Big Data, Big Insights? Advancing Service Innovation and Design With Machine Learning

Service innovation is intertwined with service design, and knowledge from both fields should be integrated to advance theoretical and normative insights. However, studies bridging service innovation and service design are in their infancy. This is because the body of service innovation and service design research is large and heterogeneous, which makes it difficult, if not impossible, for any human to read and understand its entire content and to delineate appropriate guidelines on how to broaden the scope of either field. Our work addresses this challenge by presenting the first application of topic modeling, a type of machine learning, to review and analyze currently available service innovation and service design research (n = 641 articles with 10,543 pages of written text or 4,119,747 words). We provide an empirical contribution to service research by identifying and analyzing 69 distinct research topics in the published text corpus, a theoretical contribution by delineating an extensive research agenda consisting of four research directions and 12 operationalizable guidelines to facilitate cross-fertilization between the two fields, and a methodological contribution by introducing and demonstrating the applicability of topic modeling and machine learning as a novel type of big data analytics to our discipline.
Organizational and Methodological Approaches to Development of Accounting Policy for Formation of Integrated Accounting of Interrelated Agricultural Companies

The purpose of the article is to determine advantages and drawbacks of existing organizational and methodological approaches to development of accounting policy and develop optimal approach to formation of integrated accounting of interrelated agricultural enterprises. For this purpose, the article uses methods of problem and comparative analysis, method of optimization, and methods of graphical presentation of information. The authors conduct comparative analysis of existing organizational and methodological approaches to development of accounting policy of enterprise and develop optimal approach to formation of integrated accounting of interrelated agricultural enterprises. As a result of the research, the authors come to the conclusion that Russian and international approach to development of accounting policy differ from each other, but neither of these approaches is optimal for formation of integrated accounting of interrelated agricultural enterprises. The developed optimal approach to formation of integrated accounting allows unifying the process of development of accounting policy of enterprise and thus is the best for interrelated agricultural enterprises. This approach is oriented at consumers, due to which it is able not only to simplify the process of formation of corporate accounting of interrelated agricultural enterprises but to turn it into the factor of their competitiveness.
NONUNIFORM DISTRIBUTION OF BLOOD FLOW AND GRADIENTS OF OXYGEN TENSION WITHIN THE HEART.

Myocardial tissue pressure increases from epicardium to endocardium, and in the deeper layers exceeds ventricular blood pressure during one-third of the cardiac cycle (21). The effect of this tissue pressure gradient on local blood flow was studied using the depot clearance technique. Blood flow was found to be at least 25% lower in the deep regions as compared with superficial ones. With total coronary inflow held constant, vagal arrest of the heart removed the tissue pressure gradient, and simultaneously redistributed flow from superficial to deeper layers. We conclude that the gradient in tissue pressure, and hence in the extravascular component of coronary resistance, is at least in part, the cause of the nonhomogeneous blood flow across the wall. By use of the oxygen cathode, a gradient of oxygen tensions was observed which paralleled the blood flow gradient; mean oxygen tension in the subepicardium averaged twice that in the subendocardium. The gradient in oxygen tension appears to be of sufficient magnitude to determine a transmural gradient in aerobic metabolism.

Over the past decades, there has been a continuous growing demand for faster, safer, and more intelligent wireless networks. Requirements for next generation cellular networks include higher data rates and scalability, lower latency and energy consumption, and improved connectivity, reliability, and security. Many key enabling technologies have been proposed as solutions to meet these requirements, such as ultra-densification, wireless software defined networking, massive MIMO, and millimeter wave technology [1]. This survey will be focused on proposed changes in cellular architecture, specifically Ultra Dense Networks (UDNs), that aim at solving the challenges of future cellular networks.
Internet of Things Connected Smart Farm Solutions for Sustainable Agro-ecological and Rural Development

Climate smart agriculture is a matter of serious concern for the global policy makers. Various International Organizations, Government Agencies and Corporate Houses are working together in this direction. Technological interventions in the field of agriculture and food production are required to improve the quality and quantity of farm products with reduced production risk. It also reduces environmental cost of agricultural production. Recent developments in the fields of smart transducers (IEEE 1451) in close association with Low Power Wireless Personal Area Network (6LoWPAN) standard, are offering many innovative Agro-ICT solutions for various agricultural applications focusing towards sustainable agro-ecological and rural development. In such applications Internet of Things (IoT) connected farm equipments also play an important role in acquisition, processing, analysis and dissemination of information. IoT connectivity extends the concept of ubiquitous computing with heterogeneous smart devices integrated with interoperable communication technologies. The motive of this paper is to investigate the State of Art Agricultural information systems that are used to provide flexible control mechanism for agro-ecological resource management.
Amniotic Fluid for Ex Vivo Skin Preservation: A Comparative Study of Tissue Preservation Solutions

AbstractEx vivo skin preservation is important for skin banks, burn centers, and in research; however, the optimal preservation solution is not known. Human amniotic fluid (HAF), in addition to its role in fetal wound healing, has promise as an effective and readily available preservation solution. The purpose of this study was to compare the efficacy of several solutions, including HAF, in full-thickness skin preservation. Human amniotic fluid was obtained from patients undergoing amniocentesis. Full-thickness skin obtained during abdominoplasty was divided into 1-cm2 samples. These specimens were preserved in either saline, HAF from a single patient, pooled HAF, University of Wisconsin solution, or custodial histidine-tryptophan-ketoglutarate solution at 4°C. There were 5 samples in each group. Specimens were examined for keratinocyte survival at 7, 14, 21, 28, and 35 days using the trypan blue assay. The first 200 cells identified were counted to calculate the degree of cell death. Comparisons were made between the groups, and a multivariable repeated-measures analysis was performed to determine statistical significance, which was defined as P < 0.05. The individual and pooled HAF showed greater keratinocyte survival than the other solutions, at each time point. The difference was statistically significant (P < 0.05) when compared to saline and custodial solution but not statistically significant when compared to University of Wisconsin solution. When used as a tissue preservation solution, HAF produces superior keratinocyte survival than several commercially available solutions. Amniotic fluid, nature’s tissue preservation solution, may be an inexpensive, readily available alternative for use in skin banks, burn centers, and research.
System identification from partial samples: Non-asymptotic analysis

The problem of learning the parameters of a vector autoregressive (VAR) process from partial random measurements is considered. This setting arises due to missing data or data corrupted by multiplicative bounded noise. We present an estimator of the covariance matrix of the evolving state-vector from its partial noisy observations. We analyze the non-asymptotic behavior of this estimator and provide an upper bound for its convergence rate. This expression shows that the effect of partial observations on the first order convergence rate is equivalent to reducing the sample size to the average number of observations viewed, implying that our estimator is order-optimal. We then present and analyze two techniques to recover the VAR parameters from the estimated covariance matrix applicable in dense and in sparse high-dimensional settings. We demonstrate the applicability of our estimation techniques in joint state and system identification of a stable linear dynamic system with random inputs.
Subnational Infrastructure Investment in OECD Countries: Trends and Key Governance Levers

Public investment is one of the fiscal tools with the strongest impacts on growth over the long term. However, public investment is in decline compared to the period prior to the 2008 global financial crisis in many OECD countries, and particularly in the EU. The main explanation for the decreased resources available for investment comes from the expenditure side. Subnational governments (SNGs)—defined as all levels of government (regional and local) below the national level, are responsible for a large share of public investment: on average, around 60 per cent in the OECD. Most of this public investment goes to infrastructure. This particular role of SNGs poses specific challenges for both the financing and governance of infrastructure investment. This paper focuses on subnational public investment in OECD countries and the EU, and shows that subnational governments have decreased their capital expenditures after 2010. This adjustment has been larger than at the central government level. The paper argues that only a limited diversification of public investment financing has occurred since 2010. The paper also argues that, beyond the sheer volume of investment spending, the governance of subnational investment is essential to efficient public investment. Based on a 2015 survey of 255 subnational governments in the EU, this paper explores specific challenges that subnational governments encounter in managing capital expenditures, , and possible ways to improve the quality of governance of subnational investments.
The histopathological and clinical features of irradiated and nonirradiated temporal paragangliomas

This study was undertaken to determine the effects of radiation on temporal paragangliomas. The histological features were assessed in a blind fashion from 20 surgical specimens obtained from 20 patients, half of whom received radiotherapy. All patients had progressive temporal paragangliomas and were selected on a random basis for this study. The derived data clearly identify the unpredictable response of these tumors to radiation and supports our contention that surgery is the preferred form of treatment for temporal paragangliomas even after radiation therapy. Analysis of clinical histories reveals that previous radiation therapy is associated with a greater operative blood loss and a longer mean postoperative hospital stay due to delayed healing. Despite this, there was no mortality or serious morbidity from surgery.
Yazilim Guvenlik Testi: Bir Sistematik Literatur Haritalamasi

Security testing of software systems such as mobile applications, web applications, computer applications and server applications has become an essential activity. As the area of software security testing (SST) has matured and the number of studies has increased, systematically categorizing the current state-of-the-art is important. In this paper, we classify the established knowledge in this area through a systematic mapping study. In the scope of the study, three sets of mapping questions are posed, research keywords are selected, inclusion and exclusion criteria is defined, a classification schema is devel-
Analysis of the expression of biomarkers in urinary bladder cancer using a tissue microarray

Dysregulation of Akt, PTEN, Drg‐1, Cx‐26, and L‐plastin expression appear to be important in the progression of various cancers. Their expression in bladder cancer has not been well characterized. To assess the expression of these genes and their relationship to the outcome of bladder cancer, we used a bladder cancer tissue microarray (TMA) of 251 transitional cell carcinomas. We quantitated immunohistochemical staining of each protein using both automated and manual methods and correlated the expression levels with the clinicopathologic characteristics of the tumor and patient survival. Overall, the results from both automated and manual analyses were similar. We found a significant correlation between the expression of PTEN, Cx‐26 and L‐plastin with known clinically important pathologic features of bladder cancer (tumor grade, stage, and growth pattern). Aberrant localization patterns of Cx‐26 and Drg‐1 were observed in bladder tumors. There was also a significant correlation in expression among pAkt, PTEN, and L‐plastin. Although the expression of these genes correlated with factors known to be associated with patient outcome, none of them was an independent predictor of progression‐free or overall survival. © 2008 Wiley‐Liss, Inc.
Geophysical Variables and Behavior: LV. Predicting the Details of Visitor Experiences and the Personality of Experients: The Temporal Lobe Factor

The visitor experience, a more intense form of the normal sense of presence, emphasizes the deep belief of personal contact with an extraterrestrial (or religious) entity. Phenomenological details of visitor experiences are expected to reflect the functions of deep temporal lobe structures; common details involve cosmic meaningfulness, vestibular experiences, flickering, complex visual sensations and alimentary references. After intense experiences, interictal-like behaviors similar to religious conversions (widening affect, sense of personal, desire to spread the word, concern about Man's destiny) emerge. Normal people who are prone to these experiences show frequent temporal lobe signs and specific personality characteristics that include enhanced creativity, suggestibility, mild hypomania, anxiety, and emotional lability. Learning histories that encourage the use of right temporal lobe functions for the consolidation of memory, such as compartmentalization of beliefs or repression due to early sexual abuse, predispose to intense visitor experiences. The most frequent precipitants are psychological depression, personal (existential) stress and proximal exposure to the focal tectonic strain fields that accompany luminous phenomena. Possible neuropsychological mechanisms are discussed.
Time reward of value investing: evidence from the Southeast Asia stock markets

Purpose- This study tests the effectiveness of value investing and its relation to the length of investment horizon in Malaysia, Singapore, and Thailand stock markets as well as the ASEAN market as a whole. Two simple financial ratios, namely, Price-to-Earning (PE) ratio and Price-to-Book (PE) ratio, are employed to see if they represent value premium in a long-term investment. Methodology- A simulation methodology that randomly selects an investment date is applied which effectively eliminates market timing bias. Portfolios sorted by PE and PB ratios are formed on a randomly chosen date and held for different periods of time. Additionally, Fama-Mcbeth (1973) regression checks a robustness of value premium of PE and PB ratios. Findings- Portfolios constructed with low PE and PB ratio generate higher returns and form efficient portfolios with better risk-return trade-off. In a long-term investment, PE and PB are indicators of value premium. Also, the ASEAN Link provides an excellent opportunity for international diversification. Conclusion- Value investors are rewarded for holding portfolios with low PE and PB stocks for a long period of time. Furthermore, investors should construct portfolios with stocks from different markets to fully take advantage of international diversification, which significantly reduces investment risk.
Extraction Conditions of Inulin from Jerusalem Artichoke Tubers and its Effects on Blood Glucose and Lipid Profile in Diabetic Rats

This study aimed to analyze Jerusalem artichoke tubers to identify its contents and to optimize conventional extraction of inulin, various time extract, temperature, and solvent ratio were used. 30 male albino rats divided into 5 groups (6 rats) were used to evaluated the extricated inulin as Hypoglycemic agents. It could be concluded that, the highest yield of inulin was recovered from Jerusalem artichoke tuber by using the following condition, sample to solvent ratio was 1: 5 w/v at 80°C for 90 minutes. The crude inulin extracted from Jerusalem artichoke tubers were used for production of orange juice and chocolate and estimated by aid of 10 panelists. The reduction of glucose was observed after one week of feeding till the end of experimental period, also, high level of inulin 15% led to amore reduction of blood glucose level comparing with the low level especially in the end of experimental period. The crude inulin extracted from Jerusalem artichoke tubers were used in diet for diabetic rats on different levels of inulin (10 and 15%) had significantly lower in total cholesterol, triglyceride and total lipids in comparing to positive diabetic rats fed on control diet. Meanwhile, HDL level was increased significantly after fed on 10 and 15% inulin. On the other hand, LDL and VLDL levels were decreased significantly after fed on (10 and 15%) inulin in comparing to positive group rats fed on control diet.

Altered vascular reactivity induced by malaria parasites.

OBJECTIVE In this study, we have examined the possibility that there is altered vascular reactivity due to the direct interaction between parasitized erythrocytes and vascular endothelial cells. METHOD Ring preparations of rat aorta were studied using standard in vitro techniques, the rings were mounted in 20 ml organ baths containing PSS under an initial load of 1 g, maintained at 37 degrees C at pH 7.4 and isometric contractions were recorded electronically. Rings were allowed 90 minutes to equilibrate before the commencement of the various protocols: Dose responses to phenylephrine (PE) and other vasoactive agents (high-K+). Acetylcholine (Ach)--induced relaxation in phenylephrine-contracted rings (pre-contraction was induced by EC70 concentration of phenylephrine). Ach-induced relaxation in PE-precontracted, endothelium-denuded rings. Also, relaxation responses to acetylcholine was investigated through application of a single. (EC70) concentration of acetylcholine in rings exposed to blood with varying concentrations and dilutions of parasitized blood and varying durations of exposure. RESULTS Incubation with parasitized blood resulted in a significant increase in maximum contractile response to phenylephrine in the rat aortic rings (p < 0.05) but no effect to the base line. Analysis of the whole dose-response curve (using paired t-test) showed a significant left-ward shift following the addition of parasitized blood (p < 0.05), EC70 (M) values increasing from 7 x 10(-7) to 5 x 10(-6)M. Following exposure to parasitized blood, the magnitude of Ach-induced relaxation responses reduced significantly from 73 +/- 3.6 to 24.75 +/- 7.25% in rat aortic rings (p < 0.05). Ach relaxations were significantly enhanced (p < 0.05) at 5-minute exposure; however at longer durations, Ach-relaxations were variable and inconsistent. The lesser the dilution, due to increased volume of parasitized blood, the lesser the relaxation response. Following endothelium removal, there was a marked impairment in endothelium-dependent relaxation responses to ACh in both the control and incubated vessels. Exposure to parasitized blood did not significantly alter contractile responses induced by potassium depolarization. CONCLUSIONS This gives evidence in support of an endothelium-dependent action of malaria parasites as vascular effects of malaria parasites are mediated, at least in part, via endothelium-dependent mechanism(s).
Antigens in an adult T‐cell leukemia virus‐producer cell line: Reactivity with human serum antibodies

Sera from patients with adult T‐cell leukemia (ATL) or other diseases and from healthy adults, whose titers of antibodies against ATL‐associated antigens (ATLA) had been determined by indirect immunofluorescence, were analysed by a procedure of immunoprecipitation followed by SDS‐polyacrylamide gel electrophoresis. For this an ATL virus (ATLV)‐producer cell line, MT‐2, was labelled with [35S]‐methionine. All 12 anti‐ATLA‐positive sera but none of the eight anti‐ATLA‐negative sera tested reacted specifically with four polypeptides with molecular weights of 70,000, 53,000, 36,000 and 24,000 daltons. Furthermore, enrichment of three polypeptides with molecular weights of 76,000, 43,000 and 28,000 daltons was observed on reaction with anti‐ATLA‐positive sera. In control experiments using ATLA‐negative T‐cell lines, Molt‐4 and HPB‐ALL, none of these seven polypeptides were precipitated by reaction with anti‐ATLA‐positive sera. All six anti‐ATLA‐positive sera tested were shown to react with a polypeptide with a molecular weight of 24,000 of purified ATLV.
Opportunism control in exchange relationships: lessons from the French logistics industry

Over the last few years, manufacturers have progressively abandoned the management of logistical operations to entrust it to the third party logistics (3PL), most efficiently structured on the basis of global distribution networks. Working with 3PL requires implementing a suitable governance to monitor relationships and also to ensure a protection against partners’ opportunistic behaviors. A literature review is offered to determine the different strategies developed by companies to control partners’ opportunistic behaviors in exchange relationships. Formal and informal control mechanisms are reviewed to determine their usefulness in relationships. Then three case studies are conducted in the French logistics industry as this sector is at the origin of many logistical tools and innovations. The most paradoxical finding is the tolerance shown by supply chain members to a moderate level of opportunism. The importance of interpersonal relationships (social ties) – considered to reduce opportunism – is also observed and emphasizes the power of embeddedness in social networks. The three case studies point out that tolerance of a moderate level of opportunism from the partners’ part is undoubtedly a desirable option for top management. Opportunism control is expensive, it is therefore necessary to question the relevance of the application of formal or informal mechanisms of governance in exchange relationships. The original idea of a moderate level of opportunism which can be considered as acceptable represents a major novelty in supply chain management.
