DEVELOPING SUPPLY CHAIN DYNAMIC CAPABILITY TO REALIZE THE VALUE OF INTER-ORGANIZATIONAL SYSTEMS

In face of increasingly complex supply chain, firms are taking steps to develop different kinds of inter-organizational systems (IOS) to facilitate information sharing and sustain competitive competency. These systems are expected to provide great business value, however many of them do not fulfill the expected promise as these systems are relatively more complicated and the usage is across supply chains. Built upon process theory and the view of dynamic capability, this study has defined two supply chain dynamic capabilities (SDC) -- supply chain integration capability and supply chain cooperation capability and proposed that they might significantly moderate IOS performance. A general survey is conducted in Taiwan PC industry to validate the research model. A linear regression is used to testify the hypotheses. The results show that improving SDC can create greater IOS performance. Furthermore, supply chain integration capability has stronger moderating effect of IOS performance than supply chain cooperation capability. These findings contribute to the literature by confirming the influence of SDC on IOS performance and also by showing which SDC is of primary importance to firms

CUSTOMER READINESS, MARKET ORIENTATION AND TRANSACTION FREQUENCY IN MOBILE BANKING SERVICE RECOVERY

This study investigates the effect of internet banking service recovery satisfaction on future intention toward using mobile banking, and examines transaction frequency as a moderator of this relationship. Moreover, this study applies customer participation in service recovery and service recovery experience as the influential factors of service recovery satisfaction. Questionnaires were obtained 419 respondents with internet banking and service recovery experience. The results of SEM analysis illustrate that both role clarity and ability of service recovery can affect the level of service recovery participation. Additionally, the internet banking service provider’s responsive and proactive customer orientation can influence customer service recovery experience, which further increases service recovery satisfaction. Recovery satisfaction can thus affect future intention toward using mobile banking. The moderating effect of transaction frequency was also confirmed. Theoretical and managerial implications are discussed

Ring Chromosome 7 Presenting with Intrauterine Growth Restriction and Multiple Anomalies

SummaryObjectiveRing chromosome 7 is a very rare chromosomal anomaly that may have a grave prognosis. Nevertheless, the clinical features associated with ring chromosome 7 are highly variable. Here, we report a case with ring chromosome 7 and the perinatal findings.Case ReportA 32-year-old, gravida 1, para 0, woman was referred to our hospital because of intrauterine growth restriction (IUGR) and oligohydramnios at 35 weeks of gestation. Prenatal ultrasound revealed a severe IUGR fetus presenting with multicystic kidney, hydronephrosis and oligohydramnios. At parturition, the birth weight of this male infant was 1,720 g, and a battery of anomalies were also noted, including imperforate anus, hypospadia, micropenis, right cryptorchidism, severe IUGR, multiple nevi on the forehead, shoulder and left thigh, brain atrophy, right multicystic kidney, and left mild hydronephrosis. Cytogenetic study from cord blood revealed a ring chromosome 7.ConclusionRing chromosome 7 is extremely rare and our case might be the 15th and youngest case in the medical literature. Our case had multicystic kidney and imperforate anus, which have not been reported previously. Prenatal diagnosis of ring chromosome 7 is very difficult. When fetuses present with severe IUGR, oligohydramnios and multicystic kidney, chromosomal aberrations should be kept in mind, and perinatal cytogenetic workup is warranted

Altered expression of protein tyrosine phosphatase, non-receptor type 22 isoforms in systemic lupus erythematosus

Introduction: A C-to-T single nucleotide polymorphism (SNP) located at position 1858 of human protein tyrosine phosphatase, non-receptor type 22 (PTPN22) complementary DNA (cDNA) is associated with an increased risk of systemic lupus erythematosus (SLE). How the overall activity of PTPN22 is regulated and how the expression of PTPN22 differs between healthy individuals and patients with lupus are poorly understood. Our objectives were to identify novel alternatively spliced forms of PTPN22 and to examine the expression of PTPN22 isoforms in healthy donors and patients with lupus. Methods: Various human PTPN22 isoforms were identified from the GenBank database or amplified directly from human T cells. The expression of these isoforms in primary T cells and macrophages was examined with real-time polymerase chain reaction. The function of the isoforms was determined with luciferase assays. Blood samples were collected from 49 subjects with SLE and 15 healthy controls. Correlation between the level of PTPN22 isoforms in peripheral blood and clinical features of SLE was examined with statistical analyses. Results: Human PTPN22 was expressed in several isoforms, which differed in their level of expression and subcellular localization. All isoforms except one were functionally interchangeable in regulating NFAT activity. SLE patients expressed higher levels of PTPN22 than healthy individuals and the levels of PTPN22 were negatively correlated with the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC-DI). Conclusions: The overall activity of PTPN22 is determined by the functional balance among all isoforms. The levels of PTPN22 isoforms in peripheral blood could represent a useful biomarker of SLE

Optical, Excitonic, and Electronic Properties of CH3NH3PbI3 Thin Films and Their Application in Photovoltaics

In the past two years, the highest power conversion efficiency of perovskite absorber (PA)–based photovoltaics has been 20.2%. The PA can be fabricated on flat substrates (for example, ZnO, TiO2, and PEDOT:PSS) using solution processes, which have a low-cost advantage in terms of industry production. In this report, the recent advances of PA-based photovoltaics will be mentioned. Then, the optoelectronic properties of PA, material fabrication, and photovoltaic performance will be discussed. On the other hand, we used scanning electron microscopy, two-dimensional X-ray diffractometer, and photoluminescence spectroscopy to investigate the fundamental properties of CH3NH3PbI3 thin films fabricated with and without toluene washing treatment, which provides an assessment of the development potential of PA-based photovoltaics

6-Mercaptopurine attenuates tumor necrosis factor-α production in microglia through Nur77-mediated transrepression and PI3K/Akt/mTOR signaling-mediated translational regulation

Physical interaction between Nur77 and p65. BV-2 cells were pretreated with 6-MP (50 μM) for 16 h followed by exposure to LPS (100 ng/ml) for 60 min. Nuclear extracts were harvested for immunoprecipitation (IP) experiments using anti-Nur77 and anti-p65 antibodies. Immunoblot (IB) analyses of the immunoprecipitates were performed using these antibodies. The immunoblots are representative of three independent experiments. (TIF 280 kb
