Repurposing Digital Methods in a Post-API Research Environment: Methodological and Ethical Implications
No full textEspecially after the social media curtailing brought about the Cambridge Analytica scandal, it has become increasingly difficult to do social media research by using digital methods as well as following the medium. This condition brings in new methodological and ethical challenges. This article proposes some methodological strategies to ‘repurpose’ digital methods in a post-API research environment. The discussion draws on three case studies: 1) studying Instagram stories: the scraping dilemma; 2) studying smartphone in everyday contexts: researching digital environments not connected to APIs; 3) studying fake news on Twitter: dealing with increasingly useless APIs data. For each case study methodological and ethical implications are examined. In conclusion, the article suggests that a possible viable strategy to repurpose digital methods in a post-API era is to follow the natives (along with the medium), that is, to take advantage of the natively digital methods through which social media users manage their own data as well as emic conception of what is ethical (or at least acceptable) regarding the handling of their own data

No full textStudying Instagram Beyond Selfies
No full textOf approximately 40 billion photos posted on Instagram, only 282 million are selfies—just 0.7%. Thus, for all its zeitgeisty appeal, the selfie is in fact a niche phenomenon in the larger context of Instagram genres. Noting this fact, we identified an opportunity to engage with scholars from all over the world with the challenge of proposing new theories and approaches capable of unlocking the full socio-anthropological potential of Instagram. As the articles collected in this special issue testify, Instagram has an enormous impact on people’s everyday lives on many levels—socially, culturally, economically, and politically—and so, indubitably, it deserves rigorous academic attention. Given the scale and complexity of these impacts, studying Instagram poses different kinds of challenges and many gaps are still to be filled. With this special issue we don’t claim to resolve all the issues noted above. More modestly, our goal is to kick-start a fruitful conversation among social media scholars interested in furthering Instagram studies
Irrigation of intensive olive groves in the Mediterranean environment with different water regimes on two different soils: effects on yields, water use efficiency, vegetative behaviour and water status of the crop
No full textTo cope with the FAO motto 'more food with less water' it will be important to define the irrigation strategy not only according to the variety and type of olive grove but also based on the available soil. A certain number of papers focused on assessing the effects of different water regimes on different cultivars and/or agronomical characteristics of the grove while is very difficult to find studies that try to evaluate those effects of different soils. With the aim to give a contribution in elucidate the role of the soil characteristics on water management, two experimental trials have been carried on during the same two years in olive groves with same cultivar, very similar agronomical characteristics, and climatic conditions but with quite different soils, one shallow and silty and the other deep and silty-loamy. Compared water regimes were a dry control (T0) and two irrigated with restitution of 50% (T50(WR)) and 100% (T100(WR)) of the watering volume required to restore the full crop evapotranspiration. Main results are: (i) shoot growth did not differ among water regimes; (ii) leaf water potential decreased from the T100(WR) to the T0; (iii); T50(WR) and T100(WR) showed a very significant increase of yields, particularly different in terms of drupes (much higher in the deep soil) but much more similar in terms of oil between the two soils; (iv) oil content increase in TWR respect to T0, although somewhat less on the deep soil (22.81% in average for TWR treatments and 17.32% for T0, based on two years); (v) seasonal irrigation volumes were widely different between years (72 and 800% higher in the dry year respect to the rainy year for the shallow and the deep soil, respectively) but not so different between soils in the very dry year (23% higher in the deep soil)
Framing #Brexit on Twitter: The EU 27’s lesson in message discipline?
Full text linkThis study examines the ways in which and reasons why the remaining Member States of the European Union, the EU 27, communicated about Brexit on the most popular social media in politics – Twitter, by drawing on a multi method examination of UK-based EU 27 diplomatic entities’ Twitter practices during the process of Brexit negotiations. The findings suggest that the EU 27 maintained message consistency on the topic of Brexit on Twitter, supporting the EU’s negotiating position, demonstrating internal cohesiveness and potentially contributing to the EU’s effectiveness in the Brexit negotiations. Our study also reveals that the framing of Brexit on Twitter was deliberate and strategic, but with a range of different motivations behind the promotion of certain frames. Finally, Twitter is seen by diplomats as a tool conducive to meeting public diplomacy’s aim of relationship-building, but not one to be used for advocacy and influencing interpretation of controversial Brexit issues
