Making sense of customer service experiences: a text mining review

Purpose The purpose of this paper is to systematically review the concepts and theories underlying customer service experience (CSE) and its underlying five dimensions (physical, social, cognitive, affective and sensorial). In this research, the contribution of the sensorial dimension to CSE research is emphasized. Senses are especially important in forming perceptions within servicescapes that are typically rich in sensory stimuli. Design/methodology/approach This study systematically identifies 258 articles published between 1994 and 2018 in services and marketing journals. The analysis uses a text mining approach with the Leximancer software to extract research concepts and their relationships. Findings The results demonstrate a shift from CSE research focused on brands and products toward value and interaction, around three focal areas: service system architecture, with its value creation processes; servicescape, with an increasingly digital interaction interface and outcome measures, with a stronger focus on emotional and relational metrics. In CSE research, the physical, social and cognitive dimensions are mostly researched in the focal areas of servicescape and outcome measures. Although important in practice, the sensorial dimension is the least investigated CSE dimension in service marketing research. Text mining insights demonstrate rich opportunities for sensorial research, particularly in studies on servicescape. Practical implications The synthesis will inform managers and service providers which elements of CSE are most relevant to customers when forming perceptions. These insights help service providers to control, manage and design (multi)-sensory stimuli that influence how customers will make sense of the servicescape. Originality/value This research is one of the first studies to examine the conceptual structure of CSE with a text mining approach that systematically analyzes a large set of articles, therein reducing the potential for researchers’ interpretative bias. The paper provides an assessment of the role of the largely neglected but crucial sensorial dimension, and offers future research suggestions into this emerging topic.
Pattern of Efficacy of a Musical Mnemonic on Recall of Familiar Words over Several Presentations

It has been demonstrated that musical accompaniment may aid recall of words. This study examined the mnemonic effect of music on recall of verbal material which contained no unfamiliar words over three presentations. 20 participants (average age 21.9 yr.) were randomly allocated to one of two experimental conditions and heard the to-be-remembered lyrics either being sung or read aloud without musical accompaniment. Analysis of both total number of words correctly recalled and the extent of chunking of recalled material showed better over-all recall in the song condition with evidence of greater chunking of material.
Work in progress: A prototype for identifying potential conflicts (e-Paz)

The Fund for Peace conducted an annual ranking of 178 nations based on their levels of stability and the pressure they face to maintain and improve it. Out of this number, Mozambique was ranked at 45 meaning high warning. In order to make the situation better in terms of stability and involve the citizens in peace making process we propose a prototype for e-Paz, a system utilizing Cloud Computing environment and mobile technology to be implemented for this purpose.
Gleason grade-based automatic classification of prostate cancer pathological images

In this Paper, we introduce a new method for automatic recognition and classification of prostate cancer biopsy images based on Gleason grading system. The introduced algorithm combines features from wavelet transform and fractal analysis domains. Biopsy images are pre-processed prior to features extraction using effective image processing algorithms to analyze textural complexity in terms of RGB color channels, edge and segmentation information. Experimental results achieved an average classification accuracy of 95 % in a set of 45 images with diversities in resolution, magnification levels, and stain colors.
The surgical anatomy of ulnar and median nerve communications in the palmar surface of the hand.

OBJECT Sensation in the palmar surface of the digits is supplied by the median and ulnar nerves, with the boundary classically being the midline of the ring finger. Overlap and variations of this division exist, and a communicating branch between the ulnar and median nerve could potentially explain further variations in digital sensory innervations. The aim of this study was to examine the origin and distribution of the communicating branch between the ulnar and median nerves and to apply such findings to the risk involved in surgical procedures in the hand. METHODS The authors grossly and endoscopically examined 200 formalin-fixed adult human hands obtained in 100 cadavers, and a communicating branch was found to be present in 170 hands (85%). Of the specimens with communicating branches, the authors were able to identify four notable types representing different points of connections of the branches. The most common, Type I (143 hands, 84.1%), featured a communicating branch that originated proximally from the ulnar nerve and proceeded distally to join the median nerve. Type II (12 hands, 7.1%) designated a communicating branch that originated proximally from the median nerve and proceeded distally to join the ulnar nerve. Type III (six hands, 3.5%) designated a communicating branch that traversed perpendicularly between the median and ulnar nerves in such a way that it was not possible to determine which nerve served as the point of origin. Type IV (nine hands, 5.3%) designated a mixed type in which multiple communicating branches existed, arising from both ulnar and median nerves. CONCLUSIONS According to the origin and distribution of these branching patterns, the investigators were able to define a risk area in which the communicating branch(es) may be subject to iatrogenic injury during common hand procedures.
Do Regional Price Levels Converge?: Paneleconometric Evidence Based on German Districts

We investigate price index convergence on the base of regional data for 439 German districts. Prices refer to the overall consumer price index as well as to the index without housing prices. To increase the efficiency of the testing framework, a panel unit root analysis is performed, where cross section dependencies are taken into account. The tests indicate a lack of regional price convergence. While the idiosyncratic component of price differentials is mostly stationary, their common component is driven by a unit root. The results are very similar for the overall price index and the index without housing prices, and for the Western and Eastern part of the German economy. Obviously the elimination of housing prices is not sufficient to obtain a price index where tradable products dominate. One rationale of our findings is the persistent west-east divide in consumer prices. A second argument is related to the persistence of the price gradient between urban and rural regions.
Disruption of myoglobin in mice induces multiple compensatory mechanisms.

Myoglobin may serve a variety of functions in muscular oxygen supply, such as O(2) storage, facilitated O(2) diffusion, and myoglobin-mediated oxidative phosphorylation. We studied the functional consequences of a myoglobin deficiency on cardiac function by producing myoglobin-knockout (myo(-/-)) mice. To genetically inactivate the myoglobin gene, exon 2 encoding the heme binding site was deleted in embryonic stem cells via homologous recombination. Myo(-/-) mice are viable, fertile, and without any obvious signs of functional limitations. Hemoglobin concentrations were significantly elevated in myo(-/-) mice. Cardiac function and energetics were analyzed in isolated perfused hearts under resting conditions and during beta-adrenergic stimulation with dobutamine. Myo(-/-) hearts showed no alteration in contractile parameters either under basal conditions or after maximal beta-adrenergic stimulation (200 nM dobutamine). Tissue levels of ATP, phosphocreatine ((31)P-NMR), and myocardial O(2) consumption were not altered. However, coronary flow [6.4 +/- 1.3 ml.min(-1). g(-1) [wild-type (WT)] vs. 8.5 +/- 2.4 ml.min(-1). g(-1) [myo(-/-)] [and coronary reserve [17.1 +/- 2.1 (WT) vs. 20.8 +/- 1.1 (myo(-/-) ml. min(-1). g(-1) were significantly elevated in myo(-/-) hearts. Histological examination revealed that capillary density also was increased in myo(-/-) hearts [3,111 +/- 400 mm(-2) (WT) vs. 4,140 +/- 140 mm(-2) (Myo(-/-)]. These data demonstrate that disruption of myoglobin results in the activation of multiple compensatory mechanisms that steepen the pO(2) gradient and reduce the diffusion path length for O(2) between capillary and the mitochondria; this suggests that myoglobin normally is important for the delivery of oxygen.
Relationship between muscle oxygenation and electromyography activity during sustained isometric contraction

The purpose of this study was to clarify the relationship between electromyography (EMG) spectrum changes and muscle oxygenation measured by near‐infrared time‐resolved spectroscopy (TRS). Each subject performed sustained isometric knee extension at 50% of the maximal voluntary contraction load for 1 min. Surface EMG and TRS were simultaneously recorded from the right vastus lateralis muscle. Mean power frequency (MPF) of the power spectrum was calculated every 5 s during isometric contraction using fast Fourier transform, and decrease in the slope of MPF for 1 min was calculated using the least squares method. The maximal changes in oxygenated haemoglobin and myoglobin (Oxy Hb/Mb) and in deoxygenated haemoglobin and myoglobin (Deoxy Hb/Mb) from pre‐contraction values of 1 min were calculated. There were significant relationships between the decrease in the slope of MPF and the maximal changes in Oxy Hb/Mb and Deoxy Hb/Mb (P < 0·05). These findings suggested that changes in Oxy Hb/Mb and Deoxy Hb/Mb indicate muscle fatigue assessed by EMG.
Effect of thioglycolate on phagocytic and microbicidal activities of peritoneal macrophages

Brewer thioglycolate-elicited mouse peritoneal macrophages were as active as resident peritoneal macrophages in the phagocytosis of opsonized Staphylococcus epidermidis but were unable to kill ingested microorganisms. This decreased functional activity was restricted to Brewer thioglycolate-elicited macrophages, since peritoneal macrophages elicited with NIH thioglycolate, alone or supplemented with agar and methylene blue, were as active as resident peritoneal macrophages. No effect of agar on the functional activities of macrophages was observed. A defective intracellular killing by peritoneal macrophages due to Brewer thioglycolate was seen only after an intraperitoneal injection with thioglycolate, not after in vitro incubation of resident macrophages with thioglycolate. The results of this study show that, depending on the kind of thioglycolate used, the functional characteristics of elicited macrophages may alter. However, none of the forms of thioglycolate investigated induced the recruitment of activated macrophages.
Dimension reduction of feature vectors using WPCA for robust speaker identification system

Speaker identification based on speech signal has been receiving enhanced attention from the research community. In this context the effect of dimension reduction of feature vectors using Principal Component Analysis (PCA) and Weighted Principal Component Analysis (WPCA) are compared for speaker identification in a noisy environment. MFCC feature vectors are used as original features and their dimension is reduced by PCA and WPCA techniques and then evaluated by GMM classifier. Speaker identification rate is calculated under different SNR to test the robustness of the speaker identification system. In low SNR, the speaker identification rate becomes double after reducing the dimension of feature vectors by 50% as compared to original one. The performance of WPCA is 10% to 20% better than PCA under different SNR.
Highly Efficient Genome Modifications Mediated by CRISPR/Cas9 in Drosophila

We report that Cas9/gRNA mediates efficient genetic modifications in Drosophila. Through targeting seven loci, we achieved a germline efficiency of up to 100%. Genes in both heterochromatin and euchromatin can be modified efficiently. Thus the Cas9/gRNA system is an attractive tool for rapid disruption of essentially any gene in Drosophila.
Board Gender Diversity, Earnings Quality and Stock Price Informativeness

Further recognition of women’s social value and the gradual improvement of women’s economic status have made the proportion of female independent directors on board rise year by year, which has received high attention from academia. Using data of A-share listed companies in Shanghai and Shenzhen stock markets form 2000-2014 in China, this paper investigates the relation among gender diversity, earnings quality and stock price informativeness. As a result, the larger the proportion of female independent directors is, the more firm-specific information the stock price contains. In the meantime, earnings quality of listed companies significantly impact on stock price informativeness, which means that stock prices of companies with higher earnings quality contain more firm-specific information while having other factors controlled. Further studies show that the relation between board gender diversity and stock price informativeness is not simply direct; board gender diversity could raise the stock price informativeness through enhancing earnings quality.
Internal crisis communication and employee engagement: A closer look at multinational companies

Internal crisis communication has remarkably been neglected both in research and in practice, even if there are studies that claim that internal stakeholders have a pivotal role during a crisis. This study aims to understand how multinationals use internal crisis communication and in what way they engage with their employees before, during, and after a crisis. Using the contingency theory of accommodation along with the high-reliability theory, the analysis showed that multinationals have the resources needed to develop internal crisis communication plans. How-ever, they seem to be preoccupied with fear. Furthermore, culture, both organiza-tional and national culture seem to have clear implications in the way internal cri-sis communication is practiced. (Less)
Assessing the quality of third mission activities in Portuguese universities

Since 2009, Portuguese higher education institutions have been developing their own internal quality assurance systems and policies as a result of the reforms of higher education quality assurance in Europe and Portugal. This paper analyses how far Portuguese universities, within the remit of their internal quality assurance systems, define and employ mechanisms and procedures in order to assess the quality of their third mission activities. The analysis was conducted on documents submitted by institutions to the Portuguese Agency for the Assessment and Accreditation of Higher Education (A3ES) under the institutional evaluation process. Findings suggest that although the analysed Portuguese institutions apparently embrace the third mission, the quality assurance of this core activity is still in an embryonic stage of development. This suggests that quality assurance systems need to be developed so as to integrate the various core missions of an institution (e.g. teaching and learning; research and third mission), ensuring they receive similar levels of consideration.
Structure of the TDP-epi-vancosaminyltransferase GtfA from the chloroeremomycin biosynthetic pathway

During the biosynthesis of the vancomycin-class antibiotic chloroeremomycin, TDP-epi-vancosaminyltransferase GtfA catalyzes the attachment of 4-epi-vancosamine from a TDP donor to the β-OHTyr-6 of the aglycone cosubstrate. Glycosyltransferases from this pathway are potential tools for the combinatorial design of new antibiotics that are effective against vancomycin-resistant bacterial strains. These enzymes are members of the GT-B glycosyltransferase superfamily, which share a homologous bidomain topology. We present the 2.8-Å crystal structures of GtfA complexes with vancomycin and the natural monoglycosylated peptide substrate, representing the first direct observation of acceptor substrate binding among closely related glycosyltransferases. The acceptor substrates bind to the N-terminal domain such that the aglycone substrate's reactive hydroxyl group hydrogen bonds to the side chains of Ser-10 and Asp-13, thus identifying these as residues of potential catalytic importance. As well as an open form of the enzyme, the crystal structures have revealed a closed form in which a TDP ligand is bound at a donor substrate site in the interdomain cleft, thereby illustrating not only binding interactions, but the conformational changes in the enzyme that accompany substrate binding.
Direct-to-vial experience with AutoCyte PREP in a small New England regional cytology practice.

OBJECTIVE To evaluate and assess the efficiency and efficacy of the AutoCyte PREP thin-layer Pap test method (TriPath Imaging, Inc., Burlington, North Carolina) in a privately owned cytology laboratory. STUDY DESIGN Data from 35,496 conventional Pap smear preparations performed in 1999 were compared to 6,357 conventional Pap smears and 15,534 AutoCyte PREP cases that were collected, prepared and processed from January 1 to July 31, 2000. RESULTS The AutoCyte PREP demonstrated a statistically significant increased detection of low grade squamous intraepithelial lesions (LSIL) (47%) (P = .0011) and high grade squamous intraepithelial lesions (HSIL) (116%) (P = .0002) when compared to conventional Pap smears processed during the same time period. When compared to the conventional Pap smears from 1999, the LSIL lesions increased by 57% (P < .00001), and the HSIL lesions increased by 55% (P = .0002). Both increases are statistically significant. The atypical squamous cells of undetermined significance (ASCUS)/LSIL ratio was reduced by 48% (P < .00001) using AutoCyte PREP when compared to the 1999 conventional Pap smear experience. The unsatisfactory rate was reduced by 70%. AutoCyte PREP demonstrated improved histologic correlation in HSIL cases. CONCLUSION AutoCyte PREP was significantly more effective than the conventional Pap smear for the detection of both LSIL and HSIL. The ASCUS/LSIL ratio and unsatisfactory cases were also significantly reduced.
How Differing Trade Policies May Impact U.S. Agriculture: The Potential Economic Impacts of TPP, USMCA, and NAFTA

In the last two years, the United States has reversed the post-World War II trend toward the lowering of trade barriers and a commitment towards multilateral free trade. Citing a need to “level the playing field” and hold trading partners accountable to their commitments, the current Administration has moved towards a more protectionist and perhaps mercantilist position vis-à-vis trade policy. One of the Administration’s first actions in this regard was the decision to leave the Trans-Pacific Partnership (TPP) agreement, followed thereafter by raising tariffs on steel and aluminum imports. The Administration’s actions on trade are likely to have significant implications for U.S. farmers as these actions target three of the largest markets for U.S. agricultural exports – Canada, China and Mexico – accounting for some 44%, and representing an average of $63 billion, of U.S. agricultural exports 2013 to 2015. <em>Commissioned by the <a href="https://www.farmfoundation. org/">Farm Foundation</a></em> <strong><a href="https://www.farmfoundation. org/forums/2019-farm-foundation-forums/u-s-and-canadian-perspectives-on-trans-pacific-trade/">Farm Foundation Forum</a></strong> (March 4, 2019) <ul> <li><a href="https://soundcloud.com/user-254829763/us-canadian-perspectives-on-trans-pacific-trade">Forum audio</a></li> <li><a href="https://www.farmfoundation. org/trade/">Food and Agricultural Trade Resource Center</a></li> </ul> <strong><a href="https://www.farmfoundation. org/forums/2018-farm-foundation-forums/oct-31-2018-farm-foundation-forum/">Farm Foundation Forum</a></strong> (October 31, 2018) <ul> <li><a href="https://brianallmerradionetwork.wordpress. com/2018/10/31/10-31-18-a-closer-look-at-the-purdue-universitys-global-trade-analysis-project-regarding-usmca-with-purdue-ag-economist-dominique-y-van-der-mensbrugghe-ph-d/">van der Mensbrugghe Interview</a></li> </ul>

Construct validity and reliability of a real-time multidimensional smartphone app to assess pain in children and adolescents with cancer

Abstract We evaluated the construct validity (including responsiveness), reliability, and feasibility of the Pain Squad multidimensional smartphone-based pain assessment application (app) in children and adolescents with cancer, using 2 descriptive studies with repeated measures. Participants (8-18 years) undergoing cancer treatment were drawn from 4 pediatric cancer centers. In study 1, 92 participants self-reported their level of pain twice daily for 2 weeks using the Pain Squad app to assess app construct validity and reliability. In study 2, 14 participants recorded their level of pain twice a day for 1 week before and 2 weeks after cancer-related surgery to determine app responsiveness. Participants in both studies completed multiple measures to determine the construct validity and feasibility of the Pain Squad app. Correlations between average weekly pain ratings on the Pain Squad app and recalled least, average, and worst weekly pain were moderate to high (0.43-0.68). Correlations with health-related quality of life and pain coping (measured with PedsQL Inventory 4.0, PedsQL Cancer Module, and Pain Coping Questionnaire) were −0.46 to 0.29. The app showed excellent internal consistency (&agr; = 0.96). Pain ratings changed because of surgery with large effect sizes between baseline and the first week postsurgery (>0.85) and small effect sizes between baseline and the second week postsurgery (0.13-0.32). These findings provide evidence of the construct validity, reliability, and feasibility of the Pain Squad app in children and adolescents with cancer. Use of real-time data capture approaches should be considered in future studies of childhood cancer pain.
