Guidelines for better writing
Basic principles
Clear writing starts with clear
thinking
• Before you start writing, ask: “What am I trying to say?”
• When you finish writing, ask:
“Have I said it?”
Basic principles
• Bullet point list of main ideas
– each idea will become a single paragraph – ideas should be formulated as simple declarative
statements: these will be the topic sentences of your paragraphs
– organize your ideas into sections
Planning is key

(Olshtain and Cohen, 1983), later extended to identifying a speech-act specific‘sociopragmatic set’ of social and contextual factors (Olshtain, 1989; Olshtainand Weinbach, 1987). She further contends that only rarely have researchersworking on the apology as a speech act set out to explain its form and strategicfunctions in terms of underlying cultural attitudes, though some more recentwork has attempted to do this (see Luke, 1997; Marquez Reiter, 2000; Meyerhoff,1999; Obeng, 1999; Okumura and Wei, 2000; Suszczynska,1999).
Several other factors emerge from Meier’s review. First, research on theapology as a speech act has been very much focused on the interpersonal andinteractive behaviour of individuals in mainly informal situations. That is,someone apologizes to someone else for an ‘offence’ usually caused by actions,including other speech acts, which in some way violate a social or cultural normand which are often associated with impoliteness or rudeness. There is relativelylittle work on ‘public’ apologies, either within institutional or other professionalcontexts. Meier’s review makes no reference to political apologies (but see Meier,2004). Second, though there is some discernible agreement as to whatconstitutes an apology in terms of its component parts in a very general sense,the actual taxonomies produced by a wide range of studies ‘contain significantvariations both in their number of categories and in category types and theiroperationalisation’ (1998: 222). How an apology is defined is greatly influencedby disciplinary perspectives, emphasis and the scope of the particular researchstudy. To the extent that many such definitions and taxonomies are explicitlygrounded in specific linguistic and cultural contexts, their relevance to the studyof political apologies is perhaps less tangential than one might expect. Though itis unlikely ever to be possible to determine explicitly and comprehensively aspeech act set of the major semantic formulas for apologizing which will apply inall contexts, languages, and cultures, Meier (1998: 226) argues that ‘this doesnot undermine the value of such research’, but rather suggests that ‘its majorvalue may not lie in uncovering set patterns or norms of linguistic behavior’ andinstead that the goals themselves need to be extended.
Third, there is the question of the data on which most apology research isbased. As Meier’s review makes clear, though the studies represent a number oftypes of elicitation methods, these predominantly involve some kind of simulateddata, i.e. discourse-completion tests, questionnaires based on specified hypo-thetical encounters, retrospective self-reports, written or oral closed role-play,more open role-play, intuition and informal observation, etc. Clearly, naturallanguage recorded discourse is ‘conceded to be preferable’ (1998: 225) butdifficult to come by (but see Holmes, 1995, 1998; Jaworski, 1994; Obeng, 1999).Like Meier, Holmes (1998: 204) argues that ‘though it is not possible to specify acomplete speech act set for apology, it is both possible and useful for descriptivepurposes to categorize the range of strategies which were used in a corpus ofapologies collected from native speakers of English’. Even more interesting,Jaworski (1994) considers how methods of data collection on apologiesconstrain and influence the results of the various studies. For example, one of the

interfacial tensions for a straight interface. For curved inter-faces, the tensions depend on the curvature and the calcula-tions become more involved. A discussion of some of thekey issues can be found in Ref. 34 and references therein.
When be! 1.2, the gas-liquid interfacial tension clg is0.38kBT/r, corresponding to the case for the profiles dis-played in Fig. 6. The other interfacial tensions are given inTable I, together with the resulting contact angle fromEq. (56). These values are in good agreement with the con-tact angle one can observe from the density profiles in Fig. 6.However, these profiles have a diffuse interface so there isalways some uncertainty in the location of the contact line.As ew is increased the drop spreads because it is energeticallybeneficial to do so. Complete spreading (wetting) occursonly when the sum clg" cwl is less than cwg.
Exercise:
Calculate one of the density profiles from Fig. 6, imple-menting the normalization procedure introduced in Sec. VI Aand then plot the density contour q! (qg" ql)/2, which cor-responds to the mid-point of the liquid–gas interface. Whereon this curve does the contact angle agree with the macro-scopic result in Eq. (56)? Is it where you would expect?
VIII. CONCLUSIONS
We have presented a derivation of a simple lattice gasmodel DFT and discussed typical applications. Workingwith this model gives a good hands-on introduction to manyof the important ideas behind DFT and gives a platform tolearn about different aspects of inhomogeneous fluids suchas phase diagrams, adsorption, wetting, and surface tensions.Studying this “toy-model” gives students good insight and afeeling for the physics of inhomogeneous liquids, leavingthem in a good position to continue on and study the “realthing.”2–6,8–12

13The students involved in these projects have generally been in the finalyear of either a three-year bachelors degree or a four-year masters degree,in either Mathematics & Physics or straight Mathematics. However, twicethese activities were given as summer projects to very good students at anearlier stage in their studies, which worked well too. The final-year proj-ects are typically supposed to be around 200 or 300 h work over the aca-demic year, including meeting with the supervisor for roughly one hourper week. In order to get students started and introduce to them the rele-vant mathematics and physics for these projects, 2–3 h of informal intro-ductory lectures are given; Secs. I–V of this paper are based on theselectures. Some students are also given a computer code written in Maplethat implements the method described in Sec. VI, for the fluid in 1D withjust nearest neighbor interactions, which the student then modifies totackle their particular problem.

Structure Paragraphs
• What is a paragraph? – “A paragraph is a collection of related sentences
dealing with a single topic” (source: OWL) • 1 paragraph: 1 topic
– one idea + several bits of supporting evidence – several points, as long as they relate to the overall
topic of the paragraph » if the single points start to get long, then make new
paragraph
• Structure: topic sentence + supporting details • Ideal length: varies, but never shorter than 3 sentences
Structure Paragraphs
• How do I know when to start a new paragraph? – When you begin a new idea or point – To contrast information or ideas
– When your readers need a pause
(source: OWL)
Structure Paragraphs One factor that has been argued to play a vital role in how conflict is managed by offenders is apology (Darby & Schlenker, 1982; Ohbuchi, Kameda, & Agarie, 1989; Sitkin & Bies, 1993). In the introduction to his landmark book On Apology, psychiatrist Aaron Lazare opens by referring to apology as ‘ ‘One of the most profound human interactions” (Lazare, 2004, p. 1). On a national scale, apologies have helped to heal the wounds of the Holocaust, the Nanking Massacre, and many other atrocities (Brooks, 1999). Within organizational contexts, apologies can be used to resolve interpersonal disputes, improve customer experiences, and enhance leader effectiveness (Liao, 2007; Tomlinson, Dineen, & Lewicki, 2004; Tucker, Turner, Barling, Reid, & Elving, 2006).

Structure Sentence structure
• What is a sentence?
Structure Sentence structure
A sentence may consist of one or more clauses: • Main clause • Main clause + subordinate clause(s)
• Main clause 1 + and/or/but + Main clause 2
Structure Sentence structure
• Typically, a main clause consists of a subject, a verb and an object
– “A topic sentence identifies the main idea of the paragraph.”
• Two main clauses can be connected by “and”, “or”, “but” or a semicolon
– “This compendium consists of commented examples; all of them are taken from your essays.”
SUBJ VERB OBJECT
Structure Sentence structure
• A dependent (or ‘subordinate’) clause can begin with a conjunction (except for “and”, “or” and “but”, which are know as coordinating conjunctions):
“Although not all the results are verified,...” “If that is the case,...” “..., which is a big problem.”
• Or a non-finite verb form: “..., considering the impact of the results.” “..., considered as a whole.” “..., to be considered at a later stage.”
