There appears to be no empirical-based method in the literature for estimating if an engineering change proposal (ECP) will occur or the dollar amount incurred. This paper aims to present an empirically based approach to address this shortfall.

Using the cost assessment data enterprise database, 533 contracts were randomly selected via a stratified sampling plan to build two regression models: one to predict the likelihood of a contract experiencing an ECP and the other to determine the expected median per cent increase in baseline contract cost if an ECP was likely. Both models adopted a stepwise approach. A validation set was placed aside prior to any model building.

Not every contract incurs an ECP; approximately 80 per cent of the contracts in the database did not have an ECP. The likelihood of an ECP and the additional amount incurred appears to be statistically independent of acquisition phase, branch of service, commodity, contract type or any other factor except for the basic contract amount and the number of contract line item numbers; both of these later variables equally affected the contract percentage increase because of an ECP. The combined model overall bested current anecdotal approaches to ECP withhold.

This paper both serves as a published reference point for ECP withholds in the archival forum and presents an empirically based method for determining per cent ECP withhold to use.

This paper examines the relationship between a prime contractor's financial health and its mergers and acquisitions (M&A) spending in the defense industry. It aims to provide models that give the United States Department of Defense (DoD) indications of future M&A activity, informing decision-makers and contributing to ensuring competitive markets that benefit the consumer.

The study uses panel data regression models on 40 companies between 1985 and 2021. The company's financial health is assessed using industry-standard financial ratios (i.e. measures of profitability, efficiency, solvency and liquidity) while controlling for economic factors such as national productivity, defense budgets and firm size.

The results show a significant relationship between efficiency and M&A spending, indicating that companies with lower efficiency tend to spend more on M&As. However, there was no significant relationship between M&A spending and a company's profitability or solvency. These results were consistent with previous research and the study's hypotheses for profitability and solvency. However, the effect of liquidity was the opposite of the expected result, possibly due to the defense industry's different view on liquidity compared to previous research.

The paper provides insights into the relationship between a prime contractor's financial health and its M&A spending, a topic with limited research. The findings can inform policymakers and regulators on the industrial base's future M&A activity, ensuring competitive markets that benefit the consumer.

The introduction of “should cost” in 2011 required all Major Defense Acquisition Programs (MDAP) to create efficiencies and improvements to reduce a program’s “will-cost” estimate. Realistic “will-cost” estimates are a necessary condition for the “should cost” analysis to be effectively implemented. Owing to the inherent difficulties in establishing a program’s will-cost estimate, this paper aims to propose a new model to infuse realism into this estimate.

Using historical data from 73 Departments of Defense programs as recorded in the selected acquisition reports (SARs), the analysis uses mixed stepwise regression to predict a program’s cost from Milestone B (MS B) to initial operational capability (IOC).

The presented model explains 83 per cent of the variation in the program acquisition cost. Significant predictor variables include: projected duration (months from MS B to IOC); the amount of research development test and evaluation (RDT&E) funding spent at the start of MS B; whether the program is considered a fixed-wing aircraft; whether a program is considered an electronic system program; whether a program is considered ACAT I at MS B; and the program size relative to the total program’s projected acquisition costs at MS B.

The model supports the “will-cost and should-cost” requirement levied in 2011 by providing an objective and defensible cost for what a program should actually cost based on what has been achieved in the past. A quality will-cost estimate provides a starting point for program managers to examine processes and find efficiencies that lead to reduced program costs.

The Weapon Systems Acquisition Reform Act (WSARA) was enacted in 2009 to improve Department of Defense public procurement processes and limit cost overruns in major acquisition programs.

Seven years later, the authors investigate the effects of WSARA on cost overruns for major Air Force acquisition programs and then conduct an exploratory case study specifically targeting WSARA impacts on the Operations and Support phase of a program’s life cycle.

The authors find that while there are some positive impacts on cost overruns in limited areas, the majority of the models demonstrate either no statistically significant effect from WSARA or an increase in cost overruns post implementation.

These findings are consistent with much of the literature on the historical ineffectiveness of previous acquisition reforms to ameliorate cost overruns.

Since the 1950s, the closet has been the chief metaphor for conceptualizing the experience of sexual minorities. Social change over the last four decades has begun to dismantle some of the social structures that historically policed heteronormativity and forced queer people to manage information about their sexuality in everyday life. Although scholars argue that these changes make it possible for some sexual minorities to live “beyond the closet” (Seidman, 2002), evidence shows the dynamics of the closet persist in organizations. Drawing on a case study of theme park entertainment workers, whose jobs exist at the nexus of structural conditions that research anticipates would end heterosexual domination, I find that what initially appears to be a post-closeted workplace is, in fact, a new iteration: the walk-in closet. More expansive than the corporate or gay-friendly closets, the walk-in closet provides some sexual minorities with a space to disclose their identities, seemingly without cost. Yet the fundamental dynamics of the closet – the subordination of homosexuality to heterosexuality and the continued need for LGB workers to manage information about their sexuality at work – persist through a set of boundaries that contain gayness to organizationally desired places.

Worldwide efforts to identify individuals infected with the hepatitis C virus (HCV) focus almost exclusively on community healthcare systems, thereby failing to reach high-risk populations and those with poor access to primary care. In the USA, community-based HCV testing policies and guidelines overlook correctional facilities, where HCV rates are believed to be as high as 40 percent. This is a missed opportunity: more than ten million Americans move through correctional facilities each year. Herein, the purpose of this paper is to examine HCV testing practices in the US correctional system, California and describe how universal opt-out HCV testing could expand early HCV detection, improve public health in correctional facilities and communities, and prove cost-effective over time.

A commentary on the value of standardizing screening programs across facilities by mandating all facilities (universal) to implement opt-out testing policies for all prisoners upon entry to the correctional facilities.

Current variability in facility-level testing programs results in inconsistent testing levels across correctional facilities, and therefore makes estimating the actual number of HCV-infected adults in the USA difficult. The authors argue that universal opt-out testing policies ensure earlier diagnosis of HCV among a population most affected by the disease and is more cost-effective than selective testing policies.

The commentary explores the current limitations of selective testing policies in correctional systems and provides recommendations and implications for public health and correctional organizations.

The purpose of this paper is to test the user acceptability (Phase 1) and effects (Phase 2) of completing sedentary work while using a seated active workstation.

In Phase 1, 45 sedentary employees completed an acceptability questionnaire immediately after performing sedentary work tasks (typing, mousing) while using the seated active workstation for 30 minutes. In Phase 2, the paper tested the differential effects of completing sedentary work tasks at two different workstations (sedentary workstation vs seated active workstation) on physiological (energy expenditure, muscle activity, heart rate, blood pressure), cognitive (learning, memory, attention) and work performance (typing and mousing ability) outcomes among 18 sedentary employees.

In Phase 1, 96 percent of participants reported they would use the seated active workstation “daily” if provided access in their office. In Phase 2, working while using the seated active workstation increased energy expenditure (p<0.001; d=3.49), heart rate (p<0.001; d=1.26), systolic blood pressure (p=0.02; d=0.79), and muscle activation of the biceps femoris (p<0.001; d=1.36) and vastus lateralis (p<0.001; d=1.88) over the sedentary workstation. No between-group differences were observed for any measures of cognitive function. Mouse point and click time was slower while using the seated active workstation (p=0.02).

These findings suggest this seated active workstation to be acceptable by users and effective for offsetting occupational sedentary time without compromising cognitive function and/or work performance.

The present study is the first to test the potential of this seated active workstation in any capacity.

The purpose of this study was to explore early help provision to children and families not reaching the Children Act (1989) child in need threshold, across all 152 English local authorities in 2017.

A freedom of information request was used, in September 2017, to obtain information regarding recorded numbers, attributes and referral reasons for Early Help cases, case categorisation, professional groups involved in this provision and models of practice.

Responses revealed there are no common protocols categorising referrals and identified needs of children and young people. Child behavioural issues were the most frequently occurring category followed by parenting issues and child emotional well-being. The numbers of children engaged by Early Help services varied with a range between Barnsley with 7.8% of children under 18 years old and Richmond on Thames with 0.33% and only exceeded children in need in a 7 out of 71 reporting authorities. Models of practice used were most commonly based on the assessment framework, which operates at all social work thresholds including child protection. The enquiry found a diverse workforce involved in Early Help and sets it within a context of local thresholds for dealing with large increases in referral rates to children’s services departments in recent years.

The study provides a unique insight into the nature and scope of Early Help provision across England. The relationship between existing thresholds of intervention in the child welfare system is underexplored in the social work literature.

The 2020 murder of George Floyd resulted in challenges to policing in the United States of America, but little is known about how police chiefs perceive them. At the same time, chiefs of police wield great influence over public perceptions of crime and disorder, the state of their profession, the laws and policies that govern the conduct of police officers and municipal public safety budgets. It is therefore critical to understand how police perceive the changes to their profession post-Floyd.

This study surveyed a randomly selected national sample of 276 municipal chiefs of police. Items probed resignations, recruitment, efforts to defund departments, community support, officer morale, suspects’ likelihood of obeying lawful orders and career risks that could inhibit proactive police work. It examined associations between perceptions and Census Bureau region, length of tenure as chief, size of police department, population served and the urban or rural designation of the jurisdiction.

Chiefs overwhelmingly reported recruiting qualified candidates had become much harder, and the present risks of proactive police work encourage inaction. Chiefs of agencies in the Northeast perceived more challenges than those in the South. Respondents with more years of experience were less likely to perceive the current situation as dire. Approximately 13.5% reported an attempt to defund their department, 56.8% of which yielded some success. Our study suggests an increase in the number and scope of challenges perceived by chiefs of police. Results vary by region and police chief years of experience.

This study provides researchers and practitioners with the perspectives of chiefs about the post-Floyd era that influence their decisions, policies and initiatives.
