Educating for digital futures : what the learning strategies of digital media professionals can teach higher education

This article explores how universities might engage more effectively with the imperative to develop students’ 21st century skills for the information society, by examining learning challenges and professional learning strategies of successful digital media professionals. The findings of qualitative interviews with professionals from Australian games, online publishing, apps and software development companies reinforce an increasing body of literature that suggests that legacy university structures and pedagogical approaches are not conducive to learning for professional capability in the digital age. Study participants were ambivalent about the value of higher education to digital careers, in general preferring a range of situated online and face-to-face social learning strategies for professional currency. This article draws upon the learning preferences of the professionals in this study to present a model of 21st century learning, as linked with extant theory relating to informal, self-determined learning and communities of practice.

Learning in formal and informal contexts : conceptions and strategies of Aboriginal and Torres Strait Islander university students

Research suggests that students' approaches to learning and hence learning outcomes are closely related to their conceptions of learning. This paper describes an investigation into conceptions of formal learning held by 22 Aboriginal and Torres Strait Islander students from three Australian universities in Queensland; categories of informal learning, reasons for studying and strategies used to learn were also investigated. The attrition rate for these students in tertiary education is higher than that of any other group of students. The main aim of this study was to determine their conceptions of learning in order to provide information that might facilitate instruction more suited to their needs in order to address the high attrition rate. Results showed that these students view and approach university learning in much the same way as other university students. It was also apparent that, for the most part, the strategies these students used did not match the conceptions of learning they held. An interesting result was the difference between the conceptions of formal learning and perceptions of informal learning.

The Thoughts Questionnaire (TQ) for family caregivers of people with dementia

Objectives: To develop a new measure of dysfunctional thoughts for family caregivers of people living with dementia. These thoughts can contribute to negative outcomes, but they may be modifiable. Method: A stepwise process was used to develop the Thoughts Questionnaire, commencing with item generation, concept mapping, and pilot testing in a sample of professional and nonprofessional caregivers of people with dementia (n = 18). Next, an independent sample of 35 family caregivers of people with dementia (30 female; M age = 64.30, standard deviation = 10.65) completed: (a) the Thoughts Questionnaire; (b) an existing measure of dysfunctional thoughts, the Dementia Thoughts Caregivers Questionnaire; and (c) separate validated measures of depressive symptoms, caregiver stress, and coping, respectively. Results: The level of agreement with dysfunctional thought statements from the Dementia Thoughts Caregivers Questionnaire and Thoughts Questionnaire was low. However, a small number of Thoughts Questionnaire statements were strongly endorsed by over 85% of the sample. Both dysfunctional thought measures had adequate reliability, but total scores were not significantly intercorrelated (r = .287, p = .095). Only the Thoughts Questionnaire was significantly, positively correlated with most caregiver stress measures. Thoughts Questionnaire items required a much lower reading level than the Dementia Thoughts Caregivers Questionnaire items. Discussion: This study provides preliminary data on a tool for assessing the negative role-related thoughts that family caregivers of people with dementia may experience. Given that these thoughts are implicated in depression but they may be modified, the capacity to identify dysfunctional thoughts may prove useful in caregiver support programs.

Educational research and strategies of world-forming: The globe, the unconscious, and the child

The passion to eradicate alterity from the earth is also the passion for the home, the country, the dwelling, that authorizes this desire and rewards it. In its nationalism, parochialism and racism it constitutes a public and private neurosis. So, unwinding the rigid understanding of place that apparently permits me to speak, that guarantees my voice, my power, is not simply to disperse my locality within the wider coordinates of an ultimate planetary context. That would merely absolve me of responsibility in the name of an abstract and generic globalism, permitting my inheritance to continue uninterrupted in the vagaries of a new configuration. There is something altogether more precise and more urgent involved. For in the horror of the unhomely pulses the dread for the dispersal of Western humankind: the dread of a rationality confronted with what exceeds and slips its grasp. (Chambers, 2001, p. 196)

May the best Tweeter win : The Twitter strategies of key campaign accounts in the 2012 US election

The 2008 US election has been heralded as the first presidential election of the social media era, but took place at a time when social media were still in a state of comparative infancy; so much so that the most important platform was not Facebook or Twitter, but the purpose-built campaign site my.barackobama.com, which became the central vehicle for the most successful electoral fundraising campaign in American history. By 2012, the social media landscape had changed: Facebook and, to a somewhat lesser extent, Twitter are now well-established as the leading social media platforms in the United States, and were used extensively by the campaign organisations of both candidates. As third-party spaces controlled by independent commercial entities, however, their use necessarily differs from that of home-grown, party-controlled sites: from the point of view of the platform itself, a @BarackObama or @MittRomney is technically no different from any other account, except for the very high follower count and an exceptional volume of @mentions. In spite of the significant social media experience which Democrat and Republican campaign strategists had already accumulated during the 2008 campaign, therefore, the translation of such experience to the use of Facebook and Twitter in their 2012 incarnations still required a substantial amount of new work, experimentation, and evaluation. This chapter examines the Twitter strategies of the leading accounts operated by both campaign headquarters: the ‘personal’ candidate accounts @BarackObama and @MittRomney as well as @JoeBiden and @PaulRyanVP, and the campaign accounts @Obama2012 and @TeamRomney. Drawing on datasets which capture all tweets from and at these accounts during the final months of the campaign (from early September 2012 to the immediate aftermath of the election night), we reconstruct the campaigns’ approaches to using Twitter for electioneering from the quantitative and qualitative patterns of their activities, and explore the resonance which these accounts have found with the wider Twitter userbase. A particular focus of our investigation in this context will be on the tweeting styles of these accounts: the mixture of original messages, @replies, and retweets, and the level and nature of engagement with everyday Twitter followers. We will examine whether the accounts chose to respond (by @replying) to the messages of support or criticism which were directed at them, whether they retweeted any such messages (and whether there was any preferential retweeting of influential or – alternatively – demonstratively ordinary users), and/or whether they were used mainly to broadcast and disseminate prepared campaign messages. Our analysis will highlight any significant differences between the accounts we examine, trace changes in style over the course of the final campaign months, and correlate such stylistic differences with the respective electoral positioning of the candidates. Further, we examine the use of these accounts during moments of heightened attention (such as the presidential and vice-presidential debates, or in the context of controversies such as that caused by the publication of the Romney “47%” video; additional case studies may emerge over the remainder of the campaign) to explore how they were used to present or defend key talking points, and exploit or avert damage from campaign gaffes. A complementary analysis of the messages directed at the campaign accounts (in the form of @replies or retweets) will also provide further evidence for the extent to which these talking points were picked up and disseminated by the wider Twitter population. Finally, we also explore the use of external materials (links to articles, images, videos, and other content on the campaign sites themselves, in the mainstream media, or on other platforms) by the campaign accounts, and the resonance which these materials had with the wider follower base of these accounts. This provides an indication of the integration of Twitter into the overall campaigning process, by highlighting how the platform was used as a means of encouraging the viral spread of campaign propaganda (such as advertising materials) or of directing user attention towards favourable media coverage. By building on comprehensive, large datasets of Twitter activity (as of early October, our combined datasets comprise some 3.8 million tweets) which we process and analyse using custom-designed social media analytics tools, and by using our initial quantitative analysis to guide further qualitative evaluation of Twitter activity around these campaign accounts, we are able to provide an in-depth picture of the use of Twitter in political campaigning during the 2012 US election which will provide detailed new insights social media use in contemporary elections. This analysis will then also be able to serve as a touchstone for the analysis of social media use in subsequent elections, in the USA as well as in other developed nations where Twitter and other social media platforms are utilised in electioneering.

The SCOTS corpus and TEFL: Discovering and Using Strategies of Spoken English in Finnish Upper Secondary Schools

Suomen koulutuspolitiikasta vastaavat viranomaiset ovat reagoineet kansainvälisten kommunikaatiotarpeiden asettamiin haasteisiin ja muuttaneet yhden lukion A-tasoisen vieraan kielen kurssin sisällön vastaamaan suullisen viestinnän tarpeita. Tutkimuksessa selvitetään, miten englannin puhestrategioita voi opettaa suomalaisille lukiolaisille ja mitä metodeja on käytettävissä puhestrategioiden oppimisen arvioimiseksi. Vastaan asettamiini kysymyksiin aikaisemman tutkimuskirjallisuuden ja englannin kielen lukio-opetuksesta keräämäni aineiston avulla. Keskeisiä elementtejä tutkielmassa ovat erityisesti pragmaattinen kompetenssi ja kolme yleisen tason puhestrategiaa (keskustelun aloittaminen, oman puheenvuoron säilyttäminen sekä keskustelun ylläpitäminen). Aineistossa on mukana 65 ensimmäisen vuosiluokan lukiolaista (luokka A ja B) Helsingistä ja Espoosta. Opetusmateriaalina on käytetty SCOTS korpusta; tarkemmin määriteltynä puhetiedosto nimeltä Conversation 20: Four secondary school girls in the North East. Tiedostossa esille tulleet, kolmeen puhestrategiaan liittyvät fraasit, sanat ja rakenteet havainnollistettiin opiskelijoille mm. AntConc - konkordanssiohjelman avulla. Opiskelijat tekivät myös kirjallisia ja suullisia harjoituksia, jotka liittyivät puhestrategioihin. Neljälle vapaaehtoiselle opiskelijalle suunnattu toinen suullinen tehtävätyyppi vapaamuotoisine keskusteluineen äänitettiin, transkriboitiin ja tuloksia arvioitiin mm. eurooppalaisen viitekehyksen avulla. Lisäksi B - luokka vastasi kyselylomakkeeseen, jossa kysyttiin heidän mielipiteitään esim. hyödyllisimmästä testioppitunnista sekä heidän osallistumishalukkuudestaan uudelle pitkän englannin kahdeksannelle syventävälle kurssille. Tutkimustulokset ovat kannustavia ja osoittavat, että puhestrategioita on mahdollista opettaa jo lukiotasolla. Vaikka tutkimuksessa käytetty lähestymistapa oli opiskelijoille osittain uusi, valtaosa heistä myönsi oppineensa uutta englannin kielen keskustelurakenteista. Lisäksi vapaaehtoisten opiskelijoiden äänitetyt ja transkriboidut keskustelut tarjoavat hyvän lähtökohdan mahdolliselle jatkotutkimukselle.

Aspects of reproduction and diet of the Australian endemic skate Dipturus polyommata (Ogilby) (Elasmobranchii: Rajidae), by-catch of a commercial prawn trawl fishery

The Australian endemic skate Dipturus polyommata collected from by-catch of a benthic prawn fishery off southern Queensland was examined to provide information on reproduction and diet. Morphological relationships of total length (LT) to disc width and LT to mass were estimated. Size at birth was estimated at c. 100-110 mm and size at first feeding at c. 105-110 mm LT. Size at 50% maturity (LT50 and 95% CI) was 321 (305-332) and 300 (285-306) mm LT for females and males, respectively. Size at first maturity corresponded to 87.7% of observed maximum size in females (366 mm LT) and 87.5% in males (343 mm L T). Two females, representing 18.2% of mature females sampled in the austral winter were each carrying two egg cases. Descriptions of egg cases are given. Diet described by the index of relative importance as a percentage (%IRI) was predominantly crustacean based with carid shrimps (53.64%) and penaeoid prawns (23.30%) the most significant prey groups. Teleosts (11.72%), gammarid amphipods (5.31%) and mysids (4.72%) were also important to the diet of the species, while a further six prey groups made only a minor contribution to diet (1.31%). An ontogenetic change was evident between the diets of immature and mature skates. Immature animals fed more extensively on carids and amphipods and mature animals on penaeoids, teleosts and mysids.

Preliminary investigation into the induction of reproduction in Ulva spp. in Southeast Queensland for mass cultivation purposes

Ulva is a common component of marine intertidal flora in Australia with many species frequently observed along the Queensland coastline. Three species of Ulva, U. lactuca, U. intestinalis and U. prolifera were found to naturally occur at the Bribie Island Research Centre (BIRC) in Southeast Queensland. Studies were undertaken to establish the most optimal conditions for growing Ulva in the BIRC laboratory. These tests were conducted in order to condition the algal material prior to the sporulation studies, offering more controlled material to assess treatment effects conclusively, and helping eliminate other potentially confounding environmental factors. Results showed that a stocking density of between 5-20 grams of Ulva per litre along with the addition of the soluble fertiliser Aquasol at a rate of 87 mg/L of seawater was ideal for achieving a desired doubling of growth per week. In the wild the formation of Ulva fragments occurs naturally in the ocean through wave and storm action. This breakage can trigger a survival response mechanism which stimulates the algae to form and release gametes. By chopping the tissue, this process could be artificially simulated in the laboratory and creating a simple and easy way to produce new individuals. Studies performed into inducing sporulation in Ulva through a combination of fragmentation and renewal of medium at BIRC showed that sporulation can be successfully induced in all three species of Ulva through these methods, however it was found to be to a degree that would not meet the demands of commercial production with on average a rate of only 33% achieved. While the current study did not find a method suitable for a commercial application the results presented here contribute to increasing our understanding about Ulva reproduction and set a platform for future work in to cultivating Ulva within Southeast Queensland.

Rearing strategies of young dairy calves in relation to production, behaviour and welfare

Vasikoiden kasvatus yksilökarsinoissa, imemismahdollisuuden puute maitojuoton yhteydessä sekä pienet juomamäärät ovat tekijöitä, jotka mahdollisesti voivat vähentää vasikoiden hyvinvointia. Vasikoiden kasvatukseen etsitäänkin uusia tapoja, joissa eläinten käyttäytymistarpeet ja hyvinvointi otetaan entistä paremmin huomioon. Tässä väitöskirjassa vasikoiden kasvatusta on tarkasteltu sekä tuotannon että vasikoiden käyttäytymisen ja hyvinvoinnin kannalta. Väitöskirja koostuu kolmesta kokeesta, joista ensimmäisessä tutkittiin vasikoiden kasvatusta ryhmäkarsinoissa ulkona tai sisällä ja vasikoiden kasvatusta sisällä ryhmä- tai yksilökarsinoissa. Toisessa kokeessa vasikoiden annettiin imeä emiään rajoitetusti lypsyn jälkeen viiden tai kahdeksan viikon ajan ja kolmannessa selvitettiin vasikoiden veden juontia, kun vasikat saivat juomarehua vapaasti. Lisäksi kokeiden yhdistetystä aineistosta analysoitiin eri rehujen syöntimäärien suhdetta sekä rehujen vaikutusta kasvuun ennen ja jälkeen maidosta vieroituksen. Tutkimuksessa todettiin, että vasikoita voi ryhmässä kasvattaa kylmissä ja vaihtelevissa sääoloissa ulkona, kunhan ne hoidetaan ja ruokitaan erittäin huolellisesti. Kylmällä ilmalla vasikat saattavat kuitenkin syödä väkirehua vähemmän varsinkin, jos ruokailupaikka on ulkona ja makuualue sisällä. Ryhmässä kasvaneet vasikat aloittivat sekä kuivien rehujen syönnin että märehtimisen nuorempina kuin yksilökarsinassa kasvaneet. Ryhmissä esiintyvää käyttäytymisongelmaa, toisten vasikoiden imemistä, voidaan vähentää hoito- ja ruokintamenetelmillä. Annettaessa vasikoiden imeä emiään rajoitetusti lypsyn jälkeen vasikat oppivat imemään emiään hyvin nopeasti. Lypsytyö vaikeutui muutamien lehmien kohdalla, sillä ne pidättivät maitoa lypsettäessä. Saadessaan imeä rajoitetusti vasikat imivät suurehkoja maitomääriä kerrallaan. Vieroittaminen suurilta maitomääriltä viiden viikon iässä oli kuitenkin liian aikaista, koska vasikat eivät vielä syöneet riittävästi kuivia rehuja. Vieroitus emästä niin viiden kuin kahdeksankin viikon iässä aiheutti vasikoissa levottomuutta ja ääntelyn lisääntymistä. Saadessaan hapatettua juomarehua vapaasti vasikat joivat keskimäärin vain vähän vettä, olipa vesilähteenä avoin ämpäri tai vesinippa. Vasikoiden välillä oli suurta vaihtelua veden juontimäärissä. Viikkoa ennen maidosta vieroitusta vasikat joivat 0-3 l vettä päivässä. Vasikat joivat nipasta kerrallaan vähemmän vettä kuin ämpäristä, ja käyttivät enemmän aikaa päivässä veden juomiseen kuin vesiämpäristä juoneet vasikat. Suurin osa vasikoista joi vettä juomanipoista erikoisella tavalla esimerkiksi painamalla nippaa otsalla ja juomalla tippuvaa vettä. Vesinipat voivat olla siis vasikoille joko vaikeita tai epämukavia käyttää. Vasikoiden juoman maitomäärän lisääntyessä kasvu lisääntyy selvästi. Runsas maidon juominen vähentää kuitenkin kuivien rehujen syöntiä ja vieroitusvaiheessa kasvu voi hidastua. Vasikat olisikin tärkeää vieroittaa vähitellen, ettei muutoksia kasvuun tulisi. Syönti- ja kasvutulokset eivät aina anna oikeaa kuvaa kasvatusmenetelmien eroista eläinten hyvinvoinnin kannalta. Käyttäytyminen on herkkä hyvinvoinnin mittari ja se tulisikin aina huomioida eri kasvatusmenetelmiä arvioitaessa. .

Strategies of synthesis of aromatic polyketides using cyclohexa-1,4-and-1,3-dienes in Alder Rickett reactions

Cyclohexa-1, 4-dienes with appropriate substituents, obtained by birch reduction of the substituted benzene, react directly with derivatives of propiolic ester or aldchyde to yield aromatic polyketides. The following compounds have been synthesized; mycophenolic acid, nidulol methyl other, the root growth hormone 3, 5-dihydroxy-2-formyl-4-mythyl-benzoic acid, antibiotic DB 2073, the macrocyclic lactones lasiodiplodin and dihydrozearalenone and the biphenyl derivatives alternario and altenusin. Polyketide anthraquinones can be made from naphthoquinone precursors.

Strategies of synthesis based on dihydrobenzenes

1-Methoxycyclohexa-1,4-dienes are readily available from the metal-ammonia-alcohol reduction of aromatic ethers. The use of these dihydrocompounds in the synthesis of a variety of natural products is reviewed.
