A Generalised Model of Ground Lease Pricing

Maria Trojanek, Marcin Anholcer, Audrius Banaitis, Radoslaw Trojanek
2018 Sustainability  
In this paper, we present a generalization of Mandell's model for the estimation of ground lease pricing. We adjust the model so that it fits, in particular, the Polish legal regulations and situation of the Polish real estate market. The model involves two aspects. The first is the perpetual usufruct, a form of owning the ground similar to a long-term lease, but having some specific features. The second is allowing lease rent adjustments after some fixed period, meaning we consider the
more » ... n where the payments are fixed during certain periods as defined in the contract. The proposed model determines the minimum lease amount for the owner, which is the rate at which it is beneficial to lease the property, and the maximum for the lessee, which is the amount above which the lease is unprofitable for the leaseholder or perpetual usufruct.

Selecting a construction contractor is a major decision which may influence the progress and success of any construction project. The paper analyses criteria used to evaluate qualification of contractors in Lithuania and abroad. Both in Lithuania and abroad, the bid price of construction works is the main criterion for evaluation of con‐tractors. The lowest price often cannot guarantee commitments on quality and duration of a construction project. Therefore, when selecting a contractor, a
more » ... must not only compare bid prices but also set other criteria for evalua‐tion of qualification and determine their weight. A contractor must be selected according to both quantitative and qualitative criteria, and bids should be compared. Only on the basis of quantitative and qualitative evaluation criteria and by comparing bids of contractors it is possible to select a qualified, competent and reliable contractor, to evaluate its qualification, economic and financial condition and technical capability and skills and to achieve relevant results in a construction project. The paper provides an investigation of Lithuanian companies, which analyses issues related to evaluation of contractors' qualification. The paper is completed with a discussion of the investigation results and delivery of proposals based on expert estimations of the weight of criteria for evaluation of contractors.

2019 Administrative Sciences  
Higher education institutions (HEIs), especially latecomer institutions, continue to regard exporting education services by creating a commercial presence in a foreign country with caution. The purpose of this paper is to investigate ways of creating and managing international branch campuses (IBCs) and to elaborate recommendations for universities on establishing a branch campus as an entry into the foreign education market. In order to reach this aim, we analyse the trends of IBC development

The analysis shows clear synergy between business theory and higher education (HE); however, no obvious coherence is discovered between the IBC establishment practices and the traditional Uppsala internationalisation model used in international business practices. This research continues by verifying the coherence of IBCs with the revisited Uppsala model based on the relationships and market commitment.

An Affect-Based Multimodal Video Recommendation System

2016 Studies in Informatics and Control  
People watching a video can almost always suppress their speech but they cannot suppress their body language and manage their physiological and behavioral parameters. Affects/emotions, sensory processing, actions/motor behavior and motivation link to the limbic system responsible for instinctive and instantaneous human reactions to their environment or to other people. Limbic reactions are immediate, sure, time-tested and occur among all people. Such reactions are highly spontaneous and reflect
more » ... the video viewer's real feelings and desires, rather than deliberately calculated ones. The limbic system also links to emotions, usually conveyed by facial expressions and movements of legs, arms and/or other body parts. All physiological and behavioral parameters require consideration to determine a video viewer's emotions and wishes. This is the reason an Affect-based multimodal video recommendation system (ARTIST), developed by the authors of the article, is very suitable. The ARTIST was developed and fine-tuned during the course of conducting the TEMPUS project "Reformation of the Curricula on Built Environment in the Eastern Neighbouring Area". ARTIST can analyze the facial expressions and physiological parameters of a viewer while watching a video. An analysis of a video viewer's facial expressions and physiological parameters leads to better control over alternative sequences of film clips for a video clips. It can even prompt ending the video, if nothing suitable for the viewer is available in the database. This system can consider a viewer's emotions (happy, sad, angry, surprised, scared, disgusted and neutral) and choose rational video clips in real time. The analysis of a video viewer's facial expressions and physiological parameters can indicate possible offers to viewers for video clips they prefer at the moment.

The role of strategic management is to handle the day-to-day needs of the firms with respect to current events of fluctuating markets so that they can effectively reach to their pre-planned, long-term goals. This study aims to explain the steps taken to design a new conceptual framework in the strategic management department of the National Iranian Gas Export Company (NIGEC), as well as the main components of the conceptual framework. It first goes through the logic behind the techniques
more » ... to design this conceptual framework, and then each component is explained as to why it works as part of an integrated conceptual framework. This new framework is part of a change regime in the organisation along with the whole oil industry in Iran aimed at contributing to directing the organisations confronted with rapidly altering environments. The insights of this study shed light on the basics of designing an adjusted conceptual framework for managers and researchers, and all companies faced with constant internal and external challenges and other characteristics of modern organisations.

2020 Buildings  
This paper aims to identify and investigate the factors affecting the goals of mass-housing building projects due to the use of building information modeling (BIM). A descriptive-survey method was used to collect necessary data. Fifty respondents from the target sectors and experts in the field of modeling building information participated in self-selection survey. The tools of collecting data included three questionnaires regarding three phases of construction work: pre-construction, during
more » ... struction and post-construction, which were developed based on the three indices of cost, time and quality. The face, content and construct validity of the questionnaires were confirmed after several rounds of testing. The reliability coefficient of the pre-construction, during the construction and post-construction questionnaires were 0.923, 0.917 and 0.876, respectively. The results show that the F-statistic is significant for the difference between the three groups (pre-construction, during construction and post-construction) at the 0.01 level. The results confirmed that BIM has a great influence on a project in terms of meeting time, cost and quality objectives through the whole life cycle of a construction project: during pre-construction, construction, and post-construction stages.

Construction, as an object of marketing, has special features: the construction environment is complex and changing, clients' requirements and expectations are increasing. Construction companies must realize that good marketing, as well as advertising activities have a great impact on sales of construction products and services in today's competitive market. This paper reports on a qualitative study of the Lithuanian and Swedish construction companies about advertising campaign, budget and
more » ... of advertising. The effectiveness of advertising means is also analyzed. The first problem identified in the study is that most Lithuanian construction companies provide self‐advertising policy. The lack of experience and knowledge of advertising leads organizations to inadequate decisions. The observations also detected that advertising campaign in the Lithuanian construction companies is underfinanced and the advertising budget is closely linked with used means. The paper concludes with the assessment of the study results and directions for further research.

The construction client satisfaction model: a PLS-SEM approach

2018 Journal of Civil Engineering and Management  
The satisfaction of the client is of utmost importance in procuring future projects; however, anecdotally client satisfaction (CS) is not adequately considered in many developing countries. Factors associated with the influence of service quality (SQ) on construction client satisfaction and how it affects their behavioural intentions in Cambodia are investigated. A theoretical structural model was developed to investigate the influence of five SQ factors on CS and their links to the future
more » ... ioural intentions of the client. A partial least square approach of the structural equation modelling technique (PLS-SEM) was employed to analyse data collected from a questionnaire survey of 227 participants comprising the clients of small and medium size projects. The structural model adapts 22 attributes across five SQ factors, namely: reliability; responsiveness; assurance; empathy, and tangible factors. PLS-SEM outcomes confirmed that the future behavioural intentions of the client are influenced by their satisfaction over the service excellence provided by construction companies. Moreover, treating every client individually and demonstrating an approachable attitude towards their needs will increase their satisfaction with the experience they had with a contractor. Findings and recommendations of the study may be useful to construction companies who are seeking ways to improve CS in developing countries.

Office buildings built before the pre-1960 age constitute a relevant group for analyzing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. By using a staged renovation approach, two passive technologies applied to the building envelope and an efficient domestic hot water system were selected and a financial evaluation through the net saving (NS)
more » ... method was undertaken to choose the best efficiency measures/packages for improving the building's energy performance. Real discount rates of 3% and 1% were used in the financial evaluation. Considering the real discount rate of 3%, the results showed that only two out seven retrofit options had a positive financial return. By using the real discount rate of 1%, all retrofit options were found to be financially efficient. The results of the study corroborated those of earlier works that found that the financial profitability of energy renovation investments is very sensitive to the discount rate used in the analysis. The results of the study also suggested that the staged renovation approach used in the analysis is economically feasible, and that this approach is an alternative to one-step renovation approach to help to achieve the country´s energy and climate targets by 2030. Suggestions for future research conducted for office buildings in the different climate zones and other age groups in Portugal are proposed.
