Recently, 9,10-anthraquinone (AQ) contamination in Chinese Liupao tea has attracted much attention because the tea for export must meet the EU limit (10 µg kg−1). In this study, a method was developed in which the sample was extracted with n-hexane-acetone solution, then purified with Florisil adsorbent, detected by GC-MS/MS and contamination levels of AQ determined using an internal standard. This method was found to be more suitable for Liupao tea and other dark tea complex substrates than the QuEChERS procedure. The sample pre-treatment method was optimized with respect to extraction reagent and clean-up column adsorbent and n-hexane-acetone selected as the optimal extraction solvent. When the content of Florisil in the column was 1.0 g, the optimum clean-up was achieved. The new method reduced the limit of quantification (LOQ) of AQ to 10 μg kg−1, and accuracy was also further improved. The recovery of AQ-fortified tea samples containing 20–100 µg·kg−1 was 94.5–100.4%, and the relative standard deviation (RSD) was less than 1.3%. In a small survey, 98 Liupao tea samples on the market were tested by the new method. It was found that 61 samples were positive (occurrence rate 63.3%), and thus exceeded the EU limit (10 µg kg−1). This study also found that the contamination of AQ in Liupao tea increased with the length of ageing. The source of AQ in the Liupao tea ageing process will be the focus of further research.

Farmers are disproportionally affected by depression and suicide. Social connectedness has been shown to reduce depression and suicide among the general population but its impact on farmers is less well-known. Our previous research indicated that farmers who had cooperative resources and social support reported decreased symptoms of depression. However, it was unclear whether farmers who were not cooperative members or utilized resources from non-cooperative organizations differed from cooperative farmers in mental health. A survey consisted of online self-completion and phone interviews was conducted among 307 participants (197 co-op, 110 non-co-op) to examine whether Midwest (north central United States) cooperative and non-cooperative farmers differ in perceived stress and symptoms of depression and whether potential differences were impacted by program use, program satisfaction, and social support. Cooperative farmers reported lower perceived stress and symptoms of depression than non-cooperative farmers and the difference was statistically significant for perceived stress. Use of educational programs, such as training and mentorship, was associated with decreased perceived stress but not symptoms of depression. Satisfaction with programs and social support were associated with decreased perceived stress and symptoms of depression. Program satisfaction was observed to have more associations with decreased perceived stress and symptoms of depression than program use. Results reveal that organizational resources and social support can mitigate mental health risks among farmers. This study highlighted an opportunity for future investigation of social connectedness in addressing farmers' mental health. [ABSTRACT FROM AUTHOR]

Agricultural cooperatives are formed to promote farmers' economic, social, and legislative interests. Their role in influencing mental health is less known. We characterized farmers' experiences with cooperatives and identified the potential impact of cooperatives in promoting mental health. Semi-structured interviews were conducted in Wisconsin with 12 participants, including farmers, cooperative professionals, and agricultural extension educators. Participants were asked about stress among farmers; cooperative structures and services provided to farmers, and farmers' interactions with the cooperatives; and the role cooperatives play in reducing stress among farmers. Three main themes were developed: stress farmers were experiencing, available resources from cooperatives, and the role of cooperatives in promoting farmers' mental health. Stress farmers were experiencing was elucidated through the subthemes: increased stress, depression, and suicide and stressors involving finances, occupational pressure, relationships, isolation, and loneliness. Available resources from cooperatives were described in subthemes: cooperative characteristics, services, and engagement activities. The role of cooperatives in promoting farmers' mental health was discussed through subthemes: responder, community, facilitator, and divergent views on whether co-ops can protect farmers' mental health. Cooperatives provide members market stability, services, and opportunities for decision-making, social interaction, and civic engagement. These resources create a community where farmers feel a sense of belonging and retain a level of control. As rural communities continue to struggle with mental health resource shortages, identifying and evaluating community-based resources such as those offered by the cooperatives is imperative.

Strategy, management, corporate social responsibility, critical accounting, and other business researchers frequently utilize financial metrics such as return on assets, return on equity, and return on sales as proxy measures for the financial performance of firms. Large data sets offer convenience but exclude the textual data of corporate disclosures that offers critical insight into specific executive actions and social and environmental outcomes. This study looks at the detrimental consequences of the prevalent practice of relying on macrofinancial metrics as measures of firm performance. Insight from the socioeconomic approach to management (SEAM) is then applied to help an external analyst develop the perspective of an internal consultant to identify hidden costs in corporate disclosures. An extensive case on former CEO Robert Nardelli's tenure at Home Depot is presented as an example of applied SEAM theory to explore how a causal network of dysfunctions can be traced through publicly available financial disclosures. The management discussion and analysis as well as the executive incentive compensation formulas serve as a roadmap to discover hidden costs. The study offers a critical perspective of financial disclosures to allow researchers to externally diagnose dysfunctions sooner rather than years later, an insight formerly only available to internal consultants.
