Crazy Women and Crazier Men: Mental Illness and Gender in Television Shows and Fan Conversations

This study explores the gendering of depictions of mental illness in television shows and how their viewers discuss these depictions. I paid special attention to elements of stigma in the television shows, and analyzed how stigma differed based on gender. I qualitatively analyzed three episodes from ten different shows each, with an even split in the genders of the characters with mental illness on which the analysis centered. In addition, I also qualitatively analyzed ten Reddit conversations, one about each show, to explore what the viewers took away from these depictions of mental illness and how they discussed them with others. The results revealed that depictions of mental illness are indeed gendered, as depictions of men with mental illness reinforced the dangerousness of masculinity, and depictions of women with mental illness reinforced the passivity of femininity. I also found that there were some elements that contradicted these traditional gender roles, depicting men as submissive and emotional and women as active. The Reddit threads showed that viewers of these shows were noticing similar aspects of these depictions, though these results emphasized the female characters’ reckless behavior to a greater extent than was shown in the actual television shows. In exploring how mental illness and gender are socially constructed both independently and in relation to each other, this study reveals a complicated navigation of different sets of social expectations and potentials for stigmatization that accompany mental illness and the successful performance of gender

The influence of parents’ activities in the school and parents’ communication through social media on educational management in Israeli schools

Greater involvement of parents and the school community in educational management decisions has brought about changes in the management of the schools. Over the past few decades, reforms to the education system in Israel have allowed for greater involvement of parents and the school community in the activities at schools. Concurrently, the growing popularity of social media has created an ease of communication between parents and their children’s educational management teams that has necessitated changes in the educational management of the school community. The purpose of this paper is to provide an overview of studies that examine the changing influence that parents’ involvement in the school through school activities and their communication on social media has on the role of educational management in Israeli schools. A comprehensive review of key publications was conducted to synthesize research findings about changes occurring in educational management of schools in Israel. In the educational management of a school, which enables parental involvement and accommodates parental communications on social media, cooperation and coordination between parents, educational management and the school community, is likely to contribute to maintaining the required balance between positive involvement and overzealous interference.Rosnąca popularność nowych technologii komunikacyjnych zmieniła równowagę sił między rodzicami a zespołami zarządzającymi szkołą ich dzieci. Większa łatwość komunikacji spowodowała wzrost zaangażowania rodziców w szkole, a tym samym zmianę roli dyrektorów szkół w zarządzaniu interesariuszami szkoły. Działania rodziców w szkołach i ich komunikacja za pośrednictwem mediów społecznościowych spowodowały zmniejszenie uzależnienia rodziców od kierownictwa szkoły oraz jej kadry dydaktycznej. Celem artykułu jest zidentyfikowanie i wyjaśnienie ewolucji zaangażowania rodziców w zarządzanie szkołą. Kompleksowy przegląd literatury został wykorzystany do oceny zmieniającego się wpływu zaangażowania rodziców w szkole poprzez działania szkolne i media społecznościowe oraz wpływ, jaki wywarł na zarządzanie szkołą. Wzrost wpływu rodziców na zarządzanie szkołą spowodował wiele pozytywnych zmian, jednakże negatywne reakcje w mediach społecznościowych okazały się szkodliwe dla zarządzania szkołą i środowiska szkolnego. Stwierdzono konieczność nasilenia współpracy i wzajemnej koordynacji działań rodziców, kierownictwa szkoły oraz innych interesariuszy, aby osiągnąć wymaganą równowagę między pozytywnym zaangażowaniem a nadgorliwą ingerencją rodzicó

Efficient Parallel Carrier Recovery for Ultrahigh Speed Coherent QAM Receivers with Application to Optical Channels

This work presents a new efficient parallel carrier recovery architecture suitable for ultrahigh speed intradyne coherent optical receivers (e.g., ≥100 Gb/s) with quadrature amplitude modulation (QAM). The proposed scheme combines a novel low-latency parallel digital phase locked loop (DPLL) with a feedforward carrier phase recovery (CPR) algorithm. The new low-latency parallel DPLL is designed to compensate not only carrier frequency offset but also frequency fluctuations such as those induced by mechanical vibrations or power supply noise. Such carrier frequency fluctuations must be compensated since they lead to higher phase error variance in traditional feedforward CPR techniques, significantly degrading the receiver performance. In order to enable a parallel-processing implementation in multigigabit per second receivers, a new approximation to the DPLL computation is introduced. The proposed technique reduces the latency within the feedback loop of the DPLL introduced by parallel processing, while at the same time it provides a bandwidth and capture range close to those achieved by a serial DPLL. Simulation results demonstrate that the effects caused by frequency deviations can be eliminated with the proposed low latency parallel carrier recovery architecture.Fil: Gianni, Pablo.

MapScholar: A Web Tool for Publishing Interactive Cartographic Collections

MapScholar is an interactive visualization tool for historic map collections. It offers an open-source portal that gives individual scholars the independent means of gathering high-resolution images, analyzing them in rich geospatial contexts, and using them to illustrate new interpretations in the history of cartography and related humanities fields. It joins together data in industry-standard file formats with free and effective data-serving sites such as Flickr and Google Docs to display its on-the-fly visualizations. MapScholar enhances traditional books and articles by making it possible -- at no cost to publishers -- to mount stunning web displays of map collections assembled from libraries around the world. MapScholar’s key innovation is how it brings maps together -- regardless of the archive in which they sit -- for the purpose of generating new knowledge about human perceptions of geographic space

The Role of the Southern Ocean on Global Ocean Circulation and Climate

The Southern Ocean (SO) is a unique and highly dynamic region with strong temperature and salinity gradients. A comparison between satellite-derived salinity and observations indicates strong differences along coastal boundaries, areas of low temperature, and regions of strong currents. Although differences throughout much of the SO are shown to be negligible, resolution and smoothing in the products create large biases in horizontal gradients and errors in estimating the water cycle. The three-dimensional movement of water within the SO plays an important role in the global Meridional Overturning Circulation (MOC), where the Southern Hemisphere westerlies drive both zonal and meridional transports and strong vertical movements of local water masses. Using the Estimating the Circulation and Climate of the Ocean (ECCO) estimates of ocean circulation, recent trends in the lower cell of the MOC (1992-2015) show increased overturning within the South Atlantic and decreased overturning within the Indian and Pacific basins, increasing the net SO heat transports and storage. The path of the Antarctic Circumpolar Current (ACC) is mainly dictated by bathymetry, but recent variability indicates a northward shift in the central South Pacific ACC fronts. The movement and location of the ACC is highly correlated to salinity and temperature shifts up to 100 m depth and moderately correlated to depths of 1000 m. The location of the ACC is weakly-to-moderately correlated with the Antarctic and Southern Oscillations. These large-scale teleconnections are further driving surface cooling in the central South Pacific and warming in the subtropics and mid-latitudes of the Southern Hemisphere. Satellite-derived sea surface temperatures (SSTs) are highly correlated with both the Antarctic and Southern Oscillations during 1982-2016, particularly during the austral summer months when the oscillations tend to be the strongest. Changes in the westerlies are correlated with sea level and heat content anomalies and anti-correlated to SST in the high latitudes. The magnitude of the westerlies has recently increased throughout the ACC region, driving the increase in mid-latitude and decrease in the central South Pacific SST, heat content, and sea level anomalies. These analyses conclude that atmospheric variability is significantly contributing to recent changes in circulation and surface properties
