Consumer valuation of energy-saving features of residential air conditioners with hedonic and choice models

The promotion of energy-efficient appliances is necessary to reduce the energetic and environmental burden of the household sector. However, many studies have reported that a typical consumer underestimates the benefits of energy-saving investment on the purchase of household electric appliances. To analyze this energy-efficiency gap problem, many scholars have estimated implicit discount rates that consumers use for energy-consuming durables. Although both hedonic and choice models have been used in previous studies, a comparison between two models has not yet been done. This study uses point of sale data about Japanese residential air conditioners and estimates implicit discounts rates with both hedonic and choice models. Both models demonstrate that a typical consumer underinvests in energy efficiency. Although choice models estimate a lower implicit discount rate than hedonic models, the latter models estimate the values of other product characteristics more consistently than choice models.

El rol de la marca en la comunicación del espacio turístico

El turismo es a menudo el aspecto promocional más visible en el proceso de creación y proyección de una determinada imagen territorial. Esto es debido a que la actividad turística acumula un amplio bagaje en aspectos vinculados a la comercialización de espacios geográficos, y esta circunstancia incide, por ejemplo, en la presencia de numerosa literatura relacionada con la promoción, el marketing y el branding de espacios turísticos. A nivel metodológico, se ha optado por un análisis de fuentes documentales, que ha servido para fijar los cimientos de la evolución de la comunicación de los espacios turísticos mediante el uso de marcas. Se concluye que el registro de la comunicación turística ha experimentado una clara mutación en base a una doble dualidad: de la información a la persuasión y de la promoción a la emoción. Asi mismo, el trabajo en cuestión muestra de qué forma la estrategia comunicativa transcurre nuevamente entorno a las necesidades emociona les del potencial turista y/o visitante en detrimento de las necesidades de información subyacentes al propio destino turístico.

Rewards for Motivating Employees

When considering ways to motivate employees, one must keep in mind that each individual is different and therefore everyone is motivated in different way. Employees can have quite different motivators, for example, more money, more recognition, flexible working hours, promotions, opportunities for learning, or discounts for employee and his/her family. Therefore, when attempting to help motivate people, it is important to discover what the individual motivation factors are for each one personally. Another key factor is the variation over time. Nobody experiences a constant set of needs over time, it will change slowly. One of the most fundamental concerns of reward management is how it can help to motivate people so that they achieve their full potential. The development of a performance culture is a typical aim of reward strategy. It is therefore necessary to understand the factors that motivate people and how, in the light of these factors, rewarding process and practices that will enhance motivation, commitment, job engagement and positive discretionary behavior, can be developed. The purpose of this research is to examine more in detail of the total reward systems which are used in two public sectors and their cultural differences and/or similarities. The study is focused on two different public sectors; Vantaa City Authority (Finland) and Hertfordshire County Authority (the United Kingdom). The research questions are: How do public sector employers attempt to reward their employees with a total reward system? • What are the different ways to motivate employees? • What is the reward system in the public sector based on? • What characteristics are included in the total reward system? • How does the culture affect the ways of motivation and rewarding? The benefits of a total reward approach are, for example, the greater impact which means that the combined effect of the different types of rewards will make a deeper and longer-lasting impact on the motivation and commitment of people. It also enhances the employment relationship, meaning that the employment relationship created by a total rewards approach makes the maximum use of relational as well as transactional rewards and will therefore appeal more to individuals. The research findings point out that in Finland rewards are based on just for the employees, recognition of individuals is high, in several cases they reward teams, and organisation climate is important issue for them. In the United Kingdom, the reward system is based on rewarding employees and their families, employer offer several discounts for employees and families, and flexible working hours are favourable.

Optimization as a method of search engine marketing

This study is dedicated to search engine marketing (SEM). It aims for developing a business model of SEM firms and to provide explicit research of trustworthy practices of virtual marketing companies. Optimization is a general term that represents a variety of techniques and methods of the web pages promotion. The research addresses optimization as a business activity, and it explains its role for the online marketing. Additionally, it highlights issues of unethical techniques utilization by marketers which created relatively negative attitude to them on the Internet environment. Literature insight combines in the one place both technical and economical scientific findings in order to highlight technological and business attributes incorporated in SEM activities. Empirical data regarding search marketers was collected via e-mail questionnaires. 4 representatives of SEM companies were engaged in this study to accomplish the business model design. Additionally, the fifth respondent was a representative of the search engine portal, who provided insight on relations between search engines and marketers. Obtained information of the respondents was processed qualitatively. Movement of commercial organizations to the online market increases demand on promotional programs. SEM is the largest part of online marketing, and it is a prerogative of search engines portals. However, skilled users, or marketers, are able to implement long-term marketing programs by utilizing web page optimization techniques, key word consultancy or content optimization to increase web site visibility to search engines and, therefore, user’s attention to the customer pages. SEM firms are related to small knowledge-intensive businesses. On the basis of data analysis the business model was constructed. The SEM model includes generalized constructs, although they represent a wider amount of operational aspects. Constructing blocks of the model includes fundamental parts of SEM commercial activity: value creation, customer, infrastructure and financial segments. Also, approaches were provided on company’s differentiation and competitive advantages evaluation. It is assumed that search marketers should apply further attempts to differentiate own business out of the large number of similar service providing companies. Findings indicate that SEM companies are interested in the increasing their trustworthiness and the reputation building. Future of the search marketing is directly depending on search engines development.

Integration of existing military capability models into the Comprehensive Capability Meta-model

Abstract—This paper discusses existing military capability models and proposes a comprehensive capability meta-model (CCMM) which unites the existing capability models into an integrated and hierarchical whole. The Zachman Framework for Enterprise Architecture is used as a structure for the CCMM. The CCMM takes into account the abstraction level, the primary area of application, stakeholders, intrinsic process, and life cycle considerations of each existing capability model, and shows how the models relate to each other. The validity of the CCMM was verified through a survey of subject matter experts. The results suggest that the CCMM is of practical value to various capability stakeholders in many ways, such as helping to improve communication between the different capability communities.

The holistic military capability life cycle model

Abstract - This paper reviews existing military capability models and the capability life cycle. It proposes a holistic capability life-cycle model (HCLCM) that combines capability systems with related capability models. ISO 15288 standard is used as a framework to construct the HCLCM. The HCLCM also shows how capability models and systems relate to each other throughout the capability life cycle. The main contribution of this paper is conceptual in nature. The model complements the existing, but still evolving, understanding of the military capability life cycle in a holistic and systemic way. The model also increases understanding and facilitates communication among various military capability stakeholders.

The Application of Enterprise Architecture Approach to Military Concept Development–Case Study

Abstract—Concept development and experimentation (CD&E) plays an important role in driving strategic transformation in the military community. Defence architecture frameworks, such as the NATO architecture framework, are considered excellent means to support CD&E. There is not much empirical evidence, however, to indicate how enterprise architectures (EA) are applied in the military community or particularly in military CD&E. Consequently, this paper describes and discusses empirical application of the EA approach in CD&E. The research method in the paper is a case study. Situational method engineering (SiME) is used as a framework to adapt the EA approach to the case project of the paper. The findings of the paper suggest that the EA is applicable to CD&E work, although all aspects of the original concept could not be expressed in the EA model of the case project. The results also show that the SiME method can support in applying the EA framework to the CD&E in the case project.

Developing of Supportive Context for Eco-Industrial Networks in Finland

The aim of the present thesis was to explore possible promotional actions to support the emergence of eco-industrial business networks in Finland. The main objectives were to investigate what kind of factors affect in the development of eco-industrial networks and further make suggestions in what kinds of actions this could be supported. In addition, since the active facilitation was discovered as one potential promoting activity, further investigation about facilitation process in Finnish context was conducted and also main characteristics of nationwide facilitation programme were identified. This thesis contains literature review of network orchestration and eco-industrial networks. The latter consists of green supply chain management and industrial symbiosis, although the main focus of the study leans on the concept of industrial symbiosis. The empirical data of the study was obtained from semi-structured expert interviews. These interviews were analyzed using qualitative content analysis. The study identified four main promotional activities for eco-industrial networks: 1) building awareness, 2) incentives, 3) dismantling of legislative barriers and 4) active facilitation. In addition, a framework for facilitation activities in Finnish context was built and main characteristics of nationwide facilitation programme were identified.
