'The Black Knights of Fortune': A Study of the Zappo-Zap and Euro-African Encounters in the Late Nineteenth-Century Kasai

Recent popular publications have emphasised the brutality and suffering inflicted upon African communities at the onset of colonialism in the Congo, under the Belgium King Leopold II. Yet this Euro-centric approach works to obscure African agency and collaboration under the Congo Free State, and the dependency of the Free State officers upon their African partners. Through following the trajectory of the Zappo-Zap, a distinctly under-studied slaving ethnic group who migrated to the western Kasai region, this dissertation makes a headway into understanding that the violence of the Congo Free State was fabricated from existing modes of exploitation in the Congo prior to European penetration, such as the Arab-Swahili commercial empires. Notably loyal, the example of the Zappo-Zap serves to evaluate the role of African agents in the shaping of exploitative Free State policies, and elucidates the extent that the Zappo-Zap adapted to, and gained from, the reliance of the Free State on them, in the midst of numerous rebellions in the Kasai such as the infamous Luluabourg Revolt

Analysis of Population Structure in a California Newt (Taricha torosa) Metapopulation

As anthropogenic influences take an ever-increasing toll on the environment, understanding how environmental change affects species is paramount. Concern regarding decline in amphibian populations has spurred research examining the effects of habitat change on the dynamics of populations at landscape levels. One important goal is to understand how gene flow among populations is affected by changes in habitat. Biologists need to consider the relationship between gene flow and habitat alterations so that movements among individual breeding ponds can be maintained over time, reducing risk of local extinction events. This study focuses on patterns of gene flow among thirteen populations of California newt (Taricha torosa). We examined genetic structure using five microsatellite markers. We found little evidence of genetic structure on the studied landscape despite extensive variation at our microsatellite loci. Support for models of population structure was weak, and estimates of gene flow among population pairs were high, suggesting that interpond movements on this landscape are extensive. These findings are contrary to our expectations and deviate from other work on these landscapes for other species. Further analyses are required to determine the scale at which we would observe a pattern of genetic structure in this species, but ultimately, these data will be informative for conservation efforts directed at the California Newt

Implementing food pantry nutrition policies: Perspectives from the field

The charitable food system includes food pantries and are often used by individuals and households who are food insecure (Kuhns & Norotny, 2021; Seligman & Berkowitz, 2019; Sangye, 2013). Adults with any level of food insecurity have a 43% to 53% greater risk of developing a chronic disease than those who are food secure. Those who are food secure have a 37% risk of developing a chronic disease (Gregory & Coleman-Jenson, 2017). For this reason, efforts are being made from state and federal levels to focus on nutrition security, rather than only food security, by increasing the percentage of nutrient dense foods being distributed through food pantries. These efforts are in the form of nutrition policies to establish uniform dietary guidelines, nutrition and health literacy education, and investments toward the capacities necessary to store healthy foods, such as fresh fruits and vegetables (Seligman et al., 2020). However, little attention has been given to directors and whether they have the necessary resources, support, and training to implement such nutrition policies. Research is needed to understand if implementing nutrition policies puts a strain on directors who are already limited on time and resources because they are fulfilling the leadership roles of their organization as the business manager, volunteer organizer, and social services provider (Jones & Deitrick, 2018; Precious et al., 2017). The purpose of this case study is to capture the experiences of food pantry and food bank directors while implementing nutrition policies within the Arkansas Delta Region. During a time when food pantry usage rates are on the rise (Chapman, 2017; Sangye, 2013; Wright, 2018), it is imperative research be expanded to explore the effect implementing nutrition policies are having on directors. It is the researcher’s hope to bring understanding to those who are not on the front lines of charitable food distribution so future processes can be developed to make implementation easier

Individual Control of Risk: Seat Belt Use, Subjective Norms and the Theory of Reasoned Action

When faced with a risk for which an inexpensive solution is available, individuals often choose the risk rather than the solution. Protection from certain kinds of risks, e.g., using seat belts or condoms or insulating against radon, is largely under personal control, but individuals often choose not to comply with behaviors which would reduce the risk. The Theory of Reasoned Action (TRA) has been used to predict when individuals will comply. The authors attempted to validate aspects of the TRA by the use of scenarios. Factor analysis of their data supports the theory that intention is a major determinate of behavior but fails to establish the influence of scenarios on subjects\u27 intention to wear seat belts

Perspectives of healthcare providers on the nutritional management of patients on haemodialysis in Australia: An interview study

Objective To describe the perspectives of healthcare providers on the nutritional management of patients on haemodialysis, which may inform strategies for improving patient-centred nutritional care. Design Face-to-face semistructured interviews were conducted until data saturation, and thematic analysis based on principles of grounded theory. Setting 21 haemodialysis centres across Australia. Participants 42 haemodialysis clinicians (nephrologists and nephrology trainees (15), nurses (12) and dietitians (15)) were purposively sampled to obtain a range of demographic characteristics and clinical experiences. Results Six themes were identified: responding to changing clinical status (individualising strategies to patient needs, prioritising acute events, adapting guidelines), integrating patient circumstances (assimilating life priorities, access and affordability), delineating specialty roles in collaborative structures (shared and cohesive care, pivotal role of dietary expertise, facilitating access to nutritional care, perpetuating conflicting advice and patient confusion, devaluing nutritional specialty), empowerment for behaviour change (enabling comprehension of complexities, building autonomy and ownership, developing self-efficacy through engagement, tailoring self-management strategies), initiating and sustaining motivation (encountering motivational hurdles, empathy for confronting life changes, fostering non-judgemental relationships, emphasising symptomatic and tangible benefits, harnessing support networks), and organisational and staffing barriers (staffing shortfalls, readdressing system inefficiencies). Conclusions Organisational support with collaborative multidisciplinary teams and individualised patient care were seen as necessary for developing positive patient-clinician relationships, delivering consistent nutrition advice, and building and sustaining patient motivation to enable change in dietary behaviour. Improving service delivery and developing and delivering targeted, multifaceted self-management interventions may enhance current nutritional management of patients on haemodialysis

Functional Genomics Profiling of Bladder Urothelial Carcinoma MicroRNAome as a Potential Biomarker.

Though bladder urothelial carcinoma is the most common form of bladder cancer, advances in its diagnosis and treatment have been modest in the past few decades. To evaluate miRNAs as putative disease markers for bladder urothelial carcinoma, this study develops a process to identify dysregulated miRNAs in cancer patients and potentially stratify patients based on the association of their microRNAome phenotype to genomic alterations. Using RNA sequencing data for 409 patients from the Cancer Genome Atlas, we examined miRNA differential expression between cancer and normal tissues and associated differentially expressed miRNAs with patient survival and clinical variables. We then correlated miRNA expressions with genomic alterations using the Wilcoxon test and REVEALER. We found a panel of six miRNAs dysregulated in bladder cancer and exhibited correlations to patient survival. We also performed differential expression analysis and clinical variable correlations to identify miRNAs associated with tobacco smoking, the most important risk factor for bladder cancer. Two miRNAs, miR-323a and miR-431, were differentially expressed in smoking patients compared to nonsmoking patients and were associated with primary tumor size. Functional studies of these miRNAs and the genomic features we identified for potential stratification may reveal underlying mechanisms of bladder cancer carcinogenesis and further diagnosis and treatment methods for urothelial bladder carcinoma

Calibration of Concentric Tube Continuum Robots: Automatic Alignment of Precurved Elastic Tubes

Joint level calibration is an integral part of robotics as it directly influences the achievable accuracy. As opposed to serial robotic arms, continuum robots are not composed of any rigid links or joints, but of elastic materials that undergo bending and torsion. The jointless composition requires dedicated calibration procedures. In this letter, we introduce an automatic method for aligning precurved elastic tubes for joint level calibration of concentric tube continuum robots. The robot tip is equipped with a sensor in order to track its position during calibration such that subsequent data processing can extract the rotational zero position automatically. While we present a general framework independent of the utilized sensor technology, we evaluate our approach using three different sensing methodologies, i.e. magnetic, inductive, and electromagnetic. Furthermore, we advise on properties for appropriate sensors. Our experimental results show, that the rotational home position can be found reproducibly with a minimal dispersion of 0.011°

Le contrôle d'un jet d'air rectangulaire via l'introduction de cylindres animés d'un mouvement de rotation

L'idée à l'origine de l'étude est de modifier la structure d'un écoulement pour transformer cet écoulement convectivement instable en un écoulement globalement instable. Les jets globalement instables montrent un taux d'expansion plus élevé que les jets homogènes convectivement instables. Une simulation numérique a montré que le forçage, d'un jet convectivement instable, au moyen de sources de vorticité contrôlées, conduisait à une augmentation du mélange. Notre étude vise à réaliser un montage expérimental équivalent afin de confirmer les premiers résultats observés
