What’s in a Bot? L2 Lexical Development Mediated through ICALL  [PDF]
Kelly Arispe
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.41013
Abstract:

In recent years, the field of Second Language Acquisition (SLA) has made great strides to refocus its attention on the essential role that vocabulary plays in becoming a proficient L2 learner (Nation, 2001). Moreover, Computer Assisted Language Learning (CALL) has made advances in providing interactive online tools that help L2 learners strategically engage and work through their vocabulary development. This present study reports on how an Intelligent CALL tool (ICALL), Langbot, helps learners at the beginner and intermediate levels with their lexical acquisition. Modeled after instant messaging systems, which create a synchronous communicative environment, Langbot acts like a pedagogical scaffold or online buddy that caters to the vocabulary needs of each individual learner. It provides 1) translation requests with examples in context, 2) a frequency-based “word of the day” and 3) quizzes based on recent inquiries and a specific frequency range according to the learner’s level. The results from breadth and depth tests (N = 142), suggest that learners at all levels that have access to Langbot significantly improve their vocabulary breadth, while only intermediate-high learners with access to Langbot improve their vocabulary depth. Furthermore, survey data demonstrate Langbot’s effectiveness and accessibility based on learner perceptions.

Investigating the Suitability of Agile Methods for Requirements Development of Home Care Systems  [PDF]
Sandra Kelly, Frank Keenan
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.39104
Abstract: The ageing population in developed countries brings many benefits but also many challenges, particularly in terms of the development of appropriate technology to support their ability to remain in their own home environment. One particular challenge reported for such Home Care Systems (HCS) is the identification of an appropriate requirements development technique for dealing with the typical diverse stakeholders involved. Agile Methods (AMs) recognize this challenge and propose techniques that could be useful. This paper examines the desirable characteristics identified for requirements development in HCS and investigates the extent to which agile practices conform to these. It also sets out future work to improve the situation for the non compliant points found.
A longitudinal study of the professional dispositions of teacher candidates  [PDF]
Arlene Ignico, Kelly Gammon
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.22014
Abstract: The purpose of this study was to examine the professional disposition scores of Physical Education teacher candidates over time. In ad-dition, differences between teacher and student ratings were investigated. Participants were 65 students who completed three methods courses (A, B, and C) across a two-year period. Both the teacher and the students completed a profes-sional dispositions instrument in each of the three classes. Results indicated a decrease in disposition self ratings and teacher ratings over time. A 2 (Rater) x 3 (Time) ANOVA revealed that the student and teacher ratings were different for classes A and B but not for class C. The findings are encouraging in light of the strong alignment between teacher and student ratings in the upper-level class. The dispositions in-strument appears to be a valid and reliable method to assess the professional behaviors of teacher candidates.
Where Science Meets Art: Sociology and Social Work  [PDF]
Stephanie Kelly, Tony Stanley
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.24044
Abstract: The nexus of neo-liberalist influences in our current risk society has produced a crisis for both New Zealand sociology and Social Work, playing out in practice domains and in the academy. This paper argues that by co-habituating and co-operating, we may have a tangible way forward. One of the biggest challenges for Social Work practitioners is to come to terms with the role of theory in the practice of their discipline—a discipline that is often fast-paced, but increasingly focused on dealing with one client at a time, and often reduced to a dyad emphasis in practise: that of client and worker. One of the biggest challenges for the sociologist embarking on a career in research is to come to terms with sociology as methodological toolkit for social activism where knowledge of theory can be applied toward sustained societal change. Both offer a methodological approach to understanding the human condition in context. Both disciplines are at risk because of neo-liberalisation, and this, we argue must be avoided by a move toward each other.
Skin-Sparing Mastectomy: An Update for Clinical Practice  [PDF]
Kelly Lambert, Kefah Mokbel
Surgical Science (SS) , 2013, DOI: 10.4236/ss.2013.41010
Abstract:

Aim: To review the oncological safety and aesthetic advantage of skin-sparing mastectomy (SSM) for invasive breast cancer (IBC) and ductal carcinoma in-situ (DCIS). Controversies including the impact of radiotherapy (RT) on immediate breast reconstruction (IBR), preservation of the nipple-areola complex (NAC) and the role of endoscopic mastectomy are also considered. Methods: Literature review using Medline and PubMed. Results: SSM is safe in selected cases; including IBC < 5 cm, multi-centric tumours, DCIS and for risk-reduction surgery. Inflammatory breast cancers and tumours with extensive involvement of the skin represent contra-indications to SSM due to an unacceptable risk of local recurrence. SSM can facilitate IBR and is associated with an excellent aesthetic result. Prior breast irradiation or the need for post-mastectomy radiotherapy (PMRT) do not preclude SSM, however the cosmetic outcome may be adversely affected. Nipple/areola preservation is safe for peripherally located node negative tumours. A frozen section protocol for the retro-areolar tissue should be considered in these cases. The advent of acellular tissue matrix systems has widened the applicability of implant-based immediate reconstruction following SSM. Data on endoscopic mastectomy is limited and superiority over conventional SSM has not been demonstrated. Conclusion: SSM is safe in selected cases and is associated with advantages over simple mastectomy, including a superior aesthetic outcome and a potential reduction in the number of reconstructive procedures per patient.

Anesthetic Management of a Patient with Hermansky-Pudlak Syndrome  [PDF]
Kelly Zach, Lopa Misra
Open Journal of Anesthesiology (OJAnes) , 2015, DOI: 10.4236/ojanes.2015.52007
Abstract: Hermansky-Pudlak Syndrome (HPS) is a rare genetic condition characterized by platelet function abnormalities and oculocutaneous albinism. Other systemic manifestations of the disease include pulmonary fibrosis, granulomatous colitis, impaired renal function, and cardiomyopathy. Due to the systemic extent of the disease, HPS has multiple anesthetic concerns and requires a detailed preoperative evaluation and close perioperative monitoring.

Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2015, DOI: 10.4236/ojra.2015.53013
Abstract: Anti-RNA Polymerase III has been recognized as an important autoantibody in Systemic Sclerosis and it is now included in the 2013 ACR/EULAR classification criteria for Systemic Sclerosis. With this manuscript we attempt to review the current data on anti-RNA polymerase II as it relates to Systemic Sclerosis.
Pleural drainage: an evolving area
Martin Kelly
Critical Care , 2004, DOI: 10.1186/cc2458
Abstract: Our unit has also achieved good success using 12-French guage drains inserted using a Seldinger technique (Thal-Quick Chest Tubes, Cook Critical Care, Bloomington, IN, USA) in patients on a respiratory ward. They seem to be patient-friendly with little initial morbidity. However, it has been noted that blockage by fibrinous or clotted material does occur. I am surprised that the authors did not encounter this problem, even with the larger drain.I note the comments on the use of ultrasound guidance to access the pleural space. A recent article [3] reported increased efficacy using ultrasound guidance in the hands of an interventional radiologist, performing the procedure in 'real time'. This seems a useful method but it is a luxury that is often not available. The use of ultrasound to locate the most suitable position for access, using an 'X marks the spot' methodology, has in our experience often been unreliable. I suspect that this is because the pleural access is not performed in 'real time'. I would be interested to know the authors' thoughts on this and whether any of their catheters were inserted using ultrasound guidance.I would urge caution on behalf of Singh and coworkers in interpreting some of the data. This is a highly selected, small group of patients. In this setting, the absence of infection or blockage is probably of limited value. Our experience has revealed that there are definite, although low, rates of blockage and infection. A larger, prospective, 'real world' study is needed.Nonetheless, research in this area is always welcome, and the study is of interest to respiratory physicians as well as intensivists.None declared.
To quell obesity, who should regulate food marketing to children?
Ben Kelly
Globalization and Health , 2005, DOI: 10.1186/1744-8603-1-9
Abstract: United States businesses have been unsurpassed leaders in proliferating the availability, marketing and consumption of high-energy, low-nutrition foods at home and around the world. Their aggressive, high-priced marketing of those foods has especially targeted children – the adult consumers of the future in whom the early creation of brand and product commitment is, in the eyes and ledgers of some huge corporations, essential to profitability.But the leadership in so-called "junk food" promotion has not been matched in the U.S. by effective regulatory controls to prevent marketing abuses of children. Advertising of such products has been misleading, overblown, and seemingly bent on undermining the ability of parents to moderate their children's eating practices. Although still concentrated in television viewing hours directed at child entertainment and publications read by children, it is spreading rapidly to other means of messaging, among them online games ("advergames"), product placements in films and television shows, and product-linked websites.The position of the driving-force industries – food marketers and advertising agencies – presents an interesting internal contradiction. On one hand they assert valid evidence is lacking that exposure to such messages actually influences the consumption practices of children, let alone contributes to health problems such as obesity. On the other they claim that abusive child-directed marketing is being effectively and adequately controlled by an industry-sponsored system of self-regulation. Health advocates, meanwhile, are increasingly urging that the government intervene by legislating and enforcing objective standards over and above any that the industry imposes or claims to impose.The regulatory agency that would set and implement such standards is the U.S. Federal Trade Commission (FTC), but at present it contends it cannot do so without additional statutory authority.

Development and implementation of an herbal and natural product elective in undergraduate medical education
Kelly Karpa
BMC Complementary and Alternative Medicine , 2012, DOI: 10.1186/1472-6882-12-57
Abstract: Knowledge outcomes were evaluated via administration of a pre- and post-course test (paired student t-test). End-of-course evaluations (Likert-type questions and narrative responses) were used to assess student opinion of knowledge and skills imparted by the elective and overall course content (mean, standard deviation).Over three academic years, 23 students have enrolled in this elective. More than 60% of participants have been female and nearly half of the students (43%) have pursued residencies in primary care. Completion of the course significantly increased student knowledge of common herbal/natural product mechanisms, uses, adverse effects, and drug-interactions as determined by a pre- and post-course knowledge assessment (45%?±?10% versus 78%?±?6%; p?<?0.0001). The course was highly rated by enrollees (overall course quality, 4.6 of 5.0?±?0.48) who appreciated the variety of activities to which they were exposed and the open classroom discussions that resulted. While students tended to view some alternative medical systems with skepticism, they still believed it was valuable to learn what these modalities encompass.Development and implementation of a herbal/natural product elective that engages undergraduate medical students through active learning mechanisms and critical analysis of the literature has proven effective in increasing knowledge outcomes and is deemed to be a valuable curricular addition by student participants. In the future, it will be of interest to explore mechanisms for expanding the course to reach a larger number of students within the time, financial, and logistical constraints that currently exist.Complementary and alternative medicine (CAM) disciplines are diverse medical and health care systems, practices, and products that are not part of conventional medicine. Three hundred distinct CAM modalities have been identified, including at least 20,000 herbal products that are available for consumer use [1]. In the United States, 38% of adu
