“Tänk efter före” - föräldrars tankar om fenomenet sharentingBenjaminsson, Ellinor, Magnusson, Stina January 2020 (has links)
The purpose of the study was to examine parents’ perspectives and thoughts regarding posting images of their children on social media, a phenomenon known as sharenting. This phenomenon presents the growing number of technological concerns for social work practice and research. The study sought to explore ideas of children’s rights to privacy, consent, and integrity in relationship to sharenting. The study applied a qualitative method in the form of semi-structured interviews in order to gather empirical data. The data consisted of eight parents with children between the ages of 0 to 13 years who were recruited from a parenting group on Facebook and all self-reported as frequent users of social media. The results of the study showed that parents are very split in their views of sharenting; some see it as problematic while others see it as a possibility to share information to friends and family and coping with being a parent. The result also shows that parents believe that more information regarding consent for both children and parents from the society is needed. A conclusion made from the authors is that the field of social work must prepare for possible future problems as a result of sharenting.

DETECTION AND EXCLUSION OF FAULTY GNSS MEASUREMENTS: A PARAMETERIZED QUADRATIC PROGRAMMING APPROACH AND ITS INTEGRITYTeng-yao Yang (8742285) 23 April 2020 (has links)
<div>This research investigates the detection and exclusion of faulty global navigation satellite system (GNSS) measurements using a parameterized quadratic programming formulation (PQP) approach. Furthermore, the PQP approach is integrated with the integrity risk and continuity risk bounds of the Chi-squared advanced receiver autonomous integrity monitoring (ARAIM). The integration allows for performance evaluation of the PQP approach in terms of accuracy, integrity, continuity, and availability, which is necessary for the PQP approach to be applied to the vertical navigation in the performance-based navigation (PBN). In the case of detection, the PQP approach can also be integrated with the vertical protection level and the associated lower and upper bounds derived for the solution separation ARAIM. While there are other computationally efficient and less computationally efficient fault detection and</div><div>exclusion methods to detect and exclude faulty GNSS measurements, the strength of the PQP approach can summarized from two different perspectives. Firstly, the PQP</div><div>approach belongs to the group of the computationally efficient methods, which makes the PQP approach more favorable when it comes to detect and exclude multiple simultaneous faulty GNSS measurements. Secondly, because of the integration of the PQP approach with the integrity risk and continuity risk bounds of the Chi-squared</div><div>ARAIM, the PQP approach is among the first computationally efficient fault detection and exclusion methods to incorporate the concept of integrity, which lies in</div><div>the foundation of PBN. Despite the PQP approach not being a practical integrity monitoring method in its current form because of the combinatorial natural of the integrity risk bound calculation and the rather conservative integrity performance, further research can be pursued to improve the PQP approach. Any improvement on the integrity risk bound calculation for the Chi-squared ARAIM can readily be</div><div>applied to the integrity risk bound calculation for the PQP approach. Also, the connection between the PQP approach and the support vector machines, the application of the extreme value theory to obtain a conservative tail probability may shed light upon the parameter tuning of the PQP approach, which in turn will result in tight integrity risk bound.</div>

Profile-based comparison of user integrity and advertisement content when using different adblockers / Profilbaserad jämförelse av användarintegritet och annonser vid användning av annonsblockerareEkblad, Alice, Höglund, Anna January 2021 (has links)
Advertisements are a common way to increase the revenue for websites. All users, however, are not interested in exposing themselves to advertisements and instead avoids it by installing an ad-blocker extension to their browser. In this thesis, a data collection followed by an analysis of the created dataset has been performed, with the purpose of identifying possible user integrity issues when using the ad-blocker extensions AdBlock and Adblock Plus. The study focuses on what kind of advertisements are displayed to a user and if it depend on the used ad-blocker extension or lack thereof, regional location, and the used browser. The data collection was carried out using a Selenium-based data collection tool, which both impersonated a real user surfing the Internet and scraped data from the visited websites along the way. The data collection was performed during a period of 21 days, using five different fictional users. A critical part of the thesis has been to find out how well user profiling, in the context of distributing targeted advertisement, works depending on if an ad-blocker extension is utilized or not. The used tool visited around 162 unique URLs per session and day, resulting in a dataset for further analysis. It was concluded that few differences in the number of targeted vs. untargeted ads a user was exposed to occurred in relation to regional location and used browser. The amount of advertisement decreased with the use of an ad-blocker, however, the data indicated that the share of targeted ads, compared to untargeted, increase with the use of an ad-blocker extension.

Analýza vlivu parametrů procesu broušení na integritu obrobené plochy se zaměřením na zbytková napětí / Analysis of influence of grindig parameters on the surface integrity with a view to residual stressesDömény, Tibor January 2009 (has links)
Since grinding is often the last process of a manufactured part, caution has to be taken in order to ensure the integrity of the surface. The role of grinding induced residual stresses can be important in fatigue or wear resistance. In most cases we cannot evaluate accurately and easily their distribution. On this purpose, many scientists are working on the modeling of grinding and its effects on a many points. The main aim of this work is to analyse of residual stresses influenced by grinding parameters.

In Situ RNA Quality Control : A spatial heat map of RNA integrity with single cell resolutionCarlberg, Konstantin January 2015 (has links)
The quality of RNA is of great importance in gene expression studies. It is mostly measured using the RNA integrity number (RIN). Lately it has been shown that samples with low RIN and different fragmentation patterns could affect quality of sequencing data. For such low RIN samples a new approach has been developed by Illumina called the DV200 metric, which is the percentage of fragments >200 nucleotides. For samples with low RIN, DV200 has proved to be a better method to predict if good quality data from RNA sequencing can be generated. However, neither RIN nor DV200 provide spatial infromation on the RNA integrity. Thus, tissues with areas of heterogeneous RNA integrity, where regions of good quality RNA sequencing data could be generated from are missed. We have designed a method to spatially evaluate the RNA integrity in tissue, which we named in situ RNA QC. The method uses three probes with three different fluorophores, each bound to three specific cDNA regions synthesized from the high abundant and well conserved 18S rRNA. With the help of in-house technology from the Spatial Transcriptomics (ST) group at SciLifeLab, we enable creation of heat maps over the RNA integrity to show spatial fragmentation patterns of RNA in tissue. This could reveal the regional quality of transcripts in situ, which is crucial knowledge when selecting samples for further RNA sequencing. The assay has been tried using different tissue fixation methods in order to show a proof of concept that formalin gives shorter cDNA fragments than acetone. The generated heat-map provides a visual overview of RNA integrity in situ; hence this method could be used to select samples for sequencing by evaluation the spatial quality of RNA. For instance from fresh frozen and formalin fixated paraffin embedded (FFPE) tissue (biobanks contain large number of longterm storage FFPE samples). With this assay we will be able to determine which samples are suitable for sequencing.

Integrity issues of information created by book entriesVan der Poll, Huibrecht Margaretha 03 March 2004 (has links)
Book entries are vehicles used in accounting to accommodate non-cash transactions, timing differences and provisions. The use of book entries is a normal activity in accounting and may have their origin in accrual accounting. The management of a company may apply creative accounting techniques in the form of earnings management, in particular, adopting the practices of income smoothing and taking the so-called ‘big bath’. These practices may result in the financial manager or accountant misusing book entries. This could then lead to information of a different integrity to that which would have resulted had these creative accounting practices not been performed in the company. The question addressed in this dissertation and for which an answer is sought, is whether there is any notable difference in the integrity issues of information supplied through the accounting process and created by real transactions (real events) as opposed to information created by book entries (artificial events). The hypothesis underlying this dissertation is: The integrity of information created by book entries is based on subjective opinions because it is based on future events therefore it is not the same as integrity of information created by real transactions that is based on historical events. The new science is concerned with new guidelines, amongst other things, regarding reality, observation, objectivity, predictions and relationships among events. These new guidelines could be seen as explaining certain aspects which is relevant to the field of accounting. The attributes of a book entry are not based on reality, but are based on subjective predictions of future transactions etc. Another similarity is that a book entry is often not objective but is based on subjective observation. Notable differences were observed in the integrity of the information emerging from a real, historical event and a future event. These differences were established through the application of two research methods, namely, the use of a questionnaire and the analysis of the financial statements of 30 companies listed on The JSE Securities Exchange South Africa (JSE). The influence of book entries on certain ratios was considered, and the ratios influenced by two major book entries, namely, depreciation provision and deferred taxation, differ substantially in interpretation when the two book entries are reclassified. The results of the questionnaire also indicate that a large proportion of the financial managers in practice believe that book entries substantially influence the integrity of information. / Dissertation (MCom Financial Management Sciences)--University of Pretoria, 2003. / Financial Management / unrestricted

Effects of Watershed and Habitat Conditions on Stream Fishes in the Upper Roanoke River Watershed, VirginiaStancil, Vann Franklin 18 July 2000 (has links)
I collected fish samples and habitat data at 43 sites throughout the upper Roanoke River watershed, Virginia. Sites were separated into three watershed areas size classes: 10 - 15, 20 - 30, and 70 - 80 km². I correlated physical in-stream conditions with proportions of forest, disturbed, and herbaceous/agricultural land at various watershed-scales to determine factors affecting stream habitat. I grouped fishes into metrics commonly used in indexes of biotic integrity and created a multimetric index called the mean metric score to represent fish communities at sites. Fish variables and metric values were compared with stream habitat and watershed variables to determine primary influences on fish communities. I correlated land use at 24 spatial scales, which differed by buffer width and stream network area, with mean metric scores to determine zones of greatest influence on fish communities.
In-stream habitat conditions and amounts of forest, herbaceous/agricultural, and disturbed land varied greatly among sites. Habitat varied due to natural differences among sites, such as elevation and watershed area, and due to land use. Disturbed land use was greatest at lower elevations while forests were more abundant at higher elevations. Substrate size distribution was highly correlated with all three land use types at several spatial scales. Correlations between land use within various buffers and median particle size became stronger as larger proportions of watersheds were included in analysis.
Fish species richness increased from small to large sites by species addition. Species collected at small sites were also collected at large sites, but several species collected at large sites were absent elsewhere. For example, orangefin madtoms and bigeye jumprocks were only collected at three large sites. Fish distribution was a result of several factors such as watershed area, elevation, proportions of pools and of riffles, particle size, and land use within buffers and entire watersheds.
Sites with high mean metric scores were primarily limited to tributaries of the North and South Forks of the Roanoke River. Most sites with low mean metric scores were located near the cities of Roanoke and Salem. Forest and disturbed land use were highly correlated with mean metric scores. Elevation was also highly correlated with mean metric scores but herbaceous/agricultural land use was not. Correlations between percent forest within 24 buffers and mean metric scores were highest for small stream network areas and declined as more land farther from sites was included for analysis. Correlations between disturbed land use and mean metric scores were strong regardless of the area considered. Mean metric scores declined precipitously as disturbed land use within watersheds and buffers increased from 0 to 10 %, but reached a plateau at 10 to 20 % after which increases in disturbed land use did not result in lower mean metric scores.
My results suggest that species addition and ecological shifts from more generalized to more specialized species occur with increased stream size. Forested buffers are important for maintaining ecological integrity, and buffers along sites with adequate integrity should be candidates for riparian restoration. Future development should be concentrated in watersheds that are already developed and reforestation of riparian areas in developed watersheds may reduce the impacts of watershed-level disturbance. / Master of Science
