Trujillo, Leonardo. "Benchmarking methods for repeated business surveys." Thesis, University of Southampton, 2007. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.486432.
Full textAbstract:
Benchmarking corresponds to a combination of two sources of information on a given variable. In many situations, the problem consists of combining a series of frequent data with a series of less frequent but more accurate data for producing more accurate estimates of the former series. For example, estimates of population characteristics are derived from the last census and researchers re-estimate the values for the time gap between two censuses using more regular information. In what follows we focus in the .' problem of benchmarking monthly data with annual estimates; then, the benchmarking consists of forcing the sum of the monthly signals to equal the signal of the benchmark. Alternative estimators have been proposed in the literature for benchmarking. When the adjusted series agrees exactly with these benchmarks, the benchmarking is called binding. The binding process is implemented by setting the variance of. the annual survey errors to zero. However, it is necessary to account for the variance of the annual survey errors when computing the variances of the benchmarked estimators. In this thesis, we develop the theoretical expression of the correct variance as well as an expression for the excess in the variance due to the binding process. The results are extended to the most known bepchmarking methods proposed in the literature. An application to business surveys used for official statistics in the UK is presented, illustrating some particular issues regarding the state space modelling. Finally, the problem of how to prepare tabular data classified by attributes as columns and points in time as rows is analyzed. This multivariate extension of the benchmarking problem distinguishes two basic type of problems: when only marginal totals are available (contemporaneous disaggregation) and when the aggregates do not correspond with the sum of the disaggregated values by year and/or by attributes (reconciliation). The scope of this thesis is based basically in a state space model approach.

DeSanto, John B. "Measuring Seafloor Displacement Using Repeated Sidescan Sonar Surveys." Thesis, University of California, San Diego, 2019. http://pqdtopen.proquest.com/#viewpdf?dispub=10978975.
Full textAbstract:
The purpose of this thesis is to propose and develop a novel tool for measuring seafloor displacement using repeated sidescan sonar surveys, a data set that is collected alongside multibeam bathymetry. Chapter 1 presents the motivation for this study and introduces the work done in subsequent chapters. Chapter 2 is a brief overview of the design and underlying physics of the multibeam sonar, and presents a discussion on the uncertainties introduced by errors in the sound velocity profile. Chapter 3 presents the processing method for measuring seafloor displacement from sidescan sonar in detail, and tests this method by measuring synthetic displacements introduced into legacy multibeam data. Chapter 4 presents data collected in calibration surveys during the RR1605 and SR1704 cruises meant to test this method. We find displacements measurements with RMS uncertainties less than 0.5 m under optimal survey designs involving speeds less than 6 knots, kinematic post-processed ship navigation, and frequent measurements of the sound velocity profile. Chapter 5 demonstrates the improvement in ship positioning obtained when performing kinematic post-processing on the raw ship navigation data rather than relying on the real-time navigation solution.

With the growing popularity of business analytics, companies experience an increasing need of reliable data. Although the availability of behavioural data showing what the consumers do has increased, the access to data showing consumer mentality, what the con- sumers actually think, remain heavily dependent on tracking surveys. This thesis inves- tigates the performance of a Dynamic Factor Model using respondent-level data gathered through repeated cross-sectional surveys. Through Monte Carlo simulations, the model was shown to improve the accuracy of brand tracking estimates by double digit percent- ages, or equivalently reducing the required amount of data by more than a factor 2, while maintaining the same level of accuracy. Furthermore, the study showed clear indications that even greater performance benefits are possible.

Perkins, Drew Allen. "Evaluating Geomorphic Change in Little Creek Using Repeated Cross-Sectional and Longitudinal Profile Surveys." DigitalCommons@CalPoly, 2012. https://digitalcommons.calpoly.edu/theses/711.
Full textAbstract:
Six geomorphic study reaches were established in 2002 along a forested mountain stream (gradients range from 0.02 to 0.05) on Cal Poly's Swanton Pacific Ranch in Santa Cruz County, California. These study reaches are a component of paired and nested watershed studies in the approximately 500 hectare Little Creek watershed. The overall goal of this study was to monitor water quality and channel conditions before, during, and after a selective harvest of redwood. A selective harvest occurred in the North Fork of Little Creek in Summer 2008. In August 2009, approximately 90% of the Little Creek Watershed was burned in the Lockheed Fire. Channel change was evaluated by measuring ground profiles using traditional survey methods. Cross section and longitudinal profiles are surveyed annually every summer in the six study reaches. Change is assessed through evaluation of cross sections and longitudinal profiles, analysis of bed elevation and cross-sectional area change data, and analysis of residual pool characteristics and longitudinal profile variability. Changes in the channel during this time have been relatively small and are typically associated with movement or introduction of coarse woody debris to the stream channel. However, during the study period no large stream flow events occurred (return interval at the closest USGS gauging station does not exceed 5 years). Historically, large debris flow events have occurred in this watershed, with well documented events in 1955 and 1998. The survey data is an important tool for understanding change detection in channel characteristics before and after harvesting, and following fire disturbance.

Four surveys of users of the AskERIC email reference service were conducted, during the years 1998, 2000, 2001, and 2002. These surveys presented a snapshot of the AskERIC user population and user satisfaction at a single point in time. This paper reanalyzes the findings from these surveys utilizing repeated survey techniques. This paper presents the evolution of some of the demographics of AskERICâ s user population over time, as well as the evolution of AskERIC user behavior. As perhaps the oldest AskA service in existence, this analysis of AskERIC data sheds light on the evolution of all AskA services, and of email-based reference services in general.

Full textAbstract:
Imputation is commonly used for missing data in sample surveys. Usually the imputed values are treated as true values and variance estimates are computed using standard variance formulas. But this procedure can lead to serious underestimation of the true variance. Rao and Shao (1992) proposed a new consistent jackknife variance estimator based on adjusting the imputed values. This thesis applies their idea to construct two adjusted Balanced Repeated Replication (BRR) variance estimators for stratified multistage surveys. Under a uniform response mechanism, the adjusted BRR variance estimators are shown to be consistent for a particular simple hot deck imputation and ratio hot deck imputation. Also, the relationship between jackknife variance estimators and BRR variance estimators which was established by Rao and Wu (1985) for completed data set, is shown to be still held for data set with imputed values. The performances of these variance estimates are compared through some simulation studies.

Matsuda, Yui. "The relationship between repeat unintended pregnancies and current family planning practice." VCU Scholars Compass, 2009. http://scholarscompass.vcu.edu/etd/2031.
Full textAbstract:
Nearly half of all pregnancies in the United States are unintended. In 2002, the direct medical costs of unintended pregnancies were estimated to be almost five billion dollars. Moreover, women with unintended pregnancies tend to delay seeking prenatal care and making the necessary life style changes for the fetus. Subsequently, unintended pregnancies have the potential to lead to low birth weight infants and potentially poorer long-term child development. Although there are negative consequences with unintended pregnancies, repeat unintended pregnancies impose even greater health risks for both mothers and infants. To prevent unintended and repeat unintended pregnancies, family planning methods must be utilized effectively. Despite the potential risk associated with negative health outcomes of mothers and infants, repeated unintended pregnancies have not been studied extensively. Therefore, the purpose of this study was to examine the relationship between the number of unintended pregnancies and effective use of family planning methods. A secondary analysis of The National Statistics of Family Growth, cycle 6 (2002) was done. The study showed a statistically significant relationship association between the number of unintended pregnancies and effective contraceptive use after adjusting for confounders which include age, race, annual household income, marital status and types of insurance. The recommendation of this study include creating better strategies for family planning practices and the need to improving contraceptive education and service delivery for those with higher risk.

Full textAbstract:
Transposable elements (TEs) are mobile genetic elements capable of replicating and
spreading within, and in some cases, between genomes. I describe a whole-genome
analysis of DD34E TEs, which belong to the IS630-Tc1-mariner superfamily of DNA
transposable elements, in the African malaria mosquito, Anopheles gambiae. Twenty-six
new transposons as well as a new family, gambol, were identified. The gambol family
shares the DD34E catalytic motif with Tc1-DD34E transposons, but is distinct from these
elements in their phylogenetic relationships. Although gambol appears to be related to a
few DD34E transposons from cyanobacteria and fungi, no gambol elements have been
reported in any other insects or animals thus far. This discovery expands the already
expansive diversity of the IS630-Tc1-mariner TEs, and raises interesting questions as to
the origin of gambol elements and their apparent diversity in An. gambiae. Several
DD34E transposons discovered in An. gambiae possess characteristics that are associated
with recent transposition, such as high sequence identity between copies, and intact
terminal-inverted repeats and open reading frames. One such element, AgTango, was also
found in a distantly related mosquito species, Aedes aegypti, at high amino acid sequence
identity (79.9%). It was discovered that Tango transposons have patchy distribution
among twelve mosquito species surveyed using PCR as well as genomic searches,
suggesting a possible case for horizontal transfer. Additionally, it was discovered that in
some mosquito genomes, there are several Tango transposons. These observations
suggest differential evolutionary scenarios and/or TE-host interaction of Tango elements
between mosquito species. This strengthened the case that AgTango may be a functional
transposase, and I sought to test its potential activity in a cell culture-based inter-plasmid
transposition assay using the Herves plasmids as a positive control (Arensburger et al.,
2005). AgTango constructs were successfully constructed; however, no transposition
events were detected for Tango or Herves. Because the positive control failed to work, no
assessment can be made concerning Tango's transposase. Possible causes and solutions
for these results, alternative means to detect transposition, as well as future directions
with Tango are discussed.Ph. D.

Wiberg, Dustin S. "Development of a Survey Measuring Visitor Satisfaction and Service Quality of Cultural and Natural Sites in Belize." DigitalCommons@USU, 2009. https://digitalcommons.usu.edu/etd/294.
Full textAbstract:
The literature suggests that a correlation exists between visitor satisfaction and a visitor's choice to re-experience a product. The higher one's satisfaction level, the more likely he/she is to experience the product again and/or provide positive word-of-mouth advertising to friends and family. The Tian-Cole and Crompton model was chosen because of its acknowledgment and explanation of the differences between Visitor Satisfaction (VS) and Service Quality (SQ) and how their relationship influences satisfaction and contributes to Future Destination Selection.
In addition to identifying a theoretical framework that explains why visitors return, it was necessary to identify a survey methodology to be used in developing the Mountain Pine Ridge Forest Reserve (MPRFR) visitor satisfaction surveys. It was determined that a combination of the Relative Performance Assessment (RPA) and Customer Service Questionnaire (CSQ) was an appropriate survey framework for a visitor satisfaction survey.
As a result of the research, two visitor satisfaction surveys were developed: Intercept Survey and Mail-back Survey. The Intercept Survey will be administered at a MPRFR site. It was designed to be concise and not take much of the visitor's time. This survey will be used to gather general information about visitor characteristics and level of satisfaction while at a site. The Mail-back Survey will be sent to the visitor after their trip so more time can be devoted to answering a more detailed visitor satisfaction survey. This survey asks visitors to indicate what site characteristics are important to them and then rate their satisfaction with each item. Instruments from the report entitled "A Front Country Visitor Study for Grand Staircase-Escalante National Monument" were used as an example of how to format a visitor satisfaction survey and how to use the collected data as a managerial tool.
The two main objectives of this research were accomplished and have established a foundation upon which subsequent research efforts will begin. This work serves as a catalyst to improving Belizean site planning, design, and management by better understanding what site characteristics contribute to visitor satisfaction.

Full textAbstract:
Landtagswahlergebnisse in der BRD werden von empirischen Wahlforschern häufig als aktuelle Stimmungsbarometer für die Bundespolitik interpretiert. Bei dieser Interpretation von Landtagswahlen als \"Bundestestwahlen\" wird jedoch häufig vernachlässigt, dass Landtagswahlen überwiegend auch Regionalwahlen sind und landestypischen Dynamiken folgen. Empirische Untersuchungen zu Bestimmungsfaktoren von Landtagswahlverhalten wurden in Deutschland bis dato entweder in Form von qualitativen Einzelfallanalysen oder als Aggregatdatenanalysen der amtlichen Wahlstatistiken durchgeführt. Eine direkte und vergleichende Quantifizierung der Effektstärken mit Survey-Daten wurde allerdings bislang nicht vorgenommen. Die vorliegende Studie wertet deshalb im Rahmen eines replikativen Surveys 17 Landtagswahlstudien aus. So können die Effektstärken der individuellen Bewertung der Bundes- versus der Landesparteien auf die Landtagswahlentscheidungen direkt verglichen werden. Als Fazit zeigt sich, dass in Westdeutschland die Beurteilung der Landesparteien einen stärkeren Einfluss auf die individuelle Landtagswahlentscheidung ausübt als die Beurteilung der Bundesparteien. In Ostdeutschland prägt dagegen bei Landtagswahlen die bundespolitische Dimension das Abstimmungsverhalten der Wähler stärker. Die Parteipolitikverflechtung zwischen Landes- und Bundesebene ist somit bei Landtagswahlen in Ostdeutschland erheblich stärker ausgeprägt als in den alten BundesländernElectoral studies often interpret German regional election results ("Landtagswahlen") as barometers of public opinion on federal governmental parties' performance. However, while interpreting German regional elections as "test-elections" for the national parliament, it is often underemphasised that subnational elections often follow a unique regional dynamics. So far, empirical investigations on the determinants of German regional elections consist either in qualitative case studies or aggregate analyses of official statistics. A quantitative study of individual-level survey data, comparing directly the explanatory power of the federal versus the subnational level, is still lacking. Conducting a repeated survey design, we analyse data from 17 German regional election surveys. Thus, the effects of individual assessments of federal parties versus their subnational counterparts on subnational voting preferences can be directly compared. The conclusion of our analyses can be summarized as follows: In Western Germany, the valuation of subnational parties has a stronger impact on individual voting preferences in subnational elections than the valuation of the federal parties has. However, in Eastern Germany, the federal dimension has a comparatively stronger effect. Hence, the federal – regional ("Länder") party system linkage is clearly stronger in Eastern than in Western Germany

Full textAbstract:
Considerable progress has been made in the past two decades on research into survey sampling methodologies. A significant trend
in this development is that the classical survey sampling techniques are formulated using an inference framework, which is
made possible by assuming that the given finite population is a realization of a superpopulation model with unknown parameters. One attraction of this method of formulation of survey sampling problems is that not only the classical tools of inference can usefully be brought to bear on the problem, but more importantly, the optimal properties of certain familiar estimators in classical survey sampling are more and more better understood.
A central issue in the use of superpopulation models for designing sampling strategies is robustness of the procedures. Under the design-based approach, it is claimed in the literature that robustness is provided by requiring that the estimators are design-unbiased, a property which is independent of the assumed
superpopulation model. Chapter 1 examines the claim in detail and provide sufficient conditions for the sampling strategy to attain the Godambe-Joshi lower bound to the expected variance (Godambe & Joshi , 1965) .
Chapter 2 and Chapter 3 examine the issues of
reconciling design-based estimators with model-based predictors. The approach adopted in Chapter 2 is to retain the asymptotic
design unbiasedness of the predictors, but modify the form of the estimators for the superpopulation model parameters in constructing the predictors of.population totals. On the other hand, the approach adopted in Chapter 3 is to retain the model based properties of the predictors but modify the selection probailites for selecting the sample. The discussion for Chapters 1 to 3 is restricted to the design and analysis of ad hoc surveys, that is, surveys which are conducted once on a given finite population. Chapter 4 and Chapter
5 examine issues related to the analysis of repeated surveys of the finite population over time. Chapter 6 looks at specification of superpopulation models for
survey sampling from the point of view of performing regression analysis on the survey data from ad hoc surveys. It is argued that
under certain circumstances, the uniform intra-class correlation assumed in the covariance matrix of the superpopulation model is unnecessary.

Submitted to the faculty of the School of
Informatics in partial fulfillment of the requirements for the degree Master of Science in Bioinformatics in the School of Informatics,Indiana University July, 2004DNA markers have revolutionized the field of genetics by increasing the pace of genetic analysis. Simple sequence repeats (SSRs) are repetitions of nucleotide motifs of 1 to 5 bases and are currently the markers of choice in many plant and animal genomes due to their abundant distribution in the genomes, hypervariable nature and suitability for high-throughput analysis. While SSRs, once developed, are extremely valuable, their development is time consuming, laborious and expensive. Sequences from many genomes are continuously made freely available in the public databases and mining of these sources using computational approaches permits rapid and economical marker development. Expressed sequence tags (ESTs) are ideal candidates for mining SSRs not only because of their availability in large numbers but also due to the fact that they represent expressed genes. Large scale SSR mining efforts in plants to date focused on monocotyledonous plants. In this project, an efficient SSR identification tool was developed and used to mine SSRs from more than 53 dicotyledonous species. A total of 92,648 non-redundant ESTs or 6.0% of the 1.54 million dicotyledonous ESTs investigated in this study were found to contain SSRs. The frequency of non-redundant-ESTs containing SSRs among the species investigated ranged from 2.65% to 16.82%. More than 80% of the non-redundant ESTs having SSRs contained a single SSR repeat while others contained 2 or more SSRs. An extensive analysis of the occurrence and frequencies of various SSR types revealed that the A/T mononucleotide, AG/GA/CT/TC dinucleotide, AAG/AGA/GAA/CTT/TTC/TCT trinucleotide and TTTA and TTAA tetranucleotide repeats are the most abundant in dicotyledonous species. In addition, an analysis of the number of repeats across species revealed that majority of the mononucleotide SSRs contained 15-25 repeats while majority of the di- and tri-nucleotide SSRs contained 5-10 repeats. By providing valuable information on the abundance of SSRs in ESTs of a large number of dicotyledonous species, this study demonstrates the potential of computational mining approach for rapid discovery of SSRs towards the development of markers for genetic analysis and related applications.

Full textAbstract:
The Uncompahgre River in Ouray, CO, was modified in 1996 from a braided river system to a meandering river channel. Large boulders of riprap were placed along designed meanders to prevent erosion and enable the development of permanent human structures on the flood plain. Deposition of gravel bars in the modified channel occurs annually during the summer. This gravel is "mined" by the City of Ouray; however, the effects of this excavation and the original modification were never assessed.
This study provides an assessment by quantifying cross-sectional area change, cumulative grain-size distributions, shear stresses, slopes, and sinuosities using traditional survey methods. In addition, volume change of a gravel bar inside the modified channel was estimated using extreme oblique photographs (>45 degrees from nadir) that were obtained from nearby cliffs. Close-range photogrammetry was used in the natural channel downstream to evaluate photogrammetric methods using different lenses, image sensors, and camera geometries.
Both traditional and photogrammetric methods clearly indicated significant deposition in the modified channel, whereas erosion occurred directly downstream from the modified channel, but did not occur at a reach 1.5 km downstream. In the natural channel, no cross-sectional area change occurred, grains were poorly sorted, and the longitudinal slope was ~four times steeper than the modified channel. Shear stress ratios were used as an erosion threshold, which did not correlate with actual cross-sectional area change, but a decrease in shear stress ratios from May 2011 to September 2011 were associated with erosion. Average RMSE values for DEMs created from extremeoblique photographs of a gravel bar in May 2011 and September 2011 were 0.140 m and 0.324 m, respectively. Using a DEM of difference with a t-statistic filter revealed that 115m3 of gravel was deposited.
The Uncompahgre River showed similar geomorphic characteristics to other rivers in southwest Colorado, however, the slope of the natural and modified channels were much steeper than other rivers. Extreme-oblique photography and unconventional sensors both yielded reliable results, showing that these atypical techniques can be used in terrestrial photogrammetric applications such as, post-restoration assessments, as long as proper base-to-height ratios are achieved.

Dadswell, Kara. "Predicting risk of repeat firelighting in young people: the development and evaluation of the Behaviour Risk Tool." Thesis, 2018. https://vuir.vu.edu.au/38642/.
Full textAbstract:
Firelighting is not an uncommon behaviour for young people. A review of the
relevant literature shows that, fortunately, most young people who light fires, do so
because they are curious, and fire safety education intervention is enough to prevent any
future firelighting activity. However, a small number have significant psychosocial issues
that may contribute to continued firelighting behaviour.
The Juvenile Fire Awareness and Intervention Program (JFAIP) is a fire safety
education program established in Victoria, Australia to target active young firelighters.
While some young firelighters referred to the program have mental health problems, the
JFAIP is not designed for such cases. Thus a need has been identified for a screening
questionnaire to identify young people with psychosocial disturbance predictive of
ongoing firelighting behaviour, in order to recommend supplementary mental health
intervention. The overarching aim of this project was to develop such a screening tool.
The first aim of Study 1 was to evaluate the validity of two internationally
established firelighter screening tools, the FEMA Child Risk Survey (CRS) and Family
Risk Survey (FRS). The second aim was to explore the fire-specific, family and
psychosocial profile of young repeat firelighters and develop a new firelighter screening
tool to be subsequently evaluated and compared to the CRS and FRS. Utilising a sample
of 61 JFAIP families, data about fire-specific, family and psychosocial characteristics of
the young firelighters (5-17 years of age) at the time of their initial pre-intervention
interview was collected via the CRS, FRS, Fire Risk Interview and Child Behaviour
Checklist. A 12-month follow-up obtained information about continued firelighting
activity. Study 1 results indicated that the CRS was unable to distinguish between the
groups (repeat and non-repeat), but the FRS demonstrated some utility, accurately
detecting 86% of repeat firelighters. However it was overly inclusive, erroneously predicting that half of the non-repeat firelighters were also at risk. The results also
identified significant differences on a number of fire-specific and psychosocial variables
between repeat and non-repeat firelighters. The 25 specific items or themes across the
four instruments used to collect data demonstrating the greatest differences between the
repeat and non-repeat firelighters were combined into a new screening tool, termed the
Behaviour Risk Tool (BRT).
Study 2 was designed to measure the validity and reliability of the BRT using new
samples. In Part A the BRT was completed by the parent/guardian of 63 young people in
the JFAIP (5-17 years of age) at their initial pre-intervention interview. A minimum six
month follow up contact determined the presence or absence of repeat firelighting.
Results demonstrated the BRT had a sensitivity of 0.8 and specificity of 0.7 at the cut-off
score of 57.5. Thus the BRT detected 80% of the repeat firelighters and 70% of the nonrepeat
firelighters correctly. In Part B, the test-retest reliability and internal consistency
of the BRT was assessed. Parents/guardians of 76 children (5-17 years) in the general
population completed the questionnaire twice, two weeks apart. The results indicated high
repeatability across time (r=.93) and high internal consistency (.88-.93) for the BRT.
Hence, Study 2 found that the BRT had better sensitivity and specificity than the CRS
and FRS and was a reliable questionnaire.
The expectation is that the BRT will be used as a preliminary screening measure
in the JFAIP, to identify cases where additional mental health support may be necessary.
This is the first such tool to be developed in an Australia context. Furthermore, the JFAIP
is the first young firelighter program in Australia to adopt a screening tool of this kind.
Ideally the BRT will continue to be used over many years with many families, and
continue to be evaluated for effectiveness and further improvements.

This dissertation presents the findings of a qualitative study on understanding the motivating factors underlying repeat attendance in market research studies and the ways in which repeat attendance participants are recruited to take part in such studies. The study was approached from an interpretivist paradigm, employing the self-determination theory and the theory of self-concept maintenance. Purposive sampling was applied. The data was collected by conducting eight semi-structured interviews with participants who had taken part in numerous market research studies. Through thematic analysis, sub themes were identified from the data, combined into second-level themes and grouped into the following three overarching themes: (1) participation motivation; (2) honesty/dishonesty; and (3) recruitment procedures. It was found that participants were not only motivated by extrinsic motivators such as incentives, but that intrinsic motivators were also present. Furthermore, a level of dishonesty was also evident, not only among the participants, but among the recruiters as well.Psychology

Full textAbstract:
Over the past number of years there has been growing public pressure that action be taken to deal with the drunk driver. A major impact of this pressure has been to have the criminal justice system deal with this individual as someone who is engaged in a criminal act and from whom society must be protected. Part of this action has been to introduce mandatory sentencing for those who are repeatedly convicted for drinking and driving. The jail sentence aims to punish the individual for his actions, protect society by making it impossible for him to repeat the crime for a period of time, and in turn, hopefully deter the individual and others from committing similar offences in the future. One result of this action is illustrated by reviewing the numbers of individuals incarcerated for drinking and driving offences here in Manitoba over the past number of years. These numbers include individuals incarcerated for driving with a suspended driving licence, however this group makes up less than ten percent of the total admissions cited. In 1982 there were 761 admissions to provincial institutions for drinking and driving offences; in 1983 there were 1083 admissions; in 1984 there were 1031 admissions; and in 1985 there were 943 admissions. In total this group of offenders accounted for 3791 admissions to the provincial correctional system. The impact of this population is best judged by looking at the total number of sentenced adults admitted to provincial custody. In 1982-83 there were 4152 total admissions in 1983-84 there were 4457 admissions; and in 1984-85 there were 4916 admissions (Statistics Canada and Manitoba Provincial Statistics, 1987). This would suggest that drunk drivers make up almost a quarter of the provincial jail populations at any given time. The interpretation which accompanied the provincial statistics identified increased enforcement of drinking and driving laws as a major contributing factor to growing jail admissions (Manitoba Provincial Statistics, 1987). The existence of this significant population raises some basic questions. Who are the people that are being incarcerated for drinking and driving? What, if any, special needs or characteristics do they possess? What forces interact to bring them into contact with the criminal justice system? And what is the nature of the experience they have while in the care of the correctional system? From the perspective of social work within the correctional system questions have to be asked regarding the impact this intervention has on the client. What program initiatives are undertaken to accommodate the special needs of this client group? And, what impact does these efforts have on the client? Not only does one want to describe the population in question, one also wishes to develop an understanding of the problem from a social work perspective. The basic foundations of social work practice are stated in Pincus and Minahan (1973) under the heading "Purpose of Social Work."

Full textAbstract:
Landtagswahlergebnisse in der BRD werden von empirischen Wahlforschern häufig als aktuelle Stimmungsbarometer für die Bundespolitik interpretiert. Bei dieser Interpretation von Landtagswahlen als \"Bundestestwahlen\" wird jedoch häufig vernachlässigt, dass Landtagswahlen überwiegend auch Regionalwahlen sind und landestypischen Dynamiken folgen. Empirische Untersuchungen zu Bestimmungsfaktoren von Landtagswahlverhalten wurden in Deutschland bis dato entweder in Form von qualitativen Einzelfallanalysen oder als Aggregatdatenanalysen der amtlichen Wahlstatistiken durchgeführt. Eine direkte und vergleichende Quantifizierung der Effektstärken mit Survey-Daten wurde allerdings bislang nicht vorgenommen. Die vorliegende Studie wertet deshalb im Rahmen eines replikativen Surveys 17 Landtagswahlstudien aus. So können die Effektstärken der individuellen Bewertung der Bundes- versus der Landesparteien auf die Landtagswahlentscheidungen direkt verglichen werden. Als Fazit zeigt sich, dass in Westdeutschland die Beurteilung der Landesparteien einen stärkeren Einfluss auf die individuelle Landtagswahlentscheidung ausübt als die Beurteilung der Bundesparteien. In Ostdeutschland prägt dagegen bei Landtagswahlen die bundespolitische Dimension das Abstimmungsverhalten der Wähler stärker. Die Parteipolitikverflechtung zwischen Landes- und Bundesebene ist somit bei Landtagswahlen in Ostdeutschland erheblich stärker ausgeprägt als in den alten Bundesländern.:Einleitung; Theoretische Grundlagen der bundespolitischen Parteipolitikverflechtung bei Landtagswahlen; Empirischer Test der Parteipolitikverflechtung bei Landtagswahlen; Diskussion und AusblickElectoral studies often interpret German regional election results ("Landtagswahlen") as barometers of public opinion on federal governmental parties'' performance. However, while interpreting German regional elections as "test-elections" for the national parliament, it is often underemphasised that subnational elections often follow a unique regional dynamics. So far, empirical investigations on the determinants of German regional elections consist either in qualitative case studies or aggregate analyses of official statistics. A quantitative study of individual-level survey data, comparing directly the explanatory power of the federal versus the subnational level, is still lacking. Conducting a repeated survey design, we analyse data from 17 German regional election surveys. Thus, the effects of individual assessments of federal parties versus their subnational counterparts on subnational voting preferences can be directly compared. The conclusion of our analyses can be summarized as follows: In Western Germany, the valuation of subnational parties has a stronger impact on individual voting preferences in subnational elections than the valuation of the federal parties has. However, in Eastern Germany, the federal dimension has a comparatively stronger effect. Hence, the federal – regional ("Länder") party system linkage is clearly stronger in Eastern than in Western Germany.:Einleitung; Theoretische Grundlagen der bundespolitischen Parteipolitikverflechtung bei Landtagswahlen; Empirischer Test der Parteipolitikverflechtung bei Landtagswahlen; Diskussion und Ausblick

Full textAbstract:
Text in English with abstracts in English, isiZulu and XhosaThis research applies the Near Repeat Calculator (NRC) to identify near repeat residential burglary patterns in the Hillcrest (KZN) policing area for the first time. A total of 490 residential burglaries, over a 12-month period, reported to Hillcrest police station were mapped (geocoded) and the near repeat calculations were visualised using the Geographic Information Systems (GIS). The month-to-month near repeat calculations are analysed and suggest that the NRC is a valuable tool that can predict the space-time locations of near repeat residential burglaries in the Hillcrest policing area.
Lolu cwaningo lusebenzisa i-Near Repeat Calculator (NRC) ukuhlonza amaphethini okuphindaphindeka kwezigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest (KZN). Izigameko zokugqekezwa kwamakhaya ezingama-490 ezabikwa esiteshini samaphoyisa sase- Hillcrest esikhathini esiyizinyanga eziyi-12 zaboniswa emfanekisweni webalazwe lendawo (geocoded) futhi izilinganiso zamathuba okuthi ziphinde zenzeke izigameko zokugqekezwa kwamakhaya zaboniswa ngokuthi kusetshenziswe umfanekiso owenziwe nge-Geographic Information Systems (GIS). Kwahlaziywa amathuba enyanga nenyanga okuphindaphindeka kwezigameko, futhi imiphumela eyatholakala kulokhu iyabonisa ukuthi i-NRC iyithuluzi eliwusizo impela elingabikezela izindawo nesikhathi lapho kungaphinda futhi kwenzeke khona izigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest.
Olu phando lusebenzisa uhlobo lokubala olwaziwa ngokuba yiNear Repeat Calculator (NRC) ngenjongo yokubona isimbo sokuqhekezwa kwezindlu zabantu kummandla ophantsi kwamapolisa aseHillcrest (eKZN). Kuqwalaselwe ama-490 eziganeko zoqhekezo lwemizi ezaxelwa emapoliseni aseHillcrest kwisithuba seenyanga ezili-12, kwaye uhlobo lokubala oluqikelela ukuphindwa kweziganeko zoqhekezo luboniswe ngokusebenzisa inkqubo ekuthiwa yiGeographic Information Systems (GIS). Ubalo oluqikelela ukuphindwa kweziganeko luphononongiwe kwinyanga nenyanga, kwaye iziphumo zibonisa ukuba iNRC sisixhobo esinexabiso, esinokukwazi ukuqikelela indawo nexesha apho kunokuphinda kuqhekezwe khona kummandla ophantsi kwamapolisa aseHillcrest.

Full textAbstract:
This thesis examines landscape change from 1889 to the present within the foothills-parkland ecoregion of Waterton Lakes National Park (WLNP) in southwestern Alberta, Canada. Land cover dynamics are explored qualitatively and quantitatively using Geographical Information Systems and a combination of historical and contemporary data sources including: (1) Dominion Land Survey (DLS) transect records (1889), (2) repeat oblique photographs (1914 and 2004) and repeat aerial photography (1939 and 1999). Results indicate a consistent increase in woody vegetation cover, particularly aspen forest cover, within the foothills-parkland since 1889, largely at the expense of native grasslands. The primary drivers of these changes likely include: climatic influences, changes to the historical grazing regime, the suppression of natural fire cycles and the cessation of First Nations’ land management practices. This research illustrates the value of integrating multiple historical data sources for studying landscape change in the Canadian Rockies, and explores the implications of this change for ecological restoration in the foothills-parkland of WLNP.

Full textAbstract:
Intra-archipelago waterways, including tidal strait networks, present a complex set of barriers to, and conduits for sediment transport between marine basins. Tidal straits may also be the least well understood tide-dominated sedimentary environment. To address these issues, currents, sediment transport pathways, and seabed sedimentology & geomorphology were studied in the central Salish Sea (Gulf and San Juan Islands region) of British Columbia, Canada and Washington State, USA. A variety of data types were integrated: 3D & 2D tidal models, multibeam bathymetry & backscatter, seabed video, grab samples, cores and seismic reflection. This dissertation included the first regional sediment transport modelling study of the central Salish Sea. Lagrangian particle dispersal simulations were driven by 2D tidal hydrodynamics (~59-days). It was found that flood-tide dominance through narrow intra-archipelago connecting straits resulted in the transfer of sediment into the inland Strait of Georgia, an apparent sediment sink. The formative/maintenance processes at a variety of seabed landforms, including a banner bank with giant dunes, were explained with modelled tides and sediment transport. Deglacial history and modern lateral sedimentological and morphological transitions were also considered. Based on this modern environment, adjustments to the tidal strait facies model were identified. In addition, erosion and deposition patterns across the banner bank (dune complex) were monitored with 8-repeat multibeam sonar surveys (~10 years). With these data, spatially variable bathymetric change detection techniques were explored: A) a cell-by-cell probabilistic depth uncertainty-based threshold (t-test); and B) coherent clusters of change pixels identified with the local Moran's Ii spatial autocorrelation statistic. Uncertainty about volumetric change is a considerable challenge in seabed change research, compared to terrestrial studies. Consideration of volumetric change confidence intervals tempers interpretations and communicates metadata. Techniques A & B may both be used to restrict volumetric change calculations in area, to exclude low relative bathymetric change signal areas.Graduate
