Acquisition of invasion‐inhibitory antibodies specific for the 19‐kDa fragment of merozoite surface protein 1 in a transmigrant population requires multiple infections

Antibodies against the 19 kDa C‐terminal fragment of merozoite surface protein 1 (MSP119) are a major component of the invasion‐inhibitory response in individuals immune to malaria. We report here the acquisition of MSP119‐specific invasion‐inhibitory antibodies in a group of transmigrants who experienced their sequential malaria infections during settlement in an area of Indonesia where malaria is highly endemic. We used 2 transgenic Plasmodium falciparum parasite lines that expressed either endogenous MSP119 or the homologous region from P. chabaudi to measure the MSP119‐specific invasion‐inhibitory antibodies. The results revealed that the acquisition of MSP119‐specific invasion‐inhibitory antibodies required 2 or more P. falciparum infections. In contrast, enzyme‐linked immunosorbent assays on the same serum samples showed that MSP119‐specific antibodies are present after the first malaria infection. This delay in the acquisition of functional antibodies by residents of areas where malaria is endemic is consistent with the observation that multiple malaria infections are required before clinical immunity is acquired.

Gatekeeper influence on food acquisition, food preparation and family diet

The problems associated with overweight and obesity has focused attention on obesogenic, or obesity promoting environments. The home environment, in particular the role of the main food gatekeeper, has come under particular scrutiny for its impact on the family diet (Campbell et al, 2007; Coveney, 2004; Crawford et al, 2007). 326 US and 323 Australian gatekeepers are studied to understand relationships between healthy eating capability, food acquisition and food preparation behaviours, and satisfaction with the household diet. The results suggest that gatekeeper attitudes and perceived control over family diet play a significant role in shaping food-related behaviours and diet satisfaction. Impulsiveness, focusing on freshness, meal planning, and vegetable prominence in meals are also important behavioural factors for satisfaction with diet.

The acquisition of generic skills of culturally-diverse student cohorts

The changing nature of higher education and the structure of graduate labour markets have increased emphasis on employability and graduate outcomes. Universities have responded to this changed environment by embedding generic skills in the curriculum. This paper examines the generic skills that students perceived they acquired in their accounting studies in preparation for graduate employment. Given the changed background profiles of students studying accounting degree in Australia, and the employment difficulties they encounter on graduation, the study specifically addresses the perceptions of students from diverse cultural backgrounds. The findings demonstrate that, overall, students believed that their accounting course assisted in developing generic skills, while differences in perceptions were identified between different cultural cohorts. The research highlights the need to develop educational practices which embed generic skills development in the curriculum in a way that maximises the opportunities for culturally-diverse student cohorts to enhance their employment outcomes on graduation.

Social intelligence and top management team: an exploratory study of external knowledge acquisition for strategic change in global IT service providers in India

This paper focuses on the processes by which firms, particularly knowledge intensive firms, can augment their overall knowledge stock by tapping into external sources of knowledge. It is argued that Top Management Teams' (TMTs') social intelligence is a critical learning capability in acquiring external knowledge that leads to strategic change. Social intelligence involves social awareness, social understanding and social skills. The study draws from the experience of 11 of the largest Information Technology Service Providers (ITSPs) in India and based on in-depth interviews. The findings show that TMTs' learning capability in the context of social intelligence to interact with external stakeholders is important to ITSPs in facilitating external knowledge acquisition and allowing new knowledge emerge within and across networks. The findings provide significant insights into ITSPs emerging in other developing countries such as in China. Research limitation and future research direction are also provided.

Learners' incidental vocabulary acquisition : a case on narrative and expository texts

This study was intended to determine whether or not the genre of a reading text affects the incidental vocabulary acquisition of L2 learners while reading. To this aim, 40 Iranian EFL students whose vocabulary knowledge was within a limited range (already determined by Nation’s Vocabulary Levels Test) were divided into two groups of 20 each for the reading sections. The Narrative Group comprised the participants who read the narratives, and the Expository Group were those who read the expository texts. Three types of vocabulary tests (i.e., Form recognition, Meaning translation and Multiple-choice items) were administered after the reading sessions to assess the incidental vocabulary gains of the participants. Overall, this study demonstrated the relative superiority of expository texts over narratives in terms of enhancing readers' incidental acquisition of unknown words. It is argued that depending on the genre of a text, readers will invest processing resources with different depths and varying degrees of cognitive elaboration for the task of comprehension.

Digital natives? : new and old media and children’s language acquisition

The current generation of young children has been described as “digital natives”, having been born into a ubiquitous digital media environment. They are envisaged as educationally independent of the guided interaction provided by “digital immigrants”: parents and teachers. This paper uses data from the multiples waves of the Longitudinal Study of Australian Children (LSAC) to study the effect of various media on children’s development of vocabulary and traditional literacy. Previous research has suggested that time spent watching television is associated with less time spent reading, and ultimately, with inferior educational outcomes. The early studies of the “new” digital media (computers, games consoles, mobile phones, the Internet, etc.) assumed these devices would have similar effects on literacy outcomes to those associated with television. Moreover, these earlier studies relied on poorer measures of time spent in media use and usually did not control for the context of the child’s media use. Fortunately, LSAC contains measures of access to digital devices; parental mediation practices; the child’s use of digital devices as recorded in time use diaries; direct measures of the child’s passive vocabulary; and teachers’ ratings of the child’s literacy. The analysis presented shows the importance of the parental context framing the child’s media use in promoting the acquisition of vocabulary, and suggests that computer (but not games) use is associated with more developed language skills. Independently of these factors, raw exposure to television is not harmful to learning, as previously thought.

Innovative approaches to land acquisition and conservation management : the case of Fish River Station, Northern Territory

There has been a dramatic increase in the area that is within the National Reserve System since 2000 – from around 60 million hectares to around 100 million in 2008. This dramatic increase can be attributed to Indigenous Protected Areas and the acquisition of private or leasehold land for either addition to the public protected area estate or management as private protected areas. This growth has also been strategic, increasingly the reservation status of the most underreserved bioregions. However, the reality is the land acquisition has slowed since the global financial crisis of the late 2000s and this has led to new models with different partners coming to the fore. This chapter highlights one of those new models – the acquisition of Fish River Station in the Northern Territory for conservation.

Effects of new and old media on young children’s language acquisition, development, and early literacy : findings from a longitudinal study of Australian children

The current generation of young children has been described as “digital natives”, having been born into a ubiquitous digital media environment. They are envisaged as educationally independent of the guided interaction provided by “digital immigrants”: parents and teachers. This paper uses data from the Longitudinal Study of Australian Children (LSAC) to study children’s (aged 0-8 years) development of vocabulary and traditional literacy; access to digital devices; parental mediation practices; the child’s use of digital devices as recorded in time-diaries and, finally, the association between patterns of media use and family contexts on children’s learning. The analysis shows the importance of the parental context framing media use in acquisition of vocabulary, and suggests that computer (but not games) use is associated with more developed language skills. Independently of these factors raw exposure to television is not harmful to learning.

Modelling skill acquisition in acquired brain injury

Acquired brain injury (ABI) is a debilitating condition often requiring extensive rehabilitation. Although cognitive rehabilitation is concerned with overcoming a skills deficit, the application of skill acquisition research in this context has been non-existent. Examining post-injury learning in terms of the qualitative variables associated with different phases of skill acquisition is likely to be beneficial in assessing patient status and monitoring progress, as well as identifying changing needs over the course of learning. However, current models of skill acquisition overlook the potential impact of variables such as emotion, implicit learning, metacognition, motivation, and strategies that can be leveraged to improve skill acquisition. The current paper attempts to lay the groundwork for modelling and improving skill acquisition in ABI.

Process in skill acquisition : motivation, interruptions, memory, affective states, and metacognition

Models of skill acquisition, such as Ackerman's (1988) theory of skill acquisition, largely ignore the experiences and dynamic internal processes of a person while learning a skill (e.g., how they feel, what strategies they are using, the role of the external environment). Riding and Powell (1993) suggested that the information-processing model (a common conceptualisation of learning and thinking) is an inadequate model to explain the complexities of human brain functions. These models are largely holistic, and do not provide detail about the qualitative aspects of a person's learning experience. This paper attempts to highlight the importance of a dynamic description of skill acquisition and to “unpack” the skill acquisition stages, with a focus given to process rather than performance or outcome. Learning more about what is going on “inside people's heads” whilst learning a skill, and what feelings or affective states are present, can inform both skill acquisition theory and various practical issues, such as why some training programs fail and some succeed. The role of emotions, motivation, environment, and other factors; the concepts of skill and ability; and various theories of skill acquisition are discussed. This highlights missing elements in the typical cognitive experimental focus. The concept of process itself is explored, with a focus on learning in general. Process-oriented factors such as motivation, memory, interruptions, emotion, and metacognition are investigated in relation to skilled performance. Areas for future research and some practical implications for training are outlined.

An investigation into the drivers of Australian REIT merger and acquisition announcements

Purpose – The purpose of this paper is to use Australian Real Estate Investment Trust (A-REIT) data to empirically examine potential influencing factors on A-REITs becoming a bidder or a target in the mergers and acquisitions (M&A) area.

Design/methodology/approach – This study uses logistic regression analysis to investigate the odds of publically traded A-REITs being either a bidder or a target as a function of a number of financial and corporate governance variables.

Findings – Prior research in the US REIT M&A area has shown that target size is inversely related to takeover likelihood; in contrast, the authors’ Australian results show that size has a positive impact. Prior research on share price and asset performance has shown that underperformance increases the odds of an entity becoming a target, but this paper’s results further support these findings and provide confirmation of the inefficient management hypothesis. For acquirers it was found that leverage, cash balances, management structure, the level of shares held by related parties and the global financial crisis have an important impact on bidder likelihood.

Practical implications – Given that the literature suggests that investors can earn significant positive abnormal returns by owning targets, but incur significant abnormal losses by owning bidders, at announcement, this study will be useful to fund managers and other investors in A-REITs by investigating the characteristics of those firms that become targets and bidders.

Originality/value – This paper adds to the recent US REIT M&A literature by examining the second biggest REIT market in the world and reporting a number of factors that might influence A-REITs to become targets or bidders.
