Noch bis vor wenigen Jahren galt die interne Kommunikation in den meisten Unternehmen im Vergleich zur Kommunikation mit externen Zielgruppen als deutlich weniger anspruchsvoll oder gar als in irgendeiner Weise wettbewerbsrelevant. Wurde sie lange als reine Sozialleistung betrachtet, rückt sie nun - insbesondere vor dem Hintergrund voranschreitender Globalisierung und ihren Auswirkungen auf die Wettbewerbsfähigkeit der Unternehmen - langsam als strategisches Führungsinstrument in das Bewusstsein vieler Unternehmenslenker. Denn mehr und mehr wird deutlich, dass die eigenen Mitarbeiter ausschlaggebender Faktor bei der Bewältigung von Veränderungen sind.

BACKGROUND: Even though physician rating websites (PRWs) have been gaining in importance in both practice and research, little evidence is available on the association of patients' online ratings with the quality of care of physicians. It thus remains unclear whether patients should rely on these ratings when selecting a physician. The objective of this study was to measure the association between online ratings and structural and quality of care measures for 65 physician practices from the German Integrated Health Care Network "Quality and Efficiency" (QuE). METHODS: Online reviews from two German PRWs were included which covered a three-year period (2011 to 2013) and included 1179 and 991 ratings, respectively. Information for 65 QuE practices was obtained for the year 2012 and included 21 measures related to structural information (N = 6), process quality (N = 10), intermediate outcomes (N = 2), patient satisfaction (N = 1), and costs (N = 2). The Spearman rank coefficient of correlation was applied to measure the association between ratings and practice-related information. RESULTS: Patient satisfaction results from offline surveys and the patients per doctor ratio in a practice were shown to be significantly associated with online ratings on both PRWs. For one PRW, additional significant associations could be shown between online ratings and cost-related measures for medication, preventative examinations, and one diabetes type 2-related intermediate outcome measure. There again, results from the second PRW showed significant associations with the age of the physicians and the number of patients per practice, four process-related quality measures for diabetes type 2 and asthma, and one cost-related measure for medication. CONCLUSIONS: Several significant associations were found which varied between the PRWs. Patients interested in the satisfaction of other patients with a physician might select a physician on the basis of online ratings. Even though our results indicate associations with some diabetes and asthma measures, but not with coronary heart disease measures, there is still insufficient evidence to draw strong conclusions. The limited number of practices in our study may have weakened our findings.

Library of Congress Subject Headings (LCSH) are popular for indexing library records. We studied the possibility of assigning LCSH automatically by training classifiers for terms used frequently in a large collection of abstracts of the literature on hand and by extracting headings from those abstracts. The resulting classifiers reach an acceptable level of precision, but fail in terms of recall partly because we could only train classifiers for a small number of LCSH. Extraction, i.e., the matching of headings in the text, produces better recall but extremely low precision. We found that combining both methods leads to a significant improvement of recall and a slight improvement of F1 score with only a small decrease in precision.

The Gravitational Search Algorithm is a swarm-based optimization metaheuristic that has been successfully applied to many problems. However, to date little analytical work has been done on this topic. This paper performs a mathematical analysis of the formulae underlying the Gravitational Search Algorithm. From this analysis, it derives key properties of the algorithm's expected behavior and recommendations for parameter selection. It then confirms through empirical examination that these recommendations are sound.

The objective of this student project was for the students to develop, conduct, and supervise a training course for basic work place applications (word processing and business graphics). Students were responsible for the planning, organizing and the teaching of the course. As participants, underprivileged adolescents took part in order to learn the handling of IT applications and therefore, improve their job skills and have a better chance to get into employment. Therefore the adolescents do the role of trainees at the course. Our students worked with a population that is continually overlooked by the field. As a result, the students trained to design and implement training courses, exercised to manage projects and increased their social responsibility and awareness concerning the way of life and living conditions of other young people. The underprivileged adolescents learned to use important business applications and increased their job skills and job chances. The overall design of our concept required extensive resources to supervise and to steer the students and the adolescents. The lecturers had to teach and to counsel the students and had to be on “stand-by” just in case they were needed to solve critical situations between the two groups of young people.

Background: Immunization is the most cost-effective intervention for infectious diseases which are the major cause of morbidity and mortality worldwide. There is a scarcity of information on the vaccination status of young adults and the role of socioeconomic conditions in India. Objectives: Present study explored the adult vaccination status and influence of income and education of parents on adult vaccination status in university students from Mumbai, India. Methods: On the basis of the eligibility criterion 149 students were selected for the present study. A total of 8 vaccines namely Tdap/DTP, Varicella, MMR, Influenza, Pneumococcal, Hepatitis A, Hepatitis B and Meningococcal were included in this study for all the respondents. In addition to these vaccines, Human Papilloma Virus vaccine was also included for female respondents. Results: There were total of 149 (75 male and 74 females) respondents with the mean age of 21.5 years. The top 3 immunizations were Td/Tdap (97.3%), MMR (66.4%) and Hepatitis B (55%) among the respondents. Only 4 (5.5%) female respondents have been immunized against the HPV. Conclusions: Td/Tdap (97.3%) and MMR (66.4%) coverage was in line with the recommendations. For all the other vaccines the coverage was low varying from 5.5% to 35.4%. The vaccination coverage was better in respondents with higher educated and higher income parents. We suggest that patient education, planning by government for the implementation of policy for adult vaccination and involvement of physicians are must for better adult vaccination coverage.

The drugs we use to treat any condition – from an innocuous cough to a life-threatening cancer – are the outcome of painstaking human clinical trials. These trials are the only way to credibly determine the safety and efficacy of drugs. In recent years there has been a clear shift in clinical trial sites from core developed countries like USA, European countries to developing countries like India, China, South American countries. This shift is related to challenges and opportunities like costs of trials, recruitment issues, and regulatory challenges in developed vs. developing countries. Developing countries and developed countries have their unique disease burden patterns based on various parameters like but not limited to age, health care facilities, health insurance, sanitary conditions, environmental issues, education, nutrition and GDP. Previous studies have reported that many of the important global diseases are not much explored in clinical trials and many published clinical trials have very less international health relevance. This study was aimed at finding the correlation between disease burdens, number of clinical trials done and trial success rates. We compared 2005 - 2010 Global Burden of Disease data for Germany, India and number of clinical trials from clinicaltrials.gov database done in the same period. Our findings indicated that there was a good correlation between the disease burden and clinical trials for Germany in 2005 and 2010. For India in 2005 there was a moderate positive correlation, 2010 data showed the improvement in India in terms of match between disease burden and clinical trials. But careful observation of the data shows still a need for more trials on Communicable, maternal, neonatal and nutritional disorders.

Self-medication is of great public health importance as it often bypasses regulatory mechanisms to assure quality of health care. Nevertheless there are no established standards on how to assess self-medication. We therefore intended to systematically retrieve questionnaires and survey tools used to capture self-medication, with the aim to identify the scope of information investigated in this context and commonalities between the tools. We conducted a systematic review of the literature on questionnaires used for self-medication assessment by searching PubMed and Web of Science databases using the combinations of following keywords; self-medication, self-prescription, non-prescription, questionnaire. Truncation was used to ensure retrieval of all possible variations of search terms. The search was limited to articles published between 1st January 2000 and 31st December 2015, human studies and English language. Duplicate and irrelevant studies were excluded from the final review. A total of 158 studies were included in the review. Studies were from diverse geographical locations, most of the studies were from Nigeria 16 (10.1%) followed by India 10 (6.3%) and Iran 8 (5%). Forty-three studies (27.2%) focused on antibiotic self-medication. Majority of the studies (106; 67%) were done with adult populations. The components addressed by the questionnaires covered: reasons for self-medications in 147 (93%) studies, purchasing source in 136 (86%) studies, medical conditions to be treated in 153 (96.8%) studies, adverse events in 67 (42.4%) studies, use of prescribing information in 24 (15.1%) studies and antibiotic resistance awareness in 20 (46.5%) antibiotic studies. For 74 (46.8%) studies, survey questionnaires were self-administered and most studies (57; 36%) were done at homes of respondents. Thirty-seven (23.4%) studies did not report any recall period for self-medication practices. Study response rates varied from 17.9% to 100%, and while validity of the study questionnaire was reported for 100 (63.3%) studies, 15 (9.5%) studies reported reliability test of the study questionnaire. There is a large variety of questionnaires being used for investigating self-medication practices making comparability and meta-analyses very difficult. It is desirable to have a basic set of standardized survey questions on this topic to make available for future research groups in this field.

Das Projekt Promise2007 befasste sich mit der Erstellung und Auswertung einer Statistik zur Mitgliedersituation im Berufsverband Medizinischer Informatiker e.V.. Mit dem Ziel mehr über die Mitglieder und ihre derzeitige Situation zu erfahren wurde das Projekt an der Fachhochschule Hannover initiiert. Statistisch erfasst wurden Fragen zum Beschäftigungsverhältnis, zu Aus- und Weiterbildung, der beruflichen Situation und persönliche Angaben. Die Ergebnisse wurden ausgewertet und daraus wichtige Erkenntnisse für den BVMI e.V. abgeleitet, welche auf die weitere Verbandsarbeit Einfluss nehmen.

Daten einer umfangreichen Erhebung bei Absolventen/innen des Bachelor-Studiengangs Wirtschaftsinformatik der Hochschule Hannover eröffnen einen Einblick in das Berufsleben von Wirtschaftsinformatiker/n in den ersten Jahren nach Studienabschluss. Die Ergebnisse weisen auf eine hohe Berufszufriedenheit. Allerdings sind durchaus auch Einschränkungen der Zufriedenheit zu verzeichnen, die teilweise auf die typische Arbeitskultur in IT-Berufen zurückzuführen sind. Daneben wird das Arbeitsklima zwischen Männern und Frauen durchaus unterschiedlich wahrgenommen, auch der Wunsch nach einem ausgewogenen Verhältnis von Arbeits- und Privatleben (work/life balance) zeigt Unterschiede zwischen Männern und Frauen. Insgesamt lassen sich aus den Ergebnissen Hinweise ableiten, durch welche Maßnahmen das Studium und die Berufstätigkeiten in IT-Berufen attraktiver gestaltet werden und damit dem Fachkräftemangel entgegengewirkt werden kann.

Die Arbeit bietet einen Überblick über pflegebezogene Studiengänge und diskutiert die Akademisierung von Pflege.

Für das digitale Flugführungssystem des Versuchsflugzeugs HFB 320 wurde am Institut für Flugführung der DFVLR in Braunschweig eine Betriebsart zum automatischen zeitgenauen Fliegen im Flughafen-Nahbereich entwickelt und im Flugversuch erprobt. Der Bericht enthält die Beschreibung der eingesetzten Algorithmen zur Berechnung 4-dimensionaler Flugbahnen unter Berücksichtigung der momentanen Windsituation. Es werden verschiedene Verfahren zur Messung, Filterung und Vorhersage des Windvektors entwickelt und an Hand von Flugversuchsergebnissen diskutiert.

During the intraoperative radiograph generation process with mobile image intensifier systems (C-arm) most of the radiation exposure for patient, surgeon and operation room personal is caused by scattered radiation. The intensity and propagation of scattered radiation depend on different parameters, e.g. the intensity of the primary radiation, and the positioning of the mobile image intensifier. Exposure through scattered radiation can be minimized when all these parameters are adjusted correctly. Because radiation is potentially dangerous and could not be perceived by any human sense the current education on correct adjustment of a C-arm is designed very theoretical. This paper presents an approach of scattered radiation calculation and visualization embedded in a computer based training system for mobile image intensifier systems called virtX. With the help of this extension the virtX training system should enrich the current radiation protection training with visual and practical training aspects.

Background: Virtual reality (VR) is increasingly used as simulation technology in emergency medicine education and training, in particular for training nontechnical skills. Experimental studies comparing teaching and learning in VR with traditional training media often demonstrate the equivalence or even superiority regarding particular variables of learning or training effectiveness. Objective: In the EPICSAVE (Enhanced Paramedic Vocational Training with Serious Games and Virtual Environments) project, a highly immersive room-scaled multi-user 3-dimensional VR simulation environment was developed. In this feasibility study, we wanted to gain initial insights into the training effectiveness and media use factors influencing learning and training in VR. Methods: The virtual emergency scenario was anaphylaxis grade III with shock, swelling of the upper and lower respiratory tract, as well as skin symptoms in a 5-year-old girl (virtual patient) visiting an indoor family amusement park with her grandfather (virtual agent). A cross-sectional, one-group pretest and posttest design was used to evaluate the training effectiveness and quality of the training execution. The sample included 18 active emergency physicians. Results: The 18 participants rated the VR simulation training positive in terms of training effectiveness and quality of the training execution. A strong, significant correlation (r=.53, P=.01) between experiencing presence and assessing training effectiveness was observed. Perceived limitations in usability and a relatively high extraneous cognitive load reduced this positive effect. Conclusions: The training within the virtual simulation environment was rated as an effective educational approach. Specific media use factors appear to modulate training effectiveness (ie, improvement through “experience of presence” or reduction through perceived limitations in usability). These factors should be specific targets in the further development of this VR simulation training.

Sustainable tourism is a niche market that has been growing in recent years. At the same time, companies in the mass tourism market have increasingly marketed themselves with a “green” image, although this market is not sustainable. In order to successfully market sustainability, targeted marketing tactics are needed. The aim of this research is to establish appropriate marketing tactics for sustainable tourism in the niche market and in the mass market. The purpose is to uncover current marketing tactics for both the mass tourism market and the sustainable tourism niche market. It also intends to explore how consumers who are more interested in sustainability differ from consumers with less interest in sustainability in terms of their perception of sustainability in tourism. Furthermore, this research paper will assess the trustworthiness of sustainable travel offers and the trustworthiness of quality seals in sustainable tourism. For this purpose, an online survey was conducted, which was addressed at German-speaking consumers. The survey showed, that consumers with more general interest in sustainability also consider sustainability to be more relevant in tourism. Offers for sustainable travel and quality seals were perceived as not very trustworthy. Moreover, no link could be found between the interest in sustainability and the perception of trustworthiness. On the basis of the above, it is advisable to directly advertise sustainability in the niche market and to mention sustainability in the mass market only as an accompaniment or not at all. Further research could be undertaken to identify which factors influence the trustworthiness of offers, and trustworthiness of quality seals in sustainable tourism.

Die in den Betrieben häufig mit hohem gerätetechnischen und organisatorischem Aufwand installierten EDV-gestützten Informationssysteme zur Planung und Steuerung des Fertigungsprozesses genügen im allgemeinen nicht den an sie gestellten Anforderungen. Die Gründe dafür liegen in der Hauptsache in einem falschen Modellansatz und der mangelnden Datenqualität der eingesetzten Daten, verbunden mit einer unzureichenden Rückkopplung zwischen Vorgabe und Rückmeldung. Hinzu kommen das Fehlen geeigneter Aussagen (Kenngrößen) zur gezielten Beeinflussung des Prozesses und Akzeptanzprobleme der Mitarbeiter beim Umgang mit der EDV. Die genannten Schwachstellen geben die Richtung der Zielsetzung dieser Arbeit vor. Dieses Ziel bestand zunächst darin, eine Methode zu entwickeln, mit der die Anforderungen an die in einem Industriebetrieb zur Planung, Steuerung und Überwachung verwendeten Daten zu formulieren sind, um dann eine anforderungsgerechte Abstimmung dieser Daten im betrieblichen Datenfluß im Sinne eines kybernetischen Regelkreises vorzunehmen und Aussagen über die betrieblichen Zielgrößen zu erhalten. Aus der Vielzahl betrieblicher Vorgänge und Funktionsbereiche wurde der Fertigungsprozeß bei der Werkstättenfertigung im Produktionsbetrieb deshalb ausgewählt, weil hier in der Praxis wegen der Komplexität der Abläufe die höchsten Anforderungen an die Daten gestellt werden und deshalb auch die meisten Probleme bei der Erfüllung dieser Anforderungen auftreten. Außerdem ist die Fertigung nach dem Werkstättenprinzip am häufigsten in der Praxis anzutreffen. Als erstes war es nötig, die zeitlichen, quantitativen und qualitativen Anforderungen an die Daten aus einer Vielzahl durchgeführter Schwachstellenanalysen herauszuarbeiten und zu definieren. Die nächste Aufgabe bestand darin, die Einflußgrößen auf die Datenanforderungen, hier unterteilt in innere (datumsbezogene) und äußere (prozeßbezogene) zu bestimmen und in ihren Auswirkungen zu untersuchen. Die Betrachtung der Einflußgrößen ergab, daß die Aufgabe und die Verwendung des Datums im Prozeß für die Ermittlung der Anforderungen exakt bestimmt werden müssen. Aus diesem Grund war der Prozeß primär- und sekundärseitig in Abhängigkeit der Aufgabenstellung ausführlich zu beschreiben. Die Einflüsse der Aufbauorganisation waren ebenso wie die der Ablauforganisation zu berücksichtigen, darunter fielen auch die Auswirkungen der Automatisierungsansätze, z.B. durch den Einsatz flexibler Fertigungssysteme im Primärprozeß. Der Ansatz, von dem hier ausgegangen wurde, baut sich deshalb im ersten Schritt der vorgeschlagenen Vorgehensweise auf dem Modell eines Produktionssystems auf, das aus den Erkenntnissen von in mehreren Firmen durchgeführten Prozeßanalysen entwickelt wurde. In diesem Modell ist der Datenfluß und organisatorische Ablauf im Fertigungsprozeß in Matrixform festgehalten. Für jedes einzelne Prozeßdatum sind in der Matrix, bezogen auf die Aufgabenstellung, detailliert die Verwendungs- und Verflechtungsbeziehungen aufgezeichnet. Im zweiten Schritt erfolgt auf der Grundlage dieses Modells eine bedarfsgerechte Prozeßdatenauswahl. Die zeitliche Struktur des Datenflusses im Prozeß wird in Schritt drei mit Hilfe eines Ereignis-Zeitgraphens dargestellt. Die eigentliche zeitliche, quantitative und qualitative Anforderungsermittlung findet im vierten und gleichzeitig letzten Schritt anhand einer dafür entworfenen Datenanforderungsliste statt. Die Ergebnisse dieser anforderungsgerechten Datenanalyse nach der hier entwikkelten Systematik können in vielerlei Hinsicht Verwendung finden. Im Hinblick auf die eingangs genannten Problemstellungen sind beispielsweise folgende Einsatzmöglichkeiten denkbar und an Beispielen im einzelnen erläutert. - Verbesserung der Datenqualität - Rückkopplung im Sinne des kybernetischen Regelkreismodells - Bilden von Prozeßkenngrößen - Transparenz der EDV-Prozeßabläufe

Logistische Funktionsketten mit der Integration von Information, Arbeits- und Materialflüssen für einen durchgängigen Auftragsabwicklungsprozeß müssen auch Qualitätssicherungsfunktionen mit beinhalten. Dies ist nur über eine entsprechende QS-Systemarchitektur zu realisieren, die an jeder Stelle im dispositiven und operativen Ablauf im Sinne der Fehlervermeidung dafür sorgt, daß die angestrebten Qualitätsziele erreicht werden.

Wissensmanagement (knowledge management) ist ein aktuelles Thema in Theorie und Praxis vieler verschiedener Fachgebiete. Sowohl Wirtschaftsinformatik, Organisationslehre, Kommunikationswissenschaften als auch Soziologie und Erkenntnistheorie setzen sich mit Fragen auseinander, die sich mit dem Verständnis von Wissensprozessen und mit der Handhabung von Wissen beschäftigen. Viele Branchen und Wirtschaftsbereiche werden dabei aufgegriffen, so wird beispielsweise die Handhabung von Wissen in multinationalen, verteilten Unternehmen und Allianzen, die Kreation und Weitergabe von Wissen in Innovationsprozessen und nicht zuletzt die Handhabung von Wissen in Beratungsunternehmen wie Steuerkanzleien, Unternehmensberatungen und auch Anwaltsbüros diskutiert. Mit Wissen sollte in Unternehmen nicht beiläufig und zufällig umgegangen werden, sondern bewusst, zielgerichtet, systematisch und methodisch. Dies gilt besonders für Anwälte, deren Beruf und Berufsausübung durch mehrere aktuelle Entwicklungen geprägt sind. Der Umgang mit dem Wissen der Mitarbeiter und der Kanzlei gewinnt durch einige Entwicklungen unmittelbar Bedeutung.

The antimicrobial activity of a phagemixture and a lactic acid bacteriumagainst Staphylococcus aureus isolates from bovine origin was investigated in vitro with regard to possible applications in the therapy of udder inflammation (mastitis) caused by bacterial infections. The S. aureus isolates used for inoculation derived from quarter foremilk samples of mastitis cases. For the examination of the antimicrobial activity, the reduction of the S. aureus germ density was determined [log10 cfu/mL]. The phage mixture consisted of the three obligatory lytic and S. aureus-specific phages STA1.ST29, EB1.ST11 and EB1.ST27 (1:1:1). The selected Lactobacillus plantarum strain with proven antimicrobial properties and the phage mixture were tested against S. aureus in milk, both alone and in combination. The application of the lactic acid bacterium showed only a low reduction ability for a 24 h incubation period. The bacteriophage mixture as well as its combination with the lactic acid bacterium showed high antimicrobial activity against S. aureus for a 24 h incubation period at 37 C, with only the phage mixture showing significance.

In this article, we present the software architecture of a new generation of advisory systems using Intelligent Agent and Semantic Web technologies. Multi-agent systems provide a well-suited paradigm to implement negotiation processes in a consultancy situation. Software agents act as clients and advisors, using their knowledge to assist human users. In the presented architecture, the domain knowledge is modeled semantically by means of XML-based ontology languages such as OWL. Using an inference engine, the agents reason, based on their knowledge to make decisions or proposals. The agent knowledge consists of different types of data: on the one hand, private data, which has to be protected against unauthorized access; and on the other hand, publicly accessible knowledge spread over different Web sites. As in a real consultancy, an agent only reveals sensitive private data, if they are indispensable for finding a solution. In addition, depending on the actual consultancy situation, each agent dynamically expands its knowledge base by accessing OWL knowledge sources from the Internet. Due to the standardization of OWL, knowledge models easily can be shared and accessed via the Internet. The usefulness of our approach is proved by the implementation of an advisory system in the Semantic E-learning Agent (SEA) project, whose objective is to develop virtual student advisers that render support to university students in order to successfully organize and perform their studies.

Untersuchungen zu Berufen der Wirtschaftsinformatik bleiben weiterhin interessant, wenn sie helfen können, dem mittlerweile länger anhaltenden IT-Fachkräftemangel entgegenzuwirken. Eine Untersuchung der Hochschule Hannover zu Wirtschaftsinformatikern/-informatikerinnen in den ersten zehn Jahren im Beruf zeigt deren berufliche Ziele und die berufliche Zufriedenheit, die sie erlangen. Deutlich wird, dass Frauen und Männer das Arbeitsklima und die Arbeitsbedingungen sehr unterschiedlich wahrnehmen und daher auch unterschiedlich zufrieden sind. Dabei bemängeln Frauen vor allem Merkmale, die mit „fehlender Fairness“ zu beschreiben sind.
