The development and validation of The Inquiry Science Observation Coding Sheet

Evaluation reports increasingly document the degree of program implementation, particularly the extent to which programs adhere to prescribed steps and procedures. Many reports are cursory, however, and few, if any, fully portray the long and winding path taken when developing evaluation instruments, particularly observation instruments. In this article, we describe the development of an observational method for evaluating the degree to which K-12 inquiry science programs are implemented, including the many steps and decisions that occurred during the development, and present evidence for the reliability and validity of the data that we collected with the instrument. The article introduces a method for measuring the adherence of inquiry science implementation and gives evaluators a full picture of what they might expect when developing observation instruments for assessing the degree of program implementation.     

SOGS and CGPI: Parallel Comparison on a Diverse Population

The Northern Territory of Australia, one of the most demographically and socially diverse jurisdictions in the country, conducted its first population-based gambling and problem gambling prevalence survey in 2005. Both the South Oaks Gambling Screen (SOGS) and the Canadian Problem Gambling Index (CPGI) were administered to the same sample of respondents. Using data from this survey, the current paper presents a parallel comparison of the respective screens with particular reference to gender, region, and the socio-demographic characteristics of respondents. The respective screens produced significantly different groups of problem gamblers as measured by their association with a range of socio-demographic variables. Specifically, the large number of SOGS items related to money issues may cause selective overrepresentation among low socioeconomic groups, including Indigenous people, who exist in relatively high proportions in the Northern Territory. In addition, there existed substantial gender-based differences within screens. Identified female problem gamblers were associated with household level variables (i.e. employment status, household type and marital status), while males were associated with socio-economic variables including language, education, and income. Further research is required to validate the use of problem gambling screens within the Indigenous population and to understand the role of gender in the experience and categorisation of problem gambling.     

The Factors Influencing Saving in a Matched Savings Program: Goals,Knowledge of Payment Instruments,and Other Behavior

This paper explores the saving behavior of the group of low-income households that have participated in the Australian Saver Plus matched savings program. The paper finds that a dynamic panel model represents a good technique for modeling the savings account balances of such participants. We find that, even after controlling for the unobservable individual response to the program incentive, the saving goal and education/financial literacy variables play a positive role in encouraging saving behavior. More importantly however, we find that programs such as Saver Plus are able to modify the saving behavior of individuals to the point where their prior behavior and their inherent attitude towards saving no longer play a significant role.

Recursive and en-bloc approaches to signal extraction

In the literature on unobservable component models , three main statistical instruments have been used for signal extraction: fixed interval smoothing (FIS), which derives from Kalman's seminal work on optimal state-space filter theory in the time domain; Wiener-Kolmogorov-Whittle optimal signal extraction (OSE) theory, which is normally set in the frequency domain and dominates the field of classical statistics; and regularization , which was developed mainly by numerical analysts but is referred to as 'smoothing' in the statistical literature (such as smoothing splines, kernel smoothers and local regression). Although some minor recognition of the interrelationship between these methods can be discerned from the literature, no clear discussion of their equivalence has appeared. This paper exposes clearly the interrelationships between the three methods; highlights important properties of the smoothing filters used in signal extraction; and stresses the advantages of the FIS algorithms as a practical solution to signal extraction and smoothing problems. It also emphasizes the importance of the classical OSE theory as an analytical tool for obtaining a better understanding of the problem of signal extraction.     

A Look at the Financial-Social Performance Nexus when Quality of Management is Held Constant

This research note advances understanding of the possible link between social and financial performance by using a financial-halo- removed measure of quality of management as control variable, along with more traditional controls of size, risk, and industry. The control, quality of management, is found to be highly associated with financial performance. Corporate social performance, measured both as a single indexed variable and as treatment of separate primary stakeholders (product/customer, employees, environment, and community), produces negligible or insignificant relationships with financial performance.     

Children of the condemned: grieving the loss of a father to death row

This article explores the effects of a death sentence and execution on the children of the accused. Insight into the unique bereavement of this population is provided, while contributing to the literature on death and dying. The experience of losing a father to death row and eventual execution is compared to the wider population of children with incarcerated parents and it is determined that children of death row inmates contend with a much more complicated grief process, one that has gone largely unstudied. This article contains a brief discussion of disenfranchised grief and nonfinite loss, two theories that, we argue, shape the children's grief process. The results section of the article uses qualitative data gathered from 19 children to explore the role that nonfinite loss and disenfranchised grief share in the nature of their bereavement. Our discussion focuses on the impact of stigma and violence on the grieving process. Following a discussion of the unique challenges confronting the children of death row inmates is a discussion of the implications that their experience has for practice.     

Child Support,Father–Child Contact,and Preteens’ Involvement with Nonresidential Fathers: Racial/Ethnic Differences

This study examined how child support, frequency of contact with children, and the relationship between nonresidential parents influenced preteens’ reports of the involvement of fathers and mothers in their life. Data are from the National Longitudinal Survey of Youth 1979 (NLSY79) that has followed the children of NLSY mothers from birth into their twenties. Results showed that increases in child support and in contact with the child over time after separation are linked to a better coparental relationship when children are age 11 or 12. This better relationship between parents is, in turn, associated with greater involvement of both mothers and nonresidential fathers with their children.     

Agency,reflexivity and risk: cosmopolitan,neurotic or prudential citizen?

The purpose of this paper is to critically examine the turn to risk within sociology and to survey the relationship between structure and agency as conceived by popular strands of risk theorizing. To this end, we appraise the risk society, culture of fear and governmentality perspectives and we consider the different imaginings of the citizen constructed by each of these approaches. The paper goes on to explore what each of these visions of citizenship implies for understandings of the structure/agency dynamic as it pertains to the question of reflexivity. In order to transcend uni‐dimensional notions of citizenship and to reinvigorate sociological debates about risk, we call for conceptual analyses that are contextually rooted. Exampling the importance of knowledge contests around contemporary security threats and warnings of the deleterious effects of pre‐emptive modes of regulation that derive from the ‘risk turn’ within social science, we argue for a more nuanced embrace of reflexivity within risk theorising in order to facilitate a more dynamic critique of the images of citizenship that such theorizing promotes.     

Multiple Choice Knapsack Problem: Example of planning choice in transportation

Transportation programming, a process of selecting projects for funding given budget and other constraints, is becoming more complex as a result of new federal laws, local planning regulations, and increased public involvement. This article describes the use of an integer programming tool, Multiple Choice Knapsack Problem (MCKP), to provide optimal solutions to transportation programming problems in cases where alternative versions of projects are under consideration. In this paper, optimization methods for use in the transportation programming process are compared and then the process of building and solving the optimization problems is discussed. The concepts about the use of MCKP are presented and a real-world transportation programming example at various budget levels is provided. This article illustrates how the use of MCKP addresses the modern complexities and provides timely solutions in transportation programming practice. While the article uses transportation programming as a case study, MCKP can be useful in other fields where a similar decision among a subset of the alternatives is required.
