A NEW PERSPECTIVE ON PORT SUPPLY CHAIN MANAGEMENT ACCORDING TO THE SERVICE DOMINANT LOGIC

PURPOSE OF THE PAPER – The increasing role of ports in the whole logistics system invites a more detailed examination of port supply chain management (Christopher, 1992; Meersman and Van de Voorde, 1996; Coyle et al., 2003; De Martino and Morvillo, 2009). The purpose of this paper is to provide a new perspective on port supply chain management according to the Service Dominant logic (S-D logic) perspective (Lusch et al., 2010; Lusch, 2011). Thus, the concepts of service, value co-creation, value propositions, operant resources, networks, service ecosystems and information technology are explored through a case study approach. APPROACH – A systematic analysis of the current supply chain (SCM) and port-related literature is carried out through the lens of the value co-creation process (actors, resources, actions for practice/service development and value). Drawing from the Service Dominant Logic perspective (Vargo and Lusch, 2008; Vargo, 2008; Gummesson et al., 2010) and the Service Science, this paper offers a more complete understanding of SCM in an innovative way which potentially lead to co-create value. The study takes a qualitative approach adopting a case study (Yin, 2003) to understand and explain the role of S-D Logic in the conceptualization of port supply chain management. FINDINGS – The adoption of S-D logic perspective to port supply chain management enables identifying a system of value co-creation and competitiveness development, individualized according to the key stakeholders involved and the purpose it is created for. As this paper demonstrates, the port supply chain is re-conceptualized as a network of service systems each representing distinct (mostly operant) resource according to the service-dominant logic perspective (Lusch and Vargo, 2006). PRACTICAL IMPLICATIONS – Hence, the main practical implication of this paper is the definition of a value co-creation process as a suitable perspective to develop ports’ competitiveness. The use of the model of S-D logic enables to design a comprehensive framework which allows planning the creation of competitive supply chains. ORIGINALITY/VALUE – The study represents a first attempt to analyse relations between port supply chain management according to the S-D logic perspective. This enables a more rigorous and comprehensive approach to understand ports’ competitiveness development. TYPE OF PAPER – Case study paper/Research paper.

Team participation and online gamer loyalty

Online games have emerged as popular computer applications and gamer loyalty is vital to game providers, since online gamers frequently switch between games. Online gamers often participate in teams also. This study investigates whether and how team participation improves loyalty. We utilized a cross-sectional design and an online survey, with 546 valid responses from online game subjects. Confirmatory factor analysis was applied to assess measurement reliability and validity directly, and structural equation modeling was utilized to test our hypotheses. The results indicate that participation in teams motivates online gamers to adhere to team norms and satisfies their social needs, also enhancing their loyalty. The contribution of this research is the introduction of social norms to explain online gamer loyalty. 2013 Elsevier B.V. All rights reserved.
Predicting Preterm Birth Based on Maternal and Fetal Data

Preterm birth is “a birth which takes place after at least 20, but less than 37, completed weeks of gestation. This includes both live births, and stillbirths” [15]. Preterm birth may cause problems such as perinatal mortality, serious neonatal morbidity and moderate to severe childhood disability. Between 6-10% of all births in Western countries are preterm and preterm deaths are the cause for more than two-third of all perinatal deaths [9]. While the recent advances in neonatal medicine has greatly increase the chance of survival of infants born after 20 weeks of gestation, these infants still frequently suffer from lifelong handicaps, and their care can exceed a million dollars during the first year of life [5 as cited in 6]. As a first step for preventing preterm birth, decision support tools are needed to help doctors predict preterm birth [6].
Revision Rhinoplasty for Short Noses in the Asian Population.

IMPORTANCE
Short nose, especially postoperative short nose in Asian patients, remains a challenging problem for plastic surgeons.


OBJECTIVE
To determine the outcomes of revision rhinoplasty of postoperative short noses in Asian patients.


DESIGN, SETTING, AND PARTICIPANTS
We performed a retrospective medical record review of 41 Asian patients with postoperative short nose who underwent revision rhinoplasty in a tertiary care referral center in South Korea from October 1, 2006, through August 31, 2014.


MAIN OUTCOMES AND MEASURES
Patient demographic, surgical technique, graft use, anthropometric measurement, complication, and aesthetic outcome assessment data were retrieved.


RESULTS
The 41 enrolled patients were a mean (SD) of 36.5 (12.6) years old. There were 16 men and 25 women. The most commonly used dorsal graft in the previous rhinoplasty was silicone, followed by fascia with or without cartilage. Various surgical techniques were applied, including septal reconstruction, cartilage flap technique, tip surgery, lateral compartment correction, and dorsal augmentation. Autologous costal cartilage was the most commonly used septal reconstruction material. Eleven patients (27%) developed postoperative complications, including infection, nostril asymmetry, and pollybeak deformity. Revision rhinoplasty yielded statistically significant improvements in nasal length (increase of 12.0%, P < .001), nasal tip projection (increase of 13.4%, P < .001), nasofrontal angle (decrease of 2.39°, P = .04), nasolabial angle (decrease of 7.62°, P < .001), and columella-lobular angle (increase of 3.25°, P < .001). More than 90% (37) of the patients were judged to have good or excellent aesthetic results.


CONCLUSIONS AND RELEVANCE
Correction of postoperative short nose in Asian patients requires complicated surgery that usually involves more than one kind of surgical technique. Complications are not uncommon, and patients should be informed of this before surgery.

Sensorless operation of active damping methods for three-phase PWM converters

The three-phase PWM (active) rectifiers with bi-directional power flow and regulation of power factor to unity become to be more popular. These converters are connected to the supply network through inductance or LCL filter, what ensures attenuation of switching harmonics. LCL filter is more effective and reduce harmonic distortion at lower switching frequency, however such solution brings stability problems. In order to assure stable operation either a damping resistor or active damping algorithm has to be used. However, extra resistor causes additional losses and active damping algorithm usually needs extra sensors. This paper shows possibility to eliminate AC voltage sensors in two active damping methods making them more reliable and inexpensive.
Child Maltreatment and Academic Performance of Senior Secondary School Students in Ibadan, Nigeria

This research was carried out to examine the effect of child maltreatment on academic performance of Senior Secondary School students in Ibadan, Nigeria. The Questionnaire was the instrument of data collection, administered to five hundred and twelve students selected randomly in two local government areas. A hypothesis that “there is no significant relationship between child maltreatment and academic performance” was formulated. This was tested using multiple regression analysis and the result indicated that there is significant relationship between child maltreatment and academic performance. It is recommended among others that the government should intensify efforts towards eradication of poverty among the populace, so as to enable parents have enough capital to provide for their children. Also, single parenthood should be discouraged as it exposes children to all kinds of maltreatment.
A prospective randomized study to evaluate the renoprotective action of beating heart coronary surgery in low risk patients q

Objectives: Cardiopulmonary bypass (CPB) is widely regarded as an important contributor to renal failure, a well recognized complication following coronary artery surgery (coronary artery bypass grafting (CABG)). Anecdotally off-pump coronary surgery (OPCAB) is considered renoprotective. We examine the extent of renal glomerular and tubular injury in low-risk patients undergoing either OPCAB or on-pump coronary artery bypass (ONCAB). Methods: Forty low-risk patients with normal preoperative cardiac and renal functions awaiting elective CABG were prospectively randomized into those undergoing OPCAB (n 1⁄4 20) and ONCAB (n 1⁄4 20). Glomerular and tubular injury were measured respectively by urinary excretion of microalbumin and retinol binding protein (RBP) indexed to creatinine (Cr). Daily measurements were taken from admission to postoperative day 5. Fluid balance, serum Cr and blood urea were also monitored. Results: No mortality or renal complication were observed. Both groups had similar demographic makeup, Parsonnet score, functional status and extent of coronary revascularization (2.1 ^ 1.0 vs. 2.5 ^ 0.7 grafts; P 1⁄4 0:08). Serum Cr and blood urea remained normal in both groups throughout the study. A significant and similar rise in urinary RBP:Cr occurred in both groups peaking on day 1 (3183 ^ 2534 vs. 4035 ^ 4079; P 1⁄4 0:43) before reapproximating baseline levels. These trends were also observed with urinary microalbumin:Cr (5.05 ^ 2.66 vs. 6.77 ^ 5.76; P 1⁄4 0:22). Group B patients had a significantly more negative fluid balance on postoperative day 2 (2183 ^ 1118 vs. 637 ^ 847 ml; P 1⁄4 0:03). Conclusions: Although renal complication or serum markers of kidney dysfunction were absent, sensitive indicators revealed significant and similar injury to renal tubules and glomeruli following either OPCAB or ONCAB. These results suggest that avoidance of CPB does not offer additional renoprotection to patients at low risk of perioperative renal insult during CABG. q 2002 Elsevier Science B.V.

Mass media exposure, social stratification, and tobacco consumption among Nigerian adults

Mass media exposure is a strong determinant of tobacco use yet little is known about this relationship in African countries. We explored socio-demographic and socio-contextual correlates of tobacco consumption and associations between mass media exposure, gender and the use of any and various forms of tobacco among Nigerians. The study included 47,805 adults from the cross-sectional and nationally representative Nigeria demographic and health survey 2008. Weighted binary logistic models predicted any tobacco use whereas weighted multinomial logistic models predicted smoking and smokeless tobacco, all compared with no tobacco use. Approximately 4.2% of Nigerian adults used tobacco—2.7% smoked tobacco whereas 1.5% used smokeless tobacco. Tobacco use was more prevalent among men than women (12% vs. 0.6%; p value <0.0001). Gender modified the associations between tobacco use and radio exposure or TV exposure (p values ranged = 0.02–0.05). Among men, some radio exposure and high radio exposure were associated with increased odds of any tobacco use, compared with no radio exposure. Among men, infrequently reading newspapers/magazines and frequently reading newspapers/magazines were associated with higher odds of smokeless tobacco use, compared with not reading newspapers/magazines. Among women, infrequently reading newspapers/magazines was associated with reduced odds of smokeless tobacco use, compared with not reading newspaper/magazines. The relationships between mass media exposure and tobacco consumption differed by gender and were more pronounced among men. Research on radio programs may help to form policies that can address tobacco use among Nigerian men.
Psychometric Evaluation of a Treatment Acceptance Measure for Use in Patients Receiving Treatment via Subcutaneous Injection.

BACKGROUND
Alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, significantly reduces low-density lipoprotein cholesterol, but requires subcutaneous injections rather than oral pills. To measure patients' acceptance of this treatment modality, a new patient-reported outcome, the Injection-Treatment Acceptance Questionnaire (I-TAQ), was developed.


OBJECTIVES
To psychometrically evaluate the I-TAQ with patients at high risk of cardiovascular events receiving alirocumab.


METHODS
The 22-item, 5-domain I-TAQ was administered cross-sectionally to 151 patients enrolled in alirocumab clinical trials. Item response distributions, factor and multitrait analyses, interitem correlations, correlations with an existing measure of acceptance (convergent validity), and comparison of known-groups were performed to assess the I-TAQ's psychometric properties.


RESULTS
Completion rates were high, with no patients missing more than two items and 91.4% missing no data. All items displayed high ceiling effects (>30%) because of high treatment acceptance. Factor analysis supported the a priori hypothesized item-domain structure with good fit indices (root mean square error approximation = 0.070; comparative fit index = 0.988) and high factor loadings. All items demonstrated item convergent validity (item-scale correlation ≥0.40), except for the side effects domain, which was limited by small numbers (n = 46). Almost all items correlated most highly with the domain to which they were assigned (item discriminant validity). Internal reliability was acceptable for all domains (Cronbach α range 0.72-0.88) and convergent validity was supported by a logical pattern of correlations with the Chronic Treatment Acceptance Questionnaire.


CONCLUSIONS
These findings provide initial evidence of validity and reliability for the I-TAQ in patients treated with subcutaneous alirocumab. The I-TAQ could prove to be a valuable patient-reported outcome for therapies requiring subcutaneous injection.
A Decision Support System for Global Team Management: Expert Evaluation

Context: The literature is rich in examples of both successful and failed global software development projects. However, practitioners do not have the time to wade through the many recommendations to work out which ones apply to them. To this end, we developed a prototype Decision Support System (DSS) for Global Teaming (GT), with the goal of making research results available to practitioners. Aims: We want the system we build to be based on the real needs of practitioners: the end users of our system. Therefore the aim of this study is to assess the usefulness and usability of our proof-of-concept in order to create a tool that is actually used by practitioners. Method: Twelve experts in GSD evaluated our system. Each individual participant tested the system and completed a short usability questionnaire. Results: Feedback on the prototype DSS was positive. All experts supported the concept, although many suggested areas that could be improved. Both expert practitioners and researchers participated, providing different perspectives on what we need to do to improve the system. Conclusion: Involving both practitioners (users) and researchers in the evaluation elicited a range of useful feedback, providing useful insights that might not have emerged had we focused on one or the other group. However, even when we implement recommended changes, we still need to persuade practitioner to adopt the new tool.
Deep variance network: An iterative, improved CNN framework for unbalanced training datasets

Convolutional neural network (CNN) has demonstrated its superior ability to achieve amazing accuracy in computer vision field. Nevertheless, for practical domain-specific image recognition tasks, it still remains difficult to obtain massive high-quality labeled datasets due to the strong requirements for extensive, tedious manual processing. Inspired by the well-known observation that human brain can accurately recognize objects without relying on massive congeneric examples, we propose a novel deep variance network (DVN) to further enhance the generalization ability of CNN in this paper, which could still produce higher recognition accuracy even with unbalanced training datasets than original CNN. The key idea of our DVN is built upon the intrinsic exploitation of inter-class homogeneity and intra-class heterogeneity. Towards such goal, we make the first attempt to incorporate a hierarchical Bayesian model into the powerful CNN framework, which can transfer the joint feature distribution from certain object’s complete training dataset to other object’s incomplete training dataset in an iterative way. In each training cycle, the CNNresulted features are clustered into discrimination-related subspaces to guide the learning and adaptive adjustment of homogeneity and heterogeneity over unbalanced training datasets. In practice, we furnish several state-of-the-art deep networks with our proposed DVN, and conduct extensive experiments and comprehensive evaluations over CIFAR-10, MNIST, and SVHN benchmarks. The experiments have shown that, most of the furnished deep networks can benefit from our DVN, wherein they gain at most 6.9% accuracy improvement over CIFAR-10 benchmark, 52.83% error reduction over MNIST benchmark, and an improvement of 6.2% over SVHN datasets. © 2018 Elsevier Ltd.

Parent Training for Childhood Anxiety Disorders: The SPACE Program☆

Anxiety disorders are the most prevalent disorders of childhood and adolescence. Cognitive behavioral therapy (CBT) for anxiety poses a challenge for clinicians as it requires active client participation, and many children either decline or do not adequately comply with treatment. In addition, even after treatment with CBT, up to 50% of children remain symptomatic, and many still meet diagnostic criteria. Parent-directed clinical work has been advocated as a potential enhancer of treatment outcomes, and exclusively parent-based interventions might replace child treatment when the child is reluctant. However, parent involvement has yet to be shown to significantly improve outcomes, relative to child-only therapy. Studies so far have focused mainly on including parents in children’s therapy, training parents as lay therapists, or teaching parenting skills. Parent training focused on parental behaviors specific to childhood anxiety, such as family accommodation, may be more effective. In this treatment development report we present the theoretical foundation, structure, and strategies of a novel parent-based intervention for childhood anxiety disorders. We will also present the results of an open trial of the treatment, with an emphasis on feasibility, acceptability, and initial outcomes. Participants in the trial were parents of 10 children, aged 9 to 13. Children had declined individual child treatment. Multiple excerpts from the treatment manual are included with the hope of “bringing the treatment to life” and conveying a rich sense of the therapeutic process. Parents participated in 10 weekly sessions. Significant improvement was reported in child anxiety and family accommodation as well as in the child’s motivation for individual treatment. No parents dropped out and satisfaction was high. The SPACE Program (Supportive Parenting for Anxious Childhood Emotions) is a novel, manualized parent-based intervention that is feasible and acceptable and may be effective in improving childhood anxiety.
Neural Acupuncture Unit: A New Concept for Interpreting Effects and Mechanisms of Acupuncture

When an acupuncture needle is inserted into a designated point on the body and mechanical or electrical stimulation is delivered, various neural and neuroactive components are activated. The collection of the activated neural and neuroactive components distributed in the skin, muscle, and connective tissues surrounding the inserted needle is defined as a neural acupuncture unit (NAU). The traditionally defined acupoints represent an anatomical landmark system that indicates local sites where NAUs may contain relatively dense and concentrated neural and neuroactive components, upon which acupuncture stimulation would elicit a more efficient therapeutic response. The NAU-based local mechanisms of biochemical and biophysical reactions play an important role in acupuncture-induced analgesia. Different properties of NAUs are associated with different components of needling sensation. There exist several central pathways to convey NAU-induced acupuncture signals, Electroacupuncture (EA) frequency-specific neurochemical effects are related to different peripheral and central pathways transmitting afferent signals from different frequency of NAU stimulation. More widespread and intense neuroimaging responses of brain regions to acupuncture may be a consequence of more efficient NAU stimulation modes. The introduction of the conception of NAU provides a new theoretical approach to interpreting effects and mechanisms of acupuncture in modern biomedical knowledge framework.
Protecting Location Privacy for Task Allocation in Ad Hoc Mobile Cloud Computing

Mobile cloud computing (MCC) is an emerging cloud-computing paradigm that integrates cloud computing and mobile computing to enable many useful mobile applications. However, the large-scale deployment of MCC is hindered by the concerns on possible privacy leakage. In this paper, we investigate the privacy issues in the ad hoc MCC, and propose a framework that can protect the location privacy when allocating tasks to mobile devices. Our mechanism is based on differential privacy and geocast, and allows mobile devices to contribute their resources to the ad hoc mobile cloud without leaking their location information. We develop analytical models and task allocation strategies that balance privacy, utility, and system overhead in an ad hoc mobile cloud. We also conduct extensive experiments based on real-world data sets, and the results show that our framework can protect location privacy for mobile devices while providing effective services with low system overhead.
