This research is formulating the cause of agency conflict into three factors. The first one is agent unsatisfactory on the existing compensation system. The second is the high ratio of free cash flow in the company. The last is the absence of good monitoring on the company operation. Based on those three factors, this research aims to find a full perspective of these occurrences. One of the tools to investigate it is using EVA® as investigator tools, which is relatively new as a performance measurement in Emerging Market. The proxy variables on agency conflict are new investment ratio and total asset turn over. The control variables are dividend payout ratio and leverage. There are two research questions that being addressed in this research. The first, if there are any differences in agency conflict proxies between companies that have positive EVA® in their performance and companies with negative EVA®. The Second is to analyze if EVA® has significant role to influence the behavior of manager which tend to trigger the agency conflict within the company. The Methodology of this research was paired t-test data comparison between positive EVA companies and negative EVA. In addition, we analyzed the relationship of variable within the model with Data pool from 2002 until 2011To sum up the methodology; we tested the model with robustness test and Causality Test as well. The research finds out that Manager in companies with better EVA® tend to have lower agency conflict level. In conclusion, EVA® is strongly supporting the control variable in explaining its influence on dependent variables or agency conflict proxies.

Loligo chinensis merupakan salah satu jenis cumi-cumi yang memiliki nilai ekonomis penting di TPI Tambak Lorok Semarang. Produksi cumi-cumi merupakan hasil tangkapan dari alam, upaya penangkapan yang semakin tinggi dapat menyebabkan penurunan stok sumberdaya cumi-cumi. Tujuan penelitian ini adalah untuk mengetahui aspek biologi L.chinensis yang ada di Tambak Lorok yang meliputi hubungan panjang berat, faktor kondisi, dan pola pertumbuhan. Penelitian ini dilaksanakan pada bulan Juni-Juli 2020. Analisis data yang digunakan dalam penelitian adalah regresi linier sederhana dari log PM (panjang mantel) dan log W (weight) untuk mengetahui hubungan panjang beratnya. Nilai hubungan panjang berat L.chinensis mempunyai persamaan W = 0,00048L2,4921 untuk keseluruhan sampel, W = 3,237L0,84 pada betina dan W = 3,29L0,827 pada jantan dengan nilai slope (b) 2,4921; 0,84; dan 0,827. Nilai slope tersebut menunjukkan bahwa pertumbuhan L.chinensis bersifat alometrik negatif. Nilai faktor kondisi (Kn) = 1,064 pada keseluruhan sampel, Kn = 1,713 pada betina dan Kn = 1,63 pada jantan, nilai tersebut menunjukkan spesies ini tergolong memiliki badan yang kurus. Pertumbuhan panjang mantel (PM) L.chinensis tumbuh lebih lambat dibanding organ tubuh lain, kecuali terhadap berat tubuhnya. Loligo chinensis is one type of squid that has economic value crucial in the Tambak Lorok Semarang. Squid production mainly comes from nature, high fishing effort can cause a decrease in squid resource stock. The purpose of this study is to know the biological aspect L.chinensis in the Tambak Lorok include long weight relationships, condition factors, and the quality of alometry growth. The study was carried out in June-July 2020. The data analysis used is simple linear regression from the PM’s log (mantle length) and log W (weight) to know the relationship of its weight length. The relationship value between total length and total weight of L.chinensis has a W = 0,00048L2,4921 equation for the entire sample, W = 3,237L0,84 in the female and W = 3,29L0,827 in the male with slope (b) 2,4921; 0,84; and 0,827. Value slope shows the growths L.chinensis is negative alometrice. The value of the condition factor (Kn) = 1,064 in the entire sample, Kn = 1,713 in the female and Kn = 1,63 in the male. The value suggests that the species is thick-skinned. The growth of the mantle length (PM) of L.chinensis grows slower than other organs of the body, except for its total weight.

This study was made to examine the relationship between Economic Value Added (EVA®) and Market Value Added (MVA) with the reported earnings. Thus, the purpose is to gain better understanding in the use of EVA and MVA in relation to the reported earnings in certain purposes from different regression models. With the sample of 40 Indonesian listed companies in Indonesia Stock Exchange from year 2004 to 2007, the hypothesis testing is used to find the relationships among variables. The author use formula for calculating EVA and MVA to be use in four models of regression analysis against reported earnings. This study found evidence in the relationships between EVA and MVA with reported earnings, and the highest correlation among the models is relationship within the same year period, which can be used for evaluation purposes. Only the relationship of the EVA in the previous year and reported earnings changes is proved not significant. Still, MVA is more significant in explaining its relationship with reported earnings rather than EVA. The author concludes that in general, Indonesian listed companies still produces negative EVA. On the other hand, while the EVA and MVA are proved to have correlation with reported earnings, the result for EVA is lower than MVA. Therefore, there is still not enough evidence that EVA can be used to explain the reported earnings effectively other than MVA.

In this paper we examine whether Economic Value Added (EVATM) is a good predictor of shareholder value creation (SVC) for a group of Latin American companies. We also examine whether EVATM is a better predictor of SVC than competing accounting-based measures of managerial performance. The relationship of these predictors to SVC is paramount in a study of factors influencing shareholder value creation such as the compensation of a firm’s executives. Our results show strong correlations between EVATM and SVC. They also indicate that EVATM outperforms competing measures even after controlling for the potential effects that these last metrics have on SVC. Moreover, they reveal different levels of SVC sensitivity to changes in EVATM across countries and significant differences in EVA’s association with SVC across industries.

Job stressors in organizational studies are commonly known as role stressors. These include role overload (RO), role conflict (RC), role ambiguity (RA) and job insecurity (JI). We explored the predicting role of these stressors on the overall level of job stress (JS) and job satisfaction (JSF). Moreover, we tested the role of JS as a mediator between the relationship of role stressors and JSF in a multinational corporation (MNC) in a non-western collectivist context (Pakistan). We obtained data through field surveys from 173 engineering employees from the electrical, mechanical, safety and chemical divisions. Role stressors significantly predicted overall level of JS and JSF. JS was also found to partially mediate the relationship between role stressors and JSF. The study findings suggest that foreign ownership needs to focus not only on the economic value, but also the organizational and job design to mitigate the detrimental role of selected stressors. The results of this study have important implications for MNCs in general, and in developing countries in particular. Theoretical and managerial implications are discussed with recommendations.

Rajungan (Portunus pelagicus) memiliki nilai ekonomi tinggi, tetapi keberadaannya secara alami berhadapan dengan tingkat penangkapan yang semakin meningkat. Pesatnya perkembangan perusahaan eksportir rajungan dengan bahan baku yang bersumber dari hasil tangkapan nelayan, mengakibatkan sangat banyaknya nelayan yang melakukan penangkapan. Penangkapan rajungan dengan frekuensi tinggi dan terus-menerus tanpa memperhatikan ukuran serta kondisi rajungan, berpotensi mengurangi stok rajungan di perairan. Penelitian ini bertujuan untuk mengetahui distribusi ukuran, serta hubungan lebar karapas dengan berat rajungan yang didaratkan dari perairan Jobokuto, Jepara. Hasil dari penelitian ini menunjukkan, dari 1500 rajungan yang diamati diketahui bahwa distribusi lebar karapas berkisar 10,50-11,30 cm, dan berat berkisar  75-104 gram. Hubungan lebar karapas dengan  berat rajungan menghasilkan nilai b sebesar 1,68 untuk rajungan jantan dan 2,80 untuk rajungan betina, sehingga baik rajungan jantan maupun betina pertumbuhannya bersifat allometrik negatif. Sifat pertumbuhan ini menunjukkan bahwa pertumbuhan lebar karapas lebih cepat dibandingkan pertumbuhan berat rajungan. Persentase penggunaan alat tangkap oleh nelayan rajungan Jepara adalah Bubu (91%), dan Jaring (9%).The blue swimming crab (Portunus pelagicus) has a high economic value, but its existence is naturally faced with increasing fishing rates. The rapid development of crab exporters with raw materials sourced from fishermen's catches has resulted in very many fishers making arrests. Catching the crab with high frequency and continuously without regard to the size and condition of the crab has the potential to reduce the crab stock in the waters. This research aimed to determine the size distribution, as well as the relationship of carapace width to the weight of the crab,  landed from the seas of Jobokuto, Jepara. The results of this study indicated that of the 1500 crabs observed, the distribution of carapace width ranged from 10.50 to 11.30 cm, and the weight ranged from 75 to 104 grams. The relationship between carapace width and crab weight had a value of b of 1.68 for male crabs and 2.80 for female crabs so that both male and female crabs have negative allometric growth. This growth characteristic showed that carapace width growth is faster than the growth of crab weight. The percentage of fishing gear used by Jepara crab fishermen is Bubu (91%), and Net (9%).
