A methodology to measure coordination of business processes

Coordination of business processes is the management of dependencies where dependencies constrain how the tasks are performed. It has been traditionally done in an intuitive fashion, without paying much attention to the coordination load. Coordination load is being defined as the ratio between the time spent on coordination activities and the total task time. Previous efforts to understand and analyze coordination have resulted in mostly qualitative approaches to categorize and recommend coordination strategies. This research seeks to answer two questions: (1) How can we analyze process coordination problems to improve overall performance? (2) What guidance can we provide to reduce the coordination load of the process and consequently improve the organization's performance? Thus, this effort developed a quantitative measure for coordination load of business processes and a methodology to apply such measure. ^ This effort used a management simulation game to have a controlled laboratory environment enabling the manipulation of the task factors variability, analyzability, and interdependence to measure their impact on coordination load. The hypothesis was that the more variable, non-analyzable, and interdependent a process, the higher the coordination load, and that a higher coordination load would have a negative impact on performance. Coordination load was measured via the surrogate coordination time, and performance via profit. ^ A 22 x 31 full factorial design, with two replicates, was run to observe the impact on the variables coordination time and profit. Properly validated spreadsheets and questionnaires were used as data collection instruments for each scenario. The experimental results indicate that lower task analyzability (ρ=0.036) and higher task interdependence (ρ=0.000) lead to higher coordination load, and higher levels of task variability (ρ=0.049) lead to lower performance. However, contrary to the hypotheses postulated by this work, coordination load did not prove to be strong predictor of performance (correlation of -0.086). ^ These findings from the laboratory experiment and other lessons learned were incorporated to develop a quantitative measure, a tool (survey) to use to gather data for the variables in the measures, and a methodology to quantify coordination load of production business processes. The practicality of the methodology is demonstrated with an example.^

Adaptation in knowledge-based teams: An examination of team composition, leader sensegiving, and cognitive, behavioral, and motivational mechanisms

Organizations are increasingly relying on teams to do the work that has traditionally been done by individuals. At the same time, the environments in which these organizations and teams operate have been becoming progressively more complex and uncertain. These trends raise important questions about the factors that enable teams to adapt. In response to these questions, the current study sought to identify the cognitive, behavioral, and motivational processes and emergent states that promote a team's adaptation to unforeseen changes and novel events, and the team compositional characteristics and leadership processes that enabled these processes and emergent states. Two hundred twenty two undergraduate students from a large Southeastern University composed 74 3-person teams, and participated in a computerized decision-making simulation where each team formed the governing body (i.e., Mayor's cabinet) for two separate simulated cities, and made strategic decisions about city operations. Participants were randomly assigned to one of three roles, distributing expertise and creating mutual interdependence. External team leader sensegiving was manipulated through video recorded communications from an external team leader. Results indicate that team cognitive ability, achievement striving, and psychological collectivism, as well as external team leader sensegiving, were all related to the similarity and quality of team members' strategy-focused mental models (cognitive emergent states), and to the amount of information sharing among members (behavioral process). In turn, teams with more similar and higher quality mental models, and who shared greater levels of information, were found to have a greater ability to react and adapt to environmental changes, and to have greater levels of decision-making effectiveness. Results indicate a pattern of relationships consistent with hypotheses, and have important implications for organizations and knowledge-based teams charged with management responsibilities. Organizations should staff teams with the compositional characteristics that enable the development of similar and high quality mental models, and that promote information sharing among teammates. Similarly, organizations which train and develop leaders to engage in sensegiving behaviors enable team adaptability and promote enhanced decision-making effectiveness when faced with unforeseen changes and novel situations.

Making a Case for Global Education: Revisiting Pre-Service Teacher Lesson Planning Methods

Globalization has tightened the bonds of interconnectedness and interdependence among nation-states. Students are destined for careers that are profoundly international in nature. They need to develop global literacy aided by a global education. This paper mandates the need for global education as part of the pre-service teacher-training programs.

Isolation and characterization of the U1 and U2 snRNAs in the silk gland of the 5th instar larval stage silk moth Bombyx mori

In isolation and characterization studies, expression level U1 and U2 snRNA isoforms were obtained from the 5th instar larval stage silk gland (SG). The DNA content of the SG cells is approximately 200,000-fold higher compared to the usual (2N) somatic cells of B. mori due to endoreduplication. In this study, the existence of U1 and U2 snRNA isoforms in the SG of the organism is investigated. Bombyx mori U1 and U2-specific RT-PCR libraries from the silk gland were generated. Five U1 and eight U2 isoforms were isolated and characterized. Nucleotide differences, structural alterations, as well as protein and RNA interaction sites were analyzed in these variants. For the U1 snRNA variants, they were compared to the previously reported BmN isoforms. In all these U-snRNA variants, polymorphic sites do not predominate at the core of known functional sequences, which were interspecifically conserved. Variant sites and inter-species differences are located in moderately conserved regions. Free energy (ΔG) values for the entire U1 and U2 snRNA secondary structures and for the individual stem/loops domains of the isoforms were generated and compared to determine their structural stability. This will be the first time that U1 and U2 variants are shown specific for a development stage (larval) other than embryonic or adult. ^ Using phylogenetic analysis, evolutionary trees were generated for the U1 and U2 snRNAs using animal, plant, protista and fungal species. The resulting trees were boostrapped for robustness and rooted with the self-splicing RNA group II intron sequence from the cyanobacterium Calothrix. Using phylogenetic analyses, possible structural and functional evolutionary interdependence between the U1 and U2 snRNAs was investigated. ^

Development of test-based wind-driven rain intrusion model for hurricane-induced building interior and contents damage

Major portion of hurricane-induced economic loss originates from damages to building structures. The damages on building structures are typically grouped into three main categories: exterior, interior, and contents damage. Although the latter two types of damages, in most cases, cause more than 50% of the total loss, little has been done to investigate the physical damage process and unveil the interdependence of interior damage parameters. Building interior and contents damages are mainly due to wind-driven rain (WDR) intrusion through building envelope defects, breaches, and other functional openings. The limitation of research works and subsequent knowledge gaps, are in most part due to the complexity of damage phenomena during hurricanes and lack of established measurement methodologies to quantify rainwater intrusion. This dissertation focuses on devising methodologies for large-scale experimental simulation of tropical cyclone WDR and measurements of rainwater intrusion to acquire benchmark test-based data for the development of hurricane-induced building interior and contents damage model. Target WDR parameters derived from tropical cyclone rainfall data were used to simulate the WDR characteristics at the Wall of Wind (WOW) facility. The proposed WDR simulation methodology presents detailed procedures for selection of type and number of nozzles formulated based on tropical cyclone WDR study. The simulated WDR was later used to experimentally investigate the mechanisms of rainwater deposition/intrusion in buildings. Test-based dataset of two rainwater intrusion parameters that quantify the distribution of direct impinging raindrops and surface runoff rainwater over building surface — rain admittance factor (RAF) and surface runoff coefficient (SRC), respectively —were developed using common shapes of low-rise buildings. The dataset was applied to a newly formulated WDR estimation model to predict the volume of rainwater ingress through envelope openings such as wall and roof deck breaches and window sill cracks. The validation of the new model using experimental data indicated reasonable estimation of rainwater ingress through envelope defects and breaches during tropical cyclones. The WDR estimation model and experimental dataset of WDR parameters developed in this dissertation work can be used to enhance the prediction capabilities of existing interior damage models such as the Florida Public Hurricane Loss Model (FPHLM).^

Effects of academic integration on the persistence and achievement of under-prepared college students

The purpose of this dissertation was to examine the effect of academic integration, defined in terms of instructor/student contact, on the persistence of under-prepared college students and the achievement of those who persist. The overall design of this study compared instructor-initiated contact with conventional contact. The dependent variables were persistence, achievement, motivation and anxiety. Information was collected by administering the College-Level Mathematics Test (CLM), the Perceived Affective Contact Questionnaire (PAC), the expectancy and anxiety components of the Motivated Strategies for Learning Questionnaire (MSLQ), a departmental final examination, and by accessing university records. The sample consisted of 130 college algebra students at a large, public university with a Hispanic majority. The main analyses consisted of a 2x2x2 ANOVA (treatment by ethnicity by gender) to test for differences in achievement, t-tests to compare motivation, anxiety and perceived affective contact scores for the two groups, Chi-square tests to assess differences in persistence, and Pearson Product-Moment Correlation to determine the relationship between pretest scores and achievement variables. Results indicated that neither instructor-initiated contact, gender nor ethnicity is related to persistence, motivation or anxiety. A significant disordinal interaction of treatment and ethnicity was observed, with Hispanic experimental students scoring significantly higher on a test of algebra achievement than Hispanic control students. Academic integration, defined in terms of instructor/student contact, has a positive influence on the achievement of Hispanic students. This may imply their positive responsiveness to the relational aspect of contact due to traditional cultural values of interdependence, acquiescence to authority and physical closeness. Such interactive feedback is a means by which students with these values are recognized as members of the university academic community, prompting increased academic effort. Training in contact initiation to promote academic integration is implied, by the results of this study, for instructors dealing with first year students, especially instructors at institutions accommodating instructional methods to the needs of diverse groups.

Do amanhecer ao crepúsculo: o ambiente inteiro por minhas narrativas

The matrix of this dissertation research permeates the design of complex environmental education. Its purpose is the realistic utopia of sustainability focused on the elucidation of a cultural model, a way of life that can guarantee the preservation of the living and non-living wight, to compose a world in which all coexist in harmony. To do so, thinking that model permeates the understanding that we are nature. This understanding can be evidenced both in Karl Marx in his book, the Economic and Philosophical Manuscripts says: "Nature is the essential body of the human being", and Joël de Rosnay, in his book The Symbiotic Man explains that we humans, "are the neurons of the earth." In this same perspective, Elisabet Sahtouris, in his book The Dance of the Earth, has pointed out how little is accurate to say that "there is life on Earth," because we are knowledgeable that our planet is a living organism, then there is the "life of the Earth ". Thus, we are part of this life, we are a part of the whole. With long experience in the environmental field, I seek the collective understanding that environmental education is a process belonging to all areas of knowledge, while margins for its subdivision occasion that begins the role of librarian I am, as a mediator of educational, cultural process, and disseminate information, is an environmental educator. Research conducted lead me to propose a revision of values and attitudes, from a certain reorganization of thought, an ecology of ideas and action, evidenced by readings of education and complexity, especially tuned to the writings of Edgar Morin. This thesis makes use of metaphor as a cognitive operator to emphasize the solar cycle, linking it to the development stages of this work. In summary, we have as a goal to emphasize the importance of the human condition, respect for nature and the principle of natural, cultural and social interdependence. In order for us to have a society that values relationships of solidarity with each other, respect and gratitude for living beings and Mother Earth. What leads me to converge, the reframing of the environment, understanding it as Integer Environment

Capital social e desenvolvimento de territórios: estudo multicasos nos territórios da cidadania do Rio Grande do Norte

This study aims to systematize elements for territorial development analyzing attributes of social capital present in the territories of Rio Grande do Norte. Unlike other studies about the subject, it is not intended to measure the stock of social capital, but rather to reveal the phenomenon of social organization and its implications, considering territories examined are already made around social capital structures. Case study were used as strategy research because it is enables to understand holistic features and significant events within the context of real life. For this research were selected representatives of public and social institutions involved in territorial collegiate specifically those of the governing core, selected from the more effective involvement of discretion in structure, functioning and meetings. The three territories have similar realities, are products of a public policy that is based on common criteria and present interdependence between categories of analysis of social capital. The presence or absence of any relationship - link, bridge or connection - influences the performance of territorial policy, affecting the social organization and fostering processes of access to information. In the cases at hand, despite the similarity of the general conditions of structure and function, the Apodi has qualities superior to the other. The presence of Dom Helder Camara project that articulates, in parallel to the Territory of Citizenship, the same actors of public policy with social mobilization capacity and effectiveness of actions, is able to encourage different development processes at Apodi. This can be explanatory factor, the tangent construct social capital, so that the territory present living conditions and better levels of development than the other two addressed here.

Processo identitário profissional: as experiências formativas de licenciandos do curso de Física - UFPI

In this research, we have as study object the identification process with the profession of students of the Undergraduate course for preparing professors for teaching Physics of the Federal University of Piauí. We start from the following question: - What relationships can be established among the senses given by the students to the group of the experiences lived in their initial formation and the identity construction as teacher? The presupposition is that the process of identification with the profession can contain formative experiences that are impossible to be reduced to the situations of disciplines learning. We considered that, in the development of the process of professional identification, the articulations and the connections that the students established with themselves, with the others - their formative teachers, managers - and with the world - the University, the public school - they should be understood in the interdependence relationships, consubstantiated in the experiences lived during the initial stage of their formation. Therefore, our objective is to understand the process of identification of the students with the teaching profession, based in the senses given to their formative experiences. In order to get this aim, we used the methodology of the Comprehensive Interview, and we chose as methodological and theoretical principles: the multi-referential theoretical framework, 'configuration and interdependence', the relationship among 'identity and alterity', the sensitive hearing and the 'intellectual craft'. The study is organized in two parts: the first, contains two chapters, that have introductory character. The second part is unfolded in five chapters, and it constitutes the development of the thesis. In the "paths", we revealed, starting from the actions and intentions that mobilized the students, processes involved in the choice of the course, and, this way, the initial identifications with the being an university student. We looked for to identify possible dissonances among the curriculum 'instituted and instituting', as well as the implications of its management of the formative experiences of future teachers. In short, we tried to capture, through the speeches of a group of students, the signs, the images and the senses of their formative experiences, which indicate as a vision of how their teaching profession is built. With this study, we sought to contribute for the researches on the field of degrees, taking as axis the formative processes that configure those courses. Finally, that the proposition of professor formation politics should be fundamentally based in internal demands, lived in the formative processes.

Discovering complex interrelationships between socioeconomic status and health in Europe: A case study applying Bayesian Networks

Studies assume that socioeconomic status determines individuals’ states of health, but how does health determine socioeconomic status? And how does this association vary depending on contextual differences? To answer this question, our study uses an additive Bayesian Networks model to explain the interrelationships between health and socioeconomic determinants using complex and messy data. This model has been used to find the most probable structure in a network to describe the interdependence of these factors in five European welfare state regimes. The advantage of this study is that it offers a specific picture to describe the complex interrelationship between socioeconomic determinants and health, producing a network that is controlled by socio demographic factors such as gender and age. The present work provides a general framework to describe and understand the complex association between socioeconomic determinants and health.

Que dit la science à propos des intelligences multiples?

Dans le débat sur l’unicité ou la multiplicité de l’intelligence, Gardner prend nettement position en faveur des intelligences multiples (IM). Son approche soulève toutefois au moins neuf critiques : la confusion entre l’intelligence et le talent, une rigueur scientifique insuffisante, l’absence de réelles nouveautés, le caractère arbitraire des critères utilisés, les problèmes de l’interdépendance des IM, du réel statut des IM, l’ignorance des résultats des approches factorielles et le refus de considérer les différences entre les groupes, de la mesure des IM. La validité des applications des IM dans le milieu scolaire peut également être mise en doute. En conclusion, nous nous interrogeons sur la raison du succès de la théorie des IM.

Common Bound: The Small Groups of Methodism

The system of small groups John Wesley established to promote a proper life of discipleship in early Methodist converts was, in many respects, the strength of the Methodist movement. Those who responded to Wesley’s initial invitation to “flee the wrath to come” were organized into large gatherings called “societies,” which were then subdivided into smaller bands, class meetings, select societies, and penitent bands. The smaller groups gave Wesley the opportunity, through a system of appointed leaders, to keep track of the spiritual progress of every member in his movement, which grew to tens of thousands by the time of his death in 1791. As Methodism shifted from renewal movement to institutional church in the nineteenth century, however, growth slowed, and participation in such groups declined rapidly. By the early twentieth century, classes and bands were virtually extinct in every sector of Methodism save the African-American tradition. In recent years, scholars in various sectors of the Wesleyan tradition, particularly David Lowes Watson and Kevin Watson, have called for a recovery of these small groups for purposes of renewal in the church. There is no consensus, however, concerning what exactly contributed to the vitality of these groups during Wesley’s ministry.

Over the last century, sociological studies of group dynamics have revealed three common traits that are crucial to highly functioning groups: interdependence created by the existence of a common goal, interaction among group members that is “promotive” or cooperative in nature, and high levels of feedback associated with personal responsibility and individual accountability. All three of these were prevalent in the early Methodist groups. Interdependence existed around a shared goal, which for Wesley and the Methodists was holiness. That interdependence was cooperative in nature; individuals experienced the empowering grace of God as they each pursued the goal in the company of fellow pilgrims. Finally, the groups existed for purposes of feedback and accountability as individuals took responsibility both for themselves and others as they progressed together toward the goal of holy living. Wesley seemed to instinctively understand the essential nature of each of these characteristics in maintaining the vitality of the movement when he spoke of the importance of preserving the “doctrine, spirit and discipline” of early Methodism. Analysis of some of the present-day attempts to restore Wesley’s groups reveals frequent neglect to one or more of these three components. Perhaps most critical to recovering the vitality of the early Methodist groups will be reclaiming the goal of sanctification and coming to a consensus on what its pursuit means in the present day.

Seawater carbonate chemistry and growth, calcification of Thoracosphaera heimii in a laboratory experiment

Ocean acidification is considered a major threat to marine ecosystems and may particularly affect calcifying organisms such as corals, foraminifera and coccolithophores. Here we investigate the impact of elevated pCO2 and lowered pH on growth and calcification in the common calcareous dinoflagellate Thoracosphaera heimii. We observe a substantial reduction in growth rate, calcification and cyst stability of T. heimii under elevated pCO2. Furthermore, transcriptomic analyses reveal CO2 sensitive regulation of many genes, particularly those being associated to inorganic carbon acquisition and calcification. Stable carbon isotope fractionation for organic carbon production increased with increasing pCO2 whereas it decreased for calcification, which suggests interdependence between both processes. We also found a strong effect of pCO2 on the stable oxygen isotopic composition of calcite, in line with earlier observations concerning another T. heimii strain. The observed changes in stable oxygen and carbon isotope composition of T. heimii cysts may provide an ideal tool for reconstructing past seawater carbonate chemistry, and ultimately past pCO2. Although the function of calcification in T. heimii remains unresolved, this trait likely plays an important role in the ecological and evolutionary success of this species. Acting on calcification as well as growth, ocean acidification may therefore impose a great threat for T. heimii.

El ritual en los "Textos de las Pirámides": sintaxis, texto y significado

Este trabajo pretende explorar la dimensión ritual en los Textos de las Pirámides, el corpus de literatura religiosa extensa más antiguo de la humanidad. La naturaleza variada de sus componentes textuales ha impedido que los egiptólogos comprendan en profundidad las complejidades de la colección y los contextos originales en los que estos textos (ritos) aparecieron. La aplicación de la teoría del ritual, principalmente la aproximación de la sintaxis ritual, ofrece a los investigadores un marco excelente de análisis e interpretación del corpus, su estructura y función. Sujeto a las reglas de la sintaxis ritual es posible exponer los múltiples niveles de significado en el corpus para la resurrección y salvación del difunto.
