Africa's foreign policy and political borders : Nigeria and her neighbours

Uchehara, K. January 2004 (has links)
International boundaries inherited from colonialism have given room to territorial disputes and the existing boundary conflicts in the West African Region, and are an endemic feature of Nigeria's relations with her immediate neighbours. The thesis examines the 18 border disputes that Nigeria has been involved in since independence. The thesis begins by setting the scene in terms understanding Nigeria's foreign policy principles and objectives since independence and, in particular, its policy towards border disputes across the continent of Africa such as the Congo/Katanga, Uganda/Tanzania, Ethiopia/Somalia and Morocco/Algeria (chapter 2). The thesis then moves on to consider the underlying problems that have faced Nigeria as regards its borders as a result of colonisation (chapter 3). As the history is traced of the stages in the definition of Nigeria's boundaries, it becomes apparent that many border issues were unresolved or that decisions were made that were likely to be contested in the future. In chapter 4 the thesis turns to a detailed examination of the border disputes that have arisen in the last 43 years of independence between Nigeria and her close neighbours, Benin, Chad, Equatorial Guinea, Cameroon and Niger. Chapter 5 analyses the data provided. It finds that the way the dispute was handled was closely related to the regime type. Under the liberal democratic regimes of Balewa, Shagari, Obasanjo II, disputes were largely dealt with by diplomacy and negotiation. Whereas under the autocratic regimes of military leaders such as Generals Ironsi, Gowen, Muhammed, Obasanjo, Buhari, Babangida, Abacha's and Abubaker's the disputes brought a response of a threat of force or aggressive use of force. It concludes that liberal democracy profoundly affects how border disputes are handled and is a force for peace and stability.

Economic Performance and Social Conflicts in Chinese History

Liu, Cong January 2016 (has links)
This thesis consists of four chapters on economic performance and social conflicts in Chinese history. The first chapter examines the impact of a major tax reform on protests in the eighteenth century in China. The de jure effect of this reform was to increase the tax burden on the gentry and decrease the tax burden on commoners, yet the de facto effect is under debate. I combine multiple databases into an annual panel dataset from 1700 to 1750 and use detailed information on protest to identify income shocks and tax incidence. The regression results after controlling for provincial fixed effects and national shocks show that the tax reform increased local protests by 0.3 incidents per year, which equals to half a standard deviation before the reform started. Further examination suggests that the de facto effects of the reform hurt commoners rather than the gentry. First, it increased protests by commoners but had no effects on protests by the gentry. Second, provinces with more gentry landlords also had larger increases in the frequency of protests. These results support that the gentry managed to pass the increased tax burdens on to the commoners. This analysis provides quantitative evidence that links social standing and tax burdens in pre-modern society. The second chapter studies the effect of income shocks on different types of conflicts. I consider two types of conflicts: protests, such as grain crises, that requested actions by the government, and revolutionary activities that aimed to overthrow the central government. From 1902 to 1911, China experienced both types of conflicts. I use a detailed record of local conflicts to identify the causes and leaders of each conflict. Combining this information with exogenous price shocks from the international agricultural market, I find that negative income shocks coming from drops in the export price of tea and the increases in the import price of cotton tended to increase the overall frequency of conflicts in general and protests that requested actions from the government. However, the same negative income shocks sometimes reduced revolutionary activities, which was probably caused by the shortage of resources in organizing these activities. These finding suggest an ``income effect'' on conflicts, probably due to the resources needed to organize the activities. The third chapter examines the impact of civil wars on the local economy using newly documented information about civil wars across regions in early-twentieth century China. During this period, China was de facto divided into several regions. Each region was controlled by different warlords or political groups. Warlords fought with each other for a larger territory. I first quantitatively document the scale, timing, and location of these civil wars. Around sixty violent civil wars took place from 1911 to 1934 and 25% of the Chinese counties in my sample were involved in at least one battle. I then examine the impact of civil wars on local economic activities. I find that civil wars overall caused a small negative impact on international trade flows and a 12.1% drop in rural land values. When the results are separated into wars by political groups, the wars involving weak political groups led to 1.7% to 3.8% drop in international trade flows, while the ones by strong political groups had small positive impact on trade flows. Similarly, wars conducted by the powerful incumbent had no negative impact on land values, while the ones between the KMT and the CCP led to a 30% drop in land values. Combined with narrative evidence, the results suggest that incumbent or political groups might have protect trade or reduced harm to the local economy if they relied on tariff or land taxes to finance themselves. The fourth chapter examines the impact of World War I on the Chinese economy. The war largely increased the freight rates in international trade and decreased China's imports of manufactured products from the European countries. I combine data from multiple sources to quantify the development of China's industrial sector and changes in agricultural input prices during and after the war. The firm-level information from the textile industries shows that the textile firms expanded during the war, and the trend continued even after. Using John Buck's survey on land values and labor wages across China, I find that the growing industrial sector also raised agricultural input prices by increasing demand for raw cotton and rural laborers. However, the benefits were small and the impact was clustered around the ports.

A NEW SIMULATION-BASED CONFLICT INDICATOR AS A SURROGATE MEASURE OF SAFETY

Wang, Chen 01 January 2012 (has links)
Traffic safety is one of the most essential aspects of transportation engineering. However, most crash prediction models are statistically-based prediction methods, which require significant efforts in crash data collection and may not be applied in particular traffic environments due to the limitation of data sources. Traditional traffic conflict studies are mostly field-based studies depending on manual counting, which is also labor-intensive and oftentimes inaccurate. Nowadays, simulation tools are widely utilized in traffic conflict studies. However, there is not a surrogate indicator that is widely accepted in conflict studies. The primary objective of this research is to develop such a reliable surrogate measure for simulation-based conflict studies. An indicator named Aggregated Crash Propensity Index (ACPI) is proposed to address this void. A Probabilistic model named Crash Propensity Model (CPM) is developed to determine the crash probability of simulated conflicts by introducing probability density functions of reaction time and maximum braking rates. The CPM is able to generate the ACPI for three different conflict types: crossing, rear-end and lane change. A series of comparative and field-based analysis efforts are undertaken to evaluate the accuracy of the proposed metric. Intersections are simulated with the VISSIM micro simulation and the output is processed through SSAM to extract useful conflict data to be used as the entry into CPM model. In the comparative analysis, three studies are conducted to evaluate the safety effect of specific changes in intersection geometry and operations. The comparisons utilize the existing Highway Safety Manual (HSM) processes to determine whether ACPI can identify the same trends as those observed in the HSM. The ACPI outperforms time-to-collision-based indicators and tracks the values suggested by the HSM in terms of identifying the relative safety among various scenarios. In field-based analysis, the Spearman’s rank tests indicate that ACPI is able to identify the relative safety among traffic facilities/treatments. Moreover, ACPI-based prediction models are well fitted, suggesting its potential to be directly link to real crash. All efforts indicate that ACPI is a promising surrogate measure of safety for simulation-based studies.

Post-decision Processes : Consolidation and value conflicts in decision making

Shamoun, Sanny January 2004 (has links)
<p>The studies in the present thesis focus on post-decision processes using the theoretical framework of Differentiation and Consolidation Theory. This thesis consists of three studies. In all these studies, pre-decision evaluations are compared with post-decision evaluations in order to explore differences in evaluations of decision alternatives before and after a decision. The main aim of the studies was to describe and gain a clearer and better understanding of how people re-evaluate information, following a decision for which they have experienced the decision and outcome. The studies examine how the attractiveness evaluations of important attributes are restructured from the pre-decision to the post-decision phase; particularly restructuring processes of value conflicts. Value conflict attributes are those in which information speaks against the chosen alternative in a decision. The first study investigates an important real-life decision and illustrates different post-decision (consolidation) processes following the decision. The second study tests whether decisions with value conflicts follow the same consolidation (post-decision restructuring) processes when the conflict is controlled experimentally, as in earlier studies of less controlled real-life decisions. The third study investigates consolidation and value conflicts in decisions in which the consequences are controlled and of different magnitudes. </p><p>The studies in the present thesis have shown how attractiveness restructuring of attributes in conflict occurs in the post-decision phase. Results from the three studies indicated that attractiveness restructuring of attributes in conflict was stronger for important real-life decisions (Study 1) and in situations in which real consequences followed a decision (Study 3) than in more controlled, hypothetical decision situations (Study 2). </p><p>Finally, some proposals for future research are suggested, including studies of the effects of outcomes and consequences on consolidation of prior decisions and how a decision maker’s involvement affects his or her pre- and post-decision processes.</p>

An economic analysis of human cost in armed conflicts

Lee, Uih Ran January 2013 (has links)
This thesis seeks to analyse military and civilian loss from violence during contemporary armed conflict in order to facilitate understanding of the evolution of war and its impact on human behaviour. It comprises four chapters; the first two concentrate on the 2033 Iraq War whilst the last two are focused upon global armed conflict during the recent past. Chapter 1 explores how and to what extent military deaths during the Iraq war affect US domestic opinion, proxied by various poll questions concerning war-related issues. Having addressed irregular frequencies of poll data that restrict time series application, this chapter renders a fresh perspective on casualty-opinion research, suggesting that cumulative military casualties prior to the poll did not have an immediate effect on the poll respondents' opinion regarding the continuation of military actions in Iraq, Instead, respondents are influenced by marginal casualty information from the previous time period, implying a slow adjustment in forming opinion through the Error Correction Mechanism (ECM). Chapter 2 presents a comparative analysis to gauge any different standards between the US department of Defense and the media in counting violent civilian deaths during the Iraq war. In spite of substantial discrepancies during the initial period of the war, non-parametric tests corroborate that the US military authority and media reports had a non-differential approach towards counting violent civilian deaths during the war period across the spatial and spatiotemporal dimensions. However, the conspicuously conservative count by the US military authority during the initial stage of the war may have hindered the US forces' ability to predict and prepare for the subsequent escalation of violence that brought about large-scale human loss as well as the prolongation of the war which lasted more than 7 years. Chapter 3 analyses to what extent warring actors intentionally used lethal force against civilians, through the employment of a Civilian Targeting Index (CTI), a newly invented measure to indicate the intensity of civilian targeting for each actor. Building upon Chapter 3, Chapter 4 further examines factors that lead to warring actors targeting civilians as opposed to engaging in battle with war combatants. A dynamic panel approach shows that an increase in the degree of civilian targeting in the previous year further intensified civilian targeting in the current year for the actors involved in prolonged armed conflict.

An exploratory analysis of village search operations

Aydin, Mehmet 06 1900 (has links)
Approved for public release; distribution is unlimited / Following the cold war a new kind of threat emerged; terrorism became the most important threat used by individuals, organizations and countries to reach their goals. Turkey has suffered from terrorism for years. In Turkey, the main logistic resource for the terrorist is the villages located in remote areas. A search operation is one of the techniques used to capture the terrorists. Five village search operations scenarios are developed based on a previous study done for the New Zealand Army and the author's personal experiences. For this study, the agent-based model MANA (Map Aware Non-uniform Automata) is used. To investigate the effects of 16 variables state-of-the-art Near Orthogonal Latin Hypercube Designs are used. With a personal computer and the computational capabilities of supercomputers run by Mitre for the Marine Corps Warfighting Lab (MCWL) approximately 15000 runs are completed. In comparing the five scenarios, the significant effects on the outcome of a possible skirmish in search operations are the proficiency level of the soldiers, the employment of village guards and the support of the local people to the terrorists. The results of the analysis suggest that the most important factor affecting the Blue casualties is the initial speed and synchronization of the Blue search unit entering the village and the most important factor affecting the Red casualties is the Red Stealth. / First Lieutenant, Turkish Army

”… och alla lärare tyckte det var jättekul, men ingen ville hjälpa till.” : Pedagogers tankar om raster och mobbning. / ”…and all the teachers thought it was fun, but no one wanted to help.” : Teachers thoughts about recess and bullying.

Ekmark, Ellinor, Fares, Linda January 2016 (has links)
Syftet med denna studie är att studera pedagogers syn och åsikter kring mobbning på skolgården och hur de vill arbeta för att motverka detta; genom till exempel övervakning eller rastverksamhet. Vi ville även undersöka om pedagoger upplevde att det fanns en skillnad mellan flickor och pojkars mobbning, och om detta påverkade deras arbete på rasten. Vi har i studien använt oss av ett sociokonstruktionistiskt perspektiv. Vi valde att genomföra intervjuer på fyra skolor med totalt fjorton personer. Intervjuerna analyserades sedan för att identifiera teman som reflekterade pedagogernas tankar. Resultaten visade att många pedagoger är positiva till rastverksamhet men har främst andra idéer på hur mobbning skall bekämpas på skolgården. Många pedagoger såg skillnader mellan flickor och pojkars mobbning, vilket stämde väl överens med tidigare forskning. För att motverka skillnader ville pedagogerna gärna blanda flickor och pojkar mer i lek. När det kom till pedagogers roll på skolgården visade det sig att många pedagoger ogillade titeln rastvakt, samtidigt som de sa emot sig kring denna roll då de efterlyste mer övervakning på skolgården.

Why has the Arab League failed as a regional security organisation? : an analysis of the Arab League's conditions of emergence, characteristics and the internal and external challenges that defined and redefined its regional security role

Abusidu-Al-Ghoul, Fady Y. January 2012 (has links)
This study presents a detailed examination of the Arab League's history, development, structure and roles in an effort to understand the cause of its failure as a regional security organisation. The research's point of departure is a questioning of the nature and scope of this failure in terms of the interplay between the conditions under which it was formed and the many actors and dynamics that had a long term-impact on the prospects for the League. To this end, the study looks at the League's conditions of emergence and Arab-Arab relations with the focus on Arab national security as the main concept determining its security role. The research synthesises methods of analysis from the existing literature and schools of thought so as to identify where and why failure and success occurred in relation to international relations theories, the security and international organisations literature, and comparable international models. The development and conditions affecting the League as discussed in the research demonstrate that none of the existing broad theories or approaches can fully explain the League's failure; however, the constructivist approach, although never before applied in this context, is shown to offer the most relevant approach for explaining this organisation and its unique parameters. The research also examines the role played by the Arab League in regional peacekeeping and conflict prevention in the context of Arab national security, with Palestine as a case study.

Professional Commitment, Organizational Commitment, and Organizational-Professional Conflict in the Internal Audit Function Model: Development and Test

Quarles, Ross 05 1900 (has links)
This dissertation is a descriptive, exploratory examination of professional commitment, organizational commitment, and conflict between those commitments in the internal audit profession. That conflict has been suggested in prior studies as the source of dysfunctional outcomes such as increased role stress, high turnover, decreased job satisfaction, and the exercise of improper judgment leading to audit failures. The descriptive aspect of this study deals with the development of a more comprehensive structural model of the factors and relationships involved in commitment and conflict than has been developed by previous research dealing with accountants. The exploratory aspect deals with the testing and refinement of the developed model utilizing the internal audit profession as the field of examination. The model developed in this study is derived from the synthesis of factors suggested by role theory, the concept of side bets, the cosmopolitan-local construct, and the concept of commitment as a process. This research utilizes a questionnaire administered to 205 practicing internal auditors in order to test 30 hypothesized relationships. Path analysis is used to determine the significant direct relationships between variables with a process of theory trimming being conducted in order to produce more parsimonious structural models. Indirect relationships between significant variables are identified and their redundant or suppressive nature determined. Explanations of these suppressive or redundant relationships are provided based on the theoretical considerations identified above. Such a determination and explanation of the redundant and suppressive indirect relationships involved in the commitment-conflict relationship has not been accomplished in earlier studies of the subject. Although the procedures used here do not support causal conclusions, the findings of this study indirectly provide evidence that conflict between the two commitments in the internal audit area is not to be considered inherent. The findings also suggest a possible undesirable relationship between organizational formalization and professional commitment.
