The Role of Mobile Phones in Romantic Relationships

Dr. Licoppe (Liccope, 2004) at Telecom ParisTech, Dr. Haddon (Haddon, 2003) at the London School of Economics & Political Science, and Drs. Katz and Aakhus (Katz & Aakhus, 2002) at Rutgers University are among the earliest scholars examining the role of cell phones in relationships. Dr. Ling (Ling, 2012) at IT University of Copenhagen, Dr. Rettie (Rettie, 2009) at Kingston University London, Dr. Gershon (Gershon, 2010) at Indiana University, and Drs. Robert Duran and Lynne Kelly (Duran, Kelly, & Rotaru, 2011) at the University of Hartford are among the leading experts in the area of the impact that cell phones have on romantic relationships. Just as cell phones, along with other Information Communication Technologies (ICTs), have become essential to relationship maintenance in friendship and family relationships (Tong & Walther, 2011), so too have they emerged as “key actors in the life of many American couples. They negotiate over when to use it and when to abstain” (Lenhart & Duggan, Feb. 11, 2014). Romantic partners often feel closer because of frequent texting throughout the day (Pettigrew, 2009) and they sometimes experience tension or conflict over cell phone-related issues (Duran et al., 2011; Lasén, 2011). Cell phones have taken on importance in the initiation of romance (Byrne & Findlay, 2004; Rettie, 2009) and may play a role in the dissolution of relationships (Gershon, 2010). The focus of this chapter is on the role of cell phones in romantic relationships, from initial attraction to long-term committed arrangements including marriage and cohabitation. Romantic relationships are significant in people’s lives and to their psychological and emotional well-being (Caron, Lafontaine, Bureau, Levesque, & Johnson, 2012; Gordon, Heimberg, Montesi, & Fauber, 2012). It is no wonder, then, that scholars have taken an interest in communication technologies, like the cell phone, that have the potential to enhance and disrupt these relationships in substantial ways.

Institutionalized Barriers and Supports of Female Athletic Directors: A Multilevel Perspective

Despite an increase in participation rates among girls and women across all levels of sport, women are still underrepresented in leadership positions. Less than 10% of National Collegiate Athletic Association (NCAA) Division I Athletic Directors (ADs) are female. The current study examined the supports and barriers of 10 NCAA Division I female ADs. Using institutional theory to frame the research, through semistructured interviews barriers and supports were categorized using a multilevel approach model (i.e., macro, meso, and micro). The multilevel approach allows readers to see how factors shape and are shaped by one another. Results revealed macro factors such as power, hegemonic masculinity, inclusive environments, stakeholder expectations, and institutional gender discrimination. Meso factors included occupational segregation, family-work life, organizational demography and culture. Micro factors included self-efficacy, gender socialization, career intentions, self-limiting behaviors, human and social.
Transformational and Transactional Leadership Styles of Nurse Managers and Job Satisfaction among Filipino Nurses: A Pilot Study

Background : Due to the paucity of literature in leadership styles and job satisfaction within the Philippine context, this descriptive correlational study among Filipino nurses (FNs) was piloted in a selected tertiary hospital in Manila. Purpose : This study utilized a descriptive correlational research design to describe aspects of a situation and explore relationships among leadership styles and job satisfaction, without seeking to establish causal connections Methods : Before the data collection, the researchers secured an administrative and ethical clearance from the executive assistant to the President thru the Officer-in-Charge of the Nursing Service Division of the hospital. There were 285 staff nurses, of which only 100 nurses were qualified to have at least one year of experience. Three sets of questionnaires were disseminated, and responses were treated analyzed using the descriptive statistics to describe the demographic and work profile, LS, and JS while Pearson R correlation was used to measure the relationship between LS and JS. Results : Using self-administered questionnaires, FNs rated their level of satisfaction (M=3.37) from high to a moderate extent along with professional autonomy (M=3.91), work environment (M=3.81), work assignment (M=3.61), and benefits (M=2.71). Participants agreed that their nurse managers utilized either transformational or transactional leadership styles. Findings indicate that transformational ( r =0.558, p <0.000) and transactional ( r =0.528, p < 0.000) leadership styles of nurse managers were correlated to nurses’ job satisfaction. Conclusion : The finding explicates that FNs were satisfied in their professional autonomy, work environment, and work assignment but moderately satisfied in work benefits which were also apparent in the global literature. Furthermore, the results indicate that leadership styles are related to the overall job satisfaction of among nurses.
Evaluating game preference using the fun toolkit across cultures

Over the past decade many new evaluation methods have emerged for evaluating user experience with children, but the results of these studies have tended to be reported in isolation and cultural implications have been largely ignored. This paper reports on a comparative analysis of the Fun Toolkit and the effect of culture on game preference. In total 37 children aged between 7 and 9 participated in the study, from a school in the UK and Jordan. The children played 2 different games on a tablet PC and their experiences of each were captured using the Fun Toolkit. The results showed that culture did not appear to affect children's preference and Fun Toolkit is a valid user experience tool across cultures.
SOCIAL MEDIA USE, BODY IMAGE, AND BODY WEIGHT STATUS: COMPARISON BETWEEN UNIVERSITY STUDENTS WITH AND WITHOUT DISORDERED EATING IN UNIVERSITI PUTRA MALAYSIA

ABSTRACT Background: Disordered eating, body dissatisfaction, and social media use are increasingly common among university students. This cross-sectional study aimed to compare social media use, body image, and body weight status between disordered eating (DE) and non-disordered eating (NDE) university students. Materials and Methods: There were two phases of data collection. In Phase I, a total of 505 university students (22.6% males and 77.4% females) with a mean age of 21.26 ± 1.41 years from three randomly selected faculties in UPM were screened for disordered eating using the Eating Attitude Test (EAT-26). Sociodemographic background and anthropometric measurements including weight, height, waist circumference, and body fat percentage of respondents were measured. In Phase II, those respondents with DE were matched with those without DE by sex, age, and ethnicity. They answered an online survey on body image and social media use. Result: Out of 505 university students in Phase I, 21.8% were engaged in DE with no sex difference observed ( χ 2 =0.738, p =0.390). In Phase II, 106 DE respondents were matched with 106 NDE respondents. No significant differences were found in body image, social media use (duration, volume, frequency, engagement, selfie sharing, photo investment, and photo manipulation) and body weight status between DE and NDE groups. However, DE respondents reported to have a significantly higher frequency of selfie-taking as compared to NDE respondents ( t =-2.338, p =0.020). Conclusion: High prevalence of disordered eating was observed in this study. The contribution of social media use to disordered eating needs to be further studied.

High Performance Set of Features for Human Action Classification

The most common method for handling human action classification is to determine a common set of optimal features and then apply a machine-learning algorithm to classify them. In this paper we explore combining sets of different features for training an ensemble using random subspace with a set of support vector machines. We propose two novel descriptors for this task domain: one based on Gabor filters and the other based on local binary patterns (LBPs). We then combine these two sets of features with the histogram of gradients. We obtain an accuracy of 97.8% using the 10-class Weizmann dataset and a 100% accuracy rate using the 9-class Weizmann dataset. These results are comparable with the state of the art. By combining sets of relatively simple descriptors it is possible to obtain results comparable to using more sophisticated approaches. Our simpler approach, however, offers the advantage of being less computationally expensive.
Preparation of Uniform-Sized and Dual Stimuli-Responsive Microspheres of Poly(N-Isopropylacrylamide)/Poly(Acrylic acid) with Semi-IPN Structure by One-Step Method

A novel strategy was developed to synthesize uniform semi-interpenetrating polymer network (semi-IPN) microspheres by premix membrane emulsification combined with one-step polymerization. Synthesized poly(acrylic acid) (PAAc) polymer chains were added prior to the inner water phase, which contained N-isopropylacrylamide (NIPAM) monomer, N,N′-methylene bisacrylamide (MBA) cross-linker, and ammonium persulfate (APS) initiator. The mixtures were pressed through a microporous membrane to form a uniform water-in-oil emulsion. By crosslinking the NIPAM in a PAAc-containing solution, microspheres with temperature- and pH-responsive properties were fabricated. The semi-IPN structure and morphology of the microspheres were confirmed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The average diameter of the obtained microspheres was approximately 6.5 μm, with Span values of less than 1. Stimuli-responsive behaviors of the microspheres were studied by the cloud-point method. The results demonstrated that semi-IPN microspheres could respond independently to both pH and temperature changes. After storing in a PBS solution (pH 7.0) at 4 °C for 6 months, the semi-IPN microspheres remained stable without a change in morphology or particle size. This study demonstrated a promising method for controlling the synthesis of semi-IPN structure microspheres with a uniform size and multiple functionalities.
The impact of physical activity and fitness on academic achievement and cognitive performance in children

The potential for physical activity and fitness to improve cognitive function, learning and academic achievement in children has received attention by researchers and policy makers. This paper reports a systematic approach to identification, analysis and review of published studies up to early 2009. A three-step search method was adopted to identify studies that used measures of physical activity or fitness to assess either degree of association with or effect on a) academic achievement and b) cognitive performance. A total of 18 studies including one randomised control trial, six quasi-experimental and 11 correlational studies were included for data extraction. No studies meeting criteria that examined the links between physical activity and cognitive function were found. Weak positive associations were found between both physical activity and fitness and academic achievement and fitness and elements of cognitive function, but this was not supported by intervention studies. There is insufficient evidence to conclude that additional physical education time increases academic achievement; however there is no evidence that it is detrimental. The quality and depth of the evidence base is limited. Further research with rigour beyond correlational studies is essential.
SayWAT: Augmenting Face-to-Face Conversations for Adults with Autism

During face-to-face conversations, adults with autism frequently use atypical rhythms and sounds in their speech (prosody), which can result in misunderstandings and miscommunication. SayWAT is a Wearable Assistive Technology that provides feedback to wearers about their prosody during face-to-face conversations. In this paper, we describe the design process that led to five design guidelines that governed the development of SayWAT and present results from two studies involving our prototype solution. Our results indicate that wearable assistive technologies can automatically detect atypical prosody and deliver feedback in real time without disrupting the wearer or the conversation partner. Additionally, we provide suggestions for wearable assistive technologies for social support.
Effect of Preoperative Mastoid Ventilation on Tympanoplasty Success

Purpose. This study was conducted with the aim of investigating the relationship between mastoid air cell volumes and graft success after tympanoplasty. Material and Methods. This study was performed retrospectively with patients undergoing type I tympanoplasty and antrostomy. A total of 57 patients (20–35.09% female and 37–64.91% male) with a mean age of 29.69 ± SD (range 12–56 years) were included in the study. The patients were invited for a control at the 1st, 3rd, and 12th months, and otoscopic examinations and audiometric tests were performed. The temporal bone computed tomography images were screened with the 4800 Dpi optic resolution scanner and transferred to the computer environment in JPG format in order to calculate the mastoid air cell volume, and the volumes were calculated using the Autocad 2007 program. Results. Although, the graft success was determined to be better in the well-ventilated group, no significant difference could be found between the groups in terms of graft success at the 1st, 3rd, and 12th months (P > 0.05). No statistically significant difference could be found between the three groups in terms of the preoperative and postoperative hearing gains (P > 0.05).
Cholinergic Modulation of GABAergic Inhibition Dynamics In The Striatum

The striatum contains medium spiny neurons (MSNs) classified by their axonal projection and expression of dopamine receptors into D1+ and D2+ MSNs; and interneurons including choline acetyltransferase expressing interneurons (ChAT+) that influence MSN activity by triggering GABA release. Here, I identify the potential source of this GABA. In addition, I characterize GABAA receptors that mediate the GABA response produced by distinct classes of neurons. By studying nAChR mediated response in MSNs and in GABAergic interneurons classified as neuropeptide Y (NPY+), parvalbumin (PV+) and tyrosine hydroxylase (TH+), I show direct nAChR mediated response in interneurons but not MSNs, where the response is indirect and mediated through GABAA receptors. To identify the neurons that mediate this GABA response, I performed dual recordings from GABAergic interneurons and MSNs. TH+, PV+, and NPY+ NGF interneurons all form synapses on MSNs, but only TH+ and NPY+ NGF interneurons contribute to nAChR mediated GABAergic responses in MSNs. Through different firing patterns that produce transient and sustained GABA conductance in MSNs, GABAergic interneurons adapt distinct physiological roles. By performing single and dual recordings, I report distinct GABA responses produced by PV+ and NPY+ NGF interneurons. In MSNs, phasic current is mediated by synaptic GABAA receptors containing α2, γ2 and a β subunit; whereas tonic GABA current is mediated by extrasynaptic receptors containing α4, δ (adult mice), and α5 (young mice) subunit. Using β3 and δ subunit selective drugs in mice that lack either subunit, I found that the
Membrane fusion mediated by the influenza virus hemagglutinin requires the concerted action of at least three hemagglutinin trimers

In this study we tested the hypothesis that fusion mediated by the influenza virus hemagglutinin (HA) is a cooperative event. To so this we characterized 3T3 cell lines that express HA at nine different defined surface densities. HA densities ranged from 1.0 to 12.6 x 10(3) HA trimers/microns2 as determined by quantitative fluorescent antibody binding. The lateral mobility and percent mobile fraction of HA did not vary significantly among these cells, nor did the contact area between HA-expressing cells and target RBCs. The fusion reaction of each HA- expressing cell line was analyzed using a fluorescence dequenching assay that uses octadecylrhodamine (R18)-labeled RBCs. For each cell line we measured the lag time preceding the onset of fusion, the initial rate of fusion, and final extent of fusion. The final extent of fusion was similar for all cell lines, and the initial rate of fusion as a function of HA surface density displayed a Michaelis-Menten-type dependence. However, the dependence of the lag time preceding the onset of fusion on HA surface density was clearly sigmoidal. Kinetic analysis of the data for the reciprocal lag time vs HA surface density, by both a log/log plot and a Hill plot, suggested that the observed sigmoidicity does not reflect cooperativity at the level of formation of HA aggregates as a prerequisite to fusion. Rather, the cooperativity of the process(es) that occur(s) during the lag time arises at a later step and involves a minimum of three, and most likely four, HA trimers. A model is proposed to explain HA cooperativity during fusion.

Abstract / Résumé Using data from the National Longitudinal Survey of Youth (NLSY) for the period spanning the years 1979-1991, this essay examines the impact of employer-provided formal training on the wage profile and on the mobility of young Americans making their transition to the labor market. By exploiting the longitudinal aspect of the data set, we are able to provide some control for unobserved individual and job-match heterogeneity by making use of the methodology proposed by Altonji and Shakotko (ReStud 87). The results show that (i) training with the current employer has a statistically and economically significant positive effect on the wage; (ii) employers seem to reward skills acquired through training with previous employers as much as skills they provide themselves; (iii) workers undergoing training have 18 percent lower starting salaries than other workers; this result is obtained by setting up a starting wage equation and by making use of a variable called "on-the-job training still in progress at the time of the interview" ; (iv) with a hazard model which makes use of multiple employment spells by the same worker (thereby allowing the implementation of fixed-effects methods akin to the conditional logit method), skills acquired …
Hidden Expectations Behind the Promise of the Flipped Classroom

ABSTRACT The purpose of this study was to evaluate the student experience of pre-service teachers in a compulsory primary science education course that adopted a flipped classroom approach. Participants (n = 79) were surveyed at the conclusion of the course exploring their perceptions of engagement, enjoyment, and degree of learning as a result of participating in this course. At the end of this course, the majority of participants indicated they were happy with learning outcomes and enjoyed some aspect of the online videos; however, they also indicated they did not watch all of the eight mandatory weekly videos. In fact, the majority only watched about four out of the eight videos. This paper explores why students were reluctant to engage with the online videos and asks if there is an underlying aspect to flipped classrooms that disengages students.
An Empirical Comparison of Direct Product Profit and Existing Measures of SKU Productivity

DPP (direct product profitability) has been heralded as one of the more important advances in supermarket shelf management, yet its accep­ tance by managers in the industry has been slow. Not only is DPP complex and expensive to calculate, but some question exists about whether decisions based on DPP are different from those based on traditional criteria such as gross margin and movement. A data base of nine dry-grocery categories is used here to compare DPP with other SKU indices. DPP is shown to lead to significantly different rankings in some categories, but not all. A Merchandising Attractiveness Index (MAl) is devised, based on a linear regression of gross margin, dollar sales, unit sales, and shelf area occupied, which yields predicted values ofDPP that are virtually identical to DPP in the nine categories studied. This MAl may be a far less expensive way to implement the basic concept ofDPP. It may also be more transparent to managers for basic merchandising decisions (price, space allocation, promotions).
Diagnostic points and possible origin of osteomyelitis in synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome: a radiographic study of 77 mandibular osteomyelitis cases.

OBJECTIVES To find diagnostic points and to identify the origin of osteomyelitis in synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. METHODS Fifty-two patients with mandibular suppurative osteomyelitis and 25 patients with mandibular osteomyelitis in SAPHO syndrome were included in the study. Radiographic patterns of the lesion, types of periosteal reaction and the presence of external bone resorption and bone enlargement were investigated in each case and compared between the two entities. RESULTS Suppurative osteomyelitis demonstrated an osteolytic pattern and a lamellated type of periosteal reaction, whereas SAPHO syndrome revealed a mixed-pattern, solid-type periosteal reaction, external bone resorption and bone enlargement. CONCLUSIONS Radiographic examination is suggested to be convenient and a useful diagnostic method of differentiating osteomyelitis in SAPHO syndrome from suppurative osteomyelitis. The periosteum is suspected to be the original site of osteomyelitic lesions in SAPHO syndrome.
