description: Chemical, biological, and stable isotope analyses were used simultaneously to track the spatial recovery of rivers from wastewater nutrient enrichment in the Bow and Red Deer Rivers of southern Alberta, Canada during the summers of 2002 and 2003. Exponential models assessed how far downstream it took the rivers to recover to pre­wastewater conditions. The Red Deer River recovered from nutrient enrichment~ 36, 29, and 70 km downstream according to nutrient concentrations, autotroph biomass and stable isotope values respectively. The Bow River recovered~ 192, 52 and 176 km downstream according to nutrient concentrations, autotroph biomass and stable isotope values. High spatial and temporal variability characterized many indicators. The integration of stable isotopes and autotroph biomass suggests that wastewater alters river food webs. Autotroph biomass and N isotopic composition provided the most time­integrated measure of conditions and generally displayed the most consistent recovery patterns with distance from the enrichment source.

description: Classical Hamiltonian system of a point moving on a sphere of fixed radius is shown to emerge from the constrained evolution of quantum spin. The constrained quantum evolution corresponds to an appropriate coarse-graining of the quantum states into equivalence classes, and forces the equivalence classes to evolve as single units representing the classical states. The coarse-grained quantum spin with the constrained evolution in the limit of the large spin becomes indistinguishable from the classical system.

description: Temperature-dependent, in-plane, thermoelectric power data are presented for single crystals of Ba(Fe1-xCox)2As2, 0\leqx\leq0.05, and Ba(Fe1-xRhx)2As2, (0\leqx\leq0.171). Given that previous thermoelectric power and angle resolved photoemission spectroscopy studies of Ba(Fe1-xCox)2As2 delineated a rather large Co-concentration range for Lifshitz transitions to occur, and the underdoped side of the phase diagram is poorly explored, new measurements of thermoelectric power on tightly spaced concentrations of Co, 0\leqx\leq0.05, were carried out. The data suggest evidence of a Lifshitz transition, but instead of a discontinuous jump in thermoelectric power between 0\leqx\leq0.05, a more gradual evolution in the S(T) plots as x is increased was observed. The thermoelectric power data of Ba(Fe1-xRhx)2As2 show very similar behavior to that of Co substituted BaFe2As2. The previously outlined T - x phase diagrams for both systems are further confirmed by these thermoelectric power data.

description: This thesis presents a simulation of auroral spectra, intensity values, and the genera­tion of realistic auroral images. Background information for auroral physics and ex­isting research is included. The simulation extends the methodology used in existing auroral simulation research by using dynamic subdivision to model the interactions in a spatial frame of reference, subdividing regions of high activity. The dynamic subdivision method is combined with a view independent mechanism for tracking the reactions to provide an efficient yet comprehensive analysis of auroral behavior. The advantage of the simulation presented in this thesis lies in its flexibility for modeling aurora based on scientifically-sound components and methods while allowing for the easy creation of realistic auroral images and animations suitable for use in the enter­tainment industry. The spectral results and simulation images are compared with existing data. In conclusion, potential extensions of these methods to other areas of auroral research are noted.

description: The energy loss of partons in high-energy nuclear collisions is one of the most interesting observables to probe the nature of the produced medium. Analyzing data from PbPb collisions at a center-of-mass energy of 2.76 TeV, recorded with the Compact Muon Solenoid (CMS) detector, parton energy loss is observed as a significant imbalance of dijet transverse momentum. To gain further understanding of the parton energy loss mechanism and how it manifests itself in the distribution of final state particles, fragmentation functions are studied for the leading and subleading jet in bins of dijet imbalance.

description: We analyze the fluctuations of the steady state profiles in the modulated phase of the ABC model. For a system of $L$ sites, the steady state profiles move on a microscopic time scale of order $L^3$. The variance of their displacement is computed in terms of the macroscopic steady state profiles by using fluctuating hydrodynamics and large deviations. Our analytical prediction for this variance is confirmed by the results of numerical simulations.

description: Every sufficiently big matrix with small spectral norm has a nearby low-rank matrix if the distance is measured in the maximum norm (Udell & Townsend, SIAM J Math Data Sci, 2019). We use the Hanson--Wright inequality to improve the estimate of the distance for matrices with incoherent column and row spaces. In numerical experiments with several classes of matrices we study how well the theoretical upper bound describes the approximation errors achieved with the method of alternating projections.

description: We study mean field dynamo action in renovating flows with finite and non zero correlation time ($τ$) in the presence of shear. Previous results obtained when shear was absent are generalized to the case with shear. The question of whether the mean magnetic field can grow in the presence of shear and non helical turbulence, as seen in numerical simulations, is examined. We show in a general manner that, if the motions are strictly non helical, then such mean field dynamo action is not possible. This result is not limited to low (fluid or magnetic) Reynolds numbers nor does it use any closure approximation; it only assumes that the flow renovates itself after each time interval $τ$. Specifying to a particular form of the renovating flow with helicity, we recover the standard dispersion relation of the $α^2 Ω$ dynamo, in the small $τ$ or large wavelength limit. Thus mean fields grow even in the presence of rapidly growing fluctuations, surprisingly, in a manner predicted by the standard quasilinear closure, even though such a closure is not strictly justified. Our work also suggests the possibility of obtaining mean field dynamo growth in the presence of helicity fluctuations, although having a coherent helicity will be more efficient.

No Correlation Between Disc Scale-Height and Jet Power in GRMHD Simulations

description: It is now well established that changes in the X-ray spectral state of black hole low-mass X-ray binaries are correlated with changes in the radio properties of those systems. Assuming radio power is a proxy for jet power, we can say that the jet is continuously present in the hard state and undetectable (and therefore weaker) in the soft state. Since the different accretion states are also generally assumed to be associated with different disc geometries -- the hard state with a hot, thick flow, and the soft state with a cold, thin disc -- we investigate the possibility that these two phenomena are linked; i.e., that the difference in disc geometry is the cause of the difference in observed jet power. We do this by comparing various measures of jet power in numerical simulations of accretion discs of differing temperatures and thicknesses. We perform these simulations using the general relativistic magnetohydrodynamic code Cosmos++ and a newly added cooling function, which allows us to regulate the disc scale height H/r at different radii. We find no apparent correlation between the disc scale height and jet power whenever we normalize the latter by the mass accretion history of each simulation. We attribute this result to the role that the "corona" plays in confining and accelerating the jet (our corona may also be considered a failed MHD "wind"). The properties of the corona do not vary significantly from one simulation to another, even though the scale heights of the discs vary by up to a factor of four. If this holds true in nature, then it suggests that the correlation between spectral state and jet power must be attributable to some other property, possibly the topology of the magnetic field. Alternatively, it could be that the corona disappears altogether in the soft state, which would be consistent with observations, but has so far not been seen in simulations.

Thermoregulation by big brown bats (eptesicus fuscus): ontogeny, proximate mechanisms, and dietary influences

description: Bibliography: p. 167-193
description: Some pages are in colour.
description: I studied the thermoregulatory behaviour of big brown bats (Eptesicus fuscus) of different ages in the field, investigated adaptations associated with thermoregulation (i.e., degree of insulation, clustering behaviour, hair development, and changes in metabolic rate), and examined potential dietary influences (i.e., fatty acid content of milk and handling-time of beetles) on the use of torpor. By extrapolating laboratory measurements of metabolic rate at given skin temperatures and ambient temperatures, I estimated metabolic savings associated with torpor in the field for bats based on skin temperature and ambient temperature measurements alone. On a daily basis, estimated energy expenditure of individual bats in the field was 5-19% lower than if they had remained normothermic over 24 h. Morphological, behavioural, and physiological factors may contribute to energy expenditure or energy savings from the use of torpor. For example, clustering within the roost further reduced expenditure. Laboratory measurements of skin temperature and metabolic rate indicated that clustering by older juveniles and adults reduced metabolic expenditure by up to 52%. Alternatively, by going torpid at low ambient temperatures, metabolic savings up to 98% were realized by bats during metabolic trials. Unlike older juveniles, early prevolant juveniles appear incapable of staying warm when their mothers are away from the roost during foraging. The body of E. fuscus was fully furred by 7 days of age, coinciding with fully developed thermoregulatory capability. Because early prevolant juveniles did not maintain normothermic body temperatures at low ambient temperatures when stimulated to do so, it appears as though they are physiologically incapable of staying warm, rather than being capable of staying warm but choosing not to. Early prevolant juveniles may not realize any energetic benefits associated with clustering, and it may be more beneficial for them to roost alone. Changes in milk composition during lactation corresponded to changes in thermoregulatory ability of juvenile E. fuscus. Handling time of beetles by volant juveniles was significantly different from that of adults, corresponding with a reduction in the use of torpor by early volant juveniles. These data suggest that diet may play a significant role in limiting use of torpor.

Modeling inertial sensors errors using Allan variance
Creators: name: Hou, Haiying
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 123-128
description: It is well known that Inertial Navigation Systems (INS) can provide high accuracy information on the position, velocity, and attitude over a short time period. However, their accuracy degrades rapidly with time. The requirements for accurate estimation of navigation information necessitate the modeling of the sensors' noise components. Several methods have been devised for stochastic modeling of inertial sensors noise. Each of them is useful but each has its own disadvantage. The Adaptive Kalman filter is one of the mostly used methods to estimate inertial sensor noise, but the form of the model needs to be known first. Frequency domain approaching uses the power spectral density to estimate transfer functions. It is straightforward but it is difficult for non­system analysts to understand. In the time domain methods, the correlation function approach is very model sensitive. Variance techniques are basically very similar, and primarily differ only in that various signal processing, by way of weighting functions, window functions, etc., are incorporated into the analysis algorithms in order to achieve a particular desired result for improving the model characterizations. The simplest technique is the Allan variance method. Allan variance is a method of representing root mean square (RMS) random drift error as a function of average time. It is simple to compute and relatively simple to interpret and understand. Allan variance method can be used to determine the character of the underlying random processes that give rise to the data noise. This technique can be used to characterize various types of noise terms in the inertial sensor data by performing certain operations on the entire length of data. In this thesis, the Allan variance technique is used in noise analysis of different grade Inertial Measurement Units (IMU), which include: • Navigation grade IMU: The Honeywell Commercial IMU (CIMU); • Tactical grade IMU: The Honeywell HG 1700; and ■ Consumer grade MEMS based IMU: The Systron Donner MotionPak II-3g By performing a simple operation on the entire length of data, a characteristic curve is obtained whose inspection provides a systematic characterization of various random errors contained in the inertial sensor output data. Being a directly measurable quantity, Allan variance can provide information on the types and magnitude of various noise terms. The research work will cover both the theoretical basis for Allan Variance for modeling inertial sensors noise terms, and its implementation in modeling different noise terms existing in the different grade inertial sensors. Simple implementation and ease of interpretation make the Allan variance method suitable in inertial sensor noise identification and stochastic modeling.
Control of hydrogen sulfide production in oil fields by managing microbial communities through nitrate or nitrite addition
Creators: name: Hubert, Casey R.J.
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 165-175
description: Nitrate or nitrite injection into oil reservoirs during water flooding has the potential to control biological souring, the production of hydrogen sulfide (H2S) by sulfate-reducing bacteria (SRB). Souring control is essential because sulfide is toxic, sulfide precipitates can plug reservoir formations, souring lowers crude oil value, and SRB induce corrosion. Nitrate and nitrite can stimulate heterotrophic nitrate- or nitrite­reducing bacteria (hNRB) and nitrate- or nitrite-reducing, sulfide oxidizing bacteria (NR­SOB). Nitrite also inhibits SRB activity by blocking the sulfate reduction pathway. Continuous up-flow packed-bed bioreactors were inoculated with produced water from the Coleville oil field to establish sulfide-producing biofilms similar to those found in sour reservoirs. Nitrate or nitrite addition to bioreactors indicated that the dose required for hNRB or NR-SOB to control souring depended on the concentration of oil organics. Either mechanism mediates the net removal of oil organics (lactate) with nitrate or nitrite, with lower doses of nitrate required due to its greater oxidative power. Microbial community analysis by reverse sample genome probing (RSGP) revealed that NR-SOB mediated sulfide removal at low nitrate or nitrite concentrations when lactate was still available to SRB and the redox potential was low. At high nitrate doses hNRB oxidized lactate directly, produced nitrite and maintained a high redox potential, thus excluding SRB activity. Facultatively chemolithotrophic Campylobacter sp. strains were isolated from the bioreactors and incorporated into RSGP analyses, revealing their dominance in both NR-SOB- and hNRB-containing communities. The metabolic flexibility of these strains may confer a competitive advantage over obligate chemolithotrophs like Thiomicrospira sp. strain CVO or hNRB that do not have NR-SOB activity like newly isolated Thauera sp. and Rhodobacter sp. strains. A single high dose of nitrite resulted in immediate inhibition of SRB that was independent of hNRB or NR-SOB. Examination of corrosion coupons following bioreactor experiments revealed that nitrite inhibition was the only mechanism that prevented both souring and corrosion. Sulfide elimination by hNRB or NR-SOB resulted in increased pitting corrosion in the region of greatest microbial activity. These findings are instructive for designing souring control treatments and improve understanding of oil field microbial communities.

description: This work introduces a novel blackbox optimization algorithm for computationally expensive constrained multi-fidelity problems. When applying a direct search method to such problems, the scarcity of feasible points may lead to numerous costly evaluations spent on infeasible points. Our proposed fidelity and interruption controlled optimization algorithm addresses this issue by leveraging multi-fidelity information, allowing for premature interruption of an evaluation when a point is estimated to be infeasible. These estimations are controlled by a biadjacency matrix, for which we propose a construction. The proposed method acts as an intermediary component bridging any non multi-fidelity direct search solver and a multi-fidelity blackbox problem, giving the user freedom of choice for the solver. A series of computational tests are conducted to validate the approach. The results show a significant improvement in solution quality when an initial feasible starting point is provided. When this condition is not met, the outcomes are contingent upon specific properties of the blackbox.

description: We have developed a method for detecting clusters in large imaging surveys, based on the detection of structures in galaxy density maps made in slices of photometric redshifts. This method was first applied to the Canada France Hawaii Telescope Legacy Survey (CFHTLS) Deep 1 field by Mazure et al. (2007), then to all the Deep and Wide CFHTLS fields available in the T0004 data release by Adami et al. (2010). The validity of the cluster detection rate was estimated by applying the same procedure to galaxies from the Millennium simulation. Here we analyse with the same method the full CFHTLS Wide survey, based on the T0006 data release. In a total area of 154 deg2, we have detected 4061 candidate clusters at 3sigma or above (6802 at 2sigma and above), in the redshift range 0.1<=z<=1.15, with estimated mean masses between 1.3 10^14 and 12.6 10^14 M_solar. This catalogue of candidate clusters will be available online via VizieR. We compare our detections with those made in various CFHTLS analyses with other methods. By stacking a subsample of clusters, we show that this subsample has typical cluster characteristics (colour-magnitude relation, galaxy luminosity function). We also confirm that the cluster-cluster correlation function is comparable to that obtained for other cluster surveys and analyze large scale filamentary galaxy distributions. We have increased the number of known optical high redshift cluster candidates by a large factor, an important step towards obtaining reliable cluster counts to measure cosmological parameters. The clusters that we detect behave as expected for a sample of clusters fed by filaments at the intersection of which they are located.

GaAs nanomembranes with an area of 1.36 mm by 1.91 mm and a thickness of 160 nm are obtained by using a two-step selective wet-etching technique. The frequency noise spectrum reveals several mechanical modes in the kilohertz regime with mechanical Q-factors up to 2,300,000 at room temperature. The measured mechanical mode profiles agree well with a taut rectangular drumhead model. Our results show that GaAs nanomembranes provide a promising path towards quantum optical control of massive nanomechanical systems.

description: Social media has become one of the primary modes of communication in recent times, with popular platforms such as Facebook, Twitter, and Instagram leading the way. Despite its popularity, Instagram has not received as much attention in academic research compared to Facebook and Twitter, and its significant role in contemporary society is often overlooked. Web archives are making efforts to preserve social media content despite the challenges posed by the dynamic nature of these sites. The goal of our research is to facilitate the easy discovery of archived copies, or mementos, of all posts belonging to a specific Instagram account in web archives. We proposed two approaches to support account-based queries for archived Instagram posts. The first approach uses existing technologies in the Internet Archive by using WARC revisit records to incorporate Instagram usernames into the WARC-Target-URI field in the WARC file header. The second approach involves building an external index that maps Instagram user accounts to their posts. The user can query this index to retrieve all post URLs for a particular user, which they can then use to query web archives for each individual post. The implementation of both approaches was demonstrated, and their advantages and disadvantages were discussed. This research will enable web archivists to make informed decisions on which approach to adopt based on practicality and unique requirements for their archives.

description: Molecular dynamics simulations (mds) were carried out to investigate the reorientational motion of a rigid (fixed bond length), asymmetric diatomic molecule in the liquid and glassy states. In the latter the molecule reorients via large-angle jumps, which we identify with the Johari-Goldstein (JG) dynamics. This relaxation process has a broad distribution of relaxation times, and at least deeply in the glass state, the mobility of a given molecule remains fixed over time; that is, there is no dynamic exchange among molecules. Interestingly, the JG relaxation time for a molecule does not depend on the local density, although the non-ergodicity factor is weakly correlated with the packing efficiency of neighboring molecules. In the liquid state the frequency of the JG process increases significantly, eventually subsuming the slower alpha-relaxation. This evolution of the JG-motion into structural relaxation underlies the correlation of many properties of the JG- and alpha-dynamics.

description: In this thesis, two related streams of research are presented: the empirical evaluation stream and the organizational readiness stream. In the empirical evaluation steam, we describe the results of an experiment comparing traditional test-last development to test-driven development. Test-driven development is an approach for designing software that involves using tests to guide the design effort. In the organizational readiness stream of the research we report on the results of a regional survey of software testing practices and present the contents of a brief analysis of risks facing those organizations that are in the process of adopting test-driven development. The common thread between the two streams is software testing, specifically characterizing the testing-related skills that both developers and organizations require in order to continue to compete in the global software market. We conclude that there is a need for increased testing knowledge and ability; especially at the system and acceptance test levels. This increased knowledge would also decrease the risk the organization faces when migrating from a traditional test-last development process to a test­driven development process.

description: Using a panel of Australian data and OLS regression, I estimate a 28.5 percent level of demand for private health insurance in Alberta and present a theoretical model of utility analysis to describe the requisite conditions for a successful private health market. My analysis indicates the demand for private health insurance in Alberta would be price and income inelastic; limiting government's ability to affect health insurance purchase decisions. Moreover, a quality gap would have to exist between private and public health goods for a private health market to be successful. The modeled annual private health insurance premium of $826, applicable to the 28.5 percent demand estimate, would not cover costs, requiring significant government subsidization. My conclusion is caution must be exercised before any steps are made towards a private health care market in Alberta as demand may not be sufficient to support a self-financing private health market.

description: In this paper, we delve into the challenge of optimizing joint communication and computation for semantic communication over wireless networks using a probability graph framework. In the considered model, the base station (BS) extracts the small-sized compressed semantic information through removing redundant messages based on the stored knowledge base. Specifically, the knowledge base is encapsulated in a probability graph that encapsulates statistical relations. At the user side, the compressed information is accurately deduced using the same probability graph employed by the BS. While this approach introduces an additional computational overhead for semantic information extraction, it significantly curtails communication resource consumption by transmitting concise data. We derive both communication and computation cost models based on the inference process of the probability graph. Building upon these models, we introduce a joint communication and computation resource allocation problem aimed at minimizing the overall energy consumption of the network, while accounting for latency, power, and semantic constraints. To address this problem, we obtain a closed-form solution for transmission power under a fixed semantic compression ratio. Subsequently, we propose an efficient linear search-based algorithm to attain the optimal solution for the considered problem with low computational complexity. Simulation results underscore the effectiveness of our proposed system, showcasing notable improvements compared to conventional non-semantic schemes.

description: The pilgrimages of Muslims to Makkah (Hajj and Umrah) is one of the largest religious gatherings in the world which draws millions of people from around 180 countries each year. Heat stress during summer has led to health impacts including morbidity and mortality in the past, which is likely to worsen due to global warming. Here we investigate the impacts of increasing heat stress during the peak summer months over Makkah at present levels of warming as well as under Paris Agreement's targets of 1.5 °C and 2 °C global mean temperature increase above pre-industrial levels. This is achieved by using multi member ensemble projections from the half a degree additional warming, prognosis and projected impacts project. We find a substantial increase in the exceedance probabilities of dangerous thresholds (wet-bulb temperature >24.6 °C) in 1.5 °C and 2 °C warmer worlds over the summer months. For the 3 hottest months, August, September and October, even thresholds of extremely dangerous (wet-bulb temperature >29.1 °C) health risks may be surpassed. An increase in exceedance probability of dangerous threshold is projected by two and three times in 1.5 °C and 2 °C warmer worlds respectively for May as compared to the reference climate. September shows the highest increase in the exceedance probability of extremely dangerous threshold which is increased to 4 and 13 times in 1.5 °C and 2 °C warmer worlds respectively. Based on the indicators of hazard, exposure and vulnerability, we carried out probabilistic risk analysis of life-threatening heat stroke over Makkah. A ten time increase in the heat stroke risk at higher wet-bulb temperatures for each month is projected in 2 °C warmer world. If warming was limited to 1.5 °C world, the risk would only increase by about five times, or half the risk of 2 °C. Our results indicate that substantial heat related risks during Hajj and Umrah happening over peak summer months, as it is the case for Hajj during this decade, will require substantial adaptation measures and would negatively affect the performance of the rite. Stringent mitigation actions to keep the global temperature to 1.5 °C can reduce the risks of heat related illnesses and thereby reduce the non-economic loss and damage related to one of the central pillars of a world religion.
A conservation law formulation of nonlinear elasticity in general relativity

description: We present a practical framework for ideal hyperelasticity in numerical relativity. For this purpose, we recast the formalism of Carter and Quintana as a set of Eulerian conservation laws in an arbitrary 3+1 split of spacetime. The resulting equations are presented as an extension of the standard Valencia formalism for a perfect fluid, with additional terms in the stress-energy tensor, plus a set of kinematic conservation laws that evolve a configuration gradient. We prove that the equations can be made symmetric hyperbolic by suitable constraint additions, at least in a neighbourhood of the unsheared state. We discuss the Newtonian limit of our formalism and its relation to a second formalism also used in Newtonian elasticity. We validate our framework by numerically solving a set of Riemann problems in Minkowski spacetime, as well as Newtonian ones from the literature.

description: History of transportation dates back to the medieval period through the use of domestic animals which are used in transporting heavier loads or humans riding animals for easy conveyance and speed. The industrial revolution in the nineteenth century saw various inventions which changed the phase and means of transportation such as telegraphy. Means of communication became a necessity and independent of the transport of physical objects. Road transport is an essential part of the transport system and the most common form of transport. Road transport is vital to the economic development and social integration of the country. However this sector has face different problems, therefore the study investigates the effect of driver’s performance on road transport operation with reference to Unique Transport Cross Border Freight Association, Addis Ababa, Ethiopia. The objective of the study was to investigate drivers behavior, skill, health, and fatigue influence on road transport operation in unique transport cross borders. A survey was conducted by drawing sample size of 126 from a target population of 175 by using simple random sampling. The researcher used structured questionnaires to collect data. The relationships proposed in the framework were tested using Pearson correlation, and the causal relations were analyzed using regression analysis. And the research has found drivers behavior, driver’s skill, driver’s health and drivers fatigue has a positive and significant influence on road transport operation

"I am Joseph, your brother": use of the brother model in the Vatican's conception of the Jewish-Catholic relationship, 1958-2004
Creators: name: Gibbard, Nathan
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 126-137
description: This thesis seeks to explore the Vatican's use of the "brother" metaphorical model in its understanding of the relationship between Jews and Catholics. After providing a brief historical background, the thesis examines how the "brother" model of Jewish-Catholic relationships has developed since the time of John XXIII. From John XXIll's simple statement of reconciliation, "I am Joseph, your brother," a change in the metaphorical relationship can be seen. Tracing the development of the brother model through John XXIII' s reign up until the present, the thesis will examine how Vatican language in papal and curial documents has changed and adjusted over time, expressing different understandings of the relationship between Catholics and Jews.

description: Although use of the Internet for purposes of delivering mental health services has exploded in recent years, there remains a tremendous gap in our knowledge about the nature of these online services. This thesis examines the characteristics of 53 current social work and psychologist online mental health sites located in Canada and the United States of America. The research was based on a content analysis of English speaking sites that offer clinical service to the general public. To be included in the study web sites had to offer a medium of clinical intervention, such as e-mail, chat or video conferencing, over the Internet. The results were evaluated against the backdrop of professional practice standards off-line and online with reference to the National Board of Certified Counselors and the International Society for Mental Health Online. In general, results indicated that online practitioners compliance with current online standards was poor.
