Farmer Mental Health Interventions: A Systematic Review

The prevalence of mental health disorders and suicide amongst agricultural producers is a global problem. Community leaders, researchers, policymakers, and clinicians have mobilized to develop programs to address this issue. This study reviewed a wide range of mental health interventions targeting farmer mental health spanning over 50 years and examined their reported effectiveness and constraints. A total of ninety-two articles on farmer mental health were included in a final systematic review. Most articles were written concerning mental health literacy and peer and paraprofessional support interventions in the United States and Australia. Among the 56 studies reporting empirical evaluative data, 21 were mixed-method, 20 quantitative, 11 qualitative, and 5 literature synthesis. Non-experimental, self-reported, and qualitative data suggest efficacy of mental health literacy programs, peer and paraprofessional support, and community-based and agroecological interventions. However, most interventions were not subject to rigorous evaluation and only one intervention was evaluated using a control condition. The heterogeneity of existing studies and paucity of rigorous evaluation proscribes firm conclusions related to program-type efficacy. This review demonstrates that there is still a need for a stronger and broader evidence base in the field of farmer mental health interventions, which should focus on both holistic, multi-component programs and targeted approaches.

Comprehensive Assessment of the Dynamics of Banana Chilling Injury by Advanced Optical Techniques

Green-ripe banana fruit are sensitive to chilling injury (CI) and, thus, prone to postharvest quality losses. Early detection of CI facilitates quality maintenance and extends shelf life. CI affects all metabolic levels, with membranes and, consequently, photosynthesis being primary targets. Optical techniques such as chlorophyll a fluorescence analysis (CFA) and spectroscopy are promising tools to evaluate CI effects in photosynthetically active produce. Results obtained on bananas are, however, largely equivocal. This results from the lack of a rigorous evaluation of chilling impacts on the various aspects of photosynthesis. Continuous and modulated CFA and imaging (CFI), and VIS remission spectroscopy (VRS) were concomitantly applied to noninvasively and comprehensively monitor photosynthetically relevant effects of low temperatures (5 °C, 10 °C, 11.5 °C and 13 °C). Detailed analyses of chilling-related variations in photosynthetic activity and photoprotection, and in contents of relevant pigments in green-ripe bananas, helped to better understand the physiological changes occurring during CI, highlighting that distinct CFA and VRS parameters comprehensively reflect various effects of chilling on fruit photosynthesis. They revealed why not all CFA parameters can be applied meaningfully for early detection of chilling effects. This study provides relevant requisites for improving CI monitoring and prediction.

Priming Numbas for formative assessment in a first-year mathematics unit

This paper outlines an initiative that involved implementing ‘Numbas’ as a computer-based tool to support mathematics learning. ‘Numbas’ was implemented within the existing learning management system at Queensland University of Technology, where students engaged in formative assessment activities independently and were provided with automated feedback along the way. An initial evaluation was undertaken by learning designers using the ‘Assessment Design Decisions Framework’, and although more rigorous evaluation is underway, results indicate positive outcomes, and appropriate adjustment is likely to be made before rolling it out to other units within the School of Mathematical Sciences. This paper will be of interest to other educators looking for ways to embed independent computer-aided learning of mathematics.

The making of child and adolescent psychiatrists in Australia and New Zealand

Child and adolescent psychiatry has an opportunity to adapt alongside the advancements in medical knowledge, post-graduate training, epidemiological realities and clinical service models. Here, we are guided by the mental health needs of our community’s young and their families in our review of child and adolescent psychiatry training in Australia and New Zealand. We recognise that training must respond to clinical demand and service reform while ensuring a range of clinical and educational experiences to deliver expectable competencies in order to produce child and adolescent psychiatrists that meet the communities’ needs now and in the future. We argue that training programmes be subject to rigorous evaluation by embedding continuing cycles of improvement including regular review and international bench marking.

Free Evaluation of Evidence: Does the icc need a Law of Evidence?

The International Criminal Court appears to have adopted a sui generis legal framework which favours the oldest features of both the common law and the continental law. Historically, the common law and continental legal systems have conceived questions of evidence and proof differently. Therefore, modes of judicial thinking are also different. The continental approach in the Bemba case freely evaluated the evidence. The common law approach evaluated the evidence against the burden of proof. Even though free evaluation may assist the truth-seeking mission of the Court on admissibility, the decision at the end of the trial requires rigorous evaluation only against the burden of proof. The common law of evidence provides a judicial thinking process for evaluating evidence, but free evaluation does not. This paper addresses whether the icc should develop its own evidence law to provide a route of rigorous judicial thinking when weighing evidence at the deliberation phase.

Evaluation of a Public Technology-Based Traffic Enforcement Program

While police enforcement is a well-known means of reducing traffic violations, it is also recognized that other agents should be involved in creating sustainable deterrence. This paper describes and evaluates the Israeli Road Guards program, a new and unique type of traffic enforcement, which enables simple technology-based enforcement of traffic violations by citizens. In its 24 months of operation, more than 3400 volunteers who submitted over 64,000 violation reports were involved in this program. Each report went through a rigorous evaluation process. More than 80% of the submitted reports were rejected in the various stages of the procedure. In 13.7% of the cases a notice letter was sent, and in 4.3% of cases (reflecting the most severe offenses) a citation was issued by the police. The monthly rate of report submission by the volunteers was at its highest initially, then decreased and stabilized after about six months at 1.4 reports per month. The proportion of active volunteers also decreased over time to a level of 0.26 at the end of the study period. The violation types reported within the program differed substantially from those captured by police enforcement. These differences are likely due to the manner in which each mode of enforcement was performed. The most common violations reported by volunteers were lane deviations, red light running and driving on the roads’ shoulders, which are easily documented by means of video recordings. They are also associated with higher crash risks. Thus, the results show that such public technology-based traffic enforcement, which can be carried out during regular daily driving and does not require anyone to make extra trips, may efficiently complement traditional police enforcement.

Assessment of mHealth Solutions Applied to Fall Detection for the Elderly

Mobile Health has been increasingly present in healthcare due to the wide availability of applications for smartphones, however, robust assessment methods must be considered, seeking to provide evidence for clinical practice and mHealth solutions. This research presents the assessment of applications aimed at detecting and preventing falls for the elderly, available for Android and IOS, through the Mobile App Rating Scale. Based on the results presented, it can be concluded that the fall detection and prevention applications for the elderly available for Android and IOS showed good quality after rigorous evaluation.

Extended Pre-Processing Pipeline For Text Classification: On the Role of Meta-Features, Sparsification and Selective Sampling

Pipelines for Text Classification are sequences of tasks needed to be performed to classify documents. The pre-processing phase of these pipelines involves different ways of manipulating documents for the learning phase. This Master Thesis introduces three new steps into the traditional pre-processing phase: 1) Meta-Features Generation; 2) Sparsification; and 3) Selective Sampling. Our experimental results, based on more than 5.600 measurements, show that our proposal can achieve significant gains in effectiveness when compared to the traditional TF-IDF representation (up to 52%) and word embeddings (up to 46%), at a much lower cost (9.7x faster). Our Master Thesis also includes a thorough and rigorous evaluation of the trade-offs between cost and effectiveness associated with the introduction of these new steps into the pipeline, as well as a comprehensive comparative experimental evaluation of many alternatives. This thesis falls under the topics of (i) Document Management and Classification, (ii) Information Retrieval Models and Techniques, (iii) and Text Database of the SBBD Call for Papers.

Imperfections of Scalar Approximation in Calibration of Computer-Generated Holograms for Optical Surface Measurements

Computer-generated hologram (CGH) null correctors are used as accuracy standards for interferometric measurements of optical surfaces and optical systems. Diffractive optics calibrators (DOCs) have been developed to evaluate the phase tolerance of CGHs based on scalar approximation by measuring variations in duty cycle and etching depth. However, if the grating period of a CGH < 5 λ, the scalar approximation is not accurate for phase analysis and reconstruction. In this study, the measurement errors of DOCs with small-period CGHs were investigated and experimentally verified. Results show that the imperfections of scalar approximation in CGHs cannot be ignored and the development of rigorous evaluation methods to improve the measurement accuracy of CGHs is of great practical significance.

CD276 is an important player in macrophage recruitment into the tumor and an upstream regulator for PAI-1

More than 70% of colorectal, prostate, ovarian, pancreatic and breast cancer specimens show expression of CD276 (B7–H3), a potential immune checkpoint family member. Several studies have shown that high CD276 expression in cancer cells correlates with a poor clinical prognosis. This has been associated with the presence of lower tumor infiltrating leukocytes. Among those, tumor-associated macrophages can comprise up to 50% of the tumor mass and are thought to support tumor growth through various mechanisms. However, a lack of information on CD276 function and interaction partner(s) impedes rigorous evaluation of CD276 as a therapeutic target in oncology. Therefore, we aimed to understand the relevance of CD276 in tumor-macrophage interaction by employing a 3D spheroid coculture system with human cells. Our data show a role for tumor-expressed CD276 on the macrophage recruitment into the tumor spheroid, and also in regulation of the extracellular matrix modulator PAI-1. Furthermore, our experiments focusing on macrophage-expressed CD276 suggest that the antibody-dependent CD276 engagement triggers predominantly inhibitory signaling networks in human macrophages.
