A Hard Day’s Night on the Underground Railroad

Grade Level(s): 11The students already have a basic understanding of the Underground Railroad when we begin this mini-unit. They will be challenged about their simple ideas of the way things worked in Indiana. An in-depth study of the Underground Railroad will also help the students understand the deep sectional conflicts that stemmed from slavery.Salem High School Salem, IN 4716

School improvement in the marketplace : the case of residential special schools

Over the past couple of decades, residential special schools in Scotland have faced fundamental changes to the way they operate. This has involved the withdrawal of state funding, a shrinkage of the sector and a situation in which schools now have to sell their services in a market economy in order to survive. This article gives a brief outline of the history and development of residential special education for children considered to be troubled or troublesome. It then draws on an evaluation of one former approved, or List D, school to describe how it managed the transition to the marketplace. Findings from the evaluation are introduced and some implications of these are discussed. It is concluded that the shift from state or local authority funding to private provision may have some advantages. However, it also raises a number of questions as to whether provision for some of society's most damaged children should be determined by market forces

System hazards in managing laboratory test requests and results in primary care: medical protection database analysis and conceptual model

Objectives To analyse a medical protection organisation's database to identify hazards related to general practice systems for ordering laboratory tests, managing test results and communicating test result outcomes to patients. To integrate these data with other published evidence sources to inform design of a systems-based conceptual model of related hazards. Design A retrospective database analysis. Setting General practices in the UK and Ireland. Participants 778 UK and Ireland general practices participating in a medical protection organisation's clinical risk self-assessment (CRSA) programme from January 2008 to December 2014. Main outcome measures Proportion of practices with system risks; categorisation of identified hazards; most frequently occurring hazards; development of a conceptual model of hazards; and potential impacts on health, well-being and organisational performance. Results CRSA visits were undertaken to 778 UK and Ireland general practices of which a range of systems hazards were recorded across the laboratory test ordering and results management systems in 647 practices (83.2%). A total of 45 discrete hazard categories were identified with a mean of 3.6 per practice (SD=1.94). The most frequently occurring hazard was the inadequate process for matching test requests and results received (n=350, 54.1%). Of the 1604 instances where hazards were recorded, the most frequent was at the ‘postanalytical test stage’ (n=702, 43.8%), followed closely by ‘communication outcomes issues’ (n=628, 39.1%). Conclusions Based on arguably the largest data set currently available on the subject matter, our study findings shed new light on the scale and nature of hazards related to test results handling systems, which can inform future efforts to research and improve the design and reliability of these systems

Everyone loves select committees these days, but have they really changed?

The Wright reforms have been widely credited with reinvigorating select committees. Stephen Bates, Mark Goodwin (University of Birmingham) and Steve McKay (University of Lincoln) take issue with this assumption. They found the reforms have made little or no difference to MP turnover and attendance, which are driven by the parliamentary cycle. When MPs are jostling for payroll vote positions and trying to keep up with constituency duties and votes in the Chamber, select committees are likely to suffer

Parliamentary select committees: are elected chairs the key to their success?

Analysis of changes to House of Commons Select Committees

Elected chairs do not seem to have brought a new kind of parliamentarian to select committees

The Wright reforms have been widely credited with revitalising Parliamentary Select Committees. However, drawing on their research, Mark Goodwin, Stephen Bates and Steve McKay question whether the reforms have improved rates of turnover, attendance or gender balance. They write that commentators and MPs should avoid complacency in assuming that the reforms are a sufficiently powerful mechanism to drive improvement

Online News in Australia: Patterns of Use and Gratification

Key findings from the first national survey of the current state of play of online news consumption in Australia indicate that (1) the Internet as a news medium has reached a mainstream status in terms of audience sizes, although its penetration is still within a higher socio-economic segment of the society; (2) many distinctive features of online news have been substantially used and appreciated; and (3) from the perspective of innovation diffusion theory, online news has a notable potential to foster further adoption in the years ahead

Open Source Analytics Solutions for Maintenance

The current paper reviews existent data mining and big data analytics open source solutions. In the area of industrial maintenance engineering, the algorithms, which are part of these solutions, have started to be studied and introduced into the domain. In addition, the interest in big data and analytics have increased in several areas because of the increased amount of data produced as well as a remarkable speed attained and its variation, i.e. the so-called 3 V’s (Volume, Velocity, and Variety). The companies and organizations have seen the need to optimize their decision-making processes with the support of data mining and big data analytics. The development of this kind of solutions might be a long process and for some companies something that is not within their reach for many reasons. It is, therefore, important to understand the characteristics of the open source solutions. Consequently, the authors use a framework to organize their findings. Thus, the framework used is called the knowledge discovery in databases (KDD) process for extracting useful knowledge from volumes of data. The authors suggest a modified KDD framework to be able to understand if the respective data mining/big data solutions are adequate and suitable to use in the domain of industrial maintenance engineering

Role of Iron, Light, and Silicate in Controlling Algal Biomass in Subantarctic Waters SE of New Zealand

Phytoplankton processes in subantarctic (SA) waters southeast of New Zealand were studied during austral autumn and spring 1997. Chlorophyll a (0.2–0.3 μg L−1) and primary production (350–650 mg C m−2 d−1) were dominated by cells μm (cyanobacteria) in both seasons. The photochemical efficiency of photosystem II (Fυ/Fm) of cells was low (0.3), indicating physiological stress. Dissolved Fe (DFe) levels in surface waters were subnanomolar, and the molecular marker flavodoxin indicated that cells were iron stressed. In contrast, Subtropical Convergence (STC) and subtropical waters had higher algal biomass/production levels, particularly in spring. In these waters, DFe levels were \u3e1 nmol kg−1, there was little evidence of Fe-stressed algal populations, and Fυ/Fm approached 0.60 at the STC. In addition to these trends, waters of SA origin were occasionally observed within the STC and north of the STC, and thus survey data were interpreted with caution. In vitro Fe enrichment incubations in SA waters resulted in a switch from flavodoxin expression to that of ferredoxin, indicating the alleviation of Fe stress. In another 6-day experiment, iron-mediated increases in chlorophyll a (in particular, increases in large diatoms) were of similar magnitude to those observed in a concurrent Si/Fe enrichment; ambient silicate levels were 4 μM. A concurrent in vitro Fe enrichment, at irradiance levels comparable to the calculated mean levels experienced by cells in situ, resulted in relatively small increases (approximately twofold) in chlorophyll a. Thus, in spring, irradiance and Fe may both control diatom growth. In contrast, during summer, as mean irradiance increases and silicate levels decrease, Fe limitation, Fe/Si colimitation, or silicate limitation may determine diatom growth

Clinical and surgical management of holocervical spinal cord ependymomas.

Background:Spinal ependymomas are rare tumors of the central nervous system, and those spanning the entire cervical spine are atypical. Here, we present two unusual cases of holocervical (C1-C7) spinal ependymomas. Case Description:Two patients, a 32-year-old female and a 24-year-old male presented with neck pain, motor, and sensory deficits. Sagittal MRI confirmed hypointense lesions on T1 and hyperintense regions on T2 spanning the entire cervical spine. These were accompanied by cystic cavities extending caudally into the thoracic spine and rostrally to the cervicomedullary junction. Both patients underwent gross total resection of these lesions and sustained excellent recoveries. Conclusion:Two holocervical cord intramedullary ependymomas were safely and effectively surgically resected without incurring significant perioperative morbidity
