131	An investigation of seasonal disturbance intensity on wetland grass belts of Nysvley Nature Reserve Gelebe, Vhuhwavho 17 May 2019 (has links) MSc (Botany) / Department of Botany / The use of disturbance in the management of Savanna is a common rangeland practice in South Africa. A two-season trial was established in June 2016 and December 2016 to evaluate the effects of disturbance of different intensities on wetland belts in the Nylsvley Nature Reserve. The disturbances were in three different belts of different grass types at different intensities. The experimental treatments consisted of two different intensities, namely; high (H) and low (L). The Cyperus amabilis belt was regarded as site 1, the Sporobolus africanus as site 2, and the Themeda triandra as site 3. Seventeen kites were contracted in each belt, two times 1 m × 1 m at high and low intensity, followed by two times 2 m × 2 m one at high intensity. The results showed that disturbance affects the topsoil by removing the soil which is rich in nutrients producing pioneer species for the first few months and then original species were seen inhibiting again. / NRF Disturbance Low intensity High intensity Wetland belt Waterlogged Clay soil Cyperue amabilis Cynodon dactylon Setaria sphaceleta Themenda triandra Sporobolus africanus 577.6840968257 Wetlands -- South Africa -- Limpopo

The Marriage Moments program consists of a guidebook and a video that were designed to strengthen marriages during the transition to parenthood and is used in the context of a home visitation program for first-time parents. Participants in the study included 119 married couples who had recently given birth to their first child. They were assigned to either a treatment, comparison or control group. The treatment group received the Marriage Moments curriculum as well as the Welcome Baby home visitation curriculum, the comparison group only received the Welcome Baby curriculum and the control group received neither program. Data were gathered through a battery of self- and spouse-report measures given at 3-months, 4-months, and 9-months postpartum. Relationship outcome measures included in this study were the Marital Virtues Profile, Revised-Dyadic Adjustment Scale, RELATE Satisfaction subscale, Transition Adjustment Scale, Father Involvement Scale, Household Labor Scale, and Maternal Depression Scale. Despite positive evaluations of the program from participants, analyses revealed a lack of significant, positive effects for members of the treatment group. Further research is needed before reliable conclusions can be drawn about the value of a marital virtues model as a guide for low intensity intervention.

133	Alternative Pathways to Peace and Development in Rural Chiapas, Mexico Hollinger, Keith H. 01 July 2011 (has links) The concept of peacebuilding holds enormous importance for international relations, particularly in regions facing impending violent conflict and those recovering from such conflict. However, in order for peacebuilding to be a viable alternative to traditional peace operations, scholars and practitioners need to have a shared understanding of what peacebuilding is and what goals it hopes to achieve, in addition to fluid strategies for implementation. This dissertation seeks to identify strategies for building sustainable peace through sustainable community development and democratization. Using a qualitative metasynthesis of five ethnographies conducted in Chiapas Mexico, this dissertation develops mid-range theories, or strategies, for building peace in Chiapas and in regions experiencing low-intensity conflict more generally. These strategies are based upon the development of Pluriethnic collective governance at the local level in regions that are experiencing low-intensity conflict related to indigenous communities. / Ph.

134	Low Intensity Conflict: Contemporary Approaches and Strategic Thinking Searle, Deane January 2007 (has links) Low Intensity Conflict (LIC) is a significant feature of the contemporary world and it is a particular challenge to the armed forces of many states which are involved is such conflict, or are likely to become so. This thesis is not concerned with how such difficult conflict situations arise. Rather it is concerned with how, from the point of view of the state, they may be contained and ultimately brought to a satisfactory resolution. The work is thus concerned with the practicalities of ending LIC. More specifically, the purpose of this research is to establish a framework of doctrinal and military principles applicable to the prevention and resolution of LIC. The principles of this thesis are based in numerous historical examples of LIC and six in depth case studies. These distilled principles are analysed in two central chapters, and are then applied in two latter defence force chapters so as to ensure there practicality and resilience. Numerous defence academics and military practitioners have been consulted in the production of this thesis; their contribution has further reinforced the functionality of the principles examined in this research. The research illustrates the criticality of a holistic approach to LIC. The function of this approach is to guarantee the stability of the sovereign state, by unifying civil, police, intelligence and military services. The effectiveness of the military elements must also be ensured, as military force is central to the suppression of LIC. Consequently, the research makes strategic and operational prescriptions, so as to improve the capability of defence forces that are concerned with preventing or resolving LIC. low intensity conflict counterinsurgent counterinsurgency insurgent insurgency guerrilla small wars conflict combat urban conflict new zealand defence force australian defence force afghanistan iraq somalia chechnya east timor bougainville bosnia defence policy doctrine soviet russia red army airpower combined arms intelligence command control communications surveillance intervention peacekeeping peacebuilding peace enforcement strategy tactics infantry armour aviation non-urban terrain psychological war small scale operations combat service support civil military affairs urban dominance rapid dominance manoeuvre warfare nationalism restraint civil resolve operation enduring freedom operation anaconda suppressing fire joint warfare synergy strike target acquisition civil affairs public affairs operation iraqi freedom operation telic professionalism asymmetric warfare power projection sea power precision strike C4ISTAR C4ISR HUMINT logistics coalition post war environment internal security population security civil support unitary command expeditionary civil service personnel techniques standard operating procedures artillery protection manoeuvrability firepower visibility helicopters aircraft friendly fire initiative policy training light armoured vehicle light operational vehicle aviation navy air force army counter communications sea control maritime power projection rules of engagement engineers
