Job Crafting and Identity in Low-Grade Work: How Hospital Porters Redefine the Value of their Work and Expertise

Over 25 years ago, Brown and Duguid (Organisation Science, 2(1), 40–57, 1991) highlighted the differences between the way organisations formally describe and delineate jobs and the actual practices of their employees. This paper combines ideas from their seminal contribution with theories of ‘job crafting’ and identity to examine the agentic behaviour of employees in low-grade, ‘dirty work’ as they utilise their expertise and practices to (re)frame their occupational identities and challenge their prescribed job boundaries. The evidence for the paper comes from a qualitative study of hospital porters in the UK’s National Health Service. It argues that this combined theoretical approach provides a potential research and employment framework to challenge the abstracted and stereotypical conceptions of the expertise related to low-grade jobs.     

Raising the bar on studying cultural evolution

Sasaki and Biro (2017, Nature Communications, 8, 15049) show that pairs of pigeons can increase the efficiency of their homing routes over several ‘generations’ in which pair members are gradually replaced by naïve birds. Their findings show that socially transmitted cumulative alterations of behavior are not unique to humans and suggest a way to examine potential mechanisms of cultural evolution.     

An Investigation of How Culture Shapes Curriculum in Early Care and Education Programs on a Native American Indian Reservation

This article investigates how culture shapes instruction in three early care and education programs on the Flathead Indian Reservation. Interviews with eight early childhood teachers as well as classroom observations were conducted. The investigation is framed by the following research question: How does the culture of the family and community shape curriculum? Data analysis suggested that ongoing communication with parents and community about teaching within a culturally relevant context, building a sense of belongingness and community through ritual, and respecting children, families, and community were essential to defining the Native American Indian culture within these early learning programs.     

A COMPARISON OF THE RELIABILITY AND VALIDITY OF TWO METHODS FOR ASSESSING PARTIAL KNOWLEDGE ON A MULTIPLE-CHOICE TEST

Differential weighting of response alternatives and confidence testing have been proposed as ways to assess partial knowledge on multiple-choice tests. 211 students in an educational measurement course took their midterm examination under one of three procedures. Results from those students administered the test under conventional directions provided a baseline for comparing, in terms of reliability and validity, the results from students who took the test under the differential weighting of response alternatives or the confidence testing instructions. Reliability was estimated by the split-half technique. Validity was estimated by correlating midterm test scores with scores on a final examination. This investigation provides some support for the contention that validity can be improved using more sophisticated testing techniques. Suggestions for the conduct of more definitive studies were offered.     

Effects of Second-Order Difference-Frequency Wave Forces on Floating Wind Turbine Under Survival Condition

In this paper, the effects of second-order difference-frequency wave forces on the global motion of an offshore wind turbine system with a large displacement under the survival condition are studied. In this case, the hydrodynamic force is the main force because the blades are feathered to reduce the lifting force. The first-order hydrodynamic forces are calculated by WADAM, while the second-order wave forces are calculated by a customized MATLAB module. Then the hydrodynamic coefficients are transferred to the wind turbine analytical code FAST. Through the comparisons of dynamic responses between the first- and second-order numerical models, it is found that the second-order wave forces significantly influence the motion of floating wind turbine under the survival condition. Moreover, neglecting the second-order force significantly underestimates the tension forces in the mooring lines.     

Mnemonic artwork-learning strategies: Helping students remember more than “Who painted what?”

In two experiments, a recently devised mnemonic strategy was examined in the context of college students recalling the theme and contents of various paintings. With the painting-artist mnemonic strategy: (a) the artist's name is first recoded as a more concrete proxy; and (b) the recoded stimulus is then related to a prominent feature of the painting. Previous research has demonstrated that such a strategy enhances students' recall of artist names when cued with the associated paintings. The present study extends those findings by demonstrating that the strategy similarly facilitates students' recall of paintings and painting information when cued with the associated artist names. Of three different mnemonic variations included, one that incorporates a verbally described mnemonic interaction into the painting proved most effective. Suggestions for future research and educational implications are included in the discussion.
