The Effect of Web Characteristics on Relationship Building

The purpose of this article is to examine the relationship between Web characteristics and perceptions toward relational components. A 2 (low interactivity and high interactivity) x 2 (text-oriented and multimedia-oriented) between-group experiment was designed with 197 participants to investigate this question. The outcomes showed that interactivity has significant effects on relationship building. However, the interaction effects between interactivity and medium arrangement suggest that nonessential arrangement of interactivity and multimedia did not enhance positive perceptions of relationships with the organizations. Interactivity, however, showed that the main effect, multimedia orientation, did not. The application of interactivity on the Web was discussed for better relationship building.

Institutional image: a case study

Examines the concept of institutional (university) image from a cultural studies approach and from a quantitative perspective. Building on these and other research findings, posits that multiple changing images exist within each individual and that these images are affected by certain factors. Examines university image from an external stakeholder perspective, based on a telephone survey study of respondents from across the university’s home state. The results confirm multi‐image conceptualization of the university setting and, importantly, examine the factors – personal, environmental, and organizational – that give rise to the multiple image concept. Complementing much corporate image research that views image(s) as primarily controlled by the organization, these findings suggest that corporate image, considered also as a receiver‐oriented and audience‐specific construct, can vary as a function of other, external, determining factors but that organizational factors are, nevertheless, very influential factors for one’s decision making about image.

Searching for the Organization-Public Relationship: A Valid and Reliable Instrument

The purpose of this study is to devise a valid and reliable instrument to measure the organization-public relationship. This study has three research steps. At first, the study tests extensive items collected from the literature review using exploratory factor analysis, and then the items are tested again with confirmatory factor analysis. Lastly, the study verifies the instrument through two surveys. Through these three steps, this study finalizes a valid and reliable four-dimension scale with sixteen items for measuring the organization-public relationship. The results demonstrate that the scale is valid for other kinds of samples.

Simultaneous bilateral sequential total knee replacement is as safe as unilateral total knee replacement

We wished to determine whether simultaneous bilateral sequential total knee replacement (TKR) carried increased rates of mortality and complications compared with unilateral TKR in low- and high-risk patients. Our study included 2385 patients who had undergone bilateral sequential TKR under one anaesthetic and 719 who had unilateral TKR. There were no significant pre-operative differences between the groups in terms of age, gender, height, weight, body mass index, diagnosis, comorbidity and duration of follow-up, which was a mean of 10.2 years (5 to 14) in the bilateral and 10.4 years (5 to 14) in the unilateral group. The peri-operative mortality rate (eight patients, 0.3%) of patients who had bilateral sequential TKR was similar to that (five patients, 0.7%) of those undergoing unilateral TKR. In bilateral cases the peri-operative mortality rate (three patients, 0.4%) of patients at high risk was similar to that (five patients, 0.3%) of patients at low risk as it was also in unilateral cases (two patients, 1.0% vs three patients, 0.6%). There was no significant difference (p = 0.735) in either the overall number of major complications between bilateral and unilateral cases or between low- (p = 0.57) and high-risk (p = 0.61) patients. Also, the overall number of minor complications was not significantly different between the bilateral and unilateral group (p = 0.143). Simultaneous bilateral sequential TKR can be offered to patients at low and high risk and has an expected rate of complications similar to that of unilateral TKR.

Media or Personal Relations? Exploring Media Relations Dimensions in South Korea

This study examined the dimensions of media relations and their impact on how public relations is valued. The results showed that three factors determine media relations in South Korea. The first principal factor demonstrated existence of informal relationships in media relations. The results also affirm the personal influence model of public relations. Establishing personal relationships with journalists is a critical task among public relations practitioners. If public relations practitioners do not possess personal relationships with appropriate journalists, they often have difficulty getting media coverage. In particular, personal relationships play a critical role in the event of minimizing unfavorable media coverage.

Comparison of standard and gender-specific posterior-cruciate-retaining high-flexion total knee replacements: A PROSPECTIVE, RANDOMISED STUDY

We undertook a study in which 138 female patients with a mean age of 71.2 years (51 to 82) received a standard NexGen CR-flex prosthesis in one knee and a gender-specific NexGen CR-flex prosthesis in the other. The mean follow-up period was 3.25 years (3.1 to 3.5). The aspect ratios of the standard and gender-specific prostheses were compared with that of the distal femur. The mean post-operative Knee Society knee scores were 94 (70 to 100) and 93 (70 to 100) points and the function scores were 83 (60 to 100) and 84 (60 to 100) points for the standard implants and the gender-specific designs, respectively. The mean post-operative Western Ontario and McMaster Universities score was 26.4 points (0 to 76). Patient satisfaction, the radiological results and the complication rates were similar in the two groups. In those with a standard prosthesis, the femoral component was closely matched in 80 knees (58.0%), overhung in 14 (10.1%) and undercovered the bone in 44 (31.9%). In those with a gender-specific prosthesis, it was closely matched in 15 knees (10.9%) and undercovered the bone in 123 (89.1%). Since we found no significant differences between the two groups with regard to the clinical and radiological results, patient satisfaction or complication rate, the goal of the design of the gender-specific CR-flex prosthesis to improve the outcome was not achieved in our patients.

Comparison of total hip replacement with and without cement in patients younger than 50 years of age: THE RESULTS AT 18 YEARS

There have been comparatively few studies of the incidence of osteolysis and the survival of hybrid and cementless total hip replacements (THRs) in patients younger than 50 years of age. We prospectively reviewed 78 patients (109 hips) with a hybrid THR having a mean age of 43.4 years (21 to 50) and 79 patients (110 hips) with a cementless THR with a mean age of 46.8 years (21 to 49). The patients were evaluated clinically using the Harris hip score, the Western Ontario and McMaster Universities (WOMAC) osteoarthritis score and the University of California, Los Angeles (UCLA) activity score. Radiographs and CT scans were assessed for loosening and osteolysis. The mean follow-up was for 18.4 years (16 to 19) in both groups. The mean post-operative Harris hip scores (91 points versus 90 points), the mean WOMAC scores (11 points versus 13 points) and UCLA activity scores (6.9 points versus 7.1 points) were similar in both groups. The revision rates of the acetabular component (13% versus 16%) and the femoral component (3% versus 4%), and the survival of the acetabular component (87% versus 84%) and the femoral component (97% versus 96%) were similar in both groups. Although the long-term fixation of the acetabular metallic shell and the cemented and cementless femoral components was outstanding, wear and peri-acetabular osteolysis constitute the major challenges of THR in young patients.

Total hip replacement with a short metaphyseal-fitting anatomical cementless femoral component in patients aged 70 years or older.

We reviewed the results of 84 total hip replacements performed with a short metaphyseal-fitting anatomical cementless femoral component in 84 unselected consecutive patients with a mean age of 78.9 years (70 to 88). The mean follow-up was 4.6 years (4 to 5). The mean pre-operative Harris hip score was 26 points (0 to 56), which improved to 89 (61 to 100) at the final follow-up. No patient had thigh pain. The mean pre-operative Western Ontario and McMaster Universities osteoarthritis index score was 61 points (48 to 75), which improved to 21 (6 to 46). The mean University of California, Los Angeles activity score was 5.5 points (3 to 7) at the final follow-up. Osseointegration was seen in all femoral and acetabular components. All hips had grade 1 stress shielding of the proximal femur. No acetabular or femoral osteolysis was identified. These results demonstrate that a short metaphyseal-fitting femoral component achieves optimal fixation without diaphyseal anchorage in elderly patients.

Ethical standards appear to change with age and ideology: a survey of practitioners

Abstract The purpose of this paper is to investigate public relations practitioners’ different perceptions of professional ethics by cohort and personal ethical ideology. The results showed that both age and personal ethical ideology (idealism and relativism) had significant effects on the ethical judgment of professional ethics. Older respondents showed high idealism and low relativism, and a higher level of agreement with professional ethics. Absolutists, who are practitioners with high idealism and low relativism, showed stricter judgment of professional ethics than practitioners with other ethical ideologies. This study found that cohort and individuals’ ethical ideology can be important variables in explaining the outcomes of an individual’s ethical decision-making.

A comparison of a conventional versus a short, anatomical metaphyseal-fitting cementless femoral stem in the treatment of patients with a fracture of the femoral neck

We compared the clinical and radiological outcomes of two cementless femoral stems in the treatment of patients with a Garden III or IV fracture of the femoral neck. A total of 70 patients (70 hips) in each group were enrolled into a prospective randomised study. One group received a short anatomical cementless stem and the other received a conventional cementless stem. Their mean age was 74.9 years (50 to 94) and 76.0 years (55 to 96), respectively (p = 0.328). The mean follow-up was 4.1 years (2 to 5) and 4.8 years (2 to 6), respectively. Perfusion lung scans and high resolution chest CTs were performed to detect pulmonary microemboli. At final follow-up there were no statistically significant differences between the short anatomical and the conventional stems with regard to the mean Harris hip score (85.7 (66 to 100) versus 86.5 (55 to 100); p = 0.791), the mean Western Ontario and McMaster Universities Osteoarthritis Index (17 (6 to 34) versus 16 (5 to 35); p = 0.13) or the mean University of California, Los Angeles activity score (5 (3 to 6) versus 4 (3 to 6); p = 0.032). No patient with a short stem had thigh pain, but 11 patients (16%) with a conventional stem had thigh pain. No patients with a short stem had symptomatic pulmonary microemboli, but 11 patients with a conventional stem had pulmonary microemboli (symptomatic in three patients and asymptomatic in eight patients). One hip (1.4%) in the short stem group and eight (11.4%) in the conventional group had an intra-operative undisplaced fracture of the calcar. No component was revised for aseptic loosening in either group. One acetabular component in the short stem group and two acetabular components in the conventional stem group were revised for recurrent dislocation. Our study demonstrated that despite the poor bone quality in these elderly patients with a fracture of the femoral neck, osseo-integration was obtained in all hips in both groups. However, the incidence of thigh pain, pulmonary microemboli and peri-prosthetic fracture was significantly higher in the conventional stem group than in the short stem group.
