To explain the causes, I develop the so-called ＂perverse political accountability＂ approach. Specifically, the approach claims that a growing security challenge from China and North Korea, and US policy favoring Japan＇s foreign policy activism structure. Japan＇s domestic political condition that the majority of Japanese people become more conservative and nationalistic. Such shift in the Japanese people＇s preference has been both creating and reinforcing a perverse accountability by which the leaders or parties willing to adopt hard-line foreign policies are better off electorally while the leaders or parties remaining soft-line on foreign affairs are worse off. The perverse accountability not only leads to a severe partisan imbalance between the conservative parties and the leftist parties, but also gives the most conservative party, e.g., the Liberal Democratic Party （LDP）, a greater chance of coming to office and of pursuing assertive foreign policy they favor. Thus, the perverse accountability is at the center of current Japan＇s turn to foreign policy activism. This finding contributes to an enhanced understanding for Japan＇s shift to assertive foreign policy.展开更多

The story and character types remain the same; but the community can add their own jokes and commentary to make the play relevant to themselves and their community. What is added by the community says a lot about who they are and what they care about. The company Price-Waterhouse-Coopers produces their pantomime as management training and team building while engaging the community. The Basel Swiss panto raises money for African Charities. The Maplewood, NJ panto raises money for the homeless and the Jaguar Charity panto in Birmingham performs to disadvantaged children and adults. The productions can be extravagant or threadbare, but share the same goal of raising cheer and goodwill to the benefit of the community. What is it, then, about panto that brings a community together in such civic mindedness？展开更多

By doing so the author argues that while facebook and the Moroccan political arena are Male dominated public areas, young female activists have emerged as prominent leaders in both spaces. The author will more particularly explain why female and youth activists are important in the current state of Moroccan politics. Next, the author provides a discussion of the February 20th Movement, and the movement＇s utilization of Facebook. It will show that young female activists involved in the February 20th Movement have used Facebook in unique and creative ways to further the Movement.展开更多

As to media activism, there is a broad spectrum, including graffiti, radio activism, community media, visual activism, tactical media （Garcia ＆ Lovink, 1997）, and more recently, media interventions questioning the workings of biopower （Da Costa ＆ Philip, 2008）. On the other hand, debates on media competency and media literacy have been going on for a few decades. Although media have also been conceptualized as media of resistance or critique in informal contexts as well as in formal education, lively exchanges of concepts and ideas are comparatively seldom in respective traditions. The paper aims at exploring challenges for media education and interfaces between both fields.展开更多

Two subjects, the Hot Search List and its Public Discussion Forum, were chose to examine the complexity of the current situation of this hashtag activism. An auto-ethnographic methodology was used to interrogate the states quo of Chinese online feminist movement, revealing gender-centric discussions reinforcing stereotypes under the guise of equality. Misogynistic narratives, algorithmic constraints, censorship, and official opposition pose significant barriers to feminist discourse. Nonetheless, the study identifies a potential for hashtag activism within Weibo’s discourse, offering a space for resistance. By acknowledging these challenges, this paper seeks to empower Chinese feminists to challenge dominant narratives and advocate for their rights.展开更多

These studies explore how climate risk affects firms’ operating performance and leverage, stock and bond valuation, cost of capital, and managerial behavior. We also discuss how the effect of climate risk on real estate markets depends on individuals’ beliefs about climate change. Furthermore, we summarize papers on climate risk activism and how firms can employ financial devices and technology to mitigate their climate risk. Finally, we make some recommendations for further research areas.展开更多

This article presents an investigation into the role of mediatic sporting events and digital platforms in sparking political debate and social engagement to bring about change, including discussions on global and local interests and the performances of activist fans to promote debate on specific issues. The investigation employs a quantitative methodology. The initial inductive analysis uses a matrix of cultural key-frames of the empowerment and protest that accompany media sporting events, verifying their presence and effectiveness in different communication milieus. An analysis of the representation of protests on social media was performed through content analysis. The results of the investigation show that mediatic sporting events are to be understood as a diverse range of generators of multiple political effects: from the exercise of power to mass mobilization and media criticism.展开更多

文摘In historically, culturally, and technically variable media constellations, various forms of media activism, media education, and learning design have been developed. As to media activism, there is a broad spectrum, including graffiti, radio activism, community media, visual activism, tactical media （Garcia ＆ Lovink, 1997）, and more recently, media interventions questioning the workings of biopower （Da Costa ＆ Philip, 2008）. On the other hand, debates on media competency and media literacy have been going on for a few decades. Although media have also been conceptualized as media of resistance or critique in informal contexts as well as in formal education, lively exchanges of concepts and ideas are comparatively seldom in respective traditions. The paper aims at exploring challenges for media education and interfaces between both fields.

文摘This review focuses on major contemporary empirical studies that examine both the physical and regulatory sides of climate risk. These studies explore how climate risk affects firms’ operating performance and leverage, stock and bond valuation, cost of capital, and managerial behavior. We also discuss how the effect of climate risk on real estate markets depends on individuals’ beliefs about climate change. Furthermore, we summarize papers on climate risk activism and how firms can employ financial devices and technology to mitigate their climate risk. Finally, we make some recommendations for further research areas.

文摘Downregulation of the inwardly rectifying potassium channel Kir4.1 is a key step for inducing retinal Müller cell activation and interaction with other glial cells,which is involved in retinal ganglion cell apoptosis in glaucoma.Modulation of Kir4.1 expression in Müller cells may therefore be a potential strategy for attenuating retinal ganglion cell damage in glaucoma.In this study,we identified seven predicted phosphorylation sites in Kir4.1 and constructed lentiviral expression systems expressing Kir4.1 mutated at each site to prevent phosphorylation.Following this,we treated Müller glial cells in vitro and in vivo with the m Glu R I agonist DHPG to induce Kir4.1 or Kir4.1 Tyr^(9)Asp overexpression.We found that both Kir4.1 and Kir4.1 Tyr^(9)Asp overexpression inhibited activation of Müller glial cells.Subsequently,we established a rat model of chronic ocular hypertension by injecting microbeads into the anterior chamber and overexpressed Kir4.1 or Kir4.1 Tyr^(9)Asp in the eye,and observed similar results in Müller cells in vivo as those seen in vitro.Both Kir4.1 and Kir4.1 Tyr^(9)Asp overexpression inhibited Müller cell activation,regulated the balance of Bax/Bcl-2,and reduced the m RNA and protein levels of pro-inflammatory factors,including interleukin-1βand tumor necrosis factor-α.Furthermore,we investigated the regulatory effects of Kir4.1 and Kir4.1 Tyr^(9)Asp overexpression on the release of pro-inflammatory factors in a co-culture system of Müller glial cells and microglia.In this co-culture system,we observed elevated adenosine triphosphate concentrations in activated Müller cells,increased levels of translocator protein(a marker of microglial activation),and elevated interleukin-1βm RNA and protein levels in microglia induced by activated Müller cells.These changes could be reversed by Kir4.1 and Kir4.1 Tyr^(9)Asp overexpression in Müller cells.Kir4.1 overexpression,but not Kir4.1 Tyr^(9)Asp overexpression,reduced the number of proliferative and migratory microglia induced by activated Müller cells.Collectively,these results suggest that the tyrosine residue at position nine in Kir4.1 may serve as a functional modulation site in the retina in an experimental model of glaucoma.Kir4.1 and Kir4.1 Tyr^(9)Asp overexpression attenuated Müller cell activation,reduced ATP/P2X receptor–mediated interactions between glial cells,inhibited microglial activation,and decreased the synthesis and release of pro-inflammatory factors,consequently ameliorating retinal ganglion cell apoptosis in glaucoma.
文摘Lithium–sulfur(Li–S)batteries are promisingcandidates for next-generation energy storagegiven their high energy density and potential low cost.Chemically activated carbon(CAC)is often used fortheir cathodes,because it has a high specific surfacearea for sulfur loading.We have developed a pressurizedphysical activation(PPA)method that producedan activated carbon(PPAC)with a high specific surfacearea comparable to that of CAC.The pore structure of PPAC could be changed and its use as a cathode material for Li–Sbatteries was investigated.Battery tests at different capacity rates(C-rates)showed that it had a much improved high-rate performancewith a discharge capacity of 900 mAh/(g of sulfur)at 1 C,in contrast to only 600 mAh/(g of sulfur)for CAC.Porestructure analyses showed that PPAC prepared at a high activation temperature(1000℃)had unusual channel-like mesoporesbetween the microdomains that are the basic structural units of artificial carbon materials.These are connected to microporesdeveloped in each microdomain,and deliver ions from the surroundings to the internal pores and vice versa.The well-developedmicropores and mesopores of PPAC respectively ensured the high adsorption of lithium polysulfides and a high rate ofion diffusion.Compared to CAC,PPAC is a high-performance,low-cost cathode material that is promising for use in futureLi–S batteries.
文摘This paper reports the preparation of three di‑iron complexes containing a thiazole moiety.Esterification of complex[Fe_(2)(CO)_(6)(μ‑SCH_(2)CH(CH_(2)OH)S)](1)with 4‑methylthiazole‑5‑carboxylic acid gave the corresponding ester[Fe_(2)(CO)_(6)(μ‑tedt)](2),where tedt=SCH_(2)CH(CH_(2)OOC(5‑C_(3)HNSCH_(3)))S.Further reactions of complex 2 with tri(ptolyl)phosphine(tp)or tris(4‑fluorophenyl)phosphine(fp)gave the phosphine‑substituted derivatives[Fe_(2)(CO)_(5)(tp)(μ‑tedt)](3)and[Fe_(2)(CO)_(5)(fp)(μ‑tedt)](4).The structures of the newly prepared complexes were elucidated by elemental analysis,NMR,IR,and X‑ray photoelectron spectroscopy.Moreover,single‑crystal X‑ray diffraction analysis confirmed their molecular structures,showing that they contain a di‑iron core ligated by a bridged dithiolate bearing a thiazole moiety and terminal carbonyls.The electrochemical and electrocatalytic proton reduction were probed by cyclic voltammetry,revealing that three complexes can catalyze the reduction of protons to H_(2) under the electrochemical conditions.For comparison,complex 4 possessed the best efficiency with a turnover frequency of 23.5 s^(-1)at 10 mmol·L^(-1)HOAc concentration.In addition,the fungicidal activity of these complexes was also investigated in this study.CCDC:2477511,2;2477512,3;2477513,4.

文摘To elucidate the effect of calcite-regulated activated carbon(AC)structure on low-temperature denitrification performance of SCR catalysts,this work prepared a series of Mn-Ce/De-AC-xCaCO_(3)(x is the calcite content in coal)catalysts were prepared by the incipient wetness impregnation method,followed by acid washing to remove calcium-containing minerals.Comprehensive characterization and low-temperature denitrification tests revealed that calcite-induced structural modulation of coal-derived AC significantly enhances catalytic activity.Specifically,NO conversion increased from 88.3%of Mn-Ce/De-AC to 91.7%of Mn-Ce/De-AC-1CaCO_(3)(210℃).The improved SCR denitrification activity results from the enhancement of physicochemical properties including higher Mn^(4+)content and Ce^(4+)/Ce^(3+)ratio,an abundance of chemisorbed oxygen and acidic sites,which could strengthen the SCR reaction pathways(richer NH_(3)activated species and bidentate nitrate active species).Therefore,NO removal is enhanced.
