A critical review of psychological instruments used in police officer selection

Purpose
The purpose of this paper is to critically examine the instruments used in the screening process, with particular attention given to supporting research validation. Psychological screening is a well-established process used in the selection of employees across public safety industries, particularly in police settings. Screening in and screening out are both possible, with screening out being the most commonly used method. Little attention, however, has been given to evaluating the comparative validities of the instruments used.

Design/methodology/approach
This review investigates literature supporting the use of the Minnesota Multiphasic Personality Inventory (MMPI), the California Personality Inventory (CPI), the Inwald Personality Inventory (IPI), the Australian Institute of Forensic Psychology's test battery (AIFP), and some other less researched tests. Research supporting the validity of each test is discussed.

Findings
It was found that no test possesses unequivocal research support, although the CPI and AIFP tests show promise. Most formal research into the validity of the instruments lacks appropriate experimental structure and is therefore less powerful as “evidence” of the utility of the instrument(s).

Practical implications
This research raises the notion that many current screening practices are likely to be adding minimal value to the selection process by way of using instruments that are not “cut out” for the job. This has implications for policy and practice at the recruitment stage of police employment.

Originality/value
This research provides a critical overview of the instruments and their validity studies rather than examining the general process of psychological screening. As such, it is useful to those working in selection who are facing the choice of psychological instrument. Possibilities for future research are presented, and development opportunities for a best practice instrument are discussed.

Outsourcing and downsizing: Processes of workplace change in public health

Throughout the 1990s, public hospitals embarked on a range of benchmarking exercises for support services, often accompanied by downsizing and, in some cases, outsourcing. These support services included clinical areas such as, radiology, pharmacy and pathology, and nonclinical areas of catering and cleaning, engineering and environmental services. The impetus for this trend was the introduction of the Federal Governments National Competition Policy with its rationale that private sector pressures and competition would make the public sector more efficient.
Through a case study approach, this paper discusses this process at two public hospitals, the aim being to investigate the reasons for outsourcing, outsourcings interconnectedness with downsizing, and the implications at the workforce level. Workplace issues discussed include consultation between management, unions and employees, changes to employee numbers and work practices, maintenance of workplace conditions, implications for staff recruitment and retention, and the relative power of management and unions. It concludes that benchmarking, outsourcing and downsizing have all been used to bring about workplace change. Whilst the choice between processes may be dependent on management perception of the workplace environment, implications for the workplace from each process have been similar.

The rough sets feature selection for trees recognition in color aerial images using genetic algorithms

Selecting a set of features which is optimal for a given task is the problem which plays an important role in a wide variety of contexts including pattern recognition, images understanding and machine learning. The concept of reduction of the decision table based on the rough set is very useful for feature selection. In this paper, a genetic algorithm based approach is presented to search the relative reduct decision table of the rough set. This approach has the ability to accommodate multiple criteria such as accuracy and cost of classification into the feature selection process and finds the effective feature subset for texture classification . On the basis of the effective feature subset selected, this paper presents a method to extract the objects which are higher than their surroundings, such as trees or forest, in the color aerial images. The experiments results show that the feature subset selected and the method of the object extraction presented in this paper are practical and effective.

A process model to support design and construction

This research is focused on developing a highly detailed understanding of current organisational interactions and information flows leading to a definition of the process model for the environment into which information and communication technology (ICT) applications will be placed. The authors of this paper propose a theoretical process model and the associated detailed information structure which reflects the complexity of information, stakeholder interaction and intellectual property concerns which are currently seen in the construction industry. This is being developed and tested against a field study renovation project. The field study project identifies information flows and interactions between stakeholders such as designers, project managers, clients, contractors, subcontractors and suppliers. The process model which is being established shows very high levels of complexity in dependencies and interdependencies between implicit and explicit information within the project design and construction teams. Without an understanding of these detailed and complex process interactions, proposals for the application of ICT to the construction industry will not reflect the requirements of those for whom they are being developed.

Evidence-based clinical policy: case report of a reproducible process to encourage understanding and evaluation of evidence

We report within a case study a reproducible process to facilitate the explicit incorporation of evidence by a multidisciplinary group into clinical policy development. To support the decision-making of a multidisciplinary Intersectoral Advisory Group (IAG) convened by the Royal Australasian College of Physicians Health Policy Unit, a systematic review of randomized controlled trials about environmental tobacco smoke and smoking cessation interventions in paediatric settings was first undertaken. As reported in detail here, IAG members were then formally engaged in a transparent and replicable process to understand and interpret the synthesized evidence and to proffer their independent reactions regarding policy, practice and research. Our intention was to ensure that all IAG members were democratically engaged and made aware of the available evidence. As clinical policy must engage stakeholder representatives from diverse backgrounds, a process to equalize understanding of the evidence and 'democratize' judgment about its implications is needed. Future research must then examine the benefits of such explicit steps when guidelines, in turn, are implemented. We hypothesize that changes to future practice will be more likely if processes undertaken to develop guidelines are transparent to clinicians and other target groups.

Interlink decision making index (IDMI) : a simple tool/concept to assist decision making for sustainability part 2 : calculation and examples of IDMI

There is an apparent gap between the LCA or other assessment's outcomes and its effective application in the decision making process. It is needed to provide to the decision makers a simple, less human interfered mechanism that integrates all the key criteria (environmental, economic, technical and safety etc.). The proposed index: Interlink Decision Making Index (IDMI) has all these features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (ie. no human weighting needed) and is able to assist the multi-criteria decision making for sustainability based on the outcomes of specific assessments (eg. LCA, BIA etc.). The index represents a pure numerical value and does not necessarily have any physical meanings, but it reflects the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (Ce) have been chosen. Then, without arbitrarily weighting process, the comparison and selection of the best possible option, ie. decision can be made based on the derived IDMI results. Two hypothetical examples are presented in the part 2 of the paper to demonstrate the application of the IDMI concept and it's differences with the traditional "tabular method" in the decision making process.

Examining the relationship between event owners and host destinations

The event sector has often come under the scrutiny of the public. A cursory glance at print and electronic media highlights some of the many negative attitudes social commentators and residents of host destinations have of special events. While there are a number of stakeholders of events, two entities which play a pivotal role in whether, when, and how events are delivered are the event governing bodies (or owners) and the host destinations. This paper examines the relationship between these two stakeholders. Research questions guiding this study are: Do event owners vary in their interactions with event destinations? Should event destinations be more discerning in their selection of the events they host? Can event destinations be more discerning in their selection of the events that they bid for?

While considerable research has focused on the relationship between event owners and host destinations during the event bidding process, this study aimed to explore the relationship more generally to provide greater insights into the event planning process. Thus, the study aimed to address a gap in knowledge about event marketing and management to understand motives for destinations to engage with event owners, and ultimately to enhance the quality of the event experience (for both attendees and non-attendees). A qualitative research approach was employed for this study, with elite interviews being the main data collection method.

The findings indicate that the relationship between event owners and host destinations can be highly problematic. A number of factors were identified as contributing to this situation, including the varying objectives that event owners have for their events; the way in which these objectives are congruent (or not) with host destinations objectives for events in their community; and the way in which a potential match or mis-match of objectives impacts a host destination’s ability to leverage an event. Overall, the researchers concluded that when there is disparity between the culture of the event owners’ organisation, and the social culture of the host destination, this situation is exacerbated. When event owners demonstrated empathy and an understanding of the host destination’s culture, and an understanding of the host destination’s aim for delivering an event, greater levels of perceived success are evident.

In the past, the bid process has been highly competitive. Host destinations have been at the mercy of event owners. However, the authors of this study indicate that as a result of this research, host destinations should be more discerning with regard to which event owners they ‘lie in bed with’ to ensure that the outcomes of the events are beneficial for their myriad stakeholders. It is acknowledged that the event planning and execution process is set within a political market square, as per Larson and Wikstrom’s (2001) suggestion, and that this context provides a fertile ground for research on this topic.

Vietnamese-born health professionals : negotiating work and life in rural Australia

Introduction: Australia is a culturally diverse nation due to migrants from a wide variety of countries creating a multicultural society. The health professions are highly valued by the younger generation of overseas-born migrants who have acculturated into Australian society; many have chosen health care as their profession in Australia. However, most migrants settle in metropolitan areas and young health professionals may find working in rural or remote Australia culturally and professionally highly challenging. The present study of migrant health professionals examined the life experiences and acculturation strategies of Vietnamese-born health professionals working and living in rural Australia. Objectives: The two main study objectives were to: (1) examine aspects of the acculturation of overseas-born and Australian-trained health professionals in the Australian health discourse; and (2) identify key coping strategies used by them when in working in the rural context.

Methods: Six overseas-born, Australian-trained health professionals were invited to participate in this qualitative study using a snowball sampling technique. The participants were all born in Vietnam and had experienced working in rural Australia. They included three medical doctors, a dentist, a physiotherapist and a nurse. The interviews were recorded and four participants also provided additional written responses to some of the open-ended interview questions. The interview data were transcribed and later coded for thematic analysis. Topics and themes that emerged focused on the issues and strategies of acculturation to the rural health context.

Results: The study showed that the acculturation process was affected by the participants’ views about and attitudes towards working in an Australian rural context. The study identified these essential strategies used by the participants in adapting to a new workplace: collaborating, distancing, adjusting, repairing, and accommodating.

Conclusion: The study provides insights into the lives of these health professionals in a rural context, and particularly their experience of cultural shock and the coping strategies they may use. A need is identified for a larger study to inform recruitment and retention of these health professionals to rural Australia, and to assist universities to prepare such students and their clinical supervisors for rural placements.

Power and politics in a system implementation

The central concern of this study is to identify the role of power and politics in systems implementation. The current literature on systems implementation is typically divided into two areas, process modelling and factor based studies. Process modelling classifies the implementation into a linear process, whereas factor based studies have argued that in order to ‘successfully’ implement a system, particular critical factors are required. This literature misses the complexities involved in systems implementation through the human factors and political nature of systems implementation and is simplistic in its nature and essentially de-contextualises the implementation process. Literature has investigated some aspects of human factors in systems implementation. However, it is believed that these studies have taken a simplistic view of power and politics. It is argued in this thesis that human factors in systems implementation are constantly changing and essentially operating in a dynamic relationship affecting the implementation process. The concept of power relations, as proposed by Foucault (1976, 1977, 1978, 1980, 1982), have been utilised in order to identify the dynamic nature of power and politics. Foucault (1978) argued that power is a dynamic set of relationships constantly changing from one point in time to the next. It is this recognition that is lacking from information systems. Furthermore, these power relations are created through the use of discourse. Discourse represents meaning and social relationships, forming both subjectivity and power relations. Discourses are also the practices of talk, text and argument that continuously form that which actors speak. A post-structuralist view of power as both an obvious and hidden concept has provided the researcher a lens through which the selection and implementation of an enterprise-wide learning management system can be observed. The framework aimed to identify the obvious process of system selection implementation, and then deconstruct that process to expose the hegemonic nature of policy, the reproduction of organisational culture, the emancipation within discourse, and the nature of resistance and power relations. A critical case study of the selection and implementation of an enterprise-wide learning management system at the University of Australia was presented providing an in-depth investigation of the implementation of an enterprise-wide learning management system, spanning five years. This critical case study was analysed using social dramas to distinguish between the front stage issues of power and the hidden discourses underpinning the front stage dramas. The enterprise-wide learning management system implemented in the University of Australia in 2003 is a system which enables academic staff to manage learners, the students, by keeping track of their progress and performance across all types of training activities. Through telling the story of the selection and implementation of an enterprise-wide learning management system at the University of Australia discourses emerged. The key findings from this study have indicated that the system selection and implementation works at two levels. The low level is the selection and implementation process, which operates for the period of the project. The high level is the arena of power and politics, which runs simultaneously to the selection and implementation process. Challenges for power are acted out in the front stage, or public forums between various actors. The social dramas, as they have been described here, are superfluous to the discourse underpinning the front stage. It is the discourse that remains the same throughout the system selection and implementation process, but it is through various social dramas that reflect those discourses. Furthermore, the enactment of policy legitimises power and establishes the discourse, limiting resistance. Additionally, this research has identified the role of the ‘State’ and its influence at the organisational level, which had been previously suggested in education literature (Ball, 1990).

Insights from research on cross-cultural validation of health-related questionnaires : the role of bilingual project workers and lay participants

This article discusses the recruitment and training of bilingual project workers and their role in data gathering; the level of comprehension of the interviewees with regard to the nature of the task and its alien nature; the contribution of social customs and expectations; the vagaries of language; the researchers' level of comprehension of data collected across a range of languages; the feelings of loss of control by the researchers over the research process; and issues of communication with bilingual project workers. The authors draw on two studies designed to assess the adequacy of questionnaire translations from English into four ethnic minority languages: Cantonese, Punjabi, Urdu and Sylheti. Bilingual project workers were recruited to carry out interviews and focus groups with the lay communities and to feed back results in English to the researchers. The authors conclude that researchers should be aware of the influence of social and contextual factors when carrying out research with ethnic minority participants mediated by bilingual project workers.

An embedded two-layer feature selection approach for microarray data analysis

Feature selection is an important technique in dealing with application problems with large number of variables and limited training samples, such as image processing, combinatorial chemistry, and microarray analysis. Commonly employed feature selection strategies can be divided into filter and wrapper. In this study, we propose an embedded two-layer feature selection approach to combining the advantages of filter and wrapper algorithms while avoiding their drawbacks. The hybrid algorithm, called GAEF (Genetic Algorithm with embedded filter), divides the feature selection process into two stages. In the first stage, Genetic Algorithm (GA) is employed to pre-select features while in the second stage a filter selector is used to further identify a small feature subset for accurate sample classification. Three benchmark microarray datasets are used to evaluate the proposed algorithm. The experimental results suggest that this embedded two-layer feature selection strategy is able to improve the stability of the selection results as well as the sample classification accuracy.

Constitutionalism and beyond the dispute between the left and right

From the constitutional point of view, all ideology in a pluralistic society structures have their own status and function. The rise of China needs a healthy, diverse and balanced thinking the situation. We need a capacity of macro-narrative and a framework to develop a macro perspective, the various ideologies put this macro, the constitutional system integration. This article is about ideology than an example, the analysis and comparison of three models. The first mode is now at in the formation and development process, and our political system to adapt to the "balanced" mode. The second model is adopted, representing the "left" "right" interest groups to reach beyond the ruling party turns around, balance of interests purpose. The third is in the process of policy formulation and selection of multi-party consultation and inclusive pattern of results of various think tanks.

This article is the second in a six-part series addressing research and the DSN. Crirical review is a key aspect of research and evidencebased care and, therefore, of clinical and professional practice. Critical review is an analytical and reflective process that involves judging the quality of research publicarions and their relevance to practice. This article oudines key aspects of how to review publications and conference presentations, how critical review applies to clinical care, and how this process om help develop writing and critical thinking skills. Also addressed are the general aspects of critical review, and a list of further reading and useful websites is provided. Specific considerations for particular research methods such as quantitative, qualitative, evaluation studies and audits will be addressed in later articles in the series.

Knowledge management culture, strategy and process in Malaysian firms

Malaysia is one of the leading countries in Asia that are at the forefront in the development of a knowledge-based economy (KBE). The Malaysian government has been making substantial investments in both physical and technological infrastructure to facilitate knowledge-intensive economic activities. Foreign and local firms in Malaysia are encouraged to take advantage of the opportunities brought by the emerging KBE. However, little is known as to how firms in Malaysia respond to this new trajectory of economic development. In particular, there is paucity in the literature as to how Malaysian firms manage knowledge in their organizations as they strive to achieve sustainable competitive performance. Little is known as to how and why firms in Malaysia develop and manage their intangible and knowledge-based resources as they operate and respond to the modern knowledge-based competitive economic arena. This paper examines a type of organizational culture that supports and promotes knowledge management (KM) within firms in Malaysia. The paper argues that KM-oriented culture shapes the overall KM strategy of firms, which consequently shapes the organizational process required to manage the firm's knowledge-based resources. The study uses survey data from a sample of 153 firms from Malaysia. Structural equation modelling was used to develop and test the measurement model of KM-oriented culture, KM strategy and KM process of the sample firms, as well as the structural model of their hypothesized relationships. The results show that firms with high level of KM-oriented culture demonstrated well-defined KM strategies. Firms that implemented well-defined KM strategies also reported that they have better KM processes in place. Building a KM-oriented culture within the organization is a pre-requisite to the implementation of any KM systems in Malaysian firms. Successful implementation of KM strategies, processes and the supporting technological infrastructure depends on whether organizational members consider KM as a norm within the firm. The study's focus on the linkages between KM-oriented culture, strategy and process in the context of Malaysian firms contributes to a more nuanced understanding of KM among firms in the Asian context in general, and in the Malaysian context in particular.
