To respond to a touch, it is often necessary to localize it in space, and not just on the skin. The computation of this external spatial location involves the integration of somatosensation with visual and proprioceptive information about current body posture. In the past years, the study of touch localization has received substantial attention and has become a central topic in the research field of multisensory integration. In this review, we will explore important findings from this research, zooming in on one specific experimental paradigm, the temporal order judgment (TOJ) task, which has proven particularly fruitful for the investigation of tactile spatial processing. In a typical TOJ task participants perform non-speeded judgments about the order of two tactile stimuli presented in rapid succession to different skin sites. This task could be solved without relying on external spatial coordinates. However, postural manipulations affect TOJ performance, indicating that external coordinates are in fact computed automatically. We show that this makes the TOJ task a reliable indicator of spatial remapping, and provide an overview over the versatile analysis options for TOJ. We introduce current theories of TOJ and touch localization, and then relate TOJ to behavioral and electrophysiological evidence from other paradigms, probing the benefit of TOJ for the study of spatial processing as well as related topics such as multisensory plasticity, body processing, and pain.
Thirdly, similarity judgments of participants will be assessed by both categorical measurement (i.e., overt preferences) and continuous measurement (i.e., RT). The former variable can only answer the dichotomous question of whether language influences non-verbal cognition (i.e., A or B in a forced similarity judgment task), whilst the latter variable allows us to test the degree of differences (if any) in behavior as engendered by language differences. Given the fact that the two languages under investigation are only partially different (rather than entirely opposing), there is a third likelihood, in which the proportion of overt preferences for manner (or path) might not vary significantly across types of participants; any language-biased patterns in behavior will only be evident (if at all) when examined under the lens of RT.
As mentioned earlier, the two-way mixed ANOVA confirmed that, generally, English speakers were significantly quicker in responding to motion stimuli in their similarity judgments, as compared to all other four groups (i.e., the main effect of group). A closer examination of the dataset via multiple comparisons with Bonferroni correction further revealed that in making manner-matched choices, monolingual speakers of English were significantly quicker than their Chinese peers (mean difference = -670, p = 0.008), as well as the three L2 groups (ENNS vs. L2-low: mean difference = -897, p < 0.001; ENNS vs. L2-Medium: mean difference = -555, p = 0.052, and ENNS vs. L2-High: mean difference = -710, p = 0.004). By contrast, in opting for path-matched motion scenes, monolingual speakers of English did not differ significantly from their Chinese counterparts (mean difference = -464, ns), though they still reacted quicker as compared to the learner groups (ENNS vs. L2-low: mean difference = -659, p = 0.001; ENNS vs. L2-Medium: mean difference = -559, p = 0.012, and ENNS vs. L2-High: mean difference = -868, p < 0.001). Such a contrast in RT between the two groups of monolingual speakers is of particular importance in indicating that the overall quicker RT of English monolinguals can be attributed to their even quicker reaction to manner-matches.
The above discussions highlight the importance of introducing the RT data into our analysis: they may be more sensitive to language effects that are too probabilistic to detect in the choice response in a forced similarity judgment context. In hindsight, the adoption of RT in measuring the implicit processing in similarity judgments is particularly useful to our study. Overt choices (i.e., manner- or path-match) reveal information about what decisions participants make, and how often they make it, whilst the RT provides information about the speed with which participants render a judgment. Given that the two sets of measurements produce findings that are inconsistent with each other, the RT data aids us in revealing aspects of processing that are not readily available in choice results.
The judgment marks the conclusion of the last case relating to core crimes that the Mechanism inherited from the International Criminal Tribunal for the former Yugoslavia, which, as you will recall, was established in 1993 to prosecute persons responsible for serious violations of international humanitarian law committed in the territory of the former Yugoslavia since 1991.
For this year alone, we and our humanitarian partners have reached nearly 3 million people with emergency health services and medicines and plans to reach 8 million by the end of this year. Today, we delivered enough medicine to treat some 2,000 civilians remaining in the community of Preobrazhenka, just 5 kilometres from the frontline of the Zaporizhzhia region.
Quick update from Myanmar and our response to Cyclone Mocha, not too long ago: Two weeks after the cyclone hit, we and our partners have distributed shelter and other relief items to more than 63,000 people and over 230,000 people have received some food assistance.
Ms. Zarkan added that the traditional approach of disarmament and arms control diplomacy - looking at objects or capabilities and putting qualitative and quantitative controls on systems to remove the need for competition - was not exclusive. The other way to look at the factors of the arms race was to observe the behaviours or actions of different parties which could exacerbate tensions. The stakes were very high in space, in part because of the nature of the space environment and the potential consequences of errors of judgement, because objects were out of range once launched. Without increased transparency about space objects and their missions, it would be difficult to dispel perceptions about the threats these co-orbital devices or anti-satellite tests might pose. To conclude, in terms of space, it had emerged from the discussions that thinking about the future of the safety and security of operations was more than necessary.
Mr. Spies then turned to the characterisation of actions and activities that could be considered responsible, irresponsible, or threatening, and their potential impact on international security. While submissions provided a robust set of examples for responsible and irresponsible behaviours, it should also be noted that some expressed concern about the possibility for subjective judgment in attempting to distinguish between the two. Examples of responsible behaviours included, inter alia: avoiding surprising or provocative actions; communicating in advance of high-risk operations; and refraining from deliberate and non-consensual interference. On the other hand, examples of irresponsible or threating actions and activities included, inter alia: development, testing, deployment, use of counter-space capabilities or the use of a space object to attack a terrestrial target; and operations that interfered with space systems, including military and situational awareness systems. As regards approaches to the development of norms, rules, and principles, many expressed support for a behaviour-based approach. It was considered that such an approach could lead to a legal instrument or be pursued in tandem. There was also support for continuing the traditional approach for preventing an arms race in outer space. The submissions reflected a rich menu of elements that could form the basis for norms, rules, and principles of responsible behaviour, such as: affirming the applicability of international law; debris mitigation; and restrictions on various forms of intentional electromagnetic interference.
It is suggested that alternative dispute resolution (ADR) has a significant role to play in resolving outer space disputes, particularly through the auspices of the investor-state dispute settlement (ISDS) framework, as well as via the adoption of mandatory arbitration and mediation referral powers involving private enterprises.
Notably, the UN Convention on Registration of Objects Launched into Outer Space, which entered into force in 1976, requires signatory States to establish their own national registries and to impose obligations on all parties that launch an object into outer space to register those objects on the locally-established outer space register. The records on the locally-established registers are then collated and included in the global UN Register of Objects Launched into Outer Space. For example, in Australia, the Space (Launches and Returns) Act 2018 (Cth) sets up a regulatory regime for space activities originating in Australia, including the need for approval to launch a space object from Australia and the need to register all space objects so approved.
To enhance the uptake of arbitration to resolve outer space commercial disputes, it is worth considering mandatory referral powers as part of a recast international space treaty. States could be required to implement those referral powers by way of registration preconditions under their local outer space registries established under the enabling legislation discussed earlier in this article.22
The establishment of the Court of Space is intended by the DIFC to reflect the progress the United Arab Emirates (UAE) as a whole has made in commercial outer space activities in the last decade, with the UAE now recognised as one of the most active countries in the world in space exploration. As part of the Court of Space initiative, there will also be specific guidelines to encourage out of court settlements of space disputes, as well as a dedicated training program for specialist judges to develop advanced knowledge and experience in space-specific technical issues and disputes.
