Wanted: an efficient and user friendly library catalogue
Jerry D. Saye,Alenka ?auperl
Knji?nica : Revija za Podro?je Bibliotekarstva in Informacijske Znanosti , 2002,
Abstract: Many people find great challenges in using library catalogues. Current OPACs have developed from the traditional card catalogue structure while the MARC formats have primarily provided coding conventions for the traditional bibliographic description.Cataloguers invest significant effort in preparing catalogue records. Yet some studies show that the product of their work is not as useful as it could be. OPACs and their users efficiently use only a fraction of data present in catalogue records. We will explore which parts of the catalogue record are useful and which are not. We will analyze how an alternative catalogue record, based on Functional Requirements for Bibliographic Records, would aid in maximizing the catalogue record’s usefulness.
Roles for estrogen and progesterone in breast cancer prevention
D Joseph Jerry
Breast Cancer Research , 2007, DOI: 10.1186/bcr1659
Abstract: Estrogen and progesterone play leading roles in orchestrating proper development and function of breast tissue. High levels of these hormones are associated with pregnancy and appear to be responsible for the diminished risk for breast cancer among women following a full-term pregnancy. Exogenous estrogen and progesterone are sufficient to mimic the protective effects of parity and suppress mammary tumors in rodents exposed to the carcinogen dimethylbenz(α)anthracene (DMBA). However, the relevance of these results has been debated because the relationship between polyaromatic hydrocarbons and the oncogenic events observed in breast cancers remain unclear.To address this, investigators from the laboratories of Rajkumar and Medina [1] have examined the effects of exogenous estrogen and progesterone in mouse models that bear lesions in clinically relevant pathways. Because over-expression of the HER2/neu oncogene is observed in up to 30% of breast cancers, responses to treatment with estrogen and progesterone were analyzed in mice overexpressing HER2/neu (MMTV-neu mice). Exogenous estrogen and progesterone reduced the incidence of mammary tumors in these mice by more than 60%. The p53 tumor suppressor pathway is also commonly disrupted in breast cancers. Mice bearing mammary epithelial transplants that have homozygous deletions in the mouse p53 gene (Trp53-/-) provide a model for loss of p53. When exogenous hormones were administered to mice just after puberty (age 5 to 7 weeks), the incidence of tumors in Trp53-/- mammary tissues was reduced by at least 70%. The protective effect was preserved even when estrogen and progesterone were administered to older mice (age 23 to 25 weeks), indicating that the timing of treatments was not critical. The exogenous hormones did not affect development of preneoplastic lesions but rather prevented their apparent progression to tumors. Together, the experiments demonstrate that a 14-day treatment with exogenous estrogen and progeste

Health care logistics: who has the ball during disaster?
Jerry D. VanVactor
Emerging Health Threats Journal , 2011, DOI: 10.3402/ehtj.v4i0.7167
Abstract: In contemporary organizations, a wide gamut of options is available for sustaining and supporting health care operations. When disaster strikes, despite having tenable plans for routine replenishment and operations, many organizations find themselves ill-prepared, ill-equipped, and without effective mechanisms in place to sustain operations during the immediate aftermath of a crisis. Health care operations can be abruptly halted due to the non-availability of supply.The purpose of this work is to add to a necessary, growing body of works related specifically to health care logistics preparedness and disaster mitigation. Logistics management is a specialized genre of expertise within the health care industry and is largely contributive to the success or failure of health care organizations. Logistics management requires extensive collaboration among multiple stakeholders—internal and external to an organization. Effective processes and procedures can be largely contributive to the success or failure of organizational operations. This article contributes to the closure of an obvious gap in professional and academic literature related to disaster health care logistics management and provides timely insight into a potential problem for leaders industry-wide.One critical aspect of disaster planning is regard for competent logistics management and the effective provision of necessary items when they are needed most. In many communities, there seems to be little evidence available regarding health care logistics involvement in disaster planning; at times, evidence of planning efforts perceptibly end at intra-organizational doors within facilities. Strategic planners are being continually reminded that health care organizations serve a principal role in emergency preparedness planning and must be prepared to fulfill the associated possibilities without notification. The concern is that not enough attention is being paid to repeated lessons being observed in disasters and emergency events.
Mapping the EQ-5D-5L Utility Scores: A Pilot Study in Orthopaedic Patients  [PDF]

Open Journal of Orthopedics (OJO) , 2015, DOI: 10.4236/ojo.2015.54010
Abstract: Objective: The purpose of this study is to investigate whether the LE CAT, PROMIS PF CAT, Depression CAT, or Pain CAT can be used as a proxy for the EQ-5D-5L. Background: Patient-reported out-come measures have become vital tools for physicians to understand the effectiveness and value of treatment and care. Methods: This study was conducted in 2012 with 116 patients that took the EQ-5D-5L and a number of patient-reported outcome instruments in a university orthopaedic clinic. Regression analyses were conducted to predict EQ-5D-5L index scores from the LE CAT, PROMIS PF CAT, Depression CAT, and Pain CAT. Results: All predictors, separately or combined, significantly predicted the EQ-5D-5L index scores (p < 0.0001). The LE CAT was the best predictor; it alone accounted for 37% of the variability in the EQ-5D-5L. When combining patient-reported outcome measures, the best predicting model was the one consisting of the LE CAT, Depression CAT and Pain CAT; they explained for 43.9% of the variance in EQ-5D-5L. Conclusions: The findings provide encouraging news that the LE CAT, PF CAT, Depression CAT and Pain CAT can be used alone or in combination as a proxy for the EQ-5D-5L. Researchers have the options of using these patient-reported outcome measures for economic evaluations and medical intervention studies.

Abstract: Supervision of teaching practice is an important aspect of training teachers in improving their teaching skills. Barriers such as distance and time factor are the constraints faced by the lecturers at the National University of Malaysia to communicate with the teacher trainees under their supervision. Therefore, this study aims to develop and evaluate a social-networking site Ning's platform for the supervision of lecturers to teach on-line training. This study used the case design where a total of nine teacher trainees involved in this study. It found that overall, acceptance of the use of the social-networking site Ning mean score at the highest level of 3.91. In addition, all student teachers have positive attitudes towards the use of the social-networking site Ning social-networking site and agree a suitable approach to the supervision of one of the online teaching practices. While the “blog” is the most active facility used by student teachers in which they do self-reflection. In conclusion, the social-networking site Ning has the potential to assist lecturers to carry out supervision on-line teaching practice.Ning, Social networking, supervision, teacher trainee, Islamic education
Packet Loss Concealment for G.722 using Side Information with Application to Voice over Wireless LANs
Niranjan Shetty,Jerry D. Gibson
Journal of Multimedia , 2007, DOI: 10.4304/jmm.2.3.66-76
Abstract: The G.722 wideband speech codec offers higher quality and better naturalness than G.711, is low in complexity, has low delay, and tandems well with other codecs. This makes it an attractive codec for Voice over IP and Voice over Wireless LANs. However, loss of a G.722 coded speech frame results in a mismatch of the encoder/decoder states that affects the decoding of subsequent correctly received frames. We present a new packet loss concealment (PLC) method for G.722 and propose an efficient approach to sending the side information to improve concealment of the lost frame and to resynchronize the encoder and decoder. The proposed method greatly improves the robustness of the G.722 codec to packet losses for Voice over Wireless LANs. Wideband Perceptual Evaluation of Speech Quality Mean Opinion Score (WB-PESQ MOS) is used as the quality metric for evaluating the performance of the PLC schemes.
Newer Hemostatic Agents Used in the Practice of Dermatologic Surgery
Jill Henley,Jerry D. Brewer
Dermatology Research and Practice , 2013, DOI: 10.1155/2013/279289
Abstract: Minor postoperative bleeding is the most common complication of cutaneous surgery. Because of the commonality of this complication, hemostasis is an important concept to address when considering dermatologic procedures. Patients that have a bleeding diathesis, an inherited/acquired coagulopathy, or who are on anticoagulant/antiplatelet medications pose a greater risk for bleeding complications during the postoperative period. Knowledge of these conditions preoperatively is of the utmost importance, allowing for proper preparation and prevention. Also, it is important to be aware of the various hemostatic modalities available, including electrocoagulation, which is among the most effective and widely used techniques. Prompt recognition of hematoma formation and knowledge of postoperative wound care can prevent further complications such as wound dehiscence, infection, or skin-graft necrosis, minimizing poor outcomes. 1. Introduction Dermatologists are estimated to perform over 3.9 million procedures each year [1]. Although the risks and complications of dermatologic surgery are generally very low, even the most talented surgeon can experience complications related to hemostasis during both the intraoperative and postoperative periods. Minor bleeding complications are the most frequently encountered complications of cutaneous surgery, which can predispose the patient to hematoma formation, increased risk of infection, skin graft necrosis, and wound dehiscence. This chapter will highlight proper hemostasis technique to prevent complications. 2. Overview of Hemostasis By understanding the mechanism behind the physiologic clotting system, it is easier to understand how the different hemostatic agents work in the body. The body’s primary response to injury is reflex vasoconstriction of the blood vessels in the surrounding tissues, followed by formation of the platelet plug and activation of the fibrinolytic clotting cascade. There are two separate pathways of the fibrinolytic clotting system, that lead to the final common pathway and formation of the insoluble fibrin clot. Function of the body’s hemostatic system can be monitored by various laboratory tests. These tests can be helpful to assess the degree of anticoagulation in patients on antiplatelet and anticoagulant medications or who have inherited coagulopathies before proceeding with dermatologic procedures (see Table 1). Table 1: Overview of hemostasis. 3. Preoperative Evaluation One of the most important steps that the dermatologist can take to prevent bleeding complications is to gain a thorough
University-State Child Welfare Training Partnerships: The Challenge of Matching Dollar Contributions
Jerry D. Marx,Melissa Wells
Administrative Sciences , 2013, DOI: 10.3390/admsci3040221
Abstract: Universities are uniquely positioned to provide the very best training opportunities to public child welfare workers. However, university–child welfare agency training partnerships require a significant commitment of time and resources by university personnel at a time of extensive state cuts to public higher education. This national survey of university partnership administrators found significant differences among university respondents involving length of the contractual relationship, matching dollar requirements, and overall satisfaction with the training partnership.
