ABSTRAK Kelangsungan hidup organisme dipengaruhi oleh keseimbangan antara kandungan ion cairan tubuh dengan kandungan ion lingkungannya. Apabila gradient osmotik antara cairan tubuh dengan media lingkungan terlalu tinggi maka menyebabkan proses fisiologis terganggu, stress bahkan mengalami kematian (mortality) massal. Tujuan Penelitian ini yaitu mengetahui tingkat kelayakan kualitas air untuk budidaya udang vaname, menganalisis hubungan osmolaritas dan Tingkat Kerja Osmotik (TKO) pada udang vaname, dan mengetahui faktor kondisi udang vaname dalam kaitannya dengan TKO dan osmolaritas media. Penelitian ini dilaksanakan pada bulan November-Desember 2018. Metode penelitian yang digunakan adalah metode studi kasus dan metode deskriptif dengan metode pengukuran osmolaritas menggunakan alat Automatic Microosmotic Roebling. Sampel udang yang digunakan sebanyak 30 ekor udang vaname yang berasal dari 3 tambak yang ada di desa Mojo Ulujami Pemalang. Hasil penelitian ini menunjukkan osmolaritas media sangat berpengaruh terhadap tingkat kerja osmotik pada udang vaname di tambak intensif desa Mojo. Pertumbuhan udang vaname pada tambak intensif desa Mojo bersifat allometrik positif  dengan pola osmoregulasi hipoosmotik dengan nilai b=3.0618 dan nilai  faktor kondisi (Kn) = 1,621637. Hasil penelitian didapatkan nilai osmolaritas media pada tambak intensif udang vaname di Mojo pada salinitas 200/00 berkisar 616-618 (mOsm/l H2O) dan rata-rata TKO sebesar 37,36 (mOsm/l H2O). Tingkat kelayakan perairan pada tambak intensif udang vaname desa Mojo dikategorikan cukup mendukung tetapi perlu adanya perlakuan lebih lanjut. ABSTRACT The survival of an organism is affected by a balance between the content of ionic body fluids and the ion content of the environment. If the osmotic gradient between body fluids and environmental media is too high, the physiological process will be disrupted, stress will even experience mass mortality. The purpose of this study was to determine the level of feasibility of water quality for vaname shrimp farming, analyze the relationship of osmolarity and Osmotic Working Level (TKO) in vaname shrimp, and determine the factors of vaname shrimp conditions in relation to TKO and media osmolarity. This research was conducted in November-December 2018. The research method used was a case study method and descriptive method with a method of measuring osmolarity using an Automatic Microosmotic Roebling tool. Shrimp samples were used as many as 30 vaname shrimp from 3 ponds in Pemalang Mojo Ulujami village. The results of this study indicate that the osmolarity of the media greatly influences the level of osmotic work in vaname shrimp in Mojo intensive ponds. The growth of vaname shrimp in intensive ponds in Mojo village is allometric positive with a hypoosmotic osmoregulation pattern with a value of b = 3.0618 and a ponderal index (Kn) = 1 , 621637. The results showed that the media osmolarity values in the vaname shrimp intensive ponds in the Mojo at 200/00 salinity ranged from 616-618 (mOsm /l H2O) and the average TKO was 37.36 (mOsm / H2O). The level of feasibility of waters in intensive ponds of vaname shrimp in Mojo village is categorized as sufficiently supportive but needs further treatment.

The retail market in Vietnam continues to grow with the entry of foreign retail brands and the strong rise of domestic businesses in expanding distribution networks and conquering consumer confidence. The appearance of more retail brands has created a fiercely competitive market. Based on the outcomes of previous research results on brand choice intention combined with a customer survey, the paper proposes an analytical framework and scales to examine the relationship of five elements including store image, price perception, risk perception, brand attitudes, brand awareness and retail brand choice intention with a case study of the Hanoi-based Circle K convenience store chain. These five elements are the precondition for retail businesses to develop their brands so as to attract customers.

Several studies have shown that the success of interregional cooperation may be influenced by coordination, commitment, participation, variance of cooperation, structure, format of cooperation, and political will. Nevertheless, these factors do not stand alone since actor relations as a determining aspect is capable of driving those factors effectively. This article aims to examine the aspect of actor relations as a contributing factor that determines successful cooperation among regions. This is a qualitative research with the policy of inter-regional cooperation of the Banjarbakula Program, South Kalimantan Province from February 2017 to February 2018, set as its object of study. The result of this study states that the success of inter-regional cooperation is influenced by the relationship of actors in development factors as suggested by previous experts. The actors involved in the inter-regional cooperation examined in this case had become triggers of coordination, commitment, and participation toward success and failure, as well as the effectiveness of regional cooperation policy. Structural obstacles, ego-centric character, minimum budget availability, and non-visionary planning could be overcome as long as actor relations were properly managed.

AbstractThis article considers the relationship of international law and the media through the prism of human rights. In the first section the international regulation of the media is examined and visions of good, bad, and new media emerge. In the second section, the enquiry is reversed and the article explores the ways in which the media is shaping international legal forms and processes in the field of human rights. This is termed the ‘mediatization of international law’. Yet despite hopes for new media and the Internet to transform international law, the theoretical work of Jodi Dean warns of the danger to democracy of commodification through the spread of ‘communicative capitalism’.

We used spectral analysis and event-triggered averaging to determine the effects of chemical inactivation of the medullary lateral tegmental field (LTF) on 1) the relationship of intratracheal pressure (ITP, an index of vagal lung inflation afferent activity) to sympathetic nerve discharge (SND) and phrenic nerve activity (PNA) and 2) central respiratory rate in paralyzed, artificially ventilated dial-urethane-anesthetized cats. ITP-SND coherence value at the frequency of artificial ventilation was significantly ( P < 0.05; n = 18) reduced from 0.73 ± 0.04 (mean ± SE) to 0.24 ± 0.04 after bilateral microinjection of muscimol into the LTF. Central respiratory rate was unexpectedly increased in 12 of these experiments (0.28 ± 0.03 vs. 0.95 ± 0.25 Hz). The ITP-PNA coherence value was variably affected by chemical inactivation of the LTF. It was unchanged when central respiratory rate was also not altered, decreased when respiratory rate was increased above the rate of artificial ventilation, and increased when respiratory rate was raised from a value below the rate of artificial ventilation to the same frequency as the ventilator. Chemical inactivation of the LTF increased central respiratory rate in four of six vagotomized cats but did not significantly affect the PNA-SND coherence value. These data demonstrate that the LTF 1) plays a critical role in mediating the effects of vagal lung inflation afferents on SND but not PNA, 2) helps maintain central respiratory rate in the physiological range, but 3) is not involved in the coupling of central respiratory and sympathetic circuits.

Managers play an important role in organizations. They are the persons who formulate and implement policies, plans etc in the organization. Managers are the first to be contacted for suggestions with regard to overall information about the organization. Taking into consideration the importance of managers in the organization and a critical review of literature which revealed that the study on work motivation, burnout and intention to leave has not been conducted so far on the top level managers of garment industry of Delhi and NCR, the researcher found a gap to be filled by  conducting investigation on this sample for the variables in question. So the sample of the present study consists of top level managers of garment industry of Delhi and NCR. Thus, a convenient sampling method was used for drawing the sample from 60 garment export houses of Delhi and 40 of NCR. This paper gives a deep insight of work motivation, burnout and intention to leave for the top level managers of the garment industry of Delhi/NCR. In this paper we have checked the relationship of all dimensions of work motivation with the dimensions of burnout and intention to leave and have observed that all dimensions of work motivation have some more or less relationship with each dimension of burnout but neither of the dimensions of work motivation or total work motivation have any relationship with intention to leave. So even if top level managers leave their current job they don’t leave because of lack of work motivation.

El cambio de modelo urbano asumido durante el siglo XX, trajo un sinnúmero de problemas como la priorización del vehículo, por lo que en la última década han surgido esfuerzos para dotar de importancia al ciudadano de a pie, en el espacio público. Esta investigación estudió las condiciones físico-espaciales de un corredor urbano donde el modelo centrado en el vehículo se acentúa, con la fnalidad de generar posibles estrategias que reviertan esta situación. Se tomó como caso de estudio a la Av. 24 de Mayo, en Azogues, y se lo analizó mediante una metodología mixta, que evaluó, detalladamente, tres zonas de estudio, determinando que la falta de accesibilidad y conectividad y el modelo de movilidad defendido por la ciudadanía, en general, infuyen directamente en las condiciones del espacio público peatonal y por ende en la habitabilidad urbana, perjudicando los desplazamientos a pie. Palabras clave: Espacio público; habitabilidad urbana; conectividad; accesibilidad; percepción. AbstractThe change of urban model assumed during the 20th century, brought countless problems such as the prioritization of vehicles, so in the last decade eforts have emerged to give importance to the citizen on foot in the public space. This original research studied the relationship of urban habitability with the physical-spatial conditions of an urban corridor, where the vehicle-centered model is accentuated, to generate possible strategies to reverse this situation.

Information systems development takes place within an economical context. However, the economical conditions, which shape systems development in practice, are hardly researched. In this paper we are investigating the question how a given price structure influences systems development projects. Our analysis is based on a multi case study and a Grounded Theory inspired research approach. Our work is informed by economic theories, which deal with the relationship of suppliers and customers and their mutual dependency. We thus apply principal-agent theory and economic game theory in form of the prisoner’s dilemma. As a result we provide three interlinked models for understanding the impact of pricing structure on systems development practice. The main elements of these models are pricing structure, risk distribution and price level, and opportunistic behavior. We discuss how these elements are interrelated and examine their impact on information systems development in practice.
