Numbering same-sex couples in censuses and population registers

The recommendations recently issued by the Conference of European Statisticians (CES) for the next round of population and housing censuses underline for the first time that some countries might find it in their interest to enumerate same-sex couples. Many pitfalls can be expected when such a sensitive topic is newly included in a census. The experience of the few western countries that have already taken initiatives in this direction helps identify difficulties to be faced and suggest "good practices" to be adopted. Coverage is extended to countries which rely on permanent registers rather than periodic censuses to enumerate their population.censuses, population registers, same-sex couples

Spectral interferometric polarised coherent anti-Stokes Raman spectroscopy

We have developed an interferometric implementation of coherent anti-Stokes Raman scattering (CARS) which enables broadband coherent Raman spectroscopy free from non-resonant background (NRB), with a signal strength proportional to concentration. Spectra encode mode symmetry information into the amplitude response which can be directly compared to polarised spontaneous Raman spectra. The method requires only passive polarisation optics and is suitable for a wide range of laser linewidths and pulse durationsComment: 5 pages, 3 figures, submitted to PR

Komunikasi Politik dan Branding Pemimpin Politik Melalui Media Sosial: A Conceptual Paper

The presence of digital media, such as social media allows us to connect without any limitations of space and time. Consumption of social media brings changes in various aspects of life, including the habits of communicating and interacting in today's network society. In the political field, social media creates opportunities for political leaders to carry out political communication. As a strategic political communication channel, social media plays a role in receiving and responding to public aspirations. In fact, the use of social media for campaigns by political leaders shows a trend of increasing popularity and electability due to the influence of branding on social media. The use of social media by political leaders in building specific branding is at the core of this article. Political leaders optimize their personal social media accounts for political communication. The positive perception of the public allows for an increase in popularity and electability which brings to the national political stage. This article is a conceptual paper that analyzes the concept of branding in politics in the era of digital political communication by utilizing social media. The author uses relevant literature reviews from previous studies. This article reveals that several political leaders that have been studied have optimized social media to carry out political communication to their citizens. They display digital content to gain public support and trust, and display branding as a populist, professional, humanist, and responsible political leader

Multimodal optical characterisation of collagen photodegradation by femtosecond infrared laser ablation.

Collagen is a structural component of the human body, as a connective tissue it can become altered as a result of pathophysiological conditions. Although the collagen degradation mechanism is not fully understood, it plays an important role in ageing, disease progression and applications in therapeutic laser treatments. To fully understand the mechanism of collagen alteration, in our study photo-disruptive effects were induced in collagen I matrix by point-irradiation with a femtosecond Ti-sapphire laser under controlled laser ablation settings. This was followed by multi-modal imaging of the irradiated and surrounding areas to analyse the degradation mechanism. Our multi-modal methodology was based on second harmonic generation (SHG), scanning electron microscope (SEM), autofluorescence (AF) average intensities and the average fluorescence lifetime. This allowed us to quantitatively characterise the degraded area into four distinct zones: (1) depolymerised zone in the laser focal spot as indicated by the loss of SHG signal, (2) enhanced crosslinking zone in the inner boundary of the laser induced cavity as represented by the high fluorescence ring, (3) reduced crosslinking zone formed the outer boundary of the cavity as marked by the increased SHG signal and (4) native collagen. These identified distinct zones were in good agreement with the expected photochemical changes shown using Raman spectroscopy. In addition, imaging using polarisation-resolved SHG (p-SHG) revealed both a high degree of fibre re-orientation and a SHG change in tensor ratios around the irradiation spot. Our multi-modal optical imaging approach can provide a new methodology for defining distinct zones that can be used in a clinical setting to determine suitable thresholds for applying safe laser treatments without affecting the surrounding tissues. Furthermore this technique can be extended to address challenges observed in collagen based tissue engineering and used as a minimally invasive diagnostic tool to characterise diseased and non-diseased collagen rich tissues

Avoiding Zoom Fatigue: The Uses and Gratifications on Social Media

The Corona Virus Disease 2019 (Covid-19) pandemic has forced the government to implement Large-Scale Social Restrictions (PSBB) several times. As a result of this policy, it is mandatory to implement the Working From Home (WFH) policy. The company then facilitates its employee with virtual meeting applications, such as Zoom. On the other hand, WFH has a frequent impact and the length of time spent in virtual meetings causes zoom fatigue. The purpose of this study is to determine the uses and gratification of social media users to avoid zoom fatigue when working from home during the Covid-19 pandemic. Social media users use it as a means of fulfilling usability and satisfaction based on the media chosen. This study will describe the uses and gratification of using social media during WFH to avoid “Zoom fatigue†based on Computer-Mediated Communication Theory and Uses and Gratification Theory.The study uses a qualitative approach with an explorative method to find or formulate problems from a phenomenon.  The study uses literature studies based on scientific articles in international and national journals related to the use of social media based on the Uses and Gratification theory in the last ten years. For further exploration, the researcher conducted in-depth semi-structured interviews via email and telephone with three informants. The interview results revealed the uses and gratification for social media users to avoid zoom fatigue while undergoing WFH during the pandemic Covid-19. Social media as a source of entertainment and relaxation, a source of information, spending time, interacting and expressing opinions, and monitoring. The researcher hopes that the results of this study can fill the lack of existing research related to the uses and gratification of social media based on Computer-Mediated Communication and Uses and Gratification Theory. It can also contribute knowledge to practitioners who are content creators, marketing agencies, and online shop owners to optimize content to get high user engagement

ANALYSIS OF SEDIMENTATION TRENDS IN EFFORTS FOR SUSTAINABILITY AT WONOREJO RESERVOIR

Sedimentation is a natural problem that always occurs in water structures, especially dams and reservoirs. Wonorejo Reservoir as a multipurpose reservoir also experienced this. Sedimentation can affect the performance of reservoirs and dams. With the accumulation of sediment, the volume of the reservoir will change from time to time, so it is necessary to estimate the volume of sediment during the useful life of the reservoir and dam, so that they can function optimally. In addition, efforts are also needed to deal with the sedimentation. This study was conducted to estimate the volume of sediment that can occur during the useful life of reservoirs and dams, which is 50 years. Using limited data from previous studies, the study was carried out using the literature study method from other studies that have been carried out in other reservoirs and dams in Indonesia. Based on the estimation results, it is estimated that the volume of sediment in the Wonorejo Reservoir at the end of its age will reach 17.6% of the reservoir capacity volume. So it can be concluded that the reservoir can still work optimally. However, these results are not accurate enough due to the limited data available so that proper sedimentation management efforts are still needed. These countermeasures can be adopted from what has been suggested in other studies for reservoirs and dams in Indonesia
