Teaching To Trouble: Critical Book Reviews as Pedagogy to Interrogate Education Praxis

How might education professors disrupt traditional curriculum and teaching practices that teach future teachers to label, segregate, and marginalize students with disabilities? The Disability Studies in Education (DSE) approach grounds practice on the perspectives of people with disabilities and challenges practices that isolate and de-humanize individuals. The pedagogy for eliciting critical book reviews using a DSE perspective is described. DSE is an interdisciplinary field which unites critical inquiry, political advocacy, and approaches from the arts, humanities, and humanistic/post-humanistic social sciences to improve the lives of people with disabilities based on their expressed wishes (Gabel, 2005). A disabilities studies in education (DSE) theoretical framework relies on the experiences and perspectives of people with disabilities to challenge actions that maintain the status quo (Danforth & Gabel, 2006). The purpose of this paper is to document the pedagogy of writing book reviews that use a DSE perspective to critique the work. Theoretical Framework The instructional pedagogy is based on Paulo Freire's (1985) notions of critiquing and was co-created over the course of 2 semesters by one professor and 13 graduate students (6 in 2009 and 7 in 2010) and the author. Freire (1998) posited that critiquing the reading “before anything else, [is] a critical, creative, recreating activity" (p. 18). It is naturally occurring by virtue of the curiosity of the one who is studying. Studying what other people have written sets us up in a special way so that we are "Reading the word [which] enables us to read a previous reading of the world" (Freire, 1998, p. 18). That world may no longer be pertinent, but the word has captured it for us to read and ponder. A Brief History of DSE According to Danforth and Gabel (2006), a DSE approach relies on intellectual and practical tools as well as forms of thought and action that (a) nurture a deeper awareness among educators about disability rights, (b) lead to more inclusive participation, and (c) reveal the uniqueness and importance of disability identity. DSE is a relatively new field of study (Connor, Gabel, & Peters, 2006), beginning with the influences of the 1960s-1970s. The field was spurred into action during the Civil Rights era in the United States and the worldwide Independent Living movement. Methods In this section, we describe the participants, the elements of the critical book review, the criteria for a critical book review using DSE principles, and the instructional methods or interactions that elicited the reviews. We refer to key resources that support the pedagogy.
Validity and Reliability of the Preventing Hookah Smoking (PHS) Questionnaire in Adolescents based on the Protection Motivation Theory

Background: Considering the importance of preventing smoking hookah in adolescents and the lack of a standard questionnaire in this field, this study aimed to develop and validate a Persian Preventing Hookah Smoking (PHS) Questionnaire in adolescents based on the Protection Motivation Theory. Materials and Methods: After conducting focus groups discussion, reviewing the literature and scientific resources, an initial self-administered questionnaire including 68 questions was designed and then validated. For face validity, the questionnaires were evaluated by 10 experts considering difficulty, inappropriateness, and ambiguity of the phrases. Both quality and quantity methods were used to evaluate the content validity. The content validity ratio (CVR) and the content validity index (CVI) were determined by a group of experts (10 people). Its internal consistency was estimated and its reliability was determined by the test-retest method. Confirmatory Factor Analysis (CFA) was done using Amos 21.0. Results: From 68 questions in the initial questionnaire, eventually 64 questions remained in the final questionnaire. The CVR value for most questions, except for 3 questions, was above 0.79 and the CVI value of all questions was above 0.79. The Cronbach’s alpha coefficient was 0.79-0.91 and the test-retest coefficient was 0.81-0.91. The results of CFA showed the following values, Chi-square (x2): 1254.712, degree of freedom (df): 3.456, adjusted goodness of fit index (AGFI): 0.964, the root mean square error of approximation (RMSEA): 0.072 which indicates the appropriateness of the tool among Iranian adolescents. Conclusion: The results of this study showed that this Persian questionnaire about preventing hookah smoking in adolescents based on the Protection Motivation Theory has a good validity and reliability and can be used in investigating about prevention of hookah smoking in adolescents.
End-to-end process of hollow spacecraft structures with high frequency and low mass obtained with in-house structural optimization tool and additive manufacturing

In the space sector the most decisive elements are: mass reduction, cost saving and minimum lead time; here, structural optimization and additive layer manufacturing (ALM) fit best. The design must be driven by stiffness, because an important requirement for spacecraft (S/C) structures is to reduce the dynamic coupling between the S/C and the launch vehicle. The objective is to create an end-to-end process, from the input given by the customer to the manufacturing of an aluminum part as light as possible but at the same time considerably stiffer while taking the full advantage of the design flexibility given by ALM. To design and optimize the parts, a specialized inhouse tool was used, guaranteeing a load-sufficient material distribution. Using topological optimization, the iterations between the design and the stress departments were diminished, thus greatly reducing the lead time. In order to improve and lighten the obtained structure a design with internal cavities and hollow beams was considered. This implied developing of a procedure for powder evacuation through iterations with the manufacturer while optimizing the design for ALM. The resulted part can be then manufactured via ALM with no need of further design adjustments. To achieve a high-quality part with maximum efficiency, it is essential to have a loop between the design team and the manufacturer. Topological optimization and ALM work hand in hand if used properly. The team achieved a more efficient structure using topology optimization and ALM, than using conventional design and manufacturing methods.
A Unified Directional Spectrum for Long and Short Wind-Driven Waves

Review of several recent ocean surface wave models finds that while comprehensive in many regards, these spectral models do not satisfy certain additional, but fundamental, criteria. We propose that these criteria include the ability to properly describe diverse fetch conditions and to provide agreement with in situ observations of Cox and Munk [1954] and Jahne and Riemer [1990] and Hara et al. [1994] data in the high-wavenumber regime. Moreover, we find numerous analytically undesirable aspects such as discontinuities across wavenumber limits, nonphysical tuning or adjustment parameters, and noncentrosymmetric directional spreading functions. This paper describes a two-dimensional wavenumber spectrum valid over all wavenumbers and analytically amenable to usage in electromagnetic models. The two regime model is formulated based on the Joint North Sea Wave Project (JONSWAP) in the long-wave regime and on the work of Phillips [1985] and Kitaigorodskii [1973] at the high wavenumbers. The omnidirectional and wind-dependent spectrum is constructed to agree with past and recent observations including the criteria mentioned above. The key feature of this model is the similarity of description for the high- and low-wavenumber regimes; both forms are posed to stress that the air-sea interaction process of friction between wind and waves (i.e., generalized wave age, u/c) is occurring at all wavelengths simultaneously. This wave age parameterization is the unifying feature of the spectrum. The spectrum's directional spreading function is symmetric about the wind direction and has both wavenumber and wind speed dependence. A ratio method is described that enables comparison of this spreading function with previous noncentrosymmetric forms. Radar data are purposefully excluded from this spectral development. Finally, a test of the spectrum is made by deriving roughness length using the boundary layer model of Kitaigorodskii. Our inference of drag coefficient versus wind speed and wave age shows encouraging agreement with Humidity Exchange Over the Sea (HEXOS) campaign results.
On the use of ID-Based Cryptography for the definition of new EAP authentication methods

We propose in this paper, two ID-Based authentication methods for the Extensible Authentication Protocol (EAP), as an alternative to methods relying on Public Key Infrastructure (PKI), to provide nodes with private and public keys. ID-Based Cryptography (IBC) proposes to derive the public key from the node's identity directly. As such, there is no need for deployment of a Certification Authority (CA) and the burdensome management of certificates is removed. IBC relies on a Private Key Generator (PKG) for the computation of stations private keys. Our first presented authentication method corresponds to a situation where the PKG is trustful. As such, the PKG generates the private keys of all the network stations. However, our second contribution presents an authentication method which is resistant to the Key Escrow Attack. That is, we make each station generate its own ID-Based private key. In addition, results from implementation tests are given and prove how efficient IBC might be for use in wireless networks.
Reliability and Validity of Child Posttraumatic Stress-Revised Instrument in Malay Language among Malaysian Adolescents

Background: Most PTSD screening tools for children and adolescents have been validated in Western contexts which is not necessarily generalizable to non-western cultures. Therefore, the objective of this cross-sectional study was to determine the psychometric properties of the Child Posttraumatic Stress Disorder Reaction Index (CPTS-RI) within a Malaysian population. Methods: Eighty-five adolescents aged 13- to 14-years-old completed the CPTS-RI, Harvard Trauma Questionnaire (HTQ) and Hopkins Symptom Checklist scale (HSCL). Results: Results showed a good internal consistency for the overall scale (α =.92), for the subscale -re-experience, avoidance and arousal subscales (α = .89, α = .73, α = .56 respectively) and for different gender groups and ethnicity. CPTS-RI demonstrated good construct and divergent validity, and showed good concurrent validity with the use of HTQ and HSCL as the criterion measure. Conclusion: Findings suggest that CPTS-RI is a valid and reliable instrument to assess PTSD symptoms among Malaysian adolescents. Please click PDF below to download the full paper.
AN ASSESSMENT OF ORGANISATIONAL JUSTICE PERCEPTIONS ACROSS THREE GENERATIONAL COHORTS

Despite several reviews of generational differences across cohorts regarding their career stages in organisations, relatively few empirical investigations have been conducted to understand these cohorts’s behaviour and perceptions. Hence there is paucity of studies that explored the generational differences on the construct organisational justice across generational cohorts. The objective of this study was to assess the differences across three generational cohorts (Millennials, Generation X, and Baby Boomers) on dimensions of the organisational justice construct using the Organisational Justice Measurement Instrument (OJMI). Data was collected through the administration of OJMI to a random sample size of organisational employees (n=289). Descriptive statistics and analysis of variance were conducted to interpret the data. These findings provide evidence that differences do exist across cohorts on dimensions of organisational justice, and some differences may be a result of respondents’ different perception of their organisation’s practices and processes. In terms of contributions and practical implications, insight gained from the findings may be used in proposing organisational development interventions to manage multigenerational employees as well as to conduct future research.
Numerical simulation of the effects of diaphragm length on potential flow around a circular cylinder with rear diaphragm

Received: 1 October 2017 Accepted: 22 February 2018 To disclose the flow field features around a circular cylinder with rear diaphragm, this paper numerically simulates the effects of diaphragm length on the potential flow around such a circular cylinder, using the characteristic-based operator splitting (CBOP) method based on multi-step format (MSF). Through the simulation, the author obtained the flow field velocities, mean drag coefficient, lift coefficient and Strouhal number, and analysed the variation laws of the flow field features. The research shows that the addition of the rear transverse diaphragm can effectively suppress the vortex shedding in the wake region, reduce the pressure difference between the upper and lower surfaces of the circular cylinder, and greatly improve the flow around the circular cylinder. When the diagram length was sufficiently long, the vorticity of the upper and lower shear layers was completely dissipated during the backward movement along the transverse diaphragm, eliminating the occurrence of vortex shedding. The simulated laws of the flow velocities and flow field eigenvalues were consistent with the results of the previous studies. The research findings provide a valuable reference for similar studies in future.
Perceptions of a management development intervention in the South African Police Service.

The focus of this project is the South African Police Service. The study looked at whether what is happening in a police station could be associated with a management development intervention -Police Station Management Programme attended by Station Commissioner and Senior Managers recently. Using the qualitative approach mainly the case study, the study looked at the perception of the programme at three police stations. Also, the South African Police Service is considered in historical context of South Africa and mainly the post 1994 period Various and somewhat contradictory themes emerged in the responses. Firstly, the report highlights that the process leading to participating in the programme by the various police officers was top-down. Yet after training the police Station Commissioners and Unit Managers embraced concepts such as learning organisation, community policing and human rights all very democratic issues in some cases within the contexts of scarce resources. Although this was a small-scale study, several implications related to the development and management of development programmes could be highlighted. First, there is a need to look at and conduct needs analysis of organisations and the staff before designing the programmes. Secondly, after such analysis, there is a need to offer challenging responsibilities to personnel consistent with the newly acquired skills, knowledge and attitudes. I declare that this research report is my own, unaided work. It is submitted in partial fulfilment of the requirements of the degree of Master of Management in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination in any other University. day of Febmary 2000.
Influence of Family on Saudi Arabian Emergency Medical Services Students

Objective: To identify influences on learning for Saudi male students studying Emergency Medical Services at a college in Riyadh, Saudi Arabia. Previous research on influences on student learning in the Kingdom of Saudi Arabia focused on the historical development of education in Saudi Arabia, English language development, and intrinsic motivations of students and excluded a focus on students studying Emergency Medical Services. Methods: Exploratory sequential mixed-methods study was deployed. Results: Family support was an exceptionally strong predictor of student confidence in both skills and post-graduate EMS employment. Concepts involving application, memorization, motivation, and English language did not present as statically significant. The discovery of the strong influences that a family can have on Saudi EMS student’s confidence is noteworthy, as this was not previously discovered in the literature. Conclusion: This discovery holds practical implications for EMS education and training programs as emphasizes the importance of developing practical ways to include a student’s family as a source of support in ensuring student success and confidence.
Influence of NLTE calculations on the hydrogen lines in chromospheric models

We present extensive NLTE calculations for a semi-empirical solar 1D chromosphere model based on the VAL C model. We report on a significant influence of nitrogen, oxygen, and sulfur on the emergent hydrogen emission with respect to LTE vs. NLTE calculations for these elements. Moreover, we present a model spectrum with 20 light and iron group elements computed in NLTE. We compare this to an observed solar spectrum and to a photospheric model spectrum. We find that the agreement for this model with the data is less good than the original VAL C model especially in the UV. This may imply the need of changes in the chromospheric temperature structure or may point to general problems of static 1D chromospheric models.
A Formal Model for Legacy System Understanding

Migration of legacy system is not a single step activity but a process that comprises of several phases of which Legacy System Understanding (LSU) is the first step. The intent of this work is to carry out a detailed study on the Legacy System Understanding in terms of Techniques and Tools used and to identify the potential gaps in them. The understanding of the legacy system has to be at the perspective of system level rather than the code level which has a narrow perspective, because the migration at code level may have a cascading impact to different aspects of the Legacy System. These findings have enabled us to formulate a process for building up an artefact repository and artefact dependency repository. These repositories along with the legacy system have aided us in understanding the legacy system in a comprehensive manner in terms of migrating artefacts in the context of migration of legacy systems. A formal mathematical model for representing the status of LSU and application of the same on a case study has been presented.
A Study of Teachers' Perception of Schools' Organizational Health in Osun State

This study examined the teachers’ perceptions of school organizational health (i.e. resource support, job satisfaction among staff, morale boosts, institutional integrity and initiating structure). Descriptive survey design was used for the study. The sample was composed of 330 secondary school teachers randomly selected from 283, 826 secondary school teachers in Osun State. Data collected was subjected to t-test analysis. It was found that that there is higher homogeneity within the group of male and female secondary school teachers and public secondary school teachers have a higher perception than their private counterpart. In conclusion, governments at various levels who are the proprietor of public schools have the best of teacher who are committed to having good organizational health in the schools. Thus, with little motivation and encouragement this commitment to good organizational health could be transformed into commitment to work and thus, leading to better academic performance of students in the public schools.
How a Minimum Time Step and Formation of Initial Causal Structure in Space-Time May Void the Penrose Singularity Theorem, as in Hawkings and Ellis’s 1973 Write-Ups

Using a root finder procedure to obtain we use an inflaton value due to use of a scale factor if we furthermore use . From use of the inflaton, we initiate a procedure for a minimum scale factor, which would entail the , for a sufficiently well placed frequency ω. If the Non Linear Electrodynamics procedure of Camara et al. of General relativity was used, plus the modified Heisenberg Uncertainty principle, of Beckwith, and others, i.e . we come due to a sufficiently high frequency a case for which implies a violation of the Penrose singularity theorem, i.e . this is in lieu of . If this is not true, i.e. that the initial , then we will likely avoid for reasons brought up in this manuscript.
The use of Classification and Regression Tree to predict 15-year survival in community-dwelling older people

Previous research has identified various risk factors for mortality in older people. The aim of this paper was to use Classification and Regression Tree to predict 15-year survival in community-dwelling older people. Data were obtained from a United Kingdom representative sample of 1042 community-dwelling people aged 65 and over. Outcome was time from 1985 interview to death or censorship on February 29, 2000. Classification and Regression Tree is a non-parametric technique widely used in medical domain classification. We applied CART to the set of risk-factors identified in a previous research. The selected CART model is based on age, dose of drug prescribed and handgrip measures. It predicts survival with a sensitivity rate of 76.3% and a specificity rate of 66.3%. The selection of variables are consistent with previous research. Finally, we observed the range of risk factors and their combination associated with increased and decreased mortality.
Sowing speed in no tillage system on early development of maize crop

Sowing is a fundamental stage in crops’ cultivation process. If performed improperly, it can compromise the entire crop development. Seeding speed stands out as a key factor which can affect seeding quality. The objective of this study was to assess the effects of variation of working speed in maize initial establishment and in direct seeding’s’ quality parameters. The experiment was carried out in the municipality of Tangara da Serra – MT. Four seeding speeds were used V1 equal 1.11 (4.0), V2 equal 1.39 (5.0), V3 equal 1.67 (6.0) and V4 equal 1.94 m s -1 (7.0 km h -1 ). The assessed parameters were emergence speed index, emergence rate, seed deposition depth, plant spacing, and initial plant population. No interference of seeding speed variation was observed in seed deposition depth, emergence speed index and initial plant population. However, seeding speed influenced in plant spacing, in which speed increase was proportional to plant spacing increase.
Creative Destruction and Employee Well-Being

We examine the effects of establishment- and industry-level labor market turnover on employees’ job satisfaction and perceived job insecurity. Our linked employer-employee panel data contain both information on employees’ subjective well-being and register-based information on job and worker flows. The results show that job destruction and worker outflow measures reduce job satisfaction and, especially, perceived security. These effects are much weaker when the individual-specific fixed effects are taken into account. The evidence also reveals that the establishment-level job and worker flows do not translate into higher wages. These findings speak against the existence of compensating wage differentials for job uncertainty.
