The communication effects of art on corporate reputation: An exploratory study

This paper explores how the use of art and the role of the artist impacts on corporate reputation and business success. Drawing on data from two retailers this research finds that the use of art in communication has significant impact on corporate reputation and business success. Data suggest that artwork can be used in four ways: (1) as a basis of the design of merchandise being marketed, (2) as a form of advertising synonymous with the product, and (3) as a method of stimulating PR, controversy and word of mouth in the community and (4) the establishment of a unique identity. It is argued that each of these behaviours has contributed to these firms¿ corporate re putations and that in the process emergent goodwill has developed surrounding the artists and their work. Of particular value was the contribution the artists themselves lent to the brand¿s identity, image and corporate reputatio

Examination of types in the Fragilaria vaucheriae–intermedia species complex

In a previous paper, we presented the results of type examination of the Fragilaria pectinalis–capitellata species complex, species which have a unilateral central area and fine striae. Here, we present the results of type examination of the Fragilaria vaucheriae–intermedia species complex, species which have a unilateral central area and coarse striae (＜13 striae per 10 µm). Synedra vaucheriae var. doformis Grunow and S. vaucheriae var. distans Grunow are synonyms of F. vauchriae (Kütz.) J.B.Petersen. F. intermedia Grunow is also a synonym of F. vauchriae. However, some of the figures for F. intermedia that were published by Van Heurck are a new taxon sometimes identified as F. intermedia. This new taxon is described here as Fragilaria neointermedia.This is an open access paper (Directory of Open Access Scholarly Resources).

Oral Health-Related Quality of Life of Refugees in Settlements in Greece.

INTRODUCTION: The objective of this cross-sectional study was to investigate the oral health-related quality of life (OHQoL) amongst refugees at emergency dental clinics in settlements in Northern Greece. METHODS: A self-reported survey was undertaken in 7 settlements. The American Dental Association questionnaire on oral health (OH) was adapted and distributed to adults attending a mobile dental clinic between July and August 2017. Data were collected on sociodemographics, length of stay in settlement, utilisation of dental service, and OHQoL. Statistical analysis included descriptive analysis and Chi-square tests of associations. RESULTS: Of 156 participants, the majority were male (73%), were aged 18 to 34 (59%), and had education up to high school (48%). Most of the participants rated OH as fair or poor (76%) and had spent more than 6 months in the settlements (45%). A majority of the participants (85%) had no access to dental care without the mobile clinic. Negative impact on OHQoL was significantly (P < .05) related to settlement location and time spent, smoking status, frequency of cleaning teeth and use of fluoridated toothpaste, perceived OH, and time since last dental visit. Those who spent less than 1 month in the settlement reported a higher negative OHQoL impact related to chewing, anxiety, smiling, daily activity, and sleeping (range, 48%-73%) compared to those who had spent more than 6 months (range, 17%-41%) (P < .05). CONCLUSIONS: To the best of our knowledge, this is the first cross-sectional study assessing the OHQoL of refugees seeking emergency dental care in settlements in Greece. There is evidence that the refugees who were new arrivals to the settlements when provided with access to dental care reported a negative impact on their OHQoL. There is an urgent need for further research to understand the OH needs of refugees in Europe in order to design and deliver targeted and effective interventions

Pulse-Administered Toceranib Phosphate Plus Lomustine for Treatment of Unresectable Mast Cell Tumors in Dogs.

BackgroundNonresectable mast cell tumors (MCT) in dogs remain a therapeutic challenge, and investigation of novel combination therapies is warranted. Intermittent administration of tyrosine kinase inhibitors (TKI) combined with cytotoxic chemotherapy may effectively chemosensitize canine MCT while decreasing cost and adverse effects associated with either agent administered as monotherapy.Hypothesis/objectivesThe primary study objectives were to (1) identify the maximally tolerated dose (MTD), (2) determine the objective response rate (ORR) and (3) describe the adverse event profile of pulse-administered toceranib phosphate (TOC) combined with lomustine.AnimalsForty-seven client-owned dogs with measurable MCT.MethodsToceranib phosphate was given PO on days 1, 3 and 5 of a 21-day cycle at a target dosage of 2.75 mg/kg. Lomustine was given PO on day 3 of each cycle at a starting dosage of 50 mg/m(2) . All dogs were concurrently treated with diphenhydramine, omeprazole, and prednisone.ResultsThe MTD of lomustine was established at 50 mg/m(2) when combined with pulse-administered TOC; the dose-limiting toxicity was neutropenia. Forty-one dogs treated at the MTD were evaluable for outcome assessment. The ORR was 46% (4 complete response, 15 partial response) and the overall median progression-free survival (PFS) was 53 days (1 to &gt;752 days). On multivariate analysis, variables significantly associated with improved PFS included response to treatment, absence of metastasis, and no previous chemotherapy.Conclusions and clinical importanceCombined treatment with pulse-administered TOC and lomustine generally is well tolerated and may be a reasonable treatment option for dogs with unresectable or metastatic MCT

Gaian bottlenecks and planetary habitability maintained by evolving model biospheres: The ExoGaia model

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.The search for habitable exoplanets inspires the question - how do habitable planets form? Planet habitability models traditionally focus on abiotic processes and neglect a biotic response to changing conditions on an inhabited planet. The Gaia hypothesis postulates that life influences the Earth's feedback mechanisms to form a self-regulating system, and hence that life can maintain habitable conditions on its host planet. If life has a strong influence, it will have a role in determining a planet's habitability over time. We present the ExoGaia model - a model of simple 'planets' host to evolving microbial biospheres. Microbes interact with their host planet via consumption and excretion of atmospheric chemicals. Model planets orbit a 'star' which provides incoming radiation, and atmospheric chemicals have either an albedo, or a heat-trapping property. Planetary temperatures can therefore be altered by microbes via their metabolisms. We seed multiple model planets with life while their atmospheres are still forming and find that the microbial biospheres are, under suitable conditions, generally able to prevent the host planets from reaching inhospitable temperatures, as would happen on a lifeless planet. We find that the underlying geochemistry plays a strong role in determining long-term habitability prospects of a planet. We find five distinct classes of model planets, including clear examples of 'Gaian bottlenecks' - a phenomenon whereby life either rapidly goes extinct leaving an inhospitable planet, or survives indefinitely maintaining planetary habitability. These results suggest that life might play a crucial role in determining the long-term habitability of planets.We thank the Gaia Charity and the University of Exeter for their support of this work
