Hammerhead shark is a type of predator shark belongs to the family of Sphyrnidae. This shark is so aggressive in hunting prey such as fish, squid, and shrimp. The hammerhead shark in Indonesia is included in Appendix II of CITES and has been a special concern in the field of capture fisheries. The aim of the study was to see the size spread, the number of catches, the first size caught, the age growth and the genital ratio of the hammerhead sharks caught with the base fish net. The study was conducted from October to December 2019. The shark measurement was performed once in 2 weeks. Sharks caught by the gills of the base (buttom gilt net) were measured using a roll meter. The collection of hammerhead sharks included total length (TL), number of catches and genital ratio. The analysis was done descriptively using the ELEFAN I existing on Sofwere FiSAT II. The results showed that the hammerhead sharks caught with an gill net of 65 tails from October to December 2019 were taken on the male genital. The total size spread of female malletic sharks were between 61.5-131.5 cm and male hammering sharks between 61.5-111.5 cm. The morphologically spread of the female hammerhead was relatively longer than the male shark. The male hammerhead shark was first captured at a length of 117.9 cm and a female hammerhead shark at a size of 106.2 cm. Hammerhead shark growth by following the curve of von Bertalanffy mallet were male Lt = 138,08 (1-exp (-0.480 (t + 0.0487)) and female mallet shark Lt = 138,08 (1-exp (-0.430 (t + 0.0434)). Such equations can be known by using the relationship curve model between the age and length of fish.

The by-catch on the gill net fisheries is the current global fisheries problems and issues. This study aimed to analyze by-catch composition of fishery eel catfish (Plotosidae) in Kolono Bay, Southeast Sulawesi. Sampling was done monthly from April to July 2019, with bottom experimental gillnets of ¾, 1¼, 1½, 1 ¾, and 2 inches mesh sizes. The highest proportion of catches was found in by-catch (62.72%) than the main target, the family Plotosidae (37.28%). The by-catch includes 23 families consisting of two groups namely the useable by-catch 55.57% (19 families) and discarded by-catch 7.15% (4 families). Out of these 23 families, 44 species belong to the Least Concern (LC) and 24 species Not Evaluated (NE) categories on the IUCN red list 2019. The results showed that the use of bottom gillnets in eel catfish fisheries has a low selectivity which is characterized by high diversity and low dominance of by-catch.

Rajungan (Portunus peiagicus'' merupakan salah salu sumber daya hayati laut yang banyak dimanfaatkan oleh nelayan tradisionai. Rajungan di Teluk Jakarta selain sebagai sasaran penangkapan pada bubu cian jaring rajungan, juga tertangkap dengan sero, bagan, dan jaring arad Penelitian ini dilakukan pada tahun 2006 dengan tujuan untuk memperoleh informasi parameter stok dan selektivitas beberapa alat tangkap rajungan. Hasil pengamatan menunjukkan bahwa rajungan yang terlangkap mempunyai iebar karapas 4.16-11,9 cm dan boboi anlara 5.'1-113 g. Rajungan pertama kali tertangkap (Lcuo,o) pada sero, bagan, bubu, jaring rajungan, dan iaring arad pada ukuran lebar karapas 6,3: 7,3: 8,54; 8,96; dan 8,69 cm. Hampir semua (>95%i ralungan yang tertangkap dengan sero dan bagan merupakan rajungan kecil. Raiungan dewasa yang tertangkap pada jalng arad, bubu, dan Jaring rajungan diperoleh 4l, 66, dan 68%. Perbandingan keiamin jantan terhadap betina tidak sama pada alat tangkap yang digunakan. Hubungan antara lebar karapas dan panjang karapas pada sero, bagan, dan bubu rajungan mengikuti persamaan CW=o,4446 CL+0,1892 1r=3,9;. CW=o.431 4CL+0,347 5 (r=0,84J, dan CW=0,471 8C1+0,1 843 (r=0,83). Swimming crab, Portunus pelagicus ls one ot marine organism resources, intensively exploiled by aftisanal flsheres. fills crabis targeled species of trap and monofilalnent gili net and also as by catch of guiding barrier trap. fixed lift net. and monofilament gill net. The study was conducted in Jakarta Bay in 2006. The ob.tecti\/es of this study are to detemline papL ation parameters and seieclivity of swimmhg crab on several fishing gears used in Jakarta Bay. The swimning crabs werc caLtgl)t between 4.16-11 .9 cm in carapace widlh and between 5.1-113 g in weight. ihe firct captured (Lc sa-) of swimming crab caught by guiding barrier trap, fixed lift net, collapsible trap, beach se//]e. and monofilament gill net were 6.3, 7.3, 8.54. 8.69. and for 8.96 cnt. respectively. Guiding bamer trap and fixed iift net caught small crab for more than 95%.

According to the intergenerational solidarity model, family members who share similar values about family obligations should have a closer relationship and support each other more than families with a lower value consensus. The present study first describes similarities and differences between two family generations (mothers and daughters) with respect to their adherence to family values and, second, examines patterns of relations between intergenerational consensus on family values, affectual solidarity, and functional solidarity in a sample of 51 mother-daughter dyads comprising N = 102 participants from Luxembourgish and Portuguese immigrant families living in the Grand Duchy of Luxembourg. Results showed a small generation gap in values of hierarchical gender roles, but an acculturation gap was found in Portuguese mother-daughter dyads regarding obligations toward the family. A higher mother-daughter value consensus was related to higher affectual solidarity of daughters toward their mothers but not vice versa. Whereas affection and value consensus both predicted support provided by daughters to their mothers, affection mediated the relationship between consensual solidarity and received maternal support. With regard to mothers, only affection predicted provided support for daughters, whereas mothers’ perception of received support from their daughters was predicted by value consensus and, in the case of Luxembourgish mothers, by affection toward daughters.

The objective of this paper is to find the relationship between family firms’ CSR engagement and their non-family member employees’ organisational identification. Drawing upon the existing literature on social identity theory, corporate social responsibility and family firms, the author proposes that family firms engage actively in CSR programs in a balanced manner to increase non-family member employees’ organisational identification. The findings of the research suggest that by developing and implementing balanced CSR programs, and actively getting engaged in CSR activities, family firms may help their non-family member employees better identify themselves with the firms. The article points out that due to unbalanced CSR resource allocation, family firms face the problem of inefficient CSR program implementation, and are suggested to switch alternatively to an improved scheme. Family firms may be advised to take corresponding steps to select right employees, communicate better with non-family member employees, use resources better and handle firms’ succession problems efficiently. The paper extends employees’ identification and CSR research into the family firm research domain and points out some drawbacks in family firms’ CSR resource allocation while formerly were seldom noticed.

Children, brought up in foster families, experience various problems (diffi culties in interpersonal relationships with parents, diffi culties in communicating with peers, emotional instability), which lead to confl icts, quarrels, running away from home, destructive phenomena, etc. One of the eff ective forms of working with children brought up in foster families is individual counselling. Individual counselling is used by various specialists (psychologists, educators, psychotherapists), where a special place is taken by a social educator. His or her activity involves the implementation of social-protective, preventive, educational, informational, advisory functions. In the process of organizing individual counseling, the social educator takes into account the social situation of the family and the child, personal characteristics, social conditions, social and cultural characteristics and the nature of the relationship with the social environment. To organize individual counseling, a social educator needs to master various and eff ective techniques, and take into account a number of recommendations. An analysis of the literature and practical socio-pedagogical experience led to an understanding of the insuffi cient degree of elaboration of this issue. The purpose of this article was the solution to this problem.

This chapter examines the sociocognitive dimensions of cultural categorizations of deservingness. The social issue of poverty has been a persistent source of debate in the American system of policy development, influenced by conceptual distinctions between the “haves” and “have-nots,” “working moms” and “unemployed dads,” and the “deserving poor” and the “undeserving poor.” Although there is a wealth of literature discussing the ideological underpinnings of stratification systems, these discussions often focus on categorical distinctions between the poor and the nonpoor, with much less discussion of distinctions made among the poor. Moreover, while scholars of culture and policy have long referenced the importance of cultural categories of worthiness in policy development, the theoretical significance of these distinctions has been largely understudied. I expand the discourse on the relationship between cultural representations of worth and social welfare policy by exploring how these categories are conceptualized. Drawing on analytical tools from a sociology of perception framework, I create a model that examines deservingness along continuums of morality and eligibility to highlight the taken-for-granted cultural subtleties that shape perceptions of the poor. I focus on social filters created by norms of poverty, welfare, and the family to explore how the deserving are differentiated from the undeserving.
