Mediating Identity: A Study of Media Influence on Organizational Identity Construction in a Celebrity Firm

This paper reports a longitudinal field study on the effects of positive media coverage on the reconstruction of organizational identity. The study highlights how intense positive coverage – to the point of turning an organization into a ‘celebrity’– influences both the way members understand their organization (sensemaking effect) and the gratification they derive from its positive representation (self-enhancement effect). Our findings suggest that positive media representations foster members' alignment around an emergent new understanding of what their organization is. Over time, however, celebrity may ‘captivate’ members' organizational identity beliefs and understandings, and impede further identity work as media persist in the replication of representations that differ from members' experienced reality, but are too appealing to them to be publicly contradicted.
Brain imaging in patients with freezing of gait

Freezing of gait (FOG) is a disabling gait disturbance with unknown cerebral pathophysiology. In this review, we discuss the functional brain imaging studies that address gait physiology and pathophysiology of FOG. Radiotracer metabolic studies show basal ganglia‐cortical circuitry involvement in different aspects of gait control. FOG patients showed orbitofrontal and posterior parietal deficits and possibly predominant involvement of right‐sided circuitry. We suggest that FOG results from neuronal circuitry dysfunction in right‐sided parietal‐lateral premotor circuits. These circuits incorporate sensory information into the control of gait. Furthermore, abnormal function of frontostriatal loops, which probably sheer cognitive and attentional activities is also a main factor in FOG. Gait‐induced brain circuitry activation can not adequately be achieved when investigated subjects are in a supine rest position, as is the case in most present day imaging studies. Some radiotracer activation studies were performed after walking. Imagination of gait has been used in some radiotracer activation studies with positron emission tomography (PET) and in studies with functional magnetic resonance imaging (fMRI), showing cortical activation patterns involved in several aspects of gait control. For future investigation of FOG, it is suggested to design PET and fMRI studies which concentrate on activation of neuropsychological and sensory integration circuits. © 2008 Movement Disorder Society
Examining Mechanisms Underlying Fear-Control in the Extended Parallel Process Model

ABSTRACT This investigation sought to advance the extended parallel process model in important ways by testing associations among the strengths of efficacy and threat appeals with fear as well as two outcomes of fear-control processing, psychological reactance and message minimization. Within the context of print ads admonishing against noise-induced hearing loss (NIHL) and the fictitious Trepidosis virus, partial support was found for the additive model with no support for the multiplicative model. High efficacy appeals mitigated freedom threat perceptions across both contexts. Fear was positively associated with both freedom threat perceptions within the NIHL context and favorable attitudes for both NIHL and Trepidosis virus contexts. In line with psychological reactance theory, a freedom threat was positively associated with psychological reactance. Reactance, in turn, was positively associated with message minimization. The models supported reactance preceding message minimization across both message contexts. Both the theoretical and practical implications are discussed with an emphasis on future research opportunities within the fear-appeal literature.
Correlation of Selected Affective Behaviors with Cognitive Performance in a Biology Course for Elementary Teachers.

ABSTRACT rke purpose of this study was to calculate correlation coefficient between criteria such as grades on various aspects of 'a biology course and affective behaviors. The sample consisted of 27 elementary education undergraduate students engaged in a biology course specifically designed to meet their needs. Inter-item correlation coefficients were calculated for all criteria, cognitive and noncognitive. The results indicate a high correlation between test grades and scores from a checklist of affective behaViors. Students' affective behavior scores also correlated comparatively high with achievement on laboratory and extraclass assignments. However, results indicate that a student's preference for biology did not correspond to any significant degree to his achievement in the course. (Author/BR)
Response of paramedics to terminally ill patients with cardiac arrest: an ethical dilemma.

BACKGROUND In an environment characterized by cuts to health care, hospital closures, increasing reliance on home care and an aging population, more terminally ill patients are choosing to die at home. The authors sought to determine the care received by these patients when paramedics were summoned by a 911 call and to document whether do-not-resuscitate (DNR) requests influenced the care given. METHODS The records of a large urban emergency medical services system were reviewed to identify consecutive patients with cardiac arrest over the 10-month period November 1996 to August 1997. Data were abstracted from paramedics' ambulance call reports according to a standardized template. The proportion of these patients described as having a terminal illness was determined, as was the proportion of terminally ill patients with a DNR request. The resuscitative efforts of paramedics were compared for patients with and without a DNR request. RESULTS Of the 1534 cardiac arrests, 144 (9.4%) involved patients described as having a terminal illness. The mean age of the patients was 72.2 (standard deviation 14.8) years. Paramedics encountered a DNR request in 90 (62.5%) of these cases. Current regulations governing paramedic practice were not followed in 34 (23.6%) of the cases. There was no difference in the likelihood that cardiopulmonary resuscitation (CPR) would be initiated between patients with and those without a DNR request (73% v. 83%; p = 0.17). In patients for whom CPR was initiated, paramedics were much more likely to withhold full advanced cardiac life support if there was a DNR request than if there was not (22% v. 68%; p < 0.001). INTERPRETATION Paramedics are frequently called to attend terminally ill patients with cardiac arrest. Current regulations are a source of conflict between the paramedic's duty to treat and the patient's right to limit resuscitative efforts at the time of death.
Effects of mature adipocyte-derived dedifferentiated fat (DFAT) cells on generation and vascularisation of dermis-like tissue after artificial dermis grafting

Abstract Although artificial dermis (AD) is effective for skin reconstruction, it requires two separate procedures, because the AD must be vascularised before skin grafts. To shorten the period of the dermis-like tissue generation before the secondary skin grafting must be beneficial. Dedifferentiated fat (DFAT) cells are isolated from mature adipose cell suspensions and have potential to differentiate into multiple cell types including endothelial cells. This study aimed to investigate effects of DFAT cells on dermal regeneration after AD grafts in rats. The effects of combination use of DFAT cells and basic fibroblast growth factor (bFGF) were also tested to mimic clinical situations. DFAT cells were isolated from SD rats. Full-thickness wounds were created on the back of rats followed by AD grafting. Five groups were established; Group I: control, Group II: treated with DFAT cells, Group III: treated with bFGF, Group IV: treated with both of DFAT cells and bFGF, and Group V: treated with Green fluorescent protein (GFP)-labelled DFAT cells and bFGF. Histological evaluation was serially performed. Group IV showed markedly promoted vascularisation of dermis-like tissue. In particular, capillary infiltration into the dermis was obtained within 2 days. Immunohistochemical examination revealed that the transplanted DFAT cells had differentiated into endothelial cells and participated in angiogenesis. Group IV also showed a marked increase in the thickness of the dermis like tissue. The present results suggest that the use of DFAT cells under bFGF treatment could be beneficial to shorten the period required for dermal regeneration and vascularisation and contribute to use AD more effectively and safely.
First Report of Cucumber mosaic virus Isolated from Wild Vigna angularis var. nipponensis in Korea

A viral disease causing severe mosaic, necrotic, and yellow symptoms on Vigna angularis var. nipponensis was prevalent around Suwon area in Korea. The causal virus was characterized as Cucumber mosaic virus (CMV) on the basis of biological and nucleotide sequence properties of RNAs 1, 2 and 3 and named as CMV-wVa. CMV-wVa isolate caused mosaic symptoms on indicator plants, Nicotiana tabacum cv. Xanthi-nc, Petunia hybrida, and Cucumis sativus. Strikingly, CMV-wVa induced severe mosaic and malformation on Cucurbita pepo, and Solanum lycopersicum. Moreover, it caused necrotic or mosaic symptoms on V. angularis and V. radiate of Fabaceae. Symptoms of necrotic local or pin point were observed on inoculated leaves of V. unguiculata, Vicia fava, Pisum sativum and Phaseolus vulgaris. However, CMV-wVa isolate failed to infect in Glycine max cvs. ‘Sorok’, ‘Sodam’ and ‘Somyeong’. To assess genetic variation between CMV-wVa and the other known CMV isolates, phylogenetic analysis using 16 complete nucleotide sequences of CMV RNA1, RNA2, and RNA3 including CMV-wVa was performed. CMV-wVa was more closely related to CMV isolates belonging to CMV subgroup I showing about 85.1–100% nucleotide sequences identity to those of subgroup I isolates. This is the first report of CMV as the causal virus infecting wild Vigna angularis var. nipponensis in Korea.
Bacterial Spores Survive Treatment with Commercial Sterilants and Disinfectants

ABSTRACT This study compared the activity of commercial liquid sterilants and disinfectants on Bacillus subtilis spores deposited on three types of devices made of noncorrodible, corrodible, or polymeric material. Products like Renalin, Exspor, Wavicide-01, Cidexplus, and cupric ascorbate were tested under conditions specified for liquid sterilization. These products, at the shorter times indicated for disinfection, and popular disinfectants, like Clorox, Cavicide, and Lysol were also studied. Data obtained with a sensitive and quantitative test suggest that commercial liquid sterilants and disinfectants are less effective on contaminated surfaces than generally acknowledged.
Sexual health behaviours among Pacific Island youth in Vanuatu, Tonga and the Federated States of Micronesia.

ISSUES ADDRESSED This study was conducted to describe the sexual risk behaviours of youth within the Pacific Island nations of Vanuatu, Tonga and the Federated States of Micronesia. METHODS General health behaviour surveys were conducted with youth aged 15-19 years and not attending school in the three countries. A sample of 390 Ni-Vanuatu youth from the Shefa Province, 934 youth from three island provinces of Tonga and 92 youth from Pohnpei, the main island of the four island states of the Federated States of Micronesia, were interviewed in gender-specific groups. Questions were asked about sexual behaviours that may contribute to unintended pregnancy or sexually transmitted infections (STIs). RESULTS Moderate to high percentages of youth were sexually active (had a least one sexual partner) in the Pacific island nations of Vanuatu (49.7%), Tonga (35.5%) and the Federated States of Micronesia (76.1%). Young men were more likely to engage in sexually risky behaviour than young women. They were more likely to be sexually active, have had multiple sexual partners and have had sex when drunk or high. Of those sexually active, more young men than women in Vanuatu (36.1% compared with 30.6%) and Micronesia (54.2% compared with 50%) never used protection against STIs. However, of the sexually active Tongan youth, the proportion of females (61.1%) who reported never using protection against STIs was nearly double the proportion reported by Tongan males (32.2%). CONCLUSION A high percentage of young people not attending school in the Pacific island nations of Vanuatu, Tonga and the Federated States of Micronesia are at risk of unintended pregnancy and STIs, including HIV, because of patterns of sexual risk behaviour.
An investigation into the receptivity of undergraduate students to assessment empowerment

Providing empowerment to students with regard to assessment procedures is a potential mechanism for increasing students’ satisfaction with their education programme and environment. The receptivity of students is likely to vary according to several factors, including their confidence in the ability of assessors to adequately judge the quality of their work, their understanding of assessment procedures and the degree of autonomy they feel is appropriate. Their perception of these factors can also be expected to vary according to how advanced they are in their degree programme. This paper presents the results of a pilot study into the receptivity of first‐ and third‐year undergraduate geography students to various mechanisms and concepts associated with assessment empowerment. Some receptivity to empowerment relating to choice of assessment was observed in first‐year students but the greatest receptivity was found in third‐years, at both individual and community empowerment levels. Third‐year students displayed an increased desire for assessment choice, criteria choice and community empowerment, and decreasing confidence in the lecturer as assessor. Based on these initial results, a methodology for incorporating assessment empowerment into undergraduate teaching is outlined.
A new column-generation-based algorithm for VMAT treatment plan optimization

We study the treatment plan optimization problem for volumetric modulated arc therapy (VMAT). We propose a new column-generation-based algorithm that takes into account bounds on the gantry speed and dose rate, as well as an upper bound on the rate of change of the gantry speed, in addition to MLC constraints. The algorithm iteratively adds one aperture at each control point along the treatment arc. In each iteration, a restricted problem optimizing intensities at previously selected apertures is solved, and its solution is used to formulate a pricing problem, which selects an aperture at another control point that is compatible with previously selected apertures and leads to the largest rate of improvement in the objective function value of the restricted problem. Once a complete set of apertures is obtained, their intensities are optimized and the gantry speeds and dose rates are adjusted to minimize treatment time while satisfying all machine restrictions. Comparisons of treatment plans obtained by our algorithm to idealized IMRT plans of 177 beams on five clinical prostate cancer cases demonstrate high quality with respect to clinical dose–volume criteria. For all cases, our algorithm yields treatment plans that can be delivered in around 2 min. Implementation on a graphic processing unit enables us to finish the optimization of a VMAT plan in 25–55 s.
Refining and Developing Features Describing Dementia-related Changes in Structural and Functional Imaging

This dissertation aims at advancing computer-aided diagnosis of neurodegenerative diseases, in particular when differentiating various stages of dementia. The focus is on developing and refining disease-related features based on structural and functional imaging. The first part of the thesis addresses the refinement of such features based on crosssectional functional imaging data. Intensity values or volume measurements are extracted from each volume and a classification of various dementia types is premised on variance-based statistical analysis. Prior to this, several necessary preprocessing steps are evaluated in order to compare different subjects. When applying the methods developed in the first part of the thesis to structural imaging data it is observable that preprocessing of these high-resolution images is not only time-consuming and prone to error but also that its quality cannot be assessed without the help of clinical experts. The second part of this thesis therefore discusses features which are independent from preprocessing quality in longitudinal data. These newly developed features are based on tracing punctual changes within the brain. Interesting points are furthermore examined in order to detect if they show significantly different behavior over a period of two years for various stages of Alzheimer’s dementia. A classification based on significant features is employed to differentiate dementia in various stages.

DNA Methylation Status of Key Cell-Cycle Regulators Such as CDKNA2/p16 and CCNA1 Correlates with Treatment Response to Doxorubicin and 5-Fluorouracil in Locally Advanced Breast Tumors

Purpose: To explore alterations in gene promoter methylation as a potential cause of acquired drug resistance to doxorubicin or combined treatment with 5-fluorouracil and mitomycin C in human breast cancers. Experimental Design: Paired tumor samples from locally advanced breast cancer patients treated with doxorubicin and 5-fluorouracil-mitomycin C were used in the genome-wide DNA methylation analysis as discovery cohort. An enlarged cohort from the same two prospective studies as those in the discovery cohort was used as a validation set in pyrosequencing analysis. Results: A total of 469 genes were differentially methylated after treatment with doxorubicin and revealed a significant association with canonical pathways enriched for immune cell response and cell-cycle regulating genes including CDKN2A, CCND2, CCNA1, which were also associated to treatment response. Treatment with FUMI resulted in 343 differentially methylated genes representing canonical pathways such as retinoate biosynthesis, gαi signaling, and LXR/RXR activation. Despite the clearly different genes and pathways involved in the metabolism and therapeutic effect of both drugs, 46 genes were differentially methylated before and after treatment with both doxorubicin and FUMI. DNA methylation profiles in genes such as BRCA1, FOXC1, and IGFBP3, and most notably repetitive elements like ALU and LINE1, were associated with TP53 mutations status. Conclusion: We identified and validated key cell-cycle regulators differentially methylated before and after neoadjuvant chemotherapy such as CDKN2A and CCNA1 and reported that methylation patterns of these genes may be potential predictive markers to anthracycline/mitomycine sensitivity.

Comparing the Quality of Life of Patients Requesting Dental Implants Before and After Implant

Background and Objectives: Tooth loss is a serious life event that impairs two important functions, namely, eating and speaking, and has significant side effects on different aspects of quality of life. These effects are internalized by the individual. The present study aimed to compare the quality of life (QOL) of patients requesting dental implants before and after implant. Materials and Methods: This analytical cross-sectional study was conducted on patients referred to the Mashhad faculty of Dentistry and private clinics with dental implants in 2015. Patient Quality Of Life (QOL) was assessed using the Oral Impact on Daily Practice (OIDP) questionnaire. Data were analyzed using SPSS software. Results: In this study, the most common problems reported by patients were eating (78%), smiling, laughing, and embarrassment (53%) before surgery. The quality of life associated with eating; speaking clearly; clean teeth or dentures; light physical activities, such as working at home, going out to work or meeting others; smiling; laughing; showing teeth without discomfort and embarrassment; emotional conditions, such as becoming upset quicker than usual, enjoying communication with others (i.e., friends, relatives and neighbors); and job-related activities significantly increased after surgery, but QOL associated with the amount of sleep and resting did not improve. No significant association was noted between quality of life after implantation and place of residence, education and gender. Conclusion: In this study, implants had a favorable impact on a patient’s quality of life.
The Search for Oculomotor Inhibition

When a saccadic target is presented simultaneously with a distractor, the distractor has to be inhibited in order to successfully perform an eye movement to the target. Insufficient inhibition results in an erroneous eye movement to the distractor. This study investigated whether the influence of a distractor on eye movements is mediated by working memory. A working memory task was added to a saccadic paradigm in which an irrelevant element had to be inhibited. Results show that participants made more erroneous saccades to the distractor when working memory was occupied. This suggests that working memory is involved in the oculomotor inhibition of saccadic distractors.
Effects of Provided Trainings Regarding Non-Invasive Mechanical Ventilation on the Knowledge Level of Nurses

INTRODUCTION Noninvasive mechanical ventilation (NIMV) is the administration of respiratory support via the upper respiratory tract without using an invasive artificial airway (1, 2). It is indicated in the literature that NIMV should be performed during the treatment of diseases that cause hypercapnic respiratory failure and of chronic obstructive pulmonary diseases accompanied by respiratory acidosis (3-5).
Selling ‘securityware’

In this article, I examine how the marketing of penal commodities and the use of ‘security’ as a selling point has developed and proliferated over the past 50 years in the US corrections market. Using data obtained from a contextual analysis of display advertisements from the correctional trade periodical, Corrections Today and its predecessors, I trace the transformation of the major message modes of the sales pitches, from how the promoted products and/or services can benefit inmate moral and rehabilitative efforts to how they can enhance institutional security. I conclude by discussing the current state of marketing security in the penal realm, and how it appears to shape the nature and quality of institutional life, as well as its theoretical implications in terms of what this aspect of the penal enterprise might tell us about of the state of contemporary punishment.
