Pełny tekst źródłaAdvances in digital tools are transforming teaching methods in initial and professional training. Among them, high fidelity simulation for health is now key. Various studies show the value of using simulation in initial training, specifically for the acquisition of technical gestures (hard skills) and knowledge, and emotion management (soft skills) during acts. Thus, this thesis is part of the initial training in a physiotherapy institute based on an experiential approach. In this research-action we will endeavour, with occupational didactics, to apprehend the mechanisms triggered by simulation by comparing them to another method. Two axes will be considered. The first will focus through quantitative data collection on assessing acquisition of theoretical knowledge by our learners by simulation versus a practical work. The second, through the use of self-confrontation interviews, will attempt to understand the differences in students' clinical reasoning. Schema analysis will lead us to offer answers to our questions and point out teaching strategies. The conclusion to our research will consider the setting up of learning sequence adjustment resulting from the analysis of the interviews. We also propose as a result of this work, the creation of another technological tool that will interest the medical and paramedical community. To our knowledge, this is one of the few studies on simulation in physiotherapy linking the simulation approach and clinical immersion

Pełny tekst źródłaSammanfattning av ”Regn eller snö? En fråga om våta temperaturen” Noggranna prognoser beträffande nederbördstyp är väldigt viktiga inom många områden isamhället. Det finns därför ett behov att utveckla bra metoder att avgöra om nederbördenfaller som regn eller snö. Viktiga fysikaliska processer är avgörande för nederbördens och denomgivande luftens temperatur; processernas kritiska betydelse för dess fas har satts i fokus.De två största latenta värmeeffekterna, avkylning genom smältning och genomavdunstning/sublimation har betonats. Smältning av snöflingorna extraherar värme frånomgivningen och därmed sänks temperaturen. Avdunstning och sublimation erfordrar värmeför fastransformation vilket även här tas från omgivningen och därmed en kylande effekt somföljd. Dessa två latenta värmeeffekter har ibland kritisk betydelse för nederbördstypen vidmarkytan och detta diskuteras dels i en artikel om en vädersituation från Tennessee (Kain etal., 2000) där smälteffekten fick avgörande betydelse för nederbördsfasen vid markytan, dels istudier från Japan där betydelsen av avdunstning och sublimation på nederbördstypenbetonats (Matsuo and Sasyo, 1981). I det senare fallet tydliggörs isobara våta temperaturenoch dess betydelse som diskriminator mellan regn och snö. En numerisk vädermodell (HIRLAM) har använts för att studera olika typer avkondensationsscheman och deras betydelse för nederbörden under tre olika väderskeenden iSverige. Dessa är Rasch/Kristjánssons kondensationsschema, Sundqvistskondensationsschema samt en något ändrad variant av Sundqvists kondensationsschema dären subrutin för beräknandet av Tiw har implementerats och ersatt den vanliga temperaturen iden del av schemat som beräknar smältning av nederbörd i fast form. Smälttemperaturen harsedan satts till 0ºC. Resultatet visar skillnader mellan Rasch/Kristjánssons schema ochSundqvists schema beträffande total 12 timmars nederbörd (regn och snö). Vissa periodertenderar Sundqvists kondensationsschema att överproducera nederbörden medan under andraperioder är det Rasch/Kristjánssons schema, som överproducerar jämfört mednederbördsobservationer. Jämförelser mellan Sundqvists schema och Sundqvists schema medTiw visar att den senare producerar mer ackumulerad snömängd med de största skillnaderna iområden som avviker mest från mättnad (100 %). Där finner vi också större differensermellan den vanliga temperaturen och Tiw. Skillnaden blir större när vi ökar den totala tiden förackumulerad snömängd men dessa värden blir då också svårare att verifiera med snöanalyserfrån MESAN. Detta då snöanalyserna bygger på skillnader mellan aktuell och föregåendeobserverade snödjup. Detta behöver ej alls vara lika med den verkliga mängden nysnö somfallit, speciellt under mätperioder då det är plusgrader. Avvikelser från snöanalyserna kannoteras i både Sundqvists schema och Sundqvists schema med Tiw. I vissa regioner är docksnöprognosen från den senare något bättre. Det fysikaliskt korrekta värdet av Tiw = 0ºC somsmältgräns mellan regn och snö istället för den vanliga temperaturen, utgör grunden förintressanta framtida studier beträffande nederbörd och nederbördstyp.

Pełny tekst źródłaThis thesis analyses the role and impact of “a company internship” onto the development of professional scheme with “low skilled individuals” involved in alternative training. Our main target is, on the one hand, to highlight their profiles, their needs, as well as the representations they have of their trainings, their jobs, their professional schemes and, on the other hand, to identify and characterize their attitudes and the particular problems they are confronted with, when interacting with the different actors and with their business environment. We take for granted that the efficiency of the training system is connected with the biographical dynamics of each trainee together with the types of difficulties experienced in the context of alternative training. The research highlights that the problem for this group of the professional scheme as such but rather to doubts, even fears about their actual capacity to carry it out. The blocage seems even prior to the development of the scheme: they are having difficulties to overcome the biographical, personal, psychological and contextual obstacles. The expected efficiency could be obtained on two conditions: an institutional and pedagogical reorganization of the training system together with a better psychological and social accompaniment of the trainees

Pełny tekst źródłaDisinfection of swimming pool water is critical to prevent outbreaks of infectious diseases. However, disinfectants react with organic compounds present in water, including anthropogenic inputs (e.g. body fluids, sunscreens), leading to the formation of disinfection byproducts (DBPs) that have been linked to adverse health effects. Little is known about the fate of organic UV filters, present in sunscreens and personal care products, when introduced into chlorinated seawater swimming pools. The aims of the present study were to investigate the reactivity of five commonly used organic UV filters in chlorinated seawater, identify DBPs generated from the UV filters, analyze the occurrence of these DBPs in seawater swimming pools, and examine their genotoxicity. Chlorination experiments were conducted to analyze the reactivity of the UV filters oxybenzone (OXY), dioxybenzone (DIOXY), avobenzone (AVO), octyl methoxycinnamate (OMC), and octocrylene (OC) in reconstituted seawater. All the studied UV filters except OC were degraded in chlorinated seawater resulting in the formation of brominated DBPs. Based on the identified byproducts, transformation pathways were proposed. The occurrence of the identified DBPs was investigated in seawater pools. Several brominated DBPs were identified in seawater pool samples. The genotoxicity of bromal hydrate (BH), which was generated by the benzophenone UV filters OXY and DIOXY and detected in the investigated seawater pools, was assessed. BH induced genotoxic activity in the Ames test and in the comet assay. Overall, this study shows that UV filters can act as precursors for the formation of genotoxic DBPs in chlorinated seawater pools

Pełny tekst źródłaThe purpose of this approach to things invented by the painter andre elbaz is in-training and or therapy through the mediums of painting and acting. My research aims at giving a basis to reflection on symbolisation understood as a process. I therefore focused, first of all, on the notion of a device set up specifically for this in-training and or therapeutic approach. The instructions punctuating the way a pictodrama develops as to its pictural, verbal and theatrical aspects do indeed show that there is such a thing as a "symbolic circuit". This is precisely what i have tried to explore. All these questions lie at the very heart of the educational sciences, these being primarily concerned with how things "change" and "deteriorate", which "processes" can constantly be correlated with certain ways of proceding ("procedures"). Thus it is that a lengthy last part called "signs and symbols (specific views on symbolisation processes)" endeavours to explore the twofold notion of sign symbol. Education and or therapy revolve around this notion and thus the question of representation, of what being "real" means, of how cognition develops from sensory and motory activity and symbolic imagining cannot be eschewed

Pełny tekst źródłaThis sociolinguistic research addresses the links between the knowledge of the official language of the host country and the integration. Indeed, the knowledge of the language of the country of immigration is presented, even in the speeches of Council of Europe, as the key of migrants’ integration and we have been facing for about ten years, in all countries, the deployment of compulsory host language learning schemes intended to solve the integration difficulties for the newcomers. Yet, is it sufficient to speak the language of a country to integrate this country?This study carried out in four large countries of immigration in Europe (Germany, Belgium, France and United-Kingdom) deals with two aspects of the question.In the first part, the institutional conceptions of the integration by the language in these countries are examined and the four national linguistic learning schemes for migrants are compared. The second part of the research is based on a vast field study and analyses the various teaching practises of the languages and cultures and their impacts on the integration process. After cross-fertilizing the perspectives of these various educational processes, this thesis suggests, as a conclusion, a few didactic approaches to an integrative host language teaching and for training the teachers
Diese soziolinguistische Studie handelt sich um die Verbindungen zwischen der Kenntnis der Sprache des Gastlandes und der Integration. Die Kenntnis der Sprache des Immigrationslandes ist, eigentlich, bis in den Reden des Europarates, als sei sie der Schlüssel zur Integration der Migranten präsentiert und seit einem Jahrzehnten bemerken wir, in allen Ländern, die Umsetzung von obligatorischen Lehrprogrammen der Aufnahmesprache für Neuankömmlinge, die die Schwierigkeiten zur Integration lösen sollen. Ist es aber genug die Sprache eines Landes anzuwenden, um sich in diesem Land zu integrieren?Diese in vier großen europäischen Immigrationsländern durchgeführte Studie (Deutschland, Belgien, Frankreich und Gross-Britannien) beantwortet zwei Aspekte der Frage.In dem ersten Teil wird der Institutionelle Begriff der durch-die-Aufnahmesprache Integration in diesen Ländern behandelt. Diese erste vergleichende Analyse ermöglicht der vier nationalen für Migranten Sprachbildungssystemen nebeneinander zu setzen.Der zweite Teil der Studie stützt sich auf einer umfangreichen Feldstudie und analysiert die didaktische Praktiken der Sprache und Kultur des Gastlandes, und die Auswirkungen auf dem Integrationsprozess.Nachdem sie die Blickwinkel dieser verschiedenen Lehrmethoden berücksichtigt und die Gedanken von vielen Akteuren aus der Praxis gegenübergestellt hat, schließt sich diese Studie mit didaktischen Vorschlägen für eine integrative Bildung der Sprache des Gastlandes und für die Lehreausbildung ab

Pełny tekst źródłaSecondary organic aerosols (SOAs) represent a large fraction of fine particle matter, and contribute therefore to their impacts on human health, environment and climate. Understanding the sources, the evolution and the properties of SOAs is a challenge for the scientific community. These SOAs are produced by condensation onto preexisting aerosols of low volatility compounds formed during the progressive oxidation of gaseous organic matter. The objective of this thesis is to assess our knowledge of SOA formation processes. The methodology aims at (i) representing the processes in a deterministic and explicit model, (ii) comparing the modeling results with SOA measurements performed in controlled environments and (iii) examining the sensitivity of simulated results to poorly constrained parameters. The GECKO-A model (Generator for Explicit Chemistry and Kinetics of Organics in the Atmosphere) developed at LISA generates explicit chemical schemes on the basis of fundamental principles and provides the related kinetic and thermodynamic constants. Its ability to represent SOA formation was evaluated by comparisons with experiments performed in environmental chambers. The comparisons between modeled and measured final SOA yields show that the GECKO-A tool accurately reproduces the influence of molecular structure on the SOA formation. However, quantitative analysis shows that these yields are systematically overestimated. This suggests that processes are missing or misrepresented in the model, in particular the loss of gaseous organic compounds on the chamber walls. The implementation of this process into the model leads to (i) a decrease of the simulated final yields up to a factor 2, (ii) a change on SOA composition with a high sensitivity for the first generation species (nitrates, hydroxynitrates and carbonylesters) and (iii) a decrease in the SOA production rate when the mass transfer rate to the wall is increased. The model fails however to reproduce the dynamic of SOA formation. The results show that the uncertainties on particle surface accommodation and wall losses allow to encompass the experimental data. However, no unique configuration of these two parameters can be selected for all of the experiments

Pełny tekst źródłaThe gaseous oxidation of organic compounds emitted into the atmosphere leads to the formation of thousands of secondary organic compounds (SOC). A fraction of these SOC is low volatile, and can partition between the gaseous phase and the particulate phase, forming secondary organic aerosols (SOA). The SOA are a main component of the particles, representing between 20% and 80% of the total mass of fine aerosols. Therefore, SOA contribute to the impact of aerosols on the environment, in particular air quality and climate. The quantification of the SOA impacts is estimated using chemical-transport models (CTM). Comparisons with in situ measurements show that the spatial and temporal variations of SOA mass are not correctly simulated by CTM. In these models, the SOA formation is represented in a simplified way, using empirical parameterizations developed on the basis of observations performed in atmospheric simulation chambers. Improving the representation of organic aerosols in CTM is therefore required to diagnose the origin of air pollution by fine particles, improve the reliability of pollution episode prediction and assess the impact of aerosols on the environment. The objectives of this thesis are :• to explore the influence of environmental conditions on SOA formation and properties,• to develop a new parameterization of SOA formation based on a deterministic representation of atmospheric chemistry,• to evaluate this parameterization in CTM by comparison with in-situ measurements. Deterministic models represent the non-linearity of SOA formation processes. The model GECKO-A (Generator for Explicit Chemistry and Kinetics of Organics in the Atmosphere) is a numerical modelling tool that integrates the elementary data (kinetics and thermodynamics) from laboratory studies. In this thesis, oxidation scenarios representative of various environmental conditions were developed and GECKO-A was used to study the impact of environmental factors (temperature, NOx concentrations, solar radiations, etc.) on the formation and the properties of the SOA. On the basis of these simulations, a new parameterization for SOA formation was developed: VBS-GECKO. The evaluation of the VBS-GECKO in box model has shown a good reproduction of the organic aerosol (OA) concentrations with RMSE lesser than 20%.The VBS-GECKO was integrated into the CHIMERE CTM to simulate summer concentrations of OA over Europe. Simulated OA are significantly improved compared to the reference parameterization used in CHIMERE. The VBS-GECKO was also used to study (i) the sources and properties of SOA and (ii) different representations of emissions of semi-volatile and intermediate volatility organic compounds by road traffic

Pełny tekst źródłaCurrently, in organisations, much attention is given to workplace learning and more specifically, intentional, structured and organised learning on the job. Indeed, this kind of training seems to be more efficient and less expensive than off-the-job training.In our research, we study a specific workplace curriculum which has been developed by Entreprise & Personnel association. The aim of our research is to examine the efficacy of this curriculum.Our theoretical framework draws together the work of Billett (1995, 1996, 2001, 2006) one of leader scholars of the field of Workplace Learning and Pastré (1999, 2005, 2011), one of the key researchers of the francophone field vocational didactic. It allows us to formulate 2 hypothesis:- the curriculum facilitates learnings and in particular scheme transformation process;- this curriculum facilitates learning because it affords opportunities that engage the learner.The data gathering procedures was conducted in the French power distribution company ERDF. They include interviews and observations of 21 technicians. Our findings show that hypothesis n°1 is confirmed for all the participants, and hypothesis n°2 for most of them.Our research invites researchers to examine the efficacy of curriculum in terms of scheme transformation process, workplace opportunities and individual engagement. Our findings confirm the interest of workplace curriculum. At the same time, it invites professionals to think critically of reflexivity and learning transfer questions.Our research was conducted under a partnership between Paris Ouest University and ERDF. It was in part funded by the French national research agency

ZigBee is a standard of short rang wireless sensor network that is based on IEEE 802.15.4 standard designed by IEEE and the standard is designed by the ZigBee Alliance. ZigBee has the characters of low data rate, low power consumption, low cost, high reliability, high expansibility, and easy to deployment. Because of the characters, ZigBee is suitable to apply in the building automation, industrial control, personal health care, home security, environment monitoring, and consumer electronics, etc. In some of applications of ZigBee networks, their power are supported by a dry battery. Therefore, the efficient establishment of the ZigBee network is very important. For establishment of the ZigBee network, the tree-based topology is popular because the topology is easy to establish, easy to maintain, and more efficient. The ZigBee Alliance released the standard of establishment of tree-based ZigBee network in the ZigBee specification that only considers the link quality for frames received and the depth. Therefore, some of ZigBee devices serve too many child devices and the loading of ZigBee devices in the network are not balance. Because of the reasons, the battery will be consumed quickly and the service will be broken. This paper proposes an efficient tree formation scheme to improve the standard which is released by the ZigBee Alliance. The scheme considers the types of power supply and extends efficiently the service time of ZigBee network. Furthermore, the Markov chain is used to build the ZigBee system model and the weight function is used to establish the effective service network. At last, the result of experiments will prove that the efficient tree formation scheme improves efficiently the loading of ZigBee devices and makes the ZigBee devices with electricity or solar power energy to have an opportunity to be the ZigBee router. Because of the condition of power, our proposed the scheme will have a longer service time than the standard which is released by ZigBee Alliance.

Image-schemas are derived from everyday bodily and social experiences. Since image-schemas structure our conceptual systems, we can have an embodied understanding of the conceptual world. In addition, image-schemas stem from perceptual and motor interactions. Due to the visual-gestural modality, the signed languages can give more concrete visual presentation to word formation. In this thesis, image-schemas are employed to investigate the word formation, with the goal of finding out the relation of image-schemas to word formation in Taiwan Sign Language. The basic image-schemas discussed in this thesis include PATH, CONTAINER, and PART-WHOLE image-schemas, while the subsidiary image-schemas include UP-DOWN, FRONT-BACK, FORCE, LINK image-schemas, and so on (Peña 1999, 2000, 2003). In this thesis, it is found that image-schemas can be used to account for the word formation and to interpret the meanings of the words in Taiwan Sign Language, and that many words are formed in accordance with the concept of the image-schemas, and the words sharing the same image-schema may denote similar concept or meaning. In addition, image-schemas can serve as the source domains for metaphorical mappings. For example, the UP-DOWN image-schema can be used as the source domain [VERTICALITY], which can be mapped onto the target domains like [QUANTITY], [QUALITY], and [STATUS] in Taiwan Sign Language. In addition, the conceptual metaphors such as MORE IS UP and LESS IS DOWN can be used to account for the formation of the words such as EXPENSIVE and CHEAP in Taiwan Sign Language.

In this thesis, we propose a routing mechanism that can mitigate the hot-spot problem of wireless sensor networks (WSNs) so as to extend the network lifetime. A WSN consists of a coordinator and many sensor nodes that periodically collect and report to the coordinator the sensed information. With such periodical transmission, a sensor node may exhaust its energy sometime if it has limited energy resources. Moreover, the energy consumption may further be aggravated by the hot-spot problem that commonly exists in most WSNs; that is, sensor nodes closer to the coordinator tend to relay more traffic, and will exhaust their power sooner than others. However, in most deployments of sensor networks, there exist some nodes, henceforth referred to as power-nodes, with fixed power supplies or easy to replace if malfunction. In this thesis, we propose a Backbone-Aware Network Formation (BANF) scheme to mitigate the influence of hot-spot problem. We use power-nodes to construct the backbone of a network and route information toward a backbone power-node first, or the coordinator if it is closer than other power-nodes. The power-nodes then route the traffic toward the coordinator through other power-nodes in the backbone. Therefore, BANF can distribute traffic loads to more spots (nodes near backbone power-nodes) and alleviate the hot-spot problem of WSNs. BANF has two features: (1) power-node based subtrees and routing, and (2) fault tolerance mechanism for power-node failures. Results from NS2 simulations show that BANF can prolong network lifetime about 193~310%, compared with ZigBee under various network topologies.

Bluetooth is a highly promising, low-cost, and low-power technology for short-range wireless communication. It is intended to replace existing cables between electronic devices. Bluetooth is an open specification. Even whose MAC protocol is designed for facilitating the construction of ad hoc networks, the issue of scatternet formation is left open in the Bluetooth Specification. Several researchers have proposed various solutions to form a scatternet. But most of them focused on static environment. This investigation presents an Adaptive Scatternet Formation Scheme (ASFS) for forming a scatternet for Bluetooth devices. Unlike earlier work, the proposed method is designed to work with dynamic environment where nodes can arrive and leave arbitrarily. ASFS consists of two parts, formation and maintenance. In formation, a coordinator is used to monitor the flow of nodes (arriving and leaving). This information is then used to assign the new arrival node a suitable role (Sub-coordinator, Master or Slave) to establish the link and assign it to an appropriate piconet. In maintenance, nodes are allowed to arrive and depart arbitrarily. The proposed method can incrementally extend the topology and heal the partitions of scatternet due to nodes arriving or missing. It dynamically adjusts the scatternet to minimize the number of piconets. We employed the Network Simulator, NS-2, as the simulation and analyzed the predicted results when nodes arrive in various conditions. The simulation result demonstrates that ASFS achieves better results than TSF (Tree Scatternet Formation, the algorithm is proposed by Tan et al.[17] and works well in dynamic environment) in packet transmission time and number of the piconets. The scatternet formation time reflects the advantage of parallel formation.

To cope with the needs of domestic economic development of public transportation, more roads and tracks are required to be built, renovated or widened to accommodate the increasing demand. Diminishing availability of land and the community value of the construction environmental protection, the project must consider a variety of environmental factors, therefore The well foundation provides a better construction method on gravel layer. This study is based on “The Rapid Transit System of Taichung City at CJ920 Section” which is the first project in Taiwan that uses a large scale of well foundation method in the metropolis area, focusing on the densely population and limited space of the metropolitan environment conditions, a well foundation build on gravel layer construction method is developed, at the same time inspecting the traditional well foundation method safety improvement and environment pollution prevention, the well foundation method applied on fine gravel layer sites can reducing acoustic noise, dust pollution and increasing construction safety, therefore, this method could be widely used in the metropolitan area by the civil and public projects.

In the short-range wireless communication and networking, Bluetooth is a promising technology, mainly used as a replacement for connected cables. Since the Bluetooth specification only defines how to build a Piconet, several solutions have been proposed to construct a Scatternet from the Piconets in the literatures. The process of constructing a Scatternet is called the Scatternet formation. The traditional scatternet formation has three defects: First, more power and time need to be consumed in order to construct the scatternet. Second, after the scatternet is formed, more power and bandwidth are required to maintain the connection of scatternet. Third, due to the restriction of topology, the communication between two nodes must be relayed through the bridge or master, even when they are in the communication range. In this thesis, we propose a novel method in the transmission ranges of all the other nodes to form temporary point-to-point piconet only when two nodes want to communicate with each other. When the communication is finished, the temporary point-to-point piconet is destroyed immediately. Two nodes in the communication range can communicate with each other directly without the relay node. Our On-Demand Point-To-Point Piconet Formation (ODP2P) scheme resolves the defects of traditional scatternet formation in communication range. In order to reduce the communication delay, every node owns its list to record the information of all nodes within the communication range. An on-event method maintains the list. Network performance analysis and simulations show that our method can reduce the routing path significantly, provide better utilization for Bluetooth personal area network (PAN), and maintain the range list efficiently.

In this study, hydrogen peroxide (H2O2) and persulfate (Na2S2O8) were utilized as in-situ chemical oxidation (ISCO) reagent to examine the dissolution of nickel (Ni) and chromium (Cr) from basalt based on bench-scale batch tests. The use of 10% H2O2 resulted in 0.017 mg/L of Ni and 0.002 mg/L of Cr in the reagent after 28 days’ Basalt dissolution tests. The dissolution effect of nickel is more remarkable than chromium. The use of 0.6 M Na2S2O8 resulted in 0.30 mg/L of Ni and 0.025 mg/L of Cr in the reagent after 28 days’ Basalt dissolution tests. The dissolution effect of metals from Basalt by using Na2S2O8 is more significant as compared with using H2O2. The use of Fenton-like reagent might quickly release Ni but not Cr from Basalt due to the initial catalytic effect of ferrous ions. Acidic catalysis of Na2S2O8 might enhance oxidation to cause more dissolution of Ni and Cr from Basalt. After 28 days’ Basalt dissolution tests, the dissolved Ni concentrations were growing with lowering pH, and the dissolved Cr concentrations didn’t show the similar trend. When ISCO remedy scheme was employed in Basalt formation areas, it is better to get rid of Na2S2O8 reagent or lower down H2O2 concentration to 1% to avoid of releasing Ni and Cr from Basalt formation.

Abstract In the development of Bluetooth networks, the network with single piconet size is not suitable to use in the current and future applications. Therefore, to combine a number of piconets into a Multi-hop scatternet system is an important issue. In the previous studies, there are many network topology structures to be presented, such as tree, star, ring and mesh topologies in which their features are with some advantages and weaknesses, respectively. However, the each node mobility and survival time does not take into account in the various topologies. In practice, the new arrival and departure nodes will increase the accesses and the reformation procedures within the network. It will result in serious degradation to the system performance. In this paper, we propose a new Hybird Multi-hop Scatternet Formation Algorithm (HMSFA) to solve the serious degradation to the entire system performance due to the arrival and departure problem of nodes. In the proposed system, the size of nodes is designed up to 50 nodes. We first choose the fixed nodes (or long survival nodes) to form the core piconet, the residual nodes to form the peripheral piconets. Therefore, the main structure of the core piconet is composed of nodes with hardly move and fixed power supply of equipment. In contrast, nodes in the peripheral piconets do not require the time characteristics. The system can be formed to maintain the flexibility, and both stability and practicality. After the network is formed, we combined with the characteristics of the two topologies which non-adjacent piconets match the star topology and adjacent piconets to form a ring topology. According to the characteristics, we propose a simple routing strategy. It can reduce the routing length of nodes in the multi-hop scatternet, and make the transmission time more efficient. In addition, it will be through the comparative analysis to prove that it is better than the efficiency of other network topologies and the performance of the average transmission path.

Pełny tekst źródłaCurrent theories of marriage and family formation behavior tend to rely on the assumption that people can and do consciously plan both fertility and marriage and post-hoc intentions should align with a priori reasons for action (Fishbein & Azjen 2010). However, research shows this is not always the case and researchers have labeled inconsistencies between pre- and post- reports of intentions and behavior as retrospective bias. Researchers such as Bongaarts (1990) have tried to create models that minimize this "bias".
The Theory of Conjunctural Action is a new model that can explain, rather than explain away, this "bias" (Johnson-Hanks et al. 2011; Morgan and Bachrach 2011). This new theoretical innovation uses insights about the workings of the mind to gain a greater understanding of how individuals report family formation decisions and how and why they might change over time. In this theory, individuals experience conjunctures (or social context which exists in the material world) and use cognitive schemas (or frames within the mind through which individuals use to interpret the world around them). These schemas are multiple and the set can change over time as individuals incorporate new experiences into them.
In this dissertation, I explore how and why pre- and post- reports of intentions may be different using insights from the Theory of Conjunctural Action. In the second chapter, using data from the NLSY79 and log-linear models, I show that there are considerable inconsistencies between prospective and retrospective reports of fertility intentions. Specifically, nearly 6% of births (346 out of 6022) are retrospectively reported as unwanted at the time of conception by women who prospectively reported they wanted more children one or two years prior to the birth. Similarly, over 400 births are retrospectively reported as wanted by women who intended to have no more births one or two years prior (i.e., in the prior survey wave). The innovation here is to see this inconsistency, not as an error in reporting, but as different construals of a seemingly similar question. In other words, women may not be consciously intending births and then enacting these intentions; rather women may have different schemas (or meanings) of prospective and retrospective measures of fertility intentions.
The next chapter uses this same data to test if women use different schemas to guide their reporting of prospective and retrospective fertility intentions. Again, using insights from the Theory of Conjunctural Action, I expect that different schemas (represented by different sets of variables) predict prospective and retrospective wantedness differentially. I show that retrospective reports of wantedness are guided more by age, marital status, education, job satisfaction, and educational enrollment at birth, while prospective wantedness was guided more by number of children desired and how many children they currently have. I show four logistic models predicting wanted verses unwanted births. I then compared the model fit of logistic models predicting prospective wanted verses unwanted births using the hypothesized prospective and retrospective schema variables and I did the same for the models of retrospective wantedness. I find that when women report retrospective wantedness, they are guided more by the hypothesized variables.
Finally, in the last empirical paper, because schemas are difficult to measure, I build a methodology, Network Text Analysis, to measure schemas and to understand the schemas surrounding marriage and fertility for low-income Blacks who have not yet had children. I use interview data from the Becoming Parents and Partners Study (BPP), a sample of young, unmarried, childless adults with low incomes. I use these data to explore schemas of childbearing and marriage. Contrary to previous findings that low-income parents do not link marriage and fertility and have different requirements for marriage and fertility, I find that marriage and childbearing are indeed linked and have similar requirements for low-income Blacks prior to childbearing. Low income Blacks hold quite traditional views about the role of marriage and its sequencing vis-à-vis fertility. I argue that the material constraints to marital childbearing may lead to non-marital births and thus respondents sever schemas connecting marriage and childbearing and adopt other schemas of childbearing to provide ad hoc justifications for their behavior.
