Social Media Image Retrieval Using Distilled Convolutional Neural Network for Suspicious e-Crime and Terrorist Account Detection

Retrieval of images with object-of-interest from a vast pool of social media images has been a research interest in cyber crime research community for detecting criminal behaviors in social media. Due to inherent diversity and the low duplicate property of images on social media, it brings forth many challenges in image retrieval, especially in identifying distinct features for a given object-of-interest. Previous literature approached this problem with extended General Hough Transform, where Hough space is analyzed for each specific object-of-interest. Different objects of interest produce different types of patterns in Hough space and no unified framework can be easily established to incorporate all those patterns. In this paper, we propose a unified framework based on convolutional neural network (CNN) for classifying the social media images and retrieving the images based on the probability score from the softmax classifier. In our framework, a reduced size CNN model is trained by distilling the knowledge from a pretrained full size CNN model, which is suitable for applications with limited training data such as ours and results in a higher accuracy in image retrieval as well as better performance in execution speed in comparison with the full size CNN model. Experiments on three image datasets relating to suspicious e-crime and terrorist involvement – Guy Fawkes masks, credit card logos, and ISIS logos show that our framework outperforms extended General Hough Transform and the full size CNN model.
UROGENITAL SINUS CALCULI IN A SAND TIGER SHARK (ODONTASPIS TAURUS)1

Two calculi were found in the urogenital sinus of a 70 kg female sand tiger shark (Odontaspis taurus). The calculi were white in color, rough surfaced, and spherical in shape. Crystallographic examination revealed that they were composed of magnesium ammonium phosphate hexahydrate (80% struvite) and calcium phosphate (15% carbonate apatite). Approximately 5% of the stone matrix consisted of blood and protein and a distinct bacterial nidus was not present microscopically.
The moderating effect of skills development transfer on organizational commitment – a case-study of Free State TVET colleges

One of the legacies of Apartheid South Africa which has ominous consequences for the economy, is the insidious dire skills shortage for majority of the citizens. Compelling government to embark on an intensive wholesale skills development to ameliorate and stimulate the general economic performance. This paper therefore, explored the relationship between employee organizational commitment and skills development transfer. A longitudinal study, with a preand post-quasi experimental research design was adopted in this paper employing Organizational Climate (OC) instrument to collect data from 59 randomly selected TVET college employees. The study revealed significant correlation between organizational commitment and skills development transfer. For example, appreciative of the access to training opportunities, involvement and frequency of training, sense of belonging, an indicative of the affective organizational commitment, with meagre 23% indicating intention to use acquired new skills to look for greener pastures elsewhere. This paper attempts to assist organizations better tailor their training provision to align it with certain desirable behavioral patterns, so as to enhance organizational commitment and reduce the turnover rate of staff.
Community participation and beneficiaries’ perceived sustainability of community and social development projects in Ibadan, Oyo state, Nigeria

Development interventions are often targeted at alleviating community challenges and enhancing livelihood sustainability. However, most intervention efforts usually have short-lived impacts and the projects often degenerate into nothingness. However, community participation has been fingered as one major tool that can ensure the sustainability of community development projects. This study therefore examined the effects of community participation on the sustainability of Community and Social Development Project (CSDP) in Ibadan, ThreecommunitiesOyo State, Nigeria. Multistage sampling procedure was used to select respondentsThree communities each from the urban, peri-urban and rural areas where CSDP had completed projects werepurposively selected for the study. A total of 168 respondents were randomly selected in these communities.Quantitative data on respondents’ age, sex, marital status, household size, community and social characteristicswere collected using interview schedule. Data were analysed using frequency counts, percentages and mean, aswell as PPMC and Chi-square. The mean age of respondents was 52.8±14.0 years; most (69.6%) of therespondents were males.More than one third of the respondents had tertiary education (43.5%). More than half(53.0%) of the respondents spent 2-5 hours in community development, (56.6%) participated in the project,(52.4%) were indigenes and (55.4%) were community project management committee (CPMC) members. Themean number of years spent in the community was 17.7±15.2 years. The area in which respondents participatedmost was sharing of idea ( X =2.39). while (55.4%) had high level of participation and (66.1%) indicated that theprojects had high sustainability. Significant (p<0.05) relationships exist between project sustainability (r=0.415),age (r=0.281), number of years of formal education (r=0.154, number of hours spent in community (r=0.469)and level of community participation in CSDP. Chi-square shows that significant (p<0.05) associations existbetween sex (χ2=9.721), type of community participation (χ2=26.820), status in the community (χ2=41.985) andlevel of community participation. It was observed that males participated more in community development thanfemales. Also, technical sustainability of projects was found to be low. Therefore efforts should be made toencourage youths to participate in community development.
BDNF-TrkB signalling in fear learning: from genetics to neural networks

Abstract Discovering the basic mechanisms in fear encoding and expression is important in many fields, including psychology, sociology, medicine, and neuroscience. Effective treatment for fear-based pathology depends on understanding how fear is learned and regulated. Among the molecular systems required for fear learning and amygdalar synaptic plasticity, brain derived neurtrophic factor (BDNF) and its high affinity receptor Ntrk2/TrkB have been shown to play essential roles. Therefore, we will focus this review on three main aspects; first of all, the impact of Bdnf polymorphism on fear related characteristics in humans and animal models. Secondly, we will discuss BDNF-TrkB activity regulation by epigenetic, transcriptional and post-translational events, and finally we will discuss TrkB-BDNF signalling in fear learning. BDNF-TrkB and the signalling activated in this particular form of plasticity are becoming crucial players in fear learning and memory thus highlighting these molecules as potential therapeutic targets in fear-related pathologies.
Work-Based Mobile Learning Environments: Contributing to a Socio-Cultural Ecology of Mobile Learning

This paper examines the idea of a Work Oriented Mobile Learning Environment WOMBLE and considers the potential affordances of mobile devices for supporting developmental and informal learning in the workplace. The authors look at the nature and pedagogy of work-based learning and how technologies are being used in the workplace for informal learning. The paper examines the nature of Work Process Knowledge and how individuals are shaping or appropriating technologies, often developed or designed for different purposes, for social learning at work. The paper goes on to describe three different use cases for a Work Oriented Mobile Learning Environment. The final section of the paper considers how the idea of the WOMBLE can contribute to a socio-cultural ecology for learning, and the interplay of agency, cultural practices, and structures within mobile work-based learning.
Inhibitory and cytotoxic activities of salvia officinalis L. Extract on human lymphoma and leukemia cells by induction of apoptosis.

PURPOSE Salvia officinalis L. , also known as Maryam Goli, is one of the native plants used to Persian medicinal herbs. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized crude methanol extracts prepared from Salvia officinalis L. , on a non-Hodgkin's B-cell lymphoma (Raji) and human leukemic monocyte lymphoma (U937), Human acute myelocytic leukemia (KG-1A) and Human Umbilical Vein Endothelial (HUVEC) cell lines. METHODS The effect of methanolic extract on the inhibition of cell proliferation and cytotoxic activity was evaluated by Dye exclusion and Micro culture tetrazolium test (MTT) cytotoxicity assay. Cell death ELISA was employed to quantify the nucleosome production result from nuclear DNA fragmentation during apoptosis and determined whether the mechanism involves induction of apoptosis or necrosis. RESULTS The present results demonstrated that methanolic extract at 50 to 800 μg/ml dose and time-dependently suppressed the proliferation of KG-1A, U937 and Raji cells by more than 80% (p<0.01), with ascending order of IC50 values in 24: KG-1A (214.377 μg/ml), U937 (229.312 μg/ml) and Raji (239.692 μg/ml) when compared with a chemotherapeutic anticancer drug, paclitaxel (Toxol), confirming the tumour-selective cytotoxicity. The crude extract however did not exert any significant cytotoxic effect on normal cell line HUVEC (IC50>800 Ag/ml). Nucleosome productions in KG-1A, Raji and U937 cells were significantly increased respectively upon the treatment of Salvia officinalis L. extract. CONCLUSION The Salvia officinalis L. extract was found dose and time-dependently inhibits the proliferation of lymphoma and leukemic cells possibly via an apoptosis-dependent pathway.
Characteristics of indolent non‐hodgkin lymphoma in patients with type 1 human immunodeficiency virus infection

There is recent evidence that the incidence of indolent non‐Hodgkin lymphoma (NHL) appears to be increased in persons with the acquired immunodeficiency syndrome (AIDS). The current study was conducted to describe the clinical, immunologic, and pathologic characteristics of indolent B‐cell lymphoma in patients infected with the human immunodeficiency virus (HIV).
A DOUBLE‐BLIND TRIAL OF ORAL ISOXUPRINE IN THE PREVENTION OF PREMATURE LABOUR

THE need for a reliable and safe method of preventing the premature onset of labour is beyond question. One-third of low birth weight babies reported in the Perinatal Mortality Survey were born before the 36th week (Butler and Bonham, 1963). A specific antenatal abnormality that makes premature delivery advisable is present in less than one-yuarter of births before the 37th week (Butler, 1965). Isoxuprine is a synthetic adrenalin-like substance which is known to inhibit human myometrial activity under certain circumstances (Hendricks et al., 1961; Allen et al., 1965). The principal side effects are tachycardia and hypotension which are mediated via the p-adrenergic receptors of the cardiovascular system. Myometrial inhibition is a papaverine-like action (Stander, 1966). Briscoe (1966), using 10 mg. orally four times a day in a double-blind clinical experiment, was unable to produce a significant difference in the incidence of prematurity between the Isoxuprine and placebo treated groups. Hawkins, however (personal communication), has shown that a much larger dose of Isoxuprine given orally can inhibit Braxton Hicks contractions in women. The dose used in our trial was three times greater than that used by Briscoe.
Approaches towards business process management adoption under different organizational cultures : doctoral dissertation

This study reviews the main research findings on BPM adoption in connection to organizational culture, specifically the different types of organizational culture defined by Cameron and Quinn (2006). The findings show there are only a handful of papers that discuss the relationship between the different organizational culture types and BPM adoption. These papers suggest there are significant differences in how different culture types impact the adoption of BPM. However, this topic is still under-researched. There is a gap in the empirical literature directly examining the correlation between culture types and process performance. In addition, the literature does not address the approach to BPM adoption under different culture types, although the importance of a fit between BPM and organizational culture is well recognised. Based on the structured literature review, a framework is proposed that shows the relationship between organizational culture, the approach to BPM adoption, and the success of BPM adoption. The framework can serve as a starting point for structuring future research on this topic, which is necessary to gain a better understanding of the relationship between the different organizational culture types and BPM adoption. Ultimately, these findings could help improve the success rate of BPM projects in practice.

STATISTICAL STUDY ON THE DECAY PHASE OF SOLAR NEAR-RELATIVISTIC ELECTRON EVENTS

We study the decay phase of solar near-relativistic (53–315 keV) electron events as observed by the Advanced Composition Explorer (ACE) and the Ulysses spacecraft during solar cycle 23. By fitting an exponential function (exp − t/τ) to the time–intensity profile in the late phase of selected solar near-relativistic electron events, we examine the dependence of τ on electron energy, electron intensity spectra, event peak intensity, event fluence, and solar wind velocity, as well as heliocentric radial distance, heliolatitude, and heliolongitude of the spacecraft with respect to the parent solar event. The decay rates are found to be either independent or slightly decrease with the electron energy. No clear dependence is found between τ and the heliolongitude of the parent solar event, with the exception of well-connected events for which low values of τ are more commonly observed than for poorly-connected events. For those events concurrently observed by ACE and Ulysses, decay rates increase at distances >3 AU. Events with similar decay rates at ACE and Ulysses were observed mainly when Ulysses was at high heliographic latitudes. We discuss the basic physical mechanisms that control the decay phase of the electron events and conclude that both solar wind convection and adiabatic deceleration effects influence the final shape of the decay phase of solar energetic particle events, but not as expressed by the models based on diffusive transport acting on an isotropic particle population.
Hemodynamic effects of ventricular defibrillation.

Hemodynamic responses to ventricular defibrillation were studied in anesthetized dogs. Observations were made on arterial, right atrial and left ventricular end-diastolic pressures, on cardiac output (dye dilution), heart rate, and right atrial electrocardiogram. Ventricular fibrillation was induced electrically with a bipolar electrode catheter placed in the right ventricle. Fibrillation was maintained for 15 or 30 sec and terminated with a 400 w sec capacitor discharge across the thoracic cage. Responses lasted 1-10 min after conversion and included a cholinergic and an adrenergic component. The cholinergic component was characterized by sinus bradycardia, periods of sinus arrest, atrioventricular block, and ventricular premature beats. The adrenergic component included increases in arterial pressure, in cardiac output, and in left ventricular stroke work at a time when left ventricular end-diastolic pressure was normal; there was no change in total peripheral resistance. The pH of arterial blood decreased slightly and pCO(2) increased but pO(2) and the concentration of lactate were unchanged. Bilateral vagotomy and intravenous administration of atropine blocked the cholinergic component, unmasked a sinus tachycardia, and accentuated the adrenergic component of the response. The latter was blocked by intravenous administration of propranolol and phenoxybenzamine.THESE RESPONSES WERE RELATED PRIMARILY TO CONVERSION OF VENTRICULAR FIBRILLATION RATHER THAN TO THE ELECTRICAL DISCHARGE OF COUNTERSHOCK BECAUSE COUNTERSHOCK WITHOUT VENTRICULAR FIBRILLATION CAUSED MORE TRANSIENT AND SMALLER RESPONSES THAN THOSE OBSERVED WITH DEFIBRILLATION: furthermore, the hemodynamic effects of defibrillation were augmented by prolongation of the duration of fibrillation. The results suggest that the cholinergic component of the response may be detrimental in that it favors spontaneous recurrence of fibrillation; on the other hand, the adrenergic component may be essential for conversion since only one of six dogs depleted of endogenous catecholamines with reserpine survived ventricular defibrillation.
Investigating Supply Chain Relationships with suppliers and customers for mass customization

The influence of information technology (IT) is exceeding the providing of financial and operating support to including strategic initiatives in knowledge management and long-range planning. IT is being used to facilitate customer and supplier involvement in designing specialized product offerings, implementing process improvements, enhancing manufacturing flexibility, and controlling manufacturing operations. Together, these advances are enabling firms to customize their product offerings mass customization (MC) and marketing at prices close to those quoted by traditional mass producers. While much research on MC has been reported in the literature, empirical studies investigating the impact of IT on creating cooperative and integrative relationships with customers and suppliers and the impacts of these relationships on the level of MC, are sparse and represent a missing link in manufacturing research. Using data collected from 220 manufacturers, this study finds that firms with higher levels of cooperative relationships with suppliers and customers enjoy higher levels of mass customization than firms that do not.
The afferent pathway of the Bezold reflex: the right vagal branches in cats.

In 1867 von Bezold and Hirt showed that intravenous injection of veratrum alkaloids caused a fall of blood pressure and heart rate, which was abolished by cutting the vagi. They attributed the phenomenon to an action on receptors in the heart. The principal physiological interest of the Bezold reflex lies in the nature of these receptors, and before these can be identified the afferent pathway of the reflex must be established with certainty. In 1939 Jarisch and Richter investigated the afferent pathway of the reflex in cats. On the right side they concluded that it lay among a group of nerves which leave the vagus just as it crosses the right subclavian artery, and which run beneath the aortic arch toward the ventricles; on the left side it was not clearly defined. However, Amann and Schaeffer (1943) observed an increase in the discharge frequency of vagal branches from the right atrium after administration of veratrine, and in 1948 Jarisch and Zottermann concluded from similar observations that these branches contain the Bezold afferent nerve fibres. There is therefore a discrepancy in the evidence for the afferent pathway of the reflex. This paper describes experiments to identify the afferent nervous pathway of the Bezold reflex on the right side in cats. The effects of stimulation of the central ends of these nerves, and of the application bf a cold block to the vagus in the neck are also described.
Background discharge and evoked responses of spinal interneurones

The preceding paper (Hunt & Kuno, 1959) dealt with properties of spinal interneurones and mechanisms of synaptic excitation of such cells. The present study is concerned with an analysis of the background discharge of interneurones, the modulation of discharge by natural exteroceptive stimulation, and the response to nerve volleys from various peripheral sources. All these features of interneurone behaviour have been studied previously. Background discharge of interneurones has been noted by a number of authors (Frank & Fuortes 1955, 1956; Kolmodin 1957; Haapanen, Kolmodin & Skoglund 1958; Kolmodin & Skoglund 1958). Kolmodin (1957) has studied extensively the patterns of response of interneurones to muscle stretch and to a lesser extent to natural exteroceptive stimulation. Finally, several authors (Woodbury & Patton 1952; Frank & Fuortes 1955, 1956; Haapanen et al. 1958) have published some examples of the responses of interneurones to afferent volleys. The present study provides new information on these aspects of interneurone behaviour. The background discharge has been studied by an analysis of frequency distribution of impulse intervals, responses to natural exteroceptive stimulation have been subject to more extensive study, and a systematic study has been made of responses to nerve volleys from various peripheral sources. The interneurones that respond by highfrequency trains of impulses to antidromic volleys in ventral root fibres have been studied in detail (Renshaw, 1946; Eccles, Fatt & Koketsu 1954) and are not included in the present report.
Antecedents of positive self-disclosure online: an empirical study of US college students’ Facebook usage

This study investigates the factors predicting positive self-disclosure on social networking sites (SNSs). There is a formidable body of empirical research relating to online self-disclosure, but very few studies have assessed the antecedents of positive self-disclosure. To address this literature gap, the current study tests the effects of self-esteem, life satisfaction, social anxiety, privacy concerns, public self-consciousness (SC), and perceived collectivism on positive self-disclosure on SNSs. Data were collected online via Qualtrics in April 2013. Respondents were undergraduate students from the University of Connecticut. Using ordinary least squares regression, the current study found that self-esteem and perceived collectivism increased positive self-disclosure, life satisfaction, and privacy concerns decreased positive self-disclosure, and the effects of social anxiety and public SC were not significant.
