Mining Emotions from the Finnish War Letter Collection, 1939–1944

Our paper analyses emotional language used by Finnish soldiers and civilians in their private communication during World War II. The dataset consists of 7,000 handwritten letters converted into a machine-readable corpus with rich metadata. The dataset offers a unique opportunity to make a statistical analysis of people’s emotional responses to the war. We engage in key questions of the cultural history of war, such as the connection between soldiers’ emotional language and violence: did soldiers’ emotional language become more laconic in the course of the war? While computational approaches to mining emotions have been common in fields like computer science and linguistics, they have not gained wider popularity in historical research. Pioneering attempts have been based on individual emotion words carefully chosen by an historian, or on readily available, more generic emotion lexicons. Compared to machine-learning solutions, lexicon-based approaches require less computational effort and are more transparent to interpret. Our methodology combines the ready-made word list FEIL with contextual knowledge of historians. FEIL gives around 7,000 Finnish words an emotion category and intensity ratings. First, the emotion lexicon was filtered based on high intensity. Then the domain expert manually removed words not particularly emotionally intensive in the context of war letters. The expert also annotated the list of the most frequent words in the war letter collection and handpicked emotionally intensive words not included in FEIL. Our final list covered 298 emotion words. We quantified changes in their use over time. In contrast to earlier research, our analysis indicates that soldiers’ and civilians’ emotionality did not significantly differ during World War II. Soldiers’ use of emotion words saw a decline in the last stages of the war, but overall their letters were almost as emotional as the civilians’ letters. We did indeed identify some changes in the individual emotion words used by the soldiers in their letters: patriotic words in particular decreased in the course of the war. In addition to empirical findings, our paper sheds light on the problem of universal emotion lexicons in historical research: linguistic, cultural and temporal differences between present-day lexicons and historical datasets can lead to biased interpretations. Thus, our paper contributes not only to the history of emotions but also to emotion mining, which is historically sensitive.publishedVersionPeer reviewe

Comparison of Terrestrial Laser Scanning and X-ray Scanning in Measuring Scots Pine (Pinus sylvestris L.) Branch Structure

While X-ray scanning is increasingly used to measure the interior quality of logs, terrestrial laser scanning (TLS) could be used to collect information on external tree characteristics. As branches are one key indicator of wood quality, we compared TLS and X-ray scanning data in deriving whorl locations and each whorl's maximum branch and knot diameters for 162 Scots pine (Pinus sylvestris L.) log sections. The mean number of identified whorls per tree was 37.25 and 22.93 using X-ray and TLS data, respectively. The lowest TLS-derived whorl in each sample tree was an average 5.56 m higher than that of the X-ray data. Whorl-to-whorl mean distances and the means of the maximum branch and knot diameters in a whorl measured for each sample tree using TLS and X-ray data had mean differences of -0.12 m and -6.5 mm, respectively. One of the most utilized wood quality indicators, tree-specific maximum knot diameter measured by X-ray, had no statistically significant difference to the tree-specific maximum branch diameter measured from the TLS point cloud. It appears challenging to directly derive comparative branch structure information using TLS and X-ray. However, some features that are extractable from TLS point clouds are potential wood quality indicators.Peer reviewe

From Sustainability-as-usual to Sustainability Excellence in Local Bioenergy Business

Bioenergy business operators can significantly contribute to the sustainability of bioenergy systems. While research has addressed the maturity of corporate responsibility for sustainability, the maturity levels of bioenergy business have not been determined. The objectives of this research were to characterise the maturity levels of bioenergy corporate responsibility for sustainability and outline an approach by which companies can operate at the most mature sustainability excellence level. Literature, three workshops attended by bioenergy experts and a case study on biobutanol production in Brazil were used to develop the maturity model and approach. The results characterise the profitability, acceptability, and sustainability orientation maturity levels through sustainability questions and methods, and list the components of a systemic, holistic approach. Although the shift of business mindset from sustainability-as-usual to sustainability excellence is challenging, a systemic approach is necessary to broadly identify sustainability questions and a multitude of methods by which they can be answered

A comprehensive model for measuring real-life cost-effectiveness in eyecare : automation in care and evaluation of system (aces-rwm (TM))

This paper describes a holistic, yet simple and comprehensible, ecosystem model to deal with multiple and complex challenges in eyecare. It aims at producing the best possible wellbeing and eyesight with the available resources. When targeting to improve the real-world cost-effectiveness, what gets done in everyday practice needs be measured routinely, efficiently and unselectively. Collection of all real-world data of all patients will enable evaluation and comparison of eyecare systems and departments between themselves nationally and internationally. The concept advocates a strategy to optimize real-life effectiveness, sustainability and outcomes of the service delivery in ophthalmology. The model consists of three components: (1) resource-governing principles (i.e., to deal with increasing demand and limited resources), (2) real-world monitoring (i.e., to collect structured real-world data utilizing automation and visualization of clinical parameters, health-related quality of life and costs), and (3) digital innovation strategy (i.e., to evaluate and benchmark real-world outcomes and cost-effectiveness). The core value and strength of the model lies in the consensus and collaboration of all Finnish university eye clinics to collect and evaluate the uniformly structured real-world outcomes data. In addition to ophthalmology, the approach is adaptable to any medical discipline to efficiently generate real-world insights and resilience in health systems.Peer reviewe

High-Power 1180-nm GaInNAs DBR Laser Diodes

We report high-power 1180-nm GaInNAs distributed Bragg reflector laser diodes with and without a tapered amplifying section. The untapered and tapered components reached room temperature output powers of 655 mW and 4.04 W, respectively. The diodes exhibited narrow linewidth emission with side-mode suppression ratios in the range of 50 dB for a broad range of operating current, extending up to 2 A for the untapered component and 10 A for the tapered component. The high output power is rendered possible by the use of a high quality GaInNAs-based quantum well gain region, which allows for lower strain and better carrier confinement compared with traditional GaInAs quantum wells. The development opens new opportunities for the power scaling of frequency-doubled lasers with emission at yellow–orange wavelengths.publishedVersionPeer reviewe

A 6-Month Study Comparing Efficacy, Safety, and Tolerability of the Preservative-free Fixed Combination of Tafluprost 0.0015% and Timolol 0.5% versus Each of Its Individual Preservative-Free Components

The efficacy, safety and tolerability of the preservative-free (PF) fixed combination (FC) of tafluprost 0.0015\% and timolol 0.5\% (once daily) were compared to those of the individual components (PF tafluprost 0.0015\% once daily and PF timolol 0.5\% twice daily) in patients with open-angle glaucoma or ocular hypertension inadequately controlled on prior timolol or prostaglandin monotherapy for 6\ua0months.A stratified, double-masked, randomized, multicenter phase III study was conducted. A total of 189 prior timolol users were randomized within the timolol stratum (TS) to receive either FC (n\ua0=\ua095) or timolol 0.5\% (TIM; n\ua0=\ua094). Furthermore, a total of 375 prior prostaglandin analog (PGA) users were randomized within the prostaglandin stratum (PS) to receive either FC (n\ua0=\ua0188) or tafluprost 0.0015\% (TAF; n\ua0=\ua0187). To be eligible for participation in the study, the patients were required to have an intraocular pressure (IOP) of\ua0 6522\ua0mmHg when on timolol (TIM) or of\ua0 6520\ua0mmHg when on PGA in either treated eye at the screening and end-of-run-in visits. In addition to these, the study included visits at baseline, 2 and 6\ua0weeks, 3 and 6\ua0months and at a post-study visit. IOP was measured at 8 a.m., 10 a.m., 4 p.m., and 8 p.m.In the TS, a significant reduction from baseline IOP was seen with FC and TIM throughout the study. Average diurnal IOP change from baseline at month 3 was -8.55\ua0mmHg (32\%) for FC and -7.35\ua0mmHg (28\%) for TIM. The model-based treatment difference (FC-TIM) was -0.885\ua0mmHg [95\% confidence interval (CI) -1.745 to -0.024; p\ua0=\ua00.044] demonstrating the superiority of FC over TIM. In the PS, a significant reduction in IOP was seen with both FC and TAF throughout the study. The average diurnal IOP change from baseline at month 3 was -8.61\ua0mmHg (33\%) for FC and -7.23\ua0mmHg (28\%) for TAF. The model-based treatment difference (FC-TAF) was -1.516\ua0mmHg (95\% CI -2.044 to -0.988; p\ua0<\ua00.001) demonstrating the superiority of FC over TAF. In the TS, related ocular adverse events (AEs) were more frequent for patients treated with FC compared to TIM (16.8\% versus 6.4\%), whereas related non-ocular AEs were more frequent with TIM compared to FC (2.1\% versus 0.0\%). In the PS, AEs were similarly distributed between FC and TAF. The frequency of conjunctival hyperemia of FC was low (6.4\%).The preservative-free fixed combination of tafluprost and timolol provided a substantial and significant IOP reduction in both strata. The IOP reduction was superior to both tafluprost 0.0015\% and timolol 0.5\% when given as monotherapies. Overall, the study treatments were safe and well tolerated.Santen Oy, Tampere, Finland
