description: Objective: To examine prospective, bidirectional associations between homelessness and substance use frequency among young adults receiving substance use treatment in the United States. We also investigated potential differences across demographic subgroups. Methods: Young adults (N = 3717, Mage = 20.1, 28% female, 7.3% sexual/gender minority, and 37% non-Hispanic White) receiving substance use treatment in the U.S. completed assessments at intake, 3 months, 6 months, and 12 months post-intake. Latent growth curve models with structured residuals (LGC-SR) were used to examine cross-lagged associations between homeless days and frequency of substance use and associated problems. Models were stratified by sex, race/ethnicity, and sexual and/or gender minority status. Results: Overall, days spent homeless (μslope= −0.19, p = 0.046) and substance use frequency (μslope1= −6.19, p < 0.001) significantly decreased during treatment, with no significant cross-lagged associations between homeless days and substance use frequency. However, results differed by race and ethnicity. For non-Hispanic White young adults, greater substance use at treatment entry was associated with steeper declines in homeless days between-persons (ϕstandardized = −0.14, p = 0.04). For African Americans, homeless days at treatment entry were associated with greater increases in substance use between-persons (ϕstandardized = 0.29, p = 0.04). No significant differences were found by sex or sexual/gender minority status. Conclusions: Despite overall declines in homelessness and substance use during treatment, these outcomes may unfold differently for non-Hispanic White and African American young adults. More support may be needed for African American young adults reporting homelessness at treatment entry.

Share, but unequally: A plausible mechanism for emergence and maintenance of intratumor heterogeneity - Supplementary Information

Publisher: name: The Royal Society

description: Intratumour heterogeneity (ITH), referring to coexistence of different cell subpopulations in a single tumour, has been a major puzzle in cancer research for almost half a century. The lack of understanding of the underlying mechanism of ITH hinders progress in developing effective therapies for cancers. Based on the findings in a recent quantitative experiment on pancreatic cancer, we developed a general evolutionary model for one type of cancer, accounting for interactions between different cell populations through paracrine or juxtacrine factors. We show that the emergence of a stable heterogeneous state in a tumour requires an unequal allocation of paracrine growth factors (public goods) between cells that produce them and those that merely consume them. Our model provides a quantitative explanation of recent in vitro experimental studies in pancreatic cancer in which insulin growth factor (IGF-II) plays the role of public goods. The calculated phase diagrams as a function of exogenous resources and fraction of growth factor producing cells show ITH persists only in a narrow range of concentration of exogenous IGF-II. Remarkably, maintenance of ITH requires cooperation among tumour cell subpopulations in harsh conditions, specified by lack of exogenous IGF-II, whereas surplus exogenous IGF-II elicits competition. Our theory also quantitatively accounts for measured in vivo tumour growth in glioblastoma multiforme (GBM). The predictions for GBM tumour growth as a function of the fraction of tumour cells are amenable to experimental tests. The mechanism for ITH also provides hints for devising efficacious therapies.
Bell's Theorem and the Causal Arrow of Time

description: Einstein held that the formalism of Quantum Mechanics (QM) entails "spooky actions at a distance". Indeed, in the 60's Bell showed that the predictions of QM disagree with the results of any locally causal description. Accepting non-local descriptions while retaining causality leads to a clash with the theory of relativity. Furthermore, the causal arrow of time by definition contradicts time-reversal symmetry. For these reasons, some authors (Feynman and Wheeler, Costa de Beauregard, Cramer, Price) have advocated abandoning microscopic causality. In the present article, a simplistic but concrete example of following this line of thought is presented, in the form of a retro-causal toy-model which is stochastic and which provides an appealing description of the specific quantum correlations discussed by Bell. One concludes that Einstein's "spooky actions" may occur "in the past" rather than "at a distance", resolving the tension between QM and relativity, and opening unexplored possibilities for future reformulations of QM.

Revealing Thermal Comptonization of accretion-disk photons in IC4329A with AstroSat

description: We present five simultaneous UV/X-ray observations of IC4329A by AstroSat, performed over {a five-month} period. We utilize the excellent spatial resolution of the Ultra-Violet Imaging Telescope (UVIT) onboard AstroSat to reliably separate the intrinsic AGN flux from the host galaxy emission and to correct for the Galactic and internal reddening, as well as the contribution from the narrow and broad-line regions. We detect large-amplitude UV variability, which is unusual for a large black hole mass AGN, like IC4329A, over such a small period. In fact, the fractional variability amplitude is larger in the UV band than in the X-ray band. This demonstrates that the observed UV variability is intrinsic to the disk, and is not due to X-ray illumination. The joint X-ray spectral analyses of five SXT and LAXPC spectral data reveal a soft-X-ray excess component, a narrow iron-line (with no indication of a significant Compton hump), and a steepening power-law ($ΔΓ\sim 0.21$) with increasing X-ray flux. The soft excess component could arise due to thermal Comptonization of the inner disk photons in a warm corona with $kT_e\sim 0.26$ keV. The UV emission we detect acts as the primary seed photons for the hot corona, which produces the broadband X-ray continuum. The X-ray spectral variability is well described by the cooling of this corona from $kT_e\sim42$ keV to $\sim 32$ keV with increasing UV flux, while the optical depth remains constant at $τ\sim 2.3$.

description: We describe a numerical method to compute Casimir forces in arbitrary geometries, for arbitrary dielectric and metallic materials, with arbitrary accuracy (given sufficient computational resources). Our approach, based on well-established integration of the mean stress tensor evaluated via the fluctuation-dissipation theorem, is designed to directly exploit fast methods developed for classical computational electromagnetism, since it only involves repeated evaluation of the Green's function for imaginary frequencies (equivalently, real frequencies in imaginary time). We develop the approach by systematically examining various formulations of Casimir forces from the previous decades and evaluating them according to their suitability for numerical computation. We illustrate our approach with a simple finite-difference frequency-domain implementation, test it for known geometries such as a cylinder and a plate, and apply it to new geometries. In particular, we show that a piston-like geometry of two squares sliding between metal walls, in both two and three dimensions with both perfect and realistic metallic materials, exhibits a surprising non-monotonic ``lateral'' force from the walls.

A Look at the Abandoned Contributions to Cosmology of Dirac, Sciama and Dicke

description: The separate contributions to cosmology of the above researchers are revisited and a cosmology encompassing their basic ideas is proposed. We study Dirac's article on the large number hypothesis (1938), Sciama's proposal of realizing Mach's principle (1953), and Dicke's considerations (1957) on a flat-space representation of general relativity with a variable speed of light (VSL). Dicke's tentative theory can be formulated in a way which is compatible with Sciama's hypothesis on the gravitational constant G. Additionally, such a cosmological model is shown to satisfy Dirac's second `large number' hypothesis on the total number of particles in the universe being proportional to the square of the epoch. In the same context, Dirac's first hypothesis on an epoch-dependent G-contrary to his prediction- does not necessarily produce a visible time dependence of G. While Dicke's proposalreproduces the classical tests of GR in first approximation, the cosmological redshift is described by a shortening of measuring rods rather than an expansion of space. Since the temporal evolution of the horizon R is governed by \dot R(t) =c(t), the flatness and horizon problems do not arise in the common form.

description: While growing evidence has identified mental and physical health-related cannabis use motives as significant mechanisms between childhood trauma and problematic cannabis use (PCU) for emerging adults (EA), there is a need to understand the longitudinal stability of these pathways and how they impact PCU as cannabis users age into later adulthood. The current study extends an analysis examining the impact of childhood trauma (e.g., emotional abuse, sexual abuse) on multiple indicators of PCU through a range of cannabis use motives. 339 medical cannabis patient and non-patient EA users from the Los Angeles area were sampled at baseline (mean age = 21.23; SD = 2.48). The present analysis used four waves of follow-up data collected from 2016 to 2018 (W3, W4) and 2019-2020 (W5, W6). Use of cannabis to cope with nausea, sleep, pain, and emotional distress mediated the relationships between some types of childhood abuse and PCU at W4, though most associations attenuated by later adulthood (W6). Specifically, greater emotional distress and nausea motives were associated with greater PCU in models of emotional abuse and neglect and sexual abuse, with emotional distress continuing to mediate at W6. Conversely, sleep and pain motives were associated with lower PCU in models for emotional neglect. Mental and physical health-related motives reflect potential intervenable factors that predict PCU in emerging adulthood among EA cannabis users with histories of childhood trauma. Results highlight the importance of and value for assessing a wide range of motives and PCU outcomes to target and address areas for intervention.
Teacher efficacy : its relationship to school level organizational conditions and teacher demographic characteristics
Creators: name: Cavers, Lloyd
Publisher: name: University of British Columbia
Year: 2010

description: This empirical study explored the relationship between teacher efficacy and each of school level organizational conditions and teacher demographic characteristics in order to provide information which could be used in school improvement planning. Teacher efficacy, the extent to which teachers believe they have the capacity to affect student performance, has two components as defined in this study: teaching efficacy, and personal teaching efficacy. Teaching efficacy, considered to be a general measure of teacher efficacy, describes the teacher's belief in the ability of teachers, as a group, to influence learning. Personal teaching efficacy, considered to be the more specific and important measure of the two, describes the belief that the individual teacher has the skills and abilities to bring about student learning. The teacher's sense of personal teaching efficacy is believed to have the most potential for affecting the teacher's motivation and future behaviour. A teacher's sense of efficacy is believed to be affected by several variables including school level organizational conditions and teacher demographic characteristics. Nine school level organizational conditions and five teacher demographic characteristics were selected for study from the literature because they had been positively related to good schools. A volunteer sample of 339 school-based teachers in one Alberta school district were surveyed and the principal of each of 15 schools was interviewed. Quantitative analyses were used with the teacher as the unit of analysis; these findings were verified and amplified using a qualitative analysis with the school as the unit of analysis. The main conclusions were: (1) teacher sex and teaching grade level were significantly related to teacher efficacy, while teacher age and experience were not; and (2) teachers' perceptions of student behaviour and horizontal communication were significantly related to teacher efficacy. The study suggests seven implications for school administrators and others interested in enhancing teachers' sense of efficacy. These include: (1) providing opportunities for teachers to discuss instruction-related topics; and (2) implementing a school discipline policy aimed at improving student behaviour. Ten implications for further research include the consideration of a secondary school focus and also the use of research methods with the potential to establish a causal relationship between teacher efficacy and school level organizational conditions.

description: This work is part of the NUGA survey of CO emission in nearby active galaxies. We present observations of NGC4569, a member of the Virgo Cluster. We analyse the molecular gas distribution and kinematics in the central region and we investigate a possible link to the strong starburst present at the nucleus. 70% of the 1.1x10^9 Msolar of molecular gas detected in the inner 20" is found to be concentrated within the inner 800 pc and is distributed along the large scale stellar bar seen in near-infrared observations. A hole in the CO distribution coincides with the nucleus where most of the Halpha emission and blue light are emitted. The kinematics are modelled in three different ways, ranging from the purely geometrical to the most physical. This approach allows us to constrain progressively the physical properties of the galaxy and eventually to emerge with a reasonable fit to an analytical model of orbits in a barred potential. Fitting an axisymmetric model shows that the non-circular motions must be comparable in amplitude to the circular motions (120 km/s). Fitting a model based on elliptical orbits allows us to identify with confidence the single inner Lindblad resonance (ILR) of the large scale bar. Finally, a model based on analytical solutions for the gas particle orbits in a weakly barred potential constrained by the ILR radius reproduces the observations well. The mass inflow rate is then estimated and discussed based on the best fit model solution. The gravitational torques implied by this model are able to efficiently funnel the gas inside the ILR down to 300 pc, although another mechanism must take over to fuel the nuclear starburst inside 100 pc.

We find a dramatic difference in the magnetization between the two directions. It is biggest at low measurement fields $H$ or high temperatures. We show that the difference at high temperatures must emerge from Ising-like exchange anisotropy. This allows us to explain muon spin rotation data at $T\to 0$ in terms of an exotic ferromagnetic ground state.

description: Physical spin configurations corresponding to topological excitations, expected to be present in the XY limit of a quantum spin 1/2 Heisenberg anti-ferromagnet, are probed on a two dimensional square lattice . Quantum vortices (anti-vortices) are constructed in terms of coherent staggered spin field components, as limiting case of meronic (anti-meronic) configurations . The crucial role of the associated Wess-Zumino-like (WZ-like) term is highlighted in our procedure . The time evolution equation of coherent spin fields used in this analysis is obtained by applying variational principle on the quantum Euclidean action corresponding to the Heisenberg anti-ferromagnet on lattice . It is shown that the WZ-like term can distinguish between vortices and anti-vortices only in a charge sector with odd topological charges. Our formalism is distinctly different from the conventional approach for the construction of quantum vortices (anti-vortices) .

description: Youth use of electronic cigarettes (“e-cigarettes”) is an ongoing concern. Vaping is usually assumed to be of nicotine, but survey responses may also include vaping of non-nicotine substances (particularly cannabis), which can impose different risks. The current study quantifies the proportions of nicotine-specific and cannabis-specific vaping among adolescents. Data from the Monitoring the Future (MTF) 2021 survey were analyzed with respect to the substance vaped: nicotine, cannabis, or flavoring only. Past-30-day (P30D) nicotine-specific vaping (exclusively, or also having vaped other substances) and cannabis-specific vaping were calculated. Results were also broken down by grade level, cigarette smoking history (current, former, or never), and frequency of e-cigarette use (<20 vs. 20+ days in P30D). Among 4706 P30D e-cigarette users, 84.2% vaped nicotine; the remaining 15.8% reported not vaping any nicotine in P30D. Cannabis vaping was reported by 48.4% of P30D vapers. Vaping both nicotine and cannabis in P30D was more common in current and former smokers than in never-smokers, and in frequent vapers (of any substance). Conversely, never-smokers were more commonly vaping cannabis but not nicotine, compared to current and former smokers. Supplementary NYTS 2022 analyses were consistent with these findings. A notable proportion of self-reported P30D vapers reported not vaping nicotine; nearly half vaped cannabis. Capturing the variety of substances used in vaping devices is imperative for accurate public health surveillance of both nicotine and cannabis vaping among US adolescents, considering their different respective harms and regulatory frameworks.

description: This study of adsorption of normal alkanols at the oil/water interface with x-ray reflectivity and tensiometry demonstrates that the liquid to gas monolayer phase transition at the hexane/water interface is thermodynamically favorable only for long-chain alkanols. As the alkanol chain length is decreased, the change in excess interfacial entropy per area decreases to zero. Systems with small values of excess interfacial entropy form multi-molecular layers at the interface instead of the monolayer formed by systems with much larger excess interfacial entropy. Substitution of n-hexane by n-hexadecane significantly alters the interfacial structure for a given alkanol surfactant, but this substitution does not change fundamentally the phase transition behavior of the monolayers. These data show that the critical alkanol carbon number, at which the change in excess interfacial entropy per area decreases to zero, is approximately six carbons larger than the number of carbons in the alkane solvent molecules.

description: The direct imaging of rocky exoplanets is one of the major science goals for upcoming large telescopes. The contrast requirement for imaging such planets is challenging. However, the mid-IR (InfraRed) regime provides the optimum contrast to directly detect the thermal signatures of exoplanets in our solar neighbourhood. We aim to exploit novel fast chopping techniques newly developed for astronomy with the aid of adaptive optics to look for thermal signatures of exoplanets around bright stars in the solar neighbourhood. We use the upgraded VISIR (Very Large Telescope Imager and Spectrometer for the mid-InfraRed) instrument with high contrast imaging (HCI) capability optimized for observations at 10~$μ$m to look for exoplanets around five nearby ($d$ < 4 pc) stars. The instrument provides an improved signal-to-noise (S/N) by a factor of $\sim$4 in the N-band compared to standard VISIR for a given S/N and time. In this work we achieve a detection sensitivity of sub-mJy, which is sufficient to detect few Jupiter mass planets in nearby systems. Although no detections are made we achieve most sensitive limits within $<2''$ for all the observed targets compared to previous campaigns. For $ε$ Indi A and $ε$ Eri we achieve detection limits very close to the giant planets discovered by RV, with the limits on $ε$ Indi A being the most sensitive to date. Our non-detection therefore supports an older age for $ε$ Indi A. The results presented here show the promise for high contrast imaging and exoplanet detections in the mid-IR regime.

The Introduction of “Anti-Racist Legislation” in the Greek Legal Order: Political Strategies, Legalised Violence and the Formal Protection of Gender Identity.
Creators: name: Kasapidou, Roussa
Publisher: name: feminists@law
Year: 2021

description: The present article follows the introduction of the much-contested “anti-racist legislation” during a particularly dark era of governance in Greece. Within a context of deepening crisis, absolute legitimation of state racism and institutional violence against the nation’s racial, gender, religious and sexual Others, the politico-legal choice of a right-wing government to go through with this reform appears paradoxical at first glance. Even more so, the introduction of gender identity among the protected characteristics seems at odds not only with governmental actions that have directly targeted trans individuals but also with the overall gender-normative imperative of the law and the hostile institutional atmosphere that mirrors and reproduces it. In view of this seemingly paradoxical legislative choice, queried here is the concrete work performed by the “anti-racist law” reform in the context in which it unfolded. Utilising a broader problematisation of any legal regime’s authority to justify its own violence, it is suggested that a closer reading of the conditions under which the reform took place brings into light its instrumentalisation, during that era, to legitimise systemic racism and institutional gender/sexual violence materialised through operations against marginalised populations.

description: Little cigars or cigarillos (LCCs) are frequently modified to smoke cannabis (“blunts”) by youth and young adults. This study investigated whether young blunt users who are otherwise nicotine-naïve are more likely to initiate other tobacco products compared to never blunt users. Data were from four waves of the Truth Longitudinal Cohort (TLC), a national probability-based sample of youth and young adults (aged 15-24 years) in the United States (Wave 1: January—April 2017; Wave 2: February—May 2018; Wave 3: February—May 2019; Wave 4: September—December 2019). The sample was restricted to nicotine naïve respondents at Wave 1 with possible ever use of blunts (N = 5,284). Logistic regression analyses tested whether ever blunt use at Wave 1 predicted initiation of nicotine products by Wave 4, controlling for established risk factors. Compared to never-blunt users, ever users of blunts at Wave 1 had significantly higher odds of ever using cigars (OR: 4.74; 95% CI: 1.80-12.47; p = 0.002), e-cigarettes (OR: 4.66; 95% CI: 2.42-8.95; p < 0.001), cigarettes (OR: 3.02; 95% CI: 1.17-7.84, p = 0.023), or hookah (OR: 3.47; 95% CI: 1.07-11.29, p = 0.039) by Wave 4. Cannabis (never blunt) use by Wave 1 predicted ever use of e-cigarettes (OR: 3.45, 95% CI: 2.38-5.02, p < 0.001), cigarettes (OR: 3.81; 95% CI: 2.26-6.43, p < 0.001), or hookah (OR: 2.13; 95% CI: 1.12-4.05, p = 0.021) by Wave 4. Blunts are a point of nicotine initiation that places users at increased risk of progression to cigars, while the same relationship was not found for cannabis alone.

description: The design and implementation of sustainable processes, which are not dependent on fossilfuels, represents a significant challenge in the coming years [1]. However, biocatalytic processesbased on one enzymatic step limit the potential range of molecules that can be produced. Aclear trend is emerging towards the development of new and sophisticated biocatalyticcascades, which will replace single-step enzymatic transformations, allowing a cost-effectiveproduction of complex molecules while expanding the range of compounds that can beenzymatically obtained. However, further progress is required to industrially implement thesesystems such as improvements in process metrics, robustness and flexibility. In addition, areduction in the biocatalysts production costs is also required to enhance the techno-economicfeasibility of the processes.

The group of Bioprocess Engineering and Applied Biocatalysis aims to address thesechallenges through the economic and sustainability-oriented design, preparation, andimplementation of biocatalysts. This goal is achieved through the implementation of anintegrated and multidisciplinary approach, involving the production, thepurification/immobilization of enzymes in a single step [2], as well as the design of self-sufficient biocatalysts for their use in enzymatic reactors.

description: Although studies have demonstrated that the use of lysergic acid diethylamide (LSD) is on the rise in the United States, it remains unclear how this trend looks across the hierarchical ladder of the American workforce. This is relevant given that LSD is increasingly being touted as a means of boosting creativity and performance, with mounting anecdotal evidence that business managers in particular are turning to it for inspiration and insight. Using pooled cross-sectional data from the National Survey on Drug Use and Health (2006–2014) on 168,920 adults in the United States employed full-time (weighted = 117,270,940), this study investigates how temporal trends in past year LSD use differ among business managers and non-managers. The results suggest that the prevalence of past year LSD use increased over time at a greater rate among business managers than non-managers and that this difference cannot be accounted for by changes in business managers’ perceived risk of LSD use or general substance use relative to non-managers. The study’s findings indicate that temporal trends in past year LSD use depend on employees’ hierarchical rank in their organization and suggest that business managers, regardless of gender, are becomingly increasingly interested in the potential competitive advantages that LSD may offer.

description: The detection of a wide range of substructures such as rings, cavities and spirals has become a common outcome of high spatial resolution imaging of protoplanetary disks, both in the near-infrared scattered light and in the thermal millimetre continuum emission. The most frequent interpretation of their origin is the presence of planetary-mass companions perturbing the gas and dust distribution in the disk (perturbers), but so far the only bona-fide detection has been the two giant planets around PDS 70. Here, we collect a sample of 15 protoplanetary disks showing substructures in SPHERE scattered light images and present a homogeneous derivation of planet detection limits in these systems. We also estimate the mass of these perturbers through a Hill radius prescription and a comparison to ALMA data. Assuming that one single planet carves each substructure in scattered light, we find that more massive perturbers are needed to create gaps within cavities than rings, and that we might be close to a detection in the cavities of RX J1604, RX J1615, Sz Cha, HD 135344B and HD 34282. We reach typical mass limits in these cavities of 3-10 Mjup. For planets in the gaps between rings, we find that the detection limits of SPHERE are about an order of magnitude away in mass, and that the gaps of PDS 66 and HD 97048 seem to be the most promising structures for planet searches. The proposed presence of massive planets causing spiral features in HD 135344B and HD 36112 are also within SPHERE's reach assuming hot-start models.These results suggest that current detection limits are able to detect hot-start planets in cavities, under the assumption that they are formed by a single perturber located at the centre of the cavity. More realistic planet mass constraints would help to clarify whether this is actually the case, which might point to perturbers not being the only way of creating substructures.

description: An array of Neutral-Current Detectors (NCDs) has been built in order to make a unique measurement of the total active flux of solar neutrinos in the Sudbury Neutrino Observatory (SNO). Data in the third phase of the SNO experiment were collected between November 2004 and November 2006, after the NCD array was added to improve the neutral-current sensitivity of the SNO detector. This array consisted of 36 strings of proportional counters filled with a mixture of $^3$He and CF$_4$ gas capable of detecting the neutrons liberated by the neutrino-deuteron neutral current reaction in the D$_2$O, and four strings filled with a mixture of $^4$He and CF$_4$ gas for background measurements. The proportional counter diameter is 5 cm. The total deployed array length was 398 m. The SNO NCD array is the lowest-radioactivity large array of proportional counters ever produced. This article describes the design, construction, deployment, and characterization of the NCD array, discusses the electronics and data acquisition system, and considers event signatures and backgrounds.

description: The epsilon-enlargement of a maximal monotone operator is a construct similar to the Brøndsted and Rocakfellar epsilon-subdifferential enlargement of the subdifferential. Like the epsilon-subdifferential, the epsilon-enlargement of a maximal monotone operator has practical and theoretical applications. In a recent paper in Journal of Convex Analysis Burachik and Iusem studied conditions under which a maximal monotone operator is non-enlargeable, that is, its epsilon-enlargement coincides with the operator. Burachik and Iusem studied these non-enlargeable operators in reflexive Banach spaces, assuming the interior of the domain of the operator to be nonempty. In the present work, we remove the assumption on the domain of non-enlargeable operators and also present partial results for the non-reflexive case.

An analysis of adult education in libraries and museums
Creators: name: Crawford, Jennifer
Publisher: name: University of British Columbia

description: One of the characteristics of adult education is the degree to which it is dispersed throughout society. Much adult education is practiced in organizations and institutions that have purposes other than adult education. Schroeder (1970, p. 37) has suggested a category of adult education agencies (Type III agencies) established to serve both the educational and non-educational needs of the community, agencies in which "adult education is an allied function employed to fill only some of the needs which agencies recognize as their responsibility." The purpose of this study was to examine adult education in Schroeder's Type III agencies using libraries and museums as examples. The study addressed the definition and description of adult education, the importance of adult education relative to other functions of the organization, and the purposes for which the organizations used adult education. A comparative analysis of the adult education function of three libraries and three museums was conducted. Print materials (annual reports and publicity brochures) and interviews with the person responsible for programming were used as data sources. Analysis of the findings was done in three stages: single case analysis (within case analysis), analysis of libraries and museums (within category analysis), and comparison of libraries and museums (across category analysis). Many definitions of adult education were found. Most described the purposes of adult education rather than the process of teaching and learning. It was also found that the importance of adult education varied among the organizations studied. Adult education was less important than other organizational functions in four of the six organizations studied. It was as important as other functions in one organization and was not ranked in one organization. Five uses for adult education were found: stimulation (encouraging better use of the library or museum), enrichment (adding extra information), extension (enlarging community contacts), service (filling a social need), and advocacy (promoting social change). Generally, libraries used programming for extension and museums used it for enrichment. This study has contributed to understanding adult education in Type III organizations by describing some ways non-professional adult educators view adult education. It has also suggested some contextual factors that influence the adult education function in those organizations and has suggested a variety of purposes for which adult education could be used.
