Abstract:
Purpose – The purpose of this paper is to examine the contribution of modern correctional service in health promotion exemplified by the case study of Norwegian health promotion policies in prison settings. Design/methodology/approach – This paper applies a two-fold methodology. First a narrative systematic literature review based on the Norwegian policy documents relevant for correctional settings is conducted. This is followed by a general review of the literature on the principles of humane service delivery in offender rehabilitation. Findings – Alongside the contribution of the Risk-Need-Responsivity Model in corrections and prevention of reoffending, the findings demonstrate an evident involvement of Norway in health promotion through authentic health promoting actions applied in prison settings. The actions are anchored in health policy's overarching goals of equity and “health in all public policy” aiming to reduce social inequalities in population health. Originality/value – In order to achieve a potential success of promoting health in correctional settings, policy makers have much to gain from endorsing a dialogue that respects the unique contributions of correctional research and health promotion. Focussing on inter-agency partnership and interdisciplinary collaboration between humane services may result in promising outcomes for individual, community and public health gain. The organizational factors and community involvement may be a significant aspect in prisoner rehabilitation, reentry and reintegration.

Abstract:
Purpose – The purpose of this paper is to explore the complex factors associated with informed consent in probation and parole settings. Design/methodology/approach – The author conducted a literature review exploring informed consent in correctional settings. To identify articles for review, the author searched electronic peer-reviewed literature databases for articles on: informed consent, corrections, probation, parole, voluntariness, and coercion. Findings – There is evidence in the literature to suggest that the informed consent process is significantly more complicated within correctional settings than in civilian contexts. The use of implicit and explicit coercion and determining an offender’s voluntariness status may be a problematic prospect unique to the setting. This manuscript makes recommendations to ensure informed consent is truly obtained and to safeguard client welfare. Originality/value – There is a paucity of literature on providing mental health services in probation and parole settings. Furthermore, this paper is unique in discussing factors associated with the informed consent process in that context.

Abstract:
Central nervous system dysfunction is an important factor to consider in inmate management. Unfortunately, this issue frequently is neglected in correctional settings. This article discusses several management and rehabilitation issues for inmates with brain impairment. The authors propose a general neuropsychological screening approach for the correctional psychologist that will provide data to facilitate numerous inmate disposition decisions. Moreover, this screening approach is time and cost efficient, relatively easy to administer and score, and likely to be sensitive to a variety of brain pathologies.

Abstract:
Despite the critical inmate need for correctional mental health services, little attention is paid to those in training to provide such services. The present study fills this gap by examining, across 25 years, 896 predoctoral psychology interns who matched for and completed a 1-year federal corrections internship. Student characteristics, their graduate training programs, and postinternship hiring outcomes are presented. More women and students with prior clinical experience in criminal justice settings have, through the years, entered into internships in correctional settings. Outcome data suggest that more than half the graduate students find employment in correctional settings after completion of internship and that having criminal justice experiences prior to internship and receiving training in more urban locations was related to such hires. Implications for training and recruiting a strong psychology services workforce in corrections are discussed.

Abstract:

Purpose. The purpose of this research was to examine how inmate horticulture programs have emerged and have been replicated in an effort to rehabilitate individuals, curtail spending, and reduce recidivism. The research explores how food justice and drug policy intersect, examining the roles of classism and racism and taking note of factors influencing recidivism.

Theoretical Framework. Diffusion of innovation analyzes the adoption of a new idea, technique, product, or service, focusing on how it is communicated and adopted by a social system over a period of time. It is necessary to understand the relationship among culture, values, existing practices, and political/social/environmental climate in order to facilitate the adoption of a new innovation.

Methodology. The researcher employed a mixed methods research design. The researcher performed a historical review of policies and events that led to the overcrowding of prisons and the criminalization of certain substances. Semistructured interviews were conducted with 10 individuals involved with inmate horticulture programs. Elements included in the study are the variation between programs and their perceived efficacy, challenges, and barriers.

Findings. Research findings revealed inmate horticulture programs fall into different areas of focus; innovative programs have blended components to provide integrated services. Five primary archetypes were identified: rehabilitative/therapeutic, punitive/labor, vocational, cost savings, and sustainability. Collaboration was crucial in framing the conversation, determining the skillsets of those involved, and the best way to leverage resources. Challenges to diffusing therapeutic inmate horticulture programs stem from social and political inflexibility.

Conclusions and Recommendations. The social construction of an issue or population impacts the political response, framing of issues, and type of media attention received. The amount of public demand to address the policy issue and federal government involvement influence the adoption and diffusion of innovations. The community benefits from horticulture programs, because former inmates are less likely to commit crimes or victimize people if they have been exposed to rehabilitative programs that prepare them for job opportunities upon release. Well-rounded programs give participants an understanding of food justice, horticulture, leadership, restoration, and healing and access to wraparound services.

Abstract:
In a wide range of counselling situations, including those involving offenders, researchers have bemoaned the lack of consensus about outcome. Some researchers have argued that a lack of consensus is due to the fact that the different sources retain unique points of view, which can never be amalgamated into a common outcome. The current paper argues that, while sources will have their own unique perspective, it is possible to develop a meaningful consensus, if it is done very carefully. The factors which need to be taken into consideration are: measuring different outcomes; the different interpretation of the question by each source; and bias. An important outcome in correctional settings is an offender's current level of criminality, or likelihood of reoffending. It was hypothesised that the 12 Probation and Parole Officers' predictions about the likelihood of recidivism of 368 offenders would correlate with fresh charges recorded within 12 months by the Magistrates Court. This hypothesis was supported. It was also hypothesised that the Level of Service Inventory - Revised (LSI-R) would also correlate with fresh charges and that the former correlation would be different to the latter. While the LSI-R did correlate significantly with fresh charges, the predictions of the Probation and Parole Officers were not significantly different. The use of correlation coefficients to assess predictive validity has been criticised as they are affected by base rates of offending and selection ratios of offenders to high and low risk categories. However when a more appropriate statistical tool, the area under the Receiver Operating Characteristic curve (ROC) was employed, the results were not substantially different. The predictive abilities of offenders was also tested against the same criterion and Intersource Agreement on the Prediction Recidivism were found sorely wanting, failing to correlate with fresh charges or any of the other predictive measures. It is argued that the offenders failed to predict accurately because of bias and/or poor ability to predict their own behaviour. The ability of the Probation and Parole Officers to predict reoffending to a much greater level than usually recorded in the criminological literature was ascribed to the higher level of information about their own predictive abilities, through a natural feedback mechanism which does not usually apply to professionals making clinical predictions about recidivism, and to training in predictors of reoffending which they received when they were trained in the administration of the LSI-R. It was also found that the ability of the LSI-R to predict recidivism was improved by incorporating offender age through linear regression. Suggestions were made for improving consensus among sources in counselling outcome studies. In particular, it was noted that sources do not necessarily interpret the question in the manner the researcher desires and it may be necessary to test the subjects' ability to distinguish between similar questions when this distinction is important.

Abstract:
This study was conducted within two forensic settings, the high security correctional facility Saltviksanstalten, and the forensic psychiatric institution Karsudden hospital. 66 staff members from Saltvik and 39 from Karsudden participated by answering a questionnaire about threat and physical violence perpetrated towards them by inmates/patients. The aim of the present study was to analyze and compare the prevalence of threat and physical violence and related factors perpetrated by inmates/patient towards staff within these two forensic settings with the objectives to compare and analyse the prevalence, characteristics, situations and consequences of the threat and physical violence. The results showed that a higher percentage of participants were exposed to threats and physical violence within the forensic psychiatric setting. As regards to the intentions behind the threats and physical violence, inmates within high security correctional facilities was to a higher degree instrumental whereas patients within the forensic psychiatry showed a higher degree of reactive intentions. The conclusion is that victimization in the form of threat and physical violence is comprehensive, especially within the forensic psychiatry. Due to that victimization increases both the risk of revictimization, and have a number of negative personal- and societal consequences, this is an issue that needs to be highlighted in order to improve both the work environment and the mental health for the staff.

Abstract:
This study had a two-fold purpose. The first purpose was to compare the rankings of a set of knowledge/skills statements as reported by teachers of students with emotional behavioral disorders and teachers in juvenile correctional special education settings. A survey instrument designed to measure the importance, proficiency, and frequency of use of clusters of knowledge/skills statements was administered to 123 teachers in juvenile correctional special education settings in state institutions. Mann Whitney U analyses were calculated to compare the mean rankings of the two groups of teachers. The findings indicated that teachers in juvenile correctional special education settings and teachers of students with emotional and behavioral disorders were very similar as to which knowledge/skills clusters were important to their job performance, which clusters they were most proficient at using, and which clusters they utilized most frequently. The second purpose was to compare the teachers in juvenile correctional special education settings and to determine whether their mean rankings of the knowledge/skills clusters varied when analyzed by differing categories of age, type of certification held, years of teaching experience, and level of the teachers' education. Analysis of variance revealed no significant difference in the mean rankings in any of the comparison groups. Therefore teacher age, level of education, type of certification held, or years of teaching experience yielded no significant differences on the mean rankings of the knowledge/skills clusters.

Full text
Abstract:
Because the contact bearings of spiral bevel and hypoid gears are highly sensitive to tooth flank geometry, it is desirable to reduce the flank deviations caused by machine errors and heat treatment deformation. Several methods already proposed for flank correction are based on the cutter parameters, machine settings, and kinematical flank motion parameters of a cradle-type universal generator, which are modulated according to the measured flank topographic deviations. However, because of the recently developed six-axis Cartesian-type computer numerical control (CNC) hypoid generator, both face-milling and face-hobbing cutting methods can be implemented on the same machine using a corresponding cutter head and NC code. Nevertheless, the machine settings and flank corrections of most commercial Cartesian-type machines are still translated from the virtual cradle-type universal hypoid generator. In contrast, this paper proposes a flank-correction methodology derived directly from the six-axis Cartesian-type CNC hypoid generator in which high-order correction is easily achieved through direct control of the CNC axis motion. The validity of this flank correction method is demonstrated using a numerical example of Oerlikon Spirac face-hobbing hypoid gears made by the proposed Cartesian-type CNC machine.

Abstract:
Face-hobbing is a continuous generating process employed in manufacturing spiral bevel and hypoid gears. Due to machining dynamics and tolerances of machine tools, exact tooth surface geometry may not be obtained from the machining process using theoretical machine tool settings. Repeatable tooth surface geometric errors may be observed. The tooth surface errors will cause unfavorable displacement of tooth contact and increased transmission errors, resulting in noisy operation and premature failure due to edge contact and highly concentrated stresses. In order to eliminate the tooth surface errors and ensure precision products, a corrective machine setting technique is employed to modify the theoretical machine tool settings, compensating for the surface errors. This paper describes a method of correcting tooth surface errors for spiral bevel and hypoid gears generated by face-hobbing process using computer numerically controlled (CNC) hypoid gear generators. Polynomial representation of the universal motions of machine tool settings is considered. The corrective universal motion coefficients are determined through an optimization process with the target of minimization of the tooth surface errors. The sensitivity of the changes of tooth surface geometry to the changes of universal motion coefficients is investigated. A numerical example of a face-hobbed hypoid pinion is presented.

Abstract:
The increasing demand for low noise and high strength leads to higher quality requirements in manufacturing spiral bevel and hypoid gears. Due to heat treatment distortions, machine tolerances, variation of cutting forces and other unpredictable factors, the real tooth flank form geometry may deviate from the theoretical or master target geometry. This will cause unfavorable displacement of tooth contact and increased transmission errors, resulting in noisy operation and premature failure due to edge contact and highly concentrated stresses. In the hypoid gear development process, a corrective machine setting technique is usually employed to modify the machine settings, compensating for the tooth flank form errors. Existing published works described the corrective machine setting technique based on the use of mechanical hypoid gear generators, and the second order approximation of error surfaces. Today, Computer Numerically Controlled (CNC) hypoid gear generators have been widely employed by the gear industry. The Universal Motion Concept (UMC) has been implemented on most CNC hypoid generators, providing additional freedoms for the corrections of tooth flank form errors. Higher order components of the error surfaces may be corrected by using the higher order universal motions. This paper describes a new method of tooth flank form error correction utilizing the universal motions for spiral bevel and hypoid gears produced by the face-milling process. The sensitivity of the changes of tooth flank form geometry to the changes of universal motion coefficients is investigated. The corrective universal motion coefficients are determined through an optimization process with the target of minimization of the tooth flank form errors. A numerical example of a face-mill completing process is presented. The developed new approach has been implemented with computer software. The new approach can also be applied to the face-hobbing process.

Abstract:
This paper outlines a systematic methodology for finding the machine setting corrections required to obtain a predesigned ease-off surface in spiral bevel and hypoid gear teeth. The problem is given a nonlinear least squares formulation which, however, is highly prone to numerical instabilities. The Levenberg–Marquardt algorithm with a trust region strategy turned out to be quite effective and robust to obtain feasible solutions. The proposed method was tested on lengthwise crowning, profile crowning and spiral angle correction. In all cases, the goal was achieved with very high accuracy, in a few iterations and, remarkably, with different sets of machine parameters.

Abstract:
In this paper we set out to investigate the performances of some of the algorithms proposed in the gear literature for identifying the machine-settings required to obtain predesigned gear tooth surface topographies, or needed to compensate for flank form deviations of real teeth. For the ease of comparison, the problem is formulated as a nonlinear least-squares minimization, and the most widely employed algorithms are derived as particular cases. The algorithms included in the analysis are: (i) one-step methods; (ii) iterative methods; (iii) iterative methods with step control. The performance index is devised in their ability of returning practical solutions in the presence of: (i) strong model nonlinearities, (ii) ill-conditioning of the sensitivity matrix, (iii) demanding topographic shapes purposely selected. Instrumental here is an original classification of topographic modifications as either “simple” or “complex”, based on the SVD analysis of the sensitivity matrix. On the basis of the numerical tests documented, iterative techniques with step control seem the most convenient, due to reliability and robustness of the solutions produced. The generation process here considered is face-milling of hypoid gears, even though the methodology is general enough to cope with any gear cutting method requiring only some minor technical changes.

Abstract:
Abstract The authors propose an approach that uses coordinate measurements of the real surface to: (i) determine the real applied machine-tool settings, (ii) determine the deviations of the real surface from the theoretical one, (iii) minimize the deviations by correction of the machine-tool settings, and (iv) represent the real surface analytically in the same Gaussian coordinates as the theoretical one.

Abstract:
Many modern power plants feature gas turbines with advanced control systems that allow a greater level of performance enhancements, over a broader range of the combined-cycle plant’s operating environment, compared to conventional systems. Control system advancements tend to outpace a plant’s construction and commissioning timescale. Often, the control algorithms and settings in place at the final guarantee performance test will differ significantly from those envisioned during the contract agreement phase. As such, the gas turbine’s actual performance response to changes in boundary conditions, such as air temperature and air humidity, will be considerably different than the response illustrated on the initial correction curves. For the sake of technical accuracy, the performance correction curves should be updated to reflect the as-built, as-left behavior of the plant. By providing the most technically accurate curves, the needs of the new plant performance test are satisfied. Also, plant operators receive an accurate means to trend performance over time. The performance correction curves are intended to provide the most technically accurate assurance that the corrected test results are independent of boundary conditions that persist during the performance test. Therefore, after the gas turbine control algorithms and/or settings have been adjusted, the performance correction curves — whether specific to gas turbines or overall combined-cycle plants — should be updated to reflect any change in turbine response. This best practice maintains the highest level of technical accuracy. Failure to employ the available advanced gas turbine control system upgrades can limit the plant performance over the ambient operating regime. Failure to make a corresponding update to the correction curves can cause additional inaccuracy in the performance test’s corrected results. This paper presents a high-level discussion of GE’s recent gas turbine control system advancements, and emphasizes the need to update performance correction curves based on their impact.
