Willingness to Whistle Blow Among Muslim Consumers

The paper reports on a qualitative study using three focus groups drawn from Muslim consumers both local and foreign. Respondents were given vignettes depicting unethical halal claims scenarios to which respondents were required to respond. Two Malaysian consumer groups responded by declaring that they will whistle blow by reporting the matter to a religious authority, the Islamic Development Department （JAKIM）, while another group that consists of six Muslim foreign students will just leave the business premise without making any complaints to any authority. The different course of actions taken could be explained by the diverse background of the Malaysian population and their level of awareness in selecting their halal food and their high degree of intolerance to such practice whilst the level of tolerance among foreign Muslim respondents might be different from their Malaysian counterparts or that they have never encountered such a problem before they came to Malaysia, The study also reports the response from JAKIM in relation to the relevant channels for whistle blowing regarding misleading halal labels.

A clinicoepidemiological study of esophageal cancer patients at the National Cancer Institute,Cairo University,Egypt

Objective The purposes of this study were to （1） assess the clinicoepidemiological characteristics of esopha-geal cancer patients, （2） analyze the prognostic factors determining treatment failure and survival, and （3） evaluate the results of various treatment modalities for locoregional and disseminated disease and their ef ect on disease-free survival and overal survival （OS）.Methods Clinicoepidemiological retrospective data from 81 esophageal cancer patients treated at the Na-tional Cancer Institute of Cairo between 2007 and 2011 were evaluated. Results The study showed that patients with esophageal cancer commonly present with local y advanced disease （87.7% had T-stage 3 and 12.3% had T-stage 4）. There was a significant correlation between surgery and survival; patients who received radical surgery and postoperative radiation had a better median survival than patients who received radical radiotherapy （20 months vs. 16 months, respectively; P = 0.04）. There was also a significant statistical correlation between radical concomitant chemoradiotherapy （NCRT） and pal iative treatment. Patients who received radical NCRT had a better median survival than patients who received pal-liative radiotherapy （16 months vs. 10 months, respectively; P = 0.001）. The median fol ow-up period for al patients was 7 months. The median OS of the whole group was 12 months. The OS after 1 and 2 years was 57.8% and 15%, respectively.Conclusion High-dose NCRT is an acceptable alternative for patients unfit for surgery or with inoperable disease. High-dose radiation is more ef ective than low-dose radiation in terms of local control, time to relapse, and OS. Further study using a larger series of patients and introducing new treatment protocols is necessary for a final evaluation.

Foraging areas of Rousettus leschenaulti on the Hainan Island of China

We investigated the foraging area of three individuals (1 female and 2 males) of Rousettus leschenaulti (Chiroptera,Pteropodidae) in suburban Haikou City, Hainan Province, South China from November 2005 to January 2006 using radio telemetry.These animals left the daytime roosting sites about 90 min after sunset with no significant difference in departure time betweenthe male and female bats. The average active times were 391.8 min for males and 533.7 min for the female, respectively.By reconstructing 93 radio-telemetry recording positions, we found that the long axis of foraging area of the bats ranged from7.45 to 11.70 km. The foraging area of the female (3867 ha) was larger than that of the males (1138 ha), and there was overlapbetween the foraging areas of different individuals. These bats usually kept the same flight routes across a few successive daysfrom the daytime roosting site to the foraging areas. Our findings suggested that female R. leschenaulti may explore a larger foragingarea than males. No obvious territorial behaviors were observed in our studied area.

Comparison of Efficiencies of Enterprises Engaged in Food Sector in Turkey by Data Envelopment Analysis Taking Account of Their Efficiencies and Rantability Rates

Enterprises are in competition with other enterprises operating in their fields. In today＇s world, enterprises need to increase their efficiency and productivity, the values of which, if below market conditions, they need to raise. Data Envelopment Analysis, widely utilized in efficiency and productivity measurements is a method that measures the efficiency of one unit relatively, taking more than one input determines the efficiency of units with similar inputs and outputs and output simultaneously. DEA interactively Thus, not only the efficient units are determined, but an opinion is offered as to how the inefficient units can be improved. In this study, 12 enterprises that were among the first 500 enterprises in Turkey in 2008, active in Istanbul Stock Exchange and operating in food sector through Data Envelopment Analysis. In the model, activity rates were used as input values, rantability rates were used as output values. In conclusion of simultaneous analysis of input and output values, efficient and inefficient enterprises were determined.

Implementation of Food Safety Legislation in Catering Establishments in Latvia

The aim of the research was to evaluate overall quality of introduction of hazard analysis and critical control points （HACCP） prerequisites and HACCP procedures in catering sector in Latvia to reveal common problems that can provoke food-borne infection outbreaks. Certain quantitative indicators were defined and analyzed to conclude about characteristic trends related to implementation of food safety legislation. The state＇s monitoring data on surveillance of catering establishments were used. Fulfillment of legislative requirements in about 6,000 catering establishments was evaluated during time period of 2004-2009. The results of investigation were obtained with help of statistical analyses using MS Excel computer program. The results of the research suggest that most of catering establishments （e.g., 83.6% during 2009） meet the hygiene requirements only partly. Non-conformities regarding HACCP-based self-control procedures were fixed during 49.2% of inspections. The research reveals characteristic shortcomings that are established from year to year, e.g., improper hygiene of premises （established during 30%-40% of inspections, depending on the year）, poor hygiene of technological equipment （established during 27%-37% of inspections）, poor personnel hygiene （established during 11%-22% of inspections）, inadequate competence of food service personnel （established during 10%-35% of inspections）, as well as non-observance of cleaning-disinfection procedures and technological parameters for food processing （established during 11%-25% of inspections, depending on the year）. Actual shortcomings can lead to both the direct and the indirect cross-contamination of food. On the base of the research, it was concluded that further detailed assessment of potential food safety risks is relevant to establish risk-based monitoring activities in catering sector.

《庄子》

《庄子》中包含大量探讨生死的内容,所得出的结论与见解常常独到又意味深长。妻子死后,庄子鼓盆而歌,他认为生死的过程如四季轮回,因而旷达;庄子临死之前,让弟子将自己的尸体抛之荒野,弟子担忧这样尸体会被鸟兽吃了,庄子说埋在地下也是为蝼蚁所食,鸟兽与蝼蚁又有什么区别呢?

Existence of spatiotemporal patterns in the reaction-diffusion predator-prey model incorporating prey refuge

The pattern formation in reaction-diffusion system has long been the subject of interest to the researchers in the domain of mathematical ecology because of its universal exis- tence and importance. The present investigation deals with a spatial dynamics of the Beddington-DeAngelis predator-prey model in the presence of a constant proportion of prey refuge. The model system representing boundary value problem under study is subjected to homogeneous Neumann boundary conditions. The asymptotic stability including the local and the global stability and the bifurcation as well of the unique pos- itive homogeneous steady state of the corresponding temporal model has been analyzed. The Turing instability region in two-parameter space and the condition of diffusion- driven instability of the spatiotemporal model are investigated. Based on the appro- priate numerical simulations, the present model dynamics in Turing space appears to get influenced by prey refuge while it exhibits diffusion-controlled pattern formation growth to spots, stripe-spot mixtures, labyrinthine, stripe-hole mixtures and holes repli- cation. The results obtained appear to enrich the findings of the model system under consideration.
