The Impact of Real Estate Taxations on the Inter-municipal Migration Which Influences the Housing Construction Dynamics

This study investigates the Tiebout-Tullock hypothesis of “voting with one’s feet”, using NUTS5-level data for the year of the first real estate appraisal in Slovenia, 2011. The general approach is developed and the case study for Slovenia is presented. This analysis differs from previous related studies by Tullock, Cebula and other authors because the income tax burden in Slovenia is equal in all spatial units. However, the housing property tax burdens, which have not been introduced yet, but will be in the near future, are supposed to be different in different municipalities. We have found that the existence of local property taxes has strongly influenced migration patterns over time, therefore it can also influence the dynamics of needed real estate construction. From the study, we can conclude that the flows to the areas of smaller percentage of total population are more sensitive to changing housing property burdens. This finding means that spatial planners, who are planning the future construction of housing, and investors in constructions in the municipalities need to adjust their forecasts regarding the supply and demand of housing units also to the future real estate taxation policies, whereas the local authorities have to be aware how their taxation policy might influence the growth or decline of their urban area. The numerical results are limited by parameters of the gravity model on the NUTS5-level in Slovenia.

Developing a Pre-scale for Evaluating Supervisors’ Directive Style in Continuous Improvement Environments

The level of workers’ commitment and participation has a huge impact on the success of continuous improvement initiatives. One of the non-written duties of middle managers is creating a trust-culture that enhances commitment and participation, which can be achieved with the appropriate directive style. In this paper, we present a pre-scale of four dimensions and fifty-five middle managers’ behaviors that encourage employee commitment towards and participation in continuous improvement activities. The list has been developed putting together the opinions of operators and supervisors, as well as businessmen, university professors and consultants.

Mandatory Convertible Bonds as an Efficient Method of Issuing Capital

Mandatory Convertibles Notes (MCNs) mean only a small fraction of all the securities issued by corporate or financial institutions, however, they represent nearly a 30% in volume of the convertible securities issued every year. MCNs share characteristics of equity and debt securities but rating agencies assign them a high equity component and are commonly treated as equity by accounting standards. Despite the high facial coupon that MCNs seem to pay, a deeper analysis shows that the cost of MCN can be lower than the cost of issuing hybrid or subordinated debt and in some cases similar to the cost of issuing senior debt. Mandatory convertibles were profusely issued by financial institutions amid the global crisis as a means to increase capital and could be considered as a predecessor of some types of AT1 and Contingent Convertible. The academic literature about Mandatory Convertibles is scarce and we consider necessary to shed some light on a type of security that can be very useful for the real economy.

Culture and Environment as Antecedents of Technological Entrepreneurship

The present research points out how engineering students from two different countries, and therefore subject to different cultural and role models, show different entrepreneurial intentions. A questionnaire was submitted to engineering students divided into two groups on the basis of their country origin: Italy and Spain. The sample in use is for students attending Engineering Schools, as engineers are considered as possible founders of future innovative start-ups. The results of the survey show that Italian students have higher entrepreneurial intentions than Spanish ones. This is attributed to their different cultural origins and in particular, the sub-dimensions of individualism and masculinity from Hofstede’s Cultural Dimension Theory. Among the results of the research, it has been proved that students whose parents are entrepreneurs present higher entrepreneurial intention than those whose parents are not self-employed.

A Study on Consumer Behaviour in the Sharing Economy

Sharing economy is a socio-economic model, built around the sharing of human and physical resources, which give consumers the possibility of accessing to product and assets without having the individual ownership. The present research has the purpose of analysing consumers’ intentions to join in with sharing economy system, and, in particular, of focusing on how this participation is influenced by Hofstede’s cultural dimensions and Materialism. Data for this study were collected by distributing a questionnaire among engineering students from two technical universities, respectively in Italy and Spain, in order to observe the different behaviour about sharing intention. The obtained results point out that cultural dimensions like Collectivism and Femininity foster sharing intention and that, therefore, consumers’ attitude to join in with sharing economy, whereas Individualism and Masculinity inhibit sharing intention. It is possible to say the same thing about Materialism that, as demonstrated by the results of the research, has a negative impact on sharing intention, considered as one of the principal inhibitors of sharing.

Levels of Application of Public R&D&I Policy Models

With the analysis by researchers and institutions regarding experiences in designing public R&D&I policies, to strengthen the capacity of innovation in the industrial sector, international cooperation was possible to understand the difficulties and recommendations for linking and integrating SMIs with the other members of the Innovation System. With this information, four levels of implementation of public policy models in R&D&I are presented. Among the proposed alternatives level 4 is the one recommended since it presents the best model of integration, coordination and governmental evaluation in the design of public R&D&I policies.

Limitations and Pitfalls of the Brain That Prevent Us from Thinking

When we think or make decisions, we must not forget that there are several internal “pitfalls” that cause our brain to make decisions incorrectly. Many authors have written on various pitfalls that may affect us. In this paper, five of them are identified and they are: The use of patterns when thinking, the relativity of things, the anchor effect, loss aversion, value attribution and diagnosis bias.

Lessons Learned in Assessment of Technology Maturity

Maturity is a stage in the technology life cycle where technology is highly competitive and it can (safely) be integrated into products or processes. This article analyzes the most important methods to assess maturity and proposes a method based on their best features. On the one hand, Future-oriented Technology Analysis, an approach that incorporates different decision-taking techniques. On the other hand, Technology Readiness Levels, a quantitative scale used to measure technology’s progress. The proposed approach uses logistic-growth fitting to match technology publication trends to the Technology Readiness Level scale. Three technologies at different maturity levels were successfully tested.

Resilience Engineering: Concepts of the New Paradigm

Resilience Engineering is a new safety paradigm that considers that the way duties are normally performed is something that is subject to variability, and since change is necessary to achieve success it should not be restricted. People in this complex context are continuously making adjustments to the original design, enabling them to achieve success, but occasionally accidents also arise due to an incomplete analysis of the current conditions. Thus, linear, simple or complex causation models do not reflect the ongoing reality, which is essentially non-linear, besides being complex. The accident “emerges” from normality, due to concurrent events that “resonate”, and are not “caused” by a simple chain of errors. Therefore, new tools are required to analyse accidents and indicators to monitor processes, even though most simple incidents continue to be dealt with in the usual manner.

The Importance of Intangible Liabilities to Business Management

The intangible assets of the company are those non-tangible aspects that have been identified as internal strengths and external opportunities, while intangible liabilities are internal weaknesses and external threats of a tacit and non-explicit nature. Both, in most cases, do not become visible outside the company. However, these intangible assets have a specific accounting item, an issue that does not occur for intangible liabilities, which prevents their recognition and effects for the company. Consequently, the objective of this paper is to identify and analyze the existence of intangible liabilities in the company as factors that, as opposed to intangible assets, produce losses that are difficult to quantify, but absolutely necessary to know the generation of strategic value And accounting, of the company.

Analysis of the Customer Service Rate and Reliability of Suppliers in a Production and Assembly Multinational Company

This study arises from the need to improve the goals or objectives set for the supply chain management department of a multinational company in the electric sector given the successive poor results achieved in service rates, and also from the need to merge two different management models: the traditional company model and the multinational company model. To fulfill this objective, a simulation model was built by the system dynamics method and using the Vensim® simulation software. After simulating the different processes that encompass the activity of the supply chain under study, the obtained results were analyzed and different scenarios were simulated according to the proposed objectives. Then whether these objectives were actually fulfilled was verified, the best economic results were selected and possible future lines of action were set out.

Quantitative Techniques to Effectively Link Enterprise’s Performance and Lean Production

Lean Production has been widely applied in the last decades and it is generally accepted as a tool to improve the operations of organisations. However, how to properly quantify such an improvement is still not clear from a global and integrated point of view. The fact that the data gathered from applying LP production techniques—at the operative level—should be somehow correlated with the enterprise strategic objectives one—at the strategic level—presents important challenges to decision makers. This papers sets up this research topic, covering some relevant scientific literature, moving then to define a classification of important factors to take into account when deciding what quantitative technique to apply to this topic. Then, following such a classification, it assesses some quantitative techniques that could be used, mainly broken down into either objective or subjective. From this evaluation, it concludes that, from the evaluated, the most appropriate technique to be used should be the Analytic Network Process.

When to Stop? A New Stop Criterion for Combinatorial Optimization Search Techniques

This research draws on theories in discrete event simulation, order statistics and record-breaking statistics to develop a methodology for deciding when to stop a combinatorial optimization search. During the first optimization period, the objective function improves rapidly with the iterations, and the improvement slows gradually until it almost stalls. We adopt a popular method to detect the period of rapid improvements of the “warm-up period”, and then we propose a special control chart technique to identify with a given certainty reaching a steady state. Then, we suggest using the theory of record-breaking to decide on a stopping criterion. In addition, the paper develops estimates for the optimum bounds and estimates for value and timing of the next expected improvement. The advantages of this approach are discussed.

Qualitative Patents Evaluation Through the Analysis of Their Citations. Case of the Technological Sectors in the Basque Country

Patents are an output of the level of innovation of a company or region. Patent quantitative studies are performed by simply counting the number of these documents. For the qualitative evaluation, there is a certain consensus among the authors to consider the citations as the most adequate indicator. However, this indicator presents several problems regarding its correct interpretation. In the present study, in order to avoid the typical citation interpretation biases, a precise methodology is presented. As an illustrative example, we present a comparative study of the quality of patents in technological sectors of the Basque Country region over the period 1991–2011.

Managing Volunteer Assignment in a Sport Event

Any sport event can count with volunteers to support the rest of participants (organizers, officials…). This group usually concentrates an important number of collaborators who work selflessly, but with heterogeneity of profiles. The organizational success of these events depends to a large extent on their efficiency in the assigned tasks. Here, it is designed a methodology that generates an assignment of volunteers to tasks, taken into account the suitability of each person to the operations to be performed. One of the stages in the methodology is based in the resolution of a Mixed Integer Linear Program. This methodology is evaluated and applied to data from a world event.

Using a Serious Game for the Practical Learning of Productive and Environmental Efficiencies

The increase in environmental and social awareness has triggered numerous green initiatives at companies. Traditionally, companies’ training related to environmental management focuses on technical aspects and theoretical concepts. In addition to these theoretical contents, it is necessary to carry out practical activities to impart the desired behaviors and skills. Serious games have been found to improve employees understanding of practical environmental sustainability challenges, by offering opportunities to obtain first-hand experiences that may otherwise be too costly and difficult to reproduce in reality. This work presents Pizz@green, a serious game which simulates the productive and environmental efficiencies generated by the improvements of processes in a pizza shop. The purpose of the game is the practical learning of the environmental impact caused by the production processes of a company.

Formative Assessment for the Analysis and Problem Solving Transversal Competence in Master Degree

The Universitat Politècnica de València has introduced thirteen transversal competences in the curricula of undergraduate and graduate degrees. One of the transversal competences is “Analysis and Problem Solving”. This competence had been assessed non-uniformly in the Master Degree in Advanced Engineering Production, Logistics and Supply Chain due to the fact that the assessment lacked a comprehensive and accessible tool to the students that exposed the indicators and levels of achievement of the competence. In addition, it was important to design a tool where all the instructors agreed on the main features so that the tool could be used in both semesters by instructors aiding to support the formative assessment of the competence. This paper presents a methodology and the design of a tool to perform formative assessment of analysis and problem solving competence. It had been implemented in three courses (three pilot applications) and five learning activities to support the formative assessment as well as to update the tool with the feedback collected by each pilot application. The analysis of the pilot applications show the positive results obtained and the recommendation of students for its implementation.

Logistics and Supply Chain

An Overview of Supply Chain Planning That Integrates Financial Issues

The main ambition of a supply chain manager is to ensure correct flows of goods and information through all the supply chain nodes to guarantee the right goods in the right place at the right time. To achieve these results, it is very important to consider the flow of items and finances to and from supply chain nodes, which is generated by market demand and productive capacity. In line with a supply chain manager’s objective, this paper presents an overview of supply chain modeling methodologies, and analyzes the applicability of current methods and tools to model econometric systems for supply chain planning.

Adaptive and Hybrid Forecasting Models—A Review

Nowadays, good supply chain management is most important to guarantee a competitive advantage and to accomplish the value promise offered to the company’s clients. To this end, it is important to reduce uncertainty associated with demand, and it is important that demand forecast is as accurate as possible. To achieve this, it is necessary to know the features of the demand to be forecast and, based on this, to build or choose the best and the most accurate model or technique, which is based normally on that with fewer errors. Many statistical techniques exist, but for some 20 years, many heuristic algorithms have been developed that allow to absorb the variance associated with demand, and to reduce forecasting errors with better results than those obtained by statistical methods. These methods are normally adaptive and allow to hybridize techniques to construct different models. This document reviews these adaptive techniques, such as neural networks (NN) and hybrid methods, and in particular models based on case-based reasoning (CBR).

Towards a Sustainable Agri-food Supply Chain Model. The Case of LEAF

The Agri-food Supply Chain (ASC) has received increasing attention lately due to environmental and social impacts. This is likely to lead to tighter regulations and closer control of these supply chains, where the traditional ASC practices will be reviewed and changed. One of the key solutions may be the necessity of establishing procedures accounting for the sustainability of the whole ASC. This is directly related to the increasing presence of different ASC third parties offering this type of services. In this paper, different aspects about ASC sustainability are reviewed from the literature, with the aim of finding out which are the most addressed and remarkable ones. These ones will be used as a benchmark against an example of a real sustainable ASC management model implemented by the UK established company (LEAF-Linking Environment And Farming).

A Simulink Library for Supply Chain Simulation

Despite the links between forecasting and inventory control, both areas have evolved separately. This work presents a supply chain simulation library developed in Simulink to bridge that gap. To simulate a supply chain is important to define the number of companies/echelons that belong to the same supply chain and the policies that each company employs to demand forecasting and stock control. The potential user can find in this library forecasting and stock control blocks to simulate a supply chain in a modular design. We show how to implement: i) Forecasting policies. For example, the widely used exponential smoothing; ii) Replenishment models. For instance, typical order-up-to-level stock control policies as (s, S); and finally, how to connect the forecasting and stock control blocks to describe the performance of a company and to extend such relationships to define the whole supply chain.
