Brand community integration and satisfaction with social media sites: a comparative study

Purpose This paper aims to address two primary research questions: Why does a consumer integrate into a brand community and how does that impact overall satisfaction with the brand? Which of the main social media sites (Facebook, Twitter, LinkedIn and Pinterest) is more/less appropriate for cultivating a brand community? Design/methodology/approach Data were collected via an online survey of college students at two universities. The data were analyzed using structural equation modeling with AMOS software. Findings Results suggest that brand community does lead to satisfaction with a social media brand. Consumers are more likely to integrate into a brand community if they view the site as personally relevant. Relevancy is affected by the frequency with which the consumer visits the site. The analysis also indicates that there are interesting differences among the different sites. Research limitations/implications This study has some limitations due to the demographics of the respondents and the finite listing of sites. Practical implications Social media marketers looking to build brand community and increase satisfaction will be able to use the results of this study to make informed decisions regarding these efforts. Social implications Society could benefit from this study if marketers use the findings to engage consumers in brand communities through social media. Brand communities help participants to feel more engaged and connected to others. It is well known that people thrive in community settings and this togetherness, as opposed to isolation, will be good for the participants and society in general. Originality/value The understanding of why a consumer would integrate into a brand community is valuable information because it is generally known and accepted that there are positive results for the brand, but this study takes it a step further and looks at the specific social media sites to give guidance to marketing practitioners as to which ones are best for brand community building.
Intervening role of realized absorptive capacity in organizational culture–open innovation relationship

Using data collected from middle and top managers working across different industries in the United Arab Emirates, this article examines the relationship between two contrasting organizational culture types and two types of open innovation (OI). It also takes into account the mediating role of realized absorptive capacity in these relationships. Results obtained using several statistical techniques show that a highly integrative culture relates positively, while a hierarchy culture relates negatively to the two types of OI. Results also establish the mediating role of realized absorptive capacity in these relationships. These findings contribute theoretically to OI and organizational culture literature and provide insights for practitioners on how to succeed or avoid failure in their OI initiatives. A discussion of the findings, along with limitations of the study and future research directions, is given.
Squamous cell carcinoma of the lip: depth of invasion, local recurrence and regional metastases. Experience of a rural multidisciplinary head and neck unit

Abstract Background: The internationally recognised American Joint Committee on Cancer (tumour–node–metastasis) staging system utilises tumour size to determine stage. Other factors (i.e. tumour depth) may provide additional prognostic information. Method: A thorough retrospective analysis was performed of 68 patients with primary lip squamous cell carcinoma operated on or discussed by the Darling Downs Health Service between 2005 and 2013. Results: Twelve patients developed lymphatic spread. There was a statistically significant increased risk of nodal metastasis in: patients with tumours of increased thickness (U = 103.50; degrees of freedom = 68; p < 0.001), those with a larger overall tumour size (U = 163.50; degrees of freedom = 68; p = 0.005) and patients living further from the treatment centre (U = 199.00; degrees of freedom = 68; p = 0.018). Conclusion: It may be reasonable that other factors are considered for staging of lip squamous cell carcinomas, in combination with tumour–node–metastasis staging. Depth of invasion may have utility in prognosis and treatment; however, larger prospective analysis needs to be performed. Patients living in a more rural setting presented with more advanced disease, suggesting an ongoing rural–metropolitan gap in healthcare.
Significant dissociation of expression patterns of the basic helix–loop–helix transcription factors Dec1 and Dec2 in rat kidney

SUMMARY Dec1 and Dec2 are regulators of the mammalian molecular clock that show robust circadian rhythms in the suprachiasmatic nucleus and various peripheral tissues. Although the expression of Dec1 and Dec2 is altered by multiple stimuli in different organs, their transcriptional regulatory mechanisms have not been fully elucidated for the kidney. In the present study, we describe for the first time significant dissociation of expression patterns with arrhythmic expression of Dec1 and rhythmic expression of Dec2 in rat kidney under a normal light–dark (LD) cycle. Daytime restricted feeding (RF) significantly altered the expression patterns of these two clock genes, and even induced circadian expression of Dec1 with an amplitude of 2.2 on day 3 and 4.2 on day 7. However, when a reversed feeding schedule was coupled with a reversed LD cycle, the expression of Dec1 but not Dec2 reverted to being arrhythmic. Moreover, exogenous injection of the glucocorticoid analogue dexamethasone (Dex) at certain times of the day resulted in rhythmic expression of Dec1, which was similar to that seen following RF for 7 days. In contrast, endogenous disruption of glucocorticoids by adrenalectomy abolished RF-induced rhythmic expression of Dec1 in the kidney. These observations suggest the existence of a glucocorticoid gating mechanism in the circadian expression of Dec1 in rat kidney.
Primary Repair of Retinal Detachment With 25-Gauge Pars Plana Vitrectomy

Purpose: To evaluate 25-gauge pars plana vitrectomy (PPV) for primary repair of rhegmatogenous retinal detachment (RRD). Study Design and Participants: This retrospective, consecutive case series included 42 eyes of 41 patients who underwent primary repair of RRD utilizing transconjunctival 25-gauge PPV without scleral buckling at the Cincinnati Eye Institute from July 2004 through January 2007. Methods: The medical records were retrospectively reviewed, and the corresponding demographic data, preoperative ophthalmic diagnoses, surgical management, and postoperative course and treatment were recorded. Main outcome measures included single surgery anatomical success, preoperative and postoperative visual acuity, and complications. Results: Most patients had pseudophakic RRD (36 [85.7%] of 42 eyes). The crystalline lens was present in the remaining 6 eyes (14.3%). Of 42 eyes, 28 (66.7%) had macula-on RRD, while 14 (33.3%) had macula-off RRD. Four surgeons contributed to this study, and 25-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and gas tamponade were used in each case. The single surgery anatomical success rate was 92.9% (39 of 42 eyes). For eyes with macula-on RRD, best-corrected visual acuity was 20/50 (0.43 logMAR [logarithm of the minimum angle of resolution]) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.24). For eyes with macula-off RRD, best-corrected visual acuity was 5/200 (1.56 logMAR) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.001). Three eyes required additional surgery for final reattachment. Final reattachment was achieved in 100% of patients (mean follow-up, 8 months). Conclusions: Twenty-five–gauge PPV with laser retinopexy and gas tamponade is effective for primary repair of RRD. The single operation anatomical success rate is comparable with rates reported for primary vitrectomy with 20-gauge instrumentation, scleral buckling, and combined vitrectomy/scleral buckling.
Effects of long-term liquid commercial semen extender and storage time on the membrane quality of boar semen

The objective of this study was to assess the sperm membrane integrity in extended boar semen during storage time using specific spectrum laboratory methods. Boar semen was diluted with the long-term liquid commercial extenders Androhep (A), Androstar (AS), Androstar plus (AS + ), LD and M III and was stored up to 96 h. The sperm membrane integrity was evaluated by motility, viable spermatozoa, short hypoosmotic swelling test (sHOST) and by the activity of the enzyme aspartate aminotransferase (AST). Negative changes in the quality of sperm membrane in relation to storage time were observed after 48 h for sHOST, after 72 h for viable spermatozoa and after 72 h for motility. The percentage of viable spermatozoa was decreased by 0.27% each hour. A statistically significant difference between extenders A and LD was observed in sHOST after 72 h and 96 h storage ( P < 0.05). The AST activity did not show any statistically significant differences in extenders and in storage time. In overall assessment Androhep was the best of the tested extenders, followed by AS, AS + , M III and LD in terms of motility, viable spermatozoa and sHOST. The correlations among laboratory methods were highly significant ( P < 0.001). In conclusion, the results documented that the sperm membrane integrity was statistically significantly affected by extenders and storage time ( P < 0.001). Boar semen quality was the best in extender A. sHOST is a very sensitive and relatively simple method for the assessment of sperm membrane integrity in diluted semen.
Steering in a Random Forest

Objective: The aim of this study was to design and evaluate an algorithm for detecting drowsiness-related lane departures by applying a random forest classifier to steering wheel angle data. Background: Although algorithms exist to detect and mitigate driver drowsiness, the high rate of false alarms and missed detection of drowsiness represent persistent challenges. Current algorithms use a variety of data sources, definitions of drowsiness, and machine learning approaches to detect drowsiness. Method: We develop a new approach for detecting drowsiness-related lane departures using steering wheel angle data that employ an ensemble definition of drowsiness and a random forest algorithm. Data collected from 72 participants driving the National Advanced Driving Simulator are used to train and evaluate the model. The model’s performance was assessed relative to a commonly used algorithm, percentage eye closure (PERCLOS). Results: The random forest steering algorithm had a higher classification accuracy and area under the receiver operating characteristic curve than PERCLOS and had comparable positive predictive value. The algorithm succeeds at identifying two key scenarios associated with the drowsiness detection task. These two scenarios consist of instances when drivers depart their lane because they fail to modulate their steering behavior according to the demands of the simulated road and instances when drivers correctly modulate their steering behavior according to the demands of the road. Conclusion: The random forest steering algorithm is a promising approach to detect driver drowsiness. The algorithm’s ties to consequences of drowsy driving suggest that it can be easily paired with mitigation systems.
Racial disparities in the outcomes of communication on medical care received near death.

BACKGROUND Black patients tend to receive more life-prolonging care at the end of life (EOL) than white patients. This study aimed to evaluate whether differences in patient-physician communication contribute to disparities in EOL care between black patients and white patients. METHODS Multi-institutional prospective longitudinal cohort study of 71 black patients and 261 white patients with advanced cancer. The main outcome measures were differences between black patients and white patients in relationships among EOL discussions and communication goals (terminal illness awareness, treatment preferences, and do-not-resuscitate [DNR] orders) and EOL care outcomes (life-prolonging care, hospice care, and receipt of EOL care consistent with preferences). RESULTS End-of-life discussions between physicians and their white patients were associated with less life-prolonging EOL care compared with their black patients (adjusted odds ratio [aOR], 0.11; P = .04). Despite similar rates of EOL discussions (black vs white patients 35.3% vs 38.4%, P = .65), more black patients than white patients received life-prolonging EOL care (19.7% vs 6.9%, P = .001). End-of-life discussions were associated with attainment of some communication goals among black patients, including placement of DNR orders (aOR, 4.25; P = .04), but these communication goals were not consistently associated with EOL care received by black patients. For example, black patients with DNR orders were no less likely than black patients without DNR orders to receive life-prolonging EOL care (aOR, 1.57; P = .58). CONCLUSIONS End-of-life discussions and communication goals seem to assist white patients in receiving less life-prolonging EOL care, but black patients do not experience the same benefits of EOL discussions. Instead, black patients tend to receive life-prolonging measures at the EOL even when they have DNR orders or state a preference for symptom-directed care.
THE STRATEGIC ROLES OF HUMAN RESOURCE MANAGER TO ACHIEVE COMPETITIVE ADVANTAGE IN HOSPITALITY INDUSTRY

The global challenges in the economic sector has become more complex and turbulence. Many companies have executed management changes in order to survive and create strategies to compete with their competitors. More than two decades, human resource management has been developed into strategic to face the global challenges, and the roles concept of human resource professional created by Ulrich et. al. has been executed by many companies around the world. Many researchers have stated that a key to achieving competitive advantage is that of the strategic roles of human resource management. In the service industry, specifically in hospitality, in which human resource as the main resource to run the business, the strategic roles of the human resource manager is very important in creating competitive advantage. This research aims to identify and describe the strategic roles of human resource managers in a hospitality industry. This study conducted in three-star hotels in Malang and interviewed six human resource managers as participants. Qualitative method used in this research and positivist underlying philosophical assumption. Using semi-structured interview in data collection, this paper identifies three themes to be analyzed by coding using software NVivo International 10. The first is the strategic roles of human resource managers contribute to anticipating the competitive business challenges; the second, their strategic roles in creating competitive advantage; and lastly, a human resource as a key in creating the competitive advantage for the company. The first two themes are analyzed by a number of coding references, the finding mentioned that there are two human resource managers who conduct strategic roles as the strategic partner and change agent. While the third theme is analyzed by word tree and giving the result that the factor of achieving competitive advantage is that of human resource.
Factors affecting Millennials Employee Engagement in Government Sector

These day employee engagement plays a fundamental role in government sector. It is significant for the government to realize that it isn't completely depends on the employees to implement the engagement. This study was directed because of the rising issue of employee engagement among Millennials that have different importance and opinion towards their job. A study was done on a sample of 80 government employees. All three hypotheses were accepted in this study. Results showed that there is a significance relationship between independent and dependent variables. The finding suggests the Pakistani government to adopt better engagement system to retain the employees and improve organizational performance.
Distracted Investors and Earnings Management

In this study, we examine whether investor distraction affects earnings management. We use a firm-level measure of investor distraction that captures times when institutional investors shift their attention to unrelated parts of their portfolios. Distracted investors temporarily loosen their monitoring intensity and managers may take advantage of it. Our main finding is that, when shareholders are distracted, managers engage in income-increasing earnings management. Due to the exogenous nature of the measure of investor distraction, we argue that this association is causal. The effect of investor distraction on earning management is concentrated in firms where managers have greater incentives to manipulate earnings. Our results are robust to falsification tests and to the use of an alternative measure of investor attention based on news reading and news searching activities on Bloomberg terminals.
Comparative micro‐Raman study of the Nakhla and Vaca Muerta meteorites

A comprehensive micro-Raman spectroscopic analysis of the Nakhla and Vaca Muerta meteorites is reported. The major and minor mineral components were identified from comparison with mineralogical standards and literature databases. The compositions of pyroxenes and olivines were obtained using only this technique and correlation data between band parameters and the chemical composition of reference materials existing in the literature. The presence of calcite in both meteorite specimens was noted; its identification inside eucrite grains in the Vaca Muerta meteorite is particularly noteworthy. Their spectral parameters show strong similarities. Aragonite associated with calcite is reported for the first time in Vaca Muerta meteorite. Spectra of siderite, which appears associated with clinopyroxenes, are also reported in Nakhla meteorite. Iron oxides were analysed in detail in both meteorites. Magnetite is the main oxide phase observed in Nakhla and goethite, lepidocrocite and magnetite in Vaca Muerta. In both cases haematite was not observed. A comparison of the spectral parameters of these mineral phases observed in both meteorites was made and their possible origin as secondary minerals is discussed. This study stresses the potential of Raman spectroscopy in the mineralogical characterization of meteorites on a very small scale and also the potential applications of Raman spectroscopy for use on landers or rovers on the surface of Mars or other planetary bodies.

Payments for environmental services and community-level socioeconomic wellbeing: Comparing programs in Vietnam and Australia

The success of Payments for Environmental Services (PES) programs depend crucially on local conditions, although some considerations can help make PES schemes more successful in any locale. Many PES programs are in their infancy yet have ambitious goals for environmental preservation and poverty alleviation. Monitoring and evaluating the outcomes of PES programs can provide insights into how they can best achieve these goals. This research adds to existing PES case studies by evaluating new data on one village’s participation in a World Wildlife Fund PES scheme. A village in central Vietnam was visited and the Administrative Chief of the village was interviewed to gauge the success of the PES scheme in that village. The comments from the Vietnamese village were then compared to written and verbal accounts of the Working on Country program in Australia to elucidate factors that can make PES schemes successful. This comparison revealed four key factors that can improve the outcomes of PES schemes. Community involvement in the design, implementation and evaluation of projects is crucial. Furthermore, the monetary remuneration that the community receives should be adequate. In addition, PES schemes are particularly successful when the community receives non-monetary benefits, such as social or cultural benefits, from participating in the program. Finally, the involvement of outside organisations, including the state, needs to be adequate and appropriate to ensure positive socioeconomic outcomes for the communities involved.
Effect of mycophenolic acid and bortezomib on purified human B cells: an in vitro study of long-term functionally stable MICA-sensitized renal recipients.

OBJECTIVES We sought to develop a B-cell in vitro culture system and test B cells isolated from sensitized kidney recipients and healthy controls, and assess the effectiveness of proteasome inhibitors and mycophenolic acid on antibody secretion and cell apoptosis. MATERIALS AND METHODS CD19(+) B cells and CD19(+)CD27(+) memory B-cell subsets were detected from peripheral blood mononuclear cells obtained from 6 MICA-sensitized kidney recipients and 6 healthy controls. Peripheral blood B cells were isolated and cultured with CpG2006, PMA, MICA antigen, B-cell activating factor, CD40 ligand (CD40L), human recombinant IL-2 (rhuIL-2), rhuIL-10, rhuIL-4, and rhuIL-21. After culturing for 7 days, we tested several variables of B-cell activity including differentiation, apoptosis, and IgM production. We also assessed the effects of 2 immunosuppressive drugs (mycophenolic acid and bortezomib) on antibody secretion and cellular apoptosis. RESULTS Kidney recipients had a lower ratio of CD19+ B cells in peripheral blood mononuclear cells than did healthy controls. However, the percentage of CD19(+)CD27(+) B cells was higher in kidney recipients than in healthy controls. In the cell stimulation culture system, the ratio of CD19(+) B cells, CD19(+)CD27(+) B cells, and CD19(+)CD138(+) B cells increased after culturing for 7 days compared with unstimulated controls. In addition, the percentage of apoptotic B cells decreased, and antibody production increased in sensitized transplant patients and healthy controls. Treatment with bortezomib or mycophenolic acid induced B-cell apoptosis and inhibited secretion of antibodies. CONCLUSIONS This study describes establishment of a B-cell in vitro culture system, showing that B cells may be stimulated to secrete antibodies. The study also provides an assay for studying B cells in vitro. This study provides information suggesting that bortezomib and mycophenolic acid can inhibit B-cell antibody secretion.
The Impact of Analytics Utilization on Team Performance: Comparisons Within and Across the U.S. Professional Sports Leagues

Business analytics, defined as the use of data to make better, more relevant, evidence-based business decisions, has received a great deal of attention in practitioner circles. Organizations have adopted business analytics in an effort to improve revenue, product placement, and customer satisfaction. Professional sports teams are no different. While analytics has been used for over 30 years, the use of analytics by professional sports teams is a relatively new concept. However, it is unclear whether the teams that have adopted analytics are seeing any results. If not, then perhaps analytics is not the right solution. Analyses across the four, major U.S. sports leagues and within leagues show little to no competitive (on-field) or attendance (off-field) differences for the teams that have adopted analytics. Areas for additional research are provided in order to better understand the apparent disconnect between the hype in the sports industry and the lack of measurable results.
