Citation expectations: are they realized? Study of the Matthew index for Russian papers published abroad
No full textWe consider the "Matthew effect" in the citation process which leads to reallocation (or misallocation) of the citations received by scientific papers within the same journals. The case when such reallocation correlates with a country where an author works is investigated. Russian papers in chemistry and physics published abroad were examined. We found that in both disciplines in about 60% of journals Russian papers are cited less than average ones. However, if we consider each discipline as a whole, citedness of a Russian paper in physics will be on the average level, while chemistry publications receive about 16% citations less than one may expect from the citedness of the journals where they appear. Moreover, Russian chemistry papers mostly become undercited in the leading journals of the field. Characteristics of a "Matthew index" indicator and its significance for scientometric studies are also discussed

Multilocus sequence typing: Data analysis in clinical microbiology and public health
No full textNumerous computer-based statistical packages have been developed in recent years and it has become easier to analyze nucleotide sequence data and gather subsequent information that would not normally be available. Multilocus sequence typing (MLST) is used for characterizing isolates of bacterial and fungal species and uses nucleotide sequences of internal fragments of housekeeping genes. This method is finding a place in clinical microbiology and public health by providing data for epidemiological surveillance and development of vaccine policy. It adds greatly to our knowledge of the genetic variation that can occur within a species and has therefore been used for studies of population biology. Analysis requires the detailed interpretation of nucleotide sequence data obtained from housekeeping and nonhousekeeping genes. This is due to the amount of data generated from nucleotide sequencing and the information generated from an array of analytical tools improves our understanding of bacterial pathogens. This can benefit public health interventions and the development of enhanced therapies and vaccines. This review concentrates on the analytical tools used in MLST and their use in the clinical microbiology and public health fields.</p
Artful living and the eradication of worry in Søren Kierkegaard's interpretation of Matthew 6:24-34
No full textDanish thinker Søren Kierkegaard published fourteen discourses, across four collections, on Matthew 6:24-34. The repeated readings of the biblical text, whose themes include the choice between God and mammon, worry, what it means to consider the birds and lilies, and how to seek first the kingdom of God, converge with Kierkegaard’s interest in anxiety, despair, worry, subjectivity, indirect communication, choice, the moment, and life before God. Accordingly, the discourses make connections with his larger works, elucidate frequently explored Kierkegaardian themes in recent scholarship, and contribute to his critique of nineteenth-century Copenhagen. Additionally, the collections present an interpretation of each verse and phrase of Matthew’s text and, held up against modern Matthew scholarship, they correlate with and contribute to Sermon on the Mount and New Testament studies. Kierkegaard’s reading of Matthew also holds implications for the practice of biblical interpretation as it promotes the importance of awareness of sin, interestedness, and appropriation as central to proper reading. His emphasis on Christ as the primary exemplar of Matthew’s text adds an additional Christological element to his hermeneutic. Furthermore, the discourses serve as spiritual treatises which provide the reader with theological terminology to help confront the problem of worry and suffering. In light of a human being’s distinctiveness as imago Dei, Kierkegaard elucidates ways an individual may respond artfully to the ongoing possibility of worry, a possibility which the discourses connect with Christian anthropology and external labels associated with possessions and status. The Matthew 6 discourses intimate Kierkegaard’s sympathy with classic Christian spirituality and, in combination with the cultural-ecclesiastical critique, the creative exegesis, and the in-depth analysis of the cause of and cure for worry, his work emerges as an excellent example of spiritual theology
Matthew’s Emmanuel Messiah: a paradigm of presence for god's people
No full textThe motif of divine presence is a clear phenomenon within the Gospel of Matthew. The modern critical means for assessing the ancient biblical text have multiplied to the point, some claim, of disparity. This study employs both narrative and redaction criticism in an attempt to respond authentically to the structural, historical and theological dimensions of Matthew's Gospel. This study begins with the presumption of the wholeness and integrity of Matthew's narrative, and assumes the gospel story to have an inherently dramatic structure which invites readers to inhabit imaginatively its narrative world and respond to its call. But since we are concerned with the role of both reader and author, this study also assumes a text with an historical author and context. The introduction focuses on the meta-critical dilemma facing New Testament students - what is the text and how do we read it? - and seeks some balance in terms of Krieger's analogy of the text as both window and mirror. Proposed is a narrative reading of Matthew's presence motif alongside a redaction critical assessment of it. In Chapter 2 the elements of narrative theory are introduced and relevant terms defined: the structure of narrative, the function of the narrator, points of view. Chapter 3 becomes an exercise in narrative reading, with Matthew's presence motif providing the focus, and the implied reader’s interaction with the story being predominant in interpretation. Characters, rhetorical devices, and points of view are discussed, to understand the motif's development throughout the story's progress. The thrust of Chapter 4 is thereafter to examine divine presence as a dominant motif within Matthew's most important literary context: the Jewish scriptures. Here the primary paradigms of divine presence provided by the Patriarchs, the Sinai experience, and the Davidic-Zion traditions are assessed. Chapter 5 follows with a more detailed examination of the OT "I am with you/God is with us" formula and its µeo' vµwv/ηuwv language, so strongly connected to Matthew's presence motif. Chapters 6-8 build on these investigations with a closer analysis of the three critical "presence passages" of Mt 1:23. 18:20 and 28:20. The passages and their contexts are probed from a redaction critical perspective, guided by the narrative investigation of Chapter 3, and the background from Chapters 4 and 5.The three major "presence passages" examined in Chapters 6-8 are also complimented by a number of secondary issues: worship, wisdom, the Spirit and the poor in Matthew, and their relation to Jesus' divine presence. These are discussed in Chapter 9. Chapter 10 summarizes and looks briefly at some implications. Matthew' presence motif proves to be an important element of the Gospel’s rhetorical design, redactional strategy and Christology. The presence of Jesus, the Emmanuel Messiah, exhibited in his risen authority, becomes the focus of his people's hopes and experiences in the post-Easter world. What the presence of Yahweh was to his people. Jesus now provides in a new paradigm for his people - his followers, the little ones, the poor and the marginalized, from all nations

Dorsal fin with 19–24 branched rays. Anal fin with 24–26 branched rays. Eye large (HL/ED ≤ 3.2, range = 2.9–3.2). Mouth very small (HL/MW ≤ 5.8, range = 4.7–5.8). Twelve teeth or fewer in the upper jaw (range = 7–12), 17 teeth or fewer in the lower jaw (range = 15–17). Pigmentation pattern subtle, including two components: (1) a pale dorsal black mark on each side of the body below the anterior base of the dorsal fin (under the second to sixth dorsal rays); (2) an ovoid mark, sometimes scarcely visible, at the base of the caudal fin, extending weakly onto the upper and lower lobes of the fin. EOD of normal polarity.</p> <p> <b>Description.</b> Morphometric ratios and meristic data are given in Table 3 for the holotype and paratypes separately. <i>Petrocephalus valentini</i> <b>n. sp.</b> is a small sized species within the genus (maximum SL = 77.2 mm, holotype). Body ovoid, longer than high (2.8 ≤ SL/H ≤ 3.0, paratype average = 2.9, holotype = 2.8) and laterally compressed. Head length between 3.4 and 3.7 times in standard length (paratype average = 3.6, holotype = 3.4). Snout short (6.5 ≤ HL/SNL ≤ 8.2, paratype average = 7.4, holotype = 6.5) and round. Mouth small (4.7 ≤ HL/MW ≤ 5.8, paratype average = 5.2, holotype = 5.1) and sub-terminal, positioned under the anterior half of the eye. Eye large (2.9 ≤ HL/ED ≤ 3.2, paratype average = 3.0, holotype = 3.1). Teeth small and bicuspid, 7–12 (paratype median = 9, holotype = 9) in a single row in the upper jaw, 15–17 (paratype median = 16, holotype = 17) in the lower jaw. Dorsal and anal fins originate in the posterior half of the body (1.6 ≤ SL/PDD ≤ 1.7 and SL/PAD = 1.6). Pre-dorsal distance approximately equal to the pre-anal distance. Dorsal fin with 19–24 branched rays (paratype median = 22, holotype = 22). Anal fin with 24–26 branched rays (paratype median = 25, holotype = 25). Scales cover the body, except for the head. Lateral line visible and complete with 35–36 pored scales along its length (paratype median = 36, holotype = 35). Nine to 12 scales (paratype median = 11, holotype = 11) between the anterior base of the anal fin and the lateral line. Caudal peduncle relatively thin (2.2 ≤ CPL/CPD ≤ 2.5, paratype average = 2.3, holotype = 2.3). Twelve scales around the caudal peduncle. Skin on head thick, turning opaque with formalin fixation. Knollenorgans clearly organized into two visible rosettes (the Augenrosette and the Nackenrosette). During our examination of specimens, we were uncertain about the definitive presence of the third rosette, the Kehlrosette, as this structure did not appear to us to be as distinct as it is in some other species (e.g., <i>P. binotatus</i>). Recently, however, more definitive analysis using toluidine blue staining of the skin suggests that the Kehlrosette is in fact present, but it is indeed smaller and harder to discern than in other <i>Petrocephalus</i> (M. Hollmann and B. A. Carlson, <i>unpub. obs.</i>).</p> <p>Holotype (m) Paratypes (n=8)</p> <p>Min–Max Mean Std–Dev Min–Max Median</p> <p>Meristic counts:</p> <p>Number of scale rows between the anterior base of the 11 9–12 11 anal fin and the lateral line (SDL)</p> <p> Number of teeth in the upper jaw (TUJ) 9 7–12 9 Number of teeth in the lower jaw (TLJ) 17 15–17 16 <b>Live coloration</b> (Fig. 5 A). Body uniformly white-silver, with two faint black patches, sometimes hardly distinguishable: (1) a dorsal mark on each side of the body, below the anterior base of the dorsal fin under the second to the sixth rays; (2) an ovoid/crescent-shaped mark centered at the base of the caudal fin (sometimes the center of this second mark is less distinguishable than the two arms of the crescent), with each arm slightly extending onto the upper and lower parts of the caudal fin. There is no melanin marking at the base of the pectoral fins. Fins translucent.</p> <p> <b>Distribution</b> (Fig. 1). Apparently endemic to the Congo basin. Common in Odzala National Park. At night, we collected single specimens cruising in the main channel of the Lékoli River. At the times we surveyed Odzala, <i>P. valentini</i> seemed absent from the small tributary creeks flowing through the park’s forest or savannah.

Matthew\u27s Vision: The Unity of the Formula Citations in Matt 1:1-4:16
No full textThe remote cause of this dissertation was a poorly written paper for a Romans seminar led by Dr. Carol Stockhausen in the Spring of 2002. In her comments below the bright red B at the end of my paper, Dr. Stockhausen remarked that the only reason the grade was not lower was that she charitably assumed I had completely misunderstood the assignment. This prompted a quest to understand Dr. Stockhausen\u27s work and eventually led me to read her dissertation, Moses\u27 Veil and the Glory of the New Covenant: The Exegetical Substructure of II Car. 3, 1-4, 6. The central insight of that work is in a certain respect simple, but extremely helpful: Paul interprets one biblical text by connecting it to another, and to recover Paul\u27s interpretation of those texts, we must retrace the links he saw (or created) between them. My next paper was an application of Dr. Stockhausen\u27s method to Romans I I, with gratifying results. That fall I participated in a seminar on the Gospel of Matthew led by Dr. Julian Hills. In a series of three papers, I explored the possibility of applying Dr. Stockhausen\u27s approach to a non-Pauline, narrative text. In the course of my research, I became aware that Matthew has taken a back seat in modern academic research: Luke is interesting because of his connection to Acts, Mark is interesting because he is earliest, and John is generally regarded as the most theologically profound of the gospels, but Matthew has no particular point in his favor. Indeed, one of his most distinguishing features, the frequent explicit citation of Scripture, is a favorite whipping boy among the commentators. Most literature on Matthew\u27s use of Scripture consists either of severe criticism or awkward excuses for its defects. At the same time, my work on the connections between Matthew\u27s citations led me increasingly to respect for the thoughtful way he engaged the biblical text. Respect gave way to wonder as I found that Matthew was in fact teaching me about Scripture, and wonder in turn yielded to joy as I contemplated the beauty of Matthew\u27s vision. Eventually I did find scholarship that points to the good in Matthew\u27s use of Scripture, especially the work of Dale C. Allison, but it still seemed that my own work had something to offer the academic community in presenting the scope and the unity of Matthew\u27s network of biblical citations and allusions. So was conceived the goal of this dissertation: without excuses for defects, to expose something of the grandeur of Matthew\u27s use of Scripture by research into the unity between his various biblical citations and allusions..

We examined 19 other specimens from Odzala National Park (specimen list provided in the section "additional material examined"). Diagnosis. Petrocephalus odzalaensis n. sp. is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics. Dorsal fin shorter than anal fin. Dorsal fin with a maximum of 22 branched rays (range = 20–22). Anal fin with a minimum of 27 branched rays (range = 27–29). Mouth sub-terminal; ratio between head length and mouth position is between 4.2 and 5.0. Eye small (3.7 ≤ HL/ED ≤ 4.2). Body pinkish-gray, darker dorsally, with the presence of three distinct pigmentation patches: (1) a distinct ovoid black mark situated below the anterior base of the dorsal fin on each side of the body; (2) a small black mark at the base of each pectoral fin; (3) an ovoid black mark on each side that is centered at the base of the caudal fin, not extending onto the upper and lower lobes of this fin. EOD of normal polarity, appearing triphasic at low gain, with two main phases and a small third phase. A final, fourth phase may be present, but it is always extremely small (<1.5 % of total peak-to-peak amplitude). Description. Morphometric ratios and meristic data for the holotype and paratypes are presented in Table 6. Petrocephalus odzalaensis n. sp. is a medium sized species within the genus (maximum SL observed = 99.3 mm; holotype = 92.9 mm). Body ovoid, longer than high (2.6 ≤ SL /H ≤ 2.9, paratype average = 2.8, holotype = 2.6) and laterally compressed. Head length between 3.7 and 4.0 times in standard length (paratype average = 3.9, holotype = 4.0). Snout short (6.2 ≤ HL/SNL ≤ 8.3, paratype average = 7.3, holotype = 6.6) and round. Mouth small (4.0 ≤ HL/MW ≤ 4.8, paratype average = 4.3, holotype = 4.3), sub-terminal, opening just under the anterior half of the eye. Teeth small and bicuspid, 8–12 in a single row in the upper jaw (paratype median = 11, holotype = 11), 18–23 in a single row in the lower jaw (paratype median = 20, holotype = 18). Dorsal and anal fins originate in the posterior half of the body (1.5 ≤ SL / PDD ≤ 1.6 and 1.6 ≤ SL /PAD ≤ 1.7, respectively). Pre-dorsal distance slightly greater than the pre–anal distance (1.0 ≤ PDD /PAD ≤ 1.1). Dorsal fin with 20–22 branched rays (paratype median = 21, holotype = 22). Anal fin with 27–29 branched rays (paratype median = 28, holotype = 29). Scales cover the body, except for the head. Lateral line visible and complete with 36–38 (holotype = 38) pored scales along its length. Ten to 14 scales (paratype average = 12, holotype = 11) between the anterior base of the anal fin and the lateral line. Caudal peduncle thin (1.9 ≤ CPL/ CPD ≤ 2.3, paratype average = 2.1, holotype = 2.1). Twelve scales around the caudal peduncle. Skin on head thick, turning opaque with formalin fixation. Knollenorgans clustered into the three distinct "rosettes" of Harder (1968). Live coloration (Fig. 8 A). Body background color pinkish-gray, darker dorsally. Pigmentation pattern consisting of three characteristic black patches: (1) a distinct ovoid black mark below the anterior base of the dorsal fin; (2) a small black mark at the base of the pectoral fin; and (3) an ovoid black mark centered at the base of the caudal fin, which does not extend onto the upper and lower lobes. Fins translucent. Distribution (Fig. 1). Endemic to the Congo basin. Abundant in Odzala. We collected P. odzalaensis n. sp. at several localities along the main course of the Lékoli River and in some small tributary creeks flowing through forest. Electric organ discharge (Fig. 8 C). The EOD waveform is typical for the genus, similar to EODs produced by many other Petrocephalus species. Total EOD duration ranges from 0.231 to 0.339 msec, based on 1.5 % voltage deviations from baseline relative to peak-peak amplitude. No EOD sex differences are apparent in the specimens recorded thus far. Lavoué et al. (2008) provide additional statistics for waveform landmarks and other EOD measurements. Histological examination confirms that electrocytes are type NPp (Lavoué et al., 2008). Remarks. Based on museum records from the Congo basin (pers. obs.), Petrocephalus odzalaensis has been misidentified as Petrocephalus simus in several instances. The latter species is endemic to the Lower Guinea province (Lavoué et al., 2004). Etymology. Named for Odzala National Park.Published as part of Lavoué, Sébastien, Sullivan, John P. & Arnegard, Matthew E., 2010, African weakly electric fishes of the genus Petrocephalus (Osteoglossomorpha: Mormyridae) of Odzala National Park, Republic of the Congo (Lékoli River, Congo River basin) with description of five new species, pp. 1-52 in Zootaxa 2600 on pages 22-25, DOI: 10.5281/zenodo.19758
