Abstract

Purpose

The US Government is challenged to maintain pace as the world’s de facto provider of space object cataloging data. Augmenting capabilities with nontraditional sensors present an expeditious and low-cost improvement. However, the large tradespace and unexplored system of systems performance requirements pose a challenge to successful capitalization. This paper aims to better define and assess the utility of augmentation via a multi-disiplinary study.

Design/methodology/approach

Hypothetical telescope architectures are modeled and simulated on two separate days, then evaluated against performance measures and constraints using multi-objective optimization in a heuristic algorithm. Decision analysis and Pareto optimality identifies a set of high-performing architectures while preserving decision-maker design flexibility.

Findings

Capacity, coverage and maximum time unobserved are recommended as key performance measures. A total of 187 out of 1017 architectures were identified as top performers. A total of 29% of the sensors considered are found in over 80% of the top architectures. Additional considerations further reduce the tradespace to 19 best choices which collect an average of 49–51 observations per space object with a 595–630 min average maximum time unobserved, providing redundant coverage of the Geosynchronous Orbit belt. This represents a three-fold increase in capacity and coverage and a 2 h (16%) decrease in the maximum time unobserved compared to the baseline government-only architecture as-modeled.

Originality/value

This study validates the utility of an augmented network concept using a physics-based model and modern analytical techniques. It objectively responds to policy mandating cataloging improvements without relying solely on expert-derived point solutions.

Abstract

Although there is a growing international movement toward the use of engineered or performance‐based fire safety design, current practice is dominated by prescriptive‐based design. In prescriptive‐based fire safety design, only those requirements prescribed by appropriate building regulations, installation standards, or approved documents tend to be applied. Because these requirements typically include fire protection measures, such as fire detection and signaling systems, automatic sprinkler systems, fire compartmentation, and emergency egress systems, there is often an assumption that occupants, employees, and users of a facility will be safe should a fire occur. However, there are a variety of factors that could affect the actual fire safety of a facility that comply with the appropriate regulations. Fuel type, loading, configuration, and location can change, leading to an increase in fire risk. Occupants may not see, hear or understand fire alarm signals as fire alarm signals. Fire detection and signaling systems, fire suppression systems, or smoke management systems may not be 100 percent functional at all times. Fortunately, many of these factors can be controlled for, if they are understood and addressed, within a fire safety management plan. To assist with such planning, this paper discusses various human behavior and response issues that may affect life safety during a fire or emergency, and provides suggestions for integrating these issues into a fire safety management plan.

Abstract

Hurricane Katrina remains the “most destructive disaster in U.S. history” (Farber & Chen, 2006). The purpose of this article is to examine the public procurement practices followed by local government officials in and around New Orleans within the context of Hurricane Katrina, and define impacts of disaster on procurement processes. Original and primary data drawn from interviews with officials working in and with public procurement are used to examine the role of institutional culture and practices which encourage or constrain active, responsible behavior. We find that this behavior influences the quality, including the transparency and fairness, of purchasing responses.

Abstract

WHETHER the political pendulum is to swing in the direction of the Right or not in the coming year we do not know. Local electors are not the only key to national ones whatever politicians may argue. That there will be a move towards that direction is probable as our people tire of the monotonies of any government. Any change will not affect libraries greatly at present as the world problems are too pressing to allow any practical discussion of domestic ones. Our only fear is that “economy” may become a cry, which means, of course, the lopping of things which are educational, cultural and otherwise not money‐making and it is only too probable that public libraries and indeed other libraries might suffer from the modern equivalent of the Geddes axe which some are hopefully expecting. On the other hand the strength of the organizations which control wages from below is such that the disastrous “cuts” of the first Geddes experiment are not likely to be repeated. And on wages the whole of our financial tructure rests. Moreover libraries have now assumed the right to exist in adequate condition and to displace them may not be so easy as it was thirty years ago; but, nevertheless on vigilance our safety still depends. The conditions are not likely at present to be propitious to any real advance. The much‐desired new Library Bill is being drafted—and should be—but its hearing does not seem imminent; the chances of building new libraries are bleak, and even repairs are to some librarians a nightmare. Confronting all these conditions is the greatly increased use of libraries which is reflected in every kind of public, university, national and commercial library. This strengthens faith in the future in spite of the immediate prospect.

Abstract

Purpose

The purpose of this paper is to contribute to the comprehension of the importance of “Accessible Tourism” for the specialized travel agencies by proposing suggestions and key factors to improve the supply of accessible tourism offers.

Design/methodology/approach

The paper adopts specialized travel agencies on the accessible tourism perspective of disabled tourist flows. Also, this paper describes the circumstances, social, politic, economic consequences and key decisions that thereby Turkey would be recognized, preferring, establishing on the intention of purchased and suggested positive word of mouth among people.

Findings

According to European Commission (EU) (2013) more than half of the individuals with disabilities in the EU made approximately 170 million day trips and a similar number of overnight trips within the EU during the 12 months between mid-2012 and mid-2013. Despite the developments in tourism, lack of product/service appropriate to the travel rights of the individuals with accessibility needs is one of the obstacles should be overcome. Accessible tourism is one of the keys for the survival of the specialized travel agencies in the future. Providing appropriate product/service by targeting the individuals with accessibility needs together with a correct approach and strategy, the specialized travel agencies will be able to have a competitive advantage and continue their activities. Also this market segment will create having sustainable activity and a golden opportunity for the specialized travel agencies in the future.

Originality/value

Little research has been done on accessible tourism, future development and on the impact that disabled tourists have on tourism. The paper presents suggestions on what the specialized travel agencies should do with regards to making Turkey be preferred in the future by the individuals having accessibility needs.

This study aims to examine whether earnings autocorrelation affects the risk of an accounting restatement.

Abstract

Purpose

This study aims to examine whether earnings autocorrelation affects the risk of an accounting restatement.

Design/methodology/approach

This paper uses logistic regression and identifies restatements between 2004 and 2016. Following prior research, (Dao et al., 2012; Francis and Michas, 2013; Francis et al., 2013; Lennox and Li, 2014; Lobo and Zhao, 2013; Paterson and Valencia, 2011), this study allows time between the end of our sample period and the date that this study obtained the restatement data because it takes time for material misstatements to be identified.

Findings

Bryan et al. (2018) report a negative association between autocorrelation and audit fees, suggesting that auditors view lower autocorrelation as increasing inherent risk. This study finds that autocorrelation is negatively related to accounting restatements, implying that although auditors react to lower autocorrelation by increasing their risk assessments (Bryan et al., 2018), their risk response is not sufficient. This study finds that autocorrelation has a fairly large effect: a shift from the 75th to the 25th percentile of autocorrelation is associated with a 9.38% increase in the likelihood of a restatement.

Originality/value

This study contributes to the stream of research that investigates the determinants of restatements. Not only do this study identifies autocorrelation as a factor that contributes to restatements, but importantly, this study’s results reveal a fairly substantial effect size: a shift from the 75th to the 25th percentile of autocorrelation is associated with a 9.38% increase in the likelihood of a restatement. While Bryan et al. (2018) find that autocorrelation affects audit fees, this study links autocorrelation to a more drastic consequence: accounting restatements.

Abstract

Purpose

The aim of this paper is to highlight the practical utility of using repertory grids with sexual offenders in denial and to demonstrate through a case study how they can be used to bolster both initial assessment and psychological formulation.

Design/methodology/approach

The study uses a single case study design and applies a repertory grid methodology, which is underpinned by personal construct psychology, to make sense of the case study. The analysis predominately focuses on the structure of the repertory grid.

Findings

The case study appeared to elicit factors that were of clinical utility and which could be used as tentative hypotheses for problem formulation and also seemed to point to an adequate starting point for intervention.

Research limitations/implications

The use of the case study makes generalisation difficult and future research may benefit from more large‐scale research.

Practical implications

Rather than subscribing to fatalist notions of deniers as untreatable, the paper argues that constructive work can be done with this population and that repertory grids can be one way to initially facilitate this process.

Originality/value

Currently “total deniers” are excluded from treatment and are seen as untreatable. It is argued here that this need not be the case and it is demonstrated how repertory grids can inform initial formulation with such offenders. Repertory grids have not been used with deniers before and this is an original feature of this research.

Abstract

The Scopes Monkey Trial is a landmark court case in American history and has often been referred to as “The Trial of the Century.” It provides a curricular platform for understanding changes in American society, populace tensions with shifting social and moral views, gaps in economic prosperity, and the outcomes of urbanization. Studying this pivotal and historical trial – along with the context surrounding it – offers readers a dynamic lens to view powerful social and cultural insights at the beginning of the twentieth century. Additionally, academic freedom issues, which have a history in our nation's courts, (Patterson & Chandler, 2008) as well as current dialogue among educators (see the November/December issue of Social Education), and are at the very center of the Scopes Trial, require critical examination. Most importantly, it exemplifies the type of interdisciplinary content social studies educators should be promoting, a goal of 21st Century Teaching and Learning and Common Core Standards. In this article, we provide a brief historical context setting the stage for the Scopes Monkey Trial, a daily synopsis of significant points in the trial, a rationale for teaching the Scopes Trial, and instructional teaching resources with particular emphasis on books, DVD/media, and web-based materials.
