Cultivation and Counter Cultivation: Does Religiosity Shape the Relationship between Television Viewing and Estimates of Crime Prevalence and Assessment of Victimization Likelihood?
Authors: Hetsroni Amir , Lowenstein Hila
Published: March 2013

Religiosity may change the direction of the effect of TV viewing on assessment of the likelihood of personal victimization and estimates concerning crime prevalence. A content analysis of a representative sample of TV programming (56 hours of prime-time shows) was done to identify the most common crimes on television, followed by a survey of a representative sample of the adult public in a large urban district (778 respondents) who were asked to estimate the prevalence of these crimes and to assess the likelihood of themselves being victimized. People who defined themselves as non-religious increased their estimates of prevalence for crimes often depicted on TV, as they reported more time watching TV (ordinary cultivation effect), whereas estimates regarding the prevalence of crime and assessment of victimization likelihood among religious respondents were lower with reports of more time devoted to television viewing (counter-cultivation effect).
Assessing Empathy in Antisocial Youth: Factor Analytic and Validation Findings
Authors: Whitt Ahmed , Howard Matthew O.
Published: March 2013

Relatively few researchers have examined empathy among antisocial youth, although adolescents may differ greatly in the nature and frequency of their offending behavior. In this investigation, exploratory and confirmatory factor analysis were used (1) to derive a brief empathy scale from the Psychopathic Personality Inventory–Short Version; (2) to assess the construct validity, internal consistency, and potential clinical utility of the derived empathy subscale; and (3) to identify key sociodemographic, psychosocial, and behavioral correlates of empathy in delinquent youth. The 707 adolescent residents of 27 Missouri Division of Youth services rehabilitation facilities had a mean age of 15.5 yr. ( SD = 1.2) and most (87%) were boys. Analysis suggested that the new measure possesses adequate psychometric properties and may be a useful addition to clinical assessments of antisocial youth.
Effects of Daylight-Saving Time Changes on Stock Market Returns and Stock Market Volatility: Rebuttal
Authors: Kamstra Mark J. , Kramer Lisa A. , Levi Maurice D.
Published: March 2013

In a 2011 reply to our 2010 comment in this journal, Berument and Dogen maintained their challenge to the existence of the negative daylight-saving effect in stock returns reported by Kamstra, Kramer, and Levi in 2000. Unfortunately, in their reply, Berument and Dogen ignored all of the points raised in the comment, failing even to cite the Kamstra, et al. comment. Berument and Dogen continued to use inappropriate estimation techniques, over-parameterized models, and low-power tests and perhaps most surprisingly even failed to replicate results they themselves reported in their previous paper, written by Berument, Dogen, and Onar in 2010. The findings reported by Berument and Dogen, as well as by Berument, Dogen, and Onar, are neither well-supported nor well-reasoned. We maintain our original objections to their analysis, highlight new serious empirical and theoretical problems, and emphasize that there remains statistically significant evidence of an economically large negative daylight-saving effect in U.S. stock returns. The issues raised in this rebuttal extend beyond the daylight-saving effect itself, touching on methodological points that arise more generally when deciding how to model financial returns data.
Exploring the Relationships between Fear-Related Xenophobia, Perceptions of Out-Group Entitativity, and Social Contact in Norway
Authors: Ommundsen Reidar , Yakushko Oksana , Van Der Veer Kees , Ulleberg Pål
Published: March 2013

An internet-related survey distributed to Norwegian students explored predictors of fear-related xenophobia toward immigrants. Specifically, this study examined a new social construct called “entitativity” (i.e., the extent to which out-group members are perceived as bonded together in a cohesive or organized unit), as well as frequency of informal social contact and valence of a recent encounter in relation to certain xenophobic attitudes. Correlational and multiple regression analyses indicated that perceived out-group entitativity was a moderate predictor of fear-related xenophobia. Voluntary informal contact was a weak predictor of fear-related xenophobia, whereas negative evaluation of an encounter in the recent past was a strong predictor. Further analysis indicated that the effect of entitativity on xenophobia was strongest when informal social contact was low. Moreover, analysis indicated that the effect of valenced contact was partly mediated through perception of entitativity.

Authors: Liu Haihua , Shi Junqi , Liu Yihao , Sheng Zitong
Published: March 2013

This study examined the moderating role of attachment anxiety on the relationship between intensity of social network site use and bridging, bonding, and maintained social capital. Data from 322 undergraduate Chinese students were collected. Hierarchical regression analyses showed positive relationships between online intensity of social network site use and the three types of social capital. Moreover, attachment anxiety moderated the effect of intensity of social network site use on social capital. Specifically, for students with lower attachment anxiety, the relationships between intensity of social network site use and bonding and bridging social capital were stronger than those with higher attachment anxiety. The result suggested that social network sites cannot improve highly anxiously attached individuals' social capital effectively; they may need more face-to-face communications.

Authors: Golmankhaneh Alireza , Golmankhaneh Ali , Baleanu Dumitru
Published: March 2013

In this paper we have generalized $$F^{\bar \xi }$$-calculus for fractals embedding in ℝ3. $$F^{\bar \xi }$$-calculus is a fractional local derivative on fractals. It is an algorithm which may be used for computer programs and is more applicable than using measure theory. In this Calculus staircase functions for fractals has important role. $$F^{\bar \xi }$$-fractional differential form is introduced such that it can help us to derive the physical equation. Furthermore, using the $$F^{\bar \xi }$$-fractional differential form of Maxwell’s equations on fractals has been suggested.

Authors: Mehdinia Ali , Dejaloud Minodokht , Jabbari Ali
Published: March 2013

An approach for improving the power generation of a dual-chamber microbial fuel cell by using a nanostructured polyaniline (PANI)-modified glassy carbon anode was investigated. Modification of the glassy carbon anode was achieved by the electrochemical polymerisation of aniline in 1 M H2SO4 solution. The MFC reactor showed power densities of 0.082 mW cm−2 and 0.031 mW cm−2 for the nano- and microstructured PANI anode, respectively. The results from electron microscopy scanning confirmed formation of the nanostructured PANI film on the anode surface and the results from electrochemical experiments confirmed that the electrochemical activity of the anode was significantly enhanced after modification by nanostructured PANI. Electrochemical impedance spectroscopic results proved that the charge transfer would be facilitated after anode modification with nanostructured PANI.
Effect of flow-rate on ethanol separation in membrane distillation process
Authors: Gryta Marek
Published: March 2013

The separation of diluted ethanol solutions and fermentation broths by membrane distillation was investigated. The influence of stream flow-rate on the ethanol flux was studied. An evaluation of the process conditions on the separation degree of ethanol was performed with the application of hydrophobic capillary membranes composed of polypropylene. By removing the alcohol via membrane distillation, it is possible to achieve a higher content of ethanol in the permeate than that in the broth. The enrichment coefficient amounted to 4–6.5, and decreased with an increase of the ethanol concentration in the broth. It was found that the flow-rate affects the value of the enrichment coefficient. A positive influence of carbon dioxide on the ethanol transport through the capillary membrane was observed. The evolution of CO2 bubbles from the broth increases the stream turbulence, probably enhancing the alcohol concentration in the layer adjacent to the membrane surface.

Authors: Abdellah Zahra Nait , Keddam Mourad , Elias Abdelhamid
Published: March 2013

In this work, the effective diffusion coefficient of boron in the Fe2B phase was evaluated by considering the effect of chemical stresses in the case of paste-boriding of AISI 4140 steel. Two kinetic approaches were proposed to evaluate the diffusion coefficient of boron in the Fe2B phase in the temperature range of 1 123–1 273 K, and considering the effect of the boride incubation times. By applying the mass balance equation at the (Fe2B/substrate) interface and the theory of elasticity, it is possible to determine the effective diffusion coefficient of boron in the Fe2B phase. The obtained value of activation energy of boron diffusion in the presence of chemical stresses was estimated as 158.78 kJ mol−1 using the experimental parabolic growth constants taken from the literature. In addition, the simulated values of effective diffusion coefficients of boron in the Fe2B phase are found to be sensitive to the change in the boriding temperature and to the increase in the upper boron content in the Fe2B phase within its composition range

Authors: Natalini M. , Sasso M. , Amodio D.
Published: March 2013

Warpage reduction, dimensional tolerance accomplishment and time and cost saving are some of the most important problems in the injection molding production process. In this study, a real case of a thermoplastic injected part is analyzed. The mold for a pipeline connecting element has been designed, according to known technical and economical criterion to fulfill customer requirements. Particularly for this element, warpage of a specified surface and two diameter sizes are fundamental for correct part functionality and assembling. The analysis is centered on the effects of four process parameters, i. e. packing pressure, packing time, melt temperature and cooling time that heavily influence final results. A finite element model has been used to evaluate their effects on four important final objectives that are the geometrical entities and production cycle time. Each variable has been varied into its proper range, in accordance with a central composite design DoE plan; 25 simulations have been executed and results have been represented using response surfaces. Pareto Front for above listed objectives has been extracted using a genetic algorithm and the best set of parameters has been determined after application of specific selection criteria and a weighted objective function. After numerical evaluation, the CCD DoE plan has been experimentally repeated. Results have been measured on real components, and then represented with response surfaces as well. The same algorithm and objective function have been used for optimization, to determine the experimental optimum parameter set. Finally, the two parameter sets have been compared.
History of Clinical Research and Ethics
Authors: Lasker Shamima Parvin
Published: March 2013

The aim of clinical research is to congregate useful knowledge about the human biology. Benefits to the participants are not the purpose of research, although it does secondarily. Therefore, exploitation of human subjects occurred in clinical research. Many people were harmed and basic human rights were violated as a result of their unwillingness participation in research. There have been many tragedies throughout the history of research involving human subjects. Every period of research scandals have been followed by attempt to initiate some ethical codes to protect the human from clinical research. First of such codes is the Nuremberg Code. Thereafter, Helsinky Declaration, Belmont Report and lastly Obama Commission on Guatemala syphilis study. To remember history is essential so that it's not repeated again. Knowledge of the history will provide a better understanding to handle the research fairly. Researchers and the healthcare providers have no awareness of the history of ethical requirements for clinical research. Therefore, repetition of scandal is being seen. In addition, there are few sporadic studies on this issue. Formulation of UNIVERSAL rules and regulations is required which will not be limited to a specific tragedy or scandal or the practice of researcher in one country. It will provide common understanding and unique values of the research all over the world, although their application will require adaptation to particular culture, health condition and economic setting.

Scientific Freedom & Limits - Clinical Research Perspective
Authors: Fakruddin Md , Chowdhury Abhijit , Hossain Md Nur , Mannan Khanjada Shahnewaj Bin
Published: March 2013

Being a scientist, especially a clinical research one, is a noble but tough job. Scientific job is different from other jobs in terms of working hour and pressure; they need more freedom in their job & research that also put lots of responsibility on them. Research is funded by public money and it is the responsibility of scientists to gain maximum output from it. Clinical research is very complex and involves the use of animal, microbial as well as human samples and volunteers which make it more prone to ethical scrutiny. Minority of researchers who commit fraudulent use of public money & unethical clinical practice threaten public support for science. Now a day, there is growing concern of public and politicians on the freedom of scientists and unethical scientific practice in clinical trials. The most efficient measures to prevent scientific misconduct are awarenessnotably, self-awareness education and transparency. Most of the developed countries have formulated their own guidelines to ensure proper utilization and ethical clinical research and trials. Bangladesh is still lagging behind in terms of regulation and monitoring of clinical research and trials. This review aims to make related peoples to be aware of the necessity of its own guidelines for clinical research and trials.

‘Only in the Leap from the Lion's Head Will He Prove His Worth’: Natural Law and International Relations
Authors: Beattie Amanda Russell
Published: March 2013

This article argues the benefits of including a theological interpretation of natural law morality within the normative discourses of international politics. It challenges the assumption of a Grotian secular natural law arguing that practical reason, in a Thomist interpretation, is better suited to the demands of international political theory. It engages with themes of agency, practical reason, and community in order to enhance the content of the post-territorial community evidenced in ethical cosmopolitan debates. Likewise, it envisions simultaneously enhancing a rapprochement among cosmopolitan and communitarian discourses of international politics facilitated through an institutional design guided by the morality of natural law.
Cosmopolitan Regard, Motivation, and Multiple Jurisdictions
Authors: Jones Charles
Published: March 2013

This article identifies some core features of the argument in Richard Vernon's Cosmopolitan Regard: Political Membership and Global Justice (2010) and suggests some directions to pursue in defending its conclusions against reasonable objections. I outline the book's key ideas and draw attention to two areas in which Vernon's argument might be open to question. The first issue is that Vernon seems too quick with the problem of motivation, and the second is that his commitment to multiple jurisdictions must be careful not to beg the question. In the end, I claim these objections can be answered.
Iterative Contractualism? Global Justice and the Social Contract
Authors: Lecce Steven
Published: March 2013

This article assesses Richard Vernon's attempted reconciliation of compatriot preference with global justice by analyzing the iteration proviso (IP), which says that a group of people can legitimately set out to confer special advantages upon each other if others, outside that group, are free to do the same in their own case. Part I outlines how duties to outsiders are typically characterized in two leading accounts of global justice — moral universalism and associativism. The IP is motivated by Vernon's desire to transcend the binary opposition between, and the limitations of, these two views. Part II sketches the version of contractualism that Vernon deploys to surmount these limitations and explains the role of the IP therein. Part III elucidates two different interpretations of the IP and shows that neither seems plausible.
Cosmopolitan Regard and the Particularity Problem
Authors: Hibbert Neil
Published: March 2013

This paper addresses Richard Vernon's approach to reconciling cosmopolitan political morality with particularized political obligations in his work, Cosmopolitan Regard. It situates his approach in his critical treatment of competing transactional theories of obligation, particularly reciprocity for benefits received, and presents his justification of particularized political obligations towards fellow members of persons' own state, based on complicity in unique systems of risk exposure. The paper also presents a critical treatment of his theory, and goes on to outline an alternate conception of legitimacy without obligation as promising in addressing the identified concerns and as applicable to structures of governance beyond the state.
Regarding Cosmopolitanism
Authors: Vernon Richard
Published: March 2013

This article attempts to respond to the major critical themes in the commentaries by Jones, Hibbert and Lecce on the book Cosmopolitan Regard. The book's ‘statist’ assumptions are acknowledged, and defended in light of the project that is undertaken. Its use of an un-sociological notion of legitimacy (in contrast to ‘justification’) is explained. Its argument is characterized as one that seeks to constrain agency rather than to prescribe distributive outcomes of a strongly egalitarian kind. Finally, the argument's dependence on empirical assumptions is recognized.

Published: March 2013

The potent anti-inflammatory activities and tissue-protective effects of freshwater clams (Corbicula fluminea) have been well reported. The aim of this study was to determine the effects of freshwater clam extract (FCE) supplementation on time to exhaustion, muscle damage, pro- and anti-inflammatory cytokines, and liver injury in rats after exhaustive exercise. Thirty-two rats were divided into four groups: sedentary control (SC); SC group with FCE supplementation (SC+FCE); exhaustive exercise (E); and E group with FCE supplementation (E+FCE). The SC+FCE and E+FCE groups were treated with gavage administration of 20 mg/kg for seven consecutive days. Blood samples were collected for the evaluation of biochemical parameters. The cytokine levels of TNF-α and IL-10 were also examined. Twenty-four hours after exhaustive exercise, the rat livers were removed for H & E staining. The FCE supplementation could extend the time to exhaustion in exercised rats. The levels of CPK, LDH, AST, ALT, lactate, TNF-α and H & E stains of the liver injury were significantly decreased in the E+FCE group, but the blood glucose and IL-10 were significantly higher in comparison with the E group. This study suggests that FCE supplementation may improve endurance performance and reduce exercise-induced muscle damage, inflammatory stress and liver injury.
Design of siRNA Therapeutics from the Molecular Scale
Authors: Angart Phillip , Vocelle Daniel , Chan Christina , Walton S.
Published: March 2013

While protein-based therapeutics is well-established in the market, development of nucleic acid therapeutics has lagged. Short interfering RNAs (siRNAs) represent an exciting new direction for the pharmaceutical industry. These small, chemically synthesized RNAs can knock down the expression of target genes through the use of a native eukaryotic pathway called RNA interference (RNAi). Though siRNAs are routinely used in research studies of eukaryotic biological processes, transitioning the technology to the clinic has proven challenging. Early efforts to design an siRNA therapeutic have demonstrated the difficulties in generating a highly-active siRNA with good specificity and a delivery vehicle that can protect the siRNA as it is transported to a specific tissue. In this review article, we discuss design considerations for siRNA therapeutics, identifying criteria for choosing therapeutic targets, producing highly-active siRNA sequences, and designing an optimized delivery vehicle. Taken together, these design considerations provide logical guidelines for generating novel siRNA therapeutics.
From Talloires to Turin: A Critical Discourse Analysis of Declarations for Sustainability in Higher Education
Authors: Sylvestre Paul , McNeil Rebecca , Wright Tarah
Published: March 2013

Declarations for sustainability in higher education are often seen as a set of guiding principles that aid institutions of higher learning to incorporate the concept of sustainability into their various institutional dimensions. As the Decade of Education for Sustainable Development draws to a close and in the shadow of the 20th anniversary of the Earth Summit in Rio de Janeiro, it seems appropriate to re-evaluate how these declarations have changed over the past two decades. In this study, we apply critical discourse analysis to examine how sustainability and the university are socio-politically constructed within these documents. Our analysis uncovers evidence of ideological assumptions and structures that are potentially misaligned with notions of sustainability often discussed in the Sustainability in Higher Education (SHE) literature. It is not the purpose of this study to provide a definitive reading of the documents, but rather to ply a novel critical lens to help elucidate how some taken-for-granted assumptions present in the declarations may work against their stated goals.

Authors: Sujatanond Supamard , Miyashita Yukio , Hashimura Shinji , Mutoh Yoshiharu , Otsuka Yuichi
Published: March 2013

The bolt load loss behavior of AZ91D magnesium alloy bolted joints with a conventional SCM435 steel bolt and an A5056 aluminum bolt was investigated at elevated temperature. The A5056 bolt could reduce the bolt load loss compared to the SCM435 bolt due to smaller mismatch of thermal expansion between the bolt material and the plates. The mismatch of thermal expansion between bolt material and AZ91D plates was found to induce the compressive creep deformation in the AZ91D plates which performed as the main mechanism of bolt load loss. At higher tightening stress, the bolt load loss could be intensified by additional plastic deformation in bolt occurred during the test. Moreover, it is suggested that the plastic deformation could be reduced by decreasing the friction condition in the bolted joint.

Published: March 2013

In order to effectively inhibit the influence of constant bias of inertial sensors on strapdown inertial navigation system accuracy, a self-compensation method based on single-axis rotation modulation is proposed.

Effect of Rotational Flow on the Inclusion Behavior in Industrial Tundish for Steel Production
Authors: Wang Yun , Jia Huan Li
Published: March 2013

Numerical simulation was applied to study the inclusion behavior in the rotational flow tundish for the industrial production of steel. Results showed that the rotational flow prolonged the trajectory of inclusion movement and thus promoted the inclusion removal. Meanwhile the large turbulent fluctuation caused by rotational flow greatly promoted the removal of smaller inclusions which were hard to be removed generally. However high rotation speed was not recommended since it led to the short flotation time for inclusions and meantime reduced the removal rate of larger inclusions by turbulence disturbance.

Published: March 2013

The mineralization of soil carbon materials potentially alters carbon release from soil and the atmospheric carbon concentration in engineering. Despite this central role in the decomposition of soil carbon materials, few studies have been conducted on how climate warming affects this carbon emissions and then response in return back. To study this, five soils were incubated in 5, 15, 25 °C for one month. Soil shifted to warming condition slowed down the increasing rate of decomposition causing by higher temperature. Furthermore, raising the soil environment temperature to 25 °C weakened the temperature sensitivity of the decomposition of these carbon materials, and the temperature sensitivity enhanced at lower temperature. This “thermal adaptation” of carbon material would potentially slow down carbon loss which accelerated by climate change technically.
