A suicide research agenda for people from immigrant and refugee backgrounds
The aim of this study was to establish mental health and suicide research priorities for people from immigrant and refugee background in Australia. This article focuses on the data relevant to the development of the suicide research agenda. This study was conducted using Delphi consensus method with two rounds of online questionnaires. A total of 138 and 86 participants, respectively, completed the first and second rounds of survey. Participants were policy makers, service providers, academics, service users, and carer advocates in Australia with expertise in mental health and/or suicide among people from immigrant and refugee backgrounds. Of the total 268 research questions included in the questionnaires, 70 questions about suicide were ranked as essential by over 50% respondents (i.e., the set level of consensus). In particular, research questions regarded as the greatest priority related to access and engagement with suicide prevention services, suicide protective and risk factors compared to populations not from immigrant and refugee backgrounds, and culturally appropriate assessment of suicide risk
Maximizing Performance in Human Powered Vehicles: A Literature Review and Directions for Future Research
If the limits of performance in human powered vehicles (HPV) are to be reached, designers of HPVs need to understand how the body interacts with the vehicle to maximize propulsive forces, and how the vehicle interacts with the environment to minimize resistive forces. This paper will review, compare and summarize the various research literature on both upright and recumbent cycling positions regarding how systematic changes in external mechanical variables (seat-tube-angle, seat-to-pedal distance, crank arm length) interact with internal biomechanical factors (hip, knee, and ankle angles) to affect power production and cycling performance. Conclusions for future research will also be also presented
The Biomechanics of Force and Power Production in Human Powered Vehicles
There are a large number of factors affecting performance in human powered vehicles (HPV). Designers of HPV\u27s often focus on how resistive forces (friction, drag) can be minimized, as opposed to how propulsive forces can be maximized. How to maximize propulsive forces through vehicle design is not often understood because of a complex interaction between internal biomechanical factors (muscle force/torque/power production) and external mechanical factors (e.g., seat-to-pedal distance, crank arm length, seat-tube angle, backrest angle, chain wheel size). The purpose of this paper is two-fold: (1) to provide information, from a biomechanical and physiological perspective, how muscle force is produced and modified; and (2) to examine how the muscle force produced interacts with external mechanical factors to produce power

EFFECT OF CHANGES IN CRANK ARM LENGTH AND LOAD ON POWER PRODUCTION IN RECUMBENT CYCLING
The purpose of this study was to determine the trend in peak power (PP), mean power (MP), and minimum power (MINP) with changes in load when cycling in a recumbent position. Fifteen female participants were randomly assigned to one of three crank arm length (CAL) conditions (110, 180, or 250 mm) and tested on a Monark Cycle ergometer with 5 loads varying from 75-165 gm/kg of body mass. The Wingate Anaerobic Cycling test was performed in a recumbent position (75 seat tube angle, backrest perpendicular to the ground). Curve estimation with regression analysis on incrementing loads revealed: (1) a quadratic trend in PP; (2) a quadratic trend in MP and MINP for the 110 and 180 mm CAL; and (3) a linear trend in MP and MINP for the 250 mm CAL. These trends suggest there is an optimal load for different CALs to maximize power production

Operational Research Project Management, Experiences, Challenges and Lessons Learnt
Introduction: Effective project management revolves around Strategic Management. Logistics seem simple and straight forward but, often the role it plays in scientific undertakings is overlooked. It is usually assumed that research starts and ends in the laboratory. It is a fact that, for research activities to be successful, it requires exceptional planning to ensure that, resources are available as per the approved work-plan. This entails determination of what, when, who, why and how it is to be done. Recent studies indicate that, logistics-related activities' impact on research undertakings significantly.
Objective: To document the project management experiences and lessons learnt in coordinating and implementation of East Africa Public Health Laboratories Networking Project –Operational Research (EAPHLNP-OR) activities in five East African countries, namely: Kenya, Rwanda, Burundi, Uganda and Tanzania.
Methodology: The operational research component of the EAPHLNP, KEMRI established an OR Secretariat to coordinate the project activities in Kenya and provide leadership to regional principal investigators. In consultation with the project Secretariat, the role of the administrator involved Work plan and budget preparation, planning, organizing, communicating, coordinating local and regional meetings, linking KEMRI research team with the study site (Hospital Administration) and Research Teams in the various counties. The site Teams obtained informed consent, recruited respondents, collected specimens, analyzed the specimens and shipped a portion of the same together with the results to KEMRI.
Key Activities Of The Project: Managing financial aspects (budget and financial report preparations), logistical coordination, and procurement of training materials, organizing for meeting venues, taking minutes, travel arrangements and participation in scientific report writing. Control mechanism such as dairies, ledger books, work plan charts and schedules, managing and monitoring the progress of the project activities.
Lesson Learnt & Challenges: Interpersonal skills were essential at all stages of the project. The critical stage was the forming, storming, and norming stages. Here, group dynamics and conflicts took center stage. This threatened to stall the OR Project. Timely and constant communication with the study site coordinators, prioritization of scheduled project activities, was essential. Ensuring all parties are kept informed on the progress of the OR activities. The information in user-friendly format dairies and schedules provided the necessary feedback at administrative level, on project performance and at research findings. Key challenges included fluctuating funding, group dynamic conflicts and staff transfers.
Discussion: EAPHLNP-OR was a Seven (7) years project undertaking, which for effective management involved understanding of the operating environment, strategic planning for short and long term goals, constant communication, review of priorities, documentation and practise of goodinterpersonal skills.
Conclusion: Successful project management in OR required an administrator to coordinate the utilization of the available resources both capital and human. This is the second supplement in this issue only aspects on findings from TB and Enteric studies done in Kenya have been addressed.Three regional policy briefs on TB Enteric and malaria have been included
Stratification of persons with diabetes into risk categories for foot ulceration
Background: Patients with diabetes mellitus are at a higher risk of lower extremity complications as compared to their non-diabetic counterparts.Objective: To study risk factors for diabetic foot ulcer disease and stratify patients with diabetes into risk categories for foot ulceration.Design: Cross-sectional descriptive study over five months period.Setting: Diabetic outpatient clinic, at the Kenyatta National Hospital.Subjects: Two hundred and eighteen ambulatory subjects with diabetes mellitus without active foot lesions.Results: The prevalence of previous foot ulceration was 16% while that of previous amputation was 8%. Neuropathy was present in 42% of the study subjects and was significantly associated with age, male gender, duration of diabetes, random blood sugar, systolic blood pressure and the presence of foot deformity. Peripheral arterial disease was present in 12% and showed significant association with male gender. Foot deformities were observed in 46% of study subjects and were significantly associated with age, male gender, and presence of neuropathy. Subsequently 57% were categorised into IWGDF group 0 - no neuropathy, 10% were placed in group 1- neuropathy alone, 16% were put in group 2 - neuropathy plus either peripheral arterial disease or foot deformity and 17% were placed in risk group 3 - previous foot ulceration/amputation.Conclusion: More than one third (33%) of diabetic patients were found to be at high risk for future foot ulceration (lWGDF groups 2 and 3). Published evidence exists that shows improved outcomes with interventions targeting individual patients with diabetes at high-risk of foot ulceration. Long term prospective studies to determine outcomes for the different risk categories should be carried out locally
Diversity and systematics of Haminoeidae gastropods (Heterobranchia: Cephalaspidea) in the tropical West Pacific Ocean: New data on the genera Aliculastrum, Atys, Diniatys and Liloa
Four genera of Haminoeidae gastropods inhabiting the tropical West Pacific (Aliculastrum, Atys, Diniatys, and Liloa) were studied based on the combined analyses of live animals, external morphology, anatomy and shells aided by scanning electron microscopy and molecular sequencing. Eleven species are described including two new to Science, namely Atys pittmani sp. nov. and Atys ukulele sp. nov.. The putative synapomorphies of the genera Aliculastrum, Diniatys, and Liloa are discussed. High levels of morpho-anatomical variability were found among representatives of the genus Atys, which hampered the recognition of synapomorphies.publishedVersio
