Soutsos, Marios Nicou. "Mix design, workability heat evolution and strength development of high strength concrete." Thesis, University College London (University of London), 1992. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.308062.
Full textAbstract:
A literature survey of the properties and uses of high strength concrete, defined for this study as having a strength in excess of 60 N/tnm2, has shown that of prime need is a systematic, reproducible procedure for attaining high strength concrete. The "Maximum Density Theory", i.e. the requirement that the aggregate occupies as large a relative volume as possible, has been adopted as an approach to optimisation of the mix proportions. However, this does not consider the effect that the aggregate suIface area has on the requirement of excess paste for lubrication. To investigate the combined effect of void content and surface area, mixes with lower sand proportions than that required for minimum void content were tested for slump. The optimum sand proportion is the one that produces the highest slump, for a particular cement content. This procedure has been called: "The Modified Maximum Density Theory". Having thus optimised the cement and aggregate contents, partial cement replacement by mineral admixtures, at low water-cement ratios, has been investigated in order to assess: a) their contribution to long term strengths, b) their contribution to reducing the heat evolution of concrete mixes, and c) their effect on the workability of concrete. Condensed silica fume (at replacement levels of up to 15%) produced higher compressive strengths than ordinary Portland cement. Ground granulated blast furnace slag (at replacement levels of up to 30%) can be used without decreasing the 28-day strength. Replacement by 20% pulverised fuel ash resulted in a 15% decrease in the 28-day strength and equal strength to ordinary Portland cement concrete at ages beyond 56-days. Temperature measurements during hydration, under adiabatic conditions, have however shown that these replacement levels do not lower the temperature rise at a water-binder ratio of 0.26. The higher levels required for significant temperature reduction will also cause a significant reduction in the strength. To offset this ground granulated blast furnace slag (58%) and pulverised fuel ash (36%) in combination with 10% condensed silica fume 4 were used. These combinations reduced the temperature rise by more than 10°C while the reduction in the 28-day compressive strength was less than 15%. Partial cement replacement by pulverised fuel ash and ground granulated blast furnace slag improved the workability and therefore allowed a reduction in the superplasticiser dosage required for a given slump. The use of condensed silica fume reduces the workability at low superplasticiser dosages, but it has a water-reducing effect above a certain superplasticiser dosage. Results from these studies have been used to formulate guidelines for the proportioning of materials for producing high strength concrete.

Full textAbstract:
Research shows that risk factors may be useful clues for predicting students' potential for engaging in weapon-carrying behavior. Law makers on every level-federal, state, and local- deem the presence of weapons on school grounds to be a serious problem and a violation of school policy. A large, urban school system has put forth sustained and costly efforts to prevent students from carrying weapons to school; yet students continue to carry weapons to school in this district. The purpose of this study was to use archival data collected as part of the school system's everyday practice to identify risk factors for students carrying weapons to school. Bandura's social learning theory guided this quantitative ex-post facto study. Six risk factors related to students' weapon-carrying behavior were examined: gender, prior fights, suspensions, race, academic achievement, and time of school day/year. Risk factors were compared for identified weapon carriers (n = 605) and non-weapon carriers (n = 605) using chi-square tests and a logistic regression analysis. Results showed that gender, prior fights, suspensions, and race were significant risk factors for weapon carrying. Students in this district who received 5-14 suspensions had a 1 in 4 chance of being a weapon carrier. Males as well as Black students and White students were 3 times more likely to carry a weapon to school. A pattern of fighting also correlated with an increased incidence of carrying a weapon to school. These data may help this school district and other school districts like it to provide better prevention strategies and enhance policy decisions by identifying students who are at high risk of carrying a weapon on school grounds.

Downing, Dirk Johannes. "Development of a novel active muzzle brake for an artillery weapon system / Dirk Johannes Downing." Thesis, Potchefstroom University for Christian Higher Education, 2002. http://hdl.handle.net/10394/9715.
Full textAbstract:
A conventional muzzle brake is a baffle device located at some distance in front of the muzzle
exit of a gun. The purpose of a muzzle brake is to alleviate the force on the weapon platform by
diverting a portion of the muzzle gas resulting in a forward impulse being exerted on the recoiling
parts of the weapon. A very efficient muzzle brake unfortunately gives rise to an excessive
overpressure in the crew environment due to the deflection of the emerging shock waves.
The novel active muzzle brake of this dissertation is based on a concept developed by Qinetiq.
The novel technique involves the main brake chamber being closed for a very short period of time
after the projectile has uncorked from the barrel eliminating the main emerging shock wave from
developing to full strength with the result that the novel muzzle brake gives rise to a very low
overpressure. This has the advantage that the gun crew suffers from less strain to the ears and
vulnerable organs. Inherently the novel brake suffers a loss in efficiency due to the chamber being
closed for a while and a method had to be developed to improve the efficiency of the
conventional part.
This dissertation deals with the development of a novel active muzzle brake intended for a 155
mm artillery weapon, but scaled to an 88 mm 25 pounder G 1 as an interim phase. Several
constraints and requirements have been set regarding the physical properties and performance
criteria of the prototypes. The interim phase of the project was executed within three years in
which six prototypes were developed and evaluated. Major challenges in the development were to
design a control and restoring mechanism that would survive the harsh conditions at muzzle exit
and to enhance the efficiency. The establishment of linear movement of the closure mechanism
and friction springs as the restoring mechanism was a major breakthrough in this respect. The
first four prototypes were designed using empirical data and first order modeling as background
while a CFD technique was used to refine the last two prototypes.
Of the six prototypes developed, the first two were unsuccessful in demonstrating the novel
technique. The one was unable to survive the muzzle exit conditions and the control mechanism
on the second muzzle brake opened too soon. Of the remaining four, the last prototype passed all
the specified constraints and proved to be a candidate for the 155mm upgrade. Not only was the
structure robust enough, the general appearance of the novel muzzle brake is futuristic. This
prototype is also a candidate if a much more efficient muzzle brake, with similar overpressure
characteristics of a less efficient muzzle brake, is needed.MIng (Mechanical Engineering), Potchefstroom University for Christian Higher Education, 2003

Whelan, A. J. "The development of a warhead into an integrated weapon system to provide an advanced battlefield capability." Thesis, University College London (University of London), 2011. http://discovery.ucl.ac.uk/1318153/.
Full textAbstract:
This thesis addresses the topic of integration of weapons systems into communication networks to provide an advanced battlefield capability, with particular application to air launched and long range crew served weapon systems which may also be vehicle mounted. It considers the use of 'Military off-the-shelf' seeker, navigation and communication systems coupled with a novel tandem warhead system. This combination of 'low risk' technologies and a novel warhead system is intended to demonstrate a greater flexibility in weapon systems which could be exploited to reduce development risk, integration risk, qualification costs and increase target defeat capability across the wider more current target set. The use of a suitable communication and navigation system enabling integration of such a weapon system into a networked force was also investigated. This thesis is based on one area of research; Multiple Effects Weapons. Research is being undertaken by several nations on Multiple Effects Weapons. The aim of this research is not to provide a one weapon fits all solution, a panacea, the aim is to widen the utility of one system which could be employed in many roles. As yet no warhead system has achieved the types of effects that are being sought, although research and product development – particularly in the United States of America - continues. Therefore the United Kingdom government has sought to understand what technologies would be required to achieve a truly flexible warhead system which would enable defeat of large Main Battle Tanks, heavily armoured Infantry Fighting Vehicles, Soft Skinned Vehicles, infantry and urban structures. To this end numerical modelling, design and a demonstration programme of a MEW warhead system was performed. MEW systems are not only reliant on 'Smart' warhead systems, the application of sensors, fuzing and communication systems are crucial to enable suitable employment of a 'one size fits most' approach. The other important sub-systems which provide the link to the battlefield network are also discussed in this thesis, the inclusion of these well developed low risk technologies make it is possible to bring such systems into service in the near term with increased system flexibility. The integration of such a system relies on the current United States Department of Defense procurement strategy which includes development of the Joint Tactical Radio System radio system which will allow Ad-Hoc networking between platforms, weapons systems and commanders. Airframe and propulsion technologies are not discussed; they are outside of the scope of this thesis. The use of proprietary data from suppliers other than QinetiQ has been avoided as suitable permissions are not in place, this has limited the systems engineering aspects of this thesis to high level block diagrams which provide guidance on integration issues.

Full textAbstract:
This thesis describes the development of GAMA, (Gun Automatic Multiple
Ammunition), a unique, multi calibre, rapid firing weapon with the aid of
simulation and testing. Simulation at the time did not fully support the
contemporary sophisticated tool sets, and therefore a method was designed
to use simulation and experimental development interactively. Simulation
models were generated modularly whilst phasing it with the acquirement of
experimental test data.
Successes in the cross correlation of results progressively supported
simulation over the extensive use of testing experimental hardware.
Nevertheless, the knowledgeable use of simulation combined with
experimental processes supported the practice of calibrating models before
use. This prevented time wastage since unnecessary detail did not need to
be simulated.
Authenticated base line models provided an accredited tool throughout the
development of GAMA.
Using simulation judiciously and interactively with testing resulted in a
foundation for the expansion of GAMA, thus optimising its performance and
reliability whilst reducing time and cost.
The uniqueness in this project consists of the fact that no similar, multi-calibre
gun has existed in the world at the time, nor does it exist today. In
addition, many of the simulation techniques used were novel and specifically
designed for this project against the background of the world-wide arms
embargo against South Africa.Thesis (Ph.D. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2006.

Full textAbstract:
Approved for public release; distribution is unlimitedThis thesis integrates Concurrent Engineering (CE) or Design for Manufacturability into a government research and development agency. For new weapon concepts originating within government, CE is difficult to apply effectively within the policies and bureaucratic structures. This project describes a proposed structure for a development agency, using fuzes and the U.S. Army Fuze Division as a basis. Although the Fuze Division’s application of CE to date has been effective, much potential remains unreachable due to the Department of Defense (DOD) acquisition policy, with its series of incremental design phases. The proposed organization is arranged in teams according to professional/ engineering specialty. In addition, manufacturing engineering and fuze systems engineering groups are introduced. Integrated Product Teams managed by a member of the systems engineering group would draw from each of the specialized groups. This project illustrates that an agency can be organized to support and promote effective concurrent engineering within the limitations of the DOD acquisition policy. With this structure, manufacturing considerations will be deliberately integrated into every new fuze design, at all design phases. Although current policy may not allow skipping a phase, the Milestone B fuze will now be functionally operational and manufacturable, greatly reducing the design work remaining for Milestone C.

Chang, Genevieve. "Designing an effective user interface for the Android tablet environment." Thesis, University of Cape Town, 2015. http://pubs.cs.uct.ac.za/archive/00001024/.
Full textAbstract:
With over 1.3 million applications on the Android marketplace, there is increasing competition between mobile applications for customer sales. As usability is a significant factor in an application’s success, many mobile developers refer to the Android design guidelines when designing the user interface (UI). These principles help to provide consistency of navigation and aesthetics, with the rest of the Android platform. However, misinterpretation of the abstract guidelines may mean that patterns and elements selected to organise content of an application do not improve the usability. Therefore, usability tests would be beneficial to ensure that an application meets objectives efficiently and improve on user experience. Usability testing is an important and crucial step in the mobile development process Many freelance developers, however, have limited resources for usability testing, even though the advantages of usability feedback during initial development stages are clear and can save time and money in the long-run.
In this thesis, we investigate which method of usability testing is most useful for resource constrained mobile developers. To test the efficacy of Android guidelines, three alternate designs of a unique Android tablet application, Glycano, are developed. High-fidelity paper prototypes were presented to end-users for usability testing and to usability experts for heuristic evaluations.
Both usability and heuristic tests demonstrated that following the Android guidelines aids in user familiarity and learnability. Regardless of the different UI designs of the three mockups, Android guidelines provided an initial level of usability by providing familiarity to proficient users and an intuitiveness of certain patterns to new users. However, efficiency in building Glycano schematics was an issue that arose consistently. Testing with end-users and experts, revealed several navigational problems. Usability experts uncovered more general UI problems than the end-user group, who focused more on the content of the application. More refinements and suggestions of additional features to enhance usability and user experience were provided by the experts. Use of usability experts would therefore be most advantageous in initial design stages of an application. Feedback from usability testing is, however, also beneficial and is more valuable than not performing any test at all.

A computer code is developed using finite volume technique for solving steady twodimensional and axisymmetric compressible Euler and Navier-Stokes equations for
internal flows by &ldquomulti-block&rdquo
technique. For viscous flows, both laminar and turbulent flow properties can be used. Explicit one step second order accurate Lax-Wendroff scheme is used for time integration. Inviscid solutions are verified by comparing the results of test cases of a support project which was supported by ONERA/France for Turkey T-108, named &ldquo
2-D Internal Flow Applications for Solid Propellant Rocket Motors&rdquo
. For laminar solutions, analytical flat plate solution is used for planar case and theoretical pipe flow solution is used for axisymmetric case for verification. Prandtl turbulent flow analogy is used in a flat plate solution to verify the turbulent viscosity calculation. The test cases solved with single-block code are compared with the ones solved with multi-block technique to verify the multi-block algorithm and good similarity is observed between single-block solutions and multi-block solutions. For the burning simulation of propellant of Solid Propellant Rocket Motors, injecting boundary is used. Finally, a segmented solid propellant rocket motor case is solved to show the multi-block algorithm&rsquo

This master thesis deals with the subject of mass graves as a result of war and violence; how, where and why they are created, what they represent and how they are used throughout the Scandinavian Iron Age and Middle Ages. To analyze and discuss these questions, I have used nine case studies as well as several literary sources such as Beowulf, Tacitus and Jordanes. To further increase the depth of this discussion and to help us understand the mass graves themselves, I have also included subject of warfare in the form of a walkthrough of violence and social psychology. Together, these pieces have helped me form the basis for an analysis and discussion of the three acts I have created: The Ingroup act of deposition, The Outgroup act of deposition and the Triumph act of deposition.

Full textAbstract:
Vi lever i en värld där teknikutvecklingen går allt snabbare och till synes exponentiellt och oförtröttligt kommer att fortsätta öka. Hur detta påverkar Försvarsmaktens val av tekniknivå för framtida sensorförmåga för artillerilokalisering kopplat mot operativa krav, interoperabilitet och ekonomi blir extra intressant när radartekniken befinner sig i ett generationsskifte. Beprövad teknik, internationella och militära krav på en artillerilokaliseringsradar ställs mot ny radarantennteknik, svensk forskning och utveckling av Aktiva Elektroniskt Styrda Antenner (AESA). Syftet med denna uppsats är att undersöka huruvida ny teknik är ett nödvändigt tekniksteg för artillerilokalisering eller är "gårdagens" teknik lika bra eller kanske till och med bättre i vissa användningsområden och situationer? Är AESA ett nödvändigt tekniksteg för artillerilokalisering? Metoden för uppsatsen är en jämförande litteraturstudie d.v.s. en kvalitativ textanalys utifrån en given teoriram. Uppsatsen är också undersökande och beskrivande där jag har kopplat empiri genom studiebesök med intervjuer och informationsinhämtning hos bl. a Saab EDS, FMV samt FOI. Resultatet visar att den nya radartekniken tillför nya förmågor och kan förbättra sensorprestanda men att enbart nyttja AESA-teknik för artillerilokalisering blir både dyrt och exklusivt. Den aktiva antenntekniken lämpar sig även för multifunktionalitet vilket kan komma att ha en avgörande betydelse i framtiden.We are living in a world where technology development is accelerating and seemingly exponentially and tirelessly will continue to increase. How this will affect the Armed Forces' choice of technology for future generations of sensor capability regarding weapon location systems and related to operational requirements, interoperability and economics is particularly interesting when the radar technology is in a generation shift. Proven technology, international and military requirements for a weapon locating radar system are set against new antenna technology and the Swedish research and development of the Active Electronically Scanned Arrays (AESA). The purpose of this study is to investigate whether new technology is necessary for weapon locating systems or is "yesterday's" technology as good as, or maybe even better, in certain applications and situations than AESA? Is AESA technology a necessary step for weapon locating systems? The method of this paper is a comparative literature study, i.e. a qualitative textual analysis from a given theoretical framework. This essay is also investigating where I have linked theory with empirical data from interviews with Saab EDS, FMV and FOI. The results show that the new radar technology adds new abilities and can improve sensor performance, but to only use AESA technology for weapon locating purposes is both expensive and exclusive. The active antenna technology is also suitable for multi-functionality, which may play a crucial role in the future.

Full textAbstract:
The RAF has been undertaking Land Quality Assessments across the retained estate. As part of this study the author has been interested in the environmental hazard posed by disposal to land by burial and or burning of the Royal Air Force's WWII (World War 2) Chemical Weapons (CW) stockpile. The investigation describes a Hazard Rating strategy to address the potential contamination. The development of a novel method of screening sites using dogs is also described. The study charts the development of chemical weapons for use by the RAF and looked at the production and distribution of these weapons from factories to stations. Mustard gas was the major chemical weapon agent adopted by the United Kingdom government during this period. The 65 Ib Light Casing (LC) bomb was deemed to be one of the most potentially successful weapons in the CW arsenal. As of 1 April 1945 the total number of 65 Ib LC bombs manufactured for use in Northwest Europe was 389,937 of which 388,800 were available for use by the RAF and 1,137 were transferred to the USAAF. The study describes the problems of leakage especially with the Mk 1 variant and its associated Mk 1 wooden crate. It is highly likely that leaking weapons were buried on RAF sites and that by the end of the war a considerable quantity of mustard gas agent has potentially leaked into the ground. Mustard gas is likely to remain on stations. American weapons, distribution and potential storage sites have also been discussed.

A long period of economic and industrial development has allowed Taiwan to evolve into newly industrialized country (NIC). Simultaneously, the development of her major weapon systems has evolved from foreign weapons acquisition to independent development due to establishing research and development (R&D) capabilities. However, competitive pressure in the international arms market has finally led Taiwan to return to foreign acquisition, and consequently rapidly eroding her R&D capability. Balancing foreign acquisition and independent development is a policy analysis problem for Taiwan. This study applies the system dynamics methodology to construct a weapon systems development model for Taiwan. This model is used to analyze the impact of acquisition policy. The results indicate three major possible growth curves for weapon systems R&D capability based on alternative weapon systems acquisition policies.

Project management has been adopted and used by the majority of the enterprises, However, it always affected by the uncertain factors during the executive process, and becomes difficult to control the process and the schedule of the project’s research. Thus, lots of the project plans are lead to be postpone or fail. Therefore, how to control and mange the risks effectively, increase the project’s finish opportunity and achieve the project’s goal has become an important issue and work for the project management personnel. With the rapid developments and innovations of the military high-tech technology among every nation, the weapon system developed by our nations should fully use the high-tech techniques. The higher technique weapons have the higher risk during the research process. In spite of the administrator and technique personnel have made the extremely efforts to improve or advance the performance during the development process. However, lots of unpredicted problems still happened such as budget overspend, schedule delay, performance lower than expected and so on. So how to discover the problems earlier and reduce the risk happened probability have become an important process of the project risk management that can’t be ignored. The project risk management theory has been proved that it has premium effects using on the project’s cost, time, technique and quality control. It also has higher opportunity to make the project achieve the designated date, quality and budget goal. This thesis uses the method of Monte Carlo Simulation to do the quantitative analysis. It also abstracted and cited the essence of the project management processes from the “Project Management Body of Knowledge“, as the main idea among this thesis. According to the process of risk identification and risk evaluation and analyze by the Monte Carlo Simulation method. The weapon research and development project can be calculated as the expected cost, date and success probability. The method can also provide important references for the administrator to take the necessary process such as prevention, decrease, transference or acceptance to avoid failures.

Weimar, Rolf. "A Simplied Game Engine for a Game Development Course." Thesis, 2014. http://pubs.cs.uct.ac.za/archive/00000938/.
Full textAbstract:
The Video Game industry is maturing. Success in the video game industry relies on many things, including marketing, sound business practises, and top notch technical implementation. Games Engines are software systems that facilitate game production. The growth of the game industry has increased the demand for programmers trained in game development technologies. A simplified game engine, designed specifically for the game development courses which service the supply of graduates for the industry, could have many advantages.
This dissertation analysed the requirements of such a system. We found that such a game engine would need to be extensible, reusable, modular, be easy to learn, and be open source. It would also need to at least include graphics, audio, networking and pathfinding components. Our analysis found that no game engine currently exists that fulfills all these requirements.
We designed and implemented a game engine to fulll all these requirements. Our game engine is built around a module framework, where each task of the game engine is handled by a module. This modular design allows us to easily change functionality by adding, removing or updating modules. All source code of the engine is available, thus any part of the engine can be changed if needed. Open source also means the engine is free for all to use. Game engines also need to be reusable so that in the industry the development costs of creating an engine can be amortised multiple projects, but also in a university context it means that time students can continue to use the system across multiple projects.
The system was tested by having students complete game development tasks using our game engine, ModEngine, and another comparable game engine. We used lines of code as a measure of code complexity and completion time as a measure of performance. We found that there is a statistically significant reduction in both the lines of code and the completion time of student's ModEngine assignments versus the comparison. Our p value (the probability that the data was due to chance alone) for lines of code is 9.662776 X 10^(-5) and for completion time is 0.018. Students were also given questionnaires to complete where they were asked about their experience using both engines. ModEngine was found to be easier to learn and was simpler to use; students can more easily explore game development concepts with ModEngine and can get started working with it much more easily.

WMD (Weapons of mass destruction) pose the direct and serious threat to the United States and the international society. The possibility of terrorist organizations using chemical, biological, radio weapon, and nuclear weapons has dramatically increased in the last decade. The availability of critical technologies, the willingness of some scientists and others to cooperate with terrorists, and the ease of intercontinental transportation allow terrorist organizations to more easily obtain, manufacture and deploy WMD and execute an international WMD attack. In response to the increasing WMD threat to national security, it is essential to understand the necessary actions against WMD proliferation to prevent related weapons and manufacturing technologies from being exposed to people (groups) with ill intentions. This study explores the content and international proliferation of nuclear, biological and chemical weapons, the possibility of terrorists acquiring or using WMD, and international anti-proliferation mechanisms and effects. As a consequence of the 911 incident, the international collaborative efforts in preventing all kinds of terrorist activities have inevitably increased. The current strategic imperative of “economic security” of our country must be revised. The government should re-evaluate the threat to our national security in response to this incident, or operate under the existing task force, but enhance the roles of the Ministry of National Defense and the Ministry of Foreign Affairs or create a WMD prevention strategic force jointly formed by the two ministries so as to achieve the ultimate goal of strengthening the security in Taiwan.

A Model Development of Operational Test & Evaluation in Weapon System Supportability ABSTRACT The purpose of weapon system test and evaluation is to make sure that under real battling situation, it may actually meet the operational requirements and provides the evaluation results to the decision makers for making up their mind to put it in mass production and actual deployment. How to implement the test and evaluation work effectively, and ensure the weapon system performing its maximal effectiveness to meet the operational requirements, is a very important issue to establish a real modernized, technology-oriented Army owning its sovereignty of national defense. Supportability stands for the supported level of the weapon system and the effectiveness of its related supplying system. Because there are so many supporting elements and other complicated factors which can affect the supportability of weapon system, an effective and widely accepted evaluation standard was rarely developed and approved by both of the armed service users and researchers in the past. The purpose of this study is to develop a model of operational test & evaluation in weapon system supportability in the process of acquisition, and make up the insufficiency on theory foundation of the existing test and evaluation operational mode. It can immediately help the research and development institutes and armed service users to enhance the performance of existing test and evaluation operations. This study first set up the hierarchy structure of the weapon system supportability, and through interview with experts, questionnaire survey and Delphi method, decide concrete objective constructs and evaluation criteria — 8 major items and 121 sub-items of supportability. Next, questionnaire was issued to experts of logistics support and planning in the armed forces as well as the research and manufacturing institutes(Chung-Shan Institute of Science and Technology). According to the results of questionnaire, we applied fuzzy multiple attribute decision making method to transfer the subjective and vague opinions from the different groups into the priority weighting of all evaluation criteria of supportability. Due to different characteristics of operations, we found that there exists significant different preference of criteria weighting between armed forces. Besides, all of armed forces emphasized on the utilization and acquisition of the major support elements. On the contrast, the research and manufacturing institutes focused on functional analysis characters of those elements. The results can be provided for the R&D institutes to make appropriate modification on their policies which can further meet the supportability requirements of different armed services when developing a new system. . This research provides a standard procedure of operational test & evaluation. When evaluating an actual system, we must first constitute an expert evaluation team according to the operating characteristics and functions of this specific system. By doing some appropriate minor modifications of our model, we can easily develop a specific procedure to evaluate the supportability of this actual system. This study has opened a door for subsequent study for more complicated effectiveness analysis on supportability. After constructing the evaluating criteria and their related weightings, it will be our next first priority to develop the most appropriate evaluation criteria of supportability applicable to both of system development and maintaining phases.

Abstract Test and evaluation for any development weapon systems of Armed Force begins from concept refinement and is involved in acquisition management process. Prior deployment of developed weapon system, a complete development test and evaluation (DT&;E) must be taken to ensure contracting techniques and engineering needs are achieved. Then, proceed to Initial Operational Test and Evaluation (IOT&;E) phase. As for operational suitability, to verify whether the reliability specification value can meet operation need is the main concerned at this point. The purpose of this research is to expect that the test and evaluation professionals to perform statistical analysis with the most appropriate reliability model and present much more thorough and unbiased evaluation through exploration of different reliability analysis models, and use MIL-STD-781C to develop sampling test plan and chi-square distribution to find the interval estimation. Through assessing the airborne missile weapon system reliability specification values, to look for suitable reliability model for exponential distribution as a basis for decision-maker. The research result can be incorporated into reliability analysis operating procedure and reference for test implementation.

ABSTRACT In the knowledge economic age of 21st century, high-tech industry development is the key to Taiwan economic growth. Value added product is necessary for competitive advantage in an enterprise or organization. A successful company will dependent on their high value added new products. However the failure rate of the new product development is high. How to reduce the risks of new product development and improve their added values is an important challenge. In order to study the concept of product development and value chain, we refer to the documentation a case study from the national defense research center and other related literatures. The new product development procedures begin with new product identification, research and manufacture. Value analysis is done on every stage. Early value chain design and development reduce risks of hight cost new product and promote products value. Finally, we illustrate our model by a case study from the weapon system development of the Chung-Shan Institute of Science and Technology.

The dissertation discusses the issues raised by the artificial intelligence military weapon systems which challenged the International Humanitarian Law. First of all, the dissertation clarifies technical facts and the application scope of International humanitarian Law (IHL) for weapons(and weapon systems). The dissertation presents the art of Artificial Intelligence (AI) innovation which has made great achievement in different field and especially on military field, owing to the rapid progress on big data and cloud computing technologies in recent years. However, it brings about the new global risk and warfare type of mankind because sovereign states are increasingly interested in artificial intelligence applications for military weapon systems, such development of autonomous weapon systems which make it capable of undertaking tasks and missions or making for lethal decisions to execute such missions on its own, that is, weapons that are capable of independently selecting and attacking targets without human intervention and this raises international legal issues especially relating ethical problem on the prospect of the loss of human control over weapons and the use of force. The second part compares the positions, statements and policies on autonomous weapon systems of international organizations and states basing upon different references and cited materials, indicating the key legal and ethical issues in respect of artificial intelligence weapon systems also called autonomous weapon systems, lethal autonomous weapon systems, killer robots, or war robots. Thirdly, this dissertation further analyzes and discusses whether the current international humanitarian law fundamental principles, such as legal review of new weapon, distinction, proportionality and military necessity are sufficient to regulate the autonomous weapon systems per se and the methods or means of use in warfare. In addition, summing up my own advisements in chapter 6 which shaping the possible legal framework for solving existing legal gap on regulating autonomous weapon systems on the basis of international principles of humanity and disarmament in the future.

Achieving a state of balance is essential when developing a video game (Schell, 2019, “Game Mechanics Must Be in Balance,” para. 1). Despite this, game balancing is frequently overlooked in game development curricula (Schreiber, 2016, 00:30). This research describes the development and pilot study of a framework that junior game designers can utilize to gain valuable skills in the area of game balance. The framework produced by this research provides users with the ability to tune weapon parameters and see the effects these changes have on a first-person shooter deathmatch game in real time. Participants in the study utilized the framework to achieve three pacing and balance goals. Data regarding the weapon parameters selected by participants and information about the participants’ usage of the framework is described in detail. This study serves as the groundwork for future research focused on finding a method for teaching junior game designers about game balance.

This thesis primarily presents the development and improvement of the Permanent-Magnet Synchronous Motor (PMSM) servo drive for an air-defense gun weapon system to achieve fully digital motor control scheme based on digital signal processor (DSP). By using DSP accompanied with the power inverter stage and control algorithm, the control effects are improved so the smaller system size, lower system cost and high efficiency and reliability can be achieved. The objective is to implement a digital control scheme using built-in software module blocks and internal peripheral hardware interfaces which is based on the fixed-point digital signal processor. That is suitable for implementation of a PMSM speed control. In addition, applying the principle of field-oriented control which transforms a 3-phase stationary coordinate system into a 2-phase rotating coordinate system, it can greatly simplify the control circuits. Under this consideration, the control scheme of torque control is achieved by controlling the torque component of the stator current. The benefits of these methodologies are making system integration smoother, reducing debug and troubleshooting time and providing a higher degree of visibility inside the software. The eZdsp TMS320LF2407A single chip development system produced by Spectrum Company is applied to design and develop a PMSM digital control system.

Abstract Research and development（R/D）is the major resource for generating scientific knowledge and promoting the progress of technology; it’s also the foundation for enhancing the competition of enterprise. By the radical competition the enterprises are facing, they aggressively invest more research and development to increase their competitive capability. Even, they apply such achievement on product and service to create most profit margins. Nevertheless, the distribution of research and development resource had been recognized a crucial problem before enterprise starting research and development projects. The Offical Defense R/D institute is in charge the mission of national security and economic growth. Yet, the passing ten years, the withering of famous oversea defense company and their harsh need for expanding the foreign market which all together make the acquisition and channel of weapon system easily and much more than ever. Thus, the defense R/D institute have to know how to innovate high performance, low cost, fast deploy and intelligent function (cheap、better、fast、smart) under the circumstance of limited resource, external competition and insufficient defense budget. That is the institute’s important topic. To spot the key factors that affects the weapon system R/D project need further study. This paper is to construct an integrated analysis of the key factor of R/D project. Aiming the weighting coefficient and key factors of project itself and it is individual phase to make ranking. More, by the definition of management, given the analysis and study, provide the decision maker the reference for decision evaluation and resource distribution. According to the theoretical basis and published paper of experts from domestic and oversea; put the characteristics of weapon system development. Herein we summarize the organization factors, technology factors, resource factors and exterior factors as fundamental level. Then, these levels evolve into 17 related criteria for constructing an analytic model. We design query sets by the above factors and designate the expertise in defense R/D, general university and military educational school as group. Finally, we choose Analytic Hierarchy Process to decide the weighting coefficient of decision process. The result of research comes up with conclusion that the top two ranking factors are high level manager support and customer requirement. In conceptual design phase the priority of the fist two items is technology capability and the correlation with organizational goal. In demonstration and validation phase the priority of the fist two items is high-level manager support and human resource. In engineer development phase the priority of the fist two items are financial resource and customer requirement. In this research, we found the technology capability is the major factor in every phase. The reason is part of the weapon is limited by export license. In situation key technology cannot be acquired, so technology is regarded as most crucial factor. The other hand, the customer requirement takes much shares of the weighting. The reason is that the CSIST’S main customers are armed forces. Recently, weapon source is widely open; the idea of” fight with what you own” had changed to “fight with what you need”. That is a customer-oriented development policy. Thus, the customer requirement had been regarded an important factor.

Through the realism perspective in harmony with the angles of balance of power, security dilemma and deterrence theory, this research discusses the mutual relationship between nuclear weapons and national economy, politics, military, psychology and technology. In light of the diversification of how nuclear weapon affects national power, the research analyzes the factors influencing state’s development of nuclear weapons and the interaction between global environment and nuclear weapons in order to discover the acting, reacting, tending and expanding forces. It is then followed by the analysis of PRC’s strategic development of nuclear weapon. During the research process, it has discovered that states who owned nuclear weapons are all under significant influences of security dilemma both during and after the cold war era. This has caused nations continuously seeking the balance of power in order to maintain their survival and development. Therefore, factors affecting the progress of national strategic nuclear development including environment, restrictions, strategy and inspiration only change slightly. Utilizing the same research method to explore and analyze PRC’s development of nuclear weapon can generalize the developing factors of PRC’s nuclear strategy, and understand its mindset about nuclear weapon. Since the beginning of the 21st century, triggered by America’s global strategy, PRC seeks strategy that is in line with its national development and long-term defense needs, therefore its regular military power can be continuously expanded and upheld. In the future, PRC has a strong intention and capability to continuously enhance its nuclear force, complete the nuclear weapon structure, and improve the effectiveness of multi-layered deterrence in order to possess the global nuclear deterring capabilities.

The business environment and the technology change dramatically day by day, the criteria for the survival of an enterprise become stricter. The key elements of the past prominence may hinder the growth in the future. The advantageous position of the past faces overthrowing challenges. The alliance among companies adds fuel to the intensity of competition. Under the circumstances, an enterprise has to adopt effective strategies to save itself from collapsing. To ensure its competitive advantage, the core processes have to be reengineer and such sources as organization, manpower, materials and finance must be used properly. Among them, the management of materials is one of the most important steps to lower the cost and improve the substance. The purpose of this research is to apply the systematic thinking approach－TOC （Theory Of Constraints）to a defense weapon development and research institute in Taiwan. The strength and weakness of its material management system is first discussed. Implementation plan is then presented step-by-step using TOC methodology.

Para essa investigação, foi aplicado uma tarefa computadorizada e adaptada do Teste de Identificação de Armas (Payne, 2001; WIT), sendo que ainda foi realizado uma entrevista para colher informações sobre o contato dos participantes com pessoas de diferentes grupos raciais. Participaram 25 crianças caucasianas que relataram ter pouco contato com pessoas Afrodescendentes. Os resultados demonstraram que no bloco em que não havia restrição de tempo para a resposta, os participantes classificaram de uma forma precisa e rápida mais armas do que ferramentas, independente da face que antecedia esse objeto. Mas quando as respostas deveriam ser apresentadas até 700 ms eles foram mais rápidos em classificar os estímulos Face Negra e Arma do que Face Branca e Ferramenta. De um modo geral, quanto a entrevista, as crianças apresentaram ter uma atitude mais positiva em relação ao grupo de Caucasianos e mais negativa em relação aos grupos de Negros e Asiáticos.

For this research, were applied a computerized task that was adapted from the Weapon Identification Task (Payne, 2001; WIT), and were also conducted an interview to collect information about the participants’ contact with people of different racial groups. Participants included 25 Caucasian children who reported having little contact with people of African descent. The results show that during the blocks in which there were no time restrictions for responses, the participants classified more guns than tools with more accuracy and speed, regardless of which face preceded the object. But when the responses had to be given in up to 700 milliseconds, the participants were faster to classify the stimuli black faces and guns than white faces and tools. According to the interview, in general children have a more positive attitude toward the Caucasian group and a more negative attitude toward Black and Asian groups.

After Xi Jinping defined the "92 Consensus" as "one country, two systems", he showed the ambition to complete the "great unification and the Chinese renaissance" by invading Taiwan. There are two points of time to attain the goals, one is in 2020, the 100th anniversary of the Chinese Communist Party (CCP), and the other in 2049, the 100th anniversary of the People Republic of China (PRC). The reunification should be finished by 2020 or 2049, then the situation of Taiwan will be more dangerous. The situation of North Korea is just like Taiwan. North Korea lost its "nuclear umbrella" after the collapse of the Soviet Union. It not only faces the military threats from the United States and South Korea, but also suffers isolation and economic sanctions from the international community. In addition to implementing the "Brinkmanship strategy", North Korea got economic assistance from neighboring countries by military provocations, and even successfully developed nuclear weapons without considering the objection from the United States and South Korea. To tackle this, the United States not just put harder economic sanctions, but also executed joint- military exercises with South Korea to deter North Korea’s developing its nuclear weapons. The United States failed to the "nuclear non-proliferation" policy in Northeast Asia with the sixth successful nuclear test of the North Korea. In the past, in order to strike back at the mainland China, Taiwan also began to develop nuclear weapons in the 1960s. However, it failed in the intervention from the United States. In 1988, Chang Sian yi, deputy director of the Institute of Nuclear Research of the National Chung-Shan Institute of Science and Technology, betrayed to the US and assured that Taiwan was about to successfully develop nuclear weapons. Therefore, the U.S. sended nuclear group to Taiwan and terminated the programs and destroyed related facilities. The United States has always adopted a "fuzzy strategy" in the America-Sino-Taiwan relationship. Without effective US security promise, Taiwan had no choice but to developing nuclear weapons to deter the Mainland China and also ensure national security. If pro-US and democratic Taiwan owns nuclear weapons, under the rational leaders between both sides of the strait, it is possible to avoid a war by " mutual destruction assurance" and maintain the status quo of cross-strait peace.

Companies very often establish subsidiaries in other countries in order to find cheaper labour, qualified employees and/or be close to customers. In the IT industry, companies are opening Development Centres abroad, but the talk of implementing a Development Centre is associated with several challenges. As prior literature has not be examined the subject, this dissertation investigate the difficulties that a multinational company faces when implementing a Development Centre abroad and how overcome these difficulties. The study is based on an IT company with headquarter in Denmark, which unsuccessfully has tied to implement a Development Centre in Romania. 28 employees at all levels of the organisation at the headquarters are interviewed in order to investigate what went wrong. The research found a multinational company faces 15 different issues when implementing a Development Centre abroad and suggests several actions ti deal with each of them, The main difficulties discovered include differences in culture, language, institutional conditions, process, and especially difficulties related to physical distance across boarders and resistance from the employees. in order for a company to overcome these difficulties, focus should be put on aligning processes and culture by creating distributed teams, being constantly present at the Development Centre, ensuring face-to-face meetings, establishing lateral networks and having enough people involved in the implementation process. Furthermore, a company should understand the institutional and cultural differences between the sites, be transparent, abolish differential treatments and recruit the right employees.As empresas muitas vezes estabelecem subsidiárias em outros países para encontrar mão de obra mais barata, funcionários qualificados e/ou estar perto de clientes.

Como a literatura prévia não examinou este assunto, esta dissertação investiga as dificuldades que uma empresa multinacional enfrenta ao implementar um Centro de Desenvolvimento no estrangeiro e como superá-las. O estudo é baseado numa empresa de IT com sede na Dinamarca, que tentou, sem sucesso, implementar um Centro de Desenvolvimento na Romênia. 28 funcionários provenientes de todos os níveis tanto da organização sede como no Centro de Desenvolvimento são entrevistads para investigar o que deu errado. A pesquisa descobriu que uma empresa multinacional enfrenta 15 questões dferentes ao implementar um Centro de Desenvolvimento no estrangeiro e sugere várias ações para lidar com cada uma delas. As principais dificuldades descobertas incluem diferenças de cultura, idioma, contextos institucionais, processo e, principalmente, dificuldades relacioandas à distância física entre fornteiras e resistência dos funcionários. Para que uma empresa supere essas dificuldades, deve-se focar no alinhamento de processos e cultura, criando equipas distribuidas, estando constantemente presente no Centro de Desenvolvimento, garantindo reuniões presenciais, estabelecendo redes laterais e com o envolvimento de pessoas suficientes no processo de implementação. Além disso, uma empresa deve entender as diferenças institucionais e culturais entre os locais, ser transparente, abolir tratamentos diferenciais e recrutar funcionários certos.

Cooperation between countries has become the key element in securing financing for the development of the poorest countries with little capacity to mobilize the needed capital. However, this traditional architecture of development cooperation has evolved rapidly. New actors, new dimensions of development, new modalities and aid mechanisms, and new regulatory frameworks for their effectiveness and efficiency are emerging. The expended capital is consistently considered insufficient and the results keep on not emerging. In the process of building the latest framework for post 2015 development, the mobilization of resources and the effectiveness of their allocation appears again as crucial aspects. In this context, this dissertation tries to evaluate the role that financing mechanisms and practices, established in the new post 2015 development framework, can have in the paradigmatic evolution of development cooperation. Through a qualitative methodology, the main aspects about the development industry, from the end of the 1940s, are approached in a succinct and critical way. On the other hand, the analysis focuses on how the resources and mechanisms are managed to help the achievement of the outlined goals and in their added value for development. The future of the development industry goes through its renewal and innovation in the face of its constant failures, under the risk of being outdated. The post-2015 development financing scenario looks to be the crucial solution to finally achieve the much-desired development.

The results of the multiple regression analysis demonstrated that transformational leadership is a significant predictor of employees’ approach crafting behaviors, which in turn is significant in explaining work engagement levels. In addition, the significance of autonomy and workload as moderators of the relationships presented is verified. Finally, given the positive impact of approach crafting behaviors on work engagement, it is concluded that these behaviors should be encouraged by leaders.

Previous studies have perceived psychological detachment from work during off-job
time as an important recovery strategy allowing employees to recover from job stressors.
Psychological detachment is defined as an individual’s sense of mentally disengaging from
work while physically absent from it. Increasing levels of workload contribute to a lack of
psychological detachment from work during off-job time. Therefore, this study examines an
integrative view of how a moderation of supervisor support, and a mediation of work
engagement – which in turn is influenced by indirect sets of effects of moderations of emotion
regulation and neuroticism – help predict psychological detachment. In addition, we examine
the outcome of burnout from employees’ ability to psychologically detach from work. We
tested our hypotheses in a cross-sectional study with a sample of 546 employees from a public
service organization. Multiple regression analysis showed that workload, supervisor support,
and work engagement were significant predictors of psychological detachment. Additionally,
psychological detachment from work is significant to explain employee’s burnout and it
decreases in the presence of high levels of work engagement. Moreover, concerning practical
implications, it is crucial to provide adequate supervisor support, carefully understand if it is
imperative to reduce or increase work engagement, and promote interventions that facilitate
employees’ detachment from work.Estudos anteriores defendem o distanciamento psicológico como uma importante estratégia de recuperação, permitindo aos colaboradores recuperar de fatores indutivos de stress no trabalho. O distanciamento psicológico é definido como a capacidade de um indivíduo se desvincular mentalmente do trabalho enquanto fisicamente ausente do mesmo, com a particularidade de que o aumento da carga de trabalho dificulta o distanciamento psicológico. Neste sentido, o presente estudo examina uma visão que integra os efeitos de uma moderação de suporte do supervisor e uma mediação de work engagement. Esta mediação, por sua vez, é influenciada por conjuntos de efeitos indiretos de moderações de regulação emocional e neuroticismo, no distanciamento psicológico de um colaborador. Foi ainda examinado o burnout como resultado do distanciamento psicológico do trabalho. As hipóteses foram testadas num estudo transversal, com uma amostra de 546 colaboradores de uma organização de serviço público. A análise de múltiplas regressões mostrou que a carga de trabalho, o suporte do supervisor e work engagement são preditores significativos do distanciamento psicológico. Adicionalmente, o distanciamento psicológico é significativo na explicação do burnout nos colaboradores e diminui perante níveis elevados de work engagement. Por fim, no que diz respeito às implicações práticas, é crucial fornecer suporte adequado do supervisor, entender se se deve reduzir ou aumentar work engagement, e promover intervenções que facilitem o distanciamento dos colaboradores do trabalho.

O presente estudo tem como objetivo fornecer evidências empíricas da relação entre uma Liderança "Engaged" e o "Burnout" nos trabalhadores. Para percebermos essa relação analisámos o papel que as Exigências do Trabalho tinham na relação entre a Liderança "Engaged" e o "Burnout".
Como a variável Exigências do Trabalho é muito vaga, decidimos ser mais rigorosos e utilizar na nossa análise, exigências específicas. A escolhida para fazer a análise final foi os Conflitos Interpessoais. Com base nestas variáveis, Liderança "Engaged", Conflitos Interpessoais e "Burnout", formulámos um modelo de mediação, que afirma que os Conflitos Interpessoais (Exigências do Trabalho) medeiam a relação entre uma Liderança "Engaged" e o "Burnout" nos trabalhadores. Este modelo foi testado com uma amostra de 219 participantes. Os resultados das análises efetuadas mostraram que a Liderança "Engaged" está negativa e significativamente correlacionada com o "burnout" nos trabalhadores, e este por sua vez, é totalmente explicado pelos Conflitos Interpessoais (Exigências do Trabalho). Os resultados evidenciaram ainda que, a Liderança "Engaged" está também, negativa e significativamente correlacionada com as Conflitos Interpessoais. Verificou-se, portanto, que a Liderança "Engaged" é um preditor na redução dos sintomas de "Burnout", através das Exigências do Trabalho.The present study aims to provide empirical evidence of the relationship between an Engaged Leadership and Burnout in workers. To understand this relationship, we analyzed the role that Job Requirements had in the relationship between Engaged Leadership and Burnout. As the Job Requirements variable is very vague, we decided to be more rigorous and use specific requirements in our analysis. The one chosen to make the final analysis was the Interpersonal Conflicts. Based on these variables, Engaged Leadership, Interpersonal Conflict and Burnout, we formulated a mediation model, which states that Interpersonal Conflict (Job Requirements) mediate the relationship between Engaged Leadership and Burnout in workers. This model was tested with a sample of 219 participants. The results of the analyses showed that Engaged Leadership is negatively and significantly correlated with burnout in workers, and this in turn is fully explained by Interpersonal Conflict (Job Requirements). The results also showed that Engaged Leadership, is also, negatively and significantly correlated with Interpersonal Conflicts. Therefore, it was found that Engaged Leadership is a predictor in reducing Burnout symptoms through Work Requirements.

The learning approach and trainees’ expectations change throughout time due to generational characteristics, furthering the need to innovate new ways to train employees within organizations. Taking advantage of the technological development and digital orientation of the current workforce, gamification has proven to be an effective approach to learning purposes. This method incorporates game design elements into non-game environments, such as learning scenarios, aiming to improve motivational levels and, therefore, promote training effectiveness.
The present research aims to study user experience satisfaction and how could it impact training effectiveness. Furthermore, training motivation is analyzed as a mediator on this relation, as well as work engagement and open-mindedness in moderation roles.
A sample of 128 respondents allowed researchers to understand the strong correlation between gamification, measured through the user experience satisfaction, and training effectiveness. Additionally, the research showed that training motivation is crucial in making the first relationship happen. Moreover, work engagement and open-mindedness do not seem to have significant influence as moderators in the relationship described.
To build up gamified application for training, many variables should be taken into consideration when choosing the right gamification elements to include. These variables include concepts such as participants’ needs in regards to course content and training purpose. Additionally, these processes require organizations to be aware of the Human Resources policies and practices that should be adjusted to improve training and development methodologies.A abordagem de aprendizagem e as expectativas dos formandos têm vindo a alterar-se ao longo do tempo, devido às características geracionais, trazendo a necessidade de encontrar novas abordagens para formar os colaboradores nas organizações. Beneficiando do desenvolvimento tecnológico e da orientação para o digital, a gamificação tem vindo a dar provas de ser uma abordagem eficaz para fins de aprendizagem. Esta metodologia incorpora elementos de "design" de jogo em ambientes de não jogo, como contextos de aprendizagem, com o objetivo de melhorar os níveis de motivação e, consequentemente, promover formações eficazes. Este estudo pretende analisar a "user experience satisfaction" e qual o seu impacto na training "effectiveness". Posteriormente, a training motivation é analisada enquanto mediadora desta relação, sendo o "work engagement" e a "open-mindedness" estudados como moderadores. Uma amostra de 128 inquiridos permitiu perceber a forte correlação entre a gamificação, medida através da "user experience satisfaction", e a "training effectiveness". Para além disso, o estudo mostra que a "training motivation" é crucial para permitir a primeira relação. Adicionalmente, o "work engagement" e a "open-mindedness" parecem não ter uma influência significativa enquanto moderadoras da relação descrita anteriormente. De forma a implementar aplicações gamificadas, diversos fatores devem ser considerados ao selecionar os elementos de jogo certos a incluir, como as necessidades dos participantes no que diz respeito ao conteúdo e ao propósito da formação. Posteriormente, estes processos requerem a consciência das organizações acerca das políticas e práticas de Recursos Humanos que devem ser adaptadas para melhorar as metodologias de formação e desenvolvimento.

Full textAbstract:
GAYME is a transmedia story-telling world that I have created to conceptually explore the dynamics of queering game design through the development of varying game prototypes. The final iteration of GAYME is @deadquarewalking'. It is a documentary game and a performance art installation that documents a carless, gay/queer/quare man's journey on Halloween to get to and from one of Orlando's most well-known gay clubs - the Parliament House Resort.
"The art of cruising" city streets to seek out queer/quare companionship particularly amongst gay, male culture(s) is well-documented in densely, populated cities like New York, San Francisco and London, but not so much in car-centric, urban environments like Orlando that are less oriented towards pedestrians. Cruising has been and continues to be risky even in pedestrian-friendly cities but in Orlando cruising takes on a whole other dimension of danger. In 2011-2012, The Advocate magazine named Orlando one of the gayest cities in America (Breen, 2012). Transportation for America (2011) also named the Orlando metropolitan region the most dangerous city in the country for pedestrians. Living in Orlando without a car can be deadly as well as a significant barrier to connecting with other people, especially queer/quare people, because of Orlando's car-centric design. In Orlando, cars are sexy.
At the same time, the increasing prevalence in gay, male culture(s) of geo-social, mobile phone applications using Global Positioning Systems (GPS) and location aware services, such as Grindr (Grindr, LLC., 2009) and even FourSquare (Crowley and Selvadurai, 2009) and Instagram (Systrom and Krieger, 2010), is shifting the way gay/queer/quare Orlandoans co-create social and sexual networks both online and offline. Urban and sub-urban landscapes have transformed into hybrid "techno-scapes" overlaying "the electronic, the emotional and the social with the geographic and the physical" (Hjorth, 2011). With or without a car, gay men can still geo-socially cruise Orlando's car-centric, street life with mobile devices. As such emerging media has become more pervasive, it has created new opportunities to quarely visualize Orlando's "technoscape" through phone photography and hashtag metadata while also blurring lines between the artist and the curator, the player and the game designer.
This project particularly has evolved to employ game design as an exhibition tool for the visualization of geo-social photography through hashtag play. Using hashtags as a game mechanic generates metadata that potentially identifies patterns of play and "ways of seeing" across player experiences as they attempt to make meaning of the images they encounter in the game. @deadquarewalking also demonstrates the potential of game design and geo-social, photo-sharing applications to illuminate new ways of documenting and witnessing the urban landscapes that we both collectively and uniquely inhabit.
'In Irish culture, “quare” can mean “very” or “extremely” or it can be a spelling of the rural or Southern pronunciation of the word “queer.” Living in the American Southeast, I personally relate more to the term “quare” versus “queer.” Cultural theorist E. Patrick Johnson (2001) also argues for “quareness” as a way to question the subjective bias of whiteness in queer studies that risks discounting the lived experiences and material realities of people of color. Though I do not identify as a person of color and would be categorized as white or European American, “quareness” has an important critical application for considering how Orlando's urban design is intersectionally racialized, gendered and classed.M.F.A.

interaction between techno-complexity and both levels of self-efficacy were statistically
significant in predicting exhaustion. These results revealed that higher level of status conflict

Estudos anteriores concluíram que as exigências e recursos do trabalho desempenham um papel importante na explicação da exaustão nos trabalhadores. Neste estudo, 172 professores universitários chineses participaram através da resposta a um questionário. Este estudo transversal teve como objetivo analisar como a autonomia, o conflito de estatuto e a complexidade tecnológica podem ter impacto na exaustão emocional utilizando o modelo JD-R e verificar de que modo a autoeficácia pode moderar estas relações. Os resultados mostraram que a autonomia estava negativamente associada à exaustão, porém, o conflito de estatuto e a complexidade tecnológica estavam positivamente relacionadas com a exaustão. Os resultados revelaram também um impacto significativo da interação entre autonomia e a autoeficácia elevada na exaustão. Adicionalmente, a interação entre a autoeficácia baixa e o conflito de estatuto foi significativa na previsão de exaustão. Além disso, a interação entre a complexidade tecnológica e os dois níveis de autoeficácia foram estatisticamente significativos na previsão da exaustão. Estes resultados revelaram que níveis mais elevados de conflito de estatuto e de complexidade tecnológica estavam associados à exaustão quando a autoeficácia era baixa. No final do estudo apresentam-se as implicações práticas dos resultados, as limitações e algumas sugestões para pesquisas futuras.

As tecnologias de informação e comunicação (TICs) estão cada vez mais presentes no nosso quotidiano, tanto no local de trabalho quer na vida familiar. Ainda que as TICs facilitem inúmeras funções no trabalho, estas também podem levar os utilizadores a experienciar technostress devido à sobrecarga, complexidade, privacidade e inclusão. O objetivo deste estudo é analisar a relação entre os technostressors, o conflito trabalho-família e as emoções negativas dos trabalhadores.
Desenvolveram-se as hipóteses de que os technostressors estariam positivamente associados ao conflito trabalho-família e às emoções negativas. Foi também considerado que o conflito trabalho-família mediaria a relação entre cada um dos technostressors e as emoções negativas. Por último, foi testada a hipótese de que a preferência pela segmentação iria moderar a relação entre cada um dos technostressors e o conflito trabalho-família. Os dados foram recolhidos utilizando um questionário no qual participaram 339 trabalhadores. Relativamente às duas primeiras hipóteses, os resultados mostram que apenas a sobrecarga e a complexidade estão relacionadas com emoções negativas, e que todos os technostressors, a saber, a sobrecarga, complexidade, privacidade e inclusão, apresentaram uma relação positiva com o conflito trabalho-família. Chegou-se ainda à conclusão de que o conflito trabalho-família medeia a relação entre cada um dos technostressors e as emoções negativas. Relativamente à preferência pela segmentação, como moderador, os resultados encontrados não suportam a hipótese formulada.
Neste estudo é sugerido que os technostressors podem contribuir para uma maior experiência de emoções negativas e a um maior conflito trabalho-família, pelo que são apresentadas algumas recomendações para as organizações implementarem, de modo a reduzir estes efeitos.The technologies concerning information and communication are more and more current in our daily life, both at the workplace and in family life. TICs make endless functions much easier, but they are also prone to take their users to experience technostress, owing to overload, complexity, privacy, and inclusion. The goal of the present study is the analysis of the relationship between technostressors, the conflict work-family and the negative emotions the workers were submitted to. The hypotheses, that technostressors might be, positively, associated with the conflict work-. family and the negative emotions were examined. It was also considered if the conflict work-family would mediate the relationship of the technostressors and the negative emotions. Finally, it was tested if the preference for the segmentation would somehow mediate the relationship of technostressors and the conflict work-family. The data were collected using a questionnaire with the participation of 339 workers. Considering the two first hypotheses, the results indicated that only overload and complexity were related with the negative emotions and that the technostressors, namely, overload, complexity, privacy, and invasion, showed a positive relationship with the conflict work-family. It was also reached the conclusion that the conflict work-family mediated the relationship between technostressors and the negative emotions. As for the preference for segmentation as a moderator, the results obtained did not support the hypotheses formulated. In this study it was also suggested that technostress could also contribute to achieve a greater experience of the negative emotions and a greater conflict work-family, that is why some measures were suggested to the organizations to minimize the effects.

A pandemia causada pelo vírus Sarscov-2, e as suas sucessivas variantes espalhadas pelo mundo provocaram um aumento do consumo de diversos produtos nomeadamente de Equipamentos de Proteção Individual (EPI), que assumiram uma função muito relevante a nível global, trazendo esta medida de segurança usada para conter a propagação do vírus uma maior complexidade em diversos sistemas.
Na Associação Regional de Saúde (ARS) de Lisboa e Vale do Tejo para o desempenho das tarefas diárias é obrigatório o uso de fatos cirúrgicos em certas funções. O elevado consumo deste tipo de materiais descartáveis fez com que tivessem um impacto ambiental muito significativo e a oferta por vezes não fosse suficiente face à elevada procura, por estes motivos outras alternativas devem ser consideradas.
A presente dissertação incide na redefinição do sistema logístico atual que permita a substituição de fatos cirúrgicos descartáveis por fatos cirúrgicos recicláveis, e consequente estudo dos impactos relacionados com estas medidas.
Com base na revisão de literatura é possível concluir que estas mudanças resultam num impacto positivo para as organizações que adotem este tipo de medidas quer em termos de conforto e segurança para os utilizadores e utentes, como a nível ambiental e económico. Para encontrar a solução ótima foram identificadas as variáveis-chave, definidas hipóteses e construídos diferentes cenários.
O custo mais baixo foi atingido pelo cenário que se traduz na triagem ser feita junto com a roupa da lavandaria, a lavagem ser feita na SUCH e o registo ser feito apenas após a lavagem.The pandemic caused by the Sarscov-2 virus, and its successive variants spread around the world, caused an increase in the consumption of several products, particularly Personal Protective Equipment (PPE) that assumed a very relevant role at a global level, with this safety measure being used to prevent the spread coming into a greater complexity in various systems. In the Regional Health Association (ARS) of Lisboa and Vale do Tejo for the performance of daily tasks the use of surgical suits is mandatory in certain functions. The high consumption of this type of single-use material has caused a very significant environmental impact, and the supply is sometimes insufficient, and for these reasons other alternatives should be considered. This dissertation focuses on the redefinition of the current logistics system that allows the replacement of disposable surgical suits by recyclable surgical suits, and consequent study of the impacts related to these measures. Based on the literature review, it is possible to conclude that these changes might result in a positive impact for organisations that adopt this type of measures, both in terms of comfort and safety for users, and at an environmental and economic level. To find the optimal solution, key variables were identified, hypotheses were defined and different scenarios were built. The lowest cost was reached by the scenario that results in the sorting being done together with the laundry, the washing being done in the SUCH and the registration being done only after the washing.

Num contexto de rápido crescimento das mulheres no mundo organizacional, nomeadamente das mulheres em cargos de liderança, torna-se importante compreender como elas se sentem dentro das organizações, especificamente, se se sentem compreendidas pelos restantes elementos da mesma estrutura organizacional. O estudo da assimetria da identidade interna é uma das ferramentas para abordar o tema e uma forma de enriquecimento da literatura em diversos domínios.
Apesar de já terem sido realizados, até ao dia de hoje, vários estudos com foco na liderança e género, a maioria não procura explorar o estado emocional e psicológico na interação com os outros. Ademais, este tópico está ainda pouco explorado em Portugal.
A presente dissertação é focada na assimetria da identidade interna das mulheres na liderança em organizações. Assim, o objetivo geral é explorar como é que as mulheres líderes em Portugal, nomeadamente Lisboa, se sentem numa cultura organizacional. Mais especificamente, é abordado se e como estas lidam com a assimetria da identidade interna, positiva e negativa. Para tal, foram realizadas cinquenta e uma entrevistas, tendo trinta e uma resultado válidas. Estas foram realizadas pessoalmente ou através de redes sociais e, seguidamente, analisadas e codificadas de modo a comprovar a sua validade.
Os resultados mostram que a maioria das mulheres entrevistadas sofrem de assimetrias da identidade interna, sobretudo, da assimetria negativa. Verificou-se também, que ao longo das suas carreiras profissionais há momentos em que as assimetrias que são mais propícias ao acontecerem. Porém, quando estas acontecem, acabam por ser resolvidas e ultrapassadas.In a fast-growth context of women in the organizational world, particularly in leadership positions, it becomes important to understand how these women feel within the workplace, especially if they feel understood by their peers in the same organizational structure. The internal identity asymmetry study is one of the tools used to approach the topic and a way to enrich the literature in diverse domains. Although several studies with a focus on gender and leadership have been conducted, most do not attempt to explore the emotional and psychological state of interactions with others. Furthermore, this theme is yet to be explored thoroughly in Portugal. This dissertation focuses on the asymmetry of women´s internal identity in organizational leadership. Accordingly, the objective is to explore how women with leadership roles in Portugal, specifically in Lisbon, feel regarding the asymmetry of the internal identity, either positive or negative. To achieve this, 51 (fifty-one) interviews were conducted, with 30 (thirty) valid results. The interviews were led in-person or through social media networks, later being analyzed and coded to prove their validation. The results show that most of the interviewed women have suffered from internal identity asymmetries, emphasizing the negative side of it. It was also verified that there are moments in the women’s career where these asymmetries are more common, and when they occur, they are eventually solved and overcome.

The complexity inherent to burnout, along with the dynamic nature of work context demands further research regarding the causes of this phenomenon. Emerging in the field of workplace aggression, incivility has proven to be harmful for both individuals and organisations. Hence, referencing the Job Demands-Resources Model, we hypothesised the connection of colleagues and customers´ incivility with the recently developed four-scale measure of burnout and the moderating effect of self-efficacy. Two studies were conducted - the first with data collected from a questionnaire with respondents from several companies (N = 225), and the second using the same method, with participants from a single public large organisation (N = 562). Study 1 revealed a positive link between workplace incivility perpetrated by colleagues and emotional exhaustion. However, the findings did not support the moderator effect of self-efficacy. In Study 2, workplace incivility perpetrated by customers and the other three dimensions of burnout (cognitive impairment, emotional impairment and mental distance) were incorporated. Both types of incivility were significantly related to all facets of burnout. Results, howbeit, did not support the moderation effect of self-efficacy in the relationship between workplace incivility perpetrated by colleagues and customers on emotional exhaustion. Workplace incivility perpetrated by colleagues with mental distance, emotional and cognitive impairment showed also to not be moderated by self-efficacy. In contrast, the impacts of workplace incivility perpetrated by customers on the three previously mentioned dimensions of burnout were found to be buffered by self-efficacy. Limitations and future research directions are discussed.A complexidade inerente ao "burnout" e o contexto dinâmico das exigências laborais exigem mais investigação das causas deste fenómeno. Emergente no campo da agressão em ambiente de trabalho, a incivilidade provou ser nociva para indivíduos e empresas. Consequentemente, a partir do Modelo de Recursos e Exigências no Trabalho, analisámos a relação entre incivilidade por colegas e clientes com uma recentemente desenvolvida medida de "burnout" de quatro componentes, e o papel moderador da autoeficácia. Dois estudos foram realizados - o primeiro, com dados recolhidos através de um questionário, provenientes de trabalhadores de diversas empresas (N = 225); o segundo, através do mesmo método, com participantes de uma só organização pública de grande dimensão (N = 562). O Estudo 1 demonstrou uma associação positiva entre incivilidade praticada por colegas e exaustão emocional. Porém, os resultados não validaram a moderação da autoeficácia. No Estudo 2, incorporámos a incivilidade no trabalho perpetrada por clientes e as outras três dimensões do "burnout" (défice cognitivo, défice emocional e distância mental). Ambos os tipos de incivilidade mostraram estar significativamente relacionados com todas as componentes do "burnout". Os resultados não apoiaram a moderação da autoeficácia na relação da incivilidade perpetuada por clientes e colegas e a exaustão emocional. Incivilidade no trabalho perpetuada por colegas com as três dimensões do "burnout" mostrou também não ser moderada pela autoeficácia. Em contrapartida, os impactos da incivilidade no trabalho praticada por clientes e as três anteriormente referidas dimensões de "burnout" demonstraram ser mitigados pela autoeficácia. Limitações e futuras direções para investigação são discutidas.

empregadores da sociedade, o mercado de trabalho no retalho caracteriza-se na literatura de
saúde ocupacional pela existência de um elevado conjunto de stressors, aliados a uma tendência
de baixos salários e horários irregulares.
Perante esta realidade, procurou-se através de uma abordagem qualitativa de análise
template desenvolver um estudo exploratório com base no Modelo JD-R que visasse analisar a
realidade deste sector em Portugal, assim como a recuperação dos seus trabalhadores.
Simultaneamente, perante a escassez de investigações que abordam os períodos de grande
afluência às lojas (ex.: Black Friday, saldos), este estudo procura simultaneamente perceber
quais as exigências e recursos característicos destes períodos específicos.
Após a análise de 15 entrevistas semiestruturadas, os resultados espelham um sector
com uma multiplicidade de exigências, destacando-se como principal fator de stress e de
Eventos Críticos o Contacto com os Clientes e o aumento significativo das exigências nos
períodos de grande afluência. Contrariamente, ao nível dos recursos denota-se uma tendência
para o seu decréscimo nesses períodos, impactando negativamente a recuperação dos
trabalhadores.
Finalizando, este estudo exploratório conclui a necessidade das organizações retalhistas
em desenvolverem políticas de criação e desenvolvimento de mais e melhores recursos no
sector do retalho. Perante a diversidade e aumento de exigências nos períodos de maior
afluência às lojas, esta forma possibilitará o desenvolvimento de melhores resultados

Presenting itself as one of society’s most employing sectors, the retail labour market emerges within the occupational health literature as a high set of stressors allied with a low salaries and irregular working hours’ tendency. In view of this reality, this study draws on a qualitative approach based on a template analysis in order to develop an exploratory research centered on the JD-R Model, seeking to analyze the reality of this sector in Portugal, as well as its workers recovery. At the same time, facing the lack of health and well-being investigations that examine peak periods (eg.: Black Friday, Sales), it is also this study’s goal to explore its specific demands and resources. After analyzing 15 semi-structured interviews, this research results establish a wide range of demands within the field Contact with Costumers and the increase of demands and Critical Events during peak periods arose as the main stressful variables. In contrasts, there is a pattern towards the decrease references of resources within high affluence periods, adversely impairing the employees’ recovery during this span. Concluding, this research displays the need for retail organizations to develop policies that build better resources. Given the variety of demands and its increase within higher affluence periods to stores, the increment of resources will enable the development of better economic outcomes based on greater health and well-being conditions for employees.

From this context, the present dissertation proposes to work this challenge with the use of
technology in the improvement of human conditions lived in refugee camps.
Several people were interviewed in order to ascertain the main difficulties experienced in the
European refugee camps. These people have direct access to these problems and therefore have the
knowledge and experience to opine on the subject, being able to point out possible solutions.
The results point to the urgency of resolving human conditions of dignity - privacy, access to
sanitary structures, safety in sleep and lack of occupation of the adults.
Based on literature and official documents’ research, frugal innovation - concept explored
throughout this study - is a constantly evolving concept, capable of satisfying needs at low cost,
sustainability and great quantities, being possible to fill the necessities of a great number of people.
3D printing and cork bricks have proved to be solutions that meet the concept defined as the basis
for this study. Both technologies may allow to solve many of the problems found at refugee camps,
and represent solutions that are sustainable, economical and easy to implement, requiring reduced
