New evidence from Southern Jordan: rethinking the role of architecture in changing societies at the beginning of the Neolithic process

The development of architecture and the settlement is central to discussions concerning the Neolithic transformation asthe very visible evidence for the changes in society that run parallel to the domestication of plants and animals. Architecture hasbeen used as an important aspect of models of how the transformation occurred, and as evidence for the sharp difference betweenhunter-gatherer and farming societies. We suggest that the emerging evidence for considerable architectural complexity from theearly Neolithic indicates that some of our interpretations depend too much on a very basic understanding of structures which arenormally seen as being primarily for residential purposes and containing households, which become the organising principle for thenew communities which are often seen as fully sedentary and described as villages. Recent work in southern Jordan suggests that inthis region at least there is little evidence for a standard house, and that structures are constructed for a range of diverse primary purposes other than simple domestic shelters.

Strategies to develop divided attention skills through video game training

Research .over the past two decades has confirmed the learning opportunities that video games can offer. The objectives of the current study were to investigate the ability of video games to enhance divided attention skills and compare these skills based on individuals' level of expertise in video game playing. Female participants aged between 17-25 years categorised as experts or novices, were divided into experimental and control groups. All participants completed the pre and post-test of divided attention between which only the experimental group received video game training. Results indicate that participants who received video game practice achieved an increase in their dual-attention skills compared to those who did not receive any training, with novices displaying a greater
enhancement in perfonnance. Implications include the provision of video game training to enhance divided attention skills in air pilot training, driving, and heavyequipment operation apart from other tasks necessitating dual-task efficiency.

A reputation-based trust model for agent societies

Trust and security issues are prevalent in agent societies, where agents are autonomously owned and operated in a networked environment. Nowadays, trust and reputation management is a promising approach to manage them. However, many reputation models su.ered from a major drawback – there is no mechanism to discourage agents from lying information when making a recommendation. Although some works do take into account of this issue, they usually do not penalize an agent for making poor referrals. Worse, some systems actually judge an agents referral reputation based on its service reputation. In situations where this is unacceptable, we need to have a mechanism where agents are not only discouraged from making poor referrals, but are also penalized when doing so. Towards this, we propose a reputation-based trust model that considers an agents referral reputation as a separate entity within the broader sense of an agents reputation. Our objective is not to replace any existing reputation mechanisms, but rather to complement and extend them.

Identity in multicultural societies: who do we think we are?

This paper examines identity issues in multicultural Australia. In its extreme, negative form, assumptions that certain characteristics apply to all members of an ethnic group can be attributed to racism. However, the belief that individuals who share the same ethnic background have similar needs, interests and perceptions is also reflected in business, government policy and academic research. Often, ethnic groupings used for research and policy formulation are very broad and fail to take into account within-group differences. The criteria used to assess an individuals membership of an ethnic group can be problematic. Criteria based purely on objective measures such as country of birth or ethnic ancestry do not take into account acculturation processes or the degree to which individuals consider themselves to be 'ethnic '. These objective measures are complicated further as individuals may have ethnic roots from multiple countries depending on their family composition over several generations. This theory-focused paper proposes that ethnic identity should be viewed as a subjective phenomenon where individuals are likely to align themselves with the ethnic background to which they most identify. This has implications for research and policy making in multicultural societies.

A solar collector with the absorber divided by rectangular slots

A new solar absorber structure has been proposed and studied in this paper. The metal tubes running perpendicular to a set of parallel rectangular metal fins make the solar absorber with rectangular slots. Studies on the collector were theoretically carried out in the aspects of heat transfer, thermodynamics and . hydrodynamics. The calculating methods for calculating fin efficiency F and efficiency factors of the collector F' were obtained. The results showed that the new solar collector would have the higher efficiency and better performance at higher fluid temperature than that of the traditional flat-plate collectors. A collector prototype with the new structure was built and tested. The testing results agree with our theoretical results.

Arts marketing challenges in multicultural societies

With an increasingly diverse, multicultural society in many countries, it is timely to look more closely at the current literature on arts marketing, ethnic identity and segmentation issues. The growth of diverse, multicultural societies in many countries warrants a closer examination of arts marketing and the use of ethnicity as a basis for segmentation, as these issues have implications for attracting and retaining arts audiences and other consumers of arts related activities. Researchers in the arts industry have stressed the importance of understanding the fundamentals of audience development and the ability to focus on satisfying the needs and wants of their audiences. The focus on marketing activities comes at a time when there is greater pressure on arts organisations to move beyond their traditional role as subsidized non-profit organisations in order to become more self-supporting. Internationally, audience development in the arts industry has focused on segmentation dimensions such as youth, mature aged individuals, geographic location (rural), individuals with disabilities, low income earners, and individuals with culturally diverse backgrounds. Most of these potential segments are under represented in the population of arts consumers in Australia, the United Kingdom, Singapore, and North America. Of those dimensions, segmentation of arts markets by cultural differences such as ethnic identity appears to be a somewhat under researched area. Hofstede's (1980) model of national cultural differences continues to be widely used as a basis for strategic and marketing decisions in international business. However, the cultural characteristics attributed to individuals in their country of birth are likely to change through immigration to another country. In this situation, the ability to predict the consumption behaviour of various ethnic groups is complicated by acculturation processes in which arrivals attempt to adapt to their new environment. Over time, this process has resulted in the emergence of bicultural individuals who are able to switch, at will, between their ethnic identity and an identity aligned with their host country, or a combination of both at any time. Ethnic identity and affiliation with ethnic groups can also change over time, suggesting challenges for arts marketing approaches, and the application of market segmentation theory in particular.
