree of ordering can be expected, as well as the importance of choosing the right surfactant and its concentration for the stability of the nanoparticle suspension. We introduce a method for dispersing nanoparticles with an absolute minimum of stabilizing surfactant, based on dispersion below the Krafft temperature, and we discuss the peculiar phenomenon of filament formation in lyotropic nematic phases with a sufficient concentration of well-dispersed carbon nanotubes. Finally, we describe how the total surfactant concentration in micellar nematics can be greatly reduced by combining cat- and anionic surfactants, and we discuss how nanotubes can help in inducing the liquid crystal phase close to the isotropic-nematic boundary.

    Thermal effects of inclusion processes of {alpha}-, {beta}-, {gamma}- and M{beta}-cyclodextrin with resveratrol (RES) in aqueous solutions were determined by isothermal titration calorimetry (ITC) with nanowatt sensitivity at the temperature of 298.15 K. Standard enthalpy changes, stoichiometry and equilibrium constants of the inclusion complexes were derived from the direct calorimetric data utilizing nonlinear simulation. The thermodynamic parameters were discussed in the light of weak interactions between the host and the guest molecules combining with UV spectral message. The results indicate that all of the complexes formed in the aqueous solutions are in 1:1 stoichiometry. The binding processes of {alpha}-, {beta}- and M{beta}-cyclodextrin with the guest are mainly driven by enthalpy, while that of {gamma}-cyclodextrin with the drug is driven by both enthalpy and entropy.

  11. Caged Molecular Glues as Photoactivatable Tags for Nuclear Translocation of Guests in Living Cells.

    We developed dendritic caged molecular glues ( Caged Glue-R) as tags for nucleus-targeted drug delivery, whose multiple guanidinium ion (Gu + ) pendants are protected by an anionic photocleavable unit (butyrate-substituted nitroveratryloxycarbonyl; BA NVOC). Negatively charged Caged Glue-R hardly binds to anionic biomolecules because of their electrostatic repulsion. However, upon exposure of Caged Glue-R to UV light or near-infrared (NIR) light, the BA NVOC groups of Caged Glue-R are rapidly detached to yield an uncaged molecular glue ( Uncaged Glue-R) that carries multiple Gu + pendants. Because Gu + forms a salt bridge with PO 4 - , Uncaged Glue-R tightly adheres to anionic biomolecules such as DNA and phospholipids in cell membranes by a multivalent salt-bridge formation. When tagged with Caged Glue-R, guests can be taken up into living cells via endocytosis and hide in endosomes. However, when the Caged Glue-R tag is photochemically uncaged to form Uncaged Glue-R, the guests escape from the endosome and migrate into the cytoplasm followed by the cell nucleus. We demonstrated that quantum dots (QDs) tagged with Caged Glue-R can be delivered efficiently to cell nuclei eventually by irradiation with light.

  18. What is and what is not a book: its materiality and editorial processes

    2013-03-01

    Full Text Available In this paper, we propose a discussion on e-books as a marked product, not just as a discursive framework or because its format, but also by an editorial process at least partially distinct from the printed book. Moreover, the concepts of material formats and reading practices help to deal with aspects of reading modes that are in evidence when books and e-books are referred. Devices for reading and reader's experience seem to have a key role in proposing a process for publishing electronic books. It is argued here that, since the editorial processes of the printed book and eBook are partly differentiated, besides offering different size and experience, the book could be considered simply as a metaphor of the new editorial product produced to be read in new devices. If the entered text genres are the same, the objects are not, and thus it can be said that those genres that are published in a book not necessarily characterize it, but other elements of its characterization. The arguments posed here are based on discussions on editing processes (Eco and Carriere, 2010; Darnton, 2010; Chartier,1998, 2000, 2002; and Procopio, 2010. The concepts of formats are based on Távora (2008.

    1995-02-01

    This editorial introduces a journal devoted to examination of the implications of cultural issues on gender and development work. The secondary status of women is one of the few universals in the world, with biology used as an excuse (yet the only constraints placed upon a woman by biology are when she is pregnant or breast feeding). Constraints differ among societies, and cultural practices which appeal to tradition reinforce the power of men. Patriarchal societies foster the notion of an ideal woman to insure the paternity of children and preserve the families. Because women have primary responsibility for children, they are also perceived as the guardians of the very culture which reduces their status. Rape and domestic violence are used to enforce women's conformity to a traditional role. Violence against women is also used as a weapon of warfare while religious fundamentalists manipulate religious texts to insure women's subordination. Participation in development efforts, however, can allow women to question their marginalization and to become positive role models for other women. The arts and the media can also be used to challenge the status quo. The views of women from southern nations have also been marginalized by the north, and people with formal education wield more power than those with experience but no qualifications. Multicultural ideals require development agencies to listen to historically ignored voices, to make a longterm commitment to cultural change, and to employ local people. Charges of cultural imperialism can be refuted if the aspirations of southern women are included on the development agenda.
