Methods and Materials. For each of the 18820 pairs of the ad-hoc retrieval runs of TREC 3, 5–8, we computed the two-sided statistical sig- nificance (p-value) of the difference in the pair’s mean aver- age precision using each of three tests: the randomization, shifted bootstrap, and Student’s paired t-test. Both the ran- domization and bootstrap are distribution-free tests. Space limitations prevent us from explaining the details of each of these well-known tests. For both the randomization and bootstrap, we performed 100,000 samples. For each pair of runs, we sampled topics without replacement to produce runs with 10, 20, 30, and 40 topics. To compare significance tests, we computed the root mean square error between each test and each other test’s p-values. The root mean square error is: Copyright is held by the author/owner(s). 1 ΣN (Ei − Oi)2 1/2 ACM 978-1-60558-483-6/09/07.

Methods and Materials. The first set of studies was designed to better docu- ment and quantify the variations between British and American English in the use of plural number when an agreement target’s controller or antecedent has a collective head. We gathered two types of data from British and American speakers and writers. First, to assess verb agreement using matched collective and noncollective materials under comparable conditions, we elicited spoken sentence completions from American and British college students. The collective nouns sampled were chosen from a diction- ary of collectives (Xxxxxxx 1985) to represent a range of human (team, committee), nonhuman animate (herd, flock), corporate (government, association), and ostensibly inanimate (fleet, forest) groupings. Second, for a subset of these collectives we carried out counts of singular andplural verb andpronoun agreement with collective controllers in the Wall Street Journal corpus and the British National Corpus. SPOKEN SENTENCE COMPLETIONS. To compare the incidence of plural agreement after collective controllers with the incidence of plural agreement after semantically related plural and singular noncollectives, thirty-nine students at Michigan State University and thirty-nine students and research workers at Cambridge University provided spoken sentence completions. The completion test was assembled from ninety-six triplets of semantically relatednouns (see Appendix A). Each triplet consistedof a collective (e.g. army), a semantically related noncollective singular (e.g. soldier), and the correspond- ing plural (e.g. soldiers). Three lists of ninety-six simple definite noun phrases were assembledfrom these triplets, with one noun in each noun phrase (e.g. the army). Every list contained one noun from every set and an equal number of nouns of each of the three types (collective, singular, andplural). Across the three lists, every noun occurred just once. The order of the nouns within lists was random, constrained so that there were no more than two successive occurrences of the same kind of noun. The same random order was used for all three lists, so that nouns from the same triplet occurred in the same ordinal position in every list. Each list began with the same four practice items, consisting of two noncollective singulars and two noncollective plurals that differed from the noun phrases used within the lists. The phrases were presented to participants individually under computer control, each phrase appeari...
Methods and Materials. The current study employed quantitative method to examine factors of TAM toward ICT use for English language learning. Besides, it investigated students' activities related to the usage of ICT for general and English language learning purposes. This study used a convenience sample of 303 student teachers of the English Department at a state university in Jambi, Indonesia. The the studentpre-service participants are all teachers majoring English from the first-year to the fourth-year students enrolled in 2020. The student teachers had formally learned English for three years at secondary school level, three years at high school level, and continue to study English courses as well as receive instruction through the medium of English during their undergraduate study at university. Two hundred thirty-seven respondents are were female (78.2%), and sixty-six respondents are were male (21.8%). The primary instrument to collect data in this study was a questionnaire. The online developed questionnaire survey was modified by the researchers based on the research question and previous related studies in a close-ended format, and distributed to all of the respondents. The developed modified questionnaire consists of 33 items. The first section elicited background information of the respondents including gender, academic years, ICT devices ownership, the use of ICT for English learning purposes, and their activities in using ICT for English learning purposes (5 items). The second section entailed the variables of TAM in using ICT for English language learning, which included equipment (Eq), 2 items (adapted from Sabti & Xxxxxxxx, 2014); motivation (Mo), 2 items (adapted from Xxxxx & Xxxxxxxx, 2014); ICT skills (Sk), 3 items (adapted from Sabti & Xxxxxxxx, 2014); perceived ease of use (PEoU), 5 items (adapted from Xxxxxx, 1989; Park, 2009; and Venkatesh & Xxxxxx, 2000); perceived usefulness (PU), 5 items (adapted from Xxxxxx, 1989; Park, 2009, and Xxxxxxxxx & Xxxxxx, 2000); attitude (At), 3 items (adapted from Xxxxxx, 1989; Park, 2009, and Xxxxxxxxx & Xxxxxx, 2000); and actual use (AU), 4 items (adapted from Xxxxxx, 1989; Xxxx, 2009, and Xxxxxxxxx & Xxxxxx, 2000), with four-point Likert-type scales, from 1 = strongly disagree to 4 = strongly agree. Before administering the instrument questionnaire in this study, a representative group (25 students) who were not involved in the main study were piloted to allow the researchers to identify and adjust the instrument.

Methods and Materials. Ethics Participants
Methods and Materials. Landlord may arrange for the performance of the Base Building Work in such manner as Landlord shall determine in its sole discretion, consistent, however, with the Base Building CD's as finally approved, Legal Requirements and the provisions of this Section 16.6. There shall be no substitutions for any item of Base Building Enhancements without the consent of Tenant, which consent shall not be unreasonably withheld, provided, that it shall not be reasonable for Tenant to withhold consent for any substitution (i) which does not increase the Tenant Initial Work Cost, (ii) where the item being substituted for will not be available in time to complete the Base Building Work on schedule (and was ordered timely), (iii) which is of substantially equal or better quality and performance characteristics (including projected costs of operation and maintenance) than the item being substituted for and (iv) which complies with Legal Requirements. Notwithstanding anything to the contrary in the preceding sentence, Tenant's approval for such a substitution which affects the appearance of the Premises may be withheld in Tenant's sole discretion. For purposes hereof, the term substitution means a change in product, materials, equipment or method of construction as shown or described in the Base Building CD's as finally approved. If Tenant`s approval for any substitution of equipment, materials or personnel is required, Landlord shall submit its request therefor to Tenant in writing. Tenant shall approve or disapprove Landlord's request in writing within a reasonable period of time (given the nature and scope of the proposed substitution), not to exceed five (5) Business Days, after Tenant's receipt of Landlord's reasonably detailed request therefor. If Landlord's request contains a statement that Tenant's failure to respond to such request within the time limitations set forth in the preceding sentence shall constitute Tenant's approval of Landlord's request, then Tenant's failure to respond within the time limitations set forth in the preceding sentence shall be deemed to be the granting of Tenant's approval. If a substitution for any item of Base Building Enhancements reduces the cost of such item, the increase in Tenant Initial Work Cost previously accepted by Tenant in connection with such item shall be appropriately adjusted to reflect such reduction in cost.
Methods and Materials. The method was developed and refined through a series of failed pilots discussed in the Appendix. The main experiment consisted in acceptability judgments, complemented in some cases with semantic questions to check that the 'stripping' construction was understood in the expected fashion.
Methods and Materials. Cliff swallows nest at sites that have three primary attributes: (1) a vertical surface with an overhang for nest attachment, (2) an open area for foraging, and (3) a mud supply of the proper consistency for nest building (Emlen 1954). However, many other factors play a role in determining whether a site will be selected for nesting. To determine the likelihood of xxxxx xxxxxxx nesting on a particular bridge structure, we developed a habitat selection model based on several site characteristics. We first randomly selected 300 bridges from the Caltrans state bridge log. Bridges were limited to those within a 100-mile radius of UC Xxxxx and with a length less than 500 ft. The 100 mile radius allowed multiple site analyses in single-day trips but at the same time provided geographical diversity (e.g., Coast Range, Sacramento Valley, San Xxxxxxx Valley, Sierra Nevada foothills, and mountains). As part of this requirement, we selected bridges only within Caltrans districts 1, 3, 4, and 10. Distance to each bridge was determined by converting latitude and longitude from bridge log entries to Universal Transverse Mercator (UTM) coordinates and calculating the vector length to UTM coordinates for UC Davis. Xxxxxxx over 500 ft were considered too long to be surveyed without boats or in a reasonable amount of time. Duplicate entries in the bridge log were also eliminated from the selection list. We obtained encroachment permits from districts 1, 3, 4, and 10 for the 300 randomly selected bridges. Since the physical characteristics of the sites did not change greatly in the short-term, the timing of the surveys was not restricted to the breeding season when birds were present. Between January and November 2007, we visited bridges to collect on-site characteristics of the bridge structure, xxxxx xxxxxxx nesting evidence, and surrounding habitat. Sites that were deemed unsafe or difficult to reach by car or foot were eliminated. Several sites were not surveyed due to the time constraints of our daily trips. We ultimately surveyed 206 bridges (Appendix E) which were well interspersed within the 31-thousand square-mile region of study. Prior to site visits, we printed aerial photographs of each bridge site using Google Earth (Google Inc., Mountain View, California) and created data collection sheets containing information from the Caltrans bridge log and blank spaces for data collected in the field. The aerial photographs showed the surrounding habitat within a 4 km2 are...
