The present research seeks to extend existing theory on self-disclosure to the online arena in higher educational institutions and contribute to the knowledge base and understanding about the use of a popular social networking site (SNS), Facebook, by college students. We conducted a non-experimental study to investigate how university students (N = 463) use Facebook, and examined the roles that personality and culture play in disclosure of information in online SNS-based environments. Results showed that individuals do disclose differently online vs. in-person, and that both culture and personality matter. Specifically, it was found that collectivistic individuals low on extraversion and interacting in an online environment disclosed the least honest and the most audience-relevant information, as compared to others. Exploratory analyses also indicate that students use sites such as Facebook primarily to maintain existing personal relationships and selectively used privacy settings to control their self-presentation on SNSs. The findings of this study offer insight into understanding college students' self-disclosure on SNS, add to the literature on personality and self-disclosure, and shape future directions for research and practice on online self-presentation. © 2012 Elsevier Ltd.

Higher sales and margins are key goals for retailers promoting emerging products, such as organics, but little is known about their marketing effectiveness and their cross-effects on conventional product sales. Extant research reports conflicting results about price and promotional sensitivity for organic products and does not address the impact of organic assortment. This article calculates long-term own- and cross-elasticities of organic and conventional product sales in response to changes in assortment, price, and promotions. Using a rich data set of 56 categories, the authors test hypotheses on how different costs and benefits of organic products affect these elasticities. They find that enduring actions, such as assortment and regular price changes, have a higher elasticity for organics than for conventional products. In contrast with common wisdom, even "core" organic consumers are sensitive to these actions. Increasing organic assortment and promotion breadth yields higher profits for the total category, as do more frequent promotions on conventional products. The category comparison yields specific advice with regard to where larger assortment and lower prices versus more and deeper promotions are most effective. © 2013, American Marketing Association.

NEED4B aims to develop an open and easily replicable methodology for designing, constructing, and operating new low energy buildings, aiming to a large market uptake. The NEED4B methodology will be validated and refined by a strong demonstration programme, envisaging the construction of 27.000 square meters, spread among five different climatic zones, buildings types and uses. The weighted average of energy consumption in the demo sites, on primary energy, is 43 kWh/m2year, representing a 65% of reduction compared with the current regulation and regular practice. The weighed average of CO2 emissions is 1,91 kg/m2year, corresponding to a of 94% reduction compared to the current national regulations and regular practices. The total emissions avoided by the five demo sites are 831,9 tCO2/year. The proposed methodology will integrate tools and procedures that already exist or are under development, like Integrated Project Delivery, Building Information Modelling, Life Cycle Assessment, Life Cycle Cost and simulation softwares, providing recommendations and guidelines, adapted to the different type of stakeholders (investors, promoters, owner, users, architects, contractors, public authorities, SMEs, etc.) for the whole construction process. NEED4B will be part of an ambitious initiative that will totally invest 191 M and involve around 46.000 person months for the design, construction and monitoring of the demo sites. The requested EC contribution (5,7 M grant and 590 persons months) will help to leverage these resources, obtaining an exemplary coordinated EU low energy buildings demonstration, with high replication potential due to the associated methodology, and a relevant visibility. The weighted average energy savings are 60 kWh/m2year, resulting in reduction of the bill of 9,6 /m2year. The weighted average cost for each kWh reduced is 0,81 / m2year, and the weighted average cost for each kgCO2 avoided is of 3,5 / m2year.

TRIBE project aims to contribute to a citizens behaviour change towards energy efficiency in public buildings, through their engagement in the experience of playing a social game, linked by ICT to real time data collected from 5 pilot buildings hosting around 1.300 regular users (employees, tenants) and almost 12.000 eventual users (visitors). The targeted average energy savings in the pilots is 24,8% of the current energy consumption. TRIBE project will carry out serious game aims to engage more than 750.000 players by the end of the project, involving users of the targeted pilot facilities and their social networks. As a result of the analysis and developments accomplished using the pilot cases of the TRIBE project, and in addition to the game that will serve to collect all the relevant information, a whole and very broad number of tools and guidelines named TRIBE pack will be set up to be used by public building tenants and owners. The goal is foster the spread of the public building users behaviour change as well as to support the deployment of ICTs for energy efficiency among public building owners and operators. The content of the final TRIBE pack will include; (1) an initial energy audit and diagnosis, (2) the development of a virtual pilot in conformity with the image of their real buildings, (3) an adapted ICT for energy efficiency deployment plan, (4) a funding scheme merging existing instruments with clean web solutions and (5) a user engagement campaign addressing the specific behaviour change challenges.

A scalable, replicable, high energy efficient, zero emissions and cost effective SYSTEM to refurbish existing public-owned non-residential buildings to achieve at least 50% energy consumption reduction through: a) A systemic methodology for optimal building retrofitting towards zero emissions, developed to ensure cost effectiveness, scalability and replicability of the interventions taking into account external (geographical, climatic, resources, social) and internal (envelope, facilities and use) building boundary conditions. b) Development of demand reduction strategies: Based on envelope U-value improvement through innovative technologies, material applications and design techniques. c) Development of Energy reduction strategies: An effective interaction and integration of an innovative, scalable, high efficient renewable HVAC hybrid cogeneration system fed with locally available RES, including thermal energy storage strategies as the core of the methodologys implementation. d) Effective interactions of energy flows: building to building, building to electrical grid and building to heating and cooling networks and improved methodologies for interconnectivity of smart grids and heating and cooling networks under the control of a building level energy operation system. Buildings will be considered as single energy-consumption units and at the same time, connected to other buildings forming high energy efficient districts prepared to be connected with other districts around. These energy units will be able to provide advanced energy services (electrical and thermal) to other buildings in their district, which will make the building strategies replicable al district level in order to attract investments.0
