Community formation among Asian Indians in southeast Florida

Nearly one million Asian Indians have immigrated to the United States. Asian Indians are scattered across wide geographic areas. While some have chosen transnationalism, most are taking the traditional route of building ethnic communities. Using what the West has to offer in terms of communication and transportation technologies, they are constructing communities without geographic boundaries, with the extensive use of the automobile and air transportation, cellular phones, FAX machines, commercial delivery services, multi-party conference phones. Also, they are incorporating the American tradition of immigrant associations into an Asian Indian syncretism of community. In the process there emerges an Asian Indian identity and concept of kinship and community. ^

A fresh look at decision making in international investment choices: Firm international coherence and home-host country relatedness

Understanding how decisions for international investments are made and how this affects the overall pattern of investments and firm’s performance is of particular importance both in strategy and international business research. This dissertation introduced first home-host country relatedness (HHCR) as the degree to which countries are efficiently combined within the investment portfolios of firms. It theorized and demonstrated that HHCR will vary with the motivation for investments along at least two key dimensions: the nature of foreign investments and the connectedness of potential host countries to the rest of the world. Drawing on cognitive psychology and decision-making research, it developed a theory of strategic decision making proposing that strategic solutions are chosen close to a convenient anchor. Building on research on memory imprinting, it also proposed that managers tend to rely on older knowledge representation. In the context of international investment decisions, managers use their home countries as an anchor and are more likely to choose as a site for foreign investments host countries that are ‘close’ to the home country. These decisions are also likely to rely more strongly on closeness to time invariant country factors of historic and geographic nature rather than time-variant institutions. Empirical tests using comprehensive investments data by all public multinational companies (MNC) worldwide, or over 15,000 MNCs with over half a million subsidiaries, support the claims. Finally, the dissertation introduced the concept of International Coherence (IC) defined as the degree to which an MNE’s network comprises countries that are related. It was hypothesized that maintaining a high level of coherence is important for firm performance and will enhance it. Also, the presence of international coherence mitigates some of the negative effects of unrelated product diversification. Empirical tests using data on foreign investments of over 20,000 public firms, while also developing a home-host country relatedness index for up to 24,300 home-host pairs, provided support for the theory advanced.

Commuter Airlines:Their Changing Role

In - Commuter Airlines: Their Changing Role – an essay by J. A. F. Nicholls, Transportation Coordinator, Department of Marketing and Environment, College of Business Administration, Florida International University, Nicholls initially observes: “The great majority of airline passenger miles flown in the United States are between large conurbations. People living in metropolitan areas may be quite unaware of commuter airlines and their role in our transportation system. These airlines are, however, communications lifelines for dwellers in small - and not so small - towns and rural areas. More germanely, commuter airlines have also developed a pivotal role vis-a-vis the major carriers in this country. The author discusses the antecedents of the commuter Airlines, their current role, and future prospects.” Huh; conurbations? Definition: [n.] a large urban area created when neighboring towns spread into and merge with each other In providing a brief history on the subject of commuter airlines, Nicholls states: “…there had been a sort of commuter airline as far back as 1926 when, for example, the Florida Airways Corporation provided flights between Jacksonville and Atlanta, Colonial Air Lines between New York and Boston, and Ford Air Transport from Detroit to Cleveland.” “The passage of the Civil Aeronautics Act in 1938 was pivotal in encouraging and developing a passenger orientation by the airlines…” Nicholls informs you. Nicholls provides for the importance of this act by saying: “The CAA was empowered to act “in the public interest and in accordance with the public convenience and necessity.” Only the CAA itself could determine what constituted the “public convenience and necessity.” Nobody, however, could provide air transportation for public purposes without a Certificate of Public Convenience and Necessity, dispensed by the CAA.” The author wants you to know that this all happens in the age of airline regulation; that is to say, pre de-regulation i.e. 1978. Airlines could not and did not act on their own behalf; their actions were governed by the regulating agency, that being the Civil Aeronautics Board [CAB], who administered the conditions set forth by the CAA. “In 1944 the CAB introduced a new category of service called feeder airlines to provide local service-short-haul, low density-for smaller communities. These carriers soon became known as air taxis since they operated as common carriers, without a regular schedule,” says Nicholls in describing the evolution of the service. In 1969 the CAB officially designated these small air carriers as commuter airlines. They were, and are subject to passenger limits and freight/weight restrictions. Nicholls continues by defining how air carriers are labeled and categorized post 1978; in the age of de-regulation.

The Political Economy of Climate Adaptation and Environmental Health: The Case of Ethiopia

The environment affects our health, livelihoods, and the social and political institutions within which we interact. Indeed, nearly a quarter of the global disease burden is attributed to environmental factors, and many of these factors are exacerbated by global climate change. Thus, the central research question of this dissertation is: How do people cope with and adapt to uncertainty, complexity, and change of environmental and health conditions? Specifically, I ask how institutional factors, risk aversion, and behaviors affect environmental health outcomes. I further assess the role of social capital in climate adaptation, and specifically compare individual and collective adaptation. I then analyze how policy develops accounting for both adaptation to the effects of climate and mitigation of climate-changing emissions. In order to empirically test the relationships between these variables at multiple levels, I combine multiple methods, including semi-structured interviews, surveys, and field experiments, along with health and water quality data. This dissertation uses the case of Ethiopia, Africa’s second-most populous nation, which has a large rural population and is considered very vulnerable to climate change. My fieldwork included interviews and institutional data collection at the national level, and a three-year study (2012-2014) of approximately 400 households in 20 villages in the Ethiopian Rift Valley. I evaluate the theoretical relationships between households, communities, and government in the process of adaptation to environmental stresses. Through my analyses, I demonstrate that water source choice varies by individual risk aversion and institutional context, which ultimately has implications for environmental health outcomes. I show that qualitative measures of trust predict cooperation in adaptation, consistent with social capital theory, but that measures of trust are negatively related with private adaptation by the individual. Finally, I describe how Ethiopia had some unique characteristics, significantly reinforced by international actors, that led to the development of an extensive climate policy, and yet with some challenges remaining for implementation. These results suggest a potential for adaptation through the interactions among individuals, communities, and government in the search for transformative processes when confronting environmental threats and climate change.

En Route Speed Reduction Concept for Absorbing Air Traffic Flow Management Delays

This paper proposes an en route speed reduction to complement current ground delay practices in air traffic flow management. Given a nominal cruise speed, there exists a bounded range of speeds that allows aircraft to fly slower with the same or lower fuel consumption than the nominal flight. Therefore, flight times are increased and delay can be partially performed in the air, at no extra fuel cost for the operator. This concept has been analyzed in an initial feasibility study, computing the maximum amount of delay that can be performed in the air in some representative flights. The impact on fuel consumption has been analyzed, and two scenarios are proposed: the flight fuel remains the same as in the nominal flight, and some extra fuel allowance is permitted in order to face uncertainties. Results show significant values of airborne delay that may be useful in many situations, with the exception of short hauls where airborne delay may be too short. If cruise altitude is changed, the amount of airborne delay increases, since changes in cruise speed modify the optimal flight altitudes. From the analyzed flights, a linear dependency is found relating the airborne delay with the amount of extra fuel allowance.

Indoor air quality in schools and its relationship with children's respiratory symptoms

A cross-sectional survey was conducted to characterize the indoor air quality (IAQ) in schools and its relationship with children's respiratory symptoms. Concentrations of volatile organic compounds (VOC), aldehydes, PM2.5, PM10, carbon dioxide, bacteria and fungi were assessed in 73 classrooms from 20 public primary schools located in Porto, Portugal. Children who attended the selected classrooms (n = 1134) were evaluated by a standardised health questionnaire completed by the legal guardians; spirometry and exhaled nitric oxide tests. The results indicated that no classrooms presented individual VOC pollutant concentrations higher than the WHO IAQ guidelines or by INDEX recommendations; while PM2.5, PM10 and bacteria levels exceeded the WHO air quality guidelines or national limit values. High levels of total VOC, acetaldehyde, PM2.5 and PM10 were associated with higher odds of wheezing in children. Thus, indoor air pollutants, some even at low exposure levels, were related with the development of respiratory symptoms. The results pointed out that it is crucial to take into account the unique characteristics of the public primary schools, to develop appropriate control strategies in order to reduce the exposure to indoor air pollutants and, therefore, to minimize the adverse health effects.

Physical aspects

As teachers, we must know about the physical developmental processes our students are experiencing. These are reflected in behaviour, emotions and relationships. And for adolescents, who are trying hard to figure out how the world operates, the physical changes they experience have a potent impact on their world view. While the sequencing of much of our physical development is pretty well according to a grand template and rolls out in much the same way from one person to the next, not everything occurs in a set way (Richter, 2006). Some aspects of our physical development cause other things to occur and are tied together. For example, hormonal changes during puberty are tied to the development of secondary sexual characteristics. However, there is individual variation at multiple levels, and we will discuss these. To complicate things, adolescents’ feelings and ideas about themselves and the ways in which they interact with the world as they grow and change are coloured by our societies’ multifaceted sets of ideals, standards and expectations for physical development. Many other things also impact on our conceptions of self and these will be discussed when we turn our attention to the development of identity through adolescence. In this chapter we will present some basic information about the types of physical changes to expect during adolescence, and consider some challenges that confront adolescents during this time of development.

MoBlogs, Sharing Situations, and Lived Life

This chapter considers shared encounters through blogging in the light of John Urry’s new mobilities paradigm. We review relevant literature on mobile blogging (moblogging) – blogging, pervasive image capture and sharing, moblogging and video blogging – and describe common issues with these digital content sharing practices. We then document some features of how technology affords “reflexive encounters” through the description of a blogging study involving smokers trying to quit, describing important connections between mobilities – physical, object, and communicative mobility. Finally, we present some challenges for new blogging technologies, their relevance to social encounters, and possible future directions through considering the mobile self; the new digital life document; and digital content sharing practices.

Multicultural education, global studies and studies of Asia

Like other nations, Australia has experienced significant change in the past few decades as its society has become increasingly diverse. The new cultures and traditions that result from ethnic and religious diversity have both enriched Australian society and presented it with some challenges. Other challenges have resulted from increased globalisation. For example, the economic fallout from the recent global financial crisis indicates that global issues can impact across a range of levels, from multinational corporations and nation-states to local sites and individual livelihoods. Some suggest that Australia fared better than other nations during this economic crisis because of its export trade with China. Although this is disputed by economists, it highlights another facet of change that is impacting on Australian society and this relates to Australia’s growing engagement with the nations of Asia. There is increasing awareness in education systems that if young people are to achieve their potential as future citizens they need to be able to negotiate the cultural, social, political and economic ties that connect them to the global and regional community through work, leisure and citizenship. Multicultural education, global studies and studies of Asia play a particular part in helping young people to: • appreciate cultural diversity within and beyond their own nation • imagine with some accuracy how others view their world • participate in shaping a better future. This chapter explores the origins, distinctions and common features of each approach.

Melt electrospinning

Melt electrospinning is relatively under-investigated compared to solution electrospinning but provides opportunities in numerous areas, in which solvent accumulation or toxicity are a concern. These applications are diverse, and provide a broad set of challenges to researchers involved in electrospinning. In this context, melt electrospinning provides an alternative approach that bypasses some challenges to solution electronspinning, while bringing new issues to the forefront, such as the thermal stability of polymers. This Focus Review describes the literature on melt electrospinning, as well as highlighting areas where both melt and solution are combined, and potentially merge together in the future.

Fitting airport privatisation to purpose : aligning governance, time and management focus

Where airports were once the sole responsibility of their governments, liberalisation of economies has seen administrative interests in airport spaces divested increasingly towards market led authority. Extant literature suggests that actions in decision spaces can be described under broad idealised forms of governance. However in looking at a sample of 18 different airports it is apparent that these classic models are insufficient to appreciate the contextual complexity of each case. Issues of institutional arrangements, privatisation, and management focus are reviewed against existing governance modes to produce a model for informing privatisation decisions, based on the contextual needs of the individual airport and region. Expanding governance modes to include emergent airport arrangements both contribute to the existing literature, and provides a framework to assist policy makers and those charged with the operation of airports to design effective governance models. In progressing this framework, contributions are made to government decision makers for the development of new, or review of existing strategies for privatisation, while the private sector can identify the intent and expectations of privatisation initiatives to make better informed decisions.

Check-in processing : simulation of passengers with advanced traits

In order to tackle the growth of air travelers in airports worldwide, it is important to simulate and understand passenger flows to predict future capacity constraints and levels of service. We discuss the ability of agent-based models to understand complicated pedestrian movement in built environments. In this paper we propose advanced passenger traits to enable more detailed modelling of behaviors in terminal buildings, particularly in the departure hall around the check-in facilities. To demonstrate the concepts, we perform a series of passenger agent simulations in a virtual airport terminal. In doing so, we generate a spatial distribution of passengers within the departure hall to ancillary facilities such as cafes, information kiosks and phone booths as well as common check-in facilities, and observe the effects this has on passenger check-in and departure hall dwell times, and facility utilization.

A study on the use of acoustic emission technique as a structural health monitoring tool

As civil infrastructures such as bridges age, there is a concern for safety and a need for cost-effective and reliable monitoring tool. Different diagnostic techniques are available nowadays for structural health monitoring (SHM) of bridges. Acoustic emission is one such technique with potential of predicting failure. The phenomenon of rapid release of energy within a material by crack initiation or growth in form of stress waves is known as acoustic emission (AE). AEtechnique involves recording the stress waves bymeans of sensors and subsequent analysis of the recorded signals,which then convey information about the nature of the source. AE can be used as a local SHM technique to monitor specific regions with visible presence of cracks or crack prone areas such as welded regions and joints with bolted connection or as a global technique to monitor the whole structure. Strength of AE technique lies in its ability to detect active crack activity, thus helping in prioritising maintenance work by helping focus on active cracks rather than dormant cracks. In spite of being a promising tool, some challenges do still exist behind the successful application of AE technique. One is the generation of large amount of data during the testing; hence an effective data analysis and management is necessary, especially for long term monitoring uses. Complications also arise as a number of spurious sources can giveAEsignals, therefore, different source discrimination strategies are necessary to identify genuine signals from spurious ones. Another major challenge is the quantification of damage level by appropriate analysis of data. Intensity analysis using severity and historic indices as well as b-value analysis are some important methods and will be discussed and applied for analysis of laboratory experimental data in this paper.
