A new marketing mix model to rescue the hospitality industry: Evidence from Egypt after the Arab Spring
2017
After January 25th 2011 Egypt witnessed political, economic and social instability leading to drastic consequences in the hospitality and tourism industry. Thus unstable situation reflected on the deteriorated occupancy percentages that led to declined profit margins, higher employee layoffs and degraded quality of product and services. The objectives of this research is to examine how the Egyptian hospitality properties manage this dilemma through their marketing practices, and to propose a new marketing mix model that adds new layers of depth to the traditional marketing mix model. A methodological framework was designed to help in the assessment process of management practices pertaining…
Asset Tangibility, information asymmetries and intangibles as determinants of family firms leverage
2022
Using a sample of Spanish tourism small and medium-sized firms, we have tested the impact of family control, publicly-available information and tangibility on financial structure, providing a multi-theoretical model that incorporates contributions from the classical theory of finance, inspired by agency theory, the behavioural theory of the firm and strategic theory. The results point to the need to jointly consider the effects of information transmission practices, asset investment decisions and ownership structures on debt capacity. The results show how family control is associated with propensity to take on debt, so that the desire to maintain social control and socioemotional wealth pre…
Determination of Water-Soluble Trace Elements in the PM10 and PM2.5 of Palermo Town (Italy)
2022
This study contributes to the current knowledge on the solubility of trace elements in the atmospheric particulate matter of the urban area of Palermo. Daily sample filters of PM10 and PM2.5 were collected in monitoring stations within and outside the urban area, characterized by variable traffic density. The bulk of compositions in PM10 and PM2.5 were determined by ICP-MS. The water-soluble trace elements (WSTE) and major ion components of particulate matter were determined by ICP-MS and ion chromatography, respectively. A significant difference in the metals content was observed between the samples taken in urban areas and those from suburban areas. The calculated enrichment factor highli…
Cardiovascular effects of occupational exposure to urban airborne pollution on a group of newsagents in the city of Palermo
2014
Aims: To verify the possible correlation between exposure to airborne particulate matter the average size less than 10 μm (PM 10) of a group of newsagents working in kiosks in Palermo and evidence of carotid intimal thickening. Materials and methods: data were collected relating to environmental monitoring of airborne pollutants. We have selected a sample of newsagents, who were submitted to some clinical investigations, including the carotid echo-color doppler examination. Results: The results show no correlation between the location of the kiosks, and the presence of intimal thickening. Conclusion: Exposition to urban pollutants in Palermo is likely homogenous in the different areas and c…
Air quality and integration of short-term and long-term pollutant data
2008
Modelling PM10 is an important problem in statistical methodology, above all to explain the PM10 behaviour in space and time, since it has been linked to many adverse effects on human and environmental health. But the large spatial variability of the main traffic-related pollutants, and in particular here the PM10, implies the impossibility of obtaining from the data of the fixed stations a complete pictures of the atmospheric pollution in the urban areas. Information from fixed monitoring stations (long-term measurements) are therefore integrated with the ones deriving from mobile station (short-term measurements). Short-term measurements are incomplete and so it is necessary to integrate …
Integrated marketing communication as a business management tool in the context of sustainable development
2018
AbstractThe problem of nowadays is that consumers lack information on food products, their composition and quality, nutritional value, packaging, its impact on the human health and environment, reuse and recycling possibilities, etc. Integrated marketing communications (IMC) as a business management tool may not only draw the consumers’ attention and incite a purchase, but also provide information and serve as a facilitator of consumers’ knowledge and competence on products, their nutritional value, use and utilisation. The goal of the research is to assess the impact of IMC for sustainability upon demand at Latvian food retail chains and the impact of the use of IMC for sustainability upon…
Pharmacologic Inhibition of ADAM10 Attenuates Brain Tissue Loss, Axonal Injury and Pro-inflammatory Gene Expression Following Traumatic Brain Injury …
2021
The α-secretase A disintegrin and metalloprotease 10 (ADAM10) regulates various physiological and pathophysiological processes. Despite its broad functional implications during development, plasticity, and disease, no pharmacological approaches to inhibit ADAM10 in acute brain injury have been reported. Here, we examined the effects of the ADAM10 inhibitor GI254023X on the neurological and histopathological outcome after experimental traumatic brain injury (TBI). C57BL/6N mice were subjected to the controlled cortical impact (CCI) model of TBI or sham procedure and received GI254023X or vehicle during the acute phase of injury (n = 40, 100 mg/kg, 25% DMSO, 0.1 M Na2CO3, intraperitoneal, 30 …
P3‐335: Upstream of N‐ras (UNR) is involved in translational control of ADAM10 protein expression
2008
Background: The amyloid beta peptide (A ) is derived by proteolytic processing of the amyloid precursor protein (APP) by the beta-secretase BACE1 and gamma-secretase. In contrast to this amyloidogenic processing, APP is predominantly cleaved by the alpha-secretase within the A domain and this precludes the formation of A . We and other research groups could show that BACE1 protein expression is regulated by the 5’untranslated region (UTR) of the BACE1 mRNA, however little is known about the regulation of alpha-secretase. Similar to the 5’UTR of BACE1, the 5’UTR of ADAM10 consists of 444 nucleotides with a GC-content of 70% and two upstream open reading frames. We hypothesize that ADAM10, th…
Changes in atmospheric pollutants during COVID-19
2022
Bakalaura darba “Atmosfēras piesārņojuma izmaiņas COVID-19 laikā” mērķis –Identificēt un izpētīt ar COVID-19 pandēmiju saistītās izmaiņas, konkrēti, pārvietošanās ierobežojumu un dzīves veida izmaiņu, ietekmi attiecībā uz atmosfēras piesārņojuma koncentrāciju rādītājiem Latvijas Republikas galvaspilsētā Rīgā. Pētījumā analizēti dati no Latvijas Ģeoloģijas un Meteoroloģijas (LVĢMC) centra novērojumu stacijām. COVID-19 pandēmijas ietekme bija jūtama visā pasaulē, tostarp arī Eiropā, jo ārkārtas stāvokļa un pārvietošanās ierobežojumu rezultātā bija vērojamas izmaiņas emisiju dinamikā atmosfērā. Sakarā ar izmaiņām darba norisē un darbinieku pāreju uz attālināto darbu, kā arī mācību un studiju p…
Cementa ražošanas procesa tehnoloģisko risinājumu ietekmes uz gaisa kvalitāti novērtējums
2015
Maģistra darbā pētīts cementa ražošanas tehnoloģiju radītais gaisa piesārņojums un tā izplatība SIA „Cemex” rūpnīcas teritorijā, Brocēnos, kur cementa ražošanā pašlaik izmanto sausā procesa tehnoloģiju. Lai gan sausā procesa tehnoloģiskie risinājumi ir energoefektīvāki un videi draudzīgāki, ražošanas procesa rezultātā rodas būtisks cieto daļiņu piesārņojums. Pētījuma ietvaros veikts pilns cieto daļiņu novērtējuma cikls – emisiju aprēķini, piesārņojuma izkliedes modelēšana un modelēšanas rezultātu validācija izmantojot cieto daļiņu mērījumus. Mērījumi veikti ar vairakkanālu lāzerskaitīšanas metodi, modelēšana – izmantojot Gausa dispersijas modeli AerMod. Darba parādīta dažādu cementa ražošan…
