Enterprise Architecture Documentation: Current Practices and Future Directions

Over the past decade Enterprise Architecture (EA) management matured to a discipline commonly perceived as a strategic advantage. Among others, EA management helps to identify and realize cost saving potentials in organizations. EA initiatives commonly start by documenting the status-quo of the EA. The respective management discipline analyzes this so-called current state and derives intermediate planned states heading towards a desired target state of the architecture. Several EA frameworks describe this process in theory. However, during practical application, organizations struggle with documenting the EA and lack concrete guidance during the process. To underline our observations and confirm our hypotheses, we conducted a survey among 140 EA practitioners to analyze issues organizations face while documenting the EA and keeping the documentation up to date. In this paper we present results on current practices, challenges, and automation techniques for EA documentation in a descriptive manner

Biochemical and Molecular-Genetic Characterization of SFD1’s Involvement in Lipid Metabolism and Defense Signaling

The Arabidopsis thaliana SFD1 (suppressor of fatty acid desaturase deficiency1) gene (also known as GLY1) is required for accumulation of 34:6 (i.e., 18:3–16:3) monogalactosyldiacylglycerol (MGDG) and for the activation of systemic acquired resistance (SAR), an inducible defense mechanism that confers resistance against a broad spectrum of pathogens. SFD1, which has been suggested to be involved in lipid-based signaling in SAR, contains a putative chloroplast transit peptide and has glycerol-3-phosphate synthesizing dihydroxyacetone phosphate (DHAP) reductase (also referred as glycerol-3-phosphate dehydrogenase) activity. The goals of this study were to determine if the DHAP reductase activity and chloroplast localization are required for SFD1’s involvement in galactolipid metabolism and SAR signaling. The crystal structure of a Leishmania mexicana glycerol-3-phosphate dehydrogenase was used to model SFD1 structure and identify Lys194, Lys279, and Asp332 as potential catalytic site residues in SFD1. Mutational analysis of SFD1 confirmed that Lys194, Lys279, and Asp332 are critical for SFD1’s DHAP reductase activity, and its involvement in SAR. SFD1 proteins with these residues individually substituted by Ala lacked DHAP reductase activity and were unable to complement the SAR defect of the sfd1 mutant. The SFD1–Ala279 protein was also unable to restore 34:6-MGDG content when expressed in the sfd1 mutant. In vivo imaging of a green fluorescent protein-tagged SFD1 protein demonstrated that SFD1 is targeted to the chloroplast. The N-terminal 43 amino acids, which are required for proper targeting of SFD1 to the chloroplast, are also required for SFD1’s function in lipid metabolism and SAR. Taken together, these results demonstrate that SFD1’s DHAP reductase activity is required in the chloroplast for lipid metabolism and defense signaling

Phospholipidome of Candida: each species of Candida has distinctive phospholipid molecular species

By employing electrospray ionization tandem mass spectrometry (ESI-MS/MS), the phospholipidomes of eight hemiascomycetous human pathogenic Candida species have been characterized. Over 200 phospholipid molecular species were identified and quantified. There were no large differences among Candida species in phosphoglyceride class composition; however, differences in phosphoglycerides components (i.e., fatty acyl chains) were identified. In contrast, differences in sphingolipid class composition as well as in molecular species were quite evident. The phospholipid compositions of C. albicans, C. glabrata, C. parapsilosis, C. kefyr, C. tropicalis, C. dubliniensis, C. krusei, and C. utilis could be further discriminated by principal component analysis. Notwithstanding that a single strain of each species was analyzed, our data do point to a typical molecular species imprint of Candida strains

Antibiotic Prophylaxis with Trimethoprim-Sulfamethoxazole versus No Treatment after Mid-to-Distal Hypospadias Repair: A Prospective, Randomized Study

Purpose. To evaluate the impact of prophylactic antibiotics after distal hypospadias repair on postoperative bacteriuria, symptomatic urinary tract infection, and postoperative complications in a prospective, randomized trial. Materials and Methods. Consecutive patients aged 6 months to 2 years were enrolled at our institution between June 2013 and May 2017. Consenting patients were randomized to antibiotic prophylaxis with trimethoprim-sulfamethoxazole versus no antibiotic. Patients had catheterized urine samples obtained at surgery and 6–10 days postoperatively. The primary outcome was bacteriuria and pyuria at postoperative urine collection. Secondary outcomes included symptomatic urinary tract infection and postoperative complications. Results. 70 patients consented to the study, of which 35 were randomized to receive antibiotics compared to 32 who did not. Demographics, severity of hypospadias, and type of repair were similar between the groups. Patients in the treatment group had significantly less pyuria (18%) and bacteriuria (11%) present at stent removal compared to the nontreatment group (55% and 63%; p=0.01 and p<0.001, resp.). No patient had a symptomatic urinary tract infection. There were 11 postoperative complications. Conclusions. Routine antibiotic prophylaxis appears to significantly decrease bacteriuria and pyuria in the immediate postoperative period; however, no difference was observed in symptomatic urinary tract infection or postoperative complications. Clinical Trial Registration Number NCT02593903

“Trapped in their Shame”: A Qualitative Investigation of Moral Injury in Forensic Psychiatry Patients

Individuals who engage in criminal behavior for which they are found not criminally responsible (NCR) may be at increased vulnerability to experience moral pain and, in extreme circumstances, moral injury after regaining insight into the consequences of their behavior. Yet, almost no research exists characterizing the nature, severity, or impact of moral pain in this population. Semi-structured interviews were conducted with nine forensic psychiatric patients and 21 of their care providers. Narratives were explored using thematic analysis. Findings demonstrate that NCR patients endorse symptoms consistent with moral injury, including feelings of guilt toward victims, shame for one’s behavior, and a loss of trust in one’s morality. Moral pain is a strong driver of behavior and must be understood as part of a constellation of factors influencing criminality, risk, and recovery. Future research must develop adequate tools to measure and characterize offense-related moral injury to understand its impact on this population

A Brief Measure of Fidelity for Mindfulness Programs: Development and Evaluation of the Concise Fidelity for Mindfulness-Based Interventions Tool

BackgroundMindfulness research and clinical programs are widespread, and it is important that mindfulness-based interventions are delivered with fidelity, or as intended, across settings. The MBI:TAC is a comprehensive system for assessing teacher competence, yet it can be complex to implement. A standardized, simple fidelity/engagement tool to address treatment delivery is needed.ObjectiveWe describe the development, evaluation, and outcomes of a brief, practical tool for assessing fidelity and engagement in online mindfulness-based programs. The tool contains questions about session elements such as meditation guidance and group discussion, and questions about participant engagement and technology-based barriers to engagement.MethodsThe fidelity rating tool was developed and tested in OPTIMUM, Optimizing Pain Treatment in Medical settings Using Mindfulness. The OPTIMUM study is a 3-site pragmatic randomized trial of group medical visits and adapted mindfulness-based stress reduction for primary care patients with chronic low back pain, delivered online. Two trained study personnel independently rated 26 recorded OPTIMUM sessions to determine inter-rater reliability of the Concise Fidelity for Mindfulness-Based Interventions (CoFi-MBI) tool. Trained raters also completed the CoFi-MBI for 105 sessions. Raters provided qualitative data via optional open text fields within the tool.ResultsInter-rater agreement was 77-100% for presence of key session components, and 69-88% for Likert ratings of participant engagement and challenges related to technology, with discrepancies only occurring within 2 categories: ‘very much’ and ‘quite a bit’. Key session components occurred as intended in 94-100% of the 105 sessions, and participant engagement was rated as ‘very much’ or ‘quite a bit’ in 95% of the sessions. Qualitative analysis of rater comments revealed themes related to engagement challenges and technology failures.ConclusionThe CoFi-MBI provides a practical way to assess basic adherence to online delivery of mindfulness session elements, participant engagement, and extent of technology obstacles. Optional text can guide strategies to improve engagement and reduce technology barriers

Head-group acylation of monogalactosyldiacylglycerol is a common stress response, and the acyl-galactose acyl composition varies with the plant species and applied stress

This is the peer reviewed version of the following article: Vu, H. S., Roth, M. R., Tamura, P., Samarakoon, T., Shiva, S., Honey, S., Lowe, K., Schmelz, E. A., Williams, T. D. and Welti, R. (2014), Head-group acylation of monogalactosyldiacylglycerol is a common stress response, and the acyl-galactose acyl composition varies with the plant species and applied stress. Physiol Plantarum, 150: 517–528. doi:10.1111/ppl.12132, which has been published in final form at http://doi.org/10.1111/ppl.12132. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Formation of galactose-acylated monogalactosyldiacylglycerols has been shown to be induced by leaf homogenization, mechanical wounding, avirulent bacterial infection, and thawing after snap-freezing. Here, lipidomic analysis using mass spectrometry showed that galactose-acylated monogalactosyldiacylglycerols, formed in wheat (Triticum aestivum) and tomato (Solanum lycopersicum) leaves upon wounding, have acyl-galactose profiles that differ from those of wounded Arabidopsis thaliana, indicating that different plant species accumulate different acyl-galactose components in response to the same stress. Additionally, the composition of the acyl-galactose component of Arabidopsis acMGDG depends on the stress treatment. After sub-lethal freezing treatment, acMGDG contained mainly non-oxidized fatty acids esterified to galactose, whereas mostly oxidized fatty acids accumulated on galactose after wounding or bacterial infection. Compositional data are consistent with acMGDG being formed in vivo by transacylation with fatty acids from digalactosyldiacylglycerols. Oxophytodienoic acid, an oxidized fatty acid, was more concentrated on the galactosyl ring of acylated monogalactosyldiacylglycerols than in galactolipids in general. Also, oxidized fatty acid-containing acylated monogalactosyldiacylglycerols increased cumulatively when wounded Arabidopsis leaves were wounded again. These findings suggest that, in Arabidopsis, the pool of galactose-acylated monogalactosyldiacylglycerols may serve to sequester oxidized fatty acids during stress responses
