Published: May 2019

Hollandite is a ceramic
used for the confinement of cesium. In this study, we synthesized a hollandite
of chemical formula: K0.28Ba0.76Ti7.10Cu0.9O16,
where K simulates cesium. This new formulation of a copper-containing hollandite
was synthesized by a double calcination; the first one at 950°C during 18 h,
and the second one at 1000°C during 6 h. The mineral was identified by X-ray
diffraction. Various leaching tests are employed in order to assess the
chemical durability of this mineral. The static test MCC1 gave elemental leaching
rates of: 7.097 10-5 g cm-2 d-1 for Cu, 5.592
10-7 g cm-2 d-1 for Ti and 4.630 10-6
g cm-2 d-1 for Ba, after 42 days. This corresponds to
dissolved elements percentages of: 5.7% Cu, 0.0007% Ti and 0.2% Ba. The
equivalent amount of dissolved K is 0.0029%. A static test in the presence of a
clay barrier, gave the best leaching rates (at 42nd day, NR<3.704
10-7 g cm-2 d-1 of Cu, and <1.11 10-9
g cm-2 d-1 of Ti and <3.67 10-9 g cm-2
d-1 of Ba). This corresponds to 0.030% of Cu, 10-6 % of
Ti and 0.002 % of Ba, and about 0.002% of K. In MCC5 dynamic test, the leaching
rates of Cu, Ti and Ba reached 2 10-6, 1,468 10-7, and
1.084 10-5 g cm-2 d-1, respectively,
corresponding to 0.028% Cu, 0.0003% Ti, and 0.082% Ba, after seven days. The
estimated K leaching rate is 3.613 10-6 g cm-2 d-1,
ie 0.082% K dissolved in the leachate. There is no passivation layer formation.
The MCC5 test is considered as a dissolution test.
Sexual Harassment and Violence at Events and Festivals: A Student Perspective
Authors: Pernecky Tomas , Abdat Safira , Brostroem Beatrice , Mikaere Danielle , Paovale Hazen
Published: May 2019

Sexual harassment at large events is a pressing concern that affects people around the world. Although the topic has been addressed in hospitality and tourism, research on sexual harassment in the fields of event management and event studies is almost nonexistent and has thus far failed
to provide an adequate, knowledge-based response. This article seeks to address the impoverished treatment of the problem by drawing on a student-centered project. In addition to identifying the key issues around sexual harassment facing the events industry, the article highlights the importance
of early career female scholarship—making a case for curriculum development that leads to engagement with contemporary societal problems and critical citizenship.
Arts Festival Offerings: What Do Market Segments Prefer? Evidence from a South African National Arts Festival
Authors: Kruger Martinette
Published: May 2019

This research assesses visitors' push and pull motives for attending the Innibos National Arts Festival in South Africa. The results show that segmenting visitors on the basis of their motives is a useful market segmentation tool, as it produces a clear and direct profile and understanding
of different types of visitors and their preferences as regards festival offerings. The study is the first to identify the stalls visitors preferred at the festival. It shows that, when managed correctly, stalls selling arts and crafts, food and drinks, and so on, enhance the overall festival
experience. The study consequently proposes a typology of arts festival visitors to Innibos (Curious wanderers, Loyalists, and Socialites) that may be applicable to other arts festival markets. The results of this research can be used by Innibos and other festivals to
better cater to the needs of the market.
Events are Bound to Happen, Spank You Very Much: The Importance of Munch Events in the BDSM Community
Authors: Webster Craig , Ivanov Stanislav
Published: May 2019

The kinkster/BDSM community is a sexual minority that largely operates underground. Although not linked directly with the sexual practices of the community, the prevailing social institution of the subculture is the munch, social gatherings in which no "kink" activities take place.
In this research, we analyze data from two international surveys, one of munch organizers and one of munch participants. The findings show the lifestyle and demographic variables that are linked with placing importance on the institution of the munch. One major finding from the research is
that munch participants are most strongly motivated with a desire to socialize, rather than looking for partners for sexual experiences, although these two motivations are not mutually exclusive. In addition, we see that for both organizers and participants in munches, the more years in the
lifestyle, the less importance organizers and participants place on the munch for their involvement in the lifestyle.
Together Alone: An Exploration of the Virtual Event Experience
Authors: Wreford Olivia , Williams Nigel L. , Ferdinand Nicole
Published: May 2019

After 50 years in development, virtual reality (VR) has now become commercially available to consumers. The events industry has started to adopt this transformational technology, by implementing it into live events or using it as an alternative method for providing event experiences.
However, little research attempts to compare real to virtual event experiences to understand perceived user benefits and drawbacks. Using Uses and Gratifications (UG) Theory, this study aims to understand the possible user benefits provided from virtual event experiences. A process was designed
that incorporated the viewing of a VR experience that was similar to an event previously attended by respondents. They were then interviewed and performed a product reaction card exercise to compare their experiences. Analysis of the data suggests that current 360 VR technology can be used
to extend the experiencescape but not replace live events. Respondents indicate that VR provides emotional gratifications that may build positive associations with event organizations and brands. However, VR in its current form does not provide the social and sensory gratifications of live
events. VR can therefore be used to deepen relationships with existing participants or encourage future participation at events.
What Preevent Motives Determine the Decision to Volunteer at a Sporting Event: How Can Herzberg's Two-Factor Theory Help?
Authors: Lamb David , Ogle Alfred
Published: May 2019

This article examines the preevent motivations of volunteers recruited from the local community for a sporting event. Using empirical data and Herzberg's two-factor theory as a framework, satisfaction attributes impacting upon volunteer expectations prior to the actual event were investigated.
The researchers sought to determine why volunteers involved themselves with the event, and what key factors underpinned their decision-making process. A paper-based survey administered to registered volunteers probed volunteers' preevent motives. The emergent themes from analysis of the respondents'
(N = 97) feedback ranged from altruism (helping others) to self-interest (a complimentary round of golf). The predominant theme was the respondents' "love of the game," which encompassed the subthemes of self-interest and perceived personal benefits. Also, community benefits such as
the building of community identity, social recognition, and pride were deemed as important due to the affiliative nature of the local golfing fraternity, the primary distinguishing factor for volunteering at the material event. The study found that hygiene factors were crucial in forming the
foundations for a positive volunteer experience, whereas satisfaction was closely linked to the presence of motivational attributes of the event. The identification of hygiene and satisfaction factors can be invaluable input for event organizer's strategy to recruit volunteers. Furthermore,
by putting into place hygiene factors volunteers are less likely to experience dissatisfaction and by targeting the primary motivators of their volunteers, the attention of prospective volunteers can be captured and then effectively converted into an interest in the event eventually leading
to making the commitment to participate. The effective engagement with volunteers can engender a positive experience, which increases the likelihood of repeat volunteering.
Crisis Management Communications For Popular Culture Events
Authors: Pappas Nikolaos
Published: May 2019

Based on the conceptualization of the existing literature, the aim of this article is to discuss the risk and crisis communication aspects in tourism with reference to popular culture events. It focuses on (1) the influence of potential crises in popular culture events on destination
image and branding, (2) the crisis marketing aspects that need to be considered from the event organizers and destination marketing organization (DMO) authorities, and (3) the communications' reaction of stakeholders in respective crises. From a theoretical perspective, its contribution deals
with the provision of an understanding in terms of marketing communications in popular culture events when facing crises. Managerially, this article contributes through the formulation of essential tools for crisis communications in the respective events, including both external and internal
marketing strategies.
Environmentally Sustainable Lifestyle Indicators of Travelers and Expectations for Green Festivals: The Case of Canada
Authors: Dodds Rachel , Walsh Philip R. , Koç Burcu
Published: May 2019

Festivals are emerging as one of the most attractive events in the tourism industry as their cultural and social wealth can contribute to the general promotion of a destination. Increased desire by communities to behave more responsibly has encouraged more sustainability-focused strategies
on the part of festival organizers and have stimulated other industry stakeholders towards such actions. Accordingly, understanding what ecological behaviors might contribute to encouraging festival attendance can be important to planning a festival. In this regard, the main purpose of this
research was to investigate real life environmentally sustainability tendencies of festivalgoers and their attitude towards attending environmentally sustainable festivals. Survey data were collected from 849 Canadian respondents who had attended a festival at least once in 2017. Our findings
illustrate that a positive attitude towards attending a green festival is more strongly predicted by the level of intrinsic voluntary environmental actions that reflect personal commitment than by more mechanistic environmental activities such as waste reduction and recycling.
Trends in Tourism-Related Academic Conferences: An Examination of Host Locations, Themes, Gender Representation, and Costs
Authors: Chen Shu-Hsiang , Tham Aaron
Published: May 2019

This article examines trends associated with tourism-related academic conferences scheduled between mid-2016 and end-2018. As a subset of a lucrative business events market, studies on academic conferences remain underinvestigated. Moreover, academic literature to date reveal that extant
studies are often fragmented—using one conference or through the perspective of a single stakeholder group. To address the paucity of literature related to academic conferences, this article uncovers trends within 360 tourism-related academic conferences through four aspects: Host locations,
themes, gender representation, and costs. The findings reveal that tourism-related academic conferences are mostly held within the continents of Asia and Europe, mirror academic and industry contemporary discourses, reflect the persistent gap in terms of gender representation, and present
increasing costs of attendance unequally skewed towards a few conferences. Timing of tourismrelated academic conferences are also largely scheduled towards the first half of the year. Further recommendations are made to organizers planning for future tourism-related academic conferences to
make these events more inclusive such as (1) deriving themes from industry inputs, (2) creating a balanced profile of male and female keynotes speaker, and (3) considering cost-efficient practices to create more sustainable academic conferences.
Walkability in the Historic City of Oaxaca, Mexico
Authors: Barrera-Fernández Daniel , Hernández-Escampa Marco
Published: May 2019

The renovation of traditional events to suit contemporary demands carries important benefits for the hosting cities, such as the increase in the number of visitors, and the differentiation of destinations and urban spaces that are apparently similar for potential tourists. However,
street events attract a considerable number of visitors that are concentrated in a very limited space for a short stay. Especially in historic cities with large number visitors, the so-called tourist-historic cities, events contribute to the commodification of public space, overcrowding, and
overuse of certain public spaces and heritage assets during a very short period. Thus, the walkability of this urban area plays a key role in visitors' satisfaction and experience. This article explores the perceptions of tourists in relation to walkability in the streets of the city center
of Oaxaca, Mexico, during the celebration of the Guelaguetza Festival. The city center of Oaxaca was included in UNESCO's World Heritage List and is one of the most visited urban destinations in Mexico, while the Guelaguetza is the most popular annual event in the city for national and international
visitors. A mixed methodology was developed based on direct observation of tourists walking along the streets of central Oaxaca and the application of a questionnaire. The questionnaire focused on personal aspects and external aspects that affect the desire to walk, such as safety, cleanliness,
traffic congestion, and pollution. The results showed relevant differences according to the visitor's background and allowed to suggest some urban improvements to increase visitors' satisfaction. Urban design to achieve a more walkable city is closely related to the success of street festivals
and should be included in the early stages of an event's design.
Making Sure They Have the Time of Their Lives: Identifying Cocreation Opportunities at the Dirty Dancing Festival
Authors: Benjamin Stefanie , Knollenberg Whitney , Chen Rachel
Published: May 2019

Film-induced festivals are becoming more popular, generated through accessibility of streaming platforms and acceptance for popular culture fandom. This is different than any general film festival, because there is a sense of community and desire for recreation among film-induced festival
attendees, who are seeking a very specific feel and experience. This excitement can also spill over into the surrounding community, thus sparking interest with festival organizers and community hospitality and retail business owners. Knowing what experiences film-induced festival attendees
are seeking can potentially increase visitation, facilitate positive word of mouth, and promote return intentions. This study explored The 2017 Dirty Dancing Festival at Lake Lure, NC, USA where social media posts were collected to understand how attendees experienced the festival.
Informed by cocreation theory and a qualitative content analysis, seven themes related to the lived experiences of festival attendees were identified providing in-depth information on attendees' expectations of film-induced festivals. Their experiences related to recreating film scenes and
scouting film locations helped to contribute evidence for how festival organizers can maximize cocreation through film-induced festivals using social media posts.
Escaping from the Event? Residents' Perception of Christmas Markets in Northern Italy
Authors: Marcher Anja , Erschbamer Greta , Pechlaner Harald
Published: May 2019

Christmas markets as annual cultural events are constantly changing and have become a mass phenomenon of our day. Even though they represent a promising strategy to extend low seasons in tourism, the growing number of visitors can negatively impact residents' perceptions of the event
and its authenticity. The central purpose of this study is to gain a new perspective on Christmas markets as cultural events focusing on residents by considering them as important actors within a tourism destination. Qualitative interviews with residents of Meran, a Christmas market destination
in Northern Italy, explored their meaning for the locals and the impact of increasing numbers of visitors on their loyalty to the event, by implementing the GABEK qualitative research strategy. The results give insights into central aspects of the events' authenticity, show a shift to less
commercial settings in rural areas, and highlight some negative impacts.
Priming Host City Physical Legacy Plans: The Bidding Chronicles of Brazil's Derailed Sporting Event Infrastructure Projects
Authors: Kirby Seth I. , Crabb Lauren A. H.
Published: May 2019

This article presents a case study of the 2014 FIFA World Cup in Brazil and the 2016 Olympic Games in Rio de Janeiro to explore infrastructure development and physical legacies connected to the planning, bidding, and staging of mega-sporting events. Primary data were collected in Cuiabá
in two phases during the 2014 World Cup and after the event in 2015. This entailed participant observation, structured observation, document analysis, and 15 semistructured interviews with the local population, as well as current and former government and stadium employees. Following the Rio
2016 Olympic Games primary data were collected from Porto Maravilha, Rio de Janeiro. In January 2018, 15 semistructured interviews were undertaken with tour operators and cultural businesses. Significant evidence indicates the ineffectiveness of urban and rural infrastructure development and
facility improvements, delays and cancellations in infrastructure programs, stadiums and venues overshooting their original costs and budgetary requirements, and controversial targeted transport interventions. Practical managerial recommendations and strategies are offered to aid the implementation,
management, and maintenance of host city infrastructure during the planning, bidding, hosting, and post-sporting event phases.
Understanding Festival-Goers and Their Experience at UK Music Festivals
Authors: Brown Alyssa Eve , Sharpley Richard
Published: May 2019

This article explores the influence of sociodemographic characteristics in determining the perceived importance of attributes of the UK music festival experience to festival-goers. Quantitative data were collected through an online survey using a cluster, snowball sampling technique
and 586 respondents completed the survey. Exploratory Factor Analysis (EFA) was used to identify factors of the festival experience, whereas linear regression and structural equation modeling (SEM) revealed the relationship between the sociodemographic characteristics of festival-goers and
the resulting experience constructs against the overall evaluated experience. From eight major factors, seven hypotheses were identified. The results revealed the most important factors to the overall experience to be entertainment, added value, and music, whereas the remaining factors did
not have a direct impact. Conversely, the sociodemographic characteristics contributing to the dependent constructs were primarily age and gender, followed by education and marital status. The location where festival-goers grew up and their employment status had minimal impact. The practical
implications of this study provide the opportunity for festival organizers to direct their strategic management efforts towards the elements of the festival experience that are most important to their targeted or typical festival-goers. This article also addresses a notable gap in the literature
by evaluating the importance of specific experience attributes in the context of popular UK music festivals. Moreover, it examines the relationship between sociodemographic characteristics of festival-goers and the importance of experience attributes to the overall UK music festival experience.
The Stakeholder Sandwich: A New Stakeholder Analysis Model for Events and Festivals
Authors: Wallace Kevin , Michopoulou Eleni
Published: May 2019

The significance of stakeholders in the festival and events sector is demonstrated in the literature and is a growing area of interest. The application of conventional stakeholder theory to this sector has proved to be problematic and new models developed as alternatives. Since the
1980s a number of matrices and models have been established to identify and categorize stakeholders, but limitations have been exposed in the context of festival and events research. This study set out to explore the use of established stakeholder models for their usefulness and effectiveness
in the sector, consider alternative models and to examine empirically a proposed alternative. To do so, a multiphased qualitative methodology was used. Results indicated that none of the conventional or proposed sector-specific models were in common usage by sector professionals but did confirm
that Ed Freeman's founding stakeholder definition of 1984 continues to be valid and hold true. The framework for a new conceptual test model was developed and then refined to produce the Stakeholder Sandwich Model for testing on a live event. This model proved to be effective in identifying
and mapping a wide range of stakeholders with flexibility and fluidity, overcoming the limitations of both established conventional models and more recent sector-specific typographies. This model has significant potential for application in the festival and events sector, with implications
for both researchers and event practitioners.
Challenges in Managing Peripheral Workers Within Diverse Environments
Authors: Michopoulou Eleni , Melpignano Claudia
Published: May 2019

This article explores the HR issues that tour operators experience in the planning, coordination, and management of tours revolving around cycling events. It does so by using a tour operator based in the UK as a case study and by deploying a qualitative ethnographic approach. This methodology was deemed as the most fitting to enable an in-depth and rich analysis of the issues that characterize the complex management of core (office-based employees) and peripheral workers (tour guides on the event site). Not only do the different operations, time frames, environments, and activities within which the employees operate result in the company's workforce division into two distinctive groups, but they also determine low levels of professional satisfaction and motivation among the tour guides. Investigating the stances held by the company's employees in relation to the difficulties encountered in the workplace is necessary to develop a strategy that allows for retaining peripheral workers, for creating synergy between the two different teams, and consequently for ensuring the achievement of the organization's goals and objectives. The findings highlight how the adoption of HR practices that aim at enhancing the company's internal marketing would entail an optimistic shift in the tour guides' perception of their position within the company, resulting in improved product delivery and reduced absenteeism, burnout, and turnover challenges.
Talent Management and Retention in Events Companies: Evidence from Four Countries
Authors: Marinakou Evangelia
Published: May 2019

A variety of social, economic, and political factors (such as enhanced labor mobility, refugees' phenomenon, and immigration) have led to a volatile business environment and a changing labor profile in the events industry. Against this highly competitive and volatile background, events
management businesses must deal with the challenging task of effectively attracting, managing, and retaining their talented employees contributing to their competitive advantage. This study aims at exploring talent management and retention strategies in the events industry. Using a qualitative
approach, data were collected with semistructured interviews from four countries: the UK, the US, Greece, and Australia. Participants in this study recognized the strategic value of effective talent management. The findings suggest that the main strategies to retain talent in the events sector
in the Western context include a friendly and open access culture, teamwork, mentoring, leadership, compensation, succession planning, and training and development as the key strategies to retain talent. More importantly, events companies should focus on staff engagement; highly engaged employees
are more aligned with the company's vision and culture. This enables managers reduce staff turnover and enhance job satisfaction.
The Path to Adoption and Advocacy: Exploring Dimensions Of Brand Experience and Engagement at Trade Shows
Authors: Kennett-Hensel Pamela A. , Kemp Elyria , Williams Kim , Borders Aberdeen Leila
Published: May 2019

Trade shows are typically second only to personal selling in business-to-business promotional expenditures. As a result, trade show attendees are often inundated with product offerings by competing firms. In order to successfully vie for attention, firms must find ways to engage attendees
and potential consumers. A key component of engaging with a brand is considering how consumers experience the brand. This research examines the dynamics which enhance brand engagement by understanding the factors which contribute to the brand experience of attendees at trade shows. Both qualitative
and quantitative data collected from actual trade show attendees highlight the dimensions of brand experience and indicate that a positive brand experience is related to product adoption, which in turn is related to advocacy for the brand. Considering how to shape the brand experience of consumers
in trade show settings enables a brand to successfully compete for attention with other offerings as well as helps to foster engagement levels that eventually lead to positive outcomes for the firm. Implications for considering brand experience as a key element of trade show marketing strategy
are discussed.
Zero Hours Contracts and Their Perceived Impact On Job Motivation of Event Catering Staff
Authors: Filimonau Viachaslau , Corradini Sara
Published: May 2019

Catering is a cornerstone of events. Motivating catering staff, who can be either permanent or "hourly paid" employees, represents an important managerial challenge, especially in the UK, where controversial zero hours contracts (ZHCs) prevail within the events industry. This article reports a representative case study of a London-based event catering company that relies upon ZHCs. In pursuit of corporate social responsibility (CSR) goals, directed at enhancing the well-being of employees and improving corporate image, the company considers replacing ZHCs with alternative contracts, but wishes to examine the potential impact of this intervention first. To aid in decision making, 18 indepth, semistructured interviews are conducted with company's managers and employees to examine the drivers of staff motivation and the perceived effect of ZHCs. The study finds that interpersonal relationships, remuneration rates, and perceived fairness of managerial treatment drive staff motivation in event catering. The major positive (flexibility and no mutual obligation) and negative (job insecurity and instable income) implications of ZHCs are well understood by employees. The internal (personal finances, family status, and individual lifestyles) and environmental (current job market situation and managerial abilities) circumstances determine the level of preparedness and the degree of willingness of event catering staff to accept ZHCs. Implications for policy making, professional practice, and future research are discussed.
Multicomponent reactions (MCRs): a useful access to the synthesis of benzo-fused γ-lactams
Authors: de Marigorta Edorta Martínez , Santos Jesús M de Los , Ochoa de Retana Ana M , Vicario Javier , Palacios Francisco
Published: May 2019

Benzo-fused γ-lactam rings such as isoindolin-2-ones and 2-oxindoles are part of the structure of many pharmaceutically active molecules. They can be often synthesized by means of multicomponent approaches and recent contributions in this field are summarized in this review. Clear advantages of these methods include the efficiency in saving raw materials and working time. However, there is still a need of new catalytic systems to allow the enantioselective preparation of these heterocycles by multicomponent reactions.
Notes on Justicia sect. Monechma (Acanthaceae) in Angola, including two new species
Authors: Darbyshire I. , Goyder D.J.
Published: May 2019

Two new species of Justicia sect. Monechma, Justicia cubangensis and J. eriniae, are described from Angola. Their affinities are reviewed, together with a discussion on the correct generic name to apply to these species. A conspectus of Justicia sect.
Monechma 'Group I' in Angola is presented, including a key to the species and notes on habitat and distribution for each taxon. Two new combinations and one new name are provided for species for which there was no previous name available in Justicia, and lectotypes are proposed
for four names. Twelve species are recognised in this group in total, eight of which are currently believed to be endemic to Angola. Justicia subsessilis is recorded in Angola for the first time, and J. laeta is placed in sect. Monechma, having previously been tentatively
referred to sect. Tyloglossa. Monechma carrissoi is considered to be conspecific with J. virgultorum and so is synonymised here. In addition, the botanical importance of the type locality of J. cubangensis, the Cuchi River gorge of the Cubango drainage, is highlighted
and two further new provincial records for Cuando Cubango are noted from this site: Eriocaulon angustibracteum (Eriocaulaceae) and Crepidorhopalon schweinfurthii (Linderniaceae).
Re-evaluation of Mycoleptodiscus species and morphologically similar fungi

Published: May 2019

Mycoleptodiscus includes plant pathogens, animal opportunists, saprobic and endophytic fungi. The present study presents the first molecular phylogeny and revision of the genus based on four loci, including ITS, LSU, rpb2, and tef1. An extensive collection of Mycoleptodiscus
cultures, including ex-type strains from the CBS, IMI, MUCL, BRIP, clinical isolates from the USA, and fresh isolates from Brazil and Spain, was studied morphologically and phylogenetically to resolve their taxonomy. The study showed that Mycoleptodiscus sensu lato is polyphyletic.
Phylogenetic analysis places Mycoleptodiscus in Muyocopronales (Dothideomycetes), together with Arxiella, Leptodiscella, Muyocopron, Neocochlearomyces, and Paramycoleptodiscus. Mycoleptodiscus terrestris, the type species, and
M. sphaericus are reduced to synonyms, and one new species is introduced, M. suttonii. Mycoleptodiscus atromaculans, M. coloratus, M. freycinetiae, M. geniculatus, M. indicus, M. lateralis (including M. unilateralis and M. variabilis
as its synonyms) and M. taiwanensis belong to Muyocopron (Muyocopronales, Dothideomycetes), and M. affinis, and M. lunatus to Omnidemptus (Magnaporthales, Sordariomycetes). Based on phylogenetic analyses we propose Muyocopron
alcornii sp. nov., a fungus associated with leaf spots on Epidendrum sp. (Orchidaceae) in Australia, Muyocopron zamiae sp. nov. associated with leaf spots on Zamia (Zamiaceae) in the USA, and Omnidemptus graminis sp. nov. isolated from a grass

We present Karl G. Jansky Very Large Array observations of the CO (2−1) line emission toward three far-infrared luminous quasars at z ∼ 6: SDSS J231038.88+185519.7 and SDSS J012958.51−003539.7 with ∼0.″6 resolution and SDSS J205406.42−000514.8 with ∼2.″1 resolution. All three sources are detected in the CO (2−1) line emission—one source is marginally resolved, and the other two appear as point sources. Measurements of the CO (2−1) line emission allow us to calculate the molecular gas mass even without a CO excitation model. The inferred molecular gas masses are (0.8–4.3) × 1010
M
⊙. The widths and redshifts derived from the CO (2−1) line are consistent with previous CO (6−5) and [C ii] measurements. We also report continuum measurements using Herschel for SDSS J231038.88+185519.7 and SDSS J012958.51−003539.7, and for SDSS J231038.88+185519.7 data obtained at ∼140 and ∼300 GHz using the Atacama Large Millimeter/submillimeter Array. In the case of SDSS J231038.88+185519.7, we present a detailed analysis of the spectral energy distribution and derive the dust temperature (∼40 K), the dust mass (∼109
M
⊙), the far-infrared luminosity (8–1000 μm; ∼1013
L
⊙), and the star formation rate (2400–2700 M
⊙ yr−1). Finally, an analysis of the photodissociation regions associated with the three high-redshift quasars indicates that the interstellar medium in these sources has similar properties to local starburst galaxies.

To place meaningful constraints on Big Bang Nucleosynthesis models, the primordial helium abundance determination is crucial. Low-metallicity H ii regions have been used to estimate it because their statistical uncertainties are relatively small. We present a new determination of the primordial helium abundance, based on long-slit spectra of the H ii region NGC 346 in the small Magellanic cloud. We obtained spectra using three 409″ × 0.51″ slits divided into 97 subsets. They cover the range λλ3600–7400 of the electromagnetic spectrum. We used PyNeb and standard reduction procedures to determine the physical conditions and chemical composition. We found that for NGC 346 X = 0.7465, Y = 0.2505, and Z = 0.0030. By assuming ΔY/ΔO = 3.3 ± 0.7 we found that the primordial helium abundance is Y
P = 0.2451 ± 0.0026 (1σ). Our Y
P value is in agreement with the value of neutrino families, N

ν
, and with the neutron half-life time, τ

We conduct a search for periodic emission in the very high-energy (VHE) gamma-ray band (E > 100 GeV) from a total of 13 pulsars in an archival VERITAS data set with a total exposure of over 450 hr. The set of pulsars includes many of the brightest young gamma-ray pulsars visible in the Northern Hemisphere. The data analysis resulted in nondetections of pulsed VHE gamma-rays from each pulsar. Upper limits on a potential VHE gamma-ray flux are derived at the 95% confidence level above three energy thresholds using two methods. These are the first such searches for pulsed VHE emission from each of the pulsars, and the obtained limits constrain a possible flux component manifesting at VHEs as is seen for the Crab pulsar.
Turning Gravitationally Lensed Supernovae into Cosmological Probes
Authors: Pierel J. D. R. , Rodney S.
Published: May 2019

Recently, there have been two landmark discoveries of gravitationally lensed supernovae: the first multiply imaged SN, “Refsdal”, and the first Type Ia SN resolved into multiple images, SN iPTF16geu. Fitting the multiple light curves of such objects can deliver measurements of the lensing time delays, which are the difference in arrival times for the separate images. These measurements provide precise tests of lens models or constraints on the Hubble constant and other cosmological parameters that are independent of the local distance ladder. Over the next decade, accurate time delay measurements will be needed for the tens to hundreds of lensed SNe to be found by wide-field time-domain surveys such as LSST and WFIRST. We have developed an open-source software package for simulations and time delay measurements of multiply imaged SNe, including an improved characterization of the uncertainty caused by microlensing. Using this package, we describe simulations that suggest that a before-peak detection of the leading image enables a more accurate and precise time delay measurement (by ∼1 and ∼2 days, respectively), when compared to an after-peak detection. We also conclude that fitting the effects of microlensing without an accurate prior often leads to biases in the time delay measurement and over-fitting to the data, but that employing a Gaussian Process Regression technique is sufficient for determining the uncertainty due to microlensing.
An unknown collection of lizards from Afghanistan

Afghanistan is a herpetologically understudied country with few published papers since the end of “Afghanistan’s Golden Age” from the 1930s to the 1970s. Although a detailed checklist of the herpetofauna of the country, based on exploration of herpetodiversity using biodiversity archives, has been published recently, there still exist additional historical data that have not been considered. This is the case for a so far unknown collection of lizards from Afghanistan deposited in the herpetological collection of the Institute for Biological Research “Siniša Stanković at the University of Belgrade, Belgrade, Serbia. The material comes from field research conducted in 1972 and contains 27 specimens in seven lizard genera representing four families (Agamidae, Gekkonidae, Lacertidae, Scincidae). This historical collection was examined and basic morphometric data, field data, and photographs are provided, comparing the distributional data with published datasets. Updated species distribution maps reveal new locality or province records and an important range extension for Eurylepis taeniolata Blyth, 1854 which represents the northernmost record for this species in Afghanistan. In addition, one further distribution record for the Bufotes viridis (Laurenti, 1768) complex from the same research trip is noted.

En s’appuyant sur des récits rétrospectifs recueillis auprès de jeunes issus de familles nombreuses et de leurs parents, l’article montre comment la socialisation temporelle des enfants au sein de leur famille peut ou non contribuer à l’acquisition de dispositions ajustées aux attentes de l’école. Il fait ressortir deux types de socialisation familiale socialement différenciés. En regardant leurs parents agir et en agissant eux-mêmes, les enfants des familles de classes moyennes et supérieures qui ont participé à notre enquête apprennent à planifier et à anticiper les activités comme à rationaliser l’usage de leur temps. En étant soumis à des règles explicites et des sanctions prévisibles, différées et durables, ils s’habituent en outre à revenir sur leurs actions passées et à anticiper l’avenir. À l’inverse, au sein de notre population, les enfants des familles de milieux populaires se familiarisent avec un rapport plus imprévisible et immédiat au temps. Le fait que les limites, notamment temporelles, soient davantage portées par les personnes qui les entourent que par des règles ou des dispositifs objectivés, et soient, plus que dans le premier groupe, dépendantes du contexte dans lequel les activités enfantines se déploient, est propre à engendrer chez eux une inclination à attendre que ces limites se manifestent de l’extérieur plutôt qu’à les anticiper et à réguler d’eux-mêmes leur comportement en prévision.

Cet article analyse les inégalités culturelles en matière de visites de musées d’art sous l’angle des rapports au temps. Il montre l’importance de la maîtrise du temps dans la production de la compétence artistique et d’un rapport légitime à l’art. Pour cela, l’article s’appuie sur les données issues d’une thèse combinant observation ethnographique d’une salle du musée des beaux-arts de Lyon et étude biographique de visiteurs occasionnels et réguliers de musées d’art. La population étudiée est composée de membres des classes supérieures et des fractions culturelles des classes moyennes. L’enquête permet de saisir deux dimensions étroitement articulées des rapports au temps : la planification (l’agenda des visites dans le temps long) et la sélectivité (l’organisation d’une visite dans le temps court). Elle met en évidence deux pôles des rapports au temps de visite : du côté des visiteurs à la bonne volonté culturelle, des visites rares, longues, et extensives ; du côté des visiteurs à forte compétence artistique, des visites fréquentes, plus courtes, et intensives, affranchies de la linéarité du parcours proposé par l’institution muséale. Les données permettent de situer la construction de ces dispositions temporelles durant la socialisation primaire. Ce faisant, l’article montre l’importance de la construction de routines, et donc de la maîtrise du temps, dans la différenciation sociale des rapports à l’art.
