Interference avoidance in rapidly deployed wireless ad hoc incident area networks

In [1], we investigated the use of multi-hop relays (a.k.a. breadcrumbs) to extend the range of public safety communications in indoor environments where the radio propagation conditions are harsh or wireless communications are limited by distance. In this work, we consider the impact of interference on the reliability of the breadcrumb system. We develop a simulation model for the system that considers the incident area floor plan, the characteristics of radio propagation within the incident area, emergency responders' mobility, and the distributed functionalities of the breadcrumb system. We then evaluate the performance of the breadcrumb system in the presence of interference showing that it is diminished. Consequently, we consider the use of the cognitive radio technology to enable breadcrumbs to detect interference, to identify vacant channels, and to dynamically and autonomously adapt their channel selection to enhance the system performance. We develop the functionalities of cognitive radio in our simulation, re-evaluate the system performance in the presence of interference, and show that employing cognitive radios alleviates the impact of interference. We also highlight the overhead that the cognitive radio functionalities may have under favorable network conditions.
NuSTAR DETECTION OF HARD X-RAY PHASE LAGS FROM THE ACCRETING PULSAR GS 0834−430

The Nuclear Spectroscopic Telescope Array hard X-ray telescope observed the transient Be/X-ray binary GS 0834−430 during its 2012 outburst—the first active state of this system observed in the past 19 yr. We performed timing and spectral analysis and measured the X-ray spectrum between 3–79 keV with high statistical significance. We find the phase-averaged spectrum to be consistent with that observed in many other magnetized, accreting pulsars. We fail to detect cyclotron resonance scattering features that would allow us to constrain the pulsar's magnetic field in either phase-averaged or phase-resolved spectra. Timing analysis shows a clearly detected pulse period of ∼12.29 s in all energy bands. The pulse profiles show a strong, energy-dependent hard phase lag of up to 0.3 cycles in phase, or about 4 s. Such dramatic energy-dependent lags in the pulse profile have never before been reported in high-mass X-ray binary pulsars. Previously reported lags have been significantly smaller in phase and restricted to low energies (E < 10 keV). We investigate the possible mechanisms that might produce this energy-dependent pulse phase shift. We find the most likely explanation for this effect is a complex beam geometry.
Out of Order

This article seeks to demonstrate the centrality of maintenance and repair to an understanding of modern societies and, particularly, cities. Arguing that repair and maintenance activities present a kind of 'missing link' in social theory, which is usually overlooked or forgotten, the article begins by recalling Heidegger's concept of material things as being 'ready to hand'. The main elements of practices of repair and maintenance are then elaborated on so as to help establish the argument that, by focusing on failure and breakdown in technical artefacts and systems, their vital contribution can be brought to the fore. The article then moves on to suggest that prevailing cultural constructions, and imaginations, of the 'infrastructure' that sustains modern societies, actively work to push repair and maintenance activities beyond the attention of social science. To exemplify these arguments, the article explores in detail some of the repair and maintenance activities that sustain, first, the nexus between computer communications and electricity and, second, the system of automobility. The article concludes by excavating a politics of repair and maintenance in modern cities and societies.
Relationships between psychosocial adjustment and hopelessness in women with breast cancer.

OBJECTIVE Several physical, psychological and social variables influence women with breast cancer. This study was designed to analyze the relationship between psychosocial adjustment and hopelessness in a group of such women in Turkey. METHOD The subjects were 90 women with breast cancer recruited at Ege University School of Medicine Department of Radiation Oncology Nurse Counsellor Unit and Tulay Aktas Oncology Hospital Outpatient Chemotherapy Unit. Data were collected using an Introductory Information Form and Psychosocial Adjustment to the Illness Scale - Self-Report (PAIS-SR) and the Beck Hopelessness Scale (BHS) and analyzed by Pearson Correlation Analysis. RESULTS The mean age of the women was 49.4 ± 11.0. It was found that the level of psychosocial adjustment of 63.3% of the women was 'poor'. A positive relationship was determined between PAIS-SR mean score and BHS mean score of the women with breast cancer (r = 0.731, p < 0.01). CONCLUSION It was observed that as the psychosocial adjustment worsens, as the level of hopelessness of the women increases. In the light of this relationship, it was concluded that the attempts to increase hope and therefore the support for the psychosocial adjustment of patients should play a vital role in increasing their quality of life.
Gender Differences in the Decision to Run for School Board

Proponents of the political pipeline theory argue that when more women fill the ranks of locally elected positions, the number of qualified female candidates will increase and more women will eventually be elected statewide and nationally. Given that women are elected at the school board level at higher rates than any other political office, do women run for school board in hopes of using it as a stepping stone for a larger career in politics? This article analyzes whether there are gender differences among school board members with respect to the reasons they run for office. Men are more likely than women to be motivated to run to shape education policy and for religious or moral reasons. However, relatively few school board members run with the express purpose of gaining political experience, regardless of gender.
Homolog of the maize beta-glucosidase aggregating factor from sorghum is a jacalin-related GalNAc-specific lectin but lacks protein aggregating activity.

Recently, we identified the maize beta-glucosidase aggregating factor (BGAF) as a jacalin-related lectin (JRL) and showed that its lectin domain is responsible for beta-glucosidase aggregation. By searching for BGAF homologs in sorghum, we identified and obtained an EST clone and determined its complete sequence. The predicted protein had the same modular structure as maize BGAF, shared 67% sequence identity with it, and revealed the presence of two potential carbohydrate-binding sites (GG.ATYLQ, site I and GG.GVVLD, site II). Maize BGAF1 is the only lectin from a class of modular JRLs containing an N-terminal dirigent and a C-terminal JRL domain, whose sugar specificity and beta-glucosidase aggregating activity have been studied in detail. We purified to homogeneity a BGAF homolog designated as SL (Sorghum lectin) from sorghum and expressed its recombinant version in Escherichia coli. The native protein had a molecular mass of 32 kD and was monomeric. Both native and recombinant SL-agglutinated rabbit erythrocytes, and inhibition assays indicated that SL is a GalNAc-specific lectin. Exchanging the GG.GVVLD motif in SL with that of maize BGAF1 (GG.GIAVT) had no effect on GalNAc-binding, whereas binding to Man was abolished. Substitution of Thr(293) and Gln(296) in site I to corresponding residues (Val(294) and Asp(297)) of maize BGAF1 resulted in the loss of GalNAc-binding, indicating that site I is responsible for generating GalNAc specificity in SL. Gel-shift and pull-down assays after incubating SL with maize and sorghum beta-glucosidases showed no evidence of interaction nor were any SL-protein complexes detected in sorghum tissue extracts, suggesting that the sorghum homolog does not participate in protein-protein interactions.
Doctoral supervision in a cross-cultural context: issues affecting supervisors and candidates

This article presents an analysis of rich data, gathered from interviews with 46 candidates and 38 supervisors from three Australian universities, about experiences of doctoral supervision in cross-cultural situations. Our analysis shows that many of the issues reported by international candidates are the same as those encountered by domestic candidates. However, this study has identified eight intensifiers that make such situations more complicated or difficult for candidates in a cross-cultural context: language; cultural differences in dealing with hierarchy; separation from the familiar; separation from support; other cultural differences; stereotypes; time; and what happens when the candidate returns home. The two intensifiers mentioned by more than 50% of interviewees are separation from the familiar and language. Using intensifiers as a conceptual framework for self-examination may help universities to better understand the real issues, to target resources, to mitigate distress to international candidates and reduce pressure on supervisors.
Clinical supervision of speech-language pathology students: Comparison of two models of feedback

Clinical practicum is a critical component of the education of speech-language pathologists. Various models of clinical supervision have been proposed but there have been few systematic studies comparing models. In this study, 19 speech-language pathology students were randomly assigned to two groups, one with immediate verbal feedback in a group format and the other with delayed written feedback in an individual format. Both had the same clinical supervisor and clinical placement. Student feedback on a questionnaire indicated perceived advantages and disadvantages with both supervision methods. Both groups showed significantly better performance in treatment skills, interpersonal skills and evaluation skills in an end-block evaluation than at mid-block. However, students in the immediate verbal feedback group achieved significantly higher ratings on the clinic evaluation form than students in the delayed written feedback group. Students in the immediate verbal feedback group also scored higher on a self-rated questionnaire modified from Motivated Strategies for Learning Questionnaire (MSLQ) than those in the other group, both in the first and last clinical sessions. Further directions for studies of clinical supervision and clinical education are identified.
Family network of children with special health needs: implications for nursing.

OBJECTIVE to describe appropriate sources and resources for caregivers of children with special health needs in the community. METHOD A qualitative study that used the creativity and sensitivity dynamics speaking map, part of the sensitive creative method, involving 11 caregivers of children with special health needs who are assisted in a university hospital located in the South of Brazil. RESULTS the maps graphically represented through the genogram and ecomap showed that the caregiving women consistently and regularly use the resources of the internal and external family network; they eventually and irregularly access the community social network for physical and psychological support. CONCLUSION the reclusive nature of care for these children inside the family circle contributes to their social invisibility. Based on this new information, it is recommended that Nursing participate in the care that is focused on these children's families, with particular attention to their socio-cultural conditions.
Personality style, psychological adaptation and expectations of trainee clinical psychologists

The literature suggests that personality affects how individuals experience stress, cope, utilize social support and psychologically adapt. This study examined the personality style, psychological adaptation and expectations of 364 UK trainee clinical psychologists. Personality traits characterizing the sample were: enhancing, modifying, extraversing, outgoing, and agreeing. Mean overall personality adjustment was significantly better than the normal population. The sample scored significantly poorer on self-esteem, anxiety and depression, but well outside the defined range for poor adaptation. A small percentage (8%, n = 31) had ‘poor’ personality adjustment scores, scored worse on indicators of psychological adaptation and reported greater shortfall of course aspects compared with expectations. However, 41% scored as having a significant problem on one or more of: anxiety, depression, low self-esteem and work adjustment. About one-third had a probable substance use problem. In regression analyses, poor personality adjustment, and different areas of expectation-shortfall, especially impact of training on life variously predicted anxiety, depression, and poor work adjustment. Satisfaction with social support was not predictive of adaptation after personality adjustment was accounted for. Implications for clinical psychology training include the need for enhanced expectation-management through pre-course marketing, and better attention to trainees' personal and professional development throughout training.

‘No Bleeding, Whining Minnies’: Some Perspectives on the Role of YTS in Class and Gender Reproduction

Abstract This paper is about social class, gender, the Youth Training Scheme and social reproduction, which are explored in the context of entry into ‘caring’ careers. The data is drawn from one of a group of ethnographic studies being undertaken within the context of the ESRC 16‐19 Initiative. This particular study is based on participant observation with a group of 16 to 18 year old girls training for jobs in the field of institutional care. The paper begins by exploring aspects of the girls’ experience of their training and work placements. These involve physically and emotionally stressful tasks such as coping with violence, dealing with incontinence and laying out the dead. The paper then documents a gradual process of adjustment to this type of work which ends with the girls positively seeking work in this field. This provides a basis for posing the central questions of the paper: why do working‐class girls continue to enter working‐class, gender‐stereotyped jobs? What roles does the Youth Training .
The Dwarf Spheroidal Companions to M31: Variable Stars in Andromeda I and Andromeda III

We present the results of variable star searches of the M31 dwarf spheroidal (dSph) companions Andromeda I and Andromeda III using the Hubble Space Telescope. A total of 100 variable stars were found in And I, while 56 were found in And III. One variable found in And I and another in And III may be type II Cepheids. In addition to this variable in And III, another four variables are anomalous Cepheids (ACs). So far, no definite ACs have been discovered in And I. We discuss the properties of these variables with respect to those found in the other dSph galaxies and revisit the AC period-luminosity relations. We found 72 fundamental mode RR Lyrae (RRab) stars and 26 first-overtone mode RR Lyrae (RRc) stars in And I giving mean periods of 0.575 and 0.388 days, respectively. One likely RR Lyrae star in And I remains unclassified because of a lack of F555W data. For And III, 39 RR Lyrae stars are pulsating in the fundamental mode with a mean period of 0.657 days, and 12 are in the first-overtone mode with a mean period of 0.402 days. Using the mean metal abundances derived from the red giant branch colors, the mean RRab period for And I is consistent with the mean period-metallicity relation seen in the RR Lyrae populations of Galactic globular clusters, while And III is not, having too large a mean RRab period for its abundance. In And I, we found two RR Lyrae stars that are noticeably fainter than the horizontal branch. We discuss the possibility that these stars are associated with the recently discovered stellar stream in the halo of M31. Using various methods, we estimate the mean metallicity of the RR Lyrae stars to be ⟨[Fe/H]⟩ ≈ -1.5 for And I and ≈-1.8 for And III. These estimates match well with other mean metallicity estimates for the galaxies. Interestingly, a comparison of the period-amplitude diagrams for these two galaxies with other dSph galaxies shows that And III is lacking in shorter period, higher amplitude RR Lyrae stars. This may be a consequence of the very red horizontal branch morphology in this dSph. Not including the two faint RR Lyrae stars, we find ⟨VRR⟩ = 25.14 ± 0.04 mag for And I, resulting in a distance of 765 ± 25 kpc. For And III, ⟨VRR⟩ = 25.01 ± 0.04 mag, giving a distance of 740 ± 20 kpc. These distance estimates are consistent with those previously found for these galaxies. We discuss the relation between the specific frequency of the ACs in dSph galaxies and the mean metallicity of the galaxy, finding that the M31 dSph galaxies follow the same relations as the Galactic dSph galaxies. We also find that the period-luminosity relations of ACs and short-period Cepheids are distinct, with the short-period Cepheids having higher luminosities at a given period.
Cutud's Ritual of Nailing on the Cross: Performance of Pain and Suffering

This research investigates the ritual nailing on the cross every Good Friday in Cutud, Pampanga, in the Philippines as a local religiocultural performance. It highlights the ritual's evolution and historicity of suffering in the context of panata (religious pledge/ vow), as a characteristic central to the Filipino people since precolonial times. The roots of the ritual can be traced from pamagdarame (flagellation) and the sinakulo (passion play) written by Ricardo Navarro in 1955. Devotees (participants) of pamagdarame and the sinakulo are participating with intentions of panata. The ritual, manifested through a performance of pain and suffering, allows the devotee's inner core (kalooban) via his sacrifice to be one with the Supreme Being. The ritual, which has developed into a multifaceted tradition, is not only a religious occasion (an experience of a personal sacrifice or panata for the individual) but also a social drama (an expression of pain and suffering through the performance of Via Crucis o Pasion Y Muerte [Way of the Cross or Passion and Death] and the nailing on the cross performed for the good of others).
Arousal of Flow Experience in a Learning Setting and Its Effects on Exam Performance and Affect

Flow experience is associated with learning motivation, performance and positive affect. Therefore it is important to analyze its antecedents. An important antecedent for experiencing flow is the balance between the person's skill and how challenging the situation is (Csikszentmihalyi, 1990). According to Atkinson's (1957) risk-taking model, only individuals with high hope-of-success prefer situ- ations in which a balance of challenge and skill is given while individuals with high fear-of-failure try to avoid such situations. Integration of these two lines of research leads to the suggestion that the achievement motive might moderate the relationship between the challenge- skill balance and flow experience. This notion could be confirmed in two studies with undergraduate students (N = 57/N = 395). Addi- tionally, flow experience was found to be a significant predictor of affect (Study 1 and 2) and exam performance (Study 2). I discuss these findings and their practical implications for academic learning settings.
A public policy perspective on English medium instruction in China

Abstract Language education for ethnic majority and minority students alike has recently received much policy attention in the People's Republic of China. An outcome of this policy attention is the Chinese–English bilingual education initiative which turns on the use of English as a medium of instruction for Han majority students at the primary and secondary levels of education. This paper draws on the public policy perspective on language policy formulated by François Grin and analyses the English medium instruction initiative in terms of four principles that can guide policy evaluations, namely normative justification, practical feasibility, allocative effectiveness and distributive justice. Implications then are derived from the analysis for a policy deliberation on the use of English as an instructional medium in trilingual provision for autochthonous ethnic minorities in China. The paper concludes by sketching a policy alternative to English medium instruction for both majority and minority students.
The 'Early' Morgenthau. A Comment on the Intellectual Origins of Realism

Hans J. Morgenthau is the most important representative of the 'realist' school in the discipline of international politics. It seems, however, to have been forgotten that before his departure to the United States in 1937 he had written several books and articles on international law and on the relations between law and politics. An analysis of Morgenthau's 'European' writings demonstrates, in the first place, that important elements of his post-war 'realist' thoughts on international politics are found in his pre-war writings and, secondly, that these thoughts were by no means new nor surprising to contemporary European scholars. In conclusion, it is suggested that the intellectual origins of 'realism' are not to be found in the American debate between 'utopians' and 'realists', but in a much older and quite established European academic tradition.
Gender Differences in Dissociation

Considering that epidemiological research on dissociative disorders has suggested a 9 to 1 predominance of female cases, this study investigated the relationship between gender and dissociation using a dimensional approach. A total of 2,153 participants from different diagnostic groups completed the Dissociative Experience Scale. In order to control for the confounding effect of current psychopathology a subgroup 790 subjects additionally completed the SCL-90. We did not find any differences in the general or pathological dissociation scores. Hypothetical gender differences in dissociative psychopathology were not a function of diagnostic categories. There were no significant sex differences in the distribution of high dissociators. Our findings suggest that men and women do not generally differ in dissociative psychopathology. The implications for future investigations on the epidemiology, etiology, and psychobiology of dissociative symptoms are discussed.
My boss' group is my group: experimental evidence for the leader‐follower identity transfer

Purpose – The purpose of this paper is to extend work on the leader‐follower identity transfer by providing the first empirical evidence for the causal relationship between leader and follower organizational identification.Design/methodology/approach – The proposed causal relationship between leader and follower organizational identification (OI) was tested in a scenario study and in a laboratory experiment. Additionally, in the laboratory experiment the impact of leader OI on follower performance was examined.Findings – The results suggest that highly identified leaders positively influence their followers' attitudes and performance by affecting their self‐concept, i.e. increasing their OI.Practical implications – Improving leader OI provides a promising way for organizations to increase their employees' OI and performance.Originality/value – The paper provides the first empirical evidence for the proposed causal relationship between leader and follower OI, with implications for individual and organizati.
