Authors: Hébert-Losier Kim , Boswell-Smith Caleb , Hanzlíková Ivana 
Published: August 2023

Background Assessing individuals in their own athletic footwear in clinics is common, but can affect movement, performance, and clinical measures. Purpose The aim was to compare overall Landing Error Scoring System (LESS) scores, injury risk categorization, specific LESS errors, and jump heights between habitual athletic footwear and barefoot conditions. Study design Randomized cross-over laboratory study. Methods Eighty healthy individuals (55% male) completed the LESS following standard procedures (i.e., land from a 30-cm box to a distance of 50% of body height and then jump upwards maximally). Participants performed the LESS three times in two randomized conditions: footwear and barefoot. LESS data were extracted from 2D videos to compare group-level mean LESS scores, group-level and individual-level injury risk categorization (5-error threshold), specific landing errors, and jump heights between conditions. Results LESS scores were significantly greater (0.3 errors, p=0.022) and jump heights were significantly lower (0.6 cm, p=0.029) in footwear than barefoot, but differences were trivial (d = 0.18 and -0.07, respectively) and not clinically meaningful. Although the number of high injury-risk participants was not statistically different at a group level (p=1.000); 27 individuals (33.8%) exhibited a clinically meaningful difference between conditions of one error or more in LESS score, categorization was inconsistent for 16.3% of individuals, and four of the 17 landing errors significantly differed between conditions. Conclusion At a group level, habitual athletic footwear does not meaningfully influence LESS scores, risk categorization, or jump height. At an individual level, footwear can meaningfully affect LESS scores, risk categorization, and alter landing strategies. Use of consistent protocol and footwear is advised for assessing movement patterns and injury risk from the LESS given the unknown predictive value of this test barefoot. Level of Evidence Level 3.

Published: August 2023

Background Balance and postural stability are required of figure skaters throughout on-ice performance. Spinning, jumping, and landing each rely on this skill set to maintain control while skaters manage changing demands for each skating discipline. Hypothesis/Purpose The aim of this study was to compare balance error scoring system (BESS) performance in figure skaters between disciplines and determine if age was related to BESS performance. Study Design Cross-sectional study. Methods Three hundred and fifty-eight figure skaters (age: 15.4±3.3 years, 213 females, 145 males) of multiple disciplines completed the BESS during the United States Figure Skating’s Standardized Testing of Athleticism to Recognize Skaters (S.T.A.R.S.) combine. Errors during each condition of the BESS were recorded by trained evaluators. A 3x6 ANOVA was used to determine BESS differences based on skating discipline. Spearman’s rho (ρ) correlation coefficients were calculated for relationships between BESS errors and age. Results Ice dancers had more errors than singles and pairs for bipedal foam (p<0.001) but had fewer errors than single skaters for single leg foam (p=0.002). Tandem on a firm surface also showed an increase in errors for ice dancers and pairs skaters compared to singles (p<0.001). There were significant weak negative relationships noted between age and bipedal foam and single leg firm conditions (ρ=-0.14, -0.23, p<0.05). Conclusion Figure skaters of different disciplines have varying levels of static postural stability. Assessing postural stability in figure skaters can provide insight to improve performance and may identify skaters at risk of injury. Level of Evidence 3

Background Weightlifting is growing in popularity among recreational and competitive athletes. The barbell back squat (BackS) is commonly included in these training programs, while the barbell front squat (FrontS) is commonly performed as a component of other lifts such as the power clean or clean and jerk, it is less commonly practiced in isolation. Hypothesis/Purpose The purpose of this study was to examine the effects of VPAC performance on trunk muscle and LE biomechanical responses during loaded BackS versus FrontS in healthy subjects. Study Design Controlled Laboratory Study Methods Healthy male subjects with the ability to perform a sub-maximal loaded barbell squat lift were recruited. Subjects completed informed consent, demographic/medical history questionnaires and an instructional video. Subjects practiced VPAC and received feedback. Surface electromyography (sEMG) electrodes and kinematic markers were applied. Muscles included were the internal oblique (IO), external oblique (EO), rectus abdominis, iliocostalis lumborum (ICL), superficial multifidi, rectus femoris, vastus lateralis, biceps femoris, and gluteus maximus. Maximal voluntary isometric contractions established reference sEMG values. A squat one-rep-max (1RM) was predicted by researchers using a three to five repetition maximum (3RM, 5RM) load protocol. Subjects performed BackS trials at 75% 1RM while FrontS trials were performed at 75% BackS weight, both with and without VPAC. Subjects performed three repetitions of each condition with feet positioned on two adjacent force plates. Significant interactions and main effects were tested using a 2(VPAC strategy) x 2(squat variation) and 2(VPAC strategy) x 2(direction) within-subject repeated measures ANOVAs. Tukey’s Post-Hoc tests identified the location of significant differences. Results Trunk muscle activity was significantly higher during FrontS versus BackS regardless of VPAC condition. (IO: p=0.018, EO: p<0.001, ICL: p<0.001) VPAC increased performance time for both squat variations (p=.0011), which may be associated with decreased detrimental force potential on the lumbar spine and knees. VPAC led to improved ability to maintain a neutral lumbar spine during both squat variations. This finding is associated with decreased detrimental force potential on the lumbar spine. Conclusions Findings could help guide practitioners and coaches to choose squat variations and incorporate VPAC strategies during their treatments and/or training programs. Level of Evidence Level 3

Published: August 2023

Background The two-dimensional (2D) video-analysis of the change of direction (COD) technique has never been used to attempt to predict the risk of ACL injury in female football players. Hypothesis/Purpose The purpose of the present pilot study was to prospectively investigate the biomechanical predictors of ACL injury during a COD task in female football players using both gold standard 3D motion capture and a qualitative scoring system based on 2D video-analysis. Study Design Prospective cohort study Methods Sixteen competitive female football (soccer) players (age 21.4 ± 4.3) performed a series of pre-planned 90° COD tasks. 3D motion data was recorded through 10 stereophotogrammetric cameras and a force platform. 2D frontal and transverse plane joint kinematics were computed through video-analysis from three high-speed cameras. A scoring system based on five criteria was adopted: limb stability, pelvis stability, trunk stability, shock absorption, and movement strategy. The players were prospectively followed for the next two consecutive football seasons and the occurrence of severe knee injuries was registered. Results Four players (25%) experienced an ACL injury. In 3D analysis, ACL-injured players showed greater knee valgus, knee internal rotation, and lower knee flexion (p= 0.017 – 0.029). Lower hip flexion coupled with greater external rotation (p= 0.003 – 0.042), ankle eversion, and contralateral pelvic drop (p<0.001) were also noted. In 2D analysis, ACL-injured players showed greater internal foot rotation, contralateral pelvic drop, lower knee flexion, and contralateral trunk tilt (moderate-to-large effect size). Pelvis stability and trunk stability showed the highest predictive value towards ACL injury. Total score was significantly lower in ACL-injured players with a moderate effect size (d=0.45). Conclusions Both 3D and 2D methodologies depicted biomechanical risk factors and offered predictive insights towards the ACL injury risk. Awareness should rise in women’s football regarding the high risk of ACL injury and the strategies to assess and mitigate it. Level of Evidence 3

Published: August 2023

Purpose: The integrated reporting (IR) process allows companies to present their business in a clear and concise manner. It was intended to investigate whether corporate disclosures are more beneficial when integrated reporting is adopted.

Theoretical framework: According to agency theory, market value of shares can be increased by providing investors with more concise, useful and relevant information. Integrated reporting which is the most recent advancement in the realm of corporate reporting facilitates to growing information needs of stakeholders. Thereby, this study examines whether integrated reporting enhance the value relevance of corporate disclosures which enhance the market value of firm.

Design/Methodology/Approach: This study was conducted using data collected from Colombo Stock Exchange (CSE) listed companies. There were 121 companies included in the sample, representing each sector proportionately. The data was gathered from corporate annual reports from 2012 to 2019. In the analysis, the return model and price model were both used. Descriptive statistics, correlation and panel regression analysis were conducted for achieving the research objectives.

Findings: The study discovered that Sri Lankan-listed companies had a low level of corporate disclosures, although it has improved significantly over time. Further, results of the study revealed that increasing the level of disclosures in annual reports had no significant impact on improving the firm value, indicating that there is no any value relevance of disclosures. Finally, it also concluded that the IR is not enhancing the value relevance of corporate disclosures.

Research, practical and social implications: The study suggest that financial managers should encourage in communicating more timely and more relevant information in order to increase their market capitalization which represent the value relevance. Further financial reporting guidelines and practices need to be more regulated. At the same time this study highlights the importance of implementing innovative corporate reporting techniques to enhance investor confidence, thereby stimulating economic growth and benefiting a wider range of stakeholders.

Originality/Value: Many researchers have investigated whether integrated reporting enhance the value relevance of accounting information. Still, existing research on the value relevance of corporate disclosures has not extensively explored the effects of adopting integrated reporting (IR) on this aspect.

Typecast! Some lessons from Norwegian public anthropology
Authors: Kolshus Thorgeir 
Published: August 2023

After many years of slumber, a string of disturbing political developments and setbacks in many parts of the world have convinced the anthropological community to recommit to its public role. As one of a mere handful of nations where anthropology has had a longstanding presence in public debates, Norway serves as an example for others to follow. In this essay, I use my experiences from years of varied media engagements to make the case for a public anthropology that is not merely a one-way enlightenment project but a tool for reflexivity and disciplinary critique. The didactic reformulation required when reaching out to new audiences can defamiliarise the things we know well and help us see things anew. In addition, the feedback, and occasionally outright resistance, often harvested by such outreach can provide a fresh take on established patterns of thinking and identify thematic and analytic blind spots. In Norway, anthropologists have gradually become collectively branded as belonging to the political left, which has blunted the potential impact of an anthropological critique. Showing that this branding is not entirely without substance, I argue that, by using media engagements as a two-way source of reflexivity, public anthropology can be a vital part of the discipline’s epistemological agility.

Proses manufaktur PCB melibatkan banyak proses salah satunya yaitu Surface finishes. Salah satu jenis Surface finishes yang biasa digunakan yaitu Immersion tin. Immersion tin adalah salah satu proses Surface finishes yang menggunakan timah murni pada prosesnya. Immersion tin berfungsi melindungi tembaga dari oksidasi dan membuat permukaan tembaga atau pad mudah disolder. Kebersihan pad dan ketebalan hasil Immersion tin mempengaruhi kualitas PCB yang dihasilkan. Oleh karena itu peneliti melakukan evaluasi kualitas hasil proses Immersion tin dengan menggunakan metode DOE (Design of Experiment). Dimana metode ini dapat membantu dalam menentukan parameter yang optimal. Untuk Variabel yang digunakan yaitu Storage Time After Microetch dan Immersion in tin Bath. Dalam proses penelitian didapatkan PCB mengalami perubahan morfologi pada 23 jam setelah disimpan di storage. Hal tersebut disebabkan oleh adanya kelembapan yang masih terdapat pada PCB akibat dari kurang maksimal pada saat proses pengeringan (drying). Pada penelitian ini Solder Coating Thickness yang optimal pada sampel ke-14 dengan hasil sebesar 4.59 µm dan dengan parameter Storage Time After Microetch selama 50 menit dan Immersion in tin Bath selama 120 menit. Untuk kebersihan pad yang paling optimal terdapat pada sampel ke-5 dan ke-12 dengan parameter Storage Time After Microetch selama 30 menit dan 60 menit dan ditandai dengan tidak adanya kontaminan pada pad tersebut. Selain itu juga, Pada penelitian ini terdapat hasil mapping yang kurang optimal ditandai dengan hanya terdapat 1 bagian dari 1 sampel yang terkandung timah dari 16 sampel pengujian. Sampel tersebut yaitu sampel ke-3 dengan parameter Storage Time After Microetch selama 10 menit dan Immersion in tin Bath selama 55 menit dengan kandungan tin yaitu 91.9 %.
Estimation of Attenuation Coefficient Values Using Remote Sensing and Its Relationship With Shallow Water Depth
Authors: Tiarasani Anggi , Siregar Vincentius Paulus , Gaol Jonson Lumban 
Published: August 2023

In ocean remote sensing, the intensity of light entering the water column decreases exponentially with increasing depth due to scattering and particle absorption in the water column. This process of decreasing light intensity is called attenuation. Attenuation is a limiting factor in detecting objects in the water column and seafloor using remote sensing, which relies on light intensity. The attenuation coefficient (Kd) is an important optical property of seawater as it provides information about water clarity and the level of light attenuation. This study aims to analyze the estimation of the attenuation coefficient values and their variability using in-situ measurements and Sentinel-2 level 2A data in Karang Lebar, Pulau Panggang, and Pulau Air, in the Seribu Islands Regency, North Jakarta. We tested several algorithms to estimate the attenuation coefficient values. The research results show that the in-situ Kd and the estimated model values have a good correlation (r = 0.75-0.86). The distribution of attenuation coefficient values in the shallow waters of the study area ranges from 0.06 to 0.18m-1. The accuracy of estimating shallow water depth at the study sites was best represented by R2 and RMSE values in the range of 0-5m with an attenuation coefficient of 0.06-0.11m-1.
