Reducing waste management challenges: Empirical assessment of waste sorting intention among corporate employees in Ghana

Waste sorting is seen as an effective and efficient step in annihilating the challenges of solid waste generation, promoting a circular economy, public health, and environmental sustainability. For total public acceptance and participation, it is crucial to understand what motivates and compels consumers to separate waste. Consequently, this study investigates corporate employees’ intention to sort waste in Ghana. The study augmented the theory of reasoned action with convenience, environmental consciousness, hedonic motivations, and awareness of benefits. 401 valid survey responses were statistically assessed using structural equation modeling. Results showed that the conceptual framework accounted for 65.4% of the variance. Attitude, subjective norm, environmental consciousness, awareness of benefits, convenience, and hedonic motivations were positive and significant toward waste sorting intention. Awareness of benefits influenced attitude but not convenience. Also, subjective norms positively and significantly influenced environmental consciousness and hedonic motivation. An ANOVA analysis confirmed the effect of gender, age and education on the inclination to sort waste. Hospitality and Educational sector employees had a higher inclination and intention to sort waste. The study advances literature and understanding on waste sorting among corporate employees and suggests practical solutions for ensuring total embrace and participation in sorting waste.     

Product specific values and personal values together better explains green purchase

Consumers not only buy green products to fulfil their environmental values but also seek product specific benefits from their green purchase. However, research predicting green purchases based on value-attitude integrated theoretical framework significantly overlooks an integrated approach of both personal values and product-specific values in determining green purchase intention. Employing a two-study (qualitative followed by quantitative) mixed method approach, current research fills this gap. Employing phenomenology, in-depth interviews in study-1 identified pre-dominant personal and product-specific values affecting green purchase. Employing theory of planned behaviour (TPB) and stimulus-organism-research (SOR) framework, study-2 proposed a model combining these identified values and empirically validated the model by collecting 401 online survey responses analysed through PLS-SEM. The findings from this study demonstrate that consumers green purchase attitudes and subsequent intentions are predominantly influenced by two personal values: altruism and biosphere; and two product-specific values: product quality and uniqueness. These results provide insights to organizations to craft their green marketing strategies by combining both personal and product specific values. This study extends the green consumption literature within an extended TPB plus SOR ambit.     

图式理论与英语听力教学

在听力教学过程中,学生不仅需要储备语言知识,还应储备文化背景知识,在大脑中建立大量图式.如果听者具备与听力材料相关的背景知识,听力理解的难度就会减小.因此,在教学过程中,教师应当注重引导学生积极扩大图式、充分利用图式,从而确实提高学生听力理解能力.     

平台到底是什么——基于分工与协调视角

以技术管理、战略管理、产业组织和生态系统为代表的研究视角,对平台本质的限制性理解直接导致学术界对平台到底是什么存在异议,将平台本质限制性理解为特定情境的平台功能是导致上述问题的根本原因。突破现有研究视角局限,引入分工与协调视角,对平台本质特征进行阐释是解决这个问题最好方案。在梳理平台本质特征的基础上,认为平台是一个以共享界面和接口为黏合剂的互补性自治主体进行分工与协调的元组织。通过解决平台本质研究中存在的争议与问题,揭示平台到底是什么,进而深化对平台的理解及在现实中的应用。

The impacts of country characteristics upon the value of information technology as measured by productive efficiency

Based on the theory of production, this paper investigates information technology (IT) contribution at a country level by linking it to the complementarity/substitutability phenomena created by the joint presence of IT and the five selected national characteristics. It negates the relationship between IT value and productivity based on a comprehensive panel data set from 25 countries over the period 1997-2006, when the individual analytical method is applied and productive efficiency is used as the performance criterion. The IT productivity paradox is re-examined under the one-equation stochastic frontier production model, while the influence of the five national characteristics is tested under the two-equation stochastic frontier production model. The findings include the following: (i) The IT productivity paradox occurs in not only middle-income (developing) countries but also high-income (developed) countries. (ii) Eastern European countries gain more productive efficiency than the G7 countries when IT is considered as a production factor. (iii) Different national characteristics have impacts on a country's output and productive efficiency. (iv) The chosen national characteristics present both complementarity and substitutability phenomena in association with IT investment, however, the joint presence of national savings and IT creates the substitutability phenomenon across different frontiers. (v) In linking cross-country differences in the IT investments to stages of economic development, our complimentary qualitative analysis tends to conclude that the investments in IT in the advanced developed countries (e.g., G7) and some of the newly developed or emerging economies are likely needed to keep the pace with other competitors and maintain their status of economic development; and the IT investments in the Eastern European countries are necessary to reach the competitive level as well as to raise their economic-development level. (vi) An important policy implication is that policy makers must carefully utilize national characteristics while formulating IT investment strategies.
