Using an educational video-briefing to mitigate the ecological impacts of scuba diving

Recreational scuba diving is rapidly increasing, and the negative impacts to marine reef biota are of conservation concern. Educational approaches have been tested to mitigate diver damage to benthic organisms, but logistical constraints impede their implementation in many locations. We investigated the behaviors of scuba divers in terms of their contacts with benthic organisms, and assessed how an educational video-briefing caused changes in diver behavior. The video provided environmental information to divers, and enhanced their use of low-impact diving techniques. Divers who received the video-briefing exhibited significantly lower rates of contact with and damage to the benthos, than did divers who did not receive a briefing. The level of diving experience did not correlate with the rate of benthic contact in either group of divers. Male divers and photographers both contacted the benthos significantly less, and female divers and photographers both caused significantly less damage when they viewed the video-briefing prior to diving. Our findings highlight the importance of easily implemented, standardized educational approaches such as the use of video-briefings to mitigate the impacts of scuba diving. This study adds to the framework of tested strategies available to support the sustainable use of marine areas by the diving tourism industry.     

The evolving role of large and medium farms on Brazilian agriculture

We use Brazilian agricultural censuses data since 1970 to describe land structure evolution in Brazil, focusing on the most important agricultural commodities and livestock products across regions. The analysis reveals a remarkable stability in the number of farms in the period, as well as in the structure of land distribution across farm sizes, with a persistence of a dual agricultural structure. Land distribution, as measured by the GINI index, has changed very little and is still very high. The number of large farms is increasing significantly in time, while the number of farms with area below 500 ha changed little in the 1970–2006 period. Medium‐sized and large farms, although heavily outweighed in numbers, account for the highest share of annual crop production currently, and their share in crop (annual plus permanent) production value increased between 1980 and 2006, while the same share decreased for smaller farms. We conclude that the observed stability will probably reduce in the future, as economic forces will likely change the balance in favor of an increase in the number of large farms. This is an issue of obvious political importance, especially considering the importance of the smaller farms for employment in agriculture.     

Economic Analysis of the Policy for Accreditation of Dairy Farms Free of Bovine Brucellosis and Tuberculosis: Challenges for Small and Large Producers in Brazil

One of the cornerstones of the National Program for Control and Eradication of Bovine Brucellosis and Tuberculosis in Brazil is the voluntary accreditation of free herds. We developed a stochastic cost–benefit analysis model for two types of dairy herds (high yield Holstein‐Zebu crossbred females and lower productivity smaller scale herds) to identify the technical and economic constraints of this process. The initial prevalence of infected animals and the impact of the disease in the structure and performance of the herd were derived from secondary data. Information on the costs and benefits of herd sanitation were compiled into a cost–benefit model at the herd level. The last step consisted of a scenario simulation to evaluate the impact of alternative policies to the certification process. For each scenario, we calculate the probability over time of a Benefit–Cost Ratio greater than 1 and of an Internal Rate of Return above 1% (the discount rate used in the model). Results show that larger and more intensive dairy farms, and also herds affected by brucellosis compared with tuberculosis‐positive herds, are more likely to achieve financial gains from the certification investment. The compensation for culled animals is important in the initial phase of herd sanitation and the premium payment on milk would help farmers to achieve a return on the investment over time. The model can be adapted to different and dynamic production, epidemiological and economic settings.     

Feeder Cattle Options: Where’s the Beef?

Feeder cattle is one of the most important commodities in the livestock industry worldwide. Nonetheless, beef production is subject to many uncertainties; therefore, the risk management tools that agents use must be efficient. This article discusses the financial options available in the Brazilian futures market to feeder cattle producers and describes the best risk pricing model to determine the option premium. Our results consider several option pricing models and different types of volatility. The best pricing is obtained with the model of Bjerksund and Stensland with the implied volatility.     

Public finance,government spending and economic growth: the case of local governments in Brazil

The impact of local government spending on output growth is estimated using a panel of Brazilian municipalities during 1985–1994. Attention is focused on three expenditure categories, housing/urbanization, health/sanitation, and transport services, which are expected to be growth-enhancing, and their sources of finance (local taxes, intergovernmental transfers, and borrowing). The determinants of these spending categories are also examined. The size of the municipality, measured by the resident population, is shown to affect government spending nonlinearly. This is a contribution to the recent empirical literature on the linkages between decentralized government spending, public finances, and economic growth at the local, rather than national, level.     

Green Product Development and Product Portfolio Management: Empirical Evidence from an Emerging Economy

Few studies have explored the relationship between green products development (GPD) and product portfolio management (PPM). When considering evidence from emerging economies, the knowledge gap is even deeper. Consequently, the objective of this work is to analyze how green and traditional practices of new product development (NPD) influence product portfolio and NPD performance. In addition, we explore how GPD opens new markets and technology opportunities. The empirical evidence is based on a sample of firms that are developing products and belong to innovative industrial sectors in Brazil. In general, the framework developed and tested in this research indicates the following: (i) the adoption of GPD practices significantly influences product portfolio performance; (ii) the adoption of GPD practices tends to generate positive results with regard to obtaining technological and market opportunities; (iii) the adoption of traditional PPM practices influences the dependent factors. Unexpectedly, correlations between a firm's size or age and its performance were not confirmed. This is the first empirical evidence relating GPD, PPM, and market and technology opportunities in Brazil. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

The Marisol case: Challenges of international growth for a successful Brazilian designer apparel firm

Marisol has forged a successful legacy in Brazil in the market for clothes with a sophisticated, stylish look. Success in Brazil enabled the firm to garner overseas customers. The establishment of subsidiaries in Argentina, Italy and Mexico, as well as sales operations in several countries – including Chile, Colombia, Spain, and the USA, among others – represented important steps in Marisol's internationalization. Marisol's executives have to decide on several issues: how to consolidate their position in the USA market and in other countries? What modes of operation – own stores, franchisees, multi-brand stores, private label supply – to use in which countries? Which brands to launch abroad and whether to adapt them to local tastes, while exploiting the image of Brazilianness?
