Explaining history to children: Otto and Marie Neurath’s work on the ‘Visual history of mankind’

This essay traces the development of Otto Neurath’s ideas that led to the publication of one of the first series of children’s books produced by the Isotype Institute in the late 1940s, the Visual History of Mankind. Described in its publicity material as ‘new in content’ and ‘new in method’, it embodied much of Otto Neurath’s thinking about visual education, and also coincided with other educational ideas in the UK in the 1930s and 1940s. It exemplified the Isotype Institute’s approach: teamwork, thinking about the needs of younger readers, clear explanation, and accessible content. Further, drawing on correspondence, notes and drawings from the Otto and Marie Neurath Isotype Collection at the University of Reading, the essay presents insights to the making of the books and the people involved, the costs of production and the influence of this on design decisions, and how the books were received by teachers and children.

Agricultural commodity markets : reference point for the real value of a currency

Using monthly time-series data 1999-2013, the paper shows that markets for agricultural commodities provide a yardstick for real purchasing power, and thus a reference point for the real value of fiat currencies. The daily need for each adult to consume about 2800 food calories is universal; data from FAO food balance sheets confirm that the world basket of food consumed daily is non-volatile in comparison to the volatility of currency exchange rates, and so the replacement cost of food consumed provides a consistent indicator of economic value. Food commodities are storable for short periods, but ultimately perishable, and this exerts continual pressure for markets to clear in the short term; moreover, food calories can be obtained from a very large range of foodstuffs, and so most households are able to use arbitrage to select a near optimal weighting of quantities purchased. The paper proposes an original method to enable a standard of value to be established, definable in physical units on the basis of actual worldwide consumption of food goods, with an illustration of the method.

Optical properties of Saharan dust aerosol and contribution from the coarse mode as measured during the Fennec 2011 aircraft campaign

New in-situ aircraft measurements of Saharan dust originating from Mali, Mauritania and Algeria taken during the Fennec 2011 aircraft campaign over a remote part of the Sahara Desert are presented. Size distributions extending to 300 μm are shown, representing measurements extending further into the coarse mode than previously published for airborne Saharan dust. A significant coarse mode was present in the size distribution measurements with effective diameter (deff) from 2.3 to 19.4 μm and coarse mode volume median diameter (dvc) from 5.8 to 45.3 μm. The mean size distribution had a larger relative proportion of coarse mode particles than previous aircraft measurements. The largest particles (with deff >12 μm, or dvc >25 μm) were only encountered within 1 km of the ground. Number concentration, mass loading and extinction coefficient showed inverse relationships to dust age since uplift. Dust particle size showed a weak exponential relationship to dust age. Two cases of freshly uplifted dust showed quite different characteristics of size distribution and number concentration. Single Scattering Albed (SSA) values at 550 nm calculated from the measured size distributions revealed high absorption ranging from 0.70 to 0.97 depending on the refractive index. SSA was found to be strongly related to deff. New instrumentation revealed that direct measurements, behind Rosemount inlets, overestimate SSA by up to 0.11 when deff is greater than 2 μm. This is caused by aircraft inlet inefficiencies and sampling losses. Previous measurements of SSA from aircraft measurements may also have been overestimates for this reason. Radiative transfer calculations indicate that the range of SSAs during Fennec 2011 can lead to underestimates in shortwave atmospheric heating rates by 2.0 to 3.0 times if the coarse mode is neglected. This will have an impact on Saharan atmospheric dynamics and circulation,which should be taken into account by numerical weather prediction and climate models.

Mått för att mäta kodkvalitet undersystemutvecklingsprocessen

Viljan att hålla en hög kvalitet på den kod som skrivs vid utveckling av system och applikationerär inte något nytt i utvecklingsvärlden. Flera större företag använder sig av olika mått för attmäta kvaliteten på koden i sina system med målet att hålla en hög driftsäkerhet.Trafikverket är en statlig myndighet som ansvarar för driften av bland annat de system somhåller igång Sveriges järnvägsnät. Eftersom systemen fyller en viktig del i att säkra driften ochse till att tågpositioner, planering av avgångar och hantering av driftstörningar fungerar dygnetrunt för hela landet anser de att det är viktigt att sträva efter att hålla en hög kvalitet påsystemen.Syftet med det här examensarbetet var att ta reda på vilka mått som kan vara möjliga attanvända under systemutvecklingsprocessen för att mäta kvaliteten på kod och hur måtten kananvändas för att öka kvaliteten på IT-lösningar. Detta för att redan på ett tidigt stadie kunnamäta kvaliteten på den kod som skrivs i både befintliga och nyutvecklade system.Studien är en fallstudie som utfördes på Trafikverket, de olika måtten som undersöktes varcode coverage, nivån på maintainability index och antalet inrapporterade incidenter för varjesystem. Mätningar utfördes på sju av Trafikverkets system som i analysen jämfördes motantalet rapporterade incidenter. Intervjuer utfördes för att ge en bild över hur arbetssättet vidutveckling kan påverka kvaliteten. Genom litteraturstudier kom det fram ett mått som inte kundeanvändas praktiskt i det här fallet men är högst intressant, detta är cyclomatic complexity somfinns som en del av maintainability index men som även separat påverkar möjligheten att skrivaenhetstest.Resultaten av studien visar att måtten är användbara för ändamålet men bör inte användassom enskilda mått för att mäta kvalitet eftersom de fyller olika funktioner. Det är viktigt attarbetssättet runt utveckling genomförs enligt en tydlig struktur och att utvecklarna både harkunskap om hur man arbetar med enhetstest och följer kodprinciper för strukturen. Tydligakopplingar mellan nivån på code coverage och inflödet av incidenter kunde ses i de undersöktasystemen där hög code coverage ger ett lägre inflöde av incidenter. Ingen korrelation mellanmaintainability index och incidenter kunde hittas.

Assessing the physical environment of older people’s residential care facilities: development of the Swedish version of the Sheffield Care Environment Assessment Matrix (S-SCEAM)

Background There is emerging evidence that the physical environment is important for health, quality of life and care, but there is a lack of valid instruments to assess health care environments. The Sheffield Care Environment Assessment Matrix (SCEAM), developed in the United Kingdom, provides a comprehensive assessment of the physical environment of residential care facilities for older people. This paper reports on the translation and adaptation of SCEAM for use in Swedish residential care facilities for older people, including information on its validity and reliability. Methods SCEAM was translated into Swedish and back-translated into English, and assessed for its relevance by experts using content validity index (CVI) together with qualitative data. After modification, the validity assessments were repeated and followed by test-retest and inter-rater reliability tests in six units within a Swedish residential care facility that varied in terms of their environmental characteristics. Results Translation and back translation identified linguistic and semantic related issues. The results of the first content validity analysis showed that more than one third of the items had item-CVI (I-CVI) values less than the critical value of 0.78.  After modifying the instrument, the second content validation analysis resulted in I-CVI scores above 0.78, the suggested criteria for excellent content validity. Test-retest reliability showed high stability (96% and 95% for two independent raters respectively), and inter-rater reliability demonstrated high levels of agreement (95% and 94% on two separate rating occasions). Kappa values were very good for test-retest (κ= 0.903 and 0.869) and inter-rater reliability (κ= 0.851 and 0.832). Conclusions Adapting an instrument to a domestic context is a complex and time-consuming process, requiring an understanding of the culture where the instrument was developed and where it is to be used. A team, including the instrument’s developers, translators, and researchers is necessary to ensure a valid translation and adaption. This study showed preliminary validity and reliability evidence for the Swedish version (S-SCEAM) when used in a Swedish context. Further, we believe that the S-SCEAM has improved compared to the original instrument and suggest that it can be used as a foundation for future developments of the SCEAM model.

Using an IDMI methodology to make multi-criteria decisions

Multi-criteria decisions usually require measurement or evaluation of performance in different units and their mix by application of weighting factors. This approach leads to potential manipulation of the results as a direct consequence of the applied weightings. In this paper a mechanism has been proposed to overcome this problem. It is known as the : Interlink Decision Making Index (IDMI) and has all the desired features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (i.e. no human weighting needed). The IDMI is capable of reflecting the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (CC) have been chosen. Then, without arbitrarily weighting criteria, comparison and selection of the best possible option can be made. Simple software has been developed to do this numerical transfer and graphic presentation. Two hypothetical examples are presented in the paper to demonstrate the application of the IDMI concept and its advantages over the traditional "tabular and weighting method" in the decision making process.

Reactions to increased workload: effects on professional efficacy of nurses

Research findings support the idea that workload is a significant stressor associated with a variety of deleterious psychological reactions, including burnout, in several different samples of workers. A theoretical model is put forth in the present study in which workload is seen as contributing to distress and depression. Increasingly, organisations are experiencing changes as a result of extensive downsizing, restructuring, and merging. As a result of fiscal restraint, hospitals have been forced to merge, close, downsize, and restructure. Workloads have increased among hospital staff, particularly nurses. This study applies a theoretical model to the understanding of the impact of workload on nurses employed in hospitals experiencing downsizing, particularly on their distress, burnout, and depression. Respondents were 488 nurses who were employed in hospitals that were undergoing restructuring and in which units had already been closed as a result of restructuring. Results of structural equation modeling showed that the data partially fit the model and that workload contributed substantially to levels of depression through distress reactions. Further results showed that cynicism, anger, and emotional exhaustion significantly operationalised distress reactions. This study is unique theoretically in linking anger, cynicism, and emotional exhaustion in a single model that predicts distress levels from workload. The findings that anger, cynicism, and emotional exhaustion operationalised distress indicate the importance of studying patterns of negative reactions and their consequences for depression. Implications of the results are discussed for interventions that can be taken by organisations in order to reduce workloads.

Do teachers of management "Practice what they preach"?

This paper reports on the teaching of management units and examines the teaching practices inline with the management and in particular the leadership and motivation techniques and theories that are taught in these units. The theory challenges the notion that many management academics “Practice what they Preach”. In a dynamic environment that cries out for Transformation Leadership, Transactional management is often the norm. The findings highlight that academics especially management executive academics do “Practice what they Preach” and this counters the argument by some Theory ‘X’ academics that students have an inherent dislike of work and will avoid it if they can. Leading to the only way to get most students to work and study is they must be coerced, controlled, directed, threatened with punishing with bad marks or failure. (McGregor 1960 p34)

Experiential satisfaction with a wholly online marketing unit

This study examines the relationship between students’ satisfaction with a core undergraduate marketing unit, preference for online or face-to-face mode of teaching delivery and intent to major in marketing. The core undergraduate marketing unit was offered only in a wholly online mode, although many of the students had experienced traditional face-to-face classes in previous units. The sample was 112 undergraduate students. Findings indicated students’ preference for face-to-face mode of teaching delivery did not affect satisfaction with the marketing unit, but there was a significant relationship between unit satisfaction and students preference for online mode of teaching delivery. Mode of teaching delivery preferences suggested neither the online or face-to-face mode affected students’ choice in majoring in the marketing discipline, however, there was a significant relationship between student satisfaction and intent to major in marketing.

Students' evaluations of teaching quality and their unit online activity : an empirical investigation

This paper reports on an investigation of the relationship between students’ level of online activity in units in a business faculty and their evaluations of teaching quality in these units. The analysis was conducted using student evaluation data from 2004 to 2007 together with data for student online activity for one semester. We compare on-campus and off-campus students and undergraduate and postgraduate students. The results indicate that students’ evaluations of units have improved on all surveyed criteria during the five years. We also show that for some cohorts student online activity is associated with greater satisfaction with teaching. The paper concludes by considering the implications of these findings for further research and teaching practice.

Do-it-yourself textbook review report card (Checklist)

It is argued that teachers will encounter many changes in teaching approaches and possibly in teaching materials resulting from the development and implementation of the national curriculum. With the new national curriculum, there will be new textbooks which will be 'new' as textbooks, but not necessarily new in mathematical content or instructional approaches. Two critical questions for these textbooks (or any textbooks) are: How good are these textbooks, as textbooks? How well do these textbooks fit whatever the 'new' curriculum is? Other questions to consider are: Is the content 'new' and/or substantial? Is the material 'fair' and representative? Elements of a good textbook are discussed including that it should have good design and provide good definitions, worked examples and counter-examples.

Contemporary management

Contemporary Management, by local author Di Waddell is the second, local adaptation of the US market-leading management text by Jones and George. This unique text follows a nonprescriptive, real-world approach to management and is written in an accessible style allowing for flexibility in both teaching and learning.

Used at both an undergraduate and postgraduate level, Contemporary Management has a concise structure designed to meet the needs of trimesters and 12 week teaching schedules. The uncluttered internal design alongside the modern treatment of the topic makes this text significantly different to other texts in the market.

It offers updated content to reflect the impact of the GFC and the increasing significance of diversity, culture and ethics. There are all new in-chapter case studies, new Australian videos and a full range of excellent online resources. Also, this edition includes a new end of book section containing two unique integrated case studies exploring tourism management in Australian tourism destinations: Skyrail in Cairns and Flinders Island, Tasmania.

Combining vocational and higher education studies to provide dual parallel qualifications – an Australian case study

Developing academic relationships between vocational colleges and universities in Australia has been problematic, with exchanges between the two sectors limited to linear articulation and prescribed credit transfer. Whilst some very good examples of collaboration exist, the two sectors generally operate independently of each other. The isolation of the sectors has meant frustration for students and employers who want a flexible, collaborative model to meet changing industry needs. This paper reports upon a pilot project in construction management at a Melbourne university that attempted to address these needs. It demonstrates how over a five year period, HE students completed electives in practical units within the VET sector. The overwhelming success of the project meant that practical electives were embedded in the construction management programme in 2007 and this paper reports on the third, final phase of the project in 2009/10 which saw construction management students graduate with a dual qualification – both a vocational qualification and a university degree. Interviews conducted in this final phase reveal that students and industry want the benefits of a practical and theoretical qualification. The paper raises critical questions about educational pathways and suggests long-term implications for construction and tertiary education in Australia and internationally.

Health information technology governance : a perspective on investment decision processes

Realizing value from IT investments continues to be a challenge for most healthcare organizations. IT governance (ITG) is envisaged to solve many of these challenges. ITG is the practice that establishes accountability framework for IT investments by allocating decision rights among major participants involved in IT decision processes. As ITG is relatively new in healthcare industry, it is expected that knowledge about how healthcare organizations govern their IT decisions is limited. This research aims to extend this knowledge and to assist both researchers and professionals by providing insights on how IT decisions are made and governed in healthcare organizations (HOs). This research adopts case-study methodology to investigate IT governance in two distinctly different HOs. The research findings indicate that HOs implement ITG to achieve alignment between business objectives and IT. Both HOs set up a five-stage IT decision process to identify, evaluate and prioritize IT investment ideas. They also established generic committee-structures that clearly defined roles and decision authorities to govern such process. It is suggested here that ITG in HOs is heavily influenced by strategic priorities, organizational structure, governance experience and governmental initiatives. Effective ITG in HOs is challenged by IT alignment, policy government, involvement of healthcare executives, and lack of business metrics to justify and evaluate decisions. The research proposes recommendations to address these challenges.
