Extant public administration network literature tend to conceptualize and measure relationships in networks based on the premise that the nodes and ties in networks lie on a single-level horizontal structure. The purpose of the current study is to suggest that networks are inevitably multi-level and multi-dimension structures and propose a multi-level multi-dimension network model (MLMD). More specifically, network relationships such as within-level, inter-level, and inter-sector are offered to depict the multi-layered and multi-sectoral nature of the network relationships among the government and non-government actors. For empirical analysis, the current study constructs a hypothetical network to describe MLMD. © 2017, Springer Science+Business Media New York.

Rationale & Objective:We aimed to study the comparative effectiveness of percutaneous coronary intervention with drug-eluting stent and coronary artery bypass grafting in patients receiving dialysis. Study Design:This was a retrospective observational cohort study. Setting & Participants:This population-based study identified patients receiving dialysis hospitalized for coronary revascularization between January 1, 2009 and December 31, 2015, in the Taiwan National Health Insurance Research Database. Exposures:Patients received percutaneous coronary intervention with drug-eluting stent versus coronary artery bypass grafting. Outcomes:The study outcomes were all-cause mortality, in-hospital mortality, and repeat revascularization. Analytical Approach:Propensity scores were used to match patients. Cox proportional hazards models and logistic regression models were constructed to examine associations between revascularization strategies and mortality. Interval Cox models were fitted to estimate time-varying hazards during different periods. Results:A total of 1,840 propensity score-matched patients receiving dialysis were analyzed. Coronary artery bypass grafting was associated with higher in-hospital mortality (coronary artery bypass grafting vs percutaneous coronary intervention with drug-eluting stent; crude mortality rate 12.5% vs 3.3%; adjusted OR, 5.22; 95% CI, 3.42-7.97; < 0.001) and longer hospitalization duration (median [IQR], 20 [14-30] days vs 3 [2-8] days; < 0.001). After discharge, repeat revascularization, acute coronary syndrome, and repeat hospitalization all occurred more frequently in the percutaneous coronary intervention with drug-eluting stent group. Importantly, with a median follow-up of 2.8 years, coronary artery bypass grafting was significantly associated with a higher risk of all-cause overall mortality (adjusted HR, 1.19; 95% CI, 1.05-1.35; = 0.006) in the multivariable Cox proportional hazard model.

Background/Purpose: This study aims to establish reference intervals for important biochemical parameters in cord blood of newborn male and female infants in Taiwan and to investigate their sex difference. We also examined the correlation of the same markers between maternal blood levels and neonatal cord blood levels. Methods: 2,136 pregnant women receiving regular routine prenatal health assessments in their third trimester (weeks 29–40) were recruited from nine hospitals in Taiwan between 2012 and 2015. After exclusion, we were left with 580 cord blood samples to include in this study. Results: Cord blood thyroid-stimulating hormone was higher in males than females (p < 0.05). Males also had significantly higher sex hormone levels (estradiol, follicle-stimulating hormone, and sex hormone-binding globulin), while females had higher levels of luteinizing hormone. Male newborns had higher cord blood immunoglobulin E (IgE), while females had higher insulin-like growth factor-1 (IGF-1) levels. We found a slight positive link between maternal blood and cord blood in thyroid hormones and sex hormones. Conclusion: This study found sex differences in cord blood thyroid hormone, sex hormone, IGF-1, and IgE levels and a link between maternal blood levels of thyroid and sex hormones and those in the cord blood of their infants. © 2023 Elsevier B.V.

Information security has gained increasing attention in the past decade, leading to the development of advanced materials for anti-counterfeiting, encryption and instantaneous information display. However, it remains challenging to achieve high information security with simple encryption procedures and low-energy stimuli. Herein, a series of strain/temperature-responsive liquid crystal elastomers (LCEs) are developed to achieve dual-modal, multi-level information encryption and real-time, rewritable transient information display. The as-prepared polydomain LCEs can change from an opaque state to a transparent state under strain or temperature stimuli, with the transition strains or temperatures highly dependent on the concentration of long-chain flexible spacers. Information encrypted by different LCE inks can be decrypted under specific strains or temperatures, leading to multi-level protection of information security. Furthermore, with the combination of the phase transition of polydomain LCEs and the photothermal effect of multi-walled carbon nanotubes (MWCNTs), we achieved a repeatable transient information display by using near-infrared (NIR) light as a pen for writing. This study provides new insight into the development of advanced encryption materials with versatility and high security for broad applications.

The development of chiral optical active materials with switchable circularly polarized luminescence (CPL) signals remains a challenge. Here an azoarene-based circularly polarized luminescence molecular switch, ( S, R, S )-switch 1 and ( R, R, R )-switch 2 , are designed and prepared with an ( R )-binaphthyl azo group as a chiral photosensitive moiety and two ( S )- or ( R )-binaphthyl fluorescent molecules with opposite or the same handedness as chiral fluorescent moieties. Both switches exhibit reversible trans/cis isomerization when irradiated by 365 nm UV light and 520 nm green light in solvent and liquid crystal (LC) media. In contrast with the control ( R, R, R )-switch 2 , when switch 1 is doped into nematic LCs, polarization inversion and switching-off of the CPL signals are achieved in the resultant helical superstructure upon irradiation with 365 nm UV and 520 nm green light, respectively. Meanwhile, the fluorescence intensity of the system is basically unchanged during this switching process. In particular, these variations of the CPL signals could be recovered after heating, realizing the true sense of CPL reversible switching. Taking advantage of the unique CPL switching, the proof-of-concept for “a dual-optical information encryption system” based on the above CPL active material is demonstrated.

OBJECTIVE:To evaluate the association between human papillomavirus (HPV) infection and the subsequent risk of developing glaucoma using real-world data. DESIGN:Retrospective cohort study. SUBJECTS AND CONTROLS:Adults aged ≥18 years with a diagnosis of HPV were identified from the TriNetX research network and matched 1:1 to individuals without HPV based on demographics, comorbidities, and healthcare utilization patterns. METHODS:Propensity score matching was performed to balance baseline characteristics. Cox proportional hazards models were used to estimate the hazard ratios (HRs) for incident glaucoma. Sensitivity analyses and subgroup stratifications were conducted to assess robustness. MAIN OUTCOME MEASURES:Incident diagnosis of glaucoma, including open-angle and angle-closure subtypes, following HPV infection. RESULTS:Among 451,288 matched participants, HPV infection was associated with an increased risk of glaucoma (HR: 1.34; 95% CI: 1.28-1.41), with elevated risks observed for both open-angle (HR: 1.33; 95% CI: 1.16-1.52) and angle-closure glaucoma (HR: 1.66; 95% CI: 1.20-2.30). The association was more pronounced in older adults, males, and Asians, and further amplified by comorbidities such as hypertension, diabetes, and myopia. Results were consistent across sensitivity analyses. CONCLUSION:HPV infection is associated with a higher risk of glaucoma. While these findings highlight a potential need for increased ophthalmologic surveillance in HPV-positive individuals, the possibility of surveillance bias, in which individuals with HPV may receive more frequent healthcare and eye examinations, cannot be excluded. Further studies are warranted to explore causal mechanisms and control for potential confounding.

The Role of Firm's Unique Resource in Developing Sustainable Competitive Advantage from Strategy Inimitability and its Effect on Firm Performance of Mining Companies in Indonesia

引用

Journal of Physics: Conference Series 2019年第9期1341卷

作者： Abdul Rauf Abd. Rahman Kadir Najmi Kamariah Ph.D Post Graduate School of Economics Hasanuddin University South Sulawesi Indonesia Professor of Economics Post Graduate School of Economics Hasanuddin University South Sulawesi Indonesia School of State Administration Business administration Program Makassar South Sulawesi Indonesia

The positive relationship between unique resources and sustainable competitiveness of the company has been well understood and applies to almost all businesses. However, little is known about the specific effects of the uniqueness of resources and business strategies in this relationship. Using resource-based view (RBV), Porter's five-factor theory, and game theory, as well as imitation theory between companies, this study explains how the influence of company-specific resources and the uniqueness of the company's strategy as a sustainable competitive advantage affect performance. Analysis of data collected from surveys on 101 mining companies in Indonesia shows companies with distinctive resources are able to produce unique business strategies and insofar as they cannot be replicated, companies can enjoy sustainable competitive advantage. This implies that mining companies need to avoid their resources and business strategies to be imitated by their competitors if the company still wants to maintain competitive advantage and performance.
