Does tradeoff between financial and social indicators matters in environmental consideration: evidence from G7 region

The study tries to discover the impact of financial and social indicators’ growth towards environmental considerations to understand the drivers of economic growth and carbon dioxide emissions change in G7 countries. The DEA-like composite index has been used to examine the tradeoff between financial and social indicator matters in environmental consideration by using a multi-objective goal programming approach. The data from 2008 to 2018 is collected from G-7 countries. The results from the DEA-like composite index reveals that there is a mixed condition of environmental sustainability in G-7 countries where the USA is performing better and Japan is performing worse among the set of other countries. The further result shows that the energy and fiscal indicators help to decrease the dangerous gas emissions. Divergent to that, the human and financial index positively contributes to greenhouse gas emissions. Fostering sustainable development is essential to successfully reduce emissions, meet established objectives, and ensure steady development. The study provides valuable information for policymakers.

     

Belgian Consumers’ Opinion on Pork Consumption Concerning Alternatives for Unanesthetized Piglet Castration

Male piglets in Belgium are still castrated unanesthetized in the first week of life, but animal rights organizations, supermarkets, and some consumers no longer accept this method in terms of animal welfare, and are pushing the pig industry to apply available alternative methods. This major change in pig husbandry will increase production costs without a guarantee for return of investment by consumers. Therefore, it is important to know the opinion of consumers on this matter. A questionnaire was used to collect data from 1,018 people through face to face interviewing in Flanders. A Chi-square test and Fisher’s exact test were used to analyze the data. Results show that in spite of several media campaigns of animal welfare organizations over the past few years, still half of the Flemish respondents were not aware of the problem of unanesthetized piglet castration. However, after being informed, the majority wanted unanesthetized castration to be banned. Although the concern about animal welfare implications was very high, the willingness to pay extra for alternatives was low.     

Structure and function of Halice hesmonectes (Amphipoda: Pardaliscidae) swarms from hydrothermal vents in the eastern Pacific

Swarms of the pardaliscid amphipod Halice hesmonectes were sampled at low-temperature hydrothermal vents in the Venture Hydrothermal Fields of the East Pacific Rise. In excess of 3000 individuals were collected from a range of sites/habitats, and at two points in time (December 1991 and March 1994). The structure of swarms was described in terms of growth stages, the development of primary and secondary sex characteristics and the accumulation of nutritional reserves. The results demonstrated that swarms contained a wide range of growth stages, but that small juveniles and mature males and females were absent. Swarm structure was interpreted as an equilibrium dependent on the relative proportion of time spent by each growth stage in the swarm habitat. This equilibrium swarm structure was very similar at different sites and times. Swarms dominated by small juveniles occurred at the northern sites in December 1991 following a period of eruption and new venting in April 1991. Equilibrium swarm structure had become re-established at these sites by March 1994. The function of swarming was considered. The results indicated that swarming was not associated with reproductive activity. The available evidence, though not conclusive, suggested that swarms were associated with feeding.
