No full textChlopsis bidentatus sp. nov. (Figs. 1, 2, 3B) Holotype: MNHN 2001-1080, 167 mm total length, New Caledonia, 23º 48' S, 168º 17' E, depth 444-503 m, captured with beam trawl, Campagne Bathus 3, Station CP 814, 28 November 1993. Paratype: MNHN 2001-1078, 132 mm TL, Fiji, Somo-Somo Strait, 16E 27 í S, 179E 34.8' W, depth 300-370 m, captured with Waren dredge, Campagne Bordau 1, Station DW 1454, 04 March 1999. Diagnosis. Distinguished from all other members of the genus Chlopsis by the combination of the following characters: pigmentation bicolored, dorsal origin approximately one eye-diameter behind gill opening, and vomerine dentition in two biserial rows anteriorly. Description. Total vertebrae 125 (128), predorsal vertebrae 11 (11), preanal vertebrae 31 (32), precaudal vertebrae 42 (41). Proportions as percent of TL: predorsal length 13.2 (13.8), preanal length 33.5 (34.2), head length 11.1 (10.3), depth at anus 2.9 (2.6). Proportions as percent of head length: eye diameter 13.4 (13.5), interorbital width 12.1 (10.6), snout length 22.9 (22.1), tip of snout to rictus of jaw 35.0 (33.6). Body moderately elongate, slightly compressed. Dorsal fin begins slightly more than one eye diameter posterior to gill opening (Fig. 6). Head moderate in length, relatively deep. Snout relatively broad. Gape short, rictus at posterior margin of eye. Anterior nostril tubular, slightly behind tip of snout, directed anterolaterally. Posterior nostril a posteroventrally directed low tubular opening (covered by a flap) on lip in front of vertical from middle of eye. Lateral line on body absent except for one pore in branchial region, anterior to the gill opening (Fig. 6). Supraorbital pores three: first (ethmoidal) at anteroventral tip of snout, second anteromedial to base of anterior nostril, and last above and behind anterior nostril. Infraorbital pores four: first just behind anterior nostril, second midway between anterior and posterior nostrils, third below posterior nostril, and last below middle of eye. Preoperculomandibular pores five; first near tip of lower jaw, second below interspace between anterior nostril and infraorbital pore 1, third below interspace between infraorbital pores 1 and 2, forth below posterior nostril, and last below and slightly posterior to infraorbital pore 4. Maxillary teeth (Fig. 3B) conical, slightly recurved, in 2-3 irregular rows, increasing in size from outer to inner, a total of 18-20 teeth in the inner row. Intermaxillary teeth conical, slightly recurved, with approximately 20 teeth in a round patch (more teeth can be seen on a radiograph of the holotype, but only about 20 penetrate through the tissue in the mouth). Mandibular teeth like those of the maxilla, except in 4-5 irregular rows anteriorly, reducing to 2-3 posteriorly, with 16-20 teeth in the inner row. Vomerine dentition shorter and stouter, slightly compressed, in two longitudinal series, weakly biserial anteriorly and uniserial posteriorly, 15-16 slightly larger teeth in the longer inner row, and 7-8 smaller teeth in the outer biserial row. Dentition of paratype very similar in both counts and arrangement to those of the holotype. Color of body light brown above and distinctly white ventrally; ventral light area strongly demarcated from the darker dorsum of the snout, starting on unpigmented anterior nostril, continuing back above posterior nostril to ventral margin of eye; tip of lower jaw also pigmented (Fig. 6); posterior to eye, dorsal edge of ventral light area becomes more irregular, but extends dorsally to the gill opening; ventral light area then tapers to base of anal fin slightly behind anus, but continues along base of anal fin for approximately 2/3 of body length; anal fin remains unpigmented to near tip of tail; ventral base of caudal fin and posterior portion of anal fin base much darker than rest of body. Etymology. The name bidentatus is from the Latin bi (two) and dentatus (toothed) in reference to the distinctive vomerine dentition. Remarks. Chlopsis bidentatus is similar in overall appearance to several other members of the genus Chlopsis. Chlopsis apterus, C. bicollaris and C. kazuko, all from the eastern Pacific Ocean, are all also bicolored. The posterior origin of the dorsal fin (at least one eye diameter behind the gill opening) separates C. bidentatus from C. bicollaris and C. kazuko. Chlopsis apterus, which also has the dorsal origin behind the gill opening, has a higher vertebral number (125-128 in C. bidentatus versus 134-140 in C. apterus). Chlopsis bicolor, from the Atlantic Ocean, is very similar in both meristics and morphometrics, as well as in its coloration. Several aspects of the dentition of C. bidentatus, especially the anterior biserial vomerine dentition, clearly separate C. bidentatus from C. bicolor. All other species in the genus Chlopsis can be distinguished from C. bidentatus by coloration. Chlopsis olokun, from the eastern Atlantic, is a fairly uniform tan or gray color, while C. dentatus (from the Atlantic and Indian Oceans) and C. slusserorum (described herein from the Pacific) have banded, blotched or mottled coloration. In the past, differences in vomerine dentition like that described for C. bidentatus would result in the description of a new genus; for example, Robinsia in Böhlke and Smith (1967), and Boehlkenchelys in Tighe (1992). However, due to the overall morphological similarity of this species to that of others in the genus, and the lack of any hypothesis of relationships within the family, we have taken the conservative approach of describing it within the genus Chlopsis. Relationships within the family are being studied by the senior author, and may later determine whether or not this is the correct decision.Published as part of Kenneth A. Tighe & John E.

Which Comforting Messages Really Work Best? A Different Perspective on Lemieux and Tighe\u27s Reciever Perspective
Get PDFThis article responds critically to a recent article by Lemieux and Tighe (Communication Research Reports, 21 , 144–153, 2004 ) in which the authors conclude that recipients of comforting efforts prefer messages that exhibit a moderate rather than high level of person centeredness. It is argued that an erroneous assumption made by Lemieux and Tighe about the status of “receiver perspective” research on the comforting process led to faulty interpretations of the data and unwarranted conclusions about recipient preferences regarding comforting messages. Alternative interpretations of Lemieux and Tighe\u27s data are presented; these are guided by the extensive previous research that has assessed evaluations and outcomes of comforting messages

(Figs. 1, 2, 3A, 4) Holotype: MNHM 2001-1079, 141 mm total length, Fiji, Somo-Somo Strait, 16º 27' S, 179º 35.4' W, depth 426-487 m, captured with Waren dredge, Campagne Bordau 1, Station DW 1393, 23 February 1999. Paratype: AMS I.17284-001, 86 mm TL, Solomon Islands, Malaita Island, S of Aoki, 8º 24' S, 160º 35' E, depth ca. 366 m, collector: P. Coleman, 27 August 1973. Diagnosis. The high vertebral count combined with the distinctive pigmentation differentiates this species from all others in the genus Chlopsis. Description. Total vertebrae 138 (138), predorsal vertebrae 12 (12), preanal vertebrae 40 (41), precaudal vertebrae 60 (56). Proportions as percent of TL: predorsal length 13.2 (13.8), preanal length 33.5 (34.2), head length 11.1 (12.1), depth at anus 2.9 (2.6). Proportions as percent of head length: eye diameter 13.4 (13.5), interorbital width 12.1 (10.6), snout length 22.9 (22.1), tip of snout to rictus of jaw 35.0 (33.6). Body moderately elongate, slightly compressed. Dorsal fin begins slightly more than one eye diameter posterior to gill opening (Fig. 2). Head moderate in length, relatively deep. Snout relatively broad. Gape short, rictus below posterior margin of eye. Anterior nostril tubular, slightly behind tip of snout, directed anterolaterally. Posterior nostril a postero-ventrally directed low tubular opening (not covered by a flap) on lip in front of vertical from middle of eye. Lateral line on body absent except for one pore in branchial region, anterior to the gill opening (Fig. 2). Supraorbital pores three: first (ethmoidal) at anteroventral tip of snout, second anteromedial to base of anterior nostril, and last above and behind anterior nostril. Infraorbital pores four: first just posterior to anterior nostril, second midway between anterior and posterior nostrils, third just behind posterior nostril, and last below posterior edge of eye. Preoperculomandibular pores five; first near tip of lower jaw, second below interspace between anterior nostril and infraorbital pore 1, third below interspace between infraorbital pores 1 and 2, forth below posterior nostril, and last below and slightly posterior to infraorbital pore 4. Maxillary teeth (Fig. 3A) conical, slightly recurved, in 2 irregular rows; inner row larger than outer, a total of 30-31 teeth in the inner row. Intermaxillary teeth conical, slightly recurved, with approximately 20 teeth in a round patch; median and posterior teeth somewhat enlarged. Mandibular teeth like those of the maxilla, except in 2-3 irregular rows anteriorly, reducing to 2 rows posteriorly, with 25-27 teeth in the inner row. Vomerine teeth similar in shape and size to enlarged inner rows of maxillary and mandibular teeth; in two longitudinal series, converging near the end of the tooth rows into a single, irregular median row of small teeth reaching slightly behind the maxillary tooth rows; total of 20-21 teeth in each longitudinal series and 2 small teeth in the median row. Base color of body light tan; dorso-lateral surface of body overlaid with a series of circa 30-35 dark brown blotches (Figs. 1 and 4); blotches either do not extend to the dorsal surface (anterior to dorsal fin origin or near tail) or only weakly extend to the dorsal fin base (which is lightly pigmented for most of its length); blotches do not line up in pairs with blotches on other side of body (Fig. 4). Etymology. We are pleased to name this distinctive eel in honor of Marion and Willis Slusser, in recognition of their keen interest in natural history and generous support of research and education. Remarks. Chlopsis slusserorum is very similar in pigment pattern to C. dentatus from the western Atlantic and western Indian Oceans, which resulted in the paratype being misidentified as C. dentatus by Smith (1989). However, the higher vertebral count (138 versus 116-124) clearly separates the two species. All other species of the genus Chlopsis have either relatively uniform coloration or are distinctly bicolored. Nearly all of the description is based only on the holotype due to the small size and poor condition of the paratype. The paratype apparently became dessicated some time in the past, and the position and number of pores could not be determined. In addition, the lower jaw was badly broken and teeth were missing. Therefore, tooth counts could only be approximated. However, we believe the two specimens to be conspecific, given the similarity in pigment pattern and vertebral numbers.Published as part of Kenneth A. Tighe & John E.

How to use: a pH study
No full textThe 24 h oesophageal pH study is considered to be the gold standard for quantifying acid reflux.1 In this review we provide an evidence-based discussion of the role of 24 h pH studies as part of the investigation of children with suspected gastro-oesophageal reflux disease (GORD), and provide a practical guide on when a pH study is indicated, how to perform pH studies and how to interpret the results.BackgroundGastro-oesophageal reflux (GOR) is defined as the effortless regurgitation of gastric contents into the oesophagus. GORD is defined as GOR associated with sequelae (table 1) including faltering growth.2View this table: * In this window * In a new windowTable 1 Symptoms associated with gastro-oesophageal reflux diseasePhysiological reflux is common in both primary and secondary care settings, and usually improves with age.3 Improvement is due to a combination of factors including growth in the length of the oesophagus, a more upright posture, increased tone of the lower oesophageal sphincter, and a more solid diet. In most cases, diagnosis is based on clinical assessment without the need for invasive testing. Investigation is reserved for those children in whom, for example, there is doubt about the diagnosis, or empirical therapy is considered to have failed, or for those children with extra-intestinal manifestations, such as acute life threatening events (ALTEs), apnoeas, Sandifer syndrome, asthma or faltering growth, in whom reflux is suspected to be a contributing factor.In children with co-existing problems, such as asthma, cerebral palsy, epilepsy or congenital heart disease, GORD may be part of a complex interaction of pathologies as a primary or secondary phenomena. In such settings children may benefit from the diagnosis and treatment of GORD, and GORD may be improved by optimal treatment of the child’s co-existing problems.Children with isolated GORD can remain symptomatic into adulthood; severe oesophagitis4 and oesophageal strictures from GORD in childhood have been reported.5<br/
