A traffic aware, energy efficient MAC protocol for wireless sensor networks

In this paper, we focus on the problem of designing an energy efficient MAC protocol for wireless sensor networks and propose a novel scheme, named TEEM (traffic aware, energy efficient MAC). Inspired by the S-MAC protocol, probably the most well-known sensor MAC scheme for energy efficiency, the proposed TEEM is also based on the concept of 'listen/sleep modes cycle'. However, unlike S-MAC where the duration of listen and sleep modes are fixed, our TEEM protocol makes these durations adaptive by utilizing the 'traffic information' of each node, and hence achieves a significant decrease in power consumption. Through implementation in motes sensors, the presented TEEM is evaluated and compared to S-MAC as well as the IEEE 802.11-like protocols.
Barrientosiimonas endolithica sp. nov., isolated from pebbles, reclassification of the only species of the genus Tamlicoccus, Tamlicoccus marinus Lee 2013, as Barrientosiimonas marina comb. nov. and emended description of the genus Barrientosiimonas.

Strain JC268(T) was isolated from pebbles collected from a dam located in Lalitpur, Uttar Pradesh, India. Cells of strain JC268(T) were coccoid, appeared in pairs/triads/tetrads or short chains and were Gram-stain-positive, non-spore-forming, non-motile and obligately aerobic. Strain JC268(T) was catalase- and oxidase-positive and utilized citrate for growth. The genomic DNA G+C content of strain JC268(T) was 65.3 mol%. The cell-wall peptidoglycan contained L-lysine-L-serine-D-aspartic acid as interpeptide bridge with the type A4α. The major menaquinone was MK-8(H4). Major (>10%) fatty acids were iso-C16 : 0, iso-C16 : 1H and anteiso-C17 : 1ω9c. Diphosphatidylglycerol, phosphoglycolipid, phosphatidylinositol, glycolipid, four unidentified lipids, an amino lipid and phospholipid were the polar lipids of strain JC268(T). EzTaxon-e blast search of 16S rRNA gene sequences showed that strain JC268(T) has highest similarity to Barrientosiimonas humi 39(T) (98.65%) and Tamlicoccus marinus MSW-24(T) (97.8%) of the family Dermacoccaceae. Genome reassociation (based on DNA-DNA hybridization) of strain JC268(T) with Barrientosiimonas humi CGMCC 4.6864(T) ( = 39(T)) and T. marinus KCTC 19485(T) ( = MSW-24(T)) yielded values of 32.5 ± 2% and 27.3 ± 2%, respectively. Based on the data from phylogenetic and polyphasic taxonomic analyses, strain JC268(T) represents a novel species of the genus Barrientosiimonas for which the name Barrientosiimonas endolithica sp. nov., is proposed. The type strain of Barrientosiimonas endolithica is JC268(T) ( = KCTC 29672(T) = NBRC 110608(T)). Our data suggest that T. marinus should be reclassified within the genus Barrientosiimonas. Thus, a reclassification is proposed for T. marinus, the type and only species of the genus Tamlicoccus, as Barrientosiimonas marina comb. nov., which implies the emendation of the description of the genus Barrientosiimonas.
The Economist's Oath: On the Need for and Content of Professional Economic Ethics

Economists enjoy enormous influence over the life chances of the world's inhabitants, yet do not receive, at any point in their training, any exposure to the professional ethical challenges that their work entails. This lack of attention to professional ethics means that even well-meaning economists will take actions that can cross ethical lines, to the detriment of those whom they seek to serve. The Economist's Oath seeks to initiate a serious conversation among economists about the ethical content of their work, by raising fundamental questions on the nature of what economists do, the reception that ethics has historically had in the profession and why, how this reception is dangerous for all parties involved, the lessons to be drawn from other professions with advanced professional ethics, the principles that could emerge from professional economics ethics, and the kinds of reform in economic education that might be implied by a commitment to professional ethics. The book does not present an ethical expose or seek to embarrass the profession or individual economists, nor does it seek to lay down an ethical law for the profession. Instead, it more modestly but more importantly advances the case for the inauguration of a new tradition of inquiry. DeMartino argues that critical inquiry by economists into professional economic ethics would enhance the quality of the services that the profession offers, might help to prevent avoidable and consequential errors and could provide the communities that economists serve with a standard to which economists could be held accountable.

Emotion and the Prefrontal Cortex: An Integrative Review

The prefrontal cortex (PFC) plays a critical role in the generation and regulation of emotion. However, we lack an integrative framework for understanding how different emotion-related functions are organized across the entire expanse of the PFC, as prior reviews have generally focused on specific emotional processes (e.g., decision making) or specific anatomical regions (e.g., orbitofrontal cortex). Additionally, psychological theories and neuroscientific investigations have proceeded largely independently because of the lack of a common framework. Here, we provide a comprehensive review of functional neuroimaging, electrophysiological, lesion, and structural connectivity studies on the emotion-related functions of 8 subregions spanning the entire PFC. We introduce the appraisal-by-content model, which provides a new framework for integrating the diverse range of empirical findings. Within this framework, appraisal serves as a unifying principle for understanding the PFC’s role in emotion, while relative content-specialization serves as a differentiating principle for understanding the role of each subregion. A synthesis of data from affective, social, and cognitive neuroscience studies suggests that different PFC subregions are preferentially involved in assigning value to specific types of inputs: exteroceptive sensations, episodic memories and imagined future events, viscero-sensory signals, viscero-motor signals, actions, others’ mental states (e.g., intentions), self-related information, and ongoing emotions. We discuss the implications of this integrative framework for understanding emotion regulation, value-based decision making, emotional salience, and refining theoretical models of emotion. This framework provides a unified understanding of how emotional processes are organized across PFC subregions and generates new hypotheses about the mechanisms underlying adaptive and maladaptive emotional functioning.
Gender differences in work–home interplay and symptom perception among Swedish white-collar employees

Objective: To analyse gender differences in paid and unpaid workload and symptoms in matched groups of Swedish white-collar workers with children. Design and setting: Paid and unpaid workload and perceived stress from paid work, conflict between demands and control over household work were measured by a total workload (TWL) questionnaire. Some symptoms were rated with regard to frequency and severity as a measure of health. Cross-sectional analyses were performed. Participants: Matched groups of male (n = 440) and female (n = 529) well-educated white-collar workers in full-time employment, aged 32–58 years and living with children in the home. Results: Women in higher positions in Sweden are healthier than the average population of women, but report more symptoms than men in the same position as well as more stress from paid work, more conflict between demands and a greater TWL. However, women also reported more control over household duties and TWL was not associated with more symptoms. The men were mainly focused on their paid work role and perhaps even more so than men in the general population as they were fairly resistant to feelings of conflicting demands. Conclusion: Even among matched groups of full-time employed, well-educated men and women, traditional gender differences in division of responsibilities and time allocation were found. Even though the women were healthy at this stage, they might risk future ill health, owing to high workload, stress and feelings of conflicting demands.
Stability, Survival, and Tolerability of an Auditory Osseointegrated Implant for Bone Conduction Hearing: Long-Term Follow-Up of a Randomized Controlled Trial

Objective: To compare implant stability, survival, and soft tissue reactions for a novel (test) and previous generation (control) percutaneous auditory osseointegrated implant for bone conduction hearing at long-term follow-up of 5 years. Study Design: Single follow-up visit of a previously completed multicenter, randomized, controlled trial. Patients: Fifty-seven of the 77 participants of a completed randomized controlled trial on a new auditory osseointegrated implant underwent a single follow-up visit 5 years after implantation, which comprised implant stability measurements and collection of Holgers scores. Additionally, implant survival was recorded for all 77 patients from the original trial. Results: The test implant showed significantly higher implant stability quotient (ISQ) values compared with the control implant throughout the 5-year follow-up. Mean area under the curve of ISQ high from baseline to 5 years was 71.6 (standard deviation [SD] ±2.0) and 66.7 (SD ±3.4) for the test and control implant, respectively (p < 0.0001). For both implants, the mean ISQ value recorded at 5 years was higher compared with implantation (test group +2.03 [SD ±2.55, within group p < 0.0001] and control group +2.25 [SD ±4.95, within group p = 0.12]). No difference was noticed in increase from baseline between groups (p = 0.64). Furthermore, evaluation of soft tissue reactions continued to show superiority of the test implant. At the 5-year follow-up visit, one patient (2.5%) presented with a Holgers grade 2 in the test group, compared with four patients (23.5%) in the control group (p = 0.048); no patient presented with more severe soft tissue reactions. Excluding explantations, the survival rate was 95.8% for the test group and 95.0% for the control group. The corresponding rates including explantations were 93.9 and 90.0%. Conclusion: The test implant showed superiority in terms of higher mean ISQ values and less adverse soft tissue reactions, both at the single 5-year follow-up visit and during the complete follow-up. In addition, both implants showed an equally high implant survival.
eMood: Modeling Emotion for Social Media Analytics on Ebola Disease Outbreak

Social media enable users to express their emotion promptly, helping health policy makers to gauge public sentiment of disease outbreak. In this research, we developed an approach to social-media-based public health informatics and built a proof-of-concept system named eMood that helps to collect, analyze, and visualize Ebola outbreak discussions on Twitter. Our approach uses a comprehensive lexicon to identify emotion categories and present analysis findings of users’ network relationship and influence patterns. We compared two methods of identifying user influence, user centrality and emotion entrainment, by using 255,118 tweets posted by 210,900 users in January 2015. Experimental results show that both methods identified highly influential users. Regression analysis of user influence rank and emotion scores demonstrates significant relationship between user influence and each emotion category. These results should provide strong implication for understanding social actions and for collecting social intelligence for public health informatics.
On The Relation Between Memory And Metamemory In Free Recall: The Effects Of List Length And Word Frequency On Dual Processes

Subjective judgments about retrieval phenomenologies (remember/know) and memory strength (confidence) are often used in dual-process research to separate recollective from nonrecollective retrieval. Although such methods provide process-level explanations of the effects of list length and word frequency on recognition, whether the same applies to free recall is unknown. I compared subjective and objective methods of measuring dual processes and investigated their process-level explanations of the effects of list length and word frequency on free recall. Ninetyfive undergraduates received multiple study-test trials and made retrospective judgments about items recalled on the last trial. A dual-retrieval Markov chain was used to quantify recollective and nonrecollective retrieval from subjects’ recall performance rather than their metacognitive judgments to recalled items. In free recall, list length affected both recollective and nonrecollective retrieval, whereas word frequency only affected recollective retrieval. In addition, although remember judgments and correct source identification correlated with an objective measure of recollective retrieval (direct access), high confidence did not and it was unrelated to memory strength in free recall.
Preservice Teachers Planning for Critical Literacy Teaching

This case reflects a yearlong project I, as the instructor of an Advanced Methods course, conducted with my students to help them plan and implement critical literacy units in their high school and middle school student teaching placements. To do so, I assigned student teachers to explore notions of critical literacy (including resistant reading, marginalized perspectives, and social action projects) and then use these methods to create and teach critical literacy units over two semesters. Students then uploaded these units, along with their reflections, to electronic portfolios. This research explores how these student teachers defined critical literacy for themselves and then planned, implemented, and reflected on their units.
Inside the Black Box of the Corporate Staff: Social Networks and the Implementation of Corporate Strategy

In multidivisional firms, the corporate staff is central to the implementation of corporate-level strategy, but empirical evidence on its function is limited. We examine one corporate staff through e-mail analysis. We find sharp cross-sectional differences in communication patterns: staff members have networks that are larger, more integrative, and richer in structural holes. However, much of this difference is attributed to sorting processes, rather than being caused by employment in the corporate staff per se. Further, once people receive the ‘corporate imprimatur,’ they retain aspects of it even when they move back to the line organization. These results imply that the literature's emphasis on structure as a means to achieve coordination undervalues a selection process in which individuals with broad networks match to coordination-focused jobs in the corporate staff.

Watching the pain of others: audience discourses of distant suffering in Greece

This thesis explores the moral implications of watching suffering on the media. In particular, it addresses the question of how audiences construct their moral agency vis-a-vis the suffering of distant others they witness through television news. Theoretically, the thesis takes as a point of departure the concept of mediation as media practices. Based on an underlying assumption of moral agency as discursively constructed and articulated, I have drawn an analytical framework which employs the discursive practices of media witnessing and media remembering to explore the ways audiences talk about distant suffering and position themselves in relation to it. The thesis is empirically grounded in the context of Greece and based on focus group discussions with members of the Greek audience. The empirical analysis indicates that viewers engage with distant suffering in a multiplicity of ways that are not exhausted in feelings of empathy or compassion and their diametric opposites of apathy and compassion fatigue. These forms of engagement are filtered through both the nature and extent of media reports of suffering, and discourses about power and politics entrenched within the national culture. In this context, the analysis demonstrates that viewers position themselves as witnesses vis-a-vis news reports of distant suffering in four different modes, which are described as “affective”, “ecstatic”, “politicised” and “detached” witnessing. The exploration of the practice of media remembering illustrates the construction of a moral hierarchy in the way viewers remember distant suffering, where some events are constructed as banal and others become landmarks in audience memory. Finally, the viewers’ positioning as public actors with regard to media stories of human pain is shown to be, on the one hand, conditional upon the media staging of humanitarian appeals, and, on the other hand, embedded within and limited by frameworks of understanding civic participation in public life. The thesis contributes to a growing body of literature on the mediation of distant suffering. It especially addresses the largely neglected empirical question of audience engagement with media stories of human pain, offering both empirical evidence and an analytical framework for the study of this engagement.
Adaptive GNSS Carrier Tracking Under Ionospheric Scintillation: Estimation vs. Mitigation

This letter deals with carrier synchronization in Global Navigation Satellite Systems. The main goals are to design robust methods and to obtain accurate phase estimates under ionospheric scintillation conditions, being of paramount importance in safety critical applications and advanced receivers. Within this framework, the estimation versus mitigation paradigm is discussed together with a new adaptive Kalman filter-based carrier phase synchronization architecture that copes with signals corrupted by ionospheric scintillation. A key point is to model the time-varying correlated scintillation phase as an AR(p) process, which can be embedded into the filter formulation, avoiding possible loss of lock due to scintillation. Simulation results are provided to show the enhanced robustness and improved accuracy with respect to state-of-the-art techniques.
Learning by Doing and Learning by Thinking: An fMRI Study of Combining Motor and Mental Training

The current study investigated behavioral and neural effects of motor, mental, and combined motor and mental training on a finger tapping task. The motor or mental training groups trained on a finger-sequence for a total of 72 min over 6 weeks. The motor and mental training group received 72 min motor training and in addition 72 min mental training. Results showed that all groups increased their tapping performance significantly on the trained sequence. After training functional magnetic resonance imaging (fMRI) data was collected and indicated training specific increases in ventral pre-motor cortex following motor training, and in fusiform gyrus following mental training. Combined motor and mental training activated both the motor and the visual regions. In addition, motor and mental training showed a significant increase in tapping performance on an untrained sequence (transfer). fMRI scanning indicated that the transfer effect involved the cerebellum. Conclusions were that combined motor and mental training recruited both motor and visual systems, and that combined motor and mental training improves motor flexibility via connections from both motor and cognitive systems to the cerebellum.
Growth Response of Clarias Gariepinus Fingerlings To Different Dietary Protein Levels Of Toadmeal Inclusion

A ten-week nutritional study was carried out to evaluate the practical replacement of fishmeal with toad meal in different protein levels in the diet of Clarias gariepinus fingerlings. One hundred and fifty (150) fingerlings with an average weight of 7.99 - 27.64g were stocked at the rate of ten (10) fish per experimental tank. The fingerlings were subjected to five different dietary feeds with varying levels of toad meal at 0%, 25%, 50%, 75%, and 100% respectively. Each treatment was replicated thrice. Feeding was done at 3% body weight per day and records of weekly weight increase were kept. The feed conversion ratio, weight gain, survival rate revealed that the control (0% toadmeal inclusion) and diet 5 (100% toadmeal inclusion) were best in growth performance, unlike the mixed fishmeal and toadmeal that showed adequate growth performance. Water quality parameters of the experiment measured constantly were within the normal optimum requirements that had no negative effects on the experimental fish. Finally based on biological and financial evaluation of the feeding trials diet 5 (100%) was recommended as the most economical and practically acceptable for large-scale intensive fish culture.
Prenatal expressions of hyperpolarization-activated cyclic-nucleotide-gated channel (HCN) genes in dysplastic hippocampi in rats.

AIM Hyperpolarization-activated cyclic nucleotide-gated (HCN or h-channel) channels mediate hyperpolarization-activating currents in the hippocampus and neocortex. The aim of this study is to present prenatal h-channel gene expressions (HCN1 and HCN2; HCN1-Entrez-Gene ID: 84390; HCN2- Entrez Gene ID: 114244) in dysplastic hippocampal pyramidal neurons induced by in utero irradiation in rats. MATERIALS AND METHODS Time-pregnant Wistar albino rats were irradiated and the dysplastic hippocampus in their 2 month-old litters was studied. Gene expression was studied by RNA extraction and polymerase chain reaction methods. RESULTS None of the rats showed seizure activity. mRNA levels of HCN1 and HCN2 genes were decreased especially in the CA1 and CA3 pyramidal neurons in the hippocampi of experimental rats; however, the differences were not significant compared to controls. In CA2, mRNA levels of both genes were increased and this rise did not reach significant level. The CA4 sub-region showed a different pattern of expression: HCN1 increased but HCN2 decreased insignificantly compared to controls. CONCLUSION Our results demonstrated that dysplastic neurons showed decreased levels of mRNA expression of HCN1 and HCN2 genes, in particularly CA1 and CA3 pyramidal neurons. The rationale for how these changes contribute to epileptogenesis in dysplastic tissues still requires further studies.
