The simulated scenarios can be used to compute risk premiums per risk class in the portfolio. These can then be used to adjust the policy premiums by accounting for storm risk.

A complete model to analyse and characterise future losses of the property portfolio of an insurance company due to hurricanes is proposed. The model is calibrated by using the loss data of the Fidelidade insurance company property portfolio resulting from Hurricane Leslie, which hit the centre of continental Portugal in October, 2018.

Several scenarios are simulated and risk maps are constructed. The risk map of the company depends on its portfolio, especially its exposure, and provides a Hurricane risk management tool for the insurance company.

A statistical model is considered, in which weather data is not required. The authors reconstruct the behaviour of storms through the registered claims and respective losses.

In the performance measurement and management research field, the applicability of performance measurement systems (PMS) in nonprofit organizations (NPOs) and public administration has been considered a challenge. The diversity of these organizations makes it difficult to define proper terminology and organizational characteristics. PMS evolution has not yet been able to capture all performance dimensions of a public administration and, especially for NPO considering its dynamic and multiple goals. The purpose of this paper is to provide a conceptual framework that identifies and classifies the factors that influence the design of PMSs in NPOs and public administration.

The study was developed through a systematic literature review (SLR). A set of 29 papers were intensely studied, and the results provide a multi-disciplinary and holistic set of factors.

A set of ten factors that influence the design of PMSs in NPO and public administration were found. They were categorized into three groups: factor related to purpose, stakeholders and management.

The study synthesized the literature and provided a conceptual framework of the factors that influence the design of PMSs in NPO and public administration. No individual paper collected in the SLR shows a similar organization of the factors as the present paper. The set of factors indicates the importance of this study for NPO and public administration, and how complex a PMS in an NPO and public administration can become. The conceptual model presented can further assist practitioners in developing design process observing the role that the identified factors play.

This study aims to investigate the food choice motivations of rural households using a cross-sectional dataset of 510 households from northwest Vietnam interviewed in 2016.

A modified Food Choice Questionnaire (FCQ) is used to assess factors related to food choice and explore relationships between food choice factors, diet quality and various sociodemographic characteristics.

Results show four distinct food choice factors: “Natural and healthy,” “Familiarity,” “Balanced diet” and “Convenience.” Two distinct consumer clusters are identified: “Health-conscious” households and “Pragmatic” households. “Health-conscious” households rank “Balanced diet” and “Natural and healthy” highly, while “Pragmatic” households prioritize “Convenience” and “Familiarity.” “Health-conscious” households have significantly more diverse diets, are wealthier and have a greater geographic concentration in the high vegetable density per capita-high elevation areas (36%). Their main food preparers are more educated and about 13% have Kinh ethnicity.

Further research is warranted to explore the temporal dimension of parental food choice motivations given the changing agrifood system in Vietnam.

This study is one of the few studies that assess the food choice motivations among ethnic minority groups in a rural setting.

The research empirically investigates the firm-level impact of ISO 9000 certification on innovation propensity. The study aims to distinguish between manufacturing and service sectors and adopts different innovation definitions aimed at capturing the peculiarities of innovation in services and small firms.

Relying chiefly on Community Innovation Survey data for Luxembourg, the impact of certification on innovation probability is assessed using a logit model that controls for relevant firms characteristics and market features.

The innovation potential of services and small firms is understated when adopting innovation definitions restricted to technological aspects and more formalised innovation activities. ISO 9000 certification may promote innovation when adopting definitions that captures sectoral innovation specificities. In particular, certification increases innovation propensity in manufacturing when the focus is on technological innovation and formalised innovation expenditures. On the contrary, when non-technological aspects are included and allowance is made for wider innovation activities, the impact of certification on services tends to emerge. However, sharper statistical evidence for manufacturing indicates a more important role of certification for innovation success in this sector.

Case-study research could supplement the findings concerning the relative effectiveness of certification in services and manufacturing. The investigation would also benefit from extensions in the econometric analysis to address comparisons across samples and potential causality issues.

Findings are interesting to practitioners and registrars in order to identify the specific characteristics of firms for which certification provides higher innovative potential.

The study highlights the relevance of sectoral specificities and innovation definitions for the debate about the effect of ISO 9000 certification on innovation.

The purpose of this paper is to investigate health care consumers’ diabetes term usage patterns based on Yahoo!Answers social question and answers (Q&A) forum, identified characteristics and relationships among terms within three pairs of related categories identified from the Q&A log, and revealed users’ diabetes term usage patterns.

The Q&A analysis method allowed first-hand investigation of massive data from health care consumers. Visual term clustering analysis across categories was conducted using a multi-dimensional scaling (MDS) visualization method which provides an intuitive and interactive way to explore and discover term association patterns in a visual environment. Closely related categories were identified and corresponding visual term clustering analyses between categories (Sign & Symptom and Organ & Body Part; Diagnosis and Test; and Diagnosis and Medication) as well at the term level were analyzed.

The findings show that there are close relationships between terms in two related categories. Related terms were grouped and patterns were revealed. All the stress values of the MDS analyses fall below 0.10 and RSQ for each of the combined categories is over 0.90 which indicate the investigated terms were well clustered in the visual analyses.

The study provides a unique research methodology for similar consumer health research studies. The results of this study offer insight into consumer health term use behavior, and enrich existing thesauri and subject heading lists, enhance diabetes-related web sites or portals, and improve effectiveness of internal search engines.

The primary objective was to determine the prevalence of indicator microorganisms [Staphylococcus aureus, non-S. aureus staphylococci (NSAS), coliforms and aerobic bacteria] for contamination of chicken carcasses, carcass drip and rinse water from the informal chicken market in Gauteng, South Africa.

Chicken swabs, chicken drips and rinse waters were collected from 151 chickens from 47 random outlets. Pre-tested questionnaires were administered to capture the risk factors for bacterial contamination. Standard microbiological procedures were conducted for isolation and enumeration of target bacteria.

NSAS (64% and 41%) and S. aureus (12% and 31%) were prevalent on carcasses and in carcass drip respectively. Coliforms (62%) and aerobic bacteria (85%) were detected in rinse water. Significant risk factors for contamination of carcasses with NSAS, S. aureus and coliform organisms were: evisceration of chickens on the same location used for sale, cleaning of display counter with dirty clothes/wipes, holding of differently sourced chickens in the same cage prior to slaughter, not cleaning the display table/counter and hands at all, washing knives in rinse water, high turnover of daily slaughter and length of time to display chickens.

The limitations of this research were the limited geographical coverage and small sample size.

The isolation of these indicator microorganisms suggests the potential presence of other chicken-borne pathogens not tested for in the study.

The findings serve to inform policy on public health and street-vended food and can guide control on good sanitary practices.

This is the first comprehensive report on ready to eat chickens from the informal markets in Gauteng, South Africa.

Successful knowledge transfer (KT) between younger and older workers (YW and OW, respectively) is critical for organizational success, especially in light of the recent surge in employment volatility among the youngest and oldest segments of the workforce. Yet, practitioners and scholars alike continue to struggle with knowing how best to facilitate these exchanges. The qualitative study offers insight into this phenomenon by exploring how KT unfolds in YW/OW dyads.

The authors performed a reflexive thematic analysis of semistructured interviews with two samples of blue- and white-collar younger/older workers from the USA (N = 40), whereby the authors interpreted the “lived experiences” of these workers when engaged in interdependent tasks.

The analysis, informed by social exchange theory and exchange theories of aging, led to the development of the knowledge transfer process model in younger/older worker dyads (KT-YOD). The model illustrates that, through different combinations of competence and humility, KT success is experienced either directly (by workers weighing the perceived benefits versus costs of KT) and/or indirectly (through different bases of trust/distrust perceived within their dyads). Further, humility in dyads appears to be necessary for KT success, while competence was insufficient for realizing KT success, independently.

In exposing new inner workings of the KT process in YW/OW dyads, the study introduces the importance of humility and brings scholars and organizations a step closer toward realizing the benefits of age diversity in their workplaces.
