    Achieving business and IT integration is strategic goal for many organisations – it has almost become the ‘Holy Grail’ of organisational success. In this environment Enterprise Resource Planning (ERP) packages have become the defacto option for addressing this issue. Integration has come to mean adopting ERP, through configuration and without customization, but this all or nothing approach has proved difficult for many organisations. In part 1 of a 2 part update we provide evidence from the field that suggests that whilst costly, if managed appropriately, customization can have value in aiding organisational integration efforts. In part 2, we discuss in more detail the benefits and pitfalls involved in enacting a non-standard based integration strategy

    Between-site reliability of startle prepulse inhibition across two early psychosis consortia

    Prepulse inhibition (PPI) and reactivity of the acoustic startle response are widely used biobehavioral markers in psychopathology research. Previous studies have demonstrated that PPI and startle reactivity exhibit substantial within-site stability; between-site stability, however, has not been established. In two separate consortia investigating biomarkers of early psychosis, traveling subjects studies were performed as part of quality assurance procedures in order to assess the fidelity of data across sites. In the North American Prodromal Longitudinal Studies (NAPLS) Consortium, 8 normal subjects traveled to each of the 8 NAPLS sites and were tested twice at each site on the startle PPI paradigm. In preparation for a binational study, 10 healthy subjects were assessed twice in both San Diego and Mexico City. Intraclass correlations between and within sites were significant for PPI and startle response parameters, confirming the reliability of startle measures across sites in both consortia. There were between site differences in startle magnitude in the NAPLS study that did not appear to be related to methods or equipment. In planning multi-site studies, it is essential to institute quality assurance procedures early and establish between site reliability to assure comparable data across sites

    “Because it was cheap, because it was on sale”: Essential nutrient intake at USU

    The “freshman 15” is common folklore on college campuses. So too is the understanding that ramen and pizza are the breakfast, lunch, and dinner of champions and that Mountain Dew with a shot of Monster is the elixir of life. In this poster, we will seek to identify in what ways essential nutrient intake differs between college classes (e.g. freshmen, sophomores, etc.) at Utah State University, focusing specifically on water soluble vitamins. We used a convenient snowballing sample to conduct a 24 hour food recall with 5-8 participants per college class. Additionally, each interview included basic demographic information that we believed could impact nutritional intake: Employment status, income, gender, residency (on or off campus), meal plan, marital status, number of children, religious identity, transportation access, and the number of credits that each participant is currently taking, as well as height, weight, and age. Water soluble vitamins are constantly flushed from the body, thus they need to be replaced daily. For this reason, students should be eating foods that contain these vitamins every day. We utilized the USDA Food and Nutrient Database for Dietary Studies (FNDDS) dataset to calculate water-soluable vitamin values for each participant based upon their 24 hour diet recalls. We then entered these values into SPSS and compared to see whether they differed significantly from the recommended dietary allowance (RDA) for each participant’s age and gender. Where RDA values are not available we used adequate intake (AI) values. Because participant observation is an integral part of any anthropological study, we also accompanied and observed participants when they went to the grocery store, to understand what factors went into choosing foods

    Effects of Amphetamine on Sensorimotor Gating and Neurocognition in Antipsychotic-Medicated Schizophrenia Patients.

    Prepulse inhibition (PPI) of startle is being explored both as an indicator of target engagement for, and a biomarker predicting the sensitivity to, procognitive effects of drugs. We now report the effects of the pro-attentional drug, d-amphetamine, on PPI and neurocognition in antipsychotic-medicated schizophrenia patients and healthy subjects (HS) who were also tested in a targeted cognitive training (TCT) module. 44 HS and 38 schizophrenia patients completed a double-blind, placebo-controlled crossover study of the effects of a single dose of amphetamine (10 mg po) on PPI and MATRICS Consensus Cognitive Battery (MCCB) performance; TCT results were previously reported from 60 of these subjects. Moderators predicting AMPH sensitivity were assessed, including the rs4680 single-nucleotide polymorphism for catechol-O-methyltransferase (COMT). After placebo, patients exhibited PPI deficits with 60 ms prepulse intervals; these deficits were 'rescued' by amphetamine. The magnitude of amphetamine-enhanced PPI was greater in patients than in HS (p<0.032), and was associated with positive symptoms (p<0.007), antipsychotic load (p<0.015), hedonic effects of AMPH (p<0.003), and with the presence of at least one methionine allele in rs4680 (p<0.008). No significant effects of amphetamine on MCCB performance were detected in either group, though pro-attentional effects of amphetamine in patients were associated with greater amphetamine-enhanced TCT learning. Amphetamine acutely 'normalized' PPI in antipsychotic-medicated schizophrenia patients; no concurrent acute neurocognitive changes were detected by the MCCB. Findings suggest that in the context of appropriate antipsychotic medication, a low dose of amphetamine enhances brain processes associated with higher function in schizophrenia patients, without accompanying changes in MCCB performance
