Analysis on Shuttle Bus Stop Service Performance Based on the User’s Perception The Case Study of Trans Bintaro, South Tangerang (Indonesia)

Shuttle bus is one of the mass transportation modes serving passengers from one point to another in a fast and accurate time. As passengers move from one point to another, a shuttle bus stop is considered to be an important factor which determines customer’s satisfaction and needs. This study investigates the service performance of Trans Bintaro shuttle bus stop in South Tangerang based on the users’ perception. Using qualitative method, performance is investigated based on the Importance Performance Analysis (IPA), and the customer satisfaction is measured based on the Customer Satisfaction Index (CSI). Data are collected through distributing questionnaires to shuttle bus customers to get their perception about the service performance. The study shows that only few quality service aspects such as safety, accessibility, and security of the bus stop are considered important, yet currently provide low service level. Based on the customer satisfaction analysis, accessibility to information plays crucial role at the shuttle bus stop. On the other hand, respondents see other aspects such as sitting and smoking areas are not crucial in determining customer satisfaction. These findings provide feedback to Bintaro Jaya Town Management in improving the service performance. Key-words: Bus Stop, Importance, Customer Satisfaction, Shuttle Bus Service.
The Digital Transformation of News Media and the Rise of Disinformation and Fake News

This report contains an overview of the relevant economic research literature on the digital transformation of news markets and the impact on the quality of news. It compares various definitions of fake news, including false news and other types of disinformation and finds that there is no consensus on this. It presents some survey data on consumer trust and quality perceptions of various sources of online news that indicate relatively high trust in legacy printed and broadcasted news publishers and lower trust in algorithm-driven news distribution channels such as aggregators and social media. Still, two thirds of consumers access news via these channels. More analytical empirical evidence on the online consumption of genuine and fake news shows that strong newspaper brands continue to attract large audiences from across the political spectrum for direct access to newspaper websites. Real news consumption on these sites dwarfs fake news consumption. Fake news travels faster and further on social media sites. Algorithm-driven news distribution platforms have reduced market entry costs and widened the market reach for news publishers and readers. At the same time, they separate the role of content editors and curators of news distribution. The latter becomes algorithm-driven, often with a view to maximize traffic and advertising revenue. That weakens the role of trusted editors as quality intermediaries and facilitates the distribution of false and fake news content. It might lead to news market failures. News distribution platforms have recently become aware of the need to correct for these potential failures. Non-regulatory initiatives such as fact-checking, enhanced media literacy and news media codes of conduct can also contribute.
Nuclear Matrix Interactions within the Sperm Genome (*)

Analysis of the haploid-expressed human PRM1 PRM2 TNP2 genic domain has revealed two regions of attachment to the sperm nuclear matrix. These sperm nuclear matrix attachment regions delimit the DNase I-sensitive domain of this haploid-expressed locus. The domain is intermediately associated with but not attached to the nuclear matrix. DNase I-sensitive genes within the mature sperm nucleus, such as protamine 1, protamine 2, transition protein 2, α-globin, and β-actin, display this intermediate affinity for the sperm nuclear matrix. This may denote their role in templating the male genome prior to fertilization, thus ensuring the formation of a viable male pronucleus during early embryonic development.
Selecting promising landmarks

Many approaches to visual servoing and mobile robot navigation are based on tracking feature points or landmarks in images, but not all features points are equally effective as landmarks. Here we develop methods for selecting within an image those landmarks which are both perceptually salient and visually distinctive, and consequently are readily recognized in a second image acquired from a different viewpoint. Empirically, we characterize the performance of the recognition method and then demonstrate that the selection process does in fact choose the landmarks which are more likely to be recognized.
Use of methyl malondialdehyde as an internal standard for malondialdehyde detection: validation by isotope-dilution gas chromatography-mass spectrometry.

Malondialdehyde (MDA), a compound derived from lipid peroxidation and from eicosanoid biosynthesis, exists in biological matrices both in the free form and bound to SH and/or NH2 groups of various biomolecules (1). Although other compounds (isoprostanes) have been proposed as more reliable indicators of oxidative damage (2), MDA is still widely used in clinical chemistry laboratories to monitor oxidative stress (3). Several methods have been developed to evaluate MDA in biological samples (1)(4), but the different analytical conditions used and the lack of a suitable internal standard have led to large discrepancies in measurements even at physiologic MDA concentrations in human plasma (5). We (6) recently reported a “reference method” for free and total plasma MDA quantification, as the phenylpyrazole derivative, by isotope-dilution gas chromatography–mass spectrometry (ID-GC-MS) with dideuterated MDA (d2-MDA) as internal standard. This method, used for clinical MDA detection (7)(8)(9), offers the possibility of validating other proposed internal standards that differ from MDA in structure, stability, and reactivity. Unfortunately, the major limitations of d2-MDA include its difficult synthesis (10) and that it is detectable only by GC-MS, a method not always available in clinical laboratories. A compound that appears to be more suitable as an internal standard is methyl malondialdehyde (MMDA) because it is structurally close to MDA, is absent from biological matrices, is easily obtainable from a commercial compound, and is detectable by common methods such as HPLC, GC, and capillary electrophoresis. MMDA was first evaluated as an internal standard for MDA determinations by Bull and Marnett (11), who unfortunately experienced difficulties in resolving the underivatized MDA and MMDA by HPLC. Recently, Claeson et al. (12) reported the use of MMDA as an internal standard for measurement of MDA in rat brain by capillary electrophoresis, …
NMR-based analysis of metabolites in urine provides rapid diagnosis and etiology of pneumonia.

Community-acquired pneumonia is an infection of the lower respiratory tract caused by bacteria, viruses, fungi and parasites. Globally, pneu monia is responsible for more deaths than any other infectious disease, and kills more children than AIDS, malaria and measles combined [1]. Indeed, even within the USA, pneumonia ranks as one of the leading causes of death. Unfortunately, diagnosis and identification of the causative agent for pneumonia has been difficult owing to the wide diversity of culpable pathogens coupled with inadequacies in current diagnostic methods [2–4]. Severe viral respiratory infections that have emerged in the past few years, such as the severe acute respiratory syndrome pandemic in 2002–2003 and the H1N1 pandemic in 2009, have focused attention on the need for rapid, accurate and cost-effective diagnostic tests to rapidly establish the causative pathogen(s) to enable better control of the spread of disease. In addition, viral infections can be superinfected by, or synergize with, bacterial infections, rendering diagnosis and management more complex. More rapid, accurate and comprehensive diagnosis would allow clinicians to focus on appropriate intervention(s), leading to a better clinical outcome for patients with reduced consumption of limited resources.
Impact of SNP array karyotyping on the diagnosis and the outcome of chronic myelomonocytic leukemia with low risk cytogenetic features or no metaphases

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic disorder with heterogeneous clinical, morphological and genetic characteristics. Clonal cytogenetic abnormalities are found in 20–30% of patients with CMML. Patients with low risk cytogenetic features (normal karyotype and isolated loss of Y chromosome) account for ∼80% of CMML patients and often fall into the low risk categories of CMML prognostic scores. We hypothesized that single nucleotide polymorphism arrays (SNP‐A) karyotyping could detect cryptic chromosomal alterations with prognostic impact in these subgroup of patients. SNP‐A were performed at diagnosis in 128 CMML patients with low risk karyotypes or uninformative results for conventional G‐banding cytogenetics (CC). Copy number alterations (CNAs) and regions of copy number neutral loss of heterozygosity (CNN‐LOH) were detected in 67% of patients. Recurrent CNAs included gains in regions 8p12 and 21q22 as well as losses in 10q21.1 and 12p13.2. Interstitial CNN‐LOHs were recurrently detected in the following regions: 4q24–4q35, 7q32.1–7q36.3, and 11q13.3–11q25. Statistical analysis showed that some of the alterations detected by SNP‐A associated with the patients' outcome. A shortened overall survival (OS) and progression free survival (PFS) was observed in cases where the affected size of the genome (considering CNAs and CNN‐LOHs) was >11 Mb. In addition, presence of interstitial CNN‐LOH was predictive of poor OS. Presence of CNAs (≥1) associated with poorer OS and PFS in the patients with myeloproliferative CMML. Overall, SNP‐A analysis increased the diagnostic yield in patients with low risk cytogenetic features or uninformative CC and added prognostic value to this subset of patients. Am. J.

A controlled trial of physician counseling to promote the adoption of physical activity.

BACKGROUND In accordance with one of the Year 2000 Health Objectives, the current study tests the efficacy of brief physician-based counseling to increase physical activity in sedentary patients in a nonrandomized controlled trial. METHODS Control and intervention physicians were matched on medical practice variables. Two hundred fifty-five apparently healthy, sedentary, adult patients were recruited from 17 physician offices (mean age = 39 years, 84% female, 28% ethnic minority). Intervention physicians delivered 3 to 5 min of structured physical activity counseling during a well visit or follow-up for a chronic condition. A health educator made a brief booster phone call to patients 2 weeks after receiving physician counseling. Self-reported physical activity and stage of change (i.e., behavioral readiness to adopt or maintain activity) were collected at baseline and at 4- to 6-week follow-up. Objective activity monitoring was conducted on a subsample. RESULTS Intervention patients reported increased walking more than control patients (+37 min/week vs. +7 min/week). There was a significant intervention effect on the activity monitor. Intervention participants also demonstrated a greater increase in readiness to adopt activity than control subjects. CONCLUSIONS Physician-based counseling for physical activity is efficacious in producing short-term increases in moderate physical activity among previously sedentary patients.
The Informational Role of Buyback Contracts

Manufacturers often offer retailers buyback contracts to reduce retailers’ inventory costs by repurchasing unsold inventory at a prespecified returns price. We examine the signaling role of buyback contracts when the retailer is less informed about either the manufacturer’s reliability of honoring the buyback commitment (e.g., for a small/less-established manufacturer) or its product’s market potential (e.g., for a national brand manufacturer). We find that these two situations yield contrasting buyback designs: the manufacturer must distort the wholesale and returns prices downward to signal higher reliability, but upward to signal higher market potential. Nevertheless, the signaling mechanism in both cases hinges on suitably distorting the manufacturer’s returns cost (i.e., the cost of repurchasing a retailer’s unsold inventory) by influencing the retailer’s regular stock (i.e., the portion of inventory carried to meet average demand) and safety stock (i.e., the extra inventory carried to meet potential high demand). Notably, although prior research has highlighted the signaling role of the wholesale price, we show how and why, in a channel with inventory, the returns price plays a relatively more important role. In particular, efficient signaling entails that the returns price is used to distort the manufacturer’s returns cost, whereas the wholesale price is used only to mitigate the resulting distortion in the retailer’s order quantity. In fact, the returns price emerges as a more efficient signaling instrument and reverses the direction of wholesale price distortion from what is necessary if wholesale price alone is used to signal. We also examine the implications when the two dimensions of manufacturer’s private information are correlated. This paper was accepted by Juanjuan Zhang, marketing.
Reliable Distance Vector routing protocol to handle Blackhole and Selfish (RDVBS) nodes in Ad hoc Networks

Properties of Mobile Ad hoc Networks (MANETs) present major vulnerabilities in security. The threats considered in MANETs may be due to maliciousness of a node that intentionally disrupts the network by using variety of attacks and/or due to selfishness of the node which does not perform certain operations due to a wish to save power. None of the existing algorithms to mitigate black hole attacks handles selfish nodes. We present a first such algorithm which handles blacknode attack as well as selfish nodes. A co-operative security scheme called Reliable Ad hoc On-demand Distance Vector routing protocol has been proposed to solve the problem of attack by Blackhole node as well as Selfish behavior (RDVBS) . RDVBS behaves like AODV in the absence of attack with only a slight increase in the routing overhead and, detects and isolates black nodes and selfish nodes in the presence of attack. It also recovers from the attack when a black node leaves the network or a selfish node becomes good. Our protocol is also superior to the previous known algorithms in terms of routing overhead. The protocol also handles multiple and cooperative black nodes.
Collision avoidance for safe structure inspection with multirotor UAV

The multirotor UAVs are being integrated into a wide range of application scenarios due to maneuverability in 3D, versatility and reasonable payload of sensors. One of the application scenarios is the inspection of structures where the human intervention is difficult or unsafe and the UAV can provide an improvement of the collected data. At the same time introduce challenges due to low altitude missions and also the fact of being manually operated without line of sight. In order to overcome these issues, this paper presents a LiDAR-based real-time collision avoidance algorithm, denoted by Escape Elliptical Search Point with the ability to be integrated into autonomous and manned modes of operation. The algorithm was validated in a simulation environment developed in Gazebo and also in a mixed environment composed by a real robot in an outdoor scenario and simulated obstacle and LiDAR.
Tryptophan auxotroph mutants suppress the superroot2 phenotypes, modulating IAA biosynthesis in Arabidopsis.

Plant phytohormone, Indole-3-acetic acid (IAA), is synthesized by tryptophan (trp) dependent and independent pathway. Here we report that tryptophan auxotroph mutants completely suppressed the abnormalities of auxin over production mutant, superroot2. SUR2 is considered to modulate Trp dependent pathway, resulting IAA accumulation in Arabidopsis. Tryptophan auxotroph mutants showed hyper-sensitivity to the auxin polar transport inhibitor, NPA, on the phenotype of reduced gravitropism. These results together with the results of histochemical analyses, tryptophan auxotroph mutants seem to have a complete defect in Trp dependent IAA biosynthesis pathway, and it is also suggested that the Trp dependent pathway is responsible for the normal root gravitropism.
The Role of Social Influence in Purchasing Sports Apparel

The marketing of sports apparel is competitive with large amounts of advertising dollars spent in influencing consumer choice. The aim of this study is to establish whether a consumer is susceptible to social influence in the purchase of sports apparel. In particular, the study aims to establish if there is any difference between consumers of different genders and levels of sports involvement. A convenience sample of 116 respondents found that consumers are susceptible to informational and utilitarian influence but not value-expressive influence. The findings further suggest that consumers of the male gender and who are highly involved in sports are more likely to be influenced by informational influence as compared to consumers who are female and who are less involved in sports.
Impact of Single Nucleotide Polymorphism of TGF-β1 Gene (SNP-Codon10) on Hepatocellular Carcinoma Risk in Egyptian Patients Following HCV Infection

TGF-β1 is a cytokine producing extracellular matrix. We evaluated TGF-β1 gene polymorphism at codon 10 and the risk of HCC in Egyptian patients with HCV infection. TGF-β1 gene polymorphism was performed by the amplification refractory mutation system (ARMS-PCR). A significant difference in allelic frequency between control and HCV patients (p = 0.05). Logistic regression showed that the load of HCV-RNA is significantly predictive of the occurrence of HCC (p <0.001, OR=1.000). A significant difference of serum AFP among the three genotypes (p=0.04), particularly between CT and TT genotypic patients (p=0.01), indicating a relationship between T allele and incidence of HCC. This may enables us to determine the susceptibility to HCC among high risk groups and to provide these individuals with effective measures for early prevention or intervention.
Brain activation patterns elicited by the `Faces Symbol Test' — a pilot fMRI study

The Faces Symbol Test (FST) has recently been proposed as a brief and patient-friendly screening instrument for the assessment of cognitive dysfunction in patients with multiple sclerosis (MS). However, in contrast to well-established MS screening tests such as the Paced Auditory Serial Addition Test, the neural correlates of the FST have not been investigated so far. In the present study, we developed a functional MRI (fMRI) version of the FST to provide first data on brain regions and networks involved in this test. A sample of 19 healthy participants completed a version of the FST adapted for fMRI, requiring matching of faces and symbols in a multiple choice test and two further experimental conditions drawing on cognitive subcomponents (face matching and symbol matching). Imaging data showed a differential involvement of a fronto-parieto-occipital network in the three conditions. The most demanding FST condition elicited brain activation patterns related with sustained attention and executive control. These results suggest that the FST recruits brain networks critical for higher-order cognitive functions often impaired in MS patients. Multiple Sclerosis 2008; 14: 354—363. http://msj.sagepub. com
Two Males with SRY-Positive 46,XX Testicular Disorder of Sex Development

The 46,XX testicular disorder of sex development (46,XX testicular DSD) is a rare phenotype associated with disorder of the sex chromosomes. We describe the clinical, molecular, and cytogenetic findings of a 16- and a 30-year-old male patient with sex-determining region Y (SRY)-positive 46,XX testicular DSD. Chromosomal analysis revealed 46,XX karyotype. Fluorescence in situ hybridization (FISH) showed the SRY region translocated to the short arm of the X chromosome. The presence of the SRY gene was also confirmed by polymerase chain reaction (PCR). The X chromosome inactivation (XCI) assay showed that both patients have a random pattern of X chromosome inactivation. This report compares the symptoms and features of the SRY-positive 46,XX testicular DSD patients.
Metabolic rate in the right amygdala predicts negative affect in depressed patients

THE role of the amygdala in major depression was investigated. Resting regional cerebral metabolic rate (rCMRglu) was measured with [18 F]fluorodeoxyglucose positron emission tomography (PET) in two samples of subjects using two different PET cameras. The samples consisted of 10 and 17 medication-free depressives and 11 and 13 controls, respectively. Using coregistration of PET and magnetic resonance images, regions were individually delineated for the amygdala and thalamus, the latter of which was used as a control region. Within the depressed groups, right amygdalar rCMRglu was positively correlated with negative affect. Thalamic rCMRglu was not related to negative affect, and amygdalar rCMRglu accounted for a significant portion of variance in depressives' negative affect scores over and above the contribution of thalamic rCMRglu.
Direct and moderating effects of organizational factors on system usage in colleges: a resource-based perspective

Colleges as a non-profit organization engaged in the educational sector have a crucial role, especially in emerging countries. Significant improvement can be achieved by continuously strengthening the information system infrastructure. Prior studies mentioned the system implementation is tricky because it involves not only hardware and software but also users and operational procedures. The investment of information system poses challenges for management. The system failure can be the grave of an organization. Therefore, the end-users participation becomes acute that puts organizational factors have to be considered. This study aims to examine and analyze the information system success model by adding the existence of facilitating condition, institutional pressure, and incentives as organizational factors. Data were obtained through questionnaires filled by the users of colleges’ system. The results found that two constructs of organizational factors including facilitating condition and institutional pressure were able to increase the role of system usage to organization performance. Managers have to be proactive to motivate the end-users by designing better organizational factors and the future study may improve the construction of these factors.
