The Task-Based Approach： Noticing and Attention Management Tasks to Enhance Written Production

The paper reports the results of a field study which was carried out at the Language Centre of the University of Naples and originated in the observation that learning the Italian language was not perceived by ab initio students as connected to their personal and academic experiences. The claim of this research is that a procedural syllabus based on texts and tasks facilitates both the acquisition of Italian as a foreign language and the integration of language and content. Each text proposed to the learners was accompanied and enhanced by pre-, while-, and production-tasks. A particular emphasis was assigned to noticing and attention management tasks in the pre and while phase Production tasks in a later phase favoured interlanguage development by combining representational structures with controlled attention. The method of the study was a combination of qualitative and quantitative approach at any stage. Measures for written production during the course and to assess final exams were： Holistic Rating （fluency and creativity）, Accuracy Ratios （intelligibility index and error index）, and Complexity Ratios （dependent and coordinate clauses per t-units ratio and re-elaboration of a model or text type）. At the final exams, Texts and tasks learners outperformed non-texts and tasks learners. In conclusion, an input related to personal and/or academic interests, to be processed through tasks, allowed learners a rapid interlanguage change and development

Coordinated dynamic mission planning scheme for intelligent multi-agent systems

Mission planning was thoroughly studied in the areas of multiple intelligent agent systems,such as multiple unmanned air vehicles,and multiple processor systems.However,it still faces challenges due to the system complexity,the execution order constraints,and the dynamic environment uncertainty.To address it,a coordinated dynamic mission planning scheme is proposed utilizing the method of the weighted AND/OR tree and the AOE-Network.In the scheme,the mission is decomposed into a time-constraint weighted AND/OR tree,which is converted into an AOE-Network for mission planning.Then,a dynamic planning algorithm is designed which uses task subcontracting and dynamic re-decomposition to coordinate conflicts.The scheme can reduce the task complexity and its execution time by implementing real-time dynamic re-planning.The simulation proves the effectiveness of this approach.

Resilient Development of Urban Waterfront in Fast-Changing Cities--A Case Study of Wuhan, China

Urban waterfronts, where the land of city meets a body of water, are unique and finite resources representing the best opportunities for community enhancement and enrichment. On the other hand, waterfronts are also high-risk areas, where the water-related disasters could seriously affect the long-term sustainability of urban environment. This paper focuses on the relationship of the cities with their waterfronts. It presents a case study of Wuhan--a Chinese metropolis, where waterfronts play an important role in its urban planning policy. It attempts to investigate the mechanism of waterfront transformation, and to find out which strategies to adapt and what resilience means in terms of urban waterfronts in a rapidly transforming city. This article examines some representative urban projects on the waterfront and summarizes spatial models applied on the waterfront with distinct policies. Finally, it demonstrates that an urban waterfront is an ＂osmotic interface＂ which should be more correctly envisaged as a network of places, functions, additions and hinges between the city and its water environment. It clarifies that waterfront areas represent a multidisciplinary and multitasking issue in perspective of urban resilient development.

The Value of Saudi Arabia Industrial Firms Between the Modigliani-Miller＇s and Gordon＇s Models： An Empirical Study on Cement Companies in Saudi Arabia

The most important target of the financial management is to develop the values of the foundation and develop the wealth of shareholders （wealth of the owners）, which is the primary target of the qualified and successful financial management. This target, developing the value of the foundation, depends on the total profit that could be achieved by the company and counting the profit per share, but undoubtedly, the financial management should consider the other targets such as social responsibility and exchange between risk and revenue and others. This research, with its both theoretical and practical aspects, aims at illuminating the value of some foundations in Saudi Arabia, which are already registered in the stock market, by comparing the value of each foundation using two models namely the model of Modigliani-Miller （M＆M） and the model of Gordon. In spite of the difficulties found in the usage of both models, especially Gordon＇s model, we will use both of them to explain the aspects of imperfection in each model. This research will depend on a sample of Sandi industrial companies by getting financial data of these companies over a past decade and the usage of these data, in other words, to measure the value of Saudi companies against the market.

Attention Strategy Training Affecting Second Language Vocabulary Acquisition of College Students

This paper analyzes attention theory in the cognitive psychology and introduces second language vocabulary acquisition. The filter theory and attention resource theory in the attention theory points out that attention has a key effect on the learner＇s cognitive vocabulary learning by raising students＇ expectations for new words, by increasing the frequency of exposure to them, by enhancing their perceptual salience, and by increasing the task demand for word study. The fact proves that enhancing attention in input could promote students＇ vocabulary acquisition and help them form efficient vocabulary learning strategy suitable for their levels of proficiency.

Accounting for goodwill under FRS 136： Case of Malaysian plantation companies

The introduction of FRS （financial reporting standards） 136 to Malaysian PLC＇s （public limited company） in 2006 indirectly formalized accounting for purchased goodwill for the first time. Based on a sample of 2006 annual reports of 10 Main Board companies from plantation sector, the study finds the level of desired disclosure has yet to be met. Whilst the intention of the standard is noble, actual practice for first time reporting entities indicate that Malaysian PLC＇s and their auditors have far to go before they can meet the expectation set by FRS 136 in particular and International Financial Reporting Standards in general.

An incremental ant colony optimization based approach to task assignment to processors for multiprocessor scheduling

Optimized task scheduling is one of the most important challenges to achieve high performance in multiprocessor environments such as parallel and distributed systems. Most introduced task-scheduling algorithms are based on the so-called list scheduling technique. The basic idea behind list scheduling is to prepare a sequence of nodes in the form of a list for scheduling by assigning them some priority measurements, and then repeatedly removing the node with the highest priority from the list and allocating it to the processor providing the earliest start time （EST）. Therefore, it can be inferred that the makespans obtained are dominated by two major factors： （1） which order of tasks should be selected （sequence subproblem）; （2） how the selected order should be assigned to the processors （assignment subproblem）. A number of good approaches for overcoming the task sequence dilemma have been proposed in the literature, while the task assignment problem has not been studied much. The results of this study prove that assigning tasks to the processors using the traditional EST method is not optimum; in addition, a novel approach based on the ant colony optimization algorithm is introduced, which can find far better solutions.
