The purpose of this study was to determine the various values that may be contaminating the military's communication and to describe the predominant levels of psychological existence. The design of the study involved a National Guard battalion that was composed of 432 personnel. The sample drawn was 280. Data was collected through the use of a values test. Comparisons of the differing scores of demographic variables formed the bases of the conclusions drawn in the study. The results were highly significant at the .0001 level. The data indicate much support to the past research done in the field of Value System Analysis. Much research is yet needed to fully describe the value levels in all military organizations. This investigation is the beginning.

<p>The current study empirically tested a model of sibling caregiving topic avoidance, including privacy rule criteria as predictors of topic avoidance and both relationship satisfaction and depression as outcomes of topic avoidance. Associations between topic avoidance and its predictors and outcomes were compared for primary and non-primary caregivers. Additionally, the study tested privacy expectations, including information ownership and caregiving talk preference, as moderators of the associations between topic avoidance and both relationship satisfaction and depression. The current study is grounded in communication privacy management theory, conceptualizing topic avoidance as a strategy for maintaining privacy (CPM; Petronio, 2002). Findings validate CPM propositions related to privacy rule development and privacy turbulence. Findings also further understanding of informal caregiving, sibling communication, and topic avoidance.</p> <p>Over 75% of all eldercare in the United States is provided by unpaid, non-professionals (Family Caregiver Alliance, n.d.). Providing unpaid care has been linked to diminished well-being, including negative physical and mental health effects (Cooper, Balamurali, & Livingston, 2007). However, some scholars argue that caregiving is only detrimental in particular circumstances with some caregivers experiencing more benefits than burdens (Roth, Fredman, & Haley, 2015). The current study proposes that sibling communication is a key factor in determining when caregiving is harmful. </p> <p>Specifically, the current study examines topic avoidance about parent well-being and sibling’s contributions to parental care, including predictors of topic avoidance and the association of topic avoidance with sibling relationship satisfaction and depression. The current study includes a pilot study of 207 participants to develop CPM measures of caregiving topic avoidance, benefit-risk analysis, and information ownership as well as a measure of caregiving involvement (including personal care, routine tasks, and emotional support). The resulting measures are utilizing in a main study of 415 participants, testing models of middle-aged siblings’ topic avoidance.</p> <p>Findings contribute to understanding of informal care, sibling communication, and CPM. Privacy rule criteria, including context, motivation, and risk-benefit analysis, were associated with topic avoidance. Surprisingly, gender and family culture were not strongly associated with topic avoidance. Topic avoidance resulted in relationship dissatisfaction and greater depression when topic avoidance did not align with privacy expectations, resulting in privacy turbulence. Differences emerged for primary caregivers compared with non-primary caregivers, including predictors of topic avoidance and direct effects of caregiving involvement on relationship satisfaction and depression. For primary caregivers, involvement in personal care was associated with greater depression, and involvement in emotional support was associated with less depression. Overall, findings further understanding of privacy management, caregiving, and sibling communication and provide interesting avenues for future research.</p>

The ability to understand the individuals that we deal with on a daily basis can give anyone who focuses on this knowledge a competitive advantage in today's business world. In today's fast paced and globally expanding business world, it is critical to explore innovative approaches that will facilitate the process and time it typically takes to establish business relationships. When it is imperative to quickly create a business relationship between individuals that are unknown to each other, identifying the city or region of the individual with whom a relationship is being formed and understanding that culture will help build a common ground which will facilitate and enhance the newly established working relationship. This paper shows how this can be achieved. / by Walter N. Burton. / Thesis (M.A.)--Florida Atlantic University, 2008. / Includes bibliography. / Electronic reproduction. Boca Raton, Fla., 2008.

無處不在的無線業務以其不斷增長的需求促進了對稀缺無線資源的高效利用。多年來，優化技術被廣泛地運用在無線資源分配的方案設計上，從而達到改善系統性能之目的。在此領域的大部分工作中，用於定義優化問題的系統參數被假設為精確可知。然而，實際的系統參數往往是時變且隨機的。忽略系統參數的不確定性極易導致資源分配決策偏離最優狀態，或者甚至違反系統運行約束而使分配決策不可行。 / 本論文提出了一套用於無線通信的動態資源分配的隨機優化框架。具體而言，本文抓住了不確定系統參數的隨機本質，從而建立結合實際的問題模型，並且開發了高效的算法，以獲得最佳的分配決策。本文將提出的框架成功地應用於三個很有前景的無線通信系統中：自適應正交頻分多址接入（OFDMA）系統，多輸入多輸出（MIMO）天線系統，以及位置感知網絡。每一個應用系統中都存在與實踐相關的挑戰，而這些挑戰則源自於傳統基於靜態優化的設計在提供滿意的服務質量（QoS）中遇到的困難。結果表明，使用隨機優化的動態資源分配，可達到了更加穩健的QoS性能，並且顯著增強系統的實用性。 / 在自適應OFDMA系統中，本文提出了一套“慢適應“的最優子載波分配方案。該方案通過採用更新遠慢於無線信道波動的資源分配策略，從而使計算複雜度和控制信令大大降低。本文根據不同的應用背景，將慢適應子載波分配問題描述成為幾個不同的隨機規劃問題。其中，我們設計了一個高效的算法專門用以求解機會約束規劃類型的子載波分配問題。 / 在MIMO天線系統中，本文提出了一套天線和發射功率聯合分配的方案，使利用多天線支持單一移動終端上的多個無線電模塊同時運行成為可能。該方案最大化了長期系統吞吐量，同時以容許偶爾違反系統約束的方式滿足每個無線模塊的短期傳輸速率需求。結果表明，最優天線和發射功率分配顯著提高系統的吞吐量和滿足QoS的成功概率；而最優天線分配與最優功率分配相比，對提高系統吞吐量有更大的貢獻。 / 在位置感知網絡中，本文提出了一套魯棒功率分配方案，用以抵抗網絡參數的不確定性，這些參數包括用戶位置以及信道狀態。本文提出了一種新的魯棒優化方法，用以獲得最優功率分配，從而提高定位精度和網絡能效。結果表明，魯棒方案顯著優於非魯棒的功率分配和平均分配方案。 / 本論文著眼於縮短傳統基於靜態優化的設計與其現實針對性之間的差距。鑒於許多無線系統的參數在本質上都具有隨機性，本文所提出的採用隨機優化的資源分配方法，有望在未來無線通信中得到更多的應用。 / The growing demand of ubiquitous wireless services has prompted the efficient utilization of scarce radio resources. Over the years, optimization techniques have been widely employed to design optimal resource allocation schemes to achieve performance improvement. Most work in this area assumes that the system parameters defining the optimization problem are precisely known. In practical systems, however, these parameters are often time varying and random. Ignoring the parameter uncertainties would easily lead to suboptimality or even infeasible solutions that violate system operation constraints. / This thesis presents a stochastic optimization framework for the dynamic resource allocation in wireless communications. In particular, practice-relevant problem formulations are proposed to capture the stochastic nature of the uncertain system parameters, and efficient algorithms are developed to obtain the optimal allocation decisions. The proposed framework has been successfully applied in three promising wireless systems: adaptive orthogonal frequency division multiple access (OFDMA) systems, multiple-input and multiple-output (MIMO) antenna systems, and location-aware networks. Each application contains practice-relevant challenges, where the conventional designs using deterministic optimization fail to provide satisfactory quality of service (QoS). The results demonstrate that the dynamic resource allocation using stochastic optimization achieves more robust QoS performance and remarkably enhances the system practicality. / In adaptive OFDMA systems, a slow adaptation scheme is proposed for optimal subcarrier allocation. The proposed scheme updates the resource allocation decisions on a much slower timescale than that of channel fluctuation, which drastically reduces the computational complexity and control signaling overhead. The problems are formulated into several stochastic programs based on different application scenarios. An efficient algorithm is developed for solving the chance constrained subcarrier allocation problem. / In MIMO antenna systems, an antenna-and-power allocation scheme is proposed to enable the use of multiple antennas to support multiple radios co-operating on the same mobile device. The proposed scheme maximizes the long-term system throughput while satisfying the short-term data rate requirement of each radio transmission with occasional outage. The results show that both system throughput and success probability of QoS satisfaction are improved, and the optimal antenna allocation contributes to a larger portion of throughput increase comparing with the optimal power allocation. / In location-aware networks, robust power allocation schemes are proposed to combat the uncertainties in network parameters including user positions and channel conditions. A novel robust optimization method is developed to obtain the optimal power allocation, which improves both localization accuracy and network energy efficiency. The results show that the robust schemes remarkably outperform both non-robust power allocation and uniform allocation. / The goal of this thesis is to bridge the gap between the current designs under the deterministic optimization framework and their practical relevance. Given the fact that many wireless system parameters are stochastic in nature, the proposed resource allocation methods using stochastic optimization are expected to find further applications in wireless communications. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Li, Weiliang. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 157-175). / Electronic reproduction.

Orientador: Maria Eugênia Porém / Banca: Raquel Cabral / Banca: Pedro Jaime de Coelho Júnior / Resumo: As relações sobre comunicação, diversidade e gestão nas organizações costumam ser estabelecidas com foco na mensuração de desempenho, na busca por resultados econômicos e no uso de modelos, ferramentas e discursos que, ao invés de dialogar com questões sociais, históricas e de direito a partir do que é genuinamente humano, podem contribuir com ações discriminatórias ou microagressivas. Diante desse cenário, este trabalho parte do pressuposto de que em uma organização a comunicação deve protagonizar processos para a inclusão da diversidade, na medida em que produz a circulação de significados compartilhados, intervém na realidade e constrói um novo sentido de atuação, e que a ótica de gestores(as) organizacionais sobre a comunicação organizacional pode impactar efetivamente nas políticas e ações de diversidade nas empresas. Por essa perspectiva, constitui-se como objetivo da pesquisa analisar em que medida gestores e gestoras compreendem a comunicação organizacional como protagonista de processos inclusivos da diversidade e qual a importância do papel das pessoas que estão em cargos de gestão nesta articulação, discutindo a comunicação organizacional como um encontro que reconhece a alteridade e a diversidade, e entendendo o papel da gestão no processo comunicação para a coabitação organizacional, que presume participação, democracia, respeito, valores compartilhados, solidariedade e parcerias sustentáveis. A metodologia adotada compreende uma fase de levantamento bibliográfic...

Considering this, this research assumes that communication must be prioritized to achieve diversity and inclusion in a company, as it creates shared meanings, interfers in the reality, and creates a new way of acting. In addition, organizational managers‟ perspectives about the organizational communication can effectively influence the policies and procedures of many companies. According to this perspective, the aim of this research is to analyse how managers view organizational communication as the priority of diversity and inclusion processes and the importance of managers‟ role in this process, discussing about the organizational communication as a strategy that recognizes alterity and diversity, and understanding the role of management in the process of communication to reach the organizational cohabitation, which presumes participation, democracy, respect, shared values, solidarity, and durable partnerships. The methodoly adopted involved a bibliographic search and an empirical research carried out with two companies from the cities of Bauru and Marilia, which were elected as one of the 150 best companies to work at by the m...

This thesis presents a method for managing periods of communication loss between multiple spacecraft in formation flying (MSFF), and analyzes the effects of this method on the stability of the formation keeping control algorithm. The controller of interest in this work in an adaptive nonlinear controller, where synchronization is also incorporated to force the position tracking errors to converge to zero at the same rate. The communication loss compensation technique proposed in this thesis is to use the previously communicated data in lieu of the lost data, which is an effective and computationally-efficient technique that is advantageous for small satellites. The performance parameter of interest in this research is the maximum rate of communication loss that an MSFF system can withstand before going unstable, and this is analyzed theoretically and through simulations. Finally, experiments involving multiple robots in formation with communication loss are conducted, and the results are presented.
