Application of real options analysis for pharmaceutical R&D project valuation—Empirical results from a survey     

Marcus Hartmann  Ali Hassan 《Research Policy》2006,35(3):343-354

Real options analysis was often recommended as an emerging valuation technique for high-risk investment projects. Former inter-sectoral surveys have drawn an ambivalent picture of real options usage in general. In addition, there is a lack of sector-specific investigations. In the following article the results of an in-depth analysis of collected empirical data regarding the application of this new tool in the pharmaceutical sector is presented by capturing the internal view from the pharmaceutical companies themselves and the external view from the health care departments of financial service firms. R&D stage specific modi of application, reasons for reluctance in the employment of real options and their assumed future prospects are elucidated.  相似文献   

The Teacher Behavior Inventory: validation of teacher behavior in an interactive lecture environment     

Siti Nurma Hanim Hadie  Asma’ Hassan  Saiful Bahri Talip  Muhamad Saiful Bahri Yusoff 《Teacher Development》2019,23(1):36-49

Students’ rating of teacher behaviors provides valuable information on teaching improvement and instructional quality. Unfortunately, there is a lack of new validated instruments for measuring teacher behaviors. The Teacher Behaviors Inventory is an old inventory that was initially developed to measure teaching behaviors as regards lecture-based instructions, which is effected through the use of low-inference items. The aim of this study was to assess its continued suitability in the present educational setting by examining its construct validity and internal consistency through the lens of one lecturer’s teaching behaviors, as rated by 527 students after six interactive lectures. The variables evaluated, as mentioned above, were achieved after an items removal process, which resulted in a 32-item version. Apart from being valid and reliable, this condensed version allows for immediate assessment of teaching behaviors after an instruction session as the rating procedure is now more straightforward and less time-consuming, and also enables a reduction in rating errors. Therefore, the 32-item format serves as a practical diagnostic feedback tool in the present educational arena, permitting a longitudinal teaching behavior assessment to enhance teachers’ professional development.  相似文献   

Repulsion-based model for contact angle saturation in electrowetting     

Hassan Abdelmoumen Abdellah Ali  Hany Ahmed Mohamed  Mohamed Abdelgawad 《Biomicrofluidics》2015,9(1)

We introduce a new model for contact angle saturation phenomenon in electrowetting on dielectric systems. This new model attributes contact angle saturation to repulsion between trapped charges on the cap and base surfaces of the droplet in the vicinity of the three-phase contact line, which prevents these surfaces from converging during contact angle reduction. This repulsion-based saturation is similar to repulsion between charges accumulated on the surfaces of conducting droplets which causes the well known Coulombic fission and Taylor cone formation phenomena. In our model, both the droplet and dielectric coating were treated as lossy dielectric media (i.e., having finite electrical conductivities and permittivities) contrary to the more common assumption of a perfectly conducting droplet and perfectly insulating dielectric. We used theoretical analysis and numerical simulations to find actual charge distribution on droplet surface, calculate repulsion energy, and minimize energy of the total system as a function of droplet contact angle. Resulting saturation curves were in good agreement with previously reported experimental results. We used this proposed model to predict effect of changing liquid properties, such as electrical conductivity, and system parameters, such as thickness of the dielectric layer, on the saturation angle, which also matched experimental results.  相似文献   

International student satisfaction with,and behavioural intentions towards,universities in Victoria     

Siti Falindah Padlee  Vaughan Reimers 《Journal of Marketing for HIGHER EDUCATION》2015,25(1):70-84

International students make a vital contribution to the Australian economy. Due to their importance, a number of studies have been undertaken to examine the living experiences, attitudes and behaviours of international students in Australia. However, very few studies have examined international students' overall satisfaction with their university experience. The primary objective of this paper is to measure the influence of six individual university service factors on international students' satisfaction, and its subsequent impact on behavioural intentions. The results from the structural equation modelling analysis revealed that overall student satisfaction is influenced by the level of satisfaction with academic services, courses offered, access and augmented services. In contrast, administrative services and physical evidence were found to have a non-significant impact on overall satisfaction. Analysis also revealed a strong relationship between overall satisfaction and behavioural intentions.  相似文献

Observer design for constrained nonlinear systems with application to secure communication     

Mohamed F. Hassan 《Journal of The Franklin Institute》2014

In this paper, a constrained regularized least square (RLS) state estimator is developed for deterministic discrete-time nonlinear dynamical systems subject to a set of equality and/or inequality constraints. The stability of the estimation error is rigorously analyzed. The proposed estimator is then used to handle the important problem of secure communication. At the transmitting end, the output of the constrained unified chaotic system is used as a chaotic mask to achieve a satisfactory and typical secure communication scheme. The encrypted data signal is injected into the transmitter and simultaneously transmitted to the receiver through a public channel. At the receiving end, the constrained RLS estimator is used to reconstruct the states of the constrained unified chaotic system. Simulation results are presented to show the impact of the imposed constraints on the waveform and the pattern of the generated chaotic signal as well as the ability of the proposed estimator to synchronize the actual and estimated states of the constrained unified chaotic system. Moreover, the proposed estimator is applied to recover discrete signals such as digital images where computer simulation results are provided to show the effectiveness of the proposed estimation scheme.  相似文献   

Perception of spiritual health: A qualitative content analysis in Iranian older adults     

Hosein Ajam Zibad  Farahnaz Mohammadi Shahboulaghi  Hassan Rafiey  Maryam Rassouli 《Educational gerontology》2017,43(1):21-32

The present study was performed with the aim to explain older people’s perceptions of spiritual health. It was conducted using the conventional content analysis method. Twelve individuals aged 60 years or older with normal cognition participated in the study using purposive sampling. Data were collected by in-depth interviews. Data analysis performed using standard method of thematic analysis.The average age of the study participants was 71.25 ± 9.48. The data analysis resulted in three main categories of spiritual insight, spiritual function, and spiritual affection. The spiritual insight included cognition of God and belief in Him, understanding of the divine religions and belief in them, self-cognition, cognition of the creation, and belief in the hereafter. This category included the two subcategories of spiritual cognition and spiritual belief. Spiritual function represented the interactions that the older people experienced in relations with God, themselves, and others. This category consisted of the subcategories of relationship with God, relationship with others, and self-cultivation. The spiritual affection included loving God and other humans and consisted of the three subcategories of spiritual affections to God, others, and oneself. This study presents in-depth data on the concept of spiritual health from older people’s viewpoints. These findings would help healthcare teams in designing appropriate interventions for older people’s health promotion. Also, by using the results of this research, health researchers design more appropriate tools for measuring spiritual health based on older people’s perception of the concept of spiritual health.  相似文献   

Shaping global teacher identity in a short-term mobility programme     

Donna Tangen  Deborah Henderson  Jennifer Alford  Erika Hepple  Amyzar Alwi  Zaira Abu Hassan Shaari 《Asia-Pacific Journal of Teacher Education》2017,45(1):23-38

This article explores the shaping of Australian and Malaysian pre-service teachers’ possible selves in a short-term mobility programme. With the theory of possible selves, individuals imagine who they will become based on their past and current selves. The focus of the research was on pre-service teachers’ possible selves as global and culturally responsive teachers. The experiential learning through participation in the programme allowed participants to consider their future possible selves as teachers with a deeper understanding of diverse learners’ needs and how they might strive to address these needs in their own classrooms. The scaffolding of reflections in the programme encouraged the pre-service teachers to take on multiple perspectives, to step outside their comfort zones and in many ways to see the world from different eyes. The research found that through experiential learning in the short-term mobility programme both the Australian and Malaysian pre-service teachers gained in positioning their cultural selves currently and as future teachers, suggesting that there is merit in utilising the theory of possible selves in future research in the area of shaping teacher identity.  相似文献   

The influence of academic culture on quality management system ISO 9001 maintenance within Malaysian universities     

Siti Arni Basir  John Davies  Jacqueline Douglas  Alexander Douglas 《Journal of Higher Education Policy & Management》2017,39(3):320-340

This study investigates the influence of the elements of academic culture on quality management system ISO 9001 maintenance within Malaysian universities. There is a dearth of empirical studies on maintaining ISO 9001, particularly in the higher education context. From the literature review, academic culture was classified according to four elements – academic freedom, individualism, professionalism and collegiality. Two case studies were conducted within Malaysian universities that had been ISO 9001-certified for 5 years. At the time of this research, these two were the only universities that had certification for their entire organisation. (Most organisations gain certification for specific departments). The findings showed that academic freedom, individualism and collegiality had worked against ISO 9001 maintenance, while professionalism had influenced ISO 9001 maintenance both positively and negatively. The opposites of individualism (teamwork) and collegiality (managerialism) had supported ISO 9001 maintenance in one of the cases.  相似文献   

Preparing a Data Scientist: A Pedagogic Experience in Designing a Big Data Analytics Course          下载免费PDF全文

Daniel Adomako Asamoah  Ramesh Sharda  Amir Hassan Zadeh  Pankush Kalgotra 《Decision Sciences Journal of Innovative Education》2017,15(2):161-190

In this article, we present an experiential perspective on how a big data analytics course was designed and delivered to students at a major Midwestern university. In reference to the MSIS 2006 Model Curriculum, we designed this course as a level 2 course, with prerequisites in databases, computer programming, statistics, and data mining. Students in the class were mostly seniors or at the graduate level, and had a strong technical and quantitative background. We include details of concepts covered in the course, as well as summaries of four major sample course assignments used. Some of the concepts covered include large‐scale data collection and management using the Hadoop ecosystem, stream mining, visual analytics, and social network analytics. Besides Hadoop, the course also introduced various IBM and Teradata big data tools. We show how the course modules align with the intended learning goals and course objectives. A post‐course survey indicated that the structure and organization of the course helped students clearly and concisely assimilate the course content.  相似文献
