This paper aims to propose and test a model facilitating assessment of tactical planning maturity in supply chains of manufacturing companies. The author proposes a model called Tactical Planning Maturity Model (TPMM). The model is created based on literature research, participant observations and data gathering conducted in two companies. The proposed framework combines both knowledge from supply chain integration and steps necessary to reach proficiency in sales and operation planning. The second step consists of choosing a case study method to verify model adequacy in two companies operating in central Poland. The findings illustrate the TPMM as a ready-to-use tool where the line to supply chain maturity is clearly drafted and results could be compared between production companies. This paper strengthens the link between practitioner and academic literature by providing empirical evidence of the benefits of tactical planning maturity model usage as well as its impact on further development of supply chains. This paper studied merely two companies and is not intended to be representative of outcomes for all companies looking to understand the complexity and maturity of their supply chains. Furthermore, the analyzed companies only reached level four in the maturity model; levels five and six were not observed. Further quantitative studies are required for testing the accuracy of the proposed model and potentially, qualitative studies could be undertaken in order to understand factors enabling the increase in maturity of tactical planning in the supply chains of manufacturing companies.
本文旨在提出并检验一个便于评估制造企业供应链战术规划成熟度的模型。本文提出了战术规划成熟度模型(TPMM)。该模型是基于文献研究、参与者观察和两家公司的数据收集而创建的。所提出的框架结合了来自供应链集成的知识和达到销售和运营计划熟练程度所需的步骤。第二步包括选择一种案例研究方法来验证在波兰中部经营的两家公司的模型充分性。研究结果表明,TPMM是一个现成的工具,其中供应链成熟度线是明确起草的,结果可以在生产公司之间进行比较。本文通过提供战术规划成熟度模型使用的好处以及其对供应链进一步发展的影响的经验证据,加强了实践者和学术文献之间的联系。本文仅研究了两家公司,并不打算代表所有希望了解其供应链复杂性和成熟度的公司的结果。此外,所分析的公司在成熟度模型中仅达到第四级;没有观察到第五级和第六级。需要进一步的定量研究来测试所提出模型的准确性,并可能进行定性研究,以了解使制造公司供应链中战术规划成熟度提高的因素。

A TYPOLOGY OF MALE CONSUMERS ON THE MEN’S ELEGANT FASHION MARKET: CASE STUDY OF POLAND 男性优雅时尚市场中男性消费者的类型学:波兰个案研究
Pub Date : 2021-12-21 DOI: 10.22630/aspe.2021.20.2.16
G. Maciejewski, Dawid Lesznik
The authors of the presented article conducted primary research among contemporary gallants, aiming to identify consumer types within the niche of elegant men’s clothing, including possible dandies. In the conducted study, online surveys were posted on internet forums and thematic groups focused on Polish male smart dressers. As many as 30% of respondents considered themselves as dandies, and three types of customers were distinguished: exacting sartorialists, low-budget gallants and phonies. The difference between the first two is mainly due to disparities in purchasing budgets. Phonies, on the other hand, appear to be superficial in purchase decisions, perhaps gaining interest in an elegant style only as a temporary whim. The results will prove useful for brands in the men’s elegance segment, broadly highlighting the in-depth characteristics of different customer groups. Moreover, contrary to the subject literature, the research shows that dandyism is still a lively trend.
这篇文章的作者对当代绅士进行了初步研究,旨在确定优雅男士服装细分市场的消费者类型,包括可能的花花公子。在进行的研究中,在线调查被张贴在互联网论坛和主题小组上,重点关注波兰男性的聪明着装。多达30%的受访者认为自己是花花公子,他们区分了三种类型的顾客:严格的裁缝师、低预算的献殷勤者和骗子。前两者之间的差异主要是由于采购预算的差异。另一方面,冒牌货在购买决定上显得肤浅,也许对优雅的风格产生兴趣只是一时的心血来潮。研究结果将对男士优雅细分市场的品牌有用,广泛地突出不同客户群体的深度特征。此外,与主题文献相反,研究表明,花花公子主义仍然是一种活跃的趋势。

Ewa Frąckiewicz
The aim of the article is to present the legitimacy and conditions of research on seniors and its challenges in the context of further development of the information society (IS). The conducted considerations lead to the conclusion that research of this nature is limited by the lack of unambiguity in the concept of elderly persons and the information society. Nevertheless, it has been argued that studies of older people as members of the IS are fully justified by the importance of this group in society as a whole. Whereas analysis conducted on those aged 60 years and over, or 65 years and over, is insufficient. Older people should be analyzed in smaller age ranges and the analyses require both quantitative and qualitative approaches. Qualitative approaches improve our understanding of the reasons that new technologies are used or rejected, which can help to achieve one of the goals of IS development – to increase the quality of life for seniors in the future.
本文的目的是在信息社会(is)进一步发展的背景下,提出老年人研究的合法性和条件及其挑战。所进行的考虑导致的结论是,这种性质的研究受到老年人和信息社会概念缺乏模糊性的限制。然而,有人认为,将老年人作为IS成员的研究是完全合理的,因为这一群体在整个社会中的重要性。然而,对60岁及以上或65岁及以上的人进行的分析是不够的。老年人应该在较小的年龄范围内进行分析,分析需要定量和定性的方法。定性方法提高了我们对新技术被使用或被拒绝的原因的理解,这有助于实现信息系统发展的目标之一——提高未来老年人的生活质量。

THE MULTIPLE REGRESSION MODEL WITH DICHOTOMOUS VARIABLES IN ANALYSIS OF MULTI-SECTIONAL DEMAND FOR CONNECTIVITY SERVICES – APPROACH BASED ON PER SECOND BILLING 多区段连接服务需求分析中的二元变量多元回归模型——基于每秒计费的方法
Pub Date : 2021-12-21 DOI: 10.22630/aspe.2021.20.2.15

The article presents the results of comparative research of the effectiveness of two types of models in terms of approximation and short-term forecasting of the multi-sectional demand for connectivity services. The presented results of the analyses are related to the selection of an appropriate forecasting method as an element of the Prediction System dedicated to telecommunications operators. The first tested model was a multiple regression model with dichotomous explanatory variables. The second model was a multiple regression model with dichotomous explanatory variables and autoregression. In both models, the dependent variable was the hourly counted seconds of outgoing calls within the network of the selected operator. Telephone calls were analysed in terms of such classification factors as: type of day, category of call, group of subscribers. Taking into account all levels of classification factors of the explanatory variable, 35 dichotomous explanatory variables were specified. The defined set of dichotomous explanatory variables was used in the estimation process of both compared regression models. However, in the second model, first-order autoregression was additionally applied. The second model (multiple regression model with dichotomous explanatory variables with first-order autoregression) was found to have higher approximation and predictive capabilities than the first model (multiple regression model with dichotomous explanatory variables without autoregression).
本文介绍了两种模型在连接服务多断面需求近似和短期预测方面的有效性对比研究结果。所提出的分析结果与选择适当的预测方法有关,作为电信运营商专用的预测系统的一个要素。第一个被检验的模型是具有二分类解释变量的多元回归模型。第二个模型是具有二分类解释变量和自回归的多元回归模型。在这两个模型中,因变量都是在所选运营商的网络中每小时计算的呼出电话秒数。电话是根据以下分类因素进行分析的:日期类型、电话类别、用户群体。考虑到解释变量的各级分类因子,确定了35个二分类解释变量。在两种比较回归模型的估计过程中都使用了定义好的二分类解释变量集。然而,在第二个模型中,增加了一阶自回归。发现第二种模型(二分类解释变量加一阶自回归的多元回归模型)比第一种模型(不加自回归的二分类解释变量的多元回归模型)具有更高的近似和预测能力。

Pub Date : 2021-12-21 DOI: 10.22630/aspe.2021.20.2.17
A. Sagan
The paper presents the graphical approach to decomposition of APC effect in cohort studies (mainly applied to demographic phenomena) using multilevel or accelerated longitudinal design. The aim of the paper is to present and visualize the pure age, period and cohort effects based on simulated data with an increment of five for each successive age, period and cohort variation. In cohort analysis on real data all of the effects are usually interrelated. The analysis shows basic patterns of two-variate APC decomposition (age within period, age within cohort, cohort within period, period within age, cohort within age, period within cohort) and reveals the trajectory of curves for each of the pure effects. The APC plots are developed using apc library of R package.
本文提出了用多水平或加速纵向设计来分解队列研究(主要应用于人口现象)中APC效应的图形方法。本文的目的是在模拟数据的基础上呈现和可视化纯粹的年龄、时期和队列效应,每个连续的年龄、时期和队列变化增量为5。在对真实数据的队列分析中,所有的影响通常是相互关联的。分析显示了两变量APC分解的基本模式(期内年龄、期内年龄、期内队列、期内年龄、期内队列、期内队列),并揭示了每种纯效应的曲线轨迹。使用R包中的APC库开发APC图。

The main goal of this paper is to evaluate the health status of Poles in the context of their dietary patterns. Results of a desk research study on dietary habits of persons working during the coronavirus pandemic and attitudes of Poles towards meal delivery services provided to the authors by external research institutions were utilized for the purpose of the article. In the framework of practical scientific cooperation, the following reports containing results of research on dietary patterns of people working during the pandemic have been made available for the purpose of this study: “Healthy, speedy or conveniently?” and “Healthy eating”. The results were used with retain of copyright and ethical principles. Data analysis led to the conclusion that people have tended to pay more attention to the food intake as well as spend more time on self-preparation of meals during the pandemic. Based on analysis of the study results, a thesis was formulated that during a pandemic, we pay more attention to what we eat, and we also spend more time preparing meals on our own. Assuming that the population of Poland in 2020 was 38,265 thousand people, it could be stated in the light of the study results that almost 650 thousand Poles were on a well-balanced diet adapted to individual consumer needs.
本文的主要目的是评估波兰人在其饮食模式背景下的健康状况。一项关于冠状病毒大流行期间工作人员的饮食习惯和波兰人对外部研究机构向作者提供的送餐服务的态度的桌上研究结果被用于本文的目的。在实际科学合作的框架内,为本研究的目的提供了以下报告,其中载有大流行期间工作人员饮食模式的研究结果:"健康、快速还是方便?和“健康饮食”。研究结果的使用保留了版权和道德原则。数据分析得出的结论是,在大流行期间,人们倾向于更加关注食物的摄入量,并花更多的时间自行准备食物。在分析研究结果的基础上,提出了一个论点,即在大流行期间,我们更关注自己吃的东西,也花更多的时间自己准备饭菜。假设波兰2020年的人口为38265万人,根据研究结果可以得出,近65万波兰人的饮食均衡,适应个人消费需求。

THE OCCURRENCE OF MISSING DATA IN SURVEYS 调查中数据缺失的情况
Pub Date : 2021-12-21 DOI: 10.22630/aspe.2021.20.2.19
Wioleta Zdebska
The purpose of this article is to discuss issues related to the analysis of missing data. Why do missing data occur in a data set? What percentage of the collected data constitutes missing data? What is the nature of missing data that emerges during data collection? The above questions are extremely important in assessing conducted surveys or in evaluating the quality of the collected data. A lack of reflection on the aspects mentioned above may lead to false conclusions and recommendations. This article presents not only an overview of the literature regarding missing data, but also shows how in a practical way an analysis of the randomness of missing data can be performed. The analysis presented in the article is based on data collected as part of the Polish General Social Survey carried out in 2008. The main recommendation of the author is to conduct an analysis of the randomness of missing data before analyzing the collected data.
本文的目的是讨论与缺失数据分析相关的问题。为什么数据集中会出现缺失数据?收集的数据中有多少百分比构成缺失数据?在数据收集过程中出现的缺失数据的本质是什么?上述问题在评估所进行的调查或评估所收集数据的质量时极为重要。对上述各方面缺乏反思可能导致错误的结论和建议。本文不仅概述了关于缺失数据的文献,而且还展示了如何以实际的方式对缺失数据的随机性进行分析。文章中提出的分析是基于2008年波兰综合社会调查收集的数据。作者的主要建议是在分析收集到的数据之前,先对缺失数据的随机性进行分析。

Pub Date : 2021-12-20 DOI: 10.22630/aspe.2021.20.2.11
Irena Boboli, Etleva Muça (Dashi)
Tourism expenditures are an important indicator for measuring the impact of tourism on a destination. Information taken from the micro data of tourism expenditures, together with other socio-demographic characteristics of visitors, provides important data on the tourist demand for a destination. Visitor costs in combination with other variables can be used to profile the demand for tourist goods and services in the destination area. In this paper, the daily expenses of visitors in the Gjirokastra district of Albania are analysed. The Gjirokastra district is one of the more preferred regions and attracts a considerable number of domestic and foreign visitors, because it offers a diversity tourist attractions and services. For the purposes of this study, a survey of 200 visitors was conducted. The survey results were analysed with descriptive statistics via a cluster analysis. The survey provides detailed data on the daily expenses of visitors, divided into six main categories of a typical travel budget. Through the use of data mining cluster analysis, we identified and analysed the tourists’ daily expenses based on the purpose of their visit to the area of Gjirokaster.
旅游支出是衡量旅游对目的地影响的重要指标。从旅游支出的微观数据中获得的信息,连同游客的其他社会人口特征,提供了关于旅游目的地需求的重要数据。游客成本与其他变量相结合,可以用来描述目的地地区对旅游商品和服务的需求。本文对阿尔巴尼亚吉罗卡斯特地区游客的日常开支进行了分析。吉罗卡斯特区是一个更受欢迎的地区,吸引了相当多的国内外游客,因为它提供了多样化的旅游景点和服务。为了进行这项研究,我们对200名游客进行了调查。通过聚类分析对调查结果进行描述性统计分析。该调查提供了游客日常开支的详细数据,将典型的旅行预算分为六大类。利用数据挖掘聚类分析方法,对游客在吉洛卡斯特地区的旅游目的进行了日常消费识别和分析。

Market changes in consumer behavior can take a desirable, positive form and be accepted by other market participants, or they can be contrary to accepted social norms. According to Fullerton and Punj [1998] such behavior is the great paradox of modern consumer culture. Dysfunctional consumer behavior has become an inherent part of modern consumer behavior. The purpose of this paper is to review the results of research on dysfunctional consumer behavior based on selected scientific publications. The presentation of research topics and results will be made in two separate parts. The first part concerns the dysfunctional behaviors of customers, i.e. the way they are presented in the literature and the factors determining such behavior. The second part includes a review of research results concerning the broadly understood consequences of dysfunctional customer behavior.
消费者行为的市场变化可以采取可取的、积极的形式,并为其他市场参与者所接受,也可以与公认的社会规范相反。Fullerton和Punj[1998]认为,这种行为是现代消费文化的一大悖论。失调的消费者行为已经成为现代消费者行为的固有组成部分。本文的目的是回顾在科学出版物的基础上对功能失调消费者行为的研究结果。研究课题和结果的展示将分两部分进行。第一部分关注客户的功能失调行为,即他们在文献中呈现的方式以及决定这种行为的因素。第二部分包括对广泛理解的功能失调客户行为后果的研究结果的回顾。

The main purpose of the article was to assess Poland’s income situation in agriculture after the country acceded to the European Union. The analysis included, among others, changes in agricultural income per full-time employee and a comparison of household income of farmers and other professional groups. The sources of the materials were data from the Eurostat and CSO databases. The research period covered the years 2005–2018. The real income of the agricultural population in the analyzed period showed an upward trend but was still lower not only than the national average, but also the income of households of employees. Financial resources transferred from direct payments and structural funds under the Common Agricultural Policy had a significant impact on the improvement of the income situation of farmers.
这篇文章的主要目的是评估波兰加入欧盟后的农业收入状况。除其他外,该分析包括每位全职雇员农业收入的变化,以及农民和其他专业群体家庭收入的比较。材料的来源是来自欧盟统计局和公民社会组织数据库的数据。研究期间为2005-2018年。分析期内农业人口的实际收入呈上升趋势,但仍低于全国平均水平,也低于职工家庭收入。根据共同农业政策从直接支付和结构基金转移的财政资源对改善农民的收入状况产生了重大影响。
