Suji Kwock Kim's “Generation” and the Ethics of Diasporic Postmemory

Regarding her highly acclaimed first book of poetry, Notes from the Divided Country, second-generation Korean American poet Suji Kwock Kim has stated that she considers the representation of the traumatic experiences of the Korean War as “the responsibility that one has, in terms of using the imagination as a means of compassion, and understanding things one couldn't have experienced.” If Notes from the Divided Country is a work created from a sense of ethical responsibility, we could perhaps also see it more specifically as a project of ethical memory and ask, along with ethnic studies scholar Jodi Kim, “What does it mean to want to represent or ‘remember’ a war that has been ‘forgotten’ and erased in the U.S. popular imaginary, but has been transgenerationally seared into the memories of Koreans and Korean Americans, and experienced anew every day in a still-divided Korea?” Notes from the Divided Country in many ways grapples with this very question and can be seen as an effort to remember the “Forgotten War” through vivid, chilling, moving poems that depict the enduring trauma of wartime violence from the perspective of diasporic postmemory. Taking Hirsch's work on Holocaust photos as a point of departure, this article reads in the poem “Generation” the poetics of postmemory and the ethics of memory from the perspective of diasporic subjectivity

Redefining Diaspora through a Phenomenology of Postmemory

This article seeks to intervene in the debates about the definition of diaspora by attending to the way in which it is a phenomenon, rooted in a particular kind of experience and consciousness. This approach seeks to move beyond ontological definitions based on categorical criteria toward a more phenomenological definition that can help us better understand the lived experience of diasporic subjects and the formation of diasporic communities. While these groups do not exist as entities that have some common essence or nature, I insist that they do exist phenomonologically. Rather than an objective, prescriptive definition of diaspora, this essay explores the subjective, descriptive quality of diaspora when approached from the inside, as an experience. A phenomenological approach, therefore, can rescue the term diaspora from its overextensions and case-specific limitations. A key consideration will be the role of memory in creating the phenomenon of diaspora. Diaspora must be understood as a phenomenon that emerges when displaced subjects who experience the loss of an "origin" (whether literal or symbolic) perpetuate identifications associated with those places of origin in subsequent generations through the mechanisms of postmemory

Workplace violence and the effect of the working environment and social support within a human service organisation : a thesis presented to Massey University in partial fulfillment of the requirements for the degree of Master of Science in Psychology

At the present time, there is an increasing awareness of the risk of workplace violence that certain occupational groups face within their professions. This study investigated violence within a human service organisation responsible for looking after profoundly intellectually handicapped individuals with little chance of being mainstreamed into normal society. Three hundred and forty three employees responded to a questionnaire about incidents of violence encountered at work, stressors within their job, and their perceptions of social support and the work environment. The hypotheses were (1) that symptoms of stress and traumatic stress increase in frequency and intensity following involvement in a violent incident, and will be cumulative and additive following repetitive exposure (2) that positive perceptions of the working environment decrease the symptoms of stress and traumatic stress ; and (3) that higher perceptions of the effectiveness of social support decrease the symptoms of stress and traumatic stress. The results showed that violence affected employees mentally, emotionally and physically. Perceptions of the work environment was found to have an effect on responses to violence but social support was not. Recommendations made included reducing violence by redesigning the physical environment, or the use of training to help with stress management. These results could help with the investigation of violence within the health care field

Effects of Sex and Gender on Adaptation to Space: Musculoskeletal Health

There is considerable variability among individuals in musculoskeletal response to long-duration spaceflight. The specific origin of the individual variability is unknown but is almost certainly influenced by the details of other mission conditions such as individual differences in exercise countermeasures, particularly intensity of exercise, dietary intake, medication use, stress, sleep, psychological profiles, and actual mission task demands. In addition to variations in mission conditions, genetic differences may account for some aspect of individual variability. Generally, this individual variability exceeds the variability between sexes that adds to the complexity of understanding sex differences alone. Research specifically related to sex differences of the musculoskeletal system during unloading is presented and discussed

Korean Han and the Postcolonial Afterlives of "The Beauty of Sorrow"

In this article, I depart from the typical discussion of the Korean sociocultural concept of han as a collective feeling of unresolved resentment, pain, grief, and anger that runs in the blood of all Koreans. Scholars, artists, writers, and critics frequently characterize han as "the Korean ethos" and the soul of Korean art, literature, and film. It is said to be unique to Koreans and incomprehensible to Westerners. I argue, however, that its contemporary biologistic-oriented meaning emerged first during the Japanese colonial period as a colonial stereotype, and that tracing the afterlife of han gives us a postcolonial understanding of its deployment in culture. I examine how han originated under the contradictions of coloniality, how it evolved from a colonial construct to its adoption into Korean ethnonationalism, and how it travels into a completely new context through the Korean diaspora. Rather than dismissing han as nothing more than a social construct, I instead define han as an affect that encapsulates the grief of historical memory—the memory of past collective trauma—and that renders itself racialized/ethnicized and attached to nation

Source signatures from combined isotopic analyses of PM2.5 carbonaceous and nitrogen aerosols at the peri-urban Taehwa Research Forest, South Korea in summer and fall.

Isotopes are essential tools to apportion major sources of aerosols. We measured the radiocarbon, stable carbon, and stable nitrogen isotopic composition of PM2.5 at Taehwa Research Forest (TRF) near Seoul Metropolitan Area (SMA) during August-October 2014. PM2.5, TC, and TN concentrations were 19.4 ± 10.1 μg m-3, 2.6 ± 0.8 μg C m-3, and 1.4 ± 1.4 μg N m-3, respectively. The δ13C of TC and the δ15N of TN were - 25.4 ± 0.7‰ and 14.6 ± 3.8‰, respectively. EC was dominated by fossil-fuel sources with Fff (EC) of 78 ± 7%. In contrast, contemporary sources were dominant for TC with Fc (TC) of 76 ± 7%, revealing the significant contribution of contemporary sources to OC during the growing season. The isotopic signature carries more detailed information on sources depending on air mass trajectories. The urban influence was dominant under stagnant condition, which was in reasonable agreement with the estimated δ15N of NH4+. The low δ15N (7.0 ± 0.2‰) with high TN concentration was apparent in air masses from Shandong province, indicating fossil fuel combustion as major emission source. In contrast, the high δ15N (16.1 ± 3.2‰) with enhanced TC/TN ratio reveals the impact of biomass burning in the air transported from the far eastern border region of China and Russia. Our findings highlight that the multi-isotopic composition is a useful tool to identify emission sources and to trace regional sources of carbonaceous and nitrogen aerosols

Effects of candesartan, an angiotensin II receptor type I blocker, on atrial remodeling in spontaneously hypertensive rats

Hypertension-induced structural remodeling of the left atrium (LA) has been suggested to involve the renin–angiotensin system. This study investigated whether treatment with an angiotensin receptor blocker, candesartan, regresses atrial remodeling in spontaneously hypertensive rats (SHR). Effects of treatment with candesartan were compared to treatment with a nonspecific vasodilatator, hydralazine. Thirty to 32-week-old adult male SHR were either untreated (n = 15) or received one of either candesartan cilexetil (n = 9; 3 mg/kg/day) or hydralazine (n = 10; 14 mg/kg/day) via their drinking water for 14 weeks prior to experiments. Untreated age- and sex-matched Wistar- Kyoto rats (WKY; n = 13) represented a normotensive control group. Untreated SHR were hypertensive, with left ventricular hypertrophy (LVH) compared to WKY, but there were no differences in systolic pressures in excised, perfused hearts. LA from SHR were hypertrophied and showed increased fibrosis compared to those from WKY, but there was no change in connexin-43 expression or phosphorylation. Treatment with candesartan reduced systolic tail artery pressures of conscious SHR below those of normotensive WKY and caused regression of both LVH and LA hypertrophy. Although hydralazine reduced SHR arterial pressures to those of WKY and led to regression of LA hypertrophy, it had no significant effect on LVH. Notably, LA fibrosis was unaffected by treatment with either agent. These data show that candesartan, at a dose sufficient to reduce blood pressure and LVH, did not cause regression of LA fibrosis in hypertensive rats. On the other hand, the data also suggest that normalization of arterial pressure can lead to the regression of LA hypertrophy

Generic Qualitative Research in Psychology

Some topics for qualitative research in psychology are unsuitable for or cannot be adapted to the traditional qualitative designs such as case study, ethnography, grounded theory, or phenomenology. This paper explores reasons for this, and proposes that psychological researchers can use a generic qualitative design in such situations. After discussing the types of topics most suitable for a generic qualitative design, the paper differentiates generic qualitative designs from the more traditional qualitative designs, with particular attention to how generic qualitative inquiry differs from phenomenological psychological research. Finally, appropriate procedures for data collection and for thematic data analysis in a generic model are discussed and described in detail

Development of q-PCR approaches to assess water quality: Effects of cadmium on gene expression of the diatom Eolimna minima

This study was undertaken to develop molecular tools to assess water quality using diatoms as the biological model. Molecular approaches were designed following the development of a rapid and easy RNA extraction method suited to diatoms and the sequencing of genes involved in mitochondrial and photosystem metabolism. Secondly the impact of cadmium was evaluated at the genetic level by q-PCR on 9 genes of interest after exposure of Eolimna minima diatom populations cultured in suspension under controlled laboratory conditions. Their growth kinetics and Cd bioaccumulation were followed.Population growth rates revealed the high impact of Cd at 100μg/L with total inhibition of growth. These results are linked to the high bioaccumulation values calculated after 14 days of exposure, 57.0±6.3μg. Cd/g. dw and 734.1±70μg. Cd/g. dw for exposures of 10 and 100μg. Cd/L respectively.Genetic responses revealed the impact of Cd on the mitochondrial metabolism and the chloroplast photosystem of E. minima exposed to 10 and 100μg. Cd/L with induction of cox1, 12S, d1 and psaA after 7 days of exposure for the concentration of 100μg. Cd/L and of nad5, d1 and psaA after 14 days of exposure for both conditions.This is the first reported use of q-PCR for the assessment of toxic pollution on benthic river diatoms. The results obtained presage interesting perspectives, but the techniques developed need to be optimized before the design of new water quality diagnosis tools for use on natural biofilms

Use of superabsorbent polymers to mitigate autogenous shrinkage in ultra-high performance concrete

Ultra-high performance concrete (UHPC) with low w/c-ratio is very prone to the formation of cracks due to autogenous shrinkage. These cracks can lead to a decreased durability of the concrete, resulting in higher maintenance and/or repair costs in the future. Superabsorbent polymers (SAPs) can be added to cementitious materials to provide internal curing and as a result reduce or even mitigate this autogenous shrinkage. In this paper, two different types of SAPs were added to cement paste to see their influence on mitigating autogenous shrinkage. One SAP is a commercially available SAP whereas the other SAP is especially developed within the framework of the LORCENIS project by the company ChemStream, with the aim to mitigate autogenous shrinkage and induce self-healing of cracks. The SAPs from ChemStream were based on a copolymerization of sodium vinyl sulfonate (SVS) with 2-acryloylamino-2-methyl-propane-1-sulfonate (NaAMPS) and contained 1.0 mol% N,N’-methylenebisacrylamide (MBA) with respect to the monomer as cross-linker. The commercial SAP from BASF was based on poly(acrylamide-co-acrylic acid). In case SAPs were used, an additional fixed amount of water was added to mitigate autogenous shrinkage. The amount of SAPs used was determined based on their swelling capacity in cement filtrate and in order to obtain the same workability as the reference mixture. The amount of SAPs needed was in the range of 0.2-0.26 m% of the cement weight. To see whether the size of the SAPs plays a role in the efficiency of mitigating autogenous shrinkage, two average particle sizes, namely 40 and 100 µm, were tested. With the used amount of SAPs, a reduction or even complete counteraction of autogenous shrinkage was observed for the cement pastes
