A Multi-Game Framework for Harmonized LTE-U and WiFi Coexistence over Unlicensed Bands

The introduction of LTE over unlicensed bands (LTE-U) will enable LTE base stations to boost their capacity and offload their traffic by exploiting the underused unlicensed bands. However, to reap the benefits of LTE-U, it is necessary to address various new challenges associated with LTE-U and WiFi coexistence. In particular, new resource management techniques must be developed to optimize the usage of the network resources while handling the interdependence between WiFi and LTE users and ensuring that WiFi users are not jeopardized. To this end, in this article, a new game theoretic tool, dubbed the multi-game framework, is proposed as a promising approach for modeling resource allocation problems in LTE-U. In such a framework, multiple coexisting and coupled games across heterogeneous channels can be formulated to capture the specific characteristics of LTE-U. Such games can be of different properties and types, but their outcomes are largely interdependent. After introducing the basics of the multi-game framework, two classes of algorithms are outlined to achieve the new solution concepts of multi-games. Simulation results are then conducted to show how such a multi-game can effectively capture the specific properties of LTE-U and make of it a “friendly” neighbor to WiFi.
Collaborative crafting in call centre teams

Job crafting research has typically examined the antecedents and outcomes of individual-level crafting. In this study, we test a model of team-level or collaborative job crafting using data collected from 242 call centre teams and supervisors' ratings of team performance. The focus on teams with narrowly defined tasks and limited decision-making responsibility are unique features of this study. As predicted, collaborative crafting was found to relate positively to team efficacy, team control, and team interdependence, which in turn were found to relate positively to work engagement and team performance. The implications for theory development, future research, and practice are discussed. Practitioner points Even in a work environment characterized by low control, there remain opportunities for collaborative job crafting. Collaborative crafting is associated with higher employee engagement and team performance. Call centre supervisors and managers need to be aware of the potential benefits of collaborative crafting to ensure it is not inhibited by their behaviours (such as enhanced monitoring). As positive consequences are associated with collaborative crafting, organizations should consider team training to enhance the collaborative crafting capability of teams.
Oral Health-related Quality of Life in Children and Preadolescents with Caries, Malocclusions or Temporomandibular Disorders.

PURPOSE To compare the oral health-related quality of life (OHRQoL) of children (8- to 10-year-olds) and preadolescents (11- to 14-year-olds) with different oral conditions and to identify concepts associated with their perceptions of oral health (OH) and overall well being (OWB). MATERIALS AND METHODS A cross-sectional study was conducted with 264 students who were distributed into four groups: caries, with the sum of the decayed, missing and filled teeth in the primary (dmft) and permanent dentitions (DMFT) ≥ 1 (n = 72); malocclusion, with the Dental Aesthetic Index (DAI) ≥ 26 (n = 40); temporomandibular disorders (TMD) with at least one sign and one symptom of TMD (n = 89); control, with dmft/DMFT = 0, DAI < 26 and without signs and symptoms of TMD (n = 63). OHRQoL was measured using Portuguese versions of Child Perceptions Questionnaires (CPQ) for children (CPQ8-10) and preadolescents (CPQ11-14). Differences in CPQ scores and in the frequency of responses to global ratings were assessed using Kruskal-Wallis and chi-square/Fisher's exact tests. Multiple linear regression analyses were used to identify items associated with CPQ and global scores. RESULTS The OHRQoL of the TMD group was statistically different from controls. The malocclusion group reported more oral symptoms and social impacts compared to controls. The variables associated with CPQ scores varied according to clinical condition. CONCLUSIONS OHRQoL was significantly different between clinical groups and controls for both age groups. However, when comparing clinical groups, TMD and caries differed only for preadolescents. The items associated with higher OHRQoL scores were mainly psychosocial for caries and TMD groups, and physical/functional and psychosocial for children and preadolescents with malocclusions, respectively.
From long-term savings to instant mortgages: financial demonstration and the role of interaction in markets

Accounts of the crisis have privileged ‘high finance’ innovations whereas retail banks constantly experimented with how they sell (new) products to consumers. I examine the case of product innovation at a home savings bank in Hungary during the pre-crisis credit boom. Turned from offering state-subsidized long-term savings-and-loans to promoting instant mortgages. Based on ethnographic observations of the bank’s Direct Selling Organization, I trace the bank’s shift from state-subsidized long-term savings-and-loans to instant mortgages, to problems with demonstrating the qualities of financial products, even ostensibly prudent ones. Drawing on concepts of scientific demonstration and proof, I compare how financial advisors explained the plan to consumers before and after it was combined with mortgages: first they drew the funds by hand, later they adopted software-generated scenarios. I suggest that as sellers perform products interactively with clients, consumers’ needs appear. Thus, when organized differently, financial demonstrations yield different consumers-with-preferences. Based on this interactional perspective, I find that consumer finance is an ‘economy of qualities’ where preferences and product properties stabilize through consultation, and where “social” embedding can enable “economic” calculations. Based on this interactional perspective, I examine US and UK proposals for consumer financial protection.
c-di-GMP (3′-5′-Cyclic Diguanylic Acid) Inhibits Staphylococcus aureus Cell-Cell Interactions and Biofilm Formation

ABSTRACT Staphylococcus aureus is an important pathogen of humans and animals, and antibiotic resistance is a public health concern. Biofilm formation is essential in virulence and pathogenesis, and the ability to resist antibiotic treatment results in difficult-to-treat and persistent infections. As such, novel antimicrobial approaches are of great interest to the scientific, medical, and agriculture communities. We recently proposed that modulating levels of the cyclic dinucleotide signaling molecule, c-di-GMP (cyclic diguanylate [3′,5′-cyclic diguanylic acid], cGpGp), has utility in regulating phenotypes of prokaryotes. We report that extracellular c-di-GMP shows activity against human clinical and bovine intramammary mastitis isolates of S. aureus, including methicillin-resistant S. aureus (MRSA) isolates. We show that chemically synthesized c-di-GMP is soluble and stable in water and physiological saline and stable following boiling and exposure to acid and alkali. Treatment of S. aureus with extracellular c-di-GMP inhibited cell-to-cell (intercellular) adhesive interactions in liquid medium and reduced (>50%) biofilm formation in human and bovine isolates compared to untreated controls. c-di-GMP inhibited the adherence of S. aureus to human epithelial HeLa cells. The cyclic nucleotide analogs cyclic GMP and cyclic AMP had a lesser inhibitory effect on biofilms, while 5′-GMP had no major effect. We propose that cyclic dinucleotides such as c-di-GMP, used either alone or in combination with other antimicrobial agents, represent a novel and attractive approach in the development of intervention strategies for the prevention of biofilms and the control and treatment of infection.
The Effects of Psychologically Based Intervention Programs on Worker Productivity: A Meta-Analysis.

A meta-analysis of the effects on worker productivity of 11 types of psychologically based organizational interventions showed that such programs, on average, raised worker productivity by nearly one-half standard deviation. The strength of effects was found to vary by type of intervention, criterion of productivity, contextual factors in organizations, and features of research design. Also discussed in the paper are comparisons of conclusions reached through meta-analysis versus traditional methods of literature review.
PERIOD PREVALENCE OF PSYCHIATRIC DISORDERS IN EDMONTON

3,258 randomly selected adult household residents of Edmonton were interviewed by trained lay interviewers using the Diagnostic Interview Schedule (DIS). Six‐month prevalence figures for DIS/DSM III diagnoses are given, and selected figures for the one‐month and one‐year prevalence, and the one‐year symptom‐free rates. The six‐month prevalence for any diagnosis is 17.1%, comparable to findings from other population studies using DSM III derived diagnoses, but lower than studies using the PSE. The prevalence rates for most disorders tended to be lowest in the elderly, but this was not as marked as the drop in lifetime prevalence. Men had higher prevalence for substance use disorders than women, but women had higher rates for affective disorders and anxiety/somatoform disorders. Prevalences for all disorders were either similar or lower in those who were married or living as though married, than in those who were not cohabiting. One‐year symptom‐free rates were highest for those with substance use disorders and lowest for those with anxiety/somatoform disorders ‐ largely due to the persistence of phobias.
Eliminating Arterial Injury During Central Venous Catheterization Using Manometry

BACKGROUND: Unintended arterial puncture occurs in 2%-4.5% of central venous catheterizations, resulting in arterial injury in 0.1%-0.5% of patients. Routine performance of manometry during catheterization may successfully identify unintended arterial puncture and avoid arterial cannulation and injury. METHODS: We conducted a retrospective review of all cases of central venous catheter placement during a 15-yr period after implementation of a safety program requiring mandatory use of manometry to verify venous access. Arterial injuries were defined as unintended arterial cannulations with a 7-French or larger catheter or dilator. Arterial punctures were defined as the unintended placement of an 18-gauge catheter or needle into the artery. Data were reviewed for all arterial injuries during the entire 15-yr period. In addition, data on both arterial puncture and subsequent arterial injury were evaluated during the final year of analysis. RESULTS: A total of 9348 central venous catheters were placed during the observation period. During the full 15 yr of observation, there were no cases of arterial injury. During the final year of assessment, 511 central venous catheters were placed, with arterial punctures in 28 patients (5%). Arterial puncture was recognized without manometry in 24 cases. Arterial puncture was identified only with manometry in 4 cases, with no incidents of arterial injury. CONCLUSIONS: Consistent use of manometry, to verify venous placement, during central venous catheterization effectively eliminated arterial injury from unintended arterial cannulation during the 15-yr assessment.
‘There Are Some Daft People Out There!’: exploring female sport and media fandoms

Female sports fans have been largely marginalized in academic research, but this article makes one contribution towards changing this relative invisibility. Drawing on a ‘grounded theory’ approach, 85 semi-structured interviews were conducted with female football (soccer) and rugby union fans in the English city of Leicester. This article explores how these women position themselves in relation to stereotypes about female media/soap opera fans. Whilst some sports fans were keen to reaffirm hierarchies between sports and media fandoms, others emphasized the extant similarities between these different types of fandom, illustrating the heterogeneity of women's sporting experiences and the range of their interpretations of fandom. My findings concur with Schimmel et al.'s assertion (Schimmel et al. ‘Keep Your Fans to Yourself’, 593) that there is a need for greater ‘cross-fertilization’ between sports and media fandoms. This could help to prompt a move away from gendered hierarchies in research and move towards putting women's experiences as sports fans on the research agenda.
Review of Singapore's air quality and greenhouse gas emissions: Current situation and opportunities

Singapore has many environmental accomplishments to its credit. Accessible data on air quality indicates that all criteria pollutants satisfy both U.S. Environmental Protection Agency (EPA) and World Health Organization (WHO) air quality standards and guidelines, respectively. The exception is PM2.5 (particles with an aerodynamic diameter ≤2.5 μm), which is not currently considered a criteria pollutant in Singapore but may potentially be the major local air pollution problem and cause for health concern. Levels of other airborne pollutants as well as their physical and chemical processes associated with local formation, transformation, dispersion, and deposition are not known. According to available emission inventories, Singapore's contribution to the total atmospheric pollution and carbon budget at the regional and global scales is small. Emissions per unit gross domestic product (GDP) are low compared with other countries, although Singapore's per-capita GDP and per-capita emissions are among the highest in the world. Some information is available on health effects, but the impacts on the ecosystem and the complex interactions of air pollution and climate change at a regional level are also unknown. This article reviews existing available information on atmospheric pollution and greenhouse gas emissions and proposes a multipollutant approach to greenhouse gas mitigation and local air quality. Singapore, by reducing its per-capita emissions, increasing the availability of information (e.g., through regularly publishing hourly and/or daily PM2.5 concentrations) and developing a research agenda in this area, would likely be seen to be a model of a high-density, livable, and sustainable city in Southeast Asia and other tropical regions worldwide. Implications Singapore is widely recognized for its environmental achievements and often cited as a model of a high-density, livable, and sustainable city. This article reviews available information with the aim to provide a reference for future scientific research of strategic relevance for Singapore's air quality and greenhouse gas mitigation management under a multipollutant framework. However, the limited publicly accessible data and little scientific information prevent a comprehensive assessment of the local air quality and greenhouse gas emissions. Singapore's dynamic economy and strong profile in advanced science and technological innovation have the potential to enhance the research agenda in this area, which is not yet well developed in tropical cities.
Transient Partial hGH Deficiency in Prepubertal Children with Delay of Growth

Summary: The hGH response to an ornithin or an insulin test was measured in 105 children from 11–18 yr old with delay of growth more than 2 SD. Besides 74 subjects with normal values and 7 with complete lack of response, 24 subjects exhibited a partial rise of GH. Most of the latter had decreasing growth rate and no sign of puberty. Out of 15 assessed for GH function after onset of puberty, 14 showed a normal response accompanying a markedly increased growth velocity. Four other subjects with partial response who were receiving sexual hormones for 48 hr before the second test showed a normal response also. An exogenous hGH treatment administered in two of these patients resulted in a marked and sustained growth increase far before entering puberty.Speculation: The findings that plasma GH responses to stimulation tests is reduced in some children with decreasing growth rate before puberty and return to normal after onset of sexual development, would suggest a transient and functional defect in growth hormone secretion and the physiologic role of sexual hormones on GH release mechanism at that period of life.
Parental reflective functioning and executive functioning in mothers with substance use disorder

ABSTRACT Having a substance use disorder (SUD) may adversely affect caregiving capacities. Reflective functioning (RF) and executive functioning (EF) are both important capacities for sensitive parenting, and are often impaired in a SUD. Only a few studies have explored the possible association between the two phenomena. In this study, we used a neuropsychological test battery to assess EF, and the Parent Development Interview to assess RF in a sample of mothers with a SUD (N = 43). Although parental RF (PRF) was associated with EF, when controlled for intelligence (IQ) and mental health, there was no significant association between EF and PRF. Mental health, however, showed a significant negative association with PRF. Splitting the group in two based on PRF level, mothers with a negative to low PRF exhibited more severe difficulties in SUD-related aspects, as well as in several EF components, compared to mothers with an adequate to high PRF, highlighting the association between EF and PRF. The results from this study contribute to enhance our understanding of the dynamics underlying vulnerability in PRF that mothers with small children may experience. We suggest EF to be a prerequisite for adequate PRF, and for interventions to be customized accordingly regarding parents with a SUD.
Biased evaluation of incriminating and exonerating (non)evidence

Abstract Recent evidence suggests that convictions in criminal procedures are susceptible to biased decision making. In this study, the potential detrimental effects of confirmation bias and the feature positive effect (FPE) were explored. The former states that decision-makers will be more impressed by incriminating than by exonerating evidence. The latter states that they assign more weight to finding evidence than to the failure to secure it, even though the absence of evidence can be as diagnostic as its presence. Law students read a case file about a fistfight. The evidence was manipulated such that the effect of confirmation bias and FPE on guilt estimation and conviction rate could be assessed. Findings partly confirmed the presence of both a confirmation bias and an FPE.
Combining scaffolds and osteogenic cells in regenerative bone surgery: a preliminary histological report in human maxillary sinus augmentation.

PURPOSE The following case series evaluated the maxillary sinus augmentation responses to tissue-engineered bone graft obtained by a culture of autogenous osteoblasts seeded on polyglycolic-polylactic scaffolds and calcium phosphate. MATERIALS AND METHODS Sinus floor augmentation was performed bilaterally in five patients (mean age 58.4 years) with tissue-engineered bone (test site - Oral Bone, BioTissue, Freiburg, Germany) or calcium phosphate (control site - Biocoral, Novaxa Spa, Milan, Italy). Biopsies were harvested 6 months after sinus augmentation for histometric evaluation. Volumetric measurements were taken at baseline and 6 months after the surgical procedure. RESULTS The mean of vertical bone gain was 6.47 +/- 1.39 mm and 9.14 +/- 1.19 mm to test and control sites, respectively. The histological sections depicted mature bone with compact and cancellous areas. All biopsies contained varying percentages of newly formed bone and marrow spaces. The mean of bone tissue in the grafted area was 37.32 +/- 19.59% and 54.65 +/- 21.17% for tissue-engineered bone and calcium phosphate, respectively. CONCLUSION Within the limits of the present report, the histological data in humans confirmed that tissue-engineered bone and calcium phosphate allowed newly formed bone after maxillary sinus augmentation.
Motivation and Leisure Satisfaction of Mass Media Use among Hong Kong Adolescents

Abstract This paper examines the role of mass media use as leisure activity among Hong Kong adolescents. It specifically investigates the reasons for using different mass media and the leisure satisfaction derived from this use. Data collected through a questionnaire administered to students (n=7570) were subjected to descriptive and structural equation modeling analysis. Results indicate that adolescents use mass media for expressive, social, relaxation and intellectual reasons and different mass media serve different functions. Age and gender differences are found in relation to the reasons for using mass media and the leisure satisfaction derived from that use. The older the adolescents, the more they tend to use the various types of mass media for expressive, social and intellectual reasons. Females are found to derive more leisure satisfaction from participation in mass media activities than from other leisure activities. Females also derive mostly the educational type of leisure satisfaction and especially from engaging in reading. Overall, the study sheds light on the positive aspects of mass media use among adolescents and thus balances the recent trend of focusing on their adverse effects. It further calls attention to the roles of a wide range of mass media, and to age and gender differences in mass media use which deserve further examination.
Race, Culture, and Autism Spectrum Disorder: Understanding the Role of Diversity in Successful Educational Interventions

The reported prevalence of autism spectrum disorder (ASD) has increased dramatically since the 1980s. In response, researchers, educators, and policy makers have sought to develop effective technologies for assessment and intervention. A focus on evidenced-based practices is logical, given significant deficits in language, social interaction, cognition, and adaptive behavior that comprise these conditions. Although critical, a technology of best practices is insufficient without understanding the important role that diversity plays in helping persons with ASD, particularly those with the most severe impairments, to lead fulfilling lives. The aim of the current article is threefold. First, we explore the concept of diversity with particular attention to neurodiversity among persons with ASD. We describe how cultural and linguistic diversity influence identification of students with ASD in special education, with data to suggest that racially diverse students are underrepresented in the autism category. We then examine the educational process with particular focus on the impact of parent and family culture on perception of disability, the influence of diverse family systems on interventions, and the successful interventions for diverse contexts. We conclude with recommendations for culturally competent practice and research.
The Effect of Liming and Fertilization on Yields of Maize and Winter Wheat

SUMMARY Effect of different rates of hydrated lime and zeolite tuffs, as lime materials, mineral and organic fertilizers upon the yield of maize and winter wheat grain was studied in an exact field trial set up on Eutric Gleysol, near Karlovac, Central Croatia. The following crops were cultivated during the study period: 1999 and 2001 – maize, 1999/00 and 2001/02 – winter wheat. In the first investigation year, the highest yield of maize grain of 9.78 t ha -1 was achieved with the combination of the higher mineral fertilizer rate and the higher rate of farmyard manure. In the following year, the highest yield of winter wheat grain of 5.85 t ha -1 was achieved with the combination of the higher mineral fertilizer rate and the higher rate of hydrated lime. In the third and fourth investigation years, the highest yields of maize grain (10.05 t ha -1 ) and wheat (5.48 t ha -1 ) were recorded for the combination of the higher rates of mineral fertilizers and hydrated lime. The foregoing allows the conclusion that mineral and organic fertilization combined with hydrated lime is the optimal solution for increasing the yields of test crops.
