It\u27s a Very Silent Pain : A Phenomenological Study of Women Who Are in a Relationship with a Sexually Addicted Spouse

Being in a relationship with someone who is sexually addicted has been recognized as disorienting and painful. What is lacking in the literature is inclusion of the voices of those individuals who have been affected by his behaviour. This study attempts to capture the phenomenon experienced by those individuals who are in a relationship with a person who is sexually addicted. Twelve women, who identified being in a current or past relationship with a person who is sexually addicted, participated in qualitative interviews where they were encouraged to share their experiences. The interviews were analyzed within the transcendental phenomenological framework. Three themes were identified: discovery/acknowledgment, living with the knowing, and healing. Within these themes, a number of sub-themes were identified. These findings are discussed and examined, contributing new insight to the current literature regarding individuals who have experienced this phenomenon

Using Long-Term Data From Antarctica to Teach Ocean Acidification

There is a mystery to be solved! This lesson plan asks students to identify the Who, What, When, Where, Why, and How of ocean acidification (OA). Global oceans have absorbed approximately a third of the CO2 produced by human activities, such as burning of fossil fuels, over the past decade (Sabine et al. 2004). This accumulation of CO2 in the ocean has lowered average global ocean pH and decreased the concentration of carbonate ions (CO/ ) (Fabry et al. 2008). As a result of this OA, the carbonate chemistry of the global ocean is rapidly changing and affecting marine organisms (Orr et al. 2005). Pteropods (open-ocean snails) are considered bioindicators of OA due to the vulnerability of their aragonitic shells dissolving under increasingly acidic conditions from a changing climate (Figure 1) (Orr et al. 2005; Bednarsek et al. 2014).

A Millimeter-Wave Achromatic Half Wave Plate

We have constructed an achromatic half wave plate (AHWP) suitable for the millimeter wavelength band. The AHWP was made from a stack of three sapphire a-cut birefringent plates with the optical axes of the middle plate rotated by 50.5 degrees with respect to the aligned axes of the other plates. The measured modulation efficiency of the AHWP at 110 GHz was $96 \pm 1.5$%. In contrast, the modulation efficiency of a single sapphire plate of the same thickness was $43 \pm 4$%. Both results are in close agreement with theoretical predictions. The modulation efficiency of the AHWP was constant as a function of incidence angles between 0 and 15 degrees. We discuss design parameters of an AHWP in the context of astrophysical broad band polarimetry at the millimeter wavelength band.Comment: In print - Applied Optics, 14 pages, 7 figure

Diel Vertical Distribution Patterns of Zooplankton along the Western Antarctic Peninsula

The Western Antarctic Peninsula (WAP) is a region that has undergone significant change over the past several decades due to unprecedented increases sea surface temperature and decreases in sea ice cover. The ongoing Palmer Antarctica Long-Term Ecological Research (PAL LTER) study shows that these environmental changes are significantly affecting the marine pelagic ecosystem along the WAP. The goal of this study was to analyze diel vertical distribution patterns of zooplankton along the WAP

SHARED HISTORY, DIVERGENT PATHS: THE DETERMINANTS OF A SOCIALLY DEMOCRATIC SOCIETY COMPARING THE UNITED KINGDOM TO THE UNITED STATES

This study seeks to demonstrate how the national histories of the United Kingdom and United States shape modern democratic practices in the areas of; 1) minimum income; 2) healthcare; and 3) higher education. Through the use of five testing methodologies, 1) social; 2) geographic; 3) economics; 4) history; and 5) modern day political structure, the following work attempts to more clearly frame questions surrounding democracy in the present perspective and upon a potentially predictive spectrum. Seven distinct findings were brought forward through this study; 1) Federalism is fundamental; 2) Unique geographic variables provide specific direct outcomes to both the United Kingdom and the United States’ sense of self and ensuing approaches to policy making; 3) A historical mentality of self-sufficiency and perceived ruggedness pervades United States political theory and policy making; 4) Cultural mores surrounding the manners and exceptions of citizens to engage with governments directly interplay into the way policy is created, enacted, and regulated in an ongoing manner. Assumed and acted upon relationships matter. The American historical context leads to their citizens having more so; 5) Religiousness and a sense of philanthropic charity does not define nor does it indicate a society will trend towards socialism; 6) From a study of the two most prominent Anglo-Saxon governments. Clearly, inertia is inevitable; 7) The sense of ‘Other’ influences policy in both nations as much as the tangibility of citizen; 8) Parent to child relationship sharing continues but has morphed to alternate over the centuries; as from the start they are more alike than different

A Mollicutes Metagenome-Assembled Genome from the Gut of the Pteropod Limacina rangii

A nearly complete genome of an uncultured Mollicutes sp. was obtained from the metagenome of the gut of Limacina rangii (open-ocean snail), an important grazer and prey for higher trophic animals along the rapidly warming region of the western Antarctic Peninsula

The feeding ecology and microbiome of the pteropod Limacina helicina antarctica

The pteropod (pelagic snail) Limacina helicina antarctica is a dominant grazer alongthe Western Antarctic Peninsula (WAP) and plays an important role in regional food web dynamics and biogeochemical cycling. For the first time, we examined the gut microbiome and feeding ecology of L. h. antarctica based on 16S and 18S rRNA gene sequences of gut contents in the WAP during austral summer. Eukaryotic gut contents of L. h. antarctica indicate that this species predominantly feeds on diatoms and dinoflagellates, supplementing its diet with ciliates and foraminifera. Mollicutes bacteria were a consistent component of the gut microbiome. Determining the gut microbiome and feeding ecology of L. h.antarctica aids in identifying the underlying mechanisms controlling pteropod abundance and distribution in a region of rapid environmental change

Zooplankton diel vertical migration during Antarctic summer

Zooplankton diel vertical migration (DVM) during summer in the polar oceans is presumed to be dampened due to near continuous daylight. We analyzed zooplankton diel vertical distribution patterns in a wide range of taxa along the Western Antarctic Peninsula (WAP) to assess if DVM occurs, and if so, what environmental controls modulate DVM in the austral summer. Zooplankton were collected during January and February in paired day-night, depth-stratified tows through the mesopelagic zone along the WAP from 2009-2017, as well as in day and night epipelagic net tows from 1993-2017. The copepod Metridia gerlachei, salp Salpa thompsoni, pteropod Limacina helicina antarctica, and ostracods consistently conducted DVM between the mesopelagic and epipelagic zones. Migration distance for M. gerlachei and ostracods decreased as photoperiod increased from 17 to 22 h daylight. The copepods Calanoides acutus and Rhincalanus gigas, as well as euphausiids Thysanoessa macrura and Euphausia crystallorophias, conducted shallow (mostly within the epipelagic zone) DVMs into the upper 50 m at night. Rhincalanus gigas, T. macrura, and L. h. antarctica DVM behavior was modulated by chlorophyll a concentration, mixed layer depth, and depth of the subsurface chlorophyll a maximum, respectively. Carnivorous and detritivorous taxa – including the calanoid copepod Paraeuchaeta antarctica, ostracods, chaetognaths, and Tomopteris spp. polychaetes – as well as seasonally migrating copepods, were most abundant in the mesopelagic zone regardless of the diel cycle. Paraeuchaeta antarctica underwent reverse DVM within the top 100 m. The impacts of Antarctic zooplankton summer DVM and the resident mesopelagic assemblage on carbon export should be better quantified

What motivates academic dishonesty in students? A reinforcement sensitivity theory explanation

BACKGROUND: Academic dishonesty (AD) is an increasing challenge for universities worldwide. The rise of the Internet has further increased opportunities for students to cheat. AIMS: In this study, we investigate the role of personality traits defined within Reinforcement Sensitivity Theory (RST) as potential determinants of AD. RST defines behaviour as resulting from approach (Reward Interest/reactivity, goal-drive, and Impulsivity) and avoidance (behavioural inhibition and Fight-Flight-Freeze) motivations. We further consider the role of deep, surface, or achieving study motivations in mediating/moderating the relationship between personality and AD. SAMPLE: A sample of UK undergraduates (N = 240). METHOD: All participants completed the RST Personality Questionnaire, a short-form version of the study process questionnaire and a measure of engagement in AD, its perceived prevalence, and seriousness. RESULTS: Results showed that RST traits account for additional variance in AD. Mediation analysis suggested that GDP predicted dishonesty indirectly via a surface study approach while the indirect effect via deep study processes suggested dishonesty was not likely. Likelihood of engagement in AD was positively associated with personality traits reflecting Impulsivity and Fight-Flight-Freeze behaviours. Surface study motivation moderated the Impulsivity effect and achieving motivation the FFFS effect such that cheating was even more likely when high levels of these processes were used. CONCLUSIONS: The findings suggest that motivational personality traits defined within RST can explain variance in the likelihood of engaging in dishonest academic behaviours
