The Relationship Between Frequency of Incest and Relational Outcomes with Family-of-Origin Characteristics as a Potential Moderating Variable

Baxter, Kathleen Diane 18 March 2013 (has links) (PDF)
As we examined research on the relational effects of incest on survivors, several researchers noted that some of the negative outcomes may be moderated by certain family characteristic variables. Using RELATE data, we examined a subsample of females and males who reported being survivors of incest in childhood and compared them on key family-of-origin processes such as mother and father's marital satisfaction as well as family violence. We used a path analysis to determine whether family processes, specifically functional parents' marriage and low physical violence, moderate the relationship between incest and marital quality in adulthood. Functional family-of-origin processes significantly moderated the relationship between sexual child abuse and adult marital quality for female survivors (β = -.55, p <.001) and for male survivors (β = -.43, p <.001). Therapists who work with survivors of sexual abuse should not only recognize the effects of childhood sexual abuse on individual and relational functioning, but should also recognize the familial context in which the incest occurred as well as the long-term relational effects on an adult survivor. The results of this study imply that family therapy should be part of the treatment and prevention of sexual abuse.

Facilitating Corporate Social Innovation in Partnerships : A multiple case study on the origin of corporate social innovation in partnerships

Högbom Brinkmann, Christoffer, Berglund, Erik January 2022 (has links)
Background: The increase in public awareness and rising social expectations have changed the role businesses have in modern society, as they are expected to deliver both organizational and social value. Despite this, most social engagements have previously been philanthropic, which is argued to only scratch the surface of societal issues. The concept of CSI was therefore coined, and it focuses on leveraging companies’ core capabilities to be innovative while forming collaborations and partnerships between units within the company and external organizations to mend social ills. This concept has been described to yield excellent outcomes; however, the initiation and implementation of CSI have been vaguely depicted in literature.  Purpose: Previous research of CSI has centralized around the outcomes, such as innovation capabilities and competitive advantage, and regularly compared them to more basic philanthropic initiatives. Therefore, the purpose of this research is to focus on the origin of CSI in organizations and how partnerships can facilitate its generation. The thesis further intends to collect and summarize the various definitions of CSI to establish the occurrence of CSI in various organizations.  Method: This research adopted a critical realism philosophical stance to perform a multiple case study. We did this with a qualitative research design, including eight semi-structured interviews with participants from different organizations currently engaged in partnerships. The data were analyzed using thematic analysis, which we practically performed using an abductive approach to code data and the subsequent thematization. The findings of this thesis are then, using theory matching and triangulation, presented to discover alternative explanations for the facilitating factors of CSI in partnerships.  Conclusion: We consolidated previous research to construct a definition of CSI. This consolidated concept was used to evaluate the initiatives in the participants’ partnerships. We used thematic analysis to define three distinct facilitating themes for generating CSI in partnerships: People, Partnership Conditions, and Institutional Entity Structure. Conclusively, the purpose was achieved as our findings and subsequent analysis indicates that the three realized themes substantially influence CSI generation. It was found that these facilitating factors are interdependent, as the underdevelopment of one area negatively influenced the ability to engage in CSI.

Forecasting future delivery orders to support vehicle routing and selection / Förutsägelse av framtida leveransorder för att stödja val av fordon samt deras ruttplanering

Engelbrektsson, Gustaf January 2018 (has links)
Courier companies receive delivery orders at different times in advance. Some orders are known long beforehand, some arise with a very short notice. Currently the order delegation, deciding which car is going to drive which order, is performed completely manually by a (TL) where the TL use their experience to guess upcoming orders. If delivery orders could be predicted beforehand, algorithms could create suggestions for vehicle routing and vehicle selection. This thesis used the data set from a Stockholm based courier company. The Stockholm area was divided into zones using agglomerative clustering and K-Means, where the zones were used to group deliveries into time-sliced Origin Destination (OD) matrices. One cell in one OD-matrix contained the number of deliveries from one zone to another during one hour. Long-Short Term Memory (LSTM) Recurrent Neural Networks were used for the prediction. The training features consisted of prior OD-matrices, week day, hour of day, month, precipitation, and the air temperature. The LSTM based approach performed better than the baseline, the Mean Squared Error was reduced from 1.1092 to 0.07705 and the F1 score increased from 41% to 52%. All features except for the precipitation and air temperature contributed noticeably to the prediction power. The result indicates that it is possible to predict some future delivery orders, but that many are random and are independent from prior deliveries. Letting the model train on data as it is observed would likely boost the predictive power. / Budföretag får in leveransorder olika tid i förväg. Vissa order är kända lång tid i förväg, medan andra uppkommer med kort varsel. I dagsläget genomförs orderdelegationen, delegering av vilken bil som kör vilken order, manuellt av en transportledare (TL) där TL använder sin erfarenhet för att gissa framtida order. Om leveransorder skulle kunna förutsägas i förväg kan fordonsrutter och fordonsval föreslås av algoritmer. Denna uppsats använde sig utav ett dataset från ett Stockholmsbaserat budföretag. Stockholmsområdet delades in i zoner med agglomerativ klustring och K-Means, där zoner användes för att gruppera leveranser in i tidsdelade Ursprungsdestinationsmatriser (OD-matriser).  En cell i en OD-matris innehåller antalet leveranser från en zon till en annan under en timme. Neurala nätverk med lång-kortsiktsminne (LSTM) användes för förutsägelsen. Modellen tränades på tidigare OD-matriser, veckodag, timme, månad, nederbörd, och lufttemperatur. Det LSTM-baserade tillvägagångssättet presterade bättre än baslinjen, det genomsnittliga kvadratfelet minskade från 1,1092 till 0,07705 och F1-poängen ökade från 41% till 52%. Nederbörd och lufttemperatur bidrog inte märkbart till förutsägelsens prestation. Resultatet indikerar att det är möjligt att förutse vissa leveransorder, men att en stor andel är slumpmässiga och oberoende från tidigare leveranser. Att låta modellen tränas med nya data när den observeras skulle troligtvis öka prognosförmågan.

Trace element analysis of human tooth enamel by laser ablation-inductively coupled plasma-mass spectrometry for estimation of region of origin

Jones, Meaghan Elisabeth 22 January 2016 (has links)
Tooth enamel is among the most durable substances in the human body and as such has high recoverability in forensic anthropology cases. Its crystalline hydroxyapatite matrix has a slightly variable chemical composition which incorporates biologically available trace elements. The trace elements are derived from an individual's diet and the water he or she consumes during the period of enamel formation. As a result, trace element profiles of enamel can reflect the geology, pollution, and certain cultural dietary factors of the area in which the individual resided during this period. This research examines a sample of teeth with known demographic information from the Antioquia Modern Skeletal Reference Collection in Medellin, Colombia. A sample set of 75 teeth from 61 individuals born in areas throughout northwestern Colombia were analyzed using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), a minimally destructive, semi-quantitative technique. Analysis was performed at the Center for Archaeology, Materials, and Applied Spectroscopy (CAMAS) at Idaho State University. 33 elements were analyzed in the sample. Nonparametric methods were used to assess the relationship between elemental profiles and region of origin. Sr, Mo, Ag, Ba, Eu, and Tm concentration profiles were found to vary among regional groups. Al, Ni, Cr, Mn, Co, Sr, Cd, Sb, Sm, Eu, and U were found to predict region of origin. Differences in municipality were classified with 72% accuracy, variation across the department of Antioquia was classified with 67% accuracy, and the age of the geologic substrate was classified with 67% accuracy. The results suggest that trace element analysis of permanent tooth enamel may be of some use in estimating an individual's region of origin in forensic anthropological contexts. Further research with both larger sample sizes and more geographic variation is necessary.

CONSUMERS' VALUE PERCEPTIONS ON SPARKLING WINE AND PURCHASING INTENTION: THE IMPACT OF COUNTRY OF ORIGIN AND PURCHASING PURPOSES

Xinyue Li (14232929) 09 December 2022 (has links)
<p>  </p> <p>The purpose of the present study was to investigate the influence of purchasing purposes and country of origin on consumer’s purchasing intentions for sparkling wine, considering the effect of consumer’s value perceptions on the product. Two study populations were investigated: general U.S. wine consumers and self-identified food and beverage practitioners. It was found that for the general U.S. wine consumers, buying wine for gift giving or self-gifting would result in different purchasing intention and perceived emotional-social value, but Country of Origin (e.g., French Champagne or U.S. Sparkling Wine) did not result in any differences in purchasing intentions or perceived values. The practitioner group did not note any significant differences  between scenarios given the purchasing purposes and country of origin on their purchasing intentions and perceived values. Correlations of perceived emotional-social value, perceived price value and purchasing intention were found. Several practical and theoretical implications were presented. </p>

Nature and Origin of Sediments Infilling Buried Bedrock Valleys Adjacent to the Niagara Escarpment, Southern Ontario, Canada

Meyer, Patricia Anne 08 1900 (has links)
<p> The Paleozoic bedrock surface of southern Ontario is dissected by an interconnected system of buried bedrock valleys that are infilled with thick successions of glacial, interglacial and fluvial sediments. These valleys can be several kilometers wide, reach depths of up to 250m and the coarse-grained units are known to host significant local and regional groundwater aquifers.</p> <p> Two buried bedrock valleys located near the Niagara Escarpment in the Region of Halton were under investigation in the fall of 1999 for their potential to host additional municipal groundwater aquifers to supply drinking water to the towns of Milton and Georgetown. Detailed logging of sediment recovered from eleven continuously-cored boreholes, drilled within the Georgetown and Milton bedrock valleys, forms the basis for this study. Four distinct facies types were identified within the borehole cores including sand, gravel, fine-grained sediment and diamict (sand-rich, mud-rich and clast-rich). These four facies types were used to subdivide the cores into six stratigraphic units based on textural characteristics and stratigraphic position. These six units form a stacked succession of aquifers and aquitards within the valley infill with two stratigraphic units being identified as potential municipal aquifers.</p> <p> The Georgetown buried bedrock valley contains narrow bedrock channel interpreted to have been fluvially incised, lying within a broader flat-bottom valley likely formed by glacial scouring of the bedrock. It is feasible that regional bedrock jointing created a zone of weakness that was later exploited by a drainage network. The valley infill sediments record the approach of the Laurentide Ice Sheet into southern Ontario during the Early to Mid-Wisconsin, and the subsequent overriding of the area during the Late Wisconsin period.</p> / Thesis / Master of Science (MSc)

Sedimentology of the basal Stoddart Formation (Upper Mississippian) in the area of Josephine Field, northwest Alberta

Hrabi, Robert Blair 04 1900 (has links)
<p> A sedimentogical and petrological examination of the basal sands of the Stoddart Formation in the area of Josephine field has been undertaken. The determination of the depositiianal environment and the history of sedimentation of the basal Stoddart sands are the objectives of this study. </p> <p>The thick sands at the base of the Stoddart Formation which have a blocky gamma ray response consist of fine-grained sandstone dominated by angle of repose cross-bedding. The sedimentary structures, stratification types, composition and facies relationships of these sands indicate that they are of a coastal aeolian origin.</p> <p>The compositional, textural and surface texture characteristics of these sands were studied under petrographic, cathodolumenescent and scanning electron microscopes. Observations indicate that the above criteria can be used to support the interpretation of an aeolian origin for the cross-bedded sands of the basal Stoddart Formation. </p> <p>The sands of the basal Stoddart show rapid transitions between sub-aerial and marine environments. These rapid changes are believed to be caused by sudden sea level fluctuations resulting from movement of reactivated faults in the Peace River arch area. </p> / Thesis / Bachelor of Science (BSc)

ESG, Legal Origin and Corporate Governance : From Voluntary to Mandatory Reporting in the European Union

Vaarala, Eric January 2022 (has links)
The study is based on a hypothetical deductive approach. The study applies a quantitative method. The material covers 3926 firm years between 2007–2019. The data studied is obtained from the ASSET4 database. Analysis of data has taken place in the statistics program IBM SPSS. The study is based in corporate governance where the balance between shareholders and stakeholders forms the basis together with the countries' legal origins, i.e. how the legal traditions of different countries affect firms' reporting. To analyze this, two parts are used, a period of voluntary reporting of ESG(2007-2016) and a period covering the regulatory framework implemented in the European Union where mandatory reporting (2017-2019) of non-financial information such as environment and social aspects were introduced for larger firms in 2017. Based on this, a comparison is made whether higher ESG reporting is achieved in the voluntary or mandatory environment.  The study finds evidence that higher ESG reporting is achieved in the mandatory reporting and that the countries' legal differences decrease during the mandatory reporting period. The results show that firms of Scandinavian legal origin have lower ESG reporting and that a concentrated ownership structure leads to a lower ESG reporting.
