The evolution of the car-making industry

Mass-production, cars, pollution – they all have long become well known and well connected phenomena of the modern life. Nowadays the people can also add to the list such items like awareness, scientific approach, long-term thinking, and environmental responsibility. They are surrounded by a multitude of consumer goods, most of which are produced in a scientific manner, and all of which will more sooner than later end up in the garbage. Cars are the most noticeable – both by size and by numbers – and also the most expensive of all the mass products in people’s view. For many of them they are a clear target for reprimand and regulation, and, as a result, the automotive industry is being increasingly brought under bureaucratic control, together with its whole supplier and distributor network. The author started writing this article in an attempt to place the above process under scrutiny, because it is his firm belief that similar measures, similar tough governmental control will inevitably spill over to other industries, which at the moment are producing more inconspicuous, but still polluting products. The present paper shows the relationship between car-making, supply chain management and the efforts of public administration to protect the environment – a connection with clear practical implications.

Responsibility for the Future

Responsibility for the future can be closely linked to innovation and responsibility of entrepreneurship, nevertheless we are all responsible for our future. Since futurists have a special role in catalysing social changes and channelling actions for better futures, the present study analyses how the responsibility of futurists is seen in our times, characterised by great and far-reaching changes, and how this activity is enriched by elements of foresight. The responsibility of futurists lies in mapping out, communicating and implementing future alternatives. Futurists also have considerable responsibility to convince people that essential changes have to be accepted by the public.

Tropical seagrass-associated macroalgae distributions and trends relative to water quality

Tropical coastal marine ecosystems including mangroves, seagrass beds and coral reef communities are undergoing intense degradation in response to natural and human disturbances, therefore, understanding the causes and mechanisms present challenges for scientist and managers. In order to protect our marine resources, determining the effects of nutrient loads on these coastal systems has become a key management goal. Data from monitoring programs were used to detect trends of macroalgae abundances and develop correlations with nutrient availability, as well as forecast potential responses of the communities monitored. Using eight years of data (1996–2003) from complementary but independent monitoring programs in seagrass beds and water quality of the Florida Keys National Marine Sanctuary (FKNMS), we: (1) described the distribution and abundance of macroalgae groups; (2) analyzed the status and spatiotemporal trends of macroalgae groups; and (3) explored the connection between water quality and the macroalgae distribution in the FKNMS. In the seagrass beds of the FKNMS calcareous green algae were the dominant macroalgae group followed by the red group; brown and calcareous red algae were present but in lower abundance. Spatiotemporal patterns of the macroalgae groups were analyzed with a non-linear regression model of the abundance data. For the period of record, all macroalgae groups increased in abundance (Abi) at most sites, with calcareous green algae increasing the most. Calcareous green algae and red algae exhibited seasonal pattern with peak abundances (Φi) mainly in summer for calcareous green and mainly in winter for red. Macroalgae Abi and long-term trend (mi) were correlated in a distinctive way with water quality parameters. Both the Abi and mi of calcareous green algae had positive correlations with NO3−, NO2−, total nitrogen (TN) and total organic carbon (TOC). Red algae Abi had a positive correlation with NO2−, TN, total phosphorus and TOC, and the mi in red algae was positively correlated with N:P. In contrast brown and calcareous red algae Abi had negative correlations with N:P. These results suggest that calcareous green algae and red algae are responding mainly to increases in N availability, a process that is happening in inshore sites. A combination of spatially variable factors such as local current patterns, nutrient sources, and habitat characteristics result in a complex array of the macroalgae community in the seagrass beds of the FKNMS.

Corporate Responsibility on a "Grand" Scale: MGM's Employment Outreach Program

The world's largest hotel, casino, and theme park has demonstrated that corporate responsibility to the community and corporate self-interest need not be mutually exclusive. MGM's human resource department established an employment outreach program that hired 1,462 economically disadvantaged persons from the community. This effort was a "win-win" situation for the both the community and the corporation and the hotel received a significant wage credit from the Job Training Partnership Act.

The Foodservice Industry's Social Responsibility Regarding the Obesity Epidemic, Part II: Incorporating Strategic Corporate Social Responsibility into Foodservice Operations

Just as all types of business firms are now expected to go beyond their profit-oriented activities in boosting the well-being of the community, so, too, is corporate social responsibility (CSR) expected from foodservice firms. The significance of the obesity epidemic, combined with the foodservice industry's role in the development of this epidemic, suggests that the industry has an ethical responsibility to implement CSR activities that will help reduce obesity, particularly among children. CSR should be seen as an efficient management strategy through which a firm voluntarily integrates social and environmental concerns into its business operations and its interactions with stakeholders. Although costs are associated with CSR initiatives, benefits accrue to the firm. Decisions regarding alternative CSR activities should be based on a cost-benefit analysis and calculation of the present value of the revenue stream that can be identified as resulting from the specific CSR activities. CSR initiatives should be viewed as long-term investments that will enhance the firms’ value. Key areas for foodservice firms' CSR activities include marketing practices, particularly practices impacting advertising to children and marketing that will enhance the firms’ visibility; portion-size modification; new-product development; and consistent nutrition labeling on menus.

Land Use and Climate Change Impacts on the Hydrology of the Upper Mara River Basin, Kenya: Results of a Modeling Study to Support Better Resource Management

Some of the most valued natural and cultural landscapes on Earth lie in river basins that are poorly gauged and have incomplete historical climate and runoff records. The Mara River Basin of East Africa is such a basin. It hosts the internationally renowned Mara-Serengeti landscape as well as a rich mixture of indigenous cultures. The Mara River is the sole source of surface water to the landscape during the dry season and periods of drought. During recent years, the flow of the Mara River has become increasingly erratic, especially in the upper reaches, and resource managers are hampered by a lack of understanding of the relative influence of different sources of flow alteration. Uncertainties about the impacts of future climate change compound the challenges. We applied the Soil Water Assessment Tool (SWAT) to investigate the response of the headwater hydrology of the Mara River to scenarios of continued land use change and projected climate change. Under the data-scarce conditions of the basin, model performance was improved using satellite-based estimated rainfall data, which may also improve the usefulness of runoff models in other parts of East Africa. The results of the analysis indicate that any further conversion of forests to agriculture and grassland in the basin headwaters is likely to reduce dry season flows and increase peak flows, leading to greater water scarcity at critical times of the year and exacerbating erosion on hillslopes. Most climate change projections for the region call for modest and seasonally variable increases in precipitation (5–10 %) accompanied by increases in temperature (2.5–3.5 °C). Simulated runoff responses to climate change scenarios were non-linear and suggest the basin is highly vulnerable under low (−3 %) and high (+25 %) extremes of projected precipitation changes, but under median projections (+7 %) there is little impact on annual water yields or mean discharge. Modest increases in precipitation are partitioned largely to increased evapotranspiration. Overall, model results support the existing efforts of Mara water resource managers to protect headwater forests and indicate that additional emphasis should be placed on improving land management practices that enhance infiltration and aquifer recharge as part of a wider program of climate change adaptation.

Planejando com lean construction: diretrizes para implementação da construção enxuta em obras

Nowadays lives up in an era of tight credit caused by the global financial crisis, as occurred in the past, it is the responsibility of various sectors and segments of society find ways to reinvent itself. In this context, Lean Construction presents itself as a strong alternative production management for companies in the construction segment. Arising out of lean thinking that originated in Japan in the postwar period and has spread around the world in times of extreme scarcity with the oil crisis. In practice the Lean Construction is a philosophy that seeks to improve the process of production management, maximizing the value of the flow from the customer's perspective through the elimination of losses. And thrives in environments and cultures that consider the scarcity of resources like something natural, applying both the macroeconomic crisis as in times of prosperity. The Planning and Production Control - PCP presents itself as a fundamental building block for companies to protect themselves in the face of economic fluctuations, seeking for their survival and success in the competitive market. Motivated by the lack of discussion of the topic in the local academy, and for the identification of 93.33% of construction companies that do not make use of methodological tools for PCP in the state, this dissertation aims to study and propose the implementation of lean construction in methodology of planning projects implemented on construction sites. This characterized the management system, of the production of a construction company, pointing out the main causes of ineffectiveness related to consequent low performance of one of his ventures. In sequence, the PCP was implemented with the use of tools to serve the principles of lean construction. This being monitored through indicators that provided managers managerial view of process of actions control and production of protective mechanisms. All implementation guidelines and application of this management model, were exposed in a simplified way, practical and efficient, in order to break the resistance of new practices and old paradigms in the industry.

Minimization of radiation exposure due to computed tomography in inflammatory bowel disease

Patient awareness and concern regarding the potential health risks from ionizing radiation have peaked recently (Coakley et al., 2011) following widespread press and media coverage of the projected cancer risks from the increasing use of computed tomography (CT) (Berrington et al., 2007). The typical young and educated patient with inflammatory bowel disease (IBD) may in particular be conscious of his/her exposure to ionising radiation as a result of diagnostic imaging. Cumulative effective doses (CEDs) in patients with IBD have been reported as being high and are rising, primarily due to the more widespread and repeated use of CT (Desmond et al., 2008). Radiologists, technologists, and referring physicians have a responsibility to firstly counsel their patients accurately regarding the actual risks of ionizing radiation exposure; secondly to limit the use of those imaging modalities which involve ionising radiation to clinical situations where they are likely to change management; thirdly to ensure that a diagnostic quality imaging examination is acquired with lowest possible radiation exposure. In this paper, we synopsize available evidence related to radiation exposure and risk and we report advances in low-dose CT technology and examine the role for alternative imaging modalities such as ultrasonography or magnetic resonance imaging which avoid radiation exposure.

The Use of Agricultural Chemicals and Mosquito Response to Pyrethroids in Bungoma Sub-county,Western Kenya

Insecticide treated bed nets and indoor residual spraying are the most widely used vector control methods in Africa. The World Health Organization now recommends four classes of insecticides for use against adult mosquitoes in public health programs. Of these four classes of insecticides, pyrethroids have become the insecticides of choice in treating mosquito bed nets and in the use of indoor spraying to prevent malaria transmission. Pyrethroids are not only used in malaria control but also in agriculture to protect against pest insects. This concurrent use of pyrethroids in vector control and protection of crops from pests in agriculture may exert selection pressure on mosquito larval population and induce resistance to this class of insecticides. The main objective of our study was to explore the role of agricultural chemicals and the response of mosquitoes to pyrethroids in an area of high malaria transmission.

We used a cross-sectional study design. This was a two-step study involving both mosquitoes and human subjects. In this study, we collected larvae growing in breeding sites affected by different agricultural practices. We used purposive sampling to identify active mosquito breeding sites and then interviewed households adjacent to those breeding sites to learn about their agricultural practices that might influence the response of mosquitoes to pyrethroids. We also performed secondary analysis of larval data from a previous case-control study by Obala et al.

To speak or not to speak English during English lessons : A literature study on language use in the elementary classroom

There are different views regarding which language should be used in the second language classroom. Therefore, the aim of this literature review is to find out if the teachers’ choice of language use in the classroom can affect the students’ motivation to speak English and if there are other factors that can affect the teachers’ choice of language use. This study is based on six different sources who all have investigated the use of the first language and/or the target language in schools in different parts of the world. The results of this study show that both the use of the first language and the target language can affect the students’ motivation to speak English. The results also show that there are many different factors that can affect the teachers’ choice of language in the classroom, apart from motivation. These factors include the use of the first or the target language to ensure comprehension, encourage communication, create and maintain relationships between teachers and students, keep up a good classroom climate, and to uphold discipline. There are arguments both for using the first language and the second language in the second language classroom and it is difficult to determine which language is the best to use. However, what can be determined is that it is the teachers’ responsibility to decide and to have a reason for choosing one language or the other.

SMEs Attitudes to “Information Assurance” and Consequences for the Digital Single Market

It is now generally accepted that cyber crime represents a big threat to organisations, and that they need to take appropriate action to protect their valuable information assets. However, current research shows that, although small businesses understand that they are potentially vulnerable, many are still not taking sufficient action to counteract the threat. Last year, the authors sought, through a more generalised but categorised attitudinal study, to explore the reasons why smaller SMEs in particular were reluctant to engage with accepted principles for protecting their data. The results showed that SMEs understood many of the issues. They were prepared to spend more but were particularly suspicious about spending on information assurance. The authors’ current research again focuses on SME attitudes but this time the survey asks only questions directly relating to information assurance and the standards available, in an attempt to try to understand exactly what is causing them to shy away from getting the badge or certificate that would demonstrate to customers and business partners that they take cyber security seriously. As with last year’s study, the results and analysis provide useful pointers towards the broader business environment changes that might cause SMEs to be more interested in working towards an appropriate cyber security standard.

Corporate Social Responsibility no sector bancário

Vivemos num mundo globalizado onde as exigências são diversas e constantemente presentes. É impossível analisar a área social, económica ou ambiental de forma isolada. A visão que relaciona o mundo empresarial com a sociedade e que lhe reconhece obrigações e responsabilidades para com a mesma não é nova e tem vindo a obter uma importância e visibilidade crescentes. O conceito corporate social responsibility (CSR) tem sido objecto de grande enfoque, sobretudo desde os anos cinquenta do século passado. Todavia, este conceito não tem permanecido inalterado com o passar do tempo. Desde a referida década até à actualidade verifica-se um desenvolvimento notório da definição de CSR, das suas vertentes, do binómio mundo empresarial e social e de alguns conceitos conexos como sejam corporate citizenship, business ethics e sustainability. Actualmente a maioria da doutrina que versa sobre o tema aceita, de forma pacífica, que o mundo empresarial não se pode fechar sobre si próprio pretendendo alcançar ganhos e visibilidade demitindo-se da responsabilidade para com a sociedade onde se encontra inserido. Compreende-se que a interligação entre a esfera económica, social e ambiental permite às empresas diversos benefícios, nomeadamente a viabilização de projectos a longo prazo, prestígio, notoriedade e a vantagem competitiva face às suas concorrentes. O objectivo do presente trabalho é demonstrar a evolução do conceito de CSR, nas suas várias vertentes, o impacto e os benefícios decorrentes das actuações empresarias compatíveis com este conceito e verificar, no que ao sector bancário respeita, se os clientes destas instituições conhecem os projectos sociais, pelas mesmas desenvolvidos e se a realização destes projectos possuem impacto na relação cliente/banco.

Genetic manipulation of Anopheles stephensi immunity to increase plasmodium falciparum salivary gland sporozoite infection levels

Human malaria is responsible for over 700,000 deaths a year. To stay abreast of the threat posed by the parasite, a constant stream of new drugs and vector control methods are required. This study focuses on a vaccine that has the potential to protect against parasite infection, but has been hindered by developmental challenges. In malaria prevention, live, attenuated, aseptic, Plasmodium falciparum sporozoites (PfSPZ) can be administered as a highly protective vaccine. PfSPZ are produced using adult female Anopheles stephensi mosquitoes as bioreactors. Production volume and cost of a PfSPZ vaccine for malaria are expected to be directly correlated with Plasmodium falciparum infection intensity in the salivary glands. The sporogonic development of Plasmodium falciparum in A. stephensi to fully infected salivary gland stage sporozoites is dictated by the activities of several known components of the mosquito’s innate immune system. Here I report on the use of genetic technologies that have been rarely, if ever, used in Anopheles stephensi Sda500 to increase the yield of sporozoites per mosquito and enhance vaccine production. By combining the Gal4/UAS bipartite system with in vivo expression of shRNA gene silencing, activity of the IMD signaling pathway downstream effector LRIM1, an antagonist to Plasmodium development, was reduced in the midgut, fat body, and salivary glands of A. stephensi. In infection studies using P. berghei and P. falciparum these transgenic mosquitoes consistently produced significantly more salivary gland stage sporozoites than wildtype controls, with increases in P. falciparum ranging from 2.5 to 10 fold. Using Plasmodium infection assays and qRT-PCR, two novel findings were identified. First, it was shown that 14 days post Plasmodium infection, transcript abundance of the IMD immune effector genes LRIM1, TEP1 and APL1c are elevated, in the salivary glands of A. stephensi, suggesting the salivary glands may play a role in post midgut defense against the parasite. Second, a non-pathogenic IMD signaling pathway response was observed which could suggest an alternative pathway for IMD activation. The information gained from these studies has significantly increased our knowledge of Plasmodium defense in A. stephensi and moreover could significantly improve vaccine production.
