Purpose: To investigate the attitudes, beliefs, and concerns of pregnant and postpartum adolescents regarding breastfeeding. Study Design and Methods: Audiotaped focus groups of low-income, largely minority pregnant and postpartum adolescents were conducted and transcripts analyzed using content analysis techniques. Findings: Major themes identified were in the area of beliefs, such as They say it's healthy, or It hurts; attitudes, such as breastfeeding is the mother's choice and The baby comes first; and concerns such as privacy, and Breastfeeding leads to dependency. Clinical Implications: Adolescents can be encouraged to breastfeed, but require appropriate education beyond what they have heard from others. Myths such as pain during breastfeeding need to be addressed. Since teens want to learn but not be told what to do, active learning strategies such as guided Internet searches could be helpful to guide them into discovery of the benefits of breastfeeding. Since all the teens in this study felt that the baby comes first, emphasizing the benefits of breastfeeding for the baby should predominate educational efforts. Concerns related to physical exposure while breastfeeding can be addressed antenatally through discussing creative strategies to maintain modesty. This study suggests that, in the postpartum hospital setting, adopting a sensitive, initially hands-off' approach to supporting breastfeeding might be more well-accepted than tactile assistance, and that following the initial establishment of a milk supply, various levels of breastfeeding exclusivity should be considered as potentially acceptable infant feeding patterns.

Purpose: The purpose of this qualitative descriptive study was to explore the medication-taking experiences of undergraduate college students prescribed short-term antibiotic therapies and to describe factors influencing their adherence. Data sources: Thirty-four undergraduate students prescribed antibiotics for treatment of an acute infectious illness at a large university health center were recruited to participate in this study. Semistructured telephone interviews were conducted after students finished their course of treatment. Qualitative descriptive content analysis was used to analyze the transcripts typed from the audio-taped phone interviews. Conclusions: The main theme that emerged from the data was antibiotic-taking self-management. Most participants were able to adapt medication regimens into their daily routines, and used events in their day and specific reminder strategies to help them to remember to take their medications. This occurred despite an ever-changing class and work schedule and being prescribed complex, lengthy antibiotic regimens. Most dosing errors occurred during times when schedules changed or students were off campus during weekends or college breaks. A small number of students discontinued therapy early because of side effects or forgetfulness. Implications for practice: By understanding factors that influence antibiotic adherence from a college student perspective, healthcare providers can suggest strategies to promote adherence that are tailored to the specific needs of this unique population. © 2006 American Academy of Nurse Practitioners.

In this paper we propose novel algorithms for reconfiguring modular robots that are composed of n atoms. Each atom has the shape of a unit cube and can expand/contract each face by half a unit, as well as attach to or detach from faces of neighboring atoms. For universal reconfiguration, atoms must be arranged in 2×2×2 modules. We respect certain physical constraints: each atom reaches at most unit velocity and (via expansion) can displace at most one other atom. We require that one of the atoms can store a map of the target configuration. Our algorithms involve a total of O(n 2) such atom operations, which are performed in O(n) parallel steps. This improves on previous reconfiguration algorithms, which either use O(n 2) parallel steps [8,10,4] or do not respect the constraints mentioned above [1]. In fact, in the setting considered, our algorithms are optimal, in the sense that certain reconfigurations require Ω(n) parallel steps. A further advantage of our algorithms is that reconfiguration can take place within the union of the source and target configurations. © 2009 Springer-Verlag.

This paper considers the following conjecture: If R is an unmixed, equidimensionallocal ring that is a homomorphic image of a Cohen-Macaulay local ring, then for any ideal J generated by a system of parameters, the Chern coefficient e1(J) < 0 is equivalent to R being non Cohen-Macaulay. The conjecture is established if R is a homomorphic image of a Gorenstein ring, and for all universally catenary integral domains containing fields. Criteria for the detection of Cohen-Macaulayness in equi-generated graded modules are derived. © International Press 2009.

The problem of motivation has received a great deal of attention, and many successful approaches have been developed. However, in areas such as introductory college mathematics, students often question their own potential for success. At the first sign of trouble, their fears are confirmed and many of them drop out, formally or informally. If a method could be found to improve persistence, motivational techniques would have an opportunity to succeed. In this article, the author describes a simple method to improve persistence using assessments that are normally already in place. Data are presented indicating that the method improves persistence and achievement. © 2009, Copyright Taylor & Francis Group, LLC.

We study birational maps with empty base locus defined by almost complete intersection ideals. Birationality is shown to be expressed by the equality of two Chern numbers. We provide a relatively effective method for their calculation in terms of certain Hilbert coefficients. In dimension 2 the structure of the irreducible ideals-always complete intersections by a classical theorem of Serre-leads by a natural approach to the calculation of Sylvester determinants. We introduce a computer-assisted method (with a minimal intervention by the computer) which succeeds, in degree ≤5, in producing the full sets of equations of the ideals. In the process, it answers affirmatively some questions raised by Cox [Cox, D.A., 2006. Four conjectures: Two for the moving curve ideal and two for the Bezoutian.

Given a convex polyhedron with n vertices and F faces, what is the fewest number of pieces, each of which unfolds to a simple polygon, into which it may be cut by slices along edges? Shephard's conjecture says that this number is always 1, but it's still open. The fewest nets problem asks to provide upper bounds for the number of pieces in terms of n and/or F. We improve the previous best known bound of F/2 by proving that every convex polyhedron can be unfolded into no more than 3F/8 non-overlapping nets. If the polyhedron is triangulated, the upper bound we obtain is 4F/11.

Core constructs are necessary as a basis for scale development in brand prestige research. This study examines the theoretical rationale for two such concepts - brand excellence and status conferral - and uses latent class scaling in an empirical test as to whether they are both important independent dimensions of prestige brands. Based on the analysis, these concepts are shown to be consistently present for two brands in two diverse product categories. The research calls into question earlier work on the measurement of brand prestige that was premised on a one-dimensional concept of prestige. Further studies are needed to explore the dimensionality and substantive structure of the brand prestige concept, to confirm or disconfirm findings from this research. © 2009 IOS Press.

Purpose: The purpose of this paper is to provide a methodology by which qualitative analyses serve as rich source materials for discovery of theoretically cogent interrelations between latent variables. Design/methodology/approach: In an illustrative case, qualitative data are collected from US franchisee managers from a single branded franchise of automotive repair outlets. Qualitative analysis of franchisee experiences and attitudes is critical for construction of a causal model used to predict conflict intensity between franchisee managers and franchisors. Findings: The model is based on franchisees' normative expectations for resource allocation within the franchise; and their perceptions of franchisor normative violations, which are determinative of grievances, distrust, and hostility. This theoretical orientation serves to generate a system of interrelated empirically testable propositions. Research limitations/implications: In principle, the primary limitation of using qualitative analysis for the construction of causal models is the fruitfulness of the theoretical orientation shared by the qualitative analyst and the causal modeler. Practical implications: The methodological approach advanced in this paper advances qualitative research and causal modeling beyond the individual contributions. Qualitative analysis infuses variables and process imagery into causal modeling. In turn, causal modeling elaborates the qualitative analysis and makes explicit logical connections between variables. Originality/value: This paper advances a methodology by which qualitative analysis and causal model construction may be usefully integrated. Theory-based qualitative analysis may be formalized to map latent concepts and their interrelations. Further, operational measures of these concepts may be adduced from the analysis of textual data. © Emerald Group Publishing Limited.

This research examines the four culture dimensions developed by Hofstede's 1980 and 1983 studies exploring the potential of management-employee conflict. In the present study, employee responses to Hofstede's national culture survey were performed in Belarus, formerly of the Soviet Union, in order to establish a culture score for each of Hofstede's four culture dimensions in a centrally planned economy. The results of the research run counter to some of the stereotypic cultural characteristic expectations, and support others of the cultural values attributable to the Republic of Belarus, an autocratic political and economic state in Eastern Europe.

Professors in management and business are encouraged to incorporate critical thinking as an objective in their courses. "The Lobster Tale" provides an opportunity to engage students in various levels of critical thinking, ranging from a relatively superficial reading to an examination of the deeper, often hidden issues. Using the foundations of critical theory and systems theory, the story draws on economics, social theory, philosophy, and other disciplines to present a simplified version of the complexities found in our global environment. It can be used to supplement a variety of courses in the business curriculum and to encourage students to challenge not only assumptions but also conventional wisdom and, perhaps, knowledge itself. © 2009 The Author(s).

This article presents a pedagogical model that utilizes students as primary researchers in the identification, interviewing, and then reporting on women entrepreneurs as a major component of a multidisciplinary entrepreneurship course. The purpose of the course is to attract students who may not be familiar with the entrepreneurship concept itself, the role of women in such economic ventures, or the possibilities for people like themselves in such a career avenue. Students are exposed to the accomplishments of women entrepreneurs throughout U.S. history in the broad categories of agriculture and mining; construction; communication; manufacturing; service (both for profit and not-for-profit); transportation; and wholesale and retail trade. This content experience is then enhanced by the studentsʼ own direct interaction with and interviewing of women entrepreneurs. The implementation, potential outcomes, and possible adaptations of the course are described, and this transformational learning process model is illustrated. © Published by DigitalCommons©SHU, 2006.
