Young children’s views of the technology process: an exploratory study

This paper describes an exploratory study of an aspect of the technological knowledge of two groups of five-year-old students in their first year at school. Their emerging understandings of the steps required to develop a new product were investigated through a series of interviews. A theoretical framework linking technological knowledge to ‘funds of knowledge’ from experiences outside the classroom supported the analysis. The data suggest that young children draw on a broad range of experiences and knowledge, often uncritically, in order to explain how things are made. They are able to transfer their understandings of the technological process from one experience to another particularly when they have the language and background experiences to support them. Of particular note however, is that they were often unfamiliar with the properties of materials and therefore unable to anticipate the processes necessary to convert raw materials into a final product. The research also highlighted some key considerations for working with young children in this area.     

Internationalization of Small Family Firms: The Influence of Family from a Socioemotional Wealth Perspective

We explore the factors influencing the internationalization of small family firms. Based on interviews with six family firms in Singapore, we highlight the importance of (1) family harmony, (2) trust in external relationships, (3) social and business networks, and (4) organizational resources and capabilities in the internationalization process. We show how the socioemotional wealth factors of trust and harmony affect networking and resources, which in turn affect internationalization. We find that initial internationalization through exports is enabled through trust in family networks, but the typical family characteristics of a desire to maintain family harmony and distrust of outsiders have a negative impact on network creation and resource development, which constrains the extent to which the firm internationalizes beyond exporting. In order to move from the first stage (exports/similar markets) to the second stage (joint ventures/different markets) of internationalization, less emphasis on trust and family harmony accompanied by more emphasis on building external networks and resources may be necessary. We propose a new model of internationalization of family firms based on our findings. © 2015 Wiley Periodicals, Inc.     

Cost-effectiveness of hydrophilic-coated intermittent catheters compared with uncoated catheters in Canada: a public payer perspective

Study design: A Markov model was used to analyze cost-effectiveness over a lifetime horizon.

Objective: To investigate the cost-effectiveness of hydrophilic-coated intermittent catheters (HCICs) compared with uncoated catheters (UCs) among individuals with neurogenic bladder dysfunction (NB) due to spinal cord injury (SCI).

Setting: A Canadian public payer perspective based on data from Ontario; including a scenario analysis from the societal perspective.

Methods: A previously published Markov decision model was modified to compare the lifetime costs and quality-adjusted life years (QALYs) for the two interventions. Three renal function and three urinary tract infection (UTI) health states as well as other catheter-related events were included. Scenario analyses, including utility gain from compact catheter and phthalate free catheter use, were performed. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model.

Results: The model predicted that a 50-year-old patient with SCI would gain an additional 0.72 QALYs if HCICs were used instead of UCs at an incremental cost of $48,016, leading to an incremental cost-effectiveness ratio (ICER) of $66,634/QALY. Moreover, using HCICs could reduce the lifetime number of UTI events by 11%. From the societal perspective, HCICs cost less than UCs, while providing superior outcomes in terms of QALYs, life years gained (LYG), and UTIs. The cost per QALY further decreased when health-related quality-of-life (HRQoL) gains associated with compact HCICs or catheters not containing phthalates were included.

Conclusion: In general, ICERs in the range of CAD$50–100,000 could be considered cost-effective. The ICERs for the base case and sensitivity analyses suggest that HCICs could be cost-effective. From the societal perspective, HCICs were associated with potential cost savings in our model. The results suggest that reimbursement of HCICs should be considered in these settings.     

Inequality Stagnation in Latin America in the Aftermath of the Global Financial Crisis

Between 2003 and 2010, Latin America experienced a solid record of economic growth, coupled with a notable reduction in income inequality. The regional Gini coefficient fell from 0.556 to 0.521 and declined in all 15 out of 17 countries in which frequent data are available. However, previous studies have warned about problems in the sustainability of the decline in income inequality and this study presents evidence of stagnation on this front between 2010 and 2013. The results are robust to various measures of income inequality, but differ across the region. While largely attributable to the recovery from the global financial crisis in Mexico and some countries in Central America, the results are also supported by the demonstrated slowdown in inequality reduction in other countries, including Brazil, Ecuador and Bolivia.     

Explosive decomposition of ethylene oxide

The purpose of this work was to obtain data on explosive limits for ethylene oxide (EtO) in nitrogen beyond the published data range. Tests were conducted at temperatures from 60°-190°C and pressures in the range 10 to 80 psig. Initial measurements showed that the limits for the EtO/N₂ system are unusually dependent on the details of the ignition source. Hot wire ignition gave very erratic responses. Induction coil sparks were not satisfactory due to inadequate energy and uncertain gap breakdown at elevated pressure. However, high-energy capacitive discharge across an exploding bridge element tuned to the ignitive process gave responses that were reproducible and judged to be true and conservative. Graphite filament was used as the exploding bridge “wire” to avoid contamination of the test mixture. (Carbon is a product of EtO explosions.) The data from this study show the EtO explosive range becomes wider with increasing pressure at the low end of the temperature range examined than previously understood from literature data. At modest pressures, the directly-measured limits at elevated temperature agree with extrapolations of earlier reported data. Because of the pressure nonlinearity, the system is deemed safer at 80 psig and high temperature than had been predicted from the linear treatment.     

Explanations for continued gender discrimination in South Korean workplaces

This paper investigates potential explanations for the continued gender discrimination in South Korean workplaces despite decades of gender policy reforms and improved education for women. Making use of both primary and secondary data sources, the institutional theory, the voluntary compliance regulatory enforcement strategy and the typology of regulatory noncompliance provide a framework from which four explanations regarding the origin and nature of Korean firm equal opportunity (EO) compliance issues are derived. Identified through data analysis, explanations include a lack of legal enforcement, a weak punishment system, a tacit acceptance of the status quo by women, organizational cultural issues stemming from the traditional Korean mind-set that allow gender discrimination and a general lack of knowledge about EO regulations by many companies. Reforms and paradigm changes addressing these gender policy compliance issues could yield considerable social benefits in reducing the scope and quantity of gender discrimination in Korean workplaces.     

Comparative effectiveness and student choice for online and face-to-face classwork

The authors examined learning and task choices made by students when the same interactive course design was used online and face-to-face. A survey was administered in an operations management course covering both conceptual and quantitative topics. Course grades were compared and correlations were measured to determine relevant relationships. Results showed that online students performed equally as well as face-to-face students. The most important task choice for face-to-face success was regular class attendance, whereas for online students it was completion of interactive worksheets. Passive textbook reading was neither chosen as often, nor significant to student success. Minimal uncertainty was important to success, with self-discipline, clarity of instructions, and virtual presence of an instructor most important.     

An investigation into the development and progressive adaptation of graduate attributes in tourism programmes

As higher education institutes are embracing the notion of graduate attributes, it has become highly desirable to embed these attributes within programmes. This study proposes to investigate students’ views of recently identified graduate attributes in the Dublin Institute of Technology (Ireland), and how they perceive their development and application in their tourism programme. The study supports the idea of the importance of placement in the progressive adaptation of learning and in translating the conception of attributes. While students strongly believe that graduate attributes are developed through the placement experience, it is equally important to embed and strengthen the visibility of the graduate attributes building blocks throughout the programme.
