The Importance of Understanding Cultural Awareness for Managers in the Hospitality Industry (in Indonesia)

Cultural awareness is a basic knowledge that each individuality must has. In hotel industry, there are positive advantages that could be reached if a manager could appreciate a cultural, value, attitude differences of each person. This paper adjusts how important the understanding of cultural diversity and pragmatic implementation from several cross cultural communication theory, especially for managers in hotel industry. This paper also describes examples of cultural attitude and habits from some countries that could be refferences in workforce diversity

Modelling Modal Shift Preference of Freight Transport on Surabaya-Jakarta Corridor : A Preliminary Survey

The market share of freight transport which is dominated by road transport and accompanied by unbalanced of infrastructure’s growth and freight demand has created various negative impacts on existing transportation system. The shift of freight transport from road to rail and sea is expected to reduce those impacts. Research on the behavior of freight mode choice and the extent to which the user is willing to trade off the attribute change needs to be done so that the amount of modal shift will be known. The main objective of the study was to produce a model of mode choice based on preference surveys among forwarders, as well as to provide inputs for policy improvement and or improvement of freight transportation services. One of the surveys to be conducted is the revealed preference (RP) survey. The important stage before the RP survey is to conduct a preliminary survey. This stage aims to determine the important trends related to the choice of modes by the forwarder and test the response rate of respondents. The survey is also useful for assessing the credibility of the data instrument, identifying potential errors in the data instrument, and determining non-conformities in survey management before the actual survey. Data collection was done by sending questionnaires. The structure of the questionnaire consists of questions about characteristics of : shipment, travel, and modes. The results of survey showed relatively low response rate because it was only 8 respondents who were willing to answer the questionnaire. This indicates that the questionnaire needs to be combined with other methods, such as: face to face interviews and or focus groups. The results of the preliminary survey show that the main factors for the choice of existing modes are: shipment costs, loss/damage, and time travel. The implementation of the next stage survey should consider that each company has more than one shipping commodity so it is necessary to group questions and analysis based on each commodity

Spatio-Temporal Analysis of Dengue and Weather Variables in Yogyakarta

BACKGROUND: Dengue Hemorrhagic Fever (DHF) is one of the main public health issues in Indonesia, and is endemic in all provinces. The annual incidence of DHF has been fluctuated in Yogyakarta. This study aimed to examine the pattern of the relationship among weather variables on the incidence of dengue in the city of Yogyakarta for 5 years (2010-2014). SUBJECT AND METHODS: This was an ecological study with spatio-temporal approach. The study population was the incidence of dengue for the period 2010-2014 in Yogyakarta city. The independent variables in this study were rainfall, temperature, relative humidity, and wind velocity. The dependent variable was the incidence of DHF. The data was analyzed using graphic/time-trend and spatial statistical analysis. Rainfall in theory increases mosquito breeding place. In this study, however, rainfall was not included in fitting the regression analysis model. RESULTS: There was a relationship among weather variable with dengue incidence, both in graphs/time-trend and spatial statistic analyses. In the graph/time-trend and spatial analysis, there was a relationship between dengue outbreaks in 2010 and 2013 in rainfall fluctuations and temperature. Two regressions models were used, i.e. Poisson Regression and Negative Binomial Regression. The smallest Akaike‟s Information Criterion (AIC) and Bayesian Information Criterion (BIC) values were used to indicate model fit with respect to the contribution of weather variables on dengue incidence. The incidence of dengue at a lag of one month, temperature of the same month, temperature at the lag of two months, relative humidity of the same month, relative humidity at the lag of three months, and wind velocity at the lag of two months, were predictors for dengue incidence. CONCLUSIONS: The pattern of dengue incidence following climate fluctuation, rainfall lag of two months, temperature lag of three months, humidity in lag of one month, had positive association with increased incidence of dengue. Wind velocity was inversely associated with dengue incidence of the same month. The policy implication of the study is that the Health Office of Yogyakarta city should consider climatological data in surveillance and planning dengue prevention program. Keywords: dengue hemorrhagic fever, vector-borne disease, climate, spatio-temporal analysi

Ekstraksi dan Uji Kestabilan Pigmen Betasianin dalam Kulit Buah Naga (Hylocereus Polyrhizus) Serta Aplikasinya sebagai Pewarna Tekstil

Kulit buah naga merupakan limbah makanan yang belum dimanfaatkan dan dapat dijadikan sebagai sumber pigmen merah alami karena mengandung pigmen betasianin. Pigmen betasianin dapat diaplikasikan sebagai pewarna tekstil. Penelitian ini bertujuan untuk mengekstrak pigmen betasianin dalam kulit buah naga dengan metode maserasi menggunakan pelarut etanol 80% lalu ekstrak pigmen betasianin yang diperoleh diaplikasikan sebagai pewarna tekstil dengan proses pencelupan. Ekstrak pigmen betasianin dianalisis menggunakan spektrometri visible dan dilakukan uji kestabilan pigmen betasianin terhadap temperatur dan pH. Uji kestabilan terhadap temperatur dilakukan dengan variasi temperatur 25°C, 40°C, 60°C, 80°C and 100°C, sedangkan uji kestabilan terhadap pH dilakukan dengan variasi pH 2.5; 3.5; 4.5; 5.5; 6.5; 7.5; 8.5 and 9.5. Ekstrak yang diperoleh diuji kestabilannya dengan perlakuan pemanasan dan dipaparkan sinar matahari kemudian dilakukan penguapan pelarut dan ekstrak dapat diaplikasikan pada kain dengan metode mordanting dan pencelupan langsung. Hasil penelitian yang diperoleh adalah ekstrak pigmen betasianin dengan rendemen 3,735%. Ekstrak pigmen betasianin paling stabil pada temperatur 25°C dan pada pH 4,5. Ekstrak yang diperoleh stabil terhadap pemanasan dan paparan sinar matahari serta dapat diaplikasikan terhadap kain. Pigmen betasianin menimbulkan warna yang dapat menempel pada kain dengan baik

Quarkonia production with the Hera-B experiment

Measurements of the dependence of the J/Psi production cross section on its kinematic variables as well as on the target atomic numbers for 920 GeV/c protons incident on different targets have been made with the Hera-B detector. The large collected di-lepton sample allows to study the production ratio of Psi(2S) to J/Psi and of Chic to J/Psi . We also report on measurements of the b-bbar and Upsilon production cross section.Comment: 9 pages, 11 figure

Fusarium oxysporum Casein Kinase 1, a Negative Regulator of the Plasma Membrane H+-ATPase Pma1, Is Required for Development and Pathogenicity

Like many hemibiotrophic plant pathogens, the root-infecting vascular wilt fungus Fusarium oxysporum induces an increase in the pH of the surrounding host tissue. How alkalinization promotes fungal infection is not fully understood, but recent studies point towards the role of cytosolic pH (pHc) and mitogen-activated protein kinase (MAPK) signaling. In fungi, pHc is mainly controlled by the essential plasma membrane H+-ATPase Pma1. Here we created mutants of F. oxysporum lacking casein kinase 1 (Ck1), a known negative regulator of Pma1. We found that the ck1Δ mutants have constitutively high Pma1 activity and exhibit reduced alkalinization of the surrounding medium as well as decreased hyphal growth and conidiation. Importantly, the ck1Δ mutants exhibit defects in hyphal chemotropism towards plant roots and in pathogenicity on tomato plants. Thus, Ck1 is a key regulator of the development and virulence of F. oxysporum
