Ethical food packaging and designed encounters with distant and exotic others

There has been criticism of how Fair-Trade products represent workers in remote parts of the world where packaging offers an encounter with distant others which romanticizes and homogenizes them as a pre-modern form of ethnicity. Such workers are shown as always engaged in authentic, simple, honest decontextualized manual labour. And they are depicted as highly appreciative of, and empowered by, the act of ethical shopping. This paper shows that a close social semiotic analysis of Fair-Trade packaging reveals a different set of meanings which sit alongside the decontextualized ones. Designs integrate these workers into more contemporary kinds of modernist, rational, design chic, which communicates its own kind of honesty and authenticity. We consider how this, too, shapes how such consumers encounter distant others and its consequence for the meaning of the act of ethical shopping, where consumers can buy into moral alignment offered by products

P4_5 Atmospheric ODSTs

In this paper the maximum acceleration on the ODST and the pod was found to be $-4g$, with a braking thrusters force of $14100$ N during the last $50$ m of descent. This deceleration brings the impact velocity of the pod to below velocity of $1$ ms$^{-1}$, should the braking thrusters fail to fire the pod will hit the ground with a velocity of $43.2$ ms$^{-1}$ killing the trooper

P4_4 Snorlax used Body Slam

In this paper we consider the maximum strength of Ash's Snorlax, from the Pokemon original TV series, this will occur when the Snorlax jumps as high as it can. The maximum height of the jump was calculated to be 41.8 m, the velocity it impacts the ground with is 28.1 ms^-1 and the momentum of the Snorlax when it hits the ground is 12,900 kgms^-1

Psychological consequences of childhood obesity: psychiatric comorbidity and prevention

Childhood obesity is one of the most serious public health challenges of the 21st century with far-reaching and enduring adverse consequences for health outcomes. Over 42 million children <5 years worldwide are estimated to be overweight (OW) or obese (OB), and if current trends continue, then an estimated 70 million children will be OW or OB by 2025. The purpose of this review was to focus on psychiatric, psychological, and psychosocial consequences of childhood obesity (OBy) to include a broad range of international studies. The aim was to establish what has recently changed in relation to the common psychological consequences associated with childhood OBy. A systematic search was conducted in MEDLINE, Web of Science, and the Cochrane Library for articles presenting information on the identification or prevention of psychiatric morbidity in childhood obesity. Relevant data were extracted and narratively reviewed. Findings established childhood OW/OBy was negatively associated with psychological comorbidities, such as depression, poorer perceived lower scores on health-related quality of life, emotional and behavioral disorders, and self-esteem during childhood. Evidence related to the association between attention-deficit/hyperactivity disorder (ADHD) and OBy remains unconvincing because of various findings from studies. OW children were more likely to experience multiple associated psychosocial problems than their healthy-weight peers, which may be adversely influenced by OBy stigma, teasing, and bullying. OBy stigma, teasing, and bullying are pervasive and can have serious consequences for emotional and physical health and performance. It remains unclear as to whether psychiatric disorders and psychological problems are a cause or a consequence of childhood obesity or whether common factors promote both obesity and psychiatric disturbances in susceptible children and adolescents. A cohesive and strategic approach to tackle this current obesity epidemic is necessary to combat this increasing trend which is compromising the health and well-being of the young generation and seriously impinging on resources and economic costs

P4_2 How to fly your dragon

In this paper we calculate the minimum area and length of a dragon’s wing for it to be able to fly. The minimum area was calculated to be 224m^2 and the length was 35.6m

P4_3 Light Ordnance

In this paper we consider a weapon system that fires a laser at an interplanetary vessel. We calculate the energy required to melt through a vessel’s armoured hull, of thickness 0.254 m, from a shot from a laser with a calibre of 16 inches. The energy required is found to be E = 34449 J. Using this energy, the recoil of the laser firing was calculated to be ρ = 1.15x10−4 kgms−1

P4_6 Wind swept

This paper discusses the plausibility of the thruster in the Iron Man suit being used as weapons to push a human back. It was determined that the shock-wave produced by the change in temperature due to the thrusters would produce a force of $183$ kN on a person it was shot at, this would cause the person to accelerate at $2614$ ms$^{-2}$ killing the person

Mitochondrial ROS cause motor deficits induced by synaptic inactivity:implications for synapse pruning

Developmental synapse pruning refines burgeoning connectomes. The basic mechanisms of mitochondrial reactive oxygen species (ROS) production suggest they select inactive synapses for pruning: whether they do so is unknown. To begin to unravel whether mitochondrial ROS regulate pruning, we made the local consequences of neuromuscular junction (NMJ) pruning detectable as motor deficits by using disparate exogenous and endogenous models to induce synaptic inactivity en masse in developing Xenopus laevis tadpoles. We resolved whether: (1) synaptic inactivity increases mitochondrial ROS; and (2) antioxidants rescue synaptic inactivity induced motor deficits. Regardless of whether it was achieved with muscle (α-bugarotoxin), nerve (α-latrotoxin) targeted neurotoxins or an endogenous pruning cue (SPARC), synaptic inactivity increased mitochondrial ROS in vivo. The manganese porphyrins MnTE-2-PyP5+ and/or MnTnBuOE-2-PyP5+ blocked mitochondrial ROS to significantly reduce neurotoxin and endogenous pruning cue induced motor deficits. Selectively inducing mitochondrial ROS—using mitochondria-targeted Paraquat (MitoPQ)—recapitulated synaptic inactivity induced motor deficits; which were significantly reduced by blocking mitochondrial ROS with MnTnBuOE-2-PyP5+. We unveil mitochondrial ROS as synaptic activity sentinels that regulate the phenotypical consequences of forced synaptic inactivity at the NMJ. Our novel results are relevant to pruning because synaptic inactivity is one of its defining features

Biosemiotics, politics and Th.A. Sebeok’s move from linguistics to semiotics

This paper will focus on the political implications for the language sciences of Sebeok’s move from linguistics to a global semiotic perspective, a move that ultimately resulted in biosemiotics. The paper will seek to make more explicit the political bearing of a biosemiotic perspective in the language sciences and the human sciences in general. In particular, it will discuss the definition of language inherent in Sebeok’s project and the fundamental re-drawing of the grounds of linguistic debate heralded by Sebeok’s embrace of the concept of modelling. Thus far, the political co-ordinates of the biosemiotic project have not really been made explicit. This paper will therefore seek to outline 1. how biosemiotics enables us to reconfigure our understanding of the role of language in culture; 2. how exaptation is central to the evolution of language and communication, rather than adaptation; 3. how communication is the key issue in biosphere, rather than language, not just because communication includes language but because the language sciences often refer to language as if it were mere “chatter”, “tropes” and “figures of speech”; 4. how biosemiotics, despite its seeming “neutrality” arising from its transdisciplinarity, is thoroughly political; 5. how the failure to see the implications of the move from linguistics to semiotics arises from the fact that biosemiotics is devoid of old style politics, which is based on representation (devoid of experience) and “construction of [everything] in discourse” (which is grounded in linguistics, not communication study). In contrast to the post-“linguistic turn” idea that the world is “constructed in discourse”, we will argue that biosemiotics entails a reconfiguration of the polis and, in particular, offers the chance to completely reconceptualise ideology
