The Gender of TV Expertise: A Combined Quantitative/Qualitative Analysis of Israeli TV Talk Shows

This combined quantitative/qualitative study is based on a content analysis of 238 hours of Israeli talk shows from 2012 and semiotic analysis of selected programs to map the gender distribution of TV experts and explore potential differences in the way men and women are treated in the programs.. All in all, 495 experts were coded. Men experts outnumbered women experts in a 1.7 to 1 ratio. These men were signifi cantly older than the women and tended to have a higher academic rank, but they were not treated more favorably during the program. In fact, experts of both genders were criticized or disagreed with in just less than 4% of the cases. The topics on which the experts commentated refl ect familiar gender stereotypes with men more likely to talk about security, politics and economy and women more often talk about body grooming and child care. The results, which partly accord with feminist criticisms of the popular media, are analyzed in relation to the theoretical concepts of symbolic annihilation and “fast thinking” and the fi ndings of studies that looked at the gender of scientists and scholars in other TV genres

Some Basic Properties of Low Quality Two-Phase Turbulent Flow

This Is an exploratory study dealing with the effect of gas bubbles on the turbulence Intensity of the liquid in a two-phase flow. Distributions of time-mean and fluctuating velocities were measured in a two - dimensional channel. These were measured for single-phase flow and on the two sides of a bubble layer, which simulated the two-phase flow. In single-phase flow the distribution of the time-mean velocities agrees well with other data, while the distribution of the Intensity of turbulence Is lower than expected. The measurements of the time-mean velocity and turbulence Intensity across the bubble layer revealed that they are discontinuous at that point. This supports the hypothesis that the presence of bubbles in liquid flows tends to lower the intensity of turbulence

STATIC AND DYNAMIC ANALYSIS OF THE FOOT IN SOCCER PLAYERS SUSTAINING PROXIMAL 5TH METATARSAL STRESS FRACTURE

Stress fracture of the proximal 5th metatarsal (MT) is a well recognized entity among athletes. Identification of specific risk factors for this injury may play an important role injury prevention. Lateral oveloading in rigid cavus foot have been suggested as contributing factors (Williams, 2001). The purpose of our study was to characterize static variables of foot structure and dynamic variables of foot function in soccer players which sustained 5th MT stress fracture

Arthroscopic Treatment of Acetabular Retroversion With Acetabuloplasty and Subspine Decompression: A Matched Comparison With Patients Undergoing Arthroscopic Treatment for Focal Pincer-Type Femoroacetabular Impingement.

BackgroundGlobal acetabular retroversion is classically treated with open reverse periacetabular osteotomy. Given the low morbidity and recent success associated with the arthroscopic treatment of femoroacetabular impingement (FAI), there may also be a role for arthroscopic treatment of acetabular retroversion. However, the safety and outcomes after hip arthroscopic surgery for retroversion need further study, and the effect of impingement from the anterior inferior iliac spine (subspine) in patients with retroversion is currently unknown.HypothesisArthroscopic treatment for global acetabular retroversion will be safe, and patients will have similar outcomes compared with a matched group undergoing arthroscopic treatment for focal pincer-type FAI.Study designCohort study; Level of evidence, 2.MethodsPatients undergoing hip arthroscopic surgery for symptomatic global acetabular retroversion were prospectively enrolled and compared with a matched group of patients undergoing arthroscopic surgery for focal pincer-type FAI. Both groups underwent the same arthroscopic treatment protocol. All patients were administered patient-reported outcome (PRO) measures, including the 12-item Short-Form Health Survey (SF-12) Physical Component Summary (PCS) and a Mental Component Summary (MCS), modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), and visual analog scale (VAS) for pain preoperatively and at 1 year postoperatively.ResultsThere were no differences in age, sex, or body mass index between 39 hips treated for global acetabular retroversion and 39 hips treated for focal pincer-type FAI. There were no major or minor complications in either group. Patients who underwent arthroscopic treatment for global acetabular retroversion demonstrated similar significant improvements in postoperative PRO scores (scores increased by 17 to 43 points) as patients who underwent arthroscopic treatment for focal pincer-type FAI. Patients treated for retroversion who also underwent subspine decompression had greater improvement than patients who did not undergo subspine decompression for the HOOS-Pain (33.7 ± 15.3 vs 22.5 ± 17.6, respectively; P = .046) and HOOS-Quality of Life (49.7 ± 18.8 vs 34.6 ± 22.0, respectively; P = .030) scores.ConclusionArthroscopic treatment for acetabular retroversion is safe and provides significant clinical improvement similar to arthroscopic treatment for pincer-type FAI. Patients with acetabular retroversion who also underwent arthroscopic subspine decompression demonstrated greater improvements in pain and quality of life outcomes than those who underwent arthroscopic treatment without subspine decompression

Experimental investigation of non-uniform heating effect on flow boiling instabilities in a microchannel-based heat sink

Copyright @ 2011 ElsevierTwo-phase flow boiling in microchannels is one of the most promising cooling technologies for coping with high heat fluxes produced by the next generation of central processor units (CPUs). If flow boiling is to be used as a thermal management method for high heat flux electronics it is necessary to understand the behaviour of a non-uniform heat distribution, which is typically the case observed in a real operating CPU. The work presented is an experimental study of two-phase boiling in a multi-channel silicon heat sink with non-uniform heating, using water as the cooling liquid. Thin nickel film sensors, integrated on the back side of the heat sinks were used in order to gain insight related to temperature fluctuations caused by two-phase flow instabilities under non-uniform heating. The effect of various hotspot locations on the temperature profile and pressure drop has been investigated. It was observed that boiling inside microchannels with axially non-uniform heating leads to high temperature non-uniformity in the transverse direction.This research was supported by the UK Engineering and Physical Sciences Research Council through grant EP/D500109/1

Vjerske prakse i razgovori o religiji u elitnim terminima američke i izraelske televizije

This comparative content analysis examines the extent to which religion finds expression in mainstream TV programming. The appearance of religious practices, the level of fulfillment they bring, and the extent to which they accord with religious law along with the tone of conversation about religion were coded in 154 hours of prime-time network programming from the USA and 112 hours of prime-time programming aired by the major TV stations in Israel. The results indicate a very infrequent presence of religion in the programming in the two countries: once in two hours in Israel and once in three hours in the USA, but while in US programming more than three quarters of the religious practices brought fulfillment to their participants and more than 90% of the practices adhered fully or partly to religious rules, in Israeli shows only one quarter of the practices brought fulfillment and just half of them adhered fully or partly to religious rules. Conversation about religion appeared just as infrequently as practices did, but its tone was mainly positive in both countries.Ova usporedna analiza sadržaja istražuje u kojoj je mjeri religija prisutna u matičnom (mainstream) televizijskom programiranju. Pojava vjerskih praksi, razina ispunjenja koju donose i njihova usklađenost s vjerskim zakonima, kao i ton kojim se razgovora o religiji, kodirani su unutar 154 sata elitnih programskih termina u SAD-u, odnosno unutar 112 sati udarnog termina koji emitiraju glavne televizijske kuće u Izraelu. Rezultati pokazuju vrlo malu prisutnost religije u TV-programima dviju zemalja: jednom u dva sata u Izraelu i jednom u tri sata u SAD-u. Ali dok je religijskim programskim sadržajima u SAD-u ispunjenje postiglo više od tri četvrtine sudionika i više od 90 % emisija potpuno je ili djelomično poštovalo religijska pravila, u Izraelu je samo jedna četvrtina sudionika doživjela ispunjenje, a samo polovica emisija potpuno je ili djelomično slijedila vjerska pravila. Razgovor o religiji bio je podjednako malo zastupljen kao i same vjerske prakse, ali je ton razgovora bio uglavnom pozitivan u obje zemlje

FOOT PRONATION AND STRESS FRACTURES OF THE FEMUR AND TIBIA: A PROSPECTIVE BIOMECHANICAL STUDY

The relation between foot pronation and stress fractures has been suggested. However, evidence based literature is lacking and contradictory. The purpose of this study was to examine whether dynamic parameters of foot pronation are related to the development of stress fractures of the femur and tibia. 2 weeks prior to beginning of 14 weeks of basic military training, 473 infantry recruits were inrolled into the study. 2D analysis was performed to measure foot pronation during treadmill walking. The soldiers were examined during the training course at two weeks intervals for stress fractures. The odds ratio was calculated for each dynamic pronation parameter in relation to the stress fractures. 10% of the 405 soldiers who finished the training were diagnosed with stress fractures of the femur and tibia. Longer pronation time was related to risk reduction for the development of stress fractures and may have a protective effect during an extended period of training

Effect of wire diameter on ultrasonic enhancement of subcooled pool boiling

Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.New methods for cooling of microelectronic elements have been recently developed, including application of ultrasonic fields. Ultrasonic fields enhance the heat transfer in two-phase cooling. The present work deals with ultrasonic enhancement of heat transfer from wires in sub-cooled pool boiling. The experiments have been carried out using three wires of different diameters: 0.05, 0.09, 0.2mm, submerged into a bath with water. The applied ultrasonic field was of frequency of 40 kHz and intensity of 0.5 W/cm2. The wire wall temperature was measured as a function of wire surface heat flux. When the ultrasonic field was applied, the wall temperature reduced in the range of measured heat fluxes. The temperature difference increased with the heat flux. It also increased with the wire diameter. At the smallest diameter only a small decrease of the wall temperature, about 10-15 degrees, was observed, while at larger diameters the decrease of the wall temperature was about 30 - 35 degrees.dc201

Pin fin two-phase micro gap coolers for concentrating photovoltaic arrays

Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.Concentrating photovoltaic (CPV) systems are among the most promising renewable power generation options but will require aggressive thermal management to prevent elevated solar cell temperatures and to achieve the conversion efficiency, reliability, and cost needed to compete with alternative techniques. Two-phase, evaporative cooling of CPV modules has been shown to provide significant advantages relative to single-phase cooling but, to date, the available two-phase data has been insufficient for the design and optimization of such CPV systems. This Keynote lecture will begin with a brief review of CPV technology and the solar cell cooling techniques described in the literature. Energy modeling, relating the harvested solar energy to the “parasitic” work expended to provide the requisite cooling, will be used to support the efficacy of twophase cooling for CPV applications. Attention will then turn to the available correlations for pin-finned microgap coolers and the gaps which must be addressed to enable such thermal management for CPV arrays. This will be followed by a detailed description of an experimental study of 3 pin-finned microgap coolers for CPV systems and the derived heat transfer and pressure drop correlations. The data spans a large parametric range, with heat fluxes of 1 - 170 W/cm2, mass fluxes of 10.7 - 1300 kg/m2-s, subcooled (single phase) flow as well as exit qualities up to 90%, and 3 heat transfer fluids (water, HFC-134a, HFE-7200). The lecture will close with a brief case study of two-phase CPV cooling, demonstrating that the application of this thermal management mode can lead to a highly energy efficient CPV system.dc201

Isokinetic moment curve abnormalities are associated with articular knee lesions

The aim of this study was to test whether lesions of the medial meniscus (MM) and of the anterior cruciate ligament (ACL) are associated with specific abnormalities of isokinetic moment curves (IMCs). Fifty-four young adults (20 active healthy people, and 34 patients with unilateral knee injuries) were assessed through knee extensor and flexor isokinetic tests at 60\ub0/s. Qualitative IMC analysis was performed using a novel classification system which identified three distinct abnormal shapes. The chi-squared (\u3c72) test was used to determine the inter-individual and intra-individual differences between the groups. Quantitative IMC inter-group comparisons were performed by a one-way analysis of variance (ANOVA). Knees with MM and ACL lesions were consistently associated with IMC shape irregularities (p<0.001) and with abnormal quantitative scores (p<0.001). More specifically, knees with isolated ACL lesions and knees with combined ACL and MM lesions presented similar distribution of knee extensor and flexor IMC irregularities, which was not present in knees with isolated MM lesions. A possible association between specific knee pathologies and IMC irregularities was identified (all p<0.05). In conclusion, different knee pathologies may be associated with different qualitative IMCs, which could be used as an additional presentation tool in clinical settings
