Purpose
The purpose of this paper is to examine how firms can develop business risk resilience from supply chain disruption events, by developing big data analytics (BDA) capabilities within their ...organization. The authors test whether BDA mediates the impact of institutional response to supply chain disruption events, and information technology infrastructure capabilities (ITICs), on firm’s ability to develop risk resilience from supply chain disruption events.
Design/methodology/approach
The study is based on survey data collected from 225 firms, spread across several sectors in the USA and Europe. The respondents are primarily senior and middle management professionals who have experience within the information technology (IT) and supply chain domain. Validity and reliability analyses were performed using SPSS and AMOS; and covariance-based structural equation modeling was used to test the hypothesis.
Findings
The analysis reveals two significant findings. First, the authors observe that institutional experience with managing supply chain disruption events has a negative impact on firm’s ability to develop business risk resilience. However, if the organizations adopt BDA capabilities, it enables them to effectively utilize resident firm knowledge and develop supply chain risk resilience capacity. The results further suggest that BDA positively adds to an organization’s existing IT capabilities. The analysis shows that BDA mediates the impact of ITIC on the organization’s ability to develop risk resilience to supply chain disruption events.
Originality/value
This study is one of the few works that empirically validate the important role that BDA capabilities play in enabling firms develop business risk resilience from supply chain disruption events. The study further provides a counterpoint to the existing perspective within the supply chain risk management literature that institutional experience of managing past supply chain disruption events prepares the organization to deal with future disruption events. This paper adds to our understanding of how, by adopting BDA capabilities, firms can develop supply chain risk resilience from disruption events.
Nontyphoidal salmonellosis is the leading reported foodborne illness in Florida. Although the diversity of Salmonella serotypes circulating in Florida has been identified, the geographical ...characteristics of the major serotypes are poorly described. Here we examined the geospatial patterns of 803 whole-genome sequenced Salmonella isolates within seven major serotypes (Enteritidis, Newport, Javiana, Sandiego, Braenderup, Typhimurium and I 4,5,12:i:-) with the metadata obtained from Florida Department of Health during 2017–2018. Geographically, the distribution of incidence rates varied distinctively between serotypes. Illnesses with Enteritidis and Newport serotypes were widespread in Florida. The incidence rate for Javiana was relatively higher in the north compared to the south. Typhimurium was concentrated in the northwest, while I 4,5,12:i:-, the monophasic variant of Typhimurium was limited to the south. We also evaluated space–time clustering of isolates at the zip code level using scan statistic models. Space–time clusters were detected for each major serotype during 2017–2018. The multinomial scan statistic found the risk of illness with Javiana was higher in the north and southwest in the fall of 2017 compared to other major serotypes. This serotype-specific clustering analysis will assist in further unpacking the associations between distinct reservoirs and illnesses with major serotypes in Florida.
In view of turbulent market responses, building resilient business models for global competitiveness is a crucial challenge for firms in emerging economies. This article examines how Indian firms can ...build resilient business models that can facilitate global competitiveness. The article presents a research model that defines requirements of domestic advantage. Key issues related to building a more responsive, resilient, and agile businesses in Indian context are discussed. To promote future research issues, the authors develop propositions that explain the relationships between relevant constructs. Using a single firm, extensive case study methodology, the authors illustrate the growth processes for domestic advantage and global competitiveness.
Temporomandibular joint ankylosis which is most frequently caused by
trauma, presents with restriction in mouth opening in early stages and
if children are the victim and not treated early, it ...presents with
growth retardation of the involved mandibular side. Various methods are
available for surgical correction. We have reviewed our experience with
the efficacy of different interpositional materials in post-traumatic
cases in our set up with special reference to temporal fascia over last
three years. Twenty seven patients with history of trauma, mostly fall
from height, have been studied. They were evaluated clinically and by
computed tomography (CT) scan, orthopantogram and x- ray lateral
oblique view. The most common age group was 10-15 years with mean 12.5
years and male to female ratio 1:2. Preoperative mouth opening (inter
incisor distance) was 1-2 mm in 17 cases and 2-4 mm in 10 cases. We
have used temporalis fascia in nine, costochondral graft in seven,
silastic sheets in five and T-plates in six cases. Post-operatively,
adequate mouth opening of 30-50 mm was observed in six months follow-up
and more than 50 mm at one year follow up in 21 cases out of which nine
cases have interpositional material as temporalis fascia alone. The
postoperative period was uneventful in all cases and none required
re-operation for recurrences. We conclude that interpositional
arthroplasty, especially with pedicled temporal fascia, is the best
method to prevent recurrences and establish good mouth opening and full
range of jaw movements.

The Florida Complaint and Outbreak Reporting System (FL-CORS) database is used by the Florida Department of Health's Food and Waterborne Disease Program as one of the tools to detect foodborne ...disease outbreaks (FBOs). We present a descriptive and spatial network analysis of FL-CORS data collected during 2015 to 2018. We also quantified FBOs that were investigated and confirmed because of a filed complaint and the etiological agents involved in these outbreaks. An increasing number of unique complaints filed in FL-CORS was observed during 2015 to 2018, with a sharp increase during 2017 to 2018 and a different seasonal pattern in 2018. The preferred mechanism of reporting varied by age group, with younger people more frequently filing complaints online and older people preferring reporting in person or by phone. Spatial network analysis revealed that 87% of complaints had the same county of residence and county of presumed exposure. Frequency of complaints was negatively associated with linear distance between place of residence and place of exposure at the zip code level. Counties located in North and Central Florida, as well as some coastal areas in South Florida, had higher incidence rates of complaints. Those counties tend to have a large population density, and some are popular vacation destinations. On average, 96 FBOs were reported in Florida annually, of which 60% were confirmed with successful identification of the causative agent. The 56% of the confirmed FBOs were triggered by a complaint. Throughout the years, 2.4 to 2.8 FBOs and 1.4 confirmed FBOs were identified per 100 complaints. Ciguatera toxin was the cause of 40% of all FBOs in Florida, and only 28% of outbreaks were detected through complaints. In contrast, complaints were the main source of identifying outbreaks of norovirus, nontyphoidal Salmonella enterica, and scombroid food poisoning, as well as rare outbreaks of Clostridium perfringens, Cryptosporidium spp., Shigella spp., and Vibrio vulnificus.

The finding of pure organic emitter materials is the need of the hour for the mass production of cost-effective and metal-free fluorescent organic light-emitting diodes (FOLEDs). In this paper, we ...report a new series of perylene tetraesters (PTEs) that exhibit the room temperature columnar (Col) mesophase and can act as efficient fluorescent emitter materials in OLEDs. The molecular design involves the attachment of triazole moieties with the PTE discotic core
via
click chemistry. Triazole groups were chosen as they can improve the electron transport as well as tune the luminescence behavior of discogens. All the PTE derivatives

exhibited ordered columnar rectangular (Col

3a
as a sole emitter and in the dispersed form at 1, 5 and 8 wt% with the CBP host and at 5 wt% in the SimCP2 host. A significantly high value of the external quantum efficiency (EQE) of 6.5% is obtained in doped devices with the CBP host at 5 wt% dopant (
3a
) concentration with CIE coordinates of (0.37, 0.53) corresponding to green color. The obtained high EQE value will certainly offer an important step forward to expand the application of smart DLC materials in OLEDs.

In the past 60 years, India-China relations have oscillated between friendship, hostility and indifference. In recent times, both countries have started competing for global economic gains and ...political status. In light of these events, the objective of this article is to analyze various strategies used by China against India, and India's policy response to these strategies. The article evaluates the process of foreign policy decision making in India, and traces the historical evolution of India's foreign policy towards China. It then deconstructs China's foreign policy towards India, and provides the rationale behind its strategies. The article suggests that after initial engagement with India on the question of boundary disputes, Chinese foreign policy has undergone a dramatic shift since 2007. It specifically evaluates the twin Chinese tactics of military incursions and denial of legitimacy to the Indian territories of Arunachal Pradesh and Ladakh. Based on an analysis of China's previous boundary disputes resolution record with neighbors, these tactics are identified as an extension of China's new strategy for resolving such disputes. The article concludes by suggesting various policy options available to India to counter China's new strategy on the Sino-Indian border.

Transforming triplet excitons into singlet excitons is a topic of great interest to material scientists in order to surpass the exciton utilization efficiency (EUE) limit of 25% in ...electro-fluorescent devices. Towards this goal, the donor-acceptor strategy of molecular design has been proven to be an effective approach to obtain high electroluminescence (EL) efficiency. In this context, herein, we report two benzothiadiazole (BTD)-based donor-acceptor π-conjugated fluorescent molecules,
1
and
2
, which exhibited an external quantum efficiency (EQE) as high as 7.0% and 8.1%, respectively, in solution-processed doped green OLED devices. The observed high photoluminescence (PL) quantum yield of 81% for
1
and 85% for
2
corroborate the high EUE values of 43% and 48%, respectively, exceeding the traditional limit (25%), hence suggest the utilization of triplet excitons. The reported emitters combine two parameters,
i.e.
high PL efficiency and high EUE, which are of key importance to harvest maximum EL in OLED devices. Based on the photophysical (solvatochromic experiment) and quantum chemical calculations, the impacts of the D-π-A-π-D molecular design on the regulation of the locally excited and charge transfer components were revealed, which explained the observed high EQE (>5%) and EUE (>25%) values for the BTD-based emitters. The development of emitters with a hybrid local and charge transfer state in combination with the 'hot exciton' mechanism is an important strategy to produce highly efficient fluorescent-emitter materials. Besides the impressive EL properties of the emitters, the studied compound
