THE ANTECEDENTS OF PROCRASTINATION BEHAVIOR: PERSONALITY CHARACTERISTICS, SELF ESTEEM AND SELF EFFICACY

This study aims to investigate some antecedents of procrastination behaviors of employees. Within the literature, studies suggest that some individual factors lead employees to procrastinate their jobs at another time. Therefore, big five personality characteristics, selfesteem and self efficacy are considered as predictors of procrastination behaviors within the scope of the study. For this purpose, the data which were collected from 300 employees from hospitals by the survey method were analyzed using the structural equation modelling. The results of the study indicate that two personality characteristics of big five which are addressed as conscientiousness and neuroticism have a significant effect on procrastination behaviors of employees. In other words, while employees' conscientiousness level has a negative effect on procrastination behavior; neuroticism level has a positive effect on procrastination behavior. However, extraversion and agreeableness have no significant effect on procrastination behavior. In addition, employees' self esteem levels have a positive and significant effect on procrastination behavior; whereas self efficacy beliefs have negative and significant effect on procrastination behavior
The Chicken Egg Dilemma: Legionnaires' Disease and Retrograde Contamination of Dental Unit Waterlines
Venue: Infection Control #x0026; Hospital Epidemiology

the Centers for Disease Control and Prevention/ National Healthcare Safety Network, are primarily designed for surveillance purposes, and only patients with KPC 2 Kp bacteriuria who do not meet these criteria are thought to have urinary tract infection and receive treatment. The results presented here show that the outcomes of CRE bacteriuria/bacteremia are influenced by both the choice of antimicrobial treatment and the CRE isolate type. The selective pressure imposed by antibiotic usage has been strongly associated with the emergence of resistance, as observed in this study and in previous reports regarding polymyxins, tigecycline, and fosfomycin, which are considered "reappraised" therapeutic options to treat multidrug resistant microorganisms. Unequivocally, endemic KPC 2 Kp has become quite more competitive than multidrug resistant noncarbapenemase isolates that proved to be self limited, with neither bacteremia case nor development of resistance observed in this study (Table 1) KPC 2 Kp is probably favored by the presence of a more robust resistance mechanism, such as the production of carbapenemase, although blaKPC 2 gene has not been associated with virulence by itself. In conclusion, KPC 2 Kp isolates presented with recurrent/ subsequent bacteriuria as the main urinary outcome and as such developed cases of bacteremia with a high 30 day mortality rate being observed. Increase in resistance rates was observed for all agents evaluated, possibly driven by previous use similar to prior observations for KPC 2 Kp recovered from surveillance rectal swab samples. These findings and the poor outcomes for KPC 2 Kp infection underscore the urgent need for better surveillance and stewardship programs to combat these antibiotic stains.
Protocol independent identification of encrypted video traffic sources using traffic analysis
Venue: 2016 IEEE International Conference on Communications (ICC)

This paper presents a mechanism to use Traffic Analysis (TA) for identifying sources of tunneled video streaming traffic. The key idea is to probe encrypted and tunneled video streaming traffic at a client side firewall so that the firewall can identify the traffic source using traffic analysis, and block or throttle traffic from that particular source. The key contribution in this paper is to evaluate Packet Arrival Interval (PAI) as a classification feature for identifying sources of tunneled video streaming traffic. Using OpenVPN servers for creating encryption tunnels, experiments are conducted for a large number of popular video steaming servers and multiple client devices located in different geographical locations. It was experimentally demonstrated that using PAI as a classification feature it is indeed possible to identify video streaming sources with high accuracy and low false positive rates. The paper also does a thorough analysis of PAI to reveal that the feature embeds two very important classification sub features, namely, Inter Packet Delay Variation (IPDV) and Inter Packet Generation Delay (IPGD) Classification is then performed using those two sub features to demonstrate their abilities for video source identification.
PT LDA: A latent variable model to predict personality traits of social network users
Venue: Neurocomputing

Online social network presents a great opportunity to analyze user behavior and mine the implicit personality traits from the social network data. Considering the personality recognition as a multi label classification problem, this paper proposes a new probabilistic topic model (PT LDA model) to predict the personality traits within the framework of Five Factor Model. The proposed model extends the Latent Dirichlet Allocation (LDA) model to integrate the n gram features into few latent topics and each topic is characterized by not only the multinomial distribution over words but also the Gaussian distributions over personality traits. This paper develops a Gibbs EM algorithm to solve the proposed model iteratively based on Gibbs sampling and expectation maximization. Quantitative evaluation shows that PT LDA is more accurate, efficient and robust than several baselines. Our experiment also shows that the proposed model can be used to extract the interpretable topics associated with each personality trait, which provides a new way to uncover user behaviors in online social network.
Personality Trait Development During the Transition to Parenthood

Social investment theory (SIT) proposes that the transition to parenthood triggers positive personality trait change in early adulthood. Using data from a representative sample of first time parents compared to nonparents, the results of rigorous tests do not support the propositions of SIT. Specifically, we found no evidence for the proposition that parents show more pronounced mean level increases in emotional stability, agreeableness, and conscientiousness compared to nonparents. We did find that agreeableness and openness changed depending on how long someone was in the parent role. Finally, our results suggest that high extraversion and low openness in both genders and high conscientiousness in females predict the likelihood to enter into parenthood. Discussion focuses on why this transition seems to be unrelated to mean level personality trait change and the implications of these results for SIT.
MIIP remodels Rac1 mediated cytoskeleton structure in suppression of endometrial cancer metastasis
Venue: Journal of Hematology Oncology

BackgroundEndometrial carcinoma (EC) is one of the most common malignancies of the female reproductive system. Migration and invasion inhibitory protein (MIIP) gene was recently discovered candidate tumor suppress gene which located at chromosome 1p36.22. 1p36 deletion was found in many types of tumor including EC. In the present study, we will determine the role and mechanism of MIIP in EC metastasis.MethodsImmunohistochemistry was used to measure MIIP expression in normal and EC tissue. Both gain of function (infection) and loss of function (siRNA) assays were used to alter MIIP expression levels. The effect of MIIP on cell migration and invasion was measured by transwell assay. F actin immunofluorescence staining was used to observe the cell morphology. The activation of GTP loaded Rac1 was evaluated by Rac activity assay kit. Immunoprecipitation/WB was used to measure the interaction between MIIP and PAK1.ResultsWe demonstrate that MIIP expression was significantly decreased in EC patients comparing to the normal ones, and decreased MIIP expression in EC tissues is associated with deep myometrial invasion, advanced stage, and the presence of lymph node metastasis. Using both gain of function (infection) and loss of function (siRNA) assays, we show that MIIP markedly blocked EC cell migration, whereas loss of MIIP led to increase in EC cell migration. We demonstrate that elevated expression of MIIP resulted in cytoskeleton reorganization with decreased formation of lamellipodia. We also provide evidence that MIIP is a key molecule in directing Rac1 signaling cascades in EC. Ectopically expressed MIIP consistently competed with Rac1 GTP for binding with the PAK1 p21 binding domain. Our data show that MIIP and PAK1 bind each other and that a C terminal polyproline domain of MIIP is required for PAK1 binding. Deletion of the PAK1 binding domain of MIIP reduced cell migration inhibiting activity.ConclusionsMIIP may function as a tumor suppressor gene for endometrial carcinoma. MIIP attenuates Rac1 signaling through a protein interaction network, and loss of this regulator may contribute to EC metastasis.
Parasitic leiomyomas: a systematic review.
Venue: European journal of obstetrics, gynecology, and reproductive biology

Parasitic leiomyomas were first described as early as 1909 but are a rare condition. In recent years, due to the rise of laparoscopic surgery and power morcellation, several cases of parasitic leiomyomas associated with this surgical procedure have been reported.  A literature search was performed using PubMed, Embase and Google Scholar with the following combination of keywords: leiomyoma OR uterine neoplasms OR uterine myomectomy OR laparoscopy OR hysterectomy OR peritoneal neoplasms AND parasitic. Papers describing parasitic leiomyomas were included. The results of these studies are summarized herein.  We retrieved abstracts of 756 papers. Of these, 591 were excluded for not fulfilling the inclusion criteria and 54 were removed as duplicates; after full text assessment, 8 were rejected for presenting cases of malignancy and finally 103 were included in our systematic review. From these, we present information about 274 patients with parasitic leiomyomas. The mean age of women was 40 years (range 18 79 years) and 154 (56% had no history of uterine surgery, the others (120, 44% having had a previous myomectomy or hysterectomy. Of the total, 106 (39% women had a history of power morcellation. The most frequent clinical symptom was abdominal pain (49% and the most frequent presentation was disseminated peritoneal leiomyomatosis.  While parasitic leiomyoma was first described a century ago, the recent introduction of laparoscopic power morcellation has increased the number of reported cases.
A rare case of primary parasitic leiomyoma mimicking as ovarian mass: a clinical dilemma

Uterine leiomyomas are the most common benign pelvic tumors in women of reproductive age group. Parasitic or wandering leiomyomas are known for their rarity, atypical clinical presentation unusual location, posing challenge in making radiological and clinical diagnosis. More recently, rise in incidence of secondary parasitic leiomyomas has been reported as a complication of laparoscopic myomectomy and morcellations. We report an interesting case of primary parasitic leiomyoma which initially seemed to be a case of ovarian tumor. A 38 year old woman presented with chief complaints of pain in lower abdomen since 4 months with abdominal swelling since 2 months with CT abdomen suggestive of 8.7x5.2 cm exophytic right ovarian neoplasm with differential diagnosis of broad ligament fibroid in pouch of douglas. She had no previous history of abdominal or laparoscopic myomectomy and no family history of genital tract and breast malignancy. On clinical examination, no mass could be palpated per abdominally but a firm mass of 8 x6 cm size was felt through posterior fornix. Intraoperatively, a solid mass with lobulated surface was noted in pouch of Douglas attached through a thin vascular pedicle to sigmoid colon. Differential diagnosis considering location of tumor and pathological examination included possibility of gastrointestinal stromal tumor or extra gastrointestinal stromal tumor or wandering leiomyoma. However, on histopathological slide examination (using immunohistochemistry) GIST was ruled out and diagnosis of parasitic fibroid was confirmed. Therefore, while dealing with pelvic tumors with atypical clinical presentation, possibility of these rare tumors have to be kept in mind for appropriate management.
Spontaneous parasitic leiomyoma in a post partum woman
Venue: The journal of obstetrics and gynaecology research

We report a case of spontaneous parasitic leiomyoma in a 30 year old post partum woman. A subserosal leiomyoma had been noted at the first trimester screening, and she had experienced persistent abdominal pain during her previous pregnancy. She was referred to hospital with severe abdominal pain at 7 months after delivery. We detected a homogenous solid tumor that resembled the subserosal leiomyoma but was completely detached from the uterus. On laparoscopy the vascularization of the tumor was supplied from the omentum, which was tightly adherent to the tumor. Histopathologically, the tumor was surrounded by a fibrous vascular capsule, and broadly hyalinized and partially calcified, consistent with a degenerated uterine leiomyoma. Detachment of a pedunculated subserosal leiomyoma from the uterus following adhesion to other pelvic structures throughout pregnancy may result in a parasitic leiomyoma, a rare subtype of uterine leiomyoma.
Torsion of a parasitic myoma that developed after abdominal myomectomy
Venue: Obstetrics gynecology science

Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38 year old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exploratory laparotomy. A parasitic mass 17 cm in diameter with a twisted omental pedicle was identified. En bloc excision of the mass and omentum was performed, followed by total abdominal hysterectomy. Histopathological examination of multiple sections revealed features compatible with an infarcted leiomyoma. Thus, we present a very rare case of an iatrogenic, rapidly growing parasitic myoma complicated by omental torsion (which caused the acute abdominal pain) We also offer a literature review.
Mechanical Properties and Fatigue Behavior of Unitized Composite Airframe Structures at Elevated Temperature

The tension tension fatigue behavior of a newly developed unitized composite material system was investigated. The unitized composite consisted of a polymer matrix composite (PMC) co cured with a ceramic matrix composite (CMC) The PMC portion consisted of an NRPE high temperature polyimide matrix reinforced with carbon fibers woven in an eight harness satin weave (8HSW) The CMC layer is a single ply non crimp 3D orthogonal weave composite consisting of ceramic matrix reinforced with glass fibers. In order to assess the performance and suitability of this composite for use in aerospace components designed to contain high temperature environments, mechanical tests were performed under temperature conditions simulating the actual operating conditions. In all elevated temperature tests the CMC side of the test specimen was at 329 deg C while the PMC side was exposed to ambient laboratory air. The tensile properties were measured at elevated temperature for both on axis [0/90] and off axis 45] fiber orientations. Tension tension fatigue tests were conducted at elevated temperature at a frequency of 1.0 Hz with a ratio of minimum stress to maximum stress of R= 0.05.
A Big Five facet analysis of a psychopath: The validity of the HDS mischievous scale of sub clinical psychopathy.
Venue: Scandinavian journal of psychology

Around 5,700 British adults completed the NEO PI R, which measures the Big Five Personality factors at the Domain and the Facet level, as well as the Hogan Development Survey (HDS) measure of Anti Social Personality Disorder called Mischievous. Previous work in this field has used clinical measures of psychopathy and either student or patient samples. This sought to validate this measure by comparing NEO facet correlational results with other studies. The Mischievous score from the HDS was the criterion variable in the correlations and multiple regressions. Mischievous people were Disagreeable, Stable, Extraverts, lacking in Conscientiousness. Facet analysis showed them high on Excitement seeking but low of Straightforwardness, Anxiety and Deliberation. Limitations are of the study are discussed.
Factors affecting the content of the ursolic and oleanolic acid in apple peel: influence of cultivars, sun exposure, storage conditions, bruising and Penicillium expansum infection.
Venue: Journal of the science of food and agriculture

For health promotion and as part of natural plant protection, it might be of interest to increase the content of oleanolic acid (OA) and ursolic acid (UA) by biofortification in breeding programs, although the extent of the influence of genetic and environmental factors needs to be clarified. The objective of this study was to determine the effect of cultivar, sun exposure, storage, bruising and fungal infection on the OA and UA content in apple peel.  Three apple cultivars with different ripening times 'Discovery' (early) 'Aroma' (middle) and 'Gloster' (late) were investigated. The content of OA and UA was mainly influenced by cultivar and side subjected to sun exposure, and to a minor extent by storage and seasonal year. 'Gloster' had the highest OA and UA content of the investigated cultivars. OA and UA content on the shaded side was higher than that on the sun exposed side in all three cultivars. Inoculation with Penicillium expansum did not have any consistent effect on OA or UA, except in a few cases where the levels decreased.  OA and UA content can be increased by choice of cultivar in the breeding process and to some extent by cultural practice.
Multiple Arousal Theory and Daily Life Electrodermal Activity Asymmetry

Using "big data" from sensors worn continuously outside the lab, researchers have observed patterns of objective physiology that challenge some of the long standing theoretical concepts of emotion and its measurement. One challenge is that emotional arousal, when measured as sympathetic nervous system activation through electrodermal activity, can sometimes differ significantly across the two halves of the upper body. We show that traditional measures on only one side may lead to misjudgment of arousal. This article presents daily life and controlled study data, as well as existing evidence from neuroscience, supporting the influence of multiple emotional substrates in the brain causing innervation on different sides of the body. We describe how a theory of multiple arousals explains the asymmetric EDA findings.
Developments in Trait Emotional Intelligence Research

Trait emotional intelligence "trait EI" concerns our perceptions of our emotional abilities, that is, how good we believe we are in terms of understanding, regulating, and expressing emotions in order to adapt to our environment and maintain well being. In this article, we present succinct summaries of selected findings from research on (a) the location of trait EI in personality factor space, (b) the biological underpinnings of the construct, (c) indicative applications in the areas of clinical, health, social, educational, organizational, and developmental psychology, and (d) trait EI training. Findings to date suggest that individual differences in trait EI are a consistent predictor of human behavior across the life span.
NOAA QC Tools Origin Development and Future

Advancing multibeam technology allows us to map the seafloor better than ever before, and we have plenty of stunning bathymetry to show for it. Yet the ever increasing data volume presents some challenges during both quality review and in its generalization to nautical chart scale. Specific challenges and inefficiencies in these processes are addressed with NOAA QC tools, specifically: 1) "flier finder" which scans gridded bathymetry and flags anomalous data "fliers" for easy identification and removal, 2) feature scans, to ensure proper attribution and accurate representation within gridded bathymetry, and 3) an automated method of comparing survey soundings to those charted, as a formal means of chart comparison, identification of dangers to navigation, and also in the evaluation of a prospective chart sounding selection. This paper discusses the QC tools listed above, with regards to: 1) their organic development within NOAA, to alleviate redundant, manually intensive tasks better suited for automation, 2) their implementation into the Rapid Survey Assessment (RSA) process of the NOAA Hydrographic Surveys Division (HSD) 3) their joint development with the Center for Coastal and Ocean Mapping Joint Hydrographic Center (CCOM/JHC) through their integration within the HydrOffice research framework, and 4) future and ongoing improvements. Proposed innovation includes flier identification through a multi detector algorithm, a "smart" chart sounding selection, and a wide range of task specific applications to facilitate all phases of ocean mapping.
A novel queue management policy for delay tolerant networks
Venue: EURASIP J. Wirel. Commun. Netw.

Delay tolerant networks (DTNs) have attracted increasing attention from governments, academia and industries in recent years. They are designed to provide a communication channel that exploits the inherent mobility of trams, buses and cars. However, the resulting highly dynamic network suffers from frequent disconnections, thereby making node to node communications extremely challenging. Researchers have thus proposed many routing/forwarding strategies in order to achieve high delivery ratios and/or low latencies and/or low overheads. Their main idea is to have nodes store and carry information bundles until a forwarding opportunity arises. This, however, creates the following problems. Nodes may have short contacts and/or insufficient buffer space. Consequently, nodes need to determine (i) the delivery order of bundles at each forwarding opportunity and (ii) the bundles that should be dropped when their buffer is full. To this end, we propose an efficient scheduling and drop policy for use under quota based protocols. In particular, we make use of the encounter rate of nodes and context information such as time to live, number of available replicas and maximum number of forwarded bundle replicas to derive a bundle's priority. Simulation results, over a service quality metric comprising of delivery, delay and overhead, show that the proposed policy achieves up to 80 improvement when nodes have an infinite buffer and up to 35 when nodes have a finite buffer over six popular queuing policies: Drop Oldest (DO) Last Input First Output (LIFO) First Input First Output (FIFO) Most FOrwarded first (MOFO) LEast PRobable first (LEPR) and drop bundles with the greatest hop count (HOP COUNT)
