Fingerprint Recognition of Young Children

In 1899, Galton first captured ink-on-paper fingerprints of a single child from birth until the age of 4.5 years, manually compared the prints, and concluded that “the print of a child at the age of 2.5 years would serve to identify him ever after. ” Since then, ink-on-paper fingerprinting and manual comparison methods have been superseded by digital capture and automatic fingerprint comparison techniques, but only a few feasibility studies on child fingerprint recognition have been conducted. Here, we present the first systematic and rigorous longitudinal study that addresses the following questions: 1) Do fingerprints of young children possess the salient features required to uniquely recognize a child? 2) If so, at what age can a child’s fingerprints be captured with sufficient fidelity for recognition? 3) Can a child’s fingerprints be used to reliably recognize the child as he ages? For this paper, we collected fingerprints of 309 children (0–5 years old) four different times over a one year period. We show, for the first time, that fingerprints acquired from a child as young as 6-h old exhibit distinguishing features necessary for recognition, and that state-of-the-art fingerprint technology achieves high recognition accuracy (98.9% true accept rate at 0.1% false accept rate) for children older than six months. In addition, we use mixed-effects statistical models to study the persistence of child fingerprint recognition accuracy and show that the recognition accuracy is not significantly affected over the one year time lapse in our data. Given rapidly growing requirements to recognize children for vaccination tracking, delivery of supplementary food, and national identification documents, this paper demonstrates that fingerprint recognition of young children (six months and older) is a viable solution based on available capture and recognition technology.
Subcultural ostensive luxury as a creative and mimetic process: The case of the Sapeurs Parisiens

Luxury brands use an authoritarian discourse. It governs the ostentatious and conformist consumption that lays down social distances. Some subcultures are adopting luxury brands for ostensive practices that blur social distinctions. Such consumption can be problematic for luxury brands, which lose control over their discourse and have to satisfy both their traditional clients and this new clientele. The purpose of this research is to understand the practices, processes and individual and collective effects of subcultural ostensive use of luxury brands and the mimetic mechanisms found therein. An empirical study was carried out on the Sapeurs Parisiens, a subculture of African dandies. An interpretive analysis was carried out on interviews as well as photographic, videographic and netnographic observations. This enables us to understand this subculture as an individuating practice involving luxury items which takes place through a process of hybridisation and creates a specific grotesque genre. This research contributes to the distinction between ostentatious and ostensive luxury and a better understanding of creative mimetic processes. Ostensive luxury is an interesting source of co-creativity and raises questions about the risks facing brands.

A distributed approach for the optimal power flow problem

For operating electrical power networks, the Optimal Power Flow (OPF) problem plays a central role. The problem is nonconvex and NP hard. Therefore, designing efficient solution algorithms is crucial, though their global optimality is not guaranteed. Existing semi-definite programming relaxation based approaches are restricted to OPF problems for which zero duality holds, whereas for non-convex problems there is a lack of solution methods of provable performance. In this paper, an efficient novel method to address the general nonconvex OPF problem is investigated. The proposed method is based on alternating direction method of multipliers combined with sequential convex approximations. The global OPF problem is decomposed into smaller problems associated to each bus of the network, the solutions of which are coordinated via a light communication protocol. Therefore, the proposed method is highly scalable. The convergence properties of the proposed algorithm are mathematically and numerically substantiated.
Constructing Organizational Identity on Internal Social Media

This study explored how coworkers use internal social media (ISM) to contribute to the construction of organizational identity. The study analyzed 3 months of interactions among coworkers at a large Danish bank on ISM. In addition, 17 coworkers were interviewed to provide additional understanding about the online interactions. The study found that these coworkers constructed organizational identity when they challenge, negotiate, and discuss organizational issues on ISM. They use phrases from vision and mission statements to support their arguments and to push the understanding of organizational identity so that it is in line with their perceptions of what the bank really is or should be. Some of these discussions on ISM develop into organizational stories, which are shared and discussed in informal, in-person conversations among coworkers. The stories become narratives, which contribute to the organizational identity, help coworkers make sense of the organization, and help them identify with the organization.
Cilia, flagella, and microtubules

In 1676 Leeuwenhoek sent to the Royal Society of London a letter describing his discovery of protozoa and their cilia and flagella . He wrote, "I also discovered a second sort of animalcules, whose figure was an oval, . provided with diverse incredibly thin little feet, or little legs [cilia], which were moved very nimbly . , and wherewith they brought off incredibly quick motions" (cf. translation of letter 18 [1]) . Cilia and flagella were observed on a variety of cells during the next two hundred years, and by the end of the 19th century several theories had been proposed to explain flagellar beating . For example, it was postulated that flagella were lifeless and were moved by elements within the cell body or were hollow structures into which fluid was injected and withdrawn . Alternatively, it was suggested that flagella contained a central contracting fiber or possessed a fibrillar substructure . This last theory had been formulated in 1868 by Engelmann, who proposed that the flagellum contained aligned fibrillar elements which shortened into a globular form during beating . Although Jensen in 1887 and Ballowitz in 1888 observed numerous fibrils in the fraying tips of sperm tails, the prevailing belief at the turn of the century was that the flagellum contained a solid contracting core (see reference 2) . In later studies, the fibrillar substructure of cilia and flagella was described in a variety ofcells (2, 3), and these observations were confirmed with the development of the electron microscope (4-7) . The number of fibrils was variously reported as between nine and twelve, and the diversity of ciliary and flagellar wave forms suggested no reason that the number of fibrils would be constant among species .
Inhibition of Lateral Prefrontal Cortex Produces Emotionally Biased First Impressions: A Transcranial Magnetic Stimulation and Electroencephalography Study

Optimal functioning in everyday life requires the ability to override reflexive emotional responses and prevent affective spillover to situations or people unrelated to the source of emotion. In the current study, we investigated whether the lateral prefrontal cortex (lPFC) causally regulates the influence of emotional information on subsequent judgments. We disrupted left lPFC function using transcranial magnetic stimulation (TMS) and recorded electroencephalography (EEG) before and after. Subjects evaluated the likeability of novel neutral faces after a brief exposure to a happy or fearful face. We found that lPFC inhibition biased evaluations of novel faces according to the previously processed emotional expression. Greater frontal EEG alpha power, reflecting increased inhibition by TMS, predicted increased behavioral bias. TMS-induced affective misattribution was long-lasting: Emotionally biased first impressions formed during lPFC inhibition were still detectable outside of the laboratory 3 days later. These findings indicate that lPFC serves an important emotion-regulation function by preventing incidental emotional encoding from automatically biasing subsequent appraisals.
Pharmacokinetics and body distribution of amiodarone in man.

The concentrations of amiodarone (Cordarone) and desethylamiodarone in plasma after single oral and intravenous and long-term oral dosing were determined in seven normal subjects and 106 patients with various cardiac arrhythmias, respectively, using a high-performance liquid chromatographic method. The decline in amiodarone plasma concentration after a single intravenous 400 mg dose was described by a triexponential decay equation, with a mean terminal half-life (t1/2) of 34.5 h. Model independent parameters were calculated from the fits. Mean values for clearance and apparent volume of distribution were 14.7 +/- 7.2 l/h and 376 +/- 372 l. Following single oral doses of 400 mg, amiodarone plasma concentration time data were fitted in a triexponential function. The mean terminal half-life for amiodarone after oral dosage was 31.6 +/- 21.3 h. Amiodarone peak concentrations of 0.37 +/- 0.22 micrograms/ml were attained in 4.8 +/- 1.5 h. The bioavailability of oral amiodarone was only 31 +/- 26%, in part due to first-pass metabolism. Desethylamiodarone , the major metabolite of amiodarone, was present in plasma in very low levels of about 10 ng/ml in several volunteers after single intravenous or oral administration of amiodarone. The mean plasma amiodarone and desethylamiodarone levels in 106 patients, using a mean oral daily maintenance dosage of 440 +/- 253 mg for a mean period of 9.1 months, were 1.85 +/- 1.17 micrograms/ml and 1.35 +/- 0.71 micrograms/ml, respectively. The relationship between the steady state amiodarone and desethylamiodarone plasma concentrations and daily amiodarone maintenance dose in mg in 106 patients was investigated.

Changing the Firm's Digital Backbone: How Information Technology shapes the Boundaries of the Firm

How does Information and Communication Technology (IT) influence boundaries within and across organizations? Most of the research to date has considered the impact of technologies linking buyers and suppliers, focusing on interorganizational technology such as electronic markets. Our paper takes a different view, focusing on a firm’s overall boundaries, as opposed to individual make-orbuy decisions that an electronic market would manage. Drawing on a large apparel manufacturer’s vertical redesign, we show that different types of IT play different roles in boundary design. We find that “mediating” technologies that link two parties (e.g. Electronic Data Interchange or e-markets) are not as critical as “architectural” technologies (e.g. Enterprise Resource Planning systems) in shaping firm boundaries. We consider how IT, and in particular architectural IT, helps create easily re-configurable “vertical packages”, i.e. configurations of business processes that fulfill a distinct business need. We find that IT facilitates the optimization of an organization’s resources and capabilities and thus increases a firm’s flexibility. We also predict that recent developments in Enterprise Resource Planning (ERP) systems will have substantial impact on organizational design.
The detection of porcine circovirus 3 in Guangxi, China

Porcine circovirus type 3 (PCV3) is a novel circovirus that was firstly detected in the USA. PCV3 is associated with porcine dermatitis and nephropathy syndrome (PDNS), reproductive failure and cardiac and multisystemic inflammation. Latterly, PCV3 was detected in Guangxi, China. Forty-one of 108 (37.96%) samples and nine of 47 (19.14%) samples were PCV3 positive in pig farms and pig slaughter houses, respectively. Three PCV3 strains were sequenced and designated PCV3-China/GX2016-1, PCV3-China/GX2016-2 and PCV3-China/GX2016-3. The complete genome of PCV3-China/GX2016-2 and PCV3-China/GX2016-3 is both 2,000 bp in length, while PCV3-China/GX2016-1 is of 1,999 bp and has a G deletion at position of 1,155 in its genome. The complete genome and capsid nucleotide of the three PCV3 strains identified in this study shared 97.5%-99.4% and 96.7%-99.1% identities with that of the other PCV3 strains available in NCBI, respectively. Phylogenetic analysis based on complete genome and capsid gene of 35 PCV3 strains showed that the three PCV3 sequences from Guangxi Province were divided into two clusters. The results of this study contribute to the understanding of PCV3 molecular epidemiology.
A Quantitative Comparison of Calibration Methods for RGB-D Sensors Using Different Technologies

RGB-D (Red Green Blue and Depth) sensors are devices that can provide color and depth information from a scene at the same time. Recently, they have been widely used in many solutions due to their commercial growth from the entertainment market to many diverse areas (e.g., robotics, CAD, etc.). In the research community, these devices have had good uptake due to their acceptable level of accuracy for many applications and their low cost, but in some cases, they work at the limit of their sensitivity, near to the minimum feature size that can be perceived. For this reason, calibration processes are critical in order to increase their accuracy and enable them to meet the requirements of such kinds of applications. To the best of our knowledge, there is not a comparative study of calibration algorithms evaluating its results in multiple RGB-D sensors. Specifically, in this paper, a comparison of the three most used calibration methods have been applied to three different RGB-D sensors based on structured light and time-of-flight. The comparison of methods has been carried out by a set of experiments to evaluate the accuracy of depth measurements. Additionally, an object reconstruction application has been used as example of an application for which the sensor works at the limit of its sensitivity. The obtained results of reconstruction have been evaluated through visual inspection and quantitative measurements.
Cross-Validation Assessment of Alternatives to Individual-Level Conjoint Analysis: A Case Study

Recently, both Hagerty and Kamakura have proposed insightful suggestions for improving the predictive accuracy of conjoint analysis via various types of averaging of individual responses. Hagerty uses Q-type factor analysis (i.e., optimal weighting) and Kamakura a hierarchical cluster analysis that optimizes predictive validity. Both approaches are compared with conventional conjoint and self-explicated utility models using real datasets. Neither the Hagerty nor the Kamakura suggestions lead to higher predictive validities than are obtained by conventional conjoint analysis applied to individual response data.
SURVEY THE RELATIONSHIP BETWEEN JOB SATISFACTION AND WORKPLACE SPIRITUALITY

Nowadays, the importance of employee organization is perceived, it is also very important to be considered as one of the most important sources of satisfaction. Therefore, many researchers have focused on the analysis of job satisfaction and other work environment as one of the factors that may play role in job satisfaction. The aim of this study was to determine the relationship between workplace spirituality and job satisfaction of employees in government agencies is Jiroft. This Study is a descriptive and correlational research that has been conducted through a survey. The study sample included all of the government agencies in Jiroft in 1390 and random samples of 322 subjects were selected. In order to analyze the data, descriptive and inferential statistics were used. For workplace spirituality mailman’s standard questionnaire were used and for Job satisfaction we used Researcher made questionnaire. Findings suggest that the variables in the sense of working relationships with others, and alignment with organizational values and job satisfaction relationship has been reported.
Proteotypic profiling of LHCI from Chlamydomonas reinhardtii provides new insights into structure and function of the complex

We used isotope dilution MS to measure the stoichiometry of light‐harvesting complex I (LHCI) proteins with the photosystem I (PSI) core complex in the green alga Chlamydomonas reinhardtii. Proteotypic peptides served as quantitative markers for each of the nine gene products (Lhca1–9) and for PSI subunits. The quantitative data revealed that the LHCI antenna of C. reinhardtii contains about 7.5 ± 1.4 subunits. It further demonstrated that the thylakoid LHCI population is heterogeneously composed and that several lhca gene products are not present in 1:1 stoichiometries with PSI. When compared with vascular plants, LHCI of C. reinhardtii possesses a lower proportion of proteins potentially contributing to far‐red fluorescence emission. In general, the strategy presented is universally applicable for exploring subunit stoichiometries within the C. reinhardtii proteome.
Isolation and Phylogenetic Analysis of Novel Viruses Infecting the Phytoplankton Phaeocystis globosa (Prymnesiophyceae)

ABSTRACT Viruses infecting the harmful bloom-causing alga Phaeocystis globosa (Prymnesiophyceae) were readily isolated from Dutch coastal waters (southern North Sea) in 2000 and 2001. Our data show a large increase in the abundance of putative P. globosa viruses during blooms of P. globosa, suggesting that viruses are an important source of mortality for this alga. In order to examine genetic relatedness among viruses infecting P. globosa and other phytoplankton, DNA polymerase gene (pol) fragments were amplified and the inferred amino acid sequences were phylogenetically analyzed. The results demonstrated that viruses infecting P. globosa formed a closely related monophyletic group within the family Phycodnaviridae, with at least 96.9% similarity to each other. The sequences grouped most closely with others from viruses that infect the prymnesiophyte algae Chrysochromulina brevifilum and Chrysochromulina strobilus. Whether the P. globosa viruses belong to the genus Prymnesiovirus or form a separate group needs further study. Our data suggest that, like their phytoplankton hosts, the Chrysochromulina and Phaeocystis viruses share a common ancestor and that these prymnesioviruses and their algal host have coevolved.
For fun and profit: Hedonic value from image interactivity and responses toward an online store

With the use of an on-line retailer's Web site and an experimental method with 103 university students, statistical support through path analysis was found for positive influences of optimum stimulation level (preferred level of environmental stimulation) and recreational shopping on hedonic value (trying an image-interactivity feature of an apparel Web site as a stimulating experience). The Web site's mixandmatch image interactivity feature allowed creation of visual images of product combinations. The path-analysis model revealed significant paths between hedonic value and resulting emotional pleasure and arousal variables. A pattern of significant paths was also found between these three variables and global attitude, willingness to purchase, and willingness to patronize the on-line store. Theoretical and managerial conclusions are provided. © 2005 Wiley Periodicals, Inc.
Walker 256 tumor‐bearing rats demonstrate altered interstitial cells of Cajal. Effects on ICC in the Walker 256 tumor model

Cachexia is a significant problem in patients with cancer. The effect of cancer on interstitial cells of Cajal (ICC) and neurons of the gastrointestinal tract have not been studied previously. Although supplementation with L‐glutamine 2% may have beneficial effects in cancer‐related cachexia, and be protective of ICC in models of oxidative stress such as diabetes, its effects on ICC in cancer have also not been studied.
RAB43 facilitates cross-presentation of cell-associated antigens by CD8α+ dendritic cells

RAB43 is a vesicular transport protein unique to CD8α+ DCs that is localized to the Golgi. Kretzer et al. show that RAB43 is necessary for optimal cross-presentation of cell-associated antigens by CD8α+ DCs in vitro and in vivo but that it is dispensable for cross-presentation by in vitro monocyte-derived DCs.
Systemic Absorption and Effects of Nicotine From Smokeless Tobacco

Nicotine is absorbed in substantial quantities from smokeless tobacco and could contribute to the adverse consequences of smokeless tobacco use. Chronic systemic exposure to nicotine could contribute to accelerated coronary artery disease, acute cardiac ischemic events, and hypertension. Systemic absorption of sodium and mutagenic chemicals from smokeless tobacco could aggravate hypertension or cardiac failure, or contribute to cancer, respectively. Information concerning the potential hazards of nicotine and other systemically absorbed toxins may be incorporated into educational programs to discourage the use of smokeless tobacco.
Using the Objective Borderline Method (OBM) to support Board of Examiners’ decisions in a medical programme

Abstract Decisions about progress through an academic programme are made by Boards of Examiners, on the basis of students’ course assessments. For most students such pass/fail grading decisions are straightforward. However, for those students whose results are borderline (either at a pass/fail boundary or boundaries between grades) the exercise of some discretion by university staff is required. In the interests of the transparency of the exercise of this discretion and to increase the chances that the ‘right’ decision is made, we tested the validity of the second version of the Objective Borderline Method (OBM2) decision-making tool in a medical programme. Our results suggest that application of OBM2 provides valid data to help university staff make robust decisions about a student’s progression through a programme, and with which to defend these decisions if that should be required.
