MSW: from pollution/degradation source to resource

Municipal Solid Waste is one of the biggest challenges that cities are facing: MSW is considered of the main sources of energy consumption, urban degradation and pollution. This paper defines the major negative effects of MSW on cities and proposes new solutions to guide waste policies. Most contemporary waste management efforts are focused at regional government level and based on high tech waste disposal by methods such as landfill and incineration. However, these methods are becoming increasingly expensive, energy inefficient and pollutant: waste disposal is not sustainable and will have negative implications for future generations. In this paper are proposed all the principle solutions that could be undertaken. New policy instruments are presented updating and adapting policies and encouraging innovation for less wasteful systems. Waste management plans are fundamental to increase the ability of urban areas effectively to adapt to waste challenges. These plans have to give an outline of waste streams and treatment options and provide a scenario for the following years that significantly reduce landfills and incinerators in favor of prevention, reuse and recycling. The key aim of an urban waste management plan is to set out the work towards a zero waste economy as part of the transition to a sustainable economy. Other questions remain still opened: How to change people’s behavior? What is the role of environmental education and risk perception? It is sure that the involvement of the various stakeholders and the wider public in the planning process should aim at ensuring acceptance of the waste policy.

Is there hope for BNF in common beans?

Although since 1984 there are Rhizobium strains available for common bean inoculation in Brazil, a survey in 2014 showed that only 15% of the Brazilian farmers adopt inoculation as a routine practice. Part of this disbelief in relation to common beans inoculation can be attributed to the fact that supposedly, bean inoculation would not be able to support increased yield levels in high-tech farms, being appropriate only for small farms. A series of demonstration units carried out since 2012, under farm conditions in the Cerrado region, have showed that a 10.8% mean increase in yield were obtained only with inoculation in relation to the treatment without inoculation and without nitrogen fertilization (whose average yield was 3163 kg ha-1). It was also found that inoculation with supplementation of 60 kg ha-1 of N promoted yield levels (4010 kg ha-1) higher than those with 120 kg ha-1 N as urea (3411 kg ha-1).

DIDÁCTICA DE LA GEOGRAFÍA Y DIDÁCTICA SUPERIOR

El artículo reflexiona sobre el aporte de la didáctica en el proceso de enseñanza – aprendizaje, enfatizando en su carácter teórico – práctica.  Diferencia entre una didáctica general y una didáctica específica.La Didáctica Crítica propone al profesor en Geografía como un maestro en el  saber y actuar, en el cumplimiento de sus deberes, responsabilidades y habilidades.  La enseñanza de la Geografía precisadel apoyo de numerosos instrumentos de alta tecnología, que constituyen valiosos aportes didácticos, la  incorporación de  las Tecnologías de  Información y Comunicación  (TICʼs)    es una necesidad. La formación a nivel universitario debe ofrecer las destrezas  y habilidades en la creación y composiciónde medios audiovisuales para la enseñanza  de la Geografía.  La Geografía contribuye eficazmente al desarrollo de capacidades, actitudes y competencias genéricas esenciales sobre las que ha de basarse la formación ciudadana y la educación de valores.Palabras claves: Geografía, didáctica de  la Geografía, saber geográfico, metodología de enseñanza, método didáctico.AbstractThe article reflects on the contribution from didactics in the process of teaching-learning, emphasizing in its theoretical character – practice. It differentiates between general didactics and specific didactics. Critical didactics suggests that the Geography professor, as an expert, knows and acts according to his or her duties, responsibilities and abilities.The teaching of the Geography draws upon the support of high-tech tools, which constitute valuable didactic contributions, so that incorporation of the Technology Information and Communication (TICʼs) is a necessity to be the mode of communication. Formation at the university level ought to offer talents and abilities in the creation and composition of audio-visual media in the teaching of geography. Geography effectively contributes to development of capabilities, attitudes and competencies generic essential for citizen formation and the education of values.Key Words: Geography,  didactics  of Geography,  geographical  knowledge,  teaching methodology, didactic method

Human rights performance disclosure by companies having operations in high risk countries: Evidence from Australian mineral sector

The aim of this study is to explore whether Australian mineral companies operating in high human rights risk countries provide more human rights disclosures than companies operating in low risk countries. A content analysis instrument containing 88 specific human rights performance items derived from a number of international human rights guidelines has been developed to investigate the annual reports, social responsibility reports and corporate websites of the top 50 Australian mineral companies (2010/2011). The findings show that human rights performance disclosures by companies with operations in high human rights risk countries are significantly higher than companies with operations in the low risk countries. By disclosing extended human rights performance information, companies operating in high risk countries appear to ease community concerns about human rights violations. The finding is consistent with legitimacy theory which posits that organisations respond to community concerns in relation to particular social issues.

The adjustment of leadership styles in intercultural workplace – some evidences from the multinational construction companies in Hong Kong

This study investigates the existence of intercultural adjustment in the multicultural construction workplaces by examining the leadership orientations (task-/people-orientation), communication and conflict resolution skills (high/low-context culture), and power relationship styles (high/low power distance) of local Chinese and the British expatriate project managers in the multinational construction companies in Hong Kong. A sample of project managers (N = 40) and their subordinates (N = 61) were surveyed using the structured questionnaires. Statistical techniques (independent-samples t-test, and Pearson correlation analysis) were employed to evaluate the data. The results revealed a number of interesting findings. First, it was found that both project manager groups equally considered the importance of task performance and interpersonal relationship. The results of correlations analysis provide support for the linkages of the length of working abroad with the change in task/people orientation for Chinese and expatriate managers. The analysis revealed that those Chinese managers who have the longest length of time living or working in Western countries tended to measure higher on task-orientation. Similarly, those British expatriate managers who have the longest period of working in Hong Kong tended to be less task-orientated. Second, local Chinese managers were found to be more confrontational when they strongly disagree with their team members than their British expatriate counterparts. It would appear that stress from project deadline which increase the directness and terseness in communication acts, and retain the composure of project managers in dealing with the subordinates. Finally, our findings show that there is significant difference between local Chinese and British expatriate managers in their power relationship with subordinates. This implies that although the intercultural adjustment might influence perceptions of local and expatriate managers, some dominant deep-rooted cultural values and beliefs are still not easily altered. Conclusions are presented along with suggestions for future studies.

The challenges of participatory research with ‘tech-savvy’ youth

This paper focuses on participatory research and how it can be understood and employed when researching children and youth. The aim of this paper is to provide a theoretically and empirically grounded discussion of participatory research methodologies with respect to investigating the dynamic and evolving phenomenon of young people growing up in networked societies. Initially, we review the nature of participatory research and how other researchers have endeavoured to involve young people (children and youth) in their research projects. Our review of these approaches aims to elucidate what we see as recurring and emerging issues with respect to the methodological design of involving young people as co-researchers. In the light of these issues and in keeping with our aim, we offer a case study of our own research project that seeks to understand the ways in which high school students use new media and network ICT systems (Internet, mobile phone applications, social networking sites) to construct identities, form social relations, and engage in creative practices as part of their everyday lives. The article concludes by offering an assessment of our tripartite model of participatory research that may benefit other researchers who share a similar interest in youth and new media.
