Making Sense of Family Deaths in Urban Senegal: Diversities, Contexts, and Comparisons

Despite calls for cross-cultural research, Minority world perspectives still dominate death and bereavement studies, emphasizing individualized emotions and neglecting contextual diversities. In research concerned with contemporary African societies, on the other hand, death and loss are generally subsumed within concerns about AIDS or poverty, with little attention paid to the emotional and personal significance of a death. Here, we draw on interactionist sociology to present major themes from a qualitative study of family deaths in urban Senegal, theoretically framed through the duality of meanings-in-context. Such themes included family and community as support and motivation; religious beliefs and practices as frameworks for solace and (regulatory) meaning; and material circumstances as these are intrinsically bound up with emotions. Although we identify the experience of (embodied, emotional) pain as a common response across Minority and Majority worlds, we also explore significant divergencies, varying according to localized contexts and broader power dynamics

Fine Grid Numerical Solutions of Triangular Cavity Flow

Numerical solutions of 2-D steady incompressible flow inside a triangular cavity are presented. For the purpose of comparing our results with several different triangular cavity studies with different triangle geometries, a general triangle mapped onto a computational domain is considered. The Navier-Stokes equations in general curvilinear coordinates in streamfunction and vorticity formulation are numerically solved. Using a very fine grid mesh, the triangular cavity flow is solved for high Reynolds numbers. The results are compared with the numerical solutions found in the literature and also with analytical solutions as well. Detailed results are presented

Further Studies on Vibration Compaction of Cohesive Soils

The investigations described in this report are a continuation of previous work designed to determine the basic laws governing the compaction of cohesive soil by vibration. A report dated December, 1954, described the results of tests on sandy loam, while this report describes similar tests on a much more cohesive soil

Low Cost Magnetometer Calibration and Distributed Simultaneous Multipoint Ionospheric Measurements from a Sounding Rocket Platform

Low cost and low size-weight-and-power magnetometers can provide greater accessibility for distributed simultaneous measurements in the ionosphere, either onboard sounding rockets or on CubeSats. The Space and Atmospheric Instrumentation Laboratory at Embry-Riddle Aeronautical University launched a midlatitude sounding rocket named SpEED Demon from Wallops Flight Facility in August 2022. SpEED Demon has a comprehensive suite of instruments for electrodynamics and neutral dynamics measurements. Among this suite is one high performance Billingsley magnetometer (TFM65VQS) and six commercial-off-the-shelf magnetometers manufactured by the PNI Corporation (RM3100). Of the six, two PNI magnetometers are situated on a deployable boom on the main payload that also carries the Billingsley magnetometer. The remaining four PNI magnetometers are distributed among four ejectable subpayloads. These low-cost and low SWaP magnetometers can achieve a resolution of approximately 1.5 nT and a precision of +/- 4 nT (one sigma) at 15 Hz in a uniform magnetic field. This performance is sufficient for detecting and measuring field aligned currents as well as a variety of other geomagnetic disturbances. The magnetometers are calibrated against an independently calibrated flux-gate magnetometer inside a Helmholtz cage. Zero field offsets are quantified inside a triple-layer mu-metal zero gauss chamber. This work will present the calibration process, the calibration results, and the flight performance of these sensors from the SpEED Demon sounding rocket launch

Balloon Borne GPSsondes that Enable Simultaneous Multi-Point Atmospheric Sensing with a Single Ground Station

Balloon-borne radiosondes provide measurements of in-situ atmospheric data such as wind velocity, temperature, and pressure, amongst many others. The Space and Atmospheric Instrumentation Laboratory at Embry-Riddle Aeronautical University has developed low cost (\u3c $150, all inclusive) GPS-enabled radiosondes that are capable of having multiple balloons simultaneously in the air communicating to a single omni-directional ground station antenna. Each GPS-sonde is equipped with a GPS Module for zonal and meridional winds, thermistor for in-situ temperature, and a pressure sensor. Slant range of greater than 120km is achieved through low-cost LoRa radio modules. Interference-free transmission timing between multiple payloads is done by time division multiplexing. The current design allows for up to six payloads to be simultaneously airborne and transmit live atmospheric data through one ground station. A higher number of simultaneous transmissions are also possible, albeit with a minor hit to spatial resolution. We present the system design, complete with hardware and software details, as well data from our current test flights and plans for future development

Visions in monochrome: Families, marriage and the individualisation thesis

This paper takes issue with the way in which the individualisation thesis – in which it is assumed that close relationships have become tenuous and fragile - has become so dominant in ‘new’ sociological theorising about family life. Although others have criticised this thesis, in this paper the main criticism derives from empirical research findings carried out with members of transnational families living in Britain whose values and practices do not fit easily with ideas of individualisation. It is argued that we need a much more complex and less linear notion of how families change across generations and in time

Refining tree recruitment models

We used a micrometeorological dispersal model to simulate seed and seedling distributions derived from subcanopy balsam fir (Abies balsamea (L.) Mill.) source trees in a trembling aspen (Populus tremuloides Michx.) dominated forest. Our first objective was to determine the effect of substituting basal area for cone production as a proxy for seed output. The results showed that the r2 from the regression of predicted versus observed densities increased by ∼5% for seeds and ∼15% for seedling simulations. Our second objective was to determine the effects of changing the median horizontal wind speed. The median speed in this forest environment varies according to the proportion of leaves abscised. For values of the median expected wind speed between the extremes of leafless and full-canopy forests, the r2 of predicted versus observed varied between 0.35 and 0.49 for seeds and between 0.33 and 0.62 for seedling simulations. We demonstrated that the simple one-dimensional model can have added precision if the dispersal parameters are chosen so as to allow more fine-scale variation

Family Trouble: Heteronormativity, emotion work and queer youth mental health

Conflict with the family about sexual orientation and gender diversity is a key risk factor associated with poor mental health in youth populations. Findings presented here derive from a UK study that employed an interdisciplinary critical mental health approach that de-pathologized emotional distress and conceptualised families as social and affective units that are created through everyday practices. Our aim was to explore how family relationships foster, maintain or harm the mental health and wellbeing of LGBTQ+ youth. Data were generated through exploratory visual, creative and digital qualitative methods in two phases. Phase 1 involved digital/paper emotion maps and interviews with LGBTQ+ youth aged 16-25 (n=12) and family member/mentor interviews (n=7). Phase 2 employed diary methods and follow-up interviews (n=9). The data analytic strategy involved three stages: individual case analysis; cross-sectional thematic analysis; and metainterpretation. We found that family relationships impacted on queer youth mental health in complex ways that were related to the establishment of their autonomous queer selves, the desire to remain belonging to their family and the need to maintain a secure environment. The emotion work involved in navigating identity, belonging and security was made difficult because of family heteronormativity, youth autonomy and family expectations and had a stark impact on queer youth mental health and wellbeing. Improving the mental health of LGBTQ+ youth requires a much deeper understanding of the emotionality of family relationships and the difficulties negotiating these as a young person
