Key Concepts: Sensory modulation dysfunction, sensory processing disorder, high threshold, low
threshold, sensory profile, low registration behaviour, sensory seeking behaviour,
sensory sensitive behaviour, sensation avoiding behaviour.
In order to treat a child with sensory modulation disorder (SMD), the impact of SMD on the child’s
occupational sphere should be taken into account. This includes the effect of SMD in the parent on
the child’s development and behaviour. This study determined the probability of agreement between
the parent and child’s sensory profiles.
A quantitative, cross sectional study design established the sensory profiles of 81 children and their
parents. Results indicated a moderate probability that a child with SMD may have a parent with
SMD. A moderate to high probability existed for a parent with SMD to have a child with SMD. This
supports the supposition that there is a hereditary component to SMD, with learned sedentary
behavioural patterns.
The treatment implications include considering the parent’s reaction to their own sensory thresholds
and the influence this has on the child’s treatment and learnt behaviour
ECONOMIC CONTRIBUTIONS OF TOURISM EVENTS: A MIXED-METHODS ANALYSIS OF TOMOHON INTERNATIONAL FLOWER FESTIVAL IMPACT ON LOCAL ECONOMY
No full textTourism festivals are being utilized to develop local economies in developing countries, but it remains unclear whether they are effective. We conducted several pieces of research to gain a deeper understanding of this. We examined the Tomohon International Flower Festival (TIFF) and its economic impact in Tomohon. We engaged with 312 residents, business owners and tourists through the festival. For further detailed information, we conducted face-to-face interviews with 24 respondents. The study reveals that TIFF was highly beneficial to the economy. On average, the businesses made 67.4% more money, and the locals made 34.7% more. Temporary employment was approximately 1,847, and residents filled 78.9 percent of them. The average rental equilibrium in the city center was 2.8 times higher than at the outskirts (Gini coefficient = 0.487). We identified three significant factors which contribute to the degree to which the festival will generate economic benefits: the siting of the event facilities relative to the festival location, the compatibility of the festival with the local business sector and the quality of the local businesses. This paper demonstrates that tourism events can deliver numerous benefits; however, these are unevenly distributed and can exacerbate existing inequalities between regions and sectors. The results suggest that planners should design festivals to ensure that the benefits of the festivals are distributed to all members of the community. The policy demonstrates how to invite everyone to the festival simultaneously, upgrade facilities in a remote location, and provide more growth opportunities, which is essential for contributing more to the local economy
The moving and settling of plastic in the ocean: Forward and reverse time modelling of plastic particles
No full textThe growing amount of plastic pollution in the oceans is worldwide a huge problem. There is an increasing amount of projects that try to clean up this pollution. To remove the pollution efficiently, it is useful to know how plastic litter moves, degrades and sinks. Models are being developed that can describe what happens with plastic in the ocean. To model the behaviour of plastic in the ocean a lot of parameters need to be taken into account. The transport of plastic particles is largely determined by processes like the wind and the current but their movement also has a random character due to dispersion. Due to this random movement, the future position of a particle can be described by a probability distribution. To find that probability distribution, the Kolmogorov forward equation (or Fokker-Planck equation), in this context the same as the advection-diffusion equation, needs to be solved.It is also possible that the plastic particles sink and settle on the bottom of the ocean. One goal of this project was to incorporate the settling of particles as an extra term into the advection-diffusion equation. Forward models are used to predict where particles will go to. It can also be useful to have reverse time models that can describe where particles had their origin. To make reverse time models, it is necessary to solve a reverse time advection-diffusion equation. The main goal of this project was to derive and solve the reverse time advection-diffusion equation that includes the settling of particles. This is done by finding the adjoint of the Kolmogorov forward equation and the settling term.Applied Mathematics | Applied Physic
Modelling the lateral flow and sediment dynamics in estuaries
No full textEstuaries have always been important for mankind and therefore it is essential to have a good understanding of the flow and sediment dynamics there. The goal of this thesis is twofold. One objective is to use an existing model to gain a more thorough understanding of the flow dynamics in an estuary. The second objective is to extend the model such that it can also compute the suspended sediment concentration in a cross-section. The equations governing the flow dynamics are the shallow water equations. The advection-diffusion equation governs the sediment dynamics. To compute the flow and suspended sediment concentration in a cross-section, conditions are assumed to be uniform in the along-channel direction. To solve the equations a coordinate transformation is applied first. After the transformation, the cross-section of the channel is represented in the computational domain by a rectangle. In the vertical direction, an eigenfunction expansion is used with eigenfunctions derived from a special case of the Sturm-Liouville eigenvalue problem. In the horizontal direction, derivatives are approximated with a central finite difference scheme. In the frequency domain, variables are expressed as the sum of tidal components. The Galerkin method is applied in both the vertical direction and the frequency domain to optimise the weight functions for every location along the transect. The system obtained with the Galerkin method is solved using Newton-Raphson iterations and an LU-decomposition. To find the distribution of the erosion coefficient corresponding to a morphodynamic equilibrium, a time integration method is used. The effect of several parameters on the advective contribution to the cross-channel flow is systematically investigated. The results show that the steepness of the bottom slope affects the magnitude of the advective contribution to the residual lateral flow. For a steep bottom slope the contribution is large and for a gradual bottom slope the contribution is small. The curvature of the channel strongly affects the total cross-channel flow, depending on the magnitude of the radius of curvature, but hardly affects the flow caused by advection. The lateral density gradient can largely affect the \mbox{cross-channel} flow. Especially, the amplitude of the M tidal component of the density gradient affects the advective contribution to the flow. Both the magnitude and characteristics of the advective contribution change when the amplitude of the M tidal component of the density gradient is varied. The phase of the M tidal component of the density gradient hardly affects the cross-channel flow and advective contribution of the flow. Measurement data of a cross-section of the Ems is compared with a simulation of this situation. The magnitude of the lateral flow is similar for the measurements and model results but there is a difference in the direction of the flow in the upper part of the water column. This deviation could be caused by the description of the free surface. In the measurements there is a time-varying thickness of the water column whereas the rigid lid assumption is applied in the model. However, other differences between the simulation and the actual situation could have contributed to a deviation between the measurements and model results as well. The results for the sediment module show that the model works as expected for a prescribed erosion coefficient and for computing the erosion coefficient in morphodynamic equilibrium for situations with only diffusive transport. For simple situations the analytical solution is approximated and for more complicated situations the results agree with the physical intuition. The main recommendation for further research is to investigate how the model can be extended such that it is also possible to compute the erosion coefficient in morphodynamic equilibrium for situations with both advective and diffusive sediment transport.Applied Mathematics | Computational Science and Engineerin

Strome lewende water : 'n interpretasie van Johannes 7:37-39 met verwysing na die huttefees, vir die konteks van wit Suid-Afrikaners in die 21e eeu
No full textThesis (MPhil (Ancient Studies. Centre for Bible Interpretation and Translation in Africa))--Stellenbosch University, 2006.This thesis explores the invitation and promise extended by Jesus in John 7:37-39 from the Jewish perspective against the background of the water libation ceremony that takes place during the Feast of Tabernacles, with the aim of offering an enriched interpretation of the text for Christian believers. Traditionally the words of Jesus in verses 37 and 38 are interpreted according to verse 39 as a reference to the pouring out of the Holy Spirit after Jesus has been glorified. Such an interpretation does not take into account the Jewish background against which the text is set.
The work gives a broad overview of the unique contents and message of the Gospel of John. The genre of the gospel is discussed, the author and the origin of the work are considered, as are the world of the author and the first readers, the composition of the text, the language and language usage and the purpose of the work.
A consideration of the interpretations of John 7:37-39 given by other commentators is offered in detail. Questions resulting from the text are discussed, such as which day is meant by the phrase “the last and greatest day of the feast” in verse 37, and, who is meant to be the source of the living water promised by Jesus in verse 38: Jesus himself or the believer.
The historical background of the Feast of Tabernacles is explored. The institution of the feast as a harvest festival as well as the connection of the feast with the exodus from Egypt and the re-institution of the Law after the Exile are considered. The elements of the feast as expressed in the text of the Old Testament are discussed and references to the feast in the texts of the Old and New Testaments are supplied.
The symbolism of water in the Old and New Testament is studied. Water is used as a symbolic expression of God’s power in the creation narrative and in God’s presence in nature. In the Old Testament water is also used as evidence of God’s blessing but when water is withheld it is seen as a symbol of God’s judgement.
My own interpretation of John 7:37-39 first considers the text as a narrative against the larger background of the Gospel of John, and second uses a socio-historical perspective of the passage with a consideration of the location of Jesus’ invitation against the backdrop of the events of the feast.
The situation of the ‘new’ South Africa after 1994 is described and the general feeling of pessimism amongst white South Africans is explored in the light of reports in the media and letters to newspaper editors. A parallel is drawn with the situation of the Jewish festival goers in John 7:37-39 to suggest that Jesus’ promise can also be applied to white South Africans to generate a positive feeling and a new identity. The conclusion is reached that the new life of blessing as promised by the text should not stop with the receivers but should flow through them to be a blessing to others.Master

Circular Economy-Based Waste Management in Tomohon City: Toward a Green Economy through Innovative and Participatory Approaches
No full textThis study aims to identify the potential for implementing a circular economy in waste management in Tomohon City as an effort to support the transition toward a green economy. A descriptive qualitative approach was employed, using field observation, in-depth interviews with environmental and economic actors, and policy document analysis. The research was conducted in strategic locations such as the Final Disposal Site (TPA), traditional markets, waste banks, and tourist destinations that serve as centers of community activity and tourism. Findings show that the current waste management system in Tomohon still follows a linear model, resulting in significant environmental pressures. However, local initiatives such as plastic recycling by MSMEs, organic composting, and active participation in waste banks provide early indications of successful circular practices. Nevertheless, scalability and integration of these models into the regional economy remain limited due to infrastructure constraints, technical capacity, and weak policy coordination. Based on these findings, recommendations include the need for investment in waste processing infrastructure, institutional strengthening of waste banks, formulation of local policies oriented toward circular economy principles, and increased community participation through education and economic incentives. With the implementation of these recommendations, Tomohon has the potential to become a model for sustainable waste management based on the circular economy in Indonesia’s mountainous urban regions
