Abstract The Nantucket pine tip moth (NPTM) [Rhyacionia frustrana (Comstock)], a native regeneration pest on young loblolly pines (Pinus taeda L.), negatively impacts pine growth. An emerging management approach is to apply systemic insecticides to seedlings to reduce NPTM damage. These systemic insecticide applications generally occur once, perhaps twice, during the first few years of loblolly pine growth. However, these applications could lead to unintended environmental consequences to nontarget organisms. The purpose of this study was to assess potential nontarget effects from four systemic insecticide applications by assessing ground-dwelling arthropod trap catch, with a focus on collembolan trap catch and genera richness. Loblolly seedlings (24 seedlings per plot) at three sites in southeast Georgia were treated with either chlorantraniliprole, dinotefuran, fipronil, or imidacloprid or left untreated as a control. Arthropods were collected with pitfall traps that were deployed for 5 d in July, August, and September 2019, 7–9 mo after treatment. Ground-dwelling arthropod trap catch, arthropod order trap catch, collembolan trap catch, and collembolan genera richness did not vary among insecticide treatments and the untreated control in this mid-term insecticide risk assessment. While no significant effects of insecticide treatment were observed, ground-dwelling arthropod trap catch, collembolan trap catch, and collembolan genera richness differed among collection times. This study was the first of its kind in a young pine stand setting and is an important first step to understanding risk in these settings. Information on nontarget risks of management practices informs growers of the level of environmental risk associated with systemic insecticides.

Large-scale mining activities have a huge impact on the environment. Determination of the size of the effect and monitoring it is vital. In this study, risk assessment studies in mining areas and the effect of mining on groundwater and ecosystems were investigated. Best management practices and risk assessment steps were determined, especially in areas with huge amounts of mining wastewater. The pollution of groundwater and its reaching humans is a risk of major importance. Our study showed, using many cases with different parameters and countries, that the management of mining wastewater is vital. Environmental impact assessments and monitoring studies must be carried out before operation and at the closure of the mine. Policies must be in place and ready to apply. Factors of climate, geology, ecology and human health must be considered over a long period. Currently, only the developed countries are applying policies and paying attention to the risk. International assessments and health risk assessments should be carried out according to international standards.

Low Levels

Throughout the past decade much research has been directed towards identifying the occurrence, epidemiology, and risks associated with waterborne protozoa. While outbreaks are continually documented, sporadic cases of disease associated with exposure to low levels of waterborne protozoa are of increasing concern. Current methodologies may not be sensitive enough to define these low levels of disease. However, risk assessment methods may be utilised to address these low level contamination events. The purpose of this article is to provide an introduction to microbial risk assessment for waterborne protozoa. Risk assessment is a useful tool for evaluating relative risks and can be used for development of policies to decrease risks. Numerous studies have been published on risk assessment methods for pathogenic protozoa including Cryptosporidium and Giardia. One common notion prevails: microbial risk assessment presents interesting complications to the traditional chemical risk assessment paradigm. Single microbial exposures (non-threshold) are capable of causing symptomatic illness unlike traditional chemical exposures, which require a threshold to be reached. Due to the lack of efficient recovery and detection methods for protozoa, we may be underestimating the occurrence, concentration and distribution of these pathogenic micro-organisms. To better utilize the tool of microbial risk assessment for risk management practices, future research should focus in the area of exposure assessment.

Espoused Values

This research examines how a misalignment between an organization’s espoused values and its realized practices regarding diversity affects employees’ commitment, organizational identification, and turnover intentions. Further, it investigates whether these relationships are mediated by perceived organizational authenticity. Using an experimental methodology, Study 1 tests the interaction between an organization’s diversity management approach (espoused values) and its demographic representativeness (realized practices). In Studies 2 and 3, an intervention based on previous research involving hypocrisy and two-sided messaging is tested. In Study 4, an employee survey further supports the hypothesized mediation. These findings are relevant for any organization seeking to increase the effectiveness of its diversity management practices.

Funding constraints and management practices are increasing pressure on clinicalautonomy within Australian mental health services. The introduction of total qualitymanagement, output-based funding and changes to public mental health policy havepromoted business-like efficiency and increased control of resources. It is argued thatsuch moves significantly circumscribe the discretionary authority that mental healthprofessionals have previously enjoyed. This paper attempts to highlight the ethical andmoral tension inherent within a corporate management approach, and calls formental health services to acknowledge the value of intellectual capital, creativity andinnovation.

Climate change is a major threat to agricultural food production globally and locally. It poses both direct and indirect effects on soil functions. Thus, agricultural management practices has evolved to adaptation strategies in order to mitigate the risks and threats from climate change. The study concludes with a recommendation the coconut farmers should explore the idea of soil biodiversity in a bid to mitigate the potential negative impact of climate related risk on the farming. The study proffers the need for adopting sustainable agricultural practices to boost local coconut production. This can contribute to the simultaneous realisation of two of the Sustainable Development Goals (SDGs) of the United Nations: SDG 2 on food security and sustainable agriculture and SDG 13 on action to combat climate change and its impacts. The study findings has implications for tackling climate change in Sub-Saharan Africa and in particular Nigeria in order to boost local agricultural production and coconut in particular without negative environmental consequences and an ability to cope with climate change related risks.

O turismo, como fenômeno socioespacial baseado nos deslocamentos humanos, é motivado principalmente pelo consumo de paisagens. Ao se instalar em um determinado lugar, o turismo desencadeia diversas transformações econômicas, sociais, culturais e ambientais. Fatores internos e externos interferem no ciclo de desenvolvimento dos lugares turísticos. A adequação das tipologias turísticas à realidade local e a forma de gestão da atividade, considerando as características singulares de cada paisagem, são os fatores centrais que determinam os tipos de efeitos que serão ocasionados. Para as populações receptoras os efeitos do turismo são diretos uma vez que a atividade dinamiza o cotidiano local. Este trabalho tem como recorte espacial de análise o povoado Pontal de Coruripe, localizado no município de Coruripe, litoral sul alagoano. Conhecido pelo artesanato em palha de ouricuri e por suas belezas naturais, como todo espaço receptivo Pontal de Coruripe sofre as influências decorrentes da sua turistificação. Este estudo tem como objetivo compreender a constituição e desenvolvimento do Pontal do Coruripe como lugar turístico, por meio da caracterização de seu ciclo de vida turístico. O modelo do ciclo de vida do lugar turístico, conhecido na literatura internacional pela sigla TALC (Tourism Area Life Cycle), foi publicado por Richard W. Butler, em 1980, e desde então vem sendo utilizado para o estudo de destinações, lugares ou atrativos turísticos, visando identificar o estágio atual em que o objeto estudado se encontra e, por conseguinte, a visualização da trajetória passada e possíveis caminhos futuros. O ciclo de vida de Pontal de Coruripe foi analisado a partir das dimensões econômica e social, considerando o recorte temporal que se estende desde o período anterior à chegada do turismo ao lugar, antes de 1985, até o ano de 2015. O trabalho se caracteriza como um estudo de caso com abordagem metodológica qualitativa. Os sujeitos da pesquisa são os gestores dos meios de hospedagem. Os dados foram coletados através de entrevistas com roteiros semiestruturados, observação direta, levantamento fotográfico e pesquisa documental. O trabalho apresenta o histórico da oferta de unidades habitacionais no destino, as características do seu ciclo de vida, assim como as expectativas relacionadas ao futuro do turismo em Pontal de Coruripe. Tourist life cycle of a sea-side place: the case of Pontal de Coruripe (AL, Brazil) ABSTRACT As a socio-spatial phenomenon based on leisure travel, tourism is motivated mainly by the consumption of landscapes. When tourism is inserted in a place it unleashes a change process with economic, social, cultural and environmental consequences. Both internal and external factors influence a place’s tourism development cycle. Tourism typologies adapted to local characteristics and the management approach in accordance with the singular characteristics of each landscape are the key factors determining the types of caused effects. Tourism development causes direct impacts on host communities as tourist activities change the daily local socio-economic dynamics. This work focuses on Pontal de Coruripe, a community of the municipality of Coruripe which is located in the south littoral of the Alagoas state, Brazil. Pontal de Coruripe, known for its handicraft made from leaves of the ouricuri palm tree as well as for its beautiful natural characteristics, is affected by its touristification. The objective of this study is to understand the formation and development of Pontal de Coruripe as a tourist place on the basis of its tourist area life cycle.The model of the tourist area life cycle (TALC) was developed by Richard W. Butler and published in 1980, and since then it has been widely used to study tourist destinations, places and attractions with the aim of identifying the stage in which a tourist area is placed, thus understanding its historical development and the possible ways in which it may develop from then. Pontal de Coruripe’s TALC was analyzed with a focus on its economic and social dimensions, since before touristification started – prior to 1985 – up until when this study implemented, in 2015. The research was developed as a case study using a qualitative methodological approach. Data collection used a semi-structured interview schedule which was run with hotel managers as well as observation, a photographic survey and document perusal. Results present the historical development of the offer of hotel rooms in Pontal de Coruripe, the characteristics of its TALC, as well as the expectations as to how tourism may develop into the future in this community.

The study was to assess on corporate governance and risk management in Tanzania. The study was guided by three objectives which were to assess if transparency, disclosure and audit have significant effect on risk management of the firm, to assess if the board of directors have significant effect on risk management of the firm and evaluate if the ownership structure have significant effect on risk management of the firm. Furthermore, we assess how corporate governance and particularly board of directors, ownership structure, transparency disclosure and audit can affect risk management practices in the context of Dar es Salaam stock exchange listed banks. By the use of a content in analysis approach, the level of exposing the risks in terms of likelihood, consequences of such risk and the strategies used for managing that risk were identified for each kind of risk by using attributes. The results show that corporate governance is related to board of directors, ownership structure, transparency, disclosure and audit play a positive significant and crucial role in establishing an integrative risk management approach. The results from data collected demonstrate that corporate governance has positive significant effect in determining the the good quality of risk management through the level of risk-taking in decisions, especially in terms of financial risks management.
