Parameters Calculation

The rigging parameters calculation for midwater trawls are discussed with description of numerical model for calculating the parameters of trawl boards, hydrodynamic kites, and dispersed and concentrated weights which provide the designed values of horizontal and vertical opening of the trawl mouth. A distinctive feature of the proposed technique is a systematic approach: the trawl, trawl boards, and wires are considered as a joint complex.

Asymptotic methods are used to explore the role of one of the homogeneous chemical reactions, water protolysis, in a recent numerical model for the electrochemical pickling of steel. The analysis helps to interpret the somewhat surprising results of the original numerical model: that the local current density profile at the pickled strip does not depend on whether the water protolysis reaction is included in the model or not. The analysis also gives a useful systematic approach for determining qualitative estimates for the width of reaction boundary layers at cell electrodes, which can be of help when designing a computational mesh for the numerical solution of electrochemical models that have such layers.

Summary This article attempts to give a summary of the contribution made by early Arabs and Muslims in the field of phonetic sciences. Works by scholars like al-Khalīl (d.175/791), Sībawayhi (d.177/793), Ibn Jinnī (d.392/1002), Ibn Sīnā or Avicenne (d.428/1037) and others will be given special attention in this connection. In particular, it presents the various treatments of the Arabic nasal sounds and the phenomenon of nasalization. As a term of reference, the Arab and Muslim phoneticians divided the Arabic phonemes into categories such as: glottals, pharyngeals, palatals, dentals /l, r, n/, and labials /f, b, m, w/. Al-Khalīl is one of the first Arab phoneticians to order the Arabic phonemes in terms of place of articulation along the vocal tract from the glottis upward to the lips. His student, Sībawayhi, and later phoneticians also recognized other categories in terms of manner of articulation such as: voiced/voiceless, stop/ non-stop, rolled, lateral, nasals/m, n/, including variants, e.g. [ŋ, N]. Further, Sībawayhi and Ibn Jinnī seem to lay more emphasis on treating ghunna or nasality and other features in terms of binary distinctive feature analysis. The Muslim phoneticians also recognized that in certain contexts /n/ and /m/ may influence non-nasals, both vowels and consonants. In sum, a close look at the early Arab grammatical works reveals an underlying systematic approach and a rich mine of terminology which are relevant both to modern Arabic phonetics and general phonetics. Some instrumental (spectographic and mingo-graphic) data are included at the end of the article in order to support some of the descriptive techniques used in early phonetic heritage.

Students with persistent reading difficulties are often especially challenged by multisyllabic words; they tend to have neither a systematic approach for reading these words nor the confidence to persevere (Archer, Gleason, & Vachon, 2003; Carlisle & Katz, 2006; Moats, 1998). This challenge is magnified by the fact that the vast majority of English words are multisyllabic and constitute an increasingly large proportion of the words in elementary school texts beginning as early as grade 3 (Hiebert, Martin, & Menon, 2005; Kerns et al., 2016). Multisyllabic words are more difficult to read simply because they are long, posing challenges for working memory capacity. In addition, syllable boundaries, word stress, vowel pronunciation ambiguities, less predictable grapheme-phoneme correspondences, and morphological complexity all contribute to long words' difficulty. Research suggests that explicit instruction in both syllabification and morphological knowledge improve poor readers' multisyllabic word reading accuracy; several examples of instructional programs involving one or both of these elements are provided.

Psychoanalytically Oriented Psychotherapy

Abstract. Assessing change during long-term psychotherapy can be a challenging and uncertain task. Psychological assessments can be a valuable tool and can offer a perspective from outside the therapy dyad, independent of the powerful and distorting influences of transference and countertransference. Subtle structural changes that may not yet have manifested behaviorally can also be assessed. However, it can be difficult to find a balance between a rigorous, systematic approach to data, while also allowing for the richness of the patient’s internal world to emerge. In this article, the authors discuss a primarily qualitative approach to the data and demonstrate the ways in which this kind of approach can deepen the understanding of the more subtle or complex changes a particular patient is undergoing while in treatment, as well as provide more detail about the nature of an individual’s internal world. The authors also outline several developmental frameworks that focus on the ways a patient constructs their reality and can guide the interpretation of qualitative data. The authors then analyze testing data from a patient in long-term psychoanalytically oriented psychotherapy in order to demonstrate an approach to data analysis and to show an example of how change can unfold over long-term treatments.
