Mastering ERP Interface Complexity - A Scalable User Interface Concept for ERP Systems

In recent literature, numerous research efforts addressed the usability of enterprise resource planning (ERP) systems. Although several heuristics, surveys and interviews provided valuable results to understand and improve the user satisfaction of ERP, explicit research on the user interface design has been rarely discussed. As ERP systems have a high dissemination in many enterprise areas, usability issues located in the user interface have a significant impact on millions of users. This paper gives an overview of the related work in the fields of usability studies, complexity reduction strategies and visual information presentation in ERP systems. The conclusion reveals a niche currently not considered in research. Therefore, an abstract interface model is introduced that aims to establish a new understanding of accessing ERP systems. The scalable user interface concept attempts to reduce the problem of user guidance and overall system complexity to ease the user’s system access.
A monoclonal antibody (MUM1p) detects expression of the MUM1/IRF4 protein in a subset of germinal center B cells, plasma cells, and activated T cells.

A new monoclonal antibody (MUM1p) was used to study the cell/tissue expression of human MUM1/IRF4 protein, the product of the homologous gene involved in the myeloma-associated t(6;14) (p25;q32). MUM1 was expressed in the nuclei and cytoplasm of plasma cells and a small percentage of germinal center (GC) B cells mainly located in the "light zone. " Its morphologic spectrum ranged from that of centrocyte to that of a plasmablast/plasma cell, and it displayed a phenotype (MUM1(+)/Bcl-6(-)/Ki67(-)) different from that of most GC B cells (MUM1(-)/Bcl-6(+)/Ki67(+)) and mantle B cells (MUM1(-)/Bcl-6(-)/Ki67(-)). Polymerase chain reaction (PCR) analysis of single MUM1(+ )cells isolated from GCs showed that they contained rearranged Ig heavy chain genes with a varying number of V(H) somatic mutations. These findings suggest that these cells may represent surviving centrocytes and their progeny committed to exit GC and to differentiate into plasma cells. MUM1 was strongly expressed in lymphoplasmacytoid lymphoma, multiple myeloma, and approximately 75% of diffuse large B-cell lymphomas (DLCL-B). Unlike normal GC B cells, in which the expression of MUM1 and Bcl-6 were mutually exclusive, tumor cells in approximately 50% of MUM1(+) DLCL-B coexpressed MUM1 and Bcl-6, suggesting that expression of these proteins may be deregulated. In keeping with their proposed origin from GC B cells, Hodgkin and Reed-Sternberg cells of Hodgkin's disease consistently expressed MUM1. MUM1 was detected in normal and neoplastic activated T cells, and its expression usually paralleled that of CD30. These results suggest that MUM1 is involved in the late stages of B-cell differentiation and in T-cell activation and is deregulated in DLCL-B. (Blood. 2000;95:2084-2092)
Economic valuation of phenotypic cattle trait preferences in trypanosomosis prevalent production systems of Eastern Africa : implications for sustainable cattle breeding programs

The study examines cattle keeping households preferences for phenotypic cattle traits in trypanosomosis prevalent production systems of Kenya and Ethiopia, using cross-sectional choice experiment survey data of 508 households. The data was collected between September 2004 and May 2005. Further, it investigates potentially sustainable pathways by which the households can access improved cattle breeds based on their traits of preferences. Mixed logit model has been employed to investigate existence of preference heterogeneity, while a latent class model is used to investigate the sources of heterogeneity and presence of endogenous preference segmentation for cattle traits amongst the cattle keeping households. The results reveal significant preference heterogeneity among the households based on the cattle production systems. Highly valued traits for the cropping systems include traction fitness and trypanotolerance, while traits associated with herd increase are considered important in pastoral systems. Considering heterogeneity within population segments provides a framework for adapting breeding policy interventions to specific producer segments, by integrating preferred traits in a breed improvement program. Additional results indicate that communal breeding initiatives provide important pathways through which resource-poor cattle keepers can access improved livestock breeds. Factors that influence a households willingness to participate in such a collective action decision are analyzed using a binary logit model.
Hypermethylation of selected genes in endometrial carcinogenesis.

OBJECTIVES Endometrial cancer is one of the most common malignancies in women. The prevention has failed so far to develop an effective screening program and its incidence is rising in proportion to the incidence of cervical cancer. In recent years the investigation of malignancy genomics (genetic and epigenetic changes) has become the main focus of scientists because of its high sensitivity and specificity. MATERIAL AND METHODS We conducted a prospective longitudinal study at the Dpt. of Gynaecology and Obstetrics of the Jessenius Faculty of Medicine in Martin from 2010 to 2012, in collaboration with the Institute of Pathology of the University Hospital in Martin. We analysed paraffin blocks of endometrial tissue from 123 women with endometrial cancer, hyperplasia and normal endometrial findings. By the use of bisulphidic modification technique and nested methylation-specific PCR (MSP), we analysed the methylation patterns of three genes: GSTP1, E-cad, RASSF1. RESULTS We found a statistically significant increase of methylation of the RASSF1 gene in endometrial cancer compared to simplex hyperplasia and intact endometrial tissue (p<0.001). GSTP1 and E-cad did not show any relevant methylation pattern in various endometrial lesions. CONCLUSION According to the results of our study, RASSF1 gene methylation could serve as a prognostic factor of endometrial carcinogenesis and could help to predict the behaviour of endometrial hyperplasia.

Intraocular Pressure: Goldmann Tonometry, Computational Model, and Calibration Equation

Purpose:There exists a concern about the general accuracy of intraocular pressure (IOP) measurements using tonometry, and especially Goldmann applanation tonometer (GAT) because it considers the cornea as an infinite thin shell. In this study, the relationship between the true IOP and tonometric IOP, external curvature radius (ECR), and central corneal thickness (CCT) is explored. Methods:In this study, the calibration of the IOP measurements through GAT for different values of CCT, ECR, and E (Young modulus), is done through computational simulations of the mechanical behavior of the cornea subjected to the applanation process using the finite element method (FEM). Previous to this simulations, experimentations on rabbits were performed to confirm that inaccurate readings are obtained with GAT in certain conditions. This methodology is also followed to establish the range of corneal parameters of patients for which the GAT measure of pressure is reliable. The calibration equation for GAT measurements is developed from a statistical multiple linear regression analysis. Results:Based on a statistical variable analysis of the computational modeling results, a calibration equation is established for the GAT that relates the true IOP with the ECR, CCT, and GAT measurements. Conclusions:Our results show that GAT measures are linearly dependent on the modulus of elasticity of the cornea; nevertheless, if we consider a healthy cornea with a specific modulus of elasticity, it is possible to correct the measure with a linear equation involving CCT and ECR.
The Parahippocampal Gyrus in Alzheimer's Disease: Clinical and Preclinical Neuroanatomical Correlates

Abstract: The human parahippocampal gyrus forms a large part of the limbic lobe along the ventromedial part of the temporal cortical mantle. It is a variable and complicated cortex in terms of structure, and the latter is aggravated further by interfaces with the anterior insula anteriorly and the cingulate gyrus and occipital lobe posteriorly. Additional complications relate to its lateral border with the temporal cortex and especially the sulcal configurations that define this junction. The rhinal sulcus, which separates parahippocampal and temporal cortices in other species, including the anthropoid apes, is either lacking or rudimentary in the human brain. Thus, defining this junction requires cytoarchitectural examination and precludes the use of mere inspection of sulcal existing patterns. The cortical areas that form the parahippocampal gyrus are vulnerable to pathological changes in Alzheimer's disease (AD), and its entorhinal and perirhinal subdivisions are both the most heavily damaged cortical areas and the focus for disease onset. The neurons that acquire neurofibrillary tangles (NFTs) occupy the junction of the isocortical mantle with the limbic cortical mantle, but share, or partially share, a vulnerability phenotype with large neurons in both domains. The differential expression of this phenotype across time creates the false impression of NFT spread in cross‐sectional comparisons of AD brains. The questions of what this phenotype is and why it is expressed first in the perirhinal and entorhinal cortices of the parahippocampal gyrus are the central molecular biological/neuroanatomical questions in understanding the etiology of AD.
Activation of the complement system in the adult respiratory distress syndrome.

The adult respiratory distress syndrome (ARDS) is an acute pulmonary disorder characterized by the accumulation of neutrophils within the lower respiratory tract. Because activation of the complement system can generate C5a, a potent neutrophil chemoattractant, complement activation was assessed in both serum and bronchoalveolar lavage fluid obtained from 10 patients with ARDS and compared with that from normal control subjects. Crossed immunoelectrophoresis was used to determine activation of the complement components C3 and properdin factor B (PFB), and radioimmunoassay was used to determine the presence of C5a. Complement activation was not detected either in the plasma or in the lung epithelial lining fluid of the control subjects. In contrast, evidence of C3 activation was found in the plasma of 50% of the patients with ARDS when initially studied; likewise, C3 activation, PFB activation, and C5a could all be detected in the epithelial lining fluid of all patients with ARDS with a single exception. Follow-up bronchoalveolar lavages revealed decreased amounts of C3 activation and C5a 2 to 7 days after the onset of ARDS, and the complement activation had resolved when the patients with ARDS had completely recovered. To determine if the C5a in bronchoalveolar lavage fluid could be responsible for the influx of neutrophils observed in ARDS, epithelial lining fluids obtained from both normal control subjects and from patients with ARDS were fractionated by molecular sieve chromatography. Two distinct fractions of chemotactic activity were found in the ARDS bronchoalveolar lavage fluid. (ABSTRACT TRUNCATED AT 250 WORDS)
Study design issues in evaluating immune biomarkers

Purpose of reviewThe dramatic increase in the number and type of immune biomarkers that can be measured, particularly those assessing immune activation, has led to numerous investigations in HIV-infected individuals to explore pathogenesis and to assess therapeutic interventions that aim to attenuate immune activation. An overview is provided on study designs and related statistical and operational issues relevant to these investigations. Recent findingsCohort studies and nested case–control studies within these cohorts have identified multiple biomarkers that are associated with an increased risk of disease. Early-stage clinical trials of therapies to address these risks in HIV-infected individuals with viral suppression on antiretroviral therapy are a substantial focus of current HIV research. SummaryAppropriate study design is essential in biomarker research.
The effect of recombinant human granulocyte-macrophage colony-stimulating factor on neutropenia and related morbidity in chronic severe neutropenia.

STUDY OBJECTIVE To define the clinical and hematologic effects of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on patients with chronic severe neutropenia. DESIGN Open-label, phase II study of rhGM-CSF. SETTING Inpatient hematology and surgery clinic at a university medical center. PATIENTS Four consecutive patients with chronic severe neutropenia, which in two cases was complicated by severe infection, in one case by perianal fistula, and in one case by complete rectal prolapse. Two patients had chronic idiopathic neutropenia; one patient had congenital neutropenia (myelokathexis); and one patient had autoimmune neutropenia. INTERVENTIONS The rhGM-CSF was given intravenously or subcutaneously at starting dosages of 150 to 1000 micrograms/m2 body surface area.d for 12 to 14 consecutive days. Two patients received a second course of daily rhGM-CSF treatment after a nontreatment interval of 14 to 20 days. MEASUREMENTS AND MAIN RESULTS In all four patients, the absolute neutrophil counts increased from less than 0.25 x 10(9)/L to 3.2 to 19.2 x 10(9)/L within 2 weeks of beginning rhGM-CSF therapy. Two patients had life-threatening infections that resolved during therapy. The two other patients had major ano-rectal surgery during rhGM-CSF treatment and had no postoperative infections. CONCLUSIONS In patients with chronic neutropenia, rhGM-CSF may increase neutrophil counts. This therapy may be a useful adjunct to antibiotic therapy for patients with infection and perioperatively for patients having anorectal surgery.
Professionalism and Ethics Education on Relationships and Boundaries: Psychiatric Residents’ Training Preferences

ObjectiveAwareness of the privileges and limits of one’s role as physician, as well as recognition and respect for the patient as a human being, are central to ethical medical practice. The authors were particularly interested in examining the attitudes and perceived needs of psychiatric residents toward education on professional boundaries and relationships given the heightened current focus on professionalism and ethics.MethodsResidents from six psychiatric residencies provided views on professionalism and ethics education on a survey encompassing 10 domains of professionalism. The authors focus on residents’ perceived need for education on boundaries in the psychiatrist-patient relationship and in peer-peer and supervisor-trainee interactions.ResultsRespondents (N = 134) felt that nine relationship and boundary issues arising during training should receive more education: being asked to work with inadequate supervision, resolving conflicts between attendings and trainees, resident health care, adequately caring for patients while adhering to work-hour guidelines, performing work beyond one’s competence, mistreatment of residents, sexual/romantic relationships between faculty and trainees, mistreatment of medical students, and sexual/romantic relationships between residents and medical students (p>0.05 in all cases). In addition, 15 relationship and boundary issues arising during clinical practice were felt to warrant more education: responding to impaired colleagues, coping with mistakes in clinical care, reporting mistakes, balancing personal and professional life, resolving conflicts, writing prescriptions for friends or family, allocation of health care resources, providing medical advice to friends and family, physicians’ social responsibilities, interacting with families, medicine as a profession, gender bias, being asked to falsify clinical information, accepting gifts from patients, and personal relationships with patients (p>0.05 in all cases). ConclusionThe authors found a perceived need for more education for psychiatric residents for the majority of topics pertaining to boundaries and relationships. Residents who reported encountering ethical dilemmas more frequently wanted more education on these topics.
Pathways to Prison

This study examines ways in which victimization may contribute to criminal involvement among incarcerated women. The authors conduct interviews with 60 women in a maximum-security prison to gather each woman's perspective on psychological, physical, and sexual victimization in her life. Qualitative analyses indicate ways that victimization relates directly to women's crimes as well as influences health, psychosocial functioning, or systemic involvement to create difficult situations with which the women struggle. Case histories are used to illustrate pervasive impacts of victimization, and the roles of multiple traumas and cumulative impact are discussed.
Quantitative assessment of localization and colocalization of glutamate, aspartate, glycine, and GABA immunoreactivity in the chick retina

We examined the posthatch chick retina for the frequency of occurrence of localization and colocalization of four amino acid transmitter candidates: glutamate (Glu), aspartate (Asp), gamma aminobutyric acid (GABA), and glycine (Gly) using postembedding methods. We support previous studies of Glu, Asp, GABA, and Gly localization in the direct and indirect functional pathways of the chick retina and extend these studies with new qualitative and quantitative observations. We found that photoreceptors show distinct cellular immunoreactivity for both Glu (Glu+) and Asp+, but not for Gly (Gly−) or GABA. Moreover, there is compartmentalization of Glu and Asp staining within the photoreceptors. All horizontal cells react strongly with Asp and Glu, about three‐fourths are GABA+ and three‐fourths of these are Gly+. Bipolar cells are uniformly Glu+, heterogeneously Asp+, occasionally Gly+, but GABA−. A majority of amacrine cells stain heterogeneously with all antibodies: 90% are Gly+, slightly more than half colocalize Glu, GABA, and Gly. Furthermore, amacrine cells in the outer two or three rows of cells are more likely to be stained by Gly than Glu, Asp, or GABA. Confirming previous studies, ganglion cells were mostly immunoreactive for Glu and Asp with fewer reactive for GABA and Gly. Stong and distinctly cellular immunoreactivity was found in both central and peripheral retina. Our findings show: 1) there is extensive colocalization of Glu, Asp, GABA, and Gly among most retinal neurons, including some cells that contain all four; 2) cells of the direct functional pathway tend to be labeled by Glu and Asp generally to the exclusion of GABA and Gly, while those of the indirect pathway tend to be labeled by GABA+ and/or Gly+ in addition to Glu+ and Asp+; 3) different cell body layers have distinct patterns of colocalization; and 4) there is no qualitative difference in staining patterns between peripheral and central retina.

A New High-Temperature Ultrasonic Transducer for Continuous Inspection

A novel design of piezoelectric ultrasonic transducer is introduced, suitable for operation at temperatures of up to 700 °C-800 °C. Lithium niobate single crystal is chosen as the piezoelectric element primarily due to the high Curie temperature of 1200 °C. A backing element based on a porous ceramic is designed for which the pore volume fraction and average pore diameter in the ceramic matrix can be controlled in the manufacturing process; this enables the acoustic impedance and attenuation to be selected to match their optimal values as predicted by a one-dimensional transducer model of the entire transducer. Porous zirconia is selected as the ceramic matrix material of the backing element to obtain an ultrasonic signal with center frequency of 2.7-3 MHz, and 3-dB bandwidth of 90%-95% at the targeted operating temperature. Acoustic coupling of the piezocrystal to the backing element and matching layer is investigated using commercially available high-temperature adhesives and brazing alloys. The performance of the transducer as a function of temperature is studied. Stable bonding and clear signals were obtained using an aluminum brazing alloy as the bonding agent.
Ncf1-Associated Reduced Oxidative Burst Promotes IL-33R+ T Cell-Mediated Adjuvant-Free Arthritis in Mice12

Reactive oxygen species (ROS) are important in the immune defense against invading pathogens, but they are also key molecules in the regulation of inflammatory reactions. Low levels of ROS production due to a polymorphism in the neutrophil cytosolic factor 1 (Ncf1) gene are associated with autoimmunity and arthritis severity in mouse models induced with adjuvant. We established an adjuvant-free arthritis model in which disease is induced by injection of the autoantigen collagen type II (CII) and depends on IL-5-producing T cells and eosinophils. In addition, the transgenic expression of mutated mouse CII allowed us to investigate an autoreactive immune response to an autologous Ag and by that natural tolerance mechanism. We show that a deficient ROS production, due to a spontaneous mutation in Ncf1, leads to increased autoantibody production and expansion of IL-33R-expressing T cells, impaired T cell tolerance toward tissue-specific CII, and severe arthritis in this unique model without disturbing adjuvant effects. These results demonstrate that the insufficient production of ROS promotes the breakdown of immune tolerance and development of autoimmune and adjuvant-free arthritis through an IL-5- and IL33R-dependent T cell activation pathway.
SMAD expression in the testis: An insight into BMP regulation of spermatogenesis

Bone morphogenetic proteins (BMPs), members of the transforming growth factor‐β superfamily, extensively influence events that establish male fertility, affecting germ cells and somatic cells throughout fetal and postnatal life. BMP signals are relayed by SMAD proteins, transcription factors that translocate to the nucleus upon ligand stimulation. We show that BMP signaling in the testis may be regulated by selective expression of BMP‐responsive and inhibitory SMADs, with expression differing between the first wave and adult spermatogenesis. Smad1, Smad5, Smad8, Smad4, Smad6, and Smad7 expression is ubiquitous during testis development but becomes cell‐specific in the adult. Furthermore, regulated SMAD6 protein expression at the onset of spermatogenesis suggests differential responsiveness of spermatogonial subpopulations to ligands. In vitro, immature Sertoli cells and spermatogonia transduce BMP2 and BMP4 signals by means of SMAD1, SMAD5, and SMAD8. Based on these findings, we extrapolate these data to interpret BMP mutant testis phenotypes in terms of SMAD availability for signal transduction.
