ICT integration by universities teaching professionals is emerging as a major concern, this study demonstrate the need to address the integration problem by encouraging existing metrics use in indexing ICT integration as an ICT governance strategy. Quality of integration depends on quality indexing which also depend on quality of existing metrics and their use. Considering the role that University Information Technology Teaching Professionals’ (UITTPs) continuous improvement indexing can offer, towards autonomic governance of the continuous emerging ICTs in the university teaching, this study examined extent in use of existing ICT integration metrics to index ICT integration by the UITTPs. Six metrics for ICT integration were investigated; time, workshop course content relevance, technical malfunctions, support conditions, support services, and motivation and commitment to student learning and staff professional development metrics. Descriptive survey design was used in which interviews were conducted to UITTPs in three (3) public and three (3) private purposively selected universities in Kenya. The findings were analyzed descriptively and inferentially using Kendall’s correlation of concordance and tested using Chi-square on the extent of concordance and presented with help of frequency tables, figures and percentages. The findings revealed that all the metrics are rarely used for indexing ICT integration (32.8%), and most UITTPs were in discordance on this level of all the six metrics use except for support condition. This implied that the use of metrics for indexing integration has not been formalized across the Kenyan universities. Universities need to be encouraged to identify suitable metrics, formalize them and improve their frequency in use. Secondly, socio based metrics such as content relevance are used more frequently for indexing integration as compared to Technical metrics, socio-technical metrics balance therefore need to be emphasized by the universities management when determining and using metrics for indexing ICT integration.
With trainings and research oriented towards sustainable development since 2006 (Water and Sanitation, Infrastructure, Renewable Energies and Energy Processes), Foundation 2iE is positioning itself as a reference institute that trains innovative engineers-entrepreneurs for the needs and challenges of Africa’s development. Center of Excellence of the UEMOA and the World Bank, CSR is at the heart of the Strategy of the institute which aims to be a showcase in this field in Africa.
Over the years, entrepreneurship has proven to be one of the key roles towards development. The cycle of business start-ups and growth are linked to the socio-economic benefits of the global world at large. With a growing world population of over 7billion people, the existence of universities (both public &private) as well as enterprises has increased globally in the 21st century. The mission and purpose behind Universities, Entrepreneurship and Enterprises thrive on development in the areas of capacity building, skill acquisition, training and knowledge amongst others. Africa alone has a population of over 1.2billion people with about 650 recognized universities and over 140,000 registered businesses (enterprises) in Ghana alone. A case study in Ghana reveals three key drivers towards entrepreneurship and the role university education has played in various business establishments. The drivers are problem statements, resources and research findings. Some of these notions to business include the management of risk, research findings and customer relationship. These are major features that need critical attention and play a role in business and entrepreneurship in Africa. A major success in business and entrepreneurship is the utilization of the human resource population and the lifeline support given to households in terms of income, while a barrier being the limited access to credit support from the financial companies at the inception stages. In conclusion, this conference should develop a practical book guide on business start-ups and entrepreneurship knowledge to be used at the various universities in Africa to enhance development.
Ghanaian tertiary graduates' perception of entrepreneurship education on employment opportunities
(2017)
This study focuses on whether entrepreneurship education increases entrepreneurial interest in students to set up new businesses. Entrepreneurship is a core course taken in the third year by all students of Ho Technical University. Out of the 1329 population of level 300 students of the 2016/2017 academic year, data were collected by convenience sampling from 325 (217 males and 108 females) with mean age of 24.75 years from 14 departments of four faculties. The students responded to 43-survey items derived from reviewed literature on a 5-Point Likert-Scale. It is concluded that more than 84% of the respondents agreed that entrepreneurship education informed students about entrepreneurship through the acquisition of practical skills, knowledge about acquisition of personal orientation, knowledge about business management principles and the availability of entrepreneurial support agencies. This shows that the students are highly confident of setting up their own businesses through the knowledge acquired. The study therefore has important implications for policy makers, management of tertiary institutions, students and educational evaluators on how to ensure that tertiary graduates set up entrepreneurship ventures in order to partially solve the unemployment problem in Ghana.

The incubator offers an opportunity to engage with practice-oriented and experience based learning applied to real.
"Bad usability equals no customer" – Mit diesem Zitat bringt Jakob Nielsen die große Bedeutung guter Usability auf den Punkt. Auch wenn Nielsen kommerzielle Unternehmen im Auge hat, so lässt sich auch für Bibliotheken die Relevanz ihres Webauftritts für den Kontakt zu ihren Benutzern oder potentiellen Benutzern nicht leugnen. In diesem Artikel soll dargestellt werden, wie Bibliotheken mit Hilfe von Usability-Tests die Schwächen ihres Webauftritts ermitteln können.
Die Frage, in welcher Umgebung Informationskompetenz in Hochschulbibliotheken erworben wird und wie sich die Gestaltung der Räumlichkeiten auf den Lernprozess auswirken kann, hat bisher in der Forschung wenig Aufmerksamkeit erhalten. Dieser Fragestellung geht die vorliegende Bachelorarbeit nach. Die Leitfrage lautet dabei: Wie kann die Gestaltung von Hochschulbibliotheksräumen den Erwerb von Informationskompetenz fördern?
This paper focuses on entrepreneurship and private sector development in Ghana with regard to the government’s initiative towards supporting private sector development through the Microfinance & Small Loans Centre (MASLOC) and the National Board for Small Scale Industries (NBSSI) initiatives to support new and existing small and medium-scale enterprises (SMEs) in diverse industries. The study addresses some of the main problems facing the two government-sponsored initiatives and issues with accessing venture capital for business start-ups in Ghana. The objective of the study is to identify possible strategies through which the MASLOC and NBSSI could be improved to serve the needs of their customers more effectively and efficiently. Enhancing the performance of these public organizations could offer many SMEs in Ghana take advantage of the new opportunities in the domestic and global business environments. The questions to be addressed are; to what extent do the activities of the NBSSI and MASLOC meet the needs of SMEs in Ghana? What challenges are associated with their services and how can management of the two organizations address the challenges they face more appropriately? The methodology is based on the qualitative and quantitative approaches, involving interviews and the administration of questionnaires and surveys to achieve the study’s objectives and goals. Based on the identified challenges, the study concludes with findings and recommendations for the management of NBSSI and MASLOC as well as entrepreneurs engaged in different SMEs in diverse industries and policy makers.

Computer-Sicherheitswarnungen – Benutzerzentrierte Entwurfsansätze der Usable Security-Forschung
(2017)
Der dritte und letzte Teil der Artikel-Serie in dieser Ausgabe zum Thema Usable Security zeigt exemplarisch, wie Softwareentwickler mit den im Rahmen des USecureD-Projekts entwickelten Werkzeugen arbeiten können. Der Beitrag konzentriert sich dabei auf Prinzipien, Richtlinien und Patterns, die bei der Ausgestaltung gebrauchstauglicher Computer-Sicherheitswarnungen berücksichtigt werden sollten. Anhand dieser sehr ubiquitären Bestandteile eines jeden digitalen Produkts kann anschaulich gezeigt werden, wie aktuelle wissenschaftliche Erkenntnisse auf dem Gebiet der Usable Security praxisnah für Softwarearchitekturen und Programmierer verfügbar und anwendbar gemacht werden können.
Damit IT-gestützte Produkte und Systeme vor unbefugter oder missbräuchlicher Nutzung wirksam geschützt sind, müssen sie mit Sicherheitsfunktionen ausgestattet sein, die benutzerfreundlich sind. Hierfür sind seitens der Entwickler sowohl Security- als auch Usability-Kenntnisse erforderlich. Da insbesondere Entwickler in kleinen und mittleren Unternehmen (KMU) oft nicht über tiefer gehende Kenntnisse in beiden Bereichen verfügen, bedürfen sie einer Unterstützung, z. B. in Form geeigneter Methoden und Werkzeuge. In diesem Beitrag werden ein Lösungsweg und eine Werkzeugsammlung vorgestellt, die Entwicklern in KMU dabei helfen, auf systematische Weise digitale Produkte und Systeme mit dem Qualitätsmerkmal Usable Security herzustellen.
„Sind Sie Gärtner oder Maschinist?“ (Zechlin 2010) – wer diese Frage einem Hochschulmanager stellt, der transportiert damit gleich dreierlei: zum einen die Frage, was für ein Typ man ist. Im Fokus steht der Hochschulmanager, der gießt, pflegt, vielleicht einmal die Äste stutzt, oder, im Gegenteil, den Hebel umlegt und erwartet, dass die Produktion läuft. Zum anderen stellt sich die Frage, um welches Gebilde es sich da eigentlich handelt, dem der Gärtner zum Wachstum und der Maschinist zur Produktivität verhilft. Zum Dritten offenbart sich die Frage nach dem Oder, also nach den vielfältigen denkbaren Konstellationen der beiden Pole Gärtner oder Maschinist sowie Gebilden, die weder Garten noch Maschine sind und ganz anderer Steuerungsimpulse bedürfen. Um Hochschulleitungen und Hochschulen zu beschreiben, gibt es, darauf deutet die Metapher hin, zahlreiche Modelle und Typologien. Die Praxis des Steuerungshandelns offenbart jedoch im Detail zahllose individuelle Ausprägungen und situationsbedingte Spezifika. Immer wieder heißt es, mit Blick auf die vielen Unterschiede müsse die Haltbarkeit von Annahmen und Modellen über Hochschulsteuerung am konkreten Einzelfall geprüft werden. In der Führungspraxis an einer Hochschule, hier am Beispiel der Hochschule Bonn-Rhein-Sieg, wird ein solcher Einzelfall beschrieben. Die per Gesetz gestärkte Hochschulleitung nutzte ihren Gestaltungsspielraum, um Hochschulentwicklungsplanungsprozesse nach eigener Aussage partizipativ vorzunehmen. Die partizipativen Prozesse sollten es ermöglichen, die Leitungsaufgaben im Hinblick auf Profilbildung, Richtungsweisung, Zukunftsgestaltung und Ressourcenzuweisung adäquat erfüllen zu können.

An increased bronchoconstrictor response is a hallmark in the progression of obstructive airway diseases. Acetylcholine and 5-hydroxytryptamine (5-HT, serotonin) are the major bronchoconstrictors. There is evidence that both cholinergic and serotonergic signaling in airway smooth muscle (ASM) involve caveolae. We hypothesized that caveolin-1 (cav-1), a structural protein of caveolae, plays an important regulatory role in ASM contraction. We analyzed airway contraction in different tracheal segments and extra-and intrapulmonary bronchi in cav-1 deficient (cav-1-/-) and wild-type mice using organ bath recordings and videomorphometry of methyl-beta-cyclodextrin (MCD) treated and non-treated precision-cut lung slices (PCLS). The presence of caveolae was investigated by electron microscopy. Receptor subtypes driving 5-HT-responses were studied by RT-PCR and videomorphometry after pharmacological inhibition with ketanserin. Cav-1 was present in tracheal epithelium and ASM. Muscarine induced a dose dependent contraction in all airway segments. A significantly higher Emax was observed in the caudal trachea. Although, caveolae abundancy was largely reduced in cav-1-/- mice, muscarine-induced airway contraction was maintained, albeit at diminished potency in the middle trachea, in the caudal trachea and in the bronchus without changes in the maximum efficacy. MCD-treatment of PLCS from cav-1-/- mice reduced cholinergic constriction by about 50%, indicating that cholesterol-rich plasma domains account for a substantial portion of the muscarine-induced bronchoconstriction. Notably, cav-1-deficiency fully abrogated 5-HT-induced contraction of extrapulmonary airways. In contrast, 5-HT-induced bronchoconstriction was fully maintained in cav-1-deficient intrapulmonary bronchi, but desensitization upon repetitive stimulation was enhanced. RT-PCR analysis revealed 5-HT1B, 5-HT2A, 5-HT6, and 5-HT7 receptors as the most prevalent subtypes in the airways. The 5-HT-induced-constriction in PCLS could be antagonized by ketanserin, a 5-HT2A receptor inhibitor. In conclusion, the role of cav-1, caveolae, and cholesterol-rich plasma domains in regulation of airway tone are highly agonist-specific and dependent on airway level. Cav-1 is indispensable for serotonergic contraction of extrapulmonary airways and modulates cholinergic constriction of the trachea and main bronchus. Thus, cav-1/caveolae shall be considered in settings such as bronchial hyperreactivity in common airway diseases and might provide an opportunity for modulation of the constrictor response.
In Africa slowly but steadily a transformation is taking place in the management styles of enterprises. There is a trend towards more precise time management, more precision in dealing with increasingly sophisticated technology, more feedback from the bottom to the top in order to manage the processes properly, more professionalism and independence of the individual worker.
This contribution makes two points: first, neither cultures nor the so-called mental states of individuals are ever static, but always on the move. Second, the force of passion and inspiration by which particular cultural values are endorsed in a particular context makes all the difference in their impact.
The importance of these two propositions comes to the fore, if the concept of an “economic culture” is taken into consideration. The claim of the authors is that the ongoing cultural transformation can be better understood in the dynamic approach of cultural values as proposed here.
BACKGROUND
Given the unreliable self-report in patients with dementia, pain assessment should also rely on the observation of pain behaviors, such as facial expressions. Ideal observers should be well trained and should observe the patient continuously in order to pick up any pain-indicative behavior; which are requisitions beyond realistic possibilities of pain care. Therefore, the need for video-based pain detection systems has been repeatedly voiced. Such systems would allow for constant monitoring of pain behaviors and thereby allow for a timely adjustment of pain management in these fragile patients, who are often undertreated for pain.
METHODS
In this road map paper we describe an interdisciplinary approach to develop such a video-based pain detection system. The development starts with the selection of appropriate video material of people in pain as well as the development of technical methods to capture their faces. Furthermore, single facial motions are automatically extracted according to an international coding system. Computer algorithms are trained to detect the combination and timing of those motions, which are pain-indicative.
RESULTS/CONCLUSION
We hope to encourage colleagues to join forces and to inform end-users about an imminent solution of a pressing pain-care problem. For the near future, implementation of such systems can be foreseen to monitor immobile patients in intensive and postoperative care situations.
