Organic food consumption: The relevance of the health attribute
2020
During the last decades, organic food products have become the main sustainable alternative to conventional food consumption. Among the several organic food attributes that consumers recognize in organic food, healthiness has been reported as the primary motivation to buy products certified as organic. The objective of the current study is to assess the relative weight of the health attribute among other recognized organic food attributes. To achieve this aim, a multiple price list (MPL) methodology is adopted to elicit consumers&rsquo
Sustainable Food Consumption Practices: Insights into Consumers’ Experiences
2021
In recent years, the increasing consumer concern towards food safety, environmental sustainability and social justice issues have stimulated new consumption practices more oriented towards social, economic, and environmental sustainability [1–3]. This includes the growing consumers’ preference for organic food, local food, and other sustainable food and beverage consumption (Contribution 1) [ 4], as well as the spread of alternative distribution chains, which emphasise the importance of local food productions [ 5 ], the short-distance transportation of food, and the direct relationship between consumers and producers, although, as Kwil and colleagues (Contribution 2) highlighted in this Spe…
Context as a Provider of Key Resources for Succession: A Case Study of Sustainable Family Firms
2019
[EN] Although succession is the single most important issue in family-owned businesses (FOBs), there is scarce comprehensive and integrative analysis of the context (i.e., the social, organizational, and normative setting) where succession events occur. Research usually focuses on the success or failure of succession processes, instead of the risks faced by FOBs during succession. The succession process takes time and multiple actors are involved. Therefore, succession is influenced by uncertainty and unforeseen events. This study addresses the aforementioned gap in the literature by investigating how context can reduce the risk of failure in succession. Based on organizational change theor…
Elektroutlenianie przepracowanego oleju 15W-40
2017
W pracy przedstawiono badania nad możliwością wykorzystania odpadowego oleju silnikowego 15W-40 do bezpośredniego pozyskiwania energii elektrycznej. Pomiary obejmowały elektroutlenianie emulsji odpadowego (zużytego) oleju silnikowego 15W-40 na gładkiej elektrodzie platynowej w kwasowym elektrolicie (H2SO4). Do wytworzenia emulsji wykorzystano detergent Syntanol DS-10. Pomiary przeprowadzono w temperaturze 293-333K. Maksymalna uzyskana gęstość prądu wyniosła 19 mA/cm2 (dla temp. 333K). Badania wykazały możliwość bezpośredniego wytwarzania prądu elektrycznego z odpadowego oleju silnikowego 15W40, a więc możliwość zasilania nim ogniw paliwowych.
Bezpośrednie wytwarzanie energii elektrycznej z oleju napędowego
2016
Ze względu na stale wzrastające zapotrzebowanie na energię elektryczną poszukiwane są coraz to nowsze rozwiązania, pozwalające na sprostanie temu wyzwaniu. W ostatnich latach oprócz tradycyjnych metod wytwarzania energii coraz dynamiczniej rozwija się energetyka niekonwencjonalna. Przykładem takiego rozwiązania jest stosowanie ogniw paliwowych, głównie ze względu na ich wysoką sprawność. Ogniwa te przetwarzają energię chemiczną bezpośrednio na energię elektryczną, z pominięciem procesu spalania paliwa. Najczęściej zasilane są wodorem, jednak problemy z jego przechowywaniem wymuszają poszukiwanie innych paliw. Ponadto ogniwa paliwowe mogą stanowić dodatkowe/zapasowe źródło energii elektryczn…

Effects of Entrepreneurial Orientation and Passion for Work on Performance Variables in Sports Clubs
2021
Entrepreneurial orientation and passion for work have been widely studied due to their effects on the behaviour and attitude of management teams in the short- and long-term. However, despite the influences of these variables on the sustainability and survival of an entity, there is a gap when considering the effects of these two performance variables in sports organisations. Therefore, the main objectives of this study were to understand the influences of entrepreneurial orientation and passion for work on service quality and sporting performance. To this end, 199 Spanish non-profit sports clubs were analysed using instruments with good psychometric properties. Data analysis was carried out…
Rational Herding in Reward-Based Crowdfunding: An MTurk Experiment.
2020
Crowdfunding is gaining popularity as a way of financing social sustainable initiatives. We performed a controlled economic experiment in MTurk by simulating a crowdfunding platform and developed a theoretical model that rationalizes herding behavior. The experiment was designed to test and quantify the causal effects of revealing specific information to prospective backers: (i) the number of early contributors already financing the project and (ii) positive opinions of other backers versus those of experts. The results show that early contributions to the campaign and positive opinions of peers act as a reinforcing signal to potential backers and affect backers&rsquo
Coping Strategies against peer victimization: differences according to gender, grade, victimization status and perceived classroom social climate
2021
The Sustainable Development Goals (SDGs) include “Good Health and Well-being” (SDG3) and “Quality Education” (SDG4). Nevertheless, many students cannot achieve these goals if they suffer peer victimization at their schools, and intervention programs to reduce it are necessary. These programs should consider the possible differences in the coping strategies preferred by students according to some personal (e.g., gender, grade, victimization status) and contextual (e.g., perceived classroom social climate) factors to be more effective. Therefore, the objective of this study was to analyze the possible differences in the coping strategies preferred by students (ask a friend for help, ask a tea…
Adoption of social media marketing for sustainable business growth of SMEs in emerging economies: The moderating role of leadership support
2021
Social media marketing (SMM) plays an important role in business communication, marketing, operations, and other activities. There is a growing interest among researchers, academicians, and practitioners to understand the role of SMM in business sustainability in small and medium enterprises (SMEs) in an emerging economy, like India. Few studies have attempted to understand this role. Thus, the aim of this study is to examine the impact of adopting social media marketing for sustainable business growth of SMEs in an emerging economy. The study also investigates the moderating role of SME leadership support on the relationship between SMM usage and sustainable business growth of SMEs. After …
