The Change Agent of the Fishermen Development Area Staff of the Fisheries Development Authority of Malaysia

This study was conducted primarily to assess the change agent roles of the Fishermen Development Area (FDA) staff of the Fisheries Development Authority of Malaysia (LKIM). Data for this study were gathered from 59 FDA frontline officers from five selected FDAs through group self-administered questionnaires and drop-and-collect data collection method. The study revealed that majority of the respondents were 30 years old and below; majority of them completed the Cambridge Overseas School Certificate/Malaysian School Certificate; nine were Diploma and Bachelor's Degree holders and majority of them joined LKIM without any working experience. With regard to role performance of the FDA staff contacted, the study revealed that almost all of the respondents did not consider work planning as part of their responsibility; more than three-fourths consulted their state supervisors as need arises; more respondents were dissatisfied than satisfied with their job; and slightly more than three-fourths of the respondents had linkage with staff from other agencies (mainly through meetings/conferences/workshops attended). Both the assistant development officers and the development assistants found it either very difficult or not difficult at all working with the fishermen. The managers were very certain of their felt difficulties both in working with the fishermen and with colleagues/supervisors and staff from other agencies. Generally, there seemed to be lack of clear understanding of change agent's role among the respondents. Based on selected personal characteristics, the mental and experiential preparation of the staff seemed to be inadequate for the officers to carry rut their expected change agent roles. Further preparation is needed for IKIM to help its staff to be more process-oriented

Biocontrol of root and crown rot in tomatoes under greenhouse conditions using Trichoderma harzianum and Paenibacillus lentimorbus. Additional effect of solarization

Indexación: ScieloTrichoderma harzianum 650 (Th650) and Paenebacillus lentimorbus 629 (Pl629) selected earlier for their ability to control Rhizoctonia solani, Fusarium solani and F. oxysporum in vitro, were applied alone or combined with solarization (summer assay) and/or with methyl bromide (MeBr) (summer and winter assays) to a soil with a high inoculum level, for the control of tomato root rot caused by the complex F. oxysporum f. sp. lycopersici - Pyrenochaeta lycopersici - Rhizoctonia solani. Evaluations were also performed independently for root damage caused by P. lycopersici, and also for R. solani in the summer assay. MeBr decreased tomato root damage caused by the complex from 88.7% to 21.2% and from 78.4% to 35.7% in the summer and in the winter assay, respectively. None of the bio-controllers could replace MeBr in the winter assay, but Th650 and Pl629 reduced root damage caused by this complex in the summer assay. Treatments with bio-controllers were improved by their combination with solarization in this season. Independent evaluations showed that the positive control of Th650 towards R. solani and the lack of effect on P. lycopersici correlates well with the endochitinase pattern expressed by Th650 in response to these phytopathogens. Root damage caused by R. solani can be controlled at a similar level as it does MeBr in summer assays, thus representing an alternative to the use of this chemical fungicide for the control of this phytopathogen.Financial support: Fondecyt 1990785

Bridging user and provider perspectives: Family planning access and utilization in rural Mozambique

Objectives: To examine how the contraceptive behavior of women in rural southern Mozambique is shaped by their individual and household characteristics; community characteristics; access to family planning services; and characteristics of health facilities.<p></p> Methods: Quantitative and qualitative data were collected mostly between January 20 and December 15, 2011, in rural areas of four districts in Gaza Province, Mozambique. The data included: a retrospective household-based survey of women of reproductive age (the analytical sample consisted of 1554 non-pregnant women in marital union); qualitative interviews with a subsample of surveyed women; a survey of communities where the women resided (n = 56); and a survey of all health facilities in the study area (n = 56). Binomial and multinomial logistic models were fitted to predict current use of modern contraceptive methods. Statistical analyses were complemented by insights from qualitative data.<p></p> Results: Positive associations were detected between contraceptive use and education, household wealth, and perceived HIV infection status. Distance to the clinic was negatively associated with contraceptive use. These effects were additive, with some varying by type of contraceptive method. Examination of qualitative data highlighted frequent cognitive dissonance between service providers and users.<p></p> Conclusion: A simultaneous consideration of user-level and provider-level perspectives on contraceptive use improves our understanding of contraceptive dynamics and can usefully inform policy

Axon diversity of lamina I local-circuit neurons in the lumbar spinal cord

Spinal lamina I is a key area for relaying and integrating information from nociceptive primary afferents with various other sources of inputs. Although lamina I projection neurons have been intensively studied, much less attention has been given to local-circuit neurons (LCNs), which form the majority of the lamina I neuronal population. In this work the infrared light-emitting diode oblique illumination technique was used to visualize and label LCNs, allowing reconstruction and analysis of their dendritic and extensive axonal trees. We show that the majority of lamina I neurons with locally branching axons fall into the multipolar (with ventrally protruding dendrites) and flattened (dendrites limited to lamina I) somatodendritic categories. Analysis of their axons revealed that the initial myelinated part gives rise to several unmyelinated small-diameter branches that have a high number of densely packed, large varicosities and an extensive rostrocaudal (two or three segments), mediolateral, and dorsoventral (reaching laminae III–IV) distribution. The extent of the axon and the occasional presence of long, solitary branches suggest that LCNs may also form short and long propriospinal connections. We also found that the distribution of axon varicosities and terminal field locations show substantial heterogeneity and that a substantial portion of LCNs is inhibitory. Our observations indicate that LCNs of lamina I form intersegmental as well as interlaminar connections and may govern large numbers of neurons, providing anatomical substrate for rostrocaudal “processing units” in the dorsal horn

The Relation between the Radial Temperature Profile in the Chromosphere and the Solar Spectrum at Centimeter, Millimeter, Sub-millimeter, and Infrared Wavelengths

Solar observations from millimeter to ultraviolet wavelengths show that there is a temperature minimum between photosphere and chromosphere. Analysis based on semi-empirical models locate this point at about 500 km over the photosphere. The consistency of these models has been tested by means of millimeter to infrared observations. In the present work, we show that variations of the theoretical radial temperature profile near the temperature minimum impacts the brightness temperature at centimeter, submillimeter, and infrared wavelengths, but the millimeter wavelength emission remains unchanged. We found a region between 500 and 1000 km over the photosphere that remains hidden to observations at the frequencies under study in this work.Comment: Accepted in Solar Physic

Enhanced teleoperation interfaces for multi-second latency conditions: System design and evaluation

Adding human cognitive skills to planetary exploration through remote teleoperation can lead to more effective and valuable scientific data acquisition. Still, even small amounts of latency can significantly affect real-time operations, often leading to compromised robot safety, goal overshoot, and high levels of human mental fatigue and cognitive workload. Thus, novel operational strategies are necessary to cope with these effects. This paper proposes three augmented teleoperation interfaces that allow the user to operate a robot subject to 3 seconds of latency: (1) Avatar-Aided Interface (AAI), a semi-autonomous approach based on a virtual element; (2) Predictive Interface (PI), an approach with direct control and predictive elements; and (3) Hybrid Interface (HI), where the operator can easily switch between PI and AAI. We conducted a systematic within-subject experiment to evaluate the proposed interfaces in a realistic virtual environment with frequent traction losses. The user study compared AAI and PI to a Control Interface (CI), which did not display any augmented elements. The main results of this comparison showed that: (1) AAI led to a significant reduction in workload and a significant increase in usability and robot safety; (2) the use of the PI caused a significant increase in path length, indicating that operators overshoot their goals more often with this approach; (3) PI and AAI had lower reported effort; and (4) AAI is more flexible and effortless than PI and CI. Finally, the presented results show the need to consider uncertainty (e.g., traction loss) in future interface design.info:eu-repo/semantics/publishedVersio

From Pandemic to Pedagogy: Teaching the Technology of Lawyering in Law Clinics

The COVID-19 pandemic has transformed the nation’s approach to work and learning. Law schools, law firms, courts, and administrative agencies abruptly closed their offices and quickly reimagined how to perform their daily functions remotely. Many of these institutions have plans to maintain aspects of remote operations and services post-pandemic. With this in mind, the authors of this Article conducted a survey of law school clinical faculty during the winter of 2021 to better understand how clinicians pivoted their instruction and practice using technology during the pandemic. The authors use the survey results to show how the COVID-19 experience positions clinical programs to be leaders in answering the growing calls to incorporate technical competency into legal education. The authors draw on the experiences of clinicians during the pandemic to demonstrate how law practice technology can be deliberately and thoughtfully integrated into existing clinical pedagogy and practice. The Article concludes by urging clinicians to build on the current momentum to embrace what they call “the technology of lawyering” as an indispensable component of clinical education
