Prominent legal cases of the 1980s and 1990s sparked lengthy debates and important research questions surrounding the fallibility and general reliability of memory. But what lessons have we learned, some 35 years later, about the role of memory in the judicial system? In this review, we focus on what we now know about the consequences of the fallibility of memory for legal proceedings. We present a brief historical overview of false memories that focuses on three critical forensic areas that changed memory research: children as eyewitnesses, historic sexual abuse and eyewitness (mis)identification. We revisit some of the prominent trials of the 1980s and 1990s to not only consider the role false memories have played in judicial decisions, but also to see how this has helped us understand memory today. Finally, we cons...

The types of equipment used and the environmental conditions will affect the man- and machine-hours required to complete a given amount of work. Earth moving tools and equipment catalogue is essential for estimating onsite productivity and measuring project performance in earthmoving operations. This paper presents an online catalogue for earth moving operations Short Message Service (SMS), based system, developed for estimating performance of earth moving operations which will greatly assist contractors in selecting tools and equipment for earth works using SMS, making the system economical and efficient. The proposed system is programmed in C# programming language. The database is hosted on a MySQL and it uses Global system for mobile communication (GSM) to connect to a modem which in turn sends and recei...

Mineral exploitation contributes to economic growth and development in most world economies. Kenya ranks third largest producer of soda ash and seventh producer of fluorspar in the world. Export statistics indicate a constantly growing sector making mining as the next economic frontier. The sector consists artisanal and large-scale mining, each with varying environmental impacts. This study provides exposure on the environmental impacts of mining activities and its mitigation measures; it focused on the mining activities in Mkuki ranch. Primary and secondary data was collected, analysed, findings and recommendations documented, changing the narrative in managing environmental impacts in mining areas.

Retention of acceptable serviceability and performance of asphalt concrete roads during the design life is highly dependent on long term monitoring of the road surface condition, and implementing the right decision to start the maintenance, and the right maintenance alternative at the right time. Asphalt Concrete Road is a multi-layer system that distributes the vehicular and pedestrian loads over a larger area. It helps to make them durable and able to withstand traffic and the environment. Pavement consists of three basic layers the first layer is Sub grade (Gravel) which is the foundation layer, the second layer is sub base (layer Assistant foundation) and the top layer is base (a layer of pavement) which consists of Bituminous Carpet + Bituminous Macadam. Roads are high-cost investments and need constant maintenance so that these investments continue to perform as required. Therefore, care must be taken to maintain the roads in optimum maintenance and in a scientific manner. This research paper describes assessment of Asphalt Concrete Roads (ACR) distresses; their causes and possible engineering solution to improve on its management. Visual inspection and walk through techniques for evaluating Asphalt Concrete roads surface condition along the 28Km stretch Voi to Maungu, questionnaires and interviews will be utilised to achieve this. The findings of this research will be very instrumental as it will be key in Distress Management (DM), as it provides data showing most to least distresses in asphalt concrete roads, their causes, and possible engineering solution more so distresses intensity and severity will be identified hence present condition rating index (PCRI) of the road surface determined.

There are many factors that impede on successful completion of projects on time, budget, and quality. This study sought to investigate on the factors that significantly contributed to time and cost overruns on construction projects in Kenya, evaluate their relative ranking; and to quantify their impacts. The study was based on a questionnaire survey among persons drawn from contractors, consultants and other stakeholders in the construction industry. Significant variables from the survey, revealed various underlying factors example; Inaccurate estimates of project financing division between design and construction teams, contractor inabilities, improper project preparation, poor resource planning, and interpretation of requirements, works definition, timeliness, government bureaucracy, and risk allocation as having been significant contributors to time and cost overruns. These variables and underlying factors have potential of recurring in future projects, there is need to anticipate their occurrence, and to continually design appropriate strategies and mechanisms to overcome or minimize their potential impacts. Recommendations are given to assist the construction sector and other construction stakeholders on how effective project management could be done on future projects planning and implementation. Projects owners, managers and agencies in developing their project management strategies, can use the findings of this project as a reference.

The types of equipment used and the environmental conditions will affect the man and machine-hours required to complete a given amount of work. This paper presents a management model using Geospatial Techniques (GT) for managing earth moving operations (EMO).
The developed model using Geospatial techniques comprises of Geographical Information System (GIS) and Geographical Positioning system (GPS), based model, and developed for managing earth moving operations. The proposed system is programmed in PHP programming language. The database is hosted on a MYSQL and it uses Global system for mobile communication (GSM) to connect to a modem that in turn sends and receive short messages (SMS) to and from a system administrator who in turn evaluates the operations performance.
The developed model has been coded and the code request must contain only alphanumeric characters. Real case example of GT developed model is analyzed to demonstrate its features and how it works. When applied in the earthmoving industry the system can be an enviable asset to earth moving operators in increasing efficiency in managing earthmoving operations.
