Intermediate Vector

In this last chapter, some scientific discoveries are described in which calorimeters have played a crucial role. The chosen examples were all awarded a Nobel prize in physics. The first example concerns the discovery of the intermediate vector bosons (W and Z) by the experiments UA1 and UA2 at CERN (1982). More than anything else, this discovery has been crucial for the dominant role that calorimeters have played in the design of experiments at the subsequent generation(s) of particle accelerators. The second example concerns the discovery of the fact that neutrinos have a non-zero rest mass, by the SuperKamiokande collaboration (1998). This discovery inspired the development of the even larger water Cerenkov calorimeters discussed in Chapter 10. The third example concerns the discovery of the Higgs boson, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider (2012). In all three cases, the role of the calorimeters, and their importance for the discoveries, is described in some detail.

This article examines how objects embedded in the domestic life of the generation of the Lebanese civil war and the subsequent generations evoke stories that disrupt the state�s hegemonic production of history. The article explores stories surrounding two objects that survived the war, and took on residues of memory later heard and retold by the subsequent generation. These objects illuminate ways in which the legacy of intergenerational memory is produced and transmitted�and how these alternative spaces and stories emerge in present struggles, including the October 2019 revolution. In the first section, the article examines how material objects operate as intergenerational symbols of the experiences of war and as media for the process of narrativisation. In the second section, the argument explores the role of the material as a witness to what resists language and as a locus to memory�s temporality. In the third section, the article looks into the affective dimension of the material object as it provokes an opening to narration and challenges linear understandings of history. This search through material and domestic objects seeks stories that resist closure, and is essential to understanding today�s struggle against the Lebanese political class.

From general advertising tasks and strategies three hypotheses about connectivity in advertisement texts were derived: 1. In advertisements the number of connectors will be comparatively high. 2. The number of subordinating connectors, however, will be low. 3. Connectors which semantically possess an argumentative or rhetoric quality will play a dominant role. These hypotheses were tested in a comparative study of written advertising language and other kinds of written texts. Hypothesis 1 and 2 were supported. In testing the third hypothesis it was found that the connectors of addition and of causation are more frequent in advertising than in other written language, but that adversatives are not. In a qualitative analysis the role of causal relationships was worked out. It was found that their functions fitted the tasks of advertising texts from which the hypotheses originated very well. At least five functions have been found: 1. Causal connectors often relate two different product qualities to each other. 2. They do this by putting these qualities in an argumentative structure of the following form: Product quality (P) conclusion> General positive quality (C) or: Ρ explanation 3. When the generalizing difference between (P) and (C) is not very strong, the structure becomes one of tautological repetition. In this way a product quality may be accentuated.

The Third World

There is something seriously flawed about models of social change that posit the dominant role of in-built civilizational motors. While “the rise of the West” makes great ideology, it is poor history. Like Jared Diamond, I believe that we need to situate the fate of nations in a long-term ecohistorical context. Unlike Diamond, I believe that the ways (and the sequences) in which things happened mattered deeply to what came next. The Mediterranean is a particularly useful case in this light. No longer a center of progress after the sixteenth century, the decline of the Mediterranean is usually ascribed to its inherent cultural deficiencies. While the specific cultural infirmity varies with the historian (amoral familism, patron/clientalism, and religion are some of the favorites) its civilizationalist presuppositions are clear. In this respect the search for “what went wrong” typifies national histories across the region and prefigures the fate of the Third World.

AbstractVery recently, the LHCb Collaboration at the Large Hadron Collider at CERN observed new resonance X(4630). The X(4630) is decoded as a charmoniumlike molecule with hidden-strange quantum number well in the one-boson-exchange mechanism. Especially, the study of its hidden-charmed decays explicitly shows the dominant role of $$J/\psi \phi $$ J / ψ ϕ among all allowed hidden-charmed decays of the X(4630), which enforces the conclusion of X(4630) as a charmoniumlike molecule. The discovery of the X(4630) is a crucial step of constructing charmoniumlike molecule zoo.

We discuss the U (1)X extensions of the standard model with focus on the Stueckelberg mechanism for mass growth for the extra U (1)X gauge boson. The assumption of an axionic connector field which carries dual U(1) quantum numbers, i.e. quantum numbers for the hypercharge U(1) Y and for the hidden sector gauge group U (1)X, allows a nontrivial mixing between the mass growth for the neutral gauge vector bosons in the SU(2) L × U (1)Y sector and the mass growth for the vector boson by the Stueckelberg mechanism in the U (1)X sector. This results in an extra Z′ which can be very narrow, but still detectable at the Large Hadron Collider (LHC). The U (1)X extension of the minimal supersymmetric standard model is also considered and the role of the Fayet–Illiopoulos term in such an extension discussed. The U (1)X extensions of the SM and of the MSSM lead to new candidates for dark matter.

This chapter analyses the contribution of slave labour to Athens’ citizenry during the classical period. It shows how slaves were distributed across the wealth spectrum and the role of market exchange in providing ready access to slaves at low prices. The second part of the chapter analyses the contribution of slave labour to the liturgical class and shows that although slavery was indispensable to elite income, it played a less dominant role for the Athenian elite than for the Spartan elite. The third part of the chapter explores sub-elite slave ownership, and provides a critique of E. M. Wood’s view that slaves played little role in sub-elite agriculture.

Abstract Scientific findings have indicated that psychological and social factors are the driving forces behind most chronic benign pain presentations, especially in a claim context, and are relevant to at least three of the AMA Guides publications: AMA Guides to Evaluation of Disease and Injury Causation, AMA Guides to Work Ability and Return to Work, and AMA Guides to the Evaluation of Permanent Impairment. The author reviews and summarizes studies that have identified the dominant role of financial, psychological, and other non–general medicine factors in patients who report low back pain. For example, one meta-analysis found that compensation results in an increase in pain perception and a reduction in the ability to benefit from medical and psychological treatment. Other studies have found a correlation between the level of compensation and health outcomes (greater compensation is associated with worse outcomes), and legal systems that discourage compensation for pain produce better health outcomes. One study found that, among persons with carpal tunnel syndrome, claimants had worse outcomes than nonclaimants despite receiving more treatment; another examined the problematic relationship between complex regional pain syndrome (CRPS) and compensation and found that cases of CRPS are dominated by legal claims, a disparity that highlights the dominant role of compensation. Workers’ compensation claimants are almost never evaluated for personality disorders or mental illness. The article concludes with recommendations that evaluators can consider in individual cases.

This article sheds light on the role of grammar in understanding legislative texts, with reference to the wuḍūʾ verse (Q. 5:6). The first section deals with the issue of washing the elbows along with the feet as part of ritual ablution, and lists the various interpretations of the preposition ilā in the aya, and discusses the grammatical theory used by different fuqahāʾ to support their arguments. The second section tackles how much of the head should be rubbed in ritual ablution, with regard to the use of the preposition bi- in the phrase bi-ruʾūsikum, while the third focuses on the two readings of the phrase arjulakum/arjulikum (‘your feet’) and on passing legislative judgement on whether the feet be washed or just rubbed. The study concludes that lugha and fiqh theory are of mutual importance and together help to clarify legislative judgements, and, on this basis, that jurists should not pass any legislative judgement without referring to language.

The objectives of this qualitative research were (1) to identify the factors that affect the Minangkabau language (ML) maintenance in Medan, (2) to discover the parents’ efforts in maintaining ML in Medan and (3) to find out the reason why the speakers have to maintain ML. The souree of data is the nembers of the Association of Sei Jaring Community (Ikatan Warga Sei Jaring: IWS) in Medan. The sample was 10 families including 10 parents and their children. The instruments of this study are a questionnaire and an interview. The questionnaire was used to answer the factors affected the maintenance of ML and how factors affected the maintenance of ML. The interview was used to discover the influence why Minangkabau’s people have to maintain ML. There are four factors in ML maintenance, the parents’ role, the role of family, the intramarriage and homeland visits. After distributing questionnaire and did some interviews it is found that IWS especially for the third generation (children) has the danger level in ML when they communicate to each other. Meanwhile, the data analysis also shows that both fathers and mothers communicate to each other with ML. This condition occurred because of the influence of the environment. Parents have to keep communication and teaching Minangkabau language continuously to their children. so, the young generation can keep the existence of ML for their future. Keywords: Minangkabau Language Maintenance, parents’ efforts, the young generation.

Zakat is an important form of religiously mandated charity under Islam. It is the third pillar of Islam. The giving of Zakat is important for Muslims, as this leads to purification of their wealth from all sins. This paper examines the role of Zakat as an instrument of social justice and poverty eradication in society. Each Muslim calculates his or her own Zakat individually. Generally, this involves the payment each year of two and a half percent of one's capital, after the needs of the family have been met. One can donate additional amount as an act of voluntary charity but Zakat is fundamental to every Muslim. Zakat is the Islamic contribution to social justice: those who have to give charity share the benefit of their prosperity to those who have fallen short. This is the Islamic approach to remove greed and envy and to purify one's soul based on good intentions. This is the institution of Zakat in Islam. The institution of Zakat serves to eradicate poverty in the community and uphold the light of Islam. Allah says “whatever is paid as Zakat for the sake of Allah shall be rewarded in manifolds”.
