A methodology for implementing a decision support system:a small company case study

The importance of non-technical factors in the design and implementation of information systems has been increasingly recognised by both researchers and practitioners, and recent literature highlights the need for new tools and techniques with an organisational, rather than technical, focus. The gap between what is technically possible and what is generally practised, is particularly wide in the sales and marketing field. This research describes the design and implementation of a decision support system (DSS) for marketing planning and control in a small, but complex company and examines the nature of the difficulties encountered. An intermediary with functional, rather than technical, expertise is used as a strategy for overcoming these by taking control of the whole of the systems design and implementation cycle. Given the practical nature of the research, an action research approach is adopted with the researcher undertaking this role. This approach provides a detailed case study of what actually happens during the DSS development cycle, allowing the influence of organisational factors to be captured. The findings of the research show how the main focus of the intermediary's role needs to be adapted over the systems development cycle; from coordination and liaison in the pre-design and design stages, to systems champion during the first part of the implementation stage, and finally to catalyst to ensure that the DSS is integrated into the decision-making process. Two practical marketing exercises are undertaken which illustrate the nature of the gap between the provision of information and its use. The lack of a formal approach to planning and control is shown to have a significant effect on the way the DSS is used and the role of the intermediary is extended successfully to accommodate this factor. This leads to the conclusion that for the DSS to play a fully effective role, small firms may need to introduce more structure into their marketing planning, and that the role of the intermediary, or Information Coordinator, should include the responsibility for introducing new techniques and ideas to aid with this.

An examination of organisational issues in third sector organisations which undertake nonviolent direct action

This thesis is an examination of organisational issues faced by Third Sector organisations which undertake nonviolent direct action. A case study methodology is employed and data gathered from four organisations: Earth First!; genetiX Snowball; Greenpeace; and Trident Ploughshares. The argument commences with a review of the literature which shows that little is known of the organising of nonviolent direct action. Operational definitions of 'organisation' and 'nonviolent direct action' are drawn from the literature. 'Organisation' is conceptualised using new institutionalism. 'Nonviolent direct action' is conceptualised using new social movement theory. These concepts inform the case study methodology in the choice of case, the organisations selected and the data gathering tools. Most data were gathered by semi-structured interview and participant observation. The research findings result from theory-building arising from thick descriptions of the case in the four organisations. The findings suggest that nonviolent direct action is qualitatively different from terrorism or violence. Although there is much diversity in philosophies of nonviolence, the practice of nonviolent direct action has much in common across the four organisations. The argument is that nonviolent direct action is an institution. The findings also suggest that new institutionalism is a fruitful approach to studies of these organisations. Along with nonviolent direct action, three other institutions are identified: 'rules'; consensus decision-making; and 'affinity groups'. An unanticipated finding is how the four organisations are instances of innovation. Tentative theory is developed which brings together the seemingly incompatible concepts of institutions and innovation. The theory suggests preconditions and then stages in the development of new organisational forms in new social movements: innovation. The three pre-conditions are: the existence of an institutional field; an 'institution-broker' with access to different domains; and a shared 'problem' to resolve. The three stages are: unlocking existing knowledge and practice; bridging different domains of practice or different fields to add, develop or translocate those practices; and establishing those practices within their new combinations or novel locations. Participants are able to move into and between these new organisational forms because they consist of familiar and habitual institutional behaviour.

What to expect after the honeymoon:testing a life cycle theory of franchise relationships

This research examines the evolution of interorganizational relationships in a franchising context. Using U-curve theory, we develop three hypotheses and contrast them with traditional lifecycle theory. Three groups of constructs are affected by lifecycle: cooperation variables, dependence variables, and relationship variables. Four distinct stages emerge, with highest levels of variables in the honeymoon stage, lower levels in routine and crossroad stages, and increasing levels in the stabilization stage. Franchisors should strive for “stability on high levels” before operational realities influence the franchisees. Franchisees’ intermediate lifecycle phases are most critical for the system, since opportunistic behavior and switching are most likely.

Interpreting adverse signals in diabetes drug development programs

Detection and interpretation of adverse signals during preclinical and clinical stages of drug development inform the benefit-risk assessment that determines suitability for use in real-world situations. This review considers some recent signals associated with diabetes therapies, illustrating the difficulties in ascribing causality and evaluating absolute risk, predictability, prevention, and containment. Individual clinical trials are necessarily restricted for patient selection, number, and duration; they can introduce allocation and ascertainment bias and they often rely on biomarkers to estimate long-term clinical outcomes. In diabetes, the risk perspective is inevitably confounded by emergent comorbid conditions and potential interactions that limit therapeutic choice, hence the need for new therapies and better use of existing therapies to address the consequences of protracted glucotoxicity. However, for some therapies, the adverse effects may take several years to emerge, and it is evident that faint initial signals under trial conditions cannot be expected to foretell all eventualities. Thus, as information and experience accumulate with time, it should be accepted that benefit-risk deliberations will be refined, and adjustments to prescribing indications may become appropriate. © 2013 by the American Diabetes Association.

Anisotropic characterization of crack growth in the tertiary flow of asphalt mixtures in compression

Asphalt mixtures exhibit primary, secondary, and tertiary stages in sequence during a rutting deterioration. Many field asphalt pavements are still in service even when the asphalt layer is in the tertiary stage, and rehabilitation is not performed until a significant amount of rutting accompanied by numerous macrocracks is observed. The objective of this study was to provide a mechanistic method to model the anisotropic cracking of the asphalt mixtures in compression during the tertiary stage of rutting. Laboratory tests including nondestructive and destructive tests were performed to obtain the viscoelastic and viscofracture properties of the asphalt mixtures. Each of the measured axial and radial total strains in the destructive tests were decomposed into elastic, plastic, viscoelastic, viscoplastic, and viscofracture strains using the pseudostrain method in an extended elastic-viscoelastic correspondence principle. The viscofracture strains are caused by the crack growth, which is primarily signaled by the increase of phase angle in the tertiary flow. The viscofracture properties are characterized using the anisotropic damage densities (i.e., the ratio of the lost area caused by cracks to the original total area in orthogonal directions). Using the decomposed axial and radial viscofracture strains, the axial and radial damage densities were determined by using a dissipated pseudostrain energy balance principle and a geometric analysis of the cracks, respectively. Anisotropic pseudo J-integral Paris' laws in terms of damage densities were used to characterize the evolution of the cracks in compression. The material constants in the Paris' law are determined and found to be highly correlated. These tests, analysis, and modeling were performed on different asphalt mixtures with two binders, two air void contents, and three aging periods. Consistent results were obtained; for instance, a stiffer asphalt mixture is demonstrated to have a higher modulus, a lower phase angle, a greater flow number, and a larger n1 value (exponent of Paris' law). The calculation of the orientation of cracks demonstrates that the asphalt mixture with 4% air voids has a brittle fracture and a splitting crack mode, whereas the asphalt mixture with 7% air voids tends to have a ductile fracture and a diagonal sliding crack mode. Cracks of the asphalt mixtures in compression are inclined to propagate along the direction of the external compressive load. © 2014 American Society of Civil Engineers.

Mechanistic modeling of fracture in asphalt mixtures under compressive loading

When an asphalt mixture is subjected to a destructive compressive load, it experiences a sequence of three deformation stages, as follows: the (1) primary, (2) secondary, and (3) tertiary stages. Most literature research focuses on plastic deformation in the primary and secondary stages, such as prediction of the flow number, which is in fact the initiation of the tertiary stage. However, little research effort has been reported on the mechanistic modeling of the damage that occurs in the tertiary stage. The main objective of this paper is to provide a mechanistic characterizing method for the damage modeling of asphalt mixtures in the tertiary stage. The preliminary study conducted by the writers illustrates that deformation during the tertiary flow of the asphalt mixtures is principally caused by the formation and propagation of cracks, which was signaled by the increase of the phase angle in the tertiary phase. The strain caused by the growth of cracks is the viscofracture strain, which can be obtained by conducting the strain decomposition of the measured total strain in the destructive compressive test. The viscofracture strain is employed in the research reported in this paper to mechanistically characterize the time-dependent fracture (viscofracture) of asphalt mixtures in compression. By using the dissipated pseudostrain energy-balance principle, the damage density and true stress are determined and both are demonstrated to increase with load cycles in the tertiary stage. The increased true stress yields extra viscoplastic strain, which is the reason why the permanent deformation is accelerated by the occurrence of cracks. To characterize the evolution of the viscofracture in the asphalt mixtures in compression, a pseudo J-integral Paris' law in terms of damage density is proposed and the material constants in the Paris' law are determined, which can be employed to predict the fracture of asphalt mixtures in compression. © 2013 American Society of Civil Engineers.

The challenges of developing an online tool to measure the quality of the passenger experience in a PanEuropean context

METPEX is a 3 year, FP7 project which aims to develop a PanEuropean tool to measure the quality of the passenger's experience of multimodal transport. Initial work has led to the development of a comprehensive set of variables relating to different passenger groups, forms of transport and journey stages. This paper addresses the main challenges in transforming the variables into usable, accessible computer based tools allowing for the real time collection of information, across multiple journey stages in different EU countries. Non-computer based measurement instruments will be used to gather information from those who may not have or be familiar with mobile technology. Smartphone-based measurement instruments will also be used, hosted in two applications. The mobile applications need to be easy to use, configurable and adaptable according to the context of use. They should also be inherently interesting and rewarding for the participant, whilst allowing for the collection of high quality, valid and reliable data from all journey types and stages (from planning, through to entry into and egress from different transport modes, travel on public and personal vehicles and support of active forms of transport (e.g. cycling and walking). During all phases of the data collection and processing, the privacy of the participant is highly regarded and is ensured. © 2014 Springer International Publishing.

Implementing a knowledge management system within an NHS hospital:a case study exploring the roll-out of an Electronic Patient Record (EPR)

This research aims to contribute to understanding the implementation of knowledge management systems (KMS) in the field of health through a case study, leading to theory building and theory extension. We use the concept of the business process approach to knowledge management as a theoretical lens to analyse and explore how a large teaching hospital developed, executed and practically implemented a KMS. A qualitative study was conducted over a 2.5 year period with data collected from semi-structured interviews with eight members of the strategic management team, 12 clinical users and 20 patients in addition to non-participant observation of meetings and documents. The theoretical propositions strategy was used as the overarching approach for data analysis. Our case study provides evidence that true patient centred approaches to supporting care delivery with a KMS benefit from process thinking at both the planning and implementation stages, and an emphasis on the knowledge demands resulting from: the activities along the care pathways; where cross-overs in care occur; and knowledge sharing for the integration of care. The findings also suggest that despite the theoretical awareness of KMS implementation methodologies, the actual execution of such systems requires practice and learning. Flexible, fluid approaches through rehearsal are important and communications strategies should focus heavily on transparency incorporating both structured and unstructured communication methods.

A sensory-guided surgical micro-drill

This article describes a surgical robotic device that is able to discriminate tissue interfaces and other controlling parameters ahead of the drill tip. The advantage in such a surgery is that the tissues at the interfaces can be preserved. A smart tool detects ahead of the tool point and is able to control the interaction with respect to the flexing tissue, to avoid penetration or to control the extent of protrusion with respect to the position of the tissue. For surgical procedures, where precision is required, the tool offers significant benefit. To interpret the drilling conditions and the conditions leading up to breakthrough at a tissue interface, a sensing scheme is used that discriminates between the variety of conditions posed in the drilling environment. The result is a fully autonomous system, which is able to respond to the tissue type, behaviour, and deflection in real-time. The system is also robust in terms of disturbances encountered in the operating theatre. The device is pragmatic. It is intuitive to use, efficient to set up, and uses standard drill bits. The micro-drill, which has been used to prepare cochleostomies in the theatre, was used to remove the bone tissue leaving the endosteal membrane intact. This has enabled the preservation of sterility and the drilling debris to be removed prior to the insertion of the electrode. It is expected that this technique will promote the preservation of hearing and reduce the possibility of complications. The article describes the device (including simulated drill progress and hardware set-up) and the stages leading up to its use in the theatre. © 2010 Authors.

The effects of a professional development course on the teaching practices of P--12 classroom teachers

This follow-up study examined the long term effects of a staff development model on P–12 classroom teachers' instructional practices and dispositions regarding a curricular innovation. The sample, 44 private school practitioners who participated in the staff development program that used the model, was administered a survey at three checkpoints over a three year period to gather quantitative data regarding the participants' concerns about the curricular innovation. A comparison group of 19 practitioners also completed the survey. Qualitative data, gathered through interviews conducted with ten of the 44 participants, contributed to understanding the participants' perspectives on changes they perceived in their teaching practices as a result of the staff development. Elements of the model that were most instrumental in effecting those changes were identified. ^ The findings indicated that the participants demonstrated changes in the quality of their concerns, moving from self concerns and task concerns to impact concerns immediately following the training. The decrease in self concerns was sustained three years after the staff development, while task concerns increased and impact concerns returned to pre staff development levels. A significant difference in stages of concern between the participant and the comparison groups was noted at self and impact stages. ^ Findings revealed that participants changed their teaching practices and beliefs about instructional processes as a result of the staff development, becoming more collaborative and confident in implementing innovative approaches; they were perceived as leaders among their peers. Elements of the staff development model that participants identified as being influential in the change process included the opportunity for collaboration, authenticity of the training activities, and ongoing and comprehensive nature of the training. ^

Integrated surface-ground water modeling in wetlands with improved methods to simulate vegetative resistance to flow

In topographically flat wetlands, where shallow water table and conductive soil may develop as a result of wet and dry seasons, the connection between surface water and groundwater is not only present, but perhaps the key factor dominating the magnitude and direction of water flux. Due to their complex characteristics, modeling waterflow through wetlands using more realistic process formulations (integrated surface-ground water and vegetative resistance) is an actual necessity. This dissertation focused on developing an integrated surface – subsurface hydrologic simulation numerical model by programming and testing the coupling of the USGS MODFLOW-2005 Groundwater Flow Process (GWF) package (USGS, 2005) with the 2D surface water routing model: FLO-2D (O’Brien et al., 1993). The coupling included the necessary procedures to numerically integrate and verify both models as a single computational software system that will heretofore be referred to as WHIMFLO-2D (Wetlands Hydrology Integrated Model). An improved physical formulation of flow resistance through vegetation in shallow waters based on the concept of drag force was also implemented for the simulations of floodplains, while the use of the classical methods (e.g., Manning, Chezy, Darcy-Weisbach) to calculate flow resistance has been maintained for the canals and deeper waters. A preliminary demonstration exercise WHIMFLO-2D in an existing field site was developed for the Loxahatchee Impoundment Landscape Assessment (LILA), an 80 acre area, located at the Arthur R. Marshall Loxahatchee National Wild Life Refuge in Boynton Beach, Florida. After applying a number of simplifying assumptions, results have illustrated the ability of the model to simulate the hydrology of a wetland. In this illustrative case, a comparison between measured and simulated stages level showed an average error of 0.31% with a maximum error of 2.8%. Comparison of measured and simulated groundwater head levels showed an average error of 0.18% with a maximum of 2.9%. The coupling of FLO-2D model with MODFLOW-2005 model and the incorporation of the dynamic effect of flow resistance due to vegetation performed in the new modeling tool WHIMFLO-2D is an important contribution to the field of numerical modeling of hydrologic flow in wetlands.

A crise de legitimidade na democracia representativa e o desatendimento aos direitos fundamentais: um enfoque participativo-educacional

This study aims to bring reflection on the legitimacy crisis of the Brazilian representative democracy, which results in non-attendance of fundamental rights, regarding legal and social facts in light of the existing constitutional order and seeking solutions in more democratic procedures and in a more humane, critical, democratic and collaborative education. It has been an issue for some time the understanding that the authorities do not meet the basic needs of Brazilian citizens - the only way to make them autonomous and sufficiently able to conduct their lives in a competitive and globalized labor market. Such situation only worsened - as illustrated by the social movements in mid-2013 - when people took to the streets, showing a noticeable dissatisfaction with public services in general, and some other groups presenting specific complaints in those events. To find solutions or at least suggestions for the reflection of the problem found, a current approach to public authorities was necessary attempting to reveal how the constitutional order authorizes their operation and how - in fact - they act. In this endeavour, the legitimacy of power was discussed, involving the analysis of its origin, to whom it belongs and the legitimacy of deficit situations, concluding that it is only justified as it gets more democratic influence, with greater participation of people in its deliberations and decisions, with its plurality and complexity. Research carried out by official institutions was necessary to have evidence of the low level of social development of the country and the nonattendance of minimum basic rights, as well as exposure to various acts and omissions which show that all public authorities do not legitimately represent the people's interests. The competence of the Supreme Court to establish the broader scope of the remuneration policy in the public service received proper attention, presenting itself as an effective means to promote the reduction of the remuneration and structural inequality in public service and contributing to better care of fundamental rights. Also, considerations were made about the Decree 8243/2014, which established the National Policy for Social Participation (NPSP) and the National System of Social Participation (NSSP) and took other measures with the suggestion of its expansion into the legislative and judiciary powers as a way to legitimize the Brazilian democracy, considering its current stage. In conclusion, it is presented the idea expressed by the most influential and modern pedagogical trends for the creation of a participatory, solidary, non-hierarchical and critical culture since the childhood stage. This idea focuses on the resolution of questions addressed to the common good, which considers the complexity and the existing pluralism in society with a view to constant knowledge update. Knowledge update is in turn dynamic and requires such action, instilling - for the future generations - the idea that the creation of a more participatory and collaborative democracy is needed to reduce social inequality as a way to legitimize and promote social welfare, with the implementation of a policy devoted to meet the minimum fundamental rights to ensure dignity to the population.

Políticas públicas, desenvolvimento local e participação social nas instâncias de governança associadas ao turismo no Rio Grande do Norte

In contemporary dynamics, a change is observed in the institutional structure of the state, culminating in several policies for the tourist sector which promote a new management format. The from this view, the Tourism Regionalization Macro Program (TRP), considered a significant program to Ministry of Tourism, arose as an answer to this new reality, having as strategy a joint working of structuring and promotion turned at decentralization of actions, valuing the residents participation in the search of the permanent dialogue between peers and revaluation of places and territories, based in the regionalization process. Based on this bias, this study aims to examine the role of the Tourism State Council of Rio Grande do Norte, with regard to the tourism planning, trying to understand it and solve it as governance Instance, through the Tourism Regionalization Program interventions, given the participation context of its actors and agents. For purposes of this study is delimited as time frame the year 2007 at 2014, understanding that it was this time, there was greater council members accession, as well as different types of sectors representation of civil society, as a result of a tourism public policy based on principles of innovation and participation. In relation to the research problem, this study is conceptualized as a qualitative and the chosen method is the materialist dialectic. Still on the methodological options, utilize the Content Analysis. The results show that the institutionalization of governance instance as the Conetur does not contributes, ideally, in the planning and management process of participatory and integrated tourist activity, facing a fair direction of your space production. The research indicates that there are debates, discussions and guidelines (still in a timely and targeted form), but not reverberates practical effects, by act in a conjuncture that Is strategically designed for political and economic power game, setting the hegemonic actors performance, which uses this arena to instill personal desires and wishes, that are decided in absentia to the council.

The research aimed to construct and validate a data collection instrument of pregnant couple as part of primary care. It was considered hypothesis that level of agreement from 70% among participants to validate the expert panel. The document has been based on the Theory of Human Needs by Horta and adjusted by Garcia and Cubas. It is a study of methodological type developed in four stages: identification of empirical indicators to pregnant women through an integrative literature review; evaluation of empirical indicators and their relation to human needs by focus group; structuring of the second version of instrument by categorization of indicators and appearance and content validation of the third version of instrument by judges, by use of Delphi technique. The collection of data was the first stage in months from August to October 2014 in the Journal of Midwifery and Women's Health and Scopus, PubMed, Lilacs, CINAHL, Cochrane databases. The remaining steps were carried out from November 2014 to February 2015. For the focus group was counted with participation of six experts through two meetings. As for the judges, it was obtained a population of 63 and final sample of 51 judges divided into 46 basic health units of Municipal City Health Natal/RN, Brazil. The study was approved by the Research Ethics Committee of Universidade Federal do Rio Grande do Norte, under Protocol number 876.200. For data analysis of the first stage it was used descriptive statistics and results are presented in tables and charts. At that stage were identified 162 empirical indicators and, when they were related to human needs, 64 by them were on psycobiological, 97 on psychosocial and one (1) on psychospiritual needs. Regarding the second and third stages, data were treated by process of categorizing and analyzing the Content Validity Index. The indicators obtained a 100% validation index. In appearance and content validation phase of instrument non-validated items were excluded and other items obtained index above 70%. Furthermore, it obtained 99% content validity index in the second version and 95.7% in the third version of the instrument as a whole and, therefore, validated tool. This instrument contains Health Institution, pregnant woman and her partner identification data, information on the human needs of the pregnant and items pertaining to systematize the collection of pregnant couple data during prenatal care. By the conclusion of the study, nurse shall have an instrument to collect the data of pregnant couple in primary care innovative by considering psychobiological, psychosocial and psychospiritual pregnant needs and insert health and sociodemographic data of pregnant partner in the context of pregnancy. Also, the document will serve as a tool for teaching and research in obstetrical nursing.
