title: Canopy Structure and Phenology of Alpine Tundra Vegetation
Creators: name: Fareed, Marcee
Publisher: name: Utah State University
Year: 1972

description: An inclined point frame was used to measure leaf area indicies in an alpine tundra Kobresia stand and Deschampsia meadow on Niwot Ridge, Colorado. Measurements were made throughout the summer of 1971 at vi various heights in the canopy and for each species in the two communities. Maximum leaf area indices of 2.2 and 2.0 occurred in the Kobresia and Deschampsia sites, respectively. The Kobresia site was characterized by a single dominant species, Kobresia myosuroides, and a predominance of vegetation within 2.5 cm of mean ground level. The Deschampsia site had no single dominant species. The region of maximum foliage shifted from the 2.5 to 5 cm height zone in June to the 5 to 10 cm zone in early August. Phenological observations revealed a greater number of vegetative contacts in the Deschampsia site on all sampling dates. Certain shared species varied in their phenological patterns. It is suggested that differences in the duration of snow cover and surface melt-water may be related to the variation in phenological patterns in the two sites. In both communities, maximum LAI occurred when flower and fruit production overlapped. Arctic tundra LAI values, measured using similar methods, were less than half the maximum LAI values reached in the alpine communities examined here.

description: Recommender system is an applicable technique in most E-commerce commercial product technical designs. However, nearly all recommender system faces a challenge called the cold-start problem. The problem is so notorious that almost every industrial practitioner needs to resolve this issue when building recommender systems. Most cold-start problem solvers need some kind of data input as the starter of the system. On the other hand, many real-world applications place popular items or random items as recommendation results. In this paper, we propose a new technique called ZeroMat that requries no input data at all and predicts the user item rating data that is competitive in Mean Absolute Error and fairness metric compared with the classic matrix factorization with affluent data, and much better performance than random placement.

Barriers to psychological treatment for mental illness among people who use illicit drugs
Creators: name: Beckley, RA
Publisher: name: University Of Tasmania
Year: 2023

description: The connection between illicit drug use and mental health is well understood, however, individuals who use illicit drugs seek professional help for their mental health at a lower rate than the general population. The aims of this study were to identify if people who use illicit drugs seek psychological help and subsequently explore the barriers experienced. The outcomes of the study were then used to provide recommendations to psychological services to improve access and satisfaction. Australians (n=140) aged 18 or above, all who had used an illicit drug in the past 12 months and reported concerns about their mental health completed an online survey addressing their experiences with psychological services and the aspects of psychological services that they were satisfied with or dissatisfied with. Participants responded to a series of statements addressing barriers to seeking and accessing psychological services and recommendations to assist in improving them. Survey results were analysed using descriptive statistics. Respondents identified that structural barriers of cost and availability were the most problematic. This was followed by personal barriers including mental health preventing attendance, previous poor experiences and perceived judgements of psychologists. In addition, participants reported feeling stigmatised due to their illicit drug use. Findings indicate the need for increasing education of psychologists regarding illicit drugs and the interaction with mental health problems or symptoms. Further, findings suggest recommendations for increasing education for people who use illicit drugs about psychology and psychotherapy, specifically informed consent, confidentiality, and the differences between mental health providers.

description: Matrix factorization is a widely adopted recommender system technique that fits scalar rating values by dot products of user feature vectors and item feature vectors. However, the formulation of matrix factorization as a scalar fitting problem is not friendly to side information incorporation or multi-task learning. In this paper, we replace the scalar values of the user rating matrix by matrices, and fit the matrix values by matrix products of user feature matrix and item feature matrix. Our framework is friendly to multitask learning and side information incorporation. We use popularity data as side information in our paper in particular to enhance the performance of matrix factorization techniques. In the experiment section, we prove the competence of our method compared with other approaches using both accuracy and fairness metrics. Our framework is an ideal substitute for tensor factorization in context-aware recommendation and many other scenarios.

description: Previous formulations of heating and transport associated with strong magnetohydrodynamic (MHD) turbulence are generalized to incorporate separate internal energy equations for electrons and protons. Electron heat conduction is included. Energy is supplied by turbulent heating that affects both electrons and protons, and is exchanged between them via collisions. Comparison to available Ulysses data shows that a reasonable accounting for the data is provided when (i) the energy exchange timescale is very long and (ii) the deposition of heat due to turbulence is divided, with 60% going to proton heating and 40% into electron heating. Heat conduction, determined here by an empirical fit, plays a major role in describing the electron data.

description: This study coupled the theory of uncertainty management (TUM) with the notion of transformational leadership (TFL) to examine how the uncertainty over the adoption of artificial intelligence (AI) technologies affects employees. SEM analyses with two-wave data collected in Japan (N = 1318 employee–supervisor dyads) revealed that uncertainty is negatively associated and TFL is positively associated with employees’ job performance. In addition, consistent with TUM, the digital literacy of leaders was found to moderate the effects of TFL such that the positive association between TFL and job performance disappeared when employees simultaneously feel high uncertainty and find supervisors low on digital literacy. These findings are discussed with reference to the relevant literature.

description: Recently, Greenfeld and Tao disprove the conjecture that translational tilings of a single tile can always be periodic [Ann. Math. 200(2024), 301-363]. In another paper [to appear in J. Eur. Math. Soc.], they also show that if the dimension $n$ is part of the input, the translational tiling for subsets of $\mathbb{Z}^n$ with one tile is undecidable. These two results are very strong pieces of evidence for the conjecture that translational tiling of $\mathbb{Z}^n$ with a monotile is undecidable, for some fixed $n$. This paper shows that translational tiling of the $3$-dimensional space with a set of $5$ polycubes is undecidable. By introducing a technique that lifts a set of polycubes and its tiling from $3$-dimensional space to $4$-dimensional space, we manage to show that translational tiling of the $4$-dimensional space with a set of $4$ tiles is undecidable. This is a step towards the attempt to settle the conjecture of the undecidability of translational tiling of the $n$-dimensional space with a monotile, for some fixed $n$.

description: Guided by structurational divergence (SD) theory, this study examined the presence and impact of unresolved tensions surrounding safety issues among hospital workers. Using a two-study design, data were gathered for Study 1 from focus groups and interviews involving 40 hospital employees at two hospitals. Thematic analysis indicated workers experienced SD-cycles marked by unresolved conflict, immobilization, and erosion of development. Study 2 surveyed (N = 303) workers within the same hospital network to examine the impact of unresolvable safety issues as both the outcome of SD and the antecedent to workers’ intent to leave. The conceptual model tested shows the destructive outcomes of SD on safety climate, where higher levels of SD lead to lower perceptions of safety climate.
title: Studies on mechanisms of Fcgamma receptor internalisation of antigen
Creators: name: Melville, Bryony Claire
Publisher: name: University of Glasgow
Year: 1998
Subjects: subject: Molecular biology

description: A differential pattern of tyrosine kinase phosphorylation for distinct FcgammaR signalling domains was defined in several ways. Firstly, Syk recruitment was observed in interferon gamma (IFNgamma) and dibutyl cAMP (DBC) treated U937 monocyte-like cells, upregulating FcgammaRI + gamma chain of the FcepsilonRI and FcgammaRII receptors respectively. IFNgamma cells showed peak Syk activation at 5-7 minutes post-activation, while DBC cells show an immediate increase in Syk recruitment. In addition, blots of post-activation lysates of the two cell types were probed with anti-phosphotyrosine antibody, revealing a strong band of 110kDa on both IFNgamma and DBC blots, and an unknown 50kDa band found exclusively on the DBC blot. Lastly, experiments designed to test whether or not the two cells types display alternative NO2 release patterns post-activation were established. In a second approach, a chimeric receptor was made by fusion of the extracellular region of FcgammaRI to the transmembrane and cytoplasmic tail of zeta chain. This chimeric receptor was then compared to other similarly constructed mutants, FcgammaRI-gamma and FcgammaRI-II for its ability to phagocytose sheep red blood cells (SRBC) in a well established phagocytosis experiment using COS-7 cells (a simian kidney fibroblast cell line). All mutants demonstrated relatively equivalent phagocytic ability in the COS-7 cell system. Select tyrosine kinases were then cotransfected with each mutant FcgammaR receptor. There was no marked difference in distinct tyrosine kinases hFyn, mLyn, and mSyk required by distinct internal tyrosine kinase activation motifs (ITAMs) for increasing phagocytic efficiency. However, it was discovered that the effect of the tyrosine kinase mSyk on FcgammaRI/gamma, FcgammaRI/zeta, and FcgammaRI/II internalisation was very significant, dramatically increasing both the number of COS-7 cells capable of phagocytosis and the number of SRBCs phagocytosed by each individual COS-7 cell.

description: Web grammars are a general and flexible method for "picture" description in computer graphics. They apply the rewriting procedure typical of string grammars to general directed graphs or "webs". An interactive graphical system is implemented to provide an easy and convenient way to manipulate and specify a web in a natural manner. This project is based on a system implemented by Pat Conroy. The system is written in ALGOLW. The graphical terminal used to display the webs is an Adage Graphical Terminal ( AGT for short ) which is connected to a main computer, an IBM 360/67 by telephone lines. There are instruments such as light-pen, function keys, foot pedals and dials to assist the interaction between the user and the AGT. In this project, a solution to the problem of replacing a subweb by another on the display screen is attemped.

title: The Influence of Roots on the Accuracy of Soil-Moisture Measurements Taken with a Neutron Moisture Meter
Creators: name: Andreessen, Terry L.
Publisher: name: Utah State University
Year: 1975

description: The effects of roots on soil-moisture measurements taken with a neutron probe were studied. These effects were observed under three different soil-moisture conditions, with different sized roots, and with varying distances between the access tube and root. The moisture conditions used were air dry, field capacity, and saturated.
Large roots can greatly affect neutron soil-moisture measurements when the access hole is drilled through the root. Positive errors as large as 52 percent were found when the soil moisture was at field capacity. With dry and saturated conditions positive errors of 43 percent and 38 percent respectively, were found.
In most practical field situations, where the access hole is not drilled through large roots, root material appears to have very little effect, if any, on neutron soil-moisture measurements. The largest positive error found, when the access holes were not drilled through the roots, was only 8 percent. This occurred at a point where the access tube was in contact with the outside of a root.

description: We demonstrate spin polarized tunneling from Fe through a SiO2 tunnel barrier into a Si n-i-p heterostructure. Transport measurements indicate that single step tunneling is the dominant transport mechanism. The circular polarization, Pcirc, of the electroluminescence (EL) shows that the tunneling spin polarization reflects Fe majority spin. Pcirc tracks the Fe magnetization, confirming that the spin-polarized electrons radiatively recombining in the Si originate from the Fe. A rate equation analysis provides a lower bound of 30% for the electron spin polarization in the Si at 5 K.

title: Competitive Interaction in Plant Populations Exposed to Enhanced UV-B Radiation
Creators: name: Fox, Fred M.
Publisher: name: Utah State University
Year: 1977

description: Competitive balance and changes in individual plant growth parameters of eight pairs of plant species exposed to enhanced UV-B irradiation were determined under field conditions simulating ozone reductions of about 0.08 atm·cm. The levels of irradiance represented ozone decreases of about 25-30 percent from approximate ambient ozone concentrations for high solar altitudes on clear days during the study. A method for calculating and statistically analyzing relative crowding coefficients was developed and used to evaluate the competitive status of the species pairs sown in a modified replacement series. The effect of UV-B irradiance was generally detrimental to plant growth, and was reflected in decreased leaf area, biomass, height and density as well as changes in competitive balance for various species. For some species inter-specific competition apparently accentuated the effect of UV-B radiation, while intensive intraspecific competition may have had the same effect for other species.

description: Prior research on expert collaborations has focused on how specialists – experts with deep domain knowledge – work across disciplinary boundaries with other specialists, with much less attention paid to how generalists – experts with broader and connective knowledge – work alongside specialists. To address this gap, we examined collaborative work requiring expertise of generalists (regional planners) and specialists (civil engineers). Our interview data revealed that privileged values of specialist expertise (i.e., exclusivity, neutrality, and feasibility) could close interpretive possibilities of their collaboration and that generalists engaged in communicative expertise positioning to make their expertise work with that of specialists. We developed a grounded model of generalist-specialist collaboration theorizing how they used discursive closures and openings to accentuate gains from their different expertise.

description: This study tested propositions of relational turbulence theory (RTT) from a latent variable mixture modeling perspective. A national sample of married individuals (N = 503) completed a questionnaire measuring RTT relationship parameters, experiences, and outcomes. A latent profile analysis provided support for RTT as (a) marriages were well-separated by relational uncertainty and interdependence parameters, (b) spouses belonging to marriages characterized by higher relational uncertainty and interference (and lower facilitation) experienced more biased cognitive appraisals and intensified negative emotions within the marriage, which in turn, (c) predicted relational turbulence. These results provide support for the specifications and mechanisms purported by RTT and offer an alternative person-centered, rather than traditional variable-centered, approach for testing its axioms and propositions.

description: Spatial correlation characteristics of the anomalous density matrix $κ$ in a slab of nuclear matter with the Paris and Argonne v18 forces are calculated. A detailed comparison with predictions of the effective Gogny force is made. It is found that the two realistic forces lead to very close results which are qualitatively similar to those for the Gogny force. At the same time, the magnitude of $κ$ for realistic forces is essentially smaller than the one for the Gogny force. The correlation characteristics are practically independent of the magnitude of $κ$ and turn out to be quite close for the three kinds of the force. In particular, all of them predict a small value of the local correlation length at the surface of the slab and a big one, inside. These results are in agreement with those obtained recently by Pillet at al. for finite nuclei with the Gogny force.

Evidence of finite coupling between the rows, resulting in bonding and antibonding states, is observed. At high dc source-drain bias, a structure is observed at 0.5(2e^2/h) due to parallel double-row transport, along with a structure at 0.25(2e^2/h), providing further evidence of coupling between the two rows.

description: By illuminating latent structures in a corpus of text, topic models are an essential tool for categorizing, summarizing, and exploring large collections of documents. Probabilistic topic models, such as latent Dirichlet allocation (LDA), describe how words in documents are generated via a set of latent distributions called topics. Recently, the Embedded Topic Model (ETM) has extended LDA to utilize the semantic information in word embeddings to derive semantically richer topics. As LDA and its extensions are unsupervised models, they aren't defined to make efficient use of a user's prior knowledge of the domain. To this end, we propose the Keyword Assisted Embedded Topic Model (KeyETM), which equips ETM with the ability to incorporate user knowledge in the form of informative topic-level priors over the vocabulary. Using both quantitative metrics and human responses on a topic intrusion task, we demonstrate that KeyETM produces better topics than other guided, generative models in the literature.

title: An Investigation of Internalizing Social-Emotional Characteristics in a Sample of Lakota Sioux Children
Creators: name: Williams, Michael Shawn
Publisher: name: Utah State University
Year: 1997

description: It has only been recently that research in childhood psychopathology has focused
on a group of disorders referred to as internalizing disorders. Internalizing disorders can
include such problems as depression. anxiety, social withdrawal, and somatic complaints.
Even though research has begun to focus on internalizing disorders with majority
children. there has been very little research conducted on ethnic minority children, Native
American children in particular.
The present study involved obtaining a Native American sample and determining
their internalizing symptomology utilizing the Internalizing Symptom Scale for Children
(ISSC), the Reynolds Child Depression Scale (RCDS), and the State Trait Anxiety
Inventory for Children (ST AIC). The study sample was compared to a matched
normative sample from the ISSC database. Statistical procedures included bivariate
correlations, analysis of variance (ANOV A), and discriminant function analysis.
Correlations between the ISSC and the two comparison measures (RCDS and ST AIC)
were in the expected direction and of moderate to strong magnitude. The total
internalizing symptoms scores of the Native American (Lakota Sioux) sample were
similar to those of a matched comparison group from the ISSC national normative database.
However, the study sample evidenced a unique pattern of responses on the ISSC
subscales, reporting lower rates of both internalizing distress and positive affect. Teacher
nominations of potential "internalizers" proved to be a poor predictor of their self-reported
symptoms. Implications of this study for clinical practice and future research
directions in this area are discussed.
title: Characteristics of Internalizing Social-Emotional Behaviors of Southwestern Native American Children
Creators: name: Morris, Carolyn Thomas
Publisher: name: Utah State University
Year: 1998

description: The knowledge base targeting internalizing symptomatology in Native American
children is surprisingly limited. As yet, it is not clear if the process and symptoms of
internalizing disorders are the same across cultures. The need for further investigation is
heightened by the fact that, compared to the majority population, Native Americans are
believed to be at greater risk for psychological problems because of impoverished conditions,
high unemployment, and high numbers of traumatic events on the reservations. Additionally,
the losses of traditional culture and language are considered risk factors for greater
psychopathology. The negative ramifications of internalizing disorders (e.g., depression and
anxiety) include academic failure, lowered social skills and self-esteem, and greater risk for
substance abuse and suicide. Furthermore, evidence suggests that all children with mental
disorders are at high risk for severe psychopathology when left unidentified or untreated. It
seems clear that additional research is needed to better understand internalizing symptoms
among members of this cultural group.
To help meet this need, the present study focused on internalizing disorders among
Native American children from the southwest, utilizing a portion of extant data from the
Flower of Two Soils Project. This project was one of very few methodologically sound studies
that have been successful in obtaining multisource. multimethod data on social, emotional, and
behavioral functioning of Native American children. Data were collected using a modified
version of the Child Behavior Checklist (CBCL), Youth Self-Report (YSR), and Teacher's
Report Form (TRF) assessment instruments for parents, teachers, and children.
Findings with respect to elementary school-aged children found relatively high rates of
depression, anxiety, somatization symptoms and, potentially, disorders. These findings are a
cause for concern among parents, teachers, and all agencies responsible for children's mental
health. Across all three informant groups a consistent pattern of negative correlations was
observed between internalizing symptoms and child competencies. This finding is consistent
with previous findings for the general population. However,. competitiveness and academic
achievement were positively correlated with internalizing symptoms, perhaps indicating that an
emphasis on competitiveness and individual achievement is stressful for children from a
collectivistic Native American culture.
This was a descriptive study providing broad exploratory information, but there
remains a need for more focused research identifying multivariate relationships among relevant
variables. These findings should be cautiously interpreted and with due consideration for the
specific cultural and historical context of children and families. Recommendations are included
for research and practice.

description: We present a study of the ionized, neutral atomic, and molecular gas associated with the ring nebula RCW 78 around the WR star HD 117688 (= WR 55). We based our study on CO observations carried out with the SEST and NANTEN telescopes. We report the detection of molecular gas with velocities in the range -56 to -33 km/s. The CO emission is mainly connected to the western section, with a total molecular mass of 1.3 x 10^5 solar masses. The analysis of the HI gas distribution reveals the HI envelope of the molecular cloud, while the radio continuum emission shows a ring-like structure, which is the radio counterpart of the optical nebula. The gas distribution is compatible with the western section of RCW 78 having originated in the photodissociation and ionization of the molecular gas by HD 117688, and with the action of the stellar winds of the WR star. A number of infrared point sources classified as YSO candidates showed that stellar formation activity is present in the molecular gas linked to the nebula. The fact that the expansion of the bubble have triggered star formation in this region can not be discarded.

description: Experimental tests of gravity's fundamental nature call for mechanical systems in the quantum regime while being sensitive to gravity. Torsion pendula, historically vital in studies of classical gravity, are ideal for extending gravitational tests into the quantum realm due to their inherently high mechanical quality factor, even when mass-loaded. Here, we demonstrate laser cooling of a centimeter-scale torsional oscillator to a temperature of 10 mK (average occupancy of 6000 phonons) starting from room temperature. This is achieved by optical radiation pressure forces conditioned on a quantum-noise-limited optical measurement of the torsional mode with an imprecision 9.8 dB below its peak zero-point motion. The measurement sensitivity is the result of a novel `mirrored' optical lever that passively rejects extraneous spatial-mode noise by 60 dB. The high mechanical quality ($1.4\times 10^7$) and quantum-noise-limited measurement imprecision demonstrate the necessary ingredients for realizing the quantum ground state of torsional motion -- a pre-requisite for mechanical tests of gravity's alleged quantum nature.

description: We propose a methodology for extracting concepts for a target domain from large-scale linked open data (LOD) to support the construction of domain ontologies providing field-specific knowledge and definitions. The proposed method defines search entities by linking the LOD vocabulary with technical terms related to the target domain. The search entities are then used as a starting point for obtaining upper-level concepts in the LOD, and the occurrences of common upper-level entities and the chain-of-path relationships are examined to determine the range of conceptual connections in the target domain. A technical dictionary index and natural language processing are used to evaluate whether the extracted concepts cover the domain. As an example of extracting a class hierarchy from LOD, we used Wikidata to construct a domain ontology for polymer materials and physical properties. The proposed method can be applied to general datasets with class hierarchies, and it allows ontology developers to create an initial model of the domain ontology for their own purposes.

description: Two-stage adaptive robust optimization (ARO) is a powerful approach for planning under uncertainty, balancing first-stage decisions with recourse decisions made after uncertainty is realized. To account for uncertainty, modelers typically define a simple uncertainty set over which potential outcomes are considered. However, classical methods for defining these sets unintentionally capture a wide range of unrealistic outcomes, resulting in overly-conservative and costly planning in anticipation of unlikely contingencies. In this work, we introduce AGRO, a solution algorithm that performs adversarial generation for two-stage adaptive robust optimization using a variational autoencoder. AGRO generates high-dimensional contingencies that are simultaneously adversarial and realistic, improving the robustness of first-stage decisions at a lower planning cost than standard methods. To ensure generated contingencies lie in high-density regions of the uncertainty distribution, AGRO defines a tight uncertainty set as the image of "latent" uncertainty sets under the VAE decoding transformation. Projected gradient ascent is then used to maximize recourse costs over the latent uncertainty sets by leveraging differentiable optimization methods. We demonstrate the cost-efficiency of AGRO by applying it to both a synthetic production-distribution problem and a real-world power system expansion setting. We show that AGRO outperforms the standard column-and-constraint algorithm by up to 1.8% in production-distribution planning and up to 11.6% in power system expansion.

description: Web search and other large-scale web data analytics rely on processing archives of web pages stored in a standardized and efficient format. Since its introduction in 2008, the IIPC's Web ARCive (WARC) format has become the standard format for this purpose. As a list of individually compressed records of HTTP requests and responses, it allows for constant-time random access to all kinds of web data via off-the-shelf open source parsers in many programming languages, such as WARCIO, the de-facto standard for Python. When processing web archives at the terabyte or petabyte scale, however, even small inefficiencies in these tools add up quickly, resulting in hours, days, or even weeks of wasted compute time. Reviewing the basic components of WARCIO and analyzing its bottlenecks, we proceed to build FastWARC, a new high-performance WARC processing library for Python, written in C++/Cython, which yields performance improvements by factors of 1.6-8x.

description: Tidal disruption events are possible sources of temporary nuclear activity in galactic nuclei and can be considered as good indicators of the existence of super massive black holes in the centers of galaxies. A new X-ray source has been serendipitously detected with ROSAT in a PSPC pointed observation of the galaxy cluster A3571. Given the strong flux decay of the object in subsequent detections, the tidal disruption scenario is investigated as possible explanationof the event. We followed up the evolution of the X-ray transient with ROSAT, XMM-Newton and Chandra for a total period of ~13 years. We also obtained 7-band optical/NIR photometry with GROND at the ESO/MPI 2.2m telescope. We report a very large decay of the X-ray flux of ROSAT source identified with the galaxy LEDA 095953 a member of the cluster Abell 3571. We measured a maximum 0.3-2.4 keV luminosity Log(L_X)=42.8 erg s^-1. The high state of the source lasted at least 150 ks, afterwards L_X declined as ~t^-2. The spectrum of the brightest epoch is consistent with a black body with temperature kT ~0.12 keV. The total energy released by this event in 10 yr was estimated to be Delta_E>2x10^50 erg. We interpret this event as a tidal disruption of a solar type star by the central supermassive black hole (i.e. ~10^7 M_sun) of the galaxy.

description: The centers of elliptical galaxies host supermassive black holes that significantly affect the surrounding interstellar medium through feedback resulting from the accretion process. The evolution of this gas and of the nuclear emission during the galaxies' lifetime has been studied recently with high-resolution hydrodynamical simulations. These included gas cooling and heating specific for an average AGN spectral energy distribution, a radiative efficiency declining at low mass accretion rates, and mechanical coupling between the hot gas and AGN winds. Here we present a short summary of the observational properties resulting from the simulations, focussing on 1) the nuclear luminosity; 2) the global luminosity and temperature of the hot gas; 3) its temperature profile and X-ray brightness profile. These properties are compared with those of galaxies of the local universe, pointing out the successes of the adopted feedback and the needs for new input in the simulations.

title: A Longitudinal Study of Attention-Deficit/Hyperactivity Disorder Symptoms in Preschool-Age Children

description: Attention-deficit hyperactivity disorder (ADHD) is among the most common reasons for
referral to children's mental health clinics, with an estimated prevalence of 3% to 5% in the
general population of school-age children. Children who exhibit the requisite behaviors may
obtain a diagnosis of ADHD at any age; however, symptom onset must occur before age 7 and
persist for at least 6 months. Despite these temporal requirements for diagnosis, little empirical
information about the manifestation and stability of ADHD symptoms in preschool children
exists. This study provides information about the initial presence and stability over one academic
year of ADHD behaviors in a sample of 290 preschool children rated by mothers and/or teachers.
Data suggest higher levels of these behaviors at home versus school, with behaviors remaining
stable over the course of the academic year at school, and diminishing over this time period at
home. Family environment factors (e.g., socioeconomic status, family stress) were not found to
have strong predictive relationships with levels of ADHD behaviors in this sample of
preschoolers including little support for a directional relationship between dysfunctional
parenting behaviors and child ADHD symptoms. Conclusions and clinical implications of these
finding, are provided and may assist psychologists in their efforts to diagnose and treat this
disorder in young children.
