Livers from 108 birds found prostrate or dead in Ilha Grande Bay between 2005 and 2010 were analyzed for 16 PCB congeners (IUPAC numbers 8, 18, 28, 31, 52, 77, 101, 118, 126, 128, 138, 149, 153, 169, 170, and 180). The species analyzed were Egretta caerulea (Linnaeus 1758), Nycticorax nycticorax (Linnaeus 1758), Egretta thula (Molina 1782), and Ardea cocoi (Linnaeus 1766). The analysis were performed using Origin software (7.5, 2004) with a significant level of p<0.05. Data were checked for adherence to the standard assumptions of parametric tests using the Kolmogorov-Smirnov test for normality and the Levene's test for homogeneity of variances. This has revealed differences in concentration for some congeners. Results indicate relatively low PCBs contamination in aquatic birds, but it is implied the close relationship of environmental contamination, showing potential power of widespread biological and mutagenic adverse effects in trophic levels, and therefore, signalling risk to human health.

This study focuses on metals analysis in kidney and liver tissues of Egretta thula which were collected prostrate or newly dead in Coroa Grande mangrove, Sepetiba Bay, Rio de Janeiro, Brazil, between March 2005 and October 2008. Kidney and liver were collected and analysed to evaluate heavy metal pollution. High values and widest range were detected for all metals in liver and kidney tissues. Geometric mean differences from metals concentrations for Zn, Cd, Ni, Pb, Cu, and Cr, respectively, were found in both organs. Results from linear regression analysis were non-significant in kidney (r = -0.79975, P = 0.10428), and in liver (r = -0.53193, P = 0.35618). With ANOVA analysis for metal accumulation differences (kidney*liver), at the 0.05 level, the results were significantly different (F = 33.17676, P = 0.00000; F = 12.47880, P = 0.00000). These results indicate that Sepetiba Bay shows worrying levels of metals in this study with E. thula, showing potential power of widespread biological and mutagenic adverse effects in trophic levels, and therefore, signalling risk to human health.

The Relationship

The stigma about COVID-19 sufferers along with the effects of stigma messages is now increasingly attached to the lives of people, especially those living in the environment around COVID-19 sufferers and or survivors. Not only for sufferers, said stigma today is also attached to marked supporters because of its existence that has a close relationship with sufferers. Stigma arises as a result of the community's complete lack of understanding of COVID-19 itself. The effect is not missed in influencing the communication between individuals and each other. This also happens in Kauman Village Yogyakarta where stigma and its effects are felt by many marked supporters. This is unique because so far the stigma has hit the sufferer more often, but not in this case, the stigma is more about marked supporters. Seeing the phenomenon, the question arises how stigma affects the relationship of marked supporters to the community in Kauman Village Yogyakarta after the message of stigma. This study uses a case study method. The focus of this study is the stigma about COVID-19 sufferers who hit marked supporters and the effect of stigma messages that appear on marked supporters after being hit by stigma messages. The findings suggest that the effect of stigma messages on each individual results in different findings depending on how the acceptance of the stigma message is then able to influence the interpersonal relationship between the marked supporters and the public in general.

The retail market in Vietnam continues to grow with the entry of foreign retail brands and the strong rise of domestic businesses in expanding distribution networks and conquering consumer confidence. The appearance of more retail brands has created a fiercely competitive market. Based on the outcomes of previous research results on brand choice intention combined with a customer survey, the paper proposes an analytical framework and scales to examine the relationship of five elements including store image, price perception, risk perception, brand attitudes, brand awareness and retail brand choice intention with a case study of the Hanoi-based Circle K convenience store chain. These five elements are the precondition for retail businesses to develop their brands so as to attract customers.

Cooperation Policy

Several studies have shown that the success of interregional cooperation may be influenced by coordination, commitment, participation, variance of cooperation, structure, format of cooperation, and political will. Nevertheless, these factors do not stand alone since actor relations as a determining aspect is capable of driving those factors effectively. This article aims to examine the aspect of actor relations as a contributing factor that determines successful cooperation among regions. This is a qualitative research with the policy of inter-regional cooperation of the Banjarbakula Program, South Kalimantan Province from February 2017 to February 2018, set as its object of study. The result of this study states that the success of inter-regional cooperation is influenced by the relationship of actors in development factors as suggested by previous experts. The actors involved in the inter-regional cooperation examined in this case had become triggers of coordination, commitment, and participation toward success and failure, as well as the effectiveness of regional cooperation policy. Structural obstacles, ego-centric character, minimum budget availability, and non-visionary planning could be overcome as long as actor relations were properly managed.

The following notes were assembled in arranging the Protarchoides material in the National Collection. In establishing the identity of Protarchoides mellipes (Prov.) it has been found necessary to synonymize one species. A species allied to mellipes is described as new and a table is provided for the separation of the four known North American species. The recording of Trichiosoma as host for a member of this genus is further evidence of the close relationship of the genus with Protarchus Foer.
