Regional study on Women's unrecognized contribution to the economy

The findings and analysis of this study are based on desk review and secondary data to substantiate this growing phenomenon, especially among the female population. Further the recommendations that will be put forward in this study will be added to the literature and serve as a baseline for further study in the Caribbean region. The study is sectionalized as follows. Chapter one discusses in brief the demographics, social and economic profiles of Barbados, Dominica, Jamaica and Trinidad and Tobago. This chapter also examines the employment rate, gender and poverty, and the achievements and progress of member states as it relates to the MDGs especially goal number 3. Men are more likely to be employed in the formal sector than women, and earn higher wages and salaries in the labour market despite the fact women may have obtained tertiary level education. The literature showed that women are at home spending more time on child care and other household related responsibilities but this can still be considered employment. This chapter also addresses the achievements and progress of member states as it relates to the MDGs especially Goal 3. Chapter 2 identifies the literature review of related subjects for this study. Chapter 3 discusses the categories and type of labour activities in the informal economies in the Caribbean Region, for example, paid and unpaid work, time use, women working and their caring, responsibilities for their relatives, domestic workers being undervalued and under paid, street and market vendors, micro-enterprises the services sector and commercial sex workers. Chapter 4 examines the importance of social protection for those employed in the informal labour market and the self employed. Chapter 5 provides a preliminary analysis of the findings from this study. Chapter 6 details the preliminary conclusions and recommendations.

A cidade de Camilo: escravidão urbana em Belém do Grão Pará (1871-1888)

O objetivo desta dissertação consiste em analisar determinados aspectos da escravidão negra na cidade de Belém, entre 1871 (ano de promulgação da Lei do Ventre Livre) e maio de 1888 (quando a escravidão foi abolida). O foco da pesquisa está voltado para a “experiência humana” e o “cotidiano” de um contingente populacional, que, apesar de expressivo (pelo menos até meados da década de 1880), não costuma aparecer na historiografia sobre a Belém de fins do século XIX, comumente chamada de Belém da Belle-Époque. Elementos componentes deste contexto, como o boom da economia da borracha, a propagação das ideias de “civilização”, “modernidade” e “progresso”, e o crescimento da população livre, acabam não deixando espaço para os escravos que residiam e/ou circulavam pelos quatro cantos da cidade e matizavam sua paisagem. O processo criminal em que foi réu um destes escravos urbanos, Camilo João Amancio, será o fio condutor dos quatro capítulos deste trabalho, que abordam as seguintes problemáticas: a relação dos escravos com a polícia e a justiça; sua inserção no mundo do trabalho e no mercado urbano de escravos; os usos e significados do tempo de não trabalho de que dispunham; e as redes de sociabilidades que teciam com os mais variados indivíduos.

Cultura organizacional: uma análise da microempresa familiar informal

Analyze possible relationships between the bankruptcy and the family structure of informal micro-enterprises in Fortaleza city, Brazil. The analysis began with a research among micro-entrepreneurs who were beneficiaries of PROFITEC loans in bankruptcy and non-bankruptcy situation in 1997-1999 period. Evaluate whether the overlap of family and professional relationship inside the organizational structure of those micro-enterprises is a factor leading to bankruptcy. The comparative analysis divides the micro-enterprises into two groups: one that which had complied with the loan obligations (abiding firms) and another which had not (non-abiding firms). The analysis pointed out the familiar structure as having positive and negative influences over organizational work in both groups. The research also realized that those groups of family informal micro-enterprises do not recognize the professional problems related to the family, giving room for managerial conflicts related to the compliance, work time and use of profit. We cannot say that family structure of the informal microenterprises is the decisive cause for non-abidance, since there are also family firms which have the same disadvantages of both groups, but are complying with their obligations. The personal relationships in the informal family firms, however, define good practices and behaviors that definitely affect their operations.

Gerenciamento na construção civil - planejamento e controle: estudo de caso no planejamento físico de um empreendimento imobiliário

Given the high competitiveness in the construction industry, businesses became necessary in a management which reduce costs and delivery times, and is fundamental to running a compatible planning with the magnitude of each work order is the same make feasible the executor. When it comes to planning, one is including both the physical planning of the work, time and duration of the events, as well as the preparation of the cost thereof. There are numerous ways to run the management of works, then it is necessary, in most cases, the planning experience, in previous works, the engineer in charge, because with it he should know what strategy to take the work skirt as planned and designed. For a complete and efficient management, an initial study hard to prepare the physical and financial planning it is necessary, in order to make it real and consistent throughout the execution of the work. It is necessary also a hard monitoring of both the physical and the financial schedule in order to what was initially planned to be completed as close as possible. This paper shows a case study which uses some ways to the management be held with the course of planning, medium and short term, as well as the preparation of the initial budget of the work. Will also be presented as is performed physical planning of a real estate work

In-Flight Collision Avoidance Controller Based Only on OS4 Embedded Sensors

The major goal of this research was the development and implementation of a control system able to avoid collisions during the flight for a mini-quadrotor helicopter, based only on its embedded sensors without changing the environment. However, it is important to highlight that the design aspects must be seriously considered in order to overcome hardware limitations and achieve control simplification. The controllers of a UAV (Unmanned Aerial Vehicle) robot deal with highly unstable dynamics and strong axes coupling. Furthermore, any additional embedded sensor increases the robot total weight and therefore, decreases its operating time. The best balance between embedded electronics and robot operating time is desired. This paper focuses not only on the development and implementation of a collision avoidance controller for a mini-robotic helicopter using only its embedded sensors, but also on the mathematical model that was essential for the controller developing phases. Based on this model we carried out the development of a simulation tool based on MatLab/Simulink that was fundamental for setting the controllers' parameters. This tool allowed us to simulate and improve the OS4 controllers in different modeled environments and test different approaches. After that, the controllers were embedded in the real robot and the results proved to be very robust and feasible. In addition to this, the controller has the advantage of being compatible with future path planners that we are developing.

Dynamik und Klimatologie von diabatischen Rossby-Wellen

Der Wintersturm Lothar zog am 26. Dezember 1999 über Europa und richtete in Frankreich, in Deutschland, in der Schweiz und in Österreich ungewöhnlich hohe Schäden an. Lothar entstand aus einer diabatischen Rossby Welle (DRW) und erreichte erst wenige Stunden vor dem europäischen Kontinent Orkanstärke. DRWs weisen ein interessantes atmosphärisches Strömungsmuster auf. Sie bestehen aus einer positiven PV-Anomalie in der unteren Troposphäre, die sich in einer Region mit starkem meridionalen Temperaturgradient befindet. Die positive PV-Anomalie löst eine zyklonale Strömung aus, dadurch wird östlich der PV-Anomalie warme Luft aus dem Süden herantransportiert. Während des Aufstieg der warmen Luft finden diabatische Prozesse statt, die zur Bildung einer neuen positiven PV-Anomalie in der unteren Troposphäre (PVA) führen. DRWs entstehen unabhängig von PV-Anomalien an der Tropopause. Falls sie jedoch mit ihnen in Wechselwirkung treten, kann - wie im Falle von Lothar - eine explosive Zyklogenese daraus resultieren. Im ersten Teil wird die Dynamik einer DRW am Beispiel des Wintersturms Lothar untersucht. Es wird insbesondere auf das Potential einer DRW zur explosiven Zyklogenese eingegangen. Im zweiten Teil wird das Aufretreten von DRWs in ECMWF-Vorhersagen untersucht. Es werden Unterschiede zwischen DRWs und anderen PV-Anomalien in der unteren Troposphäre hervorgehoben. Die Dynamik von DRWs wird mit Hilfe eines ECMWF-"Ensemble Prediction System" (EPS) des Wintersturms Lothar untersucht. Die 50 Modellläufe des EPS starten am 24. Dezember 1999 um 12 UTC und reichen bis zum 26. Dezember 1999 um 12 UTC. Nur 16 der 50 Modellläufe sagen einen ähnlich starken Sturm wie Lothar vorher. 10 Modellläufen sagen am 26. Dezember keine Zyklone mehr vorher. Die Ausprägung der baroklinen Zone, in der sich die DRW befindet, ist ausschlaggebend für die Intensität der DRW. Weitere wichtige Parameter sind der Feuchtegehalt der unteren Troposphäre und der latente Wärmefluss über dem Ozean. Diejenigen DRWs, die sich zu am 25. Dezember um 12 UTC näher als 400 km am Tropopausenjet befinden, entwickeln sich zu einer starken Zyklone. Alle anderen lösen sich auf oder bleiben schwache Zyklonen. Es ist schwierig, diabatische Prozesse in Wettervorhersagemodellen abzubilden, dementsprechend treten Schwierigkeiten bei der Vorhersage von PVAs auf. In den operationellen ECMWF-Vorhersagen von Juni 2004 bis Mai 2005 werden mit Hilfe eines Tracking- Algorithmus PVAs im Nordpazifik und Nordatlantik bestimmt und in fünf Kategorien eingeteilt. Die fünf Kategorien unterscheiden sich in ihrer Häufigkeit, ihrer Zugbahn und ihrer Gestalt. Im Nordpazifik entstehen doppelt so viele PVAs wie im Nordatlantik. Durchschnittlich werden im Winter weniger PVAs gefunden als im Sommer. Die Baroklinität und die Geschwindigkeit des Tropopausenjets ist in der Nähe von DRWs besonders hoch. Verglichen mit anderen PVAs weisen DRWs eine ähnliche Verteilung des reduzierten Bodendrucks auf. DRWs können in etwa gleich gut vorhergesagt werden wie andere PVAs.

Percutaneous radiofrequency ablation of virtual tumours in canine kidney using Global Positioning System-like technology

What's known on the subject? And what does the study add? We have previously shown that percutaneous radiofrequency ablation guided by image-fusion technology allows for precise needle placement with real time ultrasound superimposed with pre-loaded imaging, removing the need for real-time CT or MR guidance. Emerging technology also allows real-time tracking of a treatment needle within an organ in a virtually created 3D format. To our knowledge, this is the first study utilising a sophisticated ultrasound-based navigation system that uses both image-fusion and real-time probe-tracking technologies for in-vivo renal ablative intervention.

MODELING AND PROTOCOL DESIGN FOR EMERGING WIRELESS SYSTEMS

Mobile Mesh Network based In-Transit Visibility (MMN-ITV) system facilitates global real-time tracking capability for the logistics system. In-transit containers form a multi-hop mesh network to forward the tracking information to the nearby sinks, which further deliver the information to the remote control center via satellite. The fundamental challenge to the MMN-ITV system is the energy constraint of the battery-operated containers. Coupled with the unique mobility pattern, cross-MMN behavior, and the large-spanned area, it is necessary to investigate the energy-efficient communication of the MMN-ITV system thoroughly. First of all, this dissertation models the energy-efficient routing under the unique pattern of the cross-MMN behavior. A new modeling approach, pseudo-dynamic modeling approach, is proposed to measure the energy-efficiency of the routing methods in the presence of the cross-MMN behavior. With this approach, it could be identified that the shortest-path routing and the load-balanced routing is energy-efficient in mobile networks and static networks respectively. For the MMN-ITV system with both mobile and static MMNs, an energy-efficient routing method, energy-threshold routing, is proposed to achieve the best tradeoff between them. Secondly, due to the cross-MMN behavior, neighbor discovery is executed frequently to help the new containers join the MMN, hence, consumes similar amount of energy as that of the data communication. By exploiting the unique pattern of the cross-MMN behavior, this dissertation proposes energy-efficient neighbor discovery wakeup schedules to save up to 60% of the energy for neighbor discovery. Vehicular Ad Hoc Networks (VANETs)-based inter-vehicle communications is by now growingly believed to enhance traffic safety and transportation management with low cost. The end-to-end delay is critical for the time-sensitive safety applications in VANETs, and can be a decisive performance metric for VANETs. This dissertation presents a complete analytical model to evaluate the end-to-end delay against the transmission range and the packet arrival rate. This model illustrates a significant end-to-end delay increase from non-saturated networks to saturated networks. It hence suggests that the distributed power control and admission control protocols for VANETs should aim at improving the real-time capacity (the maximum packet generation rate without causing saturation), instead of the delay itself. Based on the above model, it could be determined that adopting uniform transmission range for every vehicle may hinder the delay performance improvement, since it does not allow the coexistence of the short path length and the low interference. Clusters are proposed to configure non-uniform transmission range for the vehicles. Analysis and simulation confirm that such configuration can enhance the real-time capacity. In addition, it provides an improved trade off between the end-to-end delay and the network capacity. A distributed clustering protocol with minimum message overhead is proposed, which achieves low convergence time.

A Comparative Evaluation of Three Skin Color Detection Approaches

Skin segmentation is a challenging task due to several influences such as unknown lighting conditions, skin colored background, and camera limitations. A lot of skin segmentation approaches were proposed in the past including adaptive (in the sense of updating the skin color online) and non-adaptive approaches. In this paper, we compare three skin segmentation approaches that are promising to work well for hand tracking, which is our main motivation for this work. Hand tracking can widely be used in VR/AR e.g. navigation and object manipulation. The first skin segmentation approach is a well-known non-adaptive approach. It is based on a simple, pre-computed skin color distribution. Methods two and three adaptively estimate the skin color in each frame utilizing clustering algorithms. The second approach uses a hierarchical clustering for a simultaneous image and color space segmentation, while the third approach is a pure color space clustering, but with a more sophisticated clustering approach. For evaluation, we compared the segmentation results of the approaches against a ground truth dataset. To obtain the ground truth dataset, we labeled about 500 images captured under various conditions.

Complete digital workflow for the production of implant-supported single-unit monolithic crowns.

OBJECTIVES The aim of this case series was to introduce a complete digital workflow for the production of monolithic implant crowns. MATERIAL AND METHODS Six patients were treated with implant-supported crowns made of resin nano ceramic (RNC). Starting with an intraoral optical scan (IOS), and following a CAD/CAM process, the monolithic crowns were bonded either to a novel prefabricated titanium abutment base (group A) or to a CAD/CAM-generated individualized titanium abutment (group B) in premolar or molar sites on a soft tissue level dental implant. Economic analyses included clinical and laboratory steps. An esthetic evaluation was performed to compare the two abutment-crown combinations. RESULTS None of the digitally constructed RNC crowns required any clinical adaptation. Overall mean work time calculations revealed obvious differences for group A (65.3 min) compared with group B (86.5 min). Esthetic analysis demonstrated a more favorable outcome for the prefabricated bonding bases. CONCLUSIONS Prefabricated or individualized abutments on monolithic RNC crowns using CAD/CAM technology in a model-free workflow seem to provide a feasible and streamlined treatment approach for single-edentulous space rehabilitation in the posterior region. However, RNC as full-contour material has to be considered experimental, and further large-scale clinical investigations with long-term follow-up observation are necessary.
