Der vorliegende Artikel beschreibt die Ergebnisse einer Studie zur Sicherheit von Web-Servern niedersächsischer Unternehmen aus dem Raum Hannover. Untersucht wurden vier Unternehmensgruppen, die sich aus Mitgliedern von Unternehmensverbänden und berufsständischen Körperschaften zusammensetzen. Insgesamt werden mehr als 1800 Unternehmen betrachtet. Als Indikator für die IT-Sicherheit wurden vier Sicherheitslücken herangezogen, die leicht überprüft werden können, ohne die Web-Server in ihrem Betrieb zu beeinträchtigen. Die Ergebnisse sind ernüchternd: Viele Unternehmen setzen keine Verschlüsselung ein oder die Web-Server-Software ist nicht auf dem neusten Stand. Bei ungefähr jedem dritten Unternehmen, welches Verschlüsselung einsetzt, enthält die Software seit mehr als einem Jahr bekannte Schwachstellen und sollte umgehend aktualisiert werden. Dies zeigt, dass das IT-Sicherheitsmanagement in vielen Unternehmen mangelhaft ist.

Eine wertorientierte Unternehmensführung hat in den letzten Jahren in den Unternehmen zunehmend an Bedeutung gewonnen. Wertorientierung stellt dabei ein Führungsverhalten dar, welches sich mit der Gestaltung und Realisierung von wertorientierten Zielen auf Managementebene beschäftigt. Heutzutage lebt Wertorientierung vom Einklang aus ökonomischen, ökologischen und gesellschaftlichen Gesichtspunkten. Die vorliegende Masterarbeit befasst sich mit der Geschäftsberichtsanalyse der DAX-30-Unternehmen hinsichtlich wertorientierter Steuerung. Dabei werden Unternehmen hinsichtlich ihres Bekenntnisses zur Wertorientierung, Veröffentlichung wertorientierter Kennzahlen und Höhe der Kapitalkostensätze untersucht.Hierbei kommt der Vergleichbarkeit und Transparenz eine entscheidende Rolle zu. Die Untersuchung ergibt ein hohes Bekenntnis zur Wertorientierung in nahezu allen betrachteten DAX-Unternehmen. Die Unternehmen führen viele Spitzenkennzahlen an, die vorwiegend auf dem Economic Value Added basieren. Zusätzlich werden eine Reihe weiterer, in der betrieblichen Praxis als wertorientierte Kennzahlen genutzte Messgrößen, herausgegeben. Eine Vergleichbarkeit untereinander gestaltet sich sehr schwierig, da Berechnung und Bezeichnung gleicher Kennzahlen sehr unterschiedlich sind. Daran wird sich ohne einheitlichen Standard in naher bis mittelfristiger Zukunft nichts ändern.

Ein Autobewerter für von Studierenden eingereichte Programme führt die im ProFormA-Aufgabenformat sequentiell spezifizierten "Tests" aus, um die Einreichung zu prüfen. Bzgl. der Interpretation und Darstellung der Testausführungsergebnisse gibt es derzeit keinen graderübergreifenden Standard. Wir beschreiben eine Erweiterung des ProFormA-Aufgabenformats um eine Hierarchie von Bewertungsaspekten, die nach didaktischen Aspekten gruppiert ist und Referenzen auf die Testausführungen besitzt. Die Erweiterung wurde in Graja umgesetzt, einem Autobewerter für Java-Programme. Je nach gewünschter Detailaufschlüsselung der Bewertungsaspekte müssen in der Konsequenz Testausführungen in Teilausführungen aufgebrochen werden. Wir illustrieren unseren Vorschlag unter Einsatz der Testwerkzeuge Compiler, dynamischer Softwaretest, statische Analyse sowie unter Einsatz menschlicher Bewerter.

Angesichts der tiefgreifenden Veränderungen in der Medienbranche (z. B. Digitalisierung, Konvergenz) müssen Medienunternehmen gemeinsam mit externen Partnern innovative Geschäftsmodelle vorantreiben. Die vorliegende Arbeit untersucht die Bedeutung der Beziehungsqualität und der Nutzung von Steuerungsmechanismen für den Erfolg unternehmensübergreifender Geschäftsmodellinnovationen. Anhand eines Datensatzes von 198 Medienunternehmen weisen wir einen positiven Zusammenhang zwischen der Beziehungsintensität und der Umsetzung von Geschäftsmodellinnovationen nach. Dieser Zusammenhang wird durch ein starkes Vertrauen und detaillierte formelle Verträge zwischen den Partnern zusätzlich gefördert. Daraus lässt sich ableiten, wie Medienunternehmen Partnerschaften im Kontext von Business-Model-Innovationen effektiv gestalten können.

Metagenomic studies use high-throughput sequence data to investigate microbial communities in situ. However, considerable challenges remain in the analysis of these data, particularly with regard to speed and reliable analysis of microbial species as opposed to higher level taxa such as phyla. We here present Genometa, a computationally undemanding graphical user interface program that enables identification of bacterial species and gene content from datasets generated by inexpensive high-throughput short read sequencing technologies. Our approach was first verified on two simulated metagenomic short read datasets, detecting 100% and 94% of the bacterial species included with few false positives or false negatives. Subsequent comparative benchmarking analysis against three popular metagenomic algorithms on an Illumina human gut dataset revealed Genometa to attribute the most reads to bacteria at species level (i.e. including all strains of that species) and demonstrate similar or better accuracy than the other programs. Lastly, speed was demonstrated to be many times that of BLAST due to the use of modern short read aligners. Our method is highly accurate if bacteria in the sample are represented by genomes in the reference sequence but cannot find species absent from the reference. This method is one of the most user-friendly and resource efficient approaches and is thus feasible for rapidly analysing millions of short reads on a personal computer.

Of late, decrease in mineral oil supplies has stimulated research on use of biomass as an alternative energy source. Climate change has brought problems such as increased drought and erratic rains. This, together with a rise in land degeneration problems with concomitant loss in soil fertility has inspired the scientific world to look for alternative bio-energy species. Euphorbia tirucalli L., a tree with C3/CAM metabolism in leaves/stem, can be cultivated on marginal, arid land and could be a good alternative source of biofuel. We analyzed a broad variety of E. tirucalli plants collected from different countries for their genetic diversity using AFLP. Physiological responses to induced drought stress were determined in a number of genotypes by monitoring growth parameters and influence on photosynthesis. For future breeding of economically interesting genotypes, rubber content and biogas production were quantified. Cluster analysis shows that the studied genotypes are divided into two groups, African and mostly non-African genotypes. Different genotypes respond significantly different to various levels of water. Malate measurement indicates that there is induction of CAM in leaves following drought stress. Rubber content varies strongly between genotypes. An investigation of the biogas production capacities of six E. tirucalli genotypes reveals biogas yields higher than from rapeseed but lower than maize silage.

Purpose. To identify stroke survivors with symptoms of poststroke depression and the extent of psychiatry needs and care they have received while on physiotherapy rehabilitation. Participants. Fifty stroke survivors (22 females and 28 males) at the outpatient unit of Physiotherapy Department, University of Nigeria Teaching Hospital, Enugu, who gave their informed consent, were randomly selected. Their age range and mean age were 26–66 years and 54.76 ± 8.79 years, respectively. Method. A multiple case study of 50 stroke survivors for symptoms of poststroke depression was done with Beck’s Depression Inventory, mini mental status examination tool, and Modified Motor Assessment Scale. The tests were performed independently by the participants except otherwise stated and scored on a scale of 0–6. Data were analyzed using -test for proportional significance and chi-square test for determining relationship between variables, at p < 0.05. Results. Twenty-one (42.0%) stroke survivors had symptoms of PSD, which was significantly dependent on duration of stroke ( = 21.680, df = 6, and p = 0.001), yet none of the participants had a psychiatry review. Conclusions. Symptoms of PSD may be common in cold compared to new cases of stroke and may need psychiatry care while on physiotherapy rehabilitation.

The automated transfer of flight logbook information from aircrafts into aircraft maintenance systems leads to reduced ground and maintenance time and is thus desirable from an economical point of view. Until recently, flight logbooks have not been managed electronically in aircrafts or at least the data transfer from aircraft to ground maintenance system has been executed manually. Latest aircraft types such as the Airbus A380 or the Boeing 787 do support an electronic logbook and thus make an automated transfer possible. A generic flight logbook transfer system must deal with different data formats on the input side – due to different aircraft makes and models – as well as different, distributed aircraft maintenance systems for different airlines as aircraft operators. This article contributes the concept and top level distributed system architecture of such a generic system for automated flight log data transfer. It has been developed within a joint industry and applied research project. The architecture has already been successfully evaluated in a prototypical implementation.

BACKGROUND: Despite their increasing popularity, little is known about how users perceive mobile devices such as smartphones and tablet PCs in medical contexts. Available studies are often restricted to evaluating the success of specific interventions and do not adequately cover the users' basic attitudes, for example, their expectations or concerns toward using mobile devices in medical settings. OBJECTIVE: The objective of the study was to obtain a comprehensive picture, both from the perspective of the patients, as well as the doctors, regarding the use and acceptance of mobile devices within medical contexts in general well as the perceived challenges when introducing the technology. METHODS: Doctors working at Hannover Medical School (206/1151, response 17.90%), as well as patients being admitted to this facility (213/279, utilization 76.3%) were surveyed about their acceptance and use of mobile devices in medical settings. Regarding demographics, both samples were representative of the respective study population. GNU R (version 3.1.1) was used for statistical testing. Fisher's exact test, two-sided, alpha=.05 with Monte Carlo approximation, 2000 replicates, was applied to determine dependencies between two variables. RESULTS: The majority of participants already own mobile devices (doctors, 168/206, 81.6%; patients, 110/213, 51.6%). For doctors, use in a professional context does not depend on age (P=.66), professional experience (P=.80), or function (P=.34); gender was a factor (P=.009), and use was more common among male (61/135, 45.2%) than female doctors (17/67, 25%). A correlation between use of mobile devices and age (P=.001) as well as education (P=.002) was seen for patients. Minor differences regarding how mobile devices are perceived in sensitive medical contexts mostly relate to data security, patients are more critical of the devices being used for storing and processing patient data; every fifth patient opposed this, but nevertheless, 4.8% of doctors (10/206) use their devices for this purpose. Both groups voiced only minor concerns about the credibility of the provided content or the technical reliability of the devices. While 8.3% of the doctors (17/206) avoided use during patient contact because they thought patients might be unfamiliar with the devices, (25/213) 11.7% of patients expressed concerns about the technology being too complicated to be used in a health context. CONCLUSIONS: Differences in how patients and doctors perceive the use of mobile devices can be attributed to age and level of education; these factors are often mentioned as contributors of the problems with (mobile) technologies. To fully realize the potential of mobile technologies in a health care context, the needs of both the elderly as well as those who are educationally disadvantaged need to be carefully addressed in all strategies relating to mobile technology in a health context.

BACKGROUND: Over the past decade, physician-rating websites have been gaining attention in scientific literature and in the media. However, little knowledge is available about the awareness and the impact of using such sites on health care professionals. It also remains unclear what key predictors are associated with the knowledge and the use of physician-rating websites. OBJECTIVE: To estimate the current level of awareness and use of physician-rating websites in Germany and to determine their impact on physician choice making and the key predictors which are associated with the knowledge and the use of physician-rating websites. METHODS: This study was designed as a cross-sectional survey. An online panel was consulted in January 2013. A questionnaire was developed containing 28 questions; a pretest was carried out to assess the comprehension of the questionnaire. Several sociodemographic (eg, age, gender, health insurance status, Internet use) and 2 health-related independent variables (ie, health status and health care utilization) were included. Data were analyzed using descriptive statistics, chi-square tests, and t tests. Binary multivariate logistic regression models were performed for elaborating the characteristics of physician-rating website users. Results from the logistic regression are presented for both the observed and weighted sample. RESULTS: In total, 1505 respondents (mean age 43.73 years, SD 14.39; 857/1505, 57.25% female) completed our survey. Of all respondents, 32.09% (483/1505) heard of physician-rating websites and 25.32% (381/1505) already had used a website when searching for a physician. Furthermore, 11.03% (166/1505) had already posted a rating on a physician-rating website. Approximately 65.35% (249/381) consulted a particular physician based on the ratings shown on the websites; in contrast, 52.23% (199/381) had not consulted a particular physician because of the publicly reported ratings. Significantly higher likelihoods for being aware of the websites could be demonstrated for female participants (P<.001), those who were widowed (P=.01), covered by statutory health insurance (P=.02), and with higher health care utilization (P<.001). Health care utilization was significantly associated with all dependent variables in our multivariate logistic regression models (P<.001). Furthermore, significantly higher scores could be shown for health insurance status in the unweighted and Internet use in the weighted models. CONCLUSIONS: Neither health policy makers nor physicians should underestimate the influence of physician-rating websites. They already play an important role in providing information to help patients decide on an appropriate physician. Assuming there will be a rising level of public awareness, the influence of their use will increase well into the future. Future studies should assess the impact of physician-rating websites under experimental conditions and investigate whether physician-rating websites have the potential to reflect the quality of care offered by health care providers.
