CAL evaluation: Future directions
Formal, experimental methods have proved increasingly difficult to implement, and lack the capacity to generate detailed results when evaluating the impact of CAL on teaching and learning. The rigid nature of experimental design restricts the scope of investigations and the conditions in which studies can be conducted It has also consistently failed to account for all influences on learning. In innovative CAL environments, practical and theoretical development depends on the ability fully to investigate the wide range of such influences. Over the past five years, a customizable evaluation framework has been developed specifically for CAL research. The conceptual approach is defined as Situated Evaluation of CAL (SECAL), and the primary focus is on quality of learning outcomes. Two important principles underpin this development. First, the widely accepted need to evaluate in authentic contexts includes examination of the combined effects of CAL with other resources and influential aspects of the learning environment. Secondly, evaluation design is based on a critical approach and qualitative, case‐based research. Positive outcomes from applications of SECAL include the easy satisfaction of practical and situation‐specific requirements and the relatively low cost of evaluation studies. Although there is little scope to produce generalizable results in the short term, the difficulty of doing so in experimental studies suggests that this objective is difficult to achieve in educational research. A more realistic, longer‐term aim is the development of grounded theory based on common findings from individual cases
IntCal09 and Marine09 radiocarbon age calibration curves, 0–50,000 years cal BP

This article is posted here by permission of Dept. of Geosciences, University of Arizona for personal use, not for redistribution. The definitive version was published in Radiocarbon 51 (2009): 1111-1150.The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is
here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP, utilizing newly available data sets
that meet the IntCal Working Group criteria for pristine corals and other carbonates and for quantification of uncertainty in
both the 14C and calendar timescales as established in 2002. No change was made to the curves from 0–12 cal kBP. The curves
were constructed using a Markov chain Monte Carlo (MCMC) implementation of the random walk model used for IntCal04
and Marine04. The new curves were ratified at the 20th International Radiocarbon Conference in June 2009 and are available
in the Supplemental Material at www.radiocarbon.org.We would like to acknowledge support for this project from the UK Natural Environment Research

Characterisation of the apparent reflectance of a concrete calibration surface over different time scales
This paper describes results from a detailed field spectral measurement campaign, designed to assess the temporal stability of calibration surface reflectance factors. The results have wider implications for those using field measurements of reflectance in stand-alone studies, or in a calibration/validation context. A dual-field-of-view VNIR spectroradiometer system measured temporal changes in nadir surface reflectance factors at a concrete calibration surface. Reflectance factor variations were assessed in relation to the solar zenith angle (SZA), using the modified Walthall et al. (1985) model. Superimposed on low-magnitude variations in surface reflectance factors with SZA, were larger differences caused by environmental effects. Seasonal changes were caused by activation of a vegetative bloom which caused surface reflectance factors to vary by up to 16% (670nm). A smaller amount of variation was associated with changes in total solar radiation (kWm-2). This was an ‘apparent’ effect, caused by the directional anisotropy of the surface response, in relation to changing distributions of irradiance. A quantitative surface response model was derived empirically, and successfully used to predict concrete surface reflectance factors. The results highlight fundamental differences between inherent and apparent reflectance, and demonstrate that the reflectance factor response of a weathered concrete calibration surface was predictable over a range of timescales

Chapter 03: A Geneticist Pediatrician Joins the Army; Return to Cal Tech
Military Experience: Dr. Knudson talks about his enlistment in the army during the Korean War. He was supposed to spend a year in Korea and a year in the U.S. Instead, he spent two years in Fort Riley, Kansas because the army was not sure what to do with a geneticist pediatrician in Korea.
Education: Dr. Knudson then discusses his return to the California Institute of Technology in 1953 to study. He briefly talks about the influence of Watson and Crick\u27s work on the field of genetics earlier that year. After he finished at Cal Tech, Dr. Knudson was put in charge of a small pediatrics unit at City of Hope Medical Center, which fit his previous experiences well.https://openworks.mdanderson.org/mchv_interviewchapters/1300/thumbnail.jp

Strobilanthes violifolia T. Anderson 1867
Strobilanthes violifolia T. Anderson (1867: 485). Lectotype (designated here): INDIA. Sikkim, Ratong to Yoksum, 25–5000', T. Anderson 1051 (CAL0000019841!). Figure 5B. Pteracanthus violifolius (T. Anderson) Bremekamp (1944: 200). Echinacanthus parviflorus T. Anderson (1867: 459), non Strobilanthes parviflora Beddome (1874). Lectotype (selected by Wood, 1994): INDIA. Meghalaya, Griffith s.n. (K!). Clarkeasia parviflora (T. Anderson) J.R.I. Wood (1994: 189). Echinacanthus andersonii C.B. Clarke (1884: 415). Syntypes: India, Darjeeling, C. B. Clarke 13633 (BM!, CAL, K!).

Echinacanthus siamensis Imlay (1939: 114). Holotype: Thailand, Nan, A. F. G. Kerr 4944 (K!). Clarkeasia parviflora var. albescens Wood (1994: 191), synon. nov. Holotype: West Bengal Duars. Brandis s.n. (K!) This species was treated as Clarkeasia parviflora (T. Anderson) J.R.I. Wood by Wood (1994: 189) but based on subsequent molecular and morphological studies (Carine & Scotland 2002: Moylan et al. 2004), it is clear that the genus Clarkeasia should be included within Strobilanthes, where the oldest available name is S. violifolia. Strobilanthes violifolia is, in fact, sister to Aechmanthera gossypina (Wallich) Nees (Moylan et al. 2004: 732), a species already transferred to Strobilanthes as S. tomentosa (Nees) J.R.I. Wood (Wood & Scotland 2009: 16). The sheet annotated by Anderson at CAL is selected here as the lectotype as we cannot locate any other specimen at K or elsewhere that can be considered for lectotypification. Var. albescens of Clarkeasia parviflora is included in the synonomy as it has no clear geographical patterning and is probably analagous to the lanate forms of Strobilanthes tomentosa (Nees) J.R.I. Wood, treated as a synonym of that species by Wood & Scotland (2009: 21), who postulate that that the white-felt indumentum represents a developmental stage. Given that Strobilanthes violifolia and A. tomentosa are sister species (Moylan et al. 2004) and that at least one intermediate is known (Grey-Wilson & Phillips (K) from Nepal), similar developmental traits in both species might not be unexpected. Strobilanthes violifolia is quite widely distributed being recorded from Nepal, Bhutan, India (Himachal Pradesh, Sikkim, West Bengal, Meghalaya and Manipur) and Thailand (Nan and Kanchanaburi). Its absence from Myanmar is curious and it might be expected to be found there.Published as part of Albertson, Winston D. & Wood, Hn. R.

Barleria lawii T. Anderson 1867
Barleria lawii T. Anderson (1867: 492) Type (lectotype designated here):— INDIA. Bababoodun [Baba Budan] hills, s.d., Law s.n. (CAL barcode CAL0000019892!). Fig. 3. Residual syntypes:— BR No. 694246!; C barcode C10004759!; CAL barcode CAL0000019891!; P barcodes P00719485!, P00719488!, P00719487! and P00719490! Notes: This species was described by Thomas Anderson (1867), who cited two different gatherings in the protologue, viz. ‘in collibus Babadoodun, Law’ [on the hills of Babadoodun (Baba Budan), collected by Law] and ‘in montibus Concan et Malabar, Stocks, Law [in the mountains of Konkan and Malabar collected by Stocks and Law], these two gatherings must be treated as syntypes (Art. 9.6 of the ICN). Shendage & Yadav (2010: 103) indicated “ India, Karnataka, Chikmagalur district, Bababudan hills, Stocks & Law 33 (CAL)” as the type, again failing to satisfy Art. 7.11 of the ICN so their type indication has no standing. We select the specimen from Anderson’s Herbarium collected by Law (CAL0000019892) (Fig. 3). From Bababoodun [Baba Budan] as lectotype as it matches well with the protologue. The other syntype gathering, Stocks & Law 33, from the Hooker et Thomson Herbarium is represented in BR (no. 694246), C (C10004759), CAL (CAL0000019891), and P (P00719485, P00719488, P00719487 and P00719490).Published as part of Patil, Suraj S., Deshmukh, Pradip V. & Lekhak, Manoj M., 2022, Typification of some names in Indian Barleria L.
