This paper aims to reinforce the arguments for applying the social support concept in social marketing.

This paper aims to conceptually outline the potential positive contribution of social support for social marketing practice as a tool to induce behavior change.

This paper focuses on the philosophical principle of social exchange, highlights the consumer-centered perspective of social marketing, which implies the natural evaluation of the social networks of influence and support and presents social support as a mechanism to induce long-term behavior change.

No empirical (qualitative or quantitative) investigations were used to test the application of the concept in practical interventions.

This paper provides significant insights for intervention developers that can be used to program and theoretically justify future social marketing interventions applying the social support concept.

Empirical research concluded for a positive relation between social support and human health and well-being. Thus, increasing the use of the concept in social marketing can serve to attain these social goals.

The concept of social support has gained considerable interest in the areas of behavioral medicine and health psychology. Despite such interest, it is still not clear how it can be approached in social marketing as there is a lack of conceptual literature discussing social support from a social marketing perspective, the number of social marketing interventions operationalizing the concept is limited and, till date, no research has focused in comprehensively establishing a theoretical rationale to operationalize the concept in social marketing.

How does social capital matter to the creation of neighbourhood networks in cities? Social housing in Portugal is some times viewed as a single architectural and building environment development failure. This article discusses a relevant Portuguese urban planning landscape and aims to contribute to the discussion of one of its main purpose – the social housing experiment. The author discusses the case of this landscape as urban policy-making and evaluates its implementation and relevance. She hypothesizes that “neighbourhood units” have become a relevant case in the context of neighbourhood planning and housing social-mix in Lisbon. Firstly, she uses theoretical arguments and findings to discuss an urban experiment - Alvalade Landscape. Secondly, the paper analyses relevant data that demonstrates its links to the housing policies thus enriching the urban design. The article offers evidence from the Alvalade Landscape case study in Lisbon of theoretical and empirical community ties in the 1940s. Thirdly, the paper identifies some elements such as community units, social mix, sidewalks, and that have an impact on neighbourhood design as well as people’s lives. The findings show that supportive neighbour ties provide important network resources (social capital) concerning daily life, illness, support or financial aid. Finally, the paper suggests the relevance that social neighbourhood community has in housing programs and policies.

This study aims to embed anatase, rutile and brookite TiO₂ nanoparticles (NPs) with different crystal phases into cotton fabrics by epoxy silane and to examine the effect of these applications on the photocatalytic and mechanical properties of the fabric.

Different aqueous dispersions which contain anatase, rutile and brookite were prepared at three different concentrations (5%, 10% and 15%). These NPs were embedded in cotton fabrics by using GPTS [(3-glycidyloxypropyl) trimethoxysilane]. Characterization tests were performed by scanning electron microscopy (SEM), Raman and Fourier-transform infrared spectroscopy (FT/IR). Samples were stained with methylene blue (MB) and then exposed to solar light for different periods. Color changes of the samples were examined with a spectrophotometer. Air permeability, abrasion and tear strength tests were applied to all samples.

According to SEM images, the NPs were successfully attached to the cotton fabrics, and epoxy silane coating surrounded the fiber surfaces. The presence of the coating was also confirmed by Raman spectroscopy and FT/IR. The treatments reduced the stainability of the samples. The most effective applications for ensuring photocatalytic activity in cotton fabrics were suspensions as 10% brookite, 10% anatase and 5% anatase, in descending order. The applied coating slightly reduced the samples’ air permeability, and wear and tear strength.

The importance of this study is to determine the optimal crystal phase and its concentration by using epoxy silane to ensure self-cleaning properties on cotton fabrics. The sample treated with 10% brookite is the most approached its original white color by 99.65% as a result of degradation of MB (after 120 min). On the other hand, using the pure rutile with epoxy silane was not suitable for removing MB from the fabric.

The purpose of this study is to analyze the systematic relationships among dynamic capabilities in startups’ survival.

This study is based on a systematic literature review on dynamic capabilities related to startups’ survival, following the content analysis approach.

This study presents four different perspectives of analysis about dynamic capabilities from resources exchange and business factors that meet needs of startups' survival. It also points out new area for future research in this field. In doing so, this study differentiates itself by its approach not limiting dynamic capabilities research and enriching entrepreneurs' capability theory.

By indicating an evolution of dynamic capabilities theory among tangible and intangible resources exchange in a more favorable adaptation to startups growth, this study boosters and contributes to the society, economy in general and to the science of business management in various perspectives such as overcoming cognitive barriers, entrepreneur’s commitment, innovation capabilities and knowledge capacity of startups.

This study amplifies dynamic capabilities vision in startups’ survival as one of the main sources for growth in this type of organizations. It also develops a deeper understanding about new avenues for dynamic capabilities theory among tangible and intangible resources exchange.

The role of information technology (IT) in the business arena has continuously shifted over the last decades, and it has become an important part of how companies manage and control their resources. User satisfaction in IT usage is critical because this construct is often viewed as a surrogate for IT success. Decisions regarding the building of the technical IT architecture should be closely linked to the organizational design of the company itself. So, IT plays a crucial role in organization, especially regarding the accounting function.

The purpose of this paper is to contribute to the body of knowledge in the extent to which IT affects the ability to solve accounting tasks. We will measure the impact of IT on user satisfaction, on accounting information use and, finally, on accountants' tasks.

The relationship between IT and management accounting practices was investigated. On one hand, data from Portuguese manufacturing firms were collected using a survey and analyzed using statistical software. On the other hand, based on findings from 17 in-depth interviews, 6 case studies were built and analyzed.

The findings suggest that user satisfaction in IT usage and the use of accounting techniques and accounting information increases with new IT investments. We also find a tendency for change in the decentralization of management accounting tasks.

These study findings have significant implication for practice and research. Today accounting and IT are inseparable and accountant's uses of sophisticated management accounting techniques are clearly dependent of IT existence.
