The Distributed Software Development (DSD) is a development strategy that meets the globalization needs concerned with the increase productivity and cost reduction. However, the temporal distance, geographical dispersion and the socio-cultural differences, increased some challenges and, especially, added new requirements related with the communication, coordination and control of projects. Among these new demands there is the necessity of a software process that provides adequate support to the distributed software development. This paper presents an integrated approach of software development and test that considers distributed teams peculiarities. The approach purpose is to offer support to DSD, providing a better project visibility, improving the communication between the development and test teams, minimizing the ambiguity and difficulty to understand the artifacts and activities. This integrated approach was conceived based on four pillars: (i) to identify the DSD peculiarities concerned with development and test processes, (ii) to define the necessary elements to compose the integrated approach of development and test to support the distributed teams, (iii) to describe and specify the workflows, artifacts, and roles of the approach...

AIMS--A survey was undertaken to assess the effectiveness of an integrated approach to the provision of low visual aids (LVAs) in south Devon over a 2 year follow up period. This integrated approach includes the assessment of patient needs by low vision therapists, followed by the provision of suitable LVAs, with particular emphasis on training in their use. METHODS--A total of 125 patients were selected at random from the 445 patients seen in the low vision clinic at Torbay Hospital in the year 1991. These patients were sent questionnaires relating to the service over a 2 year period. Questionnaires from 111 patients were analysed at 1 year and 75 questionnaires together with 46 clinical reassessments, after 2 years. RESULTS--Using a similar questionnaire to one used in a previous study in the UK from a unit where LVA training was not provided, not only was a higher rate of satisfaction found with the services provided, but also the LVAs dispensed were used more frequently. The majority of the LVAs provided were of the simple, inexpensive variety and wastage was very low. CONCLUSIONS--It was concluded that this integrated approach to low vision rehabilitation with emphasis on training in the use of less complex LVAs exceeds the performance of other types of service that rely on the dispensing of more complex LVAs.

Multiple-species parasitic infections are pervasive in the developing world, yet resources for their control are scarce. We present an integrated approach for risk profiling and spatial prediction of coinfection with Schistosoma mansoni and hookworm for western Côte d’Ivoire. Our approach combines demographic, environmental, and socioeconomic data; incorporates them into a geographic information system; and employs spatial statistics. Demographic and socioeconomic data were obtained from education registries and from a questionnaire administered to schoolchildren. Environmental data were derived from remotely sensed satellite images and digitized ground maps. Parasitologic data, obtained from fecal examination by using two different diagnostic approaches, served as the outcome measure. Bayesian variogram models were used to assess risk factors and spatial variation of S. mansoni–hookworm coinfection in relation to demographic, environmental, and socioeconomic variables. Coinfections were found in 680 of 3,578 schoolchildren (19.0%) with complete data records. The prevalence of monoinfections with either hookworm or S. mansoni was 24.3% and 24.1%, respectively. Multinomial Bayesian spatial models showed that age, sex, socioeconomic status...

A safe, effective, and acceptable microbicide is needed in order to decisively impact the global AIDS pandemic. As such, microbicide acceptability research is of paramount importance. In order to best utilize limited financial resources and save precious development time, acceptability studies should be fully integrated into preclinical and clinical trial contexts where candidate products are being developed and tested. An integrated approach for examining theoretically valid and relevant variables is needed so that data across studies and products can more effectively advance the field. We propose an approach for measuring factors related to microbicide acceptability in each phase of product development, and dependent on what product-specific knowledge is already established in the field. We discuss the roles that behavioral and social science methodologies should play in all phases of microbicide development, as well as the challenges faced when conducting acceptability research in the context of preclinical and clinical trial settings.

A multidisciplinary team of researchers at the Center for the Promotion of Health in the New England Workplace (CPH-NEW) developed an evidence-based approach to address three recognized challenges to workplace programs designed to improve employee health: establishing employee ownership, integrating with work organization, and sustainability. The two main innovations being introduced in combination were (1) integrating traditional workplace health protection (e.g., ergonomics, industrial hygiene) with health promotion (e.g., assisting workers in improving health behaviors) and (2) introducing a bottom-up participatory model for engaging employees in innovative iterative design efforts to enhance both components of this integrated program. In the program, which was modeled after participatory ergonomics programs, teams of workers engage in the iterative design of workplace interventions to address their prioritized health concerns with the support of a multilevel steering committee. The integrated approach being tested can complement existing worksite safety and health initiatives and promote organizational learning, with expected synergistic effects.

The importance of the neuropsychological aspect in patients affected by tension headache is highlighted by different data in the literature as well as the results of a multicentric Italian study on comorbidity linked to consistent pathologies, from psychiatric to psychopathologies, in cephalalgic subjects. The need for an integrated approach to the treatment of migraine comes from the assumption, which has recently been confirmed by research, that cephalalgic patients, depending on their emotional condition, have difficulty in dealing with anxiety or other forms of stress in their everyday life. An integrated intervention is extremely useful both in the diagnostic and in the therapeutical approach. For 6 months, 64 patients with migraine without aura were subjected to an integrated therapeutical approach (the median age was 39 years). A number of exclusion criteria were used. The first group comprised 34 patients with migraine without aura having fewer than 4 attacks per month, while the second group comprised 30 patients with migraine without aura having more than four attacks per month. The psychological intervention involved clinical colloquia, such as Jacobson’s muscle relaxation technique as well as tests and clinical questionnaires (follow-up and discussion). The follow-up assessed parameters relative to the attacks: frequency...

New drug discovery is facing serious challenges due to reduction in number of new drug approvals coupled with exorbitant rising cost. Advent of combinatorial chemistry provided new hope of higher success rates of new chemical entities (NCEs); however, even this scientific development has failed to improve the success rate in new drug discovery. This scenario has prompted us to come out with a novel approach of integrated drug discovery, where Ayurvedic wisdom can synergize with drug discovery from plant sources. Initial steps in new drug discovery involve identification of NCEs, which can be either sourced through chemical synthesis or can be isolated from natural products through biological activity guided fractionation. The sources of many of the new drugs and active ingredients of medicines are derived from natural products. The starting point for plant-based new drug discovery should be identification of the right candidate plants by applying Ayurvedic wisdom, traditional documented use, tribal non-documented use, and exhaustive literature search. Frequency analysis of the ingredients of the ancient documented formulations and analysis of their Ayurvedic attributes may provide an in-depth idea of the predominance of particular Ayurvedic characteristics based on which appropriate candidate plants may be selected for bioactivity-based fractionation. The integration of Ayurvedic wisdom with drug discovery also brings the need for a paradigm shift in the extraction process from sequential to parallel extraction. Bioassay-guided fractionation of the identified plant may lead to standardized extract or isolated bioactive druggable compound as the new drug. This integrated approach would lead to saving of cost and time...

In 1986, Vietnam opened up the country’s economy by launching the Doi Moi (renovation) policy, which made the process of economic liberalisation possible. Accordingly, Ho Chi Minh City, the country’s biggest city, has undergone rapid growth of population, urbanisation and industrialisation. While achieving remarkable economic growth, the city faces considerable urban environmental challenges. The rapid growth of urbanisation and industry has placed increasing pressure on available freshwater resources, through excessive water use and increasing volumes of untreated wastewater. Firstly, the urban water sector has had to meet growing demand for water use for domestic purposes during the dry season. Secondly, groundwater levels have experienced a substantial drawdown in outlying urban districts as a result of over-abstraction. Thirdly, rapidly expanding industrial activities are causing severe demand on water resources. The city’s major supply sources have developed an alarming level of pollutants discharged by industry. The aim of this thesis is to formulate an integrated approach to the sustainable management of water resources in Ho Chi Minh City. In order to achieve this, the research was designed to examine institutional frameworks and arrangements and to explore the perception of water value by water users and stakeholders. The underlying reasons for ineffective management are anchored in fragmented management practices which result from inadequate institutional frameworks and arrangements...

Integrated coastal management (ICM) has had limited success in the Asia-Pacific region where, according to the literature, only three countries have inter-agency or inter-ministerial coordinating mechanisms, including Indonesia as the only developing country. However, there is a lack of research into the practice and efficiency of these coordinating mechanisms in Indonesia and the extent to which ICM can operate in practice, particularly in areas with complex administration such as Jakarta Bay. This research aims to investigate the applicability of an ICM approach within the existing Indonesian governance systems focusing on Jakarta Bay. The bay is adjacent to the Jakarta metropolitan area of 6,406.33 km², which is inhabited by approximately 28 million people, has some of the highest economic development in in the country, is experiencing population growth, and economic development pressures related to pollution, erosion, subsidence, flooding, habitat degradation and loss of ecosystem. These diverse problems are subject to the complexities of management between different sectors and jurisdictional boundaries. It is in this context that this research investigates an integrated approach for managing coastal areas of Jakarta Bay. The research was carried out in two steps. First...

Community pharmacy is part of the health care system which is currently under economic pressure and facing changes in demands from consumers and government. In response, the pharmacy profession is becoming more patient orientated and implementing cognitive pharmaceutical services (CPS). CPS in various countries has similar objectives with different emphasis, definitions, labels and using different tools. However, they can be classified using a broad hierarchical model based on clinical decision making and the extent of change required (Box 1). The challenges faced by the profession are related the development of a new patient orientated model of pharmacy which affects health care policy, education and research, the evolution of the market, the individual and organisational approaches to change and the implementation of CPS. These issues and previous research conducted in pharmacy practice have been synthesised to provide a platform for change that can guide a holistic and integrated approach to CPS implementation. Implementation can be conceptually framed in six levels: clinical, service provision, community pharmacy, professional organisation, government and stakeholder (Figure 1). Past experience with service implementation has seen the application of programs that include one or two of these levels in practice rather than a holistic approach. A concentric model was developed to illustrate the implementation of CPS and the holistic and integrated approach required to support change. A program (conSIGUE) being conducted in Spain has attempted to integrate all six levels to support the implementation and evaluation of a medication management service (Seguimiento Farmacoterap??utico); La Farmacia Comunitaria forma parte del sistema de salud. Este sistema actualmente se encuentra sometido a presiones econ??micas y debe afrontar cambios en la demanda tanto de los consumidores como de los gobiernos. La respuesta de la profesi??n farmac??utica est?? dirigida a orientar su pr??ctica hacia el paciente y a implantar servicios cognitivos farmac??uticos (CPS). En distintos pa??ses estos servicios tiene objetivos similares aunque presentan diferencias en el ??nfasis de los servicios...

While India has, over the last few decades, made considerable progress in ensuring child survival and basic education, much remains to be done. When the major indicators for the Indian child's development -- maternal mortality, birth weight, immunization, nutrition level and basic education - are compared with those of other developing countries, it is clear that the Indian child urgently needs better interventions. In the context of such a situation, the vision for the future has to be an India where all children have all the chances they need for optimal development. The emerging question is, despite significant investments and a conducive policy framework, why is the status of the Indian child still far from satisfactory? And, what then is the way forward to realize this vision? It was in this context that a multi-sectoral workshop entitled "Reaching Out to the Child" was organized collaboratively by the Education and Health, Nutrition and Population teams of the World Bank on February 21 and 22, 2000 with the participation of Indian professionals from health...

Any highly available data warehouse will use some form of data replication to ensure that it can continue to service queries despite machine failures. In this thesis, I demonstrate that it is possible to leverage the data replication available in these environments to build a simple yet efficient crash recovery mechanism that revives a crashed site by querying remote replicas for missing updates. My new integrated approach to recovery and high availability, called HARBOR (High Availability and Replication-Based Online Recovery), targets updatable data warehouses and offers an attractive alternative to the widely used log-based crash recovery algorithms found in existing database systems. Aside from its simplicity over log-based approaches, HARBOR also avoids the runtime overhead of maintaining an on-disk log, accomplishes recovery without quiescing the system, allows replicated data to be stored in non-identical formats, and supports the parallel recovery of multiple sites and database objects. To evaluate HARBOR's feasibility, I compare HARBOR's runtime overhead and recovery performance with those of two-phase commit and ARIES, the gold standard for log-based recovery, on a four-node distributed database system that I have implemented.; (cont.) My experiments show that HARBOR incurs lower runtime overhead because it does not require log writes to be forced to disk during transaction commit. Furthermore...

Experts stress the need to bring the childhood obesity epidemic under control by means of an integrated approach. The implementation of such an approach requires the development of integrated enabling policies on public health by local governments. A prerequisite for developing such integrated public health policies is intersectoral collaboration. Since the development of integrated policies is still in its early stages, this study aimed to answer the following research question: “What interventions can promote intersectoral collaboration and the development of integrated health policies for the prevention of childhood obesity?” Data were collected through a literature search and observations of and interviews with stakeholders. Based on a theoretical framework, we categorized potential interventions that could optimize an integrated approach regarding children's physical activity and diet. The intervention categories included education, persuasion, incentivization, coercion, training, restriction, environmental restructuring, modeling, and enablement.

To assess whether a given time series can be modeled by a stochastic process possessing long range correlation one usually applies one of two types of analysis methods: the spectral method and the random walk analysis. The first objective of this work is to show that each one of these methods used alone can be susceptible to producing false results. We thus advocate an integrated approach which requires the use of both methods in a consistent fashion. We provide the theoretical foundation of this approach and illustrate the main ideas using examples. The second objective relates to the observation of long range anticorrelation (Hurst exponent H < 1/2) in real world time series data. The very peculiar nature of such processes is emphasized in light of the stringent condition under which such processes can occur. Using examples we discuss the possible factors that could contribute to the false claim of long range anticorrelations and demonstrate the particular importance of the integrated approach in this case.; Comment: 15 pages, 33 figures

This is the author accepted manuscript. The final version is available from Taylor & Francis via http://dx.doi.org/10.1080/13664530.2015.1079550; This paper refers to the Dynamic Integrated Approach towards teacher professional development which attempts to merge research findings on teacher effectiveness and teacher professional development. The theoretical framework and the major features of the DIA are presented. It is argued that the DIA can be effectively implemented through five steps: Establishing clarity and consensus about aims and objectives, identifying needs and priorities for improvement through empirical investigation, provision of improvement guidelines, reflection opportunities and coaching on effective teaching by the advisory and research team, establishing a formative evaluation mechanism and finally establishing a summative evaluation system. Results of empirical studies providing support to the basic elements and the overall effectiveness of the DIA are also presented. Implications of the findings are discussed and suggestions for further research, particularly in exploring the conditions under which the DIA could have a long lasting effect on teacher effectiveness, are finally drawn.

Hough-Goldstein, Judith; Disturbed areas frequently experience invasion by introduced plant species and subsequently a drop in species richness and ecosystem services. Research on the best means of removing these species abounds, but typically does not include techniques to restore the invaded habitat. Without such restoration the introduced species often re-occur, or an alternate introduced invasive plant fills the opened niche. This study investigated an integrated approach to controlling the introduced annual Persicaria perfoliata [L.] H. Gross (mile-a-minute weed) using the Asian biocontrol weevil Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) and establishment of native plants from seed. The native seed mix used was comprised of five widely adapted plant species, three grasses and two forbs. A fully factorial design integrated weevils and seeding, using a systemic insecticide as a control. In a field setting, areas of well-established mile-a-minute weed were sown with natives in early spring when the weed germinated. A weevil population had been established at the site one year prior to sowing and was augmented both years of the experiment. By year two there was significantly lower P. perfoliata mean biomass and percent cover in plots integrating weevils and native seeds than seed-only or control plots. Further...

To meet the challenges of sustainability and catchment management requires an approach that assesses resource usage options and environmental impacts integratively. Assessment must be able to integrate several dimensions: the consideration of multiple issues and stakeholders, the key disciplines within and between the human and natural sciences, multiple scales of system behaviour, cascading effects both spatially and temporally, models of the different system components, and multiple databases. Integrated assessment (IA) is an emerging discipline and process that attempts to address the demands of decision makers for management that has ecological, social and economic values and considerations. This paper summarises the features of IA and argues the role for models and information systems as a prime activity. Given the complex nature of IA problems, the broad objectives of IA modelling should be to understand the directions and magnitudes of change in relation to management interventions so as to be able to differentiate between associated outcome sets. Central to this broad objective is the need for improved techniques of uncertainty and sensitivity analysis that can provide a measure of confidence in the ability to differentiate between different decisions. Three examples of problems treated with an IA approach are presented. The variations in the way that the different dimensions are integrated in the modelling are discussed to highlight the sorts of choices that can be made in model construction. The conclusions stress the importance of IA as a process...

Integrated assessment is a discipline that takes a holistic, problem-oriented approach to scientific assessment. It is increasingly being applied to consider a range of environmental issues, including water resource management problems. This paper considers lessons for integrated assessment arising from a project focused on water allocation options in the Namoi River catchment, Australia. It is seen how the problem focus of this work prescribes the requirements placed on the structure, components and conceptualisation of the integrated assessment model. A brief description of the model illustrates the ways in which these requirements are addressed. Lessons for integrated assessment arising from this work are then described. These relate to the importance of identifying the modeling problem and objectives, balancing disciplinary perspectives, selecting appropriate spatial and temporal scales, and development of trust with stakeholder groups.

The development of short- and medium-term mine production schedules in isolation from each other has meant that only a local optimum can be achieved when each scheduling phase is carried out. The globally optimal solution, however, can be achieved when integrating scheduling phases and accounting for the interaction between short-term and medium-term activities simultaneously. This paper addresses the task of integrating short- and medium-term production plans by combining the short-term objective of minimizing deviation from targeted mill feed grade with the medium-term objective of maximizing net present value (NPV) into a single mathematical optimization model. A conceptual sublevel stoping operation comprising 30 stopes is used for trialling segregated and integrated scheduling approaches. Segregated medium- and short-term scheduling using separate models achieved an NPV of $42 654 456. The final scheduling approach involved integrating the two scheduling horizons using the newly-developed globally optimal integrated production scheduling model to achieve an NPV of $42 823 657 with smoother mill feed grade. The larger the stope data set, the larger the difference between the two scheduling approaches is likely to be. At the very least...
