Authors: Klamert Lisa , Craike Melinda , Bedi Gillinder , Kidd Susan , Pascoe Michaela C. , Parker Alexandra G. 
Published: September 2023

AbstractAimThis systematic review investigates behaviour change techniques in interventions promoting physical activity for young people aged 12–25 years at heightened risk of problematic substance use, and the effect of these techniques on physical activity participation and substance use outcomes.MethodsFour databases (PsycINFO, CINAHL, SPORTDiscus and Medline) were searched between November 2020 and November 2022 for randomized and non‐randomized controlled studies according to inclusion criteria. Meta‐analyses were calculated using weighted, standardized averages of effect sizes (Hedges' g).ResultsTwenty‐eight studies were included, 14 studies in the meta‐analysis (intervention n = 1328; control n = 845). Reported BCTs included behavioural instructions, social comparison and goal setting. There was a significant effect of behaviour change techniques on combined substance use outcomes, such as cravings and consumption, for interventions reporting multiple behaviour change techniques (g = −0.33, p < .001, 95% CI [−0.50,−0.16]) or one single behaviour change technique (g = −1.84, p < .001, 95% CI [−2.89,−0.8]). Limitations include unexplained variance and limited reporting of relevant behaviour change technique data in the included studies.ConclusionThe results indicate that using behaviour change techniques in interventions that promote physical activity for young people has an effect on substance use. Further research needs to be completed comparing the impact of the number and type of behaviour change technique, and improved reporting of intervention content is required.
“Doubting with”: An opportunity to renew the debate on researcher–practitioner collaboration
Authors: Arnoud Justine , Peton Hélène 
Published: September 2023

AbstractThis article explores “doubting with” in collaborative management research. Extending methodological reflections on collaboration between researchers and practitioners, this article, drawing on the foundations of the pragmatist inquiry, stresses the central role of doubt and the doubtful situation in overcoming difficulties that are encountered in problem‐oriented approaches. We propose guidelines for “doubting with” in collaborative research, highlighting how it transforms modes of researcher–practitioner collaboration and the opportunities it provides to restore possibilities of action with a broader social dimension. We emphasize how “doubting with” addresses the challenges of collaboration and the key implications for management research regarding the importance of keeping doubt alive in our inquiries and of doubting with practitioners.
Prediction of US 30‐years‐treasury‐bonds movement and trading entry point using the robust 1DCNN‐BiLSTM‐XGBoost algorithm

AbstractThis article presents a novel algorithm that accurately predicts market trends and identifies trading entry points for US 30‐year Treasury bonds. The proposed method employs a hybrid approach, integrating a 1‐dimensional convolutional neural network (1DCNN), long‐short term memory (LSTM), and XGBoost algorithms. The 1DCNN is used to learn local and short‐term patterns, while LSTM is employed to capture both short and long‐term dependencies. Furthermore, we have implemented an algorithm that utilizes hull moving average (HMA) and simple moving average (SMA) crossover data to detect trading entry points and major trends in the market. The combination of the SMA–HMA crossover algorithm and predictions provided by the 1DCNN‐BiLSTM‐XGBoost algorithm yields exceptional results in terms of prediction accuracy and profitability. Additionally, these integrated techniques effectively filter out noise and mitigate false breakouts, which are often observed with US 30‐year Treasury bonds. In the field of financial time series prediction, the effectiveness of 1DCNN and LSTM in identifying trading entry points and market perturbations has not been comprehensively studied. Therefore, our work fills this gap by demonstrating through experiments that the proposed 1DCNN‐BiLSTM‐XGBoost algorithm, in combination with moving average crossovers, effectively reduces noise and market perturbations. This leads to the precise identification of trading entry points and accurate recognition of trend signals for US 30‐year Treasury bonds. We demonstrate through experiments that our proposed approach achieves an average root mean squared error of 0.0001 and an R‐square value of 0.9999, highlighting its promise as a method for predicting market trends and trading entry points for US 30‐year Treasury bonds.
Integrating hydrological connectivity and zooplankton composition in Arctic ponds and lakes

Abstract

Arctic landscapes are characterised by their numerous ponds and lakes. With increased climate warming and consequent changes in hydrological connectivity, the ecology of many of these waterbodies is expected to change.

We sampled 13 ponds and 22 lakes for zooplankton and various limnological and physical environmental variables in the vicinity of Cambridge Bay, Nunavut (69.1169° N, 105.0597° W), with the aim of testing how well the degree of hydrological connectivity explained patterns in species composition and abundance and contributed to crustacean production. Ponds were hydrologically isolated while the lakes were arranged in four lake chains and ranged from the headwaters to highly inter‐connected lakes receiving water from one to 768 upstream lakes.

In all sites combined, 77 zooplankton species were found, including 56 rotifers, six copepods, 11 cladocerans, two fairy shrimp species, a mysid, and a tadpole shrimp. We show that the zooplankton communities differed between hydrologically isolated (ponds) and connected (lakes) systems, with 17 species unique to ponds and 20 to lakes. Furthermore, the communities were more similar within lake chains and hence in lakes closer to each other. In ponds, distances between waterbodies had no impact on community similarity.

Zooplankton abundance was higher in lakes (255 ind/L) than in ponds (65 ind/L) due to the higher number of rotifers that accounted for nearly 80% of the zooplankton abundance in lakes. In ponds, rotifers, cladocerans, and copepods were equally abundant. In terms of biomass, cladocerans represented 65% of total biomass in all waterbodies except for a chain of deep lakes that had abundant fish communities. In these lakes, cladoceran abundance and biomass were low and probably limited by fish predation.

Zooplankton production was higher in ponds (4.6 mgC m−3 day−1) than in lakes (1.7 mgC m−3 day−1), and within lakes was lowest in the chain composed of large lakes (1.3 mgC m−3 day−1). The high production in ponds was closely linked to high zooplankton biomass and further explained by high gross primary production supported by relatively high nutrient concentrations in these shallow systems.

Our study emphasises that hydrological connectivity is key to shaping zooplankton communities, although fish presence also appears to affect them. It shows that isolated ponds (that currently account for c83% of all waterbodies on southern Victoria Island) are hotspots of aquatic biological productivity that probably play an essential role in Arctic freshwater landscapes. Finally, our study provides critical baseline information on the current composition of Arctic zooplankton communities important for estimating climate change impacts.

Published: September 2023

AbstractThe impact of Zr addition on the solid sintering process of SiBCN multiphase ceramics was investigated under high temperatures. To gain deep insight, SiBCN‐Zr diffusion couple method (sample preparation at 1500–1800°C) was utilized in conjunction with first‐principles calculations. Significantly, the results demonstrated the formation of SiC and BN as well as ZrC/ZrB2 at the interface of the diffusion couples. Possible mechanisms have been analyzed and proposed. On the one hand, the extensive generations of defects are supposed to facilitate the formation of SiC and ZrC during the preparation of SiBCN amorphous powders. On the other hand, the presence of distinctive BN(C) structures in SiBCN hindered the formation of ZrB2, thus causing a delay in its formation. Through first‐principles calculations, remarkable variations in interatomic bonding strengths have been revealed among the different phases at the interface. Specifically, interfaces of ZrC/ZrB2 and SiC exhibit stronger bonding strengths compared to BN and SiC, implying that Zr, and its compounds may act as binding agents.
Integrating Systemic Risk into Modern Portfolio Theory and Practice
Authors: Lydenberg Steve 
Published: September 2023

Conventional wisdom holds that the performance of investment managers should be measured against some broad market index such as the S&P 500. The broad market averages provide a useful benchmark because they are assumed to be beyond the influence of investment managers and provide a way of capturing what financial economists call “systematic risk,” which is the part of total risk that cannot be avoided through portfolio diversification. But one clear limitation of such an approach to performance evaluation is that by focusing on risks and rewards at the portfolio level only, it fails to consider risks and rewards at a systemic level, where the performance of all portfolios is increasingly likely to be affected.The author begins by making the case that the performance evaluation and collective decision‐making of investment managers could have the effect of increasing the level of systematic risk in both the markets and the real economy. Then, after suggesting that the strength or weakness of environmental, social, and governance (ESG) frameworks can have substantial effects on overall market returns, he discusses a number of efforts currently underway to integrate ESG factors into portfolio‐level decision‐making.The author closes by urging asset owners to take the following three steps to help bridge the gap between investment decision‐making and ESG consequences: (1) acknowledge the connection between investment decision‐making and systems‐level risks and rewards; (2) determine which systemic frameworks are most appropriate and useful for their purposes; and (3) implement investment practices that allow them to manage systemic‐level risks and rewards while simultaneously achieving competitive financial returns in their portfolios. With the help of new measurement and management tools, asset owners can strengthen systemic frameworks, communicate the importance of ESG performance to their investees and investors, and align their efforts with those of governmental and non‐governmental organizations to limit systemic risk.
Do Corporate Managers Know When Their Shares Are Undervalued? New Evidence Based on Actual (and Not Just Announced) Stock Buybacks
Authors: Dittmar Amy , Field Laura Casares 
Published: September 2023

This article summarizes the findings of the authors' recent study, published in the Journal of Financial Economics, of whether public companies are able to repurchase their own shares at a discount to the market, thereby earning more than a market return on such “investments.” To the extent the answer is yes, it would suggest that management has an advantage in assessing the intrinsic value of the companies they manage.Using as their sample all 2,237 publicly traded U.S. companies that repurchased their own stock between 2004 and 2011, the authors compared the average price paid during the month to the average price at which the firm's shares traded during that month as well as three and six months after the repurchase. (All earlier studies had measured stock performance from the date of the repurchase announcements rather than from the date of the actual repurchases.) The authors' conclusion, which may come as more of a surprise to financial economists than practicing corporate executives, was that the majority of companies repurchasing their shares have in fact earned a positive return on their investment in their own stock.Perhaps the most important finding of the study, however, was that infrequent repurchasers—defined as companies that bought back their own stock four or fewer times a year—have been much more successful in buying undervalued shares than regular repurchasers. For example, when evaluated over a six‐month holding period, the annual “alpha” of infrequent repurchasers was 2.4% greater than that of frequent repurchasers—those that bought back their shares at least nine times a year. And this advantage was even more significant for companies that repurchased just once during the year—a group that recorded an alpha of 5.9%, as compared to 1.5% for monthly repurchasers.Moreover, the results were essentially the same when extended over considerably longer holding periods. For the entire sample of companies that repurchased their shares, the authors reported finding positive and significant alphas of 0.3% per month over windows ranging from three months to three years after the repurchase. But, as reported above, the infrequent repurchasers significantly outperformed frequent repurchasers over all time horizons, with differences in alpha that ranged from a low of 0.3% and to as high as 0.6% per month.
First record of Pseudoterranova decipiens in sprat (Sprattus sprattus) from the Baltic Sea
Authors: Nadolna‐Ałtyn Katarzyna , Pawlak Joanna , Pachur Marzenna 
Published: September 2023

AbstractA dispersion of Anisakidae nematodes (particularly Contracaecum osculatum) among marine organisms in the Baltic Sea has been reported over the last decade. This is in line with an increase in the number of grey seal that act as final host for Contracaecum osculatum and Pseudoterranova sp., and are thus indispensable for the completion of their life cycles. Most attention has been paid to zoonotic nematode species, like Pseudoterranova sp., which have been noted in commercially important fish in the area. Little is known about the spread and transmission of Pseudoterranova sp. in the Baltic Sea. The aim of this study was to investigate whether sprat may play a role as a transport host for this Anisakidae. Samples were collected in three areas of the southern Baltic Sea (south and east of Bornholm, Słupsk Farrow and the Gulf of Gdańsk) during a research cruise in August 2019. A visual inspection of the viscera of 556 sprats was conducted. Parasites were identified using anatomomorphological and molecular methods. Nematodes were recorded only in sprat caught southeast of Bornholm (prevalence 2.7%; intensity of infection 1–4; abundance 0.05). Molecular identification revealed the presence of Pseudoterranova decipiens. This is the first report of P. decipiens in sprat from the Baltic Sea. Sprat is likely a transmitter of P. decipiens in the Baltic Sea food web.

AbstractBackground and AimsNeuronal intranuclear inclusion disease (NIID) is a rare progressive neurodegenerative disorder mainly caused by abnormally expanded GGC repeats within the NOTCH2NLC gene. Most patients with NIID show polyneuropathy. Here, we aim to investigate diagnostic electrophysiological markers of NIID.MethodsIn this retrospective dual‐center study, we reviewed 96 patients with NOTCH2NLC‐related NIID, 94 patients with genetically confirmed Charcot–Marie‐Tooth (CMT) disease, and 62 control participants without history of peripheral neuropathy, who underwent nerve conduction studies between 2018 and 2022.ResultsPeripheral nerve symptoms were presented by 53.1% of patients with NIID, whereas 97.9% of them showed peripheral neuropathy according to electrophysiological examinations. Patients with NIID were characterized by slight demyelinating sensorimotor polyneuropathy; some patients also showed mild axonal lesions. Motor nerve conduction velocity (MCV) of the median nerve usually exceeded 35 m/s, and were found to be negatively correlated with the GGC repeat sizes. Regarding the electrophysiological differences between muscle weakness type (n = 27) and non‐muscle weakness type (n = 69) of NIID, nerve conduction abnormalities were more severe in the muscle weakness type involving both demyelination and axonal impairment. Notably, specific DWI subcortical lace sign was presented in only 33.3% of muscle weakness type, thus it was difficult to differentiate them from CMT. Combining age of onset, distal motor latency, and compound muscle action potential of the median nerve showed the optimal diagnostic performance to distinguish NIID from major CMT (AUC = 0.989, sensitivity = 92.6%, specificity = 97.4%).InterpretationPeripheral polyneuropathy is common in NIID. Our study suggest that nerve conduction study is useful to discriminate NIID.
Identification of novel proteins regulating lipid droplet biogenesis in filamentous fungi

Published: September 2023

AbstractLipid droplets (LDs) are storage organelles for neutral lipids which are critical for lipid homeostasis. Current knowledge of fungal LD biogenesis is largely limited to budding yeast, while LD regulation in multinucleated filamentous fungi which exhibit considerable metabolic activity remains unexplored. In this study, 19 LD‐associated proteins were identified in the multinucleated species Aspergillus oryzae using a colocalization screening of a previously established enhanced green fluorescent protein (EGFP) fusion library. Functional screening identified 12 lipid droplet‐regulating (LDR) proteins whose loss of function resulted in irregular LD biogenesis, particularly in terms of LD number and size. Bioinformatics analysis, targeted mutagenesis, and microscopy revealed four LDR proteins that localize to LD via the putative amphipathic helices (AHs). Further analysis revealed that LdrA with an Opi1 domain is essential for cytoplasmic and nuclear LD biogenesis involving a novel AH. Phylogenetic analysis demonstrated that the patterns of gene evolution were predominantly based on gene duplication. Our study identified a set of novel proteins involved in the regulation of LD biogenesis, providing unique molecular and evolutionary insights into fungal lipid storage.

Published: September 2023

AbstractBackgroundCritical illness significantly impacts the well‐being of patients and families. Previous studies show that family members are willing to participate in patient care. Involving families in early mobility interventions may contribute to improved recovery and positive outcomes for patients and families.AimIn this scoping review, we investigated early mobility interventions for critically ill patients evaluated in randomized controlled trials and the extent to which family engagement in those interventions are reported in the literature.Study DesignIn this scoping review of reviews, EMBASE, CINAHL, PubMed and Cochrane Central databases were searched in October 2019 and updated in February 2022. Systematic reviews were included and assessed using A MeaSurement Tool to Assess Systematic Reviews (AMSTAR) 2. Data were synthesized using a narrative approach. PRISMA‐ScR guidelines were adhered to for reporting.ResultsThirty‐three reviews were included which described a range of early mobility interventions for critically ill patients; none explicitly mentioned family engagement. Almost half of the reviews were of low or critically low quality. Insufficient detail of early mobility interventions prompted information to be extracted from the primary studies.ConclusionsThere are a range of early mobility interventions for critically ill patients but few involve families. Given the positive outcomes of family participation, and family willingness to participate in care, there is a need to explore the feasibility and acceptability of family participation in early mobility interventions.Relevance to Clinical PracticeFamily engagement in early mobility interventions for critically ill patients should be encouraged and supported. How to best support family members and clinicians in enacting family involvement in early mobility requires further investigation.

Published: September 2023

BackgroundPelvic ring disruption (PRD) is a serious trauma associated with high mortality and disability rates. Poor reduction can lead to complications such as pelvic deformity and delayed fracture healing. Here, we introduce a new technology using mixed reality surgical navigation (MRSN) with an unlocking closed reduction technique (UCRT) frame to assist pelvic fracture reduction and fixation.MethodsThirty patients with PRD were enrolled in this study. All of the patients underwent preoperative CT scans, with the pelvis and tracker segmented into three‐dimensional models. Under MRSN guidance, auxiliary reduction screws were inserted to grasp the pelvic bone. An ideal trajectory for closed reduction was planned, and suitable CS screws were used for stable fixation after good reduction. Operation time, fluoroscopy frequency, and both Matta and Majeed scores were analyzed.ResultsThe mean follow‐up period was 10.8 months (7.5, 12.25 months) (range 6–24 months). The average duration of operation was 212.5 min (187.5, 272.8 min) (range 133–562 min), and the average reduction time was 23.0 min (15.0, 42.5 min) (range 10–70). The average fluoroscopy frequency was 34.0 times (31.5, 52.5 times) (range 23–68 times). One hundred and fifty screws were successfully inserted on the first attempt. All the fractures healed well with no complications. Excellent reduction quality (Matta score ≤4 mm) was achieved in 29/30 cases, and good reduction quality (Matta score between 4 and 10 mm) was achieved in 1/30 cases. All patients achieved bone healing after an average of 4.0 months (3.5, 5.9 months) (range 3–6), as well as good function recovery with an average Majeed score of 91.0 (87.8, 95.0) (range 71–100).ConclusionThe MRSN technique described improved reduction accuracy and radiation exposure without considerable extension of operation time.
