Objective:
Children born to mothers infected with human immunodeficiency virus (HIV) during pregnancy experience increased risk of neurocognitive impairment. In Botswana, HIV infection is common, but standardized cognitive testing is limited. The Penn Computerized Neurocognitive Battery (PennCNB) is a widely used cognitive test battery that streamlines evaluation of neurocognitive functioning. Our group translated and culturally adapted the PennCNB for use among children and adolescents in this high-burden, low-resource setting. The current study examined the construct validity and sensitivity to HIV infection and exposure of the culturally adapted PennCNB among a cohort of HIV-affected children and adolescents in Gaborone, Botswana.
Participants and Methods:628 school-aged children aged 7-17 years (n=223 children living with HIV [HIV+]; n=204 HIV exposed, uninfected [HEU]; and 201 HIV unexposed, uninfected [HUU]) completed the PennCNB. Participants were recruited from a clinic specializing in the care and treatment of HIV+ children and adolescents in Gaborone, Botswana, as well as from local schools. Confirmatory factor analyses were performed on efficiency measures for 13 PennCNB tests. Multiple regressions examined associations between HIV and neurocognitive functioning while controlling for age and sex. Multivariate normative comparisons were used to examine rates of overall cognitive impairment by comparing individual profiles of test scores to the multivariate distribution of test scores using age-normed data from the HUU group.
Results:Confirmatory factor analysis supported four hypothesized neurocognitive domains: executive functioning, episodic memory, complex cognition, and sensorimotor/processing speed. As expected, there were main effects of age on cognitive performance across all domains (ps < .001), and there were small sex differences, with females performing better in executive functioning and males performing better on visuospatial processing. Children and adolescents living with HIV performed significantly worse than HUU across all domains (ps < .001), with the largest effect sizes on measures of abstraction, working memory, and processing speed. HEU also performed worse than HUU across several domains, with smaller effect sizes. Multivariate normative comparisons indicated that 27% of the HIV+ group evidenced global neurocognitive impairment.
Conclusions:Overall, results support the validity of a neurocognitive battery adapted for use in Botswana, a non-Western, resource-limited setting. Results indicated that the adapted battery applied to children and adolescents with limited computer familiarity had a similar factor structure as in Western settings, indicating that the PennCNB appeared to assess the hypothesized neurocognitive domains. Hypothesized associations with age and sex supported the battery’s construct validity. Moreover, the battery appears to be sensitive to cognitive impairments associated with perinatally-acquired HIV and in utero HIV-related exposures, as it discriminated between the HUU, HIV+, and HEU groups. Differences were found in specific domains and in detection of overall impairment, including approximately one quarter of children and adolescents living with HIV in this cohort evidencing global neurocognitive impairment. Together, these results provide evidence that the PennCNB could serve as a useful tool for the assessment of neurocognitive functioning in school-aged children and adolescents from Botswana and, potentially, other resource-limited settings.

Harvey S. Levin obtained his Bachelor’s degree from City College of New York, in New York city, Ph.D. in Clinical Psychology from the University of Iowa, in Iowa City, completed his internships in Clinical Neuropsychology and Pediatric Psychology at the University of Iowa Hospitals in Iowa City and Clinical Psychology, Psychiatry and Pediatrics at the Illinois Masonic Medical Center in Chicago, and his fellowship in Neuropsychology at University of Iowa Hospitals in Iowa City.
Dr. Levin started his career in 1972 as Instructor with the Department of Psychology at the University of Iowa and transitioned to The University of Texas Medical Branch (UTMB) in Galveston, Texas, in 1974, where he began an internationally renowned career in clinical work, teaching, and, most of all, pioneering research on traumatic brain injury (TBI). He ultimately became the Chela and Jimmy Storm Distinguished Professor in Surgical Research, Division of Neurosurgery, Department of Surgery in 1987. After leaving Texas for two years to take a position with the University of Maryland Medical System and Shock Trauma Institute in Baltimore, he moved back to Houston Texas in 1995 and established the Cognitive Neuroscience Laboratory (CNL) within the Department of Physical Medicine & Rehabilitation at Baylor College of Medicine, which was supported by federal grants, including funding from the National Institutes of Health, Department of Defense, Department of Veterans Affairs, and Centers for Disease Control and Prevention, and numerous private foundations. The CNL integrated rehabilitation and neuroplasticity research with multimodality brain imaging, clinical and neuropsychological assessment, and fluid biomarkers. Dr. Levin was Professor with the Departments of Physical Medicine and Rehabilitation where he served as Director of Research (1995-2014), Pediatrics, and Neurosurgery at Baylor College of Medicine. He was also a Research Scientist and the Director of the Center of Excellence for Traumatic Brain Injury at the Michael E. DeBakey Veterans Affairs Medical Center (2008-2013), and Adjunct Professor with the Department of Psychology at Rice University in Houston, Texas.
Dr. Levin’s research focused on investigating both acute and long-term outcomes of mild to severe TBI in civilian and military populations, including cognitive and behavioral sequelae in relation to neuropathology using advanced brain imaging modalities. He began prospective, longitudinal studies of adults and children who had sustained TBI associated with closed head trauma upon joining UTMB and developed, in collaboration with Drs O’Donnell and Grossman, the Galveston Orientation and Amnesia Test (GOAT). The GOAT was the first measure to assess post-traumatic amnesia and orientation following moderate to severe TBI, is still most widely used by the clinicians and researchers, and it has been translated to 16 languages. The original publication, “Levin HS, O’Donnell VM, Grossman RG. The Galveston Orientation and Amnesia Test. A practical scale to assess cognition after head injury. J Nerv Ment Dis. 1979 Nov;167(11):675-84. doi: 10.1097/00005053-197911000-00004. PMID: 501342”, has over 1200 citations. This work continued with participation in the NINDS Traumatic Coma Data Bank and the organization of outcome assessments for NINDS-funded clinical trials of hypothermia to treat severe TBI. To monitor the quality of outcome data across performing sites, Dr. Levin and colleagues developed a code for the reliability of data collected and implemented the role of an outcome monitor who evaluated adherence to protocol across sites. Following establishment of the CNL, he pursued investigation of TBI outcomes across the lifespan using multimodality brain imaging and biomarkers, errorless learning, translational studies in collaboration with neuroscientists using animal models, and clinical trials of methylphenidate, progesterone, CDP-choline. Dr. Levin spent over 30 years researching neurobehavioral outcomes of head injury in children, starting with a small pilot study funded by the Shriners Hospital in 1991 and continuing with several cycles of a multicenter R01 grant funded by the National Institute of Health. In later years, he used his expertise as a member of several large consortiums, including the Long-term Impact of Military-Relevant Brain Injury Consortium \ Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) funded by the VA and DoD and the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) funded by the NINDS.
During his career, Dr. Levin authored and coauthored more than 400 articles in scientific journals and over 100 books, with one of them, “Levin, H. S., Benton, A. L., & Grossman, R. G. (1982). Neurobehavioral consequences of closed head injury. Oxford University Press, USA”, having over 1100 citation, as well as book chapters that advanced knowledge of TBI, epilepsy, neurodegenerative diseases, and other illnesses that affect brain functioning. He was also very active as a reviewer on federal grant panels and as an editor and reviewer for the Journal of Neurotrauma, Journal of Clinical and Experimental Neuropsychology, Archives of Physical Medicine & Rehabilitation, Neuropsychology, Journal of the International Neuropsychological Society, Lancet, JAMA, Pediatrics, and other top-cited journals. He served as president of the International Neuropsychological Society in 1989-1990. Dr. Levin was a recipient of numerous prestigious awards, including the Javits Neuroscience Investigator Award, the Jennett-Plum Award for Research on Traumatic Brain Injury, the Distinguished Career Award by the International Neuropsychological Society, the American Congress of Rehabilitation Gold Key Award, the Distinguished Lifetime Contribution to Neuropsychology Award from the National Academy of Neuropsychology, as well as awards from other head injury and psychological organizations, including the International Brain Injury Association, the National Head Injury Foundation, the North American Brain Injury Society, Texas Psychological Association, and the Defense and Veterans Brain Injury Center. In addition to his stellar scientific accomplishments, Dr. Levin trained, mentored, and provided supervision to interns, fellows, postdocs, residents, medical and psychology students. He was the Director of an NCMRR/NIH T32 Postdoctoral Research Program, and training supervisor in neuropsychology for Baylor College of Medicine and for the Memorial Hermann TIRR Neuropsychology Postdoctoral Fellowship Programs. A passionate educator, he taught classes at Baylor College of Medicine, the University of Houston, and the National and Kapodistrian University of Athens Medical School in Greece and served as an evaluator for the American Board of Clinical Neuropsychology/American Board of Professional Psychology. He was often invited as a lecturer at numerous scientific organizations.
The main objective of this symposium is to provide an overview of the current state of research in TBI while highlighting Dr. Levin’s contributions to this field. The symposium will start with a brief overview of Dr. Levin’s career (Dr. Randall S. Scheibel), followed by presentations focused on the assessment of adult TBI, including posttraumatic amnesia (Dr. Felicia C. Goldstein), the current state of pediatric TBI (Dr. L. Ewing-Cobbs), and novel imaging in TBI (Dr. Erin D. Bigler). There will be a brief discussion session at the end lead by Dr. Elisabeth A. Wilde.

Objectives:
Data from neurocognitive assessments may not be accurate in the context of factors impacting validity, such as disengagement, unmotivated responding, or intentional underperformance. Performance validity tests (PVTs) were developed to address these phenomena and assess underperformance on neurocognitive tests. However, PVTs can be burdensome, rely on cutoff scores that reduce information, do not examine potential variations in task engagement across a battery, and are typically not well-suited to acquisition of large cognitive datasets. Here we describe the development of novel performance validity measures that could address some of these limitations by leveraging psychometric concepts using data embedded within the Penn Computerized Neurocognitive Battery (PennCNB).
Methods:We first developed these validity measures using simulations of invalid response patterns with parameters drawn from real data. Next, we examined their application in two large, independent samples: 1) children and adolescents from the Philadelphia Neurodevelopmental Cohort (n = 9498); and 2) adult servicemembers from the Marine Resiliency Study-II (n = 1444).
Results:Our performance validity metrics detected patterns of invalid responding in simulated data, even at subtle levels. Furthermore, a combination of these metrics significantly predicted previously established validity rules for these tests in both developmental and adult datasets. Moreover, most clinical diagnostic groups did not show reduced validity estimates.
Conclusions:These results provide proof-of-concept evidence for multivariate, data-driven performance validity metrics. These metrics offer a novel method for determining the performance validity for individual neurocognitive tests that is scalable, applicable across different tests, less burdensome, and dimensional. However, more research is needed into their application.

Electronic platforms provide an opportunity to improve the informed consent (IC) process by permitting elements shown to increase research participant understanding and satisfaction, such as graphics, self-pacing, meaningful engagement, and access to additional information on demand. However, including these elements can pose operational and regulatory challenges for study teams and institutional review boards (IRBs) responsible for the ethical conduct and oversight of research. We examined the experience of two study teams at Alzheimer’s Disease Research Centers who chose to move from a paper-based IC process to an electronic informed consent (eIC) process to highlight some of these complexities and explore how IRBs and study teams can navigate them. Here, we identify the key regulations that should be considered when developing and using an eIC process as well as some of the operational considerations eIC presents related to IRB review and how they can be addressed.

Background
Evidence suggests a link between smaller hippocampal volume (HV) and post-traumatic stress disorder (PTSD). However, there has been little prospective research testing this question directly and it remains unclear whether smaller HV confers risk or is a consequence of traumatization and PTSD.
MethodsU.S. soldiers (N = 107) completed a battery of clinical assessments, including structural magnetic resonance imaging pre-deployment. Once deployed they completed monthly assessments of traumatic-stressors and symptoms. We hypothesized that smaller HV would potentiate the effects of traumatic stressors on PTSD symptoms in theater. Analyses evaluated whether total HV, lateral (right v. left) HV, or HV asymmetry (right – left) moderated the effects of stressor-exposure during deployment on PTSD symptoms.
ResultsFindings revealed no interaction between total HV and average monthly traumatic-stressors on PTSD symptoms b = −0.028, p = 0.681 [95% confidence interval (CI) −0.167 to 0.100]. However, in the context of greater exposure to average monthly traumatic stressors, greater right HV was associated with fewer PTSD symptoms b = −0.467, p = 0.023 (95% CI −0.786 to −0.013), whereas greater left HV was unexpectedly associated with greater PTSD symptoms b = 0.435, p = 0.024 (95% CI 0.028–0.715).
ConclusionsOur findings highlight the importance of considering the complex role of HV, in particular HV asymmetry, in predicting the emergence of PTSD symptoms in response to war-zone trauma.

Specialised rehabilitation units offer inpatient multi-disciplinary rehabilitation for individuals with severe and enduring mental illness. A cornerstone of therapy is the work in the community through further education and community organisations. However, coronavirus restrictions have meant that such external supports are no longer available for the duration of the crisis. This has led to opportunities for developing new ways of offering rehabilitation within hospital environments. This article describes some of the new initiatives developed. The benefits of the lockdown for service users are also discussed. Many found the cessation of visits from family members with whom they had an ambivalent relationship helpful. The lockdown improved relationships between patients on the unit and encouraged a greater feeling of community. The lockdown has also emphasised the importance of team self-awareness and an awareness of the nature of the treatments offered.

We describe the design and deployment of GREENBURST, a commensal Fast Radio Burst (FRB) search system at the Green Bank Telescope. GREENBURST uses the dedicated L-band receiver tap to search over the 960–1 920 MHz frequency range for pulses with dispersion measures out to $10^4\ \rm{pc\,cm}^{-3}$ . Due to its unique design, GREENBURST is capable of conducting searches for FRBs when the L-band receiver is not being used for scheduled observing. This makes it a sensitive single pixel detector capable of reaching deeper in the radio sky. While single pulses from Galactic pulsars and rotating radio transients will be detectable in our observations, and will form part of the database we archive, the primary goal is to detect and study FRBs. Based on recent determinations of the all-sky rate, we predict that the system will detect approximately one FRB for every 2–3 months of continuous operation. The high sensitivity of GREENBURST means that it will also be able to probe the slope of the FRB fluence distribution, which is currently uncertain in this observing band.

Good education requires student experiences that deliver lessons about practice as well as theory and that encourage students to work for the public good—especially in the operation of democratic institutions (Dewey 1923; Dewy 1938). We report on an evaluation of the pedagogical value of a research project involving 23 colleges and universities across the country. Faculty trained and supervised students who observed polling places in the 2016 General Election. Our findings indicate that this was a valuable learning experience in both the short and long terms. Students found their experiences to be valuable and reported learning generally and specifically related to course material. Postelection, they also felt more knowledgeable about election science topics, voting behavior, and research methods. Students reported interest in participating in similar research in the future, would recommend other students to do so, and expressed interest in more learning and research about the topics central to their experience. Our results suggest that participants appreciated the importance of elections and their study. Collectively, the participating students are engaged and efficacious—essential qualities of citizens in a democracy.

Background
Traumatic stressors during childhood and adolescence are associated with psychopathology, mostly studied in the context of post-traumatic stress disorder (PTSD) and depression. We investigated broader associations of traumatic stress exposure with psychopathology and cognition in a youth community sample.
MethodsThe Philadelphia Neurodevelopmental Cohort (N = 9498) is an investigation of clinical and neurobehavioral phenotypes in a diverse (56% Caucasian, 33% African American, 11% other) US youth community population (aged 8–21). Participants were ascertained through children's hospital pediatric (not psychiatric) healthcare network in 2009–2011. Structured psychiatric evaluation included screening for lifetime exposure to traumatic stressors, and a neurocognitive battery was administered.
ResultsExposure rate to traumatic stressful events was high (none, N = 5204; one, N = 2182; two, N = 1092; three or more, N = 830). Higher stress load was associated with increased psychopathology across all clinical domains evaluated: mood/anxiety (standardized β = .378); psychosis spectrum (β = .360); externalizing behaviors (β = .311); and fear (β = .256) (controlling for covariates, all p < 0.001). Associations remained significant controlling for lifetime PTSD and depression. Exposure to high-stress load was robustly associated with suicidal ideation and cannabis use (odds ratio compared with non-exposed 5.3 and 3.2, respectively, both p < 0.001). Among youths who experienced traumatic stress (N = 4104), history of assaultive trauma was associated with greater psychopathology and, in males, vulnerability to psychosis and externalizing symptoms. Stress load was negatively associated with performance on executive functioning, complex reasoning, and social cognition.
ConclusionsTraumatic stress exposure in community non-psychiatric help-seeking youth is substantial, and is associated with more severe psychopathology and neurocognitive deficits across domains, beyond PTSD and depression.

Objectives: Neuropsychological studies of posttraumatic stress disorder (PTSD) have revealed deficits in attention/working memory, processing speed, executive functioning, and retrospective memory. However, little is known about prospective memory (PM) in PTSD, a clinically relevant aspect of episodic memory that supports the encoding and retrieval of intentions for future actions. Methods: Here we examined PM performance in 40 veterans with PTSD compared to 38 trauma comparison (TC) veterans who were exposed to combat but did not develop PTSD. All participants were administered the Memory for Intentions Test (MIST; Raskin, Buckheit, & Sherrod, 2010), a standardized and validated measure of PM, alongside a comprehensive neurocognitive battery, structured diagnostic interviews for psychiatric conditions, and behavioral questionnaires. Results: Veterans with PTSD performed moderately lower than TC on time-based PM, with errors primarily characterized as PM failure errors (i.e., omissions). However, groups did not differ in event-based PM, ongoing task performance, or post-test recognition of PM intentions for each trial. Lower time-based PM performance was specifically related to hyperarousal symptoms of PTSD. Time-based-performance was also associated with neuropsychological measures of retrospective memory and executive functions in the PTSD group. Nevertheless, PTSD was significantly associated with poorer PM above and beyond age and performance in retrospective memory and executive functions. Discussion: Results provide initial evidence of PM dysfunction in PTSD, especially in strategic monitoring during time-based PM tasks. Findings have potential implications for everyday functioning and health behaviors in persons with PTSD, and deserve replication and future study. (JINS, 2016, 22, 724–734)

A sequence of unusual vertical tubes, arranged in multiple groups, and each tube several meters high occurs in the Middlesboro Member of the Lee Formation (Lower Pennsylvanian). These structures are controversial with various interpretations suggesting either plant or animal origin. Observations supporting a plant origin include: 1) numerous C- and D-shaped, and multichambered tube cross sections are similar to fern and seed fern structures, 2) numerous membrane relicts loosely enclosing the tubes are similar to fern and seed fern tissues, 3) microscopic bundles are observed in cross-sectional thin sections, 4) presence of carbonaceous material and reported fecal pellets over a vertical distance in excess of 5 m are consistent with deteriorating plant material, not escape structures, 5) tubes are composed of casts and molds, but lack spreite or other features typical of escape structures, 6) tubes occur in clusters about one meter in diameter and are associated with coaly material at their base, which suggests that the clusters represent trees, 7) other trace fossils are absent in the enclosing sandstone, 8) tubes branch upward, which is a common structure in plants but unlikely in escape structures, 9) a coalified root structure was found at the base of the sandstone, and 10) all the tubes extend from the bottom of the sandstone to the top. The probability of burrowing animals escaping through as much as 8 m of sand with 100 percent survivorship is low.
The structures may represent a stand of pteridosperms with each “tree” approximately 1–1.5 m in diameter. The individual pipe-organ structures represent aerial stems, shoots, and adventitious roots; each cluster of pipe-organ structures represents a single tree.
Based upon sedimentologic features such as presence of 1) channel form, 2) scoured base, and 3) fining-upward sequence, we interpret the sandstone containing the pipe-organ structures to have been deposited in a sandy fluvial or tidal channel. The unidirectional cross-bed dips, poor sorting, occurrence only of very restrictive fauna and terrestrial flora, position of the sandstone above a possible floodplain facies, and lack of characteristic tidal structures suggest that the sandstone is more probably a sandy fluvial channel that may have minor tidal influence.

Objectives: Numerous studies have shown that individuals with posttraumatic stress disorder (PTSD) display reduced performances on neuropsychological tests, although most prior research has not adequately accounted for comorbidities or performance validity concerns that are common in this population and could partially account for the observed neurocognitive findings. Moreover, few studies have examined the functional implications of neuropsychological results in PTSD. Methods: We examined neuropsychological functioning in 44 veterans with PTSD and 40 veteran trauma comparison (TC) participants with combat exposure and no PTSD. Results: After excluding four veterans with PTSD for performance validity concerns, multivariate analyses of variance by neurocognitive domain revealed significantly worse performance by the PTSD group in the domains of speed of information processing (p=.035) and executive functions (p=.017), but no group differences in attention/working memory, verbal/language functioning, visuoconstruction, or episodic memory. Group differences by PTSD status were still present after covarying for depression, a history of head injuries, and substance use disorders. Executive functioning performance was associated with poorer self-reported occupational functioning and physical health-related quality of life, while speed of information processing performance was associated with poorer physical health-related quality of life. Discussion: These results are generally consistent with a fronto-limbic conceptualization of PTSD-associated neuropsychological dysfunction and show that cognitive functioning may be associated with critical functional outcomes. Taken together, results suggest that consideration of neurocognitive functioning may enhance the clinical management of individuals with PTSD. (JINS, 2016, 22, 399–411)

Ultrasonic nondestructive evaluation methods are routinely used to detect and size fatigue cracks near fastener holes in aircraft structures as a part of scheduled maintenance. In contrast, statistical crack propagation models provide an estimate of the expected fatigue life assuming a known crack size and future fatigue loadings. Here an integrated approach for in situ diagnosis and prognosis of fastener hole fatigue cracks is proposed and implemented that incorporates both ultrasonic monitoring and crack growth laws. The sensing method is an ultrasonic angle beam technique, and cracks are automatically detected from the ultrasonic response. An extended Kalman filter is applied to combine ultrasonically estimated crack sizes with a crack growth law, effectively using the time history of the ultrasonic results rather than only the most recent measurement. A natural extension of this method is fatigue life prognosis. Results from fatigue tests on 7075-T651 aluminium coupons show improved crack size estimates as compared to those obtained from ultrasonic measurements alone, and also demonstrate the capability of predicting the remaining life. This approach for fatigue crack detection, sizing and prognosis is an example of a general strategy for in situ monitoring of structural damage whereby improved results are achieved from the integration of noisy measurements with imperfect crack growth models.

BACKGROUND
Influenza A (H1N1) pdm09 became the predominant circulating strain in the United States during the 2013–2014 influenza season. Little is known about the epidemiology of severe influenza during this season.
METHODSA retrospective cohort study of severely ill patients with influenza infection in intensive care units in 33 US hospitals from September 1, 2013, through April 1, 2014, was conducted to determine risk factors for mortality present on intensive care unit admission and to describe patient characteristics, spectrum of disease, management, and outcomes.
RESULTSA total of 444 adults and 63 children were admitted to an intensive care unit in a study hospital; 93 adults (20.9%) and 4 children (6.3%) died. By logistic regression analysis, the following factors were significantly associated with mortality among adult patients: older age (>65 years, odds ratio, 3.1 [95% CI, 1.4–6.9], P=.006 and 50–64 years, 2.5 [1.3–4.9], P=.007; reference age 18–49 years), male sex (1.9 [1.1–3.3], P=.031), history of malignant tumor with chemotherapy administered within the prior 6 months (12.1 [3.9–37.0], P<.001), and a higher Sequential Organ Failure Assessment score (for each increase by 1 in score, 1.3 [1.2–1.4], P<.001).
CONCLUSIONRisk factors for death among US patients with severe influenza during the 2013–2014 season, when influenza A (H1N1) pdm09 was the predominant circulating strain type, shifted in the first postpandemic season in which it predominated toward those of a more typical epidemic influenza season.

Although beta-amyloid, anxiety and depression have been linked cross-sectionally to reduced memory function in healthy older adults without dementia, prospective data evaluating these associations are lacking. Using data from an observational cohort study of 178 healthy older adults without dementia followed for 3 years, we found that anxiety symptoms significantly moderated the relationship between beta-amyloid level and decline in verbal (Cohen's d = 0.65) and episodic (Cohen's d = 0.38) memory. Anxiety symptoms were additionally linked to greater decline in executive function, irrespective of beta-amyloid and other risk factors. These findings suggest that interventions to mitigate anxiety symptoms may help delay memory decline in otherwise healthy older adults with elevated beta-amyloid.

Contemporary research on prehispanic Maya landscapes has focused on caves as core features of the cultural geography. Investigations within a number of large caves have suggested that they served as the loci for important rituals, legitimized inhabitants’ claims to their territory, and helped establish the authority of a site’s ruling elite. The ubiquity and centrality of caves in the Maya worldview raises questions about what happened in regions where large caves did not naturally form. Recent investigations at the site of Maax Na in northern Belize suggest that small caves, despite their diminutive size, still functioned to establish legitimacy and uphold power. The results serve to demonstrate the pervasive power of key ideological concepts in shaping the cultural landscape and indicate the need to take these into account in documenting landmarks at Maya sites, as even the less imposing ones may have been important to their inhabitants.

As part of a programme to test the sterile insect technique against Glossina morsitans morsitans Westw. in Tanzania, two aerial applications of endosulfan were applied to a 195-km2 test area. The applications were made with a 28-day interval to provide an initial reduction in the target species prior to the release of sterile males. A Cessna 310 aircraft equipped with a rotary atomiser and operating at night was used to apply the insecticide at a dosage of about 20 g/ha. Flyround surveys within 48 h following the spraying operations indicated that a 100% reduction of G. m. morsitans adults was achieved in both applications, while G. pallidipes Aust. was reduced by 91 5% in the first and 100% in the second.

The presence of angiotensin I-converting enzyme-like activity (ACELA) was investigated in whole body homogenates of Branchiostoma lanceolatum using a highly sensitive fluorimetric assay. The measured enzyme activity was inhibited by the two angiotensin converting enzyme inhibitors, captopril and enalapril, suggesting a biochemical pathway that could generate the angiotensins observed in the central nervous system of amphioxus.
