True value: Calculating and communicating the value of library labor

We have seen a multitude of methods used to calculate and communicate the value of libraries to society. However, most of the existing techniques—such as return on investment or individual receipts that provide cost savings information to patrons—focus on the value of resources and services: that is, the products provided to library users and related stakeholders. None of these calculations quantitatively consider the value inherent in the labor necessary to provide those resources and services and make them available. This project draws on critical design (Dunne 1999; Bardzell & Bardzell 2013)—a specific form of activist research inquiry that uses the creation of provocative artifacts to challenge established assumptions, shift perspectives, and think in new ways—to uncover and communicate the value of library labor. Using the results of a nationwide survey distributed to librarians and library workers in varying contexts, we are creating an interactive website that will allow library users and other stakeholders to calculate the value of library services, including the value of labor. Without this fundamental consideration, librarianship will always lack successful communication of true calculation of value—one that may lead to increased understanding of the full range of what libraries offer society

Rarely acknowledged and often unrecognized: Exploring emotional labor across library work tasks

In the seminal work on emotional labor (EL), Arlie Hochschild (1983, 2012) defines EL as “the management of feeling to create a publicly observable facial and bodily display.” EL is “sold for a wage” (Hochschild, 2012). To date, there have been a few studies on emotional labor in librarianship. Julien and Genuis (2009) found EL to have a central place in the experiences of instructional librarians. Shuler and Morgan (2013) interviewed reference librarians, finding they are expected to perform EL yet are not formally trained to do so. Matteson and Miller (2013) surveyed librarians nationwide, with statistical analysis confirming EL present in librarianship. Matteson et al. (2015) asked MLIS holders to reflect via diary entries on performed EL. The results of these studies have clearly demonstrated EL as a part of librarianship. To further advance the study of EL in librarianship, our work offers a quantitative perspective on EL across different types of library labor. We used a nationwide survey, recording types of library work performed, EL labor relative to task performed, with a section for open-ended comments. We sought to include all library workers, with a shorter questionnaire that still covers the established components of EL, such as hiding negative emotion. We will discuss how EL happens across the librarianship, with specific attention to differences to EL amongst various library tasks and between academic and public libraries based on the results of the survey, and implications for future studies

Problems in deriving Italian regional differences in intelligence from 2009 PISA data

Recent results of international assessment programs (e.g., PISA) have shown a large difference in high school students' performance between northern and southern Italy. On this basis, it has been argued that the discrepancy reflects differences in average intelligence of the inhabitants of regions and is associated with genetic factors (Lynn, 2010a and Lynn, 2012). This paper provides evidence in contrast to this conclusion by arguing that the use of PISA data to make inferences about regional differences in intelligence is questionable, and in any case, both PISA and other recent surveys on achievement of North and South Italy students offer some results that do not support Lynn's conclusions. In particular, a 2006–2009 PISA data comparison shows a relevant decrease in the North–South difference in only three years, particularly evident in the case of a single region (Apulia). Other large surveys (including INVALSI-2011) offer different results; age differences suggest that schooling could have an important role

A viscoelastic deadly fluid in carnivorous pitcher plants

Background : The carnivorous plants of the genus Nepenthes, widely distributed in the Asian tropics, rely mostly on nutrients derived from arthropods trapped in their pitcher-shaped leaves and digested by their enzymatic fluid. The genus exhibits a great diversity of prey and pitcher forms and its mechanism of trapping has long intrigued scientists. The slippery inner surfaces of the pitchers, which can be waxy or highly wettable, have so far been considered as the key trapping devices. However, the occurrence of species lacking such epidermal specializations but still effective at trapping insects suggests the possible implication of other mechanisms. Methodology/Principal Findings : Using a combination of insect bioassays, high-speed video and rheological measurements, we show that the digestive fluid of Nepenthes rafflesiana is highly viscoelastic and that this physical property is crucial for the retention of insects in its traps. Trapping efficiency is shown to remain strong even when the fluid is highly diluted by water, as long as the elastic relaxation time of the fluid is higher than the typical time scale of insect movements. Conclusions/Significance : This finding challenges the common classification of Nepenthes pitchers as simple passive traps and is of great adaptive significance for these tropical plants, which are often submitted to high rainfalls and variations in fluid concentration. The viscoelastic trap constitutes a cryptic but potentially widespread adaptation of Nepenthes species and could be a homologous trait shared through common ancestry with the sundew (Drosera) flypaper plants. Such large production of a highly viscoelastic biopolymer fluid in permanent pools is nevertheless unique in the plant kingdom and suggests novel applications for pest control
