Open innovation strategy is a new paradigm strategy where a firm purposefully incorporates and integrates knowledge developed outside the firm's boundary for its internal R&D and innovation projects. One important variation of open innovation is crowdsourcing in which solutions are sought from a bigger pool, not only from external firms, but also individual specialists and sometimes users. While increasing attention has been paid to crowdsourcing as a way to incubate innovative ideas, facilitate creativity, and to develop firms' product and service offerings, systematic academic understanding is still lacking concerning how specifically crowdsourcing can be implemented. Based on the March's exploration and exploitation framework, the current study analyzes and categorizes different models of crowdsourcing. In particular, we identify three variations of the ways crowdsourcing can be used in terms of whether a firm's objective of using crowdsourcing is oriented toward idea generation, problem solving, or both. The results of this study would also provide valuable information for managers to choose a business model of crowdsourcing that aligns the best with a specific stage and a goal of a firm's innovation efforts.
ETHNIC-INSPIRED DESIGN (EID) CONSUMPTION: A MEANS OF ENHANCING SELF-VIEW CONFIDENCE

Despite the growing trend of incorporating ethnic motifs, colors, and styles (i.e., ethnic-inspired designs (EIDs)) into mainstream fashion products in the US, there is yet a lack of understanding on what drives consumers to demand such products with EIDs. Although extant literature provides important insights as to what motivates consumers to favor EIDs, much of the studies have focused on the products’ appeals to particular ethnic groups with matching their cultural backgrounds. Less is understood on the core self-centric values mainstream consumers reflect into EIDs and the personal goal-pursuit they project by wearing them. We address this issue. Building upon Image Theory (Beach & Mitchell, 1987), our findings document that consumers’ purchase intent toward products with EIDs is more fundamentally driven by their aspirations to boost their self-view confidence by wearing EIDs (i.e., self-enhancement), which are guided by their core self-values that are represented by two personal values (i.e., cultural openness and seeking personal style) and two product values (i.e., perceived esthetics and perceived novelty).

Objective: The aim of this study was to investigate the association between the use of statins and the occurrence of delirium in a large cohort of patients in the intensive care unit (ICU), considering disease severity and statin properties. Methods: We obtained clinical and demographical information from 3,604 patients admitted to the ICU from January 2013 to April 2020. This included information on daily statin use and delirium state, as assessed by the Confusion Assessment Method for ICU. We used inverse probability of treatment weighting and categorized the patients into four groups based on the Acute Physiology and Chronic Health Evaluation II score (group 1: 0−10 - mild; group 2: 11−20 - mild to moderate; group 3: 21−30 - moderate to severe; group 4: > 30 - severe). We analyzed the association between the use of statin and the occurrence of delirium in each group, while taking into account the properties of statins. Results: Comparisons between statin and non-statin patient groups revealed that only in group 2, patients who were administered statin showed significantly higher occurrence of delirium (p = 0.004, odds ratio [OR] = 1.58) compared to the patients who did not receive statin. Regardless of whether statins were lipophilic (p = 0.036, OR = 1.47) or hydrophilic (p = 0.032, OR = 1.84), the occurrence of delirium was higher only in patients from group 2. Conclusion: The use of statins may be associated with the increases in the risk of delirium occurrence in patients with mild to moderate disease severity, irrespective of statin properties.
Negative Mood States Correlate with Laterobasal Amygdala in Collegiate Football Players

<P>A number of studies have suggested that sports-related concussion (SRC) may place individuals at increased risk for depression and negative outcomes including suicide. However, the mechanisms underlying a potential relationship between brain integrity and mood remain unclear. The current study is aimed at examining the association between amygdala shape, mood state, and postconcussion symptoms in collegiate football players. Thirty members of 1 football team completed the Profile of Mood States (POMS), the postconcussion symptom scale (PCSS), and an MRI protocol during preseason camp. T1-weighted images were acquired and three-dimensional amygdala and probabilistic maps were created for shape analysis. Correlation analyses between POMS and PCSS and the relationship between POMS and amygdala shape were completed. In the amygdala, the left laterobasal subregion showed a positive relationship with the POMS total score and subscales scores. No significant relationship between PCSS and amygdala shape was found. Significant positive correlations were found between POMS subscales and PCSS. These results indicate that amygdala structure may be more closely associated with negative mood states than postconcussion symptoms. These findings suggest that premorbid individual differences in effect may provide critical insight into the relationship between negative mood and outcomes in collegiate football players with SRC.</P>

The recent reverse total shoulder arthroplasty (TSA) implant designs employ shorter humeral component stems; some designs even eliminate the stem completely. The short stem provides several advantages: preserved bone, less stress shielding, ease of revision surgery, and freedom of humeral component location due to the minimal stem length and noncomplex shape. However, due to the reduction in contact surface and frictional fixation, this stemless design may cause failure of the implant, especially during early stages following surgery. In this study, the effect of fin shape and fin length of stemless humeral components were investigated, and hypothesis was that stress and micromotion would decrease as the ratio of fin length to baseplate radius increases and the overall size of the humerus component increased. 15 different 3D models of stemless humeral components, 5 different lengths and 3 different shapes, within reverse TSA systems were developed. Each humerus component was analyzed using finite element analysis (FEA) to investigate the effects of stem length and fin shape on the initial stability of the component. The highest stress and micromotion were observed at the shortest fin length; lowest stress and micromotion were found at the longest fin length. Results suggest that the length of the fin affects the stress at the bone as well as the amount of micromotion; 20-30 % longer fin length than baseplate radius would be ideal for the stemless humeral component design. However, the various fin shapes showed mixed effects on the results and further investigation is required.
