Previous research has shown that technology design and technology usage behavior is gendered: men and women position themselves in relation to technology based on femininity and masculinity norms (Aaltojarvi, 2012; Akrich, 1992; Green, 2002; Kelan, 2007; Oost, 2000; Rakow, 1988; Shade, 2007; Taipale & Fortunati, 2014). We use a social constructionist view and discourse analysis to look at how German men and women position themselves in relation to the mobile phone in private and occupational life. Our findings uncover strong gender dimensions in the discourse around mobile communication technology and indicate the emergence of practices that weave gender and technology together in new ways.
The Secure Access Node Project: A Hardware-Based Large-Scale Security Solution for Access Networks

—Providing network security is one of the most important tasks in todays Internet. Unfortunately, many users are not able to protect themselves and their networks. Therefore, a novel security concept is presented to protect users by providing security measures at the Internet Service Provider level. Already now, Internet Service Providers are using different security measures, e.g., Virtual Local Area Network tags, MAC limitation, or MAC address translation. The presented approach extends these security measures by three hardware-based security subsystems. A ﬁrewall engine controls the header of Ethernet frames, Internet packets, and the next following protocols. Furthermore, a Web ﬁlter module disables access to violent and child pornography Web content. The third subsystem is a Bloom ﬁlter-based deep packet inspection engine to observe the payload after the protocol header. Based on deep packet inspection, it is possible to detect network intruder. A ﬁrewall, a Web ﬁlter as well as a network intrusion detection system, at the ingress of the network, offer security measures to all connected users, especially to users with limited IT expert knowledge. Each of the mentioned systems has a powerful packet classiﬁcation engine and a high speed rule set engine used by the ﬁrewall to ﬁnd speciﬁc rules for each frame. The rule set engine does not need expensive content addressable memory. All described ﬁlter modules as well as the packet classiﬁcation engine and the rule set engine are developed in reconﬁgurable hardware. Thus, rule updates and adjustments to the hardware are easy to realize. Adjustments can be made only by the Internet Service Provider administrator. Consequently, the security system itself is secured against attacks from users and from the network side. This novel security approach allows for the protection of up to 32,000 Internet users in wire speed. Furthermore, the prototype system is able to process network trafﬁc at wire speed.

University-Community Partnerships: Bridging People and Cultures in an HIV/AIDS Health Intervention in an African American Community

As universities become more involved in real-world problems that affect racial and ethnic communities, university members are identifying strategies to effectively work with culturally diverse community partners. The Communities and Health Disparities Project described in this article is an example of collaborative scholarship that engages the university, a community-based organization, and members of the African American community. The purpose of the project was to develop a culturally tailored toolkit to correct misinformation about HIV/AIDS. In this article, the authors identify five strategies for building relationships across diverse cultural groups: connecting with cultural insiders, building collegiality, developing shared aims and goals, recognizing diverse skills and expertise, and sustaining commitments. The authors provide a conceptual framework that integrates the Freirian philosophy and the scholarship of engagement.
Critical role for p53-serine 15 phosphorylation in stimulating transactivation at p53-responsive promoters

The p53 tumour suppressor is induced by various stress stimuli and coordinates an adaptive gene expression programme leading to growth arrest or cell death. Some stimuli, such as DNA damage, lead to rapid and substantial multisite phosphorylation of p53, nucleated initially through phosphorylation of serine 15. Other stimuli, such as hyper-proliferation, do not stimulate p53-phosphorylation, raising questions regarding the physiological role for phosphorylation. Here, we show that a basal level of Ser15 phosphorylation occurs in both unstimulated cells and cells stimulated pharmacologically to induce p53. p53 in which Ser15 is substituted by alanine (S15A) fails to mediate p53-dependent transcription or growth arrest but can be rescued by substitution with aspartate (S15D: a phospho-mimic). Chromatin immunoprecipitation (ChIP) analyses show that, while wt- and S15A-p53 are detectable on the CDKN1A (p21) promoter (as a representative p53-responsive promoter), S15A-p53 does not stimulate histone acetylation (a measure of chromatin relaxation), nor is its recruitment stimulated, in response to a DNA damage or pharmacological stimulus. These data demonstrate that Ser15 phosphorylation is required for p53 function in the physiological context of p53-responsive promoters and suggest a key and possibly universal role even for low levels of this modification in promoting p53-transcription function.
The carcinogenicity of compounds related to 2-acetylaminofluorene. III. Aminobiphenyl and benzidine derivatives.

1. The carcinogenic activities for the rat of 4-acetylaminobiphenyl, N,N′-diacetylbenzidine, and eighteen related compounds have been investigated. The compounds were administered orally for 8–10 months. 2. Under these conditions 4-acetylaminobiphenyl induced a high incidence of adenocarcinomas of the mammary gland in female rats and small numbers of adenocarcinomas of the small intestine and squamous-cell carcinomas and sebaceous gland carcinomas of the ear duct. In addition to these tumors, 4′-fluoro-4-acetylaminobiphenyl induced a high incidence of liver tumors in male rats at 10–12 months. 3. 3-Hydroxy-4-aminobiphenyl and its N-acetyl derivative were noncarcinogenic. These compounds do not appear to be the effective carcinogen when 4-aminobiphenyl or its N-acetyl derivative is administered. 4. The following compounds had little or no carcinogenic activity under our conditions: 2-methyl-, 2′-methyl-, 2′-fluoro-, and 3-amino-4-acetylaminobiphenyl; 3-amino-4-dimethylaminobiphenyl; 2- and 3-acetylaminobiphenyl; 4-fluorobiphenyl; 4-acetylamino- p -terphenyl; acetanilide; and 3,4-dimethylacetanilide. 5. Rats fed N,N′-diacetylbenzidine developed a fatal glomerulonephritis which prevented adequate tests for carcinogenic activity. 2-Methyl-N,N′-diacetylbenzidine had moderate carcinogenic activity similar to that of 4-acetylaminobiphenyl; 3,3′-dimethyl-N,N′-diacetylbenzidine had weak activity; and 2,2′-dimethyl-N,N′-diacetylbenzidine was inactive. 6. The syntheses of the following new compounds are described: 3-hydroxy-4-aminobiphenyl, 3-hydroxy-4-acetylaminobiphenyl, and 2′-fluoro-4-acetylaminobiphenyl.
A compiler method for memory-conscious mapping of applications on coarse-grained reconfigurable architectures

This paper presents a compiler methodology for memory-aware mapping on 2-Dimensional coarse-grained reconfigurable architectures that aims in improving the mapped applications' performance. By exploiting data reuse opportunities, the methodology tries to overcome the data memory bandwidth bottleneck, which negatively influences the applications' performance. This is achieved by using foreground memory in the architecture and by properly placing operations in the processing elements. The methodology considers a realistic 2-Dimensional coarse-grained reconfigurable architecture template, which can model the majority of the existing coarse-grained architectures. The experimental results show that the execution time and memory accesses are reduced.
1 Using CSPs to encode TMSs

A truth maintenance system (TMS) is a general problem solving facility designed to work in tandem with an inference engine. Justification-based TMSs (the most commonly used TMSs) have not a sufficient expressive power for many applications. Logic-based TMSs overcome this limitation but are untractable. So, McAllester, or Forbus and de Kleer have proposed to encode formulae in clauses and to run the efficient Boolean Constraint Propagation algorithm (BCP), what lose the completeness of the deductions. In this paper, we introduce the model of Constraint Satisfaction Problems (CSPs) underlining that the notion of local completeness (called local-consistency in CSPs) has already been widely treated in CSPs. We then propose an encoding of McAllester's TMS in Dynamic CSP to be able to use CSPs techniques. We show that not only we can compute as many deductions as BCP for the same timeconsuming, but also we can outperform the local completeness computed for a slight more running-time. Finally, we say that we can run other well known CSPs techniques dealing with the disposition of the constraints between them to solve with a good improvement the central problem in TMSs: finding all contradictions.
Ethnography in a virtual world

This article situates the discussion of virtual ethnography within the larger political/economic changes of twenty-first century consumer capitalism and suggests that increasingly our entire social world is a virtual world and that there were very particular utopian and dystopian framings of virtual community growing out of that history. The article also situates the discussion of virtual ethnography within the anthropological ‘crisis of representation’ discussion to suggest there are many parallels between the two discussions. These discussions suggest that while ethnographers have recognised that all societies are virtual except, maybe the smallest, new information technologies, and particularly, the Internet create a persistent virtual space that transforms earlier notions of the imagined society. Finally, the article suggests that educational ethnographers are in a position to discuss the new pedagogical issues that arise when attempting to do ethnography in our contemporary virtual world.
Subepicardial Action Potential Characteristics Are a Function of Depth and Activation Sequence in Isolated Rabbit Hearts

Background—Electric excitability in the ventricular wall is influenced by cellular electrophysiology and passive electric properties of the myocardium. Action potential (AP) rise time, an indicator of myocardial excitability, is influenced by conduction pattern and distance from the epicardial surface. This study examined AP rise times and conduction velocity as the depolarizing wavefront approaches the epicardial surface. Methods and Results—Two-photon excitation of di-4-aminonaphthenyl-pyridinum-propylsulfonate was used to measure electric activity at discrete epicardial layers of isolated Langendorff-perfused rabbit hearts to a depth of 500 &mgr;m. Endo-to-epicardial wavefronts were studied during right atrial or ventricular endocardial pacing. Similar measurements were made with epi-to-endocardial, transverse, and longitudinal pacing protocols. Results were compared with data from a bidomain model of 3-dimensional (3D) electric propagation within ventricular myocardium. During right atrial and endocardial pacing, AP rise time (10%–90% of upstroke) decreased by ≈50% between 500 and 50 &mgr;m from the epicardial surface, whereas conduction velocity increased and AP duration was only slightly shorter (≈4%). These differences were not observed with other conduction patterns. The depth-dependent changes in rise time were larger at higher pacing rates. Modeling data qualitatively reproduced the behavior seen experimentally and demonstrated a parallel reduction in peak INa and electrotonic load as the wavefront approaches the epicardial surface. Conclusions—Decreased electrotonic load at the epicardial surface results in more rapid AP upstrokes and higher conduction velocities compared with the bulk myocardium. Combined effects of tissue depth and pacing rate on AP rise time reduce conduction safety and myocardial excitability within the ventricular wall.
Scalable Ternary Content Addressable Memory implementation using FPGAs

Ternary Content Addressable Memory (TCAM) is widely used in network infrastructure for various search functions. There has been a growing interest in implementing TCAM using reconfigurable hardware such as Field Programmable Gate Array (FPGA). Most of existing FPGA-based TCAM designs are based on brute-force implementations, which result in inefficient on-chip resource usage. As a result, existing designs support only a small TCAM size even with large FPGA devices. They also suffer from significant throughput degradation in implementing a large TCAM, mainly caused by deep priority encoding. This paper presents a scalable random access memory (RAM)-based TCAM architecture aiming for efficient implementation on state-of-the-art FPGAs. We give a formal study on RAM-based TCAM to unveil the ideas and the algorithms behind it. To conquer the timing challenge, we propose a modular architecture consisting of arrays of small-size RAM-based TCAM units. After decoupling the update logic from each unit, the modular architecture allows us to share each update engine among multiple units. This leads to resource saving. The capability of explicit range matching is also offered to avoid range-to-ternary conversion for search functions that require range matching. Implementation on a Xilinx Virtex 7 FPGA shows that our design can support a large TCAM of up to 2.4 Mbits while sustaining high throughput of 150 million packets per second. The resource usage scales linearly with the TCAM size. The architecture is configurable, allowing various performance trade-offs to be exploited. To the best of our knowledge, this is the first FPGA design that implements a TCAM larger than 1 Mbits.
An Efficient Variable Dimension PSO Algorithm for Mobile Node Tour Planning in WSN

Recent advances in unmanned aerial vehicle (UAV) and wireless charging technologies have made it practical to introduce a mobile node into Wireless Sensor Networks (WSN). This mobile node with sink ability or charging equipment on it can travel around the entire network to gather data from isolate sensor nodes or charge the nodes wirelessly. This can help with the large scale WSN to be connected or keep working for a long time without replacing batteries. For the mobile node, routing design is an important problem. We can regard this problem as a special case of traveling salesman problem with neighborhoods (TSPN), which is NP-hard. In this paper, we propose a novel routing design algorithm base on Variable Dimensions Particle Swarm Optimization (VD-PSO). In this algorithm, every particle is a feasible solution of TSPN. Every dimension of the particle is the coordinates of a rendezvous point (the point where mobile node stay to gather data or charge the nodes). And the dimensionality is right the number of the rendezvous point. With the evolutionary method of the particles, we can derive the best route of the mobile node. Simulation results show that our scheme has fast convergence speed, and the result is quite approximate to the optimal solution.
The effect of sleep deprivation on serum igg responses to aerobic activity in college student athletes

Цель : сон является восстановительным процессом для иммунной системы. Существует много ситуаций, в которых сон нарушается в т. ч. и в спортивной практике. Тем не менее, эффект депривации сна на уровень иммунных показателей в ответ на физические упражнения остается неизвестным. Целью данного исследования было изучить влияние лишения сна на уровень иммуноглобулина IgG в сыворотке при аэробной активности. Материалы и методы : В этом квазиэкспериментальном исследовании добровольно участвовали 10 студентов спортсменов (мужчины). Исследование было проведено в двух группах - контрольной и экспериментальной в течение двух недель. В контрольной группе был нормальный сон и аэробные нагрузки, а в экспериментальной - применялись аэробные нагрузки в сочетании с лишением сна. Аэробная активность проводилась на велоэргометре в течение 30 минут при интенсивности от 70 до 75 процентов от максимальной частоты сердечных сокращений. Изменения концентрации сыворотки IgG в предварительном испытании до и после аэробной активности в обоих случаях были проанализированы путем повторных измерений ANOVA и t-тестов с использованием программного обеспечения SPSS. Результаты : Результаты показали, что лишение сна не оказывает существенного влияния на показатели сыворотки IgG по отношению к аэробной активности (р = 0,130). Кроме того, аэробная нагрузка не оказывает существенного влияния на концентрации сыворотки IgG (р = 0,357). Но лишение сна вызвало значительно увеличить в концентрации иммуноглобулина IgG в сыворотке (р = 0,035). Выводы : не обнаружено существенного влияние лишения сна на концентрацию иммуноглобулина IgG в сыворотке по отношению к аэробной активности.
Effect of Lactate Treatments on Survival of Food-Borne Pathogens in Frozen Shrimp (Penaeus merguiensis)

Problem statement: Sodium lactate treatments were evaluated for reduci ng population of pathogenic bacteria such as Salmonella enteritidis , E. coli O157:H7, Vibrio parahaemolyticus and Vibrio cholerae , inoculated on frozen shrimp ( Penaeus merguiensis ). Approach: Fresh shrimp were inoculated with the above pathogens, separately, at level of 10 5 CFU g -1 and appliedin sodium lactate solutions (NaL: 0.5% and 2.5% v/v) and 1% Lactic Acid (LA) plus 1.5% sodium lactate (as buffered lactic acid) followed by freezing. The samples were stored at -18°C and antimicrobial and organoleptical effects of the treatments were evalu ated after 90 days. Results: Results indicated that there was synergistic effect between frozen storage combined with 2.5% (v/v) buffered LA which resulted in a great significant reductions (p≤0.05) approximately 5.11, 5.39, 2.86 and 2.66 log CFU g -1 in the number of colonies of V. cholerae , V. parahaemolyticus , S. enteritidis and E. coli O157:H7, respectively. On the other hand, although the effectiveness of sodium lactate increase with increased concentrations, however, there are sensor y problems associated with increasing concentrations of sodium lactate. Conclusion/Recommendations: Therefore, 1.5% (v/v) sodium lactate plus 1.0% (v/v) Lactic Acid (buffered LA) w as recommended to be used for frozen shrimps without adversely interfering with sensory quality.
Linking self and ingroup : Self-anchoring as distinctive cognitive route to social identification

The present paper investigates how cognitive projection processes instigate social identification. We complement the classical self-stereotyping approach (i.e., conforming to prototypical group norms) by investigating self-anchoring (i.e., projection from self to group) as a distinct cognitive route to social identification. Self-anchoring has mainly been investigated as predictor of intergroup differentiation. Surprisingly, no reliable link has been provided yet between self-anchoring and social identification. In Study 1, we provide first evidence for this positive link. In Study 2, we add self-stereotyping to our model and show that self-anchoring is still positively related to social identification when controlling for self-stereotyping. Additionally, we show that self-anchoring is positively related to affective components of identification, while self-stereotyping is positively related to cognitive components. Moreover, we examined the impact of self-concept stability on self-anchoring. Self-concept stability was positively related to self-anchoring, and hence to social identification (Study 1), independently from self-stereotyping (Study 2). In the discussion, we argue that disentangling self-anchoring from self-stereotyping is important as it increases our insight in how people identify, and how this may vary depending on self-concept and group context.

Effects of Classroom Embeddedness and Density on the Social Status of Aggressive and Victimized Children

This study investigated the independent and interacting effects of classroom-level embeddedness (i.e., hierarchical vs. egalitarian) and classroom density on the perceived popularity and social preference of aggressive and victimized 3rd-4th grade students (N = 881). A cohesive blocking procedure was used to compute embeddedness. Multilevel analyses indicated that aggressive children achieved much higher perceived popularity in hierarchical classrooms with high density. While children with high victimization scores were unpopular across classrooms, they were least unpopular in egalitarian classrooms with high density. Furthermore, aggressive children were more disliked in low-density classrooms, and victimized children were more disliked in hierarchical classrooms. Implications for educational management of classroom social structures are discussed.
An accurate simulation framework for thermal explorations and optimizations

While technology scaling allows to integrate more cores in the same chip, the complexity of current designs requires accurate and fast techniques to explore different trade-offs. Moreover, the increased power densities in current architectures highlight thermal issues as a first class design metric to be addressed. At the same time, the need to access to accurate models for the exploited actuators is of paramount importance, since their overheads can shadow the benefit of the proposed methodologies. This paper proposes a complete simulation framework for the assessment of run-time policies for thermal-performance and power-performance trade-offs optimization with two main improvements over the state of the art. First, it accurately models Dynamic Voltage and Frequency Scaling (DVFS) modules for both cores and NoC routers as well as a complete Globally Asynchronous Locally Synchronous (GALS) design paradigm and power gating support for crossabar and buffers in the NoC. Second, it accounts for the chip thermal dynamics as well as power and performance overheads for the actuators.
