Keyword search for building service-based systems

With the fast growth of applications of service-oriented architecture (SOA) in software engineering, there has been a rapid increase in demand for building service-based systems (SBSs) by composing existing Web services. Finding appropriate component services to compose is a key step in the SBS engineering process. Existing approaches require that system engineers have detailed knowledge of SOA techniques which is often too demanding. To address this issue, we propose KS3 (Keyword Search for Service-based Systems), a novel approach that integrates and automates the system planning, service discovery and service selection operations for building SBSs based on keyword search. KS3 assists system engineers without detailed knowledge of SOA techniques in searching for component services to build SBSs by typing a few keywords that represent the tasks of the SBSs with quality constraints and optimisation goals for system quality, e.g., reliability, throughput and cost. KS3 offers a new paradigm for SBS engineering that can significantly save the time and effort during the system engineering process. We conducted large-scale experiments using a real-world Web service dataset to demonstrate the practicality, effectiveness and efficiency of KS3.

In search of peaceful playgrounds

Recess is often thought of as a time to escape from the classroom, from work and from the constant gaze of the teacher. It was a peaceful and joyous time when most children occupied themselves in active play and the odd incident was quickly resolved with the help of the teacher on 'yard duty'. Not so any more. The playground is now a 'problem' in many schools largely because of the bullying behaviour occurring there. This paper discusses the relative merits of the strategies schools are implementing in an effort to deal with the bullying behaviour and suggests that more thought might be given to improving the playground environment itself as a way of addressing the problems.

Adolescent parenthood : a costly mistake or a search for love?

Family life is changing worldwide and an increasing number of women are choosing single parenthood. Adolescents who become pregnant and early childbearers do not always become pregnant unintentionally; some actively plan pregnancy while others are ambivalent mainly about the timing. This paper reports on a study using an ethnographic approach that explored the mothering experiences of five sole-supporting Australian teenage mothers who had a child over six months of age. It focuses on the story of one of them, a young woman who gave birth at 16 and set up home for herself and her son. Early childbearing is often a response to adverse social conditions such as poverty or homelessness and is not uncommonly chosen by teenage girls from socially deprived backgrounds. Educational and employment opportunities may be limited, whilst motherhood may provide a purpose in life when few other options are possible. Young women who make this choice need comprehensive services to support them in the parenting role, including appropriate health care, welfare and housing benefits, and support in dealing with parenting, a role which they may greatly desire but are not automatically well prepared for.

Black and white is always grey-the power of the police to conduct a strip search in Victoria

The performance of a strip search by a police officer is a serious interference with the liberty and dignity of an individual. However, it is considered by police to be an important part of their law enforcement armory and one that is increasingly necessary to utilise to assist in the investigation and prosecution of drug-related crimes. This article considers the troublesome issue of whether and in what circumstances the common law may extend to police the power to conduct a strip search. In addition, there is an examination of the statutes and regulations that purportedly give police in Victoria the power to strip search with particular attention given to ss 81 and 82 of the Drugs, Poisons and Controlled Substances Act 1981 (Vic).

Methodological and conceptual issues in the search for a relationship between animal body-size distributions and benthic habitat architecture

Benthic ecologists have studied the distribution of animal body sizes because it is a form of ‘taxon-free’ classification that may be a useful metric for describing variation within and between ecological communities. In particular, the idea that the allometry of physiological and life-history traits may control species composition and relative abundances implies a functional link between body-size distributions and communities. The physical structure of aquatic habitats has often been cited as the mechanism by which habitat may determine body-size distributions in communities. However, further progress is hindered by a lack of theoretical clarity regarding the mechanisms that connect body size to the characteristics of ecological communities, leading to methods that may obscure interesting trends in body-size data. This review examines the methodological and conceptual issues hindering progress in the search for a relationship between animal body size and habitat architecture and suggests ways to resolve these issues. Problems are identified with current methods for the measurement of animal body size, the data and measures used to quantify body-size distributions and the methods used to identify patterns therein. Fundamentally, renewed emphasis on the mechanisms by which animal body sizes are influenced by habitat architecture is required to refine methodology and synthesise results from pattern-seeking and mechanistic studies.

Principal selection: homosocialibility, the search for security and the production of normalized principal identities

Researchers investigating the decline of potential applicants for principalships have demonstrated that teachers perceive there to be a significant problem in current selection procedures. This article reports an investigation in two Australian states into principal selection. Drawing on a corpus of interviews, two case studies and administrative guidelines, we highlight five key problems in the interview process: (1) the dependence of selection panels on a written application; (2) the dilemma of experience versus potential; (3) the covert rule about the appointment of preferred applicants; (4) the quandary of panel competency; and (5) the evidence of inconsistency of decisions. We argue that the selection process amounts to a reproductive technology which, in the quest for certainty and safety, results in particular kinds of people being successful. This amounts we suggest, whether the selection process is managed by progressive or conservative personnel, to a form of homosociability the tendency to select people just like oneself.

A similarity search algorithm to predict protein structures

Accurate prediction of protein structures is very important for many applications such as drug discovery and biotechnology. Building side chains is an essential to get any reliable prediction of the protein structure for any given a protein main chain conformation. Most of the methods that predict side chain conformations use statistically generated data from known protein structures. It is a computationally intractable problem to search suitable side chains from all possible rotamers simultaneously using information of known protein structures. Reducing the number of possibility is a main issue to predict side chain conformation. This paper proposes an enumeration based similarity search algorithm to predict side chain conformations. By introducing “beam search” technique, a significant number of unrelated side chain rotamers can easily be eliminated. As a result, we can search for suitable residue side chains from all possible side chain conformations.

The propensity evidence conundrum: a search for doctrinal consistency

Definition of propensity evidence - defining the operation and scope of the outlined rules under the current common law doctrine and statutes of Australia - how it differs from the relationship and res gestae species of character evidence.

International sentencing law: in search of a justification and coherent framework

An international sentencing jurisprudence is emerging from the decisions by the International Criminal Tribunal for the Former Yugoslavia (ICTY or the Yugoslav tribunal) and the International Criminal Tribunal for Rwanda (ICTR or the Rwanda tribunal) (collectively, 'the tribunals'). This article examines international sentencing law and practice and discusses the justification for the practice. International sentencing law has several objectives. The main goals are reconciliation, deterrence, retribution and rehabilitation. The sentencing inquiry is marked by a high degree of discretion and has resulted in sentencers developing a large amount of aggravating and mitigating considerations, such as being in a position of authority, remorse and good character. It is argued that the current international sentencing approach is flawed - fundamentally so. Most of the stated goals of international sentencing in the form of reconciliation, retribution and rehabilitation are either highly speculative or misguided. The only justification for the practice is general deterrence. This is, however, significantly undermined by the selective and infrequent enforcement of crimes within the jurisdiction of such tribunals. The stated aggravated and mitigating considerations are not valid given that they are not justified by reference to the stated aims of sentencing and only serve to undermine the search for a penalty which is commensurate the serious of the offence. This article suggests a coherent framework for international sentencing policy and practice.

An approach to search and exploration through mixed-initiative

Generative design environments need support for human intervention as well as sound computational formalisms. A systematic approach to integrating the two, formal generation and the exploratory, is lacking. In this paper, we posit the possibility of a design support system that combines formal search with user driven exploration. Our approach is to cast the interaction between the user and the generative formalism as agent collaboration in a mixed-initiative environment. We describe the role of interaction and agency in an experimental mixed-initiative design support system, FOLDS and demonstrate its application.

Decades of research efforts to link economic and environmental performance: still data in search of a theory?

With the proliferation of social investment vehicles, stakeholders, particularly investors, are increasingly aware of the relationship between economic, social and environmental performance, and disclosure to external parties. This is particularly evident in The Securities and Exchange Commission's Environmental Disclosure Rules. The thesis of this paper is that, after three decades of academic and professional research efforts, there are still no firm proactive guidelines to firmly link the financial performance with environmental and social performance. The purpose of this paper is to revisit empirical research efforts spanning three decades in order to delineate potential links that may assist in systematic, comparable reporting

An empirical study of encoding schemes and search strategies in discovering causal networks

Efficiently inducing precise causal models accurately reflecting given data sets is the ultimate goal of causal discovery. The algorithm proposed by Wallace et al. [10] has demonstrated its ability in discovering Linear Causal Models from data. To explore the ways to improve efficiency, this research examines three different encoding schemes and four searching strategies. The experimental results reveal that (1) specifying parents encoding method is the best among three encoding methods we examined; (2) In the discovery of linear causal models, local Hill climbing works very well compared to other more sophisticated methods, like Markov Chain Monte Carto (MCMC), Genetic Algorithm (GA) and Parallel MCMC searching.

A comparison of search functions and other navigational tools provided on government websites

This paper reports the outcomes of a study that evaluated the effectiveness of search functions compared to other navigational tools available on government websites. The study used an observation exercise triangulated with a post observation interview. Results suggest that while there wasn't any significant difference in effectiveness between search functions and other navigational tools, the skill with which the search function is implemented and participants' familiarity with the website, are fundamental determinants of users' opinions. Implications of the findings for research and practice are discussed.

Adaptive communal detection in search of adversarial identity crime

This paper is on adaptive real-time searching of credit application data streams for identity crime with many search parameters. Specifically, we concentrated on handling our domain-specific adversarial activity problem with the adaptive Communal Analysis Suspicion Scoring (CASS) algorithm. CASS's main novel theoretical contribution is in the formulation of State-of- Alert (SoA) which sets the condition of reduced, same, or heightened watchfulness; and Parameter-of-Change (PoC) which improves detection ability with pre-defined parameter values for each SoA. With pre-configured SoA policy and PoC strategy, CASS determines when, what, and how much to adapt its search parameters to ongoing adversarial activity. The above approach is validated with three sets of experiments, where each experiment is conducted on several million real credit applications and measured with three appropriate performance metrics. Significant improvements are achieved over previous work, with the discovery of some practical insights of adaptivity into our domain.
