Coopetitive service innovation: the role of geographical proximity, innovation focus and customer cooperation
Authors: Virtanen Henrik , Björk Peter 
Published: October 2024

Purpose
Previous research on the impact of coopetition on innovation performance has provided contradictory results. Thus, this study aims to fill the gap by gathering data to explain the impact of coopetition on service innovation, considering the partners’ geographical proximity, innovation focus of the firm and cooperation with customers.

Design/methodology/approach
A logistic regression model is applied, and four hypotheses are tested using data from the Eurostat Community Innovation Survey 2018. The cross-sectional data set consists of 13,723 firms innovating services in selected European Union countries.

Findings
The findings verify the importance of coopetition for service innovation. However, the coopetitive partners’ nationality does not have a significant impact. Furthermore, the integration of customer cooperation with coopetition enhances service innovation. Hence, competing partners seem not to avoid cooperation in output functions near the customers. To coopete in innovation is risky, but the findings reveal that partners develop novel services through coopetition, intended to produce a higher return to compensate for the risks.

Originality/value
Presumably, this is one of the first large-scale studies examining the impact of coopetition on service innovation in a European context. This study indicates that coopetition amplifies service innovation, thus reducing the divergent views on the impact of coopetition on innovation performance. It responds to the request for more research on the context of coopetitive innovation by explaining how the firms’ geographical proximity, innovation focus and cooperation with customers impact their service innovation performance.

Purpose
This study aims to analyse cellulose fibres extracted from the pseudo-stems of Cymbopogon citratus and evaluate their properties in non-woven fabric production.

Design/methodology/approach
The water retting method was used for fibre extraction, and intrinsic fibre qualities were examined to assess their suitability for textile applications. A thermal bonding technique, using a hot press machine and polylactic acid powder as a binder, was applied for non-woven fabric development.

Findings
The retted fibres had an average length of 156 mm and a fineness value of 5.73 tex. The fibre’s tenacity and elongation values were 1.33 gf/denier and 12.78%, respectively. Fourier transform infrared analysis confirmed the presence of major cellulose components. The fibre’s crystallinity and friction coefficient were 50% and 0.3, respectively. C. citratus fibre exhibited hygroscopic characteristics with a moisture regain of 10.65%. Experimental non-woven fabrics (70% C. citratus fibre, 30% polylactic acid powder) demonstrated consistent weight and thickness, with variations in tensile strength. Moisture regain values for non-woven fabrics were approximately 7.6%.

Originality/value
The features of C. citratus fibre, obtained with the water retting process, exhibited suitability for textile applications. Three experimental non-woven fabrics comprising of C. citratus fibre and polylactic acid powder were produced with three different pressing temperatures. The tensile strength properties of these fabrics were influenced by pressing temperature.
Do gender quotas increase political knowledge?
Authors: VENTURINI GIULIA 
Published: October 2024

AbstractDo gender quotas increase political knowledge? While some studies suggest that quotas can positively impact women's political engagement and participation, others find null or negative effects. This paper focuses on Western Europe and argues that the implementation of quotas serves as an attention and consciousness‐raising event, potentially enhancing awareness of the political sphere. To investigate this, I propose a novel research design that capitalizes on the (quasi) exogenous shock resulting from the introduction of gender quotas. By influencing symbolic representation, quotas may enhance women's sense of empowerment, equality and willingness to engage in politics. Furthermore, the impact is expected to be more pronounced among younger women due to the heightened political socialization experienced during adolescence. Thus, the institutional change brought about by quotas is anticipated to particularly boost political knowledge among (younger) women and subsequently narrow the gender gap. To examine this hypothesis, I analyse data from 1992 to 2018 from 12 countries, of which six implemented gender quotas. Using a hierarchical Bayesian model, I assess respondents' answers to knowledge questions. The findings indicate that the introduction of gender quotas in parliamentary systems has a positive effect on reducing the gender gap in political knowledge among younger individuals, while the effects are statistically insignificant for older citizens.

Published: October 2024

AbstractIn this work, wine vinegars macerated with figs under different conditions have been characterized for the first time. Samples were analyzed by solid phase microextraction and gas chromatography coupled to mass spectrometry, sensory and physicochemical analysis. The results revealed that fig maceration of wine vinegars influenced the physicochemical, sensory, and volatile profiles of the final product, which were mainly affected by the fig amount (10, 20 or 30%), the fig type (fresh or dry) and the base wine vinegar (young or aged) used, and to a lesser extent the way the fig was added (crushed or chopped). The maceration, regardless the conditions used, increased the fruity notes, overall taste and visual impression, the tonality, total polyphenols and sugar content, and the presence of some volatile compounds, mainly terpenes and ketones, such as (Z)‐p‐mentha‐2,8‐dien‐1‐ol, or β‐damascenone. Therefore, maceration increased the organoleptic complexity, which could enhance the acceptability of consumers towards these products.Practical ApplicationThis research studied how wine vinegars macerated with figs affect in different ways their taste, smell, and chemical properties. Thus, the results showed that these wine vinegars made with fig maceration by using different amounts and types of figs, as well as the type of vinegar used, changed their characteristics, making them smell and taste fruitier and more pleasant. This could be useful for making better‐tasting and more appealing vinegars for consumers who enjoy unique and enhanced flavors in their food.

Published: October 2024

AbstractThe protein structure, gel changes, and chewing properties of low‐sodium myofibrillar protein (MP) prepared by compound chloride salts (KCl/MgCl2, KCl/CaCl2, and KCl/MgCl2/CaCl2) and different substitution degrees (10%, 25%, and 40%) at same ionic strength (0.6 M) were investigated. The results revealed that the low‐sodium MP gels containing CaCl2 manifested more liquid loss and less moisture content accompanied by obvious morphological shrinkage, while KCl/MgCl2 contributed to the gel juiciness. At high substitution degree of 40%, KCl/CaCl2 substitution rendered the gel with dense structure and highest strength, but worse water retention capacity. Using other compound chloride salts influenced the chewing efficiency, and CaCl2 substitution made the gel relatively hard to chew. The inhomogeneous structure accompanied by cluster blocks in KCl/CaCl2‐substituted MP gel accelerated the overall fracture rate. During heating process, more proteins in CaCl2‐substituted MP did not participate in gel formation, intervening the final gel properties. The chloride salt mixtures containing MgCl2, rather than CaCl2, avoided or alleviated the liquid loss and shrinkage of low‐sodium MP gel within the substitution degree of 10%–40%, and substitution degree not exceeding 25% was more reasonable for the controlled qualities.
Sedimentary Expressions of the Early Jurassic Jenkyns Event in an Inland Lacustrine System in the Yin'gen–Ejinaqi Basin, North China

Published: October 2024

AbstractThe Jenkyns Event, more widely known as the Toarcian Oceanic Anoxic Event (T‐OAE), is marked by globally distributed negative carbon‐isotope excursions, widespread oxygen depletion, and large‐scale organic carbon burial, which indicate major climate/environmental perturbations in Earth's surface systems during the Early Jurassic. Although extensive research has been conducted in European continental settings, particularly in the western peri‐Tethys regions, the impacts of this event beyond Europe remains largely unexplored. Here, a multiapproach study including investigations into the spore‐pollen assemblages, pyrite framboids, clay minerals, total organic carbon (TOC) levels, and organic carbon isotope (δ13Corg) levels in a lacustrine borehole section (MED1) from the Yin'gen–Ejinaqi Basin, North China, provides evidence of the occurrence of the Jenkyns Event and its extensive sedimentary responses in the eastern Tethys terrestrial systems. Two distinct spore‐pollen assemblages have been identified in MED1 (drilling depth: 982.4 m to 1267.5 m), with the Cycadopites–Protopinus–Osmundacidites assemblage in the lower part (1267.5 m to 1132.9 m) indicating a middle Early Jurassic age and the Classopollis assemblage in the upper part (1132.9 m to 985.7 m) suggesting a Toarcian age. Framboidal pyrite data suggest more anoxic conditions during the deposition of black mudstone and shale intercalations in the lower part of the Classopollis assemblage (1132.9 m to 1066.9 m), which combined with organic carbon enrichment and negative δ13Corg excursions, are considered the paleoenvironmental response to the Jenkyns Event in the study area. Furthermore, the evolution of vegetation groups changed from plant groups characterized by bisaccate and cycad pollen, as well as fern spores, to vegetation groups represented by Cheirolepidiaceae pollen across the Jenkyns Event, as evidenced by spore‐pollen data, together with the clay mineral assemblage change characterized by a notable increase in illite at the expense of kaolinite, suggests that while a subtropical‐temperate climate persisted, a change toward warmer and drier conditions most likely occurred in the early Toarcian in the study area. In contrast to the humidification evidenced in many coastal settings, this aridification trend in the Yin'gen–Ejinaqi Basin aligns with the conditions in many inland areas. It is hypothesized that the underlying cause of these divergent changes may be linked to certain patterns of spatially variable water availability on land, potentially driven by extremified hydrological conditions.

AbstractIntroductionPemetrexed is a key therapeutic agent for advanced non‐squamous non‐small cell lung cancer (Nsq‐NSCLC), yet it is associated with renal toxicity. This study aims to elucidate the incidence, risk factors, and survival impact of renal injury in patients with Nsq‐NSCLC treated with pemetrexed.MethodsWe conducted a retrospective study including 136 patients with Nsq‐NSCLC treated with pemetrexed. Data on demographics, renal function, progression‐free survival (PFS), and overall survival (OS) were collected. Renal injury was defined as a reduction above 25% in estimated glomerular filtration rate (eGFR) from baseline. Its associated risk factors were analyzed using logistic regression, and impact on survival was analyzed using log‐rank test. The creatinine clearance rate (CCr) was calculated, and a CCr < 45 mL/min served as a contraindication for continuing pemetrexed.ResultsThe study found a 31.6% (43/136) incidence of renal injury, with 9.6% (13/136) having CCr < 45 mL/min and discontinuing pemetrexed. Univariate and multivariate analyses identified factors significantly associated with increased renal injury risk including older age, use of cisplatin, and higher number of pemetrexed cycles. The patients with renal injury had a median PFS (mPFS) of 13.5 months and a median OS (mOS) of 36.0 months, while the patients without had an mPFS of 9.0 months and an mOS of 35.0 months, and these differences were not statistically significant.ConclusionRenal injury is a considerable complication in patients with Nsq‐NSCLC undergoing pemetrexed treatment, with age, platinum type, and pemetrexed treatment cycles as key risk factors. These findings highlight the necessity for careful renal monitoring in this patient population.

AbstractBackgroundSurgical bootcamps provide hands‐on learning opportunities for junior doctors and trainees in low‐pressure, non‐clinical environments. Participants develop skills, knowledge, and confidence in preparation for their registrar years. A number of international urology‐specific bootcamps have demonstrated improvements in these technical and non‐technical domains. However, there was no such opportunity for Australian doctors. In the first urology bootcamp in Australia, we aimed to assess participants' knowledge, technical skills, and confidence in managing urological conditions pre‐ and post‐bootcamp.MethodsTwenty‐five early‐career medical officers attended the bootcamp and completed a comprehensive written survey at the beginning and end of the bootcamp.ResultsResults showed that self‐perceptions of knowledge, confidence, and technical skill all improved at the conclusion of the bootcamp (P = 0.01). All participants reported the bootcamp to be ‘useful’ or ‘very useful’ in furthering their urological training.ConclusionThis study demonstrates the success of an inaugural Australian urology bootcamp in preparing junior doctors and unaccredited registrars for their registrar training years.

AbstractLittle is known about how discrimination contributes to health behaviors in childhood. We examined the association between children's exposure to discrimination and their snacking behavior in a sample of youth of color (N = 164, Mage = 11.5 years, 49% female, 60% Black, 40% Hispanic/Latinx). We also explored whether children's body mass index (BMI) or sleepiness moderated the association between discrimination and calorie consumption. The significant link between discrimination and calorie consumption was moderated by children's BMI, such that discrimination was associated with calorie consumption for children with BMI percentiles above 79%. Children's sleepiness did not serve as an additional moderator. Efforts to promote health should consider children's broader socio‐contextual experiences, including discrimination, as factors that may shape eating patterns.

Published: October 2024

ABSTRACTIntroductionTreatment‐resistant depression (TRD) is a condition in which patients suffering from depression no longer respond to common methods of treatment, such as anti‐depressant medication. Neurosurgical procedures such as ablative surgery, deep brain stimulation, and vagus nerve stimulation have been used in efforts to overcome TRD.ObjectivesThis review aims to provide an overview of the side effects of neurosurgery performed in clinical studies related to depression.MethodsA literature search was conducted through PubMed, MEDLINE, EMBASE, Ovid, and ClinicalTrials.gov databases.ResultsThis review selected 10 studies for ablative surgery, 12 for deep brain stimulation, and 10 for vagus nerve stimulation, analyzing their side effect profiles of neurosurgery for TRD. The major side effects of each type of neurosurgery were identified, such as incontinence and confusion for ablative surgery, headaches and increased suicide ideation for deep brain stimulation, and voice hoarseness and dyspnea for vagus nerve stimulation.ConclusionThe review discusses the merits and demerits of neurosurgery as a treatment option for TRD. It also suggests new insights into decreasing the burden of these neurosurgical side effects so that they can be a viable, high‐efficacy treatment method for TRD.

Published: October 2024

SummaryA cross‐sectional, online survey was conducted in the United Kingdom, France, Germany, and the United States (14 November–22 December 2022) to investigate preferences for anti‐obesity medication (AOM) among people with obesity (PwO) and healthcare providers (HCPs). Eligibility: Adult PwO who self‐defined their body type as overweight/obese, were trying to lose weight and had BMI ≥30.0 or 27.0–29.9 kg/m2 with ≥1 obesity‐related complication; HCPs had to see ≥30 PwO in a typical month and be a decision‐maker regarding their weight loss. The survey included 2500 PwO and 500 HCPs. Exercise (96%) and diet (90%) were the most common weight management methods; AOM use was low (8%). Key barriers to use of prescribed AOMs among PwO were not wanting to take AOM (34%), side effects concerns (33%), and not trusting AOM (26%). Most HCPs (79%) had prescribed/recommended AOMs. Efficacy was the most common reason for preferring one of the shown product profiles among PwO (60%) and HCPs (86%); improving cardiovascular risk was also important to 95% of HCPs when deciding which AOM to prescribe. AOM preference is largely driven by efficacy. Increasing knowledge could help to address barriers to AOM use and improve outcomes for PwO.

SummaryWe aimed to examine the effects of isocaloric fructose restriction on adipose tissue distribution and serum adipokines. Individuals with BMI >28 kg/m2 (n = 44) followed a 6‐week fructose‐restricted diet and were randomly allocated to (double‐blind) oral supplementation with fructose (control) or glucose (intervention) powder three times daily. Visceral (VAT) and subcutaneous (SAT) adipose tissue was quantified with MRI. Serum interleukin 6 and 8, tumour necrosis factor alpha and adiponectin levels were measured with sandwich immunoassay. BMI decreased in both groups, but the change did not differ between groups (−0.1 kg/m2, 95%CI: −0.3; 0.5). SAT decreased statistically significantly in the control group (−23.2 cm3, 95%CI: −49.4; −4.1), but not in the intervention group. The change in SAT did not differ between groups (29.6 cm3, 95%CI: −1.2; 61.8). No significant differences in VAT were observed within or between study arms. The VAT/SAT ratio decreased statistically significantly in the intervention group (−0.02, 95%CI: −0.04; −0.003) and the change was significantly different between groups (−0.03, 95%CI: −0.54; −0.003). Serum adipokine levels were not affected by the intervention. This study shows that a fructose‐restricted diet resulted in a favourable change in adipose tissue distribution, but did not affect serum adipokines. Further studies are warranted to clarify the underlying mechanisms how fructose affects adipose tissue distribution.

Published: October 2024

ABSTRACTResearch Question/IssueWe examine the relationship between CEOs' industry tournament incentives (CITI) and stock liquidity in the United States. We also examine if the effect of CITI on stock liquidity varies depending on the information‐asymmetry and corporate governance mechanisms.Research Findings/InsightsWe find that firms with stronger CITI are associated with greater stock liquidity. Exploiting the enforceability of executive noncompetition agreements across the states in the United States as a quasi‐natural experiment, we find that firms headquartered in states that introduce these agreements on average experience lower stock liquidity, suggesting a causal relation. We also find that the effect of CITI on stock liquidity is stronger among firms with severe information‐asymmetry problems, but weaker among firms with strong governance mechanisms.Theoretical/Academic ImplicationsWe extend research that examines the impacts of CEO industry tournament incentives on corporate outcomes and strategies. Our paper shows that CEO industry tournament incentives matter for stock liquidity. Our paper contributes to a large literature on the roles of CEO styles and behaviors in shaping corporate policies.Practitioner/Policy ImplicationsOur findings have several practical implications for investors, policymakers, and financial analysts. For example, our findings can help investors better understand how CEOs' compensation‐based incentives impact stock liquidity. Similarly, policymakers can use our findings to design policies that encourage CEOs to act in the best interest of their shareholders and promote market efficiency.
