Internal control, corruption and money laundering

The global financial crises created a different context for the economic growth and globalization. In the last few years, five risks have been designated as “risks to watch”, as survey respondents assessed them with high levels of variance and low levels of confidence while experts[1] consider they may have severe, unexpected or underappreciated consequences: cyber-security, demographic challenges, resource security, retrenchment from globalization, weapons of mass destruction. Strongly connected to these risks others are important to analyze: corruption, illegal trade and money laundering. There is a strong relation between corruption and money laundering. During the economic crunch the level of corruption and fraud had scientifically increased.Internal control could be a good instrument to reduce corruption and to stop the illegal trade and money laundering. Internal control is a dynamic integral process that is continuously adapting to the changes an organization is facing[1] www.weforum.org – The Global Risks Report 2010-2011

A personal journey of change: 20 years introducing technology inside and outside of the Organic Chemistry classroom.

Lectures lacking in student engagement have been shown to be largely ineffective with respect to learning and knowledge retention (Halloun, 1985) particularly with conceptually difficult courses such as organic Chemistry. Deeper learning and critical thinking skills are gained through active participation inside and outside of the classroom ( Crouch & Mazur, 2001; Flynn, 2015; Prince, 2004; Wieman et al., 2014). My first realization that there had to be a better way than passive lecture came in 1997. Students blindly copied reactions and mechanisms off the blackboard without comprehending. I wrote at such a fast pace, covering multiple black boards that sometimes students had not finished copying what I had written by the time I started erasing the first board. My first solution was to create course notes with blanks so that we could work on questions together. However, with increasing accessibility and affordability of digital devices the way people learn and expect to be taught has fundamentally changed. Thus, I gradually shifted to online assignments, in-class student response systems and online course material to facilitate flipping the classroom. The next step in my journey in utilizing technology for promoting student success and engagement was the development and use of an interactive online textbook with weekly reading assignments. We will discuss the gradual and then accelerated introduction of technology into and outside of the classroom. We will share student perceptions of the various course elements based on survey responses, the impact these changes have had on student success and discuss the changing expectations of students.

Eighty years of food-web response to interannual variation in discharge recorded in river diatom frustules from an ocean sediment core.

Little is known about the importance of food-web processes as controls of river primary production due to the paucity of both long-term studies and of depositional environments which would allow retrospective fossil analysis. To investigate how freshwater algal production in the Eel River, northern California, varied over eight decades, we quantified siliceous shells (frustules) of freshwater diatoms from a well-dated undisturbed sediment core in a nearshore marine environment. Abundances of freshwater diatom frustules exported to Eel Canyon sediment from 1988 to 2001 were positively correlated with annual biomass of Cladophora surveyed over these years in upper portions of the Eel basin. Over 28 years of contemporary field research, peak algal biomass was generally higher in summers following bankfull, bed-scouring winter floods. Field surveys and experiments suggested that bed-mobilizing floods scour away overwintering grazers, releasing algae from spring and early summer grazing. During wet years, growth conditions for algae could also be enhanced by increased nutrient loading from the watershed, or by sustained summer base flows. Total annual rainfall and frustule densities in laminae over a longer 83-year record were weakly and negatively correlated, however, suggesting that positive effects of floods on annual algal production were primarily mediated by "top-down" (consumer release) rather than "bottom-up" (growth promoting) controls

Young children's experiences of their hospitalisation for Cardiac surgery

Student no 9500767A Masters Report - School of TherapeuticsThe aim and objectives of this study were to explore, interpret and describe young children’s experiences of hospitalisation for cardiac surgery and to describe their parents’ opinions regarding significant changes in the children one month after discharge. A qualitative design, grounded in phenomenology was used. Semi-structured interviews were conducted with the children prior to discharge and with their parents one month later. The children’s interviews were augmented by drawings, which were used to keep the children focused and to highlight themes that were not identified from their verbal accounts of hospitalisation. The expertise of a clinical psychologist was sought for the analysis of the children’s drawings. The results of the analysis of the drawings supported the children’s verbal accounts of their experiences in hospital. Children’s interviews revealed that young children experience and cope with hospitalisation for cardiac surgery very differently. Parents’ presence, pain and boredom were dominant themes that emerged from the children’s interviews. Behavioural changes and emotional responses included withdrawal, tearfulness, disturbed sleep patterns, sadness, fear, anger and happiness. Parents’ interviews one month after discharge revealed a lack of communication between the nurses and the children. iv It is recommended that further research be conducted with older children to determine the effects of stringent visitation regulations followed in the paediatric intensive care setting

PROMOTING ENGAGEMENT IN DIGITAL WEIGHT LOSS INTERVENTIONS

Obesity has reached epidemic proportions in the United States. Digital weight loss interventions are effective for weight loss, and engagement in digital weight loss interventions, especially self-monitoring, is crucial for success. Given that engagement with self-monitoring consistently declines over time, the purpose of this dissertation was to understand effective patterns of engagement with self-monitoring, as well as whether and to what extent novel approaches for simplified self-monitoring enhance intervention engagement. Aim One used latent class growth modeling with another mixture layer to identify groups of participants based on trajectories of engagement with self-monitoring of weight, diet, and physical activity among overweight or obese adults participating in an effective 12-month digital weight loss intervention (N = 363). Four engagement patterns emerged: never-engagers, low/declining engagers, early engagers, and sustained-engagers. Predicted percent weight loss was clinically significant at 12 months for both sustained-engagers (10.4%) and early engagers (5.1%), but not for low/declining (1.3%) or never-engagers (0.48%). Aim Two was a 3-month randomized controlled pilot trial that compared the feasibility and efficacy of simplified dietary self-monitoring targeting Red Food reduction (i.e. limiting high-calorie, high-fat foods) to simplified dietary self-monitoring targeting Green Food promotion (i.e. maximizing fruits, vegetables, lean proteins, etc.) on engagement with dietary self-monitoring, self-reported weight change, and dietary intake at 3 months among overweight or obese young adults (N = 60). There were no between-group differences in engagement with dietary self-monitoring over 3 months. A greater proportion of participants in the Red Food group (23.1%) achieved a clinically meaningful 5% weight loss compared with the Green Food group (0%). Diet quality significantly increased for participants in both groups, and there were no between-group differences in change over time. Simplified dietary self-monitoring targeting Green Food promotion may improve diet quality, however, limiting Red Foods appears to be a more effective simplified dietary self-monitoring strategy for weight loss. By understanding effective patterns of multiple measures of engagement with self-monitoring over time, and exploring novel ways to promote greater engagement with dietary self-monitoring, this dissertation contributes to the body of research seeking to inform targeted efforts to promote sustained engagement with self-monitoring, which could improve the efficacy of digital weight loss interventions.Doctor of Philosoph

The regulation of cellular CD23 gene expression by Epstein-Barr virus latent proteins in immortalised cells

Only EBV-infected B lymphocytes which express the B cell activation marker CD23 are capable of establishing immortalised cell lines. Epstein-Barr virus determined nuclear antigen 2 (EBNA-2) is essential for EBV-induced growth transformation (Cohen, et al, 1989) and can specifically upregulate CD23 gene expression (Wang, et al, 1987). The regulation of CD23 gene expression is likely to be an important factor in EBV-induced B cell growth transformation. The cellular CD23 promoter and EBV TP-1 promoter have previously been shown to be transactivated by EBNA-2 (Wang, et al, 1991, Le Roux, et al, 1993). Studies have also shown that while EBNA-3A itself has no effect on the TP-1 promoter, it can repress EBNA-2-mediated transactivation in a B cell background (Le Roux, et al, 1994). Homologies have been shown between sequences present in the EBV TP-1 EBNA-2 responsive element and other functionally similar sequences which are found in the CD23 promoter region. The purpose of this study was to explore the regulation of CD23 gene expression by the EBV latent proteins EBNA-2 and EBNA-3A. The most common reporter gene used in transfection studies is CAT (chloramphenicolacetyl transferase), usually assayed using a radioisotopic method. To obviate the need to use a radioassay, an alternative reporter plasmid was constructed and tested in a range of cell backgrounds. This construct consisted of the CD23 promoter cloned upstream of the PAP gene (placental alkaline phosphatase). The assay involves a colorimetric reaction, and is a simpler and cheaper reporter assay (Henthorn, et al, 1988). In order to identify relevant sequence modules in the CD23 promoter, deletion mutants of CD23CAT were constructed for use in co-transfection assays with plasmids encoding EBNA-2/3A. A strategy based on using the nuclease BAL 31 was designed to create nested mutations. Fragments of the CD23 promoter including the EBNA-2 responsive elements were also amplified by PCR for cloning upstream of CAT

A Critical Review of Decision Support Systems Foundational Articles

Abstract Decision Support Systems (DSS) is a mature field of study with an extensive conceptual and empirical literature. This research study provides a starting point for learning and reviewing the foundation literature of the field. Decision support and analytics researchers can benefit from revisiting the methodologies, identifying under-explored ideas, and hopefully identifying visionary concepts from thought leaders who established the DSS research stream. This article reports a systematic examination of the DSS foundational literature published in MIS Quarterly during its first fifteen years of publication -- 1977-1991. In addition to examining the relevance of these articles to current and future research, the findings of the study provide a reference point of DSS research categories. Articles were categorized in terms of theory, methods, concepts and perspectives about computerized decision support that enrich research and encourage future exploration
