Peer Counselor Effectiveness in a Study Skills Course
No full textResearch has demonstrated the efficacy of attitudinal-motivational counseling in conjunction with study skills training. However, it has not been clear whether group or individual counseling was most beneficial. This research attempted to evaluate the usefulness of peer counselors in group and individual counseling sessions. Using students voluntarily enrolled in a study skills program, it was demonstrated that all students improved in study habit scores. However, only individual-peer counseling was effective in changing academic attitudes (p < . 05), as compared to group-peer counseling, no-counseling, and no-treatment conditions. Grade-point-average change scores were not differentially effected by the treatment conditions
Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Perspectives on Identity, Migration, and Displacement
No full textPerspectives on Identity, Migration, and Displacement -- edited by Steven Tötösy de Zepetnek, I-Chun Wang, and Hsiao-Yu Sun (Kaohsiung: National Sun Yat-sen University Press, 2010. ISBN 9789860235418 209 pages, bibliography, index) is a collection of articles about sociological and literary aspects of identity formation as a consequence of (im)migration. (Im)migration results in the problematics of assimilation and hybridity and in postcolonial scholarship, in particular, attention is paid to the concept of migration termed Creolization on the ground that cultural contact, cultural transmission, and cultural transformation result in the creation of new cultures.

Extensions to behavioral genetic programming
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2017.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (page 55).In this work I introduce genetic programming [5] as a general technique to produce programs with arbitrary behavior. I discuss genetic programming and its application the task of symbolic regression. I introduce behavioral genetic programming [6] as an extension to genetic programming and explore various extensions to it. The codebase that I build is made sufficiently flexible to easily accommodate future adaptions to the behavioral genetic programming methodology. I test the performance of the implementation of behavioral genetic programming along with several extensions.by Steven B. Fine.M. Eng

Pharmacokinetics of Genetically Engineered Antibody Forms Using Positron Emission Tomography
No full textIn the last grant period we have focused on multi-step targeting methodologies (MST), as a method for delivery of high dose to the tumor, with low dose to the bone marrow. We have explored uptake in colorectal, pancreatic and prostate cancer, using an special preparation, developed in collaboration with NeoRex A high tumor/bone marrow ratio is clearly achieved with MST, but with a cost, namely the higher dose to normal kidney. For this reason, we have in particular, (a) looked dosimetry for both tumor and normal organ, and especially renal dosimetry, which appears to be the target organ, for Y-90. (b) In parallel with this we have explored the dosimetry of very high dose rate radionuclides, including Holmium-166. (c) In addition, with NaiKong Cheung, we have developed a new MST construct based on the anti-GD2 targeting 5F11; (d) we have successfully completed development of s-factor tables for mice. In summary, renal dosimetry is dominated by about 4-5% of the injected dose being held long-term in the renal cortex, probably in the proximal tubule, due to the universal uptake of small proteins. This appears to be a function of a biotynlated protein binding of the strept-avidin construct, to HSP70. This cortical uptake has caused us to reconsider renal dosimetry as a whole, with the smaller mass of the cortex, rather than the whole kidney, as the target organ. These insights into dosimetry will be of great importance as MST, becomes more common in clinical practice

Pronotum (Fig. 83) provided with a very fine puncture; usually slightly transverse, and sub-cordiform, sometimes subcircular or sub-elliptical and more transverse, with the base straight or sub-straight, not sinuous before the posterior angles and generally something narrower than the apex. Elongated and medially depressed prosternal apophysis (Fig. 119), surpassing the level of the procoxae. Elytra oval elongated, variable in length, subcylindrical, sometimes slightly striated and somewhat broader than the pronotum. Small aedeagus, fusiform parameres and barely longer than phallobase (Fig. 167).</p> <p> <b>Comments</b>: Species described from “Lusitania”, not from Andalusia as Viñolas & Catagena (2005) mentioned. Steven (1828) described <i>Tentyria platyceps</i> with at least one specimen from “Lusitania” (MNHUB). Data on the Steven’s description agrees with the label that carries one of the syntypes listed as <i>T. curculionoides</i> Herbst in the Berlin Museum, before to be rectified and attributed to “ <i>T. curculioides</i> Ht. *” (Fig. 231). This confusion is the reason of that the type of <i>T. platyceps</i> Steven has remained hidden to date, not appearing in the recording book of the Museum.</p> <p> Accordingly, <i>T. platyceps</i> Steven was an unknown species to Solier (1835) and Rosenhauer (1856). Hence these authors described <i>T. goudoti</i> Solier (Fig. 232) and <i>T. modesta</i> Rosenhauer (Fig. 233), with identical characters those of <i>T. platyceps</i> Steven, as indicated Kraatz (1865) and Schaum (1862) respectively. This verifies that these last authors knew the true identity of <i>T. platyceps</i> Steven, by intuiting the confusion between <i>T. curta</i> Steven and <i>T. curculionoides</i> Herbst (Kraatz 1865). From Kraatz (1865), <i>T. platyceps</i> Steven has been a species correctly interpreted by almost all authors.</p> <p> Reitter (1900), described <i>T. calcarata</i> from Malaga, which was, dubiously, considered synonymy of <i>T. platyceps</i> Steven by Español (1960), since it was the unique species of <i>Tentyria</i> present in the mentioned locality whose description fits to that Reitter gave, even when this author does not include it in the group 3, close to <i>T. platyceps</i> Steven.</p> <p> Later, Kaszab designated in litt. “ Holotypus ” of <i>T. calcarata</i> Reitter a specimen from the MNHN labelled from Malaga (Fig. 234), and which corresponds to a variant specimen of the <i>T. platyceps</i> Steven (with the pronotum very transverse, and sub-elliptical), like the syntypes of <i>Tentyria platyceps</i> v. <i>modesta</i> Rosenhauer.</p> <p> <b> Designation of the Lectotype <i>Tentyria platyceps</i> Steven, 1828, present designation</b> :</p> <p> The specimen of the typical series that bears the following labels (two of them old): small rectangular label, “45574” / big square label, “ <i>Orbiculata Akis</i> F., <i>curculioides</i> Ht. *, <i>Ten.

The specimen that bears the following labels: “ <i>T. platyceps</i> v. <i>modesta</i> Rosh. Hispania / <i>T. platyceps</i> v. <i>modesta</i> Rosh. / Hispania Rosh.”, is designated Lectotype (Fig. 233); the other that carrying the label: “Hispania Rosh.”, is designated Paralectotype.</p> <p> <b>Geographical distribution:</b> Widely distributed in central and southern Iberian Peninsula, especially in the inner areas. <i>T. platyceps</i> Steven, has been also cited in the north of Morocco (Tánger) as <i>T. goudoti</i> Solier (1835), Escalera (1914) and Kocher (1958).

Is the debt crisis history? Recent private capital inflows to developing countries
No full textThe outlook for economic development for an important group of middle-income countries has again been buoyed by substantial private capital inflows in the 1990s. As in the 1970s, this development has been met with cautious optimism. It is generally accepted that these countries need resource transfers from the rest of the world to support capital formation and growth. It is also generally accepted that these private capital flows make the allocation of resources more efficient. But there is concern that a rapid reversal of market sentiment could impose considerable adjustment costs on these same economies. The authors try to quantify what many consider to be the main reasons debtor countries have access to capital markets again: (a) Domestic policy reform in the debtor countries. (b) Debt and debt service reduction, usually associated with Brady Plan restructuring. (c) Changes in the external market, such as changes in interest rates in industrial countries. They argue that a useful barometer for access to new loans is the market value of existing sovereign debt. It follows that a quantitative analysis of the factors that caused the market value of sovereign debts to rise rapidly after 1989 would also improve understanding of the forces behind the renewed access to international capital. Empirical historical evidence suggests that fiscal reform, privatization, and debt reduction are useful in explaining relative improvements in the standing of debtor countries in international credit markets. Debtor countries with strong reform programs, in other words, are better prepared to withstand deterioration in the external environment. But the reduction in dollar interest rates since 1989 appears to be the chief factor in the debtor countries'renewed access to international loans. The authors estimate the effect of increases in dollar interest rates and conclude that the typical debtor country remains vulnerable to increases in interest rates that are well within the range of recent experience.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Strategic Debt Management,Financial Intermediation

Motivation and background
Manual evaluation of a sperm sample using a microscope is time-consuming and requires costly experts who have extensive training. In addition, the validity of manual sperm analysis becomes unreliable due to limited reproducibility and high inter-personnel variations due to the complexity of tracking, identifying, and counting sperms in fresh samples. The existing computer-aided sperm analyzer systems are not working well enough for application in a real clinical setting due to unreliability caused by the consistency of the semen sample. Therefore, we need to research new methods for automated sperm analysis.
Target group
The task is of interest to researchers in the areas of machine learning (classification and detection), visual content analysis, and multimodal fusion. Overall, this task is intended to encourage the multimedia community to help improve the health care system through the application of their knowledge and methods to reach the next level of computer and multimedia-assisted diagnosis, detection, and interpretation.
