The publication Corporate Fraud and Internal Control contains essential guidance for companies to examine and improve their fraud programs: Corporate governance legislation has become increasingly concerned with the ongoing resilience of organizations and, particularly, with their ability to resist corporate fraud from the lowest levels to the upper echelons of executive management. It has become unacceptable for those responsible for corporate governance to claim, "I didn't know". Corporate Fraud and Internal Control focuses on the appropriateness of the design of the system of internal controls in fraud risk mitigation, as well as the mechanisms to ensure effective implementation and monitoring on an ongoing basis.

Just how influential is rainfall on agricultural production in the Sudan-Sahel of Africa? And, is there evidence that support for small-scale farming can reduce the vulnerability of crop yields to rainfall in these sensitive agro-ecological zones? These questions are explored based on a case study from Cameroon’s Sudan-Sahel region. Climate data for 20 years and crop production data for six major food crops for the same years are used to find patterns of correlation over this time period. Results show a distinction of three periods of climatic influence of agriculture: one period before 1989, another between 1990 and 1999 and the last from 2000 to 2004. The analysis reveals that, while important in setting the enabling biophysical environment for food crop cultivation, the influence of rainfall in agriculture can be diluted by proactive policies that support food production. Proactive policies also reduce the impact of agriculturally relevant climatic shocks, such as droughts on food crop yields over the time-series. These findings emphasize the extent of vulnerability of food crop production to rainfall variations among small-holder farmers in these agro-ecological zones and reinforce the call for the proactive engagement of relevant institutions and support services in assisting the efforts of small-scale food producers in Africa’s Sudan-Sahel. The implications of climate variability on agriculture are discussed within the context of food security with particular reference to Africa’s Sudan-Sahel.

Water makes up most of the Earth, although just 0.3% is usable for people and animals. The huge oceans, icecaps, and other non-potable water resources make up the remaining 99.7%. Water quality has declined in recent decades due to pollution from population growth, industry, unplanned urbanization, and poor water management. The textile industry has significant global importance, although it also stands as a major contributor to wastewater generation, leading to water depletion and ecotoxicity. This issue arises from the extensive utilization of harmful chemicals, notably dyes. The main aim of this review article is to combine and assess the impacts of textile wastewater that contains dyes and chemicals, and to examine their potential consequences on human health, aquatic health, and the environment. Moreover, the dedicated section presents an in-depth review of various environmentally sustainable approaches for the management and treatment of wastewater in the textile industry. These approaches encompass bio adsorbents, biological methods, membrane technology, ion exchange, advanced oxidation processes, as well as physicochemical and biochemical processes. Furthermore, this study also evaluates the contemporary progressions in this particular domain, taking into account the corresponding advantages and disadvantages. Finally, this article highlights the significance of recovering and reusing dyes, alkalis, and electrolytes in wastewater treatment. Additionally, it emphasizes the necessity of performing technoeconomic analyses and life cycle assessments (LCA) on wastewater treatment plants.

Mining areas often experience a climate of social tension due to the potential trade-off between expected employment impact and concerns for environmental damage. We address this topic from a theoretical perspective that, unlike most empirical research, includes medium-term dynamics. We developed a two-sector dynamic model that provides a new way to identify differences among mining regions in terms of conflict risk, local development, and welfare. There are critical points in the natural-resource base of local nonmining activities and in the pollution rate of mining operations, which determine the type of dynamics and its welfare outcomes due to the opening up of the economy to mining investment. Pollution control is a sine qua non for welfare gains despite new job opportunities in the mining sector.

The rapid development of technology transforms the way researchers conduct projects, communicate with others, and disseminate findings. In addition to traditional presentations of research results, this paper argues that building a digital artifact is another optional method for the dissemination of research findings from the perspective of marketing. Thus, 20 Irish and Chinese micro-influencers were investigated from March 2016 to March 2019, and their microblogs were analyzed by text mining techniques. Consequently, the paper finds four types of keywords that micro-influencers apply to their marketing on social media. Based on the marketing keywords, a digital tool is designed to label fashion keywords in the microblogging automatically. The proposed tool not only contributes to model fashion bloggers’ content and increase the influence of marketing on social media but also enlightens marketing scholars to develop digital tools for the sustainability of disseminating research results.

Carbon dioxide hydrates were formed in fresh water and in aqueous mixtures containing ammonium sulfate, at concentrations equal to 1.9, 6.3, and 9.5 wt%. The moles of hydrates formed were compared, to define the inhibiting strength of the electrolyte solution and the dependence of inhibition from concentration. The addition of salt strongly inhibited the process and the number of hydrates produced passed from 0.204–0.256 moles, obtained in fresh water, to 0.108–0.198 moles, obtained at the lowest concentration tested. The further addition of salt still lowered the production of the hydrates; at the highest concentration tested, only 0.092–0.177 moles were obtained. The pressure-temperature evolutions of the hydrates were then discussed and compared with the ideal process and with the experimental results obtained in demineralised water. Finally, further samples of CO2 hydrates, produced in the presence of 9.5 wt% salt in the aqueous phase (corresponding to 1.5 wt% NH4+), were recovered and dissociated in a separated environment. The liquid phase, resulting from their dissociation, was subjected to spectrophotometric analyses. Its NH4+ content was measured and compared with the initial concentration in water. Therefore, it was possible to quantify the capability of the system to remove the (NH4)2SO4 from the water (involved in hydrate formation) and to concentrate it in the remaining liquid phase. Considering the portion of water involved in hydrates formation, the concentration of ammonium passed from 1.5 wt% to 0.38–0.449 wt%.
