Overcoming inconsistencies in placement assessment : the case for developmental assessment centers

Placements are integral to many university courses and to increasing student employability skills. Nevertheless, several complications, such as the assessment of placement experiences which often go against the principles of procedural justice, may limit placement effectiveness. For example, procedures are not applied uniformly across students; and evaluations of intangible qualities are susceptible to biases. As a result, effort and learning can be compromised. This paper advocates the use of developmental assessment centers to help solve these shortcomings. Developmental assessment centers are often used in organizations to evaluate capabilities of individuals and to facilitate development. Participants complete a series of work related and standardized tasks. Multiple raters then utilize a systematic approach to evaluate participants on a range of competencies, and consequently present constructive feedback to facilitate learning. Therefore, developmental assessment center principles match the key determinants of procedural justice and thus overcome many problems with traditional placement assessments.

Analysing stakeholder-associated risks in green buildings : a social network analysis method

In the research of risk associated with developing energy and water efficient green buildings, previous studies had mainly focused on "what the risks are and how the risks may impact on project objectives", which were from an inward looking self-perspective and treated the risks in isolation from one another. While intensive research efforts have been dedicated to risk identification, assessment, classification, prioritisation and mitigation, a research gap exists, that is previous studies had ignored the fact that most risks are interrelated and associated with internal or external project stakeholders. To remedy the gap, this current research developed and presented a SNA (Social Network Analysis) based stakeholder-associated risk analysis method to assess risks in green buildings and the interactions between the risks. A case study has been conducted to demonstrate and validate this method. This research contributes to the development of a new theory to model the interdependent and interactive relationships of risks by using SNA as a methodology. This research should broaden project managers' awareness of the influential risks in green building and enhance their ability to perceive, understand, assess, and mitigate the risks in an effective and efficient way, thereby achieving higher performance in strategic risk management and stakeholder communication in green building development.

Recognising user identity in twitter social networks via text mining

Social networks have become a convenient and effective means of communication in recent years. Many people use social networks to communicate, lead, and manage activities, and express their opinions in supporting or opposing different causes. This has brought forward the issue of verifying the owners of social accounts, in order to eliminate the effect of any fake accounts on the people. This study aims to authenticate the genuine accounts versus fake account using writeprint, which is the writing style biometric. We first extract a set of features using text mining techniques. Then, training of a supervised machine learning algorithm to build the knowledge base is conducted. The recognition procedure starts by extracting the relevant features and then measuring the similarity of the feature vector with respect to all feature vectors in the knowledge base. Then, the most similar vector is identified as the verified account.

Personal ICT Ensembles and Ubiquitous Information Systems Environments: Key Issues and Research Implications

Personal information and communication technologies (ICTs) have become commonplace. Today many people own, or have access to, a range of different computing and communication devices, information technologies, and services, which they incorporate into their everyday routines. Increasingly, these technologies impact the way that individuals work, socialize, and play. Workers are bringing their personal ICTs to the office, and organizations are tailoring their computing environments toward ubiquitous integration with personal ICTs. These developments are opening up new ways of working, but they also create new challenges for organizations in accommodating this “nonaffiliated” use as part of their information systems environments. In this article we propose a framework for analyzing the composition and impact of personal ICT ensembles. The framework is positioned as pre-theory that invites further development and empirical testing. We illustrate how the proposed framework could be applied to consider personal ICT use across the work/home context. Several implications stemming from the notion of a personal ICT ensemble are highlighted, including practical considerations for nonaffiliated use in organizations. We conclude with suggestions for further development of the proposed framework.

Matrix-based pairwise key establishment in wireless mesh networks using deployment knowledge

Due to the nature of wireless transmission, communication in wireless mesh networks (WMNs) is vulnerable to many adversarial activities including eavesdropping. Pairwise key establishment is one of the fundamental issues in securing WMNs. This paper presents a new matrix-based pairwise key establishment scheme for mesh clients. Our design is motivated by the fact that in WMNs, mesh routers are more powerful than mesh clients, both in computation and communication. By exploiting this heterogeneity, expensive operations can be delegated to mesh routers, which help alleviate the overhead of mesh clients during key establishment. The new scheme possesses two desirable features: (1) Neighbor mesh clients can directly establish pairwise keys; and (2) Communication and storage costs at mesh clients are significantly reduced.

'Very inflated rhetoric polysyllables and so on': the public intellectual and jargon in the academy

The public intellectual, by their very definition, aims to reach a large sector of the public or publics. This requires proficiency, or at least the capacity to communicate in a variety of forms. As a large proportion of the public, to which the public intellectual appeals, is an online or cyber public, the importance of blogs in a computer-literate public cannot be under-estimated. The immediacy of the blog and the way in which an online presence facilitates immediate communication between the public and the public intellectual through the posting of comments online allow for a broad recognition of the intellectual in the public arena. My arguments will hinge on my interviews with contemporary American public intellectuals (Noam Chomsky, Howard Zinn, Todd Gitlin, Camille Paglia and Stephen Greenblatt) and their views on communication in a society experiencing a decline in the publication of print media.

Security and trust in opportunistic networks - a survey

Opportunistic networks or OppNets refer to a number of wireless nodes opportunistically communicating with each other in a form of “Store–Carry–Forward”. This occurs when they come into contact with each other without proper network infrastructure. OppNets use wireless technologies, such as IEEE 802.11, WiMAX, Bluetooth, and other short-range radio communication. In OppNets, there is no end-to-end connection between the source and the destination nodes, and the nodes usually have high mobility, low density, limited power, short radio range, and often subject to different kinds of attacks by malicious nodes. Due to these characteristics and features, OppNets are subject to serious security challenges. OppNets strongly depend on human interaction; therefore, the success of securing such networks is based on trust between people. This survey includes the security approaches in OppNets and techniques used to increase their security levels.

Challenges and opportunities of undertaking a video ethnographic study to understand medication communication

AIMS AND OBJECTIVES: To examine the challenges and opportunities of undertaking a video ethnographic study on medication communication among nurses, doctors, pharmacists and patients. BACKGROUND: Video ethnography has proved to be a dynamic and useful method to explore clinical communication activities. This approach involves filming actual behaviours and activities of clinicians to develop new knowledge and to stimulate reflections of clinicians on their behaviours and activities. However, there is limited information about the complex negotiations required to use video ethnography in actual clinical practice. DESIGN: Discursive paper. METHOD: A video ethnographic approach was used to gain better understanding of medication communication processes in two general medical wards of a metropolitan hospital in Melbourne, Australia. This paper presents the arduous and delicate process of gaining access into hospital wards to video-record actual clinical practice and the methodological and ethical issues associated with video-recording. CONCLUSIONS: Obtaining access to clinical settings and clinician consent are the first hurdles of conducting a video ethnographic study. Clinicians may still feel intimidated or self-conscious in being video recorded about their medication communication practices, which they could perceive as judgements being passed about their clinical competence. By thoughtful and strategic planning, video ethnography can provide in-depth understandings of medication communication in acute care hospital settings. Ethical issues of informed consent, patient safety and respect for the confidentiality of patients and clinicians need to be carefully addressed to build up and maintain trusting relationships between researchers and participants in the clinical environment. RELEVANCE TO CLINICAL PRACTICE: By prudently considering the complex ethical and methodological concerns of using video ethnography, this approach can help to reveal the unpredictability and messiness of clinical practice. The visual data generated can stimulate clinicians' reflexivity about their norms of practice and bring about improved communication about managing medications.

Hydraulic economy and logographic writing in ancient China: factor of topography

Chinese civilisation is characterised by two distinctive features – a strong centralised administration and the system of logographic writing. This paper investigates nature’s powerful impacts on human development, in terms of organisation and communication in ancient China. It argues that ancient China’s topography played a crucial role in the formation of ancient Chinese civilisation and its hydraulic economy pushed the state stronger than society, hence a strong centralised government emerged.

The construction of power in family medicine bedside teaching: a video observation study

INTRODUCTION: Bedside teaching is essential for helping students develop skills, reasoning and professionalism, and involves the learning triad of student, patient and clinical teacher. Although current rhetoric espouses the sharing of power, the medical workplace is imbued with power asymmetries. Power is context-specific and although previous research has explored some elements of the enactment and resistance of power within bedside teaching, this exploration has been conducted within hospital rather than general practice settings. Furthermore, previous research has employed audio-recorded rather than video-recorded observation and has therefore focused on language and para-language at the expense of non-verbal communication and human-material interaction. METHODS: A qualitative design was adopted employing video- and audio-recorded observations of seven bedside teaching encounters (BTEs), followed by short individual interviews with students, patients and clinical teachers. Thematic and discourse analyses of BTEs were conducted. RESULTS: Power is constructed by students, patients and clinical teachers throughout different BTE activities through the use of linguistic, para-linguistic and non-verbal communication. In terms of language, participants construct power through the use of questions, orders, advice, pronouns and medical/health belief talk. With reference to para-language, participants construct power through the use of interruption and laughter. In terms of non-verbal communication, participants construct power through physical positioning and the possession or control of medical materials such as the stethoscope. CONCLUSIONS: Using this paper as a trigger for discussion, we encourage students and clinical teachers to reflect critically on how their verbal and non-verbal communication constructs power in bedside teaching. Students and clinical teachers need to develop their awareness of what power is, how it can be constructed and shared, and what it means for the student-patient-doctor relationship within bedside teaching.

Attitudinal and behavioural approaches to improving waste management on construction projects in Australia: Benefits and limitations

This research aims to understand the attitudes and behaviours of stakeholders towards waste management and consequently identify ways of improving waste management practices in construction projects. Semi-structured interviews were conducted. The findings reveal that most of the decisions in construction projects are based on their financial returns unless there is a special requirement to comply with Green Star or any other sustainable building rating system. Even though there is a trend towards environment-friendly construction, contractors are favourable towards methods involving financial incentives. Results also indicate that private developers are more price-driven compared with government clients. Findings reveal the necessity of enforcing legislation to improve waste management practices until such practices become culturally embedded in organizations across the supply chain. Similarly, end users' motivation towards waste management was also identified as a key to encouraging stakeholders of construction projects and improving their attitudes and behaviours towards waste management practices.

Back to the future: Warlpiri encounters with drawings, country and others in the digital age

Since the early 1900s, Warlpiri people living in the central desert region of Australia have experienced an intense process of adaption to the changing circumstances of postcolonial life. From the earliest days, their encounters with kardiya, non-Aboriginal people, have been mediated by diverse visual technologies that have, over time, become integral to the ways Warlpiri orient themselves to each other and their wider world. In this paper I trace the key elements of the complex visual environment that has emerged from this history of mediation. The central part of the paper considers events around the repatriation to Warlpiri communities in 2011 of a collection of drawings made in the 1950s by their forebears.In responses to a medium that once was new but now is old, several points of interest emerge, among them a clear sense of a hierarchy of value Warlpiri apply to modes of visual communication. In the context of the return of the drawings, the significance Warlpiri ascribe to other visual media comes to the fore. I consider some of the ways visual forms are deployed in support of public projections of cultural identity on the one hand and everyday modes of expression and address on the other. The paper’s central argument is that contemporary Warlpiri attitudes to images – whether they be drawn, painted or broadcast – reveal the complex postcolonial workings of mimetic desire.

Standard setting in specific-purpose language testing: what can a qualitative study add?

This paper explores the views of nursing and medical domain experts in considering the standards for a specific-purpose English language screening test, the Occupational English Test (OET), for professional registration for immigrant health professionals. Since individuals who score performances in the test setting are often language experts rather than domain experts, there are possible tensions between what is being measured by a language test and what is deemed important by domain experts. Another concern is a lack of qualitative research on the process of the standard setting. To date, no published qualitative work has been identified about the contributions of domain experts in the standard setting for healthcare communication. In this study, a standard-setting exercise was conducted for the speaking component of the OET, using judgements of nursing and medical clinical educators and supervisors. In all, 13 medical and 18 nursing clinical educators and supervisors rated medical and nursing candidate performances respectively. These performances were audio-recorded OET role-plays that were selected across a range of proficiency levels. Domain experts were invited to comment on the basis of their decisions and the extent of alignment between these decisions and the criteria used to assess performance on the OET. Nursing and medical domain experts showed that they attended to all of the OET criteria in making their decisions about standards. However, clinical scenario simulation also invited judgements of clinical competence from participants, even where they knew that clinical competence should be excluded from their decision-making. Another concern related to the authenticity limitations of the role-play tasks as evidence of readiness to handle communication in the workplace. Overall, findings support the value of qualitative evidence from the standard setting in providing insight into the factors informing and impeding decision-making.

Machine-to-machine communications with in-network data aggregation, processing, and actuation for large-scale cyber-physical systems

Machine-to-Machine (M2M) paradigm enables machines (sensors, actuators, robots, and smart meter readers) to communicate with each other with little or no human intervention. M2M is a key enabling technology for the cyber-physical systems (CPSs). This paper explores CPS beyond M2M concept and looks at futuristic applications. Our vision is CPS with distributed actuation and in-network processing. We describe few particular use cases that motivate the development of the M2M communication primitives tailored to large-scale CPS. M2M communications in literature were considered in limited extent so far. The existing work is based on small-scale M2M models and centralized solutions. Different sources discuss different primitives. Few existing decentralized solutions do not scale well. There is a need to design M2M communication primitives that will scale to thousands and trillions of M2M devices, without sacrificing solution quality. The main paradigm shift is to design localized algorithms, where CPS nodes make decisions based on local knowledge. Localized coordination and communication in networked robotics, for matching events and robots, were studied to illustrate new directions.

ED-HOME: improving educator confidence and patient education in the emergency department

BACKGROUND: Barriers to effective patient communication in the emergency department (ED) are well recognised; time, resources and staff and consumer expectations. This project aimed to improve the quality of health education provided in the ED by increasing nurses' confidence as educators.

METHOD: By providing a staff information package including the introduction of a new structured education tool; ED-HOME, and by assessing the confidence and self-efficacy of the nurses in the process, we hoped to determine if an improvement in practice and confidence was achieved. A quantitative, pre and post-test questionnaire comparison study was undertaken before and after a four week implementation period. The project examined the attitudes and practices of registered emergency nurses and was conducted in one metropolitan emergency department.

RESULTS: Results indicated that nurse confidence and self-efficacy improved by using the new structured ED-HOME format and both staff satisfaction and education competence increased. Participants positively responded to the new tool and recommended future use in the ED.

CONCLUSION: This project demonstrates that if emergency nurses feel more confident with their educating practices and by using a structured format, patients will benefit from better quality patient education provided in the ED.
