description: The recovery process from cannabis use disorders has received little empirical attention. Understanding how and the ways in which individuals with cannabis use disorders recover may help to improve formal treatments and facilitate recovery for those who wish to not seek treatment. The present study was undertaken with two primary objectives in mind. The first primary objective was to provide an exploratory portrait of the recovery process from cannabis use disorders from the perspective of individuals who have recovered. The second primary objective was to explore and systematically describe the similarities and differences between abstinence- and moderation-oriented recoveries, as well as the similarities and differences between treatment-assisted and natural recoveries. The methodology was largely borrowed from the natural recovery literature insofar as recovery was first inferred via the remission of diagnostic symptoms, and then explored predominantly via several interview domains (e.g., reasons for resolution, actions taken to recover, maintenance factors, barriers to treatment seeking). Several interesting and important findings emerged at the level of the total sample (N = 119), as well as at the level of group comparisons between the different recovery pathways. Notably, the findings lend further support to the effectiveness of cognitive, motivational, and behavioural strategies as helpful actions and maintenance factors involved in the recovery process. The findings also generally support the idea that cannabis use disorders lie on a continuum of problem severity, with moderation-oriented and natural recoveries more likely to occur at the lower end of the continuum, and abstinence-oriented and treatment-assisted recoveries more likely to occur at the upper end. Moreover, both similarities and differences among the recovery pathways emerged with respect the recovery process. The findings are discussed in the context of the broader addictions literature and with respect to implications for policy and practice.
Supporting Bibliodiversity in Open Access Book Publishing: The Open Book Collective
Creators: name: Fathallah, Judith
Publisher: name: Zenodo
Year: 2023

description:
 The academic publishing landscape is dominated by a handful of major Western corporations. Thus, the Open Access landscape is increasingly imperilled by the processes of platform capitalism. This entrenches the dominance of wealthy academics and institutions from the Global North, the bias to English in academic publishing, and pressures academics in the Global South to neglect local issues for publication on issues of interest to a US and European audience (Okune 2019). Bibliodiversity, or the support and promotion of books in a variety of languages and local contexts, is thus a practical application of postcolonial thinking and decolonization. This presentation demonstrates how the Open Book Collective utilises an alternative publishing model we call "Scaling Small," in opposition to the neoliberal drive for monopoly and standardization, to collectively support and network a range of small to medium OA publishers from across the world, assisting them in moving away from the Book Processing Charges which can entrench inequities further.

description: Tau leptons play an important role in the physics program at the LHC. They are used in searches for new phenomena like the Higgs boson or Supersymmetry and in electroweak measurements. Identifying hadronically decaying tau leptons with good performance is an essential part of these analyses. We present the current status of the tau reconstruction and identification at the LHC with the ATLAS detector. The tau identification efficiencies and their systematic uncertainties are measured using W to tau nu and Z to tau tau events, and compared with the predictions from Monte Carlo simulations.

description: Multi-electrode arrays are non-invasive devices for neural stimulation in vivo and in vitro. Improving the efficiency of these devices is desired for stimulating neurons over extended periods of time. In this work, changing the geometry of the electrode used in the array is investigated. This approach will improve efficiency without requiring fundamental changes in the fabrication process, allowing for ease of implementation. A model is presented to study features that provide optimum stimulation threshold from different sizes and shapes of electrodes. Specially, a single neuron-electrode interface was modelled and cell depolarization generated by stimulating the cell by different electrode shapes were compared. The geometries investigated were star, spiral, serpentine, and circular electrode shapes. Based on the simulations, the electrode geometries were designed and then fabricated into a planar microelectrode array test device. Proof of principle in vitro experimentation was then conducted, with the results being compared to the simulations.
Modeling non-motorized travel demand at intersections based on traffic counts and GIS data in Calgary, Canada

Year: 2013
Subjects: subject: Engineering--Civil
subject: Transportation Engineering

description: In September 2009 the City of Calgary Council approved Plan It Calgary, which proposes policies that focus on the development of resilient neighborhoods through the intensification and diversification of urban activities around transit stations and routes. More intensive development and mixed land use encourage non-motorized trips and reinforce comfortable, safe and walkable streets. The development of high-density, mixed-use and transit- and pedestrian-oriented communities has the potential to generate trips with shorter destinations, which are expected to result in a higher share of active travel modes, such as biking and walking. Thus, there is a growing need to estimate the impact of land-use development scenarios and transportation policies on bicycle and pedestrian demand to predict future non-motorized trip volumes and adequately design the related infrastructure. This study calibrates multiple linear and Poisson regression models to estimate non-motorized travel demand based on GIS, transportation data and road characteristics. The empirical models that have been developed in this research can be used to assess the impacts of urban design and built environments, such as developing high-density and mix-land-use areas, and building complete streets in the middle ring communities of the City of Calgary in influencing the demand for active travel modes. The developed models show the benefits of improved pedestrian infrastructure, such as improved network connectivity and increases in the length of pedestrian pathways, as well as the integration of transit and walking modes and transit and bicycle modes in encouraging more non-motorized travel demand. The method employed herein is a straightforward statistical analysis method, and the needed data are relatively easy to access.

description: We study a combined sample of 264 star-forming, 51 composite, and 73 active galaxies using optical spectra from SDSS and mid-infrared (mid-IR) spectra from the Spitzer Infrared Spectrograph. We examine optical and mid-IR spectroscopic diagnostics that probe the amount of star formation and relative energetic contributions from star formation and an active galactic nucleus (AGN). Overall we find good agreement between optical and mid-IR diagnostics. Misclassifications of galaxies based on the SDSS spectra are rare despite the presence of dust obscuration. The luminosity of the [NeII] 12.8 μm emission-line is well correlated with the star formation rate (SFR) measured from the SDSS spectra, and this holds for the star forming, composite, and AGN-dominated systems. AGN show a clear excess of [NeIII] 15.6 μm emission relative to star forming and composite systems. We find good qualitative agreement between various parameters that probe the relative contributions of the AGN and star formation, including: the mid-IR spectral slope, the ratio of the [NeV] 14.3 μm to [NeII] μm 12.8 fluxes, the equivalent widths of the 7.7, 11.3, and 17 $μm$ PAH features, and the optical "D" parameter which measures the distance a source lies from the locus of star forming galaxies in the optical BPT emission-line diagnostic diagram. We also consider the behavior of the three individual PAH features by examining how their flux ratios depend upon the degree of AGN-dominance. We find that the PAH 11.3 μm feature is significantly suppressed in the most AGN-dominated systems.

description: Heegaard Floer theory is a kind of topological quantum field theory, assigning graded groups to closed, connected, oriented 3-manifolds and group homomorphisms to smooth, oriented 4-dimensional cobordisms. Bordered Heegaard Floer homology is an extension of Heegaard Floer homology to 3-manifolds with boundary, with extended-TQFT-type gluing properties. In this survey, we explain the formal structure and construction of bordered Floer homology and sketch how it can be used to compute some aspects of Heegaard Floer theory.

Our approach integrates three core components: (1) Pindola, a modern transformer-based bidirectional encoder pretrained on a large corpus of Classical Chinese texts; (2) a retrieval module that fetches relevant external context for each target sequence; and (3) a generative reasoning step that summarizes retrieved context in Classical Chinese for more robust entity disambiguation. Using this approach, we achieve an average F1 score of 85.58, improving upon the competition baseline by nearly 5 points.

description: The electron-cyclotron maser emission from electron holes is applied to holes generated in the downstream current region of the aurora. We suggest that part of the fine structure observed in the auroral kilometric radiation is generated by the electron-cyclotron maser mechanism in the downstream current region. The argument goes that the main background auroral kilometric radiation source is still located in the partial electron ring (horseshoe) distribution of the upward current region while the fine structure is caused by electron holes generated predominantly in the downward current region. Since both regions always exist simultaneously they are acting in tandem in generating auroral kilometric radiation by the same mechanism though in different ways.

description: Abstract – IT Sulla base di un approccio antropologico, l’incontro terapeutico verrà ripensato come un processo di produzione partecipativa del significato della realtà, capace di promuovere una rielaborazione dell’esperienza di malattia, consentendo inoltre l’individuazione di possibili forme di intervento capaci di generare socialmente tale trasformazione. Introducendo il concetto di “diritto al significato” come terreno per l’individuazione di quali altri diritti promuovere, il concetto di efficacia terapeutica verrà ripensato in termini di trasformazione: non solo nei termini delle possibili trasformazioni sul piano anatomico-fisiologico che le tecniche di intervento biomedico possono realizzare; non solo nei termini delle trasformazioni nei rapporti di senso che la relazione di cura incentrata sul diritto al significato può promuovere; ma anche nei termini di una trasformazione dei rapporti sociali in cui i pazienti sono coinvolti. Abstract – EN In anthropological terms the therapeutic encounter will be reconsidered as a process of participatory production of the meaning, promoting a reformulation of the experience of illness and allowing the identification of possible forms of intervention capable of socially generating such a reformulation. The concept of “right to meaning” as a basis for the identification of other rights helps us to reframe the issue of therapeutic efficacy. The latter will be reconsidered through the concept of transformation, not only in terms of the possible transformations on the anatomo-physiological plane that can be performed by biomedical intervention, or in terms of the changes in the relationships of meaning that the right to meaning can promote, but also in terms of a transformation in the patients’ social relationships.

description: This study examines challenges associated with the implementation of Transit Oriented Development (TOD) Station Area Communities (SAC) in Calgary, Canada. It defines the Community Planning Process (CPP) as a cycle with five stages: Vision, Plans, Implementation, Evaluation and Feedback where the communication of Evaluation outcomes (Feedback) loops back to inform the next cycle and improve future physical and functional outcomes. The research takes a two-pronged approach: (1) SWOT Analysis of Calgary’s municipal practice within the CPP with respect to TOD which includes a review of the literature, a review of Calgary’s city-level TOD policy and interviews with key informants to assess implementation gaps; and (2) Development and implementation of a TOD Community Evaluation Framework (CEF) which is informed by a review of the literature, a review of Calgary’s local-level TOD policy and participant observation in order to determine the level of success of TOD SACs. The CEF defines five evaluation categories: Intensity, Key Elements, Pedestrian Focus, Mix of Uses and Place and was used to analyze three Calgary SACs: Bridgeland, Sunnyside and Westbrook. Within Calgary’s municipal practice, it was found that community evaluation and feedback are often overlooked altogether. At the local level, Intensity, Mix of Uses and Place categories score consistently lower across the case study communities. It is recommended that the City implement a community evaluation system that provides feedback to decision makers within the CPP and that implementation efforts focus on attracting residents and jobs while encouraging mixed use projects and place-making efforts.
Fragmentation and monomer lengthening of rod-like polymers, a relevant model for prion proliferation

description: The Greer, Pujo-Menjouet andWebb model [Greer et al., J. Theoret. Biol., 242 (2006), 598-606] for prion dynamics was found to be in good agreement with experimental observations under no-flow conditions. The objective of this work is to generalize the problem to the framework of general polymerization-fragmentation under flow motion, motivated by the fact that laboratory work often involves prion dynamics under flow conditions in order to observe faster processes. Moreover, understanding and modelling the microstructure influence of macroscopically monitored non-Newtonian behaviour is crucial for sensor design, with the goal to provide practical information about ongoing molecular evolution. This paper's results can then be considered as one step in the mathematical understanding of such models, namely the proof of positivity and existence of solutions in suitable functional spaces. To that purpose, we introduce a new model based on the rigid-rod polymer theory to account for the polymer dynamics under flow conditions. As expected, when applied to the prion problem, in the absence of motion it reduces to that in Greer et al. (2006). At the heart of any polymer kinetical theory there is a configurational probability diffusion partial differential equation (PDE) of Fokker-Planck-Smoluchowski type. The main mathematical result of this paper is the proof of existence of positive solutions to the aforementioned PDE for a class of flows of practical interest, taking into account the flow induced splitting/lengthening of polymers in general, and prions in particular.

Social participation, quality of life and attendance at brain injury drop-in centres : an exploration study
Creators: name: McLean, Alison May
Publisher: name: University of British Columbia
Year: 2010

description: Introduction: Many individuals with traumatic brain injury (TBI) experience long term or life-long changes in social participation and quality of life, including social isolation, loneliness, reduced involvement in social and leisure activities, decreased social support networks and reduced satisfaction with life. There are few community-based interventions available to address these issues, and little research on their effectiveness. The brain injury drop-in centre (BIDC) is an innovative model of long-term support not yet addressed in the literature. Purpose: (a) To determine if there is a relationship between social participation and subjective quality of life (SQOL) for community-dwelling individuals with TBI. (b) To compare social participation and SQOL for individuals with TBI who attend BIDCs with individuals who do not attend but who have been identified as potentially benefitting from attending. Methods: Subjects. Participants were 23 individuals recruited from BIDCs (‘BIDC group’) and 19 individuals recruited through community-based clinicians and service providers (‘Comparison group’). The Comparison group was found to consist of 7 participants who stated that maybe they would attend a BIDC but for the most part were too busy to attend (‘Maybe group’), and 12 participants who stated that yes they would attend but were not aware of BIDCs or experienced a contextual barrier to attendance (‘Yes group’). Design. A cross sectional design was implemented with convenience sampling. Results: The correlational analysis (Chapter Two) showed statistically significant associations involving SQOL and the social and subjective measures of social participation. The comparison study (Chapter Three) found the BIDC group to have, on average, higher levels of SQOL and social participation than the Comparison group, in particular as compared to the Yes group. Conclusions: This exploratory study contributes to the TBI literature in showing that it is the more subjective and not objectively measured nature of participation that is associated with SQOL. Findings provide tentative support that attendance at BIDCs may benefit social participation and SQOL. This study provides a foundation for more rigorous quantitative investigation of the effectiveness and efficacy of BIDCs, as well as direction for qualitative studies to further explore social participation, SQOL and the experience of attending BIDCs.

description: Abstract – IT Il bharata natyam, stile coreutico dell’India meridionale, viene generalmente considerato una danza tradizionale che ha mantenuto immutate nel tempo le proprie caratteristiche contenutistiche e formali. In realtà questo stile proviene da una danza precedente, il sadir, alla quale sono state apportate profonde trasformazioni dalla riformatrice Rukmini Devi. Nel passaggio dal sadir al bharata natyam vi è stata la sostituzione di un gruppo di specialisti di tradizione ereditaria con musicisti e danzatrici appartenenti a caste elevate, l’eliminazione di brani coreografici considerati eccessivamente erotici, il passaggio dal tempio al teatro nell’esecuzione delle performance, e infine l’introduzione di Shiva Nataraja come dio patrono della danza e come soggetto delle coreografie. Abstract – EN Bharata natyam, a dancing style from southern India, is commonly regarded as a traditional dance that preserved its features of content and form through time. Actually it takes its origins from a former dance, sadir, profoundly altered by the reformer Rukmini Devi. She replaced the hereditary specialized musicians and dancers with upper-cast performers, removed the most erotic choreographies from the repertory, moved the setting from the temple to the public stage and introduced Shiva Nataraja both as patron and topic of the dance.

description: During DNA replication in Borrelia burgdorferi, replication of linear elements results in an inverted dimer repeat of the telomere which is subsequently resolved by the telomere resolvase, ResT. ResT has been demonstrated as essential and a knock-out strain has never been produced. Using a conditional expression system a resT knock-out strain has been produced and used to investigate the effects of ResT depletion of spirochete viability as well as genome stability. ResT depleted spirochetes ceased to divide after ResT depletion, however, remained viable up to 16 days suggesting an arrested state of the spirochetes. Southern blots of the DNA revealed a shift of linear plasmid DNA to a higher molecular weight representing the circular intermediate. DNA replication did not continue in spirochetes after ResT depletion suggesting ResT may play a larger role in replication than previously thought.

description: We propose a "guide" towards quantisation of gravity based on quantum matter in a statistical mechanics context. On one hand, a statistical mechanics model naturally arises from the thermodynamic interpretation of horizons in Rindler space. On the other hand, the path integral formulation of quantum field theory can be interpreted from the point of view of statistical mechanics. From these perspectives, gravity and matter are related to each other in the same way as a gas and its chemical potential are. This statistical mechanics interpretation of gravity and matter suggests that gravity should be quantised in a precise way which is determined by the quantisation of matter. Although, in a first step, quantisation of gravity applies for small perturbations of the metric with respect to the vacuum, the most central and general features of quantisation (quantisation prescription, quantum space dimensions) are supported from statistical mechanics and remain valid non-perturbatively.

description: The vasoactive factors angiotensin II (ANG II) and nitric oxide (NO), and the balance between them play a major role in regulating cardiovascular and electrolyte homeostasis. During the perinatal period, both factors are elevated, yet their physiological roles have not been clearly defined. Furthermore, the temporal and spatial expression of the receptors for ANG II (AT1Rs and AT2Rs) is developmentally regulated, although their physiological roles are also unknown. The present study aimed to elucidate for the first time, the physiological effects of ANG II on the kidney during postnatal maturation, as well as the potential role of the ATRs in initiating these physiological effects. In addition, this study investigated for the first time the interaction between ANG II and NO in regulating cardiovascular and renal function during the period of adaptation of the newborn to life after birth. Two study protocols were carried out in conscious lambs at two stages of postnatal maturation - one and six weeks. The first protocol evaluated (a) the individual functions of ATRs and (b) any possible interaction between them in mediating haemodynamic and renal physiological responses of ANG II. The second protocol investigated the roles of ATRs in modulating physiological roles of endogenoulsy produced NO during development. Results from these experiments show for the first time, that there does not appear to be any interaction between AT1Rs and AT2Rs in mediating haemodynamic effects of endogenous ANG II early in life. In contrast, the renal effects of ANG II are mediated through AT1Rs in an age-dependent manner, whereas AT2Rs buffer these effects. My research also shows for the first time, that ANG II modulates the effects of NO on renal haemodynamics and function but not systemic haemodynamics in an age-dependent manner through activation of AT1Rs and AT2Rs. Furthermore, it appears that AT2Rs interact with AT1Rs in mediating the renal effects of NO in developing newborn animals. This is the first description of renal effects of ANG II and a new and important interaction between ANG II and NO under physiological conditions early in life.

description: This paper introduces an approach to process channel sounder data acquired from Channel Impulse Response (CIR) of 60GHz and 80GHz channel sounder systems, through the integration of Long Short-Term Memory (LSTM) Neural Network (NN) and Fully Connected Neural Network (FCNN). The primary goal is to enhance and automate cluster detection within peaks from noised CIR data. The study initially compares the performance of LSTM NN and FCNN across different input sequence lengths. Notably, LSTM surpasses FCNN due to its incorporation of memory cells, which prove beneficial for handling longer series.Additionally, the paper investigates the robustness of LSTM NN through various architectural configurations. The findings suggest that robust neural networks tend to closely mimic the input function, whereas smaller neural networks are better at generalizing trends in time series data, which is desirable for anomaly detection, where function peaks are regarded as anomalies.Finally, the selected LSTM NN is compared with traditional signal filters, including Butterworth, Savitzky-Golay, Bessel/Thomson, and median filters. Visual observations indicate that the most effective methods for peak detection within channel impulse response data are either the LSTM NN or median filter, as they yield similar results.

description: As a significant factor in urban planning, traffic forecasting and prediction of epidemics, modeling patterns of human mobility draws intensive attention from researchers for decades. Power-law distribution and its variations are observed from quite a few real-world human mobility datasets such as the movements of banking notes, trackings of cell phone users' locations and trajectories of vehicles. In this paper, we build models for 20 million trajectories with fine granularity collected from more than 10 thousand taxis in Beijing. In contrast to most models observed in human mobility data, the taxis' traveling displacements in urban areas tend to follow an exponential distribution instead of a power-law. Similarly, the elapsed time can also be well approximated by an exponential distribution. Worth mentioning, analysis of the interevent time indicates the bursty nature of human mobility, similar to many other human activities.

Year: 2013
Subjects: subject: Education--Business
subject: Information Systmes

description: As Information Technology (IT) continues to be a major driving force for innovation, productivity, and economic growth, it is still crucial to understand how IT affects and transforms firms and industries - the benefits it creates as well as the risks it causes. This dissertation consists of three essays, and explores the nature and value of IT, as a production input, as an event that may contain informational content, and as an investment decision that can change firms' risk profiles. The first essay discusses IT's contribution to productive capacity - the maximum sustainable level of output that a production unit may achieve by increasing its short-run inputs to a limit. The second essay examines the informational nature of IT investment announcements - whether they provide new information to investors. The third essay investigates the risky nature of IT investment announcements - how they affect firm risk perceived by investors.

description: Zirconolite, CaZrTi2O7, is a proposed ceramic for the use in disposal of highly active nuclear waste. Density functional theory (DFT) has been used, in conjunction with a random search technique, to identify the stable interstitial sites for the intrinsic defects in zirconolite. There is a significant dependence on charge states for the vacancy defect structures, with the formation of an O2 molecule in certain charge states of Ti and Zr vacancies. The low coordination of the oxygen ions provided sites on which DFT localised holes associated with the cation vacancies. The Frenkel defect energies, calculated from the combination of the vacancy and interstitial formation energies, show that the oxygen defects have a strong dependence on the chemical environment, with a range of 1.5 eV between the oxygen Frenkel pair energies.

description: The accuracy of the training data limits the accuracy of bulk properties from machine-learned potentials. For example, hybrid functionals or wave-function-based quantum chemical methods are readily available for cluster data but effectively out-of-scope for periodic structures. We show that local, atom-centred descriptors for machine-learned potentials enable the prediction of bulk properties from cluster model training data, agreeing reasonably well with predictions from bulk training data. We demonstrate such transferability by studying structural and dynamical properties of bulk liquid water with density functional theory and have found an excellent agreement with experimental as well as theoretical counterparts.
Purging the past : Palma Sola, Trujillo, and the salvation of the Dominican nation
Creators: name: Mooney, Kathrine Erin
Publisher: name: University of British Columbia
Year: 2010

description: This essay examines the rise of Palma Sola, a religious community in the south-west region of the Dominican Republic, in the wake of the assassination of the long-reigning dictator, Rafael Leónidas Trujillo. The focus of the thesis is on the divergent narratives produced within the community at Palma Sola and those produced by actors in the capital, leading up to an armed intervention by state forces at the end of December 1962. A central argument is made that, despite very different viewpoints on the significance and function of Palma Sola, both narratives evince a concern with reorganizing the meaning of the dictatorial past, and a desire to chart a path toward a more auspicious future. Throughout, this paper suggests that practice must be examined alongside discourses and symbols in historical explorations of culture. Further, it argues that relying on oversimplified definitions of “religion” and the “nation” can be misleading, for it disallows an analysis that can locate the conjoined roots of these divergent narratives.

description: We propose a machine learning method to model molecular tensorial quantities, namely the magnetic anisotropy tensor, based on the Gaussian-moment neural-network approach. We demonstrate that the proposed methodology can achieve an accuracy of 0.3--0.4 cm$^{-1}$ and has excellent generalization capability for out-of-sample configurations. Moreover, in combination with machine-learned interatomic potential energies based on Gaussian moments, our approach can be applied to study the dynamic behavior of magnetic anisotropy tensors and provide a unique insight into spin-phonon relaxation.

description: Operation of a water treatment plant (WTP) requires understanding of treatment technology and how operations are affected by source water quality. Small WTPs generally rely on less experienced operators who may not be able to adapt to the changing conditions, or quickly identify problems. A decision support system (DSS) was developed for small WTPs to assess the treatment of microbial pathogens with common treatment technologies. The DSS includes fault trees, performance functions, quantitative microbial risk assessment, and data management capabilities in an integrated spreadsheet (Excel based) tool that could be coupled with an existing SCADA system. The utility of the DSS was evaluated based on eight case-studies using data from small WTPs in Alberta. It was determined that the DSS was able to effectively identify poorly performing WTPs that inadequately treat source water. Implementation of the DSS into an operating WTP is required to determine whether this tool can be utilized by operators in real world applications.

description: Blood flow control is dependent upon the initiation of electrical signals and their conduction along the arterial wall. The distance over which electrical phenomena conduct is governed by gap junctions and membrane resistivity. The goal of this study was to determine whether modulating ion channel activity alters membrane resistivity sufficiently to limit electrical conduction. Hamster cerebral arteries were isolated, cannulated and subjected to a conduction protocol. Focal KCl stimulation elicited a vasoconstriction that conducted robustly along the arterial wall. Manipulating voltage-dependent K+ (BKCa, Kv) channels did not produce significant changes in conduction decay; nor did modification of ATP-sensitive KATP channels. In contrast, Ba2+ blockade of inwardly rectifying (KIR) channels augmented conduction decay, an effect attributed to the loss of negative slope conductance. Conduction experiments performed for the first time on human cerebral arteries also demonstrated a robust conducted constrictor response. This study shows that selective smooth muscle K+ conductance can tune electrical communication if it retains appropriate biophysical properties.

Publisher: name: No Publisher Supplied
Year: 1979

description: The forage base for resident and migratory fish utilizing Little Egg Harbor Bay consists of at least one hundred and forty-two invertebrate and vertebrate taxa. Stomach content analyses conducted on 1,340 fish of 55 species provide estimates of the importance of each forage taxa to species and species-size group components of the fish populations. Over300 species or genus level predator-prey relationships are documented. Through comparison of fish survey data and stomach contents, the relative predation impact of each fish species on selected forage populations was determined for the study period.
