From social network to firm performance: The mediating effect of trust, selling capability and pricing capability

The purpose of this study is to develop a structural equation model to explain the complex relationship between social network and firm performance by introducing the mediating role of trust, selling capability and pricing capability. ,The research model with hypothesis development was derived based on the literature. To provide empirical evidence, this study carried out a survey in which the data were equated with a list of questionnaires with a random survey of 380 small and medium enterprises (SMEs) in the Indonesian context. ,This study indicates that the use of social media in management process will not affect the increasing firm performance, unless the firms build trust upon social networks. The social network with trust allows the firms to gain a pricing capability and a selling capability, which brings a positive impact on firm performance. The results also show that the selling and the pricing capabilities become essential following the utilizing the social media, which concerns on trust building. ,This study focused on the small-to-medium context, which has conventionally provided an exemplary site for the development of social capital theory but raises issues of generalizability across different contexts. ,To the managers, it is advisable to encourage their employees to consciously exploit the selling capability by enhancing the business networks via social media to achieve the firm performance. ,This paper contributes to the social capital theory by explaining the mediating role of trust in the complex relationship between social network and firm performance. This study provides evidence that trust plays a pivotal role in social networks, which enable the observed firms to achieve the performance.
The Moderating Effects of Organizational Culture on the Relationship between Work Motivation and Work Commitment of University Academic Staff

The link between the work motivation and work commitment is well established in a variety of work settings. However, the role of organizational culture is not explored in depth, especially as a moderator between work motivation and work commitment. The present study undertakes an examination of the above explained model. The sample consisted of 351 academics from nine public universities in the state of Punjab, Pakistan. Cross-sectional survey design was employed to collect the data. The statistical analyses were performed with Partial Least Squares technique using the Smart PLS 3.0. The findings revealed that adhocracy culture moderates the link between non-self-determined work motivation and work commitment among university academic staff. The study has implications for authorities to capitalize on organizational culture to boost work motivation that will ultimately improve work commitment among academics.
Optimal reconstruction of images from localized phase

The importance of localized phase in signal representation is investigated. The convergence rate of the POCS algorithm (projection onto convex sets) used for image reconstruction from spectral phase is defined and analyzed, and the characteristics of images optimally reconstructed from phase-only information are presented. It is concluded that images of geometric form are most efficiently reconstructed from their spectral phase, whereas images of symmetric form have the poorest convergence characteristics. The transition between the two extremes is shown to be continuous. The results provide a new approach and analysis of the previously reported advantages of the localized phase representation over the global approach, and suggest possible compression schemes.

Political Volunteerism : Electoral Process of Independent Candidates in Jogja Independent (JOINT)

There is a new phenomenon organized by people in Yogyakarta city-affiliated with a volunteerism movement called Jogja Independent (JOINT). It endeavored to nominate and demonstrate how independent candidates battled in Yogyakarta city's election in 2017. It was conducted by electing several candidates in public. This research was conducted to apprehend the process of independent candidate's election conducted by JOINT. By doing observation, interview and theory analysis, this paper determined some conclusions that the process of independent candidate's election conducted by JOINT had been a bandwagon and democratic. The election processes were divided into four steps: candidate nomination, appointing selectors, public fit, and proper test, and deciding the final candidate. It resulted in a couple of candidates elected democratically. Keywords—Candidate Election; Independent Candidates; Jogja Independent; Electoral
Amodiaquine and Artemether-Lumefantrine Select Distinct Alleles of the Plasmodium falciparum mdr1 Gene in Tanzanian Children Treated for Uncomplicated Malaria

ABSTRACT The artemisinin-based combination therapies artemether-lumefantrine (AL) and amodiaquine (AQ) plus artesunate have been adopted for treatment of Plasmodium falciparum malaria in many African countries. Molecular markers of parasite resistance suitable for surveillance have not been established for any of the component drugs in either of these combinations. We assessed P. falciparum mdr1 (Pfmdr1) alleles present in 300 Tanzanian children presenting with uncomplicated falciparum malaria, who were enrolled in a clinical trial of antimalarial therapy. Pfmdr1 genotype analysis was also performed with isolates from 182 children who failed AQ monotherapy and 54 children who failed AL treatment. Pfmdr1 alleles 86Y, 184Y, and 1246Y were more common among treatment failures in the AQ group than among pretreatment infections. The converse was found in the AL-treated group. Children presenting with the 86Y/184Y/1246Y Pfmdr1 haplotype and treated with AQ were significantly more likely to retain this haplotype if they were parasite positive during posttreatment follow-up than were children treated with AL (odds ratio, 33.25; 95% confidence interval, 4.17 to 1441; P, <0.001). We conclude that AL and AQ exert opposite within-host selective effects on the Pfmdr1 gene of P. falciparum.
Technological spillovers in space and firm productivity: Evidence from China’s electric apparatus industry

Using a spatial econometric model this article studies the determinants and spatial spillovers of firm productivity in China’s electric apparatus industry over the period of 1999–2007. We apply Kelejian’s FE-2SLS procedure to a higher-order spatial autoregressive model and estimate the spatial dependence of firm-level TFP within and across regional borders. The model demonstrates positive and significant intra-regional technological spillovers among firms. It also provides direct evidence that technological spillovers attenuate rapidly in spatial distance. We find that firm productivity benefits from own R&D and export activities, employment density, market competition and public expenditure. Further analyses show that the strength of spillover effects is affected by a broad range of factors, including the surface area of the region, administration type, border effect, transport and ICT infrastructure, FDI intensity, the financial sector, the utility service sector, and human capital. Factors that facilitate long-distance economic connections in general make inter-regional spillovers stronger but intra-regional spillovers weaker.
The Correlation of Indices in r-TEG with Intra-operative Blood Loss in Neurosurgical Patients.

Objective Intra-operative coagulopathy has a close relationship with blood loss and the prognosis of patients. Rapid-thrombelastography (r-TEG) is a comprehensive assessment of coagulation abnormalities and also an effective way for constructing blood transfusion. This study attempts to investigate the correlation of r-TEG indices with intra-operative hemorrhage.Methods Patients who underwent transphenoidal hypophysectomy and craniotomy from January 15 to April 30, 2013 in Peking Union Medical College hospital were recruited. All patients had pre- and post-operative r-TEG and conventional coagulation tests (CCTs). Patients' information and intra-operative blood loss as a percentage of estimated blood volume were recorded. Spearman's correlation analyses were used for discovering the relationship between indices in r-TEG or CCTs and the intra-operative blood loss. The significant correlated index of r-TEG was further investigated using linear regression analysis. Results A total of 181 patients participated in this study. Intra-operative change of α-angle, which reflects the fibrinogen level and function, was the only r-TEG index that correlated with blood loss significantly (P=0.013, r= -0.184), thus challenging the current empirical cognition of the effects of intra-operative hemorrhage on coagulation. As intra-operative blood loss increased, α-angle decreased, and every 1% loss of estimated blood volume (EBV) led to 0.60 degree decrease of α-angle. As for CCT results, changes of fibrinogen and platelet count were also significantly correlated with blood loss (P=0.015 and P=0.001, respectively). Conclusions Peri-operative change of α-angle, as an index of r-TEG, exhibited a significant negative correlation with intra-operative blood loss. The impact of hemorrhage on fibrinogen, instead of clotting factors, should be scrutinized.
Cardiac complications as initial manifestation of pheochromocytoma: frequency, outcome, and predictors.

OBJECTIVE To examine the frequency, outcome, and clinical predictors of cardiac complications as the initial manifestation of pheochromocytoma. METHODS The medical records of all 76 patients with pheochromocytoma or functional paraganglioma treated at Cedars-Sinai Medical Center, Los Angeles, California, from 1995 to 2011 were reviewed. The patients initially presenting with cardiac complications were identified, and their clinical, laboratory, and imaging characteristics were compared with those of the patients presenting with other complaints, especially hypertension and adrenal mass. RESULTS Of the 76 patients, 9 (12%) presented with the following: 2 with acute heart failure, 1 with left ventricular thrombus, 3 with myocardial infarction, and 3 with severe arrhythmia. Failure to diagnose pheochromocytoma resulted in unnecessary invasive interventions in 2 patients. Recovery of cardiac function was excellent after resection of the tumor in all patients. In comparison with the 67 patients presenting with other complaints, the 9 with cardiac complications had similar demographics and cardiac risk factors but harbored larger tumors (6.7 ± 0.8 cm versus 4.4 ± 0.3 cm; P = .015) and exhibited higher biochemical marker levels (23.9 ± 9.0-fold versus 11.3 ± 2.4-fold; P = .082), longer corrected QT interval (473 ± 8 ms versus 443 ± 6 ms; P = .015), and lower ejection fraction (43% ± 8% versus 66% ± 2%; P = .002). CONCLUSION In this study, 12% of patients with pheochromocytoma initially presented with cardiac complications. Patients with large tumors and high levels of biochemical markers were more likely to develop cardiac injury. Our results confirm that the presence of pheochromocytoma should be ruled out in patients with cardiac diseases and features suggesting pheochromocytoma so that unnecessary interventions can be avoided and cardiac recovery can be achieved.
Effects of Electronic Billboards on Driver Distraction

Objective: There is an increase in electronic advertising billboards along major roads, which may cause driver distraction due to the highly conspicuous design of the electronic billboards. Yet limited research on the impact of electronic billboards on driving performance and driver behavior is available. The Swedish Transport Administration recently approved the installation of 12 electronic billboards for a trial period along a 3-lane motorway with heavy traffic running through central Stockholm, Sweden. The aim of this study was to evaluate the effect of these electronic billboards on visual behavior and driving performance. Method: A total of 41 drivers were recruited to drive an instrumented vehicle passing 4 of the electronic billboards during day and night conditions. A driver was considered visually distracted when looking at a billboard continuously for more than 2 s or if the driver looked away from the road for a high percentage of time. Dependent variables were eye-tracking measures and driving performance measures. Results: The visual behavior data showed that drivers had a significantly longer dwell time, a greater number of fixations, and longer maximum fixation duration when driving past an electronic billboard compared to other signs on the same road stretches. No differences were found for the factors day/night, and no effect was found for the driving behavior data. Conclusion: Electronic billboards have an effect on gaze behavior by attracting more and longer glances than regular traffic signs. Whether the electronic billboards attract too much attention and constitute a traffic safety hazard cannot be answered conclusively based on the present data.
Obesity/type 2 diabetes increases inflammation, periosteal reactive bone formation, and osteolysis during Staphylococcus aureus implant‐associated bone infection

Obese and type 2 diabetic (T2D) patients have a fivefold increased rate of infection following placement of an indwelling orthopaedic device. Though implant infections are associated with inflammation, periosteal reactive bone formation, and osteolysis, the effect of obesity/T2D on these complicating factors has not been studied. To address this question, C57BL/6J mice were fed a high fat diet (60% Kcal from fat) to induce obesity/T2D, or a control diet (10% Kcal from fat) for 3 months, and challenged with a transtibial pin coated with a bioluminescent USA300 strain of S. aureus. In the resulting infected bone, obesity/T2D was associated with increased S. aureus proliferation and colony forming units. RNA sequencing of the infected tibiae on days 7 and 14 revealed an increase in 635 genes in obese/T2D mice relative to controls. Pathways associated with ossification, angiogenesis, and immunity were enriched. MicroCT and histology on days 21 and 35 demonstrated significant increased periosteal reactive bone formation in infected obese/T2D mice versus infected controls (p < 0.05). The enhanced periosteal bone formation was associated with increased osteoblastic activity and robust endochondral ossification, with persistant cartilage on day 21 that was only observed in infected obesity/T2D. Osteolysis and osteoclast numbers in obesity/T2D were also significantly increased versus infected controls (p < 0.05). Consistent with an up‐regulated immune transcriptome, macrophages were more abundant within both the periosteum and the new reactive bone of obese/T2D mice. In conclusion, we find that implant‐associated S. aureus osteomyelitis in obesity/T2D is associated with increased inflammation, reactive bone formation, and osteolysis. © 2017 Orthopaedic Research Society.

Burrow Utilization in the Goby Eutaeniichthys gilli Associated with the Mud Shrimp Upogebia yokoyai

We investigated the estuarine goby's (Eutaeniichthys gilli) utilization of mud shrimp (Upogebia yokoyai) burrows in laboratory experiments at Kochi, Japan. The goby utilized the shrimp burrow in the presence of the host, without predators, when the mud surface was covered with water. The goby spent one quarter to half the time in shrimp burrows in experimental tanks. The goby frequently entered and exited the shrimp burrows, with bout durations of several seconds to several minutes. The goby also utilized vacant artificial burrows in much the same manner. It is suggested that E. gilli feeds on small-sized crustaceans and other organic matter on the mud surface frequently utilizing shrimp burrows for possible predator avoidance even when no predator is present. Repeated evolution of burrow utilization in the North Pacific bay gobies in both the East and West Pacific would correlate with burrow commensalism in E. gilli, which is the most proximal outgroup of the bay gobies.
Firm Characteristics, Uncertainty and Research and Development (R&D) Investment: The Role of Size and Innovation Capacity

This paper examines the investment behavior of research and development (R&D) under uncertainty. We assume that there is a heterogeneous effect of uncertainty on R&D investment depending on characteristics of a firm. According to the results, the size and the innovation capacity of a firm are found to positively moderate the negative relationship between uncertainty and R&D investment. When the entire sample is divided into large and small-and-medium enterprises and high innovation capacity and low innovation capacity, it is found that the innovation capacity of a firm is a more crucial factor in positively moderating the negative relationship between R&D investment and uncertainty than the size of a firm. These findings provide policy implications, particularly for small-and-medium enterprises (SMEs), to promote R&D activities.
Consistent condom use reduces the genital human papillomavirus burden among high-risk men: the HPV infection in men study.

BACKGROUND Data supporting the efficacy of condoms against human papillomavirus (HPV) infection in males are limited. Therefore, we examined the effect of consistent condom use on genital HPV acquisition and duration of infection. METHODS A prospective analysis was conducted within the HPV Infection in Men Study, a multinational HPV cohort study. Men who were recently sexually active (n = 3323) were stratified on the basis of sexual risk behaviors and partnerships. Using Cox proportional hazards regression, type-specific incidence of HPV infection and clearance were modeled for each risk group to assess independent associations with condom use. RESULTS The risk of HPV acquisition was 2-fold lower among men with no steady sex partner who always used condoms, compared with those who never used condoms (hazard ratio, 0.54), after adjustment for country, age, race, education duration, smoking, alcohol, and number of recent sex partners. The probability of clearing an oncogenic HPV infection was 30% higher among nonmonogamous men who always used condoms with nonsteady sex partners, compared with men who never used condoms (hazard ratio, 1.29), after adjustment for country, age, race, education duration, marital status, smoking, alcohol, and number of recent sex partners. No protective effects of condom use were observed among monogamous men. CONCLUSIONS Condoms should be promoted in combination with HPV vaccination to prevent HPV infection in men.
Radiation doses to patients receiving computed tomography examinations in British Columbia.

OBJECTIVE To estimate the diagnostic reference levels and effective radiation dose to patients from routine computed tomography (CT) examinations in the province of British Columbia, Canada. METHODS The patient weight, height and computed tomography dose index or dose linear product (DLP) were recorded on study sheets for 1070 patients who were referred for clinically indicated routine CT examinations at 18 radiology departments in British Columbia. Sixteen of the scanners were multidetector row scanners. RESULTS The average patient dose varied from hospital to hospital. The largest range was found for CT of the abdomen, for which the dose varied from 3.6 to 26.5 (average 10.1) mSv. For head CT, the range was 1.7 to 4.9 (average 2.8) mSv; for chest CT, it was 3.8 to 26 (average 9.3) mSv; for pelvis CT, it was 3.5 to 15.5 (average 9.0) mSv; and for abdomen-pelvis CT, it was 7.3 to 31.5 (average 16.3) mSv. Reference dose values were calculated for each exam. These DLP values are as follows: head, 1300 mGy cm; chest, 600 mGy cm; abdomen, 920 mGy cm; pelvis, 650 mGy cm; and abdomen-pelvis, 1100 mGy cm. CONCLUSION Among hospitals, there was considerable variation in the DLP and patient radiation dose for a specific exam. Reference doses and patient doses were higher than those found in similar recent surveys carried out in the United Kingdom and the European Union. Patient doses were similar to those found in a recent survey in Germany.
In-law conflicts on television: A content analysis of "Everybody Loves Raymond"

In-Law Conflict on Television: A Content Analysis of Everybody Loves Raymond by Dawn Elise Nicol Dr. Jennifer L. Bevan, Thesis Committee Chair Assistant Professor of Communication Studies University of Nevada, Las Vegas Conflict is a relevant theme within in-law relationships and amongst family members; however, only a small amount of research deals with conflict between in-laws. In addition, television reflects social norms families can use television to understand the way they interact within interpersonal relationships. Viewing behaviors on television enable people to increase their tmderstanding of others and how they might behave in similar situations. Research should be conducted to expand our knowledge about in-law relationships and conflict on television. The purpose of this study was to examine in-law relationships and conflict on television. This study performed a quantitative content analysis of Everybody Loves Raymond (ELR) to understand trends about in-law conflict on television. The results indicated that the daughter-in-law and mother-in-law have more conflict than the daughter-in-law and father-in-law, the parents-in-law initiate conflict the most, and the daughter-in-law and mother-in-law used integrative communication whereas the fatherin-law used distributive communication.
