A unitary scheme which classifies certain subsystems, within production management, according to push and pull logics is proposed. The three subsystems described are: inventory management, manufacturing priority assignment and material picking and moving, and production planning. The classification proposed is a starting point for establishing application requirements. The characteristics of the production context, not the inherent logic, determine the choice of the most feasible techniques. Techniques with different logics can hence coexist in the same production system.

This paper contributes to the emerging literature on the adoption of environmental innovation, by investigating the so far unexplored role of governmental demand in stimulating 'greener' production choices. Specifically, the role of innovative public procurement in driving the adoption and diffusion of sustainable manufacturing technologies is analysed. Results, based on firm-level data in the 28 Member States of the European Union, Switzerland and the USA, are obtained through non-parametric matching techniques. Those outline the crucial role of innovative public procurement in the uptake of environmental innovations. This confirms the relevance of such policy instrument in allowing countries to achieve a decarbonised and sustainable growth path which is compatible with competitiveness goals.

imposes significant capacity management problems. Making decisions which
involve levels of customer service and resource untilization can be
aided by the application of the calculation methodology outlined, which
uses standard spreadsheet techniques and forecast queue analysis.
Presents a case example to clarify the links between service levels and
resource utilization which can aid management decisions regarding
timing, levels of stocks and sizing of facilities.

The purpose of this study is to examine the role of push and pull factors that have influenced China's outward foreign direct investment (COFDI) in the Belt and Road Initiative (BRI) countries. The sample of BRI countries is divided according to three geographical regions representing Europe, MENA, and Asia for better understanding of the main factors that influence the COFDI across the respective regions. This study supports Dunning's FDI theory in modeling the determinants of COFDI in BRI economies by focusing on the role of push and pull factors. This present study also extends and improves the existing research by considering the new factors, new methodology, and splitting the sample BRI economies. Thus, a static, dynamic panel and quantile regression technique was employed to model COFDI determinants for 50 BRI countries from 2005 to 2016. The main findings revealed that China's minimum wage policy, including the host countries' natural resources, labor cost, and institutional factors were the key determinants influencing COFDI. However, some determinants such as the host countries' gross domestic product, total patents, trade openness, and inflation rate did not significantly influence COFDI. By splitting the sample according to the respective regions, the results revealed that only the minimum wage policy significantly influenced COFDI in the European region. In comparison, natural resources, gross domestic product, and minimum wage policy were statistically significant for the MENA region. In the Asian region, minimum wage policy, government index, and trade openness were proven essential for COFDI. The policy implications from this study suggest that MNCs from China need to strategize their location for investment in BRI economies. In complement, the BRI recipient countries need to show their advantage and strength in attracting more FDI from China. BRI economies and China MNCs can also be leveraged through understanding how strong the push and pull factors are exerting on outward investment from China. ...

The Federal Government of Nigeria intensified the Formation of Cooperatives in the eighties as part of her economic reform and poverty alleviation programmes in almost all the states. Abia people's favourable disposition to adoption of cooperative system as a strategy for enhancing agricultural and rural development is evident from the great number of persons that are engaged in cooperative activities, especially in the rural communities of Abia State. Worrisome, however, is the high rate of membership turnover. This prompted an investigation with the aim of ascertaining factors responsible for fluidity of membership of these groups. A multi-stage, stratified sampling technique was adopted in selecting 25 cooperative societies and 150 cooperators covered in the study. Descriptive statistics such as percentages was used in data analysis. Participation in cooperative activities was found to have been influenced mainly by poverty (58.7%) among the people. Cooperative membership was also perceived as an avenue for socialization (25.40%) and savings mobilization (37.3%). The inability of these societies to satisfy members social, affiliative and biological needs and, consequently, enhance their well-being was found to be a disincentive to belonging to such groups. Given the relevance of these societies, it is recommended that, among other things, the activities of Abia State Economic Empowerment Development Strategies (ABSEEDS) be intensified to improve participation in cooperative societies in the State.

AbstractDesert locusts (Schistocerca gregaria) pose a significant threat to food security. However, they also serve as a nutrient‐rich delicacy in many African and Arabic communities where they are traditionally harvested for food and feed. Traditional harvesting methods are inefficient, laborious, and time‐consuming; hence, there is a need to explore more convenient and efficient techniques. This study assessed preferential selection and feeding behavior of desert locusts to identify trap plants that could attract and aggregate them for easy harvesting. Four trap plants (cowpea, finger millet, sorghum, and amaranth) and four repellent plants (neem, pencil cactus, garlic, and cayenne red pepper) were evaluated through multiple‐choice experiments. A randomized complete block design involving mature adult, immature adult, and hopper stages of desert locusts was used. Analysis of variance was used to determine the effects of repellent and trap plants on feeding preferences of desert locusts. Mean differences between treatments at p < 0.05 were separated using post hoc Tukey's honestly significant difference. Cowpea as the most preferred trap plant attracted 62.7%, 70.7%, and 76.9% of mature adult, immature adult, and hopper locust stages, respectively. Neem exhibited the most potent repellent effect and attracted no desert locusts for feeding. Neem repelled locusts, thereby reducing infestation and damage of cowpea as a pull plant when both plants were grown in the same pot in a "push–pull" system. The push–pull attracted 3.7%, 24.3%, and 7.8% of mature adult, immature adult, and hopper locust stages, respectively. However, cowpea attracted large numbers of locusts (96.3% mature adults, 75.7% immature adults, and 92.2% hoppers) when grown separately from neem. These findings provide valuable insights on the potential of exploiting traps and repellents to enhance aggregation and harvesting of desert locusts as food and feed.

Jung Yeol Choi,1 Young Keun Han2,3 1Department of Ophthalmology, Jeju National University Hospital, Jeju, South Korea; 2Department of Ophthalmology, Seoul Metropolitan Government-Seoul National University Boramae Medical Center, Seoul, South Korea; 3Department of Ophthalmology, Seoul National University College of Medicine, Seoul, South Korea Abstract: We describe a modified scleral fixation method to facilitate the good centration and adequate tension of sutures at both ends with addition of an internal fixation knot that reduces decentering of the IOL in a patient with postsurgical aphakia. Using an ab externo suture technique to fixate the haptics to the scleral wall, an additional loop knot is tied 1 mm next to the fixation knot at the haptic. In the technique, an internalized suture and an additional suture knot is tied while holding it close to the fixation knot at the haptic using a needle holder or McPherson forceps. The externalized sutures are secured by taking a bite of transclera and tying the suture to itself. This technique is simple and easy, and adds an internal check valve to prevent excessive pull and decentering of the intraocular lens at one side. The internal check valve also serves as a criterion for the point of fixation at each end. Keywords: modified technique, intraocular lens scleral fixation, postsurgical aphakia

The Kaliningrad region's attractiveness to migrants results in increasing external (interna­tional) and interregional migration. The interregional flow is a major contributor, accounting for approximately 60 per cent of the net migration gain. However, the age composition and pro­fessional qualification of migrants from other regions of Russia do not fully agree with the specifics of the region's labour market and its strategic socio-­economic development priori­ties. This lends urgency to a selective regional migration policy aimed at prospective internal migrants. Yet, the picture of pull, push and hindering factors remains incomplete, being limit­ed to generally accepted drivers such as coastal location and proximity to EU countries. This article aims at a detailed analysis of reasons to migrate to the region, an assessment of the re­strictions and difficulties faced by relocatees and migrants' satisfaction with the new place of residence. Method­ologically, the study uses a mixed strategy: formal data collection methods are combined with respondent selection techniques peculiar to qualitative or expert methods. The authors draw on the results of an exploratory survey conducted in December 2021 with a view to analyse migrants' perception of the Kaliningrad region before and after their arrival and assess how their ideas change. The survey applied mixed research methods: respondents were recruited via social media and relocatee groups. The data analysis reveals a gap between migrant expectations and reality, identifying the causes of inconsistency between the incoming migration flow and the region's development objectives and labour market needs. Based on the findings, the authors provide recommendations for a migration policy based on an accurate picture of the region and aimed at attracting the required workforce, as well as at migrants' adaptation and support at the new place of residence.

This article analyzes Push, Pass, Pull Political Marketing Adnan Purichta Ichsan-Abdul Rauf Mallagani At the Election of Regional Heads in Gowa Regency 2015. This study uses qualitative research methodology, with data obtained through interviews, literature studies and documentation. The analysis technique uses data reduction, data presentation, and conclusion drawing. The results of the study show that 1). The results of the electability survey of JSI, LSI and IPI as well as the vision and mission that are used as selling political products can ultimately give influences to the formation of public opinion, so that voters solidify their choice of candidates who are marketed. This push-marketing strategy is carried out as a rational and emotional stimulant to voters. 2). The involvement of Ichsan's character in the political marketing pass strategy by Adnan's team was able to become the ideal influencer for rational voters and loyalists of Yasin Limpo's family in the 2015 Gowa Regency Election. 3) Strategy Pull Political Marketing whose expectations for forming Adnan's image is not optimal due to Ichsan's under the shadow. Even so, there are still efforts to form a positive political image. One of them is through branding on various media especially social media.Keywords: Push, Pass, Pull Political Marketing; Winning Strategy, Local Election

In the 1990s, demands for change in public organizations are
reaching new and unfamiliar levels. The continuing fiscal crisis and
widespread disenchantment with governing institutions suggest that
traditional change practices that gradually adapt public organizations
to their environment are losing credibility. Abrupt discontinuities such
as severe budget cuts or the wholesale reassignment of a mandate are
becoming more common. These discontinuous changes present public
managers with an extraordinary challenge to transform their
organizations. Managing such change requires different skills and
techniques and will be a conclusive test of leadership. Develops a
conceptual framework to help managers to think about managing strategic
shocks that have no precedent.
