Theoretical Studies on the Role of Guest in α-CL-20/Guest Crystals

The contradiction between energy and safety of explosives is better balanced by the host–guest inclusion strategy. To deeply analyze the role of small guest molecules in the host–guest system, we first investigated the intermolecular contacts of host and guest molecules through Hirshfeld surfaces, 2-D fingerprint plots and electrostatic interaction energy. We then examined the strength and nature of the intermolecular interactions between CL-20 and various small molecules in detail, using state-of-the-art quantum chemistry calculations and elaborate wavefunction analyses. Finally, we studied the effect of the small molecules on the properties of CL-20, using density functional theory (DFT). The results showed that the spatial arrangement of host and guest molecules and the interaction between host and guest molecules, such as repulsion or attraction, may depend on the properties of the guest molecules, such as polarity, oxidation, hydrogen content, etc. The insertion of H2O2, H2O, N2O, and CO2 had significant influence on the electrostatic potential (ESP), van der Waals (vdW) potential and chemical bonding of CL-20. The intermolecular interactions, electric density and crystal orbital Hamilton population (COHP) clarified and quantified the stabilization effect of different small molecules on CL-20. The insertion of the guest molecules improved the stability of CL-20 to different extents, of which H2O2 worked best.

게스트의 에어비앤비 지속적 사용의도 형성을 위한 플랫폼과 호스트에 대한 신뢰 및 애착 전이의 영향 연구

As the accommodation sharing industry grows, the role of guests and hosts participating in transactions with the Airbnb platform is also increasing. However, researches about the guests’ perception of Airbnb and the impact of host interaction with guest is lacking. Using the trust-transfer theory and attachment theory, this study examined how the interaction of host with guest make impact on the intention of guest's continuous use of Airbnb. We conducted a survey with 228 guests who have used Airbnb. The hypotheses were tested using structural equation modelling. It was found that guest interaction with host had a positive effect on trust in Airbnb and trust in the host. Trust in Airbnb and trust in the host had a positive effect on Airbnb attachment and host attachment, respectively. Finally, Airbnb attachment and host attachment had a positive effect on continuance intention. Also, it was found that trust in Airbnb can be transferred to trust in the host, and host attachment was found to stimulate Airbnb attachment. This study identifies the trust and attachment formed by the interaction with guest, and the continuance intention. Theoretically, our study contributes to expand trust-transfer and attachment theory by applying the home-sharing economy. Practically, practitioners of platform businesses and accommodation sharing industry participants can refer to our empirical results.

Money or love - Why do people share properties on Airbnb?

To keep apartment sharing platforms running, enough people have to act as hosts and offer accommodations. While a lot of research exists on the role of guests, the motivations of Airbnb hosts to offer rooms or apartments still need clarification. In an experimental, randomized, preregistered 2 (room vs. apartment) x 2 (financial vs. social motivation)-between-subjects design (N = 359) the present vignette study investigates the motivations of potential Airbnb hosts. Findings show that people are more willing to offer their property when they are made aware of the financial benefits than when social benefits are made salient, even in the case of experienced hosts. People are more willing to offer separate apartments than rooms within the apartment they live in. Willingness to host depends upon interpersonal characteristics such as risk taking but not on trust in others. The probability of making offers increases when guests can be selected more freely.

Mediating role of guest’s attitude toward the impact of UGC benefits on purchase intention of restaurants; Extending social action and control theories

ABSTRACT The User-Generated Content (UGC) like videos, text, images, experience that has been uploaded by the earlier users of a product on an online platform plays an important role in sales of the restaurants. On this aspect, the current paper investigated the role of mediation in the impact of UGC benefits on Purchase Intention of Restaurants across the Kashmir division of Jammu and Kashmir, India, to determine whether a guest’s attitude acts as mediation in between UGC benefits and Purchase Intention of Restaurants or not. A survey instrument was administered to 400 tourists/guests who visited hotel restaurants, out of which a total of 330 responses was judged as usable. The data were analyzed using Structural Equation Modeling (SEM) and other descriptive techniques. Also, the different theories like Social Action Theory and Social Control Theory were validated, which proved the results of this study are consistent with these theories, i.e., SAT, and SCT. This study also highlights that there is an impact on guests’ attitude in the relationship of UGC benefits and Purchase Intention of restaurants.

Antecedents and consequences of tourists’ attachment in driving guests’ booking intention: a case of Airbnb, Malaysia

PurposeAirbnb has emerged as one of the most prominent examples of sharing economy platforms in the tourism industry. The growing popularity of Airbnb among tourists has boost revenue in the accommodation rental industry. Considering its significant impact on tourism industry growth, this paper aims to shed some light on guests’ booking intentions on Airbnb, Malaysia.Design/methodology/approachA web-based survey was designed to collect the data, which yielded 174 usable and valid responses. Structural equation modelling, partial least square technique was used to analyse the data.FindingsThe results confirmed that Airbnb’s reputation and guests’ unique experience expectation positively affect guests’ attachment to Airbnb, which, in turn, drives guest booking intention. However, price consciousness did not exert any effect on guests’ attachment to Airbnb.Practical implicationsThe findings of this study will equip Airbnb managers, accommodation platform owners and service providers in developing appropriate marketing plans and strategies to better understand the implications of both internal and external causes that may lead to guests’ intention to book their accommodations.Originality/valueThis research has its merits in adding value to the tourism literature by understanding the drivers of guests’ booking intentions on Airbnb. Furthermore, the study findings contribute to the existing literature by investigating few new linkages such as the role of guests’ attachment to Airbnb as a mediator between guests’ unique experience expectation, price consciousness, reputation and guests’ booking intention.

Determinants of employee eco-initiatives in Indian hotel industry

Results of a questionnaire survey completed by 402 respondents who were all employees of hotels that have adopted eco-friendly practices showed that eco-initiatives are significantly and positively correlated to conservatism, commitment to the cause of the environment, and monetary rewards and recognition; significantly and negatively correlated to self-transcendence and environmental training; and bear no significant relationship with environmental communication and self-enhancement. Future research should consider the role of guests in promoting employee eco-initiatives.

Peer-to-peer interactions: Perspectives of Airbnb guests and hosts

In peer-to-peer (P2P) accommodation settings such as Airbnb, social interactions between peers are distinctively different from those between guests and employees in conventional lodging establishments. This study focuses on a reciprocal aspect of social interactions in P2P accommodations and aims to: 1) explore how guests and hosts perceive online and face-to-face interactions between them and 2) investigate the association between P2P interactions and some outcome variables (encounter satisfaction, word-of-mouth intention, and continuous intention to use) based on the roles of guest and host. A total of 503 responses from an online research panel were analyzed. The results show that guests perceive overall interaction experiences more positively than do hosts. Moreover, guests and hosts place weight on different interaction factors that contribute to their satisfaction and behavioral intentions. This study sheds light on the reciprocal interactions between guests and hosts, providing important theoretical and practical implications for the P2P lodging experience.

Dans les yeux des autres par Geneviève Brisac

Reviews 189 d’une jeune fille qui pousse son frère à la vendetta.Vénérande tournera-t-elle“le regard loin des tombeaux, loin de l’orgueil borné et du sang inutile, loin de [s]es propres chimères” (217)? Premier roman de Marc Biancarelli rédigé en français, Orphelins de Dieu est un superbe texte au pouvoir d’évocation visuelle étonnant. Villanova University (PA) Étienne Achille Brisac, Geneviève. Dans les yeux des autres. Paris: L’Olivier, 2014. ISBN 978-2-87929861 -0. Pp. 306. 18,50 a. In her eleventh work for adults, Brisac describes a conflicted family from multiple narrative angles. Anna Jacob, an author whose sister Molly took her to court to have her last novel censored for indecency, faces writer’s block as she contemplates her lack of livelihood while staying at Molly’s house. Caught between the roles of guest and housekeeper, she revisits memories of her childhood with Molly interspersed with comments about her present situation, in which she has lost “Déborah Fox,” the nom de plume as well as persona that she had adopted previously as a successful novelist. Depending on the themes of her ideas, she records them in diversely-colored notebooks : blue for happy reminiscences,black for unhappy memories,and red for political ones. Skillful narrative play in Dans les yeux des autres imparts emotional richness to the story. The omniscient narrator directs the reader to be saddened by Anna’s professional and emotional impasse through statements such as: “Que fait Anna qui est restée seule?” and “Où est passé le temps de quand elle était Déborah Fox?” (43). This second rhetorical question provides a transition to first-person narration in which Anna’s feelings of isolation are made known:“Jamais je n’avais imaginé être pauvre et seule, jamais. Sans amant, ni mari, sans amis, sans argent”(43). Following her detailed lament, however, the third-person narrator summarizes concisely, even ironically, her situation:“Telle est la substance de sa plainte”(43), which draws the reader out of any strong sentimental involvement with the text. Not only did Déborah Fox possess the social ease that Anna lacks, the former kept Mélina, the protagonist’s eccentric mother, at a comfortable distance by knowing exactly what to say. Anna, on the other hand, bereft of her authorial persona, merely antagonizes Mélina. If third- to first-person narrative shifts serve to portray Anna’s character in detail, the accounts of Mélina’s, Molly’s, and her boyfriend Boris’s lives remain opaque, since they lack the ongoing, introspective element of Anna’s musings. They nevertheless interest the reader. For example, Anna’s admission of sibling rivalry during her childhood sheds light on Mélina’s favoritism toward her daughter Molly, the doctor. Likewise, through stories about Boris’s ex-wife and Molly’s medical patients, told by the third-person narrator, one glimpses facets of these characters’personalities: Boris’s insecurity and maladjustment to adult life, and Molly’s practiced coldness toward others, including her sister. Despite these figures’ unresolved problems, it is Anna’s very human plight that holds the reader’s attention. Her possible reconciliation with Molly, her renewed attempts at writing fiction, and her tentative efforts to re-embrace life on her own terms inspire one to savor every page of this compelling novel.

On the role of guests in enforcing the mechanism of action of gated baskets

We designed and prepared a spacious and gated basket of type 2 (V = 318 Å(3)) in ten synthetic steps. With the assistance of (1)H NMR spectroscopy, we found that the pyridine gates at the rim of 2 form a seam of N-H∙∙∙N hydrogen bonds, thereby adopting right- (P) and left-handed (M) helical arrangements. The recognition characteristics of the smaller basket 1 (V = 226 Å(3)) and the larger 2 for various solvents as guests were quantified by (1)H NMR spectroscopy in CD2Cl2 (61 Å(3)), CDCl3 (75 Å(3)), CFCl3 (81 Å(3)) and CCl4 (89 Å(3)); the apparent guest binding equilibria Ka were found to be inversely proportional to the affinity of bulk solvents KS for populating each host. The rate of the P/M racemization (krac, s(-1)) was, for both 1 and 2, studied in all four solvents using dynamic NMR spectroscopy. From these experiments, two isokinetic relationships (ΔS++P/M vs. ΔH++P/M) were identified with each one corresponding to a different mechanism of P/M racemization. A computational study (B3LYP/6-31+G**//PM6) of 1 and 2 in the gas phase indicates two competing racemization pathways: (a) RM1-2 describes a pivoting of a single gate followed by the rotation of the remaining two gates, while (b) RM3 depicts simultaneous (geared) rotation of all three gates. The racemization of the larger basket 2, in all four solvents (packing coefficient, PC = 0.19-0.28), conformed to one isokinetic relationship, which also coincided with the operation of the smaller basket 1 in CD2Cl2 (PC = 0.27). However, in CDCl3, CFCl3 and CCl4 (PC = 0.33-0.39), the mode of action of 1 appears to correlate with a different isokinetic relationship. Thus, we propose that the population of the basket's inner space (PC) determines the mechanism of P/M racemization. When PC < 0.3, the mechanism of operation is RM1-2, whereas, a greater packing, represented when PC > 0.3, enforces the geared RM3 mechanistic alternative.

Indication

Should the indications for therapies differ from one nation to the next? What are the reasons behind controversial therapeutic variations? What roles do cultural history and authoritarian conflict among clinicians play in the adoption of therapies? When I worked at a rural hospital in Kenya, a woman experiencing obstructed labor made me ponder many questions-but only after our emergency ended in the death of her newborn son. In recounting and learning from this episode, I listened to the disparate Kenyan voices of the patient, the hospital's director, the consultant obstetrician, and to the even more controversial voices of evidence-based medicine. In reflecting on this process, I have learned at least 3 lessons-about the transmissibility of arrogance, the role of guests in other countries, and the nature of science.

Comment on ‘Two roles of guest and crosslinked degree on hydrosoluble β-cyclodextrin polymer electrorheological fluids’ by Z. Gao and X. Zhao

Comments on the recent studies of electrorheological (ER) properties of hydrosoluble β-cyclodextrin polymer based ER fluids are given based on the analysis of their yield stress data as a function of applied electric field strengths. Using our previously reported universal yield stress equation and critical electric field strengths deduced, it is found that we can collapse their data into a single curve.

Occupational patterns of people with dementia in residential care: An ethnographic study

This paper describes an ethnographic study that sought to gain knowledge of the occupational patterns of persons with dementia in a care home and how the residents perceived the group activities in which they participated. The residents’ ages ranged from 82 to 92 years. They were seven women and one man. Both participant observation and interviews were used to collect data. Data analysis resulted in an ethnographic story organised around two key themes: (1) the occupational patterns of the residents, and (2) the residents’ perceptions of the activities offered. In this story residents appeared passive, playing the role of guests in the care home. Residents were dependent on staff to engage in daily occupations. Interviews revealed that residents perceived participation in activities as important to their mental and physical health and an advantage of living in the care home.

Two roles of guest and crosslinked degree on hydrosoluble $beta;-cyclodextrin polymer electrorheological fluids

As a potential candidate for the development of well-controlled electrorheological (ER) materials, five hydrosoluble β-cyclodextrin polymer (2–6)/3-hydroxy-2-naphthoic acid particles (2′–6′) were synthesized. Fluorescence analysis conformed that all the polymers can form 1:1 type supramolecular complex with the guest. The ER properties of suspensions of these particles in silicon oil have been investigated under DC electric field. The yield stress of the typical supramolecular complex (5′) ER fluid was 9.23 kPa at 4 kV/mm. It was much higher than that of pure β-cyclodextrin polymer 5, pure 3-hydroxy-2-naphthoic acid (guest) as well as the mixture of the host and the guest (5+guest). Just because of the formation of supramolecular complex, the improvement of dielectric constant, conductivity and loss tangent of 5 resulted in the enhancement of 5′ ER effect. Meanwhile, the measurement of 2′–6′ dielectric properties was given the evidence that the molar crosslinked degree (m) of the polymer has strong influence on the supramolecular complex ER behavior as well as the host. It was found that the yield stress of the supramolecular complex ER fluid increases initially with m, reaches the maximum at m=7.53 and finally appears a decline at m=8.89, while that of the host has an enhancement trend with the increase of m.
