    Supply chain
    Opis:
    A general supply chain functions as a closed cluster and consists of at least three companies: supplier, producer and buyer. In an optimal case the companies within a supply chain are well integrated, partnership rests on trust which results in common strategic decisions. Business practices show that there is a stronger company within the chain that uses its power position to influence network development. The objective of the research is to measure how and what kind of power position is needed to influence the supply chain. The hypothesis states, that power and network development are opposite effects in a supply chain. Statistical examination of data gained from 221 companies state that the company with power position has advantages if the supply chain extends. SPSS analysis proves that the hypothesis is false and opens a new direction of research. Companies within the supply chain have to cope with power structures while cooperating with each other. They tend to look for solutions to ease dependency. Using or misusing power has several factors; mainly they are inherited from the strongest link of the supply chain. This is usually a problem but the results of the statistical analysis show that still a win-win situation is needed for the companies in order to deepen the cooperation. To conclude this research the data shows that the goal is to be more competitive as a chain, not just as a company.

    Opis:
    Elements of geodiversity evaluated for scientific value should be protected, conserved and promoted as potentially important for geotourism. The Divjakë-Karavasta National Park is a large natural area that comprises six geosites along the Adriatic coastline of Albania. Geosites are elements of the geosphere that should be preserved for geoeducation of the present and future generations, in view of the fact that they yield significant data on Earth’s history. By means of the Geosite Assessment Method (GAM) and the SPSS program (version 20), we have analysed the geotouristic values of the Divjakë-Karavasta geosites and interpreted the importance of each subindicator. A correlation analysis, performed through SPSS and Pearson’s correlation coefficient as a test statistics, has been carried out as well. The Pearson’s correlation coefficient reflects the strong relationship between the scientific/educational values (i.e., representativeness and scientific knowledge) and touristic values (promotion, number of visitors, interpretative panels, hostelry services, restaurant services, touristic infrastructure). These coefficients express the importance of the dependence of additional values in the development of geotourism at protected sites.

    Opis:
    Since psychology emerged as an independent field of knowledge, there has been no consensus as to how it should develop, either, in the idiographic or nomothetic way. In the course of time, due to a commitment to what was seen as objectivity in science, the nomothetic approach came to dominate psychology. Thus, researchers used mostly quantitative psychometric methods to establish general rules of human behaviour. In doing so, the essence of nomothetic research is to be extremely careful when interpreting results not to make a reasoning mistake such as the ecological fallacy, as may happen when a researcher draws conclusions about nature of the individual in the group based on average results of the whole group. In the article, we presented two methods for longitudinal research designs which address this problem, and give more idiographic information about participants; via the Reliable Change Index and the Modified Brinley Plot. Finally, we provide a IBM SPSS Statistics syntax automatizing the whole process of computation for these new features.

    Opis:
    This study takes its departure in the difficulties to recruit and retain qualified senior seafarers in the Swedish shipping sector. The study focus is on seafarers’ motivation at work for the specific shipping company (organizational commitment), and seafarers’ motivation towards their occupation (occupational commitment), in times of flagging out. It was hypothesized that the youngest seafarers and the oldest may be most sensitive to foreign registration of ships. Statistical analyses were employed, using a survey material of 1,309 Swedish seafarers randomly collected in 2010 from a national register of seafarers. The results of the analyses show that flagging-out imposes a significant decline in organizational commitment for all seafarers. This decline is related to the perception of the social composition of crew. In addition, the oldest seafarers (age 55+) demonstrate diminished occupational commitment under a foreign flag. This decline is related to the degree of satisfaction with the social security structure. Occupational commitment among the youngest seafarers (age 19-30) is not affected by the nationality of flag. However, this type of commitment is decreasing by the time served on the same ship. This effect is partly related to a decline in satisfaction with the work content. In the concluding discussion, the findings are discussed in more details and recommendations are put forward.

    Opis:
    Moroccan companies seek to be competitive worldwide by improving quality, productivity, and customer satisfaction. Lean Manufacturing and Six Sigma are the most popular methodologies for continuous improvement in companies. The objective of this article is to determine the impact of Six Sigma and Lean Manufacturing on the performance of different companies. The data was collected by a questionnaire sent to the various companies and industries in Morocco. 45 companies responded to this study, divided into several sectors. The criteria of this study are based on two levels: Financial and operational performance. A statistical study is carried out by SPSS software to analyze and interpret the collected results. The results of this study show that companies using Six Sigma and Lean Manufacturing methodologies have a positive financial and operational performance compared to companies that only use Lean Manufacturing or companies that do not use Six Sigma or Lean Manufacturing. Therefore, the combination of Six Sigma and Lean manufacturing is the ideal and perfect approach for the continuous improvement of different companies.

    Opis:
    This concept paper described the process of bridging the gaps in one of the methods for determining wheel over point (WOP). WOP is a marking made on charted courses to indicate a point at which a ship should change course. Identifying WOP is vital to avoid the vessel overshooting the planned track. One method for determining WOP is the advanced transfer technique. However, two issues were identified while reviewing this technique. Therefore, an improved mathematical model could be developed to overcome these problems. A manoeuvring analysis using a ship simulator will be performed to test the developed mathematical model's efficacy. The data obtained from the simulation study can be validated further by its adherence to the cross track limit, reduction in percentage change, and using IBM SPSS for the Mann-Whitney U test. The developed mathematical model is expectantly capable of producing a better track-keeping function and suitable for use onboard a cargo ship. The mathematical model also could be implemented as an algorithm in the Electronic Chart Display and Information System to help navigators make more efficient course changes.

    Opis:
    Sustainable water resources management and community engagement are essential for water security. Referring to the above context, this study proposed to carry out an assessment of community engagement for irrigation water management in the Nam Haad Left Irrigation Project (NHLIP). The household and community level practices and the farmers’ levels of participation in irrigation water management of the NHLIP were carefully considered. From respondents’ responses, the results revealed that a husband-wife partnership plays a remarkable role in irrigation water management of the NHLIP for rice farming. The results also proved that most of the respondents engage with a high participation level in managing irrigation water of the NHLIP project as illustrated by a high score of 3.80 on the five-point Likert scale. To determine the significance of each activity on farmers’ levels of participation in irrigation water management of the NHLIP, a stepwise multiple regression analysis was employed and the standardized regression equation for determining overall participation levels can be presented as: Y = 0.538x1 + 0.831x8 + 0.534x14 + 0.607x18 + 7.572. Finally, the outcomes of this study indicated the willingness of participation in cooperating and supporting the activities related to the improvement and management of the NHLIP project.
    Dla bezpieczeństwa wodnego istotne są zrównoważone zarządzanie zasobami wody i zaangażowanie społeczeństwa. W badaniach prezentowanych w niniejszej pracy dokonano oceny zaangażowania społeczności w zarządzanie nawodnieniami w ramach projektu Nam Haad Left Irrigation Project (NHLIP). Szczegółowo rozważano praktyki na poziomie gospodarstwa domowego i społeczności lokalnej oraz poziom uczestnictwa rolników w zarządzaniu nawodnieniami. Wyniki uzyskane z odpowiedzi respondentów wskazują, że znaczący udział w gospodarowaniu wodą do nawodnień upraw ryżu w ramach projektu mają mąż i żona. Wyniki świadczą również, że większość respondentów uczestniczy z dużym zaangażowaniem w projekcie, czego dowodem jest wysoka punktacja (3,80) w pięciostopniowej skali Likerta. Do określenia istotności każdego rodzaju aktywności i udziału rolnika w zarządzanie nawodnieniami w ramach projektu NHLIP zastosowano krokową regresję wieloraką, a standaryzowane równanie regresji opisujące poziom całkowitego zaangażowania ma postać: Y = 0,538x1 + 0,831x8 + 0,534x14 + 0,607x18 + 7,572. Podsumowując, wyniki badań wskazują chęć udziału i współpracy w ulepszaniu i zarządzaniu projektem NHLIP.

    Opis:
    One of the methods of efficient course alteration is through the accurate identification of the WOP by ATT. ATT is widely used by mariners worldwide, and recently, the technique has been restructured and enhanced into ATMM. To prove the efficacy of ATMM over ATT, a few types of ships have been used to carry out the manoeuvring analysis. This study extends the analysis by using a bulk carrier ship. A ship simulator was used for a manoeuvring simulation study, which was carried out to verify the differences between these two methods. Throughout the manoeuvring simulation study, XTD data for each simulation was monitored and verified by XTL compliance, percentage variation, and the Wilcoxon-Mann Whitney U Test via IBM SPSS. It was found that the ATMM can produce a significantly improved WOP compared to ATT and is suitable to be used onboard a bulk carrier ship. This research's finding is expected to contribute as evidence to strengthen ATMM's efficiency so that it can be accepted as an ECDIS algorithm for ship navigation.
